Autonomous planetary rover at Carnegie Mellon

Science.gov (United States)

Whittaker, William; Kanade, Takeo; Mitchell, Tom

1990-01-01

This report describes progress in research on an autonomous robot for planetary exploration. In 1989, the year covered by this report, a six-legged walking robot, the Ambler, was configured, designed, and constructed. This configuration was used to overcome shortcomings exhibited by existing wheeled and walking robot mechanisms. The fundamental advantage of the Ambler is that the actuators for body support are independent of those for propulsion; a subset of the planar joints propel the body, and the vertical actuators support and level the body over terrain. Models of the Ambler's dynamics were developed and the leveling control was studied. An integrated system capable of walking with a single leg over rugged terrain was implemented and tested. A prototype of an Ambler leg is suspended below a carriage that slides along rails. To walk, the system uses a laser scanner to find a clear, flat foothold, positions the leg above the foothold, contacts the terrain with the foot, and applies force enough to advance the carriage along the rails. Walking both forward and backward, the system has traversed hundreds of meters of rugged terrain including obstacles too tall to step over, trenches too deep to step in, closely spaced rocks, and sand hills. In addition, preliminary experiments were conducted with concurrent planning and execution, and a leg recovery planner that generates time and power efficient 3D trajectories using 2D search was developed. A Hero robot was used to demonstrate mobile manipulation. Indoor tasks include collecting cups from the lab floor, retrieving printer output, and recharging when its battery gets low. The robot monitors its environment, and handles exceptional conditions in a robust fashion, using vision to track the appearance and disappearance of cups, onboard sonars to detect imminent collisions, and monitors to detect the battery level.

Natural scientists from Climate Central and social scientists from Carnegie Mellon University collaborated to develop science communications aimed at presenting personalized coastal flood risk information to the public. We encountered four main challenges: agreeing on goals; balancing complexity and simplicity; relying on data, not intuition; and negotiating external pressures. Each challenge demanded its own approach. We navigated agreement on goals through intensive internal communication early on in the project. We balanced complexity and simplicity through evaluation of communication materials for user understanding and scientific content. Early user test results that overturned some of our intuitions strengthened our commitment to testing communication elements whenever possible. Finally, we did our best to negotiate external pressures through regular internal communication and willingness to compromise.

The Archives of the Department of Terrestrial Magnetism: Documenting 100 Years of Carnegie Science

Science.gov (United States)

Hardy, S. J.

2005-12-01

The archives of the Department of Terrestrial Magnetism (DTM) of the Carnegie Institution of Washington document more than a century of geophysical and astronomical investigations. Primary source materials available for historical research include field and laboratory notebooks, equipment designs, plans for observatories and research vessels, scientists' correspondence, and thousands of expedition and instrument photographs. Yet despite its history, DTM long lacked a systematic approach to managing its documentary heritage. A preliminary records survey conducted in 2001 identified more than 1,000 linear feet of historically-valuable records languishing in dusty, poorly-accessible storerooms. Intellectual control at that time was minimal. With support from the National Historical Publications and Records Commission, the "Carnegie Legacy Project" was initiated in 2003 to preserve, organize, and facilitate access to DTM's archival records, as well as those of the Carnegie Institution's administrative headquarters and Geophysical Laboratory. Professional archivists were hired to process the 100-year backlog of records. Policies and procedures were established to ensure that all work conformed to national archival standards. Records were appraised, organized, and rehoused in acid-free containers, and finding aids were created for the project web site. Standardized descriptions of each collection were contributed to the WorldCat bibliographic database and the AIP International Catalog of Sources for History of Physics. Historic photographs and documents were digitized for online exhibitions to raise awareness of the archives among researchers and the general public. The success of the Legacy Project depended on collaboration between archivists, librarians, historians, data specialists, and scientists. This presentation will discuss key aspects (funding, staffing, preservation, access, outreach) of the Legacy Project and is aimed at personnel in observatories, research

"PROPAGANDISTS FOR THE BEHAVIORAL SCIENCES": THE OVERLOOKED PARTNERSHIP BETWEEN THE CARNEGIE CORPORATION AND SSRC IN THE MID-TWENTIETH CENTURY.

Science.gov (United States)

Hauptmann, Emily

2016-01-01

The Carnegie Corporation's role as a patron of the behavioral sciences has been overlooked; its support for the behavioral sciences not only began earlier than the Ford Foundation's but was also at least equally important to their success. I show how the close postwar collaboration between the Carnegie Corporation and the Social Science Research Council (SSRC) to promote the behavioral sciences emerged after a struggle between Carnegie and the Rockefeller Foundation over the direction and leadership of the SSRC. I then focus on three postwar projects Carnegie helped conceive and fund that were publicized as the work of the SSRC: Chase's The Proper Study of Mankind (1948), Stouffer et al.'s The American Soldier (), and the Michigan's Survey Research Center 1952 election study. In each of these projects, Carnegie deliberately muted its own role and promoted the remade SSRC as a major advocate for the behavioral sciences. © 2016 Wiley Periodicals, Inc.

Metazoan physiology depends on intricate patterns of gene expression that remain poorly known. Using transposon mutagenesis in Drosophila, we constructed a library of 7404 protein trap and enhancer trap lines, the Carnegie collection, to facilitate gene expression mapping at single-cell resolution. By sequencing the genomic insertion sites, determining splicing patterns downstream of the enhanced green fluorescent protein (EGFP) exon, and analyzing expression patterns in the ovary and salivary gland, we found that 600-900 different genes are trapped in our collection. A core set of 244 lines trapped different identifiable protein isoforms, while insertions likely to act as GFP-enhancer traps were found in 256 additional genes. At least 8 novel genes were also identified. Our results demonstrate that the Carnegie collection will be useful as a discovery tool in diverse areas of cell and developmental biology and suggest new strategies for greatly increasing the coverage of the Drosophila proteome with protein trap insertions.

Enacting the Carnegie Foundation call for reform of medical school and residency.

Science.gov (United States)

O'Brien, Bridget C; Irby, David M

2013-01-01

On the 100th anniversary of the Flexner Report, the Carnegie Foundation for the Advancement of Teaching published a new study of medical education. This study, titled Educating Physicians: A Call for Reform of Medical Schools and Residency Programs, contained four primary recommendations intended to stimulate innovation and improvement in medical education. In this article, the authors examined the ways others have applied the four recommendations from Educating Physicians within and beyond medical education. In their review of 246 publications citing the Carnegie work, they found that the recommendation for integration was addressed most frequently, often through descriptions of integration of curricular content in undergraduate medical education. The recommendation to focus on professional identity formation was the second most frequently addressed, followed by standardization and individualization, then inquiry, innovation, and improvement. The publications related to these latter three recommendations tended to be conceptual rather than descriptive or empirical. Publications spanned the continuum of medical education (from medical school to residency to physicians in practice) and even into other fields, but undergraduate medical education received the most attention. The authors discuss common themes among the citing publications and highlight opportunities for further discussion and innovation. Many exciting developments have occurred in medical education and beyond since the publication of Educating Physicians in 2010. Thus far, most of the publications citing the Carnegie recommendations describe incremental changes in medical education, particularly in the area of integration. Some of the conceptual work around these recommendations, coupled with a variety of external factors such as changes in health care and accreditation systems, suggests the potential for changes that are more transformative in nature.

Santolaya-Forgas, Joaquin; De Leon-Luis, Juan; Friel, Lara A; Wolf, Roman

2007-09-01

The objective of this study was to determine if very early ultrasonographic measurements obtained from human and baboon are comparable. For this purpose, the gestational, amniotic and yolk sacs, embryonic crown rump length (CRL) and heart rate were measured ultrasonographically between 35 and 47 days from the mean day of a three-day mating period in baboons (n=18) and between 42 to 58 days from fertilization as calculated from the CRL measurements in human pregnancies (n=82). Ultrasonographic measurements from both species were then plotted in the same graph using Carnegie stages of embryonic development as the independent variable to allow for visual comparisons. Mean gestational age at ultrasonographic studies was significantly different for humans and baboons (50.4 vs. 41 days, respectively; p>0.01). Significant correlations (p>0.01) were noted between ultrasonographic measurements and Carnegie stages of development in both humans and baboons. Only the gestational and the yolk sacs were significantly smaller in baboons than in humans (p>0.05). The findings that embryonic CRL, extra-embryonic space and heart rate are very similar between the 17th and 23rd Carnegie developmental stages make the baboon a promising surrogate of human pregnancy for investigations using celocentesis.

Full Text Available Objective – To better understand the feelings of college freshmen engaged in their first research project using an academic library.Design – Interpretive study involving analysis of personal writing describing the students’ research process and their reactions to it.Setting – A medium-sized public university in the southeastern United States.Subjects – Students in freshman English courses.Methods – English instructors assigned students to maintain search journals in which the students recorded a detailed description of their research process and the feelings they experienced while conducting research. In addition, students had to write an end-of- semester, in-class essay in which they discussed their initial reactions to the research project and how their feelings evolved over the semester. The journals and essays were analyzed using the “constant comparative” method developed by Glaser and Strauss to identify “recurrent ‘themes’” (161. Main Results – 75 to 85 per cent of the students reported feelings of “fear or anxiety” when confronted with the research assignment. More specifically, they expressed a sense of being “lost”. This feeling derived from four causes: “(1 the size of the library; (2 a lack of knowledge about where things were located; (3 how to begin, and (4 what to do” (162. Spurred by the question of why students did not seek help from their professors or a librarian, Mellon re-examined the data and uncovered two additional prevalent feelings. Most students tended to believe that their fellow students did not share their lack of library skills. They were ashamed of what they considered their own inadequacy and were, therefore, unwilling to reveal it by asking for assistance (162.Conclusions – The original objective of Mellon’s study was to gain information that would be useful in improving bibliographic instruction in her library.

The configuration of the Carnegie-Mellon University Ambler, a six-legged autonomous walking vehicle for exploring Mars, enables the recovery of a trailing leg past the leading leg to reduce the energy expenditure in terrain interactions. In this article, gaits developed for this unprecedented configuration are described. A stability criterion has been developed that ensures stability of the vehicle in the event of failure of any one of the supporting legs. Periodic gaits developed for the Ambler utilize the Ambler's unique abilities and continuously satisfy the stability criterion.

COSMOS: Carnegie Observatories System for MultiObject Spectroscopy

Science.gov (United States)

Oemler, A.; Clardy, K.; Kelson, D.; Walth, G.; Villanueva, E.

2017-05-01

COSMOS (Carnegie Observatories System for MultiObject Spectroscopy) reduces multislit spectra obtained with the IMACS and LDSS3 spectrographs on the Magellan Telescopes. It can be used for the quick-look analysis of data at the telescope as well as for pipeline reduction of large data sets. COSMOS is based on a precise optical model of the spectrographs, which allows (after alignment and calibration) an accurate prediction of the location of spectra features. This eliminates the line search procedure which is fundamental to many spectral reduction programs, and allows a robust data pipeline to be run in an almost fully automatic mode, allowing large amounts of data to be reduced with minimal intervention.

Rising to the challenge: Training the next generation of clinician scientists for South Africa

Directory of Open Access Journals (Sweden)

B Kramer

2015-12-01

Full Text Available Background. A shortage of clinician scientists globally, particularly in the developing world, including Africa and South Africa (SA, is well known and was recently highlighted in a consensus report by the Academy of Science of South Africa. There is a need to find innovative ways to develop and advance clinician scientists in SA. Objective. To provide opportunities for young clinicians to develop research skills through enrolling for a PhD. Method. To address this need in SA, we developed an innovative programme over 2 years in collaboration with the Carnegie Corporation of New York to support and train young specialist clinicians in research as the next generation of clinician scientists, through a full-time PhD programme. Results. Since initiation of the programme in March 2011, 16 such specialists have been enrolled at intervals in the Fellowship programme, 5 have qualified with PhDs, while a further 3 are expected to qualify shortly. Publications and presentations at congresses have been recorded as well as grant applications. Discussion. Although the programme is seen as an important initial step in addressing the shortage of clinician scientists, its dependence on donor funding and the lack of a secure career path for clinicians wishing to spend more of their career in research pose problems for the programme’s sustainability. It is hoped that the positive outcomes of this experience will initiate further programmes of this kind at academic institutions and attract the attention of funders and universities in order to sustain and enlarge this initiative.

Calls for reform of medical education by the Carnegie Foundation for the Advancement of Teaching: 1910 and 2010.

Science.gov (United States)

Irby, David M; Cooke, Molly; O'Brien, Bridget C

2010-02-01

The Carnegie Foundation for the Advancement of Teaching, which in 1910 helped stimulate the transformation of North American medical education with the publication of the Flexner Report, has a venerated place in the history of American medical education. Within a decade following Flexner's report, a strong scientifically oriented and rigorous form of medical education became well established; its structures and processes have changed relatively little since. However, the forces of change are again challenging medical education, and new calls for reform are emerging. In 2010, the Carnegie Foundation will issue another report, Educating Physicians: A Call for Reform of Medical School and Residency, that calls for (1) standardizing learning outcomes and individualizing the learning process, (2) promoting multiple forms of integration, (3) incorporating habits of inquiry and improvement, and (4) focusing on the progressive formation of the physician's professional identity. The authors, who wrote the 2010 Carnegie report, trace the seeds of these themes in Flexner's work and describe their own conceptions of them, addressing the prior and current challenges to medical education as well as recommendations for achieving excellence. The authors hope that the new report will generate the same excitement about educational innovation and reform of undergraduate and graduate medical education as the Flexner Report did a century ago.

The Pennsylvania State University Nuclear Engineering Distance Education Program has a twenty year history of providing graduate level distance education in Nuclear Engineering. The Distance Education Program was initiated as a specific program which was developed for the Westinghouse Energy Systems Divisions in Pittsburgh. In 1983, Carnegie-Mellon University (CMU) decided to terminate its small Nuclear Engineering Program. Up until that time, Westinghouse employees could enroll at CMU for graduate classes in Nuclear Engineering as well as other engineering disciplines and could obtain a masters degree or if desired, could continue for a Ph.D. degree.

Is periconceptional maternal one-carbon (I-C) metabolism associated with embryonic morphological development in non-malformed ongoing pregnancies? Serum vitamin B12, red blood cell (RBC) folate and plasma total homocysteine (tHcy) are associated with embryonic development according to the Carnegie stages. Derangements in maternal I-C metabolism affect reproductive and pregnancy outcomes, as well as future health of the offspring. Between 2010 and 2014, women with singleton ongoing pregnancies were enrolled in a prospective periconceptional cohort study. A total of 234 pregnancies, including 138 spontaneous or IUI pregnancies with strict pregnancy dating and 96 pregnancies derived from IVF, ICSI or cryopreserved embryo transfer (IVF/ICSI pregnancies), underwent longitudinal transvaginal three-dimensional ultrasound (3D US) scans from 6+0 up to 10+2 weeks of gestation. Carnegie stages were defined using internal and external morphologic criteria in a virtual reality system. Maternal venous blood samples were collected at enrollment for serum vitamin B12, RBC folate and plasma tHcy assessment. Associations between biomarker concentrations and longitudinal Carnegie stages were investigated using linear mixed models. We performed a median of three 3D US scans per pregnancy (range 1-5) resulting in 600 good quality data sets for the Carnegie stage annotation (80.5%). Vitamin B12 was positively associated with embryonic development in the total study population (β = 0.001 (95% CI: 0.000; 0.002), P Carnegie stages only in IVF/ICSI pregnancies (β = 0.001 (95% CI: 0.0005; 0.0015), P < 0.05). In this group, low RBC folate concentrations (-2SD, 875.4 nmol/l) were associated with a 1.8-day delay (95% CI: 1.7-1.8) in development compared with high concentrations (+2SD, 2119.9 nmol/l). tHcy was negatively associated with embryonic development in the total study population (β = -0.08 (95% CI: -0.14; -0.02), P < 0.01), as well as in the IVF/ICSI subgroup (β = -0.08 (95% CI: -0

Dante's Inferno

Science.gov (United States)

Researchers decided last week to make a second rescue attempt of NASA's Dante II robot from the grips of Alaska's active volcano Mt. Spurr. After completing a successful mission earlier this month to explore depths of the crater where no human would venture, the eight-legged robot was disabled as it was working its way out of the crater. A first rescue attempt last Wednesday by helicopter failed to recover the $1.7-million robot. Nonetheless, NASA and Carnegie Mellon researchers, who developed the robot, maintain that Dante IPs trek shows that robots can do research in places—on Earth and in space—that may be too dangerous for human exploration.

2005-08-31

Carnegie Mellon University was teamed with the Alcoa Technical Center with support from the US Dept. of Energy (Office of Industrial Technology) and the Pennsylvania Technology Investment Authority (PTIA) to make processing of aluminum less costly and more energy efficient. Researchers in the Department of Materials Science and Engineering have investigated how annealing processes in the early stages of aluminum processing affect the structure and properties of the material. Annealing at high temperatures consumes significant amounts of time and energy. By making detailed measurements of the crystallography and morphology of internal structural changes they have generated new information that will provide a scientific basis for shortening processing times and consuming less energy during annealing.

Modeling man: the monkey colony at the Carnegie Institution of Washington's Department of Embryology, 1925-1971.

