Human resource management practices and organizational performance: The mediation of knowledge management and the moderation of competitive strategies in Jordanian service organizations

This study examined the mediating influence of knowledge management on human resource management (HRM) practices and organizational performance (OP), and the moderating role of competitive strategies on the relationship between knowledge management (KM) and organizational performance. Two-hundred and sixty service organizations in Jordan participated in the survey. Multiple regression and hierarchical multiple regressions were used to test the hypotheses. Results indicated that only three dimensions of HRM practices (i.e. staffing, training and development, and job security) had positive influence on OP. Factor analysis revealed three dimensions of KM: technical, cultural, and human. The results further showed that specific HRM practices were significantly associated with different KM dimensions. Performance appraisal had a positive influence on technical KM, while staffing, performance appraisal, and job security were positively associated with cultural KM. Staffing, training and development, and employee participation and involvement were found to enhance human KM. In addition, different dimensions of KM were found to mediate between different types of HRM practices and OP. Technical KM mediated the relationship between staffing, and training and development and OP, while cultural KM mediated the relationship between staffing and job security, and OP. On the other hand, human KM mediated the relationship between staffing, training and development, and job security, and OP. Finally, competitive strategies interacted with human KM in predicting OP. This study offers several recommendations on how to improve the performance of the service sector in Jordan, discusses limitations of the study, and outlines suggestions for future research

An Analytical Study of the Reality of Ensuring the Quality of Education in Jordanian Universities

The purpose of this study was to find out to what extend application of the concepts of quality ensures of education in the formal Jordanian universities, and what are monitoring the strengths and weaknesses in the education system from the perspective of the entrance of ensure quality, and then sagest the factors that enhance the strengths and overcome the weaknesses. The study sample consisted of (63) Dean who work in official Jordanian universities. A questionnaire which developed by Abo varh (2004), was used ,which consisting of (94) items distributed on five areas each one covering a variable of the study. The study results showed that the quality assurance system in Jordanian universities is still below the expected level. Also the reality of ensuring quality of inputs is still not enough, and that there is decline significantly in the level of quality ensures universities education, as interest in universities to ensure quality outcomes and follow-up of its graduates in the labor market is still low interest.

Electromagnetic Energy Harvesting

The advent of rectenna systems has opened the door for many applications, with the main goal of harvesting electromagnetic waves. Many designs have been presented to provide a high conversion efficiency. Some works have been focused on the antenna part, where a high-efficient electromagnetic wave to AC conversion can be achieved. Other works focused on the rectification part, where a high-efficient AC to DC conversion is desired. Even though each part can separately achieve a high conversion efficiency, connecting both parts can dramatically deteriorate the achieved efficiency. In general, increasing the accuracy of components' characterization leads to a high-performance design. Since the main component in the rectifying circuit is the diode, an accurate model for a nonlinear system is required for efficient use of computer-aided design (CAD) technology. Currently, many models of nonlinear devices consist of basic electric elements such as capacitors, inductors, and resistors. However, building such models needs complex measurement procedures to extract the required parameters precisely. Furthermore, it may take a year to develop and validate an accurate model. Considering challenges associated with traditional approaches of modeling, an accurate and relatively easy method based on X-Parameters to model nonlinear devices has been presented. X-Parameters can be measured at different frequencies and at different power levels and stored in one file. The availability of all information in one file enables us to characterize the systems that operate under unstable conditions, such as the rectenna circuits that are used for energy harvesting. To accurately simulate a rectenna circuit, we presented a simulation methodology that calls for modeling the antenna part as a circuit that is fully independent in its characteristics from the remaining parts of the rectenna system. This can be accomplished by using Thevenin’s theorem. According to Thevenin’s theorem, a linear circuit can be replaced with an equivalent circuit consisting of an independent voltage source in series with an impedance. The Thevenin’s equivalent circuit provides all the required information about the antenna. It is important to emphasize that the equivalent circuit of the antenna obtained using Thevenin theory is not affected by the rectenna circuit that connects the antenna to the load. Antennas that can be used both as flat and as curved (conformal antennas) are becoming increasingly attractive antennas because of their wide range of applications. The microstrip patch antenna is one of the most widely used antennas, however, it has a high sensitivity to bending. An antenna with a lower sensitivity to bending is required to avoid the effect of bending on antennas. The metasurface antenna is one of the best candidates to overcome the problem of the antenna's sensitivity to bending. To construct a metasurface, an ensemble of periodic resonators is structured to operate as an effective electromagnetic radiator. In this thesis, we explored the impact of bending on metasurface antennas and microstrip patch antenna arrays

Arab Women and Political Development

Although many measures have been taken by the majority of Arab countries to enhance women’s representation in decision-making positions, women’s participation in public life and positions of power have not been achieved the desired level. The Arab region ranks the lowest in the world in terms of women’s participation in parliaments. The objective of this paper is to examine the Political participation of women in the Arab countries and identify different challenges that impede Arab women participation in politics and decision making. Challenges include: cultural factors, the stereotyped image of women, women\u27s low self-confidence, lack of coordination among women\u27s organizations, effectiveness/efficiency of women empowerment programs, shortcomings in the institutional and legal frameworks, practices of political parties and election process, skepticism about the Agenda for Women empowerment, the process of development of Women empowerment strategies. Thus, challenges facing women in politics are immense. They require the consolidation of all efforts with great belief in women’s capabilities as human beings who are able to lead and shoulder the responsibility in the building of their nations

واقع تدريس علوم الإعلام و الاتصال في الجامعات الأردنية الحكومية

This research aims to shed light on the problem of teaching the science of information and communication in the Jordanian public universities ,since there is only one out of ten public universities teaches media and communication science. Especially in light of the increasing need of Jordanian society and institutions for more qualified scientific staff to face the latest developments and media and communication developments represented in the use of the Internet and social media. This is what required decision makers in higher education obliging Jordanian universities to teach media and communication culture as a compulsory subject for undergraduate students. The results showed that all Jordanian public universities except Yarmouk University do not teach media and communication sciences. It was found that there are many views among Jordanian academics in Jordanian universities on the importance of media and communication sciences; it has become clear that: the independence of the media and communication sciences had become a necessity

Inference and optimal design for the k-level step-stress accelerated life test based on progressive Type-I interval censored power Rayleigh data

In this paper, a new generalization of the one parameter Rayleigh distribution called the Power Rayleigh (PRD) was employed to model the life of the tested units in the step-stress accelerated life test. Under progressive Type-I interval censored data, the cumulative exposure distribution was considered to formulate the life model, assuming the scale parameter of PRD has the inverse power function at each stress level. Point estimates of the model parameters were obtained via the maximum likelihood estimation method, while interval estimates were obtained using the asymptotic normality of the derived estimators and the bootstrap resampling method. An extensive simulation study of $k = 4$ levels of stress in different combinations of the life test under different progressive censoring schemes was conducted to investigate the performance of the obtained point and interval estimates. Simulation results indicated that point estimates of the model parameters are closest to their initial true values and have relatively small mean squared errors. Accordingly, the interval estimates have small lengths and their coverage probabilities are almost convergent to the 95% significance level. Based on the Fisher information matrix, the D-optimality and the A-optimality criteria are implemented to determine the optimal design of the life test by obtaining the optimum inspection times and optimum stress levels that improve the estimation procedures and give more efficient estimates of the model parameters. Finally, the developed inferential procedures were also applied to a real dataset
