Abstract
Purpose
This study aims to investigate the causes of leakage in radial oil seals under dynamic eccentricity, elucidate the influence of operating parameters on leakage failure and develop methods for predicting and preventing such leakage.
Design/methodology/approach
Based on the principle of cam motion and considering viscoelasticity, develops a motion model of the compression and release of the shaft seal and proposes a method to determine its failure. In addition, this study quantifies the leakage gap and formulates a quantitative calculation model to accurately determine the location and shape parameters of the leakage gap.
Findings
Leakage gaps predominantly occur during the release phase of the shaft seal. Their presence can be identified by comparing the descending times of the seal and the shaft during this phase. An increase in rotation speed and eccentricity heightens the likelihood of gap formation, with both the dimensions and leakage rate of the gap increasing as these factors escalate. Eccentricity, in particular, has a more pronounced effect on gap formation.
Originality/value
This study clarifies the failure mechanisms of radial oil seals under dynamic eccentricity and introduces a criterion for identifying leakage gaps, providing valuable theoretical guidance for the design and optimization of radial oil seals.

Abstract
Purpose
Work-study programmes aim to support young adults transitioning from tertiary education to work and contribute to enhancing their employability. The purpose of this study is to provide a detailed analysis of the learning experiences of trainees in work-study programmes within the broad field of engineering.
Design/methodology/approach
The data gathering procedures used interviews with participants of a specific work-study programme and conducting thematic analyses to identify and understand the motivations of these adults for enrolling in work-study programmes and their associated workplace learning experiences. Fifty-two alumni of electrical and logistics engineering programmes completed 12 months of a separate work-study programme and consented to participate in an hour-long interview. They elaborated upon their work-learn experiences to explicate their work-learn needs and challenges in those interviews.
Findings
Findings include workplaces facilitated skills development through providing combinations of work tasks comprising both routine and novel work assignments; challenging circumstances at the workplace provided trainees with opportunities to develop adaptive capacities; and engaging in non-routine work processes fosters integration into the engineering workplace community.
Originality/value
The findings contribute to the existing literature by exemplifying how routine engineering activities are practical affordances through which engineering trainees construct knowledge and dispositions for engaging in challenging, non-routine engineering work. Such experiences are crucial in preparing trainees for advanced roles in logistics or electronic sectors.

Abstract
Purpose
The purpose of this study is to investigate the connections between the regulatory governance, human capital, stakeholder orientation, management control systems (MCSs) and sustainable performance (SP) of power companies. The authors especially looked at how much regulatory governance, human capital, stakeholder orientation and MCSs affect the SP across power companies in Uganda.
Design/methodology/approach
This is a cross-sectional and correlational study. Data were collected from 105 power companies using a questionnaire and analysed using SPSS.
Findings
Stakeholder orientation, MCSs, human capital and regulatory governance significantly predict variances in the SP of power providers in Uganda. Stakeholder orientation is the most important predictor of SP of power companies.
Research limitations/implications
The absence of validation from important stakeholders and the major reliance on company-provided data in existing research on SP raises the possibility of self-desirability bias. To evaluate and verify the information supplied by firms with external stakeholders, further studies might consider using an explanatory mixed methods technique, in which quantitative data are initially gathered from the managers of power companies and analysed and then validated by interviews with important stakeholders.
Originality/value
Using stakeholder, legitimacy and resource-based theories has provided a better explanation for SP which is a multi-dimensional notion. Moreover, the study adds to the body of perception-based research that offers direct management incentives for SP. The perspectives of managers have been gathered through the use of self-administered questionnaires to gather impressions of managers of businesses, which has helped to tap into all aspects of SP. The study’s results offer, probably for the first time to the best of the authors’ knowledge, evidence of the contextual elements that affect SP in African nations like Uganda particularly in the power sector.

Abstract
Purpose
This study aims to evaluate healthcare practitioners’ perceptions of electronic health record (EHR) systems and their effectiveness in supporting clinical decision-making in Tanzanian Primary Healthcare (PHC) facilities.
Design/methodology/approach
A mixed-methods approach was employed, combining quantitative data from structured questionnaires and qualitative insights from open-ended responses. The study was conducted in the Dodoma region of Tanzania, focusing on a diverse representation of PHC facilities, including district hospitals, health centres and dispensaries. Data were analysed using multiple linear regression for quantitative data, and thematic analysis was applied to qualitative responses.
Findings
The results revealed that while EHR systems are widely used in Tanzanian PHC facilities, their impact on clinical decision-making remains limited. Only a moderate portion of practitioners perceived EHR systems as effective in decision support, and frequent system use was negatively correlated with user satisfaction. Challenges such as inadequate training and support, system crashes, slow performance and poor usability and integration into clinical workflows were significant barriers to effectively utilising EHR systems.
Originality/value
This study contributes to the limited literature on EHR system implementation in low-resource settings, specifically Tanzania, by focusing on decision-support features within EHR systems. The findings offer valuable insights for healthcare policymakers, system designers and practitioners to optimise EHR implementation and improve healthcare outcomes in resource-constrained environments.

