    Papadakis, I; Chrissikopoulos, V; Polemi, D

    2001-12-01

    In this paper, a secure medical digital library is presented. It is based on the CORBA specifications for distributed systems. The described approach relies on a three-tier architecture. Interaction between the medical digital library and its users is achieved through a Web server. The choice of employing Web technology for the dissemination of medical data has many advantages compared to older approaches, but also poses extra requirements that need to be fulfilled. Thus, special attention is paid to the distinguished nature of such medical data, whose integrity and confidentiality should be preserved at all costs. This is achieved through the employment of Trusted Third Parties (TTP) technology for the support of the required security services. Additionally, the proposed digital library employs smartcards for the management of the various security tokens that are used from the above services.

  6. Land Treatment Digital Library

    USGS Publications Warehouse

    Pilliod, David S.

    2009-01-01

    Across the country, public land managers make hundreds of decisions each year that influence landscapes and ecosystems within the lands they manage. Many of these decisions involve vegetation manipulations known as land treatments. Land treatments include activities such as removal or alteration of plant biomass, seeding burned areas, and herbicide applications. Data on these land treatments are usually stored at local offices, and gathering information across large spatial areas can be difficult. There is a need to centralize and store treatment data for Federal agencies involved in land treatments because these data are useful to land managers for policy and management and to scientists for developing sampling designs and studies. The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The project was developed and has been refined based on feedback from partner agencies and stakeholders, with opportunity for the library holdings to expand as new information becomes available. The library contains data in text, tabular, spatial, and image formats. Specific examples include project plans and implementation reports, monitoring data, spatial data files from geographic information systems, digitized paper maps, and digital images of land treatments. The data are entered by USGS employees and are accessible through a searchable web site. The LTDL can be used to respond to information requests, conduct analyses and other forms of information syntheses, produce maps, and generate reports for DOI managers and scientists and other authorized users.

  9. Architectural Optimization of Digital Libraries

    NASA Technical Reports Server (NTRS)

    Biser, Aileen O.

    1998-01-01

    This work investigates performance and scaling issues relevant to large scale distributed digital libraries. Presently, performance and scaling studies focus on specific implementations of production or prototype digital libraries. Although useful information is gained to aid these designers and other researchers with insights to performance and scaling issues, the broader issues relevant to very large scale distributed libraries are not addressed. Specifically, no current studies look at the extreme or worst case possibilities in digital library implementations. A survey of digital library research issues is presented. Scaling and performance issues are mentioned frequently in the digital library literature but are generally not the focus of much of the current research. In this thesis a model for a Generic Distributed Digital Library (GDDL) and nine cases of typical user activities are defined. This model is used to facilitate some basic analysis of scaling issues. Specifically, the calculation of Internet traffic generated for different configurations of the study parameters and an estimate of the future bandwidth needed for a large scale distributed digital library implementation. This analysis demonstrates the potential impact a future distributed digital library implementation would have on the Internet traffic load and raises questions concerning the architecture decisions being made for future distributed digital library designs.

    1991-07-01

    The Radiology Department at the University of Pennsylvania is in the process of clinically testing its PACS implementation. The PACS implementation has been built around a Vortech Image Archival and Retrieval System (IARS) with a 140-platter optical jukebox. The Vortech IARS provides archival services only. A set of software modules have been developed in-house that allow the system to function as a digital film library. The current implementation allows connectivity to a RIS (DECrad), supports the routing of images to two intensive care units, and allows image acquisition from a Du Pont FD2000 laser scanner and two GE SIGNA MR units. All process-to-process communication follows the ACR/NEMA 2.0 protocol. The proposed folder extensions to ACR/NEMA 2.0 are being utilized for sending information to the display nodes. The system has been running clinically for about three months. Details of the design, implementation, and functionality of the PACS are presented.

  18. The digital library: an oxymoron?

    PubMed

    Guédon, J C

    1999-01-01

    "Virtual libraries" and "digital libraries" have become stock phrases of our times. But what do they really mean? While digital refers to a new form of document encoding and must be approached from that perspective, virtual resonates with aspects that modern philosophy treats with benign neglect at best. The word virtual harbors the notion of potential, and therein lies its hidden strength. Although strong commercial interests try to use the shift to a digital environment to redefine the political economy of knowledge, and thus virtualize libraries into a state of almost complete impotence, all hope is not lost. Librarians of virtualized libraries may well discover that they have re-empowered institutions if they place human interaction at the heart of their operations. In other words, rather than envisioning themselves as knowledge bankers sitting on treasure vaults of knowledge, they should see themselves as "hearts" dynamizing human communities. They should also see themselves as an essential part of these communities, and not as external repositories of knowledge. In this fashion, they will avoid the fate of becoming an oxymoron.

    A higher spectral resolution is the main direction of developing remote sensing technology, and it is quite important to set up the digital ground object reflectance spectral database library, one of fundamental research fields in remote sensing application. Remote sensing application has been increasingly relying on ground object spectral characteristics, and quantitative analysis has been developed to a new stage. The present article summarized and systematically introduced the research status quo and development trend of digital ground object reflectance spectral libraries at home and in the world in recent years. Introducing the spectral libraries has been established, including desertification spectral database library, plants spectral database library, geological spectral database library, soil spectral database library, minerals spectral database library, cloud spectral database library, snow spectral database library, the atmosphere spectral database library, rocks spectral database library, water spectral database library, meteorites spectral database library, moon rock spectral database library, and man-made materials spectral database library, mixture spectral database library, volatile compounds spectral database library, and liquids spectral database library. In the process of establishing spectral database libraries, there have been some problems, such as the lack of uniform national spectral database standard and uniform standards for the ground object features as well as the comparability between different databases. In addition, data sharing mechanism can not be carried out, etc. This article also put forward some suggestions on those problems.

    Many scientists now manage the bulk of their bibliographic information electronically, thereby organizing their publications and citation material from digital libraries. However, a library has been described as “thought in cold storage,” and unfortunately many digital libraries can be cold, impersonal, isolated, and inaccessible places. In this Review, we discuss the current chilly state of digital libraries for the computational biologist, including PubMed, IEEE Xplore, the ACM digital library, ISI Web of Knowledge, Scopus, Citeseer, arXiv, DBLP, and Google Scholar. We illustrate the current process of using these libraries with a typical workflow, and highlight problems with managing data and metadata using URIs. We then examine a range of new applications such as Zotero, Mendeley, Mekentosj Papers, MyNCBI, CiteULike, Connotea, and HubMed that exploit the Web to make these digital libraries more personal, sociable, integrated, and accessible places. We conclude with how these applications may begin to help achieve a digital defrost, and discuss some of the issues that will help or hinder this in terms of making libraries on the Web warmer places in the future, becoming resources that are considerably more useful to both humans and machines.

    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.

    Hill, Linda L.; Janee, Greg; Dolin, Ron; Frew, James; Larsgaard, Mary

    1999-01-01

    Within a digital library, collections may range from an ad hoc set of objects that serve a temporary purpose to established library collections intended to persist through time. The objects in these collections vary widely, from library and data center holdings to pointers to real-world objects, such as geographic places, and the various metadata schemas that describe them. The key to integrated use of such a variety of collections in a digital library is collection metadata that represents the inherent and contextual characteristics of a collection. The Alexandria Digital Library (ADL) Project has designed and implemented collection metadata for several purposes: in XML form, the collection metadata "registers" the collection with the user interface client; in HTML form, it is used for user documentation; eventually, it will be used to describe the collection to network search agents; and it is used for internal collection management, including mapping the object metadata attributes to the common search parameters of the system.

Because of the rapid pace of information technology change, a digital library cannot be a static institution. Rather, it has to become a flexible organization adapted to continuous evolution of its infrastructure.

    Zhang, Hong; Lou, Shyhliang A.; Fan, Yu; Sickles, Edward A.; Huang, H. K.

    2000-05-01

    To practice mammography diagnosis effectively, radiologists expect convenient access to well-organized and authoritative mammography related information, especially when there is case in question. The purpose of this study is to build infrastructural diagnosis support by incorporating various clinical information into a digital mammography case library, and allow user to search the library based on mammographic findings. The digital mammography case library has a three- tier architecture: (1) Back-end mammography databases integrate multimedia clinical information from various operational systems, including RIS and PACS. Cases are stored in a finding index database powered by an object-relational database with finding-coded reports, which are modeled around the ACR BI-RADS (American College of Radiology, Breast Imaging Report and Data System) standard. (2) The middle-end application controllers process application logic, such as user authorization, HTTP request handling, database connection and dynamic HTML page generation. (3) Web-based user interface is developed for authorized Intranet personnel to formulate query based on radiological finding (such as mass, calcification and architectural distortion), shape and assessment, using ACR BI-RADS specified lexicon. The case library so far has 103 cases selected from over 800 digital mammography studies carried out at the Mt. Zion hospital, UCSF, during an on-going digital telemammography project. We believe that an Intranet based digital mammography case library with mammographic finding search capability facilitates continuous medical education and online decision support, by providing exemplary study to compare with case in question.

    1995-04-01

    As digital information proliferates and the difficulties of managing it threaten to overwhelm traditional publication and information delivery processes, new visions of a digital library are forming. Exactly what a digital library is and how it is to be organized have not yet been determined, and bibliographic organization of digital information has not been sufficiently addressed. Bibliography is the systematic description or classification of writings or publications considered as material objects. In today's digital world, such material objects may no longer be relevant, but the need for systematic description remains. The important issue is not whether digital bibliography is needed but, instead, whether or not existing bibliographic techniques are appropriate for this new media. A second issue is the location of the responsibility for a new digital bibliography. Does it rest with medical informaticians, often the producers of this new digital information, or with librarians, traditionally the classifiers of information? Developments in both medical informatics and medical librarianship indicate a need for greater collaboration between these specialties in order to achieve their common purpose--the creation, classification, and dissemination of scholarly information.

    The rapid increase in the price of electronic journals has made the optimization of collection management an urgent task. As there is currently no standard procedure for the evaluation of this problem, we applied the Reading Factor (RF), an electronically computed indicator used for consultation of individual articles. The aim of our study was to assess the cost effective impact of modifications in our digital library (i.e. change of access from the Intranet to the Internet or change in editorial policy). The digital OVID library at Rouen University Hospital continues to be cost-effective in comparison with the interlibrary loan costs. Moreover, when electronic versions are offered alongside a limited amount of interlibrary loans, a reduction in library costs was observed.

    A "Digital Divide" in information and technological literacy exists in Utah between small hospitals and clinics in rural areas and the larger health care institutions in the major urban area of the state. The goals of the outreach program of the Spencer S. Eccles Health Sciences Library at the University of Utah address solutions to this disparity in partnership with the National Network of Libraries of Medicine-- Midcontinental Region, the Utah Department of Health, and the Utah Area Health Education Centers. In a circuit-rider approach, an outreach librarian offers classes and demonstrations throughout the state that teach information-access skills to health professionals. Provision of traditional library services to unaffiliated health professionals is integrated into the library's daily workload as a component of the outreach program. The paper describes the history, methodology, administration, funding, impact, and results of the program.

  4. Electronic Health Record Meets Digital Library

    PubMed Central

    Humphreys, Betsy L.

    2000-01-01

    Linking the electronic health record to the digital library is a Web-era reformulation of the long-standing informatics goal of seamless integration of automated clinical data and relevant knowledge-based information to support informed decisions. The spread of the Internet, the development of the World Wide Web, and converging format standards for electronic health data and digital publications make effective linking increasingly feasible. Some existing systems link electronic health data and knowledge-based information in limited settings or limited ways. Yet many challenging informatics research problems remain to be solved before flexible and seamless linking becomes a reality and before systems become capable of delivering the specific piece of information needed at the time and place a decision must be made. Connecting the electronic health record to the digital library also requires positive resolution of important policy issues, including health data privacy, government envouragement of high-speed communications, electronic intellectual property rights, and standards for health data and for digital libraries. Both the research problems and the policy issues should be important priorities for the field of medical informatics. PMID:10984463

    The main goal of this research program is to develop and evaluate practices, frameworks, and tools for the design and construction of worldwide distributed digital music archives and libraries. Over the last few millennia, humans have amassed an enormous amount of musical information that is scattered around the world. It is becoming abundantly clear that the optimal path for acquisition is to distribute the task of digitizing the wealth of historical and cultural heritage material that exists in analogue formats, which may include books and manuscripts related to music, music scores, photographs, videos, audio tapes, and phonograph records. In order to achieve this goal, libraries, museums, and archives throughout the world, large or small, need well-researched policies, proper guidance, and efficient tools to digitize their collections and to make them available economically. The research conducted within the program addresses unique and imminent challenges posed by the digitization and dissemination of music media. The are four major research projects in progress: development and evaluation of digitization methods for preservation of analogue recordings; optical music recognition using microfilms; design of workflow management system with automatic metadata extraction; and formulation of interlibrary communication strategies.

    Introduction: The important role of information and communication technologies and their influence on methods of storing, retrieving information in digital libraries, has not only changed the meanings behind classic library activates but has also created great changes in their services. However, it seems that not all digital libraries provide their users with similar services and only some of them are successful in fulfilling their role in digital environment. The Iranian National Medical library is among those that appear to come short compared to other digital libraries around the world. By knowing the different services provided by digital libraries worldwide, one can evaluate the services provided by Iranian National Medical library. The goal of this study is a comparison between Iranian National Medical library and digital libraries of selected countries. Materials and Methods: This is an applied study and uses descriptive – survey method. The statistical population is the digital libraries around the world which were actively providing library services between October and December 2011 and were selected by using the key word “Digital Library” in Google search engine. The data-gathering tool was direct access to the websites of these digital libraries. The statistical study is descriptive and Excel software was used for data analysis and plotting of the charts. Results: The findings showed that among the 33 digital libraries investigated worldwide, most of them provided Browse (87.87%), Search (84.84%), and Electronic information retrieval (57.57%) services. The “Help” in public services (48/48%) and “Interlibrary Loan” in traditional services (27/27%) had the highest frequency. The Iranian National Medical library provides more digital services compared to other libraries but has less classic and public services and has less than half of possible public services. Other than Iranian National Medical library, among the 33 libraries investigated

    Introduction We have assembled a digital reflectance spectral library that covers the wavelength range from the ultraviolet to far infrared along with sample documentation. The library includes samples of minerals, rocks, soils, physically constructed as well as mathematically computed mixtures, plants, vegetation communities, microorganisms, and man-made materials. The samples and spectra collected were assembled for the purpose of using spectral features for the remote detection of these and similar materials. Analysis of spectroscopic data from laboratory, aircraft, and spacecraft instrumentation requires a knowledge base. The spectral library discussed here forms a knowledge base for the spectroscopy of minerals and related materials of importance to a variety of research programs being conducted at the U.S. Geological Survey. Much of this library grew out of the need for spectra to support imaging spectroscopy studies of the Earth and planets. Imaging spectrometers, such as the National Aeronautics and Space Administration (NASA) Airborne Visible/Infra Red Imaging Spectrometer (AVIRIS) or the NASA Cassini Visual and Infrared Mapping Spectrometer (VIMS) which is currently orbiting Saturn, have narrow bandwidths in many contiguous spectral channels that permit accurate definition of absorption features in spectra from a variety of materials. Identification of materials from such data requires a comprehensive spectral library of minerals, vegetation, man-made materials, and other subjects in the scene. Our research involves the use of the spectral library to identify the components in a spectrum of an unknown. Therefore, the quality of the library must be very good. However, the quality required in a spectral library to successfully perform an investigation depends on the scientific questions to be answered and the type of algorithms to be used. For example, to map a mineral using imaging spectroscopy and the mapping algorithm of Clark and others (1990a, 2003b

    Two years after the initial 2002 study, a greater number of academic health science libraries are offering digital reference chat services, and this number appears poised to grow in the coming years. This 2004 follow-up study found that 36 (27%) of the academic health science libraries examined provide digital chat reference services; this was an approximately 6% increase over the 25 libraries (21%) located in 2002. Trends in digital reference services in academic health science libraries were derived from the exploration of academic health science library Web sites and from digital correspondence with academic health science library personnel using e-mail and chat. This article presents an overview of the current state of digital reference service in academic health science libraries.

