    1990-12-01

    The Plasma Science Committee (PLSC) is a standing committee under the auspices of the Board on Physics and Astronomy, Commission on Physical Sciences, Mathematics, and Applications of the National Academy of Sciences - National Research Council. Plasma sciences represent a broad and diverse field. The PLSC has accepted the responsibility of monitoring the continuing development and assessing the general health of the field as whole. Although select advisory bodies have been created to address specific issues that affect plasma science, such as the Fusion Policy Advisory Committee (FPAC), the PLSC provides a focus for the plasma science community that is unique and essential. The membership of the PLSC is drawn from research laboratories in universities, industry, and government. Areas of expertise on the committee include accelerators and beams, space physics, astrophysics, computational physics and applied mathematics, fusion plasmas, fundamental experiments and theory, radiation sources, low temperature plasmas, and plasma-surface interactions. The PLSC is well prepared to respond to requests for studies on specific issues.

    1999-11-01

    Education and public outreach (EPO) continue to play an important role in how science is funded by the federal government. The plasma science community has a responsibility to share their exciting science with the American public. Bruce Alberts, president of the National Academy of Sciences, and Neal Lane, former head of NSF, are on record as strong advocates of scientists becoming more actively and effectively engaged in K-12 science education reform. In addition, research directorates of funding agencies like NASA and NSF are increasingly encouraging (and in some cases requiring) the integration of science and education and greater scientist involvement in EPO. How does plasma science and scientists fit into this broader political and social landscape? How well does the public understand our science and technology? Are there ways to effectively engage the public that provide good visibility for plasma science? These questions and more will be addressed in this talk. The Space Science Institute (SSI), a nonprofit organization in Colorado, provides national leadership in developing innovative ways to translate the activities and resources of space and earth science research into exciting and effective K-12 and museum education programs. SSI’s mission is to link its space science research enterprise with its education programs. SSI has active programs in curriculum and exhibit development and professional development for both scientists about education and for educators about science. I will share with you one exhibit project and one curriculum project whose goals are to raise public understanding of space plasmas and by extension all of plasma science.

  4. Community centrality and social science research.

    Allman, Dan

    2015-12-01

    Community centrality is a growing requirement of social science. The field's research practices are increasingly expected to conform to prescribed relationships with the people studied. Expectations about community centrality influence scholarly activities. These expectations can pressure social scientists to adhere to models of community involvement that are immediate and that include community-based co-investigators, advisory boards, and liaisons. In this context, disregarding community centrality can be interpreted as failure. This paper considers evolving norms about the centrality of community in social science. It problematises community inclusion and discusses concerns about the impact of community centrality on incremental theory development, academic integrity, freedom of speech, and the value of liberal versus communitarian knowledge. Through the application of a constructivist approach, this paper argues that social science in which community is omitted or on the periphery is not failed science, because not all social science requires a community base to make a genuine and valuable contribution. The utility of community centrality is not necessarily universal across all social science pursuits. The practices of knowing within social science disciplines may be difficult to transfer to a community. These practices of knowing require degrees of specialisation and interest that not all communities may want or have.

    The Coalition for Plasma Science (CPS) has established a plasma prize at the annual Intel International Science and Engineering Fair (ISEF). The 2006 prize was awarded for a project that investigated the correlation of GPS errors with various measures of near-earth plasma activity. The CPS is a broadly-based group of institutions and individuals whose goal is to increase the understanding of plasmas for non-technical audiences. In addition to the ISEF plasma award, CPS activities include maintaining a website, http://www.plasmacoalition.org; developing educational literature; organizing educational luncheon presentations for Members of Congress and their staffs; and responding to questions about plasmas. In addition, the CPS has begun as effort to examine the plasma content of state education standards with the goal of promoting the adoption of standards with appropriate plasma conten; e.g. are there three or four states of matter. The success of this and other activities depend on the voluntary labor of CPS members and associates. Please send an e-mail to the CPS at CPS@plasmacoalition.org for information if you would like to become involved in spreading the good word about plasmas.

    Journal of Physics D: Applied Physics published the first Plasma Roadmap in 2012 consisting of the individual perspectives of 16 leading experts in the various sub-fields of low temperature plasma science and technology. The 2017 Plasma Roadmap is the first update of a planned series of periodic updates of the Plasma Roadmap. The continuously growing interdisciplinary nature of the low temperature plasma field and its equally broad range of applications are making it increasingly difficult to identify major challenges that encompass all of the many sub-fields and applications. This intellectual diversity is ultimately a strength of the field. The current state of the art for the 19 sub-fields addressed in this roadmap demonstrates the enviable track record of the low temperature plasma field in the development of plasmas as an enabling technology for a vast range of technologies that underpin our modern society. At the same time, the many important scientific and technological challenges shared in this roadmap show that the path forward is not only scientifically rich but has the potential to make wide and far reaching contributions to many societal challenges.

    In 2007 NEPTUNE Canada will install the first stage of a regional cabled observatory (RCO) in the northeast Pacific Ocean. Stage 2 of the RCO is being developed by the US-based ORION Project Office, through the National Science Foundation's Ocean Observatory Initiative (OOI). For Stage 1, a 800km fiber-optic cable will loop out from a shore station on Vancouver Island to the Juan de Fuca volcanic spreading ridge. Two seafloor nodes are planned, one to support studies of tectonic and hydrothermal activity on the Endeavour Segment of the Juan de Fuca Ridge, and the other for investigation of a broad range of processes in Barkley Canyon, on the continental slope of Vancouver Island. Each node will provide power and Ethernet communications to instruments that comprise multi-disciplinary community science experiments. These experiments were developed through a 2-year series of workshops and a final competition. Data from all instruments will be available on-line, through the NEPTUNE data management and archive system. Investigations at the Endeavour node will focus on links between seismic activity and hydrothermal emissions and their resulting impact on hydrothermal vent organisms and regional oceanic circulation and geochemical fluxes. This area provides a number of technical challenges, including the laying of the backbone cable over a volcanic terrain, and the placement of instruments and extension cables in areas of abundant high-temperature venting. Planned instruments include broad-band seismometers, acoustic Doppler current meters, video and digital still cameras and chemical sensors. Experiments at the Barkley Canyon site will emphasis the effects of water currents passing through the canyon, and seismic activity. Combined biological and physical oceanographic instruments will monitor the interaction between sediment transport along the axis of the canyon and the bioturbation activity of the fauna.

    1991-01-01

    An overview is presented of the broad perspective of all plasma science. Detailed discussions are given of scientific opportunities in various subdisciplines of plasma science. The first subdiscipline to be discussed is the area where the contemporary applications of plasma science are the most widespread, low temperature plasma science. Opportunities for new research and technology development that have emerged as byproducts of research in magnetic and inertial fusion are then highlighted. Then follows a discussion of new opportunities in ultrafast plasma science opened up by recent developments in laser and particle beam technology. Next, research that uses smaller scale facilities is discussed, first discussing non-neutral plasmas, and then the area of basic plasma experiments. Discussions of analytic theory and computational plasma physics and of space and astrophysical plasma physics are then presented.

  11. Community science, philosophy of science, and the practice of research.

    Science.gov (United States)

    Tebes, Jacob Kraemer

    2005-06-01

    Embedded in community science are implicit theories on the nature of reality (ontology), the justification of knowledge claims (epistemology), and how knowledge is constructed (methodology). These implicit theories influence the conceptualization and practice of research, and open up or constrain its possibilities. The purpose of this paper is to make some of these theories explicit, trace their intellectual history, and propose a shift in the way research in the social and behavioral sciences, and community science in particular, is conceptualized and practiced. After describing the influence and decline of logical empiricism, the underlying philosophical framework for science for the past century, I summarize contemporary views in the philosophy of science that are alternatives to logical empiricism. These include contextualism, normative naturalism, and scientific realism, and propose that a modified version of contextualism, known as perspectivism, affords the philosophical framework for an emerging community science. I then discuss the implications of perspectivism for community science in the form of four propositions to guide the practice of research.

  13. Global learning communities: Science classrooms without walls

    Science.gov (United States)

    Kerlin, Steven C.

    The physical walls of a classroom have typically acted as the boundary of school science learning communities. The participants in these learning communities are the students and the teacher in individual classrooms. These participants contribute to scientific discourse about a specific content area under study. Scientific learning communities, on the other hand, long ago moved beyond the confines of a laboratory, meeting room or any one physical location. Scientists engage in ongoing discourse with many members of the scientific community in different locations all over the world. These same technological advances can now be used by science teachers and students to venture out of their classroom and become involved in a global learning community (GLC). The context of this study, From Local to Extreme Environments (FLEXE), is a science curriculum that attempts to expand the boundaries of the science classroom and involve students in a GLC. FLEXE participants are not limited to conversations with students and a teacher in one classroom. Students and teachers in many classrooms in multiple countries, deep-sea scientists, and university education researchers are involved in the FLEXE community. This study was framed by theories of sociocultural learning, discourse and learning communities. These theoretical research perspectives acted as lenses for the examination of communication of student participants in a GLC. Student views of their collaboration and their scientific writing were studied within a principle contrast of U.S. students in domestic or international class partnerships. A mixed methods approach was used to study the GLC established in the FLEXE program. Statistical analyses were used with "quick questions" (QQs) that follow each online session, in order to characterize students' views of the online global learning environment. Argumentation analysis was used to examine and compare how students supported their scientific claims with a number of different

    2015-11-01

    We invite you to the Town Meeting on the role of the National Science Foundation (NSF) in supporting basic and applied research in Plasma Physics in the U.S. The overarching goal of NSF is to promote the progress of science and to enable training of the next generation of scientists and engineers at US colleges and universities. In this context, the role of the NSF Physics Division in leading the nearly 20 year old NSF/DOE Partnership in Basic Plasma Science and Engineering serves as an example of the long history of NSF support for basic plasma physics research. Yet, the NSF interest in maintaining a healthy university research base in plasma sciences extends across the Foundation. A total of five NSF Divisions are participating in the most recent Partnership solicitation, and a host of other multi-disciplinary and core programs provide opportunities for scientists to perform research on applications of plasma physics to Space & Solar Physics, Astrophysics, Accelerator Science, Material Science, Plasma Medicine, and many sub-disciplines within Engineering. This Town Meeting will provide a chance to discuss the full range of relevant NSF funding opportunities, and to begin a conversation on the present and future role of NSF in stewarding basic plasma science and engineering research at US colleges and universities. We would like to particularly encourage early career scientists and graduate students to participate in this Town Meeting, though everyone is invited to join what we hope to be a lively discussion.

  17. Research Experiences in Community College Science Programs

    Beauregard, A.

    2011-12-01

    The benefits of student access to scientific research opportunities and the use of data in curriculum and student inquiry-driven approaches to teaching as effective tools in science instruction are compelling (i.e., Ledley, et al., 2008; Gawel & Greengrove, 2005; Macdonald, et al., 2005; Harnik & Ross. 2003). Unfortunately, these experiences are traditionally limited at community colleges due to heavy faculty teaching loads, a focus on teaching over research, and scarce departmental funds. Without such hands-on learning activities, instructors may find it difficult to stimulate excitement about science in their students, who are typically non-major and nontraditional. I present two different approaches for effectively incorporating research into the community college setting that each rely on partnerships with other institutions. The first of these is a more traditional approach for providing research experiences to undergraduate students, though such experiences are limited at community colleges, and involves student interns working on a research project under the supervision of a faculty member. Specifically, students participate in a water quality assessment study of two local bayous. Students work on different aspects of the project, including water sample collection, bio-assay incubation experiments, water quality sample analysis, and collection and identification of phytoplankton. Over the past four years, nine community college students, as well as two undergraduate students and four graduate students from the local four-year university have participated in this research project. Aligning student and faculty research provides community college students with the unique opportunity to participate in the process of active science and contribute to "real" scientific research. Because students are working in a local watershed, these field experiences provide a valuable "place-based" educational opportunity. The second approach links cutting-edge oceanographic

    Murphy, Nicholas A.; Huang, Yi-Min; PlasmaPy Collaboration

    2016-10-01

    In recent years, researchers in several disciplines have collaborated on community-developed open source Python packages such as Astropy, SunPy, and SpacePy. These packages provide core functionality, common frameworks for data analysis and visualization, and educational tools. We propose that our community begins the development of PlasmaPy: a new open source core Python package for plasma physics. PlasmaPy could include commonly used functions in plasma physics, easy-to-use plasma simulation codes, Grad-Shafranov solvers, eigenmode solvers, and tools to analyze both simulations and experiments. The development will include modern programming practices such as version control, embedding documentation in the code, unit tests, and avoiding premature optimization. We will describe early code development on PlasmaPy, and discuss plans moving forward. The success of PlasmaPy depends on active community involvement and a welcoming and inclusive environment, so anyone interested in joining this collaboration should contact the authors.

    26th Symposium on Plasma Science for Materials (SPSM-26) Takayuki Watanabe The 26th Symposium on Plasma Science for Materials (SPSM-26) was held in Fukuoka, Japan on September 23-24, 2013. SPSM has been held annually since 1988 under the sponsorship of The 153rd Committee on Plasma Materials Science, Japan Society for the Promotion of Science (JSPS). This symposium is one of the major activities of the Committee, which is organized by researchers in academia and industry for the purpose of advancing intersectional scientific information exchange and discussion of science and technology of plasma materials processing. Plasma processing have attracted extensive attention due to their unique advantages, and it is expected to be utilized for a number of innovative industrial applications such as synthesis of high-quality and high-performance nanomaterials. The advantages of plasmas including high chemical reactivity in accordance with required chemical reactions are beneficial for innovative processing. In recent years, plasma materials processing with reactive plasmas has been extensively employed in the fields of environmental issues and biotechnology. This conference seeks to bring different scientific communities together to create a forum for discussing the latest developments and issues. The conference provides a platform for the exploration of both fundamental topics and new applications of plasmas by the contacts between science, technology, and industry. The conference was organized in plenary lectures, invited, contributed oral presentations, and poster sessions. At this meeting, we had 142 participants from 10 countries and 104 presentations, including 11 invited presentations. This year, we arranged special topical sessions that cover Plasma Medicine and Biotechnologies, Business and Academia Cooperation, Plasma with Liquids, Plasma Processes for Nanomaterials, together with Basic, Electronics, and Thermal Plasma sessions.

    At the MIT PSFC, student and staff volunteers work together to increase the public's knowledge of fusion science and plasma technology. Seeking to generate excitement in young people about science and engineering, the PSFC hosts a number of educational outreach activities throughout the year, including Middle and High School Outreach Days. The PSFC also has an in-school science demonstration program on the theme of magnetism. The Mr. Magnet Program, headed by Mr. Paul Thomas, has been bringing lively demonstrations on magnetism into local elementary and middle schools for 15 years. This year Mr. Magnet presented the program to nearly 30,000 students at over 67 schools and other events, reaching kindergartners through college freshmen. In addition to his program on magnetism, he is offering an interactive lecture about plasma to high schools. The "Traveling Plasma Lab" encourages students to learn more about plasma science while having fun investigating plasma properties using actual laboratory techniques and equipment. Beyond the classroom, Paul Thomas has provided technical training for Boston Museum of Science staff in preparation for the opening of a Star Wars exhibit. His hands-on demos have also been filmed by the History Channel for a one-hour program about Magnetism, which aired in June 2006.

    The boundary plasma and plasma-material interactions of magnetic fusion devices are reviewed. The boundary of magnetic confinement devices, from the high-temperature, collisionless pedestal through to the surrounding surfaces and the nearby cold high-density collisional plasmas, encompasses an enormous range of plasma and material physics, and their integrated coupling. Due to fundamental limits of material response the boundary will largely define the viability of future large MFE experiments (ITER) and reactors (e.g. ARIES designs). The fusion community faces an enormous knowledge deficit in stepping from present devices, and even ITER, towards fusion devices typical of that required for efficient energy production. This deficit will be bridged by improving our fundamental science understanding of this complex interface region. The research activities and gaps are reviewed and organized to three major axes of challenges: power density, plasma duration, and material temperature. The boundary can also be considered a multi-scale system of coupled plasma and material science regulated through the non-linear interface of the sheath. Measurement, theory and modeling across these scales are reviewed, with a particular emphasis on establishing the use dimensionless parameters to understand this complex system. Proposed technology and science innovations towards solving the PMI/boundary challenges will be examined. Supported by US DOE award DE-SC00-02060 and cooperative agreement DE-FC02-99ER54512.

  8. The Future of Boundary Plasma and Material Science

    Science.gov (United States)

    Whyte, Dennis

    2012-03-01

    The boundary of magnetic confinement devices, from the pedestal through to the surrounding surfaces, encompasses an enormous range of plasma and material physics, and their integrated coupling. It is becoming clear that due to fundamental limits of plasma stability and material response the boundary will largely define the viability of an MFE reactor. However we face an enormous knowledge deficit in stepping from present devices and ITER towards a demonstration power plant. We outline the future of boundary research required to address this deficit. The boundary should be considered a multi-scale system of coupled plasma and material science regulated through the non-linear interface of the sheath. Measurement, theory and modeling across these scales are assessed. Dimensionless parameters, often used to organized core plasma transport on similarity arguments, can be extended to the boundary plasma, plasma-surface interactions and material response. This methodology suggests an intriguing way forward to prescribe and understand the boundary issues of an eventual reactor in intermediate devices. A particularly critical issue is that the physical chemistry of the material, which is mostly determined by the material temperature, has been too neglected; pointing to the requirement for boundary plasma experiments at appropriate material temperatures. Finally the boundary plasma requirements for quiescent heat exhaust and control of transient events, such as ELMs, will be examined.

    The Helicon-Cathode(HelCat) device is a medium-size linear experiment suitable for a wide range of basic plasma science experiments in areas such as electrostatic turbulence and transport, magnetic relaxation, and high power microwave (HPM)-plasma interactions. The HelCat device is based on dual plasma sources located at opposite ends of the 4 m long vacuum chamber - an RF helicon source at one end and a thermionic cathode at the other. Thirteen coils provide an axial magnetic field B >= 0.220 T that can be configured individually to give various magnetic configurations (e.g. solenoid, mirror, cusp). Additional plasma sources, such as a compact coaxial plasma gun, are also utilized in some experiments, and can be located either along the chamber for perpendicular (to the background magnetic field) plasma injection, or at one of the ends for parallel injection. Using the multiple plasma sources, a wide range of plasma parameters can be obtained. Here, the HelCat device is described in detail and some examples of results from previous and ongoing experiments are given. Additionally, examples of planned experiments and device modifications are also discussed.

Our goal is to identify facilitators and barriers to effective community-academic partnerships in American Indian and other communities, which face health disparities. We have described herein the scientific design of our National Institutes of Health (NIH)-funded study (2009-2013) and lessons learned by having a strong community partner leading the research efforts. The research team is implementing a mixed-methods study involving a survey of principal investigators (PIs) and partners across the nation and in-depth case studies of CBPR projects. We present preliminary findings on methods and measures for community-engaged research and eight lessons learned thus far regarding partnership evaluation, advisory councils, historical trust, research capacity development of community partner, advocacy, honoring each other, messaging, and funding. Study methodologies and lessons learned can help community-academic research partnerships translate research in communities.

    The radio and plasma wave (RPW) diagnostics provide a unique access to critical parameters of space plasma, in particular in planetary and satellite environments. Concerning giant planets, this has been demonstrated by major results obtained by the radio investigation on the Galileo and Cassini spacecraft, but also during the Ulysses, Voyager, and Pioneer flybys of Jupiter. Several other missions, past or in flight, demonstrate the uniqueness and relevance of RPW diagnostics to basic problems of astrophysics. The EJSM mission consists of two platforms operating in the Jupiter environment: the NASA-led Jupiter Europa Orbiter (JEO), and the ESA-led Jupiter Ganymede Orbiter (JGO). JEO and JGO will execute a choreographed exploration of the Jupiter System before settling into orbit around Europa and Ganymede, respectively. The EJSM mission architecture hence offers unique opportunities for synergistic and complementary observations that significantly enhance the overall science return of the mission. In this paper, we will first review new and unique science aspects of the Jupiter system that may benefit from different capabilities of RPW investigations onboard JGO and/or JEO: spectral and polarization information, mapping of radio sources, measurements of in situ plasma waves, currents, thermal noise, dust and nano-particle detection and characterization. We will then illustrate unique synergistic and complementary science opportunities offered by RPW investigations onboard JGO and/or JEO, both in terms of Satellite science and in terms of Magnetospheric Science.

A major question facing the S&T policy community, and indeed society at large, is therefore how science and technology can be more effectively harnessed to addressing the sustainability needs and priorities of particular communities. It is in this context that this paper...... in particular times and places, in particular practices and communities of actors. Whilst it is widely acknowledged that science, technology and innovation have a critical role to play in addressing the challenges of sustainable development it is far from evident that investment in science and technology per se...... examines whether new approaches to upstream engagement in science and technology can further knowledge channels between local communities and academia.

  15. Community Science: Creating an Alternative Place to Stand?

    Kloos, Bret

    2008-01-01

    This article comments on two emerging views of community psychology's approaches to the use of research for responding to social problems in contemporary community contexts - (a) the formation of a new field of community science, or (b) the updating of community psychology research traditions. If community science is to become established as a field related to community psychology, its proponents will need to agree upon conventions of epistemology, foci of interest, methods, and standards by which its work can be judged so that it can be distinguished from other human sciences. These articles provide early sketches for what community science might be. However, as noted in this commentary, we need to heed signs of concern about community psychology's continued relevance in public discourse regarding the analysis of and responses to social problems. While this special issue offers some promising responses to the concern of what the field can contribute, the field would be well served if we broaden our dialogue about a renewal of community psychology's commitment to social justice and the need for its perspectives in the practice of research that seeks to address community-based issues in the early 21st century.

    2010-01-01

    The Twentieth Century has been a defining period for Plasma Science and Technology. The state of ionized matter, so named by Irving Langmuir in the early part of twentieth century, has now evolved in to a multidisciplinary area with scientists and engineers from various specializations working together to exploit the unique properties of the plasma medium. There have been great improvements in the basic understanding of plasmas as a many body system bound by complex collective Coulomb interactions of charges, atoms, molecules, free radicals and photons. Simultaneously, many advanced plasma based technologies are increasingly being implemented for industrial and societal use. The emergence of the multination collaborative project International Thermonuclear Experimental Reactor (ITER) project has provided the much needed boost to the researchers working on thermonuclear fusion plasmas. In addition, the other plasma applications like MHD converters, hydrogen generation, advanced materials (synthesis, processing and surface modification), environment (waste beneficiation, air and water pollution management), nanotechnology (synthesis, deposition and etching), light production, heating etc are actively being pursued in governmental and industrial sectors. For India, plasma science and technology has traditionally remained an important area of research. It was nearly a century earlier that the Saha ionization relation pioneered the way to interpret experimental data from a vast range of near equilibrium plasmas. Today, Indian research contributions and technology demonstration capabilities encompass thermonuclear fusion devices, nonlinear plasma phenomena, plasma accelerators, beam plasma interactions, dusty and nonneutral plasmas, industrial plasmas and plasma processing of materials, nano synthesis and structuring, astrophysical and space plasmas etc. India's participation in the ITER programme is now reflected in increased interest in the research and development

    2009-11-01

    For the past five years, the Coalition for Plasma Science (CPS) has presented an award for a plasma project at the Intel International Science and Engineering Fair (ISEF). Eligible projects have ranged from grape-based plasma production in a microwave oven to observation of the effects of viscosity in a fluid model of quark-gluon plasma. Most projects have been aimed at applications, including fusion, thrusters, lighting, materials processing, and GPS improvements. However diagnostics (spectroscopy), technology (magnets), and theory (quark-gluon plasmas) have also been represented. All of the CPS award-winning projects so far have been based on experiments, with two awards going to women students and three to men. Since the award was initiated, both the number and quality of plasma projects has increased. The CPS expects this trend to continue, and looks forward to continuing its work with students who are excited about the possibilities of plasma. You too can share this excitement by judging at the 2010 fair in San Jose on May 11-12.

This year's prize was awarded for projects in simulated ball lightning and plasma thrusters. The CPS is a broadly-based group of institutions and individuals whose goal is to increase the understanding of plasmas for non-technical audiences. In addition to the ISEF plasma award, CPS activities include maintaining a website, http://www.plasmacoalition.org; developing educational literature; organizing educational luncheon presentations for Members of Congress and their staffs; and responding to questions about plasmas that are received by the CPS e-mail or toll-free number. The success of these activities depend on the voluntary labor of CPS members and associates. These volunteers include the ISEF judges, whom the APS/DPP and the IEEE/PSAC helped identify. Please send an e-mail to the CPS at CPS@plasmacoalition.org for information if you would like to become involved in spreading the good word about plasmas.

    2015-12-01

    CosmoQuest was envisioned in 2011 with a singular goal: to create a place where people of all backgrounds can learn and do science in a virtual research community. Like a brick-and-mortar center, CosmoQuest includes facilities for doing science and for educating its members through classes, seminars, and other forms of professional development. CosmoQuest is unique with its combination of public engagement in doing science—known as "citizen science"— and its diversity of learning opportunities that enable STEM education. Our suite of activities is able maximize people's ability to learn and do science, while improving scientific literacy. Since its launch on January 1, 2012, CosmoQuest has grown to become the most trafficked astronomy citizen science site on the English-language internet. It has hosted five citizen science portals supporting NASA SMD science and is the only citizen science site to have produced peer-reviewed surface science results [Robbins, et al. 2014]. CosmoQuest, however, is more than just citizen science. It is a virtual research center for the public, and for the educators who teach in classrooms and science centers. Like with with any research center, CosmoQuest's success hinges on its ability to build a committed research community, and the challenge has been creating this community without the benefit of real-world interactions. In this talk, we overview how CosmoQuest has built a virtual community through screen-to-screen interactions using a suite of technologies that must constantly evolve as the internet evolves.

  4. Doing Climate Science in Indigenous Communities

    Science.gov (United States)

    Pandya, R. E.; Bennett, B.

    2009-12-01

    Historically, the goal of broadening participation in the geosciences has been expressed and approached from the viewpoint of the majority-dominated geoscience community. The need for more students who are American Indian, Native Hawaiian, or Alaska Native is expressed in terms of the need to diversify the research community, and strategies to engage more students are often posed around the question “what can we do to get more indigenous students interested in coming to our institutions to do geosciences?” This approach can lead to neglecting indigenous ways of knowing, inadvertently prioritizes western values over traditional ones, and doesn’t necessarily honor tribal community’s desire to hold on to their talented youth. Further, while this approach has resulted in some modest success, the overall participation in geoscience by students from indigenous backgrounds remains low. Many successful programs, however, have tried an alternate approach; they begin by approaching the geosciences from the viewpoint of indigenous communities. The questions they ask center around how geosciences can advance the priorities of indigenous communities, and their approaches focus on building capacity for the geosciences within indigenous communities. Most importantly, perhaps, these efforts originate in Tribal communities themselves, and invite the geoscience research community to partner in projects that are rooted in indigenous culture and values. Finally, these programs recognize that scientific expertise is only one among many skills indigenous peoples employ in their relation with their homelands. Climate change, like all things related to the landscape, is intimately connected to the core of indigenous cultures. Thus, emerging concerns about climate change provide a venue for developing new, indigenous-centered, approaches to the persistent problem of broadening participation in the geoscience. This presentation will highlight three indigenous-led efforts in to

    The Next Generation Science Standards offer an opportunity to teach Earth and space science in ways that are closer to how scientists practice, and more relevant to students and to societal issues. However, the level of scientific community involvement required to capitalize on this opportunity is high. Building on the results of the Summit Meeting on the Implementation of the NGSS at the State Level , this presentation proposes a set of mechanisms and practices by which the NGSS Earth and space science community can support NGSS implementation at the national, state and local levels. Based on work with summit attendees, classroom teachers, informal educators and undergraduate faculty, this presentation proposes ways to build a network of practitioners with shared communication, approaches and resources. A set of mechanisms whereby the community can build relationships and share practices will be described, along with an emerging set of strategies for supporting groups as they take the first steps into implementation.

    Adams, P. E.

    2012-12-01

    Public awareness about science and science issues is often lacking in the general community; in a rural community there are even fewer options for an interested person to engage with others on science topics. One approach to address this issue is through the use of the Science Café model of citizen science at the local level. The Science Café concept, for the United States, originated in Boston (http://www.sciencecafes.org/). Science Café events are held in informal settings, such as restaurants, pubs, or coffee houses with presentations being provided by experts on the subject. The format is designed to promote discussion and questions. Fort Hays State University Science and Mathematics Institute (SMEI), located in Hays, KS, is now in its fifth year of hosting a science café in a community of 20,000 people. The program in Hays started as a grassroots effort from an area high school teacher asking SMEI to organize and support the program. Attendance at the Science Café has range from 14 to 75 people (fire code capacity!), with an average attendance of 30 people. The audience for our Science Café has been citizens, college students, high school students, and university faculty. The presenters at the Hays Science Café have ranged from scientists to engineers, high school students to hobbyists. Our topics have ranged from searching for life in the universe, wind energy, paleo-life in Kansas, climate change, honey bees, and planetary science. The program has developed a strong following in the community and has led to the formation of additional Science Café programs in Kansas. Selection of topics is based on community interest and timeliness. Publicity occurs through posters, e-mail, and social media outlets. Participants have found the sessions to be of interest and a place to learn more about the world and become informed about issues in the news. The Science Café in Hays has had a positive impact on the community.

    2007-12-01

    The core mission of the Centers for Ocean Sciences Education Excellence (COSEE) is to promote partnerships between research scientists and educators through a national network of regional and thematic centers. In addition, the COSEEs also disseminate best practices in ocean sciences education, and promote ocean sciences as a charismatic interdisciplinary vehicle for creating a more scientifically literate workforce and citizenry. Although each center is mainly funded through a peer-reviewed grant process by the National Science Foundation (NSF), the centers form a national network that fosters collaborative efforts among the centers to design and implement initiatives for the benefit of the entire network and beyond. Among these initiatives the COSEE network has contributed to the definition, promotion, and dissemination of Ocean Literacy in formal and informal learning settings. Relevant to all research scientists, an Education and Public Outreach guide for scientists is now available at www.tos.org. This guide highlights strategies for engaging scientists in Ocean Sciences Education that are often applicable in other sciences. To address the challenging issue of ocean sciences education informed by scientific research, the COSEE approach supports centers that are partnerships between research institutions, formal and informal education venues, advocacy groups, industry, and others. The COSEE Ocean Learning Communities, is a partnership between the University of Washington College of Ocean and Fishery Sciences and College of Education, the Seattle Aquarium, and a not-for-profit educational organization. The main focus of the center is to foster and create Learning Communities that cultivate contributing, and ocean sciences-literate citizens aware of the ocean's impact on daily life. The center is currently working with volunteer groups around the Northwest region that are actively involved in projects in the marine environment and to empower these diverse groups

  12. Improving Health with Science: Exploring Community-Driven Science Education in Kenya

    Science.gov (United States)

    Leak, Anne Emerson

    This study examines the role of place-based science education in fostering student-driven health interventions. While literature shows the need to connect science with students' place and community, there is limited understanding of strategies for doing so. Making such connections is important for underrepresented students who tend to perceive learning science in school as disconnected to their experiences out of school (Aikenhead, Calabrese-Barton, & Chinn, 2006). To better understand how students can learn to connect place and community with science and engineering practices in a village in Kenya, I worked with community leaders, teachers, and students to develop and study an education program (a school-based health club) with the goal of improving knowledge of health and sanitation in a Kenyan village. While students selected the health topics and problems they hoped to address through participating in the club, the topics were taught with a focus on providing opportunities for students to learn the practices of science and health applications of these practices. Students learned chemistry, physics, environmental science, and engineering to help them address the health problems they had identified in their community. Surveys, student artifacts, ethnographic field notes, and interview data from six months of field research were used to examine the following questions: (1) In what ways were learning opportunities planned for using science and engineering practices to improve community health? (2) In what ways did students apply science and engineering practices and knowledge learned from the health club in their school, homes, and community? and (3) What factors seemed to influence whether students applied or intended to apply what they learned in the health club? Drawing on place-based science education theory and community-engagement models of health, process and structural coding (Saldana, 2013) were used to determine patterns in students' applications of their

  13. Offshore Fish Community: Ecological Interactions | Science ...

    Science.gov (United States)

    The offshore (>80 m) fish community of Lake Superior is made up of predominately native species. The most prominent species are deepwater sculpin, kiyi, cisco, siscowet lake trout, burbot, and the exotic sea lamprey. Bloater and shortjaw cisco are also found in the offshore zone. Bloater is abundant in the offshore zone but appears restricted to depths shallower than 150 m (Selgeby and Hoff 1996; Stockwell et al. 2010), although it occuppied greater depths several decades ago (Dryer 1966; Peck 1977). Shortjaw is relatively rare in the offshore zone (Hoff and Todd 2004; Gorman and Hoff 2009; Gorman and Todd 2007). Lake whitefish is also known to frequent bathymetric depths >100 m (Yule et al. 2008b). In this chapter, we develop a conceptual model of the offshore food web based on data collected during 2001-2005 and on inferences from species interactions known for the nearshore fish community. We then develop a framework for examination of energy and nutrient movements within the pelagic and benthic habitats of the offshore zone and across the offshore and nearshore zones.

    The Internet offers innovative and creative means of disseminating content. But where the Internet comes into its own is in the non-linear power of community. Not only can communicators interact directly with their audience, more importantly, the audience can network with each other. This enables publishers to build communities rallied around common topics of interest. Online communities lead to exciting opportunities such as citizen science where communities crowd-source the collection or analysis of data. Skeptical Science is a case study in the development of a volunteer community that produces regular content developed within an internal review system that ensures a high level of accuracy and quality. The community also engages with the peer-reviewed literature, submitting responses to peer-reviewed papers, collecting meta-data used in other scientific research and conducting the largest ever survey of climate papers. Thus this online community both contributes to the outreach effort of climate communication and also seeks to add to the body of scientific knowledge.

    Kolker, Eugene; Stewart, Elizabeth; Ozdemir, Vural

    2012-03-01

    Twenty-first century life sciences have transformed into data-enabled (also called data-intensive, data-driven, or big data) sciences. They principally depend on data-, computation-, and instrumentation-intensive approaches to seek comprehensive understanding of complex biological processes and systems (e.g., ecosystems, complex diseases, environmental, and health challenges). Federal agencies including the National Science Foundation (NSF) have played and continue to play an exceptional leadership role by innovatively addressing the challenges of data-enabled life sciences. Yet even more is required not only to keep up with the current developments, but also to pro-actively enable future research needs. Straightforward access to data, computing, and analysis resources will enable true democratization of research competitions; thus investigators will compete based on the merits and broader impact of their ideas and approaches rather than on the scale of their institutional resources. This is the Final Report for Data-Intensive Science Workshops DISW1 and DISW2. The first NSF-funded Data Intensive Science Workshop (DISW1, Seattle, WA, September 19-20, 2010) overviewed the status of the data-enabled life sciences and identified their challenges and opportunities. This served as a baseline for the second NSF-funded DIS workshop (DISW2, Washington, DC, May 16-17, 2011). Based on the findings of DISW2 the following overarching recommendation to the NSF was proposed: establish a community alliance to be the voice and framework of the data-enabled life sciences. After this Final Report was finished, Data-Enabled Life Sciences Alliance (DELSA, www.delsall.org ) was formed to become a Digital Commons for the life sciences community.

    This study examines the relationship between informal science and indigenous innovations in local communities in which students matured. The discussion considers methods for bridging the gap that exists between parents' understanding of informal science ( Ubunifu) and what students learn in secondary schools in Kenya, Tanzania, and Uganda. In an effort to reconcile the difference between students' lived experiences and Science, Technology, Engineering, and Mathematics (STEM) taught in classrooms, this study presents an experiential iSPACES instructional model as an example of curriculum integration in science classrooms. The culmination is presentation of lessons learned from history, including Africa's unique contributions to science, theory, and indigenous innovations, in the hope that these lessons can spur the development of new instructional practices, standards, curriculum materials, professional and community development, and dialogue among nations.

    Engagement of the community through informal dialogue with researchers and physicians around health and science topics is an important avenue to build understanding and affect health and science literacy. Science Cafés are one model for this casual interchange; however the impact of this approach remains under researched. The Community Engagement Key Function of the Clinical and Translational Science Institute of Southeast Wisconsin hosted a series of Science Cafés in which topics were collaboratively decided upon by input from the community. Topics ranged from Personalized Medicine to Alzheimer's and Dementia to BioMedical Innovation. A systematic evaluation of the impact of Science Cafés on attendees' self-confidence related to five health and scientific literacy concepts showed statistically significant increases across all items (Mean differences between mean retrospective pre-scores and post-scores, one tailed, paired samples t-test, n=141, phealth and scientific literacy items was excellent (n=126, α=0.87). Thematic analysis of attendees' comments provides more nuance about positive experience and suggestions for possible improvements. The evaluation provides important evidence supporting the effectiveness of brief, casual dialogue as a way to increase the public's self-rated confidence in health and science topics. © 2014 Wiley Periodicals, Inc.

    Full Text Available Background: Community-based education (CBE is utilised by health science facultiesworldwide to provide a relevant primary care experience for students and a service tounderserved communities and, hopefully, to affect student career choices. The benefits totraining institutions and students are well documented, but it may well be that communities,too, will be able to benefit from a more balanced partnership, where they are consulted in theplanning of such training programmes.Method: An exploratory qualitative study was undertaken by three South African universitiesin the provinces of Limpopo, KwaZulu-Natal and the Western Cape. Focus group interviewswere conducted in their local languages with groups of community leaders, patients andsupervisors at community sites involved in CBE training. A thematic analysis of their viewswas undertaken with the aid of NVivo (version 9. Ethics approval was obtained from therespective universities and health care training sites.Results: Benefits to the community could be categorised into short-term and long-term benefits.Short-term benefits included improved service delivery, reduction in hospital referrals, homevisits and community orientated primary health care, improved communication with patientsand enhanced professionalism of the health care practitioner. Long-term benefits includedimproved teaching through a relationship with an academic institution and student familiaritywith the health care system. Students also became involved in community upliftment projects,thereby acting as agents of change in these communities.Conclusion: Communities can certainly benefit from well-planned CBE programmes involvinga training site ‑ community site partnership. 

  4. Community research in other contexts: learning from sustainability science.

    In health research, community based participatory research (CBPR) has seen remarkable growth as an approach that overcomes many of the ethical concerns raised by traditional approaches. A community of CBPR scholars is now sharing ideas and devising new approaches to collaborative research. Yet, this is occurring in isolation from similar efforts using different nomenclature and occurring outside of health research areas. There is much to be gained by bringing these parallel discussions together. In sustainability science, for example, scholars are struggling with the question of how stakeholders and scientists can coproduce knowledge that offers useful solutions to complex and urgent environmental problems. Like CBPR in health, sustainability science is denigrated for perceived lack of rigor because of its applied problem focus and lack of positivist approach. Approaches to knowledge creation in sustainability science involve "new" ideas such as wicked problems and agent-based modeling, which would be equally applicable to CBPR. Interestingly, sustainability research is motivated less by recognition of the corrosive effects of the inequality of power than from frustration at how limited the impact of research has been, a perspective that might be useful in CBPR, particularly in conjunction with the use of some borrowed tools of sustainability science such as wicked problem analysis and agent-based modeling. Importantly, the example of sustainability science has the potential to keep CBPR from entering into a new orthodoxy of how research should be done.

    It is popular nowadays to bring techniques from bibliometrics and scientometrics into the world of digital libraries to analyze the collaboration patterns and explore mechanisms which underlie community development. In this paper we use the DBLP data to investigate the author's scientific career and provide an in-depth exploration of some of the computer science communities. We compare them in terms of productivity, population stability and collaboration trends.Besides we use these features to compare the sets of topranked conferences with their lower ranked counterparts.

    Basis sets are one of the most important input data for computational models in the chemistry, materials, biology and other science domains that utilize computational quantum mechanics methods. Providing a shared, web accessible environment where researchers can not only download basis sets in their required format, but browse the data, contribute new basis sets, and ultimately curate and manage the data as a community will facilitate growth of this resource and encourage sharing both data and knowledge. We describe the Basis Set Exchange (BSE), a web portal that provides advanced browsing and download capabilities, facilities for contributing basis set data, and an environment that incorporates tools to foster development and interaction of communities. The BSE leverages and enables continued development of the basis set library originally assembled at the Environmental Molecular Sciences Laboratory.

    2014-01-01

    Commitment to the STEM (science, technology, engineering, math) pipeline is slowly declining despite the need for professionals in the medical field. Addressing this, the John A. Burns School of Medicine developed a summer teacher-training program with a supplemental technology-learning component to improve science teachers' knowledge and skills of Molecular Biology. Subsequently, students' skills, techniques, and application of molecular biology are impacted. Science teachers require training that will prepare them for educating future professionals and foster interest in the medical field. After participation in the program and full access to the virtual material, twelve high school science teachers completed a final written reflective statement to evaluate their experiences. Using thematic analysis, knowledge and classroom application were investigated in this study. Results were two-fold: teachers identified difference areas of gained knowledge from the teacher-training program and teachers' reporting various benefits in relation to curricula development after participating in the program. It is concluded that participation in the program and access to the virtual material will impact the science community by updating teacher knowledge and positively influencing students' experience with science.

    Unidata's mission is to provide the data services, tools, and cyberinfrastructure leadership that advance Earth system science, enhance educational opportunities, and broaden participation. The Unidata community has grown from around 250 individual participants in the early years to tens of thousands of users in over 150 countries. Today, Unidata's products and services are used on every continent and by every sector of the geoscience enterprise: universities, government agencies, private sector, and other non-governmental organizations. Certain traits and ethos are shared by and common to most successful organizations. They include a healthy organizational culture grounded by some core values and guiding principles. In that environment, there is an implicit awareness of the connection between mission of an organization, its values, and its day-to-day activities, and behaviours of a passionate staff. Distinguishing characteristics include: vigorous engagement of the community served by those organizations backed by strong and active governance, unwavering commitment to seek input and feedback from users, and trust of those users, earned over many years through consistent, dependable, and high-quality service. Meanwhile, changing data volumes and standards, new computing power, and expanding scientific questions sound continue to shape the geoscience community. These issues were the drivers for founding Unidata, a cornerstone data facility, in 1984. Advances in geoscience occur at the junction of community, science, and technology and this submission will feature lessons from Unidata's thirty year history operating at this nexus. Specifically, this presentation will feature guiding principles for the program, governance mechanisms, and approaches for balancing science and technology in a community-driven program.

