Abstract:

Purpose The purpose of this paper is to understand the role of corporate social responsibility (CSR) communications in business by merging previously unconnected lines of thought in communications and law. Using Walmart as an example, the study shows that CSR communication can legitimize a corporation’s autonomous legal system of regulation and governance over its business practices. Design/methodology/approach A qualitative case study of all online corporate communications webpages from Walmart was examined. Discourse and qualitative analyses were used to show how language and online communications practices created actional legitimacy for Walmart’s CSR practices. Findings Using the UN’s Guiding Principles for Business as a framework for analysis, the study demonstrated how CSR communications helps Walmart to establish its own system of CSR norms, structures and remediation processes for its business outside of the state. These communications also sought to legitimize these actions among stakeholders. Research limitations/implications This case study looks at one corporation (Walmart) to illustrate a new connection between CSR communication and legitimacy. Future research in communications can extend this line of inquiry by examining how communications can reinforce autonomous legal systems and public perceptions. Originality/value Backer’s (2007) autonomous legal system and the concept of actional legitimacy in communications have not yet been studied systematically. This case study demonstrates how CSR communications can legitimize a multinational corporation’s business practices, which, in turn, raises ethical considerations for the ways this communication serves the greater society.

Abstract:

Rapid emergence of antimicrobial resistance (AMR) has become a critical challenge worldwide. It is of great importance to understand how AMR is modulated genetically in order to explore new antimicrobial strategies. Recent studies have unveiled that microbial communication systems, which are known to play key roles in regulation of bacterial virulence, are also associated with the formation and regulation of AMR. These microbial cell-to-cell chemical communication systems, including quorum sensing (QS) and pathogen–host communication mechanisms, rely on detection and response of various chemical signal molecules, which are generated either by the microbe itself or host cells, to activate the expression of virulence and AMR genes. This article summarizes the generic signaling mechanisms of representative QS and pathogen–host communications systems, reviews the current knowledge regarding the roles of these chemical communication systems in regulation of AMR, and describes the strategies developed over the years for blocking bacterial chemical communication systems in disease control. The research progress in this field suggests that the bacterial cell-cell communication systems are a promising target not only for disease control but also for curbing the problem of microbial drug resistance.

Abstract:

The current paper studies guaranteed cost time-varying formation tracking design and analysis problems of high-order swarm systems subject to intermittent communications. Different from the existing work of the time-varying formation control, the time-varying formation tracking can be achieved while certain performance can be guaranteed, and the impacts of the intermittent communications and switching topologies are considered. First, a new intermittent time-varying formation tracking control protocol with a global performance index is proposed, where not only the formation regulation performances but also the control energy expenditures are involved. The codesign of the gain matrix with the performance index is achieved to compromise the formation regulation performances against control energy expenditures, and the guaranteed cost is determined to restrain the upper bound of the performance index. Then, guaranteed cost time-varying formation tracking design and analysis criteria are given, where the matrix variable of the linear matrix inequality conditions is used to design the gain matrix and to determine the guaranteed cost. Finally, a simulation example is provided to illustrate the effectiveness of the theoretical results.

Abstract:

This article presents a novel approach to the analysis of wireless sensor networks (WSN) security, based on the regulations intended for wireless communication devices. Starting from the analysis and classification of attacks, countermeasures, and available protocols, we present the current state on secure communication stacks for embedded systems. The regulation analysis is based on civil EN 50150 and MIL STD-188-220, both applicable to WSN communications. Afterwards, starting from a list of known WSN attacks, we use a correspondence table to match WSN attacks with countermeasures required by regulations. This approach allows us to produce a precise security evaluation and classification methodology for WSN protocols. The results show that current protocols do not present a complete coverage of security issues. While this conclusion is already known for many WSN protocols, to the best of our knowledge this is the first time a complete methodology is proposed to base this assertion. Moreover, by using the proposed methodology, we are able to precisely identify the exposed threats for each WSN protocol under analysis.

