Abstract
Purpose
The purpose of this paper is to examine the effect of mentoring on newcomer well-being, as mediated by newcomer socialization and moderated by proactive personality.
Design/methodology/approach
Data were collected at four time points in a sample of 227 newcomers. Regression analysis and bootstrapping method were used to test the hypotheses.
Findings
Mentoring had a positive and indirect effect on newcomer well-being through socialization. The moderated mediation analysis also revealed that proactive personality augmented the direct effect of mentoring on socialization and its indirect effect on well-being.
Research limitations/implications
Our data were collected in China, thereby limiting the generalization of the research findings. Future research can test our model in different cultural contexts.
Practical implications
Organizations should consider establishing a mentoring program to foster newcomer socialization and achieve well-being. Within the mentoring context, cultivating newcomers to become more proactive can predict higher socialization levels, resulting in higher well-being.
Originality/value
Previous research largely focused on the development of the well-being of tenured employees. Drawing on socialization resources theory, this study focuses on the newcomer well-being and proposes the influential mechanism and boundary condition of the relationship between mentoring and newcomer well-being. It sheds light on exploring the well-being development for newcomers.

Abstract
Purpose
Previous research on the factors influencing mentoring received has primarily focused on protégés' personalities and the similarity between protégés and mentors, whereas understanding on the role of protégés' skills is still limited. Drawing upon the social influence theory, this study investigated how newcomers' political skill influences newcomers' mentoring received and further affects newcomers' socialization outcomes (i.e. person-organization fit perception [P-O fit], performance proficiency and well-being).
Design/methodology/approach
Data were collected from 255 newcomers at a large Chinese information and technology (IT) company using a three-wave, time-lagged design.
Findings
The authors found that newcomers' political skill positively predicted mentoring received, which in turn positively affected newcomers' socialization outcomes.
Originality/value
These findings indicate that political skill enables newcomers to exert social influence on organizational insiders to achieve desirable socialization outcomes, enlarging both the mentoring and political skill literature.

This study aims to investigate the corrosion inhibitor effect of migrating corrosion inhibitor (MCI) on Q235 steel in high alkaline environment under cathodic polarization.
Abstract
Purpose
This study aims to investigate the corrosion inhibitor effect of migrating corrosion inhibitor (MCI) on Q235 steel in high alkaline environment under cathodic polarization.
Design/methodology/approach
This study investigated the electrochemical characteristics of Q235 steel with and without MCI by polarization curve and electrochemical impedance spectroscopy. Besides, the surface composition of Q235 steel under different environments was analyzed by X-ray photoelectron spectroscopy. In addition, the migration characteristic of MCI and the adsorption behavior of MCI under cathodic polarization were studied using Raman spectroscopy.
Findings
Diethanolamine (DEA) and N, N-dimethylethanolamine (DMEA) can inhibit the increase of Fe(II) in the oxide film of Q235 steel under cathodic polarization. The adsorption stability of DMEA film was higher under cathodic polarization potential, showing a higher corrosion inhibition ability. The corrosion inhibition mechanism of DEA and DMEA under cathodic polarization potential was proposed.
Originality/value
The MCI has a broad application prospect in the repair of damaged reinforced concrete due to its unique migratory characteristics. The interaction between MCIs, rebar and concrete with different compositions has been studied, but the passivation behavior of the steel interface in the presence of both the migrating electric field and corrosion inhibitors has been neglected. And it was investigated in this paper.

Abstract
Purpose
The purpose of this paper is to analyze the crowd stampede risk mechanism from the perspective of systems thinking.
Design/methodology/approach
Causal loop diagram is drawn to outline the non-linear interactions among complex factors across the whole system and dissect the contributory factors of crowd stampede accident. To systematically construct the theoretical framework and find fundamental solutions, co-word analysis with Citespace is used to get the critical data. An agent-based simulation using Pathfinder is conducted to develop a spatial model for the Shanghai Stampede Accident that happened in 2014.
Findings
The causal loop diagram is formed to not only illustrate the symptomatic solutions with a quick fix but also dissect the fundamental solutions through an underlying systemic analysis. The simulation shows that crowd stampede experiences an interactive process of accumulation, trigger, delay, break and diffusion of risk factors within the crowd system. A linkage effect among the multidimensional characters of individuals and the system accelerates the stampede risk deterioration. There exists delay of the result of effect from the deep-level measure.
Practical implications
A top-down approach is offered to policymakers for crowd stampede risk protocol design and synergic emergency control that may reduce the risk of the stampede.
Originality/value
In this study, SDFT paradigm is proposed as the critical solution for the crowd stampede accident. In addition, a chain effect of energy and a linkage effect within the crowd system is illustrated for in-depth understanding of crowd stampede risk.