  11. Reaching out and Impacting Local Communities at Professional Science Meetings

    Science.gov (United States)

    Drobnes, Emilie

    Multiple times a year scientists around the world gather to discuss and share current scientific research and results. Thousands of scientists, education specialists and others descend on a city selected by their organization's meeting planners for three to seven days only to leave again, their presence largely unfelt by the local population. Yet these varying meeting locations can provide an opportunity to involve scientists in local-scale education and outreach programs. Scientists and exhibitors can interact with the each local community, allowing them to share their excitement in science, and leave an imprint on every city visited. Taking inspiration from the American Meteorological Society's "WeatherFest", the Solar Dynamics Observatory Education and Public Outreach Team and the Rochester Institute of Technology Insight Lab have implemented a set of model programs held in conjunction with the semi-annual meetings of the American Astronomical Society. Our "Educator Reception" allows teachers to build a more concrete and personal connection with scientists and current science content which they can then impart on their students. "AstroZone" opens the conference doors to the general public and makes science accessible, exciting and fun for families, teachers, and kids - while changing their perceptions of what science is and what scientists are like. As we continue to develop our models, we are looking at ways to generalize and expand these programs to other professional organizations, providing a means for growing numbers of scientists to impact the communities that host them for their meetings.

    A small U.S. Geological Survey pilot project utilizes strategies that are successful at involving the Native community in earth science research. This work has ignited the interest of Native students in interdisciplinary geoscience studies, and gained the recognition of tribal community leaders from the conterminous United States, Alaska, and Canada. This study seeks to examine land use, climatic variability, and their related impacts on land-surface conditions in the ecologically sensitive Tsezhin Bii' region of the Navajo Nation. Work conducted by predominantly Native American researchers, includes studies of bedrock geology, surficial processes, soil and water quality, and plant ecology, as well as the history of human habitation. Community involvement that began during the proposal process, has helped to guide research, and has provided tribal members with information that they can use for land use planning and natural resource management. Work by Navajo tribal members who have become involved in research as it has progressed, includes K-12 science curriculum development, community outreach and education on environmental and geologic hazards, drought mitigation, grazing management, and impacts of climate change and land use on medicinal plants.

  13. A Key to Sharing Science: Listening to Community Needs

    Varga, M.; Phartiyal, P.; Johnson, C.

    2015-12-01

    To achieve greater effectiveness in science communication and outreach, we need to shift the paradigm from one-way communication from scientists to the (bystander) public to a two-way, listen-learn-respond exchange with concerned and knowledgeable public. Scientists need to not only know their audiences but also the needs of their audiences. Society can benefit tremendously when personal and public decisions are informed by independent and best available science. But on a variety of issues from climate to chemicals, local decision makers and public groups often struggle to know what questions to ask and to find independent information, data and analysis. Scientists also face barriers in sharing knowledge with community members. Fortunately, scientists all across the country are making such connections and forging trusted relationships with the public. The speaker will present examples of scientist-community engagement where researchers have taken the path of communicating and partnering with their local communities to address everyday issues of concern to them, from food to fracking. While such engagement efforts gain from effective communication and strategic outreach with public groups, they also has the attendant benefits of challenging scientists to consider the broader, societal implications of their work; consider how their research can serve the needs of the public; and how they can aspire to become, more than educators, learners and allies in effecting change in their communities.

    A novel aspect of the 8th International PCB Workshop at Woods Hole, MA, was the interaction between scientists and activists. While earlier workshops in this series had mentioned policy making, this Workshop focused on the problem of PCBs in schools. Focus on a problem brought an activist to give a plenary talk and facilitated a 1-day registration for other non-scientists to attend. The workshop was cohosted by the Superfund Research Programs at University of Iowa and Boston University and included active participation of each Program's Research Translation and Community Engagement Cores. A mandate of each National Institute of Environmental Health Science (NIEHS)-funded Superfund Research Program is bidirectional communication between scientists and community groups. The authors describe the events leading up to community involvement in the Workshop and the substance of the community engagement aspects of the workshop, in particular the participation by a parent-teacher group, Malibu Unites. The authors also discuss the value of such communication in terms of making important research accessible to those who are most affected by the results and poised to use it and the value of making scientists aware of the important role they play in society in addressing difficult questions that originate in community settings.

  17. The Community-Conservation Conundrum: Is Citizen Science the Answer?

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Public participation theory assumes that empowering communities leads to enduring support for new initiatives. The New Zealand Biodiversity Strategy, approved in 2000, embraces this assumption and includes goals for community involvement in resolving threats to native flora and fauna. Over the last 20 years, community-based ecological restoration groups have proliferated, with between 600 and 4000 identified. Many of these groups control invasive mammals, and often include protection of native species and species reintroductions as goals. Such activities involve the groups in “wicked” problems with uncertain biological and social outcomes, plus technical challenges for implementing and measuring results. The solution might be to develop a citizen science approach, although this requires institutional support. We conducted a web-based audit of 50 community groups participating in ecological restoration projects in northern New Zealand. We found great variation in the quality of information provided by the groups, with none identifying strategic milestones and progress towards them. We concluded that, at best, many group members are accidental scientists rather than citizen scientists. Furthermore, the way community efforts are reflected in biodiversity responses is often unclear. The situation may be improved with a new approach to data gathering, training, and analyses.

  18. Virtual school teacher's science efficacy beliefs: The effects of community of practice on science-teaching efficacy beliefs

    Science.gov (United States)

    Uzoff, Phuong Pham

    The purpose of this study was to examine how much K-12 science teachers working in a virtual school experience a community of practice and how that experience affects personal science-teaching efficacy and science-teaching outcome expectancy. The study was rooted in theoretical frameworks from Lave and Wenger's (1991) community of practice and Bandura's (1977) self-efficacy beliefs. The researcher used three surveys to examine schoolteachers' experiences of a community of practice and science-teaching efficacy beliefs. The instrument combined Mangieri's (2008) virtual teacher demographic survey, Riggs and Enochs (1990) Science-teaching efficacy Beliefs Instrument-A (STEBI-A), and Cadiz, Sawyer, and Griffith's (2009) Experienced Community of Practice (eCoP) instrument. The results showed a significant linear statistical relationship between the science teachers' experiences of community of practice and personal science-teaching efficacy. In addition, the study found that there was also a significant linear statistical relationship between teachers' community of practice experiences and science-teaching outcome expectancy. The results from this study were in line with numerous studies that have found teachers who are involved in a community of practice report higher science-teaching efficacy beliefs (Akerson, Cullen, & Hanson, 2009; Fazio, 2009; Lakshmanan, Heath, Perlmutter, & Elder, 2011; Liu, Lee, & Lin, 2010; Sinclair, Naizer, & Ledbetter, 2010). The researcher concluded that school leaders, policymakers, and researchers should increase professional learning opportunities that are grounded in social constructivist theoretical frameworks in order to increase teachers' science efficacy.

    This study explored the content, processes, and dynamics of Professional Learning Community (PLC) sessions. This study also investigated changes in preschool teachers' attitudes and beliefs toward science teaching after they participated in two different forms of PLCs including workshop and face-to-face PLC as well as workshop and online PLC. Multiple sources of data were collected for this study including participant artifacts and facilitator field notes during the PLC sessions. The participants in this study were eight teachers from NAEYC-accredited child care centers serving 3- to 5-year-old children in an urban Midwest city. All teachers participated in a workshop entitled, "Ramps and Pathways." Following the workshop, the first group engaged in face-to-face PLC sessions and the other group engaged in online PLC sessions. Qualitative data were collected through audio recordings, online archives, and open-ended surveys. The teachers' dialogue during the face-to-face PLC sessions was audiotaped, transcribed, and analyzed for emerging themes. Online archives during the online PLC sessions were collected and analyzed for emerging themes. Four main themes and 13 subthemes emanated from the face-to-face sessions, and 3 main themes and 7 subthemes emanated from the online sessions. During the face-to-face sessions, the teachers worked collaboratively by sharing their practices, supporting each other, and planning a lesson together. They also engaged in inquiry and reflection about their science teaching and child learning in a positive climate. During the online sessions, the teachers shared their thoughts and documentation and revisited their science teaching and child learning. Five themes and 15 subthemes emanated from the open-ended survey responses of face-to-face group teachers, and 3 themes and 7 subthemes emanated from the open-ended survey responses of online group teachers. Quantitative data collected in this study showed changes in teachers' attitudes and

    In this article, we investigate how mentoring relationships founded on inquiry as stance can work to emphasize the conditions that promote the development of teachers of science as inquiry. Drawing on data collected through semi-structured interviews, we have developed two narrative case studies based on the two mentoring relationships that exist between three teachers: Will, Dan, and Cathy. Will entered the teaching profession in 1966, and has acted as a mentor for Dan since he commenced teaching in 1982. Similarly, Dan has mentored Cathy since she commenced teaching in 1999. By following two generations of mentoring relationships, we have gained insights into the potential for inquiry as stance to assist the promotion of the professional development standards of the National Science Education Standards. Our data and analysis clearly point to the need for mentoring relationships to exist within larger inquiry-based communities if they are to produce rapid and sustained changes to teacher practice.

  1. Science Gateways, Scientific Workflows and Open Community Software

    Pierce, M. E.; Marru, S.

    2014-12-01

    Science gateways and scientific workflows occupy different ends of the spectrum of user-focused cyberinfrastructure. Gateways, sometimes called science portals, provide a way for enabling large numbers of users to take advantage of advanced computing resources (supercomputers, advanced storage systems, science clouds) by providing Web and desktop interfaces and supporting services. Scientific workflows, at the other end of the spectrum, support advanced usage of cyberinfrastructure that enable "power users" to undertake computational experiments that are not easily done through the usual mechanisms (managing simulations across multiple sites, for example). Despite these different target communities, gateways and workflows share many similarities and can potentially be accommodated by the same software system. For example, pipelines to process InSAR imagery sets or to datamine GPS time series data are workflows. The results and the ability to make downstream products may be made available through a gateway, and power users may want to provide their own custom pipelines. In this abstract, we discuss our efforts to build an open source software system, Apache Airavata, that can accommodate both gateway and workflow use cases. Our approach is general, and we have applied the software to problems in a number of scientific domains. In this talk, we discuss our applications to usage scenarios specific to earth science, focusing on earthquake physics examples drawn from the QuakSim.org and GeoGateway.org efforts. We also examine the role of the Apache Software Foundation's open community model as a way to build up common commmunity codes that do not depend upon a single "owner" to sustain. Pushing beyond open source software, we also see the need to provide gateways and workflow systems as cloud services. These services centralize operations, provide well-defined programming interfaces, scale elastically, and have global-scale fault tolerance. We discuss our work providing

  2. Promoting Disaster Science and Disaster Science Communities as Part of Sound Disaster Preparedness

    Science.gov (United States)

    McNutt, M. K.

    2015-12-01

    During disasters, effectively engaging the vast expertise of the academic community can help responders make timely and critical decisions. A barrier to such engagement, however, is the cultural gap between reward systems in academia and in the disaster response community. Responders often are focused on ending the emergency quickly with minimal damage. Academic scientists often need to produce peer reviewed publications to justify their use of time and money. Each community is used to speaking to different audiences, and delivering answers on their own time scales. One approach to bridge this divide is to foster a cohesive community of interdisciplinary disaster scientists: researchers who focus on crises that severely and negatively disrupt the environment or threaten human health, and are able to apply scientific methods in a timely manner to understand how to prevent, mitigate, respond to, or recover from such events. Once organized, a disaster science community could develop its own unique culture. It is well known in the disaster response community that all the preparation that takes place before an event ever occurs is what truly makes the difference in reducing response time, improving coordination, and ultimately reducing impacts. In the same vein, disaster scientists would benefit from consistently interacting with the response community. The advantage of building a community for all disasters, rather than for just one type, is that it will help researchers maintain momentum between emergencies, which may be decades or more apart. Every disaster poses similar challenges: Knowing when to speak to the press and what to say; how to get rapid, actionable peer review; how to keep proprietary industry information confidential; how to develop "no regrets" actions; and how to communicate with decision makers and the public. During the Deepwater Horizonspill, I personally worked with members of the academic research community who cared not whether they got a peer

  3. What ideas-about-science should be taught in school science? A Delphi study of the expert community

    Osborne, Jonathan; Collins, Sue; Ratcliffe, Mary; Millar, Robin; Duschl, Rick

    2003-09-01

    Recent arguments in science education have proposed that school science should pay more attention to teaching the nature of science and its social practices. However, unlike the content of science, for which there is well-established consensus, there would appear to be much less unanimity within the academic community about which ideas-about-science are essential elements that should be included in the contemporary school science curriculum. Hence, this study sought to determine empirically the extent of any consensus using a three stage Delphi questionnaire with 23 participants drawn from the communities of leading and acknowledged international experts of science educators; scientists; historians, philosophers, and sociologists of science; experts engaged in work to improve the public understanding of science; and expert science teachers. The outcome of the research was a set of nine themes encapsulating key ideas about the nature of science for which there was consensus and which were considered to be an essential component of school science curriculum. Together with extensive comments provided by the participants, these data give some measure of the existing level of agreement in the community engaged in science education and science communication about the salient features of a vulgarized account of the nature of science. Although some of the themes are already a feature of existing school science curricula, many others are not. The findings of this research, therefore, challenge (a) whether the picture of science represented in the school science curriculum is sufficiently comprehensive, and (b) whether there balance in the curriculum between teaching about the content of science and the nature of science is appropriate.

  4. Science-for-Teaching Discourse in Science Teachers' Professional Learning Communities

    Science.gov (United States)

    Lohwasser, Karin

    Professional learning communities (PLCs) provide an increasingly common structure for teachers' professional development. The effectiveness of PLCs depends on the content and quality of the participants' discourse. This dissertation was conducted to add to an understanding of the science content needed to prepare to teach science, and the discourse characteristics that create learning opportunities in teachers' PLCs. To this end, this study examined how middle school science teachers in three PLCs addressed science-for-teaching, and to what effect. Insight into discourse about content knowledge for teaching in PLCs has implications for the analysis, interpretation, and support of teachers' professional discourse, their collaborative learning, and consequently their improvement of practice. This dissertation looked closely at the hybrid space between teachers' knowledge of students, of teaching, and of science, and how this space was explored in the discourse among teachers, and between teachers and science experts. At the center of the study were observations of three 2-day PLC cycles in which participants worked together to improve the way they taught their curriculum. Two of the PLC cycles were supported, in part, by a science expert who helped the teachers explore the science they needed for teaching. The third PLC worked without such support. The following overarching questions were explored in the three articles of this dissertation: (1) What kind of science knowledge did teachers discuss in preparation for teaching? (2) How did the teachers talk about content knowledge for science teaching, and to what effect for their teaching practice? (3) How did collaborating teachers' discursive accountabilities provide opportunities for furthering the teachers' content knowledge for science teaching? The teachers' discourse during the 2-day collaboration cycles was analyzed and interpreted based on a sociocultural framework that included concepts from the practice

    Service learning is a valued component of Fundamentals of Science, a two course series required for Childhood and Special Education majors who are non-science concentrators at The College of Saint Rose. Service learning provides an opportunity for students to teach science content in the community and as a result, they begin to recognize the importance of science in the elementary classroom. A Day in the Life of the Hudson River and Project Learning Tree® (PLT) are two service learning opportunities in which the students participate. A Day in the Life of the Hudson River, an annual event sponsored by the New York State Department of Environmental Conservation Hudson River Estuary Program and Lamont-Doherty Earth Observatory, provides students with an opportunity to collect scientific data in the Hudson River. The undergraduate students partner with local K-6 classrooms and lead the collection of scientific data (chlorophyll, sediment cores, water quality) to create a snapshot of the river. The collected data are shared with the larger community and may be used by the K-6 teachers in science-based, multidiscipline lessons. Some of the findings contribute to ongoing research at Lamont-Doherty Earth Observatory. Project Learning Tree® is an environmental education program developed by the American Forest Foundation. This past year, undergraduate students participating in Project Learning Tree® were trained in a curriculum aligned with state and national science standards. In conjunction with Earth Day, the students planted trees and conducted the PLT activities in seven local schools. At the end of the service learning activity, the students wrote a reflection which provided a description of their project and indicated the connection it had with the content/skills learned in the classroom. The students also described the impact the activity had on their own learning Service learning in the pre-service teacher classroom promotes science literacy at all levels of

    In this letter, we present results from multispectroscopic analysis of protein films, after exposure to a peculiar plasma source, i.e., the capillary plasma jet. This plasma source is able to generate very small pulsed plasma volumes, in kilohertz range, with characteristic dimensions smaller than 1 mm. This leads to specific microscale generation and transport of all plasma species. Plasma diagnosis was realized using general electrical and optical methods. Depending on power level and exposure duration, this miniature plasma jet can induce controllable modifications to soft matter targets. Detailed discussions on protein film oxidation and chemical etching are supported by results from absorption, X-ray photoelectron spectroscopy, and microscopy techniques. Further exploitation of principles presented here may consolidate research interests involving plasmas in biotechnologies and plasma medicine, especially in patterning technologies, modified biomolecule arrays, and local chemical functionalization.

The imperative is to translate the combination of the rapid advances in super-computing power together with the emergence of effective new algorithms and computational methodologies to help enable corresponding increases in the physics fidelity and the performance of the scientific codes used to model complex physical systems. If properly validated against experimental measurements and verified with mathematical tests and computational benchmarks, these codes can provide more reliable predictive capability for the behavior of complex systems, including fusion energy relevant high temperature plasmas. The magnetic fusion energy research community has made excellent progress in developing advanced codes for which computer run-time and problem size scale very well with the number of processors on massively parallel supercomputers. A good example is the effective usage of the full power of modern leadership class computational platforms from the terascale to the petascale and beyond to produce nonlinear particle-in-cell simulations which have accelerated progress in understanding the nature of plasma turbulence in magnetically-confined high temperature plasmas. Illustrative results provide great encouragement for being able to include increasingly realistic dynamics in extreme-scale computing campaigns to enable predictive simulations with unprecedented physics fidelity. Some illustrative examples will be presented of the algorithmic progress from the magnetic fusion energy sciences area in dealing with low memory per core extreme scale computing challenges for the current top 3 supercomputers worldwide. These include advanced CPU systems (such as the IBM-Blue-Gene-Q system and the Fujitsu K Machine) as well as the GPU-CPU hybrid system (Titan).

  9. Schooling girls in a rural community: An examination of female science identity and science career choices

    Fowler, Melisa Diane Creasy

    There is a gap in existence between the number of males and females entering science careers. Research has begun to focus largely on how identity impacts the selection of such careers. While much research has been done to examine the factors that impact student identity, little work has been done to examine what happens to female students who have been successful in science in a rural K-12 school once they leave high school and enter the world of academia. Thus, this study examined the following questions: (1) How do three recent female high school graduates from rural K-12 high schools narrate their identity? (2) How do the females narrate their experiences in a rural community and high school in relation to their science identity? (3) What do the participants describe as influencing their academic and career choices as they transition into the life of a college student? This study involved three female participants from a small rural community in a southeastern state. Each female has lived their entire life in the community and has attended only one K-12 school. All three females ranked in the top ten of their senior class and excelled in their science coursework. Additionally, each female elected to attend college locally and to live at home. The study utilized the qualitative methodology of interpretive biography. The researcher used a guided interview protocol with participants which served as the basis for the creation of their narrative biographies. The biographies were then analyzed for emergent themes. Sociocultural theory, identity theory, and critical feminism provided the theoretical frameworks utilized in data analysis. Findings from this study suggested that there were many differing factors influencing the science identity and career choices of the females under study. However, the most salient factor impacting their choices was their desire to remain in their hometown. Directions for future research suggestions involve exploring female students who

    Forbes, Anne; Skamp, Keith

    2016-02-01

    MyScience is a primary science education initiative in which being in a community of practice is integral to the learning process. In this initiative, stakeholder groups—primary teachers, primary students and mentors—interact around the `domain' of `investigating scientifically'. This paper builds on three earlier publications and interprets the findings of the views of four secondary science teachers and five year 9 secondary science students who were first-timer participants—as mentors—in MyScience. Perceptions of these mentors' interactions with primary students were analysed using attributes associated with both `communities of practice' and the `nature of science'. Findings reveal that participation in MyScience changed secondary science teachers' views and practices about how to approach the teaching of science in secondary school and fostered primary-secondary links. Year 9 students positively changed their views about secondary school science and confidence in science through participation as mentors. Implications for secondary science teaching and learning through participation in primary school community of science practice settings are discussed.

  12. Value-sensitive clinical accompaniment in community nursing science

    2010-03-01

    Full Text Available Clinical community health facilities where undergraduate students are placed for their practical work in community nursing science are dynamic and have undergone major transformation over the past few years. In the clinical field, community nurses and undergraduate students are representative of the different races and language and ethnic groups in the South African population, with each group espousing different value systems. Both parties – students and community nurses – report that, due to these differences, value conflicts are experienced during clinical accompaniment and that this has negative effects on clinical learning in community nursing science.

    The goal of this study was to explore and describe the experiences of students with regard to value-sensitive clinical accompaniment in the community nursing environment. An exploratory, descriptive and contextual design was used. Interactions between community nurses and students during clinical accompaniment were explored for value sensitivity by means of video recordings,participant observation and focus group interviews. Data were collected by means of video recordings, participant observation and focus group interviews. The data were analysed and coded by the researcher and the external coder, using an inductive descriptive method to identify important segments of the regularity of behaviour. The focus group interviews were transcribed, analysed and coded by the researcher and the external coder, using Tesch’s steps of analysis (Creswell 1994:155–156.Lincoln and Guba’s criteria (1985:290 for trustworthiness were applied to the study.

    The general findings indicate that clinical accompaniment in community nursing is not value sensitive and, as a result, guidelines for value-sensitive clinical accompaniment need to be developed for undergraduate students in the community nursing environment. The following values (values for which guidelines need to be developed were

  13. Student questions in urban middle school science communities of practice

    Science.gov (United States)

    Groome, Meghan

    This dissertation examines student questions within three Communities of Practice (CoP), all urban middle school science environments. The study analyzed student questions from a sociocultural perspective and used ethnographic research techniques to detail how the CoP's shaped questions in the classroom. In the first study, two case study girls attempted to navigate questioning events that required them to negotiation participation. Their access to participation was blocked by participation frameworks that elevated some students as "gatekeepers" while suppressing the participation of others. The next two studies detail the introduction of written questioning opportunities, one into a public middle school classroom and the other into an informal classroom. In both studies, students responded to the interventions differently, most notable the adoption of the opportunity by female students who do not participate orally. Dissertation-wide findings indicate all students were able to ask questions, but varied in level of cognitive complexity, and the diagnostic interventions were able to identify students who were not known to be "target students", students who asked a high number of questions and were considered "interested in science". Some students' roles were as "gatekeepers" to participation of their peers. Two out of three teachers in the studies reported major shifts in their teaching practice due to the focus on questions and the methods used here have been found to be effective in producing educational research as well as supporting high-need classrooms in prior research. In conclusion, these studies indicate that social factors, including participation frameworks, gender dynamics, and the availability of alternative participation methods, play an important role in how students ask science-related questions. It is recommended that researchers continue to examine social factors that reduce student questions and modify their teaching strategies to facilitate

  20. ESA's Support To Science Element (STSE): A New Opportunity for the Science Community

    Science.gov (United States)

    Fernández Prieto, D.; Herland, E.-A.

    2009-04-01

    In 1998, the document ESA SP-1227: "The Science and Research Elements of ESA's Living Planet Programme", laid out the research objectives for the scientific component of the Living Planet Program. These were formulated around four themes: Earth Interior, Physical Climate, Geosphere/Biosphere and Atmosphere & Marine Environment: Anthropogenic Impact. These themes encompassed the full scope of Earth Science. Although no specific area of Earth Science was prioritised, the document emphasised the need to move towards an integrated Earth System Model, where the role of internationally coordinated scientific programmes and coordination with national programmes and other agencies and organisations were recognised as being a key aspect of the science strategy. In 2006, the EO Science Strategy was updated (ESA/PB-EO(2006)89) under the auspices of the ESA's Earth Science Advisory Committee (ESAC) in wide consultation with the scientific community. The resulting document: "The Changing Earth - New Scientific Challenges for ESA's Living Planet Programme" (ESA/SP-1304) outlines the new scientific direction for the future progress of the ESA Living Planet Programme. In particular, the document set out the 25 major challenges for our understanding of the Earth System with especial focus on those areas of knowledge where satellite data may make a major contribution. Achieving those challenges will require a large international effort involving, novel observation, enhanced data sets, improved models and coordinated research. ESA is contributing to those efforts through its missions (e.g., the ERS1 and 2, ENVISAT, the Meteorological satellites and the coming Earth Explorers and Sentinel series) and exploitation programs. However, in order to further reinforce the ESA support to the scientific community, a dedicated element of the Envelop program was launched in 2008, the Support To Science Element (STSE). STSE aims at providing "scientific support for both future and on

    In the scope of this study, pre-service science teachers (PSST) developed and carried out science demonstrations with everyday materials for elementary school students as a community service activity. 17 PSST enrolled in the community services practices course at Kocaeli University comprised the sample of the present study. Community service practices aim to develop consciousness of social responsibility and professional skills, as well as to gain awareness of social and community problems and find solutions for pre-service teachers. With this aim, each PSST developed five science demonstration activities and their brochures during a semester. At the end of the semester, a total of 85 demonstrations were carried out at public elementary schools, which are especially located in socioeconomically poor districts of Kocaeli, Turkey. In the present case study, the effect of developing and carrying out science demonstrations for elementary school students on six of the PSST' teaching practices on density and buoyancy concept was investigated. 30-minute interviews conducted with each PSST, videos recorded during their demonstration performances, brochures they prepared for their demonstration activities, and reflection papers were used as data collection tools of the study. The results showed that community service practices with science demonstrations had positive effects on PSST' science content knowledge and pedagogical content knowledge.

  3. Getting the big picture in community science: methods that capture context.

    Community science has a rich tradition of using theories and research designs that are consistent with its core value of contextualism. However, a survey of empirical articles published in the American Journal of Community Psychology shows that community scientists utilize a narrow range of statistical tools that are not well suited to assess contextual data. Multilevel modeling, geographic information systems (GIS), social network analysis, and cluster analysis are recommended as useful tools to address contextual questions in community science. An argument for increased methodological consilience is presented, where community scientists are encouraged to adopt statistical methodology that is capable of modeling a greater proportion of the data than is typical with traditional methods.

    In medicine, cold atmospheric plasma (CAP) for the medical treatment is a new field in plasma application, called plasma medicine. CAP contains mix of excited atoms and molecules, UV photons, charged particles as well as reactive oxygen species (ROS) and reactive nitrogen species (RNS). Typical species in air-CAPs are O3, OH, NxOx, and HNOx. The current developments in this field have fuelled the hope that CAP could be an interesting new therapeutic approach in the treatment of cancer. CAP apparently demonstrated effect on cancer cell apoptosis which did not induce cell necrosis or disruption. Moreover, CAP seemed to be selective for cancer cells since it was more effective in tumor cells than in normal non-neoplastic cells. In bioscience, dentistry and veterinary medicine : Since CAP, is delivered at room temperature, which results in less damaging effects on living tissue, while still has the efficiency in disinfection and sterilization. Recent studies proved that it is able to inactivate gram-negative and gram-positive bacteria, fungi, virus, spore, various parasites, and foreign organisms or pathogens without harming tissue. Moreover, cold plasma has been used effectively in medical field such as dental use, inducing apoptosis of malignant cells, stopping bleeding, promoting wound healing and tissue regeneration. Sericin hydrolysates, originating from silkworm is found support cell proliferation, expand cell adhesion and increase cell yield. The covalent linkage between a bioactive protein molecule and polystyrene dish surface via a carbon intermediate layer can slow down the release rate of protein compound into the phosphate buffer saline (PBS) solution. We found that a-C films and a-C:N2 films show good attachment of human bone marrow-derived mesenchymal stem cells (hBM-MSCs). All of carbon modified-Polystyrene(PS) dishes revealed the less release rate of sericin molecules into PBS solution than PS control.

  8. Science discourse in a middle-grade classroom attempting learning community-centered science instruction

    Science.gov (United States)

    Templin, Mark Arnold

    This dissertation focuses on the development of students' scientific literacy discourse in a middle grade science classroom as the teacher attempted to establish a learning community. Instructional design features included a change in teacher and students' roles such that authority over many classroom decisions was shared and students were encouraged to design their own investigations within the context of extended learning projects. The study followed the progress of two groups of four students, representing diversity in academic performance, gender, and ethnicity, over the course of four months. Target group discourse was recorded once every other school day and then transcribed. Accompanying field notes were written. Classroom artifacts, including a complete set of daily lesson plans, instructional materials, and student products, were collected. The interpretive framework, which highlighted different discourse practices and the instructional moves that supported them, evolved during data analysis as it was repeatedly tried out against the empirical materials through stages of data reduction, display, conclusion drawing, and verification. Analysis of the teacher's practice indicated that he initiated and maintained a classroom learning community by encouraging students to (a) think about their thinking by responding to questions that promoted such reflection; (b) share their reflections and other written products with each other and revise them through peer review; (c) decide for themselves which science content was relevant to their investigations; (d) share problem solving strategies; and (e) debate the meaning of terms so that a common understanding of science concepts could be developed. The teacher modeled and asked questions to promote these reflective and collaborative practices, successively withdrawing his active involvement in group dialogue as the term progressed. Analysis of students' discourse indicated that students increasingly developed

    This week, CERN is launching the CERN Global Network, which responds to a real need for us to keep in touch, to share our knowledge and expertise, and to build on the fantastic resource of the CERN community broadly defined. Here at CERN, we pride ourselves on the cross fertilization of ideas that occurs when people from around the world come together for a common goal. The Network extends that to our alumni and to our partners in academia, commerce and industry, allowing expertise to be shared among all its members. The CERN Global Network is open to anyone who works or has worked at or with CERN at any time. You don’t get much more inclusive than that. In an increasingly competitive world, knowledge transfer is vitally important for an organization like CERN. The primary outcome of our basic science is knowledge, but what use is knowledge if it’s confined to a select few? The people who drew up the CERN Convention over half a century ago saw the importance of transferring knowledge...

    In today's pedagogy, "STEM" is the four letter word and "STEAM" is the next big thing. How do we as professors translate our passion for our discipline and our research into practical, yet rigorous and applied, learning experiences for students? Foundation courses (e.g., 100 level) often have a mixture of majors and non-majors for any given discipline, thus confounding student engagement. Experiential learning provides students with opportunities to apply theory with application. In any given course, a suite of methods may need to be employed to attain the highest level of engagement. Northern Virginia Community College is a two-year institution with a strong commitment to the sciences. In this presentation, a variety of methods for student engagement will be discussed including: in-class assignments, modules in the laboratory as well as modules involving the campus, independent research experiences, and activities linking students with professionals in the area. Within the context of these methods, there will also be discussions on expectations, limitations, and successes as well as failures.

    2014-01-01

    In this paper we maintain that 21st century science is, fundamentally, a relational process in which knowledge is produced (or co-produced) through transactions among researchers or among researchers and public stakeholders. We offer an expanded perspective on the practice of 21st century science, the production of scientific knowledge, and what community psychology can contribute to these developments. We argue that: 1) trends in science show that research is increasingly being conducted in teams; 2) scientific teams, such as transdisciplinary teams of researchers or of researchers collaborating with various public stakeholders, are better able to address complex challenges; 3) transdisciplinary scientific teams are part of the larger, 21st century transformation in science; 4) the concept of heterarchy is a heuristic for team science aligned with this transformation; 5) a contemporary philosophy of science known as perspectivism provides an essential foundation to advance 21st century science; and 6) community psychology, through its core principles and practice competencies, offers theoretical and practical expertise for advancing team science and the transformation in science currently underway. We discuss the implications of these points and illustrate them briefly with two examples of transdisciplinary team science from our own work. We conclude that a new narrative is emerging for science in the 21st century that draws on interpersonal transactions in teams, and active engagement by researchers with the public to address critical accountabilities. Because of its core organizing principles and unique blend of expertise on the intersection of research and practice, community psychologists are extraordinarily well-prepared to help advance these developments, and thus have much to offer 21st century science.

    Finkelstein, Noah D.; Mayhew, Laurel

    2008-10-01

    Research in physics education has demonstrated new tools and models for improving the understanding and engagement of traditional college students [1]. Building on this base, the research community has bridged the gap from college to pre-college education, even elementary school [2]. However, little work has been done to engage students in out-of-school settings, particularly for those students from populations under-represented in the sciences. We present a theoretically-grounded model of university-community partnership [3] that engages university students and children in a collective enterprise that has the potential to improve the participation and education of all. We document the impact of these programs on: university participants who learn about education, the community and even some science; children in the community who learn about science, the nature of science and develop their identities and attitudes towards science; and, shifts in institutional practice which may allow these programs to be sustained, or not.

  15. What do you see? A case study of community college science pedagogy

    Science.gov (United States)

    Calhoun, Chantae M.

    Community colleges educate almost half of all American undergraduates. These students include but are not limited to under-prepared high school graduates, and individuals who are working full-time while attending school, as well as students of diverse cultural, socioeconomic, and ethnic backgrounds. With such a diverse student population, science educators may find it difficult to teach science, especially since the language of science is exceptional and contains some inner hierarchy that most other disciplines do not (Osborne, 2002). This qualitative case study examined a community college science faculty member notion's learning to use visual illustrations in science instruction through a collaborative professional development approach. Through this study, insights were gained on how to implement relevant science pedagogy at this community college. Narratives are used to tell the story of a community college science instructor's experience using visual illustrations through science concepts (e.g. cell structure, cellular transport, and metabolism) taught. Narratives reflect the science instructor's story leading to further studies in multiliteracies, professional development, and student perception of visual images in community college setting.

    The U. S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has an energetic science education program and outreach effort. This overview describes the components of the programs and evaluates the changes that have occurred in this effort during the last several years. Efforts have been expanded to reach more students, as well as the public in general. The primary goal is to inform the public regarding the fusion and plasma research at PPPL and to excite students so that they can appreciate science and technology. A student's interest in science can be raised by tours, summer research experiences, in-classroom presentations, plasma expos, teacher workshops and web-based materials. The ultimate result of this effort is a better-informed public, as well as an increase in the number of women and minorities who choose science as a vocation. Measuring the results is difficult, but current metrics are reviewed. The science education and outreach programs are supported by a de dicated core group of individuals and supplemented by other members of the PPPL staff and consultants who perform various outreach and educational activities.

    This research attempted to understand the experiences of a cohort of informal and formal science educators and informal science institution (ISI) community representatives during and after completion of a pilot graduate certificate program. Informal science educators (ISEs) find limited opportunities for professional development and support which influence their contributions to America's science literacy and school science education. This emergent design nested case study described how an innovative program provided professional development and enabled growth in participants' abilities to contribute to science literacy. Data were collected through interviews, participant observations, and class artifacts. The program by design and constituency was the overarching entity that accounted for members' experiences. Three principal aspects of the ISI certificate program and cohort which influenced perceptions and reported positive outcomes were (1) the cohort's composition and their collaborative activities which established a vigorous community of practice and fostered community building, mentoring, and networking, (2) long term program design and implementation which promoted experiential learning in a generative classroom, and (3) ability of some members who were able to be independent or autonomous learners to embrace science education reform strategies for greater self-efficacy and career advancement. This research extends the limited literature base for professional development of informal science educators and may benefit informal science institutions, informal and formal science educators, science education reform efforts, and public education and science-technology-society understanding. The study may raise awareness of the need to establish more professional development opportunities for ISEs and to fund professional development. Further, recognizing and appreciating informal science educators as a diverse committed community of professionals who positively

    Eisenhart, Margaret

    2008-04-01

    What are the effects of globalization and how are these manifested in local communities and in the learning of science there? These questions are unpacked within one local community in the United States, a place called "Uptown" where I examine the educational opportunities and pathways in science that are available for low-income Black American girls. The data comes from eight years of work both as an after-school science education program director and researcher in Uptown. The results suggest that globalization is taking hold, both in the social and economic circumstances of the community and in the everyday lives of the girls who live there. Further, there is possible evidence of globalization in the micro-dynamics of the after-school program. Yet opportunities for science education that could prepare the girls and their community for a globalizing world lag far behind.

  2. Professional Learning Communities (PLCs) as a Means for School-Based Science Curriculum Change

    Browne, Christi L.

    The challenge of school-based science curriculum change and educational reform is often presented to science teachers and departments who are not necessarily prepared for the complexity of considerations that change movements require. The development of a Professional Learning Community (PLC) focused on a science department's curriculum change efforts, may provide the necessary tools to foster sustainable school-based curriculum science changes. This research presents a case study of an evolving science department PLC consisting of 10 middle school science teachers from the same middle school and their efforts of school-based science curriculum change. A transformative mixed model case study with qualitative data and deepened by quantitative analysis, was chosen to guide the investigation. Collected data worked to document the essential developmental steps, the occurrence and frequency of the five essential dimensions of successful PLCs, and the influences the science department PLC had on the middle school science department's progression through school-based science curriculum change, and the barriers, struggles and inhibiting actions of the science department PLC. Findings indicated that a science department PLC was unique in that it allowed for a focal science departmental lens of science curriculum change to be applied to the structure and function of the PLC and therefore the process, proceedings, and results were directly aligned to and driven by the science department. The science PLC, while logically difficult to set-up and maintain, became a professional science forum where the middle school science teachers were exposed to new science teaching and learning knowledge, explored new science standards, discussed effects on student science learning, designed and critically analyzed science curriculum change application. Conclusions resulted in the science department PLC as an identified tool providing the ability for science departmental actions to lead to

    OAK B188 Plasma Colloquium Travel Grant Program. The purpose of the Travel Grant Program is to increase the awareness of plasma research. The new results and techniques of plasma research in fusion plasmas, plasma processing space plasmas, basic plasma science, etc, have broad applicability throughout science. The benefits of these results are limited by the relatively low awareness and appreciation of plasma research in the larger scientific community. Whereas spontaneous interactions between plasma scientists and other scientists are useful, a focused effort in education and outreach to other scientists is efficient and is needed. The academic scientific community is the initial focus of this effort, since that permits access to a broad cross-section of scientists and future scientists including undergraduates, graduate students, faculty, and research staff.

  4. The science-policy interface: Perceptions and strategies of the Iberian 'new water culture' expert community

    Directory of Open Access Journals (Sweden)

    Jeanie J. Bukowski

    2017-02-01

    Full Text Available There is a normative consensus that science should contribute to decision-making in environmental policy, given that science provides a means of understanding natural systems, human impacts upon them, and the consequences of those impacts for human systems. Despite this general agreement, however, the means through which science is transmitted into policy is contested. This paper envisions several of the competing characterisations of the science-policy interface as a continuum with the endpoints of 'fortress science' and 'co-production', and applies this continuum in an empirical analysis of the transboundary expert community promoting a 'new water culture' on the Iberian Peninsula. In engaging directly with members of this community, the paper finds that these characterisations are better seen as strategies among which scientists and their communities may choose and over which they may disagree. These trade-offs and disagreements in turn have implications for policy impact.

    The aim of this review is to clarify the importance of surface modifications induced in biomaterials for hernia-repair application. Starting from the pioneering experiences involving proto-materials as ancient prosthesis, a historical excursus between the biomaterials used in hernioplasty was realized. Subsequently, after the revolutionary discovery of stereoregular polymerization followed by the PP application in the biomedical field performed by the surgeon F. Usher, a comparative study on different hernia-repair meshes available was realized in order to better understand all the outstanding problems and possible future developments. Furthermore, since many unsolved problems on prosthetic devices implantation are linked to phenomena occurring at the interface between the biomaterials surface and the body fluids, the importance of surface science in hernioplasty was highlighted and case studies of new surface-modified generations of prosthesis presented. The results discussed in the following evidence how the surface study are becoming increasingly important for a proper knowledge of issues related to the interaction between the living matter and the artificial prostheses.

    Professional Learning Communities (PLCs) are frequently being used as a vehicle to transform science education. This study explored elementary teachers' perceptions about the impact of participating in a science PLC on their own professional development. With the use of The Science Professional Learning Communities Survey and a semi-structured interview protocol, elementary teachers' perceptions of the goals of science PLCs, the constraints and benefits of participation in PLCs, and reported differences in the impact of PLC participation on novice and experienced teachers were examined. Sixty-five elementary teachers who participated in a science PLC were surveyed about their experiences, and a subsample of 16 teachers was interviewed. Results showed that most of the teachers reported their science PLC emphasized sharing ideas with other teachers as well as working to improve students' science standardized test scores. Teachers noted that the PLCs had impacted their science assessment practices as well as their lesson planning. However, a majority of the participants reported a differential impact of PLCs depending on a teacher's level of experience. PLCs were reported as being more beneficial to new teachers than experienced teachers. The interview results demonstrated that there were often competing goals and in some cases a loss of autonomy in planning science lessons. A significant concern was the impact of problematic interpersonal relationships and communication styles on the group functioning. The role of the PLC in addressing issues related to obtaining science resources and enhancing science content knowledge for elementary science teachers is discussed.

    Health Extension Regional Officers (HEROs) through the University of New Mexico Health Sciences Center (UNMHSC) help to facilitate university-community engagement throughout New Mexico. HEROs, based in communities across the state, link priority community health needs with university resources in education, service, and research. Researchers' studies are usually aligned with federal funding priorities rather than with health priorities expressed by communities. To help overcome this misalignment, the UNM Clinical and Translational Science Center (CTSC) provides partial funding for HEROs to bridge the divide between research priorities of UNMHSC and health priorities of the state's communities. A bidirectional partnership between HEROs and CTSC researchers was established, which led to: 1) increased community engaged studies through the CTSC, 2) the HERO model itself as a subject of research, 3) a HERO-driven increase in local capacity in scholarship and grant writing, and 4) development of training modules for investigators and community stakeholders on community-engaged research. As a result, 5 grants were submitted, 4 of which were funded, totaling $7,409,002.00, and 3 research articles were published. Health extension can serve as a university-funded, community-based bridge between community health needs and Clinical and Translational Science Award (CTSA) research capacity, opening avenues for translational research. © Copyright 2017 by the American Board of Family Medicine.

