    1989-07-01

    The first of two tapes of the Galileo Mission Science press briefing is presented. The panel is moderated by George Diller from the Kennedy Space Center (KSC) Public Affairs Office. The participants are John Conway, the director of Payload and operations at Kennedy; Donald E. Williams, Commander of STS-43, the shuttle mission which will launch the Galileo mission; John Casani, the Deputy Assistant Director of Flight Projects at the Jet Propulsion Lab (JPL); Dick Spehalski, Galileo Project Manager at JPL; and Terrence Johnson, Galileo Project Scientist at JPL. The briefing begins with an announcement of the arrival of the Galileo Orbiter at KSC. The required steps prior to the launch are discussed. The mission trajectory and gravity assists from planetary and solar flybys are reviewed. Detailed designs of the orbiter are shown. The distance that Galileo will travel from the sun precludes the use of solar energy for heat. Therefore Radioisotope heater units are used to keep the equipment at operational temperature. A video of the arrival of the spacecraft at KSC and final tests and preparations is shown. Some of the many science goals of the mission are reviewed. Another video showing an overview of the Galileo mission is presented. During the question and answer period, the issue of the use of plutonium on the mission is broached, which engenders a review of the testing methods used to ensure the safety of the capsules containing the hazardous substance. This video has actual shots of the orbiter, as it is undergoing the final preparations and tests for the mission.

    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.

    2016-04-01

    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.

  6. A Brief Philosophical Encounter with Science and Medicine

    Directory of Open Access Journals (Sweden)

    Amir Ehsan Karbasizadeh

    2013-01-01

    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.

    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.

  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

    “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.

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

    2009-11-01

    Full Text Available Comics are a popular art form especially among children and as such provide a potential medium for science education and communication. In an attempt to present science comics in a museum exhibit I found many science themed comics and graphic books. Here I attempt to provide an overview of already available comics that communicate science, the genre of ‘science comics’. I also provide a quick literature review for evidence that comics can indeed be efficiently used for promoting scientific literacy via education and communication. I address the issue of lack of studies about science comics and their readers and suggest some possible reasons for this as well as some questions that could be addressed in future studies on the effect these comics may have on science communication.

    2006-12-01

    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.

    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.

  13. Good science, deceptive science, and fraud, plus a brief discussion of peer review

    Science.gov (United States)

    Lundquist, Marjorie

    2011-03-01

    What makes scientific publication different from other types of publication? Traditionally, it was that scientists published not only their conclusions, but also their data (which enabled others wanting to re-evaluate the data to do so). Publishing their data helped keep scientists honest. In the mid-20th century the policies of scientific journals changed, partly because very large data sets were being evaluated via computer. Many (but not all) scientific journals paid homage to scientific tradition by establishing archives for data serving as the basis for published scientific papers, while only a description of the study and the conclusions were published in the peer-reviewed scientific journals. This set the stage for scientific deception and scientific fraud, which became widespread in certain fields of study during the latter part of the 20th century. Indeed, some organizations were established that appeared to be legitimate scientific societies, but in fact existed for the purpose of promoting the incorrect evaluation of scientific data and publishing deceptive studies masquerading as sound scientific studies. The field of medicine has also become more science than art, with its current emphasis on ``evidence-based medicine.'' The different types of scientific deceit/fraud are identified, and a lifetime of experience with the correction of scientific error, plus encounters with scientific deception and scientific fraud, is summarized.

    In the context of new realities, perceptions, and concerns, it is fitting that the government has undertaken this Science and Technology Review, questioning not only how much to spend but also the justification and the best ways to carry out federally-funded research. We share the government's concern about the lack of economic competitiveness of our industries and agree that government-sponsored research should make a bigger contribution to the nation's global economic position. The CSCI, which represents the clinical investigators/scientists in this country, is grateful for having been given the opportunity to make this "tour d'horizon" of Canadian clinical research. In this brief, we have attempted to articulate the needs for, and the benefits of, basic biomedical research because it is the only type of research which will provide us with final answers. However, it should be more closely articulated with applied research, as well as with epidemiological, evaluative, and operational approaches which have been neglected. This brief has emphasized that CSCI is committed to PUTTING MORE SCIENCE INTO MEDICINE by encouraging a greater flow of discoveries from the laboratory research bench to the bedside and the community. We made the point that there is a crisis in patient-oriented research and a decrease of young physicians opting for research careers. The Royal College of Physicians and Surgeons of Canada and the MRC are responsive to this situation, which may compromise our capacity to discharge our broader mission. The MRC has given itself valid instruments to foster the creation of wealth through special programs such as the NCE, the University/Industry program, and the MRC-PMAC partnership. Some refining is in order, and close scrutiny of outcome is essential. Both the academic community and industry have their share of responsibility for the less-than-optimal transfer of knowledge to the market place. Lack of venture capital is also a serious issue.

    The completed full-scale Cornell cold neutron source, an integral component of the Cornell cold neutron beam facility, has undergone testing prior to its insertion (and consequent activation) in the Cornell 500-kW TRIGA reactor. The source consists of an organic moderator (mesitylene) contained within an aluminum chamber, which is cooled by conduction through a 99.999+ pure 1.90-cm-diam copper rod 267 cm long, coupled to the second (4-W capacity), cooler stage of a helium cryorefrigerator. Approximately 18 h is required to achieve equilibrium chamber temperatures. To lower the radiational T 4 load on the second stage, the chamber and rod are surrounded by an active heat shield, consisting of 99.99+ pure copper (oxygen-free high conductivity) coupled to the first 60-W capacity stage of the cryorefrigerator. Other components include the associated mesitylene handling system (MHS) and vacuum system.

  4. 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).

    Managing parallel cryogenic flows has become a key challenge in designing efficient and smart cryo-modules for particle accelerators. In analysing the heating dynamics of the Cornell high current injector module a computational tool has been set-up allowing time resolved analysis and optimization. We describe the computational methods and data sets we have used, report the results and compare them to measured data from the module being in good agreement. Mitigation strategies developed on basis of this model have helped us in pushing the operational limitations.

  11. A brief history of geospatial science in the Department of Energy

    Energy Technology Data Exchange (ETDEWEB)

    Bhaduri, Budhendra L [ORNL

    2007-01-01

    The U.S. Department of Energy (DOE) has a rich history of significant contributions to geospatial science spanning the past four decades. In the early years, work focused on basic research, such as development of algorithms for processing geographic data and early use of LANDSAT imagery. The emphasis shifted in the mid-1970s to development of geographic information system (GIS) applications to support programs such as the National Uranium Resource Evaluation (NURE), and later to issue-oriented GIS applications supporting programs such as environmental restoration and management (mid-1980s through present). Throughout this period, the DOE national laboratories represented a strong chorus of voices advocating the importance of geospatial science and technology in the decades to come. The establishment of a Geospatial Science Program by the DOE Office of the Chief Information Officer in 2005 reflects the continued potential of geospatial science to enhance DOE's science, projects, and operations, as is well demonstrated by historical analysis.

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

    Directory of Open Access Journals (Sweden)

    Adam Bartnik

    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.

    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.

Included are the use of complex numbers and complex functions in the description and analysis of chaos and fractals with the aid of modern computer technology. In addition, the phasor method is described with examples of applications in engineering science. The major focus of this paper is to provide basic information through historical approach to mathematics teaching and learning of the fundamental knowledge and skills required for students and teachers at all levels so that they can understand the concepts of mathematics, and mathematics education in science and technology.

  15. 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.

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

    Recent health care legislation and shifting health care financing strategies are transforming health and behavioral health (a broad term referring to mental health, substance use, and health behavior) care in the United States. Advances in knowledge regarding effective treatment and services coupled with incentives for innovation in health and behavioral health care delivery systems make this a unique time for mobilizing our science to enhance the success of health and behavioral health care redesign. To optimize the potential of our current health care environment, a team was formed composed of leaders from the Societies of Clinical Child & Adolescent Psychology, Pediatric Psychology, and Child and Family Policy and Practice (Divisions 53, 54, and 37 of the American Psychological Association). This team was charged with reviewing the scientific and policy literature with a focus on five major issues: (a) improving access to care and reducing health disparities, (b) integrating behavioral health care within primary care, (c) preventive services, (d) enhancing quality and outcomes of care, and (e) training and workforce development. The products of that work are summarized here, including recommendations for future research, clinical, training, and policy directions. We conclude that the current emphasis on accountable care and evaluation of the outcomes of care offer numerous opportunities for psychologists to integrate science and practice for the benefit of our children, families, and nation. The dramatic changes that are occurring in psychological and behavioral health care services and payment systems also require evolution in our practice and training models. PMID:26430948

    1998-06-01

    A device to moderate reactor spectrum neutrons to subthermal energies and filter out photons and higher energy neutrons has been designed, constructed and tested at Ward Laboratory, Cornell University. The Cornell Cold Neutron Source, which houses a chamber containing an organic moderator (mesitylene), the cryogenic cooling apparatus, and the first three one-meter long neutron guide elements, is physically inserted into a beamport in the reactor biological shield. The remaining 10 guide elements, which act as the filter, are mounted on a horizontal I-beam, and surrounded with suitable radiation shielding. The elements are horizontally displaced from the beamport axis in a combination curved/straight layout to eliminate directly transmitted radiation. The guide penetrates the reactor bay wall, terminating in a dedicated room to provide a location for low background experiments. Out-of-reactor bench thermal tests were conducted on the cryorefrigerator itself, then on a shortened version of the cryogenic cooling apparatus, and finally on the full scale system using heaters to simulate reactor induced nuclear heating in upstream cryogenic components. Temperature results, measured by silicon diodes, were close to predicted values. In-reactor tests were conducted to benchmark thermal performance, and to ascertain reliability of temperature and flux measurement systems. Type E thermocouples were selected for temperature measurement in the hostile reactor environment; although they depart from standard output at cryogenic temperatures due to inhomogeneities in the wire, crucial thermocouples located on the moderator chamber are calibrated against the in situ gas thermometer formed with the chamber as the sense bulb and a canister of known volume as the gas reservoir. In- reactor trials demonstrated reproducibility of thermocouple results. Moderator temperatures of 11 K at zero reactor power up to 28.5 K at 500 kW were obtained. Time-of-flight measurements were taken at 10

  8. Georges Lemaître: A Brief Introduction to His Science, His Theology, and His Impact

    Science.gov (United States)

    Holder, Rodney D.; Mitton, Simon

    For several decades historians of astronomy have overlooked the achievements in cosmology of the Belgian priest and professor of physics, Georges Lemaître (1894-1966). In 1927 he became the first to propose a theory of the expansion of the universe to explain the redshifts of galaxies, an advance that is often attributed to Edwin Hubble. Lemaître published the original version of the Hubble Law, and he produced the first estimate of the Hubble constant. He proposed a "Fireworks Universe" that became better known as the Big Bang theory for the origin of the universe, for which he is now popularly regarded as the "father of the Big Bang." This Introduction gives an overview to the 13 chapters in this book, which is devoted to the science and theology of a remarkable scholar, cosmologist, and theologian.

    Since the initial Swiss heroin-assisted treatment (HAT) study conducted in the mid-1990s, several other jurisdictions in Europe and North America have implemented HAT trials. All of these studies embrace the same goal-investigating the utility of medical heroin prescribing for problematic opioid users-yet are distinct in various key details. This paper briefly reviews (initiated or completed) studies and their main parameters, including primary research objectives, design, target populations, outcome measures, current status and-where available-key results. We conclude this overview with some final observations on a decade of intensive HAT research in the jurisdictions examined, including the suggestion that there is a mounting onus on the realm of politics to translate the-largely positive-data from completed HAT science into corresponding policy and programming in order to expand effective treatment options for the high-risk population of illicit opioid users.

  10. 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

    2017-06-01

    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.

