International examples of large-scale systems-theory and practice IV: B2B e-commerce implementation in the Australian context

Two of the most commonly used classifications in IS research are the factor approach and the process approach. While many studies of IS implementation are undertaken using a factor approach, little research so far examines the process of e-commerce implementation, especially in relation to the implementation of e-commerce in business-to-business (B2B) relationships. A holistic understanding of implementation which combines both the factor and process approaches using a case study method, is suggested as particularly suitable because of its ability to capture the reality of e-commerce implementation in an organisation's natural environment and in much greater detail than is possible using one of these approaches alone. In this paper, therefore, we endeavour to contribute to what we perceive as a gap in the body of theory surrounding the implementation process in the business-to-business e-commerce literature. We describe the findings of multiple case studies involving ten major Australian e-commerce initiators. In addition to confirming our earlier finding of the importance of non-technical factors for the success of the implementation process we also present, through our case studies, the various management and business issues associated with the success or failure of B2B e-commerce implementation.

Australian implementation and evaluation of active support

Background The implementation and evaluation of Active Support in Australia is reported, the first such formal evaluation outside the UK.

Method Residents and staff of five group homes participated. Active Support was introduced by training staff in one home at a time. Effectiveness was assessed using direct observation of resident engagement in activity and of staff help, as well as written assessments of resident outcomes.

Results Staff help and resident engagement increased in four of five group homes. There was significantly greater participation in a wider variety of domestic activities, as well as more frequent and varied community participation. Change in resident engagement was positively related to change in staff help, but not related to residents' level of adaptive behaviour.

Conclusions Most of our findings were consistent with earlier UK studies. There was evidence of the successful transfer of Active Support training skills to an Australian training team. Nonsignificant trends towards reduced depression and increased adaptive behaviour warrant further investigation.

Analysis and implementation of swimming backward for biomimetic carangiform robot fish

The swimming backward for biomimetic carangiform robot fish is analyzed and implemented in this paper. The swimming law of the carangiform robot fish is modified according to the European Eel swimming mode based on the multiple-link structure to implement the backward motion. The motion mode difference between the eel and carangiform fish is discussed, and a qualitative kinematic analysis of the carangiform swimming in water is given to analyze the propulsion produced by the undulation of the multi-links tail. The experiments conducted demonstrate the good performance of the proposed method, and the results are given.

An improved method for the purification of rat liver-type fatty acid binding protein from Escherichia coli

We have developed expedient and reliable methods to isolate cyclosporin synthetase for in vitro biosynthesis of cyclosporins. We have examined enzyme purification strategies suited to large-scale processing and present a chromatographic sequence that serves as a pilot model for industrial scale preparation of cyclosporin synthetase from cyclosporin producing fungi. A chromatographic sequence consisting of ammonium sulfate precipitation → gel filtration → hydrophobic interaction chromatography → anion exchange chromatography, yielded an electrophoretically homogeneous cyclosporin synthetase preparation (Coomassie G-250 brilliant blue staining). Furthermore, a native polyacrylamide gel electrophoresis system was developed for the isolation of active cyclosporin synthetase enzyme from crude extracts of cyclosporin producing fungi. The environmental factors affecting enzyme stability and the continuity of the in vitro cyclosporin biosynthetic reaction-temperature, pH, and substrate depletion were assessed and manageable conditions have been defined for sustainable cyclosporin biosynthesis with enzyme isolates. Cyclosporin synthetase exhibited an optimal temperature range of 24–29 °C and a pH optimum of 7.6. The native enzyme displayed a pI of 5.7, as determined by isoelectric focusing. The industrial implementation of an in vitro biosynthetic approach could potentially prove useful for the production of important therapeutic cyclosporins which occur as only minor fermentation by-products.

Evidence for healthy cities : reflections on practice, method and theory

The European Healthy Cities project can be characterized as a social movement that employs an extremely wide range of political, social and behavioural interventions for the development and sustenance of urban population health. At all of these levels, the movement is inspired by ideological, theoretical and evidence-based perspectives. The result of this stance is a dynamic, complex and diverse landscape of initiatives, plans, programmes and actions. In quantitative terms (the number of WHO designated cities and associated cities and communities through national networks), ‘Healthy Cities’ can be regarded as an extraordinary accomplishment and a credit for both WHO and cities in the movement. In qualitative terms, however, critics of the movement have maintained that little evidence on its success and effectiveness has been generated. This critique finds its foundations in the mere perceptions of evidence, the politics of science and urban governance, and perspectives on the preferred or professed utilities of evidence-based health notions. The article reviews the nature of evidence and its interface with politics and governance. Applying a conceptual framework combining insights from knowledge utilization theory, theoretical perspectives on (health) policy development, theory-based evaluations and planned intervention approaches, it demonstrates that, although the evidence is overwhelming, there are barriers to the implementation of such evidence that should be further addressed by ‘Healthy Cities’.

Understanding B2B e-commerce implementation : the evolving Australian experience

This study investigates the implementation process of business-to-business (B2B) e-commerce in Australian organisations. Using a case study method, the study extends substantially theories on Information Systems (IS) implementation. It also suggests an entirely new framework for understanding e-commerce implementation behaviour, which is useful for organisations developing and managing e-commerce initiatives.

