    1992-01-01

    I summarize recent work at Cornell on B Factory simulations. My talk includes a brief review of the Cornell proposal, some estimates we have developed for measuring sinγ and a progress report on the use of kinematic fitting. Because of the recent accumulation of data at CLEO II, the author devote a substantial part of my summary to recent B physics results, especially those connected with CP violation

    2017-01-01

    Cornell Alliance for Science has launched an initiative in which "citizen scientists" are called upon to evaluate studies on health risks of genetically modified (GM) crops and foods. The purpose is to establish whether the consensus on GM food safety claimed by the American Association for the Advancement of Science (AAAS) is supported by a review of the scientific literature. The Alliance's citizen scientists are examining more than 12,000 publication abstracts to quantify how far the scientific literature supports the AAAS's statement. We identify a number of fundamental weaknesses in the Alliance's study design, including evaluation is based only on information provided in the publication abstract; there is a lack of clarity as to what material is included in the 12,000 study abstracts to be reviewed, since the number of appropriately designed investigations addressing GM food safety are few; there is uncertainty as to whether studies of toxic effects arising from GM crop-associated pesticides will be included; there is a lack of clarity regarding whether divergent yet equally valid interpretations of the same study will be taken into account; and there is no definition of the cutoff point for consensus or non-consensus on GM food safety. In addition, vital industry proprietary biosafety data on GM crops and associated pesticides are not publicly available and is thus cannot inform this project. Based on these weaknesses in the study design, we believe it is questionable as to whether any objective or meaningful conclusion can be drawn from the Alliance's initiative.

  6. Cornell and Marseille

    International Nuclear Information System (INIS)

    Anon.

    1993-01-01

    A major theme running through the Cornell meeting, as with most physics meetings these days, was the need to look hard at suppressed or forbidden reactions for signs of an excess or positive signal, suggesting that at last something new might be happening. At Cornell, Jack Ritchie (Texas) covered the kaon front, while Anthony Sanda (Nagoya) gave an overall status report. Rare processes mediated by second order effects (two quarks mechanisms coupled back-to-back) have been seen by the CLEO detector at Cornell (June page 1), and Sanda suggested that other such effects could now begin to show up. Last year's major international meeting at Dallas marked the debut of physics results from the Zeus and H1 experiments at the new and unique HERA electron-proton collider at DESY, Hamburg. This year HERA's collision rate is climbing, and the entire 1992 collision score was matched in just one weekend at the end of July. Cornell's plenary-only programme featured back-to-back presentations from H1 (John Dainton, Liverpool) and Zeus (John Martin, Toronto). Both experiments are beginning to see signs of the tight particle clusters ('jets') indicative of constituent quark/ gluon interactions deep inside the 'target' protons. HERA probes the structure of the proton in an unexplored kinematical region (quark momentum fraction x approaching 10 -4 ), and H1 was the first to see how this structure develops as x decreases. As the proton is probed in increasingly finer detail, it shows a richer quark content as more transient ('virtual') quark/gluon contributions come into play. This structure evolution provides important information for quark field theory, with additional mechanisms opening up

    1982-01-01

    The electron-positron storage ring CESR, at Cornell is now operating regularly with a luminosity of over 10 31 per cm 2 per s (400 inverse nanobarns) and, thanks to the money saved by operating the magnet of the CLEO detector with a superconducting coil, the number of hours available for physics is not restricted. The research remains concentrated around the upsilon resonances (operating the storage ring at just over 5 GeV per beam). (orig./HSI).

  9. CORNELL: Synchrotron 25

    International Nuclear Information System (INIS)

    Anon.

    1993-01-01

    A recent celebration marked the twenty-fifth anniversary of the Cornell Electron Synchrotron. The major milestone in the commissioning of the synchrotron was on October 11, 1967 when Helen Edwards, Boyce McDaniel, and Maury Tigner achieved a 7 GeV beam, a worldrecord energy for electron synchrotrons at that time. Like so many advances in experimental physics, this occurred early in the morning - 3 a.m.! The transition from accelerator commissioning to high energy physics operation was extremely rapid; 7 GeV operation for data collection was routine just five weeks later. Throughout its life as a source of photon and electron beams for fixed target experiments, the synchrotron maintained energy leadership for circular electron machines. Originally designed for operation at 10 GeV, eventually it consistently provided beams for experiments at energies up to 11.6 GeV. It now operates at 5 GeV, serving as the injector for the CESR electron-positron storage ring. Robert Wilson was director of the laboratory during the design and most of the construction of the machine. He left near the end of the construction to become the first director of Fermilab and was replaced by Boyce McDaniel, who guided the laboratory from the completion of the synchrotron to the construction and early operation of CESR. Wilson recalled how the laboratory had originally proposed a 3 GeV turnkey machine to be built entirely by industry and would fit in the space previously occupied by earlier Cornell accelerators. However, members of the laboratory realized that 3 GeV would not open new physics frontiers, that the construction of the accelerator was much of the fun of doing high energy physics experiments, and that a more challenging project was needed. This led to the proposal for the 10 GeV synchrotron which was built in the ''Cornell Style'' with many of the components fabricated and nearly all of the assembly done at Cornell

    the strongest “paradigms” in the field is a tradition derived from the Cranfield experiments in the 1960s and the bibliometric research following the publication of Science Citation Index from 1963 and forward. Among the competing theoretical frameworks, ‘the cognitive view’ became influential from the 1970s......This paper presents a brief history of information science (IS) as viewed by the author. The term ‘information science’ goes back to 1955 and evolved in the aftermath of Claude Shannon’s ‘information theory’ (1948), which also inspired research into problems in fields of library science...... and documentation. These subjects were a main focus of what became established as ‘information science’, which from 1964 onwards was often termed ‘library and information science’ (LIS). However, the usefulness of Shannon’s information theory as the theoretical foundation of the field was been challenged. Among...

    Full Text Available Background: The United States Medical Licensing Examination (USMLE is increasing clinical content on the Step 1 exam; thus, inclusion of clinical applications within the basic science curriculum is crucial. Including simulation activities during basic science years bridges the knowledge gap between basic science content and clinical application. Purpose: To evaluate the effects of a one-off, 1-hour cardiovascular simulation intervention on a summative assessment after adjusting for relevant demographic and academic predictors. Methods: This study was a non-randomized study using historical controls to evaluate curricular change. The control group received lecture (n l=515 and the intervention group received lecture plus a simulation exercise (nl+s=1,066. Assessment included summative exam questions (n=4 that were scored as pass/fail (≥75%. USMLE-style assessment questions were identical for both cohorts. Descriptive statistics for variables are presented and odds of passage calculated using logistic regression. Results: Undergraduate grade point ratio, MCAT-BS, MCAT-PS, age, attendance at an academic review program, and gender were significant predictors of summative exam passage. Students receiving the intervention were significantly more likely to pass the summative exam than students receiving lecture only (P=0.0003. Discussion: Simulation plus lecture increases short-term understanding as tested by a written exam. A longitudinal study is needed to assess the effect of a brief simulation intervention on long-term retention of clinical concepts in a basic science curriculum.

  20. CHESS-the Cornell High Energy Synchrotron Source

    Batterman, B.W.; Cornell Univ., Ithaca, NY

    1980-01-01

    The Wilson Laboratory at Cornell University has done pioneering work on development of high energy synchrotrons. In the last decade, the 12 GeV synchrotron has been the most energetic electron synchrotron in the world. In 1975 plans were formulated to build a 4-8 GeV storage ring in the same tunnel as the synchrotron and to use the latter as the injector for the storage ring. This small radius (the normal bend magnets have R = 87 m), coupled with the relatively high electron energy of the storage ring, makes these magnets potent sources of synchrotron radiation. In June of 1978 the National Science Foundation funded a project to create CHESS, the Cornell High Energy Synchrotron Source. (orig./FKS)

    Khan, H.A.; Qureshi, I.E.

    1999-01-01

    The technique of Solid State Nuclear Track Detection (SSNTD) has matured since long as a viable method of charged particle detection. The usage of this method has been successfully extended to neutron detection and gamma dose measurements as well. The etch-track mechanism has been further exploited to generate a major application area of nuclear track filters. In spite of the remarkable diversity of SSNTD applications that have emerged over the years in different fields, its potential is by no means saturated. In this article, a brief review of SSNTD applications is presented with reference to contemporary interests in science and technology. For convenience, the coverage of topics is organized under broad categories of Nuclear Physics, Materials Research, Geology, Environmental Science and allied technologies. While identifying high interest areas, those with limited but innovative applications are also mentioned. In some cases, the important results are quoted for the purpose of illustrating the strength of track detection method. In general, the presentation is aimed at providing a broad perspective of current SSNTD uses instead of detailed description of individual applications. The coverage is selective rather than exhaustive and portrays authors' preferences. Some comments related to the adoption of this technique as a mainstream method of detection are also given

    NASA's Universe of Learning creates and delivers science-driven, audience-driven resources and experiences designed to engage and immerse learners of all ages and backgrounds in exploring the universe for themselves. The project is a unique partnership between the Space Telescope Science Institute, Caltech/IPAC, Jet Propulsion Laboratory, Smithsonian Astrophysical Observatory, and Sonoma State University and is part of the NASA SMD Science Activation Collective. The NASA’s Universe of Learning projects pull on the expertise of subject matter experts (scientist and engineers) from across the broad range of NASA Astrophysics themes and missions. One such project, which draws strongly on the expertise of the community, is the NASA’s Universe of Learning Science Briefings, which is done in collaboration with the NASA Museum Alliance. This collaboration presents a monthly hour-long discussion on relevant NASA astrophysics topics or events to an audience composed largely of informal educators from informal learning environments. These professional learning opportunities use experts and resources within the astronomical community to support increased interest and engagement of the informal learning community in NASA Astrophysics-related concepts and events. Briefings are designed to create a foundation for this audience using (1) broad science themes, (2) special events, or (3) breaking science news. The NASA’s Universe of Learning team engages subject matter experts to be speakers and present their science at these briefings to provide a direct connection to NASA Astrophysics science and provide the audience an opportunity to interact directly with scientists and engineers involved in NASA missions. To maximize the usefulness of the Museum Alliance Science Briefings, each briefing highlights resources related to the science theme to support informal educators in incorporating science content into their venues and/or interactions with the public.

    Full Text Available We show a lot of respect for science today. To back up our claims, we tend to appeal to scientific methods. It seems that we all agree that these methods are effective for gaining the truth. We can ask why science has its special status as a supplier of knowledge about our external world and our bodies. Of course, one should not always trust what scientists say. Nonetheless, epistemological justification of scientific claims is really a big project for philosophers of science. Philosophers of science are interested in knowing how science proves what it does claim and why it gives us good reasons to take these claims seriously. These questions are epistemological questions. Epistemology is a branch of philosophy which deals with knowledge claims and justification. Besides epistemological questions, metaphysical and ethical issues in science are worthy of philosophical scrutiny. This paper gives a short survey of these intellectually demanding issues.

    Science.gov (United States)

    Schweiss, Robert J.; Ho, Evelyn; Ullman, Richard; Samadi, Shahin

    2006-01-01

    The NPOESS Preparatory Project (NPP) provides remotely-sensed land, ocean, atmospheric, ozone, and sounder data that will serve the meteorological and global climate change scientific communities while also providing risk reduction for the National Polar-orbiting Operational Environmental Satellite System (NPOESS), the U.S. Government s future low-Earth orbiting satellite system monitoring global weather and environmental conditions. NPOESS and NPP are a new era, not only because the sensors will provide unprecedented quality and volume of data but also because it is a joint mission of three federal agencies, NASA, NOAA, and DoD. NASA's primary science role in NPP is to independently assess the quality of the NPP science and environmental data records. Such assessment is critical for making NPOESS products the best that they can be for operational use and ultimately for climate studies. The Science Data Segment (SDS) supports science assessment by assuring the timely provision of NPP data to NASA s science teams organized by climate measurement themes. The SDS breaks down into nine major elements, an input element that receives data from the operational agencies and acts as a buffer, a calibration analysis element, five elements devoted to measurement based quality assessment, an element used to test algorithmic improvements, and an element that provides overall science direction. This paper will describe how the NPP SDS will leverage on NASA experience to provide a mission-reliable research capability for science assessment of NPP derived measurements.

    2017-04-01

    Contributions from men to radiation science are well known, particularly the early contributions from such luminaries as William Roentgen, James Chadwick, Niels Bohr, Robert Oppenheimer, and the like. Although not ignored per se, beyond Marie Curie and Lise Meitner, the contributions of female nuclear scientists are not as widely recognized. This paper provides a concise historical summary of contributions to radiation science from the discovery of radiation through the current status of international leadership within the radiation protection community. Beyond lead scientists and academics, this paper also considers support personnel as well as the role women have played in the advancement of radiation epidemiology.

    2017-10-01

    This paper reviews several literatures concerning the theories and model that could be applied for science motivation for upper secondary school learners (16-17 years old) in order to make the learning experience more amazing and useful. The embedment of AR in science could bring an awe-inspiring transformation on learners' viewpoint towards the respective subject matters. Augmented Reality is able to present the real and virtual learning experience with the addition of multiple media without replacing the real environment. Due to the unique feature of AR, it attracts the mass attention of researchers to implement AR in science learning. This impressive technology offers learners with the ultimate visualization and provides an astonishing and transparent learning experience by bringing to light the unseen perspective of the learning content. This paper will attract the attention of researchers in the related field as well as academicians in the related discipline. This paper aims to propose several related theoretical guidance that could be applied in science motivation to transform the learning in an effective way.

  15. A Brief History of the Soil Science Society of America

    Science.gov (United States)

    Brevik, Eric C.

    2013-04-01

    The Soil Science Society of America (SSSA) was officially born on November 18, 1936 at the Mayflower Hotel in Washington, D.C. with Richard Bradfield as the first President. SSSA was created from the merger of the American Soil Survey Association and the Soils Section of American Society of Agronomy (ASA). Six sections were established: 1) physics, 2) chemistry, 3) microbiology, 4) fertility, 5) morphology, and 6) technology, and total membership was less than 200. The first issue of SSSA Journal, then called SSSA Proceedings, published 87 items totaling 526 pages. The first recorded bank balance for SSSA was at the end of the 1937-38 fiscal year, and showed the Society to be worth 1,300.03. The Soils Section of ASA became the official American section of the International Society of Soil Science in 1934, and the new SSSA inherited that distinction which it retains to this day. SSSA has grown significantly since those early days. The original six sections have grown to 11 divisions, and some of those divisions have changed their names to reflect changes occurring within soil science. For example, the original section 5, morphology, is now Division S05 - Pedology after spending many years under other names such as Division V - Soil Classification and Division S-5 - Soil Genesis, Morphology, and Classification. SSSA was incorporated in the State of Wisconsin, USA on 22 January, 1952. Several awards have been developed to recognize achievement in the field of soil science, including the SSSA Presidential Award, Don and Betty Kirkham Soil Physics Award, Emil Truog Soil Science Award, International Soil Science Award, Irrometer Professional Certification Service Award, L.R. Ahuja Ag Systems Modeling Award, Marion L. and Chrystie M. Jackson Soil Science Award, Soil Science Applied Research Award, Soil Science Distinguished Service Award, Soil Science Education Award, Soil Science Industry and Professional Leadership Award, Soil Science Research Award, and SSSA Early

    This report is the latest in a continuing series that highlights the recent technical accomplishments associated with the work being performed within the Materials and Process Sciences Center. Our research and development activities primarily address the materials-engineering needs of Sandia's Nuclear-Weapons (NW) program. In addition, we have significant efforts that support programs managed by the other laboratory business units. Our wide range of activities occurs within six thematic areas: Materials Aging and Reliability, Scientifically Engineered Materials, Materials Processing, Materials Characterization, Materials for Microsystems, and Materials Modeling and Simulation. We believe these highlights collectively demonstrate the importance that a strong materials-science base has on the ultimate success of the NW program and the overall DOE technology portfolio.

  20. Obituary: Cornell H. Mayer, 1921-2005

    2006-12-01

    Cornell (Connie) H. Mayer, a pioneer of radio astronomy, died on 19 November 2005 of congestive heart failure at his home in Mt. Vernon, Virginia. He was eighty-three. Cornell Mayer was born in Ossian, Iowa on 10 December 1921. After graduating from the University of Iowa in 1943, he joined the Navy during World War II and was stationed at the Naval Research Laboratory (NRL) in Washington, DC. There he assisted Fred T. Haddock in the development of the first radar antenna inside a submarine periscope. This device has been credited with shortening the war in the Pacific because of the number of Japanese ships that were sunk with its aid. With Haddock, Connie also discovered centimeter-wave radio bursts from the sun coincident with solar flares. They made the first detection of thermal radio emission from the Orion nebula and other galactic HII regions. They also detected extragalactic objects and thus initiated the important field of centimeter-wave astronomy. Their observations were made with a 50-foot parabolic reflector on a gun mount located on the roof of one of the NRL buildings. This telescope had the world's highest radio resolving power for many years. With Haddock's departure to the University of Michigan in 1956 to create a new radio observatory there, Connie became head of a group in the Radio Astronomy Branch at NRL, where he remained until his retirement in 1980. Much of his work involved the measurement of planetary temperatures by analysis of radio emissions. By making technical innovations in instrumentation--such as replacing disc choppers with a ferrite switch to compare the sky and reference load, or using argon gas tubes for calibration--Connie greatly improved the performance of his equipment. This resulted in the discovery of an astonishing, 600oC surface temperature of Venus, which contradicted the widespread notion that Venus was similar to the Earth and potentially habitable. In spite of the extraordinarily careful and systematic way that

    Full Text Available Background: Predictive Models are an important tool in event predicting and health planning. Despite this, there are few works focusing this area. Thus, the analysis of the real benefits of these models in Health Sciences is necessary to be performed. Results: Predictive techniques largely evolved in second half of XX century. The development of AR, MA, ARMA, ARIMA and SARIMA models, through Box-Jenkins methodology, constitute a robust conjunct of mechanisms able to help in solution of epidemiological modeling problems, mainly in Health Sciences, once it allows to evaluate individual characteristics of living beings and its correlation with pathologies in the same space-time. Nevertheless, AR, MA and ARMA does not have tendency in seasonality, which weakens the analysis. Conclusions: To predict the natural history of endemic/epidemic and its health-disease processes in a determined population is a sine que non condition to its adequate management in Public Health context and in adoption of affirmative measures concerning health promotion. Thus, the predictive models, with emphasis in ARIMA, SARIMA, Artificial Neural Networks and Formalism of Copulas are alternatives that can be feasible.

    “It is essential that world leaders agree on emissions reductions needed to combat negative consequences of anthropogenic climate change,” national science academies from 13 countries declared in a joint statement issued on 11 June. The statement, issued by the academies of the G8 countries—including England, France, Russia, and the United States—and five other countries (Brazil, China, India, Mexico, and South Africa), came in advance of a G8 meeting in Italy in July and prior to United Nations Framework Convention on Climate Change (UNFCCC) negotiations in Denmark in December. “The G8+5 should lead the transition to an energy-efficient and low-carbon world economy, and foster innovation and research and development for both mitigation and adaptation technologies,” the statement noted. The academies urged governments to agree at the UNFCCC negotiations to adopt a long-term global goal and short-term emissions reduction targets so that by 2050 global emissions would be reduced by about 50% from 1990 levels.

  4. CORNELL: CLEO's counters

    Particle identification by measuring ionization is complicated by the fact that the energy lost to ionization in passing through matter has large fluctuations, first calculated by Landau. These large fluctuations imply that many measurements must be made in order to determine the most probable ionization value that is characteristic of the particle type. The JADE chamber at PETRA and the TPC chamber at PEP measure both the ionization and the momenta of tracks in the same device. In the CLEO experiment at Cornell's CESR ring, ionization is measured in dedicated energy loss counters contained in each of the eight octants surrounding the drift chamber and superconducting coil. The last of these were installed in the summer of 1981, replacing Cherenkov counters that were used while the energy loss counters were being developed and built

    Development of rf superconductivity for high energy accelerators has been a robust activity at the Cornell Laboratory of Nuclear Studies (LNS) for many years. In order to realize the potential of rf superconductivity, a two-pronged approach has been followed. On the one hand accelerator applications were selected where the existing state-of-the art of superconducting rf is competitive with alternate technologies, then LNS engaged in a program to design, construct and test suitable superconducting cavities, culminating in a full system test in an operating accelerator. On the second front the discovery and invention of ideas, techniques and materials required to make superconducting rf devices approach the ideal in performance has been aggressively pursued. Starting with the development of superconducting cavities for high energy electron synchrotrons, the technology was extended to high energy e + e - storage rings. The LE5 cavity design has now been adopted for use in the Continuous Electron Beam Accelerator Facility (CEBAF). When completed, this project will be one of the largest applications of SRF technology, using 440 LE5 modules[4]. In the last two years, the cavity design and the technology have been transferred to industry and CEBAF. Cornell has tested the early industrial prototypes and cavity pairs. LNS has developed, in collaboration with CEBAF, designs and procedures for cavity pair and cryomodule assembly and testing. Advanced research for future electron accelerators is badly needed if particle physicists hope to expand the energy frontier. Superconducting cavity technology continues to offer attractive opportunities for further advances in achievable voltage at reasonable cost for future accelerators. For Nb, the full potential implies an order of magnitude increase over current capabilities. 20 references, 11 figures

    Current university undergraduate students in environmental sciences and engineering are the next generation of environmental protection practitioners. Recognizing this, Cornell's Biological and Environmental Engineering department has developed a popular class, Watershed Engineering (BEE 473), specifically designed to bridge the too-common gap between water resources policy and state-of-art science and technology. Weekly homework assignments are to design real-life solutions to actual water resources problems, often with the objective of applying storm water policies to local situations. Where appropriate, usually in conjunction with recent amendments to the Federal Clean Water Act, this course introduces water resource protection tools and concepts developed in the Cornell Soil and Water Lab. Here we present several examples of how we build bridges between university classrooms and the complex world of water resources policy.

