This paper presents a new indirect scaffold fabrication method for soft tissue based on rapid prototyping (RP) technique and preliminary characterization for collagen scaffolds.

This paper introduces the processing steps for indirect scaffold fabrication based on the inkjet printing technology. The scaffold morphology was characterized by scanning electron microscopy. The designs of the scaffolds are presented and discussed.

Theoretical studies on the inkjet printing process are presented. Previous research showed that the availability of biomaterial that can be processed on a commercial RP system is very limited. This is due mainly to the unfavorable machine processing parameters such as high working temperature and restrictions on the form of raw material input. The process described in this paper overcomes these problems while retaining the strength of RP techniques. Technical challenges of the process are presented as well.

Harnessing the ability of RP techniques to control the internal morphology of the scaffold, it is possible to couple the design of the scaffold with controlled cell‐culture condition to modulate the behavior of the cells. However, this is just initial work, further development will be needed.

This method enables the designer to manipulate the scaffold at three different length scales, namely the macroscopic scale, intermediate scale and the cellular scale.

The work presented in this paper focuses on important processing steps for indirect scaffold fabrication using thermal‐sensitive natural biomaterial. A mathematical model is proposed to estimate the height of a printed line.

A comparative analysis of the results of two longitudinal studies conducted a decade apart, among research post-graduate students, with the purpose of understanding the progress in their information literacy (IL) skills, forms the content of this report. The analysis is based on the application of the Research and Information Search Expertise (RISE) model, which traces students’ progression across four stages of expertise. Such progression was measured across two dimensions of knowledge: that of information sources/databases and that of information search skills. Both studies adopted basic interpretive qualitative methods involving direct observation, interviews, think-aloud protocols, and survey questionnaires, during each of the five interventions, which were spread over a one to one-and-half year period. Scaffolding training was provided at each meeting and data were collected to assess the influence of such training on development of search expertise. A comparison of the findings reveals that students in both studies advance in their IL skills largely in a similar manner. Scaffolding support was found to help both dimensions of knowledge and that lack of one or the other type of knowledge could hinder their ability to find relevant sources for their research. The studies make evident the need for training programs for higher education students, to improve both their knowledge of information sources and their search techniques, tailor-made to closely correlate to their specific information needs. The studies provide insights into student behaviors in the development of IL skills, and the RISE model offers a framework for application to other similar research.

This paper uses a probit model to analyse 100 observations in terms of three hypotheses about the formation of owners’ corporations in high‐density private housing estates in Hong Kong within the context of Mancur Olson’s group theory. The findings do not reject the theory, revealing that it is more likely for an older urban estate with fewer owners to form owners’ corporations. The discussion includes a brief introduction to Olson’s group theory and the development of the probit analysis. Some speculative thoughts about public participation in local level urban management and planning are offered in the conclusion.

The paper aims to explore the extent to which the legal experience of minority shareholder actions in Hong Kong supports the sociological model of the Chinese family firm as developed by Wong Siu‐lun and reports some preliminary findings for the period 1980‐1995.

This paper is based upon the analysis of 275 minority shareholder petitions in the High Court of Hong Kong between the years 1980 and 1995 inclusive. It also draws upon material from a questionnaire sent to law firms involved in those petitions and interviews with members of the Hong Kong judiciary with experience of hearing minority shareholder cases, members of the legal profession and accounting and company secretarial professions directly or indirectly involved in the administration of companies in Hong Kong and regulators.

The findings indicate that the problematic early, emergent stage of the model as described by Wong Siu‐lun is quite accurate. Whilst there is considerable support for some aspects of the model of the Chinese family firm, the experience indicates a number of complex dynamics at play, some of which the model does not take into account. However, the findings, at least by implication, do point to the cohesive strength of the Chinese family firm with occasional fault lines resulting in some “disputes” of earthquake proportions which may rumble on in some cases for years.

The findings demonstrate the usefulness of lifecycle modeling of the family and other type of corporate firm. It also demonstrates some of the complex subtleties at play. The findings also have implications for the law matters thesis of La Porta et al.

This is one of the first studies to actually examine the legal experience of minority shareholder protection in a particular jurisdiction (Hong Kong) by examining the petitions and writs actually filed and relating them to a sociological model of the Chinese Family firm.

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.

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.

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.

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.

