Abstract

Emotional neglect is an under-recognized but relatively common type of childhood maltreatment. Although it has been reported that adolescents will facilitate positive growth after experiencing childhood maltreatment, such as sexual abuse, it is unknown whether adolescents could also get a promotion after experiencing emotional neglect. Thus, we aimed to examine the association between emotional neglect and posttraumatic growth (PTG) and further explored the potential influence factors underlying such association. Six hundred and thirty-five adolescents (55.2% female, M[subscript age] = 14.12 years old, SD = 1.47) were asked to complete self-report questionnaires regarding emotional neglect, school engagement, psychological suzhi, and PTG. Results showed that emotional neglect was negatively associated with PTG, and school engagement mediated such association. Further, psychological suzhi moderated the direct pathway from emotional neglect to PTG in which the deleterious effect of emotional neglect on PTG was weaker for adolescents who reported higher psychological suzhi. Meanwhile, psychological suzhi moderated the indirect pathway from emotional neglect to school engagement in the mediated model in which the deleterious effect of emotional neglect on school engagement was weaker for adolescents who reported higher psychological suzhi. Overall, the current study advances our understanding of the relationship between emotional neglect and PTG, and further tests the potential roles of school engagement and psychological suzhi in this relationship.

Abstract

The volatility impact and insufficient level of new energy accommodation brought by the high proportion of new energy connected to the grid have become an urgent problem to be solved under the background of new type power system. Therefore, based on the characteristics that the increase of prediction accuracy of wind, photovoltaic power and load improves step by step with reduced time scales and the flexible regulation ability of pumped storage plant, a multi-time scale coordinated dispatching model of wind-photovoltaic-pumped storage zero-carbon power system is established. In order to minimize the cost of power generation, the power generation plans of day-ahead 24-hour, the intraday 1-hour and the real-time 15-minute are established. Through the coordination of multiple time scales, the wind power, photovoltaic power and pumped storage output track the load well, thus revising the power generation plan step by step. Taking the wind-photovoltaic-pumped storage zero-carbon power system with 6 pumped storage units as an example, the simulation analysis shows that the proposed multi-time scale coordinated dispatching model is conductive to reducing curtailment of wind and photovoltaic power, and the ability of power system to accommodate wind and photovoltaic power is related to the installed capacity of pumped storage plant.

44. Effect of Cold Plasma on Meat Protein and Its Applications in Meat Processing and Preservation: A Comprehensive Review

Author

FAN Runze, QI Miao, ZHANG Xinying, PENG Sansan, ZHAO Xinyi, LI Zhuo, XU Dehui

Subjects

Abstract

Cold plasma is used to sterilize meat and reduce endogenous enzyme activity for meat preservation because it can generate reactive nitrogen species (RNS) and reactive oxygen species (ROS). RNS can be an alternative to nitrite in meat products; however, the active particles have a nonnegligible impact on meat components especially protein and fat. Excessive oxidation of meat products will cause quality deterioration. In this paper, the action modes of cold plasma technology on meat proteins and meat products are reviewed, as well as its regulatory effect and mechanism on the structure and function of myofibrillar protein and myoglobin in meat, and the current status of research on the application of cold plasma technology in meat preservation and processing is outlined. This systematic review is expected to provide a reference for the wide application of cold plasma technology in the meat industry.
