Abstract
Purpose
Existing research on collaborative innovation mechanisms from the perspective of global operation is very limited. This paper aims to address the research gap by studying the factors influencing globally distributed teams’ innovation performance, especially how effective knowledge sharing between distributed teams promotes collaborative team innovation.
Design/methodology/approach
This research proposes a model to investigate how collaborative knowledge sharing affects global operations [team dispersion, task orientation, information and communication technology (ICT) usage] and innovation performance based on the data collected from 167 managers in 40 local Chinese IT and offshoring firms. Using the theory of Cognitive Diversity and Innovation Diffusion and Synergy, separate hierarchical regression analysis was used to test the proposed model.
Findings
The findings of this study demonstrate that effective collaborative knowledge sharing plays a crucial role in enhancing innovation performance in a global operation. Specifically, innovation capacity can be improved by task orientation, ICT usage and team dispersion.
Originality/value
This research study contributes to the development of global distributed operations and innovation among distributed teams in multinational corporations.

Abstract
Purpose
Despite the increasing relevance of seamless shopping experience in an omnichannel context, research on how seamless shopping experience affects customers’ word of mouth on social media (sWOM) remains scant. Based on the attribution theory, this study aims to investigate the effects of seamless shopping experience types on customers’ sWOM intentions from the perspective of smart-shopping feelings and validated the moderation role of shopping orientation.
Design/methodology/approach
Using a data set of 301 omnichannel customers, three scenario-based experiments were conducted to address the research questions.
Findings
An efficient and interconnected experience is more likely to positively affect sWOM intentions than an inefficient but interconnected experience. Furthermore, smart-shopping feelings were found to have a significant mediating effect. For experiential-oriented shoppers, the positive relationship between an efficient and interconnected experience, smart-shopping feelings and sWOM intentions was significantly strengthened.
Originality/value
This research contributes to the sWOM and omnichannel service experience literature by investigating the influences of seamless shopping experience types on customers’ sWOM intentions. This research also provides recommendations for designing and delivering a superior, seamless shopping experience for omnichannel shoppers.

Abstract
In the second half of 2003 and the first half of 2004, the Chinese Government adopted a moderately tight macroeconomic policy, which aroused widespread attention from home and abroad. This is because China's deepening of reform and openness has led to its increasing economic links with the outside world. Starting from analysing the characteristics of the Chinese economy in 2003, this article discusses the issue of contractive macroeconomic regulation. The article highlights that the growth of the Chinese economy in 2003 has two features. One is that China 's per capita gross domestic product (GDP) exceeded US$1 ,000, which indicates the Chinese economy may possibly maintain the momentum for rapid growth for a fairly long period. The second is that its year-to-year GDP growth reached 9.3 per cent, putting an end to the continual sliding trend of the economy between 1993 and 1999. It also put a stop to the Chinese economy's continual sluggish growth of between 7 and 8 per cent between 1998 and 2002, in the wake of the Asian financial crisis. The Chinese economy has embarked on a fast track in the new round of the economic cycle. However, in the third and fourth quarter of 2003 and the first quarter of 2004, China's GDP growth was as high as 9.6, 9.9 and 9.8 per cent, respectively, sparking a supply crisis in the coal, power, fuel and transportation sectors. As a result, important raw materials, such as steel and cement, faced a supply bottleneck and price inflation pressures intensified, Consequently, the Chinese Government, in a timely move, has adopted a moderately contractive macroeconomic policy to prevent the economy from fluctuating drastically and to avoid serious inflation to ensure a rapid, stable and sustainable economic growth. This is not only conducive to the growth of the country's economy itself, but also favorable for the development of the international trade and foreign investment in China.

