Authors: Abbasipayam Sadjad , Makrova Nataliya Vladislavovna
Published: January 2022

Energy consumption factors in the systems of cooling, heating, air conditioning and lighting in a building have a significant impact on the energy costs. Intelligent energy control methods help modernize the engineering systems of buildings, while using artificial neural networks and fuzzy logic for minimizing energy consumption is espe-cially effective in the operation of buildings. To control energy consumption there was proposed the Mamdani fuzzy inference system, selected membership functions of Gaussian, triangular and trapezoidal shapes in the course of the research, implemented the types and functions of inputs and outputs for engineering systems control subsystems in software. According to the input and output parameters, the following systems were designed: lighting, smart window, HVAC; fuzzy inference tables were built, graphical data analysis was performed. The proposed control solutions for the implementation of fuzzy rules based on linguistic variables make it possible to adapt the building management system to environmental conditions and prevent excessive energy consumption. The study substantiates the choice of energy-consuming parts of the building; when forming control actions, fuzzy logic rules are applied in functional ranges. The fuzzy inference system was shown to generate the solutions in accordance with changing input data, integrated control is implemented, the responses of lighting, heating, ventilation and air conditioning systems are analyzed depending on the input membership function. It is proposed to control the intensity of ambient light using motion sensors, including optical ones. It is shown that the results obtained make it possible to achieve a reduction in lighting energy consumption by 15 - 25%, maximum use of external light, ensuring a comfortable temperature regime, and also lead to implementing the coordinated and integrated control functions

Published: January 2022

The paper is focused on collecting and analyzing the data on the population density in the districts of

a megapolis was carried out. Each district is further divided into sections to improve the accuracy of the study. The analysis of data on the location of passenger public transport stops in residential areas and areas with socially significant objects was carried out. Visualization of the analysis results was performed by superimposing isochronous accessibility of the main objects of attracting passengers onto the map of the city. Using the algorithm of the minimum cstop of the way there have been found the points of destination in all the routes of the public transport network, which the passenger will be able to reach in 15 or 30 minutes. The route network is presented as a graph, whose vertices are public transport stops. The weights of the graph correspond to the travel time from one stop to another. The shortest paths between all vertices of the graph have been found. The Floyd-Warshell algorithm is selected for calculations. The obtained data are prepared for using them in the transport network model to solve a multi-criteria optimization problem. When adding a new vertex, it becomes possible to calculate a new route with minimal time cstops. Based on the results of the study, the initial data were prepared for constructing a model for generating data on the passenger traffic of urban land transport.

Authors: Usachev Yurii , Klochkova Irina
Published: January 2022

The article considers a mathematical model of a parachutist floating on the open parachute in the wind. The aim of the work is to study a system of differential equations describing the speed of the motion of the parachutist when descending on the open parachute, in order to establish the dependence of the trajectory of movement of the parachutist, the presence and stability of equilibrium states on the wind. Initially, a system of ordinary differential equations is considered, which determines the relationship between the acceleration of the parachutist and the speed along each of the three coordinates of space in windless weather. Then the influence of the wind is taken into account. The theorem on the number and stability of equilibrium states is proved. Numerical values of coefficients of the system of differential equations are obtained on the basis of real data received with the help of special software installed on the parachutist's mobile device by the method of nonlinear regression analysis. The equilibrium states of the jump, their stability and the maximum value of the speeds at the moment of landing with the presence of wind are determined. For the obtained system of ordinary differential equations, a theorem is proved on the magnitude of the skydiver's drift, the curvature and torsion of the trajectory depending on the wind.

