The present study is an applied developmental study and from the point of view of data collection is a qualitative one. The strategy applied in this study is the grounded theory as a systematic and qualitative approach toward creating a hypothesis. The main aim the present study follows is to design a model for the pathology of running public policies in Iran. The data was collected through face to face, profound 60 to 90 minute interviews with 20 of prominent policy makers, executives and professors asking questions on challenges of running public policies. Sampling was conducted theoretically. Initially, a set of basic concepts were recollected via coding process and categories were extracted from them. Later, in axial coding stage, the relationship between these categories was determined through coding paradigm. Then, in the selective coding stage, each part of the model was explained. The advantage of this study over other works of research conducted on the pathology of running public policies is presenting a comprehensive and practical model attempting to consider all parameters affecting an unsuccessful public policy. The present study tries to demonstrate a holistic view and identify the challenges in public policy environment, challenges of the policy in public environment, and challenges of running a public policy ending in the failure of a public policy in order to elaborate on the outcomes of a failed policy.

The general purpose this study aims to reach is to investigate the relationship between clerk’s job promotion and improvement in performance process in branches of Melli Bank in Bonab. In order to do so, studies, papers and books published in the field were examined to find proper framework for the study. Thus, the model used by Nekooyi Moghadam et.al. (2014) was taken for job promotion and the model used by Moghimi was utilized for improvement of performance. Moghimi’s model had six dimensions of credibility, attitude, work quality, innovation, cooperation and security. In this regard, one main and six secondary hypotheses were compiled. Statistical population of the study included all 67 clerks in branches of Melli Bank in Bonab. The data for the study were collected through two questionnaires of job promotion and performance. The reliability and validity of the questionnaires were approved by experts and then they were distributed among subjects. In order to analyze the data collected from questionnaires, descriptive and inferential statistics were utilized. In order to classify, summarize and interpret the data, descriptive statistics were used. Spearman and Regression tests were used to test research hypotheses. Results from these tests have approved all research hypotheses and demonstrated that there is a significant relationship between job promotion and improvement of performance in branches of Melli Bank in Bonab.

The purpose of this study, is create a challenge and discussion concerning the existence of information about the Bitcoin price and return, which suggests the relationship of information and the strong performance it. The information trends are available at different time periods and the summary data related to the statistical descriptions for the price and return index are also discussed. In this paper we show a significant correlation between the price trend and return in the Bitcoin that has been confirmed by various statistical methodology. Using statistical tests and reviewing trends and relationships between the variables, planning can be done to invest in it and its performance or inefficiency can be tested. The results of this research shows a significant and positive relationship between the price and return of Bitcoin.

Sustainable supply chain has become an integral part of the corporate strategy. In this paper, a real case study of the natural gas supply chain has been investigated. Using concepts related to natural gas industry and the relations among the compo-nents of gas and oil wells, refineries, storage tanks, dispatching, transmission and distribution network, a seven-level supply chain has been introduced and present-ed schematically. The aim of this paper is to optimize a case study using a fuzzy goal-programming multi-period model considering environmental and economic costs and revenue as fuzzy goals and maximize the total degree of satisfaction of goals as objective function. A small-sized problem was solved using GAMS 23.2.1 software and sensitivity analysis was conducted on its parameters. To the best of our knowledge, this is the first study that presents a fuzzy goal program-ming model for the optimization of sustainable natural gas supply chain by focus-ing on the environmental and economic costs and total revenue of gas products and the other main contribution of this research is focused to the developing of the mentioned model.

The Time Value of Money is a important concept in Financial Management. The Time Value of Money includes the concepts of future value and discounted value or present value. In the present article, the basic notions and illustrate with their application in the field of investment which is presented in the mathematical terms in form of theorems and we also presented the applications of some well known problems with the proof such as mortagage loan problem, investment in bond and an individual who plans to retire in certain years who plan for invest-ment for its future life. We also presented the application of calculus that is limit, derivative and integration in financial management.

Performance appraisal is a process which help shareholders make informed and optimal investment decisions. In recent decades, a long stream of research has devoted particular attention to the importance and impact of financial decisions on firm performance and firm value. The present study thus is primarily concerned with investigating the association between free cash flow and institutional ownership and long-term performance of the firms listed on the Tehran Stock Exchange over the period of 2012-2016. Moreover, firm size, financial leverage and sale grows serve as the control variables of the research. A number of 89 firms listed on the Tehran Stock Exchange were selected, and then the research hypotheses were tested using multivariate regression model based on panel data. The results reveal that firm long-term performance is not significantly correlated with free cash flow, yet it has a significant relationship with institutional ownership.

Since the seismic behavior of the earth’s energy (which follows from the power law distribution) can be similarly seen in the energy realized by the stock markets, in this paper we consider a statistical study for comparing the financial crises and the earthquakes. For this end, the TP statistic, proposed by Pisarenko and et al. (2004), is employed for estimating the critical point or the lower threshold, i.e. the point beyond that the market energy follows from the power law (Pareto) distribution. The results confirm the deviation of the energy from the Pareto distribution in the high quantiles of the energy data. The upper threshold that the energy's distribution is changed from the Pareto to another distribution is also estimated by TP statistic. A simulation study is employed for checking out the statistical behavior of the estimated thresholds. Finally, the magnitude of the financial earthquakes is studied. The results indicate that the domestic and the international events have caused the financial earthquakes in Tehran Stock Exchange. Also, the positive relation between the daily energy released and the daily magnitude of the shocks that was connected by Gutenberg and Richter (1956) is confirmed.

Supply chain integration represents the extent based on which a producer strategically cooperates with its supply chain partners and collaboratively manages inter-organizational and intra-organizational processes. The current research has been conducted to examine the effect of supply chain integration on operational efficiency and value creation. In order to do this, Annan’s et al. (2016) standard questionnaire was used to measure the research variables. The research method was descriptive correlational. In order to answer the research questions and investigate the research hypotheses, structural equations and path analysis by means of the partial least squares method (PLS) were used with Smart-PLS software. The obtained results indicate that there is a positive and significant relationship between the inter-firm networking resources and dysfunctional competitions on the supply-chain integration. The results also approve the positive and significant effect of supply chain integration on customer value creation and the company’s operational efficiency.
