Pre-Separation Mother-Child Relationship and Adjustment Behaviors of Young Children Left Behind in Rural China: Pathways Through Distant Mothering and Current Mother-Child Relationship Quality.

In China, some rural parents do not live together with their children because they migrate to urban regions for work, and therefore they sometimes use a mobile phone in parenting their left-behind children (LBC), who are living with grandparents. This study used a serial mediation model to test the mediating roles of distant mothering and post-separation mother-child relationship quality in the link between recalled pre-separation mother-child relationship quality and social-emotional adjustment of 3-to-6-year-old LBC living in a rural context in China. Cross-sectional questionnaire data were collected from 185 triads, consisting of grandparents (rating child adjustment), migrant mothers (rating mother-child relationship qualities and distant mothering), and preschool teachers (rating child adjustment).

Psychometric properties of the Mobile Phone Parenting Practices Questionnaire (MPPPQ) for Chinese separated families with young children.

The current study aimed to examine the psychometric properties of the newly developed Mobile Phone Parenting Practices Questionnaire (MPPPQ) in a sample of Chinese migrant parents experiencing long-term parent-child separation. A total of 547 rural-to-urban migrant parents with 3-to-6-year-old children left in rural hometowns were recruited online and completed electronic questionnaires. Exploratory (N = 288) and confirmatory (N = 259) factor analyses were successively used to identify the factor structure.

Mixed valence copper oxide composites derived from metal-organic frameworks for efficient visible light fuel denitrification.

The construction of heterojunctions has been used to optimize photocatalyst fuel denitrification. In this work, HKUST-1(Cu) was used as a sacrificial template to synthesize a composite material CuO (CuO/CuO) that retains the original MOF framework for photocatalytic fuel denitrification by calcination at different temperatures. By adjusting the temperature, the content of CuO/CuO can be changed to control the performance and structure of CuO- effectively.

Cultural universality and specificity of teacher-student relationship: a qualitative study in Belgian, Chinese, and Italian primary school teachers.

Extensive evidence highlights the significant influence of dyadic, emotional teacher-student relationship (TSR) on students' cognitive functioning, socio-emotional development, and overall well-being. However, it remains unclear whether the TSR construct and its manifestations can be generalized across cultures. This qualitative study investigated TSR among 60 primary school teachers in Belgium, China, and Italy (i.

Effects of Spartina alterniflora Invasion on Soil Quality in Coastal Wetland of Beibu Gulf of South China.

Background: Since Spartina alterniflora (simplified as Spartina) has strong ecological competitiveness and rapid growth, it has been introduced and living in the coastal wetland regions of China for more than 30 years. Taking coastal wetland in the Beibu Gulf of south China as an example, the effects of Spartina invasion on soil quality were investigated to provide scientific basis for soil management.

Methodology: The soil quality of six different coastal wetlands, i.
