The quality of several colour image difference metrics, pixelwise CIELAB DEab, S-CIELAB, iCAM, Structural Similarity Index, Universal Image Quality and the hue-angle algorithm, have been investigated. These results were compared with the results from a psychophysical experiment in which the perceptual image difference was evaluated. Six original images were reproduced using six different colour...

A process performance management system (PPMS) helps to plan, monitor, and improve the performance of business processes. In PPMS, process-focused key performance indicators (KPIs) are used to evaluate the actual process performance and to improve business processes and, subsequently, corporate performance. The empirical study focuses on PPMS and its success factors. The study is based on a cau...

Enterprise systems entail complex organizational interventions. Accurately gauging the impact of any complex information system requires understanding its multidimensionality, and the development of a correspondent, standardized, validated, and robust measurement instrument. Despite the popularity and potential of enterprise systems in modern organizations, no acceptably valid and reliable ente...

In the logistics system of electronic commerce, the major difference between Taiwan and other countries is the retailing delivery (RD) system. Delivering consistently good service quality is difficult but profitable for logistics organizations. This paper explores the structure of logistic for RD service for electronic commerce. Drawing upon a sample of 135 users of retailing delivery and worki...

Conventional wisdom suggests that data quality plays a central role for compiling valid and reliable plans to make the right decisions. At the same time, it is acknowledged that planning processes are both data and knowledge intensive and characterized by the human-computer interface. However, there are limited academic investigations on how data quality and analytical capabilities simultaneous...

Background: This study provides empirical evidence of the relationships among learning organization, internal marketing, and organizational commitment. Internal marketing assists hospital administrators in improving the quality of service provided by nursing staff to their patients and allows hospitals to build a learning culture and enhance the organizational commitment of its nursing staff. M...

In both the US and the UK donor attrition rates are an increasing cause for concern. Many organizations lose up to 60% of cash donors after their first donation. In this study we delineate the factors that drive donor commitment to a cause and subsequent loyalty. A series of nine focus groups were employed to derive study hypotheses that were then tested using the technique of structural equati...

In this paper, we propose a novel image quality assessment (IQA) based on an Improved Structural SIMilarity (ISSIM) which considers the spatial distributions of image structures. The existing structural similarity (SSIM) metric, which measures structure loss based on statistical moments, i.e., the mean and variance, represents mainly the luminance change of pixels rather than describing the spa...

State-of-the-art image denoising algorithms attempt to recover natural image signals from their noisy observations, such that the statistics of the denoised image follow the statistical regularities of natural images. One aspect generally missing in these approaches is that the properties of the residual image (defined as the difference between the noisy observation and the denoised image) have...

Service quality becomes the key bottleneck of the adoption of G2B e-government services. In this context, control is an important tool for e-government service providers to direct and coordinate the service process. Based on the control theory, we develop a conceptual model to understand how different control initiatives influence the service quality of G2B e-government services. A multi-method...
