    Computational Science is an integral component of Brookhaven's multi science mission, and is a reflection of the increased role of computation across all of science. Brookhaven currently has major efforts in data storage and analysis for the Relativistic Heavy Ion Collider (RHIC) and the ATLAS detector at CERN, and in quantum chromodynamics. The Laboratory is host for the QCDOC machines (quantum chromodynamics on a chip), 10 teraflop/s computers which boast 12,288 processors each. There are two here, one for the Riken/BNL Research Center and the other supported by DOE for the US Lattice Gauge Community and other scientific users. A 100 teraflop/s supercomputer will be installed at Brookhaven in the coming year, managed jointly by Brookhaven and Stony Brook, and funded by a grant from New York State. This machine will be used for computational science across Brookhaven's entire research program, and also by researchers at Stony Brook and across New York State. With Stony Brook, Brookhaven has formed the New York Center for Computational Science (NYCCS) as a focal point for interdisciplinary computational science, which is closely linked to Brookhaven's Computational Science Center (CSC). The CSC has established a strong program in computational science, with an emphasis on nanoscale electronic structure and molecular dynamics, accelerator design, computational fluid dynamics, medical imaging, parallel computing and numerical algorithms. We have been an active participant in DOES SciDAC program (Scientific Discovery through Advanced Computing). We are also planning a major expansion in computational biology in keeping with Laboratory initiatives. Additional laboratory initiatives with a dependence on a high level of computation include the development of hydrodynamics models for the interpretation of RHIC data, computational models for the atmospheric transport of aerosols, and models for combustion and for energy utilization. The CSC was formed to bring together

    Epstein, Gerald L

    2009-12-01

    Over his entire career, Gerald Epstein has toiled at the nexus of science, technology, and security. From 2003 to 2009, he was Senior Fellow for Science and Security at the Center for Strategic and International Studies Homeland Security Program, where he worked on reducing biological weapons threats, improving national preparedness, and easing potential tensions between the scientific research and national security communities. Epstein came to CSIS from the Institute for Defense Analyses. From 1996 to 2001, he served in the White House Office of Science and Technology Policy. And from 1983 to 1989, and again from 1991 until its demise in 1995, Epstein worked at the Congressional Office of Technology Assessment, where he directed a study on the proliferation of weapons of mass destruction, alongside research on other global security topics. A recognized expert in biological risk reduction, Epstein was actually trained as a physicist, having received SB degrees in physics and electrical engineering from MIT, and a PhD in physics from the University of California at Berkeley. How, then, did he come to study the evolving threat from bioterrorism? "What compelled me about bioterrorism was that it was a stellar example of a topic that would lead to a train wreck between the scientific community and the security community unless they figured out how to work together," he said. "The distance between a laboratory and a very large consequence event is a lot shorter in biology than in any other field. I got into bioterrorism to help make sure that the security community doesn't get so scared of the science that it shuts it down, and that the science community isn't so oblivious of security concerns that it pays no attention to them." Epstein spoke on November 6, 2009, with contributing writer Madeline Drexler, author of Emerging Epidemics: The Menace of New Infections (Penguin, 2009), an updated version of an earlier volume. Drexler holds a visiting appointment at the

    The Los Alamos Neutron Science Center (LANSCE) facilities for Nuclear Science consist of a high-energy "white" neutron source (Target 4) with 6 flight paths, three low-energy nuclear science flight paths at the Lujan Center, and a proton reaction area. The neutron beams produced at the Target 4 complement those produced at the Lujan Center because they are of much higher energy and have shorter pulse widths. The neutron sources are driven by the 800-MeV proton beam of the LANSCE linear accelerator. With these facilities, LANSCE is able to deliver neutrons with energies ranging from a milli-electron volt to several hundreds of MeV, as well as proton beams with a wide range of energy, time and intensity characteristics. The facilities, instruments and research programs are described briefly.

    2001-01-01

    Students in the Young Astronaut Program at the Coca-Cola Space Science Center in Columbus, GA, constructed gloveboxes using the new NASA Student Glovebox Education Guide. The young astronauts used cardboard copier paper boxes as the heart of the glovebox. The paper boxes transformed into gloveboxes when the students pasted poster-pictures of an actual NASA microgravity science glovebox inside and outside of the paper boxes. The young astronauts then added holes for gloves and removable transparent top covers, which completed the construction of the gloveboxes. This image is from a digital still camera; higher resolution is not available.

  14. Survey on current hydrotherapy use among North American burn centers.

    Science.gov (United States)

    Davison, Peter G; Loiselle, Frederick B; Nickerson, Duncan

    2010-01-01

    The authors have reviewed hydrotherapy practices in North American burn centers and described the epidemiology of hydrotherapy-associated nosocomial infections. A web-based survey was distributed to the directors of all burn care facilities listed by the American Burn Association. Questions addressed aspects of practice, including the method, additives, disposable liners, decontamination practices, nosocomial pathogens, and perceptions regarding the "ideal" method of hydrotherapy. The response rate was 44%, 59 of 142 centers, or 827 of 1900 beds. Hydrotherapy is regularly used by 83% of centers. Among these centers, 10% use exclusively immersion hydrotherapy (IH), 54% use exclusively shower cart hydrotherapy (SCH), and 35% use a combination of IH and SCH. Disposable liners are used at 80% of centers. Tap water alone is used by 51% of centers, 27% add detergent, 16% chlorhexidine, and 7% povidone-iodine. The majority of centers (57%) do not routinely culture their hydrotherapy equipment, 20% culture weekly, 7% monthly, and 17% less than once per month. Directors believe that Pseudomonas aeruginosa, methicillin-sensitive Staphylococcus aureus, and methicillin-resistant S. aureus are the most common nosocomial pathogens, followed by Acinetobacter species and Candida albicans. The relative frequency of occurrence of the first three pathogens did not vary with regard to the hydrotherapy method used. Given the opportunity to redesign, 45% of burn unit directors would implement SCH only, 42% a combination of SCH and IH, 2% exclusively IH, and 11% no hydrotherapy or bedside irrigation only. The prevalence of hydrotherapy use at North American burn centers has decreased since 1990 (83% vs 95%), yet continues to be used at the majority of centers. The use of IH has also declined (55% vs 81%). The trend away from the exclusive use of IH will likely continue, because more centers incorporate showering methods.

  15. Evaluation of American Indian Science and Engineering Society Intertribal Middle School Science and Math Bowl Project

    Energy Technology Data Exchange (ETDEWEB)

    AISES, None

    2013-09-25

    The American Indian Science and Engineering Society (AISES) has been funded under a U.S. Department of Energy (DOE) grant (Grant Award No. DE-SC0004058) to host an Intertribal Middle-School Science and Math Bowl (IMSSMB) comprised of teams made up of a majority of American Indian students from Bureau of Indian Education-funded schools and public schools. The intent of the AISES middle school science and math bowl is to increase participation of American Indian students at the DOE-sponsored National Science Bowl. Although national in its recruitment scope, the AISES Intertribal Science and Math Bowl is considered a “regional” science bowl, equivalent to the other 50 regional science bowls which are geographically limited to states. Most regional bowls do not have American Indian student teams competing, hence the AISES bowl is meant to encourage American Indian student teams to increase their science knowledge in order to participate at the national level. The AISES competition brings together teams from various American Indian communities across the nation. Each team is provided with funds for travel to and from the event, as well as for lodging and meals. In 2011 and 2012, there were 10 teams participating; in 2013, the number of teams participating doubled to 20. Each Science and Math Bowl team is comprised of four middle school — grades 6 through 8 — students, one alternate, and a teacher who serves as advisor and coach — although in at least two cases, the coach was not a teacher, but was the Indian Education Coordinator. Each team member must have at least a 3.0 GPA. Furthermore, the majority of students in each team must be comprised of American Indian, Alaska Native or Native Hawaiian students. Under the current DOE grant, AISES sponsored three annual middle school science bowl competitions over the years 2011, 2012 and 2013. The science and math bowls have been held in late March concurrently with the National American Indian Science and

    2010-12-01

    National Science Foundation Science and Technology Centers (STCs) play a leading role in developing and evaluating “Better Broader Impacts”; best practices for recruiting a broad spectrum of American students into STEM fields and for educating these future professionals, as well as their families, teachers and the general public. With staff devoted full time to Broader Impacts activities, over the ten year life of a Center, STCs are able to address both a broad range of audiences and a broad range of topics. Along with other NSF funded centers, such as Centers for Ocean Sciences Education Excellence, Engineering Research Centers and Materials Research Science and Engineering Centers, STCs develop both models and materials that individual researchers can adopt, as well as, in some cases, direct opportunities for individual researchers to offer their disciplinary research expertise to existing center Broader Impacts Programs. The National Center for Earth-surface Dynamics is an STC headquartered at the University of Minnesota. NCED’s disciplinary research spans the physical, biological and engineering issues associated with developing an integrative, quantitative and predictive understanding of rivers and river basins. Funded in 2002, we have had the opportunity to partner with individuals and institutions ranging from formal to informal education and from science museums to Tribal and women’s colleges. We have developed simple table top physical models, complete museum exhibitions, 3D paper maps and interactive computer based visualizations, all of which have helped us communicate with this wide variety of learners. Many of these materials themselves or plans to construct them are available online; in many cases they have also been formally evaluated. We have also listened to the formal and informal educators with whom we partner, from whom we have learned a great deal about how to design Broader Impacts activities and programs.

    Science.gov (United States)

    Moses, J. F.

    2006-12-01

    NASA has built a multi-year set of transaction and user satisfaction information about the evolving, broad collection of earth science products from a diverse set of users of the Earth Observing System Data and Information System (EOSDIS). The transaction and satisfaction trends provide corroborative information to support perception and intuition, and can often be the basis for understanding the results of cross-cutting initiatives and for management decisions about future strategies. The information is available through two fundamental complementary methods, product and user transaction data collected regularly from the major science data centers, and user satisfaction information collected through the American Customer Satisfaction Index survey. The combination provides the fundamental data needed to understand utilization trends in the research community. This paper will update trends based on 2006 metrics from the NASA earth science data centers and results from the 2006 EOSDIS ACSI survey. Principle concepts are explored that lead to sound guidance for data center managers and strategists over the next year.

    During 1991, the Molecular Science Research Center (MSRC) experienced solid growth and accomplishment and the Environmental, and Molecular Sciences Laboratory (EMSL) construction project moved forward. We began with strong programs in chemical structure and dynamics and theory, modeling, and simulation, and both these programs continued to thrive. We also made significant advances in the development of programs in materials and interfaces and macromolecular structure and dynamics, largely as a result of the key staff recruited to lead these efforts. If there was one pervasive activity for the past year, however, it was to strengthen the role of the EMSL in the overall environmental restoration and waste management (ER/WM) mission at Hanford. These extended activities involved not only MSRC and EMSL staff but all PNL scientific and technical staff engaged in ER/WM programs.

    In the fall of 1998, MacMillan Hall opened at Brown University to students. In MacMillan Hall was the new Computer Learning Center, since named the EarthLab which was outfitted with high-end workstations and peripherals primarily focused on the use of remotely sensed and other spatial data in the environmental sciences. The NASA grant we received as part of the "Centers of Excellence in Applications of Remote Sensing to Regional and Global Integrated Environmental Assessments" was the primary source of funds to outfit this learning and research center. Since opening, we have expanded the range of learning and research opportunities and integrated a cross-campus network of disciplines who have come together to learn and use spatial data of all kinds. The EarthLab also forms a core of undergraduate, graduate, and faculty research on environmental problems that draw upon the unique perspective of remotely sensed data. Over the last two years, the Earthlab has been a center for research on the environmental impact of water resource use in and regions, impact of the green revolution on forest cover in India, the design of forest preserves in Vietnam, and detailed assessments of the utility of thermal and hyperspectral data for water quality analysis. It has also been used extensively for local environmental activities, in particular studies on the impact of lead on the health of urban children in Rhode Island. Finally, the EarthLab has also served as a key educational and analysis center for activities related to the Brown University Affiliated Research Center that is devoted to transferring university research to the private sector.

    Astrophysics and Space Science are becoming increasingly characterised by what is now known as “big data”, the bottlenecks for progress partly shifting from data acquisition to “data mining”. Truth is that the amount and rate of data accumulation in many fields already surpasses the local capabilities for its processing and exploitation, and the efficient conversion of scientific data into knowledge is everywhere a challenge. The result is that, to a large extent, isolated data archives risk being progressively likened to “data graveyards”, where the information stored is not reused for scientific work. Responsible and efficient use of these large data-sets means democratising access and extracting the most science possible from it, which in turn signifies improving data accessibility and integration. Improving data processing capabilities is another important issue specific to researchers and computer scientists of each field. The project presented here wishes to exploit the enormous potential opened up by information technology at our age to advance a model for a science data center in astronomy which aims to expand data accessibility and integration to the largest possible extent and with the greatest efficiency for scientific and educational use. Greater access to data means more people producing and benefiting from information, whereas larger integration of related data from different origins means a greater research potential and increased scientific impact. The project of the BSDC is preoccupied, primarily, with providing tools and solutions for the Brazilian astronomical community. It nevertheless capitalizes on extensive international experience, and is developed in full cooperation with the ASI Science Data Center (ASDC), from the Italian Space Agency, granting it an essential ingredient of internationalisation. The BSDC is Virtual Observatory-complient and part of the “Open Universe”, a global initiative built under the auspices of the

    The Los Alamos Neutron Science Center, or LANSCE, uses the first truly high-current medium-energy proton linear accelerator, which operated originally at a beam power of 1 MW for medium-energy nuclear physics. Today LANSCE continues operation as one of the most versatile accelerator-based user facilities in the world. During eight months of annual operation, scientists from around the world work at LANSCE to execute an extraordinarily broad program of defense and civilian research. Several areas operate simultaneously. The Lujan Neutron Scattering Center (Lujan Center) is a moderated spallation source (meV to keV), the Weapons Neutron Research Facility (WNR) is a bare spallation neutron source (keV to 800 MeV), and a new ultra-cold neutron source will be operational in 2005. These sources give LANSCE the ability to produce and use neutrons with energies that range over 14 orders of magnitude. LANSCE also supplies beam to WNR and two other areas for applications requiring protons. In a proton radiography (pRad) area, a sequence of narrow proton pulses is transmitted through shocked materials and imaged to study dynamic properties. In 2005, LANSCE began operating a facility that uses 100-MeV protons to produce medical radioisotopes. To sustain a vigorous program beyond this decade, LANSCE has embarked on a project to refurbish key elements of the facility and to plan capabilities beyond those that presently exist

    Complex natural resource issues require understanding a web of interactions among ecosystem components that are (1) interdisciplinary, encompassing physical, chemical, and biological processes; (2) spatially complex, involving movements of animals, water, and airborne materials across a range of landscapes and jurisdictions; and (3) temporally complex, occurring over days, weeks, or years, sometimes involving response lags to alteration or exhibiting large natural variation. Scientists in the Ecosystem Dynamics Branch of the U.S. Geological Survey, Fort Collins Science Center, investigate a diversity of these complex natural resource questions at the landscape and systems levels. This Fact Sheet describes the work of the Ecosystems Dynamics Branch, which is focused on energy and land use, climate change and long-term integrated assessments, herbivore-ecosystem interactions, fire and post-fire restoration, and environmental flows and river restoration.

    AGILE is a scientific mission of the Italian Space Agency (ASI) with INFN, INAF e CIFS participation, devoted to gamma-ray astrophysics. The satellite is in orbit since April 23rd, 2007. Gamma-ray astrophysics above 100 MeV is an exciting field of astronomical sciences that has received a strong impulse in recent years. Despite the small size and budget, AGILE produced several important scientific results, among which the unexpected discovery of strong and rapid gamma-ray flares from the Crab Nebula. This discovery won to the AGILE PI and the AGILE Team the prestigious Bruno Rossi Prize for 2012, an international recognition in the field of high energy astrophysics. We present here the AGILE data center main activities, and we give an overview of the AGILE scientific highlights after 5 years of operations

  7. Interior's Climate Science Centers: Focus or Fail

    Udall, B.

    2012-12-01

    After a whirlwind two years of impressive and critical infrastructure building, the Department of Interior's Climate Science Centers are now in a position to either succeed or fail. The CSCs have a number of difficult structural problems including too many constituencies relative to the available resources, an uneasy relationship among many of the constituencies including the DOI agencies themselves, a need to do science in a new, difficult and non-traditional way, and a short timeframe to produce useful products. The CSCs have built a broad and impressive network of scientists and stakeholders. These entities include science providers of the universities and the USGS, and decision makers from the states, tribes, DOI land managers and other federal agencies and NGOs. Rather than try to support all of these constituencies the CSCs would be better served by refocusing on a core mission of supporting DOI climate related decision making. The CSCs were designed to service the climate science needs of DOI agencies, many of which lost their scientific capabilities in the 1990s due to a well-intentioned but ultimately harmful re-organization at DOI involving the now defunct National Biological Survey. Many of these agencies would like to have their own scientists, have an uneasy relationship with the nominal DOI science provider, the USGS, and don't communicate effectively among themselves. The CSCs must not succumb to pursuing science in either the traditional mode of the USGS or in the traditional mode of the universities, or worse, both of them. These scientific partners will need to be flexible, learn how to collaborate and should expect to see fewer resources. Useful CSC processes and outputs should start with the recommendations of the 2009 NRC Report Informing Decisions in a Changing Climate: (1) begin with users' needs; (2) give priority to process over products; (3) link information producers and users; (4) build connections across disciplines and organizations

    The Beautiful Earth program, awarded by NASA's Competitive Opportunities in Education and Public Outreach for Earth and Space Science (EPOESS), is a live multi-media performance at partner science centers linked with hands-on workshops featuring Earth scientists and Native American experts. It aims to inspire, engage and educate diverse students in Earth science through an experience of viewing the Earth from space as one interconnected whole, as seen through the eyes of astronauts. The informal education program is an outgrowth of Kenji Williams' BELLA GAIA Living Atlas Experience (www.bellagaia.com) performed across the globe since 2008 and following the successful Earth Day education events in 2009 and 2010 with NASA's DLN (Digital Learning Network) http://tinyurl.com/2ckg2rh. Beautiful Earth takes a new approach to teaching, by combining live music and data visualizations, Earth Science with indigenous perspectives of the Earth, and hands-on interactive workshops. The program will utilize the emotionally inspiring multi-media show as a springboard to inspire participants to learn more about Earth systems and science. Native Earth Ways (NEW) will be the first module in a series of three "Beautiful Earth" experiences, that will launch the national tour at a presentation in October 2011 at the MOST science museum in collaboration with the Onandaga Nation School in Syracuse, New York. The NEW Module will include Native American experts to explain how they study and conserve the Earth in their own unique ways along with hands-on activities to convey the science which was seen in the show. In this first pilot run of the module, 110 K-12 students with faculty and family members of the Onandaga Nations School will take part. The goal of the program is to introduce Native American students to Earth Sciences and STEM careers, and encourage them to study these sciences and become responsible stewards of the Earth. The second workshop presented to participants will be the

    The Kepler mission is designed to continuously monitor up to 170,000 stars at a 30 minute cadence for 3.5 years searching for Earth-size planets. The data are processed at the Science Operations Center (SOC) at NASA Ames Research Center. Because of the large volume of data and the memory and CPU-intensive nature of the analysis, significant computing hardware is required. We have developed generic pipeline framework software that is used to distribute and synchronize the processing across a cluster of CPUs and to manage the resulting products. The framework is written in Java and is therefore platform-independent, and scales from a single, standalone workstation (for development and research on small data sets) to a full cluster of homogeneous or heterogeneous hardware with minimal configuration changes. A plug-in architecture provides customized control of the unit of work without the need to modify the framework itself. Distributed transaction services provide for atomic storage of pipeline products for a unit of work across a relational database and the custom Kepler DB. Generic parameter management and data accountability services are provided to record the parameter values, software versions, and other meta-data used for each pipeline execution. A graphical console allows for the configuration, execution, and monitoring of pipelines. An alert and metrics subsystem is used to monitor the health and performance of the pipeline. The framework was developed for the Kepler project based on Kepler requirements, but the framework itself is generic and could be used for a variety of applications where these features are needed.

    McCarthy, Tom

    2014-02-01

    In the decade after World War II, psychologists, eager to bring the benefits of counseling to larger numbers, convinced hundreds of American colleges and universities to establish counseling centers. Inspired by the educational-vocational counseling center founded by psychologists at the University of Minnesota in 1932, Carl R. Rogers's "client-centered" methods of personal adjustment counseling, and the 400-plus college counseling centers created by the Veterans Administration to provide the educational-vocational counseling benefit promised to returning World War II servicemen under the 1944 GI Bill, these counseling psychologists created a new place to practice where important currents in psychology, higher education, and federal policy converged and where they attempted to integrate educational-vocational counseling with personal adjustment counseling based on techniques from psychotherapy. By the mid-1960s, half of America's colleges and universities had established counseling centers, and more than 90% offered students educational, vocational, and psychological counseling services, a great achievement of the first generation of counseling psychologists.

    Native Science Field Centers (NSFCs) were created to engage youth and adults in environmental science activities through the integration of traditional Native ways of knowing (understanding about the natural world based on centuries of observation including philosophy, worldview, cosmology, and belief systems of Indigenous peoples), Native languages, and Western science concepts. This paper focuses on the Blackfeet Native Science Field Center, the Lakota Native Science Field Center, and the Wind River Native Science Field Center. One of the long-term, overarching goals of these NSFCs was to stimulate the interest of Native American students in ways that encouraged them to pursue academic and career paths in science, technology, engineering, and mathematics (STEM) fields. A great deal can be learned from the experiences of the NSFCs in terms of effective educational strategies, as well as advantages and challenges in blending Native ways of knowing and Western scientific knowledge in an informal science education setting. Hopa Mountain—a Bozeman, Montana-based nonprofit—partnered with the Blackfeet Community College on the Blackfeet Reservation, Fremont County School District #21 on the Wind River Reservation, and Oglala Lakota College on the Pine Ridge Reservation to cooperatively establish the Native Science Field Centers. This paper presents a profile of each NSFC and highlights their program components and accomplishments.

    The South Central Climate Science Center was established by the U.S. Department of the Interior in 2012 to increase understanding of climate change and coordinate an effective response to climate-change effects on Native American tribes and natural and cultural resources that the Department manages. The eight regional Climate Science Centers of the U.S. Department of the Interior work closely with natural-resource management agencies, university researchers, and others such as tribes and private landowners on climate-change issues. The relatively large number of Native Americans in the south central United States and their special knowledge of changing ecosystems make working with tribes and tribal members on climate-change issues particularly important in this part of the Nation. This circular describes priorities of the South Central Climate Science Center and provides information about resources available from Climate Science Centers and partner agencies regarding climate change. The circular also describes how this Climate Science Center, tribes and tribal members, and others can collaborate to minimize potential harmful effects of climate change on human society and our surrounding ecosystems.

  18. Examining science achievement of African American females in suburban middle schools: A mixed methods study

    Topping, Kecia C.

    This dissertation examined factors that affected the science achievement of African American females in suburban middle schools. The research literature informed that African American females are facing the barriers of race, gender, socioeconomic status, and cultural learning style preferences. Nationally used measurements of science achievement such as the Standardized Achievement Test, Tenth edition (SAT-10), National Assessment for Educational Progress, and National Center for Educational Statistics showed that African American females are continuing to falter in the areas of science when compared to other ethnic groups. This study used a transformative sequential explanatory mixed methods design. In the first, quantitative, phase, the relationships among the dependent variables, science subscale SAT-10 NCE scores, yearly averages, and the independent variables, attitude toward science scores obtained from the Modified Fennema-Sherman Attitudes toward Science Scale, socioeconomics, and caregiver status were tested. The participants were 150 African American females in grades 6 through 8 in four suburban middle schools located in the Southeastern United States. The results showed a positive, significant linear relationship between the females' attitude and their science subscale SAT-10 NCE scores and a positive, significant linear relationship between the females' attitudes and their yearly averages in science. The results also confirmed that attitude was a significant predictor of science subscale SAT-10 NCE scores for these females and that attitude and socioeconomics were significant predictors of the females' yearly averages in science. In the second, qualitative, phase, nine females purposefully selected from those who had high and low attitude towards science scores on the scale in the quantitative phase were interviewed. The themes that emerged revealed seven additional factors that impacted the females' science achievement. They were usefulness of science

The American Indian Science and Engineering Society (AISES) is an organization working to increase educational opportunity for American Indian students in science, engineering, and technology related fields (AISES, 2005). AISES provides pre-college support in science by promoting student science fair participation. The purpose of this qualitative research is to describe how American Indian student participation in science fairs and the relationship formed with their teacher affects academic achievement and the likelihood of continued education beyond high school. Two former American Indian students mentored by the principal investigator participated in this study. Four ethnographic research methods were incorporated: participant observation, ethnographic interviewing, search for artifacts, and auto-ethnographic researcher introspection (Eisenhart, 1988). After the interview transcripts, photos documenting past science fair participation, and researcher field notes were analyzed, patterns and themes emerged from the interviews that were supported in literature. American Indian academic success and life long learning are impacted by: (a) the effects of racism and oppression result in creating incredible obstacles to successful learning, (b) positive identity formation and the importance of family and community are essential in student learning, (c) the use of best practice in science education, including the use of curricular cultural integration for American Indian learners, supports student success, (d) the motivational need for student-directed educational opportunities (science fair/inquiry based research) is evident, (e) supportive teacher-student relationships in high school positively influences successful transitions into higher education.

    The objective of the Plasma Science and Innovation Center (PSI-Center) is to develop and deploy computational models that simulate conditions in smaller, concept-exploration plasma experiments. The PSIC group at the University of Wisconsin-Madison, led by Prof. Carl Sovinec, uses and enhances the Non-Ideal Magnetohydrodynamics with Rotation, Open Discussion (NIMROD) code, to simulate macroscopic plasma dynamics in a number of magnetic confinement configurations. These numerical simulations provide information on how magnetic fields and plasma flows evolve over all three spatial dimensions, which supplements the limited access of diagnostics in plasma experiments. The information gained from simulation helps explain how plasma evolves. It is also used to engineer more effective plasma confinement systems, reducing the need for building many experiments to cover the physical parameter space. The ultimate benefit is a more cost-effective approach to the development of fusion energy for peaceful power production. The supplemental funds provided by the American Recovery and Reinvestment Act of 2009 were used to purchase computer components that were assembled into a 48-core system with 256 Gb of shared memory. The system was engineered and constructed by the group's system administrator at the time, Anthony Hammond. It was successfully used by then graduate student, Dr. John O'Bryan, for computing magnetic relaxation dynamics that occur during experimental tests of non-inductive startup in the Pegasus Toroidal Experiment (pegasus.ep.wisc.edu). Dr. O'Bryan's simulations provided the first detailed explanation of how the driven helical filament of electrical current evolves into a toroidal tokamak-like plasma configuration.

    The National Oceanic and Atmospheric Administration's National Geophysical Data Center (NGDC) World Data Center for Geophysics and Marine Geology provides scientific stewardship, products and services for geophysical data, including bathymetry, gravity, magnetics, seismic reflection, data derived from sediment and rock samples, as well as historical natural hazards data (tsunamis, earthquakes, and volcanoes). Although NGDC has long made many of its datasets available through map and other web services, it has now developed a second generation of services to improve the discovery and access to data. These new services use off-the-shelf commercial and open source software, and take advantage of modern JavaScript and web application frameworks. Services are accessible using both RESTful and SOAP queries as well as Open Geospatial Consortium (OGC) standard protocols such as WMS, WFS, WCS, and KML. These new map services (implemented using ESRI ArcGIS Server) are finer-grained than their predecessors, feature improved cartography, and offer dramatic speed improvements through the use of map caches. Using standards-based interfaces allows customers to incorporate the services without having to coordinate with the provider. Providing fine-grained services increases flexibility for customers building custom applications. The Integrated Ocean and Coastal Mapping program and Coastal and Marine Spatial Planning program are two examples of national initiatives that require common data inventories from multiple sources and benefit from these modern data services. NGDC is also consuming its own services, providing a set of new browser-based mapping applications which allow the user to quickly visualize and search for data. One example is a new interactive mapping application to search and display information about historical natural hazards. NGDC continues to increase the amount of its data holdings that are accessible and is augmenting the capabilities with modern web

  18. “Not Designed for Us”: How Science Museums and Science Centers Socially Exclude Low-Income, Minority Ethnic Groups

    Dawson, Emily

    2014-01-01

    This paper explores how people from low-income, minority ethnic groups perceive and experience exclusion from informal science education (ISE) institutions, such as museums and science centers. Drawing on qualitative data from four focus groups, 32 interviews, four accompanied visits to ISE institutions, and field notes, this paper presents an analysis of exclusion from science learning opportunities during visits alongside participants’ attitudes, expectations, and conclusions about participation in ISE. Participants came from four community groups in central London: a Sierra Leonean group (n = 21), a Latin American group (n = 18), a Somali group (n = 6), and an Asian group (n = 13). Using a theoretical framework based on the work of Bourdieu, the analysis suggests ISE practices were grounded in expectations about visitors’ scientific knowledge, language skills, and finances in ways that were problematic for participants and excluded them from science learning opportunities. It is argued that ISE practices reinforced participants preexisting sense that museums and science centers were “not for us.” The paper concludes with a discussion of the findings in relation to previous research on participation in ISE and the potential for developing more inclusive informal science learning opportunities.

  19. Contested Domains of Science and Science Learning in Contemporary Native American Communities: Three Case Studies from a National Science Foundation grant titled, "Archaeology Pathways for Native Learners"

    Parent, Nancy Brossard

    This dissertation provides a critical analysis of three informal science education partnerships that resulted from a 2003-2006 National Science Foundation grant titled, "Archaeology Pathways for Native Learners" (ESI-0307858), hosted by the Mashantucket Pequot Museum and Research Center. This dissertation is designed to contribute to understandings of learning processes that occur within and at the intersection of diverse worldviews and knowledge systems, by drawing upon experiences derived from three disparate contexts: 1) The Navajo Nation Museum in Window Rock, Arizona; 2) The A:shiwi A:wan Museum and Heritage Center on the Zuni Reservation in Zuni, New Mexico; and 3) Science learning camps at the Mashantucket Pequot Museum and Research Center for Native youth of southern New England. While informal science education is increasingly moving toward decolonizing and cross-cutting institutional boundaries of learning through critical thinking and real-world applications, the construction of "science" (even within diverse contexts) continues to be framed within a homogenous, predominantly Euro-American perspective. This study analyzes the language of Western science employed in these partnerships, with particular attention to the use of Western/Native binaries that shape perceptions of Native peoples and communities, real or imagined. Connections are drawn to broader nation-state interests in education, science, and the global economy. The role of educational evaluation in these case studies is also critically analyzed, by questioning the ways in which it is constructed, conducted, and evaluated for the purposes of informing future projects and subsequent funding. This study unpacks problems of the dominant language of "expert" knowledge embedded in Western science discourse, and highlights the possibilities of indigenous knowledge systems that can inform Western science frameworks of education and evaluation. Ultimately, this study suggests that research

  5. Visitor empowerment and the authority of science: Exploring institutionalized tensions in a science center

    Science.gov (United States)

    Loomis, Molly

    This research explored the relationships among societal, organizational, and visitor assumptions about learning in a science center. The study combined a sociocultural theory of learning with a constructivist theory of organizations to examine empirical links among the history of the Exploratorium (founded in 1969 and located in San Francisco, California), its organizational practices, and family activity at its exhibits. The study focused on three perspectives on science learning in a science center: (1) the societal perspective, which traced assumptions about science learning to the history of science centers; (2) the organizational perspective, which documented the ways that assumptions about science learning were manifested in historic museum exhibits; and (3) the family perspective, which documented the assumptions about science learning that characterized family activity at historic exhibits. All three perspectives uncovered a tension between the goals of supporting public empowerment on the one hand and preserving scientific authority on the other. Findings revealed this tension to be grounded in the social context of the organization's development, where ideas about promoting democracy and preserving the authority of science intersected. The tension was manifested in museum exhibits, which had as their task addressing the dual purposes of supporting all visitors, while also supporting committed visitors. The tension was also evident in the activity of families, who echoed sentiments about potential for their own empowerment but deferred to scientific authority. The study draws on critiques of a hidden curriculum in schools in order to explore the relationship between empowerment and authority in science centers, specifically as they are conveyed in the explicit and underlying missions of the Exploratorium. Findings suggest the need for science centers to engage in ongoing critical reflection and also lend empirical justification to the need for science

    In October, a new research center opened at the University of Manchester in the United Kingdom. The center is the product of over a decade of ground-breaking interdisciplinary research in the Earth and related biological and chemical sciences at the university The center also responds to the British governments policy of investing in research infrastructure at key universities.The Williamson Research Centre, the first of its kind in Britain and among the first worldwide, is devoted to the emerging field of molecular environmental science. This field also aims to bring about a revolution in understanding of our environment. Though it may be a less violent revolution than some, perhaps, its potential is high for developments that could affect us all.

  7. Should we establish a North American school of global health sciences?

    2004-08-01

    Since 1997, an unprecedented amount of American philanthropy from both private and federal sources has been directed toward research and control programs for the major tropical infectious diseases of developing countries. The US and Canadian capacity to respond to these new initiatives might prove inadequate, however, as tropical disease research and training infrastructures have deteriorated at most North American academic health centers over the last three decades. Training opportunities in clinical tropical medicine, parasitology laboratory diagnostics, vector control, and public health practice are especially depleted and portend a lost generation of experts in these areas. In addition, unlike some of the European schools of tropical medicine, no North American medical or public health school currently boasts a comprehensive faculty in the global health sciences, with expertise that spans laboratory investigation, clinical and translational research, health policy, and international development. To meet the challenge presented by the new philanthropy targeting the global diseases of poverty, a North American school of global health sciences should be established. The North American school, possibly in association with one of the existing schools of medicine or public health, would provide interdisciplinary training to produce a new generation of global health scientists.

    The Kepler Science Operations Center (SOC) is responsible for several aspects of the Kepler Mission, including managing targets, generating on-board data compression tables, monitoring photometer health and status, processing the science data, and exporting the pipeline products to the mission archive. We describe how the generic pipeline framework software developed for Kepler is extended to achieve these goals, including pipeline configurations for processing science data and other support roles, and custom unit of work generators that control how the Kepler data are partitioned and distributed across the computing cluster. We describe the interface between the Java software that manages the retrieval and storage of the data for a given unit of work and the MATLAB algorithms that process these data. The data for each unit of work are packaged into a single file that contains everything needed by the science algorithms, allowing these files to be used to debug and evolve the algorithms offline.

    We describe the Photometric Analysis (PA) software component and its context in the Kepler Science Operations Center (SOC) pipeline. The primary tasks of this module are to compute the photometric flux and photocenters (centroids) for over 160,000 long cadence (thirty minute) and 512 short cadence (one minute) stellar targets from the calibrated pixels in their respective apertures. We discuss the science algorithms for long and short cadence PA: cosmic ray cleaning; background estimation and removal; aperture photometry; and flux-weighted centroiding. We discuss the end-to-end propagation of uncertainties for the science algorithms. Finally, we present examples of photometric apertures, raw flux light curves, and centroid time series from Kepler flight data. PA light curves, centroid time series, and barycentric timestamp corrections are exported to the Multi-mission Archive at Space Telescope [Science Institute] (MAST) and are made available to the general public in accordance with the NASA/Kepler data release policy.

    In order to adequately perform its many diverse tasks as a scholars' society and as the German National Academy of Sciences, the Deutsche Akademie der Naturforscher Leopoldina needs to view itself in a historical context. This can only happen as part of a culture of remembrance which fosters the memory of the Leopoldina's past and subjects this to a critical analysis in the context of the history of science and academies. The newly founded Leopoldina Study Center for the History of Science and Science Academies is to be a forum that pursues established forms of historical research at the Leopoldina, organizes new scientific projects, and presents its findings to the public. The aim is to involve as many Leopoldina members as possible from all of its disciplines, as well as to collaborate with national and international partners.

    Seven regional Centers for Ocean Science Education Excellence have recently been established to promote the integration of ocean science research into high-quality education programs aimed at both formal and informal audiences throughout the United States. The regional Centers include two complementary partnerships in California, a New England regional effort, a Mid-Atlantic partnership, a Southeastern collaborative, a Florida initiative and a central Gulf of Mexico alliance. A Central Coordinating Office in Washington DC will help the group develop into a cohesive and focused national network. Initial funding has been provided by the National Science Foundation with complementary support from the Office of Naval Research and multiple units within the National Oceanographic and Atmospheric Administration (specifically the National Ocean Service, the Office of Ocean Exploration and the National SeaGrant Office). Under an umbrella of common goals and objectives, the first cohort of Centers in the COSEE network is remarkably diverse in terms of geography, organizational structure and programmatic focus. NSF’s presentation will describe these partnerships, the different approaches that are being taken by the individual Centers and the expectations that NSF has for the network as a whole.

