Group Colocation Behavior in Technological Social Networks.
We analyze two large datasets from technological networks with location and social data: user location records from an
online location-based social networking service, and anonymized telecommunications data from a European cellphone
operator, in order to investigate the differences between individual and group behavior with respect to physical location.
We discover agreements between the two datasets: firstly, that individuals are more likely to meet with one friend at a place
they have not visited before, but tend to meet at familiar locations when with a larger group. We also find that groups of
individuals are more likely to meet at places that their other friends have visited, and that the type of a place strongly affects
the propensity for groups to meet there. These differences between group and solo mobility has potential technological
applications, for example, in venue recommendation in location-based social networks.
ABUSE OF COMPUTER NETWORKS IN CYBER SPACE: THE ROLE OF FAMILY IN THE MODERN INFORMATION AGE.
The Internet introduced a global change in the methods and speed of communication,
exerting significant influence on the quality of life of a "common individual".
This influence can be observed in all spheres of social life in our environment.
Nevertheless, positive and constructive achievements of modern information technology
also caused a series of problems related to the emergence and expansion of diverse
forms of computer crime. This is a relatively new form of criminal behavior that
exhibits major phenomenological diversity and that cannot be defined by a single
definition. Even though certain definitions have been adopted, the phenomenon of
cyber crime has appeared as a much broader concept. There are numerous documents
that classify various forms of cyber crime. The fact is that uncontrolled and aimless
use of the Internet implies numerous dangers. Internet abuse is often associated with
pornography, which implies that various websites with illegal content also influence
the long-term "poisoning" of children. Despite the primary and essential role of the
parents, the support of all social segments is necessary in order to raise collective
awareness through media and educational campaigns dedicated to youth and children,
all for the purpose of providing information about potential Internet abuses and methods
of safe usage.
