This study aims to investigate the role of digital twins in enhancing the efficiency, quality, and competitiveness of small manufacturers, identifying key motivations, impacts, challenges, and future benefits. This qualitative study employed semi-structured interviews to gather in-depth insights from 28 key stakeholders in small manufacturing businesses that have implemented digital twin technology. Participants included business owners, operations managers, and IT specialists. The data were transcribed and analyzed using NVivo software, following a thematic analysis approach to identify and categorize recurring themes and concepts. The analysis revealed four main themes: Adoption of Digital Twins, Impact on Manufacturing Efficiency, Challenges and Barriers, and Future Outlook and Benefits. Key motivations for adoption included cost reduction, efficiency improvement, and competitive advantage. Digital twins significantly enhanced manufacturing efficiency through process optimization, quality control, and cost management. Major challenges encompassed technical barriers, financial constraints, organizational resistance, and regulatory issues. The future outlook for digital twins was positive, with potential long-term benefits and advancements in AI and IoT expected to further enhance their capabilities. Digital twins offer substantial benefits for small manufacturing businesses, including improved efficiency, quality control, and cost management. However, successful implementation requires addressing technical, financial, and organizational challenges. With continued technological advancements and strategic support, digital twins are likely to become integral to small manufacturers, driving innovation and competitiveness in the industry.

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.

In recent decades, scientists and researchers have not yet paid attention to some scientific debates and studies despite the scientific development of tourism. Tourism paradigms and related socio-cultural theories are two of these areas. In this work, we aimed to explain how tourism's socio-cultural theories and debates form in cultural and historical contexts. This work presents a comprehensive image of tourism socio-cultural theories’ formation and evolution process. This study a fundamental and theoretical research. It is descriptive-explanatory in terms of purpose, longitudinal in terms of time, and historical-comparative in terms of data collection and analysis. The data used in this study is archival. The results showed that although humanism, interpretivism and structuralism paradigms have significantly impacted the formation and evolution of tourism development, the functionalism paradigm dominates all periods of development and evolution of tourism from pre-mass to post-mass. There are signs in the field of turning tourism paradigms toward subjectivism approaches, based on the findings of this research and futurology in this field. Therefore, it seems that tourism scientists and researchers’ attention to this socio-cultural change of approach and the readiness of managers to understand this "paradigmatic shift" and its application in the field of implementation is undeniable.
