Social Sphere of Kiselevo on Eve of Gaining City Status (Local Periodicals)
Authors: Karpinets A. Yu. 
Published: January 2023

The article is devoted to the development of the Kiselevsk village in 1935, the last year when Kiselevsk existed in the status of a workers’ settlement. The issue of improving the living and communal conditions of the miners of the Kiselevsky mine and their families is being considered. Attention is paid to the problems of the relationship between the material well-being of workers and the increase in labor productivity. The problems of housing and communal services, the development of the branches of upbringing, education and health care are characterized. The methods of ensuring the food security of miners are determined. Specific measures to improve the quality of life of workers in the context of the transformation of the settlement from a working settlement into a city are demonstrated. The novelty of the study is seen in the fact that for the first time, based on the processing of materials from the periodical press, the social sphere of the Kiselyovsky mine was characterized in detail in the mid-1930s. The relevance of the study is due to its scientific and social significance. The first is determined by the fact that this kind of research is undertaken for the first time. The second is connected with the need to draw attention to the problems of sustainable socio-economic development of the city of Kiselevsk at the present time.
Fair Trade in a Nomadic Society (in Kalmyk Steppe in Second Half of 19th — Early 20th Centuries)
Authors: Lidzhieva I. V. 
Published: January 2023

The issues of organization and functioning of fair trade in a nomadic society are studied on the example of the Kalmyk steppe in the second half of the 19th — early 20th centuries. The source base was documentary materials from the funds of the State Archives of the Astrakhan Region and the National Archives of the Republic of Kalmykia, revealing the record keeping practice of the Kalmyk People’s Administration and ulus departments on the organization of fair events in the steppe. The author, based on the historical and geographical approach, focuses on the vastness of the land and the dominant nomadic type of management in the Kalmyk society. It has been established that fairs not only played an important role in satisfying the commodity needs of nomads, which was important in the absence of goods for manufacturing and industrial production and agriculture, but also were a way for nomads to communicate with each other and with representatives of the foreign administration. Despite the importance of fair trade among the nomadic people, the process of establishing and functioning of fairs was associated not only with natural and climatic conditions, but also with the unwillingness of the authorities of neighboring provinces to create competitors.
Life and Nutrition of Pupils of Charitable Institutions for Children in St. Petersburg in Middle of 19th — Early 20th Centuries
Authors: Sinova I. V. 
Published: January 2023

The issues of organizing the life of children in charitable institutions of St. Petersburg in the middle of the 19th — early 20th centuries are considered. The study was carried out on the material of archival documents. Most of the sources are introduced into scientific circulation for the first time. The forms and methods of solving the issues of improving the conditions of hygiene, life and nutrition of pupils are revealed. The problem areas in the organization of the activities of institutions are characterized. The debatable issues that arose in the boards of trustees of institutions are listed. It is concluded that in the second half of the 19th — early 20th centuries, the requirements for the activities of charitable institutions increased. In particular, approaches to the provision of medical care have changed: it was envisaged to include doctors in the boards of trustees of shelters who provided assistance to pupils on a gratuitous basis, controlled the quality of food and monitored living conditions. The collegial nature of the activities of the St. Petersburg Council contributed to the success of solving the problems facing orphanages. The Council in its activities took into account the opinion of the public, doctors, teachers on the upbringing and maintenance of pupils. The shelters had different financial opportunities, which depended both on the composition of the Boards of Trustees and on the activity of its members in holding charitable fundraising events. However, during the XIX — early XX centuries, general requirements for the operation of shelters were formed.

