The economy, national security, and standard of living of the United States depend heavily on adequate and reliable supplies of energy and mineral resources. Based on population and consumption trends, the Nation’s use of energy and minerals can be expected to grow, driving the demand for ever broader scientific understanding of resource formation, location, and availability. In addition, the increasing importance of environmental stewardship, human health, and sustainable growth places further emphasis on energy and mineral resources research and understanding. Collectively, these trends in resource demand and the interconnectedness among resources will lead to new challenges and, in turn, require cutting- edge science for the next generation of societal decisions. The long and continuing history of U.S. Geological Survey contributions to energy and mineral resources science provide a solid foundation of core capabilities upon which new research directions can grow. This science strategy provides a framework for the coming decade that capitalizes on the growth of core capabilities and leverages their application toward new or emerging challenges in energy and mineral resources research, as reflected in five interrelated goals.

The Role of the Nuclear Science and Technology in Hydrocarbon

International Nuclear Information System (INIS)

Eko Budi Lelono; Isnawati

2007-01-01

The development of the nuclear science and technology influences the method of hydrocarbon exploration as shown by the use of radioactive isotope to determine the absolute age of the rock. Traditionally, the age determination relies on the occurrence of index fossil, both micro and macro forms, to define the relative age of the rock. The absolute age is basically defined based on the calculation of the decay of the selected radioactive mineral. By referring to its absolute age, the rock (source rock or reservoir) can be precisely put in the certain stratigraphic level. On the other hand, the nuclear technology - so called NMR (Nuclear Magnetic Resonance) - is applied in the well exploration survey to measure the porosity and the permeability of the rock for predicting the existence of hydrocarbon. From the sedimentology view point, the nuclear technology is used in x ray diffraction (XRD) laboratory to identify mineral in the reservoir rock. In addition, it is also applied in scanning electron microscope (sem) laboratory for estimating the porosity of reservoir. These kinds of information are required by the exploration experts to create reservoir management. (author)

When technology, science and culture meet: insights from ancient Chinese technology

Science.gov (United States)

Lee, Yeung Chung

2017-10-01

This paper draws together two important agendas in science education. The first is making science education more inclusive such that students from non-Western or indigenous cultures can benefit from culturally relevant curricula. The second is integrating technology into the curriculum under the umbrella of Science-Technology-Society (STS) education to embrace the social aspects of science, with technology serving as a bridge. The advancement of the first agenda is hindered by the pursuance by both Western and non-Western societies of narrow cultural and practical goals without considering the development of science and technology from a cross-cultural perspective. The second agenda is limited by the misconception that technology is applied science, leading to the exclusion from STS discussions of pre-science or indigenous technologies developed by non-Western cultures. Through selected case studies of the evolution of Chinese traditional technologies and their interaction with science, this paper offers a perspective from the Far East, and argues for situating culturally responsive science education in broader historical and cross-cultural contexts to acknowledge the multi-cultural contributions to science and technology. A form of cross-cultural STS education is advanced, encompassing the cultural basis of technological developments, technology diffusion, interactions of traditional technology with science, and the potential development of traditional or indigenous technologies. This approach provides a bridge between the existing universal science education paradigm promoted in the West and the different forms of multi-cultural education advocated by indigenous science educators. To translate theory into practice, a conceptual framework is proposed in which the essential transdisciplinary knowledge base, curricular goals, and pedagogical approaches are embedded.

National Policies and strategies on science and technology for development.

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.

Science, technology, and pedagogy: Exploring secondary science teachers' effective uses of technology

Science.gov (United States)

Guzey, Siddika Selcen

Technology has become a vital part of our professional and personal lives. Today we cannot imagine living without many technological tools such as computers. For the last two decades technology has become inseparable from several areas, such as science. However, it has not been fully integrated into the field of education. The integration of technology in teaching and learning is still challenging even though there has been a historical growth of Internet access and available technology tools in schools (U.S. Department of Education, National Center for Education Statistics, 2006). Most teachers have not incorporated technology into their teaching for various reasons such as lack of knowledge of educational technology tools and having unfavorable beliefs about the effectiveness of technology on student learning. In this study, three beginning science teachers who have achieved successful technology integration were followed to investigate how their beliefs, knowledge, and identity contribute to their uses of technology in their classroom instruction. Extensive classroom observations and interviews were conducted. The findings demonstrate that the participating teachers are all intrinsically motivated to use technology in their teaching and this motivation allows them to enjoy using technology in their instruction and keeps them engaged in technology use. These teachers use a variety of technology tools in their instruction while also allowing students to use them, and they posit a belief set in favor of technology. The major findings of the study are displayed in a model which indicates that teachers' use of technology in classroom instruction was constructed jointly by their technology, pedagogy, and content knowledge; identity; beliefs; and the resources that are available to them and that the internalization of the technology use comes from reflection. The study has implications for teachers, teacher educators, and school administrators for successful technology

The use of technology into science learning encounters problems. One of the problem is teachers’ less technological pedagogical and content knowledge (TPACK) on the implementation of technology itself. The purpose of this study was to investigate science teachers’ experience in using digital technology into science classroom. Through this study science teachers’ technological knowledge (TK) and technological content knowledge (TCK) can be unpacked. Descriptive method was used to depict science teachers’ TK and TCK through questionnaire that consisted of 20 questions. Subjects of this study were 25 science teachers in Bandung, Indonesia. The study was conducted in the context of teacher professional training. Result shows that science teachers still have less TK, yet they have high TCK. The teachers consider characteristics of concepts as main aspect for implementing technology into science teaching. This finding describes teachers’ high technological content knowledge. Meanwhile, science teachers’ technological knowledge was found to be still low since only few of them who can exemplify digital technology that can be implemented into several science concept. Therefore, training about technology implementation into science teaching and learning is necessary as a means to improve teachers’ technological knowledge.

Application of remedy studies to the development of a soil washing pilot plant that uses mineral processing technology: a practical experience

International Nuclear Information System (INIS)

1999-01-01

Soil washing employing mineral processing technology to treat radionuclide-contaminated soils has been examined as a remedy alternative to the exclusive excavation, transportation, and disposal of the soil. Successful application depends on a thorough remedy study, employing a systematic tiered approach that is efficient, self-limiting, and cost effective. The study includes: (1) site and soil characterization to determine the basic mineral and physical properties of both the soil and contaminants and to identify their relative associations; (2) treatment studies to evaluate the performance of process units for contaminant separation; (3) conceptual process design to develop a treatment pilot plant; and (4) engineering design to construct, test, and optimize the actual full-scale plant. A pilot plant using soil washing technology for the treatment of radium-contaminated soil was developed, tested, and demonstrated. The plant used particle-size separation to produced a remediated product that represented approximately 50% of the contaminated soil. Subsequently, it was modified for more effective performance and application to soil with alternate characteristics; it awaits further testing. The economic analysis of soil washing using the pilot plant as a model indicates that a remedy plan based on mineral processing technology is very competitive with the traditional alternative employing excavation, transportation, and disposal exclusively, even when disposal costs are modest or when recovery of remediated soil during treatment is low. This paper reviews the tiered approach as it applies to mineral processing technology to treat radionuclide-contaminated soils and a pilot plant developed to test the soil washing process.

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

These requirements are evident in the need to optimise time and efforts in activities to do with health. When e-Science focuses on the collaborative handling of all the information generated in clinical medicine and health, e-Health is the result. Scientists are taking increasing interest in an emerging technology – Grid Information Technology – that may offer a solution to their current needs. The current work aims to survey how e-Science is using this technology all around the world. We also argue that the technology may provide an ideal solution for the new challenges facing e-Health and Life Science.

Nuclear technology and mineral recovery

International Nuclear Information System (INIS)

Stewart, Richard M.; Niermeyer, Karl E.

1970-01-01

The particular aspect of nuclear technology most applicable to the mineral field, as has been pointed out by various authors, is nuclear blasting. The prime target for this nuclear blasting has usually been a large disseminated deposit of copper mineralization which, because of large dimensions, employs the nuclear devices most effectively. From the work of the AEC we know that the larger nuclear devices fragment rock for a lower energy cost per unit of ground broken than do smaller nuclear devices or chemical explosives. A mineralized deposit near the surface is usually not amenable to nuclear fragmentation, nor are the more deeply buried thin deposits. Also, one would not anticipate fragmenting a zone of excessively erratic mineralization with nuclear devices. Many of our mineralized areas would be eliminated using the above criteria, so at this point you are well aware that my self-imposed limitation is to nuclear blasting and large disseminated copper deposits. As with most other industries, copper mining faces rising costs and greater demands for its products. One of the rising cost features peculiar to extractive industries is the reliance placed on production from lower grade deposits as the higher grade deposits are depleted. As the grade or metal content of an orebody decreases more material must be handled to produce a given amount of metal. The increased volume of ore which must be handled as the grade declines requires expansion of facilities and higher capital expenditures. Expansion of facilities for mining, milling, and concentrating of the ore increases the per unit capital cost of the end product--copper. Increased copper consumption will aggravate this situation with demand for more metal, much of which will have to be obtained from lower grade deposits. As the higher grade deposits are depleted, future production will come from those deposits which cannot be exploited economically today. Most familiar of the proposed new methods for copper mining

Multi Blending Technology (MBT): mineral processing method for increasing added value of marginal reserve

Science.gov (United States)

Agustinus, E. T. S.

2018-02-01

Indonesia's position on the path of ring of fire makes it rich in mineral resources. Nevertheless, in the past, the exploitation of Indonesian mineral resources was uncontrolled resulting in environmental degradation and marginal reserves. Exploitation of excessive mineral resources is very detrimental to the state. Reflecting on the occasion, the management and utilization of Indonesia's mineral resources need to be good in mining practice. The problem is how to utilize the mineral reserve resources effectively and efficiently. Utilization of marginal reserves requires new technologies and processing methods because the old processing methods are inadequate. This paper gives a result of Multi Blending Technology (MBT) Method. The underlying concept is not to do the extraction or refinement but processing through the formulation of raw materials by adding an additive and produce a new material called functional materials. Application of this method becomes important to be summarized into a scientific paper in a book form, so that the information can spread across multiple print media and become focused on and optimized. This book is expected to be used as a reference for stakeholder providing added value to environmentally marginal reserves in Indonesia. The conclusions are that Multi Blending Technology (MBT) Method can be used as a strategy to increase added values effectively and efficiently to marginal reserve minerals and that Multi Blending Technology (MBT) method has been applied to forsterite, Atapulgite Synthesis, Zeoceramic, GEM, MPMO, SMAC and Geomaterial.

Clune, T.; Seablom, M. S.; Moe, K.

2012-12-01

The NASA Earth Science Technology Office (ESTO) regularly makes investments for nurturing advanced concepts in information technology to enable rapid, low-cost acquisition, processing and visualization of Earth science data in support of future NASA missions and climate change research. In 2012, the National Research Council published a mid-term assessment of the 2007 decadal survey for future spacemissions supporting Earth science and applications [1]. The report stated, "Earth sciences have advanced significantly because of existing observational capabilities and the fruit of past investments, along with advances in data and information systems, computer science, and enabling technologies." The report found that NASA had responded favorably and aggressively to the decadal survey and noted the role of the recent ESTO solicitation for information systems technologies that partnered with the NASA Applied Sciences Program to support the transition into operations. NASA's future missions are key stakeholders for the ESTO technology investments. Also driving these investments is the need for the Agency to properly address questions regarding the prediction, adaptation, and eventual mitigation of climate change. The Earth Science Division has championed interdisciplinary research, recognizing that the Earth must be studied as a complete system in order toaddress key science questions [2]. Information technology investments in the low-mid technology readiness level (TRL) range play a key role in meeting these challenges. ESTO's Advanced Information Systems Technology (AIST) program invests in higher risk / higher reward technologies that solve the most challenging problems of the information processing chain. This includes the space segment, where the information pipeline begins, to the end user, where knowledge is ultimatelyadvanced. The objectives of the program are to reduce the risk, cost, size, and development time of Earth Science space-based and ground

Rock and mineral magnetism

CERN Document Server

O’Reilly, W

1984-01-01

The past two decades have witnessed a revolution in the earth sciences. The quantitative, instrument-based measurements and physical models of. geophysics, together with advances in technology, have radically transformed the way in which the Earth, and especially its crust, is described. The study of the magnetism of the rocks of the Earth's crust has played a major part in this transformation. Rocks, or more specifically their constituent magnetic minerals, can be regarded as a measuring instrument provided by nature, which can be employed in the service of the earth sciences. Thus magnetic minerals are a recording magnetometer; a goniometer or protractor, recording the directions of flows, fields and forces; a clock; a recording thermometer; a position recorder; astrain gauge; an instrument for geo­ logical surveying; a tracer in climatology and hydrology; a tool in petrology. No instrument is linear, or free from noise and systematic errors, and the performance of nature's instrument must be assessed and ...

