     Motivated by the Arzel\`a-Ascoli theorem for ${\displaystyle C^{b}(X,E)}$, where ${\displaystyle X}$ is an^[sic] Euclidean space and ${\displaystyle E}$ an arbitrary Banach space, we construct a quasimeasure for this space and study its properties.

2. An imprecise means of measuring something.

     Performative regimes (see Power, 1997, 2004; Strathern, 2000) in many countries now judge the worth of an academic by the number of their publications, or through some quasimeasure of quality such as download data or citations for the paper.
