Multicultural Values Represented in English Textbooks for Indonesian Learners: A Social Semiotic Analysis
Authors: Azizah Aulia Rahmatika Nur , Andriyanti Erna
Published: May 2023

The social semiotic analysis in this study aims to (1) reveal what multicultural values are found in ELT textbooks for ninth-grade learners, (2) explain how the texts and the images in the analyzed textbooks present multicultural values, and (3) uncover how social semiotics dimensions can decode multicultural values. This study finds that among four multicultural values discovered in the textbooks, responsibility to the world community has the most frequent appearance while respect for human dignity and universal human rights has the least frequent appearance. Those values are presented denotatively and connotatively through texts, images, and texts-images. Based on the findings, textbook authors are recommended to include more content and add learning activities that facilitate discussions and reflections on multiculturalism. In addition, this research suggests that English teachers who use these textbooks add learning activities that enable students to discuss multicultural values since, in this study, multicultural values are mainly presented connotatively.
Consumption of acetaminophen during pregnancy: a survey on knowledge, attitudes and practices of Lebanese women
Authors: Zeid Berthe Abi , AlHoyeck Mary , Lahoud Nathalie
Published: May 2023

Objectives
Use of APAP during pregnancy is safe however certain practices have been related to the risk of neurodevelopmental disorders in offspring. Therefore, the present study was conducted to assess the knowledge, attitudes and practices (KAP) of women towards the use of APAP during pregnancy and associated factors.
Methods
This cross-sectional study was carried out between May 15 and August 31, 2020, among pregnant Lebanese women and those who gave birth in the last 12 months. Data collection was performed through an online questionnaire. KAP were described and a knowledge score was created in order to assess factors related to the score in a multivariable linear model.
Results
Out of 305 participants, 72.8% had marginal knowledge about the use of APAP during pregnancy. Actually, more than 50% was unable to differentiate between APAP and other pain medications, to determine the maximum recommended daily dose and the minimum time to wait between doses and to specify the potential effects of APAP on both mother and unborn child. A higher level of education was associated with a higher knowledge (β = 2.32, 95%CI=[0.91; 3.73]; p = 0.001). Moreover, women had positive attitudes towards APAP with a perceived risk of low toxicity. Indeed, 70.5% of women used APAP at least once during their pregnancy, of which 63.7% used it safely. Women with higher knowledge, having at least five somatic symptoms and a low socioeconomic level tended to be more APAP users (p < 0.05).
Conclusions for practice
Health professionals have the responsibility to give adequate and personalized advice to women regarding their medicines.
A predisposed motor bias shapes individuality in vocal learning
Authors: Toji Noriyuki , Sawai Azusa , Wang Hongdi , Ji Yu , Sugioka Rintaro , Go Yasuhiro , Wada Kazuhiro
Published: May 2023

The emergence of individuality during learned behavior is a general feature of animal species, yet the biological bases of its development remain unknown. Similar to human speech, songbirds develop individually-unique songs with species-specific traits through vocal learning. By taking advantage of songbirds as a model system for studying the neural basis of vocal learning and development, we utilized F1 hybrid songbirds (Taeniopygia guttata cross with T. bichenovii) to examine the developmental and molecular mechanisms underlying individuality in vocal learning. When tutoring with songs from both parental species, F1 pupils showed vast individual differences in their acquired songs. Approximately 30% of F1 hybrids selectively learned either song of the two parental species, whereas others developed merged songs between the parental species. Vocal acoustic biases during vocal babbling were initially observed as individual differences in songs among F1 juveniles, which were maintained through the sensitive period of song vocal learning. These individual differences in vocal acoustic biases appeared independently from the auditory experience of hearing biological farther’s and passive tutored songs. Furthermore, the idiosyncratic traits of F1 hybrids’ songs were not correlated with peripheral vocal organ morphology. However, we identified unique transcriptional signatures from the glutamatergic neurons projecting from the cortical vocal output nucleus to the hypoglossal nuclei associated with individual differences in the acoustic vocal biases, even at the initial stage of vocal learning. These results indicate that a predisposed motor bias influences the individuality observed when learning new motor skills.

