Authors: Farhana Nova Dwi , Ariyanti Fajar
Published: June 2024

HIV/AIDS masih menjadi infeksi yang berbahaya karena infeksi oportunistis yang ditimbulkan. Pamekasan merupakan Kabupaten dengan prevalensi HIV/AIDS tertinggi kedua di Pulau Madura pada tahun 2014. Beberapa kasus menunjukkan adanya ODHA usia produktif yang hidup dengan memiliki pasangan negatif (pasangan serodiskordan). Perilaku pencegahan penularan HIV harus dilakukan oleh pasangan serodiskordan karena berpotensi meningkatkan insiden HIV/AIDS. Tujuan penelitian ini ialah untuk mengetahui bagaimana perilaku pencegahan penularan HIV oleh pasangan serodiskordan di Kabupaten Pamekasan tahun 2018. Penelitian ini adalah penelitian kualitatif pendekatan fenomenologi. Data dikumpulkan dengan wawancara mendalam. Informan utama adalah 4 pasangan serodiskordan yang terdiri dari 4 ODHA dan 3 pasangan negatifnya. Informan kunci adalah konselor VCT. Hasil penelitian menunjukkan sebagian besar pasangan serodiskordan memiliki persepsi ancaman, persepsi manfaat, isyarat untuk bertindak dan efikasi diri yang baik dan semua pasangan dengan status HIV positif memiliki hambatan. Sebagian besar perilaku pasangan serodiskordan tergolong baik namun juga ditemukan pasangan yang berperilaku kurang baik dalam mencegah penularan HIV, yaitu pada pasangan yang menemukan banyak hambatan. Sebagian besar memiliki pengetahuan yang kurang terkait HIV/AIDS terlebih pada pasangan dengan status HIV negatif. Konseling berpasangan yang dijadwalkan secara berkala disarankan agar pasangan serodiskordan memahami sepenuhnya fungsi dan manfaat dari upaya pencegahan yang dilakukan, selain itu konselor juga diharapkan memberikan konseling terkait masalah psikososial yang dihadapi pasangan serodiskordan serta senantiasa mengingatkan ODHA terkait efek samping yang diberikan.

Managing water-related vulnerability and resilience of urban communities in the Pearl River Delta
Authors: Yang Liang Emlyn
Published: June 2024

Globally, growing concern about disaster risks necessitates the implementation of actions that combine vulnerability reduction and resilience building. This paper applies the concept of vulnerability and resilience to urban communities in the Pearl River Delta along the Southern Chinese coast that are facing climate-related water hazards. The study integrates a reanalysis dataset and model projections with literature results on long-term climate changes, which support a comprehensive risk analysis of both floods and water shortages in the Pearl River Delta within the regional climate change context. A flood vulnerability assessment indicates that pre-existing vulnerabilities are exacerbated after flood impacts. The main factors influencing the vulnerability of coastal communities are related to economics, institutional capacity, and the accessibility of knowledge for local community-based organizations. Many communities have been able to reinforce their resilience through local initiatives, including investing in infrastructures, sharing responsibilities, diversifying engagements, network recoveries, and water security nets for the most vulnerable ones. To ensure that the delta’s communities are well adapted to climate and water threats, it is clear that investing in building community resilience and safety nets is important. This paper further highlights that community efforts, government supports, and external assists should be better organized to reinforce the abilities of the people at the local level.
Critical evaluation of the implementation of the concept of environmental security
Authors: Hardt Judith Nora
Published: June 2024

This paper analyzes the theoretical and empirical conceptual approaches to the link between environment and security in order to test their ability to function as guiding concepts in the multiple and complex challenges posed by the Anthropocene. For this purpose, the Critical Environmental Security Studies (CESS) are proposed and further developed in order to bridge the theory-practice gap and inform the literature on the conceptual approach carried out by the Environment and Security Initiative (ENVSEC).The empirical research that attempts to pinpoint and evaluate the dominant conceptual use of environmental security in reference to geopolitics, status quo maintenance, and normative change relies on document analyses of the period from 2001 to 2014 and semi-structured interviews with decision-makers of ENVSEC.

