Data curation standards and the messy world of social science occupational information resources

Occupational information resources – data about the characteristics of different occupational positions – play a unique role in social science research. They are of relevance across diverse research disciplines and in numerous disparate contexts. They are also very widely available, typically freely downloadable from research-oriented academic web-pages. But they are also one of the most uncoordinated types of information resource that social scientists routinely come across. In this paper we describe issues in curating occupational information resources during the GEODE research project (Grid Enabled Occupational Data Environment, http:/www.geode.stir.ac.uk). This project attempts to develop long-term standards for the distribution of occupational information resources, by providing a standardised framework electronic depository for occupational information resources, and by providing a data-indexing service, premised upon eScience middleware, which collates occupational information resources and makes them readily accessible to non-specialist social scientists

Data curation standards and social science occupational information resources

Occupational information resources - data about the characteristics of different occupational positions - are widely used in the social sciences, across a range of disciplines and international contexts. They are available in many formats, most often constituting small electronic files that are made freely downloadable from academic web-pages. However there are several challenges associated with how occupational information resources are distributed to, and exploited by, social researchers. In this paper we describe features of occupational information resources, and indicate the role digital curation can play in exploiting them. We report upon the strategies used in the GEODE research project (Grid Enabled Occupational Data Environment, http://www.geode.stir.ac.uk). This project attempts to develop long-term standards for the distribution of occupational information resources, by providing a standardized framework-based electronic depository for occupational information resources, and by providing a data indexing service, based on e-Science middleware, which collates occupational information resources and makes them readily accessible to non-specialist social scientists

Beyond ‘greeting’ and ‘thanking’: politeness in job interviews

Despite the steps taken by Malaysian institutions of higher learning to equip their graduates with the necessary communication skills, local graduates are still failing to create a positive impression on the employers especially during job interviews. Hence this study explored the face-related concept of politeness proposed by Brown and Levinson (1999) at job interviews. Eight final-year undergraduates taking a communication for employment course volunteered for a mock-interview session with a human resource manager from the banking industry. The interviews were audio- and video-recorded and subsequently transcribed. Then a micro-analysis of the data was carried out using Brown and Levinson’s (1999) framework to identify the politeness strategies that the candidates used. Two positive politeness strategies were identified, the first is noticing and attending to interviewer’s interests, wants, needs or goods, and second is raising/asserting common grounds to establish solidarity. One negative politeness strategy was identified which is requesting for clarification or repetition. The pedagogical implications of these findings will be discussed and recommendations for teaching face-related politeness in communication for employment courses will be offered

Digital Heritage Gamification: An Augmented-Virtual Walkthrough to Learn and Explore Tangible Cultural Heritage

In the last decade, cultural heritage including historical sites are reconstructed into digital heritage. Based on UNESCO , digital heritage defines as “cultural, educational, scientific and administrative resources, as well as technical, legal, medical and other kinds of information created digitally, or converted into digital form from existing analogue resources”. In addition, the digital heritage is doubling in size every two years and expected will grow tenfold between 2013 and 2020. In order to attract and stir the interest of younger generations about digital heritage, gamification has been widely promoted. In this research, a virtual walkthrough combine with gamifications are proposed for learning and exploring historical places in Malaysia by using mobile device. In conjunction with Visit Perak 2017 Campaign, this virtual walkthrough is proposed for Kellie’s Castle at Perak. The objectives of this research are two folds 1) modelling and design of innovative mobile game for virtual walkthrough application, and 2) to attract tourist to explore and learn historical places by using sophisticated graphics from Augmented Reality. The efficiency and effectiveness of the mobile virtual walkthrough will be accessed by the International and local tourists. In conclusion, this research is speculated to be pervasively improve the cultural and historical knowledge of the learners

Improvement of dielectric loss of doped Ba0.5Sr0.5TiO3 thin films for tunable microwave devices

Al2O3-Ba0.5Sr0.5TiO3 (Al2O3-BST) thin films, with different Al2O3 contents, were deposited on (100) LaAlO3 substrate by pulsed laser deposition (PLD) technique. The Al2O3-BST films was demosnstrated to be a suitable systems to fabricate ferroelectric thin films with low dielectric loss and higher figure of merit for tunable microwave devices. Pure BST thin films were also fabricated for comparison purpose. The films' structure and morphology were analyzed by X-ray diffractiopn and scanning electron microscopy, respectively; nad showed that the surface roughness for the Al2O3-BST films increased with the Al2O3 content. Apart from that, the broadening in the intensity peak in XRD result indicating the grain size of the Al2O3-BST films reduced with the increasing of Al2O3 dopant. We measured the dielctric properties of Al2O3-BST films with a home-made non-destructive dual resonator method at frequency ~ 7.7 GHZ. The effect of doped Al2O3 into BST thin films significantly reduced the dielectric constant, dielectric loss and tunability compare to pure BST thin film. Our result shows the figure of merit (K), used to compare the films with varied dielectric properties, increased with the Al2O3 content. Therefore Al2O3-BST films show the potential to be exploited in tunable microwave devices.Comment: 8 pages, 4 figures, 1 table.

Effects of nano-SiC addition on the superconducting properties of magnesium diboride

In this study, we report the results on phase formation, microstructures, and superconducting properties of a series of MgB2 samples with different level of SiC additions. The polycrystalline samples were prepared via solid state reaction by mixing magnesium, boron and silicone carbide powders according to the ratio of Mg:B:SiC = 1:2:x. XRD spectra showed that MgB2 is the primary phase while Mg2Si, MgO and MgB4, together with some unreacted SiC are the secondary phases as the addition increases. The presence of Mg2Si became more significant as the addition level increased. SEM images showed smaller grains as the addition level increases indicating more grain boundaries were formed. The Tc was as low as 30.5K for x=15wt%. The field dependence of Jc showed that x=1wt% sample gave the best performance at both 5K and 20K
