Introduction: One of the primary functions of the study and development centers at medical universities nationwide is to enhance teaching quality. To achieve this, various methods are employed to assess teaching effectiveness. One such method involves evaluating professors' teaching quality through Interactive student Committees during the academic semester. This study aims to examine the impact of forming these Interactive student Committees on teaching quality at the School of Allied Medical Sciences, Ahvaz Jundishapur University of Medical Sciences. Methods: This descriptive cross-sectional study was conducted at the School of Allied Medical Sciences, Ahvaz Jundishapur University of Medical Sciences, in 2021. The research population comprised BSc students who enrolled in the School of Allied Medical Sciences in 2018, 2019, and 2020 and participated in forming Interactive student Committees. The research tool was a questionnaire developed by the researcher, consisting of four main sections. After confirming the questionnaire's validity and reliability, it was distributed to the target sample via email and messaging platforms. Descriptive and inferential methods were used to analyze the collected data using SPSS software (version 24). Results: A total of 57% of the questionnaires were completed and returned by the participants. The analysis of boxplots related to students' responses on presenting weekly reports on teaching quality showed a normal and balanced distribution. The greater dispersion of scores above the median indicated a significant positive relationship. Additionally, there was a significant relationship between presenting weekly reports and the presence of problems in presenting these reports (p < 0.05). Conclusion: Overall, the study findings indicated that forming Interactive student Committees can be beneficial and influential in enhancing both the quality and quantity of teaching provided by professors.

Reservoir permeability is a critical parameter for the evaluation of hydrocarbon reservoirs. There are a lot of well log data related with this parameter. In this study, permeability is predicted using them and a supervised Committee machine neural network (SCMNN) which is combined of 30 estimators. All of data were divided in two low and high permeability populations using statistical study. Each estimator of SCMNN was combined of two simple networks to predict permeability in both low and high classes and one gating network, considered as a classifier, classified data to these two classes. Thus, each low and/or high input data would predict in related network. This SCMNN was used to predict permeability on the data of one of petroleum reservoirs of south-west of Iran. 210 samples of this reservoir were available. Because of the fewness of data 80% of them were used as training data and 20% of them were used as validation and testing data. The overall fitting between predicted permeability versus measured ones was qualified through R2 (R=correlation coefficient) to be 97.72% which is considered appropriate. Whereas, R2 in the simple network in the best stat was 84.14%. The high power and efficiency of SCMNN are indicated by lower bias and better R2 in results.

The inherent duty of urban design is to manage the improvement of urban design qualities in both content and procedural dimensions. Without simultaneous attention to these two, even the purest urban design theories may remain ineffective in reality. Improving the quality of the landscape, in addition to the need to formulate comprehensive, clear, and more or less flexible regulations, requires the definition of a precise and efficient executive structure so that it can be a suitable leverage for the implementation of these rules. Façade Committees are one of the methods regarded for the control and implementation of these approvals, which play a significant role in achieving the goal of landscape improvement. Mashhad City has been one of the main pioneers in this field in the country by compiling approvals and forming Committees to control and guide urban landscaping. The present research aims to evaluate the performance of the Mashhad façade Committee by examining its damages, challenges, and achievements as well as providing effective suggestions to improve this performance. Applying a mixed method and alignment methodology, this study has evaluated the performance of the façade Committee in two quantitative and qualitative phases. The research findings state that the most important challenges of façade Committees are qualitative decisions, applying personal interest, weakness of legal position, and lack of criteria for action and executive guarantee. It's most important achievements are drawing the attention of the specialized community to the significance of the public landscape, citizens' rights and interests, and strengthening the architects' position in the development process. Some suggestions have been proposed for improving the performance of the façade Committee in the procedural section that includes improving the organizational administrative level of the façade Committee, forming a project steering Committee, preparing periodical performance reports. Some other suggestions were proposed in the case of the content section, including planning for participation and opinion polls, and acculturalization for Iranian architecture promotion.

In the past decade, In order to develop corporate governance in Iran, regulatory authorities such as the Central Bank of the Islamic Republic of Iran (CBI) and the Securities & Exchange Organization (SEO) have mandated establishment of Audit Committee(AC) in companies and credit institutions through issuing guidelines and requirements. Due to immaturity of AC in Iran, there are many obstacles and challenges in front of it and on the other hand, many aspects of AC, including the challenges of its implementation in Iran, are less explained. Many aspects of the AC in Iran, including the Audit Committee Effectiveness (ACE) and it's obstacles and barriers, have not been clarified yet. Also, limited areas of the Audit Committee’s Challenges (ACC) and barriers have been considered in previous research. In order to explain and describe the various aspects of ACC and it’ s improvement strategies, by using the qualitative approach and Grounded Theory(GT), AC multi-stakeholders were studied for the first time in Iran. In this regard, 34 Participants were interviewed. In addition, 31 papers and seminars which published in Iranian professional magazines that reflect the viewpoints of the above-mentioned stakeholders were also used and analyzed. The data were analyzed by using the open coding, axial coding & selective coding approach that are specific to the GT and major categories, categories, and subcategories (concepts) were extracted. The ACC model as an emerged theory was designed. The model incorporates multidimensional of ACC.

As an integral part of the corporate governance structure, the audit Committee is charged with overseeing the financial reporting process, and limiting earnings management is one of the main benefits of companies with an audit Committee. Hence, this study examines the relationship between the characteristics of audit Committee and accrual earnings management. For this purpose, we investigate the data of 88 companies listed by Tehran Stock Exchange for the period 2014 of 2016. The results of the research indicate that the participation of financial experts in audit Committees, increasing the independence and size of audit Committee has a significant relationship with less earnings management. Also, the results indicate that there is a U-shaped relationship between audit Committee independence and earnings management. In other words, the low independence of the audit Committee will not be able to prevent managers' opportunistic behaviors. So, when the majority of members of the Audit Committee are independent (over 50%), Audit Committee independence is leading to lower earnings management. In addition, the results of the research indicate that there is an inverse U-shaped significant relationship between audit Committee meetings and earnings management. In this case, holding monthly audit Committees (12 meet a year) has the most effectiveness in preventing earnings management. The “, effective”,number of audit Committee meetings is determined at the minimum of the curve (minimum level), reflecting the lowest level of discretionary accruals.
