    Data Analytics applications have made successful strides in the business world where co-analyzing extremely large sets of independent variables have proven profitable. Today, most data analytics tools and techniques, sometimes applicable to Earth science, have targeted the business industry. In fact, the literature is nearly absent of discussion about Earth science data analytics. Earth science data analytics (ESDA) is the process of examining large amounts of data from a variety of sources to uncover hidden patterns, unknown correlations, and other useful information. ESDA is most often applied to data preparation, data reduction, and data analysis. Co-analysis of increasing number and volume of Earth science data has become more prevalent ushered by the plethora of Earth science data sources generated by US programs, international programs, field experiments, ground stations, and citizen scientists.Through work associated with the Earth Science Information Partners (ESIP) Federation, ESDA types have been defined in terms of data analytics end goals. Goals of which are very different than those in business, requiring different tools and techniques. A sampling of use cases have been collected and analyzed in terms of data analytics end goal types, volume, specialized processing, and other attributes. The goal of collecting these use cases is to be able to better understand and specify requirements for data analytics tools and techniques yet to be implemented. This presentation will describe the attributes and preliminary findings of ESDA use cases, as well as provide early analysis of data analytics toolstechniques requirements that would support specific ESDA type goals. Representative existing data analytics toolstechniques relevant to ESDA will also be addressed.

  10. From digital positivism and administrative big data analytics towards critical digital and social media research!

    OpenAIRE

    Fuchs, Christian

    2017-01-01

    This essay argues for a paradigm shift in the study of the Internet and digital/social media. Big data analytics is the dominant paradigm. It receives large amounts of funding, is administrative and a form of digital positivism. Critical social media research is an alternative approach that combines critical social media theory, critical digital methods and critical-realist social media research ethics. Strengthening the second approach is a material question of power in academia.

  11. The Planets Testbed: Science for Digital Preservation

    Directory of Open Access Journals (Sweden)

    Seamus Ross

    2008-06-01

    Full Text Available The preservation of digital objects requires specific software tools or services. These can be characterisation tools that abstract the essential characteristics of a digital object from a file, migration tools that convert digital objects to different formats, or emulation tools that render digital objects in their original context on a new infrastructure. Until recently digital preservation has been characterised by practices and processes that could best be described as more art and craft than science. The Planets Testbed provides a controlled environment where preservation tools can be tested and evaluated, and where experiment results can be empirically compared. This paper presents an overview of the Testbed application, an analysis of the experiment methodology and a description of the Testbed's web service approach.

    The United States Environmental Protection Agency's (US EPA) digital science "enterprise" plays a critical role in US EPA's efforts to achieve its mission to protect human health and the environment. This enterprise is an evolving cross-disciplinary research and development construct, with social and institutional dimensions. It has an active development community and produces a portfolio of digital science products including decision support tools, data repositories, Web interfaces, and more. Earth sciences and sustainable development organizations from around the world - including US government agencies - have achieved various levels of success in taking advantage of the rapidly-evolving digital age. Efficiency, transparency and ability to innovate are tied to an organization's digital maturity and related social characteristics. Concepts like participatory web, data and software interoperability, global technology transfer, ontological harmonization, big data, scaling, re-use and open science are no longer "new and emerging." They have emerged and - in some cases - are tied to US government directives. We assess maturity, describe future scenarios, discuss new initiatives and outline steps for better leveraging the information age to more effectively and efficiently achieve US EPA's mission. The views expressed herein are those of the authors and do not necessarily reflect the views or policies of the organizations for which they work and/or represent.

    In partnernship with a pilot program of K12 teachers, we are significantly reshaping the traditional manner which astronomy is taught. Our focus is to incoporate the use of modern digital detectors and data analysis directly into the curriculum. The main goal of this project is to allow students to do real observations, either by remote observation with the Pine Mountain Observatory (PMO) 1-m telescope, or by accessing the HST digital archive. To assist students with data reduction we will provide them with JAVA reduction tools already under development. We will also train teachers on how to use this digital machinery in an effective manner so as to activate the innate curiosity of students and to instill in them an appreciation for the process of science. Our project will emphasize active student experimentation and collaboration (through coordinated observations). All results and observations will be maintained and archived on the Web server in residence at PMO.

  17. Between technical features and analytic capabilities: Charting a relational affordance space for digital social analytics

    Directory of Open Access Journals (Sweden)

    Anders Koed Madsen

    2015-01-01

    Full Text Available Digital social analytics is a subset of Big Data methods that is used to understand the social environment in which people and organizations have to act. This paper presents an analysis of eight projects that are experimenting with the use of these methods for various purposes. It shows that two specific technological features influence the work with such methods in all the cases. The first concerns the need to distribute choices about the structure of data to third-party actors and the second concerns the need to balance machine intelligence and human intuition when automating the analysis. These features set specific conditions for knowledge production, and the paper identifies two opposite approaches for engaging with each of these conditions. These features and approaches are finally combined into a two-dimensional affordance space that illustrates how there is flexibility in the way project leaders interact with the features of the data environment. It thereby also shows how digital social analytics come to have different affordances for different projects.

  2. Digital Curation for Science, Digital Libraries, and Individuals

    Directory of Open Access Journals (Sweden)

    Neil Beagrie

    2006-11-01

    Full Text Available The creation, management and use of digital materials are of increasing importance for a wide range of activities. Much of the knowledge base and intellectual assets of institutions and individuals are now in digital form. The term digital curation is increasingly being used for the actions needed to add value to and maintain these digital assets over time for current and future generations of users. The paper explores this emerging field of digital curation as an area of inter-disciplinary research and practice, and the trends which are influencing its development. It analyses the genesis of the term and how traditional roles relating to digital assets are in transition. Finally it explores some of the drivers for curation ranging from trends such as exponential growth in digital information, to "life-caching", digital preservation, the Grid and new opportunities for publishing, sharing, and re-using data. It concludes that significant effort needs to be put into developing a persistent information infrastructure for digital materials and into developing the digital curation skills of researchers and information professionals. Without this, current investment in digitisation and digital content will only secure short-term rather than lasting benefits.

    2010-05-01

    This SPLINT (SPatial Literacy IN Teaching) supported project is developing pedagogies for the introduction of teaching of digital geological mapping to Earth Science students. Traditionally students are taught to make geological maps on a paper basemap with a notebook to record their observations. Learning to use a tablet pc with GIS based software for mapping and data recording requires emphasis on training staff and students in specific GIS and IT skills and beneficial adjustments to the way in which geological data is recorded in the field. A set of learning and teaching materials are under development to support this learning process. Following the release of the British Geological Survey's Sigma software we have been developing generic methodologies for the introduction of digital geological mapping to students that already have experience of mapping by traditional means. The teaching materials introduce the software to the students through a series of structured exercises. The students learn the operation of the software in the laboratory by entering existing observations, preferably data that they have collected. Through this the students benefit from being able to reflect on their previous work, consider how it might be improved and plan new work. Following this they begin fieldwork in small groups using both methods simultaneously. They are able to practise what they have learnt in the classroom and review the differences, advantages and disadvantages of the two methods, while adding to the work that has already been completed. Once the field exercises are completed students use the data that they have collected in the production of high quality map products and are introduced to the use of integrated digital databases which they learn to search and extract information from. The relatively recent development of the technologies which underpin digital mapping also means that many academic staff also require training before they are able to deliver the

  6. Earth Science Data Analytics: Preparing for Extracting Knowledge from Information

    Science.gov (United States)

    Kempler, Steven; Barbieri, Lindsay

    2016-01-01

    Data analytics is the process of examining large amounts of data of a variety of types to uncover hidden patterns, unknown correlations and other useful information. Data analytics is a broad term that includes data analysis, as well as an understanding of the cognitive processes an analyst uses to understand problems and explore data in meaningful ways. Analytics also include data extraction, transformation, and reduction, utilizing specific tools, techniques, and methods. Turning to data science, definitions of data science sound very similar to those of data analytics (which leads to a lot of the confusion between the two). But the skills needed for both, co-analyzing large amounts of heterogeneous data, understanding and utilizing relevant tools and techniques, and subject matter expertise, although similar, serve different purposes. Data Analytics takes on a practitioners approach to applying expertise and skills to solve issues and gain subject knowledge. Data Science, is more theoretical (research in itself) in nature, providing strategic actionable insights and new innovative methodologies. Earth Science Data Analytics (ESDA) is the process of examining, preparing, reducing, and analyzing large amounts of spatial (multi-dimensional), temporal, or spectral data using a variety of data types to uncover patterns, correlations and other information, to better understand our Earth. The large variety of datasets (temporal spatial differences, data types, formats, etc.) invite the need for data analytics skills that understand the science domain, and data preparation, reduction, and analysis techniques, from a practitioners point of view. The application of these skills to ESDA is the focus of this presentation. The Earth Science Information Partners (ESIP) Federation Earth Science Data Analytics (ESDA) Cluster was created in recognition of the practical need to facilitate the co-analysis of large amounts of data and information for Earth science. Thus, from a to

  7. The role of analytical science in natural resource decision making

    Science.gov (United States)

    Miller, Alan

    1993-09-01

    There is a continuing debate about the proper role of analytical (positivist) science in natural resource decision making. Two diametrically opposed views are evident, arguing for and against a more extended role for scientific information. The debate takes on a different complexion if one recognizes that certain kinds of problem, referred to here as “wicked” or “trans-science” problems, may not be amenable to the analytical process. Indeed, the mistaken application of analytical methods to trans-science problems may not only be a waste of time and money but also serve to hinder policy development. Since many environmental issues are trans-science in nature, then it follows that alternatives to analytical science need to be developed. In this article, the issues involved in the debate are clarified by examining the impact of the use of analytical methods in a particular case, the spruce budworm controversy in New Brunswick. The article ends with some suggestions about a “holistic” approach to the problem.

  10. Knowledge machines digital transformations of the sciences and humanities

    CERN Document Server

    Meyer, Eric T

    2015-01-01

    In Knowledge Machines, Eric Meyer and Ralph Schroeder argue that digital technologies have fundamentally changed research practices in the sciences, social sciences, and humanities. Meyer and Schroeder show that digital tools and data, used collectively and in distributed mode -- which they term e-research -- have transformed not just the consumption of knowledge but also the production of knowledge. Digital technologies for research are reshaping how knowledge advances in disciplines that range from physics to literary analysis. Meyer and Schroeder map the rise of digital research and offer case studies from many fields, including biomedicine, social science uses of the Web, astronomy, and large-scale textual analysis in the humanities. They consider such topics as the challenges of sharing research data and of big data approaches, disciplinary differences and new forms of interdisciplinary collaboration, the shifting boundaries between researchers and their publics, and the ways that digital tools promote o...

    2000-09-21

    Likedlessentid sciences, anal~cd chetis~continues toreinvent itself. Moving beyond its traditional roles of identification and quantification, analytical chemistry is now expanding its frontiers into areas previously reserved to other disciplines. This work describes several research efforts that lie at the new interfaces between analytical chemistry and two of these disciplines, namely materials science and biology. In the materials science realm, the search for new materials that may have useful or unique chromatographic properties motivated the synthesis and characterization of electrically conductive sol-gels. In the biology realm, the search for new surface fabrication schemes that would permit or even improve the detection of specific biological reactions motivated the design of miniaturized biological arrays. Collectively, this work represents some of analytical chemistry’s newest forays into these disciplines. The introduction section to this dissertation provides a literature review on several of the key aspects of this work. In advance of the materials science discussion, a brief introduction into electrochemically-modulated liquid chromatography (EMLC) and sol-gel chemistry is provided. In advance of the biological discussions, brief overviews of scanning force microscopy (SFM) and the oxidative chemistry used to construct our biological arrays are provided. This section is followed by four chapters, each of which is presented as a separate manuscript, and focuses on work that describes some of our cross-disciplinary efforts within materials science and biology. This dissertation concludes with a general summary and future prospectus.

    2010-01-01

    We introduce a new visual analytic approach to the study of scientific discoveries and knowledge diffusion. Our approach enhances contemporary co-citation network analysis by enabling analysts to identify co-citation clusters of cited references intuitively, synthesize thematic contexts in which these clusters are cited, and trace how research focus evolves over time. The new approach integrates and streamlines a few previously isolated techniques such as spectral clustering and feature selection algorithms. The integrative procedure is expected to empower and strengthen analytical and sense making capabilities of scientists, learners, and researchers to understand the dynamics of the evolution of scientific domains in a wide range of scientific fields, science studies, and science policy evaluation and planning. We demonstrate the potential of our approach through a visual analysis of the evolution of astronomical research associated with the Sloan Digital Sky Survey (SDSS) using bibliographic data between 1...

    In this paper, we introduce a Web-based visual analytics framework for democratizing advanced visualization and analysis capabilities pertinent to large-scale earth system simulations. We address significant limitations of present climate data analysis tools such as tightly coupled dependencies, ineffi- cient data movements, complex user interfaces, and static visualizations. Our Web-based visual analytics framework removes critical barriers to the widespread accessibility and adoption of advanced scientific techniques. Using distributed connections to back-end diagnostics, we minimize data movements and leverage HPC platforms. We also mitigate system dependency issues by employing a RESTful interface. Our framework embraces the visual analytics paradigm via new visual navigation techniques for hierarchical parameter spaces, multi-scale representations, and interactive spatio-temporal data mining methods that retain details. Although generalizable to other science domains, the current work focuses on improving exploratory analysis of large-scale Community Land Model (CLM) and Community Atmosphere Model (CAM) simulations.

    This article argues against the assumption that agency and reflexivity disappear in an age of 'algorithmic power' (Lash 2007). Following the suggestions of Beer (2009), it proposes that, far from disappearing, new forms of agency and reflexivity around the embedding in everyday practice of not only algorithms but also analytics more broadly are emerging, as social actors continue to pursue their social ends but mediated through digital interfaces: this is the consequence of many social actors now needing their digital presence, regardless of whether they want this, to be measured and counted. The article proposes 'social analytics' as a new topic for sociology: the sociological study of social actors' uses of analytics not for the sake of measurement itself (or to make profit from measurement) but in order to fulfil better their social ends through an enhancement of their digital presence. The article places social analytics in the context of earlier debates about categorization, algorithmic power, and self-presentation online, and describes in detail a case study with a UK community organization which generated the social analytics approach. The article concludes with reflections on the implications of this approach for further sociological fieldwork in a digital world.

    What is the organizational impact of becoming a digital library, as well as a physical entity with facilities and collections? Is the digital library an add-on or an integrated component of the overall library package? Librarians see sweeping environmental and technological changes. The staff members feel exhilarated and challenged by the pressures to adapt quickly and effectively. Librarians recognize that a Web presence, like other technology components, must be continuously enhanced and regularly re-engineered. The Health Sciences Library, University of North Carolina at Chapel Hill, is reinventing its digital presence to better meet the needs of the community. This paper provides a case study focusing on major changes in planning processes, organizational structure, staffing, budgeting, training, communications, and operations at the Health Sciences Library.

    Currently, the analysis of large data collections is executed through traditional computational and data analysis approaches, which require users to bring data to their desktops and perform local data analysis. Data collection, archiving and analysis from future remote sensing missions, be it from earth science satellites, planetary robotic missions, or massive radio observatories may not scale as more capable instruments stress existing architectural approaches and systems due to more continuous data streams, data from multiple observational platforms, and measurements and models from different agencies. A new paradigm is needed in order to increase the productivity and effectiveness of scientific data analysis. This paradigm must recognize that architectural choices, data processing, management, analysis, etc are interrelated, and must be carefully coordinated in any system that aims to allow efficient, interactive scientific exploration and discovery to exploit massive data collections. Future observational systems, including satellite and airborne experiments, and research in climate modeling will significantly increase the size of the data requiring new methodological approaches towards data analytics where users can more effectively interact with the data and apply automated mechanisms for data reduction, reduction and fusion across these massive data repositories. This presentation will discuss architecture, use cases, and approaches for developing a big data analytics strategy across multiple science disciplines.

    An upgrade to the very-long-baseline-interferometry (VLBI) science receiver (VSR) a radio receiver used in NASA's Deep Space Network (DSN) is currently being implemented. The current VSR samples standard DSN intermediate- frequency (IF) signals at 256 MHz and after digital down-conversion records data from up to four 16-MHz baseband channels. Currently, IF signals are limited to the 265-to-375-MHz range, and recording rates are limited to less than 80 Mbps. The new digital front end, denoted the Wideband VSR, provides improvements to enable the receiver to process wider bandwidth signals and accommodate more data channels for recording. The Wideband VSR utilizes state-of-the-art commercial analog-to-digital converter and field-programmable gate array (FPGA) integrated circuits, and fiber-optic connections in a custom architecture. It accepts IF signals from 100 to 600 MHz, sampling the signal at 1.28 GHz. The sample data are sent to a digital processing module, using a fiber-optic link for isolation. The digital processing module includes boards designed around an Advanced Telecom Computing Architecture (ATCA) industry-standard backplane. Digital signal processing implemented in FPGAs down-convert the data signals in up to 16 baseband channels with programmable bandwidths from 1 kHz to 16 MHz. Baseband samples are transmitted to a computer via multiple Ethernet connections allowing recording to disk at rates of up to 1 Gbps.

    In many domains such as climate and astrophysics, scientific data is often n-dimensional and requires tools that support specialized data types and primitives if it is to be properly stored, accessed, analysed and visualized. Currently, scientific data analytics relies on domain-specific software and libraries providing a huge set of operators and functionalities. However, most of these software fail at large scale since they: (i) are desktop based, rely on local computing capabilities and need the data locally; (ii) cannot benefit from available multicore/parallel machines since they are based on sequential codes; (iii) do not provide declarative languages to express scientific data analysis tasks, and (iv) do not provide newer or more scalable storage models to better support the data multidimensionality. Additionally, most of them: (v) are domain-specific, which also means they support a limited set of data formats, and (vi) do not provide a workflow support, to enable the construction, execution and monitoring of more complex "experiments". The Ophidia project aims at facing most of the challenges highlighted above by providing a big data analytics framework for eScience. Ophidia provides several parallel operators to manipulate large datasets. Some relevant examples include: (i) data sub-setting (slicing and dicing), (ii) data aggregation, (iii) array-based primitives (the same operator applies to all the implemented UDF extensions), (iv) data cube duplication, (v) data cube pivoting, (vi) NetCDF-import and export. Metadata operators are available too. Additionally, the Ophidia framework provides array-based primitives to perform data sub-setting, data aggregation (i.e. max, min, avg), array concatenation, algebraic expressions and predicate evaluation on large arrays of scientific data. Bit-oriented plugins have also been implemented to manage binary data cubes. Defining processing chains and workflows with tens, hundreds of data analytics operators is the

    Analysis of information from multiple data sources obtained through high resolution instrumental measurements has become a fundamental task in all scientific areas. The development of expert methods able to treat such multi- source data systems, with both large variability and measurement extension, is a key for studying complex scientific phenomena, especially those related to systemic analysis in space and environmental sciences. In this talk, we present a time series generalization introducing the concept of generalized numerical lattice, which represents a discrete sequence of temporal measures for a given variable. In this novel representation approach each generalized numerical lattice brings post-analytical data information. We define a generalized numerical lattice £ as a set of three parameters representing the following data properties: dimensionality, size and post-analytical measure. From this generalization, any multi-source database can be reduced to a closed set of classified time series in spatio-temporal generalized dimensions. As a case study, we show a preliminary application in space science data, highlighting the possibility of a real time analysis expert system. In this particular application, we have selected and analyzed, applying detrended fluctuation analysis (DFA), decimetric solar bursts associated to X flare-classes. The association with geomagnetic activity is also reported. DFA method is performed in the framework of a radio burst automatic monitoring system. Our results may characterize the variability pattern evolution, computing the DFA scaling exponent, scanning the time series by a short windowing before the extreme event. For the first time, the application of systematic fluctuation analysis for space weather purposes is presented.

    The quasi-experimental study investigated sixth and eighth graders' perceptions of science with gender, grade levels, and educational experiences as the variables. The Theory of Planned Behavior (Ajzen, 1985) claims that attitude toward the behavior, subjective norm, and perceived behavioral control play a major role in people's intentions, and these intentions ultimately impact their behavior. The study adopted a quantitative research approach by conducting a science perceptions survey for examining students' self-efficacy in learning science (i.e., perceived behavioral control), value of science (i.e., attitude toward the behavior), motivation in science (i.e., attitude toward the behavior), and perceptions of digital science games in science classes (i.e., perceived behavioral control). A total of 255 participants' responses from four rural Appalachian middle school science classrooms in southeastern Ohio were analyzed through a three-way ANCOVA factorial pre-test and post-test data analysis with experimental and comparison groups. Additionally, the study applied a semi-structured, in-depth interview as a qualitative research approach to further examine STEAM digital science games' and Fellows' impact on students' perceptions of science. Eight students in the experimental group were interviewed. Interview data were analyzed with an inductive method. The results found in the three-way ANCOVA data analysis indicated that the diversity of educational experiences was a significant factor that impacted sixth and eighth graders' perceptions of science. Additionally, the interaction of gender and educational experiences was another significant factor that impacted sixth and eighth graders' perceptions of science. The findings of the two short-answer questions identified the reasons why the participants liked or disliked science, as well as why the participants would or would not choose a career in science. The conclusions of the semi-structured, in-depth interview

    Allen, Gary R.