Abstract:

Systems regarding the legal remedy of communication interception can be found in several regulations. However, those systems are not supported by horizontal harmonization since each regulation governs the mechanism differently, so there is a disparity among interception regulation. This paper analyzes the harmonization of wiretapping regulations in Indonesia from a law enforcement perspective with an inventory of regulations governing the current mechanism of interception. The results concluded that first, the disparity in intercepting authority of communication interception practice regulated by several institutions in the same form of crime eradication authority must be reformulated to restore overlapping regulations. Secondly, the interception regulation as a coercive force that derogates the right to privacy must contain detailed provisions in terms of a permit request and the wiretapping authority. The permit application must contain the purpose of the request for wiretapping permission descriptively. Moreover, these provisions must explicitly regulate legal subjects that are authorized to conduct wiretapping practice in the form of clear mechanisms and coordination with the direct superiors and court supervision regulating the interception procedure as well as the cooperation between law enforcement officials and telecommunications service providers. Third, prospectively interception regulations can be assessed from the political will of the legislators. The decision of the Constitutional Court No. 5/PUU-VIII/2010 mandates the need for horizontal harmonization of interception regulations in the form of the Interception Bill, which is also included in the 2019 National Legislation Program.

Abstract:

The blockchain technology achieves security by sacrificing prohibitive storage and computation resources. However, in mobile systems, the mobile devices usually offer weak computation and storage resources. It prohibits the wide application of the blockchain technology. Edge computing appears with strong resources and inherent decentralization, which can provide a natural solution to overcoming the resource-insufficiency problem. However, applying edge computing directly can only relieve some storage and computation pressure. There are some other open problems, such as improving confirmation latency, throughput, and regulation. To this end, we propose an edge-computing-based lightweight blockchain framework (ECLB) for mobile systems. This paper introduces a novel set of ledger structures and designs a transaction consensus protocol to achieve superior performance. Moreover, considering the permissioned blockchain setting, we specifically utilize some cryptographic methods to design a pluggable transaction regulation module. Finally, our security analysis and performance evaluation show that ECLB can retain the security of Bitcoin-like blockchain and better performance of ledger storage cost in mobile devices, block mining computation cost, throughput, transaction confirmation latency, and transaction regulation cost.

Abstract:

Information and communications technologies (ICT) are usually given attention primarily from the standpoint of the technical aspects. However the legal aspects of this specific area cannot be forgotten, as they significantly influence the efficacy and usefulness to entrepreneurial subjects i.e. the conditions for making business transactions. ICT are one of the factors that markedly influence agricultural primary production and the food industry as well as all other branches of the economy. Therefore it is necessary to analyse the effect Community legal regulations for electronic transactions have on resource utility. The aim of the paper is to analyse the state of the legal regulation of information and communication technologies in the food industry in the CR in comparison with Community law. Currently a basic overall source of law for the ICT area does not exist in the CR in an integral form. This branch of law is regulated complementarily in a whole number of varying legal regulations. With regards to the specifics of the media used in the ICT framework it is essential to resolve certain issues differently from the general regulations.The paper has resulted from the institutional research intention MSM 6046070906 “The Economics of Resources from Czech Agriculture and their Efficient Use in the Framework of Multifunctional Agri-food Systems“.

Abstract:

The myocardium is a highly structured tissue consisting of different cell types including cardiomyocytes, endothelial cells, fibroblasts, smooth muscle cells, inflammatory cells, and stem cells. Microvascular endothelial cells are the most abundant cell type in the myocardium and play crucial roles during cardiac development, in normal adult myocardium, and during myocardial diseases such as heart failure. In the last decade, epigenetic changes have been described regulating cellular function in almost every cell type in the organism. Here, we review recent evidence on different epigenetic changes that regulate intercellular communication in normal myocardium and during myocardial diseases, including cardiac remodeling. Epigenetic changes influence many intercellular communication signaling systems, including the nitric oxide, angiotensin, and endothelin signaling systems. In this review, we go beyond discussing classic endothelial function (for instance nitric oxide secretion) and will discuss epigenetic regulation of intercellular communication.

