Processing Information Security Messages: An Elaboration Likelihood Perspective

The increasing number of security incidents is causing great concern to organizations. Information security awareness programs are an important approach towards educating users to prevent such incidents. However, it is unclear how to effectively design security programs and messages such that they can inform and change user behaviour. The role of individual factors in influencing the processing of security messages is also unclear. This paper attempts to investigate these problems by studying the effects of security message characteristics and recipient factors on users’ attitude towards security, using the information-processing theory of elaboration likelihood. Two models are developed for this study. The first model studies two message characteristics, argument quantity and quality, as determinants of attitude towards security. A 2x2 factorial design experiment will be conducted to investigate the influence of these characteristics on attitude moderated by the elaboration likelihood towards the security message. The second model tests the effect of four recipient factors on elaboration likelihood. The model development, experimental methodology, and data analysis details are described in this research-in-progress paper. The results are expected to inform the design of effective security messages and contribute to research in this area

Information Systems for Large-Scale Event Management: A Case Study

Information systems (IS) have considerable use in supporting large-scale communication and coordination. This is especially important in contexts such as major event and crisis management which have complex requirements on people and technology. IS facilitate the dissemination of real-time information and coordination among decision makers, and thereby the management of the entire event. This paper describes a case of management and deployment of IS for a large-scale event as an exemplar in this area. Singapore won the bid to host a major international event, the Annual Meetings of the International Monetary Fund and World Bank, collectively known as S2006. However, there were complex requirements and daunting challenges to be overcome in managing such a high-profile and large-scale event. The paper describes how the Committee in charge delivered the IT infrastructure and systems for this large-scale event with 23,700 participants from 184 countries. It suggests several lessons for IT executives in charge of managing large-scale events, mainly for planned (e.g., sports events) and to someextent for unplanned (e.g., Japan tsunami or BP oil spill crisis) events. Particularly, it highlights the need for advance preparedness, use of IS for situation awareness, cultivating relationships for communication and coordination, and the importance of vendor management and project management skills. These lessons are valuable for IS deployment for large-scale communication and coordination for future mega-events and to some degree for preparedness for unforeseen events.

Liver transplantation for acute-on-chronic liver failure

Purpose: To evaluate the outcome of liver transplantation for acute-on-chronic liver failure. Patients and methods: From November 1991 to December 2007, 517 patients underwent liver transplantation at Queen Mary Hospital, Hong Kong. Among them, 149 had acute-on-chronic liver failure as defined in the recent Asian Pacific Association for the Study of Liver Consensus Meeting. Their clinical data were reviewed and their survival outcomes were compared with those of patients who underwent liver transplantation for fulminant hepatic failure and for cirrhosis only in the same period. Results: The patients with acute-on-chronic liver failure included 50 patients having acute exacerbation of chronic hepatitis B and 99 cirrhotic patients with acute deterioration. Their median model for end-stage liver disease scores were 35 and 37, respectively. Preoperative infection (35%), hepatorenal syndrome (38%), and respiratory failure (28.8%) were common. One hundred and three patients received living donor liver grafts and 46 patients received deceased donor liver grafts. The hospital mortality rate was 4.7%. The 5-year survival rates were 93.2% for patients with acute exacerbation of chronic hepatitis B and 90.5% for cirrhotic patients with acute deterioration. The results were similar to those of the patients with fulminant hepatic failure (n = 37) and the patients having cirrhosis only (n = 301). Conclusions: Liver transplantation for acute-on-chronic liver failure is life-saving, and the survival rates it attains are similar to those attained by transplantation for other liver conditions.published_or_final_versionSpringer Open Choice, 21 Feb 201

User Adaptation of Digital Platforms: A Conceptual Framework

The success of a digital platform depends on the number of users, as users co-create value in the ecosystem. However, users may use the platform in unintended ways. Hence, a good understanding of user adaptation of digital platform and its implications is imperative. Most IS studies on user adaptation focus on mandatory use of a system, which is different from the voluntary use of a digital platform. We propose a conceptual framework to examine user adaptation in digital platforms. This research-in-progress paper aims to conduct a case study of user adaptation in a newly-formed digital platform. Our study contributes to the limited research on user adaptation of digital platform, especially giving consideration to the effects upon the ecosystem. Findings can also inform developers in their design of digital platforms to encourage user participation and to cultivate a thriving user community to build and sustain an impactful digital platform ecosyste
