    As part of the Department of Energy's research and development effort to improve the monitoring capability of the planned Comprehensive Nuclear-Test-Ban Treaty international monitoring system, Lawrence Livermore Laboratory (LLNL) is testing and calibrating regional seismic discrimination algorithms in the Middle East, North Africa and Western Former Soviet Union. The calibration process consists of a number of steps: (1) populating the database with independently identified regional events; (2) developing regional boundaries and pre-identifying severe regional phase blockage zones; (3) measuring and calibrating coda based magnitude scales; (4a) measuring regional amplitudes and making magnitude and distance amplitude corrections (MDAC); (4b) applying the DOE modified kriging methodology to MDAC results using the regionalized background model; (5) determining the thresholds of detectability of regional phases as a function of phase type and frequency; (6) evaluating regional phase discriminant performance both singly and in combination; (7) combining steps 1-6 to create a calibrated discrimination surface for each stations; (8) assessing progress and iterating. We have now developed this calibration procedure to the point where it is fairly straightforward to apply earthquake-explosion discrimination in regions with ample empirical data. Several of the steps outlined above are discussed in greater detail in other DOE papers in this volume or in recent publications. Here we emphasize the results of the above process: station correction surfaces and their improvement to discrimination results compared with simpler calibration methods. Some of the outstanding discrimination research issues involve cases in which there is little or no empirical data. For example in many cases there is no regional nuclear explosion data at IMS stations or nearby surrogates. We have taken two approaches to this problem, first finding and using mining explosion data when available, and

    Mattison, T.S.

    1988-10-01

    The study of electron-positron (e + e/sup /minus//) annihilation in storage ring colliders has been very fruitful. It is by now well understood that the optimized cost and size of e + e/sup /minus// storage rings scales as E(sub cm//sup 2/ due to the need to replace energy lost to synchrotron radiation in the ring bending magnets. Linear colliders, using the beams from linear accelerators, evade this scaling law. The study of e/sup +/e/sup /minus// collisions at TeV energy will require linear colliders. The luminosity requirements for a TeV linear collider are set by the physics. Advanced accelerator research and development at SLAC is focused toward a TeV Linear Collider (TLC) of 0.5--1 TeV in the center of mass, with a luminosity of 10/sup 33/--10/sup 34/. The goal is a design for two linacs of less than 3 km each, and requiring less than 100 MW of power each. With a 1 km final focus, the TLC could be fit on Stanford University land (although not entirely within the present SLAC site). The emphasis is on technologies feasible for a proposal to be framed in 1992. Linear collider development work is progressing on three fronts: delivering electrical energy to a beam, delivering a focused high quality beam, and system optimization. Sources of high peak microwave radio frequency (RF) power to drive the high gradient linacs are being developed in collaboration with Lawrence Berkeley Laboratory (LBL) and Lawrence Livermore National Laboratory (LLNL). Beam generation, beam dynamics and final focus work has been done at SLAC and in collaboration with KEK. Both the accelerator physics and the utilization of TeV linear colliders were topics at the 1988 Snowmass Summer Study. 14 refs., 4 figs., 1 tab

    Thomassen, K I; Holzrichter, J F [eds.

    1989-09-14

    With the appearance of reports on Cold Fusion,'' scientists at the Lawrence Livermore National Laboratory (LLNL) began a series of increasingly sophisticated experiments and calculations to explain these phenomena. These experiments can be categorized as follows: (a) simple experiments to replicate the Utah results, (b) more sophisticated experiments to place lower bounds on the generation of heat and production of nuclear products, (c) a collaboration with Texas A M University to analyze electrodes and electrolytes for fusion by-products in a cell producing 10% excess heat (we found no by-products), and (d) attempts to replicate the Frascati experiment that first found neutron bursts when high-pressure deuterium gas in a cylinder with Ti chips was temperature-cycled. We failed in categories (a) and (b) to replicate either the Pons/Fleischmann or the Jones phenomena. We have seen phenomena similar to the Frascati results, (d) but these low-level burst signals may not be coming from neutrons generated in the Ti chips. Summaries of our experiments are described in Section II, as is a theoretical effort based on cosmic ray muons to describe low-level neutron production. Details of the experimental groups' work are contained in the six appendices. At LLNL, independent teams were spontaneously formed in response to the early announcements on cold fusion. This report's format follows this organization.

    Tom Sugihara's scientific leadership over a period of almost four decades covered many areas. His early research at Clark dealt with fission yields measurements and radiochemical separations of fallout species in the marine environment. Tom pioneered many of the methods for detecting soft beta emitters and low levels of radioactivity. Studies of the behavior of radioactivity in the marine ecosystem were important adjuncts to Tom's nuclear science research at Clark University which emphasized investigations of nuclear reaction mechanisms. Among Tom's most important contributions while at Clark was his work with Matsuo and Dudey on the interpretation of isomeric yield ratios and fission studies with Noshkin and Baba. Tom's scientific career oscillated between research and administration. During the latter part of his career his great breadth of interests and his scientific open-quotes tasteclose quotes had a profound influence at LLNL in areas that were new to him, materials science and solid state physics

    This final report discusses Department of Energy-supported research funded through Lawrence Livermore National Laboratory (LLNL) which was performed as part of a collaboration between LLNL and Prairie View A and M University to develop part of the BaBar detector at the SLAC B Factory. This work focuses on the Instrumented Flux Return (IFR) subsystem of BaBar and involves a full range of detector development activities: computer simulations of detector performance, creation of reconstruction algorithms, and detector hardware R and D. Lawrence Livermore National Laboratory has a leading role in the IFR subsystem and has established on-site computing and detector facilities to conduct this research. By establishing ties with the existing LLNL Research Collaboration Program and leveraging LLNL resources, the experienced Prairie View group was able to quickly achieve a more prominent role within the BaBar collaboration and make significant contributions to the detector design. In addition, this work provided the first entry point for Historically Black Colleges and Universities into the B Factory collaboration, and created an opportunity to train a new generation of minority students at the premier electron-positron high energy physics facility in the US

  9. Review of LLNL Mixed Waste Streams for the Application of Potential Waste Reduction Controls

    2007-01-01

    In July 2004, LLNL adopted the International Standard ISO 14001 as a Work Smart Standard in lieu of DOE Order 450.1. In support of this new requirement the Director issued a new environmental policy that was documented in Section 3.0 of Document 1.2, ''ES and H Policies of LLNL'', in the ES and H Manual. In recent years the Environmental Management System (EMS) process has become formalized as LLNL adopted ISO 14001 as part of the contract under which the laboratory is operated for the Department of Energy (DOE). On May 9, 2005, LLNL revised its Integrated Safety Management System Description to enhance existing environmental requirements to meet ISO 14001. Effective October 1, 2005, each new project or activity is required to be evaluated from an environmental aspect, particularly if a potential exists for significant environmental impacts. Authorizing organizations are required to consider the management of all environmental aspects, the applicable regulatory requirements, and reasonable actions that can be taken to reduce negative environmental impacts. During 2006, LLNL has worked to implement the corrective actions addressing the deficiencies identified in the DOE/LSO audit. LLNL has begun to update the present EMS to meet the requirements of ISO 14001:2004. The EMS commits LLNL--and each employee--to responsible stewardship of all the environmental resources in our care. The generation of mixed radioactive waste was identified as a significant environmental aspect. Mixed waste for the purposes of this report is defined as waste materials containing both hazardous chemical and radioactive constituents. Significant environmental aspects require that an Environmental Management Plan (EMP) be developed. The objective of the EMP developed for mixed waste (EMP-005) is to evaluate options for reducing the amount of mixed waste generated. This document presents the findings of the evaluation of mixed waste generated at LLNL and a proposed plan for reduction

    2016-12-01

    High performance computing (HPC) has been a defining strength of Lawrence Livermore National Laboratory (LLNL) since its founding. Livermore scientists have designed and used some of the world’s most powerful computers to drive breakthroughs in nearly every mission area. Today, the Laboratory is recognized as a world leader in the application of HPC to complex science, technology, and engineering challenges. Most importantly, HPC has been integral to the National Nuclear Security Administration’s (NNSA’s) Stockpile Stewardship Program—designed to ensure the safety, security, and reliability of our nuclear deterrent without nuclear testing. A critical factor behind Lawrence Livermore’s preeminence in HPC is the ongoing investments made by the Laboratory Directed Research and Development (LDRD) Program in cutting-edge concepts to enable efficient utilization of these powerful machines. Congress established the LDRD Program in 1991 to maintain the technical vitality of the Department of Energy (DOE) national laboratories. Since then, LDRD has been, and continues to be, an essential tool for exploring anticipated needs that lie beyond the planning horizon of our programs and for attracting the next generation of talented visionaries. Through LDRD, Livermore researchers can examine future challenges, propose and explore innovative solutions, and deliver creative approaches to support our missions. The present scientific and technical strengths of the Laboratory are, in large part, a product of past LDRD investments in HPC. Here, we provide seven examples of LDRD projects from the past decade that have played a critical role in building LLNL’s HPC, computer science, mathematics, and data science research capabilities, and describe how they have impacted LLNL’s mission.

    1981-07-01

    Research programs at LLNL for 1981 are described in broad terms. In his annual State of the Laboratory address, Director Roger Batzel projected a $481 million operating budget for fiscal year 1982, up nearly 13% from last year. In projects for the Department of Energy and the Department of Defense, the Laboratory applies its technical facilities and capabilities to nuclear weapons design and development and other areas of defense research that include inertial confinement fusion, nonnuclear ordnances, and particle-beam technology. LLNL is also applying its unique experience and capabilities to a variety of projects that will help the nation meet its energy needs in an environmentally acceptable manner. A sampling of recent achievements by LLNL support organizations indicates their diversity

    Roberts, M.L.; Bench, G.S.; Brown, T.A.

    1996-05-01

    The AMS facility at Lawrence Livermore National Laboratory (LLNL) routinely measures the isotopes 3 H, 7 Be, 10 Be, 14 C, 26 Al, 36 Cl, 41 Ca, 59,63 Ni, and 129 I. During the past two years, over 30,000 research samples have been measured. Of these samples, approximately 30% were for 14 C bioscience tracer studies, 45% were 14 C samples for archaeology and the geosciences, and the other isotopes constitute the remaining 25%. During the past two years at LLNL, a significant amount of work has gone into the development of the Projectile X-ray AMS (PXAMS) technique. PXAMS uses induced characteristic x-rays to discriminate against competing atomic isobars. PXAMS has been most fully developed for 63 Ni but shows promise for the measurement of several other long lived isotopes. During the past year LLNL has also conducted an 129 I interlaboratory comparison exercise. Recent hardware changes at the LLNL AMS facility include the installation and testing of a new thermal emission ion source, a new multianode gas ionization detector for general AMS use, re-alignment of the vacuum tank of the first of the two magnets that make up the high energy spectrometer, and a new cryo-vacuum system for the AMS ion source. In addition, they have begun design studies and carried out tests for a new high-resolution injector and a new beamline for heavy element AMS

    2008, has been included as an appendix to the RMP Supplemental Information document. LLNL Site 200 is a research and development laboratory with infrastructure necessary to support its operations and personnel. Research and development activities at LLNL are focused on stockpile stewardship; achieving robust and vital scientific, engineering, and manufacturing capability; inertial confinement fusion; laser technology; materials and process science; computational and information sciences; basic sciences; engineering sciences; and biological sciences. Based upon CalARP Program regulations, guidance found in California Accidental Release Prevention Program (CalARP) Administering Guidance, Chapter 1, a review of facility specific documents, accident analyses summarized in this document and detailed in the LLNL Site 200 RMP Supporting Information document, LLNL has determined that each process meeting the CalARP threshold criteria meets the requirements for CalARP Program Level 1. In accordance with CalARP regulations, LLNL considers the natural segmentation of processes at Site 200 to be on a building basis and therefore consideration of inventory should be on a building basis rather than a 'site-wide' basis. Only those materials identified as equal to as or greater than the threshold quantities for the CalARP program on a building (process) level are reflected in this document. As such, materials and quantities reported in this document on a building (process) level will vary from materials and quantities reported in the LLNL Hazardous Materials Business Plan, Acutely Hazardous Material Registration Form on a site-wide level. For each process involving regulated quantities of lithium hydride, worst case accident analysis shows that the toxic endpoint lies within the site boundaries. These analyses document that the nearest public receptor is beyond the distance to a toxic or flammable endpoint. Refer to the LLNL Site 200 RMP Supporting Information document for a more

    For the past six years, the US Department of Energy, LLNL, and the ENEA, Rome, Italy, have participated in cooperative studies for improving a systems approach to an emergency response following nuclear accidents. Technology exchange between LLNL and the ENEA was initially confined to the development, application, and evaluation of atmospheric transport and diffusion models. With the emergence of compatible hardware configurations between LLNL and ENEA, exchanges of technology and ideas for improving the development and implementation of systems are beginning to emerge. This report describes cooperative work that has occurred during the past three years, the present state of each system, and recommendations for future exchanges of technology

    1990-05-01

    This document is the February 14, 1990 version of the LLNL Waste Minimization Program Plan (WMPP). Now legislation at the federal level is being introduced. Passage will result in new EPA regulations and also DOE orders. At the state level the Hazardous Waste Reduction and Management Review Act of 1989 was signed by the Governor. DHS is currently promulgating regulations to implement the new law. EPA has issued a proposed new policy statement on source reduction and recycling. This policy reflects a preventative strategy to reduce or eliminate the generation of environmentally-harmful pollutants which may be released to the air, land surface, water, or ground water. In accordance with this policy new guidance to hazardous waste generators on the elements of a Waste Minimization Program was issued. This WMPP is formatted to meet the current DOE guidance outlines. The current WMPP will be revised to reflect all of these proposed changes when guidelines are established. Updates, changes and revisions to the overall LLNL WMPP will be made as appropriate to reflect ever-changing regulatory requirements

    1994-12-01

    Strategic management of LLNL's research effort is addressed. A general framework is established by presenting the McKinsey/BCG Matrix Analysis as it applies to the research portfolio. The framework is used to establish the need for the diversification into new attractive areas of research and for the improvement of the market position of existing research in those attractive areas. With the need for such diversification established, attention is turned to optimizing it. There are limited resources available. It is concluded that LLNL should diversify into only a few areas and try to obtain full market share as soon as possible

    Lawrence Livermore National Security, LLC operates facilities at Lawrence Livermore National Laboratory (LLNL) where radionuclides are handled and stored. These facilities are subject to the U.S. Environmental Protection Agency (EPA) National Emission Standards for Hazardous Air Pollutants (NESHAPs) in Code of Federal Regulations (CFR) Title 40, Part 61, Subpart H, which regulates radionuclide emissions to air from Department of Energy (DOE) facilities. Specifically, NESHAPs limits the emission of radionuclides to the ambient air to levels resulting in an annual effective dose equivalent of 10 mrem (100 μSv) to any member of the public. Using measured and calculated emissions, and building-specific and common parameters, LLNL personnel applied the EPA-approved computer code, CAP88-PC, Version 4.0.1.17, to calculate the dose to the maximally exposed individual member of the public for the Livermore Site and Site 300.

    The LLNL chemical kinetics modeling group has been responsible for much progress in the development of chemical kinetic models for practical fuels. The group began its work in the early 1970s, developing chemical kinetic models for methane, ethane, ethanol and halogenated inhibitors. Most recently, it has been developing chemical kinetic models for large n-alkanes, cycloalkanes, hexenes, and large methyl esters. These component models are needed to represent gasoline, diesel, jet, and oil-sand-derived fuels.

  15. LLNL Waste Minimization Program Plan

    International Nuclear Information System (INIS)

    1990-01-01

    This document is the February 14, 1990 version of the LLNL Waste Minimization Program Plan (WMPP). The Waste Minimization Policy field has undergone continuous changes since its formal inception in the 1984 HSWA legislation. The first LLNL WMPP, Revision A, is dated March 1985. A series of informal revision were made on approximately a semi-annual basis. This Revision 2 is the third formal issuance of the WMPP document. EPA has issued a proposed new policy statement on source reduction and recycling. This policy reflects a preventative strategy to reduce or eliminate the generation of environmentally-harmful pollutants which may be released to the air, land surface, water, or ground water. In accordance with this new policy new guidance to hazardous waste generators on the elements of a Waste Minimization Program was issued. In response to these policies, DOE has revised and issued implementation guidance for DOE Order 5400.1, Waste Minimization Plan and Waste Reduction reporting of DOE Hazardous, Radioactive, and Radioactive Mixed Wastes, final draft January 1990. This WMPP is formatted to meet the current DOE guidance outlines. The current WMPP will be revised to reflect all of these proposed changes when guidelines are established. Updates, changes and revisions to the overall LLNL WMPP will be made as appropriate to reflect ever-changing regulatory requirements. 3 figs., 4 tabs

  16. The LLNL portable tritium processing system

    1995-01-01

    The end of the Cold War significantly reduced the need for facilities to handle radioactive materials for the US nuclear weapons program. The LLNL Tritium Facility was among those slated for decommissioning. The plans for the facility have since been reversed, and it remains open. Nevertheless, in the early 1990s, the cleanup (the Tritium Inventory Removal Project) was undertaken. However, removing the inventory of tritium within the facility and cleaning up any pockets of high-level residual contamination required that we design a system adequate to the task and meeting today's stringent standards of worker and environmental protection. In collaboration with Sandia National Laboratory and EG ampersand G Mound Applied Technologies, we fabricated a three-module Portable Tritium Processing System (PTPS) that meets current glovebox standards, is operated from a portable console, and is movable from laboratory to laboratory for performing the basic tritium processing operations: pumping and gas transfer, gas analysis, and gas-phase tritium scrubbing. The Tritium Inventory Removal Project is now in its final year, and the portable system continues to be the workhorse. To meet a strong demand for tritium services, the LLNL Tritium Facility will be reconfigured to provide state-of-the-art tritium and radioactive decontamination research and development. The PTPS will play a key role in this new facility

    The interaction of energetic electrons with highly charged ions is of great importance to several research fields such as astrophysics, laser fusion and magnetic fusion. In spite of this importance there are almost no measurements of electron interaction cross sections for ions more than a few times ionized. To address this problem an electron beam ion trap (EBIT) is being developed at LLNL. The device is essentially an EBIS except that it is not intended as a source of extracted ions. Instead the (variable energy) electron beam interacting with the confined ions will be used to obtain measurements of ionization cross sections, dielectronic recombination cross sections, radiative recombination cross sections, energy levels and oscillator strengths. Charge-exchange recombinaion cross sections with neutral gasses could also be measured. The goal is to produce and study elements in many different charge states up to He-like xenon and Ne-like uranium. 5 refs., 2 figs

    1998-01-01

    The goal of this LDRD project was to demonstrate the technical and economical feasibility of applying laser isotope separation technology to the commercial enrichment (>lkg/y) of stable isotopes. A successful demonstration would well position the laboratory to make a credible case for the creation of an ongoing medical and industrial isotope production and development program at LLNL. Such a program would establish LLNL as a center for advanced medical isotope production, successfully leveraging previous LLNL Research and Development hardware, facilities, and knowledge

    1982-02-12

    The Lawrence Livermore National Laboratory is involved in many facets of research ranging from nuclear weapons research to advanced Biomedical studies. Approximately 80% of all programs at LLNL generate hazardous waste in one form or another. Aside from producing waste from industrial type operations (oils, solvents, bottom sludges, etc.) many unique and toxic wastes are generated such as phosgene, dioxin (TCDD), radioactive wastes and high explosives. One key to any successful waste management program must address the following: proper identification of the waste, safe handling procedures and proper storage containers and areas. This section of the Waste Management Plan will address methodologies used for the Analysis of Hazardous Waste. In addition to the wastes defined in 40 CFR 261, LLNL and Site 300 also generate radioactive waste not specifically covered by RCRA. However, for completeness, the Waste Analysis Plan will address all hazardous waste.

    2011-08-01

    This review briefly summarizes recent Tai Chi research on physical benefits including balance and muscle strength and psychological benefits including attentiveness, sleep and anxiety. Cardiovascular changes following Tai Chi include decreased heart rate and blood pressure, increased vagal activity and decreased cholesterol. Pain syndromes that have been affected include fibromyalgia, osteoarthritis and rheumatoid arthritis. Autoimmune and immune conditions recently researched and reviewed here include osteoporosis, diabetes and HIV. Methodological problems with this research include the variability in forms (series of postures) used across studies as well as the intensity of the Tai Chi schedule. Further, most of the studies are based on within group changes rather than attention control group comparisons. Nonetheless, significant clinical improvements have been noted.

    To enable the regulatory review to be effectively undertaken by the regulatory body, there is a need for it to have ready access to information generated by research activities. Certain advantages have been seen to be gained by the regulatory body itself directly allocating and controlling some portion of these activities. The princial reasons for reaching this conclusion are summarised and a brief description of the Inspectorates directly sponsored programme outlined. (author)

  9. Yoga research review.

    Science.gov (United States)

    Field, Tiffany

    2016-08-01

    This paper is a review of empirical studies, review and meta-analysis publications on yoga from the last few years. The review includes demographics/prevalence of yoga as a practice, bibliometric analyses of the yoga publications and the use of yoga for physical fitness and cognitive function. Most of the studies reviewed here involve yoga effects on psychiatric and medical conditions. These include pregnancy, prenatal and postpartum depression; stress, PTSD, anxiety, and obesity; cardiovascular conditions including hypertension; pain syndromes including arthritis, headaches and low back pain; autoimmune conditions including asthma, type II diabetes and multiple sclerosis; immune conditions including HIV and breast cancer; and aging problems including balance, osteoporosis and Parkinson's. The methods and results of those studies are briefly summarized along with their limitations and suggestions for future research. Basically yoga has been more effective than control and waitlist control conditions, although not always more effective than treatment comparison groups such as other forms of exercise. More randomized controlled studies are needed in which yoga is compared to active exercise groups. Having established the physical and mental health benefits of yoga makes it ethically questionable to assign participants to inactive control groups. Shorter sessions should be investigated for cost-effectiveness and for daily practice. Multiple physical and physiological measures need to be added to the self-report research protocols and potential underlying mechanisms need to be further explored. In the interim, the studies reviewed here highlight the therapeutic effects of yoga, a practice that could come to be called yoga therapy. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Field, Tiffany

    2016-08-01

    In this review, massage therapy has been shown to have beneficial effects on varying conditions including prenatal depression, preterm infants, full-term infants, autism, skin conditions, pain syndromes including arthritis and fibromyalgia, hypertension, autoimmune conditions including asthma and multiple sclerosis, immune conditions including HIV and breast cancer and aging problems including Parkinson's and dementia. Although many of the studies have involved comparisons between massage therapy and standard treatment control groups, several have compared different forms of massage (e.g. Swedish versus Thai massage), and different active therapies such as massage versus exercise. Typically, the massage therapy groups have experienced more positive effects than the control or comparison groups. This may relate to the massage therapy providing more stimulation of pressure receptors, in turn enhancing vagal activity and reducing cortisol levels. Some of the researchers have assessed physical, physiological and biochemical effects, although most have relied exclusively on self-report measures. Despite these methodological problems and the dearth of research from the U.S., the massage therapy profession has grown significantly and massage therapy is increasingly practiced in traditional medical settings, highlighting the need for more rigorous research.

    Lawrence Livermore National Laboratory (LLNL) is the home of the world's highest current beam of keV positrons. The potential for establishing a national center for materials analysis using positron annihilation techniques around this capability is being actively pursued. The high LLNL beam current will enable investigations in several new areas. We are developing a positron microprobe that will produce a pulsed, focused positron beam for 3-dimensional scans of defect size and concentration with submicron resolution. Below we summarize the important design features of this microprobe. Several experimental end stations will be available that can utilize the high current beam with a time distribution determined by the electron linac pulse structure, quasi-continuous, or bunched at 20 MHz, and can operate in an electrostatic or (and) magnetostatic environment. Some of the planned early experiments are: two-dimensional angular correlation of annihilation radiation of thin films and buried interfaces, positron diffraction holography, positron induced desorption, and positron induced Auger spectroscopy

LIFTIRS produces a spatial format of 128x128 pixels, with spectral resolution arbitrarily variable up to a maximum of 0.25 inverse centimeters. Time resolution and spectral resolution can be traded off for each other with great flexibility. We will discuss recent measurements made with this instrument, and present typical images and spectra.

  19. Review of spheromak research

    Jarboe, T.R.

    1994-01-01

    Spheromak research from 1979 to the present is reviewed including over 160 references. Emphasis is on understanding and interpretation of results. In addition to summarizing results some new interpretations are presented. An introduction and brief history is followed by a discussion of generalized helicity and its time derivative. Formation and sustainment are discussed including five different methods, flux core, θ-pinch z-pinch, coaxial source, conical θ-pinch, and kinked z-pinch. All methods are helicity injections. Steady-state methods and rules for designing spheromak experiments are covered, followed by equilibrium and stability. Methods of stabilizing the tilt and shift modes are discussed as well as their impact on the reactor designs. Current-driven and pressure-driven instabilities as well as relaxation in general are covered. Energy confinement is discussed in terms of helicity decay time and βs limits. The confinement in high and low open-flux geometries are compared and the reactor implications discussed. (author)

    In the electric gun, the explosion of an electrically heated metal foil and the accompanying magnetic forces drive a thin flyer plate up a short barrel. Flyer velocities of up to 18 km/s make the gun useful for hypervelocity impact studies. The authors briefly review the technological evolution of the exploding-metal circuit elements that power the gun, describe the 100-kV electric gun designed at Lawrence Livermore National Laboratory (LLNL) in some detail, and present the general principles of electric gun operation. They compare the experimental performance of the LLNL gun with a simple model and with predictions of a magnetohydrodynamics code

  3. LLNL Livermore site Groundwater Surveillance Plan

    International Nuclear Information System (INIS)

    1992-04-01

    Department of Energy (DOE) Order 5400.1 establishes environ-mental protection program requirements, authorities, and responsibilities for DOE operations to assume compliance with federal, state, and local environmental protection laws and regulations; Federal Executive Orders; and internal DOE policies. ne DOE Order contains requirements and guidance for environmental monitoring programs, the objectives of which are to demonstrate compliance with legal and regulatory requirements imposed by federal, state, and local agencies; confirm adherence to DOE environmental protection polices; and support environmental management decisions. The environmental monitoring programs consist of two major activities: (1) measurement and monitoring of effluents from DOE operations, and (2) surveillance through measurement, monitoring, and calculation of the effects of those operations on the environment and public health. The latter concern, that of assessing the effects, if any, of Lawrence Livermore National Laboratory (LLNL) operations and activities on on-site and off-site surface waters and groundwaters is addressed by an Environmental Surveillance Program being developed by LLNL. The Groundwater Surveillance Plan presented here has been developed on a sitespecific basis, taking into consideration facility characteristics, applicable regulations, hazard potential, quantities and concentrations of materials released, the extent and use of local water resources, and specific local public interest and concerns

    1999-01-01

    Lawrence Livermore National Laboratory (LLNL) is the home of the world close-quote s highest current beam of keV positrons. The potential for establishing a national center for materials analysis using positron annihilation techniques around this capability is being actively pursued. The high LLNL beam current will enable investigations in several new areas. We are developing a positron microprobe that will produce a pulsed, focused positron beam for 3-dimensional scans of defect size and concentration with submicron resolution. Below we summarize the important design features of this microprobe. Several experimental end stations will be available that can utilize the high current beam with a time distribution determined by the electron linac pulse structure, quasi-continuous, or bunched at 20 MHz, and can operate in an electrostatic or (and) magnetostatic environment. Some of the planned early experiments are: two-dimensional angular correlation of annihilation radiation of thin films and buried interfaces, positron diffraction holography, positron induced desorption, and positron induced Auger spectroscopy. copyright 1999 American Institute of Physics

    The CUP-2 uranium ore concentrate (UOC) standard reference material, a powder, was produced at the Blind River uranium refinery of Eldorado Resources Ltd. in Canada in 1986. This material was produced as part of a joint effort by the Canadian Certified Reference Materials Project and the Canadian Uranium Producers Metallurgical Committee to develop a certified reference material for uranium concentration and the concentration of several impurity constituents. This standard was developed to satisfy the requirements of the UOC mining and milling industry, and was characterized with this purpose in mind. To produce CUP-2, approximately 25 kg of UOC derived from the Blind River uranium refinery was blended, homogenized, and assessed for homogeneity by X-ray fluorescence (XRF) analysis. The homogenized material was then packaged into bottles, containing 50 g of material each, and distributed for analysis to laboratories in 1986. The CUP-2 UOC standard was characterized by an interlaboratory analysis program involving eight member laboratories, six commercial laboratories, and three additional volunteer laboratories. Each laboratory provided five replicate results on up to 17 analytes, including total uranium concentration, and moisture content. The selection of analytical technique was left to each participating laboratory. Uranium was reported on an “as-received” basis; all other analytes (besides moisture content) were reported on a “dry-weight” basis. A bottle of 25g of CUP-2 UOC standard as described above was purchased by LLNL and characterized by the LLNL Nuclear Forensics Group. Non-destructive and destructive analytical techniques were applied to the UOC sample. Information obtained from short-term techniques such as photography, gamma spectrometry, and scanning electron microscopy were used to guide the performance of longer-term techniques such as ICP-MS. Some techniques, such as XRF and ICP-MS, provided complementary types of data. The results

    1993-01-01

    The Center for Accelerator Mass Spectrometry at LLNL has installed a new 64 position AMS sample changer on our spectrometer. This new sample changer has the capability of being controlled manually by an operator or automatically by the AMS data acquisition computer. Automatic control of the sample changer by the data acquisition system is a necessary step towards unattended AMS operation in our laboratory. The sample changer uses a fiber optic shaft encoder for rough rotational indexing of the sample wheel and a series of sequenced pneumatic cylinders for final mechanical indexing of the wheel and insertion and retraction of samples. Transit time from sample to sample varies from 4 s to 19 s, depending on distance moved. Final sample location can be set to within 50 microns on the x and y axis and within 100 microns in the z axis. Changing sample wheels on the new sample changer is also easier and faster than was possible on our previous sample changer and does not require the use of any tools

  18. Nuclear Safety Research Review Committee

    Todreas, N.E.

    1990-01-01

    The Nuclear Safety Research Review Committee has had a fundamental difficulty because of the atmosphere that has existed since it was created. It came into existence at a time of decreasing budgets. For any Committee the easiest thing is to tell the Director what additional to do. That does not really help him a lot in this atmosphere of reduced budgets which he reviewed for you on Monday. Concurrently the research arm of Nuclear Regulatory Commission has recognized that the scope of its activity needed to be increased rather than decreased. In the last two-and-a-half-year period, human factors work was reinstated, radiation and health effects investigations were reinvigorated, research in the waste area was given significant acceleration. Further, accident management came into being, and the NRC finally got back into the TMI-2 area. So with all of those activities being added to the program at the same time that the research budget was going down, the situation has become very strained. What that leads to regarding Committee membership is a need for technically competent generalists who will be able to sit as the Division Directors come in, as the contractors come in, and sort the wheat from the chaff. The Committee needs people who are interested in and have a broad perspective on what regulatory needs are and specifically how safety research activities can contribute to them. The author summarizes the history of the Committee, the current status, and plans for the future

    Under this Annex, a research program on the near-field performance assessment related to the geological disposal of radioactive waste will be carried out at the Lawrence Livermore National Laboratory (LLNL) in close collaboration with the Power Reactor and Nuclear Fuel Development Corporation of Japan (PNC). This program will focus on activities that provide direct support for PNC's near-term and long-term needs that will, in turn, utilize and further strengthen US capabilities for radioactive waste management. The work scope for two years will be designed based on the PNC's priorities for its second progress report (the H12 report) of research and development for high-level radioactive waste disposal and on the interest and capabilities of the LLNL. The work will focus on the chemical modeling for the near-field environment and long-term mechanical modeling of engineered barrier system as it evolves. Certain activities in this program will provide for a final iteration of analyses to provide additional technical basis prior to the year 2000 as determined in discussions with the PNC's technical coordinator. The work for two years will include the following activities: Activity 1: Chemical Modeling of EBS Materials Interactions--Task 1.1 Chemical Modeling of Iron Effects on Borosilicate Glass Durability; and Task 1.2 Changes in Overpack and Bentonite Properties Due to Metal, Bentonite and Water Interactions. Activity 2: Thermodynamic Database Validation and Comparison--Task 2.1 Set up EQ3/6 to Run with the Pitzer-based PNC Thermodynamic Data Base; Task 2.2 Provide Expert Consultation on the Thermodynamic Data Base; and Task 2.3 Provide Analysis of Likely Solubility Controls on Selenium. Activity 3: Engineered Barrier Performance Assessment of the Unsaturated, Oxidizing Transient--Task 3.1 Apply YMIM to PNC Transient EBS Performance; Task 3.2 Demonstrate Methods for Modeling the Return to Reducing Conditions; and Task 3.3 Evaluate the Potential for Stress Corrosion

    International Nuclear Information System (INIS)

    Homann, S.G.