  9. Making good use of synchrotron radiation, The role of CHESS at Cornell and as a national facility

    Atom smashers is what the New York Times calls them when it publishes a piece about particle accelerators. Historically, particle accelerators were in fact used to break apart atoms, but modern machines do more exotic things. One of them is a spin-off of acceleration - the production of high-energy synchrotron radiation. Once considered a nuisance, this radiation has become valuable in almost every field of science and engineering. It is the basis of a national facility, the Cornell High Energy Synchrotron Source (CHESS), that operates in conjunction with the Cornell Electron Storage Ring (CESR). CHESS provides the highest-energy synchrotron radiation available in the United States

    International Nuclear Information System (INIS)

    1993-01-01

    The CLEO collaboration at Cornell's CESR electron-positron storage ring has discovered a rare type of B meson decay in which only a high energy photon and a K* meson are produced. These decays provide the first unambiguous evidence for an alternative route for heavy quark decay that has been given the whimsical name ''penguin diagram''. In the mid-1970s penguin diagrams were proposed to explain the puzzling strangeness quantum number selection rules in the decay of K mesons. At the same time it was realized that penguin diagrams could also be important in the CP violation seen in neutral K meson decay. CP violation, an asymmetry between matter and antimatter, is an essential ingredient in understanding why there is much more matter than antimatter in the universe. CP violation introduces a definite direction to the arrow of time, which could otherwise point equally forwards or backwards. In addition, penguin decays are very sensitive to some extensions of the Standard Model of weak decay. Although penguin diagrams were first proposed to explain an effect in K meson decay, the K system gives no unique signature for them, and verification of penguin processes meant looking elsewhere. In the Standard Model, quarks decay under the influence of the weak force, emitting a W boson. Since the W is charged, the charge of the initial quark differs from that of the final quark, so the charge of the quark changes as well as its flavour

    The mission of the Energy Materials Center at Cornell (emc2) was to achieve a detailed understanding, via a combination of synthesis of new materials, experimental and computational approaches, of how the nature, structure, and dynamics of nanostructured interfaces affect energy conversion and storage with emphasis on fuel cells, batteries and supercapacitors. Our research on these systems was organized around a full system strategy for; the development and improved performance of materials for both electrodes at which storage or conversion occurs; understanding their internal interfaces, such as SEI layers in batteries and electrocatalyst supports in fuel cells, and methods for structuring them to enable high mass transport as well as high ionic and electronic conductivity; development of ion-conducting electrolytes for batteries and fuel cells (separately) and other separator components, as needed; and development of methods for the characterization of these systems under operating conditions (operando methods) Generally, our work took industry and DOE report findings of current materials as a point of departure to focus on novel material sets for improved performance. In addition, some of our work focused on studying existing materials, for example observing battery solvent degradation, fuel cell catalyst coarsening or monitoring lithium dendrite growth, employing in operando methods developed within the center.

    This paper outlines the RF superconductivity research and development work that has taken place at Cornell Laboratory of Nuclear Studies over the past years. The work that has been performed since the last RF superconductivity workshop is emphasized together with a discussion of the direction of future efforts. Past work is summarized first, focusing on research and development activities in the area of RF superconductivity. Superconducting TeV linear collider is then discussed focusing on the application of superconducting RF to a future TeV linear collider. Linear collider structure development is then described centering on the development of a simpler (thereby cheaper) structure for a TeV linear collider. B-factory with superconducting RF is outlined focusing on the formulation of a conceptual design for a B-factory. B-factory structure development is discussed in relation to the advancement in the capability of SC cavities to carry beam currents of several amperes necessary for a high luminosity storage ring. High gradients are discussed as the key to the realization of a high energy superconducting linac or a superconducting RF B-factory. (N.K.)

  15. CORNELL: Bunch trains provide higher luminosity

    International Nuclear Information System (INIS)

    Anon.

    1995-01-01

    The new colliding beam technique - ''bunch trains'' - at Cornell's electron-positron Storage Ring (CESR) has led to a new world record for colliding beam luminosity - 3.3 x 10 32 cm -2 s -1 . In the bid to increase reaction rate for any particular process, this luminosity is pushed as high as possible. Once all other luminosityincreasing cards have been played, the only practical way of making a large gain in luminosity is to increase the frequency of bunch-bunch collisions by increasing the number of bunches stored in the ring. However this is not without its own problems: • If the two beams travel the same orbit, the n bunches in one beam collide with the n bunches of the other at 2n points around the ring, and the resulting cumulative nonlinear beam-beam effect (tune shift) severely limits the luminosity attainable at any interaction point. • The destabilizing wakefield effects of bunches on each other increase as the number of bunches increases and the spacing between them decreases. • The synchrotron radiation emitted by the beams becomes a severe problem as the total beam current is raised: to overcome these effects means supplying radiofrequency power to maintain the beam energy, carrying away heat from the vacuum chamber walls, pumping out desorbed gases, and controlling Xray backgrounds in the experiment. In 1979, CESR was designed to run with a single bunch of electrons and a single bunch of positrons circulating on the same orbit and colliding head-on at two diametrically opposite points in the ring, where the CLEO and CUSB experiments were then located. Ideally one could store multiple bunches and solve the multiple collision point problem by using separate rings for the two beams, as in the CERN ISR proton-proton collider and in the original DORIS two-ring configuration at DESY, Hamburg, making the two beams intersect only at the experiments.

    Higher order mode (HOM) couplers are integral parts of a superconducting accelerator cavity. The damping which the couplers must provide is dictated by the frequency and shunt impedance of the cavity modes as well as by the stability requirements of the accelerator incorporating the cavities. Cornell's 5-cell 1500 MHz elliptical cavity was designed for use in a 50 x 50 GeV electron-positron storage ring with a total beam current of 3.5 mA (CESR-II). HOM couplers for the Cornell cavity were designed and evaluated with this machine in mind. The development of these couplers is described in this paper. 8 references, 8 figures

    1984-01-01

    The Cornell Mark II TRIGA reactor has been a principal facility for instruction and research in nuclear science and engineering at Cornell, and it has been extensively used by other departments at Cornell and by nearby universities and industries. Initially the fuel was low hydride, 8.5w/o 19%-enriched, aluminum clad; in 1974 it was changed to high-hydride, stainless-steel-clad. The maximum power has been 100 kW, with pulses to $2, and operation has been on a one-shift demand basis. Annual energy generation of 50 MWH has been typical. Standard features include a 4-inch tangential port and our 6-inch radial ports, a thermal column with hohlraum and vertical access, a central thimble, a 'rabbit', and a set of dry irradiation tubes, replacing the 'Lazy Susan'. The license was renewed and amended in November 1983; the new limits are 500 kW and $3 pulses. Physical changes to the facility included addition of a water-to-water heat exchanger and of a diffuser at the water outlet ∼ 60 cm above the core. The flow rate is 300 liters per minute in the primary (reactor) side of the heat exchanger. The temperature of the chilled water entering the secondary of the exchanger is ∼ 12?C; its flow rate is adjusted by a servo-controlled by-pass valve to maintain the desired range of pool water temperature. Steps taken to go to higher power included rearrangement of fuel elements to increase excess reactivity, recalibration of control rods, and power vs ion chamber current calibrations at successively higher power by comparing the rate of rise of pool temperature with a known rate using electrical heating elements. Steady-state operation has been done up to 480 kW (nominal) but pulsing at the newly allowed higher levels has not been tested as yet

    1992-01-01

    The cold neutron beam facility at the Cornell University TRIGA Mark II reactor will begin operational testing in early 1993. It is designed to provide a low background subthermal neutron beam that is as free as possible of fast neutrons and gamma rays for applied research and graduate-level instruction. The Cornell cold neutron source differs from the more conventional types of cold sources in that it is inherently safer because it uses a safe handling material (mesitylene) as the moderator instead of hydrogen or methane, avoids the circulation of cryogenic fluids by removing heat from the system by conduction through a 99.99% pure copper rod attached to a cryogenic refrigerator, and is much smaller in its size and loads. The design details and potential hazards are described, where it is concluded that no credible accident involving the cold source could cause damage to the reactor or personnel, or cause release of radioactivity.

    2018-01-01

    The Cornell Kitchen (1950-55) was produced at Cornell University by a multidisciplinary team with expertise in home economics, engineering, architecture, and psychology. It promised to deliver rational design, functional principles, aesthetic appeal, and emotional satisfaction in one prefabricated, easy-to-install package. This article sets out the kitchen's history from its design to its field-testing phase to its impact on postwar kitchens. It argues that the kitchen represents an important effort to approach housing in a more scientific way; scientific methods were deployed to understand both the physical and socio-psychological problems of dwelling. The project also sought to introduce a specific model for leveraging housing research into the real world, partnering with industry to mass produce scientific designs. Social scientific methods were hence used to create not only more livable but also more saleable products in an effort to appeal to manufacturers and consumers alike.

    Fraser, D R; McGregor, D D; Grohn, Y T

    The Cornell Leadership Program at Cornell University, usa, aims to assist talented veterinary students to embark on careers in research, academia, government agencies or industry. Over 400 students have participated since the Program began in 1990 and their subsequent careers have been followed. In this study, five sources of data were analysed: application documents of the participants; audio recordings of interviews with each participant from 2000 to 2007; annual tracking records of alumni after graduating with a veterinary degree; spontaneous comments from alumni about how the Program influenced their career plans; and a list of published scientific papers by alumni. Analysis revealed that about 50 per cent of veterinary graduates were establishing themselves in careers envisaged by the Program, although many of them experienced conflicts between a vocational commitment to clinical practice and a desire to solve problems through research. Many alumni asserted that the Program had influenced their career plans, but they had difficulty in accepting that rigorous scientific training was more important in acquiring research skills than working directly on a veterinary research problem. One career of great appeal to alumni was that of veterinary translational science, in which disease mechanisms are defined through fundamental research. It is concluded from the data that there are three challenging concepts for recently qualified veterinarians aiming to advance the knowledge of animal disease: research careers are satisfying and rewarding for veterinarians; a deep understanding of the chosen field of research is needed; and a high standard of scientific training is required to become an effective veterinary scientist.

  9. Programs with societal benefits at the Cornell University TRIGA reactor

    1993-01-01

    In its 30 yr of operation, the Cornell TRIGA reactor has been used for many educational and research programs that provide general benefits to society. In addition to supporting graduate-level education of nuclear scientists and engineers, it has been extensively used in undergraduate and graduate courses and research by nonspecialists and, through the medium of tours, in education of the general public. Some educational functions have been described previously. In this paper, examples are presented of research of societal interest in nonnuclear fields. The first two rely mainly on radiography, and the remaining five on neutron activation analysis (NAA)

  10. Cornell Fuel Cell Institute: Materials Discovery to Enable Fuel Cell Technologies

    Energy Technology Data Exchange (ETDEWEB)

    Abruna, H.D.; DiSalvo, Francis J.

    2012-06-29

    The discovery and understanding of new, improved materials to advance fuel cell technology are the objectives of the Cornell Fuel Cell Institute (CFCI) research program. CFCI was initially formed in 2003. This report highlights the accomplishments from 2006-2009. Many of the grand challenges in energy science and technology are based on the need for materials with greatly improved or even revolutionary properties and performance. This is certainly true for fuel cells, which have the promise of being highly efficient in the conversion of chemical energy to electrical energy. Fuel cells offer the possibility of efficiencies perhaps up to 90 % based on the free energy of reaction. Here, the challenges are clearly in the materials used to construct the heart of the fuel cell: the membrane electrode assembly (MEA). The MEA consists of two electrodes separated by an ionically conducting membrane. Each electrode is a nanocomposite of electronically conducting catalyst support, ionic conductor and open porosity, that together form three percolation networks that must connect to each catalyst nanoparticle; otherwise the catalyst is inactive. This report highlights the findings of the three years completing the CFCI funding, and incudes developments in materials for electrocatalyts, catalyst supports, materials with structured and functional porosity for electrodes, and novel electrolyte membranes. The report also discusses developments at understanding electrocatalytic mechanisms, especially on novel catalyst surfaces, plus in situ characterization techniques and contributions from theory. Much of the research of the CFCI continues within the Energy Materials Center at Cornell (emc2), a DOE funded, Office of Science Energy Frontier Research Center (EFRC).

  11. Operational experience with nanocoulomb bunch charges in the Cornell photoinjector

    2015-08-01

    Full Text Available Characterization of 9–9.5 MeV electron beams produced in the dc-gun based Cornell photoinjector is given for bunch charges ranging from 20 pC to 2 nC. Comparison of the measured emittances and longitudinal current profiles to optimized 3D space charge simulations yields excellent agreement for bunch charges up to 1 nC when the measured laser distribution is used to generate initial particle distributions in simulation. Analysis of the scaling of the measured emittance with bunch charge shows that the emittance scales roughly as the square root of the bunch charge up to 300 pC, above which the trend becomes linear. These measurements demonstrate that the Cornell photoinjector can produce cathode emittance dominated beams meeting the emittance and peak current specifications for next generation free electron lasers operating at high repetition rate. In addition, the 1 and 2 nC results are relevant to the electron ion collider community.

    Cortés, Manuel E; Del Río, Juan Pablo; Vigil, Pilar

    2015-02-01

    The objective of this editorial is to show that a harmonious relationship between science and faith is possible, as exemplified by great saints of the Catholic Church. It begins with the definitions of science and faith, followed by an explanation of the apparent conflict between them. A few saints that constitute an example that a fruitful relationship between these two seemingly opposed realities has been possible are Saint Albert the Great, Saint John of the Cross, Saint Giuseppe Moscati, and Saint Edith Stein, among others, and this editorial highlights their deep contributions to the dialogue between faith and reason. This editorial ends with a brief discussion on whether it is possible to be both a scientist and a man of faith.

    1997-01-01

    The cold source for a guided neutron beam has been installed in a Cornell TRIGA beamport and has successfully undergone thermal tests up to full power (normally 480 kW). Tests to date (8/1/96) include spectral and yield measurements at 10 kW with the first three meters of the 2-cm by 5-cm Ni-on-glass guide in place. A 110-cm 3 Al chamber, located 17 cm from the core, contains solid mesitylene and is cooled by conduction through a 269-cm long Cu rod connected to a cryorefrigerator outside the reactor shield. Distributions of flux per unit velocity have been measured at 10 kW by time-of-flight. Anticipated properties of the complete 13 m long beam at full power are discussed. (author)

  19. A BRIEF HISTORY OF THE INTRODUCTION OF MODERN SCIENCE TO PORTUGAL DURING THE 18th CENTURY

    Directory of Open Access Journals (Sweden)

    TERESA CASTELÃO-LAWLESS

    2016-05-01

    Full Text Available The focus of this article is on the role played by members of the Society of Jesus, the Order of the Oratorians, and the Jewish community in the introduction of Modern science in Portugal during the 18th century. The record of their publications prove, contrary to common stereotypes on the permanent conflict between science and religion, that they all embraced Modern, anti-Aristotelian, natural philosophy fairly equally and unreservedly. The rhetoric they used in manuscript Dedications to prospective patrons also show that they were actively engaged in shifting Modern science from a context of private consumption to one of public circulation. I acknowledgethat the dissemination of Modern science in Portugal during the 1700’s was slow and protracted. This phenomenon, however, was not, as typically argued, caused by scientific conservatism on the part of the religious Orders, or the ill will of patrons of the sciences, but by the political motives of enlightened despots João V, José I and his Prime-Minister the Marquis of Pombal.

    Full Text Available For decades, cognitive sciences and psychoanalysis have been ignored each other for a mutual distrust, producing in scholars of both disciplines a progressive mutual ignorance and misunderstanding about their developments. The latest studies of cognitive sciences on the role of emotions have allowed a partial approach to psychoanalysis. But above all, recent studies in neuroscience on the emotional basis of all mental processes, about the formation of the subjectivity, about identity and sense of self (neuro psychoanalysis, are opening up a horizon of integration between the three different sciences. In this perspective the epigenetics is playing a fundamental role, that the Author hopes will produce significant developments from a social and anthropological point of view.

    2004-10-01

    Full Text Available Science fairs at one time started out with an interest of increasing participation in the sciences. But as time has passed, the definition of science has been narrowed to the point where any possible social science project has been eliminated in favor of the bench sciences only. Even here, natural curiosity of students has been deemphasized. It is not surprising that science majors in the USA are becoming fewer and fewer given the narrowing of the disciplines. Young people are discouraged from majoring in science by the science establishment.

    2013-04-01

    The Brazilian Soil Science Society (SBCS) is one of the oldest scientific societies in Brazil. It was created in October 1947 during the 1st Brazilian Meeting of Soil Science held at the headquarters of the Agricultural Chemistry Institute of Rio de Janeiro, at present the Soils Institute of the Brazilian Agricultural Research Centre. Its origin lies within the Interamerican Conference of Agriculture, Caracas, 1945, the 2nd Pan American Congress of Mining and Geology, Petropolis, Rio de Janeiro, 1946 and the 5th Brazilian Congress of Chemistry, Porto Alegre, 1947. Its first president was Álvaro Barcelos Fagundes, who was the only Brazilian participant at the 1st International Congress of Soil Science and Transcontinental Excursion held in United States of America, in 1927. At that time he was engaged in research work at the New Jersey Agricultural Experiment Station, at the Rutgers University where he did a doctorate under the guidance of Professor Selman Waksman. The society started with 47 members and presently has nearly 900 members. In its first phase the Brazilian Soil Science Society was housed at the Agricultural Chemistry Institute in Rio de Janeiro and its main activity was the biannual Brazilian Congress of Soil Science. In 1975 its headquarters moved to the Agronomic Institute of Campinas with the creation of its executive board and the start of publication of the Brazilian Journal of Soil Science (1977) as well as the society bulletin (1976). In 1997 its executive office moved to the Soils Department at the Federal University of Viçosa. Nowadays it has a structure similar to the one from the IUSS: the society is organized in four divisions (Soil in space and time, Soils properties and processes, Soil use and management and Soil, environment and society) which encompass 14 technical commissions and eight State or Regional nuclei. The Brazilian Congresses of Soil Science happen without interruption since 1947. The first one had had 72 participants that

    An ampfion hybrid diode, previously run on the HYDRAMITE accelerator at Sandia National Laboratories has recently been installed on the Cornell LION accelerator (1 TW, 1.8 MV, 40 ns pulse). The ampfion hybrid diode is magnetically insulated by means of a field coil in series with the cathode structure of the diode. An epoxy dielectric flashboard on the anode provides an anode plasma to supply the extracted ions. The diode has a geometric focal length of 20 cm. The experiment is equipped with plasma erosion opening switches on the anode stock to eliminate prepulse and improve the generator voltage risetime. Diagnostics include magnetic pickup loops to measure currents in the diode structure and non-neutral beam currents, biased charge collectors, and damage targets. An alpha particle pin hole camera utilizing the p,α reaction of fast (>500 kV) protons on boron or lithium is being developed to measure focus quality and proton current. Plastic track detector will be used to image the alpha particles coming from a boron or lithium target. A second pin hole camera uses a plastic scintillator and light detector to give time resolved focused ion intensity

    Both the history of biolocomotion (later to become motion analysis/biomechanics) and of electrology (later kinesiological electromyography) are to be traced back to approximatively the same period in the second half of the seventeenth century. The major contributors to these emergent sciences were Swammerdam in 1658 and Borelli in 1680. Some 150 years later, electrophysiological methods were derived and motion-cinephotography was developed from their pioneering work. Subsequently, use was made of motion analysis by means of cinephotography, forming a basis for biomechanics. The work of Marey in 1873 in particular stimulated the multidisciplinary study of human activity, providing models for contemporary sports scientists working in applied settings. The link between theory and practice in motion sciences and the multidisciplinary model of Marey were the motive and the example for establishing the Working Group of Biomechanics in the 1960s. This body has gone through a series of progressive developments, culminating in the approval of the World Commission of Science and Sports as a service group of the International Council for Sport Science and Physical Education (recognized by UNESCO).

  11. Soil Health Assessment Approaches and the Cornell Framework

    Science.gov (United States)

    van Es, Harold

    2016-04-01

    Soil health constraints beyond nutrient limitations and excesses currently limit agroecosystem productivity and sustainability, resilience to drought and extreme rainfall, and progress in soil and water conservation. With mounting pressure to produce food, feed, fiber, and even fuel for an increasing population, the concept of soil health is gaining national and international attention. Multiple regional, national, and global efforts are now leveraging that work to reach new stakeholder audiences, so that soil health management is expanding into mainstream agriculture. Each grower is generally faced with a unique situation in the choice of management options to address soil health constraints and each system affords its own set of opportunities or limitations to soil management. A more comprehensive understanding of soil health status can better guide farmers' management decisions. Until recently, there has not been a formalized decision making process for implementing a soil health management system that alleviates field-specific constrains identified through standard measurements and then maintains improved soil health. This presentation will discuss current US-based efforts related to soil health assessment, including efforts to build national consensus on appropriate methods for simple (inexpensive) and comprehensive tests. This includes the Cornell Soil Health Management Planning and Implementation Framework. The most relevant components of the framework are 1) measurement of indicators that represent critical soil processes, 2) scoring of measured values that allows for interpretation, and 3) linkage of identified constraints with management practices. Land managers can monitor changes over time through further assessment, and adapt management practices to achieve chosen goals. We will discuss the full tests and approaches for simplification.

    2013-04-01

    Medical records of 1407 cats with dermatologic diagnoses made at Cornell University teaching hospital from 1988 to 2003 were tabulated. We expressed the diagnoses as counts, percentages of the cats with dermatologic disease (1407) and percentages of all cats seen at the university hospital (22,135) during the same period. A total of 1887 diagnoses were made in the 1407 cats. We compared the age, sex and breed group of our cases with all those 22,135 cats in ('1-by-c') χ(2) tests in which the hospital population was considered a standard (rather than a 'sample'). The 10 most common dermatoses, their counts, and the proportions of dermatologic diagnoses and of the total cat population that the cats with these dermatoses represented were: allergy (298; 15.8%; 1.35%), atopic dermatitis (194; 10.3%; 0.88%), bacterial folliculitis/furunculosis (189; 10.0%; 0.85%), otodectic mange (115; 6.1%; 0.52%), flea infestation (99; 5.2%; 0.45%), feline acne (74; 3.9%; 0.33%), flea-bite allergy (70; 3.7%; 0.32%), cutaneous adverse drug reaction (56; 3.0%; 0.25%), idiopathic eosinophilic-granuloma complex (55; 2.9%; 0.25%) and abscess (51; 2.7%; 0.23%). Allergies of all types, combined, accounted for 32.7% of all the feline dermatoses. Relative to the standard of the total hospital population, cats <2 years old and females (both intact and spayed) were significantly under-represented (all P≤0.001) in the dermatologic case series. In contrast, Himalayans (compared with domestic short- or longhair, Persian, Siamese and other breeds) and males (both intact and neutered) were significantly over-represented (all P ≤0.001).

