Achaemenid architecture is distinguished by its columned halls and porticoes, which can be found in the empire’s major capitals, such as Pasargadae, Susa, and Persepolis. Column bases are one of the most essential parts of a column, and square and bell-shaped column bases were frequently used during the Achaemenid period. During a 2018 survey conducted in Hannā, Semirom County, Esfahan Province, the authors discovered two square-column bases that showed a striking resemblance to other column bases found in the Achaemenid Empire. The column bases, along with several partly carved slabs, were found by a bulldozer during the digging process. If these column bases and carved slabs are indeed from an Achaemenid period construction, it serves as a strong indication of the importance of the Hannā site in Semirom. An additional indication of the significance of these findings is the lack of palaces or buildings with columns from the Achaemenid period in the region of Esfahan. Furthermore, it is essential to take into account the continued use of square-column bases in post-Achaemenid structures, as well as the fact that the masonry tools employed during this period remained unchanged throughout the following centuries. By analyzing the presence of carved stone slabs and columned bases of pillared buildings and halls from the Achaemenid period and beyond, we may determine that we are dealing with a prestigious structure that is associated with the elite of society. After the decline of the Achaemenid Empire, pillared structures and this type of square and stepped column base were used.

This study explores the analogy between Ralph Waldo Emerson’s Transcendentalism and his mystical experience through a phenomenological lens, emphasizing cross-cultural cognitive dimensions and their impact on the concept of universality. The research addresses the contemporary relevance of this analogy in an era marked by scientific advancements that, while clarifying many misconceptions, fail to provide existential reassurance or answer all human inquiries. This reflective inquiry seeks to understand reality and the rational linkage of events by engaging with life’s forces, which are integral to human wonderment. The methodology involves a comparative analysis of Emerson’s themes of intuition, light and knowledge alongside Tymieniecka’s Phenomenology of Life. The study does not aim to offer practical solutions but rather provides a philosophical account of intuition’s role in human experience, addressing fundamental challenges at their core. The findings suggest that Emerson’s mystical experiences, when analyzed through his themes of light, intuition and knowledge, align with phenomenological signification on an intuitive basis. Emerson’s Transcendentalism reflects life’s ontopoietic dynamism, perceiving universal structures akin to eidetic intuition essential for mental functionality. This study underscores the philosophical potential inherent in merging transcendental thought with phenomenological inquiry, offering new insights into understanding universality across literary contexts.

Objective : In recent years, big data analytics (BDA) technologies have garnered increasing attention from researchers. However, limited empirical research has explored the benefits of BDA in supply chain integration and lean operations and its influence on sustainable performance in the healthcare sector. To address this gap, the research aims to design and present a conceptual model to investigate the relationships among supply chain integration, lean operations, sustainable supply chain performance, and BDA capabilities. Methods : This research adopts a survey-based approach, using an online questionnaire to collect data from 104 public and private hospitals in Iran. Data analysis was conducted using structural equation modeling (SEM) via the Partial Least Squares Method (PLS-SEM).  Results : The results revealed that BDA capabilities directly improve sustainable supply chain performance. Moreover, lean operations and supply chain integration mediate between BDA capabilities and sustainable performance. It was also found that BDA capabilities enhance both lean operations and supply chain integration, with supply chain integration directly impacting lean operations. These findings suggest that BDA capabilities can be leveraged as a key enabler to strengthen lean operations, improve supply chain integration, and achieve sustainable supply chain performance. Conclusion : While some literature has addressed various aspects of supply chain digitalization, no prior research has specifically examined the potential impacts of BDA on sustainable and lean supply chain performance within the healthcare sector. The results offer meaningful contributions for academic researchers interested in the topic, business professionals specializing in digital supply chain management and sustainable operations, healthcare organizations, and any stakeholders seeking to better understand the influence of BDA on sustainable operations and overall business performance.