    Digital interactive textbooks represent a major step forward in the quest to integrate technology into instructional methodology. Because this technology is new, virtually no research has been done as to the response of teachers to this innovation. The purpose of this study was to understand the process of change in relation to implementing these digital interactive textbooks in science classrooms at the high school level. The conceptual framework was based on Senge's theory of organizational change, Rogers' theory of the diffusion of innovations, and Davis' research regarding factors involved in technology acceptance. Participants included 7 science teachers and 2 administrators who were members of a professional learning community at a Title I high school in the southeastern region of the United States. A case study design was used to collect data from teacher and administrator interviews and observations of instructional activities in the classroom and professional learning community meetings. Data were coded, categorized, and analyzed for common themes. Results indicated that the digital interactive textbook was met with teacher apprehension and anxiety regarding the transition from teacher-led to student-led instruction, and this apprehension manifested in resistance. During the course of the study, educators found that the digital interactive textbook engaged students and was demonstrated to be a successful tool of instruction. The study is important because educators will develop a better understanding of how to implement technology innovations in the classroom that minimize teacher resistance to instructional change.

    Full Text Available The transition economies of Eastern Europe present both the opportunities and challenges for companies operating in these markets. On one hand, these countries have a large number of technology savvy young consumers, and on the other, the markets must also take into consideration the macro-environment of a country and market conditions which make the use of certain market technologies more feasible and attractive compared to others. It is certainly true in terms of the timing for introduction of various technologies in a country. Drawing analogy for the “IDITAROD RACE” we develop three different “Sled Dog Team layouts” for market characteristics and technologies for three Eastern European countries, namely, Slovakia, Bulgaria, and Albania. The ten market characteristics included in our research are: digital connectivity divide, economic power, demand type, privacy laws, demographics, and competitive conditions, attitude towards technology, institutional maturity, corporate social responsibility, and corruption. The ten marketing technologies included in our research are: digital profiling, segmentation, websites, and search engines marketing, campaign management, content management, social media, mobile application, digital collaborations, and analytics. Company case studies are analyzed and reported for each of these three countries which support the three models presented in our research.

    Gridded data, such as images, image timeseries, and climate datacubes, today are managed separately from the metadata, and with different, restricted retrieval capabilities. While databases are good at metadata modelled in tables, XML hierarchies, or RDF graphs, they traditionally do not support multi-dimensional arrays.This gap is being closed by Array Databases, pioneered by the scalable rasdaman ("raster data manager") array engine. Its declarative query language, rasql, extends SQL with array operators which are optimized and parallelized on server side. Installations can easily be mashed up securely, thereby enabling large-scale location-transparent query processing in federations. Domain experts value the integration with their commonly used tools leading to a quick learning curve.Earth, Space, and Life sciences, but also Social sciences as well as business have massive amounts of data and complex analysis challenges that are answered by rasdaman. As of today, rasdaman is mature and in operational use on hundreds of Terabytes of timeseries datacubes, with transparent query distribution across more than 1,000 nodes. Additionally, its concepts have shaped international Big Data standards in the field, including the forthcoming array extension to ISO SQL, many of which are supported by both open-source and commercial systems meantime. In the geo field, rasdaman is reference implementation for the Open Geospatial Consortium (OGC) Big Data standard, WCS, now also under adoption by ISO. Further, rasdaman is in the final stage of OSGeo incubation.In this contribution we present array queries a la rasdaman, describe the architecture and novel optimization and parallelization techniques introduced in 2015, and put this in context of the intercontinental EarthServer initiative which utilizes rasdaman for enabling agile analytics on Petascale datacubes.

    2014-12-01

    The digital age has given rise to a post-expert world, which is poses challenges for science communication. Mass communication is shifting from a "broadcast" to "conversation" model, while audiences increasingly are finding information with search tools that create personalized filters showing only news they want to see. Such changes dilute expert voices and strengthen insular "tribal" discourse. We argue that these changes in communication pose particular challenges for science communication around politically charged issues such as climate change, because they create mini-echo chambers that can feed cultural wars. To overcome these challenges the scientific community must rethink how we engage the public. In the post-expert world, we need to shift our mindset from reporting the facts to joining diverse conversations.

    Students at the University of Arizona have a relatively rare opportunity to learn in a state-of-the-art planetarium. Originally opened as a campus planetarium in 1975, the Flandrau Science Center recently expanded into the digital realm. In 2014 Flandrau’s antique Minolta star projector was joined by a full-dome 4K digital projection system powered by a high performance computer cluster. Currently three science courses are taught in the planetarium for non-science majors — stellar astronomy, astrobiology, and planetary science (taught by SJK).The new digital system allows us to take our classes off the surface of Earth on a journey into the cosmos. Databases from dozens of spacecraft missions and deep-space telescopic surveys are tapped by the software to generate a realistic immersive 3D perspective of the universe, from local planets, satellites and rings to distant stars and galaxies all the way out to the limit of the visible universe. Simple clicks of a mouse allow us to change the orientation, trajectory, and speed of the virtual spacecraft, giving our students diverse views of different phenomena.The challenge with this system is harnessing the entertainment aspect for educational purposes. The visualization capabilities allow us to artificially enhance certain features and time scales. For example, the sizes of Earth and the moon can be enlarged on-the-fly to help demonstrate phases and eclipses. Polar axes and latitude lines can be added to Earth as it orbits the sun to help convey the reasons for seasons. Orbital paths can be highlighted to allow students to more accurately comprehend the population of near-Earth asteroids.These new immersive computer-generated visualization techniques have the potential to enhance comprehension in science education, especially for concepts involving 3D spatial and temporal relationships. Whether or not this potential is being realized will require studies to gauge student learning and retention beyond the short

  20. Analytical estimation of laser phase noise induced BER floor in coherent receiver with digital signal processing.

    Vanin, Evgeny; Jacobsen, Gunnar

    2010-03-01

    The Bit-Error-Ratio (BER) floor caused by the laser phase noise in the optical fiber communication system with differential quadrature phase shift keying (DQPSK) and coherent detection followed by digital signal processing (DSP) is analytically evaluated. An in-phase and quadrature (I&Q) receiver with a carrier phase recovery using DSP is considered. The carrier phase recovery is based on a phase estimation of a finite sum (block) of the signal samples raised to the power of four and the phase unwrapping at transitions between blocks. It is demonstrated that errors generated at block transitions cause the dominating contribution to the system BER floor when the impact of the additive noise is negligibly small in comparison with the effect of the laser phase noise. Even the BER floor in the case when the phase unwrapping is omitted is analytically derived and applied to emphasize the crucial importance of this signal processing operation. The analytical results are verified by full Monte Carlo simulations. The BER for another type of DQPSK receiver operation, which is based on differential phase detection, is also obtained in the analytical form using the principle of conditional probability. The principle of conditional probability is justified in the case of differential phase detection due to statistical independency of the laser phase noise induced signal phase error and the additive noise contributions. Based on the achieved analytical results the laser linewidth tolerance is calculated for different system cases.

    We report a case study of two highly qualified science teachers as they implemented laptop computers in their Years 9 and 10 science classes at the beginning of the `Digital Education Revolution,' Australia's national one-to-one laptop program initiated in 2009. When a large-scale investment is made in a significant educational change, it is important to consider teachers perspectives and responses to such change and we draw from sociocultural perspectives for our analysis. Through interviews and classroom observations, our interpretive analysis identified four key tensions and contradictions. These include the following: (1) barriers to innovative science teaching; (2) maintaining classroom and school connectivity; (3) teacher versus student expectations; and (4) changes to classroom management. Analysis leads to implications for the future of this and similar programs. The study shows that while these two teachers were committed to developing and delivering technology-rich science lessons, there were many factors that challenge how the implementation progressed. The findings from this study have implications for the continued engagement of teachers in this and other jurisdictions considering the introduction of one-to-one laptop programs.

    This talk will focus on the changes in communicating science in the last 20 years from the perspective of the same research project. Essentially the rapid innovation in online communication requires the scientist learning and utilizing a new platform of communication each year. To maintain relevant visibility and ongoing research activities requires finding synergy between the two. I will discuss how digital communication has inspired my research efforts. This talk will also examine overall visitation and media impact metrics over this period. From developing a highly visible glacier research web page in 1996, to writing more than 400 blog posts since 2008, and in 2014 utilizing a videographer and illustration artist in the field, this is the story of one scientist's digital communication-media evolution. The three main observations are that: 1) Overall visitation has not expanded as rapidly in the last decade. 2) Contact and cooperation with colleagues has expanded quite rapidly since 2008. 3) Media impact peaked in 2005, but is nearing that peak again. The key factors in visibility and media impact for a "small market" research institution/project has been providing timely and detailed content to collaborative sites, such as RealClimate, BAMS State of the Climate, Climate Denial Crock of the Week, and Skeptical Science that can then be repurposed by the media. A review of the visitor metrics to the digital glacier sites I have maintained from 1996-2014 indicate visibility of each platform has a similar growth curve, transitioning to a plateau, but overall visitation does not increase in kind with the increase in number of platforms. Media metrics is more event driven and does not follow the visitor metric pattern.

    The U.S Department of Energy Light Water Reactor Sustainability (LWRS) Program initiated research in to what is needed in order to provide a roadmap or model for Nuclear Power Plants to reference when building an architecture that can support the growing data supply and demand flowing through their networks. The Digital Architecture project published report Digital Architecture Planning Model (Oxstrand et. al, 2016) discusses things to consider when building an architecture to support the increasing needs and demands of data throughout the plant. Once the plant is able to support the data demands it still needs to be able to provide the data in an easy, quick and reliable method. A common method is to create a “one stop shop” application that a user can go to get all the data they need. The creation of this leads to the need of creating a Seamless Digital Environment (SDE) to integrate all the “siloed” data. An SDE is the desired perception that should be presented to users by gathering the data from any data source (e.g., legacy applications and work management systems) without effort by the user. The goal for FY16 was to complete a feasibility study for data mining and analytics for employing information from computer-based procedures enabled technologies for use in developing improved business analytics. The research team collaborated with multiple organizations to identify use cases or scenarios, which could be beneficial to investigate in a feasibility study. Many interesting potential use cases were identified throughout the FY16 activity. Unfortunately, due to factors out of the research team’s control, none of the studies were initiated this year. However, the insights gained and the relationships built with both PVNGS and NextAxiom will be valuable when moving forward with future research. During the 2016 annual Nuclear Information Technology Strategic Leadership (NITSL) group meeting it was identified would be very beneficial to the industry to

    The SDO instruments (EVE, AIA and HMI) teams have created a digital comic book series for upper elementary and middle school students featuring solar science aficionados Camilla and Colours, 2 cool mascot characters. These comics may be printed or read on mobile devices and are available as a free download. Many teachers are looking for resources to use with their students via the IPad so our collaboration helps supply teachers with a great resource that teaches about solar concepts and helps dispel solar misconceptions. It doesn't come as a surprise to a lot of us, but a recent study confirms what's been theorized for years: Comics are a stronger learning tool than text books. Image-based storytelling is a powerful educational tool. Comics are probably more able to combine story and information simultaneously, more effectively and seamlessly, than almost any other medium. There's also a great potential to incorporate interactive elements into digital versions, so that more information can be presented on certain items on a page. For example, videos, animations and even historic footage and audio can be embedded into digital comics. Really, the possibilities are limited only by the creators' imaginations as to how to find new ways to create a rich experience that is interesting to explore for students. We are excited to unveil this new series of solar science comics that promotes science literacy with upper elementary and middle school students.

    The ORNL Spallation Neutron Source (SNS) provides the most intense pulsed neutron beams in the world for scientific research and development across a broad range of disciplines. SNS experiments produce large volumes of complex data that are analyzed by scientists with varying degrees of experience using 3D visualization and analysis systems. However, it is notoriously difficult to achieve proficiency with 3D visualizations. Because 3D representations are key to understanding the neutron scattering data, scientists are unable to analyze their data in a timely fashion resulting in inefficient use of the limited and expensive SNS beam time. We believe a more intuitive interface for exploring neutron scattering data can be created by combining immersive virtual reality technology with high performance data analytics and human interaction. In this paper, we present our initial investigations of immersive visualization concepts as well as our vision for an immersive visual analytics framework that could lower the barriers to 3D exploratory data analysis of neutron scattering data at the SNS.

    2001-05-01

    The Journal of Earth System Science Education is a new interdisciplinary electronic journal aiming to foster the study of the Earth as a system and promote the development and exchange of interdisciplinary learning resources for formal and informal education. JESSE will serve educators and students by publishing and providing ready electronic access to Earth system and global change science learning resources for the classroom and will provide authors and creators with professional recognition through publication in a peer reviewed journal. JESSE resources foster a world perspective by emphasizing interdisciplinary studies and bridging disciplines in the context of the Earth system. The Journal will publish a wide ranging variety of electronic content, with minimal constraints on format, targeting undergraduate educators and students as the principal readership, expanding to a middle and high school audience as the journal matures. JESSE aims for rapid review and turn-around of resources to be published, with a goal of 12 weeks from submission to publication for resources requiring few changes. Initial publication will be on a quarterly basis until a flow of resource submissions is established to warrant continuous electronic publication. JESSE employs an open peer review process in which authors and reviewers discuss directly the acceptability of a resource for publication using a software tool called the Digital Document Discourse Environment. Reviewer comments and attribution will be available with the resource upon acceptance for publication. JESSE will also implement a moderated peer commentary capability where readers can comment on the use of a resource or make suggestions. In the development phase, JESSE will also conduct a parallel anonymous review of content to validate and ensure credibility of the open review approach. Copyright of materials submitted remains with the author, granting JESSE the non-exclusive right to maintain a copy of the resource

  5. Small format digital photogrammetry for applications in the earth sciences

    Science.gov (United States)

    Rieke-Zapp, Dirk

    2010-05-01

    Small format digital photogrammetry for applications in the earth sciences Photogrammetry is often considered one of the most precise and versatile surveying techniques. The same camera and analysis software can be used for measurements from sub-millimetre to kilometre scale. Such a measurement device is well suited for application by earth scientists working in the field. In this case a small toolset and a straight forward setup best fit the needs of the operator. While a digital camera is typically already part of the field equipment of an earth scientist the main focus of the field work is often not surveying. Lack in photogrammetric training at the same time requires an easy to learn, straight forward surveying technique. A photogrammetric method was developed aimed primarily at earth scientists for taking accurate measurements in the field minimizing extra bulk and weight of the required equipment. The work included several challenges. A) Definition of an upright coordinate system without heavy and bulky tools like a total station or GNS-Sensor. B) Optimization of image acquisition and geometric stability of the image block. C) Identification of a small camera suitable for precise measurements in the field. D) Optimization of the workflow from image acquisition to preparation of images for stereo measurements. E) Introduction of students and non-photogrammetrists to the workflow. Wooden spheres were used as target points in the field. They were more rugged and available in different sizes than ping pong balls used in a previous setup. Distances between three spheres were introduced as scale information in a photogrammetric adjustment. The distances were measured with a laser distance meter accurate to 1 mm (1 sigma). The vertical angle between the spheres was measured with the same laser distance meter. The precision of the measurement was 0.3° (1 sigma) which is sufficient, i.e. better than inclination measurements with a geological compass. The upright

    2012-12-01

    There is a vast terrain of emerging research that explores recent innovations in digital games, particularly as they relate to questions of teaching and learning science. One such game, Citizen Science, was developed to teach players about the practice of citizen science as well as lake ecology. Citizen science is a pedagogy that has a long history within the scientific community, engaging the public in ongoing community and environmental surveys to collect data for existing small-scale studies. More recently, citizen science has gained traction as an educational context for teaching and learning science in ways that connect to students' lives and interests. By placing citizen science within the realm of digital worlds, Matthew Gaydos and Kurt Squire invite new possibilities for knowledge to become more kinetic, moving in multiple directions. In this article we discuss some of the tensions we experienced as we explored the digital game, Citizen Science. We highlight questions about narrative and complexity, emergent game play and transfer to encourage thinking about the development and implementation of games such as Citizen Science.

    2016-08-01

    This article presents our study of science coverage in the digital Spanish press over the last decade. We employed automated information retrieval procedures to create a corpus of 50,763 text units dealing with science and technology, and used automated text-analysis procedures in order to provide a general picture of the structure, characteristics and evolution of science news in Spain. We found between 6% and 7% of science coverage, a clear high proportion of biomedicine and predominance of science over technology, although we also detected an increase in technological content during the second half of the decade. Analysing the extrinsic and intrinsic features of science culture, we found a predominance of intrinsic features that still need further analysis. Our attempt to use specialised software to examine big data was effective, and allowed us to reach these preliminary conclusions.

  3. Part Two: Learning Science Through Digital Video: Student Views on Watching and Creating Videos

    Wade, P.; Courtney, A. R.

    2014-12-01

    The use of digital video for science education has become common with the wide availability of video imagery. This study continues research into aspects of using digital video as a primary teaching tool to enhance student learning in undergraduate science courses. Two survey instruments were administered to undergraduate non-science majors. Survey One focused on: a) What science is being learned from watching science videos such as a "YouTube" clip of a volcanic eruption or an informational video on geologic time and b) What are student preferences with regard to their learning (e.g. using video versus traditional modes of delivery)? Survey Two addressed students' perspectives on the storytelling aspect of the video with respect to: a) sustaining interest, b) providing science information, c) style of video and d) quality of the video. Undergraduate non-science majors were the primary focus group in this study. Students were asked to view video segments and respond to a survey focused on what they learned from the segments. The storytelling aspect of each video was also addressed by students. Students watched 15-20 shorter (3-15 minute science videos) created within the last four years. Initial results of this research support that shorter video segments were preferred and the storytelling quality of each video related to student learning.

    In the digital age, libraries are increasingly being augmented or even replaced by information technology (IT), which is often accompanied by implicit assumptions of objectivity and neutrality, yet the field of science and technology studies (STS) has a long history of studying what values are embedded in IT and how they are embedded.

  8. MASSIVE DATA, THE DIGITIZATION OF SCIENCE, AND REPRODUCIBILITY OF RESULTS

    CERN Document Server

    CERN. Geneva

    2010-01-01

    As the scientific enterprise becomes increasingly computational and data-driven, the nature of the information communicated must change. Without inclusion of the code and data with published computational results, we are engendering a credibility crisis in science. Controversies such as ClimateGate, the microarray-based drug sensitivity clinical trials under investigation at Duke University, and retractions from prominent journals due to unverified code suggest the need for greater transparency in our computational science. In this talk I argue that the scientific method be restored to (1) a focus on error control as central to scientific communication and (2) complete communication of the underlying methodology producing the results, ie. reproducibility. I outline barriers to these goals based on recent survey work (Stodden 2010), and suggest solutions such as the “Reproducible Research Standard” (Stodden 2009), giving open licensing options designed to create an intellectual property framework for scien...

    The formulation and flight test results of an algorithm to detect and isolate the first failure of any one of twelve duplex control sensors being monitored are described. The technique uses like sensor output differences for fault detection while relying upon analytic redundancy relationships among unlike quantities to isolate the faulty sensor. The fault isolation logic utilizes the modified sequential probability ratio test, which explicitly accommodates the inevitable irreducible low frequency errors present in the analytic redundancy residuals. In addition, the algorithm uses sensor output selftest, which takes advantage of the duplex sensor structure by immediately removing a highly erratic sensor from control calculations and analytic redundancy relationships while awaiting a definitive fault isolation decision via analytic redundancy.

  10. Learning Science Through Digital Video: Views on Watching and Creating Videos

    2013-12-01

    In science, the use of digital video to document phenomena, experiments and demonstrations has rapidly increased during the last decade. The use of digital video for science education also has become common with the wide availability of video over the internet. However, as with using any technology as a teaching tool, some questions should be asked: What science is being learned from watching a YouTube clip of a volcanic eruption or an informational video on hydroelectric power generation? What are student preferences (e.g. multimedia versus traditional mode of delivery) with regard to their learning? This study describes 1) the efficacy of watching digital video in the science classroom to enhance student learning, 2) student preferences of instruction with regard to multimedia versus traditional delivery modes, and 3) the use of creating digital video as a project-based educational strategy to enhance learning. Undergraduate non-science majors were the primary focus group in this study. Students were asked to view video segments and respond to a survey focused on what they learned from the segments. Additionally, they were asked about their preference for instruction (e.g. text only, lecture-PowerPoint style delivery, or multimedia-video). A majority of students indicated that well-made video, accompanied with scientific explanations or demonstration of the phenomena was most useful and preferred over text-only or lecture instruction for learning scientific information while video-only delivery with little or no explanation was deemed not very useful in learning science concepts. The use of student generated video projects as learning vehicles for the creators and other class members as viewers also will be discussed.

