ABSTRACT
Introduction: As it is stated by researchers from multiple scientific fields, climate change has real consequences both for the natural environment but also for the human beings, but not everyone is interested in fighting the global warming and its implications. Yet, there are people who are curious about climate change and became invested in the cause of fighting it. Taking this into account, the aim of this study was to create a questionnaire that would enable to measure curiosity about climate change and as such be an useful tool in research regarding this matter. Methods: After examination of existing literature and the evaluation of competent judges, we created a questionnaire which structure and reliability was determined in conducted studies. We also investigated possible correlations between introduced in this paper the Curiosity of Climate Changes Scale (CCCS) and other diagnostic tools: The Curiosity and Exploration Inventory II, The Need for Cognitive Closure Scale, The Elements of Nature Curiosity Scale, The Climate Anxiety Scale, The Environmental Identity Scale and The Generational Time Perspective Scale. Results: The results of the factor analyses verified a one-factor structure. The CCCS showed satisfactory internal consistency (Cronbach's α = 0.95). The validity of the CCCS was indicated by correlations with different scales. The CCCS correlates with general curiosity, curiosity of elements of nature, need for cognitive closure, environmental identity, climate anxiety and generational time perspective. Conclusion: The results indicate that the Curiosity of Climate Changes Scale is a valid and reliable tool. The Curiosity of Climate Changes Scale can be used in future research but also has its practical use - for teachers and environmental educators who thanks to the CCCS can obtain information regarding one's interest in climate change, which can be used in educational programs.
ABSTRACT
Complex morphologies in lipid membranes typically arise due to chemical heterogeneity, but in the tilted gel phase, complex shapes can form spontaneously even in a membrane containing only a single lipid component. We explore this phenomenon via experiments and coarse-grained simulations on giant unilamellar vesicles of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine. When cooled from the untilted L(α) liquid-crystalline phase into the tilted gel phase, vesicles deform from smooth spheres to disordered, highly crumpled shapes. We propose that this shape evolution is driven by nucleation of complex membrane microstructure with topological defects in the tilt orientation that induce nonuniform membrane curvature. Coarse-grained simulations demonstrate this mechanism and show that kinetic competition between curvature change and defect motion can trap vesicles in deeply metastable, defect-rich structures.