Published: January 2022

The use of modern digital technologies during the industrial revolution enables to revise a number of approaches to the organization of technological processes, in particular when introducing approaches to the implementation of repair programs of energy enterprises. Through the example of the network planning and control system, the use of the overhaul activity schedule for generating equipment is considered, taking into account the logging of asbuilt documentation in a digital system, which is a software and technical complex made up of a centralized data storage system and a decentralized registry. The improvement of equipment, the development of diagnostic tools and methods directly affects the maintenance and repair system. In the maintenance system under development, it is planned to make a transition from statistical empirical assessments of the technical condition of equipment to objective ones based on automated technical diagnostics systems. On the basis of an algorithm for implementing a technical condition-based equipment repair program for energy enterprises, the authors proposed an algorithm for conducting technical supervision and recording the stages of work performed in a distributed register, based on the capabilities of modern digital data collection and processing systems. Obtaining parameter values for further use in the operation of the proposed algorithm is carried out on the basis of the capabilities existing at energy facilities of information-measuring and control systems. The use of the network planning and management system in the form of a network schedule and the algorithm proposed by the authors for conducting technical supervision and recording the stages of work performed during repair activities will make it possible to objectively determine the amount of labor resources necessary to perform the planned scope of work within the specified period, identify critical works delaying the completion of repair, actively manage repair by analyzing the progress of repair work and making reasonable organizational and technical decisions that ensure the performance of work within the planned time frame and at the lowest possible costs.

Authors: Kolosov M. V. , Lipovka Yu. L.
Published: January 2022

The goal is to create and test an algorithm for finding places for the optimal replacement of sections of the heating network of the district heating system to maintain the standard values of trouble-free operation with a minimum of financial costs.Methods. To carry out computer modeling, mathematical methods were used to calculate the flow distribution in branched and looped thermal-hydraulic circuits. A systemic model of the heating network with an indication of the parameters used in the construction of the function of minimum costs, and a method for determining the places of replacement of pipelines of the heating network to maintain the indicator of failure-free operation above the standard have been developed.Results. An algorithm is proposed to implement the principle of increasing the reliability of district heating networks through the development of a system model of a heating network. As a result of using the technique, a schedule for the optimal replacement of pipelines for the area under consideration over the next 30 years was obtained. It is shown that the proposed complex method of qualitative and quantitative assessment of the efficiency of district heating networks allows one to identify an indicator of failure-free operation, which may be higher than the standard for the entire period of time. It has been established that the optimal timing for replacing individual sections of heating networks is due to the variation of the input parameters of the heating network: the year of laying the pipelines of this system, the year for which the calculation is made, the diameter of the pipeline and its length, the type of pipeline laying and the area of its location, and the output parameters — the costs of maintaining system and the likelihood of system uptime.Conclusion. Based on the results obtained, a comprehensive method for assessing the cost of maintaining the operability of district heating networks is recommended. It is shown that the proposed method improves the quality of management decisions to ensure trouble-free operation of the heat supply system. In the future, it is planned to develop guidelines for the use of the proposed method in the development of a section of reliability and survivability of promising heat supply schemes for cities and towns.

Authors: Stepanenko M. N. , Martunov A. V. , Shelginsky A. Y.
Published: January 2022

The system analysis of the current state of quality of functioning of ventilation systems of industrial and public buildings in terms of volumes and modes of fuel and energy resources consumption has been carried out. The analysis of energy efficiency of using a steam-compression heat pump system for utilization of heat of ventilation emissions for heating the supply air has been carried out. Direct-flow ventilation systems with and without the heat pump unit are compared. A mathematical model and a calculation algorithm of the considered ventilation systems are offered. The model can calculate operation modes of one of the arrangement options both with fixed values of parameters affecting the result and with variables, which allows carrying out multivariate calculations and numerical research quickly and with minimum labour inputs. The results of comparative analysis are given on the example of a specific production room. Heat, moisture and air balance data obtained from regulatory documents and reference data, as well as the results of research by other authors are used as source data. Depending on the chosen arrangement, the contents of the calculations and the results obtained are different.In addition, the developed model allows, depending on the considered arrangement and the need, to obtain a large number of output parameters, such as surface areas of heat exchangers, heat transfer coefficients, all thermophysical properties of working media in all nodal points of the flowing process, etc. The principles of a comprehensive approach to assessing the efficiency of ventilation systems based on a system analysis, taking into account the parameters of heat and cold consumers, environmental parameters, the impact of aerodynamic characteristics of the air duct on energy costs and the tariff index in different climatic zones of Russia are substantiated.
Linguopragmatic Potential of Active Processes in Russian Neological Word Formation of Latest Period
Authors: Radbil T. B. , Jaszay L. , Palosi I.
Published: January 2022

