In this paper we first point out a puzzle regarding the nature of US business cycles over the last thirty years. As is well known, over this period the economy experienced three main cycles. In each case, the common narrative behind these cycles has been that they were in large part driven by demand (residential investment demand in the 2000s, “tech” investment demand in the 1990s, and commerci...

This artifact is a proof-of-concept implementation of DDPA, an on-demand program analysis for higherorder functional programs. The implementation, written in OCaml, includes a parser, evaluator, and DDPA analysis for the language defined in the companion paper (including the proper record semantics extension). The analysis may be performed using different levels of precision as specified by the...

Post-Occupancy Evaluation (POE) has become increasingly accepted and influential among client organizations responsible for large building management and construction programs. Managers and administrators look to POE to provide answers to· important facilities questions. This increased focus on decision-making has resulted in a number of changes to the way in which POEs are conducted, including...

ulate the transition between self-renewal and differentiation stage in different systems, and both are associated with the maintenance of the progenitor state. The general question that arises is how those signals are integrated within otic progenitors so that they result in a precise cell diversification. We have studied the interactions between Sox2 and Notch pathways in otic neurosensory pro...

Program slicing is a technique to extract relevant parts of a program, and it is widely used in program debugging, parallelization, testing, reverse engineering, etc. This paper concerns static slicing and it follows the Weiser’s definition of slicing that consists of computing what statements of the program might affect the value of some particular variable at a specified program point. We arg...

Recent interest in “evidence-based policy-making” is a response to the perception that governments need to improve the quality of their decisionmaking in view of rapid changes and scarce resources.1 Creating better policies means using the best available evidence and not merely that which is the most easily accessible. In a world of information overload, there is a large amount of information t...

Ray tracing is a powerful technique to generate realistic images of 3D scenes. A drawback is its high demand for processing power. Multiprocessing is one way to meet this demand. However, when the models are very large, special attention must be paid to the way the algorithm is parallelised. Combining demand driven and data parallel techniques provides good opportunities to arrive at an efficie...

The capability of dynamically monitoring the performance of the communication infrastructure is one of the emerging requirements for a Grid. We claim that such a capability is in fact orthogonal to the more popular collection of data for scheduling and diagnosis, which needs large storage and indexing capabilities, but may disregard real-time performance issues. We discuss such claim analyzing ...

Despite their explicit focus on reaching the poor, many community driven development (CDD) initiatives are only partially successful in targeting spending towards them. This paper examines Tanzania’s flagship CDD program and provides new evidence on the mechanisms by which the demand-driven components of the program may undermine the goal of pro-poor funding allocations. We exploit two data sou...