Science.gov (United States)

Wilson, Emily K

2012-01-01

Though better recognized for its immediate endeavors in human embryo research, the Carnegie Department of Embryology also employed a breeding colony of rhesus macaques for the purposes of studying human reproduction. This essay follows the course of the first enterprise in maintaining a primate colony for laboratory research and the overlapping scientific, social, and political circumstances that tolerated and cultivated the colony's continued operation from 1925 until 1971. Despite a new-found priority for reproductive sciences in the United States, by the early 1920s an unfertilized human ovum had not yet been seen and even the timing of ovulation remained unresolved. Progress would require an organized research approach that could extend beyond the limitations of working with scant and inherently restrictive human subjects or with common lab mammals like mice. In response, the Department of Embryology, under the Carnegie Institution of Washington (CIW), instituted a novel methodology using a particular primate species as a surrogate in studying normal human reproductive physiology. Over more than 40 years the monkey colony followed an unpremeditated trajectory that would contribute fundamentally to discoveries in human reproduction, early embryo development, reliable birth control methods, and to the establishment of the rhesus macaque as a common model organism.

The galaxy builders

Cho, Adrian

2018-06-01

Philip Hopkins, a theoretical astrophysicist at the California Institute of Technology in Pasadena, likes to prank his colleagues. An expert in simulating the formation of galaxies, Hopkins sometimes begins his talks by projecting images of his creations next to photos of real galaxies and defying his audience to tell them apart. "We can even trick astronomers," Hopkins says. For decades, scientists have tried to simulate how the trillions of galaxies in the observable universe arose from clouds of gas after the big bang. But only in the past few years have the simulations begun to reproduce both the details of individual galaxies and their distribution of masses and shapes. As the fake universes improve, their role is also changing. Previously, information flowed one way: from the astronomers studying real galaxies to the modelers trying to simulate them. Now, insight is flowing the other way, too, with the models helping guide astronomers and astrophysicists. The models suggest that the earliest galaxies were oddly pickle-shaped, that wafer-thin spiral galaxies are surprisingly rugged in the face of collisions, and, perhaps most important, that galaxies must form stars far more slowly than astrophysicists expected. Progress is coming so fast, says Tiziana Di Matteo, a numerical cosmologist at Carnegie Mellon University in Pittsburgh, Pennsylvania, that "the whole thing has reached this little golden age."

Supernovae are essential to understanding the chemical evolution of the universe. Type Ia supernovae also provide the most powerful observational tool currently available for studying the expansion history of the universe and the nature of dark energy. Our basic knowledge of supernovae comes from the study of their photometric and spectroscopic properties. However, the presently available data sets of optical and near-infrared light curves of supernovae are rather small and/or heterogeneous, and employ photometric systems that are poorly characterized. Similarly, there are relatively few supernovae whose spectral evolution has been well sampled, both in wavelength and phase, with precise spectrophotometric observations. The low-redshift portion of the Carnegie Supernova Project (CSP) seeks to remedy this situation by providing photometry and spectrophotometry of a large sample of supernovae taken on telescope/filter/detector systems that are well understood and well characterized. During a 5 year program that began in 2004 September, we expect to obtain high-precision u'g'r'i'BVYJHKs light curves and optical spectrophotometry for about 250 supernovae of all types. In this paper we provide a detailed description of the CSP survey observing and data reduction methodology. In addition, we present preliminary photometry and spectra obtained for a few representative supernovae during the first observing campaign.

Some aspects of human embryogenesis and organogenesis remain unclear, especially concerning the development of the liver and its vasculature. The purpose of this study was to investigate, from a descriptive standpoint, the evolutionary morphogenesis of the human liver and its vasculature by computerized three-dimensional reconstructions of human embryos. Serial histological sections of four human embryos at successive stages of development belonging to three prestigious French historical collections were digitized and reconstructed in 3D using software commonly used in medical radiology. Manual segmentation of the hepatic anatomical regions of interest was performed section by section. In this study, human liver organogenesis was examined at Carnegie stages 14, 18, 21 and 23. Using a descriptive and an analytical method, we showed that these stages correspond to the implementation of the large hepatic vascular patterns (the portal system, the hepatic artery and the hepatic venous system) and the biliary system. To our knowledge, our work is the first descriptive morphological study using 3D computerized reconstructions from serial histological sections of the embryonic development of the human liver between Carnegie stages 14 and 23.

The production of enantiomerically pure chiral compounds is of great importance in the pharmaceutical industry. Although processes involving chiral catalysis and separations involving solid surfaces are known, the molecular-scale details of these processes are not well understood. This lack of understanding strongly limits the development of new chiral processes. Our collaborative research effort examines several intertwined aspects of chirality and enantioselectivity at catalytically active metal surfaces. At Carnegie Mellon, our efforts focus on the development of chirally imprinted metal powders as materials for chiral columns and the experimental and theoretical study of small chiral molecules adsorbed on well-characterized metal surfaces, both achiral and chiral. These efforts are being performed in close collaboration with our team members at the University of California Riverside and the University of Wisconsin Milwaukee

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.

The Carnegie-Irvine Galaxy Survey (CGS) is a comprehensive investigation of the physical properties of a complete, representative sample of 605 bright (B T ≤ 12.9 mag) galaxies in the southern hemisphere. This contribution describes the isophotal analysis of the broadband (BVRI) optical imaging component of the project. We pay close attention to sky subtraction, which is particularly challenging for some of the large galaxies in our sample. Extensive crosschecks with internal and external data confirm that our calibration and sky subtraction techniques are robust with respect to the quoted measurement uncertainties. We present a uniform catalog of one-dimensional radial profiles of surface brightness and geometric parameters, as well as integrated colors and color gradients. Composite profiles highlight the tremendous diversity of brightness distributions found in disk galaxies and their dependence on Hubble type. A significant fraction of S0 and spiral galaxies exhibit non-exponential profiles in their outer regions. We perform Fourier decomposition of the isophotes to quantify non-axisymmetric deviations in the light distribution. We use the geometric parameters, in conjunction with the amplitude and phase of the m = 2 Fourier mode, to identify bars and quantify their size and strength. Spiral arm strengths are characterized using the m = 2 Fourier profiles and structure maps. Finally, we utilize the information encoded in the m = 1 Fourier profiles to measure disk lopsidedness. The databases assembled here and in Paper I lay the foundation for forthcoming scientific applications of CGS.

The goal in this paper was to rebuild a three dimensional (3D) reconstruction of the dorsal and ventral pancreatic buds, in the human embryos, at Carnegie stages 15-23. The early development of the pancreas is studied by tissue observation and reconstruction by a computer-assisted method, using a light micrograph images from consecutive serial sagittal sections (diameter 7 microm) of ten human embryos ranging from Carnegie stages 15-23, CRL 7-27 mm, fixed, dehydrated and embedded in paraffin, were stained alternately with haematoxylin-eosin or Heindenhain'Azan. The images were digitalized by Canon Camera 350 EOS D. The serial views were aligned automatically by software, manual alignment was performed, the data were analysed following segmentation and threshold. The two buds were clearly identified at stage 15. In stage 16, both pancreatic buds were in final position, and begin to merge in stage 17. From stage 18 to the stage 23, surrounding connective tissue differentiated. In the stage 23, the morphology of the pancreas was definitive. The superior portion of the anterior face of the pancreas's head was arising from the dorsal bud. The rest of the head including the uncinate process emanated from the ventral bud. The 3D computer-assisted reconstruction of the human pancreas visualized the relationships between the two pancreatic buds. This explains the disposition and the modality of the components fusion. This embryologic development permits a better understanding of congenital abnormalities.

The Oratorical Scientist: A Guide for Speechcraft and Presentation for Scientists

Lau, G. E.

2015-12-01

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.

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.

1999-01-01

NPG 7120.5A, "NASA Program and Project Management Processes and Requirements" enacted in April, 1998, requires that "The program or project manager shall apply risk management principles..." The Software Assurance Technology Center (SATC) at NASA GSFC has been tasked with the responsibility for developing and teaching a systems level course for risk management that provides information on how to comply with this edict. The course was developed in conjunction with the Software Engineering Institute at Carnegie Mellon University, then tailored to the NASA systems community. This presentation will briefly discuss the six functions for risk management: (1) Identify the risks in a specific format; (2) Analyze the risk probability, impact/severity, and timeframe; (3) Plan the approach; (4) Track the risk through data compilation and analysis; (5) Control and monitor the risk; (6) Communicate and document the process and decisions.

Teachers of physics can often lack the type of support they desperately need. The Physics Teaching Web Advisory (Pathway) is a dynamic digital library for physics teaching that is designed to offer such support. Carnegie Mellon University’s synthetic interview technology provides the foundation for a system that allows physics teachers to ask questions of a virtual mentor and get video responses. A log of the questions asked of our system provides a rich database of information about just what types of support teachers are requesting. This talk will present a summary of the common types of questions teachers ask. Such information is valuable as we design support systems for physics teachers, both new and experienced. In addition, recent progress and developments will be discussed. Supported by NSF grant numbers DUE-0226157, DUE-0226219, ESI-0455772 & ESI-0455813

Evolution of an artificial neural network based autonomous land vehicle controller.

Science.gov (United States)

Baluja, S

1996-01-01

This paper presents an evolutionary method for creating an artificial neural network based autonomous land vehicle controller. The evolved controllers perform better in unseen situations than those trained with an error backpropagation learning algorithm designed for this task. In this paper, an overview of the previous connectionist based approaches to this task is given, and the evolutionary algorithms used in this study are described in detail. Methods for reducing the high computational costs of training artificial neural networks with evolutionary algorithms are explored. Error metrics specific to the task of autonomous vehicle control are introduced; the evolutionary algorithms guided by these error metrics reveal improved performance over those guided by the standard sum-squared error metric. Finally, techniques for integrating evolutionary search and error backpropagation are presented. The evolved networks are designed to control Carnegie Mellon University's NAVLAB vehicles in road following tasks.

Examined are its origins as a hybrid of philosophy and mathematics, the maturity and institutionalisation attained under the label “logic and foundations,” a second wave of institutionalisation in the Postwar period, and the institutional developments since 1975 in connection with computer science and with the study of language and informatics. Although some “internal history” is discussed, the main focus is on the emergence, consolidation and convolutions of logic as a discipline, through various professional associations and journals, in centers such as Torino, Göttingen, Warsaw, Berkeley, Princeton, Carnegie Mellon, Stanford, and Amsterdam.

Robotic and user interface solutions for hazardous and remote applications

International Nuclear Information System (INIS)

Schempf, H.

1997-01-01

Carnegie Mellon University (CMU) is developing novel robotic and user interface systems to assist in the cleanup activities undertaken by the U.S. Department of Energy (DOE). Under DOE's EM-50 funding and administered by the Federal Energy Technology Center (FETC), CMU has developed a novel asbestos pipe-insulation abatement robot system, called BOA, and a novel generic user interface control and training console, dubbed RoboCon. The use of BOA will allow the speedier abatement of the vast DOE piping networks clad with hazardous and contaminated asbestos insulation by which overall job costs can be reduced by as much as 50%. RoboCon will allow the DOE to evaluate different remote and robotic system technologies from the overall man-machine performance standpoint, as well as provide a standardized training platform for training site operators in the operation of remote and robotic equipment

Over the course of this project, we have analyzed data and samples from the Carbonaceous Aerosol and Radiative Effects Study (CARES) and the Clear air for London (ClearfLo) campaign, as well as conducted or participated in laboratory experiments designed to better understand black carbon mixing state and climate-relevant properties. The laboratory campaigns took place at the Pacific Northwest National Laboratory and Carnegie Mellon University to study various climate-relevant aerosol properties of different sources of soot mixing with secondary organic aerosol precursors. Results from some of these activities were summarized in the previous progress report. This final report presents the manuscripts that have been published (many in the period since the last progress report), lists presentations at different conferences based on grant-related activities, and presents some results that are likely to be submitted for publication in the near future.

DiMaria-Ghalili, Rose Ann; Ostrow, C Lynne

2009-02-01

This article describes the authors' experiences during 3 years of using Microsoft Excel to teach graduate-level statistics, as part of the research core required by the American Association of Colleges of Nursing for all professional graduate nursing programs. The advantages to using this program instead of specialized statistical programs are ease of accessibility, increased transferability of skills, and reduced cost for students. The authors share their insight about realistic goals for teaching statistics to master's-level students and the resources that are available to faculty to help them to learn and use Excel in their courses. Several online sites that are excellent resources for both faculty and students are discussed. Detailed attention is given to an online course (Carnegie-Mellon University Open Learning Initiative, n.d.), which the authors have incorporated into their graduate-level research methods course.

An Earth System Scientist Network for Student and Scientist Partnerships

Ledley, T. S.

2001-05-01

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

We performed a morphometric study of cardiac development on human embryos to complement the scarce data on human embryonic cardiac morphometry and to attempt to establish, from these, algorithms describing cardiac growth during the second month of gestation. Thirty human embryos from Carnegie stages 15-23 were included in the study. Shrinkage and compression effects from fixation and inclusion in paraffin were considered in our calculations. Growth of the cardiac (whole heart) volume and volume of ventricular myocardium through the Carnegie stages were analysed by ANOVA. Linear correlation was used to describe the relationship between the ventricular myocardium and cardiac volumes. Comparisons of models were carried out through the R2 statistic. The relationship volume of ventricular myocardium versus cardiac volume is expressed by the equation: cardiac volume = 0.6266 + 2.4778 volume of ventricular myocardium. The relationship cardiac volume versus crown-rump length is expressed by the equation: cardiac volume = 1.3 e(0.126 CR length), where e is the base of natural logarithms. At a clinical level, these results can contribute towards the establishment of a normogram for cardiac development, useful for the design of strategies for early diagnosis of congenital heart disease. They can also help in the study of embryogenesis, for example in the discussion of ventricular trabeculation. Copyright 2007 S. Karger AG, Basel.

Radio Astronomers Develop New Technique for Studying Dark Energy

capabilities of current instruments -- the team used their intensity-mapping technique to accumulate the radio waves emitted by the hydrogen gas in large volumes of space including many galaxies. "Since the early part of the 20th Century, astronomers have traced the expansion of the Universe by observing galaxies. Our new technique allows us to skip the galaxy-detection step and gather radio emissions from a thousand galaxies at a time, as well as all the dimly-glowing material between them," said Jeffrey Peterson, of Carnegie Mellon University. The astronomers also developed new techniques that removed both man-made radio interference and radio emission caused by more-nearby astronomical sources, leaving only the extremely faint radio waves coming from the very distant hydrogen gas. The result was a map of part of the "cosmic web" that correlated neatly with the structure shown by the earlier optical study. The team first proposed their intensity-mapping technique in 2008, and their GBT observations were the first test of the idea. "These observations detected more hydrogen gas than all the previously-detected hydrogen in the Universe, and at distances ten times farther than any radio wave-emitting hydrogen seen before," said Ue-Li Pen of the University of Toronto. "This is a demonstration of an important technique that has great promise for future studies of the evolution of large-scale structure in the Universe," said National Radio Astronomy Observatory Chief Scientist Chris Carilli, who was not part of the research team. In addition to Chang, Peterson, and Pen, the research team included Kevin Bandura of Carnegie Mellon University. The scientists reported their work in the July 22 issue of the scientific journal Nature.

In providing an independent measure of the expansion history of the universe, the Carnegie Supernova Project (CSP) has observed 71 high-z Type Ia supernovae (SNe Ia) in the near-infrared bands Y and J. These can be used to construct rest-frame i-band light curves which, when compared to a low-z sample, yield distance moduli that are less sensitive to extinction and/or decline-rate corrections than in the optical. However, working with NIR observed and i-band rest-frame photometry presents unique challenges and has necessitated the development of a new set of observational tools in order to reduce and analyze both the low-z and high-z CSP sample. We present in this paper the methods used to generate uBVgriYJH light-curve templates based on a sample of 24 high-quality low-z CSP SNe. We also present two methods for determining the distances to the hosts of SN Ia events. A larger sample of 30 low-z SNe Ia in the Hubble flow is used to calibrate these methods. We then apply the method and derive distances to seven galaxies that are so nearby that their motions are not dominated by the Hubble flow.

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

Scientists Shaping the Discussion

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.

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.

How to Grow Project Scientists: A Systematic Approach to Developing Project Scientists

Science.gov (United States)

Kea, Howard

2011-01-01

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.

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

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

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.

Entrepreneurship for Creative Scientists

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.

The critical role of culture and environment as determinants of women's participation in computer science

Science.gov (United States)

Frieze, Carol

This thesis proposes the need for, and illustrates, a new approach to how we think about, and act on, issues relating to women's participation, or lack of participation, in computer science (CS). This approach is based on a cultural perspective arguing that many of the reasons for women entering---or not entering---CS programs have little to do with gender and a lot to do with environment and culture. Evidence for this approach comes primarily from a qualitative, research study, which shows the effects of changes in the micro-culture on CS undergraduates at Carnegie Mellon, and from studies of other cultural contexts that illustrate a "Women-CS fit". We also discuss the interventions that have been crucial to the evolution of this specific micro-culture. Our argument goes against the grain of many gender and CS studies which conclude that the reasons for women's low participation in CS are based in gender --and particularly in gender differences in how men and women relate to the field. Such studies tend to focus on gender differences and recommend accommodating (what are perceived to be) women's different ways of relating to CS. This is often interpreted as contextualizing the curriculum to make it "female-friendly". The CS curriculum at Carnegie Mellon was not contextualized to be "female-friendly". Nevertheless, over the past few years, the school has attracted and graduated well above the US national average for women in undergraduate CS programs. We argue that this is due in large part to changes in the culture and environment of the department. As the environment has shifted from an unbalanced to a more balanced environment (balanced in terms of gender, breadth of student personalities, and professional support for women) the way has been opened for a range of students, including a significant number of women, to participate, and be successful, in the CS major. Our research shows that as men and women inhabit, and participate in, a more balanced environment

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

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

Science.gov (United States)

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.

