Examining the Antecedents of Novice STEM Teachers’ Job Satisfaction: The Roles of Personality Traits, Perceived Social Support, and Work Engagement

It is reported that teachers’ satisfaction levels are lower and stress levels are higher than other professional groups in many countries. This is especially true for science, technology, engineering, and mathematics (STEM) teachers. Considering job satisfaction has a direct impact on turnover intention, low satisfaction levels have led to high turnover rates and thus exacerbated the shortages of STEM teachers. Hence, there is an urgent need to explore the antecedents of novice STEM teachers’ job satisfaction. This study proposes a new model to show how novice STEM teachers’ personality traits and perceived social support influence their job satisfaction. A total of 2592 novice STEM teachers in eighteen randomly selected high schools in China were recruited. Data were analyzed using the structural equation modeling approach. The results illustrated that most novice STEM teachers had low levels of job satisfaction. Novice STEM teachers’ personality traits could directly and indirectly impact their job satisfaction. Meanwhile, novice STEM teachers’ job satisfaction was also directly influenced by work engagement and indirectly influenced by their perceived social support. Our findings theoretically contribute to the understanding of the determinants of STEM teachers’ job satisfaction and have important practical implications.
Endurance exercise preserves physical function in adult and older male C57BL/6 mice: high intensity interval training (HIIT) versus voluntary wheel running (VWR)

Exercise has been shown to improve physical function, mitigate aspects of chronic disease and to potentially alter the trajectory of age-related onset of frailty and sarcopenia. Reliable and valid preclinical models are necessary to elucidate the underlying mechanisms at the intersection of age, exercise, and functional decline. The purpose of this study was to compare, head to head, the effects of two common pre-clinical models of endurance exercise: high intensity interval training (HIIT) and voluntary wheel running (VWR). The hypothesis was that a prescribed and regimented exercise program, HIIT, would prove to be a superior training method to unregulated voluntary exercise, VWR. To investigate this hypothesis, we evaluated adult (n = 24, designated 10 m, aged 6 months at the beginning of the study, 10 months at its completion) and older adult (n = 18, designated 26 m, aging from 22 months to 26 months over the course of the study) C57BL/6 male mice. These mice were randomly assigned (with selection criteria) to a 13-week program of voluntary wheel running (VWR), high intensity interval training (HIIT), or sedentary control (SED). The functional aptitude of each mouse was determined pre- and post-training using our composite CFAB (comprehensive functional assessment battery) scoring system consisting of voluntary wheel running (volitional exercise and activity rate), treadmill (endurance), rotarod (overall motor function), grip meter (forelimb strength), and inverted cling (whole body strength/endurance). To measure sarcopenia, we tracked body mass, body composition (with EchoMRI), plantar flexor torque (in 10 m), and measured muscle wet mass post-training. Overall, adult CFAB scores decreased while body mass and percent body fat increased as they matured; however, exercise significantly mitigated the changes (p < 0.05) compared to SED. Older adults demonstrated preservation of function (CFAB) and reduced body fat (p < 0.05) compared to SED. To conclude, both types of exercise maintained physical function equally in older mice.
Assessing the threat of future megadrought in Iberia

Water scarcity is a critical issue in Iberia but few studies have investigated future drought over the region. The few that do are continental or global studies and do not report the range of possible future projections. In this paper, historical drought and future projections of drought were examined, using observed and downscaled rainfall data from climate models, for the main Iberian international basins (Douro, Tagus and Guadiana). Two drought indices were used, the standardized precipitation index (SPI) and the drought severity index (DSI). However, problems were found in the distribution fitting required for the calculation of SPI which render this index inadequate for assessing droughts in Iberia. The skill of CMIP5 climate models in representing historical drought for the Douro, Tagus and Guadiana is very variable with some not showing enough persistence of dry conditions, and others simulating droughts that are too long and too severe. Nevertheless, the observed range of drought conditions for these basins was encompassed by the ensemble members. Furthermore, we found no relationship between performance in simulating mean large‐scale circulation and model ability to reproduce the historical drought characteristics for the region. All models project an intensification of drought conditions for the three basins. However, some only project small increases, while most project extreme multi‐year droughts by the end of the century. We found that climate model future projections are neither related to their performance in simulating historical drought nor to their large‐scale circulation patterns. This result emphasises the need for climate change impact studies to take into account the whole range of climate model projections in order to provide the best information for robust adaptation. Choosing one or a subset of climate models based on historical performance would not lead to a credible and justified reduction in uncertainty.
Review and Analysis of RGBT Single Object Tracking Methods: A Fusion Perspective

