The influence of learner behaviour on beginner teachers’ perceptions of their own credibility
Authors: Reddy Tanita , Woest Yolandi 
Published: December 2021

Traditionally, teacher credibility has been influenced by how others perceive them. However, exploring teachers’ own perceptions of their credibility through the observation of learner behaviour may prove to be meaningful to teacher credibility. The aim of this study was to explore Intermediate Phase beginner teachers’ perceptions of their own credibility based on displayed learner behaviour in their classrooms. This qualitative study was presented through a case study research design. Eight Intermediate Phase beginner teachers were purposively selected. The data collection techniques used were interviews and observations. Semi-structured interviews and a researcher journal were used as data collection instruments. The data were analysed using inductive thematic data analysis. The conceptual framing of this study was underpinned by a modified theoretical model developed by McCroskey, Valencic and Richmond (2004). The findings showed that teachers’ perceptions of their own credibility were fluid as they engaged with various learners’ behaviour, which was used as a form of feedback during lessons and this feedback impacted teachers’ reactions and decisions to classroom situations. Ultimately, teachers’ perceptions of their own credibility focused on their immediacy, trustworthiness, competence and dynamism displayed in their practices.

Rights and responsibilities are enshrined in the Constitution of the Republic of South Africa but are disregarded in many ways in the education of young children. This article focuses on comparing the experiences and perceptions of Grade 3 children of their rights and responsibilities across diverse school settings. The comparison of data sets highlighted reciprocity in children’s experiences and showed challenges and gaps in children’s education of rights and responsibilities. This research was qualitative in nature, using a multiple case study design with ninety-six (n=96) participating children. Data gathering occurred through interviews, observation, documents, field notes and visual artefacts made by the participating children. The findings were that education firstly advances children’s understanding and knowledge of their rights and responsibilities. Secondly, basic needs of children have a significant effect on their understanding of their rights and responsibilities with the emphasis on rights. Children’s perceptions of their rights and responsibilities were juxtaposed to assist in finding similarities and differences in their perceptions. Thirdly, the participant children understood that people have needs and rights; they communicated that these rights must be recognised to safeguard a sustainable standard of life.

Published: December 2021

In this study, the chest computed tomography (chest CT) findings of patients with suspected COVID-19 admitted to the
emergency department were examined, and it was evaluated whether chest CT should be performed in each patient with suspected
COVID-19. Patients with suspected COVID-19 and who had chest CT were included in the study. Swab samples were taken from the
throat and nose of the patients for RT-PCR. Chest CT was applied to the patients according to the physician's decision. A team of 5
radiologists evaluated the chest CT reports. 251 patients were included in the study. In the chest CT of 154 patients (61.4%), findings
compatible with COVID-19 pneumonia were found. The number of patients who were found to have COVID-19 by PCR test result was
138 (55.0%). The most common pneumonia finding was found to be ground glass (55.8%) Most of the patients had findings in both
lungs (25.9%). Less frequently, the right lung (23.1%) was affected. The least affected was the left lung (14.7%). The most frequently
affected part of the left lung was the lower lobe. In emergency services, the use of chest CT after the physical examination of the
patients with suspected lung involvement may be useful in the diagnosis of COVID-19.

Abstract
Background: Non-attendance to scheduled hospital outpatient appointments may compromise healthcare resource planning, which ultimately reduces the quality of healthcare provision by delaying assessments and increasing waiting lists. We developed a model for predicting non-attendance and assessed the effectiveness of an intervention for reducing non-attendance based on the model.Methods: Candidate models were built using retrospective data from appointments scheduled between January 1, 2015, and November 30, 2018, in the dermatology and pneumology outpatient services of the Hospital Municipal de Badalona (Spain). The predictive capacity of the selected model was then validated prospectively with appointments scheduled between January 7 and February 8, 2019. The effectiveness of selective phone call reminders to patients at high risk of non-attendance according to the model was assessed on all consecutive patients with at least one appointment scheduled between February 25 and April 19, 2019. Patients identified by the model as high risk of non-attendance were randomly assigned to either a control (no intervention) or intervention group, the last receiving phone call reminders one week before the appointment.Results: Models were trained and selected using 33,329 appointments in the dermatology service and 21,050 in the pneumology service. Average results for specificity and balanced accuracy for the prediction of non-attendance were 79.90% and 73.49% for dermatology, and 71.38% and 64.61% for pneumology outpatient services. The prospective validation showed a specificity of 78.34% (95%CI 71.07, 84.51) and balanced accuracy of 70.45% for dermatology; and 69.83% (95%CI 60.61, 78.00) for pneumology, respectively. The effectiveness of the intervention was assessed on 1,311 individuals identified as high risk of non-attendance according to the selected model. Overall, the intervention resulted in a significant reduction in the non-attendance rate to both the dermatology and pneumology services, with a decrease of 50.61% (p<0.001) and 39.33% (p=0.048), respectively.Conclusions: The risk of non-attendance can be adequately estimated using patient information stored in medical records. The patient stratification according to the non-attendance risk allows prioritizing interventions, such as phone call reminders, to effectively reduce non-attendance rates.

