This article combines arguments from entrepreneurship literature and social capital theory to examine the antecedents to the internationalization of small and medium‐sized enterprises (SMEs) from China. Our quantitative study of 117 Chinese SMEs demonstrates the overall importance of entrepreneurial orientation and social capital of entrepreneurs in facilitating their internationalization efforts, and also reveals that different dimensions of entrepreneurial orientation and different types of social capital exert different levels of independent influence on Chinese SMEs' internationalization. Complementary data from multiple case studies explains the variation between our quantitative findings and the findings of previous research. By highlighting the value of the entrepreneurial attributes of Chinese SMEs and the social capital embedded in their networks in the pursuit of their internationalization, the article adds to the scant literature on the internationalization behavior of the rapidly emerging Chinese SMEs. © 2012 Wiley Periodicals, Inc.

To overcome the costs of doing business abroad, researchers have suggested either legitimacy-or efficiency-based solutions. However, both types of solutions still treat host-country customers as external to the theory. We highlight the role of customers in the international professional business service setting and argue that customer involvement is positively related to the perceived internationalization performance of multinational corporations (MNCs). MNCs with managers who perceive higher legitimacy pressures and greater needs for local knowledge tend to undertake greater efforts to build customer involvement. Furthermore, we develop a configuration framework between perceived strategic needs and MNCs' capabilities. Specifically, MNCs that match relational capability with legitimacy needs and absorptive capacity with knowledge needs are more likely to engage in customer involvement. Our survey of 175 Chinese MNCs provides evidence that customer involvement is positively related to perceived internationalization performance. When MNCs' relational capabilities are stronger, the positive relationship between legitimacy pressure and customer involvement increases. By contrast, MNCs with greater perceived market ambiguity improve customer involvement only when they have stronger absorptive capacity. We conclude that MNCs may simultaneously reduce legitimacy and efficiency costs through customer involvement after considering the fit between perceived environmental pressures and firm capabilities.

An electroencephalogram (EEG) based brain-computer interface (BCI) speller allows a user to input text to a computer by thought. It is particularly useful to severely disabled individuals, e.g., amyotrophic lateral sclerosis patients, who have no other effective means of communication with another person or a computer. Most studies so far focused on making EEG-based BCI spellers faster and more reliable; however, few have considered their security. This study, for the first time, shows that P300 and steady-state visual evoked potential BCI spellers are very vulnerable, i.e., they can be severely attacked by adversarial perturbations, which are too tiny to be noticed when added to EEG signals, but can mislead the spellers to spell anything the attacker wants. The consequence could range from merely user frustration to severe misdiagnosis in clinical applications. We hope our research can attract more attention to the security of EEG-based BCI spellers, and more broadly, EEG-based BCIs, which has received little attention before.

The effects of surfactants addition on enzymatic hydrolysis and subsequent fermentation of steam exploded lodgepole pine (SELP) and ethanol pretreated lodgepole pine (EPLP) were investigated in this study. Supplementing Tween 80 during cellulase hydrolysis of SELP resulted in a 32% increase in the cellulose-to-glucose yield. However, little improvement was obtained from hydrolyzing EPLP in the presence of the same amount of surfactant. The positive effect of surfactants on SELP hydrolysis led to an increase in final ethanol yield after the fermentation. It was found that the addition of surfactant led to a substantial increase in the amount of free enzymes in the 48 h hydrolysates derived from both substrates. The effect of surfactant addition on final ethanol yield of simultaneous saccharification and fermentation (SSF) was also investigated by using SELP in the presence of additional furfural and hydroxymethylfurfural (HMF). The results showed that the surfactants slightly increased the conversion rates of furfural and HMF during SSF process by Saccharomyces cerevisiae. The presence of furfural and HMF at the experimental concentrations did not affect the final ethanol concentration either. The strategy of applying surfactants in cellulase recycling to reduce enzyme cost is presented.