Published: June 2024

La base de todo sistema productivo es la reproducción; por lo que el desarrollo de las hembras de reemplazo debe ser una prioridad para el ganadero, de estas depende parte del éxito reproductivo del hato. Este estudio evaluó el desarrollo corporal y aspectos reproductivos de novillas brahman y simbrah F1, las cuales se mantuvieron bajo las mismas condiciones ambientales, de manejo y de alimentación. Se utilizaron 60 hembras (30 brahman y 30 simbrah F1). Durante el experimento, los animales se pesaron de manera mensual. Desde los 12 meses de edad hasta los 19 meses, se realizaron evaluaciones con ultrasonido transrectal para evaluar el desarrollo del tracto reproductivo. Las variables evaluadas fueron: peso corporal (PC), condición corporal (CC), diámetro del cérvix (DC), diámetro del cuerno uterino derecho (DCD), diámetro ovario izquierdo (DOI), diámetro ovario derecho (DOD), cantidad y tamaño de folículos [TF1 (≥ 10 mm), TF2 (6-9 mm), TF3 (≤ 5 mm)], diámetro del cuerpo lúteo neto (DCLN) y ciclicidad. Se obtuvo mayor peso corporal para los animales simbrah F1 (p=0.0026); aproximadamente 50 kg más en promedio con respecto a los brahman. La CC fue aumentando conforme incrementó el peso y edad de los animales [(p=0.021) y (p=0.0485), respectivamente]. Con relación a aspectos reproductivos, se obtuvo un incremento para todas las variables (DC, DCD, DOD, DOI, TF1, TF2, TF3 y DCLN) en ambos grupos raciales de acuerdo con la edad. Además, en el grupo racial simbrah F1, el DC (p=0.028), DCD (p=0.0037) y DCLN (p=0.0303) fueron mayores que en Brahman; mientras que para DOD, DOI, TF1, TF2 y TF3 el comportamiento entre los grupos raciales fue similar (p>0.05). Este estudio evidenció el mejor desempeño, a nivel de ganancia de peso y desarrollo de estructuras reproductivas, de las novillas del grupo racial simbrah F1 comparado con las novillas brahman puras.

Published: June 2024

El objetivo del presente estudio fue evaluar parámetros de crecimiento y eficiencia en la fase inicial de desarrollo de la tilapia azul (Oreochromis aureus) al consumir alimentos comerciales con diferentes contenidos nutricionales y bajo distintas tasas de alimentación diarias (TAD). La investigación se realizó durante 56 días en la Estación Experimental Alfredo Volio Mata (EEAVM) de la Universidad de Costa Rica. Se utilizaron 96 alevines sometidos previamente a un proceso de reversión hormonal con un peso inicial de 5 ± 1,5 g. Después de una aclimatación de 10 días, los peces se dividieron, según su peso, en grupos de seis individuos y en doce peceras. Se utilizaron alimentos comerciales A y B con proteína cruda (PC) al 40% y 36%, respectivamente; ofrecidos a una TAD inicial de 5% y 7%. Los tratamientos PC 40/7, PC 36/7, PC 40/5 y PC 36/5 se asignaron aleatoriamente, resultando en cuatro repeticiones cada uno. Se monitoreó diariamente el consumo de alimento y cada 15 días se anestesiaron los animales para evaluar las ganancias de peso (P), la longitud estándar (LE), el ancho total (AT), el coeficiente térmico de crecimiento (CTC), la tasa de crecimiento específico (SGR), el factor de condición K (FK), la tasa de conversión alimenticia (FCR), la tasa de eficiencia proteica (PER) y el índice viscerosomático (IVS). La energía de los alimentos fue el principal determinante en la relación PD:ED, que fue estimada en 91,04 g PD/Mcal ED para el A y de 82,66 g PD/Mcal ED para el B; ambas menores a las especificadas según su etiqueta. Se observaron diferencias significativas (p < 0.05) entre tratamientos según la TAD inicial aplicada; la de 7% resultó en mejores variables de crecimiento (P, LE, AT, SGR y CTC) y la de 5% en las de eficiencia (PER y FCR). El alimento solo afectó significativamente (p = 0.035) la LE final y la interacción TAD-alimento sobre el IVS (p = 0.016), pero no se consideraron determinantes ante el desempeño general de los animales.
Antimicrobial susceptibility of Pasteurella multocida strains isolated from different host species
Authors: Pintér Krisztina , Pollák Boglárka Dóra , Gantelet Hubert , Magyar Tibor
Published: June 2024

