Questions
MC1.1
– Provide a visual representation of the structure of the Protectors of
Kronos network, with supporting evidence.
b.
Who is part of the extended network?
c.
How has the group structure and organization changed over time?
d.
Where are the potential connections between the POK and GAStech?
Provide
novel visualizations appropriate for communicating key information to the busy
leaders of the investigation. Please limit your response to no more than eight
images and 500 words.
We
developed a data processor for MC1 with all the data (news, articles, resumes,
emails…) as input. Therefore it is easy to enquiry or analyze the information
as shown in the enquiry examples. Also D3 figures were used to visualize the
result.
a. Who are the leaders?
Before
2001, Henk Bodrogi was the
lead.
From
2001 to 2009, Elian Karel was the lead. The lead group included Mandor Vann, Silvia Marek, Isia
Vann, Lucio Jakab, and Lorenzo Di Stefano.
In
2009, Elian Karel died in prison. Silvia Marek was later the lead. The lead
group included Mandor Vann, Isia
Vann, Lucio Jakab, and Lorenzo Di Stefano.

for leadership enquiry
b. Who is part of the extended network?
Before
2001, Joclyn Reynolds (WFA project manager), Hank Fluss (GAStech COO) and Cesare Nespola (Government Minister of Health) were the extended
network.
After
2001, the network includes Silvia Marek and Lucio Jakab
network from Save Our Wildlands, and Professor Lorenzao Di Stefano from the University of Abila. It can be
seen that the extended network are absorbed into POK now.

enquiry
Figure 1.1.4 D3 collapse tree
for extended network enquiry
c. How has the group structure and organization changed over time?
Initially,
the organization was a small grass root group with seven people. Caminine Osvaldo helped the lead Henk
Bodrogi to connect with outside support, therefore
POK’s impact increased. Later, after the leadership transfer was done from Henk Bodrogi to Elian Karel in
2001, Elian started recruiting from local civils since the previous support
from Kronos government and GAStech disappeared. Local
organizations such as Save Our Wildlands joined POK.
Although Elian succeeded to maintain a peaceful struggle during his leading
time, after Elian’s death in 2009, POK’s protest and activities became more
radical.

enquiry

for POK period enquiry
d. Where are the potential connections between the POK and GAStech?
The
enquiry results shows two people as connections between GAStech
and POK. Hank Fluss was the supporter of POK in the
early stage (Grassroots Movement) as well as employee of GAStech.
Isia Vann is a current link between GAStech and POK since he is both a member in POK and an
employee in GAStech.
It
is interesting to see our algorithm reveals that the contaminated water is an
issue created by GAStech and concerned by POK.
Therefore the contaminated water issue connects POK GAStech
and POK, too.

MC1.2
– Describe the events of
January 20-21, 2014. What is the timeline of events? Please limit your response
to no more than ten images and 500 words.
The
co-occurrence count (relationship) among keywords and the TFIDF (unique
importance) of keyword are presented in time line as well as D3 bubble chart to
identify events. According to the time line text, we can have an overview to
key events. After that, for a given epoch, we check the bubble chart for
general information of events including people, location and actions. If the
event read from bubble chart is not clear enough, we can look at original news
text in a parallel window.
The
key events are listed in this section as MC1.2.x where x is the event number.

MC1.3
– Identify at least two
possible explanations why the GAStech employees may
be missing. What evidence do you have to support each of these explanations?
Please limit your response to no more than three additional images and 200
words.
One
possible reason is the revenge from Vann family in POK to GAStech
and Kronos government. The enquiry to Julianna showed she died of pollution
caused by GAStech in 1998. The local government did
not take strong measurements to prevent the harm or improve the situation.
Figure 1.3.1 Possible explanation - Julianna Vann’ death and family
revenge
Another
possible motivation is money. Due to the less support caused by the shrinking network,
POK may need financial support. Figure 1.3.2 showed there has been a $20
million ransom request from POK after the disappearance.
Figure 1.3.2 Possible explanation – Ransom request from POK on Jan. 21
12:00.
The
third motion behind the employee disappearance may be to beat the company as
well as to call people’s attention on the GAStech
pollution issue. As shown in figure 1.3.3, the IPO brought GAStech
huge profit to the cost of continuous pollution in Kronos. POK may use the
radical method to remind local people to protect the homeland.

and profits for executive members
