The use of building regulations in architectural design has been a controversial issue for a long time. From the view point of critics, building regulations inhibit innovation, promote conservative design and are incapable of insuring design quality. From the defenders point of view, some professional mentalities of architects regarding building regulations are problematical and must be changed. The present research aims to illuminate the reasons for the above-mentioned tension between architectural design and building regulations. This is done by examining the structural match between architectural design and building regulations. Seeing from a designer point of view, the paper compares formal characteristics of building regulations with architectural design. Three general characteristics of building regulations are found in contrast to characteristics of architectural design. Building regulations are analytical in nature, while architectural design is a synthesis-oriented act. Building regulations are mainly based on a reductionist approach towards defining design problems and solutions, while innovation and originality are considered as fundamental values by most architects. And thirdly, building regulations are usually framed in a way that matches an evaluative mode of thought, while architects often have to work in a generative and predictive mode. These explain why architects from time to time feel frustrated with regulations. The paper continues to make recommendations to both architectural designers and regulators. To the designers some facts and points are stated to help them better understand the nature and performance of building regulations and guide them safely and positively use regulations in their design process. Addressing the legislators, the paper offers some recommendations to facilitate the use of building regulations in architectural design. Moving towards performance-based regulations, a broader involvement of information technology in building regulations, and production of designer-oriented guidance documents are some of these recommendations.

The present study aimed to investigate and compare the relationship between academic buoyancy, learning styles, and school bonding among students educated via the educational approaches of Mizan and public schools in Tehran. The study was descriptive-correlational. The statistical population comprised 2680 elementary-school students in Tehran in the 2018-2019 academic year. A sample of 600 was selected from public and guided discovery schools (300 students from public and 300 from Mizan guided discovery schools) based on stratified random sampling. The research tools included Martin and Marsh Academic Buoyancy Scale, Grasha-Riechmann Learning Style Survey (LSS), and Rezaei Sharif School Bonding Questionnaire (SBQ). Data were analyzed using the Pearson correlation coefficient and one-way analysis of variance (ANOVA). The results showed that the score of academic buoyancy was significantly higher among students receiving guided discovery than those receiving traditional education (p <0.05). The mean scores of avoidant and competitive learning styles were lower in students receiving guided discovery learning (p <0.05). Furthermore, the mean scores of school bonding and belief in school were higher among students receiving guided discovery than public education. (p <0.05). The study findings further highlighted the significance of considering learning styles and school bonding on academic buoyancy. It is considered a crucial step in understanding the factors affecting academic buoyancy in students.

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.

Social capital is a relatively new concept in the social sciences and is one of the most important challenges of new era in a way that based on experts’ comments, the solution for all the problems of today’s modern world is social capital. To this end, one of the problems that managers of organizations particularly; service and manufacturing organizations have faced with today is lack of trust in accurate implementation of contract specifically implied contracts. If managers tend to control the whole organization for the accurate implementation of these contracts, it would lead to extravagant costs. One proper and certain way to solve this problem is to apply elements and components of social capital in organizations. By deploying scientists’ thoughts regarding social capital, the present research attempts to analyze the evidence of social capital reduction in banking industry and test its impact along with other forms of capital on GDP of the country. Findings of this study indicate that there is a significant and reverse relation between social capital reduction in banking industry and GDP. JEL Classifications: J24, E23, D81, E58
