This study aims to achieve superior localization and mapping performance in point cloud degradation scenarios through the effective removal of dynamic obstacles. With the continuous development of various technologies for autonomous vehicles, the LIDAR-based Simultaneous localization and mapping (SLAM) system is becoming increasingly important. However, in SLAM systems, effectively addressing the challenges of point cloud degradation scenarios is essential for accurate localization and mapping, with dynamic obstacle removal being a key component.

This paper proposes a method that combines adaptive feature extraction and loop closure detection algorithms to address this challenge. In the SLAM system, the ground point cloud and non-ground point cloud are separated to reduce the impact of noise. And based on the cylindrical projection image of the point cloud, the intensity features are adaptively extracted, the degradation direction is determined by the degradation factor and the intensity features are matched with the map to correct the degraded pose. Moreover, through the difference in raster distribution of the point clouds before and after two frames in the loop process, the dynamic point clouds are identified and removed, and the map is updated.

Experimental results show that the method has good performance. The absolute displacement accuracy of the laser odometer is improved by 27.1%, the relative displacement accuracy is improved by 33.5% and the relative angle accuracy is improved by 23.8% after using the adaptive intensity feature extraction method. The position error is reduced by 30% after removing the dynamic target.

Compared with LiDAR odometry and mapping algorithm, the method has greater robustness and accuracy in mapping and localization.

This study aims to analyse what factors influence ethnic minority group (EMG) college students’ attitudes towards promoting online start-ups and how their different attitudes impact their final online start-up behaviours on the live streaming platform. Based on the COM-B behaviour changing model and the theory of liberal and conservative attitudes, the research model has been established in this study, and it divides influencing factors into the environmental opportunity unit and personal capability unit.

To test relationships among the environmental opportunity, personal capability and personal attitude units, the partial least squares path modelling and variance-based structural equation modelling have been applied on the SmartPLS. Meanwhile, this study considers the regional difference between China’s developed and less-developed regions and promotes multi-group analysis based on it.

Research results show that the online start-up opportunity and capability positively affect EMG college students’ liberal attitudes but reduce EMGs’ conservative attitudes. Meanwhile, this study finds four significant differences, such as the path between conservative attitude and EMG students’ online start-up behaviour and the path between online start-up capability and conservative attitude.

This paper analyses the relationship between influencing factors and EMG students’ online start-up attitudes based on the COM-B behaviour changing model, contributing to the theoretical implications. Meanwhile, considering the impact of regional differences, this paper promotes the multi-group analysis and compares EMG college students from developed regions and others from less-developed areas.

Online open innovation platforms provide opportunities for product users to participate in the innovation process and contribute their ideas to the platform. Nonetheless, they also present a significant challenge for platform managers, who select high-quality innovations from a massive collection of information with diverse quality.

In this study, the authors employed a machine learning method to automatically collect a real dataset of 2,276 innovations and 30,004 detailed comments from the online platform of IdeaExchange and then conducted empirical experiments to verify the study hypothesis.

Results show that extraversion, conscientiousness and openness to experience positively and directly influenced the quality of their innovation. Furthermore, an individual's social network position mediated among extraversion, neuroticism, conscientiousness and openness to experience and the quality of an innovation.

Results showed that extraversion, conscientiousness and openness to experience positively and directly influenced the quality of their innovation. Furthermore, an individual's social network position mediated among extraversion, neuroticism, conscientiousness, openness to experience and the quality of innovations.

This study combined the Big Five personality traits theory and social network theory to examine the association between user intrinsic personality traits, social network position and the quality of their innovative ideas in the context of online innovation platforms. Additionally, the findings provide new insights for platform managers on how to select high-quality innovation information by considering user personality traits and their social network position.

Identity, positioning and possibilities intersect differently for South Asian women in white academia. Within a broader migrant community that defines Australian life, these identities and positioning imply great possibility, but pursuing such pathways within academia is a walk on the last strand of resilience. This paper explores this tension of possibilities and constraints, using hope theory to highlight the cognitive resistance evident in the narratives of three South Asian women in Australian academia.

The authors use collaborative autoethnography to share their narratives of working in Australian universities at three different stages of careers, utilising Snyder's model of hope theory to interrogate their own goal-setting behaviours, pathways and agentic thinking.

The authors propose that hope as a cognitive state informs resistance and enables aspirations to contribute within academia in meaningful ways whilst navigating the terrain of inequitable structures.