Abstract:

We present a study of interfacial pattern formation during growth of bacterial colonies. Growth of bacterial colony bears similarities to but presents an inherent additional level of complexity compared to non-living systems. In the former case, the building blocks themselves are living systems each with its own autonomous self-interest and internal degrees of freedom. At the same time, efficient adaptation of the colony to adverse growth conditions requires self-organization on all levels — which can be achieved only via cooperative behavior of the bacteria. To do so, the bacteria have developed sophisticated communication channels on all levels. Here we present a non-local communicating walkers model to study the effect of local bacterium-bacterium interaction and communication via chemotaxis signaling. We demonstrate how communication enables the colony to develop complex patterns in response to adverse growth conditions. Efficient response of the colony requires self-organization on all levels, which can be achieved only via cooperative behavior of the bacteria. It can be viewed as the action of an interplay between the micro-level (the individual bacterium) and the macro-level (the colony) in the determination of the emerging pattern. Some qualitative features of the complex morphologies can be accounted for by invoking ideas from pattern formation in non-living systems together with a simplified model of chemotactic "feedback."

Abstract:

Abstract The immune and nervous systems share many features, including receptor and ligand expression, enabling efficient communication between the two. Accumulating evidence suggests that the communication is bidirectional, with the neural system regulating immune cell functions and vice versa. Steroid hormones from the hypothalamus–pituitary–adrenal gland axis are examples of systemic regulators for this communication. Neural reflexes describe regional regulation mechanisms that are a historically new concept that helps to explain how the neural and body systems including immune system communicate. Several recently identified neural reflexes, including the inflammatory reflex and gateway reflex, significantly impact the activation status of the immune system and are associated with inflammatory diseases and disorders. Either pro-inflammatory or anti-inflammatory effects can be elicited by these neural reflexes. On the other hand, the activities of immune cells during inflammation, for example the secretion of inflammatory mediators, can affect the functions of neuronal systems via neural reflexes and modulate biological outputs via specific neural pathways. In this review article, we discuss recent advances in the understanding of bidirectional neuro-immune interactions, with a particular focus on neural reflexes.

Abstract:

Unsolicited correspondence — so called ‘spam’ — is inextricably linked to electronic communications. It is widely considered to be the scourge of the information age and a crucial problem in respect of internet security. The phenomenon is closely associated with the development of electronic communications services. Taking into account the intense legal regulation, and not only that in EU countries, it is important to put the question — what is the reasons that current regulations seems to be insufficient. Is their ineffectiveness a result of objective factors such as the evolution of the phenomenon and insufficient flexibility of legal norms? Or maybe, legal protection models are based on a prior false assumption that it is possible to cope with a global problem and to protect against spam through national or regional regulations? The aim of this article is to try to answer these questions and, on the basis of comparative studies, try to create minimum standards for national legislation in the field of protection against spam. In my opinion the effectiveness of anti-spam regulation depends on the resources of law enforcement and the scope of the competences held by public authorities. Opportunities for international cooperation and cooperation with internet service providers and organisations in the private sector play an important role in the process of applying the law. The comparative studies on national legislations, EU directives and regulations of the OECD model indicate that the effectiveness of anti-spam protection depends on definitional consistency in describing the phenomenon in the widest possible range of national legal systems and of close international cooperation between competent national authorities.

Abstract:

This article discusses the provisions of the current legislation of the Republic of Kazakhstan and the Republic of Uzbekistan, regulating the field of electronic document management. The article considered the regulatory legal acts of the Republic of Kazakhstan and the Republic of Uzbekistan, regulating the issues of drawing up an electronic document and implementing electronic document management, such as: the Law of the Republic of Kazakhstan "On electronic documents and electronic digital signature" dated January 7, 2003; The Law of the Republic of Uzbekistan "On Electronic Document Management"; Law of the Republic of Kazakhstan "On Informatization" dated November 24, 2015 No. 418; Law of the Republic of Uzbekistan "On informatization" dated December 11, 2003 No. 560; Law of the Republic of Kazakhstan dated July 26, 2016 No. 11"On payments and payment systems"; Law of the Republic of Uzbekistan dated November 1, 2019 No. 578 "On payments and payment systems". When considering the issue of drawing up an electronic document in electronic document management systems, it is clear that the issue of certifying an electronic document with a seal in the necessary cases has not been settled. For a document to be considered signed and certified with a seal, it is necessary that such a signature and seal be included in the electronic document. Today there is a formal obstacle to the electronic document flow of documents, the creation of which is carried out on special paper forms with coats of arms or emblems. This requirement applies to certain types of statutory, financial documents, notarized documents, etc. In connection with the widespread use of information communications, the problem of information security, the existing systems for storing, transferring and processing information, becomes very important for society. Currently, the prevailing epidemiological situation in the country and in the world has significantly accelerated the exchange of data in electronic form in all spheres of society. Almost all activities of the society have switched to the electronic format of information exchange, including entrepreneurship. We hope that in the Republic of Kazakhstan and in the Republic of Uzbekistan, the development of the digital economy model will have a productive effect on the development of entrepreneurship and help overcome the problems existing in business.

Abstract:

The design of compact dual band grid array antenna (GAA) designed on FR-4 substrate for future Fifth Generation (5G) Mobile Communications at 10 GHz is reported. The proposed antenna uses coaxial technique of feeding and has a dimension of 48 mm × 55 mm × 1.6 mm. Simulation results using CST microwave studio illustrates that the antenna has a band from 10.03 GHz to 10.68 GHz and another band from 10.7 GHz to 12.23 GHz. This excludes the 10.68 – 10.7 GHz band in which emissions were forbidden by the Radio Regulations in the sense that it has been allocated for the Radio Astronomy, Space Research and Earth Exploration Satellite (passive). The antenna has a maximum gain of 8.03 dBi at 10 GHz, thus a good candidate for the future 5G mobile communications.

Abstract:

Understanding organisms from a systems perspective is essential for predicting cellular behaviour as well as designing gene-metabolic circuits for novel functions. The structure, dynamics and interactions of cellular networks are all vital components of systems biology. To facilitate investigation of these aspects, we have developed an integrative technique called network component analysis, which utilizes mRNA expression and transcriptional network connectivity to determine network component dynamics, functions and interactions. This approach has been applied to elucidate transcription factor dynamics in Saccharomyces cerevisiae cell-cycle regulation, detect cross-talks in Escherichia coli two-component signalling pathways, and characterize E. coli carbon source transition. An ultimate test of system-wide understanding is the ability to design and construct novel gene-metabolic circuits. To this end, artificial feedback regulation, cell–cell communication and oscillatory circuits have been constructed, which demonstrate the design principles of gene-metabolic regulation in the cell.

Abstract:

The random data loss that occurs during the communication process of multi-agent systems will lead to the dynamic switching of network topology. The time-varying communication delay will cause the agents to update their control inputs irregularly and asynchronously. In this paper, we deal with the cooperative output regulation problem of multi-agent systems with both random data loss and time-varying communication delay. By applying a queuing mechanism, the multi-agent systems with time-varying communication delay can be modeled as the multi-agent systems with constant communication delay and stochastic packet dropout. Based on the queuing mechanism, we designed the distributed state observers of the leader and the followers. Then, a new distributed measurement output feedback control algorithm is proposed. Under some standard assumptions, the proposed algorithm can solve the cooperative output regulation problem of multi-agent systems with both stochastic packet dropout and time-varying communication delay for unstable or stable exosystem. Then, the corresponding conditions for solving the cooperative output regulation problem are given, respectively. The simulation results show that the measurement output feedback control algorithm based on queue mechanism can effectively solve the cooperative output regulation problem of multi agent systems with time-varying delay under dynamic network topology.