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

    2015-11-01

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

    The CSIRO Mineral Resources Flagship was established to tackle medium- to long-term challenges facing the Australian mineral industry across the value chain from exploration and mining through mineral processing within the framework of an economically, environmentally and socially sustainable minerals industry. This broad portfolio demands collaboration and data exchange with a broad range of participants and data providers across government, research and industry. It is an ideal environment to link geoscience informatics platforms to application across the resource extraction industry and to unlock the value of data integration between traditionally discrete parts of the minerals digital value chain. Despite the potential benefits, data integration remains an elusive goal within research and industry. Many projects use only a subset of available data types in an integrated manner, often maintaining the traditional discipline-based data 'silos'. Integrating data across the entire minerals digital value chain is an expensive proposition involving multiple disciplines and, significantly, multiple data sources both internal and external to any single organisation. Differing vocabularies and data formats, along with access regimes to appropriate analysis software and equipment all hamper the sharing and exchange of information. AuScope has addressed the challenge of data exchange across organisations nationally, and established a national geosciences information infrastructure using open standards-based web services. Federated across a wide variety of organisations, the resulting infrastructure contains a wide variety of live and updated data types. The community data standards and infrastructure platforms that underpin AuScope provide important new datasets and multi-agency links independent of software and hardware differences. AuScope has thus created an infrastructure, a platform of technologies and the opportunity for new ways of working with and integrating

    The Odyssey Missions orbital maps of near surface ice abundance using neutron spectroscopy (Boynton et al., 2002), the Mars Exploration Rover s confirmation of aqueous processing (Squyres et al., 2004), and the Mars Express detailed infrared maps of specific mineral types that were likely formed in aqueous environments (Bibring et al., 2005) have dramatically expanded our tool set for understanding of aqueous processes on Mars. The 2009 Mars Science Laboratory is designed to extend the "follow the water" crosscutting theme of the Mars Exploration Program toward an even more detailed exploration of habitability - the potential of the Mars environment to support life. The next steps in understanding the habitability of Mars are a more detailed in situ analysis of the chemical state of elements such as C, H, O, N, S, P, Ca, and Fe that are essential for terrestrial life. Of particular interest are experiments that establish definitive mineralogy for a wider range of compounds and those that implement a more comprehensive and sensitive search for organic molecules both in the atmosphere and in surface or near surface rocks, soils, and fines. The recent reports of atmospheric methane in the Martian atmosphere make the organics exploration even more compelling. The substantial mass and power resources of MSL combined with its mobility and powerful sample acquisition and processing tools will enable it to locate a variety of near-surface samples and analyze these in some detail. NASA is presently considering the possibility of landing a second MSL rover in 2011.

    2015-12-01

    In today's technological age, visions for technology integration in the classroom continue to be explored and examined. Digital game-based learning is one way to purposefully integrate technology while maintaining a focus on learning objectives. This case study sought to understand agriscience teachers' experiences implementing digital game-based learning in an introductory animal science course. From interviews with agriscience teachers on their experiences with the game, three themes emerged: (1) the constraints of inadequate and inappropriate technologies, and time to game implementation; (2) the shift in teacher and student roles necessitated by implementing the game; and (3) the inherent competitive nature of learning through the game. Based on these findings, we recommend that pre-service and in-service professional development opportunities be developed for teachers to learn how to implement digital game-based learning effectively. Additionally, with the potential for simulations that address cross-cutting concepts in the next generation science standards, digital game-based learning should be explored in various science teaching and learning contexts.

    California University of Pennsylvania (CalUPA) is unique relative to other undergraduate geoscience programs in that their climate science offerings are varied and inter-woven into an existing meteorology degree program, which aligns with the guidelines established by the American Meteorological Society (AMS). In addition to the rigorous meteorological requirements, the program strives to increase students' climate literacy. At the introductory course level, students are required to use the educational resources offered by the AMS—specifically their weather and climate studies materials, which have recently transitioned to a digital format. The Earth Sciences Program at CalUPA recently incorporated these new digital resources into a climatology course with novel pedagogical variants. These teaching strategies were well received by students and may benefit other climatology courses at similar institutions. For example, students were tasked with expounding upon textbook content from 'Topic In Depth' segments; they were required to present tangential climate topics in a digital presentation. Moreover, students mined the scientific literature listed at the end of each chapter in the text to identify climate scientists immersed in social media. Students were then required to follow these scientists and engage each other within a social media platform. Finally, as a culminating experience, students were required to create digital portfolios (e.g., infographic) related to climate science and the AMS materials. This presentation will further detail CalUPA's climatological course offerings and detail how the AMS resources were connected to course requirements listed herein.

    Klump, Jens

    2010-05-01

    Digital information has become an indispensable part of our cultural and scientific heritage. Scientific findings, historical documents and cultural achievements are to a rapidly increasing extent being presented in electronic form - in many cases exclusively so. However, besides the invaluable advantages offered by this form, it also carries a serious disadvantage: users need to invest a great deal of technical effort in accessing the information. Also, the underlying technology is still undergoing further development at an exceptionally fast pace. The rapid obsolescence of the technology required to read the information combined with the frequently imperceptible physical decay of the media themselves represents a serious threat to preservation of the information content. Many data sets in earth science research are from observations that cannot be repeated. This makes these digital assets particularly valuable. Therefore, these data should be kept and made available for re-use long after the end of the project from which they originated. Since research projects only run for a relatively short period of time, it is advisable to shift the burden of responsibility for long-term data curation from the individual researcher to a trusted data repository or archive. But what makes a trusted data repository? Each trusted digital repository has its own targets and specifications. The trustworthiness of digital repositories can be tested and assessed on the basis of a criteria catalogue. This is the main focus of the work of the nestor working group "Trusted repositories - Certification". It identifies criteria which permit the trustworthiness of a digital repository to be evaluated, both at the organisational and technical levels. The criteria are defined in close collaboration with a wide range of different memory organisations, producers of information, experts and other interested parties. This open approach ensures a high degree of universal validity, suitability for

    Digital evidence is information of probative value that is either stored or transmitted in a digital form. Digital evidence can exist as words (text), sound (audio), or images (video or still pictures). Law enforcement and forensic scientists are faced with collecting and analyzing these new forms of evidence that previously existed on paper or on magnetic tapes. They must apply the law and science to the processes they use. Extrapolating the old processes into the new formats has been proceeding since the 1980's. Regardless of the output format, all digital evidence has a certain commonality. One would assume that the rules of evidence and the scientific approach would also have some common characteristics. Obviously, there is also a divergence due to the differences in outputs. It is time to approach the issues regarding digital evidence in a more deliberate, organized, and scientific manner. The program outlined by the NCFS would explore these various formats, the features common to traditional types of forensic evidence, and their divergent features and explore the scientific basis for handling of digital evidence. Our web site, www.ncfs.org, describes our programs.

We then suggest analytic and conceptual pathways to engage in more critical and empirically founded studies of young...... of understanding learning as a process of patchworking and discusses how we might use this to understand young people’s learning with digital media....... people’s learning in technology and media-rich settings. Based on a study of a group of young ‘Power Users’ it is argued, that conceptualising and analysing learning as a process of patchworking can enhance our knowledge of young people’s learning in such settings. We argue that the analytical approach...... gives us ways of critically investigating young people’s learning in technology and media-rich settings, and study if these are processes of critical, reflexive enquiry where resources are creatively re-appropriated. With departure in an analytical example the paper presents the proposed metaphor...

    2013-12-01

    The purpose of this work is to share our findings in using video gaming technology to facilitate the understanding of basic electromagnetism with middle school students. To this end, we explored the impact of using a game called Supercharged! on middle school students' understanding of electromagnetic concepts compared to students who conducted a more traditional inquiry-oriented investigation of the same concepts. This study was a part of a larger design experiment examining the pedagogical potential of Supercharged! The control group learned through a series of guided inquiry methods while the experimental group played Supercharged! during the laboratory sections of the science course. There was significant difference, F(2,91) = 3.6, p positive learning outcomes, as demonstrated by the increase in test scores from pre- to post-assessment and the student interviews. This study also suggests that a complementary approach, in which video games and hands-on activities are integrated, with each activity informing the other, could be a very powerful technique for supporting student scientific understanding. Further, our findings suggest that game designers should embed meta-cognitive activities such as reflective opportunities into educational video games in order to provide scaffolds for students and to reinforce that they are engaged in an educational learning experience.

  7. Preservation of Earth Science Data History with Digital Content Repository Technology

    Wei, Y.; Pan, J.; Shrestha, B.; Cook, R. B.

    2011-12-01

    An increasing need for derived and on-demand data product in Earth Science research makes the digital content more difficult for providers to manage and preserve and for users to locate, understand, and consume. Specifically, this increasing need presents additional challenges in managing data processing history information and delivering such information to end users. For example, the North American Carbon Program (NACP) Multi-scale Synthesis and Terrestrial Model Intercomparison Project (MsTMIP) chose a modified SYNMAP land cover data as one of the input driver data for participating terrestrial biospheric models. The global 1km resolution SYNMAP data was created by harmonizing 3 remote sensing-based land cover products: GLCC, GLC2000, and the MODIS land cover product. The original SYNMAP land cover data was aggregated into half and quarter degree resolution. It was then enhanced with more detailed grassland and cropland types. Currently, there lacks an effective mechanism to convey this data processing information to different modeling teams for them to determine if a data product meets their needs. It still highly relies on offline human interaction. The NASA-sponsored ORNL DAAC has leveraged the contemporary digital object repository technology to promote the representation, management, and delivery of data processing history and provenance information. Within digital object repository, different data products are managed as objects, with metadata as attributes and content delivery and management services as dissemination methods. Derivation relationships among data products can be semantically referenced between digital objects. Within the repository, data users can easily track a derived data product back to its origin, explorer metadata and documents about each intermediate data product, and discover processing details involved in each derivation step. Coupled with Drupal Web Content Management System, the digital repository interface was enhanced to

  8. Renegotiating the pedagogic contract: Teaching in digitally enhanced secondary science classrooms

    Science.gov (United States)

    Ajayi, Ajibola Oluneye

    This qualitative case study explores the effects of emerging digital technology as a teaching and learning tool in secondary school science classrooms. The study examines three teachers' perspectives on how the use of technology affects the teacher-student pedagogic relationship. The "pedagogic contract" is used as a construct to analyze the changes that took place in these teachers' classrooms amid the use of this new technology. The overarching question for this research is: How was the pedagogic contract renegotiated in three secondary science teachers' classrooms through the use of digitally enhanced science instruction. To answer this question, data was collected via semi-structured teacher interviews, classroom observations, and analysis of classroom documents such as student assignments, tests and Study Guides. This study reveals that the everyday use of digital technologies in these classrooms resulted in a re-negotiated pedagogic contract across three major dimensions: content of learning, method and management of learning activities, and assessment of learning. The extent to which the pedagogic contract was renegotiated varied with each of the teachers studied. Yet in each case, the content of learning was extended to include new topics, and greater depth of learning within the mandated curriculum. The management of learning was reshaped around metacognitive strategies, personal goal-setting, individual pacing, and small-group learning activities. With the assessment of learning, there was increased emphasis on self-directed interactive testing as a formative assessment tool. This study highlights the aspects of science classrooms that are most directly affected by the introduction of digital technologies and demonstrates how those changes are best understood as a renegotiation of the teacher-student pedagogic contract.

    Just as the Digital Library for Earth System Education (DLESE) serves at a catalyst for collaboration among its partner institutions and throughout the Geoscience community, DLESE is also a key partner in the broader collaborative efforts of the National Science Digital Library (NSDL). Established by the National Science Foundation to support continual improvement in science, technology, engineering, and mathematics education, NSDL provides an organized point of access to materials created by a broad range of collaborating partner institutions including universities, museums, professional organizations, government agencies, national research laboratories, and publishers of textbooks and journals. NSDL is a network of content and data-rich collections, educational resources, learning environments, and technology-based tools created to address the needs of educators and learners at all levels (K-12, higher education, and lifelong learning). This session will provide an overview of NSDL and explore the ways in which DLESE's active role in the NSDL community can facilitate collaborations with other Geoscience partners. Presenters will demonstrate online tools that can enhance cooperative learning and engagement with digital library resources. Funding opportunities for the development of future NSDL collections, services, and research will also be discussed.

    Anderle, Heinz; Weber, Alfred

    2016-03-01

    Among "vintage" methods of protein determination, quantitative analytical refractometry has received far less attention than well-established pharmacopoeial techniques based on protein nitrogen content, such as Dumas combustion (1831) and Kjeldahl digestion (1883). Protein determination by quantitative refractometry dates back to 1903 and has been extensively investigated and characterized in the following 30 years, but has since vanished into a few niche applications that may not require the degree of accuracy and precision essential for pharmaceutical analysis. However, because high-resolution and precision digital refractometers have replaced manual instruments, reducing time and resource consumption, the method appears particularly attractive from an economic, ergonomic, and environmental viewpoint. The sample solution can be measured without dilution or other preparation procedures than the separation of the protein-free matrix by ultrafiltration, which might even be omitted for a constant matrix and excipient composition.

    The trisulfur radical anion [S3]˙(-) is well-known from inorganic chemistry textbooks as the blue chromophore in ultramarine blues in which this highly reactive species is trapped in a zeolitic framework. Recent findings have revealed that [S3]˙(-) has a multi-faceted role in a variety of media, including alkali metal-sulfur batteries, aqueous solutions at high temperatures and pressures, and ionic liquids; it has also been used to detect trace amounts of water in organic solvents. This tutorial review illustrates how various physical techniques are used to identify a reactive species in solution and shows how elucidation of electronic structures can be used to explain spectroscopic and structural properties. Examples of the function of [S3]˙(-) in materials science, electrochemistry, analytical chemistry and geochemistry are used to illustrate the widespread influence of this fundamentally important triatomic sulfur species.

    2014-01-01

    Processes of digitization have for years represented a major trend in the developments of modern society but have only recently been related to processes of mediatization. The purpose of this article is to look into the relation between the concepts of mediatization and digitization and to clarify...... what a concept of digital media might add to the understanding of processes of mediatization and what the concept of mediatization might add to the understanding of digital media. It is argued that digital media open an array of new trajectories in human communication, trajectories which were...... not anticipated in previous conceptualizations of media and mediatization. If digital media are to be included, the concept of mediatization has to be revised and new parameters are to be built into the concept of media. At the same time it is argued that the concept of mediatization still provides a variety...

  17. Luminosity dependence of the spatial and velocity distributions of galaxies: Semi-analytic models versus the Sloan Digital Sky Survey

    2008-01-01

    By comparing semi-analytic galaxy catalogues with data from the Sloan Digital Sky Survey (SDSS), we show that current galaxy formation models reproduce qualitatively the dependence of galaxy clustering and pairwise peculiar velocities on luminosity, but some subtle discrepancies with the data still remain. The comparisons are carried out by constructing a large set of mock galaxy redshift surveys that have the same selection function as the SDSS Data Release Four (DR4). The mock surveys are based on two sets of semi-analytic catalogues presented by Croton et al. and Kang et al. From the mock catalogues, we measure the redshift-space projected two-point correlation function, the power spectrum, and the pairwise velocity dispersion (PVD) in Fourier space and in configuration space, for galaxies in different luminosity intervals. We then compare these theoretical predictions with the measurements derived from the SDSS DR4. On large scales and for galaxies brighter than L*, both sets of mock catalogues agree well...

    Climate science is a Big Data domain that is experiencing unprecedented growth. In our efforts to address the Big Data challenges of climate science, we are moving toward a notion of Climate Analytics-as-a-Service (CAaaS). We focus on analytics, because it is the knowledge gained from our interactions with Big Data that ultimately produce societal benefits. We focus on CAaaS because we believe it provides a useful way of thinking about the problem: a specialization of the concept of business process-as-a-service, which is an evolving extension of IaaS, PaaS, and SaaS enabled by Cloud Computing. Within this framework, Cloud Computing plays an important role; however, we it see it as only one element in a constellation of capabilities that are essential to delivering climate analytics as a service. These elements are essential because in the aggregate they lead to generativity, a capacity for self-assembly that we feel is the key to solving many of the Big Data challenges in this domain. MERRA Analytic Services (MERRAAS) is an example of cloud-enabled CAaaS built on this principle. MERRAAS enables MapReduce analytics over NASAs Modern-Era Retrospective Analysis for Research and Applications (MERRA) data collection. The MERRA reanalysis integrates observational data with numerical models to produce a global temporally and spatially consistent synthesis of 26 key climate variables. It represents a type of data product that is of growing importance to scientists doing climate change research and a wide range of decision support applications. MERRAAS brings together the following generative elements in a full, end-to-end demonstration of CAaaS capabilities: (1) high-performance, data proximal analytics, (2) scalable data management, (3) software appliance virtualization, (4) adaptive analytics, and (5) a domain-harmonized API. The effectiveness of MERRAAS has been demonstrated in several applications. In our experience, Cloud Computing lowers the barriers and risk to

    2011-03-07

    Electrosprays or electrospraying is a process by which an aerosol is generated between two charged electrodes. This aerosol generation methodology has been known for well over a century, and has undergone exploration in aerosol and materials sciences, to many other areas of research and development. In one such exploration, electrosprays were partnered with mass spectrometry for the accurate characterisation of molecules. This technology now widely referred to as electrospray ionisation mass spectrometry (ESI MS) significantly contributes to molecular analysis and cancer biology to name a few. In fact these findings were recognised by the Chemistry Nobel Committee in 2002, and have catapulted electrosprays to many areas of research and development. In this review, the author wishes to introduce and discuss another such recent discovery, where electrosprays have been investigated for directly handling living cells and whole organisms. Over the past few years these electrosprays now referred to as "bio-electrosprays" have undergone rigorous developmental studies both in terms of understanding all the associate physical, chemical and biological sciences for completely assessing their effects, if any on the direct handling of living biological materials. Therefore, the review will bring together all the work that has contributed to fully understanding that bio-electrosprays are an inert technology for directly handling living biological materials, while elucidating some unique features they possess over competing technologies. Hence, demonstrating this approach as a flexible methodology for a wide range of applications spanning bio-analytics, diagnostics to the possible creation of synthetic tissues, for repairing and replacing damaged/ageing tissues, to the targeted and controlled delivery of personalised medicine through experimental and/or medical cells and/or genes. Therefore, elucidating the far reaching ramifications bio-electrosprays have to our health sciences

    This paper examines the impacts of technology (e.g., Chromebooks, Google Drive) on teacher learning and student activity in the development and implementation of a deeply digital high school biology unit. Using design-based implementation research, teachers co-designed with researchers and curriculum specialists a student-centered unit aligned to the Next Generation Science Standards (NGSS) that utilizes classroom technology. Qualitative and quantitative data were collected to understand the barriers that inhibit the implementation of a digital curriculum as well as the extent that teachers engage in the design process and begin to make shifts in their practice. We found that through the co-design process teachers began to shift their knowledge of NGSS, technology implementation, and adapted to tensions and barriers inherent in the process.

    2005-03-01

    One example of the reality facing science educators is the practical impossibility of providing meaningful laboratory experience in large introductory undergraduate science courses. The Materials Digital Library (MatDL), as part of the National Science Foundation (NSF) National Science Digital Library (NSDL) program, investigates issues associated with the delivery of content in materials science and its cognate areas. The focus of the current work is to investigate the feasibility of using data archived in digital libraries to provide freshmen in large introductory science classes a virtual laboratory experience that meets many of the educational objectives of classical laboratory offerings. Also, the question of scalability and broader applicability, e.g., to freshman physics, is under study. The results of a new pilot project launched this academic year will be reported. The virtual laboratory is associated with ``Introduction to Solid State Chemistry 3.091,'' a course that over half the freshman class at MIT choose to satisfy the chemistry requirement but which lacks a laboratory component.

    High-resolution soil property maps are one major prerequisite for the specific protection of soil functions and restoration of degraded soils as well as sustainable land use, water and environmental management. To generate such maps the combination of digital soil mapping approaches and remote as well as proximal soil sensing techniques is most promising. However, a feasible and reliable combination of these technologies for the investigation of large areas (e.g. catchments and landscapes) and the assessment of soil degradation threats is missing. Furthermore, there is insufficient dissemination of knowledge on digital soil mapping and proximal soil sensing in the scientific community, to relevant authorities as well as prospective users. As one consequence there is inadequate standardization of techniques. At the poster we present the EU collaborative project iSOIL within the 7th framework program of the European Commission. iSOIL focuses on improving fast and reliable mapping methods of soil properties, soil functions and soil degradation risks. This requires the improvement and integration of advanced soil sampling approaches, geophysical and spectroscopic measuring techniques, as well as pedometric and pedophysical approaches. The focus of the iSOIL project is to develop new and to improve existing strategies and innovative methods for generating accurate, high resolution soil property maps. At the same time the developments will reduce costs compared to traditional soil mapping. ISOIL tackles the challenges by the integration of three major components: (i)high resolution, non-destructive geophysical (e.g. Electromagnetic Induction EMI; Ground Penetrating Radar, GPR; magnetics, seismics) and spectroscopic (e.g., Near Surface Infrared, NIR) methods, (ii)Concepts of Digital Soil Mapping (DSM) and pedometrics as well as (iii)optimized soil sampling with respect to profound soil scientific and (geo)statistical strategies. A special focus of iSOIL lies on the

    Full Text Available Taking photographs to document the experiences of an educational field trip is becoming a common activity for teachers and students alike. Considering the regular creation of photographic artifacts, our goal in this paper is to explore students’ picture taking behavior and their recollections of science content associated with their photographs. In this study, we partnered with a class of fifth-grade students in the United States and provided each student with a digital camera to document their experiences during an environmental science field trip at a national park. We report the frequency of photography behaviors according to which activities were most often documented by the students and specifically that students tended to document more of their experiences when they were in outdoor, natural spaces rather than inside of visitor centers or museums. Also, through an analysis of students’ comments about the science content captured in their photographs we observe that students’ comments about photographs of the outdoors tended to show greater depth and complexity than those that were taken in indoor, museum-like spaces.

