+## Networks & Palladio, 23/10/2024
+
+In this lesson on social networks, the concept is introduced using the example of a wedding party to illustrate several fundamental notions. Terms like “reciprocity” are highlighted, meaning that a relationship in a network must be mutual for it to work both ways. Guests each have an “ego” network, their own group of immediate relations. Networks are also delimited by boundaries. For example, wedding guests are divided according to attributes such as age, interests or relationship status. The way these people interact within their groups, creates specific dynamics. At the old people’s table, conversations often come from a single person, forming a particular network pattern that contrasts with that of singles, where there is a greater density of connections. There's also the term “broker”, which refers to a person who circulates from one network to another. In other words, network structures are therefore dynamic and can change over time, with information and relationships evolving in line with interactions. There's also the difference between “unipartite” and “bipartite”. Social networks are also made up of affiliations and interactions, and the concept of social network is founded upon four essential dimensions: the self-perception of historical actors, its function as a metaphor for groups of related actors, its role as a constructed object of scholarly research and its use as a theory/method driven approach to research. To conclude this theoretical part, we had to create a network visualization ourselves, using the “Palladio” tool. A particularly useful tool for exploring relationships between different elements, and therefor ideal for analyses in research projects.

 ## Maps, 16/10/2024
 
 This 5th course taught us more about maps, and particularly the “StoryMaps” tool. After trying our best to represent the Belval campus on a map, we learned more about Geographic Information Systems (GIS), which are analysis and visualization tools that go beyond the simple creation of maps. 2 leading software packages exist: ArcGIS and QGIS. These programs enable to superimpose different layers of information. This course reminded me that maps are an essential tool for researchers and historians because of their considerable informative impact. In addition to star maps or location maps, there are also topographic maps, also known as reference maps and thematic maps.
