Influences of viral marketing in social networking sites on consumerism
Authors: Wong Krystle Jiajing
Published: September 2021

SNSs being a widely used online interaction tool have led to the widespread of online marketing strategies such as viral marketing. While interacting on SNSs, SNSs users tend to have the need to portray an ideal-self to gain positive social feedback, hence, the need to consume and purchase items or in restaurants and cafÃ©s promoted on viral marketing posts. Therefore, this study aims to look into factors influencing consumerism in the context of viral marketing on SNSs. Qualitative research method was implied based on Social Comparison Theory, Impulse Buying Theory and Affluenza Compulsive Buying Theory and interview was conducted on seven in-college youths in the area of Klang Valley. Eight main factors behind the influences of viral marketing in social networking sites have been identified, while two main qualities of consumerism were mainly discussed in this theory. Limitations were taken into account in terms of demographic and geographic as well as methodology. Future researchers are suggested to conduct a study with an equal number of both genders and at alternative geographical area using quantitative methodology for a more generalized and impactful results on other factors of viral marketing influencing consumerism. This study provides an insight for SMEs on the low-cost viral marketing through SNSs which promotes consumerism through rapid response rate. Socially, consumerism is also related to bankruptcy. This study would be one of the pioneer studies in Malaysia which looked into consumerism through viral marketing on SNSs, contributing to local context literature as well as from the context of SNSs which was not thoroughly studied by past researchers.

Hate Speech in Readers’ Comments and the challenge of Democratic Consolidation in Nigeria: A Critical Analysis
Authors: Targema Tordue Simon , Lucas Joseph M
Published: September 2021

Hate speech is among the most significant communication issues that preoccupy the agenda of relevant governmental agencies and media analysts in contemporary Nigeria. It is an unfortunate phenomenon that manifests in the public sphere, and is fast threatening the fragile democracy which the country is struggling to consolidate. Against this backdrop, this study investigates the nature of readers’ comments on online news sites in the country, their place within the context of hate speech rhetoric, and their implication on democratic consolidation in the country. Hinged on the Social Responsibility Theory, the study employs two research methods- Critical Discourse Analysis (CDA) and content analysis to investigate the manifestation of hate speech in online readers’ comments. Population of the study comprises 2,530 comments, generated from ten stories on prominent online news platforms in the country. From these, a sample of 250 comments (10% of the population) has been selected systematically for closer examination. Findings reveal that, although quantitatively, positive comments dominate the study population (comprising 60% while negative comments account for the remaining 40%), qualitatively, the trend of discussion is disturbing, as commentators employ the use of hate language, verbal assault, name calling, insults and derogatory words to describe subjects. To this end, the study concludes that readers need to exhibit a high sense of responsibility in the course of interaction on the online comments platforms. Where such responsibility is not self-enforced by commentators, news platforms should remove comments that contain venomous hate language in the interest of national unity, democracy and development.

Journalists are groups that are important in helping to provide information to the public. The development of communication technology has triggered a concept of Mobile Journalism or MoJo in the journalistic world. This study will show the application of the MoJo concept in the Kosmo Online and Rotikaya news portal that are able to change the working style of journalists from time to time. This study aims to see MoJo trends capable of changing the style of journalists, MoJo skills used among media practitioners and the future of newspaper companies as a result of digital technology. This study used a qualitative method that is through a deep interview with two informants fromboth media organisations. The theory used in this study is the Diffusion of Innovation Theory by Everett Rogers that examines four important elements of social system, time frame, innovation and communication channels. As a result of this research, researchers have found some new findings that are classified according to the theoretical elements applied in the MoJo concept. The findings show that both interviewed media organizations have successfully applied MoJo concepts in journalist working style. MoJo is able to change the style of journalist work from traditional style to modern style by using mobile devices to report the news. This application has helped journalists improve their skills indirectly towards the structure of news writing with the use of technology in delivering news visually. This MoJo has also been delivering the news that there is no obstacle to the gatekeeper where the true information continues to be communicated to the public without restrictions. This explorative study can be the basis of the journalistic field in today is growing digital era.

