ObjectivesTo translate and revise the Contraceptive Knowledge Assessment (CKA) scale and apply it to Chinese college male/female students. After cross-cultural adjustment of the source scale, the reliability and validity of the Chinese version of the scale were tested.Study designThis study utilized a cross-sectional research design. Translation, cognitive interviews and a psychometric evaluation were carried out. A survey was then conducted among 388 college students in Shanghai to test the reliability and validity of the Chinese version of the CKA scale.ResultsThere were 22 items in the Chinese version. Factor analysis extracted 8 common factors, with a cumulative contribution rate of 58.923%, and 3 items were eliminated. The Cronbach’s α coefficient was 0.793, and the test-retest reliability Pearson correlation coefficient was 0.743.ConclusionThe Chinese version of the CKA scale has good reliability and validity and is suitable for assessing the level of contraceptive knowledge.

Implementation of Basketball Education Program Affecting the Personal Development of College Students in Shanghai, China

The study examined the implementation of a basketball education program and its impact on students' skills acquisition, personal development, and educational achievements. The results revealed that the program was moderately implemented across key areas such as coaching/instructional approach, skills training, personal development, and student engagement. While the program proved effective in fostering basketball-related skills acquisition, it showed weaker correlations with students' academic achievements and personal development. A positive relationship was identified between the coaching approach and skills acquisition, suggesting that structured coaching enhances students' technical abilities. However, the program demonstrated a negative correlation between coaching and academic performance, indicating that students may prioritize athletic success over educational growth. Additionally, the findings indicated that other aspects of the program, such as personal development and skills training, had no significant impact on students' broader personal growth or academic achievements. Overall, while the program successfully supports athletic growth, it requires further refinement to enhance its influence on students' educational outcomes and holistic development. The integration of academic support and a stronger focus on personal development could ensure a more balanced approach to fostering student success both on and off the court.

Genome-wide profiling of long non-coding RNA following ozone exposure: A randomized, controlled exposure trial

BackgroundExposure to ambient ozone has been associated with extrapulmonary health, but the underlying mechanisms remain to be understood. LncRNAs are involved in the regulation of gene expression, but their regulatory mechanisms in ozone-related health effects are scarcely explored. ObjectiveTo investigate genome-wide lncRNA changes after short-term ozone exposure and their regulatory roles in ozone exposure and gene expression. MethodWe conducted a randomized, crossover, controlled exposure trial in 32 healthy college students in Shanghai, China. Each participant received both 200-ppb ozone exposure and filtered air exposure for 2 h in a random order with a 14-day washout period. Blood samples were collected after each exposure and used for lncRNA sequencing. Differentially expressed lncRNAs between the two exposures were identified using orthogonal partial least squares discriminant analysis and linear regression analysis. LncRNAs-targeted mRNAs were mapped and subjected to enrichment analyses. We also constructed lncRNA-miRNA-mRNA networks. ResultsA total of 90 lncRNAs were differentially expressed after exposure to ozone, with 49 up-regulated and 41 down-regulated. Enrichment analyses suggested that these dysregulated lncRNAs were involved in a variety of biological processes, including those related to oxidative stress, inflammation response, and cell proliferation, development, and differentiation. Multiple pathways such as IL-17 signaling, NF-kB signaling, and Rho GTPases signaling were also enriched. Furthermore, the lncRNA-miRNA-mRNA network revealed that specific lncRNAs may regulate the expression of inflammation- and angiogenesis-related genes by interacting with miRNAs, such as NEAT1/hsa-miR-500a-3p/SIGLEC8, NEAT1/hsa-miR-6835–3p/SLC16A14, OIP5-AS1/miR-183–5p/EGR1, and SNHG25/hsa-miR-663a/FOSB axes. ConclusionThis study characterized a thorough profile of human lncRNAs following short-term ozone exposure and suggested the regulatory roles of these lncRNAs in ozone-induced inflammatory responses and angiogenesis, providing novel epigenetic insights into the mechanisms of the health effects of ozone exposure.

