Purpose
This paper aims to investigate the impact of environmental risk on corporate governance through market reaction to bank loan announcements.
Design/methodology/approach
Using the establishment of environment court in China as a quasi-natural experiment, this paper adopt the difference-in-differences approach based on listed firms during 2003–2013 to explore the impact of environment court on corporate governance.
Findings
This paper find that the environment court would weaken the cumulative abnormal return of loan announcements. Then, this paper confirm that the potential reason is that environment court worsens the interest conflict between majority and minority shareholders. Further, cross-sectional analysis suggests that bank’s supervision, market competition and analyst coverage can alleviate the impact of environment court on corporate governance.
Practical implications
Environment courts intensify firms’ internal interest disputes, thus causing the decrease of corporate governance, which can be observed through the effect of bank loan announcements.
Social implications
This paper provide reference for environmental policy formulation and implementation, firms’ decision-makings and improving the banking regulatory system.
Originality/value
This paper makes a contribution to the studies about the impact of environment court on firms’ decision-making and investors’ reaction, the impact of external factors on corporate governance and bank loan announcements effect.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Originality/value
Compared with LiDAR odometry and mapping algorithm, the method has greater robustness and accuracy in mapping and localization.

Abstract
Purpose
Intent detection (ID) and slot filling (SF) are two important tasks in natural language understanding. ID is to identify the main intent of a paragraph of text. The goal of SF is to extract the information that is important to the intent from the input sentence. However, most of the existing methods use sentence-level intention recognition, which has the risk of error propagation, and the relationship between intention recognition and SF is not explicitly modeled. Aiming at this problem, this paper proposes a collaborative model of ID and SF for intelligent spoken language understanding called ID-SF-Fusion.
Design/methodology/approach
ID-SF-Fusion uses Bidirectional Encoder Representation from Transformers (BERT) and Bidirectional Long Short-Term Memory (BiLSTM) to extract effective word embedding and context vectors containing the whole sentence information respectively. Fusion layer is used to provide intent–slot fusion information for SF task. In this way, the relationship between ID and SF task is fully explicitly modeled. This layer takes the result of ID and slot context vectors as input to obtain the fusion information which contains both ID result and slot information. Meanwhile, to further reduce error propagation, we use word-level ID for the ID-SF-Fusion model. Finally, two tasks of ID and SF are realized by joint optimization training.
Findings
We conducted experiments on two public datasets, Airline Travel Information Systems (ATIS) and Snips. The results show that the Intent ACC score and Slot F1 score of ID-SF-Fusion on ATIS and Snips are 98.0 per cent and 95.8 per cent, respectively, and the two indicators on Snips dataset are 98.6 per cent and 96.7 per cent, respectively. These models are superior to slot-gated, SF-ID NetWork, stack-Prop and other models. In addition, ablation experiments were performed to further analyze and discuss the proposed model.
Originality/value
This paper uses word-level intent recognition and introduces intent information into the SF process, which is a significant improvement on both data sets.

Abstract
The chapter examines the perspectives of campus advocates involved with the advancement of a comprehensive internationalization process at their state comprehensive university (SCU). Advocates explain their definitions of comprehensive internationalization, which are analyzed through an internationalization lens and framework of intercultural competence based on recent studies of Internationalization at Home (IaH). The study found faculty and staff perspectives of comprehensive internationalization to reflect attributes consistent with IaH, which is believed to be a vehicle for transmitting intercultural competence throughout the higher education institution. The context for this study is important as it takes place in an SCU located in a region where higher education is under significant public scrutiny.

Abstract
Purpose
The purpose of this paper is to propose a physically plausible solution based on hybrid bounding volume (BV) hierarchy for real‐time collision detection (CD) and response between a deformable and a rigid object.
Design/methodology/approach
Hybrid BV can be used to build BV hierarchy for the deformable object. The overlapping tests based on separating axis theorem (SAT) can be used to deal with CD. The physics conception of restitution coefficient and other important forces can be used to more real collision response.
Findings
Many methods focus on a specific application, but none of them gives an approach to physically plausible, real‐time simulation of CD and response up to 10,000 of deforming primitives. The paper finds that hybrid BV AABB‐Sphere for deformable object could increase the efficiency for CD, and restitution coefficient and other important physical concepts could provide more real collision response.
Research limitations/implications
The paper does not deal with all types of CD, such as CD for two deformable objects.
Originality/value
Using AABB‐Sphere hybrid BV to build hierarchical BV tree for deformable object, and OBB‐Sphere hybrid BV for rigid object. Owing to the variety of hybrid BV structures, during different phases of CD, different overlapping tests are used to accelerate CD effectively. Using important physics conceptions provides a good solution to simulate more real collision response.

