The present study aimed to provide a model of organizational culture types affecting the perceived organizational performance according to the role of organizational learning has been done. The statistical population of this study includes the employees of the Kohgiluyeh and Boyer-Ahmad Agricultural Jihad Organization. The present study is practical in terms of nature and purpose, in identifying the types of organizational culture of qualitative research, and in identifying the relationships between variables in terms of research method. The statistical population in the fuzzy Delphi method was 15 experts who were sampled by a purposeful judgmental method. At the structural equation modeling, 220 employees were sampled by a simple random method. In order to collect the data, questionnaires were designed in the form of a fuzzy Delphi method and the Likert spectrum. The software used in this study is Smart PLS (version 3), SPSS (version 25), and Excel (version 2016). With the fuzzy Delphi method, between 23 dimensions identified from the literature, 14 were approved by experts. The results of the PLS method indicate that all hypotheses except the effect of the adhocracy culture, development culture, and employees supporting change according to the role of organizational learning on perceived organizational performance were confirmed. The results showed that the leadership component has the highest effect on organizational learning according to the role of organizational learning with a beta of %0.594.

The principles and concepts of the quantum theory have been extensively developed and have become a paradigm in various disciplines, including management and leadership sciences. This is particularly evident in management leadership of educational organizations within universities. Universities must restructure their management leadership methods to effectively address issues and align with the successful higher education systems of other countries. The present study aimed to design a model of quantum curriculum leadership at Farahangian University. The research design was mixed-methods, with an exploratory approach in the qualitative section and a descriptive-correlational approach in the quantitative section. The qualitative section included professors of educational sciences and administrators as experts, while the quantitative section included all professors of educational sciences from Farhangian University. The sample size in the qualitative section was 17 interviewees (faculty members) selected through purposive sampling based on saturation principle, and in the quantitative section, it was 283 individuals selected through cluster random sampling. Data collection tools in the qualitative section consisted of semi-structured interviews, and in the quantitative section, a researcher-made questionnaire with 135 items derived from theoretical foundations, research background, and experts’ interviews. In the qualitative section, validity was assessed through expert judgment, and reliability was assessed through test-retest and internal consistency. In the quantitative section, content validity, structural validity, and reliability were assessed using Cronbach's alpha and composite reliability, indicating the validity and reliability of the instruments. Data analysis in the qualitative section involved grounded theory analysis, while in the quantitative section, descriptive and inferential statistics (Kolmogorov-Smirnov test, Index values and Path analysis) were used. The results of the Kolmogorov-Smirnov test indicated that these assumptions were confirmed (p> 0.05). The findings of the study also showed that the presented model is a good fit. The findings revealed that quantum curriculum leadership consists of two factors including dimensions and components; causal conditions including planning in the higher education system and evaluation of quantum curriculum; and consequences including learning and professional development. The strategies include managerial, applied education, and executive organization, while the context includes environmental, economic, and scientific factors. The obstacles include technology, concentrated education, and structured organization.

One of the factors that should be considered in important management decisions is corporate life cycle; Accordingly, the purpose of this paper is to examine the effects of corporate life cycle on real activities management by considering the role of family ownership. For statistical analysis, data from 106 firms listed on Tehran Stock Exchange from 2013 to 2022 was used. The results of regression analysis of the study showed that firms in the growth stages engage in a higher levels of real activities management via sales management and production cost management than mature firms. However, in the growth stages, they are engage in a lower levels of real earnings management via discretionary expense management than mature firms. Also, the findings suggest that firms in the decline stages engage in a higher levels of real activities management than mature firms. In addition, family firms can be more aggressive in real activities management than non-family firms. The findings of this paper can be used and interest to investors, auditors, regulators, and academics concerning financial reporting quality and financial statement analysis. They can consider the corporate life cycle in their decisions about evaluating real activities management.