    The FP7-SPACE project IMPEx (http://impex-fp7.oeaw.ac.at/) was established to provide a web-based infrastructure to facilitate the inter-comparison of spacecraft in-situ measurements and computational models in the fields of planetary plasma science. Within this project several observational (CDAWeb, AMDA, CLWeb), as well as numerical simulation (FMI, LATMOS, SINP) databases provide datasets, which can be combined for further joint analysis and scientific investigation. The major goal of this project consists in providing an environment for the connection and joint operation of the different types of numerical and observational data sources in order to validate numerical simulations with spacecraft observations and vice versa. As an important milestone of IMPEx a common metadata standard was developed for the description of the currently integrated simulation models and the archived datasets. This standard is based on the SPASE data model (DM), which originates from the Heliospheric physics community. This DM was developed for the description of observational data, and that is why it was chosen as a basis within the scope of IMPEx. A considerable part of the project effort is dedicated to the development of standardized (web service-) interfaces and protocols using the SPASE DM as an elaborated IMPEx DM for the communication between the different tools and databases of the IMPEx research infrastructure. For the visualization and analysis of the archived datasets available within IMPEx and beyond, several tools (AMDA, 3DView, ClWeb) were upgraded to be able to work with the newly developed metadata standards and protocols. A practical example will be presented to demonstrate the capabilities and potentials of the achievements of IMPEx by using these tools. Furthermore the IMPEx DM has by now also been successfully applied outside the project's core infrastructure: A prototype for UCLA MHD description can be seen at LatHyS. Besides that IRAP is currently working on a

    The design and performance optimization of particle accelerators are essential for the success of the DOE scientific program in the next decade. Particle accelerators are very complex systems whose accurate description involves a large number of degrees of freedom and requires the inclusion of many physics processes. Building on the success of the SciDAC-1 Accelerator Science and Technology project, the SciDAC-2 Community Petascale Project for Accelerator Science and Simulation (ComPASS) is developing a comprehensive set of interoperable components for beam dynamics, electromagnetics, electron cooling, and laser/plasma acceleration modelling. ComPASS is providing accelerator scientists the tools required to enable the necessary accelerator simulation paradigm shift from high-fidelity single physics process modeling (covered under SciDAC1) to high-fidelity multiphysics modeling. Our computational frameworks have been used to model the behavior of a large number of accelerators and accelerator R&D experiments, assisting both their design and performance optimization. As parallel computational applications, the ComPASS codes have been shown to make effective use of thousands of processors. ComPASS is in the first year of executing its plan to develop the next-generation HPC accelerator modeling tools. ComPASS aims to develop an integrated simulation environment that will utilize existing and new accelerator physics modules with petascale capabilities, by employing modern computing and solver technologies. The ComPASS vision is to deliver to accelerator scientists a virtual accelerator and virtual prototyping modeling environment, with the necessary multiphysics, multiscale capabilities. The plan for this development includes delivering accelerator modeling applications appropriate for each stage of the ComPASS software evolution. Such applications are already being used to address challenging problems in accelerator design and optimization. The ComPASS organization

    2011-03-01

    Full Text Available In an effort to increase science exposure for pre-college (K-12 students and as part of the science education reform agenda, many biomedical research institutions have established university-community partnerships. Typically, these science outreach programs consist of pre-structured, generic exposure for students, with little community engagement. However, the use of a medium that is accessible to both teachers and scientists, electronic web-based matchmaking (E-matching provides an opportunity for tailored outreach utilizing a community-based participatory approach (CBPA, which involves all stakeholders in the planning and implementation of the science outreach based on the interests of teachers/students and scientists. E-matching is a timely and urgent endeavor that provides a rapid connection for science engagement between teachers/students and experts in an effort to fill the science outreach gap. National Lab Network (formerly National Lab Day, an ongoing initiative to increase science equity and literacy, provides a model for engaging the public in science via an E-matching and hands-on learning approach. We argue that science outreach should be a dynamic endeavor that changes according to the needs of a target school. We will describe a case study of a tailored science outreach activity in which a public school that serves mostly under-represented minority students from disadvantaged backgrounds were E-matched with a university, and subsequently became equal partners in the development of the science outreach plan. In addition, we will show how global science outreach endeavors may utilize a CBPA, like E-matching, to support a pipeline to science among under-represented minority students and students from disadvantaged backgrounds. By merging the CBPA concept with a practical case example, we hope to inform science outreach practices via the lens of a tailored E-matching approach.

    2013-11-01

    Full Text Available Plasma YKL-40 level has been reported as playing a significant role in community-acquired pneumonia (CAP. However, the correlation between plasma level of YKL-40 and the severity of CAP has not been reported. This study identifies the relationship between plasma level changes of the YKL-40 gene in adult patients hospitalized with CAP. The ELISA was used to measure the plasma YKL-40 level from 61 adult CAP patients before and after antibiotic treatment and from 60 healthy controls. The plasma YKL-40 levels were significantly increased in patients with CAP compared to normal controls. Moreover, the plasma concentration of YKL-40 correlated with the severity of CAP based on the pneumonia severity index (PSI score (r = 0.630, p < 0.001, the CURB-65 (confusion, uremia, respiratory rate, BP, age 65 years score (r = 0.640, p < 0.001, the Acute Physiology And Chronic Health Evaluation II (APACHE II score (r = 0.539, p < 0.001 and length of hospital stay (r = 0.321, p = 0.011, respectively. In conclusion, plasma YKL-40 may play a role in the diagnosis and clinical assessment of CAP severity, which could potentially guide the development of treatment strategies.

    The next frontier in the quest for magnetic fusion energy is the development of a basic understanding of plasma behavior in the regime of strong self-heating, the so called “burning plasma” regime. The general consensus in the fusion community is that the exploration of this frontier requires a new, relatively large experimental facility - a burning plasma experiment. The motivation, justification, and steps required to build such a facility are the primary focus of our report. The specific goals of the report are as follows. First, the report describes the critical scientific and engineering phenomena that are expected to arise for the first time, or else in a strongly modified form, in a burning plasma. Second, the report shows that the capabilities of existing experiments are inadequate to investigate these phenomena, thereby providing a major justification for a new facility. Third, the report compares the features and predicted performance of the three major next generation burning plasma experiments under current consideration (ITER-FEAT, FIRE, and IGNITOR), which are aimed at addressing these problems. Deliberately, no selection of the best option is made or attempted since such a decision involves complex scientific and cost issues that are beyond the scope of the present panel report. Fourth, the report makes specific recommendations regarding a process to move the burning plasma program forward, including a procedure for choosing the best option and the future activities of the Next Step Option (NSO) program. Fifth, the report attempts to provide a proper perspective for the role of burning plasmas with respect to the overall U.S. fusion program. The introduction provides the basic background information required for understanding the context in which the U.S. fusion community thinks about burning plasma issues. It “sets the stage” for the remainder of the report.

    Hasenkopf, C. A.

    2012-12-01

    Collaborative science in which scientists are able to form research questions based on the current body of scientific knowledge and get feedback from colleagues on their ideas and work is essential for pushing science forward. However, not all scientists are able to fully participate in the international science community. Scientists from developing countries can face barriers to communicating with the international community due to, among other issues: fewer scientists in their home country, difficulty in getting language-specific science writing training, fewer established pre-existing international collaborations and networks, and sometimes geographic isolation. These barriers not only result in keeping individual scientists from contributing their ideas, but they also slow down the progress of the scientific enterprise for everyone. Global Science Share (http://globalscienceshare.org/) is a new project, entering its pilot phase in Fall 2012, which will work to reduce this disparity by connecting young scientists and engineers from developing countries seeking to improve their technical writing with other scientists and engineers around the world via online collaborations. Scientist-volunteers act as mentors and are paired up with mentees according to their academic field and writing needs. The mentors give feedback and constructive technical and editorial criticisms on mentees' submitted pieces of writing through a four-step email discussion. Mentees gain technical writing skills, as well as make international connections with other scientists and engineers in fields related to their own. Mentors also benefit by gaining new international scientific colleagues and honing their own writing skills through their critiques. The Global Science Share project will begin its pilot phase by first inviting Mongolian science students to apply as mentees this fall. This abstract will introduce the Global Science Share program, present a progress report from its first

    2010-04-01

    Community-based participatory research (CBPR) has emerged in the last decades as a transformative research paradigm that bridges the gap between science and practice through community engagement and social action to increase health equity. CBPR expands the potential for the translational sciences to develop, implement, and disseminate effective interventions across diverse communities through strategies to redress power imbalances; facilitate mutual benefit among community and academic partners; and promote reciprocal knowledge translation, incorporating community theories into the research. We identify the barriers and challenges within the intervention and implementation sciences, discuss how CBPR can address these challenges, provide an illustrative research example, and discuss next steps to advance the translational science of CBPR.

    Since 1993, NASA has embedded education and public outreach (EPO) in its Earth and space science missions and research programs on the principle that science education is most effective when educators and scientists work hand-in-hand. Four Science EPO Forums organize the respective NASA Science Mission Directorate (SMD) Astrophysics, Earth Science, Heliophysics, and Planetary Science EPO programs into a coordinated, efficient, and effective nationwide effort. The result is significant, evaluated EPO impacts that support NASA's policy of providing a direct return-on-investment for the American public, advance STEM education and literacy, and enable students and educators to participate in the practices of science and engineering as embodied in the 2013 Next Generation Science Standards. This presentation by the leads of the four NASA SMD Science EPO Forums provides big-picture perspectives on NASA's effort to incorporate authentic science into the nation's STEM education and scientific literacy, highlighting tools that were developed to foster a collaborative community and examples of program effectiveness and impact. The Forums are led by: Astrophysics - Space Telescope Science Institute (STScI); Earth Science - Institute for Global Environmental Strategies (IGES); Heliophysics - University of California, Berkeley; and Planetary Science - Lunar and Planetary Institute (LPI).

    The Federal Government has a long history of cross-community coordination between the Scientific Research community, and the Earth Observations and Data Provider communities. Since 1998, the Federation of Earth Science Information Partners (ESIP), organically organized using a collective impact approach that fostered these interactions primarily around Earth science interoperability problems. Unlike most collaborations, collective impact initiatives named in 2011 by the Stanford Social Innovation Review, involve a backbone infrastructure, a dedicated staff, and a structured process that leads to a common agenda, shared measurement, continuous communication, and mutually reinforcing activities among all participants. Over the last ten years, the Foundation for Earth Science (FES) has a proven track record of providing backbone support to ESIP. This presentation will cover FES's general approach to providing backbone support that enables communities to define shared agenda and then will show these practices in two case studies: (1) ESIP at-large as a mature network of developed partnerships and (2) a new project, the Local Community Resilience cluster. This new cluster aims to bridge the gap from the established ESIP network to engage local communities in order to equip citizens, professionals, and other decision-makers with the scientific underpinning necessary to make informed decisions (bounce forward) for society by leveraging the strong existing ESIP community, the backbone capabilities of FES and extending Federal Earth Science, Technology and Innovation Investments.

    For the past eight years, the Coalition for Plasma Science (CPS) has presented an award for a plasma project at the Intel International Science and Engineering Fair (ISEF). We reported on the first five years of this award at the 2009 DPP Symposium. Pulsed neutron-producing experiments are a recurring topic, with the efforts now turning to applications. The most recent award at the Pittsburgh ISEF this past May was given for analysis of data from Brookhaven's Relativistic Heavy Ion Collider. The effort had the goal of understanding the fluid properties of the quark-gluon plasma. All of the CPS award-winning projects so far have been based on experiments, with four awards going to women students and four to men. In 2009 we noted that the number and quality of projects was improving. Since then, as we we predicted (hoped for), that trend has continued. The CPS looks forward to continuing its work with students who are excited about the possibilities of plasma. You too can share this excitement by judging at the 2013 fair in Phoenix on May 12-17.

    The purpose of the study is to show how science is defined and technology is selected in an Amish Mennonite (fundamentalist Christian) community and its school. Additionally, by examining this community, information is collected on how a fundamentalist school's treatment of and experience with science and technology compare to what has occurred over time in public schools in the United States. An ethnographic approach was used to recreate the shared beliefs, practices, artifacts, folk knowledge, and behaviors of this community. The ethnographic methodology allowed analytical descriptions and reconstructions of whole cultural scenes and groups of the community. Analysis of data followed an analytic induction method. The data collected included participant observation, documentation, photographs, formal interviews, informal interviews, audiotaping, journal entries, and artifacts. Findings indicate that science is wholly subsumed by Amish Mennonite religion. Using the transmission model, the Amish Mennonites teach science as a list of facts from the King James version of the Holy Bible. This method of teaching promotes community values and beliefs. The encouragement stands in sharp contrast to the Amish Mennonite school. Technology is seen as a tool for making the community prosper. For this community to sustain itself, economic stability must be maintained. Their economic stability is dependent on the outside community purchasing their goods and services; producing these goods and services requires use of appropriate technologies. In the United States public schools, science is encouraged to be taught a way of knowing that implies a critical view about how the world works. In addition, public schools promote new and innovative technologies. Thus, they become fertile soil for developing new concepts about implementing scientific ideas and using technology. For the Amish Mennonites, rigorous standards, such as the scientific method, as addressed in the public school do

    As coastal communities face a wide range of environmental changes, including threats from climate change, real-time data from cabled observatories can be used to support community members in making informed decisions about their coast and marine resources. Ocean Networks Canada (ONC) deploys and operates an expanding network of community observatories in the Arctic and coastal British Columbia, which enable communities to monitor real-time and historical data from the local marine environment. Community observatories comprise an underwater cabled seafloor platform and shore station equipped with a variety of sensors that collect environmental data 24/7. It is essential that data being collected by ONC instruments are relevant to community members and can contribute to priorities identified within the community. Using a community-based science approach, ONC is engaging local parties at all stages of each project from location planning, to instrument deployment, to data analysis. Alongside the science objectives, place-based educational programming is being developed with local educators and students. As coastal populations continue to grow and our use of and impacts on the ocean increase, it is vital that global citizens develop an understanding that the health of the ocean reflects the health of the planet. This presentation will focus on programs developed by ONC emphasizing the connection to place and local relevance with an emphasis on Indigenous knowledge. Building programs which embrace multiple perspectives is effective both in making ocean science more relevant to Indigenous students and in linking place-based knowledge to ocean science. The inclusion of Indigenous Knowledge into science-based monitoring programs also helps develop a more complete understanding of local conditions. We present a case study from the Canadian Arctic, in which ONC is working with Inuit community members to develop a snow and ice monitoring program to assist with predictions and

    With the foundation of the Division of Plasma Physics of the American Physical Society in April 1959, plasma physics was presented as the general study of ionized gases. This paper investigates the degree to which plasma physics, during its first decade, established a community of interrelated specialties, one that brought together work in gaseous electronics, astrophysics, controlled thermonuclear fusion, space science, and aerospace engineering. It finds that, in some regards, the plasma community was indeed greater than the sum of its parts and that its larger identity was sometimes glimpsed in inter-specialty work and studies of fundamental plasma behaviors. Nevertheless, the plasma specialties usually worked separately for two inter-related reasons: prejudices about what constituted "basic physics," both in the general physics community and within the plasma community itself; and a compartmentalized funding structure, in which each funding agency served different missions.

    A research project that is only expert-driven may ignore the role of local knowledge in research, often gives low priority to the development of a comprehensive strategy to engage the community, and may not deliver the results of the study to the community in an effective way. To date, only a limited number of co-created citizen science projects, where community members are involved in most or all steps of the scientific process, have been initiated at contaminated sites and even less in conjunction with risk communication. Gardenroots: The Dewey-Humboldt AZ Garden Project was a place-based, co-created citizen science project where community members and researchers together: defined the question for study, developed hypotheses, collected environmental samples, disseminated results broadly, translated the results into action, and posed new research questions. This co-created environmental research project produced new data and addressed an additional exposure route (consumption of vegetables grown in soils with elevated arsenic levels) that was not being evaluated in the current site assessment. Furthermore, co-producing science led to both individual learning and social-ecological outcomes. This approach illustrates the benefits of a co-created citizen-science program in addressing the complex problems that arise in communities neighboring a hazardous waste sites. Such a project increased the community's involvement in regional environmental assessment and decision-making, which has the potential to help mitigate environmental exposures and thereby reduce associated risks.

  14. Making big communities small: using network science to understand the ecological and behavioral requirements for community social capital.

    Neal, Zachary

    2015-06-01

    The concept of social capital is becoming increasingly common in community psychology and elsewhere. However, the multiple conceptual and operational definitions of social capital challenge its utility as a theoretical tool. The goals of this paper are to clarify two forms of social capital (bridging and bonding), explicitly link them to the structural characteristics of small world networks, and explore the behavioral and ecological prerequisites of its formation. First, I use the tools of network science and specifically the concept of small-world networks to clarify what patterns of social relationships are likely to facilitate social capital formation. Second, I use an agent-based model to explore how different ecological characteristics (diversity and segregation) and behavioral tendencies (homophily and proximity) impact communities' potential for developing social capital. The results suggest diverse communities have the greatest potential to develop community social capital, and that segregation moderates the effects that the behavioral tendencies of homophily and proximity have on community social capital. The discussion highlights how these findings provide community-based researchers with both a deeper understanding of the contextual constraints with which they must contend, and a useful tool for targeting their efforts in communities with the greatest need or greatest potential.

  15. Engaging underserved audiences in informal science education through community-based partnerships

    Bouzo, Suzanne

    This thesis explores the impact of the Science Education and Engagement of Denver (SEED) Partnership on three of its participant families. The partnership, consisting of large informal science organizations, as well as small community-based organizations, created its programming based on prior research identifying barriers to minority participation in informal science education programs. SEED aims to engage youth and families of emerging populations in science and nature. Three families were examined as a case study to have an in depth investigation about their involvement in the programs sponsored by the partnership. Findings suggest a positive impact on participant feelings and engagement in science and nature. Future recommendations are made for furthering programming as well as conducting a larger scale, more comprehensive program evaluation. This research addresses prior studies that have identified several barriers toward participation of underserved audiences in informal science education programs and how the SEED partnership has addressed specific identified barriers.

  16. A Comparison of Didactic and Inquiry Teaching Methods in a Rural Community College Earth Science Course

    Beam, Margery Elizabeth

    The combination of increasing enrollment and the importance of providing transfer students a solid foundation in science calls for science faculty to evaluate teaching methods in rural community colleges. The purpose of this study was to examine and compare the effectiveness of two teaching methods, inquiry teaching methods and didactic teaching methods, applied in a rural community college earth science course. Two groups of students were taught the same content via inquiry and didactic teaching methods. Analysis of quantitative data included a non-parametric ranking statistical testing method in which the difference between the rankings and the median of the post-test scores was analyzed for significance. Results indicated there was not a significant statistical difference between the teaching methods for the group of students participating in the research. The practical and educational significance of this study provides valuable perspectives on teaching methods and student learning styles in rural community colleges.

  17. Building Consensus on Community Standards for Reproducible Science

    As geochemists, the traditional model by which standard methods for generating, presenting, and using data have been generated relied on input from the community, the results of seminal studies, a variety of authoritative bodies, and has required a great deal of time. The rate of technological and related policy change has accelerated to the point that this historical model does not satisfy the needs of the community, publishers, or funders. The development of a new mechanism for building consensus raises a number of questions: Which aspects of our data are the focus of reproducibility standards? Who sets the standards? How do we subdivide the development of the consensus? We propose an open, transparent, and inclusive approach to the development of data and reproducibility standards that is organized around specific sub-disciplines and driven by the community of practitioners in those sub-disciplines. It should involve editors, program managers, and representatives of domain data facilities as well as professional societies, but avoid any single group to be the final authority. A successful example of this model is the Editors Roundtable, a cross section of editors, funders, and data facility managers that discussed and agreed on leading practices for the reporting of geochemical data in publications, including accessibility and format of the data, data quality information, and metadata and identifiers for samples (Goldstein et al., 2014). We argue that development of data and reproducibility standards needs to heavily rely on representatives from the community of practitioners to set priorities and provide perspective. Groups of editors, practicing scientists, and other stakeholders would be assigned the task of reviewing existing practices and recommending changes as deemed necessary. They would weigh the costs and benefits of changing the standards for that community, propose appropriate tools to facilitate those changes, work through the professional societies

    The Planetary Data System (PDS) has just released PDS4 Version 1.0, its next generation data standards for the planetary science archive. These data standards are the result of a multi-year effort to develop an information model based on accepted standards for data preservation, data curation, metadata management, and model development. The resulting information model is subsequently used to drive information system development from the generation of data standards documentation to the configuration of federated registries and search engines. This paper will provide an overview of the development of the PDS4 Information Model and focus on the application of the Open Archive Information System (OAIS) Reference Model - ISO 14721:2003, the Metadata Registry (MDR) Standard - ISO/IEC 11179, and the E-Business XML Standard to help ensure the long-term preservation and curation of planetary science data.

    The Large Synoptic Survey Telescope (LSST) will be a discovery machine for the astronomy and physics communities, revealing astrophysical phenomena from the Solar System to the outer reaches of the observable Universe. While many discoveries will be made using LSST data alone, taking full scientific advantage of LSST will require ground-based optical-infrared (OIR) supporting capabilities, e.g., observing time on telescopes, instrumentation, computing resources, and other infrastructure. This community-based study identifies, from a science-driven perspective, capabilities that are needed to maximize LSST science. Expanding on the initial steps taken in the 2015 OIR System Report, the study takes a detailed, quantitative look at the capabilities needed to accomplish six representative LSST-enabled science programs that connect closely with scientific priorities from the 2010 decadal surveys. The study prioritizes the resources needed to accomplish the science programs and highlights ways that existing, planne...

  20. Using the Culture in Science As Another Platform for Your Collaborative Community

    Caron, B. R.

    2014-12-01

    This talk will introduce notions of culture into the discussion of collaborative communities for the Earth sciences. One often hears that the problems of cyberinfrastructure, or of science in general are "half technical and half social." While this acknowledges that a purely technical solution is not possible, the reality is that nearly all of the funding for, and the attention and discussion about new collaborative communities is focused on technology. Recent attention to the need for governance (as opposed to management) has opened up some welcome conversations about the role of engagement in the success of collaborative communities. The talk will present the notion that the "half-social" side of the problem is also at least half again a cultural side. After clearing up some common misperceptions on the term "culture," the talk will explore the work of culture within science from its beginning and the availability of cultural tools to advance the vision and goals for collaborative communities in the Earth science. The emergence of organizational culture as the primary organizing feature of start-up companies in Silicon Valley and elsewhere presents new opportunities to reflect on the intentional use of cultural tools to sustain engagement in support of active, open science. Numerous critiques are now available for the cultural shortcomings of current scientific institutions, from universities, to agencies, to publishing houses. Indeed, institutional cultural factors are often seen as refractory to any intervention. The talk will present arguments that new models for intentional cultural work within emerging collaborative communities can serve to displace aspects of institutional culture that now work against the expansion of open science and shared data. Indeed, it may be that somewhat more than half of the remaining problems for open science can be solved through the use of reflexively applied intentional culture.

    In order to improve NASA's ability to provide an agile response to the needs of the Planetary Science Community, the Planetary Data System (PDS) is being transformed. NASA has used the highly successful virtual institute model (e.g., for NASA's Astrobiology Program) to re-compete the Science Nodes within the PDS Structure. We expect the new PDS will improve both archive searchability and product discoverability, continue the adaption of the new PDS4 Standard, and enhance our ability to work with other archive/curation activities within NASA and with the International community of space faring nations (through the International Planetary Data Alliance). PDS will continue to work with NASA missions from the initial Announcement of Opportunity through the end of mission to define, organize, and document the data. This process includes peer-review of data sets by members of the science community to ensure that the data sets are scientifically useful, effectively organized, and well documented. In this presentation we discuss recent changes in the PDS, and our future activities to build on these changes. Please visit our User Support Area at the meeting (Booth #446) if you have questions accessing our data sets or providing data to the PDS or about the new PDS structure.

    The adoption and implementation of evidence-based interventions (EBIs) are the goals of translational research; however, potential end-users' perceptions of an EBI value have contributed to low rates of adoption. In this article, we describe our application of emerging dissemination and implementation science theoretical perspectives, community engagement, and systems science principles to develop a novel EBI dissemination approach. Using consumer-driven, graphics-rich simulation, the approach demonstrates predicted implementation effects on health and employment outcomes for socioeconomically disadvantaged women at the local level and is designed to increase adoption interest of county program managers accountable for improving these outcomes in their communities.

    The University of Arizona’s Lunar and Planetary Laboratory (LPL) presents the 2nd Annual The Art of Planetary Science: An Exhibition (TAPS) on 17-19 October 2014. This art exhibition and competition features artwork inspired by planetary science, alongside works created from scientific data. It is designed to connect the local art and science communities of Tucson, and engage the public together in celebration of the beauty and elegance of the universe. The exhibition is organized by a team of volunteer graduate students, with the help of LPL’s Space Imaging Center, and support from the LPL administration. Last year’s inaugural event featured over 150 works of art from 70 artists and scientists. A variety of mediums were represented, including paintings, photography, digital prints, sculpture, glasswork, textiles, film, and written word. Over 300 guests attended the opening. Art submission and event attendance are free, and open to anyone.The primary goal of the event is to present a different side of science to the public. Too often, the public sees science as dull or beyond their grasp. This event provides scientists the opportunity to demonstrate the beauty that they find in their science, by creating art out of their scientific data. These works utilized, for example, equations, simulations, visual representations of spacecraft data, and images of extra-terrestrial material samples. Viewing these works alongside more traditional artwork inspired by those same scientific ideas provided the audience a more complex, multifaceted view of the content that would not be possible viewing either alone. The event also provides a way to reach out specifically to the adult community. Most science outreach is targeted towards engaging children in STEM fields. While this is vital for the long term, adults have more immediate control over the perception of science and public policy that provides funding and research opportunities to scientists. We hope this event raises

    Scott, Andrea

    Through distance learning, the community college system has moved beyond geographical boundaries to serve all students and provide educational opportunities at a distance to individuals previously out of reach of the college community. With the inception of the Mississippi Virtual Community College (MSVCC) in January 2000, Mississippi's public community colleges have experienced unprecedented growth in online enrollments and online course offerings to include the laboratory sciences; however, transfer of online lab science courses are problematic for individuals who wish to gain admittance to Medical, Dental, and Pharmacy schools in Mississippi. Currently online lab science courses are not accepted for transfer for students seeking admission to Mississippi Medical, Dental, or Pharmacy schools. The need for this study, the statement of the problem, and the purpose of the study address transfer issues related to the transfer of online lab science courses in Mississippi and the impact of such on the student and community college. The study also addresses existing doubts regarding online course delivery as a viable method of lab science delivery. The purpose of the study was to investigate differences between online instructional delivery as compared to traditional face-to-face delivery with the following research questions to: (1) Investigate the perception of quality of online courses as compared to traditional face-to-face courses. (2) Investigate the difference in student performance in online transfer lab science courses as compared to student performance in traditional face-to-face lab science courses. The results of this 13 semester study show significant differences in both perception of quality and student performance between online instructional delivery as compared to traditional face-to-face delivery. The findings demonstrate a need for Mississippi Dental, Medical, and Pharmacy schools to reexamine the articulation agreement between IHL and Community and

    The International Space Station (ISS) program utilizes a plasma environment forecast for estimating electrical charging hazards for crews during extravehicular activity (EVA). The process uses ionospheric electron density (Ne) and temperature (Te) measurements from the ISS Floating Potential Measurement Unit (FPMU) instrument suite with the assumption that the plasma conditions will remain constant for one to fourteen days with a low probability for a space weather event which would significantly change the environment before an EVA. FPMU data is typically not available during EVA's, therefore, the most recent FPMU data available for characterizing the state of the ionosphere during EVA is typically a day or two before the start of an EVA or after the EVA has been completed. Three near real time space weather tools under development for ISS applications are described here including: (a) Ne from ground based ionosonde measurements of foF2 (b) Ne from near real time satellite radio occultation measurements of electron density profiles (c) Ne, Te from a physics based ionosphere model These applications are used to characterize the ISS space plasma environment during EVA periods when FPMU data is not available, monitor for large changes in ionosphere density that could render the ionosphere forecast and plasma hazard assessment invalid, and validate the "persistence of conditions" forecast assumption. In addition, the tools are useful for providing space environment input to science payloads on ISS and anomaly investigations during periods the FPMU is not operating.

    The goal of this project is to promote Lyme disease prevention and to cultivate an interest in science through a citizen-science project coordinated by researchers at a public university and teachers at rural high schools. The lesson plan is designed to increase student interest in pursuing a science career through participation in an authentic research experience, utilizing a topic that has implications on the health of the surrounding community. Students are introduced in the classroom to zoonotic diseases transmitted by the Ixodes tick, the health risks of Lyme disease, and disease prevention strategies. Students then participate in a research experience collecting field data and ticks from their community, which are used in university research. To measure changes in student knowledge and attitudes toward Lyme disease and science careers, students completed surveys related to the learning objectives associated with the experience. We found participation in the activity increased student confidence and ability to correctly differentiate a deer tick from a wood tick and to recognize the symptoms of Lyme disease. In addition, students reported increased interest in pursuing a science degree in college or graduate school. Authentic research experience related to a disease relevant to the local community is effective at enhancing high school student engagement in science.

  10. Observatories, think tanks, and community models in the hydrologic and environmental sciences: How does it affect me?

    Torgersen, Thomas

    2006-06-01

    Multiple issues in hydrologic and environmental sciences are now squarely in the public focus and require both government and scientific study. Two facts also emerge: (1) The new approach being touted publicly for advancing the hydrologic and environmental sciences is the establishment of community-operated "big science" (observatories, think tanks, community models, and data repositories). (2) There have been important changes in the business of science over the last 20 years that make it important for the hydrologic and environmental sciences to demonstrate the "value" of public investment in hydrological and environmental science. Given that community-operated big science (observatories, think tanks, community models, and data repositories) could become operational, I argue that such big science should not mean a reduction in the importance of single-investigator science. Rather, specific linkages between the large-scale, team-built, community-operated big science and the single investigator should provide context data, observatory data, and systems models for a continuing stream of hypotheses by discipline-based, specialized research and a strong rationale for continued, single-PI ("discovery-based") research. I also argue that big science can be managed to provide a better means of demonstrating the value of public investment in the hydrologic and environmental sciences. Decisions regarding policy will still be political, but big science could provide an integration of the best scientific understanding as a guide for the best policy.

    The Tritium Plasma Experiment (TPE) is a unique high-flux linear plasma device that can handle beryllium, tritium, and neutron-irradiated plasma facing materials, and is the only existing device dedicated to directly study tritium retention and permeation in neutron-irradiated materials with tritium [M. Shimada et.al., Rev. Sci. Instru. 82 (2011) 083503 and and M. Shimada, et.al., Nucl. Fusion 55 (2015) 013008]. The plasma-material-interaction (PMI) determines a boundary condition for diffusing tritium into bulk PFCs, and the tritium PMI is crucial for enhancing fundamental sciences that dictate tritium fuel cycles and safety and are high importance to an FNSF and DEMO. Recently the TPE has undergone major upgrades in its electrical and control systems. New DC power supplies and a new control center enable remote plasma operations from outside of the contamination area for tritium, minimizing the possible exposure risk with tritium and beryllium. We discuss the electrical upgrade, enhanced operational safety, improved plasma performance, and development of optical spectrometer system. This upgrade not only improves operational safety of the worker, but also enhances plasma performance to better simulate extreme plasma-material conditions expected in ITER, Fusion Nuclear Science Facility (FNSF), and Demonstration reactor (DEMO).

    What are the links between mainstream climate science and local community knowledge? This study takes the example of Greenland, considered one of the regions most impacted by climate change, and Inuit people, characterized as being highly adaptive to environmental change, to explore this question. The study is based on 10 years of anthropological participatory research in Uummannaq, Northwest Greenland, along with two fieldwork periods in October 2014 and April 2015, and a quantitative bibliometric analysis of the international literature on sea ice - a central subject of concern identified by Uummannaq community members during the fieldwork periods. Community members' perceptions of currently available scientific climate knowledge were also collected during the fieldwork. This was done to determine if community members consider available scientific knowledge salient and if it covers issues they consider relevant. The bibliometric analysis of the sea ice literature provided additional insight into the degree to which scientific knowledge about climate change provides information relevant for the community. Our results contribute to the ongoing debate on the missing connections between community worldviews, cultural values, livelihood needs, interests and climate science. Our results show that more scientific research efforts should consider local-level needs in order to produce local-scale knowledge that is more salient, credible and legitimate for communities experiencing climate change. In Uummannaq, as in many Inuit communities with similar conditions, more research should be done on sea ice thickness in winter and in areas through which local populations travel. This paper supports the growing evidence that whenever possible, climate change research should focus on environmental features that matter to communities, at temporal and spatial scales relevant to them, in order to foster community adaptations to change. We recommend such research be connected to and

    The UCLA Plasma Simulation Group is a major partner of the “Community Petascale Project for Accelerator Science and Simulation”. This is the final technical report. We include an overall summary, a list of publications, progress for the most recent year, and individual progress reports for each year. We have made tremendous progress during the three years. SciDAC funds have contributed to the development of a large number of skeleton codes that illustrate how to write PIC codes with a hierarchy of parallelism. These codes cover 2D and 3D as well as electrostatic solvers (which are used in beam dynamics codes and quasi-static codes) and electromagnetic solvers (which are used in plasma based accelerator codes). We also used these ideas to develop a GPU enabled version of OSIRIS. SciDAC funds were also contributed to the development of strategies to eliminate the Numerical Cerenkov Instability (NCI) which is an issue when carrying laser wakefield accelerator (LWFA) simulations in a boosted frame and when quantifying the emittance and energy spread of self-injected electron beams. This work included the development of a new code called UPIC-EMMA which is an FFT based electromagnetic PIC code and to new hybrid algorithms in OSIRIS. A new hybrid (PIC in r-z and gridless in φ) algorithm was implemented into OSIRIS. In this algorithm the fields and current are expanded into azimuthal harmonics and the complex amplitude for each harmonic is calculated separately. The contributions from each harmonic are summed and then used to push the particles. This algorithm permits modeling plasma based acceleration with some 3D effects but with the computational load of an 2D r-z PIC code. We developed a rigorously charge conserving current deposit for this algorithm. Very recently, we made progress in combining the speed up from the quasi-3D algorithm with that from the Lorentz boosted frame. SciDAC funds also contributed to the improvement and speed up of the quasi-static PIC

    The Suomi National Polar-orbiting Partnership (S-NPP) and Joint Polar Satellite System (JPSS) High Rate Data (HRD) link provides Direct Broadcast data to users in real-time, utilizing their own remote field terminals. The Field Terminal Support (FTS) provides the resources needed to support the Direct Readout communities by providing software, documentation, and periodic updates to enable them to produce data products from SNPP and JPSS. The FTS distribution server will also provide the necessary ancillary and auxiliary data needed for processing the broadcasts, as well as making orbital data available to assist in locating the satellites of interest. In addition, the FTS provides development support for the algorithm and software through GSFC Direct Readout Laboratory (DRL) International Polar Orbiter Processing Package (IPOPP) and University of Wisconsin (UWISC) Community Satellite Processing Package (CSPP), to enable users to integrate the algorithms into their remote terminals. The support the JPSS Program provides to the institutions developing and maintaining these two software packages, will demonstrate the ability to produce ready-to-use products from the HRD link and provide risk reduction effort at a minimal cost. This paper discusses the key functions and system architecture of FTS.

    Collaborative research between WVU and PPPL was carried out at WVU for the purpose of incorporating the sophisticated diagnostic technique known as laser-induced fluorescence (LIF) in the Paul-Trap Simulation Experiment (PTSX) at PPPL. WVU assembled a LIF system at WVU, transported it to PPPL, helped make LIF experiments on the PTSX device, participated in PTSX science, and trained PPPL staff in LIF techniques. In summary, WVU refurbished a non-operational LIF system being loaned from University of Maryland to PPPL and, by doing so, provided PPPL with additional diagnostic capability for its PTSX device and other General Plasma Science experiments. WVU students, staff, and faculty will visit PPPL to collaborate on PTSX experiments in the future.

    Despite years of research and investment, we have yet to see the widespread implementation of a myriad research-proven instructional strategies in STEM education[1]. To address this challenge, we present and analyze one such strategy, a theoretically-grounded model of university-community partnership [2] that engages university students and children in a collective enterprise that has the potential to improve the participation and education of all. We document the impact of this effort on: university participants who learn about education, the community and science; children in the community who learn about science, the nature of science and develop their identities and attitudes towards science; and, shifts in institutional structures which may allow these programs to be part of standard practice. This project is designed to be sustained and scaled, and is analyzed through the application of a new framework [3] which brings together theories of STEM change that come from studies in higher education, faculty development and disciplinary-based education research in STEM.

  20. 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"

    Science.gov (United States)

    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

  1. Science in the community: An ethnographic account of social material transformation

    Science.gov (United States)

    Lee, Stuart Henry

    This dissertation is about the learning and use of science at the level of local community. It is an ethnographic account, and its theoretical approach draws on actor-network theory as well as neo-Marxist practice theory and the related notion of situated cognition. This theoretical basis supports a work that focuses on the many heterogeneous transformations that materials and people undergo as science is used to help bring about social and political change in a quasi-rural community. The activities that science becomes involved in, and the hybrid formations as it encounters local issues are stressed. Learning and knowing as outcomes of community action are theorized. The dissertation links four major themes throughout its narrative: scientific literacy, representations, relationships and participatory democracy. These four themes are not treated in isolation. Different facets of their relation to each other are stressed in different chapters, each of which analyze different particular case studies. This dissertation argues for the conception of a local scientific praxis, one that is markedly different than the usual notion of science, yet is necessary for the uptake of scientific information into a community.

    This report describes the findings of the effort initiated by the Arab Science and Technology Foundation and the Cooperative Monitoring Center at Sandia National Laboratories to identify, contact, and engage members of the Iraqi science and technology (S&T) community. The initiative is divided into three phases. The first phase, the survey of the Iraqi scientific community, shed light on the most significant current needs in the fields of science and technology in Iraq. Findings from the first phase will lay the groundwork for the second phase that includes the organization of a workshop to bring international support for the initiative, and simultaneously decides on an implementation mechanism. Phase three involves the execution of outcomes of the report as established in the workshop. During Phase 1 the survey team conducted a series of trips to Iraq during which they had contact with nearly 200 scientists from all sections of the country, representing all major Iraqi S&T specialties. As a result of these contacts, the survey team obtained over 450 project ideas from Iraqi researchers. These projects were revised and analyzed to identify priorities and crucial needs. After refinement, the result is approximately 170 project ideas that have been categorized according to their suitability for (1) developing joint research projects with international partners, (2) engaging Iraqi scientists in solving local problems, and (3) developing new business opportunities. They have also been ranked as to high, medium, or low priority.

    This article is the first to describe the discoursal construction of an adolescent community of practice (CoP) in a non-school setting. CoPs can provide optimal learning environments. The adolescent community centered around science journalism and positioned itself dichotomously in relationship to school literacy practices. The analysis focuses on recordings from a panel-style research interview from an early implementation of the Science Literacy Through Science Journalism (SciJourn) project. Researchers trained high school students participating in a youth development program to write science news articles. Students engaged in the authentic practices of professional science journalists, received feedback from a professional editor, and submitted articles for publication. I used a fine-grained critical discourse analysis of genre, discourse, and style to analyze student responses about differences between writing in SciJourn and in school. Students described themselves as agentic in SciJourn and passive in school, using an academic writing discourse of deficit to describe schooling experiences. They affiliated with and defined a SciJourn CoP, constructing positive journalistic identities therein. Educators are encouraged to develop similar CoPs. The discursive features presented may be used to monitor the development of communities of practice in a variety of settings.

    The river basin is a fundamental unit of the landscape and water in that defined landscape plays a central role in shaping the land surface, in dissolving minerals, in transporting chemicals, and in determining species distribution. Therefore, the river basin is a natural observatory for examining hydrologic phenomena and the complex interaction of physical, chemical, and biological processes that control them. CUAHSI, incorporated in 2001, is a community-based research infrastructure initiative formed to mobilize the hydrologic community through addressing key science questions and leveraging nationwide hydrologic resources from its member institutions and collaborative partners. Through an iterative community-based process, it has been previously proposed to develop a network of hydrologic infrastructure that organizes around scales on the order of 10,000 km2 to examine critical interfaces such as the land-surface, atmosphere, and human impact. Data collection will characterize the stores, fluxes, physical pathways, and residence time distributions of water, sediment, nutrients, and contaminants coherently at nested scales. These fundamental properties can be used by a wide range of scientific disciplines to address environmental questions. This more complete characterization will enable new linkages to be identified and hypotheses to be tested more incisively. With such a research platform, hydrologic science can advance beyond measuring streamflow or precipitation input to understanding how the river basin functions in both its internal processes and in responding to environmental stressors. That predictive understanding is needed to make informed decisions as development and even natural pressures stress existing water supplies and competing demands for water require non-traditional solutions that take into consideration economic, environmental, and social factors. Advanced hydrologic infrastructure will enable research for a broad range of multidisciplinary

    For more than two decades, the Hubble EPO program has sought to bring the wonders of the universe to the education community and the public, and to engage audiences in the adventure of scientific discovery. Program components include standards-based, curriculum-support materials, exhibits and exhibit components, and professional development workshops. The main underpinnings of the program's infrastructure are scientist-educator development teams, partnerships, and an embedded program evaluation component. The Space Telescope Science Institute's Office of Public Outreach is leveraging this existing infrastructure to bring the Frontier Fields science program to the education community in a cost-effective way. Frontier Fields observations and results have been, and will continue to be, embedded into existing product lines and professional development offerings. We also are leveraging our new social media strategy to bring the science program to the public in the form of an ongoing blog.

    In this study, the participants conceptualized and implemented an action research project that focused on the infusion of inquiry principles into a neglected science curriculum. Specific objectives were to find (a) What factors challenge and support the evolution of an action research community of practice? (b) How are teachers’ beliefs about science teaching and learning transformed? and (c) How does teachers’ knowledge of curriculum, instruction, assessment, and student learning change as a result of learning within a community of practice? In this instrumental case study (Stake 2000, In N. K. Denzin, & Y. S. Lincoln (Eds.), Handbook of qualitative research (pp. 435-454). Thousand Oaks, CA: Sage), a range of data collection sources and methods were adopted. Outcomes focus on how the design principles for cultivating a community of practice emerged in the action research group, as well as the types of teacher learning that occurred by engaging in action research.

