Full Text Available As human resources are important resources in organization, it is important for organizations to use knowledge organization of human resources. Thus managing and sharing knowledge in organizations is so important. Libraries as well service-oriented and knowledge-based organizations, librarians’ contribution of knowledge management is important. The study tries to determine Ferdowsi University of Mashhad librarians’ participation in the process of knowledge sharing by knowledge sharing network analysis method. The application used for social network analysis is UCINET6. Determining the degree of centralization in the network of knowledge sharing can also help to detect factors may influence it. In this study, the degree of centralization in the network of knowledge sharing communicating with the librarians' qualifications and work experiences were tested. It is also determined the degree centralization of the whole of the knowledge sharing network with 26.76% that is not so satisfactory.  The results show that despite the positive relationship between level of education and the centrality of people, the experience no significant relationship. Statistically, there is also no significant difference between men and women in knowledge sharing degrees of librarians in Ferdowsi University of Mashhad. At the end, according to the results of this research some suggestions are given to increase degrees of knowledge sharing of librarians and generally knowledge sharing degree of the network knowledge sharing.

Library Learning: Undergraduate Students’ Informal, Self-directed, and Information Sharing Strategies

Directory of Open Access Journals (Sweden)

Jo Ann Murphy

2014-04-01

Full Text Available A focus group study of fourteen University of Saskatchewan second to fourth year humanities and social science undergraduate students was conducted in the fall of 2011. The purpose of the research was to determine how students learn about library resources and services. Findings indicate that the participants often use a variety of informal, self-directed and information sharing strategies. Seeking help from professors, peers, friends, and family members is a common practice. Convenience, familiarity, and perceived knowledge are key factors that determine who and how these students learn about the library. Formal instruction and seeking assistance from librarians did not resonate for participants as a typical approach for learning about the library. The author suggests that undergraduate students engage in informal learning and information sharing as many ‘adult learners’ do, similar to an employment setting. The library, within the formal educational structure, lends itself to a more informal learning context. The study concludes that libraries must continue to develop resources, services, and innovative programs that support students’ informal learning styles, while also providing formal instruction as part of the undergraduate curriculum ensuring students are exposed early on to core foundational skills that contribute to their success as informal and self-directed learners.

Exploring Information Security and Shared Encrypted Spaces in Libraries

Keith Engwall

2015-07-01

Full Text Available Libraries are sensitive to the need to protect patron data, but may not take measures to protect the data of the library. However, in an increasingly collaborative online environment, the protection of data is a concern that merits attention. As a follow-up to a new patron privacy policy, the Oakland University William Beaumont Medical Library evaluated information security tools for use in day-to-day operations in an attempt to identify ways to protect private information in communication and shared storage, as well as a means to manage passwords in a collaborative team environment. This article provides an overview of encryption measures, outlines the Medical Library’s evaluation of encryption tools, and reflects on the benefits and challenges in their adoption and use.

Fixed Access Network Sharing

Science.gov (United States)

Cornaglia, Bruno; Young, Gavin; Marchetta, Antonio

2015-12-01

Fixed broadband network deployments are moving inexorably to the use of Next Generation Access (NGA) technologies and architectures. These NGA deployments involve building fiber infrastructure increasingly closer to the customer in order to increase the proportion of fiber on the customer's access connection (Fibre-To-The-Home/Building/Door/Cabinet… i.e. FTTx). This increases the speed of services that can be sold and will be increasingly required to meet the demands of new generations of video services as we evolve from HDTV to "Ultra-HD TV" with 4k and 8k lines of video resolution. However, building fiber access networks is a costly endeavor. It requires significant capital in order to cover any significant geographic coverage. Hence many companies are forming partnerships and joint-ventures in order to share the NGA network construction costs. One form of such a partnership involves two companies agreeing to each build to cover a certain geographic area and then "cross-selling" NGA products to each other in order to access customers within their partner's footprint (NGA coverage area). This is tantamount to a bi-lateral wholesale partnership. The concept of Fixed Access Network Sharing (FANS) is to address the possibility of sharing infrastructure with a high degree of flexibility for all network operators involved. By providing greater configuration control over the NGA network infrastructure, the service provider has a greater ability to define the network and hence to define their product capabilities at the active layer. This gives the service provider partners greater product development autonomy plus the ability to differentiate from each other at the active network layer.

ASSESSMENT OF LIBRARY USERS’ FEEDBACK USING MODIFIED MULTILAYER PERCEPTRON NEURAL NETWORKS

Directory of Open Access Journals (Sweden)

K G Nandha Kumar

2017-07-01

Full Text Available An attempt has been made to evaluate the feedbacks of library users of four different libraries by using neural network based data mining techniques. This paper presents the results of a survey of users’ satisfactory level on four different libraries. The survey has been conducted among the users of four libraries of educational institutions of Kovai Medical Center Research and Educational Trust. Data were collected through questionnaires. Artificial neural network based data mining techniques are proposed and applied to assess the libraries in terms of level of satisfaction of users. In order to assess the users’ satisfaction level, two neural network techniques: Modified Multilayer Perceptron Network-Supervised and Modified Multilayer Perceptron Network-Unsupervised are proposed. The proposed techniques are compared with the conventional classification algorithm Multilayer Perceptron Neural Network and found better in overall performance. It is found that the quality of service provided by the libraries is highly good and users are highly satisfied with various aspects of library service. The Arts and Science College Library secured the maximum percent in terms of user satisfaction. This shows that the users’ satisfaction of ASCL is better than the other libraries. This study provides an insight into the actual quality and satisfactory level of users of libraries after proper assessment. It is strongly expected that the results will help library authorities to enhance services and quality in the near future.

Quealy, Angela; Cole, Gary L.; Blech, Richard A.

1993-01-01

The Application Portable Parallel Library (APPL) is a subroutine-based library of communication primitives that is callable from applications written in FORTRAN or C. APPL provides a consistent programmer interface to a variety of distributed and shared-memory multiprocessor MIMD machines. The objective of APPL is to minimize the effort required to move parallel applications from one machine to another, or to a network of homogeneous machines. APPL encompasses many of the message-passing primitives that are currently available on commercial multiprocessor systems. This paper describes APPL (version 2.3.1) and its usage, reports the status of the APPL project, and indicates possible directions for the future. Several applications using APPL are discussed, as well as performance and overhead results.

DOLIB: Distributed Object Library

Energy Technology Data Exchange (ETDEWEB)

D' Azevedo, E.F.

1994-01-01

This report describes the use and implementation of DOLIB (Distributed Object Library), a library of routines that emulates global or virtual shared memory on Intel multiprocessor systems. Access to a distributed global array is through explicit calls to gather and scatter. Advantages of using DOLIB include: dynamic allocation and freeing of huge (gigabyte) distributed arrays, both C and FORTRAN callable interfaces, and the ability to mix shared-memory and message-passing programming models for ease of use and optimal performance. DOLIB is independent of language and compiler extensions and requires no special operating system support. DOLIB also supports automatic caching of read-only data for high performance. The virtual shared memory support provided in DOLIB is well suited for implementing Lagrangian particle tracking techniques. We have also used DOLIB to create DONIO (Distributed Object Network I/O Library), which obtains over a 10-fold improvement in disk I/O performance on the Intel Paragon.

BibliOpass – An Open Library Network in Switzerland

Directory of Open Access Journals (Sweden)

Alexis Rivier

2006-04-01

Full Text Available The idea underlying BibliOpass is very simple: extending borrowers' rights to all libraries participating in the network. As in other countries, users of Swiss libraries are more and more mobile, especially the categories of students, teachers or researchers. Universities and technology institute have become more specialized and less general, aiming to improve their reputation at an international level. Students often need to visit different universities during their studies. BibliOpass supports this trend regarding library use in relation to this new mobility. Strangely, similar projects in other countries are not so frequent: Sconul Research Extra in Great Britain which groups together more than 150 higher education institutions is the best example. Basically, BibliOpass makes it simpler for a borrower to use other libraries. More than 600 libraries throughout the country are at present involved in the BibliOpass network. A patron registered as a ‘normal user’ in his or her main library (called ‘Home library’ may borrow items in any other library (called ‘Guest library’ without needing to obtain a new user card or paying extra fees. The user must observe the rules of the guest library (for example number of items and duration of loan. Items must be returned to their originating library for management reasons. BibliOpass is a new, complementary service to Inter Library Loan (ILL, the traditional way to obtain books from other libraries.

2007-01-01

Full Text Available The Selected French libraries (Bibliotheque nationale de France, Bibliotheque publique d’information, multimedia library of the Cité des sciences et de l’industrie as well as Paris public libraries are presented in the article. France does not have a union catalogue at the national level, therefore libraries use different platforms for shared cataloguing and compile more union catalogues. According to their needs, French libraries join into consortia for the acquisition of electronic resources, which can be either geographically or thematically delimited or formed by the institutions of the same status. The author believes that the Slovenian library network works well considering much smaller budget for culture and higher education in comparison with France. To improve its performance, more funds would have to be allocated and higher reputation of the library profession achieved, comparable to the situation in France. Digitization of resources is the area where the Slovenian librarianship lags most behind the French one.

Count Your Calories and Share Them: Health Benefits of Sharing mHealth Information on Social Networking Sites.

Science.gov (United States)

Oeldorf-Hirsch, Anne; High, Andrew C; Christensen, John L

2018-04-23

This study investigates the relationship between sharing tracked mobile health (mHealth) information online, supportive communication, feedback, and health behavior. Based on the Integrated Theory of mHealth, our model asserts that sharing tracked health information on social networking sites benefits users' perceptions of their health because of the supportive communication they gain from members of their online social networks and that the amount of feedback people receive moderates these associations. Users of mHealth apps (N = 511) completed an online survey, and results revealed that both sharing tracked health information and receiving feedback from an online social network were positively associated with supportive communication. Network support both corresponded with improved health behavior and mediated the association between sharing health information and users' health behavior. As users received greater amounts of feedback from their online social networks, however, the association between sharing tracked health information and health behavior decreased. Theoretical implications for sharing tracked health information and practical implications for using mHealth apps are discussed.

Shared protection based virtual network mapping in space division multiplexing optical networks

Science.gov (United States)

Zhang, Huibin; Wang, Wei; Zhao, Yongli; Zhang, Jie

2018-05-01

Space Division Multiplexing (SDM) has been introduced to improve the capacity of optical networks. In SDM optical networks, there are multiple cores/modes in each fiber link, and spectrum resources are multiplexed in both frequency and core/modes dimensions. Enabled by network virtualization technology, one SDM optical network substrate can be shared by several virtual networks operators. Similar with point-to-point connection services, virtual networks (VN) also need certain survivability to guard against network failures. Based on customers' heterogeneous requirements on the survivability of their virtual networks, this paper studies the shared protection based VN mapping problem and proposes a Minimum Free Frequency Slots (MFFS) mapping algorithm to improve spectrum efficiency. Simulation results show that the proposed algorithm can optimize SDM optical networks significantly in terms of blocking probability and spectrum utilization.

In our scheme, when a user needs to share data with others in the same area, the source node and all the intermediate nodes need to perform secure network coding operation before forwarding the received data. This process continues until all the mobile devices in the networks successfully recover the original file. The experimental results show that secure network coding is very feasible and suitable for such file sharing. Moreover, the sharing efficiency and security outperform traditional replication-based sharing scheme.

Sharing of information and knowledge among staff in King Abdullah University of Science and Technology (KAUST) library

KAUST Repository

Ramli, Rindra M.

2011-03-01

This paper describes strategies and initiatives undertaken by the King Abdullah University of Science and Technology (KAUST) library in sharing information and knowledge among its staff. KAUST Library adopted several IT platforms to enable staff to contribute, share, collaborate, extract and act upon knowledge in order to serve our users better. They include: Sharepoint and Google Docs. As Duffy (2000) stated, that “success depends on capitalizing on every available resource including what a company knows and how it uses what it knows”. Therefore, to provide value-added services to our community of researchers and academicians, library staff needs to be equipped with the right skills and tools to be able to act upon users’ inquiries and information needs. KAUST library which was opened in Aug 2009 aims to support education and advanced scientific research. With its state of the art learning and information resource center, the library provides instructional assistance and reference services to its research and academic community. With the influx of information coupled the pervasive use of information technology and Web2.0, the library has to grapple with the issue of information overload. It is important to be able to sieve through the rubbles of information to apply the relevant ones during the point of transaction. Based on our experience in using various IT platforms, this paper will share the impacts of such tools. Lessons learnt and future directions in this area will also be discussed.

Full Text Available Knowledge sharing (KS is a process through which individuals mutually exchange their knowledge with each other and potentially through this process, opportunity for learning new experiences, training and implementing experience, skills and abilities are provided. Therefore, KS is important for various organizations. Accordingly, and because of the importance of KS, this research studies the status of KS and management of public universities’ central libraries websites in Tehran city. Survey method is pilot-descriptive and research tool is a questionnaire. Research community is staffs and stakeholders who are working or commenting on websites. Results of research show that sharing knowledge and influencing factors (including individual factors, organizational and information technology in the study population have a more favorable situation. Findings indicate that among the above three factors, organizational factors than other factors are more barriers on KS. Website management does not have good situation and website management by libraries and good condition, by a library is limited to content part and other parts of technical and structural are managed by the University’s IT Section. Employee’s capabilities and skills that could be effective on working with the website and KS do not have good situation, especially in website’s structural and technical parts and staffs have more skill for working with the content of website. In all, although KS has a good situation among staffs, but KS and management of website is not coherent, dynamic and efficient.

Full Text Available Objective – To determine the prevalence and use of web 2.0 applications in library websites and to determine whether or not their presence enhances the quality of the sites.Design – Content analysis.Setting – Public and academic libraries in North America, Europe, and Asia.Subjects – A total of 120 academic and public library websites in English.Methods – This study identified and selected library websites from academic and public libraries using a combination of directories, ratings reports, and ranking lists from three geographic regions. Over a four-month period in 2009, three coders conducted a three-step content analysis of the selected library websites. This analysis was conducted after having established inter-coder reliability using Cohen’s Kappa and analytic procedure familiarity, using a randomly selected pilot set of 30 library websites. The remaining 90 websites were evenly distributed among the three coders for analysis. They determined whether web 2.0 applications were present, examined how those applications were used, and gave an overall appraisal of website quality. Coders inspected library website links, conducted site searches, used search engines, and searched within major social networking sites to determine the presence of web 2.0 applications. A quality framework classification scheme was used during coding to identify how the web 2.0 applications were being used within library websites. This framework was established around four dimensions of library services: information acquisition (blogs and wikis, information dissemination (Rich Site Summary, or “RSS”, information organization (social tagging, and information sharing (social networking and instant messaging. A five-point Likert scale was also used in concert with a website quality evaluation framework to assess the quality of the library websites. This framework included three aspects of website quality: system quality, information quality, and service

Sagnac secret sharing over telecom fiber networks.

Bogdanski, Jan; Ahrens, Johan; Bourennane, Mohamed

2009-01-19

We report the first Sagnac quantum secret sharing (in three-and four-party implementations) over 1550 nm single mode fiber (SMF) networks, using a single qubit protocol with phase encoding. Our secret sharing experiment has been based on a single qubit protocol, which has opened the door to practical secret sharing implementation over fiber telecom channels and in free-space. The previous quantum secret sharing proposals were based on multiparticle entangled states, difficult in the practical implementation and not scalable. Our experimental data in the three-party implementation show stable (in regards to birefringence drift) quantum secret sharing transmissions at the total Sagnac transmission loop distances of 55-75 km with the quantum bit error rates (QBER) of 2.3-2.4% for the mean photon number micro?= 0.1 and 1.7-2.1% for micro= 0.3. In the four-party case we have achieved quantum secret sharing transmissions at the total Sagnac transmission loop distances of 45-55 km with the quantum bit error rates (QBER) of 3.0-3.7% for the mean photon number micro= 0.1 and 1.8-3.0% for micro?= 0.3. The stability of quantum transmission has been achieved thanks to our new concept for compensation of SMF birefringence effects in Sagnac, based on a polarization control system and a polarization insensitive phase modulator. The measurement results have showed feasibility of quantum secret sharing over telecom fiber networks in Sagnac configuration, using standard fiber telecom components.

An historical overview of the National Network of Libraries of Medicine, 1985-2015.

Speaker, Susan L

2018-04-01

The National Network of Libraries of Medicine (NNLM), established as the Regional Medical Library Program in 1965, has a rich and remarkable history. The network's first twenty years were documented in a detailed 1987 history by Alison Bunting, AHIP, FMLA. This article traces the major trends in the network's development since then: reconceiving the Regional Medical Library staff as a "field force" for developing, marketing, and distributing a growing number of National Library of Medicine (NLM) products and services; subsequent expansion of outreach to health professionals who are unaffiliated with academic medical centers, particularly those in public health; the advent of the Internet during the 1990s, which brought the migration of NLM and NNLM resources and services to the World Wide Web, and a mandate to encourage and facilitate Internet connectivity in the network; and the further expansion of the NLM and NNLM mission to include providing consumer health resources to satisfy growing public demand. The concluding section discusses the many challenges that NNLM staff faced as they transformed the network from a system that served mainly academic medical researchers to a larger, denser organization that offers health information resources to everyone.

Welcome to the National Wetlands Research Center Library: Not Just Another Library-A Special Library

Broussard, Linda

2007-01-01

Libraries are grouped into four major types: public, school, academic, and special. The U.S. Geological Survey's (USGS) National Wetlands Research Center (NWRC) library is classified as a special library because it is sponsored by the Federal government, and the collections focus on a specific subject. The NWRC library is the only USGS library dedicated to wetland science. Library personnel offer expert research services to meet the informational needs of NWRC scientists, managers, and support personnel. The NWRC library participates in international cataloging and resource sharing, which allows libraries from throughout the world to borrow from its collections. This sharing facilitates the research of other governmental agencies, universities, and those interested in the study of wetlands.

2011-01-01

When patients share personal health information with family and friends, their social networks become better equipped to help them through serious health situations. Thus, patients need tools that enable granular control over what personal health information is shared and with whom within social networks. Yet, we know little about how well such tools support patients' complex sharing needs. We report on a lab study in which we examined the transparency of sharing interfaces that display an overview and details of information sharing with network connections in an internet-based personal health information management tool called HealthWeaver. Although participants found the interfaces easy to use and were highly confident in their interpretation of the sharing controls, several participants made errors in determining what information was shared with whom. Our findings point to the critical importance of future work that examines design of usable interfaces that offer transparent granularity in support of patients' complex information sharing practices.

Full Text Available This article describes a generic programmatic method for mapping chemical compound libraries on organism-specific metabolic networks from various databases (KEGG, BioCyc and flat file formats (SBML and Matlab files. We show how this pipeline was successfully applied to decipher the coverage of chemical libraries set up by two metabolomics facilities MetaboHub (French National infrastructure for metabolomics and fluxomics and Glasgow Polyomics on the metabolic networks available in the MetExplore web server. The present generic protocol is designed to formalize and reduce the volume of information transfer between the library and the network database. Matching of metabolites between libraries and metabolic networks is based on InChIs or InChIKeys and therefore requires that these identifiers are specified in both libraries and networks.In addition to providing covering statistics, this pipeline also allows the visualization of mapping results in the context of metabolic networks.In order to achieve this goal we tackled issues on programmatic interaction between two servers, improvement of metabolite annotation in metabolic networks and automatic loading of a mapping in genome scale metabolic network analysis tool MetExplore. It is important to note that this mapping can also be performed on a single or a selection of organisms of interest and is thus not limited to large facilities.

Shared Leadership and Team Creativity: A Social Network Analysis in Engineering Design Teams

Directory of Open Access Journals (Sweden)

Qiong Wu

2016-06-01

Full Text Available This research explores the relationship between shared leadership and creativity in engineering design teams. To do this, a social network perspective was adopted using four measures to assess key elements of shared leadership networks. These are (a network density, (b centralization, (c efficiency and (d strength. Data was collected from a sample of 22 engineering design teams who adopt a shared leadership approach. Our results support previous findings that the density of a shared leadership network is positively related to team creativity. In contrast, we learned that centralization exerts a negative influence on it. Moreover, while we found that there is no evidence to support a positive correlation between efficiency and team creativity, we demonstrate an inverted U-shaped relationship between strength and team creativity in a shared leadership network. These findings are important because they add to the academic debate in the shared leadership area and provide valuable insights for managers.

Sharing resources@CERN

CERN Multimedia

2002-01-01

The library is launching a 'sharing resources@CERN' campaign, aiming to increase the library's utility by including the thousands of books bought by individual groups at CERN. This will improve sharing of information among CERN staff and users. Until now many people were unaware that copies of the same book (or standard, or journal) are often held not only by the library but by different divisions. (Here Eduardo Aldaz, from the PS division, and Isabel Bejar, from the ST division, read their divisional copies of the same book.) The idea behind the library's new sharing resources@CERN' initiative is not at all to collect the books in individual collections at the CERN library, but simply to register them in the Library database. Those not belonging to the library will in principle be unavailable for loan, but should be able to be consulted by anybody at CERN who is interested. "When you need a book urgently and it is not available in the library,' said PS Division engineer Eduardo Aldaz Carroll, it is a sham...