The Impact of K-pop Merchandise on the Consumer Behavior of University Students in Shanghai

K-pop merchandise, as one of the main trends in current fashion development, is continuously expanding its audience and influence, particularly among teenagers. This paper conducts a comprehensive study on the impact of K-pop merchandise on the consumer behavior of university students in Shanghai through surveys and interviews. It aims to analyze the consumption behaviors and preferences of these students concerning K-pop merchandise, thereby exploring the significant effects of K-pop merchandise on this student group. The study finds that the consumption behavior of Shanghai university students regarding K-pop merchandise has long-term characteristics. Their purchasing decisions are directly influenced by their internal economic levels and indirectly by the external behaviors of fan communities. However, the cognitive and rational levels of university students are also improving, and their consumption behavior towards K-pop merchandise is shifting towards more rational and value-based decision-making. Overall, the influence and reach of K-pop merchandise are growing, and it is expected to have a sustained impact on the consumption behavior of university students in Shanghai in the future.

The effects of emotion and COVID-19 context priming on the size and color of drawings: based on human figure drawings and tree drawings.

This study aimed to investigate the effects of emotional themes and the COVID-19 pandemic context priming on the size and color of drawings. A 3 (emotion: peacefulness, gratitude, loneliness) × 2 (context: pandemic, regular) mixed design was used and 113 university students in Shanghai were recruited to draw human figures and trees using 10 marker colors. The size of the drawings depicting loneliness was smaller than that of the those depicting peacefulness and gratitude. Drawings depicting loneliness used more cool and non-preferred colors; drawings depicting gratitude used more warm and preferred colors. Drawings in the pandemic context were larger, which may reflect the more significant threat perceived by individuals. Drawings in the pandemic context used more red colors, showing symbolic meanings such as danger. The drawing size and drawing color are influenced by emotional themes and the pandemic context priming.

Analysis of Influential Factors of Fund Purchasing Behavior Based on Multimodality--Based on College Students in Shanghai at Pudong New Area

The purpose of this paper is to study the behavior of college students in purchasing funds and their influencing factors. By distributing online and offline paper questionnaires to college students in Pudong New Area, Shanghai, and at the same time, obtaining first-hand information about college students' fund purchasing through the Internet. According to the survey results of the questionnaire, followed by the analysis of the characteristics of the fund purchasing behavior of college students in Pudong New Area, using the decision tree model to analyze the fund purchasing behavior and purchasing decision, through the questionnaire research and the Zhihu comment crawler to draw the word cloud diagram to derive the different influencing behaviors of college students on the purchase of funds, and the use of LDA sentiment analysis model to derive the double comments of college students in Pudong New Area on the attitude of fund purchasing. The following main conclusions were obtained through this research study:1) Social media communication has become a key factor influencing fund purchases, with college students prioritizing news media and online bloggers for initial understanding before purchasing funds;2) College students' purchase of funds is highly enthusiastic but mostly experimental. Due to their insufficient understanding of the fund market and small sources of income, they choose low-risk funds for experimentation. Undergraduates' financial knowledge is shallow and their ability to bear economic risks is weak, and they lack sufficient knowledge and experience in financial literacy. Finally, the correlation suggestions are put forward: refuse to blindly follow a single source of information to buy funds; some undergraduates have little financial knowledge and buy more impulsively; keep a good mindset of long-term investment, not caring about the momentary gains and losses.

Reliability and validity of the Chinese version of the achievement emotions questionnaire for physical education in university students

