Checked baggage: spatial negotiations in contemporary air travel

This paper examines the act of undertaking international air travel and analyses how it forces individuals to consider a range of ideas as a result of dislocation and attempts to re-align themselves within spatial, material and biological structures. In order to balance the shifts between spatial and material experiences, travellers employ imaginative and perceptive procedures, gaining knowledge through experience. At the intersection of participatory and spatial boundaries through the lens of multi-disciplinary literature, this paper explores how practices of individuals within international air travel provides alternative modes of thinking and navigating through personal, cultural and globalised public spaces.

Time series analysis of air transportation service quality and travel demand in Japan

The evolution of domestic air travel service in Japan is a product of many factors including airline responses to the changing aviation market, government interventions in terms of regulatory/deregulatory policies, infrastructure investments, and changes in market structure. This paper presents an empirical investigation of the changing quality of passenger airline service and its implications in the domestic aviation market in Japan using qualitative review and a time series analysis of the domestic airline markets from 1986 to 2003. The results show that to meet the ultimate aim of deregulation to increase air passengers’ welfare gain, there is a need to instill measures to correct service imbalance and to create innovative airport demand-capacity management measures.

Uncertainty and reluctance in teaching taboo language: a case study of an experienced teacher of English as an additional language

Despite its ubiquitous employment by users of English to achieve authentic communicative goals, taboo language has received little attention in the education literature. Even less focus has been placed on such language in English language teaching - specifically, in teaching English as an Additional Language (EAL). Given the multiplicity of communicative struggles experienced by EAL learners surrounding the use of taboo language in authentic communication, meaningful consideration of this aspect can be seen as crucial in EAL instruction. Classroom learning could prepare learners for navigation and negotiation of taboo language use they will inevitably encounter in social interactions in target language communities of practice. However, EAL teachers' uncertainty or reluctance to introduce taboo language in classroom instruction is a key impediment in developing learners' sociocultural knowledge regarding such language use. We foreground one case of such uncertainty and reluctance surrounding the introduction of taboo language in EAL instruction derived as interview data from an experienced EAL teacher.

Request mitigating devices in Australian English and Iraqi Arabic : a comparative study

Speech acts realization in everyday interaction is seen as an important field to explore the impact of linguistic and cultural variations on cross-cultural communication and second language acquisition. The reported study investigates the use of request mitigating devices in Australian English and Iraqi Arabic. It explores the internal and external devices that speakers of the two languages use to mitigate the imposition force of requests and the impact of the linguistic and cultural parameters on this use. Request samples were collected from 14 native speakers of Australian English and 14 native speakers of Iraqi Arabic by means of eight role-play interviews. The mitigating devices were identified and classified according to a modified categorization scheme based on Blum-Kulka et al. (1989). Additional categories of mitigating devices were added to this scheme to meet the requirements of data analysis. These include consultative device (Blum-Kulka & Olshtain, 1984), questions (Trosborg, 1995), apology (Economidou-Kogetsidis, 2008), alerter (Schauer, 2007), closing (Al-Ali & Alawneh, 2010), and new categories: wish/hope statement and verbal incentive. The results showed that internal mitigating devices were more frequent in Australian English requests than in Iraqi Arabic requests, while external mitigating devices were equally pervasive in both groups. The two groups also used different semantic formulae of some mitigating devices in specific situations. The pervasive occurrence of external mitigators in both groups‟ requests is discussed in terms of volubility as a politeness strategy. It is suggested that the divergence between the two groups in their utilization of request mitigations is related to linguistic and cultural variations between the Australian and Iraqi languages and cultures.

Global English corner : using Elluminate to enhance international students' English language skills

