Abstract

Purpose

Heavy fog results in low visibility, which increases the probability and severity of traffic crashes, and fog warning system is conducive to the reduction of crashes by conveying warning messages to drivers. This paper aims at exploring the effects of dynamic message sign (DMS) of fog warning system on driver performance.

Design/methodology/approach

First, a testing platform was established based on driving simulator and driver performance data under DMS were collected. The experiment route was consisted of three different zones (i.e. warning zone, transition zone and heavy fog zone), and mean speed, mean acceleration, mean jerk in the whole zone, ending speed in the warning zone and transition zone, maximum deceleration rate and mean speed reduction proportion in the transition zone and heavy fog zone were selected. Next, the one-way analysis of variance was applied to test the significant difference between the metrics. Besides, drivers’ subjective perception was also considered.

Findings

The results indicated that DMS is beneficial to reduce speed before drivers enter the heavy fog zone. Besides, when drivers enter a heavy fog zone, DMS can reduce the tension of drivers and make drivers operate more smoothly.

Originality/value

This paper provides a comprehensive approach for evaluating the effectiveness of the warning system in adverse conditions based on the driving simulation test platform. The method can be extended to the evaluation of vehicle-to-infrastructure technology in other special scenarios.

Abstract

Purpose

This paper aims to use active fine lane management methods to solve the problem of congestion in a weaving area and provide theoretical and technical support for traffic control under the environment of intelligent connected vehicles (ICVs) in the future.

Design/methodology/approach

By analyzing the traffic capacities and traffic behaviors of domestic and foreign weaving areas and combining them with field investigation, the paper proposes the active and fine lane management methods for ICVs to optimal driving behavior in a weaving area. The VISSIM simulation of traffic flow vehicle driving behavior in weaving areas of urban expressways was performed using research data. The influence of lane-changing in advance on the weaving area was evaluated and a conflict avoidance area was established in the weaving area. The active fine lane management methods applied to a weaving area were verified for different scenarios.

Findings

The results of the study indicate that ICVs complete their lane changes before they reach a weaving area, their time in the weaving area does not exceed the specified time and the delay of vehicles that pass through the weaving area decreases.

Originality/value

Based on the vehicle group behavior, this paper conducts a simulation study on the active traffic management control-oriented to ICVs. The research results can optimize the management of lanes, improve the traffic capacity of a weaving area and mitigate traffic congestion on expressways.

Abstract

Purpose

The purpose of this study is to effectively optimize vehicle lane-changing behavior and alleviate traffic congestion in ramp area through the study of vehicle lane-changing behaviors in upstream segment of ramp areas.

Design/methodology/approach

In the upstream segment of ramp areas under a connected vehicle environment, different strategies of vehicle group lane-changing behaviors are modeled to obtain the best group lane-changing strategy. The traffic capacity of roads can be improved by controlling group lane-changing behavior and continuously optimizing lane-changing strategy through connected vehicle technologies. This paper constructs vehicle group lane-changing strategies in upstream segment of ramp areas under a connected vehicle environment. The proposed strategies are simulated by VISSIM.

Findings

The results show that different lane-changing strategies are modeled through vehicle group in the upstream segment of ramp areas, which can greatly reduce the delay of ramp areas.

Originality/value

The simulation results verify the validity and rationality of the corresponding vehicle group lane-changing behavior model strategies, effectively standardize the driver's lane-changing behavior, and improve road safety and capacity.

Abstract

Purpose

This study mainly aims to examine whether entrepreneurs’ utilization of political connections is purely egoistic. Addressing this issue could shed light on traditional debate which concerns whether political connections still have strategic value at advanced stage of institutional transition today in China. Here, at the background of Chinese economic transformation, the utilization of political connections is studied, and a double-role model of the pro-self-mechanism and the pro-social mechanism between political connections and performance in China is put forward.

Design/methodology/approach

This study uses survey of questionnaires randomly from 363 entrepreneurs in Jiangsu, Anhui and Shandong Provinces of China and adopts the first stage and direct moderation model in examination.

Findings

The results show that there exists mediated mechanism of both pro-self and pro-social mechanism in the relationship between political connections and firm performance. The authors conclude that utilization of political connections is not only purely egoistic but also altruistic. So, both dark-side and bright-side mechanisms of political connections in China are of equal importance. In addition, the authors take into consideration of the contingency effects of institution, industry and firm-level factors of this moderation model. The pro-self and pro-social mechanisms have differences in terms of moderator-within and moderator-between comparisons of these three contingency effects. Among these comparisons, the pro-self-mediating mechanism is most sensitive to changes of institutional quality, whereas the pro-social mediating mechanism is most sensitive to the uncertainty of industry competition.

