Autonomous mobile robots (AMRs) play a crucial role in industrial and service fields. The paper aims to build a LiDAR-based simultaneous localization and mapping (SLAM) system used by AMRs to overcome challenges in dynamic and changing environments.

This research introduces SLAM-RAMU, a lifelong SLAM system that addresses these challenges by providing precise and consistent relocalization and autonomous map updating (RAMU). During the mapping process, local odometry is obtained using iterative error state Kalman filtering, while back-end loop detection and global pose graph optimization are used for accurate trajectory correction. In addition, a fast point cloud segmentation module is incorporated to robustly distinguish between floor, walls and roof in the environment. The segmented point clouds are then used to generate a 2.5D grid map, with particular emphasis on floor detection to filter the prior map and eliminate dynamic artifacts. In the positioning process, an initial pose alignment method is designed, which combines 2D branch-and-bound search with 3D iterative closest point registration. This method ensures high accuracy even in scenes with similar characteristics. Subsequently, scan-to-map registration is performed using the segmented point cloud on the prior map. The system also includes a map updating module that takes into account historical point cloud segmentation results. It selectively incorporates or excludes new point cloud data to ensure consistent reflection of the real environment in the map.

The performance of the SLAM-RAMU system was evaluated in real-world environments and compared against state-of-the-art (SOTA) methods. The results demonstrate that SLAM-RAMU achieves higher mapping quality and relocalization accuracy and exhibits robustness against dynamic obstacles and environmental changes.

Compared to other SOTA methods in simulation and real environments, SLAM-RAMU showed higher mapping quality, faster initial aligning speed and higher repeated localization accuracy.

As a cornerstone of team performance, learning depends on each member’s mindset. Drawing on implicit theories of intelligence, the purpose of this study is to investigate the relationships among individual members’ mindsets and shared leadership (SL) behaviors in design teams and the mediation role of team growth mindset (TGM) on that relationship.

The authors analyzed survey results based on individuals who participated in an international design competition. To test the hypothesized model, the data was analyzed by using SEM using Mplus 7.

The results indicated that an individual growth mindset (IGM; but not an individual-fixed mindset) has significant and positive direct effects on a team growth mindset and SL behaviors. In addition, a TGM mediates the relationship between an IGM and SL.

The research discusses several theoretical and practical implications for human resource development professionals and scholars to improve understanding of a TGM and its influence on individual mindsets and SL behaviors.

Introduction: In the modern period, environmental degradation has had negative effects on people’s health as well as the regular business environment. As a result, embracing a ‘Go Green’ philosophy has gained widespread acceptance among individuals and corporations worldwide. Going green is referred to as promoting eco-friendly ways and banks are essential in protecting the environment to improve our quality of life.

Purpose: This study will focus on the correlation between green banking practices (GBP), employee green behaviour (EGB), and banks’ sustainability performance and how this relationship will give a competitive edge in terms of sustainability to the banks adopting these GBP.

Methodology: EGB between GBP and bank sustainability occurrence is clarified by this study. The current study is descriptive and finds the relationship through previous literature reviews.

Findings: Employees are expected to be crucial in this transformation as the modern banking system adopts green banking initiatives and updates traditional banking processes. Employees help banks perform more sustainably by encouraging environmentally friendly banking practices.

Practical Implications: By understanding the mechanism, between GBP and bank sustainability, banks can adopt more effective strategies to enhance their sustainability performance while promoting environmentally friendly practices.

Increasing the need for education for sustainable development in universities requires an understanding of the predictors of students’ environmental concern (EC). In this paper, the authors focus on the EC of business students because of their future responsibility for business operations regarding the exploitation of natural resources. The aim of the study is to examine the predictors of business students’ environmental concern.

