    Full Text Available In recent years there has been an increased emphasis on science learning in 4-H and other youth development programs. In an effort to increase science capacity in youth, it is easy to focus only on developing the concrete skills and knowledge that a trained scientist must possess. However, when science learning is presented in a youth-development setting, the context of the program also matters. This paper reports the development and testing of the Science Process Skills Inventory (SPSI and its usefulness for measuring science inquiry skill development in youth development science programs. The results of the psychometric testing of the SPSI indicated the instrument is reliable and measures a cohesive construct called science process skills, as reflected in the 11 items that make up this group of skills. The 11 items themselves are based on the cycle of science inquiry, and represent the important steps of the complete inquiry process.

    Brumfield, Teresa E.

    In 2002, a math-science partnership (MSP) program was initiated by a national science grant. The purpose of the MSP program was to promote the development, implementation, and sustainability of promising partnerships among institutions of higher education, K-12 schools and school systems, as well as other important stakeholders. One of the funded projects included a teacher-scientist collaborative that instituted a professional development system to prepare teachers to use inquiry-based instructional modules. The MSP program mandated evaluations of its funded projects. One of the teacher-scientist collaborative project's outcomes specifically focused on teacher and student science content and process skills. In order to provide annual evidence of progress and to measure the impact of the project's efforts, and because no appropriate science tests were available to measure improvements in content knowledge of participating teachers and their students, the project contracted for the development of science tests. This dissertation focused on the process of test development within an evaluation and examined planned (i.e., expected) and actual (i.e., observed) test development, specifically concentrating on the factors that affected the actual test development process. Planned test development was defined as the process of creating tests according to the well-established test development procedures recommended by the AERA/APA/NCME 1999 Standards for Educational and Psychological Testing. Actual test development was defined as the process of creating tests as it actually took place. Because case study provides an in-depth, longitudinal examination of an event (i.e., case) in a naturalistic setting, it was selected as the appropriate methodology to examine the difference between planned and actual test development. The case (or unit of analysis) was the test development task, a task that was bounded by the context in which it occurred---and over which this researcher had

  7. Developing Elementary Math and Science Process Skills Through Engineering Design Instruction

    Science.gov (United States)

    Strong, Matthew G.

    This paper examines how elementary students can develop math and science process skills through an engineering design approach to instruction. The performance and development of individual process skills overall and by gender were also examined. The study, preceded by a pilot, took place in a grade four extracurricular engineering design program in a public, suburban school district. Students worked in pairs and small groups to design and construct airplane models from styrofoam, paper clips, and toothpicks. The development and performance of process skills were assessed through a student survey of learning gains, an engineering design packet rubric (student work), observation field notes, and focus group notes. The results indicate that students can significantly develop process skills, that female students may develop process skills through engineering design better than male students, and that engineering design is most helpful for developing the measuring, suggesting improvements, and observing process skills. The study suggests that a more regular engineering design program or curriculum could be beneficial for students' math and science abilities both in this school and for the elementary field as a whole.

    The purpose of the study was to determine factors associated with staff development processes and the creation of innovative science courses by higher education faculty who have participated in a model staff development project. The staff development program was designed for college faculty interested in creating interdisciplinary, constructivist-based science, mathematics, or engineering courses designed for non-majors. The program includes workshops on incorporating constructivist pedagogy, alternative assessment, and technology into interdisciplinary courses. Staff development interventions used in the program include grant opportunities, distribution of resource materials, and peer mentoring. University teams attending the workshops are comprised of faculty from the sciences, mathematics, or engineering, as well as education, and administration. A purposeful and convenient sample of three university teams were subjects for this qualitative study. Each team had attended a NASA Opportunities for Visionary Academics (NOVA) workshop, received funding for course development, and offered innovative courses. Five questions were addressed in this study: (a) What methods were used by faculty teams in planning the courses? (b) What changes occurred in existing science courses? (c) What factors affected the team collaboration process? (d) What personal characteristics of faculty members were important in successful course development? and (e) What barriers existed for faculty in the course development process? Data was collected at each site through individual faculty interviews (N = 11), student focus group interviews (N = 15), and classroom observations. Secondary data included original funding proposals. The NOVA staff development model incorporated effective K--12 interventions with higher education interventions. Analysis of data revealed that there were four factors of staff development processes that were most beneficial. First, the team collaborative processes

    Full Text Available Cognitive science is a science which studies how human mental processes to influence one’s behavior. Principal major issue that needs to be known in the understanding of cognitive science and their development is related to how the initial state of cognitive science itself, the mind is adapted, the development process starting from the concrete to the abstract, the conceptual nature of the change, the difference between learning and development, format representation of the underlying changes in development, the role of implicit and explicit cognitions in the development, the role of the association and the rules in the development, the universal development, cognitive domain and how to influence the development of brain structure. There are three difference in the cognitive domain of the most common sense that domain as a module, as the domain of expertise, and domain as a model of mind.   Ilmu kognitif adalah suatu pengetahuan yang mempelajari tentang bagaimana proses mental manusia dalam mempengaruhi perilaku seseorang. Pokok pembahasan utama yang perlu diketahui dalam memahami ilmu kognitif dan perkembangannya yaitu terkait dengan bagaimana keadaan awal dari ilmu kognitif itu sendiri, pikiran yang teradaptasi, proses perkembangan mulai dari hal yang kongkrit sampai dengan abstrak, sifat konseptual dalam perubahan, perbedaan antara belajar dan pengembangan, format representasi yang mendasari perubahan dalam perkembangan, peran kognisi implisit dan eksplisit dalam perkembangan, peran asosiasi dan aturan dalam perkembangan, perkembangan secara universal, domain kognitif dan bagaimana struktur otak mempengaruhi perkembangan.

    2006-09-01

    There has been considerable discussion about translating science into practical messages, especially among urban minority and "hard-to-reach" populations. Unfortunately, many research findings rarely make it back in useful format to the general public. Few innovative techniques have been established that provide researchers with a systematic process for developing health awareness and prevention messages for priority populations. The purpose of this paper is to describe the early development and experience of a unique community-based participatory process used to develop health promotion messages for a predominantly low-income, black and African-American community in Baltimore, MD. Scientific research findings from peer-reviewed literature were identified by academic researchers. Researchers then taught the science to graphic design students and faculty. The graphic design students and faculty then worked with both community residents and researchers to transform this information into evidence-based public health education messages. The final products were culturally and educationally appropriate, health promotion messages reflecting urban imagery that were eagerly desired by the community. This early outcome is in contrast to many previously developed messages and materials created through processes with limited community involvement and by individuals with limited practical knowledge of local community culture or expertise in marketing or mass communication. This process may potentially be utilized as a community-based participatory approach to enhance the translation of scientific research into desirable and appropriate health education messages.

  11. Developing Engineering and Science Process Skills Using Design Software in an Elementary Education

    Fusco, Christopher

    This paper examines the development of process skills through an engineering design approach to instruction in an elementary lesson that combines Science, Technology, Engineering, and Math (STEM). The study took place with 25 fifth graders in a public, suburban school district. Students worked in groups of five to design and construct model bridges based on research involving bridge building design software. The assessment was framed around individual student success as well as overall group processing skills. These skills were assessed through an engineering design packet rubric (student work), student surveys of learning gains, observation field notes, and pre- and post-assessment data. The results indicate that students can successfully utilize design software to inform constructions of model bridges, develop science process skills through problem based learning, and understand academic concepts through a design project. The final result of this study shows that design engineering is effective for developing cooperative learning skills. The study suggests that an engineering program offered as an elective or as part of the mandatory curriculum could be beneficial for developing students' critical thinking, inter- and intra-personal skills, along with an increased their understanding and awareness for scientific phenomena. In conclusion, combining a design approach to instruction with STEM can increase efficiency in these areas, generate meaningful learning, and influence student attitudes throughout their education.

    2016-04-01

    A novel functional-genomics based concept of pharmacology that uses artificial intelligence techniques for mining and knowledge discovery in "big data" providing comprehensive information about the drugs' targets and their functional genomics is proposed. In "process pharmacology", drugs are associated with biological processes. This puts the disease, regarded as alterations in the activity in one or several cellular processes, in the focus of drug therapy. In this setting, the molecular drug targets are merely intermediates. The identification of drugs for therapeutic or repurposing is based on similarities in the high-dimensional space of the biological processes that a drug influences. Applying this principle to data associated with lymphoblastic leukemia identified a short list of candidate drugs, including one that was recently proposed as novel rescue medication for lymphocytic leukemia. The pharmacological data science approach provides successful selections of drug candidates within development and repurposing tasks. © 2016 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

    Germann, Paul J.

    Path analysis techniques were used to test a hypothesized structural model of direct and indirect causal effects of student variables on science process skills. The model was tested twice using data collected at the beginning and end of the school year from 67 9th- and 10th-grade biology students who lived in a rural Franco-American community in New England. Each student variable was found to have significant effects, accounting for approximately 80% of the variance in science process skills achievement. Academic ability, biology knowledge, and language preference had significant direct effects. There were significant mediated effects by cognitive development, parents' education, and attitude toward science in school. The variables of cognitive development and academic ability had the greatest total effects on science process skills. Implications for practitioners and researchers are discussed.

  1. The role of science in environmental impact assessment: process and procedure versus purpose in the development of theory

    International Nuclear Information System (INIS)

    Cashmore, Matthew

    2004-01-01

    Increasing emphasis has been placed in recent years on development of the theory of Environmental Impact Assessment (EIA), primarily as a consequence of increasing recognition that the theoretical basis of 'state-of-the-art' EIA is inadequately developed and detailed. This study reviews consideration given in the research literature to the role of science in EIA in order to identify implicit theories. It is suggested that there are two main interpretations of the role of science in EIA (EIA as applied science and EIA as civic science) and five distinct models are identified within these paradigms. These models appear to be based predominantly on existing philosophies of science (such as positivism or relativism) and simplistic and ill-defined conceptions of the purposes of EIA. A broad model is proposed for the advancement of theory regarding the role of science in EIA which emphasises conceptual consideration and empirical investigation of the purposes, and hence outcomes, of EIA and the causal processes utilised to achieve these purposes. The model necessitates a reorientation of the research agenda, away from process and procedure to focus on substantive purposes, and this will require more integrative and connective research than has been commonplace in the past. The EIA research agenda must evolve and mature if this globally significant decision tool is to fulfil its potential

    Full Text Available This paper explores a new idea about the future development of science and teams, and predicts its possible applications in science, education, workforce development and research. The inter-relatedness of science and teamwork developments suggests a growing importance of team facilitators’ quality, as well as the criticality of detailed studies of teamwork processes and team consortiums to address the increasing complexity of exponential knowledge growth and work interdependency. In the future, it will become much easier to produce a highly specialised workforce, such as brain surgeons or genome engineers, than to identify, educate and develop individuals capable of the delicate and complex work of multi-team facilitation. Such individuals will become the new scientists of the millennium, having extraordinary knowledge in variety of scientific fields, unusual mix of abilities, possessing highly developed interpersonal and teamwork skills, and visionary ideas in illuminating bold strategies for new scientific discoveries. The new scientists of the millennium, through team consortium facilitation, will be able to build bridges between the multitude of diverse and extremely specialised knowledge and interdependent functions to improve systems for the further benefit of mankind.

  5. Examining the Affordances of Dual Cognitive Processing to Explain the Development of High School Students' Nature of Science Views

    Science.gov (United States)

    Jackson, Luke M.

    This mixed method study was aimed at examining the influence of dual processing (Type 1 and Type 2 thinking) on the development of high school students' nature of science (NOS) views. Type 1 thinking is intuitive, experiential, and heuristic. Type 2 thinking is rational, analytical, and explicit. Three research questions were asked: (1) Do the experiential process (Type 1) and the logical process (Type 2) influence the development of students' NOS views? (2) If there is an influence on students' NOS views, then what is the nature of relationship between the experiential process (Type 1) and the development of NOS views? (3) What is the nature of relationship between the logical process (Type 2) and the development of NOS views? The Views of Nature of Science Questionnaire C (VNOS-C; Lederman, Abd-El-Khalick, Bell, & Schwartz, 2002) was administered to 29 high school students at the beginning and at the end of an explicit-reflective NOS intervention offered in an Advanced Placement environmental science course. Changes in students' NOS views were calculated through a chi-square test and examining the percentage of students holding NOS views at various levels of sophistication. With the chi-square goodness of fit test performed, the relationship between pre and post NOS scores was not significant, X2(3, 29) = 4.78, p <.05. The informed and preinformed NOS views increased (14%, 17%) in frequency while the mixed and uninformed NOS views decreased (i.e. improved 26%, 24%) in frequency from pre to posttest. The reading discussions were coded based on the EBR framework (Furtak et al., 2010) to analyze the use of dual processing. Type1 and Type 2 thinking were both used during the intervention and reading reflections. Type 2 thinking was more prominent when analyzing a problem, formulating a hypothesis, or stating logical claims. The association of NOS education and Type 1 and Type 2 thinking in scientific literacy was examined, and implications and future research are

    The document represents an attempt to put together, in one place, a summary of the present state of knowledge concerning those processes that affect air concentrations of acidic and acidifying pollutants, during their transport, from emission to deposition. It is not intended to be an all-encompassing review of the entire breadth of each of the contributing disciplines, but instead focuses on those areas where the state of science has improved over the last decade--the period of the National Acid Precipitation Assessment Program. The discussion is not limited to NAPAP activities, although it is clear that the products of NAPAP research are perhaps given greater attention than are the results obtained elsewhere. This bias is partially intentional, since it is the INTEGRATED ASSESSMENT that is currently being prepared by NAPAP that constitutes the 'client' for the material presented here. The integrated assessment pay attention to the North American situation alone, and hence the present work gives greatest attention to the North American case, but with awareness of the need to place this particular situation in the context of the rest of the world

    Full Text Available In Cuba and other countries of Latin America are thousands of professionals graduated in the economic sciences that are working as specialists, officials and directive in companies, organisms and entities of the central administration of the state, as well as professors and investigators in universities and centers and institutes of scientific investigations. Many of them have developed diverse study, organized in masters courses, and want to continue their professional development in order to obtaining of doctor's scientific grade, but many of them ignore the form and the roads to be able to reach this purpose. Doctor`s degree in specialties of economics sciences is possible to obtain in Cuba. It is generally achieved in time shared with the applicant's habitual work, usually in one period between 3 and 5 years, by programs of study of curricular doctorate or through topics framed in investigation projects approved by the Ministry of Sciences, Technology and Environment, which is directed with academic rigor by the National Commission of Scientific Grades and by means of the guide of each applicant's individual program, by a professional of prestige that shows doctor's grade who acts as tutor. The  central objective of the present work is to explain the main characteristics of the process to carry out the doctorate studies in economic sciences in Cuba, the requirements and the main roads to carry out them with the elaboration of the grade thesis and its defense in the Permanent National Tribunal of Scientific Grades of each specialty of the economic sciences, as well as some considerations regarding the elements that cannot be outside in the design of the investigation.

    2016-06-01

    This paper examines the name as an issue of interest in the psychology field. In thinking about the role played by names for some of the most important approaches on the psychology panorama, it has been found that the analysis of names can be used as an instrument for the investigation of thought formation processes, or as an element in the process of constructing personal identity. In the first case, the focus is on the so-called "common" names, which designate objects; in the second case, instead, it is on people's given names and on the way they are perceived by their bearers and those who surround them. We have examined both domains, since it is essential to understand how the psychological concepts related to names develop in children's minds, if we aim to grasp their importance as designators of people's internal and external realities. Lastly, we have proposed our own view of the person's name, linked to the relational systems perspective which essentially sees the name as a signifier or "representative" of the child-parent relationship, while the "relationship" is the signified.

    In 2001, NASA Goddard Space Flight Center's Laboratory for Terrestrial Physics started the construction of a science Investigator-led Processing System (SIPS) for processing data from the Ozone Monitoring Instrument (OMI) which will launch on the Aura platform in mid 2004. The Ozone Monitoring Instrument (OMI) is a contribution of the Netherlands Agency for Aerospace Programs (NIVR) in collaboration with the Finnish Meteorological Institute (FMI) to the Earth Observing System (EOS) Aura mission. It will continue the Total Ozone Monitoring System (TOMS) record for total ozone and other atmospheric parameters related to ozone chemistry and climate. OMI measurements will be highly synergistic with the other instruments on the EOS Aura platform. The LTP previously developed the Moderate Resolution Imaging Spectrometer (MODIS) Data Processing System (MODAPS), which has been in full operations since the launches of the Terra and Aqua spacecrafts in December, 1999 and May, 2002 respectively. During that time, it has continually evolved to better support the needs of the MODIS team. We now run multiple instances of the system managing faster than real time reprocessings of the data as well as continuing forward processing. The new OMI Data Processing System (OMIDAPS) was adapted from the MODAPS. It will ingest raw data from the satellite ground station and process it to produce calibrated, geolocated higher level data products. These data products will be transmitted to the Goddard Distributed Active Archive Center (GDAAC) instance of the Earth Observing System (EOS) Data and Information System (EOSDIS) for long term archive and distribution to the public. The OMIDAPS will also provide data distribution to the OMI Science Team for quality assessment, algorithm improvement, calibration, etc. We have taken advantage of lessons learned from the MODIS experience and software already developed for MODIS. We made some changes in the hardware system organization, database and

  10. Payoffs of science for development

    Frame, J D

    1979-09-01

    An examination is made of the interrelationship between science, technology, productivity, and economic development to determine the economic and non-economic payoffs of science to national development. It is seen that their interactions are complex and difficult to measure. The link between science and technology is also ambiguous, technological developments often having no immediate scientific antecedents or technological applications; and it is evident that an investment in basic science will not automatically yield economic development payoffs. Seven basic payoffs of science to development are identified: (1) indigenous scientific capabilities enable less-developed countries (LDCs) to engage in scientific research that is directed toward national needs; (2) existence of indigenous scientific capabilities facilitates training of professionals who are key personnel in the development process (doctors, medical technicians, teachers, engineers); (3) indigenous science will strengthen the general problem-solving capabilities of LDCs; (4) indigenous scientific capabilities will reduce LDC dependence on outsiders; (5) existence of an indigenous scientific establishment in LDCs may enhance their ability to adapt imported technologies to local conditions; (6) indigenous science can help LDCs improve their foreign trade position; and (7) science will satisfy certain aesthetic and spiritual needs of LDC scientists who engage in it. 33 references.

  15. Science transfer for development

    Salam, A.

    1985-01-01

    Despite the recent realisation that science and technology are the sustenance and major hope for economic betterment, the third world, barring a few countries like Argentina, Brazil, China and India, has taken to science - as distinct from technology - as only a marginal activity. This is also true of the aid - giving agencies of the richer countries, of the agencies of the UN and also unfortunately of the scientific communities of the developed countries which might naturally be expected to be the Third World's foremost allies. Policy makers, prestigious commissions (like the Brandt Commission) as well as aid-givers, speak uniformly of problems of technology transfer to the developing countries as if that is all that is involved. Very few within the developing world appear to stress that for long term effectiveness, technology transfers must always be accompanied by science transfers; that the science of today is the technology of tomorrow. Science transfer is effected by and to communities of scientists. Such communities (in developing countries) need building up to a critical size in their human resources and infrastructure. This building up calls for wise science policies, with long term commitment, generous patronage, self governance and free international contacts. Further, in our countries, the high level scientist must be allowed to play a role in nation building as an equal partner to the professional planner, the economist and the technologist. Few developing countries have promulgated such policies: few aid agencies have taken it as their mandate to encourage and help build up the scientific infrastructure. (author)

    Policy makers can implement more effective climate change adaptation programs if they are provided with two tools: accessible information on the impacts that they need to prepare for, and clear guidance on how to integrate climate change considerations into their work. This presentation will highlight recent and ongoing efforts at the City of Philadelphia to integrate climate science into their decision-making. These efforts include developing a climate change information visualization tool, climate change risk assessments across the city, and processes to integrate climate change into routine planning and budgeting practices. The goal of these efforts is to make climate change science highly targeted to decision maker needs, non-political, easily accessible, and actionable. While sea level rise inundation maps have been available to communities for years, the maps do not effectively communicate how the design of a building or a piece of infrastructure would need to be modified to protect it. The Philadelphia Flood Risk Viewer is an interactive planning tool that allows Philadelphia to identify projected depths of flooding for any location within the City, for a variety of sea level rise and storm surge scenarios. Users can also determine whether a location is located in a FEMA floodplain. By having access to information on the projected depth of flooding at a given location, the City can determine what flood protection measures may be effective, or even inform the long-term viability of developing a particular area. With an understanding of climate vulnerabilities, cities have the opportunity to make smart, climate-resilient investments with their capital budgets that will yield multiple benefits for years to come. Few, however, have established protocols for doing so. Philadelphia, with support from ICF, developed a guidance document that identifies recommendations for integrating climate change considerations throughout the Capital Program and capital budgeting

    "This article is intended as a manifesto for an economic theory of scientific inquiry. My focus is not on traditional economic concerns about how societal resources are allocated to the funding of science and how scientific research contributes to technological advances and economic growth. Rather, my attention centers on using economic concepts to illuminate the conduct of scientific inquiry itself" (5 pages).

    `It's Our Fault' (IOF) is an end-to-end research programme aimed at positioning Wellington, the capital city of New Zealand, to become a more resilient city through a comprehensive study of the likelihood of large Wellington earthquakes, the effects of these earthquakes, and their impacts on humans and the built environment. For over 10 years the IOF programme has facilitated end-user engagement, and produced a great number of publications on the results of the hazard and risk research. Nevertheless, much of this research was not being applied to local council policies being formulated to intensify development in one of the most susceptible locations in the Wellington region. We explore why this was the case, and offer suggestions on how to bridge the gap between science and practice.The example is a statutory plan change which allowed for an increased level of development and encouraged mixed-use development in a location of high susceptibility from multiple hazards including fault rupture, ground shaking, subsidence, sea level rise, liquefaction, flooding, and tsunami. Prior to the plan change, the land use was predominantly business and commercial; this plan change proposed introducing residential, educational and emergency facilities, thereby increasing exposure within an area already known to be "risky". Being a good `corporate citizen' of the city involved, GNS Science lodged a submission opposing the plan change based on the range of natural hazards that were not addressed in the plan change. Scientists were involved in public meetings, met with the Mayor, and attended a hearing. While the plan change still went ahead, natural hazard provisions were improved through the submission process. Many aspects of the submission were based around communicating the natural hazard research undertaken within the IOF project.Land use planning provides a key opportunity to reduce future risks from natural hazards, and scientist have a key role in contributing to

    2017-09-01

    As part of their professional competencies, science teachers need an elaborate meta-modelling knowledge as well as modelling skills in order to guide and monitor modelling practices of their students. However, qualitative studies about (pre-service) science teachers' modelling practices are rare. This study provides a category system which is suitable to analyse and to describe pre-service science teachers' modelling activities and to infer modelling strategies. The category system was developed based on theoretical considerations and was inductively refined within the methodological frame of qualitative content analysis. For the inductive refinement, modelling practices of pre-service teachers (n = 4) have been video-taped and analysed. In this study, one case was selected to demonstrate the application of the category system to infer modelling strategies. The contribution of this study for science education research and science teacher education is discussed.

    We give an overview of the operational concepts and architecture of the Kepler Science Processing Pipeline. Designed, developed, operated, and maintained by the Kepler Science Operations Center (SOC) at NASA Ames Research Center, the Science Processing Pipeline is a central element of the Kepler Ground Data System. The SOC consists of an office at Ames Research Center, software development and operations departments, and a data center which hosts the computers required to perform data analysis. The SOC's charter is to analyze stellar photometric data from the Kepler spacecraft and report results to the Kepler Science Office for further analysis. We describe how this is accomplished via the Kepler Science Processing Pipeline, including, the software algorithms. We present the high-performance, parallel computing software modules of the pipeline that perform transit photometry, pixel-level calibration, systematic error correction, attitude determination, stellar target management, and instrument characterization.

    1988-09-01

    The theme of this talk will be to illustrate examples of technologies that will drive materials and processing sciences to the limit and to describe some of the research being pursued to understand materials interactions which are pervasive to projected structure fabrication. It is to be expected that the future will see a progression to nanostructures where scaling laws will be tested and quantum transport will become more in evidence, to low temperature operation for tighter control and improved performance, to complex vertical profiles where 3D stacking and superlattices will produce denser packing and device flexibility, to faster communication links with optoelectronics, and to compatible packaging technologies. New low temperature processing techniques, such as epitaxy of silicon, PECVD of dielectrics, low temperature high pressure oxidation, silicon-germanium heterostructures, etc., must be combined with shallow metallurgies, new lithographic technologies, maskless patterning, rapid thermal processing (RTP) to produce needed profile control, reduce process incompatibilities and develop new device geometries. Materials interactions are of special consequence for chip substrates and illustrations of work in metal-ceramic and metal-polymer adhesion will be offered.

    A JPL-created set of standard processes is to be used throughout the lifecycle of software development. These SDSPs cover a range of activities, from management and engineering activities, to assurance and support activities. These processes must be applied to software tasks per a prescribed set of procedures. JPL s Software Quality Improvement Project is currently working at the behest of the JPL Software Process Owner to ensure that all applicable software tasks follow these procedures. The SDSPs are captured as a set of 22 standards in JPL s software process domain. They were developed in-house at JPL by a number of Subject Matter Experts (SMEs) residing primarily within the Engineering and Science Directorate, but also from the Business Operations Directorate and Safety and Mission Success Directorate. These practices include not only currently performed best practices, but also JPL-desired future practices in key thrust areas like software architecting and software reuse analysis. Additionally, these SDSPs conform to many standards and requirements to which JPL projects are beholden.

  12. A phenomenological investigation of science center exhibition developers' expertise development

    Young, Denise L.

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

    The Internet hosts an abundance of science video resources aimed at communicating scientific knowledge, including webinars, massive open online courses, and TED talks. Although these videos are efficient at disseminating information for diverse types of users, they often do not demonstrate the process of doing science, the excitement of scientific discovery, or how new scientific knowledge is developed. iBiology (www.ibiology.org), a project that creates open-access science videos about biology research and science-related topics, seeks to fill this need by producing videos by science leaders that make their ideas, stories, and experiences available to anyone with an Internet connection. © 2014 Goodwin.

  17. Citizen Science: Opportunities for Girls' Development of Science Identity

    Science.gov (United States)

    Brien, Sinead Carroll

    Many students in the United States, particularly girls, have lost interest in science by the time they reach high school and do not pursue higher degrees or careers in science. Several science education researchers have found that the ways in which youth see themselves and position themselves in relation to science can influence whether they pursue science studies and careers. I suggest that participation in a citizen science program, which I define as a program in which girls interact with professional scientists and collect data that contributes to scientific research, could contribute to changing girls' perceptions of science and scientists, and promote their science identity work. I refer to science identity as self-recognition and recognition by others that one thinks scientifically and does scientific work. I examined a case study to document and analyze the relationship between girls' participation in a summer citizen science project and their development of science identity. I observed six girls between the ages of 16 and 18 during the Milkweed and Monarch Project, taking field notes on focal girls' interactions with other youth, adults, and the scientist, conducted highly-structured interviews both pre-and post- girls' program participation, and interviewed the project scientist and educator. I qualitatively analyzed field notes and interview responses for themes in girls' discussion of what it meant to think scientifically, roles they took on, and how they recognized themselves as thinking scientifically. I found that girls who saw themselves as thinking scientifically during the program seemed to demonstrate shifts in their science identity. The aspects of the citizen science program that seemed to most influence shifts in these girls' science identities were 1) the framing of the project work as "real science, 2) that it involved ecological field work, and 3) that it created a culture that valued data and scientific work. However, some of the girls only

    The silicon web process takes advantage of natural crystallographic stabilizing forces to grow long, thin single crystal ribbons directly from liquid silicon. The ribbon, or web, is formed by the solidification of a liquid film supported by surface tension between two silicon filaments, called dendrites, which border the edges of the growing strip. The ribbon can be propagated indefinitely by replenishing the liquid silicon as it is transformed to crystal. The dendritic web process has several advantages for achieving low cost, high efficiency solar cells. These advantages are discussed.

