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.

The purpose of this paper is to analyze the crowd stampede risk mechanism from the perspective of systems thinking.

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

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.

Abstract

Purpose

The purpose of this paper is to identify the extent to which the company's post- initial public offering (IPO) outcome varies, along with the determinants of the post-IPO outcomes.

Design/methodology/approach

The authors use Cox proportional hazards models to examine what determines the company's post-IPO transition to one of the classified outcomes, delisting, acquisition due to strong performance, and acquisition due to weak performance. The authors develop models taking in a range of information concerning pre-IPO characteristics, offering characteristics, financial indicators, company specifics, industry features, and corporate ownership and governance.

Findings

Delisting is predominantly influenced by the company’ pre-IPO operating performance, as well as financial indicators and governance structure at the time of the IPO. Sound governance structure and good financial standing of the company aid it to achieve its goal. Mergers and acquisitions (M&As) of both forms are distinguished most significantly by ownership structure and industry features, which is consonant with the position that M&As are majorly motivated by social concerns and corporate control considerations. Centrally, corporate evolution is jointly shaped by market force and state control.

Practical implications

The findings can inform public policy decisions. There is a case for gradual introduction of institutional changes which facilitate, regulate, and monitor orderly market operations in line with the market mechanism and sound corporate governance.

Originality/value

The study is among the first efforts to examine what determines the company's transition to one of the post-IPO states following the IPO in China's stock market.

Abstract

Purpose

This research aims to figure out whether the pool testing method of SARS-CoV-2 for COVID-19 is effective and the optimal sample size is in one bunch. Additionally, since the infection rate was unknown at the beginning, this research aims to propose a multiple sampling approach that enables the pool testing method to be utilized successfully.

Design/methodology/approach

The authors verify that the pool testing method of SARS-CoV-2 for COVID-19 is effective under the situation of the shortage of nucleic acid detection kits based on probabilistic modeling. In this method, the testing is performed on several samples of the cases together as a bunch. If the test result of the bunch is negative, then it is shown that none of the cases in the bunch has been infected with the novel coronavirus. On the contrary, if the test result of the bunch is positive, then the samples are tested one by one to confirm which cases are infected.

Findings

If the infection rate is extremely low, while the same number of detection kits is used, the expected number of cases that can be tested by the pool testing method is far more than that by the one-by-one testing method. The pool testing method is effective only when the infection rate is less than 0.3078. The higher the infection rate, the smaller the optimal sample size in one bunch. If N samples are tested by the pool testing method, while the sample size in one bunch is G, the number of detection kits required is in the interval (N/G, N).

Originality/value

This research proves that the pool testing method is not only suitable for the situation of the shortage of detection kits but also the situation of the overall or sampling detection for a large population. More importantly, it calculates the optimal sample size in one bunch corresponding to different infection rates. Additionally, a multiple sampling approach is proposed. In this approach, the whole testing process is divided into several rounds in which the sample sizes in one bunch are different. The actual infection rate is estimated gradually precisely by sampling inspection in each round.
