Using keystroke logging to understand writers’ processes on a reading-into-writing test [PDF]

, 2017
Background Integrated reading-into-writing tasks are increasingly used in large-scale language proficiency tests. Such tasks are said to possess higher authenticity as they reflect real-life writing conditions better than independent, writing-only tasks.

Explicit evaluations of log–log integrals

The Journal of Analysis, 2022
AbstractBy investigating a family of log-log type integrals on the unit domain and on the positive half line, we produce a substantial number of new identities, representing the value of the integral with the aid of Euler sums. A new family of Euler sum identities will also be given, thereby extending the current knowledge.
