Enterprise portals: addressing the organisational and individual perspectives of information systems

Enterprise portals are being viewed as the next generation application platform of choice, offering benefits over both client/server and thin client arrangements. By providing a mediating layer between the information applications and resources of the organisation and the individuals using them, enterprise portals appear to provide a unique context to allow both the organisational and individual perspectives of information systems to be addressed. This study seeks to examine these often competing perspectives of information systems by using an exploratory empirical survey to investigate the actual deployment of enterprise portals within a range of different organisations. It is found that both the individual and organisational benefits that enterprise portals can offer appear to have been recognised, and coherent sets of services addressing each of these perspectives are being developed. Consistent with diffusion and acceptance of technology models, organisations appear to be commencing their portal developments with services that will ensure utilisation by individuals, and are subsequently seeking to realise organisational level benefits

A study of subsidiaries views of information systems strategic planning in multinational organisations

This research examines information systems strategic planning (ISSP) in multinationals from the perspective of the subsidiaries. The research was carried out through interviews with the IT and business managers in subsidiaries of nine large American, European, and Japanese multinationals. The evidence from this study reveals that, in the majority of these organisations, IS planning is either centralised or moving towards centralisation. The main focus of IS planning, in many of these organisations, is to control cost and achieve scale economies. As centralisation increases IT tends to control the planning process and, as a result, IS planning becomes more tactical than strategic and is dominated by IT infrastructure planning. Project implementation was the main criterion used to measure IS planning success. However, due to the dominant role of IT, the subsidiary business managers are often less satisfied with the IS planning approach compared with the subsidiary IT managers. The level of involvement of business managers and their satisfaction with ISSP was related to the degree of decentralisation of responsibility for IS planning

The Bioeconomic Implications of A Bycatch Reduction Device as a Stock Conservation Management Measure

The proposed regulation to reduce bycatch and discarding of finfish in the southeastern region is a gear modification that excludes finfish from shrimp trawls. This regulation is analyzed using a simple theoretical model of a multispecies fishery whose bycatch is harvested in a directed fishery consisting of commercial and recreational fishermen. The costless reduction in bycatch fishing mortality imposed on the multispecies fishery does not result in an increased stock size for the bycatch fish species or a substantial increase in its level of harvest. Instead, the fish stock is reallocated from the multispecies fishery to the fishery directed at the bycatch species causing fishing effort to expand in the bycatch species fishery that drives the stock size down to the previously existing equilibrium level. Recreational harvest and effort levels remain unchanged since the model is linear in effort and the commercial fishery is given access to the fishery first.Bycatch, policy analysis, bioeconomic model, Environmental Economics and Policy, Resource /Energy Economics and Policy,

Bounds on Tensor wave and Twisted Inflation

We study the bounds on tensor wave in a class of twisted inflation models where $D(4+2k)$-branes are wrapped on cycles in the compact manifold and wrap the KK-direction in the corresponding effective field theory. While the lower bound is found to be analogous to that in Type IIB models of brane inflation, the upper bound turns out to be significantly different. This is argued for a range of values for the parameter $g_s M$ satisfying the self-consistency relation and the WMAP data. Further, we observe that the wrapped $D8$-brane appears to be the most attractive from a cosmological perspective.Comment: 5 page
