In a classic book, Unobtrusive Measures, first published in 1966, Eugene Webb, Donald Campbell, Richard Schwartz, and Lee Sechrest made a case for the greater use of data sources not dependent on the elicitation of data directly from respondents or informants. They further argued for the importance of combining data obtained using different methods in ways that allowed the methodological weaknesses inherent in particular methods to compensate for one another. The various sources of potential ...

Synthesis, properties, and application in catalysis of Cu, Ni, Co, Zn ferrites: A comprehensive review study

Ferrites, especially CuFe2O4, NiFe2O4, CoFe2O4, and ZnFe2O4, have gained significant attention due to their unique magnetic, chemical/crystal stability, and catalytic properties, making them promising materials for a wide range of applications, particularly in the field of catalysis. This review provides a comprehensive overview of the principal synthesis methods employed to obtain ferrites in a green and sustainable way, emphasising how variations in the synthesis conditions affect their phy...

Learning to use/through the use of ChatGPT: the AI literacies of Italian students.

As with other new technologies, children and young people have been eager early adopters of Generative AI tools since the release of ChatGPT in November 2022. Research worldwide has documented the most common uses of GenAI tools among this age group, as well as their expectations and fears for the future.
