Web-based systems are increasingly being used for decision support applications. However, few empirical studies examine the impact of web-based decision support systems (DSS). This experimental research looks at the various factors that impact decision-making in web-based DSS. Using a structural equation modeling (SEM) approach, the analysis reveals that information quality and system quality a...

Prevalent approaches to software reliability model-ing are black-box based, i.e., the the software system is considered as a whole and only its interactions with the outside world are modeled without looking into its internal structure. However, with the advancement and widespread use of object oriented systems design and development, the use of component-based software development is on the ri...

Uncovering unobserved heterogeneity is a requirement to obtain valid results when using the structural equation modeling (SEM) method with empirical data. Conventional segmentation methods usually fail in SEM since they account for the observations but not the latent variables and their relationships in the structural model. This research introduces a new segmentation approach to variance-based...

Identifying individual and social factors affecting MS patients’ quality of life can play a significant role in planning, treatment process and modifying their lifestyle. Thus, this study proposed a structural model explaining MS patients’ quality of life based on health-promoting lifestyle with the mediating role of psychological capital. The study had a correlational design.  The population o...

background: increasing attention to the concept of polycystic ovary syndrome (pcos) health-related quality of life has led to the development of tool that aims to measure this concept. objective: the purpose of this study was to conduct a systematic review of psychometric properties of the pcos health-related quality of life questionnaire. materials and methods: a search of database (pubmed, ps...

Structural genomics projects are providing large quantities of new 3D structural data for proteins. To monitor the quality of these data, we have developed the protein structure validation software suite (PSVS), for assessment of protein structures generated by NMR or X-ray crystallographic methods. PSVS is broadly applicable for structure quality assessment in structural biology projects. The ...

Objective methods for assessing perceptual image quality traditionally attempt to quantify the visibility of errors (differences) between a distorted image and a reference image using a variety of known properties of the human visual system. Under the assumption that human visual perception is highly adapted for extracting structural information from a scene, we introduce an alternative complem...

the increasing emphasis on supply chain management (scm) has led researchers to rethink models, constructs, and frameworks for quality management (qm) that have been developed for the field of operations management. in this paper, within the framework of a structural model we investigate how these two supply chain management-related quality practices (customer focus and supplier quality managem...
