One of the factors influencing these price jumps is the speculative behavior of banks in the housing market; The purpose of this article is to investigate the effect of commercial behavior of banks, including commercial, specialized, privatized and private, on housing prices in 22 districts of Tehran. Therefore, the necessary estimates have been made by a data panel model during the period 1392 to 1398 and using monthly battery variables.The behavior of banks in the model is examined using the variables of surplus deposits, banks' debt to the central bank and non-current facilities. The overall results show that the speculative performance of non-governmental banks on housing prices is much higher than that of state-owned banks. The results of the effect of the model variables show that the elasticity of housing prices to the surplus of deposits in the privatized and private banks have the highest coefficient, respectively. The highest elasticity of housing prices to the debt of banks to the central bank is related to specialized banks, which, of course, the high ranking of specialized banks due to the defined duties of this type of banks, which is not naturally comparable to other banks; But private and privatized banks are next. ; But private and privatized banks are next. The elasticity of housing prices to non-current facilities in commercial and specialized banks has the highest rank, and private and privatized banks are in the next ranks.

The stock price index is the overall result of capital market activity in the real sector of the economy; but its sharp decrease or increase, unrelated to production, is due to speculative performance. The purpose of this article is to investigate the impact of banks' commercialization, including commercial, specialized, privatized and private, on the stock price index. Estimates have been made using a data panel model during the period 1392 to 1398. Banks' behavior has been examined using the variables of deposit surplus, banks' debt to the central bank and non-current facilities. The results show that the speculative performance of non-governmental banks on the stock market index is much higher than state-owned banks. Regarding the effect of model variables, the elasticity of the stock price index to surplus deposits in privatized banks ranked first, in private banks ranked second, commercial banks ranked third and specialized banks ranked last. The elasticity of the stock index to the debt of banks to the central bank was significant only for the debt of private banks, and the elasticity of the index in other banking groups to the central bank was not significant. The elasticity of the stock index to non-current facilities in specialized banks was ranked first. The amount of this elasticity in private, privatized and commercial banks was almost equal.

Abstract Cancer is one of the serious health problems in today's societies and is one of the leading causes of death in developing countries. Due to the fact that cancer patients suffer from many problems, including digestive problems. The aim of this study was to predict the biological indicators of stress based on emotional regulation and rumination in patients with gastrointestinal cancer. In terms of research method, this research was a descriptive-correlational research. The statistical population of this study consisted of all patients with gastrointestinal cancer who referred to hospitals in Tehran in 1400. The sample size was obtained based on the formula 50+ k5. A total of 250 patients in the population were selected by available and voluntary sampling. Data in this study were obtained using Nolen and Hooksma rumination questionnaire, cognitive emotion regulation questionnaire, and biological indicators of stress. In this study, descriptive statistical indicators such as mean and standard deviation were used to organize, summarize and descriptive information of subjects' characteristics and research variables. In the inferential statistics section, Pearson correlation statistical methods were used to analyze the data using SPSS.22 software. According to the findings, ruminant responses, distracting responses and cognitive emotion regulation were significant predictors of biological stress indices. It can be concluded that biological indicators of stress in patients with gastrointestinal cancer are predictive based on emotional regulation and rumination.

In order to identify weed seeds by machine vision approach, two methods of artificial neural network (ANN) and canonical discriminant analysis (CDA) were applied. The seeds of Amaranthus retroflexus, Amaranthus blitoides, Chenopodium album, Alyssum hirsutum, and Sinapis arvensis were collected and the images of these seeds were recorded. The obtained images were processed and then characteristics related to the shape of each seed were extracted. The extracted data were in in the raw and standardized forms. In addition, main shape characteristics of the seeds were identified by stepwise regression. The results showed that the accuracy of the ANN constructed from the raw and the standard data were 84.30% and 83.39%, respectively. Identification accuracy of ANN was 84.30% and 83.39% for the raw and standard data extracted from stepwise regression. The results of CDA method showed that the identification accuracy of total raw and standard data were 84.9% and 84.7% respectively. Identification accuracy of this method was 82.6% for both raw and standard data extracted from stepwise regression. The highest identification accuracy in both methods (more than 95%) was belonged to A. retroflexus and A. hirsutum. In addition, the seed identification accuracy of C. album in both methods was higher than 87%. This suggests that the use of shape features in pattern recognition models had reliable potential in identifying the seeds of these weeds.

Citizens' participation in the waste management process is achieved by reducing waste generation and separating waste at source as one of the most efficient and economical processing methods in most countries today. Citizens play an important role in the success of this approach to municipal waste management. The purpose of this study was to evaluate and analyze the factors affecting citizen participation in household waste management in Tehran. The research method is descriptive-analytical and the research tool is a questionnaire. The validity and reliability of this study were confirmed by previous similar researches and the opinions of theses professors and thesis advisors. The internal validity (reliability) of the tool (questionnaire) was also demonstrated through Cronbach's alpha with 0.84 for the questionnaires. Ranking of factors affecting the rate of citizen participation in household waste management showed a significant relationship and it was found that each of the factors had different ranking in participation. Also, one-sample t-test, Spearman and Spearman tests were used to investigate the research variables (including gender and education) related to participation in household waste management. There are positive and significant.

Currently one of the most important environmental issues in Tehran is municipal waste management.Although significant improvements in waste management have been made in the last decade, there is still a long way to go to achieve the desired status.The purpose of this study was to evaluate the role of citizen participation in municipal waste management with a focus on separation of origin, which has been studied in District 9 of Tehran.The method of this research is descriptiveanalytical and is of survey type.The research tool was a questionnaire distributed among the citizens at the 9th level.The sample size of the study was 383 using Cochran formula and the same number of questionnaires were distributed to the citizens.Both descriptive and inferential statistics were used to analyze the research data.Descriptive statistics and frequency tables, central index and mean were used to describe the findings. Inferential statistics section was used to evaluate the significance of the regression test using SPSS software.The results showed that the correlation coefficient between public participation and production and storage was0.764.Meanwhile, the resulting R2 is0.509,which indicates that 65% of the dependent variable changes are due to independent variables, indicating the role of citizen participation in waste management in the area

The emergence of the knowledge economy, cause of the increasing importance of intellectual capital as an intangible asset and source of competitive advantage. purpose of this study was firstly to investigate the relationship between intellectual capital with performance and value superior of companies listed in 1390  Using Value Added Intellectual Coefficient Ante Pulic (2000) and the multiple regression model is. In the second stage, these companies using principal component analysis (PCA) based on intellectual capital indicators are ranked and finally using Spearman's rank correlation coefficient , Their ranking of position intellectual capital with the ranking they based stock indexes are compared . The software used for data analysis are Eviews7 is. The results of the research indicates that there is a significant correlation between the intellectual capital with the worth of the company's financial performance and market superior stocks, , but there is not a significant correlation between the ranking of those companies based on index and ranking them based on intellectual capital index. as well as the results of the research show that among the constituent elements of intellectual capital, the capital employed efficiency has created the most influence is the superior companies EPS and human capital efficiency has not a significant impact on the financial performance and market value of the superior companies.