BackgroundAchievement emotions have a significant impact on both the learning process and outcomes. However, there is currently no brief and effective questionnaire available to evaluate Chinese university students' achievement emotions in physical education courses. This study aimed to examine the reliability and validity of the Achievement Emotions for Physical Education Questionnaire (AEQ-PE) in a sample of Chinese university students, while also investigating its measurement invariance across gender and grade levels.MethodsA cluster randomization sampling method was used to select 694 first- and second-year university students in Shanghai, China for the survey. Descriptive statistics, item analysis, reliability testing, and measurement invariance testing were conducted on the full sample (n = 694). Subsequently, the full sample was randomly divided into two groups, with Sample 1 (n = 347) undergoing exploratory factor analysis (EFA), and Sample 2 (n = 347) undergoing confirmatory factor analysis (CFA) to test the structural validity, convergent validity, and discriminant validity of the Chinese version of the Achievement Emotions Questionnaire for Physical Education (AEQ-PE-C). Finally, Sample 3 (n = 45), which was retested one month later, was used to evaluate test–retest reliability.ResultsThe Chinese version of the Achievement Emotions Questionnaire for Physical Education consists of 6 dimensions and 24 items, with good item discrimination. The EFA supported a 6-factor structure model, while the CFA demonstrated good model fit indices (χ2/df = 3.086, CFI = 0.928, TLI = 0.916, RMSEA = 0.078) and good convergent and discriminant validity. The questionnaire exhibits high internal consistency reliability (0.794) and excellent test–retest reliability (0.792). Furthermore, the multi-group analysis confirms that the AEQ-PE-C questionnaire has measurement invariance across gender and grade levels.ConclusionThe Chinese version of the Achievement Emotions Questionnaire for Physical Education has good reliability and validity, as well as measurement invariance across gender and grade levels, making it an effective tool for measuring achievement emotions in physical education among Chinese university students.

Cultural Distance, Classroom Silence and Culturally Responsive and Inclusive Education: Evidences from Migrant College Students in Shanghai.

This paper investigated the relationship between cultural distance, classroom silence, and the performance of culturally responsive and inclusive education (CRIE) using a survey of 1051 college students in Shanghai in 2022. We found a significantly positive association between migrant students' cultural distance and their perceived learning gains in class. Students' cultural distance increased their classroom silence as a form of protection but had no significant effect on their classroom silence as a sign of power. The classroom silence as protection decreased students' perceived learning gains. However, classroom silence as power could be used by both local and migrant students as a hold-up strategy to strengthen their influence in class discussions, which could improve their perceived learning gains. Teachers' CRIE played the most important role in migrant students' perceived learning gains, while the effectiveness of CRIE was also actually dependent on the different channels and mechanisms of cultural distance and classroom silence. A cautious identification of classroom silence will improve the effectiveness of CRIE. Suggestions are offered to lighten the practice of educators, administrators, and instructors who face classroom silence from subnational migrant students.

Research on the employment of college students in Shanghai under the normalization of COVID-19 control

Since the outbreak of COVID-19, the domestic and foreign economies have been facing downward pressure, and employers' demand for the labor force has declined, reducing the number of jobs recruited for college graduates. With COVID-19 control becoming the requirement of normalization, the epidemic's impact on the employment of college graduates will continue. In this regard, this paper analyzes the employment problems and relevant countermeasures of Shanghai college graduates under the current normalization of COVID-19 control. It then puts forward countermeasures and suggestions for employment problems from the perspective of the government and colleges.

Mechanistic insights into the health benefits of fish-oil supplementation against fine particulate matter air pollution: a randomized controlled trial

Background:Dietary fish-oil supplementation might attenuate the associations between fine particulate matter (PM2.5) and subclinical biomarkers. However, the molecular mechanisms remain to be elucidated. This study aimed to explore the molecular mechanisms of fish-oil supplementation against the PM2.5-induced health effects.Methods:We conducted a randomized, double-blinded, and placebo-controlled trial among healthy college students in Shanghai, China, from September 2017 to January 2018. A total of 70 participants from the Fenglin campus of Fudan University were included. We randomly assigned participants to either supplementation of 2.5-gram fish oil (n = 35) or sunflower-seed oil (placebo) (n = 35) per day and conducted four rounds of health measurements in the last two months of the trial. As a post hoc exploratory study, the present untargeted metabolomics analysis used remaining blood samples collected in the previous trial and applied a Metabolome-Wide Association Study framework to compare the effects of PM2.5 on the metabolic profile between the sunflower-seed oil and fish oil groups.Results:A total of 65 participants completed the trial (34 of the fish oil group and 31 of the sunflower-seed oil group). On average, ambient PM2.5 concentration on the day of health measurements was 34.9 µg/m3 in the sunflower-seed oil group and 34.5 µg/m3 in the fish oil group, respectively. A total of 3833 metabolites were significantly associated with PM2.5 in the sunflower-seed oil group and 1757 in the fish oil group. Of these, 1752 metabolites showed significant between-group differences. The identified differential metabolites included arachidonic acid derivatives, omega-3 fatty acids, omega-6 fatty acids, and omega-9 fatty acids that were related to unsaturated fatty acid metabolism, which plays a role in the inflammatory responses.Conclusion:This trial suggests fish-oil supplementation could mitigate the PM2.5-induced inflammatory responses via modulating fatty acid metabolism, providing biological plausibility for the health benefits of fish-oil supplementation against PM2.5 exposure.Trial registration:This study is registered at ClinicalTrails.gov (NCT03255187).

