It is a small data set of dynamics of networks and behavior
for which SIENA can provide estimates relatively quickly.
The data were collected by Andrea Knecht. The
full data set (see Knecht, 2008) contains a large number
of classrooms - this is only one.
Background
This data is about a friendship network in a Dutch school class. The data were collected between September 2003 and June 2004 by Andrea Knecht, supervised by Chris Baerveldt, at the Department of Sociology of the University of Utrecht (NL). The entire study is reported in Knecht (2008). The project was funded by the Netherlands Organisation for Scientific Research NWO, grant 401-01-554.
The 26 students were followed over their first year at secondary school during which friendship networks as well as other data were assessed at four time points at intervals of three months. There were 17 girls and 9 boys in the class, aged 11-13 at the beginning of the school year. Network data were assessed by asking students to indicate up to twelve classmates which they considered good friends.
Delinquency is defined as a rounded average over four types of minor delinquency (stealing, vandalism, graffiti, and fighting), measured in each of the four waves of data collection. The five-point scale ranged from `never' to `more than 10 times', and the distribution is highly skewed. In a range of 1-5, the mode was 1 at all four waves, the average rose over time from 1.4 to 2.0, and the value 5 was never observed.
Coding
The friendship networks are in adjacency format in the
files klas12b-net-1.dat
to klas12b-net-4.dat
.
They are coded as follows.
File klas12b-delinquency.dat
contains
a variable about delinquency for waves 1-2-3-4, coded as follows.
File klas12b-alcohol.dat
contains
a variable about alcohol use,
but it refers only to waves 2-3-4.
The file klas12b-demographics.dat
contains
the following four variables.
The file klas12b-advice.dat
contains
the variable "school advice", the assessment given at the
end of primary school about the school capacities
of the pupil
File klas12b-primary.dat
contains
a variable indicating having gone
to the same primary school.
File klas12b-present.dat
contains
a variable indicating changing composition in the format
equired by RSiena.
RSiena script
klas12b.r
Network dynamics, treating the pupil who left using the changing composition file (leaving immediately after wave 2).
RSiena setup files
(obsolete; can still be used in RSienaTest,
function sienaDataCreateFromSession)
klas12b_net.csv
Network dynamics, treating the pupil who left using the changing composition file (leaving immediately after wave 2).
klas12b_neta.csv
Network dynamics, treating the pupil who left as missing data.
klas12b_netbeh.csv
Dynamics of networks and behavior, treating the pupil who left
by structural zeros.
klas12b_netbeha.csv
Dynamics of networks and behavior, treating the pupil who left
as missing data.