Abstract:

Purpose – The aim of this paper is to test the moderating role of emotion regulation in the transformation of both task and process conflict into relationship conflict. Design/methodology/approach – A field study of multi-teams systems, in which (94) respondents are engaged in interpersonal and inter-team interactions, was conducted to test the effects of the interaction of emotion regulation and task and process conflict on the emergence of relationship conflict in 23 multi-team client/supplier systems. Findings – The findings show that when collective emotion regulation strategies are effective, process conflict is less likely to transform into relationship conflict. An emerging finding of this study shows that process conflict mediates the interaction between task conflict and emotion regulation on relationship conflict in multi-team systems. Research limitations/implications – This study uses a relatively small number of projects and participants: further studies with larger samples are recommended; in addition, longitudinal studies would allow for further testing the effect of team longevity in the emergence of effective emotion regulation strategies.ct transforming into relationship conflicts. Practical implications – The findings imply that managers of multi-team systems should actively try to stimulate their teams to develop effective emotion regulation strategies as effective emotion regulation mechanisms minimize the risk of process conflict transforming into relationship conflicts. Originality/value – The paper looks at a real-world (as opposed to lab-situation) environment; it addresses a contingency model of intra-group conflict and tests the transformation of task and process conflicts into relationship conflict taking into account the moderating effect of emotion regulation.

Abstract:

The caste in which workers and occupational health practitioners find themselves is plagued by intertwined but separable conflicts. A Cartesian model of causation, useful in the demonologies of regulation and toxic torts, is not heuristic in the revisions of health care, worker's compensation, and disability systems, nor in the prevention of violence in the workplace. Outside the caste, science progresses beyond mind-body bifurcations, the adverse effects of which are magnified within the caste. An argument is made for an ecological concept of causation, drawn from Darwin's community approach to the web of causal factors in both cultural and biological evolution, subsequently stimulated and developed by G. H. Mead and by biologically oriented and sociologically oriented human ecologists for application in the workplace. The ecological model is found in occupational biomedicine as practiced by leaders as diverse as Tichauer and Selikoff. The model integrates environmental, lifestyle, and genetic vectors in a community system bonded by communication and embracing a view of work unbifurcated from other activities.

Abstract:

Research on Intelligent Cooperative Systems (ICS) based on wireless vehicular communication to improve automotive safety and traffic efficiency is being promoted through initiatives such as the Vehicle Safety Communications Consortium (VSCC) and Vehicle-Infrastructure Integration (VII) in the US, SMARTWAY and Vehicle Information and Communication System (VICS) in Japan, and European R&D activities within the framework of i2010: Intelligent Car Initiative - e.g., PReVENT, CVIS, and SAFESPOT. Related standardization activities include Continuous Air Interface for Long and Medium Range (CALM) to set up a stable, globally compatible regulation framework enabling higher market impact. The Car2Car Communication Consortium (C2C-CC) supports an open, interoperable industry standard for vehicular communication based on wireless local area network (WLAN) technologies pushing for specific frequency band allocation at 5.9 GHz for critical automotive safety. This paper shows CyberCars-2’s cooperative Cybernetic Transport System (CTS) architecture compatible with C2C-CC and CALM achievements. SAFESPOT for architecture design was adopted after meeting cooperative systems benefits, i.e., improving traffic safety for more efficient logistics and response to hazards and accidents, improved road network management and control and shorter, more predictable journey times.

Abstract:

Quorum sensing is a cell-to-cell communication system that exists widely in the microbiome and is related to cell density. The high-density colony population can generate a sufficient number of small molecule signals, activate a variety of downstream cellular processes including virulence and drug resistance mechanisms, tolerate antibiotics, and harm the host. This article gives a general introduction to the current research status of microbial quorum-sensing systems, focuses on the role of quorum-sensing systems in regulating microbial resistance mechanisms, such as drug efflux pump and microbial biofilm formation regulation, and discusses a new strategy for the treatment of drug-resistant bacteria proposed by using quorum quenching to prevent microbial resistance.