    2017-03-01

    In digital breast tomosynthesis and digital mammography, the x-ray beam filter material and thickness vary between systems. Replacing K-edge filters with Al was investigated with the intent to reduce exposure duration and to simplify system design. Tungsten target x-ray spectra were simulated with K-edge filters (50 µm Rh; 50 µm Ag) and Al filters of varying thickness. Monte Carlo simulations were conducted to quantify the x-ray scatter from various filters alone, scatter-to-primary ratio (SPR) with compressed breasts, and to determine the radiation dose to the breast. These data were used to analytically compute the signal-difference-to-noise ratio (SDNR) at unit (1 mGy) mean glandular dose (MGD) for W/Rh and W/Ag spectra. At SDNR matched between K-edge and Al filtered spectra, the reductions in exposure duration and MGD were quantified for three strategies: (i) fixed Al thickness and matched tube potential in kilovolts (kV); (ii) fixed Al thickness and varying the kV to match the half-value layer (HVL) between Al and K-edge filtered spectra; and, (iii) matched kV and varying the Al thickness to match the HVL between Al and K-edge filtered spectra. Monte Carlo simulations indicate that the SPR with and without the breast were not different between Al and K-edge filters. Modelling for fixed Al thickness (700 µm) and kV matched to K-edge filtered spectra, identical SDNR was achieved with 37–57% reduction in exposure duration and with 2–20% reduction in MGD, depending on breast thickness. Modelling for fixed Al thickness (700 µm) and HVL matched by increasing the kV over (0,4) range, identical SDNR was achieved with 62–65% decrease in exposure duration and with 2–24% reduction in MGD, depending on breast thickness. For kV and HVL matched to K-edge filtered spectra by varying Al filter thickness over (700, 880) µm range, identical SDNR was achieved with 23–56% reduction in exposure duration and 2–20% reduction in MGD, depending on breast thickness

  11. Evaluation of Visual Analytics Environments: The Road to the Visual Analytics Science and Technology Challenge Evaluation Methodology

    Energy Technology Data Exchange (ETDEWEB)

    2014-09-28

    The evaluation of visual analytics environments was a topic in Illuminating the Path [Thomas 2005] as a critical aspect of moving research into practice. For a thorough understanding of the utility of the systems available, evaluation not only involves assessing the visualizations, interactions or data processing algorithms themselves, but also the complex processes that a tool is meant to support (such as exploratory data analysis and reasoning, communication through visualization, or collaborative data analysis [Lam 2012; Carpendale 2007]). Researchers and practitioners in the field have long identified many of the challenges faced when planning, conducting, and executing an evaluation of a visualization tool or system [Plaisant 2004]. Evaluation is needed to verify that algorithms and software systems work correctly and that they represent improvements over the current infrastructure. Additionally to effectively transfer new software into a working environment, it is necessary to ensure that the software has utility for the end-users and that the software can be incorporated into the end-user’s infrastructure and work practices. Evaluation test beds require datasets, tasks, metrics and evaluation methodologies. As noted in [Thomas 2005] it is difficult and expensive for any one researcher to setup an evaluation test bed so in many cases evaluation is setup for communities of researchers or for various research projects or programs. Examples of successful community evaluations can be found [Chinchor 1993; Voorhees 2007; FRGC 2012]. As visual analytics environments are intended to facilitate the work of human analysts, one aspect of evaluation needs to focus on the utility of the software to the end-user. This requires representative users, representative tasks, and metrics that measure the utility to the end-user. This is even more difficult as now one aspect of the test methodology is access to representative end-users to participate in the evaluation. In many

  12. Evaluation of data analytic approaches to generating cross-domain mappings of controlled science vocabularies

    2015-12-01

    Recent data publication practices have made increasing amounts of diverse datasets available online for the general research community to explore and integrate. Even with the abundance of data online, relevant data discovery and successful integration is still highly dependent upon the data being published with well-formed and understandable metadata. Tagging a dataset with well-known or controlled community terms is a common mechanism to indicate the intended purpose, subject matter, or other relevant facts of a dataset, however controlled domain terminology can be difficult for cross-domain researchers to interpret and leverage. It is also a challenge for integration portals to successfully provide cross-domain search capabilities over data holdings described using many different controlled vocabularies. Mappings between controlled vocabularies can be challenging because communities frequently develop specialized terminologies and have highly specific and contextual usages of common words. Despite this specificity it is highly desirable to produce cross-domain mappings to support data integration. In this contribution we evaluate the applicability of several data analytic techniques for the purpose of generating mappings between hierarchies of controlled science terms. We hope our efforts initiate more discussion on the topic and encourage future mapping efforts.

  13. Nucleic acid distribution pattern in avian erythrocytes and mammalian lymphocytes: comparative studies by fluorescence microscopy and digital imaging analytical techniques.

    Nucleated erythrocytes of healthy domestic chicken and ducks, and lymphocytes of healthy Sprague Dawley rats were evaluated for nucleic acid distribution pattern, employing light and fluorescence microscopy procedures, as well as digital imaging analytical methods. The results demonstrate a unique organization of nuclear DNA of mature chicken and duck erythrocytes, as well as immature duck erythrocytes, as delineated spherical nuclear bodies that mostly corresponded with euchromatin zones of the cells in routine Wright-stain blood smears. The nuclear DNA of the rat lymphocytes, on the other hand, was observed as a more diffuse green fluorescing nuclear areas, with punctate variably-sized diffuse areas of RNA red fluorescence. RNA red color fluorescence was also evident in the narrow cytoplasm of the lymphocytes, especially in large lymphocytes, in comparison with the cytoplasm of the mature avian erythrocytes that completely lacked any nucleic acid fluorescence. Nuclear RNA fluorescence was lacking in the mature chicken erythrocytes, compared with those of the mature and immature duck erythrocytes as well as lymphocytes of both avian and rats blood. The significance of these findings lies in the establishment of normal benchmarks for the nuclear and cytoplasmic nucleic acid pattern in eukaryotic cells. These normal benchmarks become valuable in rapid diagnostic situations associated with pathologies, such as the presence of viral nuclear and cytoplasmic inclusion bodies that can alter the nucleic acid pattern of the host cells, and in conditions of cellular abnormal protein aggregations. Variability of cellular nucleic acid pattern can also aid in prognostic assessments of neoplastic conditions.

    Full Text Available Social science data archives have begun to evolve in 1960’s, thus being one of the pioneers of digital preservation. The Slovenian Data Archive (ADP follows and adjusts best practices that have emerged in this specific field. Its tasks comprise acquisition,processing and long term preservation of valuable primary research data, as well as providing accessibility to the content for users. As in other areas of digital preservation much attention is paid to meeting the requirements of long term preservation as specified in the OAIS (Opean Archival Information System standard, and the use of technological solutions, proposed metadata standards, strategies and policies, and best practices. The purpose of this paper is to present procedures in ADP, to compare them with selected solutions of organizations with the similar mission, and to suggest improvements.Examples are taken from partner organizations within the CESSDA data archives association. These organizations (especially those from the USA, Great Britain and the Netherlands have developed solutions in the field of digital preservation to the highest degree. The paper also reflects on agreed guidelines of reliable services for the archives of research data, which arose in the frame of the FP7 project with the same title (i.e. CESSDA PPP. The results of analysis are useful for all are seeking practical solutions to similar problems.

    Adoption of information and communication technologies and access to the Internet is expanding in Africa, but because of the rapid growth elsewhere, a Digital Divide between Africa and the rest of the world exists, and the gap is growing. In many sub-Saharan African countries, education and research sector suffers some of the worst deficiencies in access to the Internet, despite progress in development of NRENs - National Research and Education (cyber) Networks. By contrast, it is widely acknowledged in policy statements from the African Union, the UN, and others that strength in this very sector provides the key to meeting and sustaining Millennium Development Goals. Developed countries with effective cyber-capabilities proclaim the benefits to rich and poor alike arising from the Information Revolution. This is but a dream for many scientists in African institutions. As the world of science becomes increasingly Internet-dependent, so they become increasingly isolated. eGY-Africa is a bottom-up initiative by African scientists and their collaborators to try to reduce this Digital Divide by a campaign of advocacy for better institutional facilities. Four approaches are being taken. The present status of Internet services, problems, and plans are being mapped via a combination of direct measurement of Internet performance (the PingER Project) and a questionnaire-based survey. Information is being gathered on policy statements and initiatives aimed at reducing the Digital Divide, which can be used for arguing the case for better Internet facilities. Groups of concerned scientists are being formed at the national, regional levels in Africa, building on existing networks as much as possible. Opinion in the international science community is being mobilized. Finally, and perhaps most important of all, eGY-Africa is seeking to engage with the many other programs, initiatives, and bodies that share the goal of reducing the Digital Divide - either as a direct policy

    Tillman, Daniel

    The purpose of this three-paper manuscript dissertation was to study digital fabrication as an instructional technology for supporting elementary and middle school science and mathematics education. Article one analyzed the effects of digital fabrication activities that were designed to contextualize mathematics education at a summer mathematics enrichment program for upper elementary and middle school students. The primary dependent variables studied were the participants' knowledge of mathematics and science content, attitudes towards STEM (science, technology, engineering, and mathematics) and STEM-related careers. Based upon the data collected, three results were presented as having justifiable supporting empirical evidence: (1) The digital fabrication activities, combined with the other mathematics activities at the enrichment program, resulted in non-significant overall gains in students' mathematics test scores and attitudes towards STEM. (2) The digital fabrication activities, combined with the other mathematics activities at the enrichment program, resulted in noteworthy gains on the "Probability & Statistics" questions. (3) Some students who did poorly on the scored paper test on mathematics and science content were nonetheless nominated by their teachers as demonstrating meritorious distinction during the digital fabrication activities (termed "Great Thinkers" by the 5th-grade teachers). Article two focused on how an instructional technology course featuring digital fabrication activities impacted (1) preservice elementary teachers' efficacy beliefs about teaching science, and (2) their attitudes and understanding of how to include instructional technology and digital fabrication activities into teaching science. The research design compared two sections of a teaching with technology course featuring digital fabrication activities to another section of the same course that utilized a media cycle framework (Bull & Bell, 2005) that did not feature digital

    Scientific digital content, including Earth Science observations and model output, has become more heterogeneous in format and more distributed across the Internet. In addition, data and metadata are becoming necessarily linked internally and externally on the Web. As a result, such content has become more difficult for providers to manage and preserve and for users to locate, understand, and consume. Specifically, it is increasingly harder to deliver relevant metadata and data processing lineage information along with the actual content consistently. Readme files, data quality information, production provenance, and other descriptive metadata are often separated in the storage level as well as in the data search and retrieval interfaces available to a user. Critical archival metadata, such as auditing trails and integrity checks, are often even more difficult for users to access, if they exist at all. We investigate the use of several open-source software frameworks to address these challenges. We use Fedora Commons Framework and its digital object abstraction as the repository, Drupal CMS as the user-interface, and the Islandora module as the connector from Drupal to Fedora Repository. With the digital object model, metadata of data description and data provenance can be associated with data content in a formal manner, so are external references and other arbitrary auxiliary information. Changes are formally audited on an object, and digital contents are versioned and have checksums automatically computed. Further, relationships among objects are formally expressed with RDF triples. Data replication, recovery, metadata export are supported with standard protocols, such as OAI-PMH. We provide a tentative comparative analysis of the chosen software stack with the Open Archival Information System (OAIS) reference model, along with our initial results with the existing terrestrial ecology data collections at NASA’s ORNL Distributed Active Archive Center for

    2010-12-01

    The Tasmanian Partnership for Advanced Computing (TPAC) has developed a rich web-based application that publishes large catalogs of scientific datasets. The TPAC Digital Library provides a user interface for viewing, searching, and accessing the catalog data collections, as well as enabling data services for user access. The product also provides management functions for librarians of digital data collections. The search features allow files to be selected graphically based on geospatial extent, or by file name, variable name, attribute value, and by tag. Alternatively, there is a file manager style interface that provides a direct route to the data. The interface is specifically geared towards discovery and access of earth science data files, which makes it intuitive and easy to navigate. Files can be downloaded, or accessed through OPeNDAP, GridFTP, WCS, Matlab and other interfaces. The digital library can harvest metadata from THREDDS, Hyrax, IPCC catalogs and other instances of the digital library. The product is freely available under an open-source license, and is currently deployed by a small but active user base. It has existed since 2005, and remains under constant development by TPAC and other contributors (including the Australian Bureau of Meteorology). Current development initiatives will allow interoperability with library service protocols, as well as other data archive organizations and scientific bodies for data reference transparency. There is a project in progress that will allow the data collection’s owner to attach attribute information, access rights, and meta-data to the data collection to conform to various user community and service standards.

    Searching the World Wide Web for reliable information about specific topics or locations can be frustrating: too many hits, too little relevance. A well-designed digital library, offering a carefully selected collection of online resources, is an attractive alternative to web search engines. The U.S. Geological Survey (USGS) provides three digital libraries for coastal and marine science to serve the needs of a diverse audience--scientists, public servants, educators, and the public.

  1. Managing ocean information in the digital era--events in Canada open questions about the role of marine science libraries.

    Information is the foundation of evidence-based policies for effective marine environmental protection and conservation. In Canada, the cutback of marine science libraries introduces key questions about the role of such institutions and the management of ocean information in the digital age. How vital are such libraries in the mission of studying and protecting the oceans? What is the fate and value of the massive grey literature holdings, including archival materials, much of which is not in digital form but which often contains vital data? How important is this literature generally in the marine environmental sciences? Are we likely to forget the history of the marine pollution field if our digital focus eclipses the need for and access to comprehensive collections and skilled information specialists? This paper explores these and other questions against the backdrop of unprecedented changes in the federal libraries, marine environmental science and legislation in Canada.

    1995-07-01

    In 1990, the University of California, San Francisco, dedicated a new library to serve the faculty, staff, and students and to meet their academic information needs for several decades to come. Major environmental changes present new and additional information management challenges, which can effectively be handled only through the widespread use of computing and computing technologies. Over the next five years, a three-pronged strategy will be followed. We are refining the current physical, paper-based library through the continuous application of technology for modernization and functional improvement. At the same time, we have begun the planning, design, and implementation of a "free-standing" Digital Library of the Health Sciences, focusing on the innovative application of technology. To ensure complementarity and product integrity where the two libraries interface, we will look to technology to transform these separate entities into an eventual, integral whole.

  5. From field data collection to earth sciences dissemination: mobile examples in the digital era

    2015-04-01

    In the framework of the technological and cultural revolution related to the massive diffusion of mobile devices, as smartphones and tablets, the information management and accessibility is changing, and many software houses and developer communities realized applications that can meet various people's needs. Modern collection, storing and sharing of data have radically changed, and advances in ICT increasingly involve field-based activities. Progresses in these researches and applications depend on three main components: hardware, software and web system. Since 2008 the geoSITLab multidisciplinary group (Earth Sciences Department and NatRisk Centre of the University of Torino and the Natural Sciences Museum of the Piemonte Region) is active in defining and testing methods for collecting, managing and sharing field information using mobile devices. Key issues include: Geomorphological Digital Mapping, Natural Hazards monitoring, Geoheritage assessment and applications for the teaching of Earth Sciences. An overview of the application studies is offered here, including the use of Mobile tools for data collection, the construction of relational databases for inventory activities and the test of Web-Mapping tools and mobile apps for data dissemination. The fil rouge of connection is a standardized digital approach allowing the use of mobile devices in each step of the process, which will be analysed within different projects set up by the research group (Geonathaz, EgeoFieldwork, Progeo Piemonte, GeomediaWeb). The hardware component mainly consists of the availability of handheld mobile devices (e.g. smartphones, PDAs and Tablets). The software component corresponds to applications for spatial data visualization on mobile devices, such as composite mobile GIS or simple location-based apps. The web component allows the integration of collected data into geodatabase based on client-server architecture, where the information can be easily loaded, uploaded and shared

    2016-06-01

    Formative assessment strategies are used to direct instruction by establishing where learners' understanding is, how it is developing, informing teachers and students alike as to how they might get to their next set of goals of conceptual understanding. For the science classroom, one rich source of formative assessment data about scientific thinking and practice is in notebooks used during inquiry-oriented activities. In this study, the goal was to better understand how student knowledge was distributed between student drawings and writings about magnetism in notebooks, and how these findings might inform formative assessment strategies. Here, drawing and writing samples were extracted and evaluated from our digital science notebook, with embedded content and laboratories. Three drawings and five writing samples from 309 participants were analyzed using a common ten-dimensional rubric. Descriptive and inferential statistics revealed that fourth-grade student understanding of magnetism was distributed unevenly between writing and drawing. Case studies were then presented for two exemplar students. Based on the rubric we developed, students were able to articulate more of their knowledge through the drawing activities than through written word, but the combination of the two mediums provided the richest understanding of student conceptions and how they changed over the course of their investigations.

    The climate sciences represent a big data domain that is experiencing unprecedented growth. In our efforts to address the big data challenges of climate science, we are moving toward a notion of Climate Analytics-as-a-Service (CAaaS). We focus on analytics, because it is the knowledge gained from our interactions with big data that ultimately product societal benefits. We focus on CAaaS because we believe it provides a useful way of thinking about the problem: a specialization of the concept of business process-as-a-service, which is an evolving extension of IaaS, PaaS, and SaaS enabled by cloud computing. Within this framework, cloud computing plays an important role; however, we see it as only one element in a constellation of capabilities that are essential to delivering climate analytics-as-a-service. These elements are essential because in the aggregate they lead to generativity, a capacity for self-assembly that we feel is the key to solving many of the big data challenges in this domain. This poster will highlight specific examples of CAaaS using climate reanalysis data, high-performance cloud computing, map reduce, and the Climate Data Services API.

  10. How Early Childhood Practitioners Build, Shape, and Construct Their Digital Practices: The Search for an Analytical Space

    Directory of Open Access Journals (Sweden)

    Tove Lafton

    2012-10-01

    Full Text Available This ongoing research examines how early childhood practitioners build, shape, and maintain digital practices through talk and action, assuming shared construction and development of knowledge. Based on empirical data I suggest looking beyond the social situated idea of knowledge building to include multiple elements, like individual knowledge, discourse and materiality, in analyses of the digital practice field in kindergarten. The discussions are both theoretically and empirically driven and tend to create a dynamic context model as a representation of the digital practice field.

  11. Analytical challenges of determining composition and structure in small volumes with applications to semiconductor technology, nanostructures and solid state science

    Ma, Zhiyong; Kuhn, Markus; Johnson, David C.

    2017-03-01

    Determining the structure and composition of small volumes is vital to the ability to understand and control nanoscale properties and critical for advancing both fundamental science and applications, such as semiconductor device manufacturing. While metrology of nanoscale materials (nanoparticles, nanocomposites) and nanoscale semiconductor structures is challenging, both basic research and cutting edge technology benefit from new and enhanced analytical techniques. This focus issue contains articles describing approaches to overcome the challenges in obtaining statistically significant atomic-scale quantification of structure and composition in a variety of materials and devices using electron microscopy and atom probe tomography.

  12. Flight test results for the F-8 digital fly-by-wire aircraft control sensor analytic redundancy management technique

    Science.gov (United States)

    Deckert, J. C.

    1981-01-01

    This paper reviews the formulation and flight test results of an algorithm to detect and isolate the first failure of any one of twelve duplex control sensor signals being monitored. The technique uses like-signal differences for fault detection while relying upon analytic redundancy relationships among unlike quantities to isolate the faulty sensor. The fault isolation logic utilizes the modified sequential probability ratio test, which explicitly accommodates the inevitable irreducible low frequency errors present in the analytic redundancy residuals. In addition, the algorithm uses sensor output selftest, which takes advantage of the duplex sensor structure by immediately removing a highly erratic sensor from control calculations and analytic redundancy relationships while awaiting a definitive fault isolation decision via analytic redundancy. This study represents a proof of concept demonstration of a methodology that can be applied to duplex or higher flight control sensor configurations and, in addition, can monitor the health of one simplex signal per analytic redundancy relationship.