    Broad-based geoscience instruction melding the Earth, space, and information technology sciences has been identified as an effective way to take advantage of the new jobs created by technological innovations in natural resources management. Based on this paradigm, the University of Hyderabad in India is developing a Centre of Earth and Space Sciences that will be linked to the university's super-computing facility. The proposed center will provide the basic science underpinnings for the Earth, space, and information technology sciences; develop new methodologies for the utilization of natural resources such as water, soils, sediments, minerals, and biota; mitigate the adverse consequences of natural hazards; and design innovative ways of incorporating scientific information into the legislative and administrative processes. For these reasons, the ethos and the innovatively designed management structure of the center would be of particular relevance to the developing countries. India holds 17% of the world's human population, and 30% of its farm animals, but only about 2% of the planet's water resources. Water will hence constitute the core concern of the center, because ecologically sustainable, socially equitable, and economically viable management of water resources of the country holds the key to the quality of life (drinking water, sanitation, and health), food security, and industrial development of the country. The center will be focused on interdisciplinary basic and pure applied research that is relevant to the practical needs of India as a developing country. These include, for example, climate prediction, since India is heavily dependent on the monsoon system, and satellite remote sensing of soil moisture, since agriculture is still a principal source of livelihood in India. The center will perform research and development in areas such as data assimilation and validation, and identification of new sensors to be mounted on the Indian meteorological

    NASA maintains an archive facility for Astronomical Science data collected from NASA's missions at the National Space Science Data Center (NSSDC) at Goddard Space Flight Center. This archive was created to insure the science data collected by NASA would be preserved and useable in the future by the science community. Through 25 years of operation there are many lessons learned, from data collection procedures, archive preservation methods, and distribution to the community. This document presents some of these more important lessons, for example: KISS (Keep It Simple, Stupid) in system development. Also addressed are some of the myths of archiving, such as 'scientists always know everything about everything', or 'it cannot possibly be that hard, after all simple data tech's do it'. There are indeed good reasons that a proper archive capability is needed by the astronomical community, the important question is how to use the existing expertise as well as the new innovative ideas to do the best job archiving this valuable science data.

    The Transiting Exoplanet Survey Satellite (TESS) science pipeline is being developed by the Science Processing Operations Center (SPOC) at NASA Ames Research Center based on the highly successful Kepler Mission science pipeline. Like the Kepler pipeline, the TESS science pipeline will provide calibrated pixels, simple and systematic error-corrected aperture photometry, and centroid locations for all 200,000+ target stars, observed over the 2-year mission, along with associated uncertainties. The pixel and light curve products are modeled on the Kepler archive products and will be archived to the Mikulski Archive for Space Telescopes (MAST). In addition to the nominal science data, the 30-minute Full Frame Images (FFIs) simultaneously collected by TESS will also be calibrated by the SPOC and archived at MAST. The TESS pipeline will search through all light curves for evidence of transits that occur when a planet crosses the disk of its host star. The Data Validation pipeline will generate a suite of diagnostic metrics for each transit-like signature discovered, and extract planetary parameters by fitting a limb-darkened transit model to each potential planetary signature. The results of the transit search will be modeled on the Kepler transit search products (tabulated numerical results, time series products, and pdf reports) all of which will be archived to MAST.

    The Office of Science, Basic Energy Sciences, has funded the INL as one of the Energy Frontier Research Centers in the area of material science of nuclear fuels. This document is the required annual report to the Office of Science that outlines the accomplishments for the period of May 2010 through April 2011. The aim of the Center for Material Science of Nuclear Fuels (CMSNF) is to establish the foundation for predictive understanding of the effects of irradiation-induced defects on thermal transport in oxide nuclear fuels. The science driver of the center's investigation is to understand how complex defect and microstructures affect phonon mediated thermal transport in UO2, and achieve this understanding for the particular case of irradiation-induced defects and microstructures. The center's research thus includes modeling and measurement of thermal transport in oxide fuels with different levels of impurities, lattice disorder and irradiation-induced microstructure, as well as theoretical and experimental investigation of the evolution of disorder, stoichiometry and microstructure in nuclear fuel under irradiation. With the premise that thermal transport in irradiated UO2 is a phonon-mediated energy transport process in a crystalline material with defects and microstructure, a step-by-step approach will be utilized to understand the effects of types of defects and microstructures on the collective phonon dynamics in irradiated UO2. Our efforts under the thermal transport thrust involved both measurement of diffusive phonon transport (an approach that integrates over the entire phonon spectrum) and spectroscopic measurements of phonon attenuation/lifetime and phonon dispersion. Our distinct experimental efforts dovetail with our modeling effort involving atomistic simulation of phonon transport and prediction of lattice thermal conductivity using the Boltzmann transport framework.

    2005-11-01

    Indigenous peoples of Turtle Island (North America) have had a special connection to and understanding of Mother Earth and Father Sky, and a long tradition of respect for the earth's resources. Based on this connection, understanding and respect, they have developed and used their own scientific theories and methods, and have used sustainable environmental practices. However, the problem is that despite centuries of scientific environmental practice and knowledge, Indigenous wisdom is virtually absent from the dominant mainstream Western science curriculums, literature, and practice. The purpose of this study is to explore Indigenous wisdom and how it might be better integrated into science and ecology education programs which are currently taught almost exclusively from Western perspectives. This study addresses the following two research questions: (1) What are the worldviews of Native American and science? (2) How can these worldviews be brought into mainstream Western science? The study of Indigenous wisdom involves an exploration of the stories a population of people whose core beliefs can not be easily quantified. A qualitative research approach, in-depth interviews and observations, have been selected for this study. The interviews and observations will be transcribed and the text will be reviewed and analyzed to find Indigenous worldviews and strategies for including these worldviews in current science curriculums.

    Climate change is not a thing of the future. Indigenous people are being affected by climate changes now. Native American Earth scientists could help Native communities deal with both climate change and environmental pollution issues, but are noticeably lacking in Earth Science degree programs. The Earth Sciences produce the lowest percentage of minority scientists when compared with other science and engineering fields. Twenty semi-structured interviews were gathered from American Indian/ Alaska Native Earth Scientists and program directors who work directly with Native students to broaden participation in the field. Data was analyzed using qualitative methods and constant comparison analysis. Barriers Native students faced in this field are discussed, as well as supports which go the furthest in assisting achievement of higher education goals. Program directors give insight into building pathways and programs to encourage Native student participation and success in Earth Science degree programs. Factors which impede obtaining a college degree include financial barriers, pressures from familial obligations, and health issues. Factors which impede the decision to study Earth Science include unfamiliarity with geoscience as a field of study and career choice, the uninviting nature of Earth Science as a profession, and curriculum that is irrelevant to the practical needs of Native communities or courses which are inaccessible geographically. Factors which impede progress that are embedded in Earth Science programs include educational preparation, academic information and counseling and the prevalence of a Western scientific perspective to the exclusion of all other perspectives. Intradepartmental relationships also pose barriers to the success of some students, particularly those who are non-traditional students (53%) or women (80%). Factors which support degree completion include financial assistance, mentors and mentoring, and research experiences. Earth scientists

    The Magnetospheric MultiScale (MMS) constellation of satellites completed their six month commissioning period in August, 2015 and began science operations. Science operations for the Solving Magnetospheric Acceleration, Reconnection, and Turbulence (SMART) instrument package occur at the Laboratory for Atmospheric and Space Physics (LASP). The Science Data Center (SDC) at LASP is responsible for the data production, management, distribution, and archiving of the data received. The mission will collect several gigabytes per day of particles and field data. Management of these data requires effective selection, transmission, analysis, and storage of data in the ground segment of the mission, including efficient distribution paths to enable the science community to answer the key questions regarding magnetic reconnection. Due to the constraints on download volume, this includes the Scientist-in-the-Loop program that identifies high-value science data needed to answer the outstanding questions of magnetic reconnection. Of particular interest to the community is the tools and associated website we have developed to provide convenient access to the data, first by the mission science team and, beginning March 1, 2016, by the entire community. This presentation will demonstrate the data and tools available to the community via the SDC and discuss the technologies we chose and lessons learned.

    Full Text Available Network Text Analysis (NTA is a term used to describe a variety of software - supported methods for modeling texts as networks of concepts. In this study we apply NTA to the screenplay of American Sniper, an Academy Award nominee for Best Adapted Screenplay in 2014. Specifically, we est ablish prior expectations as to the key themes associated with war films. We then empirically test whether words associated with the most influentially - positioned nodes in the network signify themes common to the war - film genre. As predicted, we find tha t words and concepts associated with the least constrained nodes in the text network were significantly more likely to be associated with the war genre and significantly less likely to be associated with genres to which the film did not belong.

    After five years experience in bringing American students to meet and learn with Russian students in Kamchatka and bringing Russian students to meet and learn with American students in Alaska, it is possible to make some generalizations about the problems and benefits this growing program. Some 200 students, including many from other countries besides the United States and Russian Federation, have now had this experience. The context of their collaboration is the International Volcanological Field School, sponsored by the University of Alaska Fairbanks, Kamchatka State University, and the Institute of Volcanology and Seismology, and also a comparison of Mount St Helens, Bezymianny, and Shiveluch volcanoes under the National Science Foundation's Partnerships in International Research in Education, with important support from the Russian Academy of Sciences, Far East Division. Elements of these two projects are adaptation to unfamiliar, harsh, and remote environments; intensive courses in Russian language, history, geography, and culture; and sharing of research and education experiences among students. The challenges faced by the program are: · Slow and complex visa processes. · Demise of a direct airline connection, necessitating round-the-world travel to go 3000 km. · Adequately communicating to students beforehand the need for physical fitness, mental fortitude in uncomfortable conditions, and patience when bad weather limits mobility. Benefits of the projects have been: · Experiences that students report to be career- and life-changing. · Much more positive perceptions of Russia and Russian people by American students and of America and Americans by Russian students. · Introduction to the "expedition style" volcanology necessary in challenging environments. · Development of long-lasting collaborations and friendships in the context of international science. Students often comment that hearing about what their peers have done or are doing in research at

    The Transiting Exoplanet Survey Satellite (TESS) was selected by NASA’s Explorer Program to conduct a search for Earth’s closest cousins starting in 2018. TESS will conduct an all-sky transit survey of F, G and K dwarf stars between 4 and 12 magnitudes and M dwarf stars within 200 light years. TESS is expected to discover 1,000 small planets less than twice the size of Earth, and to measure the masses of at least 50 of these small worlds. The TESS science pipeline is being developed by the Science Processing Operations Center (SPOC) at NASA Ames Research Center based on the highly successful Kepler science pipeline. Like the Kepler pipeline, the TESS pipeline provides calibrated pixels, simple and systematic error-corrected aperture photometry, and centroid locations for all 200,000+ target stars observed over the 2-year mission, along with associated uncertainties. The pixel and light curve products are modeled on the Kepler archive products and will be archived to the Mikulski Archive for Space Telescopes (MAST). In addition to the nominal science data, the 30-minute Full Frame Images (FFIs) simultaneously collected by TESS will also be calibrated by the SPOC and archived at MAST. The TESS pipeline searches through all light curves for evidence of transits that occur when a planet crosses the disk of its host star. The Data Validation pipeline generates a suite of diagnostic metrics for each transit-like signature, and then extracts planetary parameters by fitting a limb-darkened transit model to each potential planetary signature. The results of the transit search are modeled on the Kepler transit search products (tabulated numerical results, time series products, and pdf reports) all of which will be archived to MAST. Synthetic sample data products are available at https://archive.stsci.edu/tess/ete-6.html.Funding for the TESS Mission has been provided by the NASA Science Mission Directorate.

  8. Achievement Emotions as Predictors of High School Science Success Among African-American and European American Students

    Science.gov (United States)

    Bowe, Marilyn Louise Simmons

    The literature includes few studies of the interrelations of achievement goals and achievement emotions with respect to minority students and science achievement. The objective of this study was to test the control-value theory (CVT) of achievement emotions to determine if the eight discrete achievement emotions would be predictive of test scores on the High School Graduation Test (GHSGT)-Science for African-American compared to European-American science students. Convenience cluster sampling was employed to select 160 students who were all juniors in the same public high school at the time that they took the GHSGT-Science. The central research question for this study aimed to uncover whether any of the eight achievement emotions identified in CVT would contribute significantly to the predictability of science achievement as measured by GHSGT-Science scores. Data were collected using a nonexperimental, cross sectional design survey. Data were analyzed using a hierarchal, forced entry, multiple regression analysis. Key results indicated that the eight achievement emotions were predictive of GHSGT-Science score outcomes. Positive social change at the individual level could reflect a boost in confidence for African American science students and help decrease the achievement gap in science, technology, engineering, and mathematics (STEM) endeavors between European Americans and African-American students. Educators may consider the importance of achievement emotions in science outcomes by including social emotional learning (SEL) as a part of the regular science curriculum. Future researchers should repeat the study in a school district where the population is available to support the desired cluster sample of equal parts European Americans to African Americans and male to female students.

    Science education must be a priority for citizens to function and be productive in a global, technological society. African Americans receive fewer science degrees in proportion to the Caucasian population. The primary purposes of this study were to determine the difference between the pretest and posttest science self-efficacy scores of African-American nonscience majors, the difference between the pretest and posttest science self-efficacy scores of African-American science majors, the relationship between science self-efficacy and course grade, the relationship between gender and science self-efficacy score, and the relationship between science self-efficacy score and course withdrawal. This study utilized a Likert survey instrument. All participants were enrolled in freshman level courses in the physical sciences at a historically black institution: a college or university. Participants completed the pretest survey within two weeks after the 12th class day of the semester. Initially, 458 participants completed the pretest survey. The posttest was administered within two weeks before the final exam. Only 245 participants completed the posttest survey. Results indicate that there is a difference in science self-efficacy of science majors and nonscience majors. There was no significant difference between the pretest and posttest science self-efficacy scores of African-American science majors and nonscience majors. There was no significant relationship between science self-efficacy and course grade, gender and science self-efficacy score, and course withdrawal and science self-efficacy score.

    Young, Denise L.

    The purpose of this study was to examine the exhibition developer role in the context of United States (U.S.) science centers, and more specifically, to investigate the way science center exhibition developers build their professional expertise. This research investigated how successfully practicing exhibition developers described their current practices, how they learned to be exhibition developers, and what factors were the most important to the developers in building their professional expertise. Qualitative data was gathered from 10 currently practicing exhibition developers from three science centers: the Exploratorium, San Francisco, California; the Field Museum, Chicago, Illinois; and the Science Museum of Minnesota, St. Paul, Minnesota. In-depth, semistructured interviews were used to collect the data. The study embraced aspects of the phenomenological tradition and sought to derive a holistic understanding of the position and how expertise was built for it. The data were methodically coded and organized into themes prior to analysis. The data analysis found that the position consisted of numerous and varied activities, but the developers' primary roles were advocating for the visitor, storytelling, and mediating information and ideas. They conducted these activities in the context of a team and relied on an established exhibition planning process to guide their work. Developers described a process of learning exhibition development that was experiential in nature. Learning through daily practice was key, though they also consulted with mentors and relied on visitor studies to gauge the effectiveness of their work. They were adept at integrating prior knowledge gained from many aspects of their lives into their practice. The developers described several internal factors that contributed to their expertise development including the desire to help others, a natural curiosity about the world, a commitment to learning, and the ability to accept critique.

    The Life Science Division at NASA's Ames Research Center has a suite of specialized facilities that enable scientists to study the effects of gravity on living systems. This paper describes some of these facilities and their use in research. Seven centrifuges, each with its own unique abilities, allow testing of a variety of parameters on test subjects ranging from single cells through hardware to humans. The Vestibular Research Facility allows the study of both centrifugation and linear acceleration on animals and humans. The Biocomputation Center uses computers for 3D reconstruction of physiological systems, and interactive research tools for virtual reality modeling. Psycophysiological, cardiovascular, exercise physiology, and biomechanical studies are conducted in the 12 bed Human Research Facility and samples are analyzed in the certified Central Clinical Laboratory and other laboratories at Ames. Human bedrest, water immersion and lower body negative pressure equipment are also available to study physiological changes associated with weightlessness. These and other weightlessness models are used in specialized laboratories for the study of basic physiological mechanisms, metabolism and cell biology. Visual-motor performance, perception, and adaptation are studied using ground-based models as well as short term weightlessness experiments (parabolic flights). The unique combination of Life Science research facilities, laboratories, and equipment at Ames Research Center are described in detail in relation to their research contributions.

    2011-04-01

    The Office of Science, Basic Energy Sciences, has funded the INL as one of the Energy Frontier Research Centers in the area of material science of nuclear fuels. This document is the required annual report to the Office of Science that outlines the accomplishments for the period of May 2010 through April 2011. The aim of the Center for Material Science of Nuclear Fuels (CMSNF) is to establish the foundation for predictive understanding of the effects of irradiation-induced defects on thermal transport in oxide nuclear fuels. The science driver of the center’s investigation is to understand how complex defect and microstructures affect phonon mediated thermal transport in UO2, and achieve this understanding for the particular case of irradiation-induced defects and microstructures. The center’s research thus includes modeling and measurement of thermal transport in oxide fuels with different levels of impurities, lattice disorder and irradiation-induced microstructure, as well as theoretical and experimental investigation of the evolution of disorder, stoichiometry and microstructure in nuclear fuel under irradiation. With the premise that thermal transport in irradiated UO2 is a phonon-mediated energy transport process in a crystalline material with defects and microstructure, a step-by-step approach will be utilized to understand the effects of types of defects and microstructures on the collective phonon dynamics in irradiated UO2. Our efforts under the thermal transport thrust involved both measurement of diffusive phonon transport (an approach that integrates over the entire phonon spectrum) and spectroscopic measurements of phonon attenuation/lifetime and phonon dispersion. Our distinct experimental efforts dovetail with our modeling effort involving atomistic simulation of phonon transport and prediction of lattice thermal conductivity using the Boltzmann transport framework.

    Environmental science has entered into a big data era as enormous data about the Earth environment are continuously collected through field and airborne missions, remote sensing observations, model simulations, sensor networks, etc. An open-access and open-management data infrastructure for data-intensive science is a major grand challenge in global environmental research (BERAC, 2010). Such an infrastructure, as exemplified in EOSDIS, GEOSS, and NSF EarthCube, will provide a complete lifecycle of environmental data and ensures that data will smoothly flow among different phases of collection, preservation, integration, and analysis. Data archival centers, as the data integration units closest to data providers, serve as the source power to compile and integrate heterogeneous environmental data into this global infrastructure. This presentation discusses the interoperability challenges and practices of geosciences from the aspect of data archival centers, based on the operational experiences of the NASA-sponsored Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) and related environmental data management activities. Specifically, we will discuss the challenges to 1) encourage and help scientists to more actively share data with the broader scientific community, so that valuable environmental data, especially those dark data collected by individual scientists in small independent projects, can be shared and integrated into the infrastructure to tackle big science questions; 2) curate heterogeneous multi-disciplinary data, focusing on the key aspects of identification, format, metadata, data quality, and semantics to make them ready to be plugged into a global data infrastructure. We will highlight data curation practices at the ORNL DAAC for global campaigns such as BOREAS, LBA, SAFARI 2000; and 3) enhance the capabilities to more effectively and efficiently expose and deliver "big" environmental data to broad range of users and systems

    Davis, Edward

    This study investigated the relationship between an after-school tutorial program for African American high school students at a Title I school and scores on the science portion of the High School Graduation Examination (HSGE). Passing the examination was required for graduation. The target high school is 99% African American and the passing rate of the target high school was 42%---lower than the state average of 76%. The purpose of the study was to identify (a) the relationship between a science tutorial program and scores on the science portion of the HSGE, (b) the predictors of tutoring need by analyzing the relationship between biology grades and scores on the science portion of the HSGE, and (c) the findings between biology grades and scores on the science portion of the HSGE by analyzing the relationship between tutorial attendance and HSGE scores. The study was based on Piaget's cognitive constructivism, which implied the potential benefits of tutorials on high-stakes testing. This study used a 1-group pretest-posttest, quantitative methodology. Results showed a significant relationship between tutoring and scores on the biology portion of the HSGE. Results found no significant relationship between the tutorial attendance and the scores on the biology portion of the HSGE or between the biology grades and scores on the biology portion of the HSGE before tutoring. It has implications for positive social change by providing educational stakeholders with empirically-based guidance in determining the potential benefit of tutorial intervention strategies on high school graduation examination scores.

    IntroductionThe U.S. Geological Survey (USGS) Wetland and Aquatic Research Center (WARC) has two primary locations (Gainesville, Florida, and Lafayette, Louisiana) and field stations throughout the southeastern United States and Caribbean. WARC’s roots are in U.S. Fish and Wildlife Service (USFWS) and National Park Service research units that were brought into the USGS as the Biological Research Division in 1996. Founded in 2015, WARC was created from the merger of two long-standing USGS biology science Centers—the Southeast Ecological Science Center and the National Wetlands Research Center—to bring together expertise in biology, ecology, landscape science, geospatial applications, and decision support in order to address issues nationally and internationally. WARC scientists apply their expertise to a variety of wetland and aquatic research and monitoring issues that require coordinated, integrated efforts to better understand natural environments. By increasing basic understanding of the biology of important species and broader ecological and physiological processes, this research provides information to policymakers and aids managers in their stewardship of natural resources and in regulatory functions.This strategic science plan (SSP) was developed to guide WARC research during the next 5–10 years in support of Department of the Interior (DOI) partnering bureaus such as the USFWS, the National Park Service, and the Bureau of Ocean Energy Management, as well as other Federal, State, and local natural resource management agencies. The SSP demonstrates the alignment of the WARC goals with the USGS mission areas, associated programs, and other DOI initiatives. The SSP is necessary for workforce planning and, as such, will be used as a guide for future needs for personnel. The SSP also will be instrumental in developing internal funding priorities and in promoting WARC’s capabilities to both external cooperators and other groups within the USGS.

    Some conception of international science-education center on nano science in Vladivostok is presented. The conception is based on internal and external prerequisites. Internal one is high intellectual potential of institutes of Russian Academy of Sciences and universities of Vladivostok and external one is need of countries of Far Eastern region of Asia in high level manpower. The conception takes into account a specific distribution of science and education potential between Russian Academy of Sciences and Russian universities and a specific their dislocation in Vladivostok. First specific dictates some similarity of organization structure and function of international science-education center to typical science-education center in Russia. But as for dislocation of the international science-education center in Vladivostok, it should be near dislocation of institutes of Far Eastern Brunch of Russian Academy of Sciences in Vladivostok, which are dislocated very compactly in suburb zone of Vladivostok

    The articles in this volume relate, in one way or another, to a single experiment: the Michelson-Morley ether-drift experiment of 1887. About one-half of the articles in the collection are based on papers delivered at a two-day symposium ''The Michelson Era in American Science: 1870--1930,'' held a Case Western Reserve University in Cleveland, Ohio, 28--29 October 1987, commemorating the centennial of the experiment. The Michelson-Morley experiment was designed to detect the motion of the earth through the luminiferous ether. At the time, physicists did not question the existence of the ether. The experiment, like many physical probes of nature, was simple in conception, yet uncompromisingly demanding of the art of contemporary craftsmanship. The state of the mechanical arts and its relationship to the pursuit of physical science in late nineteenth- century America is well documented in Section I, which also addresses the more general question of the link between state-of-the-art shop practice and engineering theory

    2014-09-01

    Full Text Available Informal learning relates to activities that occur outside the school environment. These learning environments, such as visits to science centers provide valuable motivational opportunities for students to learn science. The purpose of this study was to investigate the role of the pre-academic center in science education and particularly to explore its effects on 750 middle-school students' attitudes toward science, their scientific thinking skills and self-efficacy. Pre and post-case based questionnaires were designed to assess the students’ higher order thinking skills – inquiry, graphing, and argumentation. In addition, a five-point Likert scale questionnaire was used to assess students' attitudes and self-efficacy. The research results indicated a positive effect of the pre-academic science center activities on scientific thinking skills. A significant improvement in the students' inquiry and graphing skills was found, yet non significant differences were found in argumentation skill. The students significantly improved their ability to ask research questions based on reading a scientific text, and to describe and analyze research results that were presented graphically. While no significant differences were found between girls and boys in the pre-questionnaire, in the post-questionnaire the girls' scores in inquiry skill were significantly higher than boys' scores. Increases in students' positive attitudes toward science and self-efficacy were found but the results were not statistically significant. However, the program length was found to be an important variable that affects achievement of educational goals. A three-dimension-based framework is suggested to characterize learning environments: organizational, psychological, and pedagogical.

    The Fort Collins Science Center's Policy Analysis and Science Assistance (PASA) Branch is a team of approximately 22 scientists, technicians, and graduate student researchers. PASA provides unique capabilities in the U.S. Geological Survey by leading projects that integrate social, behavioral, economic, and biological analyses in the context of human-natural resource interactions. Resource planners, managers, and policymakers in the U.S. Departments of the Interior (DOI) and Agriculture (USDA), State and local agencies, as well as international agencies use information from PASA studies to make informed natural resource management and policy decisions. PASA scientists' primary functions are to conduct both theoretical and applied social science research, provide technical assistance, and offer training to advance performance in policy relevant research areas. Management and research issues associated with human-resource interactions typically occur in a unique context, involve difficult to access populations, require knowledge of both natural/biological science in addition to social science, and require the skill to integrate multiple science disciplines. In response to these difficult contexts, PASA researchers apply traditional and state-of-the-art social science methods drawing from the fields of sociology, demography, economics, political science, communications, social-psychology, and applied industrial organization psychology. Social science methods work in concert with our rangeland/agricultural management, wildlife, ecology, and biology capabilities. The goal of PASA's research is to enhance natural resource management, agency functions, policies, and decision-making. Our research is organized into four broad areas of study.

    2018-05-01

    As part of an equipment grant provided by DOE-NP for the Center for Accelerator Target Science (CATS) initiative, the procurement of a new, electron beam, high-vacuum deposition system was identified as a priority to insure reliable and continued availability of high-purity targets. The apparatus is designed to contain TWO electron beam guns; a standard 4-pocket 270° geometry source as well as an electron bombardment source. The acquisition of this new system allows for the replacement of TWO outdated and aging vacuum evaporators. Also included is an additional thermal boat source, enhancing our capability within this deposition unit. Recommended specifications for this system included an automated, high-vacuum pumping station, a deposition chamber with a rotating and heated substrate holder for uniform coating capabilities and incorporating computer-controlled state-of-the-art thin film technologies. Design specifications, enhanced capabilities and the necessary mechanical modifications for our target work are discussed.

    The attitudes of faculty towards interprofessional education (IPE) and teamwork impact the education of health professions education (HPE) students. This paper reports on a study evaluating attitudes from health professions educators towards IPE and teamwork at one academic health science center (HSC) where modest IPE initiatives have commenced. Drawing from the results of a previous investigation, this study was conducted to examine current attitudes of the faculty responsible for the training of future healthcare professionals. Survey data were collected to evaluate attitudes from HSC faculty, dentistry, nursing, medicine, pharmacy and public health. In general, positive HSC faculty attitudes towards interprofessional learning, education, and teamwork were significantly predicted by those affiliated with the component of nursing. Faculty development aimed at changing attitudes and increasing understanding of IPE and teamwork are critical. Results of this study serve as an underpinning to leverage strengths and evaluate weakness in initiating IPE.

  12. Scheduling at the Los Alamos Neutron Science Center (LANSCE)

    1999-01-01

    The centerpieces of the Los Alamos Neutron Science Center (LANSCE) are a half-mile long 800-MeV proton linear accelerator and proton storage ring. The accelerator, storage ring, and target stations provide the protons and spallation neutrons that are used in the numerous basic research and applications experimental programs supported by the US Department of Energy. Experimental users, facility maintenance personnel, and operations personnel must work together to achieve the most program benefit within defined budget and resource constraints. In order to satisfy the experimental users programs, operations must provide reliable and high quality beam delivery. Effective and efficient scheduling is a critical component to achieve this goal. This paper will detail how operations scheduling is presently executed at the LANSCE accelerator facility

    2006-12-01

    In this study we investigate students' learning during their interaction with two exhibits at a science center. Specifically, we analyze both students' procedures when interacting with exhibits and their understanding of the scientific concepts presented therein. Bernstein's theory of pedagogic discourse (1990, 2000) provided the sociological foundation to assess the exhibit-student interaction and allowed analysis of the influence of the characteristics of students, exhibits, and interactions on students' learning. Eight students (ages 12ndash;13 years of age) with distinct sociological characteristics participated in the study. Several findings emerged from the results. First, the characteristics of the students, exhibits, and interactions appeared to influence student learning. Second, to most students, what they did interactively (procedures) seems not to have had any direct consequence on what they learned (concept understanding). Third, the data analysis suggest an important role for designers and teachers in overcoming the limitations of exhibit-student interaction.

  14. University/Science Center Collaborations (A Science Center Perspective): Developing an Infrastructure of Partnerships with Science Centers to Support the Engagement of Scientists and Engineers in Education and Outreach for Broad Impact

    Science.gov (United States)

    Marshall, Eric

    2009-03-01

    Science centers, professional associations, corporations and university research centers share the same mission of education and outreach, yet come from ``different worlds.'' This gap may be bridged by working together to leverage unique strengths in partnership. Front-end evaluation results for the development of new resources to support these (mostly volunteer-based) partnerships elucidate the factors which lead to a successful relationship. Maintaining a science museum-scientific community partnership requires that all partners devote adequate resources (time, money, etc.). In general, scientists/engineers and science museum professionals often approach relationships with different assumptions and expectations. The culture of science centers is distinctly different from the culture of science. Scientists/engineers prefer to select how they will ultimately share their expertise from an array of choices. Successful partnerships stem from clearly defined roles and responsibilities. Scientists/engineers are somewhat resistant to the idea of traditional, formal training. Instead of developing new expertise, many prefer to offer their existing strengths and expertise. Maintaining a healthy relationship requires the routine recognition of the contributions of scientists/engineers. As professional societies, university research centers and corporations increasingly engage in education and outreach, a need for a supportive infrastructure becomes evident. Work of TryScience.org/VolTS (Volunteers TryScience), the MRS NISE Net (Nanoscale Informal Science Education Network) subcommittee, NRCEN (NSF Research Center Education Network), the IBM On Demand Community, and IEEE Educational Activities exemplify some of the pieces of this evolving infrastructure.

  16. The perspectives and experiences of African American students in an informal science program

    Science.gov (United States)

    Bulls, Domonique L.

    Science, technology, engineering, and mathematics (STEM) fields are the fastest growing sectors of the economy, nationally and globally. In order for the United States (U.S.) to maintain its competitiveness, it is important to address STEM experiences at the precollege level. In early years, science education serves as a foundation and pipeline for students to pursue STEM in college and beyond. Alternative approaches to instruction in formal classrooms have been introduced to engage more students in science. One alternative is informal science education. Informal science education is an avenue used to promote science education literacy. Because it is less regulated than science teaching in formal classroom settings, it allows for the incorporation of culture into science instruction. Culturally relevant science teaching is one way to relate science to African American students, a population that continually underperforms in K-12 science education. This study explores the science perspectives and experiences of African American middle school students participating in an informal science program. The research is framed by the tenets of culturally relevant pedagogy and shaped by the following questions: (1) What specific aspects of the Carver Program make it unique to African American students? (2) How is culturally relevant pedagogy incorporated into the informal science program? (3) How does the incorporation of culturally relevant pedagogy into the informal science program influence African American students' perceptions about science? The findings to the previously stated questions add to the limited research on African American students in informal science learning environments and contribute to the growing research on culturally relevant science. This study is unique in that it explores the cultural components of an informal science program.

    West, R T; Howard, F H

    1977-07-01

    A study to determine the impact that the Area Health Education Center type of programs may have on health science libraries was conducted by the Extramural Programs, National Library of Medicine, in conjunction with a contract awarded by the Bureau of Health Manpower, Health Resources Administration, to develop an inventory of the AHEC type of projects in the United States. Specific study tasks included a review of these programs as they relate to library and information activities, on-site surveys on the programs to define their needs for library services and information, and a categorization of library activities. A major finding was that health science libraries and information services are generally not included in AHEC program planning and development, although information and information exchange is a fundamental part of the AHEC type of programs. This study suggests that library inadequacies are basically the result of this planning failure and of a lack of financial resources; however, many other factors may be contributory. The design and value of library activities for these programs needs explication.

    The new Stocker AstroScience Center located on the MMC campus at Florida International University in Miami Florida represents a unique facility for STEM education that arose from a combination of private, State and university funding. The building, completed in the fall of 2013, contains some unique spaces designed not only to educate, but also to inspire students interested in science and space exploration. The observatory consists of a 4-story building (3 floors) with a 24” ACE automated telescope in an Ash dome, and an observing platform above surrounding buildings. Some of the unique features of the observatory include an entrance/exhibition hall with a 6-ft glass tile floor mural linking the Florida climate to space travel, a state-of-the art telescope control that looks like a starship bridge, and displays such as “Music from the universe”. The observatory will also be the focus of our extensive public outreach program that is entering its 20 year.

    Grace, Shamarion Gladys

    This is a three-article five chapter doctoral dissertation. The overall purpose of this three-pronged study is to engage a middle school science teacher and students in formal-informal science education within the context of a science standards-based curriculum and Urban Science Center. The goals of the study were: (1) to characterize the conversations of formal and informal science educators as they attempted to implement a standards-based curriculum augmented with science center exhibits; (2) to study the classroom discourse between the teacher and students that foster the development of common knowledge in science and student understanding of the concept of energy before observing science center exhibits on energy; (3) to investigate whether or not a standards-driven, project-based Investigating and Questioning our World through Science and Technology (IQWST) curriculum unit on forms and transformation of energy augmented with science center exhibits had a significant effect on urban African-American seventh grade students' achievement and learning. Overall, the study consisted of a mixed-method approach. Article one consists of a case study featuring semi-structured interviews and field notes. Article two consists of documenting and interpreting teacher-students' classroom discourse. Article three consists of qualitative methods (classroom discussion, focus group interviews, student video creation) and quantitative methods (multiple choice and open-ended questions). Oral discourses in all three studies were audio-recorded and transcribed verbatim. In article one, the community of educators' conversations were critically analyzed to discern the challenges educators encountered when they attempted to connect school curriculum to energy exhibits at the Urban Science Center. The five challenges that characterize the emergence of a third space were as follows: (a) science terminology for lesson focus, (b) "dumb-down" of science exhibits, (c) exploration distracts

    The High Energy Astrophysics Science Archive Research Center (HEASARC) is NASA's archive for high-energy astrophysics and cosmic microwave background (CMB) data, supporting the broad science goals of NASA's Physics of the Cosmos theme. It provides vital scientific infrastructure to the community by standardizing science data formats and analysis programs, providing open access to NASA resources, and implementing powerful archive interfaces. Over the next five years the HEASARC will ingest observations from up to 12 operating missions, while serving data from these and over 30 archival missions to the community. The HEASARC archive presently contains over 37 TB of data, and will contain over 60 TB by the end of 2014. The HEASARC continues to secure major cost savings for NASA missions, providing a reusable mission-independent framework for reducing, analyzing, and archiving data. This approach was recognized in the NRC Portals to the Universe report (2007) as one of the HEASARC's great strengths. This poster describes the past and current activities of the HEASARC and our anticipated developments in coming years. These include preparations to support upcoming high energy missions (NuSTAR, Astro-H, GEMS) and ground-based and sub-orbital CMB experiments, as well as continued support of missions currently operating (Chandra, Fermi, RXTE, Suzaku, Swift, XMM-Newton and INTEGRAL). In 2012 the HEASARC (which now includes LAMBDA) will support the final nine-year WMAP data release. The HEASARC is also upgrading its archive querying and retrieval software with the new Xamin system in early release - and building on opportunities afforded by the growth of the Virtual Observatory and recent developments in virtual environments and cloud computing.