Malay Editorial Cartoons in the 1930s: Humour and Sarcasm in Visualising the Other
Authors: Merican Ahmad Murad
Published: September 2021

This article defines Malay identity through their portrayal of the Malay Other - the Arabs, Indian Muslims and the Europeans. The Arabs and Peranakan Arabs were identified as foreigners in disguise, the Europeans colonisers as harbingers of modernity. From this perspective not much have been written, using editorial cartoons in Malaysia. This article then focuses on the depiction by the Malay of what constitutes the foreigner (and the West). The medium of the cartoon was a recent innovation in Malay-language newspapers, having first appeared in the first issue of Warta Jenaka a weekly pictorial newspaper on 7 September of 1936. This article surveys three major periodicals in the 1930s including that of Warta Ahad and Utusan Zaman in their construction of ambivalence toward colonialism and Western influence. These were the inter-war years. The periodicals capture Malay sentiments couched in humor and sarcasm ranging from the proximate culture of the Arabs to British or European notions of race, modernity and progress. It is cognizant of the colonial condition and the milieu and the inherent character of the Malay press, serving as instruments of criticism and satire. The visual ethno- nationalistic discourse is observed with regard to the trajectory of modernity brought into Malay awareness during the period.

Published: September 2021

Corruption is an important problem affecting every strata of the Nigerian society. Its impact on Nigerian media is no exemption. Corruption in relation to media is popularly tied to brown envelope which ultimately affects journalist sense of news judgment. Hence, this paper took a theoretical approach to examining the relationship between the issue of brown envelope syndrome and unethical practice within the Nigerian media system and its implications on ethical and socially responsible journalism. Surprisingly, result of the literature reviewed revealed that poor journalistic training and lack of professionalism is responsible for unethical practice in Nigerian media. It further revealed loss of credibility, loss of watchdog roles and decline in news quality, values and public trust of journalists as its implications on ethical and socially responsible journalism. The paper recommend among others, that sound education in form of regular seminars, workshops and professional trainings be given to would-be journalists where legal framework and media regulatory bodies served their responsibilities by regularly checkmating the excesses of journalists to confirm strict adherence to ethical codes.

Published: September 2021

Tom and Jerry has already celebrated its Platinum Jubilee as it was produced firstly in 1940 and bit by bit Tom and Jerry has been dominating the watch-lists of the cartoon lovers from all over the world by retaining itself as one of the most popular cartoons of all time. But it is not only the never-ending rivalry between the cat and the mouse with the slapstick comedy that helps the cartoon to be as one of the talked of the topics in the entertainment and media industry, it has created some controversies regarding its contents; and violence is one those that has made the scholars and critics talk about it and its possible impacts on the audience. Apart from lamenting for the impacts of violence on the juveniles’ mind, this study rather focuses on how Tom and Jerry projects violence alongside with the slapstick comic elements in the name of entertainment since it is significant to discern what violence is and then categorize them into different type as different categories of violence may have impact on the audience in different ways. By defining the term violence, this study shows how Tom and Jerry displays the actions which can be the ribs and stretchers of the umbrella known as violence. Whereas most of the scholars concentrate on the outcome of showing violence among the different programs in media, this study categorizes the actions performed by the characters in the cartoon into different categories through a qualitative content analysis method and defines those actions according to the definitions of violence.

Literary Castles of Europe and the Russian “Country House Genre” across the Centuries (1880s–1930s)
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Dmitrieva Ekaterina E.
Published: September 2021

The proposed book is devoted to a comparative study of the Russian Country House and the Western European castle as real artefacts of everyday life and culture, and, in particular, to the literary phenomenon to which these gave rise: the “country house genre” (usadebnaya kul’tura) in Russia, and literary castles (châteaux littéraires) in the West. The time frame of the study covers the late nineteenth century through to the first three decades of the twentieth. A few essays in the collection do, however, look back to Ancient Regime and Revolutionary France, as well as forward to more recent iterations of the topic in post-war literature. The book is divided into five parts. In the first part, attention is mainly given to the processes that took place on the Russian estate after the revolution of 1917, namely, the mass extermina- tion of Russian estates and the almost total emigration of their inhabitants. In this connection, two noteworthy attempts to revive the estate life in exile (Rachmaninov’s and Bunin’s) are con- sidered. The second part of the book is devoted to the theme of artist colonies, communes and dachas, beginning with Redhouse, home to the famous artistic utopia of the Pre-Raphaelites (England), the artist commune of Worpswede (Germany), among others. In part three, the coun- try house (castle) is viewed as an initiation space. This theme can be traced through material and examples relative to both historical (Versailles, Wörlitz, La Chennais estate, Quinta da Regalei- ra, Dornach) and “literary estates” (the texts of Bastide, Beckford, Byron, the Duchess of Duras, Stendhal, J. Gracq, etc.). The fourth part of the book is devoted to the history of manor styliza- tions — architectural, pictorial and literary. Examples here include: G. Walpole’s Strawberry Hill, T. Reinach’s Villa Kerylos, A. Benois’s watercolours of Versailles, the novels of Boylesve and Kundera. The main focus of the last part of the book is the phenomenon of the castle in Western Europe as a space for so-called ‘life creation’ (the castles of Marquis de Sade, Madame de Staёl, M. Proust, F. Mauriac and A. Vyazemsky). The publication is intended both for specialists (academics, teachers, research students and undergraduates) and for the general reader interested in the place of the Russian country house in literature and culture.