    1992-01-01

    The Physics Department of the Lawrence Livermore National Laboratory (LLNL) recently constructed a Multiuser Tandem Laboratory (MTL) to perform a variety of basic and applied measurement programs. The laboratory and its research equipment were constructed with support from a consortium of LLNL Divisions, Sandia National Laboratories Livermore, and the University of California. Primary design goals for the facility were inexpensive construction and operation, high beam quality at a large number of experimental stations, and versatility in adapting to new experimental needs. To accomplish these goals, our main design decisions were to place the accelerator in an unshielded structure, to make use of reconfigured cyclotrons as effective switching magnets, and to rely on computer control systems for both radiological protection and highly reproducible and well-characterized accelerator operation. This paper addresses the radiological control computer system

  2. LLNL/YMP Waste Container Fabrication and Closure Project

    International Nuclear Information System (INIS)

    1990-10-01

    The Department of Energy's Office of Civilian Radioactive Waste Management (OCRWM) Program is studying Yucca Mountain, Nevada as a suitable site for the first US high-level nuclear waste repository. Lawrence Livermore National Laboratory (LLNL) has the responsibility for designing and developing the waste package for the permanent storage of high-level nuclear waste. This report is a summary of the technical activities for the LLNL/YMP Nuclear Waste Disposal Container Fabrication and Closure Development Project. Candidate welding closure processes were identified in the Phase 1 report. This report discusses Phase 2. Phase 2 of this effort involved laboratory studies to determine the optimum fabrication and closure processes. Because of budget limitations, LLNL narrowed the materials for evaluation in Phase 2 from the original six to four: Alloy 825, CDA 715, CDA 102 (or CDA 122) and CDA 952. Phase 2 studies focused on evaluation of candidate material in conjunction with fabrication and closure processes

    International Nuclear Information System (INIS)

    Kass, J.; Bish, W.; Copeland, A.; West, J.; Sack, S.; Myers, B.

    1991-01-01

    This report outlines the LLNL plutonium related mission anticipated over the next decade and defines the capabilities required to meet that mission wherever the Plutonium Facility is located. If plutonium work is relocated to a place where the facility is shared, then some capabilities can be commonly used by the sharing parties. However, it is essential that LLNL independently control about 20000 sq ft of net lab space, filled with LLNL controlled equipment, and staffed by LLNL employees. It is estimated that the cost to construct this facility should range from $140M to $200M. Purchase and installation of equipment to replace that already in Bldg 332 along with additional equipment identified as being needed to meet the mission for the next ten to fifteen years, is estimated to cost $118M. About $29M of the equipment could be shared. The Hardened Engineering Test Building (HETB) with its additional 8000 sq ft of unique test capability must also be replaced. The fully equipped replacement cost is estimated to be about $10M. About 40000 sq ft of setup and support space are needed along with office and related facilities for a 130 person resident staff. The setup space is estimated to cost $8M. The annual cost of a 130 person resident staff (100 programmatic and 30 facility operation) is estimated to be $20M

  11. Challenges in biotechnology at LLNL: from genes to proteins; TOPICAL

    International Nuclear Information System (INIS)

    Albala, J S

    1999-01-01

    This effort has undertaken the task of developing a link between the genomics, DNA repair and structural biology efforts within the Biology and Biotechnology Research Program at LLNL. Through the advent of the I.M.A.G.E. (Integrated Molecular Analysis of Genomes and their Expression) Consortium, a world-wide effort to catalog the largest public collection of genes, accepted and maintained within BBRP, it is now possible to systematically express the protein complement of these to further elucidate novel gene function and structure. The work has ensued in four phases, outlined as follows: (1) Gene and System selection; (2) Protein expression and purification; (3) Structural analysis; and (4) biological integration. Proteins to be expressed have been those of high programmatic interest. This includes, in particular, proteins involved in the maintenance of genome integrity, particularly those involved in the repair of DNA damage, including ERCC1, ERCC4, XRCC2, XRCC3, XRCC9, HEX1, APN1, p53, RAD51B, RAD51C, and RAD51. Full-length cDNA cognates of selected genes were isolated, and cloned into baculovirus-based expression vectors. The baculoviral expression system for protein over-expression is now well-established in the Albala laboratory. Procedures have been successfully optimized for full-length cDNA clining into expression vectors for protein expression from recombinant constructs. This includes the reagents, cell lines, techniques necessary for expression of recombinant baculoviral constructs in Spodoptera frugiperda (Sf9) cells. The laboratory has also generated a high-throughput baculoviral expression paradigm for large scale expression and purification of human recombinant proteins amenable to automation

  13. Is mandatory research ethics reviewing ethical?

    Science.gov (United States)

    Dyck, Murray; Allen, Gary

    2013-08-01

    Review boards responsible for vetting the ethical conduct of research have been criticised for their costliness, unreliability and inappropriate standards when evaluating some non-medical research, but the basic value of mandatory ethical review has not been questioned. When the standards that review boards use to evaluate research proposals are applied to review board practices, it is clear that review boards do not respect researchers or each other, lack merit and integrity, are not just and are not beneficent. The few benefits of mandatory ethical review come at a much greater, but mainly hidden, social cost. It is time that responsibility for the ethical conduct of research is clearly transferred to researchers, except possibly in that small proportion of cases where prospective research participants may be so intrinsically vulnerable that their well-being may need to be overseen.

    The Mercury Monte Carlo particle transport code developed at Lawrence Livermore National Laboratory (LLNL) is used to simulate the transport of radiation through urban environments. These challenging calculations include complicated geometries and require significant computational resources to complete. As a result, a question arises as to the level of convergence of the calculations with Monte Carlo simulation particle count. In the Trinity Open Science calculations, one main focus was to investigate convergence of the relevant simulation quantities with Monte Carlo particle count to assess the current simulation methodology. Both for this application space but also of more general applicability, we also investigated the impact of code algorithms on parallel scaling on the Trinity machine as well as the utilization of the Trinity DataWarp burst buffer technology in Mercury via the LLNL Scalable Checkpoint/Restart (SCR) library.

    1991-07-01

    This report describes main activities undertaken during the period 1 June 1990 to 1 June 1991 by MIT to support the Lawrence Livermore National Laboratory tunable FEL driver project. The goal of this research was to further characterize a tunable microwave source (already identified as a BWO-gyrotron) of moderate output power (10--20 kW). In the 1989 fiscal year, the source was assembled at MIT and initial tests were conducted. Proposed for the fiscal year 1990 were analysis of the previous experimental results, and the performance of new experiments designed to increase the voltage tuning range, the output efficiency, and magnetic field tuning. During the report period the previous experimental results were analyzed and compared to computational results and new components were designed, to make the BWO ready for further experiments. In addition, the BWO-gyrotron was mounted in a new superconducting magnet and initial magnetic field profile measurements were made

    2011-12-12

    For this task LLNL will examine the vulnerability of drinking water supplies in foothills and higher elevation areas to climate change impacts on recharge. Recharge locations and vulnerability will be determined through examination of groundwater ages and noble gas recharge temperatures in high elevation basins. LLNL will determine whether short residence times are common in one or more subalpine basin. LLNL will measure groundwater ages, recharge temperatures, hydrogen and oxygen isotopes, major anions and carbon isotope compositions on up to 60 samples from monitoring wells and production wells in these basins. In addition, a small number of carbon isotope analyses will be performed on surface water samples. The deliverable for this task will be a technical report that provides the measured data and an interpretation of the data from one or more subalpine basins. Data interpretation will: (1) Consider climate change impacts to recharge and its impact on water quality; (2) Determine primary recharge locations and their vulnerability to climate change; and (3) Delineate the most vulnerable areas and describe the likely impacts to recharge.

    International Nuclear Information System (INIS)

    Wu, C; Becker, J; Hurst, A; Stoyer, M; Cline, D; Hayes, A

    2007-01-01

    Bambino is a first generation auxiliary detector for the TIGRESS array and consists of a pair of segmented annular silicon detectors, fabricated by MicronSemiconductor Inc. Bambino provides measures of both the energy and position for outgoing charged particles and main triggers for valid events. The annular Bambino detectors are placed 3.0 cm from the target both upstream and downstream. Each detector has 24 rings in q covering angles between 20.1 o and 49.4 o and between 130.6 o to 159.9 o , with 16 sectors in φ for 2π coverage. Two sets of preamplifiers, manufactured by SwanResearch, with the sensitivity of either 5 or 50 mV/MeV are available for experiments. A special scattering chamber to accommodate this detector array was designed and fabricated in FY06 by U. of Rochester. Bambino functioned very well for the first successful TIGRESS experiment on the Coulomb excitation of radioactive 20 Na and 21 Na beams in Jul/Aug 2006. Bambino underwent a major upgrade in FY07 at a cost of about $80 k to increase the position resolution. This is achieved by doubling the number of sector to 32 and will improve the in-flight reaction product γ-ray spectroscopy resolution to about 1% or better for the TIGRESS array. This new segmented silicon detector, called CD-S3, was designed and fabricated by MicronSemiconductor Inc. CD-S3 was installed and used for the scheduled experiment E1075 in Jul/Aug 2007 (Coulomb excitation of radioactive 29 Na beam). In addition, assemble of a ΔE-E detector array for the light charged-particle identification is taking place for future experiments by acquiring detectors with thickness of both ∼140 and ∼1,000 (micro)m and associated preamplifiers

  12. Engineering research, development and technology: Thrust area report FY 91

    International Nuclear Information System (INIS)

    1991-01-01

    The mission of the Engineering Research, Development, and Technology Program at Lawrence, Livermore National Laboratory (LLNL) is to develop the technical staff and the technology needed to support current and future LLNL programs. To accomplish this mission, the Engineering Research, Development, and Technology Program has two important goals: (1) to identify key technologies and (2) conduct high quality work to enhance our capabilities in these key technologies. To help focus our efforts, we identify technology thrust areas and select technical leaders for each area. The thrust areas are integrated engineering activities and, rather than being based on individual disciplines, they are staffed by personnel from Electronics Engineering, Mechanical Engineering, and other LLNL organizations, as appropriate. The thrust area leaders are expected to establish strong links to LLNL program leaders and to industry; to use outside and inside experts to review the quality and direction of the work; to use university contacts to supplement and complement their efforts; and to be certain that we are not duplicating the work of others. The thrust area leader is also responsible for carrying out the work that follows from the Engineering Research, Development, and Technology Program so that the results can be applied as early as possible to the needs of LLNL programs. This annual report, organized by thrust area, describes activities conducted within the Program for the fiscal year, 1991. Its intent is to provide timely summaries of objectives, theories, methods, and results

  15. Participatory action research: considerations for ethical review.

    Science.gov (United States)

    Khanlou, N; Peter, E

    2005-05-01

    This paper addresses the distinctive nature of participatory action research (PAR) in relation to ethical review requirements. As a framework for conducting research and reducing health disparities, PAR is gaining increased attention in community and public health research. As a result, PAR researchers and members of Research Ethics Boards could benefit from an increased understanding of the array of ethical concerns that can arise. We discuss these concerns in light of commonly held ethical requirements for clinical research (social or scientific value, scientific validity, fair subject/participant selection, favourable risk-benefit ratio, independent review, informed consent, and respect for potential and enrolled participants) and refer to guidelines specifically developed for participatory research in health promotion. We draw from our community-based experiences in mental health promotion research with immigrant and culturally diverse youth to illustrate the ethical advantages and challenges of applying a PAR approach. We conclude with process suggestions for Research Ethics Boards.

  18. Description and application of the AERIN Code at LLNL

    International Nuclear Information System (INIS)

    King, W.C.

    1986-01-01

    The AERIN code was written at the Lawrence Livermore National Laboratory in 1976 to compute the organ burdens and absorbed dose resulting from a chronic or acute inhalation of transuranic isotopes. The code was revised in 1982 to reflect the concepts of ICRP-30. This paper will describe the AERIN code and how it has been used at LLNL to study more than 80 cases of internal deposition and obtain estimates of internal dose. A comparison with the computed values of the committed organ dose is made with ICRP-30 values. The benefits of using the code are described. 3 refs., 3 figs., 6 tabs

    1995-01-01

    In this report, we summarize recent work at LLNL on the compact torus (CT) acceleration project. The CT accelerator is a novel technique for projecting plasmas to high velocities and reaching high energy density states. The accelerator exploits magnetic confinement in the CT to stably transport plasma over large distances and to directed kinetic energies large in comparison with the CT internal and magnetic energy. Applications range from heating and fueling magnetic fusion devices, generation of intense pulses of x-rays or neutrons for weapons effects and high energy-density fusion concepts

  20. Review on Ruminant Nutrition Research

    Directory of Open Access Journals (Sweden)

    Budi Haryanto

    2012-12-01

    Full Text Available Research works in ruminant nutrition have been widely published, especially those related to the energy and protein utilization. The energy and protein requirements for maintenance and production in tropical regions may be different from those in the subtropical areas. Responses of different species of ruminants to energy and protein supplements were also observed. The synchronization of energy and protein availability has been considered as an important strategy in affecting the microbial fermentative process in the rumen and in affecting the animal performance. The inclusion of long-chained unsaturated fatty acids in the diets has been successfully affecting milk production with higher concentration of unsaturated fatty acids. Feedstuffs characteristics in terms of their degradability and fermentation by rumen microbial enzymes have been intensively studied; however, further experimentations are still needed to elucidate the specific fate of its nutritive components in the rumen and tissue levels.

  5. Urban metabolism: A review of research methodologies

    International Nuclear Information System (INIS)

    Zhang, Yan

    2013-01-01

    Urban metabolism analysis has become an important tool for the study of urban ecosystems. The problems of large metabolic throughput, low metabolic efficiency, and disordered metabolic processes are a major cause of unhealthy urban systems. In this paper, I summarize the international research on urban metabolism, and describe the progress that has been made in terms of research methodologies. I also review the methods used in accounting for and evaluating material and energy flows in urban metabolic processes, simulation of these flows using a network model, and practical applications of these methods. Based on this review of the literature, I propose directions for future research, and particularly the need to study the urban carbon metabolism because of the modern context of global climate change. Moreover, I recommend more research on the optimal regulation of urban metabolic systems. Highlights: •Urban metabolic processes can be analyzed by regarding cities as superorganisms. •Urban metabolism methods include accounting, assessment, modeling, and regulation. •Research methodologies have improved greatly since this field began in 1965. •Future research should focus on carbon metabolism and optimal regulation. -- The author reviews research progress in the field of urban metabolism, and based on her literature review, proposes directions for future research

  6. A Novel Approach to Semantic and Coreference Annotation at LLNL

    Energy Technology Data Exchange (ETDEWEB)

    Firpo, M

    2005-02-04

    A case is made for the importance of high quality semantic and coreference annotation. The challenges of providing such annotation are described. Asperger's Syndrome is introduced, and the connections are drawn between the needs of text annotation and the abilities of persons with Asperger's Syndrome to meet those needs. Finally, a pilot program is recommended wherein semantic annotation is performed by people with Asperger's Syndrome. The primary points embodied in this paper are as follows: (1) Document annotation is essential to the Natural Language Processing (NLP) projects at Lawrence Livermore National Laboratory (LLNL); (2) LLNL does not currently have a system in place to meet its need for text annotation; (3) Text annotation is challenging for a variety of reasons, many related to its very rote nature; (4) Persons with Asperger's Syndrome are particularly skilled at rote verbal tasks, and behavioral experts agree that they would excel at text annotation; and (6) A pilot study is recommend in which two to three people with Asperger's Syndrome annotate documents and then the quality and throughput of their work is evaluated relative to that of their neuro-typical peers.

  9. A review of schizophrenia research in malaysia.

    Science.gov (United States)

    Chee, K Y; Salina, A A

    2014-08-01

    Research in schizophrenia has advanced tremendously. One hundred and seventy five articles related to Schizophrenia were found from a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. This project aims to examine published research articles, in local and international journals in order to provide a glimpse of the research interest in Malaysia with regards to schizophrenia. Single case study, case series report, reviews and registry reports were not included in this review. Medication trial, unless it concerned a wider scope of psychopharmacology was also excluded from this review. A total of 105 articles were included in this review. Despite numerous genetics studies conducted and published, a definitive conclusion on the aetiology or mechanism underlying schizophrenia remains elusive. The National Mental Health - Schizophrenia Registry (NMHR) proved to be an important platform for many studies and publications. Studies stemmed from NMHR have provided significant insight into the baseline characteristic of patients with schizophrenia, pathway to care, and outcomes of the illness. International and regional collaborations have also encouraged important work involving stigma and discrimination in schizophrenia. Ministry of Health's hospitals (MOH) are the main research sites in the country with regards to schizophrenia research. Numbers of schizophrenia research are still low in relation to the number of universities and hospitals in the country. Some of the weaknesses include duplication of studies, over-emphasising clinical trials and ignoring basic clinical research, and the lack of publications in international and regional journals.

  10. Tourism and environmental research: a review

    Energy Technology Data Exchange (ETDEWEB)

    Pearce, D G

    1985-01-01

    This paper reviews the nature and scope of research into the environmental impact of tourism, the role such research may play in tourist development and conservation and the constraints which may be encountered. Research in this field is characterized by a wide spectrum of generally complex interrelationships and impacts. In recent years there has been a growing call from policy-makers for environmental guidelines, indicators and other research but as yet a few immediate solutions to their problems and answers to their request are to hand. The complexity of the issues involved and other difficulties have also limited the extent to which research has been fed into the decision-making process.

  11. Quantitative Communication Research: Review, Trends, and Critique

    Directory of Open Access Journals (Sweden)

    Timothy R. Levine

    2013-01-01

    Full Text Available Trends in quantitative communication research are reviewed. A content analysis of 48 articles reporting original communication research published in 1988-1991 and 2008-2011 is reported. Survey research and self-report measurement remain common approaches to research. Null hypothesis significance testing remains the dominant approach to statistical analysis. Reporting the shapes of distributions, estimates of statistical power, and confidence intervals remain uncommon. Trends over time include the increased popularity of health communication and computer mediated communication as topics of research, and increased attention to mediator and moderator variables. The implications of these practices for scientific progress are critically discussed, and suggestions for the future are provided.

  13. Re-Viewing Literature in Hermeneutic Research

    Directory of Open Access Journals (Sweden)

    Elizabeth Smythe PhD, RN, RM

    2012-02-01

    Full Text Available In academia there seems to be a taken for granted assumption that there is one way to do a literature review. This paper argues that the manner of reviewing literature needs to be congruent with the particular research methodology. As an example, the authors explicate reviewing literature in hermeneutic research. The paper begins by discussing philosophical assumptions. The authors then offer personal accounts of their experiences of working with literature in ways that are congruent with hermeneutic methodology. It is argued that the key purpose of exploring literature in hermeneutic research is to provide context and provoke thinking. Literature, which can include anything that provokes thinking on the phenomenon of interest, becomes an essential dialogical partner from which scholarly thinking and new insights emerge. In conclusion distinguishing hallmarks of ways of working hermeneutically with literature are articulated

    1987-06-01

    The liquid-vapor coexistence boundary is not well known for most metals because the extreme conditions near the critical point create severe experimental difficulties. The isentropes passing through the liquid-vapor region typically begin from rather large pressures on the Hugoniot. We are attempting to use the high velocities achievable with the Lawrence Livermore National Laboratory (LLNL) electric gun to obtain these extreme states in aluminum and measure the release isentropes by releasing into a series of calibrated standards with known Hugoniots. To achieve large pressure drops needed to explore the liquid-vapor region, we use argon gas for which Hugoniots have been calculated using the ACTEX code, as one of the release materials.

    2016-10-01

    There is a need for additional strategies for performing systematic reviews (SRs) to improve translation of findings into practice and to influence health policy. SRs critically appraise research methodology and determine level of evidence of research findings. The standard type of SR identifies randomized controlled trials (RCTs) as providing the most valid data and highest level of evidence. RCTs are not among the most frequently used research design in disability and health research. RCTs usually measure impairments for the primary research outcome rather than improved function, participation or societal integration. It forces a choice between "validity" and "utility/relevance." Other approaches have effectively been used to assess the validity of alternative research designs, whose outcomes focus on function and patient-reported outcomes. We propose that utilizing existing evaluation tools that measure knowledge, dissemination and utility of findings, may help improve the translation of findings into practice and health policy.

  18. Results of LLNL investigation of NYCT data sets

    International Nuclear Information System (INIS)

    Sale, K; Harrison, M; Guo, M; Groza, M

    2007-01-01

    Upon examination we have concluded that none of the alarms indicate the presence of a real threat. A brief history and results from our examination of the NYCT ASP occupancy data sets dated from 2007-05-14 19:11:07 to 2007-06-20 15:46:15 are presented in this letter report. When the ASP data collection campaign at NYCT was completed, rather than being shut down, the Canberra ASP annunciator box was unplugged leaving the data acquisition system running. By the time it was discovered that the ASP was still acquiring data about 15,000 occupancies had been recorded. Among these were about 500 alarms (classified by the ASP analysis system as either Threat Alarms or Suspect Alarms). At your request, these alarms have been investigated. Our conclusion is that none of the alarm data sets indicate the presence of a real threat (within statistics). The data sets (ICD1 and ICD2 files with concurrent JPEG pictures) were delivered to LLNL on a removable hard drive labeled FOUO. The contents of the data disk amounted to 53.39 GB of data requiring over two days for the standard LLNL virus checking software to scan before work could really get started. Our first step was to walk through the directory structure of the disk and create a database of occupancies. For each occupancy, the database was populated with the occupancy date and time, occupancy number, file path to the ICD1 data and the alarm ('No Alarm', 'Suspect Alarm' or 'Threat Alarm') from the ICD2 file along with some other incidental data. In an attempt to get a global understanding of what was going on, we investigated the occupancy information. The occupancy date/time and alarm type were binned into one-hour counts. These data are shown in Figures 1 and 2

  19. Measuring inconsistency in research ethics committee review.

    Science.gov (United States)

    Trace, Samantha; Kolstoe, Simon Erik

    2017-11-28

    The review of human participant research by Research Ethics Committees (RECs) or Institutional Review Boards (IRBs) is a complex multi-faceted process that cannot be reduced to an algorithm. However, this does not give RECs/ IRBs permission to be inconsistent in their specific requirements to researchers or in their final opinions. In England the Health Research Authority (HRA) coordinates 67 committees, and has adopted a consistency improvement plan including a process called "Shared Ethical Debate" (ShED) where multiple committees review the same project. Committee reviews are compared for consistency by analysing the resulting minutes. We present a description of the ShED process. We report an analysis of minutes created by research ethics committees participating in two ShED exercises, and compare them to minutes produced in a published "mystery shopper" exercise. We propose a consistency score by defining top themes for each exercise, and calculating the ratio between top themes and total themes identified by each committee for each ShED exercise. Our analysis highlights qualitative differences between the ShED 19, ShED 20 and "mystery shopper" exercises. The quantitative measure of consistency showed only one committee across the three exercises with more than half its total themes as top themes (ratio of 0.6). The average consistency scores for the three exercises were 0.23 (ShED19), 0.35 (ShED20) and 0.32 (mystery shopper). There is a statistically significant difference between the ShED 19 exercise, and the ShED 20 and mystery shopper exercises. ShED exercises are effective in identifying inconsistency between ethics committees and we describe a scoring method that could be used to quantify this. However, whilst a level of inconsistency is probably inevitable in research ethics committee reviews, studies must move beyond the ShED methodology to understand why inconsistency occurs, and what an acceptable level of inconsistency might be.

  20. Research Review: Death Online - Alive and Kicking!

    2014-01-01

    In recent years, the physical death, the related grief, and the ensuing memorials has become visible in the digital arena. As every other aspect of life is to be found online, so are death and the surrounding issues. The research into the area is not far behind, and using the approach of a timeline...... with different stakeholders, this research review offers a systematic way of keeping track. The rather simple timeline relates to the death of a person, there is before, just around, and after death, appropriately named in a dead language: Ante Mortem, Peri Mortem, and Post Mortem. This review deals exclusively...... with the digital context of the physical death of existing human beings, as opposed to, e.g., in-game death experience or memorials for fictional characters. These are no doubt interesting issues that deserve their own review, although we might need to put citation marks around "death"....

  4. Narrative research in psychotherapy: a critical review.

    Science.gov (United States)

    Avdi, Evrinomy; Georgaca, Eugenie

    2007-09-01

    This paper is a review of studies which utilise the notion of narrative to analyse psychotherapy. Its purpose is to systematically present this diverse field of research, to highlight common themes and divergences between different strands and to further the development and integration of narrative research in psychotherapy. The paper reviews studies which employ an applied textual analysis of narratives produced in the context of psychotherapy. Criteria for inclusion of studies are, firstly, the analysis of therapeutic and therapy-related texts and, secondly, the adoption of a narrative psychological perspective. The studies were examined on the basis of the notion of narrative they employ and the aspects of client narratives they focus on, and were grouped accordingly in the review. The majority of the studies reviewed assume a constructivist approach to narrative, adopt a representational view of language, focus primarily on client micro-narratives and relate to cognitive-constructivist and process-experiential psychotherapeutic approaches. A smaller group of studies assume a social constructionist approach to narrative and a functional view of language, focus on micro-narratives, highlight the interactional and wider social aspects of narrative and relate to postmodern trends in psychotherapy. The range of conceptualisations of narrative in the studies reviewed, from a representational psychological view to a constructionist social view, reflects tensions within narrative psychology itself. Moreover, two trends can be discerned in the field reviewed, narrative analysis of therapy, which draws from narrative theory and utilises the analytic approaches of narrative research to study psychotherapy, and analyses of narrative in therapy, which study client narratives using non-narrative qualitative methods. Finally, the paper highlights the need for integration of this diverse field of research and urges for the development of narrative studies of psychotherapy

  7. Grounded theory research: literature reviewing and reflexivity.

    Science.gov (United States)

    McGhee, Gerry; Marland, Glenn R; Atkinson, Jacqueline

    2007-11-01

    This paper is a report of a discussion of the arguments surrounding the role of the initial literature review in grounded theory. Researchers new to grounded theory may find themselves confused about the literature review, something we ourselves experienced, pointing to the need for clarity about use of the literature in grounded theory to help guide others about to embark on similar research journeys. The arguments for and against the use of a substantial topic-related initial literature review in a grounded theory study are discussed, giving examples from our own studies. The use of theoretically sampled literature and the necessity for reflexivity are also discussed. Reflexivity is viewed as the explicit quest to limit researcher effects on the data by awareness of self, something seen as integral both to the process of data collection and the constant comparison method essential to grounded theory. A researcher who is close to the field may already be theoretically sensitized and familiar with the literature on the study topic. Use of literature or any other preknowledge should not prevent a grounded theory arising from the inductive-deductive interplay which is at the heart of this method. Reflexivity is needed to prevent prior knowledge distorting the researcher's perceptions of the data.

    Background To date there is no established consensus of assessment criteria for evaluating research ethics review. Methods We conducted a scoping review of empirical research assessing ethics review processes in order to identify common elements assessed, research foci, and research gaps to aid in the development of assessment criteria. Electronic searches of Ovid Medline, PsychInfo, and the Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA, and NHSEED, were conducted. After de-duplication, 4234 titles and abstracts were reviewed. Altogether 4036 articles were excluded following screening of titles, abstracts and full text. A total of 198 articles included for final data extraction. Results Few studies originated from outside North America and Europe. No study reported using an underlying theory or framework of quality/effectiveness to guide study design or analyses. We did not identify any studies that had involved a controlled trial - randomised or otherwise – of ethics review procedures or processes. Studies varied substantially with respect to outcomes assessed, although tended to focus on structure and timeliness of ethics review. Discussion Our findings indicate a lack of consensus on appropriate assessment criteria, exemplified by the varied study outcomes identified, but also a fragmented body of research. To date research has been largely quantitative, with little attention given to stakeholder experiences, and is largely cross sectional. A lack of longitudinal research to date precludes analyses of change or assessment of quality improvement in ethics review. PMID:26225553

  12. Public Attitudes toward Animal Research: A Review

    Directory of Open Access Journals (Sweden)

    Elisabeth H. Ormandy

    2014-06-01

    Full Text Available The exploration of public attitudes toward animal research is important given recent developments in animal research (e.g., increasing creation and use of genetically modified animals, and plans for progress in areas such as personalized medicine, and the shifting relationship between science and society (i.e., a move toward the democratization of science. As such, public engagement on issues related to animal research, including exploration of public attitudes, provides a means of achieving socially acceptable scientific practice and oversight through an understanding of societal values and concerns. Numerous studies have been conducted to explore public attitudes toward animal use, and more specifically the use of animals in research. This paper reviews relevant literature using three categories of influential factors: personal and cultural characteristics, animal characteristics, and research characteristics. A critique is given of survey style methods used to collect data on public attitudes, and recommendations are given on how best to address current gaps in public attitudes literature.

    Full Text Available Water resources, particularly in arid and semi-arid regions of the world are of great concern, as they are closely linked to the wellbeing of humankind. Sophisticated hydrological prediction tools are required to assess climatic and hydrometeorological conditions, as they impact the sustainability of water resources as well as water availability. Research and data collection activities from multi-hydrometeorological sensors (e.g., gauges, radars, satellites form the basis for quantifying the impact of extreme episodes along the hydrologic phases that manifest in terms of the magnitude, duration and frequency of floods, droughts and other hydrometeorological hazards that affect water resources management. A number of hydrometeorological research activities have been reported in the literature by various researchers and research groups globally. This contribution presents (a a review of the hydrometeorology resource landscape in South Africa; (b an analysis of the hydrometeorology services and products in South Africa; (c a review of the hydrometeorological research that has been conducted in South Africa for the last four decades; and (d highlights on some of the challenges facing the sustained advancement of research in hydrometeorology in South Africa.

    2016-06-01

    Research on the efficacy of yoga for improving mental, emotional, physical, and behavioral health characteristics in school settings is a recent but growing field of inquiry. This systematic review of research on school-based yoga interventions published in peer-reviewed journals offers a bibliometric analysis that identified 47 publications. The studies from these publications have been conducted primarily in the United States (n = 30) and India (n = 15) since 2005, with the majority of studies (n = 41) conducted from 2010 onward. About half of the publications were of studies at elementary schools; most (85%) were conducted within the school curriculum, and most (62%) also implemented a formal school-based yoga program. There was a high degree of variability in yoga intervention characteristics, including overall duration, and the number and duration of sessions. Most of these published research trials are preliminary in nature, with numerous study design limitations, including limited sample sizes (median = 74; range = 20-660) and relatively weak research designs (57% randomized controlled trials, 19% uncontrolled trials), as would be expected in an infant research field. Nevertheless, these publications suggest that yoga in the school setting is a viable and potentially efficacious strategy for improving child and adolescent health and therefore worthy of continued research. © 2016 New York Academy of Sciences.

