ABSTRACT

The BROOM system was developed to collect, manage and analyze information from bioterrorist attacks on strategic buildings. GIS features help decision-makers and analysts rapidly assess the current status of contaminated facilities and develop optimized cleanup strategies. BROOM consists of networked server, desktop and PDA components. PDAs are deployed to collect samples of suspected bioagents, such as anthrax. Novel geostatistical methods are used to generate contaminant maps and define optimum locations for subsequent sampling. Efficiency and accuracy gains witnessed in field tests show that GIS technology can play a vital role in visualizing, managing and analyzing data from bioterrorism incidents  相似文献

Abstract

Purpose: This study was conducted to investigate the use of web-based information services in university libraries in Kerala, India.

Design/methodology/approach: A survey method was used for the collection of data. The questionnaire method was used to collect data for the study. The study was conducted among the research scholars of four selected universities in Kerala, India.

Findings: This study has analyzed the services and resources in the libraries which are provided through the medium of the internet and also the usage patterns of web information services by the scholars of the selected universities. The analysis reveals that most of the university libraries have implemented web-based information services. However, the extent of usage is not to the expected level and this is due to the lack of sufficient awareness about the usage methods of web resources and services. With the help of proper user education and training programs, the present situation can be ameliorated. The findings of this study can be helpful to the authorities to improve the services in the libraries.

Originality/value: Proper use of library resources is essential for scholars to bring forth productive research outputs. This study provides recommendations for enhancing web-based services in university libraries in Kerala to provide better services to the users.  相似文献

Abstract

Geographic Information Systems (GIS) as part of the academic library is central on the campus and succeeds with collaboration—in the library, across campus, in the community and region, throughout the state, and at the national level. The integrated components of GIS—hardware, software, data, people, and methods—provide a framework for collaboration. Initiated in 2001, the Geographic Information Systems & Maps Program at the University of Arkansas (UA) Libraries resulted from and developed through collaborative opportunities. The program, which is primarily web based, incorporates locally developed yet nationally recognized resources including Starting the Hunt—a guide to geospatial data on the Web—and GeoStor—a statewide, comprehensive and seamless geospatial data warehouse and delivery system. A model incorporating spheres of collaboration describes the nature and benefits of collaboration at the five different levels, as experienced in the UA Libraries. The model can guide other libraries proactively seeking opportunities of collaboration, in order to develop resources and services for a successful GIS program.  相似文献

ABSTRACT

Working collaboratively, a scholarly resources librarian and a subject liaison librarian at a small, public liberal arts college have created a GIS story mapping workshop for fellow information professionals. Using GIS, the librarians are bridging the gap between humanities and sciences in a liberal arts environment. The librarians' experience of being introduced to GIS and creating training for others enabled them to support their library's data services and digital scholarship initiatives. By helping connect the humanities with science and technology using story maps, librarians can create a neutral environment for learners to conduct interdisciplinary research and develop spatial literacy.  相似文献

Abstract

Internet access and use of georeferenced public health information for GIS application will be an important and exciting development for the nation's Department of Health and Human Services and other health agencies in this new millennium. Technological progress towards public health geospatial data integration, analysis, and visualization of space-time events using the Web portends eventual robust use of GIS by public health and other sectors of the economy. Increasing Web resources from distributed spatial data portals and global geospatial libraries, and a growing suite of Web integration tools, will provide new opportunities to advance disease surveillance, control and prevention, and insure public access and community empowerment in public health decision making. Emerging supercomputing, data mining, and compression and transmission technologies will play increasingly critical roles in national emergency, catastrophic planning and response, and risk management. Web-enabled public health GIS will be guided by Federal Geographic Data Committee spatial metadata, OpenGIS Web interoperability, and GML/XML geospatial Web content standards. Public health will become a responsive and integral part of rhe National Spatial Data Infrastructure.  相似文献

Abstract

Users of geographic data may not be able to afford to purchase and implement a dataset that does not finally meet their needs. Therefore, metadata has a very important role in the information supply environment of geographic data. The development of national/local spatial data infrastructures recognizes the importance of metadata, as do the digital libraries providing spatial data.

