Background: Organizational politics within organizations, like the power around the manager, is broad and widespread, and managers consider political behavior as a part of organizational life that is inevitable, and on the other hand, the impact of ethics on social and especially political behaviors is undeniable. Therefore, the purpose of this study was to design and validate organizational policy indicators based on political ethics. Method: The method of the present study was integrated (qualitative and quantitative) and in terms of purpose was applied research. The qualitative section consisted of experts with experience in the field of political behavior who interviewed 11 people using purposive sampling. The texts of the interviews were also analyzed by coding method. In the quantitative part, the statistical population was the heads and experts of the Ministry of Interior (101 people). The sample size was selected based on Morgan and Krejcie table of 80 people by random sampling method. The research instrument was a completed questionnaire with 3 dimensions, 10 components and 99 indicators, the reliability of which was obtained by Cronbach's alpha test of 0.91. Structural equations with Smart Pls software were used to analyze the data. Results: The results showed that the organizational, personal and job dimensions had (0.57, 0.44, 0.37) direction coefficient in the organizational policy model based on political ethics, respectively, and the research variables could be 0.66, the perception variable. Predict organizational policy based on political ethics. Also, the overall fit of the model was evaluated at a very high level (GOF = 0.59). Conclusion: The model of perception of organizational policy indicators based on political ethics with 3 dimensions and 10 components has a good fit and can be considered as a suitable model of political behavior in public and private organizations in Iran.

In this paper, we present an efficient and accurate method for calculating the Black-Scholes differential equations and solve the Black-Scholes equations using Jacoby and Airfoil orthogonal bases, with the collocation method. The Black-Scholes equation is a partial differential equation, which describes the price of choice in terms of time and the collocation method is a method of deter-mining coefficients. Then we show the computational results and examine the performance of the method for the two options, the price of basic assets and its issues. These results show that the Jacoby method is more efficient in solving the Black Scholes equation, and the method error is less and the convergence rate is higher. In this paper, by applying numerical methods to the desired equation, nonlinear devices can be solved by nonlinear solution methods, such as Newton's iterative method. The existence, uniqueness of the solution, and convergence of the methods are examined, and we will show in an example that by repeating then |u n+1-u n |/|u n | <ε can be reached and this indicates the accuracy of the response to these methods.

Every company should think about producing new goods, the production of alternative goods is necessary in order to stabilize the level of sales or new sales; Customers also want new products, and if the company neglects to do so, competitors will certainly do so. Therefore, the present article seeks to provide a model appropriate to the conditions of gas refining companies for product development. In this study, the qualitative research method has been used as a grand theory; Using theoretical sampling and theoretical saturation, 20 experts of gas refining companies (Parsian, South Pars, Fajr Jam) were interviewed. Based on the basic theory, the data were analyzed in three stages of coding (open, axial and selective) using MAXQDA software. In the open coding phase, the data were labeled conceptually and then those that were common to each other were named into a category; the obtained categories were 43 categories. In the central coding stage, logical relationships were found between the categories and the obtained categories were included in the open coding under more general categories; finally, in the selective coding stage, all categories were summarized in one main category. The main category of the research was named "Interfering factors in new product development". The final result of this research, according to the researcher's attention and reflection on the details of the process of each of the three refining companies, is to provide an existing common model for all three companies and also to provide a common desired model for all three companies.
