  1. Scientists Discover Sugar in Space

    . Glycolaldehyde is a simpler molecular cousin to table sugar, the scientists say. The sugar molecule was detected in a large cloud of gas and dust some 26,000 light-years away, near the center of our Galaxy. Such clouds, often many light-years across, are the material from which new stars are formed. Though very rarified by Earth standards, these interstellar clouds are the sites of complex chemical reactions that occur over hundreds of thousands or millions of years. So far, about 120 different molecules have been discovered in these clouds. Most of these molecules contain a small number of atoms, and only a few molecules with eight or more atoms have been found in interstellar clouds. The 12 Meter Telescope "Finding glycolaldehyde in one of these interstellar clouds means that such molecules can be formed even in very rarified conditions," said Hollis. "We don't yet understand how it could be formed there," he added. "A combination of more astronomical observations and theoretical chemistry work will be required to resolve the mystery of how this molecule is formed in space." "We hope this discovery inspires renewed efforts to find even more kinds of molecules, so that, with a better idea of the total picture, we may be able to deduce the details of the prebiotic chemistry taking place in interstellar clouds," Hollis said. The discovery was made by detecting faint radio emission from the sugar molecules in the interstellar cloud. Molecules rotate end-for-end, and as they change from one rotational energy state to another, they emit radio waves at precise frequencies. The "family" of radio frequencies emitted by a particular molecule forms a unique "fingerprint" that scientists can use to identify that molecule. The scientists identified glycolaldehyde by detecting six frequencies of radio emission in what is termed the millimeter-wavelength region of the electromagnetic spectrum -- a region between more-familiar microwaves and infrared radiation.

    control. The WDC enables this by making both kinds of sources available in the same search interface. c. Data provenance: the appropriateness of data for use in a specific model or analysis often depends upon the exact details of how data was gathered and processed. The WDC will aid this by curating standards for metadata that are as descriptive as practical of the collection procedures. "Plug and play" sensor interfaces will fill in metadata appropriate to each sensor without human intervention. d. Contextual search: discovering data based upon geological (e.g. aquifer) or geographic (e.g., location in a stream network) features external to metadata. e. Data-driven search: discovering data that exhibit quality factors that are not described by the metadata. The WDC will partner with researchers desiring contextual and data driven search, and make results available to all. Many major data providers (e.g. federal agencies) are not mandated to provide access to data other than those they collect. The HIS project assembled data from over 90 different sources, thus demonstrating the promise of this approach. Meeting the grand challenges listed above will greatly enhance scientists' ability to discover, interpret, access, and analyze water data from across domains and sources to test Earth system hypotheses.

    K2-138 is a moderately bright (V = 12.2, K = 10.3) main-sequence K star observed in Campaign 12 of the NASA K2 mission. It hosts five small (1.6-3.3 R⊕) transiting planets in a compact architecture. The periods of the five planets are 2.35, 3.56, 5.40, 8.26, and 12.76 days, forming an unbroken...... chain of near 3:2 resonances. Although we do not detect the predicted 2-5 minute transit timing variations (TTVs) with the K2 timing precision, they may be observable by higher-cadence observations with, for example, Spitzer or CHEOPS. The planets are amenable to mass measurement by precision radial...... velocity measurements, and therefore K2-138 could represent a new benchmark system for comparing radial velocity and TTV masses. K2-138 is the first exoplanet discovery by citizen scientists participating in the Exoplanet Explorers project on the Zooniverse platform....

  12. Discovering genes underlying QTL

    Energy Technology Data Exchange (ETDEWEB)

    Vanavichit, Apichart [Kasetsart University, Kamphaengsaen, Nakorn Pathom (Thailand)

    2002-02-01

    A map-based approach has allowed scientists to discover few genes at a time. In addition, the reproductive barrier between cultivated rice and wild relatives has prevented us from utilizing the germ plasm by a map-based approach. Most genetic traits important to agriculture or human diseases are manifested as observable, quantitative phenotypes called Quantitative Trait Loci (QTL). In many instances, the complexity of the phenotype/genotype interaction and the general lack of clearly identifiable gene products render the direct molecular cloning approach ineffective, thus additional strategies like genome mapping are required to identify the QTL in question. Genome mapping requires no prior knowledge of the gene function, but utilizes statistical methods to identify the most likely gene location. To completely characterize genes of interest, the initially mapped region of a gene location will have to be narrowed down to a size that is suitable for cloning and sequencing. Strategies for gene identification within the critical region have to be applied after the sequencing of a potentially large clone or set of clones that contains this gene(s). Tremendous success of positional cloning has been shown for cloning many genes responsible for human diseases, including cystic fibrosis and muscular dystrophy as well as plant disease resistance genes. Genome and QTL mapping, positional cloning: the pre-genomics era, comparative approaches to gene identification, and positional cloning: the genomics era are discussed in the report. (M. Suetake)

    Satellites provide a view from space of changes on the Earth's surface. This series of images from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) aboard the Orbview-2 satellite shows the dramatic change in the color of Lake Michigan during the summer. The bright color that appears in late summer is probably caused by calcium carbonate-chalk-in the water. Lake Michigan always has a lot of calcium carbonate in it because the floor of the lake is limestone. During most of the year the calcium carbonate remains dissolved in the cold water, but at the end of summer the lake warms up, lowering the solubility of calcium carbonate. As a result, the calcium carbonate precipitates out of the water, forming clouds of very small solid particles that appear as bright swirls from above. The phenomenon is appropriately called a whiting event. A similar event occured in 1999, but appears to have started later and subsided earlier. It is also possible that a bloom of the algae Microcystis is responsible for the color change, but unlikely because of Lake Michigan's depth and size. Microcystis blooms have occured in other lakes in the region, however. On the shore of the lake it is possible to see the cities of Chicago, Illinois, and Milwaukee, Wisconsin. Both appear as clusters of gray-brown pixels. Image courtesy the SeaWiFS Project, NASA/Goddard Space Flight Center, and ORBIMAGE

  4. Ernest Rutherford: scientist supreme

    International Nuclear Information System (INIS)

    Campbell, J.

    1998-01-01

    One hundred years ago this month, Ernest Rutherford a talented young New Zealander who had just spent three years as a postgraduate student in Britain left for Canada, where he was to do the work that won him a Nobel prize. All three countries can justifiably claim this great scientist as their own. Ernest Rutherford is one of the most illustrious scientists that the world has ever seen. He achieved enduring international fame because of an incredibly productive life, during which he altered our view of nature on three separate occasions. Combining brilliantly conceived experiments with much hard work and special insight, he explained the perplexing problem of naturally occurring radioactivity, determined the structure of the atom, and was the world's first successful alchemist, changing nitrogen into oxygen. Rutherford received a Nobel prize for the first discovery, but the other two would have been equally worthy candidates, had they been discovered by someone else. Indeed, any one of his other secondary achievements many of which are now almost forgotten would have been enough to bring fame to a lesser scientist. For example, he invented an electrical method for detecting individual ionizing radiations, he dated the age of the Earth, and briefly held the world record for the distance over which wireless waves could be detected. He predicted the existence of neutrons, he oversaw the development of large-scale particle accelerators, and, during the First World War, he led the allied research into the detection of submarines. In this article the author describes the life and times of Ernest Rutherford. (UK)

  5. Michigan E85 Infrastructure

    Sandstrom, Matthew M.

    2012-03-30

    This is the final report for a grant-funded project to financially assist and otherwise provide support to projects that increase E85 infrastructure in Michigan at retail fueling locations. Over the two-year project timeframe, nine E85 and/or flex-fuel pumps were installed around the State of Michigan at locations currently lacking E85 infrastructure. A total of five stations installed the nine pumps, all providing cost share toward the project. By using cost sharing by station partners, the $200,000 provided by the Department of Energy facilitated a total project worth $746,332.85. This project was completed over a two-year timetable (eight quarters). The first quarter of the project focused on project outreach to station owners about the incentive on the installation and/or conversion of E85 compatible fueling equipment including fueling pumps, tanks, and all necessary electrical and plumbing connections. Utilizing Clean Energy Coalition (CEC) extensive knowledge of gasoline/ethanol infrastructure throughout Michigan, CEC strategically placed these pumps in locations to strengthen the broad availability of E85 in Michigan. During the first and second quarters, CEC staff approved projects for funding and secured contracts with station owners; the second through eighth quarters were spent working with fueling station owners to complete projects; the third through eighth quarters included time spent promoting projects; and beginning in the second quarter and running for the duration of the project was spent performing project reporting and evaluation to the US DOE. A total of 9 pumps were installed (four in Elkton, two in Sebewaing, one in East Lansing, one in Howell, and one in Whitmore Lake). At these combined station locations, a total of 192,445 gallons of E85, 10,786 gallons of E50, and 19,159 gallons of E30 were sold in all reporting quarters for 2011. Overall, the project has successfully displaced 162,611 gallons (2,663 barrels) of petroleum, and reduced

  14. Discovering Phonemes of Bidayuh

    Directory of Open Access Journals (Sweden)

    Jecky Misieng

    2012-07-01

    Full Text Available There are generally three views of the notion of a phoneme. The structuralist view of the phoneme focuses on this language phenomenon as a phonetic reality. In discovering phonemes of a language, phonologists who hold this view will look for minimal contrasting pairs as a way to determine contrasting sounds of that language. They will also look for allophones or two sounds of the same phoneme which may appear in complementary distribution. This paper will discuss the possible application of the structuralist approach to analyzing the phonemes of a dialect of Bidayuh, one of the Malayo-Polynesian languages spoken in the northern region of Borneo.

    2018-05-01

    Through patenting and commercialization, scientists today can develop their work beyond a publication in a learned journal. Indeed, universities and governments are encouraging today's scientists and engineers to break their research out of the laboratory and into the commercial world. However, doing so is complicated and can be daunting for those more used to a research seminar than a board room. This book, written by experienced scientists and entrepreneurs, deals with businesses started by scientists based on innovation and sets out to clarify for scientists and engineers the steps necessary to take an idea along the path to commercialization and maximise the potential for success, regardless of the path taken.

    Fifty years ago, Otto Hahn, Lise Meitner and Fritz Strassmann discovered the process of nuclear fission which, more than other scientific discoveries to date, profoundly has changed the world and continues to influence our life significantly: This discovery made the up to then incontestable physicists' view of the atom as an inseparable whole suddenly shatter to pieces. It has brought about the invaluable advantages of a peaceful utilization of nuclear energy, and at the same time put scientists in the position to build the most terrible weapon ever, threatening mankind and earth with complete destruction. All this certainly is reason enough to recall the scientists, their work and the spirit of the time. (orig.) [de

  2. Top quark discovered

    International Nuclear Information System (INIS)

    1995-01-01

    Nine months after a careful announcement of tentative evidence for the long-awaited sixth 'top' quark, physicists from the CDF and DO experiments at Fermilab's Tevatron proton-antiproton collider declared on 2 March that they had finally discovered the top quark. Last year (June 1994, page 1), the CDF experiment at the Tevatron reported a dozen candidate top events. These, said CDF, had all the characteristics expected of top, but the difficulties of extracting the tiny signal from a trillion proton-antiproton collisions made them shy of claiming a discovery. For its part, the companion DO Tevatron experiment reported a few similar events but were even more guarded about their interpretation as top quarks. Just after these hesitant announcements, performance at the Tevatron improved dramatically last summer. After the commissioning of a new linear accelerator and a magnet realignment, the machine reached a new world record proton-antiproton collision luminosity of 1.28 x 10 31 per sq cm per s, ten times that originally planned. Data began to pour in at an unprecedented rate and the data sample grew to six trillion collisions. Luminosity has subsequently climbed to 1.7 x 10 31 . The top quark is the final letter in the alphabet of Standard Model particles. According to this picture, all matter is composed of six stronglyinteracting subnuclear particles, the quarks, and six weakly interacting particles, the leptons. Both sextets are neatly arranged as three pairs in order of increasing mass. The fifth quark, the 'beauty' or 'b' quark, was also discovered at Fermilab, back in 1977. Since then physicists have been eagerly waiting for the top to turn up, but have been frustrated by its heaviness - the top is some 40 times the mass of its 'beautiful' partner. Not only is the top quark the heaviest by far, but it is the only quark which has been actively hunted. After the quarry was glimpsed last year, the net has now been

    Scientific studies which directly impact the larger society require an engagement between the scientists and the larger public. With respect to research on climate change, many third-party groups report on scientific findings and thereby serve as an intermediary between the scientist and the public. In many cases, the third-party reporting misinterprets the findings and conveys inaccurate information to the media and the public. To remedy this, many scientists are now taking a more active role in conveying their work directly to interested parties. In addition, some scientists are taking the further step of engaging with the general public to answer basic questions related to climate change - even on sub-topics which are unrelated to scientists' own research. Nevertheless, many scientists are reluctant to engage the general public or the media. The reasons for scientific reticence are varied but most commonly are related to fear of public engagement, concern about the time required to properly engage the public, or concerns about the impact to their professional reputations. However, for those scientists who are successful, these engagement activities provide many benefits. Scientists can increase the impact of their work, and they can help society make informed choices on significant issues, such as mitigating global warming. Here we provide some concrete steps that scientists can take to ensure that their public engagement is successful. These steps include: (1) cultivating relationships with reporters, (2) crafting clear, easy to understand messages that summarize their work, (3) relating science to everyday experiences, and (4) constructing arguments which appeal to a wide-ranging audience. With these steps, we show that scientists can efficiently deal with concerns that would otherwise inhibit their public engagement. Various resources will be provided that allow scientists to continue work on these key steps.

  6. Chandra Discovers Cosmic Cannonball

    Science.gov (United States)

    2007-11-01

    One of the fastest moving stars ever seen has been discovered with NASA's Chandra X-ray Observatory. This cosmic cannonball is challenging theories to explain its blistering speed. Astronomers used Chandra to observe a neutron star, known as RX J0822-4300, over a period of about five years. During that span, three Chandra observations clearly show the neutron star moving away from the center of the Puppis A supernova remnant. This remnant is the stellar debris field created during the same explosion in which the neutron star was created about 3700 years ago. Chandra X-ray Image of RX J0822-4300 in Puppis A Chandra X-ray Image of RX J0822-4300 in Puppis A By combining how far it has moved across the sky with its distance from Earth, astronomers determined the neutron star is moving at over 3 million miles per hour. At this rate, RX J0822-4300 is destined to escape from the Milky Way after millions of years, even though it has only traveled about 20 light years so far. "This star is moving at 3 million miles an hour, but it's so far away that the apparent motion we see in five years is less than the height of the numerals in the date on a penny, seen from the length of a football field," said Frank Winkler of Middlebury College in Vermont. "It's remarkable, and a real testament to the power of Chandra, that such a tiny motion can be measured." Labeled Image of RX J0822-4300 in Puppis A Labeled Image of RX J0822-4300 in Puppis A "Just after it was born, this neutron star got a one-way ticket out of the Galaxy," said co-author Robert Petre of NASA's Goddard Space Flight Center in Greenbelt, Md. "Astronomers have seen other stars being flung out of the Milky Way, but few as fast as this." So-called hypervelocity stars have been previously discovered shooting out of the Milky Way with speeds around one million miles per hour. One key difference between RX J0822-4300 and these other reported galactic escapees is the source of their speed. The hypervelocity stars are

    2012-04-24

    A team composed of scientists from Michigan State University (MSU) and Michigan Technological University (MTU) assembled to better understand, document, and improve systems for using forest-based biomass feedstocks in the production of energy products within Michigan. Work was funded by a grant (DE-EE-0000280) from the U.S. Department of Energy (DOE) and was administered by the Michigan Economic Development Corporation (MEDC). The goal of the project was to improve the forest feedstock supply infrastructure to sustainably provide woody biomass for biofuel production in Michigan over the long-term. Work was divided into four broad areas with associated objectives: • TASK A: Develop a Forest-Based Biomass Assessment for Michigan – Define forest-based feedstock inventory, availability, and the potential of forest-based feedstock to support state and federal renewable energy goals while maintaining current uses. • TASK B: Improve Harvesting, Processing and Transportation Systems – Identify and develop cost, energy, and carbon efficient harvesting, processing and transportation systems. • TASK C: Improve Forest Feedstock Productivity and Sustainability – Identify and develop sustainable feedstock production systems through the establishment and monitoring of a statewide network of field trials in forests and energy plantations. • TASK D: Engage Stakeholders – Increase understanding of forest biomass production systems for biofuels by a broad range of stakeholders. The goal and objectives of this research and development project were fulfilled with key model deliverables including: 1) The Forest Biomass Inventory System (Sub-task A1) of feedstock inventory and availability and, 2) The Supply Chain Model (Sub-task B2). Both models are vital to Michigan’s forest biomass industry and support forecasting delivered cost, as well as carbon and energy balance. All of these elements are important to facilitate investor, operational and policy decisions. All

    This paper analyzes the influence key scientists have in the development of a science and technology system. In particular, this work appraises the influence that star scientists have on the productivity and impact of young faculty, as well as on the likelihood that these young researchers become a leading personality in science. Our analysis confirms previous results that eminent scientist have a prime role in the development of a scientific system, especially within the context of an emerging economy like Mexico. In particular, in terms of productivity and visibility, this work shows that between 1984 and 2001 the elite group of physicists in Mexico (approximate 10% of all scientists working in physics and its related fields) published 42% of all publications, received 50% of all citations and bred 18% to 26% of new entrants. In addition our work shows that scientists that enter the system by the hand of a highly productive researcher increased their productivity on average by 28% and the ones that did it by the hand of a highly visible scientist received on average 141% more citations, vis-à-vis scholars that did not published their first manuscripts with an eminent scientist. Furthermore, scholars that enter the system by the hand of a highly productive researcher were on average 2.5 more likely to also become a star. PMID:29543855

    This Staff Report suggests a modified approach designed to significantly increase the ability of all customer classes to participate and share in the benefits of competition. The concepts discussed in this Report are designed to ensure that rates are not increased for any customers as a result of restructuring and, where possible, rates are reduced through the use of rate reduction bonds. The program outlined in this Report is designed to fulfill five objectives. First, it protects the interests of smaller customers, including low-income residential customers and senior citizens. Second, the program provides opportunities to strengthen Michigan's business community. Third, the program includes funding for employee retraining to assure that utility employees are not negatively impacted by restructuring. Fourth, the phase-in program provides the utilities with the opportunity to prepare for competition so that they remain Michigan-based companies. Fifth, the program is designed to foster competition upon a level playing field. The Commission has jurisdiction over all investor electric utilities and rural electric cooperatives in Michigan. Municipal electric utilities are not subject to Commission jurisdiction. Although this Report discusses details regarding Consumers Power and Detroit Edison, its concepts and principles are intended to apply to all jurisdictional electric utilities

    2002-09-01

    This study attempted to establish an image of a science writer based on a synthesis of writing theory, models, and research literature on academic writing in science and other disciplines and to contrast this image with an actual prototypical image of scientists as writers of science. The synthesis was used to develop a questionnaire to assess scientists' writing habits, beliefs, strategies, and perceptions about print-based language. The questionnaire was administered to 17 scientists from science and applied science departments of a large Midwestern land grant university. Each respondent was interviewed following the completion of the questionnaire with a custom-designed semistructured protocol to elaborate, probe, and extend their written responses. These data were analyzed in a stepwise fashion using the questionnaire responses to establish tentative assertions about the three major foci (type of writing done, criteria of good science writing, writing strategies used) and the interview responses to verify these assertions. Two illustrative cases (a very experienced, male physical scientist and a less experienced, female applied biological scientist) were used to highlight diversity in the sample. Generally, these 17 scientists are driven by the academy's priority of publishing their research results in refereed, peer-reviewed journals. They write their research reports in isolation or as a member of a large research team, target their writing to a few journals that they also read regularly, use writing in their teaching and scholarship to inform and persuade science students and other scientists, but do little border crossing into other discourse communities. The prototypical science writer found in this study did not match the image based on a synthesis of the writing literature in that these scientists perceived writing as knowledge telling not knowledge building, their metacognition of written discourse was tacit, and they used a narrow array of genre

    The social media revolution is having a dramatic effect on the world of scientific publication. Scientists now publish their research interests, theories and outcomes across numerous channels, including personal blogs and other thematic web spaces where ideas, activities and partial results are discussed. Accordingly, information systems that facilitate access to scientific literature must learn to cope with this valuable and varied data, evolving to make this research easily discoverable and available to end users. In this paper we describe the incremental process of discovering web resources in the domain of agricultural science and technology. Making use of Linked Open Data methodologies, we interlink a wide array of custom-crawled resources with the AGRIS bibliographic database in order to enrich the user experience of the AGRIS website. We also discuss the SemaGrow Stack, a query federation and data integration infrastructure used to estimate the semantic distance between crawled web resources and AGRIS.

    It's a tough time to be a scientist: universities are shutting science departments, funding organisations are facing flat budgets, and many newspapers have dropped their science sections altogether. But according to Marc Kuchner, this anti-science climate doesn't have to equal a career death knell - it just means scientists have to be savvier about promoting their work and themselves. In "Marketing for Scientists", he provides clear, detailed advice about how to land a good job, win funding, and shape the public debate. As an astrophysicist at NASA, Kuchner knows that "marketing" can seem like a superficial distraction, whether your daily work is searching for new planets or seeking a cure for cancer. In fact, he argues, it's a critical component of the modern scientific endeavour, not only advancing personal careers but also society's knowledge. Kuchner approaches marketing as a science in itself. He translates theories about human interaction and sense of self into methods for building relationships - one o...

    2005-01-01

    At the beginning of the 20th century Kristian Birkeland (1867-1917), a Norwegian scientist of insatiable curiosity, addressed questions that had vexed European scientists for centuries. Why do the northern lights appear overhead when the Earth’s magnetic field is disturbed? How are magnetic storms connected to disturbances on the Sun? To answer these questions Birkeland interpreted his advance laboratory simulations and daring campaigns in the Arctic wilderness in the light of Maxwell’s newly discovered laws of electricity and magnetism. Birkeland’s ideas were dismissed for decades, only to be vindicated when satellites could fly above the Earth’s atmosphere. Faced with the depleting stocks of Chilean saltpeter and the consequent prospect of mass starvation, Birkeland showed his practical side, inventing the first industrial scale method to extract nitrogen-based fertilizers from the air. Norsk Hydro, one of modern Norway’s largest industries, stands as a living tribute to his genius. Hoping to demo...

  6. Scientists want more children.

    Directory of Open Access Journals (Sweden)

    Full Text Available Scholars partly attribute the low number of women in academic science to the impact of the science career on family life. Yet, the picture of how men and women in science--at different points in the career trajectory--compare in their perceptions of this impact is incomplete. In particular, we know little about the perceptions and experiences of junior and senior scientists at top universities, institutions that have a disproportionate influence on science, science policy, and the next generation of scientists. Here we show that having fewer children than wished as a result of the science career affects the life satisfaction of science faculty and indirectly affects career satisfaction, and that young scientists (graduate students and postdoctoral fellows who have had fewer children than wished are more likely to plan to exit science entirely. We also show that the impact of science on family life is not just a woman's problem; the effect on life satisfaction of having fewer children than desired is more pronounced for male than female faculty, with life satisfaction strongly related to career satisfaction. And, in contrast to other research, gender differences among graduate students and postdoctoral fellows disappear. Family factors impede talented young scientists of both sexes from persisting to research positions in academic science. In an era when the global competitiveness of US science is at risk, it is concerning that a significant proportion of men and women trained in the select few spots available at top US research universities are considering leaving science and that such desires to leave are related to the impact of the science career on family life. Results from our study may inform university family leave policies for science departments as well as mentoring programs in the sciences.

  20. MICHIGAN/INDIANA: Siberian Snakes strike again

    International Nuclear Information System (INIS)

    Anon.

    1993-01-01

    Full text: Siberian snakes are showing themselves to be even more deadly than expected in killing their prey, the depolarizing resonances which would make it very difficult to accelerate polarized protons to TeV energies at accelerators such as the Tevatron, UNK, LHC, and SSC. The snake concept was proposed in the mid-1970s by Siberians Yaroslav Derbenev and Anatoly Kondratenko at Novosibirsk, but the snakes lay almost dormant until Owen Chamberlain, Ernest Courant, Alan Krisch, and the late Kent Terwilliger organized the 1985 Superconducting Supercollider (SSC) polarized beam workshop in Ann Arbor, which highlighted the need to test the concept. The idea is to rotate the spin through 180° on each turn in the ring. With such successive spin flips, the depolarizing effects seen in one turn should be cancelled by an equal and opposite perturbation on the subsequent turn. The new Cooler Ring at the Indiana University Cyclotron Facility then seemed an excellent test site for these eager but untested serpents. The Michigan/lndiana/Brookhaven team led by Krisch constructed the world's first snake and found that it could easily overcome its initial enemy, the imperfection depolarizing resonances caused by ring magnet imperfections (January/February 1990, page 20). In the next few years the growing team of ''herpetologists'' showed that Siberian snakes could overcome all kinds of depolarizing resonances, including the intrinsic kind (caused by the vertical betatron oscillations which keep the beam focused) and the synchrotron resonances (caused by synchrotron oscillations in energy). The team also discovered a new type of snake that was inadvertently built into the cooling section. This socalled type-3 snake rotates the spin around the vertical direction. A full type-1 snake (such as the team's superconducting solenoid magnet) rotates the spin by 180° around the beam direction; a type-2 snake rotates the spin around the radial direction

  2. WFIRST CGI Adjutant Scientist

    Science.gov (United States)

    Kasdin, N.

    One of the most exciting developments in exoplanet science is the inclusion of a coronagraph instrument on WFIRST. After more than 20 years of research and development on coronagraphy and wavefront control, the technology is ready for a demonstration in space and to be used for revolutionary science. Good progress has already been made at JPL and partner institutions on the coronagraph technology and instrument design and test. The next five years as we enter Phase A will be critical for raising the TRL of the coronagraph to the needed level for flight and for converging on a design that is robust, low risk, and meets the science requirements. In addition, there is growing excitement over the possibility of rendezvousing an occulter with WFIRST/AFTA as a separate mission; this would both demonstrate that important technology and potentially dramatically enhance the science reach, introducing the possibility of imaging Earth-like planets in the habitable zone of nearby stars. In this proposal I will be applying for the Coronagraph Adjutant Scientist (CAS) position. I bring to the position the background and skills needed to be an effective liaison between the project office, the instrument team, and the Science Investigation Team (SIT). My background in systems engineering before coming to Princeton (I was Chief Systems Engineer for the Gravity Probe-B mission) and my 15 years of working closely with NASA on both coronagraph and occulter technology make me well-suited to the role. I have been a lead coronagraph scientist for the WFIRST mission from the beginning, including as a member of the SDT. Together with JPL and NASA HQ, I helped organize the process for selecting the coronagraphs for the CGI, one of which, the shaped pupil, has been developed in my lab. All of the key algorithms for wavefront control (including EFC and Stroke Minimization) were originally developed by students or post-docs in my lab at Princeton. I am thus in a unique position to work with

    Growing up in a middle-class Jewish home in the Bronx, I had only one professional goal: to become a physician. However, as with most of my Vietnam-era MD colleagues, I found my residency training interrupted by the Doctor Draft in 1968. Some of us who were academically inclined fulfilled this obligation by serving in the US Public Health Service as commissioned officers stationed at the National Institutes of Health. This experience would eventually change the entire trajectory of my career. Here I describe how, over a period of years, I transitioned from the life of a physician to that of a physician-scientist; my 50 years of work on cellular receptors; and some miscellaneous thoughts on subjects as varied as Nobel prizes, scientific lineages, mentoring, publishing, and funding.