The spread of antibiotic resistance is one of the biggest challenges of our time, making it difficult to treat bacterial diseases. Pasteurella multocida is a widespread facultative pathogenic bacterium, which causes a wide range of diseases in both mammals and birds. In the present study, antibiotic susceptibility of 155 P. multocida strains were tested using the broth microdilution method to obtain the minimum inhibitory concentration (MIC) values for 15 antibiotics. The most effective antibiotics against pasteurellosis were ceftiofur, tetracycline, doxycycline, florfenicol and tilmicosin. Of the strains, 12 proved to be multi-drug resistant (MDR). To combat antibiotic resistance, it is important to establish a pre-treatment antibiotic susceptibility profile. A well-chosen antibiotic would not only make the treatment more successful but may also slow down the spread of resistance and the evolution of MDR strains.

Published: June 2024

Botrytis cinerea is one of the fungal pathogens with the widest host plant spectrum, causing serious yield losses and significant economic damage in vineyards from year to year. As an ubiquitous, polyphagous fungal pathogen, with both saprophytic and parasitic lifestyle. The sequential use of active substances belonging to the same chemical family to protect vineyards can lead to an increase in fungal chemical resistance, which is reflected in the enrichment of point mutations in the genomic regions coding proteins involved in the mechanism of action of different pesticides. The aim of our studies was to compare the sensitivity to different fungicides of B. cinerea populations in two wine regions with different pest management practices: the Tokaj region, where the presence of B. cinerea is necessary to produce noble rot wines, and the adjacent Eger Region, where a total protection against B. cinerea is desired. Our study is the first Hungarian report of some previously studied resistance mutations in ERG27 and SDHB protein-coding genes. We identified point mutations in ERG27 transmembrane domain that have not been previously described but may affect the emergence of resistance to certain fungicides. Our study shows that the B. cinerea population of the Northern Hungary region is consistently characterized by an increase in fenhexamid resistance.

Published: June 2024

Lead halide perovskites are notorious for water-sensitivity and low hardness. Consequently, polishing CsPbBr3 crystals to achieve high-quality surfaces is challenging. We present a breakthrough mechanical polishing methodology tailored to the specific needs of these soft, moisture-sensitive semiconductors. Three-dimensional optical surface profiles over ~ 1 mm2 areas demonstrate high-quality surfaces with root-mean-square roughness values (< 10 nm) that are unparalleled for melt-grown CsPbBr3. We additionally delve into the polished wafers’ fundamental optical constants and introduce an anti-reflection coating method, setting new standards for short-wave infrared transparency in CsPbBr3. These pivotal processing guidelines pave the way for advancing halide perovskite applications beyond academic curiosity.

