    "It all went very smoothly, " said Jonh Dodsworth, ESOC's flight operations Director, "We had the option to continue checks on 26 October in case of difficulty, but we don't need to. That's good news". ESOC established connection with the Huygens probe at 10:09 hrs, Central European Time on 23 October, using NASA's link to Cassini. Thanks to ESOC's new flight operations system, engineers and scientists responsible for the mission could check quite quickly that Huygens is alive and well in all respects. ESA's project management team, and representatives of the contractors who built Huygens, were able to report that the engineering system and subsystems are all performing nominally. The principal investigators from Europe and the USA, in charge of the six instruments on Huygens, were also present for the tests. Each experiment was checked for functionality : * HASI to analyse Titan's atmosphere and weather - DWE to measure wind speeds during the descent - GCMS to analyse chemical compounds on Titan - ACP to break down aerosols for chemical analysis - DISR to produce images and spectra of Titan - SSP to determine the nature of Titan's surface. "Six experiments, six green lights", said Jean-Pierre Lebreton, ESA's project scientist. The project manager for Huygens is Hamid Hassan. In Darmstadt he too declared himself pleased with the check-out of the Huygens systems, subsystems and instruments. "We will now let Huygens go back to sleep, except for the planned six monthly checkouts" Hassan said. "The probe will remain in that condition for the seven-year journey to Saturn. But we now have every reason to expect a successful outcome to this unprecedented mission".

    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.

    What is it? Have you ever tried to electrocute a hot dog? Wondered how to make a robot out of a toothbrush, watch battery and phone-pager motor? Seen a cantaloupe melon and thought, "Hmm, I could make this look like the Death Star from the original Star Wars films"? If you have not, but you would like to - preferably as soon as you can find a pager motor - then this is the site for you. The Evil Mad Scientist Project (EMSP) blog is packed full of ideas for unusual, silly and frequently physics-related creations that bring science out of the laboratory and into kitchens, backyards and tool sheds.

    environments ever attempted by a man-made object. On this pass, the Huygens touchdown site will be visible at around 167 degrees East and 10.7 degrees South on the sunlit face of Titan before reaching the point of closest approach. Data from the imaging and radar instrumentation on board Cassini-Huygens should provide a tantalising idea of what the surface of Titan could be like. A second view of the Huygens touchdown site will be possible on the second close fly-by in December. Jean-Pierre Lebreton, ESA’s Huygens Mission Manager and Project Scientist, said: “This first close-up look at Titan should enable us to find out just how precisely our atmospheric models fit with the real situation and of course we are excited about the prospect of discovering just what type of surface the Huygens probe could impact on early next year.” Today’s fly-by will also be looking at other aspects of Titan which, although it is the second largest moon in the Solar System after Jupiter’s Ganymede, we know relatively little about. The instruments on board the Cassini orbiter will be looking at the surface characteristics, atmospheric properties and interactions with Saturn’s magnetosphere. Huygens is dormant during the fly-by. The first images are expected at 03:30 CEST on 28 October. However, at the point of closest approach, Titan will have an apparent size far exceeding the field of view of the Cassini orbiter’s narrow-angle camera. Details below a 100-metre resolution may be seen if the camera can pierce the haze and fog. Spectacular multicolour images at 1-2 kilometre resolution are also anticipated from the Visual Infrared and Mapping Spectrometer and may reveal details about Titan surface structure and composition. However, the excitement does not stop after 26 October. On 28 October, at about 12:30 CEST, there is a close encounter with Tethys, another of the significant moons of Saturn. Tethys is a ball of solid ice about 1060 kilometres in diameter which orbits Saturn at a

    This is a study of the British scientific mission to Los Alamos, New Mexico, from 1943 to 1947, and the impact it had on the early history of the atomic age. In the years following the Manhattan Project and the production of the world's first atomic explosion in 1945, the British contribution to the Project was played down or completely ignored leaving the impression that all the atomic scientists had been American. However, the two dozen or so British scientists contributed crucially to the development of the atomic bomb. First, the initial research and reports of British scientists convinced American scientists that an atomic weapons could be constructed before the likely end of hostilities. Secondly their contribution insured the bomb was available in the shortest possible time. Also, because these scientists became involved in post-war politics and in post-war development of nuclear power, they also helped forge the nuclear boundaries of the mid-twentieth century. (UK)

    The project scientists is in a position which rates very high in terms of behavioral study recommendations. His influence over objectives is generally considered to be important. He is highly autonomous in a moderately coordinated environment. He has diverse managerial and technical functions and the performance of these functions require him to grow beyond his role as an experimenter. However, the position within the line organization for those interviewed is also very stimulating, rating almost as high by the same criteria. The role of project scientist may not be the dominant means of professional growth for the experienced scientific investigators. The influence which the project scientist exerts on the project and the stimulation of that position for him are determined largely by his position outside the defined project scientist role. The role of the project scientist is changing because the environment of those who become project scientists is changing.

  7. The Manhattan Project and its Effects on American Women Scientists

    There have been many detailed historical accounts of the Manhattan Project, but few have recognized the technical role women scientists and engineers crucially played in the Project's success. Despite their absence from these prominent accounts, recent studies have revealed that, in fact, women participated in every non-combat operation associated with the Manhattan Project. With such extensive participation of women and such a former lack of historical attention upon them, little analysis has been done on how the Manhattan Project might have influenced the prospectus of women scientists after the war. This talk has two aims: 1) to recount some of the technical and scientific contributions of women to the Manhattan Project, and 2) to examine what effects these contributions had on the women's careers as scientists. In other words, I intend offer a preliminary explanation of the extent to which the Manhattan Project acted both as a boon and as a detriment to American women scientists. And finally, I will address what this historical analysis could imply about the effects of current efforts to recruit women into science.

    After nearly 7 years and a 3.5-billion-km, circuitous journey from Earth, the $3-billion Cassini-Huygens mission to Saturn and Titan-an international effort by NASA, the European Space Agency, and the Italian Space Agency-now is just days away from its critical Saturn orbit insertion. Scheduled for 30 June, this will begin the 4-years part of the mission to study the Saturnian system. At a 3 June briefing at NASA headquarters in Washington, D.C., Robert Mitchell, the Cassini program manager with the Jet Propulsion Laboratory in Pasadena, California, said that scientists involved with the program are feeling excited, relieved, and also a bit anxious as the Cassini-Huygens spacecraft draws near to the ringed planet and its system.

    In 2005, the Huygens Probe gave us a snapshot of a world tantalizingly like our own, yet frozen in its evolution on the threshold of life. The descent under parachute, like that of Huygens in 2005, is happening again, but this time in the Saturn-cast twilight of winter in Titan's northern reaches. With a pop, the parachute is released, and then a muffled splash signals the beginning of the first floating exploration of an extraterrestrial sea-this one not of water but of liquid hydrocarbons. Meanwhile, thousands of miles away, a hot air balloon, a "montgolfiere," cruises 6 miles above sunnier terrain, imaging vistas of dunes, river channels, mountains and valleys carved in water ice, and probing the subsurface for vast quantities of "missing" methane and ethane that might be hidden within a porous icy crust. Balloon and floater return their data to a Titan Orbiter equipped to strip away Titan's mysteries with imaging, radar profiling, and atmospheric sampling, much more powerful and more complete than Cassini was capable of. This spacecraft, preparing to enter a circular orbit around Saturn's cloud-shrouded giant moon, has just completed a series of flybys of Enceladus, a tiny but active world with plumes that blow water and organics from the interior into space. Specialized instruments on the orbiter were able to analyze these plumes directly during the flybys. Titan and Enceladus could hardly seem more different, and yet they are linked by their origin in the Saturn system, by a magnetosphere that sweeps up mass and delivers energy, and by the possibility that one or both worlds harbor life. It is the goal of the NASA/ESA Titan Saturn System Mission (TSSM) to explore and investigate these exotic and inviting worlds, to understand their natures and assess the possibilities of habitability in this system so distant from our home world. Orbiting, landing, and ballooning at Titan represent a new and exciting approach to planetary exploration. The TSSM mission

  12. Huygens landing site to be named after Hubert Curien

    Science.gov (United States)

    2007-03-01

    The naming ceremony for the Huygens landing site, which will be known as the "Hubert Curien Memorial Station", will be held at ESA’s Headquarters on 14 March, in the presence of ESA Council delegates and of Professor Curien’s wife, Mrs Perrine Curien, and one of their sons. Media interested in attending are invited to submit the reply form below. Huygens' landing on Saturn’s largest moon in January 2005 represented one of the greatest successes achieved by humankind in the history of space exploration. The part played by ESA, in cooperation with NASA and the Italian Space Agency (ASI), was made possible thanks to the commitment of a man who, for several decades, worked to promote and strengthen the role of scientific research in his home country - France - and in Europe. Among his numerous responsibilities, Hubert Curien was French Minister of Research and Space under four Prime Ministers. As Chairman of the ESA Council from 1981 to 1984, Professor Curien played a crucial part in setting up ESA's former long-term science programme, "Horizon 2000", which included the Huygens mission among its projects. Professor Roger Bonnet, current President of COSPAR, and former ESA Director of Science (1983-2001), commented: "Curien’s diplomatic skills were hugely influential in bringing about the birth of European space science. In 1985, his support was pivotal when the European ministers had to decide how to build a solid space science programme and ensure that it would be financially sustainable in the long term." "ESA's present science programme, Cosmic Vision, draws on the heritage left by Hubert Curien", said Professor David Southwood, ESA's current Director of Science. "He encouraged cooperation between nations in the belief that space research is fundamental to the progress and welfare of a knowledge-based society like ours. He also promoted the concept of long-term planning", he continued. "It would seem almost inconceivable today to initiate any space venture

    From the very beginning of their career, it is important for Early Career Scientists (ECS) to develop project management skills to be able to organise their research efficiently. ECS are often in charge of specific tasks within their projects or for their teams. However, without specific training or tools, the successful completion of these assignments will depend entirely on the organisational skills of individual researchers. ECS are thus facing "sink-or-swim" situations, which can be either instructive or disastrous for their projects. Here we provide experience-based tips from fellow ECS that can help manage various project activities, including: 1. Communication with supervisors and peers 2. Lab management 3. Field trips (e.g., oceanographic campaigns) 4. Internships and collaborations with other institutions 5. Literature/background research 6. Conference convening These are potential "life buoys" for ECS, which will help them to carry out these tasks efficiently and successfully.

    "Cassini At Saturn - Huygens Results" will bring the story of the Cassini-Huygens mission and their joint exploration of the Saturnian system right up to date. Cassini is due to enter orbit around Saturn on the 1 July 2004 and the author will have 8 months of scientific data available for review, including the most spectacular images of Saturn, its rings and satellites ever obtained by a space mission. As the Cassini spacecraft approached its destination in spring 2004, the quality of the images already being returned by the spacecraft clearly demonstrate the spectacular nature of the close-range views that will be obtained. The book will contain a 16-page colour section, comprising a carefully chosen selection of the most stunning images to be released during the spacecraft's initial period of operation. The Huygens craft will be released by Cassini in December 2004 and is due to parachute through the clouds of Saturn's largest moon, Titan, in January 2005.

  17. The PACA Project: When Amateur Astronomers Become Citizen Scientists

    2014-12-01

    The Pro-Am Collaborative Astronomy (PACA) project evolved from the observational campaign of C/2012 S1 or C/ISON in 2013. Following the success of the professional-amateur astronomer collaboration in scientific research via social media, it is now implemented in other comet observing campaigns. While PACA identifies a consistent collaborative approach to pro-am collaborations, given the volume of data generated for each campaign, new ways of rapid data analysis, mining access and storage are needed. Several interesting results emerged from the synergistic inclusion of both social media and amateur astronomers: (1) the establishment of a network of astronomers and related professionals, that can be galvanized into action on short notice to support observing campaigns; (2) assist in various science investigations pertinent to the campaign; (3) provide an alert-sounding mechanism should the need arise; (4) immediate outreach and dissemination of results via our media/blogger members; (5) provide a forum for discussions between the imagers and modelers to help strategize the observing campaign for maximum benefit. In 2014, two new comet observing campaigns involving pro-am collaborations have been initiated: (1) C/2013 A1 (C/SidingSpring) and (2) 67P/Churyumov-Gerasimenko (CG), target for ESA/Rosetta mission. The evolving need for individual customized observing campaigns has been incorporated into the evolution of PACA portal that currently is focused on comets: from supporting observing campaigns of current comets, legacy data, historical comets; interconnected with social media and a set of shareable documents addressing observational strategies; consistent standards for data; data access, use, and storage, to align with the needs of professional observers. The integration of science, observations by professional and amateur astronomers, and various social media provides a dynamic and evolving collaborative partnership between professional and amateur astronomers

  19. The Cassini-Huygens mission

    CERN Document Server

    The joint NASA-ESA Cassini-Huygens mission promises to return four (and possibly more) years of unparalleled scientific data from the solar system’s most exotic planet, the ringed, gas giant, Saturn. Larger than Galileo with a much greater communication bandwidth, Cassini can accomplish in a single flyby what Galileo returned in a series of passes. Cassini explores the Saturn environment in three dimensions, using gravity assists to climb out of the equatorial plane to look down on the rings from above, to image the aurora and to study polar magnetospheric processes such as field-aligned currents. Since the radiation belt particle fluxes are much more benign than those at Jupiter, Cassini can more safely explore the inner regions of the magnetosphere. The spacecraft approaches the planet closer than Galileo could, and explores the inner moons and the rings much more thoroughly than was possible at Jupiter. This book is the second volume, in a three volume set, that describes the Cassini/Huygens mission. Thi...

    CosmoQuest launched as a citizen science portal in January 2012 and has since expanded to include three projects in planetary surface mapping, one completed project searching for KBOs, and several more on the way with various astrophysical science goals. We take a close look at how our users move through the site, how much time they spend on various tasks, project retention rate, and how many use multiple projects on the site. We are also piloting a citizen science motivation survey given to random site users to find out why citizen scientists join new projects and continue to participate. This is part of a larger project using online and real-life interactions to study citizen scientist behaviors, motivations, and learning with a goal of building better community with researchers, volunteers, educators, and developers.

  1. Assessment of the Jabiluka Project - Report of the Supervising Scientist to the World heritage Committee. Supervising Scientist report 138

    International Nuclear Information System (INIS)

    Johnston, A.; Prendergast, J.B.

    1999-01-01

    This report has been prepared in response to the request of the World Heritage Committee that the Supervising Scientist conduct a full review of scientific issues raised by the Committee's Mission to Kakadu National Park in October-November 1998. Perceived scientific uncertainty with respect to these issues had led to the Mission's conclusion that the natural values of Kakadu are threatened by the Jabiluka project. This detailed review has demonstrated that there were a number of weaknesses in the hydrological modelling presented by ERA in the EIS and the PER. Accordingly, a number of recommendations have been made which should be implemented by ERA in completing the detailed design of the Jabiluka project. On the other hand, the review has demonstrated quite clearly that, if the design of the water management system proposed by ERA in the PER had been implemented, the risk to the wetlands of Kakadu National Park, and the risk of radiation exposure to people of the region would have been extremely low. This conclusion is valid even in extreme circumstances leading to the complete failure of the structure of the water retention pond at Jabiluka. Copyright (2000) Commonwealth of Australia

  2. The how and why of societal publications for citizen science projects and scientists

    2014-05-01

    In the scientific community, the importance of communication to society is often underestimated. Scientists and scientific organisations often lack the skills to organise such communication effectively. The Dutch citizen science phenology network Nature's Calendar has been successful in communicating to the general public via numerous newspaper articles, television appearances, presentations, websites and social media. We refer to these publications as societal publications. Due to active communication to mass media, we frequently reach millions of people. This communication helped us to involve thousands of volunteers in recording the timing of phenological events like the start of flowering, leaf unfolding and bird migration, but also several health-related events like hay fever symptoms and tick bites. In this paper, we analyse and present our experiences with the Nature's Calendar project regarding societal publications. Based on this analysis, we explain the importance of societal publications for citizen science projects and scientists in general, and we show how scientists can increase the newsworthiness of scientific information and what factors and activities can increase the chances of media paying attention to this news. We show that societal publications help phenological networks by facilitating the recruitment, retention and instruction of observers. Furthermore, they stimulate the generation of new ideas and partners that lead to an increase in knowledge, awareness and behavioural change of the general public or specific stakeholders. They make projects, and scientists involved, better known to the public and increase their credibility and authority. Societal publications can catalyse the production of new publications, thereby enforcing the previous mentioned points.

    2015-12-01

    Student to Scientist (S2S), provides pathways for observational and research tools for K-12 and undergraduate students to improve science proficiency through conducting real scientific observations. Our approach lies in the integration of professional and amateur astronomers, educators, students, and communicators to identify multiple paths for the student to become a scientist. I report on the ensuing project, also known as the PACA Project, which is an ecosystem of various activities that take advantage of the social media and immediate connectivity amongst amateur astronomers worldwide and that can be galvanized to participate in a given observing campaign. The PACA Project has participated in organized campaigns such as NASA Comet ISON Observing Campaign in 2013; NASA Comet Integrated Observations Campaign to observe Comet Siding Spring as it flew by very close to Mars on 19 October 2014. Currently the PACA Project is involved in the Ground-based Amateur campaign to observer ESA/Rosetta mission's target, 67P/Churyumov-Gerasimenko (CG) that is en route to its perihelion on 13 August 2015 (at the time of abstract submission). The PACA Project provides access to the professional community and the student/educator and informal/public communities via various social media like Facebook, Twitter, Flickr, Pinterest, Vimeo, Google+. With the popularity of mobile platforms and instant connections with other peers globally, the multi-faceted social universe has become a vital part of engagement of multiple communities. The PACA project currently has initiated a Comet Tails and Disconnection Events campaign to relate to the changing solar wind conditions. Other PACA projects include Saturn Solstice 2017 and outreach projects with Astroproject (India). These and other citizen-science enabled activities and their integration with S2S project will be discussed.

This communication helped us to involve thousands of volunteers in recording the timing of phenological events like the start of flowering, leaf unfolding and bird migration, but also several health-related events like hay fever symptoms and tick bites. In this paper, we analyse and present our experiences with the Nature's Calendar project regarding societal publications. Based on this analysis, we explain the importance of societal publications for citizen science projects and scientists in general, and we show how scientists can increase the news worthiness of scientific information and what factors and activities can increase the chances of media paying attention to this news. We show that societal publications help phenological networks by facilitating the recruitment, retention and instruction of observers. Furthermore, they stimulate the generation of new ideas and partners that lead to an increase in knowledge, awareness and behavioural change of the general public or specific stakeholders. They make projects, and scientists involved, better known to the public and increase their credibility and authority. Societal publications can catalyse the production of new publications, thereby enforcing the previous mentioned points.

    The PISCES Project (Partnerships Involving the Scientific Community in Elementary Schools www.sdsa.org/pisces) is an innovative program that brings high quality standards-based elementary science curriculum and hands-on laboratory materials into San Diego County's classrooms. The project is funded by the NSF Graduate Teaching Fellows in K-12 Education (GK-12) program. The project was designed and is administered through cooperation among faculty at San Diego State University and the Science Department of the San Diego County Office of Education. Undergraduate and graduate students enrolled in science programs in San Diego area universities including San Diego State University, California State University San Marcos, and University of California San Diego partner with elementary school teachers. Through this partnership, the scientist brings scientific expertise to the classroom while the teacher delivers the lesson using current pedagogic methods. This is accomplished during a 3 month partnership in which the scientist joins the teacher in the classroom a few days each week to complete professional kit-based curriculum such as that available from FOSS (Full Option Science System) and STC (Science and Technology for Children). The teachers remain in the program for two years during which they have continuous access to the kit-based curriculum as well as two to three partnership cycles. Teachers receive assistance outside of the classroom as well attending professional development institutes three times a year to establish and maintain effective science teaching methods. The San Diego Science Alliance and other community and industry supporters provide the additionalfunding necessary to provide this teacher professional development Currenty, PISCES is present in over 40 schools and is able to provide partnerships to over 100 classrooms each year. In addition to the work done in San Diego, the project has expanded to Barrow, Alaska with plans to expand to La Paz

    The Berkeley Compass Project is a self-formed group of graduate and undergraduate students in the physical sciences at UC Berkeley. Our goals are to improve undergraduate physics education, provide opportunities for professional development, and increase retention of students from populations typically underrepresented in the physical sciences. For students who enter as freshmen, the core Compass experience consists of a summer program and several seminar courses. These programs are designed to foster a diverse, collaborative student community in which students engage in authentic research practices and regular self-reflection. Compass encourages undergraduates to develop an identity as a scientist from the beginning of their university experience.

    For the past 5 years, the MY NASA DATA (MND) project at NASA Langley has developed and adapted tools and materials aimed at enabling student access to real NASA Earth science satellite data. These include web visualization tools including Google Earth capabilities, but also GPS and graphing calculator exercises, Excel spreadsheet analyses, and more. The project team, NASA scientists, and over 80 classroom science teachers from around the country, have created over 85 lesson plans and science fair project ideas that demonstrate NASA satellite data use in the classroom. With over 150 Earth science parameters to choose from, the MND Live Access Server enables scientific inquiry on numerous interconnected Earth and environmental science topics about the Earth system. Teachers involved in the project report a number of benefits, including networking with other teachers nationwide who emphasize data collection and analysis in the classroom, as well as learning about other NASA resources and programs for educators. They also indicate that the MND website enhances the inquiry process and facilitates the formation of testable questions by students (a task that is typically difficult for students to do). MND makes science come alive for students because it allows them to develop their own questions using the same data scientists use. MND also provides educators with a rich venue for science practice skills, which are often overlooked in traditional curricula as teachers concentrate on state and national standards. A teacher in a disadvantaged school reports that her students are not exposed to many educational experiences outside the classroom. MND allows inner city students to be a part of NASA directly. They are able to use the same information that scientists are using and this gives them inspiration. In all classrooms, the MND microsets move students out of their local area to explore global data and then zoom back into their homes realizing that they are a part of the

    It is challenging for many to get a sense of what climate change means as long periods of time are involved - like decades - which can be difficult to grasp. However, there are a number of citizen science based projects, including NEON's Project BudBurst, that provide the opportunity for both learning about climate change and advancing scientific knowledge. In this presentation, we will share lessons learned from Project BudBurst. Project BudBurst is a national citizen science initiative designed to engage the public in observations of phenological (plant life cycle) events and to increase climate literacy. Project BudBurst is important from an educational perspective, but also because it enables scientists to broaden the geographic and temporal scale of their observations. The goals of Project BudBurst are to 1) increase awareness of phenology as an area of scientific study; 2) Increase awareness of the impacts of changing climates on plants at a continental-scale; and 3) increase science literacy by engaging participants in the scientific process. It was important to better understand if and how Project BudBurst is meeting its goals. Specifically, does participation by non-experts advance scientific knowledge? Does participation advance educational goals and outcomes? Is participation an effective approach to advance/enhance science education in both formal and informal settings? Critical examination of Project BudBurst supports advancement of scientific knowledge and realization of educational objectives. Citizen science collected observations and measurements are being used by scientists as evidenced by the increase of such data in scientific publication. In addition, we found that there is a significant increase in educators utilizing citizen science as part of their instruction. Part of this increase is due to the resources and professional development materials available to educators. Working with partners also demonstrated that the needs of both science and

    In recent years, several space science research projects have enlisted the help of large numbers of non-professional volunteers, ``citizen scientists'', to aid in performing tasks that are critical to a project, but require more person-time (or computing time) than a small professional research team can practically perform themselves. Examples of such projects include SETI@home, which uses time from volunteers computers to process radio-telescope observation looking for signals originating from extra-terrestrial intelligences; Clickworkers, which asks volunteers to review images of the surface of Mars to identify craters; Spacewatch, which used volunteers to review astronomical telescopic images of the sky to identify streaks made by possible Near Earth Asteroids; and Stardust@home, which asks volunteers to review ``focus movies'' taken of the Stardust interstellar dust aerogel collector to search for possible impacts from interstellar dust particles. We shall describe these and other similar projects and discuss lessons learned from carrying out such projects, including the educational opportunities they create.

    Many times during the Cassini-Huygens mission to Saturn, propulsive maneuvers must be spaced so closely together that there isn't enough time or workforce to execute the maneuver-related software manually, one subsystem at a time. Automation is required. Automating the maneuver design process has involved close cooperation between teams. We present the contribution from the Navigation system. In scope, this includes trajectory propagation and search, generation of ephemerides, general tasks such as email notification and file transfer, and presentation materials. The software has been used to help understand maneuver optimization results, Huygens probe delivery statistics, and Saturn ring-plane crossing geometry. The Maneuver Automation Software (MAS), developed for the Cassini-Huygens program enables frequent maneuvers by handling mundane tasks such as creation of deliverable files, file delivery, generation and transmission of email announcements, generation of presentation material and other supporting documentation. By hand, these tasks took up hours, if not days, of work for each maneuver. Automated, these tasks may be completed in under an hour. During the cruise trajectory the spacing of maneuvers was such that development of a maneuver design could span about a month, involving several other processes in addition to that described, above. Often, about the last five days of this process covered the generation of a final design using an updated orbit-determination estimate. To support the tour trajectory, the orbit determination data cut-off of five days before the maneuver needed to be reduced to approximately one day and the whole maneuver development process needed to be reduced to less than a week..