Published: May 2023

Background Xanthogranulomatous cholecystitis (XG) is a rare inflammatory disease of the gallbladder (GB), macroscopic appearance may be confused with gallbladder cancer (GC) making the diagnosis challenging. Laparoscopic cholecystectomy (LC) is considerate the gold standard for the management of benign gallbladder disease however LC in XGC is associated with a high conversion rate to open cholecystectomy with a rate of 10.6 to 80%. The aim of this study was to determinate the rate of laparoscopic cholecystectomy on patients with histopathological diagnosis of CXG and the associated morbidity to the procedure.
Material and methods This study is an observational, retrospective, and cross-sectional study carried out over a period of 18 years in a single institution. Patients underwent to laparoscopic cholecystectomy with histopathological diagnosis of xanthogranulomatous cholecystitis were included. The primary outcome was the rate of conversion to open surgery; secondary outcomes were the morbidity and mortality. The data were reported on percentages and averages. Statistical Package for the Social Sciences (SPSS, version 26) was used to analyze the data. The study was approved by the board of ethical committee in our institution in 2018.
Results We registered 142 patients operated from cholecystectomy with histopathologic results of XGC and 106 surgeries were performed laparoscopically (74.6%); 52 were emergency surgeries (49%) and 54 elective (51%). The conversion rate to open cholecystectomy was 3.7% (4 patients). There were 5 post-surgical complications (4.7%) one biloma, one surgical site infection, and 3 pancreatitis.
Conclusions XGX represents a surgical challenge from diagnosis to surgical management and is associated to a higher number of perioperative complications; nevertheless, a laparoscopic approach is safe in high volume centers with experience in laparoscopy.

Authors: Titus Anoop , Mohamed Safia , Home Madhurima , Baburaj Abiram , Victor Varun , Suresh Mithil Gowda , Crema Karin C , Hasdianda Mohammad Adrian , Amblihalli Vibha , Ray Ayita , Altabaqchali Sayf
Published: May 2023

Background
Left ventricular noncompaction (LVNC) is a structural abnormality of the left ventricular myocardium. It is a relatively rare disease, but with the recent use of widespread echocardiography and advanced imaging techniques like cardiac magnetic resonance imaging (MRI), there is an increased rate of diagnosis of LVNC in healthy adult populations. LVNC can be either sporadic or familial. LVNC has been reported in pregnant women and is thought to be due to physiological remodeling in response to LV loading leading to hyper-trabeculation in the LV myocardium. The most common clinical presentation is dyspnea, followed by New York Heart Association (NYHA) functional class III or IV HF, complicating pregnancies with preterm deliveries and higher rates of Cesarean sections. Management includes diuretics and beta-blockers.
Methods
We conducted an advanced search across three databases and extracted 28 articles containing 33 cases. A stepwise approach was used - title and abstract screening followed by full-text screening. Data extraction was conducted using the Covidence Extraction Tool 2.0. Appraisal of articles was done with Mayo Evidence-Based Practice Center Tool.
Results
The mean age of patients reported was 27 years. 58% were diagnosed before pregnancy. Heart failure was the most common index event, followed by arrhythmia. There was wide variability in echocardiographic criteria, with most patients having mid to reduced EF at the time of presentation. 48% of patients were on anticoagulation. The most common mode of delivery was a Cesarean section.
Conclusion
The prevalence of LVNC in pregnancy is rare, with limited data regarding diagnosis and management with a lot of variability in management and outcomes. Our study demonstrates the need for further research and better reporting of cases.

Published: May 2023

Water, energy and food are inextricably linked in agricultural system. Social and environmental issues arising from socio-economic development pose new challenges for sustainable agricultural development. Achieving sustainable agriculture from the perspective of water, energy and food resource conservation is of critical importance to the national strategy for high-quality development of the Yellow River Basin in China. In this study, the mass productivity and economic productivity of water and energy in agricultural system were considered, and an integrated assessment index system for agricultural system based on the Water-Energy-Food Nexus (WEFN) was proposed in three dimensions: reliability, coordination and resilience. Based on these indicators, the agricultural water-energy-food nexus index (AWEFNI) and integrated risk index (IRI) were performed to assess the current status of agricultural development in the middle and upper reaches of the Yellow River. Results indicate that the AWEFNI in the middle and upper reaches of the Yellow River is increasing year by year, and the level of sustainable agricultural development is improving, but the overall level is lower. The AWEFNI values vary widely among provinces. The reliability of single subsystem in the study area accounts for more than 1/3 of the AWEFNI, with poor water endowment, rich food and energy resource endowments, the coordination of the AWEFN is weakening. The resilience of the third subsystem is gradually declining. The contradiction in water and energy supply and demand in Ningxia is the most prominent among the five provinces, and the level of AWEFN development is the lowest, so the regulation policies should be implemented as soon as possible to promote the synergistic development of AWEFN around the region.

