Authors: BEREZYUK Sergiy , TOKARCHUK Dina , PRYSHLIAK Natalia
Published: December 2022

The article is devoted to the study of the resource potential of the use of waste as a component of the environmental and energy security of the state. The problem of handling solid waste is the most urgent component of ensuring national security for Ukraine, since the volumes of accumulated waste are considered as one of the factors of the progressive environmental crisis. The sphere of secondary use of resources in Ukraine is at the stage of active formation. Due to insufficient consideration of the value of secondary resource potential, lack of awareness and lack of proper marketing, underestimation of social (for example, creation of additional jobs) and environmental factors, and also due to mismanagement, a significant part of the waste that can be used as material and energy resources is lost. The purpose of the article is to assess the potential of waste use in order to form the state’s environmental and energy security. The readiness of the citizens of Ukraine for separate collection of household waste was analyzed. The number of landfills and their area in Ukraine were determined. Technologies for the processing of municipal solid waste were characterized. The benefits of sorting and recycling solid waste were analyzed. The hierarchy of waste management priorities in the EU was built. The cost of processing recyclable materials was analyzed. An analytical assessment of the resource potential of production and consumption waste was made. Priority areas for their use have been identified. A comparative analysis of inertial and innovative scenarios for the development of the field of waste management in Ukraine for the period up to 2025 was carried out. Estimated amount of biogas that can be obtained from the annual volume of buried solid household waste was determined. SWOT analysis of implementation of the project for collecting and utilizing biogas of solid waste dumps was carried out. Proposals for improvement of the waste management structure at the state level were presented.

Published: December 2022

Tourism sector performance contributes to a large part of the Malaysian service economy (The World Factbook 2013). In 2016, Malaysia has faced an economic crisis and it affects tourism sectors. Moreover, data from the Ministry of Tourism have shown that the number of tourists is decreasing at 1.5% in March 2016. This scenario has become a serious issue for government because Tourism Sector is one of the government’s important agenda in the National Key Economic Areas (NKEA) through National Ecotourism Plan. According to the Ministry of Tourism (MoT 2013), the nation's tourism sector is now the sixth largest contributor to the national economy in 2014. Unfortunately, among of all agendas in 21 Action Plans, none of it mentions about heritage tourism. The study was done among the tourist at several heritage site in Malaysia and 200 questionnaires, were distributed. Correlation analysis and regression analysis were perform, thus the result indicates that Heritage Spending Behavior (r=0.55, p=0.001,) shows the highest of positive significant result toward Tourism Industrial Performance compared with other two variables. Lastly, it will guide the government by understanding the important need of visitors and it can apply to other heritages sites in Malaysia.

Published: December 2022

The purpose of the research is to evaluate the potential and opportunities for the development of tourist activity in the regions of Ukraine in the present context using a method of analysis of the functioning environment. Twelve regions of Ukraine were found to have high tourism development potential, but the other thirteen did not have enough revenue from tourism services to cover labor and operating costs. In Ukraine, Dnipropetrovs’k (60.5%), Ternopil’ (41.4%), Ivano-Frankivs’k (39.1%) and Chernihiv (33.3%) regions have the greatest potential for improving the provision of tourist services. The potential of other regions ranges from 23.0% to 28.2%. The level of realization of existing opportunities and the level of losses from tourist activity in the regions of Ukraine were calculated, and it is allowed to identify the high level of realization of development opportunities in the Dnipropetrovs’k region, but four regions (Kharkiv, Rivne, Poltava, Mykolaiv ones) suffered losses. The results of the study can be used in strategic and operational planning of tourism development in the regions of Ukraine and in improving the efficiency of the tourism business.

