Climate Change Implications for Optimal Sizing of Residential Rooftop Solar Photovoltaic Systems in Qatar
Authors: Khan Muhammad Imran , Al Huneidi Dana I. , Asfand Faisal , Al-Ghamdi Sami G.
Published: December 2023

Climate change poses critical challenges for Qatar’s energy-intensive residential building sector. This study evaluates the impact of projected climate warming on optimizing rooftop solar photovoltaics (PV) for villas. An integrated modelling approach is employed, combining building energy simulation, PV system optimization, and performance assessment under varying climate scenarios. A typical Qatari villa is modelled in DesignBuilder and simulated under the baseline (2002) conditions and the projected years 2016, 2050, and 2100, reflecting incremental warming. Results show the villa’s annual electricity consumption will grow 22% by 2100, with summer peaks escalating to 26% driven by surging cooling demands. Techno-economic optimization in HOMER Pro (version 3.10) verifies a grid-connected rooftop PV system as optimal in all years, with capacity expanding from 7.4 kW to 8.2 kW between 2002 and 2100 to meet rising air conditioning loads. However, as temperatures increase, PV’s energy contribution declines slightly from 18% to 16% due to climate change degrading solar yields. Nonetheless, the modelled PV system maintains strong financial viability, achieving 5–8 years of paybacks across scenarios. This analysis provides empirical evidence of distributed PV’s effectiveness for Qatar’s households amidst escalating cooling consumption. However, maintaining solar mitigation potential requires evolving PV sizing methodologies and incentives to account for declining panel productivity at the country’s peak temperatures exceeding 50 °C. Overall, this study’s integrated framework evaluates residential solar PV systems’ capabilities and appropriate policy evolution under projected climate impacts for the first time in Qatar. The modelling approach and conclusions can inform building codes and pro-solar policies to accelerate adoption for emissions reduction. With villas representing over 100,000 units in Qatar, widespread rooftop PV integration can meaningfully contribute to national sustainability targets if implementation barriers are addressed considering climate change effects.

Authors: Wang Yingying , Han Dong , Ma Xiaofeng
Published: December 2023

Water transportation has always occupied a large proportion of China’s transportation and has become the key to China’s economic development. Water transportation is called “green transportation” in the industry due to the advantages of low transportation cost, high safety factor, and large capacity. However, water transportation has caused a great impact on the ecological environment of the waters for a long time, and solving the problem of sewage pollution from ships has also become an unavoidable problem. To control pollution from ships, it is essential to analyze the characteristics of ship domestic sewage discharge. In this study, a ship domestic sewage discharge complex network (SDCN) is established based on the ship voyage data to analyze the discharge characteristics in the Yangtze River. According to the topological analysis, the SDCN is a small-world network with the power-law degree distribution and superliner betweenness-degree correlation as distinguishing characteristics. The top five MDs with the highest in-vertex strength are Chaotianmen MD (S = 165,129,561), Tongling MD (S = 66,426,616), Maanshan MD (S = 62,087,158), Baqu MD (S = 59,964,550), and Shashi MD (S = 55,569,399), which indicates that these MDs receive a large amount of sewage. And the volume of domestic sewage between Chaotianmen MD and Baqu MD is the largest. The results can help us understand the discharge characteristics of ship domestic sewage and how they can be targeted to develop control measures for the countermeasures of “zero discharge” for inland ships.

Published: December 2023

O leite é uma importante fonte de proteínas com alta qualidade, vitaminas, gordura, carboidratos e sais minerais (NOGUEIRA et al., 2009). O Brasil se enquadra entre os 5 maiores produtores de leite do mundo. De acordo com o IBGE, no ano de 2014, nos nove primeiros meses, a produção aumentou 7% em relação ao mesmo período de 2013. A mastite é uma inflamação da glândula mamária, que caracteriza-se como sendo uma doença infecciosa mais comum que afeta o rebanho leiteiro. Ela provoca extensas perdas econômicas devido a diminuição da produção de leite, a produção de leite com baixa qualidade, custos elevados com tratamento e abates prematuros de vacas com mastite crônica. Desta forma, o objetivo deste trabalho foi demonstrar os procedimentos de prevenção da mastite bovina, tais como pré-dipping e pós-dipping e sua importância ao agronegócio. Portanto a mastite é o principal problema na pecuária leiteira, pois causa graves prejuízos ao produtor com descarte do leite, custos com o tratamento, perda do teto ou até a glândula mamária e em casos mais graves podendo levar a morte do animal. Cabe aos profissionais do agronegócio a concientização dos proprietários e as corretas informações e procedimentos para o controle e prevenção da mastite bovina.
Antecedents of crowdsourcing in science: scale development and initial testing
Authors: Lenart-Gansiniec Regina
Published: December 2023