Neya Systems, LLC competed in the CANINE program sponsored by the U.S. Army Tank Automotive Research Development and Engineering Center (TARDEC) which culminated in a competition held at Fort Benning as part of the 2012 Robotics Rodeo. As part of this program, we developed a robot with the capability to learn and recognize the appearance of target objects, conduct an area search amid distractor objects and obstacles, and relocate the target object in the same way that Mine dogs and Sentry dogs are used within military contexts for exploration and threat detection. Neya teamed with the Robotics Institute at Carnegie Mellon University to develop vision-based solutions for probabilistic target learning and recognition. In addition, we used a Mission Planning and Management System (MPMS) to orchestrate complex search and retrieval tasks using a general set of modular autonomous services relating to robot mobility, perception and grasping.

Integrated assessment models of climate change. An incomplete overview

International Nuclear Information System (INIS)

Dowlatabadi, H.

1995-01-01

Integrated assessment is a trendy phrase that has recently entered the vocabulary of folks in Washington, DC and elsewhere. The novelty of the term in policy analysis and policy making circles belies the longevity of this approach in the sciences and past attempts at their application to policy issues. This paper is an attempt at providing an overview of integrated assessment with a special focus on policy motivated integrated assessments of climate change. The first section provides an introduction to integrated assessments in general, followed by a discussion of the bounds to the climate change issue. The next section is devoted to a taxonomy of the policy motivated models. Then the integrated assessment effort at Carnegie Mellon is described briefly. A perspective on the challenges ahead in successful representation of natural and social dynamics in integrated assessments of global climate change is presented in the final section. (Author)

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

This paper 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.

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.

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.

The Carnegie Supernova Project (CSP) was a five-year observational survey conducted at Las Campanas Observatory that obtained, among other things, high-quality light curves of ∼100 low-redshift Type Ia supernovae (SNe Ia). Presented here is the second data release of nearby SN Ia photometry consisting of 50 objects, with a subset of 45 having near-infrared follow-up observations. Thirty-three objects have optical pre-maximum coverage with a subset of 15 beginning at least five days before maximum light. In the near-infrared, 27 objects have coverage beginning before the epoch of B-band maximum, with a subset of 13 beginning at least five days before maximum. In addition, we present results of a photometric calibration program to measure the CSP optical (uBgVri) bandpasses with an accuracy of ∼1%. Finally, we report the discovery of a second SN Ia, SN 2006ot, similar in its characteristics to the peculiar SN 2006bt.

The Carnegie Supernova Project (CSP) is a five-year survey being carried out at the Las Campanas Observatory to obtain high-quality light curves of ∼100 low-redshift Type Ia supernovae (SNe Ia) in a well-defined photometric system. Here we present the first release of photometric data that contains the optical light curves of 35 SNe Ia, and near-infrared light curves for a subset of 25 events. The data comprise 5559 optical (ugriBV) and 1043 near-infrared (Y JHK s ) data points in the natural system of the Swope telescope. Twenty-eight SNe have pre-maximum data, and for 15 of these, the observations begin at least 5 days before B maximum. This is one of the most accurate data sets of low-redshift SNe Ia published to date. When completed, the CSP data set will constitute a fundamental reference for precise determinations of cosmological parameters, and serve as a rich resource for comparison with models of SNe Ia.

Everyone Knows What a Scientist Looks Like: The Image of a Modern Scientist

Enevoldsen, A. A. G.

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.

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

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.

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

Lippi, Giuseppe; Mattiuzzi, Camilla

2017-08-01

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

The Carnegie Supernova Project: Intrinsic colors of type Ia supernovae

2014-01-01

We present an updated analysis of the intrinsic colors of Type Ia supernova (SNe Ia) using the latest data release of the Carnegie Supernova Project. We introduce a new light-curve parameter very similar to stretch that is better suited for fast-declining events, and find that these peculiar types can be seen as extensions to the population of 'normal' SNe Ia. With a larger number of objects, an updated fit to the Lira relation is presented along with evidence for a dependence on the late-time slope of the B – V light-curves with stretch and color. Using the full wavelength range from u to H band, we place constraints on the reddening law for the sample as a whole and also for individual events/hosts based solely on the observed colors. The photometric data continue to favor low values of R V , though with large variations from event to event, indicating an intrinsic distribution. We confirm the findings of other groups that there appears to be a correlation between the derived reddening law, R V , and the color excess, E(B – V), such that larger E(B – V) tends to favor lower R V . The intrinsic u-band colors show a relatively large scatter that cannot be explained by variations in R V or by the Goobar power-law for circumstellar dust, but rather is correlated with spectroscopic features of the supernova and is therefore likely due to metallicity effects.

To present a case of a vital ectopic pregnancy after 8 weeks that was located in the right ovary. Case study and literature review. Hospital outpatient clinic. A 29-year-old primigravida presented with lower abdominal pain and mild vaginal bleeding at 8 weeks after her last menstrual period. Wedge resection of the ovary which did not affect subsequent fertility. Conservative treatment options and preservation of patient's reproductive capacity. The embryo was laparoscopically removed in toto and visualized. Therefore, macroscopic correlation to Carnegie stage 16 of development was possible. Approximately 3% of all ectopic pregnancies are located in the ovaries. Preoperative diagnosis of this extremely rare condition is challenging, because the ectopic tumor often resembles cysts of the corpus luteum. At surgery, the trophoblast tissue or the embryo can rarely be visualized completely.

Integrated assessment of climate change

1994-01-01

Many researchers are working on all the separate parts of the climate problem. The objective of integrated assessment is to put the results from this work together in order to look carefully at the big picture so as to: (1) keep a proper sense of perspective about the problem, since climate change will occur in the presence of many other natural and human changes; (2) develop the understanding necessary to support informed decision making by many different key public and private actors around the world; and (3) assure that the type and mix of climate-related research that is undertaken will be as useful as possible to decisions makers in both the near and long term. This paper outlines a set of design guidelines for formulating integrated assessment programs and projects and then outlines some of the current problems and opportunities. Selected points are illustrated by drawing on results from the integrated assessment research now in progress at Carnegie Mellon University

Alpha: A real-time decentralized operating system for mission-oriented system integration and operation

Science.gov (United States)

Jensen, E. Douglas

1988-01-01

Alpha is a new kind of operating system that is unique in two highly significant ways. First, it is decentralized transparently providing reliable resource management across physically dispersed nodes, so that distributed applications programming can be done largely as though it were centralized. And second, it provides comprehensive, high technology support for real-time system integration and operation, an application area which consists predominately of aperiodic activities having critical time constraints such as deadlines. Alpha is extremely adaptable so that it can be easily optimized for a wide range of problem-specific functionality, performance, and cost. Alpha is the first systems effort of the Archons Project, and the prototype was created at Carnegie-Mellon University directly on modified Sun multiprocessor workstation hardware. It has been demonstrated with a real-time C(sup 2) application. Continuing research is leading to a series of enhanced follow-ons to Alpha; these are portable but initially hosted on Concurrent's MASSCOMP line of multiprocessor products.

The spin rotation parameters A and R were measured for the elastic pion-proton scattering by the PNPI-ITEP collaboration in the D/sub 13 /(1700) resonance region. The main goal of the experimental program is to resolve the current partial-wave analyses (PWA) uncertainties. Simultaneously with A and R the polarization parameter P was measured with the purpose to improve the experimental database and estimate systematic errors. The constraint which demands a smooth energy dependence of all pi /sup -/p transverse amplitude zeros in the complex plane together with the new experimental data on the A parameter can lead to the conclusion that the Barrelet branch of "zero trajectories" is chosen improperly in PWA of the Carnegie- Mellon-Lawrence-Berkeley-Laboratory groups at the range of the pion beam momentum near 1.0 GeV/c. The setup included a longitudinally polarized proton target with superconductive magnet, multiwire spark chambers and carbon polarimeter with thick filter. The experiment was performed at the IT...

For the past dozen years, 500- and 600-MHz spectrometers have become available in many laboratories. The first 600-MHz NMR spectrometer (at Carnegie Mellon University) was commissioned more than 15 years ago and, until 1994, represented the highest field available for high-resolution NMR. This year, we have witnessed unprecedented progress in the development of very high field magnets for NMR spectroscopy, including the delivery of the first commercial 750-MHz NMR spectrometers. In addition, NMR signals have been obtained from 20-Tesla magnets (850 MHz for {sup 1}H`s) at both Los Alamos National Laboratory and Florida State University in the NHMFL (National High Magnetic Field Laboratory). These preliminary experiments have been performed in magnets with 100-ppm homogeneity, but a 20-Tesla magnet developed for the NHMFL will be brought to field this year with a projected homogeneity of 0.1 ppm over a 1-cm-diam spherical volume.

This report describes the technical progress made on the Pittsburgh Air Quality Study (PAQS) during the period of August 2001 through January of 2002. The major activity during this project period was the continuation of the ambient monitoring effort. Work also progressed on organizing the upcoming source characterization effort, and there was continued development of several three-dimensional air quality models. The first PAQS data analysis workshop for the project was held at Carnegie Mellon in December 2001. Two new instruments were added to site during this project period: a single particle mass spectrometer and an in situ VOC instrument. The single particle mass spectrometer has been deployed since the middle of September and has collected more than 150 days of data. The VOC instrument was only deployed during the intensive sampling period. Several instruments experienced operational issues during this project period. The overall data recovery rate for the project has been high

Radiation damage study for silicon calorimetry: Summary of first year's activity

International Nuclear Information System (INIS)

Russ, J.S.

1988-01-01

In the first contract year of this activity at Carnegie-Mellon we have had two major objectives. These were to devise and test a non-intrusive means to measure the energy and spatial profiles of the neutrons generated in a hadronic cascade at high energy; and to study the calibration systematics of silicon diode detectors as a prelude to their evaluation for SSC calorimetry. These objectives have been carried out, as are described in this paper. In addition we have recoded the ORNL detector simulation program HETC to operate on a VAX and are working on the conversion of the low energy neutron transport program MORSE. These programs are used heavily at Oak Ridge (Gabriel and coworkers) for cascade studies. For silicon calorimetry one wants to have more control over the energy deposition routines, especially in MORSE. Unfortunately, MORSE is heavily-laden with machine code, and its conversion is going slowly. 11 refs., 5 figs

RedZone Robotics, Inc. and Carnegie Mellon University's Field Robotics Center have undertaken a contract to develop a next-generation worksystem for decommissioning and dismantlement tasks in Department of Energy (DOE) facilities. Currently, the authors are closing the second phase of this three phase effort and have completed the design and fabrication of the worksystem: Rosie. Rosie includes a locomotor, heavy manipulator, control center, and control system for robot operation. The locomotor is an omni-directional platform with tether management and hydraulic power capabilities. The heavy manipulator is a high-payload, long-reach system intended to deploy tools into the work area. The heavy manipulator is capable of deploying systems such as the Dual-Arm Work Module--a five degree-of-freedom platform supporting two highly dexterous manipulators--or a single manipulator for performing simpler, less dexterous tasks. Rosie is telerobotic to the point of having servo-controlled motions which can be operated and coordinated through the control center

Gendron, Gerald; Roberts, David; Poole, Donold; Aquino, Anna

2012-01-01

This paper proposes a cyber security modeling and simulation roadmap to enhance mission assurance governance and establish risk reduction processes within constrained budgets. The term mission assurance stems from risk management work by Carnegie Mellon's Software Engineering Institute in the late 19905. By 2010, the Defense Information Systems Agency revised its cyber strategy and established the Program Executive Officer-Mission Assurance. This highlights a shift from simply protecting data to balancing risk and begins a necessary dialogue to establish a cyber security roadmap. The Military Operations Research Society has recommended a cyber community of practice, recognizing there are too few professionals having both cyber and analytic experience. The authors characterize the limited body of knowledge in this symbiotic relationship. This paper identifies operational and research requirements for mission assurance M&S supporting defense and homeland security. M&S techniques are needed for enterprise oversight of cyber investments, test and evaluation, policy, training, and analysis.

We describe and employ a stacking procedure to investigate abundances derived from the low signal-to-noise ratio spectra obtained in the Carnegie RR Lyrae Survey (CARRS). We find iron metallicities that extend from [Fe/H] ∼ ‑2.5 to values at least as large as [Fe/H] ∼ ‑0.5 in the 274-spectrum CARRS RRc data set. We consider RRc sample contamination by high amplitude solar metallicity δ Scuti stars (HADS) at periods less than 0.3 days, where photometric discrimination between RRc and δ Scuti stars has proven to be problematic. We offer a spectroscopic discriminant, the well-marked overabundance of heavy elements, principally [Ba/H], that is a common, if not universal, characteristic of HADS of all periods and axial rotations. No bona fide RRc stars known to us have verified heavy-element overabundances. Three out of 34 stars in our sample with [Fe/H] > ‑0.7 exhibit anomalously strong features of Sr, Y, Zr, Ba, and many rare earths. However, carbon is not enhanced in these three stars, and we conclude that their elevated n-capture abundances have not been generated in interior neutron-capture nucleosynthesis. Contamination by HADS appears to be unimportant, and metal-rich RRc stars occur in approximately the same proportion in the Galactic field as do metal-rich RRab stars. An apparent dearth of metal-rich RRc is probably a statistical fluke. Finally, we show that RRc stars have a similar inverse period–metallicity relationship as has been found for RRab stars.

We present an updated analysis of the intrinsic colors of Type Ia supernova (SNe Ia) using the latest data release of the Carnegie Supernova Project. We introduce a new light-curve parameter very similar to stretch that is better suited for fast-declining events, and find that these peculiar types can be seen as extensions to the population of 'normal' SNe Ia. With a larger number of objects, an updated fit to the Lira relation is presented along with evidence for a dependence on the late-time slope of the B – V light-curves with stretch and color. Using the full wavelength range from u to H band, we place constraints on the reddening law for the sample as a whole and also for individual events/hosts based solely on the observed colors. The photometric data continue to favor low values of R{sub V} , though with large variations from event to event, indicating an intrinsic distribution. We confirm the findings of other groups that there appears to be a correlation between the derived reddening law, R{sub V} , and the color excess, E(B – V), such that larger E(B – V) tends to favor lower R{sub V} . The intrinsic u-band colors show a relatively large scatter that cannot be explained by variations in R{sub V} or by the Goobar power-law for circumstellar dust, but rather is correlated with spectroscopic features of the supernova and is therefore likely due to metallicity effects.

Reliable age determination of first-trimester human embryos and fetuses is an important parameter for clinical use and basic science. Age determination by ultrasound or morphometric parameters of embryos 4-6 weeks post conception (p.c.) have been questioned, and more accurate methods are required. Data on whether and how maternal smoking and alcohol consumption influence embryonic and fetal foot growth is also lacking. Embryonic tissue from 102 first-trimester legal abortions (aged 35-69 days p.c.) were collected. All women answered a questionnaire concerning smoking and drinking habits, and delivered a urine sample for cotinine analysis. Embryonic age was evaluated by vaginal ultrasound measurements and by post-termination foot length and compared with the Carnegie stages. Foot bud and foot plate were defined and measured as foot length in embryos aged 35-47 days p.c. (range 0.8-2.1 mm). In embryos and fetuses aged 41-69 days p.c., heel-toe length was measured (range 2.5-7.5 mm). We found a significant linear correlation between foot length and age. Morphology of the feet was compared visually with the Carnegie collection, and we found that the mean ages of the two collections correlated well. Foot length was independent of gender, Environmental Tobacco Smoke, maternal smoking and alcohol consumption. Foot length correlated linearly to embryonic and foetal age, and was unaffected by gender, ETS, maternal smoking and alcohol consumption.

Preparing Planetary Scientists to Engage Audiences

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.

Code of conduct for scientists (abstract)

International Nuclear Information System (INIS)

Khurshid, S.J.

2011-01-01

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

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

2016-01-01

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

Marketing for scientists

CERN Document Server

Kuchner, Marc J

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...

Scientists Like Me: Faces of Discovery

Enevoldsen, A. A. G.; Culp, S.; Trinh, A.

2010-08-01

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

There can be multiple benefits of scientists engaging with young people, including motivation and inspiration for all involved.

Professional Ethics for Climate Scientists

Science.gov (United States)

Peacock, K.; Mann, M. E.

2014-12-01

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

Gifted and Talented Students’ Images of Scientists

Directory of Open Access Journals (Sweden)

Sezen Camcı-Erdoğan

2013-06-01

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.

The physician-scientists: rare species in Africa.

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.