  13. Zaccaria Lilio and the shape of the earth: A brief response to Allegro's "Flat earth science".

    Science.gov (United States)

    Nothaft, C Philipp E

    2017-12-01

    This is a response to James J. Allegro's article "The Bottom of the Universe: Flat Earth Science in the Age of Encounter," published in Volume 55, Number 1, of this journal. Against the solid consensus of modern scholars, Allegro contends that the decades around 1500 saw a resurgence of popular and learned doubts about the existence of a southern hemisphere and the concept of a spherical earth more generally. It can be shown that a substantial part of Allegro's argument rests on an erroneous reading of his main textual witness, Zaccaria Lilio's Contra Antipodes (1496), and on a failure adequately to place this source in the context of the cosmographical debate of the late fifteenth and early sixteenth centuries. Once this context is taken into account, the notion that Lilio was a flat-earther falls flat.

    2017-09-01

    Metamaterials, which enable us to realize novel physical effects that cannot be achieved using natural materials, have been extensively studied in recent years and significant progress has been made, especially in the field of optics. This game-changing concept has also initiated a rich variety of research activity in vacuum electronics. Here we review the recent development of metamaterial-based vacuum electronics for terahertz (THz) and microwave science and technology. The reversed Cherenkov radiation (RCR) in double-negative (DNG) metamaterials predicted by Veselago back in the 1960s has been experimentally verified in the microwave frequency range by utilizing specially designed DNG metamaterials. The interaction of an electron beam (e-beam) with DNG metamaterials may lead to the realization of novel applications such as microwave and THz radiation sources, accelerators, and even the visualization of invisibility cloaks. Smith-Purcell radiation (SPR) has recently received renewed interest owing to the development of metamaterials and the concept of spoof surface plasmon polaritons, as discussed in this review, and recent results on e-beam-induced directional and wide-band THz radiation with sharp multiple peaks from a graded grating, as well as directional and monochromatic special SPR and their possible application to THz orotron devices, are also reviewed.

  16. Seeking missing pieces in science concept assessments: Reevaluating the Brief Electricity and Magnetism Assessment through Rasch analysis

    Science.gov (United States)

    Ding, Lin

    2014-02-01

    Discipline-based science concept assessments are powerful tools to measure learners' disciplinary core ideas. Among many such assessments, the Brief Electricity and Magnetism Assessment (BEMA) has been broadly used to gauge student conceptions of key electricity and magnetism (E&M) topics in college-level introductory physics courses. Differing from typical concept inventories that focus only on one topic of a subject area, BEMA covers a broad range of topics in the electromagnetism domain. In spite of this fact, prior studies exclusively used a single aggregate score to represent individual students' overall understanding of E&M without explicating the construct of this assessment. Additionally, BEMA has been used to compare traditional physics courses with a reformed course entitled Matter and Interactions (M&I). While prior findings were in favor of M&I, no empirical evidence was sought to rule out possible differential functioning of BEMA that may have inadvertently advantaged M&I students. In this study, we used Rasch analysis to seek two missing pieces regarding the construct and differential functioning of BEMA. Results suggest that although BEMA items generally can function together to measure the same construct of application and analysis of E&M concepts, several items may need further revision. Additionally, items that demonstrate differential functioning for the two courses are detected. Issues such as item contextual features and student familiarity with question settings may underlie these findings. This study highlights often overlooked threats in science concept assessments and provides an exemplar for using evidence-based reasoning to make valid inferences and arguments.

Patients and methods: A cross-sectional study was conducted of 84 elderly residents (46 women, 38 men, age range 60–94 years in a long-term residential home setting in Thailand between March and June 2011. The selected residents went through a comprehensive geriatric assessment that included use of the Mini-Mental State Examination, Mini-International Neuropsychiatric Interview, and CSDD instruments. Intraclass correlation (ICC was calculated in order to establish the level of agreement between the residents and caregivers, in light of the residents' cognitive status. Confirmatory factor analysis (CFA was adopted to evaluate the alternative CSDD models. Results: The CSDD yielded a high internal consistency (Cronbach's alpha = 0.87 and moderate agreement between residents and caregivers (ICC = 0.55; however, it was stronger in cognitively impaired subjects (ICC = 0.71. CFA revealed that there was no difference between the four-factor model, in which factors A (mood-related signs and E (ideational disturbance were collapsed into a single factor, and the five-factor model as per the original theoretical construct. Both models were found to be similar, and displayed a poor fit. Conclusion: The CSDD demonstrated a moderate level of interrater agreement between residents and caregivers, and was more reliable when used with cognitively impaired residents. CFA indicated a poorly fitting model in this sample. Keywords: Cornell Scale for Depression in Dementia (CSDD, factor structure

  6. Electron cloud dynamics in the Cornell Electron Storage Ring Test Accelerator wiggler

    Directory of Open Access Journals (Sweden)

    C. M. Celata

    2011-04-01

    Full Text Available The interference of stray electrons (also called “electron clouds” with accelerator beams is important in modern intense-beam accelerators, especially those with beams of positive charge. In magnetic wigglers, used, for instance, for transverse emittance damping, the intense synchrotron radiation produced by the beam can generate an electron cloud of relatively high density. In this paper the complicated dynamics of electron clouds in wigglers is examined using the example of a wiggler in the Cornell Electron Storage Ring Test Accelerator experiment at the Cornell Electron Storage Ring. Three-dimensional particle-in-cell simulations with the WARP-POSINST computer code show different density and dynamics for the electron cloud at locations near the maxima of the vertical wiggler field when compared to locations near the minima. Dynamics in these regions, the electron cloud distribution vs longitudinal position, and the beam coherent tune shift caused by the wiggler electron cloud will be discussed.

    The Cornell High Energy Synchrotron Source (CHESS) is a user-oriented National Facility that provides state-of-the-art synchrotron radiation facilities to scientists worldwide. With major new funding in 1999, we now have 5 ongoing upgrade and expansion projects: 1) a new building addition that will house a new wiggler beamline (CHESS G-line) with three new experimental stations; 2) a new more powerful wiggler source for both A and G beamlines; 3) an upgrade to the A-line optics for better heat load handling and focussing; 4) a rebuild of the F-cave optics room with new optics to handle higher machine current; and 5) a renovation to the user laboratory space surrounding the F1 and F2 crystallography stations. We expect these upgrades and a new G line Cornell faculty collaborating group to raise the level of excitement and productivity at CHESS for many years to come

    Full Text Available Paul Cornell’s work for the ‘Big Two’ U.S. comic publishers transfers a distinctly British (mostly English sensibility into a field where cues normally revolve around American cultural iconography and values. The key to his authorship is Cornell’s homespun method which, unlike 1970s and 1980s efforts of Marvel’s UK wing that transplanted American characters into a postcard-like Britain, explores a British dimension of the Marvel Universe that offers a challenge to the codes of that realm. Whether working with established heroes such as Captain Britain, twists on archetypes like Knight and Squire (English analogues of Batman and Robin, or superheroic ‘big guns’ like Wolverine, Cornell writes against tired, automatic canonicity. This paper mainly focuses on the directly British representations in the Cornell titles Captain Britain and MI-13 (2008-9 and Knight and Squire (2010.

    2017-11-01

    As part of long-standing efforts to promote undergraduates' success in science, researchers have investigated the instructional strategies and motivational factors that promote student learning and persistence in science coursework and majors. This study aimed to create a set of brief measures that educators and researchers can use as tools to examine the undergraduate motivational experience in science classes. To identify key motivational processes, we drew on self-determination theory (SDT), which holds that students have fundamental needs - to feel competent, related, and autonomous - that fuel their intrinsic motivation. When educational experiences meet these needs, students engage more energetically and learn more, cumulatively contributing to a positive identity as a scientist. Based on information provided by 1013 students from 8 classes in biology, chemistry, and physics, we constructed conceptually focused and psychometrically sound survey measures of three sets of motivational factors: (1) students' appraisals of their own competence, autonomy, and relatedness; (2) the quality of students' behavioural and emotional engagement in academic work; and (3) students' emerging identities as scientists, including their science identity, purpose in science, and science career plans. Using an iterative confirmatory process, we tested short item sets for unidimensionality and internal consistency, and then cross-validated them. Tests of measurement invariance showed that scales were generally comparable across disciplines. Most importantly, scales and final course grades showed correlations consistent with predictions from SDT. These measures may provide a window on the student motivational experience for educators, researchers, and interventionists who aim to improve the quality of undergraduate science teaching and learning.

    Indian capabilities in science and technology cover an impressive range of diverse disciplines, areas of competence and of applications. India's strength in basic research is recognized internationally. Successes in agriculture, health care, chemicals and pharmaceuticals, nuclear energy, astronomy and astrophysics, space technology and applications, defense research, biotechnology, electronics, information technology and oceanography are widely acknowledged. Major national achievements include very significant increase in food production, eradication or control of several diseases and increased life expectancy of our citizens. Research and development (R and D) is an inseparable part of science and technology, with India fast emerging as the global R and D hub. While these developments have been highly satisfying, one is also aware of the dramatic changes that have taken place, and continue to do so, in the practice of science, in technology development, and their relationships with, and impact on, society. Mainly remarkable is the rapidity with which science and technology is moving ahead. Science is becoming increasingly inter- and multi-disciplinary, and calls for multi-institutional and, in several cases, multi-country participation. Major experimental facilities, even in several areas of basic research, require very large material, human and intellectual resources. Science and technology have become so closely intertwined, and so reinforce each other that, to be effective, any policy needs to view them together. The continuing revolutions in the field of information and communication technology have had profound impact on the manner and speed with which scientific information becomes available, and scientific interactions take place.

    The Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was developed to assess the level of musculoskeletal discomfort among office workers related to their ergonomic situation. The primary objective of this initial study is to analyze the validity and dependability of the Malay translation of the Cornell Musculoskeletal Discomfort Questionnaire. The questionnaire was self-administered two times, with an interval of two weeks in order to evaluate the accuracy of the original findings with a retest. The study involved 115 participants. The range of Cronbach Alpha coefficient showed a considerable consistency of the items for each sub-scale (Cronbach's a > 0.95). The range of Kappa coefficients was between (ICC = 0.690-0.949, p < 0.001), (ICC = 0.801-0.979, p < 0.001) and (ICC = 0.778-0.944, p < 0.001) for frequency, severity and interference scales. This research, introduced the Malay-language version of the CMDQ (CMDQ-M) as the first formal validation of the CMDQ, and confirmed a high reliability and validity for the evaluation of musculoskeletal discomfort among the study population.

    2004-01-01

    Discussion between faculty and interested students revealed the existence of a multitude of opportunities in dairy production medicine at the College of Veterinary Medicine at Cornell University. Many of these were not well known to students, or even to some of the faculty, and the means of accessing specific learning experiences were sometimes obscure. Together, an informal group of faculty, students, and alumni set about cataloging available educational opportunities, resulting in a 31-page publication referred to as the "Opportunities Map." Essentially a student handbook for production medicine students, the Opportunities Map at Cornell helps guide the travel of food animal-interested students through the curriculum without missing the important highlights along the way. The map was originally developed to chronicle the opportunities and resources available to students, but it has also been used to foster face-to-face communications between students and faculty, to welcome incoming students with production animal interests, and to provide a baseline description for further discussion about the curriculum.

    During an energy scan at the Cornell Electron Storage Ring, with use of the Columbia University-Stony Brook NaI detector, an enhancement in sigma(e + e - →hadrons) is observed at center-of-mass energy approx.10.55 GeV. The mass and leptonic width of this state (UPSILON''') suggest that it is the 4 3 S 1 bound state of the b quark and its anitquark. After applying to the data a cut in a (pseudo) thrust variable, the natural width is measured to be GAMMA=12.6 +- 6.0 MeV, indicating that the UPSILON''' is above the threshold for BB-bar production

    A confocal X-ray fluorescence microscope was built at the Cornell High Energy Synchrotron Source (CHESS) to obtain compositional depth profiles of historic paintings. The microscope consists of a single-bounce, borosilicate monocapillary optic to focus the incident beam onto the painting and a commercial borosilicate polycapillary lens to collect the fluorescent X-rays. The resolution of the microscope was measured by scanning a variety of thin metal films through this confocal volume while monitoring the fluorescence signal. The capabilities of the technique were then probed using test paint microstructures with up to four distinct layers, each having a thickness in the range of 10-80 microns. Results from confocal XRF were compared with those from stand-alone XRF and visible light microscopy of the paint cross-sections. A large area, high-resolution scanner is currently being built to perform 3D scans on moderately sized paintings. (orig.)

    Cornell University has prototyped technology essential for any high-brightness electron ERL. This includes a DC gun and an SRF injector Linac with world-record current and normalized brightness in a bunch train, a high-current CW cryomodule for 70 MeV energy gain, a high-power beam stop, and several diagnostics tools for high-current and high-brightness beams, e.g. slid measurements for 6-D phase-space densities, a fast wire scanner for beam profiles, and beam loos diagnostics. All these are now available to equip a one-cryomodule ERL, and laboratory space has been cleared out and is radiation shielded to install this ERL at Cornell. BNL has designed a multi-turn ERL for eRHIC, where beam is transported more than 20 times around the RHIC tunnel. The number of transport lines is minimized by using two non-scaling (NS) FFAG arcs. A collaboration between BNL and Cornell has been formed to investigate the new NS-FFAG optics and the multi-turn eRHIC ERL design by building a 4-turn, one-cryomodule ERL at Cornell. It has a NS-FFAG return loop built with permanent magnets and is meant to accelerate 40 mA beam to 250 MeV.

    We developed, built and beam tested a novel, compact, in-vacuum undulator magnet based on an adjustable phase (AP) scheme. The undulator is 1 m long with a 5mm gap. It has a pure permanent magnet structure with 24.4mm period and 1.1 Tesla maximum peak field. The device consists of two planar magnet arrays mounted on rails inside of a rectangular box-like frame with 156 mm × 146 mm dimensions. The undulator magnet is enclosed in a 273 mm (10.75") diameter cylindrical vacuum vessel with a driver mechanism placed outside. In May 2012 the CHESS Compact Undulator (CCU) was installed in Cornell Electron Storage Ring and beam tested. During four weeks of dedicated run we evaluated undulator radiation properties as well as magnetic, mechanical and vacuum properties of the undulator magnet. We also studied the effect of the CCU on storage ring beam. The spectral characteristics and intensity of radiation were found to be in very good agreement with expected. The magnet demonstrated reproducibility of undulator parameter K at 1.4 × 10-4 level. It was also found that the undulator K. parameter change does not affect electron beam orbit and betatron tunes.

    Los acontecimientos de esta última década en los países del Este de Europa junto con la crisis de fundamentos y de objeto de la filosofía han dado paso a una nueva consideración de la teoría política y de su relación con la filosofía. Algunos de sus aspectos más llamativos son una revaluación de la sociedad civil, como esfera de lo público, y de las instituciones democráticas. Esta nueva concepción de la política se aleja del modelo europeo de partidos y se aproxima a las tradiciones políticas norteamericanas. El artículo intenta mostrar a través de una contrastación del pensamiento de dos teóricos neopragmatístas norteamericanos, Richard Rorty y Cornel West, la relevancia de este enfoque para la teoría política y la persistencia en él de uno de los conflictos por antonomasia del pensamiento moderno: la tensión entre democracia y liberalismo.

    The Wilson Laboratory at Cornell University has done pioneering work on the development of high energy synchrotrons. In the last decade the 12 GeV Wilson Synchrotron was the most energetic electron synchrotron in the world. In 1975 plans were formulated at the Wilson Laboratory to build a new electron-positron storage ring to cover the range from 4-8 GeV. The storage ring was to be constructed in the same tunnel as the present synchrotron and to use the latter as an injector for the ring. A novel injection feature was to be incorporated, namely, vernier phase compression. In this scheme, positron coalesence is to be performed by compressing a 30-60 bunch positron beam by tranferring individual bunches from the storage ring to the synchrotron and stacking back into the storage ring. This procedure takes advantage of the slight circumferential difference between the storage ring and the synchrotron. Positron beams of 10 mA have been achieved in CESR at the present time. The first colliding beam studies were performed in an October 1979 two-week running period at which time CHESS, the synchrotron radiation source associated with CESR, also had its first extended experience with synchrotron light.

  15. Detection and clearing of trapped ions in the high current Cornell photoinjector

    2016-03-01

    Full Text Available We have recently performed experiments to test the effectiveness of three ion-clearing strategies in the Cornell high intensity photoinjector: DC clearing electrodes, bunch gaps, and beam shaking. The photoinjector reaches a new regime of linac beam parameters where high continuous wave beam currents lead to ion trapping. Therefore ion mitigation strategies must be evaluated for this machine and other similar future high current linacs. We have developed several techniques to directly measure the residual trapped ions. Our two primary indicators of successful clearing are the amount of ion current removed by a DC clearing electrode, and the absence of bremsstrahlung radiation generated by beam-ion interactions. Measurements were taken for an electron beam with an energy of 5 MeV and continuous wave beam currents in the range of 1–20 mA. Several theoretical models have been developed to explain our data. Using them, we are able to estimate the clearing electrode voltage required for maximum ion clearing, the creation and clearing rates of the ions while employing bunch gaps, and the sinusoidal shaking frequency necessary for clearing via beam shaking. In all cases, we achieve a maximum ion clearing of at least 70% or higher, and in some cases our data is consistent with full ion clearing.

    Full Text Available We investigated the reproductive responses of Awassi ewes under Cornell alternate month accelerated lambing (CAMAL system. Ewes were randomly allocated to two experimental groups. The first group (control group consists of 20 ewes exposed to rams in September under conventional management system while the second group (CAMAL were divided into four sub-flocks contain 20 head of ewes each one were exposed to rams to obtain three lambing in two years with different breeding and lambing months. In CAMAL ewes, oestrus was synchronized using intra-vaginal sponges with progesterone and PMSG administration. Results revealed that within CAMAL group, the percentage of animals in heat, onset of oestrus, litter size, birth weight and weaning weight were affected by mating months. September and November were the most appropriate months for oestrus ratio (97.5 % and litter size (1.18 and 0.98, respectively. Lambs of control group were heavier at birth and weaning than those of CAMAL group. On the other hand lamb yield was not affected statistically by the CAMAL administration.

    The aim of this study was to explore the reliability and validity of the Korean version of the Cornell Scale for Depression in Dementia (CSDD-K), a scale for assessment of depression in dementia. The original CSDD was translated into Korean and the content was verified through back-translation procedures. This study included 59 depressive patients with Alzheimer's disease (AD), 62 non-depressive patients with AD and 36 healthy elderly controls. The subjects were assessed using CSDD-K, the 17-item Hamilton Depression Rating Scale (HAM-D(17)), the 15-item Korean version of Geriatric Depression Scale (GDS(15)) and the Korean version of Mini-mental Status Examination (MMSE-K). In the reliability test, Cronbach's α coefficient and test-retest reliabilities were 0.92 and 0.91, respectively, indicating that the CSDD-K has good internal consistency. There were significant differences in CSDD-K total scores between AD patients with depression and AD patients without depression (preliability and validity for the assessment of depressive symptom severity in AD patients. The CSDD-K is a useful instrument for assessing AD patients with depressive symptoms in Korean ethnic population.

    Thermal analysis of the Cornell three-channel silicon crystal is carried out using the ANSYS finite element program. Results are in general agreement with those previously obtained using the Transient Heat Transfer, version B (THTB) program. The main thrust of the present study has been to (a) explore the thermal analysis potentials of the ANSYS program in solving thermal hydraulic problems in the APS beamline design, (b) compare the ANSYS results with those obtained by THTB for a specific test crystal, and (c) obtain some cost benchmarks for the ANSYS program. On the basis of a limited number of test runs for the silicon crystal problem, conclusions can be drawn that (a) except for conduction problems with simple boundary conditions the utility of ANSYS for solving a variety of three-dimensional thermal hydraulic problems is at best limited, (b) in comparison with THTB program, ANSYS requires a more detailed modeling (with increasing computation time) for comparably accurate results, and (c) no firm statement regarding the cost factor can be made at this time although the ANSYS program appears to be more expensive than any other code we have used so far

    Full Text Available A field application of the Cornell Net Carbohydrate and Protein System (CNCPS in Italy has been limited because thefeed bank is based on North American feedstuffs and still few laboratories are able to analyze feeds as requested by theCNCPS. Moreover, the standardization of analytical procedures is still not homogeneous among laboratories. This workwas carried out to establish a first database for feeds commonly used in Italy, providing nutritionists and producers anaccurate and current feed composition, also indicating methods and apparatus for analytical procedures potentially availablefor routine analysis. A total of 909 samples of hays, silages and raw materials (protein feeds, cereals and by-productswere analyzed through 1999 and 2002; analysis included protein solubility and degradability, protein fractions,structural carbohydrate fractions and the calculation of neutral detergent structural carbohydrates. When possible, averagedata were compared with those included in the feed bank of CNCPS ver. 3 and with those obtained by another Italianlaboratory. The main differences were observed in chemical composition of forages and silages, whose composition largelydepends on environmental conditions and physiological stage; protein feeds, cereals and by-products showed somedifferences in crude protein, soluble protein and protein fractions even in feeds of national origin.The intent to modify the feed bank values of CNCPS for establishing an Italian data base of feeds will require a collaborativestudy of many laboratories not only for forages, hays and silages samples - whose composition is greatly dependenton environmental factors and agronomic techniques - but also for protein fractions, whose values are largely influencedby even small changes in analytical techniques.

    Most accounts of the ethical problems facing researchers across a broad spectrum of research fields come from ethicists, ethics committees, and specialists committed to the study of ethics in human research. In contrast, this study reports on the ethical questions that researchers, themselves, report facing in their everyday practice. Fifty-five Swedish researchers contributed 109 examples of ethical dilemmas, conflicts, and problems in research. They were all researchers at the postdoctoral level in the fields of medicine, the humanities, education, and the social sciences, who devoted at least 50 percent of their working hours to research. They reported issues they face before, during, and after gathering data. Their range of issues is broader than generally discussed and points to the importance of researchers' ethical sensitivity.

