Main barriers for communication

The main barriers to allow communication processes be developed and improved are, as per the DIALOGUE analyses:

• external factors such as lack of funding, empasis or competition, etc
• career development
• lack of time or money
• economic crisis in the HE environment

Would you think these are easily the only barriers that stop fluid communication? Do you think HEIs could something in order to decrease the impact of these barriers? Do you know of cases that ilustrate the barriers or the improvement of their impact? If so, please share it with this community.
