Victim-Centered Approach for Detection of Human Trafficking Victims
Experiment Initialization
To initialize the experiment runs , we used the following parameter ranges in Table 3 that reflect real-world representations ( where possible ) of the migration crisis on Germany ’ s border .
We ran 100 replications for each parameter combination specified in Table 3 , for a total of 1,100 runs , to complete the experiments .
Results
Figure 6 shows that the detection of trafficking victims first emerges when 48 % of the agent population starts with a cooperative strategy . Detection rates increase with the percentage of agents using our abstraction of cooperative strategies , stabilizing around 52 %. Figure 7 measures the number of seeded victims who were denied entry , despite being willing to cooperate . Because the willingness to cooperate is a function of interactions with other migrants , the results also provide an indication for how an overall culture of cooperation persists throughout the migrant population despite a country meeting its quota and closing its border . Results suggest that when initial cooperation intention of the population is > 52 %, nearly all seeded victims maintain a willingness to cooperate .
These results suggest initial treatment of trafficking victims has a significant influence on the success for victim detection , and that early propagation of a readiness to cooperate is important for sustaining victims ’ long-term willingness to cooperate . The more effectively the state can promote cooperation prior to interactions with state agents , the greater the contagion and persistence of cooperation in the population over time . These insights have implications for how states should proactively shape migrant perceptions and encourage self-identification . These findings can serve as a basis for further study of how state behavior influences individual strategies for interacting with authorities .
In addition to a computational exploration for the underlying mechanics of the victim-centered approach , model outcomes suggest for our abstraction of the problem , a victim-centered approach facilitates the identification of victims . Both the economic and humanitarian immigration policies performed better when paired with the victim-centered approach .