Published: December 2021

Abstract
Determining causal effects of interventions onto outcomes from observational (non-randomized) data, e.g., treatment repurposing using electronic health records, is challenging due to underlying bias. Causal deep learning has improved over traditional techniques for estimating individualized treatment effects. We present the Doubly Robust Variational Information-theoretic Deep Adversarial Learning (DR-VIDAL), a novel generative framework that combines two joint models of treatment and outcome, ensuring an unbiased estimation even when one of the two is misspecified. DR-VIDAL uses a variational autoencoder (VAE) to factorize confounders into latent variables according to causal assumptions; then, an information-theoretic generative adversarial network (Info-GAN) is used to generate counterfactuals; finally, a doubly robust block incorporates propensity matching/weighting into predictions. On synthetic and real-world datasets, DR-VIDAL achieves better performance than other non-generative and generative methods. In conclusion, DR-VIDAL uniquely fuses causal assumptions, VAE, Info-GAN, and doubly robustness into a comprehensive, performant framework.

Denoising of Motion Artifacts in EEG Signals using DWT-EMD Approach
Authors: Goru Hema Kumar , Ramakrishna B , Panigrahy Damodar 
Published: December 2021

Abstract
Surface Electroencephalography (EEG) is a non-invasive technique used for monitoring and recording the electrical activity of the human brain. Typically, the raw and unprocessed EEG signals are contaminated with various types of physiological artifacts originated from eye blinks and limb moments due to long haul monitoring. The removal of such low frequency motion artifacts in preprocessing techniques could potentially improves the accuracy of diagnosis. In this viewpoint, a multi-resolution analysis such as discrete wavelet transform (DWT) with empirical mode decomposition (EMD) is presented to filter the motion artifacts from the EEG signal. Initially, the low frequency components were separated from EEG signal using DWT decomposition technique and the same are passed to EMD to find intrinsic mode functions (IMFs). Using iterative thresholding algorithm the noisy IMF’s are filtered out, and these denoised approximated components are utilized to reconstruct the motion artifact free EEG signal. The proposed technique shows 15.3218 dB of △SNR, 41.9859% of Relative root mean square error (RRMSE) and the percentage reduction in correlation coefficient (%η) of 65.8213 by using Physionet data base.

Authors: Ou Zhenfei , Zhang Xuejuan 
Published: December 2021

Abstract
Although the pathogenesis of type 1 diabetes mellitus (T1D) and acute myocardial infarction (AMI) remains unclear. We investigated the key genes and signaling pathways common to T1D and AMI. First, we screened differentially expressed genes (DEGs) co-expressed by T1D and AMI through gene expression synthesis (GEO) database and text mining. David database was used for enrichment and functional analysis of selected genes. The interaction between proteins (PPI) was created using STRING and Cytoscape software. MCODE is used for module analysis of PPI network. A total of 74 human genes that met the criteria were found in T1D and AMI. The first 10 central genes include STAT3, ITGAM, MMP9, ERBB2, MAPK3, FOS, MYD88, MAPK1, TFRC and TNFRSF1A.The establishment of the aforementioned key genes might serve as novel biomarkers for precision diagnosis and providing medical treatment for the occurrence of AMI in T1D patients in the future.