  18. Structured Course Objects in a Digital Library

    NASA Technical Reports Server (NTRS)

    Maly, K.; Zubair, M.; Liu, X.; Nelson, M.; Zeil, S.

    1999-01-01

    We are developing an Undergraduate Digital Library Framework (UDLF) that will support creation/archiving of courses and reuse of existing course material to evolve courses. UDLF supports the publication of course materials for later instantiation for a specific offering and allows the addition of time-dependent and student-specific information and structures. Instructors and, depending on permissions, students can access the general course materials or the materials for a specific offering. We are building a reference implementation based on NCSTRL+, a digital library derived from NCSTRL. Digital objects in NCSTRL+ are called buckets, self-contained entities that carry their own methods for access and display. Current bucket implementations have a two level structure of packages and elements. This is not a rich enough structure for course objects in UDLF. Typically, courses can only be modeled as a multilevel hierarchy and among different courses, both the syntax and semantics of terms may vary. Therefore, we need a mechanism to define, within a particular library, course models, their constituent objects, and the associated semantics in a flexible, extensible way. In this paper, we describe our approach to define and implement these multilayered course objects. We use XML technology to emulate complex data structures within the NCSTRL+ buckets. We have developed authoring and browsing tools to manipulate these course objects. In our current implementation a user downloading an XML based course bucket also downloads the XML-aware tools: an applet that enables the user to edit or browse the bucket. We claim that XML provides an effective means to represent multi-level structure of a course bucket.

Stegun, National Bureau of Standards Applied Mathematics Series v. 55 (U. S. Government Printing Office, Washington DC, 1964) presents the state of applied mathematics 40 years ago, in a form suited for computation in an age of numerical tables and mechanical calculators. Yet it remains a workhorse reference of AMO physics and of other scientific fields, having been cited in archival literature over 26,000 times since 1974 (at a still-increasing rate). To incorporate subsequent advances in basic mathematical knowledge, in computational power and technique, and in dissemination of information, the National Institute of Standards and Technology has begun a project to provide a modern source of evaluated mathematical reference data: the NIST Digital Library of Mathematical Functions. The Digital Library is designed to serve the needs of users of applied mathematics via the World Wide Web.

  4. Buckets: Smart Objects for Digital Libraries

    NASA Technical Reports Server (NTRS)

    Nelson, Michael L.

    2001-01-01

    Current discussion of digital libraries (DLs) is often dominated by the merits of the respective storage, search and retrieval functionality of archives, repositories, search engines, search interfaces and database systems. While these technologies are necessary for information management, the information content is more important than the systems used for its storage and retrieval. Digital information should have the same long-term survivability prospects as traditional hardcopy information and should be protected to the extent possible from evolving search engine technologies and vendor vagaries in database management systems. Information content and information retrieval systems should progress on independent paths and make limited assumptions about the status or capabilities of the other. Digital information can achieve independence from archives and DL systems through the use of buckets. Buckets are an aggregative, intelligent construct for publishing in DLs. Buckets allow the decoupling of information content from information storage and retrieval. Buckets exist within the Smart Objects and Dumb Archives model for DLs in that many of the functionalities and responsibilities traditionally associated with archives are pushed down (making the archives dumber) into the buckets (making them smarter). Some of the responsibilities imbued to buckets are the enforcement of their terms and conditions, and maintenance and display of their contents.

  16. Issues for bringing digital libraries into public use

    NASA Technical Reports Server (NTRS)

    Flater, David W.; Yesha, Yelena

    1993-01-01

    In much the same way that the field of artificial intelligence produced a cult which fervently believed that computers would soon think like human beings, the existence of electronic books has resurrected the paperless society as a utopian vision to some, an apocalyptic horror to others. In this essay we have attempted to provide realistic notions of what digital libraries are likely to become if they are a popular success. E-books are capable of subsuming most of the media we use today and have the potential for added functionality by being interactive. The environmental impact of having millions more computers will be offset to some degree, perhaps even exceeded, by the fact that televisions, stereos, VCR's, CD players, newspapers, magazines, and books will become part of the computer system or be made redundant. On the whole, large-scale use of digital libraries is likely to be a winning proposition. Whether or not this comes to pass depends on the directions taken by today's researchers and software developers. By involving the public, the effort being put into digital libraries can be leveraged into something which is big enough to make a real change for the better. If digital libraries remain the exclusive property of government, universities, and large research firms, then large parts of the world will remain without digital libraries for years to come, just as they have remained without digital phone service for far too long. If software companies try to scuttle the project by patenting crucial algorithms and using proprietary data formats, all of us will suffer. Let us reverse the errors of the past and create a truly open digital library system.

    The sophistication of computer technology and information transmission on internet has made various cyber information repository available to information consumers. In the era of information super-highway, the digital library which can be accessed from remote sites at any time is considered the prototype of information repository. Using object-oriented DBMS, the very first model of digital library for pharmaceutical researchers and related professionals in Korea has been developed. The published research papers and researchers' personal information was included in the database. For database with research papers, 13 domestic journals were abstracted and scanned for full-text image files which can be viewed by Internet web browsers. The database with researchers' personal information was also developed and interlinked to the database with research papers. These database will be continuously updated and will be combined with world-wide information as the unique digital library in the field of pharmacy.

  20. Integrating digital topology in image-processing libraries.

    PubMed

    Lamy, Julien

    2007-01-01

    This paper describes a method to integrate digital topology informations in image-processing libraries. This additional information allows a library user to write algorithms respecting topological constraints, for example, a seed fill or a skeletonization algorithm. As digital topology is absent from most image-processing libraries, such constraints cannot be fulfilled. We describe and give code samples for all the structures necessary for this integration, and show a use case in the form of a homotopic thinning filter inside ITK. The obtained filter can be up to a hundred times as fast as ITK's thinning filter and works for any image dimension. This paper mainly deals of integration within ITK, but can be adapted with only minor modifications to other image-processing libraries.

  1. Information retrieval in digital libraries: bringing search to the net.

    PubMed

    Schatz, B R

    1997-01-17

    A digital library enables users to interact effectively with information distributed across a network. These network information systems support search and display of items from organized collections. In the historical evolution of digital libraries, the mechanisms for retrieval of scientific literature have been particularly important. Grand visions in 1960 led first to the development of text search, from bibliographic databases to full-text retrieval. Next, research prototypes catalyzed the rise of document search, from multimedia browsing across local-area networks to distributed search on the Internet. By 2010, the visions will be realized, with concept search enabling semantic retrieval across large collections. PMID:8994022

  5. Java, Image Browsing, and the NCSA Astronomy Digital Image Library

    NASA Astrophysics Data System (ADS)

    Plante, R. L.; Goscha, D.

    We review our experience, including some lessons learned, with using Java to create data browsing tools for use with the Astronomy Digital Image Library (ADIL) and related digital library projects at NCSA\\@. We give an overview of our Image Data Browser, a generalized tool under development through a collaboration with the NCSA/NASA Project Horizon in support of access to earth and space science data. Emphasis has been placed on a design that can support a variety of data formats and applications both within and outside of astronomy. ADIL will use this tool in a variety of guises to browse and download images from the Library's collection. We see such a tool filling an important niche as a pipeline from a data repository to specialized, native data analysis software (e.g., IRAF, AIPS).

  6. The comparative effectiveness of conventional and digital image libraries.

    PubMed

    McColl, R I; Johnson, A

    2001-03-01

    Before introducing a hospital-wide image database to improve access, navigation and retrieval speed, a comparative study between a conventional slide library and a matching image database was undertaken to assess its relative benefits. Paired time trials and personal questionnaires revealed faster retrieval rates, higher image quality, and easier viewing for the pilot digital image database. Analysis of confidentiality, copyright and data protection exposed similar issues for both systems, thus concluding that the digital image database is a more effective library system. The authors suggest that in the future, medical images will be stored on large, professionally administered, centrally located file servers, allowing specialist image libraries to be tailored locally for individual users. The further integration of the database with web technology will enable cheap and efficient remote access for a wide range of users.

  8. Library outreach: addressing Utah's “Digital Divide”

    PubMed Central

    McCloskey, Kathleen M.

    2000-01-01

    A “Digital Divide” in information and technological literacy exists in Utah between small hospitals and clinics in rural areas and the larger health care institutions in the major urban area of the state. The goals of the outreach program of the Spencer S. Eccles Health Sciences Library at the University of Utah address solutions to this disparity in partnership with the National Network of Libraries of Medicine—Midcontinental Region, the Utah Department of Health, and the Utah Area Health Education Centers. In a circuit-rider approach, an outreach librarian offers classes and demonstrations throughout the state that teach information-access skills to health professionals. Provision of traditional library services to unaffiliated health professionals is integrated into the library's daily workload as a component of the outreach program. The paper describes the history, methodology, administration, funding, impact, and results of the program. PMID:11055305

Regular soundings of the atmosphere from near the surface into the mid-troposphere are essential for this research.

  11. Educating physicians to use the digital library.

    PubMed

    Florance, V; Braude, R M; Frisse, M E; Fuller, S

    1995-07-01

    Skill in creating, finding, managing, and using biomedical information is a vital component of modern medical practice. Medical schools recognize the revolutionary implications of computing technology and use a number of different strategies to integrate "informatics education" into their curricula. In many institutions, leadership for this effort rests with the health sciences library and/or the department of medical informatics. Examples are presented of how nine medical schools have implemented informatics education; no single informatics-education strategy prevails, and these schools' strategies do not exhaust the possibilities. Informatics education programs will require better planning and integration in the future because of the need to keep pace with curriculum reform, the changing context of medical practice, and the speed of technological innovation.

  18. Using narrative reports to support a digital library.

    PubMed

    Mendonça, E A; Cimino, J J; Johnson, S B

    2001-01-01

    The vast amount of information collected and stored in clinical systems can be a significant challenge in the integration of digital libraries and electronic medical records, especially the selection of clinical data to be used in the search, retrieval, and summarization processes. In this study, we describe the use of information retrieval measures with natural language processor output to identify critical information in narrative reports. Our hypothesis is that clinical data that occur often in narrative reports are less important to clinicians than findings that occur rarely. We used the information retrieval methods to analyze one year of discharge summaries. We then conducted a performance study, using physicians as subject. Results show that the methods can be used for filtering critical information from reports. Further studies need to be done on evaluation of the method based on an evaluation of the system performance in the context of a digital library.

  20. Visible threads: a smart VR interface to digital libraries

    NASA Astrophysics Data System (ADS)

    Borner, Katy

    2000-02-01

    The importance of information as a resource for economic growth and education is steadily increasing. Due to technological advances in computer industry and the explosive growth of the INternet much valuable information will be available in digital libraries. This paper introduces a system that aims to support a user's browsing activities in document sets retrieved from a digital library. Latent Semantic Analysis is applied to extract salient semantic structures and citation patterns of documents stored in a digital library in a comptutationally expensive batch job. At retrieval time, cluster techniques are used to organize retrieved documents into clusters according to the previously extracted semantic similarities. A modified Boltzman algorithm is employed to spatially organize the resulting clusters and their documents in the form of a 3D information landscape or 'i-scape'. THe i-scape is then displayed for interactive exploration via a multi- modal, virtual reality CAVE interface. Users' browsing activities are recorded and user models are extracted to give newcomers online help based on previous navigation activity as well as to enable experienced users to recognize and exploit past user traces. In this way, the system provides interactive services to assist users in the spatial navigation, interpretation, and detailed exploration of potentially large document sets matching a query.

    2002-01-01

    It is an honor to give the Lazerow lecture tonight and to discuss digital library developments from the perspective of working at a national laboratory. Tonight I would like to consider what lies ahead given the evolution in scientific research, how that impacts the development of digital libraries, and finally, look at some of the challenges ahead of us. I'm particularly interested in giving this talk tonight because it provides an opportunity to talk to those of you who are students. You represent the next generation of professionals who will to confront some of the challenges I will outline tonight, as well as those of you who are the mentors and teachers of the next generation. The two roles are pivotal in terms of the challenges on the horizon. Most of you are familiar with the information literacy challenges we face as a nation. As the library director of a national laboratory's science library, I am also acutely aware that we also have a real problem with the lack of scientific literacy within the general population in this country and it has a corresponding impact on decision-making in a technological society. Those of us engaged in supporting scientific research, or just generally interested, should be concerned about this fact because science and technology are at the foundation of our success as a nation in the 20th Century. For our nation to continue to be successful in the 21st Century, we will need to improve on the state of scientific literacy.

    Testi, Debora; Quadrani, Paolo; Viceconti, Marco

    2010-06-28

    Every research laboratory has a wealth of biomedical data locked up, which, if shared with other experts, could dramatically improve biomedical and healthcare research. With the PhysiomeSpace service, it is now possible with a few clicks to share with selected users biomedical data in an easy, controlled and safe way. The digital library service is managed using a client-server approach. The client application is used to import, fuse and enrich the data information according to the PhysiomeSpace resource ontology and upload/download the data to the library. The server services are hosted on the Biomed Town community portal, where through a web interface, the user can complete the metadata curation and share and/or publish the data resources. A search service capitalizes on the domain ontology and on the enrichment of metadata for each resource, providing a powerful discovery environment. Once the users have found the data resources they are interested in, they can add them to their basket, following a metaphor popular in e-commerce web sites. When all the necessary resources have been selected, the user can download the basket contents into the client application. The digital library service is now in beta and open to the biomedical research community. PMID:20478910

  19. An algorithmically optimized combinatorial library screened by digital imaging spectroscopy.

    PubMed

    Goldman, E R; Youvan, D C

    1992-12-01

    Combinatorial cassettes based on a phylogenetic "target set" were used to simultaneously mutagenize seven amino acid residues on one face of a transmembrane alpha helix comprising a bacteriochlorophyll binding site in the light harvesting II antenna of Rhodobacter capsulatus. This pigmented protein provides a model system for developing complex mutagenesis schemes, because simple absorption spectroscopy can be used to assay protein expression, structure, and function. Colony screening by Digital Imaging Spectroscopy showed that 6% of the optimized library bound bacteriochlorophyll in two distinct spectroscopic classes. This is approximately 200 times the throughput (ca. 0.03%) of conventional combinatorial cassette mutagenesis using [NN(G/C)]. "Doping" algorithms evaluated in this model system are generally applicable and should enable simultaneous mutagenesis at more positions in a protein than currently possible, or alternatively, decrease the screening size of combinatorial libraries.

