Impact factor

Impact factor
Calculation[edit] In any given year, the impact factor of a journal is the average number of citations received per paper published in that journal during the two preceding years.[1] For example, if a journal has an impact factor of 3 in 2008, then its papers published in 2006 and 2007 received 3 citations each on average in 2008. The 2008 impact factor of a journal would be calculated as follows: A = the number of times that articles published in that journal in 2006 and 2007, were cited by articles in indexed journals during 2008. B = the total number of "citable items" published by that journal in 2006 and 2007. 2008 impact factor = A/B. (Note that 2008 impact factors are actually published in 2009; they cannot be calculated until all of the 2008 publications have been processed by the indexing agency.) Use[edit] The impact factor is used to compare different journals within a certain field. Criticisms[edit] Numerous criticisms have been made of the use of an impact factor.

In 1921 Anna Maria, Levi's sister was born; he was to remain close to her all his life. In September 1930 Levi entered the Massimo d'Azeglio Royal Gymnasium a year ahead of normal entrance requirements.[5] In class he was the youngest, the shortest and the cleverest, as well as being the only Jew. In July 1934 at the age of 14, he sat the exams for the Massimo d'Azeglio liceo classico, a Lyceum (sixth form) specialising in the classics, and was admitted that autumn. At the end of the summer he finally passed his Italian exam, and in October he enrolled at the University of Turin, to study chemistry. In July 1938 a group of prominent Italian scientists and intellectuals published the so-called "Manifesto of the Race," a mixture of racial and ideological antisemitic theories from ancient and modern sources.

g-index The g-index is an index for quantifying scientific productivity based on publication record. It was suggested in 2006 by Leo Egghe.[1] The index is calculated based on the distribution of citations received by a given researcher's publications: Given a set of articles ranked in decreasing order of the number of citations that they received, the g-index is the (unique) largest number such that the top g articles received (together) at least g2 citations. Just as with the h-index, the g-index is a number which is the same for two different quantities: g is (1) the number of highly cited articles, such that each of them has brought (2) on average g citations. This is in fact a rewriting of the definition as An example of a g-index (the raw citation data, plotted with stars, allows the h-index to also be extracted for comparison). In other words, this means that in order to have a g-index of n an author that produces n articles should have, on average, n citations for each of them. See also[edit]

You will also need to consider the 'impact factor' of the journal. Journal Impact Factors (JIF) are measured, usually over a year, as the ratio of the number of times papers in that journal are cited (referenced by other authors) divided by the total number of papers published in that journal.

Thus journals with the highest impact factors are generally thought of as being the most prestigious. by raviii Jun 8