  7. Astronomers Discover Fastest-Spinning Pulsar

    Science.gov (United States)

    2006-01-01

    Astronomers using the National Science Foundation's Robert C. Byrd Green Bank Telescope have discovered the fastest-spinning neutron star ever found, a 20-mile-diameter superdense pulsar whirling faster than the blades of a kitchen blender. Their work yields important new information about the nature of one of the most exotic forms of matter known in the Universe. Pulsar Graphic Pulsars Are Spinning Neutron Stars CREDIT: Bill Saxton, NRAO/AUI/NSF (Click on image for larger version) "We believe that the matter in neutron stars is denser than an atomic nucleus, but it is unclear by how much. Our observations of such a rapidly rotating star set a hard upper limit on its size, and hence on how dense the star can be.," said Jason Hessels, a graduate student at McGill University in Montreal. Hessels and his colleagues presented their findings to the American Astronomical Society's meeting in Washington, DC. Pulsars are spinning neutron stars that sling "lighthouse beams" of radio waves or light around as they spin. A neutron star is what is left after a massive star explodes at the end of its "normal" life. With no nuclear fuel left to produce energy to offset the stellar remnant's weight, its material is compressed to extreme densities. The pressure squeezes together most of its protons and electrons to form neutrons; hence, the name "neutron star." "Neutron stars are incredible laboratories for learning about the physics of the fundamental particles of nature, and this pulsar has given us an important new limit," explained Scott Ransom, an astronomer at the National Radio Astronomy Observatory and one of Hessels' collaborators on this work. The scientists discovered the pulsar, named PSR J1748-2446ad, in a globular cluster of stars called Terzan 5, located some 28,000 light-years from Earth in the constellation Sagittarius. The newly-discovered pulsar is spinning 716 times per second, or at 716 Hertz (Hz), readily beating the previous record of 642 Hz from a pulsar

  12. Market Barriers to Solar in Michigan

    Energy Technology Data Exchange (ETDEWEB)

    Miller, E.; Nobler, E.; Wolf, C.; Doris, E.

    2012-08-01

    The solar industry in the United States is at a turning point; the cost of PV hardware has declined substantially in recent years, placing new attention on reducing the balance of system (BOS) costs of solar that now contribute to a growing percentage of installation expenses. How states address these costs through the creation of a favorable policy and regulatory environment is proving to be a critical determinant of a thriving statewide solar market. This report addresses the permitting and tax issues that may stimulate the solar market growth in Michigan. By making PV installations easier to complete through reduced BOS costs, Michigan would become a more attractive location for manufacturers and installers. As PV module costs decline and BOS costs make up a greater share of the cost of solar, action taken today on these issues will prove beneficial in the long term, providing Michigan an opportunity to establish a leadership position in the solar industry.

    2018-03-01

    In this article we review the scientific contributions of Anthony Sclafani, with specific emphasis on his early work on the neural substrate of the ventromedial hypothalamic (VMH) hyperphagia-obesity syndrome, and on the development of diet-induced obesity (DIO). Over a period of 20 years Sclafani systematically investigated the neuroanatomical basis of the VMH hyperphagia-obesity syndrome, and ultimately identified a longitudinal oxytocin-containing neural tract contributing to its expression. This tract has since been implicated in mediating the effects of at least two gastrointestinal satiety factors. Sclafani was one of the first investigators to demonstrate DIO in rats as a result of exposure to multiple palatable food items (the "supermarket diet"), and concluded that diet palatability was the primary factor responsible for DIO. Sclafani went on to investigate the potency of specific carbohydrate and fat stimuli for inducing hyperphagia, and in so doing discovered that post-ingestive nutrient effects contribute to the elevated intake of palatable food items. To further investigate this effect, he devised an intragastric infusion system which allowed the introduction of nutrients into the gut paired with the oral intake of flavored solutions, an apparatus her termed the "electronic esophagus". Sclafani coined the term "appetition" to describe the effect of intestinal nutrient sensing on post-ingestive appetite stimulation. Sclafani's productivity in the research areas he chose to investigate has been nothing short of extraordinary, and his studies are characterized by inventive hypothesizing and meticulous experimental design. His results and conclusions, to our knowledge, have never been contradicted. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2015-11-01

    I was shaped by World War II, years of near starvation as a war refugee, postwar chaos, life in several countries, and relative affluence in later life. The truth is that as I was growing up I wanted to be a writer. My aspirations came to an end when, in order to speed up my graduation from college, I took courses in microbiology. It was my second love at first sight-that of my wife preceded it. I view science as an opportunity to discover the designs in the mosaics of life. What initiates my search of discovery is an observation that makes no sense unless there exists a novel design. Once the design is revealed there is little interest in filling all the gaps. I was fortunate to understand that what lasts are not the scientific reports but rather the generations of scientists whose education I may have influenced.

Subjects for consideration by the Committee can be submitted by the Director General either on his own behalf or on behalf of the Board. At its recent session, the Committee considered several aspects of the Agency's scientific programme, including the proposed conferences, symposia and seminars for 1960, scientific and technical publications, and the research contracts which had been or were to be awarded by the Agency. The programme of conferences for the current year had been approved earlier by the Board of Governors on the recommendation of the Committee. A provisional list of 17 conferences, symposia and seminars for 1960 was examined by the Committee and recommendations were made to the Director General. The Committee also examined the Agency's policy on the award of contracts for research work and studies. An important subject before the Committee was the principles and regulations for the application of Agency safeguards. Another subject considered by the Committee was the possibility of a project for an exchange of knowledge on controlled thermonuclear fusion. The Committee also examined a proposal for the determination of the world-wide distribution of hydrogen and oxygen isotopes in water.

    Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have discovered giant, ring-like structures around a cluster of galaxies. The discovery provides tantalizing new information about how such galaxy clusters are assembled, about magnetic fields in the vast spaces between galaxy clusters, and possibly about the origin of cosmic rays.

The giant radio arcs surrounding the cluster were discovered using the Very Large Array. The visible-light image is from the Digitized Sky survey. Below, an X-ray image of Abell 3376 made using the European Space Agency's XMM-Newton telescope shows a spectacular, bullet-shaped region of X-rays coming from gas heated to 60 million degrees Kelvin. The bullet shape results from the supersonic collision of a smaller smaller galaxy subcluster with the main body of the larger cluster. Click on images for larger version. X-Ray Image of Cluster Galaxy Cluster Abell 3376 (X-Ray) CREDIT: Joydeep Bagchi, IUCAA, ESA "These giant, radio-emitting rings probably are the result of shock waves caused by violent collisions of smaller groups of galaxies within the cluster," said Joydeep Bagchi, of the Inter-University Centre for Astronomy and Astrophysics in Pune, India, who led an international research team. The scientists reported their findings in the November 3 edition of the journal Science. The newly-discovered ring segments, some 6 million light-years across, surround a galaxy cluster called Abell 3376, more than 600 million light-years from Earth. They were revealed because fast-moving electrons emitted radio waves as they spiraled around magnetic field lines in intergalactic space.

    At the beginning of the 20th century Kristian Birkeland (1867-1917), a Norwegian scientist of insatiable curiosity, addressed questions that had vexed European scientists for centuries. Why do the northern lights appear overhead when the Earth's magnetic field is disturbed? How are magnetic storms connected to disturbances on the Sun? To answer these questions Birkeland interpreted his advance laboratory simulations and daring campaigns in the Arctic wilderness in the light of Maxwell's newly discovered laws of electricity and magnetism. Birkeland's ideas were dismissed for decades, only to be vindicated when satellites could fly above the Earth's atmosphere. Faced with the depleting stocks of Chilean saltpeter and the consequent prospect of mass starvation, Birkeland showed his practical side, inventing the first industrial scale method to extract nitrogen-based fertilizers from the air. Norsk Hydro, one of modern Norway's largest industries, stands as a living tribute to his genius. Hoping to demonstrate what we now call the solar wind, Birkeland moved to Egypt in 1913. Isolated from his friends by the Great War, Birkeland yearned to celebrate his 50th birthday in Norway. The only safe passage home, via the Far East, brought him to Tokyo where in the late spring of 1917 he passed away.

    very powerful tool that allows educators to address a diversity of topics ranging from ICT tools to the Exploration of our Universe. Instead of using traditional methods to teach about certain subjects for instance: stellar spectra, extra-solar planets or the classification of galaxies, they can use these powerful tools. Among other advantages a clear benefit of such tool is that teachers can use telescopes during regular classroom hours, provided they choose one located in the opposite part of the planet, where it is night time. Participants will also have the opportunity to use one of the radio antennas devoted for education from the EUHOU Consortium (European Hands-on Universe). A map of the arms of our galaxy will be built during the training session. Image Processing - After acquiring the images participants will be introduced to Salsa J, an image processing software that allows educators to explore the potential of astronomical images. The first example will be a simple measurement task: measuring craters on the Moon. Further exploration will guide them from luminosity studies to the construction of colour images, from making movies exhibiting the circular motion of the Sun to Jupiter Moons dance around the planet. e-learning repositories - In the ICT age it is very important that educators have support and know where to find meaningful and curriculum adapted resources for the construction of modern lessons. Some repositories will be presented in this session. Examples of such repositories are: Discover the Cosmos and EUHOU or a congregator of such repositories with quite advanced possibilities to support the work of teachers, the Open Discovery Space portal. This type of sessions are being successfully implemented by the Galileo Teacher Training Program team in Portugal under the scope of the EC funded GO-LAB project.

The seamless real-time integration, real-time visual interaction, and real-time processing capability allows a user to focus on critical management issues, conflicts, and constraints, to quickly and iteratively examine conceptual approximations, management and planning scenarios, and site characterization assumptions, to identify dominant processes, to evaluate data worth and sensitivity, and to guide further data-collection activities. We illustrate the power and effectiveness of the M-IGW modeling and visualization system with a real case study and a real-time, live demonstration.

  13. An Earth System Scientist Network for Student and Scientist Partnerships

    Ledley, T. S.

    2001-05-01

    Successful student and scientist partnerships require that there is a mutual benefit from the partnership. This means that the scientist needs to be able to see the advantage of having students work on his/her project, and the students and teachers need to see that the students contribute to the project and develop the skills in inquiry and the content knowledge in the geosciences that are desired. Through the Earth System Scientist Network (ESSN) for Student and Scientist Partnerships project we are working toward developing scientific research projects for the participation of high school students. When these research projects are developed they will be posted on the ESSN web site that will appear in the Digital Library for Earth System Education (DLESE). In DLESE teachers and students who are interested in participating in a research program will be able to examine the criteria for each project and select the one that matches their needs and situation. In this paper we will report on how the various ESSN research projects are currently being developed to assure that both the scientist and the students benefit from the partnership. The ESSN scientists are working with a team of scientists and educators to 1) completely define the research question that the students will be addressing, 2) determine what role the students will have in the project, 3) identify the data that the students and teachers will work with, 4) map out the scientific protocols that the students will follow, and 5) determine the background and support materials needed to facilitate students successfully participating in the project. Other issues that the team is addressing include 1) identifying the selection criteria for the schools, 2) identifying rewards and recognition for the students and teacher by the scientist, and 3) identifying issues in Earth system science, relevant to the scientists data, that the students and teachers could use as a guide help develop students investigative

  14. Glowing Hot Transiting Exoplanet Discovered

    Science.gov (United States)

    2003-04-01

    VLT Spectra Indicate Shortest-Known-Period Planet Orbiting OGLE-TR-3 Summary More than 100 exoplanets in orbit around stars other than the Sun have been found so far. But while their orbital periods and distances from their central stars are well known, their true masses cannot be determined with certainty, only lower limits. This fundamental limitation is inherent in the common observational method to discover exoplanets - the measurements of small and regular changes in the central star's velocity, caused by the planet's gravitational pull as it orbits the star. However, in two cases so far, it has been found that the exoplanet's orbit happens to be positioned in such a way that the planet moves in front of the stellar disk, as seen from the Earth. This "transit" event causes a small and temporary dip in the star's brightness, as the planet covers a small part of its surface, which can be observed. The additional knowledge of the spatial orientation of the planetary orbit then permits a direct determination of the planet's true mass. Now, a group of German astronomers [1] have found a third star in which a planet, somewhat larger than Jupiter, but only half as massive, moves in front of the central star every 28.5 hours . The crucial observation of this solar-type star, designated OGLE-TR-3 [2] was made with the high-dispersion UVES spectrograph on the Very Large Telescope (VLT) at the ESO Paranal Observatory (Chile). It is the exoplanet with the shortest period found so far and it is very close to the star, only 3.5 million km away. The hemisphere that faces the star must be extremely hot, about 2000 °C and the planet is obviously losing its atmosphere at high rate . PR Photo 10a/03 : The star OGLE-TR-3 .

  15. Professional Ethics for Climate Scientists

    Science.gov (United States)

    Peacock, K.; Mann, M. E.

    2014-12-01

    Several authors have warned that climate scientists sometimes exhibit a tendency to "err on the side of least drama" in reporting the risks associated with fossil fuel emissions. Scientists are often reluctant to comment on the implications of their work for public policy, despite the fact that because of their expertise they may be among those best placed to make recommendations about such matters as mitigation and preparedness. Scientists often have little or no training in ethics or philosophy, and consequently they may feel that they lack clear guidelines for balancing the imperative to avoid error against the need to speak out when it may be ethically required to do so. This dilemma becomes acute in cases such as abrupt ice sheet collapse where it is easier to identify a risk than to assess its probability. We will argue that long-established codes of ethics in the learned professions such as medicine and engineering offer a model that can guide research scientists in cases like this, and we suggest that ethical training could be regularly incorporated into graduate curricula in fields such as climate science and geology. We recognize that there are disanalogies between professional and scientific ethics, the most important of which is that codes of ethics are typically written into the laws that govern licensed professions such as engineering. Presently, no one can legally compel a research scientist to be ethical, although legal precedent may evolve such that scientists are increasingly expected to communicate their knowledge of risks. We will show that the principles of professional ethics can be readily adapted to define an ethical code that could be voluntarily adopted by scientists who seek clearer guidelines in an era of rapid climate change.

    The vertical distributions of 239 , 240 Pu, 238 Pu, and 137 Cs have been measured in sediment cores taken from Lake Michigan. Sections from a limited number of cores have been analyzed for 241 Am. In addition, grab samples from ten locations in the southern basin of the lake have been analyzed for phase distribution of 239 , 240 Pu using a sequential extraction technique. The results indicate that the 239 , 240 Pu, 238 Pu, and 137 Cs from weapons testing, and the 241 Am formed in situ are concentrated in the sediments. A comparison of the total deposition of 239 , 240 Pu and 137 Cs indicates that 137 Cs may be valuable as a monitor for 239 , 240 Pu deposition in the sediments. Values of the 238 Pu/ 239 , 240 Pu ratio are in agreement with values reported in Lake Ontario sediments (and Lake Michigan plankton) and show little variation with depth. 241 Am data support the concept of in situ production with little preferential mobility after formation. Studies of sedimentary phase distributions show that 239 , 240 Pu is associated with hydrous oxide phases which are chemically stable under the prevailing conditions in lake sediments. Since Lake Michigan sediments remain aerobic, relatively little 239 , 240 Pu is available for chemical mobilization from the hydrous oxide or organic phases present in the sediments

    2004-01-15

    Synthetic musk fragrances are added to a wide variety of personal care and household products and are present in treated wastewater effluent. Here we report for the first time ambient air and water measurements of six polycyclic musks (AHTN, HHCB, ATII, ADBI, AHMI, and DPMI) and two nitro musks (musk xylene and musk ketone) in North America. The compounds were measured in the air and water of Lake Michigan and in the air of urban Milwaukee, WI. All of the compounds except DPMI were detected. HHCB and AHTN were found in the highest concentrations in all samples. Airborne concentrations of HHCB and AHTN average 4.6 and 2.9 ng/m3, respectively, in Milwaukee and 1.1 and 0.49 ng/m3 over the lake. The average water concentration of HHCB and AHTN in Lake Michigan was 4.7 and 1.0 ng/L, respectively. A lake-wide annual mass budget shows that wastewater treatment plant discharge is the major source (3470 kg/yr) of the synthetic musks while atmospheric deposition contributes less than 1%. Volatilization and outflow through the Straits of Mackinac are major loss mechanisms (2085 and 516 kg/yr for volatilization and outflow, respectively). Concentrations of HHCB are about one-half the predicted steady-state water concentrations in Lake Michigan.

  19. One More Legacy of Paul F. Brandwein: Creating Scientists

    Science.gov (United States)

    Fort, Deborah C.

    2011-06-01

    This paper studies the influence of Paul F. Brandwein, author, scientist, teacher and mentor, publisher, humanist, and environmentalist, on gifted youngsters who later became scientists, based primarily on information gathered from surveys completed by 25 of his students and one colleague. It also traces his profound interactions with science educators. It illuminates the theories of Brandwein and his protégés and colleagues about the interaction of environment, schooling, and education and Brandwein's belief in having students do original research (that is, research whose results are unknown) on their way to discovering their future scientific paths. It tests Brandwein's 1955 hypothesis on the characteristics typical of the young who eventually become scientists, namely: Three factors are considered as being significant in the development of future scientists: a Genetic Factor with a primary base in heredity (general intelligence, numerical ability, and verbal ability); a Predisposing Factor, with a primary base in functions which are psychological in nature; an Activating Factor, with a primary base in the opportunities offered in school and in the special skills of the teacher. High intelligence alone does not make a youngster a scientist (p xix).

    2013-01-01

    Do scientists follow hot topics in their scientific investigations? In this paper, by performing analysis to papers published in the American Physical Society (APS) Physical Review journals, it is found that papers are more likely to be attracted by hot fields, where the hotness of a field is measured by the number of papers belonging to the field. This indicates that scientists generally do follow hot topics. However, there are qualitative differences among scientists from various countries, among research works regarding different number of authors, different number of affiliations and different number of references. These observations could be valuable for policy makers when deciding research funding and also for individual researchers when searching for scientific projects.

  2. Scientists and Educators: Joining Forces to Enhance Ocean Science Literacy

    Science.gov (United States)

    Keener-Chavis, P.

    2004-12-01

    The need for scientists to work with educators to enhance the general public's understanding of science has been addressed for years in reports like Science for All Americans (1990), NSF in a Changing World (1995), Turning to the Sea: America's Ocean Future (1999), Discovering the Earth's Final Frontier, A U.S. Strategy for Ocean Exploration (2000), and most recently, the U.S. Commission on Ocean Policy Report (2004). As reported in The National Science Foundation's Center for Ocean Science Education Excellence (COSEE) Workshop Report (2000), "The Ocean Sciences community did not answer (this) call, even though their discovery that the ocean was a more critical driving force in the natural environment than previously thought possessed great educational significance." It has been further acknowledged that "rapid and extensive improvement of science education is unlikely to occur until it becomes clear to scientists that they have an obligation to become involved in elementary- and secondary-level science (The Role of Scientists in the Professional Development of Science Teachers, National Research Council, 1996.) This presentation will focus on teachers' perceptions of how scientists conduct research, scientists' perceptions of how teachers should teach, and some misconceptions between the two groups. Criteria for high-quality professional development for teachers working with scientists will also be presented, along with a brief overview of the National Oceanic and Atmospheric Administration's Ocean Exploration program efforts to bring teachers and ocean scientists together to further ocean science literacy at the national level through recommendations put forth in the U.S. Commission on Ocean Policy Report (2004).

    The purpose of this project was to conduct the first comprehensive offshore wind assessment over Lake Michigan and to advance the body of knowledge needed to support future commercial wind energy development on the Great Lakes. The project involved evaluation and selection of emerging wind measurement technology and the permitting, installation and operation of the first mid-lake wind assessment meteorological (MET) facilities in Michigan’s Great Lakes. In addition, the project provided the first opportunity to deploy and field test floating LIDAR and Laser Wind Sensor (LWS) technology, and important research related equipment key to the sitting and permitting of future offshore wind energy development in accordance with public participation guidelines established by the Michigan Great Lakes Wind Council (GLOW). The project created opportunities for public dialogue and community education about offshore wind resource management and continued the dialogue to foster Great Lake wind resource utilization consistent with the focus of the GLOW Council. The technology proved to be effective, affordable, mobile, and the methods of data measurement accurate. The public benefited from a substantial increase in knowledge of the wind resources over Lake Michigan and gained insights about the potential environmental impacts of offshore wind turbine placements in the future. The unique first ever hub height wind resource assessment using LWS technology over water and development of related research data along with the permitting, sitting, and deployment of the WindSentinel MET buoy has captured public attention and has helped to increase awareness of the potential of future offshore wind energy development on the Great Lakes. Specifically, this project supported the acquisition and operation of a WindSentinel (WS) MET wind assessment buoy, and associated research for 549 days over multiple years at three locations on Lake Michigan. Four research objectives were defined for the

  9. The Local-Cosmopolitan Scientist

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available In contrast to previous discussions in the literature treating cosmopolitan and local as two distinct groups of scientists, this paperi demonstrates the notion of cosmopolitan and local as a dual orientation of highly motivated scientists. This dual orientation is derived from institutional motivation, which is a determinant of both high quality basic research and accomplishment of non-research organizational activities. The dual orientation arises in a context of similarity of the institutional goal of science with the goal of the organization; the distinction between groups of locals and cosmopolitans derives from a conflict between two goals.

    Scientists in less-developed countries (LDCs) that undertake nuclear programs become involved in political decisions on manpower and resource allocations that will preclude other options. Controversy over the adoption of sophisticated technology has put those who see science as the servant of society in conflict with those who see the pursuit of science as a social service. The role model which LDC scientists present in this issue has given them increasing power, which can be either in accord with or in conflict with the perceived national interest. 29 references

    BP Products North America Inc. (BP) owns and operates a petroleum refinery located on approximately 1,700 acres in Whiting, East Chicago, and Hammond, Indiana, near the southern tip of Lake Michigan. BP provided funding to Purdue University-Calumet Water Institute (Purdue) and Argonne National Laboratory (Argonne) to conduct studies related to wastewater treatment and discharges. Purdue and Argonne are working jointly to identify and characterize technologies that BP could use to meet the previous discharge permit limits for total suspended solids (TSS) and ammonia after refinery modernization. In addition to the technology characterization work, Argonne conducted a separate project task, which is the subject of this report. In Phase I of a two-part study, Argonne estimated the current levels of discharge to southern Lake Michigan from significant point and nonpoint sources in Illinois, Indiana, and portions of Michigan. The study does not consider all of the chemicals that are discharged. Rather, it is narrowly focused on a selected group of pollutants, referred to as the 'target pollutants'. These include: TSS, ammonia, total and hexavalent chromium, mercury, vanadium, and selenium. In Phase II of the study, Argonne will expand the analysis to cover the entire Lake Michigan drainage basin.

  15. Evaporite karst of northern lower Michigan

    Science.gov (United States)

    Black, T.J.

    1997-01-01

    Michigan has three main zones of evaporite karst: collapse breccia in Late Silurian deposits of the Mackinac Straits region; breccia, collapse sinks, and mega-block collapse in Middle Devonian deposits of Northern Lower Michigan, which overlaps the preceding area; and areas of soil swallows in sinks of Mississippian deposits between Turner and Alabaster in Arenac and Iosco counties, and near Grand Rapids in Kent County. The author has focused his study on evaporite karst of the Middle Devonian deposits. The Middle Devonian depos its are the Detroit River Group: a series consisting of limestone, dolomite, shale, salt, gypsum, and anhydrite. The group occurs from subcrop, near the surface, to nearly 1400 feet deep from the northern tip of the Southern Peninsula to the south edge of the "solution front" Glacial drift is from zero to 350 feet thick. Oil and gas exploration has encountered some significant lost-circulation zones throughout the area. Drilling without fluid returns, casing-seal failures, and lost holes are strong risks in some parts of the region. Lost fluid returns near the top of the group in nearby areas indicate some karst development shortly after deposition. Large and irregular lost-circulation zones, linear and patch trends of large sink holes, and 0.25 mile wide blocks of down-dropped land in the northern Lower Peninsula of Michigan were caused by surface- and ground-water movement along faults into the Detroit River Group. Glaciation has removed some evidence of the karst area at the surface. Sinkhole development, collapse valleys, and swallows developed since retreat of the glacier reveal an active solution front in the Detroit River Group.

    Fabritius discovered the first variable star, Mira, in 1596. Holwarda determined the 11 months period of Mira in 1638. Montanari discovered the next variable star, Algol, in 1669. Its period, 2.867 days, was determined by Goodricke (178). Algol was associated with demon-like creatures, "Gorgon" in ancient Greek and "ghoul" in ancient Arab mythology. This indicates that its variability was discovered much before 1669 (Wilk 1996), but this mythological evidence is ambiguous (Davis 1975). For thousands of years, the Ancient Egyptian Scribes (AES) observed stars for timekeeping in a region, where there are nearly 300 clear nights a year. We discovered a significant periodicity of 2.850 days in their calendar for lucky and unlucky days dated to 1224 BC, "the Cairo Calendar". Several astrophysical and astronomical tests supported our conclusion that this was the period of Algol three millennia ago. The "ghoulish habits" of Algol could explain this 0.017 days period increase (Battersby 2012).

    Diabetes is a serious disease that spread in the world dramatically. The diabetes patient has an average of risk to experience complications. Take advantage of recorded information to build ontology as information technology solution will help to predict patients who have average of risk level with certain complication. It is helpful to search and present patient's history regarding different risk factors. Discovering diabetes complications could be useful to prevent or delay the complications. We designed ontology based model, using adult diabetes patients' data, to discover the rules of diabetes with its complications in disease to disease relationship.

    1986-01-01

    A sampling of 210 university-employed radiation health scientists randomly selected from the membership lists of the Health Physics Society and the Radiation Research Society was polled in a secret ballot. The results support the positions that the public's fear of radiation is substantially greater than realistic, that TV, newspapers and magazines substantially exaggerate the dangers of radiation, that the amount of money now being spent on radiation protection is sufficient, and that the openness and honesty of U.S. government agencies about dangers of radiation were below average before 1972 but have been above average since then. Respondents give very high credibility ratings to BEIR, UNSCEAR, ICRP, and NCRP and to the individual scientists associated with their reports, and very low credibility ratings to those who have disputed them

  8. The Adam and Eve Robot Scientists for the Automated Discovery of Scientific Knowledge

    Science.gov (United States)

    King, Ross

    A Robot Scientist is a physically implemented robotic system that applies techniques from artificial intelligence to execute cycles of automated scientific experimentation. A Robot Scientist can automatically execute cycles of hypothesis formation, selection of efficient experiments to discriminate between hypotheses, execution of experiments using laboratory automation equipment, and analysis of results. The motivation for developing Robot Scientists is to better understand science, and to make scientific research more efficient. The Robot Scientist `Adam' was the first machine to autonomously discover scientific knowledge: both form and experimentally confirm novel hypotheses. Adam worked in the domain of yeast functional genomics. The Robot Scientist `Eve' was originally developed to automate early-stage drug development, with specific application to neglected tropical disease such as malaria, African sleeping sickness, etc. We are now adapting Eve to work with on cancer. We are also teaching Eve to autonomously extract information from the scientific literature.

