Despite the importance of non-structural carbohydrates (NSC) for growth and survival in woody plants, we know little about whole-tree NSC storage. Here, Catalpa bungei trees fertilized using different schedules, including water and fertilizer integration, hole application, and no fertilization, were used to measure the spatial variations of sugar, starch, and NSC concentrations in the leaf, branch, stem, bark, and root. By calculating the volume of whole-tree NSC pools and the contribution of distinct organs, we were also able to compare the storage under various fertilization regimes. We found that the spatial distribution patterns of each organ undergoing different fertilization regimes were remarkably similar. Height-related increases in the sugar and NSC concentrations of the leaf and bark were observed. The concentrations of sugar and NSC in the branch did not appear to vary longitudinally or horizontally. The sugar and NSC concentrations in the stem fluctuated with height, first falling and then rising. The coarse root contained larger amounts of NSC components in comparison to fine root. Contrary to no fertilization, fertilization enhanced the distribution ratio of the leaf, branch, and stem NSC pools while decreasing the distribution ratio of the root NSC pool. Particularly, the addition of fertilizer and water significantly increased the biomass of the organs, enhancing the carbon sink of each organ and whole-tree in comparison to other fertilization regimes. Our main goal was to strengthen the empirical groundwork for comprehending the functional significance of NSC allocation and stock variations at the organ-level of C. bungei trees.

Aspergillus parasiticus (A. parasiticus) is known for producing aflatoxins and is a major threat to the food industry. Green synthesis of nanoparticles (NPs) is a cost-effective and environment-friendly approach. A variety of NPs have been explored as antifungal agents; however, their antifungal characteristics need to be further enhanced to compete with traditional fungicides. The present work describes the green synthesis of ZnO and CuO NPs by precipitation method using aqueous leaf extract of Manilkara zapota and their surface modification through polyaniline (PANI). Still, there is no published study on the application of PANI-coated particles as antifungal agents against A. parasiticus and hence was the focus of this work. The polymer-coated NPs were synthesized, characterized, and investigated for their antifungal properties against A. parasiticus. Textural and structural characterization of PANI-coated and non-coated ZnO and CuO NPs were confirmed through FT-IR, SEM, and XRD techniques. The PANI-coated NPs presented higher fungal growth inhibition (%) as compared to the non-coated ones. The maximum inhibition of 77 ± 2% (n = 3) was shown by PANI/ZnO NPs at a concentration of 12 mmol L−1 and 72 h of incubation. The non-coated NPs presented a lower inhibition rate with respect to their coated NPs, thus justifying the role of polymeric coating in improving antifungal efficiency.
Full-length chloroplast genome of Dongxiang wild rice reveals small single-copy region switching
Authors: Liang Jianguang , Chen Rui , Zhang Fantao , Wang Qian , Yang Yingxia , Lv Mingjie , Yan Shuangyong , Gao Shan
Published: September 2022

Background

Plant chloroplast DNA (cpDNA) typically has a circular structure, including a large single-copy region (LSC), a small single-copy region (SSC) and two inverted repeats (IR1 and IR2). The organization of these four elementary regions LSC-IR1-SSC-IR2 is highly conserved across all plant cpDNAs. Very few structural variations (SVs) occurring at the elementary-region level have been reported.

Results

In the present study, we assembled the full-length cpDNA of Dongxiang wild rice line 159 (DXWR159). Using the long PacBio subreads, we discovered a large inversion of SSC and a large duplication of IR in DXWR159 cpDNAs. Significantly, we reported for the first time forward and reverse SSCs of cpDNAs in similar proportions and named the frequent inversion of a whole SSC as SSC switching.

Conclusions

Our study helps researchers to correctly assemble the chloroplast genomes. Our recombination model explained the formation of large SVs in cpDNAs and provided insights into a novel scientific question that if there are common mechanisms in the formation or translocation of all kinds of transposon-like elements (TLEs). We propose that: (1) large inversion is the most accepted mutation type of SVs in cpDNAs; (2) SSC switching ubiquitous occurs in plant cpDNAs; and (3) further investigation of molecular mechanism underlying SSC switching may reveal new driving forces for large SVs.

