Abstract
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.

Abstract
Polypyrrole (PPy)-coated fabric can be produced by means of chemical vapour deposition using pyrrole in the presence of an oxidizing agent. This electrically conductive fabric can be used as a strain sensor, and has high potential for producing wearable sensors that can detect the movements of the wearer. Since direct contact between this conductive fabric and human body will be involved, an investigation of the effect of different types of liquids such as sweat, rain water, drinking water, etc. on the electrical conductivity of fabric sensors is critical. Changes in the conductivity and surface morphology of the PPy-coated textile were analysed by placing few drops of liquid onto the fabrics. The results showed that the electrical resistance of the PPy-coated fabrics was different when the fabrics came into contact with different types of liquid. The phenomenon can be explained by both the fibre/fibre contact and yarn/yarn contact models as well as by the uniformity of the PPy-coating layer on the surface of the fibre.

Abstract
In recent years, the public awareness and concern for the environment have been increased significantly. This has resulted in tougher legislation and more stringent standards to which the industry will have to work. In this paper, the environmental regulatory situation in Hong Kong and the effluent standards in Hong Kong and other counties were reviewed so as to give a word of caution for the local textile dyeing industry. Moreover, various pollution prevention techniques were suggested in order to reduce pollution through elimination at the source rather than treatment or disposal.

Abstract
The analytic hierarchy process (AHP) method was used to determine the priority of processes outlined in the BS8800 Guide to Occupational Health and Safety Management Systems for the Hong Kong construction industry. Analysis of variance was used to further investigate the differences among three different kinds of construction enterprises: joint venture (JV), well‐established (W‐E) and small and medium sized (SME) enterprises. This study of 32 construction enterprises suggests that JV and W‐E enterprises are able to demonstrate stronger commitment to strategic safety issues whereas SMEs focus more on the short‐term safety issues in implementation of safety management system. The results also indicate that “Safety Training” may be a problem area in all three groups. When considering differences shown between groups, these rankings can be used as a guide for the practical implementation of the British Standard BS8800 Safety Management System in construction enterprises in Hong Kong.

Abstract
This paper looks at one relatively less‐visited issue in market timing: switching investments on common stocks between different stock markets, namely, “intermarket timing”. By employing the stock price data for the period of 1992‐2002 from a developed market, Hong Kong, and two emerging markets, Shanghai and Shenzhen, this paper examines potential gains and the required predictive accuracy for intermarket timing between Hong Kong and Shanghai, and between Hong Kong and Shenzhen from Hong Kong investors’ perspective. Potential gains could be obtained from such timing strategy, and the non‐high minimum forecasting ability required for successful timing is fairly attainable for Hong Kong investors, even after taking into account the assumed transaction costs.

Abstract
Purpose
The aim of this study is to investigate achievement profiles in mathematics when integers are taught in a learning study in grade three (to children 8–9 years old) and to explore to what extent students with such profiles participate in inclusive teaching and learning practices.
Design/methodology/approach
Data from a previous learning study are re-analysed, supported by a framework that enables the investigation of inclusive practices. In the present study, inclusion and achievement are viewed as interrelated, meaning that student achievement must be incorporated in the definition of inclusion. The analysis is based on documentation of a video-recorded lesson and on identical tests conducted before and after the lesson.
Findings
The general framing of the learning study indicates an inclusive practice, while pre- and post-test achievement together with data from the lesson reveal a mixed picture concerning student achievement and inclusion. The analysis of the pre- and post-test results for the 16 students in the class indicates considerable diversity in student achievement, resulting in four achievement profiles. The main conclusion is that some students gained from participating in the learning study lesson while others did not. The extensive analysis of four students' participation, one for each profile, shows that differences in student achievement are related to the extent to which students participate in inclusive teaching and learning practices.
Originality/value
While previous research on learning studies has mainly considered average student achievement, this study focuses on individual variation in achievement and the reasons for it, a matter largely neglected in previous learning study research.

Abstract
Purpose
To better understand the online reviews and help potential consumers, businessmen and product manufacturers effectively obtain users’ evaluation on product aspects, this paper aims to explore the distribution regularities of users’ attention and sentiment on product aspects from the temporal perspective of online reviews.
Design/methodology/approach
Temporal characteristics of online reviews (purchase time, review time and time intervals between purchase time and review time), similar attributes clustering and attribute-level sentiment computing technologies are used based on more than 340k smartphone reviews of three products from JD.COM (a famous online shopping platform in China) to explore the distribution regularities of users’ attention and sentiment on product aspects in this paper.
Findings
The empirical results show that a power-law distribution can fit users’ attention on product aspects, and the reviews posted in short time intervals contain more product aspects. Besides, the results show that the values of users’ sentiment on product aspects are significantly higher/lower in short time intervals which contribute to judging the advantages and weaknesses of a product.
Research limitations/implications
This paper cannot acquire online reviews for more products with temporal characteristics to verify the findings because of the restriction on reviews crawling by the shopping platforms.
Originality/value
This work reveals the distribution regularities of users’ attention and sentiment on product aspects, which is of great significance in assisting decision-making, optimizing review presentation and improving the shopping experience.

Abstract
Purpose
The purpose of this paper is to propose a new formulation of the overall equipment effectiveness (OEE) relying on the process approach (PA) in maintenance. This new indicator will be designated by OEE-TCQ.
Design/methodology/approach
Methodology followed in this paper is based on using two major parts. The first part deals with the use of time-driven activity-based costing (TDABC) and program evaluation and review technique (PERT) methods to formulate the temporal and financial components of the OEE-TCQ. The second part concerns the quality component formulation of OEE-TCQ by using the analytical hierarchy process (AHP) method and quality’s improvement (Six Sigma).
Findings
It is a new formulation of the OEE, based on the PA applied to operational maintenance processes, and also is interesting for improvement maintenance.
Practical implications
The new OEE-TCQ indicator can be used to support maintenance managers to have a three-dimensional analysis based on time, financial and quality criteria, also to improve time, cost and quality of each activity of maintenance operational processes.
Originality/value
This paper is one of few papers in maintenance proposing a new formulation of the OEE by using the combination of several methods especially TDABC, PERT, AHP and Six Sigma. It proposes in part a new quality evaluation approach for each activity of maintenance operational processes. Also, it suggests a new formulation for defects by millions of opportunities.

Abstract
One reason for the slow adoption rate of Electronic Fund Transfer at Point‐of‐Sale (EFTPoS) is that consumers perceive that EFTPoS has a higher level of risk than other traditional payment methods. Makes use of a concept in consumer behaviour and perceived risk to study the differences of consumers′ risk perceptions among alternative payment methods and whether these perceptions will be affected by the size of purchase and EFTPoS usage experience. The major findings are: (1) EFTPoS has the lowest physical risk and highest financial risk, the credit card has the lowest psychological risk and highest time loss risk, while cash has the highest physical risk and lowest performance risk; (2) Physical risk, financial risk and time loss risk for cash payment are significantly higher when the purchase is large, while performance risk for EFTPoS and credit card payment is significantly higher when the purchase is small; and (3) users of EFTPoS have a significantly higher level of perceived financial and time loss risk than non‐users, while non‐users have higher level of psychological risk. The overall finding is that the risk profile of EFTPoS is similar to that of the credit card but significantly different from cash.
