Does Nepotism Affect Employee Job Performance? A Case Study of Frontline Staff in the Aviation Industry
type: item
description: Despite a growing body of research on nepotism, the specific relationship between nepotism and employees’ in-role and extra-role performance—along with its underlying mechanisms—remains relatively underexplored. Drawing on Conservation of Resources (COR) Theory, this study identified a key cognitive mediator linking perceived nepotism to both forms of job performance. Empirical data were collected from frontline aviation staff, and the proposed model was tested using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings reveal that nepotism significantly increases perceptions of employment job uncertainty, which in turn negatively impacts both in-role and extra-role performance. These results contribute to the nepotism literature by identifying a cognitive mechanism through which nepotistic practices undermine employee behavior. The study also offers practical implications for organizations seeking to improve service quality by addressing perceived favoritism and its psychological and behavioral consequences

Experimental Validation of UWB-Based Fault-Tolerant Control for Quadcopters Subject to Actuator Failures
type: item
description: This paper presents a fault-tolerant control algorithm for a four-rotor unmanned aerial vehicle (quadcopter) using an Ultra-Wideband (UWB) positioning system. The proposed control system allows the vehicle to maintain flight stability and position control capability even in the case of a partial actuator failure (motor efficiency degradation). The approach is based on a combination of reconfigurable control, adaptive control, and an observer-based state/los+s monitor. The validity of the method is demonstrated through Lyapunov stability mathematical analysis and verified by real-world flight experiments in an indoor environment using UWB. Experimental results show that the system maintains attitude stability, position hold, and altitude with acceptable errors when a fault occurs, thereby confirming the feasibility and effectiveness of the controller

Optimizing Aircraft Fleet Assignment in Airline Route Networks Using a GA-Based Allocation with Greedy Chain Assignment under Operational Constraints
type: item
description: The fleet assignment problem remains a critical challenge in airline operations, where heterogeneous aircraft must be allocated to scheduled flights in a manner that minimizes total costs while satisfying operational constraints. This paper formulates the problem as a cost minimization model that incorporates both operating expenses and passenger spill costs under constraints of fleet size, airport balance, and time-space network feasibility. Due to the combinatorial nature of the problem, traditional method often faced with poor scalability when increase problem size. To address this, we propose a Genetic Algorithm (GA)-based approach enhanced with a greedy chain assignment and repa ir mechanism to efficiently enforce airport balance and availability constraints. Numerical evaluations are conducted on small-scale and large-scale test cases under multiple cost-per-available-seat-mile (CASM) scenarios. The numerical evaluation highlights the effectiveness and adaptability of the proposed GA-based framework in solving fleet assignment problems

The Impact Of Trust In AI On Inspiration And Intention To Use AI In Teaching Among University Lecturers
type: item
description: This study investigates the relationship between trust in AI, inspiration, and faculty intention to use AI in teaching, integrating the technology acceptance model (TAM) and cognitive emotion theory (CET). Using partial least squares structural equation modeling (PLS-SEM), data from 332 university lecturers in Ho Chi Minh City were analyzed. The results reveal that trust in AI outcomes (β = 0.441) and inspiration (β = 0.412) significantly and positively influence intention to use AI in teaching. Notably, inspiration mediates the relationship between trust and intention (indirect effect β = 0.213), highlighting its critical role in translating trust into actionable intentions. The proposed model explains 59.5% of the variance in AI usage intention, confirming its robustness. Additionally, trust in AI outcomes strongly predicts inspiration (β = 0.517), emphasizing the importance of fostering both trust and emotional engagement to enhance AI adoption in higher education. Based on these findings, the study suggests practical strategies, including developing an “AI Trust Ecosystem,” launching an “AI Inspiration Movement,” and implementing an “AI-Integration Roadmap”. These strategies aim to build trust, inspire faculty, and ensure effective AI integration in teaching practices. The study contributes to expanding TAM by incorporating emotional factors from CET, offering a novel perspective on technology acceptance in education.

