despite several authors having studied the strategic approach to environmental orientation and,considering that environmental proactivity is emerging in business strategy, it still remains unclear which realactions influence a firm’s environmental orientation. an empirical analysis of a sample of 126 spanish companies shows that firms’ actions are explained as training, information and divulgat...

Several studies of multiprogrammed parallel systems have observed that dynamic equiallocation policies have high performance for a variety of speciic parallel workloads. However, only very incomplete information is available about which workload parameters are key determinants of policy performance and how the mean response times of equiallocation policies behave as a function of key workload p...

This paper considers models of educational data where a valueadded analysis is required. These models are multilevel in nature and contain endogenous regressors. Multivariate models are considered so as to simultaneously model results from different subject areas. Path models and factor models are considered as types of model that can be used to overcome the problem of endogeneity. Estimation m...

This paper improves upon previous synthetic workload models and compares the performance of dynamic spatial equipartitioning (EQS) and the semi-static quantum-based FB-PWS processor allocation deened in 23], under synthetic workloads that have not previously been considered. These new workloads include realistic repartitioning overheads and job characteristics that are consistent with system me...

Whereas measures of explained variance in a regression and an equation of a recursive structural equation model can be simply summarized by a standard R2 measure, this is not possible in nonrecursive models in which there are reciprocal interdependencies among variables. This article provides a general approach to defining variance explained in latent dependent variables of nonrecursive linear ...

Whether electromagnetic precursors to earthquakes (EQs) exist is an important question not only for EQ prediction but also for understanding the physical processes of EQ generation. Slow transient geoelectric potential changes have been observed before several recent EQs in Japan. In most cases, they appeared 1-19 days before the EQs, and their duration and intensity were several minutes to 1 h...
