Innovation in language education: enriching Arabic language learner experiences and proficiency in 2D and 3D environments.

Abstract:-Global language and cultural communicative competency is an ever increasing requirement in our connected world. Learners of Arabic at the only five Australian universities where Arabic is taught have access to predominantly on-campus delivery modes. One of the main challenges learners face when learning another language (L2) in an academic setting in countries where that language is not actively used – so little L2 exposure – is that it is harder to provide meaningful contexts for learning. This restriction in L2 exposure in the formal academic framework is due to the limited face-to-face learning time and, more significantly, is compounded by lack of exposure to the language‟s authentic use settings. Students are often isolated from the target language‟s authentic discourse communities and native speakers. This situation is exacerbated for Cloud (online) students, studying in relative isolation. All of these factors make developing communicative oral fluency in Modern Standard Arabic (MSA) moredifficult and challenging for many learners. This paper will discuss two innovative approaches used at Deakin University in Melbourne, Australia to enable learners of Arabic at Deakin University to practice their developing skills by listening, practising, and experiencing directly how the language is used outside the classroom boundaries as well as allow learners to develop their oral and cultural communicative competency by engaging them in simulating and evolving authentic language scenarios with native Arabic speakers through the Virtual World (VW).

Regional variability in diving physiology and behavior in a widely distributed air-breathing marine predator, the South American sea lion Otaria byronia

Our understanding of how air-breathing marine predators cope with environmental variability is limited by our inadequate knowledge of their ecological and physiological parameters. Due to their wide distribution along both coasts of the sub-continent, South American sea lions (Otaria byronia) provide a valuable opportunity to study the behavioral and physiological plasticity of a marine predator in different environments. We measured the oxygen stores and diving behavior of South American sea lions throughout most of its range, allowing us to demonstrate that diving ability and behavior vary across its range. We found no significant differences in mass-specific blood volumes of sea lions among field sites and a negative relationship between mass-specific oxygen storage and size, which suggests that exposure to different habitats and geographical locations better explains oxygen storage capacities and diving capability in South American sea lions than body size alone. The largest animals in our study (individuals from Uruguay) were the most shallow and short duration divers, and had the lowest mass-specific total body oxygen stores, while the deepest and longest duration divers (individuals from Southern Chile) had significantly larger mass-specific oxygen stores, despite being much smaller animals.Our study suggests that the physiology of air-breathing diving predators is not fixed, but that it can be adjusted, to a certain extent, depending on the ecological setting and or habitat. These adjustments can be thought of as a "training effect" as the animal continues to push its physiological capacity through greater hypoxic exposure, its breath holding capacity increases.

El aprendizaje en una comunidad en internet de profesores de español como segunda lengua: estudio etnográfico virtual de la comunidad Todoele

In the digital era the availability of resources for online learning has multiplied along with personal learning environments. Proof of this is the proliferation of phenomena in the internet like Open Educational Resources or the Massive Open Online Course (MOOC) and the vast diversity of Online Communities of Practice (OCoP). The former is the object of study in the present Thesis. As Juan Freire (2012: 71) wrote: “The education is already happening, specially outside of educational institutions and formal process of education.” The OCoP garnered attention in the research community during the last few years. And, according to published research, online communities are turning into an emerging phenomena not only for “digital natives” (White, 2011) but also for lifelong learning (Wenger et al, 2002; Dubé et al, 2006; Lai et al, 2006) and specially as a tool for teacher training (Garrido, 2003; Murua, 2015). Teachers develop, through these tools, networks of self support, share didactic material, and look for solutions to common problems while undertaking initiatives towards even more collaboration. The present thesis is a study of Comunidad Todoele (CT) one of the most reputable networks for Spanish as a Foreign Language Teachers (ELE, from it’s Spanish acronym). Currently the community has near 11,000 members and it’s main purpose is researching, describing, and theorising the formative processes that happen inside the network from the perspective of those experiencing it. Debate is centred on the questions: What relevant knowledge do the teachers get from the community? In which way are these processes of learning developed? In other words, How, and what, do teachers learn in these environment?..

Trust, security and privacy in emerging distributed systems FGCS

The rapid development and increasing complexity of computer systems and communication networks coupled with the proliferation of services and applications in both Internet-based and ad-hoc based environments have brought network and system security issues to the fore. We have been witnessing ever-increasing cyber attacks on the network and system leading to tarnished confidence and trusts in the use of networked distributed systems. As a result, there is an increasing demand for development of new trust, security and privacy approaches to guarantee the privacy, integrity, and availability of resources in networked distributed systems.

Skill development for innovative procurement environments in construction

The construction industry should be a priority to all governments because it impacts economically and socially on all citizens. Sector turnover in industrialised economies typically averages 8-12% of GDP. Further, construction is critical to economic growth. Recent Australian studies estimate that a 10% gain in efficiency in construction translates to a 2.5% increase in GDP Inefficiencies in the Australian construction industry have been identified by a number of recent studies modelling the building process. They have identified potential savings in time of between 25% and 40% by reducing non-value added steps in the process. A culture of reform is now emerging in the industry – one in which alternate forms of project delivery are being trialed. Government and industry have identified Alliance Contracting as a means to increase efficiency in the construction industry as part of a new innovative procurement environment. Alliance contracting requires parties to form relationships and work cooperatively to provide a more complete service. This is a significant cultural change for the construction industry, with its well-known adversarial record in traditional contracting. Alliance contracts offer enormous potential benefits, but the Australian construction industry needs to develop new skills to effectively participate in the new relationship environment. This paper describes a collaborative project identifying skill needs for clients and construction professionals to more effectively participate in an increasingly sophisticated international procurement environment. The aim of identifying these skill needs is to assist industry, government, and skill developers to prepare the Australian construction workforce for the future. The collaborating Australian team has been fortunate to secure the Australian National Museum in Canberra as its live case study. The Acton Peninsula Development is the first major building development in the world awarded on the basis of a joint alliance contract.

Exploring the effectiveness of virtual product placement on recall and recognition of new brands

This paper investigates the effectiveness of virtual product placement as a marketing tool by examining the relationship between brand recall and recognition and virtual product placement. It also aims to address a gap in the existing academic literature by focusing on the impact of product placement on recall and recognition of new brands. The growing importance of product placement is discussed and a review of previous research on product placement and virtual product placement is provided. The research methodology used to study the recall and recognition effects of virtual product placement are described and key findings presented. Finally, implications are discussed and recommendations for future research provided.
