How social background and interest in science are linked to junior high school students' perceptions of the ecological transition.

Junior high school students are tomorrow's key protagonists in the ecological transition. They need enlightened education to face the uncertainty and challenges of climate change. The development of climate change education programs requires a clear understanding of how young people perceive the issue. This study deals with social representations. Its aim was to understand how social background and interest in science are linked to the way young people perceive the concept of the ecological transition. Four hundred twenty-nine junior high school students took part in this study. Data were collected and subjected to prototypical analysis and factorial correspondence analysis. Three main findings emerged from the analysis: (1) the participants had significant knowledge of the ecological transition, (2) their awareness of the social aspects of climate change was limited, and (3) their representations of the ecological transition were linked to their interest in science and their parents' social background. To conclude, these results underline the importance of educating all social classes about effective solutions for the ecological transition. Our findings also highlight the need to consider existing representations and prior knowledge when designing educational programs on climate change issues.

Lawn or spontaneous groundcover? Residents' perceptions of and preferences for alternative lawns in Xianyang, China.

Within urban green spaces, spontaneous groundcovers, as potential alternatives for traditional lawns, have garnered attention due to their ecological adaptability. However, little attention has been paid to whether spontaneous groundcovers can serve as suitable replacements for lawns in terms of the aesthetic values and human preferences for each. Based on questionnaires accompanied by photo elicitation, this study explored the perceptions of and preferences for seven kinds of lawns and six kinds of spontaneous groundcovers in China. The effects of social backgrounds on people's perceptions of and preferences for ground covers were also analyzed. The results indicated a general equivalence in preferences for the lawn and spontaneous groundcover. The Taraxacum mongolicum - Cynodon dactylon - Conyza canadensis community was significantly preferred most among all of the selected ground covers. Spontaneous groundcovers were regarded as more natural, wild, variable, and species-richer compared to lawns, while lawns were perceived as better kept than spontaneous groundcovers. Ground covers were preferred which were perceived to have high ecological aesthetic value and low wildness. Industry and attention to herbaceous plants mostly affected human perceptions and preferences among the social background factors, and gender, age, education level, and occupation also had significant effects. The results thus provide the support for the application of spontaneous groundcovers in moderately developed cities, but such application should consider the comprehensive development of ecological aesthetic value and the applicability of different groups of residents.

Determinants for participation in a prevention and early detection programme for children and adolescents in Germany: does social background play a role?

Early detection examinations and prevention are particularly important in childhood and adolescence, as certain diseases are already developing and health-related attitudes and behaviour patterns are formed and implemented. Despite the importance of screening and prevention, not all families use the available services and programmes. The aim of this study is to identify factors associated with participation in an early detection and prevention programme for children and adolescents, as well as factors associated with actual uptake of an examination. The analyses are based on questionnaire data of an online survey of participants and non-participants. Descriptive analyses and logistic regression models are conducted on a defined sample (n = 1,289). The results show that both groups differ with regard to several factors: age, chronic diseases, federal state, living space, number of siblings, country of birth, migration background, language spoken at home, mother's occupational status, household income, treatment duration, and trust in treating physician. Regression I shows that participation in the programme is significantly associated with higher age, language spoken at home, mother's occupational status and greater trust in the treating physician. The latter demonstrates the highest predictive power. Regression II indicates that the actual uptake of an examination among participants is significantly affected by age, federal state and father's occupational status. Overall, the results of this study show that social background partly plays a role in participation, but that factors such as trust in the treating physician also have a significant impact. For the future, further research on the factors influencing participation in screening and prevention services or programmes for children and adolescents is important in order to develop strategies to overcome existing barriers and thus reach groups that have not been reached yet. In this context, trust in the treating physician and his or her influence on decision-making should in particular be considered.

Research on the impact mechanism of enterprise green technology innovation based on the analysis framework of theory of planned behavior: evidence from heavily polluting listed enterprises in China.

