This paper presents an empirical investigation to study the effect of knowledge management on job satisfaction in Iranian texture industry. The proposed study of this paper designs a questionnaire and distributes it among 219 out 230 employees who work for one Iranian texture firm in province of Markazi in Iran. The study uses structural equation modeling to examine different hypotheses based on the implementation of LISREL software package. The results of our investigation indicate that knowledge management positively influences on organizational improvement, organizational learning as well as quality improvement. The results of study also indicate that while there was a negative relationship between organizational improvement and job satisfaction, quality improvement and organizational learning positively influence on job satisfaction.

Knowledge management plays an essential role on achieving business success and it is considered as intangible attests for many organizations. In fact, many people believe intangible assets are the most influential part of any firm’s investment. This paper investigates the relationships among four variables including empowering leadership, task technology fit, compatibility and knowledge management system (KMS). The study considers whether there is any positive relationship between empowering leadership and task technology fit, between empowering leadership and compatibility, between task technology fit and KMS usage and between compatibility and KMS usage. The survey selects a sample of 215 people from the regular employees as well as university professors of Islamic research center of Qom province, Iran. We have distributed 220 questionnaires and collected 160 for the investigation. The results of this survey indicate that there is a meaningful and positive relationship between empowering leadership and compatibility (0.72, t-student=4.01), a meaningful and positive relationship between empowering leadership and compatibility (0.80, t-student=4.64), a positive and meaningful relationship between task technology fit and KMS usage (0.72, t-student=3.58) and finally there is a positive and meaningful relationship between compatibility and KMS usage (0.43, t-student=2.78).

Organizational structure plays an important role on survival of any business units and it is important to understand different factors influencing it. In this paper, we present an empirical study to learn the effects of three parameters including formality, concentration and complexity on organizational performance. The proposed study of this paper is implemented for one of research-based organization located in city of Qom, Iran. There were 120 employees working for this organization and the proposed study of this paper has selected a sample of 100 people, designed, and distributed a questionnaire among them. The proposed study uses two methods of regression analysis as well as structural equation modeling to study the impacts of three variables on organizational performance. The results show that there are some positive and meaningful relationship between formality and concentration from one side and organizational performance from the other side. In addition, there is a meaningful and negative relationship between complexity and organizational performance. The results of structural equation modeling are also consistent with the results of structural equation modeling.