The new ISO 19115:2003 standard of metadata for geographic information is introduced briefly. In particular, geographic information can be made available as digital maps (or images) that are meant for visual use, or as datasets meant for computational use. Metadata for digital maps is closely related to the metadata elements for conventional maps and can be enhanced by providing a sample map with the data. The case of computational use of geographic data is more complex. There are several details that may appear crucial when determining the fitness of data for an intended use. Understanding the importance of the crucial factors in each use case requires professional skills from the users of metadata.  相似文献

ABSTRACT

This study explores the current status and features of Pakistan's academic library Web sites. A checklist describing features and content was prepared based on a review of the literature related to academic libraries’ Web sites. Then, all 85 library Web sites of Pakistani universities and degree-awarding institutions recognized by the Higher Education Commission (HEC) of Pakistan were surveyed and analyzed using the checklist. Interviews with library professionals were conducted to learn more about the problems and issues with building and maintaining library Web sites. Results indicate that Pakistani academic library Web sites have effective features such as contrasting color schemes, easily readable text, minimal use of horizontal scrolling, and English-language text. Staff information, OPACs, and navigation features are also widely found on the Web sites. Features found less frequently include the use of Web 2.0 technologies, Web site aid tools, information about library buildings, and general library information. By offering information about the status of Pakistani academic library Web sites, the study can serve as a foundation for discussion between libraries and other parts of the university, as well as a benchmark for evaluating the progress of academic library Web sites in Pakistan  相似文献

ABSTRACT

In the past decade, academic libraries have struggled with the design of an effective library home page. Since librarians' mental models of information architecture differ from those of their patrons, usability assessments are necessary in designing a user-centered home page. This study details a usability sequence of card sort and paper and online survey methods conducted at the Auraria Library, which serves the University of Colorado Denver, the Metropolitan State College of Denver, and the Community College of Denver. The three top complaints about the existing Web page included information overload, lack of visual cues and guidance, and difficulty getting to what students knew was the heart of the library's Web page: online resources. Using qualitative and quantitative data from the card sorting sessions, the Web librarian, under the direction of the Web Advisory Committee, was able to create a more user-centered home page. Unique to this study are the use of undergraduate students in creating test instruments and a means of gathering information about what students value most in their library's home page.  相似文献

The United States National Library of Medicine (NLM) TOXNET® databases <http://toxnet.nlm.nih.gov> provide broad coverage of environmental health information covering a wide variety of topics, including access to the U.S. Environment Protection Agency (EPA)'s Toxics Release Inventory (TRI) data. The NLM web-based geographic information system (GIS), TOXMAP® <http://toxmap.nlm.nih.gov/>, provides interactive maps which show where TRI chemicals are released into the environment and links to TOXNET for information about these chemicals. TOXMAP also displays locations of Superfund sites on the EPA National Priority List, as well as information about the chemical contaminants at these sites. This column focuses on a new version of TOXMAP which brings it up to date with current web GIS technologies and user expectations.  相似文献

