One of the most important stages in human development is adolescence; the period when a person goes through childhood and encounters new plans and responsibilities in the family and society. One of the most critical adolescent issues is adolescents' mental health and well-being. Various research studies have shown that psychological well-being is necessary for many successes and advances of individuals. It should be noted that many factors can increase or decrease psychological well-being; knowing them can be used to help adolescents improve psychological well-being. Various studies have shown that social support is one of the variables that play an important role in well-being. Gratitude is one of the factors that can probably act as a mediator in the impact of social support on people's well-being. Therefore, this study aimed to investigate the role of social support in the well-being of high school students in Ashkezar with the mediating role of gratitude. 

This study was a correlational one (structural equation modeling). The population of this study included all male and female high school students in Ashkezar in the academic year of 2020-2021. A sample of 274 students was selected from the study population by convenient sampling. The research data were collected through Zimment et al.'s Social Support Questionnaire, Morgan et al.'s Gratitude Questionnaire, and Reef's Psychological Well-Being Scale. Data were analyzed by structural equation modeling using Amos-24 software. A bootstrap test was also used to check the indirect effects and mediating roles. Finally, various fitness indices were applied to check the consistency between the data and the conceptual framework. 

Regarding direct effects, the results showed that social support has a positive and significant effect on gratitude (β = 0.73) and psychological well-being (β = 0.63). The results also showed that gratitude positively and significantly affects psychological well-being (β = 0.42). The results of the bootstrap test also showed that in the relationship between social support and psychological well-being, the variable of gratitude could play a mediating role. Finally, the results showed that the proposed model has good fitness.

In sum, according to the research findings, it can be concluded that families and community officials can provide the environment to improve adolescents' mental health by delivering appropriate supportive environments. Also, proper conditions can promote adolescents' psychological well-being by teaching gratitude to adolescents. The results have been discussed in more detail using theoretical bases in the paper.

Continuous auditing is a concept that refers to more frequency of audit reports and tries to use new technologies to lead the audit process towards more automation and reporting of exceptions. Continuous auditing was performed based on the presentation of the desired model. This research was a descriptive correlation study using structural equation modeling. The research community included all certified auditors who are members of the Iranian Association of Certified Public Accountants. The number of samples in this study was estimated to be 110 people who were selected by simple random sampling. A questionnaire was used to collect data. Statistical analysis was performed with LISREL software. Structural equation modeling was also used to test the research hypotheses. The results showed that audit factors such as the use of more analytical techniques and skills in the continuous auditing system, the establishment of risk management systems, improving the effectiveness and efficiency of the internal control system, increasing demand from stakeholders to provide audit reports on the development and rational composition of audit research. Continuous auditing has a significant effect.

Predicting the risk of financial bankruptcy is one of the most important issues in the field of financial decision making of hospitals. In this study, forecasting was done using audit variables and disclosures of audit reports and techniques of C5.0 decision tree algorithm and neural algorithm of ordinary model type and multilayer perceptron (MLP). The research sample including 100 hospitals during the years (2017-2008) was examined through systematic removal sampling. The results show that the model designed by C5.0 decision tree algorithm and neural network algorithms have a prediction accuracy of 61% and 66.7%, respectively, which are the high accuracy of the model designed for these hospitals. is showing .

Interpretive structural modeling is a method for designing systems, especially accounting and management systems. This approach was first introduced by Warfield and has recently been frequently used by researchers in studies for modeling the relationships between variables. This approach makes it possible for the researcher to illustrate the complex relationships between the variables in a rather complex circumstance. It is now considered to be an important tool for organizing and directing the complexity of the relationships between variables. At first, this technique identifies the variables and then specifies the contextual relationships between the variables using the knowledge of experts and their experiences, and finally, it creates a multi-layered structural model. The present study is an applied research of the mixed type in terms of its purpose. In this study, the aforementioned technique was used to structure the factors explaining the causes of business failure (bankruptcy) of agricultural firms in the Tehran Stock Exchange. For this purpose, experts in this field (auditing-financial managers) in the agricultural firms accepted in Tehran Stock Exchange. In addition, 12 variables of audit report disclosures were identified as factors explaining the business failure. Then, the rate of effectiveness of these variables on one another in the model explaining business failure was coded using the initial access matrix. Finally, they were leveled using the final matrix. The results of interpretive structural modeling showed that the factors explaining business failure were modeled at six levels, with the type of auditing opinion at the highest level and had a greater impact on other factors. The highest degree of effectiveness was associated with other disclosures related to environmental-economic-regulatory factors which were at the lower levels. Therefore, it can be claimed that the disclosures associated with environmental-economic-regulatory factors explained the causes of business failure better than other audit variables.

Administrative reform is a systematic, coherent and purposeful process that has a strong and comprehensive relationship with the cultural, social, political and economic structures of society. Therefore, any change in the administrative system will be effective with a coordinated movement in line with the mentioned structures. The purpose of administrative reform is to adapt the roles, capabilities and capabilities of the administrative system, which is one of the requirements for sustainable development. The idea of transforming the administrative system dates back to more than half a century ago. In this article, an attempt has been made to briefly review the goals, necessities, and administrative transformation programs. In this research, the factors affecting management and administrative transformation in employees have been studied on a case-by-case basis.

There are a several factors for determining the level of organization Success. Among that the performance of managers can play a significant rules to satisfy the customers of organization. Thus, evaluating the perfomance of managers must be used in essential goals every organization. In this article, we review kind of appraisal approach in the different aspects and discuss about one model that involve competence factors for evaluating. Then designing one questionnaire with considering goals of Technical University and collecting data wiht distribution questionnaire. Finally,we analyse and compare the results of this questionnaire and discuss about competence of managers.

Buying and selling blood as a common way to provide blood and blood products always have pros and cons. The unique feature of blood with compare to other organs of the body, attention to the blood donors as a permanent and renewable source, ease of transfusion, contributed medical and special applications of this vital element and its products in the fields of pharmaceutical, have led to goods assumption field as well as misuses, and, regardless of the risks of distributing contaminated blood, would jeopardize the moral and human values such as altruism and, put humans as a property. This ends in the intervention of international organizations through making statement, declaration, recommendations and resolutions and consequently, the development of legal systems in order to maintain the dignity and supreme dignity of humans. This study shows that buying and selling blood must be without commodity conception, with respect to being necessary to human life and to monitor the state and the full legislation in this area can be applied.