  1. Framework for Processing Citizens Science Data for Applications to NASA Earth Science Missions

    Teng, William; Albayrak, Arif

    2017-01-01

    Citizen science (or crowdsourcing) has drawn much high-level recent and ongoing interest and support. It is poised to be applied, beyond the by-now fairly familiar use of, e.g., Twitter for natural hazards monitoring, to science research, such as augmenting the validation of NASA earth science mission data. This interest and support is seen in the 2014 National Plan for Civil Earth Observations, the 2015 White House forum on citizen science and crowdsourcing, the ongoing Senate Bill 2013 (Crowdsourcing and Citizen Science Act of 2015), the recent (August 2016) Open Geospatial Consortium (OGC) call for public participation in its newly-established Citizen Science Domain Working Group, and NASA's initiation of a new Citizen Science for Earth Systems Program (along with its first citizen science-focused solicitation for proposals). Over the past several years, we have been exploring the feasibility of extracting from the Twitter data stream useful information for application to NASA precipitation research, with both "passive" and "active" participation by the twitterers. The Twitter database, which recently passed its tenth anniversary, is potentially a rich source of real-time and historical global information for science applications. The time-varying set of "precipitation" tweets can be thought of as an organic network of rain gauges, potentially providing a widespread view of precipitation occurrence. The validation of satellite precipitation estimates is challenging, because many regions lack data or access to data, especially outside of the U.S. and in remote and developing areas. Mining the Twitter stream could augment these validation programs and, potentially, help tune existing algorithms. Our ongoing work, though exploratory, has resulted in key components for processing and managing tweets, including the capabilities to filter the Twitter stream in real time, to extract location information, to filter for exact phrases, and to plot tweet distributions.

    The basic methods for processing ore to recover the contained uranium have not changed significantly since the 1954-62 period. Improvements in mill operations have been the result of better or less expensive reagents, changes in equipment, and in the successful resolvement of many environmental matters. There is also an apparent trend toward large mills that can profitably process lower grade ores. The major thrust in the near future will not be on process technology but on the remaining environmental constraints associated with milling. At this time the main ''spot light'' is on tailings dam and impoundment area construction and reclamation. Plans must provide for an adequate safety factor for stability, no surface or groundwater contamination, and minimal discharge of radionuclides to unrestricted areas, as may be required by law. Solution mining methods must also provide for plans to restore the groundwater back to its original condition as defined by local groundwater regulations.

  5. Philosophy of science and the diagnostic process.

    Science.gov (United States)

    Willis, Brian H; Beebee, Helen; Lasserson, Daniel S

    2013-10-01

    This is an overview of the principles that underpin philosophy of science and how they may provide a framework for the diagnostic process. Although philosophy dates back to antiquity, it is only more recently that philosophers have begun to enunciate the scientific method. Since Aristotle formulated deduction, other modes of reasoning including induction, inference to best explanation, falsificationism, theory-laden observations and Bayesian inference have emerged. Thus, rather than representing a single overriding dogma, the scientific method is a toolkit of ideas and principles of reasoning. Here we demonstrate that the diagnostic process is an example of science in action and is therefore subject to the principles encompassed by the scientific method. Although a number of the different forms of reasoning are used readily by clinicians in practice, without a clear understanding of their pitfalls and the assumptions on which they are based, it leaves doctors open to diagnostic error. We conclude by providing a case example from the medico-legal literature in which diagnostic errors were made, to illustrate how applying the scientific method may mitigate the chance for diagnostic error.

    2015-12-01

    Since 2008, NASA's Earth Science Technology Office and the Advanced Information Systems Technology Program have invested in two technology evolutions to meet the needs of the community of scientists exploiting the rapidly growing database of international synthetic aperture radar (SAR) data. JPL, working with the science community, has developed the InSAR Scientific Computing Environment (ISCE), a next-generation interferometric SAR processing system that is designed to be flexible and extensible. ISCE currently supports many international space borne data sets but has been primarily focused on geodetic science and applications. A second evolutionary path, the Advanced Rapid Imaging and Analysis (ARIA) science data system, uses ISCE as its core science data processing engine and produces automated science and response products, quality assessments and metadata. The success of this two-front effort has been demonstrated in NASA's ability to respond to recent events with useful disaster support. JPL has enabled high-volume and low latency data production by the re-use of the hybrid cloud computing science data system (HySDS) that runs ARIA, leveraging on-premise cloud computing assets that are able to burst onto the Amazon Web Services (AWS) services as needed. Beyond geodetic applications, needs have emerged to process large volumes of time-series SAR data collected for estimation of biomass and its change, in such campaigns as the upcoming AfriSAR field campaign. ESTO is funding JPL to extend the ISCE-ARIA model to a "SAR Science Data Processing Foundry" to on-ramp new data sources and to produce new science data products to meet the needs of science teams and, in general, science community members. An extension of the ISCE-ARIA model to support on-demand processing will permit PIs to leverage this Foundry to produce data products from accepted data sources when they need them. This paper will describe each of the elements of the SAR SDP Foundry and describe their

    Broadly, this project involved the development and delivery of a new curriculum in wind energy engineering at the Pennsylvania State University; this includes enhancement of the Renewable Energy program at the Pennsylvania College of Technology. The new curricula at Penn State includes addition of wind energy-focused material in more than five existing courses in aerospace engineering, mechanical engineering, engineering science and mechanics and energy engineering, as well as three new online graduate courses. The online graduate courses represent a stand-alone Graduate Certificate in Wind Energy, and provide the core of a Wind Energy Option in an online intercollege professional Masters degree in Renewable Energy and Sustainability Systems. The Pennsylvania College of Technology erected a 10 kilowatt Xzeres wind turbine that is dedicated to educating the renewable energy workforce. The entire construction process was incorporated into the Renewable Energy A.A.S. degree program, the Building Science and Sustainable Design B.S. program, and other construction-related coursework throughout the School of Construction and Design Technologies. Follow-on outcomes include additional non-credit opportunities as well as secondary school career readiness events, community outreach activities, and public awareness postings.

    Cleaning up the nation's nuclear weapons complex remains as one of the most technologically challenging and financially costly problems facing the U.S. Department of Energy (DOE). Safety, cost, and technological challenges have often delayed progress in retrieval, processing, and final disposition of high-level waste, spent nuclear fuel, and challenging materials. Some of the issues result from the difficulty and complexity of the technological issues; others have programmatic bases, such as contracting strategies that may provide undue focus on near-term, specific clean-up goals or difficulty in developing and maintaining stakeholder confidence in the proposed solutions. We propose that independent basic fundamental science research focused on the full cleanup life-cycle offers an opportunity to help address these challenges by providing (1) scientific insight into the fundamental mechanisms involved in currently selected processing and disposal options, (2) a rational path to the development of alternative technologies should the primary options fail, (3) confidence that models that predict long-term performance of different disposal options are based upon the best available science, (4) fundamental science discovery that enables transformational solutions to revolutionize the current baseline processes.

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

    Panagiotis Tsakanikas

    Full Text Available Recently, machine vision is gaining attention in food science as well as in food industry concerning food quality assessment and monitoring. Into the framework of implementation of Process Analytical Technology (PAT in the food industry, image processing can be used not only in estimation and even prediction of food quality but also in detection of adulteration. Towards these applications on food science, we present here a novel methodology for automated image analysis of several kinds of food products e.g. meat, vanilla crème and table olives, so as to increase objectivity, data reproducibility, low cost information extraction and faster quality assessment, without human intervention. Image processing's outcome will be propagated to the downstream analysis. The developed multispectral image processing method is based on unsupervised machine learning approach (Gaussian Mixture Models and a novel unsupervised scheme of spectral band selection for segmentation process optimization. Through the evaluation we prove its efficiency and robustness against the currently available semi-manual software, showing that the developed method is a high throughput approach appropriate for massive data extraction from food samples.

    The history of science has gone through cycles among nations. In the period of antiquity the centres of science were in the East; in the middle ages scholars from the underdeveloped West travelled to the centres of study and research of the rich countries in the East to learn from the teachers there. In our century the cycle has turned and it is the East that turns to the West for science. Opportunities for scientists from developing countries are diminishing, however, and it is important that centres like the International Centre for Theoretical Physics in Trieste, supported by the IAEA, UNESCO and the Government of Italy, be provided with continuing and strong support

    The Science Gateway Institute (SGW-I) for the Democratization and Acceleration of Science was a SI2-SSE Collaborative Research conceptualization award funded by NSF in 2012. From 2012 through 2015, we engaged interested members of the science and engineering community in a planning process for a Science Gateway Community Institute (SGCI). Science Gateways provide Web interfaces to some of the most sophisticated cyberinfrastructure resources. They interact with remotely executing science applications on supercomputers, they connect to remote scientific data collections, instruments and sensor streams, and support large collaborations. Gateways allow scientists to concentrate on the most challenging science problems while underlying components such as computing architectures and interfaces to data collection changes. The goal of our institute was to provide coordinating activities across the National Science Foundation, eventually providing services more broadly to projects funded by other agencies. SGW-I has succeeded in identifying two underrepresented communities of future gateway designers and users. The Association of Computer and Information Science/Engineering Departments at Minority Institutions (ADMI) was identified as a source of future gateway designers. The National Organization for the Professional Advancement of Black Chemists and Chemical Engineers (NOBCChE) was identified as a community of future science gateway users. SGW-I efforts to engage NOBCChE and ADMI faculty and students in SGW-I are now woven into the workforce development component of SGCI. SGCI (ScienceGateways.org ) is a collaboration of six universities, led by San Diego Supercomputer Center. The workforce development component is led by Elizabeth City State University (ECSU). ECSU efforts focus is on: Produce a model of engagement; Integration of research into education; and Mentoring of students while aggressively addressing diversity.

    2012-01-01

    A computer can handle the volume but cannot make sense of the language. This paper reviews and discusses the use of natural language processing (NLP and machine-learning algorithms to extract information from systematic literature. NLP algorithms have been used for decades, but require special development for application in the biological realm due to the special nature of the language. Many tools exist for biological information extraction (cellular processes, taxonomic names, and morphological characters, but none have been applied life wide and most still require testing and development. Progress has been made in developing algorithms for automated annotation of taxonomic text, identification of taxonomic names in text, and extraction of morphological character information from taxonomic descriptions. This manuscript will briefly discuss the key steps in applying information extraction tools to enhance biodiversity science.

    2017-01-01

    This paper presents a software development process for safety-critical software components of cyber-physical systems. The process is called MINERVA, which stands for Mirrored Implementation Numerically Evaluated against Rigorously Verified Algorithms. The process relies on formal methods for rigorously validating code against its requirements. The software development process uses: (1) a formal specification language for describing the algorithms and their functional requirements, (2) an interactive theorem prover for formally verifying the correctness of the algorithms, (3) test cases that stress the code, and (4) numerical evaluation on these test cases of both the algorithm specifications and their implementations in code. The MINERVA process is illustrated in this paper with an application to geo-containment algorithms for unmanned aircraft systems. These algorithms ensure that the position of an aircraft never leaves a predetermined polygon region and provide recovery maneuvers when the region is inadvertently exited.

  2. DATABASES DEVELOPED IN INDIA FOR BIOLOGICAL SCIENCES

    Full Text Available The complexity of biological systems requires use of a variety of experimental methods with ever increasing sophistication to probe various cellular processes at molecular and atomic resolution. The availability of technologies for determining nucleic acid sequences of genes and atomic resolution structures of biomolecules prompted development of major biological databases like GenBank and PDB almost four decades ago. India was one of the few countries to realize early, the utility of such databases for progress in modern biology/biotechnology. Department of Biotechnology (DBT, India established Biotechnology Information System (BTIS network in late eighties. Starting with the genome sequencing revolution at the turn of the century, application of high-throughput sequencing technologies in biology and medicine for analysis of genomes, transcriptomes, epigenomes and microbiomes have generated massive volumes of sequence data. BTIS network has not only provided state of the art computational infrastructure to research institutes and universities for utilizing various biological databases developed abroad in their research, it has also actively promoted research and development (R&D projects in Bioinformatics to develop a variety of biological databases in diverse areas. It is encouraging to note that, a large number of biological databases or data driven software tools developed in India, have been published in leading peer reviewed international journals like Nucleic Acids Research, Bioinformatics, Database, BMC, PLoS and NPG series publication. Some of these databases are not only unique, they are also highly accessed as reflected in number of citations. Apart from databases developed by individual research groups, BTIS has initiated consortium projects to develop major India centric databases on Mycobacterium tuberculosis, Rice and Mango, which can potentially have practical applications in health and agriculture.

Some of the issues result from the difficulty and complexity of the technological issues; others have programmatic bases, such as strategies that may provide undue focus on near-term goals or difficulty in developing and maintaining stakeholder confidence in the proposed solutions. We propose that independent basic fundamental science research, addressing the full cleanup life-cycle, offers an opportunity to help address these challenges by providing (1) scientific insight into the fundamental mechanisms involved in currently selected processing and disposal options, (2) a rational path to the development of alternative technologies should the primary options fail, (3) confidence that models that predict long-term performance of different disposal options are based upon the best available science, and (4) fundamental science discovery that enables transformational solutions to revolutionize the current baseline processes. Over the last 3 years, DOE's Office of Environmental Management (EM) has experienced a fundamental shift in philosophy. The mission focus of driving to closure has been replaced by one of enabling the long-term needs of DOE and the nation. Resolving new challenges, such as the disposition of DOE spent nuclear fuel, have been added to EM's responsibilities. In addition, the schedules for addressing several elements of the cleanup mission have been extended. As a result, EM's mission is no longer focused only on driving the current baselines to closure. Meeting the mission will require fundamental advances over at least a 30-year window if not longer as new challenges are added. The

    The purposes of this study were (1) to develop a science and technology (ST) ethics education program for prospective science teachers, (2) to examine the effect of the program on the perceptions of the participants, in terms of their ethics and education concerns, and (3) to evaluate the impact of the program design. The program utilized problem-based learning (PBL) which was performed as an iterative process during two cycles. A total of 23 and 29 prospective teachers in each cycle performed team activities. A PBL-based ST ethics education program for the science classroom setting was effective in enhancing participants' perceptions of ethics and education in ST. These perceptions motivated prospective science teachers to develop and implement ST ethics education in their future classrooms. The change in the prospective teachers' perceptions of ethical issues and the need for ethics education was greater when the topic was controversial.

  13. The typology and development of attitude to primary science education

    Science.gov (United States)

    Gray, Adelaide

    The introduction and development of science within the primary curriculum has been a challenge to teachers, parents and children and a highly politicised decision. Augmenting any difficulties are the images of science within popular culture and the traditions of scientific inquiry that have maintained the Western, male elitist hierarchy of the Vienna circle throughout the last millennium. The Royal Society's committee on the public understanding of science has recognised the difficulty in recruiting students to higher-level science study and embarked on a programme of sponsorship to address this. At the same time major governmental policy changes have provided a new 'market' model of education that has encouraged parental involvement in schools and enforced a new 'transparency' of evaluation on schools through league tables and Ofsted. Set against this backdrop, this research explores the development of attitudes to science and science education in the parent's of primary school aged children. It examines the perceptions of science and science education through the narrative of the parent's and their understanding of the interaction between different areas of science. The use of key events within narrative as a method of exploring attitude and conceptual development is novel to this research and through this exploration the concept of attitude itself is examined and criticised developing a new concept of attitude as process-based rather than static or crystallised. This reconceptualisation allows a more operational understanding of attitude that overcomes the difficulties of the traditional concept, which has only a limited theoretical basis on which to examine behaviour. The research generates a typology for views of science and the more operational compliment to this, stance to science. This framework allows a greater understanding of attitude formation, how science is perceived and how this perception is actualised. It is particularly interesting given the

    Full Text Available Twenty-three pre-collegiate educators of elementary students (ages 5-10 years and secondary students (ages 11-18 years attended a two-week science, technology, engineering, and mathematics (STEM astronomy focused professional development in the summer of 2015 with activities focused on authentic science experiences, inquiry, and partnership building. ‘Authentic’ in this research refers to scientific skills and are defined. The study explores the authentic science education experience of the pre-collegiate educators, detailing the components of authentic science as seen through a social constructionism lens. Using qualitative and quantitative methods, the researchers analyzed the successes and challenges of pre-collegiate science and mathematics educators when immersed in STEM and astronomy authentic science practices, the educators’ perceptions before and after the authentic science practices, and the educators’ performance on pre to post content tests during the authentic science practices. Findings show that the educators were initially engaged, then disengaged, and then finally re-engaged with the authentic experience. Qualitative responses are shared, as are the significant results of the quantitative pre to post content learning scores of the educators. Conclusions include the necessity for PD team delivery of detailed explanations to the participants - before, during, and after – for the entire authentic science experience and partnership building processes. Furthermore, expert structure and support is vital for participant research question generation, data collection, and data analysis (successes, failures, and reattempts. Overall, in order to include authentic science in pre-collegiate classrooms, elementary and secondary educators need experience, instruction, scaffolding, and continued support with the STEM processes.

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

    This study aimed to discuss how caring science can contribute and provide a theoretical foundation for the development of caring within forensic psychiatric care. It is not only a challenge but also a great opportunity to use caring science theory within forensic psychiatric care when caring for the patients and supporting their health processes. There is a need for more knowledge about, understanding of, and willingness to care for patients within forensic psychiatric settings in a "true caring" way. In order to achieve this, a caring culture is required, one that supports carers and provides them with opportunities to further develop a caring attitude. © 2014 Wiley Periodicals, Inc.

    Objective was to examine the creative process, demonstrated by 5 student participants in a class at the Art Center College of Design in Pasadena CA, from the germ of the creative idea through the final creative product. The students, drawn from classes sponsored by LLNL, were assigned the problem of representing ``big`` science, as practiced at LLNL, in a graphic, artistic, or multimedia product. As a result of this study, it was discovered that the process of creativity with these students was not linear in nature, nor did it strictly follow the traditional creativity 5-step schema of preparation, incubation, insight, evaluation, and elaboration. Of particular interest were several emergent themes of the creative process: spontaneous use of metaphor to describe the Laboratory; a general lack of interest in ``school`` science or mathematics by the American art students; a well developed sense of conscience; and finally, the symbolism inherent in the repeated use of a single artistic element. This use of the circle revealed a continuity of thinking and design perhaps related to the idealistic bias mentioned above.

    better performance than the local machine. Much of the difference was due to newer equipment in the Nebula than the legacy computer, which is suggestive of a potential economic advantage beyond elastic power, i.e., access to up-to-date hardware vs. legacy hardware that must be maintained past its prime to amortize the cost. In addition to a trade study of advantages and challenges of porting complex processing to the cloud, a tutorial was developed to enable further progress in utilizing the Nebula for Earth Science applications and understanding better the potential for Cloud Computing in further data- and computing-intensive Earth Science research. In particular, highly bursty computing such as that experienced in the user-demand-driven Giovanni system may become more tractable in a Cloud environment. Our future work will continue to focus on migrating more GES DISC's applications/instances, e.g. Giovanni instances, to the Nebula platform and making matured migrated applications to be in operation on the Nebula.

    Full Text Available Background due to defining the role of people in the development of society and the almost complete absence of scientific management processes capable of progressive development of both individuals and social communities, and nations, and civilization in general. In order to overcome inherent subjectivist methodology of knowledge, psyholohizatorskyh, hiperpolityzovanyh and utilitarian approach, the authors proposed a three-tier system of business processes of society. The conceptual core of the approach consists in the detection task as logical - mathematical laws of subjects of primary, secondary and higher levels of development, and on the mechanisms of their formation and practice. The solution of the tasks allowed the authors to reveal the structure of both the ascending and descending processes of economic society. Thus, the analysis of individual carriers upward changes as «individual», «individuality», «person» and «personality» showed conditionality determination of their activities with «anthropometric», «ethnic», «demographic» and «ideological» mechanisms. Nature as common carriers downstream changes revealed using correlative related «groups», «group «, «groups» and «communities» whose activity is due to «vitalistic», «education», «professional» and «stratification» mechanisms. To disclose the nature and organization of secondary and higher levels of economic society by the authors introduced the category of «citizen», «heneralista», «human space», «human galactic» ‘formation and development is causing «status», «Persona logical», «humanocentric», «institutional», «cluster», «kontaminatsiyni» and other mechanisms. One of the main achievements of the work, the authors consider the possibility of further development and practical implementation of new quality management processes of economic society based multimodal dialectical logic.

    Cognitive science has become the most influential paradigm on mental health in the late 20(th) and the early 21(st) centuries. In few years, the concepts, problem approaches and solutions proper to this science have significantly changed. Introduction and discussion of the fundamental concepts of cognitive science divided in four stages: Start, Classic Cognitivism, Connectionism, and Embodying / Enacting. The 2(nd) Part of the paper discusses the above mentioned fourth stage and explores the clinical setting, especially in terms of cognitive psychotherapy. The embodying/enacting stage highlights the role of the body including a set of determined evolutionary movements which provide a way of thinking and exploring the world. The performance of cognitive tasks is considered as a process that uses environmental resources that enhances mental skills and deploys them beyond the domestic sphere of the brain. On the other hand, body and mind are embedded in the world, thus giving rise to cognition when interacting, a process known as enacting. There is a close connection between perception and action, hence the interest in real-time interactions with the world rather than abstract reasoning. Regarding clinics, specifically the cognitive therapy, there is little conceptual discussion maybe due to good results from practice that may led us to consider that theoretical foundations are firm and not problem-raising.

    Cerdeira, Hilda; Fonda, Carlo; Cottrell, R L A

    2003-01-01

    Enabling scientists from developing countries to bridge the gap between rich and poor depends on closing another gap - the "digital divide". Now the technology exists to monitor this divide, and it reveals some alarming results. Most developing countries experience great difficulties because of adverse economic conditions and political instability, which means they lag behind in scientific and technological development. With the advent of the World Wide Web and the rapid exchange of information via the Internet, one might naively have thought that much of the gap between developed and developing nations would disappear, even if problems still persisted for those areas of science that need expensive facilities. However, access to information, peer reviewed or not, depends on having the appropriate hardware, i.e. a computer, and Internet connectivity, and there is a serious problem with access to the Internet in developing countries. Gaining access to a computer is more of a question of economics, and one that ...

    To show that nutrition science is anchored in food systems and is influenced by the social, through the environmental to the cosmological, life's connections and rhythms. To indicate that an integrative approach is now becoming possible with advances in food technology, in the understanding of food choice and of human behaviour, and in a preparedness to recognise nutritional inputs in the full sweep of life-long well-being and health outcomes. An analysis of the much broader understanding of nutritionally related diseases from an ecological perspective, with attention to economic development, beginning with poverty alleviation. Recognition that the biological dimension of nutrition science is undergoing a profound reappraisal; that technologies will allow us to change the course of nutritionally related diseases for the better; and that nutrition science will find partners in information technology and telecommunications, food technology and energy technology. A new generation of nutrition scientists can help build a new economy that supports development amongst communities, whether close or distant from each other. The opportunities for this kind of development to be realised between Asia, Latin America and Africa are considerable. At all times, however, nutrition scientists must uphold the paramount importance of good governance, conflict resolution and maternal literacy if their work is to achieve its growing potential.

    Grady, Colleen Marie

    2016-07-04

    Purpose The purpose of this paper is to describe research that examined physician leadership development using complexity science principles. Design/methodology/approach Intensive interviewing of 21 participants and document review provided data regarding physician leadership development in health-care organizations using five principles of complexity science (connectivity, interdependence, feedback, exploration-of-the-space-of-possibilities and co-evolution), which were grouped in three areas of inquiry (relationships between agents, patterns of behaviour and enabling functions). Findings Physician leaders are viewed as critical in the transformation of healthcare and in improving patient outcomes, and yet significant challenges exist that limit their development. Leadership in health care continues to be associated with traditional, linear models, which are incongruent with the behaviour of a complex system, such as health care. Physician leadership development remains a low priority for most health-care organizations, although physicians admit to being limited in their capacity to lead. This research was based on five principles of complexity science and used grounded theory methodology to understand how the behaviours of a complex system can provide data regarding leadership development for physicians. The study demonstrated that there is a strong association between physician leadership and patient outcomes and that organizations play a primary role in supporting the development of physician leaders. Findings indicate that a physician's relationship with their patient and their capacity for innovation can be extended as catalytic behaviours in a complex system. The findings also identified limiting factors that impact physicians who choose to lead, such as reimbursement models that do not place value on leadership and medical education that provides minimal opportunity for leadership skill development. Practical Implications This research provides practical

  17. 21st Century Science as a Relational Process: From Eureka! to Team Science and a Place for Community Psychology

    Science.gov (United States)

    Tebes, Jacob Kraemer; Thai, Nghi D.; Matlin, Samantha L.

    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.

  18. Professional development in college science teaching

    Science.gov (United States)

    Thomas, Aimee Kathryn

    Graduate students earning a doctorate in the sciences historically focus their work on research and not professional development in college science teaching. However, for those who go on to a career in academia, a majority of their time will be dedicated to teaching. During the past few years, graduate teaching assistants (GTAs) have been prepared to teach by attending a daylong workshop that included logistical information, but left pedagogy largely unexplored. Since that time, a seminar has been added to provide an introduction to pedagogical theory and practices and to provide practice teaching in the biological sciences laboratory course. Yet, more pedagogical preparation is needed. This study was conducted to determine if there was a need for a teaching certificate program for doctoral students in the College of Science and Technology (CoST) at The University of Southern Mississippi. The GTA respondents studied set teaching goals that were consistent with faculty members across the country; however, this research went further by finding out how competent the GTAs perceived they were and how much support they perceived they needed with respect to teaching and professional development. The GTAs did not differ in their perceived level of competence based on experience level; however, the less experienced GTAs did perceive they needed more support than the experienced GTAs. To help GTAs develop a skill set that many CoST graduates currently lack, it is recommended that the University provide ample training and supervision. Establishing a certificate program can potentially impact the community in the following ways: (1) the training of GTAs contributes to the academic preparation of future academic professionals who will be teaching in various institutions; (2) GTA training provides professional development and awareness that teaching requires life long professional development; (3) ensuring competent academicians, not only in content but also in pedagogy; (4

    José Manuel do Carmo

    2016-12-01

    Full Text Available The basic vision of learning science has changed as scientific culture concepts evolution and the nature of the teaching of science go along. From a model essentially based on information acquisition, science instruction has included the practice of the science method when the importance of emphasizing the development of personal skills, thinking processes, and action was considered. The concern about citizens’ education in matters referring to the relationship between science and society and enlightened social participation demanded a special attention in investigation and in students’ participation in issues related to urban, natural, and technological environment. This research seeks to develop an integrative model of curriculum organizations based on these three axes or perspectives: science, individual, and society. A matrix enabling the analysis of curricular proposals and organization plans of didactic units is built, as well as the observation of teachers’ representations in the teaching of science.

