Public geological achievement platform is a part of science and technology infrastructure and related to sustainable development of the economy and society. By literature research, expert's discussion and case study, the paper proposes that centralized sharing with local sharing mechanism and multi-layers network have to be set up to achieve public geological achievements sharing. The operating...

In the context of Computer-Supported Collaborative Learning (CSCL), Web 2.0 applications are increasingly being used for Technology-Enhanced Learning (TEL). The paper presents the main principles of Web 2.0 and develops the hypotheses derived from the central aspect of collaborative learning. These hypotheses refer to the significance of Web 2.0 for the technical support of various collaborativ...

Healthcare systems around the globe are facing a number of challenges. Thus Increasing focus is being placed on constructing appropriate healthcare reforms which are attempting to address how to tackle these challenges. A critical enabler in these reforms is the adoption of an e-health solution. Such e-health solutions are not only expensive and complex endeavours, but also have far reaching im...

Several operating systems projects revolve around moving functionality above or below the kernel “red line” to increase flexibility or performance. We describe how a general model of partial evaluation encompasses this trend. The operating systems community should not be content with a single interface between applications and the operating system, even if that interface allows extension below ...

In this paper, a new method is proposed for estimating the depreciation rate of technological knowledge based on the analysis of technology cycle time (TCT). Patent citation data are used in an empirical analysis. The following features characterize the proposed TCT-based method: i) Estimation of the depreciation rate is measured by using the entire set of patents; and ii) The current approach ...

The Australian National Corpus has been established in an effort to make currently scattered and relatively inaccessible data available to researchers through an online portal. In contrast to other national corpora, it is conceptualised as a linked collection of many existing and future language resources representing language use in Australia, unified through common technical standards. This a...

The integration of modern Information and Communication Technologies (ICTs) within the cultural domain creates what is commonly known as e-culture. The need to create an e-culture environment arose from the undeniable fact that the cultural heritage of a nation defines a nation and therefore should be disseminated to all, regardless of their location and their disability. This article discusses...

Matt Spiegel for their comments and suggestions. Abstract This paper develops a model of optimal capital structure with stochastic interest rate which is assumed to follow a mean-reverting process. Closed-form solutions are obtained for both the value of the firm and the value of its risky debt. The paper finds that the current level and the long-run mean of the interest rate process play disti...