    1999-01-01

    In 1984, Congress and the Department of Energy (DOE) established the Laboratory Directed Research and Development (LDRD) Program to enable the director of a national laboratory to foster and expedite innovative research and development (R and D) in mission areas. The Lawrence Livermore National Laboratory (LLNL) continually examines these mission areas through strategic planning and shapes the LDRD Program to meet its long-term vision. The goal of the LDRD Program is to spur development of new scientific and technical capabilities that enable LLNL to respond to the challenges within its evolving mission areas. In addition, the LDRD Program provides LLNL with the flexibility to nurture and enrich essential scientific and technical competencies and enables the Laboratory to attract the most qualified scientists and engineers. The FY98 LDRD portfolio described in this annual report has been carefully structured to continue the tradition of vigorously supporting DOE and LLNL strategic vision and evolving mission areas. The projects selected for LDRD funding undergo stringent review and selection processes, which emphasize strategic relevance and require technical peer reviews of proposals by external and internal experts. These FY98 projects emphasize the Laboratory's national security needs: stewardship of the U.S. nuclear weapons stockpile, responsibility for the counter- and nonproliferation of weapons of mass destruction, development of high-performance computing, and support of DOE environmental research and waste management programs

    The literature including a number of review articles was examined for answers to the questions, have distinctive personality test profiles of pathological gamblers been identified, do pathological gamblers have control over their behavior, have studies of alcoholism and addiction increased understanding of compulsive gambling, and has psychotherapy or Gamblers Anonymous been successful for them? Much more information is needed to build on what research on these questions has yielded.

    2012-01-01

    I attended the 20th biannual International Conference on Plasma Surface Interaction (PSI) in Fusion Devices in Aachen, Germany, hosted this year by the Forschungszentrum Julich (FZJ) research center. The PSI conference is one of the main international forums for the presentation and discussion of results on plasma surface interactions and edge plasma physics relevant to magnetic confinement fusion devices. I disseminated the recent results of FESP/LLNL tokamak research by presenting three posters on: (i) understanding reconnection and controlling edge localized modes (ELMs) using the BOUT++ code, (ii) simulation of resistive ballooning mode turbulence, and (iii) innovative design of Snowflake divertors. I learned of many new and recent results from international tokamak facilities and had the opportunity for discussion of these topics with other scientists at the poster sessions, conference lunches/receptions, etc. Some of the major highlights of the PSI conference topics were: (1) Review of the progress in using metallic tungsten and beryllium (ITER-like) walls at international tokamak facilities: JET (Culham, UK), TEXTOR (FZJ, Germany) and Alcator CMOD (MIT, USA). Results included: effect of small and large-area melting on plasma impurity content and recovery, expected reduction in retention of hydrogenic species, increased heat load during disruptions and need for mitigation with massive gas injection. (2) A review of ELM control in general (T. Evans, GA) and recent results of ELM control using n=2 external magnetic perturbations on ASDEX-Upgrade (MPI-Garching, Germany). (3) General agreement among the international tokamak database that, along the outer midplane of a low collisionality tokamak, the SOL power width in current experiments varies inversely with respect to plasma current (Ip), roughly as 1/Ip, with little dependence on other plasma parameters. This would imply roughly a factor of 1/4 of the width that was assumed for the design of the ITER tokamak

    The difficulties of a comprehensive review of the broad and diverse branches of molecular and solid-state luminescence research are noted. This review is thus limited to selective topics. Some general concepts and trends are then introduced, including: luminescence excitation as a collective excitation of a many-body problem, encompassing in some cases the source and probe in its formulation; continuing trends towards extremal conditions of experiments and towards inhomogeneous and structured materials, from man-made superlattices to biological materials; and increased attention to applications of luminescence research to lamps, displays, solar devices and biological research. Representative recent and new specific research areas include: site selection spectroscopy and 'hole burning'; picosecond delayed coherent anti-Stokes Raman scattering; computer simulation of dynamical processes in luminescence; electron-hole expansion from the Fermi pressure of e-h plasmas; and hot electron phenomena and hot luminescence. Finally some pending problems in luminescence research, such as reconciling the configuration coordinate model and the electronic band theory and clarifying multi-phonon non-radiative processes, are discussed.

    Using x-ray computerized tomography (CT), we have characterized the x-ray linear attenuation coefficients (LAC) of a homemade Play Dough{trademark}-like material, designated as PDA. Table 1 gives the first-order statistics for each of four CT measurements, estimated with a Gaussian kernel density estimator (KDE) analysis. The mean values of the LAC range from a high of about 2700 LMHU{sub D} 100kVp to a low of about 1200 LMHUD at 300kVp. The standard deviation of each measurement is around 10% to 15% of the mean. The entropy covers the range from 6.0 to 7.4. Ordinarily, we would model the LAC of the material and compare the modeled values to the measured values. In this case, however, we did not have the detailed chemical composition of the material and therefore did not model the LAC. Using a method recently proposed by Lawrence Livermore National Laboratory (LLNL), we estimate the value of the effective atomic number, Z{sub eff}, to be near 10. LLNL prepared about 50mL of the homemade 'Play Dough' in a polypropylene vial and firmly compressed it immediately prior to the x-ray measurements. We used the computer program IMGREC to reconstruct the CT images. The values of the key parameters used in the data capture and image reconstruction are given in this report. Additional details may be found in the experimental SOP and a separate document. To characterize the statistical distribution of LAC values in each CT image, we first isolated an 80% central-core segment of volume elements ('voxels') lying completely within the specimen, away from the walls of the polypropylene vial. All of the voxels within this central core, including those comprised of voids and inclusions, are included in the statistics. We then calculated the mean value, standard deviation and entropy for (a) the four image segments and for (b) their digital gradient images. (A digital gradient image of a given image was obtained by taking the absolute value of the difference

  5. Tire Crumb Research Study Literature Review / Gap ...

    Science.gov (United States)

    In order to more fully understand data gaps in human exposure and toxicity to tire crumb materials, ATSDR, CPSC and EPA undertook a collaborative effort in the form of a scientific literature review and subsequent gaps analysis. The first objective of the Literature Review and Gap Analysis (LRGA) collaboration was to identify the existing body of literature related specifically to human exposure to tire crumb materials through the use of synthetic turf athletic fields and playgrounds. The second objective was to characterize and summarize the relevant data from the scientific literature. The final objective was to review the summary information and identify data gaps to build on the current understanding of the state-of-the-science and inform the development of specific research efforts that would be most impactful in the near-term. Because of the need for additional information, the U.S. Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (ATSDR), and the U.S. Consumer Product Safety Commission (CPSC) launched a multi-agency action plan to study key environmental human health questions. The Federal Research Action Plan includes numerous activities, including research studies (U.S. EPA, 2016). A key objective of the Action Plan is to identify key knowledge gaps.

    The authors have completed the initial phase of a 250 GHz CARM experiment, driven by the 2 MeV, 1 kA, 30 ns induction linac at the LLNL ARC facility. A non-Brillouin, solid, electron beam is generated from a flux-threaded, thermionic cathode. As the beam traverses a 10 kG plateau produced by a superconducting magnet, ten percent of the beam energy is converted into rotational energy in a bifilar helix wiggler that produces a spiraling, 50 G, transverse magnetic field. The beam is then compressed to a 5 mm diameter as it drifts into a 30 kG plateau. For the present experiment, the CARM interaction region consisted of a single Bragg section resonator, followed by a smooth-bore amplifier section. Using high-pass filters, they have observed broadband output signals estimated to be at the several megawatt level in the range 140 to over 230 GHz. This is consistent with operation as a superradiant amplifier. Simultaneously, they also observed K a band power levels near 3 MW

    The following position paper will describe DOE-STD-3013 container sets No.L000072 and No.L000076, and how they are compliant with DOE-STD-3013-2004. All masses of accountable nuclear materials are measured on LLNL certified balances maintained under an MC and A Program approved by DOE/NNSA LSO. All accountability balances are recalibrated annually and checked to be within calibration on each day that the balance is used for accountability purposes. A statistical analysis of the historical calibration checks from the last seven years indicates that the full-range Limit of Error (LoE, 95% confidence level) for the balance used to measure the mass of the contents of the above indicated 3013 containers is 0.185 g. If this error envelope, at the 95% confidence level, were to be used to generate an upper-limit to the measured weight of the containers No.L000072 and No.L000076, the error-envelope would extend beyond the 5.0 kg 3013-standard limit on the package contents by less than 0.3 g. However, this is still well within the intended safety bounds of DOE-STD-3013-2004

    The role of the Research Program in Controlled Thermonuclear Research, the activities that are contained within the Research Program, and summaries of the reports prepared by the study groups that analyzed the six activity areas that make up the Research Program are described. The recommendations by an ''Overview Panel'' are given. The recommendations are based on an analysis of the individual study group reports, consultations with CTR staff and field scientists, and on independent review of CTR program plans and needs. In some cases the recommendations of the Overview Panel are identical with study group recommendations and in other cases they are not. Some recommendations by the Overview Panel take into account factors and information that go beyond that available to the study groups. The five-year budget needed to accomplish the recommended Research Program is discussed. The Overview Panel chose to normalize its budget recommendations to the actual FY 1975 Research Program budget, reflecting the fact that this is already determined. The budgets for subsequent years are then based on this starting point. The complete reports prepared by the six study groups are given. Each report is based on an analysis of the needs as dictated by the Magnetic Confinement Systems and Development and Technology Program Plans. (U.S.)

  11. Review of research methodologies for tigers: telemetry.

    Miller, Clayton S; Hebblewhite, Mark; Goodrich, John M; Miquelle, Dale G

    2010-12-01

    Over the past half century, wildlife research has relied on technological advances to gain additional insight into the secretive lives of animals. This revolution started in the 1960s with the development of radio telemetry and continues today with the use of Global Positioning System (GPS)-based research techniques. In the present paper we review the history of radio telemetry from its origins with grizzly bears in Yellowstone to its early applications in tiger research and conservation in Asia. We address the different types of data that are available using radio telemetry as opposed to using other research techniques, such as behavioral observations, camera trapping, DNA analysis and scat analysis. In the late 1990s, the rapid development of GPS collar technology revolutionized wildlife research. This new technology has enabled researchers to dramatically improve their ability to gather data on animal movements and ecology. Despite the ecological and conservation benefits of radio telemetry, there have been few telemetry studies of tigers in the wild, and most have been on the Bengal or Amur subspecies. We close with an assessment of the current tiger conservation efforts using GPS technology and discuss how this new information can help to preserve tigers for future generations. © 2010 ISZS, Blackwell Publishing and IOZ/CAS.

    Display research has comprised a substantial portion of the defense investment in new technology for national security for the past 13 years. These investments have been made by the separate service departments and, especially, via several Defense Research Projects Agency (DARPA) programs, known collectively as the High Definition Systems (HDS) Program (which ended in 2001) and via the Office of the Secretary of Defense (OSD) Defense Production Act (DPA) Title III Program (efforts ended in 2000). Using input from the Army, Navy, and Air Force to focus research and identify insertion opportunities, DARPA and the Title III Program Office have made investments to develop the national technology base and manufacturing infrastructure necessary to meet the twin challenge of providing affordable displays in current systems and enabling the DoD strategy of winning future conflicts by getting more information to all participants during the battle. These completed DARPA and DPA research and infrastructure programs are reviewed. Service investments have been and are being made to transition display technology; examples are described. Display science and technology (S&T) visions are documented for each service to assist the identification of areas meriting consideration for future defense research.

    The LLNL work smart standard requires us to provide ongoing laser safety training for a large number of persons on a three-year cycle. In order to meet the standard, it was necessary to find a cost and performance effective method to perform this training. This paper discusses the scope of the training problem, specific LLNL training needs, various training methods used at LLNL, the advantages and disadvantages of these methods and the rationale for selecting web-based laser safety training. The tools and costs involved in developing web-based training courses are also discussed, in addition to conclusions drawn from our training operating experience. The ILSC lecture presentation contains a short demonstration of the LLNL web-based laser safety-training course.

    The AMS measurement program at LLNL began in earnest in late 1989, and has initially concentrated on 14 C measurements for biomedical and geoscience applications. We have now begun measurements on 10 Be and 36 Cl, are presently testing the spectrometer performance for 26 Al and 3 H, and will begin tests on 7 Be, 41 Ca and 129 I within the next few months. Our laboratory has a strong biomedical AMS program of 14 C tracer measurements involving large numbers of samples (sometimes hundreds in a single experiment) at 14 C concentrations which are typically .5--5 times Modern, but are occasionally highly enriched. The sample preparation techniques required for high throughput and low cross-contamination for this work are discussed elsewhere. Similar demands are placed on the AMS measurement system, and in particular on the ion source. Modifications to our GIC 846 ion source, described below, allow us to run biomedical and geoscience or archaeological samples in the same source wheel with no adverse effects. The source has a capacity for 60 samples (about 45 unknown) in a single wheel and provides currents of 30--60μA of C - from hydrogen-reduced graphite. These currents and sample capacity provide high throughput for both biomedical and other measurements: the AMS system can be started up, tuned, and a wheel of carbon samples measured to 1--1.5% in under a day; and 2 biomedical wheels can be measured per day without difficulty. We report on the present status of the Lawrence Livermore AMS spectrometer, including sample throughput and progress towards routine 1% measurement capability for 14 C, first results on other isotopes, and experience with a multi-sample high intensity ion source. 5 refs

    Full Text Available I have participated in writing ethical approval applications for research projects in Sweden a dozen times. I am also since some years a member of the local ethics advisory board in a mostly rural area serving 180.000 people. From that position I advise on what types of local project applications will have to be sent further to the regional ethics committee, REPN in Sweden. With that background I will try to give a brief Swedish perspective on research ethics reviews in general and regarding CGT (classic grounded theory studies using qualitative data in particular.The most famous Swedish example of unethical research is the 1947-1951 Vipeholm sugar trial (Krasse, 2001. Several hundred intellectually and mentally challenged persons at the Vipeholm institution were for years given an excess amount of sugar, mostly in the shape of candy. This resulted in caries that totally ruined the teeth of 50 persons. Of course participants did not give informed consent. Yet, at the time the research was not considered unethical. At least there was no debate about it.

  3. Impact of the Revised 10 CFR 835 on the Neutron Dose Rates at LLNL

    International Nuclear Information System (INIS)

    Radev, R.

    2009-01-01

    In June 2007, 10 CFR 835 (1) was revised to include new radiation weighting factors for neutrons, updated dosimetric models, and dose terms consistent with the newer ICRP recommendations. A significant aspect of the revised 10 CFR 835 is the adoption of the recommendations outlined in ICRP-60 (2). The recommended new quantities demand a review of much of the basic data used in protection against exposure to sources of ionizing radiation. The International Commission on Radiation Units and Measurements has defined a number of quantities for use in personnel and area monitoring (3,4,5) including the ambient dose equivalent H*(d) to be used for area monitoring and instrument calibrations. These quantities are used in ICRP-60 and ICRP-74. This report deals only with the changes in the ambient dose equivalent and ambient dose rate equivalent for neutrons as a result of the implementation of the revised 10 CFR 835. In the report, the terms neutron dose and neutron dose rate will be used for convenience for ambient neutron dose and ambient neutron dose rate unless otherwise stated. This report provides a qualitative and quantitative estimate of how much the neutron dose rates at LLNL will change with the implementation of the revised 10 CFR 835. Neutron spectra and dose rates from selected locations at the LLNL were measured with a high resolution spectroscopic neutron dose rate system (ROSPEC) as well as with a standard neutron rem meter (a.k.a., a remball). The spectra obtained at these locations compare well with the spectra from the Radiation Calibration Laboratory's (RCL) bare californium source that is currently used to calibrate neutron dose rate instruments. The measurements obtained from the high resolution neutron spectrometer and dose meter ROSPEC and the NRD dose meter compare within the range of ±25%. When the new radiation weighting factors are adopted with the implementation of the revised 10 CFR 835, the measured dose rates will increase by up to 22%. The

    Full Text Available Abstract To date, almost one and a half million cases of cancer are diagnosed every year in the US and nearly 560,000 Americans are expected to die of cancer in the current year, more than 1,500 people a day (data from the American Cancer Society at http://www.cancer.org/. According to the World Health Organization (WHO, roughly 20% of all cancers worldwide results from chronic infections; in particular, up to 15% of human cancers is characterized by a viral aetiology with higher incidence in Developing Countries. The link between viruses and cancer was one of the pivotal discoveries in cancer research during the past Century. Indeed, the infectious nature of specific tumors has important implications in terms of their prevention, diagnosis, and therapy. In the 21st Century, the research on viral oncology field continues to be vigorous, with new significant and original studies on viral oncogenesis and translational research from basic virology to treatment of cancer. This review will cover different viral oncology aspects, starting from the history of viral oncology and moving to the peculiar features of oncogenic RNA and DNA viruses, with a special focus on human pathogens.

    1995-10-01

    In the German HDR (Heissdampfreaktor, hot steam reactor) reactor safety programme, experiments and simulating numerical analyses have been undertaken since 1976 to study the integrity and safety of light water reactors under operational and faulted conditions. The last experiments of the programme were conducted in 1991. The post test analyses have been finished by March 1994 and the last final reports were obtained a few months later. The report aims to inform the utilities and the regulatory body of Finland about the contents of the lokset HDR research programme and to consider the applicability of the results to safety analyses of Finnish nuclear power plants. The report centers around the thermal shock and piping component experiments within the last or third phase of the HDR programme. Investigations into severe reactor accidents, fire safety and non-destructive testing, also conducted during the third phase, are not considered. The report presents a review of the following experiment groups: E21 (crack growth under corrosive conditions, loading due to thermal stratification), E22 (leak rate and leak detection experiments of through-cracked piping), E23 (thermal transient and stratification experiments for a pipe nozzle), E31 (vibration of cracked piping due to blow down and closure of isolation valve), E32 (seismically induced vibrations of cracked piping), E33 (condensation phenomena in horizontal piping during emergency cooling). A comprehensive list of reference reports, received by VTT and containing a VTT more detailed description, is given for each experiment group. The review is focused on the loading conditions and their theoretical modelling. A comparison of theoretical and experimental results is presented for each experiment group. The safety margins are finally assessed with special reference to leak-before-break, a well known principle for assuring the integrity of primary circuit piping of nuclear power plants. (orig.)

    Full Text Available Cooperative learning, where students work in small groups to accomplish shared goals, is widely recognized as a teaching strategy that promotes learning and socialization among students from kindergarten through college and across different subject domains. It has been used successfully to promote reading and writing achievements, understanding and conceptual development in science classes, problem-solving in mathematics, and higher-order thinking and learning to name just a few. It has been shown to enhance students' willingness to work cooperatively and productively with others with diverse learning and adjustment needs and to enhance intergroup relations with those from culturally and ethnically different backgrounds. It has also been used as a teaching strategy to assist students to manage conflict and to help students identified as bullies learn appropriate interpersonal skills. In fact, it has been argued that cooperative learning experiences are crucial to preventing and alleviating many of the social problems related to children, adolescents, and young adults. There is no doubt that the benefits attributed to cooperative learning are widespread and numerous and it is the apparent success of this approach to learning that has led to it being acclaimed as one of the greatest educational innovations of recent times. The purpose of this paper is not only to review developments in research on cooperative learning but also to examine the factors that mediate and moderate its success. In particular, the review focuses on the types of student and teacher interactions generated and the key role talk plays in developing student thinking and learning, albeit through the expression of contrasting opinions or constructed shared meaning. The intention is to provide additional insights on how teachers can effectively utilize this pedagogical approach to teaching and learning in their classrooms.

  11. Overview and applications of the Monte Carlo radiation transport kit at LLNL

    1999-01-01

    Modern Monte Carlo radiation transport codes can be applied to model most applications of radiation, from optical to TeV photons, from thermal neutrons to heavy ions. Simulations can include any desired level of detail in three-dimensional geometries using the right level of detail in the reaction physics. The technology areas to which we have applied these codes include medical applications, defense, safety and security programs, nuclear safeguards and industrial and research system design and control. The main reason such applications are interesting is that by using these tools substantial savings of time and effort (i.e. money) can be realized. In addition it is possible to separate out and investigate computationally effects which can not be isolated and studied in experiments. In model calculations, just as in real life, one must take care in order to get the correct answer to the right question. Advancing computing technology allows extensions of Monte Carlo applications in two directions. First, as computers become more powerful more problems can be accurately modeled. Second, as computing power becomes cheaper Monte Carlo methods become accessible more widely. An overview of the set of Monte Carlo radiation transport tools in use a LLNL will be presented along with a few examples of applications and future directions

    2016-06-01

    Two hundred and seventy one original published materials related to tobacco use were found in a search through a database dedicated to indexing all original data relevant to Medicine and Health in Malaysia from 1996 - 2015. A total of 147 papers were selected and reviewed on the basis of their relevance and implications for future research. Findings were summarised, categorised and presented according to epidemiology, behaviour, clinical features and management of smoking. Most studies are cross-sectional with small sample sizes. Studies on smoking initiation and prevalence showed mixed findings with many small scale studies within the sub-groups. The majority of the studies were related to factors that contribute to initiation in adolescents. Nonetheless, there are limited studies on intervention strategies to curb smoking among this group. There is a lack of clinical studies to analyse tobacco use and major health problems in Malaysia. In addition, studies on the best treatment modalities on the use of pharmacotherapy and behavioural counselling have also remained unexplored. Reasons why smokers do not seek clinic help to quit smoking need further exploration. A finding on the extent of effort carried out by healthcare providers in assisting smokers to make quit attempts is not known. Studies on economic and government initiatives on policies and tobacco use focus mainly on the effects of cigarette bans, increased cigarettes taxes and the influence of the tobacco industry. Recommendations are given for the government to increase efforts in implementing smoke-free legislation, early and tailored interventions. Clinical studies in this area are lacking, as are opportunities to research on ways to reduce smoking initiation age and the most effective quit smoking strategies.

    Depression is a debilitating illness and has become a leading cause of morbidity globally. We aim to summarise the evidence available in regard to the prevalence, type of assessment tools used and treatment options for depression in Malaysia. Two hundred and forty seven articles related to depression were found in a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. Fifty seven articles were selected and reviewed on the basis of clinical relevance and future research implications. Findings were summarised, categorised and presented according to prevalence of depression, depression in women, depression in clinical condition, assessment tools, and treatment of depression. The prevalence of depression in Malaysia was estimated to be between 8 and 12%. The figures were higher among women of low socio-economic background or those with comorbid medical condition. The common assessment tools used in Malaysia include Beck Depression Inventory (BDI), Depression, Anxiety and Stress Scale (DASS), Patient Health Questionnaire 9 (PHQ-9) and Hospital Anxiety and Depression Scale (HADS). They were translated into the Malay language and their psychometric properties were established. Both pharmacological treatment and psychotherapy were commonly used in Malaysia, and were highly recommended in local clinical practice guidelines. There are discrepancies in the reported rates of depression in Malaysia and this needs to be addressed. There were lack of studies looking into the depression among subgroups in Malaysia especially in the male population. There were several instruments available for assessment of depression in Malaysia but their suitability for the local setting need further research. Both pharmacotherapy and psychotherapy were recommended in the local treatment guideline in Malaysia. With the emergence of generic medication, we need to compare their clinical efficacy and tolerability

    With the continued expansion of human presence into space, typical mission durations will routinely exceed six months and extend to distances beyond the Moon. As such, sending periodic resupply vehicles, as currently provided to the International Space Station, will likely no longer be feasible. Instead, self-sustaining life support systems that recycle human waste products will become increasingly necessary, especially for planetary bases. The idea of bioregenerative life support systems using algal photobioreactors has been discussed since the beginning of the space age. In order to evaluate how such a system could be implemented, a variety of space flight studies aimed at characterizing the potential for using algae in air revitalization, water recycling, food production, and radiation shielding applications have been conducted over the years. Also, given the recent, growing interest in algal research for regenerative fuel production, food supplements, and cosmetics, many algal strains are already well documented from related terrestrial experiments. This paper reviews past algal experiments flown in space from 1960 until today. Experimental methods and results from 51 investigations utilizing either green algae (Chlorophyta), cyanobacteria (Cyanophyta), or Euglenophyta are analyzed and categorized by a variety of parameters, including size, species and duration. The collected data are summarized in a matrix that allows easy comparison between the experiments and provides important information for future life support system requirement definition and design. Similarities between experiment results are emphasized. Common problems and shortcomings are summarized and analyzed in terms of potential solutions. Finally, key research gaps, which must be closed before developing a functional life support system, are identified.

    2017-09-01

    Full Text Available We review the recent academic and policy literature on bank loan loss provisioning. Among other things, we observe that there exist some interaction between LLPs and existing prudential, accounting, institutional, cultural, religious, tax and fiscal frameworks which differ across countries; and we find that managerial discretion in provisioning is strongly linked to income smoothing, capital management, signalling, tax management and other objectives. We also address several issues including the ethical dimensions of income smoothing, factors influencing income smoothing, methodological issues in LLP modelling and the dynamic loan loss provisioning experiment; which opens up several avenues for further research such as: finding a balance between sufficient LLPs which regulators want versus transparent LLPs which standard setters want; the sensitivity of abnormal LLPs to changes in equity; the persistence of abnormal LLPs following CEO exit; country-specific interventions that induce LLP procyclicality in emerging countries; the impact of Basel III on banks' provisioning discretion; LLP behaviour among systemic and non-systemic financial institutions; etc. We conclude that regulators need to pay attention to how much discretion lending institutions should have in determining reported provision estimates, and this has been a long standing issue.

  16. Magnetic particles in medical research - a review

    International Nuclear Information System (INIS)

    Sajid, K.M.

    2001-01-01

    Magnetic (or magnetizable) particles have assumed increasing importance in medical and biological research since 1966 when the effect of a magnetic field on the movement of suspended particles was initially studied. In fields like haematology, cell biology, microbiology, biochemistry and immunoassays, they currently provide the basis for separation techniques, which previously relied on gravitational forces. The body cells (e.g., blood cells) can be made magnetic by incubating them in a medium containing several Fe/sub 3/O/sub 4/ particles, which are adsorbed to the membrane surfaces. Some bacteria (also called magnetostatic bacteria) respond to externally applied magnetic lines of force due to their intracellular magnetic particles. These properties are useful in the isolation of these cells/bacteria. In biochemistry magnetic particles are used to immobilize enzymes without any loss of enzyme activity. The immobilized enzymes can facilitate the separation of end products without extensive instrumentation. In immunoassays the antibodies are covalently linked to polymer coated iron oxide particles. An electromagnet is used to sediment these particles after reaction. This excludes the use of centrifuge to separate antigen-antibody complexes. In pharmacy and pharmacology the magnetic particles are important in drug transport. In techniques like ferrography, nuclear magnetic resonance imaging (NMRI), spectroscopic studies and magnetic resonance imaging (MRI) the magnetic particles serve as contrast agents and give clinically important spatial resolution. Magnetic particles also find extensive applications in cancer therapy, genetic engineering, pneumology, nuclear medicine, radiology and many other fields. This article reviews these applications.

    The Lawrence Livermore National Laboratory uses neutron activation elements in a Panasonic TLD holder as a personnel nuclear accident dosimeter (PNAD). The LLNL PNAD has periodically been tested using a Cf-252 neutron source, however until 2009, it was more than 25 years since the PNAD has been tested against a source of neutrons that arise from a reactor generated neutron spectrum that simulates a criticality. In October 2009, LLNL participated in an intercomparison of nuclear accident dosimeters at the CEA Valduc Silene reactor (Hickman, et.al. 2010). In September 2010, LLNL participated in a second intercomparison of nuclear accident dosimeters at CEA Valduc. The reactor generated neutron irradiations for the 2010 exercise were performed at the Caliban reactor. The Caliban results are described in this report. The procedure for measuring the nuclear accident dosimeters in the event of an accident has a solid foundation based on many experimental results and comparisons. The entire process, from receiving the activated NADs to collecting and storing them after counting was executed successfully in a field based operation. Under normal conditions at LLNL, detectors are ready and available 24/7 to perform the necessary measurement of nuclear accident components. Likewise LLNL maintains processing laboratories that are separated from the areas where measurements occur, but contained within the same facility for easy movement from processing area to measurement area. In the event of a loss of LLNL permanent facilities, the Caliban and previous Silene exercises have demonstrated that LLNL can establish field operations that will very good nuclear accident dosimetry results. There are still several aspects of LLNL's nuclear accident dosimetry program that have not been tested or confirmed. For instance, LLNL's method for using of biological samples (blood and hair) has not been verified since the method was first developed in the 1980's. Because LLNL and the other DOE

    1990-10-01

    The Department of Energy`s Office of Civilian Radioactive Waste Management (OCRWM) Program is studying Yucca Mountain, Nevada as a suitable site for the first US high-level nuclear waste repository. Lawrence Livermore National Laboratory (LLNL) has the responsibility for designing and developing the waste package for the permanent storage of high-level nuclear waste. This report is a summary of the technical activities for the LLNL/YMP Nuclear Waste Disposal Container Fabrication and Closure Development Project. Candidate welding closure processes were identified in the Phase 1 report. This report discusses Phase 2. Phase 2 of this effort involved laboratory studies to determine the optimum fabrication and closure processes. Because of budget limitations, LLNL narrowed the materials for evaluation in Phase 2 from the original six to four: Alloy 825, CDA 715, CDA 102 (or CDA 122) and CDA 952. Phase 2 studies focused on evaluation of candidate material in conjunction with fabrication and closure processes.

    The mission of the Engineering Research, Development, and Technology Program at Lawrence Livermore National Laboratory (LLNL) is to develop the technical staff and the technology needed to support current and future LLNL programs. To accomplish this mission, the Engineering Research, Development, and Technology Program has two important goals: (1) to identify key technologies and (2) to conduct high-quality work to enhance our capabilities in these key technologies. To help focus our efforts, we identify technology thrust areas and select technical leaders for each area. The thrust areas are integrated engineering activities and, rather than being based on individual disciplines, they are staffed by personnel from Electronics Engineering, Mechanical Engineering, and other LLNL organizations, as appropriate. The thrust area leaders are expected to establish strong links to LLNL program leaders and to industry; to use outside and inside experts to review the quality and direction of the work; to use university contacts to supplement and complement their efforts; and to be certain that we are not duplicating the work of others. This annual report, organized by thrust area, describes activities conducted within the Program for the fiscal year 1992. Its intent is to provide timely summaries of objectives, theories, methods, and results. The nine thrust areas for this fiscal year are: Computational Electronics and Electromagnetics; Computational Mechanics; Diagnostics and Microelectronics; Emerging Technologies; Fabrication Technology; Materials Science and Engineering; Microwave and Pulsed Power; Nondestructive Evaluation; and Remote Sensing and Imaging, and Signal Engineering.

    2017-03-21

    Aboriginal and Torres Strait Islander Australians (hereafter respectfully Indigenous Australians) claim that they have been over-researched without corresponding research benefit. This claim raises two questions. The first, which has been covered to some extent in the literature, is about what type(s) of research are likely to achieve benefits for Indigenous people. The second is how researchers report the impact of their research for Indigenous people. This systematic review of Indigenous health reviews addresses the second enquiry. Fourteen electronic databases were systematically searched for Indigenous health reviews which met eligibility criteria. Two reviewers assessed their characteristics and methodological rigour using an a priori protocol. Three research hypotheses were stated and tested: (1) reviews address Indigenous health priority needs; (2) reviews adopt best practice guidelines on research conduct and reporting in respect to methodological transparency and rigour, as well as acceptability and appropriateness of research implementation to Indigenous people; and (3) reviews explicitly report the incremental impacts of the included studies and translation of research. We argue that if review authors explicitly address each of these three hypotheses, then the impact of research for Indigenous peoples' health would be explicated. Seventy-six reviews were included; comprising 55 journal articles and 21 Australian Government commissioned evidence review reports. While reviews are gaining prominence and recognition in Indigenous health research and increasing in number, breadth and complexity, there is little reporting of the impact of health research for Indigenous people. This finding raises questions about the relevance of these reviews for Indigenous people, their impact on policy and practice and how reviews have been commissioned, reported and evaluated. The findings of our study serve two main purposes. First, we have identified knowledge and

  13. National Uranium Resource Evaluation Program: the Hydrogeochemical Stream Sediment Reconnaissance Program at LLNL

    International Nuclear Information System (INIS)

    Higgins, G.H.