Students at Victoria University (VU) in Melbourne, Australia, undertake their study in an English language context and they have a range of support options to assist with English language development. VU has partner universities in China (Sichuan University, Henan University and Liaoning University). VU’s programs in China often have fewer language support options than programs in Melbourne. The Australian Government’s Transnational Quality Strategy requires that educational programs on- and offshore provide students with a comparable learning experience. Given the relative lack of English speaking opportunities available to VU’s students in China, the university is exploring how technologies might achieve a greater comparability of the student experience. This paper reports on a pilot program that uses Elluminate to conduct English conversations between students in China and Australia. The perceived lack of English competence of international students has been an ongoing issue in Australian higher education while the ‘English corner’ is ‘a characteristically Chinese approach to informal practice’ (Jin & Cortazzi, 2002) that helps students learning English in a foreign context to develop their English language proficiency. How might the idea of ‘English corner’ be used with educational technologies to encourage international students to practise and develop their English? This paper discusses a pilot program at VU that combines the idea of the English Corner together with the online conferencing tool Elluminate and a blog developed in WordPress, to engage Chinese students offshore in English language conversations. Through Elluminate and the Global English Corner blog, a pair of student peers in Melbourne conducts semi-structured conversations with groups of students offshore. In Elluminate, students can both hear and see each other – and they can simultaneously txt chat, share documents, images and websites and use the collaborative whiteboard function of Elluminate – to have dynamic conversations in real time. Preliminary findings of this pilot that uses technology to emphasise the societal aspects of learning – including language learning – will be presented. The discussion will consider how a more widespread English Corner program could aid the transition of international students in Australia, encourage the interaction of local students and international students, increase opportunities for international students to practise English and achieve a greater comparability of language support options on- and offshore.

The impact of communications and understanding on the success of business/IT alignment

This article reports on an investigation of IS stakeholders communication and mutual understanding, and their impact on the success of business / IT alignment. In particular, by following a hermeneutic study of transcripts of two focus groups and several interviews conducted with senior business and IT executives, the paper explores the issues of modern business context and practices, project scope and structure, trust, language and nomenclature, and the barriers to the effective stakeholder communication and  understanding. The study results are finally compared against the standard model of business and IT alignment. The main unexpected finding being executives' pre-occupation with issues of "marginal" value to the alignment model, such as day-to-day management of communicative and understanding effectiveness, as opposed to the fundamental issues of strategy and infrastructure fit.

The development of knowledge about language in teacher training: what works?

Efforts have been made over many years by applied linguists in a number of English-speaking countries to raise awareness of language across the primary and secondary school curriculum, with varying degrees of success (see Denham & Lobeck, 2010). Many of these countries are sites of mass migration from non-English speaking countries, creating linguistic equity issues. In Australia, the new National Curriculum mandates that teachers of all disciplines will be required to provide pedagogy responsive to the language learning needs of English as an Additional Language (EAL) students. However, policy documents do not specify how this goal should be realized, and teachers and researchers are engaged in constant debate about what views of language could inform teacher training (e.g. structural and/or functional). This paper reports on a project which aimed to identify 1) the views of teacher educators on language in the curriculum, and 2) the language-related challenges faced by teachers in training. The current paper focuses on the language awareness of trainee teachers. Ten education students were interviewed about their understandings and experiences of language and language learning. It was found that many students experienced lack of confidence and knowledge about language (KAL), but that awareness of sociocultural elements of language provided them with ways to connect with a broader understanding of language issues. Results were analyzed from the perspective of sociocultural theory and will have implications for teacher training in any educational context where students are learning an additional language in order to integrate into a national schooling system.

N-doped pierced graphene microparticles as a highly active electrocatalyst for li-air batteries

In this work we report a novel scalable strategy to prepare a lithium-air battery electrode from 3D Ndoped pierced graphene microparticles (N-PGM) with highly active performance. This approach has combined the merits of spray drying technology and the hard template method. The pierced structured graphene microparticles were characterized physically and electrochemically. An x-ray
photoelectron spectrometer and Raman spectra have revealed that the novel structure possesses a higher N-doping level than conventional graphene without the pierced structure. A much higher BET surface area was also achieved for the N-PGMthan the conventional N-doped graphene microparticles (N-GM). Cyclic voltammetry indicated that the lithium-air battery with the N-PGM electrode has a better utilization for the graphene mass and a higher void volume for Li2O2 formation than that of theN-GMelectrode. N-PGMalso exhibits improved decomposition kinetics for Li oxide
species yielded in the cathodic reaction. Charge and discharge measurements showed that theN-PGM lithium-air battery achieved an improved specific capacity and an enhanced cycle performance than when anN-GMelectrode is used.