    I summarize my research studying details of the emission line profiles of the mid infrared [NeII] 12.8 microns and [NeIII] 15.6 microns emission lines. Observations are from the Spitzer Infrared Spectrograph (IRS) (Houck et al. 2004), so I illustrate use of the archive of these spectra. The IRS team developed the Cornell Atlas of Spitzer IRS Sources (CASSIS) found at cassis.sirtf.com. At present, all low resolution (Lebouteiller et al. 2011) and high resolution (Lebouteiller et al. 2015) staring observations with the IRS are available (more than 20,000 spectra of about 15,000 distinct sources). Spectra are provided in various formats to enable easy viewing or measurements. Spectra cover 5 microns to 37 microns in low resolution (R ˜ 60 to 125) and 10 microns to 37 microns in high resolution (R ˜ 600) modes. CASSIS is intended as a long term resource for the astronomical community so that this fundamental data base of mid-infrared spectra will be easily usable perpetually, and I demonstrate some examples of its use.

  14. High Brightness, High Average Current Injector Development at Cornell

    CERN Document Server

    Sinclair, C K

    2005-01-01

    Cornell University is constructing a 100 mA average current, high brightness electron injector for a planned Energy Recovery Linac (ERL) hard X-ray synchrotron radiation source. This injector will employ a very high voltage DC gun with a negative electron affinity photoemission cathode. Relatively long duration electron pulses from the photocathode will be drift bunched, and accelerated to 5-15 MeV with five two-cell, 1300 MHz superconducting cavities. The total beam power will be limited to 575 kW by the DC and RF power sources. A genetic algorithm based computational optimization of this injector has resulted in simulated rms normalized emittances of 0.1 mm-mrad at 80 pC/bunch, and 0.7 mm-mrad at 1 nC/bunch. The many technical issues and their design solutions will be discussed. Construction of the gun and the SRF cavities is well underway. The schedule for completion, and the planned measurements, will be presented.

    2013-01-01

    In 2008 the Cornell Electron/Positron Storage Ring (CESR) was reconfigured from an electron/positron collider to serve as a testbed for the International Linear Collider (ILC) damping rings. One of the primary goals of the CESR Test Accelerator (CesrTA) project is to develop low emittance tuning techniques to achieve sub-10pm geometric vertical emittance at 2.085 GeV. This paper discusses the tuning methods used at CesrTA to achieve low-emittance conditions. A minimum vertical emittance of 8.7 +2.9/-3.4(sys) +/-0.2(stat) pm has been achieved at 2.085 GeV. In various configurations and beam energies the correction technique routinely achieves vertical emittance <15 pm after correction. Beam-based measurement and correction requires about 15 minutes. Simulations modeling the effects of magnet misalignments, BPM errors, and emittance correction algorithm suggest the residual vertical emittance measured at the conclusion of the tuning procedure is dominated by sources other than optics errors and misalignments...

    2015-01-01

    The Cornell-BNL FFAG-ERL Test Accelerator (C$\\beta$) will comprise the first ever Energy Recovery Linac (ERL) based on a Fixed Field Alternating Gradient (FFAG) lattice. In particular, we plan to use a Non Scaling FFAG (NS-FFAG) lattice that is very compact and thus space- and cost- effective, enabling multiple passes of the electron beam in a single recirculation beam line, using the superconducting RF (SRF) linac multiple times. The FFAG-ERL moves the cost optimized linac and recirculation lattice to a dramatically better optimum. The prime accelerator science motivation for C$\\beta$ is proving that the FFAG-ERL concept works. This is an important milestone for the Brookhaven National Laboratory (BNL) plans to build a major Nuclear Physics facility, eRHIC, based on producing 21 GeV electron beams to collide with the RHIC ion beams. A consequence of the C$\\beta$ work would be the availability of significantly better, cost-effective, compact CW high-brightness electron beams for a plethora of scientific inves...

  18. 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).

    Objective:To analyze the assessment value of ECG Cornell voltage for left ventricle hypertrophy in essential hypertension patients and its correlation with cardiovascular events. Methods:A total of 118 cases of patients with essential hypertension who received inpatients treatment in our hospital from March 2013 to March 2015 were selected as the research subjects. According to ECG baseline, all included patients were divided into Cornell voltage increase group (increase ≥25%) 47 cases, no Cornell voltage change group (change < 25%) 36 cases and Cornell voltage decrease group (decrease ≥25%) 35 cases. Ultrasonic left heart indexes and serum indexes of three groups were compared, and the correlation between Cornell voltage and cardiovascular events was further analyzed.Results: Ultrasonic LVEDD, LVMI, IVSd, PWd and RWT values as well as serum uric acid, IMD, CysC, FGF23 and Hcy values of Cornell voltage decrease group were lower than those of no Cornell voltage change group and Cornell voltage increase group; ECG Cornell voltage levels in patients with essential hypertension were positively correlated with the incidence rate of cardiovascular events such as acute coronary events, sudden cardiac death and acute stroke.Conclusion: ECG Cornell voltage index can better identify the degree of left ventricle hypertrophy in patients with essential hypertension, and can be used as an independent predictor of cardiovascular events.

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

    Left ventricular hypertrophy (LVH) is an independent risk factor for cardiovascular disease and is associated with heart failure development. The Cornell product is an easily measured electrocardiographic parameter for assessing LVH. However, it is undetermined whether the Cornell product can predict the cardiac prognosis of chronic heart failure (CHF) patients. We performed standard 12-lead electrocardiography and calculated the Cornell product in 432 consecutive CHF patients. LV geometry was assessed as normal, concentric remodeling, concentric or eccentric hypertrophy. The Cornell product was significantly higher in patients with eccentric hypertrophy, and increased with advancing New York Heart Association functional class. During a median follow-up of 660 days, there were 121 cardiac events including 36 cardiac deaths and 85 re-hospitalizations for worsening heart failure. Multivariate Cox proportional hazard analysis showed that the Cornell product was an independent predictor of cardiac events in CHF patients. Patients in the highest quartile of Cornell product had a higher prevalence of LV eccentric hypertrophy (22, 29, 33 and 67 % for quartiles one through four). Kaplan-Meier analysis demonstrated that the highest quartile of Cornell product was associated with the greatest risk among CHF patients. The Cornell product is associated with LV eccentric hypertrophy and can be used to predict future cardiac events in CHF patients.

  4. Trading twitter: Amateur recorders and economies of scientific exchange at the Cornell Library of Natural Sounds.

    Bruyninckx, Joeri

    2015-06-01

    Scientists have long engaged in collaborations with field collectors, but how are such collaborations established and maintained? This article examines structures of collaborative data collection between professional scientists and various field recorders around the Cornell Library of Natural Sounds. The Library collects animal sound recordings for use in education, preservation, and entertainment, but primarily in the scientific field of bio-acoustics. Since 1945, the Library has enlisted academic researchers, commercial recorders and broadcasters (such as the British Broadcasting Corporation), and amateur sound hunters in its expansion. I argue that the Cornell Library of Natural Sounds managed to craft and sustain a crucial network of contributors through creative and strategic brokering with its collection of recordings/data. Drawing on notions from exchange theory, I show that sound recordings were valued not just as scientific data, but also as copyrighted commodities that could be bought, sold, traded, and converted in a range of economic, social, and symbolic capitals within collaborators' respective social fields. Thus, aligning collaborators' interests, these exchange relations enabled the Cornell Library of Natural Sounds to negotiate amateur recorders' reliability, willingness to share work, and commitment to scientific standards, as well as the bonds that solidified their collaboration with the Cornell Library of Natural Sounds. Attending to the micro-economics of data exchange, this article thus brings into perspective the multi-dimensional processes through which data-flows are managed.

    Using the variational method and supersymmetric quantum mechanics we calculated, in an approximate way, the eigenvalues, eigenfunctions and wave functions at the origin of the Cornell potential. We compared results with numerical solutions for heavy quarkonia $c \\bar {c}, b \\bar{b}$ and $b \\bar{c}$.

    The equation of state (EOS) of quark-gluon plasma (QGP) using the Cornell potential based on Mayer's cluster expansion is presented. The string constant and the strong coupling constant for QGP are calculated. The EOS developed could describe the lattice EOS for pure gauge, two-flavor and three-flavor QGP qualitatively.

    An analytical solution of the Dirac equation with a Cornell potential, with identical scalar and vectorial parts, is presented. The solution is obtained by using the linear potential solution, related to Airy functions, multiplied by another function to be determined. The energy levels are obtained and we notice that they obey a band structure.

  15. Ecological Theory Origin from Natural to Social Science of Vice Versa? A Brief Conceptual History for Social Work

    Directory of Open Access Journals (Sweden)

    Karen Smith Rotabi

    2007-05-01

    Full Text Available The origin of holistic social work and ecological theory was investigated. Emphasis was placed on Howard W. Odum, founding dean of the University of North Carolina School of Public Welfare, and subsequent scholarship by his sons, collaborators on the first American ecology text. Eugene and Howard Thomas Odum, internationally recognized ecological scholars, identified holism as a universal concept originating in social sciences, crediting their father’s earlier sociological work,which later bridged to ecosystems ecology. A historical review of the influential sociologists, social workers, and ecologists is presented to build the case for ecological theory transfer across the three disciplines, beginning with sociology. Critique of the current use of the ecological perspective is discussed, specifically social work’s tendency to target social systems and behavior while largely ignoring the natural environment.

    The Cornell Cold Neutron Beam Facility consists of two major subsystems, a cold neutron source (CNS) and a 13-m-long curved neutron guide. This paper describes the initial in-reactor performance tests of the CNS. The results agree closely with predictions from out-of-reactor tests and meet the design criteria for safety and simplicity of operation. This phase of the project has therefore been completed. Three meters of neutron guide were in place during these tests, and a preliminary evaluation of neutronic properties is also presented.

    The Cornell Astronomical Society is an undergraduate student-run organization that operates Cornell’s on-campus Fuertes Observatory with the help of members of the astronomy department and local amateur astronomy volunteers. While some of our members study physics or astronomy, the majority of our club members represent a diverse spectrum of majors both inside and outside of other STEM fields. Our primary activity as a club is to host weekly public stargazing nights that are attended annually by over two thousand people in a city of Ithaca that has a population of only one hundred thousand. We train our members to use a variety of telescopes and to open and close the observatory with the ultimate goal of having any one of us able to operate Fuertes individually. We also teach stargazing-related astronomy knowledge and host a weekly public lecture series, in which CAS members give talks on basic, but interesting topics in astronomy. Our club effort has made Fuertes Observatory a true part of the Cornell experience.

    1995-07-01

    This paper introduces and describes the new Cornell Beam Research Accelerator, COBRA, the result of a three and one-half year collaboration. The flexible 4 to 5-MV, 100 to 250-kA, 46-ns pulse width accelerator is based on a four-cavity Inductive Voltage Adder (IVA) design. In addition to being a mix of new and existing components, COBRA is unique in the sense that each cavity is driven by a single pulse forming line, and the IVA output polarity may be reversed by rotating the cavities 1800 about their vertical axis. Our tests with negative high voltage on the inner MITL stalk indicate that the vacuum power flow has established reasonable azimuthal symmetry within about 2 ns (or 0.6 m) after the cavity output cap. Preliminary results with the accelerator, single cavity, and MITL are presented alone, with the design details and circuit model predictions.

    1989-10-01

    Cryostats intended for very low temperature use must meet very stringent demands in the areas of vibrational isolation, electrical isolation, and reliable thermometry. The efforts which have been made in these areas during the construction of the new microkelvin cryostat at Cornell have met with varying success. In this paper will be described both a number of our ideas which we feel have worked well (features, in the jargon of the American advertising industry), some which seemed like good ideas at the time, but which should not be repeated elsewhere (non-features, by logical extension). Also corrections to some of the less successful approaches will be discussed, which have lead to the production of some ex-non-features.

