Hi everyone.? I'm working through a paper using MRQAP and am running into some issues finding published SNA papers that use MRQAP in empirical examples.? There are several papers walking through the nuts and bolts of QAP, but I'm looking for a more applied example.? If you know of any citations I would be grateful if you'd send them along.?


Particularly, I'm looking for guidance to know what to control for the in the analysis.? I have my key predictor, but I'm not completely sure what I should include as controls from a networks perspective.


Thanks in advance for any help.

Bryce

How to keep duplicate ties for dyads when importing via DL editor?

 

Hi there, Ucinet friends.?


I have encountered a problem and I can't seem to find the solution anywhere. I hope you experts can help me.


So, I have a csv?file with dyads, years, and values. Like this:


Person1 Person2 Year Val1 Val2 ...

---------------------------------------------------------

Sarah Steve 2013 ...................

Sarah Steve 2014 ...................

Sarah James 2013 ...................

Sarah James 2014 ...................

Steve James 2013 ...................

Steve James 2014 ...................


Where Val2 and Val2 will vary across years.?What I want to do is to import this dataset to Ucinet but keep all the dyads-year instances (what I will later do is to run QAP regression analyses with year fixed effects), so that the ensuing matrices (for each variable) will contain every observation. What I have tried with so far is to import the dataset via the DL editor and set the data format to "edgearray1" and tick "Duplicate ties: Ignore". However, this generates the same output as when I tick?"Duplicate ties: Sum/count up". That is, it makes a dyad appear only once in a matrix and its associated score on any variable is the sum. This is not what I want.


I hope there is someone out there willing to help a not-so-advanced Ucinet user with his problems.?


Best, Niels?

Re: Papers using MRQAP

 

Hi Bryce,?

Not sure what you're asking for, but I've used MRQAP quite a bit in the organizational realm. Here are some?examples:

Grosser, T. J., Lopez-Kidwell, V., & Labianca, G. (2010). A social network analysis of positive and negative gossip in organizational life.?Group & Organization Management,?35(2), 177-212.?

Marineau, J. E., Hood, A., & Labianca, G. (2017). Multiplex conflict: Examining the effects of overlapping work-related and personal-based conflict on advice-seeking in organizations.?Journal of Business and Psychology.

Umphress, E. E., Labianca, G., Brass, D. J., Kass, E., & Scholten, L. (2003). The role of instrumental and expressive social ties in employees' perceptions of organizational justice.?Organization science,?14(6), 738-753.?

Hope that helps,

Joe

Re: Keyplayer: Can't upload my network data!

Dear Steve,

I appreciate your answer and your support very much, thank you!?

I'm using Keyplayer 1, and it is interesting that when I upload?sample dataset ?"methodscamp", Keyplayer is working perfectly, but If I save the same file in my UCINET software, I can't run it, same as I can't run my own network data.?
I've been trying to solve the issue, tried out many combinations, but at the end, I've just typed in by hand the nodelist formats and uploaded the text files. It works perfectly with that text files, and I'm lucky because I have relatively small networks so I could go this way.?

While I have you on the line, I'd like to thank you for all your research and for your great book "Analysing Social Networks", it has been inspiring and important to me throughout my PhD. I'm doing research in how the (environmental) knowledge flows through the urban governance networks, and couldn't do it without knowledge I've learned form your work.?

Many greetings form Technical University Vienna!

It depends on which keyplayer player program you are running. The one that has the fancy rotating logo (keyplayer 2) only reads vna files. If that’s what you are using, feel free to send me your data and I will convert it (steve.borgatti@...). The program looks like this:

Keyplayer 1, on the other hand, reads ucinet files. If you are having trouble with that, well, I guess the answer is the same: send me the data.

dealing with duplicate nodes

 

Hello,


I have a large co-authorship data set with about 1400 authors of about 350 papers. Now I would like to look at the affiliations/organization of the authors, which ones collaborate with each other, etc.?


I have replaced the author names with their affiliations and sorted alphabetically, but then I come out with lots of duplicates that have to be summed (see excerpt of the data below). Does anyone have ideas about how to do this most efficiently? And also how to deal with diagonal values (intra-organization collaboration) in the analysis??


Thanks!

Noora?

attribute network/dealing with duplicate nodes

 

Hi all,


I have a co-authorship dataset with about 1400 authors who have written about 350 papers (all papers on nutrition in West Africa over 10 years). One of the attributes of the authors is their affiliation/organization and I would like to now see which organizations are collaborating with each other. I can easily replace the author names with their corresponding organization and sort alphabetically, but I end up with lots of duplicate nodes that need to be summed (a small sample of the data is below).?


Any ideas on an easier way to transform this data from author links to organization links???


Also, how do you deal with the many diagonal values in the analysis? (lots of collaboration within organizations...)


Thanks!

Well, you need to invest some time with the program.

You can figure many of these meaures by going to "Network" and reviewing the various submenu options.

You can also look some of these up using the help menu.

You can also review the Bogatti, Everett and Johnson 2018 book, or the online Hanneman tutorial.

Doctoral Student Positions at the University of Kentucky -- Feb 1 deadline

 

开云体育

The Department of Management at the University of Kentucky is looking for bright, inquisitive individuals to join our PhD Program in the Fall, 2019.

?

Our Program

?

We have a highly collaborative faculty and maintain a small doctoral program in order to ensure significant interactions between our students and faculty. Our program prepares graduates to be marketable for tenure-track positions in reputable research institutions as well as for long-term career success (recent alumni have published in outlets such as the Academy of Management Journal, Organization Science, Journal of Applied Psychology, Journal of Management, Academy of Management Annals, and Human Resource Management).