    Adequate predictions of rumen-degradable protein (RDP) and rumen-undegradable protein (RUP) supplies are necessary to optimize performance while minimizing losses of excess nitrogen (N). The objectives of this study were to evaluate the original Cornell Net Carbohydrate Protein System (CNCPS) protein fractionation scheme and to develop and evaluate alternatives designed to improve its adequacy in predicting RDP and RUP. The CNCPS version 5 fractionates CP into 5 fractions based on solubility in protein precipitant agents, buffers, and detergent solutions: A represents the soluble nonprotein N, B1 is the soluble true protein, B2 represents protein with intermediate rates of degradation, B3 is the CP insoluble in neutral detergent solution but soluble in acid detergent solution, and C is the unavailable N. Model predictions were evaluated with studies that measured N flow data at the omasum. The N fractionation scheme in version 5 of the CNCPS explained 78% of the variation in RDP with a root mean square prediction error (RMSPE) of 275 g/d, and 51% of the RUP variation with RMSPE of 248 g/d. Neutral detergent insoluble CP flows were overpredicted with a mean bias of 128 g/d (40% of the observed mean). The greatest improvements in the accuracy of RDP and RUP predictions were obtained with the following 2 alternative schemes. Alternative 1 used the inhibitory in vitro system to measure the fractional rate of degradation for the insoluble protein fraction in which A = nonprotein N, B1 = true soluble protein, B2 = insoluble protein, C = unavailable protein (RDP: R(2) = 0.84 and RMSPE = 167 g/d; RUP: R(2) = 0.61 and RMSPE = 209 g/d), whereas alternative 2 redefined A and B1 fractions as the non-amino-N and amino-N in the soluble fraction respectively (RDP: R(2) = 0.79 with RMSPE = 195 g/d and RUP: R(2) = 0.54 with RMSPE = 225 g/d). We concluded that implementing alternative 1 or 2 will improve the accuracy of predicting RDP and RUP within the CNCPS framework.

    Full Text Available We present a detailed study of the six-dimensional phase space of the electron beam produced by the Cornell Energy Recovery Linac Photoinjector, a high-brightness, high repetition rate (1.3 GHz DC photoemission source designed to drive a hard x-ray energy recovery linac (ERL. A complete simulation model of the injector has been constructed, verified by measurement, and optimized. Both the horizontal and vertical 2D transverse phase spaces, as well as the time-resolved (sliced horizontal phase space, were simulated and directly measured at the end of the injector for 19 and 77 pC bunches at roughly 8 MeV. These bunch charges were chosen because they correspond to 25 and 100 mA average current if operating at the full 1.3 GHz repetition rate. The resulting 90% normalized transverse emittances for 19   (77  pC/bunch were 0.23±0.02 (0.51±0.04  μm in the horizontal plane, and 0.14±0.01 (0.29±0.02  μm in the vertical plane, respectively. These emittances were measured with a corresponding bunch length of 2.1±0.1 (3.0±0.2  ps, respectively. In each case the rms momentum spread was determined to be on the order of 10^{-3}. Excellent overall agreement between measurement and simulation has been demonstrated. Using the emittances and bunch length measured at 19  pC/bunch, we estimate the electron beam quality in a 1.3 GHz, 5 GeV hard x-ray ERL to be at least a factor of 20 times better than that of existing storage rings when the rms energy spread of each device is considered. These results represent a milestone for the field of high-brightness, high-current photoinjectors.

    2010-12-01

    The Cornell Earth and Environmental Systems (EES) Field Program is a semester-length undergraduate field program located on the island of Hawai`i. The Hawaiian Islands are the world’s most dynamic natural laboratory and the premier location for Earth systems research and education. While there are compelling reasons for students and faculty to travel from the US mainland to Hawai`i, the air and ground travel that comprises the program carries a large carbon footprint. This liability is also an extraordinary educational opportunity. For the past two years EES students have been challenged to make the program carbon-neutral. They are asked to devise a set of criteria for a credible and defensible zero-CO2 footprint and then to put their plan into action. The C-neutral project consists of three elements: (1) quantifying CO2 emissions, (2) reducing emissions wherever possible, and (3) offsetting emissions that cannot be eliminated. In quantifying emissions six areas are identified: air travel, ground travel, domestic electricity, natural gas, food, and waste. Emissions reductions include all of the standard “carpool--turn it down--turn it off “ conservation behaviors, with special emphasis on food and waste; eating local and organic, shopping at re-use centers, and compost and recycling of garbage. Our program facility utilizes solar hot water and is equipped with neither heat nor air conditioning, thus domestic energy use is low. Students tabulate all of our energy use and calculate the resulting CO2 emissions for all program participants for a period of four months. The CO2 offsetting strategy is conducted in collaboration with a native ecosystem restoration project. Students participate in all aspects of forest restoration, including seed collection, germination and outplanting of native plant species and removal of invasive pest species. The initial goal of this locally-supported project was to restore degraded pasture to native forest. The EES students have

    A relatively new technique for measuring the electron cloud density in storage rings has been developed and successfully demonstrated (S. De Santis, J.M. Byrd, F. Caspers, A. Krasnykh, T. Kroyer, M.T.F. Pivi, and K.G. Sonnad, Phys. Rev. Lett. 100, 094801 (2008).). We present the experimental results of a systematic application of this technique at the Cornell Electron Storage Ring Test Accelerator. The technique is based on the phase modulation of the TE mode transmitted in a synchrotron beam pipe caused by the periodic variation of the density of electron plasma. Because of the relatively simple hardware requirements, this method has become increasingly popular and has been since successfully implemented in several machines. While the principles of this technique are straightforward, quantitative derivation of the electron cloud density from the measurement requires consideration of several effects, which we address in detail.

    Cornell University has been designing and building superconducting accelerators for various applications for more than 50 years. Currently, an energy-recovery linac (ERL) based synchrotron-light facility is proposed making use of the existing CESR facility. As part of the phase 1 R and D program funded by the NSF, critical challenges in the design were addressed, one of them being a full linac cryo-module. It houses 6 superconducting cavities- operated at 1.8 K in continuous wave (CW) mode - with individual HOM absorbers and one magnet/ BPM section. Pushing the limits, a high quality factor of the cavities (2⋅10{sup 10}) and high beam currents (100 mA accelerated plus 100 mA decelerated) are targeted. We will present the design of the main linac cryo-module (MLC) being finalized recently, its cryogenic features and report on the status of the fabrication which started in late 2012.

    In 1957, Sandia National Laboratories (Sandia) initiated its first programs in fundamental science, in support of its primary nuclear weapons mission. In 1974, Sandia initiated programs in fundamental science supported by the Department of Energy's Office of Science (DOE-SC). These latter programs have grown to the point where, today in 2011, support of Sandia's programs in fundamental science is dominated by that Office. In comparison with Sandia's programs in technology and mission applications, however, Sandia's programs in fundamental science are small. Hence, Sandia's fundamental science has been strongly influenced by close interactions with technology and mission applications. In many instances, these interactions have been of great mutual benefit, with synergies akin to a positive 'Casimir's spiral' of progress. In this report, we review the history of Sandia's fundamental science programs supported by the Office of Science. We present: (a) a technical and budgetary snapshot of Sandia's current programs supported by the various suboffices within DOE-SC; (b) statistics of highly-cited articles supported by DOE-SC; (c) four case studies (ion-solid interactions, combustion science, compound semiconductors, advanced computing) with an emphasis on mutually beneficial interactions between science, technology, and mission; and (d) appendices with key memos and reminiscences related to fundamental science at Sandia.

    Full Text Available Depression is a major growing public health problem. Many population studies have found a significant relationship between depression and the presence of cognitive disorders. OBJECTIVE: To establish the correlation between the Visual Analogue Scale of Happiness and the Cornell Scale for Depression in Dementia in the population aged 60 years or over in the city of Tremembé, state of São Paulo, Brazil. METHODS: An epidemiological survey involving home visits was carried out in the city of Tremembé. The sample was randomly selected by drawing 20% of the population aged 60 years or older from each of the city's census sectors. In this single-phase study, the assessment included clinical history, physical and neurological examination, cognitive evaluation, and application of both the Cornell Scale and the Analogue Scale of Happiness for psychiatric symptoms. The presence of depressive symptoms was defined as scores greater than or equal to 8 points on the Cornell Scale. RESULTS: A total of 623 subjects were evaluated and of these 251 (40.3% had clinically significant depressive symptoms on the Cornell Scale, with a significant association with female gender (p<0.001 and with lower education (p=0.012. One hundred and thirty-six participants (21.8% chose the unhappiness faces, with a significant association with age (p<0.001, female gender (p=0.020 and low socioeconomic status (p=0.012. Although there was a statistically significant association on the correlation test, the correlation was not high (rho=0.47. CONCLUSION: The prevalence of depressive symptoms was high in this sample and the Visual Analogue Scale of Happiness and Cornell Scale for Depression in Dementia should not be used as similar alternatives for evaluating the presence of depressive symptoms, at least in populations with low educational level.

    We describe a Research Experience for Undergraduates program in astrophysics and planetary science hosted in a major university setting that is geared especially but not exclusively to students who matriculate at smaller colleges and universities without major astronomy research programs, have not previously had off-campus research experiences and/or have non-traditional academic backgrounds.Individual research projects which students undertake with faculty mentors and their research groups are the keystone of the program. Built around this central activity are a set of other components that aim to expose students to the broad areas of astrophysical and planetary science research and to foster their appreciation of the research enterprise and their possible place within it. We describe the professional development activities that are offered to students, including lectures and workshops on a broad range of topics in astrophysics and planetary science, research group meetings, tutorials on research and scientific presentation skills, participation in outreach, education on the graduate school experience and application process, and discussions of the scientific enterprise, career paths and options in astronomy and related fields as well as the role REU group meetings with the program director (which complement meetings students attend within the context of their research group) play in developing students’ scientific competencies and pre-professional development. Also described are program elements that aim to make the program accessible to all students, including older students, those in relationships or with children as well as cohort building. Finally, we discuss lessons learned on how recruiting on merit and suitability to the research projects on offer, with a strong emphasis on smaller colleges and universities without major astronomy research programs can work towards a broader and more inclusive recruitment.This work was supported by NSF award AST-1156780.

    Full Text Available Objective – To better understand the lack of faculty participation in Cornell University’s DSpace institutional repository (IR, and to learn if this lack of participation is peculiar to Cornell or reflective of a larger trend in faculty non-participation in IRs.Design – Comparative analysis and interviews.Setting – Cornell University’s DSpace IR and sciences, social sciences, and humanities faculties; and DSpace installations at 7 other universities.Subjects – The DSpace IR at Cornell University and at 7 other locations. Eleven sciences, social sciences, and humanities faculty members at Cornell University.Methods – The authors analyzed data over a fifteen‐month period from Cornell’s DSpace IR to determine the total deposits, the types of objects deposited, the communities and collections that received deposits, the frequency of deposits, the IP addresses which made deposits, and how often objects in the IR were viewed. These data were compared to equivalent data taken from seven other IRs on all aspects except deposits from IP addresses and how oftenobjects were viewed. Finally, 11 Cornell faculty members from various departments in the sciences, social sciences, and humanities were interviewed over a two month period to provide context to the comparative analysis.Main results – At the time of the study, the IR at Cornell was organized into 193 communities of collections. These collections numbered 196, with 139 of them holding a combined total of 2646 objects: The other 57 collections were empty. While the IR as a whole showed steady growth, 77% of Cornell’s collections reflected a plateau growth pattern of primarily “one time deposits,” approximately 18% exhibited a stair‐step growth pattern of“periodic batch additions of material,” approximately 3% showed steady growth, and 1.4% were “uncatagorizable.” Five hundred nineteen unique IP addresses made deposits to Cornell’s IR over the course of the fifteen

    Electron cloud related emittance dilution and instabilities of bunch trains limit the performance of high intensity circular colliders. One of the key goals of the Cornell electron-positron storage ring Test Accelerator (CesrTA) research program is to improve our understanding of how the electron cloud alters the dynamics of bunches within the train. Single bunch beam diagnotics have been developed to measure the beam spectra, vertical beam size, two important dynamical effects of beams interacting with the electron cloud, for bunch trains on a turn-by-turn basis. Experiments have been performed at CesrTA to probe the interaction of the electron cloud with stored positron bunch trains. The purpose of these experiments was to characterize the dependence of beam-electron cloud interactions on the machine parameters such as bunch spacing, vertical chromaticity, and bunch current. The beam dynamics of the stored beam, in the presence of the electron cloud, was quantified using: 1) a gated beam position monitor (BPM) and spectrum analyzer to measure the bunch-by-bunch frequency spectrum of the bunch trains; 2) an x-ray beam size monitor to record the bunch-by-bunch, turn-by-turn vertical size of each bunch within the trains. In this paper we report on the observations from these experiments and analyze the effects of the electron cloud on the stability of bunches in a train under many different operational conditions

    To examine the clinical utility of the Cornell Scale for Depression in Dementia (CSDD) in nursing homes. 14 nursing homes in Sydney and Brisbane, Australia. 92 residents with a mean age of 85 years. Consenting residents were assessed by care staff for depression using the CSDD as part of their routine assessment. Specialist clinicians conducted assessment of depression using the Semi-structured Clinical Diagnostic Interview for DSM-IV-TR Axis I Disorders for residents without dementia or the Provisional Diagnostic Criteria for Depression in Alzheimer Disease for residents with dementia to establish expert clinical diagnoses of depression. The diagnostic performance of the staff completed CSDD was analyzed against expert diagnosis using receiver operating characteristic (ROC) curves. The CSDD showed low diagnostic accuracy, with areas under the ROC curve being 0.69, 0.68 and 0.70 for the total sample, residents with dementia and residents without dementia, respectively. At the standard CSDD cutoff score, the sensitivity and specificity were 71% and 59% for the total sample, 69% and 57% for residents with dementia, and 75% and 61% for residents without dementia. The Youden index (for optimizing cut-points) suggested different depression cutoff scores for residents with and without dementia. When administered by nursing home staff the clinical utility of the CSDD is highly questionable in identifying depression. The complexity of the scale, the time required for collecting relevant information, and staff skills and knowledge of assessing depression in older people must be considered when using the CSDD in nursing homes.

    There are few studies on validation of depression scales in the elderly in Latin America. This study aimed to assess the validity of Montgomery-Åsberg. Depression Rating Scale (MADRS) and Cornell Scale for Depression in Dementia (CSDD) in Brazilian elderly outpatients. A convenience sample of 95 outpatients was diagnosed for dementia and depression according to DSM-IV-TR, ICD-10, and PDC-dAD criteria. Receiver Operating Curves (ROC) were used to calculate the area under the curve (AUC) and to assess MADRS and CSDD cut-offs for each diagnostic criterion. Dementia was diagnosed in 71 of 95 patients. Depression was diagnosed in 35, 30, and 51 patients by ICD-10, DSM-IV, and PDC-dAD, respectively. MADRS cut-off score of 10 correctly diagnosed 67.4% and 66.3% patients as depressed according to DSM-IV and ICD-10. A cut-off of 9 correctly identified 74.7% by PDC-dAD criteria; a CSDD cut-off score of 13 best recognized depression according to DSM-IV and ICD-10. A score of 11 diagnosed depression according to PDC-dAD, while MADRS = 9 recognized depression in dementia. CSDD was more efficient in showing depression in mild than in moderate/severe dementia according to DSM-IV/ICD-10. PDC-dAD behaved nicely for any severity stage. MADRS and CSDD cut-offs of 10 and 13 were the optimal ones to diagnose depression in elderly, respectively. CSDD cut-offs are higher than those found in other countries. Other Latin American studies are needed to compare results with our study.

    2014-09-01

    Student perceptions of school climate represent the ways students feel about the school environment. These include perceptions regarding safety, teaching and learning, and relationships within the school. It has been found that student perceptions of school climate are positively correlated with academic achievement (Brookover et al., 1978), and negatively correlated with risky behaviors (Bandyopadhyay, Cornell, & Konold, 2009; Bayar & Ucanok, 2012; Wang, Berry, & Swearer, 2013). The Georgia Brief School Climate Inventory (GaBSCI) is a measure of student perceptions of school climate. The brevity of the 9-item instrument makes it ideal as a general measure that can be used to monitor student perceptions of school climate. The survey was anonymously administered to 130,968 sixth- and eighth-grade students in the state of Georgia. Cronbach's alpha for the scale was 0.71. Exploratory and confirmatory factor analyses verified the scale's structure. Student perceptions of climate from the GaBSCI varied based on race/ethnicity, gender, and grade. Additional support for the construct validity of the GaBSCI was obtained based on its relationships with several behaviors related to bullying, and the moderating effects of grade and gender on these relationships. Implications for research and practice are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    2013-01-01

    My Brief History recounts Stephen Hawking’s improbable journey, from his postwar London boyhood to his years of international acclaim and celebrity. Lavishly illustrated with rarely seen photographs, this concise, witty, and candid account introduces readers to a Hawking rarely glimpsed in previous books: the inquisitive schoolboy whose classmates nicknamed him Einstein; the jokester who once placed a bet with a colleague over the existence of a particular black hole; and the young husband and father struggling to gain a foothold in the world of physics and cosmology. Writing with characteristic humility and humor, Hawking opens up about the challenges that confronted him following his diagnosis of ALS at age twenty-one. Tracing his development as a thinker, he explains how the prospect of an early death urged him onward through numerous intellectual breakthroughs, and talks about the genesis of his masterpiece A Brief History of Time—one of the iconic books of the twentieth century.

    We use the CLEO detector at the Cornell e + e - storage ring, CESR, to search for the two-photon production of the glueball candidate f J (2220) in its decay to K s K s . We present a restrictive upper limit on the product of the two-photon partial width and the K s K s branching fraction, (Γ γγ B K s K s ) f J(2220) . We use this limit to calculate a lower limit on the stickiness, which is a measure of the two-gluon coupling relative to the two-photon coupling. This limit on stickiness indicates that the f J (2220) has substantial glueball content. copyright 1997 The American Physical Society

    Taxometric procedures provide an empirical means of determining which psychiatric disorders are typologically distinct from normal behavioral functioning. Although most disorders reflect extremes along continuously distributed behavioral traits, identifying those that are discrete has important implications for accurate diagnosis, effective treatment, early identification of risk, and improved understanding of etiology. This article provides (a) brief descriptions of the conceptual bases of several taxometric procedures, (b) example analyses using simulated data, and (c) strategies for avoiding common pitfalls that are often observed in taxometrics research. To date, most taxometrics studies have appeared in the adult psychopathology literature.

    The stunning, intricate interaction between the visual, vestibular and optomotor systems--each a miracle on its own--ensures maintenance of orientation in space as well as visual recognition and target selection despite a host of sensory conflicts and adversary disturbances. Their main goals are to keep a target of interest on the fovea by either maintaining or shifting the direction of gaze in order to produce an accurate internal representation of the visual surroundings, in particular the selected target, and to continuously mirror the spatial relationship between these various visual elements and the self. Not surprising, the implementation of this host of elaborate neural networks encompasses almost every part of the brain, including the brainstem, cerebellum, extrapyramidal system and many areas of the cerebral cortex. Thus far, these systems are among the best investigated in brain research; and enormous knowledge was amassed over the last century employing a variety of techniques, including single cell recordings, eye movement studies, functional imaging and neuropsychological observations. In addition, this prolific line of research has enlightened many fundamental principles of neural and neuronal processing, which have subsequently enriched other fields of brain research as well as computational neuroscience, e.g. the discovery of receptive fields, which have now become a ubiquitous concept in many other areas of neurophysiology. This (improperly) brief, fractional and undoubtedly biased Vademecum is meant to accompany the reader into this marvellous field of neurophysiology and neurology. In particular, it stresses the clinical application of its functional neuroanatomy at the bedside, which, in many respects, is superior to other means of investigating a patient

    The authors describe the factors that led Weill Cornell Medical College in Qatar (WCMC-Q) to establish the Center for Cultural Competence in Health Care from the ground up, and they explore challenges and successes in implementing cultural competence training.Qatar's capital, Doha, is an extremely high-density multicultural setting. When WCMC-Q's first class of medical students began their clinical clerkships at the affiliated teaching hospital Hamad Medical Corporation in 2006, the complicated nature of training in a multicultural and multilingual setting became apparent immediately. In response, initiatives to improve students' cultural competence were undertaken. Initiatives included launching a medical interpretation program in 2007; surveying the patients' spoken languages, examining the effect of an orientation program on interpretation requests, and surveying faculty using the Tool for Assessing Cultural Competence Training in 2008; implementing cultural competence training for students and securing research funding in 2009; and expanding awareness to the Qatar community in 2010. These types of initiatives, which are generally highly valued in U.S. and Canadian settings, are also apropos in the Arabian Gulf region.The authors report on their initial efforts, which can serve as a resource for other programs in the Arabian Gulf region.

  15. Electricity Storage. Technology Brief

    Electricity storage is a key technology for electricity systems with a high share of renewables as it allows electricity to be generated when renewable sources (i.e. wind, sunlight) are available and to be consumed on demand. It is expected that the increasing price of fossil fuels and peak-load electricity and the growing share of renewables will result in electricity storage to grow rapidly and become more cost effective. However, electricity storage is technically challenging because electricity can only be stored after conversion into other forms of energy, and this involves expensive equipment and energy losses. At present, the only commercial storage option is pumped hydro power where surplus electricity (e.g. electricity produced overnight by base-load coal or nuclear power) is used to pump water from a lower to an upper reservoir. The stored energy is then used to produce hydropower during daily high-demand periods. Pumped hydro plants are large-scale storage systems with a typical efficiency between 70% and 80%, which means that a quarter of the energy is lost in the process. Other storage technologies with different characteristics (i.e. storage process and capacity, conversion back to electricity and response to power demand, energy losses and costs) are currently in demonstration or pre-commercial stages and discussed in this brief report: Compressed air energy storage (CAES) systems, Flywheels; Electrical batteries; Supercapacitors; Superconducting magnetic storage; and Thermal energy storage. No single electricity storage technology scores high in all dimensions. The technology of choice often depends on the size of the system, the specific service, the electricity sources and the marginal cost of peak electricity. Pumped hydro currently accounts for 95% of the global storage capacity and still offers a considerable expansion potential but does not suit residential or small-size applications. CAES expansion is limited due to the lack of suitable

    Integrated assessment can be used to evaluate and clarify resource management policy options and outcomes for decision makers. The defining characteristics of integrated assessment are (1) focus on providing information and analysis that can be understood and used by decision makers rather than for merely advancing understanding and (2) its multidisciplinary approach, using methods, styles of study, and considerations from a broader variety of technical areas than would typically characterize studies produced from a single disciplinary standpoint. Integrated assessment may combine scientific, social, economic, health, and environmental data and models. Integrated assessment requires bridging the gap between science and policy considerations. Because not everything can be valued using a single metric, such as a dollar value, the integrated assessment process also involves evaluating trade-offs among dissimilar attributes. Scientists at Oak Ridge National Laboratory (ORNL) recognized the importance and value of multidisciplinary approaches to solving environmental problems early on and have pioneered the development of tools and methods for integrated assessment over the past three decades. Major examples of ORNL`s experience in the development of its capabilities for integrated assessment are given.