Under the background of China's ecological civilization construction, enterprises green technology innovation (GTI) has attracted more and more attention. In this paper, the internal factors and external factors, subjective factors, and objective factors of each relevant subject are comprehensively considered, and the analysis framework of the impact mechanism of enterprise GTI is constructed. Then, taking 211 heavily polluting listed enterprises in China from 2010 to 2019 as the sample, integrating the mediating effect model and the moderating effect model, this paper empirically discusses the relationships among corporate endowments, executive characteristics, and enterprise GTI. The results demonstrate that corporate endowments have a positive impact on GTI, and executive characteristics act on GTI as a mediating variable during the impact process; market forces respectively play a weakening and strengthening role in moderating the main effect and the intermediate effect; government intervention and social background have positive moderating effects on the relationship between executive characteristics and GTI; the three moderating variables have a remarkable joint-moderating effect on the relationships between executive characteristics and GTI.

Social and genetic associations with educational performance in a Scandinavian welfare state.

Recent research has suggested that across Western developed societies, the influence of genetics on educational outcomes is relatively constant. However, the degree to which family environment matters varies, such that countries with high levels of intergenerational mobility have weaker associations of family background. Research in this vein has relied on twin-based estimates, which involve variance decomposition, so direct assessment of the association of genes and environments is not possible. In the present study, we approach the question by directly measuring the impact of child genotype, parental genetic nurture, and parental realized education on educational achievement in primary and secondary school. We deploy data from a social democratic context (Norway) and contrast our findings with those derived from more liberal welfare state contexts. Results point to genetics only confounding the relationship between parent status and offspring achievement to a small degree. Genetic nurture associations are similar to those in other societies. We find no, or very small, gene-environment interactions and parent-child genotype interactions with respect to test scores. In sum, in a Scandinavian welfare state context, both genetic and environmental associations are of similar magnitude as in societies with less-robust efforts to mitigate the influence of family background.

News Stance Discrimination Based on a Heterogeneous Network of Social Background Information Fusion.

Media with partisan tendencies publish news articles to support their preferred political parties to guide the direction of public opinion. Therefore, discovering political bias in news texts has important practical significance for national election prediction and public opinion management. Some biased news often has obscure expressions and ambiguous writing styles. By bypassing the language model, the accuracy of methods that rely on news semantic information for position discrimination is low. This manuscript proposes a news standpoint discrimination method based on social background information fusion heterogeneous network. This method expands the judgment ability of creators and topics on news standpoints from external information and fine-grained topics based on news semantics. Multi-attribute features of nodes enrich the feature representation of nodes, and joint representation of heterogeneous networks can reduce the dependence of position discrimination on the news semantic information. To effectively deal with the position discrimination of new news, the design of a multi-attribute fusion heterogeneous network is extended to inductive learning, avoiding the cost of model training caused by recomposition. Based on the Allsides dataset, this manuscript expands the information of its creator's social background and compares the model for discriminating political positions based on news content. In the experiment, the best transductive attribute fusion heterogeneous network achieved an accuracy of 92.24% and a macro F1 value of 92.05%. The effect is improved based purely on semantic information for position discrimination, which proves the effectiveness of the model design.

Motives and Barriers Related to Physical Activity and Sport across Social Backgrounds: Implications for Health Promotion.

Studies have found physical inactivity to be a significant health risk factor and have demonstrated how physical inactivity behaviour varies according to social background. As a result, differences according to social background must be considered when examining motives and barriers related to physical activity and sport. This scoping review examines motives and barriers related to physical activity and sport among people with different social backgrounds, including age, socioeconomic status, gender, ethnic minority background and disability status. A systematic literature search was performed in four scientific databases and yielded 2935 articles of which 58 articles met the inclusion criteria. We identified common motives for physical activity and sport as health benefits, well-being, enjoyment, social interaction, and social support; common barriers as time restrictions, fatigue and lack of energy, financial restrictions, health-related restrictions, low motivation, and shortage of facilities. We also identified several motives and barriers that were specific to or more pronounced among people with different social backgrounds. The knowledge about motives and barriers related to physical activity and sport provided in this article can inform health promotion initiatives that seek to improve public health both in general and when specifically targeting groups of people with different social backgrounds.

Social and Family Factors as Determinants of Sleep Habits in Japanese Elementary School Children: A Cross-Sectional Study from the Super Shokuiku School Project.

