Abstract
Purpose
This paper seeks to provide an insight into the design and development of the thermal test model (TTM) of X‐Sat, a 120 kg class micro‐satellite, being developed at the Centre. This model was specifically constructed for carrying out a thermal balance test (TBT) in a 4 m diameter vertical thermal vacuum chamber.
Design/methodology/approach
The construction of the thermal model followed a structural mock‐up model which was modified thermally to suit the purpose. Specific and careful consideration was given to the geometry and, more importantly, thermal characteristics such as thermal mass, surface properties, etc. to mimic the actual satellite configuration as closely as possible. Test plans were devised to qualify the fabricated components to meet the out‐gassing and other thermal requirements for the model. Design and qualification of supporting frame and linkages for TBT are also covered.
Findings
It is possible to simulate the thermal characteristics of a micro‐satellite in orbit under a different mission scenario through proper scaling and using alternative material options while developing TTM.
Originality/value
The paper discusses in detail the simplified cost‐effective approach of constructing TTM and also outlines the various issues to be considered for a TBT. It provides valuable information needed for micro‐satellite designers.

This study aims to investigate the impact that knowledge management (KM) capabilities have on school effectiveness in career and technical education (CTE) in Taiwan.
Abstract
Purpose
This study aims to investigate the impact that knowledge management (KM) capabilities have on school effectiveness in career and technical education (CTE) in Taiwan.
Design/methodology/approach
The study adopted a survey research. A total of 439 valid samples were obtained and subsequently verified with structural equation modeling.
Findings
The results indicated that KM capabilities consist of two main dimensions, namely, the KM enabler capabilities and the KM process capabilities. The former includes structures, cultures and information technology support, whereas the latter includes acquisitions, storage, sharing and applications. In terms of the relationships among the dimensions of the model structure, the KM enabler capabilities managed to effectively predict the KM process capabilities, and the KM process capabilities managed to effectively predict the perceived school effectiveness.
Research limitations/implications
Based on the results, improvement of the KM enabler capabilities and process capabilities of higher education institutions of CTE is recommended so that their school effectiveness may be improved. Because the participants were not randomly selected, the generalizability of the results should be further examined.
Practical implications
This study encourages practitioners to focus their KM practices on KM enabler capabilities and the KM process capabilities.
Originality/value
The current study provided an insight into and further understanding of the model regarding the relationships among the KM enabler capabilities, the KM process capabilities and the school effectiveness.

Abstract
Purpose
The purpose of this paper is to explore the phenomena of Apple iPhone jailbreaking, a novel scenario where a company actively oppresses and discourages the co-creation of value and customisation of its products by loyal consumers.
Design/methodology/approach
This paper conducted a qualitative content and thematic analysis of online jailbreaker discourse to understand the motivations and reasons driving consumers to resist a brand to which they remain extremely loyal.
Findings
Three themes explain jailbreaker motivations: enhanced experience, individual right of self-expression and anti-hegemony. Further two themes explain the differing motivations driving hacktivists to create the “exploits” that are subsequently used by jailbreakers (liberating the masses; status and notoriety). Finally, an integrative conceptual model is provided to showcase how disparate theories of consumer behaviour are synthesised during this novel phenomena.
Originality/value
In contrast to previous work, the consumer activists featured in this paper are devoted to the brand and product they are resisting. Rather than switching to an alternative brand, these jailbreakers and hacktivists remain loyal to the product in a genuine effort to help the brand. Even more interesting is the brand actively oppressing these loyal consumers’ attempts to modify and, in some cases, improve their products. Overall, this paper highlights the contradictory relationship between Apple and some of its consumers and demonstrates how brand loyalty, dissatisfaction, resistance/activism and co-creation can co-exist within the same consumer–brand relationship.