This is the first release of optical spectroscopic data of low-redshift Type Ia supernovae (SNe Ia) by the Carnegie Supernova Project including 604 previously unpublished spectra of 93 SNe Ia. The observations cover a range of phases from 12 days before to over 150 days after the time of B-band maximum light. With the addition of 228 near-maximum spectra from the literature, we study the diversity among SNe Ia in a quantitative manner. For that purpose, spectroscopic parameters are employed such as expansion velocities from spectral line blueshifts and pseudo-equivalent widths (pW). The values of those parameters at maximum light are obtained for 78 objects, thus providing a characterization of SNe Ia that may help to improve our understanding of the properties of the exploding systems and the thermonuclear flame propagation. Two objects, namely, SNe 2005M and 2006is, stand out from the sample by showing peculiar Si II and S II velocities but otherwise standard velocities for the rest of the ions. We further study the correlations between spectroscopic and photometric parameters such as light-curve decline rate and color. In agreement with previous studies, we find that the pW of Si II absorption features are very good indicators of light-curve decline rate. Furthermore, we demonstrate that parameters such as pW2 (Si II 4130) and pW6 (Si II 5972) provide precise calibrations of the peak B-band luminosity with dispersions of ≈0.15 mag. In the search for a secondary parameter in the calibration of peak luminosity for SNe Ia, we find a ≈2σ-3σ correlation between B-band Hubble residuals and the velocity at maximum light of S II and Si II lines

Kourtidis, Konstantinos; Georgoulias, Aristeidis

2017-04-01

We studied the impact of anthropogenic aerosols, fine mode natural aerosols, Saharan dust, atmospheric water vapor, cloud fraction, cloud optical depth and cloud top height on the magnitude of fair weather PG at the rural station of Xanthi. Fair weather PG was measured in situ while the other parameters were obtained from the MODIS instrument onboard the Terra and Aqua satellites. All of the above parameteres were found to impact fair weather PG magnitude. Regarding aerosols, the impact was larger for Saharan dust and fine mode natural aerosols whereas regarding clouds the impact was larger for cloud fraction while less than that of aerosols. Water vapour and ice precipitable water were also found to influence fair weather PG. Since aerosols and water are ubiquitous in the atmosphere and exhibit large spatial and temporal variability, we postulate that our understanding of the Carnegie curve might need revision.

Observed Type II supernova colours from the Carnegie Supernova Project-I

We present a study of observed Type II supernova (SN II) colours using optical/near-infrared photometric data from the Carnegie Supernovae Project-I. We analyse four colours (B - V, u - g, g - r, and g - Y) and find that SN II colour curves can be described by two linear regimes during the photospheric phase. The first (s1, colour) is steeper and has a median duration of ˜40 d. The second, shallower slope (s2, colour) lasts until the end of the `plateau' (˜80 d). The two slopes correlate in the sense that steeper initial colour curves also imply steeper colour curves at later phases. As suggested by recent studies, SNe II form a continuous population of objects from the colour point of view as well. We investigate correlations between the observed colours and a range of photometric and spectroscopic parameters including the absolute magnitude, the V-band light-curve slopes, and metal-line strengths. We find that less luminous SNe II appear redder, a trend that we argue is not driven by uncorrected host-galaxy reddening. While there is significant dispersion, we find evidence that redder SNe II (mainly at early epochs) display stronger metal-line equivalent widths. Host-galaxy reddening does not appear to be a dominant parameter, neither driving observed trends nor dominating the dispersion in observed colours. Intrinsic SN II colours are most probably dominated by photospheric temperature differences, with progenitor metallicity possibly playing a minor role. Such temperature differences could be related to differences in progenitor radius, together with the presence or absence of circumstellar material close to the progenitor stars.

Do scientists trace hot topics?

2013-01-01

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

High formation of secondary organic aerosol from the photo-oxidation of toluene

Directory of Open Access Journals (Sweden)

L. Hildebrandt

2009-05-01

Full Text Available Toluene and other aromatics have long been viewed as the dominant anthropogenic secondary organic aerosol (SOA precursors, but the SOA mass yields from toluene reported in previous studies vary widely. Experiments conducted in the Carnegie Mellon University environmental chamber to study SOA formation from the photo-oxidation of toluene show significantly larger SOA production than parameterizations employed in current air-quality models. Aerosol mass yields depend on experimental conditions: yields are higher under higher UV intensity, under low-NO_x conditions and at lower temperatures. The extent of oxidation of the aerosol also varies with experimental conditions, consistent with ongoing, progressive photochemical aging of the toluene SOA. Measurements using a thermodenuder system suggest that the aerosol formed under high- and low-NO_x conditions is semi-volatile. These results suggest that SOA formation from toluene depends strongly on ambient conditions. An approximate parameterization is proposed for use in air-quality models until a more thorough treatment accounting for the dynamic nature of this system becomes available.

Implementation of a data fusion algorithm for RODS, a real-time outbreak and disease surveillance system.

Energy Technology Data Exchange (ETDEWEB)

2005-10-01

Due to the nature of many infectious agents, such as anthrax, symptoms may either take several days to manifest or resemble those of less serious illnesses leading to misdiagnosis. Thus, bioterrorism attacks that include the release of such agents are particularly dangerous and potentially deadly. For this reason, a system is needed for the quick and correct identification of disease outbreaks. The Real-time Outbreak Disease Surveillance System (RODS), initially developed by Carnegie Mellon University and the University of Pittsburgh, was created to meet this need. The RODS software implements different classifiers for pertinent health surveillance data in order to determine whether or not an outbreak has occurred. In an effort to improve the capability of RODS at detecting outbreaks, we incorporate a data fusion method. Data fusion is used to improve the results of a single classification by combining the output of multiple classifiers. This paper documents the first stages of the development of a data fusion system that can combine the output of the classifiers included in RODS.

As the three-year period FY93-FY96 ended, there were six senior investigators on the grant full-time: Bulgac, Henley, Miller, Savage, van Kolck and Wilets. This represents an increase of two members from the previous three-year period, achieved with only a two percent increase over the budget for FY90-FY93. In addition, the permanent staff of the Institute for Nuclear Theory (George Bertsch, Wick Haxton, and David Kaplan) continued to be intimately associated with our physics research efforts. Aurel Bulgac joined the Group in September, 1993 as an assistant professor, with promotion requested by the Department and College of Arts and Sciences by September, 1997. Martin Savage, who was at Carnegie-Mellon University, jointed the Physics Department in September, 1996. U. van Kolck continued as research assistant professor, and we were supporting one postdoctoral research associate, Vesteinn Thorssen, who joined us in September, 1995. Seven graduate students were being supported by the Grant (Chuan-Tsung Chan, Michael Fosmire, William Hazelton, Jon Karakowski, Jeffrey Thompson, James Walden and Mitchell Watrous)

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

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

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.

The Carnegie-Irvine Galaxy Survey. V. Statistical Study of Bars and Buckled Bars

Li, Zhao-Yu; Ho, Luis C.; Barth, Aaron J.

2017-08-01

Simulations have shown that bars are subject to a vertical buckling instability that transforms thin bars into boxy or peanut-shaped structures, but the physical conditions necessary for buckling to occur are not fully understood. We use the large sample of local disk galaxies in the Carnegie-Irvine Galaxy Survey to examine the incidence of bars and buckled bars across the Hubble sequence. Depending on the disk inclination angle (I), a buckled bar reveals itself as either a boxy/peanut-shaped bulge (at high I) or as a barlens structure (at low I). We visually identify bars, boxy/peanut-shaped bulges, and barlenses, and examine the dependence of bar and buckled bar fractions on host galaxy properties, including Hubble type, stellar mass, color, and gas mass fraction. We find that the barred and unbarred disks show similar distributions in these physical parameters. The bar fraction is higher (70%-80%) in late-type disks with low stellar mass (M * 1010.5 M ⊙), and decreases with higher gas mass ratio. These results suggest that bars are more difficult to grow in massive disks that are dynamically hotter than low-mass disks. However, once a bar forms, it can easily buckle in the massive disks, where a deeper potential can sustain the vertical resonant orbits. We also find a probable buckling bar candidate (ESO 506-G004) that could provide further clues to understand the timescale of the buckling process.

The Local-Cosmopolitan Scientist

Directory of Open Access Journals (Sweden)

Barney G. Glaser, Ph.D., Hon. Ph.D.

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.

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.

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...

The first phase of the Carnegie Supernova Project (CSP-I) was a dedicated supernova follow-up program based at the Las Campanas Observatory that collected science data of young, low-redshift supernovae between 2004 and 2009. Presented in this paper is the CSP-I photometric data release of low-redshift stripped-envelope core-collapse supernovae. The data consist of optical (uBgVri) photometry of 34 objects, with a subset of 26 having near-infrared (YJH) photometry. Twenty objects have optical pre-maximum coverage with a subset of 12 beginning at least five days prior to the epoch of B-band maximum brightness. In the near-infrared, 17 objects have pre-maximum observations with a subset of 14 beginning at least five days prior to the epoch of J-band maximum brightness. Analysis of this photometric data release is presented in companion papers focusing on techniques to estimate host-galaxy extinction and the light-curve and progenitor star properties of the sample. The analysis of an accompanying visual-wavelength spectroscopy sample of 150 spectra will be the subject of a future paper. Based on observations collected at Las Campanas Observatory.Tables 2-8 are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (http://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/609/A134

The Dilemma of Scientists in the Nuclear Age

International Nuclear Information System (INIS)

Broda, E.

1982-01-01

Scientists have made possible the nuclear arms race. The cases of some of the individual scientists are discussed. 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)

Scientists as role models in space science outreach

Science.gov (United States)

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.

Building the Next Generation of Earth Scientists: the Deep Carbon Observatory Early Career Scientist Workshops

Science.gov (United States)

Pratt, K.; Fellowes, J.; Giovannelli, D.; Stagno, V.

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.

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.

Improving Communication Skills in Early Career Scientists

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.

Scientists want more children.

Ecklund, Elaine Howard; Lincoln, Anne E

2011-01-01

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.

Scientists Involved in K-12 Education

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

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.

Increasing both the public health potential of basic research and the scientist satisfaction. An international survey of bio-scientists.

Science.gov (United States)

Sorrentino, Carmen; Boggio, Andrea; Confalonieri, Stefano; Hemenway, David; Scita, Giorgio; Ballabeni, Andrea

2016-01-01

Basic scientific research generates knowledge that has intrinsic value which is independent of future applications. Basic research may also lead to practical benefits, such as a new drug or diagnostic method. Building on our previous study of basic biomedical and biological researchers at Harvard, we present findings from a new survey of similar scientists from three countries. The goal of this study was to design policies to enhance both the public health potential and the work satisfaction and test scientists' attitudes towards these factors. The present survey asked about the scientists' motivations, goals and perspectives along with their attitudes concerning  policies designed to increase both the practical (i.e. public health) benefits of basic research as well as their own personal satisfaction. Close to 900 basic investigators responded to the survey; results corroborate the main findings from the previous survey of Harvard scientists. In addition, we find that most bioscientists disfavor present policies that require a discussion of the public health potential of their proposals in grants but generally favor softer policies aimed at increasing the quality of work and the potential practical benefits of basic research. In particular, bioscientists are generally supportive of those policies entailing the organization of more meetings between scientists and the general public, the organization of more academic discussion about the role of scientists in the society, and the implementation of a "basic bibliography" for each new approved drug.

Scientists, government, and nuclear power

Katz, J.E.

1982-01-01

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

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.

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.

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.

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.

Taking the Scientist's Perspective - The Nonfiction Narrative Engages Episodic Memory to Enhance Students' Understanding of Scientists and Their Practices

Science.gov (United States)

Larison, Karen D.

2018-03-01

The Next Generation Science Standards (NGSS Lead States 2013) mandates that schools provide students an understanding of the skills and knowledge that scientists use to engage in scientific practices. In this article, I argue that one of the best ways to accomplish this goal is to have students take the perspective of the scientist by reading nonfiction narratives written by scientists and science writers. I explore the anthropological and neurological evidence that suggests that perspective-taking is an essential component in the learning process. It has been shown that by around age 4, the human child begins to be able to take the perspective of others—a process that neuroscientists have shown engages episodic memory, a memory type that some neurocognitive scientists believe is central in organizing human cognition. Neuroscientists have shown that the brain regions in which episodic memory resides undergo pronounced anatomical changes during adolescence, suggesting that perspective-taking assumes an even greater role in cognition during adolescence and young adulthood. Moreover, I argue that the practice of science itself is narrative in nature. With each new observation and experiment, the scientist is acting to reveal an emerging story. It is the story-like nature of science that motivates the scientist to push onward with new experiments and new observations. It is also the story-like nature of the practice of science that can potentially engage the student. The classroom studies that I review here confirm the power of the narrative in increasing students' understanding of science.

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

The Carnegie-Irvine Galaxy Survey. V. Statistical Study of Bars and Buckled Bars

Simulations have shown that bars are subject to a vertical buckling instability that transforms thin bars into boxy or peanut-shaped structures, but the physical conditions necessary for buckling to occur are not fully understood. We use the large sample of local disk galaxies in the Carnegie-Irvine Galaxy Survey to examine the incidence of bars and buckled bars across the Hubble sequence. Depending on the disk inclination angle ( i ), a buckled bar reveals itself as either a boxy/peanut-shaped bulge (at high i ) or as a barlens structure (at low i ). We visually identify bars, boxy/peanut-shaped bulges, and barlenses, and examine the dependence of bar and buckled bar fractions on host galaxy properties, including Hubble type, stellar mass, color, and gas mass fraction. We find that the barred and unbarred disks show similar distributions in these physical parameters. The bar fraction is higher (70%–80%) in late-type disks with low stellar mass ( M {sub *} < 10{sup 10.5} M {sub ⊙}) and high gas mass ratio. In contrast, the buckled bar fraction increases to 80% toward massive and early-type disks ( M {sub *} > 10{sup 10.5} M {sub ⊙}), and decreases with higher gas mass ratio. These results suggest that bars are more difficult to grow in massive disks that are dynamically hotter than low-mass disks. However, once a bar forms, it can easily buckle in the massive disks, where a deeper potential can sustain the vertical resonant orbits. We also find a probable buckling bar candidate (ESO 506−G004) that could provide further clues to understand the timescale of the buckling process.

Continuous Risk Management at NASA

Science.gov (United States)

Hammer, Theodore F.; Rosenberg, Linda

1999-01-01

NPG 7120.5A, "NASA Program and Project Management Processes and Requirements" enacted in April, 1998, requires that "The program or project manager shall apply risk management principles..." The Software Assurance Technology Center (SATC) at NASA GSFC has been tasked with the responsibility for developing and teaching a systems level course for risk management that provides information on how to comply with this edict. The course was developed in conjunction with the Software Engineering Institute at Carnegie Mellon University, then tailored to the NASA systems community. This presentation will briefly discuss the six functions for risk management: (1) Identify the risks in a specific format; (2) Analyze the risk probability, impact/severity, and timeframe; (3) Plan the approach; (4) Track the risk through data compilation and analysis; (5) Control and monitor the risk; (6) Communicate and document the process and decisions. This risk management structure of functions has been taught to projects at all NASA Centers and is being successfully implemented on many projects. This presentation will give project managers the information they need to understand if risk management is to be effectively implemented on their projects at a cost they can afford.

Nuclear research with heavy ions. Annual progress report, January 1, 1979-December 31, 1979

International Nuclear Information System (INIS)

Kaplan, M.

1979-10-01

The experimental research emphasizes the detection and measurement of light charged particles emitted in reactions between heavy ions and complex nuclei. The program involves a collaboration between Carnegie-Mellon University and SUNY at Stony Brook, and utilizes the SuperHILAC and 88'' cyclotron accelerator facilities of the Lawrence Berkeley Laboratory. Correlations between light charged particles and heavy fragments provide detailed insights into the dynamics of the reaction mechanism. The light charged particles evaporated from fully accelerated fragments yield information on the excitation energies and spins of the equilibrated reaction products, whereas those particles that are emitted prior to thermal equilibration give a view of the early stages of the reaction. Experimental results of fusion and charged particle emission cross sections are discussed for a variety of heavy ion reactions, particularly those induced by 40 Ar ions. The theoretical development of the statistical model as applied to particle evaporation is reviewed, and semiempirical methods for facilitating comparisons with experimental data are presented. Current results from singles and coincidence experiments are given in detail for reactions of 340-MeV 40 Ar with Au, and analyses of average spins and energy sharing among particles are discussed

Performance Issues in High Performance Fortran Implementations of Sensor-Based Applications

Directory of Open Access Journals (Sweden)

David R. O'hallaron

1997-01-01

Full Text Available Applications that get their inputs from sensors are an important and often overlooked application domain for High Performance Fortran (HPF. Such sensor-based applications typically perform regular operations on dense arrays, and often have latency and through put requirements that can only be achieved with parallel machines. This article describes a study of sensor-based applications, including the fast Fourier transform, synthetic aperture radar imaging, narrowband tracking radar processing, multibaseline stereo imaging, and medical magnetic resonance imaging. The applications are written in a dialect of HPF developed at Carnegie Mellon, and are compiled by the Fx compiler for the Intel Paragon. The main results of the study are that (1 it is possible to realize good performance for realistic sensor-based applications written in HPF and (2 the performance of the applications is determined by the performance of three core operations: independent loops (i.e., loops with no dependences between iterations, reductions, and index permutations. The article discusses the implications for HPF implementations and introduces some simple tests that implementers and users can use to measure the efficiency of the loops, reductions, and index permutations generated by an HPF compiler.

Dynamic cyclical comovements of oil prices with industrial production, consumer prices, unemployment, and stock prices

International Nuclear Information System (INIS)

Ewing, Bradley T.; Thompson, Mark A.

