Published: December 2020

Анотація. З огляду на необхідність визначення напрямів подальшого вдосконалення механізму справляння єдиного соціального внеску (далі — ЄСВ) з урахуванням викликів і загроз, пов’язаних зі зростанням дефіциту Пенсійного фонду України, особливої актуальності набуває аналіз здійснених упродовж 2015—2017 років реформ зазначеного податкового платежу в контексті їхнього впливу на рівень тінізації заробітних плат у країні.
Досліджено питання наукового обґрунтування доцільності зниження ставки ЄСВ з метою зменшення рівня тінізації оплати праці. Здійснено оцінку реформи ЄСВ в Україні 2016 року в контексті її впливу на рівень тінізації заробітних плат і неформальної зайнятості населення, що дало підстави для висновків про відсутність суттєвих її позитивних ефектів. Незначне зниження зазначених показників не є зіставним із негативними наслідками, які ця реформа мала для надходжень до Пенсійного фонду України. Проведено розрахунки податкового навантаження на оплату праці в Україні у 2010—2019 рр. Установлено, що 2016 року податкове навантаження на працю, порівняно з 2015-м, знизилось до рівня 28,58 %, однак у наступні роки відбулося його незначне зростання — до 30,16 % 2019 року. Обґрунтовано, що кардинальне зниження ставки ЄСВ не стало стимулом для роботодавців до детінізації заробітних плат. Адже ініціюючи реформу, вітчизняний законодавець не врахував низку неподаткових факторів детінізації заробітних плат, пов’язаних, зокрема, з якістю вітчизняного законодавства і регуляторної політики, рівнем корупції. За умов наявності в роботодавців можливості приховувати реальну кількість працівників і розмір їхніх заробітних плат, неможливо розв’язати проблему неформальної зайнятості та тінізації оплати праці лише за рахунок зниження ставки ЄСВ. Наголошено на необхідності застосування системного підходу до оцінки можливих наслідків майбутніх трансформацій ЄСВ щодо їхнього впливу на податкове навантаження на працю в розрізі усіх його складових, а також з урахуванням неподаткових факторів детінізації заробітних плат.
Ключові слова: ЄСВ, реформа ЄСВ, ставка податку, податкове навантаження на працю, детінізація заробітних плат, неформальна зайнятість.

METHODOLOGICAL APPROACHES TO ESTABLISHING A LIFE ASSURANCE GUARANTEE SCHEME IN UKRAINE
Authors: Shevchuk O. , Lezgovko A.
Published: December 2020

Abstract. The article investigates the features of creation, implementation and functioning of life assurance guarantee schemes. Based on the analysis of Ukrainian experience with insurers’ failure during 2011—2019, as well as other mechanisms of policyholders’ protection (internal risk-management, reinsurance, risk-based prudential supervision, early interventions, policyholders’ priority in winding-up process), the article proves the necessity of insurance guarantee scheme (IGS) as the last-resort protection, especially in case of long term life assurance in Ukraine.The expected guarantee costs for Ukrainian insurance market are calculated in compliance with Solvency II capital requirements. The expected losses of the system in the event of failure as a proportion of remaining insurers’ gross premiums for various asset shortfalls are estimated. Considering high concentration in life insurance market of Ukraine, it is revealed that possible losses due to the insolvency of the first four life insurers in Ukraine (from Top-10) are crucial for both the market and the guarantee scheme, despite the fact that the total expected costs of IGS appear relatively small, making up 0.35—0.45% of life assurance gross premiums (in 2019). This is typical for small and concentrated insurance markets, especially if more than 96% premiums are collected by top ten insurers, which make up only half of the market.
When established, policyholder protection funds should be designed carefully to minimise any drawbacks, particularly the moral hazard problem and the burden on soundly managed member companies. The key features of an effective IGS for Ukraine are offered. It has been proven that any IGS initiatives should be delayed in Ukraine until proportional regulation that reduce the risks of insurance companies is introduced and prudential supervisory regime Solvency II implemented.