    1980-08-01

    From early 1975 to mid 1979, Lawrence Livermore National Laboratory (LLNL) participated in the Hydrogeochemical Stream Sediment Reconnaissance (HSSR), part of the National Uranium Resource Evaluation (NURE) program sponsored by the Department of Energy (DOE). The Laboratory was initially responsible for collecting, analyzing, and evaluating sediment and water samples from approximately 200,000 sites in seven western states. Eventually, however, the NURE program redefined its sampling priorities, objectives, schedules, and budgets, with the increasingly obvious result that LLNL objectives and methodologies were not compatible with those of the NURE program office, and the LLNL geochemical studies were not relevant to the program goal. The LLNL portion of the HSSR program was consequently terminated, and all work was suspended by June 1979. Of the 38,000 sites sampled, 30,000 were analyzed by instrumental neutron activation analyses (INAA), delayed neutron counting (DNC), optical emission spectroscopy (OES), and automated chloride-sulfate analyses (SC). Data from about 13,000 sites have been formally reported. From each site, analyses were published of about 30 of the 60 elements observed. Uranium mineralization has been identified at several places which were previously not recognized as potential uranium source areas, and a number of other geochemical anomalies were discovered

  14. LLNL Site plan for a MOX fuel lead assembly mission in support of surplus plutonium disposition

    Bronson, M.C.

    1997-10-01

    The principal facilities that LLNL would use to support a MOX Fuel Lead Assembly Mission are Building 332 and Building 334. Both of these buildings are within the security boundary known as the LLNL Superblock. Building 332 is the LLNL Plutonium Facility. As an operational plutonium facility, it has all the infrastructure and support services required for plutonium operations. The LLNL Plutonium Facility routinely handles kilogram quantities of plutonium and uranium. Currently, the building is limited to a plutonium inventory of 700 kilograms and a uranium inventory of 300 kilograms. Process rooms (excluding the vaults) are limited to an inventory of 20 kilograms per room. Ongoing operations include: receiving SSTS, material receipt, storage, metal machining and casting, welding, metal-to-oxide conversion, purification, molten salt operations, chlorination, oxide calcination, cold pressing and sintering, vitrification, encapsulation, chemical analysis, metallography and microprobe analysis, waste material processing, material accountability measurements, packaging, and material shipping. Building 334 is the Hardened Engineering Test Building. This building supports environmental and radiation measurements on encapsulated plutonium and uranium components.

    The principal facilities that LLNL would use to support a MOX Fuel Lead Assembly Mission are Building 332 and Building 334. Both of these buildings are within the security boundary known as the LLNL Superblock. Building 332 is the LLNL Plutonium Facility. As an operational plutonium facility, it has all the infrastructure and support services required for plutonium operations. The LLNL Plutonium Facility routinely handles kilogram quantities of plutonium and uranium. Currently, the building is limited to a plutonium inventory of 700 kilograms and a uranium inventory of 300 kilograms. Process rooms (excluding the vaults) are limited to an inventory of 20 kilograms per room. Ongoing operations include: receiving SSTS, material receipt, storage, metal machining and casting, welding, metal-to-oxide conversion, purification, molten salt operations, chlorination, oxide calcination, cold pressing and sintering, vitrification, encapsulation, chemical analysis, metallography and microprobe analysis, waste material processing, material accountability measurements, packaging, and material shipping.

    In the interest of promoting the international exchange of technical expertise, the US Department of Energy’s Office of Emergency Operations (NA-40) and the French Commissariat à l'Energie Atomique et aux énergies alternatives (CEA) requested that the National Atmospheric Release Advisory Center (NARAC) of Lawrence Livermore National Laboratory (LLNL) in Livermore, California host a joint table top exercise with experts in emergency management and atmospheric transport modeling. In this table top exercise, LLNL and CEA compared each other’s flow and dispersion models. The goal of the comparison is to facilitate the exchange of knowledge, capabilities, and practices, and to demonstrate the utility of modeling dispersal at different levels of computational fidelity. Two modeling approaches were examined, a regional scale modeling approach, appropriate for simple terrain and/or very large releases, and an urban scale modeling approach, appropriate for small releases in a city environment. This report is a summary of LLNL and CEA modeling efforts from this exercise. Two different types of LLNL and CEA models were employed in the analysis: urban-scale models (Aeolus CFD at LLNL/NARAC and Parallel- Micro-SWIFT-SPRAY, PMSS, at CEA) for analysis of a 5,000 Ci radiological release and Lagrangian Particle Dispersion Models (LODI at LLNL/NARAC and PSPRAY at CEA) for analysis of a much larger (500,000 Ci) regional radiological release. Two densely-populated urban locations were chosen: Chicago with its high-rise skyline and gridded street network and Paris with its more consistent, lower building height and complex unaligned street network. Each location was considered under early summer daytime and nighttime conditions. Different levels of fidelity were chosen for each scale: (1) lower fidelity mass-consistent diagnostic, intermediate fidelity Navier-Stokes RANS models, and higher fidelity Navier-Stokes LES for urban-scale analysis, and (2) lower-fidelity single

    2007-01-01

    The KINS already issued the safety review guidance for pressurized LWRs. But the safety review guidance for research and training reactors were not developed. So, the technical standard including safety review guidance for domestic research and training reactors has been applied mutates mutandis to those of nuclear power plants. It is often difficult for the staff to effectively perform the safety review of applications for the permit by the licensee, based on peculiar safety review guidance. The NRC and NSC provide the safety review guidance for test and research reactors and European countries refer to IAEA safety requirements and guides. The safety review guide (SRG) of research and training reactors was developed considering descriptions of the NUREG- 1537 Part 2, previous experiences of safety review and domestic regulations for related facilities. This study provided the safety review guidance for research and training reactors and surveyed the difference of major acceptance criteria or characteristics between the SRG of pressurized light water reactor and research and training reactors

  9. Attachment theory: A review of research

    2005-01-01

    Full Text Available Research of attachment is numerous and versatile. They differ according to problems addressed, methodology applied (longitudinal studies, studies with horizontal designs, different instruments used, different methods of data analysis, and characteristics of samples involved (concerning age socio/economic status, family ecology. The research is commonly relied on the core assumptions of the theory itself, and the shared characteristic is orientation to explore complex phenomena of human experience and functioning. From the vast variety of research only those who most directly test the basic assumptions of the attachment theory are focused and addressed in the paper: representation of patterns of attachment in the childhood and adulthood, stability and change of attachment security from infancy to early adulthood, transgenerational transmission of attachment characteristics, the place and the role of attachment behavioral system in the personality development. The aim of the paper is to highlight the basic research and theory issues and directions, and illustrate them with concrete research date.

  11. Getting the justification for research ethics review right.

    Science.gov (United States)

    Dunn, Michael

    2013-08-01

    Dyck and Allen claim that the current model for mandatory ethical review of research involving human participants is unethical once the harms that accrue from the review process are identified. However, the assumptions upon which the authors assert that this model of research ethics governance is justified are false. In this commentary, I aim to correct these assumptions, and provide the right justificatory account of the requirement for research ethics review. This account clarifies why the subsequent arguments that Dyck and Allen make in the paper lack force, and why the 'governance problem' in research ethics that they allude to ought to be explained differently.

  12. Review of existing issues, ethics and practices in general medical research and in radiation protection research

    International Nuclear Information System (INIS)

    Schreiner-Karoussou, A.

    2008-01-01

    A literature review was carried out in relation to general medical research and radiation protection research. A large number of documents were found concerning the subject of ethics in general medical research. For radiation protection research, the number of documents and the information available is very limited. A review of practices in 13 European countries concerning general medical research and radiation protection research was carried out by sending a questionnaire to each country. It was found that all countries reviewed were well regulated for general medical research. For research that involves ionising radiation, the UK and Ireland are by far the most regulated countries. For other countries, there does not seem to be much information available. From the literature review and the review of practices, a number of existing ethical issues were identified and exposed, and a number of conclusions were drawn. (authors)

    Energy Technology Data Exchange (ETDEWEB)

    Spada, M.L.; Forman, J.I.; SLovin, K.A.

    1995-12-31

    One year after a Marketing reorganization in an electric utility preparing for competition and better meeting customer needs, the newly established research team lives to tell about it. The new research function was formulated as a result of a corporate reorganization designed to better position the Company to meet the challenges occurring in today`s electric utility industry. Many senior level managers from different parts of the Company participated in this reengineering process. Their perspectives included customer services, marketing, energy services, engineering, rates and corporate communications. One of their major recommendations was to form a centralized or coordinated research function for the Company. They saw that the future of successful utility marketing and business planning would depend heavily on the success of a research and analysis function. Other major recommendations included the formulation of additional groups: market planning, product R & D, pricing, evaluation and marketing information systems. Once the senior team recommended general functions and responsibilities of each of the suggested groups mentioned above, the Company assembled one junior level team to study each group in more detail. The junior team assigned to the research function spent several months canvassing and investigating what research and data were currently available internally, who performs it and how it is used. The junior team reported not only on what is, but also on what a research function should be in the evolving electric utility industry and what steps can be taken to move towards those goals. The junior team concluded that there was a wealth of information available and much research activity taking place internally.

    2009-12-09

    Gas hydrates sediments have the potential of providing a huge amount of natural gas for human use. Hydrate sediments have been found in many different regions where the required temperature and pressure conditions have been satisfied. Resource exploitation is related to the safe dissociation of the gas hydrate sediments. Basic depressurization techniques and thermal stimulation processes have been tried in pilot efforts to exploit the resource. There is a growing interest in gas hydrates all over the world due to the inevitable decline of oil and gas reserves. Many different countries are interested in this valuable resource. Unsurprisingly, developed countries with limited energy resources have taken the lead in worldwide gas hydrates research and exploration. The goal of this research project is to collect information in order to record and evaluate the relative strengths and goals of the different gas hydrates programs throughout the world. A thorough literature search about gas hydrates research activities has been conducted. The main participants in the research effort have been identified and summaries of their past and present activities reported. An evaluation section discussing present and future research activities has also been included.

  19. Historical review of radiation research in Japan

    International Nuclear Information System (INIS)

    Yamasaki, F.

    1979-01-01

    The outline of the history of radiation research in Japan is written in connection with the names of researchers. Yoshio Nishina was a pioneer, who derived the Klein-Nishina formula for the scattering of hard X-ray by free electrons. In 1935, the first nuclear experiment laboratory was constructed in the Institute of Physical and Chemical Research. Two cyclotrons, 26 in and 60 in pole face diameter, and a high voltage Cockcroft-Walton type ion accelerator were installed. Irradiation of insects and plants with fast neutrons was attempted to examine the biological effect. In August, 1945, atomic bombs exploded in Hiroshima and Nagasaki. In 1950, radioisotopes were available. In early March, 1954, Bikini accident occurred. One fishing vessel was contaminated by radioactive fallout, and to investigate the effect of radioactivity, a committee consisted of investigators of physics, chemistry, medicine, biology, fisheries and geophysics was organized. The Japan Atomic Energy Research Institute was established in June, 1956. Several institutions for the peaceful use of atomic energy were established. The hybrid spark chamber to image the distribution of β-emitting isotopes on a plane surface was constructed in Nagoya University. As for the national project on food irradiation, one laboratory has played the role in irradiation techniques. Researches on radiation chemistry in universities, governmental and commercial organizations have been progressing steadily, and the machines for nanosecond to picosecond pulse radiolysis are working.

    2012-01-01

    Internet addiction (IA) is a mental illness emerged in recent years with increasing use of computer and internet. The serious consequences such as mental and physical illness and social function impairment caused by IA have attracted extensive attention of the whole society. IA affects human beings at a high prevalence all over the world which has highlighted the importance of prevention and treatment of IA. Although there is still debate about definition of IA, increasing evidences including the result from genetic research,neurobiology study and clinical manifestation show that IA may share the same mechanisms with substance addiction, and be probably classified as behavioral addiction which is represented by pathological gambling. However, since the study on IA is yet on the initial stage and neuro biological research on IA is still limited, more reliable investigations especially neuro biological research remains uppermost in this area.

  9. Theoretical proposals in bullying research: a review

    Directory of Open Access Journals (Sweden)

    Silvia Postigo

    2013-05-01

    Full Text Available Four decades of research into peer bullying have produced an extensive body of knowledge. This work attempts to provide an integrative theoretical framework, which includes the specific theories and observations. The main aim is to organize the available knowledge in order to guide the development of effective interventions. To that end, several psychological theories are described that have been used and/or adapted with the aim of understanding peer bullying. All of them, at different ecological levels and different stages of the process, may describe it in terms of the relational dynamics of power. It is concluded that research needs to take this integrative framework into account, that is to say to consider multi-causal and holistic approaches to bullying. For the intervention, regardless of the format or the target population, the empowerment of the individuals, and the social awareness of the use and abuse of personal power are suggested.

  10. The systematic review as a research process in music therapy.

    Science.gov (United States)

    Hanson-Abromeit, Deanna; Sena Moore, Kimberly

    2014-01-01

    Music therapists are challenged to present evidence on the efficacy of music therapy treatment and incorporate the best available research evidence to make informed healthcare and treatment decisions. Higher standards of evidence can come from a variety of sources including systematic reviews. To define and describe a range of research review methods using examples from music therapy and related literature, with emphasis on the systematic review. In addition, the authors provide a detailed overview of methodological processes for conducting and reporting systematic reviews in music therapy. The systematic review process is described in five steps. Step 1 identifies the research plan and operationalized research question(s). Step 2 illustrates the identification and organization of the existing literature related to the question(s). Step 3 details coding of data extracted from the literature. Step 4 explains the synthesis of coded findings and analysis to answer the research question(s). Step 5 describes the strength of evidence evaluation and results presentation for practice recommendations. Music therapists are encouraged to develop and conduct systematic reviews. This methodology contributes to review outcome credibility and can determine how information is interpreted and used by clinicians, clients or patients, and policy makers. A systematic review is a methodologically rigorous research method used to organize and evaluate extant literature related to a clinical problem. Systematic reviews can assist music therapists in managing the ever-increasing literature, making well-informed evidence based practice and research decisions, and translating existing music-based and nonmusic based literature to clinical practice and research development. © the American Music Therapy Association 2014.

    Lee, S.

    1982-01-01

    The energy trends of Malaysia projected for the next few decades are briefly discussed as a background to the rationale for Malaysian research into new forms of energy including plasma fusion. The planning of this research started nearly two decades ago. Today research facilities at PLUM centre on two capacitor banks, one rated at 40 kV, 48 kJ, 2 MA short circuit current and the other at 60 kV, 40 kJ, 2 MA. Other equipment includes several smaller capacitor banks, vacuum systems, oscilloscopes, diagnostic systems, a screened room, a transient digitizer, an Imacon camera and a 100 MW pulsed ruby laser for discharge initiation and diagnostics. The research devices include two plasma focus machines, one vacuum fusion spark, a shock tube and minor experiments like the glow discharge. The main focus facility, the UMDPF1, was designed and built entirely by indigenous effort, using 40 kV capacitors donated by Britain under the Colombo Plan. Difficulties were encountered especially in the need to adapt what is locally available or readily importable to all phases of the design, construction, testing and measurement. Nevertheless, the focus group has achieved the following results: measurement, in 1973, of neutrons produced in the deuterium focus; current, voltage, magnetic field and pressure measurements to interpret plasma dynamics and focus mechanism and to compare with computer simulation of plasma trajectory and configuration; soft X-ray measurements to determine electron temperature; study of the effect on the focus of rotation and multiple ionization up to Argon XVIII; and optimization of focus performance as judged from neutron yield. In 1977 PLUM acquired the Juelich DPF1 which was reassembled as a fast focus, the UMDPF2. This device has been converted to operate as a vacuum spark with the aim of demonstrating the spark as a neutron source when using a deuterided anode. We have measured temperatures of 8 keV in the dense plasma spots. Plasma research work here has

  18. Research review: Indoor air quality control techniques

    International Nuclear Information System (INIS)

    Fisk, W.J.

    1986-10-01

    Techniques for controlling the concentration of radon, formaldehyde, and combustion products in the indoor air are reviewed. The most effective techniques, which are generally based on limiting or reducing indoor pollutant source strengths, can decrease indoor pollutant concentrations by a factor of 3 to 10. Unless the initial ventilation rate is unusually low, it is difficult to reduce indoor pollutant concentrations more than approximately 50% by increasing the ventilation rate of an entire building. However, the efficiency of indoor pollutant control by ventilation can be enhanced through the use of local exhaust ventilation near concentrated sources of pollutants, by minimizing short circuiting of air from supply to exhaust when pollutant sources are dispersed and, in some situations, by promoting a displacement flow of air and pollutants toward the exhaust. Active air cleaning is also examined briefly. Filtration and electrostatic air cleaning for removal of particles from the indoor air are the most practical and effective currently available techniques of air cleaning. 49 refs., 7 figs

    2018-03-01

    Full Text Available Political, religious, sports and business leaders across the world have been under scrutiny regarding allegedly unethical behaviors. The current study analyzes the use of responsible leadership in management research. Using a sample of 64 articles published in SSCI-indexed journals over 10 years (2006-2016, we carried out a bibliometric analysis to understand the intellectual structure of the responsible leadership literature. The results of authorship, citation and co-citation, and factor analyses reveal the most prolific authors and the most notable journals writing and publishing on responsible leadership. The most cited works are theoretical, using Western frameworks and cultures, and focus on the concept of responsible leadership; only a few empirical/case study articles appear. Also, the most prevalent links are between theoretical works and highlight the conceptualization, understanding, and roles and parameters of responsible leaders. Six distinct factors emerge, denoting the groups of studies devoted to the evolution of leadership, transformational leadership, stakeholder theory and leadership, conceptualization and understanding of the topic, and roles of responsible leaders. These various research topics show the central tenets of responsible leadership, as well as the existing gaps in the existent literature.

  4. A short review of memory research

    Directory of Open Access Journals (Sweden)

    Igor Areh

    2004-09-01

    Full Text Available Scientific research on memory began at the end of 19th century with studies of semantic and/or long term memory. In most cases memory was interpreted as a storehouse for various data and the quality of the storehouse was usually defined by a quantity of recalled data. The research work was concentrated on specificity of the connection between memory and learning. At that time few authors developed theories which were rare, uncommon and before their time (e.g.: Bartlett, Ribot, Freud. Even after 20th century, when behavioural stimulus-response approach began to dominate, the measure of memory quality was still the quantity of memory recall. In the 1960th the rise of cognitive psychology began, the computer metaphor was born and finally the behavioural comprehension of cognitive system was surpassed. Cognitive system was understood as a computer-like interface between an organism and environment. In recent years the computer metaphor is no longer dominant. New and efficient concepts are moving forward. Quantity of data recall, as the measure of memory quality, is not so important any more – attention is focused on accuracy of memory recall.

  9. Dissemination bias in systematic reviews of animal research: a systematic review.

    Directory of Open Access Journals (Sweden)

    Katharina F Mueller

    Full Text Available Systematic reviews of preclinical studies, in vivo animal experiments in particular, can influence clinical research and thus even clinical care. Dissemination bias, selective dissemination of positive or significant results, is one of the major threats to validity in systematic reviews also in the realm of animal studies. We conducted a systematic review to determine the number of published systematic reviews of animal studies until present, to investigate their methodological features especially with respect to assessment of dissemination bias, and to investigate the citation of preclinical systematic reviews on clinical research.Eligible studies for this systematic review constitute systematic reviews that summarize in vivo animal experiments whose results could be interpreted as applicable to clinical care. We systematically searched Ovid Medline, Embase, ToxNet, and ScienceDirect from 1st January 2009 to 9th January 2013 for eligible systematic reviews without language restrictions. Furthermore we included articles from two previous systematic reviews by Peters et al. and Korevaar et al.The literature search and screening process resulted in 512 included full text articles. We found an increasing number of published preclinical systematic reviews over time. The methodological quality of preclinical systematic reviews was low. The majority of preclinical systematic reviews did not assess methodological quality of the included studies (71%, nor did they assess heterogeneity (81% or dissemination bias (87%. Statistics quantifying the importance of clinical research citing systematic reviews of animal studies showed that clinical studies referred to the preclinical research mainly to justify their study or a future study (76%.Preclinical systematic reviews may have an influence on clinical research but their methodological quality frequently remains low. Therefore, systematic reviews of animal research should be critically appraised before

  10. DOE/LLNL verification symposium on technologies for monitoring nuclear tests related to weapons proliferation

    Nakanishi, K.K.

    1993-01-01

    The rapidly changing world situation has raised concerns regarding the proliferation of nuclear weapons and the ability to monitor a possible clandestine nuclear testing program. To address these issues, Lawrence Livermore National Laboratory's (LLNL) Treaty Verification Program sponsored a symposium funded by the US Department of Energy's (DOE) Office of Arms Control, Division of Systems and Technology. The DOE/LLNL Symposium on Technologies for Monitoring Nuclear Tests Related to Weapons Proliferation was held at the DOE's Nevada Operations Office in Las Vegas, May 6--7,1992. This volume is a collection of several papers presented at the symposium. Several experts in monitoring technology presented invited talks assessing the status of monitoring technology with emphasis on the deficient areas requiring more attention in the future. In addition, several speakers discussed proliferation monitoring technologies being developed by the DOE's weapons laboratories

  11. Human rights, politics, and reviews of research ethics.

    Science.gov (United States)

    Beyrer, Chris; Kass, Nancy E

    2002-07-20

    Although the human rights movement and the sphere of research ethics have overlapping principles and goals, there has been little attempt to incorporate external political and human rights contexts into research ethics codes or ethics reviews. Every element of a research ethics review--the balance of risks and benefits, the assurance of rights for individual participants, and the fair selection of research populations--can be affected by the political and human rights background in which a study is done. Research that at first seems to be low in risk may become high in risk if implemented in a country where the government might breach the confidentiality of study results or where results might be used to deport a refugee group. Researchers should determine whether research could or should be done by consulting human rights organisations and, when possible, a trusted colleague, to learn the background political context and human rights conditions of the settings in which they propose to do research.

  12. Mapping the organizational culture research in nursing: a literature review.

    Science.gov (United States)

    Scott-Findlay, Shannon; Estabrooks, Carole A

    2006-12-01

    This paper reports a critical review of nursing organizational culture research studies with the objectives of: (1) reviewing theoretical and methodological characteristics of the studies and (2) drawing inferences specific to the state of knowledge in this field. Organizational culture is regarded as significant in influencing research use in clinical practice yet it is not understood how culture shapes practitioners' behaviours. Only one review of this empirical literature in nursing has been completed. Using selected computerized databases, published nursing research studies in English that examine organizational culture were accessed. Organizational culture studies were categorized using Hatch's three perspectives on organizational culture: (1) modern, (2) symbolic-interpretive and (3) postmodern. The review was conducted in 2005. Twenty-nine studies were in the final data set. Results pointed to variations in cultural definitions and incorporation of organizational sciences theory. In classifying the studies, modern perspectives dominated (n = 22), symbolic-interpretive approaches were an emerging group (n = 6) and one study was unclassifiable. Our results expand current cultural instrument reviews by pinpointing tools that have been previously overlooked and by identifying ongoing theoretical and methodological challenges for researchers. An exclusive reliance on modernistic approaches in organizational culture research cannot yield a complete understanding of the phenomenon. Rather, the field could benefit from a variety of cultural approaches. In a similar vein, researchers need to be mindful of the terminology and the unit of analysis they use in their research, as these are the two largest research challenges.

  1. Performance of HEPA filters at LLNL following the 1980 and 1989 earthquakes

    International Nuclear Information System (INIS)

    Bergman, W.; Elliott, J.; Wilson, K.

    1995-01-01

    The Lawrence Livermore National Laboratory has experienced two significant earthquakes for which data is available to assess the ability of HEPA filters to withstand seismic conditions. A 5.9 magnitude earthquake with an epicenter 10 miles from LLNL struck on January 24, l980. Estimates of the peak ground accelerations ranged from 0.2 to 0.3 g. A 7.0 magnitude earthquake with an epicenter about 50 miles from LLNL struck on October 17, 1989. Measurements of the ground accelerations at LLNL averaged 0.1 g. The results from the in-place filter tests obtained after each of the earthquakes were compiled and studied to determine if the earthquakes had caused filter leakage. Our study showed that only the 1980 earthquake resulted in a small increase in the number of HEPA filters developing leaks. In the 12 months following the 1980 and 1989 earthquakes, the in-place filter tests showed 8.0% and 4.1% of all filters respectively developed leaks. The average percentage of filters developing leaks from 1980 to 1993 was 3.3%+/-1.7%. The increase in the filter leaks is significant for the 1980 earthquake, but not for the 1989 earthquake. No contamination was detected following the earthquakes that would suggest transient releases from the filtration system

    2018-02-01

    Full Text Available The industrialization of new energy vehicles is an important way to promote the sustainable development of automobile industry, and it is also the key measure to solve the problems of energy and environment. As an important type of new energy vehicles, electric vehicles will play an important role in the future competition in the automotive industry, especially in the field of electric vehicle driven by wheel. With the advantages of compact structure, high power density, low working noise and good heat dissipation performance, the AFPM motor has gradually become the preferred object of the hub driving device. Based on the statement of the technical development and research status about AFPM motor, this paper mainly analyzes the engineering application and technical problems of AFPM motor in hub drive, especially the matching of AFPM motor with other systems and the problem of heat dissipation at high load conditions, and looks forward to the key role in the future development of the automotive industry. This paper will play a certain reference and guiding role in the application of AFPM motor in the field of new energy vehicles.

  6. A Methodological Review of Meditation Research

    Science.gov (United States)

    Thomas, John W.; Cohen, Marc

    2014-01-01

    Despite over 50 years of research into the states of consciousness induced by various meditation practices, no clear neurophysiological signatures of these states have been found. Much of this failure can be attributed to the narrow range of variables examined in most meditation studies, with the focus being restricted to a search for correlations between neurophysiological measures and particular practices, without documenting the content and context of these practices. We contend that more meaningful results can be obtained by expanding the methodological paradigm to include multiple domains including: the cultural setting (“the place”), the life situation of the meditator (“the person”), details of the particular meditation practice (‘the practice’), and the state of consciousness of the meditator (“the phenomenology”). Inclusion of variables from all these domains will improve the ability to predict the psychophysiological variables (“the psychophysiology”) associated with specific meditation states and thus explore the mysteries of human consciousness.

    2016 was a year of strategy, analysis and moving forward. We launched January with a strategic planning process. Building on the Lab’s Strategic Plan and Purpose Statement, we created a process that reached out to Lab leadership, scientists & engineers, and Research Library (RL) staff. An external consultant was engaged to help drive the process and to lead a fullday staff retreat. A survey was created and administered to staff, seeking feedback on priorities and direction. A parallel survey was created for stakeholders. Stakeholder questions began with the macro – from the external climate to Lab and division priorities – to the micro concerning priorities and directions for the RL. Stakeholders were personally interviewed by teams of two that included an interviewer and a scribe. These thirty-plus interviews were collated into a spreadsheet. A sociologist provided semantic analysis for the feedback, creating an impact document of the interviews. The full day retreat provided an opportunity for staff to build on their feedback as well as stakeholder feedback. A great deal of brainstorming led to categorized priorities and scenarios. The RL Compass Team, encompassing library leadership, moved the next stage of the process forward by taking retreat feedback and creating a first draft of a plan. Two more rounds of feedback with smaller staff groups as well as the Library Advisory Board led to the final plan. The core plan is included in this report.

    2001-01-01

    The purpose of this research was to support the optics finishing development work for the NIF, the National Ignition Facility. One of the major expenses for the construction of NIF is the cost of finishing of the large aperture optics. One way to significantly reduce the cost of the project is to develop processes to reduce the amount of time necessary to polish the more than 3,000 amplifier slabs. These slabs are rectangular with an aspect ratio of more than twenty to one and are made of a very temperature sensitive glass, Nd doped phosphate laser glass. As a result of this effort, we could potentially reduce the time necessary to polish each surface of an amplifier from 20-30 hours of run time to under an hour to achieve the same removal and still maintain a flatness of between one to three waves concave figure. We also feel confident that we can polish rectangular thermally sensitive glass flat by use of temperature control of the polishing platen, pad curvature, slurry concentration with temperature control, pad rotation, and pressure; although further, larger scale experiments are necessary to gain sufficient confidence that such a procedure could be successfully fielded

  11. Review of arctic Norwegian bioremediation research

    Traditional oil spill onshore clean up in arctic and sub-arctic parts of Norway involves methods that are both time-consuming, and labor intensive. The applicability of the methods depends both on the environmental constraints of the area, and the availability of man-power. If oil exploration is successful this will mean that the exploitation of oil moves north into the arctic regions of Norway. This area is remote, both in terms of accessability and lack of inhabitants. The threat to natural resources that always accompanies oil activities, will move into areas that are considered vulnerable, and which are also highly valued in terms of natural resources. Contingency measures must be adapted both to be feasible and to meet the framework in which they must operate. This situation has increased the focus on alternative methods for oil spill clean-ups, especially on shorelines. SINTEF (The Foundation for Scientific and Industrial Research at the Norwegian Institute of Technology) Applied Chemistry has evaluated the application of fertilizers as a practical measure in oil spill treatment for years. Several fertilizers have been assessed, in different environments. The effect of these products is difficult to establish categorically since their efficiency seems to be greatly dependent on the environment in which the test is conducted, as well as the design of the test. The aim of this paper is to summarize and evaluate a series of tests conducted with INIPOL EAP22, an oil soluble fertilizer developed by Elf Aquitaine, and water soluble fertilizers. The paper will emphasize treatment failure and success, and point out some necessary prerequisites that must be met for fertilizers to work. 14 refs., 3 figs

    2006-09-01

    ETHICAL DECISION-MAKING ABOUT TRAUMA-RELATED STUDIES requires a flexible approach that counters assumptions and biases about victims, assures a favorable ethical cost-benefit ratio, and promotes advancement of knowledge that can benefit survivors of traumatic stress. This paper reviews several ethical issues in the field of traumatic stress: benefit and risks in trauma-related research, whether trauma-related research poses unique risks and if so what those might be, informed consent and mandatory reporting, and supervision of trauma-related research. For each topic, we review potential ethical issues, summarize the research conducted thus far to inform ethical practice, and recommend future practice, research questions and policies to advance the field so that research on trauma can continue to be a win-win situation for all stakeholders in the research enterprise.

    2015-09-01

    The recent interest in systematic review methods in bioethics has highlighted the need for greater transparency in all literature review processes undertaken in bioethics projects. In this article, I articulate features of a good bioethics literature review that does not aim to be systematic, but rather to capture and analyse the key ideas relevant to a research question. I call this a critical interpretive literature review. I begin by sketching and comparing three different types of literature review conducted in bioethics scholarship. Then, drawing on Dixon-Wood's concept of critical interpretive synthesis, I put forward six features of a good critical interpretive literature review in bioethics: answering a research question, capturing the key ideas relevant to the research question, analysing the literature as a whole, generating theory, not excluding papers based on rigid quality assessment criteria, and reporting the search strategy. © 2015 John Wiley & Sons Ltd.

    1999-01-01

    An NEA study on safety research needs of Russian-designed reactors, carried out in 1996, strongly recommended that a strategic plan for safety research be developed with respect to Russian nuclear power plants. Such a plan was developed at the Russian International Nuclear Safety Centre (RINSC) of the Russian Ministry of Atomic Energy (Minatom). The Strategic Plan is designed to address high-priority safety-research needs, through a combination of domestic research, the application of appropriate foreign knowledge, and collaboration. It represents major progress toward developing a comprehensive and coherent safety-research programme for Russian nuclear power plants (NPPs). The NEA undertook its review of the Strategic Plan with the objective of providing independent verification on the scope, priority, and content of the research described in the Plan based upon the experience of the international group of experts. The principal conclusions of the review and the general comments of the NEA group are presented. (K.A.)

    To review the current state of science using big data to advance Alzheimer's disease (AD) research and practice. In particular, we analyzed the types of research foci addressed, corresponding methods employed and study findings reported using big data in AD. Systematic review was conducted for articles published in PubMed from January 1, 2010 through December 31, 2015. Keywords with AD and big data analytics were used for literature retrieval. Articles were reviewed and included if they met the eligibility criteria. Thirty-eight articles were included in this review. They can be categorized into seven research foci: diagnosing AD or mild cognitive impairment (MCI) (n=10), predicting MCI to AD conversion (n=13), stratifying risks for AD (n=5), mining the literature for knowledge discovery (n=4), predicting AD progression (n=2), describing clinical care for persons with AD (n=3), and understanding the relationship between cognition and AD (n=3). The most commonly used datasets are AD Neuroimaging Initiative (ADNI) (n=16), electronic health records (EHR) (n=11), MEDLINE (n=3), and other research datasets (n=8). Logistic regression (n=9) and support vector machine (n=8) are the most used methods for data analysis. Big data are increasingly used to address AD-related research questions. While existing research datasets are frequently used, other datasets such as EHR data provide a unique, yet under-utilized opportunity for advancing AD research. Copyright © 2017 Elsevier B.V.