    Full Text Available American theories of reincarnation have a long and complex history, dating from 1680s to the present. It is the purpose of this paper to highlight the main currents of reincarnation theory in the American context, giving a brief historical survey. Sources surveyed begin with Native American traditions, and then move to immigrant traditions based in Western Esotericism, Christianity, Judaism, missionary Hinduism and Buddhism, Spiritualism, Theosophy, Rosicrucianism, and concludes with more current theoretical influences, based in paranormal science research. The paper demonstrates that current theories of reincarnation are increasingly less dependent upon religious support and increasingly based in direct personal experience, paranormal research, and new therapeutic models. The paper concludes with some reflections on the complexity of reincarnation theory and raises questions concerning the future development of such theory.

A series of cross-sectional studies were conducted involving: 1) descriptive analysis of pooled data from five nursing home studies that used the CSDD-19 (N = 671) to identify patterns of responses and missing data on individual CSDD items; 2) analysis of four of the five studies (N = 556) to assess CSDD-19 for unidimensionality, item fit, and differential item functioning using Rasch modeling to develop a shorter version, the CSDD-4; 3) validation of the CSDD-4 against the DSM-IV using the fifth study of 115 residents and through expert consultations; and 4) evaluation of the clinical utility of CSDD-4 using an independent cohort of 92 nursing home residents. Four items from the original CSDD-19 were found to be most suitable for depression screening: anxiety, sadness, lack of reactivity to pleasant events, and irritability. The CSDD-4 highly correlated with the original scale (N = 474, r = 0.831, p dementia. The CSDD-4 had an area under the curve (AUC) of 0.73 (z = 3.47, p depression in nursing homes. Its adoption is feasible and practical for nursing home staff, and may facilitate more comprehensive assessment and management of depression in nursing home residents.

    Full Text Available Dairy cows often do not receive adequate nutrient supply during their lactation period. This condition caneven be worse if the environmental temperature is not in comfortable range which may occur especially intropical regions. The present research was aimed to simulate the effect of supplementary feeding on nutrientbalance of lactating dairy cow at contrasting temperature regimes using Cornell Net Carbohydrate andProtein System (CNCPS model. Treatments consisted of feeds (R1: Pennisetum purpureum, R2: P.purpureum + concentrate (60:40, R3: P. purpureum + Gliricidia sepium + Leucaena leucocephala(60:20:20, R4: P. purpureum + concentrate + G. sepium + L. leucocephala (60:20:10:10 and environmentaltemperatures (T1: 20 oC, T2: 30 oC. The dairy cow inputs in CNCPS were Holstein breed, body weight of500 kg, feed intake of 15 kg (dry matter basis per day and produced milk 15 kg/day. Based on the CNCPSmodel, there were negative balances of metabolisable energy (ME and metabolisable protein (MP if alactating dairy cow fed only by P. purpureum. The ME balance was worse at higher temperature, while theMP balance was remain unchanged. Addition of concentrate mixture (R2 fulfilled the ME and MPrequirements as well as other nutrients. Addition of leguminous tree leaves (R3 and R4 improved thenutritional status of the lactating cow model compared to R1, but did not better than R2. It was concludedthat supplementary feeding is necessary for improving the nutrient balance of lactating dairy cow, especiallywhen the cow is maintained under uncomfortable environmental temperature.

The sample included 128 prostate cancer patients recruited from urology and general oncology clinics at two Chicago-area hospitals. The main outcome measures were: A 36-item PF item bank that included a 5-item short form (BriefPF and the 10-item PF subscale (PF-10 from the Medical Outcomes Study SF-36. Validity, information function, and relative precision (calculated using Rasch analysis and raw scores of the BriefPF were compared to the PF-10 and the full PF item bank. We found that the BriefPF and PF-10 were strongly correlated (r = 0.85 with the PF bank, and all three scales differentiated patients according to performance status (FPF bank(2,124 = 32.51 P < 0.001, FPF-10(2,121 = 27.35 P < 0.001, FBriefPF (2,123 = 38.40 P < 0.001. BriefPF has excellent precision relative to the PF-10 in measuring patients with different performance status levels. The Rasch-based information function indicated that the BriefPF was more informative than PF-10 in measuring moderate to higher functioning patients. Hence, the BriefPF offers a parsimonious and precise measure of PF for use among men with prostate cancer, and may aid in the timely inclusion of patient-reported outcomes in treatment decision-making.Keywords: quality-of-life, item bank, short-form, Medical Outcomes Study

However, the lack of appropriate characterization of the feeds has restricted its application. The objective of this study was to develop and evaluate a feed library containing feeds commonly used in tropical regions with characteristics needed as inputs for the CNCPS. Feed composition data collected from laboratory databases and from experiments published in scientific journals were used to develop this tropical feed library. The total digestible nutrients (TDN predicted at 1x intake of maintenance requirement with the CNCPS model agreed with those predicted by the Weiss et al. (1992 equation (r² of 92.7%, MSE of 13, and bias of 0.8% over all feeds. However, the regression r² of the tabular TDN values and the TDN predicted by the CNCPS model or with the Weiss equation were much lower (58.1 and 67.5%, respectively. A thorough comparison between observed and predicted TDN was not possible because of insufficient data to characterize the feeds as required by our models. When we used the mean chemical composition values from the literature data, the TDN predicted by our models did not agree with the measured values. We conclude using the TDN values calculated using the Weiss equation and the CNCPS model that are based on the actual chemical composition of the feeds result in energy values that more accurately represent the feeds being used in specific production situations than do the tabular values. Few papers published in Latin America journals that were used in this study reported information need by models such as the CNCPS.O uso do Sistema de Carboidrato e Proteina Líquidos da Universidade de Cornell (CNCPS tanto para produção de leite como carne tem aumentado durante o últimos anos nas regiões tropicais.

    Real innovations in medicine and science are historic and singular; the stories behind each occurrence are precious. At Molecular Medicine we have established the Anthony Cerami Award in Translational Medicine to document and preserve these histories. The monographs recount the seminal events as told in the voice of the original investigators who provided the crucial early insight. These essays capture the essence of discovery, chronicling the birth of ideas that created new fields of research; and launched trajectories that persisted and ultimately influenced how disease is prevented, diagnosed, and treated. In this volume, the first Cerami Award Monograph, by Carl Nathan, MD, chairman of the Department of Microbiology and Immunology at Weill Cornell Medical College, reflects towering genius and soaring inspiration.

    Preoperative briefings have been proven beneficial for improving team performance in the operating room. However, there has been minimal research regarding team briefings in specific surgical domains. As part of a larger project to develop a briefing structure for gynecological surgery, the study aimed to better understand the current state of pre-operative team briefings in one department of an academic hospital. Twenty-four team briefings were observed and video recorded. Communication was analyzed and social network metrics were created based on the team member verbal interactions. Introductions occurred in only 25% of the briefings. Network analysis revealed that average team briefings exhibited a hierarchical structure of communication, with the surgeon speaking the most frequently. The average network for resident-led briefings displayed a non-hierarchical structure with all team members communicating with the resident. Briefings conducted without a standardized protocol can produce variable communication between the role leading and the team members present. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available The following text contains a brief journey through a short and yet intense adventure, the history of videogames. Since its beginnings in the 1950's decade to the present time, videogames have progressively changed from a hobby for ingeneering studens to the most powerfull leisure industry. In order to gain a better understanding of this phenomenon it is necessary to look over the path of its transformation from a retrospecive point of view. Such a look has necessarily to focus on those devices and games that had made a landmark in the history of videogames, taking them to their current position. Besides, it is crucial to address their implications in contemporary visual culture, along with current prejudices against them. This is a short account about a great history.

    Full Text Available Breast infections commonly affect women aged between 18 and 50 years and are categorized as lactational and non-lactational infections. The infection can affect the skin overlying the breast when it can be a primary event or, it may occur secondary to mastitis and/or, secondary to a lesion in the skin. The commoner clinical findings consist of a tender, hard breast mass with erythema of the overlying skin. Needle aspiration yields pus cultures of which yield the infecting microorganisms. In practice, treatment is usually empiric consisting of bed rest, frequent nursing, fluids, Acetaminophen for pain and fever and a course of antibiotics. The other common line of treatment for breast abscess consists of incision and drainage with primary and/or, secondary closure. This brief communication on breast abscess gives an overview of the possible etiologies, clinical signs and symptoms and the treatment lines for breast abscess.

    2018-02-01

    The theory of probability has been debated for centuries: back in 1600, French mathematics used the rules of probability to place and win bets. Subsequently, the knowledge of probability has significantly evolved and is now an essential tool for statistics. In this paper, the basic theoretical principles of probability will be reviewed, with the aim of facilitating the comprehension of statistical inference. After a brief general introduction on probability, we will review the concept of the "probability distribution" that is a function providing the probabilities of occurrence of different possible outcomes of a categorical or continuous variable. Specific attention will be focused on normal distribution that is the most relevant distribution applied to statistical analysis.

  14. A brief history of CERN

    International Nuclear Information System (INIS)

    Jacob, M.

    2004-01-01

    This article draws a brief history of CERN that has just celebrated its jubilee. Today 20 member states contribute to its annual budget that reached 650 million euros in 2004. In 1954 CERN was created by 12 founder states for mainly 3 reasons: 1) to achieve a research facility dedicated to particle physics able to compete with its American counterparts and that no European country could afford alone, 2) to generate with scientific research an example and a promoter for future international collaborations, and 3) to make scientists from different countries that were at war a few years before, to work together. The creation of CERN has not led to a decline of national laboratories as it was feared in the fifties. On the contrary scientific and technical tasks have been dispatched: CERN provides member states with accelerator facilities while national laboratories and universities contribute to the design and fabrication of detectors and to the analysis of experimental data. The history of CERN is marked by 2 main scientific milestones, first the discovery of weak interaction through neutral currents in 1973 and secondly the discovery of W and Z bosons in 1983. (A.C.)

    2018-01-01

    The history of Shigella , the causative agent of bacillary dysentery, is a long and fascinating one. This brief historical account starts with descriptions of the disease and its impact on human health from ancient time to the present. Our story of the bacterium starts just before the identification of the dysentery bacillus by Kiyoshi Shiga in 1898 and follows the scientific discoveries and principal scientists who contributed to the elucidation of Shigella pathogenesis in the first 100 years. Over the past century, Shigella has proved to be an outstanding model of an invasive bacterial pathogen and has served as a paradigm for the study of other bacterial pathogens. In addition to invasion of epithelial cells, some of those shared virulence traits include toxin production, multiple-antibiotic resistance, virulence genes encoded on plasmids and bacteriophages, global regulation of virulence genes, pathogenicity islands, intracellular motility, remodeling of host cytoskeleton, inflammation/polymorphonuclear leukocyte signaling, apoptosis induction/inhibition, and "black holes" and antivirulence genes. While there is still much to learn from studying Shigella pathogenesis, what we have learned so far has also contributed greatly to our broader understanding of bacterial pathogenesis.

  16. Brief review of neutrino physics

    International Nuclear Information System (INIS)

    Sciulli, F.

    1986-01-01

    This paper provides a brief review of neutrino physics. The running of the coupling constant, α/sub s/, predicted by QCD is not seen presently by using measurements of R/sub hadron/. However, the systematic errors on the measurements still allow a running α/sub s/. It should be noted that when calculating α/sub s/ at the J/psi and Υ using the technique of a previous work, a running α/sub s/ is also not observed, but is allowed within error. Evidence for the three gluon coupling predicted by QCD is still lacking. The search for gluonic mesons has continued to be inconclusive, even though candidate meson properties have been considerably refined. Searches for right-handed currents have so far proved negative, though impressive mass limits have been obtained. Searches for supersymmetric particles have also proved negative, with mass limits strongly coupled to accelerator energy. Much enthusiasm and inventiveness has been generated by the announcement of two possible new states, ξ and zeta however, the existence of these states is presently uncertain. In the case of the zeta, theoretical interpretation outside the S-M played a very prominent role

  17. Brief concept of hip preservation

    2017-12-01

    Full Text Available Restoration of the anatomy of the hip joint and biomechanics across it, carry the immense importance to prevent future osteoarthritis of the joint. The aim of this review is to provide the brief concept of the methods to preserve the hip, especially in young adults. Attempts to preserve the hips start with the intense preoperative planning of the corrective procedure. Different parameters regarding the femur and acetabulum in all 3 dimensions need to be assessed. Especially, measurement of the anteversion of the femur and acetabulum is a significant step to avoid osteoarthritis. In addition, the suprapelvic and infrapelvic (spine and lower limb lengths alignment needs to be considered in the planning. Correction of the femoral side of the hip needs the understanding of the blood supply of the proximal femur which carries the risk of avascular necrosis more so with intracapsular osteotomies. Acetabular reorientation, to re-distribute the forces over the weight bearing part, can be carried out with re-directional osteotomy such as periacetabular osteotomy. It needs the understanding of the acetabular anatomy and the force distribution in it. To conclude, correction of both femoral and acetabular side parameters need to be considered in decision making depending on the alterations due to various etiologies causing the hip disorders.

    1998-04-01

    After its launch on 2 December 1995, SOHO travelled to take up a special orbit 1.5 million kilometres away on the sunward side of the Earth, where the Sun never sets. The full scientific programme began in April 1996. The occasion for the briefing is the celebration of that second anniversary and of the mission's extension to 2003. Organized by the European Space Agency, the briefing will be hosted by the Rutherford Appleton Laboratory, which is near Oxford. Leading scientists associated with SOHO will announce to the press some remarkable new discoveries about the Sun's interior, atmosphere and solar wind. They will also briefly review the main achievements of the past two years. The role of SOHO as the chief watchdog for storms on the Sun that may affect the Earth will be demonstrated. Europe's creation of the finest spacecraft ever built to observe the Sun will be recalled by a top engineer from ESA. A speaker from NASA will explain transatlantic contributions to SOHO, which is a project of international cooperation between ESA and NASA. ESA's director of science will also be present, to relate SOHO to ESA's general science programme. A lunch-time talk by the BNSC's director of science completes the line-up of speakers. This is also an exceptional opportunity for the press to meet and interview scientists from all over Europe and the USA, who are attending a meeting at the Rutherford Appleton Laboratory of SOHO's Science Working Team (SWT). Journalists are usually excluded from such meetings. The Rutherford Appleton Laboratory plays a prominent part in SOHO, particularly through its provision of the CDS ultraviolet spectrometer. A visit to the CDS group will provide a chance to see what space research is really like. Please indicate your intention to attend, on the accreditation form that follows the schedule.

Fracionamento dos carboidratos pelas equações do Cornell Net Carbohydrate and Protein System de três cultivares de girassol na presença ou não de irrigação Carbohydrate fractionation of three sunflower cultivars in the presence or absence of irrigation using the Cornell Net Carbohydrate and Protein System equations

    Full Text Available Objetivou-se quantificar as frações de carboidratos pelas equações do Cornell Net Carbohydrate and Protein System (CNCPS de três cultivares de girassol (Helianthus annuus L. cultivados na presença ou não de irrigação. A utilização de uma preparação fibrosa, denominada parede celular (PC, nas equações da CNCPS, em substituição à fibra em detergente neutro (FDN não promoveu diferenças nas frações de carboidratos B1 e C, mas influenciou as frações A e B2. Como os valores da fração B1, obtidos pelo modelo CNCPS foram menores que os teores de amido e pectina determinados em laboratório, supõe-se que a pectina e outros oligossacarídeos da parede celular, solubilizados pela solução de detergente neutro (fibra solúvel, nunca fizeram parte da fração B1, e sim da fração A. Apesar de os carboidratos da fibra solúvel apresentarem elevadas taxas de degradação, não parece adequada a caracterização da fibra solúvel na fração A. Parece mais adequado que a fibra solúvel (que inclui a pectina seja alocada a uma fração exclusivamente sua, que pode ser a fração B2, e que seja criada uma nova fração, a B3, para os carboidratos digeríveis da parede celular. Assim, a fração B1 seria composta apenas de amido. A equação da fração C, que estima os carboidratos indigeríveis da parede celular, pode ser simplificada, relacionando a fração indigerível ao teor de lignina na matéria seca, e não à FDN isenta de cinzas e proteína, como atualmente utilizado. Esta proposta tem implicações práticas, uma vez que a fração indigerível da parede celular tem sido expressa em relação à FDN, e não na MS, com base no fato de que os efeitos inibitórios da lignina ocorrem sobre os componentes fibrosos da parede celular vegetal, e não sobre o conteúdo celular.This work aimed to estimate the carbohydrate fractions in three sunflower (Helianthus annuus L. cultivars in the presence or absence of irrigation, using the

    Apart from the journals they produce, scientific societies play an important role in communicating scientific findings and norms to the broader society. The American Association for the Advancement of Science (AAAS) includes among its goals to promote and defend the integrity of science and its use; provide a voice for science on societal issues; promote the responsible use of science in public policy; and increase public engagement with science and technology. AAAS websites and programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (http://www.aaas.org/spp/cstc/wwc/book.htm) and ScienceCareers.org (http://sciencecareers.sciencemag.org), provide tools for scientists to become more directly engaged in effectively communicating their findings and involved in the policy process. Education programs work to build the next generation of scientists and a science-literate public. To bridge the current communication gap between scientists, the public and policymakers, AAAS, like other scientific societies, maintains policy and outreach programs with limited budgets and staff. AAAS works to engage policymakers and provide scientific underpinning to key issues through congressional briefings, meetings, policy briefs, and media outreach. AAAS responds to challenges to accepted scientific findings and processes through op-eds, letters to government officials, resolutions, and Board statements. Some of these initiatives occur on a local level in partnership with local civic leaders, whose endorsement makes them more powerful. On a national scale, they assure that the voice of science is included in the debate. The changing media landscape presents opportunities and challenges for future AAAS endeavors.

    Scientists and engineers in all disciplines are required to communicate with colleagues, the media, policy-makers, and/or the general public. However, most STEM graduate programs do not equip students with the skills needed to communicate effectively to these diverse audiences. In this presentation, we describe a science communication course developed by and for graduate students at Cornell University. This training, which has been implemented as a semester-long seminar and a weekend-long workshop, covers popular science writing, science policy, print and web media, radio and television. Here we present a comparison of learning outcomes for the semester and weekend formats, a summary of lessons learned, and tools for developing similar science communication programs for graduate students at other institutions.

    2011-01-01

    This brief commentary will argue that whether hormesis is considered in regulatory risk assessment is a matter less of science than of science policy. I will first discuss the distinction between science and science policy and their roles in regulatory risk assessment. Then I will focus on factors that influence science policy, especially as it relates to the conduct of risk assessments to inform regulatory decisions, with a focus on the U.S. Environmental Protection Agency (EPA). The key questions will then be how does hormesis interact with current concepts of science and science policy for risk assessment? Finally, I look ahead to factors that may increase, or decrease, the likelihood of hormesis being incorporated into regulatory risk assessment.

  16. Cold fusion saga: Lesson in science

    Lewenstein, B.V.

    1992-01-01

    A news conference at the University of Utah on March 23, 1989, ignited an explosion of scientific tempers almost as intense as the topic up for discussion - nuclear fusion. Two electrochemists, B. Stanley Pons and Martin Fleischmann, announced they had discovered a method for creating nuclear fusion at room temperature, using simple equipment available in any high school laboratory. This could mean unlimited supplies of cheap electricity in the future. The announcement set off a chain reaction involving the news media and scientists worldwide, notes Bruce V. Lewenstein of Cornell University. For the first six weeks of the saga, Lewenstein recalls, competing claims, counterclaims, and interpretations led to what many headline writers referred to as fusion confusion. Media attention faded gradually, but scientific attention didn't. Over the next two years, laboratory experiments, scientific reports, meetings, and panels kept the issue boiling. The cold-fusion saga, while more intense than some scientific research, followed familiar paths, Lewenstein believes. News coverage, political maneuvering, competition among scientists, parent rights, arguments about the interpretation of experiments - all points of contention - are normal, indeed, one might almost say integral, to modern science, he says. This is the stuff science is made of, he adds. And for those disturbed by the implications, Lewenstein cautions that cold-fusion may be the harbinger for other high-profile science, such as high-temperature superconductors

  17. NEWS: Why choose science?

    National concerns over the uptake of science subjects and an analysis of how school science departments together with careers programmes influence students' subject choices feature in a recent report from the UK's National Institute for Careers Education and Counselling. It points out that decisions on science subjects are taken very early in pupils' education, often well before the implications of those choices can be clearly understood. If pupils are to be encouraged to keep science options open, then both science teachers and careers advisers have important roles to play. Physics is in fact singled out in the report's recommendations as in need of special attention, due to its perceived difficulty both within the double-award science course and also at A-level. The lack of qualified teachers in physics is noted as a problem for schools and the many initiatives to address these issues should be encouraged according to the report, but within an overall high-profile and well funded national strategy for developing science education in schools. The report also notes that science teachers do not feel able to keep up with career information, whilst few careers advisers have a science background and have little opportunity to build up their knowledge of science syllabuses or of science and engineering careers. More contact between both types of specialist is naturally advocated. Copies of the full report, Choosing Science at 16 by Mary Munro and David Elsom, are available from NICEC, Sheraton House, Castle Park, Cambridge CB3 0AX on receipt of an A4 stamped (70p) addressed envelope. A NICEC briefing summary is also available from the same address (20p stamp required).

    The usual science course is not meant to be a history course and the usual science book is not meant to be a history book. However, most science books do include some historical information. Unfortunately, the history part is usually so brief that it is far from interesting and often so oversimplified that it is totally wrong. Introductory physics…

    2018-05-01

    While most of Radon transform applications to imaging involve integrations over smooth sub-manifolds of the ambient space, lately important situations have appeared where the integration surfaces are conical. Three of such applications are single scatter optical tomography, Compton camera medical imaging, and homeland security. In spite of the similar surfaces of integration, the data and the inverse problems associated with these modalities differ significantly. In this article, we present a brief overview of the mathematics arising in Compton camera imaging. In particular, the emphasis is made on the overdetermined data and flexible geometry of the detectors. For the detailed results, as well as other approaches (e.g. smaller-dimensional data or restricted geometry of detectors) the reader is directed to the relevant publications. Only a brief description and some references are provided for the single scatter optical tomography. This work was supported in part by NSF DMS grants 1211463 (the first two authors), 1211521 and 141877 (the third author), as well as a College of Science of Texas A&M University grant.

