How intimate are Australian e-business retail supply chains?

The adoption of electronic commerce strategies is becoming an important means of assisting industries, and indeed whole economies, to gain significant net benefits. The extent to which e-commerce-based strategies, such as quick response and efficient consumer response, might have an effect on local economies depends in part on how readily they are being adopted. The dominant form of adoption of these strategies is to be found in the business-to-business forms of e-commerce. To be successful, business partners must be in a position to develop customer intimacy through sharing of information, to improve their stock replenishment practices, and enhance their levels of online customer support. This paper presents the initial results of a national survey completed in the retail sector of the Australian economy, that assesses how well Australian industry is responding to these e-commerce challenges.

Robust extended Kalman filter based technique for location management in PCS networks

Provisioning of real-time multimedia sessions over wireless cellular network poses unique challenges due to frequent handoff and rerouting of a connection. For this reason, the wireless networks with cellular architecture require efficient user mobility estimation and prediction. This paper proposes using Robust Extended Kalman Filter as a location heading altitude estimator of mobile user for next cell prediction in order to improve the connection reliability and bandwidth efficiency of the underlying system. Through analysis we demonstrate that our algorithm reduces the system complexity (compared to existing approach using pattern matching and Kalman filter) as it requires only two base station measurements or only the measurement from the closest base station. Further, the technique is robust against system uncertainties due to inherent deterministic nature in the mobility model. Through simulation, we show the accuracy and simplicity in implementation of our prediction algorithm.

Towards extended machine translation model for next generation world wide web

In this paper, we proposed a Data Translation model which potentially is a major promising web service of the next generation world wide web. This technique is somehow analogy to the technique of traditional machine translation but it is far beyond what we understand about machine translation in the past and nowadays in terms of the scope and the contents. To illustrate the new concept of web services based data translation, a multilingual machine translation electronic dictionary system and its web services based model including generic services, multilingual translation services are presented. This proposed data translation model aims at achieving better web services in easiness, convenience, efficiency, and higher accuracy, scalability, self-learning, self-adapting.

An extended negative selection algorithm for anomaly detection

This paper proposes an extended negative selection algorithm for anomaly detection. Unlike previously proposed negative selection algorithms which do not make use of non-self data, the extended negative selection algorithm first acquires prior knowledge about the characteristics of the Problem space from the historial sample data by using machine learning techniques. Such data consists of both self data and non-self data. The acquired prior knowledge is represented in the form of production rules and thus viewed as common schemata which characterise the two subspaces: self-subspace and non-self-subspace, and provide important information to the generation of detection rules. One advantage of our approach is that it does not rely on the structured representation of the data and can be applied to general anomaly detection. To test the effectiveness, we test our approach through experiments with the public data set iris and KDDrsquo99 published data set.

The psychological impact of extended temporary protection

Against the background of the recent international trend of a greater reliance on deterrence measures in managing the flow of asylum seekers, this paper discusses the implementation of the temporary protection visa (TPV) in Australia. It focuses on the psychological impact of the TPV policy on individual asylum seekers and how this unlimited temporary status affects the overall process of settlement. This study is based on personal narratives constructed by individual asylum seekers during one-on-one interviews aimed at sketching the mental and psychological manifestations of stressful events in their lives as TPV holders. What is particularly revealing among many of these TPV holders is the fact that their pre-migration traumatic experiences are compounded by a post-migration condition of being in indefinite "temporary" protection. This is further exacerbated by a prevalence of racialized discourses and exclusionary policies advocated by the host government. Past trauma and persecution, combined with present family separation and social exclusion, and further compounded by uncertainty about the future, had resulted in almost chronic states of anxiety and depression among a significant number of TPV holders.

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.

Robust extended kalman filter applied to location tracking and trajectory prediction for PCS networks

Provisioning of real-time multimedia sessions over wireless cellular network poses unique challenges due to frequent handoff and rerouting of a connection. For this reason, the wireless networks with cellular architecture require efficient user mobility estimation and prediction. This paper proposes using robust extended Kalman filter (REKF) as a location heading altitude estimator of mobile user for next cell prediction in order to improve the connection reliability and bandwidth efficiency of the underlying system. Through analysis we demonstrate that our algorithm reduces the system complexity (compared to existing approach using pattern matching and Kalman filter) as it requires only two base station measurements or only the measurement from the closest base station. Further, the technique is robust against system uncertainties due to inherent deterministic nature in the mobility model and more effective in comparison with the standard Kalman filter.

