Scientific Publishing and Values in the Academy • Disclaimer: a single perspective • Authorship and the dreaded “middle” position • Lessons from the world of physics • Metrics of impact • Networks and Citation • Shift in culture: career advancement • Challenges
Authorship and the dreaded “middle” position • First and Last (senior) authorship • Paradigm shift: small to large scale biomedical research • Lessons from physics • Opportunities for online publishing: delineation of contributions • A solution
Lessons from the world of physics • Physics: • necessity for collaboration • Multi-institutional, international efforts • Invention of the WWW: • Sir Tim Berners-Lee • Biomedicine: • Rewarding individual creative achievements • The academy acceptance of “high-impact, exclusive” journals • Bayh-Dole Act: protection of IP • Saviour?: Shift from small to large-scale science: genome
Opportunities for online publishing: delineation of contributions • A menu of contributions • Design study; Execute study; Data interpretation; ….etc. • Each author is linked to specific contributions • Websites allow for assessment of contributions • Scoring systems are likely to be artificial and contentious

Impact Journals: the Academic Ladder Promotion Promotion Promotion Publications Grants Committee Study Section Academic Honors
Study Sections and Promotion Committees • Study section: • Track record and weight of high-impact work • High-impact: journal types vs citations • More forgiving – reward innovative ideas • Promotions: • Publications given heaviest weight • Testimonials from colleagues • Other factors
Perspective of a Honorary Society (ASCI) Past-President • Selection of inductees • Highest (virtually only) weight • “General” journals vs. “specialty” journals • Theme • Scholarship & Authority • Public impact – difficult to assess for basic research
Plight of a biomedical faculty • Not simply “publish or perish” • Publish in top-tier journals or perish • Cell, JCI, Nature, NEJM, PNAS, Science,… • The Grant-Publication cycle • Visibility and Impact • Promotion
Metrics of impact: popularity • Citation index • Citation and Networks • The “rich gets richer” effect • The GOOGLE effect
Networks and the Small World Effect • Six degrees of separation • How is it possible? • Networks: random versus scale-free • Citations

Poisson distribution Power - law distribution Exponential Network Scale - free Network Natural self-organizing networks are scale-free with nodes and links following a power-law function (from Barabasi; http://www.nd.edu/~networks/papers.htm)

Scale-free model P(k) ~k-3 • GROWTH:At every timestep we add a new node with m edges (connected to the nodes already present in the system). • (2)PREFERENTIAL ATTACHMENT :The probability Π that a new node will be connected to node i depends on the connectivity ki of that node A.-L.Barabási, R.

Open Access: Shift in culture & career advancement • PLoS: grassroots by the elite pack • PMC/BMC: the GOOGLE effect and networks? • How to create the GOOGLE effect? • Quality • Visibility • Accessibility • Speed
Challenges • GOOGLE effect: speed, quality • Culture shift: Promotions Committees • Spread the gospel about OA • Participation in OA by “Hub” investigators • Cost: shifting costs • OA journals without speed and have previous biases are unattractive
