II Evaluating Literature • A. The purpose of the assignment is • to familiarize the student with the processes of researching literature, scanning material to determine relevance, and determining the standing of authors, and The beginning of knowledge is the discovery of something we do not understand. Frank Herbert (1920 - 1986)
The Scientific Community • New ideas evaluated at meeting / symposium* of peers Publication of proceedings or transactions in journals Quality evaluation by peer review • World-wide standard • Conferences an enterprise: airplane ticket paper Selection process sifting process to fit programme No opinion expressed on quality of the paper Conference proceedings not archival • Value of symposium attendance Measure of research output is journal articles “Research outputs” as “receipt” • *symposion, a drinking party; sympinien, to drink
Conference Proceedings, Journals .. • Conference Papers often not reviewed; editorial committee & session chairmen do allocation. • Individual scientist to ensure that they do not make complete fools of themselves in front of the scientific community.

Conference Proceedings, Journals .. • Conference Papers often not reviewed; editorial committee & session chairmen do allocation. • Individual scientist to ensure that they do not make complete fools of themselves in front of the scientific community. • (Royal Society Fellows published without review; Oliver Heaviside and Lord Kelvin; all Fellows subsequently reviewed) • Rapid dissemination of results • Journals editorial boards of eminent scientists; review committees and policy; citation lists. • Conference papers followed by Journal publications; material now widely electronically available. • Archival
.. and Books • What do we find in Text Books? • They collect and organize the relevant body of • science in orderly fashion, unifying work over • extended period of time • Textbooks lag the forefront of development • Textbooks provide basis for development • Classic textbooks basic principles relevant for many decades Antennas by Sam Silver, published 50 years ago as part of the MIT Radiation Lab Series, is still being reprinted.

The Impact Factor • The impact factor for a journal is calculated based on a three-year period; • can be considered to be the average number of times published papers are cited up to two years after publication. For example, the impact factor 2010 for a journal would be calculated as follows: A = the number of times articles published in 2008-9 were cited in indexed journals during 2010B = the number of articles, reviews, proceedings or notes published in 2008-9 impact factor 2010 = A/B
Eigenfactor & Article Influence • The Eigenfactor score of a Journal is a measure of the total importance of a journal to the scientific community. • With all else equal, the Eigenfactor score of a journal doubles when it doubles in size. Thus a very large journal such as the Journal of Biological Chemistry which publishes more than 6,000 articles annually, will have extremely high Eigenfactor scores simply based upon its size. • Eigenfactor scores are scaled so that the sum of the Eigenfactor scores of all journals listed in Thomson’s Journal Citation Reports (JCR) is 100.
Eigenfactor & Article Influence • The Article Influence score of a journal is a measure of the average influence of each of its articles over the first five years after publication. • Article Influence measures the average influence, per article, of the papers in a journal. As such, it is comparable to Thomson Scientific’s widely-used Impact Factor. • Article Influence scores are normalized so that the mean article in the entire Thomson Journal Citation Reports (JCR) database has an article influence of 1.00.