    2013-01-01

    Full Text Available The Klein-Gordon (KG equation for the two-dimensional scalar-vector harmonic oscillator plus Cornell potentials in the presence of external magnetic and Aharonov-Bohm (AB flux fields is solved using the wave function ansatz method. The exact energy eigenvalues and the wave functions are obtained in terms of potential parameters, magnetic field strength, AB flux field, and magnetic quantum number. The results obtained by using different Larmor frequencies are compared with the results in the absence of both magnetic field (ωL = 0 and AB flux field (ξ=0 cases. Effect of external fields on the nonrelativistic energy eigenvalues and wave function solutions is also precisely presented. Some special cases like harmonic oscillator and Coulombic fields are also studied.

  1. Noncommutative correction to the Cornell potential in heavy-quarkonium atoms

    Mirjalili, A.; Taki, M.

    2016-02-01

    We investigate the effect of space-time noncommutativity on the Cornell potential in heavy-quarkonium systems. It is known that the space-time noncommutativity can create bound states, and we therefore consider the noncommutative geometry of the space-time as a correction in quarkonium models. Furthermore, we take the experimental hyperfine measurements of the bottomium ground state as an upper limit on the noncommutative energy correction and derive the maximum possible value of the noncommutative parameter θ, obtaining θ ≤ 37.94 · 10-34 m2. Finally, we use our model to calculate the maximum value of the noncommutative energy correction for energy levels of charmonium and bottomium in 1S and 2S levels. The energy correction as a binding effect in quarkonium system is smaller for charmonium than for bottomium, as expected.

    2006-01-01

    Cornell, California Institute of Technology (Caltech), and Jet Propulsion Lab (JPL) have joined together to study development of a 25 meter sub-millimeter telescope (CCAT) on a high peak in the Atacama region of northern Chile, where the atmosphere is so dry as to permit observation at wavelengths as short as 200 micron. The telescope is designed to deliver high efficiency images at that wavelength with a total 1/2 wavefront error of about 10 microns. With a 20 arc min field of view, CCAT will be able to accommodate large format bolometer arrays and will excel at carrying out surveys as well as resolving structures to the 2 arc sec. resolution level. The telescope will be an ideal complement to ALMA. Initial instrumentation will include both a wide field bolometer camera and a medium resolution spectrograph. Studies of the major telescope subsystems have been performed as part of an initial Feasibility Concept Study. Novel aspects of the telescope design include kinematic mounting and active positioning of pr...

    Aim. The aim of the present study was to investigate the effect of cornel iridoid glycoside (CIG) on tau hyperphosphorylation induced by wortmannin (WT) and GF-109203X (GFX) and the underlying mechanisms. Methods. Human neuroblastoma SK-N-SH cells were preincubated with CIG (50, 100, and 200 µg/ml, resp.) for 24 h and then exposed to 10 µM WT and 10 µM GFX for 3 h after washing out CIG. Immunohistochemistry was used to observe the microtubular cytoskeleton of the cultured cells. Western blotting was used to measure the phosphorylation level of tau protein, glycogen synthase kinase 3 β (GSK-3 β ), and protein phosphatase 2A (PP2A). The activity of PP2A was detected by a biochemical assay. Results. Preincubation of CIG significantly attenuated the WT/GFX-induced tau hyperphosphorylation at the sites of Thr205, Thr212, Ser214, Thr217, Ser396, and PHF-1 and improved the damage of morphology and microtubular cytoskeleton of the cells. CIG did not prevent the decrease in p-AKT-ser473 and p-GSK-3 β -ser9 induced by WT/GFX. However, CIG significantly elevated the activity of PP2A by reducing the demethylation of PP2A catalytic subunit (PP2Ac) at Leu309 and the ratio of PME-1/LCMT in the WT/GFX-treated cells. The results suggest that CIG may be beneficial to the treatment of AD.

    The purpose of the present study was to investigate the effects of cornel iridoid glycoside (CIG) on the activity of cholinesterases in vitro, and to investigate the mechanism of CIG's treating Alzheimer's disease (AD). The sources of cholinesterases were prepared from human blood cells, rat brain homogenate and human blood plasma, respectively. The biochemical methods were used to detect the activity of acetylcholine esterase (AChE) and butyryl cholinesterase (BuChE) to investigate the influence of CIG on cholinesterases. The results showed that CIG inhibited the activity of AChE of human blood cells and rat brain homogenate, with the 50% inhibition rate (IC50) of 1.6 g . L-1 and 3.3 g . L-1, respectively; and the inhibition of AChE of CIG is reversible. CIG also inhibited the activity of BuChE of human blood plasma, with the IC50 of 2.9 g . L-1. In conclusion, CIG can inhibit the activity of AChE and BuChE in vitro, which may be one of the mechanisms of CIG to treat AD.

    Full Text Available Purpose. This study was to investigate the effects of cornel iridoid glycoside (CIG on spinal cord injury (SCI in rats. Methods. The thoracic cord (at T9 of rats was injured by clip compression for 30 sec. Locomotor function was assessed using the Basso, Beattie, and Bresnahan (BBB rating scale. Neuroanatomic stereological parameters as well as Nogo-A, p75 neurotrophin receptor (p75NTR, and ROCKII expression were measured by histological processing, immunohistochemistry, and stereological analyses. The axons passing through the lesion site were detected by BDA tracing. Results. Intragastric administration of CIG (60 and 180 mg/kg improved the locomotor impairment at 10, 17, 24, and 31 days post-injury (dpi compared with untreated SCI model rats. CIG treatment decreased the volume of the lesion epicenter (LEp and increased the volume of spared tissue and the number of surviving neurons in the injured spinal cord at 31 dpi. CIG promoted the growth of BDA-positive axons and their passage through the lesion site and decreased the expression of Nogo-A, p75NTR, and ROCKII both in and around the LEp. Conclusion. CIG improved the locomotor impairment, decreased tissue damage, and downregulated the myelin-associated inhibition signaling pathway in SCI rats. The results suggest that CIG may be beneficial for SCI therapy.

    2013-01-01

    In storage rings, horizontal dispersion in the rf cavities introduces horizontal-longitudinal ($xz$) coupling, contributing to beam tilt in the $xz$ plane. This coupling can be characterized by a "crabbing" dispersion term $\\zeta_a$ that comes from decomposing the $1$-turn transfer matrix. $\\zeta_a$ is proportional to the rf cavity voltage and the horizontal dispersion in the cavity. We report experiments at the Cornell Electron Storage Ring Test Accelerator (CesrTA) where $xz$ coupling was explored using three lattices with distinct crabbing properties. We characterize the $xz$ coupling for each case by measuring the horizontal projection of the beam with a beam size monitor. The three lattice configurations correspond to a) $16$ mrad $xz$ tilt at the beam size monitor source point, b) compensation of the $\\zeta_a$ introduced by one of two pairs of RF cavities with the second, and c) zero dispersion in RF cavities, eliminating $\\zeta_a$ entirely. Additionally, intrabeam scattering (IBS) is evident in our mea...

    Eichhorn, R.; Holmes, A.; Markham, S.; Sabol, D.; Smith, E.

    2014-01-01

    The proposed Cornell Energy Recovery Linac (ERL) is based on superconducting 1.3 GHz cavities operated in continuous wave mode. It presents a number of interesting cryogenic challenges, as approximately 30 cryomodules share a common vacuum space and common cryogenic distribution lines forming two 300 meter long half-linacs. Within each module, are a number of concentrated heat loads which must be intercepted at 80K and 6.5K. It is necessary to provide convective cooling by helium gas via many parallel channels to intercept these large individual loads (average up to 200W at 80K, but some as high as 400W), and we discuss the design choices made to ensure no flow instabilities. We limit the control complexity by using a single control valve for each coolant stream within each cryomodule. These streams are subdivided into parallel paths using a length of smaller diameter tubing in the cold part to limit the variation in mass flow with heat load for each path. A model describing these flows at 80 K and 5 K under different operation regimes will be derived and presented and parameters for stability will be discussed.

    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.

    OBJECTIVE To compare vocational aspirations and outcomes of participants in the 10-week Leadership Program for Veterinary Students at Cornell University. DESIGN Survey. SAMPLE Veterinary students who participated in the program between 1990 and 2013. PROCEDURES Questionnaires that sought information about the career aspirations of participants at the beginning and end of the program were reviewed, along with records documenting the career progression of participants, audio recordings of interviews conducted with students, and notes of vocation-oriented counseling sessions held during each year’s program. RESULTS At the conclusion of the program, 143 of 174 (82%) participants indicated they were more likely than not to undertake research training after completing their veterinary degree, compared with 106 of 174 (61%) at the beginning. Participation also stimulated interest in residency training and industry, but did little to promote interest in careers in government or the military. The percentage of participants who indicated they were more likely than not to pursue additional training in private practice decreased from 97 of 174 (56%) at the beginning of the program to 75 of 174 (43%) at the end. Information on career progression was available for 391 individuals, of whom 177 (45%) were pursuing careers of the kind envisioned by the program. However, 189 (48%) participants had a career in general or specialty clinical practice. CONCLUSIONS AND CLINICAL RELEVANCE The Leadership Program appeared to have a short-term influence on careers anticipated by program participants. However, a substantial proportion pursued careers in clinical practice after graduation. PMID:27654162

    2014-11-01

    Full Text Available Significant progress has been made in the last decade in the development of optogenetic effectors and sensors that can be deployed to understand complex biological signaling in mammals at a molecular level, without disrupting the distributed, lineage specific signaling circuits that comprise nuanced physiological responses. A major barrier to the widespread exploitation of these imaging tools, however, is the lack of readily available genetic reagents that can be easily combined to probe complex biological processes. Ideally, one could envision purpose –produced mouse lines expressing optically compatible sensors and effectors, sensor pairs in distinct lineages, or sensor pairs in discrete subcellular compartments, such that they could be crossed to enable in vivo imaging studies of unprecedented scientific power. Such lines could also be combined with mice to determine the alteration in signaling accompanying targeted gene deletion or addition. In order to address this lack, the National Heart Lung and Blood Institute has recently funded an optogenetic resource designed to create optically compatible, combinatorial mouse lines that will advance NHLBI research. Here we review recent advances in optogenetic sensor and effectors and describe the rationale and goals for the establishment of the Cornell/National Heart Lung Blood Resource for Optogenetic Mice (CHROMus.

    2015-01-01

    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 CW 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 CW 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...

    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.

    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.

  19. Facilitating the initiation of the physician's professional identity: Cornell's urban semester program.

    2014-12-01

    Calling for major reform in medical education, the Carnegie Institute report 'Educating Physicians' espoused the importance of assisting student trainees in forming their professional identities. Here, we consider the question: At what educational stage should future physicians begin this process? The literature suggests that the process begins when students matriculate in medical school; we posit, however, that premedical students can begin their proto-professional development as college undergraduates. We describe here the pedagogy of Cornell University's urban semester program (USP), which enables college students to participate in shadowing experiences as part of an integrated structured study programme. USP students report improved communicative competency, changes in their perceptions and attitudes toward medical practice, and powerful influences on their personal and professional development upon completion of the programme. We suggest the solution to the question of 'When and under what conditions should shadowing take place?' is to utilize a structure that combines the exposure of college students to the professional environment with a didactic and self-reflective curriculum, thereby supporting students in their early professional development. We conclude that educational efforts aimed at developing professional identity and behaviour can begin before students enter medical school.

    Adolescents with ADHD are at risk of functional problems that may be mitigated by consistent ADHD treatment. This study pilots a brief intervention for adolescents with ADHD and their parents to increase treatment knowledge and family motivation to seek treatment. The 3-hr curriculum was developed by a multidisciplinary team and included psychoeducation, goal setting, and motivational interviewing. Fifteen adolescents and 20 caregivers participated in the workshop, completed pre- and post-test assessments, and reported on acceptability. Acceptability and satisfaction with the intervention were high. Perceived knowledge of ADHD increased post intervention; stigma was unchanged. Parents reported more acceptability of stimulant medications and less willingness to use special diets or cognitive games. Family feedback informed modifications to the curriculum. The Teen ADHD Workshop is a feasible and acceptable intervention to increase knowledge of ADHD and evidence-based treatments. Further research will evaluate effects on treatment participation.