Government's impression management strategies, trust in government and social cohesion: An evidence from Songjiang University Town, China.

Trust in government and social cohesion are crucial guarantees for long-term social stability. With the development of the Internet, cross-border flows of information have become increasingly easier, enabling more factors to influence people’s political perceptions and loyalty. This study explores the mechanism of governments’ impression management behaviors on trust in government and social cohesion using the questionnaire survey with college students in Shanghai as the research subjects. Impression management strategies are classified into promotive ones and protective ones herein based on the social psychology theory. The results indicate that both promotive and protective impression management strategies take by governments positively affect citizens’ loyalty, and loyalty positively affects citizens’ social cohesion and the level of trust in government; moreover, the level of trust in government positively affects social cohesion. These findings provide implications for boosting the sound development of China’s political society during the transition period.

Characterization of plasma-derived exosomal miRNA changes following traffic-related air pollution exposure: A randomized, crossover trial based on small RNA sequencing.

The underlying mechanisms for health effects of traffic-related air pollution (TRAP) are still unclear. Small RNA sequencing (RNA-seq) in exosomes represents as a powerful approach to elucidate biological pathways in response to environmental exposure. We therefore aimed to explore impact of TRAP exposure on exosomal miRNAs. We performed a randomized, crossover study among 35 healthy college students in Shanghai, China. Participants were randomly assigned to 4-hour exposure in a traffic-polluted Road and in a traffic-free Park, respectively, intermitted by a washout period (at least 2weeks). RNA-seq was conducted to identify plasma-derived exosomal miRNAs and the differential miRNAs were explored using linear mixed-effect models. Pathway enrichment was conducted using ingenuity pathway analysis. Further, we validated several selected miRNAs by droplet digital PCR (ddPCR). The average concentrations of air pollutants including ultrafine particles, black carbon, nitrogen dioxide, and carbon dioxide were 2-3 times higher in the Road compared to those in the Park. We identified 271 exosomal miRNAs (212 up-regulated and 59 down-regulated) that were significantly associated with TRAP. We found 5 miRNAs with 242 experimentally validated mRNA targets that were involved in cardiovascular pathway, cytokine signaling, and immune response. The ddPCR analysis suggested that miR-3612, miR-21-5p, and miR-195-5p were significantly changed following TRAP exposure. For the first time this trial characterized the genome-wide changes of exosomal miRNA associated with TRAP exposure. The molecular profiling of exosomal miRNAs and "novel" associations of some miRNAs were useful for understanding on biological mechanisms for the adverse effects of TRAP.

Prevalence and risk factors associated with self-reported psychological distress among college students during the omicron outbreak in Shanghai.