    2014-11-01

    In Christiaan Huygens posthumous book, "The Celestial Worlds Discover's" (1698) he lays out an optimistic vision of a universe of various worlds, some populated by beings like ourselves, and even with a few who might be scientists wondering about the same questions. He offers, in essence, a truly modern perspective on planetary physics and astrobiology.He notes that other worlds may have fluids forming clouds and rain, but that these fluids might be different from water, since for example Jupiter and Saturn are far from the sun and this 'water of ours' would be 'liable to frost.' He even speculates that other atmospheres might be thicker than ours, which would be favorable for the locomotion of the 'volatile animals.' Rather germane to present studies of Titan's seas and giant planet interiors, he even wonders if there might be layers of fluids of different densities : "There may also be many forts of Fluids ranged over one another in Rows as it were. The Sea perhaps may have such a fluid lying on it, which tho’ ten times lighter than Water, may be a hundred Time heavier than Air".Huygens considered that mariners on other worlds might use the same pulleys and anchors (noting essentially the universality of function of such devices) yet that other planets might have advantages or disadvantages for any given approach. Indeed, he rues how easy navigation must be on Jupiter and Saturn, having the benefit of so many moons from which Longitude could be determined (a vexing challenge of his day). He even notes that other worlds might have magnetic fields, allowing their sailors to use the compass. As post-Cassini exploration of Titan contemplates a number of vehicle types, from hot air balloons to sailboats which can exploit the thick atmosphere and low gravity of that environment, it is fitting to recall the perspective of Titan's discoverer on other worlds as being similar, but different. The same laws of physics and logic of design apply, but with different

    The Frontier Scientists National Science Foundation project titled Science in Alaska: Using Multimedia to Support Science Education produced research products in several formats: videos short and long, blogs, social media, a computer game, and a pop-up book. These formats reached distinctly different audiences. Internet users, public TV viewers, gamers, schools, and parents & young children were drawn to Frontier Scientists' research in direct and indirect ways. The analytics (our big data) derived from this media broadcast has given us insight into what works, what doesn't, next steps. We have evidence for what is needed to present science as an interesting, vital, and a necessary component for the general public's daily information diet and as an important tool for scientists to publicize research and to thrive in their careers. Collaborations with scientists at several Universities, USGS, Native organizations, tourism organizations, and Alaska Museums promoted accuracy of videos and increased viewing. For example, Erin Marbarger, at Anchorage Museum, edited, and provided Spark!Lab to test parents & child's interest in the pop-up book titled: The Adventures of Apun the Arctic Fox. Without a marketing budget Frontier Scientist's minimum publicity, during the three year project, still drew an audience. Frontier Scientists was awarded Best Website 2016 by the Alaska Press Club, and won a number of awards for short videos and TV programs.

    2015-04-01

    Bridging Science and Society has now become a necessity for scientists to develop new partnerships with local communities and to raise the public interest for scientific activities. The French-Greenlandic educational project called "Angalasut" reflects this desire to create a bridge between science, local people and the general public. This program was set up on the 2012-2013 school year, as part of an international scientific program dedicated to study the interactions between the ocean and glaciers on the western coast of Greenland, in the Uummannaq fjord. Greenlandic and French school children were involved in educational activities, in classrooms and out on the field, associated with the scientific observations conducted in Greenland (glacier flow, ocean chemical composition and circulation, instrumentation...). In Greenland, the children had the opportunity to come on board the scientific sailing boat, and in France, several meetings were organized between the children and the scientists of the expedition. In the small village of Ikerasak, the children interviewed Elders about sea ice evolution in the area. These activities, coupled to the organization of public conferences and to the creation of a trilingual website of the project (French, Greenlandic, English) aimed at explaining why scientists come to study Greenland environment. This was the opportunity for scientists to discuss with villagers who could testify on their changing environment over the past decades. A first step toward a future collaboration between scientists and villagers that would deserve further development... The project Angalasut was also the opportunity for Greenlandic and French school children to exchange about their culture and their environment through Skype communications, the exchange of mails (drawings, shells...), the creation of a society game about European fauna and flora... A meeting in France between the two groups of children is considered, possibly in summer 2015

    K-12 teacher professional development rich in content and pedagogical methods and materials for implementation of STEM concepts in the classroom will enhance teacher preparation and practice, and ultimately student learning is the purpose of the American Meteorological Society (AMS) DataStreme Project. DataStreme Atmosphere, Ocean, and Earth's Climate System (ECS) are offered each fall and spring semester by Local Implementation Teams across the country in coordination with AMS Education Program scientists and educators. Participants may receive 3 tuition-free graduate credits through State University of New York's The College at Brockport upon completion of each course and construction of a Plan of Action for peer-training. Peer training is a key focus of DataStreme. Based on survey results, a DataStreme participant impacts an average of up to 10 other teachers and over 350 students within two years of training. Therefore, the 220 teachers who completed a DataStreme course in fall 2015 will likely reach over 2000 teachers and close to 77,000 students within two years. Further, DataStreme improves teachers' pedagogical abilities. According to the fall 2015 pre-survey of DataStreme ECS participants, approximately 15% of participants rated their pedagogical abilities in the Superior or Exemplary levels (highest rankings). On the post-survey, 59% of participants fell in these categories, clearly highlighting the positive shift. This survey also revealed teachers' ability to use climate-science content to stimulate student interests. The AMS looks to further this success with redevelopment of a previously offered K-12 teacher professional development course focused on water. From 2001-2008, AMS offered DataStreme Water in the Earth System, training 3145 teachers on the global water cycle. AMS is eager to continue helping teachers and students improve their understanding of water processes and overall environmental science literacy.

    2015-01-01

    Cassini-Huygens was the most ambitious and successful space journey ever launched to the outer Solar System. This book examines all aspects of the journey: its conception and planning; the lengthy political processes needed to make it a reality; the engineering and development required to build the spacecraft; its 2.2-billion mile journey from Earth to the Ringed Planet; and the amazing discoveries from the mission. The author traces how the visions of a few brilliant scientists matured, gained popularity, and eventually became a reality. Innovative technical leaps were necessary to assemble such a multifaceted spacecraft and reliably operate it while it orbited a planet so far from our own. The Cassini-Huygens spacecraft design evolved from other deep space efforts, most notably the Galileo mission to Jupiter, enabling the voluminous, paradigm-shifting scientific data collected by the spacecraft.  Some of these discoveries are absolute gems.

    Geoheritage is an effective way of transferring scientific knowledge to non-peer audiences of all types. We present our experience of the Chaîne des Puys and Limagne fault UNESCO World heritage project, which shows how geoheritage can be a very successful communication tool, especially as it draws in the non-peers into the geological process at many levels. First and foremost is the local level, as no geoheritage project can be successful without local participation. Few geological localities on Earth are now devoid of human influence or habitation, and thus those who live and work on sites are the necessary first stage custodians. This means that locals must gain some understanding of their geology in order to appreciate their heritage. As such people tend to have a close relationship with their land, this is often half way done: local land use, customs are often easily integrated with geological knowledge. Once this link exists, communicating ideas that can be useful for management or for dealing with hazards is easier. Sometimes more tricky is communication to visitors, tourists and politicians who do not have such as close link to the landscape. Here, the educational strategy has to be different, with a need for them to learn what the landscape is and how it is managed, and lived in. During the development of the World Heritage Chaîne des Puys and Limagne Fault project the project team has been composed of geoscientists actively working on the area, agronomists local administration (such as natural park and local government members), and landscape specialists. Each has engaged in communication at different levels channelled either through personal contacts, or through more formal means, such as exhibitions, talks, and websites. Scientists have become communicators, and non-peers have begun to see the landscape though a geolologist eyes. A Geological landscape has begun to emerge in the popular perception.

    2017-10-01

    Science communication is becoming an increasingly important part of a scientist's remit, and engaging with primary and secondary schools is one frequently chosen strategy. Here we argue that science communication in schools will be more effective if based on good understanding of the realities of school life, which can be achieved through structured participation and/or collaboration with teachers. For example, the Manchester Fly Facility advocates the use of the fruit fly Drosophila as an important research strategy for the discovery processes in the biomedical sciences. To communicate this concept also in schools, we developed the 'droso4schools' project as a refined form of scientist-teacher collaboration that embraces the expertise and interests of teachers. Within this project, we place university students as teaching assistants in university partner schools to collaborate with teachers and develop biology lessons with adjunct support materials. These lessons teach curriculum-relevant biology topics by making use of the profound conceptual understanding existing in Drosophila combined with parallel examples taken from human biology. By performing easy to implement experiments with flies, we bring living organisms into these lessons, thus endeavouring to further enhance the pupil's learning experience. In this way, we do not talk about flies but rather work with flies as powerful teaching tools to convey mainstream curriculum biology content, whilst also bringing across the relevance of Drosophila research. Through making these lessons freely available online, they have the potential to reach out to teachers and scientists worldwide. In this paper, we share our experiences and strategies to provide ideas for scientists engaging with schools, including the application of the droso4schools project as a paradigm for long-term school engagement which can be adapted also to other areas of science.

    The Cassini-Huygens mission has greatly enhanced our understanding of the Saturn system. Fundamental discoveries have altered our views of Saturn, its retinue of icy moons including Titan, the dynamic rings, and the system's complex magnetosphere. Launched in 1997, the Cassini-Huygens spacecraft spent seven years traveling to Saturn, arriving in July 2004, roughly two years after the northern winter solstice. Cassini has orbited Saturn for 9.5 years, delivering the Huygens probe to its Titan landing in 2005, crossing northern equinox in August 2009, and completing its Prime and Equinox Missions. It is now three years into its 7-year Solstice mission, returning science in a previously unobserved seasonal phase between equinox and solstice. As it watches the approach of northern summer, long-dark regions throughout the system become sunlit, allowing Cassini's science instruments to probe as-yet unsolved mysteries. Key Cassini-Huygens discoveries include icy jets of material streaming from tiny Enceladus' south pole, lakes of liquid hydrocarbons and methane rain on giant Titan, three-dimensional structures in Saturn's rings, and curtain-like aurorae flickering over Saturn's poles. The Huygens probe sent back amazing images of Titan's surface, and made detailed measurements of the atmospheric composition, structure and winds. Key Cassini-Huygens science highlights will be presented. The Solstice Mission continues to provide new science. First, the Cassini spacecraft observes seasonally and temporally dependent processes on Saturn, Titan, Enceladus and other icy satellites, and within the rings and magnetosphere. Second, it addresses new questions that have arisen during the mission thus far, for example providing qualitatively new measurements of Enceladus and Titan that could not be accommodated in the earlier mission phases. Third, it will conduct a close-in mission at Saturn yielding fundamental knowledge about the interior of Saturn. This grand finale of the

    2013-09-01

    The Cassini-Huygens mission has brought many informations about Titan that can be used to infer its interior structure: the gravity field coefficients (up to degree 3, [1]), the surface shape (up to degree 6, [2]), the tidal Love number [1], the electric field [3], and the orientation of its rotation axis [4]. The measured obliquity and gravity perturbation due to tides, as well as the electric field, are lines of evidence for the presence of an internal global ocean beneath the ice surface of Titan [5,1,3]. The observed surface shape and gravity can be used to further constrain the structure of the ice shell above the internal ocean. The presence of a significant topography associated with weak gravity anomalies indicates that deflections of internal interface or lateral density variations may exist to compensate the topography. To assess the sources of compensation, we consider interior models including interface deflections and/or density variations, which reproduces simultaneously the surface gravity and long-wavelength topography data [6]. Furthermore, in order to test the long-term mechanical stability of the internal mass anomalies, we compute the relaxation rate of each internal interface in response to surface mass load. We show that the topography can be explained either by defections of the ocean/ice interface or by density variations in an upper crust [6]. For non-perfectly compensated models of the outer ice shell, the present-day structure is stable only for a conductive layer above a relatively cold ocean (for bottom viscosity > 1016 Pa.s, T residual gravity anomalies. The existence of mass anomalies in the rocky core is a most likely explanation. However, as the observed geoid and topography are mostly sensitive to the lateral structure of the outer ice shell, no information can be retrieved on the ice shell thickness, ocean density and/or size of the rocky core. Constraints on these internal parameters can be obtained from the tidal Love number and

    Facilitating not only the mastery of sophisticated subject matter, but also the development of process skills is an ongoing challenge in teaching any introductory undergraduate course. To accomplish this goal in a sophomore-level introductory cell biology course, I require students to work in groups and complete several mock experiential research projects that imitate the professional activities of the scientific community. I designed these projects as a way to promote process skill development within content-rich pedagogy and to connect text-based and laboratory-based learning with the world of contemporary research. First, students become familiar with one primary article from a leading peer-reviewed journal, which they discuss by means of PowerPoint-based journal clubs and journalism reports highlighting public relevance. Second, relying mostly on primary articles, they investigate the molecular basis of a disease, compose reviews for an in-house journal, and present seminars in a public symposium. Last, students author primary articles detailing investigative experiments conducted in the lab. This curriculum has been successful in both quarter-based and semester-based institutions. Student attitudes toward their learning were assessed quantitatively with course surveys. Students consistently reported that these projects significantly lowered barriers to primary literature, improved research-associated skills, strengthened traditional pedagogy, and helped accomplish course objectives. Such approaches are widely suited for instructors seeking to integrate process with content in their courses.

    Huygens crater is a well preserved peak ring structure on Mars centered at 13.5 deg S, 55.5 deg E in the Noachian highlands between Terras Tyrrhena and Sabaea near the NW rim of Hellas basin. With a diameter of approximately 470 km, it uplifted and exhumed pre-Noachian crustal materials from depths greater than 25 km, penetrating below the thick, ubiquitous layer of Hellas ejecta. In addition, Huygens served as a basin for subsequent aqueous activity, including erosion/deposition by fluvial valley networks and subsurface alteration that is now exposed by smaller impacts. Younger mafic-bearing plains that partially cover the basin floor and surrounding intercrater areas were likely emplaced by later volcanism.

    We propose a Huygens source unit cell to develop an ultrathin low-reflection metasurface, which could provide extreme controls of phases of the transmitted waves. Both electric and magnetic currents are supported by the proposed unit cell, thus leading to highly efficient and full controls of phases. The coupling between electric and magnetic responses is negligible, which will significantly reduce the difficulty of design. Since the unit cell of metasurface is printed on two bonded boards, the fabrication process is simplified and the thickness of metasurface is reduced. Based on the proposed unit cell, a beam-refracting metasurface with low-reflection is designed and manufactured. Both near-field and far-field characteristics of the beam-refracting metasurface are investigated by simulations and measurements, which indicate that the proposed Huygens metasurface performs well in controlling electromagnetic waves

    The Berkeley Compass Project is a self-formed group of graduate and undergraduate students in the physical sciences at the University of California, Berkeley. Its goals are to improve undergraduate physics education, provide opportunities for professional development, and increase retention of students from populations underrepresented in the physical sciences. For undergraduate students, the core Compass experience consists of a summer program and several seminar courses. These programs are designed to foster a diverse, collaborative student community in which students engage in authentic research practices and regular self-reflection. Graduate students, together with upper-level undergraduates, design and run all Compass programs. Compass strives to incorporate best practices from the science education literature. Experiences in Compass leave participants poised to be successful students researchers, teachers, and mentors.

    The SOAP (Study of Open Access Publishing) project has run a large-scale survey of the attitudes of researchers on, and the experiences with, open access publishing. Around forty thousands answers were collected across disciplines and around the world, showing an overwhelming support for the idea of open access, while highlighting funding and (perceived) quality as the main barriers to publishing in open access journals. This article serves as an introduction to the survey and presents this and other highlights from a preliminary analysis of the survey responses. To allow a maximal re-use of the information collected by this survey, the data are hereby released under a CC0 waiver, so to allow libraries, publishers, funding agencies and academics to further analyse risks and opportunities, drivers and barriers, in the transition to open access publishing.

    The Huygens Doppler Wind Experiment (DWE) achieved its primary scientific goal: the derivation of Titan's vertical wind profile from the start of Probe descent to the surface. The carrier frequency of the ultra-stable Huygens radio signal at 2040 MHz was recorded using special narrow-band receivers at two large radio telescopes on Earth: the Green Bank Telescope in West Virginia and the Parkes Radio Telescope in Australia. Huygens drifted predominantly eastward during the parachute descent, providing the first in situ confirmation of Titan's prograde super-rotational zonal winds. A region of surprisingly weak wind with associated strong vertical shear reversal was discovered within the range of altitudes from 65 to 100 km. Below this level, the zonal wind subsided monotonically from 35 m/s to about 7 km, at which point it reversed direction. The vertical profile of the near-surface winds implies the existence of a planetary boundary layer. Recent results on Titan atmospheric circulation within the context of the DWE will be reviewed.

  16. Huygens begins its final journey into the unknown

    Science.gov (United States)

    2004-12-01

    “Today’s release is another successful milestone in the Cassini/Huygens odyssey”, said Dr David Southwood, ESA’s director of science programmes. “This was an amicable separation after seven years of living together. Our thanks to our partners at NASA for the lift. Each spacecraft will now continue on its own but we expect they’ll keep in touch to complete this amazing mission. Now all our hopes and expectations are focused on getting the first in-situ data from a new world we’ve been dreaming of exploring for decades”. Final stage of a 7-year odyssey The Cassini/Huygens mission, jointly developed by NASA, ESA and the Italian space agency (ASI), began on 15 October 1997, when the composite spacecraft were launched from Cape Canaveral, Florida, atop a Titan 4B/Centaur vehicle. Together, the two probes weighed 5548 kg at launch and became the largest space mission ever sent to the outer planets. To gain sufficient velocity to reach Saturn, they had to conduct four gravity-assist manoeuvres by flying twice by Venus, once by the Earth and once by Jupiter. On 1 July Cassini/Huygens eventually became the first spacecraft to enter an orbit around Saturn. On 17 December, while on its third orbit around the ringed planet, the Cassini orbiter performed a manoeuvre to enter a controlled collision trajectory towards Titan. As planned, a fine tuning of the trajectory took place on 22 December to place Huygens on its nominal entry trajectrory. While Huygens will remain on this trajectory till it plunges into Titan’s atmosphere on 14 January, the orbiter will perform a deflection manoeuvre on 28 December to avoid crashing onto the moon. Today’s separation was achieved by the firing of pyrotechnic devices. Under the action of push-off springs, ramps and rollers, the probe was released at a relative velocity of about 0.3 m/s with a spin rate of 7 rpm. Telemetry data confirming the separation were collected by NASA’s Deep Space Network stations in Madrid, Spain

    In 1690, Christiaan Huygens (1629-1695) published Traité de la Lumière, containing his renowned wave theory of light. It is considered a landmark in seventeenth-century science, for the way Huygens mathematized the corpuscular nature of light and his probabilistic conception of natural knowledge. This book discusses the development of Huygens' wave theory, reconstructing the winding road that eventually led to Traité de la Lumière. For the first time, the full range of manuscript sources is taken into account. In addition, the development of Huygens' thinking on the nature of light is put in t

    In the Virtual Observatory (VO), software tools will perform the functions that have traditionally been performed by physical observatories and their instruments. These tools will not be adjuncts to VO functionality but will make up the very core of the VO. Consequently, the tradition of observatory and system independent tools serving a small user base is not valid for the VO. For the VO to succeed, we must improve software collaboration and code sharing between projects and groups. A significant goal of the Scientist's Expert Assistant (SEA) project has been promoting effective collaboration and code sharing among groups. During the past three years, the SEA project has been developing prototypes for new observation planning software tools and strategies. Initially funded by the Next Generation Space Telescope, parts of the SEA code have since been adopted by the Space Telescope Science Institute. SEA has also supplied code for the SIRTF (Space Infrared Telescope Facility) planning tools, and the JSky Open Source Java library. The potential benefits of sharing code are clear. The recipient gains functionality for considerably less cost. The provider gains additional developers working with their code. If enough users groups adopt a set of common code and tools, de facto standards can emerge (as demonstrated by the success of the FITS standard). Code sharing also raises a number of challenges related to the management of the code. In this talk, we will review our experiences with SEA--both successes and failures, and offer some lessons learned that might promote further successes in collaboration and re-use.

    1991-01-01

    As part of Phase 4 of the NASA/DoD Aerospace Knowledge Diffusion Research Project, two pilot studies were conducted that investigated the technical communications practices of Israeli and U.S. aerospace engineers and scientists. Both studies had the same five objectives: first, to solicit the opinions of aerospace engineers and scientists regarding the importance of technical communications to their profession; second, to determine the use and production of technical communications by aerospace engineers and scientists; third, to seek their view about the appropriate content of an undergraduate course in technical communications; fourth, to determine aerospace engineers' and scientists' use of libraries, technical information centers, and on-line databases; and fifth, to determine the use and importance of computer and information technology to them. A self-administered questionnaire was mailed to randomly selected U.S. aerospace engineers and scientists who are working in cryogenics, adaptive walls, and magnetic suspension. A slightly modified version was sent to Israeli aerospace engineers and scientists working at Israel Aircraft Industries, LTD. Responses of the Israeli and U.S. aerospace engineers and scientists to selected questions are presented in this paper.

    It has been suggested that it is possible to replace printed circuit boards with a Huygens' box (HB) representation obtained from a near-field scan in simulation of far-fields from an apparatus. However, the surface equivalence theorem requires that the environment outside HB is the same in the n...... caused by violating the surface equivalence theorem can be lower than 2 dB. It is also demonstrated that if the printed circuit board is galvanically connected to the enclosure, the near-field scan must be performed under same conditions....

    Full Text Available Temperature variations of Titan's upper atmosphere due to the plasma interaction of the satellite with Saturn's magnetosphere and Titan's high altitude monomer haze particles can imply an offset of up to ±30K from currently estimated model profiles. We incorporated these temperature uncertainties as an offset into the recently published Vervack et al. (2004 (Icarus, Vol. 170, 91-112 engineering model and derive extreme case (i.e. minimum and maximum profiles temperature, pressure, and density profiles. We simulated the Huygens probe hypersonic entry trajectory and obtain, as expected, deviations of the probe trajectory for the extreme atmosphere models compared to the simulation based on the nominal one. These deviations are very similar to the ones obtained with the standard Yelle et al. (1997 (ESA SP-1177 profiles. We could confirm that the difference in aerodynamic drag is of an order of magnitude that can be measured by the probe science accelerometer. They represent an important means for the reconstruction of Titan's upper atmospheric properties. Furthermore, we simulated a Cassini low Titan flyby trajectory. No major trajectory deviations were found. The atmospheric torques due to aerodynamic drag, however, are twice as high for our high temperature profile as the ones obtained with the Yelle maximum profile and more than 5 times higher than the worst case estimations from the Cassini project. We propose to use the Cassini atmospheric torque measurements during its low flybys to derive the atmospheric drag and to reconstruct Titan's upper atmosphere density, pressure, and temperature. The results could then be compared to the reconstructed profiles obtained from Huygens probe measurements. This would help to validate the probe measurements and decrease the error bars.

    Doyle, Thomas W.

    2015-01-01

    Coastal wetlands of the Southeastern United States are undergoing retreat and migration from increasing tidal inundation and saltwater intrusion attributed to climate variability and sea-level rise. Much of the literature describing potential sea-level rise projections and modeling predictions are found in peer-reviewed academic journals or government technical reports largely suited to reading by other Ph.D. scientists who are more familiar or engaged in the climate change debate. Various sea-level rise and coastal wetland models have been developed and applied of different designs and scales of spatial and temporal complexity for predicting habitat and environmental change that have not heretofore been synthesized to aid natural resource managers of their utility and limitations. Training sessions were conducted with Federal land managers with U.S. Fish and Wildlife Service, National Park Service, and NOAA National Estuarine Research Reserves as well as state partners and nongovernmental organizations across the northern Gulf Coast from Florida to Texas to educate and to evaluate user needs and understanding of concepts, data, and modeling tools for projecting sea-level rise and its impact on coastal habitats and wildlife. As a result, this handbook was constructed from these training and feedback sessions with coastal managers and biologists of published decision-support tools and simulation models for sea-level rise and climate change assessments. A simplified tabular context was developed listing the various kinds of decision-support tools and ecological models along with criteria to distinguish the source, scale, and quality of information input and geographic data sets, physical and biological constraints and relationships, datum characteristics of water and land elevation components, utility options for setting sea-level rise and climate change scenarios, and ease or difficulty of storing, displaying, or interpreting model output. The handbook is designed

    In the fall of 1991, through the coordinating efforts of the University of New Mexico and Los Alamos National Laboratory, the Pilot Project on Women and Science was initiated as a year-long study of women scientists at both the university and the laboratory. Its purpose was to gather information directly from women scientists in an attempt to analyze and make recommendations concerning the professional and cultural environment for women in the sciences. This report is an initial attempt to understand the ways in which women scientists view themselves, their profession, and the scientific culture they inhabit. By recording what these women say about their backgrounds and educational experiences, their current positions, the difficult negotiations many have made between their personal and professional lives, and their relative positions inside and outside the scientific community, the report calls attention both to the individual perspectives offered by these women and to the common concerns they share.