  7. Constructivism in Science and Science Education: A Philosophical Critique

    Science.gov (United States)

    Nola, Robert

    This paper argues that constructivist science education works with an unsatisfactory account of knowledge which affects both its account of the nature of science and of science education. The paper begins with a brief survey of realism and anti-realism in science and the varieties of constructivism that can be found. In the second section the important conception of knowledge and teaching that Plato develops in the Meno is contrasted with constructivism. The section ends with an account of the contribution that Vico (as understood by constructivists), Kant and Piaget have made to constructivist doctrines. Section three is devoted to a critique of the theory of knowledge and the anti-realism of von Glaserfeld. The final section considers the connection, or lack of it, between the constructivist view of science and knowledge and the teaching of science.

  8. Epidemiological methods: a brief review

    Winkelstein, W. Jr.

    1983-01-01

    Epidemiology, the study of disease distributions in populations and the factors which influence these distributions, is an observational science, i.e., its data base consists of measurements made on free living individuals characterized by presence or absence of disease states and putative risk factors. Epidemiological studies are usually classified as descriptive or analytical. Descriptive studies are primarily used for planning and evaluating health programs or to generate etiological hypotheses. Analytical studies are primarily used for testing etiological hypotheses. Analytical studies are designed either as cohort investigations in which populations with and without a putative risk factor are followed through time to ascertain their differential incidence of disease, or case-control investigations in which the history of exposure to a putative risk factor is compared among persons with a disease and appropriate controls free of disease. Both descriptive and analytical epidemiological studies have been applied to health physics problems. Examples of such problems and the epidemiological methods used to explore them will be presented

    1996-09-01

    If students of science are to have more career options in the future, the people who hire and work with them are going to have to know more science and more about what scientists do. That's one of the conclusions of a recent study of the perceptions and realities that young and mid-career physical scientists are having to cope with in a post-cold war environment. It's also the conclusion of a survey of CEO's from 500 of the Fortune 1000 companies in the U.S, undertaken in September and October 1995 by the Johnson School of Management at Cornell. Corporations are becoming more and more concerned about "science and technological illiteracy" on the part of their managers.

  13. A History of Soil Science Education in the United States

    Science.gov (United States)

    Brevik, Eric C.

    2017-04-01

    The formal study of soil science is a fairly recent undertaking in academics. Fields like biology, chemistry, and physics date back hundreds of years, but the scientific study of soils only dates to the late 1800s. Academic programs to train students in soil science are even more recent, with the first such programs only developing in the USA in the early 1900s. Some of the first schools to offer soil science training at the university level included the University of North Carolina (UNC), Earlham College (EC), and Cornell University. The first modern soil science textbook published in the United States was "Soils, Their Properties and Management" by Littleton Lyon, Elmer Fippin and Harry Buckman in 1909. This has evolved over time into the popular modern textbook "The Nature and Properties of Soils", most recently authored by Raymond Weil and Nyle Brady. Over time soil science education moved away from liberal arts schools such as UNC and EC and became associated primarily with land grant universities in their colleges of agriculture. There are currently about 71 colleges and universities in the USA that offer bachelors level soil science degree programs, with 54 of these (76%) being land grant schools. In the 1990s through the early 2000s enrollment in USA soil science programs was on the decline, even as overall enrollment at USA colleges and universities increased. This caused considerable concern in the soil science community. More recently there is evidence that soil science student numbers may be increasing, although additional information on this potential trend is desirable. One challenge soil science faces in the modern USA is finding an academic home, as soils are taught by a wide range of fields and soils classes are taken by students in many fields of study, including soil science, a range of agricultural programs, environmental science, environmental health, engineering, geology, geography, and others.

    Building on Watzlawick's observations of certain similarities between judo and brief strategic therapy, this paper develops theoretic and pragmatic parallels between brief strategic therapy and a sophisticated martial art system, Aikido. After presenting the contextual similarities of the two conceptual systems as parallel "challenges" to the therapist and Aikidoist to effect change, the similarities in basic principles of practice are presented. The similarities in the philosophical and attitudinal positions of these conceptual systems are then delineated, followed by a case example that integrates the various concepts in the paper.

  14. Three brief assessments of math achievement.

    Science.gov (United States)

    Steiner, Eric T; Ashcraft, Mark H

    2012-12-01

    Because of wide disparities in college students' math knowledge-that is, their math achievement-studies of cognitive processing in math tasks also need to assess their individual level of math achievement. For many research settings, however, using existing math achievement tests is either too costly or too time consuming. To solve this dilemma, we present three brief tests of math achievement here, two drawn from the Wide Range Achievement Test and one composed of noncopyrighted items. All three correlated substantially with the full achievement test and with math anxiety, our original focus, and all show acceptable to excellent reliability. When lengthy testing is not feasible, one of these brief tests can be substituted.

    Identifying fundamental drivers of science and developing predictive models to capture its evolution are instrumental for the design of policies that can improve the scientific enterprise-for example, through enhanced career paths for scientists, better performance evaluation for organizations hosting research, discovery of novel effective funding vehicles, and even identification of promising regions along the scientific frontier. The science of science uses large-scale data on the production of science to search for universal and domain-specific patterns. Here, we review recent developments in this transdisciplinary field.

  9. A Brief History of Soils and Human Health Studies

    Science.gov (United States)

    Brevik, Eric C.; Sauer, Thomas J.

    2013-04-01

    The idea that there are links between soils and human health is an ancient one. The Bible depicts Moses as understanding that fertile soil was essential to the well-being of his people in approximately 1400 B.C. as they entered Canaan, and in 400 B.C. Hippocrates provided a list of things that should be considered in a proper medical evaluation, including the ground. Moving into the 18th and 19th Centuries, some North American farmers have been documented as recognizing a link between soils and human vitality. However, the recognition of links between soils and human health by these early people was based on casual observations leading to logical conclusions rather than scientific investigation. In the 1900s the idea that soils influence human health gained considerable traction. At least three chapters in the 1938 USDA Yearbook of Agriculture included recognition of the importance of soil as the origin of many of the mineral elements necessary for human health and in the 1957 USDA Yearbook of Agriculture scientists realized that soils were not only important in the supply of essential nutrients, but that they could also supply toxic levels of elements to the human diet. The U.S. Department of Agriculture established the Plant, Soil and Nutrition Research Unit (PSNRU) on the Cornell University campus in 1940 with a mission to conduct research at the interface of human nutrition and agriculture to improve the nutritional quality and health-promoting properties of food crops. A major human health breakthrough in 1940 was the isolation of antibiotic compounds from soil organisms by the research group at Rutgers University lead by Selman Waksman. Soil microorganisms create antibiotic compounds in an effort to gain a competitive advantage in the soil ecosystem. Humans have been able to isolate those compounds and use them advantageously in the fight against bacterial infections. Waksman was awarded the Nobel Prize in Physiology or Medicine in 1952, the only soil

    After the accident of the Fukushima Daiichi Nuclear Power Plant, enormous amount of waste contaminated by radioactive cesium has been produced. Burned ash that contained radiocesium ( 137 Cs) more than 8,000 Bq/kg will be stored at the not-yet-located final deposit. Until the final deposit is finally constructed, however, the radioactive ash should be stored safely at temporal deposits. Inhabitants briefing sessions for locating the temporal deposits are held at many places in the east Japan. But, they met difficulty in establishing smooth communication between citizens and the administrations. In this paper, I classify the questions arose from citizens at the inhabitants briefing session at Tokatsu area, Chiba prefecture, and discuss what role could scientists and science communicators play at this session. In addition, I classified the voices of inhabitants reported in the newspapers and discuss the media bias. (author)

    The decision was made to try to increase the luminosity of CESR as high as possible with a single magnet ring. This, the Phase-III plan, can yield a luminosity of 1 x 10 33 with 45 bunches in each beam for a total current in each beam of 0.5 amperes. This plan utilizes four superconducting, single cell cavities. The use of only four SC accelerating cells as compared to the present twenty normal conducting cells decreases both the broad band and narrow band impedances sufficiently to allow stable operation at these half ampere current levels.

    2008-12-01

    Full Text Available In anticipation of a new era of synchrotron radiation sources based on energy recovery linac techniques, we designed, built, and tested a short undulator magnet prototype whose features make optimum use of the unique conditions expected in these facilities. The prototype has pure permanent magnet (PPM structure with 24 mm period, 5 mm diameter round gap, and is 30 cm long. In comparison with conventional undulator magnets it has the following: (i full x-ray polarization control.—It may generate varying linear polarized as well as left and right circular polarized x rays with photon flux much higher than existing Apple-II–type devices. (ii 40% stronger magnetic field in linear and approximately 2 times stronger in circular polarization modes. This advantage translates into higher x-ray flux. (iii Compactness.—The prototype can be enclosed in a ∼20  cm diameter cylindrical vacuum vessel. These advantages were achieved through a number of unconventional approaches. Among them is control of the magnetic field strength via longitudinal motion of the magnet arrays. The moving mechanism is also used for x-ray polarization control. The compactness is achieved using a recently developed permanent magnet soldering technique for fastening PM blocks. We call this device a “Delta” undulator after the shape of its PM blocks. The presented article describes the design study, various aspects of the construction, and presents some test results.

    The identification of frail older persons is a public health priority. Frailty is defined as an extreme vulnerability of the organism to endogenous and exogenous stressors, a syndrome that exposes the individual at higher risk of negative health-related outcomes as well as a transition phase between successful aging and disability. The theoretical concept of frailty is largely agreed, its practical translation still presents some limitations due to the existence of multiple tools and operational definition. In this brief review, we would like to clarify the frailty concept regarding scientific literature.

    The participants in the NIMH-MATRICS Consensus Development Conference on Negative Symptoms recommended that an instrument be developed that measured blunted affect, alogia, asociality, anhedonia, and avolition. The Brief Negative Symptom Scale (BNSS) is a 13-item instrument designed for clinical trials and other studies that measures these 5 domains. The interrater, test-retest, and internal consistency of the instrument were strong, with respective intraclass correlation coefficients of 0.93 for the BNSS total score and values of 0.89-0.95 for individual subscales. Comparisons with positive symptoms and other negative symptom instruments supported the discriminant and concurrent validity of the instrument.

  7. Observation of Χb and Χb' production in exclusive decays of the Υ' and Υ'' with the CUSB detector at the Cornell e+e- storage ring

    1984-01-01

    The nonmagnetic CUSB detector at the Cornell Electron Storage Ring (CESR) has been used to study both the exclusive cascade decays Τ'→γΧ b →γγΤ→γγ(μ + μ - or e + e - ), Τ''→γΧ b '→γγΤ'→γγ(μ + μ - or e + e - ), Τ''→γΧ b '→γγΤ→γγ(μ + μ - or e + e - ) and the inclusive photon spectra from radiative Τ' and Τ'' decays. In a data sample of ≅ 170,000 Τ' resonance decays and ≅ 50,000 Τ'' resonance decays evidence for Χ b and Χ b ' production has been found in both analyses. From the line positions in the photon spectra the Χ b masses have been determined to be at M(1 3 P 0 )=(9,873±5) MeV, M(1 3 P 1 )=(9,894±2) MeV and M(1 3 P 2 )=(9,915±2) MeV, the Χ b ' masses at M(2 3 P 0 )=(10,233±5) MeV, M(2 3 P 1 )=(10,256±2) MeV and M(2 3 P 2 )=(10,271±2) MeV. The spin-averaged center-of-gravities have been obtained at M(1 3 P cog )=(9,904±1.5) MeV and M(2 3 P cog )=(10,262±1.5) MeV. The product branching ratios for the three exclusive decay modes are (3.2±0.7)%, (5.0±2.1)% and (3.6±1.1)%, respectively. For the inclusive transitions Τ'→γΧ b and Τ''→γΧ b ', branching ratios of (15.5±2.5)% and (35.9±3)% have been measured. The results are in good agreement with predictions of potential models based on perturbative QCD. (orig.) [de

    Avoidant personality disorder (APD) is associated with a high level of impairment in multiple areas of functioning. However, research on the treatment of APD is scarce, and there is an absence of empirically evaluated effective treatment approaches available. This study offers a preliminary investigation of the use of brief cognitive therapy to treat APD. Two individuals, both with a principal diagnosis of APD, but who also possessed a number of comorbidities, participated in 12 weekly sessions. A series of diagnostic symptom severity, global functioning, and self-report measures were completed at pretreatment, posttreatment and at 6-week follow-up. In addition, regular monitoring of each participant's strength of belief in 4 personally identified cognitions associated with APD was completed. Reductions in APD symptoms, associated negative affect, and increases to quality of life were observed for both participants at posttreatment and follow-up phases. Results suggest that brief cognitive therapy may be an effective treatment for APD and that further studies with larger samples are warranted.

    The first part of the paper gives a brief description of decommissioning scenarios and models of financing the decommissioning of NPPs. The second part contains a review of decommissioning costs for certain PWR plants with a brief description of methods used for that purpose. The third part of the paper the authors dedicated to the assessment of decommissioning costs for Krsko NPP. It does not deal with ownership relations and obligations ensuing from them. It starts from the simple point that decommissioning is an structure of the decommissioning fund is composed of three basic cost items of which the first refers to radioactive waste management, the second to storage and disposal of the spent nuclear fuel and the third to decommissioning itself. The assessment belongs to the category of preliminary activities and as such has a limited scope and meaning. Nevertheless, the authors believe that it offers a useful insight into the basic costs that will burden the decommissioning fund of Krsko NPP. (author)

  11. Fascinating Magnetic Energy Storage Nanomaterials: A Brief Review.

    Science.gov (United States)

    Sreenivasulu, Kummari V; Srikanth, Vadali V S S

    2017-07-10

    In this brief review, the importance of nanotechnology in developing novel magnetic energy storage materials is discussed. The discussion covers recent patents on permanent magnetic materials and especially covers processing of permanent magnets (rare-earth and rare-earth free magnets), importance of rare-earth permanent magnets and necessity of rare-earth free permanent magnets. Magnetic energy storage materials are those magnetic materials which exhibit very high energy product (BH)max (where B is the magnetic induction in Gauss (G) whereas H is the applied magnetic field in Oersted (Oe)). (BH)max is the direct measure of the ability of a magnetic material to store energy. In this context, processing of magnetic energy storage composite materials constituted by soft and hard magnetic materials played a predominant role in achieving high (BH)max values due to the exchange coupling phenomenon between the soft and hard magnetic phases within the composite. Magnetic energy storage composites are normally composed of rare-earth magnetic materials as well as rare-earth free magnetic materials. Nanotechnology's influence on the enhancement of energy product due to the exchange coupling phenomenon is of great prominence and therefore discussed in this review.

    Atomic layer deposition (ALD) is a technique increasingly used in nanotechnology and ultrathin film deposition; it is ideal for films in the nanometer and Angstrom length scales. ALD can effectively be used to modify the surface chemistry and functionalization of engineering-related and biologically important surfaces. It can also be used to alter the mechanical, electrical, chemical, and other properties of materials that are increasingly used in biomedical engineering and biological sciences. ALD is a relatively new technique for optimizing materials for use in bio-nanotechnology. Here, after a brief review of the more widely used modes of ALD and a few of its applications in biotechnology, selected results that show the potential of ALD in bio-nanotechnology are presented. ALD seems to be a promising means for tuning the hydrophilicity/hydrophobicity characteristics of biomedical surfaces, forming conformal ultrathin coatings with desirable properties on biomedical substrates with a high aspect ratio, tuning the antibacterial properties of substrate surfaces of interest, and yielding multifunctional biomaterials for medical implants and other devices.

    Beginning with OSTA-1 in November 1981 and ending with Neurolab in March 1998, a total of 36 Shuttle missions carried various Spacelab components such as the Spacelab module, pallet, instrument pointing system, or mission peculiar experiment support structure. The experiments carried out during these flights included astrophysics, solar physics, plasma physics, atmospheric science, Earth observations, and a wide range of microgravity experiments in life sciences, biotechnology, materials science, and fluid physics which includes combustion and critical point phenomena. In all, some 764 experiments were conducted by investigators from the U.S., Europe, and Japan. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and if appropriate, where the knowledge they produced has been applied.

  3. Mean Field Games Models-A Brief Survey

    Gomes, Diogo A.; Saú de, Joã o

    2013-01-01

    The mean-field framework was developed to study systems with an infinite number of rational agents in competition, which arise naturally in many applications. The systematic study of these problems was started, in the mathematical community by Lasry and Lions, and independently around the same time in the engineering community by P. Caines, Minyi Huang, and Roland Malhamé. Since these seminal contributions, the research in mean-field games has grown exponentially, and in this paper we present a brief survey of mean-field models as well as recent results and techniques. In the first part of this paper, we study reduced mean-field games, that is, mean-field games, which are written as a system of a Hamilton-Jacobi equation and a transport or Fokker-Planck equation. We start by the derivation of the models and by describing some of the existence results available in the literature. Then we discuss the uniqueness of a solution and propose a definition of relaxed solution for mean-field games that allows to establish uniqueness under minimal regularity hypothesis. A special class of mean-field games that we discuss in some detail is equivalent to the Euler-Lagrange equation of suitable functionals. We present in detail various additional examples, including extensions to population dynamics models. This section ends with a brief overview of the random variables point of view as well as some applications to extended mean-field games models. These extended models arise in problems where the costs incurred by the agents depend not only on the distribution of the other agents, but also on their actions. The second part of the paper concerns mean-field games in master form. These mean-field games can be modeled as a partial differential equation in an infinite dimensional space. We discuss both deterministic models as well as problems where the agents are correlated. We end the paper with a mean-field model for price impact. © 2013 Springer Science+Business Media New York.

    Congress has mandated a more comprehensive management of hazardous wastes with the Resource Conservation and Recovery Act (RCRA), the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or ''Superfund'') and the Superfund Amendment and Reauthorization Act (SARA). This mandate includes restoration of disposal sites contaminated through past disposal practices. This mandate applies to facilities operated for and by the Department of Energy (DOE), just as it does to industrial and other institutions. To help implement the CERCLA/SARA remedial investigation and feasibility study (RI/FS) process in a consistent, timely, and cost-effective manner, a methodology needs to be developed that will allow definition, sorting, and screening of remediation technologies for each operable unit (waste site). This need is stated specifically in Section 2.2.2.1 of the October 1989 Applied Research, Development, Demonstration, Testing, and Evaluation (RDDT ampersand E) Plan of the DOE. This Briefing Paper is prepared to respond to this need. 1 fig

    There are several unique psychiatric disorders that are likely to present to a dermatologist because of their accompanying skin complaints. Delusions of parasitosis (DP) is a fixed, false belief of parasitic infestation that may lead patients to compulsively self-mutilate while attempting to remove the non-existent parasites. Morgellons disease is a controversial condition characterized by a fixed belief that fibers that are imbedded or extruding from the skin; this condition is likely in the spectrum of DP. Body dysmorphic disorder (BDD) is a preoccupation with an imagined defect in appearance that causes significant distress and is associated with time consuming rituals, isolation, depression, and increased risk of suicide. Olfactory reference syndrome (ORS) is a preoccupation with body odor leading to the stigmata of shame, embarrassment, and social isolation. This brief review examines each of these conditions and their management because any one of them may present to a dermatologist.

    A capacitated pregnant woman has a nearly unqualified right to refuse a cesarean section. Her right to say "no" takes precedence over clinicians' preferences and even over clinicians' concerns about fetal health. Leading medical societies, human rights organizations, and appellate courts have all endorsed this principle. Nevertheless, clinicians continue to limit reproductive liberty by forcing and coercing women to have unwanted cesareans. This "Legal Briefing" reviews recent court cases involving this type of obstetric violence. I have organized these court cases into the following six categories: 1. Epidemic of Unwanted Cesareans 2. Court-Ordered Cesareans 3. Physician-Coerced Cesareans 4. Physician-Ordered Cesareans 5. Cesareans for Incapacitated Patients 6. Cesareans for Patients in a Vegetative State or Who Are Brain Dead.

  8. History of Hanford Site Defense Production (Brief)

    International Nuclear Information System (INIS)

    GERBER, M.S.

    2001-01-01

    This paper acquaints the audience with the history of the Hanford Site, America's first full-scale defense plutonium production site. The paper includes the founding and basic operating history of the Hanford Site, including World War II construction and operations, three major postwar expansions (1947-55), the peak years of production (1956-63), production phase downs (1964-the present), a brief production spurt from 1984-86, the end of the Cold War, and the beginning of the waste cleanup mission. The paper also delineates historical waste practices and policies as they changed over the years at the Hanford Site, past efforts to chemically treat, ''fractionate,'' and/or immobilize Hanford's wastes, and resulting major waste legacies that remain today. This paper presents original, primary-source research into the waste history of the Hanford Site. Finally, the paper places the current Hanford Site waste remediation endeavors in the broad context of American and world history

  9. Affordances for robots: a brief survey

    2012-12-01

    Full Text Available In this paper, we consider the influence of Gibson's affordance theory on the design of robotic agents. Affordance theory (and the ecological approach to agent design in general has in many cases contributed to the development of successful robotic systems; we provide a brief survey of AI research in this area. However, there remain significant issues that complicate discussions on this topic, particularly in the exchange of ideas between researchers in artificial intelligence and ecological psychology. We identify some of these issues, specifically the lack of a generally accepted definition of "affordance" and fundamental differences in the current approaches taken in AI and ecological psychology. While we consider reconciliation between these fields to be possible and mutually beneficial, it will require some flexibility on the issue of direct perception.

    2017-01-01

    What is mechanical engineering? What a mechanical engineering does? How did the mechanical engineering change through ages? What is the future of mechanical engineering? This book answers these questions in a lucid manner. It also provides a brief chronological history of landmark events and answers questions such as: When was steam engine invented? Where was first CNC machine developed? When did the era of additive manufacturing start? When did the marriage of mechanical and electronics give birth to discipline of mechatronics? This book informs and create interest on mechanical engineering in the general public and particular in students. It also helps to sensitize the engineering fraternity about the historical aspects of engineering. At the same time, it provides a common sense knowledge of mechanical engineering in a handy manner.

  11. Brief wakeful resting can eliminate directed forgetting.

    Science.gov (United States)

    Schlichting, Andreas; Bäuml, Karl-Heinz T

    2017-02-01

    When cued to intentionally forget previously encoded memories, participants typically show reduced recall of the memories on a later recall test. We examined how such directed forgetting is affected by a brief period of wakeful resting between encoding and test. Encoding was followed by a "passive" wakeful resting period in which subjects heard emotionally neutral music or perceived neutral pictures, or it was followed by an "active" distraction period in which subjects were engaged in counting or calculation tasks. Whereas typical directed forgetting was present after active distraction, the forgetting was absent after wakeful resting. The findings indicate that the degree to which people can intentionally forget memories is influenced by the cognitive activity that people engage in shortly after learning takes place. The results provide first evidence on the interplay between wakeful resting and intentional forgetting.

