Investigating Student Teachers’ Perceptions of English as a Lingua Franca and Its Teaching in Mainland China

ABSTRACT The significance of English as a lingua franca (ELF) has been promoted widely in English language teaching worldwide and has driven scholarly attention to English language teachers in Mainland China. However, little attention has been paid to English teachers’ perceptions of ELF-informed teaching during the pre-service stage of their careers. To narrow the gap, the present study aims to investigate English student-teachers’ perceptions of ELF and its teaching in a national key Chinese normal university through a questionnaire and semi-structured interviews. Results indicated that the participants held an insufficient understanding of ELF, and lacked support in their teacher education programmes regarding how to implement ELF-informed teaching practices. Additionally, the study revealed some contextual challenges encountered by the participants in relation to ELF-informed teaching. The study concludes with suggestions about promoting student English teachers’ ELF awareness and developing ELF-informed pedagogies in China.
Embedded Regions 1 and 2 Field‐Aligned Currents: Newly Recognized From Low‐Altitude Spacecraft Observations

Regions 1 and 2 (R1 and R2) field‐aligned currents (FACs), manifestations of large‐scale convection in Earth's magnetosphere‐ionosphere (M‐I) system, often contain intense FAC layers of mesoscale latitudinal width near the R1/R2 interface. We refer to such layers as “embedded” R1 and R2 FACs. Likely resulting from enhanced magnetosphere‐ionosphere (M‐I) convection, these FACs may indicate M‐I configuration change and contribute significantly to substorm current wedges. We present several events in which embedded FACs were observed by low‐altitude spacecraft in the ionosphere. All the events occurred during active geomagnetic conditions or a substorm growth phase, and most map to an equatorial location on the nightside. When an embedded FAC is upward, it coincides with inverted‐V electron precipitation and a discrete auroral arc. If an upward embedded FAC is in the postmidnight‐to‐dawn sector, a dawnside auroral polarization stream appears immediately poleward of it, so it may be important for ionospheric heating, M‐I convection, and instabilities. Our results establish embedded FACs as a frequently appearing, fundamental phenomenon for understanding and modeling the magnetosphere‐ionosphere system.
Effective wind speed estimation based on a data-driven model of wind turbine tower deflection

The deflection of the wind turbine tower can provide us with rich information about the effective wind speed. In this paper, a new method for effective wind speed estimation is proposed based on tower deflection. The tower vibration model is derived and a subspace identification method is used to identify the model parameters. An online estimator of aerodynamic thrust force based on the identified tower model is designed and then implemented using a Kalman filter together with a recursive least squares algorithm. The estimated aerodynamic thrust force is then used as an input to a neural network estimator, which is trained to invert the aerodynamic thrust force equation and estimate the effective wind speed. In order to show the performance of the proposed estimator, the estimated thrust force and wind speed are compared and verified with a third-party simulation data of a 1.5 MW wind turbine. The comparison shows close agreement between their values.
Response to selection for parasitism of a suboptimal, low‐preference host in an aphid parasitoid

Risks of postintroduction evolution in insects introduced to control invasive pests have been discussed for some time, but little is known about responses to selection or genetic architectures of host adaptation and thus about the likelihood or rapidity of evolutionary shifts. We report here results on the response to selection and genetic architecture of parasitism of a suboptimal, low‐preference host species by an aphid parasitoid, Aphelinus rhamni, a candidate for introduction against the soy bean aphid, Aphis glycines. We selected A. rhamni for increased parasitism of Rhopalsiphum padi by rearing the parasitoid on this aphid for three generations. We measured parasitism of R. padi at generations 2 and 3, and at generation 3, we crossed and backcrossed parasitoids from the populations reared on R. padi with those from populations reared on Aphis glycines and compared parasitism of both R. padi and Aphis glycines among F1 and backcross females. Aphelinus rhamni responded rapidly to selection for parasitism of R. padi. Selection for R. padi parasitism reduced parasitism of Aphis glycines, the original host of A. rhamni. However, parasitism of R. padi did not increase from generation 2 to generation 3 of selection, suggesting reduced variance available for selection, which was indeed found. We tested the associations between 184 single nucleotide polymorphisms (SNP) and increased parasitism of R. padi and found 28 SNP loci, some of which were associated with increased and others with decreased parasitism of R. padi. We assembled and annotated the A. rhamni genome, mapped all SNP loci to contigs and tested whether genes on contigs with SNP loci associated with parasitism were enriched for candidate genes or gene functions. We identified 80 genes on these contigs that mapped to 1.2 Mb of the 483 Mb genome of A. rhamni but found little enrichment of candidate genes or gene functions.
Real-world evidence of axicabtagene ciloleucel (Axi-cel) for the treatment of large B-cell lymphoma (LBCL) in the United States (US).