    Increasing demand for qualitative research within global health has emerged alongside increasing demand for demonstration of quality of research, in line with the evidence-based model of medicine. In quantitative health sciences research, in particular clinical trials, there exist clear and widely-recognised guidelines for conducting quality assurance of research. However, no comparable guidelines exist for qualitative research and although there are long-standing debates on what constitutes 'quality' in qualitative research, the concept of 'quality assurance' has not been explored widely. In acknowledgement of this gap, we sought to review discourses around quality assurance of qualitative research, as a first step towards developing guidance. A range of databases, journals and grey literature sources were searched, and papers were included if they explicitly addressed quality assurance within a qualitative paradigm. A meta-narrative approach was used to review and synthesise the literature. Among the 37 papers included in the review, two dominant narratives were interpreted from the literature, reflecting contrasting approaches to quality assurance. The first focuses on demonstrating quality within research outputs; the second focuses on principles for quality practice throughout the research process. The second narrative appears to offer an approach to quality assurance that befits the values of qualitative research, emphasising the need to consider quality throughout the research process. The paper identifies the strengths of the approaches represented in each narrative and recommend these are brought together in the development of a flexible framework to help qualitative researchers to define, apply and demonstrate principles of quality in their research. © 2011 Reynolds et al; licensee BioMed Central Ltd.

  19. Research ethics and Institutional Review Boards. The influence of moral constraints on emotion research.

    Science.gov (United States)

    Sontag, Michael

    2012-01-01

    Researchers in the twenty-first century face a set of challenges unknown to researchers a half century ago--the need to justify the moral acceptability of their research methods through formal review processes. However, the role that moral constraints play in the development and demise of scientific theories has largely gone unappreciated. The rise of Institutional Review Boards (IRB) in the 1960s compounded the impact of moral constraints on scientific research and on the theories that develop out of such highly monitored research. To demonstrate the effects of moral constraints on scientific theory and research, this paper offers a history and analysis of the interaction between evolving moral standards and twentieth century emotion theory. Recommendations regarding IRB reform are also reviewed. The paper concludes by arguing that, while appropriate IRB reform is important, it cannot eliminate the need for careful reflection on the broader forces that shape scientific practice and understanding.

    1995-01-01

    Australian research reactor review commenced in September 1992, the Review had the following Terms of Reference: Whether, on review of the benefits and costs for scientific, commercial, industrial and national interest reasons, Australia has a need for a new reactor; a review of the present reactor, HIFAR, to include: an assessment of national and commercial benefits and costs of operations, its likely remaining useful life and its eventual closure and decommissioning; if Australia has a need for a new nuclear research reactor, the Review will consider: possible locations for a new reactor, its environmental impact at alternative locations, recommend a preferred location, and evaluate matters associated with regulation of the facility and organisational arrangements for reactor-based research. From the Review findings the following recommendations were stated: keep HIFAR going; commission a PRA to ascertain HIFAR's remaining life and refurbishment possibilities; identify and establish a HLW repository; accept that neither HIFAR nor a new reactor can be completely commercial; any decision on a new neutron source must rest primarily on benefits to science and Australia's national interest; make a decision on a new neutron source in about five years' time (1998). Design Proposals for a New Reactor are specified

    The field of retail food environments research is relatively new in Canada. The objective of this scoping review is to provide an overview of retail food environments research conducted before July 2015 in Canada. Specifically, this review describes research foci and key findings, identifies knowledge gaps and suggests future directions for research. A search of published literature concerning Canadian investigations of retail food environment settings (food stores, restaurants) was conducted in July 2015 using PubMed, Web of Science, Scopus, PsychInfo and ERIC. Studies published in English that reported qualitative or quantitative data on any aspect of the retail food environment were included, as were conceptual papers and commentaries. Eighty-eight studies were included in this review and suggest that the field of retail food environments research is rapidly expanding in Canada. While only 1 paper was published before 2005, 66 papers were published between 2010 and 2015. Canadian food environments research typically assessed either the socio-economic patterning of food environments (n = 28) or associations between retail food environments and diet, anthropometric or health outcomes (n = 33). Other papers profiled methodological research, qualitative studies, intervention research and critical commentaries (n = 27). Key gaps in the current literature include measurement inconsistency among studies and a lack of longitudinal and intervention studies. Retail food environments are a growing topic of research, policy and program development in Canada. Consistent methods (where appropriate), longitudinal and intervention research, and close partnerships between researchers and key stakeholders would greatly advance the field of retail food environments research in Canada.

    Research evidence is required to guide optimal allied health practice and inform policymakers in primary health care. Factors that influence a positive research culture are not fully understood, and nor is the impact of a positive research culture on allied health professionals. The aim of this systematic review was to identify factors that affect allied health research culture and capacity. An extensive search of 11 databases was conducted in June 2015. Studies were included if they were published in English, had full-text availability and reported research findings relating to allied health professions. Study quality was evaluated using the McMaster Critical Review Forms. Fifteen studies were eligible for inclusion. A meta-analysis was not performed because of heterogeneity between studies. Allied health professionals perceive that their individual research skills are lower in comparison to their teams and organisation. Motivators for conducting research for allied health professionals include developing skills, increasing job satisfaction and career advancement. Barriers include a lack of time, limited research skills and other work roles taking priority. Multilayered strategies, such as collaborations with external partners and developing research leadership positions, aimed at addressing barriers and enablers, are important to enhance allied health research culture and capacity.

    Full Text Available The purpose of this paper is to review the academic literature available in the field of Entrepreneurial Intention (EI, and conduct a content analysis of the same for the purpose of classification and provide a comprehensive bibliography. Emerald full text, online database was searched to review the available literature on EI. The search resulted in only 118 publications where EI was mentioned as the primary research topic. The sample was further refined to only include papers with empirical research in qualitative and quantitative realms. The resultant of the refined sample was 69 research publications, which were classified in to mutually exclusive categories. The content analysis led to classification of literature on the basis of six categories viz. Publication Year, Journal, Research Area, Research Type, Base Theory and Population. The study identifies the history of research on EI and hints towards future research prospects in research in terms of industry, area of study, methodology, type of study, etc. The paper provides a list of field projects accompanied by a comprehensive bibliography that will be useful to both academicians and practitioners for studying existing research as well as for contemplating future research. This may be considered as the basic compilation and classification of available literature in the field of EI.

    Trafficking in persons (TIP) is a human rights violation with serious public health consequences. Unfortunately, assessing TIP and its health sequelae rigorously and reliably is challenging due to TIP's clandestine nature, variation in definitions of TIP, and the need to use research methods that ensure studies are ethical and feasible. To help guide practice, policy, and research to assess TIP and health, we undertook a systematic literature review of 70 peer-reviewed, published articles to (a) identify TIP and health research methods being used, (b) determine what we can learn about TIP and health from these varied methodologies, and (c) determine the gaps that exist in health-focused TIP research. Results revealed that there are various quantitative and qualitative data collection and analysis methods being used to investigate TIP and health. Furthermore, findings show that the limitations of current methodologies affect what is known about TIP and health. In particular, varying definitions, participant recruitment strategies, ethical standards, and outcome measures all affect what is known about TIP and health. Moreover, findings demonstrate an urgent need for representative and nonpurposive recruitment strategies in future investigations of TIP and health as well as research on risk and protective factors related to TIP and health, intervention effectiveness, long-term health outcomes, and research on trafficked people beyond women trafficked for sex. We offer recommendations for research, policy, and practice based on review results.

    2009-01-01

    As one of the major factors affecting second language learners' success to their acquisition achievement, motivation has been examined in a wide variety of research papers. It is thus instructive to conduct a critical review of both theoretical and empirical developments in SLA research from over the last few decades. This approach will provide a broad, and integrated perspective onto the current understanding of the complex topic of motivation. Such an undertaking is valuable for teachers, and researchers alike, in developing useful teaching methods, and finding future avenues of SLA motivation research respectively.The following paper provides an overview of recent theoretical and empirical findings, examines some of the problems and contradictions found/11 current SLA research, and gives an initial departure point for future directions of research in the area of motivation. The paper concludes with a discussion of some of the implications for teachers, and possible classroom strategies that axe drawn from the current body of motivation research.

  8. Researcher perspectives on publication and peer review of data.

    Directory of Open Access Journals (Sweden)

    John Ernest Kratz

    Full Text Available Data "publication" seeks to appropriate the prestige of authorship in the peer-reviewed literature to reward researchers who create useful and well-documented datasets. The scholarly communication community has embraced data publication as an incentive to document and share data. But, numerous new and ongoing experiments in implementation have not yet resolved what a data publication should be, when data should be peer-reviewed, or how data peer review should work. While researchers have been surveyed extensively regarding data management and sharing, their perceptions and expectations of data publication are largely unknown. To bring this important yet neglected perspective into the conversation, we surveyed ∼ 250 researchers across the sciences and social sciences- asking what expectations"data publication" raises and what features would be useful to evaluate the trustworthiness, evaluate the impact, and enhance the prestige of a data publication. We found that researcher expectations of data publication center on availability, generally through an open database or repository. Few respondents expected published data to be peer-reviewed, but peer-reviewed data enjoyed much greater trust and prestige. The importance of adequate metadata was acknowledged, in that almost all respondents expected data peer review to include evaluation of the data's documentation. Formal citation in the reference list was affirmed by most respondents as the proper way to credit dataset creators. Citation count was viewed as the most useful measure of impact, but download count was seen as nearly as valuable. These results offer practical guidance for data publishers seeking to meet researcher expectations and enhance the value of published data.

  13. Status of the SLAC/LBL/LLNL B-Factory and the BaBar detector

    International Nuclear Information System (INIS)

    Oddone, P.

    1994-08-01

    The primary motivation of the Asymmetric B-Factory is the study of CP violation. The decay of B mesons and, in particular, the decay of neutral B mesons, offers the possibility of determining conclusively whether CP violation is part and parcel of the Standard Model with three generations of quarks and leptons. Alternatively, the authors may discover that CP violation lies outside the present framework. In this paper the authors briefly describe the physics reach of the SLAC/LBL/LLNL Asymmetric B-Factory, the progress on the machine design and construction, the progress on the detector design, and the schedule to complete both projects

  15. Qualitative case study methodology in nursing research: an integrative review.

    Science.gov (United States)

    Anthony, Susan; Jack, Susan

    2009-06-01

    This paper is a report of an integrative review conducted to critically analyse the contemporary use of qualitative case study methodology in nursing research. Increasing complexity in health care and increasing use of case study in nursing research support the need for current examination of this methodology. In 2007, a search for case study research (published 2005-2007) indexed in the CINAHL, MEDLINE, EMBASE, PsychINFO, Sociological Abstracts and SCOPUS databases was conducted. A sample of 42 case study research papers met the inclusion criteria. Whittemore and Knafl's integrative review method guided the analysis. Confusion exists about the name, nature and use of case study. This methodology, including terminology and concepts, is often invisible in qualitative study titles and abstracts. Case study is an exclusive methodology and an adjunct to exploring particular aspects of phenomena under investigation in larger or mixed-methods studies. A high quality of case study exists in nursing research. Judicious selection and diligent application of literature review methods promote the development of nursing science. Case study is becoming entrenched in the nursing research lexicon as a well-accepted methodology for studying phenomena in health and social care, and its growing use warrants continued appraisal to promote nursing knowledge development. Attention to all case study elements, process and publication is important in promoting authenticity, methodological quality and visibility.

  16. Ethical considerations in sexual health research: A narrative review

    Directory of Open Access Journals (Sweden)

    Maryam Shirmohammadi

    2018-01-01

    Full Text Available Background: There is an assumption that sexual health research has great influence on the quality of human life through elevating sexual health standards, and their results will eliminate the burden of sexual health challenges on family relationships. The aim of this study was to review ethical considerations in sexual health research. Materials and Methods: This narrative review was conducted between January 1990 and December 2017 based on the five-step approach of York University. The keywords used to search for the studies included ethical issues, research, sexual health, reproductive health, and sensitive topics. The language of the literatures was English and the search process was performed on PubMed, Elsevier, Ovid, Springer, Google Scholar, ResearchGate, SAGE Publishing, ProQuest, WHO website, Kinsey Confidential, and Worldsexology. Results: After assessing the quality and eligibility of 94 articles, 13 were selected. The results of the present study showed that the most important ethical considerations were protecting the confidentiality and privacy of participants, obtaining informed consent, and paying attention to vulnerable people. Conclusions: The review of literature exhibited several considerations that sexual health researchers are faced with. In order to manage these considerations, the researcher should have sufficient understanding of them. The important matter is that strategies to manage these challenges should be completely rational and practical according to each context. These strategies can also be applied in other societies with great similarities in their context.

    Fleurence, Rachael L; Forsythe, Laura P; Lauer, Michael; Rotter, Jason; Ioannidis, John P A; Beal, Anne; Frank, Lori; Selby, Joseph V

    2014-07-15

    The inaugural round of merit review for the Patient-Centered Outcomes Research Institute (PCORI) in November 2012 included patients and other stakeholders, as well as scientists. This article examines relationships among scores of the 3 reviewer types, changes in scoring after in-person discussion, and the effect of inclusion of patient and stakeholder reviewers on the review process. In the first phase, 363 scientists scored 480 applications. In the second phase, 59 scientists, 21 patients, and 31 stakeholders provided a "prediscussion" score and a final "postdiscussion" score after an in-person meeting for applications. Bland-Altman plots were used to characterize levels of agreement among and within reviewer types before and after discussion. Before discussion, there was little agreement among average scores given by the 4 lead scientific reviewers and patient and stakeholder reviewers. After discussion, the 4 primary reviewers showed mild convergence in their scores, and the 21-member panel came to a much stronger agreement. Of the 25 awards with the best (and lowest) scores after phase 2, only 13 had ranked in the top 25 after the phase 1 review by scientists. Five percent of the 480 proposals submitted were funded. The authors conclude that patient and stakeholder reviewers brought different perspectives to the review process but that in-person discussion led to closer agreement among reviewer types. It is not yet known whether these conclusions are generalizable to future rounds of peer review. Future work would benefit from additional data collection for evaluation purposes and from long-term evaluation of the effect on the funded research.

  19. Adolescents and Pornography: A Review of 20 Years of Research.

    Science.gov (United States)

    Peter, Jochen; Valkenburg, Patti M

    2016-01-01

    The goal of this review was to systematize empirical research that was published in peer-reviewed English-language journals between 1995 and 2015 on the prevalence, predictors, and implications of adolescents' use of pornography. This research showed that adolescents use pornography, but prevalence rates varied greatly. Adolescents who used pornography more frequently were male, at a more advanced pubertal stage, sensation seekers, and had weak or troubled family relations. Pornography use was associated with more permissive sexual attitudes and tended to be linked with stronger gender-stereotypical sexual beliefs. It also seemed to be related to the occurrence of sexual intercourse, greater experience with casual sex behavior, and more sexual aggression, both in terms of perpetration and victimization. The findings of this review need to be seen against the background of various methodological and theoretical shortcomings, as well as several biases in the literature, which currently precludes internally valid causal conclusions about effects of pornography on adolescents.

    Mª Luz Rodríguez Palmero

    2000-09-01

    Full Text Available This review complements another one done by the same author, in 1997, regarding the role of comprehending the concept of cell in the learning of Biology. In addition, some general papers on science education that provide a better understanding of research approaches used in the investigation of this topic have been included. The reviewed papers have been organized into categories according to the object of study, the relevance assigned to the cell concept, and the framework of analysis. The review shows that the concept of cell is very important in the biological conceptualization, however, it also shows the need of additional research on this matter, from theoretical frameworks that pay more attention to the psychological level, in order to provide some guidance to improve the teaching and learning processes of the biological content that presupose the comprehension of living beings.

    Energy Technology Data Exchange (ETDEWEB)

    2007-07-01

    This 2006 issue of the NREL Research Review again reveals just how vital and diverse our research portfolio has become. Our feature story looks at how our move to embrace the tenants of "translational research" is strengthening our ability to meet the nation's energy goals. By closing the gap between basic science and applied research and development (R&D)--and focusing a bright light on the valuable end uses of our work--translational research promises to shorten the time it takes to push new technology off the lab bench and into the marketplace. This issue also examines our research into fuels of the future and our computer modeling of wind power deployment, both of which point out the real-world benefits of our work.

    Full Text Available Over the past decade work engagement has gained both business and academia attention. With growing number of studies and meta-analyses the concept of work engagement is one of the pillars of positive work and organizational psychology. This systematic review presents the current state of research on work engagement in Poland. Results confirmed that work-engagement studies have not yet reached the threshold to conduct meta-analysis. The review of measurement methods and synthesis of findings allows to identify strengths and gaps in Polish studies. Discussion of limitations and biases in current research is accompanied with urge to overcome them and develop thriving stream of research on work engagement.

    Vitale, Anne

    2007-01-01

    Reiki touch therapy is a complementary biofield energy therapy that involves the use of hands to help strengthen the body's ability to heal. There is growing interest among nurses to use Reiki in patient care and as a self-care treatment, however, with little supportive empirical research and evidence to substantiate these practices. The purpose of this integrative review is to begin the systematic process of evaluating the findings of published Reiki research. Selected investigations using Reiki for effects on stress, relaxation, depression, pain, and wound healing management, among others is reviewed and summarized. A summary of Reiki studies table illustrates the study descriptions and Reiki treatment protocols specified in the investigations. Synthesis of findings for clinical practice and implications for future research are explored.

    Full Text Available The fast-fashion (FF is considered an approach and phenomenon of global influence that suit the requirements of a constantly changing and demanding market, since it is a business model resulting of a mixture of fast manufacturing, flexibility, low cost and agile retail approaches. Within this context, this research by a systematic literature review seeks to answer how the FF has been addressed in scientific studies published until the year 2013. Through the review, a total of 82 texts was analysed, among them articles, dissertations and theses. The research method employed is characterized as descriptive, regarding the objectives, and as qualitative and quantitative, on the approach. After conducting the classification of the material, it was possible to understand the state-of-the-art, and thus set a holistic concept and the appropriate term for the FF. As well as propose a research agenda with new approaches for future studies within the relevant topic.

    Masters, Kevin S; Spielmans, Glen I

    2007-08-01

    This article reviews the empirical research on prayer and health and offers a research agenda to guide future studies. Though many people practice prayer and believe it affects their health, scientific evidence is limited. In keeping with a general increase in interest in spirituality and complementary and alternative treatments, prayer has garnered attention among a growing number of behavioral scientists. The effects of distant intercessory prayer are examined by meta-analysis and it is concluded that no discernable effects can be found. The literature regarding frequency of prayer, content of prayer, and prayer as a coping strategy is subsequently reviewed. Suggestions for future research include the conduct of experimental studies based on conceptual models that include precise operationally defined constructs, longitudinal investigations with proper measure of control variables, and increased use of ecological momentary assessment techniques.

    Schaps, E; Churgin, S; Palley, C S; Takata, B; Cohen, A Y

    1980-07-01

    This article reviews 35 drug abuse prevention program evaluations employing drug-specific outcome measures. Many of these evaluations assessed the effects of "new generation" prevention strategies: affective, peer-oriented, and multidimensional approaches. Only 14 studies evaluated purely informational programs. Evaluations were analyzed to ascertain (1) characteristics of the programs under study, (2) characteristics of the research designs, and (3) patterns among findings. This review provides some evidence that the newer prevention strategies may produce more positive and fewer negative outcomes than did older drug information approaches. Over 70% of the programs using the newer strategies produced some positive effects; only 29% showed negative effects. In contrast, 46% of informational programs showed positive effects; 46% showed negative effects. These findings must be approached with great caution, since the research was frequently scientifically inadequate, and since rigor of research was negatively correlated with intensity and duration of program services.

    2006-06-01

    DESPITE CLAIMS THAT RESEARCH-ETHICS review is changing or discouraging social research, there are no studies that have tested this assumption. Examining Canadian Master's theses in anthropology between 1995 and 2004, this paper explores the extent to which the theses represent a change in number, topic, or methodology in relation to formal ethicsreview guidelines that came into force in Canada in 2001. ProQuest Digital Dissertations reveals that the number of theses has increased, and that there has not been a noticeable shift from research involving humans to research based on archival data, or theoretical or review theses. However, there has been a very significant increase in research that is called ethnography, but that relies exclusively on interviews. Possible reasons for the halving of percent of ethnographic or participantobservation research are explored.

    Big data and cutting-edge analytic methods in nursing research challenge nurse scientists to extend the data sources and analytic methods used for discovering and translating knowledge. The purpose of this study was to identify, analyze, and synthesize exemplars of big data nursing research applied to practice and disseminated in key nursing informatics, general biomedical informatics, and nursing research journals. A literature review of studies published between 2009 and 2015. There were 650 journal articles identified in 17 key nursing informatics, general biomedical informatics, and nursing research journals in the Web of Science database. After screening for inclusion and exclusion criteria, 17 studies published in 18 articles were identified as big data nursing research applied to practice. Nurses clearly are beginning to conduct big data research applied to practice. These studies represent multiple data sources and settings. Although numerous analytic methods were used, the fundamental issue remains to define the types of analyses consistent with big data analytic methods. There are needs to increase the visibility of big data and data science research conducted by nurse scientists, further examine the use of state of the science in data analytics, and continue to expand the availability and use of a variety of scientific, governmental, and industry data resources. A major implication of this literature review is whether nursing faculty and preparation of future scientists (PhD programs) are prepared for big data and data science. Copyright © 2016 Elsevier Inc.

    This document addresses the concern raised in the Savannah River Site (SRS) Acceptance Criteria (Reference 1, Section 6.a.3) about receiving an item that is over batched by 1.0 kg of fissile materials. This document shows that the occurrence of this is incredible. Some of the Department of Energy Standard 3013 (DOE-STD-3013) requirements are described in Section 2.1. The SRS requirement is discussed in Section 2.2. Section 2.3 describes the way fissile materials are handled in the Lawrence Livermore National Laboratory (LLNL) Plutonium Facility (B332). Based on the material handling discussed in Section 2.3, there are only three errors that could result in a shipping container being over batched. These are: incorrect measurement of the item, selecting the wrong item to package, and packaging two items into a single shipping container. The analysis in Section 3 shows that the first two events are incredible because of the controls that exist at LLNL. The third event is physically impossible. Therefore, it is incredible for an item to be shipped to SRS that is more than 1.0 kg of fissile materials over batched

    Lawrence Livermore National Laboratory (LLNL) and the U.S. Department of Energy, Oakland Field Office (DOE/OAK), are participating in a pilot program to evaluate the process to develop necessary and sufficient sets of standards for contractor activities. This concept of contractor and DOE jointly and locally deciding on what constitutes the set of standards that are necessary and sufficient to perform work safely and in compliance with federal, state, and local regulations, grew out of DOE's Department Standards Committee (Criteria for the Department's Standards Program, August 1994, DOE/EH/-0416). We have chosen radioactive waste management activities as the pilot program at LLNL. This pilot includes low-level radioactive waste, transuranic (TRU) waste, and the radioactive component of low-level and TRU mixed wastes. Guidance for the development and implementation of the necessary and sufficient set of standards is provided in open-quotes The Department of Energy Closure Process for Necessary and Sufficient Sets of Standards,close quotes March 27, 1995 (draft)

    The existing Lawrence Livermore National Laboratory (LLNL) Site 300 drinking water system operation schematic is shown in Figures 1 and 2 below. The sources of water are from two Site 300 wells (Well #18 and Well #20) and San Francisco Public Utilities Commission (SFPUC) Hetch-Hetchy water through the Thomas shaft pumping station. Currently, Well #20 with 300 gallons per minute (gpm) pump capacity is the primary source of well water used during the months of September through July, while Well #18 with 225 gpm pump capacity is the source of well water for the month of August. The well water is chlorinated using sodium hypochlorite to provide required residual chlorine throughout Site 300. Well water chlorination is covered in the Lawrence Livermore National Laboratory Experimental Test Site (Site 300) Chlorination Plan (“the Chlorination Plan”; LLNL-TR-642903; current version dated August 2013). The third source of water is the SFPUC Hetch-Hetchy Water System through the Thomas shaft facility with a 150 gpm pump capacity. At the Thomas shaft station the pumped water is treated through SFPUC-owned and operated ultraviolet (UV) reactor disinfection units on its way to Site 300. The Thomas Shaft Hetch- Hetchy water line is connected to the Site 300 water system through the line common to Well pumps #18 and #20 at valve box #1.

    To review the use of mixed-methods research in nursing with a particular focus on the extent to which current practice informs nurse researchers. It also aimed to highlight gaps in current knowledge, understanding and reporting of this type of research. Mixed-methods research is becoming increasingly popular among nurses and healthcare professionals. Emergent findings from this type of research are very useful for nurses in practice. The combination of both quantitative and qualitative methods provides a scientific base for practice but also richness from the qualitative enquiry. However, at the same time mixed-methods research is underdeveloped. This study identified mixed-methods research papers and critically evaluated their usefulness for research practice. To support the analysis, we performed a two-stage search using CINAHL to find papers with titles that included the key term 'mixed method'. An analysis of studies that used mixed-methods research revealed some inconsistencies in application and reporting. Attempts to use two distinct research methods in these studies often meant that one or both aspects had limitations. Overall methods were applied in a less rigorous way. This has implications for providing somewhat limited direction for novice researchers. There is also potential for application of evidence in healthcare practice that limited validity. This study highlights current gaps in knowledge, understanding and reporting of mixed-methods research. While these methods are useful to gain insight into clinical problems nurses lack guidance with this type of research. This study revealed that the guidance provided by current mixed-methods research is inconsistent and incomplete and this compounds the lack of available direction. There is an urgent need to develop robust guidelines for using mixed-methods research so that findings may be critically implemented in practice. © 2016 John Wiley & Sons Ltd.

    McCann's et al. (2012) research study revealed several adverse effects that depression can have on young adults. The findings showed that depression in young adults can be life-threatening if not treated (McCann et al., 2012). One implication for evidenced-based nursing practice would be to educate family and friends on the signs of depression and how to respond to them. A suggestion for future research would be to conduct a study showing the effectiveness of different treatment methods (e.g., therapy, medications) on adolescent depression.

    Full Text Available Research is a scientific quest to find answers to certain questions. It makes us think with curiosity and wonderment about how to make something better. Research contributes in a major way to the development and maintenance of health and health care systems. Qualitative research is concerned with qualitative phenomena and includes subjective assessment of attitudes, opinions, and behavior. It is especially important in the behavioral sciences where the aim is to discover the underlying motives of human behavior. The critical incident technique (CIT is a well-established qualitative research tool used in many areas of health sciences including nursing, medicine, dentistry, and their respective education systems. This technique is described as consisting of “a set of procedures for collecting direct observations of human behavior in such a way as to facilitate their potential usefulness in solving practical problems.” This review gives a gist of CIT and its application in different aspects of dental research.

    Research on emotion and pain has burgeoned. We review the last decade's literature, focusing on links between emotional processes and persistent pain. Neurobiological research documents the neural processes that distinguish affective from sensory pain dimensions, link emotion and pain, and generate central nervous system pain sensitization. Psychological research demonstrates that greater pain is related to emotional stress and limited emotional awareness, expression, and processing. Social research shows the potential importance of emotional communication, empathy, attachment, and rejection. Emotions are integral to the conceptualization, assessment, and treatment of persistent pain. Research should clarify when to eliminate or attenuate negative emotions, and when to access, experience, and express them. Theory and practice should integrate emotion into cognitive-behavioral models of persistent pain. © 2011 Wiley Periodicals, Inc.

  1. Characteristics of a productive research environment: literature review.

    Bland, C J; Ruffin, M T

    1992-06-01

    What environmental factors stimulate and maintain research productivity? To answer this question, the authors conducted an extensive review of articles and books on research productivity published from the mid-1960s through 1990. This review revealed that a consistent set of 12 characteristics was found in research-conducive environments: (1) clear goals that serve a coordinating function, (2) research emphasis, (3) distinctive culture, (4) positive group climate, (5) assertive participative governance, (6) decentralized organization, (7) frequent communication, (8) accessible resources, particularly human, (9) sufficient size, age, and diversity of the research group, (10) appropriate rewards, (11) concentration on recruitment and selection, and (12) leadership with research expertise and skill in both initiating appropriate organizational structure and using participatory management practices. Some of these characteristics are not surprising, although some findings were unexpected, such as that participative governance correlated consistently with research productivity. The differential impact of each of these 12 characteristics is unclear. It is clear, however, that the leader has a disproportionate impact through his or her influence on all of the other characteristics. Yet, an overarching feature of these characteristics is their interdependency. These factors do not operate in research groups as isolated characteristics. Rather, they are like fine threads of a whole fabric: individual, yet when interwoven, providing a strong, supportive, and stimulating backdrop for the researcher. The authors conclude that while at a distance the productive research enterprise looks like a highly robust entity, upon closer inspection it is revealed to be a delicate structure highly dependent on the existence and effective working of numerous individual, organizational, and leadership characteristics.

    Patient recruitment in primary care research is often a protracted and frustrating process, affecting project timeframes, budget and the dissemination of research findings. Yet, clear guidance on patient recruitment strategies in primary care research is limited. This paper addresses this issue through a systematic review. Articles were sourced from five academic databases - AustHealth, CINAHL, the Cochrane Methodology Group, EMBASE and PubMed/Medline; grey literature was also sourced from an academic library and the Primary Healthcare Research & Information Service (PHCRIS) website. Two reviewers independently screened the articles using the following criteria: (1) published in English, (2) reported empirical research, (3) focused on interventions designed to increase patient recruitment in primary care settings, and (4) reported patient recruitment in primary care settings. Sixty-six articles met the inclusion criteria. Of these, 23 specifically focused on recruitment strategies and included randomised trials (n = 7), systematic reviews (n = 8) and qualitative studies (n = 8). Of the remaining articles, 30 evaluated recruitment strategies, while 13 addressed the value of recruitment strategies using descriptive statistics and/or qualitative data. Among the 66 articles, primary care chiefly included general practice (n = 30); nursing and allied health services, multiple settings, as well as other community settings (n = 30); and pharmacy (n = 6). Effective recruitment strategies included the involvement of a discipline champion, simple patient eligibility criteria, patient incentives and organisational strategies that reduce practitioner workload. The most effective recruitment in primary care research requires practitioner involvement. The active participation of primary care practitioners in both the design and conduct of research helps to identify strategies that are congruent with the context in which patient care is delivered. This is reported to be the

    2015-11-01

    The aim of this study was to outline a conceptual framework for understanding driving style and, on this basis, review the state-of-the-art research on driving styles in relation to road safety. Previous research has indicated a relationship between the driving styles adopted by drivers and their crash involvement. However, a comprehensive literature review of driving style research is lacking. A systematic literature search was conducted, including empirical, theoretical, and methodological research, on driving styles related to road safety. A conceptual framework was proposed whereby driving styles are viewed in terms of driving habits established as a result of individual dispositions as well as social norms and cultural values. Moreover, a general scheme for categorizing and operationalizing driving styles was suggested. On this basis, existing literature on driving styles and indicators was reviewed. Links between driving styles and road safety were identified and individual and sociocultural factors influencing driving style were reviewed. Existing studies have addressed a wide variety of driving styles, and there is an acute need for a unifying conceptual framework in order to synthesize these results and make useful generalizations. There is a considerable potential for increasing road safety by means of behavior modification. Naturalistic driving observations represent particularly promising approaches to future research on driving styles. Knowledge about driving styles can be applied in programs for modifying driver behavior and in the context of usage-based insurance. It may also be used as a means for driver identification and for the development of driver assistance systems. © 2015, Human Factors and Ergonomics Society.