  12. A brief review on anterior urethral strictures

    2018-04-01

    Full Text Available The treatment of urethral strictures remains a challenging field in urology even though there are a variety of procedures to treat it at present, as no one approach is superior over another. This paper reviewed the surgical options for the management of different sites and types of anterior urethral stricture, providing a brief discussion of the controversies regarding this issue and suggesting possible future advancements. Among the existing procedures, simple dilation and direct vision internal urethrotomy are more commonly used for short urethral strictures ( <1 cm, soft and no previous intervention. Currently, urethroplasty using buccal mucosa or penile skin is the most widely adopted clinical techniques and have proved successful. Nonetheless, complications such as donor site morbidity remain problem. Tissue engineering techniques are considered as a promising solution for urethral reconstruction, but require further investigation, as does stem cell therapy.

    Haythronthwaite, J A; Lawrence, J W; Fauerbach, J A

    2001-01-01

    This study tested the efficacy of 2 brief cognitive interventions in supplementing regular medical treatment for pain during burn dressing change. Forty-two burn inpatients were randomly assigned to 3 groups: sensory focusing, music distraction, and usual care. Patients reported pain, pain relief satisfaction with pain control, and pain coping strategies. The sensory focusing group reported greater pain relief compared to the music distraction group and a reduction in remembered pain compared to the usual care group, although group differences were not observed on serial pain ratings. In addition, after controlling for burn size and relevant covariates, regression analyses indicated that catastrophizing predicted pain, memory for pain, and satisfaction with pain control. Refinement of the sensory focusing intervention is warranted to reduce catastrophic thinking and improve pain relief

    In this article, we provide a brief tutorial on the estimation, analysis, and simulation on attitude networks using the programming language R. We first discuss what a network is and subsequently show how one can estimate a regularized network on typical attitude data. For this, we use open-access data on the attitudes toward Barack Obama during the 2012 American presidential election. Second, we show how one can calculate standard network measures such as community structure, centrality, and connectivity on this estimated attitude network. Third, we show how one can simulate from an estimated attitude network to derive predictions from attitude networks. By this, we highlight that network theory provides a framework for both testing and developing formalized hypotheses on attitudes and related core social psychological constructs.

    1982-01-01

    An evaluation of high-resolution geophysical techniques which can be used to characterize a nulcear waste disposal site is being conducted by the Lawrence Livermore National Laboratory (LLNL) at the request of the US Nuclear Regulatory Commisson (NRC). LLNL is involved in research work aimed at evaluating the current capabilities and limitations of geophysical methods used for site selection. This report provides a brief overview of the capabilities and limitations associated with this technology and explains how our work addresses some of the present limitations. We are examining both seismic and electromagnetic techniques to obtain high-resolution information. We are also assessing the usefulness of geotomography in mapping fracture zones remotely. Finally, we are collecting core samples from a site in an effort to assess the capability of correlating such geophysical data with parameters of interest such as fracture continuity, orientation, and fracture density

    1986-01-01

    The DWK is now planning the construction and operation of a facility for the reprocessing of spent fuel elements and the fabrication of mixed-oxide fuel elements which will initially have an average daily throughput of 2 tons (t) of nuclear fuel. The application required by the Atomic Law was submitted to the Bavarian State Ministry for State Development and Environmental Matters on October 28, 1982. According to Par. 3, Section 1, No. 1 of the Atomic Law Procedural Ordinance such an application for permission in accordance with par. 7 AtL must explicitly be accompanied by a safety report which shall make it possible for third parties to make a judgment whether the impacts associated with the facility and its operation could damage their rights. The safety report is intended to present and explain the concept of the facility, the safety-technological design bases, and the operation of the plant, including its operation and safety systems and the impacts and proposed preventive measures. In addition to the detailed presentations in the safety report, Par. 3 of the Atomic Law Procedural Ordinance also requires a brief description of the plant designed for general public understanding, suitable for the design, which will also explain the expected impacts on the general environment and the surrounding area. Hence the brief description presents and explains the following matters: the site; the technology and state of the art for reprocessing of spent nuclear fuel; the structure and function of the proposed facility; safety provisions of the proposed facility and the management of perturbations in operation; the impacts of the facility and its operation on the environment; measures to be taken for dealing with the radioactive wastes; and provisions for ultimate shut-down of the facility

    2014-01-01

    Full Text Available Academic preparation of science researchers and/or human or veterinary medicine clinicians through the science, technology, engineering, and mathematics (STEM curriculum has usually focused on the students (1 acquiring increased disciplinary expertise, (2 learning needed methodologies and protocols, and (3 expanding their capacity for intense, persistent focus. Such educational training is effective until roadblocks or problems arise via this highly-learned approach. Then, the health science trainee may have few tools available for effective problem solving. Training to achieve flexibility, adaptability, and broadened perspectives using contemplative practices has been rare among biomedical education programs. To address this gap, a Cornell University-based program involving formal biomedical science coursework, and health science workshops has been developed to offer science students, researchers and health professionals a broader array of personal, contemplation-based, problem-solving tools. This STEM educational initiative includes first-person exercises designed to broaden perceptional awareness, decrease emotional drama, and mobilize whole-body strategies for creative problem solving. Self-calibration and journaling are used for students to evaluate the personal utility of each exercise. The educational goals are to increase student self-awareness and self-regulation and to provide trainees with value-added tools for career-long problem solving. Basic elements of this educational initiative are discussed using the framework of the Tree of Contemplative Practices.

    Iyengar, P.K.

    2009-01-01

    Few scientists one knows of, have gone out of their way to educate the public-especially those involved in making policies at the government level-on what nuclear energy is all about and how it is produced. One might begin at the beginning and ask what the basic principles of scientific research are, how they are developed and what the methodology of converting science into technology is. Equally relevantly, how can one sensitise the administration, not to speak of the average citizen, in supporting science and technology. This work is divided into nine chapters. The first one discusses what science really is. The second introduces the reader to nuclear science and technology. The third progressively deals with Indian effort in developing nuclear science and the astounding amount of organisational effort involved. The fourth refers to nuclear testing, a somewhat controversial subject. The fifth addresses itself to the problem of nuclear non-proliferation, yet another controversial subject, but which Dr Iyengar deals with commendable objectivity. The last three chapters concern administrative reforms

    Fok, Carlotta Ching Ting; Allen, James; Henry, David

    2014-02-01

    The Relationship dimension of the Family Environment Scale, which consists of the Cohesion, Expressiveness, and Conflict subscales, measures a person's perception of the quality of his or her family relationship functioning. This study investigates an adaptation of the Relationship dimension of the Family Environment Scale for Alaska Native youth. The authors tested the adapted measure, the Brief Family Relationship Scale, for psychometric properties and internal structure with 284 12- to 18-year-old predominately Yup'ik Eskimo Alaska Native adolescents from rural, remote communities. This non-Western cultural group is hypothesized to display higher levels of collectivism traditionally organized around an extended kinship family structure. Results demonstrate a subset of the adapted items function satisfactorily, a three-response alternative format provided meaningful information, and the subscale's underlying structure is best described through three distinct first-order factors, organized under one higher order factor. Convergent and discriminant validity of the Brief Family Relationship Scale was assessed through correlational analysis.

  4. Physical experience enhances science learning.

    Kontra, Carly; Lyons, Daniel J; Fischer, Susan M; Beilock, Sian L

    2015-06-01

    Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning. © The Author(s) 2015.

    2015-10-01

    As energy is now a matter of concern on many respects (scarcity, prices, technical innovations, pollution and climate change, national dependency, poverty, security, national and European policy), the author proposes an overview of the ways social sciences address these issues. He discusses the main guidelines of a social science of energy, outlines why and how political and social sciences are interested in energy, proposes an overview analytical tools these disciplines may use to address these issues, and an overview of addressed themes and raised questions. These aspects are addressed by outlining emerging social concerns, by discussing the issue of social acceptability or non-acceptability of energy infrastructures and services, by commenting the behaviour of households in front of services provided by smart grids, by discussing the study of the rationale of action in the field of energy (comfort, economy, ecology, and others), by commenting the relationship between energy-related behaviours and sobriety, by discussing some elements of analysis of energy governance (case of eco-districts, example of the Bonne eco-district in Grenoble, emergence on non conventional governance modes). The author finally proposes an overview of some elements of energy political science in the context of energy transition, notably ways to address energy poverty and energy dependency

    2018-05-03

    Ionic liquids (ILs) are a vast class of organic non-aqueous electrolytes whose interaction with biomolecules is receiving great attention for potential applications in bio-nano-technology. Recently, it has been shown that ILs can affect protein amyloidogenesis. Whereas some ILs favour the aggregation of proteins into amyloids, others inhibit their formation. Moreover, ILs can dissolve mature fibrils and restore the protein biochemical function. In this letter, we present a brief state-of-the-art summary of this emerging field that holds the promise of important developments both in basic science and in applications from bio-medicine to material science, and bio-nano-technology. The huge variety of ILs offers a vast playground for future studies and potential applications.

  19. What does "brief" mean? A theoretical critique of the concept of brief therapy from a psychoanalytic viewpoint.

    Science.gov (United States)

    Migone, Paolo

    2014-08-01

    The concept of "brief therapy" contains internal contradictions. The techniques suggested by brief therapists are the same techniques that have been discussed historically in debates on theory of technique, both within and without psychoanalysis (e.g., the experiential factor at the center of the Freud-Ferenczi confrontation is also an important aspect of Gestalt therapy). A time limit is the only operational criterion that allows a rigorous definition of brief therapy; without this criterion it is impossible to discriminate between "brief" and simply "good" therapies (i.e., those in which patients are successfully treated in a short time). An important question is why, with a given patient, a therapist should decide, a priori, to terminate a treatment within a set time. Two clinical examples are presented, illustrating the usefulness of Eissler's concept of parameters as a heuristic framework to identify the potentially defensive nature of both "brief" and "long-term" therapy. © 2014 by the American Psychoanalytic Association.

The paper includes the founding and basic operating history of the Hanford Site, including World War II construction and operations, three major postwar expansions (1947-55), the peak years of production (1956-63), production phase downs (1964-the present), a brief production spurt from 1984-86, the end of the Cold War, and the beginning of the waste cleanup mission. The paper also delineates historical waste practices and policies as they changed over the years at the Hanford Site, past efforts to chemically treat, ''fractionate,'' and/or immobilize Hanford's wastes, and resulting major waste legacies that remain today. This paper presents original, primary-source research into the waste history of the Hanford Site. Finally, the paper places the current Hanford Site waste remediation endeavors in the broad context of American and world history.

  1. Research briefing on high-temperature superconductivity

    Science.gov (United States)

    1987-10-01

    The research briefing was prepared in response to the exciting developments in superconductivity in ceramic oxide materials announced earlier in 1987. The panel's specific charge was to examine not only the scientific opportunities in high-temperature superconductivity but also the barriers to commercial exploitation. While the base of experimental knowledge on the superconductors is growing rapidly, there is as yet no generally accepted theoretical explanation of their behavior. The fabrication and processing challenges presented by the materials suggest that the period or precommercial exploration for applications will probably extend for a decade or more. Near term prospects for applications include magnetic shielding, the voltage standard, superconducting quantum interference devices, infrared sensors, microwave devices, and analog signal processing. The panel also identified a number of longer-term prospects in high-field and large-scale applications, and in electronics. The United States' competitive position in the field is discussed, major scientific and technological objectives for research and development identified, and concludes with a series of recommendations.

    2006-04-01

    Full Text Available Neither the layman nor the specialist, in general, have any knowledge of the historical circumstances underlying the genesis of the idea of the Black Hole. Essentially, almost all and sundry simply take for granted the unsubstantiated allegations of some ostentatious minority of the relativists. Unfortunately, that minority has been rather careless with the truth and is quite averse to having its claims corrected, notwithstanding the documentary evidence on the historical record. Furthermore, not a few of that vainglorious and disingenuous coterie, particularly amongst those of some notoriety, attempt to dismiss the testimony of the literature with contempt, and even deliberate falsehoods, claiming that history is of no importance. The historical record clearly demonstrates that the Black Hole has been conjured up by combination of confusion, superstition and ineptitude, and is sustained by widespread suppression of facts, both physical and theoretical. The following essay provides a brief but accurate account of events, verifiable by reference to the original papers, by which the scandalous manipulation of both scientific and public opinion is revealed

    2017-07-01

    Teaching is a complex mission that requires not only the theoretical knowledge transmission, but furthermore requires to provide the students the necessary skills for solving real problems in their respective professional activities where complex issues and problems must be frequently faced. Over more than twenty years we have been experiencing an increase in scholar failure in the scientific area of mathematics, which means that Teaching Mathematics and related areas can be even a more complex and hard task. Scholar failure is a complex phenomenon that depends on various factors as social factors, scholar factors or biophysical factors. After numerous attempts made in order to reduce scholar failure our goal in this paper is to understand the role of "Problem Based Learning" and how this methodology can contribute to the solution of both: increasing mathematical courses success and increasing skills in the near future professionals in Portugal. Before designing a proposal for applying this technique in our institutions, we decided to conduct a survey to provide us with the necessary information about and the respective advantages and disadvantages of this methodology, so this is the brief review aim.

The oil and gas sectors are dominated by the Turkish Petroleum Corporation, a public enterprise dealing with exploration and production, and the State Pipeline Corporation which deals with energy transmission. They are also the key buyers of oil and gas equipment in Turkey. There are several pipelines connecting countries bordering the Caspian Sea. Opportunities exist in the areas of engineering consulting as well as contracting services for oil and gas pipeline transmission and distribution. Other opportunities lie in the area of pipeline construction, rehabilitation, materials, equipment, installation, and supervisory control and data acquisition (SCADA) systems. Currently, the major players are suppliers from Italy, Germany, France, United States and Japan. Turkey has no trade barriers and imported equipment and materials are not subjected to any restriction. The oil and gas market in Turkey expected in increase by an average annual growth rate of 15 per cent from 2001 to 2003. A brief description of pipeline projects in Turkey was presented in this report along with a list of key contacts and support services. 25 refs., 1 append

    Solar storms, which are expected to increase as the Sun nears the most active phase of the solar cycle, can disrupt a variety of technologies on which society relies. Speakers at a 22 June briefing on Capitol Hill in Washington, D. C., focused on how space weather can affect the Global Positioning System (GPS), which is used in a wide range of industries, including commercial air travel, agriculture, national security, and emergency response. Rocky Stone, chief technical pilot for United Airlines, noted that GPS allows more aircraft to be in airspace, saves fuel, and helps aircraft move safely on runways. “Improvements in space weather forecasting need to be pursued,” he said. Precision GPS has also “changed the whole nature of farming,” said Ron Hatch, Director of Navigation Systems, NavCom Technology/John Deere. GPS makes it possible for tractors to be driven in the most efficient paths and for fertilizer and water to be applied precisely to the areas that most need them. Space weather-induced degradation of GPS signals can cause significant loss to farms that rely on GPS. Elizabeth Zimmerman, Deputy Associate Administrator for the Office of Response and Recovery at the Federal Emergency Management Agency (FEMA), described how FEMA relies on GPS for disaster recovery. The agency is developing an operations plan for dealing with space weather, she said.

  6. A brief history of mathematics in finance

    Full Text Available In the list of possible scapegoats for the recent financial crises, mathematics, in particular mathematical finance has been ranked, without a doubt, as the first among many and quants, as mathematicians are known in the industry, have been blamed for developing and using esoteric models which are believed to have caused the deepening of the financial crisis. However, as Lo and Mueller (2010 state “Blaming quantitative models for the crisis seems particularly perverse, and akin to blaming arithmetic and the real number system for accounting fraud.” Throughout the history, mathematics and finance have always been in a close relationship. Starting from Babylonians, through Thales, and then Fibonacci, Pascal, Fermat, Bernoulli, Bachelier, Wiener, Kolmogorov, Ito, Markowitz, Black, Scholes, Merton and many others made huge contributions to the development of mathematics while trying to solve finance problems. In this paper, we present a brief historical perspective on how the development of finance theory has influenced and in turn been influenced by the development of mathematical finance theory.

  7. Plasma Science Committee (PLSC) and study on new opportunities in plasma science and technology

    International Nuclear Information System (INIS)

    1992-01-01

    The Plasma Science Committee (PLSC) of the National Research Council (NRC) is charged with monitoring the health of the field of plasma science in the United States. Accordingly, the Committee identifies and examines both broad and specific issues affecting the field. Regular meetings, teleconferences, briefings from agencies and the scientific community, the formation of study panels to prepare reports, and special symposia are among the mechanisms used by the PLSC to meet its charge. This progress report presents a review of PLSC activities from July 15, 1991 to May 31, 1992. The details of prior activities are discussed in earlier reports. This report also includes the status of activities associated with the PLSC study on opportunities in plasma science and technology. During the above period, the PLSC has continued to track and participate in, when requested, discussions on the health of the field. Much of the perspective of the PLSC has been presented in the recently-published report Research Briefing on Contemporary Problems in Plasma Science. That report has served as the basis for briefings to representatives of the federal government as well as the community-at-large. In keeping with its charge to identify and highlight specific areas for scientific and technological opportunities, the PLSC completed publication of the report Plasma Processing of Materials: Scientific and Technological Opportunities and launched a study on new opportunities in plasma science and technology

    2010-04-15

    This technology brief on gas-fired power is part of a series produced by the IEA called the energy technology data source (E-Tech-DS). The E-Tech-DS series consists of a number of 5-10 page technology briefs similar to the IEA Energy Technology Essentials. Based on the data collected for the models that the Energy Technology Systems Analysis Programme (ETSAP) is known for, ETSAP also prepares technology briefs, called E-TechDS. The E-TechDS briefs are standardized presentations of basic information (process, status, performance, costs, potential, and barriers) for key energy technology clusters. Each brief includes an overview of the technology, charts and graphs, and a summary data table, and usually ending with some key references and further information. The E TechDS briefs are intended to offer essential, reliable and quantitative information to energy analysts, experts, policymakers, investors and media from both developed and developing countries. This specific brief focuses on the state of combined-cycle gas turbines (CCGT). CCGT's have become the technology of choice for new gas-fired power plants since the 1990's.

    2017-09-01

    Elemental carbon has been known from time immemorial in its forms of diamond and graphite, while the Industrial Revolution was powered by coal. The molecular structures of diamond and graphite were established following the inception of X-ray crystallography while the complex natures of charcoal and coal have been investigated for 100 years. Recent developments in activated charcoal are described in an article in this issue of Science Progress. However, no-one could have guessed that carbon would have presented such structural surprises as those of C60 fullerene, carbon nanotubes, and graphene. Materials science has benefited from the discovery of carbon fibres, and our understanding of the spectroscopy and bonding in the simplest carbon molecule, C2, has reached new depths.

    Agricultural systems science generates knowledge that allows researchers to consider complex problems or take informed agricultural decisions. The rich history of this science exemplifies the diversity of systems and scales over which they operate and have been studied. Modeling, an essential tool in agricultural systems science, has been accomplished by scientists from a wide range of disciplines, who have contributed concepts and tools over more than six decades. As agricultural scientists now consider the "next generation" models, data, and knowledge products needed to meet the increasingly complex systems problems faced by society, it is important to take stock of this history and its lessons to ensure that we avoid re-invention and strive to consider all dimensions of associated challenges. To this end, we summarize here the history of agricultural systems modeling and identify lessons learned that can help guide the design and development of next generation of agricultural system tools and methods. A number of past events combined with overall technological progress in other fields have strongly contributed to the evolution of agricultural system modeling, including development of process-based bio-physical models of crops and livestock, statistical models based on historical observations, and economic optimization and simulation models at household and regional to global scales. Characteristics of agricultural systems models have varied widely depending on the systems involved, their scales, and the wide range of purposes that motivated their development and use by researchers in different disciplines. Recent trends in broader collaboration across institutions, across disciplines, and between the public and private sectors suggest that the stage is set for the major advances in agricultural systems science that are needed for the next generation of models, databases, knowledge products and decision support systems. The lessons from history should be

  20. Legal briefing: conscience clauses and conscientious refusal.

    Science.gov (United States)

    Pope, Thaddeus Mason

    2010-01-01

    This issue's "Legal Briefing" column covers legal developments pertaining to conscience clauses and conscientious refusal. Not only has this topic been the subject of recent articles in this journal, but it has also been the subject of numerous public and professional discussions. Over the past several months, conscientious refusal disputes have had an unusually high profile not only in courthouses, but also in legislative and regulatory halls across the United States. Healthcare providers' own moral beliefs have been obstructing and are expected to increasingly obstruct patients' access to medical services. For example, some providers, on ethical or moral grounds, have denied: (1) sterilization procedures to pregnant patients, (2) pain medications in end-of-life situations, and (3) information about emergency contraception to rape victims. On the other hand, many healthcare providers have been forced to provide medical treatment that is inconsistent with their moral beliefs. There are two fundamental types of conscientious objection laws. First, there are laws that permit healthcare workers to refuse providing - on ethical, moral, or religious grounds healthcare services that they might otherwise have a legal or employer-mandated obligation to provide. Second, there are laws directed at forcing healthcare workers to provide services to which they might have ethical, moral, or religious objections. Both types of laws are rarely comprehensive, but instead target: (1) certain types of healthcare providers, (2) specific categories of healthcare services, (3) specific patient circumstances, and (4) certain conditions under which a right or obligation is triggered. For the sake of clarity, I have grouped recent legal developments concerning conscientious refusal into eight categories: 1. Abortion: right to refuse 2. Abortion: duty to provide 3. Contraception: right to refuse 4. Contraception: duty to provide 5. Sterilization: right to refuse 6. Fertility, HIV, vaccines

  1. A brief examination of optical tagging technologies.

    Energy Technology Data Exchange (ETDEWEB)

    Ackermann, Mark R.; Cahill, Paul A. (Aspecular Optics, Dayton, OH); Drummond, Timothy J.; Wilcoxon, Jess Patrick

    2003-07-01

    Presented within this report are the results of a brief examination of optical tagging technologies funded by the Laboratory Directed Research and Development (LDRD) program at Sandia National Laboratories. The work was performed during the summer months of 2002 with total funding of $65k. The intent of the project was to briefly examine a broad range of approaches to optical tagging concentrating on the wavelength range between ultraviolet (UV) and the short wavelength infrared (SWIR, {lambda} < 2{micro}m). Tagging approaches considered include such things as simple combinations of reflective and absorptive materials closely spaced in wavelength to give a high contrast over a short range of wavelengths, rare-earth oxides in transparent binders to produce a narrow absorption line hyperspectral tag, and fluorescing materials such as phosphors, dies and chemically precipitated particles. One technical approach examined in slightly greater detail was the use of fluorescing nano particles of metals and semiconductor materials. The idea was to embed such nano particles in an oily film or transparent paint binder. When pumped with a SWIR laser such as that produced by laser diodes at {lambda}=1.54{micro}m, the particles would fluoresce at slightly longer wavelengths, thereby giving a unique signal. While it is believed that optical tags are important for military, intelligence and even law enforcement applications, as a business area, tags do not appear to represent a high on return investment. Other government agencies frequently shop for existing or mature tag technologies but rarely are interested enough to pay for development of an untried technical approach. It was hoped that through a relatively small investment of laboratory R&D funds, enough technologies could be identified that a potential customers requirements could be met with a minimum of additional development work. Only time will tell if this proves to be correct.

