This study was based on ecological systems theory, combined with the concept of localization put forward by Chinese scholars, to explore the influence of the family (family cohesion) and personal (psychological suzhi) factors on middle school students' aggression. A total of 20,114 middle school students aged 12 to 18 years (M = 14.30, SD = 1.40) completed the Family Cohesion Questionnaire, the Psychological Suzhi Questionnaire, and the Chinese Version of Buss and Perry Aggression Questionnaire. The results indicated that there were significant negative correlations among family cohesion, psychological suzhi, and overall aggression along with its components. Additionally, psychological suzhi significantly mediated the relationship between family cohesion and aggression and its sub-dimensions. These results highlighted the important roles of family cohesion and psychological suzhi in adolescents' behavioral development and provided potential strategies to reduce middle school students' aggression., Author(s): Xu Wang [sup.1] [sup.2] , Yi-bo Geng [sup.1] [sup.2] , Jie Lin [sup.1] [sup.2] , Zhen-shuo Yi [sup.1] [sup.2] , Yan-ling Liu [sup.1] [sup.2] Author Affiliations: (1) grid.263906.8, 0000 [...]

Spatial inequality in migrant attainment has become a core issue in migrant welfare and urbanization. This paper investigates the spatial differences and related factors of migrant attainment in 337 Chinese cities using national survey data and applying the factor analysis method. The results indicate that migrants' challenges in the economic and residential dimensions contribute the most to the relatively low degree of migrant attainment. The spatial distribution of migrant attainment is reflected in higher grades clustered in blocks in separate provinces. The economic and residential dimensions have opposite outcomes and reveal differences between China's north and south. The cultural and psychological dimensions are homogeneous, and the civil rights dimension is zonal. The spatial pattern of migrant attainment is jointly shaped by both the characteristics of the receiving cities and the migrants themselves. Hindrance factors involving policy differentiation and spatial barriers have the greatest impact. This paper puts into practice the theory of human-space relationship, provides a deeper research connotation, and delves deeper into the role of migrants and receiving cities. These findings provide an path to increase migrant attainment and spatial equality: determine the spatial characteristics – clarify the dimensions of lower migrant attainment – address the key influencing factors.

The title compound, C15H14O3, has been obtained from the reaction of 2,4-dihydroxyacetophenone, potassium carbonate and benzyl bromide. The remaining hydroxy group is involved in an intramolecular O—H...O hydrogen bond. In the crystal, intermolecular C—H...O contacts occur.

Farmers in Liaoning, China, discovered two almost complete skeletons of Sinosauropteryx, a dinosaur species closely linked with Compsognathus. The skeletons are from the basal part of the Yixian Formation, which has four fossil-bearing sedimentary intercalations. The skeletons are particularly interesting for their integumentary structures, which are extremely well preserved. There are no structures showing the basic morphological features of modern bird feathers, but they could be protofeathers which have not previously been identified.

Twig blight is a serious disease of bayberry, which limits bayberry production. In order to prevent and manage the disease, we used high-throughput sequencing technology to analyze bacterial and fungal community richness and diversity in various organs of the tree, bulk and rhizosphere soil of healthy and diseased bayberry. The results showed significant differences in richness and diversity of bacteria and fungi in bulk soil, rhizosphere soil, roots, trunks, barks, and leaves between twig blight diseased trees and healthy trees. In bulk soil, the richness and diversity of bacteria significantly decreased, while that of fungi significantly increased. In barks of diseased trees, the richness and diversity of bacteria significantly increased, and those of fungi significantly decreased. The relative abundance of dominant bacteria and fungi in various organs, bulk soil, and root surface soil changed significantly at phylum, class, and genus levels in the diseased trees. The relative abundance of Pseudomonas sp. on the trunks, roots, and root surface soils of diseased trees significantly decreased, and Fusarium sp. of the diseased root surface and bulk soils also significantly decreased, while the relative abundance of Penicillium sp. on the diseased root surface and bulk soils significantly increased. Pestalotiopsis sp., from the same genus as the twig blight pathogen, was less abundant in the roots but more abundant in the leaves, trunks, barks as well as root surface soils and bulk soils of the diseased bayberry trees than those of the health trees. The relative abundance of Pestalotiopsis sp. was positively correlated with those of most of the fungi. Our results might provide useful theoretical basis for the development of ecological improvement and healthy-tree cultivation technology, and biological control of bayberry twig blight disease.

LIN28A, an RNA-binding protein, plays an important role in porcine induced pluripotent stem cells (piPSCs). However, the molecular mechanism underlying the function of LIN28A in the maintenance of pluripotency in piPSCs remains unclear. Here, we explored the function of LIN28A in piPSCs based on its overexpression and knockdown. We performed total RNA sequencing (RNA-seq) of piPSCs and detected the expression levels of relevant genes by quantitative real-time polymerase chain reaction (qRT-PCR), western blot analysis, and immunofluorescence staining. Results indicated that piPSC proliferation ability decreased following LIN28A knockdown. Furthermore, when LIN28A expression in the sh LIN28A2 group was lower (by 20%) than that in the negative control knockdown group ( sh NC), the pluripotency of piPSCs disappeared and they differentiated into neuroectoderm cells. Results also showed that LIN28A overexpression inhibited the expression of DUSP (dual-specificity phosphatases) family phosphatases and activated the mitogen-activated protein kinase (MAPK) signaling pathway. Thus, LIN28A appears to activate the MAPK signaling pathway to maintain the pluripotency and proliferation ability of piPSCs. Our study provides a new resource for exploring the functions of LIN28A in piPSCs.

The title compound, C(15)H(14)O(3), has been obtained from the reaction of 2,4-dihy-droxy-acetophenone, potassium carbonate and benzyl bromide. The remaining hy-droxy group is involved in an intra-molecular O-H⋯O hydrogen bond. In the crystal, inter-molecular C-H⋯O contacts occur.
