Here is a link of Stefano Parenti's paper "The Cathedral Rite of Constantinople: Evolution of a Local Tradition":
https://www.academia.edu/2164351/The_Cathedral_Rite_of_Constantinople_Evolution_of_a_Local_Tradition
Its main conclusion can be summarised in author's own words as follows: "This article studies the evolution of the Liturgy of the Hours at Constantinople after the ninth century, when not only the monastic churches of the city, but also secular churches followed the liturgical tradition referred to as "hagiopolitis". Only the Cathedral was left using the rite appropriately called "ekklisiastis". The article also analyses particular forms of "bi-ritualism" between these two liturgical systems, with the tendency to conserve the "ekklisiastis" rite during the most important times of the liturgical year. Contrary to what was previously believed on the subject, the eleventh century was not the zenith of the cathedral tradition of Constantinople, but rather an age of decadence and abandonment".
Thank You for the information. In my opinion it will be helpful for the persons who are interesting on Asmatic Liturgy of the Hours to see also the « S. PARENTI, «Towards a Regional History of the Byzantine Euchology of the Sacraments» Eor 27 (2010), 109-121»•[