2007-01-01

This paper examines the empirical relationship between oil prices and several key macroeconomic variables. In particular, we investigate the cyclical comovements of crude oil prices with output, consumer prices, unemployment, and stock prices. The methodology involves the use of the Hodrick-Prescott [Hodrick, R.J., Prescott, E.C., 1980. Post-War US Business Cycles: An Empirical Investigation. Working Paper, Carnegie Mellon University] and Baxter-King [Baxter, M., King, R.G., 1999. Measuring business cycles: approximate band-pass filters for economic time series. Review of Economics and Statistics 81, 575-593] filters, as well as the recently developed full-sample asymmetric Christiano-Fitzgerald [Christiano, L.J., Fitzgerald, T.J., 2003. The band pass filter. International Economic Review 44, 435-465] band-pass filter. Contemporaneous and cross-correlation estimates are made using the stationary cyclical components of the time series to make inference about the degree to which oil prices move with the cycle. Besides documenting a number of important cyclical relationships using three different time series filtering methods, the results suggest that crude oil prices are procyclical and lag industrial production. Additionally, we find that oil prices lead consumer prices. (author)

Rosie: A mobile workstation for decontamination and dismantlement operations

International Nuclear Information System (INIS)

1994-01-01

RedZone Robotics, Inc. and Carnegie Mellon University's Field Robotics Center have undertaken a contract to develop a next-generation worksystem for decommissioning and dismantlement tasks in Department of Energy (DOE) facilities. Currently, the authors are in the second phase of this three phase effort and are completing the design of the worksystem. Within this project RedZone is designing and fabricating a worksystem: Rosie. Rosie will include a locomotor, heavy manipulator, control center, and control system for robot operation. The locomotor is an omni-directional platform with tether management and hydraulic power capabilities. The heavy manipulator is a high-payload, long-reach system to deploy tools into the work area. The heavy manipulator will be capable of deploying systems such as the Dual-Arm Work Module--a five degree-of-freedom platform supporting two highly dexterous manipulators--or a single manipulator for performing simpler, less dexterous tasks. Rosie will be telerobotic to the point of having servo-controlled motions which can be operated and coordinated through the control center. This report describes the design of the systems. In phase three Rosie will be radiation-hardened and perform a demonstration in a contaminated facility

Teaching technological innovation and entrepreneurship in polymeric biomaterials.

Washburn, Newell R

2011-01-01

A model for incorporating an entrepreneurship module has been developed in an upper-division and graduate-level engineering elective on Polymeric Biomaterials (27-311/42-311/27-711/42-711) at Carnegie Mellon University. A combination of lectures, assignments, and a team-based project were used to provide students with a framework for applying their technical skills in the development of new technologies and a basic understanding of the issues related to translational research and technology commercialization. The specific approach to the project established in the course, which represented 20% of the students' grades, and the grading rubric for each of the milestones are described along with suggestions for generalizing this approach to different applications of biomaterials or other engineering electives. Incorporating this model of entrepreneurship into electives teaches students course content within the framework of technological innovation and many of the concepts and tools need to practice it. For students with situational or individual interest in the project, it would also serve to deepen their understanding of the traditional course components as well as provide a foundation for integrating technological innovation and lifelong learning.

Houdini: Reconfigurable in-tank robot

Energy Technology Data Exchange (ETDEWEB)

White, D.W.; Slifko, A.D.; Thompson, B.R. [RedZone Robotics, Inc., Pittsburgh, PA (United States)] [and others

1995-10-01

RedZone Robotics, Inc. and Carnegie Mellon University (CMU) are developing a tethered mobile robot, Houdini, to work inside waste storage tanks in support of the Department of Energy`s Environmental Restoration and Waste Management (EM) Program. This project is funded by the DOE`s Environmental Management Office of Technology Development through the Morgantown Energy Technology Center (METC). Our goal is to develop technology that is useful for in-tank operations throughout the DOE`s EM program. The first application of the Houdini system is to support the waste retrieval action planned for the final remediation of the Fernald site`s waste silos. RedZone and CMU have discussed potential applications for the system with personnel from several other DOE sites, and have found that the system would be widely useful in the DOE complex for tasks both inside and outside of waste storage tanks. We are tailoring the first implementation of the Houdini system to the specific needs of the Fernald silo remediation. The Fernald application-specific design constraints are primarily interface issues and should not interfere with the utility of the system at other sites.

Exploring the potential of using stories about diverse scientists and reflective activities to enrich primary students' images of scientists and scientific work

Science.gov (United States)

Sharkawy, Azza

2012-06-01

The purpose of this qualitative study was to explore the potential of using stories about diverse scientists to broaden primary students' images of scientists and scientific work. Stories featuring scientists from diverse socio-cultural backgrounds (i.e., physical ability, gender, ethnicity) were presented to 11 grade one students over a 15 -week period. My analysis of pre-and post audio-taped interview transcripts, draw-a-scientist-tests (Chambers 1983), participant observations and student work suggest that the stories about scientists and follow-up reflective activities provided resources for students that helped them: (a) acquire images of scientists from less dominant socio-cultural backgrounds; (b) enrich their views of scientific work from predominantly hands-on/activity-oriented views to ones that includes cognitive and positive affective dimensions. One of the limitations of using stories as a tool to extend students' thinking about science is highlighted in a case study of a student who expresses resistance to some of the counter-stereotypic images presented in the stories. I also present two additional case studies that illustrate how shifts in student' views of the nature of scientific work can change their interest in future participation in scientific work.

Scientist's Perceptions of Uncertainty During Discussions of Global Climate

Romanello, S.; Fortner, R.; Dervin, B.

2003-04-01

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

Increasing retention of early career female atmospheric scientists

2010-12-01

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 uses a multi-faceted approach to provide junior scientists with tools that will help them meet the challenges in their research and teaching career paths and will promote their retention in the field. 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 and prepared to fill vacancies created by the “baby boomer” retirees. 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. Post-workshop reunion events are held at national scientific meetings to maintain connectivity among each year’s participants, and for collaborating among participants of all workshops held to date. Evaluations of the two workshop cohorts thus far conclude that the workshops have been successful in achieving the goals of 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.

Science experiences of citizen scientists in entomology research

Science.gov (United States)

Lynch, Louise I.

Citizen science is an increasingly popular collaboration between members of the public and the scientific community to pursue current research questions. In addition to providing researchers with much needed volunteer support, it is a unique and promising form of informal science education that can counter declining public science literacy, including attitudes towards and understanding of science. However, the impacts of citizen science programs on participants' science literacy remains elusive. The purpose of this study was to balance the top-down approach to citizen science research by exploring how adult citizen scientists participate in entomology research based on their perceptions and pioneer mixed methods research to investigate and explain the impacts of citizen science programs. Transference, in which citizen scientists transfer program impacts to people around them, was uncovered in a grounded theory study focused on adults in a collaborative bumble bee research program. Most of the citizen scientists involved in entomology research shared their science experiences and knowledge with people around them. In certain cases, expertise was attributed to the individual by others. Citizen scientists then have the opportunity to acquire the role of expert to those around them and influence knowledge, attitudinal and behavioral changes in others. An intervention explanatory sequential mixed methods design assessed how entomology-based contributory citizen science affects science self-efficacy, self-efficacy for environmental action, nature relatedness and attitude towards insects in adults. However, no statistically significant impacts were evident. A qualitative follow-up uncovered a discrepancy between statistically measured changes and perceived influences reported by citizen scientists. The results have important implications for understanding how citizen scientists learn, the role of citizen scientists in entomology research, the broader program impacts and

Science Teachers' Views and Stereotypes of Religion, Scientists and Scientific Research: A call for scientist-science teacher partnerships to promote inquiry-based learning

Mansour, Nasser

2015-07-01

Despite a growing consensus regarding the value of inquiry-based learning (IBL) for students' learning and engagement in the science classroom, the implementation of such practices continues to be a challenge. If science teachers are to use IBL to develop students' inquiry practices and encourage them to think and act as scientists, a better understanding of factors that influence their attitudes towards scientific research and scientists' practices is very much needed. Within this context there is a need to re-examine the science teachers' views of scientists and the cultural factors that might have an impact on teachers' views and pedagogical practices. A diverse group of Egyptian science teachers took part in a quantitative-qualitative study using a questionnaire and in-depth interviews to explore their views of scientists and scientific research, and to understand how they negotiated their views of scientists and scientific research in the classroom, and how these views informed their practices of using inquiry in the classroom. The findings highlighted how the teachers' cultural beliefs and views of scientists and scientific research had constructed idiosyncratic pedagogical views and practices. The study suggested implications for further research and argued for teacher professional development based on partnerships with scientists.

The Normative Orientations of Climate Scientists.

Science.gov (United States)

Bray, Dennis; von Storch, Hans

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.

Scientists warn DOE of dwindling funding

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

Professional identity in clinician-scientists: brokers between care and science.

Science.gov (United States)

Kluijtmans, Manon; de Haan, Else; Akkerman, Sanne; van Tartwijk, Jan

2017-06-01

Despite increasing numbers of publications, science often fails to significantly improve patient care. Clinician-scientists, professionals who combine care and research activities, play an important role in helping to solve this problem. However, despite the ascribed advantages of connecting scientific knowledge and inquiry with health care, clinician-scientists are scarce, especially amongst non-physicians. The education of clinician-scientists can be complex because they must form professional identities at the intersection of care and research. The successful education of clinician-scientists requires insight into how these professionals view their professional identity and how they combine distinct practices. This study sought to investigate how recently trained nurse- and physiotherapist-scientists perceive their professional identities and experience the crossing of boundaries between care and research. Semi-structured interviews were conducted with 14 nurse- and physiotherapist-scientists at 1 year after they had completed MSc research training. Interviews were thematically analysed using insights from the theoretical frameworks of dialogical self theory and boundary crossing. After research training, the initial professional identity, of clinician, remained important for novice clinician-scientists, whereas the scientist identity was experienced as additional and complementary. A meta-identity as broker, referred to as a 'bridge builder', seemed to mediate competing demands or tensions between the two positions. Obtaining and maintaining a dual work position were experienced as logistically demanding; nevertheless, it was considered beneficial for crossing the boundaries between care and research because it led to reflection on the health profession, knowledge integration, inquiry and innovation in care, improved data collection, and research with a focus on clinical applicability. Novice clinician-scientists experience dual professional identities as care

A systematic identification and analysis of scientists on Twitter.

Full Text Available Metrics derived from Twitter and other social media-often referred to as altmetrics-are increasingly used to estimate the broader social impacts of scholarship. Such efforts, however, may produce highly misleading results, as the entities that participate in conversations about science on these platforms are largely unknown. For instance, if altmetric activities are generated mainly by scientists, does it really capture broader social impacts of science? Here we present a systematic approach to identifying and analyzing scientists on Twitter. Our method can identify scientists across many disciplines, without relying on external bibliographic data, and be easily adapted to identify other stakeholder groups in science. We investigate the demographics, sharing behaviors, and interconnectivity of the identified scientists. We find that Twitter has been employed by scholars across the disciplinary spectrum, with an over-representation of social and computer and information scientists; under-representation of mathematical, physical, and life scientists; and a better representation of women compared to scholarly publishing. Analysis of the sharing of URLs reveals a distinct imprint of scholarly sites, yet only a small fraction of shared URLs are science-related. We find an assortative mixing with respect to disciplines in the networks between scientists, suggesting the maintenance of disciplinary walls in social media. Our work contributes to the literature both methodologically and conceptually-we provide new methods for disambiguating and identifying particular actors on social media and describing the behaviors of scientists, thus providing foundational information for the construction and use of indicators on the basis of social media metrics.

For instance, if altmetric activities are generated mainly by scientists, does it really capture broader social impacts of science? Here we present a systematic approach to identifying and analyzing scientists on Twitter. Our method can identify scientists across many disciplines, without relying on external bibliographic data, and be easily adapted to identify other stakeholder groups in science. We investigate the demographics, sharing behaviors, and interconnectivity of the identified scientists. We find that Twitter has been employed by scholars across the disciplinary spectrum, with an over-representation of social and computer and information scientists; under-representation of mathematical, physical, and life scientists; and a better representation of women compared to scholarly publishing. Analysis of the sharing of URLs reveals a distinct imprint of scholarly sites, yet only a small fraction of shared URLs are science-related. We find an assortative mixing with respect to disciplines in the networks between scientists, suggesting the maintenance of disciplinary walls in social media. Our work contributes to the literature both methodologically and conceptually—we provide new methods for disambiguating and identifying particular actors on social media and describing the behaviors of scientists, thus providing foundational information for the construction and use of indicators on the basis of social media metrics.

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.

IC 1613 is an isolated dwarf galaxy within the Local Group. Low foreground and internal extinction, low metallicity, and low crowding make it an invaluable testbed for the calibration of the local distance ladder. We present new, high-fidelity distance estimates to IC 1613 via its Tip of the Red Giant Branch (TRGB) and its RR Lyrae (RRL) variables as part of the Carnegie-Chicago Hubble Program, which seeks an alternate local route to H 0 using Population II stars. We have measured a TRGB magnitude {I}{ACS}{TRGB}=20.35+/- {0.01}{stat}+/- {0.01}{sys} mag using wide-field observations obtained from the IMACS camera on the Magellan-Baade telescope. We have further constructed optical and near-infrared RRL light curves using archival BI- and new H-band observations from the ACS/WFC and WFC3/IR instruments on board the Hubble Space Telescope (HST). In advance of future Gaia data releases, we set provisional values for the TRGB luminosity via the Large Magellanic Cloud and Galactic RRL zero-points via HST parallaxes. We find corresponding true distance moduli {μ }0{TRGB}=24.30+/- {0.03}{stat}+/- {0.05}{sys} {mag} and =24.28+/- {0.04}{stat+{sys}} mag. We compare our results to a body of recent publications on IC 1613 and find no statistically significant difference between the distances derived from Population I and II stars. Based in part on observations made with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555. These observations are associated with programs #10505 and #13691. Additional observations are credited to the Observatories of the Carnegie Institution of Washington for the use of Magellan-Baade IMACS. Presented as part of a dissertation to the Department of Astronomy and Astrophysics, The University of Chicago, in partial fulfillment of the requirements for the Ph.D. degree.

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.

Women scientists generally play a great role in the public acceptance (PA) for the national policy of atomic energy developing in Japan. The reason may be that, when a woman scientist stands in the presence of women audience, she will be ready to be accepted by them as a person with the same gender, emotion and thought to themselves. A case of interchange between the Rokkasho women and the women scientists either resident at the nuclear site of Rokkasho or staying for a short time at Rokkasho by invitation has been described from the viewpoint of PA for the national policy of atomic energy developing, and more fundamentally, for promotion of science education.

The Carnegie Supernova Project (CSP) is designed to measure the luminosity distance for Type Ia supernovae (SNe Ia) as a function of redshift, and to set observational constraints on the dark energy contribution to the total energy content of the universe. The CSP differs from other projects to date in its goal of providing an I-band rest-frame Hubble diagram. Here, we present the first results from near-infrared observations obtained using the Magellan Baade telescope for SNe Ia with 0.1 m = 0.27 ± 0.02(statistical) and Ω DE = 0.76 ± 0.13(statistical) ± 0.09(systematic), for the matter and dark energy densities, respectively. If we parameterize the data in terms of an equation of state, w (with no time dependence), assume a flat geometry, and combine with baryon acoustic oscillations, we find that w = -1.05 ± 0.13(statistical) ± 0.09(systematic). The largest source of systematic uncertainty on w arises from uncertainties in the photometric calibration, signaling the importance of securing more accurate photometric calibrations for future supernova cosmology programs. Finally, we conclude that either the dust affecting the luminosities of SNe Ia has a different extinction law (R V = 1.8) than that in the Milky Way (where R V = 3.1), or that there is an additional intrinsic color term with luminosity for SNe Ia, independent of the decline rate. Understanding and disentangling these effects is critical for minimizing the systematic uncertainties in future SN Ia cosmology studies.

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.

From Local to EXtreme Environments (FLEXE) Student-Scientist Online Forums: hypothesis-based research examining ways to involve scientists in effective science education

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

Has ADVANCE Affected Senior Compared to Junior Women Scientists Differently?

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.

The mentoring of male and female scientists during their doctoral studies

Science.gov (United States)

Filippelli, Laura Ann

The mentoring relationships of male and female scientists during their doctoral studies were examined. Male and female biologists, chemists, engineers and physicists were compared regarding the importance of doctoral students receiving career enhancing and psychosocial mentoring from their doctoral chairperson and student colleagues. Scientists' satisfaction with their chairperson and colleagues as providers of these mentoring functions was also investigated. In addition, scientists identified individuals other than their chairperson and colleagues who were positive influencers on their professional development as scientists and those who hindered their development. A reliable instrument, "The Survey of Accomplished Scientists' Doctoral Experiences," was developed to assess career enhancing and psychosocial mentoring of doctoral chairpersons and student colleagues based on the review of literature, interviews with scientists and two pilot studies. Surveys were mailed to a total of 400 men and women scientists with earned doctorates, of which 209 were completed and returned. The findings reveal that female scientists considered the doctoral chairperson furnishing career enhancing mentoring more important than did the men, while both were in accordance with the importance of them providing psychosocial mentoring. In addition, female scientists were not as satisfied as men with their chairperson providing most of the career enhancing and psychosocial mentoring functions. For doctoral student colleagues, female scientists, when compared to men, indicated that they considered student colleagues more important in providing career enhancing and psychosocial mentoring. However, male and female scientists were equally satisfied with their colleagues as providers of these mentoring functions. Lastly, the majority of male scientists indicated that professors served as a positive influencer, while women revealed that spouses and friends positively influenced their professional

Phobias and underutilization of university scientists

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

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

The Scientist as Sentinel (Invited)

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.

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

Ernest Rutherford: scientist supreme

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)

Clinician-scientists in Canada: barriers to career entry and progress.

