5. The Comunity of scientists
“ A Goal of science is to achieve consensus over the widest possible field” The Community of Scientists
Science as a social institution. The goal of science is a consensus of rational opinion over the widest possible field. But there are constraints Education Tradition Sequence of gaining knowledge – existing theories (paradigm) may limit perception The Community of Scientists
Scientific norms Communism Universalism Disinterestedness Originality Skepticism
Communism: scientific knowledge is the property of everyone scientists have to publish their results Scientific norms
Universalism: no privileged sources of scientific knowledge the only criterion is competence Scientific norms
Disinterestedness: refers to a lack of bias or a lack of self-interest is not the same as being uninterested Scientific norms
Originality: work should be original Scientific norms
Skepticism: Scientists are critical Skepticism as peer review Scientific norms
Instruments Invisible colleges Peer review Reward System
Invisible Colleges (communication networks): Journals Conferences Projects … Instruments
Peer Review: independent peers review the paper accept or reject it … almost never a perfect process Instruments
Reward System: Recognition among peers Invited Talks Program Chair of Conferences Community Prizes Top Prizes Salary Contract money Instruments
6. Misconduct in Science
In Science integrity is the most important thing Misconduct in Science Easy to say Hard to do Science punishes misconduct
Scientific Commandments: Be Honest Never manipulate data Be precise Be fair with regard to priority and ideas Be without bias with regard to the data and ideas of your rival Do not make compromises in trying to solve a problem Hans Mohr, 1979 Misconduct in Science
Examples: Fraud Misconduct in Science Fabrication [make up data results] Falsification [change data results]
Plagiarism : use of someone’s else words (ideas, pictures, …) without giving proper credit Misconduct in Science
Conflict of Interest : avoid personal issues Paper of a friend Paper of a competing group
Failing to retain research data for a reasonable period Maintaining inadequate research records Refusing to give peers access to research materials Inappropriate statistic to enhance the significance of research findings Inadequately supervising research subordinates Misrepresenting speculations as fact Releasing results without providing sufficient data Selective reporting of research Interference Self-plagiarism Questionable Research Practices
In Science the Honesty is the key issue… Misconduct in Science … otherwise … … we loose the game badly

1. Research and Scholarship
Research and Scholarship Two dimensions: 1.do research:= Vertical Dimension 2.achieve scholarship:= Horizontal Dimension You must make time for each!!!
Computer Networks Multimedia Communications Software Engineering Knowledge Management Vertical dimension Horizontal dimension Research and Scholarship
New ideas may come from boundary between areas Research and Scholarship