    At the end of World War II Duane Deming, an internationally known economist enunciated what later came to be called "Total Quality Management" (TQM). The basic thrust of this economic theory called for companies and governments to identify their customers and to do whatever was necessary to meet their demands and to keep them satisfied. It also called for companies to compete internally. That is, they were to build products that competed with their own so that they were always improving. Unfortunately most U.S. corporations failed to heed this advice. Consequently, the Japanese who actively sought Deming's advice and instituted it in their corporate planning, built an economy that outstripped that of the U.S. for the next three to four decades. Only after U.S. corporations reorganized and fashioned joint ventures which incorporated the tenets of TQM with their Japanese competitors did they start to catch up. Other institutions such as the U.S. government and its agencies and schools face the same problem. While the power of the U.S. government is in no danger of being usurped, its agencies and schools face real problems which can be traced back to not heeding Deming's advice. For example, the public schools are facing real pressure from private schools and home school families because they are not meeting the needs of the general public, Likewise, NASA and other government agencies find themselves shortchanged in funding because they have failed to convince the general public that their missions are important. In an attempt to convince the general public that its science mission is both interesting and important, in 1998 the Science Directorate at NASA's Marshall Space Flight Center (MSFC) instituted a new outreach effort using the interact to reach the general public as well as the students. They have called it 'Science@NASA'.

    Reports an error in "Great aspirations: The postwar American college counseling center" by Tom McCarthy ( History of Psychology , 2014[Feb], Vol 17[1], 1-18). In the article, the copyright attribution was incorrect. The copyright is "In the public domain". The online version of this article has been corrected. (The following abstract of the original article appeared in record 2014-04967-001.) In the decade after World War II, psychologists, eager to bring the benefits of counseling to larger numbers, convinced hundreds of American colleges and universities to establish counseling centers. Inspired by the educational-vocational counseling center founded by psychologists at the University of Minnesota in 1932, Carl R. Rogers's "client-centered" methods of personal adjustment counseling, and the 400-plus college counseling centers created by the Veterans Administration to provide the educational-vocational counseling benefit promised to returning World War II servicemen under the 1944 GI Bill, these counseling psychologists created a new place to practice where important currents in psychology, higher education, and federal policy converged and where they attempted to integrate educational-vocational counseling with personal adjustment counseling based on techniques from psychotherapy. By the mid-1960s, half of America's colleges and universities had established counseling centers, and more than 90% offered students educational, vocational, and psychological counseling services, a great achievement of the first generation of counseling psychologists.

    Han, Alyson Kim

    According to the California Commission on Teacher Credentialing (2001), one in three students speaks a language other than English. Additionally, the Commission stated that a student is considered to be an English learner if the second language acquisition is English. In California more than 1.4 million English learners enter school speaking a variety of languages, and this number continues to rise. There is an imminent need to promote instructional strategies that support this group of diverse learners. Although this was not a California study, the results derived from the nationwide participants' responses provided a congruent assessment of the basic need to provide effective science teaching strategies to all English learners. The purpose of this study was to examine the status of elementary science teaching practices used with English learners in kindergarten through fifth grade in public mathematics, science, and technology-centered elementary magnet schools throughout the country. This descriptive research was designed to provide current information and to identify trends in the areas of curriculum and instruction for English learners in science themed magnet schools. This report described the status of elementary (grades K-5) school science instruction for English learners based on the responses of 116 elementary school teachers: 59 grade K-2, and 57 grade 3-5 teachers. Current research-based approaches support incorporating self-directed learning strategy, expository teaching strategy, active listening strategies, questioning strategies, wait time strategy, small group strategy, peer tutoring strategy, large group learning strategy, demonstrations strategy, formal debates strategy, review sessions strategy, mediated conversation strategy, cooperative learning strategy, and theme-based instruction into the curriculum to assist English learners in science education.

    The Los Alamos Neutron Science Center (LANSCE) provides the scientific community with intense sources of neutrons, which can be used to perform experiments supporting civilian and national security research. These measurements include nuclear physics experiments for the defense program, basic science, and the radiation effect programs. This paper focuses on the radiation effects program, which involves mostly accelerated testing of semiconductor parts. When cosmic rays strike the earth's atmosphere, they cause nuclear reactions with elements in the air and produce a wide range of energetic particles. Because neutrons are uncharged, they can reach aircraft altitudes and sea level. These neutrons are thought to be the most important threat to semiconductor devices and integrated circuits. The best way to determine the failure rate due to these neutrons is to measure the failure rate in a neutron source that has the same spectrum as those produced by cosmic rays. Los Alamos has a high-energy and a low-energy neutron source for semiconductor testing. Both are driven by the 800-MeV proton beam from the LANSCE accelerator. The high-energy neutron source at the Weapons Neutron Research (WNR) facility uses a bare target that is designed to produce fast neutrons with energies from 100 keV to almost 800 MeV. The measured neutron energy distribution from WNR is very similar to that of the cosmic-ray-induced neutrons in the atmosphere. However, the flux provided at the WNR facility is typically 5×107 times more intense than the flux of the cosmic-ray-induced neutrons. This intense neutron flux allows testing at greatly accelerated rates. An irradiation test of less than an hour is equivalent to many years of neutron exposure due to cosmic-ray neutrons. The low-energy neutron source is located at the Lujan Neutron Scattering Center. It is based on a moderated source that provides useful neutrons from subthermal energies to ~100 keV. The characteristics of these sources

    2013-06-01

    We are witnessing an unprecedented development of the medical science, which promises to revolutionize health care and improve patients' health outcomes. However, the core of the medical profession has always been and will be the relationship between the doctor and the patient, and communication is the most widely used clinical skill in medical practice. When we talk about different forms of communication in medicine, we must never forget the importance of communication through art. Although one of the simplest, art is the most effective way to approach the patient and produce the effect that no other means of communication can achieve. Person-centered pain management takes into account psychological, physical, social, and spiritual aspects of health and disease. Art should be used as a therapeutic technique for people who suffer from pain, as well as a means of raising public awareness of this problem. Art can also be one of the best forms of educating medical professionals and others involved in treatment and decision-making on pain.

    2012-12-01

    The corpus of Earth Science data products at the Atmospheric Science Data Center at NASA's Langley Research Center comprises a widely heterogeneous set of products, even among those whose subject matter is very similar. Two distinct data products may both contain data on the same parameter, for instance, solar irradiance; but the instruments used, and the circumstances under which the data were collected and processed, may differ significantly. Understanding the differences is critical to using the data effectively. Data distribution services must be able to provide prospective users with enough information to allow them to meaningfully compare and evaluate the data products offered. Semantic technologies - ontologies, triple stores, reasoners, linked data - offer functionality for addressing this issue. Ontologies can provide robust, high-fidelity domain models that serve as common schema for discovering, evaluating, comparing and integrating data from disparate products. Reasoning engines and triple stores can leverage ontologies to support intelligent search applications that allow users to discover, query, retrieve, and easily reformat data from a broad spectrum of sources. We argue that because of the extremely complex nature of scientific data, data distribution systems should wholeheartedly embrace semantic technologies in order to make their data accessible to a broad array of prospective end users, and to ensure that the data they provide will be clearly understood and used appropriately by consumers. Toward this end, we propose a distribution system in which formal ontological models that accurately and comprehensively represent the ASDC's data domain, and fully leverage the expressivity and inferential capabilities of first order logic, are used to generate graph-based representations of the relevant relationships among data sets, observational systems, metadata files, and geospatial, temporal and scientific parameters to help prospective data consumers

    2017-12-01

    Because climate hazards present a range of potential impacts and considerations for different kinds of stakeholders, community responses to increase resilience are best considered through the inclusion of diverse, informed perspectives. The Science Center Public Forums project has created multifaceted modules to engage diverse publics in substantive deliberations around four hazards: heat waves, drought, extreme precipitation, and sea level rise. Using a suite of background materials including visualization and narrative components, each of these daylong dialogues engage varied groups of lay-participants at eight US science centers in learning about hazard vulnerabilities and tradeoffs of proposed strategies for building resilience. Participants listen to and consider the priorities and perspectives of fellow residents and stakeholders, and work together to formulate detailed resilience plans reflecting both current science and informed public values. Deliverables for the project include visualizations of hazard vulnerabilities and strategies through immersive planetarium graphics and Google Earth, stakeholder perspective narratives, and detailed background materials for each project hazard. This session will: communicate the process for developing the hazard modules with input from subject matter experts, outline the process for iterative revisions based upon findings from formative focus groups, share results generated by participants of the project's first two pilot forums, and describe plans for broader implementation. These activities and outcomes could help to increase the capacity of informal science education institutions as trusted conveners for informed community dialogue by educating residents about vulnerabilities and engaging them in critical thinking about potential policy responses to critical climate hazards while sharing usable public values and priorities with civic planners.

  3. Revisiting the "American Social Science" – Mapping the Geography of International Relations

    DEFF Research Database (Denmark)

    Kristensen, Peter Marcus

    2015-01-01

    International Relations (IR) knows itself as an American social science. The paper first traces how the self-image as a uniquely dividing and American social science was established in the postwar period and is reproduced to this day. Second, it employs bibliometric methods to challenge this image....... It confirms the dominance of Americans in a comprehensive sample of IR journals, but in contrast to previous studies, the paper also compares IR to other disciplines only to find that it is actually one of the least American social sciences. It further studies the geography of IR over time and finds that IR...... has become less American since the 1960s—mainly because Anglo-Saxon and European countries account for a larger share of IR production. The final part uses novel visualization tools to map the geographical network structures of authorship and coauthorship in the discipline’s leading journals...

  9. A study of the historical role of African Americans in science, engineering and technology

    Science.gov (United States)

    Jones, Keith Wayne

    2000-11-01

    The purpose of this study was to determine if there is adequate documentation of an historical role of African and African American involvement in science, engineering, and technology. Through the use of history of science and technology research methodology, along with an examination of the sociological and economic impacts of adequately accredited innovations and inventions contributed by Africans and African Americans, the researcher investigated their contributions to the following areas of science and technology: life science, physical sciences and chemistry, engineering, and science education. In regard to the timeframe for this study, the researcher specifically investigated African and African American involvement in science and technology that includes periods prior to black enslavement, scientific racism and colonialism, as well as during and after those periods. This research study reveals that there are adequate historical data regarding African and African American contributions to science, engineering, and technology. The data reveals that for many millennia African peoples have been continually involved in science and world science histories. The data further show that the numbers of African Americans acquiring BS, MS, Ph.D., Doctor of Science and Doctor of Engineering degrees in science and engineering disciplines are increasing. That these increases are not happening at a rate representative of the present or future African American percentages of the population. Consequently, because of future changes in our nation's demographics, increasing the numbers of people from under-represented groups who pursue scientific and engineering professions has become a matter of national security at the highest levels of government. Moreover, African Americans, Hispanics, and Native Americans are not pursuing careers or taking courses in science and engineering at a rate high enough to fulfill the prospective needs for the United States' industries, government

  10. Perceptions of selected science careers by African American high school males

    Science.gov (United States)

    Ijames, Erika Denise

    Research indicates that internal and external factors such as role models, stereotypes, and pressures placed on African American males by their family and friends influence their perceptions of science careers (Assibey-Mensah, 1997; Hess & Leal, 1997; Jacobowitz, 1983; Maple & Stage, 1991; Thomas, 1989; Ware & Lee, 1988). The purpose of this research was to investigate the perceptions of African American high school males about selected science careers based on apparent internal and external factors. Two questions guided this research: (1) What are high school African American males' perceptions of science careers? (2) What influences high school African American males' perceptions of science careers? This research was based on a pilot study in which African American college males perceived a selection of science careers along racial and gender lines. The follow-up investigation was conducted at Rockriver High School in Acorn County, and the participants were three college-bound African American males. The decision to choose males was based on the concept of occupational niching along gender lines. In biology, niching is defined as the role of a particular species regarding space and reproduction, and its interactions with other factors. During the seven-week period of the students' senior year, they met with the researcher to discuss their perceptions of science careers. An ethnographic approach was used to allow a richer and thicker narrative to occur. Critical theory was used to describe and interpret the voices of the participants from a social perspective. The data collected were analyzed using a constant comparative analysis technique. The participants revealed role models, negative stereotypes, peer pressure, social pressures, and misconceptions as some of the factors that influenced their perceptions of science careers. Results of this research suggest that by dispelling the misconceptions, educators can positively influence the attitudes and perceptions of

  12. Cradle to third life: An autobiography of an African-American science educator

    Science.gov (United States)

    Caruthers-Jackson, Sarah

    This inquiry used reflective autobiographical research to reveal my beliefs, values, and practices of science teaching by using participatory action research with two students of my science tutoring organization. Also, I conducted an ethnographic inquiry using African-American teachers to understand how my early schooling experiences influenced my beliefs, values, and science practices. I collected data for this inquiry from three African-American teachers through interview-conversation that were videotaped and audiotaped. In addition, I audiotaped two African-American students' tutoring practices along with students' and researcher's journals. The findings indicate that African-American teachers during the school years 1942-1954 used families, churches, and communities to secure teaching resources to provide equal education for their African-American students who received limited resources from the board of education. Also indicated was how African-American teachers instilled in their African-American students a level of motivation that remained with some African-American students for their future endeavors. This researcher's beliefs/values similar to those of her segregated teachers emerged from this action research. Researcher's additional beliefs/values arose out of emerging technologies in teaching science. However, I, as the researcher, believe that the origin of my beliefs/values occurred during those segregated, public school experiences at Monitor Schools during the school years 1942-1954.

  13. Evaluation of a health sciences internship for Latino and Native American library students.

    Keselman, Alla; Quasem, Sanjana; Kelly, Janice E; Dutcher, Gale A

    2016-10-01

    This paper presents a qualitative evaluation of a graduate-level internship for Latino and Native American library science students or students who are interested in serving those populations. The authors analyzed semi-structured interviews with thirteen internship program graduates or participants. The analysis suggests that the program increased participants' interest in health sciences librarianship and led to improved career opportunities, both in health sciences libraries and other libraries with health information programming. It also highlights specific factors that are likely to contribute to the strength of career pipeline programs aiming to bring Latino and Native American students and students who are interested in serving those communities into health librarianship. Exposing graduate-level interns to a broad range of health sciences librarianship tasks, including outreach to Latino and Native American communities and formal mentorship, is likely to maximize interns' interests in both health sciences librarianship and service to these communities.

    Miller, Stephania T; Akohoue, Sylvie A; Brooks, Malinda A

    2014-12-01

    African American women carry a disproportionate diabetes burden, yet there is limited information on strategies to identify outcomes women perceive as important intervention outcomes (patient-centered outcomes). This study presents a brief strategy to solicit these outcomes and to describe outcomes identified using the highlighted strategy. Thirty-four African-American women with type 2 diabetes were enrolled in group-based, diabetes/weight management interventions. A diabetes educator asked participants to write down their intervention expectations followed by verbal sharing of responses. Expectation-related themes were identified using an iterative, qualitative, team analytic approach based on audio-recorded responses. The majority of the expectation-related themes (6 of 10) were reflective of self-care education/management and weight loss-related patient-centered outcomes. The remaining themes were associated with desires to help others prevent or manage diabetes, reduce negative diabetes-related emotions, get rid of diabetes, and stop taking diabetes medications. This study adds to a limited body of knowledge regarding patient-centered outcomes among a group that experiences a disproportionate diabetes burden. Future work could include integrating outcomes that are less commonly addressed in diabetes-related lifestyle interventions (e.g., diabetes-related negative emotions), along with more commonly addressed outcomes (e.g., weight loss), to increase the patient-centeredness of the interventions.

  16. Emergence of the North American center of excellence for transportation equipment

    Directory of Open Access Journals (Sweden)

    Richard Gottschall

    2017-07-01

    Full Text Available Following the closure of Plattsburgh Air Force Base in 1995, the northeastern region of New York State faced a unique economic development challenge. In addition to the loss of the air base, the rural area suffers from urbanization and automation in manufacturing trends. While the quality of life is highly rated, population and job growth stagnate. Isolated geographically by Lake Champlain to the East, the Adirondack Mountains to the South and West, and long distances to southern economic centers in the state, the region has looked north of the Canadian border and positioned itself as "Montreal's US suburb". Economic developers have crafted bi-national agreements between regional organizations, improved cross-border infrastructure, and enhanced educational institutions for the purpose of attracting Canadian and international manufacturers to the region. In 2015, the North American Center of Excellence in Transportation Equipment was launched and six new companies joined the cluster, doubling its size and perhaps providing a base for further growth. Manufacturing jobs are likely to grow for the first time in more than 20-years. We use cluster theory to argue that this formation of companies may still be insufficient to catalyze cluster emergence and the desired goal of regional competitiveness. Moving forward in the crafting of regional economic development policy, we emphasize the importance of viewing the North American Center of Excellence for Transportation Equipment as a pre-emergent cluster in need of further support to reach its potential.

  17. Uncovering Black/African American and Latina/o students' motivation to learn science: Affordances to science identity development

    Science.gov (United States)

    Mahfood, Denise Marcia

    The following dissertation reports on a qualitative exploration that serves two main goals: (1) to qualitatively define and highlight science motivation development of Black/African American and Latina/o students as they learn science in middle school, high school, and in college and (2) to reveal through personal narratives how successful entry and persistence in science by this particular group is linked to the development of their science identities. The targeted population for this study is undergraduate students of color in science fields at a college or university. The theoretical frameworks for this study are constructivist theory, motivation theory, critical theory, and identity theories. The methodological approach is narrative which includes students' science learning experiences throughout the course of their academic lives. I use The Science Motivation Questionnaire II to obtain baseline data to quantitatively assess for motivation to learn science. Data from semi-structured interviews from selected participants were collected, coded, and configured into a story, and emergent themes reveal the important role of science learning in both informal and formal settings, but especially in informal settings that contribute to better understandings of science and the development of science identities for these undergraduate students of color. The findings have implications for science teaching in schools and teacher professional development in science learning.

  18. An examination of the association between demographic and educational factors and African American achievement in science

    Science.gov (United States)

    Cottledge, Michael Christopher

    Objective of the Study: The objective of this research study was to investigate whether an association exists between teacher demographic factors (years of teaching experience and gender), 2 educational factors (certification type and certification pathway) and the percent passing rate of tenth grade African American male students on the 2010 science TAKS. Answers to the following questions were sought: 1. Is there an association between teacher demographic factors and the percent passing rate of their tenth grade African American male students on the 2010 science TAKS? 2. Is there an association between teacher educational factors and the percent passing rate of their tenth grade African American male students on the 2010 science TAKS? 3. Is there an association between teacher demographic factors, educational factors and the percent passing rate of their tenth grade African American male students on the 2010 science TAKS? Status of the Question: According to the Bureau of Labor Statistics (BLS), science and engineering jobs in the U.S. have increased steadily over recent years and by the year 2016 the number of STEM (Science, Technology, Engineering and Math) jobs will have grown by more than 21 percent. This increase in science and engineering jobs will double the growth rate of all other workforce sectors combined. The BLS also reports that qualified minority applicants needed to fill these positions will be few and far between. African Americans, Latinos, and other minorities constitute 24 percent of the U.S. population but only 13 percent of college graduates and just 10 percent of people with college degrees who work in science and engineering (Education Trust, 2009). Drawing on the above information, I proposed the following hypotheses to the research questions: H01: There will be no significant statistical association between the demographic factors teacher gender and years of teaching experience and the percent passing rate of their tenth grade African

    2017-02-01

    To analyze characteristics of type II odontoid fracture (TII-OF), including clinical and radiographic factors, that influence surgical planning in 8 Latin American centers. Retrospective chart review was performed of 88 patients with TII-OF between 2004 and 2015 from 8 Latin American centers. Parameters studied included 1) demographic data and causes of TII-OF, 2) clinical and neurologic presentation, 3) characteristics of fracture (degree of odontoid displacement, displacement of odontoid relative to C2 body, anatomy of fracture line, distance between fragments, presence of comminution, contact area between odontoid and C2 body), 4) type of treatment, and 5) clinical and radiographic outcome. Bone fusion was assessed using computed tomography. Mean patient age was 45.33 years ± 23.54; 78.4% of patients were male. Surgery was the primary treatment in 65 patients (73.8%), with an anterior approach in 64.6%. Surgery was usually preferred in patients with posterior or horizontal oblique fracture lines, local pain, and a smaller bone contact surface between the odontoid and the body of C2. A posterior approach was chosen when distance between the fractured bone fragments was >2 mm or after failed conservative or anterior odontoid screw treatment in a symptomatic patient. The treatment of choice for TII-OF in 8 Latin American trauma centers was surgery through an anterior approach using screw fixation. Posterior segmental C1-C2 fixation was indicated when distance between bone fragments was >2 mm and in symptomatic patients with nonunion. Copyright © 2016 Elsevier Inc. All rights reserved.

    Kim, Sun Young; Nehm, Ross H.

    2011-01-01

    Despite a few international comparisons of the evolutionary beliefs of the general public, comparatively less research has focused on science teachers. Cross-cultural studies offer profitable opportunities for exploring the interactions among knowledge and belief variables in regard to evolution in different socio-cultural contexts. We investigated the evolutionary worldviews of pre-service science teachers from Asia (specifically South Korea), a region often excluded from international comparisons. We compared Korean and American science teachers': (1) understandings of evolution and the nature of science, and (2) acceptance of evolution in order to elucidate how knowledge and belief relationships are manifested in different cultural contexts. We found that Korean science teachers exhibited 'moderate' evolutionary acceptance levels comparable to or lower than American science teacher samples. Gender was significantly related to Korean teachers' evolution content knowledge and acceptance of evolution, with female Christian biology teachers displaying the lowest values on all measures. Korean science teachers' understandings of nature of science were significantly related to their acceptance and understanding of evolution; this relationship appears to transcend cultural boundaries. Our new data on Korean teachers, combined with studies from more than 20 other nations, expose the global nature of science teacher ambivalence or antipathy toward evolutionary knowledge.

    We surveyed ketogenic diet centers in North America about their practices surrounding the ketogenic diet. An internet survey was disseminated via REDCap(©) to North American ketogenic diet centers identified from the Charlie Foundation and Ketocal(©) websites. Fifty-six centers responded. In addition to physicians, nurses and dieticians, ketogenic teams included social workers (39%), feeding specialists (14%), educational liaisons (4%), psychologists (5%), and pharmacists (36%). A child attending school (2%), non-English speaking family (19%), single-parent family (0%), and oral feeding (6%) were rarely considered barriers. Overall, the diet was considered the first or second (0%), third or fourth (67%), fifth or sixth (29%), and last resort treatment (4%) by centers. It was considered the first or second treatment for GLUT1 disease (86%) and third or fourth for Dravet (63%), West (71%), and Doose (65%) syndromes. Ketogenic diet is no longer a last resort option. Traditional barriers do not influence its use. © The Author(s) 2014.

    Full Text Available The purpose of this study is to determine the fundamental problems of science gifted teachers (SG/Ts who teach Turkish gifted children (G/C and compare it with the international milieu. Turkish G/C are taught in different educational contexts named “Science and Art Centers” (SACs in which better opportunities are presented for them. In this project, field observations were done at three of the SACs in Turkey - in Bayburt, Sinop, and Trabzon - and, semi-structured interviews were conducted with each of ten SG/Ts who work in these centers by one of the researchers. Data analysis showed that SG/Ts do not perceive their duties holistically and feel they need help with measurement and assessment techniques, modern learning theories, planning and implementation of a research project, questioning techniques and using laboratory-based methods for G/C. Moving from the research data, it is suggested that in service education courses, which include the above issues, should be organized for the SG/Ts and they should be encouraged to use an action research approach in teaching G/C in SACs.

    2010-01-01

    Minerals in the environment and products manufactured from mineral materials are all around us and we use and come into contact with them every day. They impact our way of life and the health of all that lives. Minerals are critical to the Nation's economy and knowing where future mineral resources will come from is important for sustaining the Nation's economy and national security. The U.S. Geological Survey (USGS) Mineral Resources Program (MRP) provides scientific information for objective resource assessments and unbiased research results on mineral resource potential, production and consumption statistics, as well as environmental consequences of mining. The MRP conducts this research to provide information needed for land planners and decisionmakers about where mineral commodities are known and suspected in the earth's crust and about the environmental consequences of extracting those commodities. As part of the MRP scientists of the Western Mineral and Environmental Resources Science Center (WMERSC or 'Center' herein) coordinate the development of national, geologic, geochemical, geophysical, and mineral-resource databases and the migration of existing databases to standard models and formats that are available to both internal and external users. The unique expertise developed by Center scientists over many decades in response to mineral-resource-related issues is now in great demand to support applications such as public health research and remediation of environmental hazards that result from mining and mining-related activities. Western Mineral and Environmental Resources Science Center Results of WMERSC research provide timely and unbiased analyses of minerals and inorganic materials to (1) improve stewardship of public lands and resources; (2) support national and international economic and security policies; (3) sustain prosperity and improve our quality of life; and (4) protect and improve public health, safety, and environmental quality.

  14. African-American males in computer science---Examining the pipeline for clogs

    Science.gov (United States)

    Stone, Daryl Bryant

    The literature on African-American males (AAM) begins with a statement to the effect that "Today young Black men are more likely to be killed or sent to prison than to graduate from college." Why are the numbers of African-American male college graduates decreasing? Why are those enrolled in college not majoring in the science, technology, engineering, and mathematics (STEM) disciplines? This research explored why African-American males are not filling the well-recognized industry need for Computer Scientist/Technologists by choosing college tracks to these careers. The literature on STEM disciplines focuses largely on women in STEM, as opposed to minorities, and within minorities, there is a noticeable research gap in addressing the needs and opportunities available to African-American males. The primary goal of this study was therefore to examine the computer science "pipeline" from the African-American male perspective. The method included a "Computer Science Degree Self-Efficacy Scale" be distributed to five groups of African-American male students, to include: (1) fourth graders, (2) eighth graders, (3) eleventh graders, (4) underclass undergraduate computer science majors, and (5) upperclass undergraduate computer science majors. In addition to a 30-question self-efficacy test, subjects from each group were asked to participate in a group discussion about "African-American males in computer science." The audio record of each group meeting provides qualitative data for the study. The hypotheses include the following: (1) There is no significant difference in "Computer Science Degree" self-efficacy between fourth and eighth graders. (2) There is no significant difference in "Computer Science Degree" self-efficacy between eighth and eleventh graders. (3) There is no significant difference in "Computer Science Degree" self-efficacy between eleventh graders and lower-level computer science majors. (4) There is no significant difference in "Computer Science Degree

    The Life Sciences Project Division (LSPD) at JSC, which manages human life sciences flight experiments for the NASA Life Sciences Division, augmented its Life Sciences Data System (LSDS) in support of the Spacelab Life Sciences-2 (SLS-2) mission, October 1993. The LSDS is a portable ground system supporting Shuttle, Spacelab, and Mir based life sciences experiments. The LSDS supports acquisition, processing, display, and storage of real-time experiment telemetry in a workstation environment. The system may acquire digital or analog data, storing the data in experiment packet format. Data packets from any acquisition source are archived and meta-parameters are derived through the application of mathematical and logical operators. Parameters may be displayed in text and/or graphical form, or output to analog devices. Experiment data packets may be retransmitted through the network interface and database applications may be developed to support virtually any data packet format. The user interface provides menu- and icon-driven program control and the LSDS system can be integrated with other workstations to perform a variety of functions. The generic capabilities, adaptability, and ease of use make the LSDS a cost-effective solution to many experiment data processing requirements. The same system is used for experiment systems functional and integration tests, flight crew training sessions and mission simulations. In addition, the system has provided the infrastructure for the development of the JSC Life Sciences Data Archive System scheduled for completion in December 1994.

  16. Academic attainment and the high school science experiences among high-achieving African American males

    Trice, Rodney Nathaniel

    This study examines the educational experiences of high achieving African American males. More specifically, it analyzes the influences on their successful navigation through high school science. Through a series of interviews, observations, questionnaires, science portfolios, and review of existing data the researcher attempted to obtain a deeper understanding of high achieving African American males and their limitations to academic attainment and high school science experiences. The investigation is limited to ten high achieving African American male science students at Woodcrest High School. Woodcrest is situated at the cross section of a suburban and rural community located in the southeastern section of the United States. Although this investigation involves African American males, all of whom are successful in school, its findings should not be generalized to this nor any other group of students. The research question that guided this study is: What are the limitations to academic attainment and the high school science experiences of high achieving African American males? The student participants expose how suspension and expulsion, special education placement, academic tracking, science instruction, and teacher expectation influence academic achievement. The role parents play, student self-concept, peer relationships, and student learning styles are also analyzed. The anthology of data rendered three overarching themes: (1) unequal access to education, (2) maintenance of unfair educational structures, and (3) authentic characterizations of African American males. Often the policies and practices set in place by school officials aid in creating hurdles to academic achievement. These policies and practices are often formed without meaningful consideration of the unintended consequences that may affect different student populations, particularly the most vulnerable. The findings from this study expose that high achieving African American males face major

    While falls are highly prevalent and costly for older adults, little is known about falls for Asian Americans. Using a custom, evidence-based, bilingual fall risk assessment and management tool, our study examined the prevalence of falls among older Chinese-speaking patients at a community health center. We identified the risks for falls and explored an association of fall risk with emergency room (ER) and hospital use in this population. The setting was at a community health center in Oakland, CA. Participants included 839 older Asian American adults (ages 65-80 years) who spoke Cantonese/Mandarin. Primary care clinic staff administered a fall risk assessment and management tool at the time of clinic visits to assess patients' risk factors for falls. Of the total, 173 (20.6%) reported having fallen in the past year, with women comprising a majority (71.7%). 362 patients in the cohort (43.1%) reported fear of falling. For the subset of Medicaid managed care patients (n = 455, 54.3% of total) for whom we were able to obtain ER and hospital utilization data, 31 patients (14.5%) who reported a fall risk had an ER/hospital episode compared to 15 (6.2%) of those who did not self-report fall risks (statistically significant, p cultural competence to focus on Asian American older adults, can help establish the prevalence of falls in this understudied population and effectively identify those at higher risk for falls and subsequent ER/hospital utilization. More research is needed to understand the risk and impacts of falls in understudied populations and identify ways to prevent these costly falls.

    Full Text Available The objective of this article is to present a panorama of the journalistic coverage of science and technology themes in Latin America, taking as a case study 12 newspapers of signifcant impact in the region, involving nine countries. We collected the stories published in the science section from January to April 2006, and analyzed them based on the constructed week methodology and using quantitative tools. In total, our sample amounted to 681 stories. Among our fndings, we observed an important presence of medicine and health issues as main topics of the stories. National science has space in the newspapers, although less than scientifc results from developed countries. Benefts are stressed in the stories, while a low level of controversies is observed. Scientists are the main source for the journalists, with a low representation of the former in stereotyped images in most of the newspapers.

  1. Engineering success: Persistence factors of African American doctoral recipients in engineering and applied science

    Science.gov (United States)

    Simon, Tiffany Monique

    The purpose of this qualitative study was to identify factors that influence African Americans to pursue and complete doctoral degrees in engineering and applied science disciplines. Critical race theory (CRT), two models of doctoral student persistence, and graduate student persistence literature guided the conceptual framework of this study. In-depth and focus group interviews were conducted to learn the key factors that positively impacted the persistence of 19 African Americans who earned doctoral degrees in engineering and applied science. The following two factors were found to significantly contribute to the decision to pursue the doctorate: encouragement from others and participation in a research or internship program. Key factors impacting doctoral degree completion included: peer support, faculty adviser support, support from university administrators, and family support. In addition to identifying factors that influenced 19 African Americans to pursue and complete doctoral degrees in engineering and applied science, this study was about the importance of diversity and inclusion of multiple perspectives in education research and scholarship. To this end, the study served to promote and include the expert knowledge of African American doctoral degree recipients in engineering and applied science in the scholarly discourse on the issue of low participation rates of African Americans in engineering and applied science disciplines. Such knowledge will challenge traditional views on this issue and hopefully inspire new ways of addressing and remedying this issue. With African Americans and other minority populations growing at an exponential rate, people of color are quickly becoming the majority in key states across the nation. Therefore, it is imperative that all Americans have an opportunity to develop skills necessary to compete for professional positions in the science and engineering workforce. This mandate is required for the United States to maintain

  2. Teachers' Perception of African American Middle School Girls' Interest in Mathematics and Science

    Science.gov (United States)

    Best, Bonnie M.

    Research into African American female underrepresentation in science, technology, engineering, and mathematics (STEM) fields has become an area of interest due to the fact that a majority of African American middle school females do not possess the high levels of mathematics and science knowledge because of social and cultural barriers both inside and outside school that challenge their academic success. The purpose of this qualitative interpretative phenomenological study was to explore teachers' shared, lived experiences of teaching mathematics and science to African American middle school girls. Delgado and Stefancic's critical race theory, Pratt-Clarke's critical race feminism, and Baker-Miller's relational-cultural theory were used to guide this study. Research questions focused on the perceptions and experiences of teachers' lived experiences teaching mathematics and science to African American middle school females. Criterion, purposive, and maximum variation sampling techniques were used to recruit 10 teachers who have 3 or more years' experience teaching African American middle school girls. Semistructured face-to-face interviews were the primary data collection source. First cycle and second cycle coding methods were used to support the analysis of this study. Findings suggest that there is a connection between a positive student-teacher relationship and academic success. The results of this study contribute to positive social change by providing empirical evidence policymakers and teachers can use to improve the mathematics and science instruction and practices that are needed to meet the needs of African American middle school females and reduce the underrepresentation and underachievement of African American females in mathematics and science.

  10. A critical hermeneutic study: Third grade elementary African American students' views of the nature of science

    Science.gov (United States)

    Walls, Leon

    Nature of Science is one of the most fundamental aspects of understanding science. How different cultures, races and ethnicities see and interpret science differently is critical. However, the NOS views specific to African American teachers and learners have gone largely unresearched. The views of a purposeful sample of African American third grade children reported in this study contribute to efforts to make science equitable for all students. Conducted in two Midwest urban settings, within the students' regular classrooms, three instruments were employed: Views of Nature of Science Elementary (an interview protocol), Elementary Draw a Scientist Test (a drawing activity supplemented by an explicating narrative), and Identify a Scientist (a simple select-a-photo technique supported by Likert-measured sureness). The responses provided by twenty-three students were coded using qualitative content analysis. The findings are represented in three main categories: Science - is governed by experimentation, invention and discovery teach us about the natural world, school is not the only setting for learning science; Scientists - intelligent, happy, studious men and women playing multiple roles, with distinct physical traits working in laboratories; Students - capable users and producers of science and who view science as fun. This study advocates for: use of such instruments for constant monitoring of student views, using the knowledge of these views to construct inquiry based science lessons, and increased research about students of color.

  11. Achieving equity through critical science agency: An ethnographic study of African American students in a health science career academy

    Science.gov (United States)

    Haun-Frank, Julie

    The purpose of this study was to examine the potential of a High School Health Science Career Academy to support African American students' science career trajectories. I used three key theoretical tools---critical science agency (Basu, 2007; Calabrese Barton & Tan, 2008), power (Nespor, 1994), and cultural production (Carlone, 2004; Eisenhart & Finkel, 1998) to highlight the intersections between the career trajectory implied by the Academy (its curriculum, classroom activities, and clinical experiences) and the students' pursued career trajectories. Data was collected over five months and included individual student interviews, group interviews, parent and administrator interviews, field notes from a culminating medical course and clinical internship, and Academy recruitment documents. The results of this study suggest that participants pursued a health science career for altruistic purposes and the Academy was a resource they drew upon to do so. However, the meanings of science and science person implied by the Academy hindered the possibility for many participants' to advance their science career trajectories. While the Academy promised to expose students to a variety of high-status health care roles, they were funneled into feminine, entry-level positions. This study adds to previous underrepresentation literature by contextualizing how identity-related factors influence African American students' career attainment.

  12. Abandoning evolution. The forgotten history of antievolution activism and the transformation of American social science.

    Science.gov (United States)

    Lienesch, Michael

    2012-12-01

    From its inception, antievolution activism has been aimed not only at the natural sciences but also, and almost as often, at the social sciences. Although almost entirely overlooked by scholars, this activism played a significant part in the development of American social science in the early twentieth century. Analyzing public writings and private papers of antievolution activists, academic social scientists, and university officials from the 1920s, this essay recalls this forgotten history, showing how antievolution activism contributed to the abandonment of evolutionary theory and the adoption of a set of secular, scientific, and professional characteristics that have come to define much of modern social science.

    2010-06-01

    This essay examines the experiences of about five thousand Chinese students/scientists in the United States after the Communist takeover of mainland China in 1949. These experiences illustrate the often hidden transnational movements of people, instruments, and ideas in science and technology across the Iron Curtain during the Cold War. I argue that those hundreds who returned to China represented a partial "Americanization" of Chinese science and technology, while the rest of the group staying in the United States contributed to a transnationalization of the American scientific community.

  5. The Black Cultural Ethos and science teachers' practices: A case study exploring how four high school science teachers meet their African American students' needs in science

    Science.gov (United States)

    Strachan, Samantha L.