  1. Emphasizing the process of science using demonstrations in conceptual chemistry

    Science.gov (United States)

    Lutz, Courtney A.

    The purpose of this project was to teach students a method for employing the process of science in a conceptual chemistry classroom when observing a demonstration of a discrepant event. Students observed six demonstrations throughout a trimester study of chemistry and responded to each demonstration by asking as many questions as they could think of, choosing one testable question to answer by making as many hypotheses as possible, and choosing one hypothesis to make predictions about observed results of this hypothesis when tested. Students were evaluated on their curiosity, confidence, knowledge of the process of science, and knowledge of the nature of science before and after the six demonstrations. Many students showed improvement in using or mastery of the process of science within the context of conceptual chemistry after six intensive experiences with it. Results of the study also showed students gained confidence in their scientific abilities after completing one trimester of conceptual chemistry. Curiosity and knowledge of the nature of science did not show statistically significant improvement according to the assessment tool. This may have been due to the scope of the demonstration and response activities, which focused on the process of science methodology instead of knowledge of the nature of science or the constraints of the assessment tool.

    For the breast cancer diagnosis and therapy, a prototype of positron emission mammography (PEM) was developed in Institute of High Energy Physics, Chinese Academy of Sciences. In this paper, the design of coincidence processing module (CPM) for this PEM was presented. Both the hardware architecture and the software logic were introduced. In this design, the CPM used the Rocket IO fast interface in FPGA and fiber technology to acquire the preprocessed data from the continuous sampling module (CSM) and then selected the valid event with the coincidence timing window method, which was performed in the FPGA on the daughter board. The CPM transmits the processed data to host computer via gigabit Ethernet. The whole system was controlled by CAN bus. The primary tests indicate that the performance of this design is good.

    Cleaning up the nation's nuclear weapons complex remains as one of the most technologically challenging and financially costly problems facing the U.S. Department of Energy (DOE). Safety, cost, and technological challenges have often delayed progress in retrieval, processing, and final disposition of high-level waste, spent nuclear fuel, and challenging materials. Some of the issues result from the difficulty and complexity of the technological issues; others have programmatic bases, such as strategies that may provide undue focus on near-term goals or difficulty in developing and maintaining stakeholder confidence in the proposed solutions. We propose that independent basic fundamental science research addressing the full cleanup life-cycle offers an opportunity to help address these challenges by providing 1) scientific insight into the fundamental mechanisms involved in currently selected processing and disposal options, 2) a rational path to the development of alternative technologies should the primary options fail, 3) confidence that models that predict long-term performance of different disposal options are based upon the best available science, and 4) fundamental science discovery that enables transformational solutions to revolutionize the current baseline processes. Over the last 3 years, DoE's Office of Environmental Management (EM) has experienced a fundamental shift in philosophy. The mission focus of driving to closure has been replaced by one of enabling the long-term needs of DOE and the nation. Resolving new challenges, such as the disposition of DOE spent nuclear fuel, have been added to EM's responsibilities. In addition, the schedules for addressing several elements of the cleanup mission have been extended. As a result, EM's mission is no longer focused only on driving the current baselines to closure. Meeting the mission will require fundamental advances over at least a 30-year window if not longer as new challenges are added. The overall

    Elam, Jeffrey W.

    2015-01-01

    Photovoltaic manufacturing is an emerging industry that promises a carbon-free, nearly limitless source of energy for our nation. However, the high-temperature manufacturing processes used for conventional silicon-based photovoltaics are extremely energy-intensive and expensive. This high cost imposes a critical barrier to the widespread implementation of photovoltaic technology. Argonne National Laboratory and its partners recently invented new methods for manufacturing nanostructured photovoltaic devices that allow dramatic savings in materials, process energy, and cost. These methods are based on atomic layer deposition, a thin film synthesis technique that has been commercialized for the mass production of semiconductor microelectronics. The goal of this project was to develop these low-cost fabrication methods for the high efficiency production of nanostructured photovoltaics, and to demonstrate these methods in solar cell manufacturing. We achieved this goal in two ways: 1) we demonstrated the benefits of these coatings in the laboratory by scaling-up the fabrication of low-cost dye sensitized solar cells; 2) we used our coating technology to reduce the manufacturing cost of solar cells under development by our industrial partners.

    Objective was to follow the cognitive and creative processes demonstrated by student research participants as they integrated a developing knowledge of ``big`` science, as practiced at LLNL, into a personal and idiosyncratic visual, graphical, or multimedia product. The participants, all non-scientists, involved in this process, attended a series of design classes, sponsored by LLNL at the Art Center College of Design in Pasadena CA. As a result of this study, we have become interested in the possibility of similar characteristics between scientists and artists. We have also become interested in the different processes that can be used to teach science to non-scientists, so that they are able to understand and portray scientific information.

    2007-01-01

    NASA has impaneled several internal working groups to provide recommendations to NASA management on ways to evolve and improve Earth Science Data Systems. One of these working groups is the Standards Process Group (SPC). The SPG is drawn from NASA-funded Earth Science Data Systems stakeholders, and it directs a process of community review and evaluation of proposed NASA standards. The working group's goal is to promote interoperability and interuse of NASA Earth Science data through broader use of standards that have proven implementation and operational benefit to NASA Earth science by facilitating the NASA management endorsement of proposed standards. The SPC now has two years of experience with this approach to identification of standards. We will discuss real examples of the different types of candidate standards that have been proposed to NASA's Standards Process Group such as OPeNDAP's Data Access Protocol, the Hierarchical Data Format, and Open Geospatial Consortium's Web Map Server. Each of the three types of proposals requires a different sort of criteria for understanding the broad concepts of "proven implementation" and "operational benefit" in the context of NASA Earth Science data systems. We will discuss how our Standards Process has evolved with our experiences with the three candidate standards.

    2015-08-01

    In the frame of the Europlanet-RI program, a prototype Virtual Observatory dedicated to Planetary Science has been set up. Most of the activity was dedicated to the definition of standards to handle data in this field. The aim was to facilitate searches in big archives as well as sparse databases, to make on-line data access and visualization possible, and to allow small data providers to make their data available in an interoperable environment with minimum effort. This system makes intensive use of studies and developments led in Astronomy (IVOA), Solar Science (HELIO), and space archive services (IPDA).The current architecture connects existing data services with IVOA or IPDA protocols whenever relevant. However, a more general standard has been devised to handle the specific complexity of Planetary Science, e.g. in terms of measurement types and coordinate frames. This protocol, named EPN-TAP, is based on TAP and includes precise requirements to describe the contents of a data service (Erard et al Astron & Comp 2014). A light framework (DaCHS/GAVO) and a procedure have been identified to install small data services, and several hands-on sessions have been organized already. The data services are declared in standard IVOA registries. Support to new data services in Europe will be provided during the proposed Europlanet H2020 program, with a focus on planetary mission support (Rosetta, Cassini…).A specific client (VESPA) has been developed at VO-Paris (http://vespa.obspm.fr). It is able to use all the mandatory parameters in EPN-TAP, plus extra parameters from individual services. A resolver for target names is also available. Selected data can be sent to VO visualization tools such as TOPCAT or Aladin though the SAMP protocol.Future steps will include the development of a connection between the VO world and GIS tools, and integration of heliophysics, planetary plasma and reference spectroscopic data.The EuroPlaNet-RI project was funded by the European

    2018-01-01

    As the second largest pharmaceutical market with a great potential for future growth, China has drawn much attention from the global pharmaceutical community. With an increasing government investment in biomedical research, the domestic biopharmaceutical (biotechnological) companies in China are turning their attention to the development of innovative medicines and targeting the global market. To introduce innovative products to Chinese patients sooner, to improve the efficiency of its review and approval processes, and to harmonize its regulatory science with international standards, the China Food and Drug Administration (CFDA) has initiated a series of major changes to its policies and regulations. This paper presents a snapshot of China's pharmaceutical market, and research and development status, and introduces technical guidelines pertaining to clinical trials and new drug applications. The recent wave of ground-breaking reforms in CFDA's regulatory science is discussed. Examples of clinical trials and new drug applications are provided throughout the discussion.

    2012-04-01

    Using various neutron scattering, imaging, and activation analysis instruments and irradiation facility and capsules, the short-term industrial application and mid and long-term basic science with neutrons was carried out. In this regard, we proposed the utilization of the neutron scattering and diffraction techniques to the study of physical, mechanical material properties in industrial components. The nano magnetic thin film structure study using neutron reflectometry, spin structure and dynamics study using neutron scattering, hydrogen combination structure study using single crystal diffraction were carried out. The triple-axis spectrometer has been installed. Also, a new growth facility of single crystal has been developed to supply crystals for the neutron scattering experiment. We have contributed to the performance enhancement of hydrogen fuel cell by the development of quantitative neutron radiography technology and developed the differential phase imaging technology using silicon grating. To perform precise neutron activation analysis, a Compton suppressed gamma-ray spectroscopy system was installed. Through the analysis of actual samples as well as geological and biological reference materials, performance test was carried out. We built up analytical data base and develope integrated analytical program for INAA/PGAA. The analysis and evaluation technology of the irradiation capsule test in HANARO for the commercial and future nuclear reactor systems was improved

  1. Science and technology in a developing country: The Brazilian case

    International Nuclear Information System (INIS)

    Vargas, Jose Israel

    2001-01-01

    Full text: This paper treats the development of science and technology in Brazil in a historical perspective within the Brazilian socio-economic context. The development of natural and human resources and the buildup of the Brazilian economy that have taken place over the last few decades are best described against the background of the well known economic cycles involving sugar production, gold mining and coffee cultivation, all largely based on slave labor until late in the 19th century. Brazilian industrialization has often been described as resulting from the adoption of an import substitution model. This paper claims that, alternatively, it may be described as a technology importation model. The implementation of this scheme demanded the rapid development of human capital which, in Brazil, has followed an original approach. In fact, traditional university education only started in the 1930s, higher education having taken root only in previously isolated high quality technical schools, such as mining, electrical engineering, agricultural engineering and, of course, the traditional institutions for teaching medicine and law. By the 1950s, largely under the influence of some outstanding scientists - mostly trained in the frontiers of nuclear sciences - the National Council of Research and the National Post-Graduate Training Programme were created. This has led, until now, to reasonable scientific, and to a lesser extent, technological development. The recent globalization process - the new economy - has broken down barriers to international commerce and required in recent years greater efforts to disseminate basic general education and the fostering of advanced science and technology. To this end, science and technology, along with research and development activities, have reached 1.35% and 0.9% of Brazil's GNP, respectively. Innovation as measured by patent applications has been modest. However, the technology balance has grown since the 1990s at a rate greater

    2016-07-01

    The purpose of the Observatory Software System (OSW) is to integrate all software and hardware components of the Thirty Meter Telescope (TMT) to enable observations and data capture; thus it is a complex software system that is defined by four principal software subsystems: Common Software (CSW), Executive Software (ESW), Data Management System (DMS) and Science Operations Support System (SOSS), all of which have interdependencies with the observatory control systems and data acquisition systems. Therefore, the software development process and plan must consider dependencies to other subsystems, manage architecture, interfaces and design, manage software scope and complexity, and standardize and optimize use of resources and tools. Additionally, the TMT Observatory Software will largely be developed in India through TMT's workshare relationship with the India TMT Coordination Centre (ITCC) and use of Indian software industry vendors, which adds complexity and challenges to the software development process, communication and coordination of activities and priorities as well as measuring performance and managing quality and risk. The software project management challenge for the TMT OSW is thus a multi-faceted technical, managerial, communications and interpersonal relations challenge. The approach TMT is using to manage this multifaceted challenge is a combination of establishing an effective geographically distributed software team (Integrated Product Team) with strong project management and technical leadership provided by the TMT Project Office (PO) and the ITCC partner to manage plans, process, performance, risk and quality, and to facilitate effective communications; establishing an effective cross-functional software management team composed of stakeholders, OSW leadership and ITCC leadership to manage dependencies and software release plans, technical complexities and change to approved interfaces, architecture, design and tool set, and to facilitate

  15. Knowledge acquisition process as an issue in information sciences

    Directory of Open Access Journals (Sweden)

    Boris Bosančić

    2016-07-01

    Full Text Available The paper presents an overview of some problems of information science which are explicitly portrayed in literature. It covers the following issues: information explosion, information flood and data deluge, information retrieval and relevance of information, and finally, the problem of scientific communication. The purpose of this paper is to explain why knowledge acquisition, can be considered as an issue in information sciences. The existing theoretical foundation within the information sciences, i.e. the DIKW hierarchy and its key concepts - data, information, knowledge and wisdom, is recognized as a symbolic representation as well as the theoretical foundation of the knowledge acquisition process. Moreover, it seems that the relationship between the DIKW hierarchy and the knowledge acquisition process is essential for a stronger foundation of information sciences in the 'body' of the overall human knowledge. In addition, the history of both the human and machine knowledge acquisition has been considered, as well as a proposal that the DIKW hierarchy take place as a symbol of general knowledge acquisition process, which could equally relate to both human and machine knowledge acquisition. To achieve this goal, it is necessary to modify the existing concept of the DIKW hierarchy. The appropriate modification of the DIKW hierarchy (one of which is presented in this paper could result in a much more solid theoretical foundation of the knowledge acquisition process and information sciences as a whole. The theoretical assumptions on which the knowledge acquisition process may be established as a problem of information science are presented at the end of the paper. The knowledge acquisition process does not necessarily have to be the subject of epistemology. It may establish a stronger link between the concepts of data and knowledge; furthermore, it can be used in the context of scientific research, but on the more primitive level than conducting

    The mass extinction event at the Cretaceous-Paleogene (K-Pg) boundary was the result of a bolide impact, and is popularly known for the extinction of the dinosaurs, but is also one of the largest Paleogene mass extinctions identified. In addition, it was followed by a period of drastic changes in ecological conditions, including a complete alteration of the global carbon cycle; the root cause of this change is still debated. Little information is known regarding changes in the nitrogen cycle during these periods of mass extinction and recovery. Given the importance of the nitrogen cycle to primary production and its relationship to the redox state of the local environment, determining changes in the nitrogen cycle will provide important information as to the processes of global mass extinction and the subsequent recovery. Three lessons for students' grade 6-12 were created to support the content surrounding: National Science Education Content Standards: Standard A: Science as Inquiry Standard D: Earth and Space Science Ocean Literacy Essential Principles: 3. The ocean is a major influence on weather and climate 7. The ocean is largely unexplored In the Nature of Science activity, students sequence a series of photographs to illustrate the scientific process of one scientist, Dr. Tracy Quan, of Oklahoma State University as she uses deep sea core data obtained by the JOIDES Resolution research vessel to investigate the climate during the mass extinction that took place ~ 65 million years ago. By reading the information contained on each card and studying the pictures, students learn that science is a dynamic, non-linear, and creative process. Students do not have to create the exact order Dr. Quan uses as her scientific process, but they need to justify their reasoning for placing the pictures in the order they did. The activity begins with a photo of the JOIDES Resolution and ends during a presentation at a scientific conference. There are 21 other photo cards

    This report is a summary of the work completed in FY01 for science-based characterization of the processes used to fabricate 1) cermet vias in source feedthrus using slurry and paste-filling techniques and 2) cermet powder for dry pressing. Common defects found in cermet vias were characterized based on the ability of subsequent processing techniques (isopressing and firing) to remove the defects. Non-aqueous spray drying and mist granulation techniques were explored as alternative methods of creating CND50, the powder commonly used for dry pressed parts. Compaction and flow characteristics of these techniques were analyzed and compared to standard dry-ball-milled CND50. Due to processing changes, changes in microstructure can occur. A microstructure characterization technique was developed to numerically describe cermet microstructure. Machining and electrical properties of dry pressed parts were also analyzed and related to microstructure using this analytical technique.3 Executive SummaryThis report outlines accomplishments in the science-based understanding of cermet processing up to fiscal year 2002 for Sandia National Laboratories. The three main areas of work are centered on 1) increasing production yields of slurry-filled cermets, 2) evaluating the viability of high-solids-loading pastes for the same cermet components, and 3) optimizing cermet powder used in pressing processes (CND50). An additional development that was created as a result of the effort to fully understand the impacts of alternative processing techniques is the use of analytical methods to relate microstructure to physical properties. Recommendations are suggested at the end of this report. Summaries of these four efforts are as follows:1.Increase Production Yields of Slurry-Filled Cermet Vias Finalized slurry filling criteria were determined based on three designs of experiments where the following factors were analyzed: vacuum time, solids loading, pressure drop across the filter paper

  1. Evaluating a Graduate Professional Development Program for Informal Science Educators

    Lake, Jeremy Paul

    This study is an examination and evaluation of the outcomes of a series of courses that I helped build to create a graduate certificate. Specifically, I wanted to evaluate whether or not the online iteration of the Informal Science Institutions Environmental Education Graduate Certificate Program truly provided the long term professional development needed to enhance the skills of the formal and informal educators participating so that they could contribute meaningfully to the improvement of science literacy in their respective communities. My role as an internal evaluator provided an extraordinary opportunity to know the intent of the learning opportunities and why they were constructed in a particular fashion. Through the combination of my skills, personal experiences both within the certificate's predecessor and as an educator, I was uniquely qualified to explore the outcomes of this program and evaluate its effectiveness in providing a long-term professional development for participants. After conducting a literature review that emphasized a need for greater scientific literacy in communities across America, it was evident that the formal education enterprise needs the support of informal educators working on the ground in myriad different settings in ways that provide science as both content and process, learning science facts and doing real science. Through a bridging of informal science educators with formal teachers, it was thought each could learn the culture of the other, making each more fluent in accessing community resources to help make these educators more collaborative and able to bridge the classroom with the outside world. This bridge promotes ongoing, lifelong learning, which in turn can help the national goal of greater scientific literacy. This study provided insight into the thinking involved in the learners' growth as they converted theory presented in course materials into practice. Through an iterative process of reviewing the course

    Peterson, James K

    2016-01-01

    This book shows how mathematics, computer science and science can be usefully and seamlessly intertwined. It begins with a general model of cognitive processes in a network of computational nodes, such as neurons, using a variety of tools from mathematics, computational science and neurobiology. It then moves on to solve the diffusion model from a low-level random walk point of view. It also demonstrates how this idea can be used in a new approach to solving the cable equation, in order to better understand the neural computation approximations. It introduces specialized data for emotional content, which allows a brain model to be built using MatLab tools, and also highlights a simple model of cognitive dysfunction.

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

    Full Text Available Biohybrid consists of a living organism or cell and at least one engineered component. Designing robot–plant biohybrids is a great challenge: it requires interdisciplinary reconsideration of capabilities intimate specific to the biology of plants. Envisioned advances should improve agricultural/horticultural/social practice and could open new directions in utilization of plants by humans. Proper biohybrid cooperation depends upon effective communication. During evolution, plants developed many ways to communicate with each other, with animals, and with microorganisms. The most notable examples are: the use of phytohormones, rapid long-distance signaling, gravity, and light perception. These processes can now be intentionally re-shaped to establish plant–robot communication. In this article, we focus on plants physiological and molecular processes that could be used in bio-hybrids. We show phototropism and biomechanics as promising ways of effective communication, resulting in an alteration in plant architecture, and discuss the specifics of plants anatomy, physiology and development with regards to the bio-hybrids. Moreover, we discuss ways how robots could influence plants growth and development and present aims, ideas, and realized projects of plant–robot biohybrids.

    Munk, Michelle M.

    2006-01-01

    Within NASA's Science Mission Directorate is a technological program dedicated to improving the cost, mass, and trip time of future scientific missions throughout the Solar System. The In-Space Propulsion Technology (ISPT) Program, established in 2001, is charged with advancing propulsion systems used in space from Technology Readiness Level (TRL) 3 to TRL6, and with planning activities leading to flight readiness. The program's content has changed considerably since inception, as the program has refocused its priorities. One of the technologies that has remained in the ISPT portfolio through these changes is Aerocapture. Aerocapture is the use of a planetary body's atmosphere to slow a vehicle from hyperbolic velocity to a low-energy orbit suitable for science. Prospective use of this technology has repeatedly shown huge mass savings for missions of interest in planetary exploration, at Titan, Neptune, Venus, and Mars. With launch vehicle costs rising, these savings could be the key to mission viability. This paper provides an update on the current state of the Aerocapture technology development effort, summarizes some recent key findings, and highlights hardware developments that are ready for application to Aerocapture vehicles and entry probes alike. Description of Investments: The Aerocapture technology area within the ISPT program has utilized the expertise around NASA to perform Phase A-level studies of future missions, to identify technology gaps that need to be filled to achieve flight readiness. A 2002 study of the Titan Explorer mission concept showed that the combination of Aerocapture and a Solar Electric Propulsion system could deliver a lander and orbiter to Titan in half the time and on a smaller, less expensive launch vehicle, compared to a mission using chemical propulsion for the interplanetary injection and orbit insertion. The study also identified no component technology breakthroughs necessary to implement Aerocapture on such a mission

    2018-01-01

    A training program was developed for enhancing pre-service science teachers' pedagogical content knowledge (PCK). The pre-service science teachers are able to: understand science curriculum, knowledge of assessment in science, knowledge of students' understanding of science, instructional strategies and orientations towards science teaching, which is conceptualized as PCK [5]. This study examined the preservice science teachers' understandings and their practices which include five pre-service science teachers' PCK. In this study, the participants demonstrated their PCK through the process of the training program by writing content representations (CoRes), preparing the lesson plans, micro-teaching, and actual teaching respectively. All pre-service science teachers' performs were collected by classroom observations. Then, they were interviewed. The results showed that the pre-service science teachers progressively developed knowledge components of PCK. Micro-teaching is the key activities for developing PCK. However, they had some difficulties in their classroom teaching. They required of sufficient ability to design appropriate instructional strategies and assessment activities for teaching. Blending content and pedagogy is also a matter of great concern. The implication of this study was that science educators can enhance pre-service science teachers' PCK by fostering their better understandings of the instructional strategies, assessment activities and blending between content and pedagogy in their classroom.

    The current grant is a continuation of a previous grant awarded to the Institute for Regulatory Science. In July, 1989, the functions of the Institute were transferred to the University of Maryland and the studies started at the Institute were continued at the University. The current grant started February 1, 1990. Therefore, much of the discussion in this progress report relies upon the grant funded at the Institute for Regulatory Science. This progress report covers the period from February 1, 1990 to January 31, 1991. The objective of the project is to assure that societal decisions are based on the best available science (BAS). A great deal of progress was made to establish relevant organizations for the development of consensus on relevant scientific information. During the next year, emphasis will be placed on Resource Conservation and Recovery Act (RCRA), particularly as related to its reauthorization and mixed waste

    Since its inception three years ago, the Land Processes Aircraft Science Management Operations Working Group (MOWG) provided recommendations on the optimal use of the Agency's aircraft in support of the Land Processes Science Program. Recommendations covered topics such as aircraft and sensor usage, development of long-range plans, Multisensor Airborne Campaigns (MAC), program balance, aircraft sensor databases, new technology and sensor development, and increased University scientist participation in the program. Impacts of these recommendations improved the efficiency of various procedures including the flight request process, tracking of flight hours, and aircraft usage. The group also created a bibliography focused on publications produced by Land Processes scientists from the use of the aircraft program, surveyed NASA funded PI's on their participation in the aircraft program, and developed a planning template for multi-sensor airborne campaigns. Benefits from these activities are summarized.

  20. Toward an Analytic Framework of Interdisciplinary Reasoning and Communication (IRC) Processes in Science

    Shen, Ji; Sung, Shannon; Zhang, Dongmei

    2015-11-01

    Students need to think and work across disciplinary boundaries in the twenty-first century. However, it is unclear what interdisciplinary thinking means and how to analyze interdisciplinary interactions in teamwork. In this paper, drawing on multiple theoretical perspectives and empirical analysis of discourse contents, we formulate a theoretical framework that helps analyze interdisciplinary reasoning and communication (IRC) processes in interdisciplinary collaboration. Specifically, we propose four interrelated IRC processes-integration, translation, transfer, and transformation, and develop a corresponding analytic framework. We apply the framework to analyze two meetings of a project that aims to develop interdisciplinary science assessment items. The results illustrate that the framework can help interpret the interdisciplinary meeting dynamics and patterns. Our coding process and results also suggest that these IRC processes can be further examined in terms of interconnected sub-processes. We also discuss the implications of using the framework in conceptualizing, practicing, and researching interdisciplinary learning and teaching in science education.

  3. The Factors that Affect Science Teachers' Participation in Professional Development

    Science.gov (United States)

    Roux, Judi Ann

    Scientific literacy for our students and the possibilities for careers available in Science, Technology, Engineering, and Mathematics (STEM) areas are important topics for economic growth as well as global competitiveness. The achievement of students in science learning is dependent upon the science teachers' effectiveness and experienced science teachers depend upon relevant professional development experiences to support their learning. In order to understand how to improve student learning in science, the learning of science teachers must also be understood. Previous research studies on teacher professional development have been conducted in other states, but Minnesota science teachers comprised a new and different population from those previously studied. The purpose of this two-phase mixed methods study was to identify the current types of professional development in which experienced, Minnesota secondary science teachers participated and the factors that affect their participation in professional development activities. The mixed-methods approach s utilized an initial online survey followed by qualitative interviews with five survey respondents. The results of the quantitative survey and the qualitative interviews indicated the quality of professional development experiences and the factors which affected the science teachers' participation in professional development activities. The supporting and inhibiting factors involved the availability of resources such as time and money, external relationships with school administrators, teacher colleagues, and family members, and personal intrinsic attributes such as desires to learn and help students. This study also describes implications for science teachers, school administrators, policymakers, and professional development providers. Recommendations for future research include the following areas: relationships between and among intrinsic and extrinsic factors, science-related professional development activities

    2017-11-14

    The ability to conduct multiple experiments in parallel significantly reduces the time that it takes to develop a manufacturing process for a biopharmaceutical. This is particularly significant before clinical entry, because process development and manufacturing are on the "critical path" for a drug candidate to enter clinical development. High-throughput process development (HTPD) methodologies can be similarly impactful during late-stage development, both for developing the final commercial process as well as for process characterization and scale-down validation activities that form a key component of the licensure filing package. This review examines the current state of the art for HTPD methodologies as they apply to cell culture, downstream purification, and analytical techniques. In addition, we provide a vision of how HTPD activities across all of these spaces can integrate to create a rapid process development engine that can accelerate biopharmaceutical drug development.

