Introduction: Due to the limited resources and facilities that organizations face, we must first identify and prioritize the factors that are of higher importance to customers and will lead to their satisfaction, and then based on priority and importance. Agents took the necessary measures to provide goods and services that meet the highest degree of customer satisfaction. Therefore, the purpose of this study is to rank the criteria and sub-criteria affecting the decision to buy steel ingots customers and, in this regard, the role of ethical factors has been considered. Material and Methods: The method used in this research is DANP method. The statistical population was experts, business managers and CEOs of companies buying steel ingots, 19 of which were selected by purposive sampling. The analysis tool was an interview and a questionnaire. The data analysis method was Dematel method and drawing their causal diagrams and ranking the factors influencing the decision-making process of steel ingots using ANP method. Results: The results showed that the criterion of economic factors of purchase with a weight of 0.2208 ranked first, the criterion of specific factors of seller with a weight of 0.1998 second, the criterion of ethical factors with a weight of 0.1952 third, the criterion of specific factors of product with a weight of 0.1923 fourth and finally Buying conditions factors with a weight of 0.1919 are ranked fifth. Conclusion: The present study showed that the main factors in customers' purchasing decision include economic factors, seller-related factors, ethical relationship, product-related factors and factors related to purchase conditions

The purpose of this study is evaluate the out-of-home advertising model of consumer products in the food industry of Fars province. The model under test was designed using the grounded theory method through interviews with 20 marketing and advertising experts. Structural equation analysis has been used to analyze the data and according to the proposed model in relation to the effect of latent variables. Data were collected by distributing a questionnaire among the marketing and sales staff of Fars food industry companies. The statistical population of this study includes the employees of the marketing and sales department of Fars food industry companies. Due to the unlimited number of statistical population, a cluster model was used to select the sample. For this purpose, 246 people were selected and evaluated in a targeted manner, but in the end, 227 completed and returned questionnaires were statistically analyzed. According to the results, the two important models of model fit (RMSEA) and (CMIN / DF) and other indicators are in an acceptable range, which can be said that the model has a good fit. Also, the research results showed that Out-Of-Home advertising can It should lead to customer loyalty, credibility, mental engagement, intention to buy and increase sales.

As a significant consequence of internal and external characteristics in auditors, independence plays a vital role in promoting professional judgment in auditing. This dimension of individual audit functions has always been considered one of the areas studied in this profession due to its integration with the perceptual and often intangible features of auditors’ behavior. Therefore, this study, understanding the importance of independence functions in the auditing profession, seeks to identify the characteristics of inertia as a stimulus for independence in auditing in the petrochemical industry to act on its interpretive ranking. This research is a mixed method due to the nature of data collection. It first uses interviews to identify the characteristics of inertia in the auditing profession and then employs the checklists of the pair scale to determine the interpretive ranking. Accordingly, the grounded theory and the quantitative part are used in the qualitative part, and Delphi analysis and the interpretive ranking process are used. The statistical population in the qualitative section were 12 auditing professionals who, in terms of theoretical knowledge, had the necessary capabilities to develop the concept studied in this study. They were selected through theoretical sampling based on the snowball technique. The statistical population in the quantitative part were 19 auditors with work experience in the petrochemical industry and a level of technical and specialized knowledge; they were selected using homogeneous sampling. The research results in the qualitative part indicate the existence of 3 categories, 8 components, and 35 concept codes that have laid the inertial features in the auditing profession in the form of an 8-dimensional integrated model. On the other hand, the results in the quantitative part show that the percentage of influence of the locus of control feature is higher than other inertial features in the audit profession in the petrochemical industry, implying that the auditor’s encirclement on individual control in success and failure can avoid a set of external factors such as chance and lead fate in audit functions. In other words, an auditor with the characteristics of an internal locus of control tries to use his/her ability to express independent behavior in professional comments and judgments, regardless of external reasons

The present study aims to examine the relationship between cost stickiness and conservatism levels according to the type of industry. This purpose is achieved using the combined data technique and three models of non-operating accruals, the Basu model, and the market value model with a sample consisting of 113 companies listed on the Tehran Stock Exchange (TSE) over the period 2011 to 2020. Findings show that based on the model of non-operating accruals in the automotive, pharmaceutical, chemical, and food industries, cost stickiness decreases the level of conservatism. However, in the machinery industry, the relationship is significantly based on this model, but cost stickiness does not reduce the level of conservatism. According to the Basu model in the chemical, food, and basic metals industries, cost stickiness reduces the level of conservatism. But in the pharmaceutical industry and machinery and equipment, there is a significant relationship according to this model, but cost stickiness does not decrease the level of conservatism in companies. Also, based on the market value model in the automotive, chemical, machinery, and basic metal industries, there is a significant association, but cost stickiness does not decrease the level of conservatism in companies.
