Governments in developing countries are spending more and more money on antiretroviral medication programs in hope that the programs curb the spread of HIV/AIDS and reduce the suffering of those infected. This makes the question of determining the optimal mix of prevention and medication ever more pressing. We construct and parameterize a model of the spread of HIV/AIDS in Botswana that allows ...

Operational risk and outsourcing are two major topics on today's agenda of top executives, especially in the banking industry. This paper introduces a framework to classify operational risk in outsourcing in a way that generates quantifiable output for measurement purposes. The authors developed a matrix system that deploys a catalogue of sources of risk and a mutually exclusive yet exhaustive ...

The single most important number in the accounts of a non-life insurance company is likely to be the estimate of the outlying liabilities. Since nonlife insurance is a major part of our financial industry (amounting to up to 5% of BNP in western countries), it is perhaps surprising that mathematical statisticians and experts of operational research (the natural experts of the underlying problem...

Identifying rigorous and relevant research methods has for a long time been a challenge in IS research. This is amplified in developing countries, where understanding the context is key. This paper presents an Action Design Research based approach, incorporating ethnography, which aims to provide a more authentic and relevant analysis. The Action Design Ethnographic Research (ADER) method is il...

With the operational capability for large-scale machine translation on the immediate horizon, documentalists must become aware of what new problems they must face. The state of the art of machine translation is briefly reviewed. The magnitude of the translation problem is documented with data from the Soviet scientific and technical press. The parameters of input to a mechanized system; of tran...

The technology industry has received poor marks on its ability to deliver successful projects on time and on budget. According to Sribar & Passori [32], 72% of all IT projects are late, over budget, lack functionality, or are never delivered as planned. Varley [36] suggested that poor communications, unrealistic expectations, competing agendas, resistance to change, and lack of agreed upon metr...

Multidisk vertical allocation (MDVA) problems intend to find an allocation of relations to disks such that the expected query cost is minimized. Recently, Chang [European Journal of Operational Research 143 (2002) 210] modified Rotem et al.’s [IEEE Transactions on Knowledge and Data Engineering 5 (1993) 882] method for solving an MDVA problem using a smaller number of binary variables. Chang’s ...