  17. The technology and science of steady-state operation in magnetically confined plasmas

    The steady-state operation of magnetically confined fusion plasmas is considered as one of the 'grand challenges' of future decades, if not the ultimate goal of the research and development activities towards a new source of energy. Reaching such a goal requires the high-level integration of both science and technology aspects of magnetic fusion into self-consistent plasma regimes in fusion-grade devices. On the physics side, the first constraint addresses the magnetic confinement itself which must be made persistent. This means to either rely on intrinsically steady-state configurations, like the stellarator one, or turn the inductively driven tokamak configuration into a fully non-inductive one, through a mix of additional current sources. The low efficiency of the external current drive methods and the necessity to minimize the re-circulating power claim for a current mix strongly weighted by the internal 'pressure driven' bootstrap current, itself strongly sensitive to the heat and particle transport properties of the plasma. A virtuous circle may form as the heat and particle transport properties are themselves sensitive to the current profile conditions. Note that several other factors, e.g. plasma rotation profile, magneto-hydro-dynamics activity, also influence the equilibrium state. In the present tokamak devices, several examples of such 'advanced tokamak' physics research demonstrate the feasibility of steady-state regimes, though with a number of open questions still under investigation. The modelling activity also progresses quite fast in this domain and supports understanding and extrapolation. This high level of physics sophistication of the plasma scenario however needs to be combined with steady-state technological constraints. The technology constraints for steady-state operation are basically twofold: the specific technologies required to reach the steady-state plasma conditions and the generic technologies linked to the long pulse operation of a

    Professional Learning Community Model for Alternative Pathways (PLC-MAP) is a partnership of North Harris Montgomery Community Colleges, Texas A&M University, and 11 urban, suburban, and rural school districts in the Greater Houston area focused on developing a professional learning community that increases the retention and quality of middle and high school mathematics and science teachers who are being certified through the NHMCCD Alternative Certification Program. Improved quality in teaching refers to increased use of effective inquiry teaching strategies, including information technology where appropriate, that engage students to ask worthy scientific questions and to reason, judge, explain, defend, argue, reflect, revise, and/or disseminate findings. Novice teachers learning to adapt or designing authentic inquiry in their classrooms face two enormous problems. First, there are important issues surrounding the required knowledgebase, habit of mind, and pedagogical content knowledge of the teachers that impact the quality of their lesson plans and instructional sequences. Second, many ACP intern teachers teach under challenging conditions with limited resources, which impacts their ability to implement authentic inquiry in the classroom. Members of our professional learning community, including scientists, mathematicians and master teachers, supports novice teachers as they design lesson plans that engage their students in authentic inquiry. The purpose of this research was to determine factors that contribute to success or barriers that prevent ACP secondary science intern and induction year teachers from gaining knowledge and engaging in classroom inquiry as a result of an innovative professional development experience. A multi-case study design was used for this research. We adopted a two-tail design where cases from both extremes (good and poor gains) were deliberately chosen. Six science teachers were selected from a total of 40+ mathematics and science

    2000-10-01

    The number of women and underrepresented minorities in plasma science is woefully small.The Princeton Plasma Physics Laboratory (PPPL), for example, consists of 2% women and underrepresented minorities. The historical reasons for this specific case as well as the overall circumstances involving pipeline inclusion are beyond the scope of this paper. The answer, however, is clearly NOT a lack of qualified women and minorities as evidenced by the numbers in other SEM disciplines such as computer science where women earn 27% of the doctoral degrees, African Americans 10% and Hispanics 5%. Over the past five years the number of underrepresented minorities earning degrees in physics and engineering has risen. Since 1995, in an effort to reach this population, PPPL has actively recruited women and underrepresented minority students to its various undergraduate research programs, in particular the National Undergraduate Fellowship Program (NUF) and the Energy Research Undergraduate Laboratory Fellowship (ERULF). The results are encouraging. The details of our efforts, our future plans, and ways of introducing our methods to other laboratories will be discussed.

    The Linked Vocabulary API is a specification for publishing RESTful APIs of vocabularies represented in the Simple Knowledge Organization System (SKOS) as Linked Data on the web. This work began as part of the Coastal and Marine Spatial Planning Vocabularies (CMSPV) project in response to the need for a standard manner for agencies to publish and consume hierarchical vocabularies on the web. The RESTful architecture of the API provides a simple mechanism for consumption of full vocabularies, single vocabulary terms, related terms, and searches on terms. The Linked Data nature of the API promotes interoperability by exposing vocabulary resources as resolvable URIs that may be referenced from other vocabularies or sources of Linked Data and by allowing the published vocabulary to contain references as links to terms from other vocabularies. The Linked Vocabulary API is formally defined in a Linked Data API specification and may be deployed using standard implementations of the Linked Data API such as the Epimorphics Linked Data API (ELDA). Recent presentations of work done with the Linked Vocabulary API as part of the CMSPV project have resulted in the API receiving growing interest from the broader scientific community. In this contribution we present the Linked Vocabulary API design and deployment process.

    The CosmoQuest Virtual Research Facility invites the public to participate in NASA Science Mission Directorate related research that leads to publishable results and data catalogues. CosmoQuest projects range in difficulty from simple crater and transient marking tasks to more complicated mapping tasks. To successfully engage contributors in creating usable results, training and validation are required. This is accomplished through activities that are designed to mirror the experiences students would have in a university, and include mentoring by team scientists, feedback on contributor efforts, seminars to learn about new science, and even formal classes to provide needed background. Recruitment is accomplished using new and social media, and planetarium and Science on the Sphere™ trailers and shows, and community is built through online and real-world collaboration spaces and events. In this presentation, we detail CosmoQuest's four-pronged approach of media recruitment, science education, citizen science, and community collaboration. We also discuss how it is leveraged to create a skilled collaboration of citizen scientists. Training and data validation activities will be be emphasized, with examples of both what can go right and lessons learned from when things go wrong. We conclude with strategies on how to utilize best practices in user interface design to create virtual experiences that allow major citizen science efforts to be scalable to large audiences.

    The Planetary Data System (PDS), NASA's long-term archive for solar system exploration data, has just released PDS4, a modernization of the PDS architecture, data standards, and technical infrastructure. This next generation system positions the PDS to meet the demands of the coming decade, including big data, international cooperation, distributed nodes, and multiple ways of analysing and interpreting data. It also addresses three fundamental project goals: providing more efficient data delivery by data providers to the PDS, enabling a stable, long-term usable planetary science data archive, and enabling services for the data consumer to find, access, and use the data they require in contemporary data formats. The PDS4 information architecture is used to describe all PDS data using a common model. Captured in an ontology modeling tool it supports a hierarchy of data dictionaries built to the ISO/IEC 11179 standard and is designed to increase flexibility, enable complex searches at the product level, and to promote interoperability that facilitates data sharing both nationally and internationally. A PDS4 information architecture design requirement stipulates that the content of the information model must be translatable to external data definition languages such as XML Schema, XMI/XML, and RDF/XML. To support the semantic Web standards we are now in the process of mapping the contents into RDF/XML to support SPARQL capable databases. We are also building a terminological ontology to support virtually unified data retrieval and access. This paper will provide an overview of the PDS4 information architecture focusing on its domain information model and how the translation and mapping are being accomplished.

    2014-12-01

    The prupose of this paper is to present the "Adaptation Research a Transdisciplinary community and policy centered appoach" (ARTisticc) project. ARTisticc's goal is to apply innovative standardized transdisciplinary art and science integrative approaches to foster robust, socially, culturally and scientifically, community centred adaptation to climate change. The approach used in the project is based on the strong understanding that adaptation is: (a) still "a concept of uncertain form"; (b) a concept dealing with uncertainty; (c) a concept that calls for an analysis that goes beyond the traditional disciplinary organization of science, and; (d) an unconventional process in the realm of science and policy integration. The project is centered on case studies in France, Greenland, Russia, India, Canada, Alaska, and Senegal. In every site we jointly develop artwork while we analyzing how natural science, essentially geosciences can be used in order to better adapt in the future, how society adapt to current changes and how memories of past adaptations frames current and future processes. Artforms are mobilized in order to share scientific results with local communities and policy makers, this in a way that respects cultural specificities while empowering stakeholders, ARTISTICC translates these "real life experiments" into stories and artwork that are meaningful to those affected by climate change. The scientific results and the culturally mediated productions will thereafter be used in order to co-construct, with NGOs and policy makers, policy briefs, i.e. robust and scientifically legitimate policy recommendations regarding coastal adaptation. This co-construction process will be in itself analysed with the goal of increasing arts and science's performative functions in the universe of evidence-based policy making. The project involves scientists from natural sciences, the social sciences and the humanities, as well as artitis from the performing arts (playwriters

    Native Americans are poorly represented in all science, technology and engineering fields. This under- representation results from numerous cultural, economic, and historical factors. The Elwha Science Education Project (ESEP), initiated in 2007, strives to construct a culturally-integrated, geoscience education program for Native American young people through engagement of the entire tribal community. The ESEP has developed a unique approach to informal geoscience education, using environmental restoration as a centerpiece. Environmental restoration is an increasingly important goal for tribes. By integrating geoscience activities with community tradition and history, project stakeholders hope to show students the relevance of science to their day-to-day lives. The ESEP's strength lies in its participatory structure and unique network of partners, which include Olympic National Park; the non-profit, educational center Olympic Park Institute (OPI); a geologist providing oversight and technical expertise; and the Lower Elwha Tribe. Lower Elwha tribal elders and educators share in all phases of the project, from planning and implementation to recruitment of students and discipline. The project works collaboratively with tribal scientists and cultural educators, along with science educators to develop curriculum and best practices for this group of students. Use of hands-on, place-based outdoor activities engage students and connect them with the science outside their back doors. Preliminary results from this summer's middle school program indicate that most (75% or more) students were highly engaged approximately 90% of the time during science instruction. Recruitment of students has been particularly successful, due to a high degree of community involvement. Preliminary evaluations of the ESEP's outcomes indicate success in improving the outlook of the tribe's youth towards the geosciences and science, in general. Future evaluation will be likewise participatory

    This study examined implications of the economic downturn that began in December 2007 for the Community Youth Development Study (CYDS), a longitudinal randomized controlled trial of the Communities That Care (CTC) prevention system. The downturn had the potential to affect the internal validity of the CYDS research design and implementation of science-based prevention in study communities. We used archival economic indicators and community key leader reports of economic conditions to assess the extent of the economic downturn in CYDS communities and potential internal validity threats. We also examined whether stronger economic downturn effects were associated with a decline in science-based prevention implementation. Economic indicators suggested the downturn affected CYDS communities to different degrees. We found no evidence of systematic differences in downturn effects in CTC compared to control communities that would threaten internal validity of the randomized trial. The Community Economic Problems scale was a reliable measure of community economic conditions, and it showed criterion validity in relation to several objective economic indicators. CTC coalitions continued to implement science-based prevention to a significantly greater degree than control coalitions 2 years after the downturn began. However, CTC implementation levels declined to some extent as unemployment, the percentage of students qualifying for free lunch, and community economic problems worsened. Control coalition implementation levels were not related to economic conditions before or after the downturn, but mean implementation levels of science-based prevention were also relatively low in both periods.

  6. Discourse in science communities: Issues of language, authority, and gender in a life sciences laboratory

    Science.gov (United States)

    Conefrey, Theresa Catherine

    Government-sponsored and private research initiatives continue to document the underrepresentation of women in the sciences. Despite policy initiatives, women's attrition rates each stage of their scientific careers remain higher than those of their male colleagues. In order to improve retention rates more information is needed about why many drop out or do not succeed as well as they could. While broad sociological studies and statistical surveys offer a valuable overview of institutional practices, in-depth qualitative analyses are needed to complement these large-scale studies. This present study goes behind statistical generalizations about the situation of women in science to explore the actual experience of scientific socialization and professionalization. Beginning with one reason often cited by women who have dropped out of science: "a bad lab experience," I explore through detailed observation in a naturalistic setting what this phrase might actually mean. Using ethnographic and discourse analytic methods, I present a detailed analysis of the discourse patterns in a life sciences laboratory group at a large research university. I show how language accomplishes the work of indexing and constituting social constraints, of maintaining or undermining the hierarchical power dynamics of the laboratory, of shaping members' presentation of self, and of modeling social and professional skills required to "do science." Despite the widespread conviction among scientists that "the mind has no sex," my study details how gender marks many routine interactions in the lab, including an emphasis on competition, a reinforcement of sex-role stereotypes, and a conversational style that is in several respects more compatible with men's than women's forms of talk.

  7. Dropping Out of Computer Science: A Phenomenological Study of Student Lived Experiences in Community College Computer Science

    Gilbert-Valencia, Daniel H.

    California community colleges contribute alarmingly few computer science degree or certificate earners. While the literature shows clear K-12 impediments to CS matriculation in higher education, very little is known about the experiences of those who overcome initial impediments to CS yet do not persist through to program completion. This phenomenological study explores insights into that specific experience by interviewing underrepresented, low income, first-generation college students who began community college intending to transfer to 4-year institutions majoring in CS but switched to another field and remain enrolled or graduated. This study explores the lived experiences of students facing barriers, their avenues for developing interest in CS, and the persistence support systems they encountered, specifically looking at how students constructed their academic choice from these experiences. The growing diversity within California's population necessitates that experiences specific to underrepresented students be considered as part of this exploration. Ten semi-structured interviews and observations were conducted, transcribed and coded. Artifacts supporting student experiences were also collected. Data was analyzed through a social-constructivist lens to provide insight into experiences and how they can be navigated to create actionable strategies for community college computer science departments wishing to increase student success. Three major themes emerged from this research: (1) students shared pre-college characteristics; (2) faced similar challenges in college CS courses; and (3) shared similar reactions to the "work" of computer science. Results of the study included (1) CS interest development hinged on computer ownership in the home; (2) participants shared characteristics that were ideal for college success but not CS success; and (3) encounters in CS departments produced unique challenges for participants. Though CS interest was and remains

    To increase diversity in one influential science community, a consortium of public and private institutions created the Woods Hole Partnership Education Program, or PEP, in 2008. Participating institutions are the Marine Biological Laboratory, Northeast Fisheries Science Center of NOAA's Fisheries Service, Sea Education Association, U.S. Geological Survey, Woods Hole Oceanographic Institution, the Woods Hole Research Center, and University of Maryland Eastern Shore. Aimed at college juniors and seniors with some course work in marine and/or environmental sciences, PEP is a four-week course and a six-to-eight-week individual research project under the guidance of a research mentor. Forty-six students have participated to date. Investigators from the science institutions serve as course faculty and research mentors. We listened to experts regarding critical mass, mentoring, adequate support, network recruitment, and then built a program based on those features. Three years in we have a program that works and that has its own model for choosing applicants and for matching with mentors. We continue fine-tuning our match process, enhancing mentoring skills, preparing our students for a variety of lab cultures, and setting expectations high while remaining supportive. Our challenges now are to keep at it, using leverage instead of capacity to make a difference. Collaboration, not competition, is key since a rising tide floats all boats.

    Full Text Available Exposing K–12 students to cutting edge science that impacts their daily lives can bring classroom lessons to life. Citizen-science projects are an excellent way to bring high-level science to the classroom and help satisfy one of the cornerstone concepts of the Next Generation Science Standards (NGSS, “engaging in practices that scientists and engineers actually use.” This can be a daunting task for teachers who may lack the background or resources to integrate these projects into the classroom. This is where scientific societies such as the American Society for Microbiology (ASM can play a critical role. ASM encourages its members to engage with the K–12 community by providing networking opportunities and resources for ASM members and K–12 teachers to work together to bring microbiology into the classroom.

    1996-04-01

    Between 1920 and 1960 astronomers began working with scientists in other fields in order to better understand the nature of the solar system. Researchers made wide-ranging attempts to solve such problems as the nature of lunar and terrestrial craters, the origin of comets and meteors, and the birth of the solar system. While often tinged with controversy, this work provided the foundation for planetary science in the space age. Exploiting previously unused archival material, Ronald Doel investigates this emerging interdisciplinary scientific community and its influence on astronomy, meteorology, geology, and geophysics. He examines how studies in planetary science were influenced by shifts in institutional mandates, new research techniques, and Cold War government-military funding. Above all, the book explores an important branch of what is now called the environmental sciences. This book will interest historians of science as well as astronomers.

    1986-01-01

    Large, permanently-manned space platforms can provide exciting opportunities for discoveries in basic plasma and geoplasma sciences. The potential for these discoveries will depend very critically on the properties of the platform, its subsystems, and their abilities to fulfill a spectrum of scientific requirements. With this in mind, the planning of space station research initiatives and the development of attendant platform engineering should allow for the identification of critical science and technology issues that must be clarified far in advance of space station program implementation. An attempt is made to contribute to that process, with a perspective that looks to the development of the space station as a permanently-manned Spaceborne Ionospheric Weather Station. The development of this concept requires a synergism of science and technology which leads to several critical design issues. To explore the identification of these issues, the development of the concept of an Ionospheric Weather Station will necessarily touch upon a number of diverse areas. These areas are discussed.

    Using a quasi-experimental, nonequivalent pretest/posttest control group design, the researchers examined the effects of online collaborative learning on eighth-grade student's sense of community in a physical science class. For a 9-week period, students in the control group participated in collaborative activities in a face-to-face learning environment, whereas students in the experimental group participated in online collaborative activities using the Edmodo educational platform in a hybrid learning environment. Students completed the Classroom Community Scale survey as a pretest and posttest. Results indicated that the students who participated in the face-to-face classroom had higher overall sense of community and learning community than students who participated in collaborative activities in the online environment. Results and implications are discussed and suggestions for future research are provided.

    Full Text Available Educating broadly about the science and technologies of sustainability is essential, because it convinces us that a successfully sustainable future is being undermined. The reason we need to seek a world view compatible with sustainability becomes evident. Education helps to remove the scales from our eyes; it can cure our blindness. But then we have to take the other step – deal with our addiction and denial.

    Dhingra, Koshi

    2008-04-01

    In this essay review, four studies around the themes of identity and globalization are summarized and analyzed. The researchers' perspectives are generally grounded in Brown and Campione's ideas on situated knowledge ( Classroom lessons: Integrating cognitive theory and classroom practice (pp. 229-270). Cambridge: The MIT Press/Bradford Books, 1994) and Lave and Wenger's definition of learning as an activity fostered through participation in communities of practice ( Situated learning. Legitimate peripheral participation. Cambridge: University of Cambridge Press, 1991). Questions about the goals of science education spaces, the nature of globalization in relation to practices in schools, the role of identities-in-practice in relation to participation in communities of practice such as classrooms are explored. Recommendations for key design features in effective science educational spaces, based upon the findings presented in the collection of four studies, are offered. School, it is suggested here, functions best as a clearing house for the myriad science-related stories student participants generate in their various communities of practice (e.g., within popular culture, family, community, informal educational sites). In this way, school has the potential to construct bridges between multiple student experiences and identities-in-practice.

    Climate change poses serious challenges for conservation scientists and policymakers. Yet with these challenges come equally great opportunities to engage communities of concerned citizens in climate science and conservation. National Audubon Society's 2014 Birds and Climate Change report found that 314 North American bird species could lose over half their breeding or wintering ranges by 2080 due to climate change. Consequently, in 2016 Audubon developed two new crowd-sourced science programs that mobilized existing birding communities (i.e., Audubon Society chapters) in partnership with scientists to evaluate climate change effects on birds, and take action to protect vulnerable populations. Climate Watch expands upon traditional monitoring programs by involving citizen scientists in hypothesis-driven science, testing predictions of climate-driven range expansion in bluebirds developed by National Audubon Society scientists. Spoonbill Watch is a partnership between an Audubon research scientist and the Pelican Island Audubon Society community, in which citizen scientists monitor a Roseate Spoonbill colony recently established in response to changing habitat and climatic conditions. Additionally, Spoonbill Watch participants and leaders have moved beyond monitoring to take action to protect the colony, by working with the Florida Fish and Wildlife Conservation Commission towards getting the site declared as a Critical Wildlife Area and by conducting local outreach and education efforts. We will present overviews, lessons learned, and conservation goals and opportunities achieved during the pilot year of Climate Watch and Spoonbill Watch. Scientific - community partnerships such as these are essential to confront the threats posed by climate change.

    Full Text Available In South Africa, polices in higher education are urging tertiary institutions to produce graduates who are socially responsible citizens. One method of achieving this is through service-learning initiatives. Zoos as community partners can provide exciting educational opportunities for students to do animal behaviour studies and to develop their social responsibility. A sample of 58 preservice life-sciences teachers from a South African university completed a questionnaire on their animal behaviour studies. This study sought to determine how animal behaviour studies could successfully be incorporated as a community service-learning project in a zoo setting, what the educational value of these studies was and what the benefits were of incorporating this community service-learning component in the life-sciences course. The incorporation of the service-learning component into the zoology course led to the students’ personal and professional development, knowledge about themselves, sensitivity to cultural diversity, civic responsibility and insights into the ways in which communities operate. For a successful service-learning project, lectures, students and community partners should all have a sense of engagement. A number of suggestions are made to improve the incorporation of this service-learning component into the existing zoology course.

    Full Text Available Children in low and middle-income countries have a high burden of pneumonia. Measuring the cytokine responses may be useful to identify novel markers for diagnosing, monitoring, and treating pneumonia.To describe and compare a wide range of inflammatory mediators in plasma from children with WHO-defined severe and non-severe community acquired pneumonia (CAP, and explore to what extent certain mediators are associated with severity and viral detection.We collected blood samples from 430 children with severe (n = 43 and non-severe (n = 387 CAP. Plasma from these children were analysed for 27 different cytokines, and we measured the association with age, disease severity and viral detection.There were generally higher plasma concentrations of several cytokines with both pro-inflammatory and anti-inflammatory effects among children with severe CAP than in children with non-severe CAP. We found significantly higher concentrations of interleukin (IL-1, IL-4, IL-6, IL-8, IL-9, IL-15, eotaxin, basic fibroblast growth factor (b-FGF, granulocyte colony-stimulating factor (G-CSF, granulocyte-macrophage colony-stimulating factor (GM-CSF, and tumor necrosis factor-alpha (TNF-α in the group of severe CAP. Most of these associations persisted when adjusting for age in linear regression analyses. The cytokine response was strongly associated with age but to a lesser extent with viral etiology.The plasma concentrations of several cytokines, both with pro-inflammatory and anti-inflammatory effects, were higher among children with severe illness. In particular G-CSF and IL-6 reflected severity and might provide complementary information on the severity of the infection.ClinicalTrials.gov NCT00148733.

  2. Iowa community college Science, Engineering and Mathematics (SEM) faculty: Demographics and job satisfaction

    Science.gov (United States)

    Rogotzke, Kathy

    Community college faculty members play an increasingly important role in the educational system in the United States. However, over the past decade, concerns have arisen, especially in several high demand fields of science, technology, engineering and mathematics (STEM), that a shortage of qualified faculty in these fields exists. Furthermore, the average age of community college faculty is increasing, which creates added concern of an increased shortage of qualified faculty due to a potentially large number of faculty retiring. To help further understand the current population of community college faculty, as well as their training needs and their satisfaction with their jobs, data needs to be collected from them and examined. Currently, several national surveys are given to faculty at institutions of higher education, most notably the Higher Education Research Institute Faculty Survey, the National Study of Postsecondary Faculty, and the Community College Faculty Survey of Student Engagement. Of these surveys the Community College Faculty Survey of Student Engagement is the only survey focused solely on community college faculty. This creates a problem because community college faculty members differ from faculty at 4-year institutions in several significant ways. First, qualifications for hiring community college faculty are different at 4-year colleges or universities. Whereas universities and colleges typically require their faculty to have a Ph.D., community colleges require their arts and science faculty to have a only master's degree and their career faculty to have experience and the appropriate training and certification in their field with only a bachelor's degree. The work duties and expectations for community college faculty are also different at 4-year colleges or universities. Community college faculty typically teach 14 to 19 credit hours a semester and do little, if any research, whereas faculty at 4-year colleges typically teach 9 to 12 credit

    Full Text Available In this paper we describe eBird, a highly successful citizen science project. With over 150,000 participants worldwide and an accumulation of over 140,000,000 bird observations globally in the last decade, eBird has evolved into a major tool for scientific investigations in diverse fields such as ornithology, computer science, statistics, ecology and climate change. eBird’s impact in scientific research is grounded in careful data curation practices that pay attention to all stages of the data lifecycle, and attend to the needs of stakeholders engaged in that data lifecycle. We describe the important aspects of eBird, paying particular attention to the mechanisms to improve data quality; describe the data products that are available to the global community; investigate some aspects of the downloading community; and demonstrate significant results that derive from the use of openly-available eBird data.

    classes of students have engaged in and contributed data to science investigations. In Alaska, classes and individual students have conducted their own inquiry studies and have successfully presented their investigations and competed at science fairs and statewide high school science symposium and international conferences. Two students presented their research investigations at the GLOBE Learning Expedition in Croatia and four students presented their study at the GLOBE Arctic POPs Conference in Sweden. These students increased not only their understanding and knowledge of science but also in appreciation of people in other countries and their cultures. Friendships have also bloomed. The learning community in Alaska has expanded to include family and community members including Native elders (using OLCG), teachers, scientists and students from other countries. The following challenges remain: 1) getting funds to be able to provide GLOBE equipment and continuous support to GLOBE teachers and students throughout the year, 2) reaching teachers and students in remote areas, 3) rapid teacher turn-over rate in rural areas, 4) using inquiry-based pedagogies during GLOBE professional development workshops including the opportunity for teacher participants to conduct their own inquiries during the workshop, 5) time, school curriculum and national education requirement constraints, 6) involving school administrators, and more local scientists and community members, and 7) providing culturally relevant and responsive science education programs and life-long learning communities.

  7. Meaningful Engagement in Scientific Practices: How Classroom Communities Develop Authentic Epistemologies for Science

    Science.gov (United States)

    Krist, Christina Rae

    Recent reforms in science education, based on decades of learning research, emphasize engaging students in science and engineering practices as the means to develop and refine disciplinary ideas. These reforms advocate an epistemic shift in how school science is done: from students learning about science ideas to students figuring out core science ideas. This shift is challenging to implement: how do we bring the goals and practices of a discipline into classroom communities in meaningful ways that go beyond simply following rote scientific procedures? In this dissertation, I investigate how classroom communities learn to engage meaningfully in scientific practices, characterizing their engagement as a process of epistemic learning. I take a situated perspective that defines learning as shifts in how members engage in communities of practice. I examine students' epistemic learning as a function of their participation in a classroom community of scientific practice along two dimensions: what they do, or the practical epistemic heuristics they use to guide how they build knowledge; and who they are, or how ownership and authorship of ideas is negotiated and affectively marked through interaction. I focus on a cohort of students as they move from 6th to 8 th grade. I analyze three science units, one from each grade level, to look at the epistemic heuristics implicit in student and teacher talk and how the use of those heuristics shifts over time. In addition, I examine one anomalous 8th grade class to look at how students and the teacher position themselves and each other with respect to the ideas in their classroom and how that positioning supports epistemic learning. Taken together, these analyses demonstrate how students' engagement in scientific practices evolves in terms of what they do and who they are in relation to the knowledge and ideas in their classroom over time. I propose a model for epistemic learning that articulates how classroom communities develop

    We are comparing several non-thermal atmospheric pressure discharge plasmas for life science applications. Here we measured discharge period dependence of pH value and 750 nm absorbance of KI-starch solution of deionized water after plasma irradiation with two discharge devices; a dielectric barrier discharge (DBD) jet device and a scalable DBD device. The pH and the absorbance of KI-starch solution are useful indicator of their oxidizability. We have obtained a map of the absorbance and proton concentration [H+] which is deduced from pH value. For the scalable DBD, the range of the absorbance is between 0.7 and 1.3 and that of [H+] is between 10-7 and 10-5 mol/L. For the DBD jet, the range of the absorbance and [H+] are 2.0-3.2 and 10-4-10-3 mol/L, respectively. Measured data for both devices shows same tendency in the map, while the range of values for the scalable DBD is smaller than that for the DBD jet. The results indicate the oxidazability for the scalable DBD is much weaker than that for the DBD jet.

    2002-01-01

    Full Text Available We describe three interrelated programs in interdisciplinary, undergraduate science education, two at the first-year level and the third an upper-division degree program. They are administered through the Faculty of Science, rather than through individual departments, and are taught by multidisciplinary teams of professors from various departments. In contrast to many programs discussed in the literature, these programs are intended for majors and honors students in all scientific disciplines. They aim to develop transferable skills and a broad outlook on science, in addition to a rigorous foundation in disciplinary knowledge. Interactive engagement and integration of content across disciplines are at the core of the approach. Each program brings together a strong community of scholars that includes students, faculty, staff, and administrators. We explore the benefits of these communities to students and describe the attraction and challenges for the faculty and students who work in them. In that context, we discuss institutional challenges that we faced in creating and sustaining those communities, and in disseminating the ideas on which they are based. In conclusion, we consider the general problem of designing and implementing cross-disciplinary programs.

  10. Self-regulated learning and science achievement in a community college

    Science.gov (United States)

    Maslin, (Louisa) Lin-Yi L.

    Self-regulated learning involves students' use of strategies and skills to adapt and adjust towards achievement in school. This research investigates the extent to which self-regulated learning is employed by community college students, and also the correlates of self-regulated learning: Is it used more by students in advanced science classes or in some disciplines? Is there a difference in the use of it by students who complete a science course and those who do not? How does it relate to GPA and basic skills assessments and science achievement? Does it predict science achievement along with GPA and assessment scores? Community college students (N = 547) taking a science course responded to the Motivated Strategies for Learning Questionnaire (MSLQ). The scales measured three groups of variables: (1) cognitive strategies (rehearsal, elaboration, organization, and critical thinking); (2) metacognitive self-regulation strategies (planning, monitoring, and self-regulation); and (3) resource management strategies (time and study environment, effort regulation, peer learning, and help-seeking). Students' course scores, college GPA, and basic skills assessment scores were obtained from faculty and college records. Students who completed a science course were found to have higher measures on cumulative college GPAs and assessment scores, but not on self-regulated learning. Self-regulated learning was found not to be used differently between students in the advanced and beginning science groups, or between students in different disciplines. The exceptions were that the advanced group scored higher in critical thinking but lower in effort regulation than the beginning group. Course achievement was found to be mostly unrelated to self-regulated learning, except for several significant but very weak and negative relationships in elaboration, self-regulation, help-seeking, and effort regulation. Cumulative GPA emerged as the only significant predictor of science achievement

    Concepts of culture and diversity are necessary considerations in the scientific application of theory generation and developmental processes of preventive interventions; yet, culture and/or diversity are often overlooked until later stages (e.g., adaptation [T3] and dissemination [T4]) of the translational science process. Here, we present a conceptual framework focused on the seamless incorporation of culture and diversity throughout the various stages of the translational science process (T1-T5). Informed by a community-engaged research approach, this framework guides integration of cultural and diversity considerations at each phase with emphasis on the importance and value of "citizen scientists" being research partners to promote ecological validity. The integrated partnership covers the first phase of intervention development through final phases that ultimately facilitate more global, universal translation of changes in attitudes, norms, and systems. Our comprehensive model for incorporating culture and diversity into translational research provides a basis for further discussion and translational science development.

  12. Monkeying around: Examining the effects of a community zoo on the science achievement of third graders

    Science.gov (United States)

    Kenny, Heather A.

    This investigation examined the efficacy of a model of integrated science and literacy instruction situated at a community zoo. Three intact cohorts of third grade urban students received instruction via different treatments: inquiry-based instruction at a zoo; inquiry-based instruction at school; and activity-based instruction at a zoo. All three treatment conditions promoted increased science achievement. There was no difference between the zoo groups at post-test; however the classroom group outperformed both zoo groups. When examined in light of contextual factors (differences in socioeconomic status, teacher level of experience, familiarity of the learning environment), results suggest the effectiveness of the integrated instructional model in promoting increased science achievement. In planning instruction, teachers should consider the novelty of a learning environment, student interest, and how texts can support inquiry.

    Belichesky, Jennifer

    The purpose of this study was to expand on the current research pertaining to women in science, technology, engineering, and mathematics (STEM) majors, better understand the experiences of undergraduate women in the sciences, identify barriers to female persistence in their intended STEM majors, and understand the impact of the STEM co-educational Living Learning Community (LLC) model on female persistence. This study employed a mixed-methods approach that was grounded in standpoint methodology. The qualitative data were collected through focus groups and one-on-one interviews with the female participants and was analyzed through a critical feminist lens utilizing standpoint methodology and coded utilizing inductive analysis. The quantitative data were collected and analyzed utilizing a simple statistical analysis of key academic variables indicative of student success: cumulative high school GPAs, SAT scores, first year cumulative GPAs, freshman persistence patterns in the intended major, and freshman retention patterns at the university. The findings of this study illustrated that the co-educational LLC model created an inclusive academic and social environment that positively impacted the female participants' experiences and persistence in STEM. The findings also found the inclusion of men in the community aided in the demystification of male superiority in the sciences for the female participants. This study also highlighted the significance of social identity in the decision making process to join a science LLC.

    2009-12-01

    NSF-style Broader Impacts activities in the Earth Sciences take many forms, from long term partnerships between universities and informal science institutions to one-time K-12 classroom visits by scientists. Broader Impacts that include K-12 teachers range from those that convey broad Earth Science concepts to others stressing direct connections to very specific current research methods and results. Design of these programs is often informed by prior successful models and a broad understanding of teacher needs, but is not specifically designed to address needs expressed by teachers themselves. In order to better understand teachers’ perceived needs for connections to Earth Science research, we have formed the Science Teaching and Professional Learning in the Earth Sciences (STAPLES) research team. Our team includes a geology faculty member experienced in undergraduate and professional Earth Science teacher training, two in-service middle school Earth Science teachers, and the Education Director of the National Center for Earth-surface Dynamics (NCED), a National Science Foundation Science and Technology Center. Members of the team have designed, taught and experienced many of these models, from the Andrill ARISE program to NCED’s summer institutes and teacher internship program. We are administering the STAPLES survey to ask Earth Science teachers in our own state (Minnesota) which of many models they use to 1) strengthen their own understanding of current Earth Science research and general Earth Science concepts and 2) deepen their students’ understanding of Earth Science content. Our goal is to share survey results to inform more effective Broader Impacts programs in Minnesota and to stimulate a wider national discussion of effective Broader Impacts programs that includes teachers’ voices.

  15. Linking adaptation science to action to build food secure Pacific Island communities

    2016-01-01

    Full Text Available Climate change is a major threat to food security in Pacific Island countries, with declines in food production and increasing variability in food supplies already evident across the region. Such impacts have already led to observed consequences for human health, safety and economic prosperity. Enhancing the adaptive capacity of Pacific Island communities is one way to reduce vulnerability and is underpinned by the extent to which people can access, understand and use new knowledge to inform their decision-making processes. However, effective engagement of Pacific Island communities in climate adaption remains variable and is an ongoing and significant challenge. Here, we use a qualitative research approach to identify the impediments to engaging Pacific Island communities in the adaptations needed to safeguard food security. The main barriers include cultural differences between western science and cultural knowledge, a lack of trust among local communities and external scientists, inappropriate governance structures, and a lack of political and technical support. We identify the importance of adaptation science, local social networks, key actors (i.e., influential and trusted individuals, and relevant forms of knowledge exchange as being critical to overcoming these barriers. We also identify the importance of co-ordination with existing on-ground activities to effectively leverage, as opposed to duplicating, capacity.

    The study of coupled natural and human systems in a changing world can benefit greatly from indigenous perspectives, which have the potential to bring deep, placed-based understanding to complex environmental issues while promoting sustainable solutions to pressing socio-environmental problems. In recent years, scientists have begun to embrace indigenous knowledge and perspectives, but indigenous voices in the sciences remain relatively few. At the same time, indigenous communities face wide ranging and unique vulnerabilities to global environmental change on a variety of fronts, particularly where water resources are concerned. Given this situation, indigenous scientists often find themselves bridging both western scientific and indigenous communities, sometimes embodying the nexus in a literal sense. Here I reflect on this nexus from the perspective of an indigenous hydrologist collaborating with American Indian communities in North Carolina, which has the largest American Indian population of any state in the eastern US. Intertwining case studies of coupled natural and human systems illustrate some of the the challenges, complexities, and successes of ongoing collaborations with tribal communities and Native-serving organizations on water resource issues, environmental impacts of food and energy production, and broadening participation of American Indians in the sciences.

  17. (De)colonizing culture in community psychology: reflections from critical social science.

    Reyes Cruz, Mariolga; Sonn, Christopher C

    2011-03-01

    Since its inception, community psychology has been interested in cultural matters relating to issues of diversity and marginalization. However, the field has tended to understand culture as static social markers or as the background for understanding group differences. In this article the authors contend that culture is inseparable from who we are and what we do as social beings. Moreover, culture is continually shaped by socio-historical and political processes intertwined within the globalized history of power. The authors propose a decolonizing standpoint grounded in critical social science to disrupt understandings of cultural matters that marginalize others. This standpoint would move the field toward deeper critical thinking, reflexivity and emancipatory action. The authors present their work to illustrate how they integrate a decolonizing standpoint to community psychology research and teaching. They conclude that community psychology must aim towards intercultural work engaging its political nature from a place of ontological/epistemological/methodological parity.

    2010-12-01

    In February, 2010, the University of California - San Diego's long simmering racism crisis erupted in response to a series of racist provocations, including a fraternity party titled "The Compton Cookout" and a noose discovered in the main library. Student groups led by the Black Student Union organized a series of protests, occupations and discussions highlighting the situation at UCSD (including the low fraction of African American students: 1.3%), and pressuring the university to take action. Extensive interviews (March-May, 2010) with participants in the protests indicate that most felt the UCSD senior administration's response was inadequate and failed to address the underlying causes of the crisis. In an attempt to contribute to a more welcoming university that connects to working class communities of color, we have developed an educational program directed towards students in the environmental- and geo-sciences that seeks to establish genuine, two-way links between students and working people, with a focus on City Heights, a multi-ethnic, multi-lingual diverse immigrant community 20 miles from UCSD. Elements of the program include: --critiquing research universities and their connection to working class communities --learning about and discussing issues affecting City Heights, including community, environmental racism, health and traditional knowledge; --interviewing organizers and activists to find out about the stories and struggles of the community; --working on joint projects affecting environmental quality in City Heights with high school students; --partnering with individual high school students to develop a proposal for a joint science project of mutual interest; --developing a proposal for how UCSD could change to better interface with City Heights. An assessment of the impact of the program on individual community members and UCSD students and on developing enduring links between City Heights and UCSD will be presented followed by a preliminary

    Environmental health research involving community participation has increased substantially since the National Institute of Environmental Health Sciences (NIEHS) environmental justice and community-based participatory research (CBPR) partnerships began in the mid-1990s. The goals of these partnerships are to inform and empower better decisions about exposures, foster trust, and generate scientific knowledge to reduce environmental health disparities in low-income, minority communities. Peer-reviewed publication and clinical health outcomes alone are inadequate criteria to judge the success of projects in meeting these goals; therefore, new strategies for evaluating success are needed. We reviewed the methods used to evaluate our project, "Linking Breast Cancer Advocacy and Environmental Justice," to help identify successful CBPR methods and to assist other teams in documenting effectiveness. Although our project precedes the development of the NIEHS Evaluation Metrics Manual, a schema to evaluate the success of projects funded through the Partnerships in Environmental Public Health (PEPH), our work reported here illustrates the record keeping and self-reflection anticipated in NIEHS's PEPH. Evaluation strategies should assess how CBPR partnerships meet the goals of all partners. Our partnership, which included two strong community-based organizations, produced a team that helped all partners gain organizational capacity. Environmental sampling in homes and reporting the results of that effort had community education and constituency-building benefits. Scientific results contributed to a court decision that required cumulative impact assessment for an oil refinery and to new policies for chemicals used in consumer products. All partners leveraged additional funding to extend their work. An appropriate evaluation strategy can demonstrate how CBPR projects can advance science, support community empowerment, increase environmental health literacy, and generate

    Despite there being well-established meteorological and hydrometric monitoring networks in the UK, many smaller catchments remain ungauged. This leaves a challenge for characterisation, modelling, forecasting and management activities. Here we demonstrate the value of community-based ('citizen science') observations for modelling and understanding catchment response as a contribution to catchment science. The scheme implemented within the 42 km2 Haltwhistle Burn catchment, a tributary of the River Tyne in northeast England, has harvested and used quantitative and qualitative observations from the public in a novel way to effectively capture spatial and temporal river response. Community-based rainfall, river level and flood observations have been successfully collected and quality-checked, and used to build and run a physically-based, spatially-distributed catchment model, SHETRAN. Model performance using different combinations of observations is tested against traditionally-derived hydrographs. Our results show how the local network of community-based observations alongside traditional sources of hydro-information supports characterisation of catchment response more accurately than using traditional observations alone over both spatial and temporal scales. We demonstrate that these community-derived datasets are most valuable during local flash flood events, particularly towards peak discharge. This information is often missed or poorly represented by ground-based gauges, or significantly underestimated by rainfall radar, as this study clearly demonstrates. While community-based observations are less valuable during prolonged and widespread floods, or over longer hydrological periods of interest, they can still ground-truth existing traditional sources of catchment data to increase confidence during characterisation and management activities. Involvement of the public in data collection activities also encourages wider community engagement, and provides important

    2006-07-01

    A strong science knowledge base and problem solving skills have always been highly valued for employment in the science industry. Skills currently needed for employment include being able to problem solve (Overtoom, 2000). Academia also recognizes the need for effectively teaching students to apply problem solving skills in clinical settings. This thesis investigates how students solve complex science problems in an academic setting in order to inform the development of problem solving skills for the workplace. Students' use of problem solving skills in the form of learned concepts and procedural knowledge was studied as students completed a problem that might come up in real life. Students were taking a community college sophomore biology course, Human Anatomy & Physiology II. The problem topic was negative feedback inhibition of the thyroid and parathyroid glands. The research questions answered were (1) How well do community college students use a complex of conceptual knowledge when solving a complex science problem? (2) What conceptual knowledge are community college students using correctly, incorrectly, or not using when solving a complex science problem? (3) What problem solving procedural knowledge are community college students using successfully, unsuccessfully, or not using when solving a complex science problem? From the whole class the high academic level participants performed at a mean of 72% correct on chapter test questions which was a low average to fair grade of C-. The middle and low academic participants both failed (F) the test questions (37% and 30% respectively); 29% (9/31) of the students show only a fair performance while 71% (22/31) fail. From the subset sample population of 2 students each from the high, middle, and low academic levels selected from the whole class 35% (8/23) of the concepts were used effectively, 22% (5/23) marginally, and 43% (10/23) poorly. Only 1 concept was used incorrectly by 3/6 of the students and identified as

    Methods used by researchers to track science events during a science research cruise - and to note when and where these occur - varies widely. Handwritten notebooks, printed forms, watch-keeper logbooks, data-logging software, and customized software have all been employed. The quality of scientific results is affected by the consistency and care with which such events are recorded and integration of multi-cruise results is hampered because recording methods vary widely from cruise to cruise. The Rolling Deck to Repository (R2R) program has developed an Eventlogger system that will eventually be deployed on most vessels in the academic research fleet. It is based on the open software package called ELOG (http://midas.psi.ch/elog/) originally authored by Stefan Ritt and enhanced by our team. Lessons have been learned in its development and use on several research cruises. We have worked hard to find approaches that encourage cruise participants to use tools like the eventlogger. We examine these lessons and several eventlogger datasets from past cruises. We further describe how the R2R Science Eventlogger works in concert with the other R2R program elements to help coordinate research vessels into a coordinated mobile observing fleet. Making use of data collected on different research cruises is enabled by adopting common ways of describing science events, the science instruments employed, the data collected, etc. The use of controlled vocabularies and the practice of mapping these local vocabularies to accepted oceanographic community vocabularies helps to bind shipboard research events from different cruises into a more cohesive set of fleet-wide events that can be queried and examined in a cross-cruise manner. Examples of the use of the eventlogger during multi-cruise oceanographic research programs along with examples of resultant eventlogger data will be presented. Additionally we will highlight the importance of vocabulary use strategies to the success of the

    A critical part of effective Earth science data and information system interoperability involves collaboration across geographically and temporally distributed communities. The Federation of Earth Science Information Partners (ESIP) is a broad-based, distributed community of science, data and information technology practitioners from across science domains, economic sectors and the data lifecycle. ESIP's open, participatory structure provides a melting pot for coordinating around common areas of interest, experimenting on innovative ideas and capturing and finding best practices and lessons learned from across the network. Since much of ESIP's work is distributed, the Foundation for Earth Science was established as a non-profit home for its supportive collaboration infrastructure. The infrastructure leverages the Internet and recent advances in collaboration web services. ESIP provides neutral space for self-governed groups to emerge around common Earth science data and information issues, ebbing and flowing as the need for them arises. As a group emerges, the Foundation quickly equips the virtual workgroup with a set of ';commodity services'. These services include: web meeting technology (Webex), a wiki and an email listserv. WebEx allows the group to work synchronously, dynamically viewing and discussing shared information in real time. The wiki is the group's primary workspace and over time creates organizational memory. The listserv provides an inclusive way to email the group and archive all messages for future reference. These three services lower the startup barrier for collaboration and enable automatic content preservation to allow for future work. While many of ESIP's consensus-building activities are discussion-based, the Foundation supports an ESIP testbed environment for exploring and evaluating prototype standards, services, protocols, and best practices. After community review of testbed proposals, the Foundation provides small seed funding and a

    Despite significant advancements in the scientific evidence base of interventions to improve newborn survival, we have not yet been able to "bend the curve" to markedly accelerate global rates of reduction in newborn mortality. The ever-widening gap between discovery of scientific best practices and their mass adoption by families (the evidence-practice gap) is not just a matter of improving the coverage of health worker-community interactions. The design of the interactions themselves must be guided by sound behavioral science approaches such that they lead to mass adoption and impact at a large scale. The main barrier to the application of scientific approaches to behavior change is our inability to "unbox" the "black box" of family health behaviors in community settings. The authors argue that these are not black boxes, but in fact thoughtfully designed community systems that have been designed and upheld, and have evolved over many years keeping in mind a certain worldview and a common social purpose. An empathetic understanding of these community systems allows us to deconstruct the causal pathways of existing behaviors, and re-engineer them to achieve desired outcomes. One of the key reasons for the failure of interactions to translate into behavior change is our failure to recognize that the content, context, and process of interactions need to be designed keeping in mind an organized community system with a very different worldview and beliefs. In order to improve the adoption of scientific best practices by communities, we need to adapt them to their culture by leveraging existing beliefs, practices, people, context, and skills. The authors present a systems approach for community-centric design of interactions, highlighting key principles for achieving intrinsically motivated, sustained change in social norms and family health behaviors, elucidated with progressive theories from systems thinking, management sciences, cross-cultural psychology, learning

    Hutt, Chris D.