The communicative-pragmatic effects in the generation and functioning of new phenomena in the Russian neological word formation of the latest period is discussed in the article. It informs about nonderivatives, created according to conventional and / or nonconventional models. It is shown that the specific intentions of the speaker and the addressee, their communicative needs, nontrivial topics of communication and the environment of speech, the features of the interaction of communicants, their communication strategies and tactics, etc. stand behind the formation of nonderivatives. Particular attention is paid to the following linguo-pragmatic mechanisms with the participation of nonderivatives: operations with semantic and pragmatic presuppositions, operations with inferences and implicatures of discourse, models for the implementation of conditions for the success of a speech act, the generation of indirect speech acts and speech reproduction of communicative strategies de dicto and de re use, contexts of using metalinguistic operators. The emphasis is made on the fact that the use of derivatives leads to semantic compression, the semantic capacity of the entire expression due to the actualization of various kinds of implicit information. The authors come to the conclusion that new formations in modern Russian speech testify to social attitudes, value priorities and speech-behavioral stereotypes of the speakers of the modern Russian language.
System of Subjective Deixis Means in B.L. Pasternak’s Early Prose
Authors: Soloveva S. A.
Published: January 2022

The means and methods of subjective deixis, participating in the organization of the forms of subjective-author's narration is analyzed in the article. Their role in the formation of text interpretation strategies is determined. The relevance of the problem is associated with the peculiarities of the research material — the texts of the early prose of B. L. Pasternak, the montage of which is manifested in the alternation of points of view, the nonlinearity of the structure. This complicates the process of the reader's interpretation. The use of methods of continuous sampling, descriptive, contextual and interpretive types of analysis made it possible to reveal the specifics of the linguistic means of subjective deixis, the system of deictic relations. The analysis showed that the absence of marked transitions between exegetical (third-person narration) and diegetic (first-person narration) narrators leads to the fact that the deictic functional is simultaneously assigned to a complex of linguistic means used within the framework of one utterance or text fragment. These are personal pronouns and discursive elements that activate the reader’s attention. Inconsistency in the use of forms of subjective-author’s narration leads to the formation of hybrid models. It reflects the process of the author’s search, an attempt to establish deictic parity (synchronicity of perception) between the author, character, reader and “observer”, forms new relations in the author-reader system.
Thematic Scientific Bibliography as a Discourse: Modern Youth Values
Authors: Eremina M. A.
Published: January 2022

The experience of collecting and systematizing scientific sources from different humanitarian fields, united by a common theme — values in the modern youth environment are described in the article. This content brings the article closer to the genre of an interdisciplinary bibliographic review. The practical task of the review is to prepare a bibliographic reference manual for publication. The selection of scientific publications was based on key axiological concepts, as well as on the idea of youth as a demographic and sociocultural group of people from 14 to 30 years old, on the way to becoming psychophysiological maturity and socialization. Conclusions of a theoretical nature are connected with the identification of general patterns of development of youth axiological issues: consideration of values within the framework of individual types (moral, political, religious, family, etc.); the predominance of works devoted to the study of the mutual influence of values and the sociocultural environment; the predominant interest of scientists in the study of spiritual, moral and socio-political values; the tendency of the last 5 years to highlight the values of communication and information as an independent object of axiological research. The practical task of compiling a bibliographic manual is solved in the form of determining the main principle of rubrication, which is the subject-thematic (typological) approach.
Baghdad Pact as Reflected in Turkish Weekly “Akis” (50s of XX Century)
Authors: Zhelobtsov F. F.
Published: January 2022

The article deals with the history of the Baghdad Pact — a kind of symbol of the “cold war” in the middle of the last century in the Middle East, which Turkey be-came an active promoter of. The author traces the development of events that caused a great resonance in society. It is shown that the growing protest mood found its response on the pages of the “Akis” weekly, the first neutral democratic print organ in Turkey, which officially did not belong to any political party. The relevance of the article is seen in the fact that the well-known modern changes in the Middle East policy of Turkey, aimed primarily at taking into account the national interests of the country, originate from regional events in the Middle East in the 50s of the last century. It is argued that the materials of “Akis” in a specific context, as a kind of lessons from the past, make it possible to understand and appreciate many of the nuances of modern difficult Arab-Turkish relations, the roots of which go back to events that were directly related to the Baghdad Pact.

