Assignments

• Assignment 1:
  a. Among the networks (description) from the following list:
  1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17
  download the network with your number (in the list of students), read it in Pajek and draw it 'nicely'.
  b. Transform the Moreno's sociogram with your number from the following list:
  1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17
  into Pajek's network data format. Using Pajek draw it to resemble the Moreno's picture.
  Info about Moreno's sociograms: keys, 1, 2, S1, S2.
  Both pictures and the Pajek's net file for your sociogram send to Nataša (natasa.kejzar@fdv.uni-lj.si) till Wednesday, July 25 before the lectures.
• Assignment 2:
  a. for 'your' network determine and draw the female/male subnetwork; determine the vertices with largest in/out/all-degree; determine initial/terminal/isolated vertices.
  b. in the S&K network: select a continent (not North America or Oceania), extract the subnetwork of countries belonging to it, draw it; draw it in the context of other continents. Select two continents. Extract and draw the subnetwork of lines between these two continents.
  Send the results to Nataša till Thursday, July 26 before the lectures.
• Assignment 3:
  a. apply the connectivity concepts to 'your' network. For example: determine strong/weak components, ...
  b. apply the connectivity concepts to relations from the WordNet network (doc).
  Send the results to Nataša till Friday, July 27 before the lectures.
• Assignment 4:
  a. apply the centrality concepts to 'your' network.
  b. search for patterns in a genealogy Royal or Ragusa. The genealogical macros are in Genea (ZIP) and the marriage patterns are in Frag16 (PAJ).
  Send the results to Nataša till Monday, July 30 before the lectures.
• Assignment 5:
  a. apply the cohesion concepts to 'your' network.
  b. determine interesting subnetworks (cores, islands) in the Edinburgh Associative Thesaurus.
  Send the results to Nataša till Tuesday, July 31 before the lectures.
• Assignment 6:
  a. analyze the two mode network They rule.
  Send the results to Nataša till Wednesday, August 1 before the lectures.
• Assignment 7:
  a. analyze 'your' network using clustering and blockmodeling.
  b. analyze S&K network using prespecified center-periphery block model.
  Send the results to Nataša till Thursday, August 2 before the lectures.
• Assignment 8:
  a. From the Web of Science (or ISI from IZUM) save the descriptions of papers (more than 500) on selected topic and using the program WoS2Pajek convert them into Pajek's files. Analyze these files. For details see the WoS2Pajek manual.
  Send the results to Nataša till Friday, August 3 before the lectures.
  b. Fill the ECPR Summer School Evaluation Survey.
