Traditional visual simultaneous localization and mapping (SLAM) systems are primarily based on the assumption that the environment is static, which makes them struggle with the interference caused by dynamic objects in complex industrial production environments. This paper aims to improve the stability of visual SLAM in complex dynamic environments through semantic segmentation and its optimization.

This paper proposes a real-time visual SLAM system for complex dynamic environments based on YOLOv5s semantic segmentation, named YLS-SLAM. The system combines semantic segmentation results and the boundary semantic enhancement algorithm. By recognizing and completing the semantic masks of dynamic objects from coarse to fine, it effectively eliminates the interference of dynamic feature points on the pose estimation and enhances the retention and extraction of prominent features in the background, thereby achieving stable operation of the system in complex dynamic environments.

Experiments on the Technische Universität München and Bonn data sets show that, under monocular and Red, Green, Blue - Depth modes, the localization accuracy of YLS-SLAM is significantly better than existing advanced dynamic SLAM methods, effectively improving the robustness of visual SLAM. Additionally, the authors also conducted tests using a monocular camera in a real industrial production environment, successfully validating its effectiveness and application potential in complex dynamic environment.

This paper combines semantic segmentation algorithms with boundary semantic enhancement algorithms to effectively achieve precise removal of dynamic objects and their edges, while ensuring the system's real-time performance, offering significant application value.

This study aims to provide insights into Airbnb’s exit from the China market, specifically from the perspective of platform competition.

Based on the understanding of the evolution and competition of peer-to-peer (P2P) accommodation market in China and the double-edged network effects, this viewpoint article provides an in-depth discussion on Airbnb’s withdrawal from the China market.

This viewpoint paper contends that Airbnb faced increasing challenges in establishing unique competitive advantages against local rivals, who demonstrate a capacity for innovation and maintaining loyal customers in adapting to the market evolution. Consequently, this may inhibit Airbnb from attracting the mainstream market and lead Airbnb into a negative spiral, exacerbated by indirect network effects.

This study offers insights into the failure of an internationalisation process, drawing from an analysis of the competitive environment and the competition strategies of P2P accommodation platforms in China. These findings have practical implications for the implementation of international business strategies in P2P accommodation.

Green entrepreneurship (GE) is a novel concept in business and enhances environmentally friendly production and operation activities for “sustainable development” (SD). The aim of this study is to determine the drivers that contribute to the growth and success of “micro, small, and medium enterprises” (MSMEs) in the manufacturing sector in India. The study also examines the mutual and cause-and-effect relationships among these identified drivers.

The study used integrated research methodology and identified nine key drivers of GE (GEDs) through extensive literature reviews, theoretical perspectives (i.e. “resource-based view” (RBV), “natural resource-based view” (NRBV) and “critical success factor theory” (CSFT)), and expert opinions. Further, “total interpretive structural modeling” (TISM) and “matrice d'impacts croisés multiplication appliquée á un classment” (MICMAC) analysis are used here to develop a hierarchical model and cluster the drivers, and fuzzy “decision-making trial and evaluation laboratory” (fuzzy-DEMATEL) is used to develop causal relationships among the drivers. Further, a sensitivity analysis is conducted to ensure the robustness of the results.

Results indicated that green manufacturing and operation capability development, green business process management and attitudes toward developing sustainable business models significantly impacted GE and SD. The findings of this study help managers, policymakers, and practitioners gain an in-depth understanding of the drivers of GE.

The study considers a limited number of drivers and is specific to Indian manufacturing MSMEs only. Further, a limited number of experts from different enterprises are considered for data analysis. This study is also based on interrelationships and their relative importance based on multicriteria decision-making techniques. This study aids government decision-making, policy formulation and strategic decision-making for manufacturing businesses in achieving SD goals. In addition, this research also encourages green entrepreneurs to start eco-driven companies and facilitate the use of environmentally friendly goods to offset environmental challenges and accomplish sustainable development goals.

This study proposes an integrated methodology that will benefit managers, practitioners and others in developing strategies and innovations to improve and develop green practices. This study further helps with responsive, sustainable business development in various manufacturing MSMEs.

As the lines between physical and virtual worlds blur, this chapter delves into the transformative potential of the smart technology of Metaverse for people's mobility. Through a literature review, the concepts of smart city and Metaverse are revealed, and a comparison between urban mobility and virtual mobility is conducted, looking for a seamless blend of virtual and physical realms. This chapter paves the way for exciting possibilities, from enhanced travel experiences to environmental and societal benefits. However, cautiously, acknowledging the potential downsides of relying on the virtual realm in mobility, this chapter advocates for a balanced approach. Ultimately, this chapter seeks to ignite a conversation about reimagining our cities with Metaverse-driven mobility as a guiding force, where people and places harmoniously converge with Metaverse technology. By combining real-time information, virtual platforms, shared mobility services, efficient urban design and supportive policies, people can make smarter mobility choices that reduce environmental impact and enhance the overall travel experience.

