    No full text
    This paper reports a bibliometric study of the development of computer science research in the People's Republic of China in the 21st century, using data from the Web of Science, Journal Citation Reports and CORE databases. Focusing on the areas of data mining, operating systems and web design, it is shown that whilst the productivity of Chinese research has risen dramatically over the period under review, its impact is still low when compared with established scientific nations such as the USA, the UK and Japan. The publication and citation data for China are compared with corresponding data for the other three BRIC nations (Brazil, Russian and India). It is shown that China dominates the BRIC nations in terms of both publications and citations, but that Indian publications often have a greater individual impact. Š The Author(s) 2012

    Comparative Advantage Learning Software: Application (Off-line) Software with Assessment Capabilities

    Get PDF
    This paper describes software, written by the author, for learning comparative advantage and the specialisation gains from trade. Starting with given absolute costs and available resources for two nations, the student constructs production possibilities curves. He or she then picks a term of trade and feasible levels of exports and imports at which both nations can gain from trade. This non-commercial software is application software rather than a web application. As such, it is easier to develop than comparable web applications. Traditionally, application software has lacked the relatively secure assessment (i.e. grading) capability of web applications. The software described in this paper, however, produces a verifiable assessment by producing a code based on the student's identifiers and his or her score. This code is then passed to the instructor who, using other software, decodes it.

    Legal Deposit Web Archives and the Digital Humanities: a Universe of Lost Opportunity?

    Get PDF
    Legal deposit libraries have archived the web for over a decade. Several nations, supported by legal deposit regu-lations, have introduced comprehensive national domain web crawling, an essential part of the national library re-mit to collect, preserve and make accessible a nation’s intellectual and cultural heritage (Brazier, 2016). Scholars have traditionally been the chief beneficiaries of legal de-posit collections: in the case of web archives, the poten-tial for research extends to contemporary materials, and to Digital Humanities text and data mining approaches. To date, however, little work has evaluated whether legal deposit regulations support computational approaches to research using national web archive data (Brügger, 2012; Hockx-Yu, 2014; Black, 2016). This paper examines the impact of electronic legal deposit (ELD) in the United Kingdom, particularly how the 2013 regulations influence innovative scholarship using the Legal Deposit UK Web Archive. As the first major case study to analyse the implementation of ELD, it will ad-dress the following key research questions:• • Is legal deposit, a concept defined and refined for print materials, the most suitable vehicle for suppor-ting DH research using web archives? • How does the current framing of ELD affect digital in-novation in the UK library sector? • How does the current information ecology, including not for-profit archives, influence the relationship between DH researchers and legal deposit libraries

    OneGeology : improving access to geoscience globally

    Get PDF
    Contributing scientific solutions to the challenges of landslides and earthquakes, minerals and mining, water supply and flooding, pollution and erosion, and — not least — climate change and energy supply, depends absolutely on geological data. Like most things environmental, few of these challenges respect national or scientific domain frontiers and if we want to assess and address these environmental challenges holistically then we need access to holistic data too. Rich environmental data does exist in each nation, but when it is available, and in many instances it is exceptionally difficult to discover, then it exists in different formats and via different services, with different access conditions. OneGeology is a global initiative to improve the accessibility of one fundamental environmental dataset — geological map data. In addition it is improving the interoperability of those data and the exchange of knowhow and experience. OneGeology has been hugely successful and today 116 nations are participating, with 50 of those nations serving geological data to a dynamic web map portal

    Web Based Services Provided by University Libraries of BRICS Nations: A Comparative Study

    Get PDF
    The developments in information and communication technologies (ICT) and their subsequent absorption in library and information science (LIS) have forced information professionals to change the way they are functioning at present. Because of their popularity with the users, an overwhelming attention is being given to the web-based information services in libraries .The web 2.0 technologies have rapidly gained huge popularity and as such, the university libraries, being the heart of the highest seats of learning, need to equip themselves with all the possible web based, i.e. web 2.0 and allied services. The present study made an endeavour to study the various web 2.0 and allied web based services offered by select university libraries of BRICS nations. This study shows that the web based services in the university libraries of BRICS nations are quite better. The findings show that India and china universities are far behind as compared to Brazil, Russia and South Africa in employability of web 2.0 tools in librarie