Trubetskoy, KN; Galchenko, YuP; Eremenko, VA

2018-03-01

The paper sets forth a theoretical framework for the strategy of the radically new stage in development of geotechnologies under conditions of rapidly aggravating environmental crisis of the contemporary technocratic civilization that utilizes the substance extracted from the lithosphere as the source of energy and materials. The authors of the paper see the opportunity to overcome the conflict between the techno- and bio-spheres in the area of mineral raw materials by means of changing the technological paradigm of integrated mineral development by implementing nature-like technologies oriented to the ideas and methods of converging resources of natural biota as the object of the environmental protection and geotechnologies as the major source of ecological hazards induced in the course of development of mineral resources of lithosphere.

Mineral supply constraints necessitate a global policy response

Science.gov (United States)

Nickless, Edmund

2016-04-01

Adoption on 12 December 2015 of The Paris Agreement, the first universal climate agreement, suggests that nations will invest in infrastructures for renewable energy sources paving the way to a global low-carbon society. These large-scale changes will require vast amounts of metals and minerals. Regardless of whether known supplies are enough to meet demand in the near future, efforts must be made now to forestall unpredictable yet inevitable supply shortages in the decades to come, shortages that would dramatically impact the building of additional generation and distribution capacity, and deployment of low-carbon technology. But in response to the current downturn in commodity prices, the global mining industry is downsizing and reducing investment in the new exploration, putting at risk future security of supply. Mining and climate change are inextricably linked; the new adaptive technologies needed to tackle climate change depend on extraction of minerals and metals. An interdisciplinary group supported by the International Union of Geological Sciences, the International Council for Science Unions and UNESCO proposes measures to avert the looming minerals crisis that is developing in the context of current recycling capacity and exploration trends. Our immediate goal is to stimulate discussion of supply constraints using available data on mineral reserves. We build on recent discussions of supply risk and criticality with a focus on the source of primary resources over the next two to three decades when the availability of metals for recycling will remain low. Current massive production of iron ore and other such commodities despite record low prices indicates a failure of the traditional supply and demand constraints. Broader discussions of metal and mineral supply beyond current criticality are needed given the pace of technological and demographic change as well as rapid development spurts. Furthermore, accessible mineral deposits are irregularly distributed

White paper on science and technology, 1995. Fifty years of postwar science and technology in Japan

International Nuclear Information System (INIS)

1995-07-01

This August marks 50 years since the end of World War II. Japan emerged from the ruins to overcome the post-war devastation to achieve a high level of economic growth and become the second largest economy in the world. Science and technology have played major roles as a driving force behind this quest for prosperity. However, it seems as though true prosperity is not necessarily being enjoyed by citizens of Japan today. Japan is becoming an aging society. To realize a truly rich and prosperous society in which people can live comfortably, it is important to further raise the level of science and technology. It is also necessary to ensure this development by revitalizing the economy, and to continue to utilize science and technology as an endless resource to create assets for society as a whole which will be inherited by future generations. With this viewpoint in mind, this White Paper looks back on Japan's scientific and technological development over the last 50 years, and considers the future of science and technology with a view toward realizing the true prosperity for its people. It is our hope that this White Paper will be helpful for considering the scientific and technological activities needed to bring about a Japan whose people are truly prosperous, and we will, as a government, continually increase our efforts toward the promotion of science and technology.

Micron to Mine: Synchrotron Science for Mineral Exploration, Production, and Remediation

Science.gov (United States)

Banerjee, N.; Van Loon, L.; Flynn, T.

2017-12-01

Synchrotron science for mineral exploration, production, and remediation studies is a powerful tool that provides industry with relevant micron to macro geochemical information. Synchrotron micro X-ray fluorescence (SR-µXRF) offers a direct, high-resolution, rapid, and cost-effective chemical analysis while preserving the context of the sample by mapping ore minerals with ppm detection limits. Speciation of trace and deleterious elements can then be probed using X-ray absorption near-edge structure (XANES) spectroscopy. Large-scale (tens of cm) µXRF mapping and XANES analysis of samples collected at various mine locations have been undertaken to address questions regarding mineralization history to develop novel trace element exploration vectors. This information provides integral insights into trace element associations with ore minerals, local redox conditions responsible for mineralization, and mineralizing mechanisms. Gold is commonly intimately associated with sulfide mineralization (e.g., pyrite, arsenopyrite, etc.) and is present both as inclusions and filling fractures in sulfide grains. Gold may also occur as nanoparticles and/or in the sulfide mineral crystal lattice, known as "invisible gold". Understanding the nature and distribution of invisible gold in ore is integral to processing efficiency. The high flux and energy of a synchrotron light source allows for the detection of invisible gold by µXRF, and can probe its nature (metallic Au0 vs. lattice bound Au1+) using XANES spectroscopy. The long-term containment and management of arsenic is necessary to protect the health of both humans and the environment. Understanding the relationship of arsenic mineralization to gold deposits can lead to more sophisticated planning for mineral processing and the eventual storage of gangue materials. µXANES spectroscopy is an excellent tool for determining arsenic speciation within the context of the sample. Mineral phases such as arsenopyrite, scorodite, and

The continuing growth in mineral extraction entails an increase in industrial waste, which in turn has a negative impact on the environment. Rubber-tired vehicles, in which the tires wear colossally, is mainly used as a transport for loading, unloading, transportation and other types of work in the extraction of solid minerals. The used tires are not disposed in any way, but are stored in special areas where harmful toxic substances are emitted under the influence of ultraviolet rays. Therefore, a decision was made to find a method for utilization and rational use of industrial waste in the road construction sector. The operating temperature of composite rubber-bituminous binders based on rubber crumb from the used automobile tires is estimated in this paper, which is necessary for assigning technological parameters of production and laying of asphalt-concrete mixtures produced on their basis. It is established that composite rubber-bituminous binders based on rubber chips from the used automobile tires, produced according to the two-stage technology, have the same viscosity as the original petroleum bitumen, at a temperature increased by 20°C.

The Mineral Question: How Energy and Technology Will Determine the Future of Mining

International Nuclear Information System (INIS)

Bardi, Ugo

2013-01-01

Almost 150 years after that Jevons (1866) published his paper “The Coal Question” a debate on mineral depletion has been ongoing between two main schools of thought: one that sees depletion as an important problem for the near future and another that sees technology and human ingenuity as making depletion only a problem for the remote future. Today, however, we have created intellectual tools that permit us to frame the problem on the basis of physical factors, in particular on the basis of thermodynamics. The present paper examines the problem of mineral depletion from a broad viewpoint, with a specific view on the role of energy in the mining and production processes. The conclusion is that energy is a fundamental factor in determining how long we can expect the supply of mineral resources to last at the present prices and production levels. The rapid depletion of our main energy resources, fossil fuels, is creating a serious supply problem that is already being felt in terms of high prices of all mineral commodities. Technology can mitigate the problem, but not solve it. In a non-remote future, the world’s industrial system will have to undergo fundamental changes in order to adapt to a reduced supply of mineral commodities.

The clay materials have led to numerous applications in the field of public health (del Hoyo, 2007; Volzone, 2007) having been demonstrated its effectiveness as adsorbents of all contaminants. Some biodegradable materials are used for for adsorption of chemical contaminants: lignins (Valderrabano et al., 2008) and also clays and clay minerals, whose colloidal properties, ease of generating structural changes, abundance in nature, and low cost make them very suitable for this kind of applications. Among the strategies used at present to preserve the quality of the water and this way to diminish the environmental risk that supposes the chemical pollution, stands out the use of adsorbents of under cost, already they are natural or modified, to immobilize these compounds and to avoid the pollution of the water with the consequent reduction of environmental and economic costs Thanks to the development of the science and the technology of the nourishment in the last 50 years, there have revealed itself several new substances that can fulfill beneficial functions in the food, and these substances, named food additives, are today within reach of all. The food additives recover a very important role in the complex nourishing supply. The additives fulfill several useful functions in the food, which often we give for sat. Nevertheless the widespread use of food additives in the food production also influences the public health. The food industries, which are very important for the economy, spill residues proved from its activity that they have to be controlled to evaluate the environmental impact and to offer the necessary information about the quantitative evaluation of the chemical risk of the use of food additives for the public health. We have studied the adsorption of several contaminants by natural or modified clays, searching their interaction mechanisms and the possible recycling of these materials for environmental purposes and prevention of the health.

Promising Technologies of Mining and Processing of Solid Minerals

Directory of Open Access Journals (Sweden)

Shabaev Sergey

2017-01-01

Full Text Available The continuing growth in mineral extraction entails an increase in industrial waste, which in turn has a negative impact on the environment. Rubber-tired vehicles, in which the tires wear colossally, is mainly used as a transport for loading, unloading, transportation and other types of work in the extraction of solid minerals. The used tires are not disposed in any way, but are stored in special areas where harmful toxic substances are emitted under the influence of ultraviolet rays. Therefore, a decision was made to find a method for utilization and rational use of industrial waste in the road construction sector. The operating temperature of composite rubber-bituminous binders based on rubber crumb from the used automobile tires is estimated in this paper, which is necessary for assigning technological parameters of production and laying of asphalt-concrete mixtures produced on their basis. It is established that composite rubber-bituminous binders based on rubber chips from the used automobile tires, produced according to the two-stage technology, have the same viscosity as the original petroleum bitumen, at a temperature increased by 20°C.

Statement of the problem. As future citizens, students will have the enormous responsibility of making decisions that will require an understanding of the interaction of science and technology and its interface with society. Since many societal issues today are grounded in science and technology, learning science in its social context is vital to science education reform. Science-Technology-Society (STS) has been strongly identified with meeting this goal, but despite its benefits, putting theory into practice has been difficult. Research design and methodology. The purpose of this study was to explore teacher beliefs about teaching science through STS. The following broad research questions guided the study: (1) What are the participants' initial beliefs about teaching science through STS? (2) What beliefs emerge as participants reflect upon and share their STS instructional experiences with their peers? A social constructivist theoretical framework was developed to plan interactions and collect data. Within this framework, a qualitative methodology was used to interpret the data and answer the research questions. Three provisionally certified science teachers engaged in a series of qualitative tasks including a written essay, verbal STS unit explanation, reflective journal writings, and focus group interviews. After implementing their STS unit, the participants engaged in meaningful dialogue with their peers as they reflected upon, shared, and constructed their beliefs. Conclusions. The participants strongly believed in STS as a means for achieving scientific and technological literacy, developing cognition, enhancing scientific habits of mind and affective qualities, and fostering citizen responsibility. Four major assertions were drawn: (a) Participants' initial belief in teaching for citizen responsibility did not fully align with practice, (b) Educators at the administrative level should be made aware of the benefits of teaching science through STS, (c

Politicizing science: conceptions of politics in science and technology studies.

Science.gov (United States)

Brown, Mark B

2015-02-01

This essay examines five ideal-typical conceptions of politics in science and technology studies. Rather than evaluating these conceptions with reference to a single standard, the essay shows how different conceptions of politics serve distinct purposes: normative critique, two approaches to empirical description, and two views of democracy. I discuss each conception of politics with respect to how well it fulfills its apparent primary purpose, as well as its implications for the purpose of studying a key issue in contemporary democratic societies: the politicization of science. In this respect, the essay goes beyond classifying different conceptions of politics and also recommends the fifth conception as especially conducive to understanding and shaping the processes whereby science becomes a site or object of political activity. The essay also employs several analytical distinctions to help clarify the differences among conceptions of politics: between science as 'political' (adjective) and science as a site of 'politics' (noun), between spatial-conceptions and activity-conceptions of politics, between latent conflicts and actual conflicts, and between politics and power. The essay also makes the methodological argument that the politics of science and technology is best studied with concepts and methods that facilitate dialogue between actors and analysts. The main goal, however, is not to defend a particular view of politics, but to promote conversation on the conceptions of politics that animate research in social studies of science and technology.