In this study, sepiolite/humic acid/polyvinyl alcohol@ polyaniline (SC/HA/PVA@PANI) composite porous hydrogel adsorbent was synthesized by Pickering emulsion template-in situ chemical oxidative polymerization for adsorption of Cr(VI) from aqueous solution. The in-situ polymerization of aniline at the Pickering emulsion interface and the unique three-dimensional network structure of the hydrogel act as an effective "confinement" for the growth of the polymer. The porous structure of the material acts as a water channel, which effectively accelerates the binding of the adsorbate to the adsorption sites, and significantly improves the adsorption rate and adsorption capacity.The adsorption capacity of PANI for Cr(VI) confined in three-dimensional network of composite porous SC/HA/PVA@PANI hydrogel reached 1180.97 mg/g-PANI, which increased about 27-fold compared the adsorption capacity of pure PANI (43.48 mg/g). It is shown that the experimental design effectively avoids the agglomeration of PANI and improves its potential adsorption performance. In addition, the analysis of FESEM-EDX, FT-IR and XPS spectra before and after adsorption confirmed that the main adsorption mechanisms of Cr(VI) on SC/HA/PVA@PANI included ion exchange, electrostatic attraction and redox reaction. In conclusion, SC/HA/PVA@PANI has good stability and excellent adsorption performance, which is a new type of Cr(VI) ion adsorbent with great potential.

The fundamental issue limiting long-distance and high-speed optical fiber transmission is dispersion. Dispersion impairs system performance, the signal-to-noise ratio (SNR), and the bit error rate (BER). To address this, numerous dispersion modification techniques have been developed. The use of fiber Bragg grating (FBG) is one of the efficient strategies for dispersion compensation. The FBG is frequently used as a filter.

Hymenoepimecis is a genus of Darwin wasps within the Polysphincta genera group (Hymenoptera: Ichneumonidae: Pimplinae) known for being ectoparasitoids of a broad spectrum of spiders. This parasitoid-host interaction results in a modified web known as cocoon web, which provides shelter and support for the wasp during its pupal stage. In this study we describe for first time the interaction between Hymenoepimecis castilloi Padua & Sääksjärvi (Hymenoptera: Ichneumonidae) and the host spider Leucauge mariana Taczanowski (Araneae: Tetragnathidae) in the Colombian Andes. We provide new records of wasp genus distribution and reported the behavioral modifications induced in their spider host. Web modifications were found in the webs of solitary and aggregated parasitized individuals. We found an absence of adhesive spirals and webs that were connected to vegetation by multiple threads in all cocoon webs, which was not seen in webs of non-parasitized spiders. All parasitoid cocoons were observed hanging on a vertical line in the hub of the cocoon web. As previously described for other interactions between spiders and wasps, we believe that this modified web design is related to increased web strength, which favors parasitoid development during the pupal stage.

Backgrounds: The “human leukocyte antigen (HLA) supertype” is a functional classification of HLA alleles, which was defined by structural features and peptide specificities, and has been reportedly associated with the clinical outcomes of viral infections and autoimmune diseases. Although the disparity in each HLA locus was reported to have no clinical significance in single-unit cord blood transplantation (sCBT), the clinical significance of the HLA supertype in sCBT remains unknown.
Methods: The clinical data of 1,603 patients who received sCBT in eight institutes in Japan between 2000 and 2017 were retrospectively analyzed. Each HLA allele was categorized into 19 supertypes, and the prognostic effect of disparities was then assessed.
Results: An HLA-B supertype mismatch was identified as a poor prognostic factor (PFS: hazard ratio [HR] = 1.23, p= 0.00044) and was associated with a higher cumulative incidence (CI) of relapse (HR = 1.24, p = 0.013). However, an HLA-B supertype mismatch was not associated with the CI of acute and chronic graft-versus-host-disease. The multivariate analysis for relapse and PFS showed the significance of an HLA-B supertype mismatch independent of allelic mismatches, and other previously reported prognostic factors.
Conclusion: HLA-B supertype-matched grafts should be selected in sCBT.
Improved Subseasonal-to-Seasonal Precipitation Prediction of Climate Models with Nudging Approach for Better Initialization of Tibetan Plateau-Rocky Mountain Circumglobal Wave Train and Land Surface Conditions

