Abstract
Purpose
The purpose of this paper is to obtain a more accurate fatigue life of structures by introducing the surface roughness into fatigue life prediction model.
Design/methodology/approach
Based on the fatigue life prediction model with surface roughness correction, the shock absorber cylinder is taken as an example to verify the feasibility of the improved method. Based on the load of the shock absorber cylinder during driving, fatigue experiments are performed under longitudinal and lateral forces, respectively. Then, the fatigue life predicted by the modified model is compared with that predicted by the traditional model.
Findings
By comparing with the test results, considering the influence of mean stress, the Manson method is more accurate in life prediction. Then, the modified Manson-Coffin and Manson method with surface roughness is more accurate in life prediction under longitudinal force and lateral forces, respectively. This verifies the feasibility of the improved method with the surface roughness.
Originality/value
The research on the influence of surface roughness on fatigue life can lay the technical foundation for the life prediction of products and have great significance to the quality evaluation of products.

Abstract
Purpose
The COVID-19 pandemic had amplified feelings of isolation and alienation, particularly among school-aged children. The pandemic-related social distancing policies had led to a marked decline in students’ physical and social well-being, potentially fostering a sense of apathy among them. Upon returning to the “normal” in late 2022, a Chinese martial arts Outreach Program was launched in over 50 schools in Hong Kong, involving the entire student body and teachers at each school. This paper aims to explore the potential role of sports in enhancing student well-being in post-COVID times and as a societal response to the evolving sociopolitical landscape in Hong Kong, using the program as a case study.
Design/methodology/approach
Using ethnographic immersion, participant observation and semi-structured interviews, the study examines how the program sought to overcome the challenges students were facing during the pandemic through Chinese martial arts instruction and the teaching of traditional Chinese values.
Findings
The findings of this study reveal that the objectives of the Chinese martial arts Outreach Program not only centered on students’ immediate personal well-being but also entailed broader goals of advancing national education. The program’s design, which integrated sports and national education, emerged as a response to the pandemic and the sociopolitical transformations in Hong Kong, particularly following the implementation of the National Security Law.
Originality/value
The findings will deepen the understanding of how sport has been politicized as a means to respond to the societal changes in Hong Kong, especially after the pandemic.

Abstract
Purpose
This study explores how to develop high-tech industries in Hunan province and enhance regional competitiveness. Through the comprehensive quantitative analysis of the development status of the high-tech industry in Hunan province, this paper provides a reference for the development of the high-tech industry in China and the world.
Design/methodology/approach
This study constructs a comprehensive evaluation index system of regional competitiveness in Hunan province from the five dimensions of innovation, coordination, green, openness and sharing of the “new development concept.” Through the screening and analysis of relevant economic indicators in Hunan province from 2011 to 2020, the principal component analysis method is used to measure the five development dimensions, verify the hypotheses in the study and finally draw the conclusion.
Findings
Hunan's high-tech industry is positively correlated with Hunan's regional innovation development competitiveness, regional coordinated development competitiveness, regional green development competitiveness, regional open development competitiveness and regional shared development competitiveness. Among them, the promotion effect on innovation development is the best, followed by the promotion effect on green development, coordinated development and shared development dimension. In contrast, the promotion effect on the open development dimension is relatively weak.
Research limitations/implications
The statistical data selected in this study have certain timeliness. At the same time, the current economic environment is affected by the new corona pneumonia epidemic, showing specific particularity. In this context, it is bound to cause changes in the impact of high-tech industries on regional competitiveness. In addition, this paper studies the regional competitiveness of Hunan's high-tech industry from a macro perspective. Although relevant studies are conducted from five dimensions, there is a lack of micro-level research.
Social implications
From five aspects of the new development concept, this study provides suggestions for developing high-tech industries in Hunan province and even China and the path to enhance regional competitiveness.
Originality/value
Up to now, no article measures regional competitiveness with the five development dimensions of new development: innovation, coordination, green, openness and sharing, and quantitatively analyses regional competitiveness on this basis.