  11. The Scientist as Sentinel (Invited)

    Oreskes, N.

    2013-12-01

    Scientists have been warning the world for some time about the risks of anthropogenic interference in the climate system. But we struggle with how, exactly, to express that warning. The norms of scientific behavior enjoin us from the communication strategies normally associated with warnings. If a scientist sounds excited or emotional, for example, it is often assumed that he has lost his capac¬ity to assess data calmly and therefore his conclusions are suspect. If the scientist is a woman, the problem is that much worse. In a recently published article my colleagues and I have shown that scientists have systematically underestimated the threat of climate change (Brysse et al., 2012). We suggested that this occurs for norma¬tive reasons: The scientific values of rationality, dispassion, and self-restraint lead us to demand greater levels of evidence in support of surprising, dramatic, or alarming conclusions than in support of less alarming conclusions. We call this tendency 'err¬ing on the side of least drama.' However, the problem is not only that we err on the side of least drama in our assessment of evidence, it's also that we speak without drama, even when our conclusions are dramatic. We speak without the emotional cadence that people expect to hear when the speaker is worried. Even when we are worried, we don't sound as if we are. In short, we are trying to act as sentinels, but we lack the register with which to do so. Until we find those registers, or partner with colleagues who are able to speak in the cadences that communicating dangers requires, our warnings about climate change will likely continue to go substantially unheeded.

    We used a long-term series of observations on alewife Alosa pseudoharengus abundance that was based on fall bottom-trawl catches to assess the importance of various abiotic and biotic factors on alewife recruitment in Lake Michigan during 1962–2002. We first fit a basic Ricker spawner–recruit model to the lakewide biomass estimates of age-3 recruits and the corresponding spawning stock size; we then fit models for all possible combinations of the following four external variables added to the basic model: an index of salmonine predation on an alewife year-class, an index for the spring–summer water temperatures experienced by alewives during their first year in the lake, an index of the severity of the first winter experienced by alewives in the lake, and an index of lake productivity during an alewife year-class's second year in the lake. Based on an information criterion, the best model for alewife recruitment included indices of salmonine predation and spring–summer water temperatures as external variables. Our analysis corroborated the contention that a decline in alewife abundance during the 1970s and early 1980s in Lake Michigan was driven by salmonine predation. Furthermore, our findings indicated that the extraordinarily warm water temperatures during the spring and summer of 1998 probably led to a moderately high recruitment of age-3 alewives in 2001, despite abundant salmonines.

  14. Youngest Stellar Explosion in Our Galaxy Discovered

    Science.gov (United States)

    2008-05-01

    Astronomers have found the remains of the youngest supernova, or exploded star, in our Galaxy. The supernova remnant, hidden behind a thick veil of gas and dust, was revealed by the National Science Foundation's Very Large Array (VLA) and NASA's Chandra X-Ray Observatory, which could see through the murk. The object is the first example of a "missing population" of young supernova remnants. 1985 and 2008 VLA Images Move cursor over image to blink. VLA Images of G1.9+0.3 in 1985 and 2008: Circle for size comparison. CREDIT: Green, et al., NRAO/AUI/NSF From observing supernovae in other galaxies, astronomers have estimated that about three such stellar explosions should occur in our Milky Way every century. However, the most recent one known until now occurred around 1680, creating the remnant called Cassiopeia A. The newly-discovered object is the remnant of an explosion only about 140 years ago. "If the supernova rate estimates are correct, there should be the remnants of about 10 supernova explosions in the Milky Way that are younger than Cassiopeia A," said David Green of the University of Cambridge in the UK, who led the VLA study. "It's great to finally track one of them down." Supernova explosions, which mark the violent death of a star, release tremendous amounts of energy and spew heavy elements such as calcium and iron into interstellar space. They thus seed the clouds of gas and dust from which new stars and planets are formed and, through their blast shocks, can even trigger such formation. The lack of evidence for young supernova remnants in the Milky Way had caused astronomers to wonder if our Galaxy, which appears otherwise normal, differed in some unknown way from others. Alternatively, scientists thought that the "missing" Milky Way supernovae perhaps indicated that their understanding of the relationship between supernovae and other galactic processes was in error. The astronomers made their discovery by measuring the expansion of the debris from

    Mozley, S.C.; Howmiller, R.P.

    1977-09-01

    This report summarizes Lake Michigan zoobenthic studies up to 1974, including reports of power-plant surveys. It describes ecologies of macroinvertebrate species and some microfauna, partly through use of data from other Great Lakes. The following are discussed: methodology of field surveys; zoobenthic indicators of pollution; zoobenthic effects on sediment-water exchanges; and numbers, biomass, and production of total macroinvertebrates. Prominent features of Lake Michigan zoobenthos include predominance of the amphipod Pontoporeia affinis, usefulness of tubificid oligochaetes in mapping environmental quality, and pronounced qualitative gradients in zoobenthos in relation to depth. Further research is needed on sampling methods, energy flow rates and pathways through benthic communities, factors limiting distribution of species near shore, and effects of macroinvertebrates on sediment chemistry and structure.

    There has been much concern about the impact of tight funding on the careers of young scientists. When only a small percentage of grants are approved, even the smallest problem or error with an application can push it out of the funding range. Unfortunately, the relative lack of grant writing skills by new investigators often has this effect. To avoid a situation where only experienced investigators with polished writing skills are funded, the National Institutes of Health has instituted a more generous ranking scale for new investigators. Not surprisingly, some senior investigators have protested, calling it reverse discrimination. I say that their anger is misplaced. New investigators do deserve a break.

    Fitzgerald, Scott D; Cooley, Thomas M; Murphy, Alice; Cosgrove, Melinda K; King, Betty A

    2004-04-01

    Sarcoptic mange is a cause of pruritic skin disease in domestic dogs and a wide range of wildlife species. We describe sarcoptic mange in free-ranging raccoons (Procyon lotor). Three adult raccoons from upper Wayne County, Michigan (USA), were captured, killed, and submitted for diagnostic evaluation. The animals were intensely pruritic, and two had advanced alopecic and crusting lesions over their dorsum and hind limbs. Skin scrapings and skin biopsies revealed crusting and hyperkeratotic dermatitis with high numbers of Sarcoptes scabiei adults, larvae, nymphs, and eggs. These raccoons were not otherwise debilitated, with minimal internal parasites, good body condition, and no evidence of infectious bacterial or viral diseases. Because sarcoptic mange is highly contagious and affects many species, including humans, transiently, it is important that wildlife biologists and rehabilitators include sarcoptic mange in their differential list for raccoons exhibiting pruritus and alopecia.

  3. Thermal discharge residence by Lake Michigan Salmonids

    Romberg, G.P.; Prepejchal, W.

    1975-01-01

    Lake Michigan salmon and trout were tagged with a thermoluminescent dosimeter (TLD) temperature tag to estimate their thermal exposure and residence time at a warm water discharge. Fish were collected, tagged, and released at the Point Beach Nuclear Plant, Two Rivers, Wisconsin, in the fall of 1973 and 1974. Tags were recovered during the same season, primarily from fish recaptured at Point Beach. Average uniform temperature exposure and maximum possible discharge residence time were determined. Appropriate hourly intake and discharge temperatures were averaged to calculate mean temperature exposure for the case of maximum discharge residence. Lowest discharge temperature not included within the period of maximum residence was identified to serve as a possible indicator of avoidance temperature. Mean values for the above parameters were calculated for fish species for each tagging year and are reported with the accompanying range of intake and discharge temperatures

    2017-07-01

    This article presents an analysis of how scientists are portrayed in the Lebanese national science textbooks. The purpose of this study was twofold. First, to develop a comprehensive analytical framework that can serve as a tool to analyze the image of scientists portrayed in educational resources. Second, to analyze the image of scientists portrayed in the Lebanese national science textbooks that are used in Basic Education. An analytical framework, based on an extensive review of the relevant literature, was constructed that served as a tool for analyzing the textbooks. Based on evidence-based stereotypes, the framework focused on the individual and work-related characteristics of scientists. Fifteen science textbooks were analyzed using both quantitative and qualitative measures. Our analysis of the textbooks showed the presence of a number of stereotypical images. The scientists are predominantly white males of European descent. Non-Western scientists, including Lebanese and/or Arab scientists are mostly absent in the textbooks. In addition, the scientists are portrayed as rational individuals who work alone, who conduct experiments in their labs by following the scientific method, and by operating within Eurocentric paradigms. External factors do not influence their work. They are engaged in an enterprise which is objective, which aims for discovering the truth out there, and which involves dealing with direct evidence. Implications for science education are discussed.

  7. Surficial geologic map of Berrien County, Michigan, and the adjacent offshore area of Lake Michigan

    The surficial geologic map of Berrien County, southwestern Michigan (sheet 1), shows the distribution of glacial and postglacial deposits at the land surface and in the adjacent offshore area of Lake Michigan. The geologic map differentiates surficial materials of Quaternary age on the basis of their lithologic characteristics, stratigraphic relationships, and age. Drill-hole information correlated in cross sections provides details of typical stratigraphic sequences that compose one or more penetrated geologic map units. A new bedrock geologic map (on sheet 2) includes contours of the altitude of the eroded top of bedrock and shows the distribution of middle Paleozoic shale and carbonate units in the subcrop. A sediment thickness map (also on sheet 2) portrays the extent of as much as 150 meters of surficial materials that overlie the bedrock surface.The major physical features of the county are related principally to deposits of the last Laurentide ice sheet that advanced and then retreated back through the region from about 19,000 to 14,000 radiocarbon years before present. Glacial and postglacial deposits underlie the entire county; shale bedrock crops out only in the adjacent offshore area on the bottom of Lake Michigan. All glacial deposits and glacial meltwater deposits in Berrien County are related to the late Wisconsinan glacial advances of the Lake Michigan ice lobe and its three regional recessional moraines, which cross the county as three north-northeast-trending belts.From east to west (oldest to youngest), the three moraine belts are known as the Kalamazoo, Valparaiso, and Lake Border morainic systems. The till-ridge morainic systems (Lake Border and local Valparaiso morainic systems) consist of multiple, elongate moraine ridges separated by till plains and lake-bottom plains. Tills in ground and end moraines in Berrien County are distinguished as informal units, and are correlated with three proposed regional till units in southwestern Michigan

    The Great Lakes Science Center has conducted lake-wide bottom trawl surveys of the fish community in Lake Michigan each fall since 1973. These systematic surveys are performed at depths of 9 to 110 m at each of seven index sites around Lake Michigan. Zebra mussel (Dreissena polymorpha) populations have expanded to all survey locations and at a level to sufficiently contribute to the bottom trawl catches. The quagga (Dreissena bugensis), recently reported in Lake Michigan, was likely in the catches though not recognized. Dreissena spp. biomass ranged from about 0.6 to 15 kg/ha at the various sites in 1999. Dreissenid mussels were found at depths of 9 to 82 m, with their peak biomass at 27 to 46 m. The colonization of these exotic mussels has ecological implications as well as potential ramifications on the ability to sample fish consistently and effectively with bottom trawls in Lake Michigan.

    2000-01-01

    There is ample data demonstrating that female scientists advance at a far slower rate than their male colleagues. The low numbers of female professors in European and North American universities is, thus, not solely an effect of few women in the recruitment pool but also to obstacles specific to the female gender. Together with her colleague Christine Wennerås, Agnes Wold conducted a study of the evaluation process at the Swedish Medical Research Council. Evaluators judged the "scientific competence", "research proposal" and "methodology" of applicants for post-doctoral positions in 1995. By relating the scores for "scientific competence" to the applicants' scientific productivity and other factors using multiple regression, Wennerås and Wold demonstrated that the applicant's sex exerted a strong influence on the "competence" score so that male applicants were perceived as being more competent than female applicants of equal productivity. The study was published in Nature (vol 387, p 341-3, 1997) and inspir...

    1985-01-01

    The coming together of many of the world's experts in nuclear physics in the 1930's was largely the result of the persecution of Jews in Germany and later in Italy. Initially this meant there were no jobs for young physicists to go into as the senior scientists had been sacked. Later, it resulted in the assembly of many of the world's foremost physicists in the United States, specifically at the Los Alamos Laboratory to work on the Manhattan Project. The rise of antisemitism in Italy (to where many physicists had fled at first) provoked the emigration of Fermi, the leading expert on neutrons at that time. The politics, physics and personalities in the 1930's, relevant to the development of nuclear energy, are discussed. (UK)

    FAIRNESS 2014 was the third edition in a series of workshops designed to bring together excellent international young scientists with research interests focused on physics at FAIR (Facility for Antiproton and Ion Research) and was held on September 22-27 2014 in Vietri sul Mare, Italy. The topics of the workshops cover a wide range of aspects in both theoretical developments and current experimental status, concentrated around the four scientific pillars of FAIR. FAIR is a new accelerator complex with brand new experimental facilities, that is currently being built next to the existing GSI Helmholtzzentrum for Schwerionenforschung close to Darmstadt, Germany. The spirit of the conference is to bring together young scientists, e.g. advanced PhD students and postdocs and young researchers without permanent position to present their work, to foster active informal discussions and build up of networks. Every participant in the meeting with the exception of the organizers gives an oral presentation, and all sessions are followed by an hour long discussion period. During the talks, questions are anonymously collected in a box to stimulate discussions. The broad physics program at FAIR is reflected in the wide range of topics covered by the workshop: • Physics of hot and dense nuclear matter, QCD phase transitions and critical point • Nuclear structure, astrophysics and reactions • Hadron Spectroscopy, Hadrons in matter and Hypernuclei • New developments in atomic and plasma physics • Special emphasis is put on the experiments CBM, HADES, PANDA, NUSTAR, APPA and related experiments For each of these different areas one invited speaker was selected to give a longer introductory presentation. The write-ups of the talks presented at FAIRNESS 2014 are the content of this issue of Journal of Physics: Conference Series and have been refereed according to the IOP standard for peer review. This issue constitutes therefore a collection of the forefront of research that

  5. The discovered preference hypothesis - an empirical test

    DEFF Research Database (Denmark)

    Lundhede, Thomas; Ladenburg, Jacob; Olsen, Søren Bøye

    Using stated preference methods for valuation of non-market goods is known to be vulnerable to a range of biases. Some authors claim that these so-called anomalies in effect render the methods useless for the purpose. However, the Discovered Preference Hypothesis, as put forth by Plott [31], offers...... an nterpretation and explanation of biases which entails that the stated preference methods need not to be completely written off. In this paper we conduct a test for the validity and relevance of the DPH interpretation of biases. In a choice experiment concerning preferences for protection of Danish nature areas...... as respondents evaluate more and more choice sets. This finding supports the Discovered Preference Hypothesis interpretation and explanation of starting point bias....

  9. What if Fleming had not discovered penicillin?

    What would have happened had Alexander Fleming not discovered penicillin in 1928? Perhaps the obvious answer is that, someone else would have discovered penicillin during 1930s and the Oxford group, would still have purified it sometime in the early 1940s. Here, however, in this counterfactual account of the penicillin story, it is argued that without Fleming, penicillin might still be undiscovered and the antibiotic age would never have dawned. As a result, many of the recent developments in medicine, such as organ transplantation, might have been delayed or, at best, made more hazardous. Penicillin might have come onto the scene a few years later but, had Fleming overlooked the discovery, it seems certain that penicillin would not have saved countless Allied lives, during and after D-Day. Instead of having enjoyed fifty and more years of the antibiotic age, it is argued here, that we would have had to rely upon highly developed sulphonamides, so-called "supasulfas", and other chemically-derived antibacterial drugs. Indeed, it might be the case that, even well into this new millennium, the antibiotic age has yet to dawn, and medicine is still waiting for someone to chance upon penicillin. Here we discuss what might have happened had Fleming not discovered penicillin and come to the conclusion that the medical armoury available today would have been far different and might have relied solely upon highly developed varieties of sulphonamides or similar, synthetic, non-antibiotic antibacterial agents.

  10. EGU's Early Career Scientists Network

    Science.gov (United States)

    Roberts Artal, L.; Rietbroek, R.

    2017-12-01

    The EGU encourages early career scientists (ECS) to become involved in interdisciplinary research in the Earth, planetary and space sciences, through sessions, social events and short courses at the annual General Assembly in April and throughout the year. Through division-level representatives, all ECS members can have direct input into matters of the division. A Union-wide representative, who sits on the EGU Council, ensures that ECS are heard at a higher level in the Union too. After a brief introduction as to how the network is organised and structured, this presentation will discuss how EGU ECS activities have been tailored to the needs of ECS members and how those needs have been identified. Reaching and communicating opportunities to ECS remains an ongoing challenge; they will be discussed in this presentation too, as well as some thoughts on how to make them more effective. Finally, the service offered to EGU ECS members would certainly benefit from building links and collaboration with other early career networks in the geosciences. This presentation will outline some of our efforts in that direction and the challenges that remain.

    2012-04-01

    The objectives of this study were to: (1) calculate age-specific and age-adjusted cause-specific mortality rates for Arab Americans; and (2) compare these rates with those for blacks and whites. Mortality rates were estimated using Michigan death certificate data, an Arab surname and first name list, and 2000 U.S. Census data. Age-specific rates, age-adjusted all-cause and cause-specific rates were calculated. Arab Americans (75+) had higher mortality rates than whites and blacks. Among men, all-cause and cause-specific mortality rates for Arab Americans were in the range of whites and blacks. However, Arab American men had lower mortality rates from cancer and chronic lower respiratory disease compared to both whites and blacks. Among women, Arab Americans had lower mortality rates from heart disease, cancer, stroke, and diabetes than whites and blacks. Arab Americans are growing in number. Future study should focus on designing rigorous separate analyses for this population.

    Full Text Available The purpose of this study was to investigate gifted students’ images of scientists. The study involved 25 students in grades 7 and 8. The Draw-a-Scientist Test (DAST (Chamber, 183 was used to collect data. Drawings were eval-uated using certain criterion such as a scien-tist’s appearance and investigation, knowledge and technology symbols and gender and working style, place work, expressions, titles-captions-symbols and alternative images and age. The results showed that gifted students’ perceptions about scientists were stereotypical, generally with glasses and laboratory coats and working with experiment tubes, beakers indoors and using books, technological tools and dominantly lonely males. Most gifted stu-dents drew male scientists. Although females drew male scientists, none of the boys drew female scientist.

  15. Environmental status of the Lake Michigan region. Volume 3. Chemistry of Lake Michigan

    Energy Technology Data Exchange (ETDEWEB)

    Torrey, M S

    1976-05-01

    The report is a synoptic review of data collected over the past twenty years on the chemistry of Lake Michigan. Changes in water quality and sediment chemistry, attributable to cultural and natural influences, are considered in relation to interacting processes and factors controlling the distribution and concentration of chemical substances within the Lake. Temperature, light, and mixing processes are among the important natural influences that affect nutrient cycling, dispersal of pollutants, and fate of materials entering the Lake. Characterization of inshore-offshore and longitudinal differences in chemical concentrations and sediment chemistry for the main body of the Lake is supplemented by discussion of specific areas such as Green Bay and Grand Traverse Bay. Residues, specific conductance, dissolved oxygen, major and trace nutrients, and contaminants are described in the following context: biological essentiality and/or toxicity, sources to the Lake, concentrations in the water column and sediments, chemical forms, seasonal variations and variation with depth. A summary of existing water quality standards, statutes, and criteria applicable to Lake Michigan is appended.

    Wallace, G.J.

    1977-07-01

    This report characterizes the bird life found in 100 counties of the four states peripheral to Lake Michigan. It discusses major habitats (the Lake Michigan shoreline, inland lakes, rivers and streams, marshes, fields and open spaces, and woodlots) and associates specific birds with habitats according to preferences for space and food. It also discusses the special attributes of state parks and lakeshores, refuges and sanctuaries, and other special areas which are attractive to avifauna. Patterns of historical occurrence and abundance, and the influence of pesticides and pollution, disease, and hunting pressure are explored to place present occurrence in a modern perspective. Migration patterns are discussed to explain increases and decreases which occur in nonresident avifauna of the Basin. The distribution and habits of birds that occur regularly in the Basin are described in an annotated list; a more complete list is presented in a table which encapsulates data for rapid and convenient reference. Separate sections deal with extinct, extirpated, and introduced species, and with endangered, threatened, and declining species.

  19. Flood of April 1975 at Williamston, Michigan

    Science.gov (United States)

    Knutilla, R.L.; Swallow, L.A.

    1975-01-01

    On April 18 between 5 p.m. and 12 p.m. the city of Williamston experienced an intense rain storm that caused the Red Cedar River and the many small streams in the area to overflow their banks and resulted in the most devastating flood since at least 1904. Local officials estimated a loss of \\$775,000 in property damage. Damage from flooding by the Red Cedar River was caused primarily by inundation, rather than by water moving at high velocity, as is common when many streams are flooded. During the flood of April 1975 many basements were flooded as well as the lower floors of some homes in the flood plain. Additional damage occurred in places when sewers backed up and flooded basements, and when ground water seeped through basement walls and floors—situations that affected many homes including those that were well outside of the flood plain.During the time of flooding the U.S. Geological Survey obtained aerial photography and data on a streamflow to document the disaster. This report shows on a photomosaic base map the extent of flooding along the Red Cedar River at Williamston, during the flood. It also presents data obtained at stream-gaging stations near Williamston, as well as the results of peak-flow discharge measurements made on the Red Cedar River at Michigan State Highway M-52 east of the city. Information on the magnitude of the flood can guide in making decisions pertaining to the use of flood-plains in the area. It is one of a series of reports on the April 1975 flood in the Lansing metropolitan area.

    2010-08-01

    During the International Year of Astronomy, Pacific Science Center is hosting a photography exhibit: Scientists Like Me: Faces of Discovery. The exhibit contains photographs of real, current astronomers and scientists working in astronomy and aerospace-related fields from many races, genders, cultural affiliations and walks of life. The photographs were taken and posters designed by Alyssa Trinh and Sarah Culp, high school interns in Discovery Corps, Pacific Science Center's youth development program. The direct contact between the scientists and the interns helps the intended audience of teachers and families personally connect with scientists. The finished posters from this exhibit are available online (http://pacificsciencecenter.org/scientists) for teachers to use in their classrooms, in addition to being displayed at Pacific Science Center and becoming part of Pacific Science Center's permanent art rotation. The objective of this project was to fill a need for representative photographs of scientists in the world community. It also met two of the goals of International Year of Astronomy: to provide a modern image of science and scientists, and to improve the gender-balanced representation of scientists at all levels and promote greater involvement by all people in scientific and engineering careers. We would like to build on the success of this project and create an annual summer internship, with different interns, focusing on creating posters for different fields of science.

    While some planetary scientists have extensive experience sharing their science with audiences, many can benefit from guidance on giving presentations or conducting activities for students. The Lunar and Planetary Institute (LPI) provides resources and trainings to support planetary scientists in their communication efforts. Trainings have included sessions for students and early career scientists at conferences (providing opportunities for them to practice their delivery and receive feedback for their poster and oral presentations), as well as separate communication workshops on how to engage various audiences. LPI has similarly begun coaching planetary scientists to help them prepare their public presentations. LPI is also helping to connect different audiences and their requests for speakers to planetary scientists. Scientists have been key contributors in developing and conducting activities in LPI education and public events. LPI is currently working with scientists to identify and redesign short planetary science activities for scientists to use with different audiences. The activities will be tied to fundamental planetary science concepts, with basic materials and simple modifications to engage different ages and audience size and background. Input from the planetary science community on these efforts is welcome. Current results and resources, as well as future opportunities will be shared.

  12. Code of conduct for scientists (abstract)

    Khurshid, S.J.

    2011-01-01

    The emergence of advanced technologies in the last three decades and extraordinary progress in our knowledge on the basic Physical, Chemical and Biological properties of living matter has offered tremendous benefits to human beings but simultaneously highlighted the need of higher awareness and responsibility by the scientists of 21 century. Scientist is not born with ethics, nor science is ethically neutral, but there are ethical dimensions to scientific work. There is need to evolve an appropriate Code of Conduct for scientist particularly working in every field of Science. However, while considering the contents, promulgation and adaptation of Codes of Conduct for Scientists, a balance is needed to be maintained between freedom of scientists and at the same time some binding on them in the form of Code of Conducts. The use of good and safe laboratory procedures, whether, codified by law or by common practice must also be considered as part of the moral duties of scientists. It is internationally agreed that a general Code of Conduct can't be formulated for all the scientists universally, but there should be a set of 'building blocks' aimed at establishing the Code of Conduct for Scientists either as individual researcher or responsible for direction, evaluation, monitoring of scientific activities at the institutional or organizational level.

    2015-05-01

    In the title of this paper, we have changed the slogan of the International Year of Astronomy, ``The Universe yours to discover" to ``The Universe for all to discover" in order to emphasize the need to think about broader audiences when we plan astronomical activities at school or during outreach events. The strategy we propose follows what is known as the Universal Design for Learning (UDL). UDL allows to reach to the general public as well as to audiences which might be regarded as ``special" because they have some disability. It has been shown that everybody has a preferred style of learning (some remember better what they see, others what they hear or what they touch) and therefore, everybody is more or less able under the different styles of learning. Through this talk I am going to outline some of the principles of the UDL that can be applied in the teaching and communication of Astronomy, along with an example of its implementation in the project ``A Touch of the Universe".

  16. Discovering context-aware conditional functional dependencies

    Institute of Scientific and Technical Information of China (English)

    Yuefeng DU; Derong SHEN; Tiezheng NIE; Yue KOU; Ge YU

    2017-01-01

    Conditional functional dependencies(CFDs) are important techniques for data consistency.However,CFDs are limited to 1) provide the reasonable values for consistency repairing and 2) detect potential errors.This paper presents context-aware conditional functional dependencies(CCFDs) which contribute to provide reasonable values and detect potential errors.Especially,we focus on automatically discovering minimal CCFDs.In this paper,we present context relativity to measure the relationship of CFDs.The overlap of the related CFDs can provide reasonable values which result in more accuracy consistency repairing,and some related CFDs are combined into CCFDs.Moreover,we prove that discovering minimal CCFDs is NP-complete and we design the precise method and the heuristic method.We also present the dominating value to facilitate the process in both the precise method and the heuristic method.Additionally,the context relativity of the CFDs affects the cleaning results.We will give an approximate threshold of context relativity according to data distribution for suggestion.The repairing results are approved more accuracy,even evidenced by our empirical evaluation.

    The Silurian-age Salina salt, one of the greatest deposits of bedded rock salt in the world, underlies most of the Michigan basin and parts of the Appalachian basin in Ohio. Pennsylvania, New York, and West Virginia. Interest in this salt deposit has increased in recent years because there may be one or more areas where it could be used safely as a repository for the underground storage of high-level radioactive wastes. The general geology of the Michigan basin is summarized and the major salt deposits are described in the hope that these data will be useful in determining whether there are any areas in the basin that are sufficiently promising to warrant further detailed study. Distribution of the important salt deposits in the basin is limited to the Southern Peninsula of Michigan

  18. A conceptual framework for Lake Michigan coastal/nearshore ecosystems, with application to Lake Michigan Lakewide Management Plan (LaMP) objectives

    Science.gov (United States)

    Seelbach, Paul W.; Fogarty, Lisa R.; Bunnell, David Bo; Haack, Sheridan K.; Rogers, Mark W.