Authors: Kartal Hakan , Gebeloğlu Naif , Shakir Zuher Rashid , Karataş İbrahim
Published: June 2024

A peat-perlite mixture is preferred as a growing medium for seedlings in tomato, cucumber, and pepper. However, the unavailability of suitable peat material for seedling cultivation in our country results in a dependence on foreign sources in this field.In the experiment, 13 different growing media control 2:1 ratio of peat: perlite; Grape compost; Apple compost; Tomato compost; Grape+apple+tomato compost; 2:1 ratio of grape compost: perlite; 2:1 ratio of apple compost: perlite; 2:1 ratio of tomato compost: perlite; 2:1 ratio of (grape+apple+tomato compost): perlite; 1:1:1 ratio of grape compost:peat: perlite; 1:1:1 ratio of grape compost:peat: perlite; 1: 1:1:1 ratio of apple compost:peat: perlite; 1:1:1 ratio of tomato compost:peat: perlite; 1:1:1:1 ratio of (grape+apple+tomato compost):peat: perlite) The tomato, cucumber and pepper seed germination rate, seedling height, stem thickness, number of leaves, leaf color, seedling wet and dry weight, root wet and dry weight were examined. As a result of the experiment, alternative media to peat: perlite mixture (control) attracted attention.
Systematics of Oxalis subgenus Thamnoxys section Holophyllum (Oxalidales, Oxalidaceae)
Authors: Fiaschi Pedro , Bilk Karin D. , Sartor Mariana Furlan , da Costa-Lima James L. , Lima Duane F.
Published: June 2024

Abstract— Oxalis sect. Holophyllum (Oxalidaceae) is a small group of species that is endemic to the Brazilian Atlantic Forest in the states of Rio de Janeiro, Minas Gerais, Espírito Santo, and Bahia. Species of the section can be recognized by their
unifoliolate leaves, one-seeded carpels, and the common presence of dorsiventrally flattened (and sometimes winged) peduncles and/or petioles. Circumscriptions of the currently accepted species needed to be revaluated, as the overlap in several features have blurred limits among morphologically
similar taxa. In this study we evaluate the monophyly and phylogenetic relationships among species of O. sect. Holophyllum, and provide an updated taxonomic study of the section, aiming at improving species circumscriptions and facilitating species-level identification. For this
task, we analyzed samples from herbaria and carried out fieldwork to observe the plants in loco, collect samples, and gather material for DNA extraction, amplification, and sequencing. Bayesian and maximum likelihood phylogenetic analyses were performed using sequences from three markers:
nrITS, and plastid trnL-trnF, and petA-psbJ from 13 of the 17 currently accepted species, which corroborate the monophyly of the section. Among the species of O. sect. Holophyllum, ten are newly described here at species level: O. adpressipila Fiaschi & Bilk (based
on O. kuhlmannii Lourteig var. adpressipila Lourteig), O. capixaba Fiaschi & Bilk, O. cornicarpa Fiaschi, O. inopinata Fiaschi & Bilk, O. itamarajuensis Fiaschi & Bilk (based on O. alata Mart. ex Zucc. var. hirta Lourteig),
O. leonii Fiaschi & Bilk, O. occulta Fiaschi & Bilk, O. retrorsa Fiaschi & Bilk, O. sciophila Fiaschi & Bilk, and O. septentrionalis Fiaschi & Bilk. Lectotypes are chosen for nine names, and an epitype for O. impatiens Vell. An
identification key to all species is provided, as well as descriptions, illustrations, geographic distribution maps, and preliminary conservation statuses following IUCN guidelines. Keywords—Atlantic Forest, conservation, endemism, new species, taxonomy.
Taxonomic Circumscription of Columnea lophophora (Gesneriaceae) Supports the Recognition of Two New Species from the Andes of Ecuador and Peru
Authors: Clark John L. , Smith James F.
Published: June 2024

Abstract— Two new species of Columnea are described from the Andes of Ecuador and Peru. Columnea machupicchuensis J.L.Clark & J.F.Sm. is a subwoody subshrub with tubular purple flowers and is endemic to the forests surrounding the Machu Picchu Inca
citadel in the Eastern Cordillera of southern Peru. Columnea flavostriata J.L.Clark is a subwoody subshrub with tubular yellow flowers with purple striations from southern Ecuador. A broad circumscription was initially published that included Columnea lophophora Mansf. and the
two newly described species here. The updated circumscription of three species from what was previously considered one species is based on the first collection of Columnea lophophora since the early 20th century, helping to resolve the circumscription and taxonomic boundaries of collections
previously considered conspecific. Morphological characters and molecular phylogenetic analyses based on nrDNA ITS are presented that strongly support the circumscription of these three taxa as separate species. Based on IUCN guidelines, a preliminary conservation status is assigned as Endangered
(EN) for Columnea flavostriata, Vulnerable (VU) for Columnea machupicchuensis, and Vulnerable (VU) for Columnea lophophora.
ACOUSTIC EMISSION OF WATER DROPS IMPACTING ON A HEATED SURFACE
Authors: Bertola Volfango
Published: June 2024

