The Growing Impact of Shadow IT on Higher Education by Owen Hall Jr. Abstract: The problems associated with Shadow IT (SIT) continue to grow throughout higher education. Some of the challenges include cybersecurity concerns, noncompliance with regulatory requirements, and end user-built applications that are not coded to institutional standards. In todays digital economy, end users have an expanding number of IT options and recent data suggest that these end users are increasingly using SIT in support of their work and school assignments. The results of a survey based on the ground theory model identified a number of categories that help explain the dynamics between end users and central IT. A causal loop model was then applied to the task of resolving these qualitative-based conflicts, paving the way for developing of an amelioration plan. The purpose of this article is to introduce the Hybrid-driven IT model, which is designed to establish the most appropriate level of SIT that optimizes overall institutional IT performance. Keywords: Shadow IT; higher education; hybrid-driven IT model; grounded theory; causal loop diagrams; online learning.
Evaluating Consumer Food Safety Mobile Applications: Lessons Learned from Combining Assessment of Users, Usability & Context by Adeola Bamgboje-Ayodele, Leonie Ellis, Paul Turner Abstract: Numerous consumer food safety mobile applications (apps) are aimed at mitigating health risks arising from poor lifestyle, nutrition and domestic food poisoning due to unsafe food handling. There is limited research evaluating the effectiveness of these apps in mitigating specific health risks; and how consumers adopt and use these apps. The few existing evaluations have marginalised questions about the importance of contexts of use and the attributes and behaviours of end-users. This paper describes an over-arching evaluation approach to address these issues. The approach adapted a heuristics framework and combined it with a consumer-based evaluation (CBE) to holistically assess the usability of these apps, their contexts of use and the attributes of end-users. The paper further presents detailed research findings, generated from the CBE of three food safety mobile apps, which is the focus of this paper. This CBE was conducted through scenario-based focus groups session with nine Australian consumers using card sorts. The results identify three application design considerations recommended to enhance apps that provide consumers with safe food handling information. This is part of a broader research focused on improving understanding of how best to enhance consumer food safety and mitigate health risks associated with unsafe food handling. Keywords: Usability; Heuristics Evaluation; Consumer Evaluation; Food Safety; Mobile Applications.
The Impact of ICT Tools on New Product Development Performance and Collaboration by C. W. Chathurani Silva, Sanjay Mathrani, Nihal Jayamaha Abstract: New product development (NPD) practitioners increasingly rely on information and communication technology (ICT), aiming to achieve lower costs, higher quality and greater speed to market. Only a little is known about the effect of various ICT tools on NPD performance, and exploring this would ease effective deployment of technological resources in innovation programmes. This study uses data collected in the Product Development Management Associations 2012 Comparative Performance Assessment Study, from 450 firms across different countries and industries. The direct and indirect effects of thirteen ICT tools on overall NPD performance are examined using hierarchical regression analysis. Results suggest that six ICT tools indirectly improve NPD performance by increasing collaboration, while the direct effects of PDM systems and project management systems are significant. The study implies that extensive use of ICT significantly contributes to improve collaboration, which is vital for achieving the NPD programmes objectives, increasing competitiveness, and improving overall NPD performance. Keywords: ICT; new product development performance; collaboration; organizational information processing theory; relational resource-based view.
Bi-temporal Versioning of Changing Measures in Bitemporal Data Warehouses by Anjana Gosain, Kriti Saroha Abstract: Bi-temporal data warehouse (BTDW) design that extends the multidimensional model, uses bitemporal (combination of valid time and transaction time) timestamps on the members of multidimensional data in order to manage time-varying data. Various approaches to manage changes of schema and dimension data in BTDW exist that use the combination of both valid-time as well as transaction-time. Also, measures/ facts can undergo change with time However, current BTDWs do not handle or track changes for dynamic measures. This would pose problem for applications like fraud detection, where it is required to know and record the time when changes have occurred in the system; schema, dimension data or measures. Thus, the changes occurring in the measures need to be recorded indicating the time when a specific measure value is valid or updated. In this work, we propose solution for handling time-varying measures using bi-temporal versioning of fact table schema and fact data along with storage options for handling and storing the separate versions of fact table schema and data. Keywords: data warehouse; bi-temporal data warehouse; schema versioning; transaction-time; valid-time; bi-temporal; facts; measures.
The Impact of Interactive Design as a Conversion Rate Optimization tool for E-Commerce by Anas Rano, Roopesh Kevin Sungkur Abstract: E-commerce has become a vital and integral part of everyday life even more so in the business world, its development and growth is well documented. The performance figures which are an evidence of its growth are published yearly. Despite the impressive figures that it displays, there has long been a serious issue with regards to conversion rates (CR), which have been estimated to be below 5% as far back as 2008.This research investigated the phenomena in a series of phases using an e-commerce website as the case study. The A/B testing framework was used to investigate the possible factors responsible for low conversion rate in an e-commerce website and a number of solutions were provided. Focusing on how the use of interactive design, Human Computer Interaction principles, and industry design standard could be adopted as a tool to enhance the conversion rate of an e-commerce website. These design factors were used in the creation of a web application which was tested in a comparative assessment with a case study website to prove that the new design enhancements resulted in an improvement in the performance of the new website. This resulted in the new website reporting an increase website usability and enhanced user experience, which ultimately lead to an increase in conversion rates.