  15. Analytical and Clinical Validation of a Digital Sequencing Panel for Quantitative, Highly Accurate Evaluation of Cell-Free Circulating Tumor DNA.

    Directory of Open Access Journals (Sweden)

    Richard B Lanman

    Full Text Available Next-generation sequencing of cell-free circulating solid tumor DNA addresses two challenges in contemporary cancer care. First this method of massively parallel and deep sequencing enables assessment of a comprehensive panel of genomic targets from a single sample, and second, it obviates the need for repeat invasive tissue biopsies. Digital Sequencing™ is a novel method for high-quality sequencing of circulating tumor DNA simultaneously across a comprehensive panel of over 50 cancer-related genes with a simple blood test. Here we report the analytic and clinical validation of the gene panel. Analytic sensitivity down to 0.1% mutant allele fraction is demonstrated via serial dilution studies of known samples. Near-perfect analytic specificity (> 99.9999% enables complete coverage of many genes without the false positives typically seen with traditional sequencing assays at mutant allele frequencies or fractions below 5%. We compared digital sequencing of plasma-derived cell-free DNA to tissue-based sequencing on 165 consecutive matched samples from five outside centers in patients with stage III-IV solid tumor cancers. Clinical sensitivity of plasma-derived NGS was 85.0%, comparable to 80.7% sensitivity for tissue. The assay success rate on 1,000 consecutive samples in clinical practice was 99.8%. Digital sequencing of plasma-derived DNA is indicated in advanced cancer patients to prevent repeated invasive biopsies when the initial biopsy is inadequate, unobtainable for genomic testing, or uninformative, or when the patient's cancer has progressed despite treatment. Its clinical utility is derived from reduction in the costs, complications and delays associated with invasive tissue biopsies for genomic testing.

    Deckert, J. C.; Desai, M. N.; Deyst, J. J.

    1977-01-01

    In this paper we present a reliable technique for failure detection and identification (FDI) for dual redundant flight control sensors aboard the NASA F-8 digital fly-by-wire (DFBW) aircraft, and we discuss the successful application of the technique to identifying failures injected on test flight telemetry data. The technique exploits the analytic redundancy which exists as relationships among variables being measured by dissimilar instruments. With straightforward modification the technique may be extended to provide failure monitoring of a single remaining sensor after the identified failure of its companion sensor.

  18. Secular and religious: the intrinsic doubleness of analytical psychology and the hegemony of naturalism in the social sciences.

    Science.gov (United States)

    Main, Roderick

    2013-06-01

    In recent years a number of prominent social theorists, including Jürgen Habermas and Charles Taylor, have voiced concern about the hegemony of naturalistic, secular assumptions in the social sciences, and in their different ways have sought to address this by establishing greater parity between secular and religious perspectives. This paper suggests that C.G. Jung's analytical psychology, which hitherto has been largely ignored by social theory, may have something to contribute on this issue as it can be understood coherently both empirically, without reference to transcendent reality, and metaphysically, with reference to transcendent reality. It is argued that, despite his denials of any metaphysical intent, Jung does in fact engage in metaphysics and that together the empirical and metaphysical vectors of his thought result in a rich and distinctive double perspective. This dual secular and religious perspective can be seen as part of Jung's own critique of the hegemony of naturalism and secularism, which for Jung has profound social as well as clinical relevance. The concern and approach that Habermas and Taylor share with Jung on this issue may provide some grounds for increased dialogue between analytical psychology and the social sciences.

  19. Hands on, mobiles on The use of a digital narrative as a scaffolding remedy in a classical science centre

    Directory of Open Access Journals (Sweden)

    Anne Kahr-Højland

    2010-12-01

    Full Text Available This article examines an educational design experiment which aimed to support young people’s involvement and reflection in the exhibition at a Danish science centre. The experiment consisted in the examination of the design and implementation of a mobile phone facilitated narrative, which was planned as a so-called scaffolding remedy in the hands-on based exhibition. The digital narrative, called EGO-TRAP, was developed using Design-Based Research as the overall methodological framework. The study of students’ interactions in the exhibition suggests, among other things, that because of its quality as a digital narrative, EGO-TRAP scaffolds pleasurable engagement and counteracts the tendency of "random button pressing" that often occurs in classical science centre exhibitions. In this connection, the mobile phone plays an essential role due to the fact that it, as the favoured media by the young students, offers an experience which they describe as both personal and flexible.

    Thomas, R. G.; Berry, K.; Arrigo, J.; Hooper, R. P.

    2013-12-01

    Technical 'hands-on' training workshops are designed to bring together scientists, technicians, and program managers from universities, government agencies, and the private sector to discuss methods used and advances made in instrumentation and data analysis. Through classroom lectures and discussions combined with a field-day component, hands-on workshop participants get a 'full life cycle' perspective from instrumentation concepts and deployment to data analysis. Using film to document this process is becoming increasingly more popular, allowing scientists to add a story-telling component to their research. With the availability of high-quality and low priced professional video equipment and editing software, scientists are becoming digital storytellers. The science video developed from the 'hands-on' workshop, Optical Water Quality Sensors for Nutrients: Concepts, Deployment, and Analysis, encapsulates the objectives of technical training workshops for participants. Through the use of still photography, video, interviews, and sound, the short video, An Introduction to CUAHSI's Hands-on Workshops, produced by a co-instructor of the workshop acts as a multi-purpose tool. The 10-minute piece provides an overview of workshop field day activities and works to bridge the gap between classroom learning, instrumentation application and data analysis. CUAHSI 'hands-on' technical workshops have been collaboratively executed with faculty from several universities and with the U.S. Geological Survey. The video developed was designed to attract new participants to these professional development workshops, to stimulate a connection with the environment, to act as a workshop legacy resource, and also serve as a guide for prospective hands-on workshop organizers. The effective use of film and short videos in marketing scientific programs, such as technical trainings, allows scientists to visually demonstrate the technologies currently being employed and to provide a more

    2015-01-01

    This paper explores emerging practices in research data management in the arts, humanities and social sciences (AHSS). It will do so vis-à-vis current citation conventions and impact measurement for research in AHSS. Case study findings on research data inventoried at Goldsmiths', University of London will be presented. Goldsmiths is a UK research-intensive higher education institution which specialises in arts, humanities and social science research. The paper's aim is to raise awareness of the subject-specific needs of AHSS scholars to help inform the design of future digital tools for impact analysis in AHSS. Firstly, I shall explore the definition of research data and how it is currently understood by AHSS researchers. I will show why many researchers choose not to engage with digital dissemination techniques and ORCID. This discussion must necessarily include the idea that practice-based and applied AHSS research are processes which are not easily captured in numerical 'sets' and cannot be labelled electronically without giving careful consideration to what a group or data item 'represents' as part of the academic enquiry, and therefore how it should be cited and analysed as part of any impact assessment. Then, the paper will explore: the role of the monograph and arts catalogue in AHSS scholarship; how citation practices and digital impact measurement in AHSS currently operate in relation to authorship and how digital identifiers may hypothetically impact on metrics, intellectual property (IP), copyright and research integrity issues in AHSS. I will also show that, if we are to be truly interdisciplinary, as research funders and strategic thinkers say we should, it is necessary to revise the way we think about digital research dissemination. This will involve breaking down the boundaries between AHSS and other types of research.

  6. AN ACTIVITY THEORY-BASED ANALYTIC FRAMEWORK FOR THE STUDY OF DISCOURSE IN SCIENCE CLASSROOMS

    Directory of Open Access Journals (Sweden)

    Rodrigo Drumond Vieira

    Full Text Available In this paper we introduce a new framework and methodology to analyze science classroom discourse and apply it to a university physics education course. Two fields of inquiry were adapted to develop the framework: activity theory and linguistics. From activity theory we applied levels of analysis (activity, actions, and operations to organize and structure the discourse analysis. From the field of linguistics we used resources from sociolinguistics and textual linguistics to perform analysis at the action and operation levels. Sociolinguistics gave us criteria to introduce contextualization cues into analysis in order to consider ways that participants segmented their classroom conversations. Textual linguistics provided a basis for categories of language organization (e.g, argumentation, explanation, narration, description, injunction, and dialogue. From this analysis, we propose an examination of a teacher's discourse moves, which we labeled Discursive Didactic Procedures (DDPs. Thus, the framework provides a means to situate these DDPs in different types of language organization, examine the roles such DDPs play in events, and consider the relevant didactic goals accomplished. We applied this framework to analyze the emergence and development of an argumentative situation and investigate its specific DDPs and their roles. Finally, we explore possible contributions of the framework to science education research and consider some of its limitations.

    Science.gov (United States)

    Müller, Larissa; Traub, Heike; Jakubowski, Norbert

    2016-11-01

    Inductively coupled plasma mass spectrometry (ICP-MS) is a well-established analytical method for multi-elemental analysis in particular for elements at trace and ultra-trace levels. It has found acceptance in various application areas during the last decade. ICP-MS is also more and more applied for detection in the life sciences. For these applications, ICP-MS excels by a high sensitivity, which is independent of the molecular structure of the analyte, a wide linear dynamic range and by excellent multi-element capabilities. Furthermore, methods based on ICP-MS offer simple quantification concepts, for which usually (liquid) standards are applied, low matrix effects compared to other conventional bioanalytical techniques, and relative limits of detection (LODs) in the low pg g-1 range and absolute LODs down to the attomol range. In this chapter, we focus on new applications where the multi-element capability of ICP-MS is used for detection of lanthanoides or rare earth elements, which are applied as elemental stains or tags of biomolecules and in particular of antibodies.

    Helly, J.; Miller, S.; Sutton, D.; Clark, D.; Houghton, T.; Chase, A.

    2004-12-01

    This is a report on the construction of a network of digital libraries for the hydrology community as part of the CUAHSI Hydrologic Information System (HIS) based on an architecture developed for the publication of oceanographic data acquired by oceanographic research vessels. Our results show that this architecture and implementation are appropriate for a broad range of scientific disciplines and that the approach scales from the desk of the individual investigator to that of a major research institution and to the interoperation of institutions. We are able to run the entire digital library from a laptop computer as well as from supercomputer-center-size resources. The underlying architecture and prototype set of tools have been developed as a part of the SIOExplorer project (http://SIOExplorer.ucsd.edu), funded by National Science Digital Library (NSDL), Information Technology Research (ITR) and Ocean Science (OCE) awards over the last three years. With funding from the NSF Geosciences Directorate, this approach has been adapted to hydrology and is operating in a multi-site configuration representing a network of hydrological observatories and oceanographic archives. The system is integrated with the GEONgrid (http://geongrid.org) and includes automatic methods of harvesting data and metadata from existing web-sites (e.g., USGS and NASA) as well as real-time and near-real-time sensors through other data systems such as Unidata OpenDAP and Local Data Manager.

    2016-04-01

    Full Text Available Social media posts are full of potential for data mining and analysis. Recognizing this potential, platform providers increasingly restrict free access to such data. This shift provides new challenges for social scientists and other non-profit researchers who seek to analyze public posts with a purpose of better understanding human interaction and improving the human condition. This paper seeks to outline some of the recent changes in social media data analysis, with a focus on Twitter, specifically. Using Twitter data from a 24-hour period following The Sisters in Spirit Candlelight Vigil, sponsored by the Native Women’s Association of Canada, this article compares three free-use Twitter application programming interfaces for capturing tweets and enabling analysis. Although recent Twitter data restrictions limit free access to tweets, there are many dynamic options for social scientists to choose from in the capture and analysis of Twitter and other social media platform data. This paper calls for critical social media data analytics combined with traditional, qualitative methods to address the developing ‘data gold rush.’

    Full Text Available Até bem pouco tempo, os sociólogos resistiam em admitir que as mudanças econômicas e sociais produzidas pela revolução da informática são tão profundas quanto aquelas provocadas pela revolução industrial. Mas, pouco a pouco, vemos desenvolver-se uma sociologia digital. Este artigo inicia examinando, em breves linhas, como a busca e o acesso à literatura, enquanto atividade rotineira, cotidiana, das ciências sociais, transformou-se, a partir das novas tecnologias digitais. Em seguida, o artigo examina especificamente os avanços nas pesquisas do tipo survey, nas entrevistas individuais e nos métodos experimentais, como exemplos das formas em que determinadas abordagens da sociologia se transformaram com o uso de novas tecnologias de informação e comunicação. Assim como a Internet, em uma perspectiva mais ampla, estas novas tecnologias apresentam desafios e oportunidades. Para destacar a ambiguidade da situação, o artigo conclui com uma discussão sobre as oportunidades e desafios que emergem da crescente importância social assumida pelos sites de redes sociais e outras formas de dados digitais, bem como da criação de ferramentas analíticas para garimpar, extrair e codificar estes dados.Up until recently sociologists have been slow to recognize that the economic and social changes produced by the information revolution are as profound as those that came with the industrial revolution. Slowly, however, we have seen the development of a digital sociology. This paper begins by briefly looking at how searching and accessing literature, as a routine, day-to-day social science task, has changed with new, digital technologies. Then, the paper looks specifically at developments in survey research, face-to-face interviewing and experimental methods, as examples of the manner in which particular approaches to sociology have changed with new communication and information technologies. As with the Internet more broadly, these new

    Full Text Available Digital media developments confront the humanities and social sciences with major challenges in exploiting multimedia rich data sets. A critical need is demonstrated to bridge the divide between the building of multimedia digital repositories, and the publishing of research outcomes that exploit the interactive potential of digital media. Software that melds the steps in digital research and publishing, now disparate environments, into a single sequence of integrated procedures can provide a critical innovation for the transformation of digital research and publishing from a quasi-craft-like and demanding set of skills, into a transparent and user-directed flow process. Humanities and social science (HSS researchers who use multimedia data could be working more collaboratively, creatively and with far more international impact. The HSS have not yet exploited the interactive and collaborative potential offered by interactive computer technologies, and the expansion of digital repositories. Digital publishing has opened opportunities to incorporate both interactivity and multimedia into scholarly publishing, permitting new modes of visualization and creating ever mutable texts. Open Source software, can offer an internationally significant break-through in research definition, data collection and management, and interactive publishing, leading to a major paradigm shift in eHumanities and eSocialScience. The article proposes a framework for bridging the gap, overcoming the silo problem and building an interactive multimedia research environment (m.i.r.e..

    2016-10-01

    The purpose of this study is to explore how an online-structured dialogue environment supported (OSDE) collaborative learning about the nature of science among a group of trainee science teachers in the UK. The software used (InterLoc) is a linear text-based tool, designed to support structured argumentation with openers and `dialogue moves'. A design-based research approach was used to investigate multiple sessions using InterLoc with 65 trainee science teachers. Five participants who showed differential conceptual change in terms of their Nature of Science (NOS) views were purposively selected and closely followed throughout the study by using key event recall interviews. Initially, the majority of participants held naïve views of NOS. Substantial and favourable changes in these views were evident as a result of the OSDE. An examination of the development of the five participants' NOS views indicated that the effectiveness of the InterLoc discussions was mediated by cultural, cognitive, and experiential factors. The findings suggest that InterLoc can be effective in promoting reflection and conceptual change.

    2016-05-25

    The ongoing digital revolution is no longer limited to the application of apps on the smart phone for daily needs but starts to affect also our professional life in formulation science. The software platform F-CAD (Formulation-Computer Aided Design) of CINCAP can be used to develop and test in silico capsule and tablet formulations. Such an approach allows the pharmaceutical industry to adopt the workflow of the automotive and aircraft industry. Thus, the first prototype of the drug delivery vehicle is prepared virtually by mimicking the composition (particle size distribution of the active drug substance and of the excipients within the tablet) and the process such as direct compression to obtain a defined porosity. The software is based on a cellular automaton (CA) process mimicking the dissolution profile of the capsule or tablet formulation. To take account of the type of dissolution equipment and all SOPs (Standard Operation Procedures) such as a single punch press to manufacture the tablet, a calibration of the F-CAD dissolution profile of the virtual tablet is needed. Thus, the virtual tablet becomes a copy of the real tablet. This statement is valid for all tablets manufactured within the same formulation design space. For this reason, it is important to define already for Clinical Phase I the formulation design space and to work only within this formulation design space consisting of the composition and the processes during all the Clinical Phases. Thus, it is not recommended to start with a simple capsule formulation as service dosage form and to change later to a market ready tablet formulation. The availability of F-CAD is a necessary, but not a sufficient condition to implement the workflow of the automotive and aircraft industry for developing and testing drug delivery vehicles. For a successful implementation of the new workflow, a harmonization of the equipment and the processes between the development and manufacturing departments is a must. In

    Children and adolescents in developed countries are heavily immersed in digital media, creating an inexpensive, far-reaching marketing opportunity for the food industry and the gaming industry. However, exposure to nonnutritious food and beverage advertisements combined with the use of stationary media create a conflict between entertainment and public health. Using the popular digital gaming platforms advergames (online games that market branded products) and exergames (video games that involves gross motor activity for play) as exemplars, the following article provides an analysis of the negative and positive health impacts of digital gaming as they relate specifically to overweight and obesity outcomes for children and adolescents. Theoretical explanations including the food marketing defense model, persuasion knowledge model, and social cognitive theory are used to explain the influence of gaming on young players’ health. Throughout the article, we discuss the role of public policy to encourage the development and use of health-promoting digital games as an innovative, effective tool to combat the pediatric obesity crisis.

    2004-12-01

    The ERESE (Enduring Resources in Earth Science Education) project involves a close collaboration between teachers, librarians, educators, data archive managers and scientists in Earth sciences and information technology, to create a digital library environment for Earth science education. We report here on an ongoing (NSF-NSDL) project involving teachers' professional development in the pedagogy of plate tectonics in middle and high schools. This work included efforts in scientific database development in terms of contents and search tools, the development of an inquiry based learning approach, a two week professional development workshop attended by 15 teachers from across the nation, a classroom implementation of lesson plans developed by the teachers at the workshop and an evaluation/validation process for the success of their pedagogic approaches. This ERESE project offers a novel path for both science teaching and professional outreach for scientists, and includes four key components: (1) A true, long-term research partnership between educators and scientists, guiding each other with respect to the authenticity of the science taught and the educational soundness of a scientists' elaborations on science concepts. (2) Expansion of existing scientific databases through the use of metadata that tie scientific materials to a particular expert level and teaching goal. (3) The design of interfaces that make data accessible to the educational community. (4) The use of an inquiry based teaching approach that integrates the scientist-educator collaboration and the data base developments. Our pedagogic approach includes the development of a central hypotheses by the student in response to an initial general orientation and presentation of a well chosen central provocative phenomenon by the teacher. Then, the student develops a research plan that is devoted to address this hypothesis through the use of the materials provided by a scientific database allowing a students

    The Ho Tung Visualization Laboratory and Planetarium at Colgate University provides an opportunity for students of diverse backgrounds to learn scientific concepts and communication techniques through the creation of fulldome digital animations. Students give presentations to classes, school groups, and the public in the planetarium setting, and enhance learning by creating digital content appropriate to these audiences. The immersive environment is well-suited for showing large-scale geologic processes that may not be easily seen in the field. Geoscience projects include fly-bys of the Hudson River Valley, Cascade Mountain Range, Grand Canyon, and Basin and Range province, animation of the advance of the Laurentide Ice Sheet, evolution of continental positions since the late Precambrian, and comparisons of volcanic eruption styles. In order to create a digital animation, students must have a detailed understanding of the subject matter as well as all aspects of presentation, ranging from intended audience to relevant production technologies. This encourages students to explore material at a depth beyond conventional learning methods while integrating the skills necessary to effectively communicate scientific concepts to varied audiences. Based on these explorations, it appears beneficial to promote scientific visualization creation as a tool in itself to help students develop both scientific knowledge and communication skills.

  1. The effects of a problem-based learning digital game on continuing motivation to learn science

    Science.gov (United States)

    Toprac, Paul K.