The sound generated by the impact of water drops on heated surfaces is studied experimentally, with the purpose to identify the sound features characteristic of the various impact morphologies. Although the sound of drops impacting on liquid surfaces has been investigated extensively, little
attention was given to the sound of drops on solid, heated surfaces. The identification of sound features specific to different impact morphologies would enable the impact regime recognition without the need of high-speed imaging visual inspection and can be used to train machine learning
algorithms for automatic impact regime detection. Water drops were generated from a hypodermic needle suspended above a polished aluminum surface at temperatures between 100 and 400°C, with impact Weber numbers ranging from 30 to 150. The sound generated upon impact was captured by a supercardioid condenser microphone and compared to high-speed video recordings of the impact. Results suggest different impact morphologies generate a sound with distinctive spectral features.

Authors: Swamy Naga Ratna Giri Pallapothu , Rathish Kumar Pancharathi
Published: June 2024

In recent years, widespread availability of large datasets has propelled the application of artificial intelligence and machine learning (ML) across various engineering domains. The study focuses on developing an optimised ML model to predict the strength of normal and high-strength concretes, utilising a comprehensive dataset comprising around 900 concrete mixes. Regression tools are employed to analyse the dataset and identify the most suitable regressor for accurate strength prediction. Performance indicators are then utilised to optimise the ML model on both training and test datasets. Results indicate that the random forest (RF) regressor, along with the XG Boost regressor, demonstrate strong correlation with the trained dataset. Validation based on experimental results from 50 laboratory concrete mixtures highlights the superiority of RF regressor's with low mean percentage error and superior standard deviation compared to other ML models.

Authors: Charykova Olga G. , Salnikova Elena V.
Published: June 2024

Subject. The issues of spatial development of the fruit and berry market become especially important due to the increasing asymmetry in the development of administrative-territorial units of the state, strengthening of globalisation processes with simultaneous regionalisation and integration of markets. They lead not only to changes in socio-economic components, but also have a significant impact on the development of space, leading to its transformation.Objectives. To enhance theoretical provisions concerning the spatial development of the fruit and berry market and to determine the trends in the spatial development of this market in Russia. To propose measures to improve the efficiency of fruit and berry market development in terms of the spatial aspect.Methodology. We used the following methods of scientific knowledge to achieve our goals: dialectical; analysis, synthesis, and comparison. In the process of research, various literature sources were studied: periodicals, monographs, and statistical digests.Conclusions. Conclusions were drawn about the spatial development of the fruit and berry market as a combination of changes that improve food supply to the population of certain territories. The research revealed significant spatial differentiation in both production (supply) and consumption (demand) of fruits and berries.

