Summary: Soybean is one of the most economically important crops worldwide and an important source of unsaturated fatty acids and protein for the human diet. Consumer demand for healthy fats and oils is increasing, and the global demand for vegetable oil is expected to double by 2050. Identification of key genes that regulate seed fatty acid content can facilitate molecular breeding of high‐quality soybean varieties with enhanced fatty acid profiles. Here, we analysed the genetic architecture underlying variations in soybean seed fatty acid content using 547 accessions, including mainly landraces and cultivars from northeastern China. Through fatty acid profiling, genome re‐sequencing, population genomics analyses, and GWAS, we identified a SEIPIN homologue at the FA9 locus as an important contributor to seed fatty acid content. Transgenic and multiomics analyses confirmed that FA9 was a key regulator of seed fatty acid content with pleiotropic effects on seed protein and seed size. We identified two major FA9 haplotypes in 1295 resequenced soybean accessions and assessed their phenotypic effects in a field planting of 424 accessions. Soybean accessions carrying FA9H2 had significantly higher total fatty acid contents and lower protein contents than those carrying FA9H1. FA9H2 was absent in wild soybeans but present in 13% of landraces and 26% of cultivars, suggesting that it may have been selected during soybean post‐domestication improvement. FA9 therefore represents a useful genetic resource for molecular breeding of high‐quality soybean varieties with specific seed storage profiles. [ABSTRACT FROM AUTHOR]

Research Summary: Previous studies on initial public offerings (IPOs) in mature stock markets have documented that high‐reputation underwriters primarily work with high‐quality firms and vice versa—that is, they are paired through a quality‐matching mechanism. We propose that in a nascent stock market, a pricing mechanism may also play a role, through which pricing (the underwriting fee) sets the pairing. We examine these two mechanisms in the context of China's ChiNext stock exchange, which was launched in 2009 and experienced dramatic regulatory improvements in 2012–2013. With data on IPOs in 2009–2017, we find evidence to support the pricing mechanism's effect before the regulatory improvements and the quality‐matching mechanism's effect after the improvements. We contribute to the literature by developing an evolutionary view on the pairing mechanisms between important capital market participants. Managerial Summary: In a mature stock market, underwriter reputation signals the underlying quality of initial public offering (IPO) firms to external investors because high‐reputation underwriters primarily work with high‐quality IPO firms and vice versa. We find that in a nascent stock market before the market experiences regulatory improvements, underwriters and IPO firms are paired through a pricing mechanism. That is, underwriters with higher reputation charge higher underwriting fees, and IPO firms with lower quality pay higher fees. Since the pricing mechanism rather than the quality‐matching mechanism sets the pairing, underwriter reputation does not have a signaling effect. Instead, we find that higher underwriting fees signal lower quality of IPO firms. Our findings shed important insights on how market participants are paired in other nascent markets, nascent technology fields and industries. [ABSTRACT FROM AUTHOR]

The outbreak of coronavirus disease 2019 (COVID‐19) is having a dramatic effect on the mental health of healthcare workers (HCWs). Upon the emergence of the COVID‐19 pandemic, the Chinese government dispatched about 42 000 HCWs to Wuhan City and Hubei Province to fight this pandemic. This study briefly examines front‐line nurses who experienced burnout, with the main objective of investigating the mediating roles of positive and negative affect in the relationship between resilience and burnout in Wuhan hospitals at the peak of the COVID‐19 pandemic. A total of 180 front‐line nurses voluntarily participated via a social media group. They completed the online questionnaires, including the Maslach Burnout Inventory‐General Survey (MBI‐GS), the Positive and Negative Affect Schedule (PANAS), the Connor–Davidson Resilience Scale (CD‐RISC), demographics, and work‐related characteristics. Structural equation modelling (SEM) analysis was used to examine the mediating effect of positive and negative affect on the relationship between resilience and burnout. The total prevalence of burnout was 51.7%, of which 15.0% were severe burnout. These preliminary results revealed that positive and negative affect fully mediated the effects of resilience on burnout, emotional exhaustion, depersonalization, and reduced personal accomplishment of front‐line nurses. It is necessary to know the impact of resilience on HCWs with burnout through the positive and negative affect of individual backgrounds and situations, and how policymakers can deploy resilience interventions to support front‐line HCWs.

We evaluate the substitution effect between formal and informal institutions based on a natural experiment in China, i.e., the targeted reserve requirement ratio cut (TRRRC) policy. TRRRC creates a large and persistent discontinuity affecting loan availability for small and micro‐enterprises (SMEs) with sales below specific cut‐offs. Using the regression discontinuity design, we show that the trade credit of SMEs is significantly lower for firms with sales below the cut‐offs, indicating a substitution effect of banking loan on trade credit. Our findings are more pronounced for firms with poor product market performance, weak mortgage capability, young age, and poor financial environment. [ABSTRACT FROM AUTHOR]

In this study, we examine how intercommunity relationships affect the growth of organizational communities. Using a unique panel dataset on 53 technology development communities in China spanning 1988–2000, we found that regional community density, a community's geographic proximity to the nearest community and its domain overlap with the nearest community have an inverted U-shaped relationship with the community's growth. These non-monotonic results suggest that adjacent communities have both mutualistic and competitive effects on each other. Theoretical and managerial implications are discussed.

Drawing upon the resource-based view and transaction cost economics, this study aims to examine how various types of managerial resources (i.e., political networking and functional experience) can be beneficial to new ventures in a transition economy. Using survey data from a sample of new ventures in China's high-technology industries, we demonstrate that managers' political networking and functional experience are positively related to new venture performance. We also find that the positive relationship between functional experience and new venture performance is moderated by the type of ownership of the ventures and the level of dysfunctional competition in their environments. Theoretical and managerial implications are discussed. Copyright © 2007 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]
