Modern scientific and technological development of society, further intensification of production together with the provision of proper safety of human life and preservation of the environment necessitate the search for new solutions in the creation of new materials and technologies. The creation of effective materials for the latest and future technologies and technicaldevices is based on new scientific data on the definition and analysis of specific mechanisms of physicochemical processes that implement the desired structural and phase state of solids with the desired set of properties. In recent decades, the most effective way to control the properties of solid materials is the use of nanotechnology and nanomaterials, which have recently been increasingly used in almost all areas of new technologies. The article investigates synthesis processes, structural characteristics and structural-phase processes in multicomponent metal-ceramic oxide materials, physicochemical mechanisms ofsynthesi s of multielement oxide compounds Y2Zr2O7 with pyrochlor structure during consolidation and sintering of yttrium and zirconium oxides, structure formation -phase characteristics of materials with different chemical composition. The structural-phase evolution in the synthesis of new substances and the consolidation of compounds of the Y2O3 – ZrO2 system have been studied. Samples of oxide heat with the proportion of pyrochlorine phase Y2Zr2O7 up to 41 % were obtained. It is established that the kinetics of increasing the proportion of pyrochlorine phase in the samples indicates a desirable increase in the activity of the chemical reaction, which can be achieved by increasing the synthesis temperature to the temperatures of eutectic formation or increasing the reaction surface of powders.

In the chapter it is argued that both capital accumulation and technological development need each other, but are also conditioned and defined by each other. In practice, this entails that technology and its development, in capitalism, are about endlessly producing and marketing new technologies involving a profit motive. In other words, in this organization, technology and its development do not have a purpose apart from the creation of monetary value. This modern-day assembly is framed in the chapter as a capital-technology alliance to highlight the intertwined relation of capital accumulation and technological development, and how they both produce conditions for alienation. This is because both of them contribute to a lack of control and freedom in personal and communal lives, albeit in somewhat different ways, and generate personal and communal detachment from fellow humans and from the rest of living nature.

Purpose. The main purpose of the article is the analysis of the phenomenon and manifestations of the somatic transformations in the context of anthropo-technological evolution at the beginning of the XXI century. Theoretical basis. The author determines the understanding of the concept "somatic transformations" in the frames of anthropotechnogynesis is possible only on the base of integrative approach and combination of post-non-classical scientific paradigm methodology, theory of the technological development, ideas of trans-humanism, informative society concepts, and net technologies influence on the identity of the human being with robots in the sphere of bioethics and nanoethics, the ethics of new technologies and legal documents which are regulating the processes of technotransformation of the human being. Originality. The author has proved on the example of analysis of the somatic transformations own psychosomatics as he solves some important global in the context of anthropotechnogynesis that a person with help of technological enlargement of and branch problems, so he is trapped of alienation in the very crucial stage, loses the identity and crashes the corporeality in his self. Conclusions. As evidenced by the given analysis, at the modern stage the anthropotechnogynesis is followed by the large-scale quantitative and qualitative somatic transformations based on NBIC-convergence, as a result, a new anthropological subspecies – Homo technologicus appears. All these transformations are a regular stage of evolution, which confirms the thesis of the essential and functional connection of technology with the human body, which are in a relationship of "mutual provocation". In the base of the paradigmatic ontological and anthropological shift which has been on the modern stage, lies the idea of continuity of anthropotechnological co-evolution of the human body and its environment which projects itself in psychosomatic human structure, making a transformation program for better adaptation in technonanobeing. The convergence of human life and techno-existence is a platform for somatic transformations. They are divided into two main groups: intra-structural, substantial, related to techno-modification of the human body directly through biotechnology and genetic engineering, cyborgization, xenotransplantation, Hi-Hume connection with Hi-Tech and others, and external-contextual, when under the influence of pancommunication and hybridization the environment is increasingly mentalized and somatized, and modern technologies are gradually transformed into the social body of man.

The article is theoretical and methodological. It describes the concept of artificial intelligence. It has been outlined how over the years AI is slowly replacing human work. Artificial intelligence is new technologies that appear in every area of human life. You don’t have to look far for examples, digital network operator, smart air conditioning, online shopping, connected vacuum cleaners, robots used in factories. The aim of the work is to show how dangerous artificial intelligence can be for humans. It may lead to the fact that in a few or a dozen years or so some professions will disappear. Where human work is a repetitive activity, it will be replaced by a machine. Technological development has transformed the typewriter into a computer, we already have ma- chines that can learn. It would be necessary to ask what will happen in a dozen or so years, how far will this avalanche of technological progress go. New technologies require careful management. The paper describes how new technologies affect the work of accounting offices. It has been indicated which accounting activities can be completely taken over by the machines. Several hypotheses are presented in the paper. The first is the recognition that data entry into accounting systems will be automated and taken over by new technologies. The second thesis assumes that the profession of accountant will change, it will change but will not disappear. Another one assumes that new technologies in the public law circulation will create the basis for calculating taxes by the tax administration.

The article considers the possibility of introducing digital and intelligent systems in the electric power industry, including the analysis of the consequences after the introduction of new technologies on the economic, social and technological side. Currently, the concept of distributed generation is being used more and more often in the global energy arena. This is certainly a trend in the energy sector. The current level of technological development in the energy sector is quite high, but in order to continue to increase competitiveness, we need a further transition to digital and intelligent energy systems that will increase the reliability, quality, environmental friendliness and automation of energy supply.