Authors: Ivanov A. A. , Kuras S. L. , Kurаs T. L.
Published: January 2022

The article is devoted to the analysis of modern Russian historiography of criminal and political exile to Siberia. The authors consistently consider the main directions of development of post-Soviet studies, note, first of all, the great interest of historians in various aspects of the penitentiary policy and practice of the empire in Siberia, the features of the imprisonment of political and criminal prisoners. Further, a sharp drop in the attention of specialists to the history of the exile of the Social Democrats, and above all, the Bolsheviks, is stated, and vice versa — a significant increase in works devoted to the stay in exile of representatives of the Socialist Revolutionaries and anarchists. The publications on the history of the exile to Siberia of the Decembrists are analyzed, the content of the discussion about the evolution of their worldview, the role of “noble revolutionaries” in the political his-tory of Russia is conveyed. The authors also briefly analyze the main directions of publications of the Irkutsk collection of scientific articles “Siberian Link”, created back in 1973. It is concluded that the history of criminal and political exile to Siberia as a scientific direction in the post-Soviet period continues to develop successfully, acquiring new facets, replenished with specific studies and authors.
Autonomization of European Ultra-Peripheral Regions (XX—XXI Centuries)
Authors: Muslimova E. O.
Published: January 2022

The issue of the specifics of the “center — regions” relations of the European island regions (Faroe, Aland, Canary, Balearic, Azores, Sicily, Sardinia, Madeira), identified on the basis of ultra-peripheral criteria, is considered. Attention is paid to the formation of a belt of ultra-peripheral regions in the pan-European space. The results of a comparative analysis of the expanding stages of the autonomy of the studied territories are presented. The question is raised about the institutional and constitutional design of the special status of regions. Particular attention is paid to the achieved breadth of autonomous competencies and powers. The novelty of the study is seen in the formulation of the research problem from a new research perspective — the concept of ultraperipherality. The author dwells on the consideration of bilateral relations at several levels of political interaction: the ultraperiphery is the national “center”, the ultraperiphery regions are the EU. The relevance of the study is due to modern political and other processes taking place in the European Union under the influence, including the processes of autonomization of regions and their emergence to a new level of political influence. A classification of regions is proposed according to several criteria related to their autonomy and the acquisition of self-government. It is proved that the expansion of autonomy is one of the components of a special approach to the development of the region and the satisfaction of its needs.
Features of Social Structure of Adyghes (Shapsugs, Natukhais and Abadzekhs) in First Half of 19th Century
Authors: Tkhamokova I. Kh.
Published: January 2022

The question of the peculiarities of the social institutions of the Shapsugs, Natukhais and Abadzekhs — three groups of Circassians is considered. The relevance of the study is due to the fact that this problem is of interest for Caucasian studies and for solving theoretical problems of history and ethnography. The novelty of the work is seen in the use of archival documents, introduced into scientific circulation for the first time and in a new interpretation of already known sources. It is proved that some features of the social structure of these groups developed in those times when they lived in the mountains and had the opportunity not to submit to the power of the princes. It is shown that other features were the result of social conflicts at the end of the 18th — the first half of the 19th centuries. The question is raised about the reasons for the victory of the peasantry in these conflicts. It is noted that these include kinship and community solidarity, as well as the widespread distribution of firearms. Particular attention is paid to such social institutions of the Shapsugs, Natukhais and Abadzekhs as “brotherhoods” based on consanguinity and on the oath of mutual assistance. Their role in the consolidation of the peasantry and the strengthening of its influence is revealed. It is argued that thanks to the “brotherhoods” the number and territory of these three groups greatly expanded. The author also reveals the role of rural communities and their unions at different levels in the political system.
Liposomal bupivacaine provides longer duration analgesia than bupivacaine hydrochloride in an adjustable sole-pressure model of equine lameness
Authors: Moorman Valerie J. , Pezzanite Lynn M. , Griffenhagen Gregg M.
Published: January 2022

OBJECTIVE

To compare the efficacy and duration of action for perineural analgesia with liposomal bupivacaine (LB) versus bupivacaine hydrochloride (BHCl) in a sole-pressure induced model of forelimb lameness in horses.

ANIMALS

6 healthy adult research horses.

