Unveiling the Black Markets of Pooled Assets
Get PDFPresence of black markets is not common for every industry but is a unique phenomenon in the industries such as asset pooling and leasing services. The unique business models and the asset flows that we see in such industries are susceptible for such threats and reveals the nature and extent of extent of industry-specific threats. This paper employs agility lens (Overby et al. 2006; Roberts and Grover 2012) to understand how such firms could address the issue of black market threats with the help of network structure. Through a case study of a global asset pooling and leasing company, we reveal the criticality of network structures, the difficulties, inadequacies and impracticalities of current tracking technologies that challenge firms in minimizing such threats
Multi-Objective Decision Analytics for Short-Notice Bushfire Evacuation: An Australian Case Study
Get PDFThis paper develops a multi-objective optimisation model to compute resource allocation,shelter assignment and routing options to evacuate late evacuees from affected areas to shelters.Three bushfire scenarios are analysed to incorporate constraints of restricted time-window and potential road disruptions.Capacity and number of rescue vehicles and shelters are other constraints that are identical in all scenarios.The proposed mathematical model is solved by ?-constraint approach.Objective functions are simultaneously optimised to maximise the total number of evacuees and assigned rescue vehicles and shelters.We argue that this model provides a scenario-based decision-making platform to aid minimise resource utilisation and maximise coverage of late evacuees
Addressing the Complexities of Big Data Analytics in Healthcare: The Diabetes Screening Case
Get PDFThe healthcare industry generates a high throughput of medical, clinical and omics data of varying complexity and features. Clinical decision-support is gaining widespread attention as medical institutions and governing bodies turn towards better management of this data for effective and efficient healthcare delivery and quality assured outcomes. Amass of data across all stages, from disease diagnosis to palliative care, is further indication of the opportunities and challenges to effective data management, analysis, prediction and optimization techniques as parts of knowledge management in clinical environments. Big Data analytics (BDA) presents the potential to advance this industry with reforms in clinical decision-support and translational research. However, adoption of big data analytics has been slow due to complexities posed by the nature of healthcare data. The success of these systems is hard to predict, so further research is needed to provide a robust framework to ensure investment in BDA is justified. In this paper we investigate these complexities from the perspective of updated Information Systems (IS) participation theory. We present a case study on a large diabetes screening project to integrate, converge and derive expedient insights from such an accumulation of data and make recommendations for a successful BDA implementation grounded in a participatory framework and the specificities of big data in healthcare context
Improving professional IT doctorate completion rates
Get PDFProfessional doctorates in Information Technology (IT) have been a relatively recent phenomenon, giving IT professionals career management choices not previously available to them. However, successful completion rates are the lowest of all disciplines. Completed doctorates rate in quality equivalent to PhDs, and retention has been identified as a major obstacle to completion. This qualitative study, involving 44 semi-structured interviews with students, supervisors and institutional support personnel, investigated the obstacles. Amongst the strategies discovered to improve completion rates were retention, student engagement with supervisors, feedback on progress, student engagement in the course, and student involvement in institutional communities of practice

A mathematical model for the municipal solid waste location-routing problem with intermediate transfer stations
Get PDFMunicipal solid waste management is one of the challenging issues in mega cities due to various interrelated factors such as operational costs and environmental concerns. Cost as one of the most significant constraints of municipal solid waste management can be effectively economized by efficient planning approaches. Considering diverse waste types in an integrated municipal solid waste system, a mathematical model of the location-routing problem is formulated and solved in this study in order to minimize the total cost of transportation and facility establishment
Enhancing client welfare through better communication of private mental health data between rural service providers
Get PDFClient welfare is detrimentally affected by poor communication of data between rural service providers, which in part is complicated by privacy legislation. A study of service provision involving interviews with mental health professionals, found challenges in communicative processes between agencies were exacerbated by the heavy workloads. Dependence on individual interpretations of legislation, and on manual handling, led to delays that detrimentally affected client welfare. The main recommendation arising from this article is the creation of an ehealth system that is able to negotiate differing levels of access to client data through centralised controls, where the administration of that system ensures that it stays current with changing legislative requirements. The main contribution of the proposed model is to combine two well-known concepts: data integration and generalisation. People with mental illness are amongst the most vulnerable members of society, and current ehealth systems that provide access to medical records inadequately cater to their needs
Innovation Determinants and Barriers: A Tri-Perspective Analysis of IT Appropriation within an Early Childhood Education and Care Organisation
Get PDFEmpirical studies on information technology (IT) in early childhood education and care organisations are scant, despite an increasing number of these organisations choosing to innovate with IT. This paper presents a framework to understand the appropriation of IT as an innovation within such an organisation. The framework consists of three perspectives on innovation: an individualist, a structuralist and an interactive process perspective. While the first focuses on concepts such as leadership, IT champions, previous IT exposure, the second focuses on organisation size, parents as stakeholders, competitors, government compliance and regulatory requirements. The third perspective views the innovation as a dynamic phenomenon of change, produced by the continuous interaction of the innovation content, its context, and the appropriation process as related in an interactive process. We demonstrate the framework’s applicability and determine that the three perspectives supplement each other and together provide a deeper understanding of the IT appropriation process in terms of innovation determinants and barriers
Knowledge Sharing in IT Consultant and SME Interactions
Get PDFMany small and medium enterprises (SMEs) depend on consultants to overcome knowledge barriers, especially for IT projects. This paper aims to determine how IT consultants affect the IT knowledge of SMEs when IT consultants and SMEs interact. Data were collected using face-to-face interviews with both IT consultants and SME managers. The study is the first to identify what and how SMEs learn from consultants during an IT implementation project. Consultants help SMEs gain different types of knowledge, employing a broad range of knowledge sharing mechanisms. As consultants are an important part of the knowledge creation processes of SMEs, SMEs should strive to form long-term relationships with consultants and use these interactions to develop IT knowledge within the SME
