Latin American Studies Around the World: Southampton Hosted the 2018 SLAS Conference

Last week the University of Southampton hosted around 200 experts on Latin American Studies from all over the world who gathered at the 2018 Society of Latin American Studies’ Annual Conference to reflect on the history and current state of Latin American Studies in the UK and around the world.


A team of ten students from Social Sciences and Humanities were part of the organising team, based at PAIR, and efficiently run this two-day event at the Winchester campus. For most of these students, it was their first experience on a professional academic event of this size and prestige. They enthusiastically combined work experience with attendance to panels and networking with the experts in their favourite topics.

Reflections on the International Conference for E-Democracy and Open Government 2014

By Mark Frank, PhD Student in Politics & International Relations and WebScience.

On the 21st to 23rd of May I attended the International Conference for E-Democracy and Open Government 2014  (CEDEM 2014) in Krems in Austria.  I was there because they accepted a short paper (what they call a reflection) written by myself and Phil Waddell.  As far as I know, no one from Southampton, much less PAIR, has ever attended CEDEM although it has been going every year since 2008. So I thought it would be worth saying a bit about it.

Most of all – I highly recommend it.  The conference title is a pretty good description. So if you are interested in the interaction between the Internet and Democracy then this may be a good conference for you. It is organised by the Danube University of Krems – which is an interesting university. It is aimed at continuing education for working professionals – postgraduate only and specialising in short or masters’ courses with a lot of part-time and distance learning.  The main conference is always in Krems, although they also run an Asian version which moves from place to place.

It was a small conference (120 people and three tracks) and but very friendly and well-organised and of a high standard. As my interest is Open Data I concentrated on that track and found the majority of the papers to be valuable. With hindsight I think that ideally I would have spent more time in other sessions, as this track, while fascinating, was more technology oriented than I expected. For example a paper on ways of automatically assessing data quality and another comparing different platforms for presenting open data. The e-Democracy and e-Participation track was more concerned with the political implications of technology (this divide may reflect two different views of Open Data in the world at large). However, the keynote speakers and the brief presentations of the reflections presented a wide variety of perspectives on e-government from round the world. Alexander Gerber on Scientific Citizenship was a particular highlight, although I disagreed quite strongly with his thesis of upstream scientific engagement which seemed to imply that the direction of scientific research should be decided democratically. The small and specialist format seemed to permit keynote speakers who were less bland and more approachable than is often the case at large conferences.

The biggest benefit of any conference is always talking to the other attendees and here CEDEM 2014 really scored. The theme of the conference was well defined and not too broad so I found that I had common interests with almost everyone there. And everything about the three days made it easy to meet and talk. It is small and informal and there were numerous social events. The UK is a leader in Open Data and it is easy to neglect what is going on in the rest of the world. This was an excellent reminder that this is a truly global movement albeit with very different perspective in different countries.

Reviewing the 2014 Political Studies Conference with Twitter Data

By Justin Murphy, Lecturer, University of Southampton  @jmrphy

What were the most talked-about issues during the 2014 Political Studies Conference in Manchester last week? How are those issues connected? How many attendees used Twitter? How was that communication network structured? How did sentiment change over time throughout the conference?

To get some leverage on questions such as these, below I analyze all the tweets containing the hashtag #PSA14 between Monday April 14 (roughly 9 a.m.) until Wednesday April 16th (roughly 8 p.m.). The Twitter API only provides 1500 tweets per call but, conveniently, that allows us to analyze every tweet during this period. As with all social media data, this data is almost certainly not representative of the whole population of attendees. Needless to say, these analyses do not describe the conference as such, but only that portion of the conference which took place on Twitter!

The dynamics of conference tweeting

No big surprises here. Conference tweeting typically peeked in the middle of each day, and the middle day of the conference saw the most Twitter activity. Each bar represents a 30-minute interval.


Who tweeted the most?


Who received the most retweets?


Who received the most retweets, as a ratio of total tweets?

Retweets are an indicator of influence, but people who tweet frequently will be retweeted more than infrequent tweeters, so a better measure of influence is retweeted tweets as a ratio of total tweets.


What was the network structure of retweets?

Who retweeted who, visualized as a network.


Centrality and Brokerage

Number of retweets is a good first look at influence, but not all retweets are equal in network terms. A tweet which is retweeted from someone who is also often retweeted is more influential than receiving retweet from someone who is rarely retweeted. This is what is captured by the network concept of “eigenvector centrality.” On the other hand, there might be nodes in the network which are not necessarily retweeted very frequently or by influential nodes, but are important nodes because they connect many other nodes who otherwise would not be connected. “Betweenness centrality” captures the degree to which a node sits on the shortest path between all other actors. Typically, eignevector centrality and between centrality will be positively correlated, and this is a straightforward indication of the power of that node in the network. But nodes off the diagonal represent other kinds of power. Nodes with high eigenvector centrality but low betweenness centrality are relatively powerful nodes but relatively outside the community. Nodes with high betweenness centrality but low eigenvector centrality are “brokers” who are not high-visibility but are powerful because a relatively high number of nodes go through that node to stay connected.

Thus, this graph helps us identify interesting nodes in the conference network, which we would not notice by just looking at who tweeted the most and who was retweeted the most. The businessman and journalist @MarkFox__ did not tweet much on #PSA14, and he’s a relative outsider to the network, but when he tweeted he was disproportionately retweeted by the most influential nodes within the network. @chrisgold was not retweeted very frequently by very influential nodes, but a relatively high number of nodes are connected to the rest of the network through him.


Note: That some of the usernames here have an “@” in front but some of them don’t suggests that there might have been a small error in some of the text-processing of usernames. I would fix this, if it were anything more than a blog post! It doesn’t seem to be much of a problem, as everything else is very consistent with what we would expect.

How positive/negative was the conference tweeting?

I used the Hu and Lui sentiment lexicons to do a basic “sentiment analysis” of the conference tweets. A sentiment lexicon is basically one large list of negative words and one large list of postive words. It sounds naive but it works, as evidenced by how much this is used in marketing. The sentiment of a tweet is simply the number of postive words minus the number of negative words.


How did the overall sentiment change over the course of the day, on average?


How did the overall sentiment change throughout the conference, by the hour?


What were the most frequent terms tweeted, and how were they associated?

Below are the 50 terms which appear most frequently throughout the 1500 tweets (I use stems of words rather than whole words to avoid redundancy, as is conventional in text-mining). The first several are terms related to the conference, but then several substantive political issues emerge. Some notable themes include: youth politics, UKIP, engagement and participation, and media.

How were these main themes connected?

In other words, how did the most-tweeted terms cluster in the entire network of terms discussed? To understand this better, we can visualize the entire vocabulary of the 1500 tweets as a network. Every word which appears in a tweet with another word, represents a non-directional connection. Below is a graph of this network with the most central nodes highlighted and labeled.
