Abstract
The present study was an attempt to investigate the effect of ethical standards including ethical environment (instrumental environment, favorite environment, independent environment, normative environment, efficiency-based environment and regulation-oriented environment), professional commitment, ethical values and ethical ideology (idealism and relativism) on performance of auditors. The population of this study consists of auditors of auditing firms affiliated with Iranian association of Certified Public Accountants and certified independent auditors. To calculate the number of samples and to take samples, coceran fornulation and the avilable sample methods have been respectively used. This study was conducted in 2020. 300 auditors participated in the present study and completed the questionnaires distributed among them. The partial least squares (PLS) method was used for modelling and hypothesis testing purposes. The results  show that all the subsets of ethical environment (instrumental environment, favorite environment, independent environment, normative environment, efficiency-based environment and regulation-oriented environment) have a positive and significant correlation with auditor performance. As for the subsets of ethical ideology, idealism and relativism were found to have a significantly positive and a significantly negative correlation with the performance of auditors, respectively. The results also show that the main variables of the study (ethical environment, professional commitment, ethical values and ethical ideology) have a positive and significant effect on the occupational performance of auditors. Applying the results of this research can help to develop theoretical foundations in the field of the ethical behavior in auditors as well as to increase their level of awareness and ethical development. It also increases the understanding of auditorschr('39') behavior in the face of ethical conflicts.

The purpose of this study is to investigate the factors affecting the professional commitment of accounting students as a result of the anticipatory socialization process and in the framework of the college impact model of input-environment-output. This study is a descriptive and correlational research and the statistical population of this study consists of accounting final year undergraduate students of public universities across the country. The information required for this study was collected by completing a questionnaire by 190 students in 2020. In order to test the hypotheses, the partial least squares structural equation modelling has been used. The results of the study indicate a positive and significant effect of studentschr motivation and their involvement on professional commitment. The results also show a positive and significant effect of studentschr motivation on the perceived environment and their involvement. In addition, the results suggest that student involvement plays a mediating role in the relationship between motivation and professional commitment as well as in the relationship between perceived environment and professional commitment. The results of this study indicate that the input-environment-output model can provide a suitable framework for examining the process of anticipatory socialization and explaining the factors affecting the professional commitment of accounting students, as the outcome of the anticipatory socialization process.

This study investigates the effect of religiosity and professional commitment on audit quality. Also, the moderating role of the auditor's dysfunctional behavior is examined in this regard. This research is an applied research in terms of purpose and falls into the category of survey-descriptive research as well as quantitative studies. The statistical population of the study consists of all auditors working in the field of auditing. The required data were collected using a questionnaire completed by 385 employees of auditing firms members of the Iranian Certified Public Accountants in 2021 and using statistical methods Pearson correlation coefficient and linear regressions. Multiple regressions were used via SPSS software. The results of testing the research hypotheses show that religiosity and professional commitment have a positive and significant effect on audit quality. In addition, the auditor's dysfunctional behavior has a negative and significant effect on the quality of the audit. Therefore, the more the auditor adheres to the religion as well as the professional commitment, the higher audit quality can be done in performing its duties. Also, the auditor's dysfunctional behavior has a negative and significant effect on the quality of the audit. Reducing the dysfunctional behavior of the auditor will increase audit quality. Another finding of the study was that religiosity and professional commitment do not affect the auditor's dysfunctional behavior, therefore, the auditor's dysfunctional behavior does not mediate the relationship between religiosity and professional commitment with audit quality. Therefore, a committed auditor will not exhibit ineffective behavior. With increasing religiosity and professional commitment, audit quality increases.