    The underachievement of African American students in science has been a persistent problem in science education. The achievement patterns of African American students indicate that researchers must take a closer look at the types of practices that are being used to meet these students' needs in science classrooms. Determining why science teachers decide to employ certain practices in their classrooms begins with a careful examination of teachers' beliefs as well as their instructional approaches. The purpose of this study was to explore four urban high school science teachers' beliefs about their African American students' learning needs and to investigate how these teachers go about addressing students' needs in science classrooms. This research study also explored the extent to which teachers' practices aligned with the nine dimensions of an established cultural instructional theory, namely the Black Cultural Ethos. Qualitative research methods were employed to gather data from the four teachers. Artifact data were collected from the teachers and they were interviewed and observed. Believing that their students had academic-related needs as well as needs tied to their learning preferences, the four science teachers employed a variety of instructional strategies to meet their students where they were in learning. Overall, the instructional strategies that the teachers employed to meet their students' needs aligned with five of the nine tenets of the Black Cultural Ethos theory.

    Many advances in health care fail to reach patients. Implementation science is the study of novel approaches to mitigate this evidence-to-practice gap. The American Thoracic Society (ATS) created a multidisciplinary ad hoc committee to develop a research statement on implementation science in pulmonary, critical care, and sleep medicine. The committee used an iterative consensus process to define implementation science and review the use of conceptual frameworks to guide implementation science for the pulmonary, critical care, and sleep community and to explore how professional medical societies such as the ATS can promote implementation science. The committee defined implementation science as the study of the mechanisms by which effective health care interventions are either adopted or not adopted in clinical and community settings. The committee also distinguished implementation science from the act of implementation. Ideally, implementation science should include early and continuous stakeholder involvement and the use of conceptual frameworks (i.e., models to systematize the conduct of studies and standardize the communication of findings). Multiple conceptual frameworks are available, and we suggest the selection of one or more frameworks on the basis of the specific research question and setting. Professional medical societies such as the ATS can have an important role in promoting implementation science. Recommendations for professional societies to consider include: unifying implementation science activities through a single organizational structure, linking front-line clinicians with implementation scientists, seeking collaborations to prioritize and conduct implementation science studies, supporting implementation science projects through funding opportunities, working with research funding bodies to set the research agenda in the field, collaborating with external bodies responsible for health care delivery, disseminating results of implementation

    Transforming science learning through student-centered instruction that engages students in a variety of scientific practices is central to national science-teaching reform efforts. Our study employed a large-scale, randomized-cluster experimental design to compare the effects of student-centered and teacher-centered approaches on elementary school students' understanding of space-science concepts. Data included measures of student characteristics and learning and teacher characteristics and fidelity to the instructional approach. Results reveal that learning outcomes were higher for students enrolled in classrooms engaging in scientific practices through a student-centered approach; two moderators were identified. A statistical search for potential causal mechanisms for the observed outcomes uncovered two potential mediators: students' understanding of models and evidence and the self-efficacy of teachers.

    Based on historical data, a study was made of the contributions of Spanish authors to the most prestigious radiological journals, for the purpose of assessing the impact of Spanish radiologists on the international level. The articles written by authors working in Spanish centers that were printed in the American Journal of Roentgenology between January 1975 and May 2000 were collected manually and the citations introduced into a database. A Medline search was then carried out to assess the rate of publication in U. S. radiological journals of authors from countries other than Spain and of five authors of Spanish origin working in the United States. The results demonstrate a recent, progressive increase in the number of articles published by Spanish authors in these journals, similar to that observed in a number of European countries. This production is concentrated in a few hospitals, although the source of articles has diversified somewhat in recent years, at the expense of medium-sized hospitals. There is a predominance of short works and those produced by a single center. There is clear evidence of considerable scientific activity, probably the most intense level reached in Spanish Medical Radiology over the past century. (Author) 115 refs

    2009-01-01

    The education and training of the next generation of scientists who will form the user base for the Spallation Neutron Source (SNS) remains a significant issue for the future success of this national facility. These scientists will be drawn from a wide variety of disciplines (physics, chemistry, biology, and engineering) and therefore the development of an effective interdisciplinary training program represents a significant challenge. In addition, effective test facilities to develop the full potential of pulsed neutron sources for science do not exist. Each of these problems represents a significant hurdle for the future health of neutron science in this country. An essential part of the solution to both problems is to get neutron sources of useful intensities into the hands of researchers and students at universities, where faculty can teach students about neutron production and the utility of neutrons for solving scientific problems. Due to a combination of developments in proton accelerator technology, neutron optics, cold neutron moderators, computer technology, and small-angle neutron scattering (SANS) instrumentation, it is now technically possible and cost effective to construct a pulsed cold neutron source suitable for use in a university setting and devoted to studies of nano structures in the fields of materials science, polymers, microemulsions, and biology. Such a source, based on (p,n) reactions in light nuclei induced by a few MeV pulsed proton beam coupled to a cold neutron moderator, would also be ideal for the study of a number of technical issues which are essential for the development of neutron science such as cold and perhaps ultracold neutron moderators, neutron optical devices, neutron detector technology, and transparent DAQ/user interfaces. At the Indiana University Cyclotron Facility (IUCF) we possess almost all of the required instrumentation and expertise to efficiently launch the first serious attempt to develop an intense pulsed cold

    Parker, Ashley Dawn

    This research seeks to understand the experiences of African American female undergraduates in STEM. It investigates how familial factors and science identity formation characteristics influence persistence in STEM while considering the duality of African American women's status in society. This phenomenological study was designed using critical race feminism as the theoretical framework to answer the following questions: 1) What role does family play in the experiences of African American women undergraduate STEM majors who attended two universities in the UNC system? 2) What factors impact the formation of science identity for African American women undergraduate STEM majors who attended two universities in the UNC system? Purposive sampling was used to select the participants for this study. The researcher conducted in-depth interviews with 10 African American female undergraduate STEM major from a predominantly White and a historically Black institution with the state of North Carolina public university system. Findings suggest that African American families and science identity formation influence the STEM experiences of the African American females interviewed in this study. The following five themes emerged from the findings: (1) independence, (2) support, (3) pressure to succeed, (4) adaptations, and (5) race and gender. This study contributes to the literature on African American female students in STEM higher education. The findings of this study produced knowledge regarding policies and practices that can lead to greater academic success and persistence of African American females in higher education in general, and STEM majors in particular. Colleges and universities may benefit from the findings of this study in a way that allows them to develop and sustain programs and policies that attend to the particular concerns and needs of African American women on their campuses. Finally, this research informs both current and future African American female

    Neutron imaging is an incredibly powerful tool for non-destructive sample characterization and materials science. Neutron tomography is one technique that results in a three-dimensional model of the sample, representing the interaction of the neutrons with the sample. This relies both on reliable data acquisition and on image processing after acquisition. Over the course of the project, the focus has changed from the former to the latter, culminating in a large-scale reconstruction of a meter-long fossilized skull. The full reconstruction is not yet complete, though tools have been developed to improve the speed and accuracy of the reconstruction. This project helps to improve the capabilities of LANSCE and LANL with regards to imaging large or unwieldy objects.

    2016-12-01

    Data indicate that females and ethnic/race minority groups are underrepresented in the science and engineering workforce calling for innovative strategies to engage and retain them in science education and careers. This study reports on the development, delivery, and outcomes of a culturally driven science, technology, engineering, mathematics (STEM) program, iSTEM, aimed at increasing engagement in STEM learning among Native American 3rd-8th grade students. A culturally relevant theoretical framework, Funds of Knowledge, informs the iSTEM program, a program based on the contention that the synergistic effect of a hybrid program combining two strategic approaches (1) in-school mentoring and (2) out-of-school informal science education experiences would foster engagement and interest in STEM learning. Students are paired with one of three types of mentors: Native American community members, university students, and STEM professionals. The iSTEM program is theme based with all program activities specifically relevant to Native people living in southern Arizona. Student mentees and mentors complete interactive flash STEM activities at lunch hour and attend approximately six field trips per year. Data from the iSTEM program indicate that the program has been successful in engaging Native American students in iSTEM as well as increasing their interest in STEM and their science beliefs.

  20. "I am Not a Statistic": Identities of African American Males in Advanced Science Courses

    Johnson, Diane Wynn

    The United States Bureau of Labor Statistics (2010) expects new industries to generate approximately 2.7 million jobs in science and technology by the year 2018, and there is concern as to whether there will be enough trained individuals to fill these positions. A tremendous resource remains untapped, African American students, especially African American males (National Science Foundation, 2009). Historically, African American males have been omitted from the so called science pipeline. Fewer African American males pursue a science discipline due, in part; to limiting factors they experience in school and at home (Ogbu, 2004). This is a case study of African American males who are enrolled in advanced science courses at a predominantly African American (84%) urban high school. Guided by expectancy-value theory (EVT) of achievement related results (Eccles, 2009; Eccles et al., 1983), twelve African American male students in two advanced science courses were observed in their science classrooms weekly, participated in an in-depth interview, developed a presentation to share with students enrolled in a tenth grade science course, responded to an open-ended identity questionnaire, and were surveyed about their perceptions of school. Additionally, the students' teachers were interviewed, and seven of the students' parents. The interview data analyses highlighted the important role of supportive parents (key socializers) who had high expectations for their sons and who pushed them academically. The students clearly attributed their enrollment in advanced science courses to their high regard for their science teachers, which included positive relationships, hands-on learning in class, and an inviting and encouraging learning environment. Additionally, other family members and coaches played important roles in these young men's lives. Students' PowerPoint(c) presentations to younger high school students on why they should take advanced science courses highlighted these

    The Lujan Neutron Scattering Center (Lujan Center) at LANSCE is a designated National User Facility for neutron scattering and nuclear physics studies with pulsed beams of moderated neutrons (cold, thermal, and epithermal). As one of five experimental areas at the Los Alamos Neutron Science Center (LANSCE), the Lujan Center hosts engineers, scientists, and students from around the world. The Lujan Center consists of Experimental Room (ER) 1 (ERl) built by the Laboratory in 1977, ER2 built by the Office of Basic Energy Sciences (BES) in 1989, and the Office Building (622) also built by BES in 1989, along with a chem-bio lab, a shop, and other out-buildings. According to a 1996 Memorandum of Agreement (MOA) between the Defense Programs (DP) Office of the National Nuclear Security Agency (NNSA) and the Office of Science (SC, then the Office of Energy Research), the Lujan Center flight paths were transferred from DP to SC, including those in ERI. That MOA was updated in 2001. Under the MOA, NNSA-DP delivers neutron beam to the windows of the target crypt, outside of which BES becomes the 'landlord.' The leveraging nature of the Lujan Center on the LANSCE accelerator is a substantial annual leverage to the $11 M BES operating fund worth approximately $56 M operating cost of the linear accelerator (LINAC)-in beam delivery.

    Gargus, Gerald Vincent

    This investigation represents an in-depth understanding of teacher professional development at the Alexander Science Center School, a dependent charter museum school established through a partnership between the California Science Center and Los Angeles Unified School District. Three methods of data collection were used. A survey was distributed and collected from the school's teachers, resulting in a prioritized list of teacher professional development needs, as well as a summary of teachers' opinions about the school's existing professional development program. In addition, six key stakeholders in the school's professional development program were interviewed for the study. Finally, documents related to the school's professional development program were analyzed. Data collected from the interviews and documents were used to develop an understand various components of the Alexander Science Center School's professional development program. Teachers identified seven areas that had a high-priority for future professional development including developing skills far working with below-grade-level students, improving the analytical skills of student in mathematics, working with English Language Learners, improving students' overall reading ability levels, developing teachers' content-area knowledge for science, integrating science across the curriculum, and incorporating hands-on activity-based learning strategies to teach science. Professional development needs identified by Alexander Science Center School teachers were categorized based on their focus on content knowledge, pedagogical content knowledge, or curricular knowledge. Analysis of data collected through interviews and documents revealed that the Alexander Science Center School's professional development program consisted of six venues for providing professional development for teachers including weekly "banked time" sessions taking place within the standard school day, grade-level meetings, teacher support

    Teresa Castelao-Lawless

    2001-01-01

    Full Text Available Students of history and philosophy of science courses at my University are either naïve robust realists or naïve relativists in relation to science and technology. The first group absorbs from culture stereotypical conceptions, such as the value-free character of the scientific method, that science and technology are impervious to history or ideology, and that science and religion are always at odds. The second believes science and technology were selected arbitrarily by ideologues to have privileged world views of reality to the detriment of other interpretations. These deterministic outlooks must be challenged to make students aware of the social importance of their future roles, be they as scientists and engineers or as science and technology policy decision makers. The University as Decision Center (DC not only reproduces the social by teaching standard solutions to well-defined problems but also provides information regarding conflict resolution and the epistemological, individual, historical, social, and political mechanisms that help create new science and technology. Interdisciplinary research prepares students for roles that require science and technology literacy, but raises methodological issues in the context of the classroom as it increases uncertainty with respect to apparently self-evident beliefs about scientific and technological practices.

    Bondima, Michelle Harris

    This ethnographic in nature study explores how two middle school science teachers who have classes populated by urban African Americans teach their students and how their students perceive their teaching. Since urban African American students continue to perform lower than desired on measures of science achievement, there is an urgent need to understand what pedagogical methodologies assist and hinder urban African American students in achieving higher levels of success in science. A pedagogical methodology that theorists posit assists subordinated school populations is culturally responsive pedagogy. Culturally responsive pedagogy is defined as a teaching methodology concerned with preparing students to question inequality, racism, and injustice. Teachers who use culturally responsive pedagogy respect the culture students bring to the class, and require that the teachers willingly do whatever is necessary to educate students (Nieto, 2000). The teacher participants were two female African Americans who were identified by their school supervisors as being highly effective with urban African American students. The researcher presented the teachers in separate case studies conducted over a data collection period of nine months. Data were collected by participant observation, interviews, and artifact collection. Data were analyzed by application of grounded theory techniques. Findings of the teachers' (and the students') beliefs about pedagogy that both assisted and hindered the students' performance in science were reported in a rich and nuanced storytelling manner based on multiple perspectives (teachers', students', and the researcher's). Pedagogical methodologies that the teachers used that assisted their students were the use of cultural metaphors and images in science and applications of motivational techniques that encouraged a nurturing relationship between the teacher and her students. Pedagogical methodologies that hindered students varied by teacher

  9. African American eighth-grade female students' perceptions and experiences as learners of science literacy

    Science.gov (United States)

    Crim, Sharan R.

    The National Assessment of Educational Progress (2000) reports an achievement gap between male and female students and majority and minority students in science literacy. Rutherford and Algren (2000) describe a scientifically literate person as one who is aware that science, mathematics, and technology are interdependent human enterprises with strengths and limitations; understands key concepts and principles of science; is familiar with the natural world and recognizes both its diversity and unity; and uses scientific knowledge and scientific ways of thinking for individual and social purposes. The purpose of this qualitative case study research was to investigate African American eighth grade female students' perceptions and experiences as learners of science literacy. A social learning theory (Bandura, 1986) and constructivist theory (Vygotsky, 1977) served as a guide for the researcher. Two questions were explored: (1) What are African American eighth grade female students' perceptions and experiences as learners of science literacy? (2) In what ways do the perceptions and experiences of African American eighth grade female students influence their learning of science literacy? Purposeful sampling (Merriam, 1998) was used with four African American eighth grade female students selected as participants for the study. Data collection and analysis occurred between February and August in a single year. Data sources included an open-ended questionnaire, two in-depth interviews with each participant (Seidman, 1991); classroom observations, participant reflective journals, student artifacts, and a researcher's log. Data were analyzed through the constant comparative method (Glaser & Strauss, 1967), and richly descriptive participant portraits and qualitative case studies (Merriam, 1998) were used to report the findings. Three themes emerged from the study that positively affected the perceptions and experiences of African American eighth grade female students as

    The purpose of this study was to determine how North American dental students are taught neuroscience during their preclinical dental education. This survey represents one part of a larger research project, the Basic Science Survey Series for Dentistry, which covers all of the biomedical science coursework required of preclinical students in North American dental schools. Members of the Section on Anatomical Sciences of the American Dental Education Association assembled, distributed, and analyzed the neuroscience survey, which had a 98.5 percent response from course directors of the sixty-seven North American dental schools. The eighteen-item instrument collected demographic data on the course directors, information on the content in each course, and information on how neuroscience content is presented. Findings indicate that 1) most neuroscience instruction is conducted by non-dental school faculty members; 2) large content variability exists between programs; and 3) an increase in didactic instruction, integrated curricula, and use of computer-aided instruction is occurring. It is anticipated that the information derived from the survey will help guide neuroscience curricula in dental schools and aid in identifying appropriate content.

    For more that 20 years, the Global Learning and Observations to Benefit the Environment (GLOBE) Program has sought to increase environment literacy in students by involving them in the process of data collection and scientific research. In 2016, the program expanded to accept observations from citizen scientists of all ages through a relatively simple app. Called GLOBE Observer, the new program aims to help participants feel connected to a global community focused on advancing the scientific understanding of Earth system science while building climate literacy among participants and increasing valuable environmental data points to expand both student and scientific research. In October 2016, GLOBE Observer partnered with the Association of Science & Technology Centers (ASTC) in an international science experiment in which museums and patrons around the world collected cloud observations through GLOBE Observer to create a global cloud map in support of NASA satellite science. The experiment was an element of the International Science Center and Science Museum Day, an event planned in partnership with UNESCO and ASTC. Museums and science centers provided the climate context for the observations, while GLOBE Observer offered a uniform experience and a digital platform to build a connected global community. This talk will introduce GLOBE Observer and will present the results of the experiment, including evaluation feedback on gains in climate literacy through the event.

    2015-10-30

    Group violence among Latin American immigrant youth has led to ongoing debates in political, legal, and media circles, yet none of those many perspectives has arrived at a solid, empirically supported definition for the phenomenon. This study aims to explore the relationship between the immigrant experience and violent group behavior in youths from Latin America serving prison sentences in Justice Enforcement Centers in the Community of Madrid. Semi-structured interviews were conducted with 19 juveniles, and content analysis was applied to the resulting transcripts, employing Grounded Theory to create an axial codification of intra- and inter-categorical contents, and Delphi panels for quality control. The research team delved into 62 topics, addressing participants' perceptions of the immigrant experience and its effects on five socialization settings (neighborhood, school, family, peer group, and significant other), and each one's relationship to violent behavior. The results led us to believe the young people's immigration experiences had been systematically examined. Their personal and social development was influenced by negative socioeconomic conditions, ineffective parental supervision, maladjustment and conflict at school, and experiences of marginalization and xenophobia. All those conditions favored affiliation with violent groups that provided them instrumental (economic and material), expressive, or affective support.

    Mumma, Brian

    Statement of the problem. Science education literature had agreed that an important goal in students' learning is the development of scientific and technological literacy. One effort that teachers have integrated into their practices for addressing this goal has been teaching within the contexts of Internet Science Projects. Greater awareness of teachers' perspectives of their best practices and their beliefs and reasons for these practices in the contexts of Internet Science Projects can improve the quality of science education programs. Methods. A series of pilot interviews was conducted during the 2000--2001 school year to develop the guiding questions for inquiring into teachers' perspectives of their best practices within the contexts of Internet Science Projects. This series of interviews resulted in the understanding of the need to select teachers with experiences with Internet Science Projects and to conduct in-depth phenomenological interviews for learning from their voices. Two teachers were purposefully selected as the participant-informants for this study, one an American elementary teacher from Walker County, Georgia, and one a Russian teacher from St. Petersburg, Russia. The study was conducted from October through December 2001. The data collected for this qualitative study consisted of a series of in-depth phenomenological interviews, classroom observations, and the collection and analysis of various artifacts including teacher journals, student products, and e-mail/bulletin board transcripts. The interview structure was based upon a modification of expanding Seidman's (1998) three interview series into multiple interviews concluded upon the determination of saturation of the topic. The series of interviews were composed of (1) life history focus; (2) the details of the experience of teaching within the contexts of Internet Science Projects; and (3) reflection on the meanings. The data analysis consisted of applying Strauss & Corbin's (1990) open

  18. The effect of playing a science center-based mobile game: Affective outcomes and gender differences

    Science.gov (United States)

    Atwood-Blaine, Dana

    Situated in a hands-on science center, The Great STEM Caper was a collaborative mobile game built on the ARIS platform that was designed to engage 5th-9th grade players in NGSS science and engineering practices while they interacted with various exhibits. Same gender partners sharing one iPad would search for QR codes placed at specific exhibits; scanning a code within the game would launch a challenge for that exhibit. The primary hypothesis was that in- game victories would be equivalent to "mastery experiences" as described by Bandura (1997) and would result in increased science self-efficacy. Gender differences in gameplay behaviors and perceptions were also studied. The study included two groups, one that played the game during their visit and one that explored the science center in the traditional way. The Motivation to Learn Science Questionnaire was administered to participants in both groups both before and after their visit to the science center. Participants wore head-mounted GoPro cameras to record their interactions within the physical and social environment. No differences in affective outcomes were found between the game and comparison groups or between boys and girls in the game group. The MLSQ was unable to measure any significant change in science self-efficacy, interest and enjoyment of science, or overall motivation to learn science in either group. However, girls outperformed boys on every measure of game achievement. Lazzaro's (2004) four types of fun were found to be a good fit for describing the gender differences in game perceptions and behaviors. Girls tended to enjoy hard fun and collaborative people fun while boys enjoyed easy fun and competitive people fun. While boys associated game achievement with enjoyment and victory, girls perceived their game achievement as difficult, rather than enjoyable or victorious.

  19. The influences and experiences of African American undergraduate science majors at predominately White universities

    Blockus, Linda Helen

    The purpose of this study is to describe and explore some of the social and academic experiences of successful African American undergraduate science majors at predominately White universities with the expectation of conceptualizing emerging patterns for future study. The study surveyed 80 upperclass African Americans at 11 public research universities about their perceptions of the influences that affect their educational experiences and career interests in science. The mailed survey included the Persistence/ voluntary Dropout Decision Scale, the Cultural Congruity Scale and the University Environment Scale. A variety of potential influences were considered including family background, career goals, psychosocial development, academic and social connections with the university, faculty relationships, environmental fit, retention factors, validation, participation in mentored research projects and other experiences. The students' sources of influences, opportunities for connection, and cultural values were considered in the context of a research university environment and investigated for emerging themes and direction for future research. Results indicate that performance in coursework appears to be the most salient factor in African American students' experience as science majors. The mean college gpa was 3.01 for students in this study. Challenging content, time demands, study habits and concern with poor grades all serve to discourage students; however, for most of the students in this study, it has not dissuaded them from their educational and career plans. Positive course performance provided encouragement. Science faculty provide less influence than family members, and more students find faculty members discouraging than supportive. Measures of faculty relations were not associated with academic success. No evidence was provided to confirm the disadvantages of being female in a scientific discipline. Students were concerned with lack of minority role models

    2014-12-01

    Over the past decade the Atmospheric Science Data Center (ASDC) at NASA Langley Research Center has archived and distributed a variety of satellite mission data sets. NASA's goal in Earth science is to observe, understand, and model the Earth system to discover how it is changing, to better predict change, and to understand the consequences for life on Earth. The ASDC has collaborated with Science Teams to accommodate emerging science users in the climate and modeling communities. The ASDC has expanded its original role to support operational usage by related Earth Science satellites, support land and ocean assimilations, support of field campaigns, outreach programs, and application projects for agriculture and energy industries to bridge the gap between Earth science research results and the adoption of data and prediction capabilities for reliable and sustained use in Decision Support Systems (DSS). For example; these products are being used by the community performing data assimilations to regulate aerosol mass in global transport models to improve model response and forecast accuracy, to assess the performance of components of a global coupled atmospheric-ocean climate model, improve atmospheric motion vector (winds) impact on numerical weather prediction models, and to provide internet-based access to parameters specifically tailored to assist in the design of solar and wind powered renewable energy systems. These more focused applications often require Near Real-Time (NRT) products. Generating NRT products pose their own unique set challenges for the ASDC and the Science Teams. Examples of ASDC NRT products and challenges will be discussed.

  6. African American perspectives: A qualitative study of an informal science enrichment program

    Science.gov (United States)

    Simpson, Jamila Rashida

    The purposes of this study were to determine what program characteristics African American parents consider when they enroll their children into an informal science education enrichment program, the parents' evaluation of a program called Jordan Academy in which they enrolled their children, and the alignment of the parents' perspectives with Black Cultural Ethos (BCE). BCE refers to nine dimensions posited by Wade Boykin, a psychologist, as comprising African American culture. Participants were parents of students that attended Jordan Academy, an informal science enrichment program designed for third through sixth grade students from underserved populations. Qualitative methodologies were utilized to perform a thorough assessment of parents' perspectives. Data sources included classroom observations, student surveys, academy curriculum, photos and video-taped class sessions. Data included teachers and parents' responses to semi-structured, audio recorded interviews and students' written responses to open-ended items on the program's evaluation instrument. The data were analyzed for themes and the findings compared to Black Cultural Ethos. Findings revealed that the participants believed that informal science education offered their children opportunities not realized in the formal school setting - a means of impacting their children holistically. The parents expressed the academic, cultural, and personal development of their children in their characterizations of the ideal informal science education experience and in their evaluations of Jordan Academy. Overall, the parents' views emphasized the BCE values of harmony, affect, verve, movement, orality and communalism. The study has important implications for practices within and research on informal science education.

    In the Western tradition, words and vocabulary encapsulate much of how knowledge enters the public discourse, and is passed from one generation to the next. Much of Native American knowledge is passed along in an oral tradition. Chants and ceremonies contain context and long-baseline data on the environment (geology, climate, and astronomy) that may even surpasses the lifespan of a single individual. For Native American students and researchers, the concept of ‘modern research and science education’ may be wrapped up into the conundrum of assimilation and loss of cultural identification and traditional way of life. That conundrum is also associated with the lack of language and vocabulary with which to discuss 'modern research.' Native Americans emphasize the need to know themselves and their own culture when teaching their students. Many Native American communities recognize that the retention of their language - and need to make the language relevant to the technological age we live in, represents one of their largest and most urgent challenges. One strategy for making science education relevant to Native American learners is identifying appropriate terms that cross the cultural divide. More than just words and vocabulary, the thought processes and word/concept relationships can be quite different in the native cultures. The U.S. Rosetta Project has worked to identify words associated with Western 'STEM' concepts in three Native American communities: Navajo, Hawaiian, and Ojibwe. The U.S. Rosetta Project is NASA’s contribution to the International Rosetta Mission. The Rosetta stone, inspiration for the mission’s name, is expected to provide the keys to the primordial solar system the way the original Rosetta Stone provided a key to ancient language. Steps taken so far include identification and presentation of online astronomy, geology, and physical science vocabulary terms in the native language, identification of teachers and classrooms - often in

  18. Examination of factors which may contribute to the underrepresentation of African American teachers certified in science

    Science.gov (United States)

    Davis, Rita C. F.

    Throughout this country the student population is becoming increasingly diverse, yet the teacher population does not reflect this diversity. This lack of diversity in the teacher population deprives students of color from having role models of the same race/ethnicity who look like them and who might have experiences which are similar to theirs (Epstein, 2005; Nettles & Perna, 1997). Having role models from their own race in the classroom could have a positive impact on students' attitudes about science (Perine, 2003), and facilitate their learning of the subject matter, and give students an incentive to do well in school (Vegas, Murnane, & Willett, 2001). In 2000, a national survey study of math and science teachers was conducted (Horizon Research, 2001). The majority of biology (90%), chemistry (93%), and physics (94%) teachers who participated in the study were White. Findings of the study revealed that only 55% to 60% of these teachers considered themselves well prepared to effectively teach a culturally diverse student population (Banilower, 2002; Smith, 2002; Wood, 2002). The majority of the teacher pool, which is White, prefer not to teach in urban communities as they have a preference for teaching jobs in the nonurban communities that are similar to those in which they were raised (Boyd, Lankford, Loeb, & Wyckoff, 2005; Epstein, 2005). The purpose of this quantitative study was to examine factors that may contribute to the underrepresentation of African American teachers certified in science. More specifically, it was decided to examine the high school experiences of in-service teachers. Study participants were teachers and other certificated faculty in two school districts located in the southern portion of the United States. Findings of the study revealed a statistically significant relationship between a teacher's decision to become certified in science and the following high school experiences: teachers and guidance counselors encouraging students to

Worldwide chaos and strife are easily explained as part of the Grimm universe (Grimmverse through Wesen (humanoid creatures who share characteristics with animals such as appearance and behavior, leading to a more united view of humanity and equality of human experience. Evil is often more scientifically explained, and what may appear random within our reality becomes part of a pattern in Grimm.

    Kolo, Yovonda Ingram

    African American women are underrepresented in science, technology, engineering, and mathematics (STEM) fields throughout the United States. As the need for STEM professionals in the United States increases, it is important to ensure that African American women are among those professionals making valuable contributions to society. The purpose of this phenomenological study was to describe the experiences of African American young women in relation to STEM education. The research question for this study examined how experiences with STEM in K-10 education influenced African American young women's academic choices in their final years in high school. The theory of multicontextuality was used to provide the conceptual framework. The primary data source was interviews. The sample was composed of 11 African American young women in their junior or senior year in high school. Data were analyzed through the process of open coding, categorizing, and identifying emerging themes. Ten themes emerged from the answers to research questions. The themes were (a) high teacher expectations, (b) participation in extra-curricular activities, (c) engagement in group-work, (d) learning from lectures, (e) strong parental involvement, (f) helping others, (g) self-efficacy, (h) gender empowerment, (i) race empowerment, and (j) strategic recruitment practices. This study may lead to positive social change by adding to the understanding of the experiences of African American young women in STEM. By doing so, these findings might motivate other African American young women to pursue advanced STEM classes. These findings may also provide guidance to parents and educators to help increase the number of African American women in STEM.

    2015-11-01

    Research reports presented at the American Transplant Congress 2015 provided an array of basic science findings of relevance to the transplant community. Among key themes is the concept that ischemia-reperfusion injury and early posttransplantation inflammation is linked to adaptive alloimmunity and transplant injury. Molecular and cellular mechanisms contributing to these interactions were highlighted. The relevance of understanding how blocking costimulation, including CD40/CD154 interactions, affects various aspects of the alloimmune response was enhanced by the description of preclinical studies demonstrating efficacy of a unique, blocking anti-CD40 monoclonal antibody that could potentially be used in humans. The identification of mechanisms underlying interactions among T cell subsets and B cells, including follicular helper T cells, regulatory T cells, effector B cells, and regulatory B cells, provides multiple previously unrecognized targets for future therapeutic interventions. Additional reports of interest include novel insights into effects of the gut microbiome on graft survival and the ability to differentiate insulin-secreting, islet-like cells from induced pluripotent stem cells. Overall, the reported basic science findings from American Transplant Congress 2015 add to the fundamental understanding of innate and adaptive alloimmunity and provide novel and testable hypotheses that have the potential to be translated into improved clinical care of transplant patients. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Informal science education and especially science and technology centers can play an important role in efforts to raise public awareness of particle physics in particular and of basic research in general. Science Centers are a natural avenue for particle physicists to use to communicate with and gain support from the general public.

  5. Changing Images of the Inclined Plane: A Case Study of a Revolution in American Science Education

    Science.gov (United States)

    Turner, Steven C.

    2012-02-01

    Between 1880 and 1920 the way science was taught in American High Schools changed dramatically. The old "lecture/demonstration" method, where information was presented to essentially passive students, was replaced by the "laboratory" method, where students performed their own experiments in specially constructed student laboratories. National leadership in education was generally weak during this period, and the new method required significant investments by the schools, but within a few decades American science education was rapidly and completely transformed. Previous studies of this fundamental change have concentrated on the activities of organizations like the NEA, the Bureau of Education and a few major universities, but the way in which these groups were able to effect actual changes in classroom practice is not completely clear. This article attempts to broaden the existing narrative by integrating the rich and largely ignored material culture of science education—such things as textbooks, lab manuals, student notebooks, science teaching instruments and scientific instrument catalogs. Surprisingly, much of this story can be seen in changes to the depiction of a single, venerable and otherwise unremarkable teaching instrument: the inclined plane.

  6. Attitudes toward Science (ATS): An Examination of Scientists' and Native Americans' Cultural Values and ATS and Their Effect on Action Priorities

    Science.gov (United States)

    Murry, Adam T.

    Science has been identified as a crucial element in the competitiveness and sustainability of America in the global economy. American citizens, especially minority populations, however, are not pursuing science education or careers. Past research has implicated ‘attitudes toward science’ as an important factor in the public’s participation in science. I applied Ajzen’s (1991) Theory of Planned Behavior to attitudes toward science to predict science-related sustainability-action intentions and evaluated whether scientists and Native Americans differed in their general attitudes toward science, cultural values, and specific beliefs about science. Analyses revealed that positive attitude toward science and the cultural value of individualism predicted intentions to engage with science-related sustainability actions. Unexpectedly, scientists and Native Americans did not differ in their cultural values or positive attitude toward science. However, Natives Americans held significantly more negative attitude toward science than scientists. Implications for science education and attitudes towards science theory and application are discussed.

The organizational framework and activities of the Center have changed and adapted over the years in response to shifts in the scientific issues and challenges facing the U.S. Department of the Interior and with the development of new strategies to meet these challenges. Thus, the history of the Center has been dynamic.

  9. Science Majors and Degrees among Asian-American Students: Influences of Race and Sex in "model Minority" Experiences

    Science.gov (United States)

    Meng, Yu; Hanson, Sandra L.

    Both race and sex continue to be factors that stratify entry into science education and occupations in the United States. Asian-Americans (men and women) have experienced considerable success in the sciences and have earned the label of "model minority." The complexities and patterns involved in this success remain elusive. We use several concepts coming out of the status attainment framework and a multicultural gender perspective to explore the way in which race and sex come together to influence choices of science major and degree. Our sample consists of Asian-American and white students in the National Educational Longitudinal Study. Findings suggest that being male and being Asian-American are both associated with higher chances of pursuing majors and degrees in science. The male advantage is greater than the Asian-American advantage. Findings also suggest that race and sex interact in the science decision. For example, race differences (with an Asian-American advantage) in choice of science major are significant for women but not men. Sex differences (with a male advantage) in choice of science major are significant in the white, but not the Asian-American sample. A different set of race and sex patterns is revealed in the science degree models. Processes associated with family socioeconomic status and student characteristics help to explain race and sex patterns. Findings suggest that when Asian-American youths have closer ties to the Asian culture, they are more likely to choose science majors and degrees. Implications for policy, practice, and research in science education are discussed.

    2003-10-01

    This interpretivist study focused on the professional development of three African American science teachers from a small rural school district, Carver School District (pseudonym), in the southeastern United States. Stories teachers shared of their experiences in teaching and learning science and in their professional development were analyzed using a feminist poststructural analysis of power, knowledge/meaning, language, and difference. For science teaching, power was viewed as a form of ownership or possession and also as effect and processes that impact teaching, learning, and professional development. Teachers through instructional practices exerted a certain amount of power in their classrooms. Teaching practices heavily influenced student learning in science classrooms. For teacher professional development, power was viewed as effecting relationships between administration, peers, and students as a shifting force within different social contexts. Science teachers were perceived as objects of the system and as active social agents who in particular relations of power acted in their best interests as they developed as science teachers. Teachers negotiated for themselves certain power relations to do as they wished for teaching science and for participating in teacher professional development activities. Power was an inherent and critically important aspect in understanding what science teachers do in their classrooms, in teaching and learning science, and in developing as science teachers. Knowledge was closely tied to relations of power in that teachers acquired knowledge about themselves, their teaching of science, and their students from their past experiences and professional development activities. Through language, interactions between teachers and students enabled or disabled access to the culture of power via instructional practices. Language was implicated in teacher professional development as a powerful force for advancing or hindering teachers

    Racism constitutes a significant risk to the healthy development of African American youth. Fortunately, however, not all youth who experience racism evidence negative developmental outcomes. In this chapter, we examine person-centered analysis (PCA)-a quantitative technique that investigates how variables combine across individuals-as a useful tool for elucidating racial and ethnic protective processes that mitigate the negative impact of racism. We review recent studies employing PCA in examinations of racial identity, racial socialization, and other race-related experiences, as well as how these constructs correlate with and impact African American youth development. We also consider challenges and limitations of PCA and conclude with a discussion of future research and how PCA might be used to promote equity and justice for African American and other racial and ethnic minority youth who experience racism. © 2016 Elsevier Inc.

