ENVIRONMENTAL ACTIVISM AS IDENTITY PROJECT: THE CASE OF STUDENT ENVIRONMENTAL ASSOCIATIONS IN CHINA

Il progetto di ricerca analizza i tratti distintivi dell'identità ecologica promossa da associazioni ambientaliste cinesi e le relative pratiche coinvolte nel processo di gestione delle identità all’interno di piattaforme di social networking. Un secondo livello di analisi indaga le modalità con cui gli attivisti negoziano la loro identificazione con i progetti identitari ecologici attivati dalle organizzazioni di appartenenza. La ricerca etnografica si focalizza su dieci associazioni studentesche attive a Pechino. La metodologia qualitativa include interviste in profondità a membri delle organizzazioni, osservazioni partecipanti delle loro attività, l’analisi qualitativa del contenuto di post condivisi sui loro profili Sina Weibo e Wechat; e dei contenuti condivisi dai membri sui loro profili WeChat Moments tra febbraio e luglio 2016. I risultati rivelano identità ecologiche complesse ed elaborate. Lo studio propone una tassonomia tripartita dei progetti identitari, che include ‘sustainable lifestyle-related identities’, in riferimento alla responsabilità degli studenti nel ridurre il loro impatto ambientale (in relazione alla conservazione di acqua, energia, cibo e pratiche di viaggio sostenibili); ‘investigation-related identities', indicando l'impegno degli studenti nella comprensione delle questioni ambientali e nel contributo alla soluzione delle relative problematiche attraverso azioni concrete; ‘social identities’, riferendosi alla determinazione delle associazioni a occuparsi di questioni sociali, impegnandosi in progetti di beneficenza.The study explores the distinctive features of the environmental identity promoted by Chinese students environmental associations (SEAs), and the social media practices involved in their identity management processes. A second level of analysis investigates how activists negotiate their identification with the environmental identity projects fostered by their organizations. The ethnographic research focuses on ten SEAs located in Beijing. The data collection process is based on extensive usage of in-depth interviews with staff members, participant observations of activities, and content analysis of materials posted on SEAs’ social media accounts (Sina Weibo, WeChat), and materials shared by members on their WeChat Moments over a six-month period (February- July 2016). Results reveal that SEAs environmental identities are plural and composite in themselves. I propose a tripartite taxonomy, which includes sustainable lifestyle-related identities, referring to the responsibility of students to reduce their carbon footprint, by addressing the sources of their impact (in relation to water, energy, food conservation, green travel practices); investigation-related identities, consisting in students’ meaningful engagement in the understanding of environmental issues, and contribution to their solution through concrete action; and social identities, referring to SEAs determination to be concerned about social issues, by engaging in charity projects

Reliability and Validity of the Italian Translation of the UPPS-P Impulsive Behavior Scale in a Sample of Consecutively Admitted Psychotherapy Patients

The present study examined the reliability and validity of the Italian translation of the UPPS-P Impulsive Behavior Scale (UPPS-P) in a clinical sample of 268 consecutively admitted psychotherapy patients (43.3% male; mean age = 40.48 (SD = 12.52); 38.8% inpatient). The Italian UPPS-P replicated the internal consistency coefficients of the original UPPS-P (0.84 to 0.92 across the five subscales). Moreover, confirmatory factor analyses evidenced an adequate fit for the a-priori five-factor model of the scale (WLSMV CFA χ2(1642) = 2833.06, p .10; CFI = .90; TLI = .90). Furthermore, the UPPS-P scales were significantly related to the Barratt Impulsiveness Scale-11 total score (rs = 0.23 to 0.60 across the five scales). Finally, the five UPPS-P scales showed distinct associations with domain scores and interview-based dimensional scores of personality disorders. These findings suggest that the Italian version of the UPPS-P can be considered a valid and reliable alternative to the original UPPS-P and can be a useful diagnostic tool in a clinical sample

Social inequalities, green and blue spaces and mental health in 6–12 years old children participating in the INMA cohort

Availability of green and blue spaces in the area of residence has been related to various health outcomes during childhood, including mental health. These environmental exposures are not evenly distributed among socioeconomic groups, which may increase social inequalities in mental health. The mechanisms through which natural environments may promote mental health are numerous and diverse. This study aimed to explore 1) the potential associations of socioeconomic variables (SES and maternal education attainment) with mental health scores and residential greenness, blueness and NO2 metrics, and, 2) the association between greenness and blueness metrics and mental health scores of children in the Spanish INfancia y Medio Ambiente (INMA) birth cohort at two different time points. The study samples were composed of 1738 six-to eight-year-olds (49% female) and 1449 ten-to twelve-year-olds (living in Asturias, Gipuzkoa, Sabadell and Valencia, Spain. Individual Normalized Difference Vegetation Index (NDVI) values in 100-, 300- and 500-m buffers and availability of green and blue spaces &gt;5000 m2 in 300-m buffers were calculated using Geographic Information Systems software. Residential NO2 values were estimated using land use regression models. Internalizing, externalizing and total problems scores were obtained with the Strengths and Difficulties Questionnaire (SDQ). Linear and logistic mixed-effects models revealed unequal distribution of environmental exposures by SES and maternal education but did not show statistically significant associations between greenness and blueness metrics and mental health indicators. The protective effect of green and blue spaces on children's mental health could not be confirmed in this study and therefore further research is required.</p

