    Please note: this article is in Greek. E-Learning of Modern Greek in South Australian schools: This paper attempts to look into the usage of new technologies in teaching Modern Greek in five South Australian Schools, four of them public and one independent. A questionnaire was given to one hundred students with the objective of collecting and analyzing the results. Based on the data collected, a number of conclusions were drawn regarding whether new technologies are actually used, to what extent, and what should be done to utilize them with the best outcome in the future

    E-Procurement Framework for Shipping

    The existing procurement process in shipping is paper-based and labor-intensive. Looking to cut costs and improve delivery times, while simultaneously enabling companies to take a more strategic approach to their jobs, an eprocurement framework is proposed to automate and streamline its procurement process by bringing it online. In this paper we present an intranet Web-based electronic procurement infrastructure. The shipping organizational process requirements was fully analyzed and evaluated. The ships as end-users were provided with access to the application taking into account the existing communication cost and restrictions. The logical Architecture is presented including the schema of the databases, the catalog management, the workflow of the purchase order plus the end-users interaction with the procurement system through Web browser. Then the physical architecture is described when security, load simulation and several well known technologies are applied. In all step the shipping environment and its specific characteristics are fully assessed. The application in its pilot implementation (marine engines spare parts procurement) shows that is scaleable, has a supplier integration strategy that met the shipping company’s core requirement, is relatively eas y to install, configure and use and can be integrated with ERP

    Planning for authentic language assessment in higher education synchronous online environments

    The teaching of some languages in Australia is under threat due substantially to small enrolments. There is considerable need to preserve Australia’s community languages as part of the country’s cultural and linguistic diversity. However, it can be difficult to generate sufficient numbers to sustain the provision of a specific language course in any one location in Australia. Online technologies can provide a solution to this problem. According to the New Media Consortium Horizon Report: 2012 Higher Education Edition “education paradigms are shifting to include online learning, hybrid learning and collaborative models”. Models such as these present a possible solution to the problems associated with providing small enrolment language topics such as Modern Greek. The Logos Australian Centre for Hellenic Language and Culture was established at Flinders University in 2011. Promotion and preservation of Greek language and culture is the focus of the centre which is funded by the South Australian Government with support from the Greek Government. In 2012 the centre moved towards enhancing the delivery of Modern Greek by developing and delivering four language topics and two culture topics online. The delivery of these topics identified assessment as an area which needs further investigation. This paper describes the importance of an assessment strategy for foreign language (FL) learning which is based on the principles of authentic assessment and describes how synchronous technologies can support this strategy

    Modern Greek at tertiary level: applying innovative methods of effective assessment and delivery online

    In a determined effort to preserve the Modern Greek language as an important part of Australia’s cultural and linguistic diversity, the Logos Australian Centre for Hellenic Language and Culture established at Flinders University in South Australia in 2011 has been enhancing the delivery of Modern Greek and enabling a wider delivery of this small enrolment language by developing online content and an effective model for delivery via synchronous and asynchronous technologies. Six Modern Greek language topics, two cultural topics and some extension materials have been developed and delivered online via the university’s learning management system known as Flinders Learning Online (FLO)

    Α GARCH examination of macroeconomic effects on U.S. stock market : a distinction between the total market index and the sustainability index

    Get PDF
    The paper examines the impact of several macroeconomic variables on the Dow Jones Sustainability and Dow Jones Wilshire 5000 indexes, using a GARCH model and monthly data for the period January, 2000 to January, 2008. The results show that changes in returns of crude oil prices affect negatively the U.S. stock market, contrary to changes in returns of the 10-year bond value that affect it positively. Both economic indicators influence the DJSI with a month delay. Also, the exchange rate volatility affects negatively the returns of the U.S. stock market and the non-farm payroll can be characterised as a stabilising factor for the DJSI.peer-reviewe

    On the mechanism of the Au(I)‐mediated addition of alkynes to anthranils to furnish 7‐acylindoles

    Get PDF
    Indole is a very common structural motif in alkaloids with a remarkable history in pharma industry. In the continuous search for more direct and efficient access to these valuable structures, a new and rather elegant approach was found by Jin and coworkers, which involved a gold(I)-mediated addition of alkynes onto anthralins. This approach selectively furnishes 7-acylindoles in a rather expeditious way, and it has been shown to be compatible with a large range of decorated reactants, both at the alkyne side and at the anthralin side. We studied the mechanism of this reaction with a set of different alkynes, including disubstituted ones, to establish similarities and differences between them and to aid in the elucidation of key steps in the reaction pathway. The observed regioselectivity seems to be connected to the irreversible formation of a key α-imino gold carbene intermediate, common to all reaction profiles, through the initial regioselective nucleophilic attack of the anthranil N atom onto the alkyne fragment.Xunta de Galicia | Ref.

    Accepting the blogging challenge: Modern Greek Language Teaching at Tertiary Level

    Get PDF
    Since the early 2000s, the educational merit of Web 2.0 authoring in the format of blogging has been widely promoted. In the higher education context, blogs have been used successfully for a wide range of purposes including to develop learner autonomy and intercultural competence (Lee, 2011); to increase student motivation to learn from peers via online interaction in the form of blog comments (Yang Chang, 2012); to support students during internships and placements (Chu, Chan Tiwari, 2012); ‘to develop literary, communicative and digital skills’ (Neira-Piñeiro, 2015: 555); to create an inclusive, communicative learning environment (Kim, 2012); to achieve reflective learning (Muncy, 2014) and as part of an assessment process in which student blogs were tracked ‘with the aim of improving self-reflective processes and providing feedback’(Ion, Cano Ferrer, 2014: 238)

    Cycloaddition Strategies for the Synthesis of Diverse Heterocyclic Spirocycles for Fragment-Based Drug Discovery.

    Get PDF
    In recent years the pharmaceutical industry has benefited from the advances made in fragment-based drug discovery (FBDD) with more than 30 fragment-derived drugs currently marketed or progressing through clinical trials. The success of fragment-based drug discovery is entirely dependent upon the composition of the fragment screening libraries used. Heterocycles are prevalent within marketed drugs due to the role they play in providing binding interactions; consequently, heterocyclic fragments are important components of FBDD libraries. Current screening libraries are dominated by flat, sp2-rich compounds, primarily owing to their synthetic tractability, despite the superior physicochemical properties displayed by more three-dimensional scaffolds. Herein, we report step-efficient routes to a number of biologically relevant, fragment-like heterocyclic spirocycles. The use of both electron-deficient and electron-rich 2-atom donors was explored in complexity-generating [3+2]-cycloadditions to furnish products in 3 steps from commercially available starting materials. The resulting compounds were primed for further fragment elaboration through the inclusion of synthetic handles from the outset of the syntheses
