- Ekaterina Damer added an answer:6What are the best crowdsourcing services similar to Amazon Mechanical Turk in Europ?
I would like to use away to use Amazon Mechanical Turk for my own survey application, but it seems It is not possible for those who are not resident of USA or don't have USA credit card.
I found some services such as crowdflower, crowdguru.de, smartsheet which use mturk as a ground layer and built upon it and also some other similar platforms such as Cloudcrowd or Samesource..
However, I am not quite sure which one more suits my goal, and what are the limitations for the tasks that we can put on mturk (if there is any limitation)
I really appreciate all your ideas,
Prolific works such that you insert a survey link in order to start collecting responses (you can find more info here: https://prolificac.zendesk.com/hc/en-us/articles/202820772-How-do-I-post-a-study-on-Prolific-Academic-). We do not provide representative samples as such, but rather randomly chosen sub-samples of all participants that are eligible your study. I'm not entirely sure about the other platforms. Hope this helps :)Following

- Cynthy Haihambo added an answer:47Do you consider how the student interacts with his fellows/teachers/parents/friends as part of the student's Learning Styles?
Studies in Learning Styles are quite different in the way they conceive the scope of Learning Styles. For examples, Coffield et al. (2004) identified 5 families of learning styles:
- constitutionally-based learning styles and preferences
- cognitive structure stable
- stable personality type
- ‘flexibly' stable personality type
- learning approaches and strategies.
In each family, there are many models and inventories to examine student's Learning Styles. Coffield et al. gathered these models which are counted to 71 model. I already studied many of these models but I couldn't find any inventory that consider how the students interact in their social network (real life and online) as part of their learning styles. First, do you know any inventory that include this factor? If not, do you consider this thought worth studying?

As long as education is a one way traffic, we know that we have started the journey but we are far from arriving. But when we start learning from each other in learning settings, irrespective of age, the degrees and title we carry etc, we sure are truly learning! So we need all the bits and pieces from all role players to form the whole we call knowledge.Following

- Valdis Krebs added an answer:13How can I rank nodes in Social networks ?
I have a social network of actors and edges and I want to rank the nodes according to their position in the network . I tried the centrality measure based rankings but looking for a better combination of these centrality measures or any new methods /algorithm to rank these nodes according to their importance and position in the networks
Which centrality measures did you use? Why did you not like them? What are you trying to show?
One measure I like and often use is how many closed triangles does a node belong to? (A is linked to B is linked to C is linked A). This tends to find those nodes in the dense core as mentioned by Edgar above. Another is diversity -- how many links to how many different groups does a node have? These tend to be the boundary spanners.Following

Hello, everyone, now I embark on an new research about the relationship on Twitter. However, I was confused how can I map a large amount of links on one map quickly. I have a 250000*250000 0 or 1sparse matrixI which represents the relationship on Twitter. I tried some software like Gephi, but it is too slow to draw the picture on it and it often fail to work. I tried package igraph on R and it runs a whole night and end up with a picture. However, it is very ugly... Can you give me some advice to deal with it with igraph? or can you recommand some powerful software for me? Thank you very much!
I would use the Netdraw, but after assembly of the network, would select the most central actors to allow a better view. If you are interested in any peripheral region, I recommend using the Zoom tool.Following
- Raman Kumar added an answer:4What is an alternative to a pattern matrix (as in, factor analysis)?
I am supposed to run an empirical research on the attitude towards social media marketing.
The independent variables are: communication, attitude towards social networks in general, average use of SM and the belonging to brand communities as a form of engagement.
The dependent variable is the attitude towards social media advertising.
First I have to run the factor analysis and analyze the pattern matrix, if the variables are good go on with a multiple regression, but with a same bundle of items one of the two doesn't work!! Which means, if I do a linear regression of the dependent variable with the four independent i get a pretty decent R2 adjusted value, but with the same factors i can't seem to get a proper pattern matrix. If instead, i leave out a factor I get a perfect pattern matrix, but then the R2 value is inferior than 10%.
An alternative to the pattern matrix for the factor analysis?
Kindly test the collected data for normality and distribution. If results don't fall in acceptable range then make an attempt to examine outliers ( remove if any). Then perform Exploratory factor analysis. Hope you may get the expected R-squired value.Following