Corporate governance and the cost of equity: Evidence from the developing country
Authors: Odat Mahmoud A. , Al Daoud Khaldoon Ahmad , Zurigat Ziad Mohammad
Published: September 2021

This study examines the impact of corporate governance mechanisms on a firm’s cost of equity. The corporate governance mechanisms examined consist of board size, board independence, CEO duality, multiple directorships held by board members, and board political influence. To accomplish the study objective, 210 firm-year observations for manufacturing companies listed on Amman Stock Exchange (ASE) in the period 2014–2018 are analyzed using panel data analysis techniques. The results of the fixed effects regression model reveal that CEO duality and board political influence negatively affect the cost of equity, while there is no significant effect of board size, board independence, and multiple directorships on the cost of equity. The results suggest that firms’ board of directors is an important factor in mitigating the agency problem suggested by Jensen and Meckling (1976). They also suggest that information risk is priced, which is consistent with previous research such as Easley, Hvidkjaer, and O’Hara (2002), and that the board of directors plays a role in reducing that risk in capital markets.

Published: September 2021

The global climate models predict changed precipitation patterns with frequent episodes of drought. Scarcity of water is a severe environmental constraint to plant productivity. Plants display a variety of physiological and biochemical responses at cellular and whole-organism levels towards prevailing drought stress. This study included container experiments with three flower crops aster (Callistephus chinensis), helichrysum (Helichrysum bracteatum) and echinacea (Echinaceae purpurea). Drought was simulated by reducing the number of watering’s to field capacity from 25–30 to 85–90 %. Three levels of watering were studied - three times, twice and once a week. The results showed that the cultivation of ornamental plants in containers under reduced watering conditions (twice or once a week) for a period of 3 months led to considerable inhibition of growth and even to plants death. The relative water content and the level of electrolyte leakage vary depending on the weekly number of waterings. The highest values of electrolyte leakage were reported in a single watering for aster -5107.1µS / g, for helichrysum -8314.9 µS / g and for echinacea -3722.8 µS / g. The high rates of conductivity, especially with one-time weekly watering, are evidence of the damage caused by the simulated water stress. This corresponds to the reported low percentages of RWC % and the low values for the height and diameter of the plants. The relative water content in plant tissues decreases depending on the irrigation regime. The lowest values for aster, helichrysum and echinacea were again observed in the variant with a single weekly watering, respectively 15%, 11.5% and 15.8%.

Published: September 2021

The aim of this research was to establish the influence of two tillage systems: one without ploughing, and one with conventional tillage, upon soil microorganisms. The experiment was carried out on the farm of Brezovo, in two variants - control, with applied conventional tillage and a second variant – without ploughing, on an area of 200 dk for each variant. The soil type of the field is sandy - clay, with medium to high cation exchange capacity. The nitrate nitrogen content was determined colometrically and spectrophotometrically for phosphorus and potassium. The ratio of carbon to nitrogen was measured twice - before sowing and during harvest time. The amount of total bacterial and fungal microflora, as well as the ratio of active bacteria and fungi was monitored. Based on the obtained results, it was found that the numbers of the total bacteria and fungi is higher in the variant without ploughing, compared to the control sample. The same trend is maintained in the quantitative ratio of active fungi and bacteria. Reduced tillage systems create better conditions for the development of the studied groups of microorganisms, compared to conventional cultivation technologies.

Modern robots perform a number of comprehensive tasks. In the agricultural sector, they are able to work on large areas with a wide range of crops with different agronomic requirements. They are highly maneuverable, some of them have the ability to rotate around its axis (can work in hard to reach places and small terrains). In the beginning, agricultural robots were slow, light and small. At the same time, they could not fully meet the requirements of their „employers“ due to the comprehensiveness of agricultural activity and the level of development of scientific and technological progress. The tasks of the agrorobots will only increase - from data collection, weeding, performing various agrotechnical activities to offering many functions. The present article uses the famous TRIZ theory, developed by the Soviet inventor Henrik Altshuler. Its basic principle is the resolution of an unresolved contradiction by means of an inventive solution, if any. An unresolved inconsistency occurs if, when one parameter improvement is introduced into a system, another parameter deteriorates. These contradictions are called „technical contradictions“. The overall dimensions of an agricultural robot for growing some crops have been determined.