Visual tracking is a fundamental task in computer vision with significant practical applications in various domains, including surveillance, security, robotics, and human-computer interaction. However, it may face limitations in visible light data, such as low-light environments, occlusion, and camouflage, which can significantly reduce its accuracy. To cope with these challenges, researchers have explored the potential of combining the visible and infrared modalities to improve tracking performance. By leveraging the complementary strengths of visible and infrared data, RGB-infrared fusion tracking has emerged as a promising approach to address these limitations and improve tracking accuracy in challenging scenarios. In this paper, we present a review on RGB-infrared fusion tracking. Specifically, we categorize existing RGBT tracking methods into four categories based on their underlying architectures, feature representations, and fusion strategies, namely feature decoupling based method, feature selecting based method, collaborative graph tracking method, and traditional fusion method. Furthermore, we provide a critical analysis of their strengths, limitations, representative methods, and future research directions. To further demonstrate the advantages and disadvantages of these methods, we present a review of publicly available RGBT tracking datasets and analyze the main results on public datasets. Moreover,we discuss some limitations in RGBT tracking at present and provide some opportunities and future directions for RGBT visual tracking, such as dataset diversity, unsupervised and weakly supervised applications. In conclusion, our survey aims to serve as a useful resource for researchers and practitioners interested in the emerging field of RGBT tracking, and to promote further progress and innovation in this area.
Enhancing Critical Digital Literacy of Preservice Preschool Teachers through Service Learning: The Moderator of Online Social Capital

This research delves into the examination of the correlation between service learning and critical digital literacy among preservice preschool teachers in Taiwan, with a particular emphasis on the role of online social capital. The survey took place in Taiwan with preservice preschool teachers who willingly completed a questionnaire. Initially, there were 416 data samples for further statistical analysis. This study utilizes literature reviews and theoretical reflections to examine the observed variables and factors in the “Service Learning and Critical Digital Literacy Scales” (SLCDL) questionnaire. To assess these aspects, a Chinese questionnaire is used, covering “service learning”, “critical digital literacy”, and “online social capital”. Using partial least squares analysis, researchers investigate the intricate interplay of online social capital in shaping the nexus between service learning experiences and the advance of critical digital literacy competencies. These results showed that service learning increased critical digital literacy among preservice preschool teachers, and online social capital played a mediating role in this relationship between service learning and critical digital literacy. We should actively encourage preservice preschool teachers to increase their critical awareness by understanding vulnerability and experiencing reality from the perspective of community partners. In addition, we need to provide more service learning opportunities that incorporate online social capital to enhance their critical digital literacy.
The Work of Southering: "Southern Justice" and the Moral Landscape of Uneven Racism

This article seeks to stimulate a discussion about the ways in which scholars may reproduce the identity discourse of internal orientalism (here called "southering") and the moral landscape of uneven racism in the process of critiquing injustice in the southeastern states. It points to the problems with making explicit and unsubstantiated comparisons on issues such as racism between the "South" and "North" and highlights discursive forms that risk triggering reader interpretations (such as the idea of "Southern distinctiveness") that may be inconsistent with the intentions of the author. It ends by considering a few strategies for minimizing the communication of unintended messages, including more precision with regard to temporal and spatial boundaries, using a form of the "contrapuntal method" where generalizations about "the South" are accompanied by statements describing the status of the problem in question in the rest of the country, employing a materialist definition of racism as well as a dialectical analysis that focuses on process and relation.Resumen:Este artículo pretende estimular una discusión sobre la manera en que los académicos pueden reproducir el discurso de identidad del orientalismo interno (aquí se refiere al sureño) y el paisaje moral del racismo desigual en el proceso de crítica de la injusticia en los estados del sureste. Señala los problemas de hacer comparaciones explícitas y sin fundamento en temas como el racismo entre el "Sur" y el "Norte" y destaca las formas discursivas que arriesgan el desencadenamiento de interpretaciones de lectores (como la idea de "carácter distintivo del Sur") que puede ser incompatible con Las intenciones del autor. El estudio termina considerando algunas estrategias para minimizar la comunicación de mensajes no deseados, incluyendo una mayor precisión con respecto a los límites temporales y espaciales, usando una forma del "método contrapunto" donde las generalizaciones sobre "el Sur" van acompañadas de declaraciones que describen el estado del problema en cuestión en el resto del país, empleando una definición materialista del racismo, así como un análisis dialéctico que se centra en el proceso y la relación.