    The purpose of this study was to determine whether playing a problem-based learning (PBL) computer game, Alien Rescue III, would promote continuing motivation (CM) to learn science, and to explore the possible sources of CM. Another goal was to determine whether CM and interest to learn science in the classroom were identical constructs. CM was defined as the pursuit of academic learning goals in noninstructional contexts that were initially encountered in the classroom. Alien Rescue was played for a total of 9 hours in the seventh grade of a private middle school with 44 students, total, participating. The study used a design-based research approach that attempted to triangulate quantitative and qualitative methods. A science knowledge test, and two self-report questionnaires---one measuring motivation and one measuring CM---were administered preintervention, postintervention, and follow-up. Qualitative data was also collected, including student interviews, classroom observations, written responses, and a science teacher interview. Repeated measures ANOVAs were used to determine any significant changes in scores. A multiple regression analysis was used to explore whether a model of CM could be determined using the Eccles' expectancy-value achievement motivation model. The constant comparative method was used to obtain relevant information from the qualitative data. Based on contradictory quantitative and qualitative findings, results were mixed as to whether students exhibited an increase in CM to learn space science. Students continued to freely engage Alien Rescue during the mid-class break, but this does not strictly adhere to the definition of CM. However, many students did find space science more interesting than anticipated and developed increased desire to learn more in class, if not outside of class. Results also suggest that CM and interest in learning more in class are separate but related constructs. Finally, no satisfactory model emerged from the

    2014-06-01

    The development of teachers as reflective practitioners is a central concept in national guidelines for teacher preparation and induction (National Council for Accreditation of Teacher Education 2008). The Teacher Induction Network (TIN) supports the development of reflective practice for beginning secondary science teachers through the creation of online "communities of practice" (Barab et al. in Inf Soc, 237-256, 2003), which have been shown to have positive impacts on teacher collaboration, communication, and reflection. Specifically, TIN integrated the use of asynchronous, video annotation as an affordance to directly facilitate teachers' reflection on their classroom practices (Tripp and Rich in Teach Teach Educ 28(5):728-739, 2013). This study examines the use of video annotation as a tool for developing reflective practices for beginning secondary science teachers. Teachers were enrolled in an online teacher induction course designed to promote reflective practice and inquiry-based instruction. A modified version of the Learning to Notice Framework (Sherin and van Es in J Teach Educ 60(1):20-37, 2009) was used to classify teachers' annotations on video of their teaching. Findings from the study include the tendency of teachers to focus on themselves in their annotations, as well as a preponderance of annotations focused on lower-level reflective practices of description and explanation. Suggestions for utilizing video annotation tools are discussed, as well as design features, which could be improved to further the development of richer annotations and deeper reflective practices.

  5. Standards-based teaching and educational digital libraries as innovations: Undergraduate science faculty in the adoption process

    Science.gov (United States)

    Ridgway, Judith Sulkes

    This study describes undergraduate science faculty in terms of their feelings of preparedness for and their use of standards-based teaching methods, their stages of concern related to Educational Digital Libraries (EDLs), and their adoption and diffusion of both innovations. These innovations may have a synergistic relationship that may result in enhanced adoption of both. The investigation began with a series of group meetings with life science, chemistry, physics, and geology faculty from a 2-year and a 4-year institution. Faculty were introduced to dimensions of standards-based teaching and examples of EDLs. Faculty completed the Demographics and Experience Questionnaire, the Standards-Based Teaching Instrument, and the Stages of Concern Questionnaire (SoCQ). Semi-structured interviews containing literature-based questions were conducted with one faculty member from each discipline from the 2-year and 4-year institutions. Document analyses were performed on mission/goal web-based statements for the institutions and their science departments. Triangulated data were used to construct individual faculty case studies based on four facets: background, standards-based teaching profile, EDLs profile, and rate of innovation diffusion. The individual case studies were used to perform cross-case analyses by type of institution, discipline, and locus of control. Individual case studies and cross-case analyses suggest the following conclusions: (a) faculty felt prepared to use and frequently used textbooks as a reference, (b) feelings of preparedness and frequency of use of standards-based teaching categories may be related to discipline, (c) all faculty had relatively high awareness and informational EDL concerns, and (d) faculty central to the locus of control were more likely to use methods to develop student conceptual understanding, use inquiry methods, and be agents of change. A grounded theoretical model connects study results with literature related to educational

  6. Walking the Pens: A Case Study of Secondary Agriculture Teachers’ Experiences Using a Serious Digital Game in an Introductory Animal Science Course

    2015-02-01

    Full Text Available In a world where knowledge is a click away, today’s students need information delivered in ways that meet their expectations as digital natives. Serious digital games are one way to meet the demand. This particularistic case study sought to understand agriculture teachers’ experiences using a serious digital game in an introductory animal science course. Three themes emerged from the data collected: 1 the real-world context provided by the game; 2 the game’s potential to promote students’ agricultural awareness; and 3 teachers’ positioning of the game as a secondary teaching approach. Based on these findings, it can be recommended that professional development opportunities be created for teachers to learn how to use serious digital games more effectively in other situations. Inservice workshops focused on using digital games as a primary approach to teaching secondary agricultural education curricula, especially when simulations are necessary for teaching content. Because agricultural literacy was an unintended outcome, future research should focus intentionally on the impact serious digital games have on agricultural literacy.

    As science and technology developed, the tools of humans developed from humans’hands, to mechanical and digital technologies. The tools influ-ence almost everything in the humans’world, so does vernacular. The digital vernacular could be understood as using digital technology to vernacular; the digital means technologies. It also could be understood as doing vernacular in a digital way;the digital means data and information, in other words it can be seeking truth from facts. Define digital vernacular is not only what is digital vernacular, but also about how to do the digital vernacular and what kind of attitude we should hold to-ward the digital vernacular.

  18. Performance of the Digital Science Partnership Remotely-Operated 0.5-Meter Corrected Dall-Kirkham Telescopes

    2007-12-01

    The Digital Science Partnership, a collaboration of the University of Louisville and the University of Southern Queensland, operates a pair of 0.5-meter telescopes for teaching, research, and informal education. The instruments were installed at sites near Toowoomba, Australia, and Louisville, Kentucky in 2006. The Planewave Instruments optical systems employ a unique Dall-Kirkham design incorporating a two-element corrector that demagnifies the image, flattens the focal plane, and reduces coma. These instruments have a moderately fast f/6.8 focal ratio and maintain image quality with little vignetting over a field 42 mm in diameter (0.7 degree). With a 9-micron pixel CCD such as the KAF-6303E, the image scale of 0.55 seconds of arc per pixel typically yields seeing-limited image quality at our sites. The telescopes and their enclosure are operated in a live remote observing mode through Linux-based software, including a dome-control system that uses RFID tags for absolute rotation encoding. After several months of testing and development we have examples of images and photometry from both sites that illustrate the performance of the system. We will discuss image quality, as well as practical matters such as pointing accuracy and field acquisition, auto-guiding, communication latency in large file transfer, and our experience with remote observing assisted by teleconferencing. Time-delay-integration (TDI) imaging, in which the telescope is stationary while the CCD is clocked to track in right ascension, is under study. The technique offers wide fields of view with very high signal-to-noise ratio, and can be implemented in robotically operated instruments used in monitoring, rapid-response, and educational programs. Results for conventional and TDI imaging from the dark site in Australia compared to the brighter suburban site in Kentucky show the benefits of access to dark sites through international partnerships that remote operation technology offers.

  19. Lights, camera, action research: The effects of didactic digital movie making on students' twenty-first century learning skills and science content in the middle school classroom

    Science.gov (United States)

    Ochsner, Karl

    Students are moving away from content consumption to content production. Short movies are uploaded onto video social networking sites and shared around the world. Unfortunately they usually contain little to no educational value, lack a narrative and are rarely created in the science classroom. According to new Arizona Technology standards and ISTE NET*S, along with the framework from the Partnership for 21st Century Learning Standards, our society demands students not only to learn curriculum, but to think critically, problem solve effectively, and become adept at communicating and collaborating. Didactic digital movie making in the science classroom may be one way that these twenty-first century learning skills may be implemented. An action research study using a mixed-methods approach to collect data was used to investigate if didactic moviemaking can help eighth grade students learn physical science content while incorporating 21st century learning skills of collaboration, communication, problem solving and critical thinking skills through their group production. Over a five week period, students researched lessons, wrote scripts, acted, video recorded and edited a didactic movie that contained a narrative plot to teach a science strand from the Arizona State Standards in physical science. A pretest/posttest science content test and KWL chart was given before and after the innovation to measure content learned by the students. Students then took a 21st Century Learning Skills Student Survey to measure how much they perceived that communication, collaboration, problem solving and critical thinking were taking place during the production. An open ended survey and a focus group of four students were used for qualitative analysis. Three science teachers used a project evaluation rubric to measure science content and production values from the movies. Triangulating the science content test, KWL chart, open ended questions and the project evaluation rubric, it

    2015-02-13

    An improved, reliable and powerful analytical strategy based on digitally controlled microextraction by packed sorbent (MEPS) combined with ultrahigh pressure liquid chromatography (UHPLC) was validated for the simultaneous identification and quantification of major furanic derivatives, namely 5-hydroxymethyl-2-furaldehyde (5HMF), 5-methyl-2-furaldehyde (5MF), 2-furaldehyde (2F) and 2-furyl methyl ketone (2FMK), in fortified wines. To enhance the extraction efficiency of the target furanic derivates, several influencing extraction parameters, such as number of loading cycles, nature of elution solvent and elution volume, were evaluated and optimized. In addition the ability of different MEPS sorbent materials, namely C2, C8, C18, SIL, M1, R-AX, R-CX and PGC, were also tested. The optimal analytical conditions involved loading 3×200 μL of wine samples through a C8 sorbent in a MEPS syringe placed in the semi-automatic eVolH syringe followed by elution using 200 μL MeOH:H2O (95:5, v/v). The furanic derivates separation was achieved using a CORTECS UPLC(®) C18 analytical column in an ultrafast chromatographic run (within 4 min). The method performance was assessed for dry/medium dry (D/MD) and sweet/medium sweet (S/MS) model wines in terms of selectivity, linearity, limit of detection (LOD), limit of quantitation (LOQ), accuracy, precision and matrix effect, using model wine matrix-matched calibration. Good linearity was obtained with a regression coefficient (r(2)) higher than 0.992. A good precision was attained (RSDquantification limits (LOQ) for D/MD model wines ranged from 14.9 to 431.0 ng L(-1), whereas for S/MS model wines range from 23.1 to 950.5 ng L(-1). The method also afforded satisfactory results in terms of accuracy, ranging from 74 to 97% for D/MD wines and between 84 and 99% for S/MS wines. The MEPS(C8)/UHPLC-PDA analytical strategy was successfully applied to analyze furanic derivates in 26 fortified Madeira wines from different types (D/MD, S

    2012-01-01

    An important objective of the Semi-Span Super-Sonic Transport (S4T) wind tunnel model program was the demonstration of Flutter Suppression (FS), Gust Load Alleviation (GLA), and Ride Quality Enhancement (RQE). It was critical to evaluate the stability and robustness of these control laws analytically before testing them and experimentally while testing them to ensure safety of the model and the wind tunnel. MATLAB based software was applied to evaluate the performance of closed-loop systems in terms of stability and robustness. Existing software tools were extended to use analytical representations of the S4T and the control laws to analyze and evaluate the control laws prior to testing. Lessons were learned about the complex windtunnel model and experimental testing. The open-loop flutter boundary was determined from the closed-loop systems. A MATLAB/Simulink Simulation developed under the program is available for future work to improve the CPE process. This paper is one of a series of that comprise a special session, which summarizes the S4T wind-tunnel program.

    This paper presents an open, personal, fresh approach to the future of Analytical Chemistry in the context of the deep changes Science and Technology are anticipated to experience. Its main aim is to challenge young analytical chemists because the future of our scientific discipline is in their hands. A description of not completely accurate overall conceptions of our discipline, both past and present, to be avoided is followed by a flexible, integral definition of Analytical Chemistry and its cornerstones (viz., aims and objectives, quality trade-offs, the third basic analytical reference, the information hierarchy, social responsibility, independent research, transfer of knowledge and technology, interfaces to other scientific-technical disciplines, and well-oriented education). Obsolete paradigms, and more accurate general and specific that can be expected to provide the framework for our discipline in the coming years are described. Finally, the three possible responses of analytical chemists to the proposed changes in our discipline are discussed.

  17. An Analytical Delay Model

    1999-01-01

    Delay consideration has been a majorissue in design and test of high performance digital circuits. Theassumption of input signal change occurring only when all internal nodesare stable restricts the increase of clock frequency. It is no longertrue for wave pipelining circuits. However, previous logical delaymodels are based on the assumption. In addition, the stable time of arobust delay test generally depends on the longest sensitizable pathdelay. Thus, a new delay model is desirable. This paper explores thenecessity first. Then, Boolean process to analytically describe thelogical and timing behavior of a digital circuit is reviewed. Theconcept of sensitization is redefined precisely in this paper. Based onthe new concept of sensitization, an analytical delay model isintroduced. As a result, many untestable delay faults under thelogical delay model can be tested if the output waveforms can be sampledat more time points. The longest sensitizable path length is computedfor circuit design and delay test.

    The relative length of the second (index) to the fourth (ring) finger (2D:4D) is a putative negative correlate of prenatal testosterone (T) exposure. Therefore, 2D:4D (and to a lesser extent D(r-l), the difference between 2D:4D in the right hand and in the left hand) has often been used to study effects of prenatal androgenization on human behavior and cognition. However, evidence suggests that 2D:4D may also be related to levels of circulating sex hormones in adults. This would question the validity of 2D:4D as a means of studying the effects of prenatal sex hormones. Here we present new data from two non-clinical samples (64 women and 102 men) regarding the relationships of 2D:4D and D(r-l) with circulating sex hormone levels. We then present a meta-analytic review of all the present evidence regarding this issue. The results suggest that, in the normal population, 2D:4D and D(r-l) are not associated with adult sex hormone levels. The findings from this current study add to the growing body of evidence demonstrating that 2D:4D is a suitable tool to study the effects of prenatal androgenization on human behavior and cognition.

    Full Text Available Digital systems pervade classic STS sites of interest, from connecting laboratories to mediating lay-expert divides. But STS has so far been reticent to build the theoretical and analytical perspectives necessary for embracing digital systems as an important element of contemporary fieldwork, research, and practice. This paper charts a course for bringing STS concepts to bear on digital systems and vice versa, bringing our lingering concern with questions from the sociology of knowledge to bear on digitally-enacted and mediated scientific and technical practices. It shows how we can eschew the language of technological determinism inherent to discussion about digital systems outside of STS, asking instead questions germane to STS theory and practice such as the configuration of such systems to include and exclude, the epistemic entanglements of using digital tools in research practice, and the potential to build new systems that suggest alternative arrangements.

    Familiarity with the structure and composition of normal tissue and an understanding of the changes that occur during disease is pivotal to the study of the human body. For decades, microscope slides have been central to teaching pathology in medical courses and related subjects at the University of Copenhagen. Students had to learn how to use a microscope and envisage three-dimensional processes that occur in the body from two-dimensional glass slides. Here, we describe how a PathXL virtual microscopy system for teaching pathology and histology at the Faculty has recently been implemented, from an administrative, an economic, and a teaching perspective. This fully automatic digital microscopy system has been received positively by both teachers and students, and a decision was made to convert all courses involving microscopy to the virtual microscopy format. As a result, conventional analog microscopy will be phased out from the fall of 2016.

    Digital Earth Watch (DEW) involves individuals, schools, organizations and communities in a systematic monitoring project of their local environment, especially vegetation health. The DEW Picture Post network offers people the means to make and share their own observations. A Picture Post is an easy-to-use and inexpensive platform for repeatedly taking digital photographs as a standardized set of images of the entire 360° landscape, which then can be shared over the Internet on the Picture Post website. This simple concept has the potential to create a wealth of information and data on changing environmental conditions, which is important for a society grappling with the effects of climate change. As a web-based program, it is critical to bring in new participants and to convey technical, scientific, and participant information with little or no human interaction. Once they get going, it is also important to keep participants engaged by getting their feedback as well as by sharing their experiences. This presentation will demonstrate our use of video to enhance the program, in particular the power of video for teaching skills needed to start up and contribute to a picture post, to convey findings and other scientific information collected at picture posts, and to engage participants and the community in an ongoing effort in monitoring and understanding their local environment and changing conditions. A DEW video library is being developed by a collaborative effort led by the University of New Hampshire with the University of Southern Maine, and Concord Academy.

  9. Analytic Materials

    CERN Document Server

    Milton, Graeme W

    2016-01-01

    The theory of inhomogeneous analytic materials is developed. These are materials where the coefficients entering the equations involve analytic functions. Three types of analytic materials are identified. The first two types involve an integer $p$. If $p$ takes its maximum value then we have a complete analytic material. Otherwise it is incomplete analytic material of rank $p$. For two-dimensional materials further progress can be made in the identification of analytic materials by using the well-known fact that a $90^\\circ$ rotation applied to a divergence free field in a simply connected domain yields a curl-free field, and this can then be expressed as the gradient of a potential. Other exact results for the fields in inhomogeneous media are reviewed. Also reviewed is the subject of metamaterials, as these materials provide a way of realizing desirable coefficients in the equations.

    ABSTRACT:Ionic liquids (ILs) are a class of organic molten salt with melting point below 100 °C. They are usually composed of asymmetrical organic cations and anions. Their properties can be readily tuned by changing the composition of cation or anion, so they are also called “designer solvents”. Due to their unique physicochemical properties, they were widely used in organic chemistry and analytic chemistry. In this paper, the recent research and application of ILs in the field of extraction pretreatment, chromatography, capillary electrophoresis, electroanalysis and spectrophotometry were reviewed from the type, structure and properties of ILs. The advantages and disadvantages of different ionic liquids in various fields were compared from the perspective of applications mechanism, which can be instructive for the application and development of ionic liquids in future. The prospects of ionic liquids were also discussed and forecasted. The results suggested that ionic liquids showed more potential in the fields of chromatography and capillary electrophoresis. Moreover, designing and developing new types of ionic liquids and exploring the mechanism of the extraction and separation will promote the development of ionic liquids in the field of analytic sciences. Ionic liquids will be widely used in complex sample analysis and trace detection in the near future.%离子液体是一类熔点低于100℃的有机熔融盐,通常由不对称的有机阳离子和阴离子组成,其性质可以通过改变阴阳离子组成灵活调节,被称为“设计者的溶剂”。由于其特殊的物理化学性质,离子液体在有机化学和分析化学等领域得到广泛应用,本文主要从离子液体类型、结构和性能等角度综述其在萃取前处理、色谱、毛细管电泳及电分析、光谱等领域中的研究进展,从应用机理角度对比不同离子液体在各领域应用中的优缺点,这对离子液体目前的应用状况

    The Bundlab software has been developed mainly for academic and research application. This work can be treated as a kind of a report describing the current state of the development of this computer program, focusing especially on the analytical solutions. Firstly, the overall characteristics of the software are provided. Then the description of the image orientation procedure starting from the relative orientation is addressed. The applied solution is based on the coplanarity equation parametrized with the essential matrix. The problem is reformulated in order to solve it using methods of algebraic geometry. The solution is followed by the optimization involving the least square criterion. The formation of the image block from the oriented models as well as the absolute orientation procedure were implemented using the Horn approach as a base algorithm. The second part of the paper is devoted to the tools and methods applied in the stereo digitization module. The solutions that support the user and improve the accuracy are given. Within the paper a few exemplary applications and products are mentioned. The work finishes with the concepts of development and improvements of existing functions.

    Big Data is everywhere – from Computational Science to Digital Humanities, from Web Analytics to traditional libraries. While there do exist significant challenges in other areas, for many the biggest issue of all is a digital libraries one – How do we preserve big data collections? How do we provide access to big data collections? What new questions can we pose against our big data collections? These are all digital libraries questions. How can we, the digital libraries community, stand up in the face of these challenges and inform collection builders, curators, and interface developers how to best solve their challenges? What assumptions have we been working under that no longer hold in light of Big Data? These are some of the timely questions we hope to address at JCDL 2015.

  11. Croatian Analytical Terminology

    Directory of Open Access Journals (Sweden)

    Kastelan-Macan; M.

    2008-04-01

    Full Text Available Results of analytical research are necessary in all human activities. They are inevitable in making decisions in the environmental chemistry, agriculture, forestry, veterinary medicine, pharmaceutical industry, and biochemistry. Without analytical measurements the quality of materials and products cannot be assessed, so that analytical chemistry is an essential part of technical sciences and disciplines.The language of Croatian science, and analytical chemistry within it, was one of the goals of our predecessors. Due to the political situation, they did not succeed entirely, but for the scientists in independent Croatia this is a duty, because language is one of the most important features of the Croatian identity. The awareness of the need to introduce Croatian terminology was systematically developed in the second half of the 19th century, along with the founding of scientific societies and the wish of scientists to write their scientific works in Croatian, so that the results of their research may be applied in economy. Many authors of textbooks from the 19th and the first half of the 20th century contributed to Croatian analytical terminology (F. Rački, B. Šulek, P. Žulić, G. Pexidr, J. Domac, G. Janeček , F. Bubanović, V. Njegovan and others. M. DeŢelić published the first systematic chemical terminology in 1940, adjusted to the IUPAC recommendations.

  12. Doing social media analytics

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available In the few years since the advent of ‘Big Data’ research, social media analytics has begun to accumulate studies drawing on social media as a resource and tool for research work. Yet, there has been relatively little attention paid to the development of methodologies for handling this kind of data. The few works that exist in this area often reflect upon the implications of ‘grand’ social science methodological concepts for new social media research (i.e. they focus on general issues such as sampling, data validity, ethics, etc.. By contrast, we advance an abductively oriented methodological suite designed to explore the construction of phenomena played out through social media. To do this, we use a software tool – Chorus – to illustrate a visual analytic approach to data. Informed by visual analytic principles, we posit a two-by-two methodological model of social media analytics, combining two data collection strategies with two analytic modes. We go on to demonstrate each of these four approaches ‘in action’, to help clarify how and why they might be used to address various research questions.