Authors: PRAPROM Chakorn , LAIPAPORN Jetsada
Published: December 2022

This study evaluated the impacts of the interrupted incidents on the monthly Malaysian tourist arrivals to Songkhla province in Thailand from January 2004 to December 2019. By applying the Seasonal Autoregressive Integrated Moving Average or SARIMA with intervention model, the estimated coefficients of the most parsimonious model, the SARIMA (1,1,0) (1,0,0)12, with intervention model, showed four categories of interrupted incidents that were significantly affected the number of arrivals. These four categories included the insurgency incidents, the political unrests, the natural disasters, and the dieses outbreaks. Most of interrupted incidents significantly decreased the number of arrivals inducing losses in tourism incomes around 370 to 1,031 million baht. However, this study surprisingly found that two insurgency incidents occurring in Narathiwat, a neighbouring province of Songkhla, significantly caused temporary increases in Malaysian tourist arrivals to Songkhla and led to the increase in the tourism income of Songkhla at around 289 million baht. Lastly, based on the estimated model, the forecasts of monthly Malaysian tourist arrivals in 2020 were in the range between 187,633 to 273,929 persons. Then, the forecast of total arrivals to Songkhla in 2020 was approximately 2,471,092 persons or 21.61 percentage increased from the total arrivals in 2019.

Accommodation as an integral part of each tour occupies a central place in the complex of services, which are offered to tourists during the trip. The question of the importance of individual accommodation facilities, their impact on the integrity of the structure of the tourism industry of the country and regions is particularly important. The research was conducted by means of interview of IAF managers and private households (PH) owners. Almost all the interviewees pointed out that the households’ owners often "hide" tourists, introducing them as relatives in order such information not to reach the Tax Service. The hotel industry needs an improvement of the material and technical facilities and further governmental help for the tourism development as well as the aligning of the seasonal misbalance of the resorts and touristic organizations occupation.

Eco-Management and Eco-Standardization in Russia: The Perspectives and Barriers for Development
Authors: RATNER Svetlana , IOSIFOV Valery
Published: December 2022

The Krasnodar Region is one of Russia's few traditional centers of tourism. The 2014 Winter Olympics in Sochi contributed to rapid development of the tourist infrastructure in the region, as well as its increased attractiveness to Russian and international tourists. An enlarged flow of tourists requires the fast development of an effective environmental policy, aimed at maintaining the quality of ecosystems in developing tourist territories. In Russia, the environmental labeling of hotels and other accommodation facilities is not yet widespread. Therefore, the main purpose of this study is to analyze the existing national regulatory framework (federal and regional legislation, standards, and voluntary certification systems, including regional ones) for identification of the most advanced ecology-preserving legal acts, which could serve as a prototype for the development of a regional system for eco-labeling in the tourist business. Secondly, we aim to analyze the attractiveness of eco-hotels for Russian tourists and their readiness to pay to for the different services in eco-hotels. To do so, we use face-to-face surveys, and process the obtained empirical data further using the methods of non-parametrical statistics. The results of the survey show that the majority of respondents (who are also tourists that visit the region on a regular basis), are poorly informed of the issues of ecologic management and ecologic labeling, as well as the issue of how intensive tourism affects the regional ecology. However, the majority of respondents still show interest in eco-hotel services, and would rather prefer to stay there if the price and the overall quality of their stay remains the same.
Coping with COVID-19 Impact on Self-Employment: Does Gender and Academic Education Matters?
Authors: THAPA Manish
Published: December 2022

In this modern age of competitiveness and the quest for sustainable income source through adoption of innovative approaches, the preference towards self-employment is ever increasing among individuals in global scenario. In Nepali scenario, as the rate of employment opportunities are comparatively low in comparison to rate of individual obtaining higher degree (above high school), rate of self-employed individuals has increased in significant manner. As financial security is not as strong as that of developed countries, self-employment sector gets affected during any unwanted circumstances which were evident during COVID-19 period as well. This paper used Human Capital Theory and Need for Achievement Theory to discuss role of gender and academic knowledge as contributing factors towards identification and adoption of coping strategies during COVID-19. With desk review and interviews with self-employed individuals, this paper strongly argues, the strategies adopted to cope with COVID-19 is more guided by enterprise type and financial backing instead of academic skill and gender.