Authors:   Agricultural University-Plovdiv, Dimova Delyana
Published: September 2021

Information concerning poultry farming (chickens, ducks, geese and guinea fowls) is the object of study in the current paper. It has been extracted from the website of the Food and Agriculture Organization of the United Nations. The obtained data about the four Balkan countries (Bulgaria, Greece, Romania and Albania) have been saved in a separate Excel file. Subsequently, they have been processed and evaluated. The surveyed period includes 58-year time interval from 1961 to 2018. The article presents the dependencies in the development of poultry farming in the listed countries for the indicated period. A comparative analysis and an analysis of variance have been applied to the considered data. The examined information has also been summarized and presented mainly in graphical form. The results of the analysis showed the relevant time intervals in which a continuous growth, as well as a significant decline of the studied indicators (number of chickens, number of ducks, number of geese and guinea fowls) was established for each of these four Balkan countries. The statistical assessment of the number of chickens in the examined countries formed three groups with statistically significant differences. Data for Albania were excluded from the evaluation of the other two indicators because the provided information about them was for the period from 1994 to 2011.

In 2020 a field experiment was conducted with mutant lines of common bean from M4 generations at the Maritsa Vegetable Crops Research Institute, Plovdiv. The aim of the study was to determine the productivity of plants in drought conditions. Twenty four mutant lines were studied in two variants: optimal (non-treated) and reduced (treated) irrigation regimes. A description of the mutant lines was made according to the following features: color: coloring of the flag; beans - length without beak; bean shape in cross section (through the seed); beans-basic coloring; flowering time. Phenological data were collected for phenophases: budding, flowering, fruit size, consumption and botanical maturity. At consumption maturity, biometric measurements were made of 5 plants per repetition on the following indicators: fresh weight (g) of a plant; number and fresh mass (g) of green beans per plant; length (cm) and width (cm) of beans, total fresh biomass (g). The highest productivity found among the treated plants in consumption maturity were the early mutant lines M 564-193-9-1-1 and 564-193-9-1-2, followed by M 564-190-1-1-1, M 564-110-1-2, and M 564-191-1-1-2, compared to the parent line L 564 and all the rest of early mutant lines. The treated plants developed the phenophases 7-10 days later than those with optimal watering.

The Internet of Things (IoT) has become increasingly popular in the recent decade. The Internet of Things helps people live and work smarter, as well as gain complete control over their lives. The concept of the IoT went widely into practice in different fields – Infrastructure, Production, Healthcare, Banks, Smart cities, Insurance, Media, Retail, Connected homes / Smart buildings, Agriculture, and many more. Modern agriculture can show its potential and importance by using these innovative technologies. The measuring devices, ensuring the transformation of data for the external environment into machine-readable data, at the same time filling the computing environment with significant information are very important. A wide range of measuring devices is used, from elementary sensors (e.g. temperature, pressure, illumination), consumption meters (e.g. smart meters) to complex integrated measuring systems. Satellites, drones, wireless sensor networks, analytical farming devices systems, farm management systems, big data applied to the farm are very useful and applicable in smart farming. The Internet of Things is a huge opportunity for farmers to monitor their crops and increase productivity, to monitor their livestock, to manage all the processes in their work and to take decisions at the right time. The article analyzes issues related to the modern IoT methods and their usage in general and in the area of agriculture. The main goal is to analyze the current state of IoT and its potential in areas of rural development and agriculture in the Republic of Bulgaria.
Influence of foliar fertilizer Panamin Agro on the growth and decorative characteristics of Tagetes species in leaf application
Authors:   Agricultural University-Plovdiv, Ivanova Valeria
Published: September 2021