    2001-01-01

    Many early web-based digital libraries (DLs) had implicit assumptions reflected in their architecture that the unit of focus in the DL (frequently "reports" or "e-prints") would only be manifested in a single, or at most a few, common file formats such as PDF or PostScript. DLs have now matured to the point where their contents are commonly no longer simple files. Complex objects in DLs have emerged from in response to various requirements, including: simple aggregation of formats and supporting files, bundling additional information to aid digital preservation, creating opaque digital objects for e-commerce applications, and the incorporation of dynamic services with the traditional data files. We examine a representative (but not necessarily exhaustive) number of current and recent historical web-based complex object technologies and projects that are applicable to DLs: Aurora, Buckets, ComMentor, Cryptolopes, Digibox, Document Management Alliance, FEDORA, Kahn-Wilensky Framework Digital Objects, Metadata Encoding & Transmission Standard, Multivalent Documents, Open eBooks, VERS Encapsulated Objects, and the Warwick Framework.

    We attempt to assess the publication impact of a digital library (DL) of aerospace scientific and technical information (STI). The Langley Technical Report Server (LTRS) is a digital library of over 1,400 electronic publications authored by NASA Langley Research Center personnel or contractors and has been available in its current World Wide Web (WWW) form since 1994. In this study, we examine calendar year 1997 usage statistics of LTRS and the Center for AeroSpace Information (CASI), a facility that archives and distributes hard copies of NASA and aerospace information. We also perform a citation analysis on some of the top publications distributed by LTRS. We find that although LTRS distributes over 71,000 copies of publications (compared with an estimated 24,000 copies from CASI), citation analysis indicates that LTRS has almost no measurable publication impact. We discuss the caveats of our investigation, speculate on possible different models of usage facilitated by DLs , and suggest retrieval analysis as a complementary metric to citation analysis. While our investigation failed to establish a relationship between LTRS and increased citations and raises at least as many questions as it answers, we hope it will serve as a invitation to, and guide for, further research in the use of DLs.

  6. Education for Digitization: A Case Studyon Sharing E-Information Resources in University Library

    NASA Astrophysics Data System (ADS)

    Zhu, Li-Hong

    This paper reported an international survey of library, information science (LIS), computer science faculty and websites, regarding digital libraries courses and curriculum at our institutions. We concluded that few universities currently offer courses on digital libraries while many universities have not developed Digital Library (DL) courses, even they are aware of the need to develop curriculum in this growing area of research and practice. The major aim of the paper is to present results from a survey on the current state of digital library education (DLE) in academic institutions. Additionally we examine the rationale and orientation for digital library education. We suggest several models that have emerged in the teaching of DLE and in incorporation of relevant topics into various curricula.

    The launching of an oceanographic expedition has its own brand of excitement, with the sound of the main engines firing up, and the lifting of the gangway in a foreign port, as the team of scientists and crew sets out for a month at sea with only the resources they have aboard. Although this adventure is broadly appealing, very few have the privilege of actually joining an expedition. With the "SIOExplorer" family of projects we are now beginning to open this experience across cyberspace to a wide range of students and teachers. What began two years ago as an effort to stabilize the Scripps Institution of Oceanography (SIO) data archives from more than 700 cruises going back 50 years, has now become an operational component of the National Science Digital Library (NSDL; www.nsdl.org), complete with thousands of historic photographs, full text documents and 3D visualization experiences. Our initial emphasis has been on marine geology and geophysics, in particular multibeam seafloor mapping, including 2 terabytes of digital objects. The IT architecture implemented at the San Diego Supercomputer Center (SDSC) streamlines the integration of additional projects in other disciplines with a suite of metadata management and collection building tools for "arbitrary digital objects." The "CruiseViewer" Java application is the primary portal to the digital library, providing a graphical user and display interface, the interface with the metadata database, and the interface with the SDSC "Storage Resource Broker" for long-term bulk distributed data storage management. It presents the user with a view of the available objects, overlaid on a global topography map. Geospatial objects can be selected interactively, and searches can be constrained by keywords. Metadata can be browsed and objects can be viewed onscreen or downloaded for further analysis, with automatic proprietary-hold request management. These efforts will be put to the test with national teacher workshops in the

    The AAS is sponsoring the development of a digital collection of online resources for teaching introductory astronomy: astronomycenter.org. Astronomy Center is part of the ComPADRE project with the AIP and its member organizations (see Deustua et al. at this meeting). The goal of Astronomy Center is to build a portal that will be a broad collection of high-quality digital resources, a useful and inviting interface to search and browse the collection, and an online meeting place for faculty at a variety of institutions to gather and share information. The collection will be launched in early 2005 and will initially contain a few hundred resources, selected primarily by Astronomy Center staff. The collection will grow through user and author submissions. Meanwhile, resources will be peer-reviewed and featured on the site as the collection grows. We will present the astronomycenter.org site, the user interface, some resources in the collection, the peer review process, and how members of the community can get involved with Astronomy Center. This work was made possible by a NSF National Science, Technology, Engineering and Mathematics Digital Library (NSDL) grant to the AAPT, AIP, and AAS.

    2005-01-01

    Objective: To meet the information needs of isolated primary care providers and their patients in the US Navy, a digital health sciences library, the Virtual Naval Hospital, was created through a unique partnership between academia and government. Methods: The creation of the digital library was heavily influenced by the principles of user-centered design and made allowances for the nomadic nature of the digital library's patrons and the heterogeneous access they have to Internet bandwidth. Results: The result is a digital library that has been in operation since 1997, continues to expand in size, is heavily used, and is highly regarded by its patrons. Conclusions: The digital library is dedicated to delivering the right information at the right time to the right person so the right decision can be made, and therefore the Virtual Naval Hospital functions as a knowledge-management system for the US Navy Bureau of Medicine and Surgery.

  11. Semantically Enriching the Search System of a Music Digital Library

    NASA Astrophysics Data System (ADS)

    de Juan, Paloma; Iglesias, Carlos

    Traditional search systems are usually based on keywords, a very simple and convenient mechanism to express a need for information. This is the most popular way of searching the Web, although it is not always an easy task to accurately summarize a natural language query in a few keywords. Working with keywords means losing the context, which is the only thing that can help us deal with ambiguity. This is the biggest problem of keyword-based systems. Semantic Web technologies seem a perfect solution to this problem, since they make it possible to represent the semantics of a given domain. In this chapter, we present three projects, Harmos, Semusici and Cantiga, whose aim is to provide access to a music digital library. We will describe two search systems, a traditional one and a semantic one, developed in the context of these projects and compare them in terms of usability and effectiveness.

    The integrated electronic resource that is forming in the astronomical community is a functional distributed digital library. As the balance of the literature comes on-line over the next year, and as more organizations seek to make data and other resources available on the Internet, ad hoc agreements among groups will give way to de facto standards. In our effort to extend the knowledge gained in our work on the electronic ApJ, we are engaged in an initiative to collaborate with other publishers and information distributors to utilize existing tools so that disparate collections may interoperate. We expect to devise effective operating conventions, and to articulate standard means for making valuable, archival information accessible on the net, reliably and for the long term.

    Museum fish collections possess a wealth of anatomical and morphological data that are essential for documenting and understanding biodiversity. Obtaining access to specimens for research, however, is not always practical and frequently conflicts with the need to maintain the physical integrity of specimens and the collection as a whole. Non-invasive three-dimensional (3D) digital imaging therefore serves a critical role in facilitating the digitization of these specimens for anatomical and morphological analysis as well as facilitating an efficient method for online storage and sharing of this imaging data. Here we describe the development of the Digital Fish Library (DFL, http://www.digitalfishlibrary.org), an online digital archive of high-resolution, high-contrast, magnetic resonance imaging (MRI) scans of the soft tissue anatomy of an array of fishes preserved in the Marine Vertebrate Collection of Scripps Institution of Oceanography. We have imaged and uploaded MRI data for over 300 marine and freshwater species, developed a data archival and retrieval system with a web-based image analysis and visualization tool, and integrated these into the public DFL website to disseminate data and associated metadata freely over the web. We show that MRI is a rapid and powerful method for accurately depicting the in-situ soft-tissue anatomy of preserved fishes in sufficient detail for large-scale comparative digital morphology. However these 3D volumetric data require a sophisticated computational and archival infrastructure in order to be broadly accessible to researchers and educators. PMID:22493695

    A digital archive, together with its users and its contents, does not exist in isolation; there is a cycle of activities which provides the context for the archive's existence. In arguing for the broadening of the traditional view of digital libraries as merely collections towards the processes of collecting and deploying, we have developed an extend ed digital library environment for orthopaedic surgeons which bridges the gap between the undertaking of experimental work and the dissemination of its results through electronic publication.

    1999-01-01

    Currently, there exist a large number of superb digital libraries, all of which are, unfortunately, vertically integrated and all presenting a monolithic interface to their users. Ideally, a user would want to locate resources from a variety of digital libraries dealing only with one interface. A number of approaches exist to this interoperability issue exist including: defining a universal protocol for all libraries to adhere to; or developing mechanisms to translate between protocols. The approach we illustrate in this paper is to push down the level of universal protocols to one for digital object communication and for communication for simple archives. This approach creates the opportunity for digital library service providers to create digital libraries tailored to the needs of user communities drawing from available archives and individual publishers who adhere to this standard. We have created a reference implementation based on the hyper text transfer protocol (http) with the protocols being derived from the Dienst protocol. We have created a special class of digital objects called buckets and a number of archives based on a NASA collection and NSF funded projects. Starting from NCSTRL we have developed a set of digital library services called NCSTRL+ and have created digital libraries for researchers, educators and students that can each draw on all the archives and individually created buckets.

Emerging digital library technology holds promise for allowing the creation of digital libraries and digital presses that can allow faculty and universities to bypass commercial publishers, retain control of their content, and distribute it directly to users, allowing the university and faculty to better serve their constituencies. The purpose of this paper is to show how this can be done. A methodology for overcoming the technical, social, political, and economic barriers involved in creating, distributing and organizing a digital library was developed, implemented, and refined over seven years.

    Applications of clustering and classification techniques can be proved very significant in both digital and physical (paper-based) libraries. The most essential application, document classification and clustering, is crucial for the content that is produced and maintained in digital libraries, repositories, databases, social media, blogs etc., based on various tags and ontology elements, transcending the traditional library-oriented classification schemes. Other applications with very useful and beneficial role in the new digital library environment involve document routing, summarization and query expansion. Paper-based libraries can benefit as well since classification combined with advanced material characterization techniques such as FTIR (Fourier Transform InfraRed spectroscopy) can be vital for the study and prevention of material deterioration. An improved two-level self-organizing clustering architecture is proposed in order to enhance the discrimination capacity of the learning space, prior to classification, yielding promising results when applied to the above mentioned library tasks.

    The diversity of the data held by the Geological Data Center at SIO is a tribute to the evolution of oceanography, from echo sounding rolls and hand-drawn charts to modern multibeam bathymetry. However, the changes in sensor technology and organizational approaches since 1903 present real challenges to the archivist, as we struggle to migrate the holdings into a web-accessible digital library for use by the public and scientific community (www.nsdl.org). Automation of the dataflow is an absolute necessity, with millions of files and a terabyte of data, although the biggest challenges come from complexity rather than bulk volume. The problems stem from our diverse archive collection, with its evolving data content, processing practices, naming conventions, and clutter from intermediate or obsolete files. This is not the only or the last data system to suffer from these problems, and an approach has been designed that can be applied to other projects. Instead of writing code to process each individual type of cruise, which varies from vessel to vessel over the fifty years and 795 cruises, we created a single Canonical Cruise Data Structure (CCDS). After some experimentation, the CCDS now consists of 9 basic categories and a reasonable number of sub-categories (directories) that can hold all the essential information. The key to flexibility and scalability comes from a template-driven rules approach that allows a processing script to harvest data from complex original data structures, and store them in the simple CCDS. The template mimics the structure of the CCDS. As the processing script traverses the template it finds rules for each category, instructing it on where to look for likely sources, and how to prioritize the results when multiple sources are detected. Over time as new situations are encountered, changes are simply made to the template, rather than the code. After the first tests, it became apparent that a visual method was needed to monitor the success

    BACKGROUND: Digital health sciences library (DHSL) evaluation involves studying the usage of the DHSL by individuals as well as populations. The purpose of this study was to evaluate trends in overall usage of a DHSL as part of a process of continuous quality improvement in order to learn how to enhance a DHSL in order to meet its users' needs better. METHODS: Web server log file analysis was performed on a prototype DHSL, the Virtual Hospital, using two log file analysis programs on data from the month of February over four consecutive years, 1995 to 1998. RESULTS: Overall DHSL usage increased between 1995 and 1997 and leveled off in 1998. Fifteen percent of usage came from countries outside the United States. A broad spectrum of medical information for health care providers and patients was accessed and centered around specialty medical information. CONCLUSIONS: To be of optimal assistance to users, DHSLs should (1) contain a broad base of information on common and uncommon medical problems, (2) accommodate the needs of the significant percentage of users that are international through content translation and mirroring, and (3) ensure they are indexed and catalogued in the major Web search engines and Web general and medical indices so they can be easily found by users.

    2013-01-01

    Forensic document analysis has become an important aspect of investigation of many different kinds of crimes from money laundering to fraud and from cybercrime to smuggling. The current workflow for analysts includes powerful tools, such as Palantir and Analyst s Notebook, for moving from evidence to actionable intelligence and tools for finding documents among the millions of files on a hard disk, such as FTK. However, the analysts often leave the process of sorting through collections of seized documents to filter out the noise from the actual evidence to a highly labor-intensive manual effort. This paper presents the Redeye Analysis Workbench, a tool to help analysts move from manual sorting of a collection of documents to performing intelligent document triage over a digital library. We will discuss the tools and techniques we build upon in addition to an in-depth discussion of our tool and how it addresses two major use cases we observed analysts performing. Finally, we also include a new layout algorithm for radial graphs that is used to visualize clusters of documents in our system.

    The Metathesaurus of the Unified Medical Language System (UMLS) offers the possibility of mapping between various medical vocabularies. The Primary Care Electronic Library (PCEL) contains a database of over six thousand Medical Subject Headings (MeSH terms) describing the resources of the electronic library. We were interested to know if it was possible to map from MeSH to the Systemized Nomenclature of Medicine Clinical Terms (SNOMED CT). Such a mapping would aid healthcare professionals to retrieve relevant data from our digital library as it would enable links between clinical systems and indexed material.

  1. Quark ACM with topologically generated gluon mass

    NASA Astrophysics Data System (ADS)

    Choudhury, Ishita Dutta; Lahiri, Amitabha

    2016-03-01

    We investigate the effect of a small, gauge-invariant mass of the gluon on the anomalous chromomagnetic moment (ACM) of quarks by perturbative calculations at one-loop level. The mass of the gluon is taken to have been generated via a topological mass generation mechanism, in which the gluon acquires a mass through its interaction with an antisymmetric tensor field Bμν. For a small gluon mass ( < 10 MeV), we calculate the ACM at momentum transfer q2 = -M Z2. We compare those with the ACM calculated for the gluon mass arising from a Proca mass term. We find that the ACM of up, down, strange and charm quarks vary significantly with the gluon mass, while the ACM of top and bottom quarks show negligible gluon mass dependence. The mechanism of gluon mass generation is most important for the strange quarks ACM, but not so much for the other quarks. We also show the results at q2 = -m t2. We find that the dependence on gluon mass at q2 = -m t2 is much less than at q2 = -M Z2 for all quarks.