Science education often adopts a narrow view of science that assumes the lay public is ignorant, which seemingly justifies a science education limited to a promotional narrative of progress in the form of scientific knowledge void of meaningful social context. We propose that to prepare students as future concerned citizens of a technoscientific society, science education should be informed by science, technology, and society (STS) perspectives. An STS-informed science education, in our view, will include the following curricular elements: science controversy education, gender issues, historical perspective, and a move away from a Eurocentric view by looking into the distinctive patterns of other regional (in this case of Taiwan, East Asian) approaches to science, technology, and medicine. This article outlines the significance of some major STS studies as a means of illustrating the ways in which STS perspectives can, if incorporated into science education, enhance our understanding of science and technology and their relationships with society.

which enables him to continuous innovation. Different materials are used in the adsorption and improvement and design of new adsorbents, most of whom remain under patent, so they do not know the procedures and products used, but in all cases the safety and / or biodegradability of materials used is an important issue in their choice for environmental applications. In regard to materials, safe and low cost must be mentioned clays and clay minerals, whose colloidal properties, ease of generating structural changes, abundance in nature, and low cost make them very suitable for adsorption chemical contaminants. We proposed to use these materials to show the different aspects for the study of the Science Materials. References -del Hoyo, C. (2007b). Layered Double Hydroxides and human health: An overview.

Conceptualizing Student Affect for Science and Technology at the Middle School Level: Development and Implementation of a Measure of Affect in Science and Technology (MAST)

Science.gov (United States)

Romine, William L.; Sadler, Troy D.; Wulff, Eric P.

2017-10-01

We describe the development of the Measure of Affect in Science and Technology (MAST), and study its usefulness for measuring science affect in middle school students via both classical and Rasch measurement perspectives. We then proceed to utilize the measurement structure of the MAST to understand how middle school students at varying levels of affect express their interest and attitudes toward science and technology and gender differences in how students express their affect. We found that affect in science and technology comprises a main dimension, science interest, and four peripheral dimensions: interest in careers in science and technology, attitudes toward science, and interest in attending science class. Of these, careers in science and technology carry the highest affective demand. While males showed higher levels of personal and situational interest in science, a greater interest in careers in science and technology was the biggest contributor to males' higher affect toward science and technology. We argue that whether the MAST is used as a measure of a single construct or multiple subconstructs depends upon specific research or evaluation goals; however, both uses of the MAST yield measures which produce valid inferences for student affect.

2014-01-01

To review the existing literature pertaining to the current learning technologies available in radiologic science education and how to implement those technologies. Only articles from peer-reviewed journals and scholarly reports were used in the research for this review. The material was further restricted to those articles that emphasized using new learning technologies in education, with a focus on radiologic science education. Teaching in higher education is shifting from a traditional classroom-based lecture format to one that incorporates new technologies that allow for more varied and diverse educational models. Radiologic technology educators must adapt traditional education delivery methods to incorporate current technologies. Doing so will help engage the modern student in education in ways in which they are already familiar. As students' learning methods change, so must the methods of educational delivery. The use of new technologies has profound implications for education. If implemented properly, these technologies can be effective tools to help educators.

While access to computers, other technologies, and cyber-enabled resources that could be leveraged for enhancing student learning in science is increasing, generally it has been found that teachers use technology more for administrative purposes or to support traditional instruction. This use of technology, especially to support traditional instruction, sits in opposition to most recent standards documents in science education that call for student involvement in evidence-based sense-making activities. Many see technology as a potentially powerful resource that is reshaping society and has the potential to do the same in science classrooms. To consider the promise of technology in science classrooms, this research investigated the impact of a professional development project focused on enhancing teacher and student learning by using information and communication technologies (ICTs) for engaging students in reformed-based instruction. More specifically, these findings revealed positive teacher outcomes with respect to reformed-based and technology-supported instruction and increased ICT and new literacies skills. When considering students, the findings revealed positive outcomes with respect to ICT and new literacies skills and student achievement in science.

IMPROVING THE EFFICIENCY OF MINERAL WOOL SLABS TECHNOLOGY

Directory of Open Access Journals (Sweden)

Perfilov Vladimir Aleksandrovich

2016-03-01

Full Text Available The use of thermal insulation materials is an effective method to create an insulating envelope of a building, as well as to reduce energy costs and increase the durability of building structures. The properties of stone wool products and their operational durability is largely determined by the conditions of formation of the mineral wool carpet, uniform distribution of binder and its curing and the heat treatment conditions. Most domestic technologies are aimed at the production of mineral wool products with volume-oriented structure, which is formed using special units: spreader and corrugator placed in a production line. The next step to obtain the optimum structures is the production of dual density slabs. The denser upper layer receives mechanical loads caused by the operating conditions; the lower, less dense, but more thick layer performs the main function - insulation. The dual density slabs are produced on standard lines supplemented with a special unit, which is located in front of the heat treatment camera. Optimization of heat treatment parameters and prediction of the properties of materials is performed using software package.

Technology Use in Science Instruction (TUSI): Aligning the Integration of Technology in Science Instruction in Ways Supportive of Science Education Reform

Science.gov (United States)

Campbell, Todd; Abd-Hamid, Nor Hashidah

2013-08-01

This study describes the development of an instrument to investigate the extent to which technology is integrated in science instruction in ways aligned to science reform outlined in standards documents. The instrument was developed by: (a) creating items consistent with the five dimensions identified in science education literature, (b) establishing content validity with both national and international content experts, (c) refining the item pool based on content expert feedback, (d) piloting testing of the instrument, (e) checking statistical reliability and item analysis, and (f) subsequently refining and finalization of the instrument. The TUSI was administered in a field test across eleven classrooms by three observers, with a total of 33 TUSI ratings completed. The finalized instrument was found to have acceptable inter-rater intraclass correlation reliability estimates. After the final stage of development, the TUSI instrument consisted of 26-items separated into the original five categories, which aligned with the exploratory factor analysis clustering of the items. Additionally, concurrent validity of the TUSI was established with the Reformed Teaching Observation Protocol. Finally, a subsequent set of 17 different classrooms were observed during the spring of 2011, and for the 9 classrooms where technology integration was observed, an overall Cronbach alpha reliability coefficient of 0.913 was found. Based on the analyses completed, the TUSI appears to be a useful instrument for measuring how technology is integrated into science classrooms and is seen as one mechanism for measuring the intersection of technological, pedagogical, and content knowledge in science classrooms.

Science teachers' perceptions of the effectiveness of technology in the laboratories: Implications for science education leadership

Science.gov (United States)

Yaseen, Niveen K.

2011-12-01

The purpose of this study was to identify science teachers' perceptions concerning the use of technology in science laboratories and identify teachers' concerns and recommendations for improving students' learning. Survey methodology with electronic delivery was used to gather data from 164 science teachers representing Texas public schools. The data confirmed that weaknesses identified in the 1990s still exist. Lack of equipment, classroom space, and technology access, as well as large numbers of students, were reported as major barriers to the implementation of technology in science laboratories. Significant differences were found based on gender, grade level, certification type, years of experience, and technology proficiency. Females, elementary teachers, traditionally trained teachers, and less experienced teachers revealed a more positive attitude toward the use of technology in science laboratories. Participants in this study preferred using science software simulations to support rather than replace traditional science laboratories. Teachers in this study recommended professional development programs that focused on strategies for a technology integrated classroom.

Technology transfer of nuclear techniques and nucleonic control systems in the mineral industry

International Nuclear Information System (INIS)

1990-11-01

Among the many beneficial applications of radiation and radioisotopes in industry which are now well established in advanced countries, the applications of nuclear techniques and nucleonic control systems in the mineral industry have great potential for developing Member States. The use of nucleonic on-stream analyzers in the coal industry has resulted in enormous technical and economic benefits in addition to minimization of environmental pollution. Large savings have also resulted from the use of such analyzers in the processing of other minerals. Nuclear borehole logging techniques have demonstrated great potential in oil and gas evaluation. Radiotracer investigations have led to process optimisation and trouble shooting in various stages in ore processing and metallurgy. Though the technical and economic benefits of applications of nuclear techniques in the mineral industry are well recognised, technology transfer in these areas has been hampered by a variety of factors. In order to review the status and trends in nuclear techniques and nucleonic control systems in the mineral industry and the problems and considerations in their technology transfer to developing Member States, the IAEA convened an Advisory Group Meeting in Bombay, India, 15-19 January 1990. The present publication is based on the 7 contributions presented at this meeting. A separate abstract was prepared for each of these papers. Refs, figs and tabs

Technology-Enhanced Science Partnership Initiative: Impact on Secondary Science Teachers

Science.gov (United States)

Ng, Wan; Fergusson, Jennifer

2017-07-01

The issue of student disengagement in school science continues to pose a threat to lifting the participation rates of students undertaking STEM courses and careers in Australia and other countries globally. In Australia, several science initiatives to reverse the problem have been funded over the last two decades. Many of these initiatives involve partnerships with scientists, science educators and with industries, as is the case in this paper. The research in this paper investigated a recent partnership initiative between secondary science teachers, scientists and an educational technology company to produce science e-modules on adaptive learning platforms, enabling students to engage in personalised, inquiry-based learning and the investigation of real-world problems. One of the objectives of the partnership project was to build theoretical and pedagogical skills in teachers to deliver science by exposing them to new ways of engaging students with new digital tools, for example analytics. Using a mixed methods approach, the research investigated science teachers' pedagogical involvement in the partnership project and their perceptions of the project's impact on their teaching and students' learning. The findings indicate that the teachers believed that new technology could enhance their teaching and students' learning and that while their students were motivated by the online modules, there was still a need for scaffolding for many of the students. The effectiveness of this would depend on the teachers' ability to internalise the new technological and content knowledge resulting from the partnership and realign them with their existing pedagogical framework. The research is significant in identifying elements for successful partnership projects as well as challenges that need to be considered. It is significant in facilitating continuous discourse about new evidence-based pedagogical approaches to science education in engaging students to learn STEM subjects in a

Science Fiction at the Far Side of Technology

DEFF Research Database (Denmark)

Johansen, Mikkel Willum

2017-01-01

This book explores what science fiction can tell us about the human condition in a technological world (with the dilemma's and consequences that this entails) and also engages with the genre at points where we apparently find it on the far side of science, technology or human existence. As such......, it is the result of the joint efforts of scholars and scientists from various disciplines. While some of the contributors to this volume have been working professionally with science fiction for some time, others are newcomers who bring perspectives from their own field of specialization to the study of this genre....... Although a scholarly work, this book is also designed to be accessible to a general audience that has an interest in science fiction as well as a broader academic audience. Aspiring (or experienced) science fiction writers may be interested in reading critical assessments of the science and technology...

2011-12-01

This study investigated the effectiveness of a guided inquiry integrated with technology, in terms of female middle-school students' attitudes toward science/scientists and content knowledge regarding selective science concepts (e.g., Greenhouse Effect, Air/Water Quality, Alternative Energy, and Human Health). Thirty-five female students who were entering eighth grade attended an intensive, 1-week Inquiry-Based Science and Technology Enrichment Program which used a main theme, "Green Earth Enhanced with Inquiry and Technology." We used pre- and post-attitude surveys, pre- and post-science content knowledge tests, and selective interviews to collect data and measure changes in students' attitudes and content knowledge. The study results indicated that at the post-intervention measures, participants significantly improved their attitudes toward science and science-related careers and increased their content knowledge of selected science concepts ( p < .05).

Technology thrusts for future Earth science applications

Science.gov (United States)

Habib, Shahid

2001-02-01

This paper presents NASA's recent direction to invest in the critical science instrument and platform technologies in order to realize more reliable, frequent and versatile missions for future Earth Science measurements. Historically, NASA's Earth Science Enterprise has developed and flown science missions that have been large in size, mass and volume. These missions have taken much longer to implement due to technology development time, and have carried a large suite of instruments on a large spacecraft. NASA is now facing an era where the budget for the future years is more or less flat and the possibility for any major new start does not vividly appear on the horizon. Unfortunately, the scientific measurement needs for remote sensing have not shrunk to commensurate with the budget constraints. In fact, the challenges and scientific appetite in search of answers to a score of outstanding questions have been gradually expanding. With these factors in mind, for the last three years NASA has been changing its focus to concentrate on how to take advantage of smaller missions by relying on industry, and minimizing the overall mission life cycle by developing technologies that are independent of the mission implementation cycle. The major redirection of early investment in the critical technologies should eventually have its rewards and significantly reduce the mission development period. Needless to say, in the long run this approach should save money, minimize risk, promote or encourage partnering, allow for a rapid response to measurement needs, and enable frequent missions making a wider variety of earth science measurements. This paper gives an overview of some of the identified crucial technologies and their intended applications for meeting the future Earth Science challenges.