Abstract
It is important to understand how recent regulation allowing small businesses to issue equity through crowdfunding can impact investors' decision-making. One unique feature of crowdfunding presented to investors is an issuer's fundraising goal (i.e., minimum target) and how much money has currently been pledged toward that goal by other investors. However, it is unknown whether investors are sensitive to the level at which the minimum target is set, which can influence the perception of the level of support an investment has received from other investors. While holding the amount of capital pledged to an issuer constant, we conduct an experiment to examine how the minimum level of an issuer's fundraising goal impacts the likelihood of investment by investors. We predict that lower minimum goals will facilitate a perception that an issuer has strong support from other investors and will lead to a change in how investors perceive that issuer. We find that, regardless of the financial strength of the issuer, lower minimum fundraising goals lead to greater investment likelihood compared to higher minimum fundraising goals. We also find that issuers with weak financial strength tend to benefit from this effect more than stronger firms. Finally, this effect is mediated by investors' perceptions of the support of other investors in the company. The results of our study have both practical and theoretical contributions.

Abstract
As the today's world is leading toward the digital dependency and after the world pandemic of COVID-19, the dependency of students and the university is completely through a digital medium, in context with that the higher education according to the demand of the generation is leading towards digital transformation. The digital transformation in the sector of education is the road map for the sustainable management and development of education. The digital transformation is the new pillar of education in which the students are mostly reliable. The digitalization in the field of education will lead to simple and clarified as well as multiple way for acquiring the knowledge. As the integration of the new model of education system is applied and implemented throughout the globe, the digital medium plays a significant role for the smooth and the systemic development of the model. In this chapter, the pathway for the development of the well-stable and well-developed strategies is considered in which the integration of the essential requirements, proper guidance, and advantages of the model is dependent for the transformation to digital medium of the higher education that will be leading to the development of the management and the education system. The foundation of that transformation model is detailed in the paper for the digitalization of higher education.

Abstract
Purpose
The purpose of this study is to use a lifetime income measure to evaluate the long-run housing affordability for an understudied cohort of households in the literature – the millennials. The authors do this in the context of Malaysia, measuring long-run affordability for four housing types across geographic locations and income distributions.
Design/methodology/approach
This study calculates a long-run housing affordability index (HAI) using data on house prices and household incomes. Essentially a ratio of predicted lifetime incomes to house prices, the HAI is computed for four common housing types in Malaysia from 2005 to 2016 and for six states in the country. The HAI is also compared across four income percentiles.
Findings
The analysis reveals varying patterns of housing affordability among different states in Malaysia. Housing affordability has declined since 2010, with most housing types being unaffordable for millennial-led households with the lowest income. Housing is most affordable for those in the highest income bracket, although even here, there are pockets of unaffordable housing as well.
Practical implications
Based on the findings, this study proposes three targeted interventions to improve housing affordability for Malaysian millennials.
Originality/value
This study fills a gap in the literature by examining the long-run housing affordability of Malaysian millennial-led households based on both geographic location and income distribution. The millennial population is understudied in the housing affordability literature, making this study a valuable contribution to the field.

This study aims to examine the mediating role of trainer preparation in the effect employee trainer self-efficacy has on trainer performance.
Abstract
Purpose
This study aims to examine the mediating role of trainer preparation in the effect employee trainer self-efficacy has on trainer performance.
Design/methodology/approach
Using a census, data was collected from internal employee trainers in two universities in Ghana. In testing the hypotheses, a structural equation modelling based on 10,000 bootstrap samples was used, and the BCa confidence intervals were used to establish the significance of the hypotheses.
Findings
This study revealed trainer preparation as a complementary partial mediator in the effect trainee engagement self-efficacy and instruction self-efficacy had on trainer performance. In addition, the importance–performance map analyses demonstrated that the factor with the most importance in the model was instruction self-efficacy, yet it was not the highest-performing factor.
Originality/value
This study highlights the mediating role played by preparation in the effect of trainer self-efficacy on trainer performance. In addition, it adds to the dearth of studies that focus on employee trainers while at the same time using data from the trainers themselves.

Abstract
Purpose
Despite the burgeoning popularity of virtual gifting in live streaming, research lacks an in-depth understanding of the drivers behind this behavior. Using para-social relationship (PSR), this study aims to capture viewers’ lively social feelings toward the streamer as the key factor leading to the purchase behavior of virtual gifts. It also aims to establish a theoretical link between PSR and viewers’ holistic experience in live streaming as captured by cognitive absorption and aims to investigates the role of technological features (i.e. viewer–streamer and viewer–viewer interactivity, streamer-level and viewer-level deep profiling and design aesthetics) in shaping viewers’ experience.
Design/methodology/approach
Based on 433 survey responses, this study employs a combination of structural equation modeling and neural networks to offer valuable insights into the relationships between the technological environment, viewer experience and viewer behavior.
Findings
Our results highlight the salience of PSR in promoting the purchase of virtual gifts through cognitive absorption and the importance of the technological environment in eliciting the viewer experience. This study sheds light on the development of PSR in a technological environment and its relationship with cognitive absorption.
Originality/value
By applying PSR to conceptualize viewers’ perceived connection with the streamer, this study extends the research on purchase behavior in the non-shopping context by providing an enlightened understanding of virtual gift purchase behavior in live streaming. Moreover, by theoretically linking PSR with cognitive absorption, virtual gift purchase and technological features of live streaming, it enriches the theory of PSR and bridges the gap between the design practice of supporting the IT infrastructure of live streaming and research.