    We describe NCSTRL+, a unified, canonical digital library for educational and scientific and technical information (STI). NCSTRL+ is based on the Networked Computer Science Technical Report Library (NCSTRL), a World Wide Web (WWW) accessible digital library (DL) that provides access to over 100 university departments and laboratories. NCSTRL+ implements two new technologies: cluster functionality and publishing "buckets". We have extended the Dienst protocol, the protocol underlying NCSTRL, to provide the ability to "cluster" independent collections into a logically centralized digital library based upon subject category classification, type of organization, and genres of material. The concept of "buckets" provides a mechanism for publishing and managing logically linked entities with multiple data formats. The NCSTRL+ prototype DL contains the holdings of NCSTRL and the NASA Technical Report Server (NTRS). The prototype demonstrates the feasibility of publishing into a multi-cluster DL, searching across clusters, and storing and presenting buckets of information.

    2004-03-01

    This is the second part of a two-part paper which explores methods that can be used to evaluate digital libraries in the health sector. Part 1 focuses on approaches to evaluation that have been proposed for mainstream digital information services. This paper investigates evaluative models developed for some innovative digital library projects, and some major national and international electronic health information projects. The value of ethnographic methods to provide qualitative data to explore outcomes, adding to quantitative approaches based on inputs and outputs is discussed. The paper concludes that new 'post-positivist' models of evaluation are needed to cover all the dimensions of the digital library in the health sector, and some ways of doing this are outlined.

  11. Integration of multimedia content and e-learning resources in a digital library

    NASA Astrophysics Data System (ADS)

    Pascual, Mireia; Ferran, Núria; Minguillón, Julià

    2006-01-01

    In this paper we describe a proposal for multimedia and e-learning content description based on standards interoperability within a digital library environment integrated in a virtual campus. In any virtual e-learning environment, a complex scenario which usually includes a digital library or, at least, a repository of learning resources, different levels of description are needed for all the elements: learning resources, multimedia content, activities, roles, etc. These elements can be described using library, e-learning and multimedia standards, depending on the specific needs of each particular scenario of use, but this might lead to an undesirable duplication of metadata, and to inefficient content queries and maintenance. Furthermore, there is a lack of semantic descriptions which makes all these contents merely become digital objects in the digital library, without exploiting all the possibilities in a e-learning virtual environment. Due to its flexibility and completeness, we propose to use the MPEG-7 standard for describing all the learning resources in the digital library, combined with the use of an ontology for a formal description of the learning process. The equivalences of Dublin Core, LOM and MPEG-7 standards are outlined, and the requirements of a proposal for a MPEG-7 based representation for all the contents in the digital library and the virtual classroom are described. The intellectual property policies for content sharing both within and among organizations are also addressed. With such proposal, it would be possible to build complex multimedia courses from a repository of learning objects using the digital library as the core repository.

    This article describes the development of a digital library as a resource for clinicians and researchers working with women with HIV infection. We wanted to find a new way of communicating the findings from the 114 studies that we used as the method case. The development of the SandBar Digital Library (http://sonweb.unc.edu/sandbar), a product of a 5-year project to develop the analytic techniques for qualitative metasynthesis, is described from its inception, including analyses of the potential users and how they might use such a resource. The Digital Library evolved over a 3-year period, with continuous feedback from a group of researchers and clinicians who are also experts in the care of HIV-positive people. It provides a concise and comprehensive compilation of findings in two major areas of concern for the seropositive women who were the participants in the studies: motherhood and stigma.

  9. MIT's 3.091 and NSDL Materials Digital Library: Investigating the Role of Digital Libraries in Freshmen Introductory Science Courses with No Lab Component

    NASA Astrophysics Data System (ADS)

    Sadoway, Donald; Bartolo, Laura

    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.

    NASA Astrophysics Data System (ADS)

    Moore, R.; Faerman, M.; Minster, J.; Day, S. M.; Ely, G.

    2003-12-01

    A community digital library provides support for ingestion, organization, description, preservation, and access of digital entities. The technologies that traditionally provide these capabilities are digital libraries (ingestion, organization, description), persistent archives (preservation) and data grids (access). We present a design for the SCEC community digital library that incorporates aspects of all three systems. Multiple groups have created integrated environments that sustain large-scale scientific data collections. By examining these projects, the following stages of implementation can be identified: \\begin{itemize} Definition of semantic terms to associate with relevant information. This includes definition of uniform content descriptors to describe physical quantities relevant to the scientific discipline, and creation of concept spaces to define how the uniform content descriptors are logically related. Organization of digital entities into logical collections that make it simple to browse and manage related material. Definition of services that are used to access and manipulate material in the collection. Creation of a preservation environment for the long-term management of the collection. Each community is faced with heterogeneity that is introduced when data is distributed across multiple sites, or when multiple sets of collection semantics are used, and or when multiple scientific sub-disciplines are federated. We will present the relevant standards that simplify the implementation of the SCEC community library, the resource requirements for different types of data sets that drive the implementation, and the digital library processes that the SCEC community library will support. The SCEC community library can be viewed as the set of processing steps that are required to build the appropriate SCEC reference data sets (SCEC approved encoding format, SCEC approved descriptive metadata, SCEC approved collection organization, and SCEC managed storage

  11. Simultaneous digital quantification and fluorescence-based size characterization of massively parallel sequencing libraries.

    PubMed

    Laurie, Matthew T; Bertout, Jessica A; Taylor, Sean D; Burton, Joshua N; Shendure, Jay A; Bielas, Jason H

    2013-08-01

    Due to the high cost of failed runs and suboptimal data yields, quantification and determination of fragment size range are crucial steps in the library preparation process for massively parallel sequencing (or next-generation sequencing). Current library quality control methods commonly involve quantification using real-time quantitative PCR and size determination using gel or capillary electrophoresis. These methods are laborious and subject to a number of significant limitations that can make library calibration unreliable. Herein, we propose and test an alternative method for quality control of sequencing libraries using droplet digital PCR (ddPCR). By exploiting a correlation we have discovered between droplet fluorescence and amplicon size, we achieve the joint quantification and size determination of target DNA with a single ddPCR assay. We demonstrate the accuracy and precision of applying this method to the preparation of sequencing libraries.

  15. Building a Digital Library from the Ground Up: an Examination of Emergent Information Resources in the Machine Learning Community

    NASA Astrophysics Data System (ADS)

    Cunningham, Sally Jo

    The current crop of digital libraries for the computing community are strongly grounded in the conventional library paradigm: they provide indexes to support searching of collections of research papers. As such, these digital libraries are relatively impoverished; the present computing digital libraries omit many of the documents and resources that are currently available to computing researchers, and offer few browsing structures. These computing digital libraries were built 'top down': the resources and collection contents are forced to fit an existing digital library architecture. A 'bottom up' approach to digital library development would begin with an investigation of a community's information needs and available documents, and then design a library to organize those documents in such a way as to fulfill the community's needs. The 'home grown', informal information resources developed by and for the machine learning community are examined as a case study, to determine the types of information and document organizations 'native' to this group of researchers. The insights gained in this type of case study can be used to inform construction of a digital library tailored to this community.

  1. Creating a Pediatric Digital Library for Pediatric Health Care Providers and Families

    PubMed Central

    D'Alessandro, Donna; Kingsley, Peggy

    2002-01-01

    The goal of this study was to complete a literature-based needs assessment with regard to common pediatric problems encountered by pediatric health care providers (PHCPs) and families, and to develop a problem-based pediatric digital library to meet those needs. The needs assessment yielded 65 information sources. Common problems were identified and categorized, and the Internet was manually searched for authoritative Web sites. The created pediatric digital library (www.generalpediatrics.com) used a problem-based interface and was deployed in November 1999. From November 1999 to November 2000, the number of hyperlinks and authoritative Web sites increased 51.1 and 32.2 percent, respectively. Over the same time, visitors increased by 57.3 percent and overall usage increased by 255 percent. A pediatric digital library has been created that begins to bring order to general pediatric resources on the Internet. This pediatric digital library provides current, authoritative, easily accessed pediatric information whenever and wherever the PHCPs and families want assistance. PMID:11861631

  4. Digital Libraries as a Component of Cyberinfrastructure: DLESE and the NSDL as Examples of Providing a Knowledge Layer to CI

    NASA Astrophysics Data System (ADS)

    Wright, M. J.; Marlino, M. R.

    2004-12-01

    Digital libraries have been identified in many reports and workshops as one component of cyberinfrastructure to not only support the aggregation and dissemination of materials, but as new architectures to support the development of networks of knowledge and understanding. The Digital Library for Earth System Education (DLESE) is aimed to support Earth system education, but is itself a component of a larger network of digital libraries in the sciences such as the National Science Digital Library (NSDL). These networks of libraries are envisioned to provide a "knowledge layer" over a broad array of heterogeneous components from data sets to learned articles, from data analysis to complex simulation environments. As cyberinfrastructure develops the tools and technologies to access and interact with data (for example in projects such as LEAD, GEON, THREDDS), the distinction between scientific data archiving, access and analysis, and the functions of a digital library continue to blur as we concentrate on the needs of the user, be they researcher, teacher or learner. Data analysis may be incorporated into more complex artifacts such as compound documents, simulation environments, and learning objects, which themselves must contain attributes and descriptions for understanding their context and use. Thus a cyberinfrastructure that incorporates the range of technologies of data access and analysis and digital libraries that can provide broad context must include mechanisms for interoperability through all levels of these infrastructures. New tools and approaches in digital library and information sciences can leverage the materials and relationships provided through this interoperability.

    2004-12-01

    The Enduring Resources for Earth Science Education (ERESE) project is a collaborative effort between earth scientists, educators, librarians and data archive managers. Its goal is to develop and maintain a persistent online research and education archive in a digital library environment that supports earth science education in plate tectonics. A major contribution from educators has been the development of inquiry lessons included in the digital library. Fourteen middle and high school teachers from across the country participated in the ERESE Workshop in July 2004. The goal of the workshop was three-fold: to provide the teachers with a research experience based on the digital library materials, to model an inquiry process and to support teachers as they develop inquiry lessons for their students. This process was led by a team of scientists and expert educators. The team used a master template to facilitate the teacher's lesson development. The pedagogical approach outlined in the template reflects a model of scientific thinking the goal of which is to shift from direction by the teacher at the onset of a lesson to a self-directed experience on the part of the student as they engage in the inquiry process and complete the lesson. Two examples of inquiry lessons produced as part of the workshop are reported here. The first investigates the symmetry of magnetic stripes at the northern East Pacific Rise using real marine geophysical data from the digital library. The second inquiry lesson was developed by a participant teacher and has been implemented this academic year by a high school marine science teacher. The lesson investigates the evidence that supports plate tectonics on the basis of the Pangea model. Having already been implemented in the classroom this lesson provides a rigorous testing of the inquiry process and the robustness of the scientific content of the digital library.

    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.

    2014-01-01

    PLLs for clock generation are essential for modern circuits, to generate specialized frequencies for many interfaces and high frequencies for chip internal operation. These circuits depend on analog circuits and careful tailoring for each new process, and making them fault tolerant is an incompletely solved problem. Until now, all digital PLLs have been restricted to sampled data DSP techniques and not available for the highest frequency baseband applications. This paper presents the design and preliminary evaluation of an all-digital baseband technique built entirely with an easily portable 10-cell digital library. The library is also described, as it aids in research and low volume design porting to new processes. The advantages of the digital approach are the wide variety of techniques available to give varying degrees of fault tolerance, and the simplicity of porting the design to new processes, even to exotic processes that may not have analog capability. The only tuning parameter is digital gate delay. An all-digital approach presents unique problems and standard analog loop stability design criteria cannot be directly used. Because of the quantization of frequency, there is effectively infinite gain for very small loop error feedback. The numerically controlled oscillator (NCO) based on a tapped delay line cannot be reliably updated while a pulse is active in the delay line, and ordinarily does not have enough frequency resolution for a low-jitter output.

    Chinese classical garden emphasizes not only the construction of building, mountains and rivers, spring and stone landscape but also the selection and configuration mode of the plant species. Yuanmingyuan, a classical work of Chinese garden art, is of both the magnificence of northern royal garden and the delicacy of southern private garden. The plants landscape in Yuanmingyuan also has its own unique style. But it is regretful that after several disasters, it nearly disappears just as other building clusters. The Re- Yuanmingyuan group re-presents the plants landscape of Yuanmingyuan through investigation, restoration and three-dimensional space generation, and makes proposal about the concept of digital plants library for the first time with the expectation to provide basic support for the digital restoration of cultural heritage by establishing the plants library. The paper also introduces the process of digital plants library system construction as well as the significance of the library construction for the landscape restoration in Yuanmingyuan and even the northern royal garden.

    2000-01-01

    Linking the electronic health record to the digital library is a Web-era reformulation of the long-standing informatics goal of seamless integration of automated clinical data and relevant knowledge-based information to support informed decisions. The spread of the Internet, the development of the World Wide Web, and converging format standards for electronic health data and digital publications make effective linking increasingly feasible. Some existing systems link electronic health data and knowledge-based information in limited settings or limited ways. Yet many challenging informatics research problems remain to be solved before flexible and seamless linking becomes a reality and before systems become capable of delivering the specific piece of information needed at the time and place a decision must be made. Connecting the electronic health record to the digital library also requires positive resolution of important policy issues, including health data privacy, government encouragement of high-speed communications, electronic intellectual property rights, and standards for health data and for digital libraries. Both the research problems and the policy issues should be important priorities for the field of medical informatics.

  1. How to recycle asbestos containing materials (ACM)

    SciTech Connect

    Jantzen, C.M.

    2000-04-11

    The current disposal of asbestos containing materials (ACM) in the private sector consists of sealing asbestos wetted with water in plastic for safe transportation and burial in regulated land fills. This disposal methodology requires large disposal volumes especially for asbestos covered pipe and asbestos/fiberglass adhering to metal framework, e.g. filters. This wrap and bury technology precludes recycle of the asbestos, the pipe and/or the metal frameworks. Safe disposal of ACM at U.S. Department of Energy (DOE) sites, likewise, requires large disposal volumes in landfills for non-radioactive ACM and large disposal volumes in radioactive burial grounds for radioactive and suspect contaminated ACM. The availability of regulated disposal sites is rapidly diminishing causing recycle to be a more attractive option. Asbestos adhering to metal (e.g., pipes) can be recycled by safely removing the asbestos from the metal in a patented hot caustic bath which prevents airborne contamination /inhalation of asbestos fibers. The dissolution residue (caustic and asbestos) can be wet slurry fed to a melter and vitrified into a glass or glass-ceramic. Palex glasses, which are commercially manufactured, are shown to be preferred over conventional borosilicate glasses. The Palex glasses are alkali magnesium silicate glasses derived by substituting MgO for B{sub 2}O{sub 3} in borosilicate type glasses. Palex glasses are very tolerant of the high MgO and high CaO content of the fillers used in forming asbestos coverings for pipes and found in boiler lashing, e.g., hydromagnesite (3MgCO{sub 3} Mg(OH){sub 2} 3H{sub 2}O) and plaster of paris, gypsum (CaSO{sub 4}). The high temperate of the vitrification process destroys the asbestos fibers and renders the asbestos non-hazardous, e.g., a glass or glass-ceramic. In this manner the glass or glass-ceramic produced can be recycled, e.g., glassphalt or glasscrete, as can the clean metal pipe or metal framework.

    The purpose of this paper is twofold: to describe robust rationales for integrating inquiry-based learning into undergraduate science education, and to propose that digital libraries are potentially powerful technological tools that can support inquiry-based learning goals in undergraduate science courses. Overviews of constructivism and situated cognition are provided with regard to how these two theoretical perspectives have influenced current science education reform movements, especially those that involve inquiry-based learning. The role that digital libraries can play in inquiry-based learning environments is discussed. Finally, the importance of alignment among critical pedagogical dimensions of an inquiry-based pedagogical framework is stressed in the paper, and an example of how this can be done is presented using earth science education as a context.