This paper presents NASA's recent direction to invest in the critical science instrument and platform technologies in order to realize more reliable, frequent and versatile missions for future Earth Science measurements. Traditionally, NASA's Earth Science Enterprise has developed and flown science missions that have been large in size, weight and volume. These missions have taken much longer implementation due to technology development time and have carried a large suite of instruments on a large-size spacecraft. NASA is also facing an era where the budget for the future years is more or less flat and the possibility for any major new start does not vividly appear on the horizon. Unfortunately, the scientific goals have not shrunk to commensurate with the budget constraints. In fact, the challenges and scientific appetite in search of answers to a score of outstanding questions have been gradually expanding. With these factors in mind, for the last three years NASA has been changing its focus to concentrate on how to take advantage of smaller missions by relying on industry, and minimizing the overall life cycle by infusing technologies that are being developed independently of any planned mission's implementation cycle. The major redirection of early investment in the critical technologies should have its rewards and significantly reduce the mission development period. Needless to say, in the long run this approach should save money, minimize risk, promote or encourage partnering, and allow for more frequent missions or earth science measurements to occur. This paper gives an overview of some of the identified crucial technologies and their intended applications for meeting the future Earth Science challenges.

Remote mineral mapping using AVIRIS data at Summitville, Colorado and the adjacent San Juan Mountains

Science.gov (United States)

King, Trude V. V.; Clark, Roger N.; Ager, Cathy; Swayze, Gregg A.

1995-01-01

We have demonstrated the unique utility of imaging spectroscopy in mapping mineral distribution. In the Summitville mining region we have shown that the mine site does not contribute clay minerals to the Alamosa River, but does contribute Fe-bearing minerals. Such minerals have the potential to carry heavy metals. This application illustrates only one specific environmental application of imaging spectroscopy data. For instance, the types of minerals we can map with confidence are those frequently associated with environmental problems related to active and abandoned mine lands. Thus, the potential utility of this technology to the field of environmental science has yet to be fully explored.

Ethics, science and technology

Full Text Available The article aims at thinking the relation between ethics, science and technology, emphasising the problem of their re-linking, after the split into judgements of fact and judgements of value, which happened in the beginning of modern times. Once the warlike Aristocracy's ethics and the saint man's moral are examined, one tries to outline the way by taking as a reference the ethics of responsibility, whose prototype is the wise man's moral, which disappeared in the course of modern times, due to the fragmentation of knowing and the advent of the specialist. At the end of the study, the relation between ethics and metaphysics is discussed, aiming at adjusting the anthropological question to the cosmological perspective, as well as at providing the bases of a new humanism, objectifying the humanising of technique and the generation of a new man, literate at science, technology and the humanities.

This is a special lecture at the 30th anniversary of JICST. To develop science-and-te chnology-oriented society it is important to evaluate and select infinite information resources on science and technology, and to reorganize and apply them. This also relates to humanity. For the future, we have to establish scientific ethics that can exceed the expedience of science and technology. To be concrete, we have to create new industrial value that recovers and reclaims natural resources which men had wasted so far, and we have to establish a new technology to distribute maldistributed industrial benefits equally. And then, the selfcontrol of the human aiming at the harmony of nature and man will secure human liberty, and it will be done by the good function of man's brain.

Microprobe to closely examine minerals

International Nuclear Information System (INIS)

2006-01-01

The University of South Australia will develop synchrotron-based technology that can determine the structure and chemical composition of mineral samples at microscopic levels. The planned multi-analysis synchrotron X-ray facility Beam-line 11 is for implementing on the Australian Synchrotron. UniSA's Applied Centre for Structural and Synchrotron Studies (ACeSSS) will use Beamline 11 to shed new light on factors that constrain recoveries of copper and gold from typical copper ores. ACeSSS director Professor Andrea Gerson is working with an international team and the Australian Synchrotron on the design of Beamline 11. According to Gerson, there is scope to improve processing and/or increase recoveries in copper, gold and valueless pyrite either through separation, smelting, leaching or electro-processing. Using synchrotron technology, researchers will determine the structure and chemical composition of mineral samples to understand the fundamental behaviour of these materials in order to identify process and : environmental benefits. Three different strategies will be employed: tracing the movement of gold through the mineral processing chain to optimise and increase gold recovery; examining the surface layers formed when copper is leached from the mineral, chalcopyrite, to enhance the understanding of this surface layer formation and ultimately maximise cop-per recovery; and improving environmental remediation by understanding the mineralisation process during acid-rock drainage. ACeSSS will work with the minerals and environmental remediation sectors, building on the I establishment of the Cooperative Research Centre for Contamination Assessment and Remediation of the Environment, and cementing close collaboration with UniSA's Ian Wark Research Institute.

Physics Problems Based on Up-to-Date Science and Technology.

Science.gov (United States)

Folan, Lorcan M.; Tsifrinovich, Vladimir I.

2007-03-01

We observe a huge chasm between up-to-date science and undergraduate education. The result of this chasm is that current student interest in undergraduate science is low. Consequently, students who are graduating from college are often unable to take advantage of the many opportunities offered by science and technology. Cutting edge science and technology frequently use the methods learned in undergraduate courses, but up-to-date applications are not normally used as examples or for problems in undergraduate courses. There are many physics problems which contain information about the latest achievements in science and technology. But typically, the level of these problems is too advanced for undergraduates. We created physics problems for undergraduate science and engineering students, which are based on the latest achievements in science and technology. These problems have been successfully used in our courses at the Polytechnic University in New York. We believe that university faculty may suggest such problems in order to provide information about the frontiers of science and technological, demonstrate the importance of undergraduate physics in solving contemporary problems and raise the interest of talented students in science. From the other side, our approach may be considered an indirect way for advertising advanced technologies, which undergraduate students and, even more important, future college graduates could use in their working lives.

ACCOUNTING AS BRANCH OF KNOWLEDGE: SCIENCE, TECHNOLOGY AND PRACTICE

2015-01-01

The aim of this study was to characterize the accounting as branch of knowledge in three different fields: science, technology and practice. Through theoretical essay, we was argued that, although distinct, these fields interact, in that, as epistemology that justified the analysis here undertaken, the practical activities may be technology subject matter and that to be effective if based on one or more sciences. The difference between science and technology is given by the nature of knowledg...

Science and technology disclosure is an integral part of our scientific work as researches; it is an induction process for children, young people and teachers of primary and secondary schools in the state of Queretaro. Education must be offered in a clear and objective way, it allows to the students apply the acquired knowledge to understand the world and improve his quality of life. Nowadays, the Centro de Investigacion en Ciencia Aplicada y Tecnologia Avanzada of the Instituto Politecnico Nacional Unidad Queretaro (CICATA-IPN Queretaro) together with the Consejo de Ciencia y Tecnologia del Estado de Queretaro (CONCYTEQ) have implemented the "Science and Technology for Children" program (Ciencia y Tecnologia para Ninos - CTN), it allows to the educative sector obtain information through the CONCYTEQ web page. The fist stage of the program was the development of two subjects: the brochure titled "Petroleum, Nonrenewable Natural Resource that Moves the World" and the manual "Experiments of Physics". At the moment we are working with the second stage of the program, it is about the energy generation using renewable sources such as: geothermal, aeolian, solar and biomass. The CTN program allows to students and teachers to create conscience about the importance of the development of the science of technology in our country.

The TeXas Earth and Space Science (TXESS) Revolution, a professional development program for 8th- thru 12th-grade Earth Science teachers, presented a one-week Petroleum Science and Technology Institute at The University of Texas at Austin campus. The summer program was a joint effort between the Jackson School of Geosciences and the Department of Petroleum and Geosystems Engineering. The goal of the institute was to focus on the STEM components involved in the petroleum industry and to introduce teachers to the larger energy resources theme. The institute kicked off with a welcoming event and tour of a green, energy-efficient home (LEED Platinum certified) owned by one of the petroleum engineering faculty. Tours of the home included an introduction to rainwater harvesting, solar energy, sustainable building materials and other topics on energy efficiency. Classroom topics included drilling technology (including a simulator lab and an overview of the history of the technology), energy use and petroleum geology, well-logging technology and interpretation, reservoir engineering and volumetrics (including numerous labs combining chemistry and physics), risk assessment and economics, carbon capture and storage (CO2 sequestration technology) and hydraulic fracturing. A mid-week field trip included visiting the Ocean Star offshore platform in Galveston, the Weiss Energy Hall at the Houston Museum of Science and Schlumberger (to view 3-D visualization technology) in Houston. Teachers remarked that they really appreciated the focused nature of the institute and especially found the increased use of mathematics both a tool for professional growth, as well as a challenge for them to use more math in their science classes. STEM integration was an important feature of the summer institute, and teachers found the integration of science (earth sciences, geophysics), technology, engineering (petroleum, chemical and reservoir) and mathematics particularly valuable.

In this paper, a knowledge domain visualization approach is applied to the nuclear science and technology fields. A so-called concept density map based on the abstracts of the papers presented at the ICONE 14 is constructed. The concept map provides an overview of the nuclear science and technology fields by visualizing the associations between their main concepts. To analyze recent developments the concept map is compared with a concept map based on abstracts of earlier ICONE meetings. The analysis presented in the paper provides insight into the structure of the nuclear science and technology fields and into the most significant developments carried out during the last few years.

Democratizing science and technology education: Perspectives from the philosophy of education

Science.gov (United States)

Pierce, Clayton Todd

This study examines conceptualizations of science and technology and their relation to ideas of democratic education in the history of philosophy of education. My genealogical analysis begins by tracing the anti-democratic emergence of ideas and values of science and technology that have evolved through ancient and modern periods within the philosophy of education and continue to shape the ways science and technology are understood and treated in educational settings. From my critical engagement with Plato's Republic and Rousseau's Emile, I argue that anti-democratic structures and values have been embedded in philosophy of education through Plato's educational theory of techne and Rousseau's pedagogical theory that involves science and technology as important educational force. Following this theme, I analyze the work of John Dewey and Herbert Marcuse and their shared project for democratizing science and technology through education. Through a critical comparison of both theorists' models, I suggest that each provides positive legacies for philosophy of education to draw upon in rethinking the intersection of science, technology, and education: a strong model for understanding public problems associated with a highly technological and scientific society and a reconstructive framework for values and sensibilities that demands a new value relationship to be developed between humans and science and technology. Finally, I situate my critique and assessment of this history in the philosophy of education within the current science and technology education reform movement in the United States. I claim that the official models of science and technological literacy and inquiry, as constructed by the National Academy of Sciences and a host of governmental policies, shape science and technology education with a decidedly neo-liberal focus and purpose. In response to this anti-democratic movement I offer an alternative position that utilizes a counter-epistemology to the

The Program on Environmental Science and Technology developed at the Chemical and Environmental Technology Center comprehends environmental chemistry (water, soil and atmospheric chemistry), clean technologies (desulfurization of diesel and oil, biodegradable polymers and structural modification of polymers, recycling, pyrolysis of dangerous chemicals by molten salt technology), nanotechnology (magnetic nanoparticles, dendrimers, nano biomarkers, catalysts) and chemical characterization of nuclear fuel and nuclear fuel cycle waste (chemical and isotopic characterization). The Chemical and Environmental Technology Center was established in 1995, as an evolution of the former Department of Chemistry Engineering (1970). The program on environment science and technology was structured as consequence of the continuous growth of environmental activities on areas related to nuclear programs of IPEN. Moreover, it was an answer to the society concerning the climate changes and biodiversity preservation. All activities of research and development, services, supervision of graduate and under graduated students and courses performance at the center were related to the development, improvement and establishment of new technologies. The highlights of this period (2011 - 2013) were: - Development and use of modern analytical technology for the characterization of persistent pollutants and endocrine disrupters (metals, PAHA’s, PCBs, Pesticides, hormones, surfactants, plasticizer and human pharmaceuticals) in order to evaluate water quality and/or sediments; - Atmospheric chemistry and greenhouse gases: Evaluating an estimation of surface trace gas fluxes from aircraft measurements above the Amazon; - Cooperation with SABESP (Water and Sewage Company) and CETESB (State Environment Agency) in program for the development of public policies; - Studies and development in biodegradable polymers, polyolefins and advanced methods for polymer and rubber recycling and re-use; - Studies

On the Teaching of Science, Technology and International Affairs.

