IMPORTANCE of the PEER –REVIEW PROCESS

Elements of the Peer- review in the everyday life of scientist: 

Elements of the Peer- review in the everyday life of scientist 1) submitted research papers are critiqued by peers before publication (3-4 reviewers) 2) citation indexes of every scientists 3) Impact factors of the journals itself 4) seminars and presentations at scientific conferences 5) grant panels

How it is measured? Mostly by citations and by impact factors

Thomson Scientific, formerly known as Thomson ISI : 

Thomson Scientific, formerly known as Thomson ISI ISI provides access to high-value, essential information for researchers and scholars worldwide for over 45 years.

Web of Science: 

Web of Science Web of Science includes: Science Citation Index Expanded, 1900- (SCIE) Social Sciences Citation Index, 1956- (SSCI) Arts & Humanities Citation Index, 1975- (A&HCI) Web of science started in 1961 as Science Citation Index

Science Citation Index: 

Science Citation Index indexing 5900 periodicals; 19 000 new records per week; 423 000 new citations per week; Some of the disciplines covered include: Agriculture;  Astronomy;  Biochemistry; Biology;  Biotechnology;  Chemistry; Computer Science;  Materials Science;  Mathematics;  Medicine;  Neuroscience; Oncology; Pediatrics; Pharmacology; Physics; Plant Sciences; Psychiatry; Surgery; Veterinary Science; Zoology

Journal Citation Reports: 

Journal Citation Reports What journals are most frequently cited? What journals have the highest impact? (most influential); What are the “hottest” journals on the particular field ? What are the largest journals?

Statistic reported by JCR: 

Statistic reported by JCR Article Counts — Shows the number of articles published in a journal in a particular year (original research and review articles only – no letters and commentaries) Impact Factor — On average, how often is each article from a journal cited each year. Looks at previous two years of data. Immediacy Index — How fast is an article cited the same year it is published. How “hot” are the articles?

Statistic reported by JCR: 

Cited Half-Life — When other journals cite this journal, what is the 50% cut-off for how old they cite it? Helps you to evaluate the age of the majority of cited articles published in a journal; Citing Half-Life — When the journal cites other articles, what is the 50% cut-off for how old they are? Helps you evaluate the age of the majority of articles referenced by a Journal; More info: http://thomsonscientific.com/support/products/jcr/ Statistic reported by JCR

CITATION INDEX problems: 

CITATION INDEX problems Is someone citing it because it is good or bad? People can cite themselves (self-citation) or their boss—inflating the numbers Databases cannot cover all types of publications— citation index is not a “true” count. Foreign authors may be cited more in foreign publications—missed citations

Danger of incorrect citations: 

Danger of incorrect citations Author mistyped the citation in their paper, and WoS just copied what they had; WoS employees entered the citation incorrectly; The citation has been perpetuated incorrectly as it has passed from paper to paper (that usually means that authors are citing something that they never read themselves)

Tips to find an author by its name : 

Tips to find an author by its name Names of more than one word, type all possibilities O CONNOR or OCONNOR Chinese names : combine the three components in all possible ways; If there are more than one initial, try one inial and two initials; (e.g. Baranova AV and Baranova A – the same person)

SCIENTIFIC RANKINGS :WHO IS COOLER? : 

SCIENTIFIC RANKINGS : WHO IS COOLER? H-Index aimed for fair ranking of scientists : Invented by Jorge Hirsch, a physicist at the University of California, San Diego h-index = highest number of papers a scientist has that have each received at least that number of citations H= 50; meaning that researcher has 50 papers, each of them cited 50 times

Example of H rank calculation: : 

Example of H rank calculation: Paper 1 cited 3 times Paper 2 cited 8 times Paper 3 cited 4 times Paper 4 cited 0 times Paper 5 cited 13 times Paper 6 cited 3 times RANK = 5 Paper 7 cited 2 times Paper 8 cited 12 times Paper 9 cited 85 times Paper 10 cited 0 times Paper 11 cited 8 times

Some of the highest-ranked physicists, by h-index : 

Some of the highest-ranked physicists, by h-index 110 Ed Witten Princeton Institute for Advanced Study. Devised M theory. 94 Marvin Cohen University of California, Berkeley. Condensed-matter theorist. 91 Philip Anderson Princeton University. Condensed-matter theorist, won Nobel prize in 1977. 86 Manuel Cardona Max Planck Institute for Solid State Research. Works on superconductors. 79 Pierre-Gilles de Gennes ESPCI, Paris. Condensed-matter theorist, won Nobel prize in 1991. 68 Frank Wilczek Massachusetts Institute of Technology. Won Nobel prize in 2004 for work on the strong force. 66 David Gross Kavli Institute for Theoretical Physics, Santa Barbara. Won 2004 Nobel prize with Wilczek.

Potential difficulties with H-method: 

Potential difficulties with H-method Different disciplines have different citation patterns, so each field would need different thresholds. Biologists can have h values of up to 190. With that proviso, the method should work across disciplines.

INTERFACE LOOKS A BIT DIFFERENT

If you want to find a review (non-experimental papers): 

If you want to find a review (non-experimental papers) TYPE “REVIEW” in the search line. e.g. “obesity hypertension review” Or “deafness connexin review” In such case you will get only the papers with most generalized content

If you want to find not a papers but Journals (e.g. all journals accepting papers on obesity):