    The entry of the Cassini-Huygens spacecraft into orbit around Saturn in July 2004 marked the start of a golden era in the exploration of Titan, Saturn's giant moon. During the Prime Mission (2004-2008), ground-breaking discoveries were made by the Cassini orbiter including the equatorial dune fields (flyby T3, 2005), northern lakes and seas (T16, 2006), and the large positive and negative ions (T16 & T18, 2006), to name a few. In 2005 the Huygens probe descended through Titan's atmosphere, taking the first close-up pictures of the surface, including large networks of dendritic channels leading to a dried-up seabed, and also obtaining detailed profiles of temperature and gas composition during the atmospheric descent. The discoveries continued through the Equinox Mission (2008-2010) and Solstice Mission (2010-2017) totaling 127 targeted flybys of Titan in all. Now at the end of the mission, we are able to look back on the high-level scientific questions from the start of the mission, and assess the progress that has been made towards answering these. At the same time, new scientific questions regarding Titan have emerged from the discoveries that have been made. In this paper we review a cross-section of important scientific questions that remain partially or completely unanswered, ranging from Titan's deep interior to the exosphere. Our intention is to help formulate the science goals for the next generation of planetary missions to Titan, and to stimulate new experimental, observational and theoretical investigations in the interim.

    Hagan, Wendy L.

    Project G.R.O.W. is an ecology-based research project developed for high school biology students. The curriculum was designed based on how students learn and awareness of the nature of science and scientific practices so that students would design and carry out scientific investigations using real data from a local coastal wetland. This was a scientist-teacher collaboration between a CSULB biologist and high school biology teacher. Prior to implementing the three-week research project, students had multiple opportunities to practice building requisite skills via 55 lessons focusing on the nature of science, scientific practices, technology, Common Core State Standards of reading, writing, listening and speaking, and Next Generation Science Standards. Project G.R.O.W. culminated with student generated research papers and oral presentations. Outcomes reveal students struggle with constructing explanations and the use of Excel to create meaningful graphs. They showed gains in data organization, analysis, teamwork and aspects of the nature of science.

    2018-04-01

    Typically the use of the Rayleigh-Sommerfeld diffraction formula as a photon propagator is widely accepted due to the abundant experimental evidence that suggests that it works. However, a direct link between the propagation of the electromagnetic field in classical optics and the propagation of photons where the square of the probability amplitude describes the transverse probability of the photon detection is still an issue to be clarified. We develop a mathematical formulation for the photon propagation using the formalism of electromagnetic field quantization and the path-integral method, whose main feature is its similarity with a fractional Fourier transform (FRFT). Here we show that because of the close relation existing between the FRFT and the Fresnel diffraction integral, this propagator can be written as a Fresnel diffraction, which brings forward a discussion of the fundamental character of it at the photon level compared to the Huygens-Fresnel principle. Finally, we carry out an experiment of photon counting by a rectangular slit supporting the result that the diffraction phenomenon in the Fresnel approximation behaves as the actual classical limit.

    This paper reports the results of an exploratory study that investigated the influence of technical uncertainty on the use of information and information sources by U.S. industry-affiliated aerospace engineers and scientists in completing or solving a project, task, or problem. Data were collected through a self-administered questionnaire. Survey participants were U.S. aerospace engineers and scientists whose names appeared on the Society of Automotive Engineers (SAE) mailing list. The results support the findings of previous research and the following study assumptions. Information and information-source use differ for projects, problems, and tasks with high and low technical uncertainty. As technical uncertainty increases, information-source use changes from internal to external and from informal to formal sources. As technical uncertainty increases, so too does the use of federally funded aerospace research and development (R&D). The use of formal information sources to learn about federally funded aerospace R&D differs for projects, problems, and tasks with high and low technical uncertainty.

    The Science Writer-at-Sea program is one small step in a marathon need for improved coverage of science and environmental issues. It targets two significant links in the Earth science communication pipeline: marine scientists and journalists; and attempts to reconnect people with the Earth by boosting their understanding of Earth science and its relevance to society. How it works: Journalism graduate students are invited to participate in oceanographic expeditions affiliated with InterRidge, an international organization dedicated to promoting ocean ridge research. InterRidge's outreach coordinator and science writer prepares each student for the expedition experience using materials she developed based on years of at-sea reporting. The students work side-by-side with the science writer and the scientists to research and write innovative journalistic stories for a general audience that are featured on a uniquely designed multimedia website that includes videos and images. The science, journalism and public communities benefit from this cost-effective program: science research is effectively showcased, scientists benefit from interactions with journalists, science outreach objectives are accomplished; student journalists enjoy a unique hands-on, `boot camp' experience; and the website enhances public understanding of `real' Earth science reported `on scene at sea.' InterRidge completed its first pilot test of the program in August 2005 aboard a Norwegian research cruise. A student writer entering the science journalism program at Columbia University participated. The results exceeded expectations. The team discovered the world's northernmost vent fields on the cruise, which expanded the original scope of the website to include a section specifically designed for the international press. The student was inspired by the cruise, amazed at how much she learned, and said she entered graduate school with much more confidence than she had prior to the program. The site

  2. On the Huygens principle for bianisotropic mediums with symmetric permittivity and permeability dyadics

    Mathematical statements of the Huygens principle relate the electric and magnetic field phasors at an arbitrary location in a source-free region enclosed by a surface to the tangential components of the electric and magnetic field phasors over that surface, via the dyadic Green functions applicable to the linear homogeneous medium occupying that region. We have mathematically formulated the Huygens principle for the electric and magnetic field phasors when the permittivity and permeability dyadics of the medium are symmetric, the symmetric parts of the two magnetoelectric dyadics of the medium are negative of each other, and both magnetoelectric dyadics also contain anti-symmetric terms. We have also formulated the Huygens principle for the electric (resp. magnetic) field phasor in a medium whose permittivity (resp. permeability) is scalar, the permeability (resp. permittivity) is symmetric, the symmetric parts of the two magnetoelectric dyadics reduce to dissimilar scalars, and anti-symmetric parts of the two magnetoelectric dyadics are identical. - Highlights: • The Huygens principle was formulated for bianistropic mediums when the permittivity and permeability dyadics of the medium are symmetric. • The formulation covers isotropic, biisotropic, and gyrotropic-like uniaxial mediums for which the Huygens principle is already available. • The formulation also covers new mediums like biaxial, chiro-omega, pseudo chiral, gyrotropic-like biaxial, and Lorentz reciprocal mediums.

  3. Comparative decline in funding of European Commission malaria vaccine projects: what next for the European scientists working in this field?

    Full Text Available Abstract Since 2000, under the Fifth and subsequent Framework Programmes, the European Commission has funded research to spur the development of a malaria vaccine. This funding has contributed to the promotion of an integrated infrastructure consisting of European basic, applied and clinical scientists in academia and small and medium enterprises, together with partners in Africa. Research has added basic understanding of what is required of a malaria vaccine, allowing selected candidates to be prioritized and some to be moved forward into clinical trials. To end the health burden of malaria, and its economic and social impact on development, the international community has now essentially committed itself to the eventual eradication of malaria. Given the current tentative advances towards elimination or eradication of malaria in many endemic areas, malaria vaccines constitute an additional and almost certainly essential component of any strategic plan to interrupt transmission of malaria. However, funding for malaria vaccines has been substantially reduced in the Seventh Framework Programme compared with earlier Framework Programmes, and without further support the gains made by earlier European investment will be lost.

  4. Project Roadkill: Linking European Hare vehicle collisions with landscape-structure using datasets from citizen scientists and professionals

    Road networks can implicate lots of negative effects for wildlife. One of the most important indication for strong landscape fragmentation are roadkills, i.e. collisions between motorised vehicles and wild animals. A species that is often involved in roadkills is the European hare (Lepus europaeus). European hare populations are in decline throughout Europe since the 1960s and classified as "potentially endangered" in the Red Data Book of Austria. Therefore, it is striking that in the hunting year 2013/14, 19,343 hares were killed on Austrian roads translating to 53 hare roadkills each day, or rather about two per hour. We hypothesized, that (I) hare-vehicle-collisions occur as an aggregation of events (hotspot), (II) the surrounding landscape influences the number of roadkilled hares and (III) roadkill data from citizen science projects and data from professionals (e.g. hunters, police) are convergent. Investigations on the surrounding landscape of the scenes of accidents will be carried out using land cover data derived from Landsat satellite images. Information on road kills are based on datasets from two different sources. One dataset stems from the citizen science project "Roadkill" (www.citizen-science.at/roadkill) where participants report roadkill findings via a web application. The second dataset is from a project where roadkill data were collected by the police and by hunters. Besides answering our research questions, findings of this project also allow the location of dangerous roadkill hotspots for animals and could be implemented in nature conservation actions.

    The development of the Chaîne des Puys and Limagne Fault World Heritage UNESCO project has taken about five years, since the Laboratoire Magmas et Volcans was approached by the local Auvergne government. Before this we had been working locally with organisations such as the Lemptégy volcano and Vulcania to help disseminate geoscience ideas to the general public, however the UNESCO project has lead us to do much more outreach. It has also stimulated our research and has taught us to better explain this to the lay person. In visiting other heritage projects, where we have exchanged ideas and best practice, we have been able to help other sites and improve what we do. These links are particularly important, as they can be used to help broaden the outlook of the general public and local actors, and increase further earth science literacy. I have noticed a strong increase in the awareness of the volcanoes, and volcanism as a result of the Chaîne des Puys and Limagne Fault project. I think that, before, many locals considered the volcanoes only as their special back garden, for easy walks and views and leisure, or for that matter farming, mining and hunting. However, now, there is a greater sense of pride rooted in the increased awareness of their geological significance in a historical and global context. While this effect is clear for the volcanoes, it is not yet apparent for the fault. The lay person has no clear concept of a rift and a fault. Thus, one of our major present challenges is to open the public's eyes to the fault. This is vital for the UNESCO project not only for educational reasons, but also because the fault scarp is a natural barrier that protects the rest of the property from urban development. Only if there is awareness of its nature and significance will it be an effective defence. To arrive at this goal, there is now a local government sponsored project to create and disseminate fault walks, fault viewpoints and fault information points. This is

    VeTOOLS is a project funded by the European Commission's Humanitarian Aid and Civil Protection department (ECHO), and aims at creating an integrated software platform specially designed to assess and manage volcanic risk. The project facilitates interaction and cooperation between scientists and Civil Protection Agencies in order to share, unify, and exchange procedures, methodologies and technologies to effectively reduce the impacts of volcanic disasters. The project aims at 1) improving and developing volcanic risk assessment and management capacities in active volcanic regions; 2) developing universal methodologies, scenario definitions, response strategies and alert protocols to cope with the full range of volcanic threats; 4) improving quantitative methods and tools for vulnerability and risk assessment; and 5) defining thresholds and protocols for civil protection. With these objectives, the VeTOOLS project points to two of the Sendai Framework resolutions for implementing it: i) Provide guidance on methodologies and standards for risk assessments, disaster risk modelling and the use of data; ii) Promote and support the availability and application of science and technology to decision-making, and offers a good example on how a close collaboration between science and civil protection is an effective way to contribute to DRR.

    We prove that rational solutions of the AKNS hierarchy of the form q=σ/τ and r=ρ/τ, where (σ,τ,ρ) are certain Schur functions, naturally yield Dirac operators of strict Huygens' type, i.e., the support of their fundamental solutions is the surface of the light-cone. This strengthens the connection between the theory of completely integrable systems and Huygens' principle by extending to the Dirac operators and the rational solutions of the AKNS hierarchy a classical result of Lagnese and Stellmacher concerning perturbations of wave operators

    Results are reported from pilot surveys on the use of scientific and technical information (STI) by U.S. and NATO-nation aerospace scientists and engineers, undertaken as part of the NASA/DOD Aerospace Knowledge Diffusion Research Project. The survey procedures and the demographic characteristics of the 67 scientists and engineers who responded to the survey are summarized, and the results are presented in a series of tables and discussed in detail. Findings emphasized include: (1) both U.S. and NATO respondents spend around 60 percent of their work week producing or using STI products; (2) NATO respondents are more likely than their U.S. counterparts to use 'formal' STI products (like technical reports and papers) and the services of librarians and online data bases; (3) most of the respondents use computers and information technology in preparing STI products; and (4) respondents who had taken courses in technical communication agreed on the value and ideal subject matter of such courses.

    The project examines how the results of NASA/DOD research diffuse into the aerospace R&D process, and empirically analyzes the implications of the aerospace knowledge diffusion process. Specific issues considered are the roles played by government technical reports, the recognition of the value of scientific and technical information (STI), and the optimization of the STI aerospace transfer system. Information-seeking habits are assessed for the U.S. aerospace community, the general community, the academic sector, and the international community. U.S. aerospace engineers and scientists use 65 percent of working time to communicate STI, and prefer 'internal' STI over 'external' STI. The isolation from 'external' information is found to be detrimental to U.S. aerospace R&D in general.

  10. Model program for the recruitment and preparation of high ability elementary mathematics/science teachers: A collaborative project among scientists, teacher educators and classroom teachers

    Energy Technology Data Exchange (ETDEWEB)

    1993-12-01

    This teacher education program will provide a model for recruiting, educating and retaining high ability students to become mathematics and science lead teachers in elementary schools. The quality experiences and support provided these students will help them develop the knowledge and attitudes necessary to provide leadership for elementary mathematics and science programs. Students will have research experiences at the Ames Laboratory, high quality field experiences with nationally recognized mathematics and science teachers in local schools and opportunities to meaningfully connect these two experiences. This program, collaboratively designed and implemented by scientists, teacher educators and classroom teachers, should provide a replicatable model for other teacher education institutions. In addition, materials developed for the project should help other laboratories interface more effectively with K-8 schools and help other teacher education programs incorporate real science and mathematics experience into their curriculum.

    Titan is one of the primary scientific objectives of the NASA-ESA-ASI Cassini-Huygens mission. Scattering by haze particles in Titan's atmosphere and numerous methane absorptions dramatically veil Titan's surface in the visible range, though it can be studied more easily in some narrow infrared windows. The Visual and Infrared Mapping Spectrometer (VIMS) instrument onboard the Cassini spacecraft successfully imaged its surface in the atmospheric windows, taking hyperspectral images in the range 0.4-5.2 ??m. On 26 October (TA flyby) and 13 December 2004 (TB flyby), the Cassini-Huygens mission flew over Titan at an altitude lower than 1200 km at closest approach. We report here on the analysis of VIMS images of the Huygens landing site acquired at TA and TB, with a spatial resolution ranging from 16 to14.4 km/pixel. The pure atmospheric backscattering component is corrected by using both an empirical method and a first-order theoretical model. Both approaches provide consistent results. After the removal of scattering, ratio images reveal subtle surface heterogeneities. A particularly contrasted structure appears in ratio images involving the 1.59 and 2.03 ??m images north of the Huygens landing site. Although pure water ice cannot be the only component exposed at Titan's surface, this area is consistent with a local enrichment in exposed water ice and seems to be consistent with DISR/Huygens images and spectra interpretations. The images show also a morphological structure that can be interpreted as a 150 km diameter impact crater with a central peak. ?? 2006 Elsevier Ltd. All rights reserved.

    During the Winter College on Nuclear Physics and Reactors jointly organized by the IAEA and the International Centre for Theoretical Physics (ICTP) in January - March 1980 and held at the ICTP in Trieste, a Working Group was convened from participants in the Interregional Advanced Training Course on Applications of Nuclear Theory to Nuclear Data Calculations for Reactor Design. The Working Group examined the current fast neutron nuclear data requirements for nuclear technologies and discussed possible means to meet these requirements, with a major emphasis on the possible contributions by and benefit for the developing countries. The Working Group concluded that the organisation of an IAEA-sponsored Project of Interregional Co-operation for Training of Nuclear Scientists in Developing Countries, Using the Expertise Available in the Nuclear Data Field, would be the best solution to cope with the problems in question and drafted an outline of the technical programme and organization of such a project the revised version of which is presented in this report

    A telephone survey of U.S. aerospace engineers and scientists belonging to the Society of Automotive Engineers (SAE) was conducted between December 4, 1991 and January 5, 1992. The survey was undertaken to (1) validate the telephone survey as an appropriate technique for collecting data from U.S. aerospace engineers and scientists; (2) collect information about how the results of NASA/DoD aerospace research are used in the R&D process; (3) identify those selection criteria which affect the use of federally-funded aerospace R&D; and (4) obtain information that could be used to develop a self-administered mail questionnaire for use with the same population. The average rating of importance of U.S. government technical reports was 2.5 (on a 4-point scale); The mean/median number of times U.S. government technical reports were used per 6 months was 8/2. Factors scoring highest for U.S. government technical reports were technical accuracy (2.9), reliable data and technical information (2.8), and contains comprehensive data and information (2.7) on a 4-point system. The factors scoring highest for influencing the use of U.S. government technical reports were relevance (3.1), technical accuracy (3.06), and reliable data/information (3.02). Ease of use, familiarity, technical accuracy, and relevance correlated with use of U.S. government technical reports. Survey demographics, survey questionnaire, and the NASA/DoD Aerospace Knowledge Diffusion Research Project publications list are included.

    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

    We developed a series of balloon experiments parachuting a 1:1 scale mock-up of the Huygens probe from an altitude just over 30 km to simulate at planetary scale the final part of the descent of the probe through Titan's lower atmosphere. The terrestrial atmosphere represents a natural laboratory where most of the physical parameters meet quite well the bulk condition of Titan's environment, in terms of atmosphere composition, pressure and mean density ranges, though the temperature range will be far higher. The probe mock-up consists of spares of the HASI sensor packages, housekeeping sensors and other dedicated sensors, and also incorporates the Huygens Surface Science Package (SSP) Tilt sensor and a modified version of the Beagle 2 UV sensor, for a total of 77 acquired sensor channels, sampled during ascent, drift and descent phase. An integrated data acquisition and instrument control system, simulating the HASI data-processing unit (DPU), has been developed, based on PC architecture and soft-real-time application. Sensor channels were sampled at the nominal HASI data rates, with a maximum rate of 1 kHz. Software has been developed for data acquisition, onboard storage and telemetry transmission satisfying all requests for real-time monitoring, diagnostic and redundancy. The mock-up of the Huygens probe mission was successfully launched for the second time (first launch in summer 2001, see Gaborit et al., 2001) with a stratospheric balloon from the Italian Space Agency Base "Luigi Broglio" in Sicily on May 30, 2002, and recovered with all sensors still operational. The probe was lifted to an altitude of 32 km and released to perform a parachuted descent lasting 53 min, to simulate the Huygens mission at Titan. Preliminary aerodynamic study of the probe has focused upon the achievement of a descent velocity profile reproducing the expected profile of Huygens probe descent into Titan. We present here the results of this experiment discussing their relevance in

Livros didáticos lhe rendem homenagens atribuindo seu nome a um princípio, mas em sua obra máxima, Tratado sobre a luz, é possível se ver muito mais: sua inventividade na defesa de um modelo ondulatório para a luz como alternativo ao modelo corpuscular. Neste trabalho, tenta-se evidenciar o raciocínio de Huygens, mostrando que, apesar de ter sido publicada há mais de trezentos anos, a obra está escrita numa linguagem relativamente acessível.

  5. Janus and Huygens Dipoles: Near-Field Directionality Beyond Spin-Momentum Locking

    Unidirectional scattering from circularly polarized dipoles has been demonstrated in near-field optics, where the quantum spin-Hall effect of light translates into spin-momentum locking. By considering the whole electromagnetic field, instead of its spin component alone, near-field directionality can be achieved beyond spin-momentum locking. This unveils the existence of the Janus dipole, with side-dependent topologically protected coupling to waveguides, and reveals the near-field directionality of Huygens dipoles, generalizing Kerker's condition. Circular dipoles, together with Huygens and Janus sources, form the complete set of all possible directional dipolar sources in the far- and near-field. This allows the designing of directional emission, scattering, and waveguiding, fundamental for quantum optical technology, integrated nanophotonics, and new metasurface designs.

    In this article, Russian bomb designers answer the KGB's claim that espionage, not science, produced the Soviet bomb. Yuli Khariton and Yuri Smirnov wholly reject the argument that Soviet scientists can claim little credit for the first Soviet bomb. In a lecture delivered at the Kurchatov Institute, established in 1943 when Igor Kurchatov became the director of the Soviet nuclear weapons project, Khariton and Smironov point to the work done by Soviet nuclear physicists before 1941 and refute assertions that have been made in Western literature regarding the hydrogen bomb

  7. Theory, design, and experimental verification of a reflectionless bianisotropic Huygens' metasurface for wide-angle refraction

    Huygens' metasurfaces are electrically thin devices which allow arbitrary field transformations. Beam refraction is among the first demonstrations of realized metasurfaces. As previously shown for extreme-angle refraction, control over only the electric impedance and magnetic admittance of the Huygens' metasurface proved insufficient to produce the desired reflectionless field transformation. To maintain zero reflections for wide refraction angles, magnetoelectric coupling between the electric and magnetic response of the metasurface, leading to bianisotropy, can be introduced. In this paper, we report the theory, design, and experimental characterization of a reflectionless bianisotropic metasurface for extreme-angle refraction of a normally incident plane wave towards 71.8° at 20 GHz. The theory and design of three-layer asymmetric bianisotropic unit cells are discussed. The realized printed circuit board structure was tested via full-wave simulations as well as experimental characterization. To experimentally verify the prototype, two setups were used. A quasi-optical experiment was conducted to assess the specular reflections of the metasurface, while a far-field antenna measurement characterized its refraction nature. The measurements verify that the fabricated metasurface has negligible reflections and the majority of the scattered power is refracted to the desired Floquet mode. This provides an experimental demonstration of a reflectionless wide-angle refracting metasurface using a bianisotropic Huygens' metasurface at microwave frequencies.

  8. Scientific and synergistic lessons learned from the Cassini-Huygens mission

    Science.gov (United States)

    Coustenis, Athena

    The Cassini-Huygens mission to the Saturnian system has been an extraordinary success for the planetary community since the Saturn-Orbit-Insertion (SOI) in July 2004 and again the very successful probe descent and landing of Huygens on January 14, 2005. One of its main targets was Titan. Titan, Saturn's largest satellite, is the only other object in our Solar system to possess an extensive nitrogen atmosphere, host to an active organic chemistry, based on the interaction of N2 with methane (CH4). Titan was revealed to be a complex world more like the Earth than any other: it has a dense mostly nitrogen atmosphere and active climate and meteorological cycles where the working fluid, methane, behaves under Titan conditions the way that water does on Earth. Its geology, from lakes and seas to broad river valleys and mountains, while carved in ice is, in its balance of processes, again most like Earth. Beneath this panoply of Earth-like processes an ice crust floats atop what appears to be a liquid water ocean. Titan is also rich in organic molecules—more so in its surface and atmosphere than anyplace in the solar system, including Earth [2-4]. These molecules were formed in the atmosphere, deposited on the surface and, in coming into contact with liquid water may undergo an aqueous chemistry that could replicate aspects of life's origins. I will discuss our current understanding of Titan's complex environment in view of the Cassini-Huygens mission results [1-8], which demonstrated the power of synergistic remote and in situ exploration. I will focus on the atmospheric structure (temperature and composition), and the surface nature. I will show how these and other elements can give us clues as to the origin and evolution of the satellite, and how they connect to the observations of the other satellites, Enceladus in particular. Future space missions to Titan can help us understand the kronian and also our Solar System as a whole. Finally, I will describe the future

    Titan is an icy satellite of Saturn with a dense atmosphere and covered by a global photochemical organic haze. Ground based observations and the Huygens descent probe allowed to retrieve the main spectral signature of the water ice (Griffith, C.A. et al. [2003]. Science 300(5619), 628-630; Coustenis, A. et al. [2005]. Icarus 177, 89-105) at the surface, possibly covered by a layer of sedimented organic material (Tomasko, M.G. et al. [2005]. Nature 438(7069), 765-778). However, the spectrum of the surface is not yet understood. In this study, we find that the surface reflectivity at the Huygens Landing Site (HLS) is well modeled by a layer of water ice grains overlaid by a moist layer of weakly compacted photochemical aggregated aerosols. Moist soils have spectra shifted toward short wavelengths relatively to spectra of dry soils. Cassini observations of Shangri-La region from orbit also show a very dark surface with a reflectivity peak shifted toward short wavelengths in respect to the reflectivity peak of bright surfaces, revealing a dichotomy between terrains based to their spectra in visible.

    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.

  14. 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

    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.

    To understand the diffusion of aerospace knowledge, it is necessary to understand the communications practices and the information-seeking behaviors of those involved in the production, transfer, and use of aerospace knowledge at the individual, organizational, national, and international levels. In this paper, we report selected results from a survey of Japanese and U.S. aerospace engineers and scientists that focused on communications practices and information-seeking behaviors in the workplace. Data are presented for the following topics: importance of and time spent communicating information, collaborative writing, need for an undergraduate course in technical communications, use of libraries, the use and importance of electronic (computer) networks, and the use and importance of foreign and domestically produced technical reports. The responses of the survey respondents are placed within the context of the Japanese culture. We assume that differences in Japanese and U.S. cultures influence the communications practices and information-seeking behaviors of Japanese and U.S. aerospace engineers and scientists.