Library usage patterns in the electronic information environment. Electronic journals, Use studies, Libraries, Medical libraries

Full Text Available This paper examines the methodology and results from Web-based surveys of more than 15,000 networked electronic services users in the United States between July 1998 and June 2003 at four academic health sciences libraries and two large main campus libraries serving a variety of disciplines. A statistically valid methodology for administering simultaneous Web-based and print-based surveys using the random moments sampling technique is discussed and implemented. Results from the Web-based surveys showed that at the four academic health sciences libraries, there were approximately four remote networked electronic services users for each in-house user. This ratio was even higher for faculty, staff, and research fellows at the academic health sciences libraries, where more than five remote users for each in-house user were recorded. At the two main libraries, there were approximately 1.3 remote users for each in-house user of electronic information. Sponsored research (grant funded research accounted for approximately 32% of the networked electronic services activity at the health sciences libraries and 16% at the main campus libraries. Sponsored researchers at the health sciences libraries appeared to use networked electronic services most intensively from on-campus, but not from in the library. The purpose of use for networked electronic resources by patrons within the library is different from the purpose of use of those resources by patrons using the resources remotely. The implications of these results on how librarians reach decisions about networked electronic resources and services are discussed.

General-purpose computer networks and resource sharing in ERDA. Volume 3. Remote resource-sharing experience and findings

Energy Technology Data Exchange (ETDEWEB)

1977-07-15

The investigation focused on heterogeneous networks in which a variety of dissimilar computers and operating systems were interconnected nationwide. Homogeneous networks, such as MFE net and SACNET, were not considered since they could not be used for general purpose resource sharing. Issues of privacy and security are of concern in any network activity. However, consideration of privacy and security of sensitive data arise to a much lesser degree in unclassified scientific research than in areas involving personal or proprietary information. Therefore, the existing mechanisms at individual sites for protecting sensitive data were relied on, and no new protection mechanisms to prevent infringement of privacy and security were attempted. Further development of ERDA networking will need to incorporate additional mechanisms to prevent infringement of privacy. The investigation itself furnishes an excellent example of computational resource sharing through a heterogeneous network. More than twenty persons, representing seven ERDA computing sites, made extensive use of both ERDA and non-ERDA computers in coordinating, compiling, and formatting the data which constitute the bulk of this report. Volume 3 analyzes the benefits and barriers encountered in actual resource sharing experience, and provides case histories of typical applications.

Full Text Available Local wisdom possessed by the East Java is a form of culture that represents the identity of the Jawatimuran that does not shared by other regions, but the social dynamics and development of information technology make the knowledge of local wisdom faded and forgotten, so that the next generation remains to know, love and proud in the culture of their own country, then that knowledge must be preserved. The Library and Archives of East Java has organized several workshops. Those workshops are a form of knowledge sharing as an effort to preserve local wisdom of Jawatimuran through writing. The purpose of this study is to evaluate the workshops conducted by The Library and Archives of East Java. The methodology used in this study is a qualitative descriptive method. The results of this study show that knowledge sharing can improve the productivity of the authors and creates integration between authors, publishers and The Library and Archives of East Java in an effort to preserve local wisdom in East Java. The conclusion is that The Library and Archives of East Java should be a bridge for the writers to continue to produce writings based on the local wisdom.

Full Text Available Local wisdom possessed by the East Java is a form of culture that represents the identity of the Jawatimuran that does not shared by other regions, but the social dynamics and development of information technology make the knowledge of local wisdom faded and forgotten, so that the next generation remains to know, love and proud in the culture of their own country, then that knowledge must be preserved. The Library and Archives of East Java has organized several workshops. Those workshops are a form of knowledge sharing as an effort to preserve local wisdom of Jawatimuran through writing. The purpose of this study is to evaluate the workshops conducted by The Library and Archives of East Java. The methodology used in this study is a qualitative descriptive method. The results of this study show that knowledge sharing can improve the productivity of the authors and creates integration between authors, publishers and The Library and Archives of East Java in an effort to preserve local wisdom in East Java. The conclusion is that The Library and Archives of East Java should be a bridge for the writers to continue to produce writings based on the local wisdom.

Secure Peer-to-Peer Networks for Scientific Information Sharing

Science.gov (United States)

Karimabadi, Homa

2012-01-01

The most common means of remote scientific collaboration today includes the trio of e-mail for electronic communication, FTP for file sharing, and personalized Web sites for dissemination of papers and research results. With the growth of broadband Internet, there has been a desire to share large files (movies, files, scientific data files) over the Internet. Email has limits on the size of files that can be attached and transmitted. FTP is often used to share large files, but this requires the user to set up an FTP site for which it is hard to set group privileges, it is not straightforward for everyone, and the content is not searchable. Peer-to-peer technology (P2P), which has been overwhelmingly successful in popular content distribution, is the basis for development of a scientific collaboratory called Scientific Peer Network (SciPerNet). This technology combines social networking with P2P file sharing. SciPerNet will be a standalone application, written in Java and Swing, thus insuring portability to a number of different platforms. Some of the features include user authentication, search capability, seamless integration with a data center, the ability to create groups and social networks, and on-line chat. In contrast to P2P networks such as Gnutella, Bit Torrent, and others, SciPerNet incorporates three design elements that are critical to application of P2P for scientific purposes: User authentication, Data integrity validation, Reliable searching SciPerNet also provides a complementary solution to virtual observatories by enabling distributed collaboration and sharing of downloaded and/or processed data among scientists. This will, in turn, increase scientific returns from NASA missions. As such, SciPerNet can serve a two-fold purpose for NASA: a cost-savings software as well as a productivity tool for scientists working with data from NASA missions.

STAR Library Education Network: a hands-on learning program for libraries and their communities

Science.gov (United States)

Dusenbery, P.

2010-12-01

Science and technology are widely recognized as major drivers of innovation and industry (e.g. Rising above the Gathering Storm, 2006). While the focus for education reform is on school improvement, there is considerable research that supports the role that out-of-school experiences can play in student achievement and public understanding of STEM disciplines. Libraries provide an untapped resource for engaging underserved youth and their families in fostering an appreciation and deeper understanding of science and technology topics. Designed spaces, like libraries, allow lifelong, life-wide, and life-deep learning to take place though the research basis for learning in libraries is not as developed as other informal settings like science centers. The Space Science Institute’s National Center for Interactive Learning (NCIL) in partnership with the American Library Association (ALA), the Lunar and Planetary Institute (LPI), and the National Girls Collaborative Project (NGCP) have received funding from NSF to develop a national education project called the STAR Library Education Network: a hands-on learning program for libraries and their communities (or STAR-Net for short). STAR stands for Science-Technology, Activities and Resources. The overarching goal of the project is to reach underserved youth and their families with informal STEM learning experiences. This project will deepen our knowledge of informal/lifelong learning that takes place in libraries and establish a learning model that can be compared to the more established free-choice learning model for science centers and museums. The project includes the development of two STEM hands-on exhibits on topics that are of interest to library staff and their patrons: Discover Earth and Discover Tech. In addition, the project will produce resources and inquiry-based activities that libraries can use to enrich the exhibit experience. Additional resources will be provided through partnerships with relevant

Full Text Available While scientific models are usually communicated in paper format, the need to reprogram every model by every user results in a huge loss of efforts, time and money, hence lengthening the educational and research developing cycle and loosing the learning experience and expertise gained by every user. We demonstrate a new portal www.imodelit.com that hosts a library of scientific models for electrical engineers in the form of java applets. They are all conformal, informative, with strong input and output filing system. The software design allows a fast developing cycle and it represents a strong infrastructure that can be shared by researchers to develop their own applets to be posted on the library. We aim for a community based library of scientific models that enhances the e-learning process for engineering students.

Distributed generation of shared RSA keys in mobile ad hoc networks

Science.gov (United States)

Liu, Yi-Liang; Huang, Qin; Shen, Ying

2005-12-01

Mobile Ad Hoc Networks is a totally new concept in which mobile nodes are able to communicate together over wireless links in an independent manner, independent of fixed physical infrastructure and centralized administrative infrastructure. However, the nature of Ad Hoc Networks makes them very vulnerable to security threats. Generation and distribution of shared keys for CA (Certification Authority) is challenging for security solution based on distributed PKI(Public-Key Infrastructure)/CA. The solutions that have been proposed in the literature and some related issues are discussed in this paper. The solution of a distributed generation of shared threshold RSA keys for CA is proposed in the present paper. During the process of creating an RSA private key share, every CA node only has its own private security. Distributed arithmetic is used to create the CA's private share locally, and that the requirement of centralized management institution is eliminated. Based on fully considering the Mobile Ad Hoc network's characteristic of self-organization, it avoids the security hidden trouble that comes by holding an all private security share of CA, with which the security and robustness of system is enhanced.

NILDE, Network Inter Library Document Exchange: An Italian Document Delivery System

Brunetti, F.; Gasperini, A.; Mangiaracina, S.

2007-10-01

This poster presents NILDE, a document delivery system supporting the exchange of documents via the internet. The system has been set up by the Central Library of the National Research Council of Bologna (Italy) in order to make use of new internet technology, to promote cooperation between Italian university libraries and research libraries, and to achieve quick response times in satisfying DD requests. The Arcetri Astrophysical Observatory Library was the first astronomical library to join the NILDE project from its earliest days in 2002. Many were the reasons for this choice: automation of the DD processes, security and reliability of the network, creation of usage statistics and reports, reduction of DD System management costs and so on. This work describes the benefits of NILDE and discusses the role of an organized document delivery system as an important tool to cope with the difficult constraints of the publishing market.

Mission Command in the Age of Network-Enabled Operations: Social Network Analysis of Information Sharing and Situation Awareness.

Buchler, Norbou; Fitzhugh, Sean M; Marusich, Laura R; Ungvarsky, Diane M; Lebiere, Christian; Gonzalez, Cleotilde

2016-01-01

A common assumption in organizations is that information sharing improves situation awareness and ultimately organizational effectiveness. The sheer volume and rapid pace of information and communications received and readily accessible through computer networks, however, can overwhelm individuals, resulting in data overload from a combination of diverse data sources, multiple data formats, and large data volumes. The current conceptual framework of network enabled operations (NEO) posits that robust networking and information sharing act as a positive feedback loop resulting in greater situation awareness and mission effectiveness in military operations (Alberts and Garstka, 2004). We test this assumption in a large-scale, 2-week military training exercise. We conducted a social network analysis of email communications among the multi-echelon Mission Command staff (one Division and two sub-ordinate Brigades) and assessed the situational awareness of every individual. Results from our exponential random graph models challenge the aforementioned assumption, as increased email output was associated with lower individual situation awareness. It emerged that higher situation awareness was associated with a lower probability of out-ties, so that broadly sending many messages decreased the likelihood of attaining situation awareness. This challenges the hypothesis that increased information sharing improves situation awareness, at least for those doing the bulk of the sharing. In addition, we observed two trends that reflect a compartmentalizing of networked information sharing as email links were more commonly formed among members of the command staff with both similar functions and levels of situation awareness, than between two individuals with dissimilar functions and levels of situation awareness; both those findings can be interpreted to reflect effects of homophily. Our results have major implications that challenge the current conceptual framework of NEO. In

The Spectrum Sharing in Cognitive Radio Networks Based on Competitive Price Game

Directory of Open Access Journals (Sweden)

Y. B. Li

2012-09-01

Full Text Available The competitive price game model is used to analyze the spectrum sharing problem in the cognitive radio networks, and the spectrum sharing problem with the constraints of available spectrum resource from primary users is further discussed in this paper. The Rockafeller multiplier method is applied to deal with the constraints of available licensed spectrum resource, and the improved profits function is achieved, which can be used to measure the impact of shared spectrum price strategies on the system profit. However, in the competitive spectrum sharing problem of practical cognitive radio network, primary users have to determine price of the shared spectrum without the acknowledgement of the other primary user’s price strategies. Thus a fast gradient iterative calculation method of equilibrium price is proposed, only with acknowledgement of the price strategies of shared spectrum during last cycle. Through the adaptive iteration at the direction with largest gradient of improved profit function, the equilibrium price strategies can be achieved rapidly. It can also avoid the predefinition of adjustment factor according to the parameters of communication system in conventional linear iteration method. Simulation results show that the proposed competitive price spectrum sharing model can be applied in the cognitive radio networks with constraints of available licensed spectrum, and it has better convergence performance.

The first section contained 10 statements for rating shared leadership within their own institutions, which they were asked to rate on an eight-point Likert scale from 1 (strongly agree to 7 (strongly disagree, with 8 as an option for no opinion. The second section used the same scale to rate their levels of agreement with conceptual definitions of shared leadership from Jackson’s Framework. Jackson’s Framework consists of four components for ascertaining levels of shared leadership from both managerial and staff perspectives: accountability, equity, partnership and ownership. The third section invited subjects to provide their own definition of shared leadership. A three-part pretest served to validate the survey instrument. Mean scores were calculated for each statement.Main Results – In the first section, there was the highest overall level of agreement (1.52 with the statement “I am accountable for the decisions within the scope of my responsibility” followed by “I share information with the senior library administration” (1.71. There was the lowest overall level of agreement (3.65 with the statement that “Ideas presented at all levels of staff in the library are equally considered.” In the second section, respondents’ mean scores for Jackson’s definitions of four concepts of shared leadership were 2.62 for ownership

Full Text Available Amid widespread resistance to online social networking tools, their effectiveness in promoting knowledge sharing in a knowledge-driven organisation was demonstrated in the study. Usage patterns, user attitudes and perceptions regarding online social networking technologies as a professional application for knowledge sharing within the workplace were investigated. Self-administered questionnaires were administered to a sample of IBM Global Business Services employees in South Africa. Upon completion of the questionnaire analysis an interview was conducted with the knowledge manager for verification and clarification purposes. The results revealed the respondents' positive attitudes regarding the use of social networking tools for knowledge sharing. The culture of knowledge sharing at IBM and the contribution that social networking tools makes within the company were uncovered. Findings disclosed that the online social networking tools were effective and that management at IBM encourages employees to make more and more use of the tools for knowledge sharing and knowledge creation. The results of this study demonstrate the effectiveness of online social networking tools and serve as encouragement to hesitant organisations to adopt social networking in their business practices.

Networked Memory Project: A Policy Thought Experiment for the Archiving of Social Networks by the Library of Congress of the United States

Directory of Open Access Journals (Sweden)

Chloé S. Georas

2014-07-01

Full Text Available This article explores the challenges posed by an archival interest in the broad palimpsest of daily life left on social networks that are controlled by private corporations. It addresses whether social networks should be archived for the benefit of future generations and proposes a policy thought experiment to help grapple with these questions, namely, the proposal for the formation of the public interest-oriented Networked Memory Project by the Library of Congress for the archiving of social networks. My discussion of the challenges posed by this thought experiment will focus on the U.S. legal framework within which the Library of Congress operates and take Facebook. To the extent that social networks have user-generated contents that range from the highly “private” to “public” as opposed to other networked platforms that contain materials that are considered “public”, the bar for the historical archival of social networks is much higher. Almost every archival effort must contend with the legal hurdle of copyright, but the archiving of social networks must also address how to handle the potentially sensitive nature of materials that are considered “private” from the perspective of the social and legal constructions of privacy. My theoretical exercise of proposing the formation of the Networked Memory Project by the Library of Congress responds to the need to consider the benefits of a public interest-oriented archive of social networks that can counter the drawbacks of the incidental corporate archiving taking place on social networks.

Fuzzy-rule-based Adaptive Resource Control for Information Sharing in P2P Networks

Science.gov (United States)

Wu, Zhengping; Wu, Hao

With more and more peer-to-peer (P2P) technologies available for online collaboration and information sharing, people can launch more and more collaborative work in online social networks with friends, colleagues, and even strangers. Without face-to-face interactions, the question of who can be trusted and then share information with becomes a big concern of a user in these online social networks. This paper introduces an adaptive control service using fuzzy logic in preference definition for P2P information sharing control, and designs a novel decision-making mechanism using formal fuzzy rules and reasoning mechanisms adjusting P2P information sharing status following individual users' preferences. Applications of this adaptive control service into different information sharing environments show that this service can provide a convenient and accurate P2P information sharing control for individual users in P2P networks.

Lee, Sandra Soo-Jin; Vernez, Simone L; Ormond, K E; Granovetter, Mark

2013-10-14

Little is known about how consumers of direct-to-consumer personal genetic services share personal genetic risk information. In an age of ubiquitous online networking and rapid development of social networking tools, understanding how consumers share personal genetic risk assessments is critical in the development of appropriate and effective policies. This exploratory study investigates how consumers share personal genetic information and attitudes towards social networking behaviors. Adult participants aged 23 to 72 years old who purchased direct-to-consumer genetic testing from a personal genomics company were administered a web-based survey regarding their sharing activities and social networking behaviors related to their personal genetic test results. 80 participants completed the survey; of those, 45% shared results on Facebook and 50.9% reported meeting or reconnecting with more than 10 other individuals through the sharing of their personal genetic information. For help interpreting test results, 70.4% turned to Internet websites and online sources, compared to 22.7% who consulted their healthcare providers. Amongst participants, 51.8% reported that they believe the privacy of their personal genetic information would be breached in the future. Consumers actively utilize online social networking tools to help them share and interpret their personal genetic information. These findings suggest a need for careful consideration of policy recommendations in light of the current ambiguity of regulation and oversight of consumer initiated sharing activities.

Libraries Protecting Privacy on Social Media: Sharing without "Oversharing"

Kelley Cotter

2016-11-01

Full Text Available Libraries have increasingly adopted social media as an integral means of connecting with their users. However, social media presents many potential concerns regarding library patron privacy. This article presents the findings from a study of how librarians and library staff perceive and handle issues of patron privacy related to social media marketing in libraries. The study reports the results from a mixed-methods online survey, which used a nonprobability self-selection sampling method to collect responses from individuals employed by libraries, without restrictions on position or library type. Nearly three-quarters of respondents reported working in libraries that have either an official or unofficial social media policy. Approximately 53% of those policies mention patron privacy. The findings suggest that many respondents’ views and practices are influenced by the perception of the library’s physical space and social media presence as public places. The findings also suggest a lack of consensus regarding the extent of the library’s obligation to protect patron privacy on library social media sites and what would constitute a violation of privacy.

Erevik, Eilin K; Torsheim, Torbjørn; Vedaa, Øystein; Andreassen, Cecilie S; Pallesen, Ståle

2017-05-01

The present study aimed to explore students' reports of their sharing of alcohol-related content on different social networking sites (i.e., frequency of sharing and connotations of alcohol-related posts), and to identify indicators of such posting. Students at the four largest institutions for higher education in Bergen, Norway, were invited to participate in an Internet-based survey. The sample size was 11,236 (a 39.4% response rate). The survey included questions about disclosure of alcohol-related content on social networking sites, alcohol use (using the Alcohol Use Disorders Identification Test), personality factors (using the Mini-IPIP), and demographic characteristics. Binary logistic regressions were used to analyze indicators of frequent sharing of alcohol-related content depicting positive and negative aspects of alcohol use. A majority of the students had posted alcohol-related content (71.0%), although few reported having done so frequently. Positive aspects of alcohol use (e.g., enjoyment or social community) were most frequently shared. Young, single, and extroverted students with high alcohol consumption were more likely to report frequent sharing of alcohol-related content. Positive attitudes toward posting alcohol-related content and reports of exposure to such content particularly increased the likelihood of one's own posting of alcohol-related content. Positive aspects of alcohol use seem to be emphasized on social networking sites. Sharing of alcohol-related content is associated with heightened alcohol use, which implies that such sites can be relevant for prevention agents. Social influence from social networking sites, such as exposure to others' alcohol-related content, is associated with one's own sharing of similar content.

The potential of the diverse chemistries present in natural products (NP) for biotechnology and medicine remains untapped because NP databases are not searchable with raw data and the NP community has no way to share data other than in published papers. Although mass spectrometry techniques are well-suited to high-throughput characterization of natural products, there is a pressing need for an infrastructure to enable sharing and curation of data. We present Global Natural Products Social molecular networking (GNPS, http://gnps.ucsd.edu), an open-access knowledge base for community wide organization and sharing of raw, processed or identified tandem mass (MS/MS) spectrometry data. In GNPS crowdsourced curation of freely available community-wide reference MS libraries will underpin improved annotations. Data-driven social-networking should facilitate identification of spectra and foster collaborations. We also introduce the concept of ‘living data’ through continuous reanalysis of deposited data.

Liao, Luhua; Li, Lemin; Wang, Sheng

2006-12-01

We investigate the protection approach for dynamic multicast traffic under shared risk link group (SRLG) constraints in meshed wavelength-division-multiplexing optical networks. We present a shared protection algorithm called dynamic segment shared protection for multicast traffic (DSSPM), which can dynamically adjust the link cost according to the current network state and can establish a primary light-tree as well as corresponding SRLG-disjoint backup segments for a dependable multicast connection. A backup segment can efficiently share the wavelength capacity of its working tree and the common resources of other backup segments based on SRLG-disjoint constraints. The simulation results show that DSSPM not only can protect the multicast sessions against a single-SRLG breakdown, but can make better use of the wavelength resources and also lower the network blocking probability.

