Servant Leadership and Teachers' Emotional Exhaustion-The Mediation Role of Hindrance Stress and Depersonalization.

This study aims to explore the impact of school servant leadership on teacher emotional exhaustion in the context of Chinese education, and analyze the mediating effects of teacher hindrance stress and depersonalization. Based on the Job Demand-Control-Support (JDCS) model and servant leadership theory, the research constructs a model for the influence mechanism of school servant leadership on teacher emotional exhaustion and validates it using Structural Equation Modeling (SEM). A total of 3751 primary and secondary school teachers from eight provinces in China participated in this study.

Three-dimensional super-resolution range-gated imaging based on Gaussian-range-intensity model.

Current range-gated imaging methods based on triangular or trapezoidal models face significant limitations in terms of the accuracy and precision of three-dimensional (3D) reconstruction. Here, we establish a range-gated 3D super-resolution image reconstruction method based on a Gaussian-range-intensity model. A denoised optimization method for image preprocessing is established to improve the distance accuracy of the reconstruction.

Active imaging through dense fog by utilizing the joint polarization defogging and denoising optimization based on range-gated detection.

Imaging through the scattering medium, such as fog, is important for military and civilian applications. However, the fog concentration restricts the current defogging methods; the image will be seriously degraded in dense fog scenes. Here, an imaging technique by developing joint active polarization defogging and denoising optimization methods based on range-gated detection is proposed for the target in fog conditions.

Degradation, isomerization and stabilization of three dicaffeoylquinic acids under ultrasonic treatment at different pH.

Dicaffeoylquinic acids (diCQAs) are found in a variety of edible and medicinal plants with various biological activities. An important issue is the low stability of diCQAs during extraction and food processing, resulting in the degradation and transformation. This work used 3,5-diCQA as a representative to study the influence of different parameters in ultrasonic treatment on the stability of diCQAs, including solvent, temperature, treatment time, ultrasonic power, duty cycle, and probe immersion depth.

Effect of steam explosion pretreatment on the composition and bioactive characteristic of phenolic compounds in Ramat cv. Hangbaiju powder with various sieve fractions.

Steam explosion (SE) pretreatment is an efficient technique to promote the fiber degradation and disrupt materials' cell wall. In this study, the effect of SE pretreatment on the changes in phenolic profile, and the in vitro digestion property of a Chinese indigenous herb "Hangbaiju" (HBJ) powder with various sieve fractions (150-, 180-, 250-, 425-, and 850-μm sieves) were studied. After SE pretreatment, the morphological structure, color attributes, and composition of phenolic compounds were altered significantly ( < .

The Relationship Between Workplace Incivility and Psychological Distress: The Moderating Role of Servant Leadership.

Background: The relationship between workplace incivility and psychological distress among nurses has been well-documented in the nursing literature. Management practices to reduce the negative impact are less clear. This study aimed to examine perceived servant leadership as a moderator between workplace incivility and psychological distress among nurses in Chinese hospitals.

Degradation kinetics and isomerization of 5--caffeoylquinic acid under ultrasound: Influence of epigallocatechin gallate and vitamin C.

5--Caffeoylquinic acid (5-CQA), also known as chlorogenic acid, exhibits various biological activities. Hence the interest in its property change during processing and extraction has increased. The present work studied the influence of ultrasound on the stability of 5-CQA at different pH (pH 4.

Ultrasonic degradation kinetics and isomerization of 3- and 4-O-caffeoylquinic acid at various pH: The protective effects of ascorbic acid and epigallocatechin gallate on their stability.

Caffeoylquinic acids are existed in many plant species with various biological and pharmacological activities. 3-O-caffeoylquinic acid and 4-O-caffeoylquinic acid are two isomers of caffeoylquinic acids, which may be degraded and transformed to their isomers in processing. The present paper found that the stability of 3- and 4-O-caffeoylquinic acid had decreased with the increasing solution alkalinity.

Ethical Leadership and Organizational Citizenship Behavior: Mediation of Trust and Psychological Well-Being.

Purpose: Nurses' behaviors are largely influenced by their managers' leadership style. The relationships between ethical leadership, trust, psychological well-being, and organizational citizenship behaviors have rarely been investigated in nursing studies. The current study attempted to examine the relationships between perceived ethical leadership, trust, psychological health, and nurses' organizational citizenship behaviors towards their patients in the context of Chinese hospitals.

How Incivility and Academic Stress Influence Psychological Health Among College Students: The Moderating Role of Gratitude.

Many students suffer from academic stress and uncivil behaviors at colleges and there is a need to identify to what extent these negative phenomena might impact students' mental health. The main purpose of this study is to examine the relationships between incivility, academic stress, and psychological health, as well as investigate the moderating role of gratitude. The study design of this research is cross-sectional.

Does ethical leadership boost nurses' patient-oriented organizational citizenship behaviours? A cross-sectional study.

Aims: To examine the relationships between perceived ethical leadership, perceived interactional justice climate, and patient-oriented organizational citizenship behaviour.

Design: A cross-sectional non-experimental design was employed.

Methods: The convenience sampling was adopted.

The Relationship between Challenge and Hindrance Stressors and Emotional Exhaustion: The Moderating Role of Perceived Servant Leadership.

Schoolteachers worldwide are facing stressful work conditions with heavy responsibilities. Stress may contribute to psychological disorders and physical health issues. The purposes of this study were (1) to investigate whether both challenge and hindrance stressors are positively associated with emotional exhaustion among Chinese schoolteachers and (2) to examine whether perceived servant leadership moderates the effects of challenge and hindrance stressors on emotional exhaustion.

Comparison of Phenolic Compounds and the Antioxidant Activities of Fifteen Ramat cv. 'Hangbaiju' in China.

This study investigated the phenolic compounds of 15 Ramat cv. 'Hangbaiju', including 6 'Duoju' and 9 'Taiju', using high performance liquid chromatography (HPLC). The antioxidant activities of these 'Hangbaiju' were estimated by DPPH, ABTS and FRAP assays.