    The Huygens probe, which will study the clouds, atmosphere and surface of Saturn's largest moon, Titan, as part of the Cassini mission to Saturn, is prepared for transport from the Skid Strip, Cape Canaveral Air Station (CCAS), after being off-loaded from a plane. The probe was designed and developed for the European Space Agency (ESA) by a European industrial consortium led by Aerospatiale as prime contractor. Over the past year, it was integrated and tested at the facilities of Daimler Benz Aerospace Dornier Satellitensysteme in Germany. The probe will be mated to the Cassini orbiter, which was designed and assembled at NASA's Jet Propulsion Laboratory in California. The Cassini launch is targeted for October 6 from CCAS aboard a Titan IVB/Centaur expendable launch vehicle. After arrival at Saturn in 2004, the probe will be released from the Cassini orbiter to slowly descend through the Titan atmosphere to the moon's surface.

    In this paper we describe the practical realization and the analysis of a thought experiment devised by Christiaan Huygens, which was pivotal in his derivation of the formula for the radius of gyration of a compound pendulum. Measurements are realized by recording the experiment with a digital camera, and using a video analysis and modelling software tool to process and extract information from the acquired videos. Using this setup, detailed quantitative comparisons between measurements and theoretical predictions can be carried out, focusing on many relevant topics in the undergraduate physics curriculum, such as the ‘radius of gyration’, conservation of energy, moment of inertia, constraint and reaction forces, and the behaviour of the centre of mass.

    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.

    How do you get middle and high school students excited about scientific inquiry? Have them join a collaborative research team in Antarctica! A comprehensive education program brought ocean science, marine ecology, and climate change impact research to more than 950 students in 2014-15 to increase their exposure to and excitement of current research. The program was integrated into a collaborative research project, involving five universities, that worked to characterize the connection between ocean circulation, plankton distribution, penguin foraging behavior, and climate change around Palmer Station, Antarctica. The scientists and education team co-led a weeklong workshop to expose 22 teachers to the research science, build relationships among the teachers and scientists, and refine the program to most effectively communicate the research to their students. In the fall, teachers taught NGSS-aligned, hands-on, data-focused classroom lessons to provide their students the necessary content to understand the project hypotheses using multiple science practices. Through a professional science blog and live video calls from Antarctica, students followed and discussed the science teams work while they were in the field. To apply the science practices the students had learned about, they designed, conducted, and analyzed their own ocean-related, inquiry-based research investigation as the culminating component of the program (results were presented at a Student Research Symposium attended by the science team). Of their own choosing, roughly half of the students used raw data from the CONVERGE research (including krill, CODAR, penguin, and glider data) for their investigations. This presentation will focus on the evaluation results of the education program to identify the aspects that successfully engaged teachers and students with scientific inquiry, science practices, and authentic data as well as the replicability of this integrated scientist-teacher partnership and

    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.

    Current reforms in science education place increasing demands on teachers and students to engage not only with scientific content but also to develop an understanding of the nature of scientific inquiry (AAAS, 1993; NRC, 1996). Teachers are expected to engage students with authentic scientific practices including posing questions, conducting observations, analyzing data, developing explanations and arguing about them using evidence. This charge is challenging for many reasons most notably the difficulty in obtaining meaningful data about complex scientific phenomena that can be used to address relevant scientific questions that are interesting and understandable to K-12 students. We believe that ocean sciences provide an excellent context for fostering scientific inquiry in the classroom. Of particular interest are the technological and scientific advances of Ocean Observing Systems, which allow scientists to continuously interact with instruments, facilities, and other scientists to explore the earth-ocean- atmosphere system remotely. Oceanographers are making long-term measurements that can also resolve episodic oceanic processes on a wide range of spatial and temporal scales crucial to resolving scientific questions related to Earth's climate, geodynamics, and marine ecosystems. The availability of a diverse array of large data sets that are easily accessible provides a unique opportunity to develop inquiry-based learning environments in which students can explore many important questions that reflect current research trends in ocean sciences. In addition, due to the interdisciplinary nature of the ocean sciences these data sets can be used to examine ocean phenomena from a chemical, physical, or biological perspective; making them particularly useful for science teaching across the disciplines. In this session we will describe some of the efforts of the Centers for Ocean Sciences Education Excellence- Mid Atlantic (COSEE MA) to develop instructional materials

    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

    Full text: Many objects in Nature - elementary particles, nuclei, atoms, molecules, DNA, proteins, etc. are build as self-consistent hierarchical systems and have the same homological construction in the sense that they are found by the same fundamental physical laws: energy-momentum conservation law and sectoral conservation law (the second Kepler law). Schroedinger wrote that an interaction between microscopic physical objects is controlled by specific resonance laws. According to these laws any interaction in a microscopic hierarchic wave system exhibits the resonance character. Due to above said the corresponding partial motion are determinate. This determinism arises as a consequences of the energy conservation law. As the resonance condition arises from the fundamental energy conservation law, the rhythms and synchronization of the majority of phenomena to be observed are the reflection of the universal property of self-organization of the Universe. The Huygens synchronization principle is substantiated at the microscopic level as the consequence of energy conservation law and resonance character of any interaction between wave systems. In this paper we demonstrated the universality of the Huygens synchronization principle independent of substance, fields, and interactions for microsystems. Thereby, webbing some arguments in favor of the mechanism - ORDER from ORDER, declared by Schrodinger is fundamental problem of contemporary science. We came to conclusion that a stable proton and neutron play the role of standard for other elementary particles and nuclei. They contain all necessary information about structure of other particles and nuclei. This information is used and reproduced by simple rational relations, according to the fundamental conservation law of energy momentum. We originated from the principles of commensurability and self-similarity. The commensurability and self-similarity result in the very unity of the world. The principle of

    The bilateral project of Belarus and Germany was commissioned on 1.04.1993 and is placed under the scientific guidance of the Gemeinschaftsausschuss Strahlenforschung. In the framework of the project part devoted to ''therapy and medical training'', covering the period from 1.04.1993 until 31.03.1996, all in all 99 children from Belarus suffering from advanced-stage tumors of the thyroid received a special radio-iodine therapy in Germany. In about 60% of the children complete removal of the tumor was achieved. Another task of the project was to train over the reporting period 41 doctors and physicists from Belarus in the fields of nuclear medical diagnostic evaluation and therapy of thyroid tumors. The project part ''biological dosimetry'' was to investigate the role of micronuclei in peripheral lymphocytes, and whether their presence in the lymphocytes permits to derive information on the radiation dose received even several years after the reactor accident. The scientists also examained the role of the micronuclei in follow-up examinations of the radio-iodine therapy. Further studies used the relatively large number of tumors in the children, as compared to the literature available until the accident, to examine whether there are specific mutation patterns to be found in tumot suppressor genes (p-53) in thyroid tumors which might be used as indicators revealing radiation-induced onset of tumor growth. The project part ''retrospective dosimetry and risk analysis'' was in charge of detecting information answering the question of whether the release of I-131, suspected to be critical nuclide, really was the cause of enhanced incidence of thyroid tumors in the children. The project part ''coordination and examination center at Minsk'' was to establish and hold available the support required by the GAST project participants. (orig./CB) [de

  15. Scientists as writers

    Yore, Larry D.; Hand, Brian M.; Prain, Vaughan

    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

    Aerospace engineers and scientists from Western Europe, Japan, and the United States were surveyed as part of the NASA/DoD Aerospace Knowledge Diffusion Research Project. Questionnaires were used to solicit their opinions regarding the following: (1) the importance of technical communications to their profession; (2) the use and production of technical communications; and (3) their views about the appropriate content of an undergraduate course in technical communications. The ability to communicate technical information effectively was very important to the aerospace engineers and scientists who participated in the study. A considerable portion of their working week is devoted to using and producing technical information. The types of technical communications used and produced varied within and among the three groups. The type of technical communication product used and produced appears to be related to respondents' professional duties. Respondents from the three groups made similar recommendations regarding the principles, mechanics, and on-the-job communications to be included in an undergraduate technical communications course for aerospace majors.

    Objective. Characterize and understand acoustic instrument performance on the surface of Titan. Methods. The Huygens probe measured the speed of sound in Titan's atmosphere with a 1 MHz pulse time-of-flight transducer pair near the bottom of the vehicle. We examine the fraction of pulses correctly received as a function of time. Results. This system returned good data from about 11 km altitude, where the atmosphere became thick enough to effectively transmit the sound, down to the surface just before landing: these data have been analyzed previously. After an initial transient at landing, the instrument operated nominally for about 10 min, recording pulses much as during descent. The fraction of pulses detected then declined and the transmitted sound ceased to be detected altogether, despite no indication of instrument or probe configuration changes. Conclusions. The most likely explanation appears to be absorption of the signal by polyatomic gases with relaxation losses at the instrument frequency, such as ethane, acetylene and carbon dioxide. These vapors, detected independently by the GCMS instrument, were evolved from the surface material by the warmth leaking from the probe, and confirm the nature of the surface materials as 'damp' with a cocktail of volatile compounds. Some suggestions for future missions are considered. Practice implications. None.

  20. Extended Huygens-Fresnel principle and optical waves propagation in turbulence: discussion.

    Charnotskii, Mikhail

    2015-07-01

    Extended Huygens-Fresnel principle (EHF) currently is the most common technique used in theoretical studies of the optical propagation in turbulence. A recent review paper [J. Opt. Soc. Am. A31, 2038 (2014)JOAOD60740-323210.1364/JOSAA.31.002038] cites several dozens of papers that are exclusively based on the EHF principle. We revisit the foundations of the EHF, and show that it is burdened by very restrictive assumptions that make it valid only under weak scintillation conditions. We compare the EHF to the less-restrictive Markov approximation and show that both theories deliver identical results for the second moment of the field, rendering the EHF essentially worthless. For the fourth moment of the field, the EHF principle is accurate under weak scintillation conditions, but is known to provide erroneous results for strong scintillation conditions. In addition, since the EHF does not obey the energy conservation principle, its results cannot be accurate for scintillations of partially coherent beam waves.

  1. Marketing for scientists

    2012-01-01

    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...

Many investigations were neutral,others aimed at peaceful and beneficial use for humanity, a few were made for destructive purposes. Researchers have no or very little influence on the application of their results. The interplay between natural scientists ,social scientists,politicians,and their dependence on economic factors will be discussed.

  3. Strategic Institutional Change to Support Advancement of Women Scientists in the Academy: Lessons from a Study of ADVANCE-IT Projects

    2011-12-01

    While women's representation among undergraduate and graduate degree-earners has grown steadily in most science fields, progress at the faculty level has been slow to realize, especially in upper academic ranks and in higher status institutions. This is only partly explained by the slow turnover of faculty positions. While some efforts to address this issue have aimed to support individual women and foster their career success, the National Science Foundation's ADVANCE program has taken a different approach, calling for institutions to take a systemic and organizational approach to enhance women's representation in the academy. Since 2001, some 50 institutions have received ADVANCE Institutional Transformation (IT) awards to develop such systemic approaches. Most ADVANCE-IT projects have attended to structures (e.g. committee and departmental leadership roles), processes (e.g. hiring), policy (e.g. family leave), attitudes and awareness (e.g. training for chairs), and workplace climate, as well as interventions that focus on faculty members as valuable human resources. Our research team is studying ADVANCE institutions' approaches to organizational change, by identifying and categorizing individual change interventions, examining how they combine to build an overall change portfolio, and considering how change interventions are selected or adapted to fit a specific institutional context. Because universities are complex organizations composed of multiple, loosely coupled, interconnected sub-systems, an overall change strategy cannot depend on a single type of intervention. Yet any particular intervention might be deployed on behalf of multiple goals and in a variety of forms that may depend on the context, or institutional system, in which it is introduced. We will discuss some common types of strategic intervention used in ADVANCE-IT projects, categorized by Bolman and Deal's (1991) four main perspectives or "lenses" for understanding organizational issues.

    The Huygen's probe of the atmosphere of Saturn's moon Titan includes one optical instrument sensitive to the wavelengths of solar radiation. The goals of this investigation fall into four broad areas: 1) the measurement of the profile of solar heating to support an improved understanding of the thermal balance of Titan and the role of the greenhouse effect in maintaining Titan's temperature structure; 2) the measurement of the size, vertical distribution, and optical properties of the aerosol and cloud particles in Titan's atmosphere to support studies of the origin, chemistry, life cycles, and role in the radiation balance of Titan played by these particles; 3) the composition of the atmosphere, particularly the vertical profile of the mixing ratio of methane, a condensable constituent in Titan's atmosphere; and 4) the physical state, composition, topography, and physical processes at work in determining the nature of the surface of Titan and its interaction with Titan's atmosphere. In order to accomplish these objectives, the Descent Imager/Spectral Radiometer (DISR) instrument makes extensive use of fiber optics to bring the light from several different sets of foreoptics to a silicon CCD detector, to a pair of InGaAs linear array detectors, and to three silicon photometers. Together these detectors permit DISR to make panoramic images of the clouds and surface of Titan, to measure the spectrum of upward and downward streaming sunlight from 350 to 1700 nm at a resolving power of about 200, to measure the reflection spectrum of >= 3000 locations on the surface, to measure the brightness and polarization of the solar aureole between 4 and 30 degrees from the sun at 500 and 935 nm, to separate the direct and diffuse downward solar flux at each wavelength measured, and to measure the continuous reflection spectrum of the ground between 850 and 1600 nm using an onboard lamp in the last 100 m of the descent.

    Telling stories is a cliché for best practice in science videos. It's upheld as a method to capture audience attention in many fields. Findings from neurobiology research show character-driven stories cause the release of the neurochemical oxytocin in the brain. Oxytocin motivates cooperation with others and enhances a sense of empathy, in particular the ability to experience others' emotions. Developing character tension- as in our video design showcasing scientists along with their work- holds the viewers' attention, promotes recall of story, and has the potential to clearly broadcast the feelings and behaviors of the scientists. The brain chemical change should help answer the questions: Why should a viewer care about this science? How does it improve the world, or our lives? Is just a story-driven video the solution to science outreach? Answer: Not in our multi-media world. Frontier Scientists (FS) discovered in its three year National Science Foundation project titled 'Science in Alaska: using Multimedia to Support Science Education': the storied video is only part of the effort. Although FS created from scratch and drove a multimedia national campaign throughout the project, major reach was not achieved. Despite FS' dedicated web site, YouTube channel, weekly blog, monthly press release, Facebook and G+ pages, Twitter activity, contact with scientists' institutions, and TV broadcast, monthly activity on the web site seemed to plateau at about 3000 visitors to the FS website per month. Several factors hampered the effort: Inadequate funding for social media limited the ability of FS to get the word to untapped markets: those whose interest might be sparked by ad campaigns but who do not actively explore unfamiliar agencies' science education content. However, when institutions took advantage of promoting their scientists through the FS videos we saw an uptick in video views and the participating scientists were often contacted for additional stories or were

    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.

    In 2005, the complex permittivity of the surface of Saturn's moon Titan was measured by the PWA-MIP/HASI (Permittivity Wave Altimetry-Mutual Impedance Probe/Huygens Atmospheric Structure Instrument) experiment on board the Huygens probe. The analysis of these measurements was recently refined but could not be interpreted in terms of composition due to the lack of knowledge on the low-frequency/low-temperature electrical properties of Titan's organic material, a likely key ingredient of the surface composition. In order to fill that gap, we developed a dedicated measurement bench and investigated the complex permittivity of analogs of Titan's organic aerosols called "tholins." These laboratory measurements, together with those performed in the microwave domain, are then used to derive constraints on the composition of Titan's first meter below the surface based on both the PWA-MIP/HASI and the Cassini Radar observations. Assuming a ternary mixture of water ice, tholin-like dust and pores (filled or not with liquid methane), we find that at least 10% of water ice and 15% of porosity are required to explain observations. On the other hand, there should be at most 50-60% of organic dust. PWA-MIP/HASI measurements also suggest the presence of a thin conductive superficial layer at the Huygens landing site. Using accurate numerical simulations, we put constraints on the electrical conductivity of this layer as a function of its thickness (e.g., in the range 7-40 nS/m for a 7-mm thick layer). Potential candidates for the composition of this layer are discussed.

    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)

    The U.S. government technical report is a primary means by which the results of federally funded research and development (R&D) are transferred to the U.S. aerospace industry. However, little is known about this information product in terms of its actual use, importance, and value in the transfer of federally funded R&D. To help establish a body of knowledge, the U.S. government technical report is being investigated as part of the NASA/DOD Aerospace Knowledge Diffusion Research Project. In this report, we summarize the literature on technical reports and provide a model that depicts the transfer of federally funded aerospace R&D via the U.S. government technical report. We present results from our investigation of aerospace knowledge diffusion vis-a-vis the U.S. government technical report, and present the results of research that investigated aerospace knowledge diffusion vis-a-vis the technical communications practices of U.S. aerospace engineers and scientists who were assigned to the Research and Technology Group (RTG) at the NASA Langley Research Center in September 1995.

  20. 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)

    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.

  5. Huygens triviality of the time-independent Schrödinger equation. Applications to atomic and high energy physics

    Kholodenko, Arkady L.; Kauffman, Louis H.

    2018-03-01

    Huygens triviality - a concept invented by Jacques Hadamard - describes an equivalence class connecting those 2nd order partial differential equations which are transformable into the wave equation. In this work it is demonstrated, that the Schrödinger equation with the time-independent Hamiltonian belongs to such an equivalence class. The wave equation is the equation for which Huygens' principle (HP) holds. The HP was a subject of confusion in both physics and mathematics literature for a long time. Not surprisingly, the role of this principle was obscured from the beginnings of quantum mechanics causing some theoretical and experimental misunderstandings. The purpose of this work is to bring the full clarity into this topic. By doing so, we obtained a large amount of new results related to uses of Lie sphere geometry, of twistors, of Dupin cyclides, of null electromagnetic fields, of AdS-CFT correspondence, of Penrose limits, of geometric algebra, etc. in physical problems ranging from the atomic to high energy physics and cosmology.

    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.

  11. Python for scientists

    Stewart, John M

    2017-01-01

    Scientific Python is a significant public domain alternative to expensive proprietary software packages. This book teaches from scratch everything the working scientist needs to know using copious, downloadable, useful and adaptable code snippets. Readers will discover how easy it is to implement and test non-trivial mathematical algorithms and will be guided through the many freely available add-on modules. A range of examples, relevant to many different fields, illustrate the language's capabilities. The author also shows how to use pre-existing legacy code (usually in Fortran77) within the Python environment, thus avoiding the need to master the original code. In this new edition, several chapters have been re-written to reflect the IPython notebook style. With an extended index, an entirely new chapter discussing SymPy and a substantial increase in the number of code snippets, researchers and research students will be able to quickly acquire all the skills needed for using Python effectively.

    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.

    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

  18. 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.

    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

    1991-01-01

    In this paper, the diffusion of federally funded aerospace R&D is explored from the perspective of the information-seeking behavior of U.S. aerospace engineers and scientists. The following three assumptions frame this exploration: (1) knowledge production, transfer, and utilization are equally important components of the aerospace R&D process; (2) the diffusion of knowledge resulting from federally funded aerospace R&D is indispensable for the U.S. to remain a world leader in aerospace; and (3) U.S. government technical reports, produced by NASA and DOD, play an important, but as yet undefined, role in the diffusion of federally funded aerospace R&D. A conceptual model for federally funded aerospace knowledge diffusion, one that emphasizes U.S. goverment technical reports, is presented. Data regarding three research questions concerning the information-seeking behavior of U.S. aerospace engineers and scientists are also presented.

    A study was undertaken to investigate the relationship between the use of U.S. government technical reports by U.S. aerospace engineers and scientists and seven selected sociometric variables. Data were collected by means of a self-administered mail survey which was distributed to a randomly drawn sample of American Institute of Aeronautics and Astronautics (AIAA) members. Two research questions concerning the use of conference meeting papers, journal articles, in-house technical reports, and U.S. government technical reports were investigated. Relevance, technical quality, and accessibility were found to be more important determinants of the overall extent to which U.S. government technical reports and three other information products were used by U.S. aerospace engineers and scientists.

    This paper is based on the premise that scientific and technical information (STI), its use by aerospace engineers and scientists, and the aerospace research and development (R&D) process are related. We intend to support this premise with data gathered from numerous studies concerned with STI, the relationship of STI to the performance and management of R&D activities, and the information use and seeking behavior of engineers in general and aerospace engineers and scientists in particular. We intend to develop and present a synthesized appreciation of how aerospace R&D managers can improve the efficacy of the R&D process by understanding the role and value of STI in this process.

    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. This is a project devoted to demonstrate innovative ways to involve teachers and students in e-Science through the use of virtual labs, that

    1995-01-01

    Studies indicate that communications and information-related activities take up a substantial portion of an engineer's work week; therefore, effective communications and information-use skills are one of the key engineering competencies that early career-stage aerospace engineers and scientists must possess to be successful. Feedback from industry rates communications and information-use skills high in terms of their importance to engineering practice; however, this same feedback rates the communications and information-use skills of early career-stage engineers low. To gather adequate and generalizable data about the communications and information-related activities of entry-level aerospace engineers and scientists, we surveyed 264 members of the AIAA who have no more than 1-5 years of aerospace engineering work experience. To learn more about the concomitant communications norms, we compared the results of this study with data (1,673 responses) we collected from student members of the AIAA and with data (341 responses) we collected from a study of aerospace engineering professionals. In this paper, we report selected results from these studies that focused on the communications practices and information-related activities of early career-stage U.S. aerospace engineers and scientists in the workplace.

  7. Project first and eye on the sky: strategies for teaching space science in the early grades

    Science.gov (United States)

    Paglierani, R.; Hawkins, I.

    Elementary educators typically have only limited opportunity to teach substantive science units. This is due, in great part, to the current primary focus on literacy and mathematics instruction in the early grades. It is not surprising then, that the time and resources allocated to science teaching are significantly less than those allocated to language arts and mathematics. The integration of elementary science curricula with language arts provides one means of addressing the challenge of maintaining a robust science presence in the elementary classroom. Project FIRST's Eye on the Sky suggests a model for the successful integration of science instruction with language arts through inquiry-based learning. The model has been adopted by other Education/Public Outreach efforts, most recently, the Cassini- Huygens Mission and the Space Telescope Institute. We will present Eye on the Sky: Our Star the Sun, a suite of integrated, inquiry-based lessons designed specifically for K-4 students and discuss data showing the program's impact on the user audience. These materials offer an exciting opportunity to explore the dynamic Sun and share research discoveries of NASA's Sun-Earth Connection with the elementary education community. The lessons were developed and tested by UC Berkeley educators and NASA scientists in partnership with classroom teachers. We will review the program components and examine the benefits and challenges inherent in implementing such a program in the elementary school setting.

  8. Has ADVANCE Affected Senior Compared to Junior Women Scientists Differently?

    Science.gov (United States)

    Rosser, Sue

    2015-01-01

    Substantial evidence exists to demonstrate that the NSF ADVANCE Inititiative has made a positive impact upon institutions. Since it began in 2001, ADVANCE has changed the conversation, policies, and practices in ways to remove obstacles and systemic barriers preventing success for academic women scientists and engineers. Results from ADVANCE projects on campuses have facilitated consensus nationally about policies and practices that institutions may implement to help to alleviate issues, particularly for junior women scientists.Although getting women into senior and leadership positions in STEM constituted an initial impetus for ADVANCE, less emphasis was placed upon the needs of senior women scientists. Surveys of academic women scientists indicate that the issues faced by junior and senior women scientists differ significantly. The focus of ADVANCE on junior women in many ways seemed appropriate--the senior cohort of women scinetists is fed by the junior cohort of scientists; senior women serve as mentors, role models, and leaders for the junior colleagues, while continuing to struggle to achieve full status in the profession. This presentation will center on the differences in issues faced by senior compared to junior women scientists to explore whether a next step for ADVANCE should be to address needs of senior academic women scientists.

    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.

  10. Learning with Teachers; A Scientist's Perspective

    2004-12-01

    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.

    The relationship between scientific and technical information (STI), its use by aerospace engineers and scientists, and the aerospace R&D process is examined. Data are presented from studies of the role of STI in the performance and management of R&D activities and the behavior of engineers when using and seeking information. Consideration is given to the information sources used to solve technical problems, the production and use of technical communications, and the use of libraries, technical information centers, and on-line data bases.

    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

    1994-01-01

    Until the recent dissolution of the Soviet Union, the Communist Party exerted a strict control of access to and dissemination of scientific and technical information (STI). This article presents models of the Soviet-style information society and the Western-style information society and discusses the effects of centralized governmental control of information on Russian technical communication practices. The effects of political control on technical communication are then used to interpret the results of a survey of Russian and U.S. aerospace engineers and scientists concerning the time devoted to technical communication, their collaborative writing practices and their attitudes toward collaboration, the kinds of technical documents they produce and use, and their use of computer technology, and their use of and the importance to them of libraries and technical information centers. The data are discussed in terms of tentative conclusions drawn from the literature. Finally, we conclude with four questions concerning government policy, collaboration, and the flow of STI between Russian and U.S. aerospace engineers and scientists.

