I combined the broaden-and-build and job demands–resources theories, and examined the effect of employees' daily positive emotions outside the workplace before work on work engagement, and the mediating roles of (a) seeking resources and challenges and (b) reducing demands, in
this daily job-crafting relationship. I collected data from 103 medical staff daily for 5 days, resulting in 515 data points, and used a multilevel model for data analysis. Results show that positive emotions directly and positively predicted work engagement, and also predicted work engagement
indirectly and positively through seeking resources and challenges. Further, the effect of positive emotions was mediated by job crafting during the day through seeking resources and challenges, but not through reducing demands. These results emphasize the importance in subsequent work engagement
of employees' emotions experienced in their personal life.

Drawing on relative deprivation theory, we explored the mechanism for the influence of coworker knowledge hiding on employee job crafting and the moderating role of supervisor developmental feedback from the perspective of status competition. Thus, we tested the tripartite interpersonal
interactions among knowledge-hiding individuals, knowledge-seeking employees, and supervisors. We conducted a two-wave time-lagged study on 354 employees who worked for Chinese owned and operated companies in China. We found that there was an inverted U-shaped relationship between coworker
knowledge hiding and employee job crafting, in which an employee's sense of relative deprivation played a mediating role. Furthermore, supervisor developmental feedback negatively moderated the relationship between coworker knowledge hiding and an employee's sense of relative deprivation.
To increase the level of employee job crafting, managers should pay attention to the degree of employeeâ–™s sense of relative deprivation and attempt to moderate that by providing supervisor developmental feedback.

AbstractThe application of biomass energy is one of the important ways to achieve carbon neutrality and deal with global warming. The study on the combustion mechanism of anisole, an oxygen-containing fuel, is helpful for biofuel large-scale application. In this study, the soot formation and laminar combustion characteristics of anisole were analyzed by reactive force field molecular dynamics (ReaxFF MD) and kinetic simulation, respectively. ReaxFF MD simulation studies had shown that soot formation of anisole combustion occurred in three stages, stage 1 (0–1 ns), stage 2 (1–2.5 ns), stage 3 (2.5–6 ns). The three stages represented the pyrolysis of the fuel, the developmental stage of the soot, and the graphitization stage of the soot, respectively. During the combustion of anisole, primary mechanisms for the soot formation were as follows: H-abstraction-C2H2-addition, carbon-addition-hydrogen-addition, internal ring formation and long carbon chain link. The formation of soot graphitization exhibited different morphologically behaviors: from flakes to onions to spheres with fewer branched chains. From the study of the laminar combustion characteristics of anisole, it can be found that the laminar burning velocities increased along with the increase of temperature, while the opposite trend was shown along with the increase of pressure. The sensitivity coefficient of naphthalene, the main soot precursor, revealed that the main promotional reactions for soot formation were R5 (O2 + H <  =  > O + OH), R36 (CO + OH <  =  > CO2 + H).
