Impact of Social Support on Female Teachers Work Engagement and Organizational Commitment at Secondary School Level

This current research study was planned to study the impact of social support on female teachers' work engagement and organizational commitment at the secondary school level in Khyber-Pakhtunkhwa. This research study was conducted in three districts of the Malakand region of Khyber Pakhtunkhwa, Pakistan. All female teachers in public sector schools and private sector schools were taken as the population of the study. However, 1354 teachers were selected as the sample size.Standardized research instruments were used for data collection. A total of five alternative hypotheses were formulated. The correlation coefficient, regression analysis, means score comparison and t-test were used. The entire five hypotheses were accepted. A significant relationship was found between social support and female teachers' work engagement and organizational commitment. A significant difference was found between public school female teachers and private school female teachers regarding social support. It is recommended that proper family and institutional support may be provided to female teachers to work diligently. In future, researchers may extend this research work by taking some other work-related variables like psychological capital and emotional intelligence as moderators/mediators.
Regulatory Network of Serine/Arginine-Rich (SR) Proteins: The Molecular Mechanism and Physiological Function in Plants

Serine/arginine-rich (SR) proteins are a type of splicing factor. They play significant roles in constitutive and alternative pre-mRNA splicing, and are involved in post-splicing activities, such as mRNA nuclear export, nonsense-mediated mRNA decay, mRNA translation, and miRNA biogenesis. In plants, SR proteins function under a complex regulatory network by protein–protein and RNA–protein interactions between SR proteins, other splicing factors, other proteins, or even RNAs. The regulatory networks of SR proteins are complex—they are regulated by the SR proteins themselves, they are phosphorylated and dephosphorylated through interactions with kinase, and they participate in signal transduction pathways, whereby signaling cascades can link the splicing machinery to the exterior environment. In a complex network, SR proteins are involved in plant growth and development, signal transduction, responses to abiotic and biotic stresses, and metabolism. Here, I review the current status of research on plant SR proteins, construct a model of SR proteins function, and ask many questions about SR proteins in plants.
IRF4 as an Oncogenic Master Transcription Factor

Simple Summary Master transcription factors regulate essential developmental processes and cellular maintenance that characterize cell identity. Many of them also serve as oncogenes when aberrantly expressed or activated. IRF4 is one of prime examples of oncogenic master transcription factors that has been implicated in various mature lymphoid neoplasms. IRF4 forms unique regulatory circuits and induces oncogenic transcription programs through the interactions with upstream pathways and binding partners. Abstract IRF4 is a transcription factor in the interferon regulatory factor (IRF) family. Since the discovery of this gene, various research fields including immunology and oncology have highlighted the unique characteristics and the importance of IRF4 in several biological processes that distinguish it from other IRF family members. In normal lymphocyte development and immunity, IRF4 mediates critical immune responses via interactions with upstream signaling pathways, such as the T-cell receptor and B-cell receptor pathways, as well as their binding partners, which are uniquely expressed in each cell type. On the other hand, IRF4 acts as an oncogene in various mature lymphoid neoplasms when abnormally expressed. IRF4 induces several oncogenes, such as MYC, as well as genes that characterize each cell type by utilizing its ability as a master regulator of immunity. IRF4 and its upstream factor NF-κB form a transcriptional regulatory circuit, including feedback and feedforward loops, to maintain the oncogenic transcriptional program in malignant lymphoid cells. In this review article, we provide an overview of the molecular functions of IRF4 in mature lymphoid neoplasms and highlight its upstream and downstream pathways, as well as the regulatory circuits mediated by IRF4.
Managing managers: the evolving management story in context

The way organisations manage their managers is undergoing significant change. Despite this, it is a topic that has faced limited scholarly consideration. For decades, there was an evergrowing mountain of research on management that has moved our understanding forward, but much less attention has been paid to managers and less still to how they are themselves managed within organisations. This book attempts to fill this gap; it reviews the research conducted to date; and explores future research pathways. Our contribution is structured into 18 chapters; at the heart of each chapter is the notion that the world of managers has changed substantially since the ‘organization man’ of the 1950s. We have witnessed much excitement in the discussion about the future of management, with both pessimistic and optimistic views being put forward. Our attention was caught when, in the wake of delayering, downsizing, reengineering and the pursuit of leanness, the more gloomy perspective gained currency in the popular managerial literature. Some indeed have pronounced the end of management.

