This paper examines the role of development banks in the fixed investment formation and economic growth of the country with emphasis on the facilities granted by development banks. To do this, quarterly data of the country's development banks in the period 2006-2020 and experimental tests related to the causal relationship of variables and estimating the long-run relationship between variables were used with the Granger causality test and vector autoregression method (var). The results show that the development sector facilities and total banking network facilities (except for development sector facilities) have had positive and significant effects on fixed investment formation and other banking network payment facilities except the development sector and liquidity volume have had no significant effcets. Regarding the relationship between the liquidity and total paid facilities of the banking system, with the variable of fixed investment formation, the results show that all paid facilities have had positive and significant effects and liquidity has insignificant effects on fixed investment formation. According to the results of the long-run relationship, the development sector facilities and the volume of liquidity, in the long run, have had a significant relationship with fixed investment formaton in the Iranian economy. According to the results of the short-run relationship, development sector facilities have had positive and significant impacts on fixed investment formation and investment in the economy. Therefore, it can be concluded that the development sector facilities in both the short-term and long-term have been able to have a positive and significant effect on fixed investment formation

What is clear is that judges usually judge cases based on their knowledge, experience, personality, and sentiment. Due to high pressures and stress, it may be difficult for them to carefully examine documents and evidence, which leads to more subjective judgments. Legal judgment prediction with artificial intelligence algorithms can benefit judicial bodies, legal experts, and litigants as well as judges. In this research, we are looking at predicting legal sentences in drug cases involving the purchase, possession, concealment, or transportation of illicit drugs, using machine learning methods, and the effect of sentiment and emotions in case texts on predicting the severity of whipping, fines, and imprisonment. So, the text documents of 6000 Persian drug-related cases were pre-processed and then the translation of the NRC Glossary of Emotions and sentiment was used to give each item a score for positive or negative sentiment and a score for emotion. Then machine learning methods were used for modeling. BERT, TFIDF+Adaboost, and Skipgram+LSTM+CNN methods had the highest accuracy, respectively. Also, evaluation criteria were analyzed in situations where sentiment scores, emotional scores, or both were used in the prediction process along with judicial texts. Finally, it was found that the use of sentiment and emotion scores improves the accuracy of legal judgment predictions for all three types of sentences and that sentiments have a greater impact on the accuracy of legal judgment predictions than emotions

Economic freedom or economic liberty is one of the instances of freedom which is a target intrinsically, and individuals and units make attempts to achieve. The liberalization of financial markets can have a different effect on economy. Several studies have indicated that economic liberalization has had a positive effect on developing economies by the reduction in capital expenditures, increase in profit-ability, and individuals’ investment. The present study aimed to investigate the effect of economic freedom on stock returns. The statistical population of this study is the selected countries of the Organization of the Islamic Conference (OIC) for the years 2001 to 2019, and is used in the statistical section of the Fraser Institute website and the World Bank website. In this study, the regression model of panel data was employed for data analysis. The research results show that the effect of the economic freedom variable is positive and significant on the stock price index and cash-on-cash return. At best, economic freedom can lead to increasing demand for stocks and, subsequently, raising the stock price index and cash-on-cash return. The government should provide a legal and regulatory framework to protect the rights of owners of assets and fair implementation of contracts, and facilitate access to sound money. It should also provide stable money and refrain from activities and interventions interfering in personal choices, exchanges and voluntary exchanges, and the free-dom to enter the competition in product and labour markets.

The aim of this research is to measure the quality of environmental health of recreational and natural sports swimming pools with a risk management approach in Gilan Province. The study was descriptive - cross-sectional, and three selected sites were sampled. Microbial parameters, temperature and PH were measured. Microbial tests were carried out according to national standards in the laboratory. It was used to analyze data from standard tables related to pollutants and compare them to existing data. SPSS software was used to analyze data from experiments. Two William fine quantitative methods and the risk assessment table technique were used to assess risk. The results showed that the burden of microbial contamination in the Anzali swamp was higher than other sites. In other words, the most polluted sites in Gilan Province were the Anzali wetland, the Kiasar wetland and, at the end, the eyeglass wetland, respectively. Also, the average number of total cliform and cliform, respectively 375 and 109 MPN in 100 ml of samples, and Enterococcus of the rivers 7/17 CFU in 100 ml of samples were observed. The average pH was 89/7, which is within the standard range. On the other hand, the average water temperature measured in these natural swimming pools is 4/25 degrees Celsius, which is within the standard range. It was found that the type of risk "outstanding", the level of aspect "ultimate" and the control required were "appropriate control action and the necessity of corrective action".