Species of the genus Tagetes are some of the most common plants in gardening practice in Bulgaria. One of the key problems in the production of planting material of these species is the slow growth of seedlings in the beginning of their cultivating. The application of foliar fertilizers is one way to solve this problem. This study examines the impact of foliar fertilizer Panamin Agro on growth processes and biometric characteristics of three species of tagetes: T. erecta L.; T. patula L.. and T. signata Bartl. Foliar fertilizer Panamin Agro was used in 3 different concentrations: 0.5%; 1.0% and 1.5%. The treatment started with the formation of the first true leaf in 90% of the cultivated plants and was applied every 14 days three times until the seedlings were taken outdoors and planted in a permanent place. It was found that the growth characteristics of the treated plants exceed substantially those of the untreated control plants. With the highest and thickest stems of plants, the highest number and size of leaves and flowers and accelerated, enhanced and prolonged the period of photosynthesis are three species of tagetes treated with 1.0% PanaminAgro. Treatment with a concentration of 1.5% does not always have a positive effect on the growth characteristics of the treated plants. The effect of leaf treatment with PanaminAgro on the biometric characteristics of the root system is insignificant. We offer the use of PanaminAgro in the nursery practice in the production of planting material of african marigold in a concentration of 1.0%.

Published: September 2021

A multidisciplinary approach based on experiments and mathematical modeling was used in biomimetic system development for three-dimensional (3D) cultures of cancer cells. Specifically, two cancer cell lines, human embryonic teratocarcinoma NT2/D1 and rat glioma C6, were immobilized in alginate microbeads and microfibers, respectively, and cultured under static and flow conditions in perfusion bioreactors. At the same time, chemical engineering methods were applied to explain the obtained results. The superficial medium velocity of 80 ?m s-1 induced lower viability of NT2/D1 cells in superficial microbead zones, implying adverse effects of fluid shear stresses estimated as ?67 mPa. On the contrary, similar velocity (100 ?m s-1) enhanced the proliferation of C6 glioma cells within microfibers compared to static controls. An additional study of silver release from nanocomposite Ag/honey/alginate microfibers under perfusion indicated that the medium partially flows through the hydrogel (interstitial velocity of ?10 nm s-1). Thus, a diffusion-advection-reaction model described the mass transport to immobilized cells within microfibers. Substances with diffusion coefficients of ?10-9-10-11 m2 s-1 are sufficiently supplied by diffusion only, while those with significantly lower diffusivities (?10-19 m2 s-1) require additional convective transport. The present study demonstrates the selection and contribution of chemical engineering methods in tumor model system development.

Introduction/Objective. We aimed to investigate the lifetime and periodic prevalence (during a year) and characteristics of violence against women and health status of women whose partners have been treated for alcohol dependence. Methods. A cross-sectional study was conducted among women whose male partners were alcoholdependent and admitted to hospital for the inpatient treatment. Exposure to physical and sexual violence was measured by the Conflict Tactics Scale (CTS-2). Mental health status was measured by Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI), suicidal risk (using Mini International Neuropsychiatric Interview or MINI scale), and alcohol consumption (Alcohol Use Disorders Identification Test). The data were analyzed by descriptive and inferential statistical methods. We also constructed two logistic regression models to study associations between violence and socioeconomic status, and violence and health-related variables. Results. The lifetime prevalence of physical violence committed by alcohol-dependent partners against women was 65.4%, while the periodic prevalence (during 12 months prior to the study) was 46.2% for physical, 20.2% for sexual, and 18% for both types of violence. No women were in risk of harmful alcohol consumption. Violence was more frequent against women not living in urban areas [odds ratio (OR) 2.53, 95% confidence interval (CI) 1.08?5.94, in the univariate model], and among women with moderate/ severe depression (OR 12.34, 95% CI 2.26?67.33, in the multivariate model). Conclusion. Alcohol-dependent men are very often violent toward their spouses, and inpatient treatment presents an opportunity to work with them on raising awareness on the unacceptability of violence against women.

The online learning process tends to make students' responses less active. Therefore it requires learning media that can play an active role in explaining the material, such as audiovisuals. The purpose of this study was to produce valid demonstration-based audio-visual learning media on the topic of temperature, heat, and its displacement in the fifth grade. The model used is the 4D model, which consists of defining, designing, developing, and disseminating. The subject of the trial was conducted on two material experts, two media experts, and two practitioners. The data collected are qualitative data and quantitative data. Data collection was carried out using a questionnaire method. Data were analyzed using the mean formula to determine the average media validity score. The average validity score of demonstration-based audiovisual learning media in terms of material experts is 3.92, with very good qualifications. In terms of media experts of 3.80 with very good qualifications. In terms of practitioners, it is 3.87 with very good qualifications. It shows that the demonstration-based audio-visual learning media on temperature, heat, and its displacement in fifth grade are deemed appropriate for use in the learning process.