Crowdsourcing in science has become a growing field of research interest. Although the importance of crowdsourcing in science along with its barriers and requirements have been well recognized in the literature, many questions remain open. One of them refers to factors that determine the intention of academics to use crowdsourcing in science. Besides, previous research is held back by the lack of a rigorous measuring instrument. The aim of the article is to identify the antecedents of crowdsourcing in science, as well as the construction and initial testing of the measuring scale. Identifying the antecedents of crowdsourcing in science followed a combined approach, i.e., systematic literature review and nine focus group discussions were used. The process of developing the scale and its initial testing includes a pilot study conducted among 66 researchers. The final scale consists of 38 items covering the five antecedents of crowdsourcing in science.

Published: December 2023

This research is a part of the Erasmus+ internationally funded InDo research project, involving a consortium led by an Italian higher education institution. An objective of the project is to include desk and field research on the topics of Understanding by Design and Differentiated Instruction, which led to this article having been produced, for knowledge transfer purposes. To carry out this research study, the Boolean operators "Understanding by design"; "Differentiated instruction"; "Higher education" and, "Cross-disciplinary material" applied to the title, abstract, and keywords in the Scopus database were used. Using all operators simultaneously returned no results. Only the Boolean operators "Differentiated instruction" AND "Higher education" and the operator "Cross-disciplinary material" alone brought results. 24 articles were found on Differentiated instruction and Higher education. This group of articles was previously analyzed in a Bibliometric way, using the "Bibliometrix" package from the free software R Studio. Regarding the searches for the term "Cross-disciplinary material", the Scopus database returned only 1 result, which was combined with the 24 articles previously identified, totaling a total of 25 articles related to the two themes. Given the difficulty of access - articles, books, and book chapters with restricted access - 6 investigations were excluded, leaving 19 potentially relevant articles, which were read in their entirety. From the analysis of the 19 articles selected for full reading, 1 investigation was excluded for not fitting the parameters of this research, resulting in a total of 18 articles that were analyzed using a meta-synthesis. After the analysis performed, it can be seen that the main theory used has been differentiated instruction coupled with issues such as standardized assessments for the identification of learning styles, personalized feedback instruments, online applications, the perception of self-efficacy, as well as concern for the development of analytical models for differentiated instruction. Less expressively, other theories that emerge from the analysis performed, are the flipped classroom, Universal Learning Design, a diagnostic assessment and interdisciplinary education.
Business research methods: A perspective of street traders in the informal economy
Authors: Mabasa Dumisani Godfrey
Published: December 2023

Many people, despites being educated or not, struggle to find decent jobs in the formal economy. Some end-up working in the informal economy as self-employed/own-account workers. Informal economy is the largest employer with more potentials, employing approximately 61 percent of the global labour force. Despite different forms of occupations, street trading is the most visible occupation in the informal economy. There is a research gap between formal and informal economy, with most research done in the formal economy. It is recommended that micro-level individuals must be included in research to broaden knowledge. The informal economic activities are not reported in government statistics. It is odd because the informal economy is the largest global employer and street trading is found in both developed and developing economies. Informal economic activities are however associated with lack of growth and social security, money laundering, and financing of terrorist activities. The study was conducted to determine work engagement of street traders using the Utrecht Work Engagement Scale (UWES). The UWES is validated and used for quantitative studies in the formal economy. The instrument was pretested and piloted for quality appraisal purposes for validation and use in the informal economy. The general lack of credible records of street trading activities, makes it difficult for researchers to conduct studies using different methodologies in the informal economy. The convenience sampling strategy, a nonprobability sampling startegy, was used in choosing participants, and  was most valid for solving the problem of the study, choosing participants accidentally on availability. Most quantitative studies involving street traders are restricted to using nonprobabiliity sampling, which is a concern. The high birth and/or mortality rate of street trading businesses make the database inconsistent to use as some do not report when exiting or entering. The lack of credible records/database of street trading activities, and over reliance on nonprobability sampling strategy, restrict the holistic generation of knowledge. The street traders’ activities must be registered to develop from knowledge generated through research.
Quantitative Analyses of the Role of Relational Capital on Absorptive Capacity in Knowledge-intensive SME's
Authors: Tonial Graciele , Matos Florinda , Cassol Alessandra , Marietto Márcio Luiz , Werlang Nathalia Berger
Published: December 2023