BackgroundMore and more attention has been paid to the mental health of students in higher education. The Omicron outbreak has brought renewed attention to this vulnerable group.ObjectiveTo understand the prevalence and influencing factors of anxiety symptoms and depression symptoms of college students in a closed state.MethodsThis large cross-sectional study using data from a survey on the mental health of college students in Shanghai (China), conducted by using a stratified cluster random sampling method between March 15th and April 15th, 2022. To estimate results related to regional location, only data from students with Internet protocol addresses and current addresses in Shanghai were included. The main outcome was self-reported psychological distress (including depressive symptoms, anxiety symptoms, and self-assessment of health), measured using the epidemiologic studies depression scale (CES-D), the Spielberger state-trait anxiety inventory (STAI) and self-rated mental health (SRMH), respectively. Moreover, the Simplified Coping Style Scale (SCSS) was also used to assess how participants coped with negative emotions.ResultsAmong 13,000 college students who completed the survey, 12,124 students were included in the final analysis, and the total effective rate was 93.3%. The prevalence of depressive symptoms and anxiety symptoms were 14.1 and 9.8%, respectively. By using Multivariate logistics regression analysis, we found that being male and negative coping were risk factors for depressive symptoms and anxiety symptoms, while positive coping, such as study or learning, were protective factors. Moreover, linear regression analysis showed that learning or study improved the overall mental health index by improving anxiety or depressive symptoms, and played a partial mediating role.ConclusionsThese findings suggest that a significant number of college students, especially boys, will experience emotional problems during the course of closed schools. Therefore, we need to give them proper attention and advise them to adopt positive coping strategies, such as learning or study, to resist bad emotions.

Effects of Cell Phone Dependence on Mental Health Among College Students During the Pandemic of COVID-19: A Cross-Sectional Survey of a Medical University in Shanghai.

ObjectiveTo investigate the effects of cell phone dependence (CPD) on mental health among undergraduates during the COVID-19 pandemic and further identify the determinants that may affect their mental health in China.MethodsThe data were collected from 602 students at a medical school in Shanghai via an online survey conducted from December 2021 to February 2022. The Mobile Phone Addiction Index (MPAI) and Depression Anxiety Stress Scale (DASS) were applied to evaluate CPD and mental health, respectively. Independent sample t-test and one-way analysis of variance (ANOVA) were employed to compare the means of continuous variables among categorical groups. Correlations between continuous variables were detected using Pearson's correlation analysis. Univariable and multivariable logistic regressions were employed to identify the determinants of mental health.ResultsAmong the 402 eligible students, 73.88% were women with an average age of 20.19 ± 2.36 years. On average, the DASS score was 32.20 ± 11.07, the CPD score was 36.23 ± 11.89, and the cell phone use duration was 7.67 ± 3.61 h/day. CPD was found to have a negative effect on mental health among college students in Shanghai. Additionally, cell phone use duration, age, being senior students, faculty-student relationship, insomnia, tobacco use, obesity, and life satisfaction were clarified as contributing factors to mental health among college students.ConclusionHigh degree of CPD could have a negative effect on college students' mental health, which might lead to some psychological problems. Appropriate actions and effective interventions are highly needed to prevent severe psychological injuries among college students in China.

Personal ozone exposure and stress hormones in the hypothalamus-pituitary-adrenal and sympathetic-adrenal-medullary axes.

The effect of ozone exposure on neuroendocrine responses in humans has not been fully studied. We conducted a longitudinal panel study with four rounds of visits among 43 college students in Shanghai, China, from May to October 2016. For each visit, we monitored personal real-time ozone exposure for consecutive 3days (from 8:00 a.m. to 6:00p.m. each day), followed by blood sample collection. We measured serum levels of three hormones in the hypothalamus-pituitaryadrenal (HPA) axis, including corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and cortisol, and three catacholamines indicating sympathetic-adrenal-medullary (SAM) axis activation, including adrenaline, noradrenaline, and dopamine. We applied linear mixed-effect models to evaluate the associations between ozone exposure and these neurohormones and further compared models using personal and fixed-site ozone measurements. At lag 0-8h, personal ozone exposure ranged from 4.5ppb to 104.3ppb with an average of 21.0±14.7ppb, which was approximately half of the ambient ozone concentration. Per 10-ppb increase in personal ozone exposure (lag 0-8h) was associated with increases of 5.60% [95% confidence interval (CI): 2.30%, 9.01%] in CRH, 5.91% (95% CI: 0.55%, 11.56%) in cortisol, and 10.13% (95% CI: 2.75%, 18.05%) in noradrenaline, whereas associated with a 12.15% (95% CI: 1.23%, 21.87%) decrease in dopamine. Overall, models using personal ozone measurements yielded larger effect estimates and better model fits than models using fixed-site measurements. Short-term exposure to low levels of ozone may lead to activation of the HPA and SAM axes.

