Purpose: The purpose of the survey is to determine how theatre directors’ perceive the impact of ongoing technological change on key aspects of theatre management. Design/methodology/approach: The study adopted a qualitative perspective. Empirical data was obtained through interviews with theatre directors. The interviews were in-depth, partly standardised and unstructured. The research sample included theatre directors from different countries. Findings: The research identified aspects of theatre management that are particularly susceptible to the dynamic development of next-generation technology. The theatre managers most frequently perceive the impact of technology in relation to: the meaning and function of the theatre; funding of theatre operations; stakeholder relations; maintaining audience relations; aspects of the production of theatre productions; and staffing policy and the functioning of theatre companies. Strongly negative perceptions of the impact of technology are held by theatre directors on, among other things, the functions and relevance of the theatre, the impact of cultural policy, and the autonomy of arts. In contrast, positive perceptions of the impact of technology mainly related to aspects of the production of theatre performances. Research limitations/implications: The research is primarily limited to theatre directors' perspectives and the purposive nature of the sample cautions against broad claims about the entire population. Moreover, private and not-for-profit theatres are underrepresented. However, these findings could serve as a foundation for quantitative research aiming to generalize and explore new technology implementation processes in theatres. Further research into the implementation of artificial intelligence, perceived as a threat to the arts and theatre companies, seems crucial. Practical implications: The results of the research can be taken into account by theatre directors as they implement next-generation technologies. Originality/value: To the best of the author's knowledge, this article presents the first research on theatre managers' perceptions of ongoing technological changes in key management areas grounded in literature. The study's international scope enhances its value. The findings could benefit theatre directors, cultural organizers, researchers in theatre and cultural management, third-sector organizations in the theatre industry, and developers of new cultural technologies.

It has been determined that in case of clusters of accident-prone wells, the implementation of repair and restoration works and their return to the operational fund, must be carried out based on economic and technical efficiency. The corresponding analysis revealed that clusters characterizing the accident rates include issues with downhole pipes, downhole motors, tools and devices, packers, bottom hole drill pipes, cables, ropes, wires, and others types of accidents. This paper presents the accumulated results of realized RRW (repair restoration works) based on field experience for formalization and automation in developing decision-making technologies and selecting accident elimination strategy in appropriate field conditions. Various technologies have been developed for the elimination process, using appropriate equipment. Repair and restoration work for corresponding codes is proposed based on field statistical information. The economic feasibility of the obtained results and their application are classified on the basis of boundary conditions defined by developed logical stages. The logical stages are drawn up using information about field parameters, including well conditions, the location of the accident object in the well, realized technology, and appropriate technical means. As a result of the analysis of SOCAR (State Oil Company of Azerbaijan Republic) fund of accident-prone wells, 24 possible options for the implementation of RRW have been identified for the aforementioned clusters. Lists of the existing tool park, functional design parameters, and technological modes necessary for each accident cluster have been determined to implement decision-making technologies.

Understanding the anomalies generated by various subsurface targets and their responses to different geophysical techniques in various subsoil types is critical to near-surface geophysical investigations. Geophysical test site (GTS) plays a vital role in near-surface geophysical investigations and related Earth sciences to adequately predict the geometries and anomalies generated by the subsurface targets. Therefore, developing a GTS on a site requires some technical efficiencies, mechanical procedures, engineering concepts and scientific approach, depending on the operating environment and the purpose of construction. This paper reviews the evolving roles of GTS in engineering, sciences, and technology via remarkable pedagogical and scientific research. The procedures for designing and installing GTS were also discussed. Every constructed GTS is unique and has its operating environment and sets of scientific requirements. As a result, the execution of GTS should be subjected to numerous factors that invariably affect the overall long time usage and performance. Comparative studies of GTS activities indicate that GTS is a vital geophysical research and academic platform to enrich the outcomes of the geophysical modelling for near-surface geophysical applications in engineering, science and technology. The evolving application of GTS has greatly impacted the field of science and engineering by enhancing the knowledge and understanding of the earth’s interior, which invariably affects the engineers, geophysicists, archaeologists and geologists to be critical in the analysis, interpretation, and providing precise and accurate information of subsurface anomalies underlying the uppermost soil of the earth’s crust. After a critical investigation, it was noted that the installation of GTSs is usually conceived to replicate situations often encountered in field investigation contexts. Examination shows that GTS can provide an ideal platform for young geoscientists, engineers and archaeologists to acquire the requisite skills, knowledge, technical know-how, and professional techniques for resolving near-surface challenges in real-life work situations. More also, a well-developed and equipped GTS could be a watershed in technological advancement, research development, and new scientific ideas. The GTS platform also indicates a promising pedagogical approach to geophysical educational usage, research mobilization, and development of new shallow geophysical techniques for various near-surface investigation and calibrating/testing geophysical equipment, which invariably catalyzed engineering designs, scientific concepts and technological advancement.