Published: December 2021

Abstract
Objective: CI (cochlear implantation) candidacy is somewhat controversial in severe hearing loss among tonal mandarin-speaking patients. To assess the relationship between pure tone audiometry (PTA) and speech recognition score (SRS), with and without hearing aid amplification, among patients who did not meet the NIH criteria of CI candidacy in tonal language mandarian-speaking countries, especially those with severe hearing loss (70 dB HL < 4FPTA(0.5, 1, 2, 4 KHz) ≤ 90 dB HL) Materials and Methods: A total of 414 patients with sensorineural hearing loss with 774 ears were reviewed retrospectively in a tertiary referral center. The Mandarin Monosyllable Recognition Test (MMRT) was used to evaluate the SRS of these ears. Results: 31% (10/32) of the 32 ears with severe hearing loss, 70-90 dB HL, still showed poor speech recognition (SRS<30%) after hearing aid amplification, while 71% (46/65) of the 65 ears with profound hearing loss, > 90 dB HL, showed poor speech recognition with hearing aid amplification. Conclusions: The speech audiometry with Mandarin Monosyllable Recognition Test (MMRT) helped identify those patients whose 4FPTA< 90 dB HL fell outside the CI candidacy criteria of NIH in tonal language mandarin-speaking countries but showed significantly poor (SRS< 30%) speech recognition performance.

Abstract
BackgroundTitanium dioxide (TiO2) with nanofractions is increasingly applied in food products as a food additive, which makes consumers under the health risks of titanium dioxide nanoparticles (TiO2-NPs) oral exposure. The recent ban of food additive TiO2 (E171) use in France aggravated public controversy on safety of orally ingesting TiO2-NPs. This work aimed to determine biological effects of TiO2-NPs (38.3 ± 9.3) oral consumption (100 mg/kg bw, 10 days) on TNBS-induced colitis mice and healthy mice, and the additional vitamin E administration was also conducted to explore the possible mechanism of TiO2-NPs on colitis development.ResultsOral consumption of TiO2-NPs exacerbated oxidative stress status in colitis mice by decreasing the colonic glutathione (GSH) and total glutathione (T-GSH) levels, however, TiO2-NPs administration repaired the dysbacteriosis of colitis mice, and downregulated the Toll-like receptors (TLRs), nuclear factor kappa-B (NF-κB) signal pathway and inflammatory factor (IL-1β and TNF-α) transcription levels in colon tissue, which finally decreased the TNF-α expression level and participated in the mitigation of colitis symptoms. Moreover, further vitamin E intervention after TiO2-NPs consumption could relieve the oxidative stress status (mainly by scavenging reactive oxygen species, ROS) and the inflammatory factor over-transcription in colonic epithelium of colitis mice, but the effect of TiO2-NPs on dysbacteriosis repair would not be further changed by Vitamin E. At last, TiO2-NPs induced oxidative stress status and increased NF-κB signal transcription level in colonic epithelium, which increased daily disease activity index (DAI) score and caused mild mucosal inflammatory cell infiltrate in healthy mice. ConclusionOur present work showed that oral TiO2-NPs administration indeed induced oxidative stress and made an adverse effect on the development of colitis, but TiO2-NPs could also downregulate the NF-κB signal transduction level by repairing gut dysbacteriosis, which made a predominant role in alleviating colitis. On the other hand, it should also be noticed that TiO2-NPs oral ingestion caused potential colonic inflammation risks in healthy mice.

Published: December 2021

Abstract
In order to investigate the effective method of COD removal from desulfurization wastewater, acid-modified fly ash (AFA) and base-modified fly ash (BFA) were prepared by impregnation method. Then, magnetic coagulants (Fe-AFA, Fe-BFA) were prepared by mixing the modified fly ash with magnetic components. The structural characterization results showed that the specific surface area and the porosity of fly ash were obviously increased after modification. Fe-AFA magnetic coagulant has the best performance and superparamagnetism. Under the same experimental conditions, the maximum COD removal amounts of FA, BFA, AFA, Fe-BFA and Fe-AFA were 2.180, 3.209, 4.631, 3.710 and 5.687 mg/g, respectively. The COD removal amount of Fe-AFA was increased by 112.43% compared with the raw FA. The quasi-second-order kinetic and Langmuir equation could well fit the COD coagulation process of five coagulants. After five cycles, the COD removal amount of Fe-AFA was 2.735 mg/g, and the removal rate still reached 67.53%. These findings provide a feasible method for the treatment of fly ash from coal-fired power plants and the preparation of highly efficient COD trapping magnetic coagulants.