Abstract:

The indirect adaptive regulation of unknown nonlinear dynamical systems with multiple inputs and states (MIMS) under the presence of dynamic and parameter uncertainties, is considered in this paper. The method is based on a new neuro-fuzzy dynamical systems description, which uses the fuzzy partitioning of an underlying fuzzy systems outputs and high order neural networks (HONN's) associated with the centers of these partitions. Every high order neural network approximates a group of fuzzy rules associated with each center. The indirect regulation is achieved by first identifying the system around the current operation point, and then using its parameters to device the control law. Weight updating laws for the involved HONN's are provided, which guarantee that, under the presence of both parameter and dynamic uncertainties, both the identification error and the system states reach zero, while keeping all signals in the closed loop bounded. The control signal is constructed to be valid for both square and non square systems by using a pseudoinverse, in Moore-Penrose sense. The existence of the control signal is always assured by employing a novel method of parameter hopping instead of the conventional projection method. The applicability is tested on well known benchmarks.

Abstract:

Observer-based adaptive fuzzy H∞ control is proposed to achieve H∞ tracking performance for a class of nonlinear systems, which are subject to model uncertainty and external disturbances and in which only a measurement of the output is available. The key ideas in the design of the proposed controller are (i) to transform the nonlinear control problem into a regulation problem through suitable output feedback, (ii) to design a state observer for the estimation of the non-measurable elements of the system's state vector, (iii) to design neuro-fuzzy approximators that receive as inputs the parameters of the reconstructed state vector and give as output an estimation of the system's unknown dynamics, (iv) to use an H∞ control term for the compensation of external disturbances and modelling errors, (v) to use Lyapunov stability analysis in order to find the learning law for the neuro-fuzzy approximators, and a supervisory control term for disturbance and modelling error rejection. The control scheme is tested in the cart-pole balancing problem and in a DC-motor model.

Abstract:

Distribution systems for broadcasting, Press and Internet journalism are converging: the same infrastructure can deliver all three historically separate services. Reception devices mirror this: the Connected TV, the tablet and the smart phone overlap in their functionality. Service overlaps are evident too, with broadcasters providing online and on-demand services and newspapers developing electronic versions. Does this mean that media regulation policies must converge too? My argument is that they should, though only where historically different communications are now fulfilling a similar function, e.g. broadcaster online services and electronic versions of newspapers. Convergence requires a degree of harmonisation and, to this end, I advocate a review of UK broadcasting’s ‘due impartiality’ requirement and of the UK’s application of the public service concept. I also argue for independent self-regulation (rather than state-based regulation) of non-public-service broadcasting journalism. These proposals are UK-specific since, given the regulatory and cultural differences between countries, detailed policy changes are likely to be determined mainly at national level, but I note the wider European context. Moreover, the underlying principle is relevant internationally: as freedom of entry into the non-public service sector of broadcast and online journalism becomes closer to the historically much greater freedom of entry into the Press, so the regulation of freedom of expression in these converging fields should become more consistent – and, I would argue, less state-based.

Abstract:

The distributed robust output regulation problem for multiagent systems is considered. For heterogeneous uncertain linear systems and a linear exosystem, the controlling aim is to stabilize the closed-loop system and meanwhile let the regulated outputs converge to the origin asymptotically, by the help of local interaction. The communication topology considered is directed acyclic graphs, which means directed graphs without loops. With distributed dynamic state feedback controller and output feedback controller, respectively, the solvability of the problem and the algorithm of controller design are both investigated. The solvability conditions are given in terms of linear matrix inequalities (LMIs). It is shown that, for polytopic uncertainties, the distributed controllers constructed by solving LMIs can satisfy the requirements of output regulation property.

Full text

Abstract:

Signalling in multicellular organisms is mediated by complex networks that integrate extracellular and intracellular signals to generate appropriate responses regulating cell proliferation, differentiation and survival. Downstream of many cytokine and growth hormone receptors, receptor-associated JAKs (Janus kinases) activate transcription factors of the STAT (signal transducer and activator of transcription) protein family and thereby mediate signal transduction from the plasma membrane to the nucleus. The JAK/STAT pathway has been shown to be constitutively activated in a wide array of human malignancies. To elucidate mechanisms contributing to tumour formation and identify system properties of the JAK/STAT signalling pathway, a systems biology approach can be employed. So far the majority of studies available have focused on down-regulation of the signalling pathway based on simulations. However, a data-based model of the core module of the JAK2/STAT5 signalling pathway showed that rapid nucleocytoplasmic cycling of STAT5 is an essential pathway property. In the future, combining assays for quantitative analysis at different levels will be important to gain deeper insight into molecular mechanisms regulating intracellular communication mediated by such complex dynamic systems as signalling pathways and their targets.