    2013-01-01

    The Lakewide Management Plans (LaMPs) within the Great Lakes region are examples of broad-scale, collaborative resource-management efforts that require a sound ecosystems approach. Yet, the LaMP process is lacking a holistic framework that allows these individual actions to be planned and understood within the broader context of the Great Lakes ecosystem. In this paper we (1) introduce a conceptual framework that unifies ideas and language among Great Lakes managers and scientists, whose focus areas range from tributary watersheds to open-lake waters, and (2) illustrate how the framework can be used to outline the geomorphic, hydrologic biological, and societal processes that underlie several goals of the Lake Michigan LaMP, thus providing a holistic and fairly comprehensive roadmap for tackling these challenges. For each selected goal, we developed a matrix that identifies the key ecosystem processes within the cell for each lake zone and each discipline; we then provide one example where a process is poorly understood and a second where a process is understood, but its impact or importance is unclear. Implicit in these objectives was our intention to highlight the importance of the Great Lakes coastal/nearshore zone. Although the coastal/nearshore zone is the important linkage zone between the watershed and open-lake zones—and is the zone where most LaMP issues are focused--scientists and managers have a relatively poor understanding of how the coastal/nearshore zone functions. We envision follow-up steps including (1) collaborative development of a more detailed and more complete conceptual model of how (and where) identified processes are thought to function, and (2) a subsequent gap analysis of science and monitoring priorities.

  19. Fast-food consumption and obesity among Michigan adults.

    Anderson, Beth; Rafferty, Ann P; Lyon-Callo, Sarah; Fussman, Christopher; Imes, Gwendoline

    2011-07-01

    Consumption of meals eaten away from home, especially from fast-food restaurants, has increased in the United States since the 1970s. The main objective of this study was to examine the frequency and characteristics of fast-food consumption among adults in Michigan and obesity prevalence. We analyzed data from 12 questions about fast-food consumption that were included on the 2005 Michigan Behavioral Risk Factor Survey, a population-based telephone survey of Michigan adults, using univariate and bivariate analyses and multivariate logistic regression, and compared these data with data on Michigan obesity prevalence. Approximately 80% of Michigan adults went to fast-food restaurants at least once per month and 28% went regularly (≥2 times/wk). Regular fast-food consumption was higher among younger adults (mostly men) but was not significantly associated with household income, education, race, or urbanicity (in a multivariate framework). The prevalence of obesity increased consistently with frequenting fast-food restaurants, from 24% of those going less than once a week to 33% of those going 3 or more times per week. The predominant reason for choosing fast food was convenience. Although hypothetically 68% of adults who go to fast-food restaurants would choose healthier fast-food items when available, only 16% said they ever use nutritional information when ordering. The prevalence of fast-food consumption is high in Michigan across education, income, and racial groups and is strongly associated with obesity. Making nutritional information at fast-food restaurants more readily available and easier to use may help consumers to order more healthful or lower-calorie items.

    The authors present some HR diagrams constructed using data from the Michigan Spectral Catalogues. Houk (1975) has been systematically reclassifying the Henry Draper stars on the MK system, from the south pole northward. Objective-prism plates, with a reciprocal dispersion of 108 A/mm, have been taken with the Michigan Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory in Chile. The spectra are classified visually from the plates, and the results are put onto IBM cards and magnetic tape from which the catalogues are produced. (Auth.)

  4. Michigan Health & Hospital Association Keystone Obstetrics: a statewide collaborative for perinatal patient safety in Michigan.

    2011-12-01

    Preventable harm to mothers and infants during labor and birth is a significant patient safety and professional liability issue. A Michigan Health & Hospital Association Keystone Center for Patient Safety & Quality Obstetric Collaborative Project involved perinatal teams from 15 Michigan hospitals during an 11-month period in 2009. The purpose of the project was to promote safe care practices during labor and birth using the Comprehensive Unit-based Safety Program (CUSP). Consistent with the CUSP model, this project's components included assessing and promoting a culture of safety; interdisciplinary team building; case review; learning from defects through multiple methods of education; team and individual coaching and peer encouragement; administrative support for the establishment of a fundamental safety infrastructure; and ongoing evaluation of care processes and outcomes. Study measures included 32 components of a perinatal patient infrastructure, 6 care processes during labor and birth, and 4 neonatal outcomes. Significant improvements were found in the safety culture (Safety Attitudes Questionnaire), the perinatal patient safety infrastructure components, and all care processes. Although the project was successful, getting buy-in from all members of the clinical team in each hospital for all of the measures was challenging at times. There was initial resistance to some of the measures and their various expected aspects of care. For example, some of the clinicians were initially reluctant to adopt the recommended standardized oxytocin protocol. Peer encouragement and unit-based feedback on progress in minimizing early elective births proved useful in many hospitals. A CUSP in obstetrics can be beneficial in improving the care of mothers and infants during labor and birth.

  5. The Reputational Consequences of Failed Replications and Wrongness Admission among Scientists.

    Full Text Available Scientists are dedicating more attention to replication efforts. While the scientific utility of replications is unquestionable, the impact of failed replication efforts and the discussions surrounding them deserve more attention. Specifically, the debates about failed replications on social media have led to worry, in some scientists, regarding reputation. In order to gain data-informed insights into these issues, we collected data from 281 published scientists. We assessed whether scientists overestimate the negative reputational effects of a failed replication in a scenario-based study. Second, we assessed the reputational consequences of admitting wrongness (versus not as an original scientist of an effect that has failed to replicate. Our data suggests that scientists overestimate the negative reputational impact of a hypothetical failed replication effort. We also show that admitting wrongness about a non-replicated finding is less harmful to one's reputation than not admitting. Finally, we discovered a hint of evidence that feelings about the replication movement can be affected by whether replication efforts are aimed one's own work versus the work of another. Given these findings, we then present potential ways forward in these discussions.

    Jensen, Mikael Rune; Holmgren, Thomas; Pedersen, Torben Bach

    2004-01-01

    On-Line Analytical Processing (OLAP) systems based on multidimensional databases are essential elements of decision support. However, most existing data is stored in “ordinary” relational OLTP databases, i.e., data has to be (re-) modeled as multidimensional cubes before the advantages of OLAP to...... algorithms for discovering multidimensional schemas from relational databases. The algorithms take a wide range of available metadata into account in the discovery process, including functional and inclusion dependencies, and key and cardinality information....... tools are available. In this paper we present an approach for the automatic construction of multidimensional OLAP database schemas from existing relational OLTP databases, enabling easy OLAP design and analysis for most existing data sources. This is achieved through a set of practical and effective...

  8. Discovering new information in bibliographic databases

    Directory of Open Access Journals (Sweden)

    Emil Hudomalj

    2005-01-01

    Full Text Available Databases contain information that can usually not be revealed by standard query systems. For that purpose, the methods for knowledge discovery from databases can be applied, which enable the user to browse aggregated data, discover trends, produce online reports, explore possible new associations within the data etc. Such methods are successfully employed in various fields, such as banking, insurance and telecommunications, while they are seldom used in libraries. The article reviews the development of query systems for bibliographic databases, including some early attempts to apply modern knowledge discovery methods. Analytical databases are described in more detail, since they usually serve as the basis for knowledge discovery. Data mining approaches are presented, since they are a central step in the knowledge discovery process. The key role of librarians who can play a key part in developing systems for finding new information in existing bibliographic databases is stressed.

  9. Michael Maier--nine newly discovered letters.

    Lenke, Nils; Roudet, Nicolas; Tilton, Hereward

    2014-02-01

    The authors provide a transcription, translation, and evaluation of nine newly discovered letters from the alchemist Michael Maier (1568-1622) to Gebhardt Johann von Alvensleben (1576-1631), a noble landholder in the vicinity of Magdeburg. Stemming from the final year of his life, this correspondence casts new light on Maier's biography, detailing his efforts to secure patronage amid the financial crisis of the early Thirty Years' War. While his ill-fated quest to perfect potable gold continued to form the central focus of his patronage suits, Maier also offered his services in several arts that he had condemned in his printed works, namely astrology and "supernatural" magic. Remarks concerning his previously unknown acquaintance with Heinrich Khunrath call for a re-evaluation of Maier's negotiation of the discursive boundaries between Lutheran orthodoxy and Paracelsianism. The letters also reveal Maier's substantial contribution to a work previously ascribed solely to the English alchemist Francis Anthony.

  10. Discovering network behind infectious disease outbreak

    Science.gov (United States)

    Maeno, Yoshiharu

    2010-11-01

    Stochasticity and spatial heterogeneity are of great interest recently in studying the spread of an infectious disease. The presented method solves an inverse problem to discover the effectively decisive topology of a heterogeneous network and reveal the transmission parameters which govern the stochastic spreads over the network from a dataset on an infectious disease outbreak in the early growth phase. Populations in a combination of epidemiological compartment models and a meta-population network model are described by stochastic differential equations. Probability density functions are derived from the equations and used for the maximal likelihood estimation of the topology and parameters. The method is tested with computationally synthesized datasets and the WHO dataset on the SARS outbreak.

    2013-04-04

    Pancreatic sarcoidosis is a rare variant of systemic sarcoidosis, with cases described in literature as recently as January 2010. We present here a case of pancreatic involvement with non-caseating granulomas discovered on laparotomy in a patient with a preoperative diagnosis of pancreatic carcinoma. Computer tomography scan without contrast revealed a well-marginated smooth-shaped tumor in the head of the pancreas morphologically consistent with malignancy. During Whipple procedure, the mass was found to be a large lymph node that contained numerous non-caseating granulomas. Radiologically and clinically, non-caseating granulomas of the pancreas are often misdiagnosed as malignant tumor. Special attention given to this differential diagnosis by surgeons, pathologists and clinicians can avoid misdiagnosis and unnecessary treatment.

  13. Discovering Sentinel Rules for Business Intelligence

    Science.gov (United States)

    Middelfart, Morten; Pedersen, Torben Bach

    This paper proposes the concept of sentinel rules for multi-dimensional data that warns users when measure data concerning the external environment changes. For instance, a surge in negative blogging about a company could trigger a sentinel rule warning that revenue will decrease within two months, so a new course of action can be taken. Hereby, we expand the window of opportunity for organizations and facilitate successful navigation even though the world behaves chaotically. Since sentinel rules are at the schema level as opposed to the data level, and operate on data changes as opposed to absolute data values, we are able to discover strong and useful sentinel rules that would otherwise be hidden when using sequential pattern mining or correlation techniques. We present a method for sentinel rule discovery and an implementation of this method that scales linearly on large data volumes.

  14. The discovery of nuclear fission and the responsibility of the scientist

    International Nuclear Information System (INIS)

    Staab, H.A.

    1989-01-01

    The history of the discovery of nuclear fission is placed in historical context and the responsibility of the scientists involved for the subsequent military uses is discussed. It is explained that the deep things in science are not found because they are useful; they are found because it is possible to find them. If Otto Hahn and his co-workers had not discovered nuclear fission someone else in the late 1930s or early 1940s would have done so. It was decisions outside science which set the course for the nuclear fission research once the basic principle had been understood. The question how far does the scientists responsibility extend for unknown and unintended consequences of research and for misuses of his findings by others is discussed. Scientists have a duty to understand the applications of their work and to warn of misuse or hazards, as did Otto Hahn. (UK)

    2000-01-01

    The year 2000 marks the hundredth anniversary of the birth of Frederic Joliot-Curie, who can be safely termed as one of the most prominent figures of the twentieth century. The scientist and his wife Irene discovered artificial radioactivity at the Radium Institute; in 1935, they received the Nobel Chemistry Prize for their discovery. At the College de France four years later, Frederic Joliot-Curie uncovered the conditions required for a chain reaction in uranium. He gave meaning to the word civic-minded citizen. His many deeds were a statement that a scientist should offer more than his research and its possible applications to society; that he should not shrink from committing to political and social struggles. That is why this exceptional man is a model of a committed scientist. (author)

    Harvard Business Review recently named the data scientist described as a high-ranking professional with the training and curiosity to make discoveries in the world of Big Data as "the sexiest job of the 21st century." Librarians and information professionals have always worked with data in order to meet the information needs of their constituents, thus "Big Data" is not a new concept for them though it is spawning new approaches along with a language all its own. InThe Accidental Data Scientist, Amy Affelt shows information professionals how to leverage their skills and training to master emerging tools, techniques, and vocabulary; create mission-critical Big Data research deliverables; and discover rewarding new career opportunities by embracing their inner Data Scientist.

  5. A post-Calumet shoreline along southern Lake Michigan

    Science.gov (United States)

    Capps, D.K.; Thompson, T.A.; Booth, R.K.

    2007-01-01

    The southern shore of Lake Michigan is the type area for many of ancestral Lake Michigan's late Pleistocene lake phases, but coastal deposits and features of the Algonquin phase of northern Lake Michigan, Lake Huron, and Lake Superior are not recognized in the area. Isostatic rebound models suggest that Algonquin phase deposits should be 100 m or more below modern lake level. A relict shoreline, however, exists along the lakeward margin of the Calumet Beach that was erosional west of Deep River and depositional east of the river. For this post-Calumet shoreline, the elevation of basal foreshore deposits east of Deep River and the base of the scarp west of Deep River indicate a slightly westward dipping water plane that is centered at ???184 m above mean sea level. Basal foreshore elevations also indicate that lake level fell ???2 m during the development of the shoreline. The pooled mean of radiocarbon dates from the surface of the peat below post-Calumet shoreline foreshore deposits indicate that the lake transgressed over the peat at 10,560 ?? 70 years B.P. Pollen assemblages from the peat are consistent with this age. The elevation and age of the post-Calumet shoreline are similar to the Main Algonquin phase of Lake Huron. Recent isostatic rebound models do not adequately address a high-elevation Algonquin-age shoreline along the southern shore of Lake Michigan, but the Goldthwait (1908) hinge-line model does. ?? 2006 Springer Science+Business Media B.V.

    2013-06-01

    Full Text Available The purpose of this study was to create a norm reference of current grip and pinch strength norms for working-age Michigan adults. This normative study included a convenience sample of 179 volunteers who were employees at car plants in South East Michigan or hospital sites in West Michigan. Participants’ ages ranged from between 20 and 62 years of age with a mean age of 49.15 years. There were 78 females (44% and 101 males (56%. Subjects were classified by gender and in the age categories of ages 20 to 49 years and ages 50-62 years. Grip and pinch strength norms were collected following the American Society of Hand Therapy protocol. The norms from these working adults were calculated with descriptive statistics for males and females in two age classifications: ages 20 to 49 and ages 50 to 62 years. Standard Errors (SE are better than the 1985 norms for both males and females ages 20 to 49 years. SEs are higher than the ages 20 to 49 years’ norms for the ages 50 to 62 years age categories in both males and females. These norms offer a point of comparison for clinicians to use for clients in Michigan who are ages 20 to 62 years and who have a goal to improve their grip strength. Clients’ grip and pinch strength could be compared to their age level or gender norms using the comparison for one standard deviation above, below, or at the means.

    Carl Sagan set an example to all scientists when he encouraged us to reach out to the public and share the excitement of discovery and exploration. The prejudice that ensued did not deter Sagan and, with the passing of years, more and more scientists have followed his example. Although at present scientists at all ranks are encouraged by their institutions to do outreach, the balancing of a successful scientific career with teaching and outreach is often not an easy one. Young scientists, in particular, may worry about how their outreach efforts are viewed in the community and how they will find the time and energy for these efforts. This talk will offer suggestions on how to balance an active science research program with outreach activities, the many different ways to engage in education and public outreach, and how the rewards are truly priceless.

  2. Elements of ethics for physical scientists

    CERN Document Server

    Greer, Sandra C

    2017-01-01

    This book offers the first comprehensive guide to ethics for physical scientists and engineers who conduct research. Written by a distinguished professor of chemistry and chemical engineering, the book focuses on the everyday decisions about right and wrong faced by scientists as they do research, interact with other people, and work within society. The goal is to nurture readers’ ethical intelligence so that they know an ethical issue when they see one, and to give them a way to think about ethical problems. After introductions to the philosophy of ethics and the philosophy of science, the book discusses research integrity, with a unique emphasis on how scientists make mistakes and how they can avoid them. It goes on to cover personal interactions among scientists, including authorship, collaborators, predecessors, reviewers, grantees, mentors, and whistle-blowers. It considers underrepresented groups in science as an ethical issue that matters not only to those groups but also to the development of scien...

    OpenAIRE

    Riesch, H.

    2008-01-01

    Many studies in public understanding of science emphasise that learning how to do science also involves learning about the philosophical issues surrounding the nature of science. This thesis aims to find out how scientists themselves talk and write about these philosophical topics, and how these topics get used in scientific thought. It contrasts scientists' opinions on these issues with how they are portrayed in popular science, and also contrasts them with how philosophers themselves have j...

  15. Analyzing prospective teachers' images of scientists using positive, negative and stereotypical images of scientists

    2013-04-01

    Background and purpose : This study details the use of a conceptual framework to analyze prospective teachers' images of scientists to reveal their context-specific conceptions of scientists. The conceptual framework consists of context-specific conceptions related to positive, stereotypical and negative images of scientists as detailed in the literature on the images, role and work of scientists. Sample, design and method : One hundred and ninety-six drawings of scientists, generated by prospective teachers, were analyzed using the Draw-A-Scientist-Test Checklist (DAST-C), a binary linear regression and the conceptual framework. Results : The results of the binary linear regression analysis revealed a statistically significant difference for two DAST-C elements: ethnicity differences with regard to drawing a scientist who was Caucasian and gender differences for indications of danger. Analysis using the conceptual framework helped to categorize the same drawings into positive, stereotypical, negative and composite images of a scientist. Conclusions : The conceptual framework revealed that drawings were focused on the physical appearance of the scientist, and to a lesser extent on the equipment, location and science-related practices that provided the context of a scientist's role and work. Implications for teacher educators include the need to understand that there is a need to provide tools, like the conceptual framework used in this study, to help prospective teachers to confront and engage with their multidimensional perspectives of scientists in light of the current trends on perceiving and valuing scientists. In addition, teacher educators need to use the conceptual framework, which yields qualitative perspectives about drawings, together with the DAST-C, which yields quantitative measure for drawings, to help prospective teachers to gain a holistic outlook on their drawings of scientists.

  16. CORNELL: CLEO discovers B meson penguins

    1993-01-01

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

  17. Discovering Alzheimer Genetic Biomarkers Using Bayesian Networks

    Fayroz F. Sherif

    2015-01-01

    Full Text Available Single nucleotide polymorphisms (SNPs contribute most of the genetic variation to the human genome. SNPs associate with many complex and common diseases like Alzheimer’s disease (AD. Discovering SNP biomarkers at different loci can improve early diagnosis and treatment of these diseases. Bayesian network provides a comprehensible and modular framework for representing interactions between genes or single SNPs. Here, different Bayesian network structure learning algorithms have been applied in whole genome sequencing (WGS data for detecting the causal AD SNPs and gene-SNP interactions. We focused on polymorphisms in the top ten genes associated with AD and identified by genome-wide association (GWA studies. New SNP biomarkers were observed to be significantly associated with Alzheimer’s disease. These SNPs are rs7530069, rs113464261, rs114506298, rs73504429, rs7929589, rs76306710, and rs668134. The obtained results demonstrated the effectiveness of using BN for identifying AD causal SNPs with acceptable accuracy. The results guarantee that the SNP set detected by Markov blanket based methods has a strong association with AD disease and achieves better performance than both naïve Bayes and tree augmented naïve Bayes. Minimal augmented Markov blanket reaches accuracy of 66.13% and sensitivity of 88.87% versus 61.58% and 59.43% in naïve Bayes, respectively.

    The AGU fall meeting is a time for scientists to share what we have been hard at work on for the past year, to share our trials and tribulations, and of course, to share our science (we hope inspirational). In addition to sharing, the AGU fall meeting is also about collaboration as it brings old and new colleagues together from diverse communities across the planet. By sharing our ideas and findings, we build new relationships with the potential to cross boundaries and solve complex and pressing environmental issues. With ever emerging and intensifying water scarcity, extreme weather, and water quality issues across the plant, it is especially important that scientists like us share our ideas and work together to put these ideas into action. My vision of the future of water sciences embraces this fact. I believe that better training is needed to help early career scientists, like myself, build connections within and outside of our fields. First and foremost, more advanced training in effective storytelling concepts and themes may improve our ability to provide context for our research. Second, training in the production of video for internet-based media (e.g. YouTube) may help us bring our research to audiences in a more personalized way. Third, opportunities to practice presenting at highly visible public events such as the AGU fall meeting, will serve to prepare early career scientists for a variety of audiences. We hope this session, ';Water Sciences Pop-Ups', will provide the first steps to encourage and train early career scientists as they share and collaborate with scientists and non-scientists around the world.

  1. Discovering biological progression underlying microarray samples.

    Directory of Open Access Journals (Sweden)

    Peng Qiu

    2011-04-01

    Full Text Available In biological systems that undergo processes such as differentiation, a clear concept of progression exists. We present a novel computational approach, called Sample Progression Discovery (SPD, to discover patterns of biological progression underlying microarray gene expression data. SPD assumes that individual samples of a microarray dataset are related by an unknown biological process (i.e., differentiation, development, cell cycle, disease progression, and that each sample represents one unknown point along the progression of that process. SPD aims to organize the samples in a manner that reveals the underlying progression and to simultaneously identify subsets of genes that are responsible for that progression. We demonstrate the performance of SPD on a variety of microarray datasets that were generated by sampling a biological process at different points along its progression, without providing SPD any information of the underlying process. When applied to a cell cycle time series microarray dataset, SPD was not provided any prior knowledge of samples' time order or of which genes are cell-cycle regulated, yet SPD recovered the correct time order and identified many genes that have been associated with the cell cycle. When applied to B-cell differentiation data, SPD recovered the correct order of stages of normal B-cell differentiation and the linkage between preB-ALL tumor cells with their cell origin preB. When applied to mouse embryonic stem cell differentiation data, SPD uncovered a landscape of ESC differentiation into various lineages and genes that represent both generic and lineage specific processes. When applied to a prostate cancer microarray dataset, SPD identified gene modules that reflect a progression consistent with disease stages. SPD may be best viewed as a novel tool for synthesizing biological hypotheses because it provides a likely biological progression underlying a microarray dataset and, perhaps more importantly, the

    We present 20 Wide-field Infrared Survey Explorer (WISE)-selected galaxies with bolometric luminosities L{sub bol} > 10{sup 14} L{sub ☉}, including five with infrared luminosities L{sub IR} ≡ L{sub (rest} {sub 8–1000} {sub μm)} > 10{sup 14} L{sub ☉}. These “extremely luminous infrared galaxies,” or ELIRGs, were discovered using the “W1W2-dropout” selection criteria which requires marginal or non-detections at 3.4 and 4.6 μm (W1 and W2, respectively) but strong detections at 12 and 22 μm in the WISE survey. Their spectral energy distributions are dominated by emission at rest-frame 4–10 μm, suggesting that hot dust with T{sub d} ∼ 450 K is responsible for the high luminosities. These galaxies are likely powered by highly obscured active galactic nuclei (AGNs), and there is no evidence suggesting these systems are beamed or lensed. We compare this WISE-selected sample with 116 optically selected quasars that reach the same L{sub bol} level, corresponding to the most luminous unobscured quasars in the literature. We find that the rest-frame 5.8 and 7.8 μm luminosities of the WISE-selected ELIRGs can be 30%–80% higher than that of the unobscured quasars. The existence of AGNs with L{sub bol} > 10{sup 14} L{sub ☉} at z > 3 suggests that these supermassive black holes are born with large mass, or have very rapid mass assembly. For black hole seed masses ∼10{sup 3} M{sub ☉}, either sustained super-Eddington accretion is needed, or the radiative efficiency must be <15%, implying a black hole with slow spin, possibly due to chaotic accretion.

  3. ROSAT Discovers Unique, Distant Cluster of Galaxies

    1995-06-01

    Brightest X-ray Cluster Acts as Strong Gravitational Lens Based on exciting new data obtained with the ROSAT X-ray satellite and a ground-based telescope at the ESO La Silla Observatory, a team of European astronomers [2] has just discovered a very distant cluster of galaxies with unique properties. It emits the strongest X-ray emission of any cluster ever observed by ROSAT and is accompanied by two extraordinarily luminous arcs that represent the gravitationally deflected images of even more distant objects. The combination of these unusual characteristics makes this cluster, now known as RXJ1347.5-1145, a most interesting object for further cosmological studies. DISCOVERY AND FOLLOW-UP OBSERVATIONS This strange cluster of galaxies was discovered during the All Sky Survey with the ROSAT X-ray satellite as a moderately intense X-ray source in the constellation of Virgo. It could not be identified with any already known object and additional ground-based observations were therefore soon after performed with the Max-Planck-Society/ESO 2.2-metre telescope at the La Silla observatory in Chile. These observations took place within a large--scale redshift survey of X-ray clusters of galaxies detected by the ROSAT All Sky Survey, a so-called ``ESO Key Programme'' led by astronomers from the Max-Planck-Institut fur Extraterrestrische Physik and the Osservatorio Astronomico di Brera. The main aim of this programme is to identify cluster X-ray sources, to determine the distance to the X-ray emitting clusters and to investigate their overall properties. These observations permitted to measure the redshift of the RXJ1347.5-1145 cluster as z = 0.45, i.e. it moves away from us with a velocity (about 106,000 km/sec) equal to about one-third of the velocity of light. This is an effect of the general expansion of the universe and it allows to determine the distance as about 5,000 million light-years (assuming a Hubble constant of 75 km/sec/Mpc). In other words, we see these

    Physician scientists are seen as important in healthcare research. However, the number of physician scientists and their success in obtaining NIH funding have been declining for many years. The shortage of physician scientists in Physical Medicine and Rehabilitation is particularly severe, and can be attributed to many of the same factors that affect physician scientists in general, as well as to the lack of well developed models for research training. In 1995, the Rehabilitation Medicine Scientist Training Program (RMSTP) was funded by a K12 grant from the National Center of Medical Rehabilitation Research (NCMRR), as one strategy for increasing the number of research-productive physiatrists. The RMSTP's structure was revised in 2001 to improve the level of preparation of incoming trainees, and to provide a stronger central mentorship support network. Here we describe the original and revised structure of the RMSTP and review subjective and objective data on the productivity of the trainees who have completed the program. These data suggest that RMSTP trainees are, in general, successful in obtaining and maintaining academic faculty positions and that the productivity of the cohort trained after the revision, in particular, shows impressive growth after about 3 years of training.

    Assessment of researchers is necessary for decisions of hiring, promotion, and tenure. A burgeoning number of scientific leaders believe the current system of faculty incentives and rewards is misaligned with the needs of society and disconnected from the evidence about the causes of the reproducibility crisis and suboptimal quality of the scientific publication record. To address this issue, particularly for the clinical and life sciences, we convened a 22-member expert panel workshop in Washington, DC, in January 2017. Twenty-two academic leaders, funders, and scientists participated in the meeting. As background for the meeting, we completed a selective literature review of 22 key documents critiquing the current incentive system. From each document, we extracted how the authors perceived the problems of assessing science and scientists, the unintended consequences of maintaining the status quo for assessing scientists, and details of their proposed solutions. The resulting table was used as a seed for participant discussion. This resulted in six principles for assessing scientists and associated research and policy implications. We hope the content of this paper will serve as a basis for establishing best practices and redesigning the current approaches to assessing scientists by the many players involved in that process.