    2016-06-01

    A literature review of 16 papers on occupational injury research in Malaysia published during a 13-year period from 2000-2013 was carried out. The objective of this review and article selection was based on relevance to the research theme and mention of areas for future research. Most of the publications have focused on descriptive epidemiology, management practices, worker's knowledge, attitude, training, and rehabilitation services. The transportation, agriculture and construction sectors were found to be the most hazardous sectors and would benefit the most from Occupational Safety & Health (OSH) research and interventions. There is a strong need to develop a national injury surveillance system and also a mechanism to ensure adherence to the Occupational Safety & Health Act(OSHA) 1994. Detailed description and identification of risk factors for occupational injury in the environment, including machinery and equipment used was generally lacking. Future research on occupational injury should focus on surveillance to determine the magnitude of occupational injuries, determination of risk factors, identifying costeffective interventions (such as enforcement of OSHA regulations), and assessment of rehabilitation services. Relevant government agencies, universities, corporate sector and occupational safety organizations need to play a proactive role in identifying priority areas and research capacity building. Funding for occupational injury should be commensurate with the magnitude of the problem.

    International maritime health has largely developed within the sphere of occupational health services and international health problems. We reviewed publications in the journal International Maritime Health from 2000 to 2010 to establish the coverage of the journal and the scope of research in maritime health. We identified six thematic categories: healthcare access, delivery and integration; telehealth; non-communicable diseases and physical health problems; communicable diseases; psychological functioning and health; and safety-related issues. We describe the research within these themes and report on their publication prominence. We also analyse the research in terms of its geographical focus, the population groups addressed and the research methodologies used. We suggest a broadening of maritime research to include randomised controlled trials, longitudinal studies and more qualitative research; more research addressing the context for non-European seafarers; and research on seafarers spouses and family supports and obligations. We also recommend more research on psychosocial and cultural issues and on telehealth, as well as the development of a stronger systems perspective for promoting maritime health.

    Full Text Available Depression in adolescents is a multicausal phenomenon and a predictor of social problems and other disorders. Thus, it is considered a public health problem. This investigation aims to systematically review the characteristics of the scientific articles about depression in Peruvian adolescents published in Peruvian and non-Peruvian journals. The search was performed in the databases of SciELO, Latindex, Redalyc, Scopus, PubMed, and through Google, using a combination of keywords related to the construct, the sample and its origin. The unit of analysis consisted of 21 articles. The reviewed articles showed inconsistency in the reporting and bibliographic support of the research designs, sampling procedures, psychometric properties of the instruments, instruments used to assess the construct which were not evaluated in our context, and cut-off points obtained in other countries’ samples. Therefore, we can state that the reviewed articles do not fully comply with the publication standards proposed by the American Psychological Association.

  8. A critical review of published research literature reviews on nursing and healthcare ageism.

    To establish how common and impactful nursing and healthcare ageism is and whether proven interventions or prevention methods exist. Ageism has been a concern since 1969 when it was first introduced as a concept for social reform. As ageism has been linked to lower quality health services and reduced health care access, it is imperative that healthcare and nursing ageism is prevented or identified and reduced or eliminated. A qualitative narrative review of published research literature reviews using a scoping design to map all published reviews was undertaken. The EBSCO Discovery Service (providing access to articles in 271 databases, including MEDLINE and CINAHL) and Directory of Open Access Journals (providing access to over 9,000 open access journals) were used to find review articles. Using predetermined inclusion and exclusion criteria, and limited by English language and peer-review publications, 12 eligible reviews were identified and information from them was systematically identified, assessed and synthesised. The 12 reviews did not provide clear and convincing information to determine how common and impactful nursing or healthcare ageism is, nor what can best be done to prevent or address it. Although each review had value since research literature was collected and discussed on nursing or healthcare ageism, the array of literature search and analysis methods, and diversity in conclusions reached about the evidence is highly problematic. Research literature reviews offering a more balanced perspective and demonstrating greater care in finding and using quality evidence are needed. At this point in time, there is no clear understanding of how widespread and impactful nursing or healthcare ageism is, and what can best be done to prevent or address it. Nurses need to be aware that ageism may be common and impactful, and guard against it. © 2017 John Wiley & Sons Ltd.

  9. Russian MINATOM nuclear safety research strategic plan. An international review

    International Nuclear Information System (INIS)

    1999-03-01

    The 'Safety Research Strategic Plan for Russian Nuclear Power Plants' was published in draft form at the Russian International Nuclear Safety Centre (RINSC) by a working group of fifteen senior Russian experts. The Plan consists of 12 chapters, each addressing a specific technical area and containing a number of proposed research programmes and projects to advance the state-of-knowledge in that area. In part because a strong Recommendation to undertake such a Plan was made by the 1998 OECD/NEA study, the OECD Nuclear Energy Agency was asked by the Director of RINSC and the Director of USINSC to organize an international review of the Plan when the English-language version became available in October, 1998. This report represents the results of that review. (R.P.)

    A PSR for a research reactor became a legal requirement as the Nuclear Safety Act was amended and came into effect in 2014. This paper describes the current status and methodology of the first Periodic Safety Review (PSR) of HANARO that is being performed. The legal requirements, work plan, and process of implementing a PSR are described. Because this is the first PSR for a research reactor, it is our understating that the operating organization and regulatory body should communicate well with each other to complete the PSR in a timely manner. The first PSR of HANARO is under way. In order to achieve a successful result, activities of the operation organization such as scheduling, maintaining consistency in input data for review, and reviewing the PSR reports that will require intensive resources should be well planned. This means the operating organization needs to incorporate appropriate measures to ensure the transfer of knowledge and expertise arising from the PSR via a contractor to the operation organization. It is desirable for the Regulatory Body to be involved in all stage of the PSR to prevent any waste of resources and minimize the potential for a reworking of the PSR and the need for an additional assessment and review as recommended by foreign experts.

  12. A systematic literature review of resilience engineering: Research areas and a research agenda proposal

    International Nuclear Information System (INIS)

    Righi, Angela Weber; Saurin, Tarcisio Abreu; Wachs, Priscila

    2015-01-01

    Resilience engineering (RE) has been advocated as a new safety management paradigm, compatible with the nature of complex socio-technical systems. This study aims to identify the research areas and to propose a research agenda for RE, based on a systematic literature review that encompasses 237 studies from 2006 to 2014. Six research areas are identified: theory of RE; identification and classification of resilience; safety management tools; analysis of accidents; risk assessment; and training. The area “theory of RE” accounted for 52% of the studies, and it indicates that research has emphasized the description of how resilient performance occurs. The proposal for a research agenda is focused on: refining key constructs; positioning RE in relation to other theories; exploring other research strategies in addition to case-based studies; investigating barriers for implementing RE; and balancing the importance on describing and understanding resilience with the emphasis on the design of resilient systems, and the evaluation of these designs. - Highlights: • Six research areas on RE are identified. • A research agenda for RE is proposed. • RE research is mostly descriptive and based on case studies. • Design science is suggested as a research strategy for RE. • Five domains account for 75% of the reviewed studies

    2012-01-30

    Given the global concern about the status of elasmobranch fishes, the paucity of information on elasmobranchs in the Red Sea is worrisome. Management of elasmobranchs in areas other than the Red Sea has been helped by research on population ecology, reproductive biology and resource partitioning, subjects that are virtually absent in the Red Sea elasmobranch literature. This review provides the first comprehensive summary of elasmobranch biology in the Red Sea with the aim of facilitating research in a region that remains remarkably under-studied. © 2012 The Authors.

    2015-08-01

    To summarise the published research on teenage pregnancy in Malaysia, discuss the impact of the findings on clinical practice, and identify gaps in teenage pregnancy research in Malaysia. There were 31 articles related to teen pregnancy found after searching a database dedicated to indexing all original clinical research data published in Malaysia from year 2000 to 2014. Twenty-seven articles (including reports from the National Obstetrics Registry) were selected and reviewed on the basis of clinical relevance and future research implications. This literature review has been divided into eight sections: epidemiology, age at first marriage, adolescent fertility rate, unmarried childbearing, risk factors, maternal risks and neonatal outcome, future plan after delivery, and contraceptive use. More than 19,000 births to teenage mothers were recorded each year between 2009 and 2011. Adolescent fertility rates were recorded at 6 births per 1000 women ages 15-19 years in 2013. Many of these births were from unwed pregnancies, which accounted for 1.99% of total deliveries. A majority of young mothers were willing to take care of their baby, although some of them planned to put their baby up for adoption. Risk factors for teenage pregnancy were found to be similar to those published in studies worldwide. More research is needed to better understand the issue of teen pregnancy. For the best results, collaborative studies among nationwide hospitals and institutions should be the way forward.

  18. Research Review: Gender identity in youth: treatment paradigms and controversies.

    Turban, Jack L; Ehrensaft, Diane

    2017-10-26

    Pediatric gender identity has gained increased attention over the past several years in the popular media, political arena, and medical literature. This article reviews terminology in this evolving field, traditional models of gender identity development and their limitations, epidemiology and natural history of cross-gender identification among children and adolescents, co-occurring conditions and behaviors, research into the biological and psychosocial determinants of cross-gender identification, and research into the options regarding and benefits of clinical approaches to gender incongruent youth. Based on a critical review of the extant literature, both theoretical and empirical, that addresses the issue of pediatric gender identity, the authors synthesized what is presently known and what is in need of further research in order to elucidate the developmental trajectory and clinical needs of gender diverse youth. The field of pediatric gender identity has evolved substantially over the past several years. New research suggests that cross-gender identification is prevalent (approximately 1% of youth). These youth suffer disproportionately high rates of anxiety, depression, and suicidality. Although research into the etiology of cross-gender identification is limited, emerging data have shown that affirmative treatment protocols may improve the high rates of mental health difficulties seen among these patients. The field of pediatric gender identity has evolved dramatically. Emerging data suggest that these patients' high rates of anxiety, depression, and suicidality appear to be improved with affirmative protocols, although future longitudinal data are needed. © 2017 Association for Child and Adolescent Mental Health.

    Critical appraisal of clinical evidence promises to help prevent, detect, and address flaws related to study importance, ethics, validity, applicability, and reporting. These research issues are of growing concern. The purpose of this scoping review is to survey the current literature on evidence appraisal to develop a conceptual framework and an informatics research agenda. We conducted an iterative literature search of Medline for discussion or research on the critical appraisal of clinical evidence. After title and abstract review, 121 articles were included in the analysis. We performed qualitative thematic analysis to describe the evidence appraisal architecture and its issues and opportunities. From this analysis, we derived a conceptual framework and an informatics research agenda. We identified 68 themes in 10 categories. This analysis revealed that the practice of evidence appraisal is quite common but is rarely subjected to documentation, organization, validation, integration, or uptake. This is related to underdeveloped tools, scant incentives, and insufficient acquisition of appraisal data and transformation of the data into usable knowledge. The gaps in acquiring appraisal data, transforming the data into actionable information and knowledge, and ensuring its dissemination and adoption can be addressed with proven informatics approaches. Evidence appraisal faces several challenges, but implementing an informatics research agenda would likely help realize the potential of evidence appraisal for improving the rigor and value of clinical evidence. © The Author 2017.

    2016-05-01

    Meaningful child participation in medical research is seen as important. In order to facilitate further development of participatory research, we performed a systematic literature study to describe and assess the available knowledge on participatory methods in pediatric research. A search was executed in five databases: PubMed, CINAHL, PsycINFO, Scopus, and Cochrane. After careful screening of relevant papers, finally 24 documents were included in our analysis. Literature on participatory methods in pediatric research appears generally to be descriptive, whereby high-quality evidence is lacking. Overall, five groups of participatory methods for children could be distinguished: observational, verbal, written, visual, and active methods. The choice for one of these methods should be based on the child's age, on social and demographic characteristics, and on the research objectives. To date, these methods are still solely used for obtaining data, yet they are suitable for conducting meaningful participation. This may result in a successful partnership between children and researchers. Researchers conducting participatory research with children can use this systematic review in order to weigh the current knowledge about the participatory methods presented.

    2013-09-01

    Caffeine is the most commonly used drug in the world. Although consumption of low to moderate doses of caffeine is generally safe, an increasing number of clinical studies are showing that some caffeine users become dependent on the drug and are unable to reduce consumption despite knowledge of recurrent health problems associated with continued use. Thus, the World Health Organization and some health care professionals recognize caffeine dependence as a clinical disorder. In this comprehensive literature review, we summarize published research on the biological evidence for caffeine dependence; we provide a systematic review of the prevalence of caffeine dependence and rates of endorsement of clinically meaningful indicators of distress and functional impairment among habitual caffeine users; we discuss the diagnostic criteria for Caffeine Use Disorder-a condition for further study included in the Diagnostic and Statistical Manual of Mental Disorders ( 5 th ed .); and we outline a research agenda to help guide future clinical, epidemiological, and genetic investigations of caffeine dependence. Numerous controlled laboratory investigations reviewed in this article show that caffeine produces behavioral and physiological effects similar to other drugs of dependence. Moreover, several recent clinical studies indicate that caffeine dependence is a clinically meaningful disorder that affects a nontrivial proportion of caffeine users. Nevertheless, more research is needed to determine the reliability, validity, and prevalence of this clinically important health problem.

    Full Text Available Background: Complementary and alternative medicine is a rapidly growing area of biomedical inquiry. Yoga has emerged in the forefront of holistic medical care due to its long history of linking physical, mental, and spiritual well-being. Research in yoga therapy (YT has associated improved cardiovascular and quality of life (QoL outcomes for the special needs of heart failure (HF patients. Aim: The aim of this study is to review yoga intervention studies on HF patients, discuss proposed mechanisms, and examine yoga's effect on physiological systems that have potential benefits for HF patients. Second, to recommend future research directions to find the most effective delivery methods of yoga to medically stable HF patients. Methods: The authors conducted a systematic review of the medical literature for RCTs involving HF patients as participants in yoga interventions and for studies utilizing mechanistic theories of stretch and new technologies. We examined physical intensity, mechanistic theories, and the use of the latest technologies. Conclusions: Based on the review, there is a need to further explore yoga mechanisms and research options for the delivery of YT. Software apps as exergames developed for use at home and community activity centers may minimize health disparities and increase QoL for HF patients.

    To suggest a behavioural research agenda for patients with end-stage renal disease (ESRD) based on a concise review of seven stages of psychosocial research, a literature review, and current behavioural research in other chronic somatic diseases. Historical behavioural ESRD research was classified. The specialized register of the Cochrane Behavioral Medicine Field was also checked, and additional papers were selected by screening reference lists and related behavioural science journals, to identify promising areas for future research. The top-five topics identified via the literature search pertain to (1) psychological aspects and interventions, (2) adaptation, coping, and depression, (3) exercise, (4) counseling and education, and (5) compliance. 'Illness and treatment beliefs', 'sexuality', 'suicide', 'family support', and 'self-management interventions', were identified on the basis of research in other chronic illnesses as topics for future research. Regarding theory, the Common-Sense Model (CSM) was judged to offer useful theoretical perspectives; regarding methods, qualitative methods can be a valuable addition to quantitative research methods. Illness beliefs, treatment beliefs, and self-management behaviours are promising concepts in the assessment and clinical care of ESRD-patients. Cognitive-behavioural treatments appear to have potential and should be specified and elaborated for specific categories and problems of ESRD-patients. This research agenda is in line with moves towards patient-centred disease-management to improve the quality of medical care for ESRD-patients. (c) 2009 Elsevier Ireland Ltd. All rights reserved.

  5. Different Perspectives on Internationalization Research: A Bibliometric Review

    2015-12-01

    Full Text Available A wealth of research has addressed the internationalization of firms using different theories and conceptual perspectives. This paper examines the extant research on internationalization specifically delving into seven streams of research: Market Power, Evolutionary Model, Internalization & Transaction Cost, Eclectic Paradigm, Resource-Based View, Institutional and International New Ventures & Born Global. Methodologically we conduct a bibliometric review in six leading journals recognized for publishing International Business (IB research, during a forty one year period, from 1970 to 2010. Using citations and co-citations analyses on a sample of 1,459 articles, we sought to better understand the internationalization approaches and how they are interconnected, by examining its growth over time, the most used approaches, the works that have had the greatest impact, and the intellectual interconnections among authors. We conclude that there is no dominant approach in International Business research, albeit the Evolutionary Model has been the most cited - in almost 26% of the extant research, specially the paper– “The internationalization process of the firm: A model of knowledge development and increasing foreign market commitment”, by Johanson and Vahlne (1977. We present a broad discussion and point out limitations and directions for future research.

  6. Reporting of clinical trials: a review of research funders' guidelines

    2008-11-01

    Full Text Available Abstract Background Randomised controlled trials (RCTs represent the gold standard methodological design to evaluate the effectiveness of an intervention in humans but they are subject to bias, including study publication bias and outcome reporting bias. National and international organisations and charities give recommendations for good research practice in relation to RCTs but to date no review of these guidelines has been undertaken with respect to reporting bias. Methods National and international organisations and UK based charities listed on the Association for Medical Research Charities website were contacted in 2007; they were considered eligible for this review if they funded RCTs. Guidelines were obtained and assessed in relation to what was written about trial registration, protocol adherence and trial publication. It was also noted whether any monitoring against these guidelines was undertaken. This information was necessary to discover how much guidance researchers are given on the publication of results, in order to prevent study publication bias and outcome reporting bias. Results Seventeen organisations and 56 charities were eligible of 140 surveyed for this review, although there was no response from 12. Trial registration, protocol adherence, trial publication and monitoring against the guidelines were often explicitly discussed or implicitly referred too. However, only eleven of these organisations or charities mentioned the publication of negative as well as positive outcomes and just three of the organisations specifically stated that the statistical analysis plan should be strictly adhered to and all changes should be reported. Conclusion Our review indicates that there is a need to provide more detailed guidance for those conducting and reporting clinical trials to help prevent the selective reporting of results. Statements found in the guidelines generally refer to publication bias rather than outcome reporting bias

    Well-designed research trials are critical for determining the efficacy and effectiveness of nutrition education interventions. To determine whether behavioral and/or cognition changes can be attributed to an intervention, the experimental design must include a control or comparison condition against which outcomes from the experimental group can be compared. Despite the impact different types of control groups can have on study outcomes, the treatment provided to participants in the control condition has received limited attention in the literature. A systematic review of control groups in nutrition education interventions was conducted to better understand how control conditions are described in peer-reviewed journal articles compared with experimental conditions. To be included in the systematic review, articles had to be indexed in CINAHL, PubMed, PsycINFO, WoS, and/or ERIC and report primary research findings of controlled nutrition education intervention trials conducted in the United States with free-living consumer populations and published in English between January 2005 and December 2015. Key elements extracted during data collection included treatment provided to the experimental and control groups (e.g., overall intervention content, tailoring methods, delivery mode, format, duration, setting, and session descriptions, and procedures for standardizing, fidelity of implementation, and blinding); rationale for control group type selected; sample size and attrition; and theoretical foundation. The search yielded 43 publications; about one-third of these had an inactive control condition, which is considered a weak study design. Nearly two-thirds of reviewed studies had an active control condition considered a stronger research design; however, many failed to report one or more key elements of the intervention, especially for the control condition. None of the experimental and control group treatments were sufficiently detailed to permit replication of the

    2015-12-01

    To examine physician assistant (PA) job satisfaction and identify factors predicting job satisfaction and identify areas of needed research. With a global PA movement underway and a half-century in development, the empirical basis for informing employers of approaches to improve job satisfaction has not received a careful review. A narrative review of empirical research was undertaken to inform stakeholders about PA employment with a goal of improved management. The a priori criteria included published studies that asked PAs about job satisfaction. Articles addressing PA job satisfaction, written in English, were reviewed and categorized according to the Job Characteristics Model. Of 68 publications reviewed, 29 met criteria and were categorized in a Job Characteristics Model. Most studies report a high degree of job satisfaction when autonomy, income, patient responsibility, physician support, and career advancement opportunities are surveyed. Age, sex, specialty, and occupational background are needed to understand the effect on job satisfaction. Quality of studies varies widely. Employers may want to examine their relationships with PAs periodically. The factors of job satisfaction may assist policymakers and health administrators in creating welcoming professional employment environments. The main limitation: no study comprehensively evaluated all the antecedents of job satisfaction. PAs seem to experience job satisfaction supported by low attrition rates and competitive wages. Contributing factors are autonomy, experienced responsibility, pay, and supportive supervising physician. A number of intrinsic rewards derived from the performance of the job within the social environment, along with extrinsic rewards, may contribute to overall job satisfaction. PA job satisfaction research is underdeveloped; investigations should include longitudinal studies, cohort analyses, and economic determinants.

    2017-09-01

    Lesbian, gay, bisexual, and transgender (LGBT) individuals experience more negative health outcomes compared with their heterosexual peers. The health disparities are often related to family and social rejection of the LGBT individuals. Integrated care, and Medical Family Therapy in particular, may aid in addressing the systemic nature of the negative health outcomes. To better understand the current state of the integrated care literature on addressing the health needs of LGBT individuals, a systematic review of the research literature was conducted from January 2000 to January 2016 for articles including integrated health care interventions for LGBT populations. Independent reviewers coded identified articles. Only 8 research articles met criteria for inclusion out of the 2,553 initially identified articles in the search. Results indicated a lack of integrated care research on health care and health needs of LGBT individuals, and none of the articles addressed the use of family or systemic-level interventions. Implications for future research and the need for better education training are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  10. Critical factors for EIA implementation: literature review and research options.

    Zhang, Jie; Kørnøv, Lone; Christensen, Per

    2013-01-15

    After decades of development, the gap between expectations of Environment Impact Assessments (EIA) and their practical performance remains significant. Research has been done to identify the critical factors for an effective implementation of EIA. However, this research, to a large extent, has not been cumulated and analysed comprehensively according to the stages of the EIA process. This paper contributes to the critical review of the literature on EIA implementation and effectiveness by cumulating mainly empirical findings in an implementation theoretical perspective. It focuses on the links between different critical factors and how they relate to different stages in the EIA and thus influence the decision making process. After reviewing 33 refereed journal articles published between 1999 and 2011, we identified 203 notions of critical factors. Of these, 102 related to different stages defined in our comprehensive EIA implementation model, and 101 were identified as general factors related to the whole EIA system. The number of notions of stage factors and general factors is thus about equal. An overlap between stage factors and general factors was found, which demonstrates that critical factors function differently in different cases. The function of the critical factors is complex and it is difficult to determine contingencies and causations. In the sources we examined, there is evidently an imbalance between in-depth empirical research and general knowledge, and the paper offers some suggestions for future research.

    1988-09-01

    On June 14--17, 1988 the participants and invited guests of the Cooperative Program in Kraft Recovery gathered in Charleston, South Carolina, to review progress on four major black liquor research programs being executed at the Institute of Paper Chemistry, the University of Maine, the National Bureau of Standards, and the University of Florida. These programs include: (1) Black Liquor Properties; (2) Black Liquor Droplet Formation; (3) Black Liquor Nozzle Evaluation; and (4) Black Liquor Combustion. In addition to the objectives of previous meetings, this meeting made a direct attempt to gather ideas on how to improve our ability to move from new technology concepts to commercial implementation. Also attached is the agenda for the Charleston meeting. The first two days were involved with updates and reviews of the four major black liquor programs. A half day was spent discussing pathways to implementation and developing thoughts on what industry, DOE and academia could do to facilitate commercial implementation of the research results. This publication is a summary of the presentations made in Charleston and the industry responses to the research work. Readers are cautioned that the contents are in-progress updates on the status of the research and do not represent referred technical papers. Any questions regarding the content should be referred to the principal investigators of the project.

  12. A review of research in low earth orbit propellant collection

    Singh, Lake A.; Walker, Mitchell L. R.

    2015-05-01

    This comprehensive review examines the efforts of previous researchers to develop concepts for propellant-collecting spacecraft, estimate the performance of these systems, and understand the physics involved. Rocket propulsion requires the spacecraft to expend two fundamental quantities: energy and propellant mass. A growing number of spacecraft collect the energy they need to execute propulsive maneuvers in-situ with solar panels. In contrast, every spacecraft using rocket propulsion has carried all of the propellant mass needed for the mission from the ground, which limits the range and mission capabilities. Numerous researchers have explored the concept of collecting propellant mass while in space. These concepts have varied in scale and complexity from chemical ramjets to fusion-driven interstellar vessels. Research into propellant-collecting concepts occurred in distinct eras. During the Cold War, concepts tended to be large, complex, and nuclear powered. After the Cold War, concepts transitioned to solar power sources and more effort has been devoted to detailed analysis of specific components of the propellant-collecting architecture. By detailing the major contributions and limitations of previous work, this review concisely presents the state-of-the-art and outlines five areas for continued research. These areas include air-compatible cathode technology, techniques to improve propellant utilization on atmospheric species, in-space compressor and liquefaction technology, improved hypersonic and hyperthermal free molecular flow inlet designs, and improved understanding of how design parameters affect system performance.

    2010-01-01

    The Space Radiation Standing Review Panel (SRP) met at the NASA Johnson Space Center (JSC) on December 9-11, 2009 to discuss the areas of current and future research targeted by the Space Radiation Program Element (SRPE) of the Human Research Program (HRP). Using evidence-based knowledge as a background for identified risks to astronaut health and performance, NASA had identified gaps in knowledge to address those risks. Ongoing and proposed tasks were presented to address the gaps. The charge to the Space Radiation SRP was to review the gaps, evaluate whether the tasks addressed these gaps and to make recommendations to NASA s HRP Science Management Office regarding the SRP's review. The SRP was requested to evaluate the practicality of the proposed efforts in light of the demands placed on the HRP. Several presentations were made to the SRP during the site visit and the SRP spent sufficient time to address the SRP charge. The SRP made a final debriefing to the HRP Program Scientist, Dr. John B. Charles, on December 11, 2009. The SRP noted that current SRPE strategy is properly science-based and views this as the best assurance of the likelihood that answers to the questions posed as gaps in knowledge can be found, that the uncertainty in risk estimates can be reduced, and that a solid, cost-effective approach to risk reduction solutions is being developed. The current approach of the SRPE, based on the use of carefully focused research solicitations, requiring thorough peer-review and approaches demonstrated to be on the path to answering the NASA strategic questions, addressed to a broad extramural community of qualified scientists, optimally positioned to take advantage of serendipitous discoveries and to leverage scientific advances made elsewhere, is sound and appropriate. The SRP viewed with concern statements by HRP implying that the only science legitimately deserving support should be "applied" or, in some instances that the very term "research" might be

    Pyle, R.V.

    1980-01-01

    The LBL/LLNL negative-ion-based neutral beam development program and status are described. The emphasis has shifted in some details since the first symposium in 1977, but our overall objectives remain the same, namely, the development of megawatt d.c. injection systems. Previous emphasis was on a system in which the negative ions were produced by double charge exchange in sodium vapor. At present, the emphasis is on a self-extraction source in which the negative ions are produced on a biased surface imbedded in a plasma. A one-ampere beam will be accelerated to at least 40 keV next year. Studies of negative-ion formation and interactions help provide a data base for the technology program

    1993-01-01

    We have completed a fifteen year, referenced and documented compilation of more than 15,000 measurements of laser-induced damage thresholds (LIDT) conducted at the Lawrence Livermore National Laboratory (LLNL). These measurements cover the spectrum from 248 to 1064 nm with pulse durations ranging from < 1 ns to 65 ns and at pulse-repetition frequencies (PRF) from single shots to 6.3 kHz. We emphasize the changes in LIDTs during the past two years since we last summarized our database. We relate these results to earlier data concentrating on improvements in processing methods, materials, and conditioning techniques. In particular, we highlight the current status of anti-reflective (AR) coatings, high reflectors (HR), polarizers, and frequency-conversion crystals used primarily at 355 nm and 1064 nm

    2005-01-01

    We describe an experiment for production of high harmonic x-ray radiation from Thomson backscattering of an ultra-short high power density laser by a relativistic electron beam at the PLEIADES facility at LLNL. In this scenario, electrons execute a “figure-8” motion under the influence of the high-intensity laser field, where the constant characterizing the field strength is expected to exceed unity: $aL=e*EL/m*c*ωL ≥ 1$. With large $aL$ this motion produces high harmonic x-ray radiation and significant broadening of the spectral peaks. This paper is intended to give a layout of the PLEIADES experiment, along with progress towards experimental goals.

    1985-06-01

    A review of techniques and technology pertaining to the movement of ground water, solutes/radionuclides and heat through porous and fractured media has been conducted. The theory describing each of these processes has been presented in terms of their partial differential equations. The equations serve as the basis for the identification of processes. These parameters have been discussed in detail with regards to their importance in controlling the overall transport processes. A hypothetical research program has been assembled for the purpose of illustrating the hydrogeologic methods and research techniques applicable to site characterization studies. Areas where the current state of the art is lacking have been identified and the necessary research has been recommended. 103 refs

  20. Public health workforce research in review: a 25-year retrospective.

    Hilliard, Tracy M; Boulton, Matthew L

    2012-05-01

    The Robert Wood Johnson Foundation commissioned a systematic review of public health workforce literature in fall 2010. This paper reviews public health workforce articles published from 1985 to 2010 that support development of a public health workforce research agenda, and address four public health workforce research themes: (1) diversity; (2) recruitment, retention, separation, and retirement; (3) education, training, and credentialing; and (4) pay, promotion, performance, and job satisfaction. PubMed, ERIC, and Web of Science databases were used to search for articles; Google search engine was used to identify gray literature. The study used the following inclusion criteria: (1) articles written in English published in the U.S.; (2) the main theme(s) of the article relate to at least one of the four public health workforce research themes; and (3) the document focuses on the domestic public health workforce. The literature suggests that the U.S. public health workforce is facing several urgent priorities that should be addressed, including: (1) developing an ethnically/racially diverse membership to meet the needs of an increasingly diverse nation; (2) recruiting and retaining highly trained, well-prepared employees, and succession planning to replace retirees; (3) building public health workforce infrastructure while also confronting a major shortage in the public health workforce, through increased education, training, and credentialing; and (4) ensuring competitive salaries, opportunities for career advancement, standards for workplace performance, and fostering organizational cultures which generate high levels of job satisfaction for effective delivery of services. Additional research is needed in all four thematic areas reviewed to develop well-informed, evidence-based strategies for effectively addressing critical issues facing the public health workforce.

  1. Rater cognition: review and integration of research findings.

    2016-05-01

    Given the complexity of competency frameworks, associated skills and abilities, and contexts in which they are to be assessed in competency-based education (CBE), there is an increased reliance on rater judgements when considering trainee performance. This increased dependence on rater-based assessment has led to the emergence of rater cognition as a field of research in health professions education. The topic, however, is often conceptualised and ultimately investigated using many different perspectives and theoretical frameworks. Critically analysing how researchers think about, study and discuss rater cognition or the judgement processes in assessment frameworks may provide meaningful and efficient directions in how the field continues to explore the topic. We conducted a critical and integrative review of the literature to explore common conceptualisations and unified terminology associated with rater cognition research. We identified 1045 articles on rater-based assessment in health professions education using Scorpus, Medline and ERIC and 78 articles were included in our review. We propose a three-phase framework of observation, processing and integration. We situate nine specific mechanisms and sub-mechanisms described across the literature within these phases: (i) generating automatic impressions about the person; (ii) formulating high-level inferences; (iii) focusing on different dimensions of competencies; (iv) categorising through well-developed schemata based on (a) personal concept of competence, (b) comparison with various exemplars and (c) task and context specificity; (v) weighting and synthesising information differently, (vi) producing narrative judgements; and (vii) translating narrative judgements into scales. Our review has allowed us to identify common underlying conceptualisations of observed rater mechanisms and subsequently propose a comprehensive, although complex, framework for the dynamic and contextual nature of the rating process

    Innovation represents a core value of the American Rhinologic Society (ARS), with multiple efforts to promote research in the advancement rhinologic care. We therefore sought to identify trends in extramural sinusitis funding and underutilized sources of support to facilitate future efforts. A systematic review of the National Institutes of Health (NIH) Research Portfolio Online Tools (RePORTER) database (fiscal year 1993 to 2017) was completed with the search strategy: ("chronic sinusitis" OR rhinosinusitis). All identified studies were accepted for review, with comparison to ARS membership rolls to identify studies supported by ARS investigators. Foundation awards were surveyed to identify and characterize additional sources of support. The systematic review identified 958 projects receiving NIH funding, of which 120 remain active. The percentage of sinusitis-related awards and total funding relative to all NIH awards increased over the past 10 years (2006 to 2016) from 0.06% (8 / 9128) and 0.09% ($2,151,152 / $3,358,338,602) to 0.87% (86 / 9540) and 0.90% ($37,201,095 / $4,300,145,614). Among active studies, 9 investigators maintain membership in the ARS and serve as principal investigator or project leader in 12 (10%) studies. ARS investigators received the greatest number of awards from the National Institute on Deafness and Other Communication Disrders (n = 8,66.7%), while only receiving 2.2% of awarded funding from the National Institute of Allergy and Infectious Diseases ($607,500/$26,873,022), the largest source of awards for sinusitis research. Support for sinusitis research is significantly growing, with the largest source of active funding not being fully utilized by members of the ARS. Further efforts to promote funding priorities among extramural sources is necessary to facilitate increased funding for ARS member initiatives. © 2017 ARS-AAOA, LLC.