Emissions-foreign trade nexus: establishing the need to harmonize environment and economics in RCEP

PurposeThis article investigates the impact of foreign trade on carbon emissions of the member countries of the largest trade bloc, the Regional Comprehensive Economic Partnership (RCEP). Design/methodology/approachThe aggregate bilateral trade with members of RCEP during the period 1991–2020 was considered for analysis. The study also examines the impact of foreign trade (between member countries) on economic development, represented by GDP per capita. Dumitrescu–Hurlin panel Granger causality test was conducted to understand the impact of foreign trade on GDP per capita and carbon emissions.FindingsResults indicate that though foreign trade is heterogeneously Granger causing GDP per capita, it also aggravates carbon emissions in RCEP bloc.Originality/valueThe study is of significance to the policymakers in the member countries as it provides evidence to include climate impact in trade agreements. The wealthier RCEP member countries can support the green transition of low-income countries through transfer of eco-friendly technologies.
A Miocene cetacean vertebra showing a partially healed longitudinal shear-compression fracture, possibly the result of domoic acid toxicity or failed predation

CT-scans of a cetacean pathological vertebra from the Calvert Formation of the Miocene Chesapeake Group of Maryland, show features characteristic of a shear-com-pression fracture with comminution and significant periosteal reaction. The etiology of the injury suggests an intense hyperflexion of vertebrae in at least the lumbar region of the axial column. The trauma was sufficiently forceful to break much of the lower two-fifths of the centrum away from the anterior end of the body of the vertebra. However, the trauma was not immediately fatal as significant fusion of fragmented elements was well underway at the time of death. Much of the lateral and ventral surfaces of the centrum are covered with a thick layer of periosteal reactive bone. This reactive periosteal bone growth could be due to spondyloarthritis, infection, or from the traumatic event itself, if the direct muscle attachments on the vertebra were avulsed. A single megatoothed shark tooth from Otodus megalodon was found with the vertebra. It is not known if the tooth came to be there serendipitously, or if it was associated predatory shark or macroraptorial physeteroid. In spite of extant cetaceans being subjected to anthropogenically-induced trauma, which include vessel-strike blunt force injuries of many different kinds, shear-compression fractures and periosteal reactions like the ones detailed here have not yet been reported in extant cetaceans. Therefore, we consider the fracture as likely due to an impact from a predator, such as Otodus megalodon , or possibly from seizures due to a harmful algal bloom and resulting domoic acid toxicity. In either scenario, the cetacean survived.
Search for the Higgs boson produced in association with a Z boson and decaying to a pair of bottom quarks with the ATLAS experiment at LHC

Search for the Higgs boson produced in association with a Z boson and decaying to a pair of bottom quarks, where the Z boson decays to two neutrinos. The thesis focuses on two works: one is identification jets originated from b-quarks with the help of b-tagging algorithms, the other is to select the events with high missing transverse energy from the decays of Z boson to two neutrinos using the triggers. The selection is performed to select the signal from Higgs boson, then signal and background outputs are used in the statistical analysis to estimate the significance of Higgs boson signal, the systematic uncertainties are also included.
The Role of Alternative Electron Pathways for Effectiveness of Photosynthetic Performance of Arabidopsis thaliana, Wt and Lut2, under Low Temperature and High Light Intensity

A recent investigation has suggested that the enhanced capacity for PSI-dependent cyclic electron flow (CEF) and PSI-dependent energy quenching that is related to chloroplast structural changes may explain the lower susceptibility of lut2 to combined stresses—a low temperature and a high light intensity. The possible involvement of alternative electron transport pathways, proton gradient regulator 5 (PGR5)-dependent CEF and plastid terminal oxidase (PTOX)-mediated electron transfer to oxygen in the response of Arabidopsis plants—wild type (wt) and lut2—to treatment with these two stressors was assessed by using specific electron transport inhibitors. Re-reduction kinetics of P700+ indicated that the capacity for CEF was higher in lut2 when this was compared to wt. Exposure of wt plants to the stress conditions caused increased CEF and was accompanied by a substantial raise in PGR5 and PTOX quantities. In contrast, both PGR5 and PTOX levels decreased under the same stress conditions in lut2, and inhibiting PGR5-dependent pathway by AntA did not exhibit any significant effects on CEF during the stress treatment and recovery period. Electron microscopy observations demonstrated that under control conditions the degree of grana stacking was much lower in lut2, and it almost disappeared under the combined stresses, compared to wt. The role of differential responses of alternative electron transport pathways in the acclimation to the stress conditions that are studied is discussed.
A Digital Video and Text Messaging Intervention to Support People With Chronic Pain During Opioid Tapering: Content Development Using Co-design