    Full Text Available This paper explores emerging practices in research data management in the arts, humanities and social sciences (AHSS. It will do so vis-à-vis current citation conventions and impact measurement for research in AHSS. Case study findings on research data inventoried at Goldsmiths’, University of London will be presented. Goldsmiths is a UK research-intensive higher education institution which specialises in arts, humanities and social science research. The paper’s aim is to raise awareness of the subject-specific needs of AHSS scholars to help inform the design of future digital tools for impact analysis in AHSS. Firstly, I shall explore the definition of research data and how it is currently understood by AHSS researchers. I will show why many researchers choose not to engage with digital dissemination techniques and ORCID. This discussion must necessarily include the idea that practice-based and applied AHSS research are processes which are not easily captured in numerical ‘sets’ and cannot be labelled electronically without giving careful consideration to what a group or data item ‘represents’ as part of the academic enquiry, and therefore how it should be cited and analysed as part of any impact assessment. Then, the paper will explore: the role of the monograph and arts catalogue in AHSS scholarship; how citation practices and digital impact measurement in AHSS currently operate in relation to authorship and how digital identifiers may hypothetically impact on metrics, intellectual property (IP, copyright and research integrity issues in AHSS. I will also show that, if we are to be truly interdisciplinary, as research funders and strategic thinkers say we should, it is necessary to revise the way we think about digital research dissemination. This will involve breaking down the boundaries between AHSS and other types of research.

  1. Supramolecular analytical chemistry.

    Science.gov (United States)

    Anslyn, Eric V

    2007-02-02

    A large fraction of the field of supramolecular chemistry has focused in previous decades upon the study and use of synthetic receptors as a means of mimicking natural receptors. Recently, the demand for synthetic receptors is rapidly increasing within the analytical sciences. These classes of receptors are finding uses in simple indicator chemistry, cellular imaging, and enantiomeric excess analysis, while also being involved in various truly practical assays of bodily fluids. Moreover, one of the most promising areas for the use of synthetic receptors is in the arena of differential sensing. Although many synthetic receptors have been shown to yield exquisite selectivities, in general, this class of receptor suffers from cross-reactivities. Yet, cross-reactivity is an attribute that is crucial to the success of differential sensing schemes. Therefore, both selective and nonselective synthetic receptors are finding uses in analytical applications. Hence, a field of chemistry that herein is entitled "Supramolecular Analytical Chemistry" is emerging, and is predicted to undergo increasingly rapid growth in the near future.

    Directory of Open Access Journals (Sweden)

    Katherine Fogelberg

    2016-07-01

    Full Text Available Detailed here is the creation and application of a replicable method bricolage that brings together Discourse Analysis, discourse analysis, and the theory of reasoned action to examine attitudes and beliefs of university science professors toward the discipline of education. This method used a two-phase method for analysis. The first phase looked for phrases that could be defined as either an attitude or a belief based on definitions taken from the social psychology and communication studies literature. The second phase interpreted the overall data to explore the influences on the formation of the attitudes and beliefs as well as to support or refute the findings from Phase 1. The need for a replicable Discourse Analysis method is apparent in the education literature, as is a solid definition of what constitutes an attitude or a belief. The method outlined here provides good definitions for attitudes and beliefs, a method for extracting both constructs from the data, and incorporates an internal crystallization process for looking at and comparing emergent themes from both phases of analysis.

  6. Digital Information and Value

    Directory of Open Access Journals (Sweden)

    Paul Walton

    2015-11-01

    Full Text Available Digital information changes the ways in which people and organisations interact. This paper examines the nature of this change in the context of the author’s Model for Information (MfI. It investigates the relationship between outcomes and value, selection processes and some attributes of information and explores how this relationship changes in the move from analogue to digital information. Selection processes shape the evolution of information ecosystems in which conventions are established for the ways in which information is used. The conventions determine norms for information friction and information quality as well as the sources of information and channels used. Digital information reduces information friction, often dramatically, and changes information quality. The increasing use of analytics in business increasingly delivers predictive or prescriptive digital information. These changes are happening faster than information ecosystem conventions can change. The relationships established in the paper enable an analysis of, and guide changes to, these conventions enabling a more effective use of digital information.

  10. USGS42 and USGS43: Human-hair stable hydrogen and oxygen isotopic reference materials and analytical methods for forensic science and implications for published measurement results

    Coplen, T.B.; Qi, H.

    2012-01-01

    Because there are no internationally distributed stable hydrogen and oxygen isotopic reference materials of human hair, the U.S. Geological Survey (USGS) has prepared two such materials, USGS42 and USGS43. These reference materials span values commonly encountered in human hair stable isotope analysis and are isotopically homogeneous at sample sizes larger than 0.2 mg. USGS42 and USGS43 human-hair isotopic reference materials are intended for calibration of δ(2)H and δ(18)O measurements of unknown human hair by quantifying (1) drift with time, (2) mass-dependent isotopic fractionation, and (3) isotope-ratio-scale contraction. While they are intended for measurements of the stable isotopes of hydrogen and oxygen, they also are suitable for measurements of the stable isotopes of carbon, nitrogen, and sulfur in human and mammalian hair. Preliminary isotopic compositions of the non-exchangeable fractions of these materials are USGS42(Tibetan hair)δ(2)H(VSMOW-SLAP) = -78.5 ± 2.3‰ (n = 62) and δ(18)O(VSMOW-SLAP) = +8.56 ± 0.10‰ (n = 18) USGS42(Indian hair)δ(2)H(VSMOW-SLAP) = -50.3 ± 2.8‰ (n = 64) and δ(18)O(VSMOW-SLAP) = +14.11 ± 0.10‰ (n = 18). Using recommended analytical protocols presented herein for δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) measurements, the least squares fit regression of 11 human hair reference materials is δ(2)H(VSMOW-SLAP) = 6.085δ(2)O(VSMOW-SLAP) - 136.0‰ with an R-square value of 0.95. The δ(2)H difference between the calibrated results of human hair in this investigation and a commonly accepted human-hair relationship is a remarkable 34‰. It is critical that readers pay attention to the δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) of isotopic reference materials in publications, and they need to adjust the δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) measurement results of human hair in previous publications, as needed, to ensure all results on are on the same scales.

    Because there are no internationally distributed stable hydrogen and oxygen isotopic reference materials of human hair, the U.S. Geological Survey (USGS) has prepared two such materials, USGS42 and USGS43. These reference materials span values commonly encountered in human hair stable isotope analysis and are isotopically homogeneous at sample sizes larger than 0.2 mg. USGS42 and USGS43 human-hair isotopic reference materials are intended for calibration of δ(2)H and δ(18)O measurements of unknown human hair by quantifying (1) drift with time, (2) mass-dependent isotopic fractionation, and (3) isotope-ratio-scale contraction. While they are intended for measurements of the stable isotopes of hydrogen and oxygen, they also are suitable for measurements of the stable isotopes of carbon, nitrogen, and sulfur in human and mammalian hair. Preliminary isotopic compositions of the non-exchangeable fractions of these materials are USGS42(Tibetan hair)δ(2)H(VSMOW-SLAP) = -78.5 ± 2.3‰ (n = 62) and δ(18)O(VSMOW-SLAP) = +8.56 ± 0.10‰ (n = 18) USGS42(Indian hair)δ(2)H(VSMOW-SLAP) = -50.3 ± 2.8‰ (n = 64) and δ(18)O(VSMOW-SLAP) = +14.11 ± 0.10‰ (n = 18). Using recommended analytical protocols presented herein for δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) measurements, the least squares fit regression of 11 human hair reference materials is δ(2)H(VSMOW-SLAP) = 6.085δ(2)O(VSMOW-SLAP) - 136.0‰ with an R-square value of 0.95. The δ(2)H difference between the calibrated results of human hair in this investigation and a commonly accepted human-hair relationship is a remarkable 34‰. It is critical that readers pay attention to the δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) of isotopic reference materials in publications, and they need to adjust the δ(2)H(VSMOW-SLAP) and δ(18)O(VSMOW-SLAP) measurement results of human hair in previous publications, as needed, to ensure all results on are on the same scales.

    Sobotka, Werner K.

    1997-02-01

    Digital printing is described as a tool to replace conventional printing machines completely. Still this goal was not reached until now with any of the digital printing technologies to be described in the paper. Productivity and costs are still the main parameters and are not really solved until now. Quality in digital printing is no problem anymore. Definition of digital printing is to transfer digital datas directly on the paper surface. This step can be carried out directly or with the use of an intermediate image carrier. Keywords in digital printing are: computer- to-press; erasable image carrier; image carrier with memory. Digital printing is also the logical development of the new digital area as it is pointed out in Nicholas Negropotes book 'Being Digital' and also the answer to networking and Internet technologies. Creating images text and color in one country and publishing the datas in another country or continent is the main advantage. Printing on demand another big advantage and last but not least personalization the last big advantage. Costs and being able to coop with this new world of prepress technology is the biggest disadvantage. Therefore the very optimistic growth rates for the next few years are really nonexistent. The development of complete new markets is too slow and the replacing of old markets is too small.

    Climate science is a big data domain that is experiencing unprecedented growth. In our efforts to address the big data challenges of climate science, we are moving toward a notion of Climate Analytics-as-a-Service (CAaaS). CAaaS combines high-performance computing and data-proximal analytics with scalable data management, cloud computing virtualization, the notion of adaptive analytics, and a domain-harmonized API to improve the accessibility and usability of large collections of climate data. MERRA Analytic Services (MERRA/AS) provides an example of CAaaS. MERRA/AS enables MapReduce analytics over NASA's Modern-Era Retrospective Analysis for Research and Applications (MERRA) data collection. The MERRA reanalysis integrates observational data with numerical models to produce a global temporally and spatially consistent synthesis of key climate variables. The effectiveness of MERRA/AS has been demonstrated in several applications. In our experience, CAaaS is providing the agility required to meet our customers' increasing and changing data management and data analysis needs.

    Full Text Available Digital publishing is causing a real paradigm shift for research institutions and publishers, as well as for libraries. As a consequence these institutions have to develop new policies, new business models and new infrastructures and techniques. A major problem is that, at the same rate at which our world is becoming digital, the digital information is threatened. New types of hardware, computer applications and file formats supersede each other, making our recorded digital information inaccessible in the long-term. In the past years libraries and archives have undertaken several actions and studies on digital preservation issues. For instance the Koninklijke Bibliotheek (KB has jointly with IBM developed a standard-based deposit system: Digital Information Archiving System ( DIAS. Using DIAS the KB realised in 2002 an electronic deposit (the e-Depot and signed archiving agreements with major science publishers for permanent keeping of their digital materials. In this paper I will discuss the fully operational e-Depot at the KB. I will focus on the data flow of processing the digital publications, and I will address the issue of digital preservation in detail.

    In parallel with the progress of the practical use of satellite broadcasting and Hi-Vision or high-definition television technologies, research activities are also in progress to replace the conventional analog broadcasting services with a digital version. What we call 'digitalization' is not a mere technical matter but an important subject which will help promote multichannel or multimedia applications and, accordingly, can change the old concept of mass media, such as television or radio. NHK Science and Technical Research Laboratories has promoted studies of digital bandwidth compression, transmission, and application techniques. The following topics are covered: the trend of digital broadcasting; features of Integrated Services Digital Broadcasting (ISDB); compression encoding and transmission; transmission bit rate in 12 GHz band; number of digital TV transmission channels; multichannel pulse code modulation (PCM) audio broadcasting system via communication satellite; digital Hi-Vision broadcasting; and development of digital audio broadcasting (DAB) for mobile reception in Japan.

    This action research project investigated fourth grade students¡¦ motivation to learn science using a digital science techbook. Participants in the study included 29 fourth grade students in two different classrooms. One classroom of 16 students used a digital science techbook to learn science while the other classroom of 13 students used a traditional paper science textbook to learn science. Students in both classrooms answered five sets of questions regarding their experience using a digital science techbook and a paper science techbook to understand science, find science information, solve science problems, learn science, and assess learning science was fun. Results were compiled and coded based on positive and negative responses to conditions. A chi-square was used to analyze the ordinal data. Overall differences between techbooks vs. textbook were significant, X2 (1, N = 29) = 23.84, p = .000, justifying further examination of individual survey items. Three items had statistically significant difference for finding science information, solving science problems, and learning science. A gender difference was also found in one item. Females preferred to use paper science textbooks to understand science, while males preferred digital techbooks to learn science. The fourth graders in this study indicated that digital techbooks were a powerful learning tool for increasing interest, excitement and learning science. Even though students reported paper science textbooks as easy to use, they found using digital science techbooks a far more appealing way to learn science.

    Addressing grand environmental science challenges requires unprecedented access to easily understood data that cross the breadth of temporal, spatial, and thematic scales. From a scientist's perspective, the big challenges lie in discovering the relevant data, dealing with extreme data heterogeneity, large data volumes, and converting data to information and knowledge. Historical linkages between derived products, i.e. Publications, and associated datasets has not existed in the earth science community. The USGS Core Science Analytics and Synthesis, in collaboration with DOE's Oak Ridge National Laboratory (ORNL) Mercury Consortium (funded by NASA, USGS and DOE), established a Digital Object Identifier (DOI) service for USGS data, metadata, and other media. This service is offered in partnership through the University of California Digital Library EZID service. USGS scientists, data managers, and other professionals can generate globally unique, persistent and resolvable identifiers for any kind of digital objects. Additional efforts to assign DOIs to historical data and publications have also been underway. These DOI identifiers are being used to cite data in journal articles, web-accessible datasets, and other media for distribution, integration, and in support of improved data management practices. The session will discuss the current DOI efforts within USGS, including a discussion on adoption, challenges, and future efforts necessary to improve access, reuse, sharing, and discoverability of USGS data and information.

    Full Text Available The huge amount of multimedia contents available on the World-Wide-Web is beginning to raise the question of their protection. Digital watermarking is a technique which can serve various purposes, including intellectual property protection, authentication and integrity verification, as well as visible or invisible content labelling of multimedia content. Due to the diversity of digital watermarking applicability, there are many different techniques, which can be categorised according to different criteria. A digital watermark can be categorised as visible or invisible and as robust or fragile. In contrast to the visible watermark where a visible pattern or image is embedded into the original image, the invisible watermark does not change the visual appearance of the image. The existence of such a watermark can be determined only through a watermark ex¬traction or detection algorithm. The robust watermark is used for copyright protection, while the fragile watermark is designed for authentication and integrity verification of multimedia content. A watermark must be detectable or extractable to be useful. In some watermarking schemes, a watermark can be extracted in its exact form, in other cases, we can detect only whether a specific given watermarking signal is present in an image. Digital libraries, through which cultural institutions will make multimedia contents available, should support a wide range of service models for intellectual property protection, where digital watermarking may play an important role.

  5. Learning the Rules of the Game: The Nature of Game and Classroom Supports When Using a Concept-Integrated Digital Physics Game in the Middle School Science Classroom

    Science.gov (United States)

    Stewart, Phillip Michael, Jr.

    Games in science education is emerging as a popular topic of scholarly inquiry. The National Research Council recently published a report detailing a research agenda for games and science education entitled Learning Science Through Computer Games and Simulations (2011). The report recommends moving beyond typical proof-of-concept studies into more exploratory and theoretically-based work to determine how best to integrate games into K-12 classrooms for learning , as well as how scaffolds from within the game and from outside the game (from peers and teachers) support the learning of applicable science. This study uses a mixed-methods, quasi-experimental design with an 8th grade class at an independent school in southern Connecticut to answer the following questions: 1. What is the nature of the supports for science content learning provided by the game, the peer, and the teacher, when the game is used in a classroom setting? 2. How do the learning gains in the peer support condition compare to the solo play condition, both qualitatively and quantitatively? The concept-integrated physics game SURGE (Scaffolding Understanding through Redesigning Games for Education) was selected for this study, as it was developed with an ear towards specific learning theories and prior work on student understandings of impulse, force, and vectors. Stimulated recall interviews and video observations served as the primary sources and major patterns emerged through the triangulation of data sources and qualitative analysis in the software QSR NVivo 9. The first pattern which emerged indicated that scaffolding from within the game and outside the game requires a pause in game action to be effective, unless that scaffolding is directly useful to the player in the moment of action. The second major pattern indicated that both amount and type of prior gaming experience has somewhat complex effects on both the uses of supports and learning outcomes. In general, a high correlation was found

    2011-12-01

    Dozens of web-based initiatives allow citizens to provide information to programs that monitor the health of our environment. A concerned citizen can participate on-line as a weather "spotter", provide important phenological information to national databases, update bird counts in the area, or record the freezing of ponds, and much more. Many of these programs are developing mobile apps as companion tools to their web sites. Our group was involved in the development of one such companion app as an adjunct to the Picture Post project web site. Digital Earth Watch (DEW) and the Picture Post network support environmental monitoring through repeat digital photography and satellite imagery. A Picture Post is an eight-sided platform on a stand-alone post for taking a panoramic series of photographs. By taking pictures on a regular basis at Picture Post sites and by sharing these pictures on the program's web site (housed at the University of New Hampshire), citizen scientists are creating a photographic library of change-over-time in their local area and contributing to national monitoring programs. Our DEW Android application simplifies participation by allowing users to upload pictures instantly from their smart phone. The app also removes the constraint of the physical picture post, by allowing users to create a virtual post anywhere in the world. Posts have been set up to monitor trails, forests, water, wetlands, gardens and landscapes. The app uses the phone's GPS to position the virtual post in its geographic location and guides the user through the orientations thanks to the internal accelerometers and compass. To aid in the before-and-after comparison of images taken from the same orientation, the DEW app displays an "onionskin" of the prior image overlayed onto the camera viewfinder. With the transparent onionskin as a guide, the user can align the images more accurately, thus allowing differences between pictures to be detectable and measurable. The app

    Scientific digital libraries serve complex and evolving research communities. Justifications for the development of scientific digital libraries include the desire to preserve science data and the promises of information interconnectedness, correlative science, and system interoperability. Shared ontologies are fundamental to fulfilling these promises. We present a tool framework, some informal principles, and several case studies where shared ontologies are used to guide the implementation of scientific digital libraries. The tool framework, based on an ontology modeling tool, was configured to develop, manage, and keep shared ontologies relevant within changing domains and to promote the interoperability, interconnectedness, and correlation desired by scientists.

    Keall, B. S.; Koers, H.

    2013-12-01

    Thanks to decades of technological advances to improve the collection, organization, storage, and sharing of data, experimental research data has become an increasingly important element of the research process. And one can only expect that the relevance of research data will continue to grow, given the recent push from funding bodies to make research data better available, the emergence of trusted, domain-specific data repositories, and the support from journal publishers. Elsevier is excited by the prospect of accelerating the pace of research by creating proper solutions for research data, including bidirectional links between articles and data to enable discovery and proper re-use. Connecting articles and data is an integral part of Elsevier's 'Article of the Future', an ongoing program to improve the article format to meet the needs of modern-day researchers. As part of this effort, we have set up bi-directional linking between online articles and data repositories so that researchers can easily find the data that is relevant for a paper and vice versa. Recently, we have set up such links with some of the leading data repositories in Earth Sciences, including the British Geological Survey, IEDA's Marine Geoscience Data System, and the Oak Ridge National Laboratory DAAC. Building on these links, Elsevier has also developed a number of data integration and visualization tools, such as our long-standing collaboration with PANGAEA. Another dimension of the Article of the Future is to provide authors with the capabilities to embed digital research output to their publication, thus breaking away from the limitations of the traditional ink-on-paper format. Supported digital content types include interactive (Google) maps, videos, and 3D models. Recently, we have also published a Special Issue with Executable Papers that combines the narrative of the article with data and code elements, all connected in such a way that researchers can perform computations while

    The ability to break up a volume of fluid into smaller pieces that are confined or separated to prevent molecular communication/transport is a key capability intrinsic to microfluidic systems. This capability has been used to develop or implement digital versions of traditional molecular analysis assays, including digital PCR and digital immunoassays/ELISA. In these digital versions, the concentration of the target analyte is in a range such that, when sampled into smaller fluid volumes, either a single molecule or no molecule may be present. Subsequent amplification is sensitive enough to obtain a digital readout of the presence of these target molecules. Advantages of such approaches that are claimed include quantification without calibration and robustness to variations in reaction conditions or times because the digital readout is less sensitive to absolute signal intensity levels. Weaknesses of digital approaches include a lower dynamic range of concentrations over which the assay is sensitive, which depends on the total volume that can be analyzed. We highlight recent efforts to expand the dynamic range of digital assays based on exploiting reaction/diffusion phenomena. A side-by-side study that evaluates the strengths of digital assays reveals that the majority of these claims are supported, with specific caveats. Finally, we highlight approaches to apply digital assays to analyze new types of reactions, including the active transport of protons across membranes by ATPases at the single protein level - perhaps opening up new biophysical understanding and screening opportunities, similar to widely deployed single-molecule ion channel analysis.

