This study examines the determinants of green purchase behavior (GPB) among young consumers in a digital context by integrating drive for environmental responsibility (DER), social media attachment (SMA), green product knowledge (GPK), and green consumption values (GCV) within the Theory of Reciprocal Determinism (TRD). In addition, it investigates the moderating role of SMA in the relationship between DER and GPB, as well as the role of attitude in the link between GCV and GPB. Survey data from 285 participants aged 18 to 30 collected using a non-probability sampling method. Partial Least Squares Structural Equation Modeling (PLS-SEM) were utilized in the study. The findings reveal that DER, SMA, GPK, and GCV positively influence GPB. However, the moderating effects of SMA and attitude are not supported, indicating that these factors act as independent predictors rather than conditional influencers of GPB. These results provide theoretical insights into the stability of behavioral drivers and reinforce the importance of cognitive and environmental determinants within the TRD framework, even without significant interaction effects. The findings emphasize the significance of individual DER, digital engagement, GPK, and values among urbanized and digitally connected youth, promoting GPB in the digital era. The research offers an original contribution by integrating DER and SMA within the TRD framework in the context of Malaysian digital sustainability. It extends green consumption beyond the Western perspective and provides novel empirical evidence from an emerging economy. The study highlights the theoretical, practical, and policy implications of these findings.
Amphibole in peridotite xenoliths in Cenozoic volcanic rocks of the Massif Central, France, is generally sparse but widely distributed. Here, we discuss its origin in the xenolith suite of Marais de Limagne (Devès volcanic field) and its bearing on evolution of lithospheric mantle in the southern part of the Massif Central. The xenoliths are lherzolites containing (1) no amphibole, (2) 2–5 vol.
Planning education in Poland has developed within a fragmented institutional setting, creating uncertainty about where design-related competences belong and how they are taught. This paper verifies the place of urban design-focused training within planning programmes by examining how curricula and learning outcomes frame graduates’ capacity to make informed decisions on the built environment. Using a framework that integrates contextual, systemic, and pedagogical challenges, the study combines a quantitative review of 28 university programmes, curriculum analysis, and insights from exploratory expert interviews. The findings show a structural mismatch in the classification of planning as a scientific field, a marginal presence of design-oriented content, and weak alignment between intended learning outcomes and their actual delivery, largely due to acute staffing shortages. The study provides new insight into planning education in Central Europe and helps clarify the evolving role and disciplinary boundaries of design within planning training.
Cartan geometry provides a unifying algebraic construction of curvature and torsion, based on an underlying model Lie algebra; a viewpoint that can be extended naturally to the higher algebraic structures underlying supergravity. We present a Cartan-geometric framework for generalized geometries governed by a differential graded Lie algebra, extending previous results. The extended tangent bundle admits the action of both a global duality group Cam and a local gauge group H. This algebraic structure is implemented via a brane current algebra; the phase space Poisson structure of p-branes. Within this Cartan-inspired framework, we define a hierarchy of generalized connections and compute their linearized torsion and curvature tensors, including the higher curvatures required by the tensor hierarchy. This provides a systematic construction of curvature and torsion tensors in generic generalized geometries.
Global ecosystems are rapidly changing under human pressures such as land-use change, degradation, and trace metal pollution. These conditions often favor invasive plants, yet the links between invasiveness and metal contamination remain insufficiently understood. This study aimed to compare the biogeochemical responses of a native species (Tanacetum vulgare) and an invasive species (Solidago gigantea). Specifically, their capacity for metal uptake and translocation was investigated to assess whether certain traits may facilitate the performance of invasive plants in contaminated sites. Concentrations of Cd, Cr, Cu, Pb, Zn, Ni, Fe, and Mn were determined in soils and in the roots and aboveground organs of both species sampled in areas with and without industrial impact. The results showed that both species are capable of inhabiting anthropogenically altered and metal-contaminated sites. Importantly, they both exhibited reduced uptake of metals in polluted soils, indicating the utilization of a metal-excluder strategy. T. vulgare was more likely to restrict metal uptake at the root level, whereas S. gigantea appeared to limit metal translocation to aboveground parts. Moreover, S. gigantea contained significantly lower levels of Cd, Ni, and Pb in its organs than T. vulgare, suggesting greater efficiency in avoiding metal accumulation. These findings support the classification of both species as excluders and highlight the adaptive capacity of invasive species in disturbed environments.
