Published: July 2024

The ecosystems across the world are affected by diverse impacts of climate change. Climate change will also affect soil seed bank as the seed bank is determined by the plants that are above the ground. This study was conducted to determine whether rainfall interception and resting period will affect the soil seed bank or not. Rainfall interception was employed as main plot treatment at four different levels—namely, 15%, 30%, 60%, and 0%—and the main plot treatments were each replicated five times using the rainout shelters arranged as main plot treatments in a split-plot experimental design. The main plots are 49 m2 (7 m × 7 m) in size and were covered by metal frame structures with V-shaped clear acrylic bands on top without ultraviolet filter, and these plots were sub-divided into two sub-plots to determine the effect of resting periods (70 and 90 days). The soil samples were 8 cm in diameter and 20 cm in depth (1,005 cm3). We used seed emergence method rather than seed separation method to determine the soil seed bank due to the very small size of some seeds for some species. The 60% rainfall interception resulted in significantly high forb densities at both resting periods. The forb densities decreased by 32 and 35% at 15% and 30%, while they increased by 195% at 60% rainfall interception compared to 0% rainfall interception at 70-day resting period. Resting period significantly affected grass densities at 60% rainfall as the densities were higher at 70- than 90-day resting period. At 90-day resting period, grass densities were significantly higher at 0% rainfall interception than the rest of the treatments, while the grass densities were significantly lower at 60% rainfall interception. The 60% rainfall interception resulted in significantly (p&lt; 0.05) higher total densities (forbs and grass) in both resting periods. Total density increased by 2.9% and 143.48% at 15% and 60% rainfall interception, respectively. Our results show that drought has a negative effect on grass soil seed bank, while it improves the forbs soil seed bank. Furthermore, the resting period has no significant effects on soil seed bank in grasslands.
The effects of teacher nodding: exploring mimicry, engagement, and wellbeing in the EFL classroom

Published: July 2024

IntroductionThis article explores teacher and student mimicry of one another’s nodding in the classroom and whether it impacts teacher wellbeing. Studies have consistently demonstrated correlations between physical mimicry and various desirable outcomes, including empathy, rapport, affiliation, and personal liking. While students experiencing such emotional connections with their teachers tend to achieve more academically, teachers also benefit, showing, for example, reduced stress levels. Research exploring the link between mimicry of nonverbal communication such as nodding and teacher wellbeing is limited, however. This paper reports on a very small data set to explore the analysis of synchrony between teacher and learner in the English as a Foreign Language classroom.MethodsQuantitative and qualitative methodologies were combined to gather both objective and subjective data. A Granger causality analysis was undertaken to understand both immediate and delayed mimicry of nodding, and cross-correlograms produced. Teacher stress levels were measured using the ratio of the low-frequency (LF) and high-frequency (HF) heartrate power bands, which was then validated with a two-dimensional model. Next, the teacher was interviewed about her wellbeing and pedagogy while watching the video data. The results were then combined and analyzed.Results and discussionWhile much immediate mimicry during active teaching sessions was evident in the video data, it was not found to be at a statistically significant level. The Granger Causality analysis showed, however, that students consistently mimicked changes in teacher nodding rate in the following dyad activity. Cross-correlation analysis between teacher and student participants during active teaching sessions and also within student dyads during pairwork activities showed strong relationships at lags spanning 0–60 s. No statistical significance between student and/or teacher nodding and either teacher self-assessed wellbeing or physiological stress levels was found, however. This is explained first by the teacher evaluating her normal baseline state as neutral rather than positive (as was reflected by the LF/HF), and second by her physiological responses to the emotional regulation strategies of surface and deep acting. Qualitative observational data, however, indicated that teacher nodding positively influenced student comprehension, interest, and confidence, and the teacher’s own professional wellbeing.

BackgroundDiabetic retinopathy (DR) is considered one of the most severe complications of diabetes mellitus, but its pathogenesis is still unclear. We hypothesize that certain genes exert a pivotal influence on the progression of DR. This study explored biomarkers for the diagnosis and treatment of DR through bioinformatics analysis.MethodsWithin the GSE221521 and GSE189005 datasets, candidate genes were acquired from intersections of genes obtained using WGCNA and DESeq2 packages. Mendelian randomization (MR) analysis selected candidate biomarkers exhibiting causal relationships with DR. Receiver Operating Characteristic (ROC) analysis determined the diagnostic efficacy of biomarkers, the expression levels of biomarkers were verified in the GSE221521 and GSE189005 datasets, and a nomogram for diagnosing DR was constructed. Enrichment analysis delineated the roles and pathways associated with the biomarkers. Immune infiltration analysis analyzed the differences in immune cells between DR and control groups. The miRNet and networkanalyst databases were then used to predict the transcription factors (TFs) and miRNAs, respectively, of biomarkers. Finally, RT-qPCR was used to verify the expression of the biomarkers in vitro.ResultsMR analysis identified 13 candidate biomarkers that had causal relationships with DR. The ROC curve demonstrated favorable diagnostic performance of three biomarkers (OSER1, HIPK2, and DDRGK1) for DR, and their expression trends were consistent across GSE221521 and GSE189005 datasets. The calibration curves and ROC curves indicated good predictive performance of the nomogram. The biomarkers were enriched in pathways of immune, cancer, amino acid metabolism, and oxidative phosphorylation. Ten immune cell lines showed notable disparities between the DR and control groups. Among them, effector memory CD8+ T cells, plasmacytoid dendritic cells, and activated CD4+ T cells exhibited good correlation with biomarker expression. The TF-mRNA-miRNA network suggested that hsa-mir-92a-3p, GATA2, and RELA play important roles in biomarker targeting for DR. RT-qPCR results also demonstrated a notably high expression of HIPK2 in patients with DR, whereas notably low expression of OSER1.ConclusionOSER1, HIPK2, and DDRGK1 were identified as biomarkers for DR. The study findings provide novel insights into the pathogenesis of DR.