The research aimed to measure the relational capital influence (RC) on absorption capacity in knowledge-intensive companies. The direct relationship between the different components of relational capital and absorption capacity was analysed through a model of structural equations of partial least squares (PLS-SEM), tested in SmartPLS. This method was chosen for the following reasons: the use of SEM-PLS allows testing causal paths between second-order latent variables, and in addition to offering extensive and flexible causal modelling resources, the technique is recommended for more complex models, with constructs composed of a greater number of variables and with a smaller number of data, as observed in this research. The method is also justified because this research is based on a composite measurement model with a reflective design approach, which means there are correlations between indicators and dimensions. The SmartPLS 3.0 Software was used to carry out the global model evaluation and measurement and structural model evaluation steps. These analyses were conducted in a sample of 174 small and medium-sized technology enterprises (SMEs) that are part of different innovation networks in Brazil. This study highlights that the development of relational capital is supported by collaborative relations of cooperation, trust, communication, and resources invested by enterprises established in different networks. The proposed statistical model allowed proving the relationship factors that help strengthen the relations between the network actors that facilitate the transfer of knowledge. This relationship still needs to be investigated, especially for small and medium-sized knowledge-intensive companies in emerging countries like Brazil. The research conclusion supported the research hypothesis and proved that relational capital is an independent variable that directly and positively influences the absorption capacity process. This study, quantitatively combining the external perspective of relational capital and the internal organisational dimension of absorption capacity, provides valuable information about using quantitative methodologies to explore intangible organisational resources to promote innovation.
Reaping Research Skills from the Rigorous Application of Design Thinking
Authors: Turpin Marita , Weilbach Lizette , Kruger Sean
Published: December 2023

This paper investigates the relationship between design thinking and the research process, and argues that design thinking can foster the development of research skills. The paper reports on a case where first year Information Systems students apply Design Thinking (DT) in an Internet of Things (IoT) practical assignment. The Hasso Plattner Institute (HPI)’s design thinking process is applied, which entails five phases: empathise, define, ideate, prototype and test. In the Empathise phase, students must collect and analyse data in order to understand user needs. This enables them to arrive at an evidence-based problem definition in the define phase. Later, during the test phase, data is again collected and documented on the user’s experience of the prototype. User feedback is then compared with the documented user needs and adjustments are made to address the possible gap. While design thinking is not a conventional research methodology, its use in this manner adds rigour and a scientific base for devising creative solutions. In the group assignment, students were required to document their implementation of the five DT phases by means of a group blog, which was used to assess their projects. While assessing the blogs, the lecturers noted that the students who were more thorough and meticulous in documenting and analysing the user need data, were able to arrive at designs that more appropriately responded to the user’s needs. Furthermore, students who provided quotes and/or transcripts of their user interviews, followed by similarly documented feedback during the demonstration and testing of their prototypes, not only convinced that they addressed the real user problem, but the rigour they applied facilitated more innovative designs. This was an interesting finding, because the innovation itself is usually associated with the creative phases (ideate and prototype) rather than the empathise and test phases. This paper argues that when applying DT in a rigorous manner, students are enabled not only to produce better designs, but they also gain valuable research skills for their future benefit.
Structured Literature Reviews for Business Professional Doctorates:
Authors: Ganga Rafaela , Wilson Hannah , Tucker Matthew
Published: December 2023

The first significant piece of writing a Professional Doctorate must undertake is reviewing the literature within their elected field, allowing them to synthesise relevant theories and concepts underpinning their research (Pickering & Byrne, 2014). The task involves searching, assessing, screening and synthesis a significant literature volume. Often this task is perceived as daunting, potentially leading to periods of demotivation, where students feel stuck, particularly in Professional Doctorates (Wisker, 2015). A basic principle of Professional Doctorates is that candidates contend with the tensions of professional practice and academic scholarship, making sense of the intricacies of crossing intellectual boundaries (Wasserman & Kram, 2009). However, many professional doctorate students have been absent from higher education learning for a long period of time (Allen et al., 2002), to which the literature review process is crucial for doctoral students as it is their opportunity to cross ‘conceptual thresholds’, which is crucial for gaining new insights into a topic (Wisker, 2015). For professional doctorate students, this process is interconnected with their deep understanding of their professional practice, which drives knowledge production (Costley, 2013). This paper discusses the characteristics of using structured literature reviews as a pedagogical strategy in a credit-bearing taught module for professional business doctorates. It aims to assess the value of structured literature reviews to improve learning outcomes, doctoral completions and publishing opportunities. The analysis is drawn on a critical case study of the Literature Review module within the Doctorate in Business Administration (DBA) programme at Liverpool John Moore's University. The DBA is used as a critical case study for this research, as it represents the most mature and developed professional doctorate in the University. It reviews the module's internal structure addressing the coherent contents-aims/content-learning outcomes connection and learning techniques (Leger & Sirichand, 2015), the value of research-informed teaching (Joseph-Richard, Almpanis, Wu, & Jamil, 2021), and an exploratory review of students' satisfaction levels (Pickering & Byrne, 2014).
BRICS TENDENCIES TOWARDS REDEFINING THE GLOBAL ECONOMIC ORDER
Authors: Stojković Radomir , Milosavljević Slađan
Published: December 2023