Background People living with chronic pain report that tapering prescribed opioids is challenging and more support is needed. In our formative research, consumers indicated that mobile health (mHealth) technology could be an acceptable form of support for opioid tapering and may improve tapering self-efficacy. Objective We aimed to evaluate and improve the content of an mHealth intervention before pilot-testing, based on consumer and clinician feedback. Methods Participants were 12 consumers and 12 clinicians who evaluated an initial draft of a video script and 90 SMS text messages. Consumers and clinicians rated the appropriateness and likely usefulness (consumers) or likely effectiveness (clinicians) of a video script and a random selection of 15 SMS text messages using a 5-point Likert-type scale (1=totally disagree; 5=totally agree). Each draft SMS text message was reviewed by 2 consumers and 2 clinicians. Texts were deemed acceptable for inclusion in the pilot intervention only if the summed participant ratings of text appropriateness and usefulness or effectiveness were ≥8. Participants were also invited to provide open-text feedback on the draft script and SMS text messages. Results Consumers generally agreed that the draft video script and text content were likely to be appropriate (video: mean 4.4, SD 0.52; text: mean 4.3, SD 0.79) and useful (video: mean 4.3, SD 0.65; text: mean 4.2, SD 0.84). Similarly, clinicians generally agreed that the draft video script and text content were likely to be appropriate (video: mean 4.5, SD 0.67; text: mean 4.4, SD 0.81) and effective (video: mean 4.0, SD 0.43; text: mean 4.3, SD 0.76). Overall, 77% (69/90) of the draft texts met the threshold rating for acceptability for inclusion in the pilot test of mHealth intervention by consumers, and 82% (74/90) met the threshold for acceptability by clinicians. Consumers' and clinicians’ ratings were used to rank order the texts. The top 56 draft texts (all meeting the threshold levels of acceptability) were selected for inclusion in the pilot intervention. When consumer or clinician feedback was provided, the texts meeting the criteria for inclusion in the pilot were further revised and improved. Feedback on the video script was also used to further improve the acceptability of the video script before pilot-testing the intervention. Conclusions This study describes the process by which a 28-day mHealth intervention to support patients with chronic pain to taper opioid medications was evaluated and improved before pilot-testing. The mHealth intervention consisted of a 10-minute psychoeducational video about pain and opioid tapering and 56 unique SMS text messages providing information and reassurance (texts delivered twice per day for 28 days). Having established that the content of the mHealth intervention is acceptable to both consumer and clinician groups, the mHealth intervention will be piloted in future research.
Direct observation of ferroelectric domains created by Wigner crystallization of electrons in α-[bis(ethylenedithio)tetrathiafulvalene]2I3

The organic conductor α-[bis(ethylenedithio)tetrathiafulvalene]2I3 undergoes a ferroelectric transition due to the Wigner-crystal-like charge ordering. The present paper reports the direct observation of 180° polar domains growing in the ferroelectric phase by means of optical second-harmonic generation interferometry. Mapping observation of the nonlinear optical interference revealed the development of large polar domains, illustrating a strong tendency of single-domain growth in the ferroelectric compound. The domain structures were varied when the crystal was annealed above the transition temperature and recooled into the ferroelectric phase. The variation indicates the mobile nature of the domains in the ferroelectric organic conductor.
Exploration an the Search for Origins: A Vision for Ultraviolet-Optical-Infrared Space Astronomy

Public support and enthusiasm for astronomy have been strong in the final decades of the twentieth century. Nowhere is this better demonstrated than with the Hubble Space Telescope (HCT), a grand endeavor, which is enabling astronomers to make giant strides in understanding our universe, our place in it, and our relation to it. The NASAs first infrared observatory, the Space Infrared Telescope Facility (SIRTF), promises to take the crucial next steps towards understanding the formation of stars and galaxies. Toward their completion, the HST and Beyond Committee identifies major goals, whose accomplishment will justify a commitment well into the next century: (1) the detailed study of the birth and evolution of normal galaxies such as the Milky Way; (2) the detection of Earth-like planets around other stars and the search for evidence of life on them; (3) NASA should develop a space observatory of aperture 4m or larger, optimized for imaging and spectroscopy over the wavelength range 1-5 microns; and (4) NASA should develop the capability for space interferometry.
Corporate Social Responsibility as a Factor Promoting Customer Loyalty in the Latvian Retail Sector

The retail sector is an important engine of the national economy and an indicator of the development of the national economy. Over the last ten years, the total retail turnover index has increased by 31%, which highlights the acquisition of competitive advantages. Businesses need to fight strategically for consumers in an environment where information and services are widely available. Promoting customer loyalty is important for companies, but with the realization of responsible and sustainable operations, corporate social responsibility is one of the ways to promote it. It is important to understand how important corporate responsibility is to consumers and what corporate social responsibility activities are now important to consumers to draw conclusions about their impact on customer loyalty. The aim of the current research is to identify corporate social responsibility activities that promote customer loyalty in the Latvian retail sector. In order to achieve the aim of the work, the following tasks have been set: (1) to study theoretical aspects of corporate social responsibility and customer loyalty; (2) to develop a questionnaire to assess public opinion on the importance of corporate social responsibility in the food retail sector and to conduct an in-depth interview to find out the opinion on the results of the questionnaire in practice;(3) to identify the corporate social responsibility activities that are important to society and promote the loyalty. The research question put forward is: What corporate social responsibility activities affect customer loyalty? For analysis of statistical data, the authors use such methods as internal coherence analysis (Cronbach's alpha), frequency analysis, ranking, factor analysis, graphical analysis. In order to identify the factors influencing corporate social responsibility in the Latvian retail sector, a survey was carried out. As a result of factor analysis a scheme of corporate social responsibility activities was developed for companies in the food retail sector, grouping together the most important directions and activities of corporate social responsibility for consumers in order to promote the customer loyalty. Keywords: customer loyalty, corporate social responsibility, retailing, competitiveness, corporate citizenship
Nutritional and phenotypic variations among newly selected African eggplant (Solanum aethiopicum L.)