This study explored the associations of lifestyle, familial, and social factors with sleep habits in 1882 elementary school children, aged 6-13 years, from the Super Shokuiku School Project in January 2016. A survey assessed sex, grade, sleep habits, lifestyle, social background, and parental lifestyle. Bedtime "≥22:00," wake-up time "≥07:00," sleep duration "<8 h," and "daytime sleepiness" were defined as poor sleep habits; correlates were analyzed using logistic regression. Skipping breakfast was consistently significantly associated with poor sleep, especially among children with late wake-up times (adjusted odds ratio 5.45; 95% confidence interval 3.20-9.30). Excessive screen time was associated with late bed and wake-up times. Physical inactivity was significantly associated with daytime sleepiness. Children of mothers with poor lifestyle habits were likely to go to bed late and feel sleepy the next day. Social and family factors were associated with children's sleep habits. Several behaviors, including skipping breakfast, excessive screen time, and physical inactivity, were associated with poor sleep habits, manifesting as a night-oriented lifestyle. Although a longitudinal study is needed to determine causality, in addition to sleep education for children, sleep education for parents and society at large may be necessary to improve children's sleep habits.

Social and family factors as determinants of exercise habits in Japanese elementary school children: a cross-sectional study from the Super Shokuiku School Project.

BACKGROUND: Many studies have already reported on the relationship between exercise habits and health among schoolchildren. However, few have examined social and/or family factors as determinants of exercise habits. METHODS: This study's participants included 1721 schoolchildren aged between 6 and 13 who were involved in the Super Shokuiku School Project in January 2016. A survey was conducted to assess gender, grade level, physical activity, lifestyle, overall health, enrichment of school life, social background, and parental lifestyles. Both dislike and lack of physical activity were used to measure poor exercise habits; correlates were analyzed using logistic regression. RESULTS: "Lack of close friends" had the strongest links with both dislike (adjusted odds ratio [OR] 5.30; 95% confidence interval [CI], 2.78-10.1) and lack of (adjusted OR 5.40; 95% CI, 2.81-10.4) physical activity. Further, children who engaged in long periods of screen time and lacked parental communication also tended to dislike and lack physical activity. Children with mothers who were unemployed (housewives) and had unhealthy lifestyles, as well as those with poor health, were also more likely to lack physical activity. CONCLUSION: Social and family factors (e.g., having close friends) may be determinants of exercise habits among schoolchildren, independent of their own lifestyle factors. Although a longitudinal study is needed to determine causality, substantial attention may thus be required to these factors when promoting physical activity in children.

Requiem for a Dream: Perceived Economic Conditions and Subjective Well-Being in Times of Prosperity and Economic Crisis.

Using the Panel of Social Inequalities in Catalonia, Spain (PaD 2001-2012), this article investigates the relationship between perceptions of economic conditions and subjective well-being in times of prosperity and economic crisis. It also analyses how this relationship plays out across different social backgrounds. Periods of economic crisis and prosperity serve as a proxy for objective macroeconomic conditions. The Spanish region of Catalonia is a relevant setting because it faced one of the highest increases in inequality and unemployment in Europe as a result of the 2008 Economic Crisis. Our results show that perceived economic conditions matter beyond objective micro and macroeconomic realm and become a strong determinant of subjective well-being during a crisis, particularly for the middle class. However, contrary to our initial expectations, our results also show the existence of a close correlation between perceptions of economic conditions and subjective well-being for low social background individuals in times of economic prosperity, and an even stronger relationship in times of economic crisis. The article stipulates several potential explanations for these results.

Effectiveness of a physical activity intervention in preschoolers: A cluster-randomized controlled trial.

Several activity interventions in preschool settings exist, but little attention has been paid to effects on hemodynamic factors. The study aimed to assess the effectiveness of an exercise program on health-related outcomes including blood pressure (BP) and markers of vascular function in preschoolers, with focus on socioeconomic background. This study is a cluster-randomized controlled trial, with preschool as unit of randomization and children as unit of analysis. Preschools with 3- to 6-year-old children, stratified by social area, were randomly allocated to: intervention (three clusters, n = 92) including 2 d·wk-1 /45 min (6 months) exercise lessons or control (two clusters, n = 43). In total, 135 children (4.8 ± 0.8 y) had minimum one outcome measurement at baseline and follow-up. Primary outcome: peripheral BP. Secondary outcomes: central BP, pulse wave velocity (PWV), BMI, waist circumference, physical activity measures, motor skills. Maternal education was used as an indicator of socioeconomic status. Mixed models were applied to evaluate differences in mean change. Group allocation had no effect on primary or secondary outcomes. However, the intervention was effective in reducing increases in peripheral systolic BP (-3.4 mm Hg; 95% CI: -6.6; -0.2; P = 0.037), central systolic BP (-3.8 mm Hg; -6.4; -1.1; P = 0.006), and PWV (-0.1 m/s; -0.2; -0.0; P = 0.045) among children whose mothers had the lowest educational level. We found no evidence for effectiveness of a 6-months preschool-based exercise program on hemodynamics, anthropometrics, activity, or motor skills, but lack of process evaluations and poor fidelity preclude interpretation of the causal relation. However, the results indicate that children from lower social backgrounds could benefit from early exercise-promoting interventions.

