This paper aims to compute the Malmquist Index of Islamic and conventional banks to compare their performance in the sample period of 2005-2009. Islamic banks have been showing tremendous growth throughout the world in recent past. Their progress is exceptional in Islamic countries on account of patronization for religious reasons. There existed vacuum in research of their productivity change over the years.

This study tries to apply the Malmquist Index. The Malmquist Total Factor Productivity Index has been further divided into Efficiency Change Index, Technological Change Index, Pure Efficiency Change Index and Scale Efficiency Change Index to obtain an insight about the reasons for the change in productivity.

Results indicate that the productivity of Islamic banks decreased in 2007 but it increased in 2008 to 2009. Islamic banks had higher productivity growth from 2005 to 2006, but they experienced lower growth in subsequent years as compared to their conventional counterparts.

This study aims to examine the effect of job stress on perceived organizational support (POS) and organizational commitment in hospitals in Amman, Jordan. It also investigated the mediating role of POS on the relationship between job stress and organizational commitment.

The study used a cross-sectional, quantitative survey design to collect data from 500 employees in six hospitals in Amman, Jordan. An Arabic version of a reliable and valid measurement instrument was used. A convenience sample was selected from employees in the targeted hospitals. Mediating effect was tested using the approach proposed by Baron and Kenny (1986). Validity and reliability tests were applied, and regression analyses were used to test the study hypotheses.

The results revealed a significant negative effect of job stress on POS and organizational commitment. The results also indicated full negative mediating effect of POS on the relationship between job stress and organizational commitment.

This research promotes hospitals to implement strategies that reduce employees’ job stress, increase levels of POS among employees working at hospitals, which, in turn, will enhance employees’ commitment to their hospitals.

This study is one of the first to investigate the proposed effects in Jordan in particular, and the Middle East in general. In addition, it contributes to the literature by examining the mediating effect of POS on the relationship between job stress and organizational commitment. Recommendations are provided to practitioners in hospitals based on the study results.