PROCEDURES

In 1 randomly assigned forelimb, grade 3/5 lameness was induced by use of a sole-pressure lameness model. Objective lameness (vector sum [VS]) was determined with an inertial sensor system at 0, 1, 6, and 24 hours after lameness induction to evaluate the model. Mechanical nociceptive thresholds (MNTs) and objective lameness (VS and force platform kinetics) were recorded prior to and at 1, 6, 24, 48, and 72 hours after perineural anesthesia of the palmar nerves at the level of the proximal sesamoid bones with LB or BHCl in random order, with a 1-week washout period between crossover treatments. Data analysis was performed with mixed-model ANOVA.

RESULTS

When evaluating the lameness model, there was a decrease in lameness at 24 hours in at least 1 limb of each horse (7/12 limbs); thus, screw length was increased by 1 to 2 mm at each 24-hour interval to maintain lameness. Compared with results at baseline, horses treated with BHCl had significant improvements in median MNT and VS identified at only 1 hour after injection, whereas treatment with LB yielded significantly improved median MNT, VS score, and peak vertical force for up to 24 hours.

DISCUSSION

In this experimental model of forelimb lameness, LB provided longer analgesia when compared with BHCl and should be further investigated for treatment of pain in horses.

The rate of diabetes has increased in proportion to that of obesity and thus is a topical issue that is carefully studied and for which various IT solutions are proposed to facilitate the treatment and monitoring of patients. There are many applications that can be used by those diagnosed with diabetes, those with various specifications useful in ensuring a healthy lifestyle, reminders for testing and nutritional journals. This paper highlights a brief analysis of existing applications for monitoring patients with diabetes and proposes a useful computer application in collaboration between the specialist, patient and laboratory physician. Many people do not have access to specialized medical services (especially those living in rural areas, in isolated areas) and at the same time, the current context of the pandemic proves the need for certain technological solutions for monitoring patients at home.
The impact of using emoji in online advertisements on consumer behavior. Case: Banking sector in Lebanon
Authors: Tarhini Bassam , Saikaly Sandy
Published: January 2022

Communication is an essential element in life. It is key to understanding each other, forming relationships, and sharing knowledge, information and ideas. “Social media is modifying the ways we communicate and is providing marketers with interactive means to effectively reach consumers. This has given rise to those digital images known as Emoji, which is a trending topic that is shaping our lives and sculpting its way to related social sciences.

Many businesses have been employing emoji in their communication messages, yet little research was conducted in this area. This research will build new insights and will investigate the role of emoji in influencing behaviors in terms of engagement, satisfaction, loyalty, and perception.

Abductive approach to theory was used. Secondary data was collected to explore and explain the concept of online marketing psychology using emoji language. The idea is then tested via survey, to modify the existing theory, and to generate a new idea regarding banks via interview as well.

Research questions investigated the use of emoji in online communication as an effective way to engage consumers, whether emoji lead to better customer satisfaction and loyalty, and how serious organizations can benefit from employing them to break the perceived “coldness”.

Results approved the effectiveness of emoji use in marketing, and they’re no longer limited to “modern” businesses, rather they’re starting to encompass almost all businesses in different industries. The research ends with a set of recommendations that’ll guide businesses through this trend.”

Published: January 2022

In the broad field of economic research, the process of resource allocation and the degree of manifestation of the freedom of the competitive market are relevant points of interest in order to achieve in terms of microeconomic performance. Through this work, we have proposed to investigate the extent to which competitive markets tend towards that form of perfection and what are the main challenges and implications for the market freedom. The novelty of this study counts in bringing to the forefront the match-making process, implicitly the study of the match-making market, introduced by the American economist Alvin E. Roth in 2015. In particular, it analyzes a new valence of the competitive market, the operating mechanism being aimed at highlighting a specific terminology, such as linguistic decryption of markets. This paper has extended the concept of matching, by analyzing the ethical issues involved, as well as the way in which we are witnessing a crescendo of concrete examples of the functioning of these markets. At the same time, we used the use of methodological tools specific to the analysis of statistical data on measuring the degree of competitive freedom in the main key sectors in Romania in 2015 and 2019, by applying The Aggregate Index of Competitive Pressure (AICP). The results showed the degree of openness to competition of the main sectors in Romania, as well as the fact that the matching market assumes the effective operation and manifestation of the competitive mechanism.