    Full Text Available Aim. The aim of the present study was to investigate the effect of cornel iridoid glycoside (CIG on tau hyperphosphorylation induced by wortmannin (WT and GF-109203X (GFX and the underlying mechanisms. Methods. Human neuroblastoma SK-N-SH cells were preincubated with CIG (50, 100, and 200 µg/ml, resp. for 24 h and then exposed to 10 µM WT and 10 µM GFX for 3 h after washing out CIG. Immunohistochemistry was used to observe the microtubular cytoskeleton of the cultured cells. Western blotting was used to measure the phosphorylation level of tau protein, glycogen synthase kinase 3β (GSK-3β, and protein phosphatase 2A (PP2A. The activity of PP2A was detected by a biochemical assay. Results. Preincubation of CIG significantly attenuated the WT/GFX-induced tau hyperphosphorylation at the sites of Thr205, Thr212, Ser214, Thr217, Ser396, and PHF-1 and improved the damage of morphology and microtubular cytoskeleton of the cells. CIG did not prevent the decrease in p-AKT-ser473 and p-GSK-3β-ser9 induced by WT/GFX. However, CIG significantly elevated the activity of PP2A by reducing the demethylation of PP2A catalytic subunit (PP2Ac at Leu309 and the ratio of PME-1/LCMT in the WT/GFX-treated cells. The results suggest that CIG may be beneficial to the treatment of AD.

    Cornel iridoid glycoside (CIG) is a main component extracted from a traditional Chinese herb Cornus officinalis. Our previous study found that CIG improved neurological function in cerebral ischemic rats. The aim of this study was to investigate the therapeutic benefit of CIG in rats with fimbria-fornix transection (FFT) and explore the underlying molecular mechanisms. CIG (20, 60 and 180 mg/kg) or vehicle was intragastrically administered once daily to rats, starting immediately after the surgery and lasting for 4 weeks. Morris water maze and step-through tests showed that the memory deficits seen in FFT rats were significantly improved by CIG treatment. Immunohistochemical analysis showed that CIG treatment attenuated the loss of neurons in hippocampus. To elucidate the memory-improving mechanism of CIG, the neurotrophic factors, synaptic proteins and Bcl-2 family proteins in hippocampus were measured by Western blot analysis. FFT reduced hippocampal protein levels of nerve growth factor (NGF), tyrosine receptor kinase A (Trk A), brain-derived neurotrophic factor (BDNF), synaptophysin (SYP) and B-cell lymphoma-2 (Bcl-2), but not levels of tyrosine receptor kinase B (Trk B) and growth-associated protein 43 (GAP-43). FFT also elevated cytochorome C (Cyt c) and bcl-2-associated X protein (Bax). Administration of CIG to FFT rats significantly elevated the expression of NGF, TrkA, BDNF, SYP, GAP-43 and Bcl-2, and decreased the expression of Cyt c and Bax. These results indicated that CIG effectively counteracted cognitive impairments caused by fimbria-fornix lesions, and the mechanisms might be related to promoting neuronal survival and providing a beneficial environment for brain repair.

    In his book"Philosophy as Rigorous Science", Husserl tries to make philosophy a rigorous science, while the rigorous-ness of the science differs from the basic properties of natural science, and it is the essential feature of philosophy. As rigorous science, philosophy is in fact transcendental phenomenology mentioned by Husserl. Husserl determined philosophy as a rigor-ous science in the critiques of experimental psychology and his-torical relativism.%胡塞尔在其书《哲学作为严格的科学》一书中试图使哲学成为一种严格的科学,而此科学的严格性特点是有别于自然科学的基本特性的,它是哲学的本质特征。作为严格科学的哲学其实就是胡塞尔所说的先验现象学,胡塞尔是在对实验心理学、历史相对主义的批判中确立哲学为一门严格科学的思想的。

    2011-08-01

    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.

    欧洲的中世纪被很多人认为是科学史上的"黑暗时期",是科技发展的"漫漫长夜"。虽然中世纪的基督教对科学造成了摧残,但是中世纪的科学还是有了缓慢的发展,似乎并没有一些学者所认为的中世纪完全是被黑暗所包裹。那种启蒙历史观中的中世纪黑暗说,似乎由于更加深入的研究,这种说法正在完全地崩溃。正如丹皮尔所说"中世纪是近代的摇篮"。中世纪传承了古代文化,孕育了近代科学的萌芽。本文将从中世纪科学技术的成就以及科学文化的复苏—大学的兴起,这两个方面来说明中世纪的科技发展,以此来完全地否定黑暗时期的这种说法。%Medieval Europe is considered by many to be the "dark period" in the history of science,and "the night" of the development of science and technology.Although the medieval Christian causes devastation in science field,medieval science still developed slowly.The enlightenment view of history in the medieval darkness seems to be due to a more in-depth study,but this statement is complete collapse.As Dampier said,"The medieval times is the cradle of modern times".The medieval was the heritage of ancient culture,and gave birth to modern science budding.From the aspects of the achievement of science and technology in medieval times and the scientific and cultural revival——the rise of university,this paper elaborates the development of medieval science and technology,so as to completely deny the "dark period" argument.

    This article describes a 3-m-long vacuum chamber for the new wiggler magnet at the Cornell Electron Storage Ring (CESR) for the synchrotron light beam line of the Cornell High Energy Synchrotron Source (CHESS). Copper was chosen as the main chamber material for its good electric and thermal conductivities. Proper mechanical design and welding procedure were implemented to meet very tight tolerances to ensure adequate vertical aperture for the stored beams in CESR while allowing the required small wiggler gap. Distributed titanium sublimation pumping is incorporated along the 3 m length of the chamber to provide sufficient pumping speed and capacity for CESR and CHESS operations. The chamber pumping performance was evaluated prior to installation. Linear distributed pumping speeds at the beam line of ~720 l/s/m for N2 and CO and ~4000 l/s/m for H2 were measured. The measured pumping capacities for N2, CO and H2 are ~1.0, ~2.0 and ~77 Torr l, respectively, for each titanium sublimation cycle. Measurements also showed that CO molecules adsorb on the N2 and H2 saturated titanium films with virtually the same initial sticking coefficient as on a fresh titanium film. Analyses indicated very different CO adsorption mechanisms between the N2 and H2 saturated titanium films. While the replacement of surface H2 by CO was observed, little desorption of nitrogen was measured. Operational experience showed excellent vacuum pumping performance over two years after the chamber installation.

    Moore, A.; Derry, L.

    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

    Scheftel, Susan

    2009-01-01

    This paper explores the unique mind of the twentieth- century American artist Joseph Cornell, known for his boxes and collages made with "found" materials. The author interpolates reflections upon Cornell with vignettes from the treatment of a young child, speculating that certain individuals may possess a constellation of vulnerabilities/sensitivities that constitute what is referred to as a "cosmic" sensibility. It is suggested that such an orientation can lead variously to anxieties and separation problems, as well as (or in addition to) intellectual and/or artistic giftedness. The outcome of such dynamics would depend on a complex interplay of temperament, circumstance, and relational attunement.

  18. A Brief History of Context

    Wan, Kaiyu

    2009-01-01

    Context is a rich concept and is an elusive concept to define. The concept of context has been studied by philosophers, linguists, psychologists, and recently by computer scientists. Within each research community the term context was interpreted in a certain way that is well-suited for their goals, however no attempt was made to define context. In many areas of research in computer science, notably on web-based services, human-computer interaction (HCI), ubiquitous computing applications, and context-aware systems there is a need to provide a formal operational definition of context. In this brief survey an account of the early work on context, as well as the recent work on many working definitions of context, context modeling, and a formalization of context are given. An attempt is made to unify the different context models within the formalization. A brief commentary on the usefulness of the formalization in the development of context-aware and dependable systems is included.

    2010-01-02

    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.

    2011-03-01

    Human and animal toxicology has had a profound impact on our historical and current understanding of air pollution health effects. Early animal toxicological studies of air pollution had distinctively military or workplace themes. With the discovery that ambient air pollution episodes led to excess illness and death, there became an emergence of toxicological studies that focused on industrial air pollution encountered by the general public. Not only did the pollutants investigated evolve from ambient mixtures to individual pollutants but also the endpoints and outcomes evaluated became more sophisticated, resulting in our present state of the science. Currently, a large toxicological database exists for the effects of particulate matter and ozone, and we provide a focused review of some of the major contributions to the biological understanding for these two "criteria" air pollutants. A limited discussion of the toxicological advancements in the scientific knowledge of two hazardous air pollutants, formaldehyde and phosgene, is also included. Moving forward, the future challenge of air pollution toxicology lies in the health assessment of complex mixtures and their interactions, given the projected impacts of climate change and altered emissions on ambient conditions. In the coming years, the toxicologist will need to be flexible and forward thinking in order to dissect the complexity of the biological system itself, as well as that of air pollution in all its varied forms.

  2. Performance of the Visual Analogue Scale of Happiness and of the Cornell Scale for Depression in Dementia in the Tremembé Epidemiological Study, Brazil

    Directory of Open Access Journals (Sweden)

    Karolina G. César

    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.

    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.

    The aim of the present study was to investigate the effects of cornel iridoid glycoside (CIG) on behavioral changes and senescent status in senescence-accelerated mouse-prone 8 (SAMP8) mice at different ages (6, 10, and 14 months old). The learning and memory ability, the motor function and the aging conditions of SAMP8 mice were evaluated after CIG treatment in this study. Results showed that intragastrical administration of CIG (100 and 200mg/kg) for two months obviously improved the impaired cognitive ability of SAMP8 mice at the age of 6 months and 10 months, respectively. The treatment with CIG significantly increased the motor function of SAMP8 mice at 10 months and 14 months of age, respectively. CIG also evidently decreased the high grading score of senescence and increased the low surviving rate of SAMP8 mice at the age of 14 months. In addition, CIG treatment inhibited tau hyperphosphorylation in the hippocampus and striatum of SAMP8 mice at different ages. Together, these results indicate that CIG represent a potentially useful treatment for ameliorating the impaired cognitive ability, the motor dysfunction, aging conditions and hyperphosphorylation of tau in aging and age-related neurodegenerative diseases, such as Alzheimer's disease.

    2010-10-01

    Marissa Weiss, this year's AGU Mass Media Fellow, feels so strongly about communicating science that she and a fellow graduate student started a course on the subject. Three years ago, she and the other student in the biogeochemistry and environmental biocomplexity program at Cornell University, Ithaca, N. Y., developed—with the aid of mentors—a semester­long science communication class. The course has since become a regular offering at Cornell, where Weiss defended her dissertation in ecology this past August. A soil ecologist, Weiss showed in her thesis research that nitrogen pollution can cause slowing of soil decomposition because of a declining abundance of microbes that break the soil down.

    Full Text Available The Cornell Net Carbohydrate and Protein System was used to predict the nutrient utilization and milk production of buffaloes under complete confinement system of management. There were 243 lactation records involving the age of the animals, live weight, body condition score (BCS, milk production, % milk fat, % milk protein; climatic conditions and the actual feed ration. Simulation results showed that age, number of lactation, body weight and calving interval had no direct effect on the actual milk production and nutrient utilization of the dairy buffaloes. Significantly higher metabolizable energy (ME and metabolizable protein (MP allowable milk were predicted by the model compared to the actual milk production of the buffaloes. Using the actual ration, the model predicted 91 days for the buffaloes to gain one BCS while 70 days was needed when the CNCPS feed library is used. The model predicted significantly lower DMI (12.8 vs. I6kg/d and forage intake (9.10 vs. I0.3 kg/d with a difference of 21 % and 16 % than the actual ration. Significantly lower ME, (33.85 vs. 36.13 Mcal/ d was supplied by the actual ration but on the contrary, the MP supply (1,655 vs. 1,556 g/d was higher than the CNCPS feed library. Significantly higher ME, MP and mineral (Ca, P, and K balances were observed from the two rations indicating that more nutrients were supplied than what is required by the dairy buffaloes. The estimated manure and urine excretions were not significantly affected by the model predictions.

