***** To join INSNA, visit http://www.insna.org ***** Dear all, I am a complete novice in network analysis, and at my very beginning of using UCINET software. I was wandering if anyone could help me with inputting and handling data in the program - namely, I have a longitudinal dataset of some 14000 alliances in a 20 year time span (thus, non-directed ties). The data is in Excel now, and listed in the following manner: Year of alliance partner1 partner2 partner3 and so on 1980 xxx yyy 1980 xxx aaa zzz the problem (or not?) is that in the same data: 1. some companies formed multiple alliances (with different partners) in the same year (so we have them as a special entry, as in the example above 2. some companies have multiple partners in ONE alliance in ONE year, although rare cases; most of them have just one partner per alliance our interest is getting degree centrality (for a start) measures for each company for each year. Could you give me any guidance regarding the best way to input the data into UCINET, and the possibility of using centrality measures (I am not sure if UCINET in the process of creating a matrix would interpret some of the above as missing data, as most of the companies have 1 partner, but I cannot get rid of those having multiple partners. Also, should I perform any matrix transformations or such prior to centrality measures?) another problem is that some of the companies are not only linked to one another via alliances, but also have their own subsidiaries as part of the network data. I believe we should code that somehow as parent-subsidiary ties are important (and stronger!) but I am not sure how to approach that. I know I am full of questions, and probably did not make it clear what exactly the problem is, but if anyone could help me, I could email part of the data for easier communication. Thank you!!!!
