The purpose of this study is to investigate the research on the influence of tech-innovation behavior on tech-innovation performance for Chinese manufacturing enterprises. Environmental performance has been taken into consideration with the green manufacturing and sustainability philosophy being a hotspot.

To verify the hypotheses and assumptions, a questionnaire was designed and a semi-structured interview was conducted for data collection. In addition, structural equation modeling (SEM) is applied to verify the influence model through assessing the fitting indexes based on the 317 questionnaire responses in the form of Likert-type scale.

Tech-innovation behavior and activity from direction, mode and investment behavior dimensions show their different positive influences on tech-innovation performance. This paper has creatively taken environmental tech-innovation performance into consideration, as well as economic performance. This investigation has provided the interpretation for each individual enterprise from three dimensions when conducting tech-innovation activity.

Tech-innovation behavior, which has been a subject of extended discussion during recent decades, is the effective activity or action for tech-innovation. However, there have not been any studies on the environmental performance influence study, as well as the economic performance from these three dimensions and framework.

As this paper discusses the tech-innovation performance influence study from three dimensions, individual enterprises can choose the corresponding action for the proper tech-innovation path, especially for small- and medium-sized enterprises.

This study helps managers recognize tech-innovation activities for better tech-innovation performance based on the empirical study.

The purpose of this paper is to find an efficient fabric defect detection algorithm by means of exploring the sparsity characteristics of main local binary pattern (MLBP) extracted from the original fabric texture.

In the proposed algorithm, original LBP features are extracted from the fabric texture to be detected, and MLBP are selected by occurrence probability. Second, a dictionary is established with MLBP atoms which can sparsely represent all the LBP. Then, the value of the gray-scale difference between gray level of neighborhood pixels and the central pixel, and the mean of the difference which has the same MLBP feature are calculated. And then, the defect-contained image is reconstructed as normal texture image. Finally, the residual is calculated between reconstructed and original images, and a simple threshold segmentation method can divide the residual image, and the defective region is detected.

The experiment result shows that the fabric texture can be more efficiently reconstructed, and the proposed method achieves better defect detection performance. Moreover, it offers empirical insights about how to exploit the sparsity of one certain feature, e.g. LBP.

Because of the selected research approach, the results may lack generalizability in chambray. Therefore, researchers are encouraged to test the proposed propositions further.

In this paper, a novel fabric defect detection method which extracts the sparsity of MLBP features is proposed.

To improve humanized management of Chinese teachers, the aim of this study is to, first, investigate the stress of Chinese teachers, and, second, to examine the relationship of teacher stress with coping strategies and social support. Moreover, an attempt is made to examine the moderating role of coping strategies in the relationship between social support and teacher stress.

Participants consisted of 363 teachers from 6 public primary and secondary schools (both regular and vocational schools), who completed 3 self-report questionnaires examining teacher stress, coping strategies and social support. The methodology used was t-test, correlation analysis and hierarchical multiple regression analysis.

There are more than 50 per cent of primary and secondary school teachers suffering from mild to extremely severe stress. Working environment (regular or vocational schools), gender and age affect teacher stress. Social support and passive strategies have significant relationships with teacher stress, and passive strategies moderate the relationship between social support and teacher stress.

The study is based on a sample taken from public primary and secondary schools, and the character of the research was cross-sectional. Therefore, we must be cautious in generalizing the findings. An important implication for management of the findings of this study is the importance of humanized management for teachers. To reduce teacher stress, more social support should be provided by educational administrators, and teachers should be trained to avoid using passive strategies.

Through the investigation into the teacher stress in both regular and vocational schools, this study provides a new point of view for human resource managers to control and reduce teacher stress in China by improved humanized management.

Fabric defect detection plays an important role in textile quality control. The purpose of this paper is to propose a fabric defect detection algorithm via context-based local texture saliency analysis.

In the proposed algorithm, a target image is first divided into blocks, then the Local Binary Pattern (LBP) technique is used to extract the texture features of blocks. Second, for a given image block, several other blocks are randomly chosen for calculating the LBP contrast between a given block and the randomly chosen blocks. Based on the obtained contrast information, a saliency map is produced. Finally, saliency map is segmented by using an optimal threshold, which is obtained by an iterative approach.

The experimental results show that the proposed algorithm, integrating local texture features and global image texture information, can detect texture defects effectively.

In this paper, a novel fabric defect detection algorithm via context-based local texture saliency analysis is proposed.

This empirical study of one of China's biggest take-out platforms during coronavirus disease 2019 (COVID-19) explores the legal rights and protections for gig workers' availability time.

The study uses a quantitative survey and interviews of take-out platform riders, investigating the intrinsic features of working time and availability time. Labour law professionals and scholars are interviewed to verify the findings.

The availability time of take-out platform riders is difficult to define under the current legal working-time framework. There is a need for a specific method to define availability time, considering the multiple factors in gig-take-out-sector work. One option is to apply working-time regulations to availability time but to use a proportionality test to preserve flexibility whilst the platform offers protection to the riders during that time.

Pandemic-related travel restrictions limited the authors' study to one take-out platform in Beijing. Future studies should cover a wider geographical area and multiple take-out platforms.

The study uniquely evaluates the availability time of take-out platform riders to determine appropriate public policy and theoretical implications. It proposes a proportionality test regulating riders' availability. In particular, the workers being “at leisure” during availability time could mitigate the platform's liability for full remuneration or moderate the ceiling of working hours. The occupational health and safety of riders must be fully protected, as they are still “at the platform's disposal” at that time.