Authors: Lou Mingzhao , Lu Jinke , Wang Le , Jiang Huanyu , Zhou Mingchuan
Published: September 2022

The plant factory is a form of controlled environment agriculture (CEA) which is offers a promising solution to the problem of food security worldwide. Plant growth parameters need to be acquired for process control and yield estimation in plant factories. In this paper, we propose a fast and non-destructive framework for extracting growth parameters. Firstly, ToF camera (Microsoft Kinect V2) is used to obtain the point cloud from the top view, and then the lettuce point cloud is separated. According to the growth characteristics of lettuce, a geometric method is proposed to complete the incomplete lettuce point cloud. The treated point cloud has a high linear correlation with the actual plant height (R2 = 0.961), leaf area (R2 = 0.964), and fresh weight (R2 = 0.911) with a significant improvement compared to untreated point cloud. The result suggests our proposed point cloud completion method have has the potential to tackle the problem of obtaining the plant growth parameters from a single 3D view with occlusion.

Published: September 2022

Nelumbo nucifera (N. nucifera) is an important aquatic economic crop with high edible, medicinal, ornamental, and ecological restoration values. Aerenchyma formation in N. nucifera root is an adaptive trait to the aquatic environment in long-term evolution. In this study, light microscopy, electron microscopy, and molecular biology techniques were used to study the process of the aerenchyma development and cytological events in N. nucifera root and the dynamic changes of aerenchyma formation under the treatment of exogenous 21% oxygen, ethylene (ET), and ET synthesis i + nhibitor 1-methylcyclopropene (1-MCP). The results showed that programmed cell death (PCD) occurred during the aerenchyma formation in N. nucifera root. Plasmalemma invagination and vacuole membrane rupture appeared in the formation stage, followed by nuclear deformation, chromatin condensation and marginalization, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) detection was positive at this time. In the expansion stage of the aerenchyma development, cytoplasmic degradation and many vesicles appeared in the cytoplasm, and organelles began to degrade. Then the plasma membrane began to degrade, and the degradation of the cell wall was the last PCD step. After 21% oxygen was continuously filled in the rhizosphere environment of N. nucifera roots, the area of aerenchyma in N. nucifera roots was smaller than that in the control group. Moreover, ET induced the earlier occurrence of aerenchyma in N. nucifera root, but also, the area of aerenchyma became larger than that of the control. On the contrary, 1-MCP inhibited the occurrence of aerenchyma to some extent. Therefore, the formation of aerenchyma in N. nucifera root resulted from PCD, and its formation mode was schizo-lysigenous. A hypoxic environment could induce aerenchyma formation in plants. ET signal was involved in aerenchyma formation in N. nucifera root and had a positive regulatory effect. This study provides relevant data on the formation mechanism of plant aerenchyma and the cytological basis for exploring the regulation mechanism of plant aerenchyma formation.
Lipid turnover and SQUAMOSA promoter-binding proteins mediate variation in fatty acid desaturation under early nitrogen deprivation revealed by lipidomic and transcriptomic analyses in Chlorella pyrenoidosa
Authors: Wang Rui , Miao Xiaoling
Published: September 2022

Nitrogen deprivation induces variations in fatty acid desaturation in microalgae, which determines the performance of biodiesel and the nutritional value of bioproducts. However, the detailed scenario and the underlying regulatory mechanism remain unclear. In this study, we attempt to outline these scenario and mechanisms by performing biochemical, lipidomic, and transcriptomic analyses in Chlorella pyrenoidosa and functional characterization of transcription factors in Yarrowia lipolytica. We found that early nitrogen deprivation dramatically reduced fatty acid desaturation without increasing lipid content. The contents of palmitic acid (16:0) and oleic acid (18:1) dramatically increased to 2.14 and 2.87 times that of nitrogen repletion on the second day, respectively. Lipidomic analysis showed the transfer of polyunsaturated fatty acids from phospholipids and glycolipids to triacylglycerols, and an increase in lipid species with 16:0 or 18:1 under nitrogen deprivation conditions. Upregulated stearoyl-ACP desaturase and oleyl-ACP thioesterase promoted the synthesis of 18:1, but restricted acetyl-CoA supply revealed that it was the intensive lipid turnover instead of an attenuated Kennedy pathway that played an important role in the variation in fatty acid composition under early nitrogen deprivation. Finally, two differentially expressed SQUAMOSA promoter-binding proteins (SBPs) were heterologously expressed in Y. lipolytica, demonstrating their role in promoting the accumulation of total fatty acid and the reduction in fatty acid desaturation. These results revealed the crucial role of lipid turnover and SBPs in determining fatty acid desaturation under early nitrogen deprivation, opening new avenues for the metabolic engineering of fatty acid desaturation in microalgae.