Research limitations/implications

This evidence furthermore verifies that the process of institutional transition is nonlinear and political connections still have strategic value in advanced stage of institutional transition today.

Originality/value

This study combines the dual perspectives of “give” and “take.” The former implies the pro-social motivation, while the latter implies the pro-self-motivation. Based on the framework of “resource-conduct-performance,” this study explores how these two mechanisms mediate the relationship between political ties and firm performance. In addition, the authors adopt the framework of “Strategy Tripod,” which was proposed by Peng et al. (2009) and examine the difference between pro-self and pro-social motivation at different level of institution environment improvement, industry dynamics and firm absorptive capacity.

Abstract

Purpose

The purpose of this study is to advance and test a new construct, harmony voice. Furthermore, according to the social influence theory, the relationship between zhongyong, an essential Confucian orientation mode and voice behavior, and the moderating role of coworker’s regulatory focus (promotion focus and prevention focus) has been examined.

Design/methodology/approach

A field study has been designed to test our hypotheses. We used samples of 291 employee–coworker dyads from a variety of organizations in China to test this study’s hypotheses.

Findings

The results of this empirical study show that zhongyong is positively related to harmony voice. Coworkers’ promotion focus strengthens the positive effect of zhongyong on harmony voice, and coworkers’ prevention focus weakens the positive effect of zhongyong on harmony voice.

Research limitations/implications

Traditionally defined voice and harmony voice might cause different risks to the voicer. However, how and what kinds of risks may be differently caused by these two types of voice behaviors have not been examined in this study. Future empirical research can explore the different effects of traditionally defined voice and harmony voice.

Practical implications

Managers responsible for managing Chinese employees should notice the difference in some important ways of thinking between Easterners and Westerners. Specifically, zhongyong may direct people to express issues related to work in ways that are different from those of their Western counterparts. Harmony voice can benefit the Chinese organization without disrupting organizational development.

Social implications

By examining the relationship between zhongyong and harmony voice, we contribute to identifying antecedents of voice by using an emic research perspective.

Originality/value

We made significant theoretical contributions to voice literature. We developed the construct of harmony voice, and we examined the relationship between zhongyong and voice.

Abstract

Purpose

This study aims to analyze the relationship between corporate social responsibility (CSR) and quality of accounting report, especially on earnings management (EM). In addition, potential moderators of this relationship are examined.

Design/methodology/approach

After a comprehensive study of potential mechanisms, the authors obtain plenty of empirical results to open the black box of the link between CSR and EM. Meta-analysis is applied on 51 studies from 35 papers. Further analysis is also carried out to determine the moderating effects, such as the cultural and sample selection differences in these papers.

Findings

CSR is negatively associated with EM. In addition, this effect is moderated by cultural difference, CSR measurement, and year of sample selection.

Research limitations/implications

Two patterns of the hypothesis between CSR and EM are confirmed based on agency cost theory, a theoretical shift of corporate ethics based on organizational moral perspective. Several useful suggestions are also provided for future studies on the empirical model and sample selection. Further research is necessary to clarify the agency cost behind the two theoretical patterns.

Practical implications

CSR is not a tool for firms to market but rather a strategy to ensure their consistency with moral principles, indicating that management should pay more attention to the potential damage of the incongruence between CSR and accounting reporting quality. CSR reporting quality remains an important issue for legislature to guarantee continued firm operations.

Originality/value

To the best of the authors’ knowledge, this study is the first to analyze the CSR and EM link using a meta-analysis and to consider its underlying mechanism under the global environment. Previous method design and sample selection are reviewed to provide reference for future studies.

Abstract

Purpose

The purpose of this paper is to empirically analyze whether and how managerial overconfidence affects stock price crash risk.

Design/methodology/approach

Based on a large sample of Chinese non-state-owned firms from 2000 to 2012, this study employs methods including multiple linear regression model, Heckman two-stage treatment effect procedure, firm fixed effects model and event study to clarify the causality relationship between managerial overconfidence and crash risk.

Findings

The authors find that firms with overconfident managers (chief executive officer or board chairs) are more likely to experience future stock price crashes than firms with non-overconfident managers. The effect of overconfidence on crash risk is more pronounced for firms with low transparency, suggesting that firm opacity facilitates overconfident managers’ bad news hoarding activities, which, in turn, increases stock price crash risk. The authors also show evidence that overconfident managers tend to disclose good news in a timely manner.

