Abstract

Purpose

This paper aims to propose a new method for combining global path planning with local path planning, to provide an efficient solution for unmanned surface vehicle (USV) path planning despite the changeable environment. Path planning is the key issue of USV navigation. A lot of research works were done on the global and local path planning. However, little attention was given to combining global path planning with local path planning.

Design/methodology/approach

A search of shortcut Dijkstra algorithm was used to control the USV in the global path planning. When the USV encounters unknown obstacles, it switches to our modified artificial potential field (APF) algorithm for local path planning. The combinatorial method improves the approach of USV path planning in complex environment.

Findings

The method in this paper offers a solution to the issue of path planning in changeable or unchangeable environment, and was confirmed by simulations and experiments. The USV follows the global path based on the search of shortcut Dijkstra algorithm. Both USV achieves obstacle avoidances in the local region based on the modified APF algorithm after obstacle detection. Both the simulation and experimental results demonstrate that the combinatorial path planning method is more efficient in the complex environment.

Originality/value

This paper proposes a new path planning method for USV in changeable environment. The proposed method is capable of efficient navigation in changeable and unchangeable environment.

Abstract

Purpose

This study aims to examine the impact of corporate social responsibility (CSR) awards on firms’ market value considering these awards as a signal and proxy for the effectiveness of CSR practice.

Design/methodology/approach

There are 342 announcements of CSR awards in China from 2006 to 2017 screened and analyzed using the event study methodology.

Findings

The stock market reacts significantly negatively to CSR award announcements in the short term. Firms that are state-owned, belong to the manufacturing industry, outside east China, repeatedly win awards and are listed in the Chinese H-share market, experience a stronger stock market reaction. Interestingly, the long-term stock returns of award winners are significantly positive for multiyear holding periods.

Practical implications

The findings offer stakeholders clear guidelines on how to manage communications in the market to extract enhanced financial performance from CSR award announcements.

Originality/value

This study chooses CSR awards as a proxy for the effectiveness of excellent CSR practice. This study also contributes to the CSR literature by analyzing how investors use the award information to make investment decisions.

Abstract

Purpose

Despite its devastating nature, the COVID-19 pandemic has also catalyzed a substantial surge in the adoption and integration of technological tools within economies, exerting a profound influence on the dissemination of information among participants in stock markets. Consequently, this present study delves into the ramifications of post-pandemic dynamics on stock market behavior. It also examines the relationship between investors' sentiments, underlying behavioral drivers and their collective impact on global stock markets.

Design/methodology/approach

Drawing upon data spanning from 2012 to 2023 and encompassing major world indices classified by Morgan Stanley Capital International’s (MSCI) market and regional taxonomy, this study employs a threshold regression model. This model effectively distinguishes the thresholds within these influential factors. To evaluate the statistical significance of variances across these thresholds, a Wald coefficient analysis was applied.

Findings

The empirical results highlighted the substantive role that investors' sentiments and behavioral determinants play in shaping the predictability of returns on a global scale. However, their influence on developed economies and the continents of America appears comparatively lower compared with the Asia–Pacific markets. Similarly, the regions characterized by a more pronounced influence of behavioral factors seem to reduce their reliance on these factors in the post-pandemic landscape and vice versa. Interestingly, the post COVID-19 technological advancements also appear to exert a lesser impact on developed nations.

Originality/value

This study pioneers the investigation of these contextual dissimilarities, thereby charting new avenues for subsequent research studies. These insights shed valuable light on the contextualized nexus between technology, societal dynamics, behavioral biases and their collective impact on stock markets. Furthermore, the study's revelations offer a unique vantage point for addressing market inefficiencies by pinpointing the pivotal factors driving such behavioral patterns.

Abstract

Purpose

The sustainable development of the energy–economy–environment (3E) needs to ensure the balanced interplay between the energy–economy and the environment. Likewise, creating such balance has become a critical policy issue among countries worldwide. However, in the past, studies have ignored to create a balanced interplay of the energy–economy and environment. Therefore, to address said research gap, this paper aims to develop a graph model for conflict resolution (GMCR)-based strategy for the sustainable development of the 3E to ensure better environmental quality.