Directory of Open Access Journals (Sweden)

Bryn Lander

Full Text Available BACKGROUND: Clinician-scientists play an important role in translating between research and clinical practice. Significant concerns about a decline in their numbers have been raised. Potential barriers for career entry and progress are explored in this study. METHODS: Case-study research methods were used to identify barriers perceived by clinician-scientists and their research teams in two Canadian laboratories. These perceptions were then compared against statistical analysis of data from Canadian Institutes of Health Research (CIHR databases on grant and award performance of clinician-scientists and non-clinical PhDs for fiscal years 2000 to 2008. RESULTS: Three main barriers were identified through qualitative analysis: research training, research salaries, and research grants. We then looked for evidence of these barriers in the Canada-wide statistical dataset for our study period. Clinician-scientists had a small but statistically significant higher mean number of degrees (3.3 than non-clinical scientists (3.2, potentially confirming the perception of longer training times. But evidence of the other two barriers was equivocal. For example, while overall growth in salary awards was minimal, awards to clinician-scientists increased by 45% compared to 6.3% for non-clinical PhDs. Similarly, in terms of research funding, awards to clinician-scientists increased by more than 25% compared with 5% for non-clinical PhDs. However, clinician-scientist-led grants funded under CIHR's Clinical thematic area decreased significantly from 61% to 51% (p-value<0.001 suggesting that clinician-scientists may be shifting their attention to other research domains. CONCLUSION: While clinician-scientists continue to perceive barriers to career entry and progress, quantitative results suggest improvements over the last decade. Clinician-scientists are awarded an increasing proportion of CIHR research grants and salary awards. Given the translational importance of

To Boldly Go: Practical Career Advice for Young Scientists

Fiske, P.

1998-05-01

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.

Values in environmental research: Citizens’ views of scientists who acknowledge values

McCright, Aaron M.; Allen, Summer; Dietz, Thomas

2017-01-01

Scientists who perform environmental research on policy-relevant topics face challenges when communicating about how values may have influenced their research. This study examines how citizens view scientists who publicly acknowledge values. Specifically, we investigate whether it matters: if citizens share or oppose a scientist’s values, if a scientist’s conclusions seem contrary to or consistent with the scientist’s values, and if a scientist is assessing the state of the science or making a policy recommendation. We conducted two 3x2 factorial design online experiments. Experiment 1 featured a hypothetical scientist assessing the state of the science on the public-health effects of exposure to Bisphenol A (BPA), and Experiment 2 featured a scientist making a policy recommendation on use of BPA. We manipulated whether or not the scientist expressed values and whether the scientist’s conclusion appeared contrary to or consistent with the scientist’s values, and we accounted for whether or not subjects’ values aligned with the scientist’s values. We analyzed our data with ordinary least squares (OLS) regression techniques. Our results provide at least preliminary evidence that acknowledging values may reduce the perceived credibility of scientists within the general public, but this effect differs depending on whether scientists and citizens share values, whether scientists draw conclusions that run contrary to their values, and whether scientists make policy recommendations.

Challenges in translational research: the views of addiction scientists.

2014-01-01

To explore scientists' perspectives on the challenges and pressures of translating research findings into clinical practice and public health policy. We conducted semi-structured interviews with a purposive sample of 20 leading scientists engaged in genetic research on addiction. We asked participants for their views on how their own research translates, how genetic research addresses addiction as a public health problem and how it may affect the public's view of addiction. Most scientists described a direct translational route for their research, positing that their research will have significant societal benefits, leading to advances in treatment and novel prevention strategies. However, scientists also pointed to the inherent pressures they feel to quickly translate their research findings into actual clinical or public health use. They stressed the importance of allowing the scientific process to play out, voicing ambivalence about the recent push to speed translation. High expectations have been raised that biomedical science will lead to new prevention and treatment modalities, exerting pressure on scientists. Our data suggest that scientists feel caught in the push for immediate applications. This overemphasis on rapid translation can lead to technologies and applications being rushed into use without critical evaluation of ethical, policy, and social implications, and without balancing their value compared to public health policies and interventions currently in place.

Scientists as communicators: A randomized experiment to assess public reactions to scientists' social media communication along the science-advocacy continuum

Kotcher, J.; Vraga, E.; Myers, T.; Stenhouse, N.; Roser-Renouf, C.; Maibach, E.

2014-12-01

The question of what type of role scientists, or experts more generally, should play in policy debates is a perennial point of discussion within the scientific community. It is often thought that communication containing some form of policy advocacy is likely to compromise the perceived credibility of the individual scientist engaged in such behavior, with the possibility that it may also harm the credibility of the scientific community more broadly. Rather than evaluating statements in a binary fashion as representing either pure objectivity or pure advocacy, one recent model proposes that public communication by scientists should instead be thought of as falling along a continuum based upon the extent of normative judgment implicit in a statement. This approach predicts that as the extent of normative judgment increases, it poses a relatively greater risk to a scientist's perceived credibility. Though such a model is conceptually useful, little empirical social science research has systematically explored how individuals form judgments about different types of advocacy to examine common assumptions about the relative risks associated with such behaviors. In this presentation, we will report results from a national online experiment (N=1200) that examines audience responses to fictional social media posts written by either a climate scientist or a television weathercaster. Following the above model, the posts represent differing degrees of advocacy defined by the extent of normative judgment implicit in each statement. In instances where a specific policy is advocated, we examine whether participants' reactions are shaped by the extent to which the policy mentioned is congruent with one's political ideology. We hope this study will serve as an exemplar of applied science communication research that can begin to help inform scientists and other experts about the potential implications of different communication options they may choose from in deciding how to engage

Relations between scientists and government: the case of nuclear energy

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.

The past year has presented real challenges for scientists, especially in the US. The political context catalyzed the formation of many new organizations with a range of goals, from increasing the role of science in decision making to improving public trust in science and scientists. The grassroots organization 500 Women Scientists formed in the wake of the 2016 US election as a response to widespread anti-science, intolerant rhetoric and to form a community that could take action together. Within months, the network grew to more than 20,000 women scientists from across the globe. We evolved from our reactionary beginnings towards a broader mission to serve society by making science open, inclusive, and accessible. With the goal of transforming scientific institutions towards a more inclusive and just enterprise, we have been building alliances with diverse groups to provide training and mentorship opportunities to our members. In so doing, we created space for scientists from across disciplines to work together, speak out, and channel their energies toward making a difference. In partnership with the Union of Concerned Scientists and Rise Stronger, we assembled resources to help scientists write op-eds and letters to the editor about the importance of science in their communities. We partnered with researchers in Jordan to explore a new peer-to-peer mentoring model. Along with a healthcare advocacy group, we participated in dialogue to examine the role of science in affordable medicine. Finally, we are working with other groups to expand peer networks and career development resources for international STEM women. Our local chapters often initiate this work, teaming up with diverse organizations to bring science to their communities and, in the process, shift perceptions of what a scientist looks like. While as scientists, we would rather be conducting experiments or running models, what brings us together is an urgent sense that our scientific expertise is needed

Science Educational Outreach Programs That Benefit Students and Scientists.

Directory of Open Access Journals (Sweden)

Greg Clark

2016-02-01

Full Text Available Both scientists and the public would benefit from improved communication of basic scientific research and from integrating scientists into education outreach, but opportunities to support these efforts are limited. We have developed two low-cost programs--"Present Your PhD Thesis to a 12-Year-Old" and "Shadow a Scientist"--that combine training in science communication with outreach to area middle schools. We assessed the outcomes of these programs and found a 2-fold benefit: scientists improve their communication skills by explaining basic science research to a general audience, and students' enthusiasm for science and their scientific knowledge are increased. Here we present details about both programs, along with our assessment of them, and discuss the feasibility of exporting these programs to other universities.

Politics and scientific expertise: Scientists, risk perception, and nuclear waste policy

International Nuclear Information System (INIS)

Barke, R.P.; Jenkins-Smith, H.C.

1993-01-01

To study the homogeneity and influences on scientists' perspectives of environmental risks, the authors have examined similarities and differences in risk perceptions, particularly regarding nuclear wastes, and policy preferences among 1011 scientists and engineers. Significant differences (p<0.05) were found in the patterns of beliefs among scientists from different fields of research. In contrast to physicists, chemists, and engineers, life scientists tend to: (a) perceive the greatest risks from nuclear energy and nuclear waste management; (b) perceive higher levels of overall environmental risk; (c) strongly oppose imposing risks on unconsenting individuals; and (d) prefer stronger requirements for environmental management. On some issues related to priorities among public problems and calls for government action, there are significant variations among life scientists or physical scientists. It was also found that-independently of field of research-perceptions of risk and its correlates are significantly associated with the type of institution in which the scientist is employed. Scientists in universities or state and local governments tend to see the risks of nuclear energy and wastes as greater than scientists who work as business consultants, for federal organizations, or for private research laboratories. Significant differences also are found in priority given to environmental risks, the perceived proximity of environmental disaster, willingness to impose risks on an unconsenting population, and the necessity of accepting risks and sacrifices. 33 refs., 3 figs., 9 tabs

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.

A detailed view of Earth across space and time: our changing planet through a 32-year global Landsat and Sentinel-2 timelapse video

Herwig, C.

2017-12-01

The Landsat program offers an unparalleled record of our changing planet, with satellites that have been observing the Earth since 1972 to the present day. However, clouds, seasonal variation, and technical challenges around access to large volumes of data make it difficult for researchers and the public to understand global and regional scale changes across time through the planetary dataset. Earth Timelapse is a global, zoomable video that has helped revolutionize how users - millions of which have never been capable of utilizing Landsat data before - monitor and understand a changing planet. It is made from 33 cloud-free annual mosaics, one for each year from 1984 to 2016, which are made interactively explorable by Carnegie Mellon University CREATE Lab's Time Machine library, a technology for creating and viewing zoomable and pannable timelapses over space and time. Using Earth Engine, we combined over 5 million satellite images acquired over the past three decades by 5 different satellites. The majority of the images come from Landsat, a joint USGS/NASA Earth observation program that has observed the Earth since the 1970s. For 2015 and 2016, we combined Landsat 8 imagery with imagery from Sentinel-2A, part of the European Commission and European Space Agency's Copernicus Earth observation program. Along with the interactive desktop Timelapse application, we created a 200-video YouTube playlist highlighting areas across the world exhibiting change in the dataset.Earth Timelapse is an example that illustrates the power of Google Earth Engine's cloud-computing platform, which enables users such as scientists, researchers, and journalists to detect changes, map trends, and quantify differences on the Earth's surface using Google's computational infrastructure and the multi-petabyte Earth Engine data catalog. Earth Timelapse also highlights the value of data visualization to communicate with non-scientific audiences with varied technical and internet connectivity

Finding Meaningful Roles for Scientists in science Education Reform

Science.gov (United States)

Evans, Brenda

Successful efforts to achieve reform in science education require the active and purposeful engagement of professional scientists. Working as partners with teachers, school administrators, science educators, parents, and other stakeholders, scientists can make important contributions to the improvement of science teaching and learning in pre-college classrooms. The world of a practicing university, corporate, or government scientist may seem far removed from that of students in an elementary classroom. However, the science knowledge and understanding of all future scientists and scientifically literate citizens begin with their introduction to scientific concepts and phenomena in childhood and the early grades. Science education is the responsibility of the entire scientific community and is not solely the responsibility of teachers and other professional educators. Scientists can serve many roles in science education reform including the following: (1) Science Content Resource, (2) Career Role Model, (3) Interpreter of Science (4) Validator for the Importance of Learning Science and Mathematics, (5) Champion of Real World Connections and Value of Science, (6) Experience and Access to Funding Sources, (7) Link for Community and Business Support, (8) Political Supporter. Special programs have been developed to assist scientists and engineers to be effective partners and advocates of science education reform. We will discuss the rationale, organization, and results of some of these partnership development programs.

This study explores American and Greek primary pupils' visual images of scientists by means of two nonverbal data collection tasks to identify possible convergences and divergences. Specifically, it aims to investigate whether their images of scientists vary according to the data collection instrument used and to gender. To this end, 91 third-grade American ( N = 46) and Greek ( N = 45) pupils were examined. Data collection was conducted through a drawing task based on Chambers (1983) `Draw-A-Scientist-Test' (DAST) and a picture selection task during which the children selected between 14 pairs of illustrations those that were most probable to represent scientists. Analysis focused on stereotype indicators related with scientists' appearance and work setting. Results showed that the two groups' performance varied significantly across the tasks used to explore their stereotypic perceptions, although the overall stereotypy was not differentiated according to participants' ethnic group. Moreover, boys were found to use more stereotypic indicators than girls, while the picture selection task elicited more stereotypic responses than the drawing task. In general, data collected by the two instruments revealed convergences and divergences concerning the stereotypic indicators preferred. Similarities and differences between national groups point to the influence of a globalized popular culture on the one hand and of the different sociocultural contexts underlying science curricula and their implementation on the other. Implications for science education are discussed.

Poll of radiation health scientists

International Nuclear Information System (INIS)

Cohen, B.L.

1986-01-01

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

Scientists' perspectives on consent in the context of biobanking research.

Science.gov (United States)

Master, Zubin; Campo-Engelstein, Lisa; Caulfield, Timothy

2015-05-01

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.

2011-12-01

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.

Scientists and Science Education: Working at the Interface

Science.gov (United States)

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

Intra-professional dynamics in translational health research: the perspective of social scientists.

Science.gov (United States)

Currie, Graeme; El Enany, Nellie; Lockett, Andy

2014-08-01

In contrast to previous studies, which focus upon the professional dynamics of translational health research between clinician scientists and social scientists (inter-professional contestation), we focus upon contestation within social science (intra-professional contestation). Drawing on the empirical context of Collaborations for Leadership in Applied Health Research and Care (CLAHRCs) in England, we highlight that although social scientists accept subordination to clinician scientists, health services researchers attempt to enhance their position in translational health research vis-à-vis organisation scientists, whom they perceive as relative newcomers to the research domain. Health services researchers do so through privileging the practical impact of their research, compared to organisation scientists' orientation towards development of theory, which health services researchers argue is decoupled from any concern with healthcare improvement. The concern of health services researchers lies with maintaining existing patterns of resource allocation to support their research endeavours, working alongside clinician scientists, in translational health research. The response of organisation scientists is one that might be considered ambivalent, since, unlike health services researchers, they do not rely upon a close relationship with clinician scientists to carry out research, or more generally, garner resource.

2016-10-01

Many planetary scientists consider involvement in a robotic spacecraft mission the highlight of their career. We have searched for names of science team members and determined the percentage of women on each team. We have limited the lists to members working at US institutions at the time of selection. We also determined the year each team was selected. The gender of each team member was limited to male and female and based on gender expression. In some cases one of the authors knew the team member and what pronouns they use. In other cases, we based our determinations on the team member's name or photo (obtained via a google search, including institution). Our initial analysis considered 22 NASA planetary science missions over a period of 41 years and only considered NASA-selected PI and Co-Is and not participating scientists, postdocs, or graduate students. We found that there has been a dramatic increase in participation of women on spacecraft science teams since 1974, from 0-2% in the 1970s - 1980s to an average of 14% 2000-present. This, however, is still lower than the recent percentage of women in planetary science, which 3 different surveys found to be ~25%. Here we will present our latest results, which include consideration of participating scientists. As in the case of PIs and Co-Is, we consider only participating scientists working at US institutions at the time of their selection.

Scientists in an alternative vision of a globalized world

Science.gov (United States)

Erzan, Ayse

2008-03-01

Why should ``increasing the visibility of scientists in emergent countries'' be of interest? Can increasing the relevance and connectedness of scientific output, both to technological applications at home and cutting edge basic research abroad contribute to the general welfare in such countries? For this to happen, governments, inter-governmental and non-governmental organizations must provide incentives for the local industry to help fund and actively engage in the creation of new technologies, rather than settling for the solution of well understood engineering problems under the rubric of collaboration between scientists and industry. However, the trajectory of the highly industrialized countries cannot be retraced. Globalization facilitates closer interaction and collaboration between scientists but also deepens the contrasts between the center and the periphery, both world wide and within national borders; as it is understood today, it can lead to the redundancy of local technology oriented research, as the idea of a ``local industry'' is rapidly made obsolete. Scientists from all over the world are sucked into the vortex as both the economic and the cultural world increasingly revolve around a single axis. The challenge is to redefine our terms of reference under these rapidly changing boundary conditions and help bring human needs, human security and human happiness to the fore in elaborating and forging alternative visions of a globalized world. Both natural scientists and social scientists will be indispensable in such an endeavor.

The Immoral Landscape? Scientists Are Associated with Violations of Morality.

Science.gov (United States)

Rutjens, Bastiaan T; Heine, Steven J

2016-01-01

Do people think that scientists are bad people? Although surveys find that science is a highly respected profession, a growing discourse has emerged regarding how science is often judged negatively. We report ten studies (N = 2328) that investigated morality judgments of scientists and compared those with judgments of various control groups, including atheists. A persistent intuitive association between scientists and disturbing immoral conduct emerged for violations of the binding moral foundations, particularly when this pertained to violations of purity. However, there was no association in the context of the individualizing moral foundations related to fairness and care. Other evidence found that scientists were perceived as similar to others in their concerns with the individualizing moral foundations of fairness and care, yet as departing for all of the binding foundations of loyalty, authority, and purity. Furthermore, participants stereotyped scientists particularly as robot-like and lacking emotions, as well as valuing knowledge over morality and being potentially dangerous. The observed intuitive immorality associations are partially due to these explicit stereotypes but do not correlate with any perceived atheism. We conclude that scientists are perceived not as inherently immoral, but as capable of immoral conduct.

One More Legacy of Paul F. Brandwein: Creating Scientists

Fort, Deborah C.

2011-06-01

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

Science fiction by scientists an anthology of short stories

CERN Document Server

2017-01-01

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.

Caring for nanotechnology? Being an integrated social scientist.

