Both perspectives were mildly related, correlations were found for "degree" and "information" (r = .31, p < .05), "degree" and "joint work" (r = .38, p < .01), and "reciprocity" and "joint work" (r = .33, p < .05), no correlations were found for "degree" or "reciprocity" and "discussing". At the department level, only mathematics showed significant correlations. Results indicated that, in further research, qualitative aspects as well as quantitative aspects should be included.
