During the last years a great number of Query Performance Prediction methods have been proposed. However, this explosion of prediction method proposals have not been paralleled by an in-depth study of suitable methods to evaluate these estimations. In this paper we analyse the current approaches to evaluate Query Performance Prediction methods, highlighting some limitations they present. We als...

We present an overview of current research in performance modeling, focusing on efforts underway in the Performance Evaluation Research Center (PERC). Using some new techniques, we are able to construct performance models that can be used to project the sustained performance of large-scale scientific programs on different systems, over a range of job and system sizes. Such models can be used by...

Analysis of event-related potential (ERP) data includes several steps to ensure that ERPs meet an appropriate level of signal quality. One such step, subject exclusion, rejects subject data if ERP waveforms fail to meet an appropriate level of signal quality. Subject exclusion is an important quality control step in the ERP analysis pipeline as it ensures that statistical inference is based onl...

many countries are turning their attention to the use of explicit financial incentives to drive desired improvements in healthcare performance. however, we have only a weak evidence-base to inform policy in this area. the research challenge is to generate robust evidence on what financial incentives work, under what circumstances, for whom and with what intended and unintended consequences.

This study compares the financial performance trend of successful and less successful ERP implementers over three years following the implementation. The findings indicate no significant difference in the change in ROA and ROI of the two groups of adopters. Successful ERP adopters however have statistically significant higher efficiency benefits in terms of Asset Turnover and Capital Turnover t...

One of the current research trends in Enterprise Resource Planning (ERP) involves examining the critical factors for its successful implementation. However, there is limited beyond system implementation, focusing on flexibly of ERP to respond to changes in business. Therefore, this study explores a combination system, involving an ERP system and informality, which focus on providing a company w...