Guest editorial - Networked collaboration, sharing and response

Directory of Open Access Journals (Sweden)

Olav Skundberg

2008-11-01

Full Text Available  This issue of Seminar.net contains three articles that were written in connection with a Norwegian e-learning conference titled “Networked collaboration, sharing and response”. The conference was held in Mars 2008 in Trondheim, and the presentations from the conference is available (in norwegian language at http://www.nvu.no. Networked collaboration was chosen as a theme because collaboration is important to achieve learning, according to the social-constructivistic pedagogy that has a strong standing in Norway, but how should this occur on the net? Sharing of content, as in digital learning resources, is a phenomenon with increasing popularity as described in the OECD-report “Giving Knowledge for Free”. But to achieve reuse of content, not only publishing it, it is important with a networked community where the plethora of information can be sorted with relevance to specific topics. Response is about guiding, coaching and tutoring. In what ways may resources and tools be used to move in the direction of solving Bloom’s two sigma problem/challenge? The first article, by Morten Flate Paulsen, shows how cooperative learning can be implemented successfully so that students have optimal individual freedom within online learning communities. The second article, by Carl F. Dons, shows how student teachers can be prepared to deal with pupils who have a wide range of experiences of the digital world. The third and last article, by Kristin Dale, is sharing experiences with multiple choice-tests to give midterm responses to students. In addition, this issue has a commentary article by Rune Krumsvik discussing the need to develop new practices for teachers and students on the background of the digital developments. The conference and articles covers three big themes. It may be difficult to find more important issues, apart from finding money and time to support its development. Olav Skundberg, guest editorAssociate professor

Private Sharing of User Location over Online Social Networks

OpenAIRE

Freudiger, Julien; Neu, Raoul; Hubaux, Jean-Pierre

Online social networks increasingly allow mobile users to share their location with their friends. Much to the detriment of users’ privacy, this also means that social network operators collect users’ lo- cation. Similarly, third parties can learn users’ location from localization and location visualization services. Ideally, third-parties should not be given complete access to users’ location. To protect location privacy, we design and implement a platform-independent solution for users to s...

Full Text Available A longitudinal study of three discrete online public access catalog (OPAC design enhancements examined the possible effects such changes may have on circulation and resource sharing within the automated library consortium environment. Statistical comparisons were made of both circulation and interlibrary loan (ILL figures from the year before enhancement to the year after implementation. Data from sixteen libraries covering a seven-year period were studied in order to determine the degree to which patrons may or may not utilize increasingly broader OPAC ILL options over time. Results indicated that while ILL totals increased significantly after each OPAC enhancement, such gains did not result in significant corresponding changes in total circulation.

Network Analysis of an Emergent Massively Collaborative Creation on Video Sharing Website

Science.gov (United States)

Hamasaki, Masahiro; Takeda, Hideaki; Nishimura, Takuichi

The Web technology enables numerous people to collaborate in creation. We designate it as massively collaborative creation via the Web. As an example of massively collaborative creation, we particularly examine video development on Nico Nico Douga, which is a video sharing website that is popular in Japan. We specifically examine videos on Hatsune Miku, a version of a singing synthesizer application software that has inspired not only song creation but also songwriting, illustration, and video editing. As described herein, creators of interact to create new contents through their social network. In this paper, we analyzed the process of developing thousands of videos based on creators' social networks and investigate relationships among creation activity and social networks. The social network reveals interesting features. Creators generate large and sparse social networks including some centralized communities, and such centralized community's members shared special tags. Different categories of creators have different roles in evolving the network, e.g., songwriters gather more links than other categories, implying that they are triggers to network evolution.

When Sharing Is a Bad Idea: The Effects of Online Social Network Engagement and Sharing Passwords with Friends on Cyberbullying Involvement.

Science.gov (United States)

Meter, Diana J; Bauman, Sheri

2015-08-01

Every day, children and adolescents communicate online via social networking sites (SNSs). They also report sharing passwords with peers and friends, a potentially risky behavior in regard to cyber safety. This longitudinal study tested the hypotheses that social network engagement in multiple settings would predict more cyberbullying involvement over time, and that youth who reported sharing passwords would also experience an increase in cyberbullying involvement. Data were collected at two time points one year apart from 1,272 third through eighth grade students. In line with the first study hypothesis, participating in more online SNSs was associated with increased cyberbullying involvement over time, as well as sharing passwords over time. Cyberbullying involvement at T1 predicted decreases in sharing passwords over time, suggesting that youth become aware of the dangers of sharing passwords as a result of their experience. Sharing passwords at T1 was unrelated to cyberbullying involvement at T2. Although it seems that youth may be learning from their previous mistakes, due to the widespread use of social media and normality of sharing passwords among young people, it is important to continue to educate youth about cyber safety and risky online behavior.

Optimization of communication network topology for navigation sharing among distributed satellites

Science.gov (United States)

Dang, Zhaohui; Zhang, Yulin

2013-01-01

Navigation sharing among distributed satellites is quite important for coordinated motion and collision avoidance. This paper proposes optimization methods of the communication network topology to achieve navigation sharing. The whole communication network constructing by inter-satellite links are considered as a topology graph. The aim of this paper is to find the communication network topology with minimum communication connections' number (MCCN) in different conditions. It has found that the communication capacity and the number of channels are two key parameters affecting the results. The model of MCCN topology for navigation sharing is established and corresponding method is designed. Two main scenarios, viz., homogeneous case and heterogeneous case, are considered. For the homogeneous case where each member has the same communication capacity, it designs a construction method (Algorithm 1) to find the MCCN topology. For the heterogeneous case, it introduces a modified genetic algorithm (Algorithm 2) to find the MCCN topology. When considering the fact that the number of channels is limited, the Algorithm 2 is further modified by adding a penalized term in the fitness function. The effectiveness of these algorithms is all proved in theoretical. Three examples are further tested to illustrate the methods developed in this paper.

Sharing for Health: A Study of Chinese Adolescents' Experiences and Perspectives on Using Social Network Sites to Share Health Information.

Science.gov (United States)

Zhang, Ni; Teti, Michele; Stanfield, Kellie; Campo, Shelly

2017-07-01

This exploratory qualitative study examines Chinese adolescents' health information sharing habits on social network sites. Ten focus group meetings with 76 adolescents, ages 12 to 17 years, were conducted at community-based organizations in Chicago's Chinatown. The research team transcribed the recording and analyzed the transcripts using ATLAS.ti. Chinese adolescents are using different social network sites for various topics of health information including food, physical activity, and so on. Adolescents would share useful and/or interesting health information. Many adolescents raised credibility concerns regarding health information and suggested evaluating the information based on self-experience or intuition, word-of-mouth, or information online. The findings shed lights on future intervention using social network sites to promote health among Chinese adolescents in the United States. Future interventions should provide adolescents with interesting and culturally sensitive health information and educate them to critically evaluate health information on social network sites.

News from the Library: The 'long tail' Library

CERN Multimedia

CERN Library

2012-01-01

"The term 'long tail' has gained popularity in recent times as describing the retailing strategy of selling a large number of unique items with relatively small quantities sold of each usually in addition to selling fewer popular items in large quantities. The long tail was popularized by Chris Anderson, who mentioned Amazon.com, Apple and Yahoo! as examples of businesses applying this strategy." *   If we leave the business environment and move to the world of libraries, we still see this "long tail". Usually, only a small portion of a library's book collection accounts for the majority of its loans. On the other hand, there are a variety of "niche information needs" that might not be met, as libraries cannot afford to build up huge collections of documents available just-in-case. However, the networked environment of today's libraries can offer a solution. Online networks of libraries ca...

Hughes, J. Steven; Crichton, Daniel J.; Mattmann, Chris A.

2009-01-01

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.

Incentive Mechanism for P2P Content Sharing over Heterogenous Access Networks

Science.gov (United States)

Sato, Kenichiro; Hashimoto, Ryo; Yoshino, Makoto; Shinkuma, Ryoichi; Takahashi, Tatsuro

In peer-to-peer (P2P) content sharing, users can share their content by contributing their own resources to one another. However, since there is no incentive for contributing contents or resources to others, users may attempt to obtain content without any contribution. To motivate users to contribute their resources to the service, incentive-rewarding mechanisms have been proposed. On the other hand, emerging wireless technologies, such as IEEE 802.11 wireless local area networks, beyond third generation (B3G) cellular networks and mobile WiMAX, provide high-speed Internet access for wireless users. Using these high-speed wireless access, wireless users can use P2P services and share their content with other wireless users and with fixed users. However, this diversification of access networks makes it difficult to appropriately assign rewards to each user according to their contributions. This is because the cost necessary for contribution is different in different access networks. In this paper, we propose a novel incentive-rewarding mechanism called EMOTIVER that can assign rewards to users appropriately. The proposed mechanism uses an external evaluator and interactive learning agents. We also investigate a way of appropriately controlling rewards based on the system service's quality and managing policy.

[The future of scientific libraries].

Science.gov (United States)

De Fiore, Luca

2013-10-01

"Making predictions is always very difficult, especially about the future". Niels Bohr's quote is very appropriate when looking into the future of libraries. If the Web is now the richest library in the world, it is also the most friendly and therefore the most convenient. The evolution of libraries in the coming years - both traditional and online - will probably depend on their ability to meet the information needs of users: improved ease of use and better reliability of the information. These are objectives that require money and - given the general reduction in budgets - it is not obvious that the results will be achieved. However, there are many promising experiences at the international level that show that the world of libraries is populated by projects and creativity. Traditional or digital, libraries will increasingly present themselves more as a sharing tool than as a repository of information: it is the sharing that translates data into knowledge. In the healthcare field, the integration of online libraries with the epidemiological information systems could favor the fulfillment of unconscious information needs of health personnel; libraries will therefore be a key tool for an integrated answer to the challenge of continuing education in medicine. The Internet is no longer a library but an information ecosystem where the data are transformed into knowledge by sharing and discussion.

Full Text Available Purpose: Regional public libraries were initiated in 2003 to connect professional activities of libraries within regional networks and to ensure coordinated library development in a region in cooperation with the Library System Development Centre at the National and University Library performing a coordinating role. The article analyses the performance of public libraries and their integration in regional library networks in order to find out the level of development of conditions of performance of public libraries.Methodology/approach: Statistical data for the year 2009 were the basis for the overview of library activities of ten library regions with regard to applicable legislation and library standards. The level of regional library activities is compared to the socio-economic situation of statistical regions thus representing a new approach to the presentation of Slovenian’s public libraries’ development.Results: Absolute values indicate better development of nine libraries in the central Slovenia region while relative values offer a totally different picture. Four libraries in the region of Nova Gorica prove the highest level of development.Research limitation: Research is limited to the year 2009 and basic statistical analysis.Originality/practical implications: Findings of the analysis are useful for public libraries to plan their development strategy within a region and for financial bodies to provide for adequate financing for library activities in a specific region. The basic condition for successful public library performance is the even and harmonized development of conditions of performance as recommended by library standards.

Network computing infrastructure to share tools and data in global nuclear energy partnership

International Nuclear Information System (INIS)

Kim, Guehee; Suzuki, Yoshio; Teshima, Naoya

2010-01-01

CCSE/JAEA (Center for Computational Science and e-Systems/Japan Atomic Energy Agency) integrated a prototype system of a network computing infrastructure for sharing tools and data to support the U.S. and Japan collaboration in GNEP (Global Nuclear Energy Partnership). We focused on three technical issues to apply our information process infrastructure, which are accessibility, security, and usability. In designing the prototype system, we integrated and improved both network and Web technologies. For the accessibility issue, we adopted SSL-VPN (Security Socket Layer - Virtual Private Network) technology for the access beyond firewalls. For the security issue, we developed an authentication gateway based on the PKI (Public Key Infrastructure) authentication mechanism to strengthen the security. Also, we set fine access control policy to shared tools and data and used shared key based encryption method to protect tools and data against leakage to third parties. For the usability issue, we chose Web browsers as user interface and developed Web application to provide functions to support sharing tools and data. By using WebDAV (Web-based Distributed Authoring and Versioning) function, users can manipulate shared tools and data through the Windows-like folder environment. We implemented the prototype system in Grid infrastructure for atomic energy research: AEGIS (Atomic Energy Grid Infrastructure) developed by CCSE/JAEA. The prototype system was applied for the trial use in the first period of GNEP. (author)

2007-12-01

Full Text Available This article discusses the key features of a newly developed national data-sharing online network for material environmental corrosion. Written in Java language and based on Oracle database technology, the central database in the network is supported with two unique series of corrosion failure data, both of which were accumulated during a long period of time. The first category of data, provided by national environment corrosion test sites, is corrosion failure data for different materials in typical environments (atmosphere, seawater and soil. The other category is corrosion data in production environments, provided by a variety of firms. This network system enables standardized management of environmental corrosion data, an effective data sharing process, and research and development support for new products and after-sale services. Moreover this network system provides a firm base and data-service platform for the evaluation of project bids, safety, and service life. This article also discusses issues including data quality management and evaluation in the material corrosion data sharing process, access authority of different users, compensation for providers of shared historical data, and finally, the related policy and law legal processes, which are required to protect the intellectual property rights of the database.

To examine the scientific evidence regarding the association between characteristics of social networks of injection drug users (IDUs) and the sharing of drug injection equipment. A search was performed on MEDLINE, EMBASE, BIOSIS, Current Contents, PsycINFO databases and other sources to identify published studies on social networks of IDUs. Papers were selected based on their examination of social network factors in relation to the sharing of syringes and drug preparation equipment (e.g. containers, filters, water). Additional relevant papers were found from the reference list of identified articles. Network correlates of drug equipment sharing are multi-factorial and include structural factors (network size, density, position, turnover), compositional factors (network member characteristics, role and quality of relationships with members) and behavioural factors (injecting norms, patterns of drug use, severity of drug addiction). Factors appear to be related differentially to equipment sharing. Social network characteristics are associated with drug injection risk behaviours and should be considered alongside personal risk behaviours in prevention programmes. Recommendations for future research into the social networks of IDUs are proposed.

To meet the informational needs of health care practitioners and trainees in a four-county rural area of northwestern North Carolina, the eleven-member UNIFOUR Consortium was founded as a two-year experimental project from 1978 to 1980. The consortium has several unique features: (1) it is an organization of institutions, not libraries; (2) it employs its own professional librarian who manages a central library, coordinates consortium programs, and makes regular circuit visits to all affiliated institutions; (3) the central library, where the circuit is based, is a developing community hospital library, not an established academic medical center library; and (4) it is ultimately tied to the Northwest Area Health Education Center and that organization's emerging learning resources network, which includes the Bowman Gray School of Medicine, Library, two other subregional libraries, and the libraries of all member institutions. At the end of the experimental period in 1980, member institutions voted unanimously to continue the program and assume their share of the costs.

Shared "core" areas between the pain and other task-related networks.

Directory of Open Access Journals (Sweden)

Franco Cauda

Full Text Available The idea of a 'pain matrix' specifically devoted to the processing of nociceptive inputs has been challenged. Alternative views now propose that the activity of the primary and secondary somatosensory cortices (SI, SII, the insula and cingulate cortex may be related to a basic defensive system through which significant potentially dangerous events for the body's integrity are detected. By reviewing the role of the SI, SII, the cingulate and the insular cortices in the perception of nociceptive and tactile stimuli, in attentional, emotional and reward tasks, and in interoception and memory, we found that all these task-related networks overlap in the dorsal anterior cingulate cortex, the anterior insula and the dorsal medial thalamus. A thorough analysis revealed that the 'pain-related' network shares important functional similarities with both somatomotor-somatosensory networks and emotional-interoceptive ones. We suggest that these shared areas constitute the central part of an adaptive control system involved in the processing and integration of salient information coming both from external and internal sources. These areas are activated in almost all fMRI tasks and have been indicated to play a pivotal role in switching between externally directed and internally directed brain networks.

2011-09-01

Full Text Available Social computing and online communities are changing the fundamental way people share information and communicate with each other. Social computing focuses on how users may have more autonomy to express their ideas and participate in social exchanges in various ways, one of which may be peer-to-peer (P2P file sharing. Given the greater risk of opportunistic behavior by malicious or criminal communities in P2P networks, it is crucial to understand the factors that affect individual’s use of P2P file sharing software. In this paper, we develop and empirically test a research model that includes trust beliefs and perceived risks as two major antecedent beliefs to the usage intention. Six trust antecedents are assessed including knowledge-based trust, cognitive trust, and both organizational and peer-network factors of institutional trust. Our preliminary results show general support for the model and offer some important implications for software vendors in P2P sharing industry and regulatory bodies.

Generalized Load Sharing for Homogeneous Networks of Distributed Environment

Directory of Open Access Journals (Sweden)

A. Satheesh

2008-01-01

Full Text Available We propose a method for job migration policies by considering effective usage of global memory in addition to CPU load sharing in distributed systems. When a node is identified for lacking sufficient memory space to serve jobs, one or more jobs of the node will be migrated to remote nodes with low memory allocations. If the memory space is sufficiently large, the jobs will be scheduled by a CPU-based load sharing policy. Following the principle of sharing both CPU and memory resources, we present several load sharing alternatives. Our objective is to reduce the number of page faults caused by unbalanced memory allocations for jobs among distributed nodes, so that overall performance of a distributed system can be significantly improved. We have conducted trace-driven simulations to compare CPU-based load sharing policies with our policies. We show that our load sharing policies not only improve performance of memory bound jobs, but also maintain the same load sharing quality as the CPU-based policies for CPU-bound jobs. Regarding remote execution and preemptive migration strategies, our experiments indicate that a strategy selection in load sharing is dependent on the amount of memory demand of jobs, remote execution is more effective for memory-bound jobs, and preemptive migration is more effective for CPU-bound jobs. Our CPU-memory-based policy using either high performance or high throughput approach and using the remote execution strategy performs the best for both CPU-bound and memory-bound job in homogeneous networks of distributed environment.

Enterprise Reference Library

2011-01-01

Introduction: Johnson Space Center (JSC) offers two extensive libraries that contain journals, research literature and electronic resources. Searching capabilities are available to those individuals residing onsite or through a librarian s search. Many individuals have rich collections of references, but no mechanisms to share reference libraries across researchers, projects, or directorates exist. Likewise, information regarding which references are provided to which individuals is not available, resulting in duplicate requests, redundant labor costs and associated copying fees. In addition, this tends to limit collaboration between colleagues and promotes the establishment of individual, unshared silos of information The Integrated Medical Model (IMM) team has utilized a centralized reference management tool during the development, test, and operational phases of this project. The Enterprise Reference Library project expands the capabilities developed for IMM to address the above issues and enhance collaboration across JSC. Method: After significant market analysis for a multi-user reference management tool, no available commercial tool was found to meet this need, so a software program was built around a commercial tool, Reference Manager 12 by The Thomson Corporation. A use case approach guided the requirements development phase. The premise of the design is that individuals use their own reference management software and export to SharePoint when their library is incorporated into the Enterprise Reference Library. This results in a searchable user-specific library application. An accompanying share folder will warehouse the electronic full-text articles, which allows the global user community to access full -text articles. Discussion: An enterprise reference library solution can provide a multidisciplinary collection of full text articles. This approach improves efficiency in obtaining and storing reference material while greatly reducing labor, purchasing and

Legal Effects of Link Sharing in Social Networks

Eugenio Gil

2015-12-01

Full Text Available Knowledge sharing among individuals has changed deeply with the advent of social networks in the environment of Web 2.0. Every user has the possibility of publishing what he or she deems of interest for their audience, regardless of the origin or authorship of the piece of knowledge. It is generally accepted that as the user is sharing a link to a document or video, for example, without getting paid for it, there is no point in worrying about the rights of the original author. It seems that the concepts of authorship and originality is about to disappear as promised the structuralists fifty years ago. Nevertheless the legal system has not changed, nor have the economic interests concerned. This paper explores the last developments of the legal system concerning these issues.

Enabling Interoperable and Selective Data Sharing among Social Networking Sites

Science.gov (United States)

Shin, Dongwan; Lopes, Rodrigo

With the widespread use of social networking (SN) sites and even introduction of a social component in non-social oriented services, there is a growing concern over user privacy in general, how to handle and share user profiles across SN sites in particular. Although there have been several proprietary or open source-based approaches to unifying the creation of third party applications, the availability and retrieval of user profile information are still limited to the site where the third party application is run, mostly devoid of the support for data interoperability. In this paper we propose an approach to enabling interopearable and selective data sharing among SN sites. To support selective data sharing, we discuss an authenticated dictionary (ADT)-based credential which enables a user to share only a subset of her information certified by external SN sites with applications running on an SN site. For interoperable data sharing, we propose an extension to the OpenSocial API so that it can provide an open source-based framework for allowing the ADT-based credential to be used seamlessly among different SN sites.

Library management in the tight budget seventies. Problems, challenges, and opportunities.

White, H S

1977-01-01

This paper examines changes in the management of university, special, and medical libraries brought about by the budget curtailments that followed the more affluent funding period of the mid-1960s. Based on a study conducted for the National Science Foundation by the Indiana University Graduate Library School, this paper deals with misconceptions that have arisen in the relationship between publishers and librarians, and differentiates between the priority perceptions of academic and of special librarians in the allocation of progressively scarcer resources. It concludes that libraries must make strong efforts to reduce the growing erosion of materials acquisitions budgets because of growing labor costs as a percentage of all library expenditures; that they must make a working reality of the resource-sharing mechanisms established through consortia and networks; and that they must use advanced evaluative techniques in the determination of which services and programs to implement, expand, and retain, and which to curtail and abandon.

Virtual shelves in a digital library: a framework for access to networked information sources.

Patrick, T B; Springer, G K; Mitchell, J A; Sievert, M E

1995-01-01

Develop a framework for collections-based access to networked information sources that addresses the problem of location-dependent access to information sources. 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. 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. 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.