    Carefully collected, high-quality data are crucial in biomedical visualization, and it is important that the user community has ready access to both this data and the high-performance computing resources needed by the complex, computational algorithms that will process it. Biological researchers generally require data, tools and algorithms from multiple providers to achieve their goals. This paper illustrates our response to the problems that result from this. The Living Human Digital Library (LHDL) project presented in this paper has taken advantage of Web Services to build a biomedical digital library infrastructure that allows clinicians and researchers not only to preserve, trace and share data resources, but also to collaborate at the data-processing level.

    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. Future releases will allow publishers to attach media rich information about the data collection, as well as additional information about scientific results, and papers and web pages that reference the data collection. The presentation will discuss the current implementation, and future directions.

    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.

    1995-01-01

    The authors compiled a digital case library, a database of cases for intracranial masses, that can be used as an electronic teaching file and image source for case-based teaching applications, electronic textbooks, and diagnosis support tools. The library is a relational database with a feature-coded image archive that is structured around relevant radiologic findings. Its index for coding image content is structured as a hierarchical image description index that uses the relational format. Rules that control the search direction within the library and that generate lists of diagnostic hypotheses for decision support tools are embedded within the database structure. Currently, the library consists of 200 cases and 1,100 images that present intracranial masses on radiographs, computed tomograms, magnetic resonance images, and angiograms. Each image in the library is indexed according to its radiologic content. The user may search for reference images that contain particular radiologic features by formulating image content-based queries. The hierarchical index of radiologic findings allows multilevel query formulation that depends on the user's level of experience.

  16. Enhancing Access to Audio and Video Collections of Raman Research Institute Library through Digitization

    NASA Astrophysics Data System (ADS)

    Nagaraj, M. N.; Benegal, V. J.; Bhandi, M. K.

    2015-04-01

    The library at the Raman Research (RRI) began digitization of its audio and video (AV) collections starting in the year 2000 with the intent to enhance the accessibility of these items. AV collections in their original format are problematic since they are vulnerable to physical damage and decay in uncontrolled climate conditions. Further, as AV formats have changed over the years, older formats become unreadable due to the fact that the equipment needed to view such materials is obsolete or no longer available. This paper will show how RRI has taken multiple measures to address these various problems. At first, catalogue records were enhanced with additional metadata, but this did not sufficiently enhance access. Next, the library converted the AV materials to CDs, but this format also posed various problems, as CDs are susceptible to damage and do not allow for multiple simultaneous use. Finally, the RRI library digitized AV materials and placed them on the RRI intranet and the web for wider accessibility.

    Kurtz, Michael J.; Eichhorn, Guenther; Accomazzi, Alberto; Grant, Carolyn S.; Demleitner, Markus; Murray, Stephen S.

    The NASA Astrophysics Data System (ADS), along with astronomy's journals and data centers (a collaboration dubbed URANIA), has developed a distributed on-line digital library which has become the dominant means by which astronomers search, access and read their technical literature. Digital libraries permit the easy accumulation of a new type of bibliometric measure, the number of electronic accesses (``reads'') of individual articles. By combining data from the text, citation, and reference databases with data from the ADS readership logs we have been able to create Second Order Bibliometric Operators, a customizable class of collaborative filters which permits substantially improved accuracy in literature queries. Using the ADS usage logs along with membership statistics from the International Astronomical Union and data on the population and gross domestic product (GDP) we develop an accurate model for world-wide basic research where the number of scientists in a country is proportional to the GDP of that country, and the amount of basic research done by a country is proportional to the number of scientists in that country times that country's per capita GDP. We introduce the concept of utility time to measure the impact of the ADS/URANIA and the electronic astronomical library on astronomical research. We find that in 2002 it amounted to the equivalent of 736 FTE researchers, or 250 Million, or the astronomical research done in France.

    We have developed an automated quality control (QC) platform for next-generation sequencing (NGS) library characterization by integrating a droplet-based digital microfluidic (DMF) system with a capillary-based reagent delivery unit and a quantitative CE module. Using an in-plane capillary-DMF interface, a prepared sample droplet was actuated into position between the ground electrode and the inlet of the separation capillary to complete the circuit for an electrokinetic injection. Using a DNA ladder as an internal standard, the CE module with a compact LIF detector was capable of detecting dsDNA in the range of 5-100 pg/μL, suitable for the amount of DNA required by the Illumina Genome Analyzer sequencing platform. This DMF-CE platform consumes tenfold less sample volume than the current Agilent BioAnalyzer QC technique, preserving precious sample while providing necessary sensitivity and accuracy for optimal sequencing performance. The ability of this microfluidic system to validate NGS library preparation was demonstrated by examining the effects of limited-cycle PCR amplification on the size distribution and the yield of Illumina-compatible libraries, demonstrating that as few as ten cycles of PCR bias the size distribution of the library toward undesirable larger fragments.

    The escalating competition between online pornography - seeking and disseminating behaviors and technologies that attempt to reduce them creates technical, semantic and legal barriers to the legitimate discussion of and education about sensitive health issues involving sexuality, anatomy and pathology, especially when image-based knowledge is used. The effects of this competition on the use and management of an online dermatology atlas are described with a discussion on the importance of anticipating, addressing and controlling this problem while developing and maintaining image-based digital libraries and other e-Health applications.

  4. Developing Archive Information Packages for Data Sets: Early Experiments with Digital Library Standards

    2008-12-01

    The key to interoperability between systems is often metadata, yet metadata standards in the digital library and data center communities have evolved separately. In the data center world NASA's Directory Interchange Format (DIF), the Content Standard for Digital Geospatial Metadata (CSDGM), and most recently the international Geographic Information: Metadata (ISO 19115:2003) are used for descriptive metadata at the data set level to allow catalog interoperability; but use of anything other than repository- based metadata standards for the individual files that comprise a data set is rare, making true interoperability, at the data rather than data set level, across archives difficult. While the Open Archival Information Systems (OAIS) Reference Model with its call for creating Archive Information Packages (AIP) containing not just descriptive metadata but also preservation metadata is slowly being adopted in the community, the PREservation Metadata Implementation Strategies (PREMIS) standard, the only extant OAIS- compliant preservation metadata standard, has scarcely even been recognized as being applicable to the community. The digital library community in the meantime has converged upon the Metadata Encoding and Transmission Standard (METS) for interoperability between systems as evidenced by support for the standard by digital library systems such as Fedora and Greenstone. METS is designed to allow inclusion of other XML-based standards as descriptive and administrative metadata components. A recent Stanford study suggests that a combination of METS with included FGDC and PREMIS metadata could work well for individual granules of a data set. However, some of the lessons learned by the data center community over the last 30+ years of dealing with digital data are 1) that data sets as a whole need to be preserved and described and 2) that discovery and access mechanisms need to be hierarchical. Only once a user has reviewed a data set description and determined

    The NASA Astrophysics Data System (ADS) is the central part of the Digital Library in Astronomy. The astronomical community in the last decade has built a system of interlinked data centers that is unique among the sciences. It is composed of the closely integrated operations of the ADS, CDS, NED, other data and archive centers, and the astronomical journals. It began functioning in 1993 with the ability to make joint queries to the ADS and the SIMBAD database at the CDS. It now provides the user with a tightly integrated web of information links. The ADS provides access to over 2.6 million abstracts and over 2 million scanned pages from 276,000 journal articles. One important part of the ADS is the archive of the historical literature. This archive includes all the major journals back to volume 1, as well as about 300,000 pages of scanned historical observatory publications. The list of references that is returned from a query includes an extensive set of links to many different on-line data sources for each reference. Currently there are over 6 million links in the ADS, about half of these to information sources outside the ADS. This extensive linking to other on-line resources makes the ADS and the Astronomy Digital Library unique in the sciences. The ADS is funded by NASA and is accessible without restrictions at: ADS

    Users of digital image libraries are often not interested in image data per se but in derived products such as catalogs of objects of interest. Converting an image database into a usable catalog is typically carried out manually at present. For many larger image databases the purely manual approach is completely impractical. In this paper we describe the development of a trainable cataloging system: the user indicates the location of the objects of interest for a number of training images and the system learns to detect and catalog these objects in the rest of the database. In particular we describe the application of this system to the cataloging of small volcanoes in radar images of Venus. The volcano problem is of interest because of the scale (30,000 images, order of 1 million detectable volcanoes), technical difficulty (the variability of the volcanoes in appearance) and the scientific importance of the problem. The problem of uncertain or subjective ground truth is of fundamental importance in cataloging problems of this nature and is discussed in some detail. Experimental results are presented which quantify and compare the detection performance of the system relative to human detection performance. The paper concludes by discussing the limitations of the proposed system and the lessons learned of general relevance to the development of digital image 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. PMID:24768172

    OBJECTIVE: Develop a framework for collections-based access to networked information sources that addresses the problem of location-dependent access to information sources. DESIGN: This framework uses a metaphor of a virtual shelf. A virtual shelf is a general-purpose server that is dedicated to a particular information subject class. The identifier of one of these servers identifies its subject class. Location-independent call numbers are assigned to information sources. Call numbers are based on standard vocabulary codes. The call numbers are first mapped to the location-independent identifiers of virtual shelves. When access to an information resource is required, a location directory provides a second mapping of these location-independent server identifiers to actual network locations. RESULTS: The framework has been implemented in two different systems. One system is based on the Open System Foundation/Distributed Computing Environment and the other is based on the World Wide Web. CONCLUSIONS: This framework applies in new ways traditional methods of library classification and cataloging. It is compatible with two traditional styles of selecting information searching and browsing. Traditional methods may be combined with new paradigms of information searching that will be able to take advantage of the special properties of digital information. Cooperation between the library-informational science community and the informatics community can provide a means for a continuing application of the knowledge and techniques of library science to the new problems of networked information sources.

    Globally resolvable, persistent digital identifiers have become an essential tool to enable unambiguous links between published research results and their underlying digital resources. In addition, this unambiguous identification allows citation. In an ideal research world, any scientific content should be citable and the coherent content, as well as the citation itself, should be persistent. However, today's scientists do not just produce traditional research papers - they produce comprehensive digital collections of objects which, alongside digital texts, include digital resources such as research data, audiovisual media, digital lab journals, images, statistics and software code. Researchers start to look for services which allow management of these digital resources with minimum time investment. In light of this, we show how the German National Library of Science and Technology (TIB) develops supportive frameworks to accompany the life cycle of scientific knowledge generation and transfer. This includes technical infrastructures for • indexing, cataloguing, digital preservation, DOI names and licencing for text and digital objects (the TIB DOI registration, active since 2004) and • a digital repository for the deposition and provision of accessible, traceable and citeable research data (RADAR). One particular problem for the management of data originating from (collaborating) research infrastructures is their dynamic nature in terms of growth, access rights and quality. On a global scale, systems for access and preservation are in place for the big data domains (e.g. environmental sciences, space, climate). However, the stewardship for disciplines without a tradition of data sharing, including the fields of the so-called long tail, remains uncertain. The RADAR - Research Data Repository - project establishes a generic end-point data repository, which can be used in a collaborative way. RADAR enables clients to upload, edit, structure and describe their

    High-fidelity computer-based modeling, simulation and visualization systems for the study of temporal bone anatomy and training for middle ear surgery are based on a sequence of digital anatomical images, which must cover a large tissue volume and yet display details in high resolution and with high fidelity. However, the use of existing image libraries by independent developers of virtual models of the ear is limited by copyright protection and low image resolution. A fresh frozen human temporal bone was CT-scanned and serially sectioned at 25 microm and digital images of the block surface were recorded at 50- to 100-microm increments with a Light Phase(TM) single-shot camera back attachment. A total of 605 images were recorded in 24-bit RGB resolution. After color correction and elimination of image size variation by differential cropping to 15.4 cm x 9.7 cm, all images were resampled to 3,078 x 1,942 pixels at a final resolution of 50 microm/pixel and stored as 605 one-Mb JPEG files together with a three-dimensional viewer. The resulting complete set of image data provides: (1) a source material suitable for generating computer models of the human ear; (2) a resource of high-quality digital images of anatomical cross sections from the human ear, and (3) a PC-based viewer of the temporal bone in three perpendicular planes of section.

    Lactococcus lactis expresses the homologous glucosaminidases AcmB, AcmC, AcmA and AcmD. The latter two have three C-terminal LysM repeats for peptidoglycan binding. AcmD has much shorter intervening sequences separating the LysM repeats and a lower iso-electric point (4.3) than AcmA (10.3). Under standard laboratory conditions AcmD was mainly secreted into the culture supernatant. An L. lactis acmAacmD double mutant formed longer chains than the acmA single mutant, indicating that AcmD contributes to cell separation. This phenotype could be complemented by plasmid-encoded expression of AcmD in the double mutant. No clear difference in cellular lysis and protein secretion was observed between both mutants. Nevertheless, overexpression of AcmD resulted in increased autolysis when AcmA was present (as in the wild type strain) or when AcmA was added to the culture medium of an AcmA-minus strain. Possibly, AcmD is mainly active within the cell wall, at places where proper conditions are present for its binding and catalytic activity. Various fusion proteins carrying either the three LysM repeats of AcmA or AcmD were used to study and compare their cell wall binding characteristics. Whereas binding of the LysM domain of AcmA took place at pHs ranging from 4 to 8, LysM domain of AcmD seems to bind strongest at pH 4. PMID:23951292

    This paper describes a content-based image retrieval digital library that supports geographical image retrieval over a testbed of 800 aerial photographs, each 25 megabytes in size. In addition, this paper also introduces a methodology to evaluate the performance of the algorithms in the prototype system. There are two major contributions: we suggest an approach that incorporates various image processing techniques including Gabor filters, image enhancement and image compression, as well as information analysis techniques such as the self-organizing map (SOM) into an effective large-scale geographical image retrieval system. We present two experiments that evaluate the performance of the Gabor-filter-extracted features along with the corresponding similarity measure against that of human perception, addressing the lack of studies in assessing the consistency between an image representation algorithm or an image categorization method and human mental model.

  18. Taking control of your digital library: how modern citation managers do more than just referencing.

    PubMed

    Mahajan, Amit K; Hogarth, D Kyle

    2013-12-01

    Physicians are constantly navigating the overwhelming body of medical literature available on the Internet. Although early citation managers were capable of limited searching of index databases and tedious bibliography production, modern versions of citation managers such as EndNote, Zotero, and Mendeley are powerful web-based tools for searching, organizing, and sharing medical literature. Effortless point-and-click functions provide physicians with the ability to develop robust digital libraries filled with literature relevant to their fields of interest. In addition to easily creating manuscript bibliographies, various citation managers allow physicians to readily access medical literature, share references for teaching purposes, collaborate with colleagues, and even participate in social networking. If physicians are willing to invest the time to familiarize themselves with modern citation managers, they will reap great benefits in the future.

  19. Next-generation applications in healthcare digital libraries using semantic service composition and coordination.

    PubMed

    Möller, Thorsten; Schuldt, Heiko; Gerber, Andreas; Klusch, Matthias

    2006-06-01

    Healthcare digital libraries (DLs) increasingly make use of dedicated services to access functionality and/or data. Semantic (web) services enhance single services and facilitate compound services, thereby supporting advanced applications on top of a DL. The traditional process management approach tends to focus on process definition at build time rather than on actual service events in run time, and to anticipate failures in order to define appropriate strategies. This paper presents a novel approach where service coordination is distributed among a set of agents. A dedicated component plans compound semantic services on demand for a particular application. In failure, the planner is reinvoked to define contin- gency strategies. Finally, matchmaking is effected at runtime by choosing the appropriate service provider. These combined technologies will provide key support for highly flexible next-generation DL applications. Such technologies are under development within CASCOM.