  5. Decolonizing Science and Science Education in a Postcolonial Space (Trinidad, a Developing Caribbean Nation, Illustrates

    Directory of Open Access Journals (Sweden)

    Laila N. Boisselle

    2016-03-01

    Full Text Available The article addresses how remnant or transformed colonialist structures continue to shape science and science education, and how that impact might be mitigated within a postcolonial environment in favor of the development of the particular community being addressed. Though cognizant of, and resistant to, the ongoing colonial impact globally and nationally (and any attempts at subjugation, imperialism, and marginalization, this article is not about anticolonial science. Indeed, it is realized that the postcolonial state of science and science education is not simply defined, and may exist as a mix of the scientific practices of the colonizer and the colonized. The discussion occurs through a generic postcolonial lens and is organized into two main sections. First, the discussion of the postcolonial lens is eased through a consideration of globalization which is held here as the new colonialism. The article then uses this lens to interrogate conceptions of science and science education, and to suggest that the mainstream, standard account of what science is seems to represent a globalized- or arguably a Western, modern, secular-conception of science. This standard account of science can act as a gatekeeper to the indigenous ways of being, knowing, and doing of postcolonial populations. The article goes on to suggest that as a postcolonial response, decolonizing science and science education might be possible through practices that are primarily contextually respectful and responsive. That is, localization is suggested as one possible antidote to the deleterious effects of globalization. Trinidad, a postcolonial developing Caribbean nation, is used as illustration.

    Chaffee, Rachel L.

    This dissertation study contributes to the research on filmmaking and identity development by exploring the ways that film production provided unique opportunities for a team of four girls to engage in science, to develop identities in science, and to see and understand science differently. Using social practice, identity, and feminist theory and New Literacies Studies as a theoretical lens and grounded theory and multimodality as analytic frameworks, I present findings that suggest that girls in this study authored identities and communicated and represented science in and through film in ways that drew on their social, cultural, and embodied resources and the material resources of the after-school science club. Findings from this study highlight the affordances of filmmaking as a venue for engaging in the disciplinary practices of science and for accessing and authoring identities in science.

  7. Development environmental attitude of prospective science teachers

    2000-01-01

    Since the last three decades or so, we have witnessed the growing concern of human beings, all over the world, to adopt measures to conserve and preserve environment of the planet earth, because the same has been threatened by human activity and by way of our unparalleled intervention in the otherwise balanced environment. This awareness and concern has emerged as a need of incorporating environmental Issues into the normal curricula, so that we can educate the young generation to become informed decision-makers of the future. UNESCO and UNEP have advocated (since the last three decades) to teach environmentalised science to students. In Pakistan, there have been attempts to change curricula in accordance with the need of the time. Teachers need new kinds of skills, attitudes and commitment to teach science in an environmentalised fashion. This article discusses the impact of a semester-course on change in environmental attitudes of prospective science-teachers. A pre-test, post-test method was used to ascertain any change in environmental attitude of prospective science-teachers, after studying the environmental education course. It has been shown that there was a change in the environmental attitude of science-teachers as a result of the one-semester course, but the change or the level of attitude was not substantial or satisfactory. There seems to be a need of adopting a comprehensive approach to environmental education, and introducing teaching of environmental concepts at a very early age. (author)

    2016-03-01

    The teaching and learning of science in school are influenced by various factors, including both individual factors, such as member beliefs, and social factors, such as the power structure of the class. To understand this complex context affected by various factors in schools, we investigated the formation and sharing process of science classroom norms in connection with these factors. By examining the developmental process of science classroom norms, we identified how the norms were realized, shared, and internalized among the members. We collected data through classroom observations and interviews focusing on two elementary science classrooms in Korea. From these data, factors influencing norm formation were extracted and developed as stories about norm establishment. The results indicate that every science classroom norm was established, shared, and internalized differently according to the values ingrained in the norms, the agent of norm formation, and the members' understanding about the norm itself. The desirable norms originating from values in science education, such as having an inquiring mind, were not established spontaneously by students, but were instead established through well-organized norm networks to encourage concrete practice. Educational implications were discussed in terms of the practice of school science inquiry, cultural studies, and value-oriented education.

  10. Development of novel microencapsulation processes

    Yin, Weisi

    of polymer solution suspended in water or from a spray. Hollow PS particles were obtained by swelling PS latex with solvent, freezing in liquid nitrogen, and drying in vacuum. It is shown that the particle morphology is due to phase separation in the polymer emulsion droplets upon freezing in liquid nitrogen, and that morphological changes are driven largely by lowering interfacial free energy. The dried hollow particles were resuspended in a dispersing media and exposed to a plasticizer, which imparts mobility to polymer chains, to close the surface opening and form microcapsules surrounding an aqueous core. The interfacial free energy difference between the hydrophobic inside and hydrophilic outside surfaces is the major driving force for closing the hole on the surface. A controlled release biodegradable vehicle for drug was made by encapsulating procaine hydrochloride, a water-soluble drug, into the core of poly(DL-lactide) (PLA) microcapsules, which were made by the freeze-drying and subsequent closing process. The encapsulation efficiency is affected by the hollow particle morphology, amount of closing agent, exposure time, surfactant, and method of dispersing the hollow particles in water. Controlled release of procaine hydrochloride from the microcapsules into phosphate buffer was observed. The use of benign solvents dimethyl carbonate in spray/freeze-drying and CO2 for closing would eliminate concerns of residual harmful solvent in the product. The ease of separation of CO2 from the drug solution may also enable recycling of the drug solution to increase the overall encapsulation efficiency using these novel hollow particles.

    Grady, Julie R; Dolan, Erin L; Glasson, George E

    2010-01-01

    Students' experiences with science integrated into agriscience courses contribute to their developing epistemologies of science. The purpose of this case study was to gain insight into the implementation of scientific inquiry in an agriscience classroom. Also of interest was how the tenets of the nature of science were reflected in the students' experiments. Participants included an agriscience teacher and her fifteen students who were conducting plant experiments to gain insight into the role of a gene disabled by scientists. Data sources included classroom observations, conversations with students, face-to-face interviews with the teacher, and students' work. Analysis of the data indicated that the teacher viewed scientific inquiry as a mechanical process with little emphasis on the reasoning that typifies scientific inquiry. Students' participation in their experiments also centered on the procedural aspects of inquiry with little attention to scientific reasoning. There was no explicit attention to the nature of science during the experiments, but the practice implied correct, incorrect, and underdeveloped conceptions of the nature of science. Evidence from the study suggests a need for collaboration between agriscience and science teacher educators to design and conduct professional development focused on scientific inquiry and nature of science for preservice and practicing teachers.

    The aim of the book is to give an accessible introduction of mathematical models and signal processing methods in speech and hearing sciences for senior undergraduate and beginning graduate students with basic knowledge of linear algebra, differential equations, numerical analysis, and probability. Speech and hearing sciences are fundamental to numerous technological advances of the digital world in the past decade, from music compression in MP3 to digital hearing aids, from network based voice enabled services to speech interaction with mobile phones. Mathematics and computation are intimately related to these leaps and bounds. On the other hand, speech and hearing are strongly interdisciplinary areas where dissimilar scientific and engineering publications and approaches often coexist and make it difficult for newcomers to enter.

    At Goddard, engineers and scientists with a range of experience in science data systems are needed to employ new technologies and develop advances in capabilities for supporting new Earth and Space science research. Engineers with extensive experience in science data, software engineering and computer-information architectures are needed to lead and perform these activities. The increasing types and complexity of instrument data and emerging computer technologies coupled with the current shortage of computer engineers with backgrounds in science has led the need to develop a career path for science data systems engineers and architects.The current career path, in which undergraduate students studying various disciplines such as Computer Engineering or Physical Scientist, generally begins with serving on a development team in any of the disciplines where they can work in depth on existing Goddard data systems or serve with a specific NASA science team. There they begin to understand the data, infuse technologies, and begin to know the architectures of science data systems. From here the typical career involves peermentoring, on-the-job training or graduate level studies in analytics, computational science and applied science and mathematics. At the most senior level, engineers become subject matter experts and system architect experts, leading discipline-specific data centers and large software development projects. They are recognized as a subject matter expert in a science domain, they have project management expertise, lead standards efforts and lead international projects. A long career development remains necessary not only because of the breadth of knowledge required across physical sciences and engineering disciplines, but also because of the diversity of instrument data being developed today both by NASA and international partner agencies and because multidiscipline science and practitioner communities expect to have access to all types of observational data

    Prototypes of medical devices are made in accordance with the needs of clinical practice, and for systems required during the initial process of medical device development for new surgical practices. Verification of whether these prototypes produce the intended performance specifications is conducted using basic tests such as mechanical and animal tests. The prototypes are then improved and modified until satisfactory results are obtained. After a prototype passes through a clinical trial process similar to that for new drugs, application for approval is made. In the approval application process, medical devices are divided into new, improved, and generic types. Reviewers judge the validity of intended use, indications, operation procedures, and precautions, and in addition evaluate the balance between risk and benefit in terms of efficacy and safety. Other characteristics of medical devices are the need for the user to attain proficiency in usage techniques to ensure efficacy and safety, and the existence of a variety of medical devices for which assessment strategies differ, including differences in impact on the body in cases in which a physical burden to the body or failure of a medical device develops. Regulatory science of medical devices involves prediction, judgment, and evaluation of efficacy, safety, and quality, from which data result which can become indices in the development stages from design to application for approval. A reduction in the number of animals used for testing, improvement in efficiency, reduction of the necessity for clinical trials, etc. are expected through rational setting of evaluation items.

    The Web was originally developed to support collaboration in science. Although scientists benefit from many forms of collaboration on the Web (e.g., blogs, wikis, forums, code sharing, etc.), most collaborative projects are coordinated over email, phone calls, and in-person meetings. Our goal is to develop a collaborative infrastructure for scientists to work on complex science questions that require multi-disciplinary contributions to gather and analyze data, that cannot occur without significant coordination to synthesize findings, and that grow organically to accommodate new contributors as needed as the work evolves over time. Our approach is to develop an organic data science framework based on a task-centered organization of the collaboration, includes principles from social sciences for successful on-line communities, and exposes an open science process. Our approach is implemented as an extension of a semantic wiki platform, and captures formal representations of task decomposition structures, relations between tasks and users, and other properties of tasks, data, and other relevant science objects. All these entities are captured through the semantic wiki user interface, represented as semantic web objects, and exported as linked data.

    A Science process skill (SPS) is a fundamental scientific method to achieve good knowledge. SPS can be categorized into two levels: basic and integrated. Learning SPS helps children to grow as individuals who can access knowledge and know how to acquire it. The primary outcomes of the scientific process in learning are the application of scientific processes, scientific reasoning, accurate knowledge, problem-solving, and understanding of the relationship between science, technology, society, and everyday life’s events. Teachers’ understanding of SPS is central to the application of SPS in a learning process. Following this point, this study aims to investigate the high school chemistry teachers’ understanding of SPS pertains to their assessment of SPS in chemistry learning. The understanding of SPS is measured from the conceptual and operational aspects of SPS. This research uses qualitative analysis method, and the sample consists of eight chemistry teachers selected by random sampling. A semi-structured interview procedure is used to collect the data. The result of the analysis shows that teachers’ conceptual and operational understanding of SPS is weak. It affects the accuracy and appropriateness of the teacher’s selection of SPS assessment in chemistry learning.

    The concept of materials science tetrahedron (MST) concisely depicts the inter-dependent relationship among the structure, properties, performance, and processing of a drug. Similar to its role in traditional materials science, MST encompasses the development in the emerging field of pharmaceutical materials science and forms a scientific foundation to the design and development of new drug products. Examples are given to demonstrate the applicability of MST to both pharmaceutical research and product development. It is proposed that a systematic implementation of MST can expedite the transformation of pharmaceutical product development from an art to a science. By following the principle of MST, integration of research among different laboratories can be attained. The pharmaceutical science community as a whole can conduct more efficient, collaborative, and coherent research.

    2009-06-01

    In this manuscript we examine how two students develop and express agency in and through high school physics. We tell the stories of two youth from a low-income, urban community to elucidate the important components of critical science agency in a physics context, and to situate a set of claims about how youth develop and express this concept. This research is part of a larger multiyear study of democratic practice in middle- and high-school science. We present three claims: (a) that critical science agency is intimately related to the leveraging and development of identity, (b) that critical science agency involves the strategic deployment of resources , and (c) that developing critical science agency is an iterative and generative process. Two university researchers have co-written this paper with the two students whose experiences serve as the cases under investigation, to provide both an "emic" perspective and student-focused voices that complement and challenge the researchers' voices.

    The study explored the changes in pre-service science teachers' understanding of the nature of science and their opinions about the nature of science, science teaching and argumentation after their participation in explicit nature of science (NOS) and socioscientific argumentation processes. The participants were 56 third-grade pre-service science teachers studying in a state university in Turkey. The treatment group comprised 27 participants, and there were 29 participants in the comparison group. The comparison group participants were involved in a student-centred science-teaching process, and the participants of the treatment group were involved in explicit NOS and socioscientific argumentation processes. In the study, which lasted a total of 11 weeks, a NOS-as-argumentation questionnaire was administered to all the participants to determine their understanding of NOS at the beginning and end of the data collection process, and six random participants of the treatment group participated in semi-structured interview questions in order to further understand their views regarding NOS, science teaching and argumentation. Qualitative and quantitative data analysis revealed that the explicit NOS and socioscientific argumentation processes had a significant effect on pre-service science teachers' NOS understandings. Furthermore, NOS, argumentation and science teaching views of the participants in the treatment group showed a positive change. The results of this study are discussed in light of the related literature, and suggestions are made within the context of contribution to science-teaching literature, improvement of education quality and education of pre-service teachers.

    Michigan Technological University has developed a collaborative process for designing summer field courses for teachers as part of their National Science Foundation funded Math Science Partnership program, called the Michigan Teacher Excellence Program (MiTEP). This design process was implemented and then piloted during two two-week courses: Earth Science Institute I (ESI I) and Earth Science Institute II (ESI II). Participants consisted of a small group of Michigan urban science teachers who are members of the MiTEP program. The Earth Science Literacy Principles (ESLP) served as the framework for course design in conjunction with input from participating MiTEP teachers as well as research done on common teacher and student misconceptions in Earth Science. Research on the Earth Science misconception component, aligned to the ESLP, is more fully addressed in GSA Abstracts with Programs Vol. 42, No. 5. “Recognizing Earth Science Misconceptions and Reconstructing Knowledge through Conceptual-Change-Teaching”. The ESLP were released to the public in January 2009 by the Earth Science Literacy Organizing Committee and can be found at http://www.earthscienceliteracy.org/index.html. Each day of the first nine days of both Institutes was focused on one of the nine ESLP Big Ideas; the tenth day emphasized integration of concepts across all of the ESLP Big Ideas. Throughout each day, Michigan Tech graduate student facilitators and professors from Michigan Tech and Grand Valley State University consistantly focused teaching and learning on the day's Big Idea. Many Earth Science experts from Michigan Tech and Grand Valley State University joined the MiTEP teachers in the field or on campus, giving presentations on the latest research in their area that was related to that Big Idea. Field sites were chosen for their unique geological features as well as for the “sense of place” each site provided. Preliminary research findings indicate that this collaborative design

    Wind, Stefanie A; Alemdar, Meltem; Lingle, Jeremy A; Gale, Jessica D; Moore, Roxanne A

    Recent reforms in science education worldwide include an emphasis on engineering design as a key component of student proficiency in the Science, Technology, Engineering, and Mathematics disciplines. However, relatively little attention has been directed to the development of psychometrically sound assessments for engineering. This study demonstrates the use of mixed methods to guide the development and revision of K-12 Engineering Design Process (EDP) assessment items. Using results from a middle-school EDP assessment, this study illustrates the combination of quantitative and qualitative techniques to inform item development and revisions. Overall conclusions suggest that the combination of quantitative and qualitative evidence provides an in-depth picture of item quality that can be used to inform the revision and development of EDP assessment items. Researchers and practitioners can use the methods illustrated here to gather validity evidence to support the interpretation and use of new and existing assessments.

    Serious scientific games, especially those that include a virtual apprenticeship component, provide players with realistic experiences in science. This article discusses how science games can influence learning about science and the development of science-oriented possible selves through repeated practice in professional play and through social influences (e.g., peer groups). We first review the theory of possible selves (Markus and Nurius 1986) and discuss the potential of serious scientific games for influencing the development of scientific possible selves. As part of our review, we present a forensic game that inspired our work. Next we present a measure of scientific possible selves and assess its reliability and validity with a sample of middle-school students ( N = 374). We conclude by discussing the promise of science games and the development of scientific possible selves on both the individual and group levels as a means of inspiring STEM careers among adolescents.

    2005-10-01

    This paper reports a study to inform curriculum development by exploring the contribution of bioscience education programmes to nurses' clinical practice, their understanding of the rationale for practice, and their perceptions of their continuing professional development needs. The future of the health services worldwide depends on nurse education programmes equipping practitioners to deliver safe and effective patient care. In the developed world, the structure and indicative content of nursing curricula have been debated extensively. However, despite the rapid expansion in nursing roles brought about by social change, there is little information on the educational needs of nurses in developing countries. This study was undertaken in government teaching hospitals in Cape Town, South Africa in 2003. A purposive sample of 54 nurses from a range of clinical settings completed questionnaires and described critical incidents where bioscience knowledge had directed practice. Questionnaires were analysed descriptively, in the main. Analysis of critical incident reports was based on Akinsanya's bionursing model. Most nurses felt that their understanding of the biological, but not the physical sciences, was adequate or better: all felt confident with their knowledge of anatomy, compared with 57.4% (31/54) for microbiology. Respondents attributed the successes and failures of their education programmes to their teachers' delivery of content, ability to relate to practice and management of the process of learning. The biological, but not the physical, sciences were universally (96-100%) regarded as relevant to nursing. However, the critical incidents and nurses' own reports indicated a need for further education in pharmacology (40/54, 74.1%) and microbiology (29/54, 53.7%). To meet the needs of nurses in developing countries, and empower them to meet the increasingly complex demands of their expanding roles, nurse educators need to consider increasing the curriculum

    2009-03-01

    Self-reflection is a tool of instruction that has been used in the science classroom. Research has shown great promise in using video as a learning tool in the classroom. However, the integration of self-reflective practice using video in the general chemistry laboratory to help students develop process skills has not been done. Immediate video feedback and direct instruction were employed in a general chemistry laboratory course to improve students' mastery and understanding of basic and advanced process skills. Qualitative results and statistical analysis of quantitative data proved that self-reflection significantly helped students develop basic and advanced process skills, yet did not seem to influence the general understanding of the science content.

  20. EUV mask process specifics and development challenges

    Nesladek, Pavel

    2014-07-01

    EUV lithography is currently the favorite and most promising candidate among the next generation lithography (NGL) technologies. Decade ago the NGL was supposed to be used for 45 nm technology node. Due to introduction of immersion 193nm lithography, double/triple patterning and further techniques, the 193 nm lithography capabilities was greatly improved, so it is expected to be used successfully depending on business decision of the end user down to 10 nm logic. Subsequent technology node will require EUV or DSA alternative technology. Manufacturing and especially process development for EUV technology requires significant number of unique processes, in several cases performed at dedicated tools. Currently several of these tools as e.g. EUV AIMS or actinic reflectometer are not available on site yet. The process development is done using external services /tools with impact on the single unit process development timeline and the uncertainty of the process performance estimation, therefore compromises in process development, caused by assumption about similarities between optical and EUV mask made in experiment planning and omitting of tests are further reasons for challenges to unit process development. Increased defect risk and uncertainty in process qualification are just two examples, which can impact mask quality / process development. The aim of this paper is to identify critical aspects of the EUV mask manufacturing with respect to defects on the mask with focus on mask cleaning and defect repair and discuss the impact of the EUV specific requirements on the experiments needed.

  6. Framing the inborn aging process and longevity science.

    Science.gov (United States)

    Farrelly, Colin

    2010-06-01

    The medical sciences are currently dominated by the "disease-model" approach to health extension, an approach that prioritizes the study of pathological mechanisms with the goal of discovering treatment modalities for specific diseases. This approach has marginalized research on the aging process itself, research that could lead to an intervention that retards aging, thus conferring health dividends that would far exceed what could be expected by eliminating any specific disease of aging. This paper offers a diagnosis of how this sub-optimal approach to health extension arose and some general prescriptions concerning how progress could be made in terms of adopting a more rational approach to health extension. Drawing on empirical findings from psychology and economics, "prospect theory" is applied to the challenges of "framing" the inborn aging process given the cognitive capacities of real (rather than rational) decision-makers under conditions of risk and uncertainty. Prospect theory reveals that preferences are in fact dependent on whether particular outcomes of a choice are regarded as "a loss" or "a gain", relative to a reference point (or "aspiration level for survival"). And this has significant consequences for the way biogerontologists ought to characterise the central aspirations of the field (i.e. to prevent disease versus extend lifespan). Furthermore, it reveals the importance of shifting the existing reference point of the medical sciences to one that is shaped by the findings of evolutionary biology and biodemography.

  8. The cognitive viewpoint on information science and processing information in cognitive psychology - a vision for interdisciplinary

    Directory of Open Access Journals (Sweden)

    Shirley Guimarães Pimenta

    2012-08-01

    Full Text Available The interaction amongst the ‘user’, ‘information’, and ‘text’ is of interest to Information Science although it has deserved insufficient attention in the literature. This issue is addressed by this paper whose main purpose is to contribute to the discussion of theoretical affinity between the cognitive viewpoint in Information Science and the information processing approach in Cognitive Psychology. Firstly, the interdisciplinary nature of Information Science is discussed and justified as a means to deepen and strengthen its theoretical framework. Such interdisciplinarity helps to avoid stagnation and keep pace with other disciplines. Secondly, the discussion takes into consideration the cognitive paradigm, which originates the cognitive viewpoint approach in Information Science. It is highlighted that the cognitive paradigm represented a change in the Social Sciences due to the shift of focus from the object and the signal to the individual. Besides that, it sheds light to the notion of models of worlds, i.e., the systems of categories and concepts that guide the interaction between the individual and his/her environment. Thirdly, the theoretical assumptions of the cognitive viewpoint approach are discussed, with emphasis on the concept of ‘information’, as resulting of cognitive processes and as related to the notion of ‘text’. This approach points out the relevance of understanding the interaction amongst users, information, and text. However, it lacks further development. Using notions which are common to both approaches, some of the gaps can be fulfilled. Finally, the concept of ‘text’, its constituents and structures are presented from the perspective of text comprehension models and according to the information processing approach. As a concluding remark, it is suggested that bringing together the cognitive viewpoint and the information processing approach can be enriching and fruitful to the both Information

  9. Belowground Carbon Cycling Processes at the Molecular Scale: An EMSL Science Theme Advisory Panel Workshop

    Energy Technology Data Exchange (ETDEWEB)

    Hess, Nancy J.; Brown, Gordon E.; Plata, Charity

    2014-02-21

    As part of the Belowground Carbon Cycling Processes at the Molecular Scale workshop, an EMSL Science Theme Advisory Panel meeting held in February 2013, attendees discussed critical biogeochemical processes that regulate carbon cycling in soil. The meeting attendees determined that as a national scientific user facility, EMSL can provide the tools and expertise needed to elucidate the molecular foundation that underlies mechanistic descriptions of biogeochemical processes that control carbon allocation and fluxes at the terrestrial/atmospheric interface in landscape and regional climate models. Consequently, the workshop's goal was to identify the science gaps that hinder either development of mechanistic description of critical processes or their accurate representation in climate models. In part, this report offers recommendations for future EMSL activities in this research area. The workshop was co-chaired by Dr. Nancy Hess (EMSL) and Dr. Gordon Brown (Stanford University).

  10. Beyond the lab: observations on the process by which science successfully informs management and policy decisions

    Science.gov (United States)

    Flores, S.

    2012-12-01

    Scientific findings inform management decisions and policy products through various ways, these include: synthesis reports, white papers, in-person and web-based seminars (webinars), communication from specialized staff, and seminal peer-reviewed journal articles. Scientists are often told that if they want their science to inform management decisions and policy products that they must: clearly and simply articulate discreet pieces of scientific information and avoid attaching advocacy messages to the science; however, solely relying on these tenants does not ensure that scientific products will infuse the realms of management and policy. The process by which science successfully informs management decisions and policy products rarely begins at the time the results come out of the lab, but rather, before the research is carried out. Having an understanding of the political climate, management needs, agency research agendas, and funding limitations, as well as developing a working relationship with the intended managers and policy makers are key elements to developing the kind of science results and products that often make an impact in the management and policy world. In my presentation I will provide case-studies from California (USA) to highlight the type of coastal, ocean and climate science that has been successful in informing management decisions and policy documents, as well as provide a state-level agency perspective on the process by which this occurs.

    2012-10-01

    Full Text Available In practice, there are several approaches in discussing the achieved level of development of a scientific discipline. One group of them concentrates on external indicators of the development of a scientific discipline, i.e. its research network, while the other group analyzes the science structure, i.e. its elements. The achieved level of the development of the defense system and its (external and internal environment, general knowledge on the development and the systematic treatment of science as well as the present situation in the society require an insight into the internal and external indicators of the development of defense logistics as a scientific discipline (Defense Science. General knowledge on the creation, development and interdependence of sciences as well as internal and external indicators of the achieved development level of Defense Logistics show that it should be developed in the network environment as a multidisciplinary science, in close cooperation with other special disciplines of logistics, within defense science. It could thus contribute to the improvement of the defense as an important public function as well as to closer contacts of the scientific disciplines dealing with technical systems and technologies with the so-called. orthodox military disciplines.

  16. THE DEVELOPMENT OF BOOK SCIENCE IN LITHUANIA: DIVISION INTO PERIODS AND CHRONOLOGY

    Directory of Open Access Journals (Sweden)

    Navickiene, Ausra

    2006-12-01

    science in Lithuania also coincided with the development in Europe where an independent discipline investigating a book and book matter emerged at the beginning of the 20th century. At that time Lithuania as earlier, book science was equal with other humanities’ disciplines, which were institutionalised and developed in different directions without adding original theoretical works. As in Russia and Poland, book science in Lithuania did not pass through the library period of book science as it happened in Germany where an innovative library science included a wide part of historical and theoretical book research issues. After the Second World War, the Soviet “fashions” in book science influenced it’s development in Lithuania most. It was not impossible to continue the work started during the years of independence and the traditional book science was not developed, the applied and historical issues were the limit. The changing Russian and European political and science situation during 60s stimulated the renaissance of book science in Lithuania. The term book science came back intothe use, the journal Knygotyra was established, monographs on different issues of book science were published and other facts evidenced this return. The process continues till now. In modernLithuania, the traditional book science is developed. It is the main concern of a recreated academic department at Vilnius University, which is actively promoting book science and organizing studiesof book science.

