In this proposal we present some directions to attack the problem of indexing bitemporal databases, which, up to date, has not been addressed in the literature. To achieve that we do the following. We review the models for historical, rollback and bitemporal databases. For the historical and roolback models we present several indexing approaches presented in the literature. We then propose the indexing structures to be investigated towards the goal of indexing bitemporal databases. In order to evaluate such indexing structures we need to address the design of sets of data and queries accordingly. Finally, we present the deliverables of the research to be pursued and a schedule to be followed. |

In this paper we use a Zero Sum Gains Data Envelopment Analysis model (ZSG-DEA) to allocate financial resources for competitive projects managed by the Brazilian Agricultural Research Corporation (Embrapa) research centers. The initial output measurement in the production process modeled is the amount of financial resources available, uniformly distributed among research centers. The input variables are proxies for the intensity of projects externally funded, quality of project management, and level of participation in complex researches. The allocation proposed has maximum global efficiency. |
