Paragraph of academic text

Jello helpers,

I'd really appreciate if you could comment on my text. I am writing a research proposal and describing my field of study.

*** ***

I am a Cold War researcher specializing in the Eastern European perspective. In this study, interactivity is explored from three dimensions: (1) The investigation of multi-level interaction provides a new interpretation about the communication channels and the vertical flow of information from the top decision-makers down to the grass-roots level of society and vice versa. (2) The study of multi-sphere interaction reveals the horizontal inter-connectivity of different social, cultural, political and economic areas and their actors. (3) The analysis of East-West interaction highlights the effects of Western ideas on the above mentioned vertical and horizontal interactivity inside the system. The scale of interactivity on different levels indicated varieties of institutional change. I choose cases (from the culture industry, service sector, agricultural sphere, trade) of which none have been previously explored in this complexity.

**Or alternative last sentence**

My cases (ranging from the culture industry, service sector, agricultural sphere, trade) have never been previously explored in this complexity.