Published: September 2022

Owing to the COVID-19 pandemic, working from home promotes the importance of indoor environment qualities. With the settings and functions of home offices, an experiment was carried out to determine the interaction effects between indoor plants and traffic noise levels (TNLs) on the performance and environmental evaluations of English reading comprehension tasks (ERCTs) and the performance of short-term breaks. A sample of 22 Chinese university students (12 males and 10 females) took part in the experiment. Two visual conditions (with and without plants) and five TNLs (i.e., 35, 45, 50, 55, and 60 dBA TNL) were included. Participants’ accuracy rates, eye movements, mental workload, and feelings about the environment were collected. The mental fatigue recovery (MFR), visual fatigue recovery (VFR), anxiety recovery (AR), and unfriendly recovery (UR) were measured for the analysis of a 5-min short-term break. The results demonstrate (1) plants have significant effects on ERCTs and short-term breaks, especially at 45 and 50 dBA TNL; (2) the effects of TNLs on ERCTs’ eye movements and work environment satisfaction differ by the presence of plants, e.g., the average pupil diameter (APD), lighting and layout satisfaction; (3) The effects of indoor plants on ERCT differ by the range of TNLs. In conclusion, indoor plants are beneficial to home workers engaged in ERCT when TNL does not exceed 50 dBA. The current data highlight the importance of audio-visual interaction in home offices and provide insights into the interaction mechanism between indoor plants and traffic noise.

Published: September 2022

It is deemed that the effectiveness of teachers is highly entangled with psycho-emotional constructs, such as critical thinking (CT), emotion regulation (ER), and immunity. Despite the potential roles of CR, ER, and immunity, their possible relationships have remained unexplored in the higher education context of Iran. To fill in this lacuna, this study explored the potential role of CT and ER in university teachers' immunity in the Iranian higher education context. For this purpose, a total of 293 English university teachers were selected using a convenience sampling method. They were invited to fill out the Watson–Glaser Critical Thinking Appraisal-Form, Language Teacher Emotion Regulation Inventory, and Language Teacher Immunity Instrument. The findings of path analysis indicated that the university teachers with higher CT were more productively immunized. Moreover, the results revealed that ER could predict the university teachers' immunity. The findings of the study lead to this implication that higher order thinking skills, emotion regulatory strategies, and immune enhancement should be incorporated into educational programs of higher education.
The quality enhancement of action research on primary school English instruction in Chinese rural areas: An analysis based on multimodality
Authors: Zhang Haiyan , Han Cunxin , Ma Hongyan , Wang Liusheng
Published: September 2022

This study investigates the influences of action research on primary school English instruction from five dimensions in the classroom, viz., types of questions, language errors, gestures, facial expressions, and interpersonal distance. Four English teachers’ 9 real classroom teaching videos before and after action research are collected and annotated by using ELAN software. The results show that primary school English teachers in Chinese rural areas prefer closed questions to open questions; They make some language errors; Deictic gestures are the most common gestures used, while metaphoric gestures, beat gestures and iconic gestures are rare; Teachers have the same preference for three types of facial expressions, and teachers’ serious expressions accounts for most of the time; They seldom keep an intimate distance or personal distance from their students. Second, Action research is effective to motivate teachers in rural areas, who make great progress in all five dimensions after AR: more open questions are asked; pragmatic errors and grammatical errors are reduced; deictic gestures increase; apathetic decrease, and more intimate distance is exhibited in the interpersonal distance dimension. Third, teacher’s English teaching competence is partly transferrable to her future professional development, and this is also the long-lasting effect of AR.

Authors: Prokopczyk Adam , Wochyński Zbigniew
Published: September 2022

Objectives

The aim of the pilot study was to check the influence of the training process on the Special Aviation Gymnastics Instruments (SAGI) on the improvement of the psychomotor skills, expressed as an increase in the percentage of ability to perform all tasks and the number of reels on a loop.

Materials and methods

Cadets - second year pilots (n = 20), male, mean age 20.8 years old, studying at the faculty of a pilot. Cadets were carrying out a 40-h special pilot training program on SAGI. They were subjected to two exercise tests (reels forward on looping), before and after the period of special training. Exercise tests were performed with the use of a diagnostic and training device used to assess psychomotor skills. During two tests, heart rate (HR) and blood pressure were measured. The obtained results were analysed statistically.

