This study aims to measure the efficiency and productivity change of 30 domestic construction companies from 2010 to 2018 using data envelopment analysis(DEA) and Malmquist productivity index (MI). In particular, we used the number of employees, capital stock, and non-current assets as input variables, and sales and net income as ouput variables for the analysis. The dataset used for the analysis of efficiency and productivity changes is the employee profile and financial statements for the companies from 2010 to 2018. We found that the MI of the 30 companies is greater than one since 2013. This is because many years of TEC (Technical Efficiency Change) is greater than 1, which means that the productivity index increases as the TEC increases. In addition, the MI value was less than 1, which lowered the productivity of construction firms in 2018. The results of the study may help decision makers to find effective future management plans by analyzing the internal and external factors.

The objective of this work is to perform a geometric analysis of the net present value (NPV) and Internal Rate of Return (IRR), defining analytics and in verifying the relationship between geometric properties of such functions. For this simulation, was used the values of the cash flows for each period identical and equal to US$ 200.00 cash, the initial investment US$ 1,000.00 and investments of each identical and equal to US$ 50.00 period. In addition, the discount rate and time were considered a maximum of 2 years (24 months) at a rate between 0 and 100%. The geometric analysis of the characteristics obtained from the expressions of the Net Present Value and Internal Rate of Return possible to observe that besides the analytical dependence between these quantities , the geometric relationships are relevant when studied in relation to the zero NPV and expressed a great contribution the sense of a broad vision for the administrator in the analysis of analytical variables that in uences the balance sheet of the company.

Purpose: A Phenomenological study was conducted to investigate the experiences of infertile women who had an unsuccessful in vitro fertilization(IVF) attempt and the structure of these experiences was identified in a socio-cultural context. Method: In-depth interviews were done with five participants from Nov. 1997 to Feb. 1998. Data was recorded and analyzed by Colazzi's method. Result: Significant statements were extracted from the data resulting in 4 themes and 11 concepts. The concepts were: 'lack of information', 'unable to anticipate the outcome', 'reaffirmation of need', 'financial strain', 'emotional suppression', 'change of social relationships', 'physical fatigue', 'blaming oneself or God', 'trying different ways', 'famous place shopping', and 'praying to God'. The significant themes of the participants' experiences with IVF emerged as: "uncertainty", "burden", "blaming" and "vigorous desire". Conclusion: The results indicate that the care of infertile women with an unsuccessful IVF attempt should be based on a deep understanding of their personal experiences. Also, information on alternative choices should be offered and supported.

Purpose - Our goal was to determine whether there is a relationship between actual profits' deviation from the profits expected in earnings per share's adjustment announcements and the degree of apparent earnings management in annual financial statements. Research design, data, and methodology - The samples consisted of 133 companies from ten industries. The companies were selected among those listed in the stock exchange, and their data were examined covering the two-year period from 2008 to 2010. Tests were conducted using a regression model and SPSS statistical software. Results - The findings indicate the following. There is no significantly positive relationship among the last earnings per share's adjustment forecast, the first earnings forecast per share, and earnings management. Moreover, the amount of the latest earnings per share's adjustment forecast relative to its first forecast is not associated with the companies' discretionary accruals items. Finally, the hypothesis that a relationship exists between companies' latest adjustments of their earnings per share and earnings management was tested the results indicate that there is no such relationship.

The purpose of this paper is to review the profitability of sixteen university hospitals of oriental medicine during 2007~2009. Data was collected from 16 hospitals that reveal financial statements to the public and the hospitals were classified into 7 groups. Net sales and COGS per 100 beds of the 7 groups were analyzed to measure profitability and as a percentage of net sales, the rates of personnel expenses, maintenance costs, and material costs were evaluated. The results showed that six groups had consecutively recorded net loss in medical services and differences in profitability among 7 groups were substantial. The analysis showed the profitability was significant for medium-sized hospitals. The rates of personnel expenses in net sales were above 50% in 6 groups with net loss and one group with net profit was 45%. This result indicate the rate of personnel expenses in net sales could be the main factor affecting profitability and further studies are recommended to analyze the determinants of profitability in oriental medical hospitals.

Purpose - Since Iran's economy is only now developing, and its stock market is only now emerging, we should deal with the relationship between ownership structure and conservative accounting of companies to see whether such a relationship exists in Iran's market. This study aims to investigate the relationship between ownership structure and accounting conservatism of listed companies on the Tehran Stock Exchange. Research design, data, and methodology - All listed companies on the Tehran Stock Exchange, for which the required information financial statements (balance sheet, profit and loss account) could be acquired for the period 2007-2012, were studied. A total of 123 companies from various industries was selected. Results - In order to test the hypotheses, multi variate regression (inter procedure), with their meaningful t- and f-statistics, and a Durbin-Watson autocorrelation model were used. Conclusions - The research results show that the ownership of major shareholders and ownership concentration have a negative significant relationship with accounting conservatism. Therefore, as a significant negative relationship between concentration of ownership and accounting conservatism at the 95% confidence level was found, the second hypothesis was confirmed.