    1992-01-01

    This paper reports that there is an urgent need for a large scale, nationwide education program designed to correct the almost ubiquitous misconceptions that exist because of the public's misinformation about commercial nuclear power. It is suggested that this program use only university professors and that it have a precisely defined target of community colleges. To do this a Distinguished Visiting Scientist Program needs to be established by the Department of Energy. This would be the means by which these visiting scientists could get invited for 2-day visits at community colleges. When on campus the visiting scientist would give lectures in the morning and it the afternoon to student and professors on just two topics dealing with commercial nuclear power: nuclear plants and disposal of the waste. It is suggested that a pilot program be done in California and selected hub-centers, and that it be evaluated by an independent agency so that it can be improved

    Fusion scientists have raised their voices to let the Department of Energy know that they are concerned about the DOE's commitment to fusion research. In a letter dated February 28, 1994, 37 scientists from 21 institutions noted that open-quotes US funding for fusion has steadily decreased: It is now roughly half its level of 1980. This peculiar and painful circumstance has forced the program to contract drastically, losing skilled technical personnel, even as it faces its most exciting opportunities.close quotes The letter was addressed to Martha Krebs, the DOE's director of the Office of Energy Research, and N. Anne Davies, associated director for fusion energy. The scientists wanted to make two points. The first was that fusion energy research, only midway between concept and commercialization, deserves major reinvestment. The second was that basic scientific knowledge in the area of fusion, not just applied engineering, must remain a priority

  13. The Normative Orientations of Climate Scientists.

    2017-10-01

    In 1942 Robert K. Merton tried to demonstrate the structure of the normative system of science by specifying the norms that characterized it. The norms were assigned the abbreviation CUDOs: Communism, Universalism, Disinterestedness, and Organized skepticism. Using the results of an on-line survey of climate scientists concerning the norms of science, this paper explores the climate scientists' subscription to these norms. The data suggests that while Merton's CUDOs remain the overall guiding moral principles, they are not fully endorsed or present in the conduct of climate scientists: there is a tendency to withhold results until publication, there is the intention of maintaining property rights, there is external influence defining research and the tendency to assign the significance of authored work according to the status of the author rather than content of the paper. These are contrary to the norms of science as proposed by Robert K. Merton.

    The questions confronting environmental managers responsible for the Great Lakes are complex and regulatory action (or inaction) have major social, environmental and economical consequences. It has become evident that rational approaches must be found to address the issues, more clearly identify and quantitate problems, locate and quantitate sources of important chemicals, and arrive at optimal remedial programs. A scientifically based management framework has been implemented and prototyped within the Great Lakes community of mangers and scientists referred to as the Mass Balance Approach. The US Environmental Protection Agency, led by the Great Lakes National Program Office (GLNPO) in cooperation with Office of Research and Development (ORD) and other state and academic organizations, has completed an intensive study of Green Bay (Lake Michigan) to test the feasibility of using the mass balance approach for managing toxic substances in the Great Lakes. This presentation will provide an overview of the project and the results. Conclusions and recommendations will be reviewed and implications for future policy based, scientific studies will be explored.

In April 2014, WNS was discovered in little brown bats ( Myotis lucifugus ) in Michigan, US, and has since been documented in 12 counties. Because current surveillance for WNS focuses primarily on mine-hibernating species in winter, it is subject to geographic, species, and seasonal bias. To investigate species affected and potential associations of gender, seasonal life cycle, and region with P. destructans prevalence, 1,040 rabies-negative bats were sampled from May 2014 to May 2015 from animals submitted as part of statewide rabies surveillance. The vast majority (96%) of the sample population consisted of big brown bats ( Eptesicus fuscus ), a noncavernicolous species. Two methods were used to detect P. destructans: fluorescence of the muzzle, wing, and tail membranes under ultraviolet light and PCR targeting genomic DNA on wing samples. Only five bats (0.5%), all M. lucifugus , were confirmed positive after nucleic acid sequencing of PCR amplicons. No other species were infected. All infected bats were collected from April to May, coinciding with their emergence from hibernation. As P. destructans and WNS spread westward, novel surveillance streams may provide a useful tool for wildlife management agencies seeking to detect the fungus where winter hibernacula such as caves and mines are absent or otherwise inaccessible.

  20. Media and the making of scientists

    O'Keeffe, Moira

    This dissertation explores how scientists and science students respond to fictional, visual media about science. I consider how scientists think about images of science in relation to their own career paths from childhood onwards. I am especially interested in the possibility that entertainment media can inspire young people to learn about science. Such inspiration is badly needed, as schools are failing to provide it. Science education in the United States is in a state of crisis. Studies repeatedly find low levels of science literacy in the U.S. This bleak situation exists during a boom in the popularity of science-oriented television shows and science fiction movies. How might entertainment media play a role in helping young people engage with science? To grapple with these questions, I interviewed a total of fifty scientists and students interested in science careers, representing a variety of scientific fields and demographic backgrounds, and with varying levels of interest in science fiction. Most respondents described becoming attracted to the sciences at a young age, and many were able to identify specific sources for this interest. The fact that interest in the sciences begins early in life, demonstrates a potentially important role for fictional media in the process of inspiration, perhaps especially for children without access to real-life scientists. One key aspect to the appeal of fiction about science is how scientists are portrayed as characters. Scientists from groups traditionally under-represented in the sciences often sought out fictional characters with whom they could identify, and viewers from all backgrounds preferred well-rounded characters to the extreme stereotypes of mad or dorky scientists. Genre is another aspect of appeal. Some respondents identified a specific role for science fiction: conveying a sense of wonder. Visual media introduce viewers to the beauty of science. Special effects, in particular, allow viewers to explore the

    sand and gravel also fill some of the valleys in the bedrock surface and yield moderate to large supplies of water. Production from public supply wells tapping the drift aquifers in the area ranges from about 50 to 1,200 gpm. The water from the drift aquifer is hard or very hard and commonly contains objectionable amounts of iron.The Saginaw formation is a source of water to wells supplying some of the small communities and industries in the county. The Saginaw, which is the uppermost bedrock formation in the area, underlies most of the county. It is composed of layers of sandstone, shale, and limestone and some beds of coal. The formation is composed principally of sandstone in some areas of the county, and shale in others. Production from wells tapping the Saginaw ranges from a few to about 500 gpm. The water produced is generally moderately hard or hard and commonly contains objectionable amounts of chloride. The quality of the water limits its development for water supply. Overdrafts from the Saginaw result in a lowering of the piezometric surface and commonly cause an upward migration of water high in chloride.The Michigan and Marshall formations are generally not sources of fresh water where they are overlain by the Saginaw formation. In the southern and eastern parts of the county where they are overlain by glacial deposits, they are a source of water of good quality. The quantity of water obtainable from these formations is not fully known. However, the Marshall may be a source of large supplies of water in the southeastern part of the county.An ample supply of water is available in lakes, ponds, and streams in the metropolitan area of Flint to meet requirements for domestic, sanitary, and firefighting use in civil defense emergencies. The extent of emergency use of water from these sources would depend upon the pumping, distribution, and treatment facilities available. Enough private industrial and commercial, and public wells are present in the area normally

    The Project Manager is one of the key individuals that can determine the success or failure of a project. NASA is fully committed to the training and development of Project Managers across the agency to ensure that highly capable individuals are equipped with the competencies and experience to successfully lead a project. An equally critical position is that of the Project Scientist. The Project Scientist provides the scientific leadership necessary for the scientific success of a project by insuring that the mission meets or exceeds the scientific requirements. Traditionally, NASA Goddard project scientists were appointed and approved by the Center Science Director based on their knowledge, experience, and other qualifications. However the process to obtain the necessary knowledge, skills and abilities was not documented or done in a systematic way. NASA Goddard's current Science Director, Nicholas White saw the need to create a pipeline for developing new projects scientists, and appointed a team to develop a process for training potential project scientists. The team members were Dr. Harley Thronson, Chair, Dr. Howard Kea, Mr. Mark Goldman, DACUM facilitator and the late Dr. Michael VanSteenberg. The DACUM process, an occupational analysis and evaluation system, was used to produce a picture of the project scientist's duties, tasks, knowledge, and skills. The output resulted in a 3-Day introductory course detailing all the required knowledge, skills and abilities a scientist must develop over time to be qualified for selections as a Project Scientist.

  4. Forensic scientists' conclusions: how readable are they for non-scientist report-users?

    Scientists have an ethical responsibility to assist non-scientists to understand their findings and expert opinions before they are used as decision-aids within the criminal justice system. The communication of scientific expert opinion to non-scientist audiences (e.g., police, lawyers, and judges) through expert reports is an important but under-researched issue. Readability statistics were used to assess 111 conclusions from a proficiency test in forensic glass analysis. The conclusions were written using an average of 23 words per sentence, and approximately half of the conclusions were expressed using the active voice. At an average Flesch-Kincaid Grade level of university undergraduate (Grade 13), and Flesch Reading Ease score of difficult (42), the conclusions were written at a level suitable for people with some tertiary education in science, suggesting that the intended non-scientist readers would find them difficult to read. To further analyse the readability of conclusions, descriptive features of text were used: text structure; sentence structure; vocabulary; elaboration; and coherence and unity. Descriptive analysis supported the finding that texts were written at a level difficult for non-scientists to read. Specific aspects of conclusions that may pose difficulties for non-scientists were located. Suggestions are included to assist scientists to write conclusions with increased readability for non-scientist readers, while retaining scientific integrity. In the next stage of research, the readability of expert reports in their entirety is to be explored. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    The stresses placed on Lake Michigan since the advent of industrialization require knowledge of the sedimentology of the whole lake in order to make informed decisions for environmental planning. Sediment accumulation rates are low: areas of the lake receiving the most sediment average only 1 mm a-1; deep-water basins average 0.1 to 0.5 mm a-1; and large areas are not receiving any sediment. Sediment was deposited rapidly (typically 5 mm a-1), in the form of rock flour, during the deglaciation of both Lake Michigan and Lake Superior Basins. Then the rate of accumulation decreased by 80-90% and has remained relatively constant since final deglaciation. Because active sedimentation occurs mostly in the deep water areas of the lake, the sediment remains undisturbed and contains a record of the chemical history of the lake. ?? 1983 Dr W. Junk Publishers.

    1976-01-01

    A comparison of data on fish mortalities due to impingement at thermal power plant water intakes on Lake Michigan with available estimates of standing crop biomass, commercial and sport fishery catches, and estimated predation mortality is presented. The striking features of these data are the proportions of total mortality due to predation and the lack of accurate basic population statistics such as standing crop biomass and natural mortality for important forage and human food fishes in Lake Michigan. Although this preliminary assessment would indicate that power plant and total impingement losses constitute an insignificant fraction of total forage biomass, the potentially unstable forage-predator ratios and the apparent high degree of annual fluctuations (year-classes) in alewife, smelt, and perch indicate the need for a more detailed assessment of cooling-system related impact on selected populations

  8. Acid rain stimulation of Lake Michigan phytoplankton growth

    1987-01-01

    Three laboratory experiments demonstrated that additions of rainwater to epilimnetic lake water collected in southeastern Lake Michigan stimulated chlorophyll a production more than did additions of reagent-grade water during incubations of 12 to 20 d. Chlorophyll a production did not begin until 3–5 d after the rain and lake water were mixed. The stimulation caused by additions of rain acidified to pH 3.0 was greater than that caused by additions of untreated rain (pH 4.0–4.5). Our results support the following hypotheses: (1) Acid rain stimulates the growth of phytoplankton in lake water; (2) phosphorus in rain appears to be the factor causing this stimulation. We conclude that acid rain may accelerate the growth of epilimnetic phytoplankton in Lake Michigan (and other similar lakes) during stratification when other sources of bioavailable phosphorus to the epilimnion are limited

    2011-12-01

    Full Text Available Microblogging services, in particular Twitter, have experienced an explosive uptake in the last few years with a decelerated grown rate since 2010. Apart from celebrities, PR and news agencies, the bulk of user profiles stems form private individuals. Amongst them, individual scientists have started to make use of Twitter for professional purposes. This paper presents a qualitative approach of discovering microblogging practices and obtaining rich descriptions of few cases that give a deeper insight into how Twitter is used by scientists active in the field of e-Learning and how this practice shapes their social networks. The methodological approach is based on online ethnographic studies. Therefore Grabeeter, a tool for collecting all public tweets of a person in various formats, has been adapted in order to obtain the data appropriate for a qualitative analysis following a grounded theory approach. After an analysis of the current state-of-the-art we will outline the methodological approach for our qualitative analysis that focuses on discovering tacit aspects of microblogging practices such as value or purpose. Finally the results of the online ethnographic approach and individual cases will be discussed and compared to similar studies. This work presents the explorative phase of a detailed qualitative approach towards exploring microblogging practices of scientists.

    The plutonium concentration data presented previously have consisted primarily of results from studies of short-term variations, i.e., the annual plutonium cycle conducted at Lake Michigan station ANL-5, 12 km SW of Grand Haven, Michigan. In this report, mean annual concentrations of total plutonium in unfiltered water from far off-shore (> 30 km) stations for the period 1971 through 1977, and from station ANL-5 (1975 through 1978) are summarized to establish the long-term trend in plutonium concentration in Lake Michigan. The results presented show that the mean annual concentration in the water column is similar at ANL-5 and at offshore stations and has decreased at the rate of only 6% per year during the period 1972 through 1978. The nearly constant concentration indicates that steady-state equilibria exist between plutonium inputs to the lake and the loss of plutonium from the water column. Observations suggest the existence of an active redox cycle for Pu in Lake Michigan. In this cycle, Pu IV atoms in solution are continually taken up by particulate materials but may be oxidized within microzones of the particles such as freshly deposited manganese coatings and also in solution by agents such as dissolved oxygen. In turn, the concentration of Pu VI in solution may be limited by reaction with reducing constituents of the coloidal-sized fraction (or decomposer organisms such as bacteria or fungi, which might have been present after filtration) and with planktonic organisms in the environment to produce Pu IV and thus maintain the cycle

    , and got, the opportunity to meet some high level Soviet administrators such as vice President Velikhov of the Academy of Sciences as well as Laboratory directors, and pressed the cases of individual scientists by name. This led to a memorable double existence. During the days I was an ``official guest" of the USSR, while in the evening I would visit colleagues who were fired ; on weekends I participated in Refusenick ``Sunday" Seminars in an apartment in Moscow. This all changed in 1991 with the end of communism in the USSR. Unfortunatly various authorities in the new Russia still violate the UN protocals and scientists there need support even now. The need to continue both individual & group mode of support continues to the present, and now includes helping colleagues in China, Cuba, Iran, the USA [Wen Ho Lee case],and other locales around the world. Intervention for Liu Gang [imprisoned in Beijing], Professor Fang LiZhi, and others in China, the brothers Drs Allaei in Iran, was and is still necessary. In all these cases we must have reliable information. We publicize by direct contact with officials of the relevant country. And very important is that we press the U S government to intervene. Even the step of having a US official inquire about a repressed scientist makes a difference. Judge Brandeis of the U S Supreme Court is the attributed author of the saying that ``Sunlight is the best disinfectant". Sunlight on repression can help end it. When Andrei Sakharov first visited New York at the Academy of Sciences in 1988 he gave us advice which I paraphrase ``Keep alert and informed of violations of Human Rights everywhere and protest both individually and together". Scientific work has deep rewards when you discover a new aspect or explanation for natural phenomena. Supporting repressed colleagues as part of the fabric of scientific work adds another dimension. Namely our satisfaction upon greeting Sakharov, Fang, and others and we know that to some degree our

    Public speaking organizations are highly valuable for individuals seeking to improve their skills in speech development and delivery. The methodology of such groups usually focuses on repetitive, guided practice. Toastmasters International, for instance, uses a curriculum based on topical manuals that guide their members through some number of prepared speeches with specific goals for each speech. I have similarly developed a public speaking manual for scientists with the intention of guiding scientists through the development and presentation of speeches that will help them hone their abilities as public speakers. I call this guide The Oratorical Scientist. The Oratorical Scientist will be a free, digital publication that is meant to guide scientists through five specific types of speech that the scientist may be called upon to deliver during their career. These five speeches are: The Coffee Talk, The Educational Talk, Research Talks for General Science Audiences, Research Talks for Specific Subdiscipline Audiences, and Taking the Big Stage (talks for public engagement). Each section of the manual focuses on speech development, rehearsal, and presentation for each of these specific types of speech. The curriculum was developed primarily from my personal experiences in public engagement. Individuals who use the manual may deliver their prepared speeches to groups of their peers (e.g. within their research group) or through video sharing websites like Youtube and Vimeo. Speeches that are broadcast online can then be followed and shared through social media networks (e.g. #OratoricalScientist), allowing a larger audience to evaluate the speech and to provide criticism. I will present The Oratorical Scientist, a guide for scientists to become better public speakers. The process of guided repetitive practice of scientific talks will improve the speaking capabilities of scientists, in turn benefitting science communication and public engagement.

    2001-07-01

    This paper discussed the construction and design of 3 affordable passive solar homes located in high latitudes: (1) the Kindred house located in a wooded subdivision in Hancock, Michigan; (2) the Autio house located in Laurium, Michigan; and the Mikkola house located in South Range, Michigan. The award-winning houses were part of the United States federal government's Energy Star program. The houses were constructed with common building materials in order to introduce the general public to the principles of energy-conscious passive solar design strategies and sustainable construction technologies. Super-insulation was used to retain solar heat gain in the houses. Air infiltration was minimized through the use of an airtight drywall sealing technique. Large windows were a prominent feature of the southern facades of the houses. The windows used fixed and casement low-e argon-filled insulated glazing. Average bills for the Kindred home are US$960 per year. It was concluded that passive solar design and construction strategies are now being used more often in the area as a result of the positive media coverage that the homes has received. 5 refs.

    My name is Cornelia Melcu and I am a primary school teacher in Brasov. Additionally, I am a teacher trainer of Preparatory Class Curriculum, Google Application in Education Course and European Projects Course and a mentor to new teachers and students in university. I am an eTwinning, Scientix and ESERO ambassador too. During the last three school years my school was involved in several STEM projects, part of Scientix community. The main goal of those projects was to develop basic STEM skills of our students based on project work integrated into the curriculum. Open the Gates to the Universe (http://gatestotheuniverse.blogspot.ro; https://twinspace.etwinning.net/12520/home) is an eTwinning project for primary school students started on September 2015 and finished on September 2016. Some of our partners were from the Mediterranean area. The students discovered different aspects of space science and astronomy working on international groups. They explored some aspects of Science included in their curriculum using resources from ESERO, ROEDUSEIS and Space Awareness (e.g. Calculate with Rosetta, Writing the travel diary, Build Rosetta, How to become an astronaut, etc.) The project was a great opportunity to apply integrated learning methods for developing competencies which are a part of the primary school curriculum in Romania. In Language and Communication classes the students talked about their partners living places and their traditions and habits. They learnt some basic words in their partners language related to the weather. They created stories- both in Romanian and English; they described life in space and astronomical phenomena. They talked to the other partners during the several online meetings we organized and wrote short stories in English. In Mathematics and Science they found out about the Milky Way, the Solar System, the weather, famous astronauts and astronomers. They calculated, solved problems, made experiments and explained specific natural phenomena

  16. Astronomers Discover Six-Image Gravitational Lens

    Science.gov (United States)

    2001-08-01

    An international team of astronomers has used the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope and NASA's Hubble Space Telescope (HST) to discover the first gravitational lens in which the single image of a very distant galaxy has been split into six different images. The unique configuration is produced by the gravitational effect of three galaxies along the line of sight between the more-distant galaxy and Earth. Optical and Radio Images of Gravitational Lens "This is the first gravitational lens with more than four images of the background object that is produced by a small group of galaxies rather than a large cluster of galaxies," said David Rusin, who just received his Ph.D. from the University of Pennsylvania. "Such systems are expected to be extremely rare, so this discovery is an important stepping stone. Because this is an intermediate case between gravitational lenses produced by single galaxies and lenses produced by large clusters of galaxies, it will give us insights we can't get from other types of lenses," Rusin added. The gravitational lens, called CLASS B1359+154, consists of a galaxy more than 11 billion light-years away in the constellation Bootes, with a trio of galaxies more than 7 billion light-years away along the same line of sight. The more-distant galaxy shows signs that it contains a massive black hole at its core and also has regions in which new stars are forming. The gravitational effect of the intervening galaxies has caused the light and radio waves from the single, more-distant galaxy to be "bent" to form six images as seen from Earth. Four of these images appear outside the triangle formed by the three intermediate galaxies and two appear inside that triangle. "This lens system is a very interesting case to study because it is more complicated than lenses produced by single galaxies, and yet simpler than lenses produced by clusters of numerous galaxies," said Chris Kochanek of the Harvard

  20. A scientist's guide to engaging decision makers

    Vano, J. A.

    2015-12-01

    Being trained as a scientist provides many valuable tools needed to address society's most pressing environmental issues. It does not, however, provide training on one of the most critical for translating science into action: the ability to engage decision makers. Engagement means different things to different people and what is appropriate for one project might not be for another. However, recent reports have emphasized that for research to be most useful to decision making, engagement should happen at the beginning and throughout the research process. There are an increasing number of boundary organizations (e.g., NOAA's Regional Integrated Sciences and Assessment program, U.S. Department of the Interior's Climate Science Centers) where engagement is encouraged and rewarded, and scientists are learning, often through trial and error, how to effectively include decision makers (a.k.a. stakeholders, practitioners, resource managers) in their research process. This presentation highlights best practices and practices to avoid when scientists engage decision makers, a list compiled through the personal experiences of both scientists and decision makers and a literature review, and how this collective knowledge could be shared, such as through a recent session and role-playing exercise given at the Northwest Climate Science Center's Climate Boot Camp. These ideas are presented in an effort to facilitate conversations about how the science community (e.g., AGU researchers) can become better prepared for effective collaborations with decision makers that will ultimately result in more actionable science.

  1. Scientists' internal models of the greenhouse effect

    Science.gov (United States)

    Libarkin, J. C.; Miller, H.; Thomas, S. R.

    2013-12-01

    A prior study utilized exploratory factor analysis to identify models underlying drawings of the greenhouse effect made by entering university freshmen. This analysis identified four archetype models of the greenhouse effect that appear within the college enrolling population. The current study collected drawings made by 144 geoscientists, from undergraduate geoscience majors through professionals. These participants scored highly on a standardized assessment of climate change understanding and expressed confidence in their understanding; many also indicated that they teach climate change in their courses. Although geoscientists held slightly more sophisticated greenhouse effect models than entering freshmen, very few held complete, explanatory models. As with freshmen, many scientists (44%) depict greenhouse gases in a layer in the atmosphere; 52% of participants depicted this or another layer as a physical barrier to escaping energy. In addition, 32% of participants indicated that incoming light from the Sun remains unchanged at Earth's surface, in alignment with a common model held by students. Finally, 3-20% of scientists depicted physical greenhouses, ozone, or holes in the atmosphere, all of which correspond to non-explanatory models commonly seen within students and represented in popular literature. For many scientists, incomplete models of the greenhouse effect are clearly enough to allow for reasoning about climate change. These data suggest that: 1) better representations about interdisciplinary concepts, such as the greenhouse effect, are needed for both scientist and public understanding; and 2) the scientific community needs to carefully consider how much understanding of a model is needed before necessary reasoning can occur.

    2012-07-01

    The purpose of this descriptive study was to explore Native American (NA) students' perceptions of scientists by using the Draw-A-Scientist Test and to determine if differences in these perceptions exist between grade level, gender, and level of cultural tradition. Data were collected for students in Grades 9-12 within a NA grant off-reservation boarding school. A total of 133 NA students were asked to draw a picture of a scientist at work and to provide a written explanation as to what the scientist was doing. A content analysis of the drawings indicated that the level of stereotype differed between all NA subgroups, but analysis of variance revealed that these differences were not significant between groups except for students who practised native cultural tradition at home compared to students who did not practise native cultural tradition at home (p educational and career science, technology, engineering, and mathematics paths in the future. The educational implication is that once initial perceptions are identified, researchers and teachers can provide meaningful experiences to combat the stereotypes.

  20. Scientists Involved in K-12 Education

    Science.gov (United States)

    Robigou, V.

    2004-12-01

    The publication of countless reports documenting the dismal state of science education in the 1980s, and the Third International Mathematics and Science Study (TIMMS) report (1996) called for a wider involvement of the scientific community in K-12 education and outreach. Improving science education will not happen without the collaboration of educators and scientists working in a coordinated manner and it requires a long-term, continuous effort. To contribute effectively to K-12 education all scientists should refer to the National Science Education Standards, a set of policies that guide the development of curriculum and assessment. Ocean scientists can also specifically refer to the COSEE recommendations (www.cosee.org) that led to the creation of seven regional Centers for Ocean Sciences Education Excellence. Scientists can get involved in K-12 education in a multitude of ways. They should select projects that will accommodate time away from their research and teaching obligations, their talent, and their interest but also contribute to the education reform. A few examples of effective involvement are: 1) collaborating with colleagues in a school of education that can lead to better education of all students and future teachers, 2) acting as a resource for a national program or a local science fair, 3) serving on the advisory board of a program that develops educational material, 4) speaking out at professional meetings about the value of scientists' involvement in education, 5) speaking enthusiastically about the teaching profession. Improving science education in addition to research can seem a large, overwhelming task for scientists. As a result, focusing on projects that will fit the scientist's needs as well as benefit the science reform is of prime importance. It takes an enormous amount of work and financial and personnel resources to start a new program with measurable impact on students. So, finding the right opportunity is a priority, and stepping

    2011-12-01

    The view from space has deepened our understanding of Earth as a global, dynamic system. Instruments on satellites and spacecraft, coupled with advances in ground-based research, have provided us with astonishing new perspectives of our planet. Now more than ever, enhancing the public's understanding of Earth's physical and biological systems is vital to helping citizens make informed policy decisions especially when they are faced with the consequences of global climate change. While the focus for education reform is on school improvement, there is considerable research that supports the role that out-of-school experiences can play in student achievement. Libraries provide an untapped resource for engaging underserved youth and their families in fostering an appreciation and deeper understanding of science and technology topics. The Space Science Institute's National Center for Interactive Learning (NCIL) in partnership with the American Library Association (ALA), the Lunar and Planetary Institute (LPI), and the National Girls Collaborative Project (NGCP) have received funding from NSF to develop a national project called the STAR Library Education Network: a hands-on learning program for libraries and their communities (or STAR-Net for short). STAR stands for Science-Technology, Activities and Resources. STAR-Net includes two exhibitions: Discover Earth and Discover Tech. The Discover Earth exhibition will focus on local earth science topics-such as weather, water cycle, and ecosystem changes-as well as a global view of our changing planet. The main take-away message (or Big Idea) for this exhibition is that the global environment changes - and is changed by - the host community's local environment. The project team is testing whether this approach will be a good strategy for engaging the public, especially in rural America. This presentation will provide an overview of the Discover Earth project and how it is integrating climate change ideas into the exhibit

  3. Scientists' Perceptions of Communicating During Crises

    2015-12-01

    To further our understanding of how to enhance student science and risk communication skills in natural hazards and earth science courses, we conducted a pilot study to assess the different perceptions of expert scientists and risk communication practitioners versus the perceptions of students. These differences will be used to identify expert views on best practice, and improve the teaching of communication skills at the University level. In this pilot study, a perceptions questionnaire was developed and validated. Within this, respondents (geoscientists, engineers, and emergency managers; n=44) were asked to determine their agreement with the use and effectiveness of specific communication strategies (within the first 72 hours after a devastating earthquake) when communicating to the public. In terms of strategies and information to the public, the respondents were mostly in agreement, but there were several statements which elicited large differences between expert responses: 1) the role and purpose of the scientific communication during crises (to persuade people to care, to provide advice, to empower people to take action); 2) the scientist's delivery (showing the scientists emotions and enthusiasm for scientific concepts they are discussing); and 3) the amount of data that is discussed (being comprehensive versus 'only the important' data). The most disagreed upon dimension was related to whether to disclose any political influence on the communication. Additionally, scientists identified that being an effective communicator was an important part of their job, and agreed that it is important to practice these skills. Respondents generally indicated that while scientists should be accountable for the science advice provided, they should not be held liable.