    The advent of global markets elevates the role and importance of culture as a mitigating factor in the diffusion of knowledge and technology and in product and process innovation. This is especially true in the Large Commercial Aircraft (LCA) sector where the production and market aspects are becoming increasingly international. As firms expand beyond their national borders, using such methods as risk- sharing partnerships, joint ventures, outsourcing, and alliances, they have to contend with national and corporate cultures. Our focus is on Japan, a 'program participant' in the production of the Boeing Company's 777; the influence of Japanese culture on the diffusion of knowledge and technology in aerospace at the national and international levels; those cultural determinants-the propensity to work together, a willingness to subsume individual interests to a greater good, and an emphasis on consensual decisionmaking-that have a direct bearing on the ability of Japanese firms to form alliances and compete in international markets; and those cultural determinants thought to influence the information- seeking behaviors and workplace communication practices of Japanese aerospace engineers and scientists. In this paper, we report selective results from a survey of Japanese and U.S. aerospace engineers and scientists that focused on workplace communications. Data are presented for the following topics: importance of and time spent communicating information, collaborative writing, need for an undergraduate course in technical communication, use of libraries, use and importance of electronic (computer) networks, and the use and importance of foreign and domestically produced technical reports.

    CNC cutting machines have become essential tools for designers and architects enabling rapid prototyping, model-building and production of high quality components. Designers often cut from new materials, discarding the irregularly shaped remains. We introduce ProjecTables, a visual augmented...... reality system for interactive packing of model parts onto sheet materials. ProjecTables enables designers to (re)use scrap materials for CNC cutting that would have been previously thrown away, at the same time supporting aesthetic choices related to wood grain, avoiding surface blemishes, and other...... relevant material properties. We conducted evaluations of ProjecTables with design students from Aarhus School of Architecture, demonstrating that participants could quickly and easily place and orient model parts reducing material waste.

    The present exploration of the diffusion of federally-funded R&D via the information-seeking behavior of scientists and engineers proceeds under three assumptions: (1) that knowledge transfer and utilization is as important as knowledge production; (2) that the diffusion of knowledge obtained through federally-funded R&D is necessary for the maintenance of U.S. preeminence in the aerospace field; and (3) that federally-funded NASA and DoD technical reports play an important, albeit as-yet undefined, role in aerospace R&D diffusion. A conceptual model is presented for the process of knowledge diffusion that stresses the role of U.S. government-funded technical reports.

  1. Communicating the Needs of Climate Change Policy Makers to Scientists

    Science.gov (United States)

    Brown, Molly E.; Escobar, Vanessa M.; Lovell, Heather

    2012-01-01

    This chapter will describe the challenges that earth scientists face in developing science data products relevant to decision maker and policy needs, and will describe strategies that can improve the two-way communication between the scientist and the policy maker. Climate change policy and decision making happens at a variety of scales - from local government implementing solar homes policies to international negotiations through the United Nations Framework Convention on Climate Change. Scientists can work to provide data at these different scales, but if they are not aware of the needs of decision makers or understand what challenges the policy maker is facing, they are likely to be less successful in influencing policy makers as they wished. This is because the science questions they are addressing may be compelling, but not relevant to the challenges that are at the forefront of policy concerns. In this chapter we examine case studies of science-policy partnerships, and the strategies each partnership uses to engage the scientist at a variety of scales. We examine three case studies: the global Carbon Monitoring System pilot project developed by NASA, a forest biomass mapping effort for Silvacarbon project, and a forest canopy cover project being conducted for forest management in Maryland. In each of these case studies, relationships between scientists and policy makers were critical for ensuring the focus of the science as well as the success of the decision-making.

    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

    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.

    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

    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

    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.

  14. From Laboratories to Classrooms: Involving Scientists in Science Education

    Science.gov (United States)

    DeVore, E. K.

    2001-12-01

    Scientists play a key role in science education: the adventure of making new discoveries excites and motivates students. Yet, American science education test scores lag behind those of other industrial countries, and the call for better science, math and technology education is widespread. Thus, improving American science, math and technological literacy is a major educational goal for the NSF and NASA. Today, funding for research often carries a requirement that the scientist be actively involved in education and public outreach (E/PO) to enhance the science literacy of students, teachers and citizens. How can scientists contribute effectively to E/PO? What roles can scientists take in E/PO? And, how can this be balanced with research requirements and timelines? This talk will focus on these questions, with examples drawn from the author's projects that involve scientists in working with K-12 teacher professional development and with K-12 curriculum development and implementation. Experiences and strategies for teacher professional development in the research environment will be discussed in the context of NASA's airborne astronomy education and outreach projects: the Flight Opportunities for Science Teacher EnRichment project and the future Airborne Ambassadors Program for NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA). Effective partnerships with scientists as content experts in the development of new classroom materials will be described with examples from the SETI Institute's Life in the Universe curriculum series for grades 3-9, and Voyages Through Time, an integrated high school science course. The author and the SETI Institute wish to acknowledge funding as well as scientific and technical support from the National Science Foundation, the National Aeronautics and Space Administration, the Hewlett Packard Company, the Foundation for Microbiology, and the Combined Federated Charities.

  19. Scientists Discover Sugar in Space

    Science.gov (United States)

    2000-06-01

    The prospects for life in the Universe just got sweeter, with the first discovery of a simple sugar molecule in space. The discovery of the sugar molecule glycolaldehyde in a giant cloud of gas and dust near the center of our own Milky Way Galaxy was made by scientists using the National Science Foundation's 12 Meter Telescope, a radio telescope on Kitt Peak, Arizona. "The discovery of this sugar molecule in a cloud from which new stars are forming means it is increasingly likely that the chemical precursors to life are formed in such clouds long before planets develop around the stars," said Jan M. Hollis of the NASA Goddard Space Flight Center in Greenbelt, MD. Hollis worked with Frank J. Lovas of the University of Illinois and Philip R. Jewell of the National Radio Astronomy Observatory (NRAO) in Green Bank, WV, on the observations, made in May. The scientists have submitted their results to the Astrophysical Journal Letters. "This discovery may be an important key to understanding the formation of life on the early Earth," said Jewell. Conditions in interstellar clouds may, in some cases, mimic the conditions on the early Earth, so studying the chemistry of interstellar clouds may help scientists understand how bio-molecules formed early in our planet's history. In addition, some scientists have suggested that Earth could have been "seeded" with complex molecules by passing comets, made of material from the interstellar cloud that condensed to form the Solar System. Glycolaldehyde, an 8-atom molecule composed of carbon, oxygen and hydrogen, can combine with other molecules to form the more-complex sugars Ribose and Glucose. Ribose is a building block of nucleic acids such as RNA and DNA, which carry the genetic code of living organisms. Glucose is the sugar found in fruits. Glycolaldehyde contains exactly the same atoms, though in a different molecular structure, as methyl formate and acetic acid, both of which were detected previously in interstellar clouds

    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...

    This document constitutes the final technical report for the National Aeronautics and Space Administration (NASA) Grant NAGW-3172. This grant was instituted to provide for the conduct of research under the Universities Space Research Association's (USRA's) Universities Earth System Scientist Program (UESSP) for the Office of Mission to Planet Earth (OMTPE) at NASA Headquarters. USRA was tasked with the following requirements in support of the Universities Earth System Scientists Programs: (1) Bring to OMTPE fundamental scientific and technical expertise not currently resident at NASA Headquarters covering the broad spectrum of Earth science disciplines; (2) Conduct basic research in order to help establish the state of the science and technological readiness, related to NASA issues and requirements, for the following, near-term, scientific uncertainties, and data/information needs in the areas of global climate change, clouds and radiative balance, sources and sinks of greenhouse gases and the processes that control them, solid earth, oceans, polar ice sheets, land-surface hydrology, ecological dynamics, biological diversity, and sustainable development; (3) Evaluate the scientific state-of-the-field in key selected areas and to assist in the definition of new research thrusts for missions, including those that would incorporate the long-term strategy of the U.S. Global Change Research Program (USGCRP). This will, in part, be accomplished by study and evaluation of the basic science needs of the community as they are used to drive the development and maintenance of a global-scale observing system, the focused research studies, and the implementation of an integrated program of modeling, prediction, and assessment; and (4) Produce specific recommendations and alternative strategies for OMTPE that can serve as a basis for interagency and national and international policy on issues related to Earth sciences.

    2015-04-01

    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. Preparing Scientists to be Community Partners

    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

    The U.S. government technical report is a primary means by which the results of federally funded research and development (R&D) are transferred to the U.S. aerospace industry. However, little is known about this information product in terms of its actual use, importance, and value in the transfer of federally, funded R&D. To help establish a body of knowledge, the U.S. government technical report is being investigated as part of the NASA/DoD Aerospace Knowledge Diffusion Research Project. In this report, we summarize the literature on technical reports and provide a model that depicts the transfer of federally funded aerospace R&D via the U.S. government technical report. We present results from two surveys of our investigation of aerospace knowledge diffusion vis-a-vis the U.S. government technical report and close with a brief overview of on-going research into aerospace knowledge diffusion focusing on the role of the industry-affiliated information intermediary.

    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

    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.

    Doctoral education has often been viewed as the pinnacle of the formal education system. How useful is doctoral training in one's later career? In an NSF-funded project, we set out to perform a study of the training, careers, and work activities of Ph.D. physical scientists. The study included both in-depth interviews and a survey sent out to a sample of Ph.D. holders 4-8 years after graduation. Come and find out the results of this study: What skills are most Ph.D. physical scientists using? What should graduate programs be teaching? Are Ph.D.'s who are working in their specific field of training happier than their counterparts working different jobs? What skills and preparation lead to future job satisfaction, perhaps the most important indicator of the "success" of graduate education? A preprint and further details can be found at the project web site at: spot.colorado.edu/ phdcarer.

    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.

    DeVore, E. K.

    2004-05-01

    "Are we alone?" "Where did we come from?" "What is our future?" These questions lie at the juncture of astronomy and biology: astrobiology. It is intrinsically interdisciplinary in its study of the origin, evolution and future of life on Earth and beyond. The fundamental concepts of origin and evolution--of both living and non-living systems--are central to astrobiology, and provide powerful themes for unifying science teaching, learning, and appreciation in classrooms and laboratories, museums and science centers, and homes. Research scientists play a key role in communicating the nature of science and joy of scientific discovery with the public. Communicating the scientific discoveries with the public brings together diverse professionals: research scientists, graduate and undergraduate faculty, educators, journalists, media producers, web designers, publishers and others. Working with these science communicators, research scientists share their discoveries through teaching, popular articles, lectures, broadcast and print media, electronic publication, and developing materials for formal and informal education such as textbooks, museum exhibits and documentary television. There's lots of activity in science communication. Yet, the NSF and NASA have both identified science education as needing improvement. The quality of schools and the preparation of teachers receive national attention via "No Child Left Behind" requirements. The number of students headed toward careers in science, technology, engineering and mathematics (STEM) is not sufficient to meet national needs. How can the research community make a difference? What role can research scientists fulfill in improving STEM education? This talk will discuss the interface between research scientists and science educators to explore effective roles for scientists in science education partnerships. Astronomy and astrobiology education and outreach projects, materials, and programs will provide the context for

    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

  18. Cassini revisited by the Cassini-Huygens probe: dynamical and photometric study of the rings with the ISS images

    International Nuclear Information System (INIS)

    Deau, Estelle

    2007-12-01

    In the Solar system, the planetary rings represent a fantastic opportunity of studying a majority of phenomena taking place in the thin discs. One can find discs at all redshifts and on all scales of the Universe. Planetary discs are very different: among the Jovian rings, one finds a halo of fine and diffuse dust; the rings of Uranus are very compact, like radially confined strings and the system of rings of Neptune consists of azimuthally stable arcs. However our interest goes on Saturn which has the most complex and widest system of rings known to date: 484 000 km and a vertical extension which increases with the distance to Saturn (typically less than 1 km to 10 000 km). The interest of such a matter organization around Saturn plus its many moons (more than one forty including 8 of a size of several hundreds kilometers) gave birth to the exploration mission CASSINI, supposed to allow the development and the refinement of models set up at the flybies of the two interplanetary probes VOYAGER. The CASSINI Mission began its nominal tour on January, 15 2005 after the orbital insertion the 1 July 2004 and the dropping of HUYGENS probe on january, 14 2005 on Titan's surface. The purpose of this thesis consists to revisit two subjects unsolved of long date in the photometric and dynamic behaviours of the Saturn's rings. In a first part, we try to solve the problem of accretion of matter within the Roche limit by studying the F ring. This ring, since its discovery in 1979 by Pioneer 11, is involved in a most various dynamic theories to explain its complex multi-radial structure and its variable azimuthal structure. We showed that the multi-radial structure of this ring can be understood by the existence of a spiral which is rolled up around a central area, bright, eccentric and inclined: the core. The lifespan of this spiral is not the same one as the core, suggesting that the processes which create the spiral are periodic. Moreover, we showed that the structure of the

    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.

    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.

    2011-12-01

    Science education reform since the mid-1990's has called for a "new way of teaching and learning about science that reflects how science itself is done, emphasizing inquiry as a way of achieving knowledge and understanding about the world" (NRC, 1996). Scientists and engineers, experts in inquiry thinking, have been called to help model these practices for students and demonstrate scientific habits of mind. The question, however, is "how best to involve these experts?" given the very real challenges of limited availability of scientists, varying experience with effective pedagogy, widespread geographic distribution of schools, and the sheer number of students involved. Technology offers partial solutions to enable Student-Scientist Interactions (SSI). The FLEXE Project has developed online FLEXE Forums to support efficient, effective SSIs, making use of web-based and database technology to facilitate communication between students and scientists. More importantly, the FLEXE project has approached this question of "how best to do this?" scientifically, combining program evaluation with hypothesis-based research explicitly testing the effects of such SSIs on student learning and attitudes towards science. FLEXE Forums are designed to showcase scientific practices and habits of mind through facilitated interaction between students and scientists. Through these Forums, students "meet" working scientists and learn about their research and the environments in which they work. Scientists provide students with intriguing "real-life" datasets and challenge students to analyze and interpret the data through guiding questions. Students submit their analyses to the Forum, and scientists provide feedback and connect the instructional activity with real-life practice, showcasing their activities in the field. In the FLEXE project, Forums are embedded within inquiry-based instructional units focused on essential learning concepts, and feature the deep-sea environment in contrast

    Title: Teenagers as scientist - Learning by doing or doing without learning? Authors: Dr. Suzanne Kapelari* and Elsabeth Carli*, Ulrike Tappeiner** *Science Educaton Center,**Institute of Ecology,University Innsbruck, Austria The PISA (2006-2007) Assessment Framework asks for"…. the development of a general understanding of important concepts and explanatory framework of science, of the methods by which science derives evidence to support claims for its knowledge and of the strength and limitations of science in the real world….". To meet these requirements pupils are eventually asked to engage in "working like scientists learning activities" at school or while visiting informal learning institutions. But what does it mean in a real life situation? An ambitious project call named "Sparkling Science" was launched by the Austrian Federal Ministry of Science and Research in 2008, asking scientists to run their research in tight co-operation with local teachers and pupils. Although this would be enough of a challenge anyway, the ultimate goals of these projects are to achieve publishable scientific results in the particular field. The project design appears to be promising. Pupils and teachers are invited to gain first hand experience as part of a research team investigating current research questions. Pupils experience science research first hand, explore laboratories and research sites, gather data, discuss findings, draw conclusions and finally publish them. They set off on an exciting two years journey through a real scientific project. Teachers have the unique opportunity to get insight into a research project and work closely together with scientists. In addition teachers and pupils have the opportunity to gain first hand knowledge about a particular topic and are invited to discuss science matters on the uppermost level.

    Scientists spend years training in their scientific discipline and are well versed the literature, methods, and innovations in their own field. Many scientists also take on teaching responsibilities with little formal training in how to implement their courses or assess their students. There is a growing body of literature of what students know in space science courses and the types of innovations that can work to increase student learning but scientists rarely have exposure to this body of literature. For scientists who are interested in more effectively understanding what their students know or investigating the impact their courses have on students, there is little guidance. Undertaking a more formal study of students poses more complexities including finding robust instruments and employing appropriate data analysis. Additionally, formal research with students involves issues of privacy and human subjects concerns, both regulated by federal laws.This poster details the important decisions and issues to consider for both course evaluation and more formal research using a course developed, facilitated, evaluated and researched by a hybrid team of scientists and science education researchers. HabWorlds, designed and implemented by a team of scientists and faculty at Arizona State University, has been using student data to continually improve the course as well as conduct formal research on students’ knowledge and attitudes in science. This ongoing project has had external funding sources to allow robust assessment not available to most instructors. This is a case study for discussing issues that are applicable to designing and assessing all science courses. Over the course of several years, instructors have refined course outcomes and learning objectives that are shared with students as a roadmap of instruction. The team has searched for appropriate tools for assessing student learning and attitudes, tested them and decided which have worked, or not, for

  14. Inexpensive Ultrasound Demonstrations as Analogs of Radio Diffraction in the field : Huygens Probe Bistatic experiment on Titan and the Sea Interferometer (Invited)

    2013-12-01

    The wave nature of electromagnetic radiation can be exploited in a number of astronomical and remote sensing methods, but is often challenging to visualize in the classroom. One approach with conveniently-inexpensive components is to use sound as an analog. Readily-available ultrasonic transducers at 40 kHz can be driven with a 555 oscillator and received intensity detected with an op-amp and visualized with a digital voltmeter, a lightbulb, or even acoustically. The wavelength of 9mm is convenient for tabletop experiments, with a relevant example being Lloyds Mirror, the interference of a direct wave from a source just above a surface with the reflected wave. As a distant receiver moves in angle through this interference pattern, a series of peaks and nulls in recorded intensity can be interpreted as the height of the transmitter and the reflectivity (i.e. with some assumptions, the roughness) of the reflecting surface. This $10 experiment will be demonstrated at the poster. Such an observation was (serendipitously) made in 2005 after the landing of the Huygens probe on the surface of Titan, where the radio signal measured by Cassini as it set on the horizon as seen from the probe underwent sharp dips in strength that were inverted into a precise measurement of the post-impact probe height. A similar technique in reverse was applied a half century earlier in early Australian radio astronomy to measure the position and width of astrophysical sources from a single clifftop antenna. Ultrasound can be convenient to emulate other radio work, exploiting Doppler effects and (for pulsed sources, like those used in rangers for amateur robotics) propagation time rather than diffraction. Some experiments on tracking Frisbees as an analog for measuring planetary winds by tracking descent probes, and on bistatic delay/Doppler scatterometry as in the CYGNSS GPS-based experiment to measure hurricane winds via sea state, will also be discussed. Huygens probe on the surface of

    500 Women Scientists is a grassroots organization formed in late 2016 to empower women to grow to their full potential in science, increase scientific literacy through public engagement, and advocate for science and equality. Our organization is global but we focus on building community relationships through local action. Our "pods," or local chapters, focus on issues that resonate in their communities, rooted in our mission and values. Pod members meet regularly, develop a support network, make strategic plans, and take action. In less than a year, 500 Women Scientists has already formed important partnerships and begun to work on local, regional and national projects. Nationally, we partnered with The Cairn Project to raise money to support girls in science. In an effort led by the DC pod, our members sent postcards sharing stories of how the EPA protects their communities in the #OurEPA postcard campaign. Pods have also participated in marches, including the Women's March, the March for Science and the People's Climate March. The "Summer of Op-Ed" campaign catalyzed pods and individuals to write to their local newspapers to speak up for funding science, climate change action, and general science advocacy. We have organized "strike-teams" that are working on local issues like education, the environment, climate change, and equal access to science. Additionally, pod members serve as mentors, participate in local events, hold workshops and partner with local organizations. As women scientists, we are in the position to take action to increase diversity in science and to draw attention to unacknowledged structural biases that negatively impact historically under-represented groups. 500 Women Scientists enables women in science to embrace this advocacy role, both within our scientific system and within our local communities.

    The bilateral project of Belarus and Germany was commissioned on 1.04.1993 and is placed under the scientific guidance of the Gemeinschaftsausschuss Strahlenforschung. In the framework of the project part devoted to ``therapy and medical training``, covering the period from 1.04.1993 until 31.03.1996, all in all 99 children from Belarus suffering from advanced-stage tumors of the thyroid received a special radio-iodine therapy in Germany. In about 60% of the children complete removal of the tumor was achieved. Another task of the project was to train over the reporting period 41 doctors and physicists from Belarus in the fields of nuclear medical diagnostic evaluation and therapy of thyroid tumors. The project part ``biological dosimetry`` was to investigate the role of micronuclei in peripheral lymphocytes, and whether their presence in the lymphocytes permits to derive information on the radiation dose received even several years after the reactor accident. The scientists also exmained the role of the micronuclei in follow-up examinations of the radio-iodine therapy. Further studies used the relatively large number of tumors in the children, as compared to the literature available until the accident, to examine whether there are specific mutation patterns to be found in tumot suppressor genes (p-53) in thyroid tumors which might be used as indicators revealing radiation-induced onset of tumor growth. The project part ``retrospective dosimetry and risk analysis`` was in charge of detecting information answering the question of whether the release of I-131, suspected to be critical nuclide, really was the cause of enhanced incidence of thyroid tumors in the children. The project part ``coordination and examination center at Minsk`` was to establish and hold available the support required by the GAST project participants.

    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.

  3. 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...

    2015-01-01

    Magdolna Hargittai uses over fifteen years of in-depth conversation with female physicists, chemists, biomedical researchers, and other scientists to form cohesive ideas on the state of the modern female scientist. The compilation, based on sixty conversations, examines unique challenges that women with serious scientific aspirations face. In addition to addressing challenges and the unjustifiable underrepresentation of women at the higher levels of academia, Hargittai takes a balanced approach by discussing how some of the most successful of these women have managed to obtain professional success and personal happiness. Women Scientists portrays scientists from different backgrounds, different geographical regions-eighteen countries from four continents-and leaders from a variety of professional backgrounds, including eight Nobel laureate women. The book is divided into three sections: "Husband and Wife Teams," "Women at the Top," and "In High Positions." Hargittai uses her own experience to introduce her fi...

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

    Science.gov (United States)

    Subramaniam, Karthigeyan; Esprívalo Harrell, Pamela; Wojnowski, David

    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.

  17. To Crowdfund Research, Scientists Must Build an Audience for Their Work.

    Directory of Open Access Journals (Sweden)

    Jarrett E K Byrnes

    Full Text Available As rates of traditional sources of scientific funding decline, scientists have become increasingly interested in crowdfunding as a means of bringing in new money for research. In fields where crowdfunding has become a major venue for fundraising such as the arts and technology, building an audience for one's work is key for successful crowdfunding. For science, to what extent does audience building, via engagement and outreach, increase a scientist's abilities to bring in money via crowdfunding? Here we report on an analysis of the #SciFund Challenge, a crowdfunding experiment in which 159 scientists attempted to crowdfund their research. Using data gathered from a survey of participants, internet metrics, and logs of project donations, we find that public engagement is the key to crowdfunding success. Building an audience or "fanbase" and actively engaging with that audience as well as seeking to broaden the reach of one's audience indirectly increases levels of funding. Audience size and effort interact to bring in more people to view a scientist's project proposal, leading to funding. We discuss how projects capable of raising levels of funds commensurate with traditional funding agencies will need to incorporate direct involvement of the public with science. We suggest that if scientists and research institutions wish to tap this new source of funds, they will need to encourage and reward activities that allow scientists to engage with the public.

    2013-12-01

    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.

    In a rich and fascinating history John Cornwell tells the epic story of Germany's scientists from the First World War to the collapse of Hitler's Reich. He shows how Germany became the world's Mecca for inventive genius, taking the lion's share of Nobel awards, before Hitler's regime hijacked science for wars of conquest and genocidal racism. Cornwell gives a dramatic account of the wide ranging Nazi research projects, from rockets to nuclear weapons; the pursuit of advanced technology for irrational ends, concluding with with penetrating relevance for today: the inherent dangers of science without conscience.

    2017-04-01

    Full Text Available Over the last several decades, scholars working on Indigenous topics have faced increasing pressure to engage in research that promotes social justice and results in formal partnerships with Indigenous communities. In this article, we argue that non-community-based research, in which the researcher exercises academic autonomy over the project, still has a role to play in Indigenous-focused research, depending on the research question, topic, and situation at hand. We explore this argument from the perspective of political scientists who study Indigenous–settler political relations in Canada.

    We discuss how we designed the Open Targets Platform (www.targetvalidation.org), an intuitive application for bench scientists working in early drug discovery. To meet the needs of our users, we applied lean user experience (UX) design methods: we started engaging with users very early and carried out research, design and evaluation activities within an iterative development process. We also emphasize the collaborative nature of applying lean UX design, which we believe is a foundation for success in this and many other scientific projects. Copyright © 2018 The Authors.