    The purpose of this study was to explore the articulated experiences of natural science majors who were participating in a liberal arts living-learning community. Using the American Association of College and University's (2002) report, Greater Expectations as an organizing framework, this study sought to determine how - if at all - students in this learning community were encountering the organizational educational principles consistent with classical and contemporary liberal education. The study was a qualitative inquiry that examined students' precollege experiences and beliefs, their current perceptions on their academic experiences, and student reflections on the meaning of these experiences. The data collected and analyzed in the completion of this study consisted of a series of 19 individual interviews with students enrolled in both a natural science major and in a living- learning community (LLC). Analysis of the interview data led the researcher to identify four themes: (a) Students attributed intellectual growth to experiences in both the major and the LLC, and that the science curriculum was in some ways separated from the liberal arts curriculum; (b) Students experienced and defined diversity in meaningful ways; (c) Physical place and social space of the LLC contributed significantly to the program; and (d) Students reflected learning experiences and outcomes consistent with both classical and contemporary liberal educational environments. Ultimately, the students in this study viewed their participation in the LLC as a meaningful supplement to the science major. Further analysis of the findings, as well as conclusions and recommendations for both policy and practice, are discussed in the final chapter of the study.

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

  9. Lesson Study-Building Communities of Learning Among Pre-Service Science Teachers

    Science.gov (United States)

    Hamzeh, Fouada

    Lesson Study is a widely used pedagogical approach that has been used for decades in its country of origin, Japan. It is a teacher-led form of professional development that involves the collaborative efforts of teachers in co-planning and observing the teaching of a lesson within a unit for evidence that the teaching practices used help the learning process (Lewis, 2002a). The purpose of this research was to investigate if Lesson Study enables pre-service teachers to improve their own teaching in the area of science inquiry-based approaches. Also explored are the self-efficacy beliefs of one group of science pre-service teachers related to their experiences in Lesson Study. The research investigated four questions: 1) Does Lesson Study influence teacher preparation for inquiry-based instruction? 2) Does Lesson Study improve teacher efficacy? 3) Does Lesson Study impact teachers' aspiration to collaborate with colleagues? 4) What are the attitudes and perceptions of pre-service teachers to the Lesson Study idea in Science? The 12 participants completed two pre- and post-study surveys: STEBI- B, Science Teaching Efficacy Belief Instrument (Enochs & Riggs, 1990) and ASTQ, Attitude towards Science Teaching. Data sources included student teaching lesson observations, lesson debriefing notes and focus group interviews. Results from the STEBI-B show that all participants measured an increase in efficacy throughout the study. This study added to the body of research on teaching learning communities, professional development programs and teacher empowerment.

    The Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) is a non-profit funded by the National Science Foundation to support water science research and education. As outlined in the CUAHSI Education and Outreach Strategy, our objectives are: 1) helping the member institutions communicate water science; 2) cross-disciplinary water education; 3) dissemination of research; 4) place-based water education using data services; and 5) broadening participation. Through the CUAHSI Water Data Center, online tools and resources are available to discover, download, and analyze multiple time-series water datasets across various parameters. CUAHSI supports novel graduate student research through the Pathfinder Fellowship program which has enhanced the interdisciplinary breadth of early-career research. Public outreach through the Let's Talk About Water film symposium and cyberseminar programs have proven effective in distributing research, leading to more recent development of virtual training workshops. By refining and building upon CUAHSI's existing programs, new training opportunities, collaborative projects, and community-building activities for the hydrologic sciences have come to fruition, such as the recent National Flood Interoperability Experiment with the NOAA's National Water Center.

    We applied a new approach to the design and development of citizen science learning opportunities to enhance outreach to diverse student populations, while advancing water quality research and aerospace education. This collaborative approach to informal science, technology, engineering, and math (STEM) and aerospace education required innovative partnerships between private general aviation pilots, researchers, teachers, and students. This research explored the development of active partnerships required to facilitate community engaged science, with an emphasis on increased participation of women and girls and people of color, while creating new exploratory pathways for broadening access to and engagement in STEM learning experiences. We developed an outreach program through collaborative planning with local schools to create new STEM learning experiences based upon basic aerospace education concepts and an existing water quality research project designed to track harmful algal blooms (HAB) that can produce toxins called cyanobacteria, also known as blue-green algae, which can impact drinking, fishing, and recreational waters. General aviation pilots functioning as citizen scientists obtained high-resolution aerial images while flying over potentially impacted waters. Aerial data was made available to teachers and students, as well as researchers participating in the existing water quality program lead by NASA Glenn Research Center. Teachers used the images and results to educate in climate change and the dangers of HAB. Students were able to compare aerial data with their own observations, and also gained experience in aeronautical science through field trips to local airports, hands-on experience with private research aircraft, specialized equipment used for data collection, and advanced ground instruction from research pilots. As a result of reaching out to local educators serving diverse student populations and facilitating collaborative planning, we

    Data Science is described as the process of knowledge extraction from large data sets by means of scientific methods. The discipline draws heavily from techniques and theories from many fields, which are jointly used to furthermore develop information retrieval on structured or unstructured very large datasets. While the term Data Science was already coined in 1960, the current perception of this field places is still in the first section of the hype cycle according to Gartner, being well en route from the technology trigger stage to the peak of inflated expectations. In our view the future development of Data Science could benefit from the analysis of experiences from related evolutionary processes. One predecessor is the area of Geographic Information Systems (GIS). The intrinsic scope of GIS is the integration and storage of spatial information from often heterogeneous sources, data analysis, sharing of reconstructed or aggregated results in visual form or via data transfer. GIS is successfully applied to process and analyse spatially referenced content in a wide and still expanding range of science areas, spanning from human and social sciences like archeology, politics and architecture to environmental and geoscientific applications, even including planetology. This paper presents proven patterns for innovation and organisation derived from the evolution of GIS, which can be ported to Data Science. Within the GIS landscape, three strategic interacting tiers can be denoted: i) Standardisation, ii) applications based on closed-source software, without the option of access to and analysis of the implemented algorithms, and iii) Free and Open Source Software (FOSS) based on freely accessible program code enabling analysis, education and ,improvement by everyone. This paper focuses on patterns gained from the synthesis of three decades of FOSS development. We identified best-practices which evolved from long term FOSS projects, describe the role of community

  13. Training in the laboratory animal science community: strategies to support adult learning.

    The essence of learning is change; learning is the process by which learners customize new information to make it personally meaningful and relevant. Training is the process of helping students make those changes. Research indicates that adults learn differently than children or adolescents and that adults consistently use the following six learning strategies: prior experiences; conversations; metacognition; reflection; authentic experiences; and images, pictures, or other types of visuals. Each of these learning strategies can be combined with the other strategies and often build upon each other. A recent study on how health care professionals learn indicated that the learning strategy they used most often was reflection, which supports learning before, during, and after training. Numerous examples are provided in this article describing how to integrate each of the six adult learning strategies into laboratory animal science training. While lectures and other types of direct instruction are appropriate, they are inadequate and ineffective unless they are integrated with and support adult learning strategies. Both the US Department of Agriculture regulations and the Public Health Service Policy mandate that research institutions must ensure that all personnel involved in animal care, treatment, or use are qualified to perform their duties. Applying adult learning strategies to training for the laboratory animal science community will enhance learning and improve both the science and the humane care of the animals, which is a goal our community must continuously strive to achieve.

    The James Webb Space Telescope (JWST) will likely revolutionize transiting exoplanet atmospheric science; however, it is unclear precisely how well it will perform and which of its myriad instruments and observing modes will be best suited for transiting exoplanet studies. We will describe a prefatory JWST Early Release Science (ERS) Cycle 1 program that focuses on testing specific observing modes to quickly give the community the data and experience it needs to plan more efficient and successful transiting exoplanet characterization programs in later cycles. We will also present a list of "community targets" that are well suited to achieving these goals. Since most of the community targets do not have well-characterized atmospheres, we have initiated a preparatory HST + Spitzer observing program to determine the presence of obscuring clouds/hazes within their atmospheres. Measurable spectroscopic features are needed to establish the optimal resolution and wavelength regions for exoplanet characterization. We will present preliminary results from this preparatory observing program and discuss their implications on the pending JWST ERS proposal deadline in mid-2017.

    Wendt, Jillian Leigh

    This study examines the effects of online collaborative learning on middle school students' science literacy and sense of community. A quantitative, quasi-experimental pretest/posttest control group design was used. Following IRB approval and district superintendent approval, students at a public middle school in central Virginia completed a pretest consisting of the Misconceptions-Oriented Standards-Based Assessment Resources for Teachers (MOSART) Physical Science assessment and the Classroom Community Scale. Students in the control group received in-class assignments that were completed collaboratively in a face-to-face manner. Students in the experimental group received in-class assignments that were completed online collaboratively through the Edmodo educational platform. Both groups were members of intact, traditional face-to-face classrooms. The students were then post tested. Results pertaining to the MOSART assessment were statistically analyzed through ANCOVA analysis while results pertaining to the Classroom Community Scale were analyzed through MANOVA analysis. Results are reported and suggestions for future research are provided.

  16. Communities of practice: Participation patterns and professional impact for high school mathematics and science teachers

    Science.gov (United States)

    Printy, Susan M.

    Improving the quality of teachers in schools is a keystone to educational improvement. New and veteran teachers alike need to enhance their content knowledge and pedagogical skills, but they must also examine, and often change, their underlying attitudes, beliefs, and values about the nature of knowledge and the abilities of students. Best accomplished collectively rather than individually, the interactions between teachers as they undertake the process of collaborative inquiry create "communities of practice." This dissertation investigates the importance of science and mathematics teachers' participation in communities of practice to their professional capabilities. The study tests the hypothesis that the social learning inherent in community of practice participation encourages teachers to learn from others with expertise, enhances teachers' sense of competence, and increases the likelihood that teachers' will use student-centered, problem-based instructional techniques aligned with national disciplinary standards. The researcher conceptualizes communities of practice along two dimensions that affect social learning: legitimate participation in activities and span of engagement with school members. Differences in teachers' subject area and the curricular track of their teaching assignment contribute to variation in teachers' participation in communities of practice along those dimensions. Using data from the National Educational Longitudinal Study, first and second follow-up, the study has two stages of multi-level analysis. The first stage examines factors that contribute to teachers' participation in communities of practice, including teachers' social and professional characteristics and school demographic and organizational characteristics. The second stage investigates the professional impact of such participation on the three outcome variables: teacher learning, teacher competence, and use of standards-based pedagogy.

    Low temperature plasma science (LTPS) is a field on the verge of an intellectual revolution. Partially ionized plasmas (often referred to as gas discharges) are used for an enormous range of practical applications, from light sources and lasers to surgery and making computer chips, among many others. The commercial and technical value of low temperature plasmas (LTPs) is well established. Modern society would simply be less advanced in the absence of LTPs. Much of this benefit has resulted from empirical development. As the technology becomes more complex and addresses new fields, such as energy and biotechnology, empiricism rapidly becomes inadequate to advance the state of the art. The focus of this report is that which is less well understood about LTPs - namely, that LTPS is a field rich in intellectually exciting scientific challenges and that addressing these challenges will result in even greater societal benefit by placing the development of plasma technologies on a solid science foundation. LTPs are unique environments in many ways. Their nonequilibrium and chemically active behavior deviate strongly from fully ionized plasmas, such as those found in magnetically confined fusion or high energy density plasmas. LTPs are strongly affected by the presence of neutral species-chemistry adds enormous complexity to the plasma environment. A weakly to partially ionized gas is often characterized by strong nonequilibrium in the velocity and energy distributions of its neutral and charged constituents. In nonequilibrium LTP, electrons are generally hot (many to tens of electron volts), whereas ions and neutrals are cool to warm (room temperature to a few tenths of an electron volt). Ions and neutrals in thermal LTP can approach or exceed an electron volt in temperature. At the same time, ions may be accelerated across thin sheath boundary layers to impact surfaces, with impact energies ranging up to thousands of electron volts. These moderately energetic electrons

    2007-12-01

    Science research courses have been around for years at the university and high school level. As inquiry based learning has become more and more a part of the science teacher's vocabulary, many of these courses have adopted an inquiry model for studying science. Learners of all ages benefit from learning through the natural process of inquiry. I participated in the CIRES Earthworks program for science teachers (Colorado University) in the summer of 2007 and experienced, first hand, the value of inquiry learning. With the support and vision of my school administration, and with the support and commitment of community partners, I have developed a Middle School Science Research Program that is transforming how science is taught to students in my community. Swift Creek Middle School is located in Tallahassee, Florida. There are approximately 1000 students in this suburban public school. Students at Swift Creek are required to take one science class each year through 8th grade. As more emphasis is placed on learning a large number of scientific facts and information, in order to prepare students for yearly, standardized tests, there is a concern that less emphasis may be placed on the process and nature of science. The program I developed draws from the inquiry model followed at the CIRES Earthworks program, utilizes valuable community partnerships, and plays an important role in meeting that need. There are three major components to this Middle School Research Program, and the Center for Integrated Research and Learning (CIRL) at the National High Magnetic Field Lab (NHMFL) at Florida State University is playing an important role in all three. First, each student will develop their own research question and design experiments to answer the question. Scientists from the NHMFL are serving as mentors, or "buddy scientists," to my students as they work through the process of inquiry. Scientists from the CIRES - Earthworks program, Florida State University, and other

    The James Webb Space Telescope will revolutionize transiting exoplanet atmospheric science due to its capability for continuous, long-duration observations and its larger collecting area, spectral coverage, and spectral resolution compared to existing space-based facilities. However, it is unclear precisely how well JWST will perform and which of its myriad instruments and observing modes will be best suited for transiting exoplanet studies. In this article, we describe a prefatory JWST Early Release Science (ERS) program that focuses on testing specific observing modes to quickly give the community the data and experience it needs to plan more efficient and successful future transiting exoplanet characterization programs. We propose a multi-pronged approach wherein one aspect of the program focuses on observing transits of a single target with all of the recommended observing modes to identify and understand potential systematics, compare transmission spectra at overlapping and neighboring wavelength regions...

    The Council on Undergraduate Research (CUR) is a professional organization dedicated to strengthening science and undergraduate science education. Central to the activities and programs sponsored by CUR is the recognition that the investigative process, especially undergraduate student research, plays a key role in an undergraduate science education. Publications, conferences, and other activities of CUR have facilitated the establishment and maintenance of a network of undergraduate teacher-researchers. For many members, myself included, the most important aspect of CUR is this sense of community provided by the opportunities to meet and work with colleagues who hold shared values and common expectations for science education. First established by a small group of prominent chemistry faculty in 1978, the Council on Undergraduate Research is now a rapidly growing multidisciplinary organization serving over 3,500 members in seven scientific and mathematical divisions, including biology, chemistry, geology, physics/astronomy, mathematics, and psychology (Fig. 1.). Chemists continue to play an important role in CUR; the Division of Chemistry, with more than 1,200 members, is the largest division.

    Generating the capacity to facilitate the informed usage of climate change science by decision makers on a large scale is fast becoming an area of great concern. While research demonstrates that sustained interactions between producers of such information and potential users can overcome barriers to information usage, it also demonstrates the high resource demand of these efforts. Our social science work at Great Lakes Integrated Sciences and Assessments (GLISA) sheds light on scaling up the usability of climate science through two research areas. The first focuses on partnerships with other boundary organizations that GLISA has leveraged - the "boundary chains" approach. These partnerships reduce the transaction costs involved with outreach and have enhanced the scope of GLISA's climate service efforts to encompass new users such as First Nations groups in Wisconsin and Michigan and underserved neighborhoods in St. Paul, Minnesota. The second research area looks at the development of information usability across the regional scale of the eight Great Lakes states. It has identified the critical role that communities of practice are playing in making information usable to large groups of users who work in similar contexts and have similar information needs. Both these research areas demonstrate the emerging potential of flexible knowledge networks to enhance society's ability to prepare for the impacts of climate change.

    Contributing to an emerging field of social science literature by examining the translation of genomic medicine across global and transnational fields of research and medicine, this article examines how genetics is allied to public health in Cuba. It examines the sociopolitical and cultural discourses and practices that constitute community genetics or challenge or impede the translation and expansion of genomics as public health. Focusing on the experience of health practitioners, the article explores how their work is circumscribed by cultural values and social ideologies that collectively reveal an unexpected heterogeneity in how genetics is being constituted and reproduced. Although the Western quest for genomics as "personal medicine" is revealed here as both ideologically and practically problematic, such challenges paradoxically work to reinforce a commitment to maintaining the distinctive field of Cuban community genetics in its orientation to collective public health.

    Why should scientists incorporate education and extend communicate the results of their research to the general public? - Because it is the right thing to do; it is easy, fun and usually effective; can feedback to strengthen and improve research; and from an environmental science perspective - badly needed as evidenced by some of the very strange and ill-informed decisions society is making that will affect future generations for many years to come. This presentation focuses on two case studies that extended the research activities from a relatively young and small university research lab to two minority student and community audiences. The first case study focuses on the educational and outreach experience gained by minority graduate and undergraduate students and teachers participating in an Antarctic system Science study abroad course. Students completed an online class, visited with NSF and other federal agencies in Washington DC, and experienced Patagonia and the Antarctic Peninsula on a month long capstone field course. Participants also visited the classrooms of over 750 students in El Paso, Texas before and after their trip to Antarctica, and prepared a museum exhibit that has now been visited by thousands of people. Most participants have progressed to graduate school or careers in the sciences and several have already acquired substantial funding for research - largely because of their demonstrated capacity to link research, education and outreach. The second case study describes several instances where the provision of scientific data, information and other resources were extended through cyberinfrastructure to the community of a relatively small Inuit village in northernmost Alaska. Here science data products have been used to enhance town planning and other decision making, and improve the safety of hunters participating in traditional activities such as the Spring subsistence whale harvest. This takes place on sea ice that is more dynamic and does not

    Full Text Available A citizen-science study was conducted in two low-income, flood-prone communities in Atlanta, Georgia, in order to document environmental exposures and the prevalence of occupant asthma. Teams consisting of a public-health graduate student and a resident from one of the two communities administered a questionnaire, inspected residences for mold growth, and collected a dust sample for quantifying mold contamination. The dust samples were analyzed for the 36 molds that make up the Environmental Relative Moldiness Index (ERMI. Most residents (76% were renters. The median duration of residence was 2.5 years. Although only 12% of occupants reported a history of flooding, 46% reported at least one water leak. Homes with visible mold (35% had significantly (P<0.05 higher mean ERMI values compared to homes without (14.0 versus 9.6. The prevalence of self-reported, current asthma among participants was 14%. In logistic regression models controlling for indoor smoking, among participants residing at their current residence for two years or less, a positive association was observed between asthma and the homes’ ERMI values (adjusted odds ratio per unit increase in ERMI = 1.12, 95% confidence intervals (CI: 1.01–1.25; two-tailed P=0.04. Documentation of the exposures and asthma prevalence has been presented to the communities and public officials. Community-based organizations have taken responsibility for planning and implementing activities in response to the study findings.

    Deep Carbon Observatory (DCO) is a decade-long scientific endeavor to understand carbon in the complex deep Earth system. Thousands of DCO scientists from institutions across the globe are organized into communities representing four domains of exploration: Extreme Physics and Chemistry, Reservoirs and Fluxes, Deep Energy, and Deep Life. Cross-community and cross-disciplinary collaboration is one of the most distinctive features in DCO's flexible research framework. VIVO is an open-source Semantic Web platform that facilitates cross-institutional researcher and research discovery. it includes a number of standard ontologies that interconnect people, organizations, publications, activities, locations, and other entities of research interest to enable browsing, searching, visualizing, and generating Linked Open (research) Data. The DCO-VIVO solution expedites research collaboration between DCO scientists and communities. Based on DCO's specific requirements, the DCO Data Science team developed a series of extensions to the VIVO platform including extending the VIVO information model, extended query over the semantic information within VIVO, integration with other open source collaborative environments and data management systems, using single sign-on, assigning of unique Handles to DCO objects, and publication and dataset ingesting extensions using existing publication systems. We present here the iterative development of these requirements that are now in daily use by the DCO community of scientists for research reporting, information sharing, and resource discovery in support of research activities and program management.

  7. Influence of Precollege Experience on Self-Concept among Community College Students in Science, Mathematics, and Engineering

    Starobin, Soko S.; Laanan, Frankie Santos

    Female and minority students have historically been underrepresented in the field of science, mathematics, and engineering at colleges and universities. Although a plethora of research has focused on students enrolled in 4-year colleges or universities, limited research addresses the factors that influence gender differences in community college students in science, mathematics, and engineering. Using a target population of 1,599 aspirants in science, mathematics, and engineering majors in public community colleges, this study investigates the determinants of self-concept by examining a hypothetical structural model. The findings suggest that background characteristics, high school academic performance, and attitude toward science have unique contributions to the development of self-concept among female community college students. The results add to the literature by providing new theoretical constructs and the variables that predict students' self-concept.

    This report summarizes the work of the National Fusion Collaboratory (NFC) Project funded by the United States Department of Energy (DOE) under the Scientific Discovery through Advanced Computing Program (SciDAC) to develop a persistent infrastructure to enable scientific collaboration for magnetic fusion research. A five year project that was initiated in 2001, it built on the past collaborative work performed within the U.S. fusion community and added the component of computer science research done with the USDOE Office of Science, Office of Advanced Scientific Computer Research. The project was a collaboration itself uniting fusion scientists from General Atomics, MIT, and PPPL and computer scientists from ANL, LBNL, Princeton University, and the University of Utah to form a coordinated team. The group leveraged existing computer science technology where possible and extended or created new capabilities where required. Developing a reliable energy system that is economically and environmentally sustainable is the long-term goal of Fusion Energy Science (FES) research. In the U.S., FES experimental research is centered at three large facilities with a replacement value of over $1B. As these experiments have increased in size and complexity, there has been a concurrent growth in the number and importance of collaborations among large groups at the experimental sites and smaller groups located nationwide. Teaming with the experimental community is a theoretical and simulation community whose efforts range from applied analysis of experimental data to fundamental theory (e.g., realistic nonlinear 3D plasma models) that run on massively parallel computers. Looking toward the future, the large-scale experiments needed for FES research are staffed by correspondingly large, globally dispersed teams. The fusion program will be increasingly oriented toward the International Thermonuclear Experimental Reactor (ITER) where even now, a decade before operation begins, a large

  9. Building professional identity as computer science teachers: Supporting high school computer science teachers through reflection and community building

    Ni, Lijun

    Computing education requires qualified computing teachers. The reality is that too few high schools in the U.S. have computing/computer science teachers with formal computer science (CS) training, and many schools do not have CS teacher at all. Moreover, teacher retention rate is often low. Beginning teacher attrition rate is particularly high in secondary education. Therefore, in addition to the need for preparing new CS teachers, we also need to support those teachers we have recruited and trained to become better teachers and continue to teach CS. Teacher education literature, especially teacher identity theory, suggests that a strong sense of teacher identity is a major indicator or feature of committed, qualified teachers. However, under the current educational system in the U.S., it could be challenging to establish teacher identity for high school (HS) CS teachers, e.g., due to a lack of teacher certification for CS. This thesis work centers upon understanding the sense of identity HS CS teachers hold and exploring ways of supporting their identity development through a professional development program: the Disciplinary Commons for Computing Educators (DCCE). DCCE has a major focus on promoting reflection on teaching practice and community building. With scaffolded activities such as course portfolio creation, peer review and peer observation among a group of HS CS teachers, it offers opportunities for CS teachers to explicitly reflect on and narrate their teaching, which is a central process of identity building through their participation within the community. In this thesis research, I explore the development of CS teacher identity through professional development programs. I first conducted an interview study with local HS CS teachers to understand their sense of identity and factors influencing their identity formation. I designed and enacted the professional program (DCCE) and conducted case studies with DCCE participants to understand how their

    In 2004, the Mentoring and inquirY using NASA Data on Atmospheric and Earth science for Teachers and Amateurs (MY NASA DATA) project began. The goal of this project is to enable K-12 and citizen science communities to make use of the large volume of Earth System Science data that NASA has collected and archived. One major outcome is to allow students to select a problem of real-life importance, and to explore it using high quality data sources without spending months looking for and then learning how to use a dataset. The key element of the MY NASA DATA project is the implementation of a Live Access Server (LAS). The LAS is an open source software tool, developed by NOAA, that provides access to a variety of data sources through a single, fairly simple, point- and- click interface. This tool truly enables use of the available data - more than 100 parameters are offered so far - in an inquiry-based educational setting. It readily gives students the opportunity to browse images for times and places they define, and also provides direct access to the underlying data values - a key feature of this educational effort. The team quickly discovered, however, that even a simple and fairly intuitive tool is not enough to make most teachers comfortable with data exploration. User feedback has led us to create a friendly LAS Introduction page, which uses the analogy of a restaurant to explain to our audience the basic concept of an LAS. In addition, we have created a "Time Coverage at a Glance" chart to show what data are available when. This keeps our audience from being too confused by the patchwork of data availability caused by the start and end of individual missions. Finally, we have found it necessary to develop a substantial amount of age appropriate documentation, including topical pages and a science glossary, to help our audience understand the parameters they are exploring and how these parameters fit into the larger picture of Earth System Science.

    Cascadia GeoSciences (CG) is a new non-profit membership governed corporation whose main objectives are to conduct and promote interdisciplinary community based earth science research. The primary focus of CG is on geologic hazard assessment and environmental restoration in the Western U.S. The primary geographic region of interest is Humboldt Bay, NW California, within the southern Cascadia subduction zone (SCSZ). This region is the on-land portion of the accretionary prism to the SCSZ, a unique and exciting setting with numerous hazards in an active, dynamic geologic environment. Humboldt Bay is also a region rich in history. Timber harvesting has been occurring in California's coastal forestlands for approximately 150 years. Timber products transported with ships and railroads from Mendocino and Humboldt Counties helped rebuild San Francisco after the 1906 earthquake. Historic land-use of this type now commonly requires the services of geologists, engineers, and biologists to restore road networks as well as provide safe fish passage. While Humboldt Bay is a focus of some of our individual research goals, we welcome regional scientists to utilize CG to support its mission while achieving their goals. An important function of CG is to provide student opportunities in field research. One of the primary charitable contributions of the organization is a student grant competition. Funds for the student grant will come from member fees and contributions, as well as a percent of all grants awarded to CG. A panel will review and select the student research proposal annually. In addition to supporting student research financially, professional members of CG will donate their time as mentors to the student researchers, promoting a student mentor program. The Humboldt Bay region is well suited to support annual student research. Thorough research like this will help unravel some of the mysteries of regional earthquake-induced land-level changes, as well as possible fault

    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.

    We present observations of the Hubble Space Telescope (HST) ``A Preparatory Program to Identify the Single Best Transiting Exoplanet for JWST Early Release Science" for WASP-63b, one of the community targets proposed for the James Webb Space Telescope (JWST) Early Release Science (ERS) program. A large collaboration of transiting exoplanet scientists identified a set of ``community targets" which meet a certain set of criteria for ecliptic latitude, period, host star brightness, well constrained orbital parameters, and strength of spectroscopic features. WASP-63b was one of the targets identified as a potential candidate for the ERS program. It is presented as an inflated planet with a large signal. It will be accessible to JWST approximately six months after the planned start of Cycle 1/ERS in April 2019 making it an ideal candidate should there be any delays in the JWST timetable. Here, we observe WASP-63b to evaluate its suitability as the best target to test the capabilities of JWST. Ideally, a clear atmosphere will be best suited for bench marking the instruments ability to detect spectroscopic features. We can use the strength of the water absorption feature at 1.4 μm as a way to determine the presence of obscuring clouds/hazes. The results of atmospheric retrieval are presented along with a discussion on the suitability of WASP-63b as the best target to be observed during the ERS Program.

    The Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science (MS PHD'S) program focuses on increasing the number of underrepresented minorities (URM) receiving advanced degrees in Earth system sciences (ESS). Subscribing to Aristotle's philosophy that the "whole is greater than the sum of its parts", MS PHD'S uses a synergistic model of tiered mentoring practices, successful minority scientist role models, peer-to-peer community building activities, professional development training techniques, networking opportunities, and state of the art virtual communication tools to facilitate the retention and advancement of underrepresented ESS scientists. Using a three-phase program structure supported by a virtual community, URM students in ESS are afforded opportunities to establish mentoring relationships with successful scientists, build meaningful ties with URM peers and future colleagues, strengthen oral and written communication skills, engage in networking opportunities within premier scientific venues, and maintain continuity of networks formed through program participation. Established in 2003, MS PHD'S is now in its ninth cohort. From the original cohort of 24 participants, the program has grown to support 213 participants. Of these 213 participants, 42 have obtained the doctorate and are employed within the ESS workforce. Another 71 are enrolled in doctoral programs. Looking to the future with the purpose of continually furthering its synergistic philosophy, MS PHD'S has developed a new initiative, Beyond the PhD, designed to support and advance the representation of URM scientists within a global workforce.

  15. Inclusive pedagogy for diverse learners: Science instruction, disability, and the community college

    Moriarty, Mary A.

    The following study examined the use of inclusive pedagogy by science, technology, engineering, and mathematics (STEM) faculty at three community colleges. The study was developed in response to a gap in existing knowledge about inclusive instruction in two-year colleges. The purpose was to identify barriers to the adoption of inclusive teaching methods for diverse learners and students with disabilities, and to propose ways to break down these barriers. Three research questions designed for the study asked about (a) the current teaching styles and methods of curriculum delivery used by community college STEM faculty, (b) the levels of awareness and knowledge of community college STEM faculty about inclusive teaching practices, and (c) the personal, attitudinal, and environmental factors that inhibit community college STEM faculty from using inclusive pedagogical practices to better serve students with disabilities and other diverse students. A sequential method was used to obtain both quantitative and qualitative data regarding instructional practices, pedagogical knowledge, and beliefs about teaching and learning. Two hundred and eleven STEM faculty members responded to a questionnaire that was administered electronically and 11 faculty members were interviewed, 9 of whom were observed in the classroom. Findings revealed that a significant number of these community college faculty members have an inclusive mindset and believe in adapting their instruction in order to accommodate learner differences. These faculty members also appear more knowledgeable about pedagogical practices than what has been reported in previous literature about four-year faculty. Many of the faculty members are using multimodal instructional methods. However, a significant gap still exists between what they believe and know and what is actually put into instructional practice. A number of barriers that prohibit the use and development of inclusive practices were identified in this study

  16. Barriers to Incorporating Climate Change Science into High School and Community College Energy Course Offerings

    2013-05-01

    In reviewing studies evaluating trends in greenhouse gasses, weather, climate and/or ecosystems, it becomes apparent that climate change is a reality. It has also become evident that the energy sector accounts for most of the greenhouse gas emissions with worldwide emissions of carbon dioxide increasing by 31 percent from 1990 to 2005, higher than in the previous thousands of years. While energy courses and topics are presented in high school and community college classes the topic of Climate Change Science is not always a part of the conversation. During the summer of 2011 and 2012, research undergraduates conducted interviews with a total of 39 national community college and 8 high school instructors who participated in a two week Sustainable Energy Education Training (SEET) workshop. Interview questions addressed the barriers and opportunities to the incorporation of climate change as a dimension of an energy/renewable energy curriculum. Barriers found included: there is not enough instruction time to include it; some school administrators including community members do not recognize climate change issues; quality information about climate change geared to students is difficult to find; and, most climate change information is too scientific for most audiences. A Solution to some barriers included dialogue on sustainability as a common ground in recognizing environmental changes/concerns among educators, administrators and community members. Sustainability discussions are already supported in school business courses as well as in technical education. In conclusion, we cannot expect climate change to dissipate without humans making more informed energy and environmental choices. With global population growth producing greater emissions resulting in increased climate change, we must include the topic of climate change to students in high school and community college classrooms, preparing our next generation of leaders and workforce to be equipped to find solutions

  17. Communities of practice in life sciences and the need for brokering.

    2016-01-01

    Etienne Wenger's work on communities of practice is influential in teaching and learning in higher education. A core work of many postgraduate certificate in teaching and learning (PGCert) courses for new lecturers, it is studied, in the main, as a means to understand how to support and encourage students to achieve more effective learning. Communities of practice can also be applied to academics. In the context of the Research Excellence Framework (REF) and its predecessors, the gulf between research-focused and teaching-Focused academics in life sciences has widened, so that in many institutions, these two groups have evolved into two distinct communities of practice; one whose priority is disciplinary research, the other's learning and teaching. However, in 2015, the UK government announced that a Teaching Excellence Framework (TEF) would be introduced into higher education in England, as early as 2017. While the exact details of TEF remain unclear, it is certain that "excellence" and "student satisfaction" will be high on the agenda. It is vital, therefore, that the two communities of practice, research-focused and teaching-focused, find ways to come together in order to ensure high quality teaching and learning. Wenger proposes that this can be done through the process of "brokering", which allows expertise from both communities of practice to cross from one to the other, strengthening both. This should be encouraged at departmental and institutional level, but another vital origin of brokering can be forged at a(n) (inter)national level at meetings such as the SEB Annual Conference, where teaching-focused academics have the opportunity to mix with research-active colleagues. While this paper is informed by recent and current events in the UK Higher Education sector, it is of interest to academics who work in an environment where research and teaching have become separate to any extent.

  18. The motivations and experiences of students enrolled in online science courses at the community college

    Ghosh, Urbi

    An important question in online learning involves how to effectively motivate and retain students in science online courses. There is a dearth of research and knowledge about the experiences of students enrolled in online science courses in community colleges which has impeded the proper development and implementation of online courses and retention of students in the online environment. This study sought to provide an understanding of the relationships among each of the following variables: self-efficacy, task value, negative-achievement emotions, self-regulation learning strategies (metacognition), learning strategy (elaboration), and course satisfaction to student's performance (course final grade). Bandura's social-cognitive theory was used as a framework to describe the relationships among students' motivational beliefs (perceived task value, self-efficacy, and self-regulation) and emotions (frustration and boredom) with the dependent variables (elaboration and overall course satisfaction). A mixed-method design was used with a survey instrumentation and student interviews. A variety of science online courses in biology, genetics, astronomy, nutrition, and chemistry were surveyed in two community colleges. Community colleges students (N = 107) completed a questionnaire during enrollment in a variety of online science online courses. Upon course completion, 12 respondents were randomly selected for follow-up in-depth interviews. Multiple regression results from the study indicate perceived task value and self-regulatory learning strategies (metacognition) were as important predictors for students' use of elaboration, while self-efficacy and the number of prior online courses was not significant predictors for students' elaboration when all four predictors were included. Frustration was a significant negative predictor of overall course satisfaction, and boredom unexpectedly emerged as a positive predictor when frustration was also in the model. In addition, the

    YSS offers the opportunity to raise awareness, build excitement, and make connections with educators, students and the public about planetary science activities. The planetary science education and public outreach (E/PO) community is engaging and educating their audiences through ongoing mission and program activities. Based on discussion with partners, the community is presenting its products in the context of monthly thematic topics that are tied to the big questions of planetary science: how did the Sun’s family of planets and bodies originate and how have they evolved; and how did life begin and evolve on Earth, has it evolved elsewhere in our solar system, and what are characteristics that lead to the origins of life? Each month explores different compelling aspects of the solar system - its formation, volcanism, ice, life. Resources, activities, and events are interwoven in thematic context, and presented with ideas through which formal and informal educators can engage their audiences. The month-to-month themes place the big questions in a logical sequence of deepening learning experiences - and highlight mission milestones and viewing events. YSS encourages active participation and communication with its audiences. It includes nation-wide activities, such as a Walk Through the Solar System, held between October 2010 to March 2011, in which museums, libraries, science centers, schools, planetariums, amateur astronomers, and others are kicking off YSS by creating their own scale models of the solar system and sharing their events through online posting of pictures, video, and stories. YSS offers the E/PO community the opportunity to collaborate with each other and partners. The thematic approach leverages existing products, providing a home and allowing a “shelf life” that can outlast individual projects and missions. The broad themes highlight missions and programs multiple times. YSS also leverages existing online resources and social media. Hosted on

    2008-10-01

    Introduction The South African health system has disturbing inequalities, namely few black doctors, a wide divide between urban and rural sectors, and also between private and public services. Most medical training programs in the country consider only applicants with higher-grade preparation in mathematics and physical science, while most secondary schools in black communities have limited capacity to teach these subjects and offer them at standard grade level. The Faculty of Health Sciences at Walter Sisulu University (WSU) was established in 1985 to help address these inequities and to produce physicians capable of providing quality health care in rural South African communities. Intervention Access to the physician training program was broadened by admitting students who obtained at least Grade C (60%) in mathematics and physical science at standard grade, and who demonstrated appropriate personal attributes. An innovative curriculum, combining problem-based learning with community-based education (PBL/CBE) in small tutorial group settings, was also adopted. This approach was aimed at educating and graduating a broader cohort of students, while training future doctors to identify, analyze, and treat health problems in the rural South African context. Outcomes To date, 745 doctors (72% black Africans) have graduated from the program, and 511 students (83% black Africans) are currently enrolled. After the PBL/CBE curriculum was adopted, the attrition rate for black students dropped from 23% to 80%, and the proportion of students graduating within the minimum period rose from 55% to >70%. Many graduates are still completing internships or post-graduate training, but preliminary research shows that 36% percent of graduates practice in small towns and rural settings. Further research is underway to evaluate the impact of their training on health services in rural Eastern Cape Province and elsewhere in South Africa. Conclusions The WSU program increased access to

    The San Diego Regional Climate Education Partnership has formed an innovative and collaborative team whose mission is to implement a research-based climate science education and communications program to increase knowledge about climate science among highly-influential leaders and their communities and foster informed decision making based on climate science and impacts. The team includes climate scientists, behavioral psychologists, formal and informal educators and communication specialists. The Partnership's strategic plan has three major goals: (1) raise public understanding of the causes and consequences of climate change; (2) identify the most effective educational methods to educate non-traditional audiences (Key Influentials) about the causes and consequences of climate change; and (3) develop and implement a replicable model for regional climate change education. To implement this strategic plan, we have anchored our project on three major pillars: (1) Local climate science (causes, impacts and long-term consequences); (2) theoretical, research-based evaluation framework (TIMSI); and (3) Key! Influentials (KI) as primary audience for messages (working w! ith and through them). During CCEP-I, the Partnership formed and convened an advisory board of Key Influentials, completed interviews with a sample of Key Influentials, conducted a public opinion survey, developed a website (www.sandiego.edu/climate) , compiled inventories on literature of climate science education resources and climate change community groups and local activities, hosted stakeholder forums, and completed the first phase of on an experiment to test the effects of different messengers delivering the same local climate change message via video. Results of 38 KI Interviews provided evidence of local climate knowledge, strong concern about climate change, and deeply held values related to climate change education and regional leadership. The most intriguing result was that while 90% of Key

    Over the past decade, NASA's Science Mission Directorate (SMD) has funded four education and public outreach (E/PO) forums, aligned with each of its science divisions, including Astrophysics, Earth Science, Heliophysics, and Planetary Science. Together, these forums help organize individual division E/PO programs into a coordinated, effective, efficient, nationwide effort that shares the scientific discoveries of NASA across a broad array of audiences. In the past four-and-a-half years, the Planetary Science Division's Forum - in collaboration with the other three Forums - has worked to support its community of education professionals and scientists involved in E/PO to communicate, collaborate, and strengthen their efforts. The Forum's work encompasses identification of best practices based on educational research, increasing understanding of needs through audience-based working groups, the development of strategic collaborations and partnerships to increase programmatic reach, and the creation of strategic resources to support community members in their E/PO work (e.g., an online workspace for the community to communicate, collaborate, and share practices; recommendations to scientists for increasing impact in educational settings; a one-stop shop for NASA SMD classroom and informal education products, http://nasawavelength.org). Drawing on evaluation data, the presentation will explore what resources and support mechanisms are valued by the community, ways the community uses the available resources, and the outcomes of the effort to date.