  14. Listening to their voices: Exploring mathematics-science identity development of African American males in an urban school community

    Science.gov (United States)

    Wilson, Kimi Leemar

    National data continues to show an underrepresentation of African American males pursuing science, technology, engineering and mathematics (STEM) majors, careers and professions in the United States. Whites and Asian Americans are continuously positioned as the face of STEM education and participation. And while research has provided ways to support mathematics and science learning for African American males, there still remains a gap in understanding how their formed mathematics-science identities in K-12 public schooling influences STEM participation. The research undertaken in this study explores this gap, and uses an integrative identity framework to understand mathematics-science identity development which goes beyond personal identity, and explores the relational, collective and material components of identity. Specifically, this research seeks to answer the following research questions: What are the shared lived experiences that exist between a group of African American male students developing a mathematics-science identity, and how these shared lived experiences shape their mathematics-science identity development? Therefore, by analyzing African American males lived experiences employing an integrative identity framework fosters a greater understanding of how mathematics-science identity is formed in K-12 public schools, which impacts STEM education and participation. The high school aged youth featured in this study consist of four African American males, who live in a moderate size city in California. Data for this study consists of observations, phenomenological interviews, and policy document analysis that took place over six months. Data has been analyzed to describe and interpret the young men's mathematics and science experiences, as revealed in their K-12 public school education. This inquiry sought to make meaning of how African American males experience mathematics and science teaching and learning within K-12 public schooling and how these

  15. Young African American children constructing identities in an urban integrated science-literacy classroom

    Science.gov (United States)

    Kane, Justine M.

    This is a qualitative study of identities constructed and enacted by four 3rd-grade African American children (two girls and two boys) in an urban classroom that engaged in a year-long, integrated science-literacy project. Juxtaposing narrative and discursive identity lenses, coupled with race and gender perspectives, I examined the ways in which the four children saw and performed themselves as students and as science students in their classroom. Interview data were used for the narrative analysis and classroom Discourse and artifacts were used for the discursive analysis. A constructivist grounded theory framework was adopted for both analyses. The findings highlight the diversity and richness of perspectives and forms of engagement these young children shared and enacted, and help us see African American children as knowers, doers, and talkers of science individually and collectively. In their stories about themselves, all the children identified themselves as smart but they associated with smartness different characteristics and practices depending on their strengths and preferences. Drawing on the children's social, cultural, and ethnolinguistic resources, the dialogic and multimodal learning spaces facilitated by their teacher allowed the children to explore, negotiate, question, and learn science ideas. The children in this study brought their understandings and ways of being into the "lived-in" spaces co-created with classmates and teacher and influenced how these spaces were created. At the same time, each child's ways of being and understandings were shaped by the words, actions, behaviors, and feelings of peers and teacher. Moreover, as these four children engaged with science-literacy activities, they came to see themselves as competent, creative, active participants in science learning. Although their stories of "studenting" seemed dominated by following rules and being well-behaved, their stories of "sciencing" were filled with exploration, ingenuity

    NASA's Science Mission Directorate aims to stimulate public interest in Earth system science and to encourage young scholars to consider careers in science, technology, engineering and mathematics. NASA's Atmospheric Science Data Center (ASDC) at Langley Research Center houses over 700 data sets related to Earth's radiation budget, clouds, aerosols and tropospheric chemistry that are being produced to increase academic understanding of the natural and anthropogenic perturbations that influence global climate change. However, barriers still exist in the use of these actual satellite observations by educators in the classroom to supplement the educational process. Thus, NASA is sponsoring the "Mentoring and inquirY using NASA Data on Atmospheric and earth science for Teachers and Amateurs" (MY NASA DATA) project to systematically support educational activities by reducing the ASDC data holdings to `microsets' that can be easily accessible and explored by the K-16 educators and students. The microsets are available via Web site (http://mynasadata.larc.nasa.gov) with associated lesson plans, computer tools, data information pages, and a science glossary. A MY NASA DATA Live Access Server (LAS) has been populated with ASDC data such that users can create custom microsets online for desired time series, parameters and geographical regions. The LAS interface is suitable for novice to advanced users, teachers or students. The microsets may be visual representations of data or text output for spreadsheet analysis. Currently, over 148 parameters from the Clouds and the Earth's Radiant Energy System (CERES), Multi-angle Imaging SpectroRadiometer (MISR), Surface Radiation Budget (SRB), Tropospheric Ozone Residual (TOR) and the International Satellite Cloud Climatology Project (ISCCP) are available and provide important information on clouds, fluxes and cycles in the Earth system. Additionally, a MY NASA DATA OPeNDAP server has been established to facilitate file transfer of

    2013-01-01

    The Department of the Interior (DOI) recognizes and embraces the unprecedented challenges of maintaining our Nation’s rich natural and cultural resources in the 21st century. The magnitude of these challenges demands that the conservation community work together to develop integrated adaptation and mitigation strategies that collectively address the impacts of climate change and other landscape-scale stressors. On September 14, 2009, DOI Secretary Ken Salazar signed Secretarial Order 3289 (amended February 22, 2010) entitled, “Addressing the Impacts of Climate Change on America’s Water, Land, and Other Natural and Cultural Resources.” The Order establishes the foundation for two partner-based conservation science entities to address these unprecedented challenges: Climate Science Centers (CSCs and Landscape Conservation Cooperatives (LCCs). CSCs and LCCs are the Department-wide approach for applying scientific tools to increase understanding of climate change and to coordinate an effective response to its impacts on tribes and the land, water, ocean, fish and wildlife, and cultural-heritage resources that DOI manages. Eight CSCs have been established and are managed through the U.S. Geological Survey (USGS) National Climate Change and Wildlife Science Center (NCCWSC); each CSC works in close collaboration with their neighboring CSCs, as well as those across the Nation, to ensure the best and most efficient science is produced. The South Central CSC was established in 2012 through a cooperative agreement with the University of Oklahoma, Texas Tech University, Louisiana State University, the Chickasaw Nation, the Choctaw Nation of Oklahoma, Oklahoma State University, and NOAA’s Geophysical Fluid Dynamics Lab; hereafter termed the ”Consortium” of the South Central CSC. The Consortium has a broad expertise in the physical, biological, natural, and social sciences to address impacts of climate change on land, water, fish and wildlife, ocean, coastal, and

    2001-05-01

    For more than ten years, the College of Oceanic and Atmospheric Sciences at Oregon State University has carried out the Native Americans in Marine and Space Sciences (NAMSS) Program. Its long-term goal is to increase the number of American Indian and Native Alaskan undergraduates in science who complete degrees, continue to graduate school and enter the professional scientific work force. Ninety-eight percent of NAMSS students have earned BS degrees and almost forty percent have continued in graduate school. These are impressive results considering the high national drop-out rate for Native American studentsaround 70% according to the Chronicle of Higher Education (26 May 1993, page A29). Most often, Native students wishing to earn degrees in science find few programs that fit with their traditional sense of place and community. Most programs are narrowly focused and do not support or nurture Native views of interrelationship of all things. While Western science's recent ecological systems thinking approach more closely resembles the traditional Native view, Traditional Ecological Knowledge is often perceived as anecdotal or storytelling and not real science. This is a problem for Native students who are strongly underrepresented in the U.S. scientific community as a whole and nearly absent from the marine sciences. Undergraduates from this group are without scientific career models or mentors from their ethnic group and experience difficulty establishing contacts with majority scientists. They have limited access to opportunities to explore career possibilities in the sciences through research participation. Once on campus they have difficulty establishing a sense of belonging in the University community and do not have an organized way to enter into the scientific activities that initially attracted them. Representation of Native Americans in the ranks of U.S. scientists will not be increased without special efforts to retain them as undergraduates and to recruit

    Fouquier, Katherine Ferrell

    2013-01-01

    This article reviews the current state of knowledge of the theory of maternal role attainment (MRA) and its relevance in describing African American motherhood. EBSCOhost Research Databases that included PubMed, CINAHL plus, MEDLINE, PsycINFO, SCOPUS, and Web of Science were searched for journal articles that examined maternal identity and MRA. Keyword searches included maternal identity, maternal role attainment, becoming a mother, prenatal attachment, maternal-fetal attachment, and maternal-infant attachment. Inclusion criteria for this review were published journal articles of studies conducted in the United States, with a clear delineation of the theoretical framework of MRA. Journal articles that measured MRA among women with depression or medically fragile infants were excluded. Two hundred and twelve studies were reviewed; 25 studies, published between 1975 and 2007, met the inclusion criteria. Nine articles described the theory of MRA, 11 articles measured variables thought to influence MRA, and 6 articles described maternal-fetal attachment, a construct of MRA. Studies were reviewed, categorized, and analyzed to determine current knowledge of how the theory of MRA describes African American motherhood. Categories included studies describing the theoretical framework of maternal identity and MRA, studies measuring key variables thought to impact MRA, and studies measuring maternal-fetal attachment and maternal-infant attachment. The studies were limited by homogenous samples of upper-middle-class white women and low-income, single, African American adolescents. Study results of MRA cannot be generalized to African American women. Further research is essential to identify attributes influencing MRA, specifically among larger samples of African American women with demographics similar to that of the white populations that have been included in studies thus far. © 2013 by the American College of Nurse-Midwives.

    As part of the Basic Science Survey Series (BSSS) for Dentistry, members of the American Dental Education Association (ADEA) Anatomical Sciences Section surveyed faculty members teaching embryology and histology courses at North American dental schools. The survey was designed to assess, among other things, curriculum content, utilization of laboratories, use of computer-assisted instruction (CAI), and recent curricular changes. Responses were received from fifty-nine (88.1 percent) of the sixty-seven U.S. and Canadian dental schools. Findings suggest the following: 1) a trend toward combining courses is evident, though the integration was predominantly discipline-based; 2) embryology is rarely taught as a stand-alone course, as content is often covered in gross anatomy, oral histology, and/or in an integrated curriculum; 3) the number of contact hours in histology is decreasing; 4) a trend toward reduction in formal laboratory sessions, particularly in embryology, is ongoing; and 5) use of CAI tools, including virtual microscopy, in both embryology and histology has increased. Additionally, embryology and histology content topic emphasis is identified within this study. Data, derived from this study, may be useful to new instructors, curriculum and test construction committees, and colleagues in the anatomical sciences, especially when determining a foundational knowledge base.

    Background: Since Tehran University of Medical Sciences (TUMS) has the oldest and highest number of research centers among all Iranian medical universities, this study was conducted to evaluate scientific output of research centers affiliated to Tehran University of Medical Sciences (TUMS) using scientometric indices and the affecting factors. Moreover, a number of scientometric indicators were introduced. Methods: This cross-sectional study was performed to evaluate a 5-year scientific performance of research centers of TUMS. Data were collected through questionnaires, annual evaluation reports of the Ministry of Health, and also from Scopus database. We used appropriate measures of central tendency and variation for descriptive analyses. Moreover, uni-and multi-variable linear regression were used to evaluate the effect of independent factors on the scientific output of the centers. Results: The medians of the numbers of papers and books during a 5-year period were 150.5 and 2.5 respectively. The median of the "articles per researcher" was 19.1. Based on multiple linear regression, younger age centers (p=0.001), having a separate budget line (p=0.016), and number of research personnel (p<0.001) had a direct significant correlation with the number of articles while real properties had a reverse significant correlation with it (p=0.004). Conclusion: The results can help policy makers and research managers to allocate sufficient resources to improve current situation of the centers. Newly adopted and effective scientometric indices are is suggested to be used to evaluate scientific outputs and functions of these centers. PMID:26157724

  5. Expecting the Unexpected: a Comparative Study of African-American Women's Experiences in Science during the High School Years

    Hanson, Sandra L.; Johnson, Elizabeth Palmer

    Data from the National Educational Longitudinal Study (NELS) for the years 1988 to 1992 are used to explore the science experiences of young African-American women during the high school years. The comparison groups we use in trying to understand these experiences involve White women (for a race contrast) and African-American men (for a gender contrast). Within the context of a critical feminist perspective, it is argued that gender is constructed in a different way in White and African-American communities. Instead of expecting a disadvantage for young African-American women because of their gender and minority statuses, it is suggested that unique gender ideologies and work-family arrangements in the African-American community give these young women the resources and agency that allow them to compete with their White female counterparts and their African-American male counterparts in the science domain. Results from our analyses of the NELS data confirm these expectations. We find that on a majority of science measures, African-American women do as well as - and sometimes better than - White women and African-American men. For example, there are no differences between African-American women and men on attitudes toward science. And when compared with White women, African-American women tend to have more positive attitudes. When disadvantages appear for these young African-American women, they are more likely to be race effects then gender effects. The minimal gender effects in the science experiences of young African-Americans is in contrast to the more frequent male advantage in the White sample. A careful examination of family and individual resources shows that African-American families compensate for disadvantages on some resources (e.g., family socioeconomic status) by providing young women with an excess of other resources (e.g., unique gender ideologies, work expectations, and maternal expectations and involvement). And, unlike White parents, they sometimes

    Performance assessment in congenital heart surgery is challenging due to the wide heterogeneity of disease. We describe current case mix across centers, evaluate methodology inclusive of all cardiac operations versus the more homogeneous subset of Society of Thoracic Surgeons benchmark operations, and describe implications regarding performance assessment. Centers (n = 119) participating in the Society of Thoracic Surgeons Congenital Heart Surgery Database (2010 through 2014) were included. Index operation type and frequency across centers were described. Center performance (risk-adjusted operative mortality) was evaluated and classified when including the benchmark versus all eligible operations. Overall, 207 types of operations were performed during the study period (112,140 total cases). Few operations were performed across all centers; only 25% were performed at least once by 75% or more of centers. There was 7.9-fold variation across centers in the proportion of total cases comprising high-complexity cases (STAT 5). In contrast, the benchmark operations made up 36% of cases, and all but 2 were performed by at least 90% of centers. When evaluating performance based on benchmark versus all operations, 15% of centers changed performance classification; 85% remained unchanged. Benchmark versus all operation methodology was associated with lower power, with 35% versus 78% of centers meeting sample size thresholds. There is wide variation in congenital heart surgery case mix across centers. Metrics based on benchmark versus all operations are associated with strengths (less heterogeneity) and weaknesses (lower power), and lead to differing performance classification for some centers. These findings have implications for ongoing efforts to optimize performance assessment, including choice of target population and appropriate interpretation of reported metrics.

    Climate science, already a highly interdisciplinary field, is rapidly evolving, and natural resource managers are increasingly involved in policymaking and adaptation decisions to address climate change that need to be informed by state-of-the-art climate science. Consequently, there is a strong demand for unique organizations that engender collaboration and cooperation between government, non-profit, academic and for-profit sectors that are addressing issues relating to natural resources management and climate adaptation and resilience. These organizations are often referred to as boundary organizations. The Northwest Climate Science Center (NW CSC) and the North Pacific Landscape Conservation Cooperative (NP LCC) are two such boundary organizations operating in different contexts. Together, the NW CSC and the NP LCC fulfill the need for sites of co-production between researchers and managers working on climate-related issues, and a key component of this work is a monthly climate science newsletter that includes recent climate science journal articles, reports, and climate-related events. Our study evaluates the effectiveness of the climate science digest (CSD) through a three-pronged approach: a) in-depth interviews with natural resource managers who use the CSD, b) poll questions distributed to CSD subscribers, and c) quantitative analysis of CSD effectiveness using analytics from MailChimp distribution. We aim to a) map the reach of the CSD across the Northwest and at a national level; b) understand the efficacy of the CSD at communicating climate science to diverse audiences; c) evaluate the usefulness of CSD content for diverse constituencies of subscribers; d) glean transferrable knowledge for future evaluations of boundary management tools; and e) establish a protocol for designing climate science newsletters for other agencies disseminating climate science information. We will present results from all three steps of our evaluation process and describe

    This report documents the standard procedures, policies, and field methods used by the U.S. Geological Survey’s (USGS) Washington Water Science Center staff for activities related to the collection, processing, analysis, storage, and publication of groundwater data. This groundwater quality-assurance plan changes through time to accommodate new methods and requirements developed by the Washington Water Science Center and the USGS Office of Groundwater. The plan is based largely on requirements and guidelines provided by the USGS Office of Groundwater, or the USGS Water Mission Area. Regular updates to this plan represent an integral part of the quality-assurance process. Because numerous policy memoranda have been issued by the Office of Groundwater since the previous groundwater quality assurance plan was written, this report is a substantial revision of the previous report, supplants it, and contains significant additional policies not covered in the previous report. This updated plan includes information related to the organization and responsibilities of USGS Washington Water Science Center staff, training, safety, project proposal development, project review procedures, data collection activities, data processing activities, report review procedures, and archiving of field data and interpretative information pertaining to groundwater flow models, borehole aquifer tests, and aquifer tests. Important updates from the previous groundwater quality assurance plan include: (1) procedures for documenting and archiving of groundwater flow models; (2) revisions to procedures and policies for the creation of sites in the Groundwater Site Inventory database; (3) adoption of new water-level forms to be used within the USGS Washington Water Science Center; (4) procedures for future creation of borehole geophysics, surface geophysics, and aquifer-test archives; and (5) use of the USGS Multi Optional Network Key Entry System software for entry of routine water-level data

    1998-01-01

    The communication of new scientific knowledge and understanding is an integral component of science research, essential for its continued survival. Like any learning- based activity, science cannot continue without communication between and among peers so that skeptical inquiry and learning can take place. This communication provides necessary organic support to maintain the development of new knowledge and technology. However, communication beyond the peer-community is becoming equally critical for science to survive as an enterprise into the 21st century. Therefore, scientists not only have a 'noble responsibility' to advance and communicate scientific knowledge and understanding to audiences within and beyond the peer-community, but their fulfillment of this responsibility is necessary to maintain the survival of the science enterprise. Despite the critical importance of communication to the viability of science, the skills required to perform effective science communications historically have not been taught as a part of the training of scientist, and the culture of science is often averse to significant communication beyond the peer community. Thus scientists can find themselves ill equipped and uncomfortable with the requirements of their job in the new millennium. At NASA/Marshall Space Flight Center, we have developed and implemented an integrated science communications process, providing an institutional capability to help scientist accurately convey the content and meaning of new scientific knowledge to a wide variety of audiences, adding intrinsic value to the research itself through communication, while still maintaining the integrity of the peer-review process. The process utilizes initial communication through the world-wide web at the site http://science.nasa.gov to strategically leverage other communications vehicles and to reach a wide-variety of audiences. Here we present and discuss the basic design of the science communications process, now in

    Life sciences data collected before, during and after spaceflight are valuable and often irreplaceable. The Johnson Space Center Life is hard to find, and much of the data (e.g. Sciences Data Archive has been designed to provide researchers, engineers, managers and educators interactive access to information about and data from human spaceflight experiments. The archive system consists of a Data Acquisition System, Database Management System, CD-ROM Mastering System and Catalog Information System (CIS). The catalog information system is the heart of the archive. The CIS provides detailed experiment descriptions (both written and as QuickTime movies), hardware descriptions, hardware images, documents, and data. An initial evaluation of the archive at a scientific meeting showed that 88% of those who evaluated the catalog want to use the system when completed. The majority of the evaluators found the archive flexible, satisfying and easy to use. We conclude that the data archive effectively provides key life sciences data to interested users.

  16. Perspectives on learning through research on critical issues-based science center exhibitions

    Pedretti, Erminia G.

    2004-07-01

    Recently, science centers have created issues-based exhibitions as a way of communicating socioscientific subject matter to the public. Research in the last decade has investigated how critical issues-based installations promote more robust views of science, while creating effective learning environments for teaching and learning about science. The focus of this paper is to explore research conducted over a 10-year period that informs our understanding of the nature of learning through these experiences. Two specific exhibitions - Mine Games and A Question of Truth - provide the context for discussing this research. Findings suggest that critical issues-based installations challenge visitors in different ways - intellectually and emotionally. They provide experiences beyond usual phenomenon-based exhibitions and carry the potential to enhance learning by personalizing subject matter, evoking emotion, stimulating dialogue and debate, and promoting reflexivity. Critical issues-based exhibitions serve as excellent environments in which to explore the nature of learning in these nonschool settings.

    Conflicts of interest (COI) in research are an important emerging topic of investigation and are frequently cited as a serious threat to the integrity of human participant research. To study financial conflicts of interest (FCOI) policies for individual investigators working in Canadian academic health centers. Survey instrument containing 61 items related to FCOI. All Canadian academic health science centers (universities with faculties of medicine, faculties of medicine and teaching hospitals) were requested to provide their three primary FCOI policies. Number of all centers and teaching hospitals with policies addressing each of the 61 items related to FCOI. Only one item was addressed by all 74 centers. Thirteen items were present in fewer than 25% of centers. Fewer than one-quarter of hospitals required researchers to disclose FCOI to research participants. The role of research ethics boards (REBs) in hospitals was marginal. Asking centers to identify only three policies may not have inclusively identified all FCOI policies in use. Additionally, policies at other levels might apply. For instance, all institutions receiving federal grant money must comply with the Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans. Canadian centers within the same level (for instance, teaching hospitals) differ significantly in the areas that their policies address and these policies differ widely in their coverage. Presently, no single policy in any Canadian center informs researchers about the broad range of individual FCOI issues. Canadian investigators need to understand the environment surrounding FCOI, be able to access and follow the relevant policies and be confident that they can avoid entering into a FCOI.

  2. Fear of failure: why american science is not winning the war on cancer.

    How to maximize creativity in biological science is a topic rarely discussed and yet critical to success in improving health. I believe that the needed approaches are not simply to flog individuals to try harder but to build systems and infrastructures that enhance creative effort. Lateral thinking can and should be taught. My hope for the future is that every graduate science curriculum will have a course in innovation. Institutions must provide time, space, and individual credit to the long and slow process of creative output. Highly multidisciplinary science should be supported, some of which may require seed or infrastructure support. Funders can separate idea generation from implementation. Scientists can minimize costs of failure by piloting and modeling ideas through incremental research, if supported by funders. But perhaps the very first step is to initiate a vibrant discussion of what we can do to enhance creativity in American biological science-it is time to stop complaining and to start winning the war on cancer.

    We examined the prevalence and extent of informed decision-making (IDM) and patient-centered decision-making (PCDM) in primary care visits of African Americans with depression. We performed a cross-sectional analysis of audiotaped clinical encounters and post-visit surveys of 76 patients and their clinicians. We used RIAS to characterize patient-centeredness of visit dialogue. IDM entailed discussion of 3 components: the nature of the decision, alternatives, and pros/cons. PCDM entailed discussion of: lifestyle/coping strategies, knowledge/beliefs, or treatment concerns. We examined the association of IDM and PCDM with visit duration, overall patient-centeredness, and patient/clinician interpersonal ratings. Approximately one-quarter of medication and counseling decisions included essential IDM elements and 40% included at least one PCDM element. In high patient-centered visits, IDM was associated with patients feeling respected in counseling and liking clinicians in medication decisions. IDM was not related to clinician ratings. In low patient-centered visits, PCDM in counseling decisions was positively associated with patients feeling respected and clinicians respecting patients. The associations between IDM and PCDM with interpersonal ratings was moderated by overall patient-centeredness of the visit, which may be indicative of broader cross-cultural communication issues. Strengthening partnerships between depressed African Americans and their clinicians may improve patient-engaged decision-making. Copyright © 2017 Elsevier B.V. All rights reserved.

  4. Senator Fred Harris's National Social Science Foundation proposal: Reconsidering federal science policy, natural science-social science relations, and American liberalism during the 1960s.

    2012-03-01

    During the 1960s, a growing contingent of left-leaning voices claimed that the social sciences suffered mistreatment and undue constraints within the natural science-dominated federal science establishment. According to these critics, the entrenched scientific pecking order in Washington had an unreasonable commitment to the unity of the sciences, which reinforced unacceptable inequalities between the social and the natural sciences. The most important political figure who advanced this critique, together with a substantial legislative proposal for reform, was the Oklahoma Democratic Senator Fred Harris. Yet histories of science and social science have told us surprisingly little about Harris. Moreover, existing accounts of his effort to create a National Social Science Foundation have misunderstood crucial features of this story. This essay argues that Harris's NSSF proposal developed into a robust, historically unique, and increasingly critical liberal challenge to the post-World War II federal science establishment's treatment of the social sciences as "second-class citizens."

    The Great American Eclipse of 2017 provided an excellent opportunity for heliophysics research on the solar corona and dynamics that encompassed a large number of research groups and projects, including projects flown in the air and in space. Two NASA WB-57F Canberra high altitude research aircraft were launched from NASA's Johnson Space Center, Ellington Field into the eclipse path. At an altitude of 50,000ft, and outfitted with visible and near-infrared cameras, these aircraft provided increased duration of observations during eclipse totality, and much sharper images than possible on the ground. Although the primary mission goal was to study heliophysics, planetary science was also conducted to observe the planet Mercury and to search for Vulcanoids. Mercury is extremely challenging to study from Earth. The 2017 eclipse provided a rare opportunity to observe Mercury under ideal astronomical conditions. Only a handful of near-IR thermal images of Mercury exist, but IR images provide critical surface property (composition, albedo, porosity) information, essential to interpreting lower resolution IR spectra. Critically, no thermal image of Mercury currently exists. By observing the nightside surface during the 2017 Great American Eclipse, we aimed to measure the diurnal temperature as a function of local time (longitude) and attempted to deduce the surface thermal inertia integrated down to a few-cm depth below the surface. Vulcanoids are a hypothesized family of asteroids left over from the formation of the solar system, in the dynamically stable orbits between the Sun and Mercury at 15-45 Rs (4-12° solar elongation). Close proximity to the Sun, plus their small theoretical sizes, make Vulcanoid searches rare and difficult. The 2017 eclipse was a rare opportunity to search for Vulcanoids. If discovered these unique, highly refractory and primordial bodies would have a significant impact on our understanding of solar system formation. Only a handful of deep

    The presence of nutrition as an independent matter in the educational programs of the Spanish Faculties of Medicine has been scanty until the end of the XXth century. We have witnessed an important development of the specific opportunities for the nutritional sciences in terms of quality and quantity in the XXIst century. Only one Ibero Latin American journal, Archivos Latinoamericanos de Nutrición (ALAN, ISSN 0004-0622), was present in the Journal Citation Reports, Science Edition among the 51 journals under the heading of Nutrition & Dietetics. Three more ibero latin American journals have been incorporated to JCR in the XXIst century, Nutrición Hospitalaria (Nutr Hosp, ISSN 0212-1611) in 2006, Revista de Nutricao (Rev Nutr, ISSN 1415-5273) and Revista Española de Nutrición Comunitaria (Rev Esp Nutr Comunit, ISSN 1135-3074) in 2007. The four journals are having a growing importance in other electronic platforms, rendering an important service to the scientific society, not only in their environment, but also in the rest of the world. Although English language dominates scientific communications, the critical mass of already existing journals in Spanish and the area of influence of this language is a good stimulus for continuing its utilization.

    The Woods Hole Science Center of the U.S. Geological Survey (USGS) has been an active member of the Woods Hole research community, Woods Hole, Massachusetts, for over 40 years. In that time there have been many projects that involved the collection of sediment samples conducted by USGS scientists and technicians for the research and study of seabed environments and processes. These samples were collected at sea or near shore and then brought back to the Woods Hole Science Center (WHSC) for analysis. While at the center, samples are stored in ambient temperature, refrigerated and freezing conditions ranging from +2º Celsius to -18º Celsius, depending on the best mode of preparation for the study being conducted or the duration of storage planned for the samples. Recently, storage methods and available storage space have become a major concern at the WHSC. The core and sediment archive program described herein has been initiated to set standards for the management, methods, and duration of sample storage. A need has arisen to maintain organizational consistency and define storage protocol. This handbook serves as a reference and guide to all parties interested in using and accessing the WHSC's sample archive and also defines all the steps necessary to construct and maintain an organized collection of geological samples. It answers many questions as to the way in which the archive functions.

    As world demand for energy rapidly expands, transforming the way energy is collected, stored, and used has become a defining challenge of the 21st century. At its heart, this challenge is a scientific one, inspiring the U.S. Department of Energy’s (DOE) Office of Basic Energy Sciences (BES) to establish the Energy Frontier Research Center (EFRC) program in 2009. The EFRCs represent a unique approach, bringing together creative, multidisciplinary scientific teams to perform energy-relevant basic research with a complexity beyond the scope of single-investigator projects. These centers take full advantage of powerful new tools for characterizing, understanding, modeling, and manipulating matter from atomic to macroscopic length scales. They also train the next-generation scientific workforce by attracting talented students and postdoctoral researchers interested in energy science. The EFRCs have collectively demonstrated the potential to substantially advance the scientific understanding underpinning transformational energy technologies. Both a BES Committee of Visitors and a Secretary of Energy Advisory Board Task Force have found the EFRC program to be highly successful in meeting its goals. The scientific output from the EFRCs is impressive, and many centers have reported that their results are already impacting both technology research and industry. This report on the EFRC program includes selected highlights from the initial 46 EFRCs and the current 36 EFRCs.

    The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), in addition to serving the Earth Science community as one of the major Distributed Active Archive Centers (DAACs), provides much more than just data. Among the value-added services available to general users are subsetting data spatially and/or by parameter, online analysis (to avoid downloading unnecessary all the data), and assistance in obtaining data from other centers. Services available to data producers and high-volume users include consulting on building new products with standard formats and metadata and construction of data management systems. A particularly useful service is data processing at the DISC (i.e., close to the input data) with the users' algorithms. This can take a number of different forms: as a configuration-managed algorithm within the main processing stream; as a stand-alone program next to the on-line data storage; as build-it-yourself code within the Near-Archive Data Mining (NADM) system; or as an on-the-fly analysis with simple algorithms embedded into the web-based tools. Partnerships between the GES DISC and scientists, both producers and users, allow the scientists concentrate on science, while the GES DISC handles the of data management, e.g., formats, integration and data processing. The existing data management infrastructure at the GES DISC supports a wide spectrum of options: from simple data support to sophisticated on-line analysis tools, producing economies of scale and rapid time-to-deploy. At the same time, such partnerships allow the GES DISC to serve the user community more efficiently and to better prioritize on-line holdings. Several examples of successful partnerships are described in the presentation.

  18. An Analysis of Cloud Computing with Amazon Web Services for the Atmospheric Science Data Center

    Science.gov (United States)

    Gleason, J. L.; Little, M. M.

    2013-12-01

    NASA science and engineering efforts rely heavily on compute and data handling systems. The nature of NASA science data is such that it is not restricted to NASA users, instead it is widely shared across a globally distributed user community including scientists, educators, policy decision makers, and the public. Therefore NASA science computing is a candidate use case for cloud computing where compute resources are outsourced to an external vendor. Amazon Web Services (AWS) is a commercial cloud computing service developed to use excess computing capacity at Amazon, and potentially provides an alternative to costly and potentially underutilized dedicated acquisitions whenever NASA scientists or engineers require additional data processing. AWS desires to provide a simplified avenue for NASA scientists and researchers to share large, complex data sets with external partners and the public. AWS has been extensively used by JPL for a wide range of computing needs and was previously tested on a NASA Agency basis during the Nebula testing program. Its ability to support the Langley Science Directorate needs to be evaluated by integrating it with real world operational needs across NASA and the associated maturity that would come with that. The strengths and weaknesses of this architecture and its ability to support general science and engineering applications has been demonstrated during the previous testing. The Langley Office of the Chief Information Officer in partnership with the Atmospheric Sciences Data Center (ASDC) has established a pilot business interface to utilize AWS cloud computing resources on a organization and project level pay per use model. This poster discusses an effort to evaluate the feasibility of the pilot business interface from a project level perspective by specifically using a processing scenario involving the Clouds and Earth's Radiant Energy System (CERES) project.

  19. Classroom Activities: Simple Strategies to Incorporate Student-Centered Activities within Undergraduate Science Lectures.

    Lom, Barbara

    2012-01-01

    The traditional science lecture, where an instructor delivers a carefully crafted monolog to a large audience of students who passively receive the information, has been a popular mode of instruction for centuries. Recent evidence on the science of teaching and learning indicates that learner-centered, active teaching strategies can be more effective learning tools than traditional lectures. Yet most colleges and universities retain lectures as their central instructional method. This article highlights several simple collaborative teaching techniques that can be readily deployed within traditional lecture frameworks to promote active learning. Specifically, this article briefly introduces the techniques of: reader's theatre, think-pair-share, roundtable, jigsaw, in-class quizzes, and minute papers. Each technique is broadly applicable well beyond neuroscience courses and easily modifiable to serve an instructor's specific pedagogical goals. The benefits of each technique are described along with specific examples of how each technique might be deployed within a traditional lecture to create more active learning experiences.

    Full Text Available The present article analyzes the activity “Guided Visit of School Groups” carried out at Astronomical Observatory of the Center for Scientific and Cultural Diffusion (CDCC of University of Sao Paulo (USP with K4 and K5 pupils. The objectives of this research were to identify influences of such activity on learning of astronomical concepts and on pupils’ motivation. The results demonstrate that pupils have difficulties to understand Solar System concepts and the distances involved, on the other hand, the activity motivates the pupils to return with their parents and friends to the Observatory. At last, the success of visits to science centers aiming at the learning of basic concepts and motivation comprises at least three moments: the one that precedes the visit, the visit itself and the return to the classroom.

    Lackett, J.; Ojima, D. S.; McNeeley, S.

    2017-12-01

    As climate change impacts become more apparent in our environment, action is needed to enhance the social-ecological system resilience. Incorporating principles which lead to actionable research and project co-development, when appropriate, will facilitate building linkages between the research and the natural resource management communities. In order to develop strategies to manage for climatic and ecosystem changes, collaborative actions are needed between researchers and resource managers to apply appropriate knowledge of the ecosystem and management environments to enable feasible solutions and management actions to respond to climate change. Our team has been involved in developing and establishing a research and engagement center, the North Central Climate Science Center (NC CSC), for the US Department of Interior, to support the development and translation of pertinent climate science information to natural resource managers in the north central portion of the United States. The NC CSC has implemented a platform to support the Resource for Vulnerability Assessment, Adaptation, and Mitigation Projects (ReVAMP) with research, engagement, and training activities to support resource managers and researchers. These activities are aimed at the co-production of appropriate response strategies to climate change in the region, in particular to drought-related responses. Through this platform we, with other partners in the region, including the Department of Interior and the Department of Agriculture, are bringing various training tools, climate information, and management planning tools to resource managers. The implementation of ReVAMP has led to development of planning efforts which include a more explicit representation of climate change as a driver of drought events in our region. Scenario planning provides a process which integrates management goals with possible outcomes derived from observations and simulations of ecological impacts of climate change. Co

  11. NASA Lunar Sample Education Disk Program - Space Rocks for Classrooms, Museums, Science Centers and Libraries

    2009-12-01

    NASA is eager for students and the public to experience lunar Apollo rocks and regolith soils first hand. Lunar samples embedded in plastic are available for educators to use in their classrooms, museums, science centers, and public libraries for education activities and display. The sample education disks are valuable tools for engaging students in the exploration of the Solar System. Scientific research conducted on the Apollo rocks has revealed the early history of our Earth-Moon system. The rocks help educators make the connections to this ancient history of our planet as well as connections to the basic lunar surface processes - impact and volcanism. With these samples educators in museums, science centers, libraries, and classrooms can help students and the public understand the key questions pursued by missions to Moon. The Office of the Curator at Johnson Space Center is in the process of reorganizing and renewing the Lunar and Meteorite Sample Education Disk Program to increase reach, security and accountability. The new program expands the reach of these exciting extraterrestrial rocks through increased access to training and educator borrowing. One of the expanded opportunities is that trained certified educators from science centers, museums, and libraries may now borrow the extraterrestrial rock samples. Previously the loan program was only open to classroom educators so the expansion will increase the public access to the samples and allow educators to make the critical connections of the rocks to the exciting exploration missions taking place in our solar system. Each Lunar Disk contains three lunar rocks and three regolith soils embedded in Lucite. The anorthosite sample is a part of the magma ocean formed on the surface of Moon in the early melting period, the basalt is part of the extensive lunar mare lava flows, and the breccias sample is an important example of the violent impact history of the Moon. The disks also include two regolith soils and

    experiences valued by students and instructors. Instructors also valued the activity because of insights into students' understanding that were revealed. This research provides an example of how a student-centered, embodied learning approach can be brought into the undergraduate science classroom. This is valuable because, if instructors are to change from a transmission mode of instruction to more student-centered approaches, they must re-examine and re-construct their practices. An important step in this process is provision of evidence that change is warranted and fruitful.