Petrogenesis of two stages of Cretaceous granites in south‐west Fujian Province: Implications for the tectonic transition of South‐east China

Zircon U–Pb data indicate that Cretaceous magmatism in Fujian Province occurred in two pulses, with the Xiyang, Yangshan, Wuci, Dehua, Juzhou, and Xiandu plutons emplaced between 147 ± 1 and 126 ± 1 Ma and the Hutou and Guangqiao plutons emplaced at 109 ± 1 Ma. Combining these previously published ages with the new data obtained during this study indicates that the magmatism in the study area occurred in two distinct stages at 145–125 and 110–100 Ma, both have I‐type characteristics. The earlier I‐type granites are characterized by relatively high concentrations of SiO2 (mean = 75.73 wt.%) and low concentrations of MgO (mean of 0.21 wt.%) and are metaluminous to weakly peraluminous (mean A/CNK = 1.03). They contain relatively high total rare‐earth element (ΣREE) concentrations (mean of 139.3 ppm) with well‐developed Eu anomalies and are relatively enriched in the large‐ion lithophile elements (LILE) and the light REE (LREE) but depleted in Ba, Sr, P, Ti, Nb, and Ta. In contrast, the younger I‐type granites contain lower concentrations of SiO2 (mean of 67.63 wt.%), higher concentrations of MgO (mean of 1.47 wt.%), and are metaluminous to weakly peraluminous (mean A/CNK = 0.96). They also have moderate REE values (mean of 150.26 ppm) without significant Eu anomalies and are relatively enriched in LREE, Rb, Th, U, K, Sr, and Pb and depleted in Nb, Ta, P, Ti, Y, and Yb. The two‐stage Nd model ages (T2DM) of Cretaceous granites are 1.46 to 1.88 Ga (mean of 1.57 Ga) and 1.16–1.60 Ga (mean of 1.36 Ga), respectively. The two‐stage Hf model ages (T2DM) of Cretaceous granites are 1.19–1.82 Ga (mean of 1.54 Ga) and 0.46–1.20 Ga (mean of 0.91 Ga), respectively. It is likely that the earlier I‐type granites were derived from magmas generated by the partial melting of Mesoproterozoic metabasaltic material, whereas the later I‐type granites were derived from magmas generated by partial melting of a mixed lithology containing Mesoproterozoic to Neoproterozoic metabasaltic to metatonalitic rocks that were underplated by medium‐ to high‐K basaltic magmas. A geological comparison between south‐western Fujian Province and adjacent areas indicates that the earlier I‐type granites were emplaced in a compressional environment associated with the subduction of the paleo‐Pacific Plate at 145–125 Ma. In contrast, the later I‐type plutons are associated with intraplate extension accompanied by the post‐subduction slab roll‐back of the paleo‐Pacific Plate. The two magmatic stages represent a transition from compressional to intraplate extensional tectonics between 125 and 110 Ma, with mantle‐derived material playing a crucial role in the formation of the I‐type granites.
Structures, Mechanisms, and Physiological Functions of Zinc Transporters in Different Biological Kingdoms

Zinc transporters take up/release zinc ions (Zn2+) across biological membranes and maintain intracellular and intra-organellar Zn2+ homeostasis. Since this process requires a series of conformational changes in the transporters, detailed information about the structures of different reaction intermediates is required for a comprehensive understanding of their Zn2+ transport mechanisms. Recently, various Zn2+ transport systems have been identified in bacteria, yeasts, plants, and humans. Based on structural analyses of human ZnT7, human ZnT8, and bacterial YiiP, we propose updated models explaining their mechanisms of action to ensure efficient Zn2+ transport. We place particular focus on the mechanistic roles of the histidine-rich loop shared by several zinc transporters, which facilitates Zn2+ recruitment to the transmembrane Zn2+-binding site. This review provides an extensive overview of the structures, mechanisms, and physiological functions of zinc transporters in different biological kingdoms.