    Babaie, Mahya

    The purpose of this quantitative, descriptive, single group, pretest posttest design study was to explore the influence of a Virtual Science Laboratory (VSL) on middle school students' cognitive knowledge, skill development, and attitudes toward science. This study involved 2 eighth grade Physical Science classrooms at a large urban charter middle school located in Southern California. The Buoyancy and Density Test (BDT), a computer generated test, assessed students' scientific knowledge in areas of Buoyancy and Density. The Attitude Toward Science Inventory (ATSI), a multidimensional survey assessment, measured students' attitudes toward science in the areas of value of science in society, motivation in science, enjoyment of science, self-concept regarding science, and anxiety toward science. A Virtual Laboratory Packet (VLP), generated by the researcher, captured students' mathematical and scientific skills. Data collection was conducted over a period of five days. BDT and ATSI assessments were administered twice: once before the Buoyancy and Density VSL to serve as baseline data (pre) and also after the VSL (post). The findings of this study revealed that students' cognitive knowledge and attitudes toward science were positively changed as expected, however, the results from paired sample t-tests found no statistical significance. Analyses indicated that VSLs were effective in supporting students' scientific knowledge and attitude toward science. The attitudes most changed were value of science in society and enjoyment of science with mean differences of 1.71 and 0.88, respectively. Researchers and educational practitioners are urged to further examine VSLs, covering a variety of topics, with more middle school students to assess their learning outcomes. Additionally, it is recommended that publishers in charge of designing the VSLs communicate with science instructors and research practitioners to further improve the design and analytic components of these

  1. Process tracing in political science: What's the story?

    Science.gov (United States)

    Crasnow, Sharon

    2017-04-01

    Methodologists in political science have advocated for causal process tracing as a way of providing evidence for causal mechanisms. Recent analyses of the method have sought to provide more rigorous accounts of how it provides such evidence. These accounts have focused on the role of process tracing for causal inference and specifically on the way it can be used with case studies for testing hypotheses. While the analyses do provide an account of such testing, they pay little attention to the narrative elements of case studies. I argue that the role of narrative in case studies is not merely incidental. Narrative does cognitive work by both facilitating the consideration of alternative hypotheses and clarifying the relationship between evidence and explanation. I consider the use of process tracing in a particular case (the Fashoda Incident) in order to illustrate the role of narrative. I argue that process tracing contributes to knowledge production in ways that the current focus on inference tends to obscure. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2013-01-28

    This paper describes the e-Science Central (e-SC) cloud data processing system and its application to a number of e-Science projects. e-SC provides both software as a service (SaaS) and platform as a service for scientific data management, analysis and collaboration. It is a portable system and can be deployed on both private (e.g. Eucalyptus) and public clouds (Amazon AWS and Microsoft Windows Azure). The SaaS application allows scientists to upload data, edit and run workflows and share results in the cloud, using only a Web browser. It is underpinned by a scalable cloud platform consisting of a set of components designed to support the needs of scientists. The platform is exposed to developers so that they can easily upload their own analysis services into the system and make these available to other users. A representational state transfer-based application programming interface (API) is also provided so that external applications can leverage the platform's functionality, making it easier to build scalable, secure cloud-based applications. This paper describes the design of e-SC, its API and its use in three different case studies: spectral data visualization, medical data capture and analysis, and chemical property prediction.

    Kramer, Maxwell; Olson, Dalay; Walker, J D

    2018-06-01

    Explicit emphasis on teaching science process skills leads to both gains in the skills themselves and, strikingly, deeper understanding of content. Here, we created and tested a series of online, interactive tutorials with the goal of helping undergraduate students develop science process skills. We designed the tutorials in accordance with evidence-based multimedia design principles and student feedback from usability testing. We then tested the efficacy of the tutorials in an introductory undergraduate biology class. On the basis of a multivariate ordinary least-squares regression model, students who received the tutorials are predicted to score 0.82 points higher on a 15-point science process skill assessment than their peers who received traditional textbook instruction on the same topic. This moderate but significant impact indicates that well-designed online tutorials can be more effective than traditional ways of teaching science process skills to undergraduate students. We also found trends that suggest the tutorials are especially effective for nonnative English-speaking students. However, due to a limited sample size, we were unable to confirm that these trends occurred due to more than just variation in the student group sampled.

    Science data digital repositories are entrusted to ensure that a science community's data are available and useful to users both today and in the future. Part of the challenge in meeting this responsibility is identifying the standards, policies and procedures required to accomplish effective data preservation. Subsequently a repository should be evaluated on whether or not they are effective in their data preservation efforts. This poster will outline the process by which digital repositories are being formally evaluated in terms of their ability to preserve the digitally encoded information with which they have been entrusted. The ISO standards on which this is based will be identified and the relationship of these standards to the Open Archive Information System (OAIS) reference model will be shown. Six test audits have been conducted with three repositories in Europe and three in the USA. Some of the major lessons learned from these test audits will be briefly described. An assessment of the possible impact of this type of audit and certification on the practice of preserving digital information will also be provided.

  12. Quality Science Teacher Professional Development and Student Achievement

    Science.gov (United States)

    Dubner, J.

    2007-12-01

    Studies show that socio-economic background and parental education accounts for 50-60 percent of a child's achievement in school. School, and other influences, account for the remaining 40-50 percent. In contrast to most other professions, schools require no real apprenticeship training of science teachers. Overall, only 38 percent of United States teachers have had any on-the-job training in their first teaching position, and in some cases this consisted of a few meetings over the course of a year between the beginning teacher and the assigned mentor or master teacher. Since individual teachers determine the bulk of a student's school experiences, interventions focused on teachers have the greatest likelihood of affecting students. To address this deficiency, partnerships between scientists and K-12 teachers are increasingly recognized as an excellent method for improving teacher preparedness and the quality of science education. Columbia University's Summer Research Program for Science Teachers' (founded in 1990) basic premise is simple: teachers cannot effectively teach science if they have no firsthand experience doing science, hence the Program's motto, "Practice what you teach." Columbia University's Summer Research Program for Science Teachers provides strong evidence that a teacher research program is a very effective form of professional development for secondary school science teachers and has a direct correlation to increased student achievement in science. The author will present the methodology of the program's evaluation citing statistically significant data. The author will also show the economic benefits of teacher participation in this form of professional development.

    2001-12-03

    The objective of this effort is to benchmark the development of process-based quality tools for application in CAD (computer-aided design) model-based applications. The processes of interest are design, manufacturing, and quality process applications. A study was commissioned addressing the impact, current technologies, and known problem areas in application of 3D MCAD (3-dimensional mechanical computer-aided design) models and model integrity on downstream manufacturing and quality processes. The downstream manufacturing and product quality processes are profoundly influenced and dependent on model quality and modeling process integrity. The goal is to illustrate and expedite the modeling and downstream model-based technologies for available or conceptual methods and tools to achieve maximum economic advantage and advance process-based quality concepts.

  11. Explainers' development of science-learner identities through participation in a community of practice

    Science.gov (United States)

    Richardson, Anne E.

    The urgent environmental issues of today require science-literate adults to engage in business and political decisions to create solutions. Despite the need, few adults have the knowledge and skills of science literacy. This doctoral dissertation is an analytical case study examining the science-learner identity development of Exploratorium Field Trip Explainers. Located in San Francisco, CA, the Exploratorium is a museum of science, art, and human perception dedicated to nurturing curiosity and exploration. Data collected included semi-structured interviews with sixteen former Field Trip Explainers, participant observation of the current Field Trip Explainer Program, and review of relevant documentation. Data analysis employed constant comparative analysis, guided by the communities of practice theoretical framework (Wenger, 1998) and the National Research Council's (2009) Six Strands of Science Learning. Findings of this research indicate that Exploratorium Field Trip Explainers participate in a community of practice made up of a diverse group of people that values curiosity and openness to multiple ways of learning. Many participants entered the Field Trip Explainer Program with an understanding of science learning as a rigid process reserved for a select group of people; through participation in the Field Trip Explainer community of practice, participants developed an understanding of science learning as accessible and a part of everyday life. The findings of this case study have implications for research, theory, and practice in informal adult science learning, access of non-dominant groups to science learning, and adult workplace learning in communities of practice.

  12. Developing a constructivist learning environment in online postsecondary science courses

    Science.gov (United States)

    Hackworth, Sylvester N.

    This Delphi study addressed the concerns of postsecondary educators regarding the quality of education received by postsecondary science students who receive their instruction online. This study was framed with the constructivist learning theory and Piaget's and Dewey's cognitive development theories. The overarching question addressed a gap in research literature surrounding the pedagogical practices that could be successfully applied to future postsecondary online science education. The panel consisted of 30 experts in the area of online postsecondary education. Qualitative data from the initial seed questions were used to create a Likert-type survey to seek consensus of the themes derived from participant responses. Participants reached agreement on six items: apply constructivism to science curricula, identify strengths and challenges of online collegiate students, explicate students' consequences due to lack of participation in discussion forums, ensure that online course content is relevant to students' lives, reinforce academic integrity, and identify qualities face-to-face collegiate science instructors need when transitioning to online science instructors. The majority of participants agreed that gender is not an important factor in determining the success of an online collegiate science student. There was no consensus on the efficacy of virtual labs in an online science classroom. This study contributes to positive social change by providing information to new and struggling postsecondary science teachers to help them successfully align their instruction with students' needs and, as a result, increase students' success.

    As the sciences advanced rapidly in the modern European world, outstanding achievements have been made in medicine, chemistry, biology, physiology, physics and others, which have been co-influencing each of the scientific disciplines. Accordingly, such medical and scientific phenomena began to be reflected in novels. In particular, Mary Shelley's Frankenstein includes the diverse aspects of the change and development in the medicine and science. Associated with medical and scientific information reflected in Frankenstein and Frankenstein's experiments in the text, accordingly, this research will investigate the aspects of medical and scientific development taking place in the nineteenth century in three ways. First, the medical and scientific development of the nineteenth century has been reviewed by summerizing both the information of alchemy in which Frankenstein shows his interest and the new science in general that M. Waldman introduces in the text. Second, the actual features of medical and scientific development have been examined through some examples of the experimental methods that M. Waldman implicitly uttered to Frankenstein. Third, it has been checked how the medical and scientific development is related to the main issues of mechanism and vitalism which can be explained as principles of life. Even though this research deals with the developmental process of medicine & science and origin & principles of life implied in Mary Shelley's Frankenstein, its significance is that it is the interdisciplinary research focussing on how deeply medical and scientific discourse of Mary Shelley's period has been imbedded in the nineteenth century novel.

    The Lunar Workshops for Educators (LWE) series was developed by the Lunar Reconnaissance Orbiter (LRO) education team in 2010 to provide professional development on lunar science and exploration concepts for grades 6-9 science teachers. Over 300 educators have been trained to date. The LWE model incorporates best practices from pedagogical research of science education, thoughtful integration of scientists and engineer subject matter experts for both content presentations and informal networking with educators, access to NASA-unique facilities, hands-on and data-rich activities aligned with education standards, exposure to the practice of science, tools for addressing common misconceptions, follow-up with participants, and extensive evaluation. Evaluation of the LWE model via pre- and post-assessments, daily workshop surveys, and follow-up surveys at 6-month and 1-year intervals indicate that the LWE are extremely effective in increasing educators' content knowledge, confidence in incorporating content into the classroom, understanding of the practice of science, and ability to address common student misconceptions. In order to address the efficacy of the LWE model for other science content areas, the Dynamic Response of Environments at Asteroids, the Moon, and moons of Mars (DREAM2) education team, funded by NASA's Solar System Exploration Research Virtual Institute, developed and ran a pilot workshop called Dream2Explore at NASA's Goddard Space Flight Center in June, 2015. Dream2Explore utilized the LWE model, but incorporated content related to the science and exploration of asteroids and the moons of Mars. Evaluation results indicate that the LWE model was effectively used for educator professional development on non-lunar content. We will present more detail on the LWE model, evaluation results from the Dream2Explore pilot workshop, and suggestions for the application of the model with other science content for robust educator professional development.

    A software framework called PCS Task Wrapper is responsible for standardizing the setup, process initiation, execution, and file management tasks surrounding the execution of science data algorithms, which are referred to by NASA as Product Generation Executives (PGEs). PGEs codify a scientific algorithm, some step in the overall scientific process involved in a mission science workflow. The PCS Task Wrapper provides a stable operating environment to the underlying PGE during its execution lifecycle. If the PGE requires a file, or metadata regarding the file, the PCS Task Wrapper is responsible for delivering that information to the PGE in a manner that meets its requirements. If the PGE requires knowledge of upstream or downstream PGEs in a sequence of executions, that information is also made available. Finally, if information regarding disk space, or node information such as CPU availability, etc., is required, the PCS Task Wrapper provides this information to the underlying PGE. After this information is collected, the PGE is executed, and its output Product file and Metadata generation is managed via the PCS Task Wrapper framework. The innovation is responsible for marshalling output Products and Metadata back to a PCS File Management component for use in downstream data processing and pedigree. In support of this, the PCS Task Wrapper leverages the PCS Crawler Framework to ingest (during pipeline processing) the output Product files and Metadata produced by the PGE. The architectural components of the PCS Task Wrapper framework include PGE Task Instance, PGE Config File Builder, Config File Property Adder, Science PGE Config File Writer, and PCS Met file Writer. This innovative framework is really the unifying bridge between the execution of a step in the overall processing pipeline, and the available PCS component services as well as the information that they collectively manage.

  20. Using Art to Enhance the Learning of Math and Science: Developing an Educational Art-Science Kit about Fractal Patterns in Nature

    Science.gov (United States)

    Rao, Deepa

    This study documents the development of an educational art-science kit about natural fractals, whose aim is to unite artistic and scientific inquiry in the informal learning of science and math. Throughout this research, I argue that having an arts-integrated approach can enhance the learner of science and math concepts. A guiding metaphor in this thesis is the Enlightenment-era cabinet of curiosities that represents a time when art and science were unified in the process of inquiry about the natural world. Over time, increased specialization in the practice of arts and science led to a growing divergence between the disciplines in the educational system. Recently, initiatives like STEAM are underway at the national level to integrate "Arts and Design" into the Science, Technology, Engineering, and Math (STEM) formal education agenda. Learning artifacts like science kits present an opportunity to unite artistic and scientific inquiry in informal settings. Although science kits have been introduced to promote informal learning, presently, many science kits have a gap in their design, whereby the activities consist of recipe-like instructions that do not encourage further inquiry-based learning. In the spirit of the cabinet of curiosities, this study seeks to unify visual arts and science in the process of inquiry. Drawing from educational theories of Dewey, Piaget, and Papert, I developed a novel, prototype "art-science kit" that promotes experiential, hands-on, and active learning, and encourages inquiry, exploration, creativity, and reflection through a series of art-based activities to help users learn science and math concepts. In this study, I provide an overview of the design and development process of the arts-based educational activities. Furthermore, I present the results of a pilot usability study (n=10) conducted to receive user feedback on the designed materials for use in improving future iterations of the art-science fractal kit. The fractal kit

  1. Paradigms of forensic science and legal process: a critical diagnosis.

    Roberts, Paul

    2015-08-05

    This article reconsiders the relationship between criminal adjudication and forensic expertise in the light of 'new paradigms' of forensic practice and recent law reform. It briefly summarizes conventional wisdom on the typical shortcomings of forensic science and other expert evidence, as a springboard for a more searching critical diagnosis of longstanding maladies. The fundamentally jurisdictional nature of law is emphasized, and some implications for expert testimony noted. English law's traditionally adversarial model of criminal procedure is then reassessed, taking account of a proper understanding of its normative structure and modern development, and drawing on comparative legal research and theorizing to obtain a more rounded second opinion. In conclusion, some avenues for intelligent prescription are canvassed, highlighting the importance of promoting and facilitating effective communication between experts, lawyers and courts, and prioritizing modest practical remedies over radical surgery. © 2015 The Author(s) Published by the Royal Society.

    Steponas Kolupaila (1892-1964) was an important figure in 20th century hydrology and one of the pioneers of scientific water gauging in Europe. His research on the reliability of hydrological data and measurement methods was particularly important and contributed to the development of empirical hydrological calculation methods. Kolupaila was one of the first who standardised water-gauging methods internationally. He created several original hydrological and hydraulic calculation methods (his discharge assessment method for winter period was particularly significant). His innate abilities and frequent travel made Kolupaila a universal specialist in various fields and an active public figure. He revealed his multilayered scientific and cultural experiences in his most famous book, Bibliography of Hydrometry. This book introduced the unique European hydrological-measurement and computation methods to the community of world hydrologists at that time and allowed the development and adaptation of these methods across the world.

  4. Learning Science Process Through Data Exploration and Writing

    Science.gov (United States)

    Prothero, W. A.

    2007-12-01

    One of the most effective ways of teaching science process is to have students take part in the same activities that practicing scientists engage in. These activities include studying the current research in the field, discussing ideas with colleagues, formulating a research problem, making a proposal defining the problem and plan of attack, presenting and writing about the results of the study, and critically reviewing the work of others. An inquiry curriculum can use these activities to guide the scaffolding of assignments and learning experiences that help students learn science process. At UCSB, students in a large general education oceanography class use real Earth data to study plate tectonics, the Indian Monsoon, climate change, and the health of the world fisheries. The end product for each subject has been a science paper based on Earth data. Over a period of approximately 15 years, the scaffolding of activities to prepare each student for the written assignments has been modified and improved, in response to student feedback and their success with the assignments. I have found that the following resources and sequence of activities help the oceanography students write good science papers. 1. Lecture: motivation and the opportunity for feedback and questions. 2. Textbook: background information. It is also possible to get the information from the internet, but unless the scope of reading is strictly defined, students don't know when to stop reading and become unhappy. 3. Online assignments: automatically graded assignments that force the student to keep up with reading. 4. Questions of the day: in-class handouts, with diagrams that the students either complete, or answer questions about. They are handed in and tallied, but not graded. They also inform the instructor of misconceptions. 5. Thought questions: student answers are posted on a threaded discussion list, and are due prior to lecture. The answers provide instructor feedback and guide the lecture

    Gaseous diffusion has so far been the main source of supply for enriched uranium and it is only recently that the gas centrifuge came into the picture. Numerous other isotope separation processes have been considered or are being assessed, and there is nothing to exclude the future use of a new process. Developments on likely new processes have been carried out by many organizations both governmental and private. The French Commissariat a l'energie atomique, besides their very extensive endeavours already devoted to gaseous diffusion, have studied and developed the gas centrifuge, chemical exchange, aerodynamic and selective photoexcitation processes. The gaseous diffusion process, selected by Eurodif for the Tricastin plant, and which will also be used by Coredif, is discussed in another paper in these Proceedings. This process is the technico-economic yardstick on which our comparisons are based. Within the limits of their development level, processes are compared on the basis of the separative work cost components: specific investment, specific power consumption and power cost, and specific operating and maintenance costs.

    1997-01-01

    Our overall purpose for this multi-year project was to develop an alternative assessment format measuring rural middle school students understanding of science concepts and processes and the interrelationships among them. This kind of understanding is called structural knowledge. We had 3 major interrelated goals: (1) Synthesize the existing literature and critically evaluate the actual and potential use of measures of structural knowledge in science education. (2) Develop a structural knowledge alternative assessment format. (3) Examine the validity of our structural knowledge format. We accomplished the first two goals during year 1. The structural knowledge assessment we identified and developed further was a select-and-fill-in concept map format. The goal for our year 2 work was to begin to validate this assessment approach. This final report summarizes our year 2 work.

  8. Integrated durability process in product development

    International Nuclear Information System (INIS)

    Pompetzki, M.; Saadetian, H.

    2002-01-01

    This presentation describes the integrated durability process in product development. Each of the major components of the integrated process are described along with a number of examples of how integrated durability assessment has been used in the ground vehicle industry. The durability process starts with the acquisition of loading information, either physically through loads measurement or virtually through multibody dynamics. The loading information is then processed and characterized for further analysis. Durability assessment was historically test based and completed through field or laboratory evaluation. Today, it is common that both the test and CAE environments are used together in durability assessment. Test based durability assessment is used for final design sign-off but is also critically important for correlating CAE models, in order to investigate design alternatives. There is also a major initiative today to integrate the individual components into a process, by linking applications and providing a framework to communicate information as well as manage all the data involved in the entire process. Although a single process is presented, the details of the process can vary significantly for different products and applications. Recent applications that highlight different parts of the durability process are given. As well as an example of how integration of software tools between different disciplines (MBD, FE and fatigue) not only simplifies the process, but also significantly improves it. (author)

    As oil deposits are limited, it is very important to develop techniques for manufacturing petroleum alternatives as substitute energy sources to brighten the outlook for the future. The Research Association for Petroleum Alternatives Development (RAPAD) in Japan is engaged in the research and development of production techniques for light hydrocarbon oils such as gasoline, kerosene, and light oil from synthesis gas (CO, H/sub 2/) obtained from the raw materials of natural gas, coal, etc. Regarding the MTG process of synthesizing gasoline via methanol from synthesis gas and the STG process of directly synthesizing gasoline from synthesis gas, Cosmo Oil Co., Ltd. and Mitsubishi Heavy Industries, Ltd., members of RAPAD, have sought jointly to develop catalysts and processes. As a result of this co-operation, the authors have recently succeeded in developing a new catalyst with a long life span capable of providing a high yield and high selectivity. Additionally, the authors are currently on the verge of putting into effect a unique two-step STG process of synthesizing high octane gasoline via dimethyl ether, referred to as the AMSTG process.

  10. Professional development and poststructural analysis: Stories of African-American science teachers

    Science.gov (United States)

    Moore, Felicia Michelle

    2003-10-01

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

    ATP's Mission and Operations. The ATP partners with industry to accelerate the development of innovative technologies for broad national economic benefit. The program's focus is on co-funding collaborative, multi-disciplinary technologies and enabling technology platforms that appear likely to be commercialized, with private sector funding, once the high technical risks are reduced. Industry-led projects are selected for funding in rigorous competitions on the basis of technical and economic merit. Since 1990, ATP has co-funded 642 projects, with 1,329 participants and another 1,300 subcontractors. Measuring to Mission: Overview of ATP's Evaluation Program. ATP's multi-component evaluation strategy provides measures of progress and performance matched to the stage of project evolution; i.e., for the short-term, from the time of project selection and over the course of the R for the mid-term, as commercial applications are pursued, early products reach the market, and dissemination of knowledge created in the R projects occurs; and for the longer-term, as more fully-developed technologies diffuse across multiple products and industries. The approach is applicable to all public S programs and adaptable to private or university projects ranging from basic research to applied industrial R. Examples of Results. ATP's composite performance rating system assesses ATP's completed projects against multi-faceted performance criteria of Knowledge Creation and Dissemination and Commercialization Progress 2-3 years after the end of ATP-funded R. It generates scores ranging from zero to four stars. Results for ATP's first 50 completed projects show that 16are in the bottom group of zero or one stars. 60the middle group. It is understood that not all ATP projects will be successful given the program's emphasis on funding high-risk technology development that the private sector is unwilling and unable to fund alone.

    1982-01-01

    In the field of nuclear experiments, the speed-up of data processing has been required recently along with the increase of the amount of data per event or the rate of event occurrence per unit time. In the DUMAS project of RCNP, the development of data processing system has been required, which can perform the high speed transfer and processing. The system should transfer the data of 5 multiwire proportional counters and other counters from the laboratory to the counting room at the rate of 1000 events every second, and also should perform considerably complex processes such as histogramming, particle identification, calculation of various polarizations as well as dumping to the secondary memory in the counting room. Furthermore, easy start-up, adjustment, inspection and maintenance and non-special hardware and software should be considered. A system presently being investigated for satisfying the above requirements is described. The main points are as follows: to employ CAMAC system for the interface with readout circuit, to transfer data between the laboratory and the counting room by converting the byte-serial transfer to the bit-serial optical fiber communication, and to unify the data processing computers to the PDP-11 family by connecting two miniature computers. Development of such a data processing system seems to be useful as an preparatory research for the development of NUMATRON measuring instruments. (Wakatsuki, Y.)

    The increased popularity of mobile phone apps provide scientists with a new avenue for sharing and distributing data and knowledge with colleagues, while also providing meaningful education and outreach products for consumption by the general public. Our initial development of iPhone and Android apps centered on the distribution of exciting auroral images taken at the South Pole for education and outreach purposes. These portable platforms, with limited resources when compared to computers, presented a unique set of design and implementation challenges that we will discuss in this presentation. For example, the design must account for limited memory; screen size; processing power; battery life; and potentially high data transport costs. Some of these unique requirements created an environment that enabled undergraduate and high-school students to participate in the creation of these apps. Additionally, during development it became apparent that these apps could also serve as data analysis and engineering tools. Our presentation will further discuss our plans to use apps not only for Education and Public Outreach, but for teaching, science and engineering.

    Coal partial hydropyrolysis process aims at co-production of high yield of light oil such as BTX and naphthalene and synthesis gas from a low rank coal under a mild hydropyrolysis condition. The characteristic of this process is in the two-staged entrained hydropyrolysis reactor composed of the reformer and gasifier. This reactor arrangement gives us high heat efficiency of this process. So far, in order to evaluate the process concept a small-scale basic experiment and a 1t/day process development unit study were carried out. The experimental results showed that coal volatiles were partially hydrogenated to increase the light oil and hydrocarbon gases at the condition of partial hydropyrolysis such as pressure of 2-3MPa, temperature of 700-900{sup o}C and hydrogen concentration of 30-50%. This process has a possibility of producing efficiently and economically liquid and gas products as chemicals and fuel for power generation. As a further development in the period of 2003 to 2008, a 20t/day pilot plant study named ECOPRO (efficient co-production with coal flash hydropyrolysis technology) has been started to establish the process technologies for commercialization. 12 refs., 6 figs., 3 tabs.

    Since nearly 30 years, many european studies have demonstrated a worrying decline of young people's interest in science and technical studies. Despite the number of efforts and programs made to reverse the trend, there are still few signs of improvement. We must step up our efforts otherwise this will impact the long-term innovation capacities of our country. We have tried to participate to these efforts with the creation of a digital and interactive comics "2101, Science & Fiction", created by Chromatiques, that explores the connections between reality of science and science fiction. It takes advantage of the new opportunities opened by digital technology and is another way of developing interest in learning sciences. Free access on: http://2101.fr The goal is to create an new opportunity to popularize science and attract the young generation in different fields of technology and science.

    The twin Mars Exploration Rovers (MER) delivered an unprecedented array of image sensors to the Mars surface. These cameras were essential for operations, science, and public engagement. The Multimission Image Processing Laboratory (MIPL) at the Jet Propulsion Laboratory was responsible for the first-order processing of all of the images returned by these cameras. This processing included reconstruction of the original images, systematic and ad hoc generation of a wide variety of products derived from those images, and delivery of the data to a variety of customers, within tight time constraints. A combination of automated and manual processes was developed to meet these requirements, with significant inheritance from prior missions. This paper describes the image products generated by MIPL for MER and the processes used to produce and deliver them.

    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.