Understanding museum visitors’ behavioral patterns may help in predicting their number of visits. The aim of the research is to identify the trend models associated with the number of visitors, in 2012-2019, in 2 national museums in the top of the most visited museums in Romania: the National Museum of Natural History “Grigore Antipa” in Bucharest and the National Museum “Peles” in Sinaia and forecast the number of visitors to these objects in 2020 and 2021. Subsequently the same methods were used to analyze the total number of visitors to museums in Romania in 2012-2019 and to forecast the number of visitors for the years 2020 and 2021. The research method used was that of coefficients of variation, which aimed to determine the forecasts for the number of visitors through three types of models: linear, quadratic and exponential. However, Covid-19 pandemic dramatically changed the forecasts of visitor flows in the museums and the managers of these cultural heritage institutions had to cope with this situation.

Published: January 2022

Nowadays, employers are reconsidering the definitions of professionalism and professionals. In addition to job related knowledge and skills, a professional need some general behavioral skills too, which are especially required when working with others. These inter-relational skills are not “hard skills”, but “soft skills” Being challenge to face an economic reality that is changing permanently, universities have to adapt themselves and to respond to the needs of the socio-economic environment by developing and adapting their educational services to the contemporary requirements. Among the multiple dimensions of the changes universities are facing nowadays important ones are the changes at the curriculum level: goals consisting in competences according to the labor market requirements, new educational plans and programs, new content and teaching and learning strategies, new learning settings and environments. The paper presents the experts’ perspective in respect with the ways in which universities are developing and innovating their curricula and analyses Romanian employers’ opinions regarding the curriculum development and innovation in schools of economics and business. The analysis is based on a survey conducted among the most important employers in Bucharest, the capital city of Romania and, in the same time, the largest local labor market in the country with national and multinational companies. Recommendations regarding the curriculum development and innovation are included too. These are meant to enhance the capacities of universities to provide high quality education and develop competences required on the labor market.

Authors: Bulatnikov Vladimir , Constantin Cristinel
Published: January 2022

The paper discusses the key features of the state of the structure of healthcare in Russia and Romania, the administration of this scheme is assessed and the statistical array takes place over a long period. The health sector’s sustainable status is perceived to be the main target concern of each state. The medical care degree is the country-wide coefficient of well-being. However, not only at the state level, but also at the regional level, the characteristic effect of socio-economic factors on population health metrics is especially pronounced. Without the introduction of modern approaches to management, it’s more professionalization, that is, the building of a management organization that insists on the professionalism of leadership, the solution to the problems of healthcare growth is unlikely. One of the essential national tasks of establishing a plan for the socio-economic growth of Russian and Romanian healthcare and raising the standard and quality of life of the people is to strengthen the healthcare system. The provision and management of the quality of patient services can be considered one of the most significant concerns in the area of healthcare. Moreover, these issues are the most difficult to address, which is why, during a time of economic and social turmoil, their importance grows significantly.
Resource abundance as an indicator of economic development in selected countries
Authors: Hodor Mădălina Andreea , Clodnitchi Roxana
Published: January 2022

The efficiency of resources is a current issue that can be of great interest to anyone, especially since it is often associated with economic performance, at both - micro and macro level. Therefore, it can be useful to evaluate the resource availability of countries and to understand how a country’s economic development is connected with its resource abundance. Our study examines whether the availability of resources can be viewed as an indicator of the economic development of a particular country by analysing the correlation between the total resources rent, as calculated by the World Bank, and the gross domestic product and its development in 45 countries worldwide. We found that natural resources rents are linked to both GDP per capita and GDP growth, leading often to strong positive or negative correlations. The particular cases need to be further addressed, by looking into additional parameters on country and regional level.
One for the road: the determinants of the road fatalities in the European Union
Authors: Prada Elena-Maria
Published: January 2022

Traffic fatalities are a severe problem. The European Commission estimated that one in four road accidents are related to alcohol consumption. It is also shown that alcohol changes perceptions and is reflected in the driver’s reflexes. This study aims to determine the factors that lead to changes in the mortality rate due to car accidents. The dataset was retrieved from different official sources depending on the type of variable. For the time-invariant variables were used two official sources from which the drivers are informed with the main road rules from a certain country. Using the Arellano-Bover / Blundell-Bond linear dynamic panel-data estimation on 22 European Union countries between 2012 to 2018, the results showed that the road safety laws have a meaningful and significant impact on road fatalities. Alcohol legal limit has a positive impact on road fatalities, which shows that if the legal alcohol limit is non-zero, the road fatalities increase. Another important result is related to young people neither in employment nor in education and training (NEET), which directly influences road fatalities. This result shows the importance of investment in education. At the same time, the results underline the importance of investments in infrastructure, as the length of the highways increases leads to a decrease in road fatalities.