    This report summarizes the work of the University of Utah, which was a member of the National Fusion Collaboratory (NFC) Project funded by the United States Department of Energy (DOE) under the Scientific Discovery through Advanced Computing Program (SciDAC) to develop a persistent infrastructure to enable scientific collaboration for magnetic fusion research. A five year project that was initiated in 2001, it the NFC built on the past collaborative work performed within the U.S. fusion community and added the component of computer science research done with the USDOE Office of Science, Office of Advanced Scientific Computer Research. The project was itself a collaboration, itself uniting fusion scientists from General Atomics, MIT, and PPPL and computer scientists from ANL, LBNL, and Princeton University, and the University of Utah to form a coordinated team. The group leveraged existing computer science technology where possible and extended or created new capabilities where required. The complete finial report is attached as an addendum. The In the collaboration, the primary technical responsibility of the University of Utah in the collaboration was to develop and deploy an advanced scientific visualization service. To achieve this goal, the SCIRun Problem Solving Environment (PSE) is used on FusionGrid for an advanced scientific visualization service. SCIRun is open source software that gives the user the ability to create complex 3D visualizations and 2D graphics. This capability allows for the exploration of complex simulation results and the comparison of simulation and experimental data. SCIRun on FusionGrid gives the scientist a no-license-cost visualization capability that rivals present day commercial visualization packages. To accelerate the usage of SCIRun within the fusion community, a stand-alone application built on top of SCIRun was developed and deployed. This application, FusionViewer, allows users who are unfamiliar with SCIRun to quickly create

    The objectives of the Lisbon declaration (2000) and the affirmation of the European Commission that there is a need to promote more widely inquiry based science education methodologies in primary and secondary schools and to support teachers' networks (2007), were the basis for launch by European Schoolnet (EUN) of Scientix, a new web-based information platform for science education in Europe. It's aim is to ensure the regular dissemination and sharing of progress, know-how, and best practices in the field of science education and providing a feedback mechanism. Scientix is a three-year project run by EUN since December 2009 on behalf of the European Commission Directorate General Research and is funded under the 7th Framework Programme. The portal (http://www.scientix.eu), available in six European languages, offers a resource repository containing hundreds of teaching materials from European projects, but also research reports and policy-making documents; a translation on demand service for the teaching materials towards any of the 23 languages of the European Union; a community including a forum and chat rooms; an online news service featuring international science education topics and a calendar of forthcoming events and training opportunities; and also a newsletter sent once a month to registered users. The Scientix main targets are teachers, providing teaching materials, scientific support and documentation that are able to give them some quality tools for the development and implementation of inquiry based science education teaching methodologies. Besides the website, several events and workshops will be organized during the three years of the project. Workshops and newsletters to inform science teachers, give them tools to use the Scientix platform in class effectively and meet other science teachers in Europe will be organized from 2010 to 2012 and will take place in several European countries. An example of this was the Scientix European Conference that

    Light, Jennifer

    Learning communities and their strategies for enrolling cohort groups of students in a common set of classes organized around a theme or linked with residence life have come to light over the past twenty years. However, living-learning communities (LLC) and their role in retention, engagement, and intellectual development for engineering and science students have yet to be fully explored. What aspects of a LLC are most beneficial to science and engineering students? What are the learning needs of engineering and science students that are best met with LLCs? These questions were the basis for assessment of a new LLC program developed at Washington State University specifically to increase retention, academic achievement, and engagement of engineering and science students. A first-year semester-long pilot LLC program was developed at Washington State University specifically for entering engineering majors. The program was expanded the following year to include biotech science majors. The first LLC had 55 self-selected engineering participants. Students were housed in the same residence hall, registered for three common classes, and participated in a non-credit bearing weekly peer-facilitated study group. The second year 81 students self-selected into the program; 59 engineering and 22 biotech majors. Students were housed in a common residence hall and registered for three common classes. Students participated in a two-credit freshman seminar class instead of the once-weekly study group used the previous year. Results indicate students were engaged with peers and in college activities, had mixed academic improvement, and engineering students were retained at higher rates in their major when compared to non-participating peers and biotech participants. Second year LLC students had higher grade averages than comparison peers despite lower incoming preparedness. Higher engagement levels were confirmed by triangulation with national survey comparisons, observations, focus

    Transformation of research in all biological fields necessitates the design, analysis and, interpretation of large data sets. Preparing students with the requisite skills in experimental design, statistical analysis, and interpretation, and mathematical reasoning will require both curricular reform and faculty who are willing and able to integrate mathematical and statistical concepts into their life science courses. A new Faculty Learning Community (FLC) was constituted each year for four years to assist in the transformation of the life sciences curriculum and faculty at a large, Midwestern research university. Participants were interviewed after participation and surveyed before and after participation to assess the impact of the FLC on their attitudes toward teaching, perceived pedagogical skills, and planned teaching practice. Overall, the FLC had a meaningful positive impact on participants' attitudes toward teaching, knowledge about teaching, and perceived pedagogical skills. Interestingly, confidence for viewing the classroom as a site for research about teaching declined. Implications for the creation and development of FLCs for science faculty are discussed. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(6):517-525, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

    Social media like blogs, micro-blogs or social networks are increasingly being investigated and employed to detect and predict trends for not only social and physical phenomena, but also to capture environmental information. Here we argue that opportunistic biodiversity observations published through Twitter represent one promising and until now unexplored example of such data mining. As we elaborate, it can contribute to real-time information to traditional ecological monitoring programmes including those sourced via citizen science activities. Using Twitter data collected for a generic assessment of social media data in ecological monitoring we investigated a sample of what we denote biodiversity observations with species determination requests (N = 191). These entail images posted as messages on the micro-blog service Twitter. As we show, these frequently trigger conversations leading to taxonomic determinations of those observations. All analysed Tweets were posted with species determination requests, which generated replies for 64% of Tweets, 86% of those contained at least one suggested determination, of which 76% were assessed as correct. All posted observations included or linked to images with the overall image quality categorised as satisfactory or better for 81% of the sample and leading to taxonomic determinations at the species level in 71% of provided determinations. We claim that the original message authors and conversation participants can be viewed as implicit or embryonic citizen science communities which have to offer valuable contributions both as an opportunistic data source in ecological monitoring as well as potential active contributors to citizen science programmes.

    2017-01-01

    Following a more than a century of scientific aircraft and ballooning there is a sense that a renaissance of sorts is at hand in the aviation industry. The advent of incredibly miniaturized autopilots, inertial navigation systems, GPS antennae, and payloads has sparked a revolution in manned and unmanned aircraft. Improved SATCOM and onboard computing has enabled realtime data processing and improved transfer of data on and off the aircraft, making flight planning and data collection more efficient and effective. Electric propulsion systems are scaling up to larger and larger vehicles as evidenced by the NASA GL-10, which is leading to a new X-plane and is leading to renewed interest in personal air vehicles. There is also significant private and government investments in the development of High Altitude, Long Endurance (HALE) aircraft. This presentation will explore how such developments are likely to improve our ability to observe earth systems processes from aircraft by providing an overview of current NASA Airborne Science capabilities, followed by a brief discussion of new technologies being applied to Airborne Science missions, and then conclude with an overview of new capabilities on the horizon that are likely to be of interest to the Earth Science community.

    Harvey, Robert Christopher

    The purpose of this study was to determine the effects of two conceptually based instructional strategies on science achievement and attitudes of community college biological science students. The sample consisted of 277 students enrolled in General Biology 1, Microbiology, and Human Anatomy and Physiology 1. Control students were comprised of intact classes from the 2005 Spring semester; treatment students from the 2005 Fall semester were randomly assigned to one of two groups within each course: written narrative (WN) and illustration (IL). WN students prepared in-class written narratives related to cell theory and metabolism, which were taught in all three courses. IL students prepared in-class illustrations of the same concepts. Control students received traditional lecture/lab during the entire class period and neither wrote in-class descriptions nor prepared in-class illustrations of the targeted concepts. All groups were equivalent on age, gender, ethnicity, GPA, and number of college credits earned and were blinded to the study. All interventions occurred in class and no group received more attention or time to complete assignments. A multivariate analysis of covariance (MANCOVA) via multiple regression was the primary statistical strategy used to test the study's hypotheses. The model was valid and statistically significant. Independent follow-up univariate analyses relative to each dependent measure found that no research factor had a significant effect on attitude, but that course-teacher, group membership, and student academic characteristics had a significant effect (p students scored significantly lower in achievement than A&P students; (2) Microbiology students scored significantly higher in achievement than Biology students; (3) Written Narrative students scored significantly higher in achievement than Control students; and (4) GPA had a significant effect on achievement. In addition, given p students averaged lower in achievement than A&P students

    This article describes the importance that high school computer science teachers place on a teachers' professional learning community designed around an inquiry- and equity-oriented approach for broadening participation in computing. Using grounded theory to analyze four years of teacher surveys and interviews from the Exploring Computer Science (ECS) program in the Los Angeles Unified School District, this article describes how participating in professional development activities purposefully aimed at fostering a teachers' professional learning community helps ECS teachers make the transition to an inquiry-based classroom culture and break professional isolation. This professional learning community also provides experiences that challenge prevalent deficit notions and stereotypes about which students can or cannot excel in computer science.

    2016-01-01

    The Gemini Science User Support Department (SUSD) was formed a little more than a year ago to create a collaborative community of users and staff and to consolidate existing post-observing support throughout the observatory for more efficient use of resources as well as better visibility amongst our user community. This poster is an opportunity to exchange ideas about how Gemini can improve your experience while working with the Observatory and present details about new avenues of post-observing support coming soon. We encourage your feedback at any time.Shortly after its creation, the SUSD conducted a complete revision of the communication cycle between Gemini and its community of researchers. The cycle was then revisited from the perspective of an astronomer interested in using Gemini for their research. This exercise led to a series of proposed changes that are currently under development, and the implementation of a sub-selection is expected in 2016, including the following. (1) Email notifications: Gemini users will receive new forms of email communications that are more instructive and tailored to their program. The objective is to direct the users more efficiently toward the useful links and documentation all along the lifecycle of the program, from phaseII to after the data are completely reduced. (2) HelpDesk system: The HelpDesk will become more user-friendly and transparent. (3) Webpages: The organization of the Gemini webpages will be redesigned to optimize navigation; especially for anything regarding more critical periods likes phaseIs and phaseIIs. (4) Data Reduction User Forum: Following recommendations from Gemini users, new capabilities were added to the forum, like email notifications, and a voting system, in order to make it more practical. This forum's objective is to bring the Gemini community together to exchange their ideas, thoughts, questions and solutions about data reduction, a sort of Reddit, StackOverflow or Slashdot for Gemini data.

  15. Reality of using a model from local governments' perspective-How science community can help?

    2016-12-01

    Local governments across the US use historic data to approve capital improvement projects and update comprehensive/zoning plans. Due to the effects of climate change, historic data sets are no longer suitable, which requires communities to use climate models to project the future. However, the use of climate models also presents challenges for local governments such as: Variations between models: Because model-development methodologies vary, different climate models provide different end results. A local governments' decision concerning which climate model to use is tricky because the model drives policy direction and infrastructure investments that can be both expensive and controversial. Communicating the gaps of a model: There are always uncertainties associated with modeling. These gaps may range from the scale of a model to the type of data used in modeling. Effectively communicating this to a community is crucial to gain political support. Managing politics associated with using a model: In many cases, models project changes to the built environment that will detrimentally affect private property owners. This can result in strong push back from the community and could threaten the local tax base. Scientists have important roles; from development to delivery of models to assisting local governments navigate through these challenges. Bringing in entities with experience of working with local governments can contribute to a successful outcome. In this proposed session, ICLEI-Local Governments for Sustainability will use the USGS CoSMoS as a case study for lessons learned in establishing a framework for effective collaboration between local governments and the science community.

    Dixon, Brent; Hanson, Duane; Matthern, Gretchen

    2003-02-27

    A number of broad perspective technology roadmaps have been developed in the last few years as tools for coordinating nation-wide research in targeted areas. These roadmaps share a common characteristic of coalescing the associated stakeholder groups into a special-interest community that is willing to work cooperatively in achieving the roadmap goals. These communities are key to roadmap implementation as they provide the collaborative energy necessary to obtain the political support and funding required for identified science and technology development efforts. This paper discusses the relationship between roadmaps and special-interest communities, using the recently drafted Department of Energy's Long-Term Stewardship Science and Technology Roadmap as a case study. Specific aspects this roadmap's design facilitated the development of a long-term stewardship community while specific realities during roadmap development impacted the realization of the design.

    Background Illegal plasma collecting activities in mid 1990s caused a large number of human immunodeficiency virus (HIV) infections in rural areas of central-eastern China. Although most of these activities have been stopped, there were few reports on secondary transmission from infected former plasma donors to their spouses and from infected mothers to their children. This study was to determine the extent of HIV infections among young children in a rural community with a large proportion of plasma donors.Methods A survey was conducted among children aged under 7 years in a former plasma donating community in September 2000: finger blood was collected for HIV antibody testing. Another survey was repeated among children aged under 8 years and their families in the same community in April 2001: urine samples were collected for HIV testing. HIV positive children and samples of HIV negative children, whose mothers were positive based on 2001 survey, were followed up until September 2002 to investigate HIV seroconversion, disease progression and HIV strain analysis. Questionnaires were administered to collect information on children's delivery, breast feeding, medical history and their parents' commercial blood donation history and HIV status.Results Among 169 children surveyed in 2000, 10 (5.9%) were HIV positive. Of 224 children, 11 were positive in 2001. The overall prevalence rate in the two surveys was 5.0% (17/337) when counting 56 repeated children only once. Of children born to HIV positive mothers, 28.9% were infected. A seroconversion rate of 2.5 per 100 child-years was observed by following up 28 HIV negative children. No statistically significant associations were found between children's HIV infection and their histories of blood transfusion, surgery, immunization injection or medical injections. All infections were HIV-1 subtype B' strain, the average dispersion rate is 7.4%. DNA sequence analysis showed a close relationship between the seroconverted

    2012-12-01

    The impact of global climate change is far-reaching, both for humanity and for the environment. It is essential that our students be provided a strong scientific background for the role of natural and human caused climate change so that they are better prepared to become involved in the discussion. Here the author reveals a successful model designed for use with a diverse student body at the community college level. Teaching strategies beyond the traditional lecture and exam style include: web-based resources such as static websites along with dynamic blogging tools, post-lecture cooperative learning review sessions, weekly current event research projects, use of rubrics to assist students in their own project evaluation before submission, and a research paper utilizing the Skeptical Science website to examine the validity of the most common climate change myths.

    Astronomical data are gathered through a very large number of heterogeneous techniques and stored in very diversified and often incompatible data repositories. Moreover in the e-science environment, it is needed to integrate services across distributed, heterogeneous, dynamic "virtual organizations" formed by different resources within a single enterprise and/or external resource sharing and service provider relationships. The DAME/VONeural project, run jointly by the University Federico II, INAF (National Institute of Astrophysics) Astronomical Observatories of Napoli and the California Institute of Technology, aims at creating a single, sustainable, distributed e-infrastructure for data mining and exploration in massive data sets, to be offered to the astronomical (but not only) community as a web application. The framework makes use of distributed computing environments (e.g. S.Co.P.E.) and matches the international IVOA standards and requirements. The integration process is technically challenging due to ...

  4. The Myth of Global Science Collaboration - Collaboration patterns in epistemic communities

    CERN Document Server

    Hennemann, Stefan; Liefner, Ingo

    2011-01-01

    Scientific collaboration is often perceived as a joint global process that involves researchers worldwide, regardless of their place of work and residence. Globalization of science, in this respect, implies that collaboration among scientists takes place along the lines of common topics and irrespective of the spatial distances between the collaborators. The networks of collaborators, termed 'epistemic communities', should thus have a space-independent structure. This paper shows that such a notion of globalized scientific collaboration is not supported by empirical data. It introduces a novel approach of analyzing distance-dependent probabilities of collaboration. The results of the analysis of six distinct scientific fields reveal that intra-country collaboration is about 10-50 times more likely to occur than international collaboration. Moreover, strong dependencies exist between collaboration activity (measured in co-authorships) and spatial distance when confined to national borders. However, the fact th...

    2013-11-01

    Emerging from Bandura's Social Learning Theory, this study of in-service elementary school teachers examined the effects of sustained Professional Learning Communities (PLCs) on self-efficacy in science teaching. Based on mixed research methods, and a non-equivalent control group experimental design, the investigation explored changes in personal self-efficacy and outcome expectancy among teachers engaged in PLCs that featured Demonstration Laboratories, Lesson Study, and annual Summer Institutes. Significant changes favoring the experimental group were found on all quantitative measures of self-efficacy. Structured clinical interviews revealed that observed changes were largely attributable to a wide range of direct (mastery) and vicarious experiences, as well as emotional reinforcement and social persuasion.

  6. Creating a Global Community of Learners in Nursing and Beyond: Caring Science, Mindful Practice MOOC.

    Sitzman, Kathleen L; Jensen, Andrea; Chan, Sang

    The aim was to examine the usefulness of a massive open online course (MOOC) on caring and mindfulness to a broad international audience that included nurses, allied health professionals, and others. MOOCs in higher education have been evident since 2008. Very few MOOCs on nursing topics have appeared since that time. Exploration was needed regarding how MOOCs could be employed to share nursing knowledge with national and international communities. Two "Caring Science, Mindful Practice" MOOC sessions were examined. Demographics, learner satisfaction, course flow, and perceived usefulness of content were analyzed. Learners from varied backgrounds participated. Higher than expected course activity levels and completion rates suggested effective learner engagement. Excellent course ratings demonstrated that content and delivery methods were effective. Active learners communicated specific plans to apply new knowledge in the future. MOOCs facilitate learning where participants learn about topics of interest in nursing and beyond.

Among a few initiatives involving university accountability for advancing public interests, a small CTSA workgroup devised a community engagement (CE) logic model that organizes common activities within a university-community infrastructure to facilitate CE in research. Whereas the model focuses on the range of institutional CE inputs, it purposefully does not include an approach for assessing how CE influences research implementation and outcomes. Rather, with communities and individuals beginning to transition into new research roles, this article emphasizes studying CE through specific relationship types and assessing how expanded research teams contribute to the full spectrum of translational science.The authors propose a typology consisting of three relationship types-engagement, collaboration, and shared leadership-to provide a foundation for investigating community-academic contributions to the new CTSA research paradigm. The typology shifts attention from specific community-academic activities and, instead, encourages analyses focused on measuring the strength of relationships through variables like synergy and trust. The collaborative study of CE relationships will inform an understanding of CTSA infrastructure development in support of translational research and its goal, which is expressed in the logic model: better science, better answers, better population health.

    Focusing on the interplay of context and language, this study examined a group of high school students and their mentors' use of language during a robotics competition. This informal setting allowed us to gain insights into the mediation and manifestation of power within the group. Using critical discourse analysis of competition transcripts and interviews we found that both students and mentors felt a sense of ownership and community leading to symmetry in power amongst them. The shift in power led to greater student ownership and agency and created a space for authentic and meaningful science learning. The context of the robotics competition mediated discourse practices that were different from students' classroom experiences in that they were descriptive, relational, explanatory, and had an authentic evaluative dimension. This engaged the participants to co-construct and critique each other's knowledge claims thereby engaging in scientific practices that approximated the practices of scientists. Our study presents an argument that language and context reflexively influenced one another and reduced the imbalance of power amongst the participants thereby adding a new dimension to what has already been established about the conditions under which authentic science learning is likely to occur.

    We describe a three hour inquiry activity involving converging lenses and telescopes as part of a semester-long astronomy lab course for non-science majors at Hartnell Community College in Salinas, CA. Students were shown several short demonstrations and given the chance to experiment with the materials, after which there was a class discussion about the phenomena they observed. Students worked in groups of 2-4 to design their own experiments to address a particular question of interest to them and then presented their findings to the class. An instructor-led presentation highlighted the students' discoveries and the lab's content goals, followed by a short worksheet-based activity that guided them in applying their new knowledge to build a simple telescope using two converging lenses. The activity was successful in emphasizing communication skills and giving students opportunities to engage in the process of science in different ways. One of the biggest challenges in designing this activity was covering all ...

    for the purpose of assessing the quality of citizen science observations. It has been found that citizen science observations are essential for capturing localised convective storms. Citizen scientists want their observations to be used to gain meaningful information and tackle local issues. Data has therefore been utilised to build, calibrate and validate hydrological models and support a range of catchment management applications. This has further demonstrated the value of citizen science, along with the social benefits it has to offer. Other communities are also beginning to source funding and implement their own monitoring schemes, indicating that they are both capable and self-motivated. Citizen science makes use of evolving and more readily available technology, providing catchment stakeholders with vital information. Although these types of observations present various challenges, it is argued that a citizen science approach is not intending to replace traditional techniques, rather they can be used to complement them, fill the gaps and/or provide an indication of catchment behaviour across space and through time.

    Soil complexity, heterogeneity and transferability make it valuable in forensic investigations to help obtain clues as to the origin of an unknown sample, or to compare samples from a suspect or object with samples collected at a crime scene. In a few countries, soil analysis is used in matters from site verification to estimates of time after death. However, up to date the application or use of soil information in criminal investigations has been limited. In particular, comparing bacterial communities in soil samples could be a useful tool for forensic science. To evaluate the relevance of this approach, a blind test was performed to determine the origin of two questioned samples (one from the mock crime scene and the other from a 50:50 mixture of the crime scene and the alibi site) compared to three control samples (soil samples from the crime scene, from a context site 25m away from the crime scene and from the alibi site which was the suspect's home). Two biological methods were used, Ribosomal Intergenic Spacer Analysis (RISA), and 16S rRNA gene sequencing with Illumina Miseq, to evaluate the discriminating power of soil bacterial communities. Both techniques discriminated well between soils from a single source, but a combination of both techniques was necessary to show that the origin was a mixture of soils. This study illustrates the potential of applying microbial ecology methodologies in soil as an evaluative forensic tool. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  12. The JASMIN Cloud: specialised and hybrid to meet the needs of the Environmental Sciences Community

    Cloud computing provides enormous opportunities for the research community. The large public cloud providers provide near-limitless scaling capability. However, adapting Cloud to scientific workloads is not without its problems. The commodity nature of the public cloud infrastructure can be at odds with the specialist requirements of the research community. Issues such as trust, ownership of data, WAN bandwidth and costing models make additional barriers to more widespread adoption. Alongside the application of public cloud for scientific applications, a number of private cloud initiatives are underway in the research community of which the JASMIN Cloud is one example. Here, cloud service models are being effectively super-imposed over more established services such as data centres, compute cluster facilities and Grids. These have the potential to deliver the specialist infrastructure needed for the science community coupled with the benefits of a Cloud service model. The JASMIN facility based at the Rutherford Appleton Laboratory was established in 2012 to support the data analysis requirements of the climate and Earth Observation community. In its first year of operation, the 5PB of available storage capacity was filled and the hosted compute capability used extensively. JASMIN has modelled the concept of a centralised large-volume data analysis facility. Key characteristics have enabled success: peta-scale fast disk connected via low latency networks to compute resources and the use of virtualisation for effective management of the resources for a range of users. A second phase is now underway funded through NERC's (Natural Environment Research Council) Big Data initiative. This will see significant expansion to the resources available with a doubling of disk-based storage to 12PB and an increase of compute capacity by a factor of ten to over 3000 processing cores. This expansion is accompanied by a broadening in the scope for JASMIN, as a service available to

    Fulfilling the broader impact of a research project in Earth and environmental sciences is an excellent opportunity for educational and outreach activities that connect scientists and society and enhance students and community engagement in STEM fields in general and in Earth, space, and environmental sciences in particular. Here we present the experience developed in this endeavor as part of our Partnerships for Enhanced Engagement in Research (PEER) project sponsored by USAID/NSF/NAS. The project introduced educational and outreach activities that included core curriculum course development for university students from all majors, community-based learning projects, citizen science and outreach programs to school students and community members. Through these activities, students worked with the project scientists on a variety of activities that ranged from citizen science and undergraduate research to run mass experiments that measure the quality of air, drinking water, and ultraviolet level in greater Cairo, Egypt, to community awareness campaigns through the production of short documentaries and communicating them with stakeholders and target groups, including schools and TV stations. The activities enhanced students learning and the public awareness on climate change and the underlying role of human activities. It also connected effectively the project scientists with college and university students a well as the wider segments of the society, which resulted in a host of benefits including better scientific literacy and appreciation to the role of scientists, promoting scientists as role models, sharing the values of science, and motivating future generations to puruse a career in science This work is part of the PEER research project 2-239 sponsored by USAID/NSF/NAS Project Link (at National Academies website): http://sites.nationalacademies.org/PGA/dsc/peerscience/PGA_084046.htm website: http://CleanAirEgypt.org Links to cited work: Core Curriculum Course

  14. Critical analysis of science-related texts in a breastfeeding information, support, and advocacy community of practice

    Science.gov (United States)

    Lottero-Perdue, Pamela S.

    This study examines the way in which women in a breastfeeding information, support, and advocacy (BISA) community of practice critically engage with written/oral science-related texts. The range of texts that these participants encounter is explored and two critical reading approaches are investigated: (1) critical science reading, or reading to assess text validity; and (2) critical science-related text analysis (CSTA), or reading to determine the way in which a text positions subjects or reality, is indicative of particular interests, or leaves out particular voices. The former has been addressed by science education research; the latter is based upon feminist poststructuralism and critical literacy literature. Participants in BISA encounter a wide range of science-related texts, and, to varying degrees, assess the validity of these texts based upon what they know about science, their own and others' experiences, and practical knowledge. Participants also engage in CSTA to greater and lesser extents. Also, experts in BISA are entrusted by participants in the organization to identify valid and trustworthy texts. Differences in critical science reading across participants and texts are discussed, as are the purposes for critical science reading and conditions in BISA that support these critical practices. This study informs both science education and critical literacy research, argues that critical science reading and CSTA are worthwhile practices of both everyday folks and students, and suggests that educators encourage engagement in these practices by presenting students with conflicting science-related texts, encouraging doubt in and epistemic distancing from science-related texts, and modeling critical engagement with science-related texts for students.

  15. Leveraging Open Standards and Technologies to Enhance Community Access to Earth Science Lidar Data

    Lidar (Light Detection and Ranging) data, collected from space, airborne and terrestrial platforms, have emerged as an invaluable tool for a variety of Earth science applications ranging from ice sheet monitoring to modeling of earth surface processes. However, lidar present a unique suite of challenges from the perspective of building cyberinfrastructure systems that enable the scientific community to access these valuable research datasets. Lidar data are typically characterized by millions to billions of individual measurements of x,y,z position plus attributes; these "raw" data are also often accompanied by derived raster products and are frequently terabytes in size. As a relatively new and rapidly evolving data collection technology, relevant open data standards and software projects are immature compared to those for other remote sensing platforms. The NSF-funded OpenTopography Facility project has developed an online lidar data access and processing system that co-locates data with on-demand processing tools to enable users to access both raw point cloud data as well as custom derived products and visualizations. OpenTopography is built on a Service Oriented Architecture (SOA) in which applications and data resources are deployed as standards compliant (XML and SOAP) Web services with the open source Opal Toolkit. To develop the underlying applications for data access, filtering and conversion, and various processing tasks, OpenTopography has heavily leveraged existing open source software efforts for both lidar and raster data. Operating on the de facto LAS binary point cloud format (maintained by ASPRS), open source libLAS and LASlib libraries provide OpenTopography data ingestion, query and translation capabilities. Similarly, raster data manipulation is performed through a suite of services built on the Geospatial Data Abstraction Library (GDAL). OpenTopography has also developed our own algorithm for high-performance gridding of lidar point cloud data

    The James Webb Space Telescope (JWST) will likely revolutionize transiting exoplanet atmospheric science, due to a combination of its capability for continuous, long duration observations and its larger collecting area, spectral coverage, and spectral resolution compared to existing space-based facilities. However, it is unclear precisely how well JWST will perform and which of its myriad instruments and observing modes will be best suited for transiting exoplanet studies. In this article, we describe a prefatory JWST Early Release Science (ERS) Cycle 1 program that focuses on testing specific observing modes to quickly give the community the data and experience it needs to plan more efficient and successful transiting exoplanet characterization programs in later cycles. We propose a multi-pronged approach wherein one aspect of the program focuses on observing transits of a single target with all of the recommended observing modes to identify and understand potential systematics, compare transmission spectra at overlapping and neighboring wavelength regions, confirm throughputs, and determine overall performances. In our search for transiting exoplanets that are well suited to achieving these goals, we identify 12 objects (dubbed community targets'') that meet our defined criteria. Currently, the most favorable target is WASP-62b because of its large predicted signal size, relatively bright host star, and location in JWST's continuous viewing zone. Since most of the community targets do not have well-characterized atmospheres, we recommend initiating preparatory observing programs to determine the presence of obscuring clouds/hazes within their atmospheres. Measurable spectroscopic features are needed to establish the optimal resolution and wavelength regions for exoplanet characterization. Other initiatives from our proposed ERS program include testing the instrument brightness limits and performing phase-curve observations. The latter are a unique challenge

    Low temperature plasma (LTP) treatment of biological tissue is a promising path toward sterilization of bacteria due to its versatility and ability to operate under well-controlled and relatively mild conditions. The present collaborative research of an interdisciplinary team of investigators at University of Maryland, College Park (UMD), and University of California, Berkeley (UCB) focused on establishing our knowledge based with regard to low temperature plasma-induced chemical modifications in biomolecules that result in inactivation due to various plasma species, including ions, reactive radicals, and UV/VUV photons. The overall goals of the project were to identify and quantify the mechanisms by which low and atmospheric pressure plasma deactivates endotoxic biomolecules. Additionally, we wanted to understand the mechanism by which atmospheric pressure plasmas (APP) modify surfaces and how these modifications depend on the interaction of APP with the environment. Various low pressure plasma sources, a vacuum beam system and several atmospheric pressure plasma sources were used to accomplish this. In our work we elucidated for the first time the role of ions, VUV photons and radicals in biological deactivation of representative biomolecules, both in a UHV beam system and an inductively coupled, low pressure plasma system, and established the associated atomistic biomolecule changes. While we showed that both ions and VUV photons can be very efficient in deactivation of biomolecules, significant etching and/or deep modification (~200 nm) accompanied these biological effects. One of the most important findings in this work is the significant radical-induced deactivation and surface modification can occur with minimal etching. However, if radical fluxes and corresponding etch rates are relatively high, for example at atmospheric pressure, endotoxic biomolecule film inactivation may require near-complete removal of the film. These findings motivated further work at

  19. Creating a virtual community of practice to investigate legitimate peripheral participation by African American middle school girls in science activities

    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.

  10. Domestic Forests: A New Paradigm for Integrating Local Communities' Forestry into Tropical Forest Science

    Directory of Open Access Journals (Sweden)

    Francois Verdeaux

    2007-12-01

    Full Text Available Despite a long history of confrontation between forest agencies and forest people, "indigenous" or "local" practices are increasingly considered as a viable alternative of forest management. This paper is a synthesis derived from various long-term research programs carried out by the authors in Southeast Asia and Africa on forests managed by farmers. These researches looked at local practices and underlying science, including their social, political, and symbolic dimensions. They also addressed evolutionary trends and driving forces, as well as potential and limits for forest conservation and development, mitigation of deforestation, biodiversity conservation, and poverty alleviation in a context of global environmental, political, and social change. We discuss how forest management by local communities, contrary to the unified models of professional forest management, exhibits a high historical and geographical diversity. The analysis we draw from the various examples we studied reveals several invariants, which allows proposing the unifying paradigm of "domestic forest." The first universal feature concerns the local managers themselves, who are, in their vast majority, farmers. Management practices range from local interventions in the forest ecosystem, to more intensive types of forest culture, and ultimately to permanent forest plantation. But in all cases, forest management is closely integrated with agriculture. The second universal feature concerns the conceptual continuity of planted forests with the natural forest, in matters of vegetation's structure and composition as well as economic traits and ecosystem services. The resulting forest is uneven-aged, composed of several strata, harboring a large diversity of species, and producing a wide range of products, with timber seldom being the dominant one. The term "domestic forest" aims at highlighting the close relationship the domestication process establishes between a specific human

  11. Self-regulated Learning in a Hybrid Science Course at a Community College

    Science.gov (United States)

    Manuelito, Shannon Joy

    Community college students are attracted to courses with alternative delivery formats such as hybrid courses because the more flexible delivery associated with such courses provides convenience for busy students. In a hybrid course, face-to-face, structured seat time is exchanged for online components. In such courses, students take more responsibility for their learning because they assume additional responsibility for learning more of the course material on their own. Thus, self-regulated learning (SRL) behaviors have the potential to be useful for students to successfully navigate hybrid courses because the online components require exercise of more personal control over the autonomous learning situations inherent in hybrid courses. Self-regulated learning theory includes three components: metacognition, motivation, and behavioral actions. In the current study, this theoretical framework is used to examine how inducing self-regulated learning activities among students taking a hybrid course influence performance in a community college science course. The intervention for this action research study consisted of a suite of activities that engage students in self-regulated learning behaviors to foster student performance. The specific SRL activities included predicting grades, reflections on coursework and study efforts in course preparation logs, explanation of SRL procedures in response to a vignette, photo ethnography work on their personal use of SRL approaches, and a personalized study plan. A mixed method approach was employed to gather evidence for the study. Results indicate that community college students use a variety of self-regulated learning strategies to support their learning of course material. Further, engaging community college students in learning reflection activities appears to afford some students with opportunities to refine their SRL skills and influence their learning. The discussion focuses on integrating the quantitative and qualitative

    Nanoscale science and technology (NST) is an important new field in modern science. In the current study, we seek to answer the question: 'What are the essential concepts of NST that should be taught in high school'? A 3-round Delphi study methodology was applied based on 2 communities of experts in nanotechnology research and science education. Eight essential concepts in NST were identified. Each concept is accompanied by its explanation, definition, importance and includes subcategories that compose it. Three concepts emerged in the Delphi study, which were not identified before: functionality, classification of nanomaterials, and the making of nanotechnology. Differences between the concepts suggested by the 2 communities of experts were found. The results of this study serve as a tool to examine different nanotechnology programs that were reported thus far and to make recommendations for designing a NST program for high school students that includes the essential concepts.

    Mcnutt, Ralph L., Jr.

    1988-01-01

    The Voyager Plasma Science (PLS) instrument is capable of returning integral (DC) current measurements, similar in some respects to measurements made with a Langmuir probe or a retarding potential analyzer, although there are significant differences. The integral measurements were made during a calibration sequence in the solar wind, during Cruise Science Maneuvers, and within the magnetospheres of Jupiter and Saturn by Voyager 1. After the failure of the PLS experiment following the Saturn encounter, that instrument was placed in the DC return mode returning possibly usable data from early 1981 through early 1985. The DC return measurements are difficult to interpret and are above threshold values only for relatively large fluxes; the determination of the measured current level is dependent on the operating temperature of the preamplifiers which further complicates the interpretation. Nevertheless, these measurements can be used to determine the efficiency of the suppressor grid at preventing the loss of secondary electrons off the collector plate. Some DC return measurements have been invaluable in aiding in the interpretation of some electron plasma measurements not previously understood. It is found that electron spectra can be significantly modified by the presence of second generation secondary electrons produced by either first generation secondaries or photoelectrons on the support ring of the negative high voltage modulator grid within the instrument housing.

    Decision-makers in every sector and region of the United States are seeking actionable science-based information to help them understand and manage their climate-related risks. Translating data, tools and information from the domain of climate science to the domains of municipal, social, and economic decision-making raises complex questions—e.g., how to communicate causes and impacts of climate variability and change; how to show projections of plausible future climate scenarios; how to characterize and quantify vulnerabilities, risks, and opportunities facing communities and businesses; and how to make and implement "win-win" adaptation plans. These are the types of challenges being addressed by a public-private partnership of federal agencies, academic institutions, non-governmental organizations, and private businesses that are contributing to the development of the U.S. Climate Resilience Toolkit (toolkit.climate.gov), a new website designed to help people build resilience to extreme events caused by both natural climate variability and long-term climate change. The site's Climate Explorer is designed to help people understand potential climate conditions over the course of this century. It offers easy access to downloadable maps, graphs, and data tables of observed and projected temperature, precipitation and other decision-relevant climate variables dating back to 1950 and out to 2100. Of course, climate change is only one of many variables affecting decisions about the future so the Toolkit also ties climate information to a wide range of other relevant tools and information to help users to explore their vulnerabilities and risks. In this session, we will describe recent enhancements to the Toolkit, lessons learned from user engagements, and evidence that our approach of coupling scientific information with actionable decision-making processes is helping Americans build resilience to climate-related impacts.

    2010-12-01

    contributed by colleagues to create personalized, annotated collections of resources best suited to address the needs of the students in their classroom. Teachers can see the resources that their colleagues are using to customize their instruction, and share their ideas about the suitability of resources for different learners or learning styles through the use of tags and annotations thus creating a community of practice in support of differentiated instruction. A field trial involving 124 middle and high school Earth science teachers in a large urban school district was conducted in the 2009-2010 academic year, accompanied by a mixed-method research and evaluation study to investigate the impact of the use of this system on teacher beliefs and practice, and student learning. This presentation will include a demonstration of the system as well as discuss the results of the research thus far.

  2. Persistence of community college engineering science students: The impact of selected cognitive and noncognitive characteristics

    Science.gov (United States)

    Chatman, Lawrence M., Jr.

    If the United States is to remain technologically competitive, persistence in engineering programs must improve. This study on student persistence employed a mixed-method design to identify the cognitive and noncognitive factors which contribute to students remaining in an engineering science curriculum or switching from an engineering curriculum at a community college in the northeast United States. Records from 372 students were evaluated to determine the characteristics of two groups: those students that persisted with the engineering curriculum and those that switched from engineering; also, the dropout phenomenon was evaluated. The quantitative portion of the study used a logistic regression analyses on 22 independent variables, while the qualitative portion of the study used group interviews to investigate the noncognitive factors that influenced persisting or switching. The qualitative portion of the study added depth and credibility to the results from the quantitative portion. The study revealed that (1) high grades in first year calculus, physics and chemistry courses, (2) fewer number of semesters enrolled, (3) attendance with full time status, and (4) not participating in an English as a Second Language (ESL) program were significant variables used to predict student persistence. The group interviews confirmed several of these contributing factors. Students that dropped out of college began with (1) the lowest levels of remediation, (2) the lowest grade point averages, and (3) the fewest credits earned.

    Sullivan, Ivy Aleta

    The purpose of this qualitative research investigates the influence of reading and writing to facilitate learning in science. Another purpose is to study the effect of constructivist teaching practices and cooperative learning to attain conceptual change among community college students in a Human Anatomy and Physiology I course. The affective dimension of learning anatomy and physiology through reading and writing was studied by examining the students' attitudes and personal beliefs expressed in their essays. This research combined several methods to engage the learner: reading an article of their choice from the "Vital Signs" series, writing an essay on the article read, collaborative group discussions, and critique of essay. The reading component of the study utilized the "Vital Signs" series from Discover magazine. The students then wrote essays using guide questions provided by the researcher. The essays were shared during the collaboration and critique session when students are in their "base groups." Reading and writing facilitates adult learners conceptual change in a human anatomy and physiology course through the linking of concepts to previous experiences, whether personal or previously studied materials. The positive effects of cooperative learning on minds-on construction of knowledge on adult learners' attitudes toward reading and writing about human anatomy and physiology were expressed at the focus group interviews. The choice of reading materials, working with peers, and freedom to express personal beliefs regarding the medically related articles positively influenced the adult learners' interest in learning human anatomy and physiology.

    The science of meteorology is full of duplicated effort. Actions such as reading in data, quality control and performing retrievals is repeated across institutions and while the traditional publication process helps in jumpstarting the development process details can be, some times deliberately, vague. Free and open software, specifically community software projects that are open to new contributions can help to alleviate this problem. This presentation will outline a growing international collaboration on the development of software for the reading, processing, retrieval from and output of weather radar data. Developers of the Python ARM Radar Toolkit, the Wradlib software package and the BALTRAD have been collaborating in order to improve the intercompatibility of the contributed code. This effort, coupled with running courses in open source software and sustainable programming practices is aimed at helping users cut through work that has been done before and get to using weather radar data to improve our understanding of the atmosphere and help decision makers make the best use of radar data. This will be an example driven presentation, code will be shown and examples worked through to give the audience a flavor of how work can be done with the various projects.

    Full Text Available Objective: The objectives of the present formative research were to explore the medical undergraduates’ study problems and their perceptions about various teaching approaches in currently practiced teaching curriculum of Community Medicine. Material and Methods: The present formative research was undertaken at Dr. Sushila Nayar School of Public Health incorporating Department of Community Medicine, Mahatma Gandhi Institute of Medical Sciences, Sewagram. The respondents were 17 (26.5% conveniently selected final year exam appearing medical undergraduates from 2004 regular batch of 64 students. A triangulation of qualitative research methods like free listing, pile sort exercise and a Focus Group Discussion (FGD were used. A two dimensional scaling and hierarchical cluster analysis was completed with the pile sort data. The data was analyzed by using software Anthropac 4.98.1/X software. Results: The medical undergraduates could understand the topics like Integrated Management of Neonatal and Childhood (IMNCI, Primary Health Care (PHC, cold chain system for vaccines, immunization and health education, dietary survey and cluster survey method taught in the community based camp approaches. Students found it difficult to comprehend the core of subject from the scattered lecture series over a long teaching period, especially using lengthy over head projector/liquid crystal display presentations. The major problems encountered in studying the subject of Community Medicine were difficulty in understanding the concepts of biostatistics, confusions due to apparently similar text in National Health Programs and difficulty to recall disease statistics due to vast syllabus. Conclusions: Students perceived the community based camp approach of teaching as a best method to understand the subject, which is an integration of task oriented assignments, integration of social sciences within medical domain and active community involvement. Hence, the community

    The idea to create advanced platforms for the Earth Observation community, where the users can find data but also state-of-art algorithms, processing tools, computing facilities, and instruments for dissemination and sharing, has been launched several years ago. The initiatives developed in this context have been supported firstly by the Framework Programmes of European Commission and the European Space Agency (ESA) and, progressively, by the Copernicus programme. In particular, ESA created and supported the Grid Processing on Demand (G-POD) environment, where the users can access to advanced processing tools implemented in a GRID environment, satellite data and computing facilities. All these components are located in the same datacentre to significantly reduce and make negligible the time to move the satellite data from the archive. From the experience of G-POD was born the idea of ESA to have an ecosystem of Thematic Exploitation Platforms (TEP) focused on the integration of Ground Segment capabilities and ICT technologies to maximize the exploitation of EO data from past and future missions. A TEP refers to a computing platform that deals with a set of user scenarios involving scientists, data providers and ICT developers, aggregated around an Earth Science thematic area. Among the others, the Geohazards Exploitation Platform (GEP) aims at providing on-demand and systematic processing services to address the need of the geohazards community for common information layers and to integrate newly developed processors for scientists and other expert users. Within GEP, the community benefits from a cloud-based environment, specifically designed for the advanced exploitation of EO data. A partner can bring its own tools and processing chains, but also has access in the same workspace to large satellite datasets and shared data processing tools. GEP is currently in the pre-operations phase under a consortium led by Terradue Srl and six pilot projects concerning

    This forum discusses the issue of `othering' and how intersectionality is a useful analytical framework for understanding the students' immigrant experiences in, and out of, the science classroom. We use a feminist perspective to discuss Minjung's study because gender is a key aspect of one's identity other aspects such as race, religion, socio-economic status, and age have assumed a significant status in gender studies. Lastly we examine the supports and barriers that cliques can produce and propose the importance of building a learning community in the science classroom to engage all students.

