The present study was an applied research in terms of purpose and a descriptive correlational survey in terms of method. Cochran's formula was used to determine sample size which was 219 employees. The statistical sample was selected using simple random sampling. A standard questionnaire was distributed among them to answer the questions. Some experts were asked to give their opinion on the face validity of the questionnaire. The reliability of the questionnaire was examined using Cronbach's alpha test. The data were analyzed using linear regression test. The results indicated that management information system affects employees’ performance, decision-making, and reducing time of activities in Tehran Province Water and Wastewater Company in district 5. Friedman test results to rank the impact of management information system on employees’ performance indicated that performance of employees is the first priority in terms of effectiveness.

Clarification of the legal and religious status of property ownership rights and paving the way for elimination of defects and completing existing rules and therefore, expanding economic security as well as determining and explaining the limits of expropriation by religious legitimate government and religious statement of permission of such an action from the Islamic State and clearing objectives which cause political system ignore ownership of individuals and expropriation of them are among thing which are required to be reviewed in the Iranian legal system because article 1 of the urban land law approved in 1987 states that: “this law was passed in order to regulate and formulate issues related to land and increased supply and reforming and stabilizing its price as one of the major factors of production and public and social welfare and creating more accurate and wider backgrounds to maintain and exploit the lands as well as allowing for the implementation of Article 31 and meeting the goals set forth in Articles 43, 45 and 47 of constitution of the Islamic Republic of Iran to provide housing and public facilities”. Nevertheless, the author of this article is trying to answer this question that what are legal basis and purposes of expropriation and limiting urban lands ownership? To answer this crucial question; we will initially explain the concept of expropriation and then, we will review principles and legal reasons for permission for this action by the government and then, we will explain the purposes of expropriation and limiting land ownership. Legal Principles of expropriation and limitation of ownership of urban lands by the government are cases such as special powers of the supreme Leader, private owners being bound to observe the legal criteria, preventing injurious to others in the exercise of the ownership right and the necessity of observing Islamic standards in financial and economic affairs.

This study was performed to identify factors affecting the entrepreneurial university. In order to achieve this goal, a sample of 173 faculty members (academic rank of associate professor or higher) in academic year of 2015-2016 was selected using the using relative stratified sampling and Cochran’s formula. In this study, given the purpose and nature of research, for analysis of the data, exploratory and confirmatory factor analyses were used. The results of in-depth interviews and semi-structured and targeted interview with 14 qualified university professors led to the initial questionnaire developed by the researchers at 5-point Likert scale with 50 items; upon exploratory analysis, 9 items were excluded due to extraction value of commonality smaller than 0.5. Content validity of the questionnaire was approved by accredited academic experts. To assess the construct validity, convergent and divergent validity criteria were used. The results of factor loadings of each item showed that all items had factor loading of over 0.4 and average extracted variance of over 0.5, thus convergent validity of the variables was confirmed. In addition, the values ​​of the square root of the average variance extracted (AVE) was highest, indicating the validity of divergent validity of the variables. Composite reliability and validity of the questionnaire for all variables showed high levels of 0.7. Results showed that the size and components affecting establishment of entrepreneurial university included internal factors (capabilities, management and leadership, structure, prospects, financial resources and research, cultural and education policies) and external factors (interaction with environment and internationalization of the university). Finally, test of the model using t-test showed that the size and the identified factors had a positive and significant impact on the entrepreneurial university.

During a very long period of time, civil engineers have been the only ones to be designated as the experts for underground space, while the planners and architects were the ones of the development at the surface. Cities worldwide tend to overlook an invaluable asset that lies beneath their surfaces. Most cities and urban regions are unaware of the benefits underground space use has to offer, both for climate inflicted and spatial constraints: In many cities, infrastructure development is being outpaced by population Growth. Climate change effects are requiring radical new approaches in terms of coping with for example excessive rainfall. The available space at the surface is rapidly being used up and the biggest danger is that built-up spaces are taking over the public green spaces of cities thereby threatening livability and quality of life. Urban underground space forms a societal asset, which is often unappreciated and underestimated in terms of the role it can play within dynamic city environments and associated challenges. The world-wide trend of increased urbanization creates problems for expanding and newly-developing cities alike. Population increase leads to an increased demand for reliable infrastructure, nowadays combined with a need for increased energy efficiency and a higher environmental awareness of the public. The use of underground space can help cities meet these increased demands while remaining compact, or find the space needed to include new functions in an existing city landscape. Use of Urban Underground Space (UUS) has been growing significantly in the world’s biggest and wealthiest cities. UUS has been long acknowledged to be important to the urban development agenda: sustainability, resilience, livability, and creating a better urban environment in particular.