    Alcohol misuse is substantially influenced by social factors, but systematic assessments of social network drinking are typically lengthy. The goal of the present study was to provide further validation of a brief measure of social network alcohol use, the Brief Alcohol Social Density Assessment (BASDA), in a sample of emerging adults. Specifically, the study sought to examine the BASDA's convergent, criterion, and incremental validity in relation to well-established measures of drinking motives and problematic drinking. Participants were 354 undergraduates who were assessed using the BASDA, the Alcohol Use Disorders Identification Test (AUDIT), and the Drinking Motives Questionnaire. Significant associations were observed between the BASDA index of alcohol-related social density and alcohol misuse, social motives, and conformity motives, supporting convergent validity. Criterion-related validity was supported by evidence that significantly greater alcohol involvement was present in the social networks of individuals scoring at or above an AUDIT score of 8, a validated criterion for hazardous drinking. Finally, the BASDA index was significantly associated with alcohol misuse above and beyond drinking motives in relation to AUDIT scores, supporting incremental validity. Taken together, these findings provide further support for the BASDA as an efficient measure of drinking in an individual's social network. Methodological considerations as well as recommendations for future investigations in this area are discussed.

    2018-01-01

    Print pharmaceutical advertisements in the United States require inclusion of a brief summary of side effects, warnings, precautions, and contraindications from the labeling. The full package insert, which sponsors have traditionally used to fulfill the brief summary requirement, does not adhere to health literacy best practices, limiting its value to consumers. This study compared the understandability and usability of brief summaries in 3 formats designed to be more consumer friendly. Three brief summary formats were tested: (1) 2-column "Question and Answer"; (2) "Prescription Drug Facts Box," similar to current US over-the-counter drug facts labeling; and (3) "Health Literacy," based on clear communication principles. Researchers evaluated the formats using the Suitability Assessment of Materials (SAM) tool and conducted structured, scripted, one-on-one interviews (usability tests) with participants with estimated low to average education levels. This research was replicated across 2 therapeutic areas (type 2 diabetes and plaque psoriasis). SAM scores showed that the Health Literacy format outperformed the Question and Answer format and the Prescription Drug Facts Box format in both therapeutic areas, with both Health Literacy brief summaries rated on the SAM as "superior." Qualitative usability tests supported the SAM findings, with the Health Literacy format preferred consistently over the Question and Answer format, and more often than not over the Prescription Drug Facts Box format. Sponsors can employ a user-tested Health Literacy format to improve the understandability and usability of brief summaries with patients.

    2001-05-01

    Quick Use Earth Study Tool (QUEST) is an experimental educational interface to the Cornell University's Geoscience Information System (http://atlas.geo.cornell.edu). The information system currently includes more than 100 geographic, geologic, and geophysical data sets along with World Wide Web based interactive mapping tools for data display and analysis. The system is GIS based and accessible via any web browser that support Java applets. QUEST is the companion module that has been developed to assist educators who wish to use these data to their fullest potential, providing tutorials, sample exercises, and suggested projects. Clearly, students learn best when they engage in the practice of science. One means to accomplish this is to have students access primary scientific data. Our experience suggests that a structured exploration of original data sets enhances student learning. For this reason we have selected a subset of Cornell's available geoscience data, and have designed a series of activities that allow students to explore dynamic Earth processes. Currently, these data include the ISC seismicity catalog, volcanism data from the Smithsonian Institution, and digital topography from the USGS and NOAA. The QUEST interface allows students to query the data sets based on a variety of criteria (e.g., earthquakes can be sorted by date, magnitude, depth, and location), or perform computations on data (e.g., sea level can be interactively mapped at any elevation on the DEM). Because the system is GIS-based, multiple data sets can be displayed simultaneously in order for users to examine the spatial relationships between geological features. Users can zoom in to regions of interest, and a map history window keeps track of student work so that comparisons are easily made. QUEST is accompanied by a Teacher's Manual to assist teachers in extracting the most information from the available data and tools. Through these efforts we hope to provide teachers and students

  4. A Brief History of Mind and Civilization

    Directory of Open Access Journals (Sweden)

    Garry Jacobs

    2016-05-01

    Full Text Available The rational mind is the highest evolved status of human consciousness. The evolution of mind and civilization has proceeded hand in hand for millennia. The development of new capacities of mind made possible the development of tools, language, agriculture, permanent settlements, towns, cities, religion, trade, transportation, communication, government, law, money, literature and the arts, education, nation states, scientific and technological research. So too, each stage in the development of civilization has shaped the evolution of the human mind and its faculties and the way they are applied in life. The limits to our knowledge and accomplishment reflect limits to our rationality and the utilization of our mental potential. Our knowledge consists of fragmented, piecemeal, compartmentalized theories, when the reality we seek to understand is inclusive, complex and integrated. Our conceptions are based on mechanistic, static, inflexible equilibrium models, whereas the world we live in is alive, dynamic, organic, conscious, responsive, creative and continuously evolving. Our science assumes the poise of an impartial observer of objective reality, whereas all knowledge without exception is colored by the subjective perspective of the observer. Our science strives to be neutral and value-free, whereas the knowledge we need should help us realize universal values. We need to evolve ways of thinking that reunite the objective and subjective dimensions of reality and reflect the integrality, dynamism and vibrancy of evolutionary nature. That is the challenge and adventure before us.

  5. Zora’s Politics: A Brief Introduction

    Directory of Open Access Journals (Sweden)

    Ernest Julius Mitchell II

    2013-09-01

    Full Text Available In his introduction to reading Zora Neale Hurston’s politics, Mitchell argues that contemporary scholarship has misread Hurston in significant ways, distorting Hurston’s work and reputation to serve contesting political agendas; thus, in recent years, she has been associated with “a bewildering array of affiliations: republican, libertarian, radical democrat, reactionary conservative, black cultural nationalist, anti-authoritarian feminist, and woman-hating protofascist.” Recuperating Hurston from this impossible political melee of labels, Mitchell argues, requires a careful reading of Hurston’s work dating from her earliest pieces in the late 1920s, as well as surveying her many yet to be published manuscripts and letters; it requires recognition of the transnational and comparative lens through which she reported on political maneuvers and military histories, as well as reading not only her strong criticisms but also her silences, ironic phrasings, and nuanced critiques in her writings on global colonial enterprises. Mitchell’s introduction to the two Hurston essays here reprinted, “I Saw Negro Votes Peddled” (1950 and “Why the Negro Won’t Buy Communism” (1951—courtesy of the American Legion Magazine—is set in the larger frame of his assertion that Hurston’s work should be read with a deep appreciation of her staunch anticolonialism. Tracing her political philosophy through her views of how race and religion are used to valorize an international culture of violence that serves imperialistic and colonial ends, Mitchell takes his reader on a tour of Hurston’s transnational commentary—from the US occupation of Haiti, to the Spanish and British on the Florida peninsula; from Communist Russia and China, to election practices in the US—to set the stage for our encounters with these rarely read Hurston essays. Reading Mitchell’s “Zora’s Politics: A Brief Introduction” provides a firm foundation for a more

  6. Global Green New Deal. Policy Brief

    International Nuclear Information System (INIS)

    2009-03-01

    The 'Global Green New Deal' (GGND) presented here has three broad objectives. It should make a major contribution to reviving the world economy, saving and creating jobs, and protecting vulnerable groups. It should promote sustainable and inclusive growth and the achievement of the MDGs, especially ending extreme poverty by 2015. Also, it must reduce carbon dependency and ecosystem degradation. These are key risks along a path to a sustainable world economy. Our consultations and our commissioned research, summarized here in this Policy Brief, make a strong case for the active 'greening' of proposed fiscal stimulus packages. However, this must also be backed by necessary changes in international and domestic policy architectures, as the current framework is biased in favour of resurrecting an unsustainable 'brown economy'. Our proposals are therefore grouped under three categories - targeted stimulus spending in 2009-10, changes in domestic policies, and changes in international policy architecture. Furthermore, we recognize that many less developed countries do not have the resources of their own and will have to rely on foreign aid and support, both financial and non-financial. We propose that the fiscal stimulus (to be applied over 2009 and 2010) should prioritize energy efficient buildings and investments in sustainable transport and renewable energy. Developing countries should prioritize investment in agricultural productivity measures, freshwater management, and sanitation, as these have demonstrable and exceptional social returns. Domestic policy reforms are recommended to substantially reduce perverse subsidies (eg: fossil fuels) and instead to create positive incentives and appropriate taxes which will encourage a greener economy. Domestic reforms should also address some common issues in land use and urban policy. Integrated management of freshwater would also require some domestic policy changes, and this should be prioritized by developing countries

    1989-01-01

    An important and substantial area of technical work in which noncontact temperature measurement (NCTM) is desired is that involving combustion process research. In the planning for this workshop, it was hoped that W. Serignano would provide a briefing regarding the experimental requirements for thermal measurements to support such research. The particular features of thermal measurement requirements included those describing the timeline for combustion experiments, the requirements for thermal control and diagnostics of temperature and other related thermal measurements and the criticality to the involved science to parametric features of measurement capability including precision, repeatability, stability, and resolution. In addition, it was hoped that definitions could be provided which characterize the needs for concurrent imaging as it relates to science observations during the conduct of experimentation.

  8. Teaching Physics to Environmental Science Majors Using a Flipped Course Approach

    Science.gov (United States)

    Hill, N. B.; Riha, S. J.; Wysocki, M. W.

    2014-12-01

    Coursework in physics provides a framework for quantitative reasoning and problem solving skill development in budding geoscientists. To make physical concepts more accessible and relevant to students majoring in environmental science, an environmental physics course was developed at Cornell University and offered for the first time during spring 2014. Principles of radiation, thermodynamics, and mechanics were introduced and applied to the atmosphere, hydrosphere, and lithosphere to describe energy and mass transfers in natural and built environments. Environmental physics was designed as a flipped course where students viewed online material outside of class and worked in groups in class to solve sustainability problems. Experiential learning, just-in-time teaching, and peer collaboration strategies were also utilized. In-class problems were drawn from both local and global environmental sustainability concerns. Problems included an investigation of Cornell's lake source cooling system, calculations on the energy consumed in irrigation with groundwater in the southwestern United States, and power generated by wind turbines at various locations around the world. Class attendance was high, with at least 84% of students present at each meeting. Survey results suggest that students enjoyed working in groups and found the in-class problems helpful for assimilating the assigned material. However, some students reported that the workload was too heavy and they preferred traditional lectures to the flipped classroom. The instructors were able to actively engage with students and quickly identify knowledge and skill gaps that needed to be addressed. Overall, the integration of current environmental problems and group work into an introductory physics course could help to inspire and motivate students as they advance their ability to analyze problems quantitatively.

    In this paper I expand on the premises of Jesse Bazzul's thesis in his paper, Neoliberal ideology, global capitalism, and science education: engaging the question of subjectivity, exploring the implications of the ideologies within the culturally emerging logic of science exposes the incommensurability of intents and purposes in its methods and epistemology. I argue that science needs to acknowledge the subjectivity at its core to make space for non-absolute agents and new fields of study.

    2013-05-01

    The science of geo-authentic herbs is a characteristic discipline of traditional Chinese medicine established during thousands of years of clinical practices. It has a long history under the guidance of profound theories of traditional Chinese medicine. The words of "geo-authentic product" were derived from an administrative division unit in the ancient times, which layed stress on the good quality of products in particular regions. In ancient records of traditional Chinese medicine, the words of "geo-authentic product" were first found in Concise Herbal Foundation Compilation of the Ming dynasty, and the words of "geo-authentic herbs" were first discovered in Peony Pavilion of the late Ming dynasty. After all, clinical effect is the fundamental evaluation standard of geo-authentic herbs.

  19. Practice brief. Securing wireless technology for healthcare.

    Retterer, John; Casto, Brian W

    2004-05-01

    Wireless networking can be a very complex science, requiring an understanding of physics and the electromagnetic spectrum. While the radio theory behind the technology can be challenging, a basic understanding of wireless networking can be sufficient for small-scale deployment. Numerous security mechanisms are available to wireless technologies, making it practical, scalable, and affordable for healthcare organizations. The decision on the selected security model should take into account the needs for additional server hardware and administrative costs. Where wide area network connections exist between cooperative organizations, deployment of a distributed security model can be considered to reduce administrative overhead. The wireless approach chosen should be dynamic and concentrate on the organization's specific environmental needs. Aspects of organizational mission, operations, service level, and budget allotment as well as an organization's risk tolerance are all part of the balance in the decision to deploy wireless technology.

    1998-01-01

    NASA has been actively involved in studying the planet Earth and its changing environment for well over thirty years. Within the last decade, NASA's Earth Science Enterprise has become a major observational and scientific element of the U.S. Global Change Research Program. NASA's Earth Science Enterprise management has developed a comprehensive observation-based research program addressing all the critical science questions that will take us into the next century. Furthermore, the entire program is being mapped to answer five Science Themes (1) land-cover and land-use change research (2) seasonal-to-interannual climate variability and prediction (3) natural hazards research and applications (4) long-term climate-natural variability and change research and (5) atmospheric ozone research. Now the emergence of newer technologies on the horizon and at the same time continuously declining budget environment has lead to an effort to refocus the Earth Science Enterprise activities. The intent is not to compromise the overall scientific goals, but rather strengthen them by enabling challenging detection, computational and space flight technologies those have not been practically feasible to date. NASA is planning faster, cost effective and relatively smaller missions to continue the science observations from space for the next decade. At the same time, there is a growing interest in the world in the remote sensing area which will allow NASA to take advantage of this by building strong coalitions with a number of international partners. The focus of this presentation is to provide a comprehensive look at the NASA's Earth Science Enterprise in terms of its brief history, scientific objectives, organization, activities and future direction.

  3. A review of obesity-themed policy briefs.

    Dodson, Elizabeth A; Eyler, Amy A; Chalifour, Stephanie; Wintrode, Christopher G

    2012-09-01

    Policy approaches are one of the most promising population-based means of addressing the epidemic of obesity in the U.S., especially as they create supportive environments for healthy living. Policy briefs can be an effective means of disseminating research information to inform obesity prevention efforts; however, they are often ineffective because of length, density, and inaccessibility. The purposes of this project were to identify a collection of obesity-related policy briefs, analyze the content, and make recommendations for model policy briefs. In 2010, online searching strategies were developed with criteria that included a primary topical focus on obesity, written between 2000 and 2010, targeting any population age group, including a policy-change message, and being readily available online. The research team developed a coding tool and used it to analyze briefs. A subsample of the briefs was used for further analysis on dissemination. Analyses were conducted on 100 briefs. Most (72%) were developed between 2005 and 2010; the average length was five pages. The majority had no tables, few figures, and only 36% included photos. The average reading level was high. A lack of monitoring or evaluating dissemination efforts prevailed. Policy briefs represent an effective, often-preferred, potent tool for public health practitioners and researchers to communicate information to policymakers. Recommendations include presenting information clearly, using a concise format, including design elements, noting reference and contact information, employing active and targeted dissemination efforts, and conducting evaluation.

  4. The early history of ideas on brief interventions for alcohol.

    McCambridge, Jim; Cunningham, John A

    2014-04-01

    This study explores the early development of brief interventions for alcohol using a history of ideas approach with a particular focus on intervention content. The source publications of the key primary studies published from approximately 1962 to 1992 were examined, followed by a brief review of the earliest reviews in this field. These studies were placed in the context of developments in alcohol research and in public health. After early pioneering work on brief interventions, further advances were not made until thinking about alcohol problems and their treatment, most notably on controlled drinking, along with wider changes in public health, created new conditions for progress. There was then a golden era of rapid advance in the late 1980s and early 1990s, when preventing the development of problem drinking became important for public health reasons, in addition to helping already problematic drinkers. Many research challenges identified at that time remain to be met. The content of brief interventions changed over the period of study, although not in ways well informed by research advances, and there were also obvious continuities, with a renewed emphasis on the facilitation of self-change being one important consequence of the development of internet applications. Ideas about brief interventions have changed in important ways. Brief interventions have been studied with different populations of drinkers, with aims embracing both individual and population-level perspectives, and without well-specified contents. The brief intervention field is an appropriate target for further historical investigations, which may help thinking about addressing alcohol and other problems. © 2013 The Authors.

    2005-06-01

    To present a critique of the ideas of Karl Popper, the philosopher of science, whose depiction of psychoanalysis as a pseudoscience is often used to justify attacks on psychoanalysis. Published sources are used to provide a brief intellectual biography of Popper, a summary of his concept of science and a summary of criticisms of Popper's view of science. His depiction of psychoanalysis and Freud's reply are presented. Clinical, experimental and neurobiological research which refutes Popper's view is summarized. There is a vast scholarly published work critical of Popper's falsifiability criterion of science. Less recognized is Popper's misunderstanding and misrepresentation of psychoanalysis; his argument against it is logically flawed and empirically false. Even if Popper's theory of science is accepted, there is considerable clinical, experimental and neurobiological research in psychoanalysis which meets Popper's criterion of science. Attacks on psychoanalysis based on Popper's theory of science are ill-founded and reflect inadequate scholarship.

    The May 2012 Sackler Colloquium on "The Science of Science Communication" brought together scientists with research to communicate and scientists whose research could facilitate that communication. The latter include decision scientists who can identify the scientific results that an audience needs to know, from among all of the scientific results that it would be nice to know; behavioral scientists who can design ways to convey those results and then evaluate the success of those attempts; and social scientists who can create the channels needed for trustworthy communications. This overview offers an introduction to these communication sciences and their roles in science-based communication programs.

    2017-01-01

    OBJECTIVES: Teaching of clinical pathology to medical students has been ignored in many countries such as Iran. We aim to introduce a practical brief course and its proper timing. MATERIALS AND METHODS: Three groups of medical students from consecutive years of entrance passed a 1.5 working day practical course on the field. Their level of knowledge was assessed by pre- and post-tests. Their idea and satisfaction were gathered by questionnaires. RESULTS: Knowledge of students became significantly higher after the course. Their satisfaction was high. Students in later year of education got significantly higher marks. Most of the students wished such a course should be away from basic sciences period and as near as possible to internship. DISCUSSION: Due to overloaded curriculum of general medicine in Iran, we decided to run a brief practical course of laboratory medicine education for medical students. Although the course was practical, the knowledge of students became higher. Students with more clinical experience and knowledge absorbed more. Being actively involved in the classes lit the enthusiasm of students and made them satisfied with the course. It seemed that the course should be placed in later years of clinical training to get the best uptake and results. PMID:29114552

    The present study offers a cross-cultural examination of the effect of prayer on forgiveness. American (n = 51) and Indian (n = 100) participants either prayed for their romantic partner (prayer condition) or described their romantic partner's physical attributes (control condition). Prayers were self-guided and lasted 3 minutes. Pre-test and post-test measures of retaliation were completed. Results showed that participants in the prayer group showed statistically significant decreases in retaliation motives from pre-test to post-test and the magnitude of this change was not different across cultures. Control groups in both cultures showed no change. Because of the religious diversity present in the Indian sample, the robustness of the effect of prayer on forgiveness was tested across Christian, Hindu and Muslim Indians. Religious affiliation did not moderate the effect of prayer on forgiveness in this sample. Results suggest that a brief prayer is capable of producing real change in forgiveness and this change is consistent across American and Indian cultures and across three different religious groups in India. Brief prayer for others that enhances forgiveness may be useful for individuals in close relationships, in certain counselling settings and for people in many different walks of life. © 2015 International Union of Psychological Science.

  15. Sapiens a brief history of humankind

    2015-01-01

    From a renowned historian comes a groundbreaking narrative of humanity’s creation and evolution—a #1 international bestseller—that explores the ways in which biology and history have defined us and enhanced our understanding of what it means to be “human.” One hundred thousand years ago, at least six different species of humans inhabited Earth. Yet today there is only one—homo sapiens. What happened to the others? And what may happen to us? Most books about the history of humanity pursue either a historical or a biological approach, but Dr. Yuval Noah Harari breaks the mold with this highly original book that begins about 70,000 years ago with the appearance of modern cognition. From examining the role evolving humans have played in the global ecosystem to charting the rise of empires, Sapiens integrates history and science to reconsider accepted narratives, connect past developments with contemporary concerns, and examine specific events within the context of larger ideas.

    2016-06-01

    Reading the interesting article Discerning selective traditions in science education by Per Sund , which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.

    Sleep disturbances are common among adolescents, but there are no brief interventions to treat them. The objective of this study was to evaluate the effectiveness of a brief semistructured, individually delivered sleep intervention to ameliorate adolescents' sleeping difficulties and lengthen sleep duration. All students aged 16-18 years in a high school were screened for sleeping difficulties and 36 students with the highest sleep problem scores were invited to the intervention. Postintervention improvements were observed on self-reported and actiwatch-registered sleep duration, self-reported sleep quality and sleep latency, perceived stress and anxiety (all p values sleep efficiency and sleep latency did not change (p > 0.05). A brief individual sleep intervention can be effective in lengthening sleep duration and improving subjective sleep quality and well-being among adolescents.

    Over the last years deep learning methods have been shown to outperform previous state-of-the-art machine learning techniques in several fields, with computer vision being one of the most prominent cases. This review paper provides a brief overview of some of the most significant deep learning schemes used in computer vision problems, that is, Convolutional Neural Networks, Deep Boltzmann Machines and Deep Belief Networks, and Stacked Denoising Autoencoders. A brief account of their history, structure, advantages, and limitations is given, followed by a description of their applications in various computer vision tasks, such as object detection, face recognition, action and activity recognition, and human pose estimation. Finally, a brief overview is given of future directions in designing deep learning schemes for computer vision problems and the challenges involved therein.