    In this paper, we address the issue of computer-assisted indexing in one specific case, i.e., for the 17,000 digitized images of the spine acquired during the National Health and Nutrition Examination Survey (NHANES). The crucial step in this process is to accurately segment the cervical and lumbar spine in the radiographic images. To that end, we have implemented a unique segmentation system that consists of a suite of spine-customized automatic and semi-automatic statistical shape segmentation algorithms. Using the aforementioned system, we have developed experiments to optimally generate a library of spine segmentations, which currently include 2000 cervical and 2000 lumbar spines. This work is expected to contribute toward the creation of a biomedical Content-Based Image Retrieval system that will allow retrieval of vertebral shapes by using query by image example or query by shape example.

    2015-12-01

    Recent developments in machine reading and learning approaches to text and data mining hold considerable promise for accelerating the pace and quality of literature-based data synthesis, but these advances have outpaced even basic levels of access to the published literature. For many geoscience domains, particularly those based on physical samples and field-based descriptions, this limitation is significant. Here we describe a general infrastructure to support published literature-based machine reading and learning approaches to information integration and knowledge base creation. This infrastructure supports rate-controlled automated fetching of original documents, along with full bibliographic citation metadata, from remote servers, the secure storage of original documents, and the utilization of considerable high-throughput computing resources for the pre-processing of these documents by optical character recognition, natural language parsing, and other document annotation and parsing software tools. New tools and versions of existing tools can be automatically deployed against original documents when they are made available. The products of these tools (text/XML files) are managed by MongoDB and are available for use in data extraction applications. Basic search and discovery functionality is provided by ElasticSearch, which is used to identify documents of potential relevance to a given data extraction task. Relevant files derived from the original documents are then combined into basic starting points for application building; these starting points are kept up-to-date as new relevant documents are incorporated into the digital library. Currently, our digital library stores contains more than 360K documents supplied by Elsevier and the USGS and we are actively seeking additional content providers. By focusing on building a dependable infrastructure to support the retrieval, storage, and pre-processing of published content, we are establishing a foundation for

  13. Extracting scientific articles from a large digital archive: BioStor and the Biodiversity Heritage Library

    PubMed Central

    2011-01-01

    Background The Biodiversity Heritage Library (BHL) is a large digital archive of legacy biological literature, comprising over 31 million pages scanned from books, monographs, and journals. During the digitisation process basic metadata about the scanned items is recorded, but not article-level metadata. Given that the article is the standard unit of citation, this makes it difficult to locate cited literature in BHL. Adding the ability to easily find articles in BHL would greatly enhance the value of the archive. Description A service was developed to locate articles in BHL based on matching article metadata to BHL metadata using approximate string matching, regular expressions, and string alignment. This article locating service is exposed as a standard OpenURL resolver on the BioStor web site http://biostor.org/openurl/. This resolver can be used on the web, or called by bibliographic tools that support OpenURL. Conclusions BioStor provides tools for extracting, annotating, and visualising articles from the Biodiversity Heritage Library. BioStor is available from http://biostor.org/. PMID:21605356

    2006-12-01

    The Computational Science Education Reference Desk, a Pathway project of the National Science Digital Library, is establishing quality control processes to ensure quality of learning objects in its catalog. Objects in the catalog typically involve simulations, and we apply standard verification and validation processes for the simulation and modeling community to each object. Additionally, we use an accreditation process to ensure the appropriateness of materials for their intended audience. The process has been piloted initially with computational biology, chemistry, and mathematics materials in the CSERD catalog, and we are currently seeking reviewers to assist in the evaluation of objects in the fields of physics and astronomy. The initial testing of our review process has shown that a significant portion of the work in reviewing learning objects can be performed by appropriately selected undergraduates, and the results of using undergraduates in science-content degrees for validation testing as well as students in education degrees for accreditation testing will be discussed, along with ideas for using verification, validation, and accreditation of digital learning objects as a classroom activity. These questions of “Is the model well crafted, is the science right, and is the tool useful?” are fundamentally driven by the process of scientific inquiry and can be used to help students better understand the scientific method.

    Digital imaging technology promises efficient, economical, and fast service for patient care, but the challenges are great in the transition from film to a filmless (digital) environment. This change has a significant impact on the film library's personnel (film librarians) who play a leading roles in storage, classification, and retrieval of images. The objectives of this project were to study film library errors and the usability of a physical computerized system that could not be changed, while developing an intervention to reduce errors and test the usability of the intervention. Cognitive and human factors analysis were used to evaluate human-computer interaction. A workflow analysis was performed to understand the film and digital imaging processes. User and task analyses were applied to account for all behaviors involved in interaction with the system. A heuristic evaluation was used to probe the usability issues in the picture archiving and communication systems (PACS) modules. Simplified paper-based instructions were designed to familiarize the film librarians with the digital system. A usability survey evaluated the effectiveness of the instruction. The user and task analyses indicated that different users faced challenges based on their computer literacy, education, roles, and frequency of use of diagnostic imaging. The workflow analysis showed that the approaches to using the digital library differ among the various departments. The heuristic evaluation of the PACS modules showed the human-computer interface to have usability issues that prevented easy operation. Simplified instructions were designed for operation of the modules. Usability surveys conducted before and after revision of the instructions showed that performance improved. Cognitive and human factor analysis can help film librarians and other users adapt to the filmless system. Use of cognitive science tools will aid in successful transition of the film library from a film environment to a

    The Digital Electronic Guideline Library (DeGeL) is a Web-based framework and a set of distributed tools that facilitate gradual conversion of clinical guidelines from free text, through semi-structured text, to a fully structured, executable representation. Thus, guidelines exist in a hybrid, multiple-format representation The three formats support increasingly sophisticated computational tasks. The tools perform semantic markup, classification, search, and browsing, and support computational modules that we are developing, for run-time application and retrospective quality assessment. We describe the DeGeL architecture and its collaborative-authoring authorization model, which is based on (1) multiple medical-specialty authoring groups, each including a group manager who controls group authorizations, and (2) a hierarchical authorization model based on the different functions involved in the hybrid guideline-specification process. We have implemented the core modules of the DeGeL architecture and demonstrated distributed markup and retrieval using the knowledge roles of two guidelines ontologies (Asbru and GEM). We are currently evaluating several of the DeGeL tools. PMID:14728241

  19. A medical digital library to support scenario and user-tailored information retrieval.

    2000-06-01

    Current large-scale information sources are designed to support general queries and lack the ability to support scenario-specific information navigation, gathering, and presentation. As a result, users are often unable to obtain desired specific information within a well-defined subject area. Today's information systems do not provide efficient content navigation, incremental appropriate matching, or content correlation. We are developing the following innovative technologies to remedy these problems: 1) scenario-based proxies, enabling the gathering and filtering of information customized for users within a pre-defined domain; 2) context-sensitive navigation and matching, providing approximate matching and similarity links when an exact match to a user's request is unavailable; 3) content correlation of documents, creating semantic links between documents and information sources; and 4) user models for customizing retrieved information and result presentation. A digital medical library is currently being constructed using these technologies to provide customized information for the user. The technologies are general in nature and can provide custom and scenario-specific information in many other domains (e.g., crisis management).

    BACKGROUND: Rural physicians need access to digital health sciences libraries (DHSLs) that is easy and reasonably rapid. The goal of this project was to study rural hospitals' access to a DHSL on the Internet, by comparing differing access speeds with differing costs and their acceptability for retrieving text, image, and video information in a DHSL. METHODS: DHSL system response time was measured at three different times during the day over three different types of network connections (T1, Frame Relay, Modem). Text, image, and video information was retrieved. Costs were determined for installation and operation of the different types of network connections. RESULTS: System response times were consistent at the three different testing times for each media type retrieved by each of the three network connection types. System response times for text retrieval met literature standards for all connections. Image retrieval met literature standards for T1 and Frame relay connections. No connection met literature standards for video retrieval. CONCLUSIONS: High speed access to DHSLs is preferable; Frame relay connections provide substantively similar service as T1 connections at less cost. However, access via modem to a DHSL can provide access to the majority of information--text--in a DHSL with an acceptable system response time. PMID:9803301

    BACKGROUND: Rural physicians need access to quality medical information, but accessing information is difficult in rural settings. Digital health sciences libraries (DHSLs) offer the potential to make information more accessible to rural physicians. A telemedicine network was deployed to six rural hospitals in Iowa. Computers were installed allowing access to a DHSL and training sessions were held. The purpose of this study was to examine the barriers to use of a DHSL by rural physicians. METHODS: Approximately one year after deployment of the telemedicine network, physicians were surveyed using a modified critical incident technique. RESULTS: Seventy percent of the eligible physicians responded and 33% had used the DHSL. Primary barriers included insufficient training, being too time consuming to use, and distance of computers from physicians' practice sites. Non-DHSL users cited the difficulty of using the DHSL as their greatest barrier, while DHSL users cited the quality of the information resources. CONCLUSIONS: This study identifies a number of barriers that exist to rural physicians use of a DHSL. Potential solutions to these barriers are discussed. DHSLs will finally reach their potential when they can be delivered by easy to use handheld computers seamlessly integrated into the rural physician's workflow. PMID:9803304

    BACKGROUND: The goal of this prospective, cross-sectional study was to determine the user demographics of a digital health sciences library (DHSL), motives for use, the nature of users information requests, and success rate in finding answers. METHODS: The content of 500 consecutive electronic mail messages (e-mails) submitted to a DHSL were analyzed using a predetermined coding scheme. Data were entered into a database and frequency analysis was performed. RESULTS: The number of information requests from the 500 e-mail messages was 751. The largest sender category was patients and laypersons followed by students, then physicians. Motivations for use were primarily medical advice (42.8%) and patient care (13.8%). E-mail subject areas were mainly medical (61.8%) and technical (20.6%). Answers to information requests were found 54.3% of the time and senders felt the DHSL was valuable (97.8%). CONCLUSIONS: A DHSL is a valuable medical resource. DHSLs must serve the broad information needs of patients and laypersons in addition to health care providers. Developers and managers of DHSLs can use this information to guide future development of DHSL information content and services, as has been done at The University of Iowa. PMID:9803305

    2006-01-01

    Background The North Carolina (NC) Area Health Education Center's (AHEC) Digital Library (ADL) is a web portal designed to meet the information needs of health professionals across the state by pulling together a set of resources from numerous different sources and linking a pool of users to only the resources for which they have eligibility. Although the ADL was designed with the primary purpose of linking health care professionals to a set of licensed resources, the ADL also contains a significant number of links to free resources. These resources are available to any ADL member logging into their ADL account and to guest visitors to the ADL. While there are regular assessments of the subscription resources in the ADL as to utility and frequency of use, up until this point there has been no systematic analysis of the use of the overall set of free resources. It was decided to undertake an examination of the usage of ADL free resources over a 6-month period to analyze the utility of these resources to both ADL members and guests. Methods Each time a resource is accessed through the ADL, it is logged in a table. This study used a SQL query to pull every free resource accessed between November 1, 2005 and April 30, 2006. An additional query also pulled the user information for each free resource accessed. Once the queries of the database were complete, the results were imported into an Excel spreadsheet and analyzed using basic descriptive statistics. Results The vast majority of resource use through the ADL is to licensed resources. There are 2056 free resource URLs in the ADL, to which 1351 were linked out, meaning there was at least one link out to 65% of the free resources. The single most popular free resource was PubMed with 4803 link outs or nearly 20% of the total link outs to free resources. The breakdown of free resource use by different use groups indicates that the highest percentage of use of free resources was by guests followed by institutional

    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.

    With the development of computer technology and practical verification, digital virtual technology has matured and is increasingly being widely applied to cultural heritage protection and research. With this advancement in technology, there is pressing need to simplify heritage-related puzzles. Thus the main question that has increasingly become the most central and fundamental problem in heritage digitalization work is how to choose the "proper technology" that provides support directly, accurately and rapidly for the research, protection and exchange of cultural heritage. Based on the principles of "authenticity" and "completeness" found in the Venice Charter in regards to dealing with cultural heritage; this paper proposes the concept of the component library which facilitates the improvement and efficiency of virtual reconstruction, provides a visual discussion platform for cultural heritage protection, virtual scene construction, accuracy assessment, and multi-space-time exhibition; thereby implementing the spirit of tolerance and respect found in the Nara Document on Authenticity. The paper further aims to illustrate the significance of the Qing dynasty imperial garden architectural component library for cultural heritage study and protection, the principles for virtual library construction, use and maintenance of the library, and classification approaches, and also provide some suggestions about making high quality 3D models and effective means for database integration.

    Arginine catabolic mobile element (ACME), a genomic island consisting of the arc and/or opp3 gene clusters found in staphylococcal species, is related to increased bacterial adaptability to hosts. Staphylococcus epidermidis is considered a major ACME reservoir; however, prevalence and genetic diversity of ACME in coagulase-negative staphylococci (CNS) have not yet been well characterized for clinical isolates in Japan. A total of 271 clinical isolates of CNS in a Japanese hospital were investigated for the presence and genotype of ACME and SCCmec. The prevalence of ACME-arcA was significantly higher (p<0.001) in S. epidermidis (45.8%) than in other CNS species (3.7%). ACME in S. epidermidis isolates (n=87) were differentiated into type I (n=33), variant forms of type I (ΔI, n=26) newly identified in this study, type II (n=6), and type ΔII (n=19). ACME-type ΔI, which were further classified into three subtypes, lacked some genetic components between the arc and opp3 clusters in archetypal type I, whereas the arc and opp3 clusters were intact. The arc cluster exhibited high sequence identity (95.8-100%) to that of type I ACME; in contrast, the opp3 cluster was highly diverse, and showed relatively lower identities (94.8-98.7%) to the identical regions in type I ACME. Twenty-one isolates of ΔI ACME-carrying S. epidermidis possessed SCCmec IVa and belonged to ST5 (clonal complex 2). Phylogenetic analysis revealed that isolates harboring ACME ΔI in this study clustered with previously reported S. epidermidis strains with other lineges, suggesting that S. epidermidis originally had some genetic variations in the opp3 cluster. In summary, ACME type ΔI, a truncated variant of ACME-I, was first identified in S. epidermidis, and revealed to be prevalent in ST5 MRSE clinical isolates with SCCmec IVa.

    Radiology has a recognised role in undergraduate anatomy education. The recent digitalisation of radiology has created new learning opportunities involving techniques such as image labelling, 3D reconstruction, and multiplanar reformatting. An opportunity was identified at the University of Nottingham to create a digital library of normal radiology images as a learner-driven adjunct in anatomy dissection sessions. We describe the process of creating a de novo digital library by sourcing images for presentation at computer workstations. Students' attitudes towards this new resource were assessed using a questionnaire which used a 5 point Likert scale and also offered free text responses. One hundred and forty-one out of 260 students (54%) completed the questionnaire. The most notable findings were: a positive response to the relevance of imaging to the session topics (median score 4), strong agreement that images should be available on the university website (median score 5), and disagreement that enough workstations were available (median score 2). About 24% of respondents suggested independently that images needed more labeling to help with orientation and identification. This first phase of supplying a comprehensive imaging library can be regarded as a success. Increasing availability and incorporating dynamic labeling are well recognized as important design concepts for electronic learning resources and these will be improved in the second phase of delivery as a direct result of student feedback. Hopefully other centers can benefit from this experience and will consider such a venture to be worthwhile.