A decline in activities of daily living due to acute heart failure is an independent risk factor of hospitalization for heart failure and mortality.

BACKGROUND: Although activities of daily living (ADL) are recognized as being pertinent in averting relevant readmission of heart failure (HF) and mortality, little research has been conducted to assess a correlation between a decline in ADL and outcomes in HF patients. METHODS: The Kitakawachi Clinical Background and Outcome of Heart Failure Registry is a prospective, multicenter, community-based cohort of HF patients. We categorized the patients into four types of ADL: independent outdoor walking, independent indoor walking, indoor walking with assistance, and abasia. We defined a decline in ADL (decline ADL) as downgrade of ADL and others (non-decline ADL) as preservation of ADL before discharge compared with admission. RESULTS: Among 1253 registered patients, 923 were eligible, comprising 98 (10.6%) with decline ADL and 825 (89.4%) with non-decline ADL. Decline ADL exhibited a higher risk of hospitalization for HF and mortality compared with non-decline ADL. A multivariate analysis revealed that decline ADL emerged as an independent risk factor of hospitalization for HF [hazard ratio (HR), 1.42; 95% confidence interval (CI): 1.01-1.96; p=0.046] and mortality (HR, 1.95; 95% CI: 1.23-2.99; p<0.01). Although 66.3% of patients with decline ADL were registered for long-term care insurance, few received daycare services (32.7%) or home-visit medical services (8.2%). CONCLUSIONS: Decline in ADL is a predictor of hospitalization for HF and mortality in HF patients.

Structural and motivational mechanisms of academic achievement: a mediation model of social-background effects on academic achievement.

This paper takes up ongoing discussions on the inequality of educational opportunities and formulates a conceptual model to link separate lines of research. Our particular focus is on combining motivational and structural approaches into a mediation model that explains differences in academic achievement. In the literature, four main mechanisms of social reproduction are discussed. Two main pathways refer to (1) parents' expectations regarding their children's academic success and (2) replicating cultural capital through intra-familial cultural practices. (3) Parents' perception of children's abilities depends on social position and is influential for expectations of success. (4) For all three pathways, we expect effects on students' motivational characteristics, which in turn influence academic achievement. We test our conceptual model by structural equation modelling using longitudinal data from primary school students in Germany. Empirical evidence is in line with the assumptions in the model. Cultural reproduction and expectations of success can be seen as the key components of the model. However, both chains of reproduction are related to each other by parents' perception of child's ability, and their effects are mediated by child's motivational characteristics.

The language and social background questionnaire: Assessing degree of bilingualism in a diverse population.

Research examining the cognitive consequences of bilingualism has expanded rapidly in recent years and has revealed effects on aspects of cognition across the lifespan. However, these effects are difficult to find in studies investigating young adults. One problem is that there is no standard definition of bilingualism or means of evaluating degree of bilingualism in individual participants, making it difficult to directly compare the results of different studies. Here, we describe an instrument developed to assess degree of bilingualism for young adults who live in diverse communities in which English is the official language. We demonstrate the reliability and validity of the instrument in analyses based on 408 participants. The relevant factors for describing degree of bilingualism are: (1) the extent of non-English language proficiency and use at home, and (2) non-English language use socially. We then use the bilingualism scores obtained from the instrument to demonstrate their association with: (1) performance on executive function tasks, and (2) previous classifications of participants into categories of monolinguals and bilinguals.

Patient-reported adverse events after hernia surgery and socio-economic status: A register-based cohort study.

