Purpose This study aims to fill three theoretical gaps in previous literature on exploration and exploitation: the relationship between exploration and exploitation is inconclusive; the influences of exploration and exploitation on firm performance are not consistent; and no empirical studies have integrated the antecedents of exploration and exploitation from the different research fields. Design/methodology/approach The study conducted a meta-analysis to quantitatively synthesize 143 studies with 257 independent samples to understand the relationship between exploration and exploitation and their consequences and antecedents. Findings The results show that exploration and exploitation are positively correlated with each other, and both of them can boost firm performance. Moreover, firm capabilities, firm size, firm age, competitive intensity, market orientation and entrepreneurial orientation positively influence exploration, and firm resources, firm capabilities, firm size, firm age, market orientation and entrepreneurial orientation positively influence exploitation. Competitive intensity negatively influences exploitation. Surprisingly, market turbulence does not significantly influence exploration or exploitation. Originality/value The results not only contribute to the theories by reconciling the inconsistent results but also provide insight for firms with guidance about under what conditions they should use what strategies.

Significance and Impact of the Study: Heat stable antifungal factor (HSAF) exhibits a potent and broad antifungal activity with a novel mode of action. Increased production and reduced cost of raw materials are particularly important for the future production of HSAF, however, no report was involved in these studies. This study aimed to improve the production of HSAF with cheap raw materials through the medium optimization, which would lay the foundation for the application of HSAF in biological control.

To help retailers gain consumers’ trust, many studies have investigated antecedents of consumer trust. However, distrust, a concept closely related to trust, has attracted only sporadic research attention. As a result, whether factors that increase consumer trust can eliminate consumer distrust is unclear. To deepen understanding of trust and distrust, this study applies the critical incident technique to identify and compare the antecedents of trust and distrust of Chinese consumers. The results show that the antecedents of distrust differ from those of trust, indicating different formulation mechanisms of both. Therefore, on the one hand, retailers should pay attention to increasing consumer trust, and on the other hand, they should develop marketing activities to reduce consumer distrust.

Human norovirus (HuNoV) is a major foodborne virus causing gastroenteritis outbreaks in humans. Salad products can be vectors of transmission for foodborne viruses such as HuNoV when these products are contaminated naturally or through unsanitary food handling. Therefore, development of simple, reliable and sensitive techniques for the detection of HuNoV in salad products is needed to ensure food safety. The purpose of our study was to optimize a method for the detection of HuNoV in artificially contaminated salad products. To this end, 2 different kinds of salads (fruit salads and vegetable salads) were experimentally inoculated with HuNoV GI, HuNoV GII, and MS2 suspensions. The selected method was based on treatment with pectinase followed by Trizol-chloroform purification, and the recovery efficiencies were 6.07% to 26.52% for HuNoV GI and 5.54% to 37.36% for HuNoV GII. MS2 was used as the process control, and the recovery efficiencies for fruit salad and vegetable salad samples were 38.57% and 41.13%, respectively. The optimized method could be applied in diagnostic laboratories to identify NoV contamination in composite foods, such as salad products, should an event of foodborne outbreak occur.