The paper analyzes the tendencies of BRICS (Brazil, Russia, India, China, South Africa) as an informal block for the creation of a new global economic and political reality. Former superpowers and economies with the most pronounced growth trends are today gathered around a common idea - the creation of an alternative global order. Propagating their vision of the modern world, the BRICS member states seek to change the current constellation of forces at the global level, shift the center of world power from the Euro-Atlantic region and create functional multilateralism. Using the idea and concept of the New Silk Road, China is strengthening its influence in an area where it was not represented during the first decade of the 21st century. Russia is building a new global position based on its energy potential and military cooperation with non-European countries Brazil, India and the Republic of South Africa use instruments of economic diplomacy to further strengthen competitive activities. Brazil is focused on the growth of the trade exchange of agricultural products, above all, fruit. India is repositioning itself globally on the basis of industrial production in the field of information and communication technologies. The Republic of South Africa, as the most developed country in Africa, finds the basis for a new role on the international stage in natural resources and a developed mining sector. The individual influence that the states of this forum have in the global framework is strengthened by joint and coordinated action within the most important global institutions. Certain changes have been made in the quota system of the International Monetary Fund, the issue of the election of leading individuals of the World Bank Group and the World Trade Organization is increasingly topical, as well as the reform of the United Nations Organization, all as a result of the influence of the BRICS countries in the aforementioned institutions.
THE IMPACT OF CLUSTERING ON COMPETITIVENESS AND BUSINESS PERFORMANCE OF SMEs: EVIDENCE FROM THE SERBIAN AUTOMOTIVE INDUSTRY
Authors: Beraha Isidora , Đuričin Sonja , Lazarević Marija
Published: December 2023

Clusters are widely regarded by scientific researchers and policymakers as effective tools for addressing the size constraints faced by SMEs. The increased involvement of local SME suppliers in supply chain restructuring has led to the extensive adoption of clusters in the automotive industry. Despite a wealth of literature supporting the economic advantages of clustering, the absence of quantitative evidence has constrained policy support for cluster development in numerous developing countries. This research aims to empirically compare the performance of clustered and non-clustered SMEs within the same industry. The primary objective is to quantify the impact of the Serbian Automotive Cluster on the competitiveness and business performance of Serbian automotive SMEs. Utilizing Stochastic Frontier Analysis and statistic tests, the methodology examines a balanced panel of 29 SMEs in Serbia’s automotive industry spanning from 2016 to 2018. The impact of clustering is analysed in terms of efficiency and effectiveness, crucial dimensions of business success. Total revenue is used to measure efficiency, reflecting an integral competitive indicator. Effectiveness is assessed using profitability indicators such as profit margin, asset turnover ratio, and return on assets. The research reveals that clustered SMEs in the automotive industry exhibit higher efficiency (competitiveness) and effectiveness (profitability) compared to non-clustered SMEs. The proposed methodology holds significance for evidence-based policymaking, providing empirical support for cluster policy. The paper introduces a novel quantitative assessment methodology for gauging the impact of clusters on SME members’ competitiveness and business performance. The unique approach adds value to the paper, as similar methodologies have not been previously applied in assessing the impact of clustering on efficiency and effectiveness, fundamental dimensions of business success. The suggested methodology holds importance due to its potential applicability in evaluating how clusters influence the performance and competitiveness of SMEs across diverse industry sectors in developing nations. Acknowledging the limitations of our research, notably the small sample size that focused solely on SMEs with publicly available financial statements, excluding numerous enterprises from the analysis, we underscore the significance of clustering in enhancing the business performance of SMEs in the automotive industry. This emphasizes the need for additional research in quantitatively measuring the impact of clusters, paving the way for further exploration in this direction.
A THEMATIC AND STRUCTURAL ANALYSIS OF TEKHAYYULĀT: THE PROMINENT PERSIAN POETRY COLLECTION BY NAIM FRASHERI
Authors: Safari Saeed , Malja Imami Naijle
Published: December 2023