BACKGROUND: The aim of the present study was to assess how socio-economic background influences perception of an adverse postoperative event after hernia surgery, and to see if this affects the pattern of seeking healthcare advice during the early postoperative period. MATERIALS AND METHODS: All patients aged 15 years or older with a primary unilateral inguinal or femoral hernia repair recorded in the Swedish Hernia Register (SHR) between November 1 and December 31, 2002 were sent a questionnaire inquiring about adverse events. Data on civil status, income, level of education and ethnic background were obtained from Statistics Sweden. RESULTS: Of the 1643 patients contacted, 1440 (87.6%) responded: 1333 (92.6%) were men and 107 (7.4%) women, mean age was 59 years. There were 203 (12.4%) non-responders. Adverse events were reported in the questionnaire by 390 (27.1%) patients. Patients born in Sweden and patients with high income levels reported a significantly higher incidence of perceived adverse events (p < 0.05). Patients born in Sweden and females reported more events requiring healthcare contact. There was no association between registered and self-reported outcome and civil status or level of education. CONCLUSION: We detected inequalities related to income level, gender and ethnic background. Even if healthcare utilization is influenced by socio-economic background, careful information of what may be expected in the postoperative period and how adverse events should be managed could lead to reduced disparity and improved quality of care in the community at large.

Ethnic and social disparities in different types of examinations in undergraduate pre-clinical training.

Medical schools are increasingly faced with a more diverse student population. Generally, ethnic minority students are reported to underperform compared with those from the ethnic majority. However, there are inconsistencies in findings in different types of examinations. Additionally, little is known about the performance of first-generation university students and about performance differences across ethnic minority groups. This study aimed to investigate underperformance across ethnic minority groups and by first-generation university students in different types of written tests and clinical skills examinations during pre-clinical training. A longitudinal prospective cohort study of progress on a 3-year Dutch Bachelor of Medicine course was conducted. Participants included 2432 students who entered the course over a consecutive 6-year period (2008-2013). Compared with Dutch students, the three non-Western ethnic minority groups (Turkish/Moroccan/African, Surinamese/Antillean and Asian) underperformed in the clinical problem solving tests, the language test and the OSCEs. Findings on the theoretical end-of-block tests and writing skills tests, and results for Western minority students were less consistent. Age, gender, pre-university grade point average and additional socio-demographic variables (including first-generation university student, first language, and medical doctor parent) could explain the ethnicity-related differences in theoretical examinations, but not in language, clinical and writing skills examinations. First-generation university students only underperformed in the language test. Apparently, underperformance differs both across ethnic subgroups and between different types of written and clinical examinations. Medical schools should ensure their assessment strategies create a level playing field for all students and explore reasons for underperformance in the clinical and writing skills examinations.

Changing Social Background Pattern of Children in Adoption Institutions(the 4th Report)

PURPOSE: A study was undertaken to assess the social background of abandoning children at adoption institutions. The results were compared to those of three previous reports from the institution. METHODS: A total of 536 children who had been admitted to the institution during the period of 1993 to 1996 were subjected to the study. The medical records were reviewed retrospectively. RESULTS: The sex ratio of male to female was 1 : 0.9, which was opposite compared to previous studies. Mean birth weight was 2.76+/-0.58kg. The proportion of prematurity was 27.2% and their mean gestational age was 34.0+/-2.25 weeks. The academic background of the mother was mainly high school, comprising 58.4%. The highest rate of maternal age(75.9%) was between 16 to 25 years of age. Maternal age below 15 years was 2.8%, which showed increased in tendency compared to previous studies. Classifying the mother's occupation, they were unemployed(19.4%), office workers(16.8%), store clerks(15.9%), students(13.6%), factory workers(12.3%) and waitresses (5.6%) in this order of frequency. The order of birth showed that the first baby was 89.4%. The reasons for putting their baby up for adoption were they were unmarried(83.2%), poor(8.6%), extramarital birth(3.2%), divorce(2.9%) and death of parents(0.4%) in this order of frequency, showing a significant increased in the rate of unmarried mothers. Only 38.4% of mothers had taken antenatal care. Most of the children (90.8%) were adopted by parents in foreign countries. CONCLUSION: The main reason for adoption was the mothers were unmarried and the maternal age tended to be younger. The rate of foreign adoption was still high.