Implementation of clinical practice guidelines using simulation in education

Background: Underpinning the Department of Human Services (DHS) “Future directions for Victoria’s maternity services” strategy in Victoria, are the principles of achieving the right balance between primary level care and access to appropriate levels of medical care by making the best use of the complementary skills of midwives, GPs and obstetricians. Planning new models of care have exposed a need to upskill many clinicians in providing evidence based pregnancy care. A statewide education program conducts 1 day workshops to multidisciplinary forums in Victoria. The program content is developed with each service and simulation activities are incorporated in the workshop to provide a realistic environment for practising skills related to the implementation of clinical practice guidelines.

Method: Post workshop surveys are completed anonymously by participants using a five point Likert scale to evaluate their experiences in peer learning, the use of simulation, reflective practice and communication skills training. Open ended responses were analysed thematically.

Results: In 2007, 14 workshops were conducted with 254 clinicians attending. The survey response rate was 80%. Participants responded ‘strongly agree’ or ‘agree’ that the workshop: enhanced their ability to access current pregnancy care research and information 193/ 204(95%), challenged them to think more broadly 192/204(94%), provided an opportunity to reflect on their communication skills during the simulation actives 197/201 (96%) and provided a valuable opportunity for observing the communication skills of their peers 197/ 201(98%).

Conclusion: Providing opportunities for peer learning in pregnancy education is valuable and the use of simulation can play an important role in overcoming barriers to implementing guidelines.

The whole-body fatty acid balance method : examples of its potential for feed efficiency and product quality optimisation in fish and poultry

Dietary lipids and fatty acids are not only fundamental in determining animal performance, but also determine the eating qualities of animal products. Several methods have been used to quantify fatty acid metabolism but most involve expensive in vitro approaches that are not suitable for most laboratories. Furthermore, there is considerable variation between methods with regard to enzyme activity, which makes comparison of results between studies difficult. The recently developed whole-body fatty acid balance method (WBFABM) is a simple and reliable in vivo method for assessing fatty acid metabolism, including rates of liponeogenesis and de novo fatty acid production, β-oxidation of fatty acids and bioconversion (elongation and desaturation) of fatty acids to long-chain polyunsaturated fatty acids. Initially developed for implementation with a fish model, the WBFABM has proven to be a simple and effective method that can be used in any laboratory equipped with a gas chromatography unit. Since its development, it has been used in several farmed finfish feeding trials and in broiler chicken feeding trials. The WBFABM is currently used at research institutions worldwide and its use is increasing in popularity among animal scientists. With this method, it is possible to track the fate of individual dietary fatty acids within the body. The WBFABM could contribute significantly to information generated by animal feeding trials.

Change implementers’ resistance : considering power and resistance in IT implementation projects

Resistance is normally characterized as a set of behaviours located in and belonging to change recipients. Such behaviours are seen to thwart the legitimate aims of both change strategists and the change agents who implement systems and the associated organisational change on the strategists' behalf. However, results from our case study research indicate that resistance can be a property not only of change recipients’ behaviour, but also of change agents and change strategists. The resistance behaviours identified included the failure to follow a prescribed corporate method and template, a refusal to help or listen, a refusal to fix known problems, the display of an adversarial, confrontational, and/or condescending attitude, subversiveness, a poor work ethic, and a refusal to meet requests. This paper argues for a revised conceptualization of resistance as a behaviour that can be demonstrated by any IT project stakeholders, that cannot be divorced from considerations of power in the IT project context.

Managing the implementation of business intelligence systems : a critical success factors framework

The implementation of a BI system is a complex undertaking requiring considerable resources. Yet there is a limited authoritative set of CSFs for management reference. This article represents a first step of filling in the research gap. The authors utilized the Delphi method to conduct three rounds of studies with 15 BI system experts in the domain of engineering asset management organizations. The study develops a CSFs framework that consists of seven factors and associated contextual elements crucial for BI systems implementation. The CSFs are committed management support and sponsorship, business user-oriented change management, clear business vision and well-established case, business-driven methodology and project management, business-centric championship and balanced project team composition, strategic and extensible technical framework, and sustainable data quality and governance framework. This CSFs framework allows BI stakeholders to holistically understand the critical factors that influence implementation success of BI systems.

Optimizing safety, fidelity and usability of an Intelligent Clinical Support Tool (ICST) for acute hospital care: an Australian case study using a multi-method Delphi Process

This research focuses on a major health priority for Australia by addressing existing gaps in the implementation of nursing informatics solutions in healthcare. It serves to inform the successful deployment of IT solutions designed to support patient-centered, frontline acute healthcare delivery by multidisciplinary care teams. The outcomes can guide future evaluations of the contribution of IT solutions to the efficiency, safety and quality of care delivery in acute hospital settings.

A method for stereo-vision based tracking for robotic applications

Vision based tracking of an object using the ideas of perspective projection inherently consists of nonlinearly modelled measurements although the underlying dynamic system that encompasses the object and the vision sensors can be linear. Based on a necessary stereo vision setting, we introduce an appropriate measurement conversion techniques which subsequently facilitate using a linear filter. Linear filter together with the aforementioned measurement conversion approach conforms a robust linear filter that is based on the set values state estimation ideas; a particularly rich area in the robust control literature. We provide a rigorously theoretical analysis to ensure bounded state estimation errors formulated in terms of an ellipsoidal set in which the actual state is guaranteed to be included to an arbitrary high probability. Using computer simulations as well as a practical implementation consisting of a robotic manipulator, we demonstrate our linear robust filter significantly outperforms the traditionally used extended Kalman filter under this stereo vision scenario. © 2008 IEEE.
