Mobile information and communication technology changed how people and businesses can benefit from government public services at any time and from anyplace. The success or failure of mobile government services is becoming more dependent on satisfying the needs and the expectations of both citizens and business organizations. This paper reviews and analyses some existing empirical studies that examine m-Government acceptance in some developing countries. Then, a new integrated conceptual model for examining some important key factors that may affect m-Government acceptance in Jordan from user perspective was proposed.  An empirical test was conducted using a questionnaire to explore the effect of the following factors: Trust in mobile channel, trust in government, perceived usefulness, perceived ease of use, relative advantage, compatibility, complexity, service quality and user satisfaction on the behavioural intention to use m-Government applications. Finally, justification of the proposed integrated model and formulation of the associated hypotheses was conducted.

This paper employs a measurement of the service quality of educational Websites as perceived by students, following a conceptual model developed by Santos (2003).  Perceived service quality of educational Websites is conceptualized as dependent on the following variables—ease of use, content, reliability, privacy, and interaction. An empirical test with university students validates the overall model.  As for the individual independent variables, all of them except privacy are found to have a significant effect on perceived service quality.

Today, the increasing digitalization makes the service industry like banks provide e-banking services or online banking in order to access the competitive advantage and dedicate much market share for themselves as it has crucial role in increasing the organizational profitability and customers’ satisfaction and loyalty, the quality of e-banking services is of great importance in e-banking studies. Little attentions were given to review of literature to formulate model as a guide for empirical test. This is a research paper in progress paper discussing the interaction among the E-Banking Service Qualities, E-Customer Satisfaction, and e-Loyalty form the customers’ point of view. The reviews of literatures covers the trends in internet banking , E-service quality dimensions relating to  e-banking services, e-Service Quality Dimension Measurement in Internet Banking, Key e-service quality factors influencing e-banking success, Interaction between e-Service Quality and e-Customer Satisfaction , Interaction between e-Customer Satisfaction and e-Loyalty, Interaction among e-Banking Service Quality, e-Customer Satisfaction and e-Customer Loyalty, Influence of Personal Demographic Factors on online banking, and conceptual model is formulated from the reviewed literatures. It is a concept paper formulated a research conceptual framework, and model to show the interactions among the E-service quality, e-satisfaction, and e-loyalty among the internet banking customers. Another part of this research will empirically test the formulated hypotheses in the present research work.

Objectives. A key challenge in evaluating the impact of community-based participatory research (CBPR) is identifying what mechanisms and pathways are critical for health equity outcomes. Our purpose is to provide an empirical test of the CBPR conceptual model to address this challenge. Methods. A three-stage quantitative survey was completed: (1) 294 US CBPR projects with US federal funding were identified; (2) 200 principal investigators completed a questionnaire about project-level details; and (3) 450 community or academic partners and principal investigators completed a questionnaire about perceived contextual, process, and outcome variables. Seven in-depth qualitative case studies were conducted to explore elements of the model not captured in the survey; one is presented due to space limitations. Results. We demonstrated support for multiple mechanisms illustrated by the conceptual model using a latent structural equation model. Significant pathways were identified, showing the positive association of context with partnership structures and dynamics. Partnership structures and dynamics showed similar associations with partnership synergy and community involvement in research; both of these had positive associations with intermediate community changes and distal health outcomes. The case study complemented and extended understandings of the mechanisms of how partnerships can improve community conditions. Conclusions. The CBPR conceptual model is well suited to explain key relational and structural pathways for impact on health equity outcomes.