    The great importance of the fresh ground-water resources of Michigan is evident because 90 percent of the rural and about 70 percent of the total population of the State exclusive of the Detroit metropolitan area are supplied from underground sources. The water-supply and public-health problems that have been caused by some cases of ground-water contamination in the State illustrate the necessity of protecting this vital resource.Manmade and natural contaminants, including many types of chemical and organic matter, have entered many of the numerous aquifers of the State. Aquifers have been contaminated by waste-laden liquids percolating from the surface or from the zone of aeration and by direct injection to the aquifer itself. Industrial and domestic wastes, septic tanks, leaking sewers, flood waters or other poor quality surface waters, mine waters, solids stored or spread at the surface, and even airborne wastes all have been sources of ground-water contamination in Michigan. In addition, naturally occurring saline waters have been induced into other aquifers by overpumping or unrestricted flow from artesian wells, possibly by dewatering operations, and by the deepening of surface stream channels. Vertical migration of saline waters through open holes from formations underlying various important aquifers also has spoiled some of the fresh ground waters in the State. In spite of the contamination that has occurred, however, the total amount of ground water that has been spoiled is only a small part of the total resource. Neither is the contamination so widespread as that of the surface streams of Michigan.Overall legal authority to control most types of ground-water contamination in the State has been assigned by the Michigan Legislature to the Water Resources Commission, although the Department of Conservation and the Health Department also exercise important water-pollution control functions.

    Full Text Available A study was conducted to address the wind energy potential over Lake Michigan to support a commercial wind farm.  Lake Michigan is an inland sea in the upper mid-western United States.  A laser wind sensor mounted on a floating platform was located at the mid-lake plateau in 2012 and about 10.5 kilometers from the eastern shoreline near Muskegon Michigan in 2013.  Range gate heights for the laser wind sensor were centered at 75, 90, 105, 125, 150, and 175 meters.  Wind speed and direction were measured once each second and aggregated into 10 minute averages.  The two sample t-test and the paired-t method were used to perform the analysis.  Average wind speed stopped increasing between 105 m and 150 m depending on location.  Thus, the collected data is inconsistent with the idea that average wind speed increases with height. This result implies that measuring wind speed at wind turbine hub height is essential as opposed to using the wind energy power law to project the wind speed from lower heights.  Average speed at the mid-lake plateau is no more that 10% greater than at the location near Muskegon.  Thus, it may be possible to harvest much of the available wind energy at a lower height and closer to the shoreline than previously thought.  At both locations, the predominate wind direction is from the south-southwest.  The ability of the laser wind sensor to measure wind speed appears to be affected by a lack of particulate matter at greater heights.   Keywords: wind assessment, Lake Michigan, LIDAR wind sensor, statistical analysis.

    2008-11-01

    Children are inspired to follow career paths when they can imagine themselves there. Seeing pictures of adult individuals who look like them working in a given career can provide this spark to children's imaginations. Most (though not all) of the current available posters of scientists are of Einstein, and Einstein-like scientists. This is not representative of the current face of science. To change this, Pacific Science Center will host a photography exhibit: photographs of real, current scientists from all races, genders, beliefs, and walks of life. Photos will be taken and short biographies written by Discovery Corps Interns (Pacific Science Center's youth development program) to increase the amount of direct contact between students and scientists, and to give the exhibit an emotional connection for local teachers and families. We plan to make the photographs from this exhibit available to teachers for use in their classrooms, in addition to being displayed at Pacific Science Center during the International Year of Astronomy. The objectives of this project are to fill a need for representative photographs of scientists in the world community and to meet two of the goals of the International Year of Astronomy: to provide a modern image of science and scientists, and to improve the gender-balanced representation of scientists at all levels and promote greater involvement by under-represented minorities in scientific and engineering careers.

    Full Text Available Nobelist TD Lee scientist cooperation network (TDLSCN and their innovation ability are studied. It is found that the TDLSCN not only has the common topological properties both of scale-free and small-world for a general scientist cooperation networks, but also appears the creation multiple-peak phenomenon for number of published paper with year evolution, which become Nobelist TD Lee’s significant mark distinguished from other scientists. This new phenomenon has not been revealed in the scientist cooperation networks before. To demonstrate and explain this new finding, we propose a theoretical model for a nature scientist and his/her team innovation ability. The theoretical results are consistent with the empirical studies very well. This research demonstrates that the model has a certain universality and can be extended to estimate innovation ability for any nature scientist and his/her team. It is a better method for evaluating scientist innovation ability and his/her team for the academic profession and is of application potential.

  11. Most Powerful Eruption in the Universe Discovered

    Science.gov (United States)

    2005-01-01

    emission within the cavities shows that jets from the black hole erupted to create the cavities. Gas is being pushed away from the black hole at supersonic speeds over a distance of about a million light years. The mass of the displaced gas equals about a trillion Suns, more than the mass of all the stars in the Milky Way. LA Radio & Chandra X-ray Composite of MS 0735.6+7421 VLA Radio & Chandra X-ray Composite of MS 0735.6+7421 The rapid growth of supermassive black holes is usually detected by observing very bright radiation from the centers of galaxies in the optical and X-ray wavebands, or luminous radio jets. In MS 0735 no bright central radiation is found and the radio jets are faint. Therefore, the true nature of MS 0735 is only revealed through X-ray observations of the hot cluster gas. "Until now we had no idea that this black hole was gorging itself", said co-author Michael Wise of the Massachusetts Institute of Technology. "The discovery of this eruption shows that X-ray telescopes are necessary to understand some of the most violent events in the Universe." The astronomers estimated how much energy was needed to create the cavities by calculating the density, temperature and pressure of the hot gas. By making a standard assumption, that 10% of the gravitational energy goes into launching the jets, they estimated how much material the black hole swallowed. Size Comparison of MS 0735.6+7421 & Perseus Cluster Size Comparison of MS 0735.6+7421 & Perseus Cluster Besides generating the cavities, some of the energy from this eruption should keep the hot gas around the black hole from cooling, and some of it may also generate large-scale magnetic fields in the galaxy cluster. Chandra observers have discovered other cavities in galaxy clusters, but this one is easily the largest and the most powerful. For example, the energy content here exceeds that of the Perseus cavities by 250 times, and dwarfs the cavities in M87 by a factor of 10,000. NASA's Marshall Space Flight

    Science outreach demystifies science, and outreach media gives scientists a voice to engage the public. Today scientists are expected to communicate effectively not only with peers but also with a braod public audience, yet training incentiives are sometimes scarce. Media creation training is even less emphasized. Editing video to modern standards takes practice; arrangling light and framing shots isn't intuitive. While great tutorials exist, learning videography, story boarding, editing and sharing techniques will always require a commitment of time and effort. Yet ideally sharing science should be low-hanging fruit. FrontierScientists, a science-sharing website funded by the NSF, seeks to let scientists display their breakthroughs and share their excitement for their work with the public by working closely yet non-exhaustively with a professional media team. A director and videographer join scientists to film first-person accounts in the field or lab. Pictures and footage with field site explanations give media creators raw material. Scientists communicate efficiently and retain editorial control over the project, but a small team of media creators craft the public aimed content. A series of engaging short videos with narrow focuses illuminate the science. Written articles support with explanations. Social media campaigns spread the word, link content, welcome comments and keep abreast of changing web requirements. All FrontierScientists featured projects are aggregated to one mobile-friendly site available online or via an App. There groupings of Arctic-focused science provide a wealth of topics and content to explore. Scientists describe why their science is important, what drew them to it, and why the average American should care. When scientists share their work it's wonderful; a team approach is a schedule-friendly way that lets them serve as science communicators without taking up a handful of extra careers.

    This paper addresses the question of whether the International Linear Collider has the capability of discovering new particles that have not already been discovered at the CERN Large Hadron Collider. We summarize the various paths to discovery offered by the ILC, and discuss them in the context of three different scenarios: 1. LHC does not discover any new particles, 2. LHC discovers some new low mass states and 3. LHC discovers new heavy particles. We will show that in each case, ILC plays a critical role in discovery of new phenomena and in pushing forward the frontiers of high-energy physics as well as our understanding of the universe in a manner which is highly complementary to that of LHC. For the busy reader, a two-page executive summary is provided at the beginning of the document.

    Full Text Available As scientists we are often unprepared and unwilling to communicate our passion for what we do to those outside our professional circles. Scientific literature can also be difficult or unattractive to those without a professional interest in research. Storytelling can be a successful approach to enable readers to engage with the challenges faced by scientists. In an effort to convey to the public what it means to be a field biologist, 18 Portuguese biologists came together to write a book titled “BIOgraphies: The lives of those who study life”, in the original Portuguese “BIOgrafias: Vidas de quem estuda a vida”. This book is a collection of 35 field stories that became career landmarks for those who lived them. We discuss the obstacles and opportunities of the publishing process and reflect on the lessons learned for future outreach efforts.

    The Department of Defense has a methodology for targeting nuclear weapons, and a jargon that is used to communicate between the analysts, planners, aircrews, and missile crews. The typical engineer or scientist in the Department of Energy may not have been exposed to the nuclear weapons targeting terms and methods. This report provides an introduction to the terms and methodologies used for nuclear targeting. Its purpose is to prepare engineers and scientists to participate in wargames, exercises, and discussions with the Department of Defense. Terms such as Circular Error Probable, probability of hit and damage, damage expectancy, and the physical vulnerability system are discussed. Methods for compounding damage from multiple weapons applied to one target are presented.

    This paper is a review of a number of mathematical concepts from differential geometry and exterior calculus that are finding increasing application in the numerical solution of partial differential equations. The objective of the paper is to introduce the scientist/ engineer to some of these ideas via a number of concrete examples in 2, 3, and 4 dimensions. The goal is not to explain these ideas with mathematical precision but to present concrete examples and enable a physical intuition of these concepts for those who are not mathematicians. The objective of this paper is to provide enough context so that scientist/engineers can interpret, implement, and understand other works which use these elegant mathematical concepts.

    CERN is a magnet for many young people wanting to discover for themselves what the Laboratory is about through a traineeship. During their traineeships, the students develop an interest in engineering, informatics and also in physics, a discipline where there has been a marked fall-off in university applications.  We would therefore encourage you to take part in hosting students.   In 2009, CERN granted 270 students unremunerated traineeships lasting a few days or more. However, many applications could not be satisfied owing to the lack of CERN volunteers to supervise the students. The hosting of students in an aspect of one of the Organization’s fundamental missions, namely education and training.

    This comprehensively revised - essentially rewritten - new edition of the 1990 edition (described as ""extremely useful"" by MATHEMATICAL REVIEWS and as ""understandable and comprehensive"" by Scitech) guides readers through the dense array of mathematical information in the International Tables Volume A. Thus, most scientists seeking to understand a crystal structure publication can do this from this book without necessarily having to consult the International Tables themselves. This remains the only book aimed at non-crystallographers devoted to teaching them about crystallogr

    Diagnostic radiology has experienced many scientific and technical advances in the past decade. New imaging methods have allowed diagnostic procedures that have in some cases produced marked advances in treatment of disease. The complexity of the science and technology requires increased knowledge of equipment and techniques on the part of users. This, together with the necessity of exploration of other new developments in science and technology, requires a closer relationship between radiologists on the one hand and basic scientists on the other.

    The isolation of third world scientists from the modes of production and from the culture of their countries seems to be related to the alienation of the urban culture of these countries from their respective rural backgrounds. It is suggested that this alienation may be overcome by directly interfacing modern science and technology to the corresponding elements in their rural culture through the process of education.

    Over the past six years, as an Assistant Professor and now as an Associate Professor, I have engaged in educational outreach activities with K-12 teachers and their students. In this presentation I will talk about the successes and failures that I have had as a scientist engaged in K-12 educational outreach, including teaching the Earth System Science Education Alliance (ESSEA) distance learning course, teaching inquiry-based science to pre-service teachers through the NASA Opportunities for Visionary Academics (NOVA) program, GLOBE, school visits, and research projects with teachers and students. I will reflect on the potential impact this has had on my career, negative and positive. I will present ways that I have been able to engage in educational outreach while remaining a productive scientist, publishing research papers, etc. Obtaining grant funding to support a team of educational experts to assist me perform outreach has been critical to my groups success. However, reporting for small educational grants from state agencies can often be overwhelming. The bottom line is that I find working with teachers and students rewarding and believe that it is a critical part of me being a scientist. Through the process of working with teachers I have learned pedagogy that has helped me be a better teacher in the university classroom.

    Until recently the public had little time for, or interest in, studying scientific developments. Details on topics such as medical research, energy developments and communications advances were left to scientific journals and specialist conferences. For the most part the public had faith in science and science was able to maintain that faith through developments which recognizably improved the lot of mankind. But faith is no longer sufficient; scientists must now interact with people if we are to fulfil our obligations in this new theatre of increased public awareness. Scientists and egineers like myself and my colleagues at Atomic Energy of Canada Ltd. are communicating with the public as one part of a broad programme of public information. This includes: operation of public information centres, visits to our laboratories, interaction with teachers, distribution of reports and hosting exhibits. Technical people have a lot to learn about communicating with the public, the media and the critics. It is an extremely difficult task, but as concerned scientists it is something we should and must do, openly and constructively

    2016-01-01

    We present results of our work to reimagine Teacher-Scientist partnerships to improve relationships and outcomes. We describe our work in implementing Teacher-Scientist partnerships that are expanded to include a communicator, and the learners themselves, as genuine members of the partnership. Often times in Teacher-Scientist partnerships, the scientist can often become more easily described as a special guest into the classroom, rather than a genuine partner in the learning experience. We design programs that take the expertise of the teacher and the scientist fully into account to develop practical and meaningful partnerships, that are further enhanced by using an expert in communications to develop rich experiences for and with the learners. The communications expert may be from a broad base of backgrounds depending on the needs and desires of the partners -- the communicators include, for example: public speaking gurus; journalists; web and graphic designers; and American Sign Language interpreters. Our partnership programs provide online support and professional development for all parties. Outcomes of the program are evaluated in terms of not only learning outcomes for the students, but also attitude, behavior, and relationship outcomes for the teachers, scientists, communicators and learners alike.

    2016-06-07

    In order to map scientists' views on media channels and explore their experiences interacting with journalists, the authors conducted a survey of about 1,000 Brazilian scientists. Results indicate that scientists have clear and high expectations about how journalists should act in reporting scientific information in the media, but such expectations, in their opinion, do not always seem to be met. Nonetheless, the results show that surveyed scientists rate their relation with the media positively: 67% say that having their research covered by media has a positive impact on their colleagues. One quarter of the respondents expressed that talking to the media can facilitate acquisition of more funds for research. Moreover, 38% of the total respondents believe that writing about an interesting topic for release on media channels can also facilitate research publication in a scientific journal. However, 15% of the respondents outright agree that research reported in the media beforehand can threaten acceptance for publication by a scientific journal. We hope that these results can foster some initiatives for improving awareness of the two cultures, scientists and journalists; increasing the access of journalists to Brazilian scientific endeavors; stimulating scientists to communicate with the public via social networks.

    The Year of the Solar System (YSS) celebration begins in the fall of 2010. As YSS provides a means in which NASA can inspire members of the public about exciting missions to other worlds in our solar system, it is important to remember these missions are about the science being conducted and new discoveries being made. As part of the Year of the Solar System, Astromaterials Research and Exploration Science (ARES) Education, at the NASA Johnson Space Center, will infuse the great YSS celebration within the Expedition Earth and Beyond Program. Expedition Earth and Beyond (EEAB) is an authentic research program for students in grades 5-14 and is a component of ARES Education. Students involved in EEAB have the opportunity to conduct and share their research about Earth and/or planetary comparisons. ARES Education will help celebrate this exciting Year of the Solar System by inviting scientists to share their science. Throughout YSS, each month will highlight a topic related to exploring our solar system. Additionally, special mission events will be highlighted to increase awareness of the exciting missions and exploration milestones. To bring this excitement to classrooms across the nation, the Expedition Earth and Beyond Program and ARES Education will host classroom connection events in which scientists will have an opportunity to share discoveries being made through scientific research that relate to the YSS topic of the month. These interactive presentations will immerse students in some of the realities of exploration and potentially inspire them to conduct their own investigations. Additionally, scientists will share their own story of how they were inspired to pursue a STEM-related career that got them involved in exploration. These career highlights will allow students to understand and relate to the different avenues that scientists have taken to get where they are today. To bring the sharing of science full circle, student groups who conduct research by

    NASA's CALIPSO satellite mission provides an array of opportunities for teachers, students, and the general public. In developing our latest plan for education and public outreach, CALIPSO focused on efforts that would support students as scientists. CALIPSO EPO activities are aimed at inspiring young scientists through multiple avenues of potential contact, including: educator professional development, student-scientist mentoring, curriculum resource development, and public outreach through collaborative mission efforts. In this session, we will explore how these avenues complement one another and take a closer look at the development of the educator professional development activities. As part of CALIPSO's EPO efforts, we have developed the GLOBE Atmosphere Investigations Programs (AIP). The program encourages students to engage in authentic science through research on the atmosphere. The National Research Council (NRC) has emphasized the importance of teaching scientific inquiry in the National Science Education Standards (1996, 2000) and scientific practice in the recent Framework for K-12 Science Education (2011). In order to encourage student-centered science inquiry, teacher training utilizing GLOBE Atmosphere Investigations and GLOBE's Student Research Process are provided to middle and high school teachers to assist them in incorporating real scientific investigations into their classroom. Through participation in the program, teachers become a part of GLOBE (Global Learning and Observations to Benefit the Environment) - an international community of teachers, students, and scientists studying environmental science in over 24,000 schools around the world. The program uses NASA's satellites and the collection of atmosphere data by students to provide an engaging science learning experience for the students, and teachers. The GLOBE Atmosphere Investigations program offers year-long support to both teachers and students through direct involvement with NASA

    What do scientists think? That is an important question when engaging in science communication, in which an attempt is made to communicate the scientific understanding to a lay audience. To address this question we undertook a large and detailed survey among scientists studying various aspects of climate change , dubbed "perhaps the most thorough survey of climate scientists ever" by well-known climate scientist and science communicator Gavin Schmidt. Among more than 1800 respondents we found widespread agreement that global warming is predominantly caused by human greenhouse gases. This consensus strengthens with increased expertise, as defined by the number of self-reported articles in the peer-reviewed literature. 90% of respondents with more than 10 climate-related peer-reviewed publications (about half of all respondents), agreed that anthropogenic greenhouse gases are the dominant cause of recent global warming, i.e. having contributed more than half of the observed warming. With this survey we specified what the consensus position entails with much greater specificity than previous studies. The relevance of this consensus for science communication will be discussed. Another important result from our survey is that the main attribution statement in IPCC's fourth assessment report (AR4) may lead to an underestimate of the greenhouse gas contribution to warming, because it implicitly includes the lesser known masking effect of cooling aerosols. This shows the importance of the exact wording in high-profile reports such as those from IPCC in how the statement is perceived, even by fellow scientists. The phrasing was improved in the most recent assessment report (AR5). Respondents who characterized the human influence on climate as insignificant, reported having the most frequent media coverage regarding their views on climate change. This shows that contrarian opinions are amplified in the media in relation to their prevalence in the scientific community. This

    Practices related to parenteral (injectable) antineoplastic drugs (PADs) in Michigan hospitals were surveyed. All hospitals in Michigan were surveyed to assess compliance with American Society of Hospital Pharmacists (ASHP) and Occupational Safety and Health Administration (OSHA) recommendations related to PADs. Other PAD-related practice issues not covered within those guidelines were also studied. Surveys were mailed to the pharmacy directors of the state's 192 acute-care hospitals. Included were questions concerning policies and procedures for ordering, storing, preparing, handling, labeling, transporting, administering, and disposing of PADs. Questions concerning staff education, spill cleanup, and personnel issues were also included. A total of 169 questionnaires were returned, yielding a response rate of 88%. Of those respondents, 132 indicated that they prepare PAD doses for inpatients. Adherence rates were high for several of the PAD-preparation recommendations, including handwashing (97%) and gloving (98.5%). Rates for gowning (71.2%), labeling of PAD doses as biohazards (chemical hazards) (73.5%), and use of Class II biological-safety cabinets (71.2%) were less favorable. Practice areas with relatively poor adherence rates included use of plastic-backed absorbent pads under PAD preparation areas (53.8%), storing PADs separately from other drugs (48.5%), informing prospective employees of potential risks of handling PADs (36.4%), availability of spill kits (36.4%), and attaching and priming i.v. tubing before adding PADs to i.v. containers (5.4%). Many pharmacy departments in Michigan hospitals can substantially improve their adherence to ASHP and OSHA recommendations related to PADs.

    The buildup of salmonid populations in Lake Michigan through annual stockings of hatchery-reared fish may become limited by the quantity of forage fish, mainly alewives Alosa pseudoharengus, available for food. As a part of a continuing examination of salmonid predator-prey relations in Lake Michigan, we traced changes in alewife biomass estimated from bottom-trawl surveys conducted in late October and early November 1967–1978. Weight of adult alewives trawled per 0.5 hectare of bottom (10-minute drag) at 16 depths along eight transects between 1973 and 1977 formed a skewed distribution: 72 of 464 drags caught no alewives; 89 drags caught less than 1 kg; and 2 drags caught more than 100 kg (maximum 159 kg). Analysis of variance in normalized catch per tow indicated highly significant differences between the main effects of years and depths, and highly significant differences in the interactions of years and transects, years and depths, and transects and depths. Five geographic and depth strata, formed by combining parts of transects wherein mean catch rate did not differ significantly, were the basis for calculating annual estimates of adult alewife biomass (with 90% confidence intervals). Estimated biomass of alewives (±90% confidence limits) in Lake Michigan proper (Green Bay and Grand Traverse Bay excluded) rose gradually from 46,000 (±9,000) t in 1967 to 114,000 (±17,000) t in 1973, declined to 45,000 (±8,000) t in 1977, and rose to 77,000 (±19,000) t in 1978.

    Results of investigations of whistler mode ECRH plasma startup in the Michigan Mirror Machine are presented. Electron-velocity-distribution and plasma-spatial-distribution time evolution are characterized by measurements from axially and radially moveable Langmuir probes, an endloss current detector, an electron cyclotron emission radiometer, a foil-filtered X-ray detector, and a diamagnetic loop at the mirror midplane. Measurements of the buildup of both electron density and perpendicular pressure (nkT/sub perpendicular/) are compared to predictions from various numerical models. Both modeling and data suggest the creation of a highly anisotropic electron velocity distribution function with a ''sloshing electron'' axial density profile

    1981-01-01

    Clean and polluted air masses, advected over Lake Michigan, were studied using instrumental aircraft during the summers of 1976 and 1978. The results show that regardless of the degree of pollution, the particle size distribution is bimodal. The concentrations of sulfate, nitrate and trace metals in a clean air mass are more than an order of magnitude lower than those in polluted air masses. Furthermore, these concentrations are comparable with those measured in remote areas of the world. In clean air the ratio of the total light scattering to Rayleigh scattering is very close to one, indicating very low concentrations of particulates in the optically active size classes

    1966-01-01

    This discussion of the history of the Trenton Albion-Scipio trend in Michigan includes the location and development history, geology and reservoir characteristics, drilling and completion methods, production and history of both the Albion and Scipio Fields, production operation, and workover procedure. Maps, illustrations, and graphs of the topics discussed are included. The largest drilling problem encountered was lost circulation causing several blowouts, 2 of which resulted in spectacular fires. Production problems include paraffin deposition, corrosion and brine disposal. Well workovers have been performed in an attempt to correct one or more of 3 problems--high gas- oil ratio, high water cut, and low capacity.

    Real-time neutron radiography (RTNR) is rapidly becoming a valuable tool for nondestructive testing and basic research with a wide variety of applications. The Phoenix Memorial Laboratory (PML) at the University of Michigan has developed an RTNR facility and has been using this facility to study several phenomena of interest to researchers in many areas. These phenomena include imaging of the internal fluid flow in gas turbine engine nozzles and coking and debris deposition in several gas turbine nozzles. This paper presents a summary of the technique and facilities involved in these applications

  1. Surveillance for work-related skull fractures in Michigan.

    Science.gov (United States)

    Kica, Joanna; Rosenman, Kenneth D

    2014-12-01

    The objective was to develop a multisource surveillance system for work-related skull fractures. Records on work-related skull fractures were obtained from Michigan's 134 hospitals, Michigan's Workers' Compensation Agency and death certificates. Cases from the three sources were matched to eliminate duplicates from more than one source. Workplaces where the most severe injuries occurred were referred to OSHA for an enforcement inspection. There were 318 work related skull fractures, not including facial fractures, between 2010 and 2012. In 2012, after the inclusion of facial fractures, 316 fractures were identified of which 218 (69%) were facial fractures. The Bureau of Labor Statistic's (BLS) 2012 estimate of skull fractures in Michigan, which includes facial fractures, was 170, which was 53.8% of those identified from our review of medical records. The inclusion of facial fractures in the surveillance system increased the percentage of women identified from 15.4% to 31.2%, decreased severity (hospitalization went from 48.7% to 10.6% and loss of consciousness went from 56.5% to 17.8%), decreased falls from 48.2% to 27.6%, and increased assaults from 5.0% to 20.2%, shifted the most common industry from construction (13.3%) to health care and social assistance (15.0%) and the highest incidence rate from males 65+ (6.8 per 100,000) to young men, 20-24 years (9.6 per 100,000). Workplace inspections resulted in 45 violations and $62,750 in penalties. The Michigan multisource surveillance system of workplace injuries had two major advantages over the existing national system: (a) workplace investigations were initiated hazards identified and safety changes implemented at the facilities where the injuries occurred; and (b) a more accurate count was derived, with 86% more work-related skull fractures identified than BLS's employer based estimate. A more comprehensive system to identify and target interventions for workplace injuries was implemented using hospital and

    2013-12-01

    Whether they're guiding an unmanned aerial vehicle into a volcanic plume to sample aerosols, or documenting core drilling at a frozen lake in Siberia formed 3.6 million years ago by a massive meteorite impact, Arctic scientists are using video to enhance and expand their science and science outreach. FrontierScientists (FS), a forum for showcasing scientific work, produces and promotes radically different video blogs featuring Arctic scientists. Three- to seven- minute multimedia vlogs help deconstruct researcher's efforts and disseminate stories, communicating scientific discoveries to our increasingly connected world. The videos cover a wide range of current field work being performed in the Arctic. All videos are freely available to view or download from the FrontierScientists.com website, accessible via any internet browser or via the FrontierScientists app. FS' filming process fosters a close collaboration between the scientist and the media maker. Film creation helps scientists reach out to the public, communicate the relevance of their scientific findings, and craft a discussion. Videos keep audience tuned in; combining field footage, pictures, audio, and graphics with a verbal explanation helps illustrate ideas, allowing one video to reach people with different learning strategies. The scientists' stories are highlighted through social media platforms online. Vlogs grant scientists a voice, letting them illustrate their own work while ensuring accuracy. Each scientific topic on FS has its own project page where easy-to-navigate videos are featured prominently. Video sets focus on different aspects of a researcher's work or follow one of their projects into the field. We help the scientist slip the answers to their five most-asked questions into the casual script in layman's terms in order to free the viewers' minds to focus on new concepts. Videos are accompanied by written blogs intended to systematically demystify related facts so the scientists can focus

    The four states that border Lake Michigan are cooperatively applying a state-of-the-art nested photochemical grid model to assess the effects of potential emission control strategies on reducing elevated tropospheric ozone concentrations in the region to levels below the national ambient air quality standard. In order to provide an extensive database to support the application of the photochemical model, a substantial data collection effort known as the Lake Michigan Ozone Study (LMOS) was completed during the summer of 1991. The Lake Michigan Ozone Control Program (LMOP) was established by the States of Illinois, Wisconsin, Michigan, and Indiana to carry out the application of the modeling system developed from the LMOS, in terms of developing the attainment demonstrations required from this area by the Clean Air Act Amendments of 1990.