    The faecal egg count reduction test (FECRT) is the recommended method to monitor anthelmintic drug efficacy in cattle. There is a large variation in faecal egg count (FEC) methods applied to determine FECRT. However, it remains unclear whether FEC methods with an equal analytic sensitivity, but with different methodologies, result in equal FECRT results. We therefore, compared the bias, accuracy and precision of FECRT results for Cornell-Wisconsin (analytic sensitivity = 1 egg per gram faeces (EPG)), FLOTAC (analytic sensitivity = 1 EPG) and McMaster method (analytic sensitivity = 10 EPG) across four levels of egg excretion (1-49 EPG; 50-149 EPG; 150-299 EPG; 300-600 EPG). Finally, we assessed the sensitivity of the FEC methods to detect a truly reduced efficacy. To this end, two different criteria were used to define reduced efficacy based on FECR, including those described in the WAAVP guidelines (FECRT egg excretion increased, this effect was greatest for McMaster and least for Cornell-Wisconsin. The sensitivity of the three methods to detect a truly reduced efficacy was high (>90%). Yet, the sensitivity of McMaster and Cornell-Wisconsin may drop when drugs only show sub-optimal efficacy. Overall, the study indicates that the precision of FECRT is affected by the methodology of FEC, and that the level of egg excretion should be considered in the final interpretation of the FECRT. However, more comprehensive studies are required to provide more insights into the complex interplay of factors inherent to study design (sample size and FEC method) and host-parasite interactions (level of egg excretion and aggregation across the host population).

    Hawking, Stephen

    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.

    2015-03-01

    Full Text Available Neurolaw, as an interdisciplinary field which links the brain to law, facilitates the pathway to better understanding of human behavior in order to regulate it accurately through incorporating neuroscience achievements in legal studies. Since 1990's, this emerging field, by study on human nervous system as a new dimension of legal phenomena, leads to a more precise explanation for human behavior to revise legal rules and decision-makings. This paper strives to bring about significantly a brief introduction to neurolaw so as to take effective steps toward exploring and expanding the scope of law and more thorough understanding of legal issues in the field at hand.

    Abstract Question For many years, the term apparent life-threatening event (ALTE) was associated with sudden infant death syndrome, and parents who described an acute event in their infants were sent to the hospital for admission. I understand that for infants new terminology is recommended. What is the current approach to a near-death experience of an infant? Answer A recent clinical practice guideline revised the name and definition of an ALTE to a brief resolved unexplained event (BRUE). The diagnosis of BRUE in infants younger than 1 year of age is made when infants experience 1 of the following BRUE symptoms: a brief episode (ie, less than 1 minute and usually less than 20 to 30 seconds) that is entirely resolved (infant is at baseline), which remains unexplained after the history and physical examination are completed, and includes an event characterized by cyanosis or pallor; absent, decreased, or irregular breathing; hypertonia or hypotonia; or altered responsiveness. Low-risk infants should not be admitted to the hospital and overtesting is discouraged. PMID:28115439

    2009-05-01

    In March of 2008, the Cornell Electron Storage Ring (CESR) concluded twenty eight years of colliding beam operations for the CLEO high energy physics experiment. We have reconfigured CESR as an ultra low emittance damping ring for use as a test accelerator (CesrTA) for International Linear Collider (ILC) damping ring R&D. The primary goals of the CesrTA program are to achieve a beam emittance approaching that of the ILC Damping Rings with a positron beam, to investigate the interaction of the electron cloud with both low emittance positron and electron beams, to explore methods to suppress the electron cloud, and to develop suitable advanced instrumentation required for these experimental studies (in particular a fast x-ray beam size monitor capable of single pass measurements of individual bunches). We report on progress with the CESR conversion activities, the status and schedule for the experimental program, and the first experimental results that have been obtained.

    2014-01-01

    Science definitions, as the top priority in science teaching, are also language points which are easy to be ignored in junior high school students' learning. Due to some reasons such as the types of problems in examinations, many students and even some teachers ignore various definitions in science in varying degrees. Besides, the attributes of science definitions themselves make definition teaching dull and boring, making it inefficient whilst difficult for students to learn. Therefore, teachers should change the teaching methods of science defini-tions and improve the effectiveness of definition teaching.%科学概念是中学科学教学的重中之重,也是初中学生学习中容易被忽视的知识点。由于现有考试题型等原因导致很多学生乃至部分老师也对科学中的各种概念有不同程度的忽略,再是科学概念本身的性质,使得概念的教学变得枯燥乏味,缺乏成效,学生学习也障碍重重。因此教师应改变科学概念的教学方法,提高概念教学的有效性。

  9. Brief encounter networks

    CERN Document Server

    Kostakos, Vassilis; Penn, Alan

    2007-01-01

    Many complex human and natural phenomena can usefully be represented as networks describing the relationships between individuals. While these relationships are typically intermittent, previous research has used network representations that aggregate the relationships at discrete intervals. However, such an aggregation discards important temporal information, thus inhibiting our understanding of the networks dynamic behaviour and evolution. We have recorded patterns of human urban encounter using Bluetooth technology thus retaining the temporal properties of this network. Here we show how this temporal information influences the structural properties of the network. We show that the temporal properties of human urban encounter are scale-free, leading to an overwhelming proportion of brief encounters between individuals. While previous research has shown preferential attachment to result in scale-free connectivity in aggregated network data, we found that scale-free connectivity results from the temporal prope...

    As an important approach of promoting the trade con-tacts and economic communications of different countries, exhi-bitions have gradually been attached to wide importance. Science and technology exhibitions are dark horses, highlighting innova-tion and profession and becoming a bright spot of the exhibition industry with its profound connotation. Oriented by the govern-ment, science and technology exhibitions have achieved certain results. With the gradual expansion of the influence of science and technology exhibitions, the previous mode has been far from the requirements of the market. Therefore, the government should reorient its role in science and technology exhibitions and explore a new mode which is more suitable for market and enterprise op-eration.%会展作为一种促进世界各国贸易往来、经济交流的重要途径,日益受到广泛的重视。科技会展更是异军突起,突出创新性和专业性,以其深刻内涵成为会展业的亮点。目前科技会展大多是在政府主导下的,亦取得了一定业绩。科技会展随着其影响力的逐步扩大,原模式已远远不能满足市场的需求。因此,需要对政府在科技会展中的角色进行重新定位,探索一种更加贴近市场的、企业化运作新模式。

  2. Neuroophthalmology: a brief Vademecum.

    Science.gov (United States)

    Schwarz, Urs

    2004-01-01

    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 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.

    2005-01-01

    In this first of a two-paper sequence, we report techniques and results of the Cornell High-order Adaptive Optics Survey for brown dwarf companions (CHAOS). At the time of this writing, this study represents the most sensitive published population survey of brown dwarf companions to main sequence stars, for separation akin to our own outer solar system. The survey, conducted using the Palomar 200-inch Hale Telescope, consists of K-short coronagraphic observations of 80 main sequence stars out to 22 parsecs. At 1 arcsecond separations from a typical target system, the survey achieves median sensitivities 10 magnitudes fainter than the parent star. In terms of companion mass, the survey achieves typical sensitivities of 25 Jupiter masses (1 Gyr), 50 Jupiter masses (solar age), and 60 Jupiter masses (10 Gyr), using evolutionary models of Baraffe et al. (2003). Using common proper motion to distinguish companions from field stars, we find that no systems show positive evidence of a substellar companion (searchabl...

    To investigate the effect of cornel iridoid glycoside (CIG), an ingredient extracted from traditional Chinese herb Cornus offificinalis, on neurological function and infarct size in rats as measured by magnetic resonance imaging (MRI) after ischemic stroke. Sprague-Dawley rats were divided into three group: control (n=11), model (n=20) and CIG (n=16) groups. Rats in the model and CIG groups underwent 90-min middle cerebral artery occlusion (MCAO) followed by reperfusion. Their neurological defect was measured by using a modified neurological severity score (mNSS). T2-weighted MRI (T2-MRI) of the brain was performed in vivo from 2 to 28 days after MCAO. The infarct volume in the brain was also measured using 2,3,5-triphenyltetrazolium chloride (TTC) staining 28 days after stroke. CIG, 60 mg/(kg day), administered by oral gavage starting from 6 h after the onset of MCAO improved neurological function at 7, 14, 21, and 28 days post occlusion (PCIG-treated group compared with the model group at 7, 14 and 28 days after MCAO (PCIG-treated group than that in the model group (PCIG treatment, starting from 6 h after MCAO, reduced infarct size in the brain as measured by MRI and improved neurological function 2-28 days after focal cerebral ischemia in rats, suggesting that CIG could be a clinical application in improving stroke treatment.

  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 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.

    An exhibit of Cassini's images will open at NYC's American Museum of Natural History in March 2008 and then visit the Johnson Art Museum (Cornell) throughout fall 2008, including during next year's DPS. It is under consideration by several other venues in the States and overseas. The exhibit will feature 40-50 images, ranging from letter size to large posters, taken by remote-sensing instruments aboard Cassini and Huygens. Photos will be organized into a half-dozen thematic clusters (e.g., organized by celestial target or by physical process); a panel will introduce each grouping with individual images identified briefly. The Saturn system is a perfect vehicle to educate citizens about planetary science and origins. The images’ beauty should capture the public's attention, allowing us to then engage their curiosity about the relevant science. Among the Saturn system's broad suite of objects are Enceladus and Titan, two satellites of astrobiological interest; moreover, the rings display many processes active in other astrophysical disks. Several auxiliary ideas will be implemented. In Ithaca, we will project images at night against the museum's sand-colored exterior walls. A 10-12 minute musical composition has been commissioned from Roberto Sierra to open the show. We will encourage school children to participate in a human orrery circling the museum and will seek volunteers to participate in several Saturnalia. At Cornell we will involve the university and local communities, by taping their reactions to the images’ exquisite beauty as well as to their scientific content. Cassini will be the E/PO focus of next year's DPS meeting; those materials will be employed throughout the fall at New York schools and be available to travel with the show. We intend to work with NYC partners to offer teacher credits for associated weekend courses. We will produce classroom materials, including a DVD, for teacher use.

    Peda Nageswara Rao, Pinnamaneni

    2012-07-01

    strobiology is study of the origin, evolution, distribution and future of life on Earth and in the Universe. The discovery of amino acids in carbonaceous chondrite meteorites and complex organic molecules in interstellar clouds, comets and interplanetary dust forced biological interest into space research. The existence of different life forms in extreme environments of Earth, their ability to adapt and survive for long periods in stasis and then recover has given hope that life might exist on other planets. A lot more insight into the origin of life is gained by studying the analogous life on Earth to predict how extraterrestrial life might live. In this paper, a brief account is given on the exogenous and endogenous origin of life on Earth, biochemical basis of life, the need and approach for research in astrobiology, scientific strength of Indian institutions to launch space missions in search of life. A review of the results of the two balloon experiments carried out by Indian Space Research Organization (ISRO) in collaboration with many research institutes in the country as well as the studies carried out elsewhere is also given. An attempt made to address the limitations of the previous experiments, improvements needed, implications of engineering design changes to meet the gaps and institutional resources needed to carry out further studies in astrobiology in the Indian context. A few priority investigations that can be carried out in collaboration with premier national laboratories in India have been identified. A brief account of the international missions that are aimed at finding out habitable Earth-like planets is given. The educational opportunities and interdisciplinary unifying nature of astrobiology research are discussed. The paper concludes with an approach that can be adopted for coordinating the research in this new space science in a programmatic mode.

