The TikTok live-streaming commerce trend is swiftly gaining popularity in Indonesia, with numerous local fashion brands effectively capitalizing on this opportunity to boost their sales within a short timeframe. Previous research suggests that impulsive buying behavior serves as the underlying factor for this phenomenon. Hence, this research was carried out to investigate consumer behavior in live-streaming commerce, aiming to assist small-scale fashion businesses in enhancing their sales. The Stimulus Organism Response (SOR) Model uses price promotion, promotion time limit, streamer-consumer interaction, and consumer-consumer interaction to influence the consumer’ impulsive buying by perceived risk. The quantitative approach collected 445 data from Indonesia TikTok active users who have watched a fashion broadcast and have purchased during the broadcast. The result found that perceived risk significantly affects consumer impulsive buying behavior. The price promotion, promotion time limit, and consumer-consumer interaction were found to have a strong influence on perceived risk. Then, perceived risk-mediated promotion time limit and impulsive buying decision. It means that promotional time limits indirectly affect impulsive buying decisions. Thus, developing effective price promotion, promotion time limit, and consumer-consumer interaction strategy to drive their perceived risk making a purchase, and arrange an impactful promotion time limit tactic.

Published: March 2024

High demand of tourism services in Indonesia has increased the number of travel agency businesses. However, conventional travel agencies must face difficulties by competing with Online Travel Agents (OTAs). This study aims to investigate the impact of communication strategy using the AIDA model on social media marketing strategies in enhancing brand awareness of traditional travel agencies and purchase intention. 420 respondents who have acquired conventional travel agency services via social media filled out the e-questionnaire and became the sample of this study. Data analysis was done using the partial least square structural equation modeling (PLS-SEM) method. This study found a positive relationship between communication strategy using the AIDA model and its impact on social media marketing. A positive correlation between brand awareness and purchase intention to social media marketing was also found. The findings of this research can be utilized by traditional travel agents to reorganize their marketing strategies through social media to increase brand awareness and purchase intention so that they will be able to compete with OTAs.
Укорінення vs викорінення: людяність, справедливість та деколонізація життєвого світу в часи війни
Authors: Muliarchuk Yevhen
Published: March 2024

У статті розвивається концепція укорінення як основи життєвого світу й ідентичності людини. Розкрито загрози життєвому світу й ідентичності внаслідок руйнування довкілля і культурної традиції як свідомих практик агресора з метою подолання спротиву і викорінення народу з власної землі. Антитезу «укорінення» та «викорінення» показано як внутрішню сутність боротьби у воєнний час. Укорінення виявлене як моральний чинник: «укорінений – не викорінює» (С. Вейль). Викорінення показане як загальна колонізаторська і злочинна практика, відповідальність за яку покладається не лише на виконавців, а й на тих, хто виявляє з нею згоду або байдужість. Анонімне зло війни розкрите як таке, що підважує людяність і не має залишатися без покарання. Відновлення справедливості аргументовано як умову збереження ціннісного порядку і людяності у світі. Мир подано як ситуацію, в якій переможець і переможений розуміють моральне значення подій війни та її справедливі наслідки.
Мистецтво естетичне чи політичне, Г. Лессінг між Платоном та Арістотелем
Authors: Bohdan Pavlo
Published: March 2024

У статті здійснено аналіз досвіду античної Греції у напрацюваннях Платона та Арістотеля щодо державної, а спочатку громадянської, цензури щодо виробів мистецтва, а також роль чуттєвого сприйняття, образу, суспільного ідеалу, цілісності оформлення свідомості людини на спосіб її існування у суспільстві. У статті показані дві основні тенденції щодо первинності чи вторинності мистецького виховання в державі. Розглянуто теоретичне осмислення ролі образної чуттєвості в побудові свідомості народу, яке було зроблено Г. Лессінгом в аналізі меж між мистецтвом скульптури та поезії. Як висновок, ми маємо узагальнення у вигляді чуттєвості, образу, мислення відносно індивіда, а також досвіду, мистецтва, науки відносно становлення культури взагалі як суспільних форм діяльності індивідів. У зв’язку з нерівномірністю складу самого суспільства, поглибленням розподілу праці у ньому, ми маємо і розчленованість, різноманітність чуттєвості, образності мислення в різних прошарках суспільства, що і призводить до появи інституцій цензури як зовнішнього закону стосовно громадян. Ця проблематика дає нам змогу виявити суспільну сутність чуттєвості індивіда, а цензуру – як спробу зовнішнього утримання цілісності світобачення індивіда всередині держави.