The spread of Islam in the Balkans under Ottoman rule along with the emergence of Sufi sects, including the Bektashi order, paved the way for the expansion of Persian literature as a source of Sufi literature in this region and especially in Albania. Over the centuries, the Persian language and literature have maintained their presence and function in the Balkans, and several Sufi figures and intellectuals have chosen Persian as the medium for the expression of their literary creations. Among them, The most well-known Albanian who wrote Persian poetry in the late 19th century is undoubtedly Naim Frasheri (1846-1900). He published his collections of Persian poems, entitled “Tekhayyulāt” in 1885 in Istanbul. In this paper, after an overview of the spread and development of the Persian language and literature in the Balkans and in Albania, Naim’s poems in “Tekhayyulāt” are presented and analysed. The study is grounded on the theory of formalism in literature and aims to apply structural analysis to Naim’s Persian poems. To this end, employing a qualitative approach as the research methodology, two types of analyses are conducted, thematic analysis which reviews the content and the themes of his poems, and then structural analysis which is based on Leech’s theory of linguistic deviation (1969), focuses on the application of three types of linguistic deviations, namely phonological, lexical and grammatical, to enable a structural analysis of the poems. The results of the analysis show that Naim’s Persian poems have limited ranges of themes, and the main theme in his poems is about ‘nature’ while the structural analysis of linguistic deviations in his poems indicates his mastery of the Persian language to express his thoughts in poetic form.

Authors: Obradović Maja , Mizdraković Vule , Obradović Ana , McIntyre Jelena
Published: December 2023

The omnipresence of social media has significantly influenced and shaped contemporary businesses. Online presence has become one of the main prerequisites for survival and success of companies in a dynamic and competitive environment. Digital presence and image of a company in online marketplace has become much more important than ever before. The aforementioned was especially pronounced during the COVID-19 pandemic when the period was marked by social distancing of people in their physical environment. Interestingly, social distancing ultimately led to the increased use of the Internet in conducting everyday personal and professional activities. The purpose of this paper is twofold. First purpose is to investigate social media presence of audit firms in Serbia. The second purpose is to analyze correlation between the financial performance of audit firms and their social media metrics during the COVID-19 pandemic. The contribution of this paper is to investigate to what extent Serbian audit firms use social networks for promoting their consulting and auditing services, with the purpose of attracting new clients. Results show that audit firms that belong to international networks are significantly more present on social media, while approximately 80% of domestic audit firms in Serbia are not present on the observed social media platforms: Facebook, Instagram, and LinkedIn. Regarding profitability, results show that there is a high statistically significant correlation between EBITDA and observed metrics of Linkedin and Instagram social networks.

Published: December 2023

Magnets are a part of students’ daily experience, whether within technical devices, souvenirs, toys or included in various school experiments. The aim of this research was to gain insight into the way primary students understand magnetism and to estimate the effect of teaching to the development of concepts about magnetism. For the purpose of this research, a diagnostic knowledge test was designed which includes teaching content about the concept of magnets, their properties, interaction and application. A total of 160 of second, third and fourth grade students attending elementary schools „Siniša Glavašević“ and „Nikola Andrić“ from Vukovar and „Bijelo Brdo“ from Bijelo Brdo, Republic of Croatia, were included in the study. The results showed that there were no statistically significant differences in knowledge test scores among girls and boys. The knowledge test achievements according to age (second, third and fourth grade) were statistically significant between second and third grade, as well as second and fourth. The difference in test scores between third and fourth grade students was observed, but it was not statistically significant. The analysis of students’ responses according to each test question confirmed the absence of differences according to gender but significant differences according to age, as well as the persistence of some typical misconceptions. The overall level of knowledge test achievement was rather low throughout the sample, indicating that primary students lack sufficient knowledge and that the majority of students fail to completely and accurately answer the questions about magnetic phenomena. Based on the results of this study it could be concluded that the process of developing concepts about magnetism within the course Nature and Society from the second to the fourth grade is insufficiently effective. We recommend that the contents about magnetism should be studied from the very beginning of primary school education. Furthermore, it is necessary to apply innovative teaching methods, strategies and models, while connecting these contents with students’ everyday experiences.

