The purpose of this research is to investigate the interrelationships among the three behavioural constructs of job involvement, job satisfaction and organizational commitment. Accordingly, a structural model is developed to delineate the interactions among these constructs and explore the mediating effect of job satisfaction on the relationship between job involvement and organizational commitment. A questionnaire-based survey was designed to test the aforementioned model based on a dataset of 315 employees working in twelve out of twenty six banks operating in the capital city of Jordan, Amman. The model and posited hypotheses were tested using structural equation modelling analysis. The results indicated that job involvement positively and significantly affects job satisfaction and organizational commitment. Additionally, job satisfaction proved to be positively related to organizational commitment. Furthermore, job satisfaction positively and significantly partially mediated the relationship between job involvement and organizational commitment. 展开更多

This paper presents the application of autoregressive integrated moving average (ARIMA), seasonal ARIMA (SARIMA), and Jordan-Elman artificial neural networks (ANN) models in forecasting the monthly streamflow of the Kizil River in Xinjiang, China. Two different types of monthly streamflow data (original and deseasonalized data) were used to develop time series and Jordan-Elman ANN models using previous flow conditions as predictors. The one-month-ahead forecasting performances of all models for the testing period (1998-2005) were compared using the average monthly flow data from the Kalabeili gaging station on the Kizil River. The Jordan-Elman ANN models, using previous flow conditions as inputs, resulted in no significant improvement over time series models in one-month-ahead forecasting. The results suggest that the simple time series models (ARIMA and SARIMA) can be used in one-month-ahead streamflow forecasting at the study site with a simple and explicit model structure and a model performance similar to the Jordan-Elman ANN models. 展开更多

In this paper, a statistical comparative investigation of the implementation of Concurrent Engineering (CE) in Jordanian Industry is introduced, practices of CE are reviewed, then mapped into six statistical latent. A Structural Equation Model (SEM) is developed for the implementation of CE, then the model is applied to the following Jordanian industrial sectors: chemical and cosmetics industries, engineering and electrical industries and information technology, wood and furniture industries, and construction industry. The implementation level for the six CE practices among the selected sectors is investigated;a statistical comparative analysis between the considered industrial sectors is conducted. Thereafter, a system dynamics model is developed to understand the true CE trade-offs, which is used as a validity measure to insure that the proposed statistical model and hypotheses are valid. 展开更多

Despite of the advantages of Information and Communication Technology (ICT) which makes our lives easier, faster, and more connected, the development of ICT is pushing the countries in the direction of ICT applications. The higher education is one of the sectors that try to adopt one of ICT applications through E-learning and using (Moodle) as learning management system. This paper finds out the impact of Moodle on students through examining the students’ acceptance of the system using TAM model. This study was carried out by some teaching members of the Faculty of King Abdullah II School for Information Technology at the University of Jordan during the spring semester of the academic year 2013/2014. The results of this study firm the original TAM’s findings and reveal that the faculties of students and number of previously E-learning courses have an influence on perceive ease of use and perceived usefulness while the level of the academic year and GPA have no significant influence on perceived ease of use. Even though, they have affected on perceived usefulness. Finally, the student’s skills on computer with student’s difficulty in reading from the screen affect perceived ease of use but, it has been found that they have no influence on perceived usefulness. 展开更多
