Abstract
Purpose
The deficiency of the mapping between fashion color (FoCo) value and linguistic color expression causes the difficulty of machine-based fashion understanding tasks that are heavily associated with color matching. The purpose of this paper is to propose the FoCo system and construct it with four steps, in order to bridge this gap.
Design/methodology/approach
The color distribution in HSB color space is analyzed to estimate the rough number of color categories. Similar color values are grouped to obtain the initial HSB value range for each color category. The intra-category color differences are calculated to determine their final HSB value ranges and Pantone color is used for fine-tuning.
Findings
With practical applications in mind, the FoCo system is designed as a hierarchical structure with three layers.
Originality/value
The FoCo system is designed as a hierarchical structure with three layers: color units for color matching-related tasks, color categories for style analysis tasks and color tones for color recognition tasks. Extensive experiments demonstrate the effectiveness of the FoCo system.

Abstract
Purpose
Efficient and high-accuracy intelligent color and material sorting systems are the main bottlenecks restricting the recycling of waste textiles. The mixing of waste textiles with different colors will make the reconstructed raw material of textile fiber useless or with low quality. In this study, some challenges about the automatic color sorting for waste textile recycling are discussed. A computer vision-based color sorting system for waste textile recycling is introduced, which can classify the required colors well and meet the efficiency requirements of an automatic recycling line.
Design/methodology/approach
There are four aspects, (1) two cameras with different exposure times and white-balance parameters are involved for establishing the computer vision system. (2) Two standard color databases with two cameras are constructed. (3) A statistical model to determine the colors of textile samples is presented in which uniform sampling of pixels and mid-tone enhancing techniques are exploited. (4) The experiments with a number of waste textile samples from a factory in Hong Kong are conducted to illustrate the efficiency of the developed system.
Findings
The experiments with a number of waste textile samples from a factory in Hong Kong are reported. The total classification accuracy performs good. The research methods and results reported in this study can provide an important reference for improving the intelligent level of color sorting for waste textile recycling.
Originality/value
It is the first time to introduce computer vision technology to a color sorting system for recycling waste textiles, especially in a real recycling factory in Hong Kong. The research methods and results reported in this study also deliver guidance for designing a computer vision-based color sorting system for other industrial scenarios.

Abstract
Purpose
Mainland Chinese students (hereafter called Mainland students) are a major source of international student applications. Some countries have initiated policies to enable Mainland students to stay and work after graduation. Additions to the literature, particularly more country-specific studies, are much needed to cast light on the employment issues for such Mainland students overseas. The purpose of this paper is to fill this gap by focussing on Mainland students who have completed teacher education programmes in Hong Kong and then served as teachers in Hong Kong schools (Mainland teachers). The incentives that attracted them to stay and work in Hong Kong and the challenges they faced were examined. Their future plans were also probed.
Design/methodology/approach
The study adopted a mixed methodology. Data collection comprised both a questionnaire survey and interviews. The semi-structured interviews provided opportunities for respondents to explain their answers, to narrate and widen the scope of data to areas hitherto unanticipated by the researchers.
Findings
Mainland teachers were attracted to stay on in Hong Kong to work for both intrinsic and extrinsic reasons. They were in fact settlers. They found the programmes they had taken to be practical and believed that they had acquired a niche situation in the teaching profession. Working and living in Hong Kong was satisfying, but some experienced social distance from local colleagues.
Originality/value
The paper can be read with reference to countries that recruit Mainland students and there is a possibility that some of them may stay behind to work. It sheds light on the selection criteria of such students, on ways to enrich their programmes, as well as their employment, living and social integration issues.

Abstract
Purpose
Since the launch of the Mainland and Hong Kong Closer Economic Partnership Arrangement (CEPA) in 2003, Hong Kong cinema is believed to have confronted drastic changes. Hong Kong cinema is described to be dying, lacking creative space and losing local distinctiveness. A decade later, the rise of Hong Kong – China coproduction cinema under CEPA has been normalized and changed the once pessimism in the industry. The purpose of this paper is to demonstrate how Hong Kong cinema adjusted its production and creation in the first 10 years of CEPA.
Design/methodology/approach
Beginning with a review of the overall development, three paradigmatic cases are examined for reflecting upon what the major industrial and commercial concerns on the Hong Kong – China coproduction model are, and how such a coproduction model is not developed as smooth as what the Hong Kong filmmakers expected.
Findings
Collectively, this paper singles out the difficulties in operation and the limit of transnationality that occur in the Chinese context for the development of Hong Kong cinema under the Hong Kong – China coproduction model.
Originality/value
This is the author’s research in his five-year study of Hong Kong cinema and it contributes a lot to the field of cinema studies with relevant industrial and policy concern.