Case Library Construction Technology of Energy Loss in Distribution Networks Considering Regional Differentiation Theory

Directory of Open Access Journals (Sweden)

Ze Yuan

2017-11-01

Full Text Available The grid structures, load levels, and running states of distribution networks in different supply regions are known as the influencing factors of energy loss. In this paper, the case library of energy loss is constructed to differentiate the crucial factors of energy loss in the different supply regions. First of all, the characteristic state values are selected as the representation of the cases based on the analysis of energy loss under various voltage classes and in different types of regions. Then, the methods of Grey Relational Analysis and the K-Nearest Neighbor are utilized to implement the critical technologies of case library construction, including case representation, processing, analysis, and retrieval. Moreover, the analysis software of the case library is designed based on the case library construction technology. Some case studies show that there are many differences and similarities concerning the factors that influence the energy loss in different types of regions. In addition, the most relevant sample case can be retrieved from the case library. Compared with the traditional techniques, constructing a case library provides a new way to find out the characteristics of energy loss in different supply regions and constitutes differentiated loss-reducing programs.

Karlen, Walter; Dumont, Guy A; Scheffer, Cornie

2014-01-01

We propose a communication library, ShareVitalSigns, for the standardized exchange of vital sign information between health applications running on mobile platforms. The library allows an application to request one or multiple vital signs from independent measurement applications on the Android OS. Compatible measurement applications are automatically detected and can be launched from within the requesting application, simplifying the work flow for the user and reducing typing errors. Data is shared between applications using intents, a passive data structure available on Android OS. The library is accompanied by a test application which serves as a demonstrator. The secure exchange of vital sign information using a standardized library like ShareVitalSigns will facilitate the integration of measurement applications into diagnostic and other high level health monitoring applications and reduce errors due to manual entry of information.

NASA research programs are helping humanity understand the origin and evolution of galaxies, stars, and planets, how our Sun varies and impacts the heliosphere, and defining the conditions necessary to support life beyond Earth. As places that offer their services for free, public libraries have become the "public square" by providing a place where members of a community can gather for information, educational programming, and policy discussions. Libraries are also developing new ways to engage their patrons in STEM learning. The Space Science Institute's (SSI) National Center for Interactive Learning (NCIL) was funded by NASA`s Science Mission Directorate (SMD) to develop and implement a project called NASA@ My Library: A National Earth and Space Science Initiative That Connects NASA, Public Libraries and Their Communities. NCIL's STAR Library Network (STAR_Net) is providing important leverage to expand its community of practice that serves both librarians and STEM professionals. Seventy-five libraries were selected through a competitive application process to receive NASA STEM Facilitation Kits, NASA STEM Backpacks for circulation, financial resources, training, and partnership opportunities. Initial survey data from the 75 NASA@ My Library partners showed that, while they are actively providing programming, few STEM programs connected with NASA science and engineering. With the launch of the initiative - including training, resources, and STEM-related event opportunities - all 75 libraries are engaged in offering NASA-focused programs, including with NASA subject matter experts. This talk will highlight the impacts the initiative is having on both public library partners and many others across the country.

Full Text Available The utilization of the new information and communication technologies implies a series of changes concerning the libraries. Currently it is spoken more and more about a new type of service offered by them, Library 2.0, which brings in foreground the user who becomes a modeler of the library services and resources. The information structures customer is not satisfied anymore by the unidirectional access to the resources, he wanted to be involved in the evaluation of them, making comments and sharing his ideas with another user. In this sense the library managers are looking for more efficient means to deliver services so that to obtain a proper feedback which enable them to take the best measures to make profitable them. Library 2.0 can be a solution for all these problems.

The Semantic Document Library (SDL) was driven by use cases from the environmental observatory communities and is designed to provide conventional document repository features of uploading, downloading, editing and versioning of documents as well as value adding features of tagging, querying, sharing, annotating, ranking, provenance, social networking and geo-spatial mapping services. It allows users to organize a catalogue of watershed observation data, model output, workflows, as well publications and documents related to the same watershed study through the tagging capability. Users can tag all relevant materials using the same watershed name and find all of them easily later using this tag. The underpinning semantic content repository can store materials from other cyberenvironments such as workflow or simulation tools and SDL provides an effective interface to query and organize materials from various sources. Advanced features of the SDL allow users to visualize the provenance of the materials such as the source and how the output data is derived. Other novel features include visualizing all geo-referenced materials on a geospatial map. SDL as a component of a cyberenvironment portal (the NCSA Cybercollaboratory) has goal of efficient management of information and relationships between published artifacts (Validated models, vetted data, workflows, annotations, best practices, reviews and papers) produced from raw research artifacts (data, notes, plans etc.) through agents (people, sensors etc.). Tremendous scientific potential of artifacts is achieved through mechanisms of sharing, reuse and collaboration - empowering scientists to spread their knowledge and protocols and to benefit from the knowledge of others. SDL successfully implements web 2.0 technologies and design patterns along with semantic content management approach that enables use of multiple ontologies and dynamic evolution (e.g. folksonomies) of terminology.

Leskovec, Jure; Sosič, Rok

2016-10-01

Large networks are becoming a widely used abstraction for studying complex systems in a broad set of disciplines, ranging from social network analysis to molecular biology and neuroscience. Despite an increasing need to analyze and manipulate large networks, only a limited number of tools are available for this task. Here, we describe Stanford Network Analysis Platform (SNAP), a general-purpose, high-performance system that provides easy to use, high-level operations for analysis and manipulation of large networks. We present SNAP functionality, describe its implementational details, and give performance benchmarks. SNAP has been developed for single big-memory machines and it balances the trade-off between maximum performance, compact in-memory graph representation, and the ability to handle dynamic graphs where nodes and edges are being added or removed over time. SNAP can process massive networks with hundreds of millions of nodes and billions of edges. SNAP offers over 140 different graph algorithms that can efficiently manipulate large graphs, calculate structural properties, generate regular and random graphs, and handle attributes and meta-data on nodes and edges. Besides being able to handle large graphs, an additional strength of SNAP is that networks and their attributes are fully dynamic, they can be modified during the computation at low cost. SNAP is provided as an open source library in C++ as well as a module in Python. We also describe the Stanford Large Network Dataset, a set of social and information real-world networks and datasets, which we make publicly available. The collection is a complementary resource to our SNAP software and is widely used for development and benchmarking of graph analytics algorithms.

Information sharing and relationships on social networking sites.

Steijn, Wouter M P; Schouten, Alexander P

2013-08-01

This article investigates the relationship between sharing personal information and relationship development in the context of social networking sites (SNSs). Information disclosed on these sites could affect relationships in a different manner compared to more traditional interactions, such as instant messaging or face-to-face interaction. Respondents in the age range of 12 to 83 were surveyed about experiences of relationship development as a consequence of contact through Facebook or Hyves-the most popular Dutch SNSs. Results showed a primarily positive effect of information sharing on SNSs on our relationships. Furthermore, relationship development mainly occurs among acquaintances and friends, and public posts are most strongly related to relationship development. These findings suggest that SNSs might affect relationships in a distinct fashion as acquaintances and friends gain access to public self-disclosures that might normally only be reserved for close friends and family. Overall, this study provides an insight into some of the positive aspects of the public nature of SNSs in contrast with the general negative associations.

Full Text Available Facebook, MySpace, Flickr and YouTube are currently among the most frequently visited websites with Web 2.0 features. They are used not only for social networking and entertainment but also for access to information, for learning and for carrying out professional work. Social networks commonly have Web 2.0 features, offer personalized services and allow users to incorporate their own content easily and describe, organize and share it with others, thereby enriching users’ experience. Some users tend to “live” on those social networks and expect information providing organizations to offer similar services. They want libraries to be as accessible, flexible, open to collaboration and sharing as that of social networks and heighten the expectations from such institutions. The future of libraries is closely associated with how successfully they meet the demands of digital users. Otherwise, the “net generation” or the “digital natives” grown up with the Web, Google and Facebook would see libraries as outdated institutions and “take their business elsewhere” to satisfy their information needs. In this paper, the impact of the technological convergence on information providing organizations is reviewed and the challenges and opportunities facing libraries in the digital environment are discussed.

Modeling of frequency agile devices: development of PKI neuromodeling library based on hierarchical network structure

Science.gov (United States)

Sanchez, P.; Hinojosa, J.; Ruiz, R.

2005-06-01

Recently, neuromodeling methods of microwave devices have been developed. These methods are suitable for the model generation of novel devices. They allow fast and accurate simulations and optimizations. However, the development of libraries makes these methods to be a formidable task, since they require massive input-output data provided by an electromagnetic simulator or measurements and repeated artificial neural network (ANN) training. This paper presents a strategy reducing the cost of library development with the advantages of the neuromodeling methods: high accuracy, large range of geometrical and material parameters and reduced CPU time. The library models are developed from a set of base prior knowledge input (PKI) models, which take into account the characteristics common to all the models in the library, and high-level ANNs which give the library model outputs from base PKI models. This technique is illustrated for a microwave multiconductor tunable phase shifter using anisotropic substrates. Closed-form relationships have been developed and are presented in this paper. The results show good agreement with the expected ones.

In a hybrid (terrestrial + satellite) mobile personal communications networks environment, a large size satellite footprint (supercell) overlays on a large number of smaller size, contiguous terrestrial cells. We assume that the users have either a terrestrial only single mode terminal (SMT) or a terrestrial/satellite dual mode terminal (DMT) and the ratio of DMT to the total terminals is defined gamma. It is assumed that the call assignments to and handovers between terrestrial cells and satellite supercells take place in a dynamic fashion when necessary. The objectives of this paper are twofold, (1) to propose and define a class of traffic sharing algorithms to manage terrestrial and satellite network resources efficiently by handling call handovers dynamically, and (2) to analyze and evaluate the algorithms by maximizing the traffic load handling capability (defined in erl/cell) over a wide range of terminal ratios (gamma) given an acceptable range of blocking probabilities. Two of the algorithms (G & S) in the proposed class perform extremely well for a wide range of gamma.

Motte, Kristin; Caldwell, C Brooke; Lamson, Karen S; Ferimer, Suzanne; Nims, J Chris

2014-10-01

This Association of Vision Science Librarians revision of the "Standards for Vision Science Libraries" aspires to provide benchmarks to address the needs for the services and resources of modern vision science libraries (academic, medical or hospital, pharmaceutical, and so on), which share a core mission, are varied by type, and are located throughout the world. Through multiple meeting discussions, member surveys, and a collaborative revision process, the standards have been updated for the first time in over a decade. While the range of types of libraries supporting vision science services, education, and research is wide, all libraries, regardless of type, share core attributes, which the standards address. The current standards can and should be used to help develop new vision science libraries or to expand the growth of existing libraries, as well as to support vision science librarians in their work to better provide services and resources to their respective users.

Interference-Aware Spectrum Sharing Techniques for Next Generation Wireless Networks

KAUST Repository

Qaraqe, Marwa Khalid

2011-11-20

Background: Reliable high-speed data communication that supports multimedia application for both indoor and outdoor mobile users is a fundamental requirement for next generation wireless networks and requires a dense deployment of physically coexisting network architectures. Due to the limited spectrum availability, a novel interference-aware spectrum-sharing concept is introduced where networks that suffer from congested spectrums (secondary-networks) are allowed to share the spectrum with other networks with available spectrum (primary-networks) under the condition that limited interference occurs to primary networks. Objective: Multiple-antenna and adaptive rate can be utilized as a power-efficient technique for improving the data rate of the secondary link while satisfying the interference constraint of the primary link by allowing the secondary user to adapt its transmitting antenna, power, and rate according to the channel state information. Methods: Two adaptive schemes are proposed using multiple-antenna transmit diversity and adaptive modulation in order to increase the spectral-efficiency of the secondary link while maintaining minimum interference with the primary. Both the switching efficient scheme (SES) and bandwidth efficient scheme (BES) use the scan-and-wait combining antenna technique (SWC) where there is a secondary transmission only when a branch with an acceptable performance is found; else the data is buffered. Results: In both these schemes the constellation size and selected transmit branch are determined to minimized the average number of switches and achieve the highest spectral efficiency given a minimum bit-error-rate (BER), fading conditions, and peak interference constraint. For delayed sensitive applications, two schemes using power control are used: SES-PC and BES-PC. In these schemes the secondary transmitter sends data using a nominal power level, which is optimized to minimize the average delay. Several numerical examples show

Growing the Data Refuge Project into a Local Libraries+ Network Node

Janz, M.

2017-12-01

The Data Refuge project began as concerns were raised about the vulnerability of federal climate and environmental data. The concern stemmed from the idea that if the federal agency that curates the data lost funding, and with it staff and infrastructure, that the data could be lost. The team worked to determine what factors contributed to the vulnerability of these data and how we might mitigate their risks. After speaking with many partners and collaborators around the country who all had different roles and perspectives working with these data, we saw the landscape of government data in new ways. We began seeing potential in various initiatives to ensure continued access to these data regardless of political, technological, or other risks. One recurring theme in our assessment was that libraries would be natural backup stewards for federal data.From and with our partners, we learned just how complicated the problem of creating networks of backup stewards for government data would be, but also how important it is to make the effort. As Data Refuge moves into its next stages into the Libraries+ Network, we're making plans to work with our partners on federal, state, and local projects that address different aspects of the problem space. These projects are examples of ways to approach this problem in concert with a variety of stakeholders.

Blockchain-Empowered Fair Computational Resource Sharing System in the D2D Network

Directory of Open Access Journals (Sweden)

Zhen Hong

2017-11-01

Full Text Available Device-to-device (D2D communication is becoming an increasingly important technology in future networks with the climbing demand for local services. For instance, resource sharing in the D2D network features ubiquitous availability, flexibility, low latency and low cost. However, these features also bring along challenges when building a satisfactory resource sharing system in the D2D network. Specifically, user mobility is one of the top concerns for designing a cooperative D2D computational resource sharing system since mutual communication may not be stably available due to user mobility. A previous endeavour has demonstrated and proven how connectivity can be incorporated into cooperative task scheduling among users in the D2D network to effectively lower average task execution time. There are doubts about whether this type of task scheduling scheme, though effective, presents fairness among users. In other words, it can be unfair for users who contribute many computational resources while receiving little when in need. In this paper, we propose a novel blockchain-based credit system that can be incorporated into the connectivity-aware task scheduling scheme to enforce fairness among users in the D2D network. Users’ computational task cooperation will be recorded on the public blockchain ledger in the system as transactions, and each user’s credit balance can be easily accessible from the ledger. A supernode at the base station is responsible for scheduling cooperative computational tasks based on user mobility and user credit balance. We investigated the performance of the credit system, and simulation results showed that with a minor sacrifice of average task execution time, the level of fairness can obtain a major enhancement.

The Library of Integrated Network-Based Cellular Signatures (LINCS) is an NIH Common Fund program that catalogs how human cells globally respond to chemical, genetic, and disease perturbations. Resources generated by LINCS include experimental and computational methods, visualization tools, molecular and imaging data, and signatures. By assembling an integrated picture of the range of responses of human cells exposed to many perturbations, the LINCS program aims to better understand human disease and to advance the development of new therapies. Perturbations under study include drugs, genetic perturbations, tissue micro-environments, antibodies, and disease-causing mutations. Responses to perturbations are measured by transcript profiling, mass spectrometry, cell imaging, and biochemical methods, among other assays. The LINCS program focuses on cellular physiology shared among tissues and cell types relevant to an array of diseases, including cancer, heart disease, and neurodegenerative disorders. This Perspective describes LINCS technologies, datasets, tools, and approaches to data accessibility and reusability. Copyright © 2017 Elsevier Inc. All rights reserved.

A distributed authentication and authorization scheme for in-network big data sharing

Directory of Open Access Journals (Sweden)

Ruidong Li

2017-11-01

Full Text Available Big data has a strong demand for a network infrastructure with the capability to support data sharing and retrieval efficiently. Information-centric networking (ICN is an emerging approach to satisfy this demand, where big data is cached ubiquitously in the network and retrieved using data names. However, existing authentication and authorization schemes rely mostly on centralized servers to provide certification and mediation services for data retrieval. This causes considerable traffic overhead for the secure distributed sharing of data. To solve this problem, we employ identity-based cryptography (IBC to propose a Distributed Authentication and Authorization Scheme (DAAS, where an identity-based signature (IBS is used to achieve distributed verifications of the identities of publishers and users. Moreover, Ciphertext-Policy Attribute-based encryption (CP-ABE is used to enable the distributed and fine-grained authorization. DAAS consists of three phases: initialization, secure data publication, and secure data retrieval, which seamlessly integrate authentication and authorization with the interest/data communication paradigm in ICN. In particular, we propose trustworthy registration and Network Operator and Authority Manifest (NOAM dissemination to provide initial secure registration and enable efficient authentication for global data retrieval. Meanwhile, Attribute Manifest (AM distribution coupled with automatic attribute update is proposed to reduce the cost of attribute retrieval. We examine the performance of the proposed DAAS, which shows that it can achieve a lower bandwidth cost than existing schemes.

Information Sharing Mechanism among Mobile Agents In Ad-hoc Network Environment and Its Applications

Directory of Open Access Journals (Sweden)

Kunio Umetsuji

2004-12-01

Full Text Available Mobile agents are programs that can move from one site to another in a network with their data and states. Mobile agents are expected to be an essential tool in pervasive computing. In multi platform environment, it is important to communicate with mobile agents only using their universal or logical name not using their physical locations. More, in an ad-hoc network environment, an agent can migrate autonomously and communicate with other agents on demand. It is difficult that mobile agent grasps the position information on other agents correctly each other, because mobile agent processes a task while moving a network successively. In order to realize on-demand mutual communication among mobile agents without any centralized servers, we propose a new information sharing mechanism within mobile agents. In this paper, we present a new information sharing mechanism within mobile agents. The method is a complete peer based and requires no agent servers to manage mobile agent locations. Therefore, a mobile agent can get another mobile agent, communicate with it and shares information stored in the agent without any knowledge of the location of the target mobile agent. The basic idea of the mechanism is an introduction of Agent Ring, Agent Chain and Shadow Agent. With this mechanism, each agent can communicate with other agents in a server-less environment, which is suitable for ad-hoc agent network and an agent system can manage agents search and communications efficiently.

A Measurement Study of the Structured Overlay Network in P2P File-Sharing Systems

Directory of Open Access Journals (Sweden)

Mo Zhou

2007-01-01

Full Text Available The architecture of P2P file-sharing applications has been developing to meet the needs of large scale demands. The structured overlay network, also known as DHT, has been used in these applications to improve the scalability, and robustness of the system, and to make it free from single-point failure. We believe that the measurement study of the overlay network used in the real file-sharing P2P systems can provide guidance for the designing of such systems, and improve the performance of the system. In this paper, we perform the measurement in two different aspects. First, a modified client is designed to provide view to the overlay network from a single-user vision. Second, the instances of crawler programs deployed in many nodes managed to crawl the user information of the overlay network as much as possible. We also find a vulnerability in the overlay network, combined with the character of the DNS service, a more serious DDoS attack can be launched.

Groen, Derek; Rieder, Steven; Zwart, Simon Portegies; Grosso, Paola; Laat, Cees de

2010-01-01

We present MPWide, a platform-independent communication library for performing message passing between computers. Our library allows coupling of several local message passing interface (MPI) applications through a long-distance network and is specifically optimized for such communications. The implementation is deliberately kept lightweight and platform independent, and the library can be installed and used without administrative privileges. The only requirements are a C++ compiler and at least one open port to a wide-area network on each site. In this paper we present the library, describe the user interface, present performance tests and apply MPWide in a large-scale cosmological N-body simulation on a network of two computers, one in Amsterdam and the other in Tokyo.

Critical Factors to Achieve Dockless Bike-Sharing Sustainability in China: A Stakeholder-Oriented Network Perspective

Directory of Open Access Journals (Sweden)

Jian-gang Shi

2018-06-01

Full Text Available In China, dockless bike-sharing programs (DBSPs play a significant role in promoting the goals of sustainable urban travel and carbon emissions reduction. However, the sustainability of DBSPs is increasingly being challenged as various issues associated with different stakeholders emerge. While numerous studies have focused on the barriers to traditional bike-sharing programs, the sustainability performance of new-generation DBSPs is largely overlooked. It is accordingly imperative to understand the primary challenges that impede the sustainability of DBSPs and to consider what stimulative measures can be taken. In this study, we investigate the factors that are critical to DBSPs’ sustainability from a network perspective. Stakeholder-associated factors and their interrelations were identified via literature analysis and interviews, and the social network analysis (SNA method was employed to recognize the critical factors and links in DBSPs. As a result, 10 critical factors and 10 major interactions were identified and further classified into six challenges. Sharing transport schemes, legislative perfection, public private partnership (PPP, and product lifecycle management (PLM were proposed to govern these challenges. This paper contributes to the existing body of knowledge of bike-sharing programs via a network approach that integrates the key influencing factors with those factors’ associated stakeholders. Furthermore, these findings provide the government and operators with implications for mitigating the tough challenges and facilitating the sustainability of DBSPs.

The virtual library: Coming of age

Science.gov (United States)

Hunter, Judy F.; Cotter, Gladys A.

1994-01-01

With the high speed networking capabilities, multiple media options, and massive amounts of information that exist in electronic format today, the concept of a 'virtual' library or 'library without walls' is becoming viable. In virtual library environment, the information processed goes beyond the traditional definition of documents to include the results of scientific and technical research and development (reports, software, data) recorded in any format or media: electronic, audio, video, or scanned images. Network access to information must include tools to help locate information sources and navigate the networks to connect to the sources, as well as methods to extract the relevant information. Graphical User Interfaces (GUI's) that are intuitive and navigational tools such as Intelligent Gateway Processors (IGP) will provide users with seamless and transparent use of high speed networks to access, organize, and manage information. Traditional libraries will become points of electronic access to information on multiple medias. The emphasis will be towards unique collections of information at each library rather than entire collections at every library. It is no longer a question of whether there is enough information available; it is more a question of how to manage the vast volumes of information. The future equation will involve being able to organize knowledge, manage information, and provide access at the point of origin.