Linking E-Leadership To Digital Adoption In Smes: The Role Of Digital Orientation And Fear Of Failure
type: item
description: In the context of increasing digital transformation, this study investigates the influence of e-leadership on digital technology adoption by examining the mediating role of digital orientation and the moderating effect of fear of failure. Drawing on the Technology–Organization–Environment (TOE) framework and Diffusion of Innovation (DOI) theory, a research model was developed and tested using data collected from 284 employees working in Vietnamese small and medium-sized enterprises (SMEs). Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed to assess the hypothesized relationships. The results indicate that e-leadership positively influences digital technology adoption, both directly and indirectly through digital orientation. Moreover, fear of failure was found to negatively moderate the relationship between e-leadership and technology adoption, but not the relationship between digital orientation and technology adoption. These findings highlight the critical role of digital leadership and individual digital commitment in facilitating adoption, while also emphasizing the need to address psychological barriers. The study offers theoretical contributions by integrating the TOE and DOI frameworks and provides practical insights for organizations navigating digital transformation.

type: item
description: The rapid integration of service robots in transportation hubs such as airports has transformed how passengers interact with service technologies. As early adopters, Generation Z plays a crucial role in shaping the future of robot-assisted services. This study explores the factors influencing Gen Z passengers’ willingness to use airport service robots through the lens of the Cognitive-Affective-Normative framework. Specifically, the study examines the roles of perceived smartness (cognitive), hedonic value (affective), and social influence (normative) in shaping users’ willingness to use airport service robots . Using a hybrid approach combining Partial Least Squares Structural Equation Modeling and Necessary Condition Analysis, the findings confirm the significance of all three dimensions. Importantly, perceived smartness of service robots and hedonic value emerge as both sufficient and necessary conditions. The study extends the Cognitive-Affective-Normative framework to the airport context and offers practical implications for enhancing service robot design and engagement strategies tailored to Gen Z users

Infrastructure For Safe Distance Management On Expressways: Lessons From France For Vietnam
type: item
description: Maintaining a safe distance is a key factor in preventing accidents on expressways. In practice, drivers estimate this distance based on experience, assistance from in-vehicle devices, or support from expressway infrastructure. However, the technical infrastructure on Vietnam’s expressways currently remains limited and lacks continuity in supporting safe distance determination. This study evaluates the current state of technical infrastructure supporting safe distance identification on Vietnamese expressways and compares it with the well-developed system in France. The research collects and analyzes domestic and international regulations, technical requirements, and practical implementations. Results show that infrastructures such as lane markings and signs in Vietnam are installed sporadically, without continuous coverage along the expressway, and are mostly absent in tunnels. In contrast, France systematically integrates safe distance support throughout the entire route, using elements like lane markings and blue lights or chevrons, including inside tunnels. Based on these comparisons, the study proposes improvements for Vietnam by integrating safe distance support into existing infrastructures, such as emergency lane markings, and adding visual signals in tunnels. These improvements should be standardized in regulations and circulars and incorporated into driver training programs to enhance implementation effectiveness and reduce accidents related to safe distance issues.

type: item
description: This paper presents a combustion simulation for an aircraft piston engine. The aim of this research is to develop a combustion model using accessible and feasible computational tools, ensuring both high accuracy and practicality as a foundation for more advanced studies. The developed model is a zero-dimensional (0-D) and mean-value engine model (MVEM) for a single cylinder, fundamentally based on the first law of thermodynamics. It is meticulously programmed using Matlab, allowing for a detailed description of the intricate relationships among various internal engine characteristics, including cylinder performance parameters, heat release, heat loss, in-cylinder pressure, and an initial estimation of exhaust gas emissions were conducted for the engine operation. Specifically, the heat release process is modeled using the well-established Wiebe function, while heat loss is calculated using the Woschni model, which accounts for the instantaneous heat transfer coefficient. The Runge-Kutta algorithm is employed to solve the differential equations governing the engine's thermodynamic cycles. The research seeks to overcome the inherent limitations of traditional, costly, and time-consuming trial-and-error experimental approaches by leveraging advancements in computational speed and simulation capabilities.

Training UGV For Optimal Path Planning Using Reinforcement Learning
type: item
description: In the current era of artificial intelligence technology, unmanned ground vehicles (UGV) are increasingly being widely used in various fields due to the application of advanced technologies such as computer vision and reinforcement learning (RL). These technologies contribute to enhancing the level of automation, environmental awareness, and real-time flexible decision-making capabilities of UGVs. In this paper, we will apply RL with a decaying exploration rate strategy to train UGVs for path planning, obstacle avoidance, and optimal route discovery. Specifically, in the early stages of training, the exploration rate is set to a maximum value so that the agent can explore and collect more information of the state space; as the training time progresses, the exploration rate is gradually reduced, corresponding to a greater focus on the exploitation to find the optimal. Simulation results show that our proposal achieves faster convergence than RL in benchmark, demonstrating the effectiveness of this algorithm for real-world UGV applications.