EMPLOYER BRANDING IN FORMATION OF THE INTELLECTUAL CAPITAL OF THE TOUR OPERATOR: THE CASE STUDY OF UKRAINE
Authors: Mykhailichenko H. , Kravtsov S. , Melnychenko S. , Vedmid N. , Zabaldina Yu.
Published: December 2020

Abstract. The article defines that intellectual capital should be considered as one of the key factors of successful realization and provision of tourist services when the level of material stocks and raw materials resources reduce. The main feature of effective tour operator’s business is the formed intellectual potential, first of all, the staff, which has value-oriented professional knowledge, ambition, creativity, and the efficiency of each employee’s work is the key source of innovative changes for any enterprise. The accumulated knowledge and experience transform the staff into intellectual capital that is the resource of growth and development of tour operators. In such a situation, the administration of the tourist enterprises should use efficient tools for attracting professional employees, which are the basis of the intellectual capital of the company. However, the results of a survey among Ukrainian students who study in the field of tourism indicate a passive position of leading tourism operators’ directors in the process of finding and attracting tourism industry professionals to work for these companies. The directors of tour operators do not pay attention to HR brand formation that by the way generates the overall image and reputation of the tourist company. As a result, we have a significant staff turnover in companies that are in the top 10 leading employers in the tourism sector. It is an obstacle to form intellectual capital of organizations, that affects the performance. On other hand, well-formed employer brand enhances the company reputation, which is a proven mechanism for evaluating the partnership’s stability and business strategy. The right policy for the human resources formation creates a special professional intellect, and if tour operators use it, it transforms into intellectual capital for the firm and into intellectual property for the employee. The successful implementation of co-branding (a joint brand «employee company») enhances the image and reputation components that are intended to ensure stable positive financial results that is the most important condition for strategic company development, even in the conditions of fierce competitive struggle.
Keywords: intellectual capital, tour operator, reputation capital, co-branding, HR-brand.

Published: December 2020

Анотація. Побудова високоефективної національної інноваційної системи передбачає розвиток державної наукової діяльності та інноваційної діяльності промислових підприємств. Мета дослідження — визначити вплив упровадження інновацій на зростання фінансових ресурсів підприємств. Розгляд літературних джерел засвідчив, що підприємства, які впроваджують інновації з метою вдосконалення своїх процесів та диференціації своїх товарів і послуг, значно випереджають конкурентів за ринковою часткою, якістю, гнучкістю процесів виробництва та обслуговування.
З метою всебічного вивчення впливу інноваційної діяльності на прибутковість підприємств було досліджено взаємозв’язок між узагальненими показниками реалізованої інноваційної продукції, валовою доданою вартістю і валовим прибутком підприємств.  Результати проведеного аналізу показали, що інноваційна діяльність є важливим фактором економічного зростання підприємств. Було встановлено, що виробництво інноваційної продукції сприяє зростанню фінансових результатів підприємства. Для аналізу загальних показників ефективності інноваційної діяльності підприємств України було також проаналізовано залежність обсягу реалізованої інноваційної продукції від загального фінансування інновацій, було виявлено низький рівень ефективності інноваційної діяльності українських підприємств, що є негативним фактором, який стримує фінансове зростання підприємств. Аналіз діяльності промислових підприємств, які здійснювали інноваційну діяльність, дозволяє зробити висновок, що у структурі діяльності інноваційних напрямів відбулися значні зміни. Важливим завданням інноваційного розвитку промислових підприємств сьогодні є впровадження нових технологій виробництва і зберігання, що дають змогу створювати якісну та безпечну продукцію. Для залучення іноземних інвестицій підприємствам важливо розвивати інновації, які розв’язують глобальні економічні, промислові, соціальні проблеми.