Abstract
To explore how student teachers (re)construct their professional identities, this chapter contextualizes two student teachers’ practicum experiences in China. The overarching question is how the student teachers (re)construct their professional identities in the practicums, especially where their teacher knowledge and subject matter knowledge meet. By analyzing a flexible matrix of paired stories, the research highlights the collective influences of the multiple instructional contexts: nation-wide Free Teacher Education program policy, recent national curriculum reform in China, and the characteristics of the placement schools. The chapter finds that the student teachers’ professional identities are dynamic and evolving on the professional knowledge landscape. The (re)construction of professional identities involves developing practical knowledge and metaphors by negotiating the tensions the student teachers encountered in the practicums. Meanwhile, the student teachers experienced reflective turns (Schön, 1991) in the practicums, which caused the tension between teacher knowledge and subject matter knowledge and contributed to the formation of their professional identities.

Abstract
Purpose
In response to increasing demand for a fully customized and individualized home environment, mass customization (MC) has been suggested as an effective strategy to fulfill the customer’s customization needs while keeping production cost-effectiveness. However, in current practice, the implementation of the MC in the industrialized housing industry has not achieved an ideal level. Little effort was devoted to customer value generation and achieving lean production in a multi-disciplinary MC environment. In this concern, a highly efficient and flexible production information system is expected to capture accurately the customer’s demand and efficiently perform work planning for encouraging customer involvement and mass efficiency production.
Design/methodology/approach
To gain an insight into the development of the MC production information system for the housing industry and to depict the interaction among system modules, this study used a design science research methodology for a case study of customized cabinet production information system development.
Findings
A prototype of the production information system was proposed in this paper, supported by three information technologies to facilitate the MC implementation in the millwork manufacturer. A focus group discussion method was carried out for evaluating the system feasibility and the subsequent survey analysis on the virtual reality (VR) interface experiment. The evaluation process results showed that the VR interface is an effective medium for design information communication and encourages customer involvement. Most participants believed that the proposed production information system could generally benefit the MC implementation and improve production efficiency.
Originality/value
This study integrated lean production principles along with building information modelling, VR and discrete-event simulation in the production information system to assist the manufacturer in effectively handling variant product information and enabling quicker reactions in response to diverse customer requirements in housing industries. The coordination among system modules and the managed information flow could be a valuable reference for future MC production system development in housing industries.

Abstract
Purpose
This paper aims to explore the adsorption kinetics of syringin from Syringa oblata Lindl. leaves on macroporous resin and develop an efficient, simple and recyclable technology for the separation and purification of syringin.
Design/methodology/approach
Static adsorption and desorption properties of six resins were tested to select a suitable resin for the purification of syringin. Langmuir and Freundlich isotherm models were used to estimate the adsorption behavior of syringin on AB-8 resin. Breakthrough point and eluent volume were determined by dynamic adsorption and desorption tests. High-performance liquid chromatography-electrospray ionization-mass spectrometry was applied to identify the syringin in the purified product [syringin product (SP)]. Antioxidant and antibacterial activities of SP in vitro were evaluated by free radical scavenging ability and biofilm formation inhibitory tests.
Findings
AB-8 exhibited the most suitable adsorption and desorption capacity. Adsorption isotherm parameters indicated favorable adsorption between AB-8 and syringin. The optimal results were as follows: for adsorption, the sample concentration was 1.85 mg/mL, the sample volume was 3.5 bed volume (BV), the flow rate was 0.5 mL/min; for desorption, the ethanol concentration was 70%, the elution volume was 2.5 BV, the elution velocity was 1.0 mL/min. SP with 80.28% syringin displayed the potent antioxidant activities and inhibitory effects on biofilm formation of Streptococcus suis.
Originality/value
To the best of authors’ knowledge, there are no reports on purifying syringin from Syringa oblata Lindl. leaves using macroporous resins. This paper may also provide a theoretical reference for the purification of other phenylpropanoid glucosides.