African eggplant (Solanum aethiopicum L.) is an important but underutilized leafy and fruit vegetable. Systematic characterization of available eggplant accessions for morphological and nutritional traits is paramount to their genetic improvement. This study characterized the diversity among selected S. aethiopicum accessions from Nigeria to identify promising genotypes for future breeding activities in the region. Twenty new purified African eggplant accessions collected from farmers’ fields were characterized using morphological and nutritional descriptors. The accessions varied significantly in qualitative, quantitative and nutritional parameters. Top performers for selected yield-contributing traits and nutritional parameters were NHEPA54, NHEPA39-1, NHEAP10, NHEPA10, NHEPA1, NHEPA56, NHEPA23 for vitamin C, iron, calcium, days to flowering, number of branches, plant height at maturity and number of fruits per plant respectively. The first four principal components accounted for 72.42% of total variability. The first principal component with the largest variation (28.77%) was loaded with number of branches, plant height at maturity, number of fruits per cluster, number of fruits per plant and fruit width. A significant positive association was exhibited between iron and yield-increasing traits such as number of fruits per plant (r = 0.532) and number of fruits per cluster (r = 0.551). Plant height at maturity positively correlated with vitamin C (r = 0.492) indicating predictable success in selecting top-performing eggplant genotypes combining high-yield potential and nutritional content. Top-performing eggplant genotypes identified in this study could be deployed as donors for a hybridization programme to develop new eggplant varieties with higher yield potential and improved nutritional quality.
Control-oriented dynamic identification modeling of a planar SOFC stack based on genetic algorithm-least squares support vector regression

For predicting the voltage and temperature dynamics synchronously and designing a controller, a control-oriented dynamic modeling study of the solid oxide fuel cell (SOFC) derived from physical conservation laws is reported, which considers both the electrochemical and thermal aspects of the SOFC. Here, the least squares support vector regression (LSSVR) is employed to model the nonlinear dynamic characteristics of the SOFC. In addition, a genetic algorithm (GA), through comparing a simulated annealing algorithm (SAA) with a 5-fold cross-validation (5FCV) method, is preferably chosen to optimize the LSSVR’s parameters. The validity of the proposed LSSVR with GA (GA-LSSVR) model is verified by comparing the results with those obtained from the physical model. Simulation studies further indicate that the GA-LSSVR model has a higher modeling accuracy than the LSSVR with SAA (SAA-LSSVR) and the LSSVR with 5FCV (5FCV-LSSVR) models in predicting the voltage and temperature transient behaviors of the SOFC. Furthermore, the convergence speed of the GA-LSSVR model is relatively fast. The availability of this GA-LSSVR identification model can aid in evaluating the dynamic performance of the SOFC under different conditions and can be used for designing valid multivariable control schemes. 概要研究目的为了同时预测固体氧化物燃料电池(SOFC)的电压、 温度动态特性和设计控制器, 建立SOFC的控制相关动态辨识模型。 创新要点为了建立SOFC 更精确的最小二乘支持向量回归机(LSSVR)动态模型, 采用遗传算法(GA)优化LSSVR 的参数。 所建GA-LSSVR 模型可同时预测SOFC 的电压和温度动态特性。 研究方法1. 分析SOFC 的电化学和能量平衡子模型。 2. 利用所选择的最优LSSVR 参数, 建立了SOFC的GA-LSSVR 动态辨识模型。 通过仿真分析和比较, 验证了所建模型的有效性(图3 和4)。 3. 利用所建模型的预测结果, 与模拟退火算法优化最小二乘支持向量回归机(SAA-LSSVR)和5 折交叉验证最小二乘支持向量回归机(5FCV-LSSVR)模型的预测结果进行了比较, 表明所建立的GA-LSSVR 模型具有较高的预测精度(表3 和4)。 重要结论通过比较SAA-LSSVR 和5FCV-LSSVR 模型的预测结果, 发现所建GA-LSSVR 模型具有较好的预测性能和精度。 基于所建立的GA-LSSVR 模型可进行有效的多变量控制器设计。