Authors: Ivanechko N. , Borysova T. , Monastyrskyi G.
Published: December 2020

Abstract. Such key innovations as renewable energy and electric transport are being broadly deployed in the world nowadays. Interest of the consumer market in electric vehicles has increased for the last 5 years. The article analyzes the market for electric vehicles from the point of view of marketing, since the analysis of sources that consider marketing of innovations shows that insufficient attention is paid to the issues of marketing activity and marketing tools in the market of electric vehicles. The purpose of the article is to explore the Ukrainian market for electric vehicles, identify the use of marketing tools and offer new ones which could be effective and relevant for the modern consumer market of Ukraine. Two types of marketing information, namely, primary and secondary data, have become the basis for the study. When collecting primary data, the main criterion for the selection of respondents was their age according to Generation Theory. Generation was identified as a population of people born in the span of 20 years. Thus, Generation X (over 40), Generation Y (20 to 40), Generation Z (up to 20) were covered in equal parts, accounting for 33.3% of the sample. The survey was conducted using the method of questioning with open and closed questions on the basis of confidentiality. Secondary data are based on empirical studies of market experts, professional community sites, and official statistics. Based on the results of the study, the authors have concluded that at present car companies that produce and sell electric transport do not conduct active marketing activities in the Ukrainian market and do not pay attention to marketing tools. As a consequence, many potential buyers are unaware of the benefits and capabilities of an electric vehicle and do not intend to purchase one. It is suggested to use differentiated marketing tools, based on the model of consumer behavior of generations. Along with the scientific value, the results of this study can be used by marketers of automobile companies to develop a profile of a potential buyer of an electric vehicle in Ukraine and formulate marketing plans aimed at definition and selection of marketing mix.

Published: December 2020

The use of wind energy is a decisive factor for human development, associated with the environment and capacity of people exploiting this vital resource. The investigation is part of predicting the behavior of the temperatures inside the nacelle of the Goldwind wind turbines S50 / 750 models installed in the Gibara Wind Farm. It supports its theories and analysis of computer-aided design (CAD), by monitoring the working temperatures, which interact with the forced ventilation system in the studied devices. The values analyzed result from continuous measurements carried out by the SCADA systems (Supervisory Control and Data Acquisition) of the studied machines. Which allows the diagnosis and early visualization of unforeseen incipient failures that currently occur under operating conditions standardized by the manufacturer. When the wind reaches speeds that exceed 11.5 m/s, major aggregates such as the gearbox and the generator fail. The results obtained in the investigation will allow to correct the program in the PLC (Logical Control Program) for the start-up and stop of the cooling system of the wind turbines in order to generate an ideal thermal balance for the working condition activities in Cuba, inside the nacelle, reducing the frequent occurrence of critical temperature values in the maximum limit that put the wind turbines out of service and therefore providing the wind farm with a higher coefficient of technical availability.

Published: December 2020

Known to have a long history of timber extraction, Mursala Island on the west coast of North Sumatra Province is a small island home to the endemic tree Dipterocarpus cinereus and many other Dipterocarpaceae species. In the present study, distance sampling using line-transect was used to assess the species diversity and population status of Dipterocarpaceae species on the Island. A total of 26 Dipterocarpaceae species from 6 genera was identified from Mursala Island. The genus that was represented by the highest number of species was Shorea (13 species), followed by Vatica (5), Dipterocarpus (4), Hopea (2), Cotylelobium (1) and Dryobalanops (1). Among these, two Mursala Island endemic were identified: D. cinereus and H. bancana. Furthermore, according to IUCN Red List category, 11 species (42.3%) were classified as critically endangered, four species (15.4%) were of endangered, 5 species (15.2%) were of vulnerable, one species was of near threatened, 2 species were of least concern and 3 species were not assessed yet. Based on distance analysis, the species with the highest individual density was S. multiflora (21.72±10.96 individual/ha), whereas species with the lowest density was S. johorensis (0.06±0.01 individual/ha). Two main threats for Dipterocarpaceae species in Mursala Island were observed during the survey: illegal logging and habitat conversion. Increasing the protection level of the island was recommended to conserve all the species of Dipterocarpaceae. Besides, providing alternative sources of living for the illegal logger through commercialization of non-timber forest products, ecotourism, and the sustainable fishery was recommended so that they could stop illegal logging activity.