Published: January 2022

Machine Learning is a constantly growing area which has the capacity to analyze massive amounts of data and find relevant patterns, a very important feature in the era of big data. It has a wide range of application areas, including the financial field, and proved to be efficient in solving various problems, including the prediction of the default probability of a customer to meet their obligations to the bank, using classification algorithms. Their output is further used when deciding whether to approve a loan or no, based on the previous behavior of the customers, hence reduces the loss of the bank. Even though Machine Learning algorithms proved to be efficient in solutioning this type of problems, none was identified for remarkable results. This paper studies 10 different methods applied on the same dataset (Logistic Regression, K-Nearest Neighbor, Support Vector Machine, Kernel Support Vector Machine, Naïve Bayes, Decision Tree, Random Forest, Bagging Classifier, Linear Discriminant Analysis, Neural Network - Multi Layer Perceptron) and performs a comparative analysis aiming to identify the one which outperforms the others. Their performance is evaluated based on some well-known statistical measures such as Accuracy, Misclassification Rate, Precision and Specificity. In addition, this paper also presents and evaluates the impact of feature selection on the overall performance of an algorithm.

Authors: Barna Laura-Eugenia-Lavinia , Igna Roxana Dana
Published: January 2022

In this paper, I examined how the adoption and implementation of Enterprise Resource Planning systems influences an organization’s performance. Performance is a key component that underlies the organization’s activity. Enterprise Resource Planning systems are used to manage the activities of an organization (accounting, procurement, compliance, production, project management and other distribution chain operations). The impact of implementing Enterprise Resource Planning systems may differ from organization to organization. The main purpose of the paper is to present the most important performance indicators that are influenced by the implementation of Enterprise Resource Planning systems, but also what is their impact on the entire activity of an organization. The research method used is a quantitative research based on the questionnaire where we identified how Enterprise Resource Planning systems influence the performance of the organization. The data collected were useful to answer the main research questions formulated in the paper. The results obtained based on the questionnaire showed that organizations that implemented Enterprise Resource Planning systems obtained more favorable values of performance indicators than organizations that did not implement them. These Enterprise Resource Planning systems also have a role in the sustainable development of the organization, but in principle Enterprise Resource Planning systems are useful to improve the performance of the organization.
Taxing the digital economy – rethinking Romania’s prospects
Authors: Smedoiu Popoviciu Alexandra , Horobet Alexandra , Belascu Lucian
Published: January 2022

The digital revolution is fundamentally changing business strategies, structures and evolution, consumer behaviour and regulatory approaches. More than ever, the current pandemic has intensified the role of the ICT sector for economic and social survival and resilience and profiled it as a “winner” when compared to other sectors and industries. The paper addresses how the digital economy can contribute more in Romania from taxation, building on arguments in the literature in favour of considering the tax system composition as important as the absolute level of taxation. We discuss how the European Commission’s proposal of a digital services tax could be applied to Romania and what the impact would be on the ICT sector, which already benefited from certain tax advantages in the last 10 years. Within an exploratory and descriptive case study, we show the very good performance of the Romanian ICT sector relative to the overall economy in the last decade, in terms of turnover evolution and profitability, although its share in GDP remains relatively low. Still, average salaries in the industry are double than those of the overall economy, which may be an indication that its value added is higher. We conclude that it is unlikely for the Romanian ICT sector to be able to bear in full the EU proposed digital services tax, but a more bearable scenario is one with a 0.5% tax or 1% tax. Nevertheless, such a proposal should be accompanied by a comprehensive ICT strategy aimed at addressing the labour force competition and investing on the digitalization of the overall economy.
Online - education on YouTube before and after COVID 19. An example study on “Fun Science Romania”
Authors: Stoica Andreea Mihaela , Veith Cristina , Necula Marian , Marinescu Paul
Published: January 2022

The article aims to analyze how the public interest of an educational franchise has evolved and how it has been influenced by the pandemic. It compares the evolution of the traffic on the franchise’s YouTube channel, Profesorii Trasniti (Nutty Scientists), from two periods of time, “pre” and “post” pandemic, March 2020 being the calendar date taken as a benchmark.