Abstract
Purpose
The objective of this study is to evaluate the overall technical efficiency, labor efficiency, capital efficiency and equipment efficiency of 30 Chinese construction sectors to foster sustainable economic growth in the construction industry.
Design/methodology/approach
This study employed the super-efficiency data envelopment analysis (SE-DEA) and artificial neural network model (ANN) to evaluate the industrial performance and improvement potential of the Chinese regional construction sectors from 2000 to 2017.
Findings
Results showed that the overall technical and capital efficiencies displayed relatively stable patterns. Equipment efficiency presented a relatively huge fluctuation during the sample period. Meanwhile, labor, capital and equipment efficiencies could potentially improve in the next five years. A spatial examination of efficiencies implied that the economic level was still a major factor in determining the efficiency performance of the regional construction industry. Beijing, Shanghai and Zhejiang were consistently the leading regions with the best performance in all efficiencies. Shandong and Hubei were critical regions with respect to their large reduction potential of labor, capital and equipment.
Research limitations/implications
The study focused on the regional efficiency performance of the construction industry; however, it failed to further deeply discover the mechanism that captured the regional inefficiency. In addition, sample datasets used to predict might induce the accuracy of prediction results. Qualitative policy implications failed to regress the efficiency performance of the industrial policy variables. These limitations will be discussed in our further researches.
Practical implications
Enhancing the overall performance of the Chinese construction industry should focus on regions located in the western areas. In comparison with labor and capital efficiencies, equipment efficiency should be given priority by eliminating outdated equipment and developing high technology in the construction industry. In addition, the setting of the national reduction responsibility system should be stratified to account for regional variations.
Originality/value
The findings of this study can provide a systematic understanding for the current and future industry performance of the Chinese construction industry, which would help decision makers to customize appropriate strategies to improve the overall industrial performance with the consideration of regional differences.

Abstract
Purpose
This study aims to evaluate in situ oxidative polymerization of aniline (Ani) as a post-processing method to promote extrusion-based 3D printed parts, made from insulating polymers, to components with functional properties, including electrical conductivity and chemical sensitivity.
Design/methodology/approach
Extrusion-based 3D printed parts of polyethylene terephthalate modified with glycol (PETG) and polypropylene (PP) were coated in an aqueous acid solution via in situ oxidative polymerization of Ani. First, the feedstocks were characterized. Densely printed samples were then used to assess the adhesion of polyaniline (PAni) and electrical conductivity on printed parts. The best feedstock candidate for PAni coating was selected for further analysis. Last, a Taguchi methodology was used to evaluate the influence of printing parameters on the coating of porous samples. Analysis of variance and Tukey post hoc test were used to identify the best levels for each parameter.
Findings
Colorimetry measurements showed significant color shifts in PP samples and no shifts in PETG samples upon pullout testing. The incorporation of PAni content and electrical conductivity were, respectively, 41% and 571% higher for PETG in comparison to PP. Upon coating, the surface energy of both materials decreased. Additionally, the dynamic mechanical analysis test showed minimal influence of PAni over the dynamic mechanical properties of PETG. The parametric study indicated that only layer thickness and infill pattern had a significant influence on PAni incorporation and electrical conductivity of coated porous samples.
Originality/value
Current literature reports difficulties in incorporating PAni without affecting dimensional precision and feedstock stability. In situ, oxidative polymerization of Ani could overcome these limitations. However, its use as a functional post-processing of extrusion-based printed parts is a novelty.

Abstract
Purpose
This work tries to shed light on what factors can influence, positively or negatively, the decision to license a patent from a university, in order to offer some recommendations that can contribute to increasing the number of patents licensed from universities.
Design/methodology/approach
Based on a sample of researchers at Spanish universities who have already registered patents, this work shows that the individual factors of the researcher outweigh the institutional factors in determining the decision to patent an invention. Likewise, the probability of patenting an invention is higher when the researcher's level of participation in the process is greater.
Findings
The results of our study allow us to affirm that, in the Spanish university setting, individual factors play a more important role in one's decision to license a patent than institutional factors. In this sense, the collaboration of companies or experts from outside of academia in the research from which the patent was granted is the most relevant factor.
Originality/value
This work, the first study of this type to be carried out in Europe, concludes with a recommendation for reinforcing the structure and functionality of technology transfer offices as a basic policy for the promotion and facilitation of commercial exploitation of innovation in the universities.
Propósito
Este trabajo intenta arrojar luz sobre qué factores pueden influir, positiva o negativamente, en la decisión de licenciar una patente de una universidad, con el fin de ofrecer algunas recomendaciones que puedan contribuir a aumentar el número de patentes universitarias.
Diseño de la investigación
Basado en una muestra de investigadores en universidades españolas que ya han registrado patentes, este trabajo muestra que los factores individuales superan a los factores institucionales a la hora de determinar la decisión de patentar una invención. Asimismo, la probabilidad de patentar una invención es mayor cuando el nivel de participación del investigador en el proceso es mayor.
Recomendaciones
Los resultados de nuestro estudio nos permiten afirmar que, en el ámbito universitario español, los factores individuales juegan un papel más importante en la decisión de solicitar una patente que los factores institucionales. En este sentido, la colaboración de empresas o expertos de fuera de la academia en la investigación a partir de la cual se otorgó la patente es el factor más relevante.
Originalidad
Este trabajo es el primer estudio de este tipo que se realiza en Europa y concluye con una recomendación para reforzar la estructura y la funcionalidad de las oficinas de transferencia de tecnología (OTRI) como política básica para la promoción de la explotación comercial de la innovación en las universidades.
