When does an academic information need stimulate a school-inspired information want?

This paper explores the nature of school-inspired information wants. It considers how such wants arise and actions taken by youngsters to meet them. The methodology within the study reported was one of interpretivist ethnography, with data collected from two classes of 7- to 8-year-olds in an English primary school via a form of participant observation that incorporated dialogues with pupils and staff. Children were seen to follow up on topics taught in the classroom with their own questions when one or more of seven situations arose. These included instances in which they developed an empathic interest in the protagonists being studied and when they noted inconsistencies in their own understanding. The findings have a range of implications, notably for practices in both education and LIS

Synthesis and photovoltaic applications of a 4,4′- spirobi[cyclopenta[2,1-b;3,4-b′]dithiophene]-bridged donor/acceptor dye

A new donor/acceptor (D-A) spiro dye (SCPDT1) featuring two bithiophene units, connected through an sp3-hybridized carbon atom, was prepared by a multistep synthetic sequence involving the convenient assembly of the spiro system under mild catalytic conditions. The photocurrent spectrum of dye-sensitized solar cells incorporating SCPDT1 covers the spectral region ranging from 350 to 700 nm and reaches a wide maximum of ∼80% in the 420-560 nm range. Power conversion efficiencies of up to 6.02% were obtained.Fil: Pozzi, Gianluca. Consiglio Nazionale delle Ricerche; ItaliaFil: Orlandi, Simonetta.
