This study evaluated the relationship between cost and performance yield investment opportunities, cash and financial flexibility bank pays. For this study, a sample of 94 companies from companies that are part of corporate clients BSI was selected using random sampling technique. In addition, to measure the performance, three measures of economic value added, return on assets and return on equity were used. The study evaluated the relationship between cash and the opportunity cost efficiency as well as financial flexibility to invest in BSI over the period 2007-2012. Statistical methods used in this study were panel data regression. Four hypotheses were proposed to achieve the goals and the results showed that the opportunity cost of holding cash investments with financial flexibility and efficiency were inversely associated with financial performance.

Liquidity management in banks is a conflict between risk and return. On the one hand, the lack of liquidity, in addition to imposing heavy costs of providing resources (including borrowings from the central bank at elevated rates), may also lead banks to face with bankruptcy. On the other hand, the maintenance of excessive liquidity than needed will destroy investment opportunities and potential profitability. Therefore, for proper liquidity management, it is necessary to understand the factors affecting this sector to be able to exert control on each of the elements, and to prevent the incidence of problems or even crisis thereby optimize the bank profitability as far as possible. This study aimed to analyze the resources, expenses, and liquidity operating as the main activity parameters in Bank Shahr. During the study timeframe (2010 until the end of 2012), every 15 days was selected as the sample community, which were selected due to a 15-day trend analysis using census method and not by random sampling. The related data concerning each of the items, i.e. resources, expenses, and liquidity were collected and analyzed by linear regression based on time or periods of time. The above items were compared through analysis of the relative contribution to the total ratio and correlation analysis. The results showed that the growing trends of resources and expenses almost coincide and followed a specific trend and, in general, the growing trend of the resources was rising with a higher slope compared with those of expenses and liquidity. In addition, the growing trend of liquidity was almost identical throughout the entire period of study and no unusual trend was observed.

Nowadays with the growth of organizations and their affiliates, the importance of information systems has increased. Functional and non-functional requirements of information systems in an organization are supported. There are literally several techniques to support the functional requirements in terms of software methodologies, but support for the second set of requirements has received little attention. Software Performance Engineering (SPE) forum tries to address this issue by presenting software methodologies to support both types of requirements. In this paper, we present a formal model for the evaluation of system performance based on a pragmatic model. Because of supporting the concurrency concepts, petri net has a higher priority than queuing system. For mapping UML to colored Petri net diagram, we use an intermediate graph. The preliminary results indicate that the proposed model may save significant amount of computations.

This paper examines the effects of big Five factors including openness, conscientiousness, extraversion, agreeableness, and neuroticism on creativity and innovation among selected employees of municipality in city of Tehran, Iran.

The Journal of Creative Behavior, 44(1), 53-69.] for measuring creativity. Using a simple regression analysis, the study has detected negative and meaningful relationship between neuroticism and creativity and innovation (B = -0.229, t-value = -3.196), a positive and meaningful relationship between extraversion and creativity and innovation (B = 0.209, t-value = 3.204) and finally a positive and meaningful relationship between openness and creativity and innovation (B = 0.225, t-value = 3.717). However, the study did not confirm any relationship between agreeableness as well as conscientiousness and creativity & innovation.

This study examines the relationship between the returns of two value and growth portfolios and the return of market on 15 selected firms on Tehran Stock Exchange over the period 2008-2011. The study divides the firms into two groups in terms of the ratios of price on earning as well as price on book value into two groups of value and growth portfolios.