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

  2. NEWS: Why choose science?

    Science.gov (United States)

    2000-05-01

    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).

  4. Science policy for the '80s

    Science.gov (United States)

    Bell, Peter M.

    Science policy (if it ever was a policy) usually was to support ill-defined or ‘basic’ research in science; the ‘policy’ was embodied in the hope that supported research would someday pay off in the form of improved technology. One of the fathers of this policy during the post-WW-II period was Simon Ramo, a founding member of the National Academy of Engineering, chief scientist of United States ICBM defense operation, founder of the TRW Corporation, and now a member of President Reagan's science and technology task force. Simon Ramo represents an influential group dedicated to a ‘systems analysis’ approach to forecasting technological progress, and as such the ‘systems’ approach emerges as a central theme for science policy in the 1980s.The new shift in national policy introduced by the Reagan administration includes revisions in science policy that have recently been termed as ‘searching examination’ (Chemical & Engineering News, Feb. 23, 1981, p. 22), ‘Unkind cuts’ (New Scientist, Feb. 12, 1981), and ‘The Spectrum from Truth to Power’ (Science, Technology, and National Policy, edited by T. Kuehn and A. Porter, Cornell University Press, Ithaca, N.Y., 1981). The idea now is to speed the conversion of scientific discovery into technology in an orderly way. As never before, there are growing debates over the roles of science in society, its lines of support, its applications. More than ever, social scientists, economists, and philosophical types are trying their hand at influencing science policy in very different ways than scientists themselves, as Vannevar Bush did 30 years ago.

  8. 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.

    The Crisis Management Briefing (CMB) is a powerful and versatile crisis intervention tool, effective within a wide variety of populations, settings, and critical incidents. Initially proposed by Everly (2000), the CMB uniquely fills the factual information void following a critical incident. Additionally, a CMB provides essential information on effective coping strategies and available helping resources, tailored to the specific incident(s). The authors expand on the original CMB construct using their combined field experience, offering recommendations on team composition, strategic planning factors, using CISDs vs. CMBs, and specific enhancements for the four phases. They conclude with examples of specific interventions across a variety of events to illustrate their recommendations.

  3. Brief interventions for alcohol problems: a review.

    Science.gov (United States)

    Bien, T H; Miller, W R; Tonigan, J S

    1993-03-01

    Relatively brief interventions have consistently been found to be effective in reducing alcohol consumption or achieving treatment referral of problem drinkers. To date, the literature includes at least a dozen randomized trials of brief referral or retention procedures, and 32 controlled studies of brief interventions targeting drinking behavior, enrolling over 6000 problem drinkers in both health care and treatment settings across 14 nations. These studies indicate that brief interventions are more effective than no counseling, and often as effective as more extensive treatment. The outcome literature is reviewed, and common motivational elements of effective brief interventions are described. There is encouraging evidence that the course of harmful alcohol use can be effectively altered by well-designed intervention strategies which are feasible within relatively brief-contact contexts such as primary health care settings and employee assistance programs. Implications for future research and practice are considered.

    Full Text Available The Cornell Net Carbohydrate and Protein System (CNCPS model has been increasingly used in tropical regions for dairy and beef production. 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.

  8. 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.

    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.

    2011-01-01

    This issue's "Legal Briefing" column covers recent legal developments involving institutional healthcare ethics committees. This topic has been the subject of recent articles in JCE. Healthcare ethics committees have also recently been the subject of significant public policy attention. Disturbingly, Bobby Schindler and others have described ethics committees as "death panels." But most of the recent attention has been positive. Over the past several months, legislatures and courts have expanded the use of ethics committees and clarified their roles concerning both end-of-life treatment and other issues. These developments are usefully grouped into the following eight categories: 1. Existence and availability. 2. Membership and composition. 3. Operating procedures. 4. Advisory roles. 5. Decision-making and gate-keeping roles. 6. Confidentiality. 7. Immunity. 8. Litigation and court cases.

    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.

    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

  3. Cancer Vaccines: A Brief Overview.

    Thomas, Sunil; Prendergast, George C

    2016-01-01

    Vaccine approaches for cancer differ from traditional vaccine approaches for infectious disease in tending to focus on clearing active disease rather than preventing disease. In this review, we provide a brief overview of different types of vaccines and adjuvants that have been investigated for the purpose of controlling cancer burdens in patients, some of which are approved for clinical use or in late-stage clinical trials, such as the personalized dendritic cell vaccine sipuleucel-T (Provenge) and the recombinant viral prostate cancer vaccine PSA-TRICOM (Prostvac-VF). Vaccines against human viruses implicated in the development and progression of certain cancers, such as human papillomavirus in cervical cancer, are not considered here. Cancers express "altered self" antigens that tend to induce weaker responses than the "foreign" antigens expressed by infectious agents. Thus, immune stimulants and adjuvant approaches have been explored widely. Vaccine types considered include autologous patient-derived immune cell vaccines, tumor antigen-expressing recombinant virus vaccines, peptide vaccines, DNA vaccines, and heterologous whole-cell vaccines derived from established human tumor cell lines. Opportunities to develop effective cancer vaccines may benefit from seminal recent advances in understanding how immunosuppressive barricades are erected by tumors to mediate immune escape. In particular, targeted ablation of these barricades with novel agents, such as the immune checkpoint drug ipilimumab (anti-CTLA-4) approved recently for clinical use, may offer significant leverage to vaccinologists seeking to control and prevent malignancy.

    In the last two decades easy-to-use simple instruments have been developed and validated to assess specific aspects of the diet or a general profile that can be compared with a reference dietary pattern as the Mediterranean Diet or with the recommendations of the Dietary Guidelines. Brief instruments are rapid, simple and easy to use tools that can be implemented by unskilled personnel without specific training. These tools are useful both in clinical settings and in Primary Health Care or in the community as a tool for triage, as a screening tool to identify individuals or groups of people at risk who require further care or even they have been used in studies to investigate associations between specific aspects of the diet and health outcomes. They are also used in interventions focused on changing eating behaviors as a diagnostic tool, for self-evaluation purposes, or to provide tailored advice in web based interventions or mobile apps. There are some specific instruments for use in children, adults, elderly or specific population groups. Copyright AULA MEDICA EDICIONES 2015. Published by AULA MEDICA. All rights reserved.

  18. Brief Homeopathic Pathogenetic Experimentation: A Unique Educational Tool in Brazil

    Directory of Open Access Journals (Sweden)

    Marcus Zulian Teixeira

    2009-01-01

    Full Text Available In homeopathy, many difficulties are encountered in understanding theoretical presuppositions because they represent different paradigms from those of hegemonic science. In our medical school, we developed a brief homeopathic pathogenetic experimentation course to be added as curricular content and a didactic method in homeopathic disciplines to add practical experience to the theoretical approach of homeopathic presuppositions. In accordance with the premises laid out by Hahnemann, the father of homeopathy, brief pathogenetic experimentation was offered on a voluntary basis for students who were free of chronic diseases and who had not regularly used medication in the last 3 months. The clinical test, either crossed or sequential (randomized and blind, was used as a study model. Single weekly doses of a homeopathic medicine of 30 cH or placebo were taken by participants during 4 weeks after which crossover of the experimented substances took place for another 4 weeks. Polycrest medicines were used so that symptoms developed by the participants could be compared to those described in Homeopathic Materia Medica. Thirty-three of the 50 students who studied homeopathy as an elective discipline over the last 4 years at the School of Medicine of the University of São Paulo (FMUSP participated. Participants described symptoms according to specific methodology including many comments with peculiar characteristics and notable idiosyncrasies. All these students endorsed the course because it contributed to their understanding of how dynamized substances produced symptoms in healthy participants as well as the cure of symptoms according to the casual similitude principle. Brief homeopathic pathogenetic experimentation proved to be an effective method to observe the idiosyncratic manifestations of human individuality based on qualitative methodology, thus building a basis of understanding of homeopathy.

    A new smartphone application takes advantage of various technological capabilities and sensors to help users monitor air quality. Tapping into smartphone cameras, Global Positioning System (GPS) sensors, compasses, and accelerometers, computer scientists with the University of Southern California's (USC) Viterbi School of Engineering have developed a new application, provisionally entitled “Visibility.” Currently available for the Android telephone operating system, the application is available for free download at http://robotics.usc.edu/˜mobilesensing/Projects/AirVisibilityMonitoring. An iPhone application may be introduced soon. Smartphone users can take a picture of the sky and then compare it with models of sky luminance to estimate visibility. While conventional air pollution monitors are costly and thinly deployed in some areas, the smartphone application potentially could help fill in some blanks in existing air pollution maps, according to USC computer science professor Gaurav Sukhatme.

  13. Culture and Cognitive Science

    Michael Cole

    2003-03-01

    Full Text Available The purpose of this paper is to review the way in which cultural contributions to human nature have been treated within the field of  cognitive science. I was initially motivated to write about this topic when invited to give a talk to a Cognitive Science department at a sister university in California a few years ago. My goal, on that occasion, was to convince my audience, none of whom were predisposed to considering culture an integral part of cognitive science, that they would indeed benefit from recognizing some affinities between the ideas of some of the founders of cognitive science and ideas about culture emanating from the Soviet (now Russian cultural-historical school. My task in presenting this argument to the readers of  Outlines is most likely the mirror image of that earlier effort. On the one hand, the ideas of the cultural-historical school are well known to this readership and you do not need to be lectured on the topic by an American whose knowledge of the topic is no greater than your own. At best, the ways in which I have appropriated those ideas and put them to work might provide an opportunity to reflect on the strange fate of ideas when they move between national traditions of thought. On the other hand, owing to a double twist of fate (after all, what was an American doing in Moscow in 1962 doing post-doctoral work in psychology I was also present during the discussions leading to the founding of Cognitive Science in the early 1970’s and subsequently became a member of the Cognitive Science Program at UCSD in the early 1980’s, arguably one of the pioneering efforts to institutionalize this new discipline.My hope is this unusual confluence of experiences, and the ideas that they have generated, will be of some use to those who see value in a dialogue between these different intellectual projects. With this goal in mind, I will begin by providing my own brief history of key ideas associated with the origins of

    Tomisaku Kawasaki published the first English-language report of 50 patients with Kawasaki disease (KD) in 1974. Since that time, KD has become the leading cause of acquired heart disease among children in North America and Japan. Although an infectious agent is suspected, the cause remains unknown. However, significant progress has been made toward understanding the natural history of the disease and therapeutic interventions have been developed that halt the immune-mediated destruction of the arterial wall. We present a brief history of KD, review progress in research on the disease, and suggest avenues for future study. Kawasaki saw his first case of KD in January 1961 and published his first report in Japanese in 1967. Whether cases existed in Japan before that time is currently under study. The most significant controversy in the 1960s in Japan was whether the rash and fever sign/symptom complex described by Kawasaki was connected to subsequent cardiac complications in a number of cases. Pathologist Noboru Tanaka and pediatrician Takajiro Yamamoto disputed the early assertion of Kawasaki that KD was a self-limited illness with no sequelae. This controversy was resolved in 1970 when the first Japanese nationwide survey of KD documented 10 autopsy cases of sudden cardiac death after KD. By the time of the first English-language publication by Kawasaki in 1974, the link between KD and coronary artery vasculitis was well-established. KD was independently recognized as a new and distinct condition in the early 1970s by pediatricians Marian Melish and Raquel Hicks at the University of Hawaii. In 1973, at the same Hawaiian hospital, pathologist Eunice Larson, in consultation with Benjamin Landing at Los Angeles Children's Hospital, retrospectively diagnosed a 1971 autopsy case as KD. The similarity between KD and infantile periarteritis nodosa (IPN) was apparent to these pathologists, as it had been to Tanaka earlier. What remains unknown is the reason for the

  1. Continuous Briefing and User Participation in Building Projects

    Jensen, Per Anker

    2006-01-01

    Briefing is not just about specifying needs as requirements but also about evaluating how well design pro-posals fulfill the needs and aspirations. Furthermore, briefing is not only about building design. Briefing starts at the pre-project stage to create a basis for the project decision....... It includes an initial strategic brief-ing to define the overall vision and objectives. Parallel to the design briefing it is necessary to carry out a briefing process related to interior design and building operation and before the building is commissioned a briefing process related to moving...... into the building is required. A building project is often part of a change process of the organisation that is going to occupy the building, and this change process should be management carefully to reach a successful result. An important aspect of briefing is to manage the par-ticipation of the coming users...