Polyethylene terephthalate (PET) as a fiber molding polymer is widely used in aerospace, electrical and electronic, clothing and other fields. The purpose of this study is to improve the thermal insulation performance of polyethylene terephthalate (PET), the SiO₂ aerogel/PET composites slices and fibers were prepared, and the effects of the SiO₂ aerogel on the morphology, structure, crystallization property and thermal conductivity of the SiO₂ aerogel/PET composites slices and their fibers were systematically investigated.

The mass ratio of purified terephthalic acid and ethylene glycol was selected as 1:1.5, which was premixed with Sb₂O₃ and the corresponding mass of SiO₂ aerogel, and SiO₂ aerogel/PET composites were prepared by direct esterification and in-situ polymerization. The SiO₂ aerogel/PET composite fibers were prepared by melt-spinning method.

The results showed that the SiO₂ aerogel was uniformly dispersed in the PET matrix. The thermal insulation coefficient of PET was significantly reduced by the addition of SiO₂ aerogel, and the thermal conductivity of the 1.0 Wt.% SiO₂ aerogel/PET composites was reduced by 75.74 mW/(m · K) compared to the pure PET. The thermal conductivity of the 0.8 Wt.% SiO₂ aerogel/PET composite fiber was reduced by 46.06% compared to the pure PET fiber. The crystallinity and flame-retardant coefficient of the SiO₂ aerogel/PET composite fibers showed an increasing trend with the addition of SiO₂ aerogel.

The SiO₂ aerogel/PET composite slices and their fibers have good thermal insulation properties and exhibit good potential for application in the field of thermal insulation, such as warm clothes. In today’s society where the energy crisis is becoming increasingly serious, improving the thermal insulation performance of PET to reduce energy loss will be of great significance to alleviate the energy crisis.

In this study, SiO₂ aerogel/PET composite slices and their fibers were prepared by an in situ polymerization process, which solved the problem of difficult dispersion of nanoparticles in the matrix and the thermal conductivity of PET significantly reduced.

The purpose of this paper is to examine the actual legal effect of collective agreements by focusing on the litigation regarding the implementation of collective agreements in China where current literature on the topic is scarce.

This paper deploys both quantitative and qualitative methods to investigate the features of litigation regarding collective agreements. The judgments on collective agreement by people’s courts nationwide from 1 January 2014 to 31 December 2018 provide the primary empirical data. The intrinsic features of collective agreement disputes are investigated to delineate different sorts of theoretically presumed legal effect, namely contractual, normative and other (if any). A number of collective agreement templates and texts have been gathered and analysed to further explore the factors leading to collective agreement disputes. A dozen of labour law professionals, workers, scholars and trade union officials, were interviewed to verify the findings.

The number of collective agreement disputes is relatively small compared to the number of valid collective agreements or the volume of other labour disputes. This study found no litigation initiated by trade unions to claim a remedy against a violation of a collective agreement by an employer. However, a growing number of cases were filed by individual workers to complain about the terms and conditions of their individual employment agreements in contradiction to the existing collective agreement. These data do not mean that collective agreements lack problems or have no significance in action. A novel effect – a “substitution effect” – is evident in the existing labour litigations and relatively popular amongst employers, as they often refer to the collective agreement when a written individual agreement, as the mandatory document, is absent. The advent of substitution effect reflects a pragmatic view amongst Chinese labour law professionals, employers and workers.

Due to the recent establishment of the online judgments database, this study has focused on collective agreement litigation in people’s courts from 2014 to 2018, which is representative of the national trend of such disputes and thus provides valuable insights. Future studies should cover a wider time span and extend to the collective agreement disputes subject to labour arbitration to provide a fuller picture of the challenges and potential solutions.

By understanding the legal effect of collective agreements in reality, the legislature, workers and employers can act accordingly to enhance or empower it. The insignificant volume of both contractual and normative claims on collective agreements indicates the pressing need to inject something concrete into both substantive rights and the implementation mechanisms of collective agreements. The existence of substitution claims illustrates the room for further implementation of written individual agreements to reduce the need to borrow from collective agreements to fill the void left by the absence of individual agreements.

This study uniquely evaluates collective agreement disputes in China to seek their true legal effect, finding the substitution effect of collective agreements that was absent from the prior literature. The features of collective agreements are reflected in this work, together with public policy and theoretical implications.

The purpose of this paper is to apply the theory of cultural diplomacy to explore and explain the role and function of the Confucius Institution project and its implications for understanding of China's soft power projection.

This paper first presents the theories of soft power and cultural diplomacy as an analytic framework. It then delineates an interpretative illustration of the CI project as a platform for China's cultural diplomacy. The paper concludes with a discussion of the CI project's implications for understanding of China's soft power projection.

The paper argues that the Confucius Institute project can be understood as a form of cultural diplomacy that is state‐sponsored and university‐piloted, a joint effort to gain China a more sympathetic global reception. As such, the Confucius Institution project involves a complex of soft power techniques. However, it is not entirely representative of soft power capability, because the problems embedded in the project and in the wider society run counter to the Chinese government's efforts to increase the Confucius Institutions’ attractiveness and popularity.

This article sheds light on Chinese universities in the role of “unofficial cultural diplomats.” On this topic, further research may need to explore more fundamental issues that bear far‐reaching significance and impact, i.e. the mechanics of Chinese university involvement in Confucius Institutes. Interesting questions arising from this study may help open up a wider spectrum of research topics for understanding the university‐state relationship, cross‐border higher education, as well as the possibilities and limits of educational globalization. At this stage, this article serves as a start to move scholarship in that direction.