Extended-duration services evaluation: an exploratory study

There is a lack of research and literature concerned with services which are produced and delivered over substantial, sustained time periods. The growing Leisure Air Travel industry has a major component of extended–duration product (long-haul flights). In the existing literature, there is little or no distinction made between leisure and business travellers regarding their motivation and expectations, the duration of the service encounters and the travellers’ evaluation of the service. The authors propose that leisure and business travellers have distinct and differing motives for travelling which affect their service evaluation. The individual consumers’ characteristics, combined with industry conditions and the complex product component, mean that measuring consumer satisfaction, with leisure air travel, in a useful way is problematic. The authors suggest that a major part of the complexity of the product is that leisure air travel is a high-involvement, high-affect, extended service. In June 2000 and February 2001, exploratory research in the form of focus groups conducted using a total of 110 passengers from a United Kingdom leisure airline, revealed several important criteria used by consumers when evaluating service provision. The criteria are grouped into six factors: Hygiene, Service/Empathy, Psychological, Temporal, Personal Characteristics, and Situation Specifics. A new model for examining the relationships between the factors, the
airline and satisfaction evaluation is proposed.

Actor network theory goes to school

Actor Network Theory (ANT) is explored as a useful tool in researching the intersection of English teaching and Information Communication Technologies (ICTs), to understand the complex interaction of influences, both human and non-human, that combine to achieve a particular outcome, in this case the uptake of ICTs by English teachers in an Australian school. What this means is that alongside interviewing the teachers, administrators and technical support people, recognition is given to the influence of inanimate objects such as computers, bluestone walls and curriculum documents. This constructs a more complex picture of the change process accounting both for the invisible ideology of teacher beliefs as well as the technical capacity and incapacity of machines, buildings and policies. At the heart of ANT lies the metaphor of the heterogeneous network which is made up of diverse, not simply human, materials. Often these networks become consolidated as single point actors e.g. the English curriculum, the computer laboratory, the library, which are then seen as fixed entities rather than an amalgamation of parts prone to change. ANT allows for the constituent parts to be investigated, and following Bruno Latour's Aramis, (1996) this can be done creatively by literally giving voice to inanimate objects such as computers.

Mind change efficient learning

This paper studies efficient learning with respect to mind changes. Our starting point is the idea that a learner that is efficient with respect to mind changes minimizes mind changes not only globally in the entire learning problem, but also locally in subproblems after receiving some evidence. Formalizing this idea leads to the notion of uniform mind change optimality. We characterize the structure of language classes that can be identified with at most α mind changes by some learner (not necessarily effective): A language class L is identifiable with α mind changes iff the accumulation order of L is at most α. Accumulation order is a classic concept from point-set topology. To aid the construction of learning algorithms, we show that the characteristic property of uniformly mind change optimal learners is that they output conjectures (languages) with maximal accumulation order. We illustrate the theory by describing mind change optimal learners for various problems such as identifying linear subspaces and one-variable patterns.

Web malware that targets web applications

Web applications have steadily increased, making them very important in areas, such as financial sectors, e-commerce, e-government, social media network, medical data, e-business, academic an activities, e-banking, e-shopping, e-mail. However, web application pages support users interacting with the data stored in their website to insert, delete and modify content by making a web site their own space. Unfortunately, these activities attracted writers of malicious software for financial gain, and to take advantage of such activities to perform their malicious objectives. This chapter focuses on severe threats to web applications specifically on Structure Query Language Injection Attack (SQLIA) and Zeus threats. These threats could adopt new obfuscation techniques to evade and thwart countermeasures Intrusion Detection Systems (IDS). Furthermore, this work explores and discusses the techniques to detect and prevent web application malwar.

Does privatisation drive innovation? Business model innovation through stakeholder viewpoints: the case of Sydney Airport 10 years post-privatisation

Broad economic and social reform, rapid technological change and increasing global competition have meant that organisations must consider all aspects of their business model in order to successfully create and capture ongoing customer value. In this study it is proposed that business model innovation must always consider and incorporate the symbiotic and interdependent relationship that stakeholders have with an organisation. One particular aspect of economic reform, privatisation, has become an important driver of economic growth in many economies, particularly when linked with the rapid growth of air travel. Privatisation of an airport can generate a radical change in the overall business model for the airport owner and the various stakeholders involved in the operation of the airport. Sydney Airport has restructured its overarching business model to meet the demands of stakeholders. Using feedback from key stakeholders, this research examines the generally accepted view that airport privatisation leads to an improvement in airport performance. Chesbrough's Business Model Framework provides a lens to assist the analysis of Sydney Airport operations before and after privatisation, and provides valuable insights into the impact of privatisation on business model innovation. © Cambridge University Press and Australian and New Zealand Academy of Management 2014.