Originality/value

The authors add to the growing literature on stock price crash risk. Specifically, the authors find that the cognitive bias of board chair plays an important role in the bad news hoarding activities, thereby increasing the likelihood of stock price crash. This study also contributes to the literature that addresses the effects of managerial overconfidence on corporate finance issues.

Abstract

Purpose

The aim of the paper is to develop a method to block hydroxyl groups of epoxy acrylate (AAEP) in vinyl ester resin (VER) and to study the influence of modified VER on polyurethane/(VER) interpenetrating polymer network (PU/VER IPN).

Design/methodology/approach

The hydroxyl groups of AAEP in VER were blocked via different methods. Infra‐red spectroscopy was adopted to study the influence of the reagents, reaction temperature and feed molar ratio on the blocking effect of hydroxyl groups and the optimised technological parameters were determined. The PU/VER IPN and PU/modified VER IPN were prepared by simultaneous interpenetrating of VER (mixture of AAEP and butyl methacrylate with the mass ratio of 2/1) or modified VER and synthesised PU in their laboratory. The microstructure, dynamic mechanical properties and mechanical properties of PU/VER IPN and PU/modified VER IPN were compared.

Findings

The results showed that compared to unmodified IPN, because the hydroxyl groups in VER were blocked and no chemical cross‐linked structure existed between the two networks, the modified IPN showed dual‐continuous microsturcture with larger phase domain sizes between 20 and 50 nm. The effect damping temperature range of modified IPN was broadened and its damping performance was improved. The mechanical strength of modified IPNs decreased and their break elongation increased evidently.

Practical implications

The PU/modified VER IPN with excellent damping properties can be used in the applications where reduction of vibration and noise is desired.

Originality/value

The PU/modified VER IPN, in which no chemical cross‐linked structure existed between the two networks, was novel and its damping performance was improved and excellent.

Abstract

Purpose

This study aims to integrate Delone and McLean’s information system success (DMISS) model with the innovation resistance model to evaluate the relationship between behavioural intention to use (BIU) and innovation resistance in the context of neo-banking. The primary objective of this study is to identify the drivers of neo-banking adoption and the barriers to its adoption and incorporate constructs such as e-trust (ETR) and personal innovativeness (PIV) to provide a more comprehensive understanding of the factors influencing neo-banking adoption.

Design/methodology/approach

A structured survey-based questionnaire was used to gather data from a diverse sample population in India. The Partial Least Squares Structural Equation Modeling (PLS-SEM) model was employed to further examine the adoption of neobanking services and users' intention to use neobanking services.

Findings

This study reveals a significant correlation between BIU and the uptake of neobanking services, demonstrating the value of consumers' readiness to embrace these offerings. However, resistance to usage has emerged as a major obstacle for consumers concerned about data security, technology reluctance and perceived risks associated with digital-only neobanks.

Research limitations/implications

Analysing the driving and restraining factors will provide substantial information on the formation of consumers' decision-making processes in the Indian banking industry, which is undergoing rapid digital transformation. This information is of great importance to scholars, practitioners and policymakers, as it highlights the factors that may facilitate or impede the adoption of neobanking in India. The outcomes of this analysis will be of particular interest to researchers, experts and stakeholders in the field as they will provide valuable insights into the dynamics of consumer behaviour in the Indian banking sector.

Originality/value

This study represents an initial effort to examine BIUs and usage resistance within the rapidly developing neobanking sector in India. The findings of this study build on the existing research in this area and contribute to the ongoing discussion on the adoption of neo-banking.

Abstract

Purpose

The purpose of this paper is to investigate the effect of monetary loosening on corporate investment in an emerging market.

Design/methodology/approach

The paper begins this study by using a dynamic model to investigate the effect of monetary loosening on corporate investment. This paper uses money supply growth as a proxy for monetary loosening, as the State Bank of Vietnam relies mainly on a quantity-based policy. Next, this paper continues to analyze whether cash holdings are able to mitigate this effect. Finally, this paper examines the effect of monetary loosening on investment smoothing and the mitigating role of cash holding. The research sample includes 4,868 from 617 firms. This paper uses different regression techniques (i.e. pooled ordinary least squares clustered by firm, fixed effects, random effects and system generalized method of moments).

Findings

The research findings show that money supply growth is positively related to both corporate investment and investment smoothing. The effect of monetary loosening on corporate investment is mitigated by corporate cash holding. Moreover, this paper finds that the mitigating effect of cash holdings is stronger for financially constrained firms and non-state-owned enterprises.

Originality/value

Prior studies only focus on corporate investment under-tightening monetary policy; however, there is no research on firm investment under monetary loosening in an emerging market.