The rapprochement of economic laws, set forth in the Treaty on the Eurasian Economic Union (EAEU), provides for the unitary standards of disseminating economic information. In the mid-1990s, Russia became a model in regulating advertising activities for the majority of the FSU (Former Soviet Union) republics. Nevertheless, the article presents substantial differences in advertisement understanding in the EAEU that can slow down the turnover expansion. It is demonstrated that even the same words can have different meaning. The paper analyzes the drawbacks in different approaches. In particular, it concludes that lawmakers do not pay enough attention to the regulation of advertisement in the new communication media. The author outlines some opportunities to eliminate the drawbacks in the process of bringing together the laws.

Indonesia is one of the countries with the longest coastline, so Indonesia has many coastal areas with all its natural resources. However, these natural resources are starting to be disturbed due to abrasion. Abrasion is known not only to occur due to natural factors but also human behavior factors. Therefore, abrasion in Kragan District, Rembang Regency must be handled immediately through participatory mapping involving the community. Research with qualitative and quantitative approaches through questionnaires, interviews, observation, and FGD techniques was conducted to collect data. The results showed that participatory mapping was effective in increasing community capacity. In addition, participatory mapping also produces a map of the hazard to abrasion, which is one of the considerations for policymakers in making decisions regarding the handling of abrasion. Community capacity and the resulting map is a provision for the community to handle abrasion properly, so it is hoped that the chances of a sustainable coastal area will be even greater.

Published: December 2022

In the last decades, aviation industry has expressed an increasing interest in the application of environmental management systems (EMSs). Many scholars have examined the environmental impact of the airports’ operations, but few have studied the management practices used to develop airport environmental policies. This study aims to contribute to academic and managerial knowledge by exploring and evaluating the application of EMS in the largest Greek airport, namely Athens International Airport (AIA). To achieve this goal, a qualitative case study was conducted in every dimension and aspect of AIA’s Environmental Management System. Subsequently, a new Airport Environmental Performance Model (AEP) was built combining the case study results with the most common benchmarking models proposed in the literature. This research enhances the understanding about the airport environmental management and offers best-practice insights to scholars and aviation professionals altogether, proposing the new AEP.

Resource Endowment of Rural Areas: Indicators, Assessment Procedures
Authors: KUSSAIYNOV Talgat , TOKENOVA Sandugash
Published: December 2022

The specific objectives of the baseline study are to (a) characterize the livelihoods of rural communities with respect to their physical, natural, financial, human, and social assets, (b) identify opportunities and key constraints to productivity and resource management, and (b) establish baseline information that could be used for the monitoring, evaluation and impact assessment of socio-economic projects in the region.

A structured questionnaire was used to obtain data through a number of visits. Around 1200 households were interviewed. It is established that there are significant imbalances in the distribution of economic resources among households. This circumstance objectively hinders the growth of the solvent potential of the rural population and hinders the economic development of rural areas. In addition, there are no organized forms of economic interaction of households in the studied region. Meanwhile, social capital in the form of a cooperative or other form of association is, in principle, a powerful means of solving socio-economic problems in rural areas, including in the supply of resources and the promotion of their own products on the market.

The results obtained highlight the major constraints and opportunities that would guide intervention projects to improve food security and reduce poverty in the survey sites.

The high potential of tourist and recreational resources is not yet a guarantee of tourism successful development, whereas it requires searching and implementing of the new and effective modern forms of entrepreneurial potential fulfillment in the tourist area. To form a competitive tourism market, it is necessary to ensure a number of tourism industry components which would enhance the quality of tourist services provision and satisfy all the needs of tourist services consumers.

The purpose of the article is the studying of the tourism industry functioning in the Russian Federation. To achieve this purpose, it is necessary to consider a number of objectives:

to determine the mechanism of the tourism market functioning;

to perform the analysis of the tourism market development by the regions of the Russian Federation;

to identify the prerequisites of the current tourism industry state in Russia;

to propose the recommendations for tourism industry regulation.