Abstract
Purpose
Laser cleaning, as a new type of cleaning technology, has the advantages of environment-friendliness, better selectivity, better controllability and higher efficiency compared to traditional chemical cleaning or grinding. This paper aims to use ultra-fast surface laser cleaning equipment built in laboratory to study the influence of different energy density (7.6, 11.5 and 15.3 J/cm2) on corrosion resistance of the aluminum alloy A7N01P-T4, a high-speed train body material.
Design/methodology/approach
SEM, white light interferometer, EDS and XPS were used to analyze the surface morphology, roughness, element content and oxide layer composition of aluminum alloy before and after cleaning. The corrosion resistance was studied by electrochemical experiments and exfoliation corrosion experiments.
Findings
The results showed that new oxide scale was formed on the surface after laser cleaning. The changes of surface roughness and chemical composition of oxide scale made a significant influence on corrosion behaviors. Better corrosion resistance was obtained with the energy density increased, and at the energy density of 11.5 J/cm2, aluminum alloy exhibited the best corrosion resistance.
Research limitations/implications
The paper only studies specific aluminum alloys and is not universal. Laser cleaning equipment is set up for the laboratory and has not yet been put into industrial production.
Practical implications
This paper indicated that ultra-fast laser processing was a new direction for the development of industrial equipment surface cleaning and carried out ultra-fast laser of aluminum alloy surface cleaning had certain research significance for its corrosion resistance.
Social implications
Compared with the conventional cleaning methods such as air abrasives grinding or chemical cleaning, laser cleaning has advantages of environment-friendliness, better selectivity, better controllability and higher efficiency. Laser cleaning can not only protect the environment, but also improve cleaning efficiency.
Originality/value
Changes in the surface of aluminum alloys after ultra-fast surface laser treatment were found, and the mechanism of changes in aluminum alloy corrosion properties was clarified.

Abstract
Purpose
Fixed mode noise and random mode noise always exist in the image sensor, which affects the imaging quality of the image sensor. The charge diffusion and color mixing between pixels in the photoelectric conversion process belong to fixed mode noise. This study aims to improve the image sensor imaging quality by processing the fixed mode noise.
Design/methodology/approach
Through an iterative training of an ergoable long- and short-term memory recurrent neural network model, the authors obtain a neural network model able to compensate for image noise crosstalk. To overcome the lack of differences in the same color pixels on each template of the image sensor under flat-field light, the data before and after compensation were used as a new data set to further train the neural network iteratively.
Findings
The comparison of the images compensated by the two sets of neural network models shows that the gray value distribution is more concentrated and uniform. The middle and high frequency components in the spatial spectrum are all increased, indicating that the compensated image edges change faster and are more detailed (Hinton and Salakhutdinov, 2006; LeCun et al., 1998; Mohanty et al., 2016; Zang et al., 2023).
Originality/value
In this paper, the authors use the iterative learning color image pixel crosstalk compensation method to effectively alleviate the incomplete color mixing problem caused by the insufficient filter rate and the electric crosstalk problem caused by the lateral diffusion of the optical charge caused by the adjacent pixel potential trap.

Abstract
Purpose
This study investigates how reward type (single vs. plural), reward characteristic (utilitarian vs. hedonic) and product involvement (high vs. low) affect the design of reward programs.
Design/methodology/approach
A 2 ✕ 2 ✕ 2 fractional factorial experimental design is constructed to explore the main factors influencing the effectiveness of reward programs on a sample of 436 Chinese customers.
Findings
The results indicate that reward type is an important determinant of customers' preference toward reward programs. Plural rewards are preferable to a single reward when the alternatives provide the same benefits, particularly in the low level of product involvement. In the high level of product involvement, reward characteristic has a significant effect on customers' preference. Hedonic rewards are more effective in building a program's value than utilitarian rewards. Moreover, reward characteristic interacts with reward type, positively impacting customers' preference toward reward programs.
Originality/value
This study suggests that managers should consider the effects of reward type, reward characteristic and product involvement to formulate attractive reward programs for sustainable business in China.