Science.gov (United States)

Weiss, Charles

2012-03-01

Despite the ubiquity and critical importance of science and technology in international affairs, their role receives insufficient attention in traditional international relations curricula. There is little literature on how the relations between science, technology, economics, politics, law and culture should be taught in an international context. Since it is impossible even for scientists to master all the branches of natural science and engineering that affect public policy, the learning goals of students whose primary training is in the social sciences should be to get some grounding in the natural sciences or engineering, to master basic policy skills, to understand the basic concepts that link science and technology to their broader context, and to gain a respect for the scientific and technological dimensions of the broader issues they are addressing. They also need to cultivate a fearless determination to master what they need to know in order to address policy issues, an open-minded but skeptical attitude towards the views of dueling experts, regardless of whether they agree with their politics, and (for American students) a world-view that goes beyond a strictly U.S. perspective on international events. The Georgetown University program in Science, Technology and International Affairs (STIA) is a unique, multi-disciplinary undergraduate liberal arts program that embodies this approach and could be an example that other institutions of higher learning might adapt to their own requirements.

2014-08-01

The life sciences field is entering an era of big data with the breakthroughs of science and technology. More and more big data-related projects and activities are being performed in the world. Life sciences data generated by new technologies are continuing to grow in not only size but also variety and complexity, with great speed. To ensure that big data has a major influence in the life sciences, comprehensive data analysis across multiple data sources and even across disciplines is indispensable. The increasing volume of data and the heterogeneous, complex varieties of data are two principal issues mainly discussed in life science informatics. The ever-evolving next-generation Web, characterized as the Semantic Web, is an extension of the current Web, aiming to provide information for not only humans but also computers to semantically process large-scale data. The paper presents a survey of big data in life sciences, big data related projects and Semantic Web technologies. The paper introduces the main Semantic Web technologies and their current situation, and provides a detailed analysis of how Semantic Web technologies address the heterogeneous variety of life sciences big data. The paper helps to understand the role of Semantic Web technologies in the big data era and how they provide a promising solution for the big data in life sciences.

In this paper, we introduce the themes addressed and the approaches used in this special issue. We start by briefly discussing the state of the art in research and policy making related to science, technology and ageing. We argue that an important gap characterizes this state of the art: current...... approaches do not consider material practice and materiality to be an inherent part of later life as constituted in contemporary societies. Science and Technology Studies (STS) provide both the theories and methods to address this gap, and thus deploy a theoretical and empirical understanding of science......, technology and ageing that captures how later life co-evolves with the practices of technology use and design. We briefly discuss how the articles in the collection each contribute to such an understanding across various locations. We conclude that, together, the contributions specify a perspective...

In the aftermath of the Cold War, the United States has begun addressing the environmental consequences of five decades of nuclear weapons production. In November 1989, DOE established the Office of Environmental Restoration and Waste Management (EM) as the central authority for cleaning up the DOE weapons complex legacy of pollution, for preventing further environmental contamination, and for instituting responsible environmental management. While performing its tasks, EM found that many aspects of its large and complex mission could not be achieved using existing science and technology or without incurring unreasonable costs, risks, or schedule impacts. Consequently, a process was developed to solicit needs from around the DOE complex and focus the science and technology resources of EM-50, the National Laboratories, private industry, and colleges and universities on those needs. This document describes those needs that the Hanford Site has identified as requiring additional science or technology to complete.

Using Technology to Facilitate Differentiated High School Science Instruction

Science.gov (United States)

Maeng, Jennifer L.

2017-10-01

This qualitative investigation explored the beliefs and practices of one secondary science teacher, Diane, who differentiated instruction and studied how technology facilitated her differentiation. Diane was selected based on the results of a previous study, in which data indicated that Diane understood how to design and implement proactively planned, flexible, engaging instructional activities in response to students' learning needs better than the other study participants. Data for the present study included 3 h of semi-structured interview responses, 37.5 h of observations of science instruction, and other artifacts such as instructional materials. This variety of data allowed for triangulation of the evidence. Data were analyzed using a constant comparative approach. Results indicated that technology played an integral role in Diane's planning and implementation of differentiated science lessons. The technology-enhanced differentiated lessons employed by Diane typically attended to students' different learning profiles or interest through modification of process or product. This study provides practical strategies for science teachers beginning to differentiate instruction, and recommendations for science teacher educators and school and district administrators. Future research should explore student outcomes, supports for effective formative assessment, and technology-enhanced readiness differentiation among secondary science teachers.

Information technology and global change science

Energy Technology Data Exchange (ETDEWEB)

Baxter, F.P.

1990-01-01

The goal of this paper is to identify and briefly describe major existing and near term information technologies that cold have a positive impact on the topics being discussed at this conference by helping to manage the data of global change science and helping global change scientists conduct their research. Desktop computer systems have changed dramatically during the past seven years. Faster data processing can be expected in the future through full development of traditional serial computer architectures. Some other proven information technologies may be currently underutilized by global change scientists. Relational database management systems and good organization of data through the use of thoughtful database design would enable the scientific community to better share and maintain quality research data. Custodians of the data should use rigorous data administration to ensure integrity and long term value of the data resource. Still other emerging information technologies that involve the use of artificial intelligence, parallel computer architectures, and new sensors for data collection will be in relatively common use in the near term and should become part of the global science community's technical toolkit. Consideration should also be given to the establishment of Information Analysis Centers to facilitate effective organization and management of interdisciplinary data and the prototype testing and use of advanced information technology to facilitate rapid and cost-effective integration of these tools into global change science. 8 refs.

Science and technology planning in LDCs: major policy issues

Energy Technology Data Exchange (ETDEWEB)

Wionczek, M S

1979-05-01

Science in the less-developed countries (LDCs) should be underplanned rather than overplanned. Furthermore, the planning should be directed to the outer fringes of the scientific endeavor and to its infrastructure and not to the substance of scientific research itself. Planning of applied research and technological development in the LDC is another story. It cannot be done without entering into the substantive problems of applied research and technological development. Attempts to set the broad overall national targets for science and technology (S and T) expenditures -in terms of the proportion of the (GNP) or the per capita income- which do not consider the science and technology system's financial and human resources absorption capacity, are useless. 8 references.

Technological changes, new materials, and their impact on the demand for minerals

International Nuclear Information System (INIS)

Rogich, D.G.

1991-01-01

Almost all mineral commodities compete in an international market, and changing technologies and preferences can impact this materials market to either increase or decrease the demand for specific minerals. This paper presents information on the changes we are seeing in materials usage in the United States, some specific examples of market penetration and methods to evaluate this, and some preliminary data on worldwide trends. Traditionally, evaluating the viability of a mineral venture involves the estimation of anticipated costs, production rates, mine life, and discount rates. These estimated costs are then compared with current and expected future prices to see if the necessary return on investment is likely to be generated. Additionally, an examination of the current, and expected future competition in the market is certainly of interest since an assessment of where the operation's costs fall in relation to the total world supply determines how far demand/prices can fall before stronger operations can supply the whole market. Feedstock price has been the traditional measure in the minerals community, and most producers think of themselves as suppliers of particular commodities in competition with other similar suppliers. However, this approach must be altered when we seek to evaluate how individual commodities compete in a market where substitution is expanding

Critical materialism: science, technology, and environmental sustainability.

Science.gov (United States)

York, Richard; Clark, Brett

2010-01-01

There are widely divergent views on how science and technology are connected to environmental problems. A view commonly held among natural scientists and policy makers is that environmental problems are primarily technical problems that can be solved via the development and implementation of technological innovations. This technologically optimistic view tends to ignore power relationships in society and the political-economic order that drives environmental degradation. An opposed view, common among postmodernist and poststructuralist scholars, is that the emergence of the scientific worldview is one of the fundamental causes of human oppression. This postmodernist view rejects scientific epistemology and often is associated with an anti-realist stance, which ultimately serves to deny the reality of environmental problems, thus (unintentionally) abetting right-wing efforts to scuttle environmental protection. We argue that both the technologically optimistic and the postmodernist views are misguided, and both undermine our ability to address environmental crises. We advocate the adoption of a critical materialist stance, which recognizes the importance of natural science for helping us to understand the world while also recognizing the social embeddedness of the scientific establishment and the need to challenge the manipulation of science by the elite.

Nuclear science and technology education and training in Indonesia

International Nuclear Information System (INIS)

Karsono

2007-01-01

Deployment of nuclear technology requires adequate nuclear infrastructure which includes governmental infrastructure, science and technology infrastructure, education and training infrastructure, and industrial infrastructure. Governmental infrastructure in nuclear, i.e. BATAN (the National Nuclear Energy Agency) and BAPETEN (the Nuclear Energy Control Agency), need adequate number of qualified manpower with general and specific knowledge of nuclear. Science and technology infrastructure is mainly contained in the R and D institutes, education and training centers, scientific academies and professional associations, and national industry. The effectiveness of this infrastructure mainly depends on the quality of the manpower, in addition to the funding and available facilities. Development of human resource needed for research, development, and utilization of nuclear technology in the country needs special attention. Since the national industry is still in its infant stage, the strategy for HRD (human resource development) in the nuclear field addresses the needs of the following: BATAN for its research and development, promotion, and training; BAPETEN for its regulatory functions and training; users of nuclear technology in industry, medicine, agriculture, research, and other areas; radiation safety officers in organizations or institutions licensed to use radioactive materials; the education sector, especially lecturers and teachers, in tertiary and secondary education. Nuclear science and technology is a multidisciplinary and a highly specialized subject. It includes areas such as nuclear and reactor physics, thermal hydraulics, chemistry, material science, radiation protection, nuclear safety, health science, and radioactive waste management. Therefore, a broad nuclear education is absolutely essential to master the wide areas of science and technology used in the nuclear domain. The universities and other institutions of higher education are the only

Identification of cave minerals by Raman spectroscopy: new technology for non-destructive analysis

Directory of Open Access Journals (Sweden)

White William B.

2006-07-01

Full Text Available The usual tools are X-ray powder diffraction, the optical microscope, and the scanning electron microscope. X-ray diffraction gives a definitive fingerprint by which the mineral can be identified by comparison with a catalog of reference patterns. However, samples must be ground to powder and unstable hydrated minerals may decompose before analysis is complete. Raman spectroscopy also provides a fingerprint useful for mineral identification but with the additional advantage that some a-priori interpretation of the spectra is possible (distinguishing carbonates from sulfates, for example. Because excitation of the spectra is by means of a laser beam, it is possible to measure the spectra of samples in sealed glass containers, thus preserving unstable samples. Because laser beams can be focused, spectra can be obtained from individual grains. New technology has reduced the size of the instrument and also the sensitivity of the optical system to vibration and transport so that a portable instrument has become possible. The sampling probe is linked to the spectrometer by optical fibers so that large specimens can be examined without damage. Comparative spectra of common cave minerals demonstrate the value of Raman spectra as an identification technique.

Vázquez-Alonso, Ángel; García-Carmona, Antonio; Manassero-Mas, María Antonia; Bennàssar-Roig, Antoni

2013-05-01

This study analyzes the beliefs about science-technology-society, and other Nature of Science (NOS) themes, of a large sample (613) of Spanish pre- and in-service secondary education teachers through their responses to 30 items of the Questionnaire of Opinions on Science, Technology and Society. The data were processed by means of a multiple response model to generate the belief indices used as the bases for subsequent quantitative and qualitative analyses. Other studies have reported a negative profile of teachers' understanding in this area, but the diagnosis emerging from the present work is more complex. There was a mix of appropriate beliefs coexisting with others that are inappropriate on the topics analyzed. The overall assessment, however, is negative since clearly teachers need to have a better understanding of these questions. There were scant differences between the pre- and in-service teachers, and hence no decisive evidence that the practice of teaching contributes to improving the in-service teachers' understanding. These results suggest there is an urgent need to bring the initial and continuing education of science teachers up to date to improve their understanding of these topics of science curricula, and thus improve the teaching of science.

Colon, Frances

President Obama's announcement of U. S. policy change toward Cuba and increased freedom of interaction with the Cuban people opens unprecedented and long-awaited opportunities for the scientific and engineering communities in the U. S. and in Cuba to establish and expand collaborative efforts that will greatly advance U.S. and Cuba science and technology agendas. New rules for export of donated-only items for scientific use will bring researchers closer to the level of their professional peers around the world. Increasing Cubans' access to information will result in greater interactions between scientific communities and enable the sharing of ideas and discoveries that can fuel entrepreneurship on the island. The scientific community has expressed an extraordinary level of interest in the wide range of scientific opportunities that the new policy presents, in collaborating with their Cuban counterparts, and in supporting the development of scientific capacity in Cuba. In response to numerous expressions of interest and inquiries from the scientific community, the Office of the Science and Technology Adviser to the Secretary of State (STAS) has engaged in public outreach to inform the U.S. science and technology community of the implications of the new policy for collaborative research, emerging scientific opportunities, and the standing limitations for engagement with the people of Cuba.