7552 Background: Axi-cel is approved in the US for the treatment of adult patients with relapsed or refractory LBCL after 2 or more lines of systemic therapy. Post-market long term follow up study of commercial Axi-cel recipients using the Center for International Blood and Marrow Transplant Research was recently completed. Methods: From October 2017 to August 2020, 1,500 Axi-cel recipients from 79 centers were enrolled. Of these, 1001 patients with at least 6 months of follow-up were included in this analysis. Outcomes include complete and overall responses rates (CR and ORR), duration of response (DOR), progression-free and overall survival (PFS and OS), cytokine release syndrome (CRS) (Lee D 2014 and American Society for Transplantation and Cellular Therapy [ASTCT]), immune effector cell associated neurotoxicity syndrome (ICANS), hematologic recovery and subsequent neoplasm (SN). Subgroup analysis by sensitivity to therapy, defined as responsive to the last line of therapy prior to Axi-cel. Median follow-up was 12 months (range, 6-28 months). Results: The median age overall was 62 years, 37% were ≥ 65 years, 83% with Eastern Cooperative Oncology Group (ECOG) performance score 0-1, 28% with transformed lymphoma, 14% with high grade lymphoma, 29% with prior autologous transplant, and 66% with chemotherapy-resistant disease prior to Axi-cel. The median time from diagnosis to Axi-cel infusion was 15 months. Best ORR was 70% (CR 53%). Landmark analysis of patients in CR at 6 months post Axi-cel demonstrates a low number of subsequent progression/death events. With respect to outcomes for chemotherapy-sensitive disease versus resistant disease, the ORR, CR, 12-month PFS and OS were 78% vs. 66%, 60% vs. 48%, 55% (95% CI, 48-62%) vs. 40% (95% CI, 37-44%), and 70% (95% CI, 63-76%) vs. 54% (95% CI, 50-58%), respectively. CRS of any grade was reported in 83% of patients. Incidence of Grades ≥ 3 CRS was 10% according to Lee et al 2014, and 13% according to ASTCT Consensus Grading. Median time to any grade CRS was 4 days (range, 1-28 days), and 93% of CRS cases resolved with a median duration of 7 days (range, 1-121 days). ICANS were reported in 576 (57%) patients, grade >3 was 26%. The median time to onset of ICANS was 7 days (range, 1-82 days), and 86% resolved with a median duration of 9 days (range, 1 to 115 days). Twenty-nine patients (2.9%) reported SN: hematologic (N = 17), solid tumors (N = 12). Conclusions: This is the largest report on Axi-cel in the real-world setting and demonstrates consistent efficacy outcomes and further characterizes safety outcomes. Patients in CR at 6 months have sustained disease control with low number of relapse events. Although patients with therapy-sensitive disease experience better outcomes than patients with therapy-resistant, the overall outcomes on both groups of patients are favorable.
A climatology of trade-wind cumulus cold pools and their link to mesoscale cloud organization

Abstract. We present a climatology of trade cumulus cold pools and their associated meteorological perturbations based on more than ten years of in-situ and remote sensing data from the Barbados Cloud Observatory. Cold pools are identified by abrupt drops in surface temperature, and the mesoscale organization pattern is classified by a neural network algorithm based on GOES-16 ABI infrared images. We find cold pools to be ubiquitous in the winter trades – they are present about 7.8 % of the time and occur on 73 % of days. Cold pools with stronger temperature drops (∆T) are associated with deeper clouds, stronger precipitation, downdrafts and humidity drops, stronger wind gusts and updrafts at the onset of the front, and larger cloud cover compared to weaker cold pools. The downdraft strength together with the cold-pool front duration explains 50 % of the variability in ∆T. The mesoscale organization pattern has a strong influence on the occurrence frequency of cold pools. Fish has the largest cold-pool fraction (12.8 % of time), followed by Flowers and Gravel (9.9 % and 7.2 %), and lastly Sugar (1.6 %). Fish cold pools are also significantly stronger and longer-lasting compared to the other patterns, while Gravel cold pools are associated with significantly stronger updrafts and deeper cloud-top height maxima. The daily cycle of the occurrence frequency of Gravel, Flowers, and Fish can explain a large fraction of the daily cycle in the cold-pool occurrence, as well as the pronounced extension of the daily cycle of shallow convection into the early afternoon by cold pools. Overall, we find cold-pool periods to be ~90 % cloudier relative to the average winter trades. Also the wake of cold pools is characterized by above-average cloudiness, suggesting that mesoscale arcs enclosing broad clear-sky areas are an exception. A better understanding of how cold pools interact with and shape their environment could therefore be valuable to understand cloud cover variability in the trades.
Memory bias for social hierarchical information is modulated by perceived social rank