Dialectical method of scientific cognition was applied during studying the role and influence of tourism on the economy development, the calculation and analytical methods of observation, measurement, analysis and comparison of indices characterizing the tourism industry in the Russian Federation.

The regulation of the tourist regional market with the help of special economic zones allows creating conditions for attracting investments to the economy of the region, raising of living standards, reducing unemployment, etc. The current tourism industry state of the Russian Federation was studied. The dynamic pattern of socio-economic indicators of the tourism industry is reflected. The mechanism of the tourism market functioning is presented here.

To form a modern efficient competitive market of the tourism industry it is necessary to adhere to the following mechanisms of state regulation: in the development of legal, financial and economic constraints that determine the parameters for the tourism industry development; in the development of investment policies directed by the state for the priority development of the tourism infrastructure, especially in tourist areas, where the financing from their own sources is not possible; in the regulation of personnel training and retraining for the tourism industry; in measures and methods of small and medium-sized businesses support in the tourism sphere; in information assurance and advertising activity of tourist enterprises; in promotion of the national tourist product to the international tourism market; in promotion of the new national tourism products development; in standardization and certification of the tourism industry services with the use of blockchain technologies.
Insurance-markets Equilibrium with Sequential Non-convex Market-Sector and Divisible Informal-Sector Labor Supply
Authors: Vasilev Aleksandar
Published: December 2022

This  paper  describes  the lottery- and insurance-market equilibrium in an economy  with non-convex  market-sector employment  and  informal  sector  work.   In contrast  to Vasilev 2016a, the discrete-continuous labor supply decision  in this paper is a sequential  one,  and instead  of  home  production,  we focus  on informal  activity. The presence of non-convexity requires that an insurance market for market-sector employment  be put in operation to achieve  market  completeness.  In addition,  given that the labor  choice  for  market  work and informal-sector hours is made  in succes- sion,  the  insurance  market  for  market  employment  needs  to  close  before  the  labor supply choice  in the grey economy  is made.  This  timing is reminiscent of the results obtained  in Vasilev  2016b) and also  a direct  consequence of the sequential  nature  of the discrete-continuous sectoral  labor supply decision.

The role of endogenous capital depreciation rate for business cycle dynamics: lessons from Bulgaria (1999-2018)
Authors: VASILEV Aleksander
Published: December 2022

We allow for an endogenous depreciation rate of physical capital stock into a real-business-cycle model with a government sector. We calibrate the model to Bulgarian data for the period following the introduction of the currency board arrangement (1999-2018). We investigate the quantitative importance of the endogenous depreciation rate, and indirectly, the capital utilization mechanism for cyclical fluctuations in Bulgaria. Allowing for endogenous variations in the depreciation rate of capital improves the model performance against data, and in addition this extended setup dominates the standard RBC model framework with constant depreciation and a fixed utilization rate of physical capital, and a fixed depreciation rate e.g., Vasilev (2009).
An introduction to transposable Schwartz families
Authors: CARFI’ David
Published: December 2022

In this paper we start to construct some fundamental features of Dirac Calculus, specifically, we go inside the theory of Heisenberg continuous matrices, which, in our Schwartz Linear Algebra, are represented by Schwartz families. We distinguish the important subclass of transposable continuous matrices and give some basic and very important examples in Quantum Mechanics. So we define transposable Schwartz families and their transpose families, we prove the transposability of Dirac families and Fourier families. We find the transpose of regular-distribution families in a much general case. We define symmetric families, the analogous of symmetric ma- trices in the continuous case. We prove the symmetry of Dirac families and of Fourier families. We define Hermitian families, the analogous of Hermitian matrices in the continuous case. We prove the Hermitianity of Dirac families and of Fourier families. We define unitary families, the analogous of unitary matrices in the continuous case. We prove the unitarity of Dirac families and of the fundamental normalized de Broglie family. Then, we use the transpose of a family to find the components of the superpositions of transposable families, we give a general result and we apply this result to the Dirac families and the eigenfamilies of the vector-wave operator. We shall use the transposable families in next chapters to define the Dirac product in distribution spaces, basic product for the entire foundation of Dirac Calculus and Quantum Mechanics formalism.
Factory Farming and Ocean Degradation: Coopetitive Strategies for the Environment
Authors: CARFI’ David , DONATO Alessia
Published: December 2022

In this study, we propose possible coopetitive strategies between countries in order to reduce environmental problems related to the meat production. In particular, the problem of factory farming and ocean degradation is studied.