Supervisor Incivility and Employees’ Customer-Directed Extra-Role Performance Among Airport Check-In Staff: The Mediating Role of Job Insecurity
type: item
description: Despite the growing body of research on workplace incivility, the specific relationship between supervisor incivility (SI) and employees’ customer-directed extra-role performance—as well as the underlying mechanisms—remains relatively underexplored. Drawing on the Transactional Model of Stress and Conservation of Resources (COR) theory, this study posits that job insecurity serves as a key cognitive mediator linking supervisor incivility to employees’ customer-directed extra-role performance. Empirical data were collected from airport check-in staff to test the proposed model. The findings reveal that SI has a significant negative impact on employees’ customer-directed extra-role performance. These results advance the workplace incivility literature by identifying a cognitive mechanism through which incivility undermines service behavior, and they offer practical implications for organizations aiming to enhance employee well-being and service quality

Difference Between Two Minima Normalized Min-Sum Algorithm For The LDPC Decoder
type: item
description: This study proposes the Difference Between Two Minima Normalized Min-Sum (DMNMS) algorithm for layered scheduling, which is suggested for implementing 5G New Radio Low-Density Parity-Check codes. The proposed algorithm aims to reduce memory space and enhance error correction performance. By applying modified factors to both variable nodes and check nodes processing, the DMNMS method goals to strengthen the protection ability for degree-1 variable nodes and compensate for the overestimation of extrinsic messages in Min-Sum-based algorithms. The suggested technique also used the difference between the first two minimum values and the first minimum among the input information, rather than compressing the check to variable messages to deliver the first two minima. Simulation data indicated that the proposed DMNMS algorithm performs better than the Normalized Min-Sum method, achieving up to 0.07 dB of decoding gain at a Bit Error Rate of 10⁻⁶ while using less memory.

Compute The Edge P-Laplacian Centrality For Air Traffic Network
type: item
description: The problem that we would like to solve in this paper is to compute the edge p-Laplacian centrality for the air traffic network. In this problem, instead of computing the edge p-Laplacian centrality directly which is the very hard problem, we convert the air traffic network to the line graph. Finally, we will compute the node p-Laplacian centrality of the line graph which is equivalent to the edge p-Laplacian of the air traffic network. In this paper, the novel un-normalized graph (p-) Laplacian based ranking method will be developed based on the un-normalized graph p-Laplacian operator definitions such as the curvature operator of graph (i.e. the un-normalized graph 1-Laplacian operator) and will be used to compute the node p-Laplacian centrality of the line graph. The results from the experiments show that the un-normalized graph p-Laplacian ranking methods can be implemented successfully.

Drivers of Digital Maturity in Emerging Markets: How Leadership and Innovation Shape SME Transformation
type: item
description: This study investigates how transformational leadership influences digital transformation (DT) in small and medium-sized enterprises (SMEs), with innovation acting as a mediating capability. Drawing on the Resource-Based View and Dynamic Capabilities Theory, we test a process-based model using survey data from 300 Vietnamese SMEs. Partial least squares structural equation modeling (PLS-SEM) confirms that leadership significantly predicts innovation (β = 0.582, p < .001), which in turn mediates its effect on digital maturity (indirect β = 0.244, p < .001). Complementary machine learning models (XGBoost R² = 0.772; RMSE = 0.597) identify innovation and leadership as the most influential predictors. These findings contribute theoretically by integrating RBV and DCT through a validated mediation mechanism and empirically by demonstrating the dual value of explanatory and predictive analytics. Practical implications call for SME leaders to foster innovation ecosystems and for policymakers to support leadership development as a strategic DT lever in emerging markets.

Re-Establishment Of Design Formula For Post-Buckling Shear Strength Of Practical Plate Girder
type: item
description: A plate web subjected to shear load is well-known for its capability to develop remarkable post-buckling shear strength when two pairs of boundary conditions of the web panel are provided sufficiently. So far, there are some theories and numerous idealizations to explain this behaviour. Still, all of the existing web post-buckling theories need to be revised, and thus, the elusive phenomena during the post-buckling stage remain a great challenge to researchers. By the finite element analysis results combined with the existing experimental shear tests, the previous paper (Mai TH et al, 2017) not only shed light on the weaknesses in the existing theories but also revealed new findings concerning the sources of the web post-buckling reserve. The current paper continuously conducted intensive investigations of the web post-buckling behaviour in the plate I-girders under shear load by a set of models, and the behaviour of intermediate transverse stiffeners was studied simultaneously. Consequently, the current results revealed that the boundary condition behaviour at the junction between transverse stiffeners and web panels depended primarily on the size of web panels (a/D). Next, a new design formula for ultimate shear strength in practical girders was proposed based on the observed results from the set of models. Finally, its accuracy was verified by 48 existing test specimens that possessed slight and moderate flanges.

