Japan's success in the management of its organisations has long been admired and envied by the rest of the western world. An early “manager” is examined and his example upheld as one of the first exponents of Japanese management practice.

The purpose of this paper is to analyse the short-term wealth effects of mergers and acquisitions (M & As) in Malaysia. In addition, this study also examines the factors that affect the short-term shareholders’ wealth during M & A announcements in Malaysia.

The short-term wealth effect is measured by the Cumulative Average Abnormal Returns (CAARs). For the purpose of this study, the wealth effects of a sample of 180 target and 196 bidding companies announced in Malaysia during the period from 2001 to 2009 are analyzed.

Results of the study revealed that there are positive market reactions by both target and bidding shareholders towards M & A announcements. However, target shareholders earned significantly higher CAARs than bidding shareholders. There is sufficient evidence to suggest that economic condition surrounding merger announcements, type of acquisition (diversified/related), premium paid and status of bid (successful/failed) affect the short-term wealth effects of target and bidding shareholders during M & A announcements. However, the impact on the target and bidding shareholders are different. Relative size negatively affects bidding shareholders’ wealth. Target with higher ROE also earned significantly higher returns.

There is high number of announced M & A deals in Malaysia, little is known about the determinants of short-term wealth effects of M & As in emerging market Malaysia, in particular the third M & A wave.

Japan's adoption (and adaption) of QC circles 10 years earlier than most of the rest of the world, and the role this has played in Japan's advancement as an industrialised nation, is examined. The growth of circles in Japan is charted, and a consideration is given of the implementation of QC circles in other Far Eastern countries, South America, Europe and the US. Training at various levels, to overcome the shortage of qualified people, is discussed. A comparison is made between QC circles and other more conventional motivational plans, and five main issues are analysed; a comparison is also made between Japanese and Western industry and their respective worker attitudes. The necessity for QC circles to become established in the US, and considered a fundamental human resource enhancement, rather than a foolish fad, is stated.

In this paper, experimental and numerical results of a lambda wing have been compared. The purpose of this paper is to study the behaviour of lambda wings using a CFD tool and to consider different numerical models to obtain the most accurate results. As far as the consideration of numerical methods is concerned, the main focus is on the evaluation of computational methods for an accurate prediction of contingent leading edge vortices’ path and the flow separation occurring because of the burst of these vortices on the wing.

Experimental tests are performed in a closed-circuit wind tunnel at the Reynolds number of 6 × 105 and angles of attack (AOA) ranging from 0 to 10 degrees. Investigated turbulence models in this study are Reynolds Averaged Navior–Stokes (RANS) models in a steady state. To compare the accuracy of the turbulence models with respect to experimental results, sensitivity study of these models has been plotted in bar charts.

The results illustrate that the leading edge vortex on this lambda wing is unstable and disappears soon. The effect of this disappearance is obvious by an increase in local drag coefficient in the junction of inner and outer wings. Streamlines on the upper surface of the wing show that at AOA higher than 8 degrees, the absence of an intense leading edge vortex leads to a local flow separation on the outer wing and a reverse in the flow.

Results obtained from the behaviour study of transition (TSS) turbulence model are more compatible with experimental findings. This model predicts the drag coefficient of the wing with the highest accuracy. Of all considered turbulence models, the Spalart model was not able to accurately predict the non-linearity of drag and pitching moment coefficients. Except for the TSS turbulence model, all other models are unable to predict the aerodynamic coefficients corresponding to AOA higher than 10 degrees.

The presented results in this paper include lift, drag and pitching moment coefficients in various AOA and also the distribution of aerodynamic coefficients along the span.

The purpose of this study is to the modeling of the dielectric barrier discharge (DBD) actuator on the Eppler 387 (E387) airfoil in low Reynolds number conditions.

A validated direct-forcing immersed boundary method is used to solve the governing equations. A linear electric field model is used to simulate the DBD actuator. A ray-casting technique is used to define the geometry.

The purposed model is validated against the former studies. Next, the drag and lift coefficients in the static stall of the E387 airfoil are investigated. Results show that when the DBD actuator is on, both of the coefficients are increased. The effects of the location, applied voltage and applied frequency are also studied and find that the leading-edge actuator with higher voltage and frequency has better improvement in the forces. Finally, the dynamic stall of the E387 with the DBD actuator is considered. The simulation shows that generally when the DBD is on, the lift coefficient in the pitch-up section has lower values and in the pitch-down has higher values than the DBD off mode.

It is demonstrated that using the DBD actuator on E387 in the low Reynolds number condition can increase the lift and drag forces. Therefore, the application of the airfoil must be considered.