ABSTRACT Hierarchies pervade human society, characterising its members along diverse dimensions ranging from their abilities or skills in a particular domain to their economic status or physical stature. One intriguing aspect of the centrality of hierarchies, relative to egalitarian constructs, is that hierarchically-organised social information appears to be remembered more easily than non-hierarchically-organised information. However, it is not yet clear how one’s social rank within a hierarchy influences processing. In a pre-registered study with 66 healthy participants, we examined memory recall for hierarchical information when participants themselves were positioned higher in the hierarchy versus lower in the hierarchy, both relative to an egalitarian control condition. The results replicate previous work showing that hierarchical information is memorised faster relative to the egalitarian control. Importantly, this effect was modulated by the participant’s position within the hierarchy, with higher positioned participants memorising information faster than lower-positioned participants. This study provides new evidence showing biases in memory will favour hierarchical information if modulated by perceptions of one’s own social rank.
Effect of Silver Nano Particle Microalgae Chlorella pyrenoidosa and Dunaliella salina on Growth and Survival of Penaeus monodon Larvae

Penaeus monodon is one of the most important farmed crustaceans. Its also known as Asia Tiger Shrimp because its carapace and abdomen are transversely banded with red and white. The use of synthetic antibiotic in aquaculture had caused problems related to health and environmental safety. Chlorella pyrenoidosa and Dunaliella salina are photosynthetic microalgae. Silver nano particle in microalgae C. pyrenoidosa and D. salina had synthesized and showed their growth stability. They offer a potency to be exploited to supported growth and survival of shrimp larvae. The objective of the study was the application of silver nano particle in microalgae C. pyrenoidosa and D. salina on P. monodon larvae. The research methodology was carried out by making microalgae C. pyrenoidosa and D. salina containing silver nano particle and used as feed of shrimp larvae. Observations were made on the growth and survival of shrimp larvae compared to both microalgae and common feed. The results showed that the P. monodon larvae have the higher growth and survival rate with microalgae C. pyrenoidosa at the beginning of their growth compared to D. salina . However, microalgae without nanosilver and common feed showed a better result for growth and activity of shrimp larvae.
A Comparative Study on the Viscoelastic Properties of Wheat, Maize and Cassava Flours as Affected by Some Leguminous Seed Flours

The effects of some leguminous seed flour (LSF) on the viscoelastic properties of wheat, maize and cassava flours were investigated. The aim of the work was to evaluate the effect of the LSF on the pasting characteristics of the flours. There were significant differences in the proximate composition of the flours used in this study. Three LSF namely Brachystegia eurycoma, Detarium microcarpum, and Mucuna sloanei flours were used in this study. The LSF were added differently at 0 and 2% to wheat, maize and cassava flours on dry weight bases, the 0% addition served as the control. The viscoelastic properties were determined using Rapid Visco Analyser (RVA). The results showed that the LSF significantly affected the pasting properties of the wheat, maize and cassava flours. The LSF significantly increased (p>0.05) the breakdown, final, trough and peak viscosities of the wheat and maize flours. However, the LSF significantly (p>0.05) reduced the peak, breakdown and setback viscosities of cassava flour compared to the control.
Relationship between functional movement screen and physical performance in elite young soccer players

Backgroundː Soccer performance can be analyzed by different physical parameters such as linear speed and power. In addition, movement quality evaluations are used to assess individual functional capacity and a widely used tool is the functional movement screen (FMS). Objectives: The present study had three aims: 1) analyse the association of FMS final score and individual FMS scores with peak and relative muscle power and 10-m and 30-m sprints of young soccer players; 2) analyse the association between muscle power and speed from different categories controlled by FMS score; 3) compare peak and relative muscle power and 10-m and 30-m sprints between athletes with results of FMS >14 and < 14 scores in different categories. Methodsː Fifty-six Brazilian players from U15, U17, and U20 participated in the research. Subjects performed anthropometric measurements, FMS, muscle power, and 10-m, and 30-m sprint. Resultsː The results showed no association between FMS score and muscle power and speed (p > 0.05). However, stability-push-up showed small association with peak and relative muscle power (r = 0.28, p < 0.05; r = 0.29, p < 0.05, respectively). The in-line-lunge test showed inverse and small correlation with 10-m sprint (r = -0.28; p < 0.05). Relationship between peak and relative muscle power with 10-m and 30-m sprints showed moderate and small association in all categories, respectively (r = -0.76-0.32, p = 0.01). In addition, it was not found difference among players above and below 14 score. Conclusionː Based on these findings, the 14 score shows to be a weak cut-off value and it can be assumed that there are no association between FMS and power and speed in youth soccer.
Polysulfone/Vanillin Microcapsules for Antibacterial and Aromatic Finishing of Fabrics

