The significance of fairness in assessment is not a subject of doubt for educationalists even with fundamentally contrastive perspectives, but the study of methodological means for safeguarding this concept in educational classroom contexts has only received the scant attention of the researchers and educationalists. On this basis, this study intended to conceptualize foreign language (FL) classroom assessment fairness from EFL teachers' perspective. For this purpose and as a part of a larger enterprise, the researchers first strived for the creation and validation of a Classroom Assessment Fairness Scale (CAFS). This process was informed by the related literature and applied a critical incident technique. To verify the scale's validity and reliability, it was first expert viewed and modified accordingly; next pilot-tested on a group of 250 teachers, and finally, the amassed data were subjected to exploratory and confirmatory factorial analyses and internal consistency measures. The validated scale was taken by 120 Iranian EFL teachers. Descriptive analyses indicated that the EFL teachers were familiar with fairness principles in classroom assessment practices. They were aware of the significance of the opportunity to learn, the opportunity to demonstrate learning, the no-harm principle, the constructive classroom environment, and transparency as the constructive elements of classroom assessment practices' fairness. However, the same familiarity and awareness were not guaranteed for the score pollution component. The results further demonstrated that the teachers' gender, educational degree, teaching experience, and teaching context led to statistically significant differences among EFL teachers' attitudes to classroom assessment fairness.

The energy plays a significant role in human life and almost it is not possible to continue the life without it. This is why energy has a key role in our national and international policies and has shaped up patterns of rivalry, cooperation, conflict, violation, interaction, convergence, and divergence in the international arena and relations between countries and authorities. Therefore, interestingly the sources of energy provision, energy corridors, and consumer markets, energy trade, energy technology, and things like them increase in value. This study investigated energy resources in Iran and Middle East in library research method. In addition to have a unique geopolitical position, Iran is located in ellipse of energy and there is more than 70 percent of world resources of oil and 60 percent of world resources of gas in Iran. In addition, Iran has located in the energy corridor of north to south and east to west and all of the ways pass through this wide country. Hence, it can pump money into the country not only by selling energy, but also with transmitting of energy and accordingly, it can evolve the country economy with a correct planning and engagement with countries. <br />  <br /> 

Financial constraints are one of the influencing factors on investment decisions. Financial constraints put firms under pressure to forgo investment opportunities to finance their working capital needs. Moreover, some variables like working capital needs and liquidity of a firm are likely to affect the relationship between these two variables. Hence, this study seeks to examine the effect of short-term credit constraints on the investment of small and medium-sized enterprises (SMEs), firms with different characteristics in comparison with large-sized firms. In addition, this correlation is tested by considering the effect of mentioned moderating variables (working capital and liquidity). The sample of this study includes the firms listed in Tehran Stock Exchange from 2011 to 2018, which are considered as SMEs based on some criteria. Multivariate regression models and E-views software are used to test the research hypotheses. The results indicated that short-term credit constraints negatively affect corporate investment.  It means that constrained firms invest in fewer investment opportunities because of facing source shortages. Moreover, in companies requiring more working capital, the inverse effect of short-term credit constraints on corporate investment is stronger. Such firms suffer from financial problems and are not able to use their investment opportunities. Additionally, this hypothesis that companies with high liquidity can offset u effects of short-term financial constraints on fixed investment, is not confirmed