Abstract
Purpose
The purpose of this paper is to examine the relationships between the civic mission of schools and students on participation in school governance through an empirical study. It articulates the importance of school mission on nurturing citizenship of high school students.
Design/methodology/approach
The research used a mixed method with questionnaire survey in the first phase and qualitative interviews in the second phase. Quantitative data were obtained from a survey completed by 3,209 students and 495 teachers (including principals) from 51 secondary schools in Hong Kong. Qualitative data were collected from 41 individual interviews with principals and teachers and 17 focus group interviews with 56 students in five case study schools.
Findings
Both students and teachers believed that good citizenship qualities should include students’ participation in school governance. Schools in general took up the civic mission to nurture good and participatory citizens. A mission of nurturing students to become good and participatory citizens made a significant and positive contribution toward achieving students’ actual participation in school governance. However, students’ actual impact on major school policies was minimal. A paradox existed whereby students, knowing their influence over managerial issues was much circumscribed, still gave it a higher rating than their teachers.
Originality/value
The paper contributes an empirical model for school leaders to develop school vision for promoting student participation in school governance. Based on a large-scale research supported by public funding, the paper contributes an empirical model for school leaders to develop school vision for promoting student participation in school governance. It further adds to the literature on relationship between citizenship education, civic mission of school and student participation in governance.

Abstract
Purpose
This paper reported an autoethnographic study based on the author’s reflections during and after COVID-19 in Hong Kong. The author took on the role of a teacher educator in supporting the professional development of both pre-service and in-service teachers facing the related challenges and difficulties during the pandemic. Through ongoing dialogues with different stakeholders, including PE teachers, school principals, and university academics as well as the author’s own reflective self, the study drew upon the author’s deliberate choice to situate the efforts to engage with critical pedagogy about the broader context of changes made by PE Teacher Education in higher education institution during the COVID-19 in Hong Kong.
Design/methodology/approach
This paper presents a generic self-reflective model with an autoethnographic approach for PE teachers who might seek resolutions and insight by referencing the author’s reflections about learning and teaching in and after the COVID-19 pandemic in Hong Kong.
Findings
The challenges and future development of PE were reflected.

Abstract
Aims to identify the job‐related barriers to creativity as perceived by managers and supervisors in the Hong Kong hotel industry. Two pilot tests using individual in‐depth interview and dichotomous selection test were conducted to identify possible barriers. Based on the result of the first pilot study, 25 job‐related barriers to creativity were consolidated and finally 17 statements were developed through the respondents’ selection in the second pilot study. Factor analysis of Principal Components Analysis with a Varimax Rotation was conducted and four major dimensions of barriers were identified with a factor loading of 0.5 or higher. Significant differences were observed when analyzing the demographic variable of education with the factor of “fear of change and criticism” and “time and work pressure”. Suggests recommendations on how to reduce the barriers inhibiting creativity in the hotel industry aiming at improving the creative potential of hotel employees.

Abstract
Purpose
The purpose of this paper is to explore the emergence of civil disobedience (CD) movements in Hong Kong in the context of the notion of civil society (CS).
Design/methodology/approach
The paper begins by rigorously defining the notion of CD, as well as the concept of CS and tracing its development in Hong Kong over the past several decades. By using a model of CS typology, which combines the variables of state control and a society’s quest for autonomy (SQA), the paper aims to outline the historical development of CD movements in Hong Kong. It also discusses the recent evolution of CS and its relationship with CD movements, particularly focusing on their development since Leung Chun-ying became the Chief Executive in 2012. Finally, by using five cases of CD witnessed in the past several decades, the relationship between the development of CS and the emergence of CD in Hong Kong has been outlined.
Findings
Four implications can be concluded: first, CD cannot emerge when the state and society are isolated. Second, the level of SC and the scale of CD are positively related. Third, as an historical trend, the development of SQA is generally in linear progress; SQA starts from a low level (e.g. interest-based and welfare-based aims) and moves upwards to campaign for higher goals of civil and political autonomy. If the lower level of SQA is not satisfied, it can lead to larger scale CD in future. Fourth, the CD movement would be largest in scale when the state-society relationship confrontational and when major cleavages can be found within CS itself.
Originality/value
This paper serves to enrich knowledge in the fields of politics and sociology.

Abstract
Purpose
Hong Kong’s musical scene is rapidly changing along with the evolving media landscape. The purpose of this paper is to examine the new way of Cantopop production and dissemination in the new media ecosystem. Furthermore, this study calls for a reconceptualization of the process of Cantopop listening and sharing as a form of public pedagogy within the online public space.
Design/methodology/approach
Based on the investigation into two of the leading local indie bands Kolor and Supper Moment, this study explores the implications that social media and participatory culture have for these indie bands. In this study, the music content and promotion strategy of the two bands, as well as the role of their online audiences are studied.
Findings
Social media leads to more democratic cultural production and distribution. The strong online audience engagement serves as the foundation for the popularity of the two Cantopop indie bands. In their music practice, the lyrics appear to be in alignment with the goals and interests of the listeners, which gives rise to greater participation by its audiences through social media. Under the context of interactive internet culture, listening and sharing Cantopop can be seen as an educational force, thus reinforcing the values and attitudes.
Originality/value
While many important works have examined various aspects of Cantopop, little attention has been paid to the indie bands. This paper attempts to reveal the recent development of local indie bands as a site under the interactive internet culture. It also gives insights to the significant role of Cantopop played in public pedagogy.