Science.gov (United States)

Viseu, Ana

2015-10-01

One of the most significant shifts in science policy of the past three decades is a concern with extending scientific practice to include a role for 'society'. Recently, this has led to legislative calls for the integration of the social sciences and humanities in publicly funded research and development initiatives. In nanotechnology--integration's primary field site--this policy has institutionalized the practice of hiring social scientists in technical facilities. Increasingly mainstream, the workings and results of this integration mechanism remain understudied. In this article, I build upon my three-year experience as the in-house social scientist at the Cornell NanoScale Facility and the United States' National Nanotechnology Infrastructure Network to engage empirically and conceptually with this mode of governance in nanotechnology. From the vantage point of the integrated social scientist, I argue that in its current enactment, integration emerges as a particular kind of care work, with social scientists being fashioned as the main caretakers. Examining integration as a type of care practice and as a 'matter of care' allows me to highlight the often invisible, existential, epistemic, and affective costs of care as governance. Illuminating a framework where social scientists are called upon to observe but not disturb, to reify boundaries rather than blur them, this article serves as a word of caution against integration as a novel mode of governance that seemingly privileges situatedness, care, and entanglement, moving us toward an analytically skeptical (but not dismissive) perspective on integration.

Sky Fest: A Model of Successful Scientist Participation in E/PO

Participation in outreach events is an easy way for scientists to get involved with E/PO and reach many people with minimal time commitment. At the Lunar and Planetary Institute (LPI) in Houston, Texas, the E/PO team holds Sky Fest outreach events several times a year. These events each have a science content theme and include several activities for children and their parents, night sky viewing through telescopes, and scientist presentations. LPI scientists have the opportunity to participate in Sky Fest events either by helping lead an activity or by giving the scientist presentation (a short lecture and/or demonstration). Scientists are involved in at least one preparation meeting before the event. This allows them to ask questions, understand what activity they will be leading, and learn the key points that they should be sharing with the public, as well as techniques for effectively teaching members of the public about the event topic. During the event, each activity is run by one E/PO specialist and one scientist, enabling the scientist to learn about effective E/PO practices from the E/PO specialist and the E/PO specialist to get more science information about the event topic. E/PO specialists working together with scientists at stations provides a more complete, richer experience for event participants. Surveys of event participants have shown that interacting one-on-one with scientists is often one of their favorite parts of the events. Interviews with scientists indicated that they enjoyed Sky Fest because there was very little time involved on their parts outside of the actual event; the activities were created and/or chosen by the E/PO professionals, and setup for the events was completed before they arrived. They also enjoyed presenting their topic to people without a background in science, and who would not have otherwise sought out the information that was presented.

The Role of the Physician-Scientist in Our Evolving Society

The physician-scientist represents the medical-scientific version of the ?triple threat? athlete. Yet, in medicine as in sports, specialization and business are ever more in the forefront. As the field of medicine evolves, it is likely that the role of the physician, the scientist, and the physician-scientist will continue to change. Whether this is for the good or bad will only be known in hindsight.

Opportunities and Resources for Scientist Participation in Education and Public Outreach

2012-10-01

Active engagement of scientists in Education and Public Outreach (E/PO) activities results in benefits for both the audience and scientists. Most scientists are trained in research but have little formal training in education. The Planetary Science Education and Public Outreach (E/PO) Forum helps the Science Mission Directorate support scientists currently involved in E/PO and to help scientists who are interested in becoming involved in E/PO efforts find ways to do so through a variety of avenues. We will present current and future opportunities and resources for scientists to become engaged in education and public outreach. These include upcoming NASA SMD E/PO funding opportunities, professional development resources for writing NASA SMD E/PO proposals (webinars and other online tools), toolkits for scientists interested in best practices in E/PO (online guides for K-12 education and public outreach), EarthSpace (a community web space where instructors can find and share about teaching space and earth sciences in the undergraduate classroom, including class materials news and funding opportunities, and the latest education research), thematic resources for teaching about the solar system (archived resources from Year of the Solar System), and an online database of scientists interested in connecting with education programs.

Full Text Available This paper presents results of study on the characteristics of search activities, access to and use of information, and dissemination habits of researchers from scientific research institutes. From the methodological point of view, it is a mixed methods study which adopted the concurrent triangulation strategy. Data were collected through questionnaires, interviews and checklist, and then submitted to statistical and text analysis. The research sphere was consisted of researchers linked to the research units of the Ministry of Science, Technology and Innovation, and the sample basis were the researchers of the Brazilian Centre for Physics Research (CBPF and Museum of Astronomy and Related Sciences (MAST. Among other aspects, the findings shows that the safeguarded their disciplinary differences, search, access and communication activities, regardless of the knowledge area, occurring mainly in the digital environment; communication habits are stimulated by motives common to scientists and social scientists and humanists, share knowledge and visibility are the main reasons for the dissemination of research results, physicists are naturally within the open access context.

How scientists view the public, the media and the political process.

Besley, John C; Nisbet, Matthew

2013-08-01

We review past studies on how scientists view the public, the goals of communication, the performance and impacts of the media, and the role of the public in policy decision-making. We add to these past findings by analyzing two recent large-scale surveys of scientists in the UK and US. These analyses show that scientists believe the public is uninformed about science and therefore prone to errors in judgment and policy preferences. Scientists are critical of media coverage generally, yet they also tend to rate favorably their own experience dealing with journalists, believing that such interactions are important both for promoting science literacy and for career advancement. Scientists believe strongly that they should have a role in public debates and view policy-makers as the most important group with which to engage. Few scientists view their role as an enabler of direct public participation in decision-making through formats such as deliberative meetings, and do not believe there are personal benefits for investing in these activities. Implications for future research are discussed, in particular the need to examine how ideology and selective information sources shape scientists' views.

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)

Facilitating ethical reflection among scientists using the ethical matrix

DEFF Research Database (Denmark)

Jensen, Karsten Klint; Forsberg, Ellen-Marie; Gamborg, Christian

2011-01-01

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...

Full Text Available In biology textbooks and in lecture slides, it is customary to describe the significance of a historical scientific experiment alongside a still photograph of the scientist who performed the work.  This method communicates information about the scientists' works, but can be a dry method to describe an exciting and dynamic historical individual.  I have developed a method to animate still photographs and engravings of historical scientists and narrate them in the first person.  This method is rapid, inexpensive, and does not require more than average technical ability.  The animated historical scientists directly address the students to educate them about their own personal lives, struggles, and achievements.

Expediency of Study of the Scientists' Biographies in Physics Course

Full Text Available The aim of this article is a justification of the expediency of study of the scientists' biographies in physics course. Study of the biographic materials is one of the ways of motivation of learning and development of morality, humanity, internationalism. The selection criteria of biographic material have been allocated and method of study of the scientists' biographies has been described. Biographical data, scientific achievements and character traits are the components of “scientist's image”. Results proved that the use of the biographic materials raises the level of emotional component of learners' cognitive activity in physics teaching. Method of study of the scientists' biographies can be used in teaching of other school subjects.

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

The Carnegie Hubble Program (CHP) is designed to improve the extragalactic distance scale using data from the post-cryogenic era of Spitzer. The ultimate goal is a determination of the Hubble constant to an accuracy of 2%. This paper is the first in a series on the Cepheid population of the Large Magellanic Cloud, and focuses on the period-luminosity relations (Leavitt laws) that will be used, in conjunction with observations of Milky Way Cepheids, to set the slope and zero-point of the Cepheid distance scale in the mid-infrared. To this end, we have obtained uniformly-sampled light curves for 85 LMC Cepheids, having periods between 6 and 140 days. Period- luminosity and period-color relations are presented in the 3.6 micron and 4.5 micron bands. We demonstrate that the 3.6 micron band is a superb distance indicator. The cyclical variation of the [3.6]-[4.5] color has been measured for the first time. We attribute the amplitude and phase of the color curves to the dissociation and recombination of CO molecules in the Cepheid s atmosphere. The CO affects only the 4.5 micron flux making it a potential metallicity indicator.

We present final natural-system optical (ugriBV) and near-infrared (YJH) photometry of 134 supernovae (SNe) with probable white dwarf progenitors that were observed in 2004-2009 as part of the first stage of the Carnegie Supernova Project (CSP-I). The sample consists of 123 Type Ia SNe, 5 Type Iax SNe, 2 super-Chandrasekhar SN candidates, 2 Type Ia SNe interacting with circumstellar matter, and 2 SN 2006bt-like events. The redshifts of the objects range from z=0.0037 to 0.0835; the median redshift is 0.0241. For 120 (90%) of these SNe, near-infrared photometry was obtained. Average optical extinction coefficients and color terms are derived and demonstrated to be stable during the five CSP-I observing campaigns. Measurements of the CSP-I near-infrared bandpasses are also described, and near-infrared color terms are estimated through synthetic photometry of stellar atmosphere models. Optical and near-infrared magnitudes of local sequences of tertiary standard stars for each supernova are given, and a new calibration of Y-band magnitudes of the Persson et al. standards in the CSP-I natural system is presented.

Differential forms for scientists and engineers

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.

Scientists and Educators: Joining Forces to Enhance Ocean Science Literacy

Science.gov (United States)

Keener-Chavis, P.

2004-12-01

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

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.

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.

Interviewing German scientists on climate change. A preliminary study

Energy Technology Data Exchange (ETDEWEB)

Ungar, S. [GKSS-Forschungszentrum Geesthacht GmbH (Germany). Inst. fuer Kuestenforschung; Toronto Univ., Scarborough (Canada)

2004-07-01

This study is based on in-depth interviews with 25 German scientists at the Coastal Research Institute of the GKSS-Forschungszentrum. It takes as its context the differential rhetoric and planning on climate change found in Germany and North America. The interviews try to throw light on the early German decision to address climate change, and to assess the current attitudes, beliefs and experiences of these German scientists. The results reveal a degree of complacency among these scientists, including a sense that Germany is not particularly threatened by climate change and has the capacity to adapt to it. The scientists are critical of inaction among the German population, but themselves uphold a ''light version'' of the precautionary principle. They have great difficulty translating the idea of climate change into popular metaphors that can be grasped by children. They strongly reject any link between German leadership on the issue as a result of a sense of guilt about the German past. (orig.)

2011-01-01

Recent science of science research shows that scientific impact measures for journals and individual articles have quantifiable regularities across both time and discipline. However, little is known about the scientific impact distribution at the scale of an individual scientist. We analyze the aggregate production and impact using the rank-citation profile c(i)(r) of 200 distinguished professors and 100 assistant professors. For the entire range of paper rank r, we fit each c(i)(r) to a common distribution function. Since two scientists with equivalent Hirsch h-index can have significantly different c(i)(r) profiles, our results demonstrate the utility of the β(i) scaling parameter in conjunction with h(i) for quantifying individual publication impact. We show that the total number of citations C(i) tallied from a scientist's N(i) papers scales as [Formula: see text]. Such statistical regularities in the input-output patterns of scientists can be used as benchmarks for theoretical models of career progress.

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

Scientists' Views about Attribution of Global Warming

Verheggen, Bart; Strengers, Bart; Cook, John; van Dorland, Rob; Vringer, Kees; Peters, Jeroen; Visser, Hans; Meyer, Leo

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

The Pleistocene Eastern Equatorial Pacific: Insights from a New Carnegie Platform Stratigraphic Record

Science.gov (United States)

Gwizd, S.; Lea, D. W.

2016-12-01

Renewed interest in a classic Eastern Equatorial Pacific paleoceanographic site at 3° 35.85' S, 83° 57.79' W, previous site of cores V19-29 and TR163-31, prompted a re-coring in 2009 using the recently developed CDH giant piston coring system on cruise KNR195-5. Giant piston core CDH-36 (3225 m depth, 42.61 m length) nearly triples the length of previous cores at this site. When spliced together with companion multicore MC-34A (0.36 m length), these two cores generate continuous stratigraphy throughout most of the middle Pleistocene, and include recognized stratigraphic tie points ash layer "L" (Ninkovich and Shackleton, 1975) and the extinction of pink G. ruber. A new age model utilizing Bayesian analysis of 17 N. dutertrei radiocarbon dates in MC-34A and the top 3.4 m of CDH-36, and alignment of a new CDH-36 δ18O record with the LR04 benthic stack (Lisiecki and Raymo, 2005), demonstrates that this new "Carnegie Platform" (CP) record extends from 0 to 720 ka (MIS 18), tripling the timescale of previous studies, with an average sedimentation rate of 7 cm/kyr. The CP C. wuellerstorfi δ18O and δ13C records reveal strong consistencies in timing and extent of glacial and interglacial episodes with previously studied regional records. Coarse fraction percentage (%CF) ([coarse fraction/bulk dry sample] * 100) is also evaluated throughout the CP core in order to qualitatively assess dissolution cycles. The CP %CF dataset primarily records Pleistocene dissolution cycles, yet exhibits variability representative of potential local bathymetric and hydrographic effects. The timing of %CF cyclicity is consistent with processes which affect basin-wide calcium carbonate dissolution cycles, including changes in terrestrial carbon input to the oceans and changes in water mass ventilation (Shackleton, 1977; Toggweiler et al., 2006; Sexton and Barker, 2012). Establishing the stratigraphy of the CP record provides the first step towards a more thorough and extended analysis of

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

Bankston, Adriana; McDowell, Gary S.

2018-01-01

Being successful in an academic environment places many demands on junior scientists. Science communication currently may not be adequately valued and rewarded, and yet communication to multiple audiences is critical for ensuring that it remains a priority in today’s society. Due to the potential for science communication to produce better scientists, facilitate scientific progress, and influence decision-making at multiple levels, training junior scientists in both effective and ethical science communication practices is imperative, and can benefit scientists regardless of their chosen career path. However, many challenges exist in addressing specific aspects of this training. Principally, science communication training and resources should be made readily available to junior scientists at institutions, and there is a need to scale up existing science communication training programs and standardize core aspects of these programs across universities, while also allowing for experimentation with training. We propose a comprehensive core training program be adopted by universities, utilizing a centralized online resource with science communication information from multiple stakeholders. In addition, the culture of science must shift toward greater acceptance of science communication as an essential part of training. For this purpose, the science communication field itself needs to be developed, researched and better understood at multiple levels. Ultimately, this may result in a larger cultural change toward acceptance of professional development activities as valuable for training scientists. PMID:29904538

A model study, funded by the National Library of Medicine (NLM) and conducted by the Southeastern/Atlantic Regional Medical Library (RML) and the University of Maryland Health Sciences Library, attempted to assess the information needs of researchers in the developing field of biotechnology and to determine the resources available to meet those needs in major academic health sciences centers. Nine medical schools in RML Region 2 were selected to participate in a biotechnology awareness study. A survey was conducted of the nine medical school libraries to assess their support of biotechnology research. To identify the information needs of scientists engaged in biotechnology-related research at the schools, a written survey was sent to the deans of the nine institutions and selected scientists they had identified. This was followed by individual, in-depth interviews with both the deans and scientists surveyed. In general, scientists obtained information from three major sources: their own experiments, personal communication with other scientists, and textual material (print or electronic). For textual information, most study participants relied on personal journal subscriptions. Tangential journals were scanned in the department's library. Only a few of these scientists came to the health sciences library on a regular basis. Further, the study found that personal computers have had a major impact on how biotechnologists get and use information. Implications of these findings for libraries and librarians are discussed.

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.

Perceptions on nuclear energy: scientists, media and the public

International Nuclear Information System (INIS)

Parthasarathy, K.S.

2009-01-01

Full text: In 1990, when the International Atomic Energy Agency (IAEA) held its first Public Information Forum 'Nuclear Power: Communicating for Confidence', in Vienna, it reflected the international recognition that public opinion is one of the factors that influence acceptance of nuclear power in the energy mix of a country. Atomic bomb, nuclear proliferation, nuclear waste, exploding reactor (Chernobyl) and now nuclear terrorism stigmatized nuclear industry. In spite of the notable records, large segments of society are still concerned about this form of energy. 'Lack of understanding and misconceptions contribute to this', the first IAEA Forum conceded. Many felt that nuclear community supported this mystique 'by shrouding its operations in a secrecy that could not be penetrated'. Is DAE secretive in publicizing safety-related information? Right from 1947, Nehru's vision an Bhabha's mission on atomic energy coincided. They set up a sound administrative mechanism to respond swiftly, effectively and decisively to the demands from this nascent field. Scientists could not have asked for more. My generation participated in or was witness to the momentous developments in the field. We had a unique opportunity to examine how various sections of the population perceived nuclear technology. How did scientists take up the challenge? The National Symposium of Atomic Energy (November 26-27, 1954) was the first effort to dispel the mood of discontent. Nuclear scientists in India largely remained out of public gaze for long. They were at a disadvantage. They were not used to disorderly democratic debate, other than attending a few press conferences; media paid no attention to atomic energy. Even mild criticism could upset scientists; they were not used to it. Some scientists portrayed journalists who challenged official views as trouble makers. Mixing with the media was considered a risky occupation. During the first half of the fifty years of atomic energy, the public

Distributed tactical reasoning framework for intelligent vehicles

Sukthankar, Rahul; Pomerleau, Dean A.; Thorpe, Chuck E.

1998-01-01

In independent vehicle concepts for the Automated Highway System (AHS), the ability to make competent tactical-level decisions in real-time is crucial. Traditional approaches to tactical reasoning typically involve the implementation of large monolithic systems, such as decision trees or finite state machines. However, as the complexity of the environment grows, the unforeseen interactions between components can make modifications to such systems very challenging. For example, changing an overtaking behavior may require several, non-local changes to car-following, lane changing and gap acceptance rules. This paper presents a distributed solution to the problem. PolySAPIENT consists of a collection of autonomous modules, each specializing in a particular aspect of the driving task - classified by traffic entities rather than tactical behavior. Thus, the influence of the vehicle ahead on the available actions is managed by one reasoning object, while the implications of an approaching exit are managed by another. The independent recommendations form these reasoning objects are expressed in the form of votes and vetos over a 'tactical action space', and are resolved by a voting arbiter. This local independence enables PolySAPIENT reasoning objects to be developed independently, using a heterogenous implementation. PolySAPIENT vehicles are implemented in the SHIVA tactical highway simulator, whose vehicles are based on the Carnegie Mellon Navlab robots.