Results

There was a statistically significant increase in the percentage of ability to perform all tasks (p < 0.01) and a statistically insignificant increase in the number of reels forward on looping, in test II in relation to test I. A significant increase was found in the correct execution of arithmetic operations (p < 0.05) in test II in relation to test I. In the remaining tests, an increase in results in test II was noted, but it was not statistically significant. There was a significant correlation between the percentage ability to perform all tasks and the number of completed reels in test I (p < 0.05) and insignificant in test II. In test II, a statistically insignificant higher level of heart rate and blood pressure before and after the effort was noted, compared to test I.

Conclusion

It was found that the training process on SAGI increased the psychomotority level by increasing the percentage of ability to perform all tasks and the number of reels, in test II in relation to test I.
Preference of harmonic loudness degree on piano timbre
Authors: Cai Yuxiang , Ling Yushi , Cao Guikang , Zhou Xuefeng
Published: September 2022

This study exploratively conducted two investigations of timbre influenced by harmonic loudness. Investigation 1 examined piano timbre preference between non-processed melodies and two kinds of adjustments created via an equalizer–a basic tool used for sound engineering and for producing audio materials. Using the paired comparison method, 98 respondents were surveyed. The results show that in the bass range of the piano sound, the preferred audio material was that produced via an equalizer by reducing the loudness of the 7th and 9th harmonics by 15 dB, while enhancing the loudness of the 8th harmonic by 15 dB. Investigation 2 examined three degrees of the processed melodies—adjusting the harmonics by 15, 10, and 5 dB. The results show that the 15 dB change was the best, while the 10 dB change was the worst. These results provide a new approach to improving the sound timbre for sound engineering and artificial intelligence music production.

Published: September 2022

Posttraumatic growth (PTG) has been correlated with coping style among patients with breast cancer. However, to date, there is no consensus on the extent to which coping style is associated with PTG in patients with breast cancer. Therefore, we performed a meta-analysis to quantitatively synthesize previous findings. Based on the PRISMA method, this study employed a random effects model using the Stata software (version 16.0) to calculate the pooled correlation coefficient and examined a range of moderators: cancer stage, publication type, participants’ age, and coping style measurement tools. Relevant studies, published from inception to 9 March 2022, were identified through a systematic search in PubMed, Embase, Web of Science, PsycINFO, WANFANG DATA, Chinese National Knowledge Infrastructure (CNKI), and China Science and Technology Journal Database (VIP) databases. Finally, 20 studies involving 3,571 breast cancer patients were included in this investigation. The results showed a high positive relation between confrontation coping and PTG and a moderate positive relation between avoidance coping and PTG (confrontation: r = 0.456; avoidance: r = 0.291). Additionally, a moderate negative relation was identified between acceptance–resignation coping and PTG (r = –0.289). Publication type and coping style measurement tools moderated the relation between coping style and PTG among breast cancer patients. The findings indicated that breast cancer patients should either confront the disease or avoid coping with it according to their disease state, which would facilitate better growth. More studies, especially, large prospective studies, are warranted to verify our findings.

Visual performance of painting colors based on psychological factors
Authors: Yao Chenchen , Tian Tian , Gao Cai , Zhao Shuangping , Liu Qingyan
Published: September 2022

Humans have been exploring colors since ancient times, but relatively complete color systems appeared one after another in the twentieth century. Even without language and other information exchanges, colors can still convey information and stimulate emotions. Therefore, color can have both physical and psychological effects on people. In this context, this paper studies the visual representation of painting colors based on psychological factors. The article studies the theory of personality traits and introduces the related content of visual psychology. To explore the relationship between each variable and color psychology and the visual representation of painting colors, a binary logistic regression analysis is performed. The colors in the post-impressionist paintings of Van Gogh and Gauguin is contrasted, and experiments on psychological factors and color research is conducted. The factors that affect the color tone of the picture and the influence of psychological factors on the judgment of color brightness are investigated. Finally, the correlation analysis of personality trait dimension and irrational behavior is carried out. The experimental results of the article show that after the analysis of variance, the significance levels of regression model 1 and model 2 both reach 0.000, and the adjusted R squares are 0.319 and 0.356, respectively. In this study, regression model 2 was selected as the final model. According to Model 2, the standardized regression coefficients of agreeableness and neuroticism are 0.438 and -0.251, respectively, and the significance of the regression coefficients are 0.000 and 0.021, respectively. The research on the visual performance of painting colors based on psychological factors has been well completed.
One uncertainty added on top of another: Challenges and resources of mothers of preterm infants during the COVID-19 pandemic
Authors: Shoshi Palmor Haspel , Tuval-Mashiach Rivka , Bin Nun Alona
Published: September 2022

Aims and objectives

To qualitatively explore COVID-19-related experiences of mothers of preterm infants in the Neonatal Intensive Care Unit (NICU), the main challenges they face, and the resources available for them.