    "Water in the Solar System" is an out-of-school time (OST) science education activity for middle school students that was developed as part of the Planetary Learning that Advances the Nexus of Engineering, Technology, and Science (PLANETS) project. The PLANETS project was selected in support of the NASA Science Mission Directorate's Science Education Cooperative Agreement Notice, with the goal of developing and disseminating OST curriculum and related professional development modules that integrate planetary science, technology, and engineering. "Water in the Solar System" is a science activity that addresses the abundance and availability of water in the solar system. The activity consists of three exercises based on the following guiding questions: 1) How much water is there on the Earth? 2) Where can you find water in the solar system? and 3) What properties affect whether or not water can be used by astronauts? The three exercises involve a scaling relationship demonstration about the abundance of useable water on Earth, a card game to explore where water is found in the solar system, and a hands-on exercise to investigate pH and salinity. Through these activities students learn that although there is a lot of water on Earth, most of it is not in a form that is accessible for humans to use. They also learn that most water in the solar system is actually farther from the sun, and that properties such as salinity and pH affect whether water can be used by humans. In addition to content for students, the activity includes background information for educators, and links to in-depth descriptions of the science content. "Water in the Solar System" was developed through collaboration between subject matter experts at the USGS Astrogeology Science Center, and curriculum and professional development experts in the Center for Science Teaching and Learning at Northern Arizona University. Here we describe our process of curriculum development, education objectives of

  9. Development of a Bi-Disciplinary Course in Forensic Science

    Stacey L. Raimondi

    2013-08-01

    Full Text Available Forensic science programs and courses have traditionally been housed within chemistry departments at the college/university level, largely because the pioneers of the field were chemists who applied technology that was more chemical than biological in nature. However, with the development of such areas of study as DNA analysis, anatomical studies, and forensic entomology, it is becoming more and more important for forensic science students to have a strong biological background as well as a chemical background. Furthermore, while biology students are typically required to have extensive chemistry training as part of their major, the converse is not true for chemistry students. Therefore, it is possible that a student interested in forensic science could complete a major in chemistry and never have taken a biology class, leaving them woefully under-prepared for any type of masters program or career in forensic science immediately following graduation. Indeed, an examination of available positions in forensic science shows a large number of positions for DNA analysts for which the typical chemistry student would not be prepared without extensive biology training (http://www.aafs.org. Furthermore, positions for medical examiners or pathologists require extensive training in biology in addition to the continued medical training and residency programs. Therefore, it seems imperative that introductory forensic science courses adapt to these needs and be taught with a more bi-disciplinary approach in order to educate students on the whole field rather than one aspect. To that end, a new bi-disciplinary Forensic Science course was developed at Elmhurst College. This course was team-taught by a biology and a chemistry professor so that students would obtain a thorough understanding of the field and techniques used by both biologists and chemists. A description of this new version of a forensic science course follows, focusing on the addition of biology

  18. The Use of the Evidence from the Behavioral Sciences in the Organizational Decision-Making Process

    Directory of Open Access Journals (Sweden)

    Bogdan MÎNJINĂ

    2015-09-01

    Full Text Available The important managerial decision-making and the development of policies, strategies, internal normative acts and procedures must be solid grounded for efficient achieving of their objectives. To this end, the evidence-based approach uses various types of evidence, a leading role having those scientific, and the critical thinking. The evidence from behavioral sciences is especially important when the decisions objectives involve behavioral elements. They also help to ensure the rationality of any decision-making process. The concern for the use of behavioral sciences research in the decision-making preceded the occurrence of evidence-based approach. The increased knowledge fund of organizations, the access to the best practices and to the relevant scientific research findings represent only the initial stages of the evidence-based approach implementation and functioning. The ensuring of their effective use calls for special skills training among staff, the creation of tools and organizational mechanisms and of a facilitating organizational culture. This paper argues the need to integrate two approaches that promote the decision-making based on scientific evidence, the evidence-based approach and the use of behavioral and social sciences in the decision-making, to potentiate the contribution of the behavioral sciences to the increasing of the decision-making efficiency. The efforts made in this paper had overall objective to prepare and facilitate the use of research evidence provided by behavioral sciences in the organizational decision-making process by presenting the main concepts and knowledge in the field and by proposing an outline procedure specifically developed.

  19. Examining Science Teachers' Development of Interdisciplinary Science Inquiry Pedagogical Knowledge and Practices

    Chowdhary, Bhawna; Liu, Xiufeng; Yerrick, Randy; Smith, Erica; Grant, Brooke

    2014-12-01

    The current literature relates to how teachers develop knowledge and practice of science inquiry, but little has been reported on how teachers develop interdisciplinary science inquiry (ISI) knowledge and practice. This study examines the effect of university research experiences, ongoing professional development, and in-school support on teachers' development of ISI pedagogical knowledge and practices. It centers on documenting diverse teachers' journeys of experiencing ISI as well as developing knowledge of ISI. It was found that there was variation in ISI understanding and practice among the teachers as a result of the combination of teachers' experiences, beliefs, and participation. Thus, in order to help teachers develop ISI knowledge and pedagogy, barriers to ISI knowledge development and implementation must also be addressed. Professional developers must articulate clear program goals to all stakeholders including an explicit definition of ISI and the ability to recognize ISI attributes during research experiences as well as during classroom implementation. Teachers must also be held accountable for participation and reflection in all aspects of professional development. Program developers must also take into consideration teachers' needs, attitudes, and beliefs toward their students when expecting changes in teachers' cognition and behavior to teach inquiry-rich challenging science.

    2015-12-01

    The Sustainable Development Goals are underpinned by a committment to a world that is just, equitable, inclusive and environmentally sustainable and include goals of ending poverty and hunger; universal access to health, education, water, sanitation, energy and decent work; and reducing the risks and impacts of climate change, biodiversity loss, and marine, forest and land degradation. They seek to reduce inequality between and within countries and achieve gender equality. The SDGs build on the apparent success in meeting many of the Millenium Development Goals, including those of reducing poverty, hunger and debt and providing access to water. The science needed to achieve and monitor most of these goals is social science - an area of scholarship that is traditionally undervalued, underfunded, underepresented misunderstood and lacking in detailed data. This paper will provide an overview of the social science that is needed to support the Sustainable Development Goals, with a particular focus on the challenges of monitoring social data over time and within countries, the importance of research design, and of building capacity and credibility in the social sciences. As an example, the paper will discuss the social science that will be needed to achieve Goal 13: Take urgent actions to combat climate change and its impacts, and measuring targets such as strengthening resilience and adaptive capacity, and raising capacities of women, youth, and marginalized communities to manage and respond climate change.

  1. [Twisting and turning; the development of the Dutch science shops].

    Lursen, M; Mulder, H; Lieshout, M

    2000-01-01

    The concept of science shops (Wetenschapswinkels) originates from the Netherlands. Science shops were based on the idea that universities had to play a more prominent role in the solution of social problems - an outcome of the discussion, initiated by students, on the democratisation of universities in the early 1970s. Starting as voluntary student organisations supported by individual staff members from the universities, they were devoted to give oppressed minority groups and the financially weak access to scientific research. Slowly, acknowledgement came. Science shops began to receive financial support from university boards. Support also came from the Dutch government. By now science shops have professionalized and most of them are well embedded in their universities. Many developments within society and the universities influenced the work and structure of the science shops. Positive developments were professionalization, growth, becoming embedded, and the introduction of new research themes. There were also negative developments, such as budget cuts and the fact that 'service to society' ceased to be a government objective for the universities. These led to recurring struggles for survival, which were not always won. Interest in the science shop concept has grown in other countries over the last years. In the 1980s, the system spread within Western Europe. Similar activities, based on the Dutch model, have started in North America and Eastern Europe in the 1990s. The activities on the international level led to an E.U. financial project to prepare an international network of science shops, which commenced in 1999. With information exchange and international cooperation as its major goals, the network will create new opportunties for the future.

  2. Teaching the process of science: faculty perceptions and an effective methodology.

    Science.gov (United States)

    2010-01-01

    Most scientific endeavors require science process skills such as data interpretation, problem solving, experimental design, scientific writing, oral communication, collaborative work, and critical analysis of primary literature. These are the fundamental skills upon which the conceptual framework of scientific expertise is built. Unfortunately, most college science departments lack a formalized curriculum for teaching undergraduates science process skills. However, evidence strongly suggests that explicitly teaching undergraduates skills early in their education may enhance their understanding of science content. Our research reveals that faculty overwhelming support teaching undergraduates science process skills but typically do not spend enough time teaching skills due to the perceived need to cover content. To encourage faculty to address this issue, we provide our pedagogical philosophies, methods, and materials for teaching science process skills to freshman pursuing life science majors. We build upon previous work, showing student learning gains in both reading primary literature and scientific writing, and share student perspectives about a course where teaching the process of science, not content, was the focus. We recommend a wider implementation of courses that teach undergraduates science process skills early in their studies with the goals of improving student success and retention in the sciences and enhancing general science literacy.

  5. K-5 mentor teachers' journeys toward reform-oriented science within a professional development school context

    Science.gov (United States)

    Manno, Jacqueline L.

    Reform-oriented science teaching with a specific focus on evidence and explanation provides a student-centered learning environment which encourages children to question, seek answers to those questions, experience phenomena, share ideas, and develop explanations of science concepts based on evidence. One of the ways schools have risen to meet the challenge of ever-increasing demands for success in science and all other curricular areas has been in the development of professional development schools (PDSs). Dedicated to the simultaneous renewal of schools and teacher education programs, the structure of a PDS plays a significant role in the change process. The purpose of this research study was to investigate the nature of change in mentor teachers' beliefs and pedagogical practices toward science teaching in the elementary school as conveyed through their own "stories of practice". The major research questions that guided the study were: (1) How do mentor teachers describe their science teaching practices and how have they changed as a result of participation in PDS? (a) In what ways do PDS mentor teachers' descriptions of practice reflect contemporary reform ideas and practices in science education? (b) To what extent do their stories emphasize technical aspects of teaching versus epistemological changes in their thinking and knowledge? (c) How is student learning in science reflected in teachers' stories of practice? (2) What is the relationship between the levels and types of involvement in PDS to change in thinking about and practices of teaching science? (3) What is the depth of commitment that mentors convey about changes in science teaching practices? Using case study design, the research explored the ways experienced teachers, working within the context of a PDS community, described changes in the ways they think about and teach science. The connection to the issue of change in teaching practices grew out of interest in understanding the relationship

    Research at Virginia Tech led to the development of two complementary concepts for improving the removal of inorganic sulfur from many eastern U.S. coals. These concepts are referred to as Electrochemically Enhanced Sulfur Rejection (EESR) and Polymer Enhanced Sulfur Rejection (PESR) processes. The EESR process uses electrochemical techniques to suppress the formation of hydrophobic oxidation products believed to be responsible for the floatability of coal pyrite. The PESR process uses polymeric reagents that react with pyrite and convert floatable middlings, i.e., composite particles composed of pyrite with coal inclusions, into hydrophilic particles. These new pyritic-sulfur rejection processes do not require significant modifications to existing coal preparation facilities, thereby enhancing their adoptability by the coal industry. It is believed that these processes can be used simultaneously to maximize the rejection of both well-liberated pyrite and composite coal-pyrite particles. The project was initiated on October 1, 1992 and all technical work has been completed. This report is based on the research carried out under Tasks 2-7 described in the project proposal. These tasks include Characterization, Electrochemical Studies, In Situ Monitoring of Reagent Adsorption on Pyrite, Bench Scale Testing of the EESR Process, Bench Scale Testing of the PESR Process, and Modeling and Simulation.

    Nelms, April Wagnon

    This dissertation used qualitative methodologies, specifically phenomenological research, to investigate what contributes to the development of pedagogical content knowledge (PCK) of physics and physical science teachers who participate in a content-specific continuous professional development program. There were five participants in this study. The researcher conducted participant observations and interviews, rated participants degree of reformed teaching practices using the Reformed Teaching Observation Protocol, surveyed participants' self-efficacy beliefs using the Science Teacher Efficacy Belief Instrument "A," and rated participants'' level of PCK using the PCK Rubrics.. All data were analyzed, and a composite description of what contributes to physics and physical science teachers' PCK development through a continuous professional development program emerged. A theory also emerged from the participants' experiences pertaining to how teachers' assimilate new conditions into their existing teaching schema, how conditions change teachers' perceptions of their practice, and outcomes of teachers' new ideas towards their practice. This study contributed to the literature by suggesting emergent themes and a theory on the development of physics and physical science teachers' PCK. PCK development is theorized to be a spiral process incorporating new conditions into the spiral as teachers employ new science content knowledge and pedagogical practices in their individual classroom contexts.

    A novel process was developed for converting scum, a waste material from wastewater treatment facilities, to biodiesel. Scum is an oily waste that was skimmed from the surface of primary and secondary settling tanks in wastewater treatment plants. Currently scum is treated either by anaerobic digestion or landfilling which raised several environmental issues. The newly developed process used a six-step method to convert scum to biodiesel, a higher value product. A combination of acid washing and acid catalyzed esterification was developed to remove soap and impurities while converting free fatty acids to methyl esters. A glycerol washing was used to facilitate the separation of biodiesel and glycerin after base catalyzed transesterification. As a result, 70% of dried and filtered scum was converted to biodiesel which is equivalent to about 134,000 gallon biodiesel per year for the Saint Paul waste water treatment plant in Minnesota.

    2015-11-01

    Full Text Available The aim of the article is to analyze the world experience in using education and science in the processes of increasing the intellectual potential of the state and prospects of its application in Ukraine. The article describes features of the continental, Atlantic and the East Asian models of higher education management with emphasis on the key points, which can be useful for reforming the Ukrainian system of education. It has been noted that the problem of higher education quality in Ukraine lies in fundamental principles of its functioning, because development of the national education system for a long time took place under conditions of administrative system, while the European system of education is built on principles of competition and free market. On the basis of comparative characteristics of sources of finance in the United States there has been determined a dominant role of the federal government and it has been found that among the branches of science the leading positions are occupied by the life sciences. The experience of reforming science in countries of the Central and Eastern Europe, which took place on the model of functioning of the research institutes and research process in the EU countries, has been analyzed. Particular attention is paid to the successful experience of reforming the education and science in China. Taking into account the international experience the author has substantiated the directions of increasing the intellectual potential in Ukraine by deepening the integration of education and science, in particular: the creation of a wide network of research universities and conducting of a fair share of fundamental research on their base; accelerated development of public-private partnership in education and science; quick updating of the curricula adequate to the requirements of time and introduction of interdisciplinary courses; competitive financing of scientific programs with participation of the state and

    Beyon, Jeffrey Y.; Ng, Tak-Kwong; Lin, Bing; Hu, Yongxiang; Harrison, Wallace

    2014-01-01

    A new development of on-board data processing platform has been in progress at NASA Langley Research Center since April, 2012, and the overall review of such work is presented in this paper. The project is called High-Speed On-Board Data Processing for Science Instruments (HOPS) and focuses on a high-speed scalable data processing platform for three particular National Research Council's Decadal Survey missions such as Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS), Aerosol-Cloud-Ecosystems (ACE), and Doppler Aerosol Wind Lidar (DAWN) 3-D Winds. HOPS utilizes advanced general purpose computing with Field Programmable Gate Array (FPGA) based algorithm implementation techniques. The significance of HOPS is to enable high speed on-board data processing for current and future science missions with its reconfigurable and scalable data processing platform. A single HOPS processing board is expected to provide approximately 66 times faster data processing speed for ASCENDS, more than 70% reduction in both power and weight, and about two orders of cost reduction compared to the state-of-the-art (SOA) on-board data processing system. Such benchmark predictions are based on the data when HOPS was originally proposed in August, 2011. The details of these improvement measures are also presented. The two facets of HOPS development are identifying the most computationally intensive algorithm segments of each mission and implementing them in a FPGA-based data processing board. A general introduction of such facets is also the purpose of this paper.

    2014-04-01

    Contemporary research into science education has generally been conducted from the perspective of 'conceptual change' in learning. This study sought to extend previous work by recognizing that human rationality can be influenced by the emotions generated by the learning environment and specific actions related to learning. Methods used in educational psychology were adopted to investigate the emotional experience of science students as affected by gender, teaching methods, feedback, and learning tasks. A multidisciplinary research approach combining brain activation measurement with multivariate psychological data theory was employed in the development of a questionnaire intended to reveal the academic emotions of university students in three situations: attending science class, learning scientific subjects, and problem solving. The reliability and validity of the scale was evaluated using exploratory and confirmatory factor analyses. Results revealed differences between the genders in positive-activating and positive-deactivating academic emotions in all three situations; however, these differences manifested primarily during preparation for Science tests. In addition, the emotions experienced by male students were more intense than those of female students. Finally, the negative-deactivating emotions associated with participation in Science tests were more intense than those experienced by simply studying science. This study provides a valuable tool with which to evaluate the emotional response of students to a range of educational situations.

    The 20th mission of the National Aeronautics and Space Administration (NASA) Extreme Environment Mission Operations (NEEMO) was a highly integrated evaluation of operational protocols and tools designed to enable future exploration beyond low-Earth orbit. NEEMO 20 was conducted from the Aquarius habitat off the coast of Key Largo, FL in July 2015. The habitat and its surroundings provide a convincing analog for space exploration. A crew of six (comprised of astronauts, engineers, and habitat technicians) lived and worked in and around the unique underwater laboratory over a mission duration of 14-days. Incorporated into NEEMO 20 was a diverse Science Team (ST) comprised of geoscientists from the Astromaterials Research and Exploration Science (ARES/XI) Division from the Johnson Space Center (JSC), as well as marine scientists from the Department of Biological Sciences at Florida International University (FIU). This team trained the crew on the science to be conducted, defined sampling techniques and operational procedures, and planned and coordinated the science focused Extra Vehicular Activities (EVAs). The primary science objectives of NEEMO 20 was to study planetary sampling techniques and tools in partial gravity environments under realistic mission communication time delays and operational pressures. To facilitate these objectives two types of science sites were employed 1) geoscience sites with available rocks and regolith for testing sampling procedures and tools and, 2) marine science sites dedicated to specific research focused on assessing the photosynthetic capability of corals and their genetic connectivity between deep and shallow reefs. These marine sites and associated research objectives included deployment of handheld instrumentation, context descriptions, imaging, and sampling; thus acted as a suitable proxy for planetary surface exploration activities.

  20. The Systems Engineering Process for Human Support Technology Development

    Jones, Harry

    2005-01-01

    Systems engineering is designing and optimizing systems. This paper reviews the systems engineering process and indicates how it can be applied in the development of advanced human support systems. Systems engineering develops the performance requirements, subsystem specifications, and detailed designs needed to construct a desired system. Systems design is difficult, requiring both art and science and balancing human and technical considerations. The essential systems engineering activity is trading off and compromising between competing objectives such as performance and cost, schedule and risk. Systems engineering is not a complete independent process. It usually supports a system development project. This review emphasizes the NASA project management process as described in NASA Procedural Requirement (NPR) 7120.5B. The process is a top down phased approach that includes the most fundamental activities of systems engineering - requirements definition, systems analysis, and design. NPR 7120.5B also requires projects to perform the engineering analyses needed to ensure that the system will operate correctly with regard to reliability, safety, risk, cost, and human factors. We review the system development project process, the standard systems engineering design methodology, and some of the specialized systems analysis techniques. We will discuss how they could apply to advanced human support systems development. The purpose of advanced systems development is not directly to supply human space flight hardware, but rather to provide superior candidate systems that will be selected for implementation by future missions. The most direct application of systems engineering is in guiding the development of prototype and flight experiment hardware. However, anticipatory systems engineering of possible future flight systems would be useful in identifying the most promising development projects.

  1. Developing science policy capacity at the state government level: Planning a science and technology policy fellowship program for Colorado and beyond

    2017-12-01

    There is growing recognition of the potential to advance science policy capacity within state legislatures, where there is most often a shortage of professional backgrounds in the natural sciences, technology, engineering, and medicine. Developing such capacity at the state level should be considered a vital component of any comprehensive national scale strategy to strengthen science informed governance. Toward this goal, the Center for Science and Technology Policy Research at the University of Colorado Boulder is leading a strategic planning process for a Science and Technology Policy Fellowship Program within the Colorado state legislature and executive branch agencies. The intended program will place PhD-level scientists and engineers in one-year placements with decision-makers to provide an in-house resource for targeted policy-relevant research. Fellows will learn the intricacies of the state policymaking process, be exposed to opportunities for science to inform decisions, and develop a deeper understanding of key science and technology topics in Colorado, including water resources, wildfire management, and energy. The program's ultimate goals are to help foster a decision-making arena informed by evidence-based information, to develop new leaders adept at bridging science and policymaking realms, and to foster governance that champions the role of science in society. Parallel to efforts in Colorado, groups from nine other states are preparing similar plans, providing opportunities to share approaches across states and to set the stage for increased science and technology input to state legislative agendas nationwide. Importantly, highly successful and sustainable models exist; the American Association for the Advancement of Science (AAAS) has implemented a federally based fellowship program for over 43 years and the California Council for Science and Technology (CCST) has directed a fellowship program for their state's legislature since 2009.

    2012-03-01

    Multiple process approaches have been used historically to manufacture cylindrical nuclear fuel compacts. Scale-up of fuel compacting was required for the Next Generation Nuclear Plant (NGNP) project to achieve an economically viable automated production process capable of providing a minimum of 10 compacts/minute with high production yields. In addition, the scale-up effort was required to achieve matrix density equivalent to baseline historical production processes, and allow compacting at fuel packing fractions up to 46% by volume. The scale-up approach of jet milling, fluid-bed overcoating, and hot-press compacting adopted in the U.S. Advanced Gas Reactor (AGR) Fuel Development Program involves significant paradigm shifts to capitalize on distinct advantages in simplicity, yield, and elimination of mixed waste. A series of compaction trials have been completed to optimize compaction conditions of time, temperature, and forming pressure using natural uranium oxycarbide (NUCO) fuel at packing fractions exceeding 46% by volume. Results from these trials are included. The scale-up effort is nearing completion with the process installed and operable using nuclear fuel materials. Final process testing is in progress to certify the process for manufacture of qualification test fuel compacts in 2012.

    Currently, the economic advantage of any known approach to the back end fuel cycle of a nuclear power reactor has not been well established. Thus the long term storage of the spent fuel in a safe manner is one of the important issues to be resolved in countries where the nuclear power has a relatively heavy weight in power production of that country. At KAERI, as a solution to this particular issue midterm storage of the spent fuel, an alternative approach has been developed. This approach includes the decladding and pulverization process of the spent PWR fuel rod, the reducing process from the uranium oxide to a metallic uranium powder using Li metal in a LiCl salt, the continuous casting process of the reduced metal, and the recovery process of Li from mixed salts by the electrolysis. We conducted the laboratory scale tests of each processes for the technical feasibility and determination for the operational conditions for this approach. Also, we performed the theoretical safety analysis and conducted integral tests for the equipment integration through the Mock-up facility with non-radioactive samples. There were no major issues in the approach, however, material incompatibility of the alkaline metal and oxide in a salt at a high temperature and the reactor that contains the salt became a show stopper of the process. Also the difficulty of the clear separation of the salt with metals reduced from the oxide became a major issue

    The research reported here set out to investigate the features in schools and science departments that were seen as effective in contributing to the continuing professional development (CPD) of early career science teachers. Ten schools took part in the study, selected on the basis of their reputation for having effective CPD practices. To gain different perspectives from within the organisations we conducted interviews with senior members of staff, heads of science departments and early career teachers. A thematic analysis of the interviews is presented, drawing on findings from across the 10 schools, and exemplified in more detail by a vignette to show specific features of effective CPD practice. The study has revealed a wealth of practice across the 10 schools, which included a focus on broadening experience beyond the classroom, having an open, sharing, non-threatening culture and systemic procedures for mentoring and support that involved ring-fenced budgets. The schools also deployed staff judiciously in critical roles that model practice and motivate early career science teachers. Early career teachers were concerned primarily with their overall development as teachers, though some science specific examples such as observing practical work and sessions to address subject knowledge were seen as important.

    2015-01-01

    The project called High-Speed On-Board Data Processing for Science Instruments (HOPS) has been funded by NASA Earth Science Technology Office (ESTO) Advanced Information Systems Technology (AIST) program during April, 2012 â€" April, 2015. HOPS is an enabler for science missions with extremely high data processing rates. In this three-year effort of HOPS, Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) and 3-D Winds were of interest in particular. As for ASCENDS, HOPS replaces time domain data processing with frequency domain processing while making the real-time on-board data processing possible. As for 3-D Winds, HOPS offers real-time high-resolution wind profiling with 4,096-point fast Fourier transform (FFT). HOPS is adaptable with quick turn-around time. Since HOPS offers reusable user-friendly computational elements, its FPGA IP Core can be modified for a shorter development period if the algorithm changes. The FPGA and memory bandwidth of HOPS is 20 GB/sec while the typical maximum processor-to-SDRAM bandwidth of the commercial radiation tolerant high-end processors is about 130-150 MB/sec. The inter-board communication bandwidth of HOPS is 4 GB/sec while the effective processor-to-cPCI bandwidth of commercial radiation tolerant high-end boards is about 50-75 MB/sec. Also, HOPS offers VHDL cores for the easy and efficient implementation of ASCENDS and 3-D Winds, and other similar algorithms. A general overview of the 3-year development of HOPS is the goal of this presentation.

    The development, operation, and analysis of data from cubesats can promote science education and spur technology utilization in emerging and developing nations. This platform offers uniquely low construction and launch costs together with a comparative ubiquity of launch providers; factors that have led more than 80 universities and several emerging nations to develop programs in this field. Their small size and weight enables cubesats to “piggyback” on rocket launches and accompany orbiters travelling to Moon and Mars. It is envisaged that constellations of cubesats will be used for larger science missions. We present a brief history, technology overview, and summary of applications in science and industry for these small satellites. Cubesat technical success stories are offered along with a summary of pitfalls and challenges encountered in both developed and emerging nations. A discussion of economic and public policy issues aims to facilitate the decision-making process for those considering utilization of this unique technology.

  9. The need for strategic development of safety sciences.

    Busquet, Francois; Hartung, Thomas

    2017-01-01

    The practice of risk assessment and regulation of substances has largely developed as a patchwork of circumstantial additions to a nowadays more or less shared international toolbox. The dominant drivers from the US and Europe have pursued remarkably different approaches in the use of these tools for regulation, i.e., a more risk-based approach in the US and a more precautionary approach in Europe. We argue that there is need for scientific developments not only for the tools but also for their application, i.e., a need for Regulatory Science or, perhaps better, Safety Science. While some of this is emerging on the US side as strategic reports, e.g., from the National Academies, the NIH and the regulatory agencies, especially the EPA and the FDA, such strategic developments beyond technological developments are largely lacking in Europe or have started only recently at EFSA, ECHA or within the flagship project EU-ToxRisk. This article provides a rationale for the creation of a European Safety Sciences Institute (ESSI) based on regulatory and scientific needs, political context and current EU missions. Moreover, the possible modus operandi of ESSI will be described along with possible working formats as well as anticipated main tasks and duties. This mirrors the triple alliance on the American side (US EPA, NIH and FDA) in revamping regulatory sciences. Moreover, this could fit the political agenda of the European Commission for better implementation of existing EU legislation rather than creating new laws.