Design/methodology/approach

To develop a strategic framework for the balanced interplay between the energy–economy and the environment, the study used the GMCR approach and designed a mechanism for the sustainable development of the 3E to ensure better environmental quality in the context of Pakistan.

Findings

The results from the GMCR indicate that sustainable development of the 3E to ensure better environmental quality is possible when government focuses on the sustainable growth of the economy through environmental policies and the use of renewable energy.

Practical implications

By solving the 3E conflict, this study provides policy insights for the government of Pakistan for the sustainable development of the energy economy and the environment to ensure better environmental quality in the country.

Originality/value

For the first time, this paper tried to put forward a way through which conflicting objectives can be achieved together for the sustainable development of the 3E to ensure better environmental quality.

Abstract

Purpose

The purpose of this paper is to investigate the relation between various governance mechanisms and the transparency level by using a sample of the top 200 Chinese charity foundations on net assets.

Design/methodology/approach

Three types of governance forces are examined, including the board, the management and the capital providers. The Foundation Transparency Index (FTI), published by Chinese Foundation Center, is used as a proxy for the transparency level.

Findings

The evidences show that for the public foundations that can elicit fund from the public, providing compensation to the foundation managers could encourage them to increase the transparency level. Furthermore, the sophisticated donors also represent a useful governance force. For the non-public foundations that can only seek donors through private contacts, getting more members in their supervisory board and having more government grants are helpful in improving their transparency. The results are robust even after controlling for lagged FTI and other characteristics of foundations. And the transparency level is positively associated with the international connections for both types of foundations.

Research limitations/implications

This research is based on a limited sample. The results can hardly generalize to the other smaller foundations. However, the results are still meaningful for to the legislators, regulators and managers of Chinese charity foundations. Because the result implies that the overseas donors are effective monitors that could improve the foundation transparency, the newly published law may weaken this governance force.

Originality/value

This is the first paper that studies the governance of Chinese charity foundations. By using a third-party index to proxy for the transparency, the results complement existing literature.

Abstract

Purpose

Extant research has shown that workplace ostracism (WO) elicits counterproductive work behaviors, such as employee silence (ES), culminating in reduced job performance. However, lesser is known about the factors that buffer against this underlying linkage. With an emphasis on conservation of resource (COR) theory and social identity theory, this study investigates the hitherto unexplored moderating roles of moral identification (MI) and organizational identification (OI) in the relationship between WO and ES.

Design/methodology/approach

The study employed a time-lagged design to collect multi-source data from 250 employees working in the service sector organizations in Pakistan. Data are analyzed in SMARTPLS (v 3.3.3) to assess the measurement model and the structural model.

Findings

Results reveal that WO is positively correlated with ES and negatively correlated with job performance. At the same time, ES mediates the negative relationship between WO and job performance. In addition, MI and OI buffer against the positive connection between WO and ES. The positive association between WO and ES is less pronounced at high levels of MI and OI and vice versa.

Practical implications

The findings indicate that there is potential value in developing MI and OI, for which several interventions are discussed.

Originality/value

This study is one of the few efforts to outstretch the boundary conditions of ES. Moreover, this is the first study to investigate the role of identity-based perspective in the relationship between WO and ES.

Abstract

Purpose

There has been a growing concern about employee silence (ES) within an organization. ES is associated with low creativity and innovativeness, unethical organizational practices, avoidable errors and safety-related issues. The purpose of this study is to evaluate the mediating role of psychological insecurity (PI) in the relationship between leaders’ bullying behaviour (LBB) on defensive (DES) and acquiescent employee silence (AES).

Design/methodology/approach

Data were collected among police personnel working in Plateau state Nigeria. In all, a total of 350 responses were found useable for further analysis, of the 398 copies of the questionnaire administered. A structural equation modelling technique was used via SMART-PLS version 3.3.3 to test the hypothesized relationship.

Findings

The findings of this study revealed that leaders’ bullying positively and significantly influences both AES and DES, and PI was found to mediate the relationship between LBB and AES and DES.

Originality/value

LBB among the police has been under-researched, even when there is clear evidence of its existence. PI explains the mechanism through which LBB influences officers' silence.
