    Using Linked Data as a basis for a Learning Resource Recommendation System

    No full text
    Resource List Management Systems (RLMS) allow the electronic publication of course reading lists. Aside from electronic access, existing systems in this area provide little utility for teachers and learners above and beyond the traditional paper based reading lists. Our vision is that resource lists could in actual fact become Open Educational Resources that can be shared, re-mixed and re-used across institutions and borders. This paper introduces how we used linked data to architect a RLMS to meet this vision. However, in implementing this system, questions arose around the provenance, sustainability, licensing and reliability of today's linked data cloud. This paper documents the steps we took to address these criticisms in our implementation. The paper goes on to discuss how the ecosystem of learning data managed by this application opens the way for future work, which involves leveraging typed relationships between learning goals, educational resources and system actors to provide recommendation-like services for academics creating new content

    If You Can Measure It, You Can Manage It: A Case of Intellectual Capital

    No full text
    Despite the great importance attributed to intellectual capital (IC) in the past two decades or so, its measurement and management have remained elusive, mainly because of inappropriate prior models of IC measurement. The purpose of this study is, therefore, to make adjustments to an existing model, the Value Added Intellectual Coefficient (VAIC), and to present an adjusted-VAIC model to measure IC. We tested our new model on data from 10 emerging and developed world markets and obtained more consistent results than prior studies. Our results indicate a significant positive relationship between IC and its components (human, innovation and physical capitals) and firm performance. Therefore, the adjusted-VAIC model can be used with confidence to measure IC.Our study has important implications for both academia and industry concerning the measurement of IC

    Let R\mathscr{R} be a prime ring of Char(R)2(\mathscr{R}) \neq 2 and m1m\neq 1be a positive integer. If SS is a nonzero skew derivation with an associatedautomorphism T\mathscr{T} of R\mathscr{R} such that ([S([a,b]),[a,b]])m=[S([a,b]),[a,b]]([S([a, b]), [a,b]])^{m} = [S([a, b]), [a, b]] for all a,bRa, b \in \mathscr{R}, thenR\mathscr{R} is commutative

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    What macroeconomic policies are"sound?"

    No full text
    Most people agree that the soundness of macroeconomic policies should be judged by their efficacy in meeting the objectives of steady growth, full employment, stable prices, and a viable external payments situation. What people debate about are the links between macroeconomics and economic structure--and in the current environment, the openness to foreign capital flows. As developing countries become more integrated into international financial markets, volatility may become an increasing fact of life. Faced with such volatility, how should these countries frame their macroeconomic policies? What broad principles should guide their macroeconomic management? In many developing countries, the openness of the capital account has been significant. Many countries have made the transition toward an open-economic paradigm. As a result, fluctuations in international capital and currency markets, as well as shifts in foreign investors'attitudes and confidence, have greatly affected local stock market prices, the level of foreign exchange reserves, and the scope for monetary and interest rate policy. Capital controls and foreign exchange restrictions have been significantly dismantled in a number of developing and transition economies. In 1970, only 34 countries--or 30 percent of the International Monetary Fund's membership-had assumed Article VIII of the IMF Articles of Agreement, declaring their currency convertible on current account transactions. By 1997, this figure had increased to 77 percent. Does financial integration make it more difficult to achieve macroeconomic stability? Apparently not, on the whole, although at times large short-term capital flows can lead to misaligned asset prices, including exchange rates. What financial integration does do is limit how far countries can pursue policies incompatible with medium-term financial stability. The disciplining effect of global financial and product markets applies not only to policymakers-through pressures on financial markets-but also to the private sector. Rather than constrain the pursuit of appropriate policies, globalization may add leverage and flexibility to such policies, easing financing constraints and extending the time during which countries can make adjustments. But markets will provide this leeway only if they perceive that countries are undertaking adjustments that address fundamental choices.Economic Theory&Research,Fiscal&Monetary Policy,Payment Systems&Infrastructure,Banks&Banking Reform,Environmental Economics&Policies,Banks&Banking Reform,Environmental Economics&Policies,Financial Intermediation,Economic Theory&Research,Macroeconomic Management