    The development of our Integrated Actinide Sample Preparation Laboratory (IASPL) commenced in 1998 driven by the need to perform transmission electron microscopy studies on naturally aged plutonium and its alloys looking for the microstructural effects of the radiological decay process (1). Remodeling and construction of a laboratory within the Chemistry and Materials Science Directorate facilities at LLNL was required to turn a standard radiological laboratory into a Radiological Materials Area (RMA) and Radiological Buffer Area (RBA) containing type I, II and III workplaces. Two inert atmosphere dry-train glove boxes with antechambers and entry/exit fumehoods (Figure 1), having a baseline atmosphere of 1 ppm oxygen and 1 ppm water vapor, a utility fumehood and a portable, and a third double-walled enclosure have been installed and commissioned. These capabilities, along with highly trained technical staff, facilitate the safe operation of sample preparation processes and instrumentation, and sample handling while minimizing oxidation or corrosion of the plutonium. In addition, we are currently developing the capability to safely transfer small metallographically prepared samples to a mini-SEM for microstructural imaging and chemical analysis. The gloveboxes continue to be the most crucial element of the laboratory allowing nearly oxide-free sample preparation for a wide variety of LLNL-based characterization experiments, which includes transmission electron microscopy, electron energy loss spectroscopy, optical microscopy, electrical resistivity, ion implantation, X-ray diffraction and absorption, magnetometry, metrological surface measurements, high-pressure diamond anvil cell equation-of-state, phonon dispersion measurements, X-ray absorption and emission spectroscopy, and differential scanning calorimetry.

    Participatory research (PR) is the co-construction of research through partnerships between researchers and people affected by and/or responsible for action on the issues under study. Evaluating the benefits of PR is challenging for a number of reasons: the research topics, methods, and study designs are heterogeneous; the extent of collaborative involvement may vary over the duration of a project and from one project to the next; and partnership activities may generate a complex array of both short- and long-term outcomes. Our review team consisted of a collaboration among researchers and decision makers in public health, research funding, ethics review, and community-engaged scholarship. We identified, selected, and appraised a large-variety sample of primary studies describing PR partnerships, and in each stage, two team members independently reviewed and coded the literature. We used key realist review concepts (middle-range theory, demi-regularity, and context-mechanism-outcome configurations [CMO]) to analyze and synthesize the data, using the PR partnership as the main unit of analysis. From 7,167 abstracts and 591 full-text papers, we distilled for synthesis a final sample of twenty-three PR partnerships described in 276 publications. The link between process and outcome in these partnerships was best explained using the middle-range theory of partnership synergy, which demonstrates how PR can (1) ensure culturally and logistically appropriate research, (2) enhance recruitment capacity, (3) generate professional capacity and competence in stakeholder groups, (4) result in productive conflicts followed by useful negotiation, (5) increase the quality of outputs and outcomes over time, (6) increase the sustainability of project goals beyond funded time frames and during gaps in external funding, and (7) create system changes and new unanticipated projects and activities. Negative examples illustrated why these outcomes were not a guaranteed product of PR

    Behavioral addictions, especially pathological gambling and internet addiction, have become a growing concern in research and health policy. Similarities between behavioral addictions and substance dependency are currently being discussed in the scientific community. Unfortunately the number of scientific studies on pathological gambling and internet addiction is still very low. The estimated prevalence of pathological gambling among the German population is 0.2-0.5%. These numbers are comparable to prevalence rates reported for illegal drug dependency. About 1.5 million people, i.e. 3% of the German population, are believed to be at risk of internet addiction. Therefore, it is important to investigate in more detail the clinical and neuroscientific basis of pathological gambling and internet addiction. In this review we summarize the current status of research regarding pathological gambling and internet addiction and outline possible future research perspectives in the field of neuroimaging and genetics. The aim is to develop a multifactorial and explanatory model which helps to improve the quality of existing therapeutic approaches and prevention strategies. At present, parts of the research are funded by the federal states. The authors of this article, supported by scientific associations, have established a research platform called 'pathological gambling' in which research methods and strategies will be discussed which facilitate the implementation of different studies on pathological gambling.

    Full Text Available The purpose of this study is to describe the volume, topics, and methodological nature of the existing research literature on research data management in academic institutions.We conducted a scoping review by searching forty literature databases encompassing a broad range of disciplines from inception to April 2016. We included all study types and data extracted on study design, discipline, data collection tools, and phase of the research data lifecycle.We included 301 articles plus 10 companion reports after screening 13,002 titles and abstracts and 654 full-text articles. Most articles (85% were published from 2010 onwards and conducted within the sciences (86%. More than three-quarters of the articles (78% reported methods that included interviews, cross-sectional, or case studies. Most articles (68% included the Giving Access to Data phase of the UK Data Archive Research Data Lifecycle that examines activities such as sharing data. When studies were grouped into five dominant groupings (Stakeholder, Data, Library, Tool/Device, and Publication, data quality emerged as an integral element.Most studies relied on self-reports (interviews, surveys or accounts from an observer (case studies and we found few studies that collected empirical evidence on activities amongst data producers, particularly those examining the impact of research data management interventions. As well, fewer studies examined research data management at the early phases of research projects. The quality of all research outputs needs attention, from the application of best practices in research data management studies, to data producers depositing data in repositories for long-term use.

    Concerns about reproducibility and impact of research urge improvement initiatives. Current university ranking systems evaluate and compare universities on measures of academic and research performance. Although often useful for marketing purposes, the value of ranking systems when examining quality and outcomes is unclear. The purpose of this study was to evaluate usefulness of ranking systems and identify opportunities to support research quality and performance improvement. A systematic review of university ranking systems was conducted to investigate research performance and academic quality measures. Eligibility requirements included: inclusion of at least 100 doctoral granting institutions, be currently produced on an ongoing basis and include both global and US universities, publish rank calculation methodology in English and independently calculate ranks. Ranking systems must also include some measures of research outcomes. Indicators were abstracted and contrasted with basic quality improvement requirements. Exploration of aggregation methods, validity of research and academic quality indicators, and suitability for quality improvement within ranking systems were also conducted. A total of 24 ranking systems were identified and 13 eligible ranking systems were evaluated. Six of the 13 rankings are 100% focused on research performance. For those reporting weighting, 76% of the total ranks are attributed to research indicators, with 24% attributed to academic or teaching quality. Seven systems rely on reputation surveys and/or faculty and alumni awards. Rankings influence academic choice yet research performance measures are the most weighted indicators. There are no generally accepted academic quality indicators in ranking systems. No single ranking system provides a comprehensive evaluation of research and academic quality. Utilizing a combined approach of the Leiden, Thomson Reuters Most Innovative Universities, and the SCImago ranking systems may provide

    This article describes a review of the Biomedical Research Units (BRU) scheme, undertaken for the Department of Health. This review was a perceptions audit of senior executives involved in the scheme, and explored what impact they felt the scheme is having on the translational research landscape. More specifically, we investigated whether and how institutional relationships between NHS and academic partners, industry and other health research system players are changing because of the scheme; how the scheme is helping build critical mass in specific priority disease areas; and the effects of any changes on efforts to deliver the broader goals set out in Best Research for Best Health. The views presented are those of study informants only. The information obtained through our interviews suggests that the BRU scheme is significantly helping shape the health research system to pursue translational research and innovation, with the clear goal of realising patient benefit. The BRUs are already contributing to observable changes in institutional relationships between the NHS and academic partners: trusts and medical schools are collaborating more closely than in the past, have signed up to the same vision of translational research from bench to bedside, and are managing and governing targeted research resources more professionally and transparently than in the past. There is also a stronger emphasis on engaging industry and more strategic thinking about strengthening regional and national collaboration with other hospital trusts, PCTs, research organisations, networks and development agencies. The scheme is also transforming capacity building in the health research system. This includes (i) developing and modernising facilities and equipment for translation; (ii) building a critical mass of human resources through recruitment and training, as well as improving retention of existing expertise; and (iii) helping ensure a steady flow of funds needed to sustain research

    2014-01-01

    This paper presents the findings of a systematic review of scholarly publications that report empirical findings from studies of environmentally-related international migration. There exists a small, but growing accumulation of empirical studies that consider environmentally-linked migration that spans international borders. These studies provide useful evidence for scholars and policymakers in understanding how environmental factors interact with political, economic and social factors to influence migration behavior and outcomes that are specific to international movements of people, in highlighting promising future research directions, and in raising important considerations for international policymaking. Our review identifies countries of migrant origin and destination that have so far been the subject of empirical research, the environmental factors believed to have influenced these migrations, the interactions of environmental and non-environmental factors as well as the role of context in influencing migration behavior, and the types of methods used by researchers. In reporting our findings, we identify the strengths and challenges associated with the main empirical approaches, highlight significant gaps and future opportunities for empirical work, and contribute to advancing understanding of environmental influences on international migration more generally. Specifically, we propose an exploratory framework to take into account the role of context in shaping environmental migration across borders, including the dynamic and complex interactions between environmental and non-environmental factors at a range of scales.

    The Used Fuel Disposition Campaign (UFDC) within the Department of Energy’s Office of Nuclear Energy (DOE-NE) Fuel Cycle Technology (FCT) program has been tasked with investigating the disposal of the nation’s spent nuclear fuel (SNF) and high-level nuclear waste (HLW) for a range of potential waste forms and geologic environments. This Lessons Learned task is part of a multi-laboratory effort, with this LLNL report providing input to a Level 3 SNL milestone (System-Wide Integration and Site Selection Concepts for Future Disposition Options for HLW). The work package number is: FTLL11UF0328; the work package title is: Technical Bases / Lessons Learned; the milestone number is: M41UF032802; and the milestone title is: “LLNL Input to SNL L3 MS: System-Wide Integration and Site Selection Concepts for Future Disposition Options for HLW”. The system-wide integration effort will integrate all aspects of waste management and disposal, integrating the waste generators, interim storage, transportation, and ultimate disposal at a repository site. The review of international experience in these areas is required to support future studies that address all of these components in an integrated manner. Note that this report is a snapshot of nuclear power infrastructure and international waste management programs that is current as of August 2011, with one notable exception. No attempt has been made to discuss the currently evolving world-wide response to the tragic consequences of the earthquake and tsunami that devastated Japan on March 11, 2011, leaving more than 15,000 people dead and more than 8,000 people missing, and severely damaging the Fukushima Daiichi nuclear power complex. Continuing efforts in FY 2012 will update the data, and summarize it in an Excel spreadsheet for easy comparison and assist in the knowledge management of the study cases.

    This study aimed to describe the research on registered nurses' orientation processes in specialized hospital settings in order to illustrate directions for future research. The complex healthcare environment and the impact of nursing shortage and turnover make the hospital orientation process imperative. There is a growing recognition regarding research interests to meet the needs for evidence-based, effective and economically sound hospital orientation strategies. An integrative literature review was performed on publications from the period 2000 to 2013 included in the CINAHL and PubMed databases. English-language studies were included. Themes guiding the analysis were definition of the hospital orientation process, research topics, data collection and instruments and research evidence. Narrative synthesis was used. Eleven papers met the inclusion criteria. The conceptualization of orientation process reflected the complexity of the phenomenon. Less attention has been paid to designs to establish correlations or relationships between selected variables and hospital orientation process. The outcomes of hospital orientation programmes were limited primarily to retention and job satisfaction. The research evidence therefore cannot be evaluated as strong. The lack of an evidence-based approach makes it difficult to develop a comprehensive orientation process. Further research should explore interventions that will enhance the quality of hospital orientation practices to improve nurses' retention and job satisfaction. To provide a comprehensive hospital orientation process, hospital administrators have to put in place human resource development strategies along with practice implications and research efforts. Comprehensive hospital orientation benefits and outcomes should be visible to policy makers. © 2016 International Council of Nurses.

    Reviewed are research findings related to Japanese attitudes toward the elderly. Although several studies approaching this theme have been published in Japan since 1952, most of them are not known outside Japan because they were written in Japanese. These studies explored the presence of negative attitudes which were usually masked with rituals of respect for the elderly. People's proper use of tatemae, culturally defined normative meaning, and honne, actual feeling, in their attitudes toward the elderly is discussed as a potential source of the American idealization of aging in Japan.

    The scientific literature presents a modest amount of evidence in the use of complementary and alternative medicine (CAM). On the other hand, in practice, relevant results are common. The debates among CAM practitioners about the quality and execution of scientific research are important. Therefore, the aim of this review is to gather, synthesize and describe the differentiated methodological models that encompass the complexity of therapeutic interventions. The process of bringing evidence-based medicine into clinical practice in CAM is essential for the growth and strengthening of complementary medicines worldwide.

    Phinney, J S

    1990-11-01

    Ethnic identity is central to the psychological functioning of members of ethnic and racial minority groups, but research on the topic is fragmentary and inconclusive. This article is a review of 70 studies of ethnic identity published in refereed journals since 1972. The author discusses the ways in which ethnic identity has been defined and conceptualized, the components that have been measured, and empirical findings. The task of understanding ethnic identity is complicated because the uniqueness that distinguishes each group makes it difficult to draw general conclusions. A focus on the common elements that apply across groups could lead to a better understanding of ethnic identity.

    A review is made of irradiation experiments for water reactor safety research under way in both commercial power plants and test reactors. Such experiments are grouped in two; first, LWR fuel performance under normal and abnormal operating conditions, and second, irradiation effects on fracture toughness in LWR vessels. In the former are fuel densification, swelling, and the influence of power ramp and cycling on fuel rod, and also fuel rod behavior under accident conditions in in-reactor experiment. In the latter are the effects of neutron exposure level on the ferritic steel of pressure vessels, etc.. (auth.)

    To increase soil organic carbon content is critical for maintaining soil fertility and agricultural sustainable development and for mitigating increased greenhouse gases and the effects of global climate change. Soil aggregates are the main components of soil, and have significant effects on soil physical and chemical properties. The physical protection of soil organic carbon by soil aggregates is the important mechanism of soil carbon sequestration. This paper reviewed the organic carbon sequestration by soil aggregates, and introduced the classic and current methods in studying the mechanisms of carbon sequestration by soil aggregates. The main problems and further research trends in this study field were also discussed.

    2012-05-01

    With over 800 million active users, Facebook is changing the way hundreds of millions of people relate to one another and share information. A rapidly growing body of research has accompanied the meteoric rise of Facebook as social scientists assess the impact of Facebook on social life. In addition, researchers have recognized the utility of Facebook as a novel tool to observe behavior in a naturalistic setting, test hypotheses, and recruit participants. However, research on Facebook emanates from a wide variety of disciplines, with results being published in a broad range of journals and conference proceedings, making it difficult to keep track of various findings. And because Facebook is a relatively recent phenomenon, uncertainty still exists about the most effective ways to do Facebook research. To address these issues, the authors conducted a comprehensive literature search, identifying 412 relevant articles, which were sorted into 5 categories: descriptive analysis of users, motivations for using Facebook, identity presentation, the role of Facebook in social interactions, and privacy and information disclosure. The literature review serves as the foundation from which to assess current findings and offer recommendations to the field for future research on Facebook and online social networks more broadly. © The Author(s) 2012.

  5. Gender relations and health research: a review of current practices

    Full Text Available Abstract Introduction The importance of gender in understanding health practices and illness experiences is increasingly recognized, and key to this work is a better understanding of the application of gender relations. The influence of masculinities and femininities, and the interplay within and between them manifests within relations and interactions among couples, family members and peers to influence health behaviours and outcomes. Methods To explore how conceptualizations of gender relations have been integrated in health research a scoping review of the existing literature was conducted. The key terms gender relations, gender interactions, relations gender, partner communication, femininities and masculinities were used to search online databases. Results Through analysis of this literature we identified two main ways gender relations were integrated in health research: a as emergent findings; and b as a basis for research design. In the latter, gender relations are included in conceptual frameworks, guide data collection and are used to direct data analysis. Conclusions Current uses of gender relations are typically positioned within intimate heterosexual couples whereby single narratives (i.e., either men or women are used to explore the influence and/or impact of intimate partner gender relations on health and illness issues. Recommendations for advancing gender relations and health research are discussed. This research has the potential to reduce gender inequities in health.

    The Japan Atomic Energy Commission has exerted efforts on the research of the safety of nuclear plants in Japan, and ''Nuclear plant safety research committees'' was established in August 1974, which is composed of the government and the people. The philosophy of safety research, research and development plan, the forwarding procedure of the plan, international cooperation, for example LOFT program, and the effective feed back of the experimental results concerning nuclear safety are reviewed in this paper at first. As for the safety of nuclear reactors the basic philosophy that radio active fission products are contained in fuel or reactors with multiple barriers, (defence in depth) and almost no fission product is released outside reactor plants even at the time of hypothetical accident, is kept, and the research and development history and the future plan are described in this paper with the related technical problems. The structural safety is also explained, for example, on the philosophy ''leak before break'', pipe rupture, pipe restraint and stress analysis. The release of radioactive gas and liquid is decreased as the philosophy ''ALAP''. And probability safety evaluation method, LOCA, reactivity, accident and aseismatic design in nuclear plants in Japan are described. (Nakai, Y.)

    2012-10-01

    Systematic review of the research evidence in veterinary homeopathy has never previously been carried out. This paper presents the search methods, together with categorised lists of retrieved records, that enable us to identify the literature that is acceptable for future systematic review of randomised controlled trials (RCTs) in veterinary homeopathy. All randomised and controlled trials of homeopathic intervention (prophylaxis and/or treatment of disease, in any species except man) were appraised according to pre-specified criteria. The following databases were systematically searched from their inception up to and including March 2011: AMED; Carstens-Stiftung Homeopathic Veterinary Clinical Research (HomVetCR) database; CINAHL; Cochrane Central Register of Controlled Trials; Embase; Hom-Inform; LILACS; PubMed; Science Citation Index; Scopus. One hundred and fifty records were retrieved; 38 satisfied the acceptance criteria (substantive report of a clinical treatment or prophylaxis trial in veterinary homeopathic medicine randomised and controlled and published in a peer-reviewed journal), and were thus eligible for future planned systematic review. Approximately half of the rejected records were theses. Seven species and 27 different species-specific medical conditions were represented in the 38 papers. Similar numbers of papers reported trials of treatment and prophylaxis (n=21 and n=17 respectively) and were controlled against placebo or other than placebo (n=18, n=20 respectively). Most research focused on non-individualised homeopathy (n=35 papers) compared with individualised homeopathy (n=3). The results provide a complete and clarified view of the RCT literature in veterinary homeopathy. We will systematically review the 38 substantive peer-reviewed journal articles under the main headings: treatment trials; prophylaxis trials. Copyright © 2012 The Faculty of Homeopathy.

    2016-05-04

    Qualitative systematic reviews or qualitative evidence syntheses (QES) are increasingly recognised as a way to enhance the value of systematic reviews (SRs) of clinical trials. They can explain the mechanisms by which interventions, evaluated within trials, might achieve their effect. They can investigate differences in effects between different population groups. They can identify which outcomes are most important to patients, carers, health professionals and other stakeholders. QES can explore the impact of acceptance, feasibility, meaningfulness and implementation-related factors within a real world setting and thus contribute to the design and further refinement of future interventions. To produce valid, reliable and meaningful QES requires systematic identification of relevant qualitative evidence. Although the methodologies of QES, including methods for information retrieval, are well-documented, little empirical evidence exists to inform their conduct and reporting. This structured methodological overview examines papers on searching for qualitative research identified from the Cochrane Qualitative and Implementation Methods Group Methodology Register and from citation searches of 15 key papers. A single reviewer reviewed 1299 references. Papers reporting methodological guidance, use of innovative methodologies or empirical studies of retrieval methods were categorised under eight topical headings: overviews and methodological guidance, sampling, sources, structured questions, search procedures, search strategies and filters, supplementary strategies and standards. This structured overview presents a contemporaneous view of information retrieval for qualitative research and identifies a future research agenda. This review concludes that poor empirical evidence underpins current information practice in information retrieval of qualitative research. A trend towards improved transparency of search methods and further evaluation of key search procedures offers

    1985-02-01

    This report reviews the major activities and accomplishments of the Organic Research Section in 1984 and presents the 1985 work program. The three major areas of the Section's research work are non-metallic materials which includes applications and uses of plastics, petroleum products, coatings and elastomers; reactor waste management; and activity transport/decontamination of nuclear systems. In 1984, 50% of the Section's resources were used on studies in support of nuclear generation, 13% on reactor waste, and 37% on general activities and work in support of utilization, transmission and distribution, and thermal and hydraulic programs. About 60% of the section's work was supported by transfer and revenue funds as a result of urgent short-term work requirements which resulted in 68% of the work falling into the technical investigation, consulting and testing categories

  12. Is mindfulness research methodology improving over time? A systematic review.

    Directory of Open Access Journals (Sweden)

    Simon B Goldberg

    Full Text Available Despite an exponential growth in research on mindfulness-based interventions, the body of scientific evidence supporting these treatments has been criticized for being of poor methodological quality.The current systematic review examined the extent to which mindfulness research demonstrated increased rigor over the past 16 years regarding six methodological features that have been highlighted as areas for improvement. These feature included using active control conditions, larger sample sizes, longer follow-up assessment, treatment fidelity assessment, and reporting of instructor training and intent-to-treat (ITT analyses.We searched PubMed, PsychInfo, Scopus, and Web of Science in addition to a publically available repository of mindfulness studies.Randomized clinical trials of mindfulness-based interventions for samples with a clinical disorder or elevated symptoms of a clinical disorder listed on the American Psychological Association's list of disorders with recognized evidence-based treatment.Independent raters screened 9,067 titles and abstracts, with 303 full text reviews. Of these, 171 were included, representing 142 non-overlapping samples.Across the 142 studies published between 2000 and 2016, there was no evidence for increases in any study quality indicator, although changes were generally in the direction of improved quality. When restricting the sample to those conducted in Europe and North America (continents with the longest history of scientific research in this area, an increase in reporting of ITT analyses was found. When excluding an early, high-quality study, improvements were seen in sample size, treatment fidelity assessment, and reporting of ITT analyses.Taken together, the findings suggest modest adoption of the recommendations for methodological improvement voiced repeatedly in the literature. Possible explanations for this and implications for interpreting this body of research and conducting future studies are

    Dengue is a climate-sensitive infectious disease. Climate-based dengue early warning may be a simple, low-cost, and effective tool for enhancing surveillance and control. Scientific studies on climate and dengue in local context form the basis for advancing the development of a climate-based early warning system. This study aims to review the current status of scientific studies in climate and dengue and the prospect or challenges of such research on a climate-based dengue early warning system in a dengue-endemic country, taking Malaysia as a case study. We reviewed the relationship between climate and dengue derived from statistical modeling, laboratory tests, and field studies. We searched electronic databases including PubMed, Scopus, EBSCO (MEDLINE), Web of Science, and the World Health Organization publications, and assessed climate factors and their influence on dengue cases, mosquitoes, and virus and recent development in the field of climate and dengue. Few studies in Malaysia have emphasized the relationship between climate and dengue. Climatic factors such as temperature, rainfall, and humidity are associated with dengue; however, these relationships were not consistent. Climate change projections for Malaysia show a mounting risk for dengue in the future. Scientific studies on climate and dengue enhance dengue surveillance in the long run. It is essential for institutions in Malaysia to promote research on climate and vector-borne diseases to advance the development of climate-based early warning systems. Together, effective strategies that improve existing research capacity, maximize the use of limited resources, and promote local-international partnership are crucial for sustaining research on climate and health.

    Hicks, T.W.

    2007-01-01

    SKB is preparing licence applications for a spent nuclear fuel encapsulation plant and repository which will be supported by the SR-Site safety report. A separate safety report, SR-Can, has been produced by SKB in preparation for the SR-Site report. SKI is in the process of reviewing the SR-Can safety report. In preparation for this review, and with a view to building confidence in SKB's research activities and understanding SKB's handling of data and other information, SKI has examined SKB's application of QA measures in the management and conduct of repository research and development projects that support the SR-Can safety assessment. These preliminary investigations will serve to support the preparation of more detailed quality and technical audits of SKB's repository safety assessment after the submission of a licence application. SKI's approach to this QA review is based on the consideration of quality-affecting aspects of a selection of SKB's research and development activities. As part of this review, SKI identified the need to examine quality-related aspects of some of the many experiments and investigations that form part of SKB's repository research programme. This report presents the findings of such a review, focusing on experiments concerned with the properties and performance of the engineered barrier system. First, in order to establish a broad understanding of QA requirements for repository scientific investigations, QA procedures implemented in the management of research and development activities for the low-level radioactive waste repository near Drigg in the UK and the Waste Isolation Pilot Plant and Yucca Mountain repository projects in the US were studied. The QA procedures for experiments and tests undertaken in these projects were compared with those implemented by SKB. Key findings are: QA programmes have been implemented for each repository development programme in response to regulatory requirements. The need for regular audits of the

    Research concerning Sport Education's educational impact has shown unequivocal results according to students' personal and social development. Nevertheless, research is still sparse with respect to the model's impact on student learning outcomes. The goal of the present review is to therefore scrutinize what is currently known regarding students' learning during their participation in Sport Education. This research spans a variety of studies, cross various countries, school grades, the sports studied, as well as the methods applied and dimensions of student learning analyzed. While research on the impact of Sport Education on students' learning, as well as teachers' and students' perceptions about student learning has shown students' improvements during the participation in Sport Education seasons, there is still considerable variance in these results. For example, some studies report superior learning opportunities to boys and higher skill-level students while other studies have identified superior learning opportunities for girls and lower skill-level students. These inconsistent results can be explained by factors not considered in the Sport Education research, such as the effect of time on students' learning and the control of the teaching-learning process within Sport Education units. In this review directions for future research and practice are also described. Future research should define, implement, and evaluate protocols for student-coaches' preparation in order to understand the influence of this issue on students' learning as well as consider the implementation of hybrid approaches. Moreover, future studies should consider the interaction of gender and skill level and a retention test in the analysis of students' learning improvements in order to obtain a more realist and complete portrait of the impact of Sport Education. Finally, in order to reach an entirely understanding of the teaching-learning process, it is necessary to use research designs that

    To identify the characteristics of peer-reviewed literature on citizenship and disability published in English from 1985 to 2015. A scoping review was conducted using the Arksey and O'Malley framework. Several databases were searched for peer-reviewed journal articles including the terms citizenship and disability, impairment or handicap in their abstract or title; published between 1985 and 2015; in English. A total of 295 articles were included. Key findings are (1) the number of articles about disability and citizenship increased dramatically over the past three decades, (2) the meaning of citizenship is often left undiscussed, (3) citizenship is more often discussed in terms of access to social rights and less so in regards to contributions to society and participation in family life, technology and culture, (4) disabled people tend to be represented as a homogeneous category, (5) most studies are qualitative and non-participatory. To broaden knowledge about the situation, membership and participation of persons with disabilities in society, further research should develop the conceptual use of citizenship in relation to disability, explore different research designs, investigate various citizenship sectors and take into account the complexity of personal and social situations of persons with disabilities. Implications for Rehabilitation The notion of citizenship is closely related to the goals of rehabilitation as it touches upon issues of membership and participation in society; Understanding the multiple dimensions of citizenship will help practitioners to design and improve rehabilitation treatments and connect these not only to social citizenship rights but also to the various social roles and contributions of persons with disabilities; A better understanding of the complex relationship between citizenship and disability on the part of practitioners is crucial since strategies and policy documents about persons with disabilities often mention citizenship.

    1990-01-01

    Th research reactors operated by the Australian Nuclear Science and Technology Organization (ANSTO) comprise the 10 MW reactor HIFAR and the 100 kW reactor Moata. Although there are no power reactors in Australia the problems and issues of public concern which arise in the operation of research reactors are similar to those of power reactors although on a smaller scale. The need for independent safety surveillance has been recognized by the Australian Government and the ANSTO Act, 1987, required the Board of ANSTO to establish a Nuclear Safety Bureau (NSB) with responsibility to the Minister for monitoring and reviewing the safety of nuclear plant operated by ANSTO. The Executive Director of ANSTO operates HIFAR subject to compliance with requirements and arrangements contained in a formal Authorization from the Board of ANSTO. A Ministerial Direction to the Board of ANSTO requires the NSB to report to him, on a quarterly basis, matters relating to its functions of monitoring and reviewing the safety of ANSTO's nuclear plant. Experience has shown that the Authorization provides a suitable framework for the operational requirements and arrangements to be organised in a disciplined and effective manner, and also provides a basis for audits by the NSB by which compliance with the Board's safety requirements are monitored. Examples of the way in which the NSB undertakes its monitoring and reviewing role are given. Moata, which has a much lower operating power level and fission product inventory than HIFAR, has not been subject to a formal Authorization to date but one is under preparation

    Work plays an important role in one's life for many reasons. It provides us with economic, social, and personal satisfaction and accounts for a substantial percentage of our waking hours. But in today's knowledge-driven economy, organization of work has been changing at a warp speed as a consequence of economic, social and technological aspects of changes brought down by globalization and liberalization worldwide. While this situation has eliminated some risks of the earlier industrial era, it is introducing others. In such a dynamic business environment, where can business leaders and managers find competitive advantage? It lies in balancing people and performance goals. This is the line of approach for healthy organization research that examines organizational context with regard to: People, work organization, management practices, employee wellbeing and performance. The healthy organization concept proposes that along with the profits, employee's well being should also be an important goal for organizations. In this paper, the researcher undertakes an extensive review of literature in the mainstream business literature and establishes the agenda for healthy organization research among other research paradigms.

    2016-02-01

    Bolivia is currently undergoing a series of healthcare reforms centred around the Unified Family, Community and Intercultural Health System (SAFCI), established in 2008 and Law 475 for Provision of Comprehensive Health Services enacted in 2014 as a first step towards universal health coverage. The SAFCI model aims to establish an intercultural, intersectoral and integrated primary health care (PHC) system, but there has not been a comprehensive analysis of effective strategies towards such an end. In this systematic review, we analyse research into developing PHC in Bolivia utilizing MEDLINE, the Virtual Health Library and grey literature from Pan American Health Organization/World Health Organization's internal database. We find that although progress has been made towards implementation of a healthcare system incorporating principles of PHC, further refining the system and targeting improvements effectively will require increased research and evaluation. Particularly in the 7 years since establishment of SAFCI, there has been a dearth of PHC research that makes evaluation of such key national policies impossible. The quantity and quality of PHC research must be improved, especially quasi-experimental studies with adequate control groups. The infrastructure for such studies must be strengthened through improved financing mechanisms, expanded institutional capacity and setting national research priorities. Important for future progress are improved tracking of health indicators, which in Bolivia are often out-of-date or incomplete, and prioritization of focused national research priorities on relevant policy issues. This study aims to serve as an aid towards PHC development efforts at the national level, as well as provide lessons for countries globally attempting to build effective health systems accommodating of a multi-national population in the midst of development. © The Author 2015.