    Many papers have been written in recent years discussing the interdisciplinary and transdisciplinary aspects of soil science. Therefore, it would make sense that soil science courses would be taken by students in a wide array of academic majors. To investigate this, we collected data from eight different American universities on the declared academic majors of students enrolled in soil science courses over a 10 year time period (2004-2005 to 2013-2014 academic years). Data was collected for seven different classes taught at the undergraduate level: introduction to soil science, soil fertility, soil management, pedology, soil biology/microbiology, soil chemistry, and soil physics. Overall trends and trends for each class were evaluated. Generally, environmental science and crop science/horticulture/agronomy students were enrolled in soil science courses in the greatest numbers. Environmental science and engineering students showed rapid increases in enrollment over the 10 years of the study, while the number of crop science/ horticulture/ agronomy students declined. In the introduction to soil science classes, environmental science and crop science/ horticulture/ agronomy students were enrolled in the greatest numbers, while declared soil science majors only made up 6.6% of the average enrollment. The highest enrollments in soil fertility were crop science/ horticulture/ agronomy students and other agricultural students (all agricultural majors except crop science, horticulture, agronomy, or soil science). In both the soil management and pedology classes, environmental science and other agricultural students were the largest groups enrolled. Other agricultural students and students from other majors (all majors not otherwise expressly investigated) were the largest enrolled groups in soil biology/microbiology courses, and environmental science and soil science students were the largest enrolled groups in soil chemistry classes. Soil physics was the only class

  15. How do Five American Political Science Textbooks Deal with the Economic Dimension?

    DEFF Research Database (Denmark)

    Madsen, Poul Thøis

    2011-01-01

    Politics and economics interact. As a consequence, political science textbooks must often relate to the economic dimension—implicitly or explicitly. But we know very little about how these textbooks relate to economics. Are they merely unreflective customers of neoclassical economics or do...... they strive for a cross-disciplinary approach? An analysis of five American textbooks identifies two very different and concurrent interactions between politics and economics. The first is a theoretically conceived market economy in which market forces independently drive growth and create equilibrium, where...... politics has a rather secluded role. The second is the actually existing mixed economy, characterized by increased inequality, economic concentration, power, and environmental problems, influenced by a state forced to regulate. The problems of operating with such a dichotomy— and possible solutions...

  16. Solid state insurrection how the science of substance made American physics matter

    CERN Document Server

    Martin, Joseph D

    2018-01-01

    Solid state physics—the study of the physical properties of solid matter—was far and away the most populous subfield of Cold War American physics. But despite prolific contributions to consumer and medical technology, such as the transistor and magnetic resonance imaging, it garnered much less professional prestige and public attention than nuclear and particle physics. Solid State Insurrection argues that solid state physics was nonetheless essential to securing the vast social, political, and financial capital Cold War physics enjoyed. Solid state’s technological bent, and its challenge to the “pure science” ideal many physicists cherished, helped physics as a whole respond more readily to Cold War social, political, and economic pressures. Solid state research kept physics economically and technologically relevant, sustaining its lofty cultural standing and policy influence long after the sheen of the Manhattan Project had faded. By placing solid state at the center of the story of twentieth cent...

    The aims of this study were to assess attitudes and behavior of oral health maintenance among students in four faculties (Medicine, Dentistry, Pharmacy, and Allied Health) and to compare oral health attitudes and behavior of all students at Kuwait University Health Sciences Center (KUHSC) based on their academic level. Students enrolled in the Faculties of Dentistry, Medicine, Pharmacy, and Allied Health at KUHSC were evaluated regarding their oral health attitudes and behavior by an e-mail invitation with a link to the Hiroshima University Dental Behavior Inventory survey that was sent to all 1802 students with Kuwait University Health Sciences Center e-mail addresses. The data were analyzed for frequency distributions, and differences among the groups were assessed using the Mann-Whitney U test, Chi-square test, and Kruskal-Wallis test. P values less than 0.05 were considered to be statistically significant ( P < 0.05). The results of this study indicated that dental students achieved better oral health attitudes and behavior than that of their nondental professional fellow students ( P < 0.05). Students in advanced academic levels and female students demonstrated better oral health attitudes and behavior. Dental students and students who were in advanced levels of their training along with female students demonstrated better oral health practices and perceptions than students in lower academic levels and male students, respectively. Additional studies for investigating the effectiveness and identifying areas requiring modification within the dental curriculum at KUHSC may be warranted.

    There has been increasing interest at health science centers in improving the education of health professionals by offering faculty development activities. In 2007-08, as part of an effort to expand education-related faculty development offerings on campus, the University of Tennessee Health Science Center surveyed faculty members in an effort to identify faculty development activities that would be of interest. Factor analysis of survey data indicated that faculty interests in the areas of teaching and learning can be grouped into six dimensions: development of educational goals and objectives, the use of innovative teaching techniques, clinical teaching, improving traditional teaching skills, addressing teaching challenges, and facilitating participation. There were significant differences in the level of interest in education-related faculty development activities by academic rank and by the college of appointment. Full professors expressed somewhat less interest in faculty development activities than faculty members of lower ranks. Faculty members in the Colleges of Medicine and Dentistry expressed somewhat greater interest in faculty development to improve traditional teaching skills. The policy implications of the survey results are discussed, including the need for faculty development activities that target the needs of specific faculty groups.

    The University of Texas-Houston Health Science Center (UT-Houston) has created programs and activities to address the state's pressing needs in minority education. Through InterCon, a network of universities and K-12 schools, UT-Houston works with its partners to identify competitive candidates in the current pool of minority graduates with bachelor's degrees and to help them--along with their non-minority counterparts--progress in their education. Another objective is to expand the pool of minorities underrepresented in medicine who complete high school and go to college. In 1994 UT-Houston and Prairie View A&M University created a collaborative venture to provide new educational opportunities at UT-Houston for Prairie View's predominantly African American students. A three-track summer internship program--a result of that collaboration--has since been expanded to partnerships with other minority and majority universities throughout Texas. In 1998, for example, 108 undergraduate students from these universities (and 40 other universities nationwide) participated in research, professional, and administrative summer internships at UT-Houston. The InterCon network also has partnerships with K-12 schools. UT-Houston works with inner-city, suburban, and rural school districts to develop education models that can be transferred throughout the state. The partnerships deal with helping to teach basic academic skills and computer literacy, improve science-related instruction, meet demands for health promotion materials and information for school-initiated health and wellness programs, and develop distance-learning paradigms. UT-Houston views InterCon as a program helping Texas institutions to engage and adapt to the socioeconomic factors, demographic changes, and technology explosion that currently challenge public education.

    Gyamfi, Alexander

    The purpose of this study was twofold. First, it identified the priority needs common to all science teachers in secondary schools in Kumasi, Ghana. Second, it investigated the relationship existing between the identified priority needs and the teacher demographic variables (type of school, teacher qualification, teaching experience, subject discipline, and sex of teacher) to be used as a basis for implementing in-service education training programs at the Science Resource Centers in Kumasi Ghana. An adapted version of the Moore Assessment Profile (MAP) survey instrument and a set of open-ended questions were used to collect data from the science teachers. The researcher handed out one hundred and fifty questionnaire packets, and all one hundred and fifty (100%) were collected within a period of six weeks. The data were analyzed using descriptive statistics, content analysis, and inferential statistics. The descriptive statistics reported the frequency of responses, and it was used to calculate the Need Index (N) of the identified needs of teachers. Sixteen top-priority needs were identified, and the needs were arranged in a hierarchical order according to the magnitude of the Need Index (0.000 ≤ N ≤ 1.000). Content analysis was used to analyze the responses to the open-ended questions. One-way analysis of variance (ANOVA) was used to test the null hypotheses of the study on each of the sixteen identified top-priority needs and the teacher demographic variables. The findings of this study were as follows: (1) The science teachers identified needs related to "more effective use of instructional materials" as a crucial area for in-service training. (2) Host and Satellite schools exhibited significant difference on procuring supplementary science books for students. Subject discipline of teachers exhibited significant differences on utilizing the library and its facilities by students, obtaining information on where to get help on effective science teaching

    As part of the Basic Science Survey Series for Dentistry, members of the American Dental Education Association (ADEA) Physiology, Pharmacology, and Therapeutics Section surveyed directors of physiology courses in North American dental schools. The survey was designed to assess, among other things, faculty affiliation and experience of course directors, teaching methods, general course content and emphasis, extent of interdisciplinary (shared) instruction, and impact of recent curricular changes. Responses were received from forty-four of sixty-seven (65.7 percent) U.S. and Canadian dental schools. The findings suggest the following: substantial variation exists in instructional hours, faculty affiliation, class size, and interdisciplinary nature of physiology courses; physiology course content emphasis is similar between schools; student contact hours in physiology, which have remained relatively stable in the past fifteen years, are starting to be reduced; recent curricular changes have often been directed towards enhancing the integrative and clinically relevant aspects of physiology instruction; and a trend toward innovative content delivery, such as use of computer-assisted instruction, is evident. Data from this study may be useful to physiology course directors, curriculum committees, and other dental educators with an interest in integrative and interprofessional education.

    This tutorial article provides a concise and pedagogical overview on negatively charged nitrogen-vacancy (NV) centers in diamond. The research on the NV centers has attracted enormous attention for its application to quantum sensing, encompassing the areas of not only physics and applied physics but also chemistry, biology, and life sciences. Nonetheless, its key technical aspects can be understood from the viewpoint of magnetic resonance. We focus on three facets of this ever-expanding research field, to which our viewpoint is especially relevant: microwave engineering, materials science, and magnetometry. In explaining these aspects, we provide a technical basis and up-to-date technologies for research on the NV centers.

    Background Numerous publications demonstrate the importance of community-based participatory research (CBPR) in community health research, but few target the Deaf community. The Deaf community is understudied and underrepresented in health research despite suspected health disparities and communication barriers. Objectives The goal of this paper is to share the lessons learned from the implementation of CBPR in an understudied community of Deaf American Sign Language (ASL) users in the greater Rochester, New York, area. Methods We review the process of CBPR in a Deaf ASL community and identify the lessons learned. Results Key CBPR lessons include the importance of engaging and educating the community about research, ensuring that research benefits the community, using peer-based recruitment strategies, and sustaining community partnerships. These lessons informed subsequent research activities. Conclusions This report focuses on the use of CBPR principles in a Deaf ASL population; lessons learned can be applied to research with other challenging-to-reach populations. PMID:22982845

    1993-01-01

    As this country prepares for exploration to other planets, the need to understand the affects of long duration exposure to microgravity is evident. The National Aeronautics and Space Administration (NASA) Ames Research Center's Space Life Sciences Payloads Office is responsible for a number of non-human life sciences payloads on NASA's Space Shuttle's Spacelab. Included in this responsibility is the training of those individuals who will be conducting the experiments during flight, the astronauts. Preparing a crew to conduct such experiments requires training protocols that build on simple tasks. Once a defined degree of performance proficiency is met for each task, these tasks are combined to increase the complexity of the activities. As tasks are combined into in-flight operations, they are subjected to time constraints and the crew enhances their skills through repetition. The science objectives must be completely understood by the crew and are critical to the overall training program. Completion of the in-flight activities is proof of success. Because the crew is exposed to the background of early research and plans for post-flight analyses, they have a vested interest in the flight activities. The salient features of this training approach is that it allows for flexibility in implementation, consideration of individual differences, and a greater ability to retain experiment information. This training approach offers another effective alternative training tool to existing methodologies.

    Exploiting the information about members of a Social Network (SN) represents one of the most attractive and dwelling subjects for both academic and applied scientists. The community of Complexity Science and especially those researchers working on multiplex social systems are devoting increasing efforts to outline general laws, models, and theories, to the purpose of predicting emergent phenomena in SN's (e.g. success of a product). On the other side the semantic web community aims at engineering a new generation of advanced services tailored to specific people needs. This implies defining constructs, models and methods for handling the semantic layer of SNs. We combined models and techniques from both the former fields to provide a hybrid approach to understand a basic (yet complex) phenomenon: the propagation of individual interests along the social networks. Since information may move along different social networks, one should take into account a multiplex structure. Therefore we introduced the notion of "Semantic Multiplex". In this paper we analyse two different semantic social networks represented by authors publishing in the Computer Science and those in the American Physical Society Journals. The comparison allows to outline common and specific features.

  10. The Science of a Life - Career Path of an African American Geoscientist

    2002-12-01

    A career in the field of geophysical fluid dynamics is not an apparent choice for an African American woman from rural North Carolina. It was, however, the choice made. As a first generation college graduate, the catalyst to pursue such a career path was provided by those external to family; however, internally, the pursuit of education was valued, expected and required. It is this, the expectation and requirement, which serves as the foundation for the discussion of the balance of life in terms of family, education, and career. There are no scales in existence on which to measure the balance of life. The selected educational institutions, Spelman College, The George Washington University, and Princeton University; nor career positions, National Aeronautics and Space Administration, AT&T Bell Laboratories, institutions of higher education, consulting opportunities, discuss, promote or encourage such a balance. Defining this balance, however, is a science that can only be advanced and achieved by the individual in relationship and partnership with community. The science and balance of a life is the focus of this discussion.

  11. Science, technology and innovation policies for development the Latin American experience

    Dutrénit, Gabriela

    2014-01-01

    This book examines the implementation of science, technology and innovation (STI) policy in eight Latin American countries and the different paths these policies have taken. It provides empirical evidence to examine the extent to which STI policies are contributing to the development of the region, as well as to the solution of market failures and the stimulus of the region’s innovation systems. Since the pioneering work of Solow (1957), it has been recognized that innovation is critical for economic growth both in developed and in less-developed countries. Unfortunately Latin America lags behind world trends, and although over the last 20 years the region has established a more stable and certain macroeconomic regime, it is also clear that these changes have not been enough to trigger a process of innovation and productivity to catch-up. Against this rather grim scenario there is some optimism emerging throughout the region. After many years of inaction the region has begun to invest in science, technology...

  12. Evolution and the American social sciences: An evolutionary social scientist's view.

    2004-03-01

    American social scientists rarely ever use evolutionary concepts to explain behavior, despite the potential of such concepts to elucidate major social problems. I argue that this observation can be understood as the product of three influences: an ideologically narrowed political liberalism; a fear of ''Social Darwinism'' as a scientific idea, rather than a scientific apostasy; and a widely believed criticism of evolutionary thinking as deterministic, reductionistic, and Panglossian. I ask what is to be done to encourage social scientists to learn and to apply evolutionary lessons. I answer with four solutions. First, evolutionary social scientists should more effectively educate their non-evolutionary students and colleagues. Second, they should publicize, even popularize, accessible refutations of perennially misleading criticisms. Third, they should more credibly assure skeptics that evolutionary theory not only keeps the ''social'' in social science but better explains social behavior than can any individual-level theory, such as rational-choice theory. Fourth, they should recall that biology took generations to become Darwinian, and they must understand that the social sciences may take as long to become evolutionary.

  15. Balancing acts: A mixed methods study of the figured world of African American 7th graders in urban science classrooms

    Cleveland-Solomon, Tanya E.

    What beliefs and cultural models do youth who are underrepresented in science have about the domain of science and about themselves as science learners? What do they imagine is possible for them in relation to science both now and in the future? In other words, what constitutes their figured world of science? This dissertation study, using a mixed methods design, offers new perspectives on the ways that underrepresented youth's unexamined assumptions or cultural models and resources may shape their identities and motivation to learn science. Through analyses of survey and interview data, I found that urban African American youths' social context, gender, racial identity, and perceptions of the science they had in school influenced their motivation to learn science. Analyses of short-term classroom observations and interviews suggested that students had competing cultural models that they used in their constructions of identities as science learners, which they espoused and adopted in relation to how well they leveraged the science-related cultural resources available to them. Results from this study suggested that these 7th graders would benefit from access to more expansive cultural models through access to individuals with scientific capital as a way to allow them to create fruitful identities as science learners. If we want to ensure that students from groups that are underrepresented in science not only have better outcomes, but aspire to and enter the science career pipeline, we must also begin to support them in their negotiations of competing cultural models that limit their ability to adopt science-learner identities in their classrooms. This study endeavored to understand the particular cultural models and motivational beliefs that drive students to act, and what types of individuals they imagine scientists and science workers to be. This study also examined how cultural models and resources influence identity negotiation, specifically the roles youths

  16. Factors affecting the matriculation of African American undergraduate students in science, mathematics, engineering, and technology

    Hall, Alfred L., II

    Previous research studies indicated that African Americans remain severely underrepresented in the field of science, mathematics, engineering, and technology (SMET), making up only 3% of that workforce, while representing 11.1% of all professional and related workers and 12.6% of the general population. As this country moves towards a more culturally diverse population, then representation of African Americans in SMET-related fields must be addressed in order to ensure our nation's competitiveness in a global market. This research study analyzed characteristics of African American undergraduate SMET majors participating in the Alliance for Minority Participation (AMP) program in six different states located in the Southeast region of the United States. These states consisted of Alabama, Florida, Georgia, Mississippi, North Carolina, and South Carolina. AMP program participants completed a survey questionnaire, which collected information about potential factors that could affect their matriculation in SMET programs of studies at their respective institutions. Follow-up interviews and focus group sessions were also conducted with AMP participants to provide supplemental information to the survey data. The results of student responses were analyzed according to the type of institution the students attended (Historically Black College or University and Majority White Institution) as well as by the statewide Alliance program in which the students were involved. The students responded to survey questions that asked for their reasons for majoring in their field of study, their level of satisfaction with their institution, their impressions of student support programs and persons, their impressions of faculty and advisors, their reasons for thinking of switching majors, and their level of high school preparation. Statistical analyses of the student responses found that African American AMP students attending Historically Black Colleges and Universities differed from those

    This study investigated predictors that influence the science achievement of African-American non-science majors in a Physical Science class. The population consisted of male and female college students enrolled in Physical Science courses at a historical black college or university (HBCU) located in the southeastern portion of the United States. A personal data information sheet was administered to 120 participants during the Fall of 2008. The personal data information sheet consisted of questions pertaining to the high school courses, students took in math, language arts and science. It also consisted of basic background information. Students also gave written consent for their midterm and final grades earned in Physical Science to be used in the study as part of the analyses. A t-Test including chi-square tests revealed that there was not a significant difference in the raw scores of African-American females and African American males on the American College Test. A significant difference was not observed between the females and males on the ACT math subtest, t (118) = -.78, p = .43; reading comprehension subtest, t (118) = -1.44, .15 or on the science reasoning subtest, t (118) = -1.46, p = .15. A significant difference was not found between the final grades of African American females and the final grades of African American males. Chi-square tests were conducted to determine goodness of fit, X2 = 6.11, df = 1, p = .191. Although the grades of females were higher than males, results were not significant. The correlation between math ACT and final grades were not significant, r = .131, N = 120, p = .155, reading comprehension ACT and final grades were not significant, r = .072, N = 120, p = .434 and science reasoning ACT and final grades were found not to be significant, r = .109, N = 120, p = .237. Being that the majority of students who participated in the study were from one state, had similar high school backgrounds, had similar majors and were similar in

    The American Climate Prospectus (ACP), the analysis underlying the Risky Business project, quantitatively assessed the climate risks posed to the United States' economy in six sectors - crop yields, energy demand, coastal property, crime, labor productivity, and mortality [1]. The ACP is unique in its characterization of the full probability distribution of economic impacts of climate change throughout the 21st century, making it an extremely useful basis for risk assessments. Three key innovations allow for this characterization. First, climate projections from CMIP5 models are scaled to a temperature probability distribution derived from a coarser climate model (MAGICC). This allows a more accurate representation of the whole distribution of future climates (in particular the tails) than a simple ensemble average. These are downscaled both temporally and spatially. Second, a set of local sea level rise and tropical cyclone projections are used in conjunction with the most detailed dataset of coastal property in the US in order to capture the risks of rising seas and storm surge. Third, we base many of our sectors on empirically-derived responses to temperature and precipitation. Each of these dose-response functions is resampled many times to populate a statistical distribution. Combining these with uncertainty in emissions scenario, climate model, and weather, we create the full probability distribution of climate impacts from county up to national levels, as well as model the effects upon the economy as a whole. Results are presented as likelihood ranges, as well as changes to return intervals of extreme events. The ACP analysis allows us to compare between sectors to understand the magnitude of required policy responses, and also to identify risks through time. Many sectors displaying large impacts at the end of the century, like those of mortality, have smaller changes in the near-term, due to non-linearities in the response functions. Other sectors, like

    NASA's vast array of scientific data within its Distributed Active Archive Centers (DAACs) is especially valuable to both traditional research scientists as well as the emerging market of Earth Science Information Partners. For example, the air quality science and management communities are increasingly using satellite derived observations in their analyses and decision making. The Air Quality Cluster in the Federation of Earth Science Information Partners (ESIP) uses web infrastructures of interoperability, or Service Oriented Architecture (SOA), to extend data exploration, use, and analysis and provides a user environment for DAAC products. In an effort to continually offer these NASA data to the broadest research community audience, and reusing emerging technologies, both NASA's Goddard Earth Science (GES) and Land Process (LP) DAACs have engaged in a web services pilot project. Through these projects both GES and LP have exposed data through the Open Geospatial Consortiums (OGC) Web Services standards. Reusing several different existing applications and implementation techniques, GES and LP successfully exposed a variety data, through distributed systems to be ingested into multiple end-user systems. The results of this project will enable researchers world wide to access some of NASA's GES & LP DAAC data through OGC protocols. This functionality encourages inter-disciplinary research while increasing data use through advanced technologies. This paper will concentrate on the implementation and use of OGC Web Services, specifically Web Map and Web Coverage Services (WMS, WCS) at GES and LP DAACs, and the value of these services within scientific applications, including integration with the DataFed air quality web infrastructure and in the development of data analysis web applications.

    Since the inception of the P50 Research Center in Injury and Peri-operative Sciences (RCIPS) funding mechanism, the National Institute of General Medical Sciences has supported a team approach to science. Many advances in critical care, particularly burns, have been driven by RCIPS teams. In fact, burns that were fatal in the early 1970s, prior to the inception of the P50 RCIPS program, are now routinely survived as a result of the P50-funded research. The advances in clinical care that led to the reduction in postburn death were made by optimizing resuscitation, incorporating early excision and grafting, bolstering acute care including support for inhalation injury, modulating the hypermetabolic response, augmenting the immune response, incorporating aerobic exercise, and developing antiscarring strategies. The work of the Burn RCIPS programs advanced our understanding of the pathophysiologic response to burn injury. As a result, the effects of a large burn on all organ systems have been studied, leading to the discovery of persistent dysfunction, elucidation of the underlying molecular mechanisms, and identification of potential therapeutic targets. Survival and subsequent patient satisfaction with quality of life have increased. In this review article, we describe the contributions of the Galveston P50 RCIPS that have changed postburn care and have considerably reduced postburn mortality.

  3. The effect of student-centered and teacher-centered instruction with and without conceptual advocacy on biology students' misconceptions, achievement, attitudes toward science, and cognitive retention

    Gallop, Roger Graham

    The purpose of this study was to investigate the effect of student-centered and teacher-centered instructional strategies with and without conceptual advocacy (CA) on ninth-grade biology students' misconceptions (MIS), biology achievement (ACH), attitudes toward science (ATT), and cognitive retention of scientific method and measurement, spontaneous generation, and characteristics of living things. Students were purposively selected using intact classes and assigned to one of four treatment groups (i.e., student-centered instruction without CA, student-centered instruction with CA, teacher-centered instruction with CA, and teacher-centered instruction without CA). A modified quasi-experimental design was used in which students were not matched in the conventional sense but instead, groups were shown to be equivalent on the dependent measure via a pretest. A 5-day treatment implementation period addressed science conceptions under investigation. The treatment period was based on the number of class periods teachers at the target school actually spend teaching the biological concepts under investigation using traditional instruction. At the end of the treatment period, students were posttested using the Concepts in Biology instrument and Science Questionnaire. Eight weeks after the posttest, these instruments were administered again as a delayed posttest to determine cognitive retention of the correct biological conceptions and attitudes toward science. MANCOVA and follow-up univariate ANCOVA results indicated that student-centered instruction without CA (i.e., Group 1) did not have a significant effect on students' MIS, ACH, and ATT (F = .029, p = .8658; F = .002, p =.9688, F = .292, p = .5897, respectively). On the other hand, student-centered instruction with CA (i.e., Group 2) had a significant effect on students' MIS and ACH (F =10.33, p = .0016 and F = 10.17, p = .0017, respectively), but did not on ATT (F = .433, p = .5117).

    This study investigated (a) the stress spillover pathways linking contextual stressors, changes in couple relationship functioning and depressive symptoms, and changes in individuals' physical health, and (b) the stress-buffering effect of participation in an efficacious, family centered prevention program designed to protect couples from the deleterious effects of stressors. The sample consisted of 346 rural African American couples (63% married) who participated in a randomized controlled trial of the Protecting Strong African American Families (ProSAAF) program. Participants were assessed at three time points across 17 months. Results examining stress spillover within the control group indicated that elevated current, but not prior, financial hardship was associated with decreased effective communication, relationship satisfaction, and relationship confidence as well as increased depressive symptoms; current levels of racial discrimination also predicted greater depressive symptoms. Relationship confidence and relationship satisfaction, but not communication or depressive symptoms, in turn predicted declines in self-reported physical health. Results examining stress-buffering effects suggested that participation in ProSAAF protected individuals' relationship confidence from declines associated with elevated financial hardship. In addition, the indirect effect linking financial hardship to declines in physical health through relationship confidence that emerged among participants in the control group was no longer evident for ProSAAF couples. Results highlight the effect of contextual stressors on African Americans' couple and individual well-being and the potential for the ProSAAF program to provide a constructed resilience resource, protecting couple's confidence in their relationship from the negative effects of financial hardship and, consequently, promoting physical health.

    Accurate risk prediction of coronary artery aneurysms (CAAs) in North American children with Kawasaki disease remains a clinical challenge. We sought to determine the predictive utility of baseline coronary dimensions adjusted for body surface area ( z scores) for future CAAs in Kawasaki disease and explored the extent to which addition of established Japanese risk scores to baseline coronary artery z scores improved discrimination for CAA development. We explored the relationships of CAA with baseline z scores; with Kobayashi, Sano, Egami, and Harada risk scores; and with the combination of baseline z scores and risk scores. We defined CAA as a maximum z score (zMax) ≥2.5 of the left anterior descending or right coronary artery at 4 to 8 weeks of illness. Of 261 patients, 77 patients (29%) had a baseline zMax ≥2.0. CAAs occurred in 15 patients (6%). CAAs were strongly associated with baseline zMax ≥2.0 versus Baseline zMax ≥2.0 had a C statistic of 0.77, good sensitivity (80%), and excellent negative predictive value (98%). None of the risk scores alone had adequate discrimination. When high-risk status per the Japanese risk scores was added to models containing baseline zMax ≥2.0, none were significantly better than baseline zMax ≥2.0 alone. In a North American center, baseline zMax ≥2.0 in children with Kawasaki disease demonstrated high predictive utility for later development of CAA. Future studies should validate the utility of our findings. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

    Nowadays we can say that science and technology are development driven forces in most countries, with some exceptions especially in the Southern Hemisphere. Even though, we have to take into account their link to and impact on defense and security and not only when it comes to WMD but also in the economy and academy areas, both in developed and developing countries. Within this framework, when we analyze the spread of technology and knowledge, it is important to consider: the media where it takes place (e.g. journals, internet, conferences, commercial agreements); which the actors involved are (e.g. scientists, governmental agencies, commercial firms); and the motive why it occurs (e.g. scientific discoveries; commercial exchange; international agreements). Once known all these elements, which vary both intracountry and intercountry, we may have a deep and broad enough framework to consider which policies to take in order to foster scientific and technologic development without collaborating with state and non state WMD programs. Although we already have a legal framework to fight against WMD proliferation and terrorism, the diverse degree of success of such instruments makes it necessary to continue analyzing and debating ways to strengthen them and/or find new ones. Therefore, in this paper we will analyze how the phenomena of science and technology development and spread impacts on defense and security from a South American perspective, taking into account the particular differences among developed and developing countries. Among the primary findings we can mention the existing differences between countries when it comes to the place (military, academic or commercial ones) where the critical science and technology innovative developments take place; the origin of funding (private or governmental); the existence and fulfillment of plans to foster science and technology development; and the scientific community awareness in WMD topics. All these elements have a

    NASA is eager for students and the public to experience lunar Apollo samples and meteorites first hand. Lunar rocks and soil, embedded in Lucite disks, are available for educators to use in their classrooms, museums, science centers, and public libraries for education activities and display. The sample education disks are valuable tools for engaging students in the exploration of the Solar System. Scientific research conducted on the Apollo rocks reveals the early history of our Earth-Moon system and meteorites reveal much of the history of the early solar system. The rocks help educators make the connections to this ancient history of our planet and solar system and the basic processes accretion, differentiation, impact and volcanism. With these samples, educators in museums, science centers, libraries, and classrooms can help students and the public understand the key questions pursued by many NASA planetary missions. The Office of the Curator at Johnson Space Center is in the process of reorganizing and renewing the Lunar and Meteorite Sample Education Disk Program to increase reach, security and accountability. The new program expands the reach of these exciting extraterrestrial rocks through increased access to training and educator borrowing. One of the expanded opportunities is that trained certified educators from science centers, museums, and libraries may now borrow the extraterrestrial rock samples. Previously the loan program was only open to classroom educators so the expansion will increase the public access to the samples and allow educators to make the critical connections to the exciting exploration missions taking place in our solar system. Each Lunar Disk contains three lunar rocks and three regolith soils embedded in Lucite. The anorthosite sample is a part of the magma ocean formed on the surface of Moon in the early melting period, the basalt is part of the extensive lunar mare lava flows, and the breccias sample is an important example of the

    Large introductory astronomy and physics survey courses can be very challenging and stressful. The University of Wisconsin-Madison Physics Learning Center (PLC) reaches about 10 percent of the students in four introductory physics courses, algebra and calculus based versions of both classical mechanics and electromagnetism. Participants include those potentially most vulnerable to experiencing isolation and hence to having difficulty finding study partners as well as students struggling with the course. They receive specially written tutorials, conceptual summaries, and practice problems; exam reviews; and most importantly, membership in small groups of 3 - 8 students which meet twice per week in a hybrid of traditional teaching and tutoring. Almost all students who regularly participate in the PLC earn at least a "C,” with many earning higher grades. The PLC works closely with other campus programs which seek to increase the participation and enhance the success of underrepresented minorities, first generation college students, and students from lower-income circumstances; and it is well received by students, departmental faculty, and University administration. The PLC staff includes physics education specialists and research scientists with a passion for education. However, the bulk of the teaching is conducted by undergraduates who are majoring in physics, astronomy, mathematics, engineering, and secondary science teaching (many have multiple majors). The staff train these enthusiastic students, denoted Peer Mentor Tutors (PMTs) in general pedagogy and mentoring strategies, as well as the specifics of teaching the physics covered in the course. The PMTs are among the best undergraduates at the university. While currently there is no UW-Madison learning center for astronomy courses, establishing one is a possible future direction. The introductory astronomy courses cater to non-science majors and consequently are less quantitative. However, the basic structure

    Math and science is the core of science, technology, engineering and math (STEM) education. It is the staying power of economic growth, job opportunities, new technology, innovation and emerging research on a global spectrum in the 21st century. Data reports that African American women are underrepresented in the STEM career field. The focus of this project was to specifically address African American middle school girls achievement gap, awareness and interests in the STEM pipeline. Data for this research was gathered by using Action Research Methodology approach using journals, questionnaire survey and dialogue. Five parents/educators participated in this empirical research study by sharing their personal, lived and unapologetic experiences through eight weeks of action/reflection inquiry. The finding of this research is that parents need to be engaged about STEM and the importance for girls to do well academically early in school with math and science.

    Jéssica Carolinne Damasceno

    Full Text Available ABSTRACT Purpose: Malignant lesions of the eyelid are the most common eye cancers. Although rarely lethal, late diagnosis can lead to serious visual morbidity. Definitive diagnosis of neoplastic lesions is pathological. Indications and types of eyelid lesions in a single high-volume ophthalmic reference center in Sao Paulo, Brazil, were analyzed. Methods: The surgical pathological reports of patients who underwent eye removal procedures between January 2000 and December 2012 were retrieved from the electronic database of the Ophthalmology Department and retrospectively reviewed. Data regarding the final anatomopathological diagnosis, sex, and age were analyzed via the χ2 test with Yates' correction. Results: Of the 1,113 eyelid tumors resected over the 13-year study period, 324 (29% lesions were malignant. The most prevalent lesions were basal cell, squamous cell, and sebaceous gland carcinomas. The median ages of patients (females, n=165, 51%; males, n=159, 49% with a diagnosis of basal cell, squamous cell, and sebaceous gland carcinomas were 65, 75, and 70 years, respectively. Conclusion: This is the largest retrospective cohort analysis of eyelid tumors in a Latin American population. These findings are in agreement with those from large centers in other countries and regions.

    Edwards, Leslie D.

    How do teenage girls develop an interest in science? What kinds of opportunities can science teachers present to female students that support their engagement with learning science? I studied one aspect of this issue by focusing on ways students could use science to enhance or gain identities that they (probably) already valued. To do that I created technology-rich activities and experiences for an after school class in science and technology for middle school girls who lived in a low socio-economic urban neighborhood. These activities and experiences were designed to create a virtual community of practice whose members used science in diverse ways. Student interest was made evident in their responses to the activities. Four conclusions emerged. (1) Opportunities to learn about the lives and work of admired African American business women interested students in learning by linking it to their middle-class aspirations and their interest in things that money and status can buy. (2) Opportunities to learn about the lives and work of African American women experts in science in a classroom context where students then practiced similar kinds of actual scientific tasks engaged students in relations of legitimate peripheral participation in a virtual and diverse community of practice focused on science which was created in the after-school classes. (3) Opportunities where students used science to show off for family, friends, and supporters of the after-school program, identities they valued, interested them enough that they engaged in long-term science and technology projects that required lots of revisions. (4) In response to the opportunities presented, new and enhanced identities developed around becoming a better student or becoming some kind of scientist.

    2012-01-01

    The traditional science lecture, where an instructor delivers a carefully crafted monolog to a large audience of students who passively receive the information, has been a popular mode of instruction for centuries. Recent evidence on the science of teaching and learning indicates that learner-centered, active teaching strategies can be more effective learning tools than traditional lectures. Yet most colleges and universities retain lectures as their central instructional method. This article highlights several simple collaborative teaching techniques that can be readily deployed within traditional lecture frameworks to promote active learning. Specifically, this article briefly introduces the techniques of: reader’s theatre, think-pair-share, roundtable, jigsaw, in-class quizzes, and minute papers. Each technique is broadly applicable well beyond neuroscience courses and easily modifiable to serve an instructor’s specific pedagogical goals. The benefits of each technique are described along with specific examples of how each technique might be deployed within a traditional lecture to create more active learning experiences.

    2016-12-01

    As the landscape of data becomes increasingly more diverse in the domain of Earth Science, the challenges of managing and preserving data become more onerous and complex, particularly for data centers on fixed budgets and limited staff. Many solutions already exist to ease the cost burden for the downstream component of the data lifecycle, yet most archive centers are still racing to keep up with the influx of new data that still needs to find a quasi-permanent resting place. For instance, having well-defined metadata that is consistent across the entire data landscape provides for well-managed and preserved datasets throughout the latter end of the data lifecycle. Translators between different metadata dialects are already in operational use, and facilitate keeping older datasets relevant in today's world of rapidly evolving metadata standards. However, very little is done to address the first phase of the lifecycle, which deals with the entry of both data and the corresponding metadata into a system that is traditionally opaque and closed off to external data producers, thus resulting in a significant bottleneck to the dataset submission process. The ATRAC system was the NOAA NCEI's answer to this previously obfuscated barrier to scientists wishing to find a home for their climate data records, providing a web-based entry point to submit timely and accurate metadata and information about a very specific dataset. A couple of NASA's Distributed Active Archive Centers (DAACs) have implemented their own versions of a web-based dataset and metadata submission form including the ASDC and the ORNL DAAC. The Physical Oceanography DAAC is the most recent in the list of NASA-operated DAACs who have begun to offer their own web-based dataset and metadata submission services to data producers. What makes the PO.DAAC dataset and metadata submission service stand out from these pre-existing services is the option of utilizing both a web browser GUI and a RESTful API to

    Ocean observatories have already demonstrated their ability to maintain long-term time series, capture episodic events, provide context for improved shipboard sampling, and improve accessibility to a broader range of participants. Communicating Ocean Sciences, an already existing college course from COSEE-California has demonstrated its ability to teach future scientists essential communication skills. The NSF-funded Communicating Ocean Sciences to Informal Audiences (COSIA) project has leveraged these experiences and others to demonstrate a long-term model for promoting effective science communication skills and techniques applicable to diverse audiences. The COSIA effort is one of the pathfinders for ensuring that the new scientific results from the increasing U.S. investments in ocean observatories is effectively communicated to the nation, and will serve as a model for other fields. Our presentation will describe a long-term model for promoting effective science communication skills and techniques applicable to diverse audiences. COSIA established partnerships between informal science education institutions and universities nationwide to facilitate quality outreach by scientists and the delivery of rigorous, cutting edge science by informal educators while teaching future scientists (college students) essential communication skills. The COSIA model includes scientist-educator partnerships that develop and deliver a college course that teaches communication skills through the understanding of learning theory specifically related to informal learning environments and the practice of these skills at aquariums and science centers. The goals of COSIA are to: provide a model for establishing substantive, long-term partnerships between scientists and informal science education institutions to meet their respective outreach needs; provide future scientists with experiences delivering outreach and promoting the broader impact of research; and provide diverse role models

  3. "His Native, Hot Country"1: Racial Science and Environment in Antebellum American Medical Thought.