    Monocyte chemoattractant protein (MCP)-1 increases in the serum of immunocompetent patients with community-acquired pneumonia (CAP). However, the correlation between the circulating level of MCP-1 and severity of CAP remains unclear. This study investigated differential changes in the plasma MCP-1 levels of patients with CAP before and after an antibiotic treatment and further analyzes the association between the CAP severity and MCP-1 levels. We measured the plasma MCP-1 levels of 137 patients with CAP and 74 healthy controls by using a commercial enzyme-linked immunosorbent assay. Upon initial hospitalization, Acute Physiology and Chronic Health Evaluation II (APACHE II); confusion, urea level, respiratory rate, blood pressure, and age of >64 years (CURB-65); and pneumonia severity index (PSI) scores were determined for assessing the CAP severity in these patients. The antibiotic treatment reduced the number of white blood cells (WBCs) and neutrophils as well as the level of C-reactive protein (CRP) and MCP-1. The plasma MCP-1 level, but not the CRP level or WBC count, correlated with the CAP severity according to the PSI (r = 0.509, p < 0.001), CURB-65 (r = 0.468, p < 0.001), and APACHE II (r = 0.360, p < 0.001) scores. We concluded that MCP-1 levels act in the development of CAP and are involved in the severity of CAP.

    2015-04-01

    The Global Earth Observation System of Systems (GEOSS) developed by the Group on Earth Observations (GEO) aims to provide practice-relevant knowledge in support of decision making in a wide range of societal benefit areas. Generating this practice-relevant knowledge based on Earth observations, socio-economic data and models often depends on research, and utilization of the societal benefits of EOs requires the involvement of science and research communities. Building a GEOSS responding to the needs of a wide range of users necessitates contributions from many science and technology (S&T) communities. In particular, a strong engagement of science and technology (S&T) communities in both the development and use of GEOSS is necessary to address the complex issues associated with the on-going transition out of the Holocene. S&T support is needed to improve interoperability between global observing, modeling, and information systems; to enable data integration across disciplinary boundaries; to facilitate data sharing, archiving, dissemination, and reanalysis; to optimize the recording of observations, assimilation of data into models, and generation of data products; to enhance the value of observations from individual observing systems through their integration in the SBAs; and to harmonize well-calibrated, highly accurate, stable, sustained in-situ and satellite observations of the same variable recorded by different sensors and different agencies. Consequently, the GEO Work Plan includes several Tasks focusing on outreach to S&T communities, and most of the GEO Community of Practice have a strong S&T component. The GEOSS S&T Stakeholder Network facilitates input from S&T communities to GEO. Infrastructure serving and linking S&T users communities and GEOSS has been developed and is integrated into a GEOSS S&T Service Suite (GSTSS). The GSTSS has several outreach components for the demonstration of GEOSS and its value for S&T communities, and for services supporting

    The advancement of Laser-Plasma Accelerators (LPA) requires systematic studies with ever increasing precision and reproducibility. A key component of such a research endeavor is a facility that provides reliable, well characterized laser sources, flexible target systems, and comprehensive diagnostics of the laser pulses, the interaction region, and the produced electron beams. The Berkeley Lab Laser Accelerator (BELLA), a PW laser facility, now routinely provides high quality focused laser pulses for high precision experiments. A description of the commissioning process, the layout of the laser systems, the major components of the laser and radiation protection systems, and a summary of early results are given. Further scientific plans and highlights of operational experience that serve as the basis for transition to a collaborative research facility in high-peak power laser-plasma interaction research are reviewed.

  16. Citizen Science for Post-disaster Sustainable Community Development in Ecologically Fragiel Regions - A Case from China

    Liu, Wei; Ming, Meng; Lu, Ye; Jin, Wei

    2016-04-01

    The world's mountains host some of the most complex, dynamic, and diverse ecosystems and are also hotspots for natural disasters, such as earthquake, landslide and flood. One factor that limits the mountain communities to recover from disasters and pursue sustainable development is the lack of locally relevant scientific knowledge, which is hard to gain from global and regional scale observations and models. The rapid advances in ICT, computing, communication technologies and the emergence of citizen science is changing the situation. Here we report a case from Sichuan Giant Panda Sanctuary World Natural Heritage in China on the application of citizen science in a community reconstruction project. Dahe, a mountainous community (ca. 8000 ha in size) is located covering part of the World Heritage's core and buffer zones, with an elevation range of 1000-3000 meters. The community suffered from two major earthquakes of 7.9 and 6.9 Mw in 2008 and 2013 respectively. Landslides and flooding threat the community and significantly limit their livelihood options. We integrated participatory disaster risk mapping (e.g., community vulnerability and capacity assessment) and mobile assisted natural hazards and natural resources mapping (e.g., using free APP GeoODK) into more conventional community reconstruction and livelihood building activities. We showed that better decisions are made based on results from these activities and local residents have a high level of buy-in in these new knowledge. We suggest that initiatives like this, if successfully scale-up, can also help generate much needed data and knowledge in similar less-developed and data deficient regions of the world.

    2000-10-01

    This study explored the academic experiences of two groups of first-year students in university, one in the arts and one in the science, who participated in a residential-based learning community program. Using qualitative and critical analysis of in-depth student interviews conducted over a fall and winter semester, I constructed their world as implied from their stories and narratives. From this vantage point, I investigated how students as novice learners negotiated their role as learners; the belief systems they brought with them to minimize academic risk; their coping strategies in a 12 week semestered system; and the tacit theories they acquired within their day-to-day educational experiences. A number of themes emerged from the research: students intentionally minimizing faculty contact until they developed 'worthiness'; learning as 'teacher pleasing'; disciplinary learning differences between the arts and sciences students; and a grade orientation that influenced what and how students learned. Within the broader political, ideological, and cultural framework of the university, I identified student patterns of accommodation, resistance, silence and submission in negotiating their roles as learners. By critiquing the academic side of university life as students experienced it and lived it as a community of learners, I exposed the tensions, contradictions, and paradoxes that emerged. I revealed the points of disjuncture that came from competing discourses within the university for these students: the discourse of community, the discourse of collective harmony, and the discourse of the market place.

    2008-10-01

    There is a need to generate magnetic fields both above and below 1 megagauss (100 T) with compact generators for laser-plasma experiments in the Beamlet and Petawatt test chambers for focused research on fundamental properties of high energy density magnetic plasmas. Some of the important topics that could be addressed with such a capability are magnetic field diffusion, particle confinement, plasma instabilities, spectroscopic diagnostic development, material properties, flux compression, and alternate confinement schemes, all of which could directly support experiments on Z. This report summarizes a two-month study to develop preliminary designs of magnetic field generators for three design regimes. These are, (1) a design for a relatively low-field (10 to 50 T), compact generator for modest volumes (1 to 10 cm3), (2) a high-field (50 to 200 T) design for smaller volumes (10 to 100 mm3), and (3) an extreme field (greater than 600 T) design that uses flux compression. These designs rely on existing Sandia pulsed-power expertise and equipment, and address issues of magnetic field scaling with capacitor bank design and field inductance, vacuum interface, and trade-offs between inductance and coil designs.

    Seeing Understanding and Teaching: Climate Change in Denali is a four-day immersive teacher professional development course held in Denali National Park. Developed through three partner organizations, the course aims to develop teachers' skills for integrating climate change content into their classrooms. This presentation aims to share tangible best practices for linking researchers and teachers in the field, through four years of experience in program delivery and reported through a published external evaluation. This presentation will examine the key aspects of a successful connection between teachers, researchers, science, and classrooms: (1) Inclusion of teacher leaders, (2) dedicated program staff, (3) workshop community culture, and will expose barriers to this type of collaboration including (1) differences in learning style, (2) prior teaching experience, (3) existing/scaffolding understanding of climate change science, and (4) accessibility of enrollment and accommodations for the extended learning experience. Presentation Content Examples:Participants overwhelmingly value the deep commitment this course has to linking their field experience to the classroom attributing to the role of a teacher-leader; an expert science teacher with first-hand field research experience in the polar regions. The goal of including a teacher-leader is to enhance translatability between fieldwork and the classroom. Additionally, qualitative aspects of the report touches on the intangible successes of the workshop such as: (1) the creation of a non-judgmental learning atmosphere, (2) addressing accessibility to science learning tools in rural and under-served communities, (3) defining successful collaboration as making meaning together through exploratory questioning while in the field (4) discussed the social and cultural implications of climate change, and the difficulty of navigating these topics in educational and/or multicultural spaces.

    Laser-plasma interactions in the novel regime of relativistically induced transparency (RIT) have been harnessed to generate intense ion beams efficiently with average energies exceeding 10 MeV/nucleon (>100 MeV for protons) at "table-top" scales in experiments at the LANL Trident Laser. By further optimization of the laser and target, the RIT regime has been extended into a self-organized plasma mode. This mode yields an ion beam with much narrower energy spread while maintaining high ion energy and conversion efficiency. This mode involves self-generation of persistent high magnetic fields (˜104 T, according to particle-in-cell simulations of the experiments) at the rear-side of the plasma. These magnetic fields trap the laser-heated multi-MeV electrons, which generate a high localized electrostatic field (˜0.1 T V/m). After the laser exits the plasma, this electric field acts on a highly structured ion-beam distribution in phase space to reduce the energy spread, thus separating acceleration and energy-spread reduction. Thus, ion beams with narrow energy peaks at up to 18 MeV/nucleon are generated reproducibly with high efficiency (≈5%). The experimental demonstration has been done with 0.12 PW, high-contrast, 0.6 ps Gaussian 1.053 μm laser pulses irradiating planar foils up to 250 nm thick at 2-8 × 1020 W/cm2. These ion beams with co-propagating electrons have been used on Trident for uniform volumetric isochoric heating to generate and study warm-dense matter at high densities. These beam plasmas have been directed also at a thick Ta disk to generate a directed, intense point-like Bremsstrahlung source of photons peaked at ˜2 MeV and used it for point projection radiography of thick high density objects. In addition, prior work on the intense neutron beam driven by an intense deuterium beam generated in the RIT regime has been extended. Neutron spectral control by means of a flexible converter-disk design has been demonstrated, and the neutron beam has

    The purpose of the Travel Grant Program is to increase the awareness of plasma research. The new results and techniques of plasma research in fusion plasmas, plasma processing space plasmas, basic plasma science, etc, have broad applicability throughout science. The benefits of these results are limited by the relatively low awareness and appreciation of plasma research in the larger scientific community. Whereas spontaneous interactions between plasma scientists and other scientists are useful, a focused effort in education and outreach to other scientists is efficient and is needed. The academic scientific community is the initial focus of this effort, since that permits access to a broad cross-section of scientists and future scientists including undergraduates, graduate students, faculty, and research staff.

    Gioe, Lisa M.

    This dissertation explored the beliefs of five members of a nascent professional learning community for middle school science teachers over the first semester of its existence. A professional learning community is a place for colleagues to voice and hear beliefs, and is particularly conducive to fostering the development of one's own beliefs. Professional learning communities have the potential to serve as an effective method of professional development for teachers, with the ultimate goal of identifying and implementing practices that support student learning. In my research study, the creation of a professional learning community served as a medium for bringing science teachers from a large, traditional NYC public middle school, used to working and planning in isolation, together for the first time to talk about their beliefs and practice. I used a qualitative approach to collect and analyze my case study data. I collected transcripts of teacher interview data prior to their participation in the PLC; and transcript data from five 45-minute professional learning community discussions. The strategies I employed to analyze these data included reviews of analytic notes, reviews of transcripts, the development of preliminary codes, and coding and categorizing data to identify emerging themes. Drawing from the literature on professional learning communities and reflection on action, my research identified a sequence of stages unique to nascent professional learning communities that are vital to the development of a PLC forum that will be conducive to discussion about student learning objectives and outcomes. In addition, this research study acknowledges both independent and collaborative teacher reflection on action as effective methods for reported teacher growth and change in practice. The data collected on the nascent PLC within its particular research study has implications for identifying the conditions that support the development of good PLCs and the attributes

    This three year study of P-12 professional development is grounded in sociocultural theories that hold that building knowledge and relationships among individuals from different cultural backgrounds entails joint activity toward common goals and cultural dialogues mediated by cultural translators. Sixty P-12 pre and in-service teachers in a year long interdisciplinary science curriculum course shared the goal of developing culturally relevant, standards-based science curricula for Native Hawai'ian students. Teachers and Native Hawai'ian instructors lived and worked together during a five day culture-science immersion in rural school and community sites and met several times at school, university, and community sites to build knowledge and share programs. Teachers were deeply moved by immersion experiences, learned to connect cultural understandings, e.g., a Hawai'ian sense of place and curriculum development, and highly valued collaborating with peers on curriculum development and implementation. The study finds that long term professional development providing situated learning through cultural immersion, cultural translators, and interdisciplinary instruction supports the establishment of communities of practice in which participants develop the cross-cultural knowledge and literacy needed for the development of locally relevant, place and standards-based curricula and pedagogy.

    Physical inactivity across the lifespan remains a public health issue for many developed countries. Inactivity has contributed considerably to the pervasiveness of lifestyle diseases. Government, national and local agencies and organizations have been unable to systematically, and in a coordinated way, translate behavioral research into practice that makes a difference at a population level. One approach for mobilizing multi-level efforts to improve the environment for physical activity is to engage in a process of citizen science. Citizen Science here is defined as a participatory research approach involving members of the public working closely with research investigators to initiate and advance scientific research projects. However, there are no common measures or protocols to guide citizen science research at the local community setting. We describe overarching categories of constructs that can be considered when designing citizen science projects expected to yield multi-level interventions, and provide an example of the citizen science approach to promoting PA. We also recommend potential measures across different levels of impact. Encouraging some consistency in measurement across studies will potentially accelerate the efficiency with which citizen science participatory research provides new insights into and solutions to the behaviorally-based public health issues that drive most of morbidity and mortality. The measures described in this paper abide by four fundamental principles specifically selected for inclusion in citizen science projects: feasibility, accuracy, propriety, and utility. The choice of measures will take into account the potential resources available for outcome and process evaluation. Our intent is to emphasize the importance for all citizen science participatory projects to follow an evidence-based approach and ensure that they incorporate an appropriate assessment protocol. We provided the rationale for and a list of contextual factors

    Accurate forecasts of broken cloud fields and their associated impact on the downwelling solar irradiance has remained a challenge to the renewable energy industry. Likewise, shallow cumulus play an important role in the Earth's radiation budget and hydrologic cycle and are of interest to the weather forecasting and climate science communities. The main challenge associated with predicting these clouds are their relatively small size (on the order of a kilometer or less) relative to the model grid spacing. Recently, however, there have been significant efforts put into improving forecasts of shallow clouds and the associated temporal and spatial variability of the solar irradiance that they induce. As an example of these efforts, we will describe recent modifications to the standard Kain-Fritsch parameterization as applied within the Weather Research and Forecasting (WRF) model that are designed to improve predictions of the macroscale and microscale structure of shallow cumulus. These modifications are shown to lead to a realistic increase in the simulated cloud fraction and associated decrease in the solar irradiance. We will evaluate our results using data collected at the Department of Energy's Atmospheric Radiation Measurement (ARM) Southern Great Plains site, which is located in north-central Oklahoma. Our team has analyzed over 5 years of data collected at this site to document the macroscale structure of the clouds (including cloud fraction, cloud-base and cloud-top height) as well as their impact on the downwelling shortwave and longwave irradiance. One particularly interesting impact of shallow cumuli is the enhancement of the diffuse radiation, such that during periods in which the sun is not blocked, the observed irradiance can be significantly larger than the corresponding clear sky case. To date, this feature is not accurately represented by models that apply the plane-parallel assumption applied in the standard radiation parameterizations.

    Arctic Science Summit Week (ASSW) is the annual gathering of international organizations engaged in supporting and facilitating Arctic research. The University of Alaska Fairbanks hosted the 2016 ASSW and several associated side meetings that attracted over 1,000 participants from 30 nations. Unlike most scientific conferences, a strategic communication plan was developed to engage key audiences and stakeholder groups to achieve the goals of (1) advancing stakeholder collaboration in the Arctic and (2) increasing awareness of America's role in international collaboration in the Arctic. Beyond ensuring that the conference was well attended and participants had the information to have a successful meeting, the communication plan also included several objectives to engage the broader community in opportunities to benefit from subject area experts attending the conference and learn about Arctic science. The strategic communication effort was instrumental in the success of the conference and several community events. However, introducing strategic communication into a process and to people with no prior experience also added some challenges. In order to be successful, we had to develop a shared understanding of the strategic communication process and discipline-specific terms with our colleagues in the biophysical sciences. The outcomes and lessons that will be shared in this poster are valuable to anyone in science or environmental communication, planning conference communications, and/or those who are adopting strategic communication approaches where they haven't previously existed.

  13. Knowledge, language and subjectivities in a discourse community: Ideas we can learn from elementary children about science

    2000-10-01

    In light of continuing poor performance by American students in school science, feminists and sociocultural researchers have demonstrated that we need to look beyond content to address the science needs of all school children. In this study I examined issues of discourse norms, knowledge, language and subjectivities (meaning personal and social observations and characteristics) in elementary science. Over a two-year period, I used an interpretive methodological approach to investigate science experiences in two first-second and second grade classrooms. I first established some of the norms and characteristics of the discourse communities through case studies of new students attempting to gain entry to whole class conversations. I then examined knowledge, a central focus of science education addressed by a variety of theoretical approaches. In these classrooms students co-constructed and built knowledge in their whole class science conversations sometimes following convergent (similar knowledge) and, at other times, divergent (differing knowledge) paths allowing for broader discourse. In both paths, there was gendered construction of knowledge in which same gender students elaborated the reasoning of previous speakers. In conjunction with these analyses, I examined what knowledge sources the students used in their science conversations. Students drew on a variety of informal and formal knowledge sources including personal experiences, other students, abstract logic and thought experiments, all of which were considered valid. In using sources from both in and out of school, students' knowledge bases were broader than traditional scientific content giving greater access and richness to their conversations. The next analysis focused on students' use of narrative and paradigmatic language forms in the whole class science conversations. Traditionally, only paradigmatic language forms have been used in science classrooms. The students in this study used both narrative and

    Platelet-rich plasma (PRP) has been advocated for the biological augmentation of tissue healing and regeneration through the local introduction of increased levels (above baseline) of platelets and their associated bioactive molecules. In theory, the increased levels of autologous growth factors and secretory proteins provided by the concentrated platelets may enhance the wound healing process, especially in degenerative tissues or biologically compromised individuals. Although PRP has been increasingly utilized in the treatment of a variety of sports-related injuries, improvements in healing and clinical outcomes have not been universally reported. One reason for this may be the fact that all PRP preparations are not the same. Variations in the volume of whole blood taken, the platelet recovery efficacy, the final volume of plasma in which the platelets are suspended, and the presence or absence of white blood cells, and the addition of exogenous thrombin to activate the platelets or calcium chloride to induce fibrin formation, can all affect the character and potential efficacy of the final PRP product. This article will review the basic principles involved in creating PRP and examine the potential basic scientific significance of the individual blood components contained in the various forms of PRP currently used in sports medicine.

    This article describes a pilot study evaluating the sensitivity of Indigenous community health to climate change impacts on Salish Sea shorelines (Washington State, United States and British Columbia, Canada). Current climate change assessments omit key community health concerns, which are vital to successful adaptation plans, particularly for Indigenous communities. Descriptive scaling techniques, employed in facilitated workshops with two Indigenous communities, tested the efficacy of ranking six key indicators of community health in relation to projected impacts to shellfish habitat and shoreline archaeological sites stemming from changes in the biophysical environment. Findings demonstrate that: when shellfish habitat and archaeological resources are impacted, so is Indigenous community health; not all community health indicators are equally impacted; and, the community health indicators of highest concern are not necessarily the same indicators most likely to be impacted. Based on the findings and feedback from community participants, exploratory trials were successful; Indigenous-specific health indicators may be useful to Indigenous communities who are assessing climate change sensitivities and creating adaptation plans.

    Nuclear reaction measurements are performed at the National Ignition Facility in a high energy density plasma environment by adding target materials to the outside of the hohlraum thermo-mechanical package on an indirect-drive exploding pusher shot. Materials are activated with 14.1-MeV neutrons and the post-shot debris is collected via the Solid Radiochemistry diagnostic, which consists of metal discs fielded 50 cm from target chamber center. The discs are removed post-shot and analyzed via radiation counting and mass spectrometry. Results from a shot using Nd and Tm foils as targets are presented, which indicate enhanced collection of the debris in the line of sight of a given collector. The capsule performance was not diminished due to the extra material. This provides a platform for future measurements of nuclear reaction data through the use of experimental packages mounted external to the hohlraum.

    This report summarizes the work of the National Fusion Collaboratory (NFC) Project to develop a persistent infrastructure to enable scientific collaboration for magnetic fusion research. The original objective of the NFC project was to develop and deploy a national FES Grid (FusionGrid) that would be a system for secure sharing of computation, visualization, and data resources over the Internet. The goal of FusionGrid was to allow scientists at remote sites to participate as fully in experiments and computational activities as if they were working on site thereby creating a unified virtual organization of the geographically dispersed U.S. fusion community. The vision for FusionGrid was that experimental and simulation data, computer codes, analysis routines, visualization tools, and remote collaboration tools are to be thought of as network services. In this model, an application service provider (ASP provides and maintains software resources as well as the necessary hardware resources. The project would create a robust, user-friendly collaborative software environment and make it available to the US FES community. This Grid's resources would be protected by a shared security infrastructure including strong authentication to identify users and authorization to allow stakeholders to control their own resources. In this environment, access to services is stressed rather than data or software portability.

  20. Developmental/remedial sciences at community colleges in five states in the central part of the United States

    Science.gov (United States)

    Paramore, Tricia L.

    Phipps (1998) emphasized interinstitutional collaboration among colleges to share and replicate best practices and ideas as a strategy to improve the effectiveness of developmental/remedial education, but Johnson (2001) noted a lack of communication between science educators and developmental educators. The purposes of this mixed methods study were (a) to identify and examine the characteristics of developmental/remedial sciences as it existed in the 2006-2007 academic year in terms of organization, structure, instructional practices, and curriculum as offered at community colleges in five states in the central part of the United States; and (b) to develop a set of guidelines for community college faculty and administrators to use in making decisions about whether or not to offer developmental/remedial sciences and identify the general steps to follow in implementation. The study was conducted in four phases which involved two surveys, subsequent interviews with leaders at three institutions selected for case study, and guideline development. Developmental/remedial sciences were offered at few institutions. At those institutions where they were offered, however, nearly half offered courses and multiple support services, but did not define their offerings as a program. Some developmental education best practices were adopted (such as integrating study skills with science content in courses and using a variety of instructional strategies), but many, including goals and assessment, were omitted. Interviewees indicated the need for developmental/remedial sciences would continue in the future. Guidelines to use in determining whether to offer developmental/remedial sciences included the following: (1) adopt an attitude of quality improvement; (2) look to faculty as a #1 resource; (3) assess what is currently offered in the sciences and ask if it works; (4) know what you are remediating; (5) start a conversation between the academic department and support services staff

    2008-12-01

    Research libraries provide a set of core services to the scholarly and educational communities. This includes: information acquisition, synthesis, navigation, discovery, dissemination, interpretation, presentation, understanding and archiving. Researchers across the science disciplines and increasingly in multi disciplinary projects are producing massive amounts of data, and they seek the infrastructure, the strategies and the partnerships that will enable rigorous and sustained tools for extraction, distribution, collaboration, application and permanent availability. This paper will address the role of the research library from three perspectives. First, the view of scientific datasets as information assets that would benefit from traditional library collection development practice will be explored. Second, the agenda on e-science developed by the Association of Research Libraries will be outlined with a focus on the need for policy and standards development, for resources assessment and allocation, for new approaches to the preparation of the library professional, and library leadership in campus planning and innovative collaborations for research cyberinfrastructure. And third, the responses to the call for proposals from the National Science Foundation's DataNet program will be analyzed and the role of the research library in these project plans will be summarized as an indicator of the expanding responsibility of the library for research data stewardship.

  2. Challenges in conducting community-driven research created by differing ways of talking and thinking about science: a researcher's perspective.

    2013-01-01

    Increasingly, health scientists are becoming aware that research collaborations that include community partnerships can be an effective way to broaden the scope and enhance the impact of research aimed at improving public health. Such collaborations extend the reach of academic scientists by integrating a variety of perspectives and thus strengthening the applicability of the research. Communication challenges can arise, however, when attempting to address specific research questions in these collaborations. In particular, inconsistencies can exist between scientists and community members in the use and interpretation of words and other language features, particularly when conducting research with a biomedical component. Additional challenges arise from differing perceptions of the investigative process. There may be divergent perceptions about how research questions should and can be answered, and in expectations about requirements of research institutions and research timelines. From these differences, misunderstandings can occur about how the results will ultimately impact the community. These communication issues are particularly challenging when scientists and community members are from different ethnic and linguistic backgrounds that may widen the gap between ways of talking and thinking about science, further complicating the interactions and exchanges that are essential for effective joint research efforts. Community-driven research that aims to describe the burden of disease associated with Helicobacter pylori infection is currently underway in northern Aboriginal communities located in the Yukon and Northwest Territories, Canada, with the goal of identifying effective public health strategies for reducing health risks from this infection. This research links community representatives, faculty from various disciplines at the University of Alberta, as well as territorial health care practitioners and officials.

    Fei Song

    Full Text Available OBJECTIVES: Apolipoproteins have recently been implicated in the etiology of Alzheimer's disease (AD. In particular, Apolipoprotein J (ApoJ or clusterin has been proposed as a biomarker of the disease at the pre-dementia stage. We examined a group of apolipoproteins, including ApoA1, ApoA2, ApoB, ApoC3, ApoE, ApoH and ApoJ, in the plasma of a longitudinal community based cohort. METHODS: 664 subjects (257 with Mild Cognitive Impairment [MCI] and 407 with normal cognition, mean age 78 years, from the Sydney Memory and Aging Study (MAS were followed up over two years. Plasma apolipoprotein levels at baseline (Wave 1 were measured using a multiplex bead fluorescence immunoassay technique. RESULTS: At Wave 1, MCI subjects had lower levels of ApoA1, ApoA2 and ApoH, and higher levels of ApoE and ApoJ, and a higher ApoB/ApoA1 ratio. Carriers of the apolipoprotein E ε4 allele had significantly lower levels of plasma ApoE, ApoC3 and ApoH and a significantly higher level of ApoB. Global cognitive scores were correlated positively with ApoH and negatively with ApoJ levels. ApoJ and ApoE levels were correlated negatively with grey matter volume and positively with cerebrospinal fluid (CSF volume on MRI. Lower ApoA1, ApoA2 and ApoH levels, and higher ApoB/ApoA1 ratio, increased the risk of cognitive decline over two years in cognitively normal individuals. ApoA1 was the most significant predictor of decline. These associations remained after statistically controlling for lipid profile. Higher ApoJ levels predicted white matter atrophy over two years. CONCLUSIONS: Elderly individuals with MCI have abnormal apolipoprotein levels, which are related to cognitive function and volumetric MRI measures cross-sectionally and are predictive of cognitive impairment in cognitively normal subjects. ApoA1, ApoH and ApoJ are potential plasma biomarkers of cognitive decline in non-demented elderly individuals.

  14. An Examination of the Processes of Student Science Identity Negotiation within an Informal Learning Community

    Mark, Sheron L.

    Scientific proficiency is important, not only for a solid, interdisciplinary educational foundation, but also for entry into and mobility within today's increasingly technological and globalized workplace, as well as for informed, democratic participation in society (National Academies Press, 2007b). Within the United States, low-income, ethnic minority students are disproportionately underperforming and underrepresented in science, as well as mathematics, engineering and other technology fields (Business-Higher Education Forum, 2011; National Assessment of Educational Progress, 2009). This is due, in part, to a lack of educational structures and strategies that can support low-income, ethnic minority students to become competent in science in equitable and empowering ways. In order to investigate such structures and strategies that may be beneficial for these students, a longitudinal, qualitative study was conducted. The 15 month study was an investigation of science identity negotiation informed by the theoretical perspectives of Brown's (2004) discursive science identities and Tan and Barton's (2008) identities-in-practice amongst ten high school students in an informal science program and employed an amalgam of research designs, including ethnography (Geertz, 1973), case study (Stake, 2000) and grounded theory (Glaser & Strauss, 1967). Findings indicated that the students made use of two strategies, discursive identity development and language use in science, in order to negotiate student science identities in satisfying ways within the limits of the TESJ practice. Additionally, 3 factors were identified as being supportive of successful student science identity negotiation in the informal practice, as well. These were (i) peer dynamics, (ii) significant social interactions, and (iii) student ownership in science. The students were also uncovered to be particularly open-minded to the field of STEM. Finally, with respect to STEM career development, specific

    Full Text Available Community gardens are heterogeneous environments that integrate environmental restoration, community activism, social interactions, cultural expression, and food security. As such, they provide a context for learning that addresses multiple societal goals, including a populace that is scientifically literate, practices environmental stewardship, and participates in civic life. Several theories are useful in describing the learning that occurs in community gardens, including those focusing on learning as acquisition of content by individuals, learning as interaction with other individuals and the environment and as increasingly skilled levels of participation in a community of practice, and social learning among groups of stakeholders leading to concerted action to enhance natural resources. In this paper, we use preliminary evidence from the Garden Mosaics intergenerational education program to suggest the potential for community gardens to foster multiple types of learning.

    In 2012, the School of Earth Sciences (SES) at Stanford University sponsored two summer undergraduate research programs. Here we describe these programs and efforts to build a cohesive research cohort among the programs' diverse participants. The two programs, the Stanford School of Earth Sciences Undergraduate Research (SESUR) Program and Stanford School of Earth Sciences Summer Undergraduate Research in Geoscience and Engineering (SURGE) Program, serve different undergraduate populations and have somewhat different objectives, but both provide students with opportunities to work on strongly mentored yet individualized research projects. In addition to research, enrichment activities co-sponsored by both programs support the development of community within the combined SES summer undergraduate research cohort. Over the course of 6 to 9 months, the SESUR Program engages Stanford undergraduates, primarily rising sophomores and juniors, with opportunities to deeply explore Earth sciences research while learning about diverse areas of inquiry within SES. Now in its eleventh year, the SESUR experience incorporates the breadth of the scientific endeavor: finding an advisor, proposal writing, obtaining funding, conducting research, and presenting results. Goals of the SESUR program include (1) providing a challenging and rewarding research experience for undergraduates who wish to explore the Earth sciences; (2) fostering interdisciplinary study in the Earth sciences among the undergraduate population; and (3) encouraging students to major or minor in the Earth sciences and/or to complete advanced undergraduate research in one of the departments or programs within SES. The SURGE Program, now in its second year, draws high performing students, primarily rising juniors and seniors, from 14 colleges and universities nationwide, including Stanford. Seventy percent of SURGE students are from racial/ethnic backgrounds underrepresented in STEM fields, and approximately one

    Many others in the fusion energy and advanced scientific computing communities participated in the development of this plan. The core planning team is grateful for their important contributions. This summary is meant as a quick overview the Fusion Simulation Program's (FSP's) purpose and intentions. There are several additional documents referenced within this one and all are supplemental or flow down from this Program Plan. The overall science goal of the DOE Office of Fusion Energy Sciences (FES) Fusion Simulation Program (FSP) is to develop predictive simulation capability for magnetically confined fusion plasmas at an unprecedented level of integration and fidelity. This will directly support and enable effective U.S. participation in International Thermonuclear Experimental Reactor (ITER) research and the overall mission of delivering practical fusion energy. The FSP will address a rich set of scientific issues together with experimental programs, producing validated integrated physics results. This is very well aligned with the mission of the ITER Organization to coordinate with its members the integrated modeling and control of fusion plasmas, including benchmarking and validation activities. [1]. Initial FSP research will focus on two critical Integrated Science Application (ISA) areas: ISA1, the plasma edge; and ISA2, whole device modeling (WDM) including disruption avoidance. The first of these problems involves the narrow plasma boundary layer and its complex interactions with the plasma core and the surrounding material wall. The second requires development of a computationally tractable, but comprehensive model that describes all equilibrium and dynamic processes at a sufficient level of detail to provide useful prediction of the temporal evolution of fusion plasma experiments. The initial driver for the whole device model will be prediction and avoidance of discharge-terminating disruptions, especially at high performance, which are a

    To describe the dimensions of organisational culture within a selection of community pharmacies. Community pharmacy in the New Zealand primary care sector which is partially government funded and currently undergoing major reform. Community pharmacy is under pressure to take on new roles, integrate within the wider primary care team and deliver the expectations of contemporary health policy. The mixed methods approach of concept mapping was undertaken with 10 representatives from six community pharmacies selected as case sites. The process was split into three parts (a) face to face brainstorming to generate statements describing culture, followed by (b) statement reduction, piloting and approval of statement list by participants, followed by (c) sorting the statements into 'like' groups. Multidimensional scaling analysis of participant sorting allows the development of discrete clusters of statements that describe aspects of organizational culture. A set of 105 statements were generated at the brainstorming meeting. Eight clusters of organisational culture resulted from participant sorting: leadership and staff management; valuing each other and the team; free thinking, fun and open to challenge; trusted behaviour; customer relations; focus on external integration; providing systematic advice; embracing innovation. Community pharmacy is under pressure to take on new roles and deliver and there is some evidence organisational culture of pharmacy may be a barrier. Our paper outlines the development of a survey instrument for describing organisational culture through Concept mapping, a tool borrowed from social sciences. This tool can be used for exploration of aspects of culture that may be important in the change management process for improving the effectiveness of community pharmacy as expected by contemporary primary health care policy.

    Full Text Available This article explores a debate (and its origins which is taking place around the issue of science popularization. Although the participants are all describing popularization in various ways, the heart is in what makes a good popularization. The notion of this has changed from the 19th century view, which called for a simple and easy - to - understand text, to a more modern view, which suggests a good popularization engages the reader emotionally. This discussion might also be seen in a context of a more profou nd debate of science experts versus general public and what science and scientific knowledge mean to each group. The exploration of this relationship suggests a shift in the role lay public plays in science.

    Less than a year ago, AGU had yet to explore the world of science blogging. Now AGU not only has three blogs of its own but also has launched the AGU Blogosphere, a network of independent Earth and space science blogs hosted under the Union's umbrella. The new network of blogs, composed of seven external blogs written by scientists and covering topics including planetary exploration, landslides, Washington, D. C.-area geology, volcanoes, climate change, and more, can now be found together with the in-house blogs at http://blogs.agu.org. It's been a fast, exciting immersion into the blogosphere for AGU. Efforts began with the 2009 Fall Meeting blog, run by AGU staff with the invaluable help of science writing students at University of California, Santa Cruz and New York's Columbia University. This successful experience inspired AGU outreach staff to make a permanent meetings blog, which regularly covers the science presented at AGU meetings.

    LXCat is an open-access website (www.lxcat.net) for exchanging data related to ion and electron transport and scattering cross sections in cold, neutral gases. At present 30 people from 12 countries have contributed to the LXCat project. This presentation will focus on the status of the data available for electrons on LXCat. These data are primarily in the form of ``complete'' sets of cross sections, compiled or calculated by different contributors, covering a range of energies from thermal up to about 1 keV. The cross section data can be used directly in Monte Carlo simulations and can also be used as input to Boltzmann equation solvers. Solution of the homogeneous, steady-state Boltzmann equation yields electron energy distribution functions (edf) as a function of reduced electric field strength, E/N, integrals over which yield electron transport and rate coefficients. The transport and rate coefficient data are required input for fluid models of low temperature plasmas. Evaluation of the cross section data sets available on LXCat is a key issue. To this end, the LXCat team has been making systematic intercomparisons of cross section data and comparisons of calculated and measured transport and rate coefficients. Our evaluations have been reported previously for noble gases and for common atmospheric gases. The LXCat team is now evaluating data for more complex molecules.

    Full Text Available Abstract Background Translating the extraordinary scientific and technological advances occurring in medical research laboratories into care for patients in communities throughout the country has been a major challenge. One contributing factor has been the relative absence of community practitioners from the US biomedical research enterprise. Identifying and addressing the barriers that prevent their participation in research should help bridge the gap between basic research and practice to improve quality of care for all Americans. Methods We interviewed over 200 clinicians and other healthcare stakeholders from 2004 through 2005 to develop a conceptual framework and set of strategies for engaging a stable cadre of community clinicians in a clinical research program. Results Lack of engagement of community practitioners, lack of necessary infrastructure, and the current misalignment of financial incentives and research participation emerged as the three primary barriers to community clinician research participation. Although every effort was made to learn key motivators for engagement in clinical research from interviewees, we did not observe their behavior and self-report by clinicians does not always track with their behavior. Conclusions A paradigm shift involving acknowledgement of the value of clinicians in the context of community research, establishment of a stable infrastructure to support a cohort of clinicians across time and research studies, and realignment of incentives to encourage participation in clinical research is required.

    A public participatory geographical information systems (PPGIS) demographic, environmental, socioeconomic, health status portal was developed for the Stambaugh-Elwood (SE) community in Columbus, OH. We hypothesized that soil at SE residences would have metal concentrations above natural background levels. Three aims were developed that allowed testing of this hypothesis. Aim 1 focused on establishing partnerships between academia, state agencies and communities to assist in the development of a community voice. Aim 2 was to design and conduct soil sampling for residents of the SE community. Aim 3 was to utilize our interactive, customized portal as a risk communication tool by allowing residents to educate themselves as to the potential risks from industrial sources in close proximity to their community. Multiple comparisons of means were used to determine differences in soil element concentration by sampling location at p < 0.05. The results demonstrated that eight metals (As, Cd, Cu, Pb, Mo, Se, Tl, Zn) occurred at statistically-significantly greater levels than natural background levels, but most were below risk-based residential soil screening levels. Results were conveyed to residents via an educational, risk-communication informational card. This study demonstrates that community-led coalitions in collaboration with academic teams and state agencies can effectively address environmental concerns. PMID:26703664

    Acklie, Deanna S.

    Women in the United States are underrepresented in science related careers. The Wonderwise curriculum was designed to encourage young women to become more involved in science and science careers. The Wonderwise kits have won numerous awards for quality science curriculum for formal educational environments. In 2000 the kits were adapted and new kits were developed to meet the needs of a nonformal Teaming environment (i.e., 4-H). The kits contain a video field trip with a featured female scientist demonstrating her work, an activity guidebook with five activities based on this scientist's work, and a CD-Rom serving as an additional resource. This study contributes to our understanding of a group of 4H youth who used the Wonderwise curriculum. It describes their view on science, their perspective about people who do science, the importance of role models within their lives, and their career visions. This study was a multi-method case study design. The subjects were youth ages 9--11 involved in 4H events in a three state area. Events such as overnight camps, day camps, special events and after school programs featuring the Wonderwise curriculum were used as sites for this study. The subjects studied in the Wonderwise 4-H project were primarily female youth who had some interest in science. Nearly half were Caucasian; the remainder were Hispanic, African American and Native American. The 25 youth involved in this study took part in a semi-structure interview process including four research methodologies: open-ended questions, drawing or writing a story about the featured scientist, a card sort activity and a relationship map drawn by the youth. Youths' prior experiences in formal, informal and nonformal settings impacted how they made sense of and incorporated Wonderwise experiences in their frame of reference. Through the experiential learning process youth experienced science activities and connected to individuals with science backgrounds, particularly those

    Social scientific approach has become an important approach in e-Health studies over the past decade. However, there has been little systematical examination of what aspects of e-Health social scientists have studied and how relevant and informative knowledge has been produced and diffused by this line of inquiry. This study performed a systematic review of the body of e-Health literature in mainstream social science journals over the past decade by testing the applicability of a 5A categorization (i.e., access, availability, appropriateness, acceptability, and applicability), proposed by the U.S. Department of Health and Human Services, as a framework for understanding social scientific research in e-Health. This study used a quantitative, bottom-up approach to review the e-Health literature in social sciences published from 2000 to 2009. A total of 3005 e-Health studies identified from two social sciences databases (i.e., Social Sciences Citation Index and Arts & Humanities Citation Index) were analyzed with text topic modeling and structural analysis of co-word network, co-citation network, and scientific food web. There have been dramatic increases in the scale of e-Health studies in social sciences over the past decade in terms of the numbers of publications, journal outlets and participating disciplines. The results empirically confirm the presence of the 5A clusters in e-Health research, with the cluster of applicability as the dominant research area and the cluster of availability as the major knowledge producer for other clusters. The network analysis also reveals that the five distinctive clusters share much more in common in research concerns than what e-Health scholars appear to recognize. It is time to explicate and, more importantly, tap into the shared concerns cutting across the seemingly divided scholarly communities. In particular, more synergy exercises are needed to promote adherence of the field. Copyright © 2014 Elsevier Ireland Ltd. All

    The 13th International Workshop on Plasma-Facing Materials and Components (PFMC-13) jointly organized with the 1st International Conference on Fusion Energy Materials Science (FEMaS-1) was held in Rosenheim (Germany) on 9-13 May 2011. PFMC-13 is a successor of the International Workshop on Carbon Materials for Fusion Applications series. Between 1985 and 2003 ten 'Carbon Workshops' were organized in Jülich, Stockholm and Hohenkammer. Then it was time for a change and redefinition of the scope of the symposium to reflect the new requirements of ITER and the ongoing evolution in the field. Under the new name (PFMC-11), the workshop was first organized in 2006 in Greifswald, Germany and PFMC-12 took place in Jülich in 2009. Initially starting in 1985 with about 40 participants as a 1.5 day workshop, the event has continuously grown to about 220 participants at PFMC-12. Due to the joint organization with FEMaS-1, PFMC-13 set a new record with more than 280 participants. The European project Fusion Energy Materials Science, FEMaS, coordinated by the Max-Planck-Institut für Plasmaphysik (IPP), organizes and stimulates cooperative research activities which involve large-scale research facilities as well as other top-level materials characterization laboratories. Five different fields are addressed: benchmarking experiments for radiation damage modelling, the application of micro-mechanical characterization methods, synchrotron and neutron radiation-based techniques and advanced nanoscopic analysis based on transmission electron microscopy. All these fields need to be exploited further by the fusion materials community for timely materials solutions for a DEMO reactor. In order to integrate these materials research fields, FEMaS acted as a co-organizer for the 2011 workshop and successfully introduced a number of participants from research labs and universities into the PFMC community. Plasma-facing materials experience particularly hostile conditions as they are

  12. Robotics as science (re)form: Exploring power, learning and gender(ed) identity formation in a "community of practice"

    Hurner, Sheryl Marie

    "Robotics as Science (re)Form" utilizes qualitative research methods to examine the career trajectories and gender identity formation of female youth participating as members of an all-girl, academic team within the male-dominated environment of the FIRST Robotics competition. Following the constant comparative approach (Glaser & Strauss, 1967), my project relies upon triangulating ethnographic data drawn from extensive field notes, semi-structured interviews, and digital and video imagery compiled over two years of participant observation. Drawing upon the sociolinguistic "community of practice" (CoP) framework (Eckert & McConnell-Ginet, 1992; Lave & Wenger, 1991; Wenger, 1998), this study maps the range of gendered "identities" available to girls involved in non-traditional academic and occupational pursuits within a local context, and reveals the nature, structure and impact of power operating within this CoP, a significantly underdeveloped construct within the language and gender literature. These research findings (1) contribute to refining theories of situated or problem based learning with a focus on female youth (Lave & Wenger, 1991; Wenger, 1998); (2) reveal affordances and barriers within the local program design that enable (and preclude) women and minority youth entering the engineering pipeline; and (3) enrich our understanding of intragroup language and gendered "practices" to counter largely essentializing generalizations based upon quantitative analysis. Keywords: Robotics, gender, identity formation, science, STEM, communities of practice

    In response to continuing health disparities between rural and urban population, Patan Academy of Health Sciences (PAHS) was established in 2008. It aimed to produce physicians who would be able and willing to serve in the rural areas. In order to empower them with understanding and tools to address health issues of rural population, an innovative curriculum was developed. This paper aims to describe the community based learning and education (CBLE) system within the overall framework of PAHS undergraduate medical curriculum. A Medical School Steering Committee (MSSC) comprising of a group of committed medical educators led the curriculum development process. The committee reviewed different medical curricula, relevant literatures, and held a series of consultative meetings with the stakeholders and experts within and outside Nepal. This process resulted in defining the desirable attributes, terminal competencies of the graduates, and then the actual development of the entire curriculum including CBLE. Given the critical importance of population health, 25% of the curricular weightage was allocated to the Community Health Sciences (CHS). CBLE system was developed as the primary means of delivering CHS curriculum. The details of CBLE system was finalized for implementation with the first cohort of medical students commencing their studies from June 2010. The CBLE, a key educational strategy of PAHS curriculum, is envisaged to improve retention and performance of PAHS graduates and, thereby, health status of rural population. However, whether or not that goal will be achieved needs to be verified after the graduates join the health system.

