In the second part of the course we look at how we can start thinking about a social network from a social and technical point of view. Firstly we introduce network theory, and then use this theory to examine a small office network, to see if it can tell us who is the most powerful person in that network.
Section 1: What are Networks?
In this video Dr. David Millard discusses the networks around us, and gives a brief introduction to network theory.
Section 2: Task - Office Network
Watch the first video, and then use the pdf files to have a go at the task, once you have finished watch the reflection video
This short video introduces a simple task which is for you to analyse a small office network. Watch this video and follow the instructions. You will need the four pdf files also included in this session to complete the task. Once you have finished you can look at the next video (which is called Reflection).
Section 3: Discussion
These are questions you might like to discuss with your classmates once you have all attempted the task:
- Of the three we introduced which is the best measure of power in this network?
- Would you get a different answer if you analysed the content of the messages, rather than the structure of the network?
- Do you think these analyses are a good way of measuring power and influence in a social group? What might they miss?
