The purpose of this research is to investigate the effect of organizational commitment (with three dimensions of emotional commitment, continuous commitment, and normative commitment) on knowledge management processes (KMP) in project-based organizations, considering the mediating role of employee motivation. This research has an applied purpose and a descriptive and quantitative nature, which was conducted with a survey strategy. The statistical population is managers and experts of first-class construction companies in Tehran. Data collection was done through a standard questionnaire with 58 questions and hypotheses were tested with SmartPLS. The findings showed that emotional commitment and continuous commitment have a positive effect on employee motivation in project-oriented organizations, respectively, 0.56 and 0.2. Also, employee motivation has a positive effect of 0.51 on KMP in project-oriented organizations. Therefore, employee motivation plays a mediating role in influencing the dimensions of organizational commitment to KMP. But normative commitment does not have a positive effect on employee motivation in project-oriented organizations. On the other hand, employee motivation is influenced by their commitments to the organization and will have positive effects on intellectual capital management, KM and ultimately business performance. Among research backgrounds, the effect of organizational commitment dimensions on improving KMP with the mediating role of employee motivation in project-oriented organizations has not been investigated. It is expected that the results of this research can finally provide scientific and executive solutions to improve the performance of project-oriented organizations through the improvement of these components.

The Portuguese navigation system was established in the 15th century as the first learning organization (LO) and achieved great success. The high similarity of the Portuguese navigation system to Project-Based Organizations (PBOs) inspires the development of a model for Project-Based Learning Organizations (PBLOs). This study analyzed the Portuguese navigation system and its components, based on which a model for PBLO was proposed. Multiple case studies were conducted with two PBOs in the oil and gas industries in order to validate and revise the proposed model. The data was collected from interviews with 20 individuals involved in project and knowledge management in the PBOs. A total of 615 statements made by interviewees were coded and summarized as concepts in the various components of the model. Since the qualitative approach to learning organizations has been neglected and few researches has addressed the issue of PBLOs, the result of this study presents innovative findings on the development learning organizations in project-based environments.

The construction industry in Iran is growing rapidly, resulting in adverse impacts on sustainable development and in particular the environment. In other parts of the world, to address these adverse impacts, the principles of the green building are applied. However, after interviewing the experts in the construction industry, it was concluded that the implementation of the green building practices is not going well. In this context, the question which this study is trying to address is why there is no construction project which implements the green building practices. Thus, the goal of this study is to assess the challenges and obstacles in implementing the green building practices based on experts’ opinions, executive and legislator institutions in the construction industry and present strategies to overcome the challenges. The difference between this study and the previous studies in this area in Iran, is that this study discovers the challenges and obstacles in implementing the green building practices in Iran with a qualitative approach, involves a wider level of analysis, and presents the solutions from the governmental point of view. This study employed the semi-structured interviews with the experts of the construction industry and used the open, axial, and selective coding techniques to analyze the findings. Eventually, 18 challenges are found encompassing two challenges related to the society, four challenges related to executive institutions and 12 challenges related to Legislator Institutions. Also, 19 solutions are extracted from the interviews with the experts including seven short-term solutions, two medium-term solutions and 10 long-term solutions. Among these solutions one solution is related to the society, two solutions are related to executive institutions, and 16 solutions are related to the Legislator Institutions.