  5. Impact of a Scientist-Teacher Collaborative Model on Students, Teachers, and Scientists

    2015-09-01

    Collaborations between the K-12 teachers and higher education or professional scientists have become a widespread approach to science education reform. Educational funding and efforts have been invested to establish these cross-institutional collaborations in many countries. Since 2006, Taiwan initiated the High Scope Program, a high school science curriculum reform to promote scientific innovation and inquiry through an integration of advanced science and technology in high school science curricula through partnership between high school teachers and higher education scientists and science educators. This study, as part of this governmental effort, a scientist-teacher collaborative model (STCM) was constructed by 8 scientists and 4 teachers to drive an 18-week high school science curriculum reform on environmental education in a public high school. Partnerships between scientists and teachers offer opportunities to strengthen the elements of effective science teaching identified by Shulman and ultimately affect students' learning. Mixed methods research was used for this study. Qualitative methods of interviews were used to understand the impact on the teachers' and scientists' science teaching. A quasi-experimental design was used to understand the impact on students' scientific competency and scientific interest. The findings in this study suggest that the use of the STCM had a medium effect on students' scientific competency and a large effect on students' scientific individual and situational interests. In the interviews, the teachers indicated how the STCM allowed them to improve their content knowledge and pedagogical content knowledge (PCK), and the scientists indicated an increased knowledge of learners, knowledge of curriculum, and PCK.

  9. Scientists Toast the Discovery of Vinyl Alcohol in Interstellar Space

    Science.gov (United States)

    2001-10-01

    Astronomers using the National Science Foundation's 12 Meter Telescope at Kitt Peak, AZ, have discovered the complex organic molecule vinyl alcohol in an interstellar cloud of dust and gas near the center of the Milky Way Galaxy. The discovery of this long-sought compound could reveal tantalizing clues to the mysterious origin of complex organic molecules in space. Vinyl Alcohol and its fellow isomers "The discovery of vinyl alcohol is significant," said Barry Turner, a scientist at the National Radio Astronomy Observatory (NRAO) in Charlottesville, Va., "because it gives us an important tool for understanding the formation of complex organic compounds in interstellar space. It may also help us better understand how life might arise elsewhere in the Cosmos." Vinyl alcohol is an important intermediary in many organic chemistry reactions on Earth, and the last of the three stable members of the C2H4O group of isomers (molecules with the same atoms, but in different arrangements) to be discovered in interstellar space. Turner and his colleague A. J. Apponi of the University of Arizona's Steward Observatory in Tucson detected the vinyl alcohol in Sagittarius B -- a massive molecular cloud located some 26,000 light-years from Earth near the center of our Galaxy. The astronomers were able to detect the specific radio signature of vinyl alcohol during the observational period of May and June of 2001. Their results have been accepted for publication in the Astrophysical Journal Letters. Of the approximately 125 molecules detected in interstellar space, scientists believe that most are formed by gas-phase chemistry, in which smaller molecules (and occasionally atoms) manage to "lock horns" when they collide in space. This process, though efficient at creating simple molecules, cannot explain how vinyl alcohol and other complex chemicals are formed in detectable amounts. For many years now, scientists have been searching for the right mechanism to explain how the building

    Magnetic loops are building blocks of the closed-field corona. While active region loops are readily seen in images taken at EUV and X-ray wavelengths, quiet-Sun (QS) loops are seldom identifiable and are therefore difficult to study on an individual basis. The first analysis of solar minimum (Carrington Rotation 2077) QS coronal loops utilizing a novel technique called the Michigan Loop Diagnostic Technique (MLDT) is presented. This technique combines Differential Emission Measure Tomography and a potential field source surface (PFSS) model, and consists of tracing PFSS field lines through the tomographic grid on which the local differential emission measure is determined. As a result, the electron temperature T{sub e} and density N{sub e} at each point along each individual field line can be obtained. Using data from STEREO/EUVI and SOHO/MDI, the MLDT identifies two types of QS loops in the corona: so-called up loops in which the temperature increases with height and so-called down loops in which the temperature decreases with height. Up loops are expected, however, down loops are a surprise, and furthermore, they are ubiquitous in the low-latitude corona. Up loops dominate the QS at higher latitudes. The MLDT allows independent determination of the empirical pressure and density scale heights, and the differences between the two remain to be explained. The down loops appear to be a newly discovered property of the solar minimum corona that may shed light on the physics of coronal heating. The results are shown to be robust to the calibration uncertainties of the EUVI instrument.

  11. Data sharing by scientists: Practices and perceptions

    Science.gov (United States)

    Tenopir, C.; Allard, S.; Douglass, K.; Aydinoglu, A.U.; Wu, L.; Read, E.; Manoff, M.; Frame, M.

    2011-01-01

    Background: Scientific research in the 21st century is more data intensive and collaborative than in the past. It is important to study the data practices of researchers - data accessibility, discovery, re-use, preservation and, particularly, data sharing. Data sharing is a valuable part of the scientific method allowing for verification of results and extending research from prior results. Methodology/Principal Findings: A total of 1329 scientists participated in this survey exploring current data sharing practices and perceptions of the barriers and enablers of data sharing. Scientists do not make their data electronically available to others for various reasons, including insufficient time and lack of funding. Most respondents are satisfied with their current processes for the initial and short-term parts of the data or research lifecycle (collecting their research data; searching for, describing or cataloging, analyzing, and short-term storage of their data) but are not satisfied with long-term data preservation. Many organizations do not provide support to their researchers for data management both in the short- and long-term. If certain conditions are met (such as formal citation and sharing reprints) respondents agree they are willing to share their data. There are also significant differences and approaches in data management practices based on primary funding agency, subject discipline, age, work focus, and world region. Conclusions/Significance: Barriers to effective data sharing and preservation are deeply rooted in the practices and culture of the research process as well as the researchers themselves. New mandates for data management plans from NSF and other federal agencies and world-wide attention to the need to share and preserve data could lead to changes. Large scale programs, such as the NSF-sponsored DataNET (including projects like DataONE) will both bring attention and resources to the issue and make it easier for scientists to apply sound

    Science and activism are not mutually exclusive. In today's political and cultural landscape, scientists must become advocates. But we cannot simply support the scientific enterprise while ignoring marginalized groups in science. We must promote diversity and confront the structural inequalities and discrimination that are prevalent in science today. How do we begin to confront this challenge? 500 Women Scientists is a grassroots organization that formed in the wake of the 2016 US election. We quickly grew to more than 20,000 supporters from across the globe and moved towards a broader mission to serve society by making science open, inclusive, and accessible. Ensuring women's inclusion and an explicit consideration of diversity improves science and spurs innovation. A focus on diversity means that the best minds and talent are in the room and that we implement the most effective solutions to solve the complex global challenges we face. We accomplish our mission by bringing together communities to foster real change that comes from small groups, not large crowds. Across the world, groups of 500 Women Scientists - pods - help create deep roots through strong, personal relationships and focus on issues that resonate in their communities. Pod members meet regularly to carry out our mission through 3 types of activities: 1. Empowering women to succeed in science through mentorship, networking, and support; 2. Advocating for science through participation in marches and efforts like the "#ourEPA" and "Summer of Op-Eds" campaigns; and 3. Local outreach at schools, local community events, and more. We are building a powerful voice in conversations at the intersection of science and our most pressing issues: environmental degradation, gender politics, structural inequalities and cultural diversity. We tell our own story so that we do not remain `hidden figures,' and so that future generations can inherit and advance the knowledge that we work so hard to produce.

  13. Scientist impact factor (SIF): a new metric for improving scientists' evaluation?

    Science.gov (United States)

    Lippi, Giuseppe; Mattiuzzi, Camilla

    2017-08-01

    The publication of scientific research is the mainstay for knowledge dissemination, but is also an essential criterion of scientists' evaluation for recruiting funds and career progression. Although the most widespread approach for evaluating scientists is currently based on the H-index, the total impact factor (IF) and the overall number of citations, these metrics are plagued by some well-known drawbacks. Therefore, with the aim to improve the process of scientists' evaluation, we developed a new and potentially useful indicator of recent scientific output. The new metric scientist impact factor (SIF) was calculated as all citations of articles published in the two years following the publication year of the articles, divided by the overall number of articles published in that year. The metrics was then tested by analyzing data of the 40 top scientists of the local University. No correlation was found between SIF and H-index (r=0.15; P=0.367) or 2 years H-index (r=-0.01; P=0.933), whereas the H-index and 2 years H-index values were found to be highly correlated (r=0.57; Particles published in one year and the total number of citations to these articles in the two following years (r=0.62; Pscientists, wherein the SIF reflects the scientific output over the past two years thus increasing their chances to apply to and obtain competitive funding.

  14. The Impact of Scientist-Educator Collaborations: an early-career scientist's perspective

    Science.gov (United States)

    Roop, H. A.

    2017-12-01

    A decade ago, a forward-thinking faculty member exposed a group of aspiring scientists to the impacts and career benefits of working directly with K-12 students and educators. Ten years later, as one of those young scientists, it is clear that the relationships born out of this early experience can transform a researcher's impact and trajectory in science. Connections with programs like the NSF-funded PolarTREC program, the teacher-led Scientists in the Classroom effort, and through well-coordinated teacher training opportunities there are clear ways in which these partnerships can a) transform student learning; b) serve as a powerful and meaningful way to connect students to authentic research and researchers; and c) help researchers become more effective communicators by expanding their ability to connect their work to society. The distillation of science to K-12 students, with the expert eye of educators, makes scientists better at their work with tangible benefits to skills that matter in academia - securing funding, writing and communicating clearly and having high-value broader impacts. This invited abstract is submitted as part of this session's panel discussion and will explore in detail, with concrete examples, the mutual benefits of educator-scientist partnerships and how sustained engagement can transform the reach, connection and application of research science.

    2012-01-01

    All students and researchers in environmental and biological sciences require statistical methods at some stage of their work. Many have a preconception that statistics are difficult and unpleasant and find that the textbooks available are difficult to understand. Practical Statistics for Environmental and Biological Scientists provides a concise, user-friendly, non-technical introduction to statistics. The book covers planning and designing an experiment, how to analyse and present data, and the limitations and assumptions of each statistical method. The text does not refer to a specific comp

  1. Scientists Interacting With University Science Educators

    2004-12-01

    Scientists with limited time to devote to educating the public about their work will get the greatest multiplier effect for their investment of time by successfully interacting with university science educators. These university professors are the smallest and least publicized group of professionals in the chain of people working to create science literate citizens. They connect to all aspects of formal and informal education, influencing everything from what and how youngsters and adults learn science to legislative rulings. They commonly teach methods of teaching science to undergraduates aspiring to teach in K-12 settings and experienced teachers. They serve as agents for change to improve science education inside schools and at the state level K-16, including what science content courses are acceptable for teacher licensure. University science educators are most often housed in a College of Education or Department of Education. Significant differences in culture exist in the world in which marine scientists function and that in which university science educators function, even when they are in the same university. Subsequently, communication and building relationships between the groups is often difficult. Barriers stem from not understanding each other's roles and responsibilities; and different reward systems, assumptions about teaching and learning, use of language, approaches to research, etc. This presentation will provide suggestions to mitigate the barriers and enable scientists to leverage the multiplier effect saving much time and energy while ensuring the authenticity of their message is maintained. Likelihood that a scientist's message will retain its authenticity stems from criteria for a university science education position. These professors have undergraduate degrees in a natural science (e.g., biology, chemistry, physics, geology), and usually a master's degree in one of the sciences, a combination of natural sciences, or a master's including

    2003-12-01

    Field courses in remote and extreme environments immerse students in new and unfamiliar cultural and environmental settings where the impact from learning is high and the conventional wisdom, mindsets, and life skills of students are challenged. Through the Office of Study Abroad at Michigan State University (MSU), a new field course for undergraduates entitled `Studies in Antarctic System Science' embraces these principles. The three week, 6 credit course will be convened for the first time during the 2003-04 austral summer and will feature field based activities and classroom sessions beginning in Ushuaia, Tierra Del Fuego, Argentina. The defining experience of the program will be a cruise of the Antarctic Peninsula on a tourist ship partnered to the International Association of Antarctic Tour Operators (IAATO). This cruise will include landings on a daily basis at various sites of interest and international research stations en route. In 2003-04, the course will comprise 20 students and three faculty members from MSU. The non-major course curriculum has been compiled from materials based on original research by program faculty, relevant literature, information obtained directly from the international research community, and the Antarctic tourist industry. Subject areas will span multiple disciplines including palaeohistory and ecology, oceanography, climatology, geology and glaciology, marine, terrestrial and aerobiology, early exploration, policy and management, and the potential impacts from climate change and humans. It is intended that the course be repeated on an annual basis and that the curriculum be expanded to include greater coverage of ongoing research activities, especially NSF funded research. We welcome contact and feedback from educators and scientists interested in this endeavor, especially those who would like to broaden the impact of their own education interests or research by offering materials that could enhance the curriculum of the course

    The University of Michigan has been commissioned to conduct one of the largest environmental epidemiology studies (700 residents) of dioxin exposure among the population of Michigan to describe the pattern of serum dioxin levels among adults and to understand the factors that explain variation in serum dioxin levels. The study is being undertaken (2004-2006) in response to concerns among the population of Midland and Saginaw Counties that dioxins from the Dow Chemical Company facilities in Midland have resulted in contamination of areas of the City of Midland and have contaminated the sediments in the Tittabawassee River flood plain. There is concern that body burdens of dioxins are elevated because of environmental contamination. The appropriate way to respond to these concerns is to measure the serum dioxin levels in a probability sample of the population in the region and to estimate each individual's past exposure to various factors that are believed to contribute to the body burden of dioxins. By measuring factors that reflect potential exposure to dioxins through air, water, soil, food intake, occupations, and various recreational activities, we can identify the factors that correlate with (and explain variation in) serum dioxin levels. The central goal of the study is to determine which factors explain variation in serum dioxin levels, and to quantify how much variation each factor explains. This paper provides information on the planning phase, study scope and objectives.

    At the request of the US Department of Energy (DOE), a team from Oak Ridge National Laboratory conducted a radiological survey at 4400 Piehl Road in Ottawa Lake, Michigan. The survey was performed in September, 1992. The purpose of the survey was to determine if materials containing uranium from work performed under government contract at the former Baker Brothers facility in Toledo, Ohio had been transported off-site to this neighboring area. The radiological survey included surface gamma scans indoors and outdoors, alpha and beta scans inside the house and attached garage, beta-gamma scans of the hard surfaces outside, and the collection of soil, water, and dust samples for radionuclide analyses. Results of the survey demonstrated that the majority of the measurements on the property were within DOE guidelines. However, the presence of isolated spots of uranium contamination were found in two areas where materials were allegedly transported to the property from the former Baker Brothers site. Uranium uptake by persons on the property by ingestion is fairly unlikely, but inhalation is a possibility. Based on these findings, it is recommended that the residential property at 4400 Piehl Road in Ottawa Lake, Michigan be considered for inclusion under FUSRAP

  6. Time-Varying Value of Energy Efficiency in Michigan

    2018-04-02

    Quantifying the time-varying value of energy efficiency is necessary to properly account for all of its benefits and costs and to identify and implement efficiency resources that contribute to a low-cost, reliable electric system. Historically, most quantification of the benefits of efficiency has focused largely on the economic value of annual energy reduction. Due to the lack of statistically representative metered end-use load shape data in Michigan (i.e., the hourly or seasonal timing of electricity savings), the ability to confidently characterize the time-varying value of energy efficiency savings in the state, especially for weather-sensitive measures such as central air conditioning, is limited. Still, electric utilities in Michigan can take advantage of opportunities to incorporate the time-varying value of efficiency into their planning. For example, end-use load research and hourly valuation of efficiency savings can be used for a variety of electricity planning functions, including load forecasting, demand-side management and evaluation, capacity planning, long-term resource planning, renewable energy integration, assessing potential grid modernization investments, establishing rates and pricing, and customer service (KEMA 2012). In addition, accurately calculating the time-varying value of efficiency may help energy efficiency program administrators prioritize existing offerings, set incentive or rebate levels that reflect the full value of efficiency, and design new programs.

    The University of Michigan Nuclear Medicine Research Program, from instrumentation design through radiopharmaceutical development to clinical evaluation, is heavily dependent on the availability and use of iodine-123. Research activities at the University of Michigan can be divided into four major areas: instrumentation, radiochemistry, radiopharmaceutical development, and clinical evaluation. In the first category a new single-photon ring tomograph (SPRINT) has been built and is undergoing performance testing. SPRINT has been designed specifically for brain imaging with 123 I-labeled agents. In the area of radiochemistry, a simple radioiodide exchange technique has been developed for the rapid synthesis of 123 I-labeled aromatic compounds. In the radiopharmaceutical arena, a new agent, 123 I-meta-iodobenzyl-guanidine (MIBG), has been developed - the result of an extensive structure-distribution-relationship study. This radiopharmaceutical, a storage analog of norepinephrine, images organs with rich sympathetic innervation such as the heart and spleen. In the Nuclear Medicine Clinic three 123 I-labeled radiopharmaceuticals are undergoing evaluation

    Full Text Available Cycles of boom and bust plague mining communities around the globe, and decades after the bust the skeletons of shrunken cities remain. This article evaluates strategies for how former mining communities cope and strive for sustainability in the decades well beyond the bust, using a case study of Calumet, Michigan. In 1910, Calumet was at the center of the mining industry in the Upper Peninsula of Michigan, but in the century since its peak, mining employment steadily declined until the last mine closed in 1968, and the population declined by over 80%. This paper explores challenges, opportunities, and progress toward sustainability associated with arts-related development in this context. Methods are mixed, including observation, interviews, document review, a survey, and secondary data analysis. We follow Flora and Flora’s Community Capitals Framework to analyze progress toward sustainability. Despite key challenges associated with the shrunken city context (degraded tax base, overbuilt and aging infrastructure, diminished human capital, and a rather limited set of volunteers and political actors, we find the shrunken city also offers advantages for arts development, including low rents, less risk of gentrification, access to space, and political incentive. In Calumet, we see evidence of a spiraling up pattern toward social sustainability resulting from arts development; however impacts on environmental and economic sustainability are limited.

  12. Attitudes and norms affecting scientists' data reuse.

    Directory of Open Access Journals (Sweden)

    Renata Gonçalves Curty

    Full Text Available The value of sharing scientific research data is widely appreciated, but factors that hinder or prompt the reuse of data remain poorly understood. Using the Theory of Reasoned Action, we test the relationship between the beliefs and attitudes of scientists towards data reuse, and their self-reported data reuse behaviour. To do so, we used existing responses to selected questions from a worldwide survey of scientists developed and administered by the DataONE Usability and Assessment Working Group (thus practicing data reuse ourselves. Results show that the perceived efficacy and efficiency of data reuse are strong predictors of reuse behaviour, and that the perceived importance of data reuse corresponds to greater reuse. Expressed lack of trust in existing data and perceived norms against data reuse were not found to be major impediments for reuse contrary to our expectations. We found that reported use of models and remotely-sensed data was associated with greater reuse. The results suggest that data reuse would be encouraged and normalized by demonstration of its value. We offer some theoretical and practical suggestions that could help to legitimize investment and policies in favor of data sharing.

    Environmental science encompasses a wide range of disciplines from water chemistry to microbiology, ecology and atmospheric sciences. Studies often require working across disciplines which differ in their ways of describing and storing data such that it is not possible to devise a monolithic one-size-fits-all data solution. Based on our experiences with Consortium of the Universities for the Advancement of Hydrologic Science Inc. (CUAHSI) Observations Data Model, Berkeley Water Center FLUXNET carbon-climate work and by examining standards like EPA's Water Quality Exchange (WQX), we have developed a flexible data model that allows extensions without need to altering the schema such that scientists can define custom metadata elements to describe their data including observations, analysis methods as well as sensors and geographical features. The data model supports various types of observations including fixed point and moving sensors, bottled samples, rasters from remote sensors and models, and categorical descriptions (e.g. taxonomy) by employing user-defined-types when necessary. It leverages ADO .NET Entity Framework to provide the semantic data models for differing disciplines, while maintaining a common schema below the entity layer. This abstraction layer simplifies data retrieval and manipulation by hiding the logic and complexity of the relational schema from users thus allows programmers and scientists to deal directly with objects such as observations, sensors, watersheds, river reaches, channel cross-sections, laboratory analysis methods and samples as opposed to table joins, columns and rows.

  14. Anaxagoras and the Scientist/Laity Interaction

    Science.gov (United States)

    Woolf, N. J.

    The phenomenon that caused Anaxagoras to develop his model that explained the phases and eclipses of the Moon was a meteorite fall. The model was a turning point for science in explaining more than one phenomenon with a single model. It precipitated the growth of Greek astronomy and the first heliocentric theory. Anaxagoras was also the first scientist to get into trouble for a conflict between science and religion. Contrary to an impression from the title of this conference, scientific literature paid little attention to the meteorite fall phenomenon. Both scientists and the public mainly pay attention to models, and often to the extraneous irrelevant attachments of models, those by which it is placed in memory. Models are artistic creations that are culture dependent. Phenomena are our only solid link to the world of reality. The main issue of this paper is the problems that the individual has with models. The paper discusses the effect of Anaxagoras on scientific thought. It concludes by exploring three areas where relationship of science to society as Anaxagoras set it up, has left unresolved problems.

    The Center for Lunar Science and Exploration (CLSE), a collaboration between the Lunar and Planetary Institute (LPI) and NASA’s Johnson Space Center (JSC), is one of seven member teams of the NASA Lunar Science Institute (NLSI). In addition to research and exploration activities, the CLSE team is deeply invested in education and outreach. In support of NASA’s and NLSI’s objective to train the next generation of scientists, CLSE’s High School Lunar Research Project is a conduit through which high school students can actively participate in lunar science and learn about pathways into scientific careers. The High School Lunar Research Project engages teams of high school students in authentic lunar research that envelopes them in the process of science and supports the science goals of the CLSE. Most high school students’ lack of scientific research experience leaves them without an understanding of science as a process. Because of this, each team is paired with a lunar scientist mentor responsible for guiding students through the process of conducting a scientific investigation. Before beginning their research, students undertake “Moon 101,” designed to familiarize them with lunar geology and exploration. Students read articles covering various lunar geology topics and analyze images from past and current lunar missions to become familiar with available lunar data sets. At the end of “Moon 101”, students present a characterization of the geology and chronology of features surrounding the Apollo 11 landing site. To begin their research, teams choose a research subject from a pool of topics compiled by the CLSE staff. After choosing a topic, student teams ask their own research questions, within the context of the larger question, and design their own research approach to direct their investigation. At the conclusion of their research, teams present their results and, after receiving feedback, create and present a conference style poster to a panel of

  18. Preparing Scientists to be Community Partners

    2012-12-01

    Many students, especially students from historically under-represented communities, leave science majors or avoid choosing them because scientific careers do not offer enough opportunity to contribute to their communities. Citizen science, or public participation in scientific research, may address these challenges. At its most collaborative, it means inviting communities to partner in every step of the scientific process from defining the research question to applying the results to community priorities. In addition to attracting and retaining students, this level of community engagement will help diversify science, ensure the use and usability of our science, help buttress public support of science, and encourage the application of scientific results to policy. It also offers opportunities to tackle scientific questions that can't be accomplished in other way and it is demonstrably effective at helping people learn scientific concepts and methods. In order to learn how to prepare scientists for this kind of intensive community collaboration, we examined several case studies, including a project on disease and public health in Africa and the professionally evaluated experience of two summer interns in Southern Louisiana. In these and other cases, we learned that scientific expertise in a discipline has to be accompanied by a reservoir of humility and respect for other ways of knowing, the ability to work collaboratively with a broad range of disciplines and people, patience and enough career stability to allow that patience, and a willingness to adapt research to a broader set of scientific and non-scientific priorities. To help students achieve this, we found that direct instruction in participatory methods, mentoring by community members and scientists with participatory experience, in-depth training on scientific ethics and communication, explicit articulation of the goal of working with communities, and ample opportunity for personal reflection were essential

    2013-12-01

    The History of Winter (HOW) is a NASA Goddard Space Flight Center-funded teacher enrichment program that was started by Dr. Peter Wasilewski (NASA), Dr. Robert Gabrys (NASA) and Dr. Tony Gow (Cold Regions Research and Engineering Laboratory, or CRREL) in 2001 and continues with support and involvement of scientists from both the NASA Cryospheric Sciences Laboratory and CREEL. The program brings educators mostly from middle and high schools but also from state parks, community colleges and other institutions from across the US to the Northwood School (a small, private boarding school) in Lake Placid, NY for one week to learn about several facets of winter, polar, and snow research, including the science and history of polar ice core research, lake ice formation and structure, snow pack science, winter ecology, and remote sensing including current and future NASA cryospheric missions. The program receives support from the Northwood School staff to facilitate the program. The goal of the program is to create 'teachers as scientists' which is achieved through several hands-on field experiences in which the teachers have the opportunity to work with polar researchers from NASA, CRREL and partner Universities to dig and sample snow pits, make ice thin sections from lake ice, make snow shelters, and observe under-ice lake ecology. The hands-on work allows the teachers to use the same tools and techniques used in polar research while simultaneously introducing science concepts and activities to support their classroom work. The ultimate goal of the program is to provide the classroom teachers with the opportunity to learn about current and timely cryospheric research as well as to engage in real fieldwork experiences. The enthusiasm generated during the week-long program is translated into classroom activities with guidance from scientists, teachers and educational professionals. The opportunity to engage with polar researchers, both young investigators and renowned

    2006-01-01

    We collected lake whitefish Coregonus clupeaformis off Alpena and Tawas City, Michigan, USA in Lake Huron and off Muskegon, Michigan USA in Lake Michigan during 2002–2004. We determined energy density and percent dry weight for lake whitefish from both lakes and lipid content for Lake Michigan fish. Energy density increased with increasing fish weight up to 800 g, and then remained relatively constant with further increases in fish weight. Energy density, adjusted for weight, was lower in Lake Huron than in Lake Michigan for both small (≤800 g) and large fish (>800 g). Energy density did not differ seasonally for small or large lake whitefish or between adult male and female fish. Energy density was strongly correlated with percent dry weight and percent lipid content. Based on data from commercially caught lake whitefish, body condition was lower in Lake Huron than Lake Michigan during 1981–2003, indicating that the dissimilarity in body condition between the lakes could be long standing. Energy density and lipid content in 2002–2004 in Lake Michigan were lower than data for comparable sized fish collected in 1969–1971. Differences in energy density between lakes were attributed to variation in diet and prey energy content as well as factors that affect feeding rates such as lake whitefish density and prey abundance.