    Full Text Available Dispersal knowledge is essential for conservation management, and demand is growing. But are we accumulating dispersal knowledge at a pace that can meet the demand? To answer this question we tested for changes in dispersal data collection and use over time. Our systematic review of 655 conservation-related publications compared five topics: climate change, habitat restoration, population viability analysis, land planning (systematic conservation planning and invasive species. We analysed temporal changes in the: (i questions asked by dispersal-related research; (ii methods used to study dispersal; (iii the quality of dispersal data; (iv extent that dispersal knowledge is lacking, and; (v likely consequences of limited dispersal knowledge. Research questions have changed little over time; the same problems examined in the 1990s are still being addressed. The most common methods used to study dispersal were occupancy data, expert opinion and modelling, which often provided indirect, low quality information about dispersal. Although use of genetics for estimating dispersal has increased, new ecological and genetic methods for measuring dispersal are not yet widely adopted. Almost half of the papers identified knowledge gaps related to dispersal. Limited dispersal knowledge often made it impossible to discover ecological processes or compromised conservation outcomes. The quality of dispersal data used in climate change research has increased since the 1990s. In comparison, restoration ecology inadequately addresses large-scale process, whilst the gap between knowledge accumulation and growth in applications may be increasing in land planning. To overcome apparent stagnation in collection and use of dispersal knowledge, researchers need to: (i improve the quality of available data using new approaches; (ii understand the complementarities of different methods and; (iii define the value of different kinds of dispersal information for supporting

    Full Text Available Included in these web pages are the statements—the dismissive reviews—of some prominent education policy researchers. Most of their statements are inaccurate; it is possible that all of them are. Certainly, all of them are misleading. Each linked file includes the dismissive statements, the names of the lead authors (in bold when known and co-authors, title, source, date, and, page numbers for the statement and hyperlink to the source, when available, all listed in reverse chronological order. “Dismissive review” is the general term. In the “type” column of the files, a finer distinction is made among simply “dismissive”—meaning a claim that there is no or little previous research, “denigrating”—meaning a claim that previous research exists but is so inferior it is not worth even citing, and “firstness”—a claim to be the first in the history of the world to ever conduct such a study. For the most part, I have included statements made by “serial dismissers”, researchers who dismiss repeatedly on a variety of topics. This is done to help counter the argument that they might be innocent, actually did make an effort to look for previous research, and simply could not find it. In most cases they dismiss a research literature that is hundreds or thousands of studies deep. And, when they do that repeatedly across a variety of topics, the odds that their dismissive behavior could be innocent fade to minuscule. - See more at: http://nonpartisaneducation.org/Review/Resources/DismissiveList.htm#sthash.TXzlmZhZ.dpuf

    2005-01-01

    The programmatic, facility and criticality safety support staffs at the LLNL Plutonium Facility worked together to successfully develop and implement a project to process legacy (DNFSB Recommendation 94-1 and non-Environmental, Safety, and Health (ES and H) labeled) materials in storage. Over many years, material had accumulated in storage that lacked information to adequately characterize the material for current criticality safety controls used in the facility. Generally, the fissionable material mass information was well known, but other information such as form, impurities, internal packaging, and presence of internal moderating or reflecting materials were not well documented. In many cases, the material was excess to programmatic need, but such a determination was difficult with the little information given on MC and A labels and in the MC and A database. The material was not packaged as efficiently as possible, so it also occupied much more valuable storage space than was necessary. Although safe as stored, the inadequately characterized material posed a risk for criticality safety noncompliances if moved within the facility under current criticality safety controls. A Legacy Item Implementation Plan was developed and implemented to deal with this problem. Reasonable bounding conditions were determined for the material involved, and criticality safety evaluations were completed. Two appropriately designated glove boxes were identified and criticality safety controls were developed to safely inspect the material. Inspecting the material involved identifying containers of legacy material, followed by opening, evaluating, processing if necessary, characterizing and repackaging the material. Material from multiple containers was consolidated more efficiently thus decreasing the total number of stored items to about one half of the highest count. Current packaging requirements were implemented. Detailed characterization of the material was captured in databases

    Full Text Available Anthropogenic emissions likely pose serious threat to the stability of our environment; immediate actions are required to change the way the earth’s resources are consumed. Among the many approaches to mitigation of environmental deterioration being considered, the processes for designing, sourcing, producing and distributing products in global markets play a central role. Considerable research effort is being devoted to understanding how organisational initiatives and government policies can be structured to facilitate incorporation of sustainability into design and management of entire supply chain. In this paper, we review the current state of academic research in sustainable supply chain management, and provide a discussion of future direction and research opportunities in this field. We develop an integrative framework summarising the existing literature under four broad categories: (i strategic considerations; (ii decisions at functional interfaces; (iii regulation and government policies; and (iv integrative models and decision support tools. We aim to provide managers and industry practitioners with a nuanced understanding of issues and trade-offs involved in making decisions related to sustainable supply chain management. We conclude the paper by discussing environmental initiatives in India and the relevance of sustainability discussions in the context of the Indian economy.

    Full Text Available The applications of object-based image analysis (OBIA in remote sensing studies of wetlands have been growing over recent decades, addressing tasks from detection and delineation of wetland bodies to comprehensive analyses of within-wetland cover types and their change. Compared to pixel-based approaches, OBIA offers several important benefits to wetland analyses related to smoothing of the local noise, incorporating meaningful non-spectral features for class separation and accounting for landscape hierarchy of wetland ecosystem organization and structure. However, there has been little discussion on whether unique challenges of wetland environments can be uniformly addressed by OBIA across different types of data, spatial scales and research objectives, and to what extent technical and conceptual aspects of this framework may themselves present challenges in a complex wetland setting. This review presents a synthesis of 73 studies that applied OBIA to different types of remote sensing data, spatial scale and research objectives. It summarizes the progress and scope of OBIA uses in wetlands, key benefits of this approach, factors related to accuracy and uncertainty in its applications and the main research needs and directions to expand the OBIA capacity in the future wetland studies. Growing demands for higher-accuracy wetland characterization at both regional and local scales together with advances in very high resolution remote sensing and novel tasks in wetland restoration monitoring will likely continue active exploration of the OBIA potential in these diverse and complex environments.

    Full Text Available Innovation plays a vital role in a company’s development and in helping it keep up with new technologies and customers’ highest expectations. A large number of publications on tourism innovation reflect the interest of many authors in this topic. In the past few years several authors have approached tourism innovation, developed models of innovation in tourism, analyzed innovation types or the factors that influence innovation in this field. The purpose of this paper is to review the existing literature on tourism innovation and to identify the main research tendencies in this area of interest. Therefore, we searched for keywords like “tourism innovation”, “hospitality innovation” or “service innovation” in several databases such as Science Direct, Emerald, Sage Publications and The Center for Hospitality Research of Cornell University. Because this study focuses on tourism and hospitality innovation, there were analyzed 17 research papers regarding these aspects. Relevant findings such as factors that influence innovation in tourism and hospitality (hotels’ size, category and chain structure, introduction of ICTs, employee involvement and commitment, customer or guest requests etc., types of innovation implemented in this area and correlations between innovations’ success and hotel performance were highlighted.

    2014-03-01

    Full Text Available With the impending fossil fuel crisis, the search for and development of alternative chemical/material substitutes is pivotal in reducing mankind’s dependency on fossil resources. One of the potential substitute candidates is polyhydroxyalkanoate (PHA. PHA is a carbon-neutral and valuable polymer that could be produced from many renewable carbon sources by microorganisms, making it a sustainable and environmental-friendly material. At present, PHA is not cost competitive compared to fossil-derived products. Encouraging and intensifying research work on PHA is anticipated to enhance its economic viability in the future. The development of various biomolecular and chemical techniques for PHA analysis has led to the identification of many PHA-producing microbial strains, some of which are deposited in culture collections. Research work on PHA could be rapidly initiated with these ready-to-use techniques and microbial strains. This review aims to facilitate the start-up of PHA research by providing a summary of commercially available PHA-accumulating microbial cultures, PHA biosynthetic pathways, and methods for PHA detection, extraction and analysis.

    2016-05-01

    The concept of resilience is expected to be relevant in understanding the heterogeneous outcomes associated with schizophrenia. We reviewed recent developments in clinical studies focusing on the biological and psychological aspects of resilience in this population. We aimed to clarify current concepts of resilience in the field, elucidate gaps in the literature, and provide recommendations for future research. A total of 20 articles published between 2014 and 2015 were included. Six studies were neuroimaging studies, while the remaining studies used various psychological assessments. Most studies were cross-sectional except for three studies with naturalistic follow-up, one single-blind randomized controlled trial, and two published protocols of prospective studies. The following patterns of research were evident among the highly heterogeneous literature: studies focusing on protective factors and others emphasizing dynamic processes, studies investigating 'at-risk but resilient' groups (e.g. nonpsychotic siblings of patients with schizophrenia), and studies using psychological scales to measure resilience. The heterogeneity in how reports conceptualize, assess, and interpret resilience likely reflects the multidimensional nature of the concept itself and the lack of a 'gold standard' in assessing resilience in schizophrenia. Further research is needed to make recommendations on how to facilitate resilience in clinical care.

  12. Review of external validity reporting in childhood obesity prevention research.

    2008-03-01

    The translation and dissemination of prevention intervention evidence into practice is needed to address significant public health issues such as childhood obesity. Increased attention to and reporting of external validity information in research publications would allow for better understanding of generalizability issues relevant to successful translation. To demonstrate this potential, recent reports of childhood obesity prevention interventions were evaluated on the extent to which external validity dimensions were reported. Childhood obesity prevention studies that were controlled, long-term research trials published between 1980 and 2004 that reported a behavioral target of physical activity and/or healthy eating along with at least one anthropometric outcome were identified in 2005. Studies were summarized between 2005 and 2006 using review criteria developed by Green and Glasgow in 2006. Nineteen publications met selection criteria. In general, all studies lacked full reporting on potential generalizability and dissemination elements. Median reporting over all elements was 34.5%; the mode was 0% with a range of 0% to 100%. Most infrequent were reports of setting level selection criteria and representativeness, characteristics regarding intervention staff, implementation of intervention content, costs, and program sustainability. The evidence base for future prevention interventions can be improved by enhancing the reporting of contextual and generalizability elements central to translational research. Such efforts face practical hurdles but could provide additional explanation for variability in intervention outcomes, insights into successful adaptations of interventions, and help guide policy decisions.

    Full Text Available Dependence on information, including for some of the world’s largest organisations such as governments and multi-national corporations, has grown rapidly in recent years. However, reports of information security breaches and their associated consequences indicate that attacks are escalating on organisations conducting these information-based activities. Organisations need to formulate strategy to secure their information, however gaps exist in knowledge. Through a thematic review of academic security literature, (1 we analyse the antecedent conditions that motivate the adoption of a comprehensive information security strategy, (2 the conceptual elements of strategy and (3 the benefits that are enjoyed post-adoption. Our contributions include a definition of information security strategy that moves from an internally-focussed protection of information towards a strategic view that considers the organisation, its resources and capabilities, and its external environment. Our findings are then used to suggest future research directions.

    2018-02-01

    Full Text Available Knowledge about the function and functioning of single or multiple interacting genes is of the utmost significance for understanding the organism as a whole and for accurate livestock improvement through genomic selection. This includes, but is not limited to, understanding the ontogenetic and environmentally driven regulation of gene action contributing to simple and complex traits. Genetically modified mice, in which the functions of single genes are annotated; mice with reduced genetic complexity; and simplified structured populations are tools to gain fundamental knowledge of inheritance patterns and whole system genetics and genomics. In this review, we briefly describe existing mouse resources and discuss their value for fundamental and applied research in livestock.

    A microgrid is particularly a portion of the power distribution system that comprises distributed generation, energy storage and loads. To be capable of operating in parallel to the grid, as an autonomous power island and in transition modes, microgrids must be robust in controlling the local voltage and frequency, and protecting the network and equipment connected to the microgrid. It also needs to facilitate demand side management and resynchronization. This paper presents a review of existing microgrid test networks around the world (North America, Europe and Asia) and some significantly different microgrid simulation networks present in the literature. Paper is focused on the test systems and available microgrid control options. A summary table comparing and contrasting the existing test systems is presented. The paper is concluded highlighting the worthy findings and possible areas of research that would enhance practical use of microgrid facilities. (author)

  19. Cluster protocols in Underwater Sensor Networks: a Research Review

    Directory of Open Access Journals (Sweden)

    K. Ovaliadis

    2014-07-01

    Full Text Available Underwater Wireless Sensor Networks (UWSN have different characteristics in relation to terrestrial wireless sensor networks; such as limited bandwidth capacity, high propagation delays and limited battery power. Although there has been much work completed in developing protocols and models for terrestrial networks, these are rarely applicable for underwater sensor networks. Up to today major efforts have been made for designing efficient protocols while considering the underwater communication characteristics. An important issue on this research area is the construction of an efficient clustering algorithm. Clustering in the context of UWSN is important as it contributes a great deal towards the efficient use of energy resources. This paper reviews the most significant cluster based protocols proposed for UWSN. Major performance issues of these protocols with respect to the network conditions such as packet delivery ratio, average packet delay, node mobility effect and energy consumption are examined. The advantages and disadvantages of each protocol are also pointed out.

    2003-01-01

    The use of downsizing as management's strategic response to environmental and institutional changes is prevalent in all U.S. industries, including healthcare. The popular and research literature is inundated with reports on companies undergoing various stages of restructuring, which often include one or more staff reductions. This article provides a review of downsizing literature published from 1985 to 2002. Although the findings and conclusions of these articles are generally inconsistent, the prevailing opinion is that for downsizing to be successful, effective planning must occur long before, during, and after downsizing. Additionally, a downsizing plan should be included in the strategic management plan of all organizations, regardless of whether they plan to downsize or not. By including such a plan, the organization will be better prepared to begin the staff-reduction process should it be forced to do so in response to environmental changes. Finally, providing ample support and protection for staff is key to the organization's recovery and growth. The lessons provided in this literature review should assist healthcare managers in deciding how to plan and structure potential staff reductions.

    An 8 March congressional hearing about the U.S. National Science Foundation's Major Research Equipment and Facilities Construction (NSF MREFC) account focused on fiscal management and accountability of projects in that account and reviewed concerns raised by NSF's Office of Inspector General (OIG). NSF established the MREFC account in 1995 to better plan and manage investments in major equipment and facilities projects, which can cost from tens of millions to hundreds of millions of dollars, and the foundation has funded 17 MREFC projects since then. The Obama administration's proposed fiscal year (FY) 2013 budget includes funding for four MREFC projects: Advanced Laser Gravitational-Wave Observatory (AdvLIGO), Advanced Technology Solar Telescope (ATST), National Ecological Observatory (NEON), and Ocean Observatories Initiative (OOI). The hearing, held by a subcommittee of the House of Representatives' Committee on Science, Space, and Technology, reviewed management oversight throughout the life cycles of MREFC projects and concerns raised in recent OIG reports about the use of budget contingency funds. NSF's February 2012 manual called "Risk management guide for large facilities" states that cost contingency is "that portion of the project budget required to cover `known unknowns,'" such as planning and estimating errors and omissions, minor labor or material price fluctuations, and design developments and changes within the project scope. Committee members acknowledged measures that NSF has made to improve the MREFC oversight process, but they also urged the agency to continue to take steps to ensure better project management.

    Full Text Available The purpose of this mixed research integrative review is to determine factors that influence relocation transitions for older adults who are considering a move from independent living to supervised housing, such as assisted living, using the Theory of Planned Behavior as a conceptual guide. PubMED, CINAHL, and PsychInfo databases were queried using key words: relocation, transition, older adults, and, elderly and time limited from 1992 to 2014. Sixteen articles were retained for review. The majority of articles, qualitative in design, reveal that older adults who comprehend the need to move and participate in the decision-making process of a relocation adjust to new living environments with fewer negative outcomes than older adults who experience a forced relocation. The few quantitative articles examined the elements of impending relocation using a variety of instruments but support the necessity for older adults to recognize the possibility of a future move and contribute to the relocation process. Additionally, the influence of family, friends, and health care providers provides the older adult with support and guidance throughout the process.

    Full Text Available To review the existing literature on depression among elderly arising from India. Search was carried out using PubMed, Google Scholar, Google, and Medknow search engines to identify the relevant studies. Most of the literatures that are available are in terms of prevalence of depression. Community-based studies involving 70 to 7,150 elderly subjects report prevalence rate varying from 8.9% to 62.16%. Clinic-based studies involving 50 to 5,260 participants report prevalence rates ranging from 42.4% to 72%. Studies have reported depression to be more common among females. Other demographic factors that have been associated with depression among elderly include being unmarried, divorced or widowed elderly, residing in rural locality, being illiterate, increasing age, lower socioeconomic status, and unemployment. Depression has also been shown to be associated with various psychosocial factors, lifestyle and dietary factors, and presence of chronic physical illness. There are limited data on various therapeutic interventions. Available data suggest usefulness of pranayam, cognitive behavior therapy, and electroconvulsive therapy. The review of data suggests that prevalence of depression among elderly in India is high. However, there is lack of data on symptom profile and limited data is available on various therapeutic interventions for the management of depression in elderly from India. There is urgent need to conduct large multicentric studies to fill this void in research.

    Full Text Available This is an integrative review that aimed to synthesize the scientific knowledge published in national nursing journals about the prevention of cervical cancer. It was made a literature review in May 2009 in BIREME, covering the national nursing publications, from 1999 to 2009. We identified 15 articles that comprised the study sample. Of these, 11 addressed the nursing care, 6 were about prevention of cancer and 5 were about risk factors for such disease. In 4 articles the studies were accomplished in the Family Health Care Unit (UBASF which was the most prevalent place. It was found out that 6 of the articles used the qualitative method. The most studied population was formed by users of the Family Health Care Unit, in 3 studies. It was so concluded that the national research about this topic was related to the problems identified in health places, either in the effectiveness of the examination, in the knowledge of users or in conducted health education.

    The ability to reproduce experiments is a defining principle of science. Reproducibility of clinical research has received relatively little scientific attention. However, it is important as it may inform clinical practice, research agendas, and the design of future studies. We used scoping review methods to examine reproducibility within a cohort of randomized trials examining clinical critical care research and published in the top general medical and critical care journals. To identify relevant clinical practices, we searched the New England Journal of Medicine, The Lancet, and JAMA for randomized trials published up to April 2016. To identify a comprehensive set of studies for these practices, included articles informed secondary searches within other high-impact medical and specialty journals. We included late-phase randomized controlled trials examining therapeutic clinical practices in adults admitted to general medical-surgical or specialty intensive care units (ICUs). Included articles were classified using a reproducibility framework. An original study was the first to evaluate a clinical practice. A reproduction attempt re-evaluated that practice in a new set of participants. Overall, 158 practices were examined in 275 included articles. A reproduction attempt was identified for 66 practices (42%, 95% CI 33-50%). Original studies reported larger effects than reproduction attempts (primary endpoint, risk difference 16.0%, 95% CI 11.6-20.5% vs. 8.4%, 95% CI 6.0-10.8%, P = 0.003). More than half of clinical practices with a reproduction attempt demonstrated effects that were inconsistent with the original study (56%, 95% CI 42-68%), among which a large number were reported to be efficacious in the original study and to lack efficacy in the reproduction attempt (34%, 95% CI 19-52%). Two practices reported to be efficacious in the original study were found to be harmful in the reproduction attempt. A minority of critical care practices with research published

    [1] We develop a global-scale P wave velocity model (LLNL-G3Dv3) designed to accurately predict seismic travel times at regional and teleseismic distances simultaneously. The model provides a new image of Earth's interior, but the underlying practical purpose of the model is to provide enhanced seismic event location capabilities. The LLNL-G3Dv3 model is based on ∼2.8 millionP and Pnarrivals that are re-processed using our global multiple-event locator called Bayesloc. We construct LLNL-G3Dv3 within a spherical tessellation based framework, allowing for explicit representation of undulating and discontinuous layers including the crust and transition zone layers. Using a multiscale inversion technique, regional trends as well as fine details are captured where the data allow. LLNL-G3Dv3 exhibits large-scale structures including cratons and superplumes as well numerous complex details in the upper mantle including within the transition zone. Particularly, the model reveals new details of a vast network of subducted slabs trapped within the transition beneath much of Eurasia, including beneath the Tibetan Plateau. We demonstrate the impact of Bayesloc multiple-event location on the resulting tomographic images through comparison with images produced without the benefit of multiple-event constraints (single-event locations). We find that the multiple-event locations allow for better reconciliation of the large set of direct P phases recorded at 0–97° distance and yield a smoother and more continuous image relative to the single-event locations. Travel times predicted from a 3-D model are also found to be strongly influenced by the initial locations of the input data, even when an iterative inversion/relocation technique is employed.

    2017-08-08

    Systematic identification of evidence in health policy can be time-consuming and challenging. This study examines three questions pertaining to systematic reviews on obesity prevention policy, in order to identify the most efficient search methods: (1) What percentage of the primary studies selected for inclusion in the reviews originated in scholarly as opposed to gray literature? (2) How much of the primary scholarly literature in this topic area is indexed in PubMed/MEDLINE? (3) Which databases index the greatest number of primary studies not indexed in PubMed, and are these databases searched consistently across systematic reviews? We identified systematic reviews on obesity prevention policy and explored their search methods and citations. We determined the percentage of scholarly vs. gray literature cited, the most frequently cited journals, and whether each primary study was indexed in PubMed. We searched 21 databases for all primary study articles not indexed in PubMed to determine which database(s) indexed the highest number of these relevant articles. In total, 21 systematic reviews were identified. Ten of the 21 systematic reviews reported searching gray literature, and 12 reviews ultimately included gray literature in their analyses. Scholarly articles accounted for 577 of the 649 total primary study papers. Of these, 495 (76%) were indexed in PubMed. Google Scholar retrieved the highest number of the remaining 82 non-PubMed scholarly articles, followed by Scopus and EconLit. The Journal of the American Dietetic Association was the most-cited journal. Researchers can maximize search efficiency by searching a small yet targeted selection of both scholarly and gray literature resources. A highly sensitive search of PubMed and those databases that index the greatest number of relevant articles not indexed in PubMed, namely multidisciplinary and economics databases, could save considerable time and effort. When combined with a gray literature search and

  8. Estimating The Reliability of the Lawrence Livermore National Laboratory (LLNL) Flash X-ray (FXR) Machine

    At Lawrence Livermore National Laboratory (LLNL), our flash X-ray accelerator (FXR) is used on multi-million dollar hydrodynamic experiments. Because of the importance of the radiographs, FXR must be ultra-reliable. Flash linear accelerators that can generate a 3 kA beam at 18 MeV are very complex. They have thousands, if not millions, of critical components that could prevent the machine from performing correctly. For the last five years, we have quantified and are tracking component failures. From this data, we have determined that the reliability of the high-voltage gas-switches that initiate the pulses, which drive the accelerator cells, dominates the statistics. The failure mode is a single-switch pre-fire that reduces the energy of the beam and degrades the X-ray spot-size. The unfortunate result is a lower resolution radiograph. FXR is a production machine that allows only a modest number of pulses for testing. Therefore, reliability switch testing that requires thousands of shots is performed on our test stand. Study of representative switches has produced pre-fire statistical information and probability distribution curves. This information is applied to FXR to develop test procedures and determine individual switch reliability using a minimal number of accelerator pulses

    We have continued our laboratory studies of forward gasification in small blocks of coal mounted in 55-gal drums. A steam/oxygen mixture is fed into a small hole drilled longitudinally through the center of the block, the coal is ignited near the inlet and burns toward the outlet, and the product gases come off at the outlet. Various diagnostic measurements are made during the course of the burn, and afterward the coal block is split open so that the cavity can be examined. Development work continues on our mathematical model for the small coal block experiments. Preparations for the large block experiments at a coal outcrop in the Tono Basin of Washington State have required steadily increasing effort with the approach of the scheduled starting time for the experiments (Fall 1981). Also in preparation is the deep gasification experiment, Tono 1, planned for another site in the Tono Basin after the large block experiments have been completed. Wrap-up work continues on our previous gasification experiments in Wyoming. Results of the postburn core-drilling program Hoe Creek 3 are presented here. Since 1976 the Soviets have been granted four US patents on various aspects of the underground coal gasification process. These patents are described here, and techniques of special interest are noted. Finally, we include ten abstracts of pertinent LLNL reports and papers completed during the quarter.

    The Microwave Source Facility at the Lawrence Livermore National Laboratory (LLNL) is studying the application of induction accelerator technology to high-power microwave generators suitable for linear collider power sources. The authors report on the results of two experiments, both using the Choppertron's 11.4 GHz modulator and a 5-MeV, 1-kA induction beam. The first experimental configuration has a single traveling wave output structure designed to produce in excess of 300 MW in a single fundamental waveguide. This output structure consists of 12 individual cells, the first two incorporating de-Q-ing circuits to dampen higher order resonant modes. The second experiment studies the feasibility of enhancing beam to microwave power conversion by accelerating a modulated beam with induction cells. Referred to as the ''Reacceleration Experiment,'' this experiment consists of three traveling-wave output structures designed to produce about 125 MW per output and two induction cells located between the outputs. Status of current and planned experiments are presented

    The use of ultra fast laser pulses to generate very high brightness, ultra short (fs to ps) pulses of x-rays is a topic of great interest to the x-ray user community. In principle, femto-second-scale pump-probe experiments can be used to temporally resolve structural dynamics of materials on the time scale of atomic motion. The development of sub-ps x-ray pulses will make possible a wide range of materials and plasma physics studies with unprecedented time resolution. A current project at LLNL will provide such a novel x-ray source based on Thomson scattering of high power, short laser pulses with a high peak brightness, relativistic electron bunch. The system is based on a 5 mm-mrad normalized emittance photo-injector, a 100 MeV electron RF linac, and a 300 mJ, 35 fs solid-state laser system. The Thomson x-ray source produces ultra fast pulses with x-ray energies capable of probing into high-Z metals, and a high flux per pulse enabling single shot experiments. The system will also operate at a high repetition rate (∼ 10 Hz). (authors)

    In September 1982 the Hazards Control Department of the Lawrence Livermore National Laboratory (LLNL) began a final radiological survey of a former low-level radioactive waste storage area called the Taxi Strip so that the area could be released for construction of an office building. Collection of soil samples at the location of a proposed sewer line led to the discovery of an old disposal pit containing soil contaminated with low-level radioactive waste and organic solvents. The Taxi Strip area was excavated leading to the discovery of three additional small pits. The clean-up of Pit No. 1 is considered to be complete for radioactive contamination. The results from the chlorinated solvent analysis of the borehole samples and the limited number of samples analyzed by gas chromatography/mass spectrometry indicate that solvent clean-up at this pit is complete. This is being verified by gas chromatography/mass spectrometry analysis of a few additional soil samples from the bottom sides and ends of the pit. As a precaution, samples are also being analyzed for metals to determine if further excavation is necessary. Clean-up of Pits No. 2 and No. 3 is considered to be complete for radioactive and solvent contamination. Results of analysis for metals will determine if excavation is complete. Excavation of Pit No. 4 which resulted from surface leakage of radioactive contamination from an evaporation tray is complete

    Under the US Department of Energy's (DOE's) Office of Technology Development (OTD)-Robotic Technology Development Program (RTDP), the Waste Processing Operations (WPO) Program was initiated in FY92 to address the development of automated material handling and automated chemical and physical processing systems for mixed wastes. The Program's mission was to develop a strategy for the treatment of all DOE mixed, low-level, and transuranic wastes. As part of this mission, DOE's Mixed Waste Integrated Program (MWIP) was charged with the development of innovative waste treatment technologies to surmount shortcomings of existing baseline systems. Current technology advancements and applications results from cooperation of private industry, educational institutions, and several national laboratories operated for DOE. This summary document presents the LLNL Environmental Restoration and Waste Management (ER and WM) Automation and Robotics Section's contributions in support of DOE's FY93 WPO Program. This document further describes the technological developments that were integrated in the 1993 Mixed Waste Operations (MWO) Demonstration held at SRTC in November 1993

    The EBIT Calorimeter Spectrometer (ECS) is currently being completed and will be installed at the EBIT facility at the Lawrence Livermore National Laboratory in October 2007. The ECS will replace the smaller XRS/EBIT microcalorimeter spectrometer that has been in almost continuous operation since 2000. The XRS/EBIT was based on a spare laboratory cryostat and an engineering model detector system from the Suzaku/XRS observatory program. The new ECS spectrometer was built to be a low maintenance, high performance implanted silicon microcalorimeter spectrometer with 4 eV resolution at 6 keV, 32 detector channels, 10 (micro)s event timing, and capable of uninterrupted acquisition sessions of over 60 hours at 50 mK. The XRS/EBIT program has been very successful, producing many results on topics such as laboratory astrophysics, atomic physics, nuclear physics, and calibration of the spectrometers for the National Ignition Facility. The ECS spectrometer will continue this work into the future with improved spectral resolution, integration times, and ease-of-use. We designed the ECS instrument with TES detectors in mind by using the same highly successful magnetic shielding as our laboratory TES cryostats. This design will lead to a future TES instrument at the LLNL EBIT. Here we discuss the legacy of the XRS/EBIT program, the performance of the new ECS spectrometer, and plans for a future TES instrument.

An emergent field of research on the topic refers to what has been described as social jetlag, the biological misalignment that arises from alternated work and free days. However, to the present moment, there is still controversial evidence on the effects of such a phenomenon to human health.Objective: The aim of this study was to identify current peer-reviewed evidence of the health and behavioral risks associated with social jetlag.Method: We conducted a systematic review of the literature on PubMed, Scopus, Embase and LILACS electronic databases using the terms “social AND (jet lag OR jetlag”. The search was finalized on August 22, 2016, resulting in 26 research articles included in the review.Results and discussion: Our results point to a variety of health and behavioral outcomes that seem to be associated with the mismatch existent between work or study days and free days. They are epilepsy, minor psychiatric symptoms, aggression and conduct problems, mood disorders, cognitive impairment (eg, work and academic performance, substance use, cardiometabolic risk and adverse endocrine profiles

    A database of research publication was constructed for the purpose of grasping all of the research activities at the Research Reactor Institute, Kyoto University. The database named KURRIP collects all of the research publications of the Institute by not only its own staff but also visiting scientists. The publications are in the form of original papers, review papers, papers in proceedings, short notes and letters, synopses over 3 pages presented orally at scientific meeting, books and doctoral theses. At present, the KURRIP database contains the information on 6,210 items which have been published for 30 years since the Institute was established as an interuniversity research institute for joint use of a research reactor and other related large facilities in 1963. By utilizing the KURRIP database, the analyses have been done: (1) affiliation of the authors, (2) kind of publications, (3) classification of publishers, (4) research fields, and (5) experimental facilities. The KURRIP database is now stored in the Data Processing Center of Kyoto University and can be utilized through a computer center at one of the main national universities in Japan. (author)

    Over the past 20 years, sonar imaging technology particularly for the high-technology sector has been a focus of research, in which many developed countries, especially those with coast lines, have been competing with each other. It has seen a rapid development with increasing widespread applications that has played an important and irreplaceable role in underwater exploration with great prospects for social, economic, scientific, and military benefits. The fundamental techniques underlying sonar imaging, including multi-beamforming, synthetic-aperture and inverse synthetic-aperture sonar, acoustic lensing, and acoustical holography, are described in this paper. This is followed by a comprehensive and systematic review on the advantages and disadvantages of these imaging techniques, applicability conditions, development trends, new ideas, new methods, and improvements in old methods over recent years with an emphasis on the situation in China, along with a bold and constructive prediction to some development characteristics of sonar imaging technology in the near future in China. The perspectives presented in this paper are offered with the idea of providing some degree of guidance and promotion of research on sonar imaging technology.

    To explore the ability of an integrated health information infrastructure to support outcomes research. A systematic review of articles published from 1983 to 2012 by Regenstrief Institute investigators using data from an integrated electronic health record infrastructure involving multiple provider organisations was performed. Articles were independently assessed and classified by study design, disease and other metadata including bibliometrics. A total of 190 articles were identified. Diseases included cognitive, (16) cardiovascular, (16) infectious, (15) chronic illness (14) and cancer (12). Publications grew steadily (26 in the first decade vs. 100 in the last) as did the number of investigators (from 15 in 1983 to 62 in 2012). The proportion of articles involving non-Regenstrief authors also expanded from 54% in the first decade to 72% in the last decade. During this period, the infrastructure grew from a single health system into a health information exchange network covering more than 6 million patients. Analysis of journal and article metrics reveals high impact for clinical trials and comparative effectiveness research studies that utilised data available in the integrated infrastructure. Integrated information infrastructures support growth in high quality observational studies and diverse collaboration consistent with the goals for the learning health system. More recent publications demonstrate growing external collaborations facilitated by greater access to the infrastructure and improved opportunities to study broader disease and health outcomes. Integrated information infrastructures can stimulate learning from electronic data captured during routine clinical care but require time and collaboration to reach full potential. © 2015 Health Libraries Group.