The research methodology includes both a secondary analysis (based on articles published in the literature on topics such as: digitization, education in the virtual environment, social media as a tool in the equation) and a statistical measure of the difference between the proportions of the number of comments on published videos on the YouTube channel “Profesorii Trasniti” (Nutty Scientists) of the Fun Science Romania franchise, “pre” and “post” pandemic based on the data provided by the YouTube Analytics platform.

The questions that arise from this study are:

To what extent has the social media engagement of the “post” pandemic audience on the YouTube channel Profesorii Trasniti (Nutty Scientists) of the Fun Science Romania franchise increased in terms of its educational content?

To what extent has the interest in a strong educational content increased on YouTube compared to the one focused more on entertainment in the pandemic context caused by COVID 19?
Changes and challenges in telecommuting explained through multi-level perspective on socio technical transition

Published: January 2022

COVID-19 was responsible for a global health crisis beginning in early 2020 that saw telecommuting become commonplace regardless of the size of the firm, the sector or country. It’s possible that even before pandemics, there were some differences in the practice of telecommuting among countries and sectors. These differences were impacted by factors such as the cultural context and labor policies at governmental and corporate levels. Telecommuting in the EU had only reached 5.4% in 2019 before the Covid-19 outbreak, making it a relatively new trend when compared to the technological potential it offers. 40 percent of EU workers are expected to telecommute in 2020, in the early stages of the outbreak, according to estimates. This research uses the theory of socio-technical transitions (MLP) to examine how and why telecommuting suddenly became the norm among managers and workers from a variety of different industries. At landscape level, an opening was provided by the Covid-19 epidemic that allowed telecommuting to break over the niche-regime barrier.
Rethinking leadership models after COVID-19
Authors: Abramiuc Todoran Teodora , Popa Raluca Andreea
Published: January 2022

Leadership models in the times of COVID-19 is surely the topic of the hour, yet this hour might last for some few years. By the end of it, we will reach the point of no return and a new set of rules and paradigms would have been created. Many researchers and leadership representatives investigate this topic. The available and reviewed literature is rather shaping the discrepancies of the past-embedded practices, as opposed to the current challenges. In this context of constant change, the current paper is aiming to investigate some current leadership practices, which are targeting the level of productivity, different ways of working and communicating in the work from home context. Moreover, the research would be setting the stage for something that is not there yet, in the current leadership patterns. The research methodology based on top management and senior leaders’ interviews, covering multiple industries from Romania, like banking, energy, manufacturing at large scale and outsourcing. The questions were designed to investigate the realities on their new job definition, from a personal perspective, as people managers and the business value outcomes envisioned in the new scheme of work. The theoretical contribution of the paper is to define a set of guidelines and filtering areas of leadership focus. The set of information gathered for new business metrics of performance, the ownership, efficiency and business value creation is pushed at all levels. One major change is the new definition of discipline, shifting from authority into entrepreneurial attitudes.
Entrepreneurship in the Digital and Industry 4.0 Age: A semi-systematic literature review
Authors: Biclesanu Isabelle , Dima Alina
Published: January 2022

Industry 4.0 and digitalization are changing the business world. While companies are optimizing their processes and adapting to the new market conditions, some entrepreneurs are pushing the boundaries by creating new organizations that are capitalizing on the digital environment or even building the technologies behind it, achieving fast, impressive results. The paper is concerned with characterizing the Romanian entrepreneurship within the digitalization and Industry 4.0 context, through the means of a semi-systematic literature review of articles and conference proceedings published within last five years, indexed in the Thomson Reuters Web of Science (WoS) Core Collection database. Manual filtering, categorization and synthesis of the relevant articles were used along with co-occurrence networks built in VOSviewer. The main directions were discovered to be in six areas on the use of technology in business and two areas which were also particularly related to entrepreneurship education.