Становлення Служби військового капеланства України з моменту здобуття Незалежності в 1991 р. проходило складні етапи, які тісно пов'язані із соціокультурними трансформаціями всього українського суспільства. Після подій Майдану 2014 р. народ України остаточно обрав шлях євроінтеграції і розпочав боротьбу за розвиток у великої родині цивілізованого світу. Поступово всі суспільні та державні інституції почали процес реформи внутрішніх структур з метою наближення до стандартів європейських суспільств. Безпосередньо перед початком повномасштабної військової агресії російської федерації проти України, в Службі військового капеланства відбулися важливі зміни, які наблизили її внутрішню структуру до стандартів збройних сил закордонних держав. За рік існування Служби і роботи військових капеланів в бойових підрозділах Збройних Сил України набувається досвід, який поступово дає можливість проводити оцінку ефективності механізмів діяльності та управління. Представлена стаття є науковою рефлексією особистого досвіду автора, який проходить військову службу в Збройних Силах України на посаді військового капелана одного з бойових підрозділів. Діяльність військового капелана в межах сучасного інституту військового капеланства Збройних Сил України і одночасно в умовах виконання бойових завдань підрозділом, дає можливість зафіксувати та осмислити фактори і чинники, які знижують ефективність діяльності військових капеланів, або унеможливлюють її подальший розвиток. Змістом цього дослідження, є визначення інституційних та адміністративних чинникив неефективної роботи військових капеланів та пропозиції управлінських рішень до їх подолання
Interpretation of Revelation 13 in the writings of Ellen White
Authors: Kuryliak Bohdan
Published: March 2024

The origin and development of the Adventist Church was based on eschatological interpretations of the apocalyptic books of the Bible. Ellen White, one of the co-founders of the Seventh-day Adventist Church, played a prominent role in the interpretation of prophetic texts. In this article, I highlight her interpretation of one of the most controversial passages in the book of Revelation – the thirteenth chapter – in which John writes about the Antichrist. I show that Ellen White took a historical approach to the interpretation of apocalyptic prophecies. White interpreted the beast from the sea as a symbol of the papacy, and the beast from the earth as a symbol of Protestant America. White argued that the image of the beast would be a separate authority, a union of church and state in the United States, a kind of counterpart to the papacy. The restoration of the power of the papacy and its alliance with Protestantism will lead to the loss of religious freedom and persecution. The article highlights that the mark of the beast, according to Ellen White, symbolizes the celebration of Sunday – a false and idolatrous Sabbath. This spiritual sign will be activated in a future eschatological spiritual battle that will take place in the matter of worship and faithfulness to God’s commandments. White wrote about Sunday laws in the historical context of the United States, where they were hotly debated and even passed in some states. I argue that White was not limited by historical context, but was making a statement about future Sunday observance legislation on a worldwide scale, with other countries following the US’s example. The article shows that Ellen White also interpreted the Antichrist individualistically, by indicating the personal appearance of the devil in the form of Jesus Christ at the end of time.

Pakan dari pelet ikan komersial harganya relatiif mahal sehingga perlu dlakukan upaya pembuatan pelet dari bahan baku yang melimpah dan murah, seperti pemanfaatan limbah ikan di Pasar Tradisional Atambua. Tujuan dari penelitian ini adalah untuk membuat pakan pengganti pellet yang berasal dari limbah ikan. Penelitian ini dilakukan dengan metode kualitatif dengan pedekatan studi literatur. Data yang diperoleh dari hasil studi literatur digunakan sebagai hasil dari penelitian ini.  Hasil dari penelitian ini adalah limbah ikan hasil tangkapan yang sudah direbus, dikeringkankemudian digiling ini dicampur dengan tambahan lain seperti tepung tapioka, dedak jagung dan vitamin konsentrat. Pakan yang hampir jadi ini tidak bisa langsung diberikan kepada ikan lele karena mengandung racun berbahaya yaitu aflaktosin. Maka itu perlu dilakukan fermentasi dengan dicampur ragi tempe serta ditambahkan irisan daun papaya guna mencegah senyawa aflaktosin. Dengan begitu limbah hasil tangkapan yang merusak ekosistem dapat dimanfaatkan oleh masyarakat.