We propose a coopetitive strategy focused in investments promoting and suggesting the change of diet (reformulating food products towards a healthy diet based on vegetables) and improving the sustainability of production practices (production of plant-based food and reduction of the associated emissions).

We create a mathematical model of interaction between two players and we completely study the associated game, suggesting a possible compromise solution.
A Real-Business-Cycle model with robots: Lessons for Bulgaria
Authors: Vasilev Aleksandar
Published: December 2022

Robots are introduced into a real-business-cycle setup augmented with a detailed government sector. Robots are modeled as an imperfect substitute for labor services. The model is calibrated to Bulgarian data for the period following the intro- duction of the currency board arrangement (1999-2020). The quantitative importance of the presence of robots in the economy is investigated for business cycle fluctuations in Bulgaria. In the presence of robots, wages increase, but employment falls after a technology shock. However, for plausible parameter values, the effect is predicted to be quite small.

Published: December 2022

На протяжении последних десяти лет в публичном поле идут активные дискуссии о проблеме домашнего насилия в России. В 2017 г. побои в отношении близких родственников были декриминализованы, а закон о семейно-бытовом насилии так и не был принят, хотя неоднократно вносился в Государственную думу. Цель настоящей статьи — анализ контрриторических стратегий, которыми пользуются участники дискуссии, отрицающие наличие или важность проблемы насилия между интимными партнерами. На основе анализа более 1,4 тыс. публикаций о проблеме домашнего насилия в девяти ведущих печатных СМИ России за период с 2010 по 2020 г. мы выделяем и описываем шесть стратегий депроблематизации в соответствии с классификацией, предложенной П. Ибаррой и Дж. Китсьюзом. Кроме того, мы выделяем не попадающую в классификацию седьмую стратегию, делающую акцент на материальной компенсации за насилие. Мы анализируем роль акцента на патриархальных ценностях в каждой из выделенных стратегий, а также делаем выводы об их возможной связи с общественными мнением о данной проблеме.

Published: December 2022

Diabetes mellitus, a chronic metabolic disease characterized by sustained hyperglycemia, has become a worldwide concern due to the upward trend of recorded cases each passing year. It is one of the leading causes of death in the world. Medication for the management and treatment of diabetes is neither affordable nor accessible in most parts of the Philippines thus raising the need for cost-effective alternatives. Plant extracts have long been used as a treatment for a variety of diseases. One of the plants to display biological activity is Hibiscus spp. It is used to treat a variety of diseases and has steadily gained recognition for its anti-diabetic properties. Several of its plant parts such as the leaves, flowers, and calyces had been used in laboratory models of type 1 and 2 diabetes mellitus. However, methods of extracting biologically active components of the plant vary and yield different results depending upon the concentration and temperature of the extraction procedure. Furthermore, it has shown hypoglycemic effects comparable to commonly used drugs in the treatment of diabetes such as metformin and glibenclamide. Although these studies suggest the efficacy of Hibiscus spp. extract as an antidiabetic agent, it still warrants further clinical trials to establish its efficacy and limitations.