Published: June 2024

Subject. The article examines issues related to the organisation of audits and audit methods used to validate that all customs payments were duly calculated, recorded, and paid. Currently, these control measures are carried out separately by customs authorities, tax inspectors, and external or internal auditors. Such an approach reduces the effectiveness of audits and does not provide for the minimum level of audit risk. Therefore, this article substantiates a systematic approach to tax audits with regard to customs payments from the perspective of all stakeholders in tax relations. Objectives. To provide recommendations related to the organisation of tax audits and methodology of tax audits related to customs payments in the context of the modern digital economy and risk-based audits. Research methods. To achieve the goals, the scientific methods of analysis, synthesis, classification, and systematic approach were used. The research was based on the study of the current regulatory framework, relevant economic research papers and journals, and factual materials. Results. The authors of the article carried out an overview of the definition of “tax audits” and proposed their own definition in the context of audits of customs tax payments. The characteristics of various levels of tax audits with regard to customs payments were systematised to validate that all customs payments were duly calculated, recorded, and paid. Conclusions. It was concluded that currently there is no systematic approach among scientists to the definition of “tax audits”, as well as to its organisation and methods. The obtained results can be used for further development of ideas about tax audits with regard to customs payments which, in their turn, can contribute to making informed and effective decisions in the area of administration of taxes and levies.
Methodological approaches to assessing the digitalisation of public administration and public services
Authors: Mikhulya Denis Yu.
Published: June 2024

Subject. Digitalisation is a global trend in the evolution and transformation of public administration systems. The developed methodological approaches, which allow assessing the effectiveness of this process and determining its impact on the socio-economic dynamics of states, strive to catch up with the rapid development of modern information and communication technologies. What is more, the government often acts as a driving force for the introduction of these technologies. The existing international, national, and regional methods of assessment are based on criteria and indicators which depend on the analytical purposes. Such criteria are developed within different databases and focus on different aspects of the digitalisation of public administration. It is important to analyse and monitor the outcomes and conditions of digital processes in public administration as well as the demand for them. Such analysis and motoring contribute to information management required for the implementation of other state functions.Objectives. The research is aimed at achieving the following research objectives: to analyse the state of the existing system of assessment of digitalisation in the area of public administration with due account of current assessment trends, to determine the advantages and disadvantages of the existing methods, to develop an original approach to their classification, and to search for optimisation opportunities. Methodology. The dialectical method and the methods of analysis and synthesis were used to achieve these objectives. The study is based on the contemporary achievements in the methods for assessing the digitalisation of public administration described in relevant research papers and regulations.Conclusions. The peculiarities of existing methods for assessing the digitalisation of public administration are due to both the peculiarities of the analysed object and the needs of the users of the analytical information. In this regard, we propose an original classification of assessment approaches, which consists of the following groups of methods: methods that assess the digitalisation conditions (group 1), the results of digitalisation in terms of available public services (group 2) and in terms of satisfaction of the main stakeholders: the public, businesses, state bodies, government agencies, and their employees (group 3). As a way of optimisation, it was considered whether it would be relevant to include indicators of the use of artificial intelligence technologies in public administration.
Сфера действия публичного договора
Authors: Gromov Andrey
Published: June 2024

До настоящего времени сфера действия публичного договора остается не до конца проясненной. В российской доктрине и практике сформировался устойчивый подход, согласно которому перечень публичных договоров не ограничивается случаями, специально упомянутыми в законе. Любой договор может быть признан публичным, если он подпадает под абстрактные критерии ст. 426 Гражданского кодекса Российской Федерации. При этом в российской литературе до настоящего времени отмечается, что ряд характерных черт, свойственных публичному договору, установить довольно трудно. Это касается, например, таких элементов, как характер деятельности обязанного лица и круг лиц, обладающих правом требовать заключения договора и обозначенных в ст. 426 Гражданского кодекса в качестве потребителей. В связи с этим крайне значимой задачей является четкое определение признаков публичного договора. Для достижения указанных целей в статье используется как анализ российской судебной практики и доктрины, так и опыт германского правопорядка, в рамках которого содержательное наполнение общей обязанности заключить договор имеет довольно давнюю историю. В статье также обращается особое внимание на то, что обязанность заключить договор с каждым, кто обратится, может иметь по меньшей мере три самостоятельных обоснования: намерение правопорядка предоставить лицу конкретное благо, требование равного обращения и запрет дискриминации по определенным критериям. Публичный договор по большей части связан с первым из трех приведенных обоснований, что существенно влияет на такой признак публичного договора, как характер деятельности обязанного лица. Автор приходит к выводу, что публичный договор служим двум различным целям: обеспечению обычных потребностей участников оборота и защите конкуренции. Данная двойственность приводит к тому, что признаки публичного договора несколько отличаются в зависимости от того, какую из двух указанных целей публичный договор обеспечивает в рамках конкретного договорного отношения.
Особенности собирания уголовных доказательств, находящихся за рубежом
Authors: Klevtsov Kyrill
Published: June 2024