    Journal portfolio analysis for countries, cities, and organizations: maps and comparisons

    Get PDF
    Using Web of Science data, portfolio analysis in terms of journal coverage can be projected onto a base map for units of analysis such as countries, cities, universities, and firms. The units of analysis under study can be compared statistically across the 10,000+ journals. The interdisciplinarity of the portfolios is measured using Rao-Stirling diversity or Zhang et al.'s improved measure 2D3. At the country level we find regional differentiation (e.g., Latin American or Asian countries), but also a major divide between advanced and less-developed countries. Israel and Israeli cities outperform other nations and cities in terms of diversity. Universities appear to be specifically related to firms when a number of these units are exploratively compared. The instrument is relatively simple and straightforward, and one can generalize the application to any document set retrieved from the Web of Science (WoS).

    ConfBits: A Web Based Conference Management System

    Get PDF
    ConfBits is a Web-based Conference Management System (CMS) developed to aid effective organization and management of professional, academic and technical conferences. The web based application is an object-oriented and multi-conferences platform that is made up of four major actors which are authors, reviewers, administrators (otherwise known as Program Committee (PC) chair) and participants. Conference organizers in any Anglophone country can subscribe to the platform via the Internet to access and utilize the different features which include; abstract and full paper submissions, assignment of papers to reviewers, sending email notifications to authors and reviewers, participants management and conference program scheduling. The prototype of the platform is already deployed on the Internet and the trial Universal Resource Locator (URL) is www.cucms.com.ng. From our review of existing online CMSs, ConfBits (although still at a prototype stage) is the first of such system from a developing clime. We hope the platform will serve to bridge the hitherto wide digital divide between the developed and developing nations especially with respect to scholarly online content

    SEEA Revision: Accounting for Sustainability?

    Get PDF
    The 1993 United Nations System for integrated Environmental and Economic Accounting (SEEA) aimed at measuring the - environmental - sustainability of economic performance and growth in terms of produced and natural capital maintenance. To this end it advanced "greened" economic indicators, notably Environmentally-adjusted net Domestic Product (EDP) and Capital Formation (ECF). A revised (draft) version of the 1993 handbook, entitled "Integrated Environmental and Economic Accounting 2003" (IEEA), is now available on the web site of the United Nations Statistics Division. Despite its extensive discussion of sustainable development, the IEEA 2003 fails in measuring overall sustainability as it shuns monetary valuation of environmental impacts in a modular framework for physical, hybrid and - selective - monetary accounts. The revision thus missed an opportunity to bridge the persisting dichotomy between ecological and economic sustainability analysis. Future work should explore and test the capability of material flow and environmentally adjusted economic indicators to capture the elusive notions of strong and weak sustainability of economic activity.environmental accounting, sustainability, capital maintenance, dematerialization, green GDP, valuation

    Paranoid operative system methodology for anonymous & secure web browsing, doctoral project

    Get PDF
    Recently the world knew by the media, that its leading nations follow closely their citizens, disregarding any moral and technological threshold, that internal and external security agencies in the USA and Europe closely follow telephone conversations, e-mail, web traffic of their counterparts, using powerful monitoring and surveillance programs. In other corners of the globe nations in turmoil or wrapped in the cloak of censorship persecute and deny uncontrolled web access without harmful repercussions to their citizens. This work is a research-in-progress project and consists in showing the research done so far to develop a methodology. This consists in the construction of an operative system with an academic scientific source that permits a secure and anonymous use of the web. For such methodology, first is required to comprehend and get acquaintance with the technologies that controls usage of web consumers, solutions that enable and grant some anonymity and security in web traffic

    The not so smart, smart grid - potential security risks associated with the deployment of smart grid technologies

    Get PDF
    The electricity grid has been up until now a relatively stable artifice of modern industrialized nations. The power grids are the most widespread wired networks in the world. They are heavily regulated and standardized to protect the integrity, stability and reliability of supply. The grids have been essentially closed systems, this is now rapidly changing with the introduction of the network enabled smart meter. These meters are “web” accessible, connect and interact directly with electrical appliances in domiciles and businesses. This move now brings a range of extreme risks and complexities into these stable networks. This paper explores the security issues and potential problems associated with current moves to provide these smart meters to existing grid connections
