Abstract
Purpose
Employee’s lying behavior has become ubiquitous at work, and managers are keen to know what can be done to curb such behavior. Managers often apply anti-lying strategies in their management and, in particular, the role of self-awareness on lying intervention has drawn academic attention recently. Drawing on multi-disciplinary literature, this study aims to investigate the efficacy of self-awareness in reducing lying behavior.
Design/methodology/approach
Following the perspectives of positivism and deductive reasoning, a quasi-experimental research approach was adopted. Employees from Dijon, France were recruited as research participants. Based on the literature, different conditions (scenario manipulation) were designed and implemented in the laboratory, in which participants were exposed to pre-set lying opportunities and their responses were analyzed accordingly.
Findings
Unlike prior studies which praised the merits of self-awareness, the authors found that self-awareness did not decrease lying behavior, not encouraging the confession of lying either. Employees actually lied more when they believed other employees were lying.
Practical implications
This study suggests managers not to rely on employee’s self-awareness; rather, the concept of self-awareness should be incorporated into the work ethics, and managers should schedule regular workshops to keep employees informed of the importance of ethics. When employees are regularly reminded of the ethics and appreciate its importance, their intention of lying is more likely to decrease.
Originality/value
To the best of the atuhors’ knowledge, the current research is the first in its kind to investigate lying intervention of employees in the laboratory setting. Research findings have brought new insights into the lying intervention literature, which has important implication on the implementation of anti-lying strategies.

Abstract
Purpose
The purpose of this paper is to approach women's entrepreneurship from a social psychological perspective, with the aim of contributing to a better understanding of the entrepreneurial phenomena and to its development as a field of research.
Design/methodology/approach
The gender aspect of entrepreneurship is essentially socio‐psychological in nature. First, the authors define the social psychology research scope and present a selection of social psychology theories that are particularly relevant to the domain of women's entrepreneurship. Concepts such as stereotypes, stereotype threat and role models are introduced. Second, the authors instantiate how the social psychology experimental method can address core questions in the women's entrepreneurship field, such as women's under‐representation in entrepreneurial positions.
Findings
The conclusion of this paper is twofold: on the one hand, social psychology theories can address crucial issues in women's entrepreneurship and on the other hand, experimentation as a research methodology enables us to determine causal relationships. However, given the specificities of both social psychology and women's entrepreneurship, we strongly recommend collaborative research between researchers in the two areas.
Research limitations/implications
The authors propose concrete though non‐exhaustive areas of study in women's entrepreneurship research, where social psychological theories can be successfully employed.
Social implications
Using applied social psychology research, the authors suggest practical ways to reject negative stereotypes that prevent women from being entrepreneurs.
Originality/value
Although women's entrepreneurship is a social psychological phenomenon, this field of study still rarely makes reference to social psychology as a discipline for theorizing the relationship between gender and entrepreneurship.

Abstract
Purpose
The purpose of this paper is to analyse employees’ lying behaviour and its findings have important implication for the management and prevention strategies of lying in the workplace. Employee lying has caused both reputational and financial damage to employers, organisations and public authorities. This study adopts a psycho-cognitive perspective to examine the mechanism of lying reduction and the influence envy has on lying behaviour.
Design/methodology/approach
Incorporating social comparison phenomenon and cognate studies this study suggests that envy may restrain people from lying in the workplace. Specific hypotheses are developed and tested with 271 participants using dice game scenarios.
Findings
Research findings have found that people are likely to lie if lying brings them benefits. However, the findings also reveal that the envy aroused between two people may act as a psychological barrier to reduce the tendency to lie.
Originality/value
The research findings have provided an alternative perspective to the current prevailing view of envy as a negative emotion. Envy need not always be negative. Envy can provide an internal drive for people to work harder and enhance themselves but it can also act as a brake mechanism and self-regulator to reduce lying, and thereby has a potentially positive value.

Abstract
Purpose
The paper aims to present a numerical modeling procedure for the analysis of liquid sloshing in a flexible tank subjected to an external excitation, with taking into account the effects of fluid–structure interaction (FSI).
Design/methodology/approach
A numerical model based on coupling a two-phase flow solver and an elastic solid solver is developed in OpenFOAM code. The Arbitrary Lagrangian–Eulerian formulation is adopted for the two-phase Navier–Stokes equations in a moving domain. The volume of fluid (VOF) method is applied for the air–liquid interface tracking. The finite volume method is used for the spatial discretization of both the fluid and the structure dynamics equations. The FSI coupling problem is solved by an explicit coupling scheme. The model is validated for linear and nonlinear sloshing cases. Then, it is used to analyze the effects of the liquid sloshing on the dynamic response of the tank and the effects of the tank flexibility on the liquid sloshing.
Findings
The obtained results show that the flexibility of the tank walls amplifies the amplitude of the sloshing and increases the fluctuation period of the air–liquid interface. Furthermore, it is found that the bending moment acting on the tank walls may be underestimated when rigid walls assumption is adopted as usually done in sloshing tank modeling. Also, tank walls flexibility causes a phase shift in the free surface dynamic response.
Originality/value
A review of previous studies on liquid sloshing in flexible tanks revealed that FSI effects have not been clearly and comprehensively analyzed for large-amplitude liquid sloshing. Many physical and numerical aspects of this problem still require clarifications and enhancements. The added value of the present work and its originality lie in the investigation of large-amplitude liquid sloshing in flexible tanks by using a staggered coupling approach. This approach is carried out by an original combination of a linear solid solver with a two phase fluid solver in OpenFOAM code. In addition, FSI effects on some response quantities, identified and analyzed herein, have not been found in the previous works.

