Designing information systems requirements in context: Insights from the theory of deferred action
This paper considers conceptual and contextual issues relating to the problem of
developing systems models capable of representing knowable and unknowable
information requirements. It postulates that the systemic emergence property of
systems is the cause of unknowable organisational information requirements. The
Theory of Deferred Action and its systems constructs are invoked to explain
emergence and how it can be modelled in formal systems. The insights proposed are
believed to assist designers in developing functional and relevant approaches within
dynamic organisational contexts
Airship logistics: The LTA vehicle; a total cargo system
Design considerations for logistics are dealt with as they pertain to the large rigid LTA vehicle as either a commercial or military cargo carrier. Pertinent factors discussed are: (1) the basic mission; (2) types of payload; (3) the payload space in regards to configuration and sizing, its capacity, and its loadability. A logistic capability comparison of selected cargo airships versus jumbo jets is also made
Ultraviolet and X-ray observations of the BL Lac object PKS 05 8-322
Spectrophotometric observations of the BL Lac object PKS 0548-322 were made with ultraviolet and X-ray instruments on the IUE and HEAO-2 satellites. Two observations in each spectral region, one set of which was obtained simultaneously are presented. A power law of energy index approximately 1.0 gives a good description of the data from ultraviolet through X-ray frequencies. This source is reported to be variable on short timescales (Gilmore 1980); the implications of the spectral properties and apparent variability are discussed in light of a relativistic jet model. Findings support the jet picture of BL Lac objects

e-Government awareness among the techno-disadvantaged in the United States
This exploratory research focuses on awareness among techno-disadvantaged citizens in the United States. Specifically, we address whether awareness is associated with visitation and whether there are differences between those who are aware and those who are not aware. Following up on on a theory-based community initiative designed to improve computer literacy and access to information and communication technologies (ICT) for members of an underserved public housing community, a survey was undertaken. The results indicate that awareness is associated with visitation. Differences in demographic characterisitics, perceived ease of use (PEOU), and perceived access barriers between those who are aware of e-government websites, and those who are not, were found. While nearly half of the respondents are neither aware of nor have visited e-government websites, a slight majority is partaking of e-government services. We identify directions for future research and conclude by emphasizing the value of a theory-based community initiative to improve computer literacy, provide access to ICT, and advance e-government inclusion
Airship economics
Projected operating and manufacturing costs of a large airship design which are considered practical with today's technology and environment are discussed. Data and information developed during an 18-month study on the question of feasibility, engineering, economics and production problems related to a large metalclad type airship are considered. An overview of other classic airship designs are provided, and why metalclad was selected as the most prudent and most economic design to be considered in the 1970-80 era is explained. Crew operation, ATC and enroute requirements are covered along with the question of handling, maintenance and application of systems to the large airship

Strategies, contributions and inhibitors of information systems to organizational competitiveness: An empirical analysis within the Caribbean
The study examines the impact of Information Systems (IS) through a consideration of improved competitiveness within a multi-business Caribbean firm. The methodology draws on a participant-observer approach for data collection and compares the application of IS by three business units within each of three organizations. It is argued that while there is already a substantial amount of research on IS effectiveness its value in the context of developing countries such as those of the Caribbean will be most significant. In this context firms are perceived to face more constraints than in developed countries so there is a need to explicitly recognize the effects of ‘inhibitors’.
The study finds that for two of these businesses IS can be shown to have contributed to improved competitiveness, while the third had a less satisfactory experience. Analysis of the data revealed that in the two business units where IS contributed the units had been able to improve specific business processes in pursuit of identified competitive strategies. In the unit that did not derive such advantages, limitations in the functionality of the core application combined with insufficient adjustment of business processes, led to the unsatisfactory results. It is also observed that the explanatory value of the empirical analysis is enhanced if we identify inhibitors of IS for competitive advantage and make their effects more explicit
Organizational knowledge transfer through creation, mobilization and diffusion: A case analysis of InTouch within Schlumberger
There is a paucity of theory for the effective management of knowledge transfer within large organisations. Practitioners continue to rely upon ‘experimental’ approaches to address the problem. This research attempts to reduce the gap between theory and application, thereby improving conceptual clarity for the transfer of knowledge.
The paper, through an in-depth case analysis conducted within Schlumberger, studies the adoption of an intranet-based knowledge management (KM) system (called InTouch) to support, strategically align and transfer knowledge resources.
The investigation was undertaken through the adoption of a robust methodological approach (abductive strategy) incorporating the role of technology as an enabler of knowledge management application. Consequently, the study addressed the important question of translating theoretical benefits of KM into practical reality.
The research formulates a set of theoretical propositions which are seen as key to the development of an effective knowledge based infrastructure. The findings identify 30 generic attributes that are essential to the creation, mobilisation and diffusion of organisational knowledge.
The research makes a significant contribution to identifying a theoretical and empirically based agenda for successful intranet-based KM which will be of benefit to both the academic and practitioner communities. The paper also highlights and proposes important areas for further research

Evaluating eREVERSE auctions (EeRA): A research note
This eGISE network paper seeks to evaluate issues relating to the implementation of
electronic reverse auctions (eRA) within local government procurement processes. The
adoption of an eRA invites pre-qualified suppliers to compete with each other for a specified
good or service. Consequently, there is a unique opportunity for the buyer to receive a
reduced cost through the successful bidder. However, the literature identifies a number of
adverse effects within these arrangements depending upon the nature of the buyer/supplier
relationship. The objectives of the research involves identifying a set of business scenarios to
demonstrate the impact of different eRA strategies in this respect. This will be achieved
through a structured case analysis approach to enable qualitative data to be modelled through
a visual toolset simulation. It is believed the outcome of the investigation will provide
valuable insights into the complexities associated with the eProcurement process

Factors impacting knowledge transfer success in information systems outsourcing
Despite increased research interest on knowledge transfer in information systems (IS) outsourcing, the field still lacks sound and holistic understanding of the key factors influencing knowledge transfer success. The present paper attempts to provide a synthesis of existing theoretical perspectives and empirical findings related to the factors that facilitate or hamper knowledge transfer success in IS outsourcing. The data collection method is discussed and the key findings are presented. Conclusion is drawn and further research is suggested
