Teacher Job Satisfaction in Public Schools: The Relation to the Years of Teaching Experience

This study examined the overall teacher job satisfaction in public schools and whether there was a relationship between years of teaching experience and teacher job satisfaction in public schools. Thirty-six teachers from western New York State were surveyed using Spector’s Job Satisfaction Survey. The result showed that there was a moderate negative relationship between teacher job satisfaction of operating procedures and years of teaching experience, which means with the increase of the years of teaching experience, teachers in public schools were more dissatisfied about their heavy workload. However, there was no strong relationship between overall teacher job satisfaction and years of teaching experience

Representing transition experiences: A multimodal critical discourse analysis of young immigrants in children’s literature

Because literature can serve as a mirror for children’s self-reflection and a window into humanizing insights on immigrants and immigration, it can be a powerful educational tool to promote understanding of immigrant learner’s experiences and needs. However, this has not always been the case. As such, informed by our theoretical framework of critical discourse studies (CDS) and raciolinguistics, this study explores the representations of immigrant children’s experiences in children’s literature. Employing multimodal critical discourse analysis, the authors analyze the visual and verbal representations of immigrant children (and the ideologies behind them) in 18 picture books with immigration themes. Findings reveal how the children are represented visually and/or verbally in ways that create understanding and empathy for the characters, but other times in more problematic ways. The authors conclude with suggestions for how to select (visual and verbal) curricula that avoids problematic ideologies of immigrant children and how to teach children to de-construct these ideologies when they encounter them

Psychological Barriers in the Process of Professional Development among College Teachers

This paper analyzes the physical and mental state of college teachers in the process of career development, in order to find out the psychological barriers in the process of career development of college teachers, and puts forward targeted management strategies. That can protect the mental health of Chinese college teachers in their career development

“It was just my name!”: A CRT/CRF Analysis of International Female Graduate Students’ Perceptions and Experiences Regarding Their Ethnic Name

Although international female students accounted for 44% of the enrolled international students in the United States (U.S. Department of Homeland Security’s Student and Exchange Visitor Information System, 2020), their experiences regarding their ethnic name are relatively understudied in the onomastic literature. This study considers the experiences of eight international female graduate students of Color who are studying at a Midwestern predominantly White university. Utilizing critical race theory (CRT) and critical race feminism (CRF) as the theoretical and analytical lenses, this qualitative phenomenological study collected data through semistructured, in-depth interviews. We explore the meaning of ethnic names and their connection to participants’ multidimensional identities. The findings include experiences with microaggressions, discrimination, and racism among students in relation to their ethnic name and point to underlying factors. Finally, implications are offered for students, faculty members, and administrators to build authentically inclusive and equitable learning communities more effectively

Glycogen synthase kinase-3β inhibition induces nuclear factor-κB-mediated apoptosis in pediatric acute lymphocyte leukemia cells

<p>Abstract</p> <p>Background</p> <p>Molecular therapies that target genetic abnormalities in leukemic cells and their affected signaling pathways have been emerging in pediatric acute lymphoblastic leukemia (ALL). Glycogen synthase kinase-3β (GSK-3β) has recently been found to positively regulate the activity of nuclear factor-κB (NF-κB). Here, we investigated the relationship between GSK-3β inhibition and NF-κB in apoptosis of pediatric primary leukemia cells obtained from 39 newly diagnosed ALL children in China.</p> <p>Methods</p> <p>Bone marrow mononuclear cells (BMMC) were isolated by density gradient centrifugation from the heparinized aspirates of children with ALL. We used immunofluorescence staining to detect nuclear GSK-3β in these cells. After treatment with chemically distinct GSK-3β inhibitors in vitro, NF-κB transcriptional activity was identified by means of western blotting and electrophoretic mobility shift assay (EMSA). NF-κB-mediated apoptosis was detected by Annexin V-PE/7-AAD double-staining flow cytometry. The expression level of the <it>survivin </it>gene was detected by reverse-transcriptase polymerase chain reaction (RT-PCR).</p> <p>Results</p> <p>GSK-3β significantly accumulates in the nuclei of ALL cells than in the nuclei of control cells. Cell death induced by GSK-3β inhibition in ALL cells was mediated by a downregulation of NF-κB p65 transcriptional activity. GSK-3β inhibition significantly decreased the expression of the NF-κB target gene <it>survivin</it>.</p> <p>Conclusions</p> <p>These results indicate that inhibition of GSK-3β downregulates the NF-κB activation pathway, leading to suppression of the expression of an NF-κB-regulated gene and promotion of apoptosis in ALL cells in vitro. Furthermore, our findings suggest that GSK-3β or NF-κB is a potential therapeutic target in the treatment of pediatric ALL.</p

SigFormer: Sparse Signal-Guided Transformer for Multi-Modal Human Action Segmentation

Multi-modal human action segmentation is a critical and challenging task with a wide range of applications. Nowadays, the majority of approaches concentrate on the fusion of dense signals (i.e., RGB, optical flow, and depth maps). However, the potential contributions of sparse IoT sensor signals, which can be crucial for achieving accurate recognition, have not been fully explored. To make up for this, we introduce a Sparse signalguided Transformer (SigFormer) to combine both dense and sparse signals. We employ mask attention to fuse localized features by constraining cross-attention within the regions where sparse signals are valid. However, since sparse signals are discrete, they lack sufficient information about the temporal action boundaries. Therefore, in SigFormer, we propose to emphasize the boundary information at two stages to alleviate this problem. In the first feature extraction stage, we introduce an intermediate bottleneck module to jointly learn both category and boundary features of each dense modality through the inner loss functions. After the fusion of dense modalities and sparse signals, we then devise a two-branch architecture that explicitly models the interrelationship between action category and temporal boundary. Experimental results demonstrate that SigFormer outperforms the state-of-the-art approaches on a multi-modal action segmentation dataset from real industrial environments, reaching an outstanding F1 score of 0.958. The codes and pre-trained models have been available at https://github.com/LIUQI-creat/SigFormer

Tracking the nematicity in cuprate superconductors: a resistivity study under uniaxial pressure

Overshadowing the superconducting dome in hole-doped cuprates, the pseudogap state is still one of the mysteries that no consensus can be achieved. It has been suggested that the rotational symmetry is broken in this state and may result in a nematic phase transition, whose temperature seems to coincide with the onset temperature of the pseudogap state $T^*$ around optimal doping level, raising the question whether the pseudogap results from the establishment of the nematic order. Here we report results of resistivity measurements under uniaxial pressure on several hole-doped cuprates, where the normalized slope of the elastoresistivity $\zeta$ can be obtained as illustrated in iron-based superconductors. The temperature dependence of $\zeta$ along particular lattice axis exhibits kink feature at $T_{k}$ and shows Curie-Weiss-like behavior above it, which may suggest a spontaneous nematic transition. While $T_{k}$ seems to be the same as $T^*$ around the optimal doping and in the overdoped region, they become very different in underdoped La$_{2-x}$Sr$_{x}$CuO$_4$. Our results suggest that the nematic order, if indeed existing, is an electronic phase within the pseudogap state.Comment: 6 pages, 4 figure
