This paper investigates the role of corporate disclosure policy on risk assessment and market value on selected firms from Tehran Stock Exchange over the period 2004-2012. The study considers four risk namely; business risk, cash flow risk, financial risk and systemic risk. Using regression analysis with panel data under fixed effect, the study shows that there was a meaningful relationship between two risks, business risk and systematic risk, and market value before and after corporate disclosure. In other words, after corporate disclosure, the relationship between risk and market value becomes stronger.

This paper investigates the role of exports in the regional markets on the performance of supply chain. The study first determines critical variables affecting exports for entering into the regional markets and then measures the effects of these variables on the effectiveness of supply chain performance. The study uses two questionnaires, one for measuring the effects of various factors on export development and the other for measuring supply chain performance in Likert scale. Cronbach alpha for the mentioned questionnaires were calculated as 0.84 and 0.78, respectively. The population of the survey includes all small and medium enterprises active in city of Tehran, Iran and the study selects a sample of 250 people as a sample size. Using factor analysis, the study has determined seven factors including product development, government support, strategic orientation, customer satisfaction, competitive pressures, organizational capability and distribution strategies for entry into regional markets. In addition, the implementation of structural equation modeling has disclosed that product development and distribution strategies maintained the highest impact on export activities.

This paper investigates the relationship between emotional intelligence, organizational communications and organizational citizenship behavior (OCB) for a case study of Islamic Azad University, Gorgan Branch, and Sama Institution in Iran. Statistical population includes all heads and assistants and employees of Islamic Azad University and Sama Institution in city of Gorgan, Iran as 300 people.

Efficiency is one of the fundamental concepts in any organization including ministry of education of Iran. Teachers and counselors are the main assets of this organization and education plays a key role in achieving the organization & apos; s goals. In-service training is a technique for improving the quality and effectiveness of the advisors. This paper presents a study on the effect of in-service training on advisors’ effectiveness through psychological empowerment. The study uses a questionnaire developed by Spreitzer (1995) [Spreitzer, G. M. (1995). Psychological empowerment in the workplace: Dimensions, measurement, and validation. Academy of management Journal, 38(5), 1442-1465.] to examine the effects of five variables; namely self- efficacy, self-determination, impact, meaningfulness and trust. Using structural equation modeling, the study has determined that all five psychological empowerment components had positive and meaningful effects on in-service training. In addition, in-service training maintained positive and meaningful impacts on all components on psychological empowerment. Moreover, in-service training positively influenced on psychological empowerment.

This paper presents an empirical investigation on user’s satisfaction based on the expectation disconfirmation paradigm theory. The study selects a sample of 332 people from 2449 graduate students who were enrolled at the Birjand University. The study uses a questionnaire developed by Isac and Rusu (2014) [Isac, F. L., & Rusu, S. (2014). Theories of user’s satisfaction and the operationalization of the expectation disconfirmation paradigm. Economic series, university of Targu, 2 (1), 82-88.]. Using path analysis, the study has determined that perceived usefulness and personal experience had the highest impact on users’ satisfaction in electronic library usage. In addition, there was a negative relationship between user interface and users’ satisfaction.

A convenient, highly efficient and time economic method has been described for the chemo- and regioselective synthesis of 5-aryloyl-1,3,7,9-tetraalkyl-2,8-dithioxo-2,3,8,9-tetrahydro-1H-pyrano[2,3-d:6,5-dˊ]dipyrimidine-4,6(5H,7H)-diones derivatives by one-pot two-component reaction of 1,3-diethyl-2-thiobarbituric acid or 1,3-dimethyl-2-thiobarbituric acid with substituted arylglyoxalmonohydrates using commercially available zirconium (IV) oxydichloride octahydrate (ZrOCl2.8H2O) as green Lewis acid catalyst. This method is associated with some attractive characteristics such as good selectivity, very short reaction time, high yield of products, cleaner reaction profile, no harmful by-product, cheap and environmental benign catalyst, simple experimental and work-up procedure. This procedure does not require solvent separation and purification steps such as column chromatography.

A four-component reaction of phenylhydrazines, ethyl acetoacetate, aldehydes and β-naphthol has been achieved in the presence of FeCl3/SiO2 nanoparticles as a highly effective heterogeneous catalyst to produce 2-aryl-5-methyl-2,3-dihydro-1H-3-pyrazolones in good to excellent yields, short reaction times, mild reaction conditions and the employment of a cost-effective catalyst.
