Search

As an important strategic decision for enterprise sustainability, the green entrepreneurial orientation can facilitate boundary-spanning search for external knowledge and resources to achieve triadic sustainable economic, environmental, and social performance. Based on organizational search theory and dynamic capability theory, this study introduces environmental dynamism into the model of the relationship between green entrepreneurial orientation, boundary-spanning search and enterprise triadic sustainable performance. By analyzing the questionnaire data from 202 managers of manufacturing SMEs, the study explores the internal and external influences of green entrepreneurial orientation on the enterprise sustainable performance. The results show that: green entrepreneurial orientation has a positive impact on enterprise economic, environmental and social performance; boundary-spanning search plays a fully mediating role between green entrepreneurial orientation and enterprise economic, environmental and social performance; environmental dynamism, as a key external environmental factor, positively regulates the relationship between boundary-spanning search and enterprise economic performance and environmental performance, and negatively regulates the relationship between boundary-spanning search and social performance. This study clearly demonstrates how green entrepreneurial orientation in the environmental era can drive triadic sustainable performance improvement of enterprises. In addition, this study argues that boundary-spanning search is an important tool that enables manufacturing SMEs to achieve a triad of coordinated sustainable development of economic, environmental and social benefits in a dynamic environment.

The increasing uncertainty of our world raises important questions for university students on how they should respond to the employment challenges caused by changing environments. One of the central topics is the development of graduate employability. However, most previous research on graduate employability was undertaken in a stable environment, limiting our understanding of how graduate employability develops in a dynamic context. We have advanced the literature by introducing action theory to investigate the process of personal initiative affecting graduate employability in a period of environmental uncertainty. Using a time-lagged research design, we collected data from a sample of 229 Chinese university students and tested the hypothesized relationships. We find that personal initiative positively affects graduate employability through human and psychological capital. We further show that environmental uncertainty plays a contingent role in the above processes. Specifically, when a high level of environmental uncertainty is perceived, the positive indirect effect of personal initiative on graduate employability through either human capital or psychological capital is more likely to be strengthened. The theoretical and practical implications of these findings are also discussed.

The aroma components of white tea from the new tea strain ‘Baiyun 0492’ (also known as Baiyun Tezaocha) and ‘Fuyun 6’ as a control were analyzed and compared by headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) in an effort to identify the characteristic aroma components of ‘Baiyun 0492’ white tea. A total of 928 aroma compounds were detected in six white tea samples (of three different grades for each type), and nonyl acetate, contributing to floral and fruity aromas, might be an aroma compound unique to ‘Baiyun 0492’ tea. The results of relative odor activity value (ROAV) analysis showed that β-ionone, linalyl acetate, linalool, (Z)-decan-2-enal, damascenone, neral and citral were the key aroma components in both white teas. Based on orthogonal partial least squares-discriminant analysis (OPLS-DA), the contents of linalool, methyl benzoate, hotrienol, nonyl acetate, 3,7-dimethy-6-actenoic acid and geranyl formate in ‘Baiyun 0492’ tea were significantly higher than those in ‘Fuyun 6’ tea (variable important in the projection (VIP) >1, P < 0.05). Linalsol and methyl benzoate were important aroma compounds of ‘Baiyun 0492’ white tea, responsible for pekoe-like, fruity and floral aromas. This study is helpful for a comprehensive understanding of the aroma characteristics of ‘Baiyun 0492’ white tea, and provides a scientific basis for the research and development of ‘Baiyun 0492’ white tea products with distinctive personality.