The characterisation of Titan atmosphere physical properties. Space Sci. Rev. 104, 395-431] was a very complete instrument suite installed on board the Huygens probe, the planetary lander of the Cassini Huygens Mission to Saturn system, which successfully completed its mission in January 2005. HASI comprised a set of accelerometers, temperature sensors, pressure transducers and permittivity analysers aimed at the investigation of Titan atmosphere, which were fully operative during a several hour-long parachuted descent from an altitude of 157 km to planetary surface. Accelerometers were the only instruments activated earlier, just after Cassini separation, and recorded data during all the mission phases from atmospheric entry to landing, providing essential information for elaborating probe trajectory as well as Titan atmospheric profiles [G. Colombatti, et al. Reconstruction of the trajectory of the Huygens probe using the Huygens Atmospheric Structure Instrument, this same PSS issue]. Although not specifically designed for monitoring very fast dynamic events, HASI accelerometers have also recorded the trace of probe impact with the planetary surface, building up along with the data from Huygens Surface Science Package (SSP) instrument [ Zarnecki, J.C., Leese, M.R., Garry, J.R.C., Ghafoor, N.A.L., Hathi, B., 2002.

    2016-01-01

    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.

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.

    Several studies have indicated that scientists are likely to have an outlook on both facts and values that are different to that of lay people in important ways. This is one significant reason it is currently believed that in order for scientists to exercise a reliable ethical reflection about their research it is necessary for them to engage in dialogue with other stakeholders. This paper reports on an exercise to encourage a group of scientists to reflect on ethical issues without the presence of external stakeholders. It reports on the use of a reflection process with scientists working in the area of animal disease genomics (mainly drawn from the EADGENE EC Network of Excellence). This reflection process was facilitated by using an ethical engagement framework, a modified version of the Ethical Matrix. As judged by two criteria, a qualitative assessment of the outcomes and the participants' own assessment of the process, this independent reflective exercise was deemed to be successful. The discussions demonstrated a high level of complexity and depth, with participants demonstrating a clear perception of uncertainties and the context in which their research operates. Reflection on stakeholder views and values appeared to be embedded within the discussions. The finding from this exercise seems to indicate that even without the involvement of the wider stakeholder community, valuable reflection and worthwhile discourse can be generated from ethical reflection processes involving only scienitific project partners. Hence, the previous assumption that direct stakeholder engagement is necessary for ethical reflection does not appear to hold true in all cases; however, other reasons for involving a broad group of stakeholders relating to governance and social accountability of science remain.

    The Systems Engineering (SE) staff at LBNL has generated the following artifacts to assist projects with implementing a systems approach: (1) The present document that focuses on the what, why, and when of SE. It also provides a simple case-study to illustrate several SE tasks. (2) A web site with primary emphasis on the project life-cycle and workflow, (http://www-eng.LBNL.gov/Systems/index.html). It includes: SE guidelines and principles; A list of in-house tools; Templates; Case studies with ''how to'' examples; and Links to useful SE material. These sources are living documents to be updated as necessary. The viewpoint adopted in this document is that what LBNL engineers and scientists need is a set of principles and guiding practices for developing R and D systems rather than a ''cookbook''. There are many excellent ''how to'' resources such as the ''INCOSE Systems Engineering Handbook'' to guide those in search of more details. The SE staff is another resource available to consult and support projects. This document specifies SE principles and activities that are applicable to all LBNL projects independent of their specific differences. Each project should tailor the SE implementation to meet its individual needs and culture including project-specific resources, procedures, products, and tools.

    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

  16. 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.

  1. Superheroes and supervillains: reconstructing the mad-scientist stereotype in school science

    Science.gov (United States)

    Avraamidou, Lucy

    2013-04-01

    Background. Reform recommendations around the world call for an understanding about the nature of science and the work of scientists. However, related research findings provide evidence that students hold stereotypical views of scientists and the nature of their work. Purpose The aim of this case study was to examine the impact of an intervention on 15 elementary school students' views of scientists. Sample An urban, fifth-grade, European elementary school classroom defined the context of this study. Design and method The intervention was an 11-week-long investigation of a local problem concerning water quality. In carrying out this investigation the students collaborated with a young metrology scientist to collect and analyse authentic data that would help them to construct a claim about the quality of the water. The students' initial views of scientists were investigated through a drawing activity, classroom discussions and interviews. Results Analysis of these data indicated that all students but one girl held very stereotypical views on scientists and the nature of their work. Analysis of interviews with each student and classroom discussions after the intervention illustrated that they reconstructed their stereotypical views of scientists and the nature of their work owing to their personal engagement in the investigation and their collaboration with the scientist. Conclusions The findings of this study suggest that more in-depth study into project-based approaches, out-of-school learning and school-scientist partnerships is warranted, for the purpose of determining appropriate pedagogies that support students in developing up-to-date understanding about scientists and the nature of their work.

  2. Media and the making of scientists

    Science.gov (United States)

    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

    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.

    SunBlock `99 is a Web-based Public Understanding of Science and educational project which seeks to present the very latest solar research as seen through the eyes of young British scientists. These ``solar guides'' discuss not only their scientific interests, but also their extra-curricular activities and the reasons they chose scientific careers; in other words the human face of scientific research. The SunBlock '99 pages gather a range of solar images and movies from current solar space observatories and discuss the underlying physics and its relationship to the school curriculum. The instructional level is pitched at UK secondary school children (aged 13-16 years). It is intended that the material should not only provide a visually appealing introduction to the study of the Sun, but that it should help bridge the often wide gap between classroom science lessons and the research scientist `out in the field'. SunBlock '99 is managed by a team from the Rutherford Appleton Laboratory and the Universities of St Andrews and Cambridge, together with educational consultants. The production has, in part, been sponsored by PPARC and the Millennium Mathematics Project. Web site addresss: http://www.sunblock99.org.uk

    Morente et al. have recently revisited the VLF electric field measurements made with the Permittivity, Wave and Altimetry (PWA) instrument during the descent of the Huygens Probe through the atmosphere of Titan. They assert that they have identified several harmonics of the transverse resonance mode of the surface?]ionosphere cavity, which would prove the existence of an electrical activity in the atmosphere of the largest satellite of Saturn. We refute this finding on the basis that it results from an artifact due to an improper analysis of the data set. [2] The investigators of the Permittivity, Wave and Altimetry (PWA) experiment on the Huygens Probe have reported the extremely low frequency (ELF) and very low frequency (VLF) electric signals recorded during the descent through the atmosphere of Titan. The PWA data are archived in the Planetary Science Archive (PSA) of ESA, and an extensive description of the instrument is at the disposal of the scientific community. Morente and his coworkers have revisited this data set and reported the results of their investigations in two papers. In a first paper, they claim that they have detected in the ELF range (0.100 Hz) several harmonics of a global resonance allegedly generated by lightning activity in the spherical cavity guide formed by the surface of Titan and the inner boundary of the ionosphere, a phenomenon similar to the Schumann resonance observed at EartH In the second paper dedicated to the VLF electric signal recorded by PWA, in the range 0.10 kHz, they argue that they can also bring out the transverse resonance and its harmonics, a more local phenomenon that develops around the excitation source and whose frequency is controlled by the separation between Titan?fs surface and the inner ionospheric boundary. [3] The PWA investigators have analyzed the narrowband ELF signal at about 36 Hz effectively observed during the entire descent. They have not endorsed, however, the alternative approach of Morente et al

    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.

  9. Scientist-Practitioner Engagement to Inform Regional Hydroclimate Model Evaluation

    Science.gov (United States)

    Jones, A. D.; Jagannathan, K. A.; Ullrich, P. A.

    2017-12-01

    Water mangers face significant challenges in planning for the coming decades as previously stationary aspects of the regional hydroclimate shift in response to global climate change. Providing scientific insights that enable appropriate use of regional hydroclimate projections for planning is a non-trivial problem. The system of data, models, and methods used to produce regional hydroclimate projections is subject to multiple interacting uncertainties and biases, including uncertainties that arise from general circulation models, re-analysis data products, regional climate models, hydrologic models, and statistical downscaling methods. Moreover, many components of this system were not designed with the information needs of water managers in mind. To address this problem and provide actionable insights into the sources of uncertainty present in regional hydroclimate data products, Project Hyperion has undertaken a stakeholder engagement process in four case study water basins across the US. Teams of water managers and scientists are interacting in a structured manner to identify decision-relevant metrics of model performance. These metrics are in turn being used to drive scientific investigations to uncover the sources of uncertainty in these quantities. Thus far, we have found that identification of climate phenomena of interest to stakeholders is relatively easy, but translating these into specific quantifiable metrics and prioritizing metrics is more challenging. Iterative feedback among scientists and stakeholders has proven critical in resolving these challenges, as has the roles played by boundary spanners who understand and can speak to the perspectives of multiple professional communities. Here we describe the structured format of our engagement process and the lessons learned so far, as we aim to improve the decision-relevance of hydroclimate projections through a collaborative process.

  13. 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.

    Dohaney, J. A.; Hudson-Doyle, E.; Brogt, E.; Wilson, T. M.; Kennedy, B.

    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.

  13. Nobelist TD LEE Scientist Cooperation Network and Scientist Innovation Ability Model

    Directory of Open Access Journals (Sweden)

    Jin-Qing Fang

    2013-01-01

    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.

    2014-11-01

    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.

    St Ledger, John W. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2017-02-01

    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.

  17. Kristian Birkeland the first space scientist

    CERN Document Server

    Egeland, Alv

    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...

  18. Differential forms for scientists and engineers

    Science.gov (United States)

    Blair Perot, J.; Zusi, Christopher J.

    2014-01-01

    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.

    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.

  6. The scientist's role in the nuclear debate

    1981-01-01

    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

    Noel-Storr, Jacob; Terwilliger, Michael; InsightSTEM Teacher-Scientist-Communicator-Learner Partnerships Team

    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.

  8. Scientists in the public sphere: Interactions of scientists and journalists in Brazil.

    Massarani, Luisa; Peters, Hans P

    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

    2015-04-01

    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

    2005-05-01

    The Stanford Solar Observatories Group and Haas Center for Public Service have created an innovative model for scientist-educator partnerships in which science students are trained and mentored by public service education professionals to create outreach events for local communities. The program, Science in Service, is part of the EPO plan for the Solar Group's participation in NASA's Solar Dynamics Observatory mission. Based on the principles of service learning, the Science in Service Program mentors college science students in best practices for communicating science and engages these students in public service projects that center on teaching solar science. The program goals are to - Enhance and expand the learning experiences that pre-college students, from underserved and underrepresented groups in particular, have in science and technology. - Promote leadership in community service in the area of science and engineering among the next generation of scientists and engineers, today's undergraduate students. - Encourage science and engineering faculty to think creatively about their outreach requirements and to create a community of faculty committed to quality outreach programs. This talk will describe the unique advantages and challenges of a research-public service partnership, explain the structure of Stanford's Science in Service Program, and present the experiences of the undergraduates and the outreach communities that have been involved in the program.

    2017-10-01

    This examination of an important paper by Sydney Ross is the first in a projected series of occasional reflections on 'Annals of Science Classic Papers' that have had enduring utility within the field of history of science and beyond. First the messages of the paper are examined, some well known but others, particularly Ross's own contemporary concerns about the use of the word 'scientist', less so. The varied uses made of the paper by scholars are then traced before Ross's biography is examined in order to try to understand how a figure professionally marginal to the field of history of science came to write such a significant piece. Ross's interest in the topic appears to have been informed by a romantically tinged scientific progressivism and a deep concern with the importance of linguistic precision in science and in public affairs. The inspirations of the author and the interests of his audience have been only partially aligned, but the paper's insights remain of broad historical interest and have wider ramifications since the denotation 'scientist' and its proper application are much debated today in contests over the authority of science.

    Professional groups, such as IFAPP (International Federation of Pharmaceutical Physicians and Pharmaceutical Medicine), are expected to produce the defined core competencies to orient the discipline and the academic programs for the development of future competent professionals and to advance the profession. On the other hand, PharmaTrain, an Innovative Medicines Initiative project, has become the largest public-private partnership in biomedicine in the European Continent and aims to provide postgraduate courses that are designed to meet the needs of professionals working in medicines development. A working group was formed within IFAPP including representatives from PharmaTrain, academic institutions and national member associations, with special interest and experience on Quality Improvement through education. The objectives were: to define a set of core competencies for pharmaceutical physicians and drug development scientists, to be summarized in a Statement of Competence and to benchmark and align these identified core competencies with the Learning Outcomes (LO) of the PharmaTrain Base Course. The objectives were successfully achieved. Seven domains and 60 core competencies were identified and aligned accordingly. The effective implementation of training programs using the competencies or the PharmaTrain LO anywhere in the world may transform the drug development process to an efficient and integrated process for better and safer medicines. The PharmaTrain Base Course might provide the cognitive framework to achieve the desired Statement of Competence for Pharmaceutical Physicians and Drug Development Scientists worldwide.

    Since the early 1980s, a number of initiatives have been undertaken worldwide which have involved scientists and teachers working together in projects designed to support the science learning of students. Many of these have attempted to establish school-scientist partnerships. In these, scientists, teachers, and students formed teams engaged in mutually beneficial science-based activities founded on principles such as equal recognition and input, and shared vision, responsibility and risk. This article uses two partnership programmes run by a New Zealand Science Research Institute, to illustrate the challenges faced by scientists and teachers as they attempted to forge meaningful and effective partnerships. It argues that achieving the theorised position of a shared partnership space at the intersection of the worlds of scientists and teachers is problematic, and that scientists must instead be prepared to penetrate deeply into the world of the classroom when undertaking any such interactions. Findings indicate epistemological differences, curriculum and school systems and issues, and teacher efficacy and science knowledge significantly affect the process of partnership formation. Furthermore, it is argued that a re-thinking of partnerships is needed to reflect present economic and education environments, which are very different to those in which they were originally conceived nearly 30 years ago. It suggests that technology has an important role to play in future partnership interactions.

    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.

  19. Thresholds and Glass Ceilings: Career Pattern of Women Scientists

    The Project Access study examined the careers of men and women who had received prestigious postdoctoral fellowships and thus were presumably of about equal promise at the start of their professional careers. Had the women scientists in this elite group overcome a threshold beyond which they proceeded on equal footing with their male counterparts; or did a glass ceiling impede their careers? We found gender differences in career outcomes in the group we studied (699 questionnaires, 200 interviews), but these differences varied considerably by scientific discipline. Moreover, the career disparities for women, as a group, appear now to result chiefly from a series of subtle but identifiable and sometimes counterintuitive impediments as well as from slight gender differences in socialization. Each disadvantage by itself may be small, but in their accumulation they significantly influence women's careers.

  20. The character of scientists in the Nobel Prize speeches.

    2018-05-01

    This essay describes the ethos (i.e. the character projected to specific audiences) of the 25 Nobel Lectures in Physics, Chemistry, and Physiology or Medicine given in 2013-2015 and the 15 Presentation Speeches given at the Nobel Banquets between 2011 and 2015. A thematically focused qualitative analysis grounded in theories of epideictic discourse indicates the Nobel speakers demonstrated a range of strategies for and degrees of success in negotiating the tensions created by the implicit demands of ceremonial speeches, the scientific emphasis on didactic style and research content, and the different potential audiences (scientific experts and interested publics). Relatively few speeches explicitly displayed goodwill toward humanity instead of primarily toward the scientific community. Some speakers emphasized qualities of goodness in line with social values shared by broad audiences, but some reinforced stereotypes of scientists as anti-social. Speakers were variable in their ability to bridge the substantial gaps in resources for shared good sense.

    NASA GSFC Education is directly involved with scientists in studies of ice and snow as they seek to gain insight into the effects of snow and ice on the Earth's weather and climate. In parts of the world the water equivalent in the snow has significant cultural and economic consequences. Better techniques for remote determination of water content in the snowpacks depend on the in situ validation of satellite remote sensing. These in situ measurements and supporting lab studies are used by those who support the NASA efforts, and evaluate avalanche hazard are the same measurements and techniques that we teach in our teacher as scientist education program held annually at Lake Placid,New York -the home of the 1932 and 1980 winter Olympics. We developed this program called HOW (History of Winter) in conjunction with scientist Peter Wasilewski, GSFC Laboratory for Extraterrestrial Physics. The program brings together teachers and scientists (the latter having 55 expeditions to the Polar regions and numerous years of Lake Ice studies in their backgrounds) to broadly decipher the history of winter embedded in the measurable record of snowfall and details in lake ice. The concept is to have scientists create the mindset and framework for teacher scientists who can then facilitate the motivation of student scientists via an inquiry based structure. Additionally, we strive to have students view their science teachers not only as teachers, but also as scientists who are actively engaged in research projects in order to provide a stimulus to the students to not only consider teaching as an exciting career, but also science itself. This session will describe how the teachers are directly involved annually in the science role during a 7 day campaign in February, and then follow up with their students upon returning to the classroom. The structure of the program and protocols will be described.

    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.

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

    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.

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

    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.

    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

  10. Scientists Interacting With University Science Educators

    Spector, B. S.

    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

    2004-12-01

    Many scientists, when faced with developing an education and outreach plan for their research proposals, are unclear on what kinds of impacts they can have on broader non scientist audiences. Many scientists feel their only options are to develop a website or invite a teacher to get involved in their sampling or research cruises. Scientists, who are constrained by time and resources, are not aware of the range of education and outreach options available to them and of the great value their involvement can bring to the public. In an recent survey at the National Science Foundation sponsored ORION conference (January 2004), respondents stated that the greatest public benefits to having scientists involved in public education are (1) that they can present the benefits and relevance of research (26%), (2) focus awareness on environmental issues (26%), (3) serve as models for teachers and motivators for children (25%) and (4) increase public understanding, awareness and appreciation of science (about 22%). As a member of the Mid-Atlantic Center for Ocean Sciences Education Excellence (MACOSEE), the Institute of Marine & Coastal Sciences (IMCS) at Rutgers University is dedicated to helping scientists and educators realize the benefits of working together to advance ocean discovery and make known the vital role of the ocean in our lives. A website called "Scientist Connection" (www.macosee.net) was developed to help busy scientists choose a role in education and outreach that will make the most of their talent and time. The goal of the web site is to help scientists produce a worthwhile education project that complements and enriches their research. In this session, the author will present two case studies that demonstrate very different but effective approaches to scientist's involvement in education and outreach projects. In the first case, we will chronicle how a team of biologists and oceanographers in the Rutgers University, Coastal Ocean Observation Laboratory (or

  13. VLBA Scientists Study Birth of Sunlike Stars

    Science.gov (United States)

    1999-06-01

    Three teams of scientists have used the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope to learn tantalizing new details about how Sun-like stars are formed. Young stars, still growing by drawing in nearby gas, also spew some of that material back into their surroundings, like impatient infants that eat too quickly. The VLBA observations are giving astronomers new insights on both processes -- the accretion of material by the new stars and the outflows of material from them. "For the first time, we're actually seeing what happens right down next to the star in these young systems," said Mark Claussen, of the National Radio Astronomy Observatory (NRAO) in Socorro, NM. Claussen and other researchers announced their findings at the American Astronomical Society's meeting in Chicago. Material attracted by a young star's gravitational pull forms a flat, orbiting disk, called an accretion disk, in which the material circles closer and closer to the star until finally drawn into it. At the same time, material is ejected in "jets" speeding from the poles of the accretion disk. "The VLBA is showing us the first images of the region close to the star where the material in these jets is accelerated and formed into the `beams' of the jet," Claussen said. "We don't understand the details of these processes well," Claussen said. "These VLBA research projects are beginning to help unravel the mysteries of how stars like the Sun form." The teams are observing clumps of water vapor that naturally amplify radio emissions to see details smaller than the orbit of Mercury in young stellar systems as well as track gas motions. The clumps of gas are called masers, and amplify radio emission in much the same way that a laser amplifies light emission. "These images are just fantastic," said Al Wootten of NRAO in Charlottesville, VA. The maser clumps or "spots," emitting radio waves at a specific wavelength, can be tracked as they move over time.

    The relationship between the use of U.S. government technical reports by U.S. aerospace engineers and scientists and selected institutional and sociometric variables was investigated. The methodology used for this study was survey research. Data were collected by means of a self-administered mail questionnaire. The approximately 34,000 members of the American Institute of Aeronautics and Astronauts (AIAA) served as the study population. The response rate for the survey was 70 percent. A dependent relationship was found to exist between the use of U.S. government technical reports and three of the institutional variables (academic preparation, years of professional aerospace work experience, and technical discipline). The use of U.S. government technical reports was found to be independent of all of the sociometric variables. The institutional variables best explain the use of U.S. government technical reports by U.S. aerospace engineers and scientists.

    Egeland, A.; Burke, W. J.

    2005-05-01

    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 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.

  19. 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.

  20. A data model for environmental scientists

    2008-12-01

    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.

  1. 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 GLOBE Program (www.globe.gov) involves students and scientists in a worldwide environmental data collection effort. The GLOBE ONE field campaign (www.globe.gov/globeone) represents a model for a focused implementation of GLOBE via a geographically-specific project. The campaign, which occurred in Black Hawk County, Iowa from February 2004 to February 2006, was developed by GLOBE Principal Investigators (PIs), the GLOBE Program Office, and GLOBE Iowa. The central scientific objective was to compare quantitatively the environmental effects of various soil tillage techniques. In addition, student research projects were supported that spanned a variety of Earth science topics. The campaign established a partnership between students and scientists to collect a structured, multidisciplinary data set and also increase GLOBE visibility. The fact that GLOBE ONE occurred in a focused geographic area made it necessary to form a network for local support. This started with choosing an active GLOBE partner, namely the Iowa Academy of Science, who had the ability to oversee the local implementation of such a project. Once this partner was chosen, additional local groups needed to be recruited to support the project. The local network included K-12 schools, the County Conservation Board, the University of Northern Iowa, Hawkeye Community College, and community volunteers. This network collected data via automated instrumentation, first-hand observations, and through special events organized with a focus on a specific measurement. The first major step in supporting student research was a teacher training workshop held in March of 2006 that helped to provide tools for, and increase comfort levels with, promoting scientific inquiry in the classroom. Student-scientists interactions were promoted via scientist visits, video conferences, letters, and email exchanges. The culminating event was a Student Research Symposium held in February 2006 which gave students and scientists a

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

    Citizen science initiatives encourage volunteer participants to collect and interpret data and contribute to formal scientific projects. The growth of virtual citizen science (VCS), facilitated through websites and mobile applications since the mid-2000s, has been driven by a combination of software innovations and mobile technologies, growing scientific data flows without commensurate increases in resources to handle them, and the desire of internet-connected participants to contribute to collective outputs. However, the increasing availability of internet-based activities requires individual VCS projects to compete for the attention of volunteers and promote their long-term retention. We examined program and platform design principles that might allow VCS initiatives to compete more effectively for volunteers, increase productivity of project participants, and retain contributors over time. We surveyed key personnel engaged in managing a sample of VCS projects to identify the principles and practices they pursued for these purposes and led a team in a heuristic evaluation of volunteer engagement, website or application usability, and participant retention. We received 40 completed survey responses (33% response rate) and completed a heuristic evaluation of 20 VCS program sites. The majority of the VCS programs focused on scientific outcomes, whereas the educational and social benefits of program participation, variables that are consistently ranked as important for volunteer engagement and retention, were incidental. Evaluators indicated usability, across most of the VCS program sites, was higher and less variable than the ratings for participant engagement and retention. In the context of growing competition for the attention of internet volunteers, increased attention to the motivations of virtual citizen scientists may help VCS programs sustain the necessary engagement and retention of their volunteers. © 2016 Society for Conservation Biology.

    Kantorovich, Lev

    2016-01-01

    This book, the first in a two part series, covers a course of mathematics tailored specifically for physics, engineering and chemistry students at the undergraduate level. It is unique in that it begins with logical concepts of mathematics first encountered at A-level and covers them in thorough detail, filling in the gaps in students' knowledge and reasoning. Then the book aids the leap between A-level and university-level mathematics, with complete proofs provided throughout and all complex mathematical concepts and techniques presented in a clear and transparent manner. Numerous examples and problems (with answers) are given for each section and, where appropriate, mathematical concepts are illustrated in a physics context. This text gives an invaluable foundation to students and a comprehensive aid to lecturers. Mathematics for Natural Scientists: Fundamentals and Basics is the first of two volumes. Advanced topics and their applications in physics are covered in the second volume.

  10. LAB building a home for scientists

    Fishman, Mark C

    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.

    Rossi, Bruno

    1990-08-01

    Bruno Rossi has long been an influential figure in diverse areas of physics and in this volume he presents a fascinating account of his life and work as an experimental physicist. 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.

    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.

    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.

  17. 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...

  18. The challenges for scientists in avoiding plagiarism.

    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.

    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.

  1. 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.

  2. The Maturation of a Scientist: An Autobiography.

    Roizman, Bernard

    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.

    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.

  4. 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.

  5. An example of woman scientist in France

    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.

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

    Science.gov (United States)

    Harding, Clifford V; Akabas, Myles H; Andersen, Olaf S

    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.