The quality of service determines whether service firms can satisfy customers and achieve business quality and sustainability. As contemporary service firms are dependent on both team and employee to serve customers, it is important to investigate how to simultaneously facilitate team service performance (TSP) and employee service performance (ESP). Our aim is to build a multilevel model of the curvilinear effect of task conflict (TC) on TSP and ESP, as well as the moderating effects underlying the above curvilinear relationships.

Two-sourced data were obtained from 47 team leaders and 326 employees in Chinese hotels. Multilevel structural equation modeling was utilized for validating the model.

The results revealed that TC exerted a curvilinear effect on both TSP and ESP. Ethical climate (EC) and internal knowledge transfer (IKT) served as moderators strengthening the curvilinear nexus between TC and ESP.

We contribute to the conflict-performance stream in management literature by unmasking the curvilinear effects of TC on both TSP and ESP, and the moderation mechanisms underlying such curvilinear effects.

This study explores the role of industrial co-agglomeration and digital economy in influencing the green high-quality development of the Yellow River National Cultural Park to provide countermeasures and suggestions for promoting the whole-area high-quality development.

This study is based on panel data from 56 cities from 2010 to 2022. First, a Super-SBM model is built to evaluate green high-quality development. Secondly, location entropy is used to measure industrial co-agglomeration and the entropy weight method is used to measure the digital economy. Finally, the panel Tobit model is used to analyze the impact of industrial co-agglomeration and digital economy on the green high-quality development of Yellow River National Cultural Park.

This study found that (1) industrial co-agglomeration has a negative implication in green high-quality development, while the digital economy boosts green high-quality development; (2) industrial co-agglomeration is a less critical dependency on the level of development of the digital economy in influencing green high-quality development, while the facilitating effect of the digital economy is more dependent on industrial co-agglomeration and (3) the trend of slow growth in industrial co-agglomeration and digital economy development, with significant regional differences in green high-quality development.

Undeniably, our study has several limitations. Firstly, as the study area only includes some cities in individual provinces, such as Qinghai, this paper only analyzes at the city level, which does not better reflect the differences between provinces; secondly, this study only adopts one method to determine the digital economy. In the future, other methods can be explored to measure digital economy; finally, in addition to the main role of digital economy and industrial co-agglomeration, other factors may also affect the green high-quality development of YRNCP. Future research should introduce other variables to improve the theoretical framework.

First, it provides countermeasures and suggestions for promoting the green high-quality development of YRNCP. Second, it helps to implement the new development concept, cultivate the new quality productivity of culture and the tourism industry and promote the green high-quality development of YRNCP. Third, it provides references to improve the management measures and related policies of the YRNCP more accurately and efficiently. Fourth, it helps to build a new development pattern and has important practical significance in promoting the high-quality development of the whole basin, protecting and inheriting the Yellow River Culture and helping the Chinese-style modernization and development, which are of great practical significance.

The research is carried out from the new perspective of industrial co-agglomeration and digital economy, which provides the theoretical basis and reference for solving the problem of green high-quality development of YRNCP. Second, it broadens the research idea of green high-quality development. Third, it quantitatively analyzes the impact of industrial co-agglomeration and digital economy on the high-quality development of YRNCP, deepening the research on the green high-quality development of YRNCP. Fourth, it helps to enrich and improve the theoretical research related to the national cultural park development and has positive significance in promoting the management and innovation of the cultural industry and the construction of related disciplines.

The paper’s findings illustrate the functional relationship of the digital economy and industrial co-agglomeration with green high-quality development and propose countermeasures to facilitate the high-quality development of the Yellow River National Cultural Park.

Transport and logistics companies (TLCs) have adopted green practices to reduce their emission and waste in support of environmental protection requirements. However, not all green practices of TLCs have resulted in green performance (GP) because of inherent variations in internal abilities and external factors affecting firms in different operational environments. Using institutional (INT) and resource-based view (RBV) theories we develop a model that shows how institutional pressures and internal abilities impact TLCs’ GP.

Underpinned by INT and RBV theories, this study utilised structural equation modelling on a cross-sectional survey of 222 TLC firms operating in the Philippines.

The study reveals that TLCs’ regulatory compliance, social obligations and competitor pressures have significant direct effects on TLCs’ GP while supplier integration and resource capabilities serially mediate the relationships. The findings indicate that institutional pressures and internal abilities that shape firms’ environmental policies and procedures explain TLCs’ GP.

As a result of the cross-sectional nature of our data, findings may be time, population and prevailing situation dependent. The long-term validity of the research can be improved if longitudinal design is employed. We collected data from a single respondent considered as the best respondent. However, with time and resource availability, a jury of executives for each company would have been a better alternative respondent.

The findings of this research provide TLC managers, policymakers and other stakeholders with much-needed guidance for crafting policies and strategies for handling the challenges of caring for the planet and maintaining sustainable operations.

Improving green practices of TLCs to enable waste and emission reductions is critical to the health and well-being of people and the planet. An environment free of pollution will result in fewer health challenges, fewer medical/insurance-related expenses, and, above all, enable a higher quality of life and a more productive workforce.

Studies have extensively explored the green practices of TLCs as well as the influences of both institutional pressures and internal abilities of TLCs on their green practices. This study identifies critical factors that significantly affect the GP of TLCs and provides a conceptual framework for a better understanding of the dynamics of strategic, tactical and operational issues that TCLs may face in their effort at greening the sector.