The effect of technology on student science achievement

Science.gov (United States)

Hilton, June Kraft

2003-10-01

Prior research indicates that technology has had little effect on raising student achievement. Little empirical research exists, however, studying the effects of technology as a tool to improve student achievement through development of higher order thinking skills. Also, prior studies have not focused on the manner in which technology is being used in the classroom and at home to enhance teaching and learning. Empirical data from a secondary school representative of those in California were analyzed to determine the effects of technology on student science achievement. The quantitative analysis methods for the school data study included a multiple linear path analysis, using final course grade as the ultimate exogenous variable. In addition, empirical data from a nationwide survey on how Americans use the Internet were disaggregated by age and analyzed to determine the relationships between computer and Internet experience and (a) Internet use at home for school assignments and (b) more general computer use at home for school assignments for school age children. Analysis of data collected from the a "A Nation Online" Survey conducted by the United States Census Bureau assessed these relationships via correlations and cross-tabulations. Finally, results from these data analyses were assessed in conjunction with systemic reform efforts from 12 states designed to address improvements in science and mathematics education in light of the Third International Mathematics and Science Survey (TIMSS). Examination of the technology efforts in those states provided a more nuanced understanding of the impact technology has on student achievement. Key findings included evidence that technology training for teachers increased their use of the computer for instruction but students' final science course grade did not improve; school age children across the country did not use the computer at home for such higher-order cognitive activities as graphics and design or spreadsheets

Roadmapping or development of future investments in environmental science and technology

This paper will summarize efforts in roadmapping SCFA technical targets, which could be used for selection of future projects. The timely lessons learned and insights will be valuable to other programs desiring to roadmap large amounts of workscope, but unsure how to successfully complete it, by adequately defining a strategy to develop alternatives and core technologies to ensure needed environmental technologies are available and allow delivery of viable alternatives. In early FY02, Los Alamos National Laboratory's Environmental Science and Waste Technology Program Office was working jointly with Idaho National Environmental Engineering Laboratory to define and develop science and technology mini-roadmaps. We were defining and developing these mini-roadmaps to provide direction and guidance for DOE's Environmental Management's (DOE-EM) Subsurface Contaminants Focus Area (SCFA) in their development of target technologies. DOE EM's Strategic Plan for Science and Technology provides guidance for meeting science and technology needs with a view of the desired future and the long-term strategy to attain it. Program and technology mini-roadmapping were to be used to establish priorities, set program and project direction, and identify the high-priority science and technology need areas according to this document. In the past, EM science and technology needs collection is achieved through the DOE Site Technology Coordination Groups (STCG) across the complex. A future system for needs collection has not been defined. However, there is a need for gap analyses and a technical approach for the prioritization of these needs for DOE-EM to be strategic and successful in their technology research, development, demonstration, and deployments. To define the R&D projects needed to solve particular problems and select the project with the largest potential payoff will require analysis for project selection. Mini-roadmaps could be used for setting goals and

Public engagement with science and technology is now widely used in science policy and communication. Touted as a means of enhancing democratic discussion of science and technology, analysis of public engagement with science and technology has shown that it is often weakly tied to scientific governance. In this article, we suggest that the notion of capacity building might be a way of reframing the democratic potential of public engagement with science and technology activities. Drawing on literatures from public policy and administration, we outline how public engagement with science and technology might build citizen capacity, before using the notion of capacity building to develop five principles for the design of public engagement with science and technology. We demonstrate the use of these principles through a discussion of the development and realization of the pilot for a large-scale public engagement with science and technology activity, the Futurescape City Tours, which was carried out in Arizona in 2012.

A case for Sandia investment in complex adaptive systems science and technology.

Energy Technology Data Exchange (ETDEWEB)

Colbaugh, Richard; Tsao, Jeffrey Yeenien; Johnson, Curtis Martin; Backus, George A.; Brown, Theresa Jean; Jones, Katherine A.

2012-05-01

This white paper makes a case for Sandia National Laboratories investments in complex adaptive systems science and technology (S&T) -- investments that could enable higher-value-added and more-robustly-engineered solutions to challenges of importance to Sandia's national security mission and to the nation. Complex adaptive systems are ubiquitous in Sandia's national security mission areas. We often ignore the adaptive complexity of these systems by narrowing our 'aperture of concern' to systems or subsystems with a limited range of function exposed to a limited range of environments over limited periods of time. But by widening our aperture of concern we could increase our impact considerably. To do so, the science and technology of complex adaptive systems must mature considerably. Despite an explosion of interest outside of Sandia, however, that science and technology is still in its youth. What has been missing is contact with real (rather than model) systems and real domain-area detail. With its center-of-gravity as an engineering laboratory, Sandia's has made considerable progress applying existing science and technology to real complex adaptive systems. It has focused much less, however, on advancing the science and technology itself. But its close contact with real systems and real domain-area detail represents a powerful strength with which to help complex adaptive systems science and technology mature. Sandia is thus both a prime beneficiary of, as well as potentially a prime contributor to, complex adaptive systems science and technology. Building a productive program in complex adaptive systems science and technology at Sandia will not be trivial, but a credible path can be envisioned: in the short run, continue to apply existing science and technology to real domain-area complex adaptive systems; in the medium run, jump-start the creation of new science and technology capability through Sandia's Laboratory Directed Research

2009-10-01

Cognitive studies of science and technology have had a long history of largely independent research projects that have appeared in multiple outlets, but rarely together. The emergence of a new International Society for Psychology of Science and Technology suggests that this is a good time to put some of the latest work in this area into topiCS in a way that will both acquaint readers with the cutting edge in this domain and also give them a hint of its history. One core theme includes how scientists, inventors, and engineers represent and solve problems; another, related theme is the extent to which they distribute and share cognition. Methodologies include fine-grained studies of historical records, protocols of working scientists, observations and comparisons of engineering science laboratories, and computational simulations designed both to serve as research tools and also to improve scientific problem-solving. The series of articles will conclude with the Associate Editor's suggestions for future research. Copyright © 2009 Cognitive Science Society, Inc.

Directory of Open Access Journals (Sweden)

Teresa Castelao-Lawless

2001-01-01

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

The mineral and environmental assessments of domestic deposits are used by planners and decisionmakers to improve the stewardship of public lands and public resources. Assessments of undiscovered mineral deposits on a global scale reveal the potential availability of minerals to the United States and other countries that manufacture goods imported to the United States. These resources are of fundamental relevance to national and international economic and security policy in our globalized world economy. Performing mineral and environmental assessments requires that predictions be made of the likelihood of undiscovered deposits. The predictions are based on geologic and geoenvironmental models that are constructed for the diverse types of mineral deposits from detailed descriptions of actual deposits and detailed understanding of the processes that formed them. Over the past three decades the understanding of ore-forming processes has benefited greatly from the integration of laboratory-based geochemical tools with field observations and other data sources. Under the aegis of the Evolution of Ore Deposits and Technology Transfer Project (referred to hereinafter as the Project), a 5-year effort that terminated in 2008, the Mineral Resources Program provided state-of-the-art analytical capabilities to support applications of several related geochemical tools to ore-deposit-related studies. The analytical capabilities and scientific approaches developed within the Project have wide applicability within Earth-system science. For this reason the Project Laboratories represent a valuable catalyst for interdisciplinary collaborations of the type that should be formed in the coming years for the United States to meet

Science and technology in the global Cold War

CERN Document Server

Krige, John

2014-01-01

The Cold War period saw a dramatic expansion of state-funded science and technology research. Government and military patronage shaped Cold War technoscientific practices, imposing methods that were project oriented, team based, and subject to national-security restrictions. These changes affected not just the arms race and the space race but also research in agriculture, biomedicine, computer science, ecology, meteorology, and other fields. This volume examines science and technology in the context of the Cold War, considering whether the new institutions and institutional arrangements that emerged globally constrained technoscientific inquiry or offered greater opportunities for it. The contributors find that whatever the particular science, and whatever the political system in which that science was operating, the knowledge that was produced bore some relation to the goals of the nation-state. These goals varied from nation to nation; weapons research was emphasized in the United States and the Soviet Unio...

Understanding Science and Technology Interactions Through Ocean Science Exploration: A Summer Course for Science Teachers

Baldauf, J.; Denton, J.

2003-12-01

In order to replenish the national supply of science and mathematics educators, the National Science Foundation has supported the formation of the Center for Applications of Information Technology in the Teaching and Learning of Science (ITS) at Texas A&M University. The center staff and affiliated faculty work to change in fundamental ways the culture and relationships among scientists, educational researchers, and teachers. ITS is a partnership among the colleges of education, science, geosciences, agriculture and life science at Texas A&M University. Participants (teachers and graduate students) investigate how science is done and how science is taught and learned; how that learning is assessed, and how scholarly networks among all engaged in this work can be encouraged. While the center can offer graduate degrees most students apply as non-degree seekers. ITS participants are schooled on classroom technology applications, experience working on project teams, and access very current research work being conducted by scientists. ITS offers a certificate program consisting of two summer sessions over two years that results in 12 hours of graduate credit that can be applied to a degree. Interdisciplinary project teams spend three intense weeks connecting current research to classroom practices. During the past summer with the beginning of the two-year sequence, a course was implemented that introduced secondary teachers to Ocean Drilling Program (ODP) contributions to major earth science themes, using core and logging data, engineering (technology) tools and processes. Information Technology classroom applications were enhanced through hands-on laboratory exercises, web resources and online databases. The course was structured around the following objectives. 1. Distinguish the purpose and goals of the Ocean Drilling Program from the Integrated Ocean Drilling Program and describe the comparable science themes (ocean circulation, marine sedimentation, climate history

Boundaries and audiences of national histories of science: insights from the history of science and technology of the Netherlands.

Science.gov (United States)

Homburg, Ernst

2008-01-01

The present paper traces the evolution of writing national-oriented histories of science and technology of the Netherlands. Several episodes are distinguished. A first wave of national histories of science and technology was written during the first decades of the 19th century. These histories had a wide scope, which included science, technology, the humanities and the arts. A second wave, which lasted from about 1865 to 1900, was strongly connected to the rise of the scientific professions. Its focus was on the sciences perse, and on the Dutch "Golden Age" of the 17th century. A third wave occurred during and shortly after the Second World War. Its focus was mainly on the "Second Golden Age" of Dutch science (1870-1910), and its major audience were young boys that were to be recruited to the sciences. The second part of the paper discusses the growing influence of "contextualization" in both the history of science and the history of technology from about 1975 onwards. As a result, local factors often received more attention in historical studies of science and technology than national influences. In 1985, Klaas van Berkel undertook a bold attempt to write a new synthesis of the history of Dutch science, but his approach was too strongly influenced by the three previous waves of national histories. From 1989 to 2003 two projects on the national history of technology resulted in 13 volumes on Dutch technology between 1800 and 1970. New research was initiated, and the issue of "national styles" in the development of technology received ample attention. In his conclusions the author points to lessons to be learned from economic history and the history of art, and he concludes with a plea for more historiographical discussion in the history of science and technology.