The obstacle faced in the learning process so far is the low interest in student learning. Many factors affect interest in learning, one of which is the lack of variety of teaching materials or learning media used by teachers in schools. The use of augmented reality (AR) in education is an important topic of research although its use is still in its infancy. The purpose of this research is to develop learning media, AR-based e-magazine to increase students' interest in learning high school students, on the material of the digestive system. The development of the e-magazine is carried out using the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The parameters in this study are the quality of the e-magazine and interest in learning. Testing interest in learning is done using an interest questionnaire given to students for the control class consisting of 36 students and the experimental class consisting of 36 students. The results of the development of AR-based e-magazines are relatively good. This can be seen from the validation results with a very valid category. Based on the didactic aspect, a score of 3.82 was obtained in the very valid category, the constructive aspect was 3.85 in the very valid category and the technical aspect was 3.78 in the very valid category. The results showed that the use of AR-based e-magazines increased interest in learning. Interest in learning obtained a score of 0.342 in the high category. Thus, it can be concluded that the use of AR-based e-magazines as digital learning media can be used in the learning process.

The availability of facilities has not been able to optimize the implementation of learning. This has resulted in some students not being able to take online lessons properly; about 29.4% of students have never taken online lessons so that students miss lessons that are carried out according to schedule. This study aims to develop a website-based Learning Management System to facilitate learning during the covid-19 pandemic. This research is included in research and development (R&D) by adopting the Alessi & Trollip development model. The subjects of this study were, among others, two media experts, two material experts, and two subject teachers in junior high schools. The data collection technique used a test based on the product developed for each research subject using the appropriate instrument. The results of the questionnaire will be analyzed descriptively using the proportion to choose the LMS product. The results of the research data that the assessment above is 88.88% of media experts, the amount of material obtained is 91.22%, and prospective users consisting of students and teachers are 91.88%, which means that the acquisition of media and subject matter to be used is 81%, which are included in the very decent or excellent category so that there is no need for revision or improvement. Thus the learning application, namely the learning management system (LMS), can be used as a tool to support the learning process during online learning activities.
Regulating terrorist content on tech platforms: A proposed framework based on social regulation
Authors:   , Watkin Amy-Louise
Published: September 2021

Scholars have been arguing for years that responses to terrorist content on tech platforms have, to-date, been inadequate. Past responses have been reactive and fragmented with tech platforms self-regulating. Over the last few years, many governments began to decide that the self-regulatory approach was not working. As a result, a number of regulatory frameworks have been proposed and/or implemented. However, they have been highly criticised. The purpose of this thesis is to propose a new regulatory framework to counter terrorist content on tech platforms and overcome many of these criticisms. Scholars have argued that it is vital that future regulation be informed by past experience and supported by evidence from prior research. Therefore, a number of steps were taken. First, this thesis examines a review of literature into what platforms are exploited by terrorist organisations. Next, a content analysis was undertaken on blogposts that tech platforms publish in order to investigate the efforts that tech platforms report making to counter terrorist content on their services and the challenges that they face. Third, a sample of existing or currently proposed regulatory frameworks were examined in order to learn what was done well and what gaps, limitations and challenges exist that require addressing in future regulation. Finally, social regulation theory was identified as applicable in this regulatory context. Social regulation strategies were examined in three other regulatory contexts in order to examine whether they could be used in this regulatory context. The findings from the above analyses were used to inform a new regulatory framework that is proposed in this thesis. In addition to proposing a new regulatory framework, this thesis also identified three compliance issues that tech platforms may face. These compliance issues are addressed alongside the proposal of the framework. Overall, it is argued that previous regulatory attempts failed to consider the diverse array of challenges that are faced by different platforms when countering terrorist content. The regulatory framework proposed in this thesis researched these challenges and identified strategies from a social regulation approach, learning lessons from how they were applied elsewhere to overcome some of the key criticisms and limitations of existing regulatory practice.

The analysis of the concept of Open-Science Space is carried out. The existence of ways to achieve reproducibility and traceability of research results performed by a group of worldwide situated Cyber-physical system operators/supervisors is shown. Ways to ensure the efficient operation of Cyber-physical systems as complex technological nondemountable objects with high requirements for metrological characteristics have been studied. To develop the scattered cyberphysical systems, the portable stable-in-time code-controlled measures of physical quantities have been studied. They have to be metrologically confirmed in the laboratory before the delivery to the site of the measuring subsystem for its calibration.