    Rubber is an engineering material largely used as sealing parts, in form of O-rings, solid gaskets and liquid gaskets, materials applied in liquid state with posterior vulcanization and sealing. Stress relaxation is a rubber characteristic which impacts negatively in such industrial applications (rings and solid gaskets). This work has the purpose to investigate the use of electron beam radiation (EB) as a technology able to decrease the stress relaxation in acrylic rubber (ACM), consequently increasing the sealing capability of this material. ACM samples were irradiated with dose of 100 kGy and 250 kGy, its behavior was comparatively investigated using, dynamic mechanical analysis (DMA) and compression stress relaxation (CSR) experiments. The results obtained by DMA shown an increase of Tg and changes in dynamic mechanical behavior.

The library includes 498 spectra of 444 samples (some samples include a series of grain sizes) measured from approximately 0.2 to 3.0 um . The spectral resolution (Full Width Half Maximum) of the reflectance data is <= 4 nm in the visible (0.2-0.8 um) and <= 10 nm in the NIR (0.8-2.35 um). All spectra were corrected to absolute reflectance using an NIST Halon standard. Library management software lets users search on parameters (e.g. chemical formulae, chemical analyses, purity of samples, mineral groups, etc.) as well as spectral features. Minerals from borate, carbonate, chloride, element, halide, hydroxide, nitrate, oxide, phosphate, sulfate, sulfide, sulfosalt, and the silicate (cyclosilicate, inosilicate, nesosilicate, phyllosilicate, sorosilicate, and tectosilicate) classes are represented. X-Ray and chemical analyses are tabulated for many of the entries, and all samples have been evaluated for spectral purity. The library also contains end and intermediate members for the olivine, garnet, scapolite, montmorillonite, muscovite, jarosite, and alunite solid-solution series. We have included representative spectra of H2O ice, kerogen, ammonium-bearing minerals, rare-earth oxides, desert varnish coatings, kaolinite crystallinity series, kaolinite-smectite series, zeolite series, and an extensive evaporite series. Because of the importance of vegetation to climate-change studies we have include 17 spectra of tree leaves, bushes, and grasses. The library and software are available as a series of U.S.G.S. Open File reports. PC user software is available to convert the binary data to ascii files (a separate U.S.G.S. open file report). Additionally, a binary data files are on line at the U.S.G.S. in Denver for anonymous ftp to users on the Internet. The library search software enables a user to search on documentation parameters as well as spectral features. The

    UAVs are a key element of the Army"s vision for Force Transformation, and are expected to be employed in large numbers per FCS Unit of Action (UoA). This necessitates a multi-UAV level of autonomous collaboration behavior capability that meets RSTA and other mission needs of FCS UoAs. Autonomous Collaborative Mission Systems (ACMS) is a scalable architecture and behavior planning / collaborative approach to achieve this level of capability. The architecture is modular and the modules may be run in different locations/platforms to accommodate the constraints of available hardware, processing resources and mission needs. The Mission Management Module determines the role of member autonomous entities by employing collaboration mechanisms (e.g., market-based, etc.), the individual Entity Management Modules work with the Mission Manager in determining the role and task of the entity, the individual Entity Execution Modules monitor task execution and platform navigation and sensor control, and the World Model Module hosts local and global versions of the environment and the Common Operating Picture (COP). The modules and uniform interfaces provide a consistent and platform-independent baseline mission collaboration mechanism and signaling protocol across different platforms. Further, the modular design allows flexible and convenient addition of new autonomous collaborative behaviors to the ACMS through: adding new behavioral templates in the Mission Planner component, adding new components in appropriate ACMS modules to provide new mission specific functionality, adding or modifying constraints or parameters to the existing components, or any combination of these. We describe the ACMS architecture, its main features, current development status and future plans for simulations in this report.

  20. High-throughput characterization of stresses in thin film materials libraries using Si cantilever array wafers and digital holographic microscopy.

    2011-06-01

    We report the development of an advanced high-throughput stress characterization method for thin film materials libraries sputter-deposited on micro-machined cantilever arrays consisting of around 1500 cantilevers on 4-inch silicon-on-insulator wafers. A low-cost custom-designed digital holographic microscope (DHM) is employed to simultaneously monitor the thin film thickness, the surface topography and the curvature of each of the cantilevers before and after deposition. The variation in stress state across the thin film materials library is then calculated by Stoney's equation based on the obtained radii of curvature of the cantilevers and film thicknesses. DHM with nanometer-scale out-of-plane resolution allows stress measurements in a wide range, at least from several MPa to several GPa. By using an automatic x-y translation stage, the local stresses within a 4-inch materials library are mapped with high accuracy within 10 min. The speed of measurement is greatly improved compared with the prior laser scanning approach that needs more than an hour of measuring time. A high-throughput stress measurement of an as-deposited Fe-Pd-W materials library was evaluated for demonstration. The fast characterization method is expected to accelerate the development of (functional) thin films, e.g., (magnetic) shape memory materials, whose functionality is greatly stress dependent.

  6. Data entry module and manuals for the Land Treatment Digital Library

    USGS Publications Warehouse

    Welty, Justin L.; Pilliod, David S.

    2013-01-01

    Across the country, public land managers make decisions each year that influence landscapes and ecosystems within their jurisdictions. Many of these decisions involve vegetation manipulations, which often are referred to as land treatments. These treatments include removal or alteration of plant biomass, seeding of burned areas, application of herbicides, and other activities. Data documenting these land treatments usually are stored at local management offices in various formats. Therefore, anyone interested in the types and effects of land treatments across multiple jurisdictions must first assemble the information, which can be difficult if data discovery and organization involve multiple local offices. A centralized system for storing and accessing the data helps inform land managers when making policy and management considerations and assists scientists in developing sampling designs and studies. The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey (USGS) as a comprehensive database incorporating tabular data, documentation, photographs, and spatial data about land treatments in a single system. It was developed over a period of several years and refined based on feedback from partner agencies and stakeholders. Currently, Bureau of Land Management (BLM) land treatment data are being entered by USGS personnel as part of a memorandum of understanding between the USGS and BLM. The LTDL has a website maintained by the USGS Forest and Rangeland Ecosystem Science Center where LTDL data can be viewed http://ltdl.wr.usgs.gov/. The resources and information provided in this data series allow other agencies, organizations, and individuals to download an empty, stand-alone LTDL database to individual or networked computers. Data entered in these databases may be submitted to the USGS for possible inclusion in the online LTDL. Multiple computer programs are used to accomplish the objective of the LTDL.

    2005-05-01

    Designed as an pilot project to assess the scientific and pedagogical quality of selected digital resources in the Digital Library for Earth System Education (DLESE), the Climate Change Collection is thematic collection of digital resources relating to the topic of global climate change. Developed through the collaborative efforts of an interdisciplinary review team made up of professionals from the fields of climate research, geoscience education, cognitive psychology, and evaluation, the findings of the project suggest that the user needs of the reviewers should be considered in any review process, that there is inherent value in the collaboration of scientists, teachers and related fields in determining the quality of particular resources, and that the process of preparing for and conducting such reviews and annotations is time-consuming and challenging. Drawing from the experience of prior collection development efforts associated with DLESE, including the Community Review System and the Digital Water Education Library, the Climate Change Collection was developed during the Fall of 2004 and Winter of 2005. Through a series of monthly meetings with the review team facilitated by the Principal Investigator acting as Editor for the collection, and assisted by an online workspace known as a SWIKI, the Climate Change Collection was designed as an experiment in streamlined collection development that may help inform future digital library review and collection-building efforts. The initial meetings focused on training the reviewers, setting context for the review process, and discussing the perspectives of the various participants in the review team. Each participant received a stipend for their involvement in the process. A rubric "scorecard" was developed, tested, and fine-tuned by the review team with a focus primarily on scientific accuracy and the potential for effective use in the classroom.

  9. Towards better digital pathology workflows: programming libraries for high-speed sharpness assessment of Whole Slide Images

    PubMed Central

    2014-01-01

    Background Since microscopic slides can now be automatically digitized and integrated in the clinical workflow, quality assessment of Whole Slide Images (WSI) has become a crucial issue. We present a no-reference quality assessment method that has been thoroughly tested since 2010 and is under implementation in multiple sites, both public university-hospitals and private entities. It is part of the FlexMIm R&D project which aims to improve the global workflow of digital pathology. For these uses, we have developed two programming libraries, in Java and Python, which can be integrated in various types of WSI acquisition systems, viewers and image analysis tools. Methods Development and testing have been carried out on a MacBook Pro i7 and on a bi-Xeon 2.7GHz server. Libraries implementing the blur assessment method have been developed in Java, Python, PHP5 and MySQL5. For web applications, JavaScript, Ajax, JSON and Sockets were also used, as well as the Google Maps API. Aperio SVS files were converted into the Google Maps format using VIPS and Openslide libraries. Results We designed the Java library as a Service Provider Interface (SPI), extendable by third parties. Analysis is computed in real-time (3 billion pixels per minute). Tests were made on 5000 single images, 200 NDPI WSI, 100 Aperio SVS WSI converted to the Google Maps format. Conclusions Applications based on our method and libraries can be used upstream, as calibration and quality control tool for the WSI acquisition systems, or as tools to reacquire tiles while the WSI is being scanned. They can also be used downstream to reacquire the complete slides that are below the quality threshold for surgical pathology analysis. WSI may also be displayed in a smarter way by sending and displaying the regions of highest quality before other regions. Such quality assessment scores could be integrated as WSI's metadata shared in clinical, research or teaching contexts, for a more efficient medical informatics

    Nelson, Michael L.

    1997-01-01

    Our objective was to study the feasibility of extending the Dienst protocol to enable a multi-discipline, multi-format digital library. We implemented two new technologies: cluster functionality and publishing buckets. We have designed a possible implementation of clusters and buckets, and have prototyped some aspects of the resultant digital library. Currently, digital libraries are segregated by the disciplines they serve (computer science, aeronautics, etc.), and by the format of their holdings (reports, software, datasets, etc.). NCSTRL+ is a multi-discipline, multi-format digital library (DL) prototype created to explore the feasibility of the design and implementation issues involved with created a unified, canonical scientific and technical information (STI) DL. NCSTRL+ is based on the Networked Computer Science Technical Report Library (NCSTRL), a World Wide Web (WWW) accessible DL that provides access to over 80 university departments and laboratories. We have extended the Dienst protocol (version 4.1.8), the protocol underlying NCSTRL, to provide the ability to cluster independent collections into a logically centralized DL based upon subject category classification, type of organization, and genre of material. The concept of buckets provides a mechanism for publishing and managing logically linked entities with multiple data formats.

  11. Final report on a pilot academic e-books project at Keio University Libraries : Potential for the scholarly use of digitized academic books

    NASA Astrophysics Data System (ADS)

    Shimada, Takashi

    This article reports on the results and significance of a pilot academic e-books project carried out at the Keio University Libraries for fiscal 2010 to 2012 to assess the viability of a new model of the libraries providing all the campuses with accesses to Japanese academic books digitized jointly with academic publishers and cooperative firms. It focuses on the experimental use of digitized books, highlighting the students’ attitudes and expectations towards e-books as found from surveys. Some major findings include the following. Users have a strong demand for digitized readings that are rather lookup-oriented than learning-oriented, with greater value placed on the functionalities of federated full-text searching, reading on a screen, and accessing the desired chapter direct from table of contents. They also want an online space in which to manage different forms of digitized learning resources. We investigated the potential of e-books and new type of textbooks as educational infrastructures based on the results of experiment. Japan’s university libraries should need to engage actively in the mass digitization of academic books to be adaptive to the change in the ways research, study and teaching are conducted. We plan to start a joint experiment with other university libraries to develop a practical model for the use of e-books.

    Background The Norwegian Electronic Health Library (The Library) is a website for health personnel. Most of the content is also open to the public. Usage statistics have risen sharply in the years 2010-2013. Objective We wanted to find out whether the rise was caused by health personnel, the general public, or other factors. Methods Since we lacked direct information, we had to use proxy data to shed light on our questions. We applied mixed methods (database of registered users, user survey, usage statistics, and statistics from suppliers), and triangulated between them. Results Health personnel were our largest user group, but The Library was also accessed by students, patients, and other groups. Content in Norwegian was preferred to English language content. Concise, practical information was preferred to more comprehensive information. Patient leaflets were the most popular information type. Mobile phone visits differed from personal computer visits both in terms of time of day and what kind of information was viewed. Conclusions The Library was used mostly by health personnel, as intended, but our data are inconclusive regarding a possible change in user groups. There was a large degree of consistency in results when using different investigation methods. The survey points toward health personnel being the largest user group, and the usage statistics show that patient leaflets are the most popular content, being viewed by both health personnel and patients.

    2005-01-01

    Baptist Hospital of Miami has been honoring its staff authors annually during National Library Week since 1979, at the time the library was relocated. Upon "doing the math" and realizing that twenty-five years had passed, a special event was planned to celebrate the occasion in 2004. A merger of four hospitals in 1995 to form Baptist Health South Florida, and an addition of a fifth hospital in 2003 added into the complexity of these publications. Organizing the event led to the conclusion that there had to be a "better way" to manage the publication archive. This paper will include a look back at the event's past, present efforts to develop an archival database, and future plans to make articles available electronically to users, copyright permitting.

    The goal of this study was to complete a literature-based needs assessment with regard to common pediatric problems encountered by pediatric health care providers (PHCPs) and families, and to develop a problem-based pediatric digital library to meet those needs. The needs assessment yielded 65 information sources. Common problems were identified and categorized, and the Internet was manually searched for authoritative Web sites. The created pediatric digital library (www.generalpediatrics.com) used a problem-based interface and was deployed in November 1999. From November 1999 to November 2000, the number of hyperlinks and authoritative Web sites increased 51.1 and 32.2 percent, respectively. Over the same time, visitors increased by 57.3 percent and overall usage increased by 255 percent. A pediatric digital library has been created that begins to bring order to general pediatric resources on the Internet. This pediatric digital library provides current, authoritative, easily accessed pediatric information whenever and wherever the PHCPs and families want assistance.

  17. Towards an Autonomic Cluster Management System (ACMS) with Reflex Autonomicity

    NASA Technical Reports Server (NTRS)

    Truszkowski, Walt; Hinchey, Mike; Sterritt, Roy

    2005-01-01

    Cluster computing, whereby a large number of simple processors or nodes are combined together to apparently function as a single powerful computer, has emerged as a research area in its own right. The approach offers a relatively inexpensive means of providing a fault-tolerant environment and achieving significant computational capabilities for high-performance computing applications. However, the task of manually managing and configuring a cluster quickly becomes daunting as the cluster grows in size. Autonomic computing, with its vision to provide self-management, can potentially solve many of the problems inherent in cluster management. We describe the development of a prototype Autonomic Cluster Management System (ACMS) that exploits autonomic properties in automating cluster management and its evolution to include reflex reactions via pulse monitoring.

