Study Results

This article summarizes the concept of sharing, bibliographic analysis of publications in the field of car-sharing based on the Scopus database. The primary purpose of the study is to study the economic and legal basis for the development of car-sharing business models in Ukraine. Systematization of literature sources and approaches devoted to the economic efficiency of the implementation of car-sharing business models has shown that in Ukraine, this issue is almost not paid attention to in the economic, scientific sphere, and legal, scientific areas. The urgency of solving this scientific problem lies in the need and ability to relieve road traffic from traffic jams, reducing the average downtime of vehicles, as well as economic benefits for entities (vehicle owners and passengers) involved in sharing business models. The research has the following logical sequence: the types of car-sharing business models were analyzed, and their comparative characteristics were carried out; the economic and legal preconditions of car-sharing business development in Ukraine are investigated. The research identifies legislative obstacles to the establishment of a car-sharing company in Ukraine. A SWOT analysis of the conditions for implementing a car-sharing business model in Ukraine was performed. It analyses the costs and efficiency of creating a business based on a car-sharing business model in Ukraine on a conditional example. We propose to use system-structural and comparative analysis to analyze the problems of modern transport, methods of formal-logical analysis for determining the directions of development of car-sharing business models, and economic method for assessing the effect and a payback period of the proposed project car-sharing business model. The study results can be useful for the development of the car-sharing business in Ukraine, for entrepreneurs, scientists, and vehicle owners. Keywords: car-sharing, car-sharing business model, car-sharing business, motor transport, hire, expenses, analysis.

Supply Reliability

During the functioning of power supply system, there can be situations where the culprit in interruptions of power supply to consumers and a power quality violation is a power supply company or a consumer himself. Therefore, the economic incentive for power supply companies and consumers to increase power supply reliability and power quality is an urgent task. To implement such incentives, it is necessary to control the facts and time of power supply outages and their values as well as cases and time of non-compliance of power quality with the requirements of standards. It is possible with the use of a monitoring system for power supply reliability and power quality. (Research purpose) The research purpose is in developing a technical and economic method for stimulating power supply companies and consumers to increase efficiency of power supply system. (Materials and methods) The article provides a review of the structural diagram of a system for monitoring power supply reliability and power quality including devices for monitoring the number and duration of power outages and voltage deviations. (Results and discussion). An economic method has been developed to stimulate power supply companies and consumers to increase power supply system efficiency. The essence of the method is to control the parameters of power supply reliability and power quality, identify the violation of these parameters, determine the culprit of the violation, determine the time characteristics of the violation, summarize the duration of violations for the reporting period, compare the actual amount of duration with the allowable one, determine the amount of compensation for the violation and impose sanctions on payment compensation by the perpetrators of violations of these parameters. The article presents an algorithm for adjusting the cost of electricity supplied to consumers depending on the number and duration of voltage deviations and the number and duration of outages. The algorithm serves to ensure the operation of the specified technical and economic method. (Conclusions) The algorithm works in conjunction with a system for monitoring power supply reliability and power quality based on signals from devices that control the number and duration of outages and voltage deviations.

AbstractConflict between police, private security and political protesters is a topic that has been researched widely in criminology and other disciplines (e.g., Choudry 2019; Gilmore et al. 2019; Goyes and South 2017; Jackson et al. 2018; Rigakos 2002; South 1988; Weiss 1978). Adopting a green criminological lens, this article seeks to contribute to this rich body of research by examining police and private security responses to campaigning against opencast (open-pit) coal mining in Pont Valley, County Durham, United Kingdom (UK). Based on qualitative interviews, the article examines activists’ perceptions of responses to their campaign. Our findings reveal that rather than acting as neutral arbiters, police colluded with private interests, overlooking the abusive behavior of private security and bailiffs, particularly during the eviction of a protest camp at the proposed mining site. Activists believed that their right to protest was not respected, that their safety was jeopardized, and that police had willfully ignored a wildlife crime perpetrated by the mining company in order to enable mining to go ahead. Our article argues that the Pont Valley case fits into a wider pattern of repression of environmentalism in the UK, supporting Gilmore and colleagues’ (2019) argument that a progressive transformation in policing has been overstated.

Rice Paddy Soils

The goal of this study was to quantify the mobility and partitioning of trace elements originating from mine waste rocks derived from open pit coal extraction activities. The results showed that native rice plants were adapted to growing in metal contaminated soils, posing a severe health risk to local population. Sequential extraction procedures and bulk soil chemical analyses both suggest enrichment of Cd, Pb and Cu in rice paddy soils. Lead was shown to be evenly partitioned among all mineral and organic phases. Copper was associated with carbonates and organic matter. Smaller fractions of Pb and Cu were also bound to Fe and Mn oxides. Only 25% of Cd, 9% of Pb and 48% of Cu were associated with the exchangeable fraction, considered mobile and thus bioavailable for plant uptake. Effects of Cd, Cu and Pb on local Cam Pha Nep cai Hoa vang, and control Asia Italian rice, showed marked differences in growth. The local Vietnamese variety grew close to control values, even upon exposure to higher trace metal concentrations. Whereas the development of the control rice species was significantly affected by increasing trace metal concentrations. This result suggests toxic trace elements accumulation in the edible parts of crops.

Adaptive Neuro-Fuzzy Inference System has the merits of high convergence speed, potentially better generalization capability, high prediction accuracy and definiteness of the training results, and it has been applied to inverse design of slopes and surface displacement due to coal extraction. By training and checkout the collected 19 examples of mining under water body, the optimum ANFIS modeling was established. ANFIS-based approach for the forecast of the height of transmissive fractured belt are applied to the extraction the No.Ⅲ ore body at Kangjiawan Zinc-Lead Mine successfully, some important conclusions are of great significance to the factual issues. All the experiences may be of greatly beneficial reference for the similar projects since then.