Plasma Science Committee (PLSC) and study on new opportunities in plasma science and technology

International Nuclear Information System (INIS)

1992-01-01

The Plasma Science Committee (PLSC) of the National Research Council (NRC) is charged with monitoring the health of the field of plasma science in the United States. Accordingly, the Committee identifies and examines both broad and specific issues affecting the field. Regular meetings, teleconferences, briefings from agencies and the scientific community, the formation of study panels to prepare reports, and special symposia are among the mechanisms used by the PLSC to meet its charge. This progress report presents a review of PLSC activities from July 15, 1991 to May 31, 1992. The details of prior activities are discussed in earlier reports. This report also includes the status of activities associated with the PLSC study on opportunities in plasma science and technology. During the above period, the PLSC has continued to track and participate in, when requested, discussions on the health of the field. Much of the perspective of the PLSC has been presented in the recently-published report Research Briefing on Contemporary Problems in Plasma Science. That report has served as the basis for briefings to representatives of the federal government as well as the community-at-large. In keeping with its charge to identify and highlight specific areas for scientific and technological opportunities, the PLSC completed publication of the report Plasma Processing of Materials: Scientific and Technological Opportunities and launched a study on new opportunities in plasma science and technology

Nature of Technology: Implications for design, development, and enactment of technological tools in school science classrooms

Science.gov (United States)

Waight, Noemi; Abd-El-Khalick, Fouad

2012-12-01

This position paper provides a theory-based explanation informed by philosophy of technology (PoT) of the recurrent documented patterns often associated with attempts to enact technology-supported, inquiry-based approaches in precollege science classrooms. Understandings derived from the history of technological development in other domains (e.g. medicine, transportation, and warfare) reveal numerous parallels that help to explain these recurrent patterns. Historical analyses of major technologies reveal a conglomerate of factors that interact to produce benefits, as well as intended and unintended consequences. On a macro-scale, PoT facilitates understandings of how technologies interact and are impacted by individuals, society, institutions, economy, politics, and culture. At the micro-level, and most relevant to science education, PoT engages the inherent nature of technology along a number of key dimensions: role of culture and values, notions of technological progression, technology as part of systems, technological diffusion, technology as a fix, and the notions of expertise. Overall, the present analysis has implications for the design, development, implementation, and adoption of technological tools for use in precollege science education, and highlights the role of technology as both artifact and process.

Whereas in our country's scientific and technological development are essentially in the hands of the State, conducting scientific outreach massive level, involve a degree of commitment by the state led to that effect. Responding to this premise, in 2012, took place in Cordoba some outdoors communication actions. This paper describes the main characteristics of them, specifying those aspects related to the spread of national nuclear activities within that framework. From a focus on science popularization and under the names of 'Scientific and Technological Cordoba Tourism' and 'Science and Technology in the popular events of Cordoba', dissemination events were held in places accessible to the public: beaches, rivers and pedestrian areas of the main cities of the province. It was organized by the Direction of Disclosure and Science Education, Ministry of Science and Technology of Cordoba, which called for researchers from participating institutions, among whom were those related to national nuclear activities. Simple experiments were presented, video projections, street and dissertations astronomical observations with discussion on various topics. The objective was to capitalize on the potential attractiveness of some physical and chemical phenomena curious, to summon people who were enjoying their free time. Those responsible for the activities were researchers, in several cases with doctoral level and calling for the release, as well as professionals in educational sciences. Some of the activities involved in the group's visit transcendent opportunity celebrations in the interior provincial, or events with massive public support. In the case of atomic energy the approach used was based on natural radioactivity and radiation. From the point of view of the results obtained, it can be said that the popularization of science and technology has begun to present itself as an alternative learning of citizenship, which has been well received

The first is the Promotion of the realization of scientific research school works to present in science and technology fairs. The public exhibitions fairs consist of projects conducted by students from all levels of the education system. To do this, students have the guidance of Advisory Teachers, researchers and technologists of the local scientific community, which involves training them for a period of approximately six months. During this year the courses were conducted in 37 cities in the interior province, which are the sites of Regional Headquarters, which included the promotion of the realization of school scientific research on the peaceful applications of nuclear technology and / or national nuclear activities. During the meetings, made presentations basing pedagogical and didactic aspects to coordination between teaching of conceptual content and activities practical introduction to nuclear scientific methodology. As a result of this initiative, between the months of June and September was reached more than 3,000 teachers, using the infrastructure of the Ministry of Science and Technology and Internet. As a result, a dozen schools have begun to seek assistance to develop projects related to nuclear power. Other activities under the name of Scientific School Research Incursion through Experiences with Natural Radiation, consisted of the design and realization of simple laboratory experiences in laboratory's schools. The objective was to strengthen the curriculum and promote critical thinking about the risks and benefits of nuclear technologies in relation to exposure to ionizing radiation involving them. As a result it has been observed that these activities contribute to a progressive scientific and technological literacy of students, who build original knowledge for themselves and develop

Marine Technology for Teachers and Students: A Multi-modal Approach to Integrate Technology and Ocean Sciences Instruction

Science.gov (United States)

Gingras, A.; Knowlton, C. W.; Scowcroft, G. A.; Babb, I.; Coleman, D.; Morin, H.

2016-02-01

The Marine Technology for Teachers and Students (MaTTS) Project implements a year-long continuum of activities beginning with educators reading and reporting on peer-reviewed publications, followed by face-to-face, hands-on weekend workshops and virtual professional development activities. Teams of teacher and student leaders then participate in an intensive, residential Summer Institute (SI) that emphasizes hands-on building of marine related technologies and exposure to career pathways through direct interactions with ocean scientists and engineers. During the school year, teachers integrate ocean science technology and data into their classrooms and participate, along with colleagues and students from their schools, in science cafes and webinars. Student leaders transfer knowledge gained by engaging their district's middle school students in ocean science activities and technologies by serving as hosts for live broadcasts that connect classrooms with ocean scientists and engineers though the Inner Space Center, a national ocean science telecommunications hub. Communication technologies bridge formal and informal learning environments, allowing MaTTS participants to interact with their fellow cohort members, scientists, and engineers both during and outside of school. Evaluation results indicate that for teachers both the weekend workshops and SI were most effective in preparing them to integrate ocean science and technology in STEM curricula and increase their ocean science content knowledge and leadership characteristics. For students the SI and the middle school interactions supported gains in knowledge, awareness, leadership skills and interest in ocean sciences and technologies, and related STEM careers. In particular, the connections made by working directly with scientists have positively impacted both student and teacher leaders. This presentation will provide an overview of the MaTTS model and early evaluation results.

Teacher candidates in an online post-baccalaureate science methods course: Implications for teaching science inquiry with technology

Science.gov (United States)

Colon, Erica L.

Online learning is becoming more prevalent in today's education and is changing the way students learn and instructors teach. This study proposed using an informative case study design within a multilevel conceptual framework as teacher candidates were learning to teach and use science inquiry while in an online post-baccalaureate science methods course. The purposes were to (a) explore whether the teacher candidates had a thorough understanding of scientific inquiry and how to implement higher-order thinking skills, (b) examine whether or not the teacher candidates used a variety of computer-based instructional technologies when choosing instructional objectives, and (c) identify barriers that impede teacher candidates from using science inquiry or technology singly, or the ability to incorporate technology into learning science inquiry. The findings indicate that an online approach in preparing science teachers holds great potential for using innovative technology to teach science inquiry. First, the teacher candidates did incorporate essential features of classroom inquiry, however it was limited and varied in the type of inquiry used. Second, of the 86 lesson plans submitted by the teacher candidates, less than twelve percent of the learning objectives involved higher-order skills that promoted science inquiry. Third, results supported that when using technology in their lesson planning, participants had widely varying backgrounds in reference to their familiarity with technology. However, even though each participant used some form or another, the technology used was fairly low level. Finally, when discussing implementing inquiry-based science in the lesson plans, this study identified time as a reason that participants may not be pushing for more inquiry-based lessons. The researcher also identifies that school placements were a huge factor in the amount of inquiry-based skills coded in the lesson plans. The study concludes that online teacher preparation

The Brazilian investment in science and technology

Directory of Open Access Journals (Sweden)

Pinheiro-Machado R.

2001-01-01

Full Text Available An analysis of Brazilian federal expenditures in science and technology is presented is this study. The 1990-1999 data were compiled from records provided by two federal agencies (MCT and CNPq responsible for managing most of the national budget related to these activities. The results indicate that the federal investments in Brazilian science and technology stagnated during the last decade (US$ 2.32 billion in 1990, US$ 2.39 billion in 1996, and US$ 2.36 billion in 1999. In contrast, a great increase in private investments in research was acknowledged both by industry and by the government during the same period, from US$ 2.12 to US$ 4.64 billion. However, this investment did not result in an increase in invention patents granted to residents (492 in 1990 and only 232 in 1997 or in a reduction of patent costs. Despite this unfavorable scenario, the number of graduate programs in the country has increased two-fold in the last decade and the contribution of Brazilians to the database of the Institute for Scientific Information has increased 4.7-fold from 1990 (2,725 scientific publications to 2000 (12,686 scientific publications. Unstable federal resources for science, together with the poor returns of private resources in terms of developing new technologies, may jeopardize the future of Brazilian technological development.

Principal Leadership for Technology-enhanced Learning in Science

Science.gov (United States)

Gerard, Libby F.; Bowyer, Jane B.; Linn, Marcia C.

2008-02-01

Reforms such as technology-enhanced instruction require principal leadership. Yet, many principals report that they need help to guide implementation of science and technology reforms. We identify strategies for helping principals provide this leadership. A two-phase design is employed. In the first phase we elicit principals' varied ideas about the Technology-enhanced Learning in Science (TELS) curriculum materials being implemented by teachers in their schools, and in the second phase we engage principals in a leadership workshop designed based on the ideas they generated. Analysis uses an emergent coding scheme to categorize principals' ideas, and a knowledge integration framework to capture the development of these ideas. The analysis suggests that principals frame their thinking about the implementation of TELS in terms of: principal leadership, curriculum, educational policy, teacher learning, student outcomes and financial resources. They seek to improve their own knowledge to support this reform. The principals organize their ideas around individual school goals and current political issues. Principals prefer professional development activities that engage them in reviewing curricula and student work with other principals. Based on the analysis, this study offers guidelines for creating learning opportunities that enhance principals' leadership abilities in technology and science reform.

In order to realize Nigeria's aspiration to harness nuclear science and technology for socio-economic development of the society, the federal government of Nigeria charged the Nigeria Atomic Energy Commission (NAEC) with the responsibility of promotion and development of peaceful uses of nuclear energy in all its ramifications. In realization of this laudable objective, two University-based nuclear research centres at Ile-Ife (i.e. Centre for Energy Research and Development, CERD, Obafemi Awolowo University, Ile-Ife) and Zaria (i.e. Centre for Energy Research and Training, CERT, Ahmadu Bello University, Zaria) under the supervision of NAEC are already running R and D programmes in nuclear science and technology for over three decades. A third centre, also under the supervision of the Commission in Abuja namely the Nuclear Technology Centre (NTC) located within the Sheda Science and Technology Complex (SHESTCO) was established in 1991 and operates a Gamma Irradiation Faci lity (GIF). Furthermore, NAEC has instituted a number of programmes including a road map aimed at the introduction of nuclear option into the energy mix of the country with projected targets of 1000MWe and 4000MWe by 2017 and 2027 respectively. However, with the number of nuclear scientists, engineers and technicians required to run a 1000MWe power plant put at 1000, there is the need to grow human capital for the industry in Nigeria. In this presentation, exciting opportunities in nuclear science for young graduates are enumerated. The importance of nuclear science and technology education vis-a-vis national economy and security for improved living standard is discussed. Specific workforce issues and sample career choices in medical science, the environment and energy applications are highlighted. Progress made so far by NAEC in the area of human resources development and capacity building is presented.

Dana's Minerals and How to Study Them, Fourth Edition

Science.gov (United States)

Cribb, Warner

Anyone who spends time in a geology lab, natural science museum, or rock and mineral shop can see that nature provides us with an incredible variety of minerals. Countless introductory geology students get “turned on” to the science of geology by studying minerals. Despite the development of modern instruments that enable rapid and detailed mineral, chemical, and atomic structural analysis, the study of minerals by hand sample remains one of the most popular and economical pursuits of many professional geologists, students, and amateur mineral enthusiasts.Because individuals with varying backgrounds in physical science collect and study minerals, a considerable need exists for a reference text that can be effectively used by both professionals and amateurs. Edward Salisbury Dana published the first such text, Minerals and How to Study Them, over a century ago. The third and last edition of this book was published in 1948. In the 50 years since, considerable changes have occurred in the understanding of mineral chemistry, crystallography, and microscopy. As a result, Dana's third edition is somewhat out of date, and its presentation of material is somewhat antiquated for modern-day readers.

Pea, Roy D.; Gomez, Louis M.

1993-01-01

Project-enhanced science learning (PESL) provides students with opportunities for `cognitive apprenticeships' in authentic scientific inquiry using computers for data-collection and analysis. Student teams work on projects with teacher guidance to develop and apply their understanding of science concepts and skills. We are applying advanced computing and communications technologies to augment and transform PESL at-a-distance (beyond the boundaries of the individual school), which is limited today to asynchronous, text-only networking and unsuitable for collaborative science learning involving shared access to multimedia resources such as data, graphs, tables, pictures, and audio-video communication. Our work creates user technology (a Collaborative Science Workbench providing PESL design support and shared synchronous document views, program, and data access; a Science Learning Resource Directory for easy access to resources including two-way video links to collaborators, mentors, museum exhibits, media-rich resources such as scientific visualization graphics), and refine enabling technologies (audiovisual and shared-data telephony, networking) for this PESL niche. We characterize participation scenarios for using these resources and we discuss national networked access to science education expertise.