  10. Physical Analytics: An emerging field with real-world applications and impact

    2015-03-01

    In the past most information on the internet has been originated by humans or computers. However with the emergence of cyber-physical systems, vast amount of data is now being created by sensors from devices, machines etc digitizing the physical world. While cyber-physical systems are subject to active research around the world, the vast amount of actual data generated from the physical world has attracted so far little attention from the engineering and physics community. In this presentation we use examples to highlight the opportunities in this new subject of ``Physical Analytics'' for highly inter-disciplinary research (including physics, engineering and computer science), which aims understanding real-world physical systems by leveraging cyber-physical technologies. More specifically, the convergence of the physical world with the digital domain allows applying physical principles to everyday problems in a much more effective and informed way than what was possible in the past. Very much like traditional applied physics and engineering has made enormous advances and changed our lives by making detailed measurements to understand the physics of an engineered device, we can now apply the same rigor and principles to understand large-scale physical systems. In the talk we first present a set of ``configurable'' enabling technologies for Physical Analytics including ultralow power sensing and communication technologies, physical big data management technologies, numerical modeling for physical systems, machine learning based physical model blending, and physical analytics based automation and control. Then we discuss in detail several concrete applications of Physical Analytics ranging from energy management in buildings and data centers, environmental sensing and controls, precision agriculture to renewable energy forecasting and management.

    Kaufman, H.

    1976-01-01

    A design study of adaptive control logic suitable for implementation in modern airborne digital flight computers was conducted. Both explicit controllers which directly utilize parameter identification and implicit controllers which do not require identification were considered. Extensive analytical and simulation efforts resulted in the recommendation of two explicit digital adaptive flight controllers. Interface weighted least squares estimation procedures with control logic were developed using either optimal regulator theory or with control logic based upon single stage performance indices.

    Digital social analytics is a subset of Big Data methods that is used to understand the social environment in which people and organizations have to act. This paper presents an analysis of eight projects that are experimenting with the use of these methods for various purposes. It shows that two...... specific technological features influence the work with such methods in all the cases. The first concerns the need to distribute choices about the structure of data to third-party actors and the second concerns the need to balance machine intelligence and human intuition when automating the analysis...... leaders interact with the features of the data environment. It thereby also shows how digital social analytics come to have different affordances for different projects....

    Gjonaj, Bergin; Johnson, Patrick M; Mosk, Allard P; Kuipers, Kobus; Lagendijk, Ad

    2010-01-01

    The field of plasmonics offers a route to control light fields with metallic nanostructures through the excitation of Surface Plasmon Polaritons (SPPs). These surface waves, bound to a metal dielectric interface, tightly confine electromagnetic energy. Active control over SPPs has potential for applications in sensing, photovoltaics, quantum communication, nano circuitry, metamaterials and super-resolution microscopy. We achieve here a new level of control of plasmonic fields using a digital spatial light modulator. Optimizing the plasmonic phases via feedback we focus SPPs at a freely pre-chosen point on the surface of a nanohole array with high resolution. Digital addressing and scanning of SPPs without mechanical motion will enable novel interdisciplinary applications of advanced plasmonic devices in cell microscopy, optical data storage and sensing.

    1999-12-01

    This article is an electronic publication in Spectrochimica Acta Electronica (SAE), a section of Spectrochimica Acta Part B (SAB). The hardcopy text is accompanied by an electronic archive, stored on the CD-ROM accompanying this issue. The archive contains video clips. The main article discusses the scientific aspects of the subject and explains the purpose of the video files. Short, 15-30 s, digital video clips are easily controllable at the computer keyboard, which gives a speaker the ability to show fine details through the use of slow motion. Also, they are easily accessed from the computer hard drive for rapid extemporaneous presentation. In addition, they are easily transferred to the Internet for dissemination. From a pedagogical point of view, the act of making a video clip by a student allows for development of powers of observation, while the availability of the technology to make digital video clips gives a teacher the flexibility to demonstrate scientific concepts that would otherwise have to be done as 'live' demonstrations, with all the likely attendant misadventures. Our experience with digital video clips has been through their use in computer-based presentations by undergraduate and graduate students in analytical chemistry classes, and by high school and middle school teachers and their students in a variety of science and non-science classes. In physics teaching laboratories, we have used the hardware to capture digital video clips of dynamic processes, such as projectiles and pendulums, for later mathematical analysis.

However, this approach is evidently improper and misleading. Therefore, the position of modern analytical chemistry among sciences and in the contemporary world is discussed. Its interdisciplinary character and the necessity of the collaboration between analytical chemists and other experts in order to effectively solve the actual problems of the human society and the environment are emphasized. The importance of the analytical method validation in order to obtain the accurate and precise results is highlighted. The invalid results are not only useless; they can often be even fatal (e.g., in clinical laboratories). The curriculum of analytical chemistry at schools and universities is discussed. It is referred to be much broader than traditional equilibrium chemistry coupled with a simple description of individual analytical methods. Actually, the schooling of analytical chemistry should closely connect theory and practice.

    Full Text Available Digital Storytelling (DST is a powerful tool for teaching complex concepts. DSTs are typically used in the humanities but several papers have shown that they are also a wonderful tool for the sciences because they are more involving, contextualized and can easily lead to deeper understanding. In the classical use of DST the story is thecontent, while the digital medium is the way of telling it. Our approach is slightly different: the story is not the content but a glue for the main contents, while the digital medium remains the way to tell the story. We propose the use of DST as a means to teach surgeons the basics of robotic surgery, by using a story that should be involving forthem, i.e. a surgical operation, within which we will illustrate specific concepts onrobotics in surgery.

    Visual analytics is the science of marrying interactive visualizations and analytic algorithms to support exploratory knowledge discovery in large datasets. We argue for a shift from a ‘human in the loop’ philosophy for visual analytics to a ‘human is the loop’ viewpoint, where the focus is on recognizing analysts’ work processes, and seamlessly fitting analytics into that existing interactive process. We survey a range of projects that provide visual analytic support contextually in the sensemaking loop, and outline a research agenda along with future challenges.

    Full Text Available The question of explosion and digital preservation issues are totally in vogue today. In this context, the aim of this study is to analyze bibliographically the typeset production and published the “RDBCI: Revista Digital de Biblioteconomia e Ciência da Informação” in these its thirteen years of existence, in order to disclose the analysis of published scientific production, featuring the themes of articles and the most representative authors, contributing to the community area in question as well as enhance the importance of the magazine to the field of Library and Information Science. The journal is entirely digital, born and incubated on free platform OJS/SEER, provided by IBICT since 2004. Moreover, in these years of experience the magazine is effective information vehicle of the area and its existence confirms that electronic publications born in this format, survive in the digital world. From 2013, the RDBCI began to integrate Cariniana Network (IBICT, digitally preserving your entire collection through the LOCKSS software, and other institutions aggregated to the network, and in March 2016 began to integrate The Keepers Registry, making If the first Brazilian publication to be part of this international digital preservation network. The methodology adopted was through a survey of articles published from 2003 to 2016, collecting data such as access numbers, downloads, and other statistical and qualitative indicators, making use of tools such as Google Analytics, Altmetrics, Index h and alternative metrics as well as databases, directories, portals and indexes where the journal is indexed. We believe the result of this work serves as a qualitative analysis model for other periodicals and promotes growth of more national and international scientific publications with open access.

    Some of the factors that can contribute to the success of collaborative adaptive management--such as social learning, open communication, and trust--are built upon a foundation of the open exchange of information about science and management between participants and the public. Despite the importance of information transparency, the use and flow of information in collaborative adaptive management has not been characterized in detail in the literature, and currently there exist opportunities to develop strategies for increasing the exchange of information, as well as to track information flow in such contexts. As digital information channels and networks have been increased over the last decade, powerful new information monitoring tools have also been evolved allowing for the complete characterization of information products through their production, transport, use, and monitoring. This study uses these tools to investigate the use of various science and management information products in a case study--the Sierra Nevada Adaptive Management Project--using a mixed method (citation analysis, web analytics, and content analysis) research approach borrowed from the information processing and management field. The results from our case study show that information technologies greatly facilitate the flow and use of digital information, leading to multiparty collaborations such as knowledge transfer and public participation in science research. We conclude with recommendations for expanding information exchange in collaborative adaptive management by taking advantage of available information technologies and networks.

  2. Physical computation and cognitive science

    CERN Document Server

    Fresco, Nir

    2014-01-01

    This book presents a study of digital computation in contemporary cognitive science. Digital computation is a highly ambiguous concept, as there is no common core definition for it in cognitive science. Since this concept plays a central role in cognitive theory, an adequate cognitive explanation requires an explicit account of digital computation. More specifically, it requires an account of how digital computation is implemented in physical systems. The main challenge is to deliver an account encompassing the multiple types of existing models of computation without ending up in pancomputationalism, that is, the view that every physical system is a digital computing system. This book shows that only two accounts, among the ones examined by the author, are adequate for explaining physical computation. One of them is the instructional information processing account, which is developed here for the first time.   “This book provides a thorough and timely analysis of differing accounts of computation while adv...

    The High Energy Accelerator Research Organization KEK digital accelerator (KEK-DA) is a renovation of the KEK 500 MeV booster proton synchrotron, which was shut down in 2006. The existing 40 MeV drift tube linac and rf cavities have been replaced by an electron cyclotron resonance (ECR) ion source embedded in a 200 kV high-voltage terminal and induction acceleration cells, respectively. A DA is, in principle, capable of accelerating any species of ion in all possible charge states. The KEK-DA is characterized by specific accelerator components such as a permanent magnet X-band ECR ion source, a low-energy transport line, an electrostatic injection kicker, an extraction septum magnet operated in air, combined-function main magnets, and an induction acceleration system. The induction acceleration method, integrating modern pulse power technology and state-of-art digital control, is crucial for the rapid-cycle KEK-DA. The key issues of beam dynamics associated with low-energy injection of heavy ions are beam loss caused by electron capture and stripping as results of the interaction with residual gas molecules and the closed orbit distortion resulting from relatively high remanent fields in the bending magnets. Attractive applications of this accelerator in materials and biological sciences are discussed.

  15. Digital terrain modeling with the Chebyshev polynomials

    CERN Document Server

    Florinsky, I V

    2015-01-01

    Mathematical problems of digital terrain analysis include interpolation of digital elevation models (DEMs), DEM generalization and denoising, and computation of morphometric variables by calculation of partial derivatives of elevation. Traditionally, these procedures are based on numerical treatments of two-variable discrete functions of elevation. We developed a spectral analytical method and algorithm based on high-order orthogonal expansions using the Chebyshev polynomials of the first kind with the subsequent Fejer summation. The method and algorithm are intended for DEM analytical treatment, such as, DEM global approximation, denoising, and generalization as well as computation of morphometric variables by analytical calculation of partial derivatives. To test the method and algorithm, we used a DEM of the Northern Andes including 230,880 points (the elevation matrix 480 $\\times$ 481). DEMs were reconstructed with 480, 240, 120, 60, and 30 expansion coefficients. The first and second partial derivatives ...

  1. A digital future for the history of psychology?

    Science.gov (United States)

    Green, Christopher D

    2016-08-01

    This article discusses the role that digital approaches to the history of psychology are likely to play in the near future. A tentative hierarchy of digital methods is proposed. A few examples are briefly described: a digital repository, a simple visualization using ready-made online database and tools, and more complex visualizations requiring the assembly of the database and, possibly, the analytic tools by the researcher. The relationship of digital history to the old "New Economic History" (Cliometrics) is considered. The question of whether digital history and traditional history need be at odds or, instead, might complement each other is woven throughout. The rapidly expanding territory of digital humanistic research outside of psychology is briefly discussed. Finally, the challenging current employment trends in history and the humanities more broadly are considered, along with the role that digital skills might play in mitigating those factors for prospective academic workers.

    Recent developments in digital technologies and the rise of the Internet have created new opportunities for citizen science. One of these has been the development of online citizen science games where complex research problems have been re-imagined as online multiplayer computer games. Some of the most successful examples of these can be found within the biological sciences, for example, Foldit, Phylo and EteRNA. These games offer scientists the opportunity to crowdsource research problems, and to engage with those outside the research community. Games also enable those without a background in science to make a valid contribution to research, and may also offer opportunities for informal science learning.

  12. Significant steps in the evolution of analytical chemistry--is the today's analytical chemistry only chemistry?

    Science.gov (United States)

    Karayannis, Miltiades I; Efstathiou, Constantinos E

    2012-12-15

    In this review the history of chemistry and specifically the history and the significant steps of the evolution of analytical chemistry are presented. In chronological time spans, covering the ancient world, the middle ages, the period of the 19th century, and the three evolutional periods, from the verge of the 19th century to contemporary times, it is given information for the progress of chemistry and analytical chemistry. During this period, analytical chemistry moved gradually from its pure empirical nature to more rational scientific activities, transforming itself to an autonomous branch of chemistry and a separate discipline. It is also shown that analytical chemistry moved gradually from the status of exclusive serving the chemical science, towards serving, the environment, health, law, almost all areas of science and technology, and the overall society. Some recommendations are also directed to analytical chemistry educators concerning the indispensable nature of knowledge of classical analytical chemistry and the associated laboratory exercises and to analysts, in general, why it is important to use the chemical knowledge to make measurements on problems of everyday life.

  17. Digital craftsmanship and education

    Directory of Open Access Journals (Sweden)

    Joaquín GARCÍA CARRASCO

    2015-04-01

    Full Text Available The culture, the craftsmanship and the educational activity are part of the extended phenotype of the human species. The craftwork functional structure is applied to works that use material tools and also to activities mediated by symbolic instruments as the language. The craftwork of incorporating into the culture, or into the education, employs symbolic instruments fundamentally. The large contingencies about the changes in the culture –the language, the writing, the information digitalisation– are the milestones in the evolution of the cultural heritage and the cultural incorporation processes. Our work provides elements to consider that undoubtedly the most apparent changes in the Knowledge Society are those related to information and communication technologies; but the changes in the cultural contents are not minor, which have fed the digital technological ecosystem. Hence the institutional project about cultural incorporation should be structured gradually to make intelligible the totality of the change in the vital human domain. That promoted changes have a global scope is a property of their expansion potential, like a toolbox of digital craftsmanship. But, basically, it is a revolutionary evolutionary continuity of the human craftwork condition; it remains a craftsman project; it implies a suitable handling of the material and symbolic instruments and an analytic capability to select relevant components of cultural development; the relevance property is dovetailed with significant elements of the cultural historical moment. However, it remains the quintessential human task, the essential artisan product and indispensable of humankind, the value of meaning. Joining into the culture implies a clarification of the cultural needs, also involves a process of deliberation and comprehension about the value of meaning of the practices in the Knowledge Society; entering in the value of meaning in the Knowledge Society is the element that

    There are some tensions between high-level policy definitions of “digital literacy” and actual teaching practice. We need to find workable definitions of digital literacy; obtain a better understanding of what digital literacy might look like in practice; and identify pedagogical approaches, which...... support teachers in designing digital literacy learning. We suggest that frameworks such as Problem Based Learning (PBL) are approaches that enable digital literacy learning because they provide good settings for engaging with digital literacy.

  4. Fields with Analytic Structure

    CERN Document Server

    Cluckers, Raf

    2009-01-01

    We present a unifying theory of fields with certain classes of analytic functions, called fields with analytic structure. Both real closed fields and Henselian valued fields are considered. For real closed fields with analytic structure, o-minimality is shown. For Henselian valued fields, both the model theory and the analytic theory are developed. We give a list of examples that comprises, to our knowledge, all principal, previously studied, analytic structures on Henselian valued fields, as well as new ones. The b-minimality is shown, as well as other properties useful for motivic integration on valued fields. The paper is reminiscent of [Denef, van den Dries, "p-adic and real subanalytic sets" Ann. of Math. (2) 128 (1988) 79--138], of [Cohen, Paul J. "Decision procedures for real and p-adic fields" Comm.

The presentation...... explores common research questions posed and analytical foci chosen by video game researchers subscribing to either the media effects tradition, represented by (ref.) or to interdisciplinary Game Studies. Both fields, which tend to depict themselves as polar-opposites, build on ethical assumptions...... of theoretical or analytical arrogance.

    In order to solve certain special CERN metrology problems, analytical terrestrial photogrammetry may have some advantages which are first discussed along with their drawbacks and limitations. In this application, it is necessary to carry out a rigorous and global adjustment of the observations and simultaneously process all the perspective ray bundles. The basic principles, the least squares solution and the stochastic analysis of the results are presented. However, for the CERN project, one wonders if the production of digital theodolites is going to reduce the advantages of the photogrammetric method. (12 refs).

    2012-01-01

    Paradigm research is an important issue of fundamental theory of information science in digital context. IS belongs to normal science which has multiple paradigms that are related each other and comparable. On the basis of litera- ture survey, this paper elucidates three typical paradigms of IS. The elucidation includes basic viewpoints and new ad- vances of each paradigm. It points out system/physical paradigm is highly related to information theory and technology tra- dition of IS. Controversy about this paradigm arises because of its problems such as the neglect of user, the relevance of in- formation theory to IS. Cognitive paradigm emerged as the alternative paradigm of the former one. Its scientific community becomes mature. New theories and models like holistic cognitive view are put forward to perfect the paradigm against the criticism that social dimension is ignored. Domain analysis paradigm attaches importance to epistemology and stresses on social-cultural context. It studies information problem from the perspective of knowledge domain and discourse community. As for the comparison and innovation of multi-paradigms in IS, it suggests that we IS scholars should compare fundamental assumptions and presuppositions of each paradigm from the view of metatheory. On basis of this work, a multi-paradigms framework of IS which can explains social information phenomenon from different dimensions should be constructed. 46 refs.%研究范式是数字化语境下信息科学基础理论研究的重要内容。信息科学是具有多元研究范式的常规科学,不同研究范式之间彼此关联,有可比性。本文在文献调研的基础上论述信息科学三种典型研究范式的基本观点和最新进展。系统/物理范式与信息论和技术传统关系密切,忽视信息用户和理论基础的适用性问题已成为该范式受到争议之所在。认知范式作为系统/物理范式的替代性范式而兴起,其科学共同体

    Full Text Available Research in digital libraries (DLs has gained much interest across the globe. Most funding related to DL are available for building DLs, rather than producing digital librarians by developing the DL curricula and offering necessary funding to introduce state-of-the-art DL labs for future library professionals. Based on online surveys, this article investigates the status of DL education/courses in Europe, particularly, it examines the curriculum contents of DL courses, explores the future direction of library and information science (LIS curricula, and identifies the competitors of LIS schools in the DL world. This study received responses from 54 LIS schools/departments in 27 European countries. The results of the current study clearly show that the majority of the LIS schools have already integrated digital librarianship in their regular bachelor’s and master’s degree programs. The importance of practical aspects in DL curricula has been highlighted by the authors. The study also reports the recommended books and journals on DL, direction of LIS curricula, and the competitors of LIS schools in the digital world. A number of future research directions have been offered by the authors. The authors expect that the study will contribute to the discussions and debates toward identifying subject elements for DL courses. The top subject areas based on their importance as reported by the participants of the current study should be taken into consideration before designing curricula for DLs and before developing a Europe-wide unique LIS curriculum.

However, these require large capital investments to implement and support the large volumes of data that needs to be analyzed to identify trends. They also require enormous processing power which places pressure on the business resources in addition to the dynamic changes in the digital technology. This paper evaluates the various nuances of business analytics of healthcare hosted on the cloud computing environment. The paper explores BI being offered as Software as a Service (SaaS solution towards offering meaningful use of information for improving functions in healthcare enterprise. It also attempts to identify the challenges that healthcare enterprises face when making use of a BI SaaS solution.

    Co-located collaboration can be extremely valuable during complex visual analytics tasks. We present an exploratory study of a system designed to support collaborative visual analysis tasks on a digital tabletop display. Fifteen participant pairs employed Cambiera, a visual analytics system, to solve a problem involving 240 digital documents. Our analysis, supported by observations, system logs, questionnaires, and interview data, explores how pairs approached the problem around the table. We contribute a unique, rich understanding of how users worked together around the table and identify eight types of collaboration styles that can be used to identify how closely people work together while problem solving. We show how the closeness of teams’ collaboration and communication influenced how they performed on the task overall. We further discuss the role of the tabletop for visual analytics tasks and derive design implications for future co-located collaborative tabletop problem solving systems.

    NCore is an open source architecture and software platform for creating flexible, collaborative digital libraries. NCore was developed by the National Science Digital Library (NSDL) project, and it serves as the central technical infrastructure for NSDL. NCore consists of a central Fedora-based digital repository, a specific data model, an API, and a set of backend services and frontend tools that create a new model for collaborative, contributory digital libraries. This paper describes NCore, presents and analyzes its architecture, tools and services; and reports on the experience of NSDL in building and operating a major digital library on it over the past year and the experience of the Digital Library for Earth Systems Education in porting their existing digital library and tools to the NCore platform.