The information society, especially library users, expects an easier and faster way to get information and share knowledge. The library also implements the best way to provide the best service and the easiest way to disseminate and share information with its users. One technology that allows libraries more closely with their users is mobile technology. This paper aims to determine the basic conditions of mobile technology services and mobile services most needed library users, as well as constraints faced by libraries and users in the application of mobile technology. This paper will help libraries to develop better M-Library services in expanding the reach of library services. Methods of data collection were conducted through surveys through questionnaires, interviews, and direct observation. The results of the use of mobile technology applications in libraries bring great advantages to provide better library services and to improve accessibility of library resources in the easiest way, but due to lack of funds, lack of skills and lack of staff, many libraries are unable to provide this service with very successful.

Full Text Available Social networks have rapidly won their place in our life and in the activity of many private and public organizations and institutions. At library level, social networks have demonstrated their role as good marketing tools and their utility for a better communication with users. Public libraries in Romania have lately experienced great transformations in terms of the approach of their relationship with the users and the improvement of their activity. They have also launched a series of new services in order to meet the needs of the community they serve and to attract new users. Implementing and using new applications such as online social networks, more exactly Facebook was one of these recent developments. This paper analyzes the way in which social networks are used at the level of public libraries in Romania by the example of three large public libraries and the way in which these libraries advertise their services through Facebook.

2013-04-01

The “Astro4Girls and Their Families” pilot program offered a variety of informal science events at nine public libraries nationwide in conjunction with Women's History Month (March) 2012. The goals were to engage girls and their families in science, by helping them discover the Universe for themselves and celebrating the contribution of women to astronomy and science. We offered a wide range of activities, from using robotic telescopes for “Do-It-Yourself (DIY) astrophotography” to making edible black holes, to exploring the infrared Universe. Our main target audience was middle-school aged girls, but students of all ages, their families and the public were welcome to participate in many of the activities. Five NASA Science Mission Directorate-funded Astrophysics Education and Public Outreach teams partnered with public libraries in this pilot program; each worked with 1 or 2 libraries to offer a total of about 15 events reaching over 300 people in both urban and rural areas. The American Library Association Public Programs Office identified participating libraries and facilitated their participation through its role in the SMD-funded “Visions of the Universe: Four Centuries of Discovery” traveling exhibit. The NASA Astrophysics Science Education and Public Outreach Forum coordinated the collaboration. The website is: http://www.ala.org/programming/astro4girls. This poster outlines the details of planning and implementing the 2012 pilot program, its successes, and lessons learned. The collaborators would like to engage the EPO community in a discussion of how to sustain Astro4Girls and engage additional public libraries nationwide during future Women's History Months.

Stories of Informal Mentorship: Recognizing the Voices of Mentees in Academic Libraries

Directory of Open Access Journals (Sweden)

Colleen MacKinnon

2014-04-01

Full Text Available Based on the 2014 OLA Super Conference session “Mentorship in Academic Libraries: A Universe of Possibilities,” this article explores the benefits of informal mentorship in its various forms and how librarians are embracing a new way of thinking about mentorship both individually and organizationally. The lived experiences of two professional academic librarians are shared as they argue that informal mentorship offers the opportunity to co-create a meaningful mentorship experience by recognizing the importance of the mentee’s voice. This paper will discuss the value of informal mentorship and how, when certain elements are present within it, this model can allow us to reimagine mentorship in academic libraries. Concepts such as “accidental” mentorship, “purposeful” mentorship, mentorship “network,” and “peer” mentorship are discussed.

Science.gov (United States)

Garcia-Milian, Rolando; Norton, Hannah F; Tennant, Michele R

2012-01-01

Social networks such as Facebook allow libraries to be proactive in reaching their users. While some libraries have popular Facebook pages, it remains unclear what attracts users to these pages. This study evaluates relationships between libraries' Facebook page content and popularity. An analysis of 72 academic health sciences libraries' Facebook pages showed positive correlations between number of library fans and number of tabs, photos, events, and wall posts on Facebook. Libraries posting videos had significantly more fans than libraries without them. This study contributes to an understanding of correlations between content and popularity on Facebook, with implications for library outreach.

My Own Private Public Library

Julia Rone

2014-11-01

Full Text Available The present paper analyzes the emergence of Bulgarian digital libraries with pirated literature as a form of compensation for the failure of both the state and the market to provide easy access to electronic books in Bulgarian. These grass-roots digital libraries can be understood best through an analysis of the dichotomies between formal and informal economy, law and ethics, commercial and non-commercial interest, bricolage and engineering. Sharing of books online in Bulgaria has its historical precedent in the sharing of cultural objects during socialism and is part of the larger logic of informal economy as a form of independence from/resistance to the state. While many of the books in these electronic libraries are uploaded in infringement of copyright, the creators and users of the sites defend them on the basis of what is ethically right and claim that they contribute to the spread of knowledge. The paper emphasizes the rhetorical force of the word ‘library’ which is being appropriated by both commercial and non-commercial actors. Without underestimating the value provided by many of the grass-roots digital libraries discussed, the analysis leads to the question whether the bottom-up collaborative strategy for digitizing books is the optimal one in terms of the variety of titles offered and the overall coherence of digital archives. In short, should sharing replace more traditional state policies in the field of culture?

The Share of Preservation Issues when Planning a Library Building

Directory of Open Access Journals (Sweden)

Marie-Thérèse Varlamoff

2002-07-01

Full Text Available Primarily and historically a library was a place where books or manuscripts were kept. „ Thékos” means warehouse or storage area in Greek. But nowadays a library is more than a depository. It is also a place where you can read books and access the information they contain. In the case of a new building or of the rehabilitation of an old building it might also serve as a showcase for politicians or decision makers. Hence the necessity to combine preservation issues, accessibility and architecture.

Stewart, Samuel Alan; Abidi, Syed Sibte Raza

2012-12-04

Knowledge Translation (KT) plays a vital role in the modern health care community, facilitating the incorporation of new evidence into practice. Web 2.0 tools provide a useful mechanism for establishing an online KT environment in which health practitioners share their practice-related knowledge and experiences with an online community of practice. We have implemented a Web 2.0 based KT environment--an online discussion forum--for pediatric pain practitioners across seven different hospitals in Thailand. The online discussion forum enabled the pediatric pain practitioners to share and translate their experiential knowledge to help improve the management of pediatric pain in hospitals. The goal of this research is to investigate the knowledge sharing dynamics of a community of practice through an online discussion forum. We evaluated the communication patterns of the community members using statistical and social network analysis methods in order to better understand how the online community engages to share experiential knowledge. Statistical analyses and visualizations provide a broad overview of the communication patterns within the discussion forum. Social network analysis provides the tools to delve deeper into the social network, identifying the most active members of the community, reporting the overall health of the social network, isolating the potential core members of the social network, and exploring the inter-group relationships that exist across institutions and professions. The statistical analyses revealed a network dominated by a single institution and a single profession, and found a varied relationship between reading and posting content to the discussion forum. The social network analysis discovered a healthy network with strong communication patterns, while identifying which users are at the center of the community in terms of facilitating communication. The group-level analysis suggests that there is strong interprofessional and interregional

Schizophrenia and autism spectrum disorder (ASD) are two prevalent neurodevelopmental disorders sharing some similar genetic basis and clinical features. The extent to which they share common neural substrates remains unclear. Resting-state fMRI data were collected from 35 drug-naïve adolescent participants with first-episode schizophrenia (15.6 ± 1.8 years old) and 31 healthy controls (15.4 ± 1.6 years old). Data from 22 participants with ASD (13.1 ± 3.1 years old) and 21 healthy controls (12.9 ± 2.9 years old) were downloaded from the Autism Brain Imaging Data Exchange. Resting-state functional networks were constructed using predefined regions of interest. Multivariate pattern analysis combined with multi-task regression feature selection methods were conducted in two datasets separately. Classification between individuals with disorders and controls was achieved with high accuracy (schizophrenia dataset: accuracy = 83%; ASD dataset: accuracy = 80%). Shared atypical brain connections contributing to classification were mostly present in the default mode network (DMN) and salience network (SN). These functional connections were further related to severity of social deficits in ASD (p = 0.002). Distinct atypical connections were also more related to the DMN and SN, but showed different atypical connectivity patterns between the two disorders. These results suggest some common neural mechanisms contributing to schizophrenia and ASD, and may aid in understanding the pathology of these two neurodevelopmental disorders. Autism Res 2017, 10: 1776-1786. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Autism spectrum disorder (ASD) and schizophrenia are two common neurodevelopmental disorders which share several genetic and behavioral features. The present study identified common neural mechanisms contributing to ASD and schizophrenia using resting-state functional MRI data. The results may help to understand

A Group Based Key Sharing and Management Algorithm for Vehicular Ad Hoc Networks

Directory of Open Access Journals (Sweden)

Zeeshan Shafi Khan

2014-01-01

Full Text Available Vehicular ad hoc networks (VANETs are one special type of ad hoc networks that involves vehicles on roads. Typically like ad hoc networks, broadcast approach is used for data dissemination. Blind broadcast to each and every node results in exchange of useless and irrelevant messages and hence creates an overhead. Unicasting is not preferred in ad-hoc networks due to the dynamic topology and the resource requirements as compared to broadcasting. Simple broadcasting techniques create several problems on privacy, disturbance, and resource utilization. In this paper, we propose media mixing algorithm to decide what information should be provided to each user and how to provide such information. Results obtained through simulation show that fewer number of keys are needed to share compared to simple broadcasting. Privacy is also enhanced through this approach.

Uncovering collective listening habits and music genres in bipartite networks

Science.gov (United States)

Lambiotte, R.; Ausloos, M.

2005-12-01

In this paper, we analyze web-downloaded data on people sharing their music library, that we use as their individual musical signatures. The system is represented by a bipartite network, nodes being the music groups and the listeners. Music groups’ audience size behaves like a power law, but the individual music library size is an exponential with deviations at small values. In order to extract structures from the network, we focus on correlation matrices, that we filter by removing the least correlated links. This percolation idea-based method reveals the emergence of social communities and music genres, that are visualized by a branching representation. Evidence of collective listening habits that do not fit the neat usual genres defined by the music industry indicates an alternative way of classifying listeners and music groups. The structure of the network is also studied by a more refined method, based upon a random walk exploration of its properties. Finally, a personal identification-community imitation model for growing bipartite networks is outlined, following Potts ingredients. Simulation results do reproduce quite well the empirical data.

The local library across the digital and physical city: Opportunities for economic development

Kirralie Houghton

2014-07-01

Full Text Available This paper considers the role of the public library as a community hub, engagement space, and entrepreneurial incubator in the context of the city, city governance, and local government planning. It considers this role from the perspective of library experts and their future visions for libraries in a networked knowledge economy. Public libraries (often operated by or on behalf of local governments potentially play a pivotal role for local governments in positioning communities within the global digital network. Fourteen qualitative interviews with library experts informed the study which investigates how the relationship between digital technology and the physical library space can potentially support the community to develop innovative, collaborative environments for transitioning to a digital future. The study found that libraries can capitalise on their position as community hubs for two purposes: first, to build vibrant community networks and forge economic links across urban localities; and second, to cross the digital divide and act as places of innovation and lifelong learning. Libraries provide a specific combination of community and technology spaces and have significant tangible connection points in the digital age. The paper further discusses the potential benefits for libraries in using ICT networks and infrastructure, such as the National Broadband Network in Australia. These networks could facilitate greater use of library assets and community knowledge, which, in turn, could assist knowledge economies and regional prosperity.

Network Based Educational Environment How Libraries and Librarians Become Organizers of Knowledge Access and Resources

2000-01-01

In this paper we will highlight some important issues which will influence the redefinition of roles and duties of libraries and librarians in a networked based educational environment. Although librarians will also keep their traditional roles of faculty support services as well as reference service and research assistance, we identify the participation in the instructional design process, the support in the evaluation, development and use of a proper authoring system and the customization of information access, as being the domains where libraries and librarians should mainly involve themselves in the next future and make profit of their expertise in information and knowledge organization in order to properly and effectively support the institutions in the use of Information Technology in education.

Data at Risk and Research Libraries

Choudhury, S.

2017-12-01

Research libraries have recently engaged in data rescue events amidst growing concerns about access to federal data sets. While these efforts are well intentioned, libraries run the risk of ignoring a long established history of activities and accomplishments by other communities focused on data at risk, many of which are represented at forums such as AGU. Under the auspices of the Data Conservancy, the Sheridan Libraries at Johns Hopkins University hosted an event in July 2017 that convened members of various communities including ESIP, RDA, Data Rescue Boulder, Association of Research Libraries, the Fedora repository platform, the Open Science Framework and the Interplanetary File System or IPFS (via the Data Together Network). This group identified a potential role for research libraries to partner with existing players in the data at risk community by focusing on a distributed preservation network as part of a coordinated collection development program. This session will offer an opportunity to hear about this potential role for research libraries and to provide feedback about its viability and utility.

Benefit of adaptive FEC in shared backup path protected elastic optical network.

Science.gov (United States)

Guo, Hong; Dai, Hua; Wang, Chao; Li, Yongcheng; Bose, Sanjay K; Shen, Gangxiang

2015-07-27

We apply an adaptive forward error correction (FEC) allocation strategy to an Elastic Optical Network (EON) operated with shared backup path protection (SBPP). To maximize the protected network capacity that can be carried, an Integer Linear Programing (ILP) model and a spectrum window plane (SWP)-based heuristic algorithm are developed. Simulation results show that the FEC coding overhead required by the adaptive FEC scheme is significantly lower than that needed by a fixed FEC allocation strategy resulting in higher network capacity for the adaptive strategy. The adaptive FEC allocation strategy can also significantly outperform the fixed FEC allocation strategy both in terms of the spare capacity redundancy and the average FEC coding overhead needed per optical channel. The proposed heuristic algorithm is efficient and not only performs closer to the ILP model but also does much better than the shortest-path algorithm.

Although cardiovascular disease (CVD) and type 2 diabetes mellitus (T2D) share many common risk factors, potential molecular mechanisms that may also be shared for these 2 disorders remain unknown. Using an integrative pathway and network analysis, we performed genome-wide association studies in 8155 blacks, 3494 Hispanic American, and 3697 Caucasian American women who participated in the national Women's Health Initiative single-nucleotide polymorphism (SNP) Health Association Resource and the Genomics and Randomized Trials Network. Eight top pathways and gene networks related to cardiomyopathy, calcium signaling, axon guidance, cell adhesion, and extracellular matrix seemed to be commonly shared between CVD and T2D across all 3 ethnic groups. We also identified ethnicity-specific pathways, such as cell cycle (specific for Hispanic American and Caucasian American) and tight junction (CVD and combined CVD and T2D in Hispanic American). In network analysis of gene-gene or protein-protein interactions, we identified key drivers that included COL1A1, COL3A1, and ELN in the shared pathways for both CVD and T2D. These key driver genes were cross-validated in multiple mouse models of diabetes mellitus and atherosclerosis. Our integrative analysis of American women of 3 ethnicities identified multiple shared biological pathways and key regulatory genes for the development of CVD and T2D. These prospective findings also support the notion that ethnicity-specific susceptibility genes and process are involved in the pathogenesis of CVD and T2D. © 2014 American Heart Association, Inc.

Modelling of P2P-Based Video Sharing Performance for Content-Oriented Community-Based VoD Systems in Wireless Mobile Networks

Directory of Open Access Journals (Sweden)

Shijie Jia

2016-01-01

Full Text Available The video sharing performance is a key factor for scalability and quality of service of P2P VoD systems in wireless mobile networks. There are some impact factors for the video sharing performance, such as available upload bandwidth, resource distribution in overlay networks, and mobility of mobile nodes. In this paper, we firstly model user behaviors: joining, playback, and departure for the content-oriented community-based VoD systems in wireless mobile networks and construct a resource assignment model by the analysis of transition of node state: suspend, wait, and playback. We analyze the influence of the above three factors: upload bandwidth, startup delay, and resource distribution for the sharing performance and QoS of systems. We further propose the improved resource sharing strategies from the perspectives of community architecture, resource distribution, and data transmission for the systems. Extensive tests show how the improved strategies achieve much better performance results in comparison with original strategies.

Paul Ayris

2012-01-01

Full Text Available The purpose of this article is to explain what academic and national libraries can do to continue to offer services and facilities at a time of economic difficulties. It identifies a number of methodologies and opportunities that are open to libraries and takes the view that it is never wise to waste a good crisis, because all threats are really opportunities in disguise. The article looks at the initial economic context for European research libraries and then examines ways in which libraries can tackle the threats which the current financial crisis poses. Joint procurement is one way in which libraries can achieve value for money, and the paper examines the role of JIS C Collections in the UK. Innovation through collaboration and shared services are also ways in which libraries can innovate/make savings in a cost-effective way by sharing the burden of costs around the partnership. The paper gives two examples: one which is now well established, the DART-Europe portal for Open Access e-theses; and one which is in the early stages of being discussed — a cloud-based solution for true collaborative cataloguing amongst the UK’s research and national libraries. The European Research Area (ERA and the contributions that libraries can make to this infrastructure through innovative EU project funding are analysed in some detail by looking at LI BER’s EU project portfolio. Finally, change and growth can come through changes to legal frameworks, and the paper looks at the Hargreaves review of copyright frameworks in the UK and the launch of the new library-based EU lobbying group for copyright reform, Information Sans Frontières (IS F.

Full-Duplex opportunistic relay selection in future spectrum-sharing networks

KAUST Repository

Khafagy, Mohammad Galal; Alouini, Mohamed-Slim; Aï ssa, Sonia

2015-01-01

We propose and analyze the performance of full-duplex relay selection in primary/secondary spectrum-sharing networks. Contrary to half-duplex relaying, full-duplex relaying (FDR) enables simultaneous listening/forwarding at the secondary relay, thereby allowing for a higher spectral efficiency. However, since the source and relay simultaneously transmit in FDR, their superimposed signal at the primary receiver should now satisfy the existing interference constraint which can considerably limit the secondary network throughput. In this regard, relay selection can offer an adequate solution to boost the secondary throughput while satisfying the imposed interference limit. We first analyze the performance of opportunistic relay selection among a cluster of full-duplex decode-and-forward relays with self-interference by deriving the exact cumulative distribution function of its end-to-end signal-to-noise ratio. Second, we evaluate the end-to-end performance of relay selection with interference constraints due to the presence of a primary receiver. Finally, the presented exact theoretical findings are verified by numerical simulations.

We tested the willingness of an online diabetes community to share data for public health research by providing members with a privacy-preserving social networking software application for rapid temporal-geographic surveillance of glycemic control.SN-mediated collection of cross-sectional, member-reported data from an international online diabetes SN entered into a software application we made available in a "Facebook-like" environment to enable reporting, charting and optional sharing of recent hemoglobin A1c values through a geographic display. Self-enrollment by 17% (n = 1,136 of n = 6,500 active members representing 32 countries and 50 US states. Data were current with 83.1% of most recent A1c values reported obtained within the past 90 days. Sharing was high with 81.4% of users permitting data donation to the community display. 34.1% of users also displayed their A1cs on their SN profile page. Users selecting the most permissive sharing options had a lower average A1c (6.8% than users not sharing with the community (7.1%, p = .038. 95% of users permitted re-contact. Unadjusted aggregate A1c reported by US users closely resembled aggregate 2007-2008 NHANES estimates (respectively, 6.9% and 6.9%, p = 0.85.Success within an early adopter community demonstrates that online SNs may comprise efficient platforms for bidirectional communication with and data acquisition from disease populations. Advancing this model for cohort and translational science and for use as a complementary surveillance approach will require understanding of inherent selection and publication (sharing biases in the data and a technology model that supports autonomy, anonymity and privacy.

SN-mediated collection of cross-sectional, member-reported data from an international online diabetes SN entered into a software application we made available in a "Facebook-like" environment to enable reporting, charting and optional sharing of recent hemoglobin A1c values through a geographic display. Self-enrollment by 17% (n = 1,136) of n = 6,500 active members representing 32 countries and 50 US states. Data were current with 83.1% of most recent A1c values reported obtained within the past 90 days. Sharing was high with 81.4% of users permitting data donation to the community display. 34.1% of users also displayed their A1cs on their SN profile page. Users selecting the most permissive sharing options had a lower average A1c (6.8%) than users not sharing with the community (7.1%, p = .038). 95% of users permitted re-contact. Unadjusted aggregate A1c reported by US users closely resembled aggregate 2007-2008 NHANES estimates (respectively, 6.9% and 6.9%, p = 0.85). Success within an early adopter community demonstrates that online SNs may comprise efficient platforms for bidirectional communication with and data acquisition from disease populations. Advancing this model for cohort and translational science and for use as a complementary surveillance approach will require understanding of inherent selection and publication (sharing) biases in the data and a technology model that supports autonomy, anonymity and privacy.

Full Text Available The aim of this inquiry is to investigate the relationships among the antecedents of knowledge sharing effectiveness under the position of non-academic staff of higher learning institutions through an empirical test of a conceptual model consisting of trust, extrinsic and intrinsic motivation, leadership style, workplace spirituality and online social network. This study used the respondents from the non-academic staff of higher learning institutions in Malaysia (n = 200, utilizing a self-administered survey questionnaire. The structural equation modeling approach was used to test the proposed hypotheses. The outcomes indicate that all the antecedents play a substantial function in knowledge sharing effectiveness. In addition, perceived risk plays a mediating role between trust and knowledge sharing effectiveness. On the other hand, this research also proved the communication skill also plays a mediating role between leadership style and knowledge sharing effectiveness. This study contributes to pioneering empirical findings on knowledge sharing literature under the scope of the non-academic staff perspective.

