- ItemCrawfish shell- and Chinese banyan branch-derived biochars reduced phytoavailability of As and Pb and altered community composition of bacteria in a contaminated arable soil.(2023-03-20) Gu S; Yang X; Chen H; Jeyakumar P; Chen J; Wang HGlobally, soil contamination with arsenic (As) and lead (Pb) has become a severe environmental issue. Herein, a pot experiment was conducted using pak choi (Brassica chinensis L.) to investigate the effects of biochars derived from crawfish (Procambarus clarkia) shells (CSB) and Chinese banyan (Ficus microcarpa) branches (CBB) on the phytoavailability of As and Pb, and bacterial community composition in soils. Our results showed that the application of CSB and CBB decreased the concentrations of DTPA-extractable Pb in soils ranging from 26.8 % to 28.8 %, whereas CSB increased the concentration of NH4H2PO4-extractable As in soils, compared to the control. Application of both biochars reduced the uptake of As and Pb in the edible part of pak choi. In addition, application of CBB significantly (P < 0.05) increased the activities of α-glucosidase, β-glucosidase, cellobiohydrolase, and acid phosphomonoesterase by 55.0 %, 54.4 %, 195.1 %, and 76.7 %, respectively, compared to the control. High-throughput sequencing analysis revealed that the predominant bacteria at the phyla level in both biochar-treated soils were Firmicutes, Proteobacteria, and Actinobacteriota. Redundancy and correlation analyses showed that the changes in bacterial community composition could be related to soil organic carbon content, As availability, and nutrient availability in soils. Overall, the Chinese banyan branch biochar was more suitable than the crawfish shell biochar as a potential amendment for the remediation of soils co-contaminated with As and Pb.
- ItemCross-cultural Issues on Organizational Dissent and Humor Orientation(Korean Association for Business Communication, 2018-07-31) Croucher S; Kelly S; Chen HOrganizational dissent is the expression of disagreement or contradictory opinions concerning organizational policies and practices (Kassing, 1998). It is an important form of communication because employees can give feedback to organizations regarding discontent and unethical practices. Thus, dissent provides organizations opportunities for improvement and innovation. Managers, however, often fail to recognize and respond to employees’ upward dissent. While power differences in organizations stifle communication, humor can be used as a form of dissent and a means to subvert power differences (Holmes & Marra, 2002). Research has explored organizational dissent in the United States. These results, however, cannot be applied to other contexts, as cultural differences should be considered when exploring communication (McCroskey & McCroskey, 1988). Thus, this analysis provides the following: First, this analysis provides a theoretical understanding of how humor and dissent relate to one another. Second, this analysis considers this relationship in divergent cultural contexts.
- ItemPolitical Background and Household Financial Asset Allocation in China(Taylor & Francis (Routledge), 2021-01-18) Ge Y; Chen H; Zou L; Zhou ZPolitical background is an important factor in determining the household economic behavior. Using 2014–2018 households panel data from the China Family Panel Studies (CFPS), we investigate the effects of political background on China’s household asset allocation behavior. We find that political background has a significant positive impact on the financial market participation. Mediation analysis indicates that political background leads to higher household wealth, better social capital, and fewer credit constraints, thus promotes households investments. Further analysis shows that the marginal impact of political background on household investment behavior is more significant in Eastern and urban areas. Our results contribute to the existing literature on the relationship between the political background and the household investment behavior, also enhancing the understanding of the household portfolio heterogeneity.
