Burnout in kindergarten teachers is influenced by individual factors, social factors, and organizational factors. Kindergarten organizational climate as an external work resource may cause teacher burnout when it cannot meet their work demands. To explore the mechanisms that underlie the effects of kindergarten organizational climate on teacher burnout, we investigated the mediating effect of work-family conflict (i.e., work interfering with family and family interfering with work) on the relationship between kindergarten organizational climate and teacher burnout. The study sample included 436 kindergarten teachers in Henan, China. The Chinese versions of the Kindergarten Organizational Climate Scale, Kindergarten Teachers Work-Family Conflict Scale, and Kindergarten Teachers Burnout Scale were applied. The results showed that kindergarten organizational climate was positively correlated with work-family conflict and teacher burnout. Work-family conflict was positively correlated with teacher burnout. Work-family conflict partially mediated the effects of kindergarten organizational climate on teacher burnout. The mediating effect of family interfering with work was significantly stronger than the mediating effect of work interfering with family. The results are discussed with respect to the general literature on the correlation between organizational climate, WFC, and burnout.

Although the importance of psychological capital has been firmly supported by prior studies, the question of whether certain subgroups exist and how these various subgroups affect work engagement differentially remains under-explored. To gain an in-depth understanding of this problem, the present study conducted a person-centered method (latent profile analysis) to identify subgroups and then explore the relationship between psychological capital subgroups and work engagement. The study participants were kindergarten teachers in China (n = 2,790). The results showed that psychological capital was divided into three latent profiles: “rich type” (43.2% of the sample) “medium type” (46.3%), and “poor type” (10.5%). Compared to the other two types, the teachers with high psychological capital returned higher work engagement scores. Meanwhile, there was a significant difference among the three identified profiles regarding the location of the kindergarten, the type of kindergarten, and the teaching experience. The group owning more psychological capital tended to have more teaching experience, come from a developed area, and work in a public kindergarten. And after controlling the influence of the type of kindergarten, the location of kindergarten, and the teaching experience, the psychological capital of kindergarten teachers was still an important factor that affected teachers’ work engagement.

Background: During the long–time home quarantine due to COVID–19, preschool-age children can be easily stricken by negative emotions, which give rise to aggressive behaviors. Aggressive behaviors are of different types at the preschool stage. We aimed to investigate the differences of emotion regulation strategies among children age 3–6 yr old with different aggression types and explore the relationship between emotion regulation strategies and aggressive behaviors. Methods: The aggressive behaviors of 1,187 children sampled (event sampling method) from 5 kindergartens in five cities in Henan Province of China were observed on the spot in 2020. Three aggression types (i.e., physical, verbal, and indirect) were selected to conduct a questionnaire survey on emotion regulation strategies and discuss the differences among aggressive children in emotion regulation strategies. Results: Children of different genders are significantly different in aggressive behaviors and problem solving, as well as children at different age levels in self–comfort, passive reaction, and negative regulation strategies. Significant interaction exists between gender and aggression but not in negative regulation strategy; significant interaction also exists between age and aggression but not in cognitive reconstruction, substitutive activity, and aggressive behavior. Significant differences exist among children of different aggression types in positive and negative regulation strategies. The discrimination accuracy of emotion regulation strategies for aggression types is 66.5%. Conclusion: Significant differences exist among 3-6-yr-old aggressive children in emotion regulation strategies, and emotion regulation strategies can effectively distinguish aggressive children of different types.

Electrostatic discharge (ESD) events are causing an increasing amount of damage in advanced integrated circuits (ICs). Among the onchip ESD protection devices, the silicon controlled rectifier (SCR) is the most robust. We have proposed a new SCR with an embedded n-type metal-oxide-semiconductor field-effect transistor (nMOSFET). By properly adjusting the gate work function of the nMOSFET, the SCR obtains a low trigger voltage of 1.5 V and a low leakage current of 7.6 × 10 −10 A. The overshoot voltage under a fast ESD event is also reduced owing to the strong conduction of the nMOSFET. By numerical simulation, we evaluate the impact of the temperature, noise, and stress waveform on the ESD performance. The results are discussed and detailed physical insights are given.