Prenatal urban environment and blood pressure trajectories from childhood to early adulthood

Background: Prenatal urban environmental exposures have been associated with blood pressure in children. The dynamic of these associations across childhood and later ages is unknown. Objectives: The purpose of this study was to assess associations of prenatal urban environmental exposures with blood pressure trajectories from childhood to early adulthood. Methods: Repeated measures of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were collected in up to 7,454 participants from a UK birth cohort. Prenatal urban exposures (n = 43) covered measures of noise, air pollution, built environment, natural spaces, traffic, meteorology, and food environment. An exposome-wide association study approach was used. Linear spline mixed-effects models were used to model associations of each exposure with trajectories of blood pressure. Replication was sought in 4 independent European cohorts (up to 9,261). Results: In discovery analyses, higher humidity was associated with a faster increase (mean yearly change in SBP for an interquartile range increase in humidity: 0.29 mm Hg/y, 95% CI: 0.20-0.39) and higher temperature with a slower increase (mean yearly change in SBP per interquartile range increase in temperature: −0.17 mm Hg/y, 95% CI: −0.28 to −0.07) in SBP in childhood. Higher levels of humidity and air pollution were associated with faster increase in DBP in childhood and slower increase in adolescence. There was little evidence of an association of other exposures with change in SBP or DBP. Results for humidity and temperature, but not for air pollution, were replicated in other cohorts. Conclusions: Replicated findings suggest that higher prenatal humidity and temperature could modulate blood pressure changes across childhood.</p

Exposure to natural environments during pregnancy and birth outcomes in 11 European birth cohorts

Research suggests that maternal exposure to natural environments (i.e., green and blue spaces) promotes healthy fetal growth. However, the available evidence is heterogeneous across regions, with very few studies on the effects of blue spaces. This study evaluated associations between maternal exposure to natural environments and birth outcomes in 11 birth cohorts across nine European countries. This study, part of the LifeCycle project, was based on a total sample size of 69,683 newborns with harmonised data. For each participant, we calculated seven indicators of residential exposure to natural environments: surrounding greenspace in 100m, 300m, and 500m using Normalised Difference Vegetation Index (NDVI) buffers, distance to the nearest green space, accessibility to green space, distance to the nearest blue space, and accessibility to blue space. Measures of birth weight and small for gestational age (SGA) were extracted from hospital records. We used pooled linear and logistic regression models to estimate associations between exposure to the natural environment and birth outcomes, controlling for the relevant covariates. We evaluated the potential effect modification by socioeconomic status (SES) and region of Europe and the influence of ambient air pollution on the associations. In the pooled analyses, residential surrounding greenspace in 100m, 300m, and 500m buffer was associated with increased birth weight and lower odds for SGA. Higher residential distance to green space was associated with lower birth weight and higher odds for SGA. We observed close to null associations for accessibility to green space and exposure to blue space. We found stronger estimated magnitudes for those participants with lower educational levels, from more deprived areas, and living in the northern European region. Our associations did not change notably after adjustment for air pollution. These findings may support implementing policies to promote natural environments in our cities, starting in more deprived areas

Five carbon- and nitrogen-bearing species in a hot giant planet's atmosphere

The atmospheres of gaseous giant exoplanets orbiting close to their parent stars (hot Jupiters) have been probed for nearly two decades. They allow us to investigate the chemical and physical properties of planetary atmospheres under extreme irradiation conditions. Previous observations of hot Jupiters as they transit in front of their host stars have revealed the frequent presence of water vapour and carbon monoxide in their atmospheres; this has been studied in terms of scaled solar composition under the usual assumption of chemical equilibrium. Both molecules as well as hydrogen cyanide were found in the atmosphere of HD 209458b, a well studied hot Jupiter (with equilibrium temperature around 1,500 kelvin), whereas ammonia was tentatively detected there and subsequently refuted. Here we report observations of HD 209458b that indicate the presence of water (H2O), carbon monoxide (CO), hydrogen cyanide (HCN), methane (CH4), ammonia (NH3) and acetylene (C2H2), with statistical significance of 5.3 to 9.9 standard deviations per molecule. Atmospheric models in radiative and chemical equilibrium that account for the detected species indicate a carbon-rich chemistry with a carbon-to-oxygen ratio close to or greater than 1, higher than the solar value (0.55). According to existing models relating the atmospheric chemistry to planet formation and migration scenarios, this would suggest that HD 209458b formed far from its present location and subsequently migrated inwards. Other hot Jupiters may also show a richer chemistry than has been previously found, which would bring into question the frequently made assumption that they have solar-like and oxygen-rich compositions.Comment: As part of the Springer Nature Content Sharing Initiative, it is possible to access a view-only version of this paper by using the following SharedIt link: https://rdcu.be/cifr