Abstract
Power grid data asset management, maintaining the health and integrity of physical assets, optimising the allocation of physical assets, dynamically monitoring the distribution and operation of physical assets, and predicting the investment scale of operation and maintenance and technological transformation are important issues faced by power grid companies. First, the existing literature in this paper is sorted out to define the concept and characteristics of data assets. Then, a training model based on a knowledge graph and data asset relationship model is proposed. At the same time, the key technologies of the Industrial Internet of Things and the theoretical model framework of power grid technology are proposed, including device access, protocol conversion, edge data processing, connectivity, the first entry of data and the rapid growth of data volume. Finally, experiments are carried out to verify the framework proposed in this paper. Experiments show that the research on industrial Internet of Things and power grid technology based on knowledge graphs and data asset relationship model is of great significance for enterprises to exert data value and promote the development of the digital economy.
Prediction of Earth Rotation Parameters with the Use of Rapid Products from IGS, Code and GFZ Data Centres Using Arima and Kriging – A Comparison
Authors: Michalczak Maciej , Ligas Marcin , Kudrys Jacek 
Published: January 2023

Abstract
Real-time prediction of Earth Orientation Parameters is necessary for many advanced geodetic and astronomical tasks including positioning and navigation on Earth and in space. Earth Rotation Parameters (ERP) are a subset of EOP, consisting of coordinates of the Earth’s pole (PMx, PMy) and UT1-UTC (or Length of Day – LOD). This paper presents the ultra-short-term (up to 15 days into the future) and short-term (up to 30 days into the future) ERP prediction using geostatistical method of ordinary kriging and autoregressive integrated moving average (ARIMA) model. This contribution uses rapid GNSS products EOP 14 12h from IGS, CODE and GFZ and also IERS final products – IERS EOP 14 C04 12h (IAU2000A). The results indicate that the accuracy of ARIMA prediction for each ERP is better for ultra-short prediction. The maximum differences between methods for first few days of 15-day predictions are around 0.32 mas (PMx), 0.23 mas (PMy) and 0.004 ms (LOD) in favour of ARIMA model. The maximum differences of Mean Absolute Prediction Errors (MAPEs) on the last few days of 30-day predictions are 1.91 mas (PMx), 0.30 mas (PMy) and 0.026 ms (LOD) with advantage to kriging method. For all ERPs the differences of MAPEs for time series from various analysis centres are not significant and vary up to maximum value of around 0.05 mas (PMx), 0.04 mas (PMy) and 0.005 ms (LOD).
Microstructure and mechanical properties of selective laser melted 18Ni300 steel
Authors: Liang Yan , Qing Luo , Yu He , Huili Zhao , Yuxin Wang 
Published: January 2023

Abstract
The energy transfer process of selective laser melting (SLM) is highly complex. In this work, experiments were carried out to study the effects of SLM on the microstructure and mechanical properties of 18Ni300 martensitic steel. With the increase in laser power, the grain size of the cladding layer decreases and the microstructure becomes dense. The side hardness is higher than upper surface hardness, and the tensile strength and elongation both increase first and then decrease. When the laser power is 300 W and the scanning speed is 1,000 mm/s, the comprehensive mechanical properties are the best, as the tensile strength, microhardness, elongation at break, and elongation after fracture are 1,217 MPa, 37.5%, 37.6%, and 8.93%, respectively. EBSD (Electron Backscatter Diffraction) shows that columnar crystals grow along the growth direction (z direction) in XOZ and YOZ planes, and the grains show weak texture. There are many small-angle grain boundaries, and the grain sizes are <10 μm.

Published: January 2023

Abstract
In this work, a synthesis to improve surface wetting resistance composites via infusion of graphene (G) structure into the polyvinylidene fluoride (PVDF) matrices is introduced. Graphene is incorporated into the PVDF matrix with a percentage of 1.0 wt.% up to 2.5 wt.% using simple solvent blending and dry-casting methods. The morphological and structural properties of the graphene infused into PVDF are investigated using a variety of characterization techniques, including field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDX), and Raman spectroscopy. The tensile properties of graphene infused into the PVDF matrix are investigated using the INSTRON Universal test. The need for hydrophobicity performance on polyvinylidene fluoride infused graphene (PVDF/G) composite is also reported. Based on our evaluation, we ascertain that the PVDF/G-1.5% produces extremely high values for ultimate tensile stress and Young's modulus, amounting, respectively, to 90.24 MPa and 5720.88 MPa. The PVDF/G composite exhibits surface roughness and increases water contact angle (CA) by 20° more than pure PVDF. Therefore, it is possible to deploy PVDF/G composite thin films with suitable mechanical strength and hydrophobicity in biomedical material-based engineering applications.
Influence of air plasma spraying process parameters on the thermal barrier coating deposited with micro- and nanopowders
Authors: Kubaszek Tadeusz , Góral Marek , Pędrak Paweł 
Published: January 2023