Background

The birth of a preterm infant is a stressful event under otherwise normal circumstances. The outbreak of COVID-19, the uncertainty about the virus and how it spreads, and the restrictions imposed, may have exacerbated the stress of caring for a preterm infant.

Design

Retrospective interviews.

Methods

In-depth interviews with 12 mothers of preterm infants who were hospitalized in the NICU at the time of study. The interview addressed challenges and resources related to coping with the pandemic. The interviews were transcribed and content analyzed, based on Lieblich et al’s model for narrative analysis. This research was conducted in accordance with the COREQ checklist.

Results

The overarching experience shared by all mothers was accumulative stress caused by a combination of factors related to the infant’s health and COVID-19-related stressors. A central theme was the dissonance between the mothers’ expectations from the birth and infant, and the reality they encountered. Other themes included fear of infecting the infant, loneliness, and stress caused by the restrictions that disrupted daily routines. Resources included a sense of shared fate regarding the pandemic, improvements in the infant’s condition, religious faith, emotional support from the partner, and support from professional staff.

Conclusion

Caring for a preterm infant during a pandemic is a challenging experience on many levels. The loss of significant support resources puts mothers of these infants at a higher risk for psychological distress.

Relevance to clinical practice

Awareness of mothers’ accumulative stress due to the COVID-19 pandemic may assist the staff in developing procedures that can alleviate parental stress, for example by enabling mothers to connect to each other, giving clear information to compensate for physical and social distancing and providing professional mental health support.
Why does subordinates’ negative workplace gossip lead to supervisor undermining? A moderated mediation model
Authors: Zeng Hao , Zhao Lijing , Li Jinsheng
Published: September 2022

Objectives

Previous studies on negative workplace gossip have neglected the role of gossip targets of supervisors. The purpose of this paper is to deepen our understanding of how subordinates’ negative workplace gossip affects supervisors’ work-related behaviors. Drawing upon conservation of resource theory, the authors propose that subordinates’ negative gossip leads to supervisor emotional exhaustion. In turn, such emotional exhaustion provokes supervisors to exhibit undermining toward their subordinates. Additionally, the authors propose that a trait factor, namely, supervisor mindfulness, mitigates the relationship between such negative workplace gossip and supervisors’ emotional exhaustion.

Method

Data were collected from employees (e.g., subordinates) and their immediate supervisors in 35 organizations located in Jiangsu and Anhui Provinces in China. The data were obtained at three time points, each time interval was 2 weeks, and finally, 362 valid data points were obtained.

Results

The following findings were obtained: (1) perceived subordinates’ negative gossip has a significant positive effect on supervisor undermining; (2) supervisor emotional exhaustion mediates the relationship between perceived subordinates’ negative gossip and supervisor undermining; and (3) supervisor mindfulness moderates the relationship between perceived subordinates’ negative gossip and supervisor emotional exhaustion and moderates the mediating effect of supervisor emotional exhaustion on the relationship between perceived subordinates’ negative gossip and supervisor undermining.

Conclusion

Using multisource data and a moderated mediation model, we found that subordinates’ negative workplace gossip predicts supervisor undermining through supervisor emotional exhaustion. We also discovered that supervisor mindfulness can buffer the positive relationship between perceived subordinates’ negative workplace gossip and supervisor undermining. These findings have important implications for the literature on negative gossip in the workforce, especially the impact of subordinates’ negative workplace gossip on supervisors’ responses.