    Eger, Martin

    1992-12-01

    This paper is a programmatic sketch of a line of theoretical investigation in the philosophy of science education. The basic idea is that philosophical hermeneutics is an appropriate framework for science education in most of its aspects. A brief discussion is given of hermeneutics in general, of the version of it developed by H. G. Gadamer, and of the reasons for its relevance to science and to the problem of meaning in science education. A key element in this approach is the suggestion that each science be biewed as a language. Arguments against the appropriateness of hermeneutics to natural science are also discussed. One application of the theory to ongoing educational research — ‘misconceptions’ — is specifically treated.

The newspaper article was based on a special issue of Nature and on a new resource for scientometrics called Nature Index. I show here arguments and sources of bias that, under the light of the principle in dubio pro reo, it is questionable to dispute the quality and efficiency of the Brazilian science on these grounds, as it was commented on the referred article. A brief overview of Brazilian science is provided for readers to make their own judgment.

  10. The Utility of Brief Cognitive Tests for Patients With Type 2 Diabetes Mellitus: A Systematic Review.

    Type 2 diabetes mellitus (T2DM) is associated with an increased risk for mild cognitive impairment and dementia in both middle-aged and older individuals. Brief cognitive tests can potentially serve as a reliable and cost effective approach to detect for cognitive decrements in clinical practice. This systematic review examined the utility of brief cognitive tests in studies with patients with T2DM. This systematic review was conducted according to guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. "PubMed," "PsychINFO," "ScienceDirect," and "ProQuest" electronic databases were searched to identify articles published from January 1, 2005 to December 31, 2015. The search yielded 22 studies, with only 8 using brief tests as a cognitive screening tool, whereas the majority using these tests as a measure of global cognitive functions. In regard to cognitive screening studies, most had failed to fulfil the standard reporting of diagnostic test accuracy criteria such as Standards for Reporting of Diagnostic Accuracy for dementia and cognitive impairment. Moreover, few studies reported discriminant indices such as sensitivity, specificity, and positive and negative predictive values of brief cognitive tests in detecting cognitive impairment in patients with T2DM. Among studies which used brief cognitive tests as a measure of global cognitive function, patients with diabetes tended to perform worse than patients without diabetes. Processing speed appeared to be particularly impaired among patients with diabetes, therefore, measures of processing speed such as the Digit Symbol Substitution Test may add value to brief cognitive tests such as the Montreal Cognitive Assessment. The Montreal Cognitive Assessment supplemented by the Digit Symbol Substitution Test indicate initial promise in screening for cognitive impairment in T2DM.

    Pass, Laura; Lejuez, Carl W; Reynolds, Shirley

    2017-07-31

    Depression in adolescence is a common and serious mental health problem. In the UK, access to evidence-based psychological treatments is limited, and training and employing therapists to deliver these is expensive. Brief behavioural activation for the treatment of depression (BATD) has great potential for use with adolescents and to be delivered by a range of healthcare professionals, but there is limited empirical investigation with this group. To adapt BATD for depressed adolescents (Brief BA) and conduct a pilot study to assess feasibility, acceptability and clinical effectiveness. Twenty depressed adolescents referred to the local NHS Child and Adolescent Mental Health service (CAMHs) were offered eight sessions of Brief BA followed by a review around one month later. Self- and parent-reported routine outcome measures (ROMs) were collected at every session. Nineteen of the 20 young people fully engaged with the treatment and all reported finding some aspect of Brief BA helpful. Thirteen (65%) required no further psychological intervention following Brief BA, and both young people and parents reported high levels of acceptability and satisfaction with the approach. The pre-post effect size of Brief BA treatment was large. Brief BA is a promising innovation in the treatment of adolescent depression. This approach requires further evaluation to establish effectiveness and cost effectiveness compared with existing evidence-based treatments for adolescent depression. Other questions concern the effectiveness of delivery in other settings and when delivered by a range of professionals.

  12. Physical experience enhances science learning.

    Science.gov (United States)

    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.

    Burns, Joseph A.

    2014-05-01

    I will use this opportunity to recall my professional career. Like many, I was drawn into the space program during the mid-60s and early 70s when the solar system’s true nature was being revealed. Previously, dynamical astronomy discussed the short-term, predictable motions of point masses; simultaneously, small objects (e.g., satellites, asteroids, dust) were thought boring rather than dynamically rich. Many of today’s most active research subjects were unknown: TNOs, planetary rings, exoplanets and debris disks. The continuing stream of startling findings by spacecraft, ground-based surveys and numerical simulations forced a renaissance in celestial mechanics, incorporating new dynamical paradigms and additional physics (e.g., energy loss, catastrophic events, radiation forces). My interests evolved as the space program expanded outward: dust, asteroids, natural satellites, rings; rotations, orbital evolution, origins. Fortunately for me, in the early days, elementary models with simple solutions were often adequate to gain a first-order explanation of many puzzles. One could be a generalist, always learning new things.My choice of research subjects was influenced greatly by: i) Cornell colleagues involved in space missions who shared results: the surprising diversity of planetary satellites, the unanticipated orbital and rotational dynamics of asteroids, the chaotic histories of solar system bodies, the non-intuitive behavior of dust and planetary rings, irregular satellites. ii) Teaching introductory courses in applied math, dynamics and planetary science encouraged understandable models. iii) The stimulation of new ideas owing to service at Icarus and on space policy forums. iv) Most importantly, excellent students and colleagues who pushed me into new research directions, and who then stimulated and educated me about those topics.If time allows, I will describe some of today’s puzzles for me and point out similarities between the past development in our

  16. Investigating the factor structure of the Questionnaire on Smoking Urges-Brief (QSU-Brief).

    Science.gov (United States)

    Toll, Benjamin A; Katulak, Nicole A; McKee, Sherry A

    2006-07-01

    This study was designed to investigate the proposed two-factor structure of the 10-item Questionnaire on Smoking Urges-Brief (QSU-Brief) and to provide evidence for the psychometric properties of this questionnaire using the seven-point scoring set from the original QSU study [Tiffany, S.T., Drobes, D.J. (1991). The development and initial validation of a questionnaire on smoking urges. British Journal of Addiction, 86, 1467-1476.]. The study sample (N=576) was comprised of smokers presenting for treatment. Although an initial exploratory factor analysis appeared to replicate the original factor analytic findings of Cox et al. [Cox, L.S., Tiffany, S.T., Christen, A.G. (2001). Evaluation of the brief questionnaire of smoking urges (QSU-Brief) in laboratory and clinical settings. Nicotine and Tobacco Research, 3, 7-16.], when subjected to confirmatory factor analyses, a five-item, two-factor model using the most robust items from the original QSU-Brief factor analysis was the best explanation of the data in the present study. Good internal consistency reliability estimates were also obtained with this model. These results suggest that this shortened form of the QSU-Brief can be used with the original seven-point scoring set as a reliable assessment of the dual nature of smoking urges in a treatment-seeking population.

  1. Integrating Contemplative Tools into Biomedical Science Education and Research Training Programs

    Directory of Open Access Journals (Sweden)

    Rodney R. Dietert

    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.

  4. 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.

    Full Text Available In this paper I try to sketch a brief history of new realism. Starting from nineteenth century idealism, I then move on to discuss twentieth century postmodernism, which, I argue, is the heir of idealism and the theoretical enemy of new realism. Finally, I offer a reconstruction of how and why contemporary new realism came into being and propose a few remarks on its future perspectives.

  13. DataStaR: Bridging XML and OWL in Science Metadata Management

    Science.gov (United States)

    Lowe, Brian

    DataStaR is a science data “staging repository” developed by Albert R. Mann Library at Cornell University that produces semantic metadata while enabling the publication of data sets and accompanying metadata to discipline-specific data centers or to Cornell’s institutional repository. DataStaR, which employs OWL and RDF in its metadata store, serves as a Web-based platform for production and management of metadata and aims to reduce redundant manual input by reusing named ontology individuals. A key requirement of DataStaR is the ability to produce metadata records conforming to existing XML schemas that have been adopted by scientific communities. To facilitate this, DataStaR integrates ontologies that directly reflect XML schemas, generates HTML editing forms, and “lowers” ontology axioms into XML documents compliant with existing schemas. This paper describes our approach and implementation, and discusses the challenges involved.

    Full Text Available Background This study presents the Polish validation of the Brief Illness Perception Questionnaire, a nine-item scale which was constructed to assess the cognitive and emotional representations of illness among Polish patients. This tool is derived from the Common-Sense Model of Self-Regulation of Health and Illness. Participants and procedure This study included 923 chronically ill people with the following diseases: eczema (E, bronchial asthma (BA, chronic obstructive pulmonary disease (COPD, rheumatoid arthritis (RA, Hashimoto’s disease (HD, diabetes type II (D, acne (A, glaucoma and cataract (G, C, HIV/AIDS, ischaemic heart disease (IHD, psoriasis (P, breast and stomach cancer (C, and multiple sclerosis (MS. Test–retest reliability was assessed in 358 patients with selected chronic illnesses. Concurrent validity was assessed by correlating Kurtzke’s EDSS and the Brief IPQ in 140 MS patients. Discriminant validity was verified by comparing means for the tool among four groups of patients. Results The Polish version of the Brief IPQ showed good test–retest reliability. The scale also demonstrates good concurrent validity in MS patients. The discriminant validity of the Brief IPQ was supported by its ability to distinguish among different illnesses. Conclusions The Brief IPQ is a good, short and easy to use tool for assessing the perceptions of illness among Polish patients.

    The utility of short tandem repeat genetic (STR) markers for forensic science is beyond question and there are over 50 million STR profiles in current national databases. The magnitude and value of those data, however, are likely to be dwarfed by what is emerging from large-scale SNP and DNA sequence assays. Phenotypic characterization may well accompany future statements about identity. In this very brief review we focus on the use of rare variants to describe relatedness and population structure.

    This is a brief summary of the science findings of the Magellan mission, principally based on data from the radar system. Future plans for Magellan include acquisition of high resolution gravity data from a nearly circular orbit and atmospheric drag and occultation experiments. The Magellan science results represent the combined effort of more than 100 Magellan investigators and their students and colleagues. More extensive discussions can be found in the August and October, 1992 issues of the Journal of Geophysical Research, Planets. The Magellan mission's scientific objectives were to provide a global characterization of landforms and tectonic features; to distinguish and understand impact processes; to define and explain erosion, deposition, and chemical processes; and to model the interior density distribution. All but the last objective, which requires new global gravity data, have been accomplished, or we have acquired the data that are required to accomplish them.