The results show that sometimes the DBD actuator has different effects on E387 airfoil in low Reynolds number mode than the general understanding of this tool.

This study investigates work and non-work antecedents for the work–life balance (WLB) development of remote employees during the COVID-19 pandemic. Longitudinal data (N = 1,146, T1; N = 737, T2) was collected in May–June 2020 and December 2020 in one multinational company (MNC) in Finland. In data analysis, structural equation modeling (SEM) with a cross-lagged panel model was utilized. The results revealed that during the pandemic, WLB slightly decreased. The quantitative job demands increased and predicted a decreased WLB at T2. Job autonomy decreased but did not have an effect on WLB development or buffer the negative effect of quantitative job demands on WLB. Time saved from commuting was positively related to WLB development, but the number of children living at home and the age of the youngest child had no statistically significant link to WLB development over time (similar finding for men and women). Although care responsibilities from the gender perspective is not the focus of our study, the additional analysis show that WLB at T1 was more challenging for women the more children they had, or the younger the youngest child was. For men, children did not make a difference for their WLB at T1. This finding indicates that WLB has been more challenging for mothers compared to fathers already when our first data had been collected, and the continuance of the pandemic did not change the situation in any direction. This research contributes to the knowledge about work and non-work related demands and resources as antecedents for WLB development during the pandemic. As a practical implication during the pandemic, the authors suggest that employers should follow development for employees’ WLB as a measure of well-being in remote work. In addition, the workload of remote employees should be followed, and time saved from commuting should be preserved as employees’ non-work time and protected from work-related tasks.

This study investigates the coupling effects between temperature, permeability and stress fields during the development of geothermal reservoirs, comparing the impacts of inter-well pressure differentials, reservoir temperature and heat extraction fluid on geothermal extraction.

This study employs theoretical analysis and numerical simulation to explore the coupling mechanisms of temperature, permeability and stress fields in a geothermal reservoir using a thermal-hydrological-mechanical (THM) three-field coupling model.

The results reveal that the pressure differential between wells significantly impacts geothermal extraction capacity, with SC-CO2 achieving 1.83 times the capacity of water. Increasing the aperture of hydraulic and natural fractures effectively enhances geothermal production, with a notable enhancement for natural fractures.

The research provides a critical theoretical foundation for understanding THM coupling mechanisms in geothermal extraction, supporting the optimization of geothermal resource development and utilization.

Designing technologies for active and healthy ageing (AHA) requires a subtle understanding of end users (primary stakeholders) and healthcare professionals (secondary stakeholders). Often, their perspectives can be heterogeneous and contradictory. Identifying and negotiating them may be a challenge for designers. The purpose of this paper is to present our approach to understanding and negotiating contradictory stakeholder perspectives when designing AHA technologies for older adults.

The authors conducted an exploratory interview study with 15 community-dwelling older adults and 11 healthcare stakeholders, including doctors, health insurance agencies, policymakers and caregivers. The authors analyzed the interview material and negotiated contradictory perspectives.

Three major issues among stakeholders emerged: perspectives on AHA; perceived benefits and drawbacks of AHA technologies; and concerns about data privacy, control and trust.

The results show the heterogeneity and contradictions in stakeholder perspectives on AHA technologies and how these perspectives may be negotiated. This could help understand and facilitate long-term use of AHA technologies among older adults.

This study alerts researchers to contradictory perspectives among older people and healthcare stakeholders and the importance of involving them in the design of AHA technologies.

This study aims to provide a practical strategy for customer service and salesforce from the basis of behavioral economics. When customers thought they missed a discount but eventually could get the deal, they perceived that they had obtained more value. This research defines such a conversion effect between gain and loss accounts, demonstrates its impact in marketing settings and provides the salesforce a tactic to increase sales and quality of customer service to improve the consumer experience in the social customer journey.

Three experiments were conducted in a behavioral lab and online setting. Participants were randomly assigned to 2 (gain vs loss) × 2 (converted vs simple) between-subjects designs in the first two experiments and 2 (gain vs loss) × 2 (converted vs simple) × 2 (high price vs low price) in the third experiment. Analysis of variance was conducted to analyze the data. Mediation and moderation analyses were also conducted to identify the mediator and moderator in the model.

The conversion between gain and loss mental accounts exists, and the converted gains are more likely to lead consumers to make purchases with a once-lost discount than simple gains. This conversion effect is mediated by consumers’ implemental mindset activated by the conversion and moderated by price.

This research shows that mental accounts of gains and losses can be dynamically converted to one another. It provides a managerial tactic for salesforces and customer service to lead consumers to make a purchase decision right away. This is especially important when they aim to enhance the consumer experience in the social customer journey.