Abstract
This study investigates the optimal conditions to deposit a thermal barrier coating using micro- and nanopowders in the air plasma spraying (APS) process. The influence of the APS process parameters on the thickness, porosity and hardness of the yttria-stabilized zirconia (YSZ; ZrO2 × 8Y2O3) coatings deposited with a single-electrode plasma gun was determined. The temperature and velocity of melted particles were determined by the DPV diagnostic system to decrease the number of experimental processes. The current and H2 flow rate were changed in this research. Metco-6700 YSZ micropowder has already been used in plasma spray physical vapor deposition. The results of this study suggest the possibility of using it for APS. The particles of this powder are characterized by high temperature (2,700°C–2,900°C) and high speed (>380 m/s). The highest thickness of the coating was obtained with 6 NLPM (normal liter per minute) H2 flow and 800 A current. Difficulties were observed with the feeding of the powder particles at higher H2 flow. The results showed that using APS, deposition of Metco-6609, a nanopowder normally used in suspension plasma spraying, is possible. In this research, this powder was fed using a carrier gas. The coatings were around 40 μm thick and had high porosity. The lowest porosity of the coating was obtained at a current of 600 A and H2 flow rate of 12 NLPM. In the coatings, unmelted spherical particles were also visible.
FDI and Economic Growth: A new Look from the Sectoral Perspective
Authors: Šimić Vladimir , Malešević-Perović Lena 
Published: January 2023

Abstract
This paper investigates the impact of foreign direct investment (FDI) on economic growth in a sample of 10 ex-socialist European and Asian countries. While the link between FDI and economic growth has been extensively investigated in empirical literature, this paper contributes to this literature by econometrically investigating the effects of FDI inflows in specific sectors using the panel data estimation techniques. In addition to confirming the positive impact of total FDI inflows on economic growth, using the WiiW (the Vienna Institute for International Economic Studies) FDI database, which disentangles the FDI data across different industries, the paper finds significant effects of FDI inflows in manufacturing on growth, whereas FDI inflows in other sectors are only sporadically statistically significant. This finding serves as a basis for further investigation of the specific subsectors (NACE 2-letter classification) within manufacturing, and the empirical investigation finds that not all FDI inflows within manufacturing enhance economic growth.
Sales Process as a Service (SPAS): Development and Validation of an Extension to the Shortened Selling Orientation – Customer Orientation (SOCO) Score (SOCO-SPAS)
Authors: Ledinger Stefan 
Published: January 2023

Abstract
The association between selling orientation and customer orientation and sales success has been a matter of intensive research since the publication of the selling orientation-customer orientation (SOCO) score in the early 1980’s. However, which attitudes predispose salespeople for high perfor-mance remains elusive. In addition, the association between customer orientation may be curvilinear and depend on the selling situation – and little research has been devoted to business-to-business (B2B) sales. This paper aims at starting to close those knowledge gaps through the development of a self-assessment tool for attitudes of salespeople. An extension of the 10-item SOCO score is developed through literature research in sales/business development and on service orientation in other settings. The score was subsequently validated through feedback by sales scholars. The extended score adds a dimension that tests whether professional salespeople consider the sales process as a service (SPAS) that should provide value beyond the identification of the best offering. Response rates by sales scholars was low, resulting in the need for further validation of the candidate SOCO-SPAS score. Business-to-business (B2B) relationships are an essential but understudied area of economics. The current paper provides a means to assess the relationship between attitudes and sales performance in modern B2B sales, by extending a scoring system that has originally been developed for B2C sales and many years in the past when market conditions were different than today.
Youth Entrepreneurship Among Higher Education Students – A Qualitative Research of Entrepreneurial Intention and Education
Authors: Mendonça Pedro , Braga Vítor , Ferreira Marisa R. , Braga Alexandra , Carvalho Amélia 
Published: January 2023