The article substantiates the relevance of the study of financial and legal regulation of hotel and tourism business. Arguments proving that hotel and tourism business, as a component of the real sector of economy, objectively has its own characteristics, both at the micro- and macroeconomic levels, are presented. The identification and research of the financial and legal levers of regulation of hotel and tourism business for restoration and development of this sphere of activity have been carried out.
The problems of the complex analysis of financial and legal regulation of the activities of hotel, restaurant, and tourism business enterprises and ways to solve them are outlined, which will contribute to ensuring the financial stability of the hospitality sector in the long term. It is substantiated that despite the presence of a large number of various legal acts that regulate the work of tourism, recreational, and restaurant enterprises, there is no single system of their interconnection and comprehensive action. It has been determined that ensuring the financial stability of hospitality enterprises is impossible without a thorough and high-quality legal framework that would fully regulate and establish the rules and obligations of all participants in the market of hotel, restaurant, and tourism services.
An assessment of the net profit (loss) of the enterprises of the hotel and restaurant business of Ukraine has been carried out, as well as of the financial results before taxation by types of economic activity in the sector of temporary accommodation and catering. As evidenced by the analysis carried out in the article, state financial support for innovative activity of hotel and restaurant business and obtaining financial monetary resources are very problematic, especially in modern conditions with a constant deficit of the state budget.
The significance of formation of legal competences of specialists in the international hotel and tourism business is emphasized as a crucial component of their professional training, and the matrix of competences and program results from the international legal regulation of hotel and tourism business has been analyzed. It has been proven that during the training process it is essential to focus on the practical aspects of application of legal norms in real situations that arise in hotel and tourism business. This will help students develop not only theoretical knowledge, but also the skills to solve specific legal issues that may arise in their professional activities. The importance of taking into account changes in the legislation and the practice of regulation of the international hotel and tourism business, as well as ensuring the constant updating of students’ knowledge in this direction, is also emphasized. Measures to overcome the crisis in the post-war recovery of the hotel and tourism business in Ukraine are highlighted.

The subject of the study: mission-oriented policy in the field of science, technology and innovation, to achieve the SDGs in Ukraine.
Purpose: defining the STI policy missions (priority directions) to respond to societal challenges and SDGs; developing the roadmaps for STI policy missions as a tool ensuring their coordination with strategic documents’ measures regarding the SDGs achieving.
Methods: policy analysis, foresight research, statistical and scientific-metric analysis, business and information analytics.
Results of the work: The objectives of six policy missions in the STI field were determined based on the foresight study, analysis of challenges, scientific and technological potential and stakeholder consultations. For the first time, six STI for SDGs roadmaps were developed for six concrete missions according to a single structure, which includes the situation and trends analysis in the relative sectors, scientific and technological and entrepreneurial potential, the key strategic documents’ measures for the SDGs implementation. The road map content has been agreed with 17 interested authorities. A comprehensive STI for SDGs roadmap has been developed as a toolkit for coordinating regulatory, organizational and financial measures regarding SDGs in Ukrainian strategic documents with the STI policy tools. The research results are the basis for determining the priority directions for the development of science and innovative activities for 2023, approved by the resolutions of the Cabinet of Ministers of Ukraine No. 283 of March 30, 2023 and No. 463 of May 9, 2023.
Scope of application of the results: legal regulation in the STI field, transformational innovation policy.
Conclusions. Defining the tasks of six policy missions in the field of STI to respond to national challenges and SDGs allowed for a more thorough analysis of the problems and risks of not achieving the SDGs and their relations with the strategic policy planning in the relevant sectors. The mission-oriented STI for SDGs road map becomes a more effective tool for coordinating the priority directions (missions) of the STI policy with measures for their implementation in strategic development documents.
Further research will be aimed at strengthening the roadmap’ coordinating role during the implementation of STI policy measures and tools in the sectors of the national economy, as well as developing the appropriate indicators for monitoring and evaluating the progress in the STI for SDGs roadmap implementation.

Authors: Tsvigun Anatoly , Semysal Anna
Published: March 2024

Introduction. The current state of economic relations in the dairy sub-complex of Ukraine is characterized by low efficiency, imbalance and limited diversification of organizational and economic forms of their implementation. Note that the problem consists in determining the main ways of improving the system of financial and economic relations between all participants of the technological chain of production of the final products of the dairy sub-complex in order to increase the socio-economic efficiency of this process.
Goal. The purpose of the study is to develop practical recommendations for increasing the efficiency of the sale of milk by farms of all forms of management to milk processing enterprises in the conditions of the introduction of martial law in the country.
Method (methodology). The following methods of scientific research were used to fulfill the tasks: induction and deduction - to highlight the main types of efficiency and interpret the concept of general efficiency; analysis and synthesis - to single out the "production - processing of milk" system in the structure of the dairy sub-complex and to single out from the set of institutions of the infrastructure of the dairy sub-complex those that directly affect the functioning of the "production - processing of milk" system; economic-statistical method (dynamic series, analytical grouping, etc.) - to establish the trends of changes in individual indicators of the functioning of the dairy sub-complex.
The results. In the current difficult time for all participants in the milk trade, there is a violation of interaction, especially between processors and trade. Thus, wholesale and retail trade enterprises, continuing the practice of non-payment, create a serious problem that leads to a chain reaction, which will negatively affect the development of the dairy sub-complex as a whole. This circumstance requires the adoption of the draft Law of Ukraine "On Trade", which would solve the above-mentioned urgent problem.