    Marchini, Leonardo Guedes

    2013-01-01

    Research and publications about luminescent polymers have been developed in the last years for the academic innovation; however the industrial application has been very limited in this area. Processed Optical markers are few explored due the difficult to process luminescent polymeric materials with stable luminescence. The materials used to process luminescent polypropylene (PP) were polyamide 6 (PA6) doped with europium complex [Eu(tta) 3 (H 2 O) 2 ] obtained through the dilution and casting process. The polyolefins because they are inert, do not fit the common procedure of doping, in consequence, in this work luminescent polypropylene was indirectly prepared by polyamide 6 doped with europium complex through extrusion process. Product characterization was done using Thermal gravimetry analysis (TG), Differential Scanning Calorimetric (DSC), X-Ray Diffraction (XRD), Infrared spectroscopy (FTIR) and spectro fluorescence of emission and excitation. The blend PP/PA6:Eu(tta) 3 presented luminescent properties, after semi-industrial process, as observed in the narrow bands of intra configuration transitions- 4f 6 relatives to energy levels 7 F 0 → 5 L 6 (394nm), 7 F 0 → 5 D 3 (415nm), 7 F 0 → 5 D 2 (464nm), 7 F 0 → 5 D 1 (525nm) e 7 F 0 → 5 D 0 (578nm) of emission spectrum. Red light of the pellets or film is emitted when excited in UV lamp (365nm). TG results showed under O 2 atmosphere that PP doped with PA6:Eu(tta) 3 was more stable than pure PP. In this work was processed luminescent PP/PA6:Eu(tta) 3 with properties of thermal and photo stability which can be used as optical marker in polymer processing. (author)

    In this session we describe an interdisciplinary course, The Art and Science of Photography (ASP), and its accompanying textbook and associated project-based activities, offered at the University of Wisconsin - Fox Valley in Menasha, Wisconsin. ASP uses photography as a point of departure to inspire students to ask fundamental questions about the nature of art, and to consider physics and astronomy as part of the study of nature. In turn, aspects of art and physics/astronomy are chosen in part for their direct relevance to the fundamentals of photography. For example, the subtle nature of shadows on a sunny day is related to the geometry of eclipses.ASP is offered as a 4-credit lecture/lab/studio course, and the students have a choice of registration for either art or natural-science credit. A large majority of students register for natural-science credit, and we suggest that ASP may be particularly useful as an entry point for students who view themselves as lacking ability in the sciences.Combining art with science in an introductory course is a particularly fruitful way to increase student engagement, as there is a perception that to be "artistic" precludes success in science. But it is of equal importance that students sometimes perceive that being "science-minded" precludes success in art.Part of the aim of ASP is to integrate art and science to such a degree that a student is always doing both, while still maintaining the integrity and rigor of each discipline. Towards this end, we have developed several unique hands-on practices that often use antiquarian photographic processes in a new way.Some of these hybrid techniques are little known or not previously described. Yet they allow for unique artistic expression, while also highlighting - in a way that ordinary digital photography does not - prinicpals of the interaction between light, atmosphere, weather, and the physical photographic substrate. These newly-described processes are accessible and inexpensive

    Zaleta, Kristy L.

    The purpose of this study was to investigate the impact of gender and type of inquiry curriculum (open or structured) on science process skills and epistemological beliefs in science of sixth grade students. The current study took place in an urban northeastern middle school. The researcher utilized a sample of convenience comprised of 303 sixth grade students taught by four science teachers on separate teams. The study employed mixed methods with a quasi-experimental design, pretest-posttest comparison group with 17 intact classrooms of students. Students' science process skills and epistemological beliefs in science (source, certainty, development, and justification) were measured before and after the intervention, which exposed different groups of students to different types of inquiry (structured or open). Differences between comparison and treatment groups and between male and female students were analyzed after the intervention, on science process skills, using a two-way analysis of covariance (ANCOVA), and, on epistemological beliefs in science, using a two-way multivariate analysis of covariance (MANCOVA). Responses from two focus groups of open inquiry students were cycle coded and examined for themes and patterns. Quantitative measurements indicated that girls scored significantly higher on science process skills than boys, regardless of type of inquiry instruction. Neither gender nor type of inquiry instruction predicted students' epistemological beliefs in science after accounting for students' pretest scores. The dimension Development accounted for 10.6% of the variance in students' science process skills. Qualitative results indicated that students with sophisticated epistemological beliefs expressed engagement with the open-inquiry curriculum. Students in both the sophisticated and naive beliefs groups identified challenges with the curriculum and improvement in learning as major themes. The types of challenges identified differed between the groups

    This paper reports that Lyondell Petrochemical Co., Houston, has developed a one step process to convert normal butylenes to isobutylene, a key component of methyl tertiary butyl ether (MTBE). MTBE is expected to become the additive of choice among U.S. refiners to blend oxygenated gasolines required by 1990 amendments to the Clean Air Act. Lyondell Pres. and Chief Executive Officer Bob Gower the the new process could help assure adequate supplies of MTBE to meet U.S. demand for cleaner burning fuels. Lyondell estimates the capital cost of building a grassroots plant to produce isobutylene with the new process would be less than half the cost of a grassroot plant to produce isobutylene with existing technology starting with normal butane

    Within the framework of "traditional" programmes, like the joint UNESCO-IUGS "International Geoscience Programme" (IGCP), the "International Continental Scientific Drilling Program" (ICDP), the "Integrated Ocean Drilling Program" (IODP) or the "International Lithosphere Programme" (ILP) numerous opportunities are provided to strengthen postgraduate geo-scientific education of representatives from developing countries. Recently established new initiatives, such as the "International Year of Planet Earth" (IYPE) or UNESCO's Global Network of Geoparks complement these in addition as important components to UNESCO's 'Education for All' programme, notably the youth, as well as to the United Nations Decade of Education for Sustainable Development (2005 - 2014). The "International Year of Planet Earth" is a joint initiative of the International Union of Geological Sciences (IUGS) and UNESCO. The central aims and ambitions of the Year, proclaimed for 2008 by the UN General Assembly, are to demonstrate the great potential of the Earth sciences in building a safer, healthier and wealthier society, and to encourage more widespread and effective application of this potential by targeting politicians and other decision-makers, educational systems, and the general public. Promotion of international collaboration, as well as capacity building and training of students of developing countries in all fields of Earth Sciences seem to be the most appropriate way to meet also the challenges of the IYPE. Another opportunity to improve the international recognition of Earth Scinces, also in developing countries, is the use of Geoparks as a promotional tool for education and popularization of Earth Sciences. Geoparks, notably those included in the European and/or Global Geoparks Networks, provide an international platform of cooperation and exchange between experts and practitioners in geological heritage matters, and are as such excellent instruments in highlighting Earth sciences.

    The US DOE Office of Technology Development (OTD) is currently evaluating the Plasma Hearth Process (PHP) for potential treatment of several DOE waste types. The PHP is a high-temperature vitrification process that has potential application for a wide range of mixed waste types in both the low-level and transuranic mixed waste categories. The PHP is being tested under both the OTD Mixed Waste Integrated Program and the Buried Waste Integrated Demonstration. Initial testing has been completed on several different surrogate waste forms that are representative of some of the DOE mixed waste streams. Destruction of organic material exceeds that of conventional incineration technologies. The vitrified residual has leaching characteristics comparable to glass formulations produced in the high-level waste program. The first phase of the PHP demonstration project has been successfully completed, and the project is currently beginning a comprehensive second phase of development and testing

    Full Text Available The Concise Data Processing Assessment (CDPA was developed to probe student abilities related to the nature of measurement and uncertainty and to handling data. The diagnostic is a ten question, multiple-choice test that can be used as both a pre-test and post-test. A key component of the development process was interviews with students, which were used to both uncover common modes of student thinking and validate item wording. To evaluate the reliability and discriminatory power of this diagnostic, we performed statistical tests focusing on both item analysis (item difficulty index, item discrimination index, and point-biserial coefficient and on the entire test (test reliability and Ferguson’s delta. Scores on the CDPA range from chance (for novices to about 80% (for experts, indicating that it possesses good dynamic range. Overall, the results indicate that the CDPA is a reliable assessment tool for measuring targeted abilities in undergraduate physics students.

    This study is to develop an advanced spent fuel management process for countries which have not yet decided a back-end nuclear fuel cycle policy. The aims of this process development based on the pyroreduction technology of PWR spent fuels with molten lithium, are to reduce the storage volume by a quarter and to reduce the storage cooling load in half by the preferential removal of highly radioactive decay-heat elements such as Cs-137 and Sr-90 only. From the experimental results which confirm the feasibility of metallization technology, it is concluded that there are no problems in aspects of reaction kinetics and equilibrium. However, the operating performance test of each equipment on an engineering scale still remain and will be conducted in 1999. (author). 21 refs., 45 tabs., 119 figs

    2007-01-01

    The University of Rochester's Graduate Experience in Science Education (GESE) course familiarizes biomedical science graduate students interested in pursuing academic career tracks with a fundamental understanding of some of the theory, principles, and concepts of science education. This one-semester elective course provides graduate students with practical teaching and communication skills to help them better relate science content to, and increase their confidence in, their own teaching abilities. The 2-h weekly sessions include an introduction to cognitive hierarchies, learning styles, and multiple intelligences; modeling and coaching some practical aspects of science education pedagogy; lesson-planning skills; an introduction to instructional methods such as case studies and problem-based learning; and use of computer-based instructional technologies. It is hoped that the early development of knowledge and skills about teaching and learning will encourage graduate students to continue their growth as educators throughout their careers. This article summarizes the GESE course and presents evidence on the effectiveness of this course in providing graduate students with information about teaching and learning that they will use throughout their careers.

    As a part of research efforts to develop an advanced spent fuel management process, this project focused on the electrochemical reduction technology which can replace the original Li reduction technology of ANL, and we have successfully built a 20 kgHM/batch scale demonstration system. The performance tests of the system in the ACPF hot cell showed more than a 99% reduction yield of SIMFUEL, a current density of 100 mA/cm{sup 2} and a current efficiency of 80%. For an optimization of the process, the prevention of a voltage drop in an integrated cathode, a minimization of the anodic effect and an improvement of the hot cell operability by a modulation and simplization of the unit apparatuses were achieved. Basic research using a bench-scale system was also carried out by focusing on a measurement of the electrochemical reduction rate of the surrogates, an elucidation of the reaction mechanism, collecting data on the partition coefficients of the major nuclides, quantitative measurement of mass transfer rates and diffusion coefficients of oxygen and metal ions in molten salts. When compared to the PYROX process of INL, the electrochemical reduction system developed in this project has comparative advantages in its application of a flexible reaction mechanism, relatively short reaction times and increased process yields.

    The development status and existing problems in the field of nuclear agricultural sciences (NAS) are reviewed. Including the application of nuclear technology in mutation breeding by irradiation, isotopic technique application, food irradiation and sterile insect technique, etc. China has made great achievements in the research and application of nuclear technique in agriculture from 1950s to 1990s. Due to lack of enough financial support to the basic research and reformation of science and research system in China, the development of NAS now meets its tough time. Through analyzing the difference and reasons of NAS development between China and the USA, it is recognized that the innovation in research and scientific system is important for promoting the development speed and research level of NAS.

    A novel data science workflow is developed and demonstrated to extract process-structure linkages (i.e., reduced-order model) for microstructure evolution problems when the final microstructure depends on (simulation or experimental) processing parameters. Our workflow consists of four main steps: data pre-processing, microstructure quantification, dimensionality reduction, and extraction/validation of process-structure linkages. These methods that can be employed within each step vary based on the type and amount of available data. In this paper, this data-driven workflow is applied to a set of synthetic additive manufacturing microstructures obtained using the Potts-kinetic Monte Carlo (kMC) approach. Additive manufacturing techniques inherently produce complex microstructures that can vary significantly with processing conditions. Using the developed workflow, a low-dimensional data-driven model was established to correlate process parameters with the predicted final microstructure. In addition, the modular workflows developed and presented in this work facilitate easy dissemination and curation by the broader community.

    Lecture will be in English– Translation available in French Without any doubt, CERN can be described as being among the most ambitious scientific enterprises ever undertaken. For 60 years, the Member States have not only invested considerable financial means into this institution, but have also supported the creation of a highly visionary research programme. And this has led to a change in the way science is done, as captured by the idea of "big science". Yet this naturally also raises a number of quite fundamental questions: How did the meaning of "doing science" change? What justifies societal engagement with and support for such a cost-intensive long-term scientific undertaking? And finally, in what ways does (and did) this research enterprise contribute to the development of contemporary societies? By focusing on some key examples, the talk will thus explore how the ways of doing research and scientific and societal relations have undergone change over the ...

    Mahfood, Denise Marcia

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

    Despite recent and growing interest in using Twitter to examine human behavior and attitudes, there is still significant room for growth regarding the ability to leverage Twitter data for social science research. In particular, gleaning demographic information about Twitter users-a key component of much social science research-remains a challenge. This article develops an accurate and reliable data processing approach for social science researchers interested in using Twitter data to examine behaviors and attitudes, as well as the demographic characteristics of the populations expressing or engaging in them. Using information gathered from Twitter users who state an intention to not vote in the 2012 presidential election, we describe and evaluate a method for processing data to retrieve demographic information reported by users that is not encoded as text (e.g., details of images) and evaluate the reliability of these techniques. We end by assessing the challenges of this data collection strategy and discussing how large-scale social media data may benefit demographic researchers.

This study sought to explore how this model affects elementary in-service teachers' feelings of self-efficacy toward science and science teaching. Interactive Qualitative Research (IQR), a systems approach of natural inquiry, was used for this study. Theory is grounded in the data collected and analyzed through group processes. A core group of teachers, key teachers representing grades one through six and lead teachers the campus contact representatives, received professional development education from university professors in semi-monthly after school workshops and in a three week summer science institute held on-site. In this study, (N = 18) key and lead teachers participated in a focus group, a picture board exercise (a projective type exercise), interviews, and classroom observations. Within the system of the MSEC professional development model, cause and effect relationships among eleven phenomena were identified which had the greatest impact on the teachers' feelings of self-efficacy and science teaching practices. Changed teaching practices were indicated by inquiry-based science lessons with students as active learners. Five principles of self-efficacy: (1) efficacy; (2) goals setting; (3) values; (4) expectancy; and, (5) control beliefs were used to evaluate efficacy beliefs. Findings from the data collection and analysis identified two phenomena, the university instructional leadership role and teacher time commitments and time constraints, both internally and externally imposed, which seemed to have the greatest impact on elementary teachers

    Through the application of specialized systems, future-orientated information processing integrates the sciences of processes, control systems, process control strategies, user behaviour and ergonomics. Improvements in process control can be attained, inter alia, by the preparation of the information contained (e.g. by suppressing the flow of signals and replacing it with signals which are found on substance) and also by an ergonomic representation of the study of the process.

    Science Process Skills (SPS) has not been optimally trained to the students in the learning activity. The aim of this research is finding the ways to train SPS on the subject of Work and Energy. One shot case study design is utilized in this research that conducted on 32 students in one of the High Schools in Bandung. The students’ SPS responses were analyzed by the development SPS based assessment portfolios. The results of this research showed the didactic design that had been designed to training the identifying variables skills, formulating hypotheses, and the experiment activity shows the development. But the didactic design to improve the students’ predicting skills shows that the development is still not optimal. Therefore, in the future studies need to be developed the didactic design on the subject Work and Energy that exercising these skills.

    Malaysia's economy continues to be dependent upon the primary producing sectors, based on the exploitation or use of her natural resources. At this Malaysia is the world's largest exporter of natural rubber, tin, tropical hardwoods and palm oil. There is still wide scope for developing new application of science and technology in the rubber industry, and the scope remains even wider in other agricultural sectors. In order to accelerate development in the traditional agricultural sector, that is, those related to food production, the Malaysian Agricultural Research and Development Institute (MARDI) was established in 1970 to undertake research in the development of crops other than rubber. Progress has been relatively slow in the development of agriculture. In forestry much work needs to be done in the application of science and technology to forest management, logging, timber utilization, silviculture and the related field of forest regeneration, tree breeding, forest protection and soil conservation. Further development of the mining sector calls for the application of new technology both in prospecting for new sources of minerals and in exploitation. Development of off-shore technology will become increasingly important. Although a major sector in resources development is energy, there is, as yet, no energy policy. Structural diversification is recognized as a basic need for the economic development of Malaysia. Malaysia will have a great demand for trained scientific and technological personnel.

    While training in statistical methods is an important part of many earth scientists' training, these scientists often learn the bulk of their software development skills in an ad hoc, just-in-time manner. Yet to carry out contemporary research scientists are spending more and more time developing software. Here I present perspectives - as an earth sciences graduate student with professional software engineering experience - on the challenges scientists face adopting software engineering practices, with an emphasis on areas of the science software development lifecycle that could benefit most from improved engineering. This work builds on experience gained as part of the NSF-funded Water Science Software Institute (WSSI) conceptualization award (NSF Award # 1216817). Throughout 2013, the WSSI team held a series of software scoping and development sprints with the goals of: (1) adding features to better model green infrastructure within the Regional Hydro-Ecological Simulation System (RHESSys); and (2) infusing test-driven agile software development practices into the processes employed by the RHESSys team. The goal of efforts such as the WSSI is to ensure that investments by current and future scientists in software engineering training will enable transformative science by improving both scientific reproducibility and researcher productivity. Experience with the WSSI indicates: (1) the potential for achieving this goal; and (2) while scientists are willing to adopt some software engineering practices, transformative science will require continued collaboration between domain scientists and cyberinfrastructure experts for the foreseeable future.

    The quality of science teaching is of growing importance in Mexico. Mexican students score well below the world mean in math and science. Although the government has recognized these deficiencies and has implemented new policies aimed to improve student achievement in the sciences, teachers are still encountering in-class barriers to effective teaching, especially in public colleges. This paper reports on the utility of inquiry based exercises in Mexican classrooms. In particular, it describes a two-day professional development workshop with science teachers at the Instituto Tecnologico Superior in Felipe Carrillo Puerto in the Mexican state of Quintana Roo. Felipe Carrillo Puerto is an indigenous municipality where a significant majority of the population speak Maya as their first language. This alone presents a unique barrier to teaching science in the municipality, but accompanied with other factors such as student apathy, insufficient prior training of both students and teachers, and pressure to deliver specific science curriculum, science teachers have formidable challenges for effective science teaching. The goals of the workshop were to (1) have a directed discussion regarding science as both content and process, (2) introduce inquiry based learning as one tool of teaching science, and (3) get teachers to think about how they can apply these techniques in their classes.

    As the strategy for DUPIC(Direct Use of spent PWR fuel In CANDU reactor) process safeguards, the neutron detection method was introduced to account for nuclear materials in the whole DUPIC process by selectively measuring spontaneous fission neutron signals from {sup 244}Cm. DSNC was designed and manufactured to measure the account of curium in the fuel bundle and associated process samples in the DUPIC fuel cycle. The MCNP code had response profile along the length of the CANDU type fuel bundle. It was found experimentally that the output signal variation due to the overall azimuthal asymmetry was less than 0.2%. The longitudinal detection efficiency distribution at every position including both ends was kept less than 2% from the average value. Spent fuel standards almost similar to DUPIC process material were fabricated from a single spent PWR fuel rod and the performance verification of the DSNC is in progress under very high radiation environment. The results of this test will be eventually benchmarked with other sources such as code simulation, chemical analysis and gamma analysis. COREMAS-DUPIC has been developed for the accountability management of nuclear materials treated by DUPIC facility. This system is able to track the controlled nuclear materials maintaining the material inventory in near-real time and to generate the required material accountability records and reports. Concerning the containment and surveillance technology, a focused R and D effort is given to the development of unattended continuous monitoring system. Currently, the component technologies of radiation monitoring and surveillance have been established, and continued R and D efforts are given to the integration of the components into automatic safeguards diagnostics.

    (The primary source of electric propulsion development throughout NASA is managed by the In-Space Propulsion Technology Project at the NASA Glenn Research Center for the Science Mission Directorate. The objective of the Electric Propulsion project area is to develop near-term electric propulsion technology to enhance or enable science missions while minimizing risk and cost to the end user. Major hardware tasks include developing NASA s Evolutionary Xenon Thruster (NEXT), developing a long-life High Voltage Hall Accelerator (HIVHAC), developing an advanced feed system, and developing cross-platform components. The objective of the NEXT task is to advance next generation ion propulsion technology readiness. The baseline NEXT system consists of a high-performance, 7-kW ion thruster; a high-efficiency, 7-kW power processor unit (PPU); a highly flexible advanced xenon propellant management system (PMS); a lightweight engine gimbal; and key elements of a digital control interface unit (DCIU) including software algorithms. This design approach was selected to provide future NASA science missions with the greatest value in mission performance benefit at a low total development cost. The objective of the HIVHAC task is to advance the Hall thruster technology readiness for science mission applications. The task seeks to increase specific impulse, throttle-ability and lifetime to make Hall propulsion systems applicable to deep space science missions. The primary application focus for the resulting Hall propulsion system would be cost-capped missions, such as competitively selected, Discovery-class missions. The objective of the advanced xenon feed system task is to demonstrate novel manufacturing techniques that will significantly reduce mass, volume, and footprint size of xenon feed systems over conventional feed systems. This task has focused on the development of a flow control module, which consists of a three-channel flow system based on a piezo-electrically actuated

    Whereas the very birth of the U.S. Geological Survey arose from the recommendations of a National Academy of Sciences report, water science has not always had a prominent place at that institution. Prior to the 1980s, water issues were dealt with on an ad hoc basis by various boards related to science, engineering, and policy. With the birth of the Water Science and Technology Board (WSTB) in 1982, a diversity of water-related issues are now handled under one roof. The "business" of the WSTB is to produce consensus reports on a spectrum of topics in water science. Some of the projects that the WSTB works on are self-generated. The majority are generated either by Congress, or by government agencies. The WSTB takes on several different kinds of studies. Some of these are designed to advance the science of hydrology itself. This category would include the report Opportunities in the Hydrologic Sciences, which helped to establish hydrologic science as something separate from applied hydrology in Congress, the White House, and agencies such as NSF. However, the majority of the board's consensus studies involve hydrology in the interests of improving the natural and human environment. For example, Water for the Future: The West Bank and Gaza Strip, Israel, and Jordan outlined consensus principles backed by scientists from all of these entities for sustaining freshwater resources of the region. Closer to home, but no less controversial, a WSTB committee recently reached consensus on improving the process by which states determine which water bodies are polluted enough to require clean-up, and develop Total Maximum Daily Loads for these pollutants. Another committee recently sorted through the scientific bases for using natural attenuation for various contaminants in ground water and soil. And an ongoing committee is trying to help the South Florida scientific community to determine the best strategies for restoring the Everglades to some semblance of its former self

    The increasing population and industrialization, worldover, is placing escalating demands for the development of newer technologies that are environment friendly and minimize the pollution associated with the development. Radiation technology can be of benefit in reducing the pollution levels associated with many processes. The sulphur vulcanization method for natural rubber latex vulcanization results in the formation of considerable amounts of nitrosoamines, both in the product as well as in the factory environment. Radiation vulcanization of natural rubber latex has emerged as a commercially viable alternative to produce sulphur and nitrosoamine free rubber. A Co-60 γ-radiation based pilot plant has been functioning since April 1993 to produce vulcanized natural rubber latex (RVNRL) using acrylate monomers as sensitizer. The role of sensitizer, viz. n-butyl acrylate in the vulcanization process has been elucidated using the pulse radiolysis technique. Emission of toxic sulphur containing gases form an inevitable part of viscose-rayon process and this industry is in search of ways to reduce the associated pollution levels. The irradiation of cellulose results in cellulose activation and reduction in the degree of polymerization (DP). These effects can reduce the solvents required to dissolve the paper pulp. There is a keen interest in utilizing radiation technology in viscose rayon production. We have utilized the electron beam (EB) accelerator for reducing the degree of polymerization (DP) of paper pulp. Laboratory scale tests have been carried out to standardize the conditions for production of pulp having the desired DP by EB irradiation. The use of irradiated paper pulp can result in ∼40% reduction in the consumption of CS 2 in the process that can be beneficial in reducing the pollution associated with the process. PTFE waste can be recycled into a low molecular weight microfine powder by irradiation. An EB based process has been standardized to produce

    Toro Energy Ltd. has identified a resource of 20.2 million tonnes at a grade of 548 ppm U{sub 3}O{sub 8} at Wiluna, Western Australia. Calcrete and clay delta formations host the uranium mineral carnotite. Initial studies indicate a mining operation is technically, environmentally and commercially viable. Increase in demand for uranium and a change in State Government policy on uranium mining have lead Toro to proceed with a bankable feasibility study and commence approvals with State and Federal Governments. This paper discusses how Toro arrived at the decision to utilise alkaline heap leach, a process not widely used, and how it is being developed. (author)

    The Europlanet H2020 programme will develop a research infrastructure in Horizon 2020. The programme includes a follow-on to the FP7 activity aimed at developing the Planetary Science Virtual Observatory (VO). This activity is called VESPA, which stands for Virtual European Solar and Planetary Access. Building on the IDIS activity of Europlanet FP7, VESPA will distribute more data, will improve the connected tools and infrastructure, and will help developing a community of both users and data providers. One goal of the Europlanet FP7 programme was to set the basis for a European Virtual Observatory in Planetary Science. A prototype has been set up during FP7, most of the activity being dedicated to the definition of standards to handle data in this field. The aim was to facilitate searches in big archives as well as sparse databases, to make on-line data access and visualization possible, and to allow small data providers to make their data available in an interoperable environment with minimum effort. This system makes intensive use of studies and developments led in Astronomy (IVOA), Solar Science (HELIO), plasma physics (SPASE), and space archive services (IPDA). It remains consistent with extensions of IVOA standards.

    The partitioning process has developed and demonstrated that the solvent extraction with diisodecylphosphoric acid (DIDPA) can successfully separate transuranium elements from a high-level liquid waste. In the solvent extraction, DIDPA is decomposed by radiolysis and hydrolysis. The main degradation product is monoisodecyl phosphoric acid (MIDPA). Ethylene glycol has been used for removing the product by a solvent extraction method. However this method has two drawbacks that two phases separate slowly and the used ethylene glycol is not regeneratable. First it was found that the addition of acetone or methanol with 20 volume % improved the phase separation. Then a new purification method was developed by using an aqueous solution of methanol or acetone. The new purification method is as excellent as the ethylene glycol method for the removal of MIDPA.

    A number of decisions in the health care field rely heavily on published clinical evidence. A systematic approach to evidence development and publication planning is required to develop a portfolio of evidence that includes at minimum information on efficacy, safety, durability of effect, quality of life, and economic outcomes. The approach requires a critical assessment of available literature, identification of gaps in the literature, and a strategic plan to fill the gaps to ensure the availability of evidence demanded for clinical decisions, coverage/payment decisions and health technology assessments. The purpose of this manuscript is to offer a six-step strategic process leading to a portfolio of evidence that meets the informational needs of providers, payers, and governmental agencies concerning patient access to a therapy.