2011-12-01

A picture is worth a thousand of words, and every day hundreds of scientists, students, and environmentally aware citizens are taking field photos to document their observations of rocks, glaciers, soils, forests, wetlands, croplands, rangelands, livestock, and birds and mammals, as well as important events such as droughts, floods, wildfires, insect emergences, and infectious disease outbreaks. Where are those field photos stored? Can they be shared in a timely fashion to support education, research, and the leisure activities of citizens across the world? What are the financial and intellectual costs if those field photos are lost or not shared? Recently, researchers at the University of Oklahoma developed and released the Global Geo-Referenced Field Photo Library (hereinafter referred to as the Field Photo Library; http://www.eomf.ou.edu/photos/), a Web-based data portal designed for researchers and educators who wish to archive and share field photos from across the world, each tagged with exact positioning data (Figure 1). The data portal has a simple user interface that allows people to upload, query, and download georeferenced field photos in the library.

This paper aims to explore and study the current usage trends of Web2.0 namely Facebook, RSS, Blogs and Twitter among selected higher education institutions’ libraries in 6 gulf countries namely: Kingdom of Saudi Arabia, United Arab Emirates, Qatar, Bahrain, Oman and Kuwait. Websites of the selected libraries would be compared on the extent of the usage of these tools, the participation level and their purpose. The author would also share his opinion and suggestions on improving the current trends pertaining to the area of Web2.0 and libraries. The impact and importance of Web2.0 on libraries cannot be disputed. Since gaining popularity in mid-2000, libraries around the globe have jumped onto the Web2.0 bandwagon. Among the common examples of Web2.0 used by libraries today are namely: social networking sites, blogs, wikis, folksonomies and video sharing sites. Libraries are using Web2.0 to (among others): • market their services / resources to their community, • announce latest library news, • provide their online guides / notes for their resources among others. Though such tools have been implemented by most libraries around the world, some of the challenges faced by libraries are: •participation level – casting the net to a wider audience •selection of web2.0 tools •effectiveness of present web2.0 tools used by the libraries

The Use of Personal Value Estimations to Select Images for Preservation in Public Library Digital Community Collections

Directory of Open Access Journals (Sweden)

Andrea Copeland

2014-05-01

Full Text Available A considerable amount of information, particularly in image form, is shared on the web through social networking sites. If any of this content is worthy of preservation, who decides what is to be preserved and based on what criteria. This paper explores the potential for public libraries to assume this role of community digital repositories through the creation of digital collections. Thirty public library users and thirty librarians were solicited from the Indianapolis metropolitan area to evaluate five images selected from Flickr in terms of their value to public library digital collections and their worthiness of long-term preservation. Using a seven-point Likert scale, participants assigned a value to each image in terms of its importance to self, family and society. Participants were then asked to explain the reasoning behind their valuations. Public library users and librarians had similar value estimations of the images in the study. This is perhaps the most significant finding of the study, given the importance of collaboration and forming partnerships for building and sustaining community collections and archives.

Integrating optical circuit switches in data-centers is an ongoing research challenge. In recent years, state-of-the-art solutions introduce hybrid packet/circuit architectures for different optical circuit switch technologies, control techniques, and traffic rerouting methods. These solutions...... are based on separated packet and circuit planes which do not have the ability to utilize an optical circuit with flows that do not arrive from or delivered to switches directly connected to the circuit’s end-points.

Use of focus groups in a library's strategic planning process.

Science.gov (United States)

Higa-Moore, Mori Lou; Bunnett, Brian; Mayo, Helen G; Olney, Cynthia A

2002-01-01

The use of focus groups to determine patron satisfaction with library resources and services is extensive and well established. This article demonstrates how focus groups can also be used to help shape the future direction of a library as part of the strategic planning process. By responding to questions about their long-term library and information needs, focus group participants at the University of Texas Southwestern Medical Center at Dallas Library contributed an abundance of qualitative patron data that was previously lacking from this process. The selection and recruitment of these patrons is discussed along with the line of questioning used in the various focus group sessions. Of special interest is the way the authors utilized these sessions to mobilize and involve the staff in creating the library's strategic plan. This was accomplished not only by having staff members participate in one of the sessions but also by sharing the project's major findings with them and instructing them in how these findings related to the library's future. The authors' experience demonstrates that focus groups are an effective strategic planning tool for libraries and emphasizes the need to share information broadly, if active involvement of the staff is desired in both the development and implementation of the library's strategic plan.

Interactive Exhibits Foster Partnership and Engage Diverse Learners at Their Local Libraries

LaConte, K.; Dusenbery, P.; Fitzhugh, G.; Harold, J. B.; Holland, A.

2016-12-01

Learners frequently need to access increasingly complex information to help them understand our changing world. More and more libraries are transforming themselves into places where learners not only access STEM information, but interact with professionals and undertake hands-on learning. Libraries are beginning to position themselves as part of learning ecosystems that contribute to a collective impact on the community. Traveling STEM exhibits are catalyzing these partnerships and engaging students, families, and adults in repeat visits through an accessible venue: their public library. The impact of the STAR Library Education Network's (STAR_Net) Discover Earth: A Century of Change exhibit on partnerships, the circulation of STEM resources, and the engagement of learners was studied by an external evaluation team. The STAR_Net project's summative evaluation utilized mixed methods to investigate project implementation and its outcomes. Methods included pre- and post-exhibit surveys administered to staff from each library that hosted the exhibits; interviews with staff from host libraries; patron surveys; exhibit-related circulation records; web metrics regarding the online STAR_Net community of practice; and site visits. A subset of host libraries recruited professionals, who delivered programming that connected Earth systems science, weather, climate, and conservation themes from the exhibit to local issues. Library patrons improved their knowledge about STEM topics presented in the exhibits and associated programming, and patrons viewing the exhibit reflected the demographics of their communities. In a follow-up survey, patrons reported spending an average of 60 minutes looking at the exhibit over their cumulative visits to the library. In contrast, visitors might visit a museum only once to look at a comparably-sized traveling exhibit due to barriers such as cost and distance. Exhibit host libraries reported an increase in the circulation of Earth science

Student Use of Library Research Guides Following Library Instruction

Directory of Open Access Journals (Sweden)

Mardi Mahaffy

2013-02-01

Full Text Available Librarians often provide students who attend one-shot library instruction sessions with research guides they can refer to once class is over. These guides, whether in paper or electronic form, serve to remind the students of key points and resources addressed during the session. It is unclear, though, if and how students refer to these guides once leaving the classroom. This article reports on the results of two focus groups made up of students who attended a basic library instruction session as part of a survey art course. The students shared how they used a paper and electronic research guide, delivered via LibGuides, and what they would like research guides to contain. The article also suggests directions for further research on the topic.

A Hybrid Energy Sharing Framework for Green Cellular Networks

KAUST Repository

Farooq, Muhammad Junaid

2016-12-09

Cellular operators are increasingly turning towards renewable energy (RE) as an alternative to using traditional electricity in order to reduce operational expenditure and carbon footprint. Due to the randomness in both RE generation and mobile traffic at each base station (BS), a surplus or shortfall of energy may occur at any given time. To increase energy selfreliance and minimize the network’s energy cost, the operator needs to efficiently exploit the RE generated across all BSs. In this paper, a hybrid energy sharing framework for cellular network is proposed, where a combination of physical power lines and energy trading with other BSs using smart grid is used. Algorithms for physical power lines deployment between BSs, based on average and complete statistics of the net RE available, are developed. Afterwards, an energy management framework is formulated to optimally determine the quantities of electricity and RE to be procured and exchanged among BSs, respectively, while considering battery capacities and real-time energy pricing. Three cases are investigated where RE generation is unknown, perfectly known, and partially known ahead of time. Results investigate the time varying energy management of BSs and demonstrate considerable reduction in average energy cost thanks to the hybrid energy sharing scheme.

Zhou, Xiao-Hu; Zhou, Ding-Wu

2009-06-01

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.

A Novel Intensive Distribution Logistics Network Design and Profit Allocation Problem considering Sharing Economy

Directory of Open Access Journals (Sweden)

Mi Gan

2018-01-01

Full Text Available The rapid growth of logistics distribution highlights the problems including the imperfect infrastructure of logistics distribution network, the serious shortage of distribution capacity of each individual enterprise, and the high cost of distribution in China. While the development of sharing economy makes it possible to achieve the integration of whole social logistic resources, big data technology can grasp customer’s logistics demand accurately on the basis of analyzing the customer’s logistics distribution preference, which contributes to the integration and optimization of the whole logistics resources. This paper proposes a kind of intensive distribution logistics network considering sharing economy, which assumes that all the social logistics suppliers build a strategic alliance, and individual idle logistics resources are also used to deal with distribution needs. Analyzing customer shopping behavior by the big data technology to determine customer’s logistics preference on the basis of dividing the customer’s logistics preference into high speed, low cost, and low pollution and then constructing the corresponding objective function model according to different logistics preferences, we obtain the intensive distribution logistics network model and solve it with heuristic algorithm. Furthermore, this paper analyzes the mechanism of interest distribution of the participants in the distribution network and puts forward an improved interval Shapley value method considering both satisfaction and contribution, with case verifying the feasibility and effectiveness of the model. The results showed that, compared with the traditional Shapley method, distribution coefficient calculated by the improved model could be fairer, improve stakeholder satisfaction, and promote the sustainable development of the alliance as well.

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

Science.gov (United States)

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.

Some Ideas and Questions about Meteorological Libraries' Roles at the Internet Age

Science.gov (United States)

Javelle, J.-P.; Cenac, N.

2009-09-01

The roles of specialized libraries have been deeply transformed during the last decade, because of the digital revolution and the changes it has induced on the expectations of library customers. The modernization of the information system of the Météo-France, libraries is in progress. Recent steps include the creation of an on-line photo library and of an institutional open-access repository for all Météo-France scientific publications (http://hal-meteofrance.archives-ouvertes.fr/). The central library has also been involved in the production of the new on-line version of the journal La Météorologie. The new information system will include the Météo-France bibliographic data base, the catalog of libraries and a full-text digital library. This modernization is also the opportunity to respond to growing interest in historical weather data and in the history of meteorology. Météo-France central library was created in 1878 and its collections hold even older documents coming from the Observatoire de Paris and from the Société météorologique de France. A program of digitalization of ancient publications has started with a double perspective : climate data rescue and contribution to history of meteorology. The new information portal will also display a catalog of ancient meteorological instruments. In this modernization process, cooperation with other institutions has been encouraged, for example with CNRS (French National Research Agency) for the HAL institutional repository and the production of one-line version of La Météorologie. The importance of sharing information and expertise with other libraries from libraries networks and professional organisations is worth noting. But several important questions remain to be answered, notably concerning the indexation, the evaluation and the long-term preservation of digital resources. For example, how to make digital collections and services available over time? What is the value of documents or resources

In group-living animals, heterogeneity in individuals' social connections may mediate the sharing of microbial infectious agents. In this regard, the genetic relatedness of individuals' commensal gut bacterium Escherichia coli may be ideal to assess the potential for pathogen transmission through animal social networks. Here we use microbial phylogenetics and population genetics approaches, as well as host social network reconstruction, to assess evidence for the contact-mediated sharing of E. coli among three groups of captively housed rhesus macaques ( Macaca mulatta ), at multiple organizational scales. For each group, behavioral data on grooming, huddling, and aggressive interactions collected for a six-week period were used to reconstruct social network communities via the Data Cloud Geometry (DCG) clustering algorithm. Further, an E. coli isolate was biochemically confirmed and genotypically fingerprinted from fecal swabs collected from each macaque. Population genetics approaches revealed that Group Membership, in comparison to intrinsic attributes like age, sex, and/or matriline membership of individuals, accounted for the highest proportion of variance in E. coli genotypic similarity. Social network approaches revealed that such sharing was evident at the community-level rather than the dyadic level. Specifically, although we found no links between dyadic E. coli similarity and social contact frequencies, similarity was significantly greater among macaques within the same social network communities compared to those across different communities. Moreover, tests for one of our study-groups confirmed that E. coli isolated from macaque rectal swabs were more genotypically similar to each other than they were to isolates from environmentally deposited feces. In summary, our results suggest that among frequently interacting, spatially constrained macaques with complex social relationships, microbial sharing via fecal-oral, social contact-mediated routes may

Surfing for history: dental library and dental school websites.

Science.gov (United States)

Kreinbring, Mary

2007-01-01

Library and academic websites are among the most reliable Internet resources available today. Schools of all types use the Internet as a means of sharing information; and libraries provide broader access to their collections via the Web. For researchers seeking specific, authoritative resources on dental history, library and dental school websites are most helpful in identifying print and online resources, in describing manuscript collections, and in presenting a history of the host institution. A library site often can provide sufficient information online to eliminate the need for an in-person visit to the library. On the other hand, a library site may tantalize the historian with enough information on unique collections that a trip can be justified.

Effects of Knowledge Sharing and Social Presence on the Intention to Continuously Use Social Networking Sites: The Case of Twitter in Korea

Science.gov (United States)

Park, Bong-Won; Lee, Kun Chang

Recent surge of social networking websites in the world supports a widely accepted assumption that people aspires to be recognized online by sharing information with others, perceive enjoyment and keeps to use their social networking site continuously. Different from traditional social networking sites (SNSs) like Cyworld and Facebook, Twitter is famous for its short message and ease of sharing knowledge with others in a prompt manner. Therefore, Twitter is preferred most by many people who seem innovative generically. In this sense, Twitter accumulates its fame as the most influential SNS media among users. However, there is no study to investigate why people holds continuous intention to use the Twitter from the perspective of knowledge-sharing and social presence. To resolve this research issue, this paper adopts six constructs such as personal innovativeness, knowledge-sharing intention, perceived ease of use, perceived enjoyment, social presence, and intention to continuously use. Empirical results with 105 valid questionnaires revealed that the proposed research model is statistically significant, and people's intention to use the Twitter continuously is influenced by social presence, perceived enjoyment, and perceived ease of use.

Full Text Available Among the set goals of improving book consumption in Slovenia the National Culture Program 2004-2007 also includes encouraging the development of network of bookshops and ‘quality’ bookshops, that will be evenly distributed across Slovenia. The program suggests them to be formed within the framework of already existing public cultural institutions. Book consumption in Slovenia has been characterised by poorly developed retail book market and well developed network of public libraries with a high number of book lendings that serves as a substitute for the paperback market as it is known in bigger language communities abroad. Along with surveying the possibilities of directing the libraries towards book marketing (as well, the paper also examines the historical development of commercial publishing companies / bookshops / libraries, existing in Europe in 18th and 19th century and in some places existing side by side with public libraries until the middle of 20th century. The paper shows that the present ratio between bookshops and libraries on some big book markets is different than in Slovenia, as libraries are loosing patrons as a consequence of the growth of big bookshop chains. A characteristic feature of book consumption in Slovenia can be seen in the use of the internet in libraries as well as bookshops. The ‘merging’ of the marketing segment and book lending is to a smaller extent already under way abroad, where large online bookshops encourage libraries by means of provision to act as the mediator in the sale of books. In this way, a library can turn into a bookshop with the help of connections via ISBN numbers, without having to jeopardise their original mission.

CERN looks to library of the future

Participants to the International School on the Digital Library and E-publishing for Science and Technology From 3 to 8 March CERN became an information exhange when it hosted the 'International Spring School on the Digital Library and E-publishing for Science and Technology'. The aim was to share knowledge among the various parties that provide a scientific information service to the CERN users, such as academic libraries, research libraries, publishers, and of course CERN itself. The school involved 50 participants and 17 speakers from countries as far away as Japan and the US. 'The event provided an international forum to advance the state of scientific digital libraries', says the course director Rick Luce, research library director at Los Alamos National Laboratory. 'As a result, we believe this will make a tangible contribution to improving the scholarly resources and electronic services available to physicists throughout Europe and beyond.'

As you all know, training is very important at CERN, and each year the Organization welcomes thousands of students in various areas. However, did you know that it is also possible to learn the profession of Library Assistant (Agent en Information Documentaire - AID)?   For more than 10 years the CERN Library has been providing apprenticeship posts in information science. This apprenticeship lasts three years, during which apprentices share their time between school and work at CERN. The apprenticeship is governed by the laws, regulations and contracts in force in the Canton of Geneva. If they pass the final examinations, apprentices get the Certificat fédéral de capacité suisse (CFC). The library has trained some fifteen apprentices - who have then gone on to work in different institutions in Geneva or elsewhere in Europe - and it is continuing its momentum with a new apprenticeship post, available from September 2012.

Analysis of awareness function showed search aids and knowledge-sharing platforms to be the main facilitating factors. These include services like metadata application, schema, and standards or scholarly portals enabling knowledge-sharing among scholars.Conclusion – This study identified several services offered by these library publishing programs which can be categorized as facilitators under Roosendaal and Geurt’s (1997 four functions of scholarly communication. The majority of the libraries in the study treated library publishing services as part of broader scholarly communication units or initiatives. Digital publishing (registration function was offered by all programs analyzed in the study, while traditional peer-review services (certification function were not. Widely adopted among programs in the study were the use of social networking tools (awareness function and self-publishing (archiving function. The authors recommend developing services that facilitate peer review and assert the need to provide a knowledge-sharing mechanism within the academic community that facilitates the scholarly communication process.

André, Karin; Baird, Julia; Gerger Swartling, Åsa; Vulturius, Gregor; Plummer, Ryan

2017-06-01

To further the understanding of climate change adaptation processes, more attention needs to be paid to the various contextual factors that shape whether and how climate-related knowledge and information is received and acted upon by actors involved. This study sets out to examine the characteristics of forest owners' in Sweden, the information and knowledge-sharing networks they draw upon for decision-making, and their perceptions of climate risks, their forests' resilience, the need for adaptation, and perceived adaptive capacity. By applying the concept of ego-network analysis, the empirical data was generated by a quantitative survey distributed to 3000 private forest owners' in Sweden in 2014 with a response rate of 31%. The results show that there is a positive correlation, even though it is generally weak, between forest owner climate perceptions and (i) network features, i.e. network size and heterogeneity, and (ii) presence of certain alter groups (i.e. network members or actors). Results indicate that forest owners' social networks currently serve only a minimal function of sharing knowledge of climate change and adaptation. Moreover, considering the fairly infrequent contact between respondents and alter groups, the timing of knowledge sharing is important. In conclusion we suggest those actors that forest owners' most frequently communicate with, especially forestry experts providing advisory services (e.g. forest owner associations, companies, and authorities) have a clear role to communicate both the risks of climate change and opportunities for adaptation. Peers are valuable in connecting information about climate risks and adaptation to the actual forest property.

The Impact of Resource Scarcity on Bonding and Bridging Social Capital: the Case of Fishers' Information-Sharing Networks in Loreto, BCS, Mexico

Directory of Open Access Journals (Sweden)

Saudiel Ramirez-Sanchez

2009-06-01

Full Text Available Fishers often rely on their social capital to cope with resource fluctuations by sharing information on the abundance and location of fish. Drawing on research in seven coastal fishing communities in Loreto, Baja California Sur, Mexico, we examine the effect of resource scarcity on the bonding, bridging, and linking social-capital patterns of fishers' information-sharing networks. We found that: (1 fishers' information sharing is activated in response to varying ecological conditions; (2 resource scarcity is an ambiguous indicator of the extent to which fishers share information on the abundance and location of fish within and between communities; (3 information sharing is based on trust and occurs through kinship, friendship, and acquaintance social relations; (4 friendship ties play a key and flexible role in fishers' social networks within and between communities; (5 overall, the composition of fishers' social networks follows a friendship>kinship>acquaintance order of importance; and (6 the function of social ties, internal conflict, and settlement histories moderate the effects of resource scarcity on fishers' social capital. We conclude by arguing that the livelihoods of fishers from Loreto have adaptive capacity for dealing with fish fluctuations but little or no proactive resilience to address resource-management issues.

An efficient hybrid protection scheme with shared/dedicated backup paths on elastic optical networks

Directory of Open Access Journals (Sweden)

Nogbou G. Anoh

2017-02-01

Full Text Available Fast recovery and minimum utilization of resources are the two main criteria for determining the protection scheme quality. We address the problem of providing a hybrid protection approach on elastic optical networks under contiguity and continuity of available spectrum constraints. Two main hypotheses are used in this paper for backup paths computation. In the first case, it is assumed that backup paths resources are dedicated. In the second case, the assumption is that backup paths resources are available shared resources. The objective of the study is to minimize spectrum utilization to reduce blocking probability on a network. For this purpose, an efficient survivable Hybrid Protection Lightpath (HybPL algorithm is proposed for providing shared or dedicated backup path protection based on the efficient energy calculation and resource availability. Traditional First-Fit and Best-Fit schemes are employed to search and assign the available spectrum resources. The simulation results show that HybPL presents better performance in terms of blocking probability, compared with the Minimum Resources Utilization Dedicated Protection (MRU-DP algorithm which offers better performance than the Dedicated Protection (DP algorithm.

