I am a first year PhD candidate and I study the impact of research and educational policy on the academic relationship. Thank you very much for your help!
Maybe this one will be interesting :Hagenauer, G., & Volet, S. E. (2014). Teacher-student relationship at university: an important yet under-researched field. Oxford Review of Education, 40(3), 370-388. doi: 10.1080/03054985.2014.921613
From a more sociological and organisational point of view, it will be a good place to start :
Enders, J., & Musselin, C. (2008). Back to the future? The academic professions in the 21st century (you can find it in Google scholar).
In the study of impact of research and educational policy on the academic relationship suggested relevant literature in your study are: (1) laws and standards and policies that govern roles, functions, and responsibilities of teachers and students, (2) factors affecting teacher-student academic relationship, (3) effects of teacher-student academic relationship on achievement, learning, and motivation; (4) common issues on teacher-student academic relationship. Good luck.