Information Extraction and Interpretation Analysis of Mineral Potential Targets Based on ETM+ Data and GIS technology: A Case Study of Copper and Gold Mineralization in Burma

Wenhui, Du; Yongqing, Chen; Nana, Guo; Yinglong, Hao; Pengfei, Zhao; Gongwen, Wang

2014-01-01

Mineralization-alteration and structure information extraction plays important roles in mineral resource prospecting and assessment using remote sensing data and the Geographical Information System (GIS) technology. Choosing copper and gold mines in Burma as example, the authors adopt band ratio, threshold segmentation and principal component analysis (PCA) to extract the hydroxyl alteration information using ETM+ remote sensing images. Digital elevation model (DEM) (30m spatial resolution) and ETM+ data was used to extract linear and circular faults that are associated with copper and gold mineralization. Combining geological data and the above information, the weights of evidence method and the C-A fractal model was used to integrate and identify the ore-forming favourable zones in this area. Research results show that the high grade potential targets are located with the known copper and gold deposits, and the integrated information can be used to the next exploration for the mineral resource decision-making

Mineral surface–organic matter interactions: basics and applications

International Nuclear Information System (INIS)

Valdrè, G; Moro, D; Ulian, G

2012-01-01

The ability to control the binding of biological and organic molecules to a crystal surface is central in several fields; for example, in biotechnology, catalysis, molecular microarrays, biosensors preparation and environmental sciences. The nano-morphology and nanostructure at the surface may have physico-chemical properties that are very different from those of the underlying mineral substrate. Recent developments in scanning probe microscopy (SPM) have widened the spectrum of possible investigations that can be performed at the nanometric level on the surface of minerals. They range from the study of physical properties such as surface potential, electric field topological determination, Brønsted–Lowry site distributions, to chemical and spectroscopic analysis in air, in liquid or in gaseous environments. After an introduction to SPM modes of operation and new SPM-based technological developments, we will present recent examples of applications in the study of interactions between organic matter and mineral surface and report on the advances in knowledge that have been made by the use of scanning probe microscopy.

Lybrand, R.; Zaharescu, D. G.; Gallery, R. E.

2017-12-01

The study of biogeochemical interfaces in soil requires powerful technologies that can enhance our ability to characterize mineral surfaces and interacting organisms at micro- to nanoscale resolutions. We aim to demonstrate potential applications of Helium Ion Microscopy in the earth and ecological sciences using, as an example, samples from a field experiment. We assessed samples deployed for one year along climatic and topographic gradients in two Critical Zone Observatories (CZOs): a desert to mixed conifer forest gradient (Catalina CZO) and a humid hardwood forest (Calhoun CZO). Sterile ground rock (basalt, quartz, and granite; 53-250 µm) was sealed into nylon mesh bags and buried in the surface soils of both CZOs. We employed helium ion and scanning electron microscopies to compare retrieved ground rock samples with sterile unreacted mineral controls in conjunction with the Environmental Molecular Sciences Laboratory at Pacific Northwest National Laboratory, USA. Our work showed early colonization of mesh bag materials by fungal and bacterial organisms from the field systems and identified morphological changes in mineral grains following exposure to the soil environment. Biological specimens observed on grain surfaces exhibited contrasting features depending on mineral type and ecosystem location, including fungal hyphae that varied in length, diameter, and surface morphologies. We also present imagery that provides evidence for incipient stages of mineral transformation at the fungal-mineral interface. Our findings demonstrate that helium ion microscopy can be successfully used to characterize grain features and biological agents of weathering in experimental field samples, representing a promising avenue for research in the biogeosciences. Future directions of this work will couple high resolution imaging with measures of aqueous and solid geochemistry, fungal morphological characterization, and microbial profiling to better understand mineral

Long-Term Stewardship Program Science and Technology Requirements

Energy Technology Data Exchange (ETDEWEB)

Joan McDonald

2002-09-01

Many of the United States’ hazardous and radioactively contaminated waste sites will not be sufficiently remediated to allow unrestricted land use because funding and technology limitations preclude cleanup to pristine conditions. This means that after cleanup is completed, the Department of Energy will have long-term stewardship responsibilities to monitor and safeguard more than 100 sites that still contain residual contamination. Long-term stewardship encompasses all physical and institutional controls, institutions, information, and other mechanisms required to protect human health and the environment from the hazards remaining. The Department of Energy Long-Term Stewardship National Program is in the early stages of development, so considerable planning is still required to identify all the specific roles and responsibilities, policies, and activities needed over the next few years to support the program’s mission. The Idaho National Engineering and Environmental Laboratory was tasked with leading the development of Science and Technology within the Long-Term Stewardship National Program. As part of that role, a task was undertaken to identify the existing science and technology related requirements, identify gaps and conflicts that exist, and make recommendations to the Department of Energy for future requirements related to science and technology requirements for long-term stewardship. This work is summarized in this document.

Science and technology perspective

International Nuclear Information System (INIS)

Knotek, M.L.

1993-01-01

This paper looks at the waste processing program for Hanford from the perspective of science and technology. The Hanford waste processing problem is but one phase of the total defense waste problem in the country, and a small part of the total waste disposal problem of the industrial base of the country. Basic research effort on this problem will address the specific problems encountered in the forms of this waste, but will also develop technology of use to the entire industrial base of the country, while at the same time trying to benefit from technology being developed in this industrial base. The Hanford waste represents a huge financial cost in terms of its present volume, if handled by the proposed methods of grouting and vitrification. To decrease this costs technology will have to come forward with new processes which result in the overall decrease in waste volume, if not the chemical tailoring of this volume to be more amenable to these disposal methods. There must be a tradeoff in overall costs, technology development costs, treatment and disposal costs. But in general, if separations can be carried to a more developed level, the volume reductions will give cost gains which will support the effort. As technology is developed, the flow charts set up for dealing with the different waste streams will be narrowed by decisions made at different points. Adequate scientific support for these decisions will result in the minimum costs in developing eventual waste processing streams

Nanosatellites for quantum science and technology

Bringing quantum science and technology to the space frontier offers exciting prospects for both fundamental physics and applications such as long-range secure communication and space-borne quantum probes for inertial sensing with enhanced accuracy and sensitivity. But despite important terrestrial pathfinding precursors on common microgravity platforms and promising proposals to exploit the significant advantages of space quantum missions, large-scale quantum test beds in space are yet to be realised due to the high costs and lead times of traditional 'Big Space' satellite development. But the 'small space' revolution, spearheaded by the rise of nanosatellites such as CubeSats, is an opportunity to greatly accelerate the progress of quantum space missions by providing easy and affordable access to space and encouraging agile development. We review space quantum science and technology, CubeSats and their rapidly developing capabilities and how they can be used to advance quantum satellite systems.

An increasing body of evidence relates the wide range of benefits mineral surfaces offer for the development of early living systems, including adsorption of small molecules from the aqueous phase, formation of monomeric subunits and their subsequent polymerization, and supramolecular assembly of biopolymers and other biomolecules. Each of these processes was likely a necessary stage in the emergence of life on Earth. Here, we compile evidence that templating and enhancement of prebiotically-relevant self-assembling systems by mineral surfaces offers a route to increased structural, functional, and/or chemical complexity. This increase in complexity could have been achieved by early living systems before the advent of evolvable systems and would not have required the generally energetically unfavorable formation of covalent bonds such as phosphodiester or peptide bonds. In this review we will focus on various case studies of prebiotically-relevant mineral-templated self-assembling systems, including supramolecular assemblies of peptides and nucleic acids, from nanoscience and surface science. These fields contain valuable information that is not yet fully being utilized by the origins of life and astrobiology research communities. Some of the self-assemblies that we present can promote the formation of new mineral surfaces, similar to biomineralization, which can then catalyze more essential prebiotic reactions; this could have resulted in a symbiotic feedback loop by which geology and primitive pre-living systems were closely linked to one another even before life’s origin. We hope that the ideas presented herein will seed some interesting discussions and new collaborations between nanoscience/surface science researchers and origins of life/astrobiology researchers.

This paper examines the images middle school students have of science and technology, the workplaces, and the relevant professions. It also describes the effect on these images caused by an instructional initiative, Investigation into Science and Technology (IST), designed to introduce students to science and technology in the real life. Students' images were delineated via questionnaires, drawing tasks, and interviews before and after their participation in the IST program. The sample consisted of 100 students from six classes (eighth or ninth grade) of three schools. We found that before the IST intervention students' images about the scientific or technological environments were superficial, unreal, and even incorrect. Their impressions of the characteristics of scientists and technologists were superficial, misleading, and sometimes reflected ignorance. The findings demonstrate that the IST program stimulated a positive effect on students' images. Their preconceptions were altered in several dimensions: in the cognitive dimension, from superficial and vague to precise and correct images; in the perceptive dimension, from stereotypic to rational and open-minded images; and in the affective dimension, from negative to positive attitudes.

This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher-students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants' instruction with computer technology was ( Teacher) initiation-( Student and Teacher) response sequences-( Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers' learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers' own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.

The Planetary Science Division (PSD) within the National Aeronautics and Space Administrations (NASA) Science Mission Directorate (SMD) at NASA Headquarters sought to understand how to better realize a scientific return on spacecraft system technology investments currently being funded. In order to achieve this objective, a team at NASA Glenn Research Center was tasked with surveying the science and mission communities to collect their insight on technology infusion and additionally sought inputs from industry, universities, and other organizations involved with proposing for future PSD missions. This survey was undertaken by issuing a Request for Information (RFI) activity that requested input from the proposing community on present technology infusion efforts. The Technology Infusion Study was initiated in March 2013 with the release of the RFI request. The evaluation team compiled and assessed this input in order to provide PSD with recommendations on how to effectively infuse new spacecraft systems technologies that it develops into future competed missions enabling increased scientific discoveries, lower mission cost, or both. This team is comprised of personnel from the Radioisotope Power Systems (RPS) Program and the In-Space Propulsion Technology (ISPT) Program staff.The RFI survey covered two aspects of technology infusion: 1) General Insight, including: their assessment of barriers to technology infusion as related to infusion approach; technology readiness; information and documentation products; communication; integration considerations; interaction with technology development areas; cost-capped mission areas; risk considerations; system level impacts and implementation; and mission pull. 2) Specific technologies from the most recent PSD Announcements of Opportunities (AOs): The Advanced Stirling Radioisotope Generator (ASRG), aerocapture and aeroshell hardware technologies, the NASA Evolutionary Xenon Thruster (NEXT) ion propulsion system, and the

Carbon dioxide sequestration by mineral carbonation. Feasibility of enhanced natural weathering as a CO2 emission reduction technology

A possible technology that can contribute to the reduction of carbon dioxide emissions is CO2 sequestration by mineral carbonation. The basic concept behind mineral CO2 sequestration is the mimicking of natural weathering processes in which calcium or magnesium containing minerals react with gaseous CO2 and form solid calcium or magnesium carbonates. Potential advantages of mineral CO2 sequestration compared to, e.g., geological CO2 storage include (1) the permanent and inherently safe sequestration of CO2, due to the thermodynamic stability of the carbonate product formed and (2) the vast potential sequestration capacity, because of the widespread and abundant occurrence of suitable feedstock. In addition, carbonation is an exothermic process, which potentially limits the overall energy consumption and costs of CO2 emission reduction. However, weathering processes are slow, with timescales at natural conditions of thousands to millions of years. For industrial implementation, a reduction of the reaction time to the order of minutes has to be achieved by developing alternative process routes. The aim of this thesis is an investigation of the technical, energetic, and economic feasibility of CO2 sequestration by mineral carbonation. In Chapter 1 the literature published on CO2 sequestration by mineral carbonation is reviewed. Among the potentially suitable mineral feedstock for mineral CO2 sequestration, Ca-silicates, more particularly wollastonite (CaSiO3), a mineral ore, and steel slag, an industrial alkaline solid residue, are selected for further research. Alkaline Ca-rich residues seem particularly promising, since these materials are inexpensive and available near large industrial point sources of CO2. In addition, residues tend to react relatively rapidly with CO2 due to their (geo)chemical instability. Various process routes have been proposed for mineral carbonation, which often include a pre-treatment of the solid feedstock (e.g., size reduction and
