- Mobile users making real-time decisions based on current information need confidence that their context has been taken into consideration in producing the system's recommendations. This chapter reviews current use of mobile technologies for context-aware real-time decision support. Specifically, it describes a framework for assessing the impact of mobility in decision making. The framework uses dynamic context model of data quality to represent uncertainties in the mobile decision-making environment. This framework can be used for developing visual interactive displays for communicating to the user relevant changes in data quality when working in mobile environments. As an illustration, this chapter proposes a real-time decision support procedure for on-the-spot assistance to the mobile consumer when choosing the best payment option to efficiently manage their budget. The proposed procedure is based on multi-attribute decision analysis, scenario reasoning, and a quality of data framework. The feasibility of the approach is demonstrated with a mobile decision-support system prototype implementation.

- In the debate on the core of Information System (IS), El Sawy identified three faces of IS views: connection, immersion, and fusion. However, no research has further elaborated these concepts. For this task, we adopted the characteristics of the old concept of “emergence” to better describe and explain the shifts in IS from connection to immersion and finally towards fusion. A police organization is examined as a case study, and its Business Intelligence (BI) system and users and their interaction in solving daily tasks are observed. The study took place during two different time periods in 2009 and 2011. Both quantitative and qualitative methods were used, including a survey and interviews. Two main user groups were identified in the police organization: viewers and analysts. The results of this study showed that in the context of viewers BI is in connection view and is slowly emerging into immersion. On the other hand, in the context of analysts BI is positioned in immersion view and, based on emergent properties, we concluded that there is potential for a slow emergence towards fusion once more capabilities are integrated in the BI system used by the analysts.

The role of domain ontology for medical emergency management in mass gatherings

- Mass gatherings are common events that typically attract large crowds of people. If such events are not properly planned, coordinated and managed with regard to health and safety issues, they can become hazardous and lead to injuries, illnesses and deaths. Conducting a safe and successful mass gathering event requires effective planning and management including the provision of timely medical care and response. To achieve these goals, there is a need for a unifying and formal model/framework of mass gatherings that can be applied across all the emergency agencies and events, and used in support of time-critical decision making for medical emergency management in this context. However, the absence of a common knowledge structure and conceptual model in Medical Emergency Management in Mass Gathering (MEMMG), acknowledged in the literature, limits our understanding of such events and impedes the effectiveness of decision support systems in these environments. In this paper, we propose domain ontology for MEMMG that represents main concepts of mass gatherings and their characteristics and relationships in a standard and formal manner. The proposed domain ontology is an instantiation and extension of DOEM (Domain Ontology for Emergency Management) that represents major generic concepts in the emergency management and can be used as information structure for the development of various emergency management decision support systems. We illustrate application of such an ontology to the classical Intelligence-Design-Choice-Implementation decision support model

A framework for a dynamic organizational memory information system
- 1999

- Organizational memory information systems (OMIS) implement important aspects of organizational memory with the aim of enhancing organizational effectiveness. We propose a 3-layered framework for a dynamic OMIS. The framework consists of a pragmatic layer to support the actual activity, a conceptual layer to store the concepts inherent in that activity, and a process layer to store the experience of performing that activity. Both the conceptual and process layers represent organizational memory repositories in the form of respective models. The implementation of OMIS assumes that any activity is the instantiation of relevant conceptual and process models and includes the reuse of knowledge stored in association with those models. In this way, organizational memory is always mapped to current activity, and its adequacy is constantly evaluated. This provides the potential for the models to evolve as a direct result of the current activity. A partial implementation of this framework to support epidemiological research is illustrated.

Conceptual development of an information systems framework for improving continuity in epidemiological research

Tidskriftsartikel (refereegranskat)abstract
- Lack of continuity is a problem for survey-based epidemiological research. Poor access to experience and inadequate retention of information means new projects seldom build on successful predecessors to the maximum possible extent. We have designed a data management framework which addresses this problem using a well-known information systems approach. Our ideas provide a means of storing data in a manner which reflects the original research concepts. This makes collected data accessible and understandable without reference to the questionnaire, and allows new questionnaires to be designed quickly and easily. Our framework provides a means for recording developmental, conceptual and other supporting information and documentation which is traditionally poorly conserved. We illustrate the components of the framework using a major Australian epidemiological project as a case study. Once the necessary software is developed, our framework will improve organisational memory within individual research units and has the potential to become a valuable support tool for survey-based research.