  1. Evaluating Michigan's community hospital access: spatial methods for decision support

    Directory of Open Access Journals (Sweden)

    2006-09-01

    Full Text Available Abstract Background Community hospital placement is dictated by a diverse set of geographical factors and historical contingency. In the summer of 2004, a multi-organizational committee headed by the State of Michigan's Department of Community Health approached the authors of this paper with questions about how spatial analyses might be employed to develop a revised community hospital approval procedure. Three objectives were set. First, the committee needed visualizations of both the spatial pattern of Michigan's population and its 139 community hospitals. Second, the committee required a clear, defensible assessment methodology to quantify access to existing hospitals statewide, taking into account factors such as distance to nearest hospital and road network density to estimate travel time. Third, the committee wanted to contrast the spatial distribution of existing community hospitals with a theoretical configuration that best met statewide demand. This paper presents our efforts to first describe the distribution of Michigan's current community hospital pattern and its people, and second, develop two models, access-based and demand-based, to identify areas with inadequate access to existing hospitals. Results Using the product from the access-based model and contiguity and population criteria, two areas were identified as being "under-served." The lower area, located north/northeast of Detroit, contained the greater total land area and population of the two areas. The upper area was centered north of Grand Rapids. A demand-based model was applied to evaluate the existing facility arrangement by allocating daily bed demand in each ZIP code to the closest facility. We found 1,887 beds per day were demanded by ZIP centroids more than 16.1 kilometers from the nearest existing hospital. This represented 12.7% of the average statewide daily bed demand. If a 32.3 kilometer radius was employed, unmet demand dropped to 160 beds per day (1

    2017-01-01

    Laboratories are both monasteries and space stations, redolent of the great ideas of generations past and of technologies to propel the future. Yet standard lab design has changed only little over recent years. Here Mark Fishman describes how to build labs as homes for scientists, to accommodate not just their fancy tools, but also their personalities. This richly illustrated book explores the roles of labs through history, from the alchemists of the Middle Ages to the chemists of the 19th and 20th centuries, and to the geneticists and structural biologists of today, and then turns to the special features of the laboratories Fishman helped to design in Cambridge, Shanghai, and Basel. Anyone who works in, or plans to build a lab, will enjoy this book, which will encourage them to think about how this special environment drives or impedes their important work.

He discusses his scientific contributions, from experiments that played a major role in establishing the nature and properties of cosmic rays to those establishing the existence of a solar wind and others that laid the foundations of X-ray astronomy. Rossi provides close insight into his actual experiences as a scientist and the motivations that gave direction to his research, and he recounts the beginning of very significant stages in high energy physics and space research. He writes evocatively of the many places where he worked--of Florence, Arcetri, Padua, and Venice, of the mountains of Colorado and the deserts of New Mexico. His narrative also provides insight into the life of a Jewish family in fascist Italy. The text is accompanied by photographs taken throughout Rossi's career.

  7. Nicholson Medal Lecture: Scientists and Totalitarian Societies

    Fang, Li-Zhi

    1997-04-01

    In order to call for support for his policy in China from the scientific community outside of China, Li Peng, China's premier today and at the time of Tiananmen massacre in 1989, published an editorial of ``Science" magazine (July 5, 1996) titled ``Why China needs science ... and partners." This editorial brought a serious problem, which is originally faced by scientists in a totalitarian society, upon the scientific community in free societies outside. It is well known that the current attitude of the Chinese government toward science is what it was during the years of Mao and the Soviet Union: science is limited to provide instruments useful to the rulers, but any degree of freedom, such as to challenge ideas, required by science to change the totalitarian regime itself, is suppressed. Thus, the problem facing us is: how to help your colleagues and promote science in a totalitarian society, without becoming a partner of the injustices of that regime.

    Marshall Space Flight Center pursues scientific research in the area of low-gravity effects on materials and processes. To facilitate these Government performed research responsibilities, a number of supplementary research tasks were accomplished by a group of specialized visiting scientists. They participated in work on contemporary research problems with specific objectives related to current or future space flight experiments and defined and established independent programs of research which were based on scientific peer review and the relevance of the defined research to NASA microgravity for implementing a portion of the national program. The programs included research in the following areas: protein crystal growth, X-ray crystallography and computer analysis of protein crystal structure, optimization and analysis of protein crystal growth techniques, and design and testing of flight hardware.

    NASA Langley partnered with the Virginia Living Museum and two schools to create ozone bio-indicator gardens for citizen scientists of all ages. The garden at the Marshall Learning Center is part of a community vegetable garden designed to teach young children where food comes from and pollution in their area, since most of the children have asthma. The Mt. Carmel garden is located at a K-8 school. Different ozone sensitive and ozone tolerant species are growing and being monitored for leaf injury. In addition, CairClip ozone monitors were placed in the gardens and data are compared to ozone levels at the NASA Langley Chemistry and Physics Atmospheric Boundary Layer Experiment (CAPABLE) site in Hampton, VA. Leaf observations and plant measurements are made two to three times a week throughout the growing season.

    2017-07-31

    Quark Matter conference series are amongst the major scientific events for the Relativistic Heavy Ion community. With over 30 year long history, the meetings are held about every 1½ years to showcase the progress made in theoretical and experimental studies of nuclear matter under extreme conditions. The 26th International Conference on Ultra-relativistic Nucleus-Nucleus Collisions (Quark Matter 2017) was held at the Hyatt Regency Hotel in downtown Chicago from Sunday, February 5th through Saturday, February 11th, 2017. The conference featured about 180 plenary and parallel presentations of the most significant recent results in the field, a poster session for additional presentations, and an evening public lecture. Following the tradition of previous Quark Matter meetings, the first day of the conference was dedicated entirely to a special program for young scientists (graduate students and postdoctoral researchers). This grant will provided financial support for 235 young physicists facilitating their attendance of the conference.

    2015-05-01

    Building a successful professional career in the physician-scientist realm is rewarding but challenging, especially in the dynamic and competitive environment of today's modern society. This educational review aims to provide readers with five important career development lessons drawn from the business and social science literatures. Lessons 1-3 describe career strategy, with a focus on promoting one's strengths while minimizing fixing one's weaknesses (Lesson 1); effective time management in the pursuit of long-term goals (Lesson 2); and the intellectual flexibility to abandon/modify previously made decisions while embracing emerging opportunities (Lesson 3). Lesson 4 explains how to maximize the alternative benefits of English-language fluency (i.e., functions such as signaling and cognition-enhancing capabilities). Finally, Lesson 5 discusses how to enjoy happiness and stay motivated in a harsh, zero-sum game society.

  12. Linear functional analysis for scientists and engineers

    CERN Document Server

    Limaye, Balmohan V

    2016-01-01

    This book provides a concise and meticulous introduction to functional analysis. Since the topic draws heavily on the interplay between the algebraic structure of a linear space and the distance structure of a metric space, functional analysis is increasingly gaining the attention of not only mathematicians but also scientists and engineers. The purpose of the text is to present the basic aspects of functional analysis to this varied audience, keeping in mind the considerations of applicability. A novelty of this book is the inclusion of a result by Zabreiko, which states that every countably subadditive seminorm on a Banach space is continuous. Several major theorems in functional analysis are easy consequences of this result. The entire book can be used as a textbook for an introductory course in functional analysis without having to make any specific selection from the topics presented here. Basic notions in the setting of a metric space are defined in terms of sequences. These include total boundedness, c...

    Fisher, E R; Partin, K M

    2014-01-01

    Although it might seem to be a simple task for scientists to avoid plagiarism and thereby an allegation of research misconduct, assessment of trainees in the Responsible Conduct of Research and recent findings from the National Science Foundation Office of Inspector General regarding plagiarism suggests otherwise. Our experiences at a land-grant academic institution in assisting researchers in avoiding plagiarism are described. We provide evidence from a university-wide multi-disciplinary course that understanding how to avoid plagiarism in scientific writing is more difficult than it might appear, and that a failure to learn the rules of appropriate citation may cause dire consequences. We suggest that new strategies to provide training in avoiding plagiarism are required.

  14. Modern physics for scientists and engineers

    CERN Document Server

    Morrison, John C

    2015-01-01

    The second edition of Modern Physics for Scientists and Engineers is intended for a first course in modern physics. Beginning with a brief and focused account of the historical events leading to the formulation of modern quantum theory, later chapters delve into the underlying physics. Streamlined content, chapters on semiconductors, Dirac equation and quantum field theory, as well as a robust pedagogy and ancillary package, including an accompanying website with computer applets, assist students in learning the essential material. The applets provide a realistic description of the energy levels and wave functions of electrons in atoms and crystals. The Hartree-Fock and ABINIT applets are valuable tools for studying the properties of atoms and semiconductors.

  15. Climate Change: On Scientists and Advocacy

    Science.gov (United States)

    Schmidt, Gavin A.

    2014-01-01

    Last year, I asked a crowd of a few hundred geoscientists from around the world what positions related to climate science and policy they would be comfortable publicly advocating. I presented a list of recommendations that included increased research funding, greater resources for education, and specific emission reduction technologies. In almost every case, a majority of the audience felt comfortable arguing for them. The only clear exceptions were related to geo-engineering research and nuclear power. I had queried the researchers because the relationship between science and advocacy is marked by many assumptions and little clarity. This despite the fact that the basic question of how scientists can be responsible advocates on issues related to their expertise has been discussed for decades most notably in the case of climate change by the late Stephen Schneider.

    Business Planning for Scientists and Engineers is a combination text/workbook intended for use by individuals and firms having received Phase II SBIR funding (Small Business Innovation Research). It is used to best advantage in combination with other aspects of the Commercialization Assistance Project developed by Dawnbreaker for the US Department of Energy. Although there are many books on the market which indicate the desired contents of a business plan, there are none which clearly indicate how to find the needed information. This book focuses on the how of business planning: how to find the needed information; how to keep yourself honest about the market potential; how to develop the plan; how to sell and use the plan.

  17. Quantum Genetic Algorithms for Computer Scientists

    Directory of Open Access Journals (Sweden)

    Rafael Lahoz-Beltra

    2016-10-01

    Full Text Available Genetic algorithms (GAs are a class of evolutionary algorithms inspired by Darwinian natural selection. They are popular heuristic optimisation methods based on simulated genetic mechanisms, i.e., mutation, crossover, etc. and population dynamical processes such as reproduction, selection, etc. Over the last decade, the possibility to emulate a quantum computer (a computer using quantum-mechanical phenomena to perform operations on data has led to a new class of GAs known as “Quantum Genetic Algorithms” (QGAs. In this review, we present a discussion, future potential, pros and cons of this new class of GAs. The review will be oriented towards computer scientists interested in QGAs “avoiding” the possible difficulties of quantum-mechanical phenomena.

  18. A Word to the Wise: Advice for Scientists Engaged in Collaborative Adaptive Management

    Science.gov (United States)

    Hopkinson, Peter; Huber, Ann; Saah, David S.; Battles, John J.

    2017-05-01

    Collaborative adaptive management is a process for making decisions about the environment in the face of uncertainty and conflict. Scientists have a central role to play in these decisions. However, while scientists are well trained to reduce uncertainty by discovering new knowledge, most lack experience with the means to mitigate conflict in contested situations. To address this gap, we drew from our efforts coordinating a large collaborative adaptive management effort, the Sierra Nevada Adaptive Management Project, to offer advice to our fellow environmental scientists. Key challenges posed by collaborative adaptive management include the confusion caused by multiple institutional cultures, the need to provide information at management-relevant scales, frequent turnover in participants, fluctuations in enthusiasm among key constituencies, and diverse definitions of success among partners. Effective strategies included a dedication to consistency, a commitment to transparency, the willingness to communicate frequently via multiple forums, and the capacity for flexibility. Collaborative adaptive management represents a promising, new model for scientific engagement with the public. Learning the lessons of effective collaboration in environmental management is an essential task to achieve the shared goal of a sustainable future.

  19. Communicating Ecology Through Art: What Scientists Think

    Directory of Open Access Journals (Sweden)

    David J. Curtis

    2012-06-01

    Full Text Available Many environmental issues facing society demand considerable public investment to reverse. However, this investment will only arise if the general community is supportive, and community support is only likely if the issues are widely understood. Scientists often find it difficult to communicate with the general public. The role of the visual and performing arts is often overlooked in this regard, yet the arts have long communicated issues, influenced and educated people, and challenged dominant paradigms. To assess the response of professional ecologists to the role of the arts in communicating science, a series of constructed performances and exhibitions was integrated into the program of a national ecological conference over five days. At the conclusion of the conference, responses were sought from the assembled scientists and research students toward using the arts for expanding audiences to ecological science. Over half the delegates said that elements of the arts program provided a conducive atmosphere for receiving information, encouraged them to reflect on alternative ways to communicate science, and persuaded them that the arts have a role in helping people understand complex scientific concepts. A sizeable minority of delegates (24% said they would consider incorporating the arts in their extension or outreach efforts. Incorporating music, theatre, and dance into a scientific conference can have many effects on participants and audiences. The arts can synthesize and convey complex scientific information, promote new ways of looking at issues, touch people's emotions, and create a celebratory atmosphere, as was evident in this case study. In like manner, the visual and performing arts should be harnessed to help extend the increasingly unpalatable and urgent messages of global climate change science to a lay audience worldwide.

  20. An example of woman scientist in France

    Science.gov (United States)

    Cazenave, A.

    2002-12-01

    Although the presence of women in sciences has been increasing in the past few decades in Europe, it remains incredibly low at the top levels. Recent statistics from the European Commission indicate that now women represent 50 per cent of first degree students in many countries. However, the proportion of women at each stage of the scientific career decreases almost linearly, reaching less than 10 per cent at the highest level jobs. From my own experience, I don't think that this results from sexism nor discrimination. Rather, I think that this is a result of complex cultural factors making women subconsciously persuaded that top level jobs are destined to male scientists only. Many women scientists drop the idea of playing a role at high-level research, considering it is a way of exerting power (a matter reserved to men). Others give up the possibility of combining childcare and high level commitments in research. And too many (married women) still find only natural to sacrifice their own scientific ambitions to the benefit of their spouse's career. In this poster, I briefly present my personal experience. I chose to prioritize scientific productivity and expertise versus hierarchical responsibilities. Besides I tried to keep a satisfactory balance between family demand and research involvement. This was indeed facilitated by the French system, which provides substantial support to women's work (nurseries, recreation centers during school holidays, etc.). To my point of view, the most promising way of increasing the number of women at top levels in research is through education and mentality evolution

    2016-12-01

    Building a network of collaborators and colleagues is a key professional development activity for early career scientists (ECS) dealing with a challenging job market. At large conferences, young scientists often focus on interacting with senior researchers, competing for a small number of positions in leading laboratories. However, building a strong, international network amongst their peers in related disciplines is often as valuable in the long run. The Deep Carbon Observatory (DCO) began funding a series of workshops in 2014 designed to connect early career researchers within its extensive network of multidisciplinary scientists. The workshops, by design, are by and for early career scientists, thus removing any element of competition and focusing on peer-to-peer networking, collaboration, and creativity. The successful workshops, organized by committees of early career deep carbon scientists, have nucleated a lively community of like-minded individuals from around the world. Indeed, the organizers themselves often benefit greatly from the leadership experience of pulling together an international workshop on budget and on deadline. We have found that a combination of presentations from all participants in classroom sessions, professional development training such as communication and data management, and field-based relationship building and networking is a recipe for success. Small groups within the DCO ECS network have formed; publishing papers together, forging new research directions, and planning novel and ambitious field campaigns. Many DCO ECS also have come together to convene sessions at major international conferences, including the AGU Fall Meeting. Most of all, there is a broad sense of camaraderie and accessibility within the DCO ECS Community, providing the foundation for a career in the new, international, and interdisciplinary field of deep carbon science.

  2. History and Outcomes of 50 Years of Physician-Scientist Training in Medical Scientist Training Programs.

    2017-10-01

    Physician-scientists are needed to continue the great pace of recent biomedical research and translate scientific findings to clinical applications. MD-PhD programs represent one approach to train physician-scientists. MD-PhD training started in the 1950s and expanded greatly with the Medical Scientist Training Program (MSTP), launched in 1964 by the National Institute of General Medical Sciences (NIGMS) at the National Institutes of Health. MD-PhD training has been influenced by substantial changes in medical education, science, and clinical fields since its inception. In 2014, NIGMS held a 50th Anniversary MSTP Symposium highlighting the program and assessing its outcomes. In 2016, there were over 90 active MD-PhD programs in the United States, of which 45 were MSTP supported, with a total of 988 trainee slots. Over 10,000 students have received MSTP support since 1964. The authors present data for the demographic characteristics and outcomes for 9,683 MSTP trainees from 1975-2014. The integration of MD and PhD training has allowed trainees to develop a rigorous foundation in research in concert with clinical training. MSTP graduates have had relative success in obtaining research grants and have become prominent leaders in many biomedical research fields. Many challenges remain, however, including the need to maintain rigorous scientific components in evolving medical curricula, to enhance research-oriented residency and fellowship opportunities in a widening scope of fields targeted by MSTP graduates, to achieve greater racial diversity and gender balance in the physician-scientist workforce, and to sustain subsequent research activities of physician-scientists.

    This review examines the validity of the Michigan Alcoholism Screening Test (MAST) as a screening instrument for alcohol problems. Studies that compare the MAST-questionnaire with other defined diagnostic criteria of alcohol problems were retrieved through MEDLINE and a cross-bibliographic check....... A total of 20 validity studies were included. The studies varied considerably regarding the prevalence of alcohol problems, the diagnostic criteria, and the examined patient categories. The MAST compared with other diagnostic criteria of alcohol problems gave validity measures with the following span...... and the specificities show substantial variations. The variables that seem to have the largest influence on the PVpos seem to be the prevalence of alcohol problems, the diagnostic method against which the MAST-questionnaire is validated, and the populations on which the MAST is applied. The MAST should in the future...

  6. Arsenic species and chemistry in groundwater of southeast Michigan

    Kim, M.-J.; Nriagu, Jerome; Haack, Sheridan

    2002-01-01

    Most of the arsenic detected was arsenite [As(III)]. - Groundwater samples, taken from 73 wells in 10 counties of southeast Michigan in 1997 had arsenic concentrations in the range of 0.5 to 278 μg/l, the average being 29 μg/l. About 12% of these wells had arsenic concentrations that exceeded the current USEPA's maximum contaminant level of 50 μg/l. Most (53-98%) of the arsenic detected was arsenite [As(III)] and other observations supported the arsenic species distribution (low redox potential and DO). In shallow groundwater ( 15 m), the concentration of arsenic is possibly controlled by reductive dissolution of arsenic-rich iron hydroxide/oxyhydroxide and dissolution of arsenic sulfide minerals

    Breslin, Tara M; Waldinger, Marcy; Silver, Samuel M

    2014-02-01

    The University of Michigan Comprehensive Cancer Center (UMCCC) Opportunities for Improvement project involved a detailed patient-level medical record review, feedback to medical providers and clinical leadership, and discussion of potential predictors of discordant or delayed care. The medical record review revealed that reasons for discordant or delayed care were well documented by clinical providers, and medical comorbidity was the most common predisposing factor. Another common theme was the difficulty in obtaining treatment records for patients who received a portion of their care outside UMCCC. The project provided a valuable opportunity to examine established processes of care and data collection and consider how the newly implemented electronic health record might support future efforts aimed at improving efficiency and communication among providers.

    2016-01-01

    Interactions between humans and carnivores have existed for centuries due to competition for food and space. American black bears are increasing in abundance and populations are expanding geographically in many portions of its range, including areas that are also increasing in human density, often resulting in associated increases in human-bear conflict (hereafter, bear incidents). We used public reports of bear incidents in Michigan, USA, from 2003-2011 to assess the relative contributions of ecological and anthropogenic variables in explaining the spatial distribution of bear incidents and estimated the potential risk of bear incidents. We used weighted Normalized Difference Vegetation Index mean as an index of primary productivity, region (i.e., Upper Peninsula or Lower Peninsula), primary and secondary road densities, and percentage land cover type within 6.5-km2 circular buffers around bear incidents and random points. We developed 22 a priori models and used generalized linear models and Akaike's Information Criterion (AIC) to rank models. The global model was the best compromise between model complexity and model fit (w = 0.99), with a ΔAIC 8.99 units from the second best performing model. We found that as deciduous forest cover increased, the probability of bear incident occurrence increased. Among the measured anthropogenic variables, cultivated crops and primary roads were the most important in our AIC-best model and were both positively related to the probability of bear incident occurrence. The spatial distribution of relative bear incident risk varied markedly throughout Michigan. Forest cover fragmented with agriculture and other anthropogenic activities presents an environment that likely facilitates bear incidents. Our map can help wildlife managers identify areas of bear incident occurrence, which in turn can be used to help develop strategies aimed at reducing incidents. Researchers and wildlife managers can use similar mapping techniques to

  11. Project U-Turn: increasing active transportation in Jackson, Michigan.

    Science.gov (United States)

    TenBrink, David S; McMunn, Randall; Panken, Sarah

    2009-12-01

    Jackson, Michigan, is a medium-sized city suffering from a bad economy and obesity-related health issues. Nearly 20% of the 36,000 residents live below the poverty line. It is a relatively young city (median age of 30 years) with a mixed ethnicity (20% black, 73% white, 4% Hispanic). The city offers many structured, active recreational opportunities, but has not integrated physical activity into daily life. Project U-Turn aimed to increase active transportation (e.g., biking, walking, and transit use) through an integrated approach to Active Living by Design's community action model and the Michigan Safe Routes to School model. Resources were focused on active living promotions and programs; partnership meetings were the source of changes in policy and physical projects. Each initiative was designed to introduce each of the 5Ps (preparation, promotion, programs, policy, and physical projects) to build support for the partnership's overall work. The partnership collected snapshot data of community walking and biking behavior, percentage of students walking to school, participation in events and programs, and new physical projects. Jackson saw a vast improvement in physical infrastructure and policy and a related increase in walking and biking in the community. The project engaged in purposeful partnership building to implement effective programs and promotions that built support for policy and physical projects. Limited resources were best used by encouraging partners to contribute and coordinate activities using existing staff, funding, and resources. Jackson has seen a shift toward awareness of the benefits of active living on community health, economic development, and environmental awareness.

    Schinske, Jeffrey N.; Perkins, Heather; Snyder, Amanda; Wyer, Mary

    2016-01-01

    Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments (“Scientist Spotlights”) that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms.

  14. Supervising Scientist, Annual Report 2000-2001

    International Nuclear Information System (INIS)

    2001-01-01

    The year under review has seen the resolution of the major issue that has dominated the work of the Supervising Scientist Division over the past three years the review of scientific uncertainties associated with the environmental assessment of the proposal to mine uranium at Jabiluka. The Supervising Scientist prepared a comprehensive report on the risks associated with mining at Jabiluka, which has been under various stages of peer review by an Independent Science Panel (ISP) appointed by the WHC since May 1999. This process culminated in a visit to Australia by the ISP in July 2000 for detailed discussion and assessment and the submission of the final report of the ISP to the World Heritage Committee in September 2000. The report of the ISP was considered at the meeting of the World Heritage Committee in Cairns in December 2000. The Committee reached the conclusion that 'the currently approved proposal for the mine and mill at Jabiluka does not threaten the health of people or the biological and ecological systems of Kakadu National Park that the Mission believed to be at risk'. As a result, the WHC decided not to register Kakadu National Park on the World Heritage List in Danger. But the people of Kakadu themselves remain to be convinced. A major challenge is to gain the confidence of Aboriginal people in the integrity and independence of our scientific assessments and to reduce the concerns that they have for the future of their people and their country. Monitoring of the Jabiluka project was extensive throughout the reporting period. Chemical and biological monitoring programmes of Energy Resources of Australia (ERA) and the Environmental Research Institute of the Supervising Scientist (ERISS) demonstrated that no adverse impact occurred in downstream aquatic ecosystems. Similarly, radiological measurements close to the nearest population centre demonstrated that radiation exposure of the public due to current operations at Jabiluka is not detectable

    Each year, drought impacts various regions of the United States on time scales of weeks, months, seasons, or years, which in turn leads to a need to document these impacts and inform key decisions on land management, use of water resources, and disaster response. Mapping impacts allows decision-makers to understand potential damage to agriculture and loss of production, to communicate and document drought impacts on crop yields, and to inform water management decisions. Current efforts to collect this information includes parsing of media reports, collaborations with local extension offices, and partnerships with the National Weather Service cooperative observer network. As part of a NASA Citizen Science for Earth Systems proposal award, a research and applications team from Marshall Space Flight Center, the University of Alabama in Huntsville, and collaborators within the NWS have developed a prototype smartphone application focused on the collection of citizen science observations of crop health and drought impacts, along with development of innovative low-cost soil moisture sensors to supplement subjective assessments of local soil moisture conditions. Observations provided by citizen scientists include crop type and health, phase of growth, soil moisture conditions, irrigation status, along with an optional photo and comment to provide visual confirmation and other details. In exchange for their participation, users of the app also have access to unique land surface modeling data sets produced at MSFC such as the NASA Land Information System soil moisture and climatology/percentile products from the Short-term Prediction Research and Transition (SPoRT) Center, assessments of vegetation health and stress from NASA and NOAA remote sensing platforms (e.g. MODIS/VIIRS), outputs from a crop stress model developed at the University of Alabama in Huntsville, recent rainfall estimates from the NOAA/NWS network of ground-based weather radars, and other observations made

    As a participant in PolarTrec, I joined the crew of NASA's Operation IceBridge in Greenland for the month of April 2017. As an active member of the team I learned the ins and outs of field research, and I learned about the work done by Operation IceBridge. As a result of participating in this project, I grew as a teacher and a scientist. I took my experiences and shared them with my classroom through stories, pictures, videos, and my lesson plans. By seeing the Artic through my experiences the class became enraptured by the subject matter. I was no longer talking about a distant or abstract place instead I was talking about an experience. This enabled my students to take an active part in the discussion and to feel like the cryosphere was part of their life too. Not only did I learn about the science but I leaned about logistics of field research. I reached out to my community and local communications outlets before and after my trip to Greenland to familiarize whomever I could connect with about my experience. I contacted a local news station and they did an interview with me about my trip. I emailed a local newspaper about my trip and was interviewed before I left and after I returned. Due to the newscast, I was contacted by my college sorority and was interviewed for the sorority's national newsletter which is distributed throughout the United States. Each connection helped to spread the word. I'm continuing to spread the word by volunteering to present my experience to schools throughout Broward County in Florida. I've already connected with teachers and schools to set up my presentation in the calendar. Having these types of experiences is critical for teachers to continue their growth within the scientific field and education. Effective teachers are those not constrained by the walls of their classroom. Having the opportunity to work with scientists and do research in the field has expanded my horizons. The people I met I am still in contact with and I am
