Interdisciplinarity as Diversity in Citation Patterns among Journals:

Rao-Stirling Diversity, Relative Variety, and the Gini coefficient

 

Loet Leydesdorff,*^[1] Caroline S. Wagner,^[2] and Lutz Bornmann^[3] 

 

The program mode2div.exe (at http://www.leydesdorff.net/software/mode2div/mode2div.exe ) computes diversity measures along the column vectors of a 2-mode matrix saved in the .net format of Pajek. (Use preferentially Pajek itself for the saving.) The program and the data file have to be in the same folder. One is first prompted for the name of the file with the data.

 

If the matrix is 1-mode, use the following instruction in Pajek: Network > Create New Network> Transform> 1-Mode to 2-Mode. Save the file as a 2-mode matrix.

 

Additionally, one needs a file <coocc.net> made in Pajek. One can generate this file using the 2-mode file in Pajek as follows: Network > 2-Mode Network > 2-Mode to 1-Mode > Rows. Save the resulting file as coocc.net. (Obligatory file name; the file needs to be in the same folder.)

 

Output is the file div_col.dbf containing the various diversity indicators along the column dimension for all units of analysis (in the rows). (One can transpose the data matrix in Pajek:  Network > Create New Network > Transform > Transpose.  Thereafter, coocc.net has also to be replaced.) Note that previous versions of the output  file (“div_col.dbf”) are overwritten during subsequent runs.