Developing European Library Services in Changing Times

Paul Ayris

2012-04-01

Full Text Available The purpose of this article is to explain what academic and national libraries can do to continue to offer services and facilities at a time of economic difficulties. It identifies a number of methodologies and opportunities that are open to libraries and takes the view that it is never wise to waste a good crisis, because all threats are really opportunities in disguise. The kernel of this paper was delivered at the 10th Anniversary special EISZ Consortium Members’ Meeting on 2 December 2011, in Budapest, Hungary. It builds on an earlier talk delivered in Thessaloniki, Greece, on 14–15 November 2011 at the 20th Pan-Hellenic Academic Libraries Conference, entitled ‘Academic Libraries and Financial Crisis: Strategies for Survival’. Both these presentations are available in UCL Discovery. This article draws on themes used in both presentations, and introduces a new one on the topic of copyright reform. The article looks at the initial economic context for European research libraries and then examines ways in which libraries can tackle the threats which the current financial crisis poses. Joint procurement is one way in which libraries can achieve value for money, and the paper examines the role of JISC Collections in the UK. Innovation through collaboration and shared services are also ways in which libraries can innovate/make savings in a cost-effective way by sharing the burden of costs around the partnership. The paper gives two examples: one which is now well established, the DART-Europe portal for Open Access e-theses; and one which is in the early stages of being discussed — a cloud-based solution for true collaborative cataloguing amongst the UK’s research and national libraries. The European Research Area (ERA and the contributions that libraries can make to this infrastructure through innovative EU project funding are analysed in some detail by looking at LIBER’s EU project portfolio. Finally, change and growth can come

Health libraries have changed over the past fifteen years in the format of the information they provide. This is driven by developments in technology. To conduct a survey of NHS health libraries in the United Kingdom in order to summarise how mobile technologies are being used, how they are promoted and how they are delivered, highlighting good practice and solutions to issues. An online survey was carried out in 2013 and sent to academic and NHS web-based discussion lists. There were 199 responses. Main replies were from large Acute Hospital Trusts. Only 18% of respondents had conducted research into use of mobile technology (MT) within their Trust. Forty per cent of Trusts offered clinical point of care tools, 29% mobile catalogues, and 30% had mobile enabled web sites. Libraries utilised third-party partnerships rather than develop their own applications or tools. Seventy per cent of Trusts promoted new MT services via e-mail. Network restrictions were the main barrier to development as well as finance and expertise. Uptake and development of MT is sporadic and driven by individuals. There is an opportunity for collaboration and sharing resources and expertise. There are benefits to adopting user-friendly resources. © 2015 Health Libraries Group.

Knowledge Management in healthcare libraries: the current picture.

Knowledge management has seen something of a resurgence in attention amongst health librarians recently. Of course it has never ceased to exist, but now many library staff are becoming more involved in organisational knowledge management, and positioning themselves as key players in the sphere. No single model of knowledge management is proliferating, but approaches that best fit the organisation's size, structure and culture, and a blending of evidence based practice and knowledge sharing. Whatever it is called and whatever models are used, it's clear that for librarians and information professionals, the importance of putting knowledge and evidence into practice, sharing knowledge well and capturing it effectively, are still what we will continue to do. © 2017 Health Libraries Group.

Secure and Privacy-Preserving Data Sharing and Collaboration in Mobile Healthcare Social Networks of Smart Cities

Directory of Open Access Journals (Sweden)

Qinlong Huang

2017-01-01

Full Text Available Mobile healthcare social networks (MHSN integrated with connected medical sensors and cloud-based health data storage provide preventive and curative health services in smart cities. The fusion of social data together with real-time health data facilitates a novel paradigm of healthcare big data analysis. However, the collaboration of healthcare and social network service providers may pose a series of security and privacy issues. In this paper, we propose a secure health and social data sharing and collaboration scheme in MHSN. To preserve the data privacy, we realize secure and fine-grained health data and social data sharing with attribute-based encryption and identity-based broadcast encryption techniques, respectively, which allows patients to share their private personal data securely. In order to achieve enhanced data collaboration, we allow the healthcare analyzers to access both the reencrypted health data and the social data with authorization from the data owner based on proxy reencryption. Specifically, most of the health data encryption and decryption computations are outsourced from resource-constrained mobile devices to a health cloud, and the decryption of the healthcare analyzer incurs a low cost. The security and performance analysis results show the security and efficiency of our scheme.

PhysiomeSpace: digital library service for biomedical data.

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.

Cloud Computing in KAUST Library: Beyond Remote Hosting

KAUST Repository

Yu, Yi

2013-12-01

Enterprise computing is the key strategic approach for KAUST to build its modern IT landscape. In such a strategic direction and technical environment, the library tries to establish library technology by catching new trends which help to make the library more efficient and sufficient. This paper focuses on the cloud computing development in the KAUST library, by using real world scenarios and first-hand experiences to describe what cloud computing means for KAUST library. It addresses the difficulties that were met by the library during the implementation process, how cloud computing affects the functional performance and work procedure of the library, how it impacts the style and modal of the library’s technical service and systems administration, how it changes the relationships and cooperation among the involved players (the library, campus IT and vendors), and what the benefits and disadvantages are. The story of cloud computing at KAUST will share the knowledge and lessons that the KAUST library learnt during its development, and will also point out the future direction of cloud computing at KAUST.

Research support services to small and medium enterprises by university libraries in Uganda: An entrepreneurial and innovation strategy

2017-10-01

Objectives: The objectives of this study were to: investigate how university libraries in Uganda are managing the universities’ research output; find out how the research output is disseminated to SMEs for their entrepreneurial activities, to understand how SMEs access and use R&I information for their entrepreneurial programmes; and propose feasible strategies of how best university libraries can re-engineer the dissemination of the research output for use by SMEs in their entrepreneurial endeavours. Method: The study used document analysis which is a qualitative data collection method. Empirical literature related to the research variables of the study was reviewed through systematic searching of manual and electronic documents on how university libraries treat their R&I information in relation to entrepreneurship. Results: The findings demonstrate that university libraries can re-engineer their R&I information services for SMEs through: repackaging R&I information in formats and languages easily accessible by SMEs; creating informal social networks for information sharing among SMEs; creation of R&I information library corners; University Library Consortia advocating for this concept; periodical announcements of new R&I information in the library through emails to SMEs; organising SME days in the library; creation of SME pages on the library website; conducting information literacy training sessions for SME entrepreneurs; and adding this concept in the library and information science curricular. Conclusion: This article discusses how university libraries, from a developing country context such as Uganda, can re-engineer research output for SMEs and use it to develop innovative solutions that can contribute positively towards SDGs and the social economic transformation of Africa at large.

A rural virtual health sciences library project: research findings with implications for next generation library services.

Science.gov (United States)

Richwine, M P; McGowan, J J

2001-01-01

The Shared Hospital Electronic Library of Southern Indiana (SHELSI) research project was designed to determine whether access to a virtual health sciences library and training in its use would support medical decision making in rural southern Indiana and achieve the same level of impact seen by targeted information services provided by health sciences librarians in urban hospitals. Based on the results of a needs assessment, a virtual medical library was created; various levels of training were provided. Virtual library users were asked to complete a Likert-type survey, which included questions on intent of use and impact of use. At the conclusion of the project period, structured interviews were conducted. Impact of the virtual health sciences library showed a strong correlation with the impact of information provided by health sciences librarians. Both interventions resulted in avoidance of adverse health events. Data collected from the structured interviews confirmed the perceived value of the virtual library. While librarians continue to hold a strong position in supporting information access for health care providers, their roles in the information age must begin to move away from providing information toward selecting and organizing knowledge resources and instruction in their use.

Spectrum Sharing Based on a Bertrand Game in Cognitive Radio Sensor Networks

Directory of Open Access Journals (Sweden)

Biqing Zeng

2017-01-01

Full Text Available In the study of power control and allocation based on pricing, the utility of secondary users is usually studied from the perspective of the signal to noise ratio. The study of secondary user utility from the perspective of communication demand can not only promote the secondary users to meet the maximum communication needs, but also to maximize the utilization of spectrum resources, however, research in this area is lacking, so from the viewpoint of meeting the demand of network communication, this paper designs a two stage model to solve spectrum leasing and allocation problem in cognitive radio sensor networks (CRSNs. In the first stage, the secondary base station collects the secondary network communication requirements, and rents spectrum resources from several primary base stations using the Bertrand game to model the transaction behavior of the primary base station and secondary base station. The second stage, the subcarriers and power allocation problem of secondary base stations is defined as a nonlinear programming problem to be solved based on Nash bargaining. The simulation results show that the proposed model can satisfy the communication requirements of each user in a fair and efficient way compared to other spectrum sharing schemes.

Software-Defined Networks as a Stage of the Network Technology Evolution

Directory of Open Access Journals (Sweden)

A. A. Krasotin

2013-01-01

Full Text Available The authors of the article focus on the concept of a software defined network. In the beginning, the brief historical account is given concerning software defined networks as a scientific concept, its formation and technological and scientific meaning. The software defined network concept is treated in the article not as the final state-of-the-art in networking, but rather as a possible step and direction in the development of a networking paradigm. The article touches on pros and cons as well of the software defined networking and gives an account of possible stages of development of this technology in the context of other technologies, considering its hybrid with MPLS, as an example. OpenFlow protocol constitutes the main part of the article. The authors further discuss various kinds of existing libraries realizing programmable management routines for a software defined network using OpenFlow. All of these libraries provide API for building modular applications for software defined network management. Touching on practical side of implementation the results of comparative tests of throughput and latency, achieved with these libraries are shown.

Hospital librarians must ensure they are contributing positively to the organization\\'s goals and are proactive in meeting user needs while making the best use of scarce resources. Therefore, effective communication with library clients is essential. Client audits are useful tools, but response rates are often poor as the audit can get lost in the overwhelming amount of unsolicited mail received by clinical practitioners, who quickly become expert at selecting and culling. This column shares lessons learned through conducting the audit, highlights key findings from the audit itself, and examines ways to use the audit process to promote and develop a library\\'s services.

A new scripting library for modeling flow and transport in fractured rock with channel networks

Science.gov (United States)

Dessirier, Benoît; Tsang, Chin-Fu; Niemi, Auli

2018-02-01

Deep crystalline bedrock formations are targeted to host spent nuclear fuel owing to their overall low permeability. They are however highly heterogeneous and only a few preferential paths pertaining to a small set of dominant rock fractures usually carry most of the flow or mass fluxes, a behavior known as channeling that needs to be accounted for in the performance assessment of repositories. Channel network models have been developed and used to investigate the effect of channeling. They are usually simpler than discrete fracture networks based on rock fracture mappings and rely on idealized full or sparsely populated lattices of channels. This study reexamines the fundamental parameter structure required to describe a channel network in terms of groundwater flow and solute transport, leading to an extended description suitable for unstructured arbitrary networks of channels. An implementation of this formalism in a Python scripting library is presented and released along with this article. A new algebraic multigrid preconditioner delivers a significant speedup in the flow solution step compared to previous channel network codes. 3D visualization is readily available for verification and interpretation of the results by exporting the results to an open and free dedicated software. The new code is applied to three example cases to verify its results on full uncorrelated lattices of channels, sparsely populated percolation lattices and to exemplify the use of unstructured networks to accommodate knowledge on local rock fractures.

Since, the evolution of distributed operating system, distributed file system is come out to be important part in operating system. P2P is a reliable way in Distributed Operating System for file sharing. It was introduced in 1999, later it became a high research interest topic. Peer to Peer network is a type of network, where peers share network workload and other load related tasks. A P2P network can be a period of time connection, where a bunch of computers connected by a USB (Universal Serial Bus) port to transfer or enable disk sharing i.e. file sharing. Currently P2P requires special network that should be designed in P2P way. Nowadays, there is a big influence of browsers in our life. In this project we are going to study of file sharing mechanism in distributed operating system in web browsers, where we will try to find performance bottlenecks which our research will going to be an improvement in file sharing by performance and scalability in distributed file systems. Additionally, we will discuss the scope of Web Torrent file sharing and free-riding in peer to peer networks.

Sharing programming resources between Bio* projects through remote procedure call and native call stack strategies.

Prins, Pjotr; Goto, Naohisa; Yates, Andrew; Gautier, Laurent; Willis, Scooter; Fields, Christopher; Katayama, Toshiaki

2012-01-01

Open-source software (OSS) encourages computer programmers to reuse software components written by others. In evolutionary bioinformatics, OSS comes in a broad range of programming languages, including C/C++, Perl, Python, Ruby, Java, and R. To avoid writing the same functionality multiple times for different languages, it is possible to share components by bridging computer languages and Bio* projects, such as BioPerl, Biopython, BioRuby, BioJava, and R/Bioconductor. In this chapter, we compare the two principal approaches for sharing software between different programming languages: either by remote procedure call (RPC) or by sharing a local call stack. RPC provides a language-independent protocol over a network interface; examples are RSOAP and Rserve. The local call stack provides a between-language mapping not over the network interface, but directly in computer memory; examples are R bindings, RPy, and languages sharing the Java Virtual Machine stack. This functionality provides strategies for sharing of software between Bio* projects, which can be exploited more often. Here, we present cross-language examples for sequence translation, and measure throughput of the different options. We compare calling into R through native R, RSOAP, Rserve, and RPy interfaces, with the performance of native BioPerl, Biopython, BioJava, and BioRuby implementations, and with call stack bindings to BioJava and the European Molecular Biology Open Software Suite. In general, call stack approaches outperform native Bio* implementations and these, in turn, outperform RPC-based approaches. To test and compare strategies, we provide a downloadable BioNode image with all examples, tools, and libraries included. The BioNode image can be run on VirtualBox-supported operating systems, including Windows, OSX, and Linux.

The University of Illinois Library of the Health Sciences at Rockford (LHS-Rockford) long has honored a commitment to serving the health information needs of the greater Rockford community. Utilization data collected over the past five years indicate that approximately 50% of reference transactions involve persons not affiliated with the university. In early 1994, LHS-Rockford submitted a proposal to the Northern Illinois Library System (NILS), a multitype system spanning twelve counties in northwestern Illinois, asking to serve as a resource library for improving medical and health information services provided by the 138 NILS member libraries. The NILS funded this pilot project as part of an effort to implement a new strategic plan, which encouraged member libraries to form networks to provide reference back-up service. LHS-Rockford acquired InfoTrac's Health Reference Center, a consumer health information database, and set up a dedicated workstation near the information and circulation desk. Referral guidelines were established and the project was promoted among NILS member libraries. Activities were documented in order to track project success in terms of referrals and outcomes. The demonstration project was very successful, and it proves public consumers seeking health information can benefit greatly from this type of cooperative arrangement.

Centralized and federated models for sharing data in research networks currently exist. To build multivariate data analysis for centralized networks, transfer of patient-level data to a central computation resource is necessary. The authors implemented distributed multivariate models for federated networks in which patient-level data is kept at each site and data exchange policies are managed in a study-centric manner. The objective was to implement infrastructure that supports the functionality of some existing research networks (e.g., cohort discovery, workflow management, and estimation of multivariate analytic models on centralized data) while adding additional important new features, such as algorithms for distributed iterative multivariate models, a graphical interface for multivariate model specification, synchronous and asynchronous response to network queries, investigator-initiated studies, and study-based control of staff, protocols, and data sharing policies. Based on the requirements gathered from statisticians, administrators, and investigators from multiple institutions, the authors developed infrastructure and tools to support multisite comparative effectiveness studies using web services for multivariate statistical estimation in the SCANNER federated network. The authors implemented massively parallel (map-reduce) computation methods and a new policy management system to enable each study initiated by network participants to define the ways in which data may be processed, managed, queried, and shared. The authors illustrated the use of these systems among institutions with highly different policies and operating under different state laws. Federated research networks need not limit distributed query functionality to count queries, cohort discovery, or independently estimated analytic models. Multivariate analyses can be efficiently and securely conducted without patient-level data transport, allowing institutions with strict local data storage

Martínez-García, Alicia; Moreno-Conde, Alberto; Jódar-Sánchez, Francisco; Leal, Sandra; Parra, Carlos

2013-12-01

Social networks applied through Web 2.0 tools have gained importance in health domain, because they produce improvements on the communication and coordination capabilities among health professionals. This is highly relevant for multimorbidity patients care because there is a large number of health professionals in charge of patient care, and this requires to obtain clinical consensus in their decisions. Our objective is to develop a tool for collaborative work among health professionals for multimorbidity patient care. We describe the architecture to incorporate decision support functionalities in a social network tool to enable the adoption of shared decisions among health professionals from different care levels. As part of the first stage of the project, this paper describes the results obtained in a pilot study about acceptance and use of the social network component in our healthcare setting. At Virgen del Rocío University Hospital we have designed and developed the Shared Care Platform (SCP) to provide support in the continuity of care for multimorbidity patients. The SCP has two consecutively developed components: social network component, called Clinical Wall, and Clinical Decision Support (CDS) system. The Clinical Wall contains a record where health professionals are able to debate and define shared decisions. We conducted a pilot study to assess the use and acceptance of the SCP by healthcare professionals through questionnaire based on the theory of the Technology Acceptance Model. In March 2012 we released and deployed the SCP, but only with the social network component. The pilot project lasted 6 months in the hospital and 2 primary care centers. From March to September 2012 we created 16 records in the Clinical Wall, all with a high priority. A total of 10 professionals took part in the exchange of messages: 3 internists and 7 general practitioners generated 33 messages. 12 of the 16 record (75%) were answered by the destination health professionals

Hu, Susan C; Kuo, Hsien-Wen

2016-03-01

The World Health Organization (WHO) Healthy Cities (HC) projects are the best known of the settings-based approaches to health promotion. They engage local governments in health development through a process of political commitment, institutional change, capacity-building, partnership-based planning and innovative projects. Many cities have promoted HC projects in Taiwan since 2002. In 2008, the Taiwan Alliance for Healthy Cities (TAHC) was launched to assist local governments in effectively establishing, operating and promoting HC projects. In this article, we share our experiences of establishing a platform and network to promote the HC program in Taiwan. Based on individual city profiles and governance in Taiwan, the TAHC developed a well-organized framework and model to encourage strong leadership in local governments and to promote participation and engagement in their communities. In the last 6 years, leaders from Taiwan's local governments in HC networks have integrated the HC concepts into their governance models, actively engaging and combining various resources with practical expertise and private sectors. The network of health in Taiwan allows each city to develop its unique perspective on the HC projects. Using this method, not only local government meets its needs, but also increases governance efficiency and effectiveness, resulting in the promotion of its citizens' overall sustainable urban health development. This HC network in Taiwan has partnerships with government and non-governmental organizations (NGOs), with academic support and citizen involvement, a dynamic data collection system and demonstrated leadership in the sharing of information in the Asian region. © The Author(s) 2016.

2018-03-02

The recent establishment of cloud computing, high-throughput networking, and more versatile web standards and browsers has led to a renewed interest in web-based applications. While traditionally big data has been the domain of optimized desktop and server applications, it is now possible to store vast amounts of data and perform the necessary calculations offsite in cloud storage and computing providers, with the results visualized in a high-quality cross-platform interface via a web browser. There are number of emerging platforms for cloud-based mass spectrometry data analysis; however, there is limited pre-existing code accessible to web developers, especially for those that are constrained to a shared hosting environment where Java and C applications are often forbidden from use by the hosting provider. To remedy this, we provide an open-source mass spectrometry library for one of the most commonly used web development languages, PHP. Our new library, phpMs, provides objects for storing and manipulating spectra and identification data as well as utilities for file reading, file writing, calculations, peptide fragmentation, and protein digestion as well as a software interface for controlling search engines. We provide a working demonstration of some of the capabilities at http://pgb.liv.ac.uk/phpMs .

A rural virtual health sciences library project: research findings with implications for next generation library services*

Science.gov (United States)

Richwine, Margaret (Peggy); McGowan, Julie J.

2001-01-01

Purpose: The Shared Hospital Electronic Library of Southern Indiana (SHELSI) research project was designed to determine whether access to a virtual health sciences library and training in its use would support medical decision making in rural southern Indiana and achieve the same level of impact seen by targeted information services provided by health sciences librarians in urban hospitals. Methods: Based on the results of a needs assessment, a virtual medical library was created; various levels of training were provided. Virtual library users were asked to complete a Likert-type survey, which included questions on intent of use and impact of use. At the conclusion of the project period, structured interviews were conducted. Results: Impact of the virtual health sciences library showed a strong correlation with the impact of information provided by health sciences librarians. Both interventions resulted in avoidance of adverse health events. Data collected from the structured interviews confirmed the perceived value of the virtual library. Conclusion: While librarians continue to hold a strong position in supporting information access for health care providers, their roles in the information age must begin to move away from providing information toward selecting and organizing knowledge resources and instruction in their use.

Current situation and discussion of acquisition work in professional libraries

International Nuclear Information System (INIS)

Lu Yan; Xin Pingping

2010-01-01

The acquisition work in professional libraries is an important part of library work, and faces enormous challenges at this stage. For the status quo of the acquisition work in professional libraries, we should develop effective acquisition principles to ensure the integrity of our professional library's collection and systematic literature, and to provide more effective protection for relevant research work. We need reasonable arrangements for the procurement of books with limited funding to avoid the waste of funds. We should use the network, to actively develop the procurement channels, and to establish accurate and reliable systematic network of information resources for the reader. We need to consciously cultivate and improve the professional competence of acquisition staff, to meet the requirement of the acquisition staff in the new situation. We should carry out knowledge management in professional library, to form a competitive 'knowledge resources'. For information research, technical personnel, and scientific researchers, we provide effective information services in time, and carry out personalized services. (authors)

Shared genetic regulatory networks for cardiovascular disease and type 2 diabetes in multiple populations of diverse ethnicities in the United States.

