Coalition formation during technology adoption

The Technology Acceptance Model (TAM) is a prominent framework that addresses the challenge of organisations to understand and promote the factors that lead to acceptance of new technologies. Nevertheless, our understanding of one of the model's key variables – social influence – remains limited. Drawing upon earlier studies that address the role of referent individuals to technology acceptance, this paper introduces the notion of ‘coalition’ as a social group that can affect the opinion of other members within an organisation. Our empirical study centres on an organisation that has recently decided to introduce Big Data into its formal operations. Through a unique empirical approach that analyses sentiments expressed by individuals about this technology on the organisation's online forum, we demonstrate the emergence of a central referent, and in turn the dynamics of a coalition that builds around this referent as the attitudes of individuals converge upon the Big Data issue. Our paper contributes to existing TAM frameworks by elaborating the social influence variable and providing a dynamic lens to the technology acceptance process. We concurrently offer a methodological tool for organisations to understand social dynamics that form about a newly introduced technology and accelerate its acceptance by employees.

The influence of technology-mediated environments on international business experience for internationalisation: Does international experience matter?

This paper examines the role and importance of international business experience for firms operating in technologically-mediated environments. Although the key success factors of international expansion have been subject to extensive research in the international business literature, the analysis of technology-mediated environments on international business experience remains limited. This finding is unexpected given that the Internet and the technologies that have enabled it have profoundly transformed the ways in which international business is conducted. This is especially so for firms in the Australian region where the Internet has allowed business to access the scale of markets they need to grow and operate globally (Google and PWC, 2015). Given that businesses of the future will need to innovate quicker and more effectively in online settings to remain competitive, it seems appropriate that we re-visit the more traditional facets of internationalisation; such as the necessity of international business experience for firm performance. In doing so, the empirical section of this paper focuses on twelve Australian international entrepreneurial firms, who in varying degrees utilise technology to leverage their internationalisation activities. The findings suggest that international entrepreneurs with lower levels of international business experience still achieve international performance outcomes. The findings indicate that firms are recognising that the ability to adapt and evolve quickly in technologically-advanced settings is imperative. The findings also suggest that international entrepreneurs are relying less on traditional facets of international business experience, and are learning in self-taught or autodidactic ways. This is because businesses in the current global climate are now operating in complex and highly dynamic environments, characterised by rapid change; thus, the findings suggest that international business experience is becoming less important due to the evolving nature of international business environments.

Playing with Technology: Young Children Making Sense of Technology as Part of Their Everyday Social Worlds

Games and activities, often involving aspects of pretence and fantasy play, are an essential aspect of everyday preschool life for many young children. Young children’s spontaneous play activities can be understood as social life in action. Increasingly, young children’s games and activities involve their engagement in pretence using play props to represent computers, laptops and other pieces of technology equipment. In this way, pretend play becomes a context for engaging with matters from the real world. There are a number of studies investigating school-aged children engaging in gaming and other online activities, but less is known about what young children are doing with online technologies. Drawing on Australian Research Council funded research of children engaging with technologies at home and school, this chapter investigates how young children use technologies in everyday life by showing how they draw on props, both real or imaginary, to support their play activities. An ethnomethodological approach using conversation analysis is used to explore how children’s gestures, gaze and talk work to introduce ideas and activities. This chapter contributes to understandings of how children’s play intersects with technologies and pretend play.

A proposal for a clean technology directive: European patent law and climate change

This article charts the conflicted, dissonant policies of the European Union towards intellectual property and climate change. It contends that there is a mismatch between the empirical work of the European Patent Office and the quietist policy options contemplated by the European Union. This article contends that the European Union needs to develop a Clean Technology Directive to allow for a differentiated approach to patent law and clean technologies - especially given the past complicity of the European Union in global warming and climate change. It highlights essential elements in a comprehensive policy package for the reform of patent law - considering patentable subject matter; patent incentives; and patent exceptions.