Research On Applying Mplab Device Block For Simulink In Teaching Digital Control Systems
type: item
description: A low-cost rapid-prototyping system utilizing dsPIC microcontrollers, based on the MPLAB Device Blocks for Simulink development software, is introduced in this paper. This system provides an efficient and practical educational platform for students and researchers to understand and implement digital control systems in real time. By integrating Simulink with dsPIC, the system enables users to design, simulate, and deploy control algorithms without requiring extensive knowledge of embedded programming, thus bridging the gap between theoretical learning and practical implementation. The development software utilizes a graphical interface with block diagrams, allowing users to create control models easily. The real-time workshop (RTW) within Simulink generates optimized C code from these models, which is then automatically compiled, assembled, and downloaded onto the dsPIC microcontroller. This automation simplifies the entire process, eliminating the need for manual coding and debugging. The ability to implement real-time algorithms directly onto a hardware platform enhances the hands-on learning experience for students at both undergraduate and postgraduate levels. Clearly, this programming method is very useful for controllers of modern transportation vehicles such as drones and UAVs. Moreover, the system is cost-effective, making it accessible to educational institutions and small research labs. It supports a wide range of applications, including motor control, signal processing, and robotics, making it an invaluable tool for teaching and experimenting.

type: item
description: Purpose – This research explores the use of Virtual Reality (VR) technology as a sustainable and effective alternative to traditional ramp safety training methods in aviation. Research methodology – The study is conceptual in nature and based on an analytical review of current practices, emerging VR technologies, and their applications in aviation safety training. It evaluates the benefits and implications of VR through scenario-based simulations and case insights. Findings – VR allows aviation personnel to engage in realistic ramp safety simulations without exposure to actual hazards. It enhances training quality by enabling immersive and repeatable practice in high-risk scenarios. VR-based methods reduce the need for physical presence on the apron, thereby minimizing environmental impact and operational disruptions. The training process becomes more time-efficient and resource-conscious. Research limitations – As a conceptual study, this paper does not include empirical data from field trials or quantitative performance metrics. Further research is required to validate VR effectiveness through real-world implementation and user feedback. Practical implications – Implementing VR in ramp safety training can: • Improve safety outcomes for ground personnel. • Decrease training costs and time. • Support environmental sustainability by reducing apron access needs. • Align with industry trends toward digitalization and eco-friendly operations

The Influence Of Tiktok And Instagram Influencers On Gen Z Purchasing Behavior In Vietnam
type: item
description: This study investigates the impact of TikTok and Instagram influencers on the purchasing behavior of Generation Z (Gen Z) consumers in Vietnam, focusing on key influencer attributes: credibility, authenticity, entertainment value, and relatability. Distinguishing between micro- and macro-influencers, the research examines how these influencer types differently affect Gen Z’s purchasing intentions. Micro-influencers, with their smaller, highly engaged followings, are shown to foster stronger trust and relatability, whereas macro-influencers reach wider audiences but may lack the same depth of engagement. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), the findings reveal that all four influencer attributes significantly drive Gen Z’s purchasing intentions, with entertainment value emerging as the most influential factor. A purposive sampling method focusing on respondents born between 1997 and 2012 ensures the study’s relevance to Gen Z’s digital consumption patterns. These results provide practical insights for brands aiming to connect with Gen Z consumers through targeted influencer marketing strategies, emphasizing the need for authentic and engaging content on platforms frequented by this demographic

Factors Affecting The Knowledge Sharing Behavior Of Employees: A Case Of Import And Export Companies
type: item
description: Knowledge sharing is an extremely important factor for organizations and businesses, where knowledge is considered an intangible asset. Using a survey sample of employees from import-export companies in Ho Chi Minh City, Vietnam, this research investigated how these factors affect employees’ willingness to share knowledge in their daily work interactions. The results reveal that an innovative climate, perceived reciprocal benefits, and information technology have significant positive effects on knowledge-sharing behavior, while personality-based trust was not found to significantly influence knowledge sharing. These findings underscore the importance of fostering an environment that encourages innovation, mutual benefit, and effective use of technology to promote collaborative knowledge sharing. This study offers valuable contributions to both theory and practice by bridging the knowledge gap in the import-export sector and highlighting actionable strategies for enhancing knowledge-sharing behavior among employees