Reliable subseasonal-to-seasonal (S2S) precipitation prediction is highly desired due to the great socioeconomical implications, yet it remains one of the most challenging topics in the weather/climate prediction research area. As part of the Impact of Initialized Land Temperature and Snowpack on Sub-seasonal to Seasonal Prediction (LS4P) project of the Global Energy and Water Exchanges (GEWEX) program, a number of climate models follow the LS4P protocol to quantify the impact of the Tibetan Plateau (TP) land surface temperature/subsurface temperature (LST/SUBT) springtime anomalies on the global summertime precipitation. We find that nudging towards reanalysis winds is crucial for climate models to generate atmosphere and land surface initial conditions close to observations, which is necessary for meaningful S2S applications. Simulations with nudged initial conditions can better capture the summer precipitation responses to the imposed TP LST/SUBT spring anomalies at hotspot regions all over the world. Further analyses show that the enhanced S2S prediction skill is largely attributable to the substantially improved initialization of the Tibetan Plateau-Rocky Mountain Circumglobal (TRC) wave train pattern in the atmosphere. This study highlights the important role that initial condition plays in the S2S prediction and suggests that data assimilation technique (e.g., nudging) should be adopted to initialize climate models to improve their S2S prediction.
Record-breaking Barents Sea Ice Loss Favors to the Unprecedented Summertime Extreme Heatwave in 2021 over Western North America by Enhancing Rossby Wave Ridge
Authors: Wei Yuying , Huang Fei , Chen Zheng
Published: May 2023

A record-setting extreme heatwave occurred over western North America (WNA) in the summer of 2021, which was associated with an extreme atmospheric Rossby wave ridge (ARR) over WNA and a minimum record event of the pre-winter Barents Sea ice concentration. We identify the temporal-spatial remote effect and investigate how the sea ice loss in the Barents Sea modulates the intensity of the ARR and extreme heatwaves by analyzing the reanalysis data. Our results suggest that atmospheric wave activity flux associated with Barents Sea ice loss (BSIL) in pre-winter transferred wave energy towards the circumglobal teleconnection (CGT)-like wave trains, increasing the wave amplitude and enhancing the ARR over WNA. Meanwhile, the weakening of the jet streams drives atmospheric subsidence and increases the shortwave radiation, leading to anticyclonic anomalies over WNA and the enhancement of the ARR. Both the CGT-like wave trains and the weakened jet streams contribute to the synergistic effect of the enhancing ARR and more frequent extreme heatwaves. And the BSIL serves as a pioneer predictor for the predictions of extreme heatwaves 6 months in advance. The above analysis can improve the prediction skills of extreme heatwaves over WNA, possibly predicting more precisely.

Background The relationships of medical workers, including doctors-themselves, doctors-patients, and doctors-colleagues, have been of great concern. Medical humanities are a valuable tool to maintain these relationships. Narrative medicine is one of the subjects in medical humanities but has rarely been applied in China. This study evaluates the current educational programme for narrative medicine and provides recommendations for designing future education.Methods This study was based on mixed methods and design-based studies. We enrolled medical bachelors in our educational programme into the exposure group or the control group. Then, we analysed their capabilities using Chinese-specific scales of empathy, self-reflection, and communication and used semi-open questions to collect the students’ perspectives. A final list of recommendations for designing narrative medicine education was created by an iterative process. The process included simplified thematic analysis of the students’ perspectives, modification of the drafts in focus groups, and evaluation of the final list.Results The distribution of students’ empathy, communication, and self-reflection became more right skewed, although no general significant differences were found. Improvements in empathy, self-reflection, and awareness of human care were found in students’ feedback. A list of recommendations combining general principles and activities was created.Conclusions Although improvement was found, the development of better narrative medicine education is expected, which may be improved by designing educational programmes.Trial registration: Not applicable

Background: Although the COVID-19 pandemic has been brought under control, strict infection and control measures are still recommended for healthcare workers to prevent the rebound of the pandemic. However, adherence to prevention measures might be decreased due to fatigue caused by the prolonged duration of the pandemic.
Objective: This study examines the effects of social-cognitive factors suggested in the health action process approach on adherence to infection prevention and control measures among Chinese healthcare workers two years after the onset of the COVID-19 pandemic.
Methods: A total of 521 healthcare workers from two COVID-19 designated hospitals in Beijing participated in the survey in August 2021 and reported risk perception, outcome expectance, action self-efficacy, preventive intention, action control, and prevention behaviors during work.
Results: 1) Action self-efficacy and outcome expectancy were positively associated with intention to adhere to preventive measures. 2) Action control mediated the association between intention and preventive behaviors during work.
Conclusion: Social-cognitive factors such as action self-efficacy, action control, and intention should be addressed to improve healthcare workers’ adherence to infection and control measures during the COVID-19 pandemic.