The application of the radiation protection knowledge and technology developed in this program provides cradle-to-grave management for CANDU and related nuclear technologies. This document provides an overview of the Environmental Science and Technology (ES and T) program which is one of the technical areas of R and D within the radiological R and D program. The ES and T program uses science from three main areas: radiochemistry, mathematical modelling and environmental assessment. In addition to providing an overview of the program, this summary also gives specific examples of recent technical work in each of the three areas. These technical examples illustrate the applied nature of the ES and T program and the close coupling of the program to CANDU customer requirements. (author)

    Earth Science II: The Solid Earth -- Earth History and Planetary Science -- is the second of two Earth Science courses, and one of eleven graduate level science Contextualized Content Courses (CCC), that have been developed by the Boston Science Partnership as part of an NSF-funded Math Science Partnership program. A core goal of these courses is to provide high level science content to middle and high school teachers while modeling good instructional practices directly tied to the Boston Public Schools and Massachusetts science curriculum frameworks. All of these courses emphasize hands-on, lab-based, inquiry-driven, student-centered lessons. The Earth Science II team aimed to strictly adhere to ABC (Activity Before Concept) and 5E/7E models of instruction, and limited lecture or teacher-centered instruction to the later “Explanation” stages of all lessons. We also introduced McNeill and Krajick’s Claim-Evidence-Reasoning (CER) model of scientific explanation for middle school classroom discourse, both as a powerful scaffold leading to higher levels of accountable talk in the classroom, and to model science as a social construct. Daily evaluations, dutifully filled out by the course participants and diligently read by the course instructors, were quite useful in adapting instruction to the needs of the class on a real-time basis. We find the structure of the CCC teaching teams - university-based faculty providing expert content knowledge, K-12-based faculty providing age appropriate pedagogies and specific links to the K-12 curriculum - quite a fruitful, two-way collaboration. From the students’ perspective, one of the most useful takeaways from the university-based faculty was “listening to experts model out loud how they reason,” whereas some of the more practical takeaways (i.e., lesson components directly portable to the classroom?) came from the K-12-based faculty. The main takeaways from the course as a whole were the promise to bring more hands

    Science is increasingly being conducted in large, interdisciplinary teams. As team size increases, challenges can arise during manuscript development, where achieving one team goal (e.g., inclusivity) may be in direct conflict with other goals (e.g., efficiency). Here, we present strategies for effective collaborative manuscript development that draw from our experiences in an interdisciplinary science team writing collaborative manuscripts for six years. These strategies are rooted in six guiding principles that were important to our team: to create a transparent, inclusive, and accountable research team that promotes and protects team members who have less power to influence decision‐making while fostering creativity and productivity. To help alleviate the conflicts that can arise in collaborative manuscript development, we present the following strategies: understand your team composition, create an authorship policy and discuss authorship early and often, openly announce manuscript ideas, identify and communicate the type of manuscript and lead author management style, and document and describe authorship contributions. These strategies can help reduce the probability of group conflict, uphold individual and team values, achieve fair authorship practices, and increase science productivity.

    2013-01-01

    Academic institutions and researchers are becoming increasingly involved in translational research to spur innovation in addressing many complex biomedical and societal problems, and in response to the focus of the NIH and other funders. One approach to translational research is to development interdisciplinary research teams. By bringing together collaborators with diverse research backgrounds and perspectives, these teams seek to blend their science and the workings of the scientists to push beyond the limits of current research. While team-science promises individual and team benefits in creating and implementing innovations, its increased complexity poses challenges. In particular, since academic career advancement commonly focuses on individual achievement, team-science might differentially impact early stage researchers. This need to be recognized for individual accomplishments in order to move forward in an academic career may give rise to research-team conflicts. Raising awareness to career-related aspects of team science will help individuals (particularly trainees and junior faculty) take steps to align their excitement and participation with the success of both the team and their personal career advancement.

    Many college students experience difficulties in basic academic skills. Recent research suggests that much of this difficulty may lie in heuristic competency--the ability to use and successfully manage general cognitive strategies. In the present study, the authors evaluated this possibility. They compared participants' performance on a practice California Basic Educational Skills Test and on a series of questions in the natural sciences with heuristic and algorithmic performance on a series of mathematics and reading comprehension exercises. Heuristic competency in mathematics was associated with better scores in science and mathematics. Verbal and algorithmic skills were associated with better reading comprehension. These results indicate the importance of including heuristic training in educational contexts and highlight the importance of a relatively domain-specific approach to questions of cognition in higher education.

    Software development for the Chandra X-ray Center Data System began in the mid 1990's, and the waterfall model of development was mandated by our documents. Although we initially tried this approach, we found that a process with elements of the spiral model worked better in our science-based environment. High-level science requirements are usually established by scientists, and provided to the software development group. We follow with review and refinement of those requirements prior to the design phase. Design reviews are conducted for substantial projects within the development team, and include scientists whenever appropriate. Development follows agreed upon schedules that include several internal releases of the task before completion. Feedback from science testing early in the process helps to identify and resolve misunderstandings present in the detailed requirements, and allows review of intangible requirements. The development process includes specific testing of requirements, developer and user documentation, and support after deployment to operations or to users. We discuss the process we follow at the Chandra X-ray Center (CXC) to develop software and support operations. We review the role of the science and development staff from conception to release of software, and some lessons learned from managing CXC software development for over a decade.

    2000-01-01

    The simple goal of the Human Research Facility (HRF) is to conduct human research experiments on the International Space Station (ISS) astronauts during long-duration missions. This is accomplished by providing integration and operation of the necessary hardware and software capabilities. A typical hardware development flow consists of five stages: functional inputs and requirements definition, market research, design life cycle through hardware delivery, crew training, and mission support. The purpose of this presentation is to guide the audience through the early hardware development process: requirement definition through selecting a development path. Specific HRF equipment is used to illustrate the hardware development paths. The source of hardware requirements is the science community and HRF program. The HRF Science Working Group, consisting of SCientists from various medical disciplines, defined a basic set of equipment with functional requirements. This established the performance requirements of the hardware. HRF program requirements focus on making the hardware safe and operational in a space environment. This includes structural, thermal, human factors, and material requirements. Science and HRF program requirements are defined in a hardware requirements document which includes verification methods. Once the hardware is fabricated, requirements are verified by inspection, test, analysis, or demonstration. All data is compiled and reviewed to certify the hardware for flight. Obviously, the basis for all hardware development activities is requirement definition. Full and complete requirement definition is ideal prior to initiating the hardware development. However, this is generally not the case, but the hardware team typically has functional inputs as a guide. The first step is for engineers to conduct market research based on the functional inputs provided by scientists. CommerCially available products are evaluated against the science requirements as

    Full Text Available Lean product development (LPD is an approach that comprises lean principles and management practices that aim to reduce waste and improve operational effectiveness throughout the entire value stream in continuous improvement endless journey. Due to that, the ability to innovate, change and learn continuously is a key element in order to minimize product development problems. Several LPD techniques are presented in the literature as possible enablers for lean implementation. However, little has been known about the impact of these enablers on the problems related to product development processes. Thus, this paper aims to examine the relationship between five LPD practices’ constructs and the occurrence frequency of eleven LPD problems’ constructs in companies that are implementing lean. Moreover, the identification of relevant relationships between LPD practices’ and problems’ constructs may contribute to specify the contexts in which problems are expected to occur. The study sample comprises sixty four companies already undergoing lean implementation both in shop floor and offices area. The results indicate that the same practices’ constructs, which are deemed as influential for minimizing LPD problems, present different relationship intensities among them.

    Members of the laser program at Lawrence Livermore National Laboratory (LLNL) reviewed potential applications of lasers in industry, some of which are: isotope separation; cleanup of radioactive waste; trace impurity removal; selective chemical reactions; photochemical activation or dissociation of gases; control of combustion particulates; crystal and powder chemistry; and laser induced biochemistry. Many of these areas are currently under active study in the community. The investigation at LLNL focused on laser isotope separation of atomic uranium because of the large demand (> 1000 tonnes/year) and high product enrichment price (> $600/kg of product) for material used as fuel in commercial light-water nuclear power reactors. They also believed that once the technology was fully developed and deployed, it could be applied directly to separating many elements economically on an industrial scale. The Atomic Vapor Laser Isotope Separation (AVLIS) program at LLNL has an extensive uranium and plutonium program of >$100 M in FY85 and a minor research program for other elements. This report describes the AVLIS program conducted covering the following topics; candidate elements; separative work units; spectroscopic selectivety; major systems; facilities; integrated process model;multivariable sensitivety studies; world market; and US enrichment enterprise. 23 figs.

    The research on spent fuel management focuses on the maximization of the disposal efficiency by a volume reduction, the improvement of the environmental friendliness by the partitioning and transmutation of the long lived nuclides, and the recycling of the spent fuel for an efficient utilization of the uranium source. In the second phase which started in 2001, the performance test of the advanced spent fuel management process consisting of voloxidation, reduction of spent fuel and the lithium recovery process has been completed successfully on a laboratory scale. The world-premier spent fuel reduction hot test of a 5 kgHM/batch has been performed successfully by joint research with Russia and the valuable data on the actinides and FPs material balance and the characteristics of the metal product were obtained with experience to help design an engineering scale reduction system. The electrolytic reduction technology which integrates uranium oxide reduction in a molten LiCl-Li 2 O system and Li 2 O electrolysis is developed and a unique reaction system is also devised. Design data such as the treatment capacity, current density and mass transfer behavior obtained from the performance test of a 5 kgU/batch electrolytic reduction system pave the way for the third phase of the hot cell demonstration of the advanced spent fuel management technology

  12. Hanford Integrated Planning Process: 1993 Hanford Site-specific science and technology plan

    International Nuclear Information System (INIS)

    1993-12-01

    This document is the FY 1993 report on Hanford Site-specific science and technology (S ampersand T) needs for cleanup of the Site as developed via the Hanford Integrated Planning Process (HIPP). It identifies cleanup problems that lack demonstrated technology solutions and technologies that require additional development. Recommendations are provided regarding allocation of funding to address Hanford's highest-priority technology improvement needs, technology development needs, and scientific research needs, all compiled from a Sitewide perspective. In the past, the S ampersand T agenda for Hanford Site cleanup was sometimes driven by scientists and technologists, with minimal input from the ''problem owners'' (i.e., Westinghouse Hanford Company [WHC] staff who are responsible for cleanup activities). At other times, the problem-owners made decisions to proceed with cleanup without adequate scientific and technological inputs. Under both of these scenarios, there was no significant stakeholder involvement in the decision-making process. One of the key objectives of HIPP is to develop an understanding of the integrated S ampersand T requirements to support the cleanup mission, (a) as defined by the needs of the problem owners, the values of the stakeholders, and the technology development expertise that exists at Hanford and elsewhere. This requires a periodic, systematic assessment of these needs and values to appropriately define a comprehensive technology development program and a complementary scientific research program. Basic to our success is a methodology that is defensible from a technical perspective and acceptable to the stakeholders

    Technology assessments of fourteen science instruments were conducted within NASA using the NASA Technology Readiness Level (TRL) Metric. The instruments were part of three NASA Earth Science Decadal Survey missions in pre-formulation. The Earth Systematic Missions Program (ESMP) Systems Engineering Working Group (SEWG), composed of members of three NASA Centers, provided a newly modified electronic workbook to be completed, with instructions. Each instrument development team performed an internal assessment of its technology status, prepared an overview of its instrument, and completed the workbook with the results of its assessment. A team from the ESMP SEWG met with each instrument team and provided feedback. The instrument teams then reported through the Program Scientist for their respective missions to NASA's Earth Science Division (ESD) on technology readiness, taking the SEWG input into account. The instruments were found to have a range of TRL from 4 to 7. Lessons Learned are presented; however, due to the competition-sensitive nature of the assessments, the results for specific missions are not presented. The assessments were generally successful, and produced useful results for the agency. The SEWG team identified a number of potential improvements to the process. Particular focus was on ensuring traceability to guiding NASA documents, including the NASA Systems Engineering Handbook. The TRL Workbook has been substantially modified, and the revised workbook is described.

  14. Lucky Belief in Science Education - Gettier Cases and the Value of Reliable Belief-Forming Processes

    Science.gov (United States)

    Brock, Richard

    2018-05-01

    The conceptualisation of knowledge as justified true belief has been shown to be, at the very least, an incomplete account. One challenge to the justified true belief model arises from the proposition of situations in which a person possesses a belief that is both justified and true which some philosophers intuit should not be classified as knowledge. Though situations of this type have been imagined by a number of writers, they have come to be labelled Gettier cases. Gettier cases arise when a fallible justification happens to lead to a true belief in one context, a case of `lucky belief'. In this article, it is argued that students studying science may make claims that resemble Gettier cases. In some contexts, a student may make a claim that is both justified and true but which arises from an alternative conception of a scientific concept. A number of instances of lucky belief in topics in science education are considered leading to an examination of the criteria teachers use to assess students' claims in different contexts. The possibility of lucky belief leads to the proposal that, in addition to the acquisition of justified true beliefs, the development of reliable belief-forming processes is a significant goal of science education. The pedagogic value of various kinds of claims is considered and, it is argued, the criteria used to judge claims may be adjusted to suit the context of assessment. It is suggested that teachers should be alert to instances of lucky belief that mask alternative conceptions.

    Many physiological, environmental, and operational risks exist for crewmembers during spaceflight. An understanding of these risks from an integrated perspective is required to provide effective and efficient mitigations during future exploration missions that typically have stringent limitations on resources available, such as mass, power, and crew time. The Human Research Program (HRP) is in the early stages of developing collaborative modeling approaches for the purposes of managing its science portfolio in an integrated manner to support cross-disciplinary risk mitigation strategies and to enable resilient human and engineered systems in the spaceflight environment. In this talk, we will share ideas being explored from fields such as network science, complexity theory, and system-of-systems modeling. Initial work on tools to support these explorations will be discussed briefly, along with ideas for future efforts.

    2016-12-01

    Just as the Next Generation Science Standards (NGSSs) call for change in what students learn and how they are taught, teacher education programs must reconsider courses and curriculum in order to prepare teacher candidates to understand and implement new standards. In this study, we examine the development of prospective elementary teachers' practical knowledge of the NGSS in the context of a science methods course and innovative field experience. We present three themes related to how prospective teachers viewed and utilized the standards: (a) as a useful guide for planning and designing instruction, (b) as a benchmark for student and self-evaluation, and (c) as an achievable vision for teaching and learning. Our findings emphasize the importance of collaborative opportunities for repeated teaching of the same lessons, but question what is achievable in the context of a semester-long experience.

    Larrinaga McGee, Patria Maria

    Current education reform calls for excellence, access, and equity in all areas of instruction, including science and literacy. Historically, persons of diverse backgrounds or with disabilities have been underrepresented in science. Gaps are evident between the science and literacy achievement of diverse students and their mainstream peers. The purpose of this study was to document, describe, and examine patterns of development and change in the science learning and literacy performance of Hispanic students. The two major questions of this study were: (1) How is science content knowledge, as evident in oral and written formats, manifested in the performance of typically developing, at-risk, and disabled non-English language background (NELB) students? and (2) What are the patterns of literacy performance in science, and as evident in oral and written formats, among typically developing, at-risk, and disabled NELB students? This case study was part of a larger research project, the Promise Project, undertaken at the University of Miami, Coral Gables, Florida, under the sponsorship of the National Science Foundation. The study involved 24 fourth-grade students in seven classrooms located in Promise Project schools where teachers were provided with training and materials for instruction on two units of science content: Matter and Weather. Four students were selected from among the fourth-graders for a closer analysis of their performance. Qualitative and quantitative data analysis methods were used to document, describe, and examine specific events or phenomena in the processes of science learning and literacy development. Important findings were related to (a) gains in science learning and literacy development, (b) students' science learning and literacy development needs, and (c) general and idiosyncratic attitudes toward science and literacy. Five patterns of science "explanations" identified indicated a developmental cognitive/linguistic trajectory in science

    2011-10-01

    Some scepticism has been voiced over whether the work of John Hughlings Jackson possesses any significant philosophical orientation. This article argues that Hughlings Jackson was acquainted with the work of a wide range of philosophers. In particular, certain aspects of the writings of John Stuart Mill are reflected in Hughlings Jackson's own work. From early in his career, Hughlings Jackson adopted a critical stance in his neurological papers, seeking to expose shortcomings in the conventional practices of his peers and urging greater methodological rigour and sophistication in order to advance their science. This critical and 'procedurist' bias endows Hughlings Jackson's writings with a characteristically modern character.

    Those involved in providing faculty development may be among only a few individuals for whom faculty development is an interest and priority within their work setting. Furthermore, funding to support faculty development is limited. In 2010, an interprofessional, self-formed, faculty learning community on faculty development in teaching was established to promote collaboration on faculty development initiatives that have transference to faculty members across disciplines and to share expertise and resources for wider impact. The organic structure and processes of the faculty learning community created an environment that has not only resulted in an increased offering of faculty development opportunities and resources across the health science campus, but has created a rich environment that combines the knowledge, innovation, and experience to promote collaborative efforts that benefit all. The background, structure, processes, successes, and lessons learned of the interprofessional faculty learning community on faculty development in teaching are described.

    Research on radiation processing of natural polymer such as polysaccharides of chitosan, cellulose, carrageenan has been carried out in Sri Lanka since the year 2004. The research group have been involving in development activities on application of chitin and chitosan for wound dressing, irradiated chitosan on shelf life extension of fruits such as papaya, banana, mangoes, radiation crosslinked super-absorbent hydrogel from sodium carboxymethyl cellulose by radiation processing. Hydrogels prepared with PVA/Carrageenan/Agar has been studied on guinea pigs to determine the wound healing effect. Irradiated chitosan powder and chitosan solution was studied in vitro and found chitosan solution (1%) directly subjected to irradiation dosages even at 5 kGy was highly effective in control of anthracnose causing organism of papaya. In vivo studies with irradiated 1% chitosan solution on Rathana and red lady variety of papaya shows better control of spoilage of papaya to a considerable extent. The government of Sri Lanka (Ministry of Science and Technology and Atomic Energy Authority) is in the process of establishing the first government owned Multipurpose Gamma Irradiation Facility and it will be helpful to transfer the output of R and D in radiation processing.

    At NASA's Langley Research Center, the Science Directorate participates in a wide range of public outreach events, from individual small-scale classroom visits, to the large-scale NASA events like Exploration Day at Busch Gardens Williamsburg. Despite the diversity of venues, one thing is certain: the public is hungry for science and ravenous for the materials and activities that NASA produces. However, designing and producing materials and activities to capture the attention of everyone from children to grandparents can be a challenging task. The NASA Langley Science Directorate Outreach and Communications Team has taken on the task to ensure that event participants have a worthwhile science experience through a series of educational tabletop games. This diverse group of educators, scientists, writers and graphic artists has been able to produce many games and activities perfect for public exposure and understanding. These games not only capture the imagination of the citizen scientists that visit the display, but they also allow them to learn the science behind many of the things that happen around them on a daily basis, many of which they take for granted. Teaching the public through games and short activities has proven to be a winning combination of efforts. In the development of any game or activity a great deal of consideration is given to "boiling down" the science concept or educational "take away." This step is where the diverse development group has proven to be invaluable. A final product developed by this team includes a review for science validity by a scientist, words written by a science writer, educational alignment by a science educator and design by a graphic designer. This process ensures that the game will attract the right group of people and have them leave understanding new science content. Games and activities generated in this fashion have been successful in the traditional classroom and informal education venues that this team routinely

    The national space programs have an historic opportunity to help solve the global-scale economic and environmental problems of Earth while becoming more effective at science through the use of space resources. Space programs will be more cost-effective when they work to establish a supply chain in space, mining and manufacturing then replicating the assets of the supply chain so it grows to larger capacity. This has become achievable because of advances in robotics and artificial intelligence. It is roughly estimated that developing a lunar outpost that relies upon and also develops the supply chain will cost about 1/3 or less of the existing annual budgets of the national space programs. It will require a sustained commitment of several decades to complete, during which time science and exploration become increasingly effective. At the end, this space industry will capable of addressing global-scale challenges including limited resources, clean energy, economic development, and preservation of the environment. Other potential solutions, including nuclear fusion and terrestrial renewable energy sources, do not address the root problem of our limited globe and there are real questions whether they will be inadequate or too late. While industry in space likewise cannot provide perfect assurance, it is uniquely able to solve the root problem, and it gives us an important chance that we should grasp. What makes this such an historic opportunity is that the space-based solution is obtainable as a side-benefit of doing space science and exploration within their existing budgets. Thinking pragmatically, it may take some time for policymakers to agree that setting up a complete supply chain is an achievable goal, so this paper describes a strategy of incremental progress. The most crucial part of this strategy is establishing a water economy by mining on the Moon and asteroids to manufacture rocket propellant. Technologies that support a water economy will play an

    The potential advantages displayed by biocatalytic processes for organic synthesis (such as exquisite selectivity under mild operating conditions), have prompted the increasing number of processes running on a commercial scale. However, biocatalysis is still a fairly underutilised technology. As a relatively new technology biocatalytic processes often do not immediately fulfil the required process metrics that are key for an economically and/or environmentally competitive process at an indust...

    The world of teaching and learning in the sciences in the Further Education (FE) sector is relatively under-researched. This study, across Scottish FE colleges, has sought to define some of the key landmarks in the area of the sciences, looking specifically at the students and their college experiences by means of surveys, interviews and curriculum intervention. The study started from the issue, observed personally, of students finding the learning of chemistry for a nursing course as being problematic. The main aim was to explore the key issues of science in FE, focussing on problems and successes. The attitudes, intellectual development and self perceptions of students have all been considered. The study explores the attitudes and self perceptions of over 800 learners studying the sciences at ten Scottish colleges. Demographic data, prior learning experiences and current learning attitudes to science and learning were obtained by means of questionnaires and interviews. Intellectual development data was obtained using an adaptation of the Perry Scheme of Intellectual Development. Further interview data were obtained with participating students at various stages of their learning experiences. The results show that, in general, students have varied backgrounds, aspirations and reasons for learning in FE. The learning experiences obtained at college were, in general, viewed to be very positive. In addition, the participating lecturers in Further Education college classes were viewed in a very positive light. In most cases, attitudes towards students learning experiences at college were viewed more positively than at school level, this being a greater emphasis for biology than chemistry. In addition, the role of the teacher at school level could be seen clearly in developing positive attitudes to science. In relating this back to school experience, it was found that those who had positive attitudes to science at school level, correlated more with intentions of

    in the science area, needs to be a long-term, grass-roots effort in all schools. We need to dedicate funding, and make time available for teachers to participate in long-term collaborative learning opportunities. Teachers want to observe each other and collaborate on lessons but, unless it becomes a priority of the school, it will not happen. Time must be dedicated throughout the day that allows small groups of teachers across the board to get together and share, learn, attempt new approaches, reflect and revise. Various forms of professional learning are available, and each school must choose the one that works for them. (5) The principal as the educational leader in the school needs to be more fully engaged with the learning process of the teachers and the students. The principal should not be viewed only as the evaluator of teachers, but as a collaborator of learning and teaching. Suggestions for further research include longitudinal studies of the impact on students of long term professional development of the teachers that specifically targets science content, inquiry and evidence--based discourse.

  11. Challenges of the science data processing, analysis and archiving approach in BepiColombo

    Martinez, Santa

    BepiColombo is a joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) to the planet Mercury. It comprises two separate orbiters: the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (MMO). After approximately 7.5 years of cruise, BepiColombo will arrive at Mercury in 2024 and will gather data during a 1-year nominal mission, with a possible 1-year extension. The approach selected for BepiColombo for the processing, analysis and archiving of the science data represents a significant change with respect to previous ESA planetary missions. Traditionally Instrument Teams are responsible for processing, analysing and preparing their science data for the long-term archive, however in BepiColombo, the Science Ground Segment (SGS), located in Madrid, Spain, will play a key role in these activities. Fundamental aspects of this approach include: the involvement of the SGS in the definition, development and operation of the instrument processing pipelines; the production of ready-to-archive science products compatible with NASA’s Planetary Data System (PDS) standards in all the processing steps; the joint development of a quick-look analysis system to monitor deviations between planned and executed observations to feed back the results into the different planning cycles when possible; and a mission archive providing access to the scientific products and to the operational data throughout the different phases of the mission (from the early development phase to the legacy phase). In order to achieve these goals, the SGS will need to overcome a number of challenges. The proposed approach requires a flexible infrastructure able to cope with a distributed data processing system, residing in different locations but designed as a single entity. For this, all aspects related to the integration of software developed by different Instrument Teams and the alignment of their development schedules will need to be

    The science teacher educators at a midwestern university set a goal to establish a collaborative relationship between themselves and representatives from the College of Arts & Sciences for the purpose of developing a middle childhood science education program. The coming together of these two faculties provided a unique opportunity to explore the issues and experiences that emerge as such a collaborative relationship is formed. In order to gain a holistic perspective of the collaboration, a phenomenological case study design and methods were utilized. The study took a qualitative approach to allow the experiences and issues to emerge in a naturalistic manner. The question, 'What are the issues and experiences that emerge as science teacher educators and science faculty attempt to form a collaborative relationship for the purpose of developing a middle childhood science teacher program?' was answered by gathering a wealth of data. These data were collected by means of semi-structured interviews, observations and written document reviews. An overall picture was painted of the case by means of heuristic, phenomenological, and issues analyses. The researcher followed Moustakas' Phases of Heuristic Research to answer the questions 'What does science mean to me?' and 'What are my beliefs about the issues guiding this case?' prior to completing the phenomenological analysis. The phenomenological analysis followed Moustakas' 'Modification of the Van Kaam Methods of Analysis of Phenomenological Data'. This inquiry showed that the participants in this study came to the collaboration for many different reasons and ideas about the purpose for such a relationship. The participants also had very different ideas about how such a relationship should be conducted. These differences combined to create some issues that affected the development of curriculum and instruction. The issues involved the lack of (a) mutual respect for the work of the partners, (b) understanding about the

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

  16. Quantitative Reasoning Learning Progressions for Environmental Science: Developing a Framework

    2013-01-01

    Full Text Available Quantitative reasoning is a complex concept with many definitions and a diverse account in the literature. The purpose of this article is to establish a working definition of quantitative reasoning within the context of science, construct a quantitative reasoning framework, and summarize research on key components in that framework. Context underlies all quantitative reasoning; for this review, environmental science serves as the context.In the framework, we identify four components of quantitative reasoning: the quantification act, quantitative literacy, quantitative interpretation of a model, and quantitative modeling. Within each of these components, the framework provides elements that comprise the four components. The quantification act includes the elements of variable identification, communication, context, and variation. Quantitative literacy includes the elements of numeracy, measurement, proportional reasoning, and basic probability/statistics. Quantitative interpretation includes the elements of representations, science diagrams, statistics and probability, and logarithmic scales. Quantitative modeling includes the elements of logic, problem solving, modeling, and inference. A brief comparison of the quantitative reasoning framework with the AAC&U Quantitative Literacy VALUE rubric is presented, demonstrating a mapping of the components and illustrating differences in structure. The framework serves as a precursor for a quantitative reasoning learning progression which is currently under development.

    Sundberg, Cheryl White

    The impact of collaboration via communication technology on follow-up to on-site professional development was the central focus of this hypothesis-generating study. The study used a combination of quantitative methodology and qualitative methodology. A convenient sample of 18 teachers was drawn from 208 teachers in an existing professional development program in science in a southeastern state. The statewide professional development program focused on energy education with a strong emphasis on using technology to enhance learning. Data sources included E-mail messages, lesson plans, photographs, workshop evaluations, surveys, and the report of an external reviewer. The study focused on two on-site workshops, February and June 2000 that were designed to model constructivist pedagogy and instruct teachers in effective utilization of computer-based laboratories in science classrooms. Follow-up to the on-site workshops was facilitated with several communication technologies (Internet, E-mail, telephone, and mail). The research found E-mail was the preferred mode for follow-up to on-site workshops because of the convenience of the medium. Barriers to effective distance professional development were time constraints, equipment failure, and lack of consistent Internet access to teachers in rural and under-served areas. Teacher characteristics of the sample, teacher efficacy, technical skill, experience, and constructivist pedagogy did not appear to impact the use of communication technologies as a means of follow-up to on-site professional development workshops. However, teacher efficacy might have negatively impacted effective implementation of calculator-based laboratory technology in the classroom. The study found E-mail was the most convenient and efficient way to facilitate follow-up to on-site professional development. Teacher characteristics (efficacy, technical skill, experience, and constructivist pedagogy) did not appear to impact the use of E-mail to facilitate