2017-09-01

Full Text Available Cardiovascular diseases (CVD and type 2 diabetes (T2D are closely interrelated complex diseases likely sharing overlapping pathogenesis driven by aberrant activities in gene networks. However, the molecular circuitries underlying the pathogenic commonalities remain poorly understood. We sought to identify the shared gene networks and their key intervening drivers for both CVD and T2D by conducting a comprehensive integrative analysis driven by five multi-ethnic genome-wide association studies (GWAS for CVD and T2D, expression quantitative trait loci (eQTLs, ENCODE, and tissue-specific gene network models (both co-expression and graphical models from CVD and T2D relevant tissues. We identified pathways regulating the metabolism of lipids, glucose, and branched-chain amino acids, along with those governing oxidation, extracellular matrix, immune response, and neuronal system as shared pathogenic processes for both diseases. Further, we uncovered 15 key drivers including HMGCR, CAV1, IGF1 and PCOLCE, whose network neighbors collectively account for approximately 35% of known GWAS hits for CVD and 22% for T2D. Finally, we cross-validated the regulatory role of the top key drivers using in vitro siRNA knockdown, in vivo gene knockout, and two Hybrid Mouse Diversity Panels each comprised of >100 strains. Findings from this in-depth assessment of genetic and functional data from multiple human cohorts provide strong support that common sets of tissue-specific molecular networks drive the pathogenesis of both CVD and T2D across ethnicities and help prioritize new therapeutic avenues for both CVD and T2D.

National and International Library Collaboration: Necessity, Advantages

Directory of Open Access Journals (Sweden)

Timothy Mark

2007-11-01

Full Text Available The advantages of cooperation between research library associations can be demonstrated quite clearly. Where cooperation becomes essential is where there is a common cause to champion or an initiative to pursue for the common good. Thanks in part to the power of information communications technology, research is becoming increasingly international in scope. The members of interdisciplinary and multidisciplinary research teams are frequently drawn from across the world. Correspondingly, scholarly publishing (especially in medicine and the sciences is dominated by a few multinational publishers. In this context, issues that play a vital role in global scholarly communication - such as copyright, journal pricing, the managing of datasets, digital preservation and open access - are issues for the research library community everywhere in the world. Certainly there are many challenges at the local or regional level. However there are definite roles that research library associations can play most effectively at the national or international level. It is clear that by sharing expertise, building partnerships and alliances, it is possible to address common issues much more effectively than when working alone. What is special is that potentially the most powerful form of cooperation is advocacy at the national and international levels. It is essential for research library associations to work together at the political level to move their agenda forward. Examples are lobbying about copyright legislation (nationally, or within the EC or at WIPO; or promoting the cause of Open Access. The unique value of LIBER is to provide a forum and a platform for European research library associations to explore and benefit from cooperation and their shared strength.

Cross-layer shared protection strategy towards data plane in software defined optical networks

Science.gov (United States)

Xiong, Yu; Li, Zhiqiang; Zhou, Bin; Dong, Xiancun

2018-04-01

In order to ensure reliable data transmission on the data plane and minimize resource consumption, a novel protection strategy towards data plane is proposed in software defined optical networks (SDON). Firstly, we establish a SDON architecture with hierarchical structure of data plane, which divides the data plane into four layers for getting fine-grained bandwidth resource. Then, we design the cross-layer routing and resource allocation based on this network architecture. Through jointly considering the bandwidth resource on all the layers, the SDN controller could allocate bandwidth resource to working path and backup path in an economical manner. Next, we construct auxiliary graphs and transform the shared protection problem into the graph vertex coloring problem. Therefore, the resource consumption on backup paths can be reduced further. The simulation results demonstrate that the proposed protection strategy can achieve lower protection overhead and higher resource utilization ratio.

3D High Resolution Mesh Deformation Based on Multi Library Wavelet Neural Network Architecture

Science.gov (United States)

Dhibi, Naziha; Elkefi, Akram; Bellil, Wajdi; Amar, Chokri Ben

2016-12-01

This paper deals with the features of a novel technique for large Laplacian boundary deformations using estimated rotations. The proposed method is based on a Multi Library Wavelet Neural Network structure founded on several mother wavelet families (MLWNN). The objective is to align features of mesh and minimize distortion with a fixed feature that minimizes the sum of the distances between all corresponding vertices. New mesh deformation method worked in the domain of Region of Interest (ROI). Our approach computes deformed ROI, updates and optimizes it to align features of mesh based on MLWNN and spherical parameterization configuration. This structure has the advantage of constructing the network by several mother wavelets to solve high dimensions problem using the best wavelet mother that models the signal better. The simulation test achieved the robustness and speed considerations when developing deformation methodologies. The Mean-Square Error and the ratio of deformation are low compared to other works from the state of the art. Our approach minimizes distortions with fixed features to have a well reconstructed object.

EPPS: Efficient and Privacy-Preserving Personal Health Information Sharing in Mobile Healthcare Social Networks.

Jiang, Shunrong; Zhu, Xiaoyan; Wang, Liangmin

2015-09-03

Mobile healthcare social networks (MHSNs) have emerged as a promising next-generation healthcare system, which will significantly improve the quality of life. However, there are many security and privacy concerns before personal health information (PHI) is shared with other parities. To ensure patients' full control over their PHI, we propose a fine-grained and scalable data access control scheme based on attribute-based encryption (ABE). Besides, policies themselves for PHI sharing may be sensitive and may reveal information about underlying PHI or about data owners or recipients. In our scheme, we let each attribute contain an attribute name and its value and adopt the Bloom filter to efficiently check attributes before decryption. Thus, the data privacy and policy privacy can be preserved in our proposed scheme. Moreover, considering the fact that the computational cost grows with the complexity of the access policy and the limitation of the resource and energy in a smart phone, we outsource ABE decryption to the cloud while preventing the cloud from learning anything about the content and access policy. The security and performance analysis is carried out to demonstrate that our proposed scheme can achieve fine-grained access policies for PHI sharing in MHSNs.

Overlaid cellular technology has been considered as a promising candidate to enhance the capacity and extend the coverage of cellular networks, particularly indoors. The deployment of small cells (e.g. femtocells and/or picocells) in an overlaid setup is expected to reduce the operational power and to function satisfactorily with the existing cellular architecture. Among the possible deployments of small-cell access points is to manage many of them to serve specific spatial locations, while reusing the available spectrum universally. This contribution considers the aforementioned scenario with the objective to serve as many active users as possible when the available downlink spectrum is overloaded. The case study is motivated by the importance of realizing universal resource sharing in overlaid networks, while reducing the load of distributing available resources, satisfying downlink multi-channel assignment, controlling the aggregate level of interference, and maintaining desired design/operation requirements. These objectives need to be achieved in distributed manner in each spatial space with as low processing load as possible when the feedback links are capacity-limited, multiple small-cell access points can be shared, and data exchange between access points can not be coordinated. This contribution is summarized as follows. An adaptive downlink multi-channel assignment scheme when multiple co-channel and shared small-cell access points are allocated to serve active users is proposed. It is assumed that the deployed access points employ isotropic antenna arrays of arbitrary sizes, operate using the open-access strategy, and transmit on shared physical channels simultaneously. Moreover, each active user can be served by a single transmit channel per each access point at a time, and can sense the concurrent interference level associated with each transmit antenna channel non-coherently. The proposed scheme aims to identify a suitable subset of transmit channels

Challenges to Participation in the Sharing Economy: The Case of Local Online Peer-to-Peer Exchange in a Single Parents’ Network

Full Text Available This paper depicts an initiative to deploy an online peer-to-peer exchange system for a community network of single parents – a group of people in need of goods, services, and social support in their local neighborhoods. We apply participant observation and semi-structured interviews to uncover key issues that can hinder the emergence of sharing practices in local community networks of this type. Our study illustrates how pressures related to single parenthood can impede opportunities to engage in peer-to-peer exchange, even when community members view the social and material benefits of participation as desirable and necessary. This complicates the prevalent narrative that local peer-to-peer exchange systems are an accessible and convenient alternative to traditional markets. Moreover, we discuss our collaboration with the community as well as the developers of the sharing platform, highlighting the challenges of user-centered design in the sharing economy.

Transcription factors with programmable DNA-binding specificity constitute valuable tools for the design of orthogonal gene regulatory networks for synthetic biology. Transcription activator-like effectors (TALEs), as natural transcription regulators, were used to design, build, and test libraries of synthetic TALE-activated promoters (STAPs) that show a broad range of expression levels in plants. In this chapter, we present protocols for the construction of artificial TALEs and corresponding STAPs.

Developing new copyright services in academic libraries

Inga-Lill Nilsson

2016-03-01

Full Text Available This article discusses the role of academic librarians in handling copyright-related issues, including their required skills and knowledge about copyright. IP (intellectual property issues have become more important in publishing and in accessing and reusing scientific research, and new technology and delivery mechanisms have increased copyright issues. Due to the complications and general confusion about copyright, there is a growing need for official support. Academic librarians often have only an informal mandate to work in this area and therefore lack confidence, sufficient knowledge and training. They seldom have the authority to work with copyright education in a formalized way. Legitimacy can be achieved by collaborating with other university units with an interest in copyright. Co-operation with other libraries and library organizations is also an important way to share experiences and increase knowledge about copyright. Libraries can contribute to improved IP services once they have established that copyright is a library matter, found tools for copyright education and embedded these activities into library routines.

Anaphe - OO Libraries and Tools for Data Analysis

CERN Document Server

Couet, O; Molnar, Z; Moscicki, J T; Pfeiffer, A; Sang, M

2001-01-01

The Anaphe project is an ongoing effort to provide an Object Oriented software environment for data analysis in HENP experiments. A range of commercial and public domain libraries is used to cover basic functionalities; on top of these libraries a set of HENP-specific C++ class libraries for histogram management, fitting, plotting and ntuple-like data analysis has been developed. In order to comply with the user requirements for a command-line driven tool, we have chosen to use a scripting language (Python) as the front-end for a data analysis tool. The loose coupling provided by the consequent use of (AIDA compliant) Abstract Interfaces for each component in combination with the use of shared libraries for their implementation provides an easy integration of existing libraries into modern scripting languages thus allowing for rapid application development. This integration is simplified even further using a specialised toolkit (SWIG) to create "shadow classes" for the Python language, which map the definitio...

Data-sharing protocol: A prototype implementation

International Nuclear Information System (INIS)

Gibney, T.; Greenwood, D.

1992-12-01

This paper describes a client/server communication protocol which will allow physicists to access data from cooperating remote experiments. Special low-level ''client'' software within the user's ''home'' data-access library formulates a request for data from the remote experiment. This request is sent over a network to a server at the remote site. The server has specific knowledge about the location and format of the requested data. The server gets the data and sends it over the network to the requesting client, which reformats the data according to the local library's conventions. Our prototype is being developed to suppose remote access to data from ATF, PBX, and micro Vax data from Tore-Supra. We have attempted to create a flexible design which should accommodate data from other experiments as well

Full Text Available The Chronopolis Digital Preservation Initiative, one of the Library of Congress’ latest efforts to collect and preserve at-risk digital information, has completed its first year of service as a multi-member partnership to meet the archival needs of a wide range of domains.Chronopolis is a digital preservation data grid framework developed by the San Diego Supercomputer Center (SDSC at UC San Diego, the UC San Diego Libraries (UCSDL, and their partners at the National Center for Atmospheric Research (NCAR in Colorado and the University of Maryland's Institute for Advanced Computer Studies (UMIACS.Chronopolis addresses a critical problem by providing a comprehensive model for the cyberinfrastructure of collection management, in which preserved intellectual capital is easily accessible, and research results, education material, and new knowledge can be incorporated smoothly over the long term. Integrating digital library, data grid, and persistent archive technologies, Chronopolis has created trusted environments that span academic institutions and research projects, with the goal of long-term digital preservation.A key goal of the Chronopolis project is to provide cross-domain collection sharing for long-term preservation. Using existing high-speed educational and research networks and mass-scale storage infrastructure investments, the partnership is leveraging the data storage capabilities at SDSC, NCAR, and UMIACS to provide a preservation data grid that emphasizes heterogeneous and highly redundant data storage systems.In this paper we will explore the major themes within Chronopolis, including:a The philosophy and theory behind a nationally federated data grid for preservation. b The core tools and technologies used in Chronopolis. c The metadata schema that is being developed within Chronopolis for all of the data elements. d Lessons learned from the first year of the project.e Next steps in digital preservation using Chronopolis: how we

SPECIAL LIBRARIES OF FRAGMENTS OF ALGORITHMIC NETWORKS TO AUTOMATE THE DEVELOPMENT OF ALGORITHMIC MODELS

Full Text Available Summary. The concept of algorithmic models appeared from the algorithmic approach in which the simulated object, the phenomenon appears in the form of process, subject to strict rules of the algorithm, which placed the process of operation of the facility. Under the algorithmic model is the formalized description of the scenario subject specialist for the simulated process, the structure of which is comparable with the structure of the causal and temporal relationships between events of the process being modeled, together with all information necessary for its software implementation. To represent the structure of algorithmic models used algorithmic network. Normally, they were defined as loaded finite directed graph, the vertices which are mapped to operators and arcs are variables, bound by operators. The language of algorithmic networks has great features, the algorithms that it can display indifference the class of all random algorithms. In existing systems, automation modeling based on algorithmic nets, mainly used by operators working with real numbers. Although this reduces their ability, but enough for modeling a wide class of problems related to economy, environment, transport, technical processes. The task of modeling the execution of schedules and network diagrams is relevant and useful. There are many counting systems, network graphs, however, the monitoring process based analysis of gaps and terms of graphs, no analysis of prediction execution schedule or schedules. The library is designed to build similar predictive models. Specifying source data to obtain a set of projections from which to choose one and take it for a new plan.

Information partnerships--shared data, shared scale.

How can one company gain access to another's resources or customers without merging ownership, management, or plotting a takeover? The answer is found in new information partnerships, enabling diverse companies to develop strategic coalitions through the sharing of data. The key to cooperation is a quantum improvement in the hardware and software supporting relational databases: new computer speeds, cheaper mass-storage devices, the proliferation of fiber-optic networks, and networking architectures. Information partnerships mean that companies can distribute the technological and financial exposure that comes with huge investments. For the customer's part, partnerships inevitably lead to greater simplification on the desktop and more common standards around which vendors have to compete. The most common types of partnership are: joint marketing partnerships, such as American Airline's award of frequent flyer miles to customers who use Citibank's credit card; intraindustry partnerships, such as the insurance value-added network service (which links insurance and casualty companies to independent agents); customer-supplier partnerships, such as Baxter Healthcare's electronic channel to hospitals for medical and other equipment; and IT vendor-driven partnerships, exemplified by ESAB (a European welding supplies and equipment company), whose expansion strategy was premised on a technology platform offered by an IT vendor. Partnerships that succeed have shared vision at the top, reciprocal skills in information technology, concrete plans for an early success, persistence in the development of usable information for all partners, coordination on business policy, and a new and imaginative business architecture.

Open Access to Research Articles and Data: Library Roles

Science.gov (United States)

Joseph, Heather

2015-08-01

Over the past decade, a handful of key developments have caused scholars and researchers to rethink not only the way they conduct their work, but also the way in which they communicate it to others. The advent of the Internet has provided unprecedented opportunities for immediate, cost effective global connectivity, opening up new possibilities for collaboration and communication. This has resulted in scholarship increasingly being conducted in the online environment, and a vast amount of new digital information being generated and made widely available to those interested in using it. Additionally, the Internet is a dynamic environment, with new channels for producing and sharing information in a myriad of formats emerging frequently.In higher education, the momentum of the burgeoning movement towards "open" sharing of information of all kinds continues to gain traction. In particular, advancements in the areas of opening up access to articles and reserch data are increasingly visible. In both of these areas, academic and research libraries are playing important, central roles in promoting the awareness of the potential costs and benefits of a more open research environment, as well as defining new roles for libraries in this digital environment.As this push for grater openness continues, these fronts are intersecting in interesting and potentially transformative ways. The Open Access and Open Data movements share fundamental philosophical commonalities that make collaboration a natural outcome. Both movements place a premium on reducing barriers to discovering and accessing pertinent digital information. Perhaps even more significantly, both explicitly recognize that enabling productive use of digital information is key to unlocking its full value. As a result of these shared priorities, there are a wide variety of common strategies that libraries can take to help advance research, presenting new opportunities for deeper collaboration to take place.This talk will

Tamper-proof secret image-sharing scheme for identifying cheated secret keys and shared images

Science.gov (United States)

Chen, Chien-Chang; Liu, Chong-An

2013-01-01

A (t,n) secret image-sharing scheme shares a secret image to n participants, and the t users recover the image. During the recovery procedure of a conventional secret image-sharing scheme, cheaters may use counterfeit secret keys or modified shared images to cheat other users' secret keys and shared images. A cheated secret key or shared image leads to an incorrect secret image. Unfortunately, the cheater cannot be identified. We present an exponent and modulus-based scheme to provide a tamper-proof secret image-sharing scheme for identifying cheaters on secret keys or shared images. The proposed scheme allows users to securely select their secret key. This assignment can be performed over networks. Modulus results of each shared image is calculated to recognize cheaters of a shared image. Experimental results indicate that the proposed scheme is excellent at identifying cheated secret keys and shared images.

One-way shared memory

Standard multicore processors use the shared main memory via the on-chip caches for communication between cores. However, this form of communication has two limitations: (1) it is hardly time-predictable and therefore not a good solution for real-time systems and (2) this single shared memory...... is a bottleneck in the system. This paper presents a communication architecture for time-predictable multicore systems where core-local memories are distributed on the chip. A network-on-chip constantly copies data from a sender core-local memory to a receiver core-local memory. As this copying is performed...... in one direction we call this architecture a one-way shared memory. With the use of time-division multiplexing for the memory accesses and the network-on-chip routers we achieve a time-predictable solution where the communication latency and bandwidth can be bounded. An example architecture for a 3...

In October 1998, the National Library of Medicine (NLM) launched a pilot project to learn about the role of public libraries in providing health information to the public and to generate information that would assist NLM and the National Network of Libraries of Medicine (NN/LM) in learning how best to work with public libraries in the future. Three regional medical libraries (RMLs), eight resource libraries, and forty-one public libraries or library systems from nine states and the District of Columbia were selected for participation. The pilot project included an evaluation component that was carried out in parallel with project implementation. The evaluation ran through September 1999. The results of the evaluation indicated that participating public librarians were enthusiastic about the training and information materials provided as part of the project and that many public libraries used the materials and conducted their own outreach to local communities and groups. Most libraries applied the modest funds to purchase additional Internet-accessible computers and/or upgrade their health-reference materials. However, few of the participating public libraries had health information centers (although health information was perceived as a top-ten or top-five topic of interest to patrons). Also, the project generated only minimal usage of NLM's consumer health database, known as MEDLINEplus, from the premises of the monitored libraries (patron usage from home or office locations was not tracked). The evaluation results suggested a balanced follow-up by NLM and the NN/LM, with a few carefully selected national activities, complemented by a package of targeted activities that, as of January 2000, are being planned, developed, or implemented. The results also highlighted the importance of building an evaluation component into projects like this one from the outset, to assure that objectives were met and that evaluative information was available on a timely basis, as was

Encyclopedia and library in the contemporary age

Full Text Available With the publication of the Encyclopédie of Diderot and D’Alembert, which dates from 1751, the concept of library is declined in a negative sense, as a closing tool and impediment in the hands of the State, compared to the Encyclopedia, considered the book of the people. The constitution of the public library (the british Public Libraries Act is dated 1850, funded with public money, determines to change and both realities, Library and Encyclopedia, begin to interact contributing to the development of contemporary culture. Such as the Library, the Encyclopedia also supposes a work of organization of knowledge through classifications. From this point of view, both institutions seem closer in a purpose that unites them. In view of the information revolution, the Library should help reduce complexity of digital information and should play, against the vastness of the network, a role similar to what the Enlightenment Encyclopedia has assigned to itself in the face of large library collections, which were seen as points of accumulation, and also as points of the knowledge’s dispersion.

Acceptance of shared decision making with reference to an electronic library of decision aids (arriba-lib) and its association to decision making in patients: an evaluation study.

Hirsch, Oliver; Keller, Heidemarie; Krones, Tanja; Donner-Banzhoff, Norbert

Decision aids based on the philosophy of shared decision making are designed to help patients make informed choices among diagnostic or treatment options by delivering evidence-based information on options and outcomes. A patient decision aid can be regarded as a complex intervention because it consists of several presumably relevant components. Decision aids have rarely been field tested to assess patients' and physicians' attitudes towards them. It is also unclear what effect decision aids have on the adherence to chosen options. The electronic library of decision aids (arriba-lib) to be used within the clinical encounter has a modular structure and contains evidence-based decision aids for the following topics: cardiovascular prevention, atrial fibrillation, coronary heart disease, oral antidiabetics, conventional and intensified insulin therapy, and unipolar depression. We conducted an evaluation study in which 29 primary care physicians included 192 patients. After the consultation, patients filled in questionnaires and were interviewed via telephone two months later. We used generalised estimation equations to measure associations within patient variables and traditional crosstab analyses. Patients were highly satisfied with arriba-lib and the process of shared decision making. Two-thirds of patients reached in the telephone interview wanted to be counselled again with arriba-lib. There was a high congruence between preferred and perceived decision making. Of those patients reached in the telephone interview, 80.7% said that they implemented the decision, independent of gender and education. Elderly patients were more likely to say that they implemented the decision. Shared decision making with our multi-modular electronic library of decision aids (arriba-lib) was accepted by a high number of patients. It has positive associations to general aspects of decision making in patients. It can be used for patient groups with a wide range of individual