Published: September 2022

The higher education sector was affected by this pandemic, managing enduring challenges since early 2020. Institutions of higher learning (IHL) are prepared to address unsurmountable challenges to ensure that students are not deceived and are being given the proper nurture, coupled with adherence to syllabuses. Simultaneously, the COVID-19 pandemic has caused unscrupulous pressure on students of these institutions. The psychological waves are creating mammoth consequences, affecting the beneficiaries of the higher education system and their families. In recent years, with limited studies on psychological impact among tertiary students on a cross-country basis, general self-efficacy, and the degree of coping strategies, we were motivated to investigate the degree of depression, anxiety, and stress (DAS), among this cohort of students encompassing the pre-university/Diploma, 1st–4th-year undergraduate, and postgraduate students from private universities in Malaysia, Indonesia, India, Southern Africa, and China, representing the emerging economies. A cross-sectional survey was conducted, followed by quantitative analysis. The objective of this study was to recognize whether there is a relationship between the psychological impact of DAS and the coping strategies adopted by the undergraduate students responding during the lockdown. The findings of this study revealed that with a sample size of 397, DAS lacked any severe impact on students across gender, country, household income, and level of education. DAS was established to be well managed with a coping strategy and self-efficacy established. This study resulted in a deeper understanding of DAS among undergraduates in emerging economies and their degree of coping behavior, providing a glimpse of the approach of millennials to handle DAS during the pandemic.
Similar but different: High prevalence of synesthesia in autonomous sensory meridian response (ASMR)
Authors: Poerio Giulia L. , Ueda Manami , Kondo Hirohito M.
Published: September 2022

Autonomous sensory meridian response (ASMR) is a complex sensory-emotional experience characterized by pleasant tingling sensations initiating at the scalp. ASMR is triggered in some people (called ASMR-responders) by stimuli including whispering, personal attention, and crisp sounds (termed ASMR triggers). Since its inception, ASMR has been likened to synesthesia, but convincing empirical data directly linking ASMR with synesthesia is lacking. In this study, we examined whether the prevalence of synesthesia is indeed significantly higher in ASMR-responders than non-responders. A sample of working adults and students (N = 648) were surveyed about their experience with ASMR and common types of synesthesia. The proportion of synesthetes who were classified as ASMR-responders was 52%, whereas 22% of ASMR-responders were also synesthetes. These results suggest that: (1) over half of those identifying as synesthetes also experience ASMR, and (2) that synesthesia is up to four times as common among ASMR-responders as among non-responders (22% vs. 5%). Findings also suggest a prevalence rate for ASMR of approximately 20%. Overall, the co-occurrence of ASMR and synesthesia lends empirical support to the idea that ASMR may be driven by synesthetic mechanisms, but future research would benefit from examining how ASMR and synesthesia are different, as well as similar.
Dialects, motivation, and English proficiency: Empirical evidence from China
Authors: Marjerison Rob Kim , Yang Shuo
Published: September 2022

Within the context of China, this study seeks to examine the relationship between English language proficiency, the native dialect of the learner, and the learner’s reason, or motivation for learning English. English language proficiency can be an important vehicle for accessing high quality higher education, for interacting with non-Chinese, and for enhancing employment and career opportunities Data was gathered through an online survey with 985 usable responses recorded. Respondents included a distribution of speakers from five of the major distinct dialects of China. The analysis provides empirical evidence of a diversity of propensities and motivations for English language acquisition among learners from different regions and native dialects. Access to international higher education as a type of motivation is found to have a moderating effect on English proficiency. Other findings suggest that learners in regions with more historic exposure to foreign interaction are more likely to be motivated for social reasons, those from regions with export focused commerce will be motivated for business related reasons. The results of this study may be of interest to policy makers, linguists, educators, and those with an interest in socioeconomic sustainability through language acquisition and education as a method of socioeconomic mobility.
Boosting EFL learners’ commitment and enjoyment in language learning through social networking: A literature review
Authors: Li Bing
Published: September 2022

Social networking applications have been designed as innovative technologies used by the higher education section to enhance the acquisition of literacy skills, driving learners to engage in online learning platforms. Such tools such as social networking have also been proven to facilitate teaching and learning; therefore, educational programs and universities are increasingly making use of networking sites to form connections with students and to offer online instructional content. This trend has placed questions, regarding the effect of social media on language learning and its potential use as an effective instructional tool. The constructive role of enjoyment did not obtain equal academic consideration in the EFL learning milieu until Positive Psychology was presented to L2 education. Using social networking, users find online tasks appealing and experience the enjoyment that, in turn, impacts their behavioral intention to use them positively. Commitment is another factor that refers to the degree to which students are involved in learning enthusiastically. This construct concerns the extent to which students are loyal to learning, textbooks, and class etiquette. As it contributes to the quality of learning, it is considered a prerequisite for students’ academic success and educational attainment. Based on the role of the above-mentioned constructs in language learning, the present review tries to consider the role of social networking in boosting EFL students’ commitment and enjoyment. Consequently, some implications are presented for academic stakeholders in the quest of considering the role of social networking in language education.