    Science.gov (United States)

    Willoughby, Christopher D

    2017-07-01

    Relying on a close reading of more than 4,000 medicals student theses, this essay explores the evolving medical approaches to race and environment in the early national and antebellum United States and highlights the role that medical school pedagogy played in disseminating and elaborating racial theory. Specifically, it considers the influence of racial science on medical concepts of the relationship of bodies to climates. At their core, monogenesis-belief in a single, unified human race-and polygenesis-the belief that each race was created separately-were theories about the human body's connections to the natural world. As polygenesis became influential in Atlantic medical thought, physicians saw environmental treatments as a matter of matching bodies to their natural ecology. In the first decades of the nineteenth century, Atlantic physicians understood bodies and places as in constant states of flux. Through proper treatment, people and environments could suffer either degradation or improvement. Practitioners saw African Americans and whites as the same species with their differences being largely superficial and produced by climate. However, by the 1830s and 1840s medical students were learning that each race was inherently different and unalterable by time or temperature. In this paradigm, medical students articulated a vision of racial health rooted in organic relationships between bodies and climates. © The Author 2017. Published by Oxford University Press.

    Inquiry-based science education is an important innovation. Researchers and teachers consider it to be stimulating for pupils' application of research skills, construction of meaning and acquiring scientific knowledge. However, there is ambiguity as to what competencies are required to teach inquiry-based science. Our purpose is to develop a profile of professional competence, required for effective inquiry-based science teaching in primary schools in the Netherlands. This article reviews literature and compares the outcomes to the American National Science Education Standards (NSES). In so doing, it seeks to answer the following research questions: What elements of competencies required by primary school teachers who teach inquiry-based science are mentioned, discussed and researched in recent literature? To what extent are the American NSES (introduced 15 years ago) consistent with elements of competencies found in recent literature? A comprehensive literature review was conducted using Educational Resources Information Centre and Google Scholar databases. Fifty-seven peer-reviewed scientific journal articles from 2004 to 2011 were found using keyword combinations. Analysis of these articles resulted in the identification and classification of 22 elements of competencies. This outcome was compared to the American NSES, revealing gaps in the standards with respect to a lack of focus on how teachers view science teaching and themselves as teachers. We also found that elements of competencies are connected and poor mastery of one may affect a teacher's mastery of another. Therefore, we propose that standards for the Netherlands should be presented in a non-linear, holistic, competence-based model.

    Full Text Available The epidemiology of Chagas disease, until recently confined to areas of continental Latin America, has undergone considerable changes in recent decades due to migration to other parts of the world, including Spain. We studied the prevalence of Chagas disease in Latin American patients treated at a health center in Barcelona and evaluated its clinical phase. We make some recommendations for screening for the disease.We performed an observational, cross-sectional prevalence study by means of an immunochromatographic test screening of all continental Latin American patients over the age of 14 years visiting the health centre from October 2007 to October 2009. The diagnosis was confirmed by serological methods: conventional in-house ELISA (cELISA, a commercial kit (rELISA and ELISA using T cruzi lysate (Ortho-Clinical Diagnostics (oELISA. Of 766 patients studied, 22 were diagnosed with T. cruzi infection, showing a prevalence of 2.87% (95% CI, 1.6-4.12%. Of the infected patients, 45.45% men and 54.55% women, 21 were from Bolivia, showing a prevalence in the Bolivian subgroup (n=127 of 16.53% (95% CI, 9.6-23.39%. ALL THE INFECTED PATIENTS WERE IN A CHRONIC PHASE OF CHAGAS DISEASE: 81% with the indeterminate form, 9.5% with the cardiac form and 9.5% with the cardiodigestive form. All patients infected with T. cruzi had heard of Chagas disease in their country of origin, 82% knew someone affected, and 77% had a significant history of living in adobe houses in rural areas.We found a high prevalence of T. cruzi infection in immigrants from Bolivia. Detection of T. cruzi-infected persons by screening programs in non-endemic countries would control non-vectorial transmission and would benefit the persons affected, public health and national health systems.

    Currently, the NASA Nebula Cloud Computing Platform is available to Agency personnel in a pre-release status as the system undergoes a formal operational readiness review. Over the past year, two projects within the Earth Science Office at NASA Marshall Space Flight Center have been investigating the performance and value of Nebula s "Infrastructure as a Service", or "IaaS" concept and applying cloud computing concepts to advance their respective mission goals. The Short-term Prediction Research and Transition (SPoRT) Center focuses on the transition of unique NASA satellite observations and weather forecasting capabilities for use within the operational forecasting community through partnerships with NOAA s National Weather Service (NWS). SPoRT has evaluated the performance of the Weather Research and Forecasting (WRF) model on virtual machines deployed within Nebula and used Nebula instances to simulate local forecasts in support of regional forecast studies of interest to select NWS forecast offices. In addition to weather forecasting applications, rapidly deployable Nebula virtual machines have supported the processing of high resolution NASA satellite imagery to support disaster assessment following the historic severe weather and tornado outbreak of April 27, 2011. Other modeling and satellite analysis activities are underway in support of NASA s SERVIR program, which integrates satellite observations, ground-based data and forecast models to monitor environmental change and improve disaster response in Central America, the Caribbean, Africa, and the Himalayas. Leveraging SPoRT s experience, SERVIR is working to establish a real-time weather forecasting model for Central America. Other modeling efforts include hydrologic forecasts for Kenya, driven by NASA satellite observations and reanalysis data sets provided by the broader meteorological community. Forecast modeling efforts are supplemented by short-term forecasts of convective initiation, determined by

    Norman, Lashaunda Renea

    This qualitative case study investigated the teaching strategies that improve science learning of African American students. This research study further sought the extent the identified teaching strategies that are used to improve African American science learning reflect culturally responsive teaching. Best teaching strategies and culturally responsive teaching have been researched, but there has been minimal research on the impact that both have on science learning, with an emphasis on the African American population. Consequently, the Black-White achievement gap in science persists. The findings revealed the following teaching strategies have a positive impact on African American science learning: (a) lecture-discussion, (b) notetaking, (c) reading strategies, (d) graphic organizers, (e) hands-on activities, (f) laboratory experiences, and (g) cooperative learning. Culturally responsive teaching strategies were evident in the seventh-grade science classrooms observed. Seven themes emerged from this research data: (1) The participating teachers based their research-based teaching strategies used in the classroom on all of the students' learning styles, abilities, attitudes towards science, and motivational levels about learning science, with no emphasis on the African American student population; (2) The participating teachers taught the state content standards simultaneously using the same instructional model daily, incorporating other content areas when possible; (3) The participating African American students believed their seventh-grade science teachers used a variety of teaching strategies to ensure science learning took place, that science learning was fun, and that science learning was engaging; (4) The participating African American students genuinely liked their teacher; (5) The participating African American students revealed high self-efficacy; (6) The African American student participants' parents value education and moved to Success Middle School

  17. Integrating Climate and Ecosystem-Response Sciences in Temperate Western North American Mountains: The CIRMOUNT Initiative

    Millar, C. I.; Fagre, D. B.

    2004-12-01

    Mountain regions are uniquely sensitive to changes in climate, vulnerable to climate effects on biotic and physical factors of intense social concern, and serve as critical early-warning systems of climate impacts. Escalating demands on western North American (WNA) mountain ecosystems increasingly stress both natural resources and rural community capacities; changes in mountain systems cascade to issues of national concern. Although WNA has long been a focus for climate- and climate-related environmental research, these efforts remain disciplinary and poorly integrated, hindering interpretation into policy and management. Knowledge is further hampered by lack of standardized climate monitoring stations at high-elevations in WNA. An initiative is emerging as the Consortium for Integrated Climate Research in Western Mountains (CIRMOUNT) whose primary goal is to improve knowledge of high-elevation climate systems and to better integrate physical, ecological, and social sciences relevant to climate change, ecosystem response, and natural-resource policy in WNA. CIRMOUNT seeks to focus research on climate variability and ecosystem response (progress in understanding synoptic scale processes) that improves interpretation of linkages between ecosystem functions and human processing (progress in understanding human-environment integration), which in turn would yield applicable information and understanding on key societal issues such as mountains as water towers, biodiversity, carbon forest sinks, and wildland hazards such as fire and forest dieback (progress in understanding ecosystem services and key thresholds). Achieving such integration depends first on implementing a network of high-elevation climate-monitoring stations, and linking these with integrated ecosystem-response studies. Achievements since 2003 include convening the 2004 Mountain Climate Sciences Symposium (1, 2) and several special sessions at technical conferences; initiating a biennial mountain climate

    The study investigated Latina and European American adolescent girls’ (N = 345, M = 15.2 years, range = 13 to 18) experiences with academic sexism in mathematics and science (M/S) and their M/S perceived competence and M/S value (liking and importance). M/S academic sexism was based on girls’ reported experiences hearing sexist comments about girls’ abilities in math and science. Older European American adolescents, and both younger and older Latina adolescents, who experienced several instances of academic sexism felt less competent in M/S than girls who experienced less sexism (controlling for M/S grades). In addition, among older girls (regardless of ethnicity), those who experienced several instances of academic sexism valued M/S less than girls who experienced less sexism. PMID:21212810

  9. Science, humanism, judgement, ethics: person-centered medicine as an emergent model of modern clinical practice.

    Science.gov (United States)

    Miles, Andrew

    2013-01-01

    The Medical University of Plovdiv (MUP) has as its motto 'Committed to humanity". But what does humanity in modern medicine mean? Is it possible to practise a form of medicine that is without humanity? In the current article, it is argued that modern medicine is increasingly being practised in a de-personalised fashion, where the patient is understood not as a unique human individual, a person, but rather as a subject or an object and more in the manner of a complex biological machine. Medicine has, it is contended, become distracted from its duty to care, comfort and console as well as to ameliorate, attenuate and cure and that the rapid development of medicine's scientific knowledge is, paradoxically, principally causative. Signal occurrences in the 'patient as a person' movement are reviewed, together with the emergence of the evidence-based medicine (EBM) and patient-centered care (PCC) movements. The characteristics of a model of medicine evolving in response to medicine's current deficiencies--person-centered healthcare (PCH)--are noted and described. In seeking to apply science with humanism, via clinical judgement, within an ethical framework, it is contended that PCH will prove to be far more responsive to the needs of the individual patient and his/her personal circumstances than current models of practice, so that neither a reductive anatomico-pathological, disease-centric model of illness (EBM), nor an aggressive patient-directed, consumerist form of care (PCC) is allowed continued dominance within modern healthcare systems. In conclusion, it is argued that PCH will enable affordable advances in biomedicine and technology to be delivered to patients within a humanistic framework of clinical practice that recognises the patient as a person and which takes full account of his/her stories, values, preferences, goals, aspirations, fears, worries, hopes, cultural context and which responds to his/her psychological, emotional, spiritual and social necessities

    Adalimumab is a fully-human antibody that inhibits TNF alpha, with a significant efficacy for long-term maintenance of remission. Studies with this agent in Latin American Crohn's disease patients are scarce. The objective of this study was to outline clinical remission rates after 12 months of adalimumab therapy for Crohn's disease patients. Retrospective, single-center, observational study of a Brazilian case series of Crohn's disease patients under adalimumab therapy. Variables analyzed: demographic data, Montreal classification, concomitant medication, remission rates after 1, 4, 6 and 12 months. Remission was defined as Harvey-Bradshaw Index ≤ 4, and non-responder-imputation and last-observation-carried-forward analysis were used. The influence of infliximab on remission rates was analyzed by Fischer and Chi-square tests (Panalysis. After 12 months, remission on patients with previous infliximab occurred in 69.23% as compared to 94.59% in infliximab-naïve patients (P = 0.033). Adalimumab was effective in maintaining clinical remission after 12 months of therapy, with an adequate safety profile, and was also more effective in infliximab naïve patients.

  11. Variation in Nest Temperatures of the American Alligator Found on the Kennedy Space Center Merritt Island National Wildlife Refuge

    Information on nest temperatures of the American Alligator (Alligator mississippiensis) constructed in the wild is limited. Nesting temperatures during a critical thermal sensitive period determine the sex of alligators and are therefore critical in establishing the sex biases in recruitment efforts of alligators within a given community. Nest components, varying environmental conditions, and global warming could have a significant impact on nest temperatures, thus affecting future generations of a given population. One hundred and seventy four programmable thermistors were inserted into fifty eight nests from 2010 through 2015 nesting cycles. Three thermistors were placed inside each nest cavity (one on top of the eggs, one in the middle of the eggs, and one at the bottom of the clutch of the eggs) to collect temperature profiles in the incubation chamber and throughout the entire incubation period. One thermistor was also placed near or above these nests to obtain an ambient air temperature profile. Once retrieved, data from these thermistors were downloaded to examine temperature profiles throughout the incubation period as well as during the period of sexual determination. These data would help establish survival rates related to nest temperature and predict sex ratio of recruited neonates at the Kennedy Space Center. Over three million temperatures have been recorded since 2010 for the alligator thermistor study giving us insight to the recruitment efforts found here. Precipitation was the largest influence on nesting temperatures outside of daily photoperiod, with immediate changes of up to eight degrees Celsius.

    The 45th Weather Squadron (45 WS) Launch Weather Officers (LWO's) use the 12-km resolution North American Mesoscale (NAM) model (MesoNAM) text and graphical product forecasts extensively to support launch weather operations. However, the actual performance of the model at Kennedy Space Center (KSC) and Cape Canaveral Air Force Station (CCAFS) has not been measured objectively. In order to have tangible evidence of model performance, the 45 WS tasked the Applied Meteorology Unit (AMU; Bauman et ai, 2004) to conduct a detailed statistical analysis of model output compared to observed values. The model products are provided to the 45 WS by ACTA, Inc. and include hourly forecasts from 0 to 84 hours based on model initialization times of 00, 06, 12 and 18 UTC. The objective analysis compared the MesoNAM forecast winds, temperature (T) and dew pOint (T d), as well as the changes in these parameters over time, to the observed values from the sensors in the KSC/CCAFS wind tower network shown in Table 1. These objective statistics give the forecasters knowledge of the model's strengths and weaknesses, which will result in improved forecasts for operations.

  13. Increasing Access to Atmospheric Science Research at NASA Langley Research Center

    2013-12-01

    The Science Directorate (SD) at NASA's Langley Research Center conducts cutting edge research in fundamental atmospheric science topics including radiation and climate, air quality, active remote sensing, and upper atmospheric composition. These topics matter to the public, as they improve our understanding of our home planet. Thus, we have had ongoing efforts to improve public access to the results of our research. These efforts have accelerated with the release of the February OSTP memo. Our efforts can be grouped in two main categories: 1. Visual presentation techniques to improve science understanding: For fundamental concepts such as the Earth's energy budget, we have worked to display information in a more "digestible" way for lay audiences with more pictures and fewer words. These audiences are iPad-lovers and TV-watchers with shorter attention spans than audiences of the past. They are also educators and students who need a basic understanding of a concept delivered briefly to fit into busy classroom schedules. We seek to reach them with a quick, visual message packed with important information. This presentation will share several examples of visual techniques, such as infographics (e.g., a history of lidar at Langley and a timeline of atmospheric research, ozone garden diagrams (http://science-edu.larc.nasa.gov/ozonegarden/ozone-cycle.php); history of lidar at LaRC; DISCOVER-AQ maps. It will also share examples of animations and interactive graphics (DISCOVER-AQ); and customized presentations (e.g., to explain the energy budget or to give a general overview of research). One of the challenges we face is a required culture shift between the way scientists traditionally share knowledge with each other and the way these public audiences ingest knowledge. A cross-disciplinary communications team in SD is crucial to bridge that gap. 2. Lay research summaries to make research more accessible: Peer-reviewed publications are a primary product of the SD, with more

    The Los Alamos Neutron Science Center (LANSCE) is a large spallation neutron complex centered around an 800 MeV high-currently proton accelerator. Existing facilities include a highly-moderated neutron facility (Lujan Center) where neutrons between thermal and keV energies are produced, and the Weapons Neutron Research Center (WNR), where a bare spallation target produces neutrons between 0.1 and several hundred MeV.The LANSCE facility offers a unique capability to provide high precision nuclear data over a large energy region, including that for fast reactor systems. In an ongoing experimental program the fission and capture cross sections are being measured for a number of minor actinides relevant for Generation-IV reactors and transmutation technology. Fission experiments makes use of both the highly moderated spallation neutron spectrum at the Lujan Center, and the unmoderated high energy spectrum at WNR. By combininb measurements at these two facilities the differential fission cross section is measured relative to the {sup 235}U(n,f) standard from subthermal energies up to about 200 MeV. An elaborate data acquisition system is designed to deal with all the different types of background present when spanning 10 energy decades. The first isotope to be measured was {sup 237}Np, and the results were used to improve the current ENDF/B-VII evaluation. Partial results have also been obtained for {sup 240}Pu and {sup 242}Pu, and the final results are expected shortly. Capture cross sections are measured at LANSCE using the Detector for Advanced Neutron Capture Experiments (DANCE). This unique instrument is highly efficient in detecting radiative capture events, and can thus handle radioactive samples of half-lives as low as 100 years. A number of capture cross sections important to fast reaction applications have been measured with DANCE. The first measurement was on {sup 237}Np(n,{gamma}), and the results have been submitted for publication. Other capture

    1984-01-01

    This report presents the key results of the Phase II efforts for the Intermediate PV System Applications Experiment at the Oklahoma Center for Science and Arts (OCSA). This phase of the project involved fabrication, installation and integration of a nominal 140 kW flat panel PV system made up of large, square polycrystalline-silicon solar cell modules, each nominally 61 cm x 122 cm in size. The output of the PV modules, supplied by Solarex Corporation, was augmented, 1.35 to 1 at peak, by a row of glass reflectors, appropriately tilted northward. The PV system interfaces with the Oklahoma Gas and Electric Utility at the OCSA main switchgear. Any excess power generated by the system is fed into the utility under a one to one buyback arrangement. Except for a shortfall in the system output, presently suspected to be due to the poor performance of the modules, no serious problems were encountered. Certain value engineering changes implemented during construction and early operational failure events associated with the power conditioning system are also described. The system is currently undergoing extended testing and evaluation.

    The Global-scale Observations of the Limb and Disk (GOLD) instrument is an imaging spectrograph to be launched onboard a commercial communications satellite in 2017. From its vantage point in geosynchronous orbit GOLD will image the Earth in the far-ultraviolet from 132 to 162 nm. The instrument consists of two independent optical channels, allowing for simultaneous implementation of multiple measurement sequences with different temporal sampling and spectral resolution. In addition to continuously scanning the disk of the Earth, GOLD will also perform routine limb scan and stellar occultation measurements. These measurements will be used to retrieve a variety of data products characterizing the temperature and composition of the thermosphere-ionosphere, and their response to geomagnetic storms and solar forcing. Primary data products include: daytime neutral temperatures near 160 km altitude; daytime O/N2 column density ratios; nighttime peak electron density; thermospheric O2 density profiles (day and night); daytime exospheric neutral temperature on the limb; atmospheric tides from temperature perturbations; and the location and evolution of ionospheric bubbles. GOLD data will be processed at the Science Data Center (SDC) located at the University of Central Florida. The SDC will also serve as the primary gateway for distribution of GOLD data products to end-users. In this talk we summarize the heritage and theoretical basis of the GOLD retrieval algorithms and describe the full range of GOLD data products that will be available at the SDC, including estimates of data latency and quality.

    To understand the nature of excellent clinicians at an academic health science center by exploring how and why excellent clinicians achieve high performance. From 2008 to 2010, the authors conducted a qualitative study using a grounded theory approach. Members of the Clinical Advisory Committee in the Department of Pediatrics at the University of Toronto nominated peers whom they saw as excellent clinicians. The authors then conducted in-depth interviews with the most frequently nominated clinicians. They audio-recorded and transcribed the interviews and coded the transcripts to identify emergent themes. From interviews with 13 peer-nominated, excellent clinicians, a model emerged. Dominant themes fell into three categories: (1) core philosophy, (2) deliberate activities, and (3) everyday practice. Excellent clinicians are driven by a core philosophy defined by high intrinsic motivation and passion for patient care and humility. They refine their clinical skills through two deliberate activities-reflective clinical practice and scholarship. Their high performance in everyday practice is characterized by clinical skills and cognitive ability, people skills, engagement, and adaptability. A rich theory emerged explaining how excellent clinicians, driven by a core philosophy and engaged in deliberate activities, achieve high performance in everyday practice. This theory of the nature of excellent clinicians provides a holistic perspective of individual performance, informs medical education, supports faculty career development, and promotes clinical excellence in the culture of academic medicine.

    The power reactor industry emerged from extensive research and development performed at nonpower reactors (NPRs). As the industry matures, NPRs continue to support and enhance power reactor technology. With the closure of many government and private industry NPRS, there is an increasing call for the 33 universities with operating research reactors to provide the needed services. The Penn State Radiation Science and Engineering Center (RSEC) includes a 1-MW pool-type pulsing TRIGA reactor, a neutron beam laboratory with real-time neutron radiography equipment, hot cells with master-slave manipulators for remote handling of radioactive materials, a gamma-ray irradiation pool, a low-level radiation monitoring laboratory, and extensive equipment for radiation monitoring, dosimetry, and material properties determination. While equipment is heavily utilized in the instructional and academic research programs, significant time remains available for service work. Cost recovery for service work generates income for personnel, equipment maintenance, and facility improvements. With decreasing federal and state funding for educational programs, it is increasingly important that facilities be fully utilized to generate supplementary revenue. The following are examples of such work performed at the RSEC

    2014-01-01

    A Decision Support System (DSS) can be defined in many ways. The working definition used by the U.S. Geological Survey Upper Midwest Environmental Sciences Center (UMESC) is, “A spatially based computer application or data that assists a researcher or manager in making decisions.” This is quite a broad definition—and it needs to be, because the possibilities for types of DSSs are limited only by the user group and the developer’s imagination. There is no one DSS; the types of DSSs are as diverse as the problems they help solve. This diversity requires that DSSs be built in a variety of ways, using the most appropriate methods and tools for the individual application. The skills of potential DSS users vary widely as well, further necessitating multiple approaches to DSS development. Some small, highly trained user groups may want a powerful modeling tool with extensive functionality at the expense of ease of use. Other user groups less familiar with geographic information system (GIS) and spatial data may want an easy-to-use application for a nontechnical audience. UMESC has been developing DSSs for almost 20 years. Our DSS developers offer our partners a wide variety of technical skills and development options, ranging from the most simple Web page or small application to complex modeling application development.

  1. How to Lead the Way Through Complexity, Constraint, and Uncertainty in Academic Health Science Centers.

    2017-05-01

    Academic medicine is in an era of unprecedented and constant change due to fluctuating economies, globalization, emerging technologies, research, and professional and educational mandates. Consequently, academic health science centers (AHSCs) are facing new levels of complexity, constraint, and uncertainty. Currently, AHSC leaders work with competing academic and health service demands and are required to work with and are accountable to a diversity of stakeholders. Given the new challenges and emerging needs, the authors believe the leadership methods and approaches AHSCs have used in the past that led to successes will be insufficient. In this Article, the authors propose that AHSCs will require a unique combination of old and new leadership approaches specifically oriented to the unique complexity of the AHSC context. They initially describe the designer (or hierarchical) and heroic (military and transformational) approaches to leadership and how they have been applied in AHSCs. While these well-researched and traditional approaches have their strengths in certain contexts, the leadership field has recognized that they can also limit leaders' abilities to enable their organizations to be engaged, adaptable, and responsive. Consequently, some new approaches have emerged that are taking hold in academic work and professional practice. The authors highlight and explore some of these new approaches-the authentic, self, shared, and network approaches to leadership-with attention to their application in and utility for the AHSC context.

  3. "Speak to the eyes, as well as the understanding": The pedagogy of science in Early American higher education, 1750--1830

    Science.gov (United States)

    Spicher, Nicholas

    This dissertation describes the teaching methods and educational philosophies of natural philosophy instructors at several of the colleges in colonial and early national North America. It finds two distinct approaches: the demonstrative, in which the instructor centers the course on visually engaging lecture-demonstrations, and the catechetical, in which the course objective is to master a set of facts and definitions through memorization and repetition. The roots of the demonstrative approach lay in the culture of public lecture-demonstrations that emerged in western Europe during the Scientific Revolution and Enlightenment. The catechism, while having a much longer history as a religious teaching tool, gained new currency in the period through the concern for moral education. Ultimately, both approaches were intimately tied to European Enlightenment ideas about the place of science in the public sphere and the means by which the human mind learns new information. Individual schools, and even individual instructors, had great discretion in choosing which approach, or combination of approaches, to use. Instructors could present lecture-demonstrations as part of the social training of students, who as citizens would be expected to attend lectures and participate in scientifically-informed discussion. Catechetical lessons, however, would be more useful to instructors who favored keeping natural philosophy similar in appearance to other subjects. The catechism, with its systematic presentation and familiar format, was more readily adapted to examinations. Two instructors in particular---William Smith and John Ewing, both at the University of Pennsylvania---serve as exemplars of the demonstrative and catechetical methods, respectively. The recognition of these two approaches, and the larger recognition of the prominence of natural philosophy in the North American curriculum, has implications for the received narratives of both early American science and early American

    We conducted a comprehensive bibliometrics analysis to calculate the H, G, M, A and R indicators for all Iranian biomedical research centers (IBRCs) from the output of ISI Web of Science (WoS) and Scopus between 1991 and 2010. We compared the research performance of the research centers according to these indicators. This was a cross-sectional and descriptive-analytical study, conducted on 104 Iranian biomedical research centers between August and September 2011. We collected our data through Scopus and WoS. Pearson correlation coefficient between the scientometrics indicators was calculated using SPSS, version 16. The mean values of all indicators were higher in Scopus than in WoS. Drug Applied Research Center of Tabriz University of Medical Sciences had the highest number of publications in both WoS and Scopus databases. This research center along with Royan Institute received the highest number of citations in both Scopus and WoS, respectively. The highest correlation was seen between G and R (.998) in WoS and between G and R (.990) in Scopus. Furthermore, the highest overlap of the 10 top IBRCs was between G and H in WoS (100%) and between G-R (90%) and H-R (90%) in Scopus. Research centers affiliated to the top ranked Iranian medical universities obtained a better position with respect to the studied scientometrics indicators. All aforementioned indicators are important for ranking bibliometrics studies as they refer to different attributes of scientific output and citation aspects.

    Essien-Wood, Idara R.

    Given the lack of literature on Undergraduate African American females in the sciences (UAAFS), this study sought to explicate their experiences at one large, predominantly White, Research I institution in the southwestern United States. In particular, the purpose of this study was to identify factors that affect the academic success and persistence of Black females in the natural and physical sciences. Data was collected via in-depth, semi-structured interviews with 15 Black female science majors. Findings from this study identified several supportive mechanisms for academic success: family, religion, teaching assistants and friends. Also identified were seven barriers to academic success: employment, lack of diversity, cultural dissonance, unwelcoming Research I environment, faculty, advisors, classmates, and lab groups. Further, an analysis of students' responses revealed numerous instances of racial and gender micro-aggressions. Recommendations are provided to address factors identified as affecting student academic success and persistence as well as a culture of micro-aggressive behavior.

    In 2010/2011 the Global Data Assembly Center (GDAC) at NASA's Physical Oceanography Distributed Active Archive Center (PO.DAAC) continued its role as the primary clearinghouse and access node for operational Group for High Resolution Sea Surface Temperature (GHRSST) datastreams, as well as its collaborative role with the NOAA Long Term Stewardship and Reanalysis Facility (LTSRF) for archiving. Here we report on our data management activities and infrastructure improvements since the last science team meeting in June 2010.These include the implementation of all GHRSST datastreams in the new PO.DAAC Data Management and Archive System (DMAS) for more reliable and timely data access. GHRSST dataset metadata are now stored in a new database that has made the maintenance and quality improvement of metadata fields more straightforward. A content management system for a revised suite of PO.DAAC web pages allows dynamic access to a subset of these metadata fields for enhanced dataset description as well as discovery through a faceted search mechanism from the perspective of the user. From the discovery and metadata standpoint the GDAC has also implemented the NASA version of the OpenSearch protocol for searching for GHRSST granules and developed a web service to generate ISO 19115-2 compliant metadata records. Furthermore, the GDAC has continued to implement a new suite of tools and services for GHRSST datastreams including a Level 2 subsetter known as Dataminer, a revised POET Level 3/4 subsetter and visualization tool, a Google Earth interface to selected daily global Level 2 and Level 4 data, and experimented with a THREDDS catalog of GHRSST data collections. Finally we will summarize the expanding user and data statistics, and other metrics that we have collected over the last year demonstrating the broad user community and applications that the GHRSST project continues to serve via the GDAC distribution mechanisms. This report also serves by extension to summarize the

    2011-12-01

    Currently, the NASA Nebula Cloud Computing Platform is available to Agency personnel in a pre-release status as the system undergoes a formal operational readiness review. Over the past year, two projects within the Earth Science Office at NASA Marshall Space Flight Center have been investigating the performance and value of Nebula's "Infrastructure as a Service", or "IaaS" concept and applying cloud computing concepts to advance their respective mission goals. The Short-term Prediction Research and Transition (SPoRT) Center focuses on the transition of unique NASA satellite observations and weather forecasting capabilities for use within the operational forecasting community through partnerships with NOAA's National Weather Service (NWS). SPoRT has evaluated the performance of the Weather Research and Forecasting (WRF) model on virtual machines deployed within Nebula and used Nebula instances to simulate local forecasts in support of regional forecast studies of interest to select NWS forecast offices. In addition to weather forecasting applications, rapidly deployable Nebula virtual machines have supported the processing of high resolution NASA satellite imagery to support disaster assessment following the historic severe weather and tornado outbreak of April 27, 2011. Other modeling and satellite analysis activities are underway in support of NASA's SERVIR program, which integrates satellite observations, ground-based data and forecast models to monitor environmental change and improve disaster response in Central America, the Caribbean, Africa, and the Himalayas. Leveraging SPoRT's experience, SERVIR is working to establish a real-time weather forecasting model for Central America. Other modeling efforts include hydrologic forecasts for Kenya, driven by NASA satellite observations and reanalysis data sets provided by the broader meteorological community. Forecast modeling efforts are supplemented by short-term forecasts of convective initiation, determined by

    The Resuscitation Science Symposium (ReSS) is the dedicated international forum for resuscitation science at the American Heart Association's Scientific Sessions. In an attempt to increase curated content and social media presence during ReSS 2017, the Journal of the American Heart Association (JAHA) coordinated an inaugural social media campaign. Before ReSS, 8 resuscitation science professionals were recruited from a convenience sample of attendees at ReSS 2017. Each blogger was assigned to either a morning or an afternoon session, responsible for "live tweeting" with the associated hashtags #ReSS17 and #AHA17. Twitter analytics from the 8 bloggers were collected from November 10 to 13, 2017. The primary outcome was Twitter impressions. Secondary outcomes included Twitter engagement and Twitter engagement rate. In total, 8 bloggers (63% male) generated 591 tweets that garnered 261 050 impressions, 8013 engagements, 928 retweets, 1653 likes, 292 hashtag clicks, and a median engagement rate of 2.4%. Total engagement, likes, and hashtag clicks were highest on day 2; total impressions were highest on day 3, and retweets were highest on day 4. Total impressions were highly correlated with the total number of tweets ( r =0.87; P =0.005) and baseline number of Twitter followers for each blogger ( r =0.78; P =0.02). In this inaugural social media campaign for the 2017 American Heart Association ReSS, the degree of online engagement with this content by end users was quite good when evaluated by social media standards. Benchmarks for end-user interactions in the scientific community are undefined and will require further study. © 2018 The Authors.

    The George Kuzmycz Training Center for Physical Protection, Control and Accounting of Nuclear Material (GKTC) was established in October 1998 at the Kiev Institute for Nuclear Research. During the past six years, about 700 professionals from all Ukrainian nuclear installations, executive and regulatory bodies were trained at the GKTC. Future Material Control and Accounting (MC and A) training courses are going to be held even more frequently because Ukraine has already signed the Additional Model Protocol and its ratification by Ukrainian Parliament is expected to happen very soon. Additionally, a number of new training courses will be developed. US DOE trough Argonne National Laboratory has made significant efforts to transfer Automated Inventory/Material Accounting System (AIMAS) software to Ukraine. As a result, AIMAS software can be used as a basic code for the development of the Computerized MC and A System for all Ukrainian nuclear facilities despite their differences. In 2003, a new laboratory for Nondestructive Assay (NDA) was established with assistance from the U.S. Department of Energy. As a result, GKTC training capabilities will increase substantially. Furthermore, in order to increase the efficiency of NDA laboratory, it is planned to use the NDA equipment for a program of interdiction of illicit traffic of nuclear materials in Ukraine. American-Ukrainian MC and A efforts for the last 6 years, the problems encountered and the solutions to these problems, as well as comments, suggestions and recommendations for future activity at GKTC to promote and improve the nuclear material management culture in Ukraine are discussed in detail.

  14. Media influence on pre-middle school African Americans' perceptions toward science, mathematics, and technology courses and careers

    Waters, Sharon Campbell

    2005-07-01

    A variety of previous studies have suggested that inaccurate, stereotypical or missing media depictions of science, engineering, and technology (SET) workers and fields have contributed to a growing shortage of youth interested in pursuing careers within the scientific endeavor. However, studies on the perceptions of African American youth have not usually been the focus of such research. In this exploratory study, in-depth interviews were conducted with 34 fifth grade African American students to determine the relative influence television and film portrayals of SET workers had on these children's perceptions of roles in SET fields and careers and school coursework related to them. Framed within the theoretical perspectives of cultivation analysis and the construction of social reality, results indicated the majority of participants perceived scientists as ambiguous, possessing either mythic characteristics of the fantastic persona or they saw them as altruistically inclined figures that saved the world from disease, destruction, and decay. Television and film portrayals of SET workers were found in varying degrees and ways to shape these African American children's perceptions toward SET careers. While children exhibited self-concepts about SET workers that were sometimes idealistic, distorted, or unrealistic, most had favorable perceptions toward math and science courses in school. However, it was the absence of television and film portrayals of African Americans in SET roles that was problematic for the majority of students. Recommendations for media producers, educators, scientific research foundations, and parents were suggested to dispel some of these commonly found media stereotypes of SET workers and African Americans in these roles and their effects.

    A Compton suppression system is used to reduce the contribution of scattered gamma-rays that originate within the HPGe detector to the gamma ray spectrum. The HPGe detector is surrounded by an assembly of guard detectors, usually NaI(Tl). The HPGe and NaI(Tl) detectors are operated in anti-coincidence mode. The NaI(Tl) guard detector detects the photons that Compton scatter within, and subsequently escape from the HPGe detector. Since these photons are correlated with the partial energy deposition within the detector, much of the resulting Compton continuum can be subtracted from the spectrum reducing the unwanted background in gamma-ray spectra. A commercially available Compton suppression spectrometer (CSS) was purchased from Canberra Industries and tested at the Radiation Science and Engineering Center at Penn State University. The PSU-CSS includes a reverse bias HPGe detector, four annulus NaI(Tl) detectors, a NaI(Tl) plug detector, detector shields, data acquisition electronics, and a data processing computer. The HPGe detector is n-type with 54% relative efficiency. The guard detectors form an annulus with 9-inch diameter and 9-inch height, and have a plug detector that goes into/out of the annulus with the help of a special lift apparatus to raise/lower. The detector assembly is placed in a shielding cave. State-of-the-art electronics and software are used. The system was tested using standard sources, neutron activated NIST SRM sample and Dendrochronologically Dated Tree Ring samples. The PSU-CSS dramatically improved the peak-to-Compton ratio, up to 1000 : 1 for the 137 Cs source. (author)

  18. Patterns of biomedical science production in a sub-Saharan research center

    2012-03-01

    Full Text Available Abstract Background Research activities in sub-Saharan Africa may be limited to delegated tasks due to the strong control from Western collaborators, which could lead to scientific production of little value in terms of its impact on social and economic innovation in less developed areas. However, the current contexts of international biomedical research including the development of public-private partnerships and research institutions in Africa suggest that scientific activities are growing in sub-Saharan Africa. This study aims to describe the patterns of clinical research activities at a sub-Saharan biomedical research center. Methods In-depth interviews were conducted with a core group of researchers at the Medical Research Unit of the Albert Schweitzer Hospital from June 2009 to February 2010 in Lambaréné, Gabon. Scientific activities running at the MRU as well as the implementation of ethical and regulatory standards were covered by the interview sessions. Results The framework of clinical research includes transnational studies and research initiated locally. In transnational collaborations, a sub-Saharan research institution may be limited to producing confirmatory and late-stage data with little impact on economic and social innovation. However, ethical and regulatory guidelines are being implemented taking into consideration the local contexts. Similarly, the scientific content of studies designed by researchers at the MRU, if local needs are taken into account, may potentially contribute to a scientific production with long-term value on social and economic innovation in sub-Saharan Africa. Conclusion Further research questions and methods in social sciences should comprehensively address the construction of scientific content with the social, economic and cultural contexts surrounding research activities.

