In marine structural engineering, the impact resistance of concrete holds high significance. The determination whether combined use expansion agent (EA) and glass fiber (GF) has a synergistic effect on seawater–sea-sand (SSC) plays role in its performance application. this study, dynamic Brazilian disc test at various strain rates was carried out with an SHPB device to investigate mixing 0% 6% EA 1% GF splitting tensile properties SSC. results show that rate GF-reinforced SSC during tests higher rates, indicating strong sensitivity. reinforcement consumed more energy under loading, thus maintaining morphological integrity concrete. However, strength obtained had significant overload which cannot be ignored. doped showed enhancement SSC’s properties.

Complex pathways from nature relatedness and knowledge to pro-environmental behavior through eco-emotions

Journal of Cleaner Production, Год журнала: 2024, Номер 468, С. 143037 - 143037

In preventing the collapse of ecosystem, individual behavior plays a crucial role alongside action global actors, but complex possible pathways from nature relatedness and knowledge to pro-environmental (PEB) through eco-emotions have not been widely studied. Thus, current study aimed explore relationship between environmental knowledge, relatedness, different (anxiety, guilt grief), general PEB intention change in future. A representative sample Hungarian population (N = 1000) participated an online answered questions about their behavior, completed Nature Relatedness Scale, Ecological Grief Questionnaire short versions Eco-anxiety Eco-guilt Questionnaire. General was directly associated with higher (β 0.223, SD 0.032), ecological grief 0.252, 0.076) negative consequences anxiety 0.106, 0.044), while 0.190, 0.034), 0.131, 0.032, eco-guilt 0.248, 0.052 less -0.109, 0.055). positively mediated effect on PEB, negatively change. positive mediator By revealing explaining system our article provides useful insights for awareness raising efforts.

From Health Risks to Environmental Actions: Research on the Pathway of Guiding Citizens to Participate in Pocket-Park Governance

Land, Год журнала: 2024, Номер 13(10), С. 1612 - 1612

The COVID-19 pandemic has heightened the demand for urban pocket parks near residential areas, posing new challenges environmental governance. However, there is a lack of research on how to engage citizens in pocket-park governance address both potential and unforeseen risks. This study combines social information processing theory with norm activation model develop framework that identifies shaping stages influencing factors citizens’ intentions participate Using partial least squares structural equation modeling, this analyzed relationships among external factors, attitudes, moral norms, based 719 responses from an online survey targeting Chinese November December 2023. Results indicate health risks quality positively affect perceived usefulness. Attitudes norms are indeed important mediating positive effect environment intention participate. pathway guiding clarified, which helps bolster resilience green spaces improve life residents after public crises.
