Communicative Space

There is a tendency, particularly among Western pundits and technologists, to examine the Internet in almost universally positive terms; this is most evident in any discussion of the medium’s capacity for democratization. While the Internet has produced many great things for society in terms of cultural and economic production, some consideration must be given to the implications that such a revolutionary medium holds for the public sphere. By creating a communicative space that essentially grants everyone his or her own microphone, the Internet is fragmenting public discourse due to the proliferation of opinions and messages and the removal of traditional gatekeepers of information. More significantly, because of the structural qualities of the Internet, users no longer have to expose themselves to opinions and viewpoints that fall outside their own preconceived notions. This limits the robustness of the public sphere by limiting the healthy debate that can only occur when exposed to multiple viewpoints. Ultimately, the Internet is not going anywhere, so it is important to equip the public with the tools and knowledge to be able to navigate the digital space.

The article considers some aspects of the development of the digital economy – the part of economic activity that relies on the use of information technologies. The digital economy, its volume and complexity of structure are rapidly growing. Its direct impact on economic processes in any country is obvious. It is emphasized that in the era of the digital economy, the main resource is accurate, reliable, truthful and timely information.

The Right

Introduction. The era of digitalization sets for researchers the task of systematizing the essential features of digital space, identifying the essence of the “right to the Internet” and the legitimacy of limiting the digital rights of citizens. Theoretical Basis. Methods. The authors studied the peculiarities of the digital environment as a specific integral area of legal regulation, the doctrine and legislation of several countries on the topic which determines the basis for the regulation of digital space in Russia. The formal legal method, synthesis, analysis, induction and deduction were used as research methods. Results. The wording of the basic concepts in the area under study is proposed: digital space, digital region, digital platform, etc. The measures to eliminate “digital wells” are indicated. The main properties of the information space and its derivatives are considered. The effects of any contradictions in the legislation of the country are shown. Discussion and Conclusion. As the study showed, the latest innovations in the legislation contravene the principle of the balance of interests, fail to meet the requirements of observing the rights of a person and citizen, and contradict the Constitution and international treaties of Russia. When comparing these measures with their foreign counterparts, a search was made for their potential shortcomings and proposals were presented on possible directions for their correction, taking into account the particular characteristics of digital space.

Neighborhood Interaction

Chapter 2 explains that street life moves online through girls and boys and their relations to one another. This chapter shows how girls and boys use social media to manage their encounters and the value this holds for girls especially, but boys as well. The author uses several cases, including JayVon and Denelle, to illustrate the ways in which interaction moves between the physical street and the digital street. The chapter then examines the feedback effects between gender and the street code. The author finds that whereas turf lines bind boys to their home streets, girls become brokers for themselves and boys dependent upon their loyalty. This chapter argues that focus only on the physical side of neighborhood interaction has led to the false assumption that boys control the street. By considering physical and digital space together, the mobility and centrality of girls in neighborhood networks become sharply clear.

Common Target

Information systems of critical infrastructure provide services on which the core functions of a state and its economy depend as well as welfare of society. Such systems are becoming an increasingly common target for crimes and attacks in cyberspace, as their vulnerabilities can be exploited for malicious activities seeking financial or political gain. One of the main reasons that threatens the security of these systems is the weak control of remote access, otherwise defined as management of a system’s user identity. Management of user identity depends on user authentication, authorization and the assignment of certain rights in the digital space. This paper provides the proposed two-factor (2FA) digital authentication method for remote access to an information system of a critical infrastructure. Results of testing the method’s usability and resilience to cyber threats have shown that the system, in which the method was implemented, is protected from dangerous HTTP requests and publicly available system’s endpoints are protected from threatening inputs that could cause malicious activities on the critical infrastructure. Additionally, the implementation of the authentication API application ensures the rapidity of the method for less than 500 ms for 100 users working in parallel with the system at the same time.

AbstractPhase singularities appear ubiquitously in wavefields, regardless of the wave equation. Such topological defects can lead to wavefront dislocations, as observed in a humongous number of classical wave experiments. Phase singularities of wave functions are also at the heart of the topological classification of the gapped phases of matter. Despite identical singular features, topological insulators and topological defects in waves remain two distinct fields. Realising 1D microwave insulators, we experimentally observe a wavefront dislocation – a 2D phase singularity – in the local density of states when the systems undergo a topological phase transition. We show theoretically that the change in the number of interference fringes at the transition reveals the topological index that characterises the band topology in the insulator.
