What is scientific dishonesty?

“Aarhus University subscribes to the recommendations in the Danish Code of Conduct for Research Integrity and the DCSC’s definition of research misconduct and other violations of responsible conduct of research: 

• Research misconduct
  The central phenomena are fabrication, falsification and plagiarism, and other serious breaches of responsible conduct of research, committed deliberately or by gross negligence.
• Questionable conduct of research
  This includes actions representing violations of responsible conduct of research, but which cannot be classified as misconduct.”

Excerpt from the guidelines for responsible conduct of research at Aarhus University.
