Variable

Definition (example)

Coding

Partisanship

Is the paper politically conservative (Daily Mail), neutral (BBC), or liberal (The Guardian)?

−1 to 1, with −1 representing liberal (e.g. The Guardian) and 1 representing conservative (e.g. The Daily Mail)

We selected newspaper partisanship based on the ratings of an Oxford study detailing the endorsements that the party makes in general elections (Black and White, 2023) which we cross referenced with YouGov audience ratings by party registration for each source. For example, The Daily Mail both endorses a majority of Conservative candidates in general elections and has a majority of its voters identify as Conservative.

Sentiment

What is the overall sentiment of the article?

Coded −1–1, where −1 is negative, 0 is neutral, and 1 is positive.

Calculated using hand dictionary coding based on the language used in the article. We used manual coding following findings from (Van Atteveldt et al. 2021) that manual coding of media coverage specifically is more reliable than automated or ML coding systems. The author assembled his codebook (specific to coverage of environmental protest in the UK) based on best practices from (Van Atteveldt et al. 2021) and especially (Boukes et al. 2020), who find off-the-shelf sentiment analysis tools wanting and urge the usage of smaller lexicons specialized to the context, language, and domain of the research project at hand. The codebook is available upon request from ES.