Published: December 2020

Oil palm has many advantages, such as biofuels, cosmetics, food ingredients, etc. The amount of oil contained in oil palm fruit is very dependent on the age of the plant, so automatic detection of oil palm plantation area based on plant ages is required to estimate the amount of oil. The use of high-resolution satellite images in oil palm detection has shown promising results for small dimensions, and previous studies have used more than one band of the satellite images data. This will be a burden in terms of cost and processing. Previous studies regarding oil palm area detection usually focused on detecting land cover to distinguish oil palm and non-oil palm areas. This study proposes a method based on deep-learning convolutional neural networks to classify oil palm plantations at a productive age. The images used in this study are the Ikonos satellite image with panchromatic bands only, which have a spatial ratio of 1m. The plantation area is classified into the non-oil palm, oil palm areas with young, mature, and old ages. This study proposes a multi-class classification method for oil palm plantations based on plant ages using convolutional neural networks (CNN). This study performs two fine-tune models on a pre-trained CNN and then classified using SVM and CNN. The performance of CNN architectures such as AlexNet, VGG16, and VGG19 was compared. The highest accuracy is 94.74% when using the CNN classifier and fine-tune model-2 of the VGG19 pre-trained network.

Vobtusine is an aspidosperma-aspidosperma alkaloid isolated from alkaloid DCM base fraction of the bark of Voacanga foetida (Blume) Rolfe (Apocynaceae). In this study, the effect of vobtusine on the cell cycle, apoptosis induction, and Bcl-2 family protein expression  were investigated by flow cytometr,  DNA fragmentation analysis, and western blotting, respectively. The results of cell cycle analysis indicated the ratio of the number of cells in each phase did not have significant differences depend on vobtusine concentration although cell number in G1 phase had tendency to decrease according to the increasing of vobtusine concentration. Besides, the sub-G1 phase population of HL-60 cells treated with vobtusine was increased compared with that of cells without treatments (5.9%-23.8%). DNA fragmentation was observed from 20 µM, and the degree of fragmentation was dependent on vobtusine concentration. Caspase-3 activity increased 4.6 times compared to control. After being treated with caspase-9 inhibitor, vobtusine-induced elevation of caspase-3 activity decreased. This shows that caspase-3 activity depends on caspase-9. Vobtusine was also induced apoptotic cell death involved a mitochondrial by Bid activation and Bcl-xL downregulation. Therefore, vobtsusine-induced apoptosis process was initiated by caspase-9 via change of Bcl-2 family protein expression and executed by caspase-3, followed by cell death due to their proteolytic activity. These results indicated the mechanism action of vobtusine as anti-cancer compound via intrinsic pathway.

Published: December 2020

Indonesia is a country with the second-longest coastline globally and has the most extensive mangrove forests in the world. Mangrove forests are included in the blue carbon group, which per hectare store up to four times more carbon storage than tropical forests. Mangrove forests play an essential role in absorbing carbon emissions in the air and storing a lot of carbon compared to natural forests. This study aims to determine carbon storage and CO2 absorption in mangrove forests in Kabaena Barat Subdistrict, Bombana Regency. The data comes from direct measurements in the field, namely above-ground carbon, carried out without damaging trees, only covering carbon in tree vegetation. It is the largest proportion of carbon storage on land. The data collection used a survey method to identify mangrove species, circumference, tree trunk diameter at breast height (dbh), biomass, carbon storage, CO2 absorption, and 22 plots of plotted line method with eight transects. The results showed that 10 types of mangrove species were found on the transect observation, namely Avicennia alba, Avicennia marina, Avicennia lanata, Avicennia sp., Bruguiera cylindrica, Bruguiera gymnorhiza, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Xylocarpus granatum. With the total amount of biomass stored in Kabaena Barat Subdistrict's mangrove forests, Bombana Regency, is 6,664.93 tons ha-1 with carbon storage of 3,065.85 tons ha-1 and carbon dioxide absorption of 11,241.55 tons ha-1.
Image Classification of Tourist Attractions with K-Nearest Neighbor, Logistic Regression, Random Forest, and Support Vector Machine
Authors: Sujaini Herry
Published: December 2020