Abstract
The area of entrepreneurship education is developing rapidly, potentially conveying positive effects to business education, innovation and economies. Our paper seeks to analyse the entrepreneurial intention of a group of higher education students, and the data includes 29 interviews, administered to students of Portuguese higher education institutions. The results obtained allowed to confirm some of the aspects described in the literature, although a few divergences were also found. It was also possible to clarify some of the theories associated with barriers to entrepreneurship. The main limitations are related with the sample size, opening space for future research with larger samples. The most important implications relate to the identified need for very specific topics in entrepreneurship education. However, the key contribution of the paper also lies in its qualitative research approach.
The Impact of Women’s Economic Empowerment on the Rise of Female Entrepreneurship in Namibia

Published: January 2023

Abstract
In this paper the authors investigate the importance of women’s economic empowerment and its impact on the rise of female entrepreneurship and human capital in Namibia. The research includes a case study analysis with four in-depth expert interviews. Data triangulation ensure the study’s validity, and the case was examined through pattern matching. The results demonstrate that female entrepreneurs face challenges such as access to resources and education, socio-cultural norms, a lack of social protection, and a large and unprotected informal sector. The government and institutions shall promote women’s empowerment through a direct labour market intervention, support for the informal sector, a gender-sensitive constitutional, legal, and institutional framework, the enforcement and oversight of gender-responsive laws and policies, and access to resources and education. Furthermore, women require digital inclusion, entrepreneur networks, social protection, and reformed socio-cultural norms. If female entrepreneurs are empowered adequately, they will contribute to nations’ human capital, economic growth, and development.

Published: January 2023

Abstract
Destination image influences the tourist decision-making process, and their intention to visit, revisit and recommend. Therefore, a positive destination image is considered one of the key destination success factors. Tourists will form the image according to their own or others’ experiences and information related to the destination, one option to provide destination information is one of the most effective promotional tools called celebrity endorsement. With the assumption that a positive celebrity image will be transferred to the destination, this study will explore the effect of celebrity endorsement on destination image. The study aims to test the celebrity endorsement effect on destination image through the source attractiveness model, source credibility model, and the Match-up model. Data were collected using the online survey technique, the sample size was 204 respondents. Research hypotheses were tested by regression analysis. Results indicated that celebrity attractiveness, trustworthiness, expertise, and match-up impact the destination image. The theoretical contribution is reflected in new information regarding the role of celebrity endorsement in tourism, which is limited in foreign and domestic scientific literature. As a practical contribution, the study provides information that may be useful to tourism service providers in creating a promotional campaign.
Real-estate price prediction with deep neural network and principal component analysis
Authors: Mostofi Fatemeh , Toğan Vedat , Başağa Hasan Basri 
Published: January 2023

Abstract
Despite the wide application of deep neural networks (DNN) models, their application over small-sized real-estate price prediction is limited due to the reduced prediction accuracy and the high-dimensionality of the dataset. This study motivates small-sized real-estate agencies to take DNN-driven decisions using the available local dataset. To improve the high-dimensionality of real-estate price datasets and thus enhance the price-prediction accuracy of a DNN model, this paper adopts principal component analysis (PCA). The PCA benefits in improving the prediction accuracy of a DNN model are threefold: dimensionality reduction, dataset transformation and localisation of influential price features. The results indicate that, through the PCA-DNN model, the transformed dataset achieves higher accuracy (90%–95%) and better generalisation ability compared with other benchmark price predictors. The spatial and building age proved to have the most impact in determining the overall real-estate price. The application of PCA not only reduces the high-dimensionality of the dataset but also enhances the quality of the encoded feature attributes. The model is beneficial in real-estate and construction applications, where the absence of medium and big datasets decreases the price-prediction accuracy.