  19. Solid State Power Amplifier for 805 MegaHertz at the Los Alamos Neutron Science Center

    Particle accelerators for protons, electrons, and other ion species often use high-power vacuum tubes for RF amplification, due to the high RF power requirements to accelerate these particles with high beam currents. The final power amplifier stages driving large accelerators are unable to be converted to solid-state devices with the present technology. In some instances, radiation levels preclude the use of transistors near beamlines. Work is being done worldwide to replace the RF power stages under about ten kilowatts CW with transistor amplifiers, due to the lower maintenance costs and obsolescence of power tubes in these ranges. This is especially practical where the stages drive fifty Ohm impedance and are not located in high radiation zones. The authors are doing this at the Los Alamos Neutron Science Center (LANSCE) proton linear accelerator (linac) in New Mexico. They replaced a physically-large air-cooled UHF power amplifier using a tetrode electron tube with a compact water-cooled unit based on modular amplifier pallets developed at LANSCE. Each module uses eight push-pull bipolar power transistor pairs operated in class AB. Four pallets can easily provide up to 2,800 watts of continuous RF at 805 MHz. A radial splitter and combiner parallels the modules. This amplifier has proven to be completely reliable after over 10,000 hours of operation without failure. A second unit was constructed and installed for redundancy, and the old tetrode system was removed in 1998. The compact packaging for cooling, DC power, impedance matching, RF interconnection, and power combining met the electrical and mechanical requirements. CRT display of individual collector currents and RF levels is made possible with built-in samplers and a VXI data acquisition unit

    Purpose One of the major issues faced by academic health science centers (AHSCs) is the need for mechanisms to foster the integration of research, clinical, and educational activities to achieve the vision of evidence-informed decision making (EIDM) and optimal client care. The paper aims to discuss this issue. Design/methodology/approach This paper synthesizes literature on organizational learning and collaboration, evidence-informed organizational decision making, and learning-based organizations to derive insights concerning the nature of effective workplace learning in AHSCs. Findings An evidence-informed model of collaborative workplace learning is proposed to aid the alignment of research, clinical, and educational functions in AHSCs. The model articulates relationships among AHSC academic functions and sub-functions, cross-functional activities, and collaborative learning processes, emphasizing the importance of cross-functional activities in enhancing collaborative learning processes and optimizing EIDM and client care. Cross-functional activities involving clinicians, researchers, and educators are hypothesized to be a primary vehicle for integration, supported by a learning-oriented workplace culture. These activities are distinct from interprofessional teams, which are clinical in nature. Four collaborative learning processes are specified that are enhanced in cross-functional activities or teamwork: co-constructing meaning, co-learning, co-producing knowledge, and co-using knowledge. Practical implications The model provides an aspirational vision and insight into the importance of cross-functional activities in enhancing workplace learning. The paper discusses the conceptual and empirical basis to the model, its contributions and limitations, and implications for AHSCs. Originality/value The model's potential utility for health care is discussed, with implications for organizational culture and the promotion of cross-functional activities.

    A liquid drop model predicts that the fission barrier of a nucleus whose atomic number (Z) is larger than 106 disappears, so that such heavier nuclei as Z > 106 cannot exist. The shell effect, however, drastically changes structure of the fission barrier and stabilizes nucleus against fission, predicting the presence of super heavy element (SHE, Z=114-126) with measurable half-life. In the SHE region, a wave function of outermost electron of an atom, which controls chemical properties of an elements, is disturbed or changed by relativistic effects compared to the one from the non-relativistic model. This suggests that the SHEs have different chemical properties from those of lighter elements belonging to the same family. The chemistry of SHEs requires event by event analysis to reveal their chemical properties, thus is called 'atom-at-a-time chemistry'. Japan Atomic Energy Research Institute (JAERI) has been investigating fusion mechanism between heavy nuclei to find out favorable reactions to produce SHE by using JAERI-tandem and booster accelerator. In the JAERI-tandem facility, isotopes of Rf and Db are produced by using actinide targets such as 248 Cm in order to investigate their chemical properties. The present workshop was held in Advanced Science Research Center of JAERI at February 27-28 (2003) in order to discuss current status and future plans for the heavy element research. The workshop also included topics of the radioactive nuclear beam project forwarded by the JAERI-KEK cooperation and the nuclear transmutation facility of J-PARC. Also included is the nuclear fission process as a decay characteristic of heavy elements. There were sixty participants in the workshop including graduate and undergraduate eleven students. We had guests from Germany and Hungary. Through the workshop, we had a common knowledge that researches on SHE in Japan should fill an important role in the world. (author)

    The Integrated GroundWater Modeling Center (IGWMC) at Colorado School of Mines has, over the past three years, developed a community outreach program focusing on hydrologic science education, targeting K-12 teachers and students, and providing experiential learning for undergraduate and graduate students. During this time, the programs led by the IGWMC reached approximately 7500 students, teachers, and community members along the Colorado Front Range. An educational campaign of this magnitude for a small (2 full-time employees, 4 PIs) research center required restructuring and modularizing of the outreach strategy. We refined our approach to include three main "modules" of delivery. First: grassroots education delivery in the form of K-12 classroom visits, science fairs, and teacher workshops. Second: content development in the form of lesson plans for K-12 classrooms and STEM camps, hands-on physical and computer model activities, and long-term citizen science partnerships. Lastly: providing education/outreach experiences for undergraduate and graduate student volunteers, training them via a 3-credit honors course, and instilling the importance of effective science communication skills. Here we present specific case studies and examples of the successes and failures of our three-pronged system, future developments, and suggestions for entities newly embarking on an earth science education outreach campaign.

    The Japan Nuclear Reaction Data Center (JCPRG) was approved as an organisation of Faculty of Science, Hokkaido University and established on April 1, 2007. In addition to nuclear data activities carried out by JCPRG (Japan-Charged Particle Nuclear Reaction Data Group), the centre is concerned with the evaluation of nuclear reaction data in nucleosynthesis in the universe. In order efficiently to compile reaction data obtained by using radioactive ion beam, the centre signed a research contract with RIKEN Nishina Center. We are scanning 16 journals for Japanese charged-particle and photo-nuclear nuclear reaction data compilation. From April 2006 to March 2007, CPND and PhND in 45 references (453 records, 1.83 MB) have been newly compiled for NRDF. Usually new data are released at the JCPRG web site several months prior to EXFOR. Since the 2006 NRDC meeting, we have made 104 new entries and have revised or deleted 142 old entries. Intensive numerical data compilations have been done. These data were shown in tabular form in dissertations which are (partially) published in Journals. About 30 new entries were compiled from these data. We have prepared CINDA batches for CPND published in Japan every half year. Each batch covers 6 issues of each of 4 Japanese journals JPJ, PTP, NST and JNRS. Bibliographies for neutron induced reaction data have been compiled by JAEA Nuclear Data Center as before. A new web-based NRDF search and plot system on MySQL was released in July, 2007. New compilation, which has been finalized for NRDF, but not for EXFOR, can be obtained from this site. DARPE (another NRDF search and plot system written in Perl) is also available at http://www.jcprg.org/darpe/. EXFOR/ENDF (http://www.jcprg.org/exfor/) search and plot system is available. We have also developed following utilities: PENDL (http://www.jcprg.org/endf/) and RENORM (http://www.jcprg.org/renorm). We are developing a new search system of CINDA. This is an extension of EXFOR/ENDF search

    2000-01-01

    The start of Latin America's love story with fungi may be placed in pre-Hispanic times when the use of fungi in both ritual ceremonies and daily life were common to the native civilizations. But the medical mycology discipline in Latin America started at the end of the 19th Century. At that time, scholars such as A. Posadas, R. Seeber, A. Lutz and P. Almeida, discovered agents of fungal diseases, the study of which has influenced the regional research ever since. Heirs to them are the researchers that today thrive in regional Universities and Research Institutes. Two current initiatives improve cooperation among Latin American medical mycologists. First, the periodical organization of International Paracoccidioidomycosis Meetings (seven so far, from 1979 to 1999); second, the creation of the Latin American Association for Mycology in 1991 (three Congresses, from 1993 to 1999). Latin American publications have increased in international specialized journals such as that from our Society (ISHAM) (from 8% in 1967 to 19% in 1999), and the Iberoamerican Journal of Mycology (Revista Iberoamericana de Micologia; > 40% from 1997 to 1999). In addition, Latin American participation at ISHAM International Congresses has risen from 6.9% in 1975 to 21.3% in 1997, and 43.2% at the 14th ISHAM Congress, held for the first time in a Latin American country, Argentina. A significant contribution of women to the scientific establishment of Latin American medical mycology (e.g., 45% of Latin American papers vs. 18% of other regions published in Journal of Medical and Veterinary Mycology in 1987, had women as authors or coauthors) suggests a better academic consideration of Latin American women against their counterparts in the developed world. Taken together, all these figures reflect the enthusiasm of our Latin American colleagues in the field, despite the difficulties that afflict our region, and affect our work.

  8. American social sciences and Europeanization: theories of integration in the early 1950s

    OpenAIRE

    Anderson, Flora McIntyre

    2017-01-01

    This thesis seeks to investigate the influence of American intellectual trends, namely structural functionalism, on the first fifteen years of Europeanization after the end of World War Two. In particular, it examines the role played by German intellectual refugees in the development of neofunctionalist theories of integration that accompanied American policymaking in this era by focusing on the work of Karl Deutsch and Ernst Haas in the 1940s and 1950s. It analyses their account of the condi...

    Comments on the article "Joint principles: Integrating behavioral health care into the patient-centered medical home" (see record 2014-24217-011), presented by the Working Party Group on Integrated Behavioral Healthcare. The American Psychological Association (APA) shares concerns about the lack of reference to behavioral health care in the original 2007 Joint Principles of the Patient-Centered Medical Home for which this new document is intended to supplement but not replace. The decision to support the supplemental Joint Principles was not an easy one for APA, as there is one area of significant concern. That concern is related to the use of the term "physician-directed medical practice"

  10. Is International Relations still an American social science discipline in Latin America?

    Directory of Open Access Journals (Sweden)

    Rafael A. Duarte Villa

    Full Text Available Abstract Over the last 40 years, investigations have shown the discipline of International Relations to reproduce the American influence on its methods, paradigms, and institutional dynamics. This article explores the case for the Latin American community, based on the survey data from the Teaching, Research, and International Politics project (TRIP 2014 developed by the Institute for the Theory and Practice of International Relations of the College of William and Mary, Virginia (USA. TRIP evaluated International Relations communities in 32 countries around the world. The article aims to answer two main questions: (i is American influence still dominant over epistemological, methodological, paradigmatic, and institutional representative terms in Latin American International Relations communities, as has been considered in the past? (ii Is there in the region any contestation to this supposed influence? Primarily, the present article shows an affirmative answer for the first issue. Therefore, and most importantly, the data analysis shows upcoming local pressures rooted in American influence, especially on its epistemic and paradigmatic terms. The data strengthens the miscegenation tendency on its epistemological and paradigmatic aspects, which underlines a lack of consensus over the structure of American dominance over the discipline of International Relations in Latin America, especially if one observes the most numerous and structured group in the region: the Brazilian International Relations community.

  12. African American women making race work in science, technology, engineering, and math (STEM)

    Galloway, Stephanie Nicole

    African American women maintain distinctive social locations at the intersection of race, gender, and class (Crenshaw, 1991; Collins, 1986; 2000; Wing, 2003). However, their voices, interpretation of experiences, and concern with the use of formal education as a mechanism for racial uplift have not been priorities in feminist movements (hooks, 1981; 1989; Perkins, 1993; Smith, 1998; Spitzack & Carter, 1987). Alternatively, Black feminist thought (Collins, 1990; 2000) is a theory constructed by and for African American women. Given the consequences of pursuing formal education in the histories of African American women and the paucity of African American women represented in STEM fields, the purpose of this study was to (a) reveal how African American women conducting research in STEM disciplines accomplished their professional goals, (b) learn how the women negotiated their multiple identities (i.e. race, gender, and class), (c) link the history of educational experiences among African Americans with agendas for social justice, (d) understand how African American women in STEM align their personal accomplishments with broader agendas for activism in higher education, and (e) discover whether there is a collective identity that successful African American women in STEM share. Using Black feminist thought (Collins, 1986; 2000) and narrative analysis of semi- interviews with eight African American women in STEM, the findings from this study revealed: (a) the women in this study described the challenges of pursuing a career in STEM from a feminist perspective, identifying gender as more significant than race; (b) the women in this study experienced more positive interactions with Black male, White female, and White male mentors than with Black female mentors; (c) the women in this study described the use of empowering strategies for overcoming obstacles in their academic pathways; and (d) their collective academic identities were formed by early interactions with

    The Office of Instruction and Assessment at the University of Arizona currently offers a Certificate in College Teaching Program. The objective of this program is to develop the competencies necessary to teach effectively in higher education today, with an emphasis on learner-centered teaching. This type of teaching methodology has repeatedly shown to have superior effects compared to traditional teacher-centered approaches. The success of this approach has been proven in both short term and long term teaching scenarios. Students must actively participate in class, which allows for the development of depth of understanding, acquisition of critical thinking, and problem-solving skills. As optical science graduate students completing the teaching program certificate, we taught a recitation class for OPTI 370: Photonics and Lasers for two consecutive years. The recitation was an optional 1-hour long session to supplement the course lectures. This recitation received positive feedback and learner-centered teaching was shown to be a successful method for engaging students in science, specifically in optical sciences following an inquiry driven format. This paper is intended as a guide for interactive, multifaceted teaching, due to the fact that there are a variety of learning styles found in every classroom. The techniques outlined can be implemented in many formats: a full course, recitation session, office hours and tutoring. This guide is practical and includes only the most effective and efficient strategies learned while also addressing the challenges faced, such as formulating engaging questions, using wait time and encouraging shy students.

    NASA Johnson Space Center's (JSC's) Astromaterials Research and Exploration Science (ARES) Division, part of the Exploration Integration and Science Directorate, houses a unique combination of laboratories and other assets for conducting cutting edge planetary research. These facilities have been accessed for decades by outside scientists, most at no cost and on an informal basis. ARES has thus provided substantial leverage to many past and ongoing science projects at the national and international level. Here we propose to formalize that support via an ARES/JSC Plane-tary Sample Analysis and Mission Science Laboratory (PSAMS Lab). We maintain three major research capa-bilities: astromaterial sample analysis, planetary process simulation, and robotic-mission analog research. ARES scientists also support planning for eventual human ex-ploration missions, including astronaut geological training. We outline our facility's capabilities and its potential service to the community at large which, taken together with longstanding ARES experience and expertise in curation and in applied mission science, enable multi-disciplinary planetary research possible at no other institution. Comprehensive campaigns incorporating sample data, experimental constraints, and mission science data can be conducted under one roof.

    The present stock and flow of highly talented young persons engaged in the global discovery and application of science and technology are critical to the future pace of innovation. Historically, the world`s largest reservoirs of scientists and engineers have been in the Western economies. Overtime, however, Asia has begun to build equivalent pools of scientists and engineers among their university graduates. According to 1993 data from the National Science Foundation and the UNESCO World Science Report, Germany leads all economies with a 67% ratio of science and engineering degrees to total first university degrees compared to the United States with a distant fifth place at 32% behind Italy, Mexico and Poland. If the nation is to keep its scientific and technological prowess, it must capture its very best talent in the science and technology fields. The question is then raised as to the source within the United States of the science and technology talent pool. While between 1978 and 1991 there was an overall decline in male participation in undergraduate (-9%) and graduate degrees (-12%), the number of women receiving undergraduate (+8%) and graduate degrees (+34%) rose dramatically. These numbers are encouraging for women`s participation overall, however, women earn only a small percentage of physical science and engineering degrees. Why are there so few women in mathematics, engineering, and the physical sciences? The answers are complex and begin early in a woman`s exposure to science and mathematics. This report presents results on a study of careers of alumni from the Research Science Institute. Investigations were concerned with the timing of decision processes concerned with the sciences and math and factors that influenced people to turn away from or proceed with careers in science and math.

    2009-12-01

    The goal of the UMM STEP program is to increase the number of graduates in STEM fields through innovative curricular, recruiting and mentoring strategies. A unique focus of the UMM STEP program is increasing the number of Native American science majors. The STEP program fosters a summer research environment where peer interaction and mentoring creates a web of support. To do so we will establish a supportive and fulfilling pipeline that: 1) Identifies Native American students and involves them in research while they are high school; 2) Mentors and prepares participants for university academics the summer before their freshman year; 3) Provides a complete tuition waiver, mentoring and a support network throughout their undergraduate career; and 4) Involves participants in an active and dynamic summer undergraduate research environment where under-represented individuals are in the majority. The third and fourth components of this pipeline are in very good shape. The Morris campus was originally established as an Indian School in 1887. When the federal government deeded the Indian school campus to the University of Minnesota a stipulation was that Native American students attend the college for free. At present, 196 Native Americans are enrolled at UMM (50 are STEM majors). The UMM STEP research experience provides the unique opportunity to interact with a scientific community that both breaks down a number of traditional barriers and aids in the maturation of these students as scientists. In Summer 2008, 4 students were involved in summer research and in 2009 seven Native American students participated. Early efforts of the UMM STEP program are encouraging. UMM Admissions staff used the UMM STEP program to recruit Native American students and the P.I. phoned “uncommitted admits”, visited reservations and hosted reservation student visits. The result was an increase in freshman Native American Science majors from 7 in Fall 2007, 15 in fall 2008 and 20 in fall

    Increasingly sophisticated National Aeronautics and Space Administration (NASA) Earth science missions have driven their associated data and data management systems from providing simple point-to-point archiving and retrieval to performing user-responsive distributed multisensor information extraction. To fully maximize the use of remote-sensor-generated Earth science data, NASA recognized the need for data systems that provide data access and manipulation capabilities responsive to research brought forth by advancing scientific analysis and the need to maximize the use and usability of the data. The decision by NASA to purposely evolve the Earth Observing System Data and Information System (EOSDIS) at the Goddard Space Flight Center (GSFC) Earth Sciences (GES) Data and Information Services Center (DISC) and other information management facilities was timely and appropriate. The GES DISC evolution was focused on replacing the EOSDIS Core System (ECS) by reusing the In-house developed disk-based Simple, Scalable, Script-based Science Product Archive (S4PA) data management system and migrating data to the disk archives. Transition was completed in December 2007

    This is the 34th Annual Report of the American Association of Poison Control Centers' (AAPCC) National Poison Data System (NPDS). As of 1 January 2016, 55 of the nation's poison centers (PCs) uploaded case data automatically to NPDS. The upload interval was 9.50 [7.33, 14.6] (median [25%, 75%]) min, facilitating a near real-time national exposure and information database and surveillance system. We analyzed the case data tabulating specific indices from NPDS. The methodology was similar to that of previous years. Where changes were introduced, the differences are identified. Cases with medical outcomes of death were evaluated by a team of medical and clinical toxicologist reviewers using an ordinal scale of 1-6 to assess the Relative Contribution to Fatality (RCF) of the exposure. In 2016, 2,710,042 closed encounters were logged by NPDS: 2,159,032 human exposures, 54,019 animal exposures, 490,215 information cases, 6687 human confirmed non-exposures, and 89 animal confirmed non-exposures. US PCs also made 2,718,022 follow-up calls in 2016. Total encounters showed a 2.94% decline from 2015, while health care facility (HCF) human exposure cases increased by 3.63% from 2015. All information calls decreased by 12.5% but HCF information calls increased 0.454%, and while medication identification requests (Drug ID) decreased 29.6%, human exposure cases were essentially flat, decreasing by 0.431%. Human exposures with less serious outcomes have decreased 2.59% per year since 2008 while those with more serious outcomes (moderate, major or death) have increased by 4.39% per year since 2000. The top five substance classes most frequently involved in all human exposures were analgesics (11.2%), household cleaning substances (7.54%), cosmetics/personal care products (7.20%), sedatives/hypnotics/antipsychotics (5.84%), and antidepressants (4.74%). As a class, sedative/hypnotics/antipsychotics exposures increased most rapidly, by 10.7% per year (2088 cases/year), over the last

    This paper describes the interaction of four elements of social science as they have evolved in concert with the Center for Adaptive Optics Professional Development Program (CfAO PDP). We hope these examples persuade early-career scientists and engineers to include social science activities as they develop grant proposals and carry out their research. To frame our discussion we use a metaphor from astronomy. At the University of California Santa Cruz (UCSC), the CfAO PDP and the Educational Partnership Center (EPC) are two young stars in the process of forming a solar system. Together, they are surrounded by a disk of gas and dust made up of program evaluation, applied research, educational assessment, and pedagogy. An idea from the 2001 PDP intensive workshops program evaluation developed into the Assessing Scientific Inquiry and Leadership Skills (AScILS) applied research project. In iterative cycles, AScILS researchers participated in subsequent PDP intensive workshops, teaching social science while piloting AScILS measurement strategies. Subsequent "orbits" of the PDP program evaluation gathered ideas from the applied research and pedagogy. The denser regions of this disk of social science are in the process of forming new protoplanets as tools for research and teaching are developed. These tools include problem-solving exercises or simulations of adaptive optics explanations and scientific reasoning; rubrics to evaluate the scientific reasoning simulation responses, knowledge regarding inclusive science education, and student explanations of science/engineering inquiry investigations; and a scientific reasoning curriculum. Another applied research project is forming with the design of a study regarding how to assess engineering explanations. To illustrate the mutual shaping of the cross-disciplinary, intergenerational group of educational researchers and their projects, the paper ends with a description of the professional trajectories of some of the

    The Earth Resources Observation and Science (EROS) Center is a U.S. Geological Survey (USGS) facility focused on providing science and imagery to better understand our Earth. As part of the USGS Geography Discipline, EROS contributes to the Land Remote Sensing (LRS) Program, the Geographic Analysis and Monitoring (GAM) Program, and the National Geospatial Program (NGP), as well as our Federal partners and cooperators. The work of the Center is shaped by the Earth sciences, the missions of our stakeholders, and implemented through strong program and project management and application of state-of-the-art information technologies. Fundamentally, EROS contributes to the understanding of a changing Earth through 'research to operations' activities that include developing, implementing, and operating remote sensing based terrestrial monitoring capabilities needed to address interdisciplinary science and applications objectives at all levels-both nationally and internationally. The Center's programs and projects continually strive to meet and/or exceed the changing needs of the USGS, the Department of the Interior, our Nation, and international constituents. The Center's multidisciplinary staff uses their unique expertise in remote sensing science and technologies to conduct basic and applied research, data acquisition, systems engineering, information access and management, and archive preservation to address the Nation's most critical needs. Of particular note is the role of EROS as the primary provider of Landsat data, the longest comprehensive global land Earth observation record ever collected. This report is intended to provide an overview of the scientific and engineering achievements and illustrate the range and scope of the activities and accomplishments at EROS throughout fiscal year (FY) 2009. Additional information concerning the scientific, engineering, and operational achievements can be obtained from the scientific papers and other documents published by

Each center is pursuing the basic research underlying a range of high-risk, high-return biological solutions for bioenergy applications. Advances resulting from the BRCs are providing the knowledge needed to develop new biobased products, methods, and tools that the emerging biofuel industry can use (see sidebar, Bridging the Gap from Fundamental Biology to Industrial Innovation for Bioenergy, p. 6). The DOE BRCs have developed automated, high-throughput analysis pipelines that will accelerate scientific discovery for biology-based biofuel research. The three centers, which were selected through a scientific peer-review process, are based in geographically diverse locations - the Southeast, the Midwest, and the West Coast - with partners across the nation (see U.S. map, DOE Bioenergy Research Centers and Partners, on back cover). DOE's Lawrence Berkeley National Laboratory leads the DOE Joint BioEnergy Institute (JBEI) in California; DOE's Oak Ridge National Laboratory leads the BioEnergy Science Center (BESC) in Tennessee; and the University of Wisconsin-Madison leads the Great Lakes Bioenergy Research Center (GLBRC). Each center represents a multidisciplinary partnership with expertise spanning the physical and biological sciences, including genomics, microbial and plant biology, analytical chemistry, computational biology and bioinformatics, and engineering. Institutional partners include DOE national laboratories, universities, private companies, and nonprofit organizations.

    1998-01-01

    The communication of new scientific knowledge and understanding is an integral component of science research, essential for its continued survival. Like any learning-based activity, science cannot continue without communication between and among peers so that skeptical inquiry and learning can take place. This communication provides necessary organic support to maintain the development of new knowledge and technology. However, communication beyond the peer-community is becoming equally critical for science to survive as an enterprise into the 21st century. Therefore, scientists not only have a 'noble responsibility' to advance and communicate scientific knowledge and understanding to audiences within and beyond the peer-community, but their fulfillment of this responsibility is necessary to maintain the survival of the science enterprise. Despite the critical importance of communication to the viability of science, the skills required to perform effective science communications historically have not been taught as a part of the training of scientist, and the culture of science is often averse to significant communication beyond the peer community. Thus scientists can find themselves ill equipped and uncomfortable with the requirements of their job in the new millennium.

  8. Interaction of science and diplomacy: Latin American, the United States and nuclear energy, 1945-1955

    International Nuclear Information System (INIS)

    Cabral, R.

    1986-01-01

    Nuclear programs in Argentina and Brazil can be traced to August 1945 when their scientific communities articulated responses to the atomic bombings of Japan. They culminated in attempts to develop independent nuclear programs, sharply opposed by the United States, during the nationalist governments of Juan Peron and Getulio Vargas. This dissertation, based on primary sources from the three nations, analyzes these programs and the American responses. Latin America entered the nuclear age attempting to control natural resources, to improve scientific establishments, and to appraise Latin American-United States relations. Despite some clear warnings about nuclear dangers, the new form of energy was seen as the solution to industrial problems, poverty, and outside political interference. International opposition, which may have included nuclear threats from the United States, blocked Argentina's first attempt in 1947. After 1948, Peron wanted a nuclear program for cheap energy and prestige. The qualifications of the Brazilian scientists gave more substance to their program. The program originated in August, 1945, but assumed national proportion with the government of Vargas in 1951. Lack of American cooperation forced Vargas to establish a secret program with Germany. American troops intervened taking over the German equipment already completed. The final collapse came about with Vargas' suicide in August, 1954

This program is bringing together scientists in diverse fields to understand the complex biology underlying solutions to DOE missions in energy production, environmental remediation, and climate change science. New interdisciplinary research communities are emerging, as are knowledgebases and scientific and computational resources critical to advancing large-scale, genome-based biology. To focus the most advanced biotechnology-based resources on the biological challenges of biofuel production, DOE established three Bioenergy Research Centers (BRCs) in September 2007. Each center is pursuing the basic research underlying a range of high-risk, high-return biological solutions for bioenergy applications. Advances resulting from the BRCs will provide the knowledge needed to develop new biobased products, methods, and tools that the emerging biofuel industry can use. The scientific rationale for these centers and for other fundamental genomic research critical to the biofuel industry was established at a DOE workshop involving members of the research community (see sidebar, Biofuel Research Plan, below).

    Abstract The Food and Drug Administration (FDA) regulations require sponsors of clinical investigations involving an investigational drug or device to submit an Investigational New Drug (IND) or Investigational Device Exemption (IDE) application. Strict adherence to applicable regulations is vital to the success of clinical research. Unlike most major pharmaceutical sponsors, investigator sponsors often do not fully appreciate their regulatory obligations nor have resources to ensure compliance. As a result they can place themselves and their institutions at risk. Nevertheless, investigator‐initiated clinical trials are vital to the further development of innovative drugs, biologics, and medical devices. The IND/IDE Subcommittee under the Regulatory Knowledge and Support Program at Harvard Catalyst, The Harvard Clinical and Translational Science Center worked in collaboration with Harvard and Harvard affiliated institutions to create and launch an IND/IDE Consult Service in a decentralized network of collaborating Academic Healthcare Centers (AHC). The IND/IDE Consult Service offers expertise, resources, and shared experiences to assist sponsor‐investigators and IRBs in meeting regulatory requirements for conducting and reviewing investigator‐initiated IND/IDE studies. The scope of the services provided by the Harvard Catalyst IND/IDE Consult Service are described, including the specifics of the service, lessons learned, and challenges faced, in a scalable model that builds inter‐institutional capacity.

    The Food and Drug Administration (FDA) regulations require sponsors of clinical investigations involving an investigational drug or device to submit an Investigational New Drug (IND) or Investigational Device Exemption (IDE) application. Strict adherence to applicable regulations is vital to the success of clinical research. Unlike most major pharmaceutical sponsors, investigator sponsors often do not fully appreciate their regulatory obligations nor have resources to ensure compliance. As a result they can place themselves and their institutions at risk. Nevertheless, investigator-initiated clinical trials are vital to the further development of innovative drugs, biologics, and medical devices. The IND/IDE Subcommittee under the Regulatory Knowledge and Support Program at Harvard Catalyst, The Harvard Clinical and Translational Science Center worked in collaboration with Harvard and Harvard affiliated institutions to create and launch an IND/IDE Consult Service in a decentralized network of collaborating Academic Healthcare Centers (AHC). The IND/IDE Consult Service offers expertise, resources, and shared experiences to assist sponsor-investigators and IRBs in meeting regulatory requirements for conducting and reviewing investigator-initiated IND/IDE studies. The scope of the services provided by the Harvard Catalyst IND/IDE Consult Service are described, including the specifics of the service, lessons learned, and challenges faced, in a scalable model that builds inter-institutional capacity. © 2014 Wiley Periodicals, Inc.

    IntroductionIn 2009, the U.S. Department of the Interior (DOI) Secretary Ken Salazar established a network of eight regional Climate Science Centers (CSCs) that, along with the Landscape Conservation Cooperatives (LCCs), would help define and implement the Department's climate adaptation response. The Southeast Climate Science Center (SE CSC) was established at North Carolina State University (NCSU) in Raleigh, North Carolina, in 2010, under a 5-year cooperative agreement with the U.S. Geological Survey (USGS), to identify and address the regional challenges presented by climate change and variability in the Southeastern United States. All eight regional CSC hosts, including NCSU, were selected through a competitive process.Since its opening, the focus of the SE CSC has been on working with partners in the identification and development of research-based information that can assist managers, including cultural and natural resource managers, in adapting to global change processes, such as climate and land use change, that operate at local to global scales and affect resources important to the DOI mission. The SE CSC was organized to accomplish three goals:Provide co-produced, researched based, actionable science that supports transparent global change adaptation decisions.Convene conversations among decision makers, scientists, and managers to identify key ecosystem adaptation decisions driven by climate and land use change, the values and objectives that will be used to make decisions, and the research-based information needed to assess adaptation options.Build the capacity of natural resource professionals, university faculty, and students to understand and frame natural resource adaptation decisions and develop and use research-based information to make adaptation decisions.This report provides an overview of the SE CSC and the projects developed by the SE CSC since its inception. An important goal of this report is to provide a framework for understanding the

    The Penn State Breazeale Nuclear Reactor (PSBR) at the Radiation Science and Engineering Center (RSEC) has produced radioisotopes for research and commercial purposes since 1956. With the rebirth of the radiochemistry education and research program at the RSEC, the Center stands poised to produce a variety of radioisotopes for research and industrial work that is in line with the mission of the DOE Office of Science, Office of Nuclear Physics, Isotope Development and Production Research and Application Program. The RSEC received funding from the Office of Science in 2010 to improve production techniques and develop new capabilities. Under this program, we improved our existing techniques to provide four radioisotopes (Mn-56, Br-82, Na-24, and Ar-41) to researchers and industry in a safe and efficient manner. The RSEC is also working to develop new innovative techniques to provide isotopes in short supply to researchers and others in the scientific community, specifically Cu-64 and Cu-67. Improving our existing radioisotopes production techniques and investigating new and innovative methods are two of the main initiatives of the radiochemistry research program at the RSEC.

    This study describes the development of an instrument to investigate the extent to which student-centered actions are occurring in science classrooms. The instrument was developed through the following five stages: (1) student action identification, (2) use of both national and international content experts to establish content validity, (3) refinement of the item pool based on reviewer comments, (4) pilot testing of the instrument, and (5) statistical reliability and item analysis leading to additional refinement and finalization of the instrument. In the field test, the instrument consisted of 26 items separated into four categories originally derived from student-centered instruction literature and used by the authors to sort student actions in previous research. The SACS was administered across 22 Grade 6-8 classrooms by 22 groups of observers, with a total of 67 SACS ratings completed. The finalized instrument was found to be internally consistent, with acceptable estimates from inter-rater intraclass correlation reliability coefficients at the p Observation Protocol. Based on the analyses completed, the SACS appears to be a useful instrument for inclusion in comprehensive assessment packages for illuminating the extent to which student-centered actions are occurring in science classrooms.

  18. Mexican and Mexican-American children's funds of knowledge as interventions into deficit thinking: opportunities for praxis in science education

    In this case study, I use an ethnographic-style approach to understand the funds of knowledge of immigrant families living in colonias on both sides of the US/Mexico border. I focus on how these "knowledges" and concomitant experiences impact the ways we perceive and treat immigrant students who have all too often been viewed through deficit lenses that relegate them to the lowest expectations and outcomes in the classroom. I find that Mexican and Mexican-American families hold unusually sophisticated and relevant "knowledges" to mitigate their everyday lives. In this paper, I will refer to citizens of Mexico, whether they reside in Mexico or have crossed to the United States legally or without documentation for purposes of work, as Mexican. People who have crossed the border and are living in the US as legal residents or have gained citizenship are referred to as Mexican-Americans. They live a hybrid identity that is varied and dynamic, an issue that adds to the complexity of the content and contexts of this study. These families know and use these "knowledges" on a daily basis, yet they are not recognized by teachers in the US as a starting point to affirm and support immigrant children. Instead, immigrant children are relegated to the non-gifted and lower track classes where science is taught from an abstract and non-contextual and therefore less engaged basis. The approach I outline here, based on insights from my case study, can greatly improve teachers' abilities to prepare their curricula for diversity in science education and science literacy as well as for broad expectations for student success.

  19. Sexual Orientation Differences as Deficits: Science and Stigma in the History of American Psychology.

    This article briefly describes how psychology, psychiatry, and the mental health professions (here collectively referred to as Psychology) treated sexual orientation differences as deficits for much of the 20th century, as well as some of the negative consequences that practice had for sexual minorities. The 1970s witnessed a remarkable turnaround when the American Psychiatric Association removed homosexuality from the Diagnostic and Statistical Manual of Mental Disorders and the American Psychological Association called for psychologists to work to remove the stigma historically associated with homosexuality. This history illustrates not only how cultural institutions play a central role in legitimating stigma, but also how they can recognize their own complicity in this process and work effectively to undo its harmful effects. It is argued that Psychology still has an important role to play in challenging the differences-as-deficits model in contemporary policy debates. © The Author(s) 2010.

  20. An ecological perspective of science and math academic achievement among African American students

    Using data from the National Education Longitudinal Study of 1988 (NELS:88), path analytic procedures were performed to test an ecological model of the effects of family, individual and school characteristics on the academic African American students. A distinctive study is the inclusion of school computer use in the model. The study results show that several of the variables directly or indirectly affected 12th grade academic achievement. Furthermore, most of the individual influence variables were directly related to 12 th grade achievement. Two surprising findings from this study were the insignificant effects of family income and school computer use on 12 th grade achievement. Overall, the findings support the notion that family, individual, and school characteristics are important predictors of academic success among African American students.