Objective:This study was intended to (1) provide clinical trial data-sharing platform designers with insight into users'' experiences when attempting to evaluate and access datasets, (2) spark conversations about improving the transparency and discoverability of clinical trial data, and (3) provide a partial view of the current information-sharing landscape for clinical trials.Methods:We evaluated preview information provided for 10 datasets in each of 7 clinical trial data-sharing platforms between February and April 2019. Specifically, we evaluated the platforms in terms of the extent to which we found (1) preview information about the dataset, (2) trial information on ClinicalTrials.gov and other external websites, and (3) evidence of the existence of trial protocols and data dictionaries.Results:All seven platforms provided data previews. Three platforms provided information on data file format (e.g., CSV, SAS file). Three allowed batch downloads of datasets (i.e., downloading multiple datasets with a single request), whereas four required separate requests for each dataset. All but one platform linked to ClinicalTrials.gov records, but only one platform had ClinicalTrails.gov records that linked back to the platform. Three platforms consistently linked to external websites and primary publications. Four platforms provided evidence of the presence of a protocol, and six platforms provided evidence of the presence of data dictionaries.Conclusions:More work is needed to improve the discoverability, transparency, and utility of information on clinical trial data-sharing platforms. Increasing the amount of dataset preview information available to users could considerably improve the discoverability and utility of clinical trial data.  相似文献

Summary

As a land-grant research university without a geography or cartography department, Washington State University Libraries present a unique organizational context for the adoption of GIS services. The authors consider the implementation of GIS services at the Washington State University Libraries, particularly at the Holland/New Library, which originated from an ARL/GIS Literacy Grant in 1992. The authors cover the following topics in the development of the service: Historical Background, System Architecture, Project Issues and Service Provision, Reference Services Policies, Current Implementation and Related Campus-Wide Issues, and Future Agenda. The services offered were essentially at a minimum level, that is, only providing limited access to government and commercial geospatial data using Arc View and Landview software. The approach to GIS in reference work has been to view it as a specialized service within a standard reference framework very similar to the computer-mediated searching programs of the past. Future plans for GIS services include shifting from a single desktop workstation to a system-wide network access to spatial data and maintaining a centralized repository for all spatial data whether purchased commercially or developed in-house.  相似文献

Abstract

Public libraries are a source of information and resources for the local community, they also play a role in the use of technologies such as geographic information systems (GIS) in that regard. GIS uses maps as output mediums for displaying demographic or similar information, as well as for spatial comparison or spatially based analysis. This is useful for gaining knowledge as well as for decision making. This article reports research into the awareness and use of GIS-type systems in public library settings in hopes of better understanding the benefits, drawbacks, and limitations to use of systems such as these. Primary findings suggest that there continues to exist limited understanding of the capabilities of GIS technology in public libraries and therefore very little demand for it exists in public librarians and patrons alike.  相似文献

Abstract

Institutional archivists can create finding aid tools for their collections that address timely and specific historical issues, such as connections to slavery profits, to manumission, and to anti-slavery and abolitionism. This article takes as its premise a Yale slavery web site of 2001, which drew some startling conclusions that were new answers to some very old questions about the relationships between slavery and the founders of institutions in the colonial and Revolutionary period. Slavery was ubiquitous in the North and a common thread among the founders of many kinds of institutions, colleges included. Institutional archivists can assist in identifying timely questions about momentous events and cultural issues by drawing attention to available resources, and by finding the answers.  相似文献

ABSTRACT

Government publications contain a wealth of information. In an effort to increase the usage of these important publications, the staff at Bierce Library, University of Akron, use the following strategies to integrate and advertise government publications into the library activities and the community: (1) cataloging the publications so they appear on the local online catalog as well as the statewide catalog, (2) integrating them into the bibliographic instruction program, (3) listing them in pathfinders as sources on various topics, (4) making them a focus of “hot topics” such as health care reform, (5) presenting and promoting special workshops on specialized government databases such as the National Trade Data Bank and GPO Access (using the flyer approach), (6) visiting your Congressional Representative's Office to increase awareness of the information available in Depository Libraries to his/her constituents, (7) discussing these avenues at state groups, (8) including these methods in conferences, and (9) joining forces with other Documents Librarians in the area to create a depository brochure announcing hours, services, and highlights of each depository collection, and making this information available on a web page. The above strategies are generic enough that libraries can easily implement them into their programs.

The effect of these strategies is measured by an increased use of government publications. This can be monitored with circulation statistics and use of electronic products. The results are inconclusive if only circulation statistics are used.  相似文献