Abstract
Purpose
In Laser Power Bed Fusion (LPBF), the process and operating parameters influence the mechanical and geometrical characteristics of the manufactured parts. Therefore, the optimization and control of these parameters are mandatory to improve the quality of the produced parts. During manufacturing, the process parameters are usually constant whatever the part size or the built layer. With such settings, the manufacturing process may lead to an inhomogeneous thermal behavior and locally overheating areas, impacting the part quality. The aim of this study is to take advantage of an analytical thermal model to modulate the laser power upstream of manufacturing.
Design/methodology/approach
The approach takes place in two steps: the first step consists in calculating the preheating temperature at the considered point and the second one determines the power modulation of the laser to reach the desired temperature at this point.
Findings
Numerical investigations on several use cases show the effectiveness of the method to control the overheated areas and to homogenize the simulated temperature distribution.
Originality/value
The specificity of this model lies in its ability to directly calculate the amount of energy to be supplied without any iterative calculation. Furthermore, to be as close as possible to the technology used on LPBF machines, the kinematic behavior of the scanning head and the laser response time are also integrated into the calculation.

Abstract
Purpose
In the past decade, the use of neurophysiological measures as a complementary source of information has contributed to our understanding of human–computer interaction. However, less attention has been given to their capability in providing measures with high temporal resolution. Two studies are designed to address the challenge of measuring users’ cognitive load in an online shopping environment and investigate how it is related to task difficulty, task uncertainty and shopping convenience.
Design/methodology/approach
Two experiments using behavioral and neurophysiological measures are conducted to investigate how various types of the cognitive load construct can be measured and used in an online shopping context.
Findings
Results of the first study suggest that although all cognitive load measures are influenced by task difficulty, only accumulated load (i.e. total cognitive load experienced during a task) is sensitive to task uncertainty. Results of the second study show that convenience negatively influences accumulated load, and the latter negatively influences user satisfaction.
Practical implications
Our research offers practical value by providing designers with a validated method to measure users’ cognitive load, enabling the identification of usability issues and design improvement.
Originality/value
This study contributes to the literature by developing a rich and temporally high-resolution measurement of the cognitive load construct and examining how it can inform us about users’ cognitive state in an online shopping environment.

Abstract
Purpose
Assistive living technologies provide support for specific activities, transforming a home into a smart home. The purpose of this paper is to present how to design, implement, deploy and install a personalized ambient support system for the elderly suffering from Alzheimer’s disease (AD) and nighttime wandering.
Design/methodology/approach
The intervention presented in this paper proceeds in two phases. During the monitoring phase, the system determines the profile of the person with AD, based on nighttime routines. Data are gathered from sensors dispatched in the smart home, coupled with physiological data obtained from sensors worn by the person. Data are then classified to determine engine rules that will provide assistance to the resident to satisfy their needs. During the second phase, smart assistance is provided to the person via environmental cues by triggering rules based on the person’s habits and the activities occurring during night.
Findings
The paper develops the architecture of a non-intrusive system that integrates heterogeneous technologies to provide a calm environment during night and limit wandering periods.
Practical implications
The goal is to help people age well at home as long as possible and recover a regular circadian cycle while providing more comfort to the caregiver.
Originality/value
The system presented in this paper offers a calm and personalized environment with music and visual icons to soothe persons with AD and encourage them to go back to bed. It is installed at the patient’s home using wireless technologies.

Abstract
Purpose
This paper aims to propose an analytical thermal three-dimensional model that allows an efficient evaluation of the thermal effect of the laser-scanning path. During manufacturing by laser powder bed fusion (LPBF), the laser-scanning path influences the thermo-mechanical behavior of parts. Therefore, it is necessary to validate the path generation considering the thermal behavior induced by this process to improve the quality of parts.
Design/methodology/approach
The proposed model, based on the effect of successive thermal flashes along the scanning path, is calibrated and validated by comparison with thermal results obtained by FEM software and experimental measurements. A numerical investigation is performed to compare different scanning path strategies on the Ti6Al4V material with different stimulation parameters.
Findings
The simulation results confirm the effectiveness of the approach to simulate the thermal field to validate the scanning strategy. It suggests a change in the scale of simulation thanks to high-performance computing resources.
Originality/value
The flash-based approach is designed to ensure the quality of the simulated thermal field while minimizing the computational cost.

Abstract
Purpose
In a warehouse setting, where hourly workers performing manual tasks account for more than half of total warehouse expenditure, a lack of employee engagement has been directly linked to company performance. In this article, the authors present a laboratory experiment in which two gamification elements, goal setting and feedback, are implemented in a wearable warehouse management system (WMS) interface to examine their effect on user engagement and performance in an item picking task. Both implicit (neurophysiological) and explicit (self-reported) measures of engagement are used, allowing for a richer understanding of the user's perceived and physiological state.
Design/methodology/approach
This experiment uses a within-subject design. Two experimental factors, goals and feedback, are manipulated, leading to three conditions: no gamification condition, self-set goals and feedback and assigned goals and feedback. Twenty-one subjects participated (mean age = 24.2, SD = 2.2).
Findings
This article demonstrates that gamification can successfully increase employee engagement, at least in the short-term. The integration of self-set goals and feedback game elements has the greatest potential to generate long-term intrinsic motivation and meaningful engagement, leading to greater employee engagement and performance.
Originality/value
This article explores the underlying effects of gamification through two of the most prominent motivational theories (self-determination theory [SDT] and goal-setting theory) and one of the leading employee engagement models (job demands-resource model [JD-R[ model). This provides a theory-rich interpretation of the data, which allows to uncover the motivational pathways by which gamification affects engagement and performance.