Authors: Kamarulbahri Tengku Mohd Saifuddin Tengku , Ariaratnam Suthahar , Nikmat Azlina Wati , Abdullah Nik Nairan , Khing Tan Lee
Published: September 2022

Background

It is essential for caregivers of schizophrenia patients to have effective coping mechanisms to deal with their own mental health. However, research on the factors that contribute to the coping mechanisms of caregivers is limited. The purpose of this study is to investigate the use of coping strategies and their correlations to socio-demographic features, psychological distress, and social support among the caregivers of patients with schizophrenia.

Method

Through the convenience sampling method, 331 caregivers of patients with schizophrenia participated in this cross-sectional study. The respondents comprised caregivers who had attended an outpatient psychiatric clinic, providing the socio-demographic data. The study involves three instruments: the Kessler's Psychological Distress (K10); the Multidimensional Scale of Perceived Social Support (MSPSS); and the Brief-COPE.

Findings

Using multivariable analysis, psychological distress was identified as a substantial independent predictor of emotion-focused, problem-focused, and avoidance coping strategies. Good social support was linked to the usage of problem-focused and emotion-focused coping strategies.

Conclusion

It has been demonstrated that good social support and psychological distress are associated with coping strategies. More prospective and qualitative research is required to determine how coping strategies will be able to assist Malaysian caregivers to develop a more holistic approach to treating patients with schizophrenia.
An empirical study of the effect of a flooding event caused by extreme rainfall on preventive behaviors against COVID-19
Authors: Liu Chengcheng , Lu Qibin , Zhang Qiang
Published: September 2022

Since the outbreak of COVID-19, wearing masks, vaccinations, and maintaining a safe distance has become social behaviors advocated by the government and widely adopted by the public. At the same time, unpredictable natural disaster risks brought by extreme climate change compound difficulties during epidemics and cause systemic risks that influence the existing pattern of epidemic prevention. Therefore, it is necessary to explore the effect of natural disaster risk caused by climate change on the response to outbreaks in the context of the COVID-19 epidemic. This study will focus on individual-level epidemic prevention behaviors, taking as an example the significant risk of severe destructive flooding caused by heavy rains in Henan, China, on July 20, 2021, which claimed 398 lives, to explore the effect of floods on the preventive behaviors of residents in the hardest hit areas against COVID-19. Through the multi-stage stratified random sampling of the affected residents in Zhengzhou, Xinxiang, Hebi, Luoyang, Anyang, and other cities in Henan Province, 2,744 affected people were surveyed via questionnaires. Through the linear regression model and moderating effect analysis, the study found that after floods, the individual's flood risk perception and response behaviors significantly correlated with the individual's prevention behaviors against COVID-19. Specifically, both flood risk perception and response behaviors strengthened the individual's prevention behaviors. Furthermore, the study also found that community risk preparation behavior and social capital can moderate the above relationship to a certain extent. The research can guide risk communication under the compound risk scenario and prevent risky public behavior under the consistent presence of COVID-19 in the community.

Authors: Pei Yuanyuan , Guo Yi , Wu Tong , Liang Huiying
Published: September 2022

The dynamic transmission of asymptomatic and symptomatic COVID-19 infections is difficult to quantify because asymptomatic infections are not readily recognized or self-identified. To address this issue, we collected data on asymptomatic and symptomatic infections from four Chinese regions (Beijing, Dalian, Xinjiang, and Guangzhou). These data were considered reliable because the government had implemented large-scale multiple testing during the outbreak in the four regions. We modified the classical susceptible–exposure–infection–recovery model and combined it with mathematical tools to quantitatively analyze the number of infections caused by asymptomatic and symptomatic infections during dynamic transmission, respectively. The results indicated that the ratios of the total number of asymptomatic to symptomatic infections were 0.13:1, 0.48:1, 0.29:1, and 0.15:1, respectively, in the four regions. However, the ratio of the total number of infections caused by asymptomatic and symptomatic infections were 4.64:1, 6.21:1, 1.49:1, and 1.76:1, respectively. Furthermore, the present study describes the daily number of healthy people infected by symptomatic and asymptomatic transmission and the dynamic transmission process. Although there were fewer asymptomatic infections in the four aforementioned regions, their infectivity was found to be significantly higher, implying a greater need for timely screening and control of infections, particularly asymptomatic ones, to contain the spread of COVID-19.

Objective

Cognitive function is essential in ensuring the quality of life of the elderly. This study aimed to investigate the effects of Baduanjin imagery and Baduanjin movement (a traditional Chinese health exercise, TCHE) on cognitive function in the elderly using functional near-infrared spectroscopy (fNIRS).