Authors: MENDOZA TOLOSA HENRY ANTONIO , CAMPO ROBLEDO JACOBO ALBERTO , CLAVIJO CORTÉS PEDRO HUGO
Published: December 2022

En este capítulo se hace una evaluación de la tributación territorial de Colombia abordando diferentes ámbitos de impacto. En tal sentido, con el perfil del recaudo departamental y municipal se describe la representatividad que tienen los impuestos en la financiación del gasto público y se analiza la conformación de la canasta para el periodo 1990-2020, identificando los tributos que más contribuyen a ella. La eficiencia tributaria en este contexto se expresa desde la perspectiva del aporte que hacen los impuestos locales a la dinámica económica, el producto interno bruto nacional y local y las actividades gubernamentales en municipios y departamentos. El papel que cumplen los tributos en el escenario regional se complementa con la descripción del impacto que tienen en el contexto macroeconómico, tanto por su incidencia en la financiación total del gasto público como por su participación en la creación de riqueza en el concierto de los países de América Latina.

Published: December 2022

En América Latina, los problemas que afrontan los sistemas tributarios son comunes a todos los países: bajo recaudo, aumento de la brecha fiscal (mayor gasto y menor ingreso), desorganización y congestión administrativa, ineficiencia en la ejecución de los recursos y proliferación de tributos que hacen dispendiosa la gestión del recaudo.

Improving Insurance Operations in Nigeria Through the Digital Technologies
Authors: Adejumo Wahab Adewuyi , Tijani Adetunji Raimi
Published: December 2022

This paper aims to evaluate the impact of digitalization technologies on the insurance industry in Nigeria. Data were obtained from primary sources only. The primary data were collected through the mailed questionnaires that were administered to selected Chartered Insurers in Nigeria. The questionnaires were designed to reveal issues on digital transformation in Insurance industry in Nigeria. Seventy (70) questionnaires were sent to the respondents across the country in the six Geo-Political zones in Nigeria. It is noteworthy that 45% of the respondents were the Chief Executive Officers of different insurance companies, 30% of them were at Senior Manager Level of the Life Assurance Companies while the remaining 25% were the General Managers of Underwriting, Claims, Marketing and Human Resources Departments. It was found out that Nigerian Insurance companies as well as the NAICOM had transformed more than 40% of their services into digital technology. Besides, the research further revealed that almost every insurance company in Nigeria has a digital platform. The research recommends that the Federal Government should create sufficient budgetary allocation to invest in InsurTech and improve the training of the staff of the Government owned insurance companies such as NICON, Nigeria Reinsurance Corporation, LASACO, on the acquisition of digital skills. This will quickly encourage and mandate the private owned insurance companies to equally invest in InsurTech and arrange digital training for their staff so as to acquire digital skills necessary for the full digital transformation. The National Assembly should also amend the existing Constitutions on big data and recommend strict penalties for cybersecurity breaches. All these will disrupt the insurance services in Nigeria.
Discussing the Negative Impacts of Virtual Pilgrimage on Socio-Cultural & Religious Activities of Selected Asian Destinations during the Covid-19 Crisis, and the Need for Physical Presence

Published: December 2022

Pilgrimage tourism involves the physical traveling of pilgrims to a specific place of rituals. Pilgrimage as a distant journey has immense contributions to the sustainable development of tourism destinations until recently. The emergence of the Covid-19 crisis introduced some socio-cultural and religious changes through virtual pilgrimage (VP). VP is a type of pilgrimage that limits the physical presence of pilgrims to the place of rituals. Although VP reduces the spread of Covid-19 infections, it limits the sustainable development of socio-cultural benefits of biodiversity. For example, it reduces the aesthetic values of natural ecosystems and aboriginal relationships with the pilgrims. Previous studies on pilgrimage tourism have neglected the socio-cultural impacts of VP on tourism destinations during the Covid-19 crisis, preferring to focus instead on tourism development and types of pilgrimage. This emphasis could be critical if not well addressed. This study explored the negative impacts of VP on the socio-cultural dimensions of biodiversity and religious activities of selected pilgrimage destinations during the Covid-19 crisis using primary and secondary data. Findings from stage one suggested that VP introduces socio-cultural and economic changes such as a decrease in arrivals, pilgrim’s well-being, and job opportunities. Stage two analysis confirmed the findings. The study also discussed the limitations and future studies.