Abstract:

Transparency is now a fundamental principle for data processing under the General Data Protection Regulation. We explore what this requirement entails for artificial intelligence and automated decision-making systems. We address the topic of transparency in artificial intelligence by integrating legal, social, and ethical aspects. We first investigate the ratio legis of the transparency requirement in the General Data Protection Regulation and its ethical underpinnings, showing its focus on the provision of information and explanation. We then discuss the pitfalls with respect to this requirement by focusing on the significance of contextual and performative factors in the implementation of transparency. We show that human–computer interaction and human-robot interaction literature do not provide clear results with respect to the benefits of transparency for users of artificial intelligence technologies due to the impact of a wide range of contextual factors, including performative aspects. We conclude by integrating the information- and explanation-based approach to transparency with the critical contextual approach, proposing that transparency as required by the General Data Protection Regulation in itself may be insufficient to achieve the positive goals associated with transparency. Instead, we propose to understand transparency relationally, where information provision is conceptualized as communication between technology providers and users, and where assessments of trustworthiness based on contextual factors mediate the value of transparency communications. This relational concept of transparency points to future research directions for the study of transparency in artificial intelligence systems and should be taken into account in policymaking.

Abstract:

The article considers the role of the Internet as one of the channels for promoting products. The article is aimed at developing practical recommendations as to the organization of communication policy on the Internet through the creation of an online store, sales via marketplaces, also with the use of cashback. Modern trends of e-business are generalized, characterizations of online trading, its advantages for buyers and sellers are provided. It is proposed to organize interaction with customers in two sectors: marketplace and online store. The main features of the marketplace and the online store (from the point of view of sellers / suppliers) are systematized: the main goal, participants, interaction with buyers, the need to create a website, functionality, creating a profile, control, product range, price regulation, advertising costs, working conditions, earnings, the ability to develop systems of repeated sales, the number of sellers. The main disadvantages in operating a marketplace and an online store (either from the point of view of sellers or from the point of view of buyers) are considered. The article generalizes the procedure for organizing a communicative policy on the Internet (through the store’s website), which envisages: creating an online store, interacting with customers through the online store sales. The procedure for organizing a communicative policy on the Internet (through the marketplace) is described, including: entering the marketplace, selling products to buyers, paying a commission for the products sold and paying a standard monthly fee for using the platform. It is recommended to form a communication policy using the cashback service and the following technology: registration in the cashback service, carrying out the purchase of products through the cashback service catalog (by links), transferring data about the purchase of an online store or marketplace, payment of cashback service commission, payment of cashback to the buyer. The main shortcomings of cashback (from the point of view of sellers and from the point of view of cashback services) are considered, which include the taxation of cashback in the amount of 19.5% for individuals and VAT, provided that both participants of the bonus program are legal entities. The main disadvantages of cashback from the position of buyers are considered.

Abstract:

Digitisation, international agreements, converging services, proliferating platforms and the prospects of additional services are all affecting the conduct of media regulation worldwide, transforming the ways media regulation is considered and debated by scholars, activists and players alike. In these circumstances, the range of institutions concerned with media regulation has expanded. Important policy innovations are just as likely to be recommended by the Productivity Commission in its inquiry into broadcasting regulation or the High Court in its decision to count New Zealand content as Australian content as they are to be made by relevant departments and authorities with carriage for broadcasting regulation. These new circumstances, which can also be seen in the various European Union directives affecting national broadcasting systems in Europe, can be viewed as part of a wider challenge to normalise media regulation. While normalisation of the media industries is by no means assured, what has happened is that the cultures within which media regulation is discussed and debated are changing profoundly.
