Colourants on the wall paintings of a mediӕval fortress at the mount Sofeh in Isfahan, central Iran
No full textColourants on the twelfth century wall paintings excavated at the fortress located on the mount Sofeh in Isfahan, central Iran, were analysed using micro X-ray fluorescence (μ-XRF), micro Raman spectroscopy (μ-Raman) and high-performance liquid chromatography coupled to electrospray ionization quadropole time-of-flight (HPLC-ESI-Q-TOF). The results of the analyses showed that gypsum, atacamite, carbon black, orpiment and ultramarine blue were used as white, green, black, yellow and blue pigments, respectively. Moreover, three red colourants including red lead, red vermilion and madder red were identified in the wall paintings. Furthermore, possible sources for the colourants are discussed
Measuring Productivity of Private Companies on the Iran Stock Exchange
No full textThrough the calculation and analysis of the productivity indices of the total production elements, it is possible to determine the performance of the private industrial sectors in terms of the optimized application of the production resources. Therefore, these days, productivity is considered necessary for the economic growth and improvement of lifestyle and welfare of a country. Our country’s success depends on technical know-how, creativity of the employees, applying new scientific methods for management and innovation, all of which will be manifested in form of an increased productivity. We can determine the performance of private sectors for optimising production resources through analysis and calculation of index factor from factor productivity. The purpose of this study is to measure the productivity of companies and selected industries on the Tehran Stock Exchange. This research measures total, average and final productivity of various industrial activities over the period 2001–2009. To study and evaluate total productivity of the industries, a Cobb–Douglas production function is used. The results indicate that the overall productivity is 2.12. In fact, the per unit cost to income ratio of the private firms increases, productivity increases 2.12 units; final productivity of capital, labour force and intermediate goods are 0.60, 4.94 and 0.51, respectively. Key words: performance measurement,productivity measurement , total factor productivity (TFP), Cobb–Douglas function,
Designing and Explaining the Structural Model of Financial Agility of the Supply Chain Process of Commercial Companies in Iran with a Combined Approach
No full textThe population of participants in this study included academic and industry experts that the number of samples was selected based on the method of snowball sampling to people. In data analysis, first, codes and components of financial agility were extracted from the interviews and developed in the form of a conceptual data model of the foundation. The central category was financial agility, which was presented in 3 dimensions, as well as causal, contextual, intervening conditions, strategies and results, and the final model was presented. Then, using Delphi analysis method, design questionnaire and initial model were presented by experts in correction, approval and financial streamlining model of supply chain process of commercial companies in Iran. Second-order factor analysis and Structural Equation Modeling (SEM) have been used. In general, the research findings of this section also showed that there is a significant relationship between causal conditions and the central category. the results of this study, the main categories of the developed model include intra-organizational, technological and human factors of financial agility of the supply chain process of commercial companies in Iran, based on which the expected consequences of the financial agility model can be achieved

No full textStudying the effect of assets return rate on stock price of the companies accepted in Tehran stock exchange
No full textOne of the criteria to evaluate management ability of a company to gain return is assets return rate, with regard to existing resources. Management is expected to use the current assets so that the maximum return is gained.
The present study aims at investigating assets return rate impact on stock prices of the companies accepted in Tehran stock exchange. In this research, assets return rate is considered as independent variable, and stock price as dependent variable, and company size, company age, and beta coefficient as control variables from 2001 to 2010. Research method is correlation in terms of hypothesis testing, and through multi-variable regression statistic analysis has been done. The research findings indicate strong impact and relationship between independent and dependent variables, and the research hypothesis has been accepted