This paper aims to study how the timing of these decisions affects the total profit and the individual profits of the two agents.

This paper study a supply chain for a network good where there is a manufacturer and a retailer. The manufacturer determines its wholesale price and its share in the retailer’s advertising cost while the retailer decides the retail price and the advertising cost.

This paper finds that a stronger network externality leads to higher prices and higher advertising efforts. This increases the profits of both manufacturer and retailer, but the manufacturer’s share of advertising costs depends on the order in which the supply chain enterprise make their decisions, the strength of network externality and the effect of advertising determines which decision timeline results in a higher price and greater advertising effort. The manufacturer prefers the price decision to be made before the advertising decision, while the retailer prefers these decisions to be made simultaneously.

Although this paper studies the price and advertising decision-making order preferences of channel members based on network externalities, this research can also be expanded from the following aspects based on network effects. First, network externality affects advertising cooperation between both parties in the situation such that the pricing power of retail prices is transferred from the retailer to the manufacturer and the retailer relies on revenue sharing (revenue sharing contract, nonwholesale price contract. Second, the manufacturer dominates the issues in the supply chain, but in reality, a retailer can also be the dominator or there are no dominators (Nash equilibrium). Finally, it is possible to consider pricing and advertising decisions in situations where two manufacturers or retailers compete.

When the price is reasonable, advertising investment is the main determinant of product sales. The greater the intensity of network externalities the more retailers will be willing to invest in advertising. An increase in the intensity of network externalities may not necessarily enhance manufacturers’ motivation or cooperative advertising, but it depends on the decision-making sequence. The strength of network externalities determines the decision-making sequence preferences of supply chain channel members whose preferences vary leading to conflicts of interest.

The impact of cooperative advertising or decision sequence on corporate decision-making has not been considered. To fill this gap, the paper integrates network externality and supply chain cooperative advertising models, focusing on the impact of network externality on pricing and advertising decisions, as well as on the sequence of decisions.

Appealing to the resource-based view and the resource advantage theory, this research aims to ascertain the complementarity of entrepreneurial and market orientation in enhancing the performance of small and medium enterprises.

Following a survey design, a self-administered questionnaire containing scales adapted from leading previous studies was used to collect data from 400 executives working in small and medium enterprises in Pakistan. Partial least squares-based structural equation modeling was performed to analyze the measurement and the structural models and test the significance of the hypothesized relationships.

It has been found that market orientation and entrepreneurial orientation enhance firm performance directly and indirectly with marketing capabilities and competitive strategies (partially or fully) mediating these causes and effects relationships.

The study adds to the literature on entrepreneurship, marketing and strategy and has significant ramifications for managers and public policymakers desiring to boost the performance of small and medium enterprises, which is crucial to the economic growth of developing nations, through nurturing and leveraging intangible resources such as market orientation, entrepreneurial orientation and marketing capabilities.

It is one of the rare attempts to investigate the complementarity of entrepreneurial orientation and market orientation, channeled through marketing capabilities and competitive strategies to boost SME performance, that too in the context of a developing country.

Brand gestalt has emerged as a crucial concept in marketing and branding, denoting the holistic perception and overall impression that consumers develop about a brand. This concept gains significance as it serves to measure the overall identity of a brand. Despite its importance, both empirical and theoretical exploration of this concept remains limited, particularly in the context of place branding. The present study aims to bridge the theoretical gap surrounding the interplay between brand gestalt, tourist attitude and loyalty within the city branding domain. In particular, it aims to comprehensively explore the dimensional impact of city brand gestalt (CBG) on tourist attitude, satisfaction and loyalty.

The primary data were collected through a self-administered online questionnaire containing 35 items, developed and adapted from the literature review. A total of 314 samples of Bitung City visitors were recruited, resulting in a 79% response rate. Structural equation modeling was performed using SmartPLS 3 to validate the research hypotheses.

The findings of the study indicate that CBG has a substantial and positive influence on tourist attitudes, satisfaction and loyalty. Furthermore, it was discovered that tourist attitude and satisfaction play a partial mediating role in the relationship between CBG and tourist loyalty.

This study is a seminal contribution to understanding the link between CBG, tourist attitude, satisfaction and loyalty. It offers valuable insights for city destination management in designing strategies and interventions to foster positive tourist attitudes, increase satisfaction and sustain loyalty. In particular, it emphasizes the necessity of ongoing investments in maintaining a positive holistic brand experience (i.e., brand gestalt) that aligns with evolving expectations. The study highlights the need to develop a compelling narrative and consistent messaging tailored to the target audience's values and aspirations. Additionally, it underscores the importance of providing exceptional sensory experiences that appeal to the target audience.

To the best of the authors' knowledge, this study is among the first to examine the role of brand gestalt in the context of city branding. Understanding the holistic interaction of the four brand gestalt elements – story, sensescape, servicescape and stakeholders – is crucial for fostering tourists' positive attitudes, satisfaction and loyalty toward urban destinations. The proposed CBG model offers a conceptual framework to guide future research in city branding.