Innovation chains: possibilities and constraints for critical perspectives on computers, difference and educational innovation

While declarations of ‘innovativeness’ are easily found in most educational contexts, it is significantly more difficult to locate detailed definitions of what educational innovation actually means. In this paper we are interested in identifying the extent to which mainstream takes on ‘innovation’ (as played out in contemporary technology and equity debates) reflect or respond to what we will define as the more innovative dimensions of innovation literature itself. Our aim throughout this paper, then, is to begin the complex process of developing a means for distinguishing between projects that are ‘badged’ as innovative and projects that are more demonstrably (and sustainably) innovative. In this process we will distinguish between what Shiv Visvanathn describes as “innovation chains”— dynamic, rhizomatic, transformative responses to the contemporary world that lead to fundamentally new ways of conceptualising technology, culture and difference—and the constraints—or chains—provided by dominant understandings of innovation: chains which anchor us to existing, hegemonic and limiting understandings of student
diversity and educational technology.

Playing with time: history and the extended present

In this paper we consider how the concept of time is developed in schools. We argue that the teaching and learning of history (despite the emergence of the new history in the 1970s) is still taught and learnt with a temporal bias and it is often positioned in the past. So too, history/SOSE1 student-teachers are exposed to temporal bias in their tertiary education (as is evidenced in ‘Arts Faculty’ history courses). We suggest that there needs to be greater connectedness and balance between the dimensions of time in the teaching of SOSE with specific reference to the teaching of history and futures perspectives. We offer a new conceptualisation of history which we refer to as ‘history as the extended present’ this conceptualisation positions history in multiple temporal domains (the past, present and possible, probable and preferable futures) and emphasises the relevance of teaching and learning history to students life worlds.

Embodied energy in buildings : wood versus concrete - reply to Börjesson and Gustavsson

We analyse the wood and concrete designs of the Wälludden building described by Börjesson et al. (Energy Policy 28 (2000) 575) in terms of their embodied energy, employing an environmentally extended input–output framework in a tiered hybrid life-cycle assessment, and in a structural path analysis. We illustrate the complexity of the inter-industry supply chains underlying the upstream energy requirements for the building options, and demonstrate that higher-order inputs are difficult to capture in a conventional process analysis. Our calculations show that Börjesson and Gustavsson's estimates of energy requirements and greenhouse gas emissions are underestimated by a factor of about 2, and that corresponding greenhouse gas balances are positive at about 30 t C-eq. Nevertheless, Börjesson and Gustavsson's general result—the concrete-framed building causing higher emissions—still holds.

2-(2-Pyridylamino)Pyridinium2-(2-Pyridylamino)pyridinium chloride phosphorous acid: one-dimensional hydrogen-bonded and [π]-[π] stacked supramolecular chains

In the crystal structure of the title compound, C₁₀H₁₀N₃⁺·Cl-^·[P(O)(OH)₂H], the chloride ion and phosphorous acid form a one-dimensional hydrogen-bonded chain, while the 2-(2-pyridylamino)pyridinium cations form a second chain through [π]-[π] stacking. The two parallel chains are connected via a PO...H-N hydrogen bond and a weak pyridinium-to-chloride interaction.

A construct of sequential service quality in service encounter chains

Studies of the construct of service quality have traditionally been undertaken from the perspective of the service receiver. More recently, research has focused on both the service provider's perspective and the service receiver's perspective. In addition, there have also been some triadic network approaches to the study of service quality. However, there has been very little research into sequential service quality in service-encounter chains (that is, consecutive service performances in a series of service encounters). The incorporation of connected service encounters in services management can improve understanding of sequential service quality in service-encounter chains. This paper provides a customized construct of sequential service quality and  highlights the importance of time, context, and performance threshold in service-encounter chains. Furthermore, the paper presents a customized six-dimensional construct of sequential service quality.
