We model the contiguous states (48 states and the District of Columbia) of the United States (US) as an undirected network graph with each state represented as a node and there is an edge between two nodes if the corresponding two states share a common border. We determine a ranking of the states in the US with respect to the four commonly studied centrality metrics: degree, eigenvector, betweenness and closeness. We observe the states of Missouri and Maine to be respectively the most central state and the least central state with respect to all the four centrality metrics. The degree distribution is bi-modal Poisson. The eigenvector and closeness centralities also exhibit Poisson distribution, while the betweenness centrality exhibits power-law distribution. We observe a higher correlation in the ranking of vertices based on the degree centrality and betweenness centrality.

We considered the problem of formation of personal brand through content of social networks. Based on modern works on personal branding and classification proposed by image-making specialists, we considered strategies and technologies for creating a personal brand by two creative personalities in a comparative aspect: P. Drangoy and A. Vorobyov. We understood a personal brand as a complex of images and associations that is actualized in the minds of people when mentioning the name of a certain person. We modeled P. Drangi and A. Vorobyov's personal brands by determining the competencies, standards and style that they broadcast in the Internet space; key image characteristics of both artists are analyzed, we considered image in four dimensions: visual, verbal, context and event. We used the comparative analysis method and the content analysis method as the basic ones. The material for the study was content posted by musicians on personal official pages on social networks. The appeal to this content made it possible to determine the general in building the image of the star of the modern scene, taking into account the individual characteristics of each musician. In conclusion, we made the conclusion about the ability of an account on a social network to influence the artist's image, his concert activity and career trajectory.
