Abstract
One of the most neglected sources of energy loss is streetlights that generate too much light in areas where it is not required. Energy waste has enormous economic and environmental effects. In addition, due to the conventional manual nature of operation, streetlights are frequently seen being turned ‘ON’ during the day and ‘OFF’ in the evening, which is regrettable even in the twenty-first century. These issues require automated streetlight control in order to be resolved. This study aims to develop a novel streetlight controlling method by combining a smart transport monitoring system powered by computer vision technology with a closed circuit television (CCTV) camera that allows the light-emitting diode (LED) streetlight to automatically light up with the appropriate brightness by detecting the presence of pedestrians or vehicles and dimming the streetlight in their absence using semantic image segmentation from the CCTV video streaming. Consequently, our model distinguishes daylight and nighttime, which made it feasible to automate the process of turning the streetlight ‘ON’ and ‘OFF’ to save energy consumption costs. According to the aforementioned approach, geo-location sensor data could be utilised to make more informed streetlight management decisions. To complete the tasks, we consider training the U-net model with ResNet-34 as its backbone. Validity of the models is guaranteed with the use of assessment matrices. The suggested concept is straightforward, economical, energy-efficient, long-lasting and more resilient than conventional alternatives.

Abstract
Purpose
The purpose of the paper is to analyse the characteristics, development and implementation of the Chinese labour arbitration system and its role in settling labour disputes.
Design/methodology/approach
The paper analyses official statistics and the arbitral cases published on the web sites of government labour and social security departments.
Findings
The paper finds that labour arbitration has become the most important mechanism for settling labour disputes in China since the middle 1990s. This trend indicates the fading of traditional political and administrative means due to the decreasing influence of governmental labour administration and the subordinate status of trade unions, and the emergence of the rule of law in setting labour terms. The effectiveness and fairness of labour arbitration is to a certain extent constrained by its limitations and workers' weak position in employment relations that prohibit it from fully upholding the Labour Law.
Research limitations
The paper shows that there is a paucity of literature devoted to labour arbitration in China. Further research is necessary to study labour arbitration, particularly the issues concerning: the frequency and reasons for workers to compromise in demands when claims, especially unfair dismissal cases; the process and the way in which arbitrators handle cases and make decisions; the fairness of arbitration awards; and the ways for improving competency and neutrality of arbitrators and arbitration committees.
Practical implications
The paper shows that the party‐appointed method is necessary to improve the two parties' control of arbitration process. The public should be allowed to access to case and arbitrator related information in order to increase the transparency of arbitration.
Originality/value
This is the first paper that introduces the labour arbitration system in China and analyzes its role in setting labour disputes and its potential for improvement.

Abstract
Purpose
The purpose of this study is to improve the performance of hollow fiber membrane and improve the separation efficiency.
Design/methodology/approach
By establishing a mathematical model of hollow fiber membrane gas separation, the influences of parameters such as pressure difference between the inside and outside of the filament, initial oxygen concentration of intake air, intake air flow rate and back pressure outside the filament on the polarization coefficient were analyzed, so as to explore the degree of influence of operating parameters on the concentration polarization, and put forward a technical scheme to reduce the concentration polarization.
Findings
Factors such as pressure difference between the inside and outside of the filament, initial oxygen concentration of intake air, intake air flow rate and back pressure outside the filament have a certain effect on the polarization coefficient. Among them, the polarization coefficient is positively correlated with pressure difference inside and outside the filament, initial oxygen concentration of intake air and back pressure outside the filament, and is negatively correlated with intake air flow.
Practical implications
Negative pressure suction on the permeation side can be used to increase the membrane permeation flow rate and reduce the concentration polarization.
Originality/value
The influence of concentration polarization on membrane performance is reduced by controlling various factors.

Abstract
This chapter reports on research that explores new and emerging extended reality [XR] technologies and how they might provide opportunities to trial, investigate, and put into practice their potential to reverse processes of atomisation, polarisation, and intercultural discomfort, in our contemporary society. This transdisciplinary practice-led research was underpinned by disciplines of computer science and engineering, social sciences, history, diverse community economics, human ecology, and Indigenous psychology. The collaboration between these various disciplines with the Māori and non-Māori community members allowed researchers to understand current societal stressors, prioritise relationality, and explore our shared values in the creation of XR experiences for exhibition in the galleries, libraries, archives, and museums [GLAM] sector.
A discursive design framework motivated, inspired, provoked, persuaded, and reminded inspiring collaborators, and visitors to the exhibitions, the value of (re)connecting with people and overcoming interracial awkwardness through these curated experiences. The XR technologies provided women a platform to discuss and reimagine first encounters between people from different cultural backgrounds. The technologies included a 180° stereoscopic projection, Common Sense, in which Māori Elder Irene Hancy shared her insight about social engagement and haptic HONGI in which visitors were greeted by a Māori woman Tania Remana via augmented reality. This research has been motivated by a desire to promote and support intercultural understanding in Aotearoa New Zealand, and it extends research by other non-Māori and Māori scholars.

Abstract
Purpose
The purpose of this paper is to provide an updated picture of the emergence of specific firms, cities and sectors of excellence in one of the best performing industrial areas of China: Guangdong Province.
Design/methodology/approach
The paper focuses on a single province‐case study and zooms on its leading territories, sectors, firms and policies. Geographical areas, industrial sectors and firms are defined “of excellence” according to their contribution to the overall industrial performance of the province.
Findings
High industrial performances are not equally spread in the province. They involve specific sectors (such as electronics), areas (Pearl River Delta) and even specific firms (particularly Chinese‐owned and SOEs). This picture is in line with the recent policy objectives (support to ODI by national companies, indigenous innovation, national and local champions, restructuring of SOEs) and with the history of preferential industrial development policies.
Research limitations/implications
Given the concentration of industrial excellence in the province, there is a need to further investigate the leading actors. Given the persistent policy practice to encourage excellences (areas, sectors and firms), there is a need to further investigate the linkages between provincial/local policies and performances. The empirical test on the existence of a causal link between policies and performances of specific territories and sectors is left for further research.
Originality/value
While much of the existing literature concentrates on the impressive industrial growth of China as a whole, the paper stresses the degree of concentration of such growth and the importance of focusing on specific leading actors in order to fully understand the industrial development of the country.