В статье рассматривается ряд особенностей как организационно-правового, так и процессуального характера формирования доказательств по уголовным делам, находящихся на территории иностранных государств. Целью автора является перечисление и изучение всех законных способов получения уголовных доказательств из-за рубежа. Использованы материалистическая диалектика, юридическая герменевтика (правовая экзегеза), специально-юридический, сравнительно-правовой методы, социологический подход и метод прогнозирования. Показано, что выбор способа собирания доказательств, находящихся за рубежом, напрямую зависит от обстоятельств международного сотрудничества и самой доказательственной информации. Автор приходит к выводу, что на сегодняшний день собирание экстерриториальных уголовных доказательств возможно посредством использования механизма взаимной правовой помощи по уголовным делам или правоохранительного содействия, в том числе путем создания совместных (международных) следственных групп, оказания консульской правовой помощи по уголовным делам, а также в ходе непосредственного производства следственных и иных процессуальных действий на территории иностранных государств. Кроме того, предпринята попытка проанализировать особенности и трудности получения электронной информации по уголовным делам, которая располагается за рубежом. Автором дан краткий обзор положений так называемого «Облачного закона», принятого в Соединенных Штатах Америки. В качестве эмпирической базы исследования использованы материалы уголовных дел, приговоры российских и иностранных судов, а также документы ведомственного характера и международных организаций.
Сравнительный анализ опыта введения налога на цифровые услуги в зарубежных странах
Authors: Ponomareva Karina
Published: June 2024

Отношения в сфере налогообложения подвержены серьезным изменениям, обусловленным новыми вызовами, поскольку выступают непосредственным следствием экономической активности субъектов хозяйствования. Проблемы, возникающие при налогообложении деятельности цифровых компаний за рубежом, являются характерными и актуальными для России. В настоящее время международная налоговая координация не может отождествляться лишь с традиционными соглашениями об избежании двойного налогообложения. Многие юрисдикции начали формулировать односторонние правила налогообложения цифровой экономики. Несогласованность этих правил, вероятно, увеличит налоговое бремя на ряд транснациональных корпораций, так как каждое государство стремится защитить свои интересы. Необходимость обеспечить в таких условиях соблюдение фискальных интересов государства как в ближайшие годы, так и в долгосрочном периоде, требует трансформации сущностных подходов к нормативно-правовому регулированию системы налогов и сборов, принципов налогообложения, элементов налогообложения, налогового администрирования. Данное исследование направлено на определение фундаментальных теоретических подходов к правовому обеспечению фискальных интересов государства в условиях цифровой трансформации экономики, а также разработку рекомендаций по созданию эффективной модели правового регулирования налогообложения цифровых услуг в России. Необходимо выявить, являются ли правила налогообложения цифровых компаний и услуг существенно отличными от правил налогообложения традиционных предприятий. Кроме того, в статье прослежена трансформация подходов к самой категории цифровой услуги, к разграничению товаров и услуг в эпоху цифровой экономики: если раньше программное обеспечение рассматривалось как товар при реализации на бумажном носителе, то сегодня аналогичная категория признается услугой, поскольку ее оказание не требует физического носителя. В  статье выявлены правовые вызовы фискальным интересам российского государства, связанные с изменениями в формах и инструментах международного регулирования налогообложения прибыли цифровых бизнес-моделей и развития односторонних налоговых мер как альтернативы этим проектам. Рассмотрены этапы формирования законодательства о налогообложении цифровых услуг в зарубежных странах. На основании сравнительно-правового анализа законодательства государств, в которых введены цифровые налоги, разработаны возможные сценарии развития налогового регулирования в России.