In conclusion, this research underscores the pivotal role of demand forecasting as a crucial tool for businesses, particularly in similar industries, to enhance inventory management and curtail lost sales. The practical recommendations contribute significantly to inventory management, offering actionable insights for businesses seeking to optimize their inventory processes.
pNIPAm-Based pH and Thermoresponsive Copolymer Hydrogel for Hydrophobic and Hydrophilic Drug Delivery

The regulated and targeted administration of hydrophobic and hydrophilic drugs is both promising and challenging in the field of drug delivery. Developing a hydrogel which is responsive to dual stimuli is considered a promising and exciting research area of study. In this work, melamine functionalized poly-N-isopropyl acrylamide-co-glycidyl methacrylate copolymer has been developed by copolymerizing glycidyl methacrylate (GMA) monomer with N-isopropyl acrylamide (NIPAm) and further functionalized with melamine units (pNIPAm-co-pGMA-Mela). The prepared pNIPAm-co-pGMA-Mela copolymer hydrogel was characterized using various characterization techniques, including 1H NMR, FTIR, SEM, zeta potential, and particle size analysis. A hydrophobic drug (ibuprofen, Ibu) and hydrophilic drug (5-fluorouracil, 5-Fu) were selected as model drugs. Dual pH and temperature stimuli-responsive drug release behavior of the pNIPAm-co-pGMA-Mela hydrogel was evaluated under different pH (pH 7.4 and 4.0) and temperature (25 °C, 37 °C, and 45 °C) conditions. Furthermore, the in vitro biocompatibility of the developed pNIPAm-co-pGMA-Mela copolymer hydrogel was determined on MDA-MB-231 cells. The pH and temperature-responsive drug delivery study results reveal that the pNIPAm-co-pGMA-Mela hydrogel system is responsive to both pH and temperature stimuli and exhibits about ~100% of Ibu and 5-Fu, respectively, released at pH 4.0/45 °C. Moreover, the MTT assay and hemocompatibility analysis results proved that the pNIPAm-co-pGMA-Mela hydrogel system is biocompatible and hemocompatible, suggesting that that it could be used for drug delivery applications. The experimental results suggest that the proposed pNIPAm-co-pGMA-Mela hydrogel system is responsive to dual pH and temperature stimuli, and could be a promising drug carrier system for both hydrophilic and hydrophobic drug delivery applications.
Distribuição espacial em microescala da palmeira carnaúba, Copernicia prunifera (Mill) H. E. Moore

A palmeira carnauba ocorre em monodominância nas populacoes naturais das planicies inundaveis do semiarido nordestino. Entretanto, sao ausentes os estudos que caracterizam o padrao espacial em microescala dentro das populacoes. Assim, o estudo foi realizado com o objetivo de caracterizar a distribuicao espacial da Copernicia prunifera em regiao semiarida do Rio Grande do Norte. O levantamento foi realizado em uma area rural do municipio de Lagoa de Pedras, RN. Foram amostrados todos os individuos adultos reprodutivos em uma area de 1,1 hectares, totalizando 33 plantas. Utilizou-se como parâmetro de definicao dos adultos a presenca de eventos reprodutivos (flores ou frutos). O registro das posicoes geograficas (x e y) de todos os individuos amostrados na populacao ( N = 33) foi realizado com o auxilio de um aparelho de GPS. Foi utilizada a funcao de segunda ordem da densidade de vizinhos (NDF - Neighbourhood Density Function ) em intervalos de classes de distância (t) entre 2 e 20 m. As analises foram realizadas por meio do programa SpPack 1.38. O padrao espacial obtido pela analise univariada, onde foi calculada a densidade de todos os individuos, mostrou no correlograma um padrao de “ J invertido”, indicando significantes niveis de agregacao ate o raio de 10 m do individuo focal. Observou-se que a partir de distâncias superiores a 10 metros, os individuos apresentaram uma distribuicao aleatoria. Assim, conclui-se a dispersao restrita ao redor do parental pode ser a principal causa de determinacao do padrao espacial agregado em microescala da C. prunifera .
