  • Antecedents and double-edged sword effect of amoral management in organizations

    Subjects: Management Science >> Development and Management of Human Resources submitted time 2023-10-26

    Abstract: Why do leaders in practice do not respond to the ethical components of business situations? How do subordinates react to this kind of leadership style? Drawing on the individual-situation interactionist perspective, and based on the situational strength theory, this study explores the antecedents and generation mechanism of amoral management. In addition, based on the social information processing theory and instrumental-ethical cognition framework, this study explores the double-edged effects of amoral management on individual and team’s work performance, as well as identifies the situational conditions of amoral management from the perspectives of high-performance expectation and perceived leader bottom-line mentality. This study provides theoretical contributions and practical implications regarding amoral management as an important yet understudied ethics-based leadership style.
     

  • 八棱海棠种子超低温保存中含水量对糖代谢的影响

    Abstract: Water content is a key factor influencing the seed cryopreservation, but its effecting mechanism is not fully understood. In order to provide theoretical basis for further improving the seeds viability after cryopreservation, the effect and way of water content on the viability of seed cryopreservation were explored. Malus � robusta seeds with different water contents were obtained by silica gel. The seed viability, sugar content and related enzyme indexes before and after cryopreservation were measured and correlation analysis were done. The results were as follows: (1) After 15 days of cryopreservation, the viability of seeds with different water contents was different, and the viability of seeds showed a trend of increasing and then decreasing as the water content of seeds decreased, and the seeds with 9.02% water content had the highest germination rate, at 53.33%. But after 120 days of cryopreservation, the viability of seeds increased as the water content decreased, and the seeds with 6.40%water content got the highest germination rate, at 27.78%. This indicates that the water content of Malus � robusta seeds has a significant effect on the viability after cryopreservation. It is affected by the storage time in liquid nitrogen, and the optimum water content decreases as the storage time extended in liquid nitrogen. (2) Correlation analysis showed that water content was significantly negatively correlated with viability, both water content and viability were correlated with sucrose and fructose content, acid invertase was correlated with water content, viability, sucrose and fructose, and fructokinase was correlated with viability, suggesting that water content affects the content of sucrose and fructose through effecting the activity of acid converting enzymes, which in turn affects sucrose metabolism to respond to low temperature and dehydration stress, ultimately leading to differences in viability. The seed viability is also affected by fructose metabolism through fructose kinase. Besides, alginate is one of the important regulatory substances of Malus � robusta seeds in response to water and low temperature stresses. In summary, water content has a significant effect on the viability of Malus � robusta seeds cryopreservation through the combined effect of sucrose and fructose metabolism. This study provides a theoretical reference to further explore the cryopreservation mechanism of seed.

  • 中国跨国公司外派人员多目标主动行为的前因与后果——挑战性-阻碍性压力视角

    Subjects: Psychology >> Developmental Psychology submitted time 2023-03-28 Cooperative journals: 《心理科学进展》

    Abstract: Prior research has highlighted the obstructive rather than motive role of cross-cultural stressors in expatriate success. The present research attempts to explore the reasons why Chinese multinational companies (MNCs) succeed or fail in international assignments. Based on the stress-motivation-behavior- outcome framework, this research focuses on the antecedents and outcomes of proactive behaviors of expatriates. To be specific, by drawing on self-determination theory and job demand-resource (control) model, our research links challenge-hindrance stressors to proactive behaviors of expatriates. Further, the research examines the motivation mechanisms of how these two different types of stressors influence proactive behaviors, and identifies the boundary conditions of these mechanisms from the perspectives of organization and job resources. In addition, our research also explores the impacts of proactive behaviors on multi-level expatriate outcomes as well as identifies the boundary conditions for such impacts. Our work underscores the strategic value of proactive behaviors in the uncertain and complex cross-cultural context, and entails significant practical implications for MNCs to select, train, motivate, and retain internationalized talents.

  • 亲顾客偏离行为的顾客响应:基于道德情绪的理论模型

    Subjects: Psychology >> Social Psychology submitted time 2023-03-28 Cooperative journals: 《心理科学进展》

    Abstract: The acts of pro-customer deviance (PCD), which occurs in the service encounters where employees consciously deviate from the formal regulations of enterprises to help customers or safeguard the interests of customers have been widely observed. However, barely no divergent results were found on the impact of PCD on the customer's response. Therefore, utilizing the Stimulus-Organism-Response paradigm and taking dual moral attributes of PCD (e.g., altruistic motivation, deviation from the norms of organization) as the logical origin, this study develops a model examining the relationship among PCD, customer moral emotions and re-patronage intention. Specifically, according to the Cognitive Appraisal Theory, this study explores customers' moral cognitive evaluation of PCD as well as their complex moral emotional response to PCD. Moreover, based on the Differential Emotions Theory, this study examines the interaction effect among different types of moral emotions, the mediating effect of moral emotions on the relationship between PCD and re-patronage intention, and the moderating effect of customer's attribution of responsibility and service context on the PCD-moral emotions-re-patronage intention linkage. The present study not only provides new theoretical insights into PCD and moral emotions, but also offers valuable practical implications for service enterprises to take advantage of the positive effect of PCD.

    Abstract: Objective To investigate the effect of miR-101 on biological behaviors of colorectal cancer cell line SW620. Methods CCK-8 method, colony formation assay, cell cycle analysis and apoptosis analysis were applied to assess the effects of miR-101 on cell proliferation, invasion and apoptosis of SW620 cells. Results Over-expression of miR-101 in SW620 cells significantly suppressed the cell proliferation and attenuated the colony-forming ability of the cells. Flow cytometry showed that over-expression of miR-101 in SW620 cells caused obvious cell cycle arrest in G2/M and G1 phases, and significantly increased the cell apoptosis rate. Conclusion Over-expression of miR-101 can inhibit the proliferation, cause cell cycle arrest and promote apoptosis of colorectal cancer SW620 cells.