The purpose of this paper is to compare and analyse the role and implementation of nationalistic education in Hong Kong and Macau special administrative regions (SARs) since their respective handover of sovereignty to China in the late 1990s. Both SARs face the educational need to cultivate a Chinese national identification among the students after the sovereignty changes. While Macau SAR has enjoyed a relatively smooth implementation of nationalistic education towards which Macau’s schools and students are largely receptive to nationalistic programmes since its handover in 1999, Hong Kong SAR Government’s nationalistic education was met by reservation from some parents, students and civil society’s groups under allegations of “political indoctrination” and “brain-washing”. The Hong Kong civil society’s resistance to National Education culminated in the anti-Moral and National Education protest in Summer 2012 and then Hong Kong schools and society. This paper attempts to provide an overview and analysis on the development of nationalistic education in both Hong Kong and Macao SARs, and to give some possible explanations on the factors that lead to differences of perceiving and responding to the nationalistic education between both places.

After conducting a literature review, this study utilises different sources of data such as curriculum guidelines, previous studies and other scholarly findings in examining the development of civic education and national education policy in both SAR societies, as well as in discussing the possible developments of nationalistic education in both SARs by making references to previous studies of citizenship and nationalistic education.

This study found out that different relationships between the two SAR Governments and their respective civil society, the extent of established socio-political linkages with China, as well as the introduction of a core subject of Liberal Studies in Hong Kong secondary schools, which emphasises on multiple perspectives and critical thinking skills, are some plausible factors that explain different stories and developments of implementing nationalistic education in Hong Kong and Macao SARs.

For giving suggestions for a nationalistic education in both Chinese SARs, first, there should be an exploration of multiple citizenship identities. This will allow people to choose their identities and thus facilitate their belongingness in terms of local, national and global dimensions. In addition, there should be an exploration of a Chinese national identification with different emphases such as knowledge orientation and critical thinking so as to cater for youth values. Promoting the idea of an informed and reasonable-in-thinking patriot could also be a way to ease the concern that building a national identity negates a person’s freedom of thinking.

This paper attempts to compare and analyse the different responses to the same policy of enhancing nationalistic education development in both Hong Kong and Macao SARs of China. Some plausible explanations were given based on political, social and educational factors, as well as youth value oritentations. This paper would be an attempt to show that a top-down single-minded orientated nationalistic education may not work well a society such as Hong Kong, where civil society and youth values are quite different than that can be found in China.

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

The purpose of this paper is twofold: first to carry out a comprehensive literature review for state of the art regarding airline schedule planning and second to identify some new research directions that might help academic researchers and practitioners.

The authors mainly focus on the research work appeared in the last three decades. The search process was conducted in database searches using four keywords: “Flight scheduling,” “Fleet assignment,” “Aircraft maintenance routing” (AMR), and “Crew scheduling”. Moreover, the combination of the keywords was used to find the integrated models. Any duplications due to database variety and the articles that were written in non-English language were discarded.

The authors studied 106 research papers and categorized them into five categories. In addition, according to the model features, subcategories were further identified. Moreover, after discussing up-to-date research work, the authors suggested some future directions in order to contribute to the existing literature.

The presented categories and subcategories were based on the model characteristics rather than the model formulation and solution methodology that are commonly used in the literature. One advantage of this classification is that it might help scholars to deeply understand the main variation between the models. On the other hand, identifying future research opportunities should help academic researchers and practitioners to develop new models and improve the performance of the existing models.

This study proposed some considerations in order to enhance the efficiency of the schedule planning process practically, for example, using the dynamic Stackelberg game strategy for market competition in flight scheduling, considering re-fleeting mechanism under heterogeneous fleet for fleet assignment, and considering the stochastic departure and arrival times for AMR.

In the literature, all the review papers focused only on one category of the five categories. Then, this category was classified according to the model formulation and solution methodology. However, in this work, the authors attempted to propose a comprehensive review for all categories for the first time and develop new classifications for each category. The proposed classifications are hence novel and significant.

The pressure to survive in a highly competitive market by using artificial intelligence (AI) has further demonstrated the need for automation in business operations during a crisis, such as COVID-19. Prior research finds managers' mixed perceptions about the use of technology in business, which underscores the need to better understand their perceptions of adopting AI for automation in business operations during COVID-19. Based on social exchange theory, the authors investigated managers' perceptions of using AI in business for effective operations during the COVID-19 pandemic.

This study collected data through a survey conducted in China (N = 429) and ran structural equation modeling to examine the proposed research model and structural relationships using Smart PLS software.

The results show that using AI in supply chain management, inventory management, business models, and budgeting are positively associated with managers' satisfaction. Further, the relationship between managers' satisfaction and effective business operations was found to be positively significant. In addition, the findings suggest that top management support and the working environment have moderating effects on the relationship between managers' satisfaction and effective business operations.

The results of this study can guide firms to adopt an AI usage policy and execution strategy, according to managers' perceptions and psychological responses to AI.

The study can be used to manage the behavior of managers within organizations. This will ultimately improve society's perception of the employment of AI in business operations.

The study's outcomes provide valuable insights into business management and information systems with AI application as a business response to any crisis in the future.