Personal exposure to fine particulate matter and blood pressure: Variations by particulate sources

Fine particulate matter (PM2.5) is a complex mixture of components which has been associated with various cardiovascular effects, such as elevated blood pressure (BP). However, evidences on specific sources behind these effects remain uncertain. Based on 140 72-h personal measurements among a panel of 36 health college students in Shanghai, China, we assessed associations between source-apportioned PM2.5 exposure and BP changes. Based on personal filter samples, PM2.5 source apportionment was conducted using Positive Matrix Factorization (PMF) model. Linear mixed-effects models were applied to evaluate associations of source-specific PM2.5 exposure with BP changes. Seven sources were identified in PMF analysis. Among them, secondary sulfate (41%) and nitrate (24%) sources contributed most to personal PM2.5, followed by industrial emissions (15%), traffic-related source (10%), coal combustion (6.2%), dust (2.4%) and aged sea salt (1.1%). We found nitrate, traffic-related source and coal combustion were significantly associated with increased BP. For example, an interquartile range increase in PM2.5 from traffic-related source was significantly associated with increase in systolic BP [1.5 (95% CI: 0.26, 2.7) mmHg], diastolic BP [1.2 (95% CI: 0.10, 2.2) mmHg] and mean arterial pressure [1.2 (95% CI: 0.15, 2.2) mmHg]. This is the first investigation linking personal PM2.5 source profile and BP changes. This study provides evidence that several anthropogenic emissions (especially traffic-related emission) may be particularly responsible for BP increases, and highlights that the importance of development of health-oriented PM2.5 source control strategies.

Negotiating Identity tensions in multilingual learning in China: a situated perspective on language learning motivation and multilingual identity

ABSTRACT In accordance with the multilingual turn in SLA (May, S. 2014. Introducing the ‘multilingual turn’. In The Multilingual Turn: Implications for SLA, TESOL and Bilingual Education, ed. S. May, 1–6. New York, NY: Routledge), researchers are now directing more attention to the motivational dynamics associated with learning multiple languages, including the interrelationships between motivation and learners’ sense of self. In contrast to research focused on language learners’ psychological relationship to languages from the perspective of self-systems, this research instead takes a more identity-focused perspective that looks at motivation in light of learners’ orientations towards ideological discourses associated with languages. It draws on longitudinal qualitative interviews and supplementary data from five Chinese university students in Shanghai who are majoring in Japanese while continuing to study English. The analysis highlights that the learners experienced a number of important identity-tensions as they attempted to reconcile ideological discourses on language with their own multi-layered identity positions and perspectives towards language learning. The discussion details the ways that learners mobilise their interpretive resources to evaluate instrumental and humanistic orientations towards language within macro-, meso- and micro- contexts and make agentive decisions that shape their motivational trajectories and multilingual identities.

Family relationship and psychological stress response of college students in Shanghai under the COVID-19 epidemic

Objective: To investigate the association between the family relationship of college students in Shanghai and the psychological stress response under the COVID-19 epidemic.

Chinese women's autonomy: parenthood as a choice

Numerous Chinese studies point out that Chinese youth are transforming the meaning of filial piety, China's highly esteemed moral code used to structure intergenerational relationships. We wanted to understand the extent to which college educated women are redefining what it means to be a filial woman in contemporary Chinese society. To this end, we set up a research design that probed whether men and women continue to think becoming parents is an essential attribute of life satisfaction using a pen-and-paper survey with college students in Shanghai and Hohhot, Inner Mongolia. A Principal Components Analysis (PCA) on Likert-scaled questions resulted in two factors: Customary Ideology and Autonomous Self. As anticipated, students who reported their intent to parent were more likely to agree with items in Customary Ideology, whilst students who reported not intending to have children or were uncertain were more likely to agree with items in Autonomous Self. Most telling, an overwhelming number of respondents from each university reported agreement with the statement, "Having children is a personal choice" (97.6% at Fudan University; 76.4% at Inner Mongolia University). We discuss the implications of these findings as the singleton generations renegotiate expectations of these intergenerational bonds.