Diversas práticas educacionais utilizam instrumentos didáticos criativos para capacitar pessoas para analisar e interpretar dados.A literacia em visualização de dados é uma demanda relevante diante da quantidade de informações disponíveis na contemporaneidade.Este artigo foca no desenvolvimento de um jogo de cartas de visualização de dados com o objetivo de criar nos participantes o interesse em conhecer, analisar e argumentar sobre diferentes tipos de visualizações e aplicá-las a um conjunto de dados. Apresentamos o processo de criação do jogo e como foi avaliada a experiência de sua prática. Nosso processo metodológico integrou o design thinking e as abordagens construcionistas de aprendizagem. Ao apresentar os pontos em comum dos dois processos, destacamos o caráter educativo da prática projetual.
Síndrome de Cushing: una observación en la infancia
Authors:   , Ponce De León Héctor Hernán
Published: December 2023

El llamado Síndrome de Cushing, es una entidad clínica que ha suscitado, en lo que a interpretación de su etiopatogenia concierne, las más encontradas opiniones de sus investigadores en estos últimos años. No obstante su sintomatologla era bien reconocida desde muy antiguo a tal punto que parece que ya en época de Hipócrates ocupó la atención de algunos observado res, apareciendo posteriormente con el correr del tiempo, ciertas descripciones de pacientes cuyas alteraciones somáticas y sexuales, corresponden verosímilmente a la enfermedad que nos ocupa, aunque se les atribuyó en su oportunidad orígenes de lo más dispares. Es recién la medicina moderna, con sus grandes progresos en el campo de la endocrinología que la relaciona con su verdadera causa: alteraciones del eje hipofiso-adrenal. Pero antes de los trabajos de Cushing, y desde comienzos de este siglo, por el hecho de coincidir muchos de sus síntomas con los observados en casos de tumor suprarrenal, su verdadera identificación quedaba a oscuras y se le englobaba dentro del nombre genérico de Síndrome Adrenogenital.
Study of The Potential of Palm Oil Empty Core Fiber As Composite Materials for Ship Hull
Authors: Harefa Daniel Kurniawan
Published: December 2023

Palm oil is the largest commodity in Indonesia. Pprocessing of oil palm, leaving 20% to 23% empty palm fruit bunches (EFB). Oil palm empty fruit bunches (EFB) is a collection of fiber left behind after separating the fruit from fresh fruit bunches that have been sterilized. Some researchers use natural fibers as an alternative for making composites. This study aims 1. To determine the tensile strength of the alternative material of palm empty fruit bunch fiber. 2. To determine the buckling or bending strength of the alternative fiber material for empty palm oil bunches. The method used is the tensile and bending test method in the process of mixing the fiber material of empty palm oil bunches in the manufacture of composites. The test results obtained were compared with the BKI composite standard. The volume fraction used in this study was 30% polyester resin and 70% EFB fiber, 40% polyester resin and 60% EFB fiber and 50% polyester resin and 50% EFB fiber with NaOH alkaline treatment for 2 hours. The average tensile stress values obtained for each fraction were 27.372 MPa, 24.168 MPa and 25.875 MPa respectively. The values for the bending stress of each fraction are 144.836 Mpa, 149.059 Mpa and 164.682 Mpa respectively.
MULTILATERAL REGULATION OF DIGITALIZATION PROCESSES
Authors: BALASHOVA Valeriya
Published: December 2023

The article provides substantiation for the importance of multilateral regulation within the field of digitalization processes. The author has conducted an analysis of the current status, consequences, and shortcomings of liberalising international trade in key ICT products under the WTO’s Information Technology Agreements (ITAs). The combined economic impact of these two ITAs has been estimated at approximately three trillion dollars annually. However, it is important to acknowledge that these agreements encompass fewer than half of the WTO’s member countries. The study reveals that existing international regulation initiatives concerning the digital economy primarily operate on a voluntary basis, focusing on specific aspects of digitalization and involving only a limited number of countries. The author contends that the demand for comprehensive multilateral regulation in digitalization arises from potential global-scale issues and risks. Consequently, the following priorities for multilateral regulation in digitalization are delineated: establishing consensus on fundamental definitions of digital processes, terms of data access, the concept of digital data as a global public good, forms of data management, rights and principles pertaining to digital data, data standardization, and international cooperation in platform management. In conclusion, the author emphasizes the need for an integrated and balanced approach to support the inclusive and sustainable global economic development, as well as the potential for creating an international entity tasked with overseeing various aspects of digitalization.
