This review applauds the initiative to bring together Information Systems Strategy and Strategy-as-Practice research, as in this Special Issue. It highlights especially promising features of each of the empirical articles and develops an agenda for taking some of the themes further. In particular, the review points to opportunities for the intimate comparative investigation of episodes of Infor...

This work aims to develop an accurate model of an existing Photovoltaic Pumping System (PvPS) which is composed of an Ebara Pra-0.50T Asynchronous Moto-Pump (AMP) fed by Kaneka GSA-60 photovoltaic panels via a Moeller DV-51 speed drive. The developed model is then used to compare the performance of the system with its original control strategy based on classical indirect vector control strategy...

Due to high cost and complexity of Intelligent Tutoring Systems (ITS), current systems typically implement a single teaching strategy, and comparative evaluations of alternative strategies are rare. We explore two competing strategies for teaching database normalization. Each data normalization problem consists of a number of tasks, some of which are optional. The first strategy enforces the pr...

We present a simple methodology for incremental development of complex adaptive behaviors in robots. The methodology decomposes a given root strategy into a tree of self-contained supporting strategies that can be fully implemented and tested before the next strategy is added. The methodology also uses comparative performance tests for each new strategy relative to its predecessor. The methodol...

This paper defines head linear reduction, a reduction strategy of λ-terms that performs the minimal number of substitutions for reaching a head normal form. The definition relies on an extended notion of redex, and head linear reduction is therefore not a strategy in the exact usual sense. Krivine’s Abstract Machine is proved to be sound by relating it both to head linear reduction and to usual...

We de ne a perpetual one-step reduction strategy which enables one to construct minimal (w.r.t. L evy's ordering on reductions) in nite reductions in Conditional Orthogonal Expression Reduction Systems. We use this strategy to derive two characterizations of perpetual redexes, i.e., redexes whose contractions retain the existence of in nite reductions. These characterizations generalize existin...

Two radically different views of manufacturing strategy are that it should be developed@om the ‘top down ’ by planned integration with corporate strategy, or alternatively, that it should be developed from the ‘bottom up ’ by focusing on improved performance by the elimination of waste. Using comparative, case-based research, this paper casts some light on these opposing views through quantitat...

The effectiveness of three operational strategies for the control of Triatoma dimidiata was compared by a field trial in the Department of Madriz, Nicaragua. One strategy involved full pretrial evaluation, followed by spraying of all houses irrespective of whether or not they had been found to be infested. The second strategy minimised the pretrial evaluation by considering the locality infeste...

Though the rhesus monkey is one of the most valuable non-human primate animal models for various human diseases because of its manageable size and genetic and proteomic similarities with humans, proteomic research using rhesus monkeys still remains challenging due to the lack of a complete protein sequence database and effective strategy. To investigate the most effective and high-throughput pr...

Collapsed Gibbs sampling is a frequently applied method to approximate intractable integrals in probabilistic generative models such as latent Dirichlet allocation. This sampling method has however the crucial drawback of high computational complexity, which makes it limited applicable on large data sets. We propose a novel dynamic sampling strategy to significantly improve the efficiency of co...
