Abstract
The engines of software movement in Iran are universities and research institutions. This movement, reflected in scientific production, is a product of basic, applied and evaluation research. PH.D and master degree students can play an important role in scientific production. Student’s dissertations and scientific papers can be a channel for rendering Iran scientific products.
Indeed, universities not only transfer knowledge but also by academic researches, create knowledge and disseminate it in society. This created knowledge (Theory) must be evaluated. Therefore, in this paper, first we will discuss relationship between knowledge and theory, then offer a short viewpoint about concept of theory and building bricks of it and suggest some criteria for evaluating new theories in social science.

Abstract
The present study aimed to identify strategies for the application of pro-environmental technologies for greenhouse vegetable production in Tehran Province, Iran. It is an applied research type whose main instrument is a questionnaire. The population of the study consisted of 109 experts in Tehran Province, of which 86 experts were selected by stratified random sampling method (based on Krejcie and Morgan’s table). The questionnaire was revised with the help of the experts who had significant experience in crop protection to ensure the validity of the instrument. A pilot study was conducted on 22 experts in Alborz Province to determine the reliability of the questionnaire. Cronbach’s Alpha scores were acceptable for different sections of the questionnaire (0.71-0.82), so, the instrument was reliable. The research methodology is descriptive, and the SWOT analysis was used. First, the internal environment was analyzed to prepare a list of strengths and weaknesses in applying pro-environmental technologies, and then, a list of opportunities and threats were identified by analyzing the external environment. Some derived strategies include the development of appropriate mechanisms to control the sale and use of pesticides by removing barriers to registration, mass production, storage, handling, transport and consumption of biological agents, and reinforcement of the knowledge of greenhouse owners regarding biological control.