A survey conducted by eircom shows that only 14% of parents post images, status updates or blog posts about their child(ren) on social media (vs. 90% in Australia, or 56% in the US, as per other studies).
Is there something about the Irish culture, or the technical infrastructure, that could explain such low levels?
If not, it is something about the sample, or about the question, right? Or could there be another reason that I am missing?
For reference, the question was: ‘Sharents’ are parents who blog, tweet and post pictures online about aspects of their children’s lives. Are you, or do you have the potential, to be a ‘Sharenter’ in the future?
eircom's report is available here: http://banda.ie/wp-content/uploads/eircom-Household-Sentiment-Survey-March-2014.pdf
Can I ask what was the scale of this question. You know that this is a double question. So response might be yes... or yes and I am 80% ... or yes and 50%.. or No at all... So it would help to see the question.
I would guess that cultural issues related to privacy perceptions are important here...

is there any supporting social networks and entrepreneurship
As a practicing entrepreneur, specializing in social and organizational network analysis, who is celebrating 20 years in business this year, I have observed the following network "rules" bring good results.
* strong ties are better than weak ties
* part of your network needs to be diverse, while another part needs to be homophilous
* structural holes are useful, but know when to close them
* connect on your similarities and benefit from your differences
* golden rule of networks is the same as the golden rule of real estate:

- 2Are there any written, detailed examples of social network contagion or social amplification in action in terms of stigma?
I am interested in connecting social network contagion and/or social amplification to a number of actual scenarios: negative and/or positive. I am particularly interested in replication of harmful rumor in proscribed, renewing populations such as neighborhoods and schools. In addition, I would like to see examples of crises caused by such social circumstances.
Good question that seldom asked! Given the growth in social networking especially among today's digital natives, I think it is important to address this issue of network contagion or social amplification. Our words and comments whether good or bad can remain in cyberspace infinitely so we need to find how what studies are revealing on the latter. Patricia has given you some very good sources alread, I'd just link to add a couple more:

I'm looking for work on how social networks can be exploited for the purpose of improving MOOC?
Social networks become a very useful tool to manage this type of course, encouraging student interaction, essential to the smooth running of the course. On the one hand to answer questions between them and the other to generate content. They are perfect to create learning communities that even last beyond the MOOC space.
Another advantage are the features of "viral" and openness, allowing to reach more students, including professionals in the field, and share all the achievements and course content, creating a major source of resources open result of the course.Following
- Violeta Beleva Guthrie added an answer:9Random walk betweenness centrality algorithm for a directed weighted graph?
I am interested in algorithms that do not use shortest paths to estimate node and edge centralities in directed weighted networks.
I have considered the algorithm by M.E.J. Newman, which was derived from a current flow analogy, therefore it seems to me it would not apply to a directed network: http://arxiv.org/pdf/cond-mat/0309045.pdf
I am also trying out the algorithm by Alahakoon et. al., from which I can get an approximation of the betweenness centralities for nodes, but the error terms and required run time have been derived for node and not edge betweenness: http://www.csee.usf.edu/~tripathi/kpath-centrality.pdf
Are there other (random-walk) algorithms can estimate both node and edge betweenness for my type of network?
Narasim, that's an interesting method, though I am not sure if it is in some way similar to the current flow analogy by Newman. Using diodes to simulate directed links seems to be new in the context of betweenness.
Asher and Henning, I knew about community finding methods based on high-betweenness edges, but had not thought about going in the opposite direction. Very curious about whether there is an algorithm out there!
Also, until recently there were not many and established methods for finding communities in directed networks, but that's another question altogether...
Many thanks! -VFollowing
- Mehdi Elmoukhliss added an answer:10What is the best voting method to use in crowdsourcing ?
Crowds evaluate contributions.
It seems that "likes" are mainly social grooming stuff, not really good predictor of content quality. At least it shows "popularity", but the link between popularity and quality is not evident.
Stars and more complex scales seems better (Riedl et al 2010). But I didn't find literature about new options (e.g. emotional icons).
Any idea ? I'll give you at least 4 stars ! ;-)
The question of whether collective intelligence is social or not is really important. Too many scientists consider it just 'aggregating' (mathematically) individual opinions. In the other hand, social influence is strong and not a must at all... I think it shall depend on the nature of the activity taken in charge (routine tasks vs evaluation vs creating vs deciding)... An interesting topic ! Thank you very much for those elements.

The Actor-Network Theory (Callon et al. 1986; Callon, 2001; Law and Hassard, 1999; Latour, 2005) also provide a useful tool for analyzing the nature and extent of actors’ involvement in creating and designing a variety of social events. It should be noted that the ANT early roots go back to ethnographic studies that focused on scientific creation within science laboratories (Callon, 1986; Latour, 1987; Law 1987; Law and Hassard, 1999; Latour, 2005).
ANT seeks to explicate how networks can strengthen “informal affinities” beyond the institutionalized ties in offices, factories, hamlets and parishes.Following