Abstract
Purpose
The purpose of this paper is to introduce a new copper electroplating formula which is able to fill blind microvias (BVHs) and through holes (THs) at one process through a direct current (DC) plating method.
Design/methodology/approach
Test boards of printed circuit board (PCB) fragments with BVHs and THs for filling plating are designed. The filling plating is conducted in a DC plating device, and the filling processes and influence factors on filling effect of BVHs and THs are investigated. Dimple depths, surface copper thickness, thermal shock and thermal cycle test are applied to characterize filling effect and reliability. In addition, to overcome thickness, increase of copper on board surface during filling plating of BVHs and THs, a simple process called pattern plating, is put forwarded; a four-layered PCB with surface copper thickness less than 12 μm is successfully produced.
Findings
The filling plating with the new copper electroplating formula is potential to replace the conventional filling process of BVHs and THs of PCB and, most importantly, the problem of thickness increase of copper on board surface after filling process is overcome if a pattern plating process is applied.
Research limitations/implications
The dimple depth of BVHs and THs after filling plating is not small enough, though it meets the requirements, and the smallest diameter and largest depth of holes studied are 75 and 200 μm, respectively. Hence, the possibility for filling holes of much more small in diameter and large in depth with the plating formula should be further studied.
Originality/value
The paper introduces a new copper electroplating formula which achieves BVHs and THs filling at one process through a DC plating method. It overall reduces production processes and improved reliability of products resulting in production cost saving and production efficiency improvement.

Abstract
Purpose
In recent years, terrorist attacks have gradually become one of the important factors endangering social security. In this context, this research aims to propose methods and principles which can be utilized to make effective evacuation plans to reduce casualties in terrorist attacks.
Design/methodology/approach
By analyzing the statistical data of terrorist attack videos, this paper proposes an extended cellular automaton (CA) model and simulates the panic evacuation of the pedestrians in the terrorist attack.
Findings
The main findings are as follows. (1) The panic movement of pedestrians leads to the dispersal of the crowd and the increase in evacuation time. (2) Most deaths occur in the early stage of crowd evacuation while pedestrians gather without perceiving the risk. (3) There is a trade-off between escaping from the room and avoidance of attackers for pedestrians. Appropriate panic contagion enables pedestrians to respond more quickly to risks. (4) Casualties are mainly concentrated in complex terrains, e.g. walls, corners, obstacles, exits, etc. (5) The initial position of the attackers has a significant effect on the crowd evacuation. The evacuation efficiency should be reduced if the attacker starts the attack from the exit or corners.
Originality/value
In this research, the concept of “focus region” is proposed to depict the different reactions of pedestrians to danger and the effects of the attacker’s motion (especially the attack strategies of attackers) are classified. Additionally, the influences on pedestrians by direct and indirect panic sources are studied.

Abstract
Purpose
This study aims to explore the impact of green inclusive leadership (GIL) on green creativity (GCRY) within the context of higher education institutions (HEIs) in China. Specifically, it aims to examine the mediating roles of green intrinsic motivation (GIM), environmental knowledge (EK) and green thinking (GT) according to the componential theory of creativity (CTC).
Design/methodology/approach
The study employed a series of questionnaire surveys to collect data at three different time points from various sources. A total of 583 leader-faculty matched samples were obtained from two universities in China. The hypothesized relationships were tested using PROCESS macro in SPSS.
Findings
The findings indicate a beneficial influence of GIL on GCRY, mediated by GIM, EK and GT. Noteworthy interaction effects were observed, with GIM fostering EK and GT, and EK laying the groundwork for GT.
Practical implications
This research contributes to the existing literature by confirming the implementation of GIL and supporting the CTC, offering insights into the motivational processes driving GCRY and with practical implications discussed for the effective management of GIL and GCRY in higher education settings.
Originality/value
The novelty of this research model lies in its operationalization of environmental sustainability within the CTC. This study is the initial investigation highlighting the role of GIL in fostering GCRY within HEIs. The key contribution of the study is the investigation of GIM, EK and GT as potential mediators in the relationship between GIL and GCRY. This expands the theoretical boundaries of the CTC framework.

Abstract
Purpose
Motivating users to self-disclose online is significant to the long-term development of social media. Therefore, research on emotional disclosure, a significant form of self-disclosure, is required. By developing a stimulus-organism-response model, this study aims to investigate the mechanisms by which the social media environment affects users' online emotional disclosure.
Design/methodology/approach
This paper proposes two dimensions of social media environments, the online interpersonal environment (tie strength and network size) and the online information environment (self-reference). They are hypothesized to stimulate users' internal psychological needs (image management and emotional expression) which in turn will influence their emotional disclosure intentions. Using data from 489 users of WeChat Moments, the authors conduct partial least squares analysis to validate the research model.
Findings
The findings show that users' intrinsic psychological needs are stimulated by social media environments, but network size is not correlated with the need for emotional expression. The user's need for emotional expression promotes both positive and negative emotional disclosure intentions. The need for image management has a positive impact on positive emotion disclosure intentions but has a negative impact on negative emotion disclosure intentions.
Originality/value
This study contributes to the understanding of online emotional disclosure. It can also help social media managers create efficient plans to encourage users to create content.