Abstract
Purpose
This study seeks to examine mature consumers' motives in the selection of apparel and footwear brands and reasons for patronizing department stores. Differences in brand‐choice motives are assessed among age cohort groups within the mature consumers segment as well as mature consumer segments defined by various socio‐demographic and lifestyle factors (i.e. gerontographic segmentation).
Design/methodology/approach
A USA nation‐wide random sample of 10,400 head of households was surveyed in regards to reasons for choosing apparel and footwear brands and department stores.
Findings
The results show that older consumers not only differ from their younger counterparts but are also heterogeneous when it comes to reasons for choosing specific brands and department stores. Specifically, price reductions and special sales drive the majority of mature consumers' brand selection, while advice or requests of spouse or other relatives and recommendations of salespeople are important factors in brand selection. Ease of returning products or getting refunds and frequency of items on sale are the main drivers of department store patronization.
Practical implications
Marketing managers should consider preference differences in age and gerontographic segments when creating marketing strategies to serve mature consumers.
Originality/value
Typically, mature consumers are aggregated into a single age segment (e.g. over 55). This study examines mature consumer reasons for selecting apparel and footwear brands and department stores based not just on age, but also on individual characteristics, specifically, gerontographic characteristics. Suggestions for marketing strategies designed to appeal to gerontographic segments are provided.

Abstract
Purpose
Shape memory polymers (SMPs) respond with a change in their shape against a specific stimulus by memorizing their original shape and are reformed after deformation most often by changing the temperature of the surrounding without additional mechanical efforts. In the coming years, these polymers indeed will be in limelight to manufacture textile materials which will retain their shape even after prolonged use under disturbed conditions. This study aims at defining shape memory materials and polymers as well as their technological characteristics and also highlights application in various fields of textiles.
Design/methodology/approach
The methodology used to explain these SMPs have been carried out starting with the discussion on their properties, their physical nature, types, viz., shape memory alloys (SMAs), shape memory ceramics, shape memory hybrid, magnetic shape memory alloy, shape memory composites, shape memory gels and SMP along with properties of each type. Other related details of these polymers, such as their advantages, structure and mechanism, shape memory functionality, thermally responsive SMPs and applications, have been detailed.
Findings
It has been observed that the SMPs are very important in the fields of wet and melt-spun fibers to offer novel and functional properties, cotton and wool fabric finishing, to produce SMP films, foams and laminated textiles, water vapor permeable and breathable SMP films, etc.
Originality/value
The field of SMPs is new, and very limited information is available to enable their smooth production and handling.

Abstract
Purpose
This study aims to explore the role of urban streets as transitional edges in coordinating socio-spatial interactions within the urban environment. It will focus on how streets can revitalize their surrounding environments and shape sustainable urban living through their characteristics.
Design/methodology/approach
Employing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, this study systematically reviewed 67 international research articles published from 2013 to 2023. It delved into the functionalities of urban streets as transitional edges under various social and physical interactions, covering the multidimensional impacts of streets at the social, spatial and individual levels.
Findings
The results demonstrate that the physical and social dimensions of streets, through their characteristics as transitional edges, not only complement each other but also effectively promote social space interactions and sustainable urban development. As a key public space at the interface of social and physical realms, streets influence residents' daily lives and balance the socio-spatial environment.
Research limitations/implications
Although this study deepens the understanding of urban streets as transitional edges, it faces limitations due to the scarcity of literature related to transitional edges, which may affect the depth and breadth of the research. Future studies are required to further verify theoretical findings through field research and case studies and to explore practical applications of street design to enhance data comprehensiveness and availability.
Originality/value
The originality of this article lies in defining urban streets as dynamic transitional edge spaces, redefining their dual role in urban design to connect physical forms and social functions. Through a comprehensive literature review, this study provides theoretical support for urban planning and design practices, emphasizing their application value in promoting urban social interaction and sustainable development.