Based on the Norm Activation Model as the theoretical framework, this study hypothesizes the model of EC with two main predictors: ascription of responsibility for the environment (AOR), driven by locus of control and self-efficacy (LC/SE), and awareness of positive consequences of consumption reduction on the environment (AOC), driven by perceived environmental knowledge. Structural equation modelling was applied to confirm the conceptual model based on the responses of business students from six countries (Czech Republic, Croatia, Hungary, Poland, Slovakia and Spain) collected through an online survey.

The environmental concern of business students is predicted both by the ascription of responsibility and by awareness of consequences; however, the ascription of responsibility is a stronger predictor of EC. A strong impact was found for internal locus of control and self-efficacy on AOR, as well as a weaker influence of perceived environmental knowledge on AOC.

Sustainability education dedicated to business students should provide environmental knowledge and strengthen their internal locus of control and self-efficacy in an environmental context.

This study investigates the impact of network positions on inter-team conflicts and project success in megaprojects.

Network position is measured with centrality and structural holes. Substantive conflict and affective conflict reflect inter-team conflicts. A questionnaire survey was implemented in Chinese megaprojects, and 309 valid questionnaires were collected. The data were analyzed using structural equation modeling and bootstrapping methods.

The results show that centrality negatively impacts project success, while the presence of a team in a structural hole has no significant impact on project success. Centrality is negatively related to substantive conflict and is positively related to affective conflict. The team in a structural hole has a positive effect on substantive conflict and a negative effect on affective conflict. Substantive conflict and affective conflict have positive and negative effects on project success, respectively. The effect of network position on project success is mediated by inter-team conflict.

This research provides a reference for megaproject managers to better conduct network governance, manage inter-team conflict, and successfully manage projects. The study did not investigate the effects of changes in teams' network positions on project success. Future research should explore this facet of megaprojects.

This research adds to existing research on network position, and reveals that project network governance is important for megaproject success. This provides a new direction for megaproject management. Furthermore, the results validate constructive and non-constructive roles and the mediating role of inter-team conflict. This complements the literature on conflict management, providing a reference for megaproject managers when managing inter-team conflict.

Small and medium-sized enterprises (SMEs) are fundamental to the socioeconomic development of a country or region. They directly contribute to increasing employment generation and improving income distribution. Despite the importance of SMEs, there are still opportunities for developing works that support and guide SMEs to use digital technologies, especially to digitalize their customer service. Therefore, this work aims to propose drivers containing recommendations for developing and improving the digitalization of customer service in SMEs.

This work uses a qualitative approach to systematize the main SMEs' characteristics and identify the boosting elements of the digitalization of customer service in the scientific literature. To this end, the authors conducted a content analysis of the most influential empirical and theoretical articles on the theme published from 2016 to 2021 in the Scopus database.

This work identified 38 boosting elements of the digitalization of customer service based on the scientific literature. These elements were grouped into six drivers for developing and improving the digitalization of customer service. The drivers contain recommendations that were adapted for SMEs according to their characteristics and based on the experience of the authors of this work.

This work contributes to promoting socioeconomic development, providing important solutions for managers and owners of SMEs to improve their customer service. The proposed drivers support and encourage the use of digital technologies for developing and improving customer service, overcoming the challenges of digitalization in these companies. Thus, SMEs will be able to increase the satisfaction of their customers and improve their competitiveness.

The role of corporate social responsibility (CSR) fulfillment is critical when building resilience of project-based organizations (PBOs). However, fulfilling CSR to build a highly resilient PBO remains a black box problem. This study explores the different CSR combinations that enhance PBO resilience.

This study defines CSR in terms of shareholder, employee, and social CSR, and analyzes corporate characteristics in terms of corporate scale and nature. Data are collected from Hexun.com and the China Stock Market and Accounting Research Database (CSMAR). The qualitative comparative analysis (QCA) method is used to analyze 48 listed construction and engineering companies from China to explore the CSR configurations for PBOs in enhancing organizational resilience.

A large firm size is a necessary condition for high organizational resilience. We find six paths to build high and non-high resilience in PBOs, and the driving mechanisms of high and non-high resilience exhibit an asymmetric relationship.