Execution of a self-directed risk assessment methodology to address HIPAA data security requirements

Coleman, Johnathan

2003-05-01

This paper analyzes the method and training of a self directed risk assessment methodology entitled OCTAVE (Operationally Critical Threat Asset and Vulnerability Evaluation) at over 170 DOD medical treatment facilities. It focuses specifically on how OCTAVE built interdisciplinary, inter-hierarchical consensus and enhanced local capabilities to perform Health Information Assurance. The Risk Assessment Methodology was developed by the Software Engineering Institute at Carnegie Mellon University as part of the Defense Health Information Assurance Program (DHIAP). The basis for its success is the combination of analysis of organizational practices and technological vulnerabilities. Together, these areas address the core implications behind the HIPAA Security Rule and can be used to develop Organizational Protection Strategies and Technological Mitigation Plans. A key component of OCTAVE is the inter-disciplinary composition of the analysis team (Patient Administration, IT staff and Clinician). It is this unique composition of analysis team members, along with organizational and technical analysis of business practices, assets and threats, which enables facilities to create sound and effective security policies. The Risk Assessment is conducted in-house, and therefore the process, results and knowledge remain within the organization, helping to build consensus in an environment of differing organizational and disciplinary perspectives on Health Information Assurance.

In Brief: Improving Mississippi River water quality

Showstack, Randy

2007-10-01

If water quality in the Mississippi River and the northern Gulf of Mexico is to improve, the U.S. Environmental Protection Agency (EPA) needs to take a stronger leadership role in implementing the federal Clean Water Act, according to a 16 October report from the U.S. National Research Council. The report notes that EPA has failed to use its authority to coordinate and oversee activities along the river. In addition, river states need to be more proactive and cooperative in efforts to monitor and improve water quality, and the river should be monitored and evaluated as a single system, the report indicates. Currently, the 10 states along the river conduct separate and widely varying water quality monitoring programs. ``The limited attention being given to monitoring and managing the Mississippi's water quality does not match the river's significant economic, ecological, and cultural importance,'' said committee chair David A. Dzombak, director of the Steinbrenner Institute for Environmental Education and Research at Carnegie Mellon University, Pittsburgh, Pa. The report notes that while measures taken under the Clean Water Act have successfully reduced much point source pollution, nutrient and sediment loads from nonpoint sources continue to be significant problems.

This paper describes a high-power density, silicon-based micro-scale direct methanol fuel cell (DMFC), under development at Carnegie Mellon. Major issues in the DMFC design include the water management and energy-efficient micro fluidic sub-systems. The air flow and the methanol circulation are both at a natural draft, while a passive liquid-gas separator removes CO 2 from the methanol chamber. An effective approach for maximizing the DMFC energy density, pumping the excess water back to the anode, is illustrated. The proposed DMFC contains several unique features: a silicon wafer with arrays of etched holes selectively coated with a non-wetting agent for collecting water at the cathode; a silicon membrane micro pump for pumping the collected water back to the anode; and a passive liquid-gas separator for CO 2 removal. All of these silicon-based components are fabricated using micro-electro-mechanical systems (MEMS)-based processes on the same silicon wafer, so that interconnections are eliminated, and integration efforts as well as post-fabrication costs are both minimized. The resulting fuel cell has an overall size of one cubic inch, produces a net output of 10 mW, and has an energy density three to five times higher than that of current lithium-ion batteries

The scientist's role in the nuclear debate

International Nuclear Information System (INIS)

Blackstein, F.P.

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

Sun-Earth Connection scientists have established partnerships with several minority professional societies to reach out to the blacks, Hispanics and Native American students. Working with NSBP, SACNAS, AISES and NSHP, SEC scientists were able to speak in their board meetings and national conferences, to network with minority scientists, and to engage them in Sun-Earth Day. Through these opportunities and programs, scientists have introduced NASA research results as well indigenous views of science. They also serve as role models in various communities. Since the theme for Sun-Earth Day 2005 is Ancient Observatories: Timeless Knowledge, scientists and education specialists are hopeful to excite many with diverse backgrounds. Sun-Earth Day is a highly visible annual program since 2001 that touches millions of students and the general public.

Lessons Learned from L'Aquila Trial for Scientists' Communication

Science.gov (United States)

Koketsu, K.; Cerase, A.; Amato, A.; Oki, S.

2017-12-01

The Appeal and Supreme Courts of Italy concluded that there was no bad communication by defendants except for the "glass of wine interview" which was made by a government official before the scientists' meeting. This meeting was held 6 days before the 2009 L'Aquila earthquake to discuss the outlook for the seismic activity in the L'Aquila area. However, at least two TV stations and a newspaper reported the content of the "glass of wine interview" in the next morning as it was announced by the defendant scientists. The reports triggered a domino effect of misinterpretations, which may be well acknowledged in the light of the social amplification of risk framework. These TV stations and newspaper should be also considered responsible for the bad communication. This point was missing in the sentence documents by the Appeal and Supreme Courts. Therefore, for scientists, a lesson of communication, especially during a seismic hazard crisis, is that they must carefully craft their messages and the way they circulate, both in broadcast and digital media, and follow reports released by the media on their activities. As another lesson, scientists must be aware that key concepts of safety such as "no danger" and "favorable situation", which were used in the "glass of wine interview", and the idea of probability can have different meanings for scientists, media, and citizens.

Finding Common Ground Between Earth Scientists and Evangelical Christians

Grant Ludwig, L.

2015-12-01

In recent decades there has been some tension between earth scientists and evangelical Christians in the U.S., and this tension has spilled over into the political arena and policymaking on important issues such as climate change. From my personal and professional experience engaging with both groups, I find there is much common ground for increasing understanding and communicating the societal relevance of earth science. Fruitful discussions can arise from shared values and principles, and common approaches to understanding the world. For example, scientists and Christians are engaged in the pursuit of truth, and they value moral/ethical decision-making based on established principles. Scientists emphasize the benefits of research "for the common good" while Christians emphasize the value of doing "good works". Both groups maintain a longterm perspective: Christians talk about "the eternal" and geologists discuss "deep time". Both groups understand the importance of placing new observations in context of prior understanding: scientists diligently reference "the literature" while Christians quote "chapter and verse". And members of each group engage with each other in "fellowship" or "meetings" to create a sense of community and reinforce shared values. From my perspective, earth scientists can learn to communicate the importance and relevance of science more effectively by engaging with Christians in areas of common ground, rather than by trying to win arguments or debates.

Women scientists' scientific and spiritual ways of knowing

Science.gov (United States)

Buffington, Angela Cunningham

While science education aims for literacy regarding scientific knowledge and the work of scientists, the separation of scientific knowing from other knowing may misrepresent the knowing of scientists. The majority of science educators K-university are women. Many of these women are spiritual and integrate their scientific and spiritual ways of knowing. Understanding spiritual women of science would inform science education and serve to advance the scientific reason and spirituality debate. Using interviews and grounded theory, this study explores scientific and spiritual ways of knowing in six women of science who hold strong spiritual commitments and portray science to non-scientists. From various lived experiences, each woman comes to know through a Passive knowing of exposure and attendance, an Engaged knowing of choice, commitment and action, an Mindful/Inner knowing of prayer and meaning, a Relational knowing with others, and an Integrated lifeworld knowing where scientific knowing, spiritual knowing, and other ways of knowing are integrated. Consequences of separating ways of knowing are discussed, as are connections to current research, implications to science education, and ideas for future research. Understanding women scientists' scientific/ spiritual ways of knowing may aid science educators in linking academic science to the life-worlds of students.

Scientists' internal models of the greenhouse effect

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.

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.

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

Directory of Open Access Journals (Sweden)

Adam K Fetterman

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

Where on the Web can a middle school girl ask a female solar scientist about solar storms, the course and behavior of charged solar particles, and the origin of the Sun's dynamo—and also find out what the scientist was like as a child, whether the scientist has tattoos or enjoys snowboarding, what she likes and dislikes about her career, and how she balances her energy for work and family life? These kinds of exchanges happen at Solar Week (http://www.solarweek.org; see Figure 1). Established in 2000, Solar Week is an online resource for middle and lower high school students about the science of the Sun, sponsored by the Center for Science Education at the Space Sciences Laboratory (CSE@SSL) at the University of California, Berkeley (UC Berkeley). The Web site's goals are to educate students about the Sun and solar physics and to encourage future careers in science—especially for girls. One way is by giving solar scientists the chance to be relatable role models, to answer students' questions, and to share their experiences in an online forum.

K-12 Students' Perceptions of Scientists: Finding a valid measurement and exploring whether exposure to scientists makes an impact

This study was launched from a National Science Foundation GK-12 grant in which graduate fellows in Science, Technology, Engineering, and Mathematics (STEM) are placed in classrooms to engage K-12 students in STEM activities. The investigation explored whether the STEM Fellows' presence impacted the K-12 students' stereotypical image of a scientist. Since finding a valid instrument is critical, the study involved (1) determining the validity of the commonly administered Draw-A-Scientist Test (DAST) against a newly designed six-question survey and (2) using a combination of both instruments to determine what stereotypes are currently held by children. A pretest-posttest design was used on 485 students, grades 3-11, attending 6 different schools in suburban and rural Maine communities. A significant but low positive correlation was found between the DAST and the survey; therefore, it is imperative that the DAST not be used alone, but corroboration with interviews or survey questions should occur. Pretest results revealed that the children held common stereotypes of scientists, but these stereotypes were neither as extensive nor did they increase with the grade level as past research has indicated, suggesting that a shift has occurred with children having a broader concept of who a scientist can be. Finally, the presence of an STEM Fellow corresponded with decreased stereotypes in middle school and high school, but no change in elementary age children. More research is needed to determine whether this reflects resiliency in elementary children's perceptions or limitations in either drawing or in writing out their responses.

Gap between science and media revisited: scientists as public communicators.

Peters, Hans Peter

2013-08-20

The present article presents an up-to-date account of the current media relations of scientists, based on a comprehensive analysis of relevant surveys. The evidence suggests that most scientists consider visibility in the media important and responding to journalists a professional duty--an attitude that is reinforced by universities and other science organizations. Scientific communities continue to regulate media contacts with their members by certain norms that compete with the motivating and regulating influences of public information departments. Most scientists assume a two-arena model with a gap between the arenas of internal scientific and public communication. They want to meet the public in the public arena, not in the arena of internal scientific communication. Despite obvious changes in science and in the media system, the orientations of scientists toward the media, as well as the patterns of interaction with journalists, have their roots in the early 1980s. Although there is more influence on public communication from the science organizations and more emphasis on strategic considerations today, the available data do not indicate abrupt changes in communication practices or in the relevant beliefs and attitudes of scientists in the past 30 y. Changes in the science-media interface may be expected from the ongoing structural transformation of the public communication system. However, as yet, there is little evidence of an erosion of the dominant orientation toward the public and public communication within the younger generation of scientists.

The Scientist and the Educational Development Team: An Impedance Mismatch?

Science.gov (United States)

Pompea, S. M.

2001-05-01

This talk describes my experiences and those of several other scientists who have worked on teams to develop new instructional materials and programs. At each stage of the development process we try to communicate our skills and experiences to the rest of the development team. In turn, the experiences of non-scientist educators on the team must be communicated to us. However, in many cases there is an "impedance mismatch" which makes communication difficult. One primary source of this mismatch is the scientist's lack of experience with schools, students, teachers, school administrators, museums, and the public. The result of this mismatch can leave the scientist in one limited, but useful role: proofreader and critic. Unfortunately, this can hardly be described as a partnership. This talk gives some advice, based on 25 years of educational materials and program development work, on how to avoid such a limited role. The talk would be appropriate for those scientists who want to lead, inspire, or significantly contribute to educational initiatives and to share in the frustration and the rewards enjoyed by professional educators and professional educational developers.

Scientists from a Russian nuclear research institute recently held a news conference in Moscow to publicize their work on a revolutionary new type of nuclear reactor. However, it transpired that the scientists were worried about their institute being closed down, and saw the news conference as an opportunity to draw attention to their plight (1 page).

Should We All be Scientists? Re-thinking Laboratory Research as a Calling.

In recent years there have been major shifts in how the role of science-and scientists-are understood. The critical examination of scientific expertise within the field of Science and Technology Studies (STS) are increasingly eroding notions of the "otherness" of scientists. It would seem to suggest that anyone can be a scientist-when provided with the appropriate training and access to data. In contrast, however, ethnographic evidence from the scientific community tells a different story. Scientists are quick to recognize that not everyone can-or should-be a scientist. Appealing to notions such as "good hands" or "gut feelings", scientists narrate a distinction between good and bad scientists that cannot be reduced to education, access, or opportunity. The key to good science requires scientists to express an intuitive feeling for their discipline, but also that individuals derive considerable personal satisfaction from their work. Discussing this personal joy in-and "fittingness" of-scientific occupations using the fields of STS, ethics and science policy is highly problematic. In this paper we turn to theology discourse to analyze the notion of "callings" as a means of understanding this issue. Callings highlight the identification and examination of individual talents to determine fit occupations for specific persons. Framing science as a calling represents a novel view of research that places the talents and dispositions of individuals and their relationship to the community at the center of flourishing practices.

Both scientists and the public would benefit from improved communication of basic scientific research and from integrating scientists into education outreach, but opportunities to support these efforts are limited. We have developed two low-cost programs—"Present Your PhD Thesis to a 12-Year-Old" and "Shadow a Scientist”—that combine training in science communication with outreach to area middle schools. We assessed the outcomes of these programs and found a 2-fold benefit: scientists improve their communication skills by explaining basic science research to a general audience, and students' enthusiasm for science and their scientific knowledge are increased. Here we present details about both programs, along with our assessment of them, and discuss the feasibility of exporting these programs to other universities. PMID:26844991

The Carnegie Supernova Project I. Methods to estimate host-galaxy reddening of stripped-envelope supernovae

We aim to improve upon contemporary methods to estimate host-galaxy reddening of stripped-envelope (SE) supernovae (SNe). To this end the Carnegie Supernova Project (CSP-I) SE SN photometry data release, consisting of nearly three dozen objects, is used to identify a minimally reddened sub-sample for each traditionally defined spectroscopic sub-type (i.e., SNe IIb, SNe Ib, SNe Ic). Inspection of the optical and near-infrared (NIR) colors and color evolution of the minimally reddened sub-samples reveals a high degree of homogeneity, particularly between 0 d to +20 d relative to B-band maximum. This motivated the construction of intrinsic color-curve templates, which when compared to the colors of reddened SE SNe, yields an entire suite of optical and NIR color excess measurements. Comparison of optical/optical vs. optical/NIR color excess measurements indicates the majority of the CSP-I SE SNe suffer relatively low amounts of reddening (i.e., E(B-V)host 0.20 mag) objects with the Fitzpatrick (1999, PASP, 111, 63) reddening law model provides robust estimates of the host visual-extinction AVhost and RVhost. In the case of the SE SNe with relatively low amounts of reddening, a preferred value of RVhost is adopted for each sub-type, resulting in estimates of AVhost through Fitzpatrick (1999) reddening law model fits to the observed color excess measurements. Our analysis suggests SE SNe reside in galaxies characterized by a range of dust properties. We also find evidence that SNe Ic are more likely to occur in regions characterized by larger RVhost values compared to SNe IIb/Ib and they also tend to suffer more extinction. The later finding is consistent with work in the literature suggesting SNe Ic tend to occur in regions of on-going star formation. Based on observations collected at Las Campanas Observatory.

Full Text Available This study aims to describe and analyze the presence of social scientists, anthropologists, sociologists and political scientists in the field of public health. A survey by the Lattes Curriculum and sites of Medical Colleges, Institutes of Health Research Collective, seeking professionals who work in healthcare and have done some stage of their training in the areas of social sciences. In confluence with Norbert Elias' concepts of social networks and configuration of interdependence it was used fuzzy logic, and the tool free statistical software R version 2.12.0 which enabled a graphic representation of social scientists interdependence in the field of social sciences-health-social sciences. A total of 238 professionals were ready in 6 distinct clusters according to the distance or closer of each professional in relation to public health and social sciences. The work was shown with great analytical and graphical representation possibilities for social sciences of health, in using this innovative quantitative methodology.

Dual use and the ethical responsibility of scientists.

Ehni, Hans-Jörg

2008-01-01

The main normative problem in the context of dual use is to determine the ethical responsibility of scientists especially in the case of unintended, harmful, and criminal dual use of new technological applications of scientific results. This article starts from an analysis of the concepts of responsibility and complicity, examining alternative options regarding the responsibility of scientists. Within the context of the basic conflict between the freedom of science and the duty to avoid causing harm, two positions are discussed: moral skepticism and the ethics of responsibility by Hans Jonas. According to these reflections, four duties are suggested and evaluated: stopping research, systematically carrying out research for dual-use applications, informing public authorities, and not publishing results. In the conclusion it is argued that these duties should be considered as imperfect duties in a Kantian sense and that the individual scientist should be discharged as much as possible from obligations which follow from them by the scientific community and institutions created for this purpose.