The authors' use of hope theory as a lens on the intersectional experiences of career making, building and progression is a new contribution to scholarship on marginalised women in white academe and the ways in which the pathways of resistance are identified.

Little is known about gender relations in young African migrant families residing in Hong Kong (HK). This study aims to present a first-hand account of daily lived experiences of African international doctoral student couples residing in HK, with special emphases on their Africa–HK migratory motivations, perceptions of female-breadwinning status, the effects of HK Immigration policy on marital power structures and the influence of spousal relative statuses (“breadwinner” versus “dependent”) on couples gender role performances and decision-making participations.

This study used ethnographic method involving several indoor family visits, non-participant observations and 21 in-depth interviews in six African student families. Fieldnotes were taken and interviews were tape-recorded, transcribed and interpreted using thematic content analysis.

Couples, especially dependent men, had a hard time deciding to migrate to HK for family reunion, unlike dependent women who willingly resigned to join their husbands in HK. Among the male dependents, the main reasons for migrating included anticipated economic returns, while women migrated in response to neolocal cultural expectations. Overall, patriarchy persisted – while men had the final say over key household decision-making domains, women remained primary performers of household chores, but manifested little bargaining power, restraining husband’s ability to spend family income when they are the family’s sole-earners. Women’s relative breadwinning status had very minimal significant impact.

To the best of the author’s knowledge, this is the first study to examine the effects of HK’s immigration policy on married African students’ migration motivations and the effects of female-breadwinning status on spousal gender relations in HK’s African student migrant households.

Extant research suggests that consumers value the pursuit, attainment and retention of income security and financial well-being (FWB). The authors aim to expand the relevant literature by examining how consumers' psychosocial characteristics affect and are affected by the pursuit of those objectives.

The authors utilize partial least squares structural equation modeling (PLS-SEM) to evaluate the authors' hypotheses based on a sample of USA and Canadian consumers (n = 619).

The authors' PLS-SEM results provide support for the authors' hypotheses, indicating that individuals' insecure attachments – anxious and avoidant – relate negatively to their income security and FWB. The authors' results also show that these two desirable states relate positively to individuals' undesirable state of social loneliness.

The authors' methodology and findings illuminate the positioning of psychosocial factors as antecedents to and outcomes of income security and FWB. This research also provides a basis for understanding the linear vs curvilinear influences of income security on an individual’s social life.

In the present empirical study, the authors present a rare empirical examination of individuals' income security and FWB as outcomes of their psychosocial profile vis-à-vis insecure attachments. Drawing on established psychometric scales, this study expands the consumer psychology and FWB literature, showing significant linkages between insecure attachments, income security, FWB and social loneliness.

This study analyzes the advantages and disadvantages of the electoral mechanism of local education superintendents in South Korea, draws conclusions and makes suggestions for future reforms.

The research method of this study included document analysis and interviews. Document analysis was used to collect and analyze the relevant official documents of education superintendents across countries. Semi-structured interviews were conducted with four professors and two superintendents.

The results of the interviews indicate the following: 1) Korean stakeholders are getting more familiar with the direct election of superintendents, as the interviews indicate a more mature direct election system due to previous experience and public officials taking direct election into account; 2) The direct election of superintendents has advantages and disadvantages. The advantages include increasing the participation of the general public in education, and the disadvantages include conflict between the central government and local superintendents belonging to different political parties. However, the current system is likely to be retained; 3) The superintendent systems in various countries differ due to their respective traditions and social contexts. However, the authors can always learn lessons and implications from foreign countries if the authors compare their education systems with their foreign counterparts.

As far research limitations, although this was a small study, it shows the importance of collecting multiple stakeholders' views on the direct election of education superintendents as a basis for future reform of education management.

The Korean system for electing superintendents provides a good model for other countries reflecting on the educational autonomy and accountabilities of their own systems.

The direct election of superintendents provides an example of professionalism, independence and political neutrality in education that other countries can learn from. The separation of general and educational administration in Korea through direct elections protects educational activities from political influence.

In terms of originality/value, this study adds a new perspective to the debate about whether the general public should directly elect education superintendents, as well as to the literature on local education management.

This study aims to investigate how early and late adopters of Quality 4.0 (Q4.0) differ in terms of organizational performance.

The authors employed a grounded theory approach for interviewing 15 senior managers from diverse organizational contexts throughout the globe as part of their qualitative research methodology.