  18. Air Traffic Complexity Measurement Environment (ACME): Software User's Guide

    NASA Technical Reports Server (NTRS)

    1996-01-01

    A user's guide for the Air Traffic Complexity Measurement Environment (ACME) software is presented. The ACME consists of two major components, a complexity analysis tool and user interface. The Complexity Analysis Tool (CAT) analyzes complexity off-line, producing data files which may be examined interactively via the Complexity Data Analysis Tool (CDAT). The Complexity Analysis Tool is composed of three independently executing processes that communicate via PVM (Parallel Virtual Machine) and Unix sockets. The Runtime Data Management and Control process (RUNDMC) extracts flight plan and track information from a SAR input file, and sends the information to GARP (Generate Aircraft Routes Process) and CAT (Complexity Analysis Task). GARP in turn generates aircraft trajectories, which are utilized by CAT to calculate sector complexity. CAT writes flight plan, track and complexity data to an output file, which can be examined interactively. The Complexity Data Analysis Tool (CDAT) provides an interactive graphic environment for examining the complexity data produced by the Complexity Analysis Tool (CAT). CDAT can also play back track data extracted from System Analysis Recording (SAR) tapes. The CDAT user interface consists of a primary window, a controls window, and miscellaneous pop-ups. Aircraft track and position data is displayed in the main viewing area of the primary window. The controls window contains miscellaneous control and display items. Complexity data is displayed in pop-up windows. CDAT plays back sector complexity and aircraft track and position data as a function of time. Controls are provided to start and stop playback, adjust the playback rate, and reposition the display to a specified time.

    1993-01-01

    GaAs HBT circuits offer high performance (5-20 GHz) and radiation hardness (500 Mrad) that is attractive for space applications. ACME is a CAD tool specifically developed for HBT circuits. ACME implements a novel physical schematic-capture design technique where designers simultaneously view the structure and physical organization of a circuit. ACME's design interface is similar to schematic capture; however, unlike conventional schematic capture, designers can directly control the physical placement of both function and interconnect at the schematic level. In addition, ACME provides design-time parasitic extraction, complex wire models, and extensions to Multi-Chip Modules (MCM's). A GaAs HBT gate-array and semi-custom circuits have been developed with ACME; several circuits have been fabricated and found to be fully functional .

    The history of veterinary science in South Africa can only be appreciated, studied, researched and passed on to coming generations if historical sources are readily available. In most countries, material and sources with historical value are often difficult to locate, dispersed over a large area and not part of the conventional book and journal literature. The Faculty of Veterinary Science of the University of Pretoria and its library has access to a large collection of historical sources. The collection consists of photographs, photographic slides, documents, proceedings, posters, audio-visual material, postcards and other memorabilia. Other institutions in the country are also approached if relevant sources are identified in their collections. The University of Pretoria's institutional repository, UPSpace, was launched in 2006. This provided the Jotello F. Soga Library with the opportunity to fill the repository with relevant digitised collections of diverse heritage and learning resources that can contribute to the long-term preservation and accessibility of historical veterinary sources. These collections are available for use not only by historians and researchers in South Africa but also elsewhere in Africa and the rest of the world. Important historical collections such as the Arnold Theiler collection, the Jotello F. Soga collection and collections of the Onderstepoort Journal of Veterinary Research and the Journal of the South African Veterinary Association are highlighted. The benefits of an open access digital repository, the importance of collaboration across the veterinary community and other prerequisites for the sustainability of a digitisation project and the importance of metadata to enhance accessibility are covered.

    The realistic representation of key biogeophysical and biogeochemical functions is the fundamental of process-based ecosystem models. Investigating the behavior of those ecosystem functions within real-time model simulation can be a very challenging due to the complex of both model and software structure of an environmental model, such as the Accelerated Climate Model for Energy (ACME) Land Model (ALM). In this research, author will describe the urgent needs and challenges for in-situ data analysis for ALM simulations, and layouts our methods/strategies to meet these challenges. Specifically, an in-situ data analysis framework is designed to allow users interactively observe the biogeophyical and biogeochemical process during ALM simulation. There are two key components in this framework, automatically instrumented ecosystem simulation, in-situ data communication and large-scale data exploratory toolkit. This effort is developed by leveraging several active projects, including scientific unit testing platform, common communication interface and extreme-scale data exploratory toolkit. Authors believe that, based on advanced computing technologies, such as compiler-based software system analysis, automatic code instrumentation, and in-memory data transport, this software system provides not only much needed capability for real-time observation and in-situ data analytics for environmental model simulation, but also the potentials for in-situ model behavior adjustment via simulation steering.

    Segmentation of an image plays an important role in image processing applications. In this paper segmentation of pomegranate magnetic resonance (MR) images has been explored. Pomegranate has healthy nutritional and medicinal properties for which the maturity indices and quality of internal tissues play an important role in the sorting process in which the admissible determination of features mentioned above cannot be easily achieved by human operator. Seeds and soft tissues are the main internal components of pomegranate. For research purposes, such as non-destructive investigation, in order to determine the ripening index and the percentage of seeds in growth period, segmentation of the internal structures should be performed as exactly as possible. In this paper, we present an automatic algorithm to segment the internal structure of pomegranate. Since its intensity of stem and calyx is close to the internal tissues, the stem and calyx pixels are usually labeled to the internal tissues by segmentation algorithm. To solve this problem, first, the fruit shape is extracted from its background using active contour model (ACM). Then stem and calyx are removed using morphological filters. Finally the image is segmented by fuzzy c-means (FCM). The experimental results represent an accuracy of 95.91% in the presence of stem and calyx, while the accuracy of segmentation increases to 97.53% when stem and calyx are first removed by morphological filters.

    From October 1 through September 30, 2016, the Atmospheric Radiation Measurement (ARM) Aerial Facility will deploy the Cessna 206 aircraft over the Southern Great Plains (SGP) site, collecting observations of trace-gas mixing ratios over the ARM’s SGP facility. The aircraft payload includes two Atmospheric Observing Systems, Inc., analyzers for continuous measurements of CO2 and a 12-flask sampler for analysis of carbon cycle gases (CO2, CO, CH4, N2O, 13CO2, 14CO2, carbonyl sulfide, and trace hydrocarbon species, including ethane). The aircraft payload also includes instrumentation for solar/infrared radiation measurements. This research is supported by the U.S. Department of Energy’s ARM Climate Research Facility and Terrestrial Ecosystem Science Program and builds upon previous ARM Airborne Carbon Measurements (ARM-ACME) missions. The goal of these measurements is to improve understanding of 1) the carbon exchange at the SGP site, 2) how CO2 and associated water and energy fluxes influence radiative forcing, convective processes and CO2 concentrations over the SGP site, and 3) how greenhouse gases are transported on continental scales.

    CLIC is a world-wide collaboration to study the next ``terascale'' lepton collider, relying upon a very innovative concept of two-beam-acceleration. This accelerator, currently under study, will be composed of the subsequence of 21000 two-beam-modules. Each module requires more than 300 analogue and digital signals which need to be acquired and controlled in a synchronous way. CLIC-ACM (Acquisition and Control Module) is the 'generic' control and acquisition module developed to accommodate the controls of all these signals for various sub-systems and related specification in term of data bandwidth, triggering and timing synchronization. This paper describes the system architecture with respect to its radiation-tolerance, power consumption and scalability.

    Three different schemes are employed to solve the benchmark problem. The first one is a conventional TVD-MUSCL (Monotone Upwind Schemes for Conservation Laws) scheme. The second scheme is a UNO3-ACM (Uniformly Non-Oscillatory Artificial Compression Method) scheme. The third scheme is an optimized compact finite difference scheme modified by us: the 4th order Runge Kutta time stepping, the 4th order pentadiagonal compact spatial discretization with the maximum resolution characteristics. The problems of category 1 are solved by using the second (UNO3-ACM) and third (Optimized Compact) schemes. The problems of category 2 are solved by using the first (TVD3) and second (UNO3-ACM) schemes. The problem of category 5 is solved by using the first (TVD3) scheme. It can be concluded from the present calculations that the Optimized Compact scheme and the UN03-ACM show good resolutions for category 1 and category 2 respectively.

    The Marine Geoscience Data System (MGDS, www.marine-geo.org) operates an interactive digital data repository and metadata catalog that provides access to a variety of marine geology and geophysical data from throughout the global oceans. Its Marine-Geo Digital Library includes common marine geophysical data types and supporting data and metadata, as well as complementary long-tail data. The Digital Library also includes community data collections and custom data portals for the GeoPRISMS, MARGINS and Ridge2000 programs, for active source reflection data (Academic Seismic Portal), and for marine data acquired by the US Antarctic Program (Antarctic and Southern Ocean Data Portal). Ensuring that these data are discoverable not only through our own interfaces but also through standards-compliant web services is critical for enabling investigators to find data of interest.Over the past two years, MGDS has developed several new RESTful web services that enable programmatic access to metadata and data holdings. These web services are compliant with the EarthCube GeoWS Building Blocks specifications and are currently used to drive our own user interfaces. New web applications have also been deployed to provide a more intuitive user experience for searching, accessing and browsing metadata and data. Our new map-based search interface combines components of the Google Maps API with our web services for dynamic searching and exploration of geospatially constrained data sets. Direct introspection of nearly all data formats for hundreds of thousands of data files curated in the Marine-Geo Digital Library has allowed for precise geographic bounds, which allow geographic searches to an extent not previously possible. All MGDS map interfaces utilize the web services of the Global Multi-Resolution Topography (GMRT) synthesis for displaying global basemap imagery and for dynamically provide depth values at the cursor location.

  13. The acellular matrix (ACM) for bladder tissue engineering: A quantitative magnetic resonance imaging study.

    Bladder acellular matrices (ACMs) derived from natural tissue are gaining increasing attention for their role in tissue engineering and regeneration. Unlike conventional scaffolds based on biodegradable polymers or gels, ACMs possess native biomechanical and many acquired biologic properties. Efforts to optimize ACM-based scaffolds are ongoing and would be greatly assisted by a noninvasive means to characterize scaffold properties and monitor interaction with cells. MRI is well suited to this role, but research with MRI for scaffold characterization has been limited. This study presents initial results from quantitative MRI measurements for bladder ACM characterization and investigates the effects of incorporating hyaluronic acid, a natural biomaterial useful in tissue-engineering and regeneration. Measured MR relaxation times (T(1), T(2)) and diffusion coefficient were consistent with increased water uptake and glycosaminoglycan content observed on biochemistry in hyaluronic acid ACMs. Multicomponent MRI provided greater specificity, with diffusion data showing an acellular environment and T(2) components distinguishing the separate effects of increased glycosaminoglycans and hydration. These results suggest that quantitative MRI may provide useful information on matrix composition and structure, which is valuable in guiding further development using bladder ACMs for organ regeneration and in strategies involving the use of hyaluronic acid.

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

    NASA Astrophysics Data System (ADS)

    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

    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

  7. A Digital Low Dispersion Spectral Library Covering the 3500-7500 Å Region Using the SAAO Radcliffe 1.9 m Telescope's Cassegrain Spectrograph

    NASA Astrophysics Data System (ADS)

    James, David J.

    2013-09-01

    We have created a digital spectral library, using low resolution optical spectra, of photometric and spectral standard stars. The data were acquired using the Cassegrain spectrograph installed on the 1.9 m Radcliffe telescope at the South African Astronomical Observatory. The library consists of optical wavelength (sime3500-7500 Å) spectra for main sequence and giant stars encompassing those most commonly observed in the Galaxy, namely the late-B, A, F, G, K, and early- to mid-M stars. We intend that our standard star spectra will be especially useful for spectral classification of stars in the field and Galactic clusters alike and will have high pedagogic value when included into representative "Introductory Astronomy" or "Stellar Astronomy" curricula for undergraduate astronomy major and minor programs. We exploit the spectral library in order to derive spectral types for 76 optically and X-ray selected members of the young open cluster NGC 6475. Comparison of spectral type, optical and infrared photometric data to theoretical colors derived from spectral type show that the reddening of the cluster is EBV = 0.068 ± 0.012 (1σ = 0.058), a vector consistent with earlier surveys. Our analysis also highlights the utility of such spectra in rejecting cluster nonmembers, thereby allowing the creation of a clean sample of bona fide cluster members for follow-up science observations.

    Debates typically invoke an image of individuals arguing over the merits of opposing viewpoints. However, the term has a softer, more deliberative sense that connotes reflection, discussion, and consideration. The 2009 WebWise conference, titled "Digital Debates," was conducted in this spirit, with panelists and attendees engaged in complex…

    A specialized culture medium termed ciliary neurotrophic factor-treated astrocyte-conditioned medium (CNTF-ACM) allows investigators to assess the peripheral effects of CNTF-induced activated astrocytes upon cultured neurons. CNTF-ACM has been shown to upregulate neuronal L-type calcium channel current activity, which has been previously linked to changes in mitochondrial respiration and oxidative stress. Therefore, the aim of this study was to evaluate CNTF-ACM's effects upon mitochondrial respiration and oxidative stress in rat cortical neurons. Cortical neurons, CNTF-ACM, and untreated control astrocyte-conditioned medium (UC-ACM) were prepared from neonatal Sprague-Dawley rat cortical tissue. Neurons were cultured in either CNTF-ACM or UC-ACM for a 48-h period. Changes in the following parameters before and after treatment with the L-type calcium channel blocker isradipine were assessed: (i) intracellular calcium levels, (ii) mitochondrial membrane potential (ΔΨm), (iii) oxygen consumption rate (OCR) and adenosine triphosphate (ATP) formation, (iv) intracellular nitric oxide (NO) levels, (v) mitochondrial reactive oxygen species (ROS) production, and (vi) susceptibility to the mitochondrial complex I toxin rotenone. CNTF-ACM neurons displayed the following significant changes relative to UC-ACM neurons: (i) increased intracellular calcium levels (p < 0.05), (ii) elevation in ΔΨm (p < 0.05), (iii) increased OCR and ATP formation (p < 0.05), (iv) increased intracellular NO levels (p < 0.05), (v) increased mitochondrial ROS production (p < 0.05), and (vi) increased susceptibility to rotenone (p < 0.05). Treatment with isradipine was able to partially rescue these negative effects of CNTF-ACM (p < 0.05). CNTF-ACM promotes mitochondrial respiration and oxidative stress in cortical neurons through elevating L-type calcium channel activity. PMID:27514537

  15. Forensic examination of ink by high-performance thin layer chromatography--the United States Secret Service Digital Ink Library.

    Forensic examinations of ink have been performed since the beginning of the 20th century. Since the 1960s, the International Ink Library, maintained by the United States Secret Service, has supported those analyses. Until 2009, the search and identification of inks were essentially performed manually. This paper describes the results of a project designed to improve ink samples' analytical and search processes. The project focused on the development of improved standardization procedures to ensure the best possible reproducibility between analyses run on different HPTLC plates. The successful implementation of this new calibration method enabled the development of mathematical algorithms and of a software package to complement the existing ink library. PMID:21196010

  17. An audience-channel-message-evaluation (ACME) framework for health communication campaigns.

    Recent reviews of the literature have indicated that a number of health communication campaigns continue to fail to adhere to principles of effective campaign design. The lack of an integrated, organizing framework for the design, implementation, and evaluation of health communication campaigns may contribute to this state of affairs. The current article introduces an audience-channel-message-evaluation (ACME) framework that organizes the major principles of health campaign design, implementation, and evaluation. ACME also explicates the relationships and linkages between the varying principles. Insights from ACME include the following: The choice of audience segment(s) to focus on in a campaign affects all other campaign design choices, including message strategy and channel/component options. Although channel selection influences options for message design, choice of message design also influences channel options. Evaluation should not be thought of as a separate activity, but rather should be infused and integrated throughout the campaign design and implementation process, including formative, process, and outcome evaluation activities. Overall, health communication campaigns that adhere to this integrated set of principles of effective campaign design will have a greater chance of success than those using principles idiosyncratically. These design, implementation, and evaluation principles are embodied in the ACME framework.