  14. Recruitment Campaigns as a Tool for Social and Cultural Reproduction of Scientific Communities: A case study on how scientists invite young people to science

    Andrée, Maria; Hansson, Lena

    2014-08-01

    Young people's interest in pursuing science and science-intense educations has been expressed as a concern in relation to societal, economic and democratic development by various stakeholders (governments, industry and university). From the perspective of the scientific communities, the issues at stake do not necessarily correspond to the overall societal aims. Rather, initiatives to recruit young people to science are also ways for the scientific community to engage in the social and cultural reproduction of itself. For a community to survive and produce a future, it needs to secure regeneration of itself in succeeding generations. The aim of this study is to, from a perspective of social and cultural production/reproduction, shed light on an initiative from the scientific community to recruit young people to science education. This is a case study of one recruitment campaign called the Chemistry Advent calendar. The calendar consists of 25 webcasted films, produced and published by the science/technology faculty at a university. The analysed data consist of the films and additional published material relating to the campaign such as working reports and articles published about the campaign. The analysis focussed on what messages are communicated to potential newcomers. The messages were categorised by means of a framework of subjective values. The results are discussed both from a perspective of how the messages mirror traditions and habits of the scientific community, and in relation to research on students' educational choices.

    The Partnership Network Knowledge Base (PNKB) is being developed to provide connectivity and deliver content for the research information needs of NASA's Applied Science Program and related scientific communities of practice. Data has been collected which will permit users to identify and analyze the current network of interactions between organizations within the community of practice, harvest research results fixed to those interactions, and identify potential collaborative opportunities to further research streams. The PNKB is being developed in parallel with the Research Projects Knowledge Base (RPKB) and will be deployed in a manner that is fully compatible and interoperable with the NASA enterprise architecture (EA). Information needs have been assessed through a survey of potential users, evaluations of existing NASA resource users, and collaboration between Stennis Space Center and The Mississippi Research Consortium (MRC). The PNKB will assemble information on funded research institutions and categorize the research emphasis of each as it relates to NASA's six major science focus areas and 12 national applications. The PNKB will include information about organizations that conduct NASA Earth Science research such as, principal investigators' affiliation, contact information, relationship-type with NASA and other NASA partners, funding arrangements, and formal agreements like memoranda-of-understanding. To further the utility of the PNKB, relational links have been integrated into the RPKB - which will contain data about projects awarded from NASA research solicitations, project investigator information, research publications, NASA data products employed, and model or decision support tools used or developed as well as new data product information. The combined PNKB and RPKB will be developed in a multi-tier architecture that will include a SQL Server relational database backend, middleware, and front end client interfaces for data entry.

  16. The negotiation of meaning and exercise of power in professional learning communities: An investigation of middle school science teachers

    Mclaughlin, Cheryl Althea

    A professional learning community (PLC) typically consists of practitioners who systematically examine and problematize their practice with the intention of development and improvement. The collaborative practices inherent in PLCs mirror the way scientists work together to develop new theories, and are particularly valuable for science teachers who could draw from these experiences to improve the quality of student learning. Gaps in the science education literature support the need for research to determine how interactions within PLCs support science teacher development. Additionally, issues of power that may constrain or encourage meaningful interactions are largely overlooked in PLC studies. This qualitative study examines, from a Foucauldian perspective, interactions within a PLC comprising middle school science teachers preparing to implement reform curriculum. Specifically, the study analyzes interactions within the PLC to determine opportunities created for professional learning and development. Audiotaped transcripts of teacher interactions were analyzed using discourse analysis building tasks designed to identify opportunities for learning and to examine the exercise of power within the PLCs. The discourse analytical tools integrated theories of Gee (2011) and Foucault (1972), and were used to deconstruct and interrogate the data. The events were subsequently reconstructed through the lens of social constructivism and Foucault theories on power. The findings identified several processes emerging from the interactions that contributed to the negotiation of an understanding of the reform curriculum. These include reflection on practice, reorganization of cognitive structures, reinvention of practice, and refinement of instructional strategies. The findings also indicated that the exercise of power by entities both external to, and within the PLCs influenced the process of meaning negotiation among the science teachers. The consensus achieved by the teachers

    The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) is the home of processing, archiving, and distribution services for NASA sounders: the present Aqua AIRS mission and the succeeding SNPP CrIS mission. The AIRS mission is entering its 15th year of global observations of the atmospheric state, including temperature and humidity profiles, outgoing longwave radiation, cloud properties, and trace gases. The GES DISC, in collaboration with the AIRS Project, released product from the version 6 algorithm in early 2013. Giovanni, a Web-based application developed by the GES DISC, provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Most important variables from version 6 AIRS product are available in Giovanni. We are developing a climatology product using 14-year AIRS retrievals. The study can be a good start for the long term climatology from NASA sounders: the AIRS and the succeeding CrIS. This presentation will show the impacts to the climatology product from different aggregation methods. The climatology can serve climate science and application communities in data visualization and analysis, which will be demonstrated using a variety of functions in version 4 Giovanni. The highlights of these functions include user-defined monthly and seasonal climatology, inter annual seasonal time series, anomaly analysis.

    Full Text Available The purpose of this study was to explore the role that a collaborative teaching approach, referred to as a community of practice (CoP, had on a team of four second grade teachers’ implementation of a science-based interdisciplinary curriculum. Data was collected in the form of extensive observation notes gathered over 10-weeks of twice weekly team meetings and two 45 minute interviews with each participant. From the field notes developed twovignettes for the purpose of illustrating the members CoP in action. Combining my analysis of the vignettes and the interviews resulted in three emergent themes: 1 benefits, 2 contributions, and 3 their commitment to professional development. From this study Ilearned that establishing a CoP was viewed as a necessary component of the team’s implementation of their science-based interdisciplinary curriculum. Implications for encouraging preservice and inservice elementary teachers to develop CoPs to support science teaching, specifically interdisciplinary teaching, are discussed.

    Colgan, James

    2016-05-01

    We report on efforts to model the low-temperature plasmas generated using laser-induced breakdown spectroscopy (LIBS). LIBS is a minimally invasive technique that can quickly and efficiently determine the elemental composition of a target and is employed in an extremely wide range of applications due to its ease of use and fast turnaround. In particular, LIBS is the diagnostic tool used by the ChemCam instrument on the Mars Science Laboratory rover Curiosity. In this talk, we report on the use of the Los Alamos plasma modeling code ATOMIC to simulate LIBS plasmas, which are typically at temperatures of order 1 eV and electron densities of order 10 16 - 17 cm-3. At such conditions, these plasmas are usually in local-thermodynamic equilibrium (LTE) and normally contain neutral and singly ionized species only, which then requires that modeling must use accurate atomic structure data for the element under investigation. Since LIBS devices are often employed in a very wide range of applications, it is therefore desirable to have accurate data for most of the elements in the periodic table, ideally including actinides. Here, we discuss some recent applications of our modeling using ATOMIC that have explored the plasma physics aspects of LIBS generated plasmas, and in particular discuss the modeling of a plasma formed from a basalt sample used as a ChemCam standard1. We also highlight some of the more general atomic physics challenges that are encountered when attempting to model low-temperature plasmas. The Los Alamos National Laboratory is operated by Los Alamos National Security, LLC for the National Nuclear Security Administration of the U.S. Department of Energy under Contract No. DE-AC5206NA25396.

    This document summarizes the results of a community-based discussion of the potential science impact of the Mayall+BigBOSS highly multiplexed multi-object spectroscopic capability. The KPNO Mayall 4m telescope equipped with the DOE- and internationally-funded BigBOSS spectrograph offers one of the most cost-efficient ways of accomplishing many of the pressing scientific goals identified for this decade by the "New Worlds, New Horizons" report. The BigBOSS Key Project will place unprecedented constraints on cosmological parameters related to the expansion history of the universe. With the addition of an open (publicly funded) community access component, the scientific impact of BigBOSS can be extended to many important astrophysical questions related to the origin and evolution of galaxies, stars, and the IGM. Massive spectroscopy is the critical missing ingredient in numerous ongoing and planned ground- and space-based surveys, and BigBOSS is unique in its ability to provide this to the US community.

  18. Producing "science/fictions" about the rural and urban poor: Community-based learning at a medical college in South India

    Science.gov (United States)

    Arur, Aditi Ashok

    This dissertation is an ethnographic case study of a community-based teaching program (CBTP) in public health at a medical college in South India that explored how the CBTP produced particular ways of seeing and understanding rural and urban poor communities. Drawing from critical, feminist, and postcolonial scholars, I suggest that the knowledge produced in the CBTP can be understood as "science/fictions", that is, as cultural texts shaped by transnational development discourses as well as medical teachers' and students' sociospatial imaginations of the rural and urban poor. I explored how these science/fictions mediated medical students' performative actions and interactions with a rural and an urban poor community in the context of the CBTP. At the same time, I also examined how knowledge produced in students' encounters with these communities disrupted their naturalized understandings about these communities, and how it was taken up to renarrativize science/fictions anew. Data collection and analyses procedures were informed by critical ethnographic and critical discourse analysis approaches. Data sources includes field notes constructed from observations of the CBTP, interviews with medical teachers and students, and curricular texts including the standardized national textbook of public health. The findings of this study illustrate how the CBTP staged the government and technology as central actors in the production of healthy bodies, communities, and environments, and implicitly positioned medical teachers and students as productive citizens of a modern nation while rural and urban poor communities were characterized sometimes as empowered, and at other times as not-yet-modern and in need of reform. However, the community also constituted an alternate pedagogical site of engagement in that students' encounters with community members disrupted students' assumptions about these communities to an extent. Nevertheless, institutionalized practices of assessment

  19. High Energy Density Plasmas (HEDP) for studies of basic nuclear science relevant to Stellar and Big Bang Nucleosynthesis

    Frenje, Johan

    2014-06-01

    Thermonuclear reaction rates and nuclear processes have been explored traditionally by means of conventional accelerator experiments, which are difficult to execute at conditions relevant to stellar nucleosynthesis. Thus, nuclear reactions at stellar energies are often studied through extrapolations from higher-energy data or in low-background underground experiments. Even when measurements are possible using accelerators at relevant energies, thermonuclear reaction rates in stars are inherently different from those in accelerator experiments. The fusing nuclei are surrounded by bound electrons in accelerator experiments, whereas electrons occupy mainly continuum states in a stellar environment. Nuclear astrophysics research will therefore benefit from an enlarged toolkit for studies of nuclear reactions. In this presentation, we report on the first use of High Energy Density Plasmas for studies of nuclear reactions relevant to basic nuclear science, stellar and Big Bang nucleosynthesis. These experiments were carried out at the OMEGA laser facility at University of Rochester and the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, in which spherical capsules were irradiated with powerful lasers to compress and heat the fuel to high enough temperatures and densities for nuclear reactions to occur. Four experiments will be highlighted in this presentation. In the first experiment, the differential cross section for the elastic neutron-triton (n-T) scattering at 14.1 MeV was measured with significantly higher accuracy than achieved in accelerator experiments. In the second experiment, the T(t,2n)4He reaction, a mirror reaction to the 3He(3He,2p)4He reaction that plays an important role in the proton-proton chain that transforms hydrogen into ordinary 4He in stars like our Sun, was studied at energies in the range 15-40 keV. In the third experiment, the 3He+3He solar fusion reaction was studied directly, and in the fourth experiment, we

    Brownsville, Texas in the Rio Grande Valley is the site of an annual space science outreach event that illustrates successful methods of communicating science across cultural and economical boundaries. The Lower Rio Grande valley is predominantly rural, Spanish speaking with large portions of the population at or below the poverty line. Many of the Latino students drop out of school before receiving a high school diploma. For the past four years the University of Texas at Brownsville (UTB) has brought a group of educators, high school and undergraduate students to Houston for training at Johnson Space Center and the Houston Museum of Natural Science. The group subsequently organizes a one day event for 5th-8th grade students, teachers and administrators that is focused on a space science theme. In 2006 over 500 participants learned about NASA's return to the Moon. The attendees listened to a talk by a NASA scientist, viewed exhibits of lunar materials and participated in 20 different hands-on activities. Examples of the activities were the effects of the Sun's solar winds on regolith formation, lunar craters, potential water resources and future exploration. The event is a success because it is locally supported and organized by UTB and its students. UTB has taken "ownership" of the yearly activity. Outside support is limited to scientific data and information, supplying a guest speaker and materials support. Materials support can include NASA displays, telescopes, a portable planetarium and selected planetarium shows. Communication barriers between English speaking and Spanish speaking are eliminated as over ninety percent of the local leaders are bilingual. Additionally the portable planetarium has Spanish language programs. This is an example of an activity that crosses across cultural boundaries and can be exported to other regions of the western hemisphere.

    Virtual reality and immersive worlds refer to artificial computer-generated environments, with which users act and interact as in a known environment by the use of figurative virtual individuals (avatars). Virtual environments will be the technology of the early twenty-first century that will most dramatically change the way we live, particularly in the areas of training and education, product development and entertainment (Schmorrow, 2009). The usefulness of immersive worlds has been proved in different fields. They reduce geographic and social barriers between different stakeholders and create virtual social spaces which can positively impact learning and discussion outcomes (Lorenzo et al. 2012). In this work we present a series of interactive meetings in a virtual building to celebrate the International Year of Soil to promote the importance of soil functions and its conservation. In a virtual room, the avatars of different senior researchers will meet young scientist avatars to talk about: 1) what remains to be done in Soil Sciences; 2) which are their main current limitations and difficulties and 3) which are the future hot research lines. The interactive participation does not require physically attend to the EGU Assembly 2015. In addition, this virtual building inspired in Soil Sciences can be completed with different teaching resources from different locations around the world and it will be used to improve the learning of Soil Sciences in a multicultural context.

    Cat predation of birds in residential landscapes is ephemeral, unpredictable, and spatially dispersed, and thus requires many person-hours to observe. We sought to identify whether specific behaviors, traits, or feeding ecologies of birds contribute to their probability of cat-caused mortality around residences across temperate North America. In addressing this question, we evaluated citizen science data with respect to peer-reviewed species accounts (Birds of North America, BNA). Using information on cat predation from the BNA, we found that species that glean their prey from the ground or breed in nest boxes were three times more likely to be depredated by cats, while birds that hawk were over two times less likely to become cat prey than would be predicted by random chance. Data from citizen science sources also showed that birds using nest boxes had increased susceptibility to cat predation, as did those that use feeders and that glean from foliage. We caution that observations of predation by citizen science volunteers may be biased towards detection at feeders. Future research should focus on developing volunteer survey techniques for improving estimates of bird mortality rates and sources.

    2014-03-01

    In this paper the insights and results are presented of a long term and ongoing improvement effort within the Netherlands Forensic Institute (NFI) to establish a valuable innovation programme. From the overall perspective of the role and use of forensic science in the criminal justice system, the concepts of Forensic Information Value Added (FIVA) and Forensic Information Value Efficiency (FIVE) are introduced. From these concepts the key factors determining the added value of forensic investigations are discussed; Evidential Value, Relevance, Quality, Speed and Cost. By unravelling the added value of forensic science and combining this with the future needs and scientific and technological developments, six forensic grand challenges are introduced: i) Molecular Photo-fitting; ii) chemical imaging, profiling and age estimation of finger marks; iii) Advancing Forensic Medicine; iv) Objective Forensic Evaluation; v) the Digital Forensic Service Centre and vi) Real time In-Situ Chemical Identification. Finally, models for forensic innovation are presented that could lead to major international breakthroughs on all these six themes within a five year time span. This could cause a step change in the added value of forensic science and would make forensic investigative methods even more valuable than they already are today.

While most of the research on educational objectives has focused on the cognitive domain, the research that has been conducted on the affective domain, which speaks to emotions, attitudes, and values, has identified a number of positive outcomes. One approach to enhancing the affective domain is that of interdisciplinary education. Science education research in the realm of interdisciplinary education and affective outcomes is limited; especially research conducted on community college students of human anatomy. This project investigated the relationship between an interdisciplinary teaching strategy and the affective domain in science education by utilizing an interdisciplinary lecture in a human anatomy class. Subjects were anatomy students in a California community college who listened to a one-hour lecture describing the cultural, historical and scientific significance of selected pieces of art depicting human dissection in European medieval and Renaissance universities. The focus was on how these renderings represent the state of anatomy education during their respective eras. After listening to the lecture, subjects were administered a 35-question survey that was composed of 14 demographic questions and 21 Likert-style statements that asked respondents to rate the extent to which the intervention influenced their affective domain. Descriptive statistics were then used to determine which component of the affective domain was most influenced, and multiple regression analysis was used to examine the extent to which individual differences along the affective continuum were explained by select demographic measures such as gender, race/ethnicity, education level, and previous exposure to science courses. Results indicate that the interdisciplinary intervention had a positive impact on every component of the affective domain hierarchy

    Collaborations among geoscience-oriented departments at California State University, Long Beach (Geological Sciences, as well as portions of the Geography and Anthropology departments and a new, fast-growing Environmental Sciences and Policy (ES&P) program) are characterized by attention to three important elements: (1) community-based partnerships and research, (2) outreach and continuity within educational pipeline transitions from high school, to community college, to university, and, (3) sharing of resources and expertise. Three specific collaborations, (1) creation of the ES&P, (2) the NSF-funded Geoscience Diversity Enhancement Program (GDEP), and, (3) the Institute for Interdisciplinary Research on Materials, Environment, and Societies (IIRMES), are powerful illustrations of how these collaborations can work to foster geoscience student recruitment and academic development, particularly at urban, highly diverse institutions with limited resources. Through a combination of student surveys, focus groups, and institutional research supported by the GDEP program, we know (e.g., Whitney et al., 2005) that non-Caucasian students often express less affinity for the geosciences as a focus of study than Caucasians. Early exposure to positive field and laboratory experiences, better understanding of geoscience career possibilities, and better advising at high school and college levels are all excellent strategies for heightening student interest and recruitment in the geosciences, yet appear to be lacking for many of the students in the greater Long Beach, California area. GDEP, ES&P, and IIRMES all challenge these lacunae by emphasizing hands-on learning, research on relevant community-based problems, and one-on-one or small group research, advising and mentoring. Our current challenge is to help our high-school and community-college colleagues adopt their own model of these active-learning strategies, thereby priming the pump and patching the pipe(line) for student

    Full Text Available Organochlorine (OC pesticides have been extensively used for pest control in agriculture and against malaria vectors in the region of Soconusco, Chiapas, in southern Mexico. Our study aimed to identify whether the inhabitants of four Soconusco communities at different locations (i.e., altitudes and with different history of use of OC pesticides, have been similarly exposed to residues of these pesticides. In particular, we analyzed the potential relationship between levels of OC pesticides in plasma and the age, gender, and residence of the study population (n = 60. We detected seven pesticides in total (γ-HCH, β-HCH, heptachlor, p,pʹ-DDE, p,p'-DDT, β-endosulfan, endrin aldehyde. Of these, p,pʹ-DDE and β-endosulfan were the most frequently found (in 98% and 38% of the samples, respectively. The low-altitude (<20 m above sea level; masl and mid-altitude (520 masl locations had the highest levels of p,pʹ-DDE, with geometric means of 50.6 µg/L and 44.46 µg/L, respectively. The oldest subjects (>60 years had the highest p,pʹ-DDE level (56.94 ± 57.81 µg/L of all age groups, while men had higher p,pʹ-DDE (34.00 ± 46.76 µg/L than women. Our results demonstrate that residents of the Soconusco region are exposed to p,pʹ-DDE because of high exposure to DDT in the past and current environmental exposure to this DDT-breakdown product.

  12. The Language of Science as a bridge to the Native American Community

    2010-10-01

    In this talk we will present a concept for building on Native American languages and incorporating STEM concepts. Recently, a student from the Navajo Dine community took it upon himself to define 28 "NASA" terms in the Navajo language. These terms included such words as space telescope, weather satellite, space suit, and the planets including Neptune and Uranus. We hope to add to this word list with geology and astronomy (comet-related) terms, just as we will in Rosetta public engagement for English-speakers. The U.S. Rosetta project will host these words on a web-site, and provide translation into both Navajo and English. A clickable map will allow the user to move through all the words, see Native artwork related to the word, and hear audio translation. The initiative will be expanded into other Native communities such as Hawaiian with the objective of drawing Native American students to the marvelous images, and other data, returned from NASA space missions. Native Americans emphasize the need to know themselves and their own culture when teaching their students. One of the most important near-term problems is the preservation of Native American language. In some communities, small numbers of native speakers remain. The retention of language, and need to make it relevant to the technological age, represents a large and urgent challenge. The U.S. Rosetta Project is NASA's contribution to the International Rosetta Mission. Rosetta is expected to provide the keys to the primordial solar system the way the original Rosetta Stone provided a key to ancient language. STEM language elements in Navajo, Hawaiian, and Ojibwe can be found at the U.S. Rosetta website: http://rosetta.jpl.nasa.gov. Work at the Jet Propulsion Laboratory, California Institute of Technology, was supported by NASA. The Rosetta mission is a cooperative project of NASA and the European Space Agency.

    Interest in the role that ecosystems play in reducing the impacts of coastal hazards has grown dramatically. Yet the magnitude and nature of their effects are highly context dependent, making it difficult to know under what conditions coastal habitats, such as saltmarshes, reefs, and forests, are likely to be effective for saving lives and protecting property. We operationalize the concept of natural and nature-based solutions for coastal protection by adopting an ecosystem services framework that propagates the outcome of a management action through ecosystems to societal benefits. We review the literature on the basis of the steps in this framework, considering not only the supply of coastal protection provided by ecosystems but also the demand for protective services from beneficiaries. We recommend further attention to (1) biophysical processes beyond wave attenuation, (2) the combined effects of multiple habitat types (e.g., reefs, vegetation), (3) marginal values and expected damage functions, and, in particular, (4) community dependence on ecosystems for coastal protection and co-benefits. We apply our approach to two case studies to illustrate how estimates of multiple benefits and losses can inform restoration and development decisions. Finally, we discuss frontiers for linking social, ecological, and physical science to advance natural and nature-based solutions to coastal protection. © 2017 New York Academy of Sciences.

    This report presents the findings and recommendations that emerged from a one-day workshop held at Lawrence Berkeley National Laboratory (LBNL) on June 5, 2002, in conjunction with the NERSC User Group (NUG) Meeting. The motivation for this workshop was to solicit direct input from the application science community on the subject of visualization. The workshop speakers and participants included computational scientists from a cross-section of disciplines that use the NERSC facility, as well as visualization researchers from across the country. We asked the workshop contributors how they currently visualize their results, and how they would like to do visualization in the future. We were especially interested in each individual's view of how visualization tools and services could be improved in order to better meet the needs of future computational science projects. The outcome of this workshop is a set of findings and recommendations that are presented in more detail later in this report, and briefly summarized here.

  15. Acceptance of Climate Change by Rural Farming Communities in Delta State, Nigeria: Effect of Science and Government Credibility

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available This study was conducted to examine Delta State rural farming communities’ attitude to climate change in relation to science and government credibility. A preparatory assessment of Delta State rural communities’ understanding of climate change and insights into potential barriers to communication were given by influences on their attitudes. Average of 60.46% of the farmers reported that climate change was occurring and asserted that climate change was the consequence of human activities. Most (91.23% were certain that climate change is adversely affecting their farming businesses. Many (mean=1.40 found climate change information not easily comprehensible. However the farmers have negative view about the credibility of science, but had low levels of confidence in government. They reported that lack of information was a barrier to adaptation to climate change. This suggests that such barrier lies with the Delta State extension service. There is also an indication that government through the public extension service, need to wake up to her responsibilities of sending related information the rural farming communities. The government should consider the local socio-cultural economic and biophysical environment of the farmers the information is meant for.

    2008-01-01

    The Planetary Data System (PDS) information model is a mature but complex model that has been used to capture over 30 years of planetary science data for the PDS archive. As the de-facto information model for the planetary science data archive, it is being adopted by the International Planetary Data Alliance (IPDA) as their archive data standard. However, after seventeen years of evolutionary change the model needs refinement. First a formal specification is needed to explicitly capture the model in a commonly accepted data engineering notation. Second, the core and essential elements of the model need to be identified to help simplify the overall archive process. A team of PDS technical staff members have captured the PDS information model in an ontology modeling tool. Using the resulting knowledge-base, work continues to identify the core elements, identify problems and issues, and then test proposed modifications to the model. The final deliverables of this work will include specifications for the next generation PDS information model and the initial set of IPDA archive data standards. Having the information model captured in an ontology modeling tool also makes the model suitable for use by Semantic Web applications.

  18. How Can the Science Community Support Reality Based Policies to Reducing the Escalating Toll of Natural Hazards?

    Thomas, E. A.

    2012-12-01

    Worldwide, the toll of disaster damage caused by foreseeable natural hazards is growing, despite the fact that science is increasingly able to quantify the risk and foresee the likely location of natural events (NCDC 2012; NHC 2010). Those events can cause disastrous consequences if human built infrastructure is not properly designed for both the current state and future events (IBHS, 2012). Our existing approaches are not working at reducing the mounting toll of disasters which follow foreseeable natural events. Rather, even if the climate were not changing, current land use decisions coupled with development, engineering, design, and construction practices are significantly contributing to further increasing an unsustainable toll from disasters (Pielke, Gratz et al. 2007). Safe and proper construction practices developed to reduce flood losses (e.g. Design for Flooding, Watson, Adams et al., 2010) are all too often thought of as a zero sum situation where the community wins and the developer loses. In reality, the United States and the rest of the world often can find win-win solutions based on sound economics, law, ethics, and environmental sustainability that will benefit communities, developers, and natural hazard risk mitigation practitioners. While such solutions are being implemented in a fragmentary manner throughout the United States, communities implementing these solutions are increasingly working together in peer networks, such as the Natural Hazard Mitigation Association (NHMA)'s Resilient Neighbors Network. Examples include the Urban Drainage and Flood Control District that covers the metropolitan Denver area and recent work in Tulsa, Oklahoma. This presentation will set forth the scientific, ethical, and legal basis of higher development standards which, when combined with good negotiations techniques, can significantly decrease the terrible misery from wildfires, tornadoes, floods, and other natural disasters. Communities clearly have the legal

    Communities that are the most vulnerable to environmental change and hazards, also tend to be those with the least institutional and financial resilience and capacity to cope with consequent impacts. Relevant knowledge generation is a key requisite for empowering these communities and developing adaptation strategies. Technological innovations in data collection, availability, processing, and exchange, are creating new opportunities for knowledge co-generation that may benefit vulnerable communities and bridge traditional knowledge divides. The use of open, web-based technologies and ICT solutions such as mobile phone apps is particularly promising in this regard, because they allow for participation of communities bypassed by traditional mechanisms. Here, we report on efforts to implement such technologies in a citizen science context. We focus on the active engagement of multiple actors (international and local scientists, government officials, NGOs, community associations, and individuals) in the entire process of the research. This ranges from problem framing, to identifying local monitoring needs, to determining the mode of exchange and forms of knowledge relevant for improving resilience related to water dependency. We present 4 case studies in arid, remote mountain regions of Nepal, the Kyrgyz Republic, Peru, and Ethiopia. In these regions, livelihoods depend on the water and soil systems undergoing accelerated degradation from extreme climates, poor agricultural management practices, and changing environmental conditions. However, information on the interlinkages of these processes with people's livelihoods is typically poor and there lies the opportunity for identifying novel forms of joint-creation and sharing of knowledge.

    Background It is not clear whether elevated uric acid is a risk factor for the onset of impaired fasting glucose after stratifying by baseline fasting plasma glucose levels. We conducted a community-based retrospective longitudinal cohort study to clarify the relationship between uric acid levels and the onset of impaired fasting glucose, according to baseline fasting plasma glucose levels. Methods We enrolled 6,403 persons (3,194 men and 3,209 women), each of whom was 18–80 years old and had >2 annual check-ups during 2003–2010. After excluding persons who had fasting plasma glucose levels ≥6.11 mM and/or were currently taking anti-diabetic agents, the remaining 5,924 subjects were classified into quartiles according to baseline fasting plasma glucose levels. The onset of impaired fasting glucose was defined as fasting plasma glucose ≥6.11 mM during the observation period. Results In the quartile groups, 0.9%, 2.1%, 3.4%, and 20.2% of the men developed impaired fasting glucose, respectively, and 0.1%, 0.3%, 0.5%, and 5.6% of the women developed impaired fasting glucose, respectively (P trend fasting glucose in men with highest-quartile fasting plasma glucose levels (adjusted hazard ratio, 1.003; 95% confidence interval, 1.0001–1.005, P = 0.041). Conclusions Among men with high fasting plasma glucose, hyperuricemia may be independently associated with an elevated risk of developing impaired fasting glucose. PMID:25237894

    In this study, a new physics education programme is specifically developed for a famous theme park in Hong Kong to provide community-based science learning to her visitors, involving her three newly constructed rides. We make innovative use of digital technologies in this programme and incorporate a rigorous evaluation of the learning effectiveness of the programme. A total of around 200 students from nine local secondary schools participated in both the physics programme and its subsequent evaluation which consists of a combination of research and assessment tools, including pre- and post-multiple-choice tests, a questionnaire survey and an interview as specifically developed for this programme, or adopted from some well-accepted research instruments. Based on the evaluation of students' academic performance, there are two educationally significant findings on enhancing the students' physics learning: (a) traditionally large gender differences in physics performance and interest of learning are mostly eliminated; and (b) a less-exciting ride called the aviator (instead of the most exciting roller-coaster ride) can induce the largest learning effect (or gain in academic performance) amongst teenagers. Besides, findings from the questionnaire survey and interviews of participants are reported to reveal their views, perceptions, positive and negative comments or feedback on this programme which could provide valuable insights for future development of other similar community-based programmes.

    Korea has developed advanced nuclear technologies, including those for future nuclear energy systems and the safe management of spent nuclear fuel, and is about to make a decision as to whether to make a massive investment in the development R and D for commercialization of them. There is no area large enough to accommodate all the development R and D-related facilities together at Korea Atomic Energy Research Institute (KAERI) to perform the development R and Ds. KAERI seeks solutions to the space problem, which includes the construction of a nuclear energy science complex (NESC). Gyeongju is one of the potential sites. This study estimated the ripple effects on the regional community if the NESC is to be formed in Gyeongju using inter-regional input-output analysis. The estimation shows that the ripple effects to the regional community of the formation of the NESC in Gyeongju would be 1,086,633 billion Korean Won (KRW) for regional production inducement, 455,299 billion KRW for value-added inducement, and 9,592 persons for employment inducement.

    The conception of Global Learning Communities (GLCs) was researched to discover potential benefits of the use of online technologies that facilitated communication and scientific data sharing outside of the normal classroom setting. 1,419 students in 635 student groups began the instructional unit. Students represented the classrooms of 33 teachers from the USA, 6 from Thailand, 7 from Australia, and 4 from Germany. Data from an international environmental education project were analyzed to describe grades 7-9 student scientific writing in domestic US versus international-US classroom online partnerships. The development of an argument analytic and a research model of exploratory data analysis followed by statistical testing were used to discover and highlight different ways students used evidence to support their scientific claims about temperature variation at school sites and deep-sea hydrothermal vents. Findings show modest gains in the use of some evidentiary discourse components by US students in international online class partnerships compared to their US counterparts in domestic US partnerships. The analytic, research model, and online collaborative learning tools may be used in other large-scale studies and learning communities. Results provide insights about the benefits of using online technologies and promote the establishment of GLCs.

    Having the ability to scan the entire country for potential "hotspots" with increased risk of developing chronic diseases due to various environmental, demographic, and genetic susceptibility factors may inform risk management decisions and enable better environmental public health policies. Develop an approach for community-level risk screening focused on identifying potential genetic susceptibility hotpots. Our approach combines analyses of phenotype-genotype data, genetic prevalence of single nucleotide polymorphisms, and census/geographic information to estimate census tract-level population attributable risks among various ethnicities and total population for the state of California. We estimate that the rs13266634 single nucleotide polymorphism, a type 2 diabetes susceptibility genotype, has a genetic prevalence of 56.3%, 47.4% and 37.0% in Mexican Mestizo, Caucasian, and Asian populations. Looking at the top quintile for total population attributable risk, 16 California counties have greater than 25% of their population living in hotspots of genetic susceptibility for developing type 2 diabetes due to this single genotypic susceptibility factor. This study identified counties in California where large portions of the population may bear additional type 2 diabetes risk due to increased genetic prevalence of a susceptibility genotype. This type of screening can easily be extended to include information on environmental contaminants of interest and other related diseases, and potentially enables the rapid identification of potential environmental justice communities. Other potential uses of this approach include problem formulation in support of risk assessments, land use planning, and prioritization of site cleanup and remediation actions.

    The extent of metal contamination in Sydney residential garden soils was evaluated using data collected during a three-year Macquarie University community science program called VegeSafe. Despite knowledge of industrial and urban contamination amongst scientists, the general public remains under-informed about the potential risks of exposure from legacy contaminants in their home garden environment. The community was offered free soil metal screening, allowing access to soil samples for research purposes. Participants followed specific soil sampling instructions and posted samples to the University for analysis with a field portable X-ray Fluorescence (pXRF) spectrometer. Over the three-year study period, >5200 soil samples, primarily from vegetable gardens, were collected from >1200 Australian homes. As anticipated, the primary soil metal of concern was lead; mean concentrations were 413 mg/kg (front yard), 707 mg/kg (drip line), 226 mg/kg (back yard) and 301 mg/kg (vegetable garden). The Australian soil lead guideline of 300 mg/kg for residential gardens was exceeded at 40% of Sydney homes, while concentrations >1000 mg/kg were identified at 15% of homes. The incidence of highest soil lead contamination was greatest in the inner city area with concentrations declining towards background values of 20-30 mg/kg at 30-40 km distance from the city. Community engagement with VegeSafe participants has resulted in useful outcomes: dissemination of knowledge related to contamination legacies and health risks; owners building raised beds containing uncontaminated soil and in numerous cases, owners replacing all of their contaminated soil.

    Many Native American communities recognize that the retention of their language, and the need to make the language relevant to the technological age we live in, represents one of their largest and most urgent challenges. Almost 70 percent of Navajos speak their tribal language in the home, and 25 per cent do not know English very well. In contrast, only 30 percent of Native Americans as a whole speak their own tribal language in the home. For the Cherokee and the Chippewa, less than 10 percent speak the native language in the home. And for the Navajo, the number of first graders who solely speak English is almost four times higher than it was in 1970. The U.S. Rosetta Project is the NASA contribution to the International Rosetta Mission. The Rosetta stone is the inspiration for the mission’s name. As outlined by the European Space Agency, Rosetta is expected to provide the keys to the primordial solar system the way the original Rosetta Stone provided a key to ancient language. The concept of ancient language as a key provides a theme for this NASA project’s outreach to Native American communities anxious for ways to enhance and improve the numbers of native speakers. In this talk we will present a concept for building on native language as it relates to STEM concepts. In 2009, a student from the Dine Nation interpreted 28 NASA terms for his senior project at Chinle High School in Chinle, AZ. These terms included such words as space telescope, weather satellite, space suit, and the planets including Neptune and Uranus. This work represents a foundation for continued work between NASA and the Navajo Nation. Following approval by the tribal elders, the U.S. Rosetta project would host the newly translated Navajo words on a web-site, and provide translation into both Navajo and English. A clickable map would allow the user to move through all the words, see Native artwork related to the word, and hear audio translation. Extension to very remote teachers in the

    @@ It is my very great pleasure to announce the launch of Protein & Cell. Understanding the cell, the basic unit of life, is a complicated process but is the source for all the key answers pertaining to the life sciences. A sophisticated view of the nature and essence of life requires systematic studies of the whole cell and the cellular components, ranging from small molecules, nucleic acids and carbohydrates to proteins and macromolecular complexes. Starting from the universal genetic cede,as simple as A, C, T and G, twenty standard amino acids are translated and thousands of proteins are assembled. Proteins function in concert with molecules both inside and outside cells. A single cell can represent the entirety of life in the case of bacteria, while differentiated cells form more complicated tissues and organisms. As implied by the title,Protein & Cell intends to promote greater understanding of the cell, the elementary unit of life, via structural and functional studies of its components.

    The Jet Propulsion Laboratory has traditionally housed one of the world's largest databases of volcanic satellite imagery, the ASTER Volcano Archive (10Tb), making these data accessible online for public and scientific use. However, a series of changes in how satellite imagery is housed by the Earth Observing System (EOS) Data Information System has meant that JPL has been unable to systematically maintain its database for the last several years. We have provided a fast, transparent, machine-to-machine client that has updated JPL's database and will keep it current in near real-time. The development of this client has also given us the capability to retrieve any data provided by NASA's Earth Observing System Clearinghouse (ECHO) that covers a volcanic event reported by U.S. Air Force Weather Agency (AFWA). We will also provide a publicly available tool that interfaces with ECHO that can provide functionality not available in any of ECHO's Earth science discovery tools.

    Production operation of large distributed computing infrastructures (DCI) still requires a lot of human intervention to reach acceptable quality of service. This may be achievable for scientific communities with solid IT support, but it remains a show-stopper for others. Some application execution environments are used to hide runtime technical issues from end users. But they mostly aim at fault-tolerance rather than incident resolution, and their operation still requires substantial manpower. A longer-term support activity is thus needed to ensure sustained quality of service for Virtual Organisations (VO). This paper describes how the biomed VO has addressed this challenge by setting up a technical support team. Its organisation, tooling, daily tasks, and procedures are described. Results are shown in terms of resource usage by end users, amount of reported incidents, and developed software tools. Based on our experience, we suggest ways to measure the impact of the technical support, perspectives to decrea...

  12. Can data science inform environmental justice and community risk screening for type 2 diabetes?

    Full Text Available Having the ability to scan the entire country for potential "hotspots" with increased risk of developing chronic diseases due to various environmental, demographic, and genetic susceptibility factors may inform risk management decisions and enable better environmental public health policies.Develop an approach for community-level risk screening focused on identifying potential genetic susceptibility hotpots.Our approach combines analyses of phenotype-genotype data, genetic prevalence of single nucleotide polymorphisms, and census/geographic information to estimate census tract-level population attributable risks among various ethnicities and total population for the state of California.We estimate that the rs13266634 single nucleotide polymorphism, a type 2 diabetes susceptibility genotype, has a genetic prevalence of 56.3%, 47.4% and 37.0% in Mexican Mestizo, Caucasian, and Asian populations. Looking at the top quintile for total population attributable risk, 16 California counties have greater than 25% of their population living in hotspots of genetic susceptibility for developing type 2 diabetes due to this single genotypic susceptibility factor.This study identified counties in California where large portions of the population may bear additional type 2 diabetes risk due to increased genetic prevalence of a susceptibility genotype. This type of screening can easily be extended to include information on environmental contaminants of interest and other related diseases, and potentially enables the rapid identification of potential environmental justice communities. Other potential uses of this approach include problem formulation in support of risk assessments, land use planning, and prioritization of site cleanup and remediation actions.

We claim that educational research and practices should increase their capacity to look at learning communities through appropriate “networking-sensitive” glasses, and get equipped with tools and methods – such as Social network Analysis - to properly understand and support these networks. The application of Social Network Analysis to education, especially in the case of distance learning, can allow understanding the patterns of interactions between teachers and learners, and can facilitate the consolidation of new approaches to understand collaboration mechanisms. The paper presents and discusses - from a learning viewpoint - a brief overview of the main theoretical and practical contributions coming from Social Network Analysis – such as the “random graphs”, the “small-worlds” or the “weak-ties” theories – together with some general

    Full Text Available A modified DIA type multi-anvil apparatus was installed in the Department of Earth Sciences, National Cheng Kung University, Taiwan. This modified DIA multi-anvil system is used with a hydraulic press that generates loads of up to 1000 tons and is the first multi-anvil press installed for geoscience research in Taiwan. In this paper, the geometry of the high-pressure apparatus is briefly described and the pressure calibration performed in the press is reported. The thermal behaviors of various pressure mediums, boron-epoxy, zirconia, and mullite, are also compared. Pressure calibrations at room temperature were performed with different cell designs, paying special attention to the so called ¡§D¡¨ factor, which is defined as the ratio of diagonal length of the cell assembly cube to the diameter of the cavity hole. For a given cell design, the sample-pressur