The research's findings were analyzed based on four types of performance: operational, financial, environmental and social. It was clear that early adopters of Q4.0 were sustaining superior performance in quality over time, even though their investment was significantly higher than that of late adopters. From a financial viewpoint, it was evident that early adopters had a competitive edge over their rivals compared to late adopters. Late adopters have utilized the notion of the circular economy (CE) more effectively than many early adopters in the context of environmental performance in order to establish a green economy and sustainable development.

Although the results of the interview indicate that Q4.0 is having some positive effects on social performance, in the authors' view, it is still least understood from an empirical standpoint.

The study's findings assist organizations in comprehending the performance differences between Q4.0 early adopters and late adopters.

The study aims to delve into the influence of tourism on the happiness of city residents, grounded in the overarching concept of livability. It posits that prioritizing residents’ happiness is crucial for effectively addressing cities’ challenges in balancing development and distinctiveness. The study pursues three primary objectives: first, establishing a potential correlation between city tourism and residents’ happiness; second, examining the contributing factors to this correlation and third, identifying potential mediators that influence the connection between tourism development and residents’ happiness.

Using a quantitative single-case design and partial least square analysis, the study underscores the intricate nature of various tourism development components. It specifically explores the roles of cognitive flexibility and social comparison in shaping the relationship between city tourism and happiness.

The findings make a distinctive contribution by revealing that not all tourism domains contribute positively to happiness. Furthermore, it sheds light on how tourism development impacts the emotional and cognitive dimensions of happiness, emphasizing the adverse effects of inequality and feelings of insecurity.

The study acknowledges certain constraints, including its employment of a cross-sectional design, the issue of generalizability, potential sampling bias and the reliance on subjective measurements when evaluating constructs like happiness and satisfaction with life. Using self-reported data introduces susceptibility to social desirability bias and individual perceptual differences, potentially resulting in measurement inaccuracies. Nevertheless, despite these limitations, the study’s findings offer valuable insights that contribute to both theoretical advancement and the realm of urban management.

The findings elucidated through the mediation analyses conducted for hypotheses three to seven shed light on the significant roles played by mental adaptation and social comparison mechanisms in shaping individuals’ happiness. These insights substantially enhance our understanding of this field. Particularly, the dimensions of social and environmental impact within tourism appear to counterbalance the positive effects stemming from the economic and cultural aspects. This suggests a scenario where an excessive focus on tourism development could potentially undermine the overall livability of the city. These outcomes further indicate the necessity for proactive interventions by destination managers. Their efforts should be directed toward enhancing the environmental and social domains, aiming to reinvigorate the sense of community among residents, which appears to be gradually waning.

The outcomes of this study emphasize the utmost significance of prioritizing residents’ happiness above mere considerations of economic growth when formulating efficacious strategies for tourism. By concentrating on the happiness of the local population, a harmonious resonance is established with Sustainable Development Goal 11, which advocates for the creation of habitable cities founded upon the principle that “a city that is not good for its citizens is not good for tourists.” This alignment underscores the interconnected nature of residents’ happiness and the sustainable development of tourism. Moreover, residents’ happiness plays a pivotal role in addressing the challenge that cities face in harmonizing growth and their uniqueness, ensuring competitiveness and sustainability.

The research underscores the need for a people-oriented perspective in urban planning and tourism development initiatives. The study identifies diverse factors impacting residents’ happiness in city tourism, highlighting the complex interplay of environmental, cultural and socioeconomic elements. It emphasizes income’s role but underscores nonmaterial factors and individual preferences. Overall, the study offers timely and valuable insights into the intricate connection between tourism development, residents’ happiness, living conditions and human perception, guiding urban planners and stakeholders.

This study aims to examine the effects of the historical prevalence of infectious diseases on contemporary gender equality. Previous studies reveal the persistence of the effects of historical diseases on innovation, through the channel of culture.

Drawing on the parasite stress theory, the authors propose a framework which argues that historical prevalence of infectious disease reduces contemporary gender equality. The study uses ordinary least squares and two-stage least squares in a cross-section with data from 122 countries between 2000 and 2021.

This study provide support for the underlying hypothesis. Past diseases reduce gender equality both directly and indirectly. The strongest indirect effects occur through innovation output. Gender equality analysis may take these findings into account and incorporate disease pathogens into the design of international social policy.

This study complements the extant literature by assessing the nexus between historical prevalence of infectious diseases and gender equality.