  9. Scientists' perspectives on the ethical issues of stem cell research.

    2009-06-01

    This paper describes findings from an ethics education project funded by the Canadian Stem Cell Network (SCN). The project is part of a larger research initiative entitled "The Stem Cell Research Environment: Drawing the Evidence and Experience Together". The ethics education study began with a series of focus groups with SCN researchers and trainees as part of a "needs assessment" effort. The purpose of these discussions was to identify the main ethical issues associated with stem cell (SC) research from the perspective of the stem cell community. This paper will focus on five prominent themes that emerged from the focus group data including: (1) the source of stem cells; (2) the power of stem cells; (3) working within a charged research environment; (4) the regulatory context; and (5) ethics training for scientists. Additional discussions are planned with others involved in Canadian stem cell research (e.g., research ethics board members, policy makers) to supplement initial findings. These assessment results combined with existing bioethics literature will ultimately inform a web-based ethics education module for the SCN. We believe that our efforts are important for those analyzing the ethical, legal, and social issues (ELSI) in this area because our in depth understanding of stem cell researcher perspectives will enable us to develop more relevant and effective education material, which in turn should help SC researchers address the important ethical challenges in their area.

    In September 2011, the Cassini spacecraft took images of three targets and a challenge was launched to all students: to choose the one target they thought would provide the best science and to write an essay explaining their reasons (more information on the "Cassini Scientist for a Day" essay contest official webpage in: http://saturn.jpl.nasa.gov/education/scientistforaday10thedition/, run by NASA/JPL) The three targets presented were: Hyperion, Rhea and Titan, and Saturn. The idea behind "Cassini Scientist for a Day: a tactile experience" was to transform each of these images into schematic tactile images, highlighting relevant features apprehended through a tactile key, accompanied by a small text in Braille with some additional information. This initial approach would allow reach a broader community of students, more specifically those with visual impairment disabilities. Through proper implementation and careful study cases the adapted images associated with an explanatory key provide more resources in tactile astronomy. As the 2012 edition approaches a new set of targeted objet images will be once again transformed and adapted to visually impaired students and will aim to reach more students into participate in this international competition and to engage them in a quest to expand their knowledge in the amazing Cassini discoveries and the wonders of Saturn and its moons. As the winning essays will be published on the Cassini website and contest winners invited to participate in a dedicated teleconference with Cassini scientists from NASA's Jet Propulsion Laboratory, this initiative presents a great chance to all visually impaired students and teachers to participate in an exciting experience. These initiatives must be complemented with further information to strengthen the learning experience. However they stand as a good starting point to tackle further astronomical concepts in the classroom, especially this field that sometimes lacks the resources. Although

    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.

    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

    The Young Earth System Scientists (YESS) community is compiled of early career researchers (including students) coming from a range of scientific backgrounds, spanning both natural and social sciences. YESS unifies young researchers in an influential network to give them a collective voice and leverage within the geosciences community, while supporting career development. The YESS community has used its powerful network to provide a unified perspective on the future of Earth system science (Rauser et al. 2017), to be involved in the organization of international conferences, and to engage with existing international structures that coordinate science. Since its founding in Germany in 2010, the YESS community has grown extensively across the globe, with currently almost 1000 members from over 80 countries, and has become truly interdisciplinary. Recently, the organization has carried elections for Regional Representatives and the Executive Committee as part of its self-sustained governance structure. YESS is ready to continue pioneering crucial areas of research which provide solutions to benefit society for the long-term advancement of Earth system science.

  16. Collaboration and Gender Equity among Academic Scientists

    Full Text Available Universities were established as hierarchical bureaucracies that reward individual attainment in evaluating success. Yet collaboration is crucial both to 21st century science and, we argue, to advancing equity for women academic scientists. We draw from research on gender equity and on collaboration in higher education, and report on data collected on one campus. Sixteen focus group meetings were held with 85 faculty members from STEM departments, separated by faculty rank and gender (i.e., assistant professor men, full professor women. Participants were asked structured questions about the role of collaboration in research, career development, and departmental decision-making. Inductive analyses of focus group data led to the development of a theoretical model in which resources, recognition, and relationships create conditions under which collaboration is likely to produce more gender equitable outcomes for STEM faculty. Ensuring women faculty have equal access to resources is central to safeguarding their success; relationships, including mutual mentoring, inclusion and collegiality, facilitate women’s careers in academia; and recognition of collaborative work bolsters women’s professional advancement. We further propose that gender equity will be stronger in STEM where resources, relationships, and recognition intersect—having multiplicative rather than additive effects.

  17. The first scientist Anaximander and his legacy

    Carlo Rovelli, a leading theoretical physicist, uses the figure of Anaximander as the starting point for an examination of scientific thinking itself: its limits, its strengths, its benefits to humankind, and its controversial relationship with religion. Anaximander, the sixth-century BC Greek philosopher, is often called the first scientist because he was the first to explain that order in the world was due to natural forces, not supernatural ones. He is the first person known to rnunderstand that the Earth floats in space; to believe that the sun, the moon, and the stars rotate around it--seven centuries before Ptolemy; to argue that all animals came from the sea and evolved; and to posit that universal laws rncontrol all change in the world. Anaximander taught Pythagoras, who would build on Anaximander's scientific theories by applying mathematical laws to natural phenomena. rnrnIn the award-winning Anaximander and the Birth of Scientific Thought, Rovelli restores Anaximander to his place in the history of...

    Lepidopterists use substantial volumes of solvents, such as chloroform, 1,1,2,2-tetrachloroethane and xylene, in their traps when collecting faunistic and phenological data. A majority of them are citizen scientists and thus in part not identified by occupational healthcare as being at risk due to solvent handling. We surveyed the extent of solvent use, the frequency and extent of potential exposure and the safety precautions taken in trapping and catch handling by Finnish lepidopterists. Chloroform and 1,1,2,2-tetrachloroethane were the most frequently used anaesthetics. Potential for exposure prevailed during trap maintenance and exploration and catch sorting. Adequate protection against vapours or spills was worn by 17% during trap exploration. Subjects completed a median of 100 trap explorations per season. Dermal or mucosal spills were recorded at a median rate of one spill per ten (chloroform) to 20 (1,1,2,2-tetrachloroethane and xylene) trap explorations. Median annual cumulative durations of 8 and 20 h of exposure to chloroform and 1,1,2,2-tetrachloroethane at levels above odour detection threshold were reported. Subjective adverse findings possibly related solvents had been noticed by 24 (9.8%) lepidopterists. All the events had been mild to moderate. No factor predicting unsafe procedures or adverse reactions was recorded despite thorough statistical testing. Copyright © 2016 Elsevier Ltd. All rights reserved.

  19. Stephen C. Woods: a precocious scientist.

    Smith, Gerard P

    2011-04-18

    To investigate the early scientific development of Steve Woods, I reviewed his research during the first decade after he received his doctoral degree in 1970. The main parts of his research program were conditioned insulin secretion and hypoglycemia, Pavlovian conditioning of insulin secretion before a scheduled access to food, and basal insulin as a negative-feedback signal from fat mass to the brain. These topics were pursued with experimental ingenuity; the resulting publications were interesting, clear, and rhetorically effective. Although the theoretical framework for his experiments with insulin was homeostatic, by the end of the decade he suggested that classic negative-feedback homeostasis needed to be revised to include learning acquired by lifestyle. Thus, Woods functioned as a mature scientist from the beginning of his research-he was very precocious. This precocity also characterized his teaching and mentoring as recalled by two of his students during that time, Joseph Vasselli and Paul Kulkosky. The most unusual and exemplary aspect of his precocity is that the outstanding performance of his first decade was maintained during the subsequent 30years. Copyright © 2011 Elsevier Inc.

    Results are presented from a survey held among 1868 scientists studying various aspects of climate change, including physical climate, climate impacts, and mitigation. The survey was unique in its size, broadness and level of detail. Consistent with other research, we found that, as the level of expertise in climate science grew, so too did the level of agreement on anthropogenic causation. 90% of respondents with more than 10 climate-related peer-reviewed publications (about half of all respondents), explicitly agreed with anthropogenic greenhouse gases (GHGs) being the dominant driver of recent global warming. The respondents' quantitative estimate of the GHG contribution appeared to strongly depend on their judgment or knowledge of the cooling effect of aerosols. The phrasing of the IPCC attribution statement in its fourth assessment report (AR4)-providing a lower limit for the isolated GHG contribution-may have led to an underestimation of the GHG influence on recent warming. The phrasing was improved in AR5. We also report on the respondents' views on other factors contributing to global warming; of these Land Use and Land Cover Change (LULCC) was considered the most important. Respondents who characterized human influence on climate as insignificant, reported having had the most frequent media coverage regarding their views on climate change.

    ASPERA Press Release

    2011-01-01

    Plans shape up for a revolutionary new observatory that will explore black holes and the Big Bang. This detector will ‘see’ the Universe in gravitational waves.   A new era in astronomy will come a step closer when scientists from across Europe present their design study today for an advanced observatory capable of making precision measurements of gravitational waves – minute ripples in the fabric of spacetime – predicted to emanate from cosmic catastrophes such as merging black holes and collapsing stars and supernovae. It also offers the potential to probe the earliest moments of the Universe just after the Big Bang, which are currently inaccessible. The Einstein Observatory (ET) is a so-called third-generation gravitational-wave (GW) detector, which will be 100 times more sensitive than current instruments. Like the first two generations of GW detectors, it is based on the measurement of tiny changes (far less than the size of an atomic nucleus) in the le...

    2002-01-01

    This study examined the perceptions and self-reported practices of 18 scientists participating in a yearlong seminar series designed to explore issues of gender and ethnicity in science. Scientists and seminar were part of the Promoting Women and Scientific Literacy project, a curriculum transformation and professional development initiative undertaken by science, science education, and women's studies faculty at their university. Researchers treated participating scientists as critical friends able to bring clarity to and raise questions about conceptions of inclusion in science education. Through questionnaires and semistructured interviews, we explored their (a) rationales for differential student success in undergraduate science education; (b) self-reports of ways they structure, teach, and assess courses to promote inclusion; and (c) views of androcentric and ethnocentric bias in science. Statistical analysis of questionnaires yielded few differences in scientists' views and reported practices by sex or across time. Qualitative analysis of interviews offered insight into how scientists can help address the problem of women and ethnic minorities in science education; constraints encountered in attempts to implement pedagogical and curricular innovations; and areas of consensus and debate across scientists and science studies scholars' descriptions of science. From our findings, we provided recommendations for other professional developers working with scientists to promote excellence and equity in undergraduate science education.

    There is paucity of physician-scientists in Africa, resulting in overt dependence of clinical practice on research findings from advanced "first world" countries. Physician-scientists include individuals with a medical degree alone or combined with other advanced degrees (e.g. MD/MBChB and PhD) with a career path in biomedical/ translational and patient-oriented/evaluative science research. The paucity of clinically trained research scientists in Africa could result in dire consequences as exemplified in the recent Ebola virus epidemic in West Africa, where shortage of skilled clinical scientists, played a major role in disease progression and mortality. Here we contextualise the role of physician-scientist in health care management, highlight factors limiting the training of physician-scientist in Africa and proffer implementable recommendations to address these factors.

  4. Scientists' Prioritization of Communication Objectives for Public Engagement.

    Directory of Open Access Journals (Sweden)

    Anthony Dudo

    Full Text Available Amid calls from scientific leaders for their colleagues to become more effective public communicators, this study examines the objectives that scientists' report drive their public engagement behaviors. We explore how scientists evaluate five specific communication objectives, which include informing the public about science, exciting the public about science, strengthening the public's trust in science, tailoring messages about science, and defending science from misinformation. We use insights from extant research, the theory of planned behavior, and procedural justice theory to identify likely predictors of scientists' views about these communication objectives. Results show that scientists most prioritize communication designed to defend science from misinformation and educate the public about science, and least prioritize communication that seeks to build trust and establish resonance with the public. Regression analyses reveal factors associated with scientists who prioritize each of the five specific communication objectives. Our findings highlight the need for communication trainers to help scientists select specific communication objectives for particular contexts and audiences.

    Scientists are required to communicate science and research not only to other experts in the field, but also to scientists and experts from other fields, as well as to the public and policymakers. One fundamental suggestion when communicating with non-experts is to avoid professional jargon. However, because they are trained to speak with highly specialized language, avoiding jargon is difficult for scientists, and there is no standard to guide scientists in adjusting their messages. In this research project, we present the development and validation of the data produced by an up-to-date, scientist-friendly program for identifying jargon in popular written texts, based on a corpus of over 90 million words published in the BBC site during the years 2012–2015. The validation of results by the jargon identifier, the De-jargonizer, involved three mini studies: (1) comparison and correlation with existing frequency word lists in the literature; (2) a comparison with previous research on spoken language jargon use in TED transcripts of non-science lectures, TED transcripts of science lectures and transcripts of academic science lectures; and (3) a test of 5,000 pairs of published research abstracts and lay reader summaries describing the same article from the journals PLOS Computational Biology and PLOS Genetics. Validation procedures showed that the data classification of the De-jargonizer significantly correlates with existing frequency word lists, replicates similar jargon differences in previous studies on scientific versus general lectures, and identifies significant differences in jargon use between abstracts and lay summaries. As expected, more jargon was found in the academic abstracts than lay summaries; however, the percentage of jargon in the lay summaries exceeded the amount recommended for the public to understand the text. Thus, the De-jargonizer can help scientists identify problematic jargon when communicating science to non-experts, and be implemented

    For the past 16 years, the International Training and Research in Environmental and Occupational Health program (ITREOH) has supported projects that link U.S. academic scientists with scientists from low- and middle-income countries in diverse research and research training activities. Twenty-two projects of varied duration have conducted training to enhance the research capabilities of scientists at 75 institutions in 43 countries in Asia, Africa, Eastern Europe, and Latin America, and have built productive research relationships between these scientists and their U.S. partners. ITREOH investigators and their trainees have produced publications that have advanced basic sciences, developed methods, informed policy outcomes, and built institutional capacity. Today, the changing nature of the health sciences calls for a more strategic approach. Data-rich team science requires greater capacity for information technology and knowledge synthesis at the local institution. More robust systems for ethical review and administrative support are necessary to advance population-based research. Sustainability of institutional research capability depends on linkages to multiple national and international partners. In this context, the Fogarty International Center, the National Institute of Environmental Sciences and the National Institute for Occupational Safety and Health, have reengineered the ITREOH program to support and catalyze a multi-national network of regional hubs for Global Environmental and Occupational Health Sciences (GEOHealth). We anticipate that these networked science hubs will build upon previous investments by the ITREOH program and will serve to advance locally and internationally important health science, train and attract first-class scientists, and provide critical evidence to guide policy discussions.

    2008-12-01

    Innovative approaches to science education are critical for inspiring a new generation of scientists. In a world where students are inundated with digital media inviting them to explore exciting, emerging disciplines, science often lags behind in using progressive media techniques. Additionally, science education media often neglects to include the scientists conducting research, thereby disconnecting students from the excitement, adventure, and beauty of conducting research in the field. Here we present initial work from a science education media project entitled Canopy in the Clouds. In particular, we address the goals and approach of the project, the logistics associated with generating educational material at a foreign field site, and the challenges associated with effectively integrating science and media. Canopy in the Clouds is designed to engage students in research, motivate a new generation of young scientists, and promote conservation from the perspective of a current research project being conducted in the canopy of a tropical montane cloud forest located in Monteverde, Costa Rica. The project seeks to generate curriculum based on multiple, immersive forms of novel digital media that attract and maintain student attention. By doing so from the perspective of an adventurous research project in a beautiful and highly biodiverse region, we hope to engage students in science and enhance bioliteracy. However, there are considerable logistic considerations associated with such an approach, including safety, travel, permitting, and equipment maintenance. Additionally, the goals of both the scientific research and the educational media project must be balanced in order to meet objectives in a timely fashion. Finally, materials generated in the field must be translated to viable final products and distributed. Work associated with Canopy in the Clouds will thus provide insight into this process and can serve to inform future science education and outreach

The YES program provides talented high school juniors and seniors a bridge between classroom instruction and real world, research experiences in physical sciences (including space science) and engineering. The first component of YES is an intensive three-week summer workshop held at SwRI where students experience the research environment first-hand; develop skills and acquire tools for solving scientific problems, attend mini-courses and seminars on electronics, computers and the Internet, careers, science ethics, and other topics; and select individual research projects to be completed during the academic year. Afterwards, students complete individual research projects under the guidance of their mentors during the academic year and earn honors credit. At the end of the school year, students publicly present and display their work, acknowledging their accomplishments and spreading career awareness to other students and teachers. During these years, YES has developed a website for topics in space science from the perspective of high school students, including NASA's Magnetospheric Multiscale Mission (MMS) (http://yesserver.space.swri.edu). High school science teachers participate in the workshop and develop space-related lessons for classroom presentation in the academic year. Student evaluations indicate the effectiveness of YES on their academic preparation and choice of college majors. Over the past 16 years, all YES graduates have entered college, several have worked for SwRI, one business has started, and three scientific publications have resulted. Acknowledgements.

    Recently, Italian newspapers reported the statements of Japanese and American volcanologists which declared the high hazard related to the future occurrence of catastrophic eruption at Vesuvius. Is this a reliable picture from scientific point of view? The evaluation of volcanic hazard is based on a general statistical law for which the chances of an eruptive event increase when energy decreases. This law is constructed on the basis of empirical data. Thus, the possibility that a plinian-like eruption occurs, for each volcano, is rare and further reduced for worst-case scenario. However, empirical data are not supported by a robust scientific theory, experimentally verifiable through an exact forecast of a long-term eruption, both in time limits and in energy. Today, the lack of paradigms able to predict in a deterministic way such a complex phenomena, limit the field of the scientists that cannot go further evaluations of a purely probabilistic nature. From this point of view volcanology cannot be considered an hard quantitative Science. The declaration according to which Vesuvius, sooner or later, will produce a catastrophic eruption, yet apparently obvious if we consider the very high degree of urbanization, is not supported by any experimentally verifiable theory. Therefore, the statement according to which Vesuvius next eruptive event will be catastrophic is false. In probabilistic terms, it is actually the least possible scenario. Recognizing the cognitive limits in this research field means to encourage research itself towards the determination of more solid paradigms, in order to get more exact forecasts about such complex phenomena. The scientific compromise of defining risk scenarios, rather than deterministic evaluations about future eruptive events, precisely reflects the limits of research that have to be contemplated even by Civil Protection. Having considered these limits, every risk scenario, even the most conservative, will be ineffective in

    , subscriptions do not provide access to the full range of HIV vaccine research literature. Access to papers through subscriptions is complemented by a variety of other means, including emailing corresponding authors, joint affiliations, use of someone else's login information and posting requests on message boards. This complex picture makes it difficult to assess the real ability of scientists to access literature, but the observed differences in access levels between institutions suggest an unlevel playing field, in which some researchers have to spend more efforts than others to obtain the same information.

  1. One Model for Scientist Involvement in K-12 Education: Teachers Experiencing Antarctica and the Arctic Program

    Scientists involved in the NSF-funded Teachers Experiencing Antarctica and the Arctic (TEA) Program integrate a K-12 science teacher into their polar field project. Objectives of the program include: having the science teacher immersed in the experience of research; 2) through the teacher, leveraging the research experience to better inform teaching practices; and 3) sharing the experience with the broader educational and general community. The scientist - or qualified team member - stays involved with the teacher throughout the program as a mentor. Preparation of the teacher involves a week-long orientation presented by the TEA Program, and a two week pre-expedition visit at the scientist's institution. Orientation acquaints teachers with program expectations, logistical information, and an overview of polar science. While at the scientist's institution, the teacher meets the team, prepares for the field, and strengthens content knowledge. In the field, the teacher is a team member and educational liaison, responding to questions from students and colleagues by e-mail, and posting electronic journals describing the research experience. Upon return, the teachers work closely with colleagues to bring the experience of research into classrooms through creation of activities, design of longer-term student investigations, and presentations at scientific, educational, and community meetings. Interaction with the scientific team continues with a visit by the scientist to the teacher's classrooms, collaboration on presentations at scientific meetings, and consultation on classroom activities. In some cases, the teacher may participate in future expeditions. The involvement by scientists in mentor relationships, such as those of the TEA Program, is critical to improving science education. Many teachers of science have not had the opportunity to participate in field research, which offers valuable first-hand experience about the nature of science, as well as about specific

    Social network analysis (SNA) is becoming increasingly concerned not only with actors and their relations, but also with distinguishing between different types of such entities. For example, social scientists may want to investigate asymmetric relations in organizations with strict chains of command, or incorporate non-actors such as conferences and projects when analyzing coauthorship patterns. Multimodal social networks are those where actors and relations belong to different types, or modes, and multimodal social network analysis (mSNA) is accordingly SNA for such networks. In this paper, we present a design study that we conducted with several social scientist collaborators on how to support mSNA using visual analytics tools. Based on an openended, formative design process, we devised a visual representation called parallel node-link bands (PNLBs) that splits modes into separate bands and renders connections between adjacent ones, similar to the list view in Jigsaw. We then used the tool in a qualitative evaluation involving five social scientists whose feedback informed a second design phase that incorporated additional network metrics. Finally, we conducted a second qualitative evaluation with our social scientist collaborators that provided further insights on the utility of the PNLBs representation and the potential of visual analytics for mSNA.

  11. Thinking like a scientist: innateness as a case study.

    2013-01-01

    The concept of innateness appears in systematic research within cognitive science, but it also appears in less systematic modes of thought that long predate the scientific study of the mind. The present studies therefore explore the relationship between the properly scientific uses of this concept and its role in ordinary folk understanding. Studies 1-4 examined the judgments of people with no specific training in cognitive science. Results showed (a) that judgments about whether a trait was innate were not affected by whether or not the trait was learned, but (b) such judgments were impacted by moral considerations. Study 5 looked at the judgments of both non-scientists and scientists, in conditions that encouraged either thinking about individual cases or thinking about certain general principles. In the case-based condition, both non-scientists and scientists showed an impact of moral considerations but little impact of learning. In the principled condition, both non-scientists and scientists showed an impact of learning but little impact of moral considerations. These results suggest that both non-scientists and scientists are drawn to a conception of innateness that differs from the one at work in contemporary scientific research but that they are also both capable of 'filtering out' their initial intuitions and using a more scientific approach.

    Full Text Available Since 2010, the Italian Ministry of University and Research issued new evaluation protocols to select candidates for University professorships and assess the bibliometric productivity of Universities and Research Institutes based on bibliometric indicators, i.e. scientific paper and citation numbers and the h-index. Under this framework, the objective of this study was to quantify the bibliometric productivity of the Italian forest research community during the 2002-2012 period. We examined the following productivity parameters: (i the bibliometric productivity under the Forestry subject category at the global level; (ii compared the aggregated bibliometric productivity of Italian forest scientists with scientists from other countries; (iii analyzed publication and citation temporal trends of Italian forest scientists and their international collaborations; and (iv characterized productivity distribution among Italian forest scientists at different career levels. Results indicated the following: (i the UK is the most efficient country based on the ratio between Gross Domestic Spending (GDS on Research and Development (R&D and bibliometric productivity under the Forestry subject category, followed by Italy; (ii Italian forest scientist productivity exhibited a significant positive time trend, but was characterized by high inequality across authors; (iii one-half of the Italian forest scientist publications were written in collaboration with foreign scientists; (iv a strong relationship exists between bibliometric indicators calculated by WOS and SCOPUS, suggesting these two databases have the same potential to evaluate the forestry research community; and (v self-citations did not significantly affect the rank of Italian forest scientists.

  19. Relations between scientists and government: the case of nuclear energy

    Energy Technology Data Exchange (ETDEWEB)

    Katz, J E

    1982-05-01

    This article discusses the role and influence of the scientific communities in less-developed countries (LDC) on national high-technology policy by examining the particular case of nuclear energy. This area has been largely overlooked by other literature on LDC's scientific development. Based on an examination of scientific involvement in nuclear energy policy in selected countries, it becomes clear that the influence of scientists can range from making cardinal decisions about programs to simply legitimating or implementing decisions made by political or bureaucratic leaders. Within governmental structures, there are opportunities for scientists to incrementally shape technology policies, despite the fact that the magnitude of this influence is circumscribed by domestic considerations, not only of physical resources, but also intangibles such as national prestige and security. While a scientist can on rare occasion seize opportunities to dramatically restructure a nation's scientific or nuclear program, the overwhelming majority of scientists never exercise any such power. But even in day-to-day operations of government scientists can exert subtle influence, not only on nuclear energy programs, but also in an indirect way on the fabric of a nation's culture. Despite this significant impact, in any direct contest between the scientist and the politician, the scientist inevitably loses. In conclusion, scientists seem much more aware of their limitations rather than their potential to influence national technology policy, and tend to act in accord with priorities and goals as defined by their nation-state. 18 references.

    This article intends to convey the improvement regarding the knowledge exchange in the astronomical field through an improvement in the quality of professional communication between researchers, teachers and the like whose job is to broadcast astronomical concepts. It has been a couple of years since the difficulty of communicating astronomical concepts decreased due to institutional projects, schools and education systems. Inside the education system, the need to include astronomy as an innovative element in curricula has become obvious. Outside, an informal public interested in astronomy became greater in number and began to be fostered by different organizations which spread their astronomical knowledge via workshops and demonstrations.

