An Integrated Search Framework for Leveraging the Knowledge-Based Web Ecosystem
Full text linkThe explosion of information constrains the judgement of search terms associated with Knowledge-Based Web Ecosystem (KBWE), making the retrieval of relevant information and its knowledge management challenging. The existing information retrieval (IR) tools and their fusion in a framework need attention, in which search results can effectively be managed. In this article, we demonstrate the effective use of information retrieval services by a variety of users and agents in various KBWE scenarios. An innovative Integrated Search Framework (ISF) is proposed, which utilises crawling strategies, web search technologies and traditional database search methods. Besides, ISF offers comprehensive, dynamic, personalized, and organization-oriented information retrieval services, ranging from the Internet, extranet, intranet, to personal desktop. In this empirical research, experiments are carried out demonstrating the improvements in the search process, as discerned in the conceptual ISF. The experimental results show improved precision compared with other popular search engines
Applying Complex Adaptive Systems Theory to Understand Distributed Participatory Design in Crowdsourced Information Systems Development
No full textContemporary information systems development (ISD) takes place in a dynamic environment; it is generally acknowledged as a complex activity. It has been proposed that ISD projects should be viewed as a complex adaptive system (CAS) and that these projects are better understood through the application of CAS. Distributed participatory design (DPD) is an approach to contemporary ISD where different, geographically dispersed stakeholders, often called the crowd, participate voluntarily and typically unaffiliated with the development organisation in the development and design of information systems in distributed design teams which are mostly online on Internet, web-based, and social media platforms. Going beyond individual methods, techniques, and practices, the objective of this research is twofold as we answer the two research questions: how are DPD projects in crowdsourced ISD managed and performed in their entirety and how does CAS theory provide plausible explanations and contribute to an understanding of contemporary ISD? For this purpose, we present a case of DPD in crowdsourced ISD in an intergovernmental, not-for-profit environment in the context of a DPD project which engaged Pacific Youth in the development of a digital game where we applied CAS theory to better understand and gain insights for ISD theory and practice
Helping Yourself or Others? Motivation Dynamics for High-Performing Volunteers in GLAM Crowdsourcing
Full text linkWhile most crowdsourcing (CS) cases in the literature focus on commercial organisations, little is known about volunteers’ motivation of initial and continued participation in not-for-profit CS projects and importantly, about how the motivations may change over time. It is vital to understand motivation and motivational dynamics in a not-for-profit context because a fundamental challenge for not-for-profit CS initiations is to recruit and keep volunteers motivated without any formal contract or financial incentives. To tackle this challenge, we explore high performing volunteers’ initial motivation for joining and sustaining with a GLAM (galleries, libraries, archives and museums) CS project. We situated our interpretive exploration in a case study of the Australian Newspapers CS project initiated by the National Library of Australia. Based on the case study, we found that high-performing volunteers were motivated by a combination of personal, collective, and external factors classified into intrinsic, extrinsic, and internalised extrinsic motivations. Further, we found that these motivations changed over time. Specifically, many volunteers presented substantial personal (i.e., personal interest and fun) and community-centric motivations (i.e. altruism and non-profit cause) when they initially joined the project, whereas external motivations (i.e., recognition and rewards) had a greater impact on long-term participation. Our findings offer implications for CS system design (e.g., user profiles, tagging and commenting), incentive structure (e.g., reputation-based ranking, leader boards), and relational mechanisms (e.g., open communication channels) to stimulate sustainable contributions for not-for-profit CS initiatives
A Post Publication Review of 'Understanding the effects of compromise and misuse of personal details on older people'
No full textThis post publication review discusses the article by Watson, Lacey, Kerr, Salmon, and Goode (2019). That article raises important considerations for older people when they interact online. It is a thorough review of the non-financial considerations related to cyber safety for older people in Australia. The authors raise a few issues to consider for future research, but of course like everyone else in the world, they could not foresee the COVID-19 pandemic
Digital Coupon Redemption: Conceptualization, Scale Development and Validation
Full text linkThe purpose of this study is to develop a reliable and valid scale for measuring digital coupon redemption. The scale development process began with the grounded theory approach for item generation. This was followed by the development of a conceptual framework, item generation, initial reliability analysis, exploratory factor analysis and confirmatory factor analysis (CFA) based on primary data collected from 609 participants. For validating the scale, the CFA was repeated using data from 411 unique participants. Results from two independent surveys supported the proposed scale in terms of construct, convergent and discriminant validity. Survey study resulted in a 45-item digital coupon redemption scale. It also covers digital aspects such as intention to search, attitude toward internet searching, perceived risk, perceived convenience and personal innovativeness which were not covered in earlier promotion scales. This scale would assist marketers to maximize digital coupon redemption during their promotion campaigns. This is the first attempt to provide a comprehensive scale to measure digital coupon redemption in the marketing literature
The Challenges Involved in Establishing a Research Technique
Full text linkMany research techniques are well-accepted within the Information Systems (IS) discipline. From time to time, however, a researcher investigates a question that requires a novel approach. It is then incumbent on the researcher to justify that approach. The IS discipline has accumulated a large corpus of published works. A project is being undertaken whose purpose is to establish the conceptual foundations for a research technique for the critical analysis of published works, and to develop methodological guidance for its application. This article discusses the challenges that have confronted that undertaking
The Role of Contextualization in Individuals’ Vulnerability to Phishing Attempts
No full textHackers who engage in phishing manipulate their victims into revealing confidential information by exploiting their motives, habits, and cognitive biases. Drawing on heuristic-systematic processing and the anchoring effect, this study examines how the contextualization of phishing messages, in the form of modifications to their framing and content, affects individuals’ susceptibility to phishing. This study also investigates if there is a discrepancy between the way individuals believe they will react to phishing attempts and their actual reactions. Using two fake phishing campaigns and an online survey, we find that individuals are more susceptible to phishing attempts when the phishing messages they receive are specific to their context, thereby appealing to their psychological vulnerabilities. There is also a significant gap between how individuals believe they will react and their actual reactions to phishing attempts

Towards developing a Healthcare Situation Monitoring Method for Smart City Initiatives: A Citizen Safety Perspective
Full text linkResearch in Smart City development has been proliferated over the past few years, which focused heavily on various supporting service sectors, such as healthcare. However, little effort has been made to design health surveillance support systems, which is also important for the advancement of public healthcare monitoring as an essential smart city initiatives. From an information system (IS) design perspective, this paper introduces a social media-based health surveillance supporting method, which can automatically extricates relevant online posts for health symptom management and prediction. We describe and demonstrate an IS design approach in this paper for hay-fever prediction solution concept based on Twitter posts. This concept can be applicable to fully functional solution design by relevant practitioners in this field
