Abstract
Purpose
The purpose of this paper is twofold: first, to clarify what specific behaviors are involved in consumers' partial switching in mobile application (app) usage, and, second, to explore the common and differential motivations of these behaviors.
Design/methodology/approach
This paper specified two behaviors in consumers' partial switching in mobile app usage, trialing and combining behaviors, and conceptualized them as different types of variety seeking behaviors. A theoretical model contrasting intrinsic motivations and extrinsic motivations on the two behaviors was developed and tested with a sample of 561 mobile app users in China.
Findings
The findings showed that both trialing and combining behaviors could be motivated by intrinsic individual-related and extrinsic technology-related factors. Besides, intrinsic individual-related factors were more effective in motivating trialing behavior, whereas extrinsic technology-related factors were more effective in motivating combining behavior. All these findings are applicable and consistent in both hedonic and utilitarian apps.
Originality/value
This study extends and advances the literature on information technology switching by investigating consumer use behaviors from a new perspective of partial switching and multiple competing apps usage. This study also contributes to variety seeking literature by extending the understanding of variety seeking to the context of mobile app usage. Finally, by investigating the associations and distinctions of trialing and combining behavior, this study not only helps to fully understand the partial switching but also enriches the understanding of different types of variety seeking behaviors.

Abstract
Purpose
The purpose of this paper is twofold: first, to explore the negative consequences of ubiquitous connectivity enabled by personal IT ensembles (PITEs) usage; and second, to investigate the gender differences in the adverse effects of ubiquitous connectivity.
Design/methodology/approach
This study employs a socio-technical approach to identify the technical and interpersonal dimensions of PITE-enabled ubiquitous connectivity and develops a theoretical model to investigate their stress-inducing effects based on the framework of technostress. Furthermore, the moderating role of gender is examined based on the social role theory. The authors test the model on a sample of 439 Chinese netizens.
Findings
Ubiquitous technical and interpersonal connectivity induce four stressors: information overload, communication overload, life invasion and privacy invasion. These stressors further lead to psychological exhaustion and reluctance to try new ITs. The ubiquitous technical connectivity exerts stronger effects on stressors for female users than male users, and interpersonal connectivity exerts a stronger effect for male users than female users.
Originality/value
This study primarily contributes to the small amount of research on PITE-enabled ubiquitous connectivity by considering ubiquitous connectivity from a socio-technical perspective and examining the stress-related effects and outcomes of both technical and interpersonal dimensions of ubiquitous connectivity. This study also provides valuable insights into the gender differences in the stress-inducing effects of the two dimensions of ubiquitous connectivity.

Abstract
Purpose
World Trade Organization (WTO) accession marked a new beginning for China's economic, legal and institutional reforms and rapid integration with the rest of the world. The purpose of this paper is to review China's post‐WTO transition experience, synthesize and update studies on China's pattern of trade and structural transformation, and provide both positive and negative lessons for other developing countries.
Design/methodology/approach
The paper has broadly reviewed the latest policy changes after China's WTO accession, and literatures on China's trade and economic development issues in order to understand the Chinese success and its speciality, and draw some useful lessons for both China's decision‐makers and other developing countries.
Findings
There are two main findings: first, market liberalization alone is not sufficient, and economic system reform and the liberalization are closely related and complement and promote each other. Second, experimentations via special economic zones (SEZs) and opening to foreign direct investment (FDI), which facilitated and supported cluster development and learning‐by‐doing, are needed for industrial upgrading and export competitiveness.
Originality/value
The paper demonstrates the wisdom of China's simultaneous pursuit of domestic economic system reform, and opening to the international market. However, China has also paid a high social and environmental cost for its rapid growth. It is important for developing countries to have an exclusive, balanced and sustainable strategy in the future development.

Abstract
Purpose
The purpose of this study is to evaluate the tannase-assisted extraction of tea stem pigment from waste tea stem, after which the stability of the purified pigment was determined and analyzed.
Design/methodology/approach
The extracting process was optimized using the response surface methodology (RSM) approach. Material-liquid ratio, temperature and time were chosen as variables and the absorbance as a response. The stability of the tea stem pigment at the different conditions was tested and analyzed.
Findings
The optimized extraction technology was as follows: material-liquid ratio 1:20 g/ml, temperature 50°C and time 60 min. The stability test results showed that tea stem pigment was sensitive to oxidants, but the reducing agents did not affect it. The tea stem pigment was unstable under strong acid and strong alkali and was most stable at pH 6. The light stability was poor. Tea stem pigment would form flocculent precipitation under the action of Fe2+ or Fe3+ and be relatively stable in Cu2+ and Na2+ solutions. The tea stem pigment was relatively stable at 60°C and below.
Originality/value
No comprehensive and systematic study reports have been conducted on the extraction of pigment from discarded tea stem, and researchers have not used statistical analysis to optimize the process of tannase-assisted tea stem pigment extraction using RSM. Additionally, there is a lack of special reports on the systematic study of the stability of pigment extracted from tea stem.