  4. Overcoming the obstacles: Life stories of scientists with learning disabilities

    Science.gov (United States)

    Force, Crista Marie

    Scientific discovery is at the heart of solving many of the problems facing contemporary society. Scientists are retiring at rates that exceed the numbers of new scientists. Unfortunately, scientific careers still appear to be outside the reach of most individuals with learning disabilities. The purpose of this research was to better understand the methods by which successful learning disabled scientists have overcome the barriers and challenges associated with their learning disabilities in their preparation and performance as scientists. This narrative inquiry involved the researcher writing the life stories of four scientists. These life stories were generated from extensive interviews in which each of the scientists recounted their life histories. The researcher used narrative analysis to "make sense" of these learning disabled scientists' life stories. The narrative analysis required the researcher to identify and describe emergent themes characterizing each scientist's life. A cross-case analysis was then performed to uncover commonalities and differences in the lives of these four individuals. Results of the cross-case analysis revealed that all four scientists had a passion for science that emerged at an early age, which, with strong drive and determination, drove these individuals to succeed in spite of the many obstacles arising from their learning disabilities. The analysis also revealed that these scientists chose careers based on their strengths; they actively sought mentors to guide them in their preparation as scientists; and they developed coping techniques to overcome difficulties and succeed. The cross-case analysis also revealed differences in the degree to which each scientist accepted his or her learning disability. While some demonstrated inferior feelings about their successes as scientists, still other individuals revealed feelings of having superior abilities in areas such as visualization and working with people. These individuals revealed

    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. © 2016 J.

Most scientists on military work were and are not only justifying their work, but they are enjoying their lives. A general strike of the military scientists against the arms race is an illusion. A pragmatic approach to the problem is need. In any case it is imperative that concerned scientists concentrate on the struggle against the threat of nuclear war. They must interact with the people at large, especially the people in the mass organizations, and help them to judge the situation and to evolve suitable countermeasures. A few words are said about the possibility of world government. (author)

  14. Reciprocal Engagement Between a Scientist and Visual Displays

    Science.gov (United States)

    Nolasco, Michelle Maria

    In this study the focus of investigation was the reciprocal engagement between a professional scientist and the visual displays with which he interacted. Visual displays are considered inextricable from everyday scientific endeavors and their interpretation requires a "back-and-forthness" between the viewers and the objects being viewed. The query that drove this study was: How does a scientist engage with visual displays during the explanation of his understanding of extremely small biological objects? The conceptual framework was based in embodiment where the scientist's talk, gesture, and body position were observed and microanalyzed. The data consisted of open-ended interviews that positioned the scientist to interact with visual displays when he explained the structure and function of different sub-cellular features. Upon microanalyzing the scientist's talk, gesture, and body position during his interactions with two different visual displays, four themes were uncovered: Naming, Layering, Categorizing, and Scaling . Naming occurred when the scientist added markings to a pre-existing, hand-drawn visual display. The markings had meaning as stand-alone label and iconic symbols. Also, the markings transformed the pre-existing visual display, which resulted in its function as a new visual object. Layering occurred when the scientist gestured over images so that his gestures aligned with one or more of the image's features, but did not touch the actual visual display. Categorizing occurred when the scientist used contrasting categories, e.g. straight vs. not straight, to explain his understanding about different characteristics that the small biological objects held. Scaling occurred when the scientist used gesture to resize an image's features so that they fit his bodily scale. Three main points were drawn from this study. First, the scientist employed a variety of embodied strategies—coordinated talk, gesture, and body position—when he explained the structure

    2011-12-01

    The Science Teacher Education Program (STEP) offered a unique framework for creating professional development courses focused on Arctic research from 2006-2009. Under the STEP framework, science, technology, engineering, and math (STEM) training was delivered by teams of practicing Arctic researchers in partnership with master teachers with 20+ years experience teaching STEM content in K-12 classrooms. Courses based on the framework were offered to educators across Alaska. STEP offered in-person summer-intensive institutes and follow-on audio-conferenced field-test courses during the academic year, supplemented by online scientist mentorship for teachers. During STEP courses, teams of scientists offered in-depth STEM content instruction at the graduate level for teachers of all grade levels. STEP graduate-level training culminated in the translation of information and data learned from Arctic scientists into standard-aligned lessons designed for immediate use in K-12 classrooms. This presentation will focus on research that explored the question: To what degree was scientist involvement beneficial to teacher training and to what degree was STEP scientist involvement beneficial to scientist instructors? Data sources reveal consistently high levels of ongoing (4 year) scientist and teacher participation; high STEM content learning outcomes for teachers; high STEM content learning outcomes for students; high ratings of STEP courses by scientists and teachers; and a discussion of the reasons scientists indicate they benefited from STEP involvement. Analyses of open-ended comments by teachers and scientists support and clarify these findings. A grounded theory approach was used to analyze teacher and scientist qualitative feedback. Comments were coded and patterns analyzed in three databases. The vast majority of teacher open-ended comments indicate that STEP involvement improved K-12 STEM classroom instruction, and the vast majority of scientist open-ended comments

    Young scientists in nearly every field are finding the job market of the 1990's a confusing and frustrating place. Ph.D. supply is far larger than that needed to fill entry-level positions in "traditional" research careers. More new Ph.D. and Master's degree holders are considering a wider range of careers in and out of science, but feel ill-prepared and uninformed about their options. Some feel their Ph.D. training has led them to a dead-end. I present a thorough and practical overview to the process of career planning and job hunting in the 1990's, from the perspective of a young scientist. I cover specific steps that young scientists can take to broaden their horizons, strengthen their skills, and present their best face to potential employers. An important part of this is the realization that most young scientists possess a range of valuable "transferable skills" that are highly sought after by employers in and out of science. I will summarize the specifics of job hunting in the 90's, including informational interviewing, building your network, developing a compelling CV and resume, cover letters, interviewing, based on my book "To Boldly Go: A Practical Career Guide for Scientists". I will also identify other resources available for young scientists. Finally, I will highlight individual stories of Ph.D.-trained scientists who have found exciting and fulfilling careers outside the "traditional" world of academia.

  17. Scientists as role models in space science outreach

    Alexander, D.

    The direct participation of scientists significantly enhances the impact of any E/PO effort. This is particularly true when the scientists come from minority or traditionally under-represented groups and, consequently, become role models for a large number of students while presenting positive counter-examples to the usual stereotypes. In this paper I will discuss the impact of scientists as role models through the successful implementation of a set of space physics games and activities, called Solar Week. Targetted at middle-school girls, the key feature of Solar Week is the "Ask a Scientist" section enabling direct interaction between participating students and volunteer scientists. All of the contributing scientists are women, serving as experts in their field and providing role models to whom the students can relate. Solar Week has completed four sessions with a total of some 140 edcuators and 12,000+ students in over 28 states and 9 countries. A major success of the Solar Week program has been the ability of the students to learn more about the scientists as people, through online biographies, and to discuss a variety of topics ranging from science, to careers and common hobbies.

    Most bioethics studies have focused on capturing the views of patients and the general public on research ethics issues related to informed consent for biobanking and only a handful of studies have examined the perceptions of scientists. Capturing the opinions of scientists is important because they are intimately involved with biobanks as collectors and users of samples and health information. In this study, we performed interviews with scientists followed by qualitative analysis to capture the diversity of perspectives on informed consent. We found that the majority of scientists in our study reported their preference for a general consent approach although they do not believe there to be a consensus on consent type. Despite their overall desire for a general consent model, many reported several concerns including donors needing some form of assurance that nothing unethical will be done with their samples and information. Finally, scientists reported mixed opinions about incorporating exclusion clauses in informed consent as a means of limiting some types of contentious research as a mechanism to assure donors that their samples and information are being handled appropriately. This study is one of the first to capture the views of scientists on informed consent in biobanking. Future studies should attempt to generalize findings on the perspectives of different scientists on informed consent for biobanking.

    Atmospheric Science Collaborations and Enriching NeTworks (ASCENT) is a workshop series designed to bring together early career female scientists in the field of atmospheric science and related disciplines. ASCENT is a multi-faceted approach to retaining these junior scientists through the challenges in their research and teaching career paths. During the workshop, senior women scientists discuss their career and life paths. They also lead seminars on tools, resources and methods that can help early career scientists to be successful. Networking is a significant aspect of ASCENT, and many opportunities for both formal and informal interactions among the participants (of both personal and professional nature) are blended in the schedule. The workshops are held in Steamboat Springs, Colorado, home of a high-altitude atmospheric science laboratory - Storm Peak Laboratory, which also allows for nearby casual outings and a pleasant environment for participants. Near the conclusion of each workshop, junior and senior scientists are matched in mentee-mentor ratios of two junior scientists per senior scientist. An external evaluation of the three workshop cohorts concludes that the workshops have been successful in establishing and expanding personal and research-related networks, and that seminars have been useful in creating confidence and sharing resources for such things as preparing promotion and tenure packages, interviewing and negotiating job offers, and writing successful grant proposals.

  20. Reducing Flood Impacts for Wellbeing of Arctic Communities through Collaboration among Community and Tribal Leaders, Scientists, and Emergency Man

    2016-12-01

    In Alaska and the Sakha Republic (Siberia), multiple communities are exposed to flooding every spring. A bilateral and multidisciplinary team was established, as part of the U.S. State Department FY2015-16 U.S.-Russia Peer-to-Peer Dialogue Initiative, to conduct the project Reducing Spring Flood Impacts for Wellbeing of Communities of the North. The project comprised community-based participatory research, education, and cultural activities that used flood sites in Alaska and Siberia as case studies. A diverse and bilateral team (community leaders, scientists, students, and emergency managers) was established to share experiences and identify best practices in mitigating the risk of and improving response to floods.This science-community collaboration has inspired a dialogue between present and future decision makers and community residents. Preliminary analysis revealed that community members in both regions are interested in collaborations with scientists to reduce flood risks and impacts. They are eager to share their experiences. However, scientists have to earn the trust of and develop a rapport with local leaders beforehand. Conflicts arise when communities perceive scientists as governmental representatives due to the fact that most scientific funds come from federal and state grants. Scientists are also held responsible for disasters, due to their roles in disaster forecasting and warnings. In both regions, impacted populations often blame the government for flood impacts; not unreasonably. Originally nomadic, native populations were forced to settle in floodplains by governments. Now, exposed to floods, they regard damage reimbursement as a predominantly governmental responsibility. Scientists can offer long-term solutions that would benefit communities at risk and governmental entities. However, it is important for scientists not to impose solutions, but instead initiate and maintain a dialogue about alternatives, especially as sensitive as relocation.

  1. Scientist-Teacher Partnerships as Professional Development: An Action Research Study

    2009-04-01

    The overall purpose of this action research study was to explore the experiences of ten middle school science teachers involved in a three-year partnership program between scientists and teachers at a Department of Energy national laboratory, including the impact of the program on their professional development, and to improve the partnership program by developing a set of recommendations based on the study’s findings. This action research study relied on qualitative data including field notes recorded at the summer academies and data from two focus groups with teachers and scientists. Additionally, the participating teachers submitted written reflections in science notebooks, participated in open-ended telephone interviews that were transcribed verbatim, and wrote journal summaries to the Department of Energy at the end of the summer academy. The analysis of the data, collaboratively examined by the teachers, the scientists, and the science education specialist acting as co-researchers on the project, revealed five elements critical to the success of the professional development of science teachers. First, scientist-teacher partnerships are a unique contribution to the professional development of teachers of science that is not replicated in other forms of teacher training. Second, the role of the science education specialist as a bridge between the scientists and teachers is a unique and vital one, impacting all aspects of the professional development. Third, there is a paradox for classroom teachers as they view the professional development experience from two different lenses – that of learner and that of teacher. Fourth, learning for science teachers must be designed to be constructivist in nature. Fifth, the principles of the nature of science must be explicitly showcased to be seen and understood by the classroom teacher.

    This research examines the nature of disagreements between natural and social scientists during discussions of global climate change. In particular, it explores whether the disagreements between natural and social scientists are related to the ontological, epistemological, or methodological nature of the uncertainty of global climate change during these discussions. A purposeful sample of 30 natural and social scientists recognized as experts in global climate change by the United States Global Change Research Program (USGCRP) and National Academies Committee on Global Change were interviewed to elicit their perceptions of disagreements during their three most troublesome discussions on global climate change. A mixed-method (qualitative plus quantitative research) approach with three independent variables was used to explore nature of uncertainty as a mediating variable in the relationships between academic training, level of sureness, level of knowledge, and position on global climate change, and the nature of disagreements and bridging strategies of natural and social scientists (Patton, 1997; Frechtling et al., 1997). This dissertation posits that it is the differences in the nature of uncertainty communicated by natural and social scientists and not sureness, knowledge, and position on global climate change that causes disagreements between the groups. By describing the nature of disagreements between natural and social scientists and illuminating bridging techniques scientists use during these disagreements, it is hoped that information collected from this research will create a better dialogue between the scientists studying global climate change by providing communication strategies which will allow those versed in one particular area to speak to non-experts whether they be other scientists, media officials, or the public. These tangible strategies can then be used by government agencies to create better communications and education plans, which can

    2005-03-01

    On 2 January 1995 Martin Stutzmann became Editor-in-Chief of physica status solidi, replacing Professor E. Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from socialism as found in the real world (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal.Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality

    We report the changes that have taken place recently regarding the situation of female scientists in Argentina. We comment on the rules for maternity leave that have been passed recently for research scholars doing their PhDs and on the number of women scientists that occupy decision making-positions in science. We also present some evidence that seems to indicate that, among young scientists, women are more willing to occupy leadership positions and that the Argentinean society is more accepting of this new role.

    Comparing and contrasting the reality of subjectivity in the work of history's great scientists and the modern Bayesian approach to statistical analysisScientists and researchers are taught to analyze their data from an objective point of view, allowing the data to speak for themselves rather than assigning them meaning based on expectations or opinions. But scientists have never behaved fully objectively. Throughout history, some of our greatest scientific minds have relied on intuition, hunches, and personal beliefs to make sense of empirical data-and these subjective influences have often a

    With the booming of new technologies, biomedical science has transformed into digitalized, data intensive science. Massive amount of data need to be analyzed and interpreted, demand a complete pipeline to train next generation data scientists. To meet this need, the transinstitutional Big Data to Knowledge (BD2K) Initiative has been implemented since 2014, complementing other NIH institutional efforts. In this report, we give an overview the BD2K K01 mentored scientist career awards, which have demonstrated early success. We address the specific trainings needed in representative data science areas, in order to make the next generation of data scientists in biomedicine.

    We have developed Galaxy Zoo, a citizen science project in which volunteers classify images of galaxies by shape. The site has been hugely successful in reaching large numbers of people - more than 125,000 people have signed up. As a result, each galaxy has been classified more than 30 times, resulting in high-quality science results. We are studying the motivations of these volunteers to determine what about our site made it so captivating. We have some ideas - people enjoy helping science, looking at beautiful galaxy images, and the "game" nature of the interface. But we want to study the motivations systematically, to learn who thinks what, and how this affects what they do. We have designed a methodology in which we begin with interviews, asking open-ended questions of volunteers about their motivation. Then, we design a survey to collect motivation data for a larger sample. Lastly, for volunteers who agreed to give us their site username, we examine how they classified galaxies to look for correlations between motivation and behavior. In this poster, we describe our methodology and present preliminary results of our research.

    GREENLAND—Tom Lane and Suk Joon Lee, recent graduates of Dartmouth University's Thayer School of Engineering, in Hanover, N. H., are standing outside in the frigid cold testing an autonomous robot that could help with scientific research and logistics in harsh polar environments. This summer, Lane, Lee, and others are at Summit Station, a U.S. National Science Foundation (NSF)-sponsored scientific research station in Greenland, fine-tuning a battery-powered Yeti robot as part of a team working on the NSF-funded Cool Robot project. The station, also known as Summit Camp, is located on the highest point of the Greenland Ice Sheet (72°N, 38°W, 3200 meters above sea level) near the middle of the island. It is a proving ground this season for putting the approximately 68-kilogram, 1-cubic-meter robot through its paces, including improving Yeti's mobility capabilities and field-testing the robot. (See the electronic supplement to this Eos issue for a video of Yeti in action (http://www.agu.org/eos_elec/).) During field-testing, plans call for the robot to collect data on elevation and snow surface characteristics, including accumulation. In addition, the robot will collect black carbon and elemental carbon particulate matter air samples around Summit Camp's power generator to help study carbon dispersion over snow.

    The Science Communication Working Group (SCWG) at NASA Goddard Space Flight Center (GSFC) has been in existence since late 2007. The SCWG is comprised of education and public outreach (E/PO) professionals, public affairs specialists, scientists, and engineers. The goals of the SCWG are to identify barriers to scientist and engineer engagement in E/PO activities and to enable those scientists and engineers who wish to contribute to E/PO to be able to do so. SCWG members have held meetings with scientists and engineers across GSFC to determine barriers to their involvement in E/PO. During these meetings, SCWG members presented examples of successful, ongoing E/PO projects, encouraged active research scientists and engineers to talk about their own E/PO efforts and what worked for them, discussed the E/PO working environment, discussed opportunities for getting involved in E/PO (particularly in high-impact efforts that do not take much time), handed out booklets on effective E/PO, and asked scientists and engineers what they need to engage in E/PO. The identified barriers were consistent among scientists in GSFC's four science divisions (Earth science, planetary science, heliophysics, and astrophysics). Common barriers included 1) lack of time, 2) lack of funding support, 3) lack of value placed on doing E/PO by supervisors, 4) lack of training on doing appropriate/effective E/PO for different audiences, 5) lack of awareness and information about opportunities, 6) lack of understanding of what E/PO really is, and 7) level of effort required to do E/PO. Engineers reported similar issues, but the issues of time and funding support were more pronounced due to their highly structured work day and environment. Since the barriers were identified, the SCWG has taken a number of steps to address and rectify them. Steps have included holding various events to introduce scientists and engineers to E/PO staff and opportunities including an E/PO Open House, brown bag seminars on

    Moon Zoo is an online citizen science project with the aim of providing detailed crater counts for as much of the Moon's surface as possible. In addition to focusing on craters, volunteers are encouraged to remain vigilant for sightings of atypical features which may lead to new discoveries. Volunteers accomplish these tasks by exploring images captured by NASA's Lunar Reconnaissance Orbiter (LRO) which has a resolution of 50cm per pixel. To be successful, Moon Zoo needs to attract and retain a large population of citizen scientists. In this study, we examine the factors motivating Moon Zoo participants who invest many hours exploring these images. In this, the first of a two-phased study, we conducted a qualitative analysis using semi-structured interviews as a means of data collection. A stratified sample of participants was used in an attempt to uncover the driving forces behind decisions to participate from a wide-range of participants. Inquiring and probing questions were asked about factors which led volunteers to Moon Zoo as well as reasons which kept them committed to exploring the Moon's surface through this online portal. Responses were then categorized using a grounded theory approach, and frequency distributions are calculated where appropriate. Aggregate results from these interviews are presented here including the demographics of the sample and motivators as per the content analysis. The information gathered from this phase will be used to guide the development of an online survey to further explore volunteers’ motivation based on the presented classification schemes. The survey will then be used to guide future research and development in the area of citizen science in the field of astronomy. These findings will also be useful in charting new boundaries for future research.

    GLOBE at Night is an international science event designed to observe and record the visible stars as a means of measuring light pollution in a given location. Increased and robust understanding of our environment requires learning opportunities that take place outside of the conventional K-12 classroom and beyond the confines of the school day. This hands-on learning activity extended the traditional classroom and school day through 11 nights last March, when 18,000 citizen-scientists made over 4,500 observations from 96 countries. Utilizing the international networking capabilities of The GLOBE Program, GLOBE at Night was designed to make data collection and input user-friendly. Citizen-scientists were able to participate in this global scientific campaign by submitting their observations through an online database, allowing for authentic worldwide research and analysis by participating scientists. The data collected is available online in a variety of formats for use by students, teachers and scientists worldwide to assess how the quality of the night sky varies around the world. Using the online analysis tools provided by ESRI, participants were able to compare the observed data with population density and nighttime lighting datasets (DMSP Earth at Night). This comparison allowed correlations between observed data patterns and commonly used indices of population density and energy usage. This session will share our results and demonstrate how students and scientists across the globe can explore and analyze the results of this exciting campaign. We will discuss how the project team planned and executed the project in such a way that non-astronomers were able to make valid and useful contributions. We will also discuss lessons learned and best practices based on the 2006 campaign. GLOBE at Night is a collaborative effort sponsored by The GLOBE Program, the National Optical Astronomy Observatory (NOAO), Centro de Apoyo a la Didactica de la Astronomia (CADIAS

    The Planetary Science Education and Public Outreach (E/PO) Forum is a team of educators, scientists, and outreach professionals funded by NASA’s Science Mission Directorate (SMD) that supports SMD scientists currently involved in E/PO - or interested in becoming involved in E/PO efforts - to find ways to do so through a variety of avenues. There are many current and future opportunities and resources for scientists to become engaged in E/PO. The Forum provides tools for responding to NASA SMD E/PO funding opportunities (webinars and online proposal guides), a one-page Tips and Tricks guide for scientists to engage in education and public outreach, and a sampler of activities organized by thematic topic and NASA’s Big Questions in planetary science. Scientists can also locate resources for interacting with diverse audiences through a number of online clearinghouses, including: NASA Wavelength, a digital collection of peer-reviewed Earth and space science resources for educators of all levels (http://nasawavelength.org); the Year of the Solar System website (http://solarsystem.nasa.gov/yss), a presentation of thematic resources that includes background information, missions, the latest in planetary science news, and educational products, for use in the classroom and out, for teaching about the solar system organized by topic - volcanism, ice, astrobiology, etc.; and EarthSpace (http://www.lpi.usra.edu/earthspace), a community website where faculty can find and share resources and information about teaching Earth and space sciences in the undergraduate classroom, including class materials, news, funding opportunities, and the latest education research. Also recently developed, the NASA SMD Scientist Speaker’s Bureau (http://www.lpi.usra.edu/education/speaker) offers an online portal to connect scientists interested in getting involved in E/PO projects - giving public talks, classroom visits, and virtual connections - with audiences.

    Today as never before, America needs its citizens to be literate in science and technology. Not only must we only inspire a new generation of scientists and engineers and technologists, we must foster a society capable of meeting complex, 21st-century challenges. Unfortunately, the need for creative, flexible thinkers is growing at a time when our young students are lagging in science interest and performance. Over the past 17 years, the JASON Project has worked to link real science and scientists to the classroom. This link provide viable pipeline to creating the next generation scientists and researchers. Ultimately, JASON's mission is to improve the way science is taught by enabling students to learn directly from leading scientists. Through partnerships with agencies such as NOAA and NASA, JASON creates multimedia classroom products based on current scientific research. Broadcasts of science expeditions, hosted by leading researchers, are coupled with classroom materials that include interactive computer-based simulations, video- on-demand, inquiry-based experiments and activities, and print materials for students and teachers. A "gated" Web site hosts online resources and provides a secure platform to network with scientists and other classrooms in a nationwide community of learners. Each curriculum is organized around a specific theme for a comprehensive learning experience. It may be taught as a complete package, or individual components can be selected to teach specific, standards-based concepts. Such thematic units include: Disappearing Wetlands, Mysteries of Earth and Mars, and Monster Storms. All JASON curriculum units are grounded in "inquiry-based learning." The highly interactive curriculum will enable students to access current, real-world scientific research and employ the scientific method through reflection, investigation, identification of problems, sharing of data, and forming and testing hypotheses. JASON specializes in effectively applying

    The Young Engineers and Scientists (YES) Program is a community partnership between Southwest Research Institute (SwRI) and local high schools in San Antonio. It provides talented high school juniors and seniors a bridge between classroom instruction and real world, research experiences in physical sciences, information sciences, and engineering. YES consists of two parts: 1) An intensive three-week summer workshop held at SwRI where students experience the research environment first-hand; develop skills and acquire tools for solving scientific problems, attend mini-courses and seminars on electronics, C++ programming, the Internet, careers, science ethics, social impact of technology, and other topics; and select their individual research project with their mentor (SwRI staff member) to be completed during the academic year; and 2) A collegial mentorship where students complete individual research projects under the guidance of their mentors and teachers during the academic year and earn honors credit. At the end of the school year, students publicly present and display their work, acknowledging their accomplishments and spreading career awareness to other students and teachers. YES has been highly successful during the past nineteen (19) years. A total of 258 students have completed or are currently enrolled in YES. Of these students, 38% are females and 57% are ethnic minorities, reflecting the local diversity of the San Antonio area. All YES graduates have entered college, several work or have worked for SwRI, two businesses have formed, and three scientific publications have resulted. Sixteen (16) teacher participants have attended the YES workshop and have developed classroom materials based on their experiences in research at SwRI in the past three (3) years. In recognition of its excellence, YES received the Celebrate Success in 1996 and the Outstanding Campus Partner-of-the-Year Award in 2005, both from Northside Independent School District (San Antonio

    This anthology contains fourteen intriguing short stories by active research scientists and other writers trained in science. Science is at the heart of real science fiction, which is more than just westerns with ray guns or fantasy with spaceships. The people who do science and love science best are scientists. Scientists like Isaac Asimov, Arthur C. Clarke, and Fred Hoyle wrote some of the legendary tales of golden age science fiction. Today there is a new generation of scientists writing science fiction informed with the expertise of their fields, from astrophysics to computer science, biochemistry to rocket science, quantum physics to genetics, speculating about what is possible in our universe. Here lies the sense of wonder only science can deliver. All the stories in this volume are supplemented by afterwords commenting on the science underlying each story.