Determining reverse salient types and evolutionary dynamics of technology systems with performance disparities

Technological system evolution is marked by the uneven evolution of constituent sub-systems. Subsequently, system evolution is hampered by the resulting state of unevenness, or reverse salience, which results from the presence of the sub-system that delivers the lowest level of performance with respect to other sub-systems, namely, the reverse salient. In this paper, we develop absolute and proportional performance gap measures of reverse salience and, in turn, derive a typology of reverse salients that distinguishes alternative dynamics of change in the evolving system. We subsequently demonstrate the applicability of the measures and the typology through an illustrative empirical study of the PC (personal computer) technological system that functions as a gaming platform. Our empirical analysis demonstrates that patterns of temporal dynamics can be distinguished with the measurement of reverse salience, and that distinct paths of technological system evolution can be identified as different types of reverse salients emerge over time.

Dynamics of reverse salience as technological performance gap: An empirical study of the personal computer technology system

The evolution of technological systems is hindered by systemic components, referred to as reverse salients, which fail to deliver the necessary level of technological performance thereby inhibiting the performance delivery of the system as a whole. This paper develops a performance gap measure of reverse salience and applies this measurement in the study of the PC (personal computer) technological system, focusing on the evolutions of firstly the CPU (central processing unit) and PC game sub-systems, and secondly the GPU (graphics processing unit) and PC game sub-systems. The measurement of the temporal behavior of reverse salience indicates that the PC game sub-system is the reverse salient, continuously trailing behind the technological performance of the CPU and GPU sub-systems from 1996 through 2006. The technological performance of the PC game sub-system as a reverse salient trails that of the CPU sub-system by up to 2300 MHz with a gradually decreasing performance disparity in recent years. In contrast, the dynamics of the PC game sub-system as a reverse salient trails the GPU sub-system with an ever increasing performance gap throughout the timeframe of analysis. In addition, we further discuss the research and managerial implications of our findings.

Influence of pipe length and flow rate on nano-particle deposition in laminar circular pipe flows

The Lagrangian particle tracking provides an effective method for simulating the deposition of nano- particles as well as micro-particles as it accounts for the particle inertia effect as well as the Brownian excitation. However, using the Lagrangian approach for simulating ultrafine particles has been limited due to computational cost and numerical difficulties. The aim of this paper is to study the deposition of nano-particles in cylindrical tubes under laminar condition using the Lagrangian particle tracking method. The commercial Fluent software is used to simulate the fluid flow in the pipes and to study the deposition and dispersion of nano-particles. Different particle diameters as well as different pipe lengths and flow rates are examined. The results show good agreement between the calculated deposition efficiency and different analytic correlations in the literature. Furthermore, for the nano-particles with higher diameters and when the effect of inertia has a higher importance, the calculated deposition efficiency by the Lagrangian method is less than the analytic correlations based on Eulerian method due to statistical error or the inertia effect.

Don't feed the 'patent trolls': [An overhaul of the patent system is necessary to keep up with advances in technology.]

The government is sitting on its hands when an overhaul of the patent system is necessary to keep up with advances in technology in the 21st century.

When the price is not right: Technology price gouging in Australia

Apple Inc. has often portrayed itself as the champion of consumers, with its advertising campaigns on “1984”, “Think Different”, and “Rip, Mix, Burn”. However, this reputation has been called into question after Apple refused to appear before the Parliament’s inquiry into IT Pricing in Australia and explain its pricing policies in Australia.

