Abstract
Purpose
Inspired by the dynamic changes in our daily lives enabled via quantified-self technologies and the urgent need for more studies on the human-computer interaction design mechanisms adopted by these applications, this study explores the value of user affective experience mirroring and examines the empowerment effect of meaningful gamification in a psychological self-help system (PSS) that aids people in work stress relief.
Design/methodology/approach
Based on an analysis of the existing systems and theories in relevant fields, we conducted mixed-method research, involving semi-structured interviews, experience sampling experiments and user bio data triangulations, to identify the benefits of user affective experience mirroring and examine the impact of visual impact metaphor–based (VIM) meaningful gamification on PSS users.
Findings
For a gamified PSS, users generally perceive VIM as arousing more feelings of enjoyment, empathy, trust and usefulness, empowering them to gain more mastery and control over their emotional well-beings, especially with relieving their occupational stress and upbringing their level of perceived happiness. Overtime, VIM-based meaningful gamification further boosts such value of a PSS.
Research limitations/implications
Weaving together meaningful gamification and psychological empowerment theories, the results emphasized that successful empowerment of user through gamification in PSSs relies heavily on whether a deeper and meaningful affective connection can be established with the users, in short, “meaningful gamification for psychological empowerment”. Such an understanding, as demonstrated in our research framework, also sheds light on the design theories for persuasive technology and human influence tactics during human computer interactions.
Practical implications
The results of the study demonstrate to practitioners how to make the best use of gamification strategies to deeply relate to and resonate with users. Even without complicated game-play design, meaningful gamification mechanisms, such as VIM facilitate the empowerment of users while gaining their appreciation, establishing a deeper connection with them and eventually generating persuasive effects on intended future behavioural outcomes.
Social implications
The effective management of work-related stress with handy tools such as a VIM-based PSS can be beneficial for many organizations and, to a large extent, the society.
Originality/value
This study proposed and empirically demonstrated the empowerment effect of meaningful gamification for PSS users. In this cross-disciplinary study, theories from different research domains were synthesized to develop a more thorough and multi-faceted understanding of the optimal design strategies for emerging information systems like this VIM-based PSS.

Abstract
Purpose
The purpose of this paper is to introduce a value improvement model (VIM) for repetitive processes applicable to any business where people and/or plant provide a service to support the overall business objective. Arguing competitive advantage can be realised through different amalgams of productive and strategic resources, the VIM introduced focuses on aligning resource bundles and influencing factors creating efficacious, efficient and effective processes by applying Lean thinking and Six Sigma tools and techniques more holistically.
Design/methodology/approach
The research methodology taken incorporated a case study approach complimented by the action research process of planning, observing and reflecting summarized as an action case study research design. The case study data examine the development of a management cycle of value improvement on an inter‐terminal shuttle transportation system within a busy international airport.
Findings
The VIM has been proven as a useful model for understanding the critical inputs and influencing factors for delivering sustainable improvements to repetitive processes in a service industry environment.
Research limitations/implications
The research was completed in situ at a single business using a single case study example to develop and test the conceptual framework. The VIM would therefore benefit from being applied in both manufacturing and service industry environments to identify other potential environmental factors influencing the repetitive processes, increasing the usefulness to other potential users.
Originality/value
This research project has developed a visual and systematic framework that enables managers to understand, assess and improve repetitive processes within their businesses. The case study example presented in the paper show how this framework can be applied to the setting up of value improvement management cycles.

Abstract
Purpose
The purpose of this paper is to implement variational iteration method (VIM) and homotopy perturbation method (HPM) to solve modified Camassa‐Holm (mCH) and modified Degasperis‐Procesi (mDP) equations.
Design/methodology/approach
Perturbation method is a traditional method depending on a small parameter which is difficult to be found for real‐life nonlinear problems. To overcome the difficulties and limitations of the above method, two new ones have recently been introduced by He, i.e. VIM and HPM. In this paper, mCH and mDP equations are solved through these methods.
Findings
To assess the accuracy of the solutions, the comparison of the obtained results with the exact solutions reveals that both methods are tremendously effective.
Originality/value
The paper shows that VIM and HPM can be implemented to solve mCH and mDP equations.

Abstract
Purpose
A previous attempt to implement the use of historical measures of asset management effectiveness – as part of a value improvement model (VIM) for repetitive processes – had not been 100 percent successful within an airport operational engineering environment. Taking into account the more holistic approach realised through applying a soft systems methodology (SSM), the purpose of this paper was to use the CATWOE (Customers, Actors, Transaction, World View, Owner and Environment) tool to gain an understanding of the root definition of the problem statement developing a conceptual model used to facilitate an improvement to the implementation process.
Design/methodology/approach
The research methodology taken incorporated an action research approach combining case study research with an action research process of planning, observing and reflecting summarized as taking an action case research design.
Findings
This research has developed a visual and systematic framework that enables managers to understand, analyse and improve value in their asset management repetitive processes. The CATWOE root definition tool has been used to create a conceptual model of the problem area providing a holistic view of the stakeholders and the internal and external environmental constraints that the VIM for asset management sits within.
Research limitations/implications
The research was completed in‐situ at a single airport focused on a single group of assets managed by a single group of stakeholders. Future research should look to further develop the VIM and CATWOE approach in other asset management environments such as manufacturing as well as asset intensive service industries.
Originality/value
This research has taken a soft systems approach and successfully applied it to the implementation of hard systems measurements of asset management effectiveness within an airport operational engineering environment. Other managers with asset management responsibilities will find this approach useful in achieving their core objective to improve the effectiveness and efficiency of their assets and the teams employed to maintain them at minimal total cost.

Abstract
ROLLING‐element bearings for aircraft turbine engine mainshaft applications are generally specified to be made of AISI M‐50 steel. Current aircraft turbine engine manufacturers' material specifications require a double vacuum melted (VIM‐VAR, for vacuum induction melt, vacuum arc smelt) AISI M‐50 steel for mainshaft bearings. With this material, ball bearing fatigue lives of nearly 100 times AFBMA predicted life have been obtained. Reduction in inclusion content, trace elements, and interstitial gas content is considered responsible for a major portion of this life advancement. AISI M‐50 also has the hot hardness and hardness retention ability for long‐life rolling‐element bearing operation at temperatures up to 588 K (600°F).