Methods

72 participants with a mean age of 66.92 years (SD = 4.77) were recruited for this study. The participants were randomly assigned to three groups: the Baduanjin imagery, the Baduanjin exercise, and the Control. Stroop task was used to record the accuracy and reaction times, and a near-infrared spectral brain imaging system was used to monitor the brain's oxy-hemoglobin concentration responses.

Results

(1) For the reaction times of Stroop incongruent tasks, the main effect of the test phase (F = 114.076, p < 0.001) and the interaction effect between test phase and group (F = 10.533, p < 0.001) were all significant. The simple effect analysis further demonstrated that the reaction times of the Baduanjin imagery group and Baduanjin exercise group in the post-test was faster than that in the pre-test (ps < 0.001); (2) Analysis of fNIRS data showed the significant interaction effect (F = 2.554, p = 0.013) between the test phase and group in the left dorsolateral prefrontal cortex. Further analysis showed that, during the post-test incongruent tasks, the oxy-Hb variations were significantly higher in participants of the Baduanjin imagery group (p = 0.005) and Baduanjin exercise group (p = 0.002) than in the control group; For the right inferior frontal gyrus, the interaction between the test phase and group was significant (F = 2.060, p = 0.044). Further analysis showed that, during the post-test incongruent tasks, the oxy-Hb variations were significantly higher in participants of the Baduanjin imagery group than in the control group (p = 0.001).

Conclusion

Baduanjin imagery and exercise positively affect cognitive performance; Baduanjin imagery and exercise activated the left dorsolateral prefrontal cortex; Baduanjin imagery activated the right inferior frontal gyrus, while Baduanjin exercise could not.
Determinants of emotional distress in neonatal healthcare professionals: An exploratory analysis

Published: September 2022

Background

High levels of mental health problems have been consistently reported among neonatal healthcare professionals. While studies suggest that personality, coping strategies and safety culture might contribute to the psychological wellbeing of healthcare professionals, they have not been systematically investigated in low-risk (i.e., neonatal wards; NWs) and high-risk (i.e., neonatal intensive care units; NICUs) neonatal contexts. The current study investigated potential predictors of professionals' emotional distress and whether they differ according to the work setting (i.e., NICUs vs. NWs).

Methods

Healthcare professionals (N = 314) from 7 level-3 (i.e., NICUs) and 6 level-2 (i.e., NWs) neonatal units in Tuscany were included. Emotional distress (i.e., anxiety, depression, psychosomatic, post-traumatic stress symptoms and emotional exhaustion), Behavioral Inhibition System (BIS) and Behavioral Approach System (BAS) sensitivity, coping strategies and safety culture were assessed through well-validated, self-reported questionnaires.

Results

Greater BIS/BAS sensitivity, avoidance coping strategies and a sub-dimension of safety culture (i.e., stress recognition) were significantly associated with greater risk of emotional distress, whereas job satisfaction emerged as a protective factor. Three specific profiles of professionals in term of personality, coping and safety culture were identified and further predicted emotional distress. Neonatal wards and NICUs personnel presented different associations between personality, coping and safety culture.

Conclusion

These findings highlighted significant modifiable contributors of neonatal mental healthcare professionals' wellbeing. Institutional initiatives that target these factors and, particularly, job satisfaction may promote professionals' emotional wellbeing and thus improve caring processes.
Volunteering in the front line of the Ukrainian refugee crisis: A brief report from Poland

Published: September 2022

This study aims to analyse the experiences and motivations of volunteers who supported Ukrainian refugees who fled to Poland. Our study was conducted among 196 volunteers in Poznan, Poland who answered questions regarding their experiences with voluntary service during the current refugee crisis and the reasons they became involved in volunteer efforts. We found that although the Polish state had no prior experience in welcoming refugees on a mass scale, the Russo-Ukrainian War has resulted in the emergence of “spontaneous volunteers” who have offered their help and assistance to the flood of refugees sweeping in from its eastern neighbor. We also found that because many Polish citizens believe that helping those in need should not rest solely on the government there are two main motivations to volunteer: a general willingness to help and the willingness to volunteer on behalf of Ukrainian refugees. Finally, while this study highlights that in times of crisis, most people are primarily motivated by humanistic and democratic values, including altruism and public service, emotions also play an important role in influencing people's decision to engage in voluntary service.
