    This study proposes a revised technology acceptance model that integrates expectation confirmation theory to measure gender differences with regard to continuance online shopping intentions in Saudi Arabia. The sample consists of 650 female respondents. A structural equation model confirms model fit. Perceived enjoyment, usefulness, and subjective norms are determinants of online shopping continuance in Saudi Arabia. High and low online spenders among women in Saudi Arabia are equivalent. The structural weights are also largely equivalent, but the regression paths from perceived site quality to perceived usefulness is not invariant between high and low e-shoppers in Saudi Arabia. This research moves beyond online shopping intentions and includes factors affecting online shopping continuance. The research model explains 60% of the female respondents’ intention to continue shopping online. Online strategies cannot ignore either the direct and indirect spending differences on continuance intentions, and the model can be generalized across Saudi Arabia

    Objectives: Osteopontin (OPN) is a key extracellular matrix protein that is involved in cancer progression. The aim of thecurrent study is to investigate the relation of OPN immunostaining in endometrial carcinoma with clinicopathologicalparameters.Material and methods: Archival 71 endometrial carcinomas and 30 non-neoplastic endometrial tissues were obtained fromthe Department of Pathology at King Abdulaziz University Jeddah, Saudi Arabia. Tissue microarrays were constructed. Tissuesections were stained using anti-human OPN monoclonal antibody. Immunostaining results were recorded and analysed.Results: In non-neoplastic endometrial tissues, high (increased) OPN immunostaining was observed in 100%. In endometrialcarcinoma, high (increased) OPN immunostaining was seen in 64.8% of cases. High (increased) OPN immunostainingwas more frequent in non-neoplastic tissues than in endometrial carcinoma (p < 0.001). OPN immunostaining showed noassociation with histological type, FIGO tumour grade, tumour size, myometrial invasion, lymphovascular invasion, surgicalresection margin or lymph node metastasis. On the other hand, high (increased) OPN immunostaining was associated withbetter overall survival [Log Rank (Mantel-Cox) = 4.385, p = 0.003].Conclusions: In endometrial carcinoma, immunohistochemical staining of OPN could be a helpful tool in the predictionsurvival pattern. OPN immunostaining showed no association with most clinicopathological features. Further investigationsboth clinical and molecular are needed to explore the downstream of OPN in endometrial carcinoma

    Adapting tam and ECT: continuance intention of e-shopping in Saudi Arabia

    The objective of this study is to clarify the theoretical problem and identify factors that could explain the level of continuance intention of e-shopping in context of Saudi Arabia. The study proposes a revised technology acceptance model that integrates expectation confirmation theory to measure age differences with regard to continuance online shopping intentions. Structural equation model confirms model fit. The research findings confirm that Perceived usefulness, enjoyment, and subjective norms are determinants of online shopping continuance. The structural weights are mostly equivalent between the young and old groups, but the regression path from subjective norms to perceived usefulness is not invariant, with that relationship being stronger for the younger respondents. This research moves beyond online shopping intentions and includes factors affecting online shopping continuance. The model explains 65% of the intention to continue shopping online. The research findings suggest that online strategies cannot ignore either the direct and indirect effects on continuance intentions