Published: December 2021

Abstract
The present study was to investigate the therapeutical effects and mechanisms of Asiatic acid from Potentilla Chinensis against alcoholic hepatitis. Rats were intragastrically fed with alcohol for 12 weeks to induce alcoholic hepatitis and then treated with various drugs for further 12 weeks. The results showed that Asiatic acid significantly alleviated liver injury caused by alcohol in rats, as evidenced by the improved histological changes and the lower levels of AST, ALT, and TBIL. Besides, Asiatic acid significantly enhanced the activity of ADH and ALDH, promoting alcohol metabolism. Asiatic acid suppressed CYP2E1 activity and NADP+/NADPH ratio, resulting in low ROS production. Further study revealed that Asiatic acid markedly reduced hepatocyte apoptosis by regulating the expression levels of the caspase and Bcl-2 families. Moreover, Asiatic acid could regulate the Keap1/Nrf2 and NF-κB signaling pathway, attenuating oxidative stress and inflammation as a result. Interestingly, the comprehensive analysis of transcriptomics and metabolomics indicated that Asiatic acid regulated the gene expression of Gpat4 and thereby affected the biosynthesis of the metabolites (1-acyl-Sn-glycerol-3-phosphocholine, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine), regulating the glycerophospholipid metabolism pathway and ultimately ameliorating hepatocyte damage. In conclusion, this study demonstrates that Asiatic acid can ameliorate alcoholic hepatitis by modulating the NF-κB and Keap1/Nrf2 signaling pathways and the glycerophospholipid metabolism pathway, which may be developed as a potential medicine for the treatment of alcoholic hepatitis.

Abstract
Hearing loss in children is common especially in NICU with consequences of worse outcomes in speech, language, education, social functioning, cognitive abilities, and quality of life. Whether neonatal pain is link to increase risks for hearing loss remains to be explored. Here, we implemented Complete Freund's adjuvant (CFA) plantar injection and needle prick model to mimic neonatal pain in NICU during critical period of hearing development. Auditory brainstem response (ABR) test was used to determine the hearing threshold at 4w and 8w postnatal. Sufentanil and Oxycodone were used as analgesic to treat neonatal pain. Hair cell and ribbon synapse stanning were performed to detect cochlear function. Golgi-cox staining and BDNF immunofluorescence of auditory cortex were performed to determine dendritic spine pruning in auditory cortex. The dendritic pruning related protein CaMKII and Rac1/2 level were detected by western blot. We found that CFA induced neonatal pain and ABR threshold increased at 4w and 8w postnatal and the impairment were attenuated after analgesic administration. Neither the inner hair cell (IHC) nor the synapse of CFA mice was damaged in cochlear. CFA mice showed increased dendritic spine density at auditory cortex and reduced BDNF level. Furthermore, Rac1/2 and CaMKII might contributed to the disrupt dendritic spine pruning. Our study suggested that neonatal pain could induced hearing impairment in adulthood ascribed to the reduced BDNF level and AC dendritic spine pruning deficiency, optimal analgesic in early-life could beneficial for hearing development.

Published: December 2021

Abstract
Fractional derivatives provide a prominent platform for various chemical and physical system with memory and hereditary properties, while most of the previous differential systems used to describe dynamic phenomena including oscillation quenching are integer order. Here, effects of fractional derivative on the transition process from oscillatory state to stationary state are illustrated for the first time on mean-filed coupled oscillators. It is found the fractional derivative could induce the emergence of a first-order discrete transition with hysteresis between oscillatory and stationary state. However, if the fractional derivative is smaller than the critical value, the transition will be invertible. Besides, the theoretical conditions for the steady state are calculated via Lyapunov indirect method which probe that, the backward transition point is unrelated to mean-field density. Our result is a step forward in enlightening the control mechanism of explosive phenomenon, which is of great importance to highlight the function of fractional-order derivative in the emergence of collective behaviors on coupled nonlinear model.