Hampson type heat-exchanger technology and economic evaluation for LNG re- gasification and power generation At LNG receiving terminals

The system for high utilization of LNG cold energy is proposed by use of process simulator. The proposed design is a closed loop system, and composed by a Hampson type heat exchanger, turbines, pumps and advanced humid air turbine (AHAT) or Gas turbine combined cycle (GTCC). Its heat sources are Boil-off gas and cooling water for AHAT or GTCC. The higher cold exergy recovery to power can be about 38 to 56% as compared to the existing cold power generation of about 20% with a Rankine cycle of a single component. The advantage of the proposed system is to reduce the number of heat exchangers. Furthermore, the environmental impact is minimized because the proposed design is a closed loop system. A life cycle comparative cost is calculated to demonstrate feasibility of the proposed design. The development of the Hampson type exchangers is expected to meet the key functional requirements and will result in much higher LNG cold exergy recovery and the overall system performance i.e. re-gasification. Additionally, the proposed design is expected to provide flexibility to meet different gas pressure suited for the deregulation of energy system in Japan and higher reliability for an integrated boil-off gas system.

An investigation of Nano-particle deposition in cylindrical tubes under Laminar condition using Lagrangian transport model

Aerosol deposition in cylindrical tubes is a subject of interest to researchers and engineers in many applications of aerosol physics and metrology. Investigation of nano-particles in different aspects such as lungs, upper airways, batteries and vehicle exhaust gases is vital due the smaller size, adverse health effect and higher trouble for trapping than the micro-particles. The Lagrangian particle tracking provides an effective method for simulating the deposition of nano-particles as well as micro-particles as it accounts for the particle inertia effect as well as the Brownian excitation. However, using the Lagrangian approach for simulating ultrafine particles has been limited due to computational cost and numerical difficulties. In this paper, the deposition of nano-particles in cylindrical tubes under laminar condition is studied using the Lagrangian particle tracking method. The commercial Fluent software is used to simulate the fluid flow in the pipes and to study the deposition and dispersion of nano-particles. Different particle diameters as well as different flow rates are examined. The point analysis in a uniform flow is performed for validating the Brownian motion. The results show good agreement between the calculated deposition efficiency and the analytic correlations in the literature. Furthermore, for the nano-particles with the diameter more than 40 nm, the calculated deposition efficiency by the Lagrangian method is less than the analytic correlations based on Eulerian method due to statistical error or the inertia effect.

Holistically approaching curriculum renewal: A case study of the Queensland University of Technology

There are still many programs in Australia and overseas where curricula comprise largely 20th Century-relevant graduate outcomes, framed in 20th Century learning and teaching approaches. A ‘Dynamic and Deliberative Model for Curriculum Renewal’ (DDMCR) model exists for undertaking such curriculum renewal that draws on the experiences of educators around the world, however there are few experiences to date in applying this model. At the Queensland University of Technology, the 2012 accreditation by Engineers Australia observed that, despite being exposed to relevant discipline-specific engineering curriculum and practice, students did not seem to be aware of the relevance of sustainable development to their degree, beyond first year exposure. In addressing this feedback, level 8 Australian Qualifications Framework, and drawing ideas from the DDMCR model, faculty senior management undertook a full review of the engineering curriculum.

Technology-mediated tools for shaping experiences in urban commuter trains

This thesis presents the results of a study into ways that technology can be appropriated and designed to support urban rail commuters in their daily journeys. The study evaluated a mobile application prototype deployed along the Brisbane passenger rail network. This prototype was designed to support social interaction between passengers sharing the same trains. This thesis provides a step forward in showing the relevance of increasingly creating solutions that contribute to a more enjoyable and attractive public transport service.

An integrated framework for theories of individual attitudes toward technology

Theories of individual attitudes toward IT include task technology fit (TTF), technology acceptance model (TAM), unified theory of acceptance and use of technology (UTAUT), cognitive fit, expectation disconfirmation, and computer self-efficacy. Examination of these theories reveals three main concerns. First, the theories mostly ‘‘black box’’ (or omit) the IT artifact. Second, appropriate mid-range theory is not developed to contribute to disciplinary progress and to serve the needs of our practitioner community. Third, theories are overlapping but incommensurable. We propose a theoretical framework that harmonizes these attitudinal theories and shows how they can be specialized to include relevant IS phenomenon.