Technological devices are becoming more and more integrated in the management and control of traffic in big cities. The population perceives the benefits provided by these systems, and, therefore, citizens usually have a favorable opinion of them. However, emerging countries, which have fewer available infrastructures, could present a certain lack of trust. The objective of this work is to detect the level of knowledge and predisposition towards the use of new technologies in the transportation field of the Dominican Republic. For this study, the National Survey on Mobility was administered to a sample of Dominican citizens, proportional to the ONE census and to sex, age and province. The knowledge of ITS topics, as well as the use of mobile applications for mobility, are scarce; however, there was a significant increase that can be observed in only one year. Moreover, technology is, in general, positively assessed for what concerns the improvement of the traffic field, even though there is a lack of predisposition to provide one’s personal data, which is necessary for these devices. The process of technological development in the country must be backed up by laws that protect the citizens’ privacy. Thus, technologies that can improve road safety, mobility and sustainability can be implemented in the country.

This article considers processes of environmental racialisation in the postgenomic era through their politics of difference and poetics of influence. Subfields like epigenetics promise to account for a plurality of possible influences on health outcomes. While this appears to present possibilities for historical reparation to communities whose epigenomes may have been chronically altered by histories of violence and trauma, the prevailing trend has been to compound processes of racialisation in the reproduction of good/bad environments. The postgenomic era has promised an epistemological transformation of ideas and values of human life, but its practices, technologies and ideology have so far prevented this. Epigenetics, rather, reproduces biomedical exclusions through imaginaries of embodied contexts, methods of occlusion and hypervisibility, and assignations of delay and deviance. This is more complex than both genetic reductionism and environmental racism: studies on epigenetics reveal a poetics of influence at work under liberal humanism complicit in the creation of death-worlds for racialised populations. Other experiments with life are possible and unfolding: Jay Bernard’s poem ‘Chemical’, set in the aftermath of London’s Grenfell Tower fire in 2017, unmoors its bodies from material environment, offering a spectral configuration of collective life. This configuration involves negotiating with the fixing of time and space on which genomic imaginaries depend.

This study examined the importance of technologies in advancing modern organizations’ corporate social responsibility (CSR). Drawing upon environmentalist and technological theories, we analyzed the shift from the traditional development of technology to the development of sustainable technologies for the further sustainable advancement of organizations. Technology has decisively influenced the development of humankind, but its research has traditionally excluded sustainable development issues. Newer technological visions have addressed the incorporation of technologies in all industries more comprehensively to solve social issues related to environmental protection and sustainable economic development. Such an orientation is followed by several conceptual solutions, such as the sustainable use of traditional technologies, development of sustainable technologies, and interdisciplinary treatment of sustainable technology to extend the CSR model. The results of our study have theoretical implications, highlighting the effects of technological development and new technologies on the course of further societal sustainable development. Practical implications include extending CSR’s Triple Bottom model with a technological dimension to improve organizations’ further sustainable operating and behavior.

The broadcasting world is currently undergoing a revolution. The new technologies of cable and, more importantly, satellite broadcasting have brought within reach an enormous potential expansion and diversity in broadcasting. The Broadcasting Act 1990 is the government's response to the challenge, creating a mostly new regulatory framework. Alongside technological advance there has been a growing concern with regulating programme quality, as the creation of the Broadcasting Standards Commission (placed by Pt. V of the Act on a statutory footing) bears witness. A minor, but not insignificant, place in these cross-currents of ferment is occupied by religious broadcasting. This article seeks to place the controls and duties relating to religious broadcasting under the new regime within the context of its history in the UK and to consider the extent to which the new legal and administrative controls achieve an acceptable balance between religious expression and control of standards.

This book documents the rise of digital repression—how governments are deploying new technologies to counter dissent, maintain political control, and ensure regime survival. The emergence of varied digital technologies is bringing new dimensions to political repression. At its core, the expanding use of digital repression reflects a fairly simple motivation: states are seeking and finding new ways to control, manipulate, surveil, or disrupt real or perceived threats. This book investigates the goals, motivations, and drivers of digital repression. It presents case studies in Thailand, the Philippines, and Ethiopia, highlighting how governments pursue digital strategies based on a range of factors: ongoing levels of repression, leadership, state capacity, and technological development. But a basic political motive—how to preserve and sustain political incumbency—remains a principal explanation for their use. The international community is already seeing glimpses of what the frontiers of repression look like, such as in China, where authorities have brought together mass surveillance, online censorship, DNA collection, and artificial intelligence to enforce their rule in Xinjiang. Many of these trends are going global. This has major implications for democratic governments and civil society activists around the world. The book also presents innovative ideas and strategies for civil society and opposition movements to respond to the digital autocratic wave.

The article is devoted to the study of economic contradictions related to the use and transfer of dual-use goods and technologies. The article highlights different approaches to defining the categories «technology» and «dual-use technology». Types of dual-use technologies are outlined. The main economic contradictions related to the use and transfer of dual- use goods and technologies are identified: 1) contradictions related to the creation of new technologies that can be both useful in the civilian and military spheres; 2) contradictions related to the manufacture and use of dual-use goods; 3) Contradictions are related to the creation of new means of production that can be used both for the production of civilian goods and for CBRN; 4) contradictions in the use of technological processes for the civilian and military spheres; 5) contradictions related to the development of transport and improvement of methods of delivery of CBRN; 6) contradictions between the interests of economic development of different countries on the basis of the introduction of new technologies and non-proliferation of CBRN; 7) interstate political and economic contradictions regarding the CBRN; 8) contradictions between groups of countries and individual countries regarding the non-proliferation of CBRN; 9) contradictions related to environmental pollution in the process of manufacturing and testing of CBRN; 10) contradictions in the realization of economic and political interests between countries that have modern weapons of mass destruction and countries that do not possess these weapons; 11) contradictions regarding the protection of their national interests etc. The peculiarities of the transfer of dual-use goods and technologies in the modern economy are shown and it is determined that it acquires a network character. The need to apply export controls to the transfer of dual-use goods and technologies is emphasized.
