How To

  • Tutorials for using Pajek freeware for network analyis involve reading chapters in the Explorarory Social Network Analysis book about using Pajek, and using the downloadable data files provided with that book. To download, Right click each set of chapter datafiles listed here to SAVE to the directory you select at home or school, but first make subdirectories Ch2, Ch3 etc so each self-extracts to a separate subdirectory and you can find them by chapter. Once saved you can click on each with windows explored and it will self-extract the files for that chapter: chap2.EXE chap3.EXE chap4.EXE chap5.EXE chap6.EXE chap7.EXE chap8.EXE chap9.EXE chap10.EXE chap11.EXE chap12.EXE Appendix.EXE to accompany Exploratory Social Network Analysis with Pajek, by Wouter de Nooy, and pajek authors Andrej Mrvar, and Vladimir Batagelj -- by installing Pajek at home and unzipping datafiles, you can work through the book, turning in exercises and analyses at the rate of two per week for project credit, including a report on and intensive analysis of a dataset.

    --> 3. GIS

    GIS - Geographic Information Systems To load a new data file click /Add Data (Black Cross on Yellow) and find a *.dbf (you can make a dbf from excel through the save formats, but include X Y coordinate data to map such as Latitude and Longitude.

    Once you open, Right click your data table and Display X Y data to make sure that your nodes are coordinated with the map. You may have to click the variables that will be the X,Y coordinates (e.g., Lat and Long). Now an events icon will appear on the left box window (it has a box to check to show/hide).

    Right click the events icon (dbf name next to the check-box) and at the bottom click /Properties then at the top the tab /Symbology and under Show:Quantities/Graduated then select a variable and scale items for size, color that will code your nodes by color and size. This is how you create maps with variables with features defined by node size. If you copy and paste this first property, you can then repeat /Properties and the tab for /Symbology to now display a second (third, etc) variable, for as many different properties as you want. If you have more than one property clicked, however, the larger nodes will override the smaller.

    To show attributes from your database: /Selection/Select by Attributes

    there are dbase files for use with GIS in the c:/My Documents/ArcGis directory:
    SCCS8-8.dbf I would like you to be able to use to map cultural variables from these files, and the codebooks for these ae in two parts and an index below:

    Edit to correct your data (p308): with View/Toolbars click /Editor; Editor button will appear above the window. Click a cell in the data table. Then click the Edit button. To import data: /File/Add Data from Geography Menu

    Clickable links for variables in these databases
    Coded Variables 1-1849
    Index to Variables

    : The numbers in the index refer to those in the titles of the files, e.g., SCCS1-239.dbf

    "SOC SCI 189: Geographic Information Systems for the Social Sciences" Spring 2006 - by Tony Soeller

    I'm teaching a GIS class in Earth System Science this quarter and will be teaching a similar class in Social Sciences next quarter (SS189), so get the word out to your students, please. I've been working with Caesar Sereseres to formulate this class.

    Here's the link to the skeleton web site: for the class mext quarter: http://eee.uci.edu/06s/70680