?

Our doctoral students receive a competitive stipend and a full tuition waiver for up to five years. We also provide generous resources for regular attendance at academic conferences. Students in our doctoral program typically do not teach until their third year and then only once per academic year in order to gain marketable teaching experience while focusing on coursework and research. More information about our program can be found at

?

Our Department

?

The department is home to the LINKS Center, the preeminent center for the study of social networks in organizations. As a result, in addition to traditional PhD coursework, doctoral students in our program develop expertise in network methods and theory via two seminar courses, a guest speaker program, hosting an annual workshop, and hosting a bi-annual small conference that attracts many of the top faculty in social network analysis from around the world. More information about the LINKS Center can be found at .

?

Our more micro-oriented faculty members (Steve Borgatti, Dan Brass, Eric Gladstone, Joe Labianca, Huiwen Lian, Ajay Mehra, Scott Soltis) conduct research in areas such as career trajectories and networks, conflict (with email content analysis), counterproductive workplace behaviors, creativity and innovation, culture and networks, the effects of social media on collaboration, gender parity, HR attributions, leadership, network experiments on cognition/perception, person-environment fit, power/influence/politics, redundant network ties, and social resource management, among other topics.

?

Our more macro-oriented faculty members (Wally Ferrier, Eric Gladstone, Dan Halgin, Zhi Huang, Ji Youn Kim, Joe Labianca, Ajay Mehra) conduct research in areas such as competitive behavior and competitive forbearance, betrayal and guilt (in macro contexts), knowledge transfer, new venture growth, organization design, organizational status, social cognition, strategic contagion/diffusion, and TMT decision making, among other topics.

?

Our faculty are well-regarded within the organizational research community, as evidenced by having over 85,000 citations, organizing recurring conferences and workshops, and by serving as editors and on the editorial boards of journals such as Administrative Science Quarterly, Academy of Management Journal, Academy of Management Review, Journal of Applied Psychology, Journal of Management, Organization Science, Strategic Organization, and Personnel Psychology.

?

Applications and Inquiries

?

We are reviewing applications on a rolling basis, but the final?deadline for applications is Feb. 1st, 2019. Inquiries about our program can be directed to Scott Soltis: smsolt2@...

error message: add 205091D0

 

Hi, I got the attached error message when I conducted K-core analysis in UCINET. The analysis can be conducted in netdraw. Is that due to my computer (such as not enough memory) or other causes? (Sorry if the issue has been asked in the group.) Thanks.

Re: Two networks compare

 

Good day

I tried to use the CLI command for comparing centralization
cd = centdiff(padgm padgb undir)

But I keep getting the same error message that the program cannot open the AppData/Roaming/AnalyticTech Folder.

Does this mean I need to change the directory folder or reinstall the software?

Any assistance would be appreciated.

Best regards
Rhoda


comparing networks of different sizes

 

Good day


Previously the literature indicated that network characteristics could not be compared for networks of different sizes. However, UCINET 6.666 now offers the facility to compare networks. Can this facility be used for networks of different sizes or only for comparing networks of the same size??


Best regards

Rhoda


Comparing networks

 

Good day

I saw that the UCINET 6.666 software has the facility to compare network characteristics however, previous literature indicated that networks of different sizes could not be compared. Does this new facility compare networks of the same size or different sizes? Thank you in advance for the clarification.

Best regards

Structural Equivalence for large networks

 

Hi,

Can structural equivalence in UCINET run on a network of 800000 nodes? If yes, what is the average time to do that on 16 GB windows desktop?

Thank you
Best regards,
Deena

Re: Convert attribute to matrix

Thanks for the scenarios — I follow what you are outlining — and thank you. I do not have directed networks. The dependent variable is time spent as association between individual lizards. Independent variables are all continuous, such as how close retreats are from each other or difference in mass or personality measures (cm flight initiation distance).?

It seems that you could covert all to rank values and then matrify— but again, not sure when/why you’d choose to look at absolute difference vs. other metrics.?

Thanks for your patience — just trying to understand!?

That’s a very broad question. Here are a couple a couple of illustrative responses.

?

Suppose you have a categorical attribute such as gender, coded 1=female, 0=male.

?

In Attribute to matrix, if you choose exact matches, you will create a matrix X such that Xij = 1 if the I and J are the same gender, and Xij = 0 if I and J are different genders. Now suppose you correlate this with a matrix F in which Fij = 1 if I is friends with J, and zero otherwise. If the correlation is positive, that means that big numbers Xij (“big” meaning 1) tend to occur when Fij is big (i.e., 1) and when Xij is small (0), Fij tends to be small (0). In other words, a positive correlation would indicate that friendships tend to be between people of the same gender.

?

If you choose sender effects, you create a matrix such that Xij = gender of I. If you then correlated this with friendship, a positive correlation would indicate that when Xij is large (1), friendship tends to be large (1) and when Xij is small (0), friendship tends to be small (0). That means a friendship tie from I to J is more likely when I is female. In short, women have more outgoing ties than men.

?

Suppose you have a continuous attribute such as age. And a network such as seeks advice from, as in Aij = 1 if I seeks advice from J and Aij = 0 if I does not seek advice from J.

?

If you choose difference, you create a matrix X in which Xij = Age(i) – Age(j). So if you correlate with Advice, a positive correlation would occur if, when Xij is large (I older than J), advice tends to be large (1), and when Xij is negative (J older than I), advice tends to be small (0). A positive correlation would mean that older people tend to ask advice of younger people (e.g., which mobile phone should I buy?)

When converting attribute to matrix data, can anyone explain/point me to resource about when you would use each similarity metric and why? Thanks in advance,