K-Nearest Neighbor (KNN), Logistic regression (LR), Random Forest (RF), and Support Vector Machine (SVM) are four methods of identification. The methods are widely used in various research in data mining, especially classifications in recent years. We have used the four classification methods in the study to classify images of five natural attractions, namely Danau Toba (North Sumatra), Nusa Penida (Bali), Raja Ampat (West Papua), Tanah Lot (Bali), and Wakatobi (Southeast Sulawesi). Our research results have concluded that the Logistic Regression method's performance has the best performance in classifying natural images as done in this research. The LR method can classify images that other methods such as kNN, SVM, and RF cannot be correctly classified. However, SVM also shows good performance by only making one error in the classification results; it can even be corrected using the Linear Kernel. In general, it is shown that the LR method has the highest precision value of 100%, followed by the method of kNN and SVM with a precision of 91.9% and RF with a precision of 81.9%. Variations of the variables used in the experiment also determine each method's precision. Chebyshev Metric has the highest precision value in the kNN method, and Ridge Regularization has the highest precision value in the LR method. The number of best on the RF method is 11, and Linear Kernel is the Kernel that gets the best precision value on the SVM method.

A Panel Analysis of Trade Gravity between Pakistan and South Asian Countries
Authors: Jan Waheed Ullah , Shah Mahmood
Published: December 2020

This paper attempts to examine Pakistan’s trade patterns with South Asian countries by using a gravity model of trade. The main objective of the study is to quantify the long‑run impacts of gravity variables. To achieve this objective, a panel data set for the period 2003 to 2017 has been used. Based on the mixed evidence of the results of panel unit root tests, Pooled Mean Group (PMG) and Panel Dynamic Ordinary Least Square (DOLS) techniques are applied. The outcome of the PMG and Panel DOLS models justifies the theoretical background of the gravity model and suggests that all the basic gravity variables haveusual signs. The RGDPs and population of both Pakistan and the partner country have a positive impact on their bilateral trade. On the other hand, the distance between the two trading countries and the exchange rate have a negative impact on bilateral trade.The uniqueness of this study is that it measures the impacts of qualitative variables along with basic gravity variables. Language similarities and common borders have a positive impact on bilateral trade. Pakistan has borders with India and Afghanistan, but their trade relations are not worth mentioning. The military conflicts between Pakistan and India, and the political suspicions between Pakistan and Afghanistan hinder their trade relations.

Specifics of logit and probit regression in education sciences - why wouldn't we use it?
Authors: Opic Sinisa
Published: December 2020

Regression is one of the dominant analysis methods used in the social sciences and educational sciences. There are different regression methods based on the type of research that is being conducted. The probit and logit regression models are regression methods which are being used recently by most researchers. However, their interpretations are not straightfoward and most researchers end up misinterepreting the results from the probit and logit regression models. This research therefore aims to examine the differences between the probit and logit models, in comparison with other linear regression models. Using a comparative research design, this study utilises resources from previous researchers, hence, the study took a form of a literature review. The results of this study is essential to educational and social sciences researchers who make use of the probit, logit and other regression methods. The research also explains why logit and probit should be used in place of other regression models.

Student and teacher engagement in Learning and assessment with portfolios
Authors: Phothongsunan Sureepong
Published: December 2020

Assessing student knowledge and success during and after teaching and learning is an embedded part of education since it offers important specifics for teachers. This action research was undertaken to inquire about students’ and teachers’ attitudes to portfolio assessment in their English courses. Two methods were employed, including a student portfolio attitude survey and a teacher survey. It was found that most students had a clear understanding regarding how a portfolio was made and admitted that the portfolio could assist them in learning how to write better in many aspects. Likewise, most teachers found the portfolio to be practical mainly in indicating students’ problems and monitoring their learning progress. Implications from the study point to the need for training students to have skills important for using a portfolio as a life-long learning tool and for encouraging language teachers to use various forms of assessment to help students engage more in learning and ensure that targeted learning outcomes are achieved.

This paper presents a study of university social responsibility (USR), carried out through an innovative educational action. The students of the studied classrooms in the University of the Basque Country (UPV/EHU) collaborated with a social entity Emmaus Social Foundation dedicated to environmental sustainability, social justice and the social and solidarity economy to provide community services through a service-learning methodology. Using a mixed method approach, we combined the practical experience of the social entity with an active student-centred teaching methodology in order to foster the acquisition of general and specific competencies related to sustainability and social justice. The aim was to create learning connections between members of the university community and links with the environmental and social reality of the Basque Country. This pilot study was carried out in the first term of the 2018–2019 academic year. This work allowed (a) critical knowledge to be generated by incorporating and hybridising discussion elements of social justice, such as sustainability; (b) intergenerational participation processes to be generated between elders, university students and social organisations in order to acquire general and specific learning competencies and (c) social and environmental needs to be addressed through community services.