This study cracks the black box of CSR fulfillment and PBO resilience. It reveals the CSR configurations that enhance or inhibit the resilience of PBOs. It also provides scientific basis for PBOs in their fulfillment of CSR in response to crises, and the enhancement of organizational resilience. Future research can be expanded to other industries, as the study sample is only limited to civil engineering construction companies. Since this study uses cross-sectional data, time series can be introduced in the future to further explore the relationship between CSR and organizational resilience.

This study provides targeted suggestions that can help decision-makers of construction companies to determine how they can fulfill CSR to enhance organizational resilience. At the same time, it can provide intellectual support for PBOs to cope with systemic crises and promote the fulfillment of CSR.

In terms of theoretical value, on the one hand, this study verifies the relationship between CSR fulfillment and PBO resilience, revealing its mechanism of action and multiple paths; on the other hand, it provides a new way of thinking for management research methods and enriches the theoretical study of organizational resilience.

The objective of this study is to examine the relationships among intellectual capital (IC), environmental compliance, corporate innovation and social media usage with respect to their influence on overall business performance.

A theoretical model and related hypotheses are offered, all of which are grounded in both the resource-based view and social network theory. The data were collected through a well-structured questionnaire, and 330 responses from manufacturing firms in Vietnam were deemed appropriate for data analysis using partial least squares structural equation modeling (PLS-SEM).

IC and social media usage have significantly positive effects on corporate innovation and business performance. Moreover, corporate innovation substantially enhances business performance. Furthermore, the results demonstrate that corporate innovation plays a partly mediating role in the research model. Meanwhile, IC fully mediates the relationship between environmental compliance and business performance.

This study offers valuable insights into intellectual capital, innovation, environmental compliance and social media usage for governments, practitioners and academics. Managers can incorporate social media usage strategies into their operational practices, enhancing environmental compliance, fostering innovation and ultimately promoting company success. Furthermore, the findings lead to practical recommendations for manufacturers seeking to adopt the CE model as part of taking a green production approach.

Organizational researchers have an ongoing interest in examining the connections among IC, innovation, environmental compliance and social media usage. Nevertheless, few papers have empirically investigated the interconnections among these constructs and their impact on organizational performance. This study examines these connections and provides concrete evidence for them.

The purpose of this study is to ascertain how cluster organisations have been fostering green transformation in Poland.

This paper adopts a multiple case study approach. Data collection methods involved in-depth interviews with cluster organisation managers and researchers to identify support measures for green transformation and to investigate the factors influencing their actions as well as a comprehensive analysis of documents, including cluster organisations‘ strategies.

Cluster organisations manage and participate in actions that create favourable conditions for pursuing low-carbon and circular economy ventures. They not only assist their members in overcoming obstacles related to green transformation but also engage non-members – which can lead to spillovers reaching beyond their borders. Their engagement takes place across all phases of the green transformation process.

For various reasons, the research was designed as qualitative to understand the opinions and experiences of various actors engaged in green transformation within cluster organisations’ ecosystems. The key factor influencing this decision stems from the fact that knowledge of the involvement of cluster organisations in supporting green transformation still needs to be completed and scattered. The limitations of the study include limited access to information and the fact that qualitative research allows for a certain amount of subjectivity, and the results should be generalised carefully. Moreover, the interviews were carried out with a non-random sample of participants. Another limitation of the study is related to biased views, which could have been shared by interviewees acting as representatives of the studied cluster organisations.

Cluster organisations have emerged as drivers of circular transition by promoting sustainable practices such as material recycling, biological recovery and parts harvesting. These initiatives contribute to reducing waste, conserving resources, and minimising the environmental footprint of industries. These organisations can be active agents of transformation, orchestrating collaborative efforts that have a far-reaching impact on industries and economies.

This is one of the first and most comprehensive studies on the role of cluster organisations in Poland in supporting green transformation. This paper identifies and systematises the actions undertaken to provide a clear understanding of the internal processes within cluster organisations.