  5. 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

    2016-01-01

    Science communication has the characteristics of objectivity, neutrality and rationality, the communication effects in all three levels of cognition, attitude and behavior. Introducing the important concept“Empathy”which originally belongs to the field of psychology into science communication is helpful in interpreting the success of “Under the Dome”, which is to keep the audience communicating with the speaker, listening patiently and sharing with others actively in a state of empathy. Effective science communication should combine humanistic and scientific spirit.%科学传播具有客观、中立和理性的特色,与人的情绪、情感相结合,可以促进并提升认知、态度和行为三个层面的传播效果。将“共情”这一原本属于心理学领域的重要概念引入科学传播去解读《穹顶之下》的成功,其可取之处在于能够引领受众达到共情状态,互动交流、耐心倾听、主动分享,从人文精神与科学精神双重领域进行有效的科学传播。

Quasi-experimental differences in observed baseline characteristics between BI and BT patients were adjusted using propensity score techniques. Incremental comparison of costs and health outcomes associated with BI and BT. Health-care settings in four US states participating in Substance Abuse and Mental Health Services Administration SBIRT grant programs. Ninety patients who received BT and 878 who received BI. Per-patient cost of SBIRT, patient demographics and six measures of substance use: proportion using alcohol, proportion using alcohol to intoxication, days of alcohol use, days of alcohol use to intoxication, proportion using drugs and days using drugs. BI and BT were associated with better outcomes. The cost of SBIRT was significantly higher for BT patients ($75.54 versus 16.32, 95% confidence interval, P brief treatment if the goal is to abstain from alcohol. However, the higher effectiveness of brief treatment for this outcome is associated with considerable uncertainty and, because both brief intervention and brief treatment improve all outcomes, brief treatment does not appear to be a good use of resources. © 2017 Society for the Study of Addiction.

  1. Delta undulator for Cornell energy recovery linac

    Directory of Open Access Journals (Sweden)

    Alexander B. Temnykh

    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.

    A lecture was presented by the author at the Democratic Opinion Forum on Health Teaching and Research, organized by Mexico's National Health Institutes Coordinating Office, at National Cardiology Institute "Ignacio Chavez", where he presented a critical review of the conventional classification of basic and applied science, as well as his personal view on health science teaching and research. According to the author, "well-conducted science" is that "generating reality-checked knowledge" and "mis-conducted science" is that "unproductive or producing 'just lies' and 'non-fundable'. To support his views, the author reviews utilitarian and pejorative definitions of science, as well as those of committed and pure science, useful and useless science, and practical and esoterical science, as synonyms of applied and basic science. He also asserts that, in Mexico, "this classification has been used in the past to justify federal funding cutbacks to basic science, allegedly because it is not targeted at solving 'national problems' or because it was not relevant to priorities set in a given six-year political administration period". Regarding health education and research, the author asserts that the current academic programs are inefficient and ineffective; his proposal to tackle these problems is to carry out a solid scientific study, conducted by a multidisciplinary team of experts, "to design the scientific researcher curricula from recruitment of intelligent young people to retirement or death". Performance assessment of researchers would not be restricted to publication of papers, since "the quality of scientific work and contribution to the development of science is not reflected by the number of published papers".

  4. Science teaching in science education

    Callahan, Brendan E.; Dopico, Eduardo

    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.

    2012-01-01

    Full Text Available Periodontal disease is a major public health issue and the development of effective therapies to treat the disease and regenerate periodontal tissue is an important goal of today′s medicine. Regeneration of periodontal tissue is perhaps one of the most complex process to occur in the body. Langer and colleagues proposed tissue engineering as a possible technique for regenerating the lost periodontal tissues. Tissue engineering is a multidisciplinary field, which involves the application of the principles and methods of engineering and life sciences to help in the development of biological substitutes to restore, maintain or improve the function of damaged tissues and organs. A Google/Medline search was conducted and relevant literature evaluating the potential role of the tissue engineering in periodontal regeneration, which included histological studies and controlled clinical trials, was reviewed. A comprehensive search was designed. The articles were independently screened for eligibility. Articles with authentic controls and proper randomization and pertaining specifically to their role in periodontal regeneration were included. The available literature was analyzed and compiled. The analysis indicate tissue engineering to be a promising, as well as an effective novel approach to reconstruct and engineer the periodontal apparatus. Here, we represent several articles, as well as recent texts that make up a special and an in-depth review on the subject. The purpose behind writing this brief review has been to integrate the evidence of research related to tissue engineering so as to implement them in our daily practice.

    Full Text Available This paper reports from bibliographic woven into three sections: a brief history of the prehispanic fishing, where the encounter between the indigenous communities of the State of Sinaloa and species that supported the incursion of primitive society in the various ecosystems are described water that make up the vast and varied territory of Sinaloa, where fishing is born as a function of interaction between society and nature through a deep empirical knowledge and a handmade primitive instrumentality that positions in the ecosystem within the flows of matter and energy. The importance of the species used for food fishing, religious symbolism and knowledge acquired and transmitted is denoted by the fishing process. In the second section the economic and social importance of fishing is contextualized, highlighting the current situation based on official information from the volumes recorded catch, species of economic importance and an account of the public policy process becomes mandataron fisheries, identifying transcendent moments on the national fisheries police and the current problem by going through today. Finally the episteme that addresses human resources training and scientific research supporting the fishing process Sinaloa taking the experience in developing the curriculum innovation plan of the Faculty of Marine Science in 2007 is discussed.

    Full Text Available Internet and the new media have been dramatically affecting the communication scenario. They are changing the role played by traditional media in the information processes, are creating new public spaces for dialogue and participation, and are triggering a short circuit among those producing and those receiving information. Even science communication is not stranger to the changes brought about by the new way of using and populating the web. An epitome of this process of change is the scientific podcast. This article will provide a brief review on the spreading and the purposes of podcasts in science communication, coming from a survey implemented as an activity of the course Science via podcast addressed to the second-year students of the Master in Science Communication of SISSA of Trieste.

  14. The Raychaudhuri equations: A brief review

    Indian Academy of Sciences (India)

    Sayan Kar; Soumitra Sengupta

    2007-07-01

    We present a brief review on the Raychaudhuri equations. Beginning with a summary of the essential features of the original article by Raychaudhuri and subsequent work of numerous authors, we move on to a discussion of the equations in the context of alternate non-Riemannian spacetimes as well as other theories of gravity, with a special mention on the equations in spacetimes with torsion (Einstein–Cartan–Sciama–Kibble theory). Finally, we give an overview of some recent applications of these equations in general relativity, quantum field theory, string theory and the theory of relativisitic membranes. We conclude with a summary and provide our own perspectives on directions of future research.

    Standring, Susan

    2016-07-01

    This brief history of topographical anatomy begins with Egyptian medical papyri and the works known collectively as the Greco-Arabian canon, the time line then moves on to the excitement of discovery that characterised the Renaissance, the increasing regulatory and legislative frameworks introduced in the 18th and 19th centuries, and ends with a consideration of the impact of technology that epitomises the period from the late 19th century to the present day. This paper is based on a lecture I gave at the Winter Meeting of the Anatomical Society in Cambridge in December 2015, when I was awarded the Anatomical Society Medal.

  17. A brief analysis on English etymology

    2015-01-01

    In the process of learning English, proficiency in vocabulary is the key point to study a language well. Obviously, it’s very crucial to know about the origin and history of the words. Research on English etymology is conducive to memory, interpretation and understanding of the words. Generally speaking, English etymology is closely connected with British history. Western culture also has exerted profound impact on English etymology, which leads to considerable borrowings pouring into English vocabulary. In brief, this dissertation will inquire into English etymology preliminarily.

  18. Revolutionary Science

    Directory of Open Access Journals (Sweden)

    Arturo Casadevall

    2016-05-01

    Full Text Available On rare occasions in the history of science, remarkable discoveries transform human society and forever alter mankind’s view of the world. Examples of such discoveries include the heliocentric theory, Newtonian physics, the germ theory of disease, quantum theory, plate tectonics and the discovery that DNA carries genetic information. The science philosopher Thomas Kuhn famously described science as long periods of normality punctuated by times of crisis, when anomalous observations culminate in revolutionary changes that replace one paradigm with another. This essay examines several transformative discoveries in the light of Kuhn’s formulation. We find that each scientific revolution is unique, with disparate origins that may include puzzle solving, serendipity, inspiration, or a convergence of disparate observations. The causes of revolutionary science are varied and lack an obvious common structure. Moreover, it can be difficult to draw a clear distinction between so-called normal and revolutionary science. Revolutionary discoveries often emerge from basic science and are critically dependent on nonrevolutionary research. Revolutionary discoveries may be conceptual or technological in nature, lead to the creation of new fields, and have a lasting impact on many fields in addition to the field from which they emerge. In contrast to political revolutions, scientific revolutions do not necessarily require the destruction of the previous order. For humanity to continue to benefit from revolutionary discoveries, a broad palette of scientific inquiry with a particular emphasis on basic science should be supported.

    Fraknoi, A.

    2004-12-01

    Dozens of scientists and science educators with advanced degrees in science have been writing literate and scientifically reasonable science fiction stories in the last two decades, although these are often drowned out by the din of popular magic teenagers and space battle epics. The paper will give examples of stories and novels with good science, which can be used as a way of making astronomy concepts "come alive" for non-science majors. A list of science fiction authors with astronomy and physics degrees will be included. We will also have examples from a web-site devoted to astronomy in science fiction (see link) that has some 200 brief reviews of stories organized by 40 astronomy topics. We will discuss how instructors are using such stories for classroom and homework assignments.

  8. Pre-flight safety briefings, mood and information retention.

    Science.gov (United States)

    Tehrani, Morteza; Molesworth, Brett R C

    2015-11-01

    Mood is a moderating factor that is known to affect performance. For airlines, the delivery of the pre-flight safety briefing prior to a commercial flight is not only an opportunity to inform passengers about the safety features on-board the aircraft they are flying, but an opportunity to positively influence their mood, and hence performance in the unlikely event of an emergency. The present research examined whether indeed the pre-flight safety briefing could be used to positively impact passengers' mood. In addition, the present research examined whether the recall of key safety messages contained within the pre-flight safety briefing was influenced by the style of briefing. Eighty-two participants were recruited for the research and divided into three groups; each group exposed to a different pre-flight cabin safety briefing video (standard, humorous, movie theme). Mood was measured prior and post safety briefing. The results revealed that pre-flight safety briefing videos can be used to manipulate passengers' mood. Safety briefings that are humorous or use movie themes to model their briefing were found to positively affect mood. However, there was a trade-off between entertainment and education, the greater the entertainment value, the poorer the retention of key safety messages. The results of the research are discussed from both an applied and theoretical perspective.

  9. A brief etymology of the collateral circulation.

    It is well known that the protective capacity of the collateral circulation falls short in many individuals with ischemic disease of the heart, brain, and lower extremities. In the past 15 years, opportunities created by molecular and genetic tools, together with disappointing outcomes in many angiogenic trials, have led to a significant increase in the number of studies that focus on: understanding the basic biology of the collateral circulation; identifying the mechanisms that limit the collateral circulation's capacity in many individuals; devising methods to measure collateral extent, which has been found to vary widely among individuals; and developing treatments to increase collateral blood flow in obstructive disease. Unfortunately, accompanying this increase in reports has been a proliferation of vague terms used to describe the disposition and behavior of this unique circulation, as well as the increasing misuse of well-ensconced ones by new (and old) students of collateral circulation. With this in mind, we provide a brief glossary of readily understandable terms to denote the formation, adaptive growth, and maladaptive rarefaction of collateral circulation. We also propose terminology for several newly discovered processes that occur in the collateral circulation. Finally, we include terms used to describe vessels that are sometimes confused with collaterals, as well as terms describing processes active in the general arterial-venous circulation when ischemic conditions engage the collateral circulation. We hope this brief review will help unify the terminology used in collateral research.

    Knuteson, Bruce

    2011-01-01

    The economic structure of basic science is currently socialist, funded by the public at large through taxes for the benefit of the public at large. This socialist system should be augmented by a capitalist system, in which basic science is also funded by private investors who reap financial benefit from the sale of subsequent technologies based on the knowledge obtained from the research funded by their investments. A capitalist system will provide benefits extending from the broad target audience of this paper -- which includes politicians, financiers, economists, and scientists in all fields -- to the average taxpayer and consumer. Capitalist science will better align the incentives of scientists with taxpayer interests, channel more money into basic science, lower your taxes, and generally improve the quality of your life.