LEXICAL DIFFERENCES IN GOROM LANGUAGE: A SOCIAL DIALECTOLOGY STUDY
Authors: Rumalean Iwan
Published: December 2020

The present study aims to describe and explain lexical differences in Gorom language on age and professional factors in East Seram Regency, Molucca Province, Indonesia, which employs a social dialectology approach. Data were gathered using the Identity method following the linguistics characteristics identity technique. The instrument used was all 880 basic vocabulary of Gorom language. The sources for this study totaled 24 people. Furthermore, the data analysis was done using a snowball sampling technique. The study indicated that the factor of age and profession in Gorom distinguished social dialects. In the findings, farmer and adult speakers share the same lexical forms. As seen from the age factor, both farmers and adults are about the same age, making them easier to construct mutual understanding. On the other hand, civil servants and children use the same linguistic forms. Children use civil servants' speech as a reference for the kind of prestigious speech; therefore, many Gorom children dream of becoming civil servants. Yet, civil servants and children create some linguistic innovations, such as affixation to roots. It shows solidarity among the community and self-actualization of wide-mannered socialization.
POWER IN INDONESIAN PRESIDENTIAL SPEECHES: AN ANALYSIS OF LINGUISTIC MODALITY
Authors: Jannatussholihah Siti , Triyono Sulis
Published: December 2020

This paper discusses the relationship between the language and power in the presidential speech text, which is projected through linguistic features, especially modalities. The data was obtained from a speech delivered by President Joko Widodo during the plenary session of the Indonesian People's Consultative Assembly (MPR RI) for the inauguration of the elected president for the 2019-2024 period and the delivery of the president's vision for Indonesia better. Analysis of this paper from linguistic modalities uses a three-dimensional model of Fairclough's critical discourse (CDA) analysis to answer its research questions. The results show that Jokowi used several linguistic modal verbs in projecting his strength. Based on the modality's context, it can be understood that the president conveyed his strategic desire to be himself when he tried to connect with the audience and build his image, audience, and relationship. The President produces a discourse that embodies assumptions about his leadership and audience's social relationship and affirms his legal authority as president and his power. Through the language used, Jokowi creates, maintains, and explains power he holds in these forums.

The results of mineralogical and geochemical studies of deepsea carbonate buildups dredged from areas of modern volcanism in the rift valley of the northern Atlantic Ocean were obtained for the first time. Morphology, anatomy, chemical and microelement compositions of buildups are characterized. Mineralized biofilms with bacteriomorphic structures were revealed. Using the methods of X-ray diffraction and RSMZ analysis, the main carbonate minerals of the buildups were diagnosed and studied, and the phenomenon of the anomalous nature of the isotopic composition of carbon and oxygen in them was revealed. It has been suggested that the cause of the abnormally heavy oxygen isotopic composition in carbonate buildups is the borrowing of oxygen by carbonate-forming bacteria directly from sulfates, often distinguished by isotopeheavy oxygen.
The Miocene bryozoan biogerms of the Kazantip Cape, Crimea: the role of gas-fluid seepage in their genesis

A complex of modern physical investigations of carbonate crusts covering Lower Miocene bryozoan limestone from the Kazantip Cape showed that bryozoans built a biohermal skeleton due to the synsedimentation of bioinduced cement. The mineral association (Mg-calcite + aragonite) indicates the existence of near-bottom environment typical for gas-hydrate biogenic mineral formation as a result of bacterial methane oxidation during the formation of bioherms. The presence of bitumen, pyrite, strontianite, barite, kutnohorite and traces of vital activity of carbonate-depositing methanotrophic bacteria in the composition of carbonate crusts is concerned with a significant influence of near-bottom local gas-fluid seeps.
