Abstract
Purpose
Recent advancements in Artificial Intelligence (AI) and, at its core, Machine Learning (ML) offer opportunities for organizations to develop new or enhance existing capabilities. Despite the endless possibilities, organizations face operational challenges in harvesting the value of ML-based capabilities (MLbC), and current research has yet to explicate these challenges and theorize their remedies. To bridge the gap, this study explored the current practices to propose a systematic way of orchestrating MLbC development, which is an extension of ongoing digitalization of organizations.
Design/methodology/approach
Data were collected from Finland's Artificial Intelligence Accelerator (FAIA) and complemented by follow-up interviews with experts outside FAIA in Europe, China and the United States over four years. Data were analyzed through open coding, thematic analysis and cross-comparison to develop a comprehensive understanding of the MLbC development process.
Findings
The analysis identified the main components of MLbC development, its three phases (development, release and operation) and two major MLbC development challenges: Temporal Complexity and Context Sensitivity. The study then introduced Fostering Temporal Congruence and Cultivating Organizational Meta-learning as strategic practices addressing these challenges.
Originality/value
This study offers a better theoretical explanation for the MLbC development process beyond MLOps (Machine Learning Operations) and its hindrances. It also proposes a practical way to align ML-based applications with business needs while accounting for their structural limitations. Beyond the MLbC context, this study offers a strategic framework that can be adapted for different cases of digital transformation that include automation and augmentation of work.

Abstract
Purpose
The ideal self has had a place in management literature in recent years with reference to identity and role change. However, except for a JMD article in 2006, there has been little theorizing on the ideal self, which is often treated as a static construct. The purpose of this article is to update and refine the concept and explain the dynamic nature of the construct.
Design/methodology/approach
This conceptual paper is based on a review of the recent management and psychology literature related to the ideal self and its components.
Findings
The authors propose a dynamic theory of the emerging ideal self and delineate how its components evolve over time.
Research limitations/implications
The ideal self, or one's personal vision, is a major motivator of learning and change and the sustainability of such efforts. The time dynamic theory would encourage and guide longitudinal research using better variables and measures as well as help in conceptualizing the role of socialization, social identity and life/career stages.
Practical implications
With a better theory of the ideal self, trainers, consultants, coaches and teachers can help people update their deep sense of purpose and the sustaining driver of learning and change the ideal self. It could help people and organizations address a major determinant of engagement.
Originality/value
This theory offers a temporal understanding of how the ideal self can motivate learning and change at different life and career eras, which can help in designing future research on identity-related transitions.

Abstract
Purpose
The purpose of this study is to develop an optimization method for charging plans with the implementation of time-of-day (TOD) electricity tariff, to reduce electricity bill.
Design/methodology/approach
Two optimization models for charging plans respectively with fixed and stochastic trip travel times are developed, to minimize the electricity costs of daily operation of an electric bus. The charging time is taken as the optimization variable. The TOD electricity tariff is considered, and the energy consumption model is developed based on real operation data. An optimal charging plan provides charging times at bus idle times in operation hours during the whole day (charging time is 0 if the bus is not get charged at idle time) which ensure the regular operation of every trip served by this bus.
Findings
The electricity costs of the bus route can be reduced by applying the optimal charging plans.
Originality/value
This paper produces a viable option for transit agencies to reduce their operation costs.

Abstract
Purpose
This paper aims to study followers' proactive personality (PP) as a personal resource in moderating the hindering impact of exploitative leadership (EL) on followers' job strain (JS).
Design/methodology/approach
Self-report data on EL, JS and PP were obtained from 113 working students in the USA, and a cross-sectional design was used. The data was analyzed using SPSS 27 through hierarchal multiple regression and the PROCESS macro.
Findings
The findings support the buffering role of PP on the hindering impact of EL on JS, such that followers with higher PP tend to buffer the positive relationship between EL and followers' JS.
Practical implications
This study recommends practitioners to hire proactive individuals and/or enable existing employees to engage in proactivity in the presence of exploitative leaders to better cope with their self-serving behaviors.
Originality/value
Using the conservation of resources (COR) theory, this study is the first to use PP as a personal resource that protects against and mitigates the negative impact of EL.

Abstract
Purpose
The electromechanical brake system is leading the latest development trend in railway braking technology. The tolerance stack-up generated during the assembly and production process catalyzes the slight geometric dimensioning and tolerancing between the motor stator and rotor inside the electromechanical cylinder. The tolerance leads to imprecise brake control, so it is necessary to diagnose the fault of the motor in the fully assembled electromechanical brake system. This paper aims to present improved variational mode decomposition (VMD) algorithm, which endeavors to elucidate and push the boundaries of mechanical synchronicity problems within the realm of the electromechanical brake system.
Design/methodology/approach
The VMD algorithm plays a pivotal role in the preliminary phase, employing mode decomposition techniques to decompose the motor speed signals. Afterward, the error energy algorithm precision is utilized to extract abnormal features, leveraging the practical intrinsic mode functions, eliminating extraneous noise and enhancing the signal’s fidelity. This refined signal then becomes the basis for fault analysis. In the analytical step, the cepstrum is employed to calculate the formant and envelope of the reconstructed signal. By scrutinizing the formant and envelope, the fault point within the electromechanical brake system is precisely identified, contributing to a sophisticated and accurate fault diagnosis.
Findings
This paper innovatively uses the VMD algorithm for the modal decomposition of electromechanical brake (EMB) motor speed signals and combines it with the error energy algorithm to achieve abnormal feature extraction. The signal is reconstructed according to the effective intrinsic mode functions (IMFS) component of removing noise, and the formant and envelope are calculated by cepstrum to locate the fault point. Experiments show that the empirical mode decomposition (EMD) algorithm can effectively decompose the original speed signal. After feature extraction, signal enhancement and fault identification, the motor mechanical fault point can be accurately located. This fault diagnosis method is an effective fault diagnosis algorithm suitable for EMB systems.
Originality/value
By using this improved VMD algorithm, the electromechanical brake system can precisely identify the rotational anomaly of the motor. This method can offer an online diagnosis analysis function during operation and contribute to an automated factory inspection strategy while parts are assembled. Compared with the conventional motor diagnosis method, this improved VMD algorithm can eliminate the need for additional acceleration sensors and save hardware costs. Moreover, the accumulation of online detection functions helps improve the reliability of train electromechanical braking systems.
