Significance of leadership styles on crew resource management and aircraft accidents
(American Institute of Aeronautics and Astronautics, 2025) Amiri, Misagh Haji; Kuşakcı, Sümeyye; Güngör, Habibe
Over the past few decades, human error has surpassed system malfunctions as the primary cause of aircraft accidents due to advancements in aviation technology. Crew Resource Management (CRM) has emerged as a pivotal tool to mitigate human errors and optimize operations. Effective leadership is a cornerstone of successful CRM. This study investigates the impact of various leadership styles on CRM performance and its effect on aircraft accidents. By analyzing cockpit voice recorder transcripts and official accident reports from five major accidents per decade between 1970s and 2010s, it is found that both democratic and autocratic leadership, in their extreme forms, can negatively influence CRM skills and cause accidents. While the hierarchical structure of aviation necessitates some degree of autocratic leadership, democratic leadership can foster continuous communication among crew members, a vital aspect of safe operations. Our findings suggest that flight leaders should adopt a contingency-based leadership approach, adapting their style to the specific demands of each situation to ensure safe and efficient flights. This research contributes to airline CRM training programs and flight safety policies. Its evidence-based findings provide practical guidance for educators to design effective CRM training. Analyzing crew conversations during crises offers valuable insights for trainees/students to understand appropriate leadership.
The effect of perception and experience of students toward VR in architectural education
(Society for Science and Education, 2024) Özeren, Ömer; Qurraie, Bahar Sultan; Juba, Ibrahim; Amiri, Misagh Haji
This study investigated the potential of integrating Building Information Modeling (BIM) and Virtual Reality (VR) to enhance spatial perception and the design process in an architectural design studio setting. Undergraduate students at Karabük University designed the interior of a historical leather factory to be converted into a library using Revit and Unreal Engine 5. The findings revealed that VR technology significantly improved students' understanding of design details, spatial relationships, and the overall design process. Students were able to visualize their designs in a more immersive and interactive way, leading to more informed decision-making. Interactive elements, such as lighting controls and material selections, contributed to a more realistic and engaging experience. While visual realism played a role in the effectiveness of VR, the study also highlighted the importance of factors beyond visual realism, such as user experience and presence. These factors can influence how students interact with and learn from the VR environment. Future research is needed to further explore these factors and identify strategies for optimizing VR integration in design education. Overall, this study demonstrates the potential of BIM and VR to transform architectural education by providing students with a more immersive and interactive learning experience. However, it is essential to consider factors beyond visual realism to ensure the effective integration of VR into the design processp.
Evaluating urban square management success: A model for urban public spaces in Istanbul
(Elsevier B.V., 2025) Erce, Vural; Kuşakcı, Ali Osman; Haji Amiri, Misagh
Urban public spaces, particularly city squares, play a critical role in fostering community interaction, enhancing socio-cultural well-being, and contributing to the overall cultural value of a city. Effective planning and management of these squares are essential to ensure accessibility, functionality, and inclusivity, thereby enabling them to serve as dynamic centers for social engagement and urban life. Prior research has often neglected the public's perspective in square planning and management. Thus, this study aims to develop an Urban Square Management (USM) success score model to assess the effectiveness of urban squares planning from the public's perspective. Initially, expert evaluations of relevant criteria were conducted using the Interval Type-2 Fuzzy Analytical Hierarchy Process (IT2F-AHP), chosen to address the uncertainties and subjective judgments inherent in expert assessments. The resulting weighted criteria formed the basis for a user questionnaire. A total of 157 questionnaires were collected from visitors at Uskudar Square in Istanbul, a recently redesigned public space. The data underwent Exploratory Factor Analysis to identify key factors and refine the model's structure. Applying the developed USM model to Uskudar Square resulted in a success score of 70.2, providing an overall evaluation of the square's management performance. Crucially, the model allows for a detailed analysis of the constituent sub-dimensions contributing to the total score, such as accessibility, safety, maintenance, amenities, social activity, and environmental quality. This granular perspective enables urban planners and managers to identify specific areas requiring improvement and implement targeted interventions to enhance the overall quality, usability, and public satisfaction with urban squares.
An application of quadratic EKC model: Energy use, economic development, and environmental quality for Thailand
(International Research Alliance for Sustainable Development - iRASD, 2020) Ungwanitban, Jidapa; Nawab, Tabish; Shah, Syed Moin-ud-Din
This study examines the validation the relationship of environmental and energy for Thailand. Further this study examined the impact of economic growth, non-renewable and renewable energy and FDI on environment, with the help of time series data from 1990 to 2018 with ecological damage indicator, i.e., emission of carbon dioxide (CO2). This study applied Autoregressive (ARDL) Distributed Lag model for testing the cointegration in the model. In the long run, the results of this study confirm the existence of cointegration in the model. However, the negative effect of growth on the environment confirms the existence of the Kuznets Environmental Curve (EKC), which means that economic growth harms Thailand’s environment. Renewable energy and foreign direct investment are the key aspects that reduce environmental degradation in Thailand during the study period. Therefore, the government must redouble its efforts to reduce carbon dioxide CO2 emissions, perhaps through regulatory intervention or mandatory renewable energy applications for individual household and industrial segments. For example, the manufacturing sectors, iron, and steel must prioritize, reducing the high non-renewable energy consumption for those which are renewable. The government must introduce specific measures and campaigns for environmental protection for future generations as well as introduce taxes for polluters. Another relevant recommendation is to create an industry that relies on low energy consumption compared to high productivity levels.
Impact of renewable energy consumption and health expenditure on air pollutants: Implications for sustainable development in ASEAN countries
(International Research Alliance for Sustainable Development - iRASD, 2021) Nawab, Tabish; Afghan, Mohibullah; Muneza, Christian
This study examined the association between economic development and environmental degradation in the presence of health expenditure and renewable energy for selected 6 ASEAN nations covering the period of 2000 to 2018. Before estimating the model, firstly check the stationary of variables for this purpose Levin Lin Chu unit root applied, results indicate that all variables are stationary at level. GMM is efficient in eliminating fixed/random effects in the model and overcoming the problem of endogeneity. For causal analysis, we used Granger causality test. The results indicate a bidirectional association between the consumption of energy and carbon emission. There exists a uni-directional association among Economic development, expenditure on health, and environmental degradation. GMM results indicate that spending on the health sector and the consumption of renewable energy sectors decline the environmental degradation level; on the other hand, economic growth boosts the ASEAN nations' carbon emission level. The study's recommendation is to increase the level of economic development by enhancing the energy sector from nonrenewable energy to renewable energy. As it boosts the level of economic growth, which ultimately improves health development and technologies, which will strengthen the health facilities in the nation and reduce the level of carbon production that helps keep the environment healthy and clean.