Abstract
Purpose
The purpose of this paper is to trace the development of school autonomy and accountability and related multiple changes and impacts in key areas of school education in Hong Kong since implementing school-based management (SBM) from 1990s.
Design/methodology/approach
To explore the evolution and the uniqueness of autonomy and accountability in the Hong Kong school system, the paper begins with an historical account, followed by an evaluation of the effects of SBM as shown in policy documents, local research, international reviews and illustrative findings from a case study. The local and international implications of SBM for research and practice are then discussed.
Findings
This paper shows the links between school autonomy and accountability by exploring the potential effects of both of these factors on educational management and student achievement, which are increasingly emphasised in educational policies. The investigation shows that the assumed links and effects are not always consistent or empirically supported. The positive effects that school autonomy has on school governance and management, teachers’ work, school-based curriculums and student learning are all significant when there is also strong leadership, comprehensive continuous professional development and a positive, collaborative school climate. These key elements work alongside school autonomy to facilitate positive change.
Research limitations/implications
School autonomy and accountability should be viewed as necessary, but not sufficient, conditions for school improvement and development. Further characterisation of the processes happening in schools is needed to explore the different realisations of school autonomy and accountability.
Originality/value
This investigation of school autonomy and accountability in Hong Kong provides the international audience with a deeper understanding of the dynamics involved in the development of SBM.

Abstract
In this chapter, the author compares two representations of the child from two famous films by the Fifth Generation’s top director in China, Chen Kaige, Yellow Earth (1984) and Together (2002). The girl’s story in the former and the boy’s story in the latter show respectively the dissolution of the Party/state as an extended family home, and it being replaced by the atomized, fluid, and flexible family home in the new state-led neo-liberal order. Compared with the girl, the boy in the new century tries to convey an equally lyrical articulation of the family/home, but differently, with a strong sense of his subjectivity. Thus, the boy’s voice in Together, self-reflective, artistically innovative, and affective, becomes a voice of resistance against authoritarian neoliberalism in post-socialist China.

Abstract
Purpose
The purpose of this paper shows the effect of hot and humid weather conditions (HHWCs) on workers that has resulted in considerable loss in the construction industry, especially during the hottest periods due to decline in worker productivity (WP). Until the last few decades, there is very limited research on construction WP in HHWCs. Nevertheless, these studies have sparked interests on seeking for the most appropriate methods to assess the impact of HHWCs on construction workers.
Design/methodology/approach
This paper begins by reviewing the current measuring methods on WP in HHWCs, follows by presenting the potential impact of HHWCs on WP. The paper highlights the methodological deficiencies, which consequently provides a platform for scholars and practitioners to direct future research to resolve the significant productivity loss due to global warming. This paper highlights the need to identify the limitations and advantages of the current methods to formulate a framework of new approaches to measure the WP in HHWCs.
Findings
Results show that the methods used in providing real-time response on the effects of HHWCs on WP in construction at project, task and crew levels are limited. An integration of nonintrusive real-time monitoring system and local weather measurement with real-time data synchronisation and analysis is required to produce suitable information to determine worker health- and safety-related decisions in HHWCs.
Originality/value
The comprehensive literature review makes an original contribution to WP measurements filed in HHWCs in the construction industry. Results of this review provide researchers and practitioners with an insight into challenges associated with the measurements methods and solving practical site measurements issues. The findings will also enable the researchers and practitioners to bridge the identified research gaps in this research field and enhance the ability to provide accurate measures in HHWCs. The proposed research framework may promote potential improvements in the productivity measurements methods, which support researchers and practitioners in developing new innovative methods in HHWCs with the integration of the most recent monitoring technologies.

Abstract
Purpose
Although a number of studies have researched food firms’ unethical practices, the mechanisms used to prevent these practices remain underexplored from the perspective of corporate governance. As independent directors (IDs) have been viewed as a mechanism to deter corporate misconducts, the purpose of this paper is to investigate the influences of the ratio of IDs on the board, IDs’ industrial experience and their participation in corporate governance training courses on food firms’ unethical production practices.
Design/methodology/approach
This study is based on a sample of 239 firm-year observations in Taiwanese food industries. The Poisson model with fixed effects was used to test the research hypotheses.
Findings
The results show that board independence and IDs with food industry expertise were not effective in deterring food firms from unethical production practices. The expected monitoring function of IDs would only realize when they complete a sufficient number of corporate governance training courses. These courses can make IDs aware of their responsibilities and roles in governing firms.
Originality/value
This study is the first to identify the effects of corporate governance practices on food firms’ unethical production practices. The value of this study may provide food firms practical solutions that enable corporate executives to behave ethically.