Microencapsulation technology is being more and more applied in the textile industry because microcapsules can confer additional properties to conventional fabrics. In this context, polysulfone microcapsules containing vanillin were prepared, and their morphology, thermal stability, and antibacterial properties against Staphylococcus aureus were assessed. The microcapsules were fabricated onto 100% cotton fabrics by a coating technique. The resistance of the coating to several washing cycles was studied, and the durability of the aromatic finishing was determined. Capsules were stable in the range between 20 and 100 °C, and they inhibited the growth of the bacteria at 37 °C for, at least, one week. Most of the capsules added to the fabric were flushed away between the first and second washing cycle; however, some capsules were still observed after the fifth washing. Finally, a survey was conducted in order to know how consumers perceived the aroma, before and after several washings. Survey data was statis.
Relationship between Employee Engagement, Job Satisfaction and Potential Turnover

High employee engagement (EE) is associated with high work performance therefore; it is in the center of attention of researchers and HR managers. The aim of the study was to determine the level of employee engagement in the exposed workplace and to verify whether there are relationships between employee engagement, job satisfaction and potential labor turnout. Based on a survey conducted with operators (N=257) in call centers, where the rate of fluctuation is high, these relationships were confirmed. It was found that the level of EE may not be low even at a demanding workplace. It was also verified that EE has a positive effect on job satisfaction and at the same time negatively affects potential turnover.
Relevance of Traumatic Events and Routine Stressors at Work and PTSD Symptoms on Emergency Nurses

Emergency nurses are exposed daily to numerous stressful situations that can lead to the development of post-traumatic stress disorder (PTSD) symptoms. This study examined the relationship between traumatic events, routine stressors linked to trauma, and post-traumatic stress disorder (PTSD) symptoms in emergency nurses. For this purpose, a sample of 147 emergency nurses completed the Traumatic and Routine Stressors Scale on Emergency Nurses (TRSS-EN) and the Posttraumatic Diagnostic Scale (PDS-5). Results of correlations and moderate multiple regression analyses showed that the emotional impact of routine stressors was associated with a greater number of PTSD symptoms, and, apparently, to greater severity, in comparison to the emotional impact of traumatic events. Furthermore, the emotional impact of traumatic events acts as a moderator, changing the relationship between the emotional impact of routine stressors and PTSD symptoms, in the sense that the bigger the emotional impact of traumatic events, the bigger the relationship between the emotional impact of routine stressors and PTSD symptoms. These results suggest that the exposure to routine work-related stressors, in a context characterized by the presence of traumatic events may make emergency nurses particularly vulnerable to post-traumatic stress reactions. Some prevention measures are suggested according to the results of the study.
Reproductive biology of the bopyrid isopod Robinione overstreeti, a branchial parasite of the ghost shrimp Callichirus islagrande (Decapoda: Callichiridae) in the Gulf of Mexico

ABSTRACT Robinione overstreeti is a bopyrid isopod endemic to the Gulf of Mexico that inhabits the branchial chamber of the ghost shrimp Callichirus islagrande. Information on this host–parasite association is scant. This study describes population and reproductive features of R. overstreeti and its host. A total of 90 (9.97%) out of 903 individuals of C. islagrande collected from Tamiahua lagoon, Veracruz, Mexico, between April 2012 and October 2013, were parasitized by R. overstreeti. Parasite prevalence in male and female ghost shrimps was similar. However, no parasitized ovigerous females of C. islagrande were recorded, suggesting that R. overstreeti is a parasitic castrator. Host and parasite body sizes were positively correlated suggesting early host infestation by parasites and simultaneous growth of the host and parasite. Parasitic isopods frequently inhabited the same branchial chamber (n = 77) of ghost shrimps as adult male-female pairs. Females were occasionally found with supernumerary juveniles and cryptoniscus larvae in the same host individual, and rarely solitarily. Furthermore, the body size of paired adult male and female parasites was tightly correlated suggesting long-term ‘social’ monogamy in R. overstreeti. Fecundity in R. overstreeti varied between 1668 and 9884 embryos female−1 and increased with female body size.

FACTORS INFLUENCING TEACHERS’ INTENTIONS TO USE REALISTIC MATHEMATICS EDUCATION IN VIETNAM: AN EXTENSION OF THE THEORY OF PLANNED BEHAVIOR

Although Realistic Mathematics Education (RME) has become familiar to many mathematics teachers, we still have little understanding of the extent to which mathematics teachers are willing to employ RME rather than traditional teaching approaches. Based on the theory of planned behavior, in conjunction with some other factors, including facilitating conditions and perceived autonomy, this study investigated a model explaining the continued intention of mathematics teachers to use Realistic Mathematics Education. A structural equation model was used to access data from an online survey involving 500 secondary school mathematics teachers in Vietnam. The results revealed that while attitude, perceived behavioral control and perceived autonomy have positive significant impacts on intention to use RME, it appears that subjective norms and facilitating conditions do not. These findings are of significance to stakeholders, including policymakers, school managers, and mathematics teachers.
