Published: May 2022

This study examines the relationship between skill acquisition and entrepreneur development. Skill is the ability to acquire practical knowledge in new conditions and on the basis of the abilities and experiences a person had previously. It is an activity which is developed by a person with time and becomes automatic in terms of performing the required skill, while entrepreneurship development is a process of enhancing the skill set and knowledge of entrepreneurs regarding the development, management and organization of a business venture while keeping in mind the risks associated with it. This paper after a critical review of the available literature revealed a significant relationship between skill acquisition and entrepreneur development. The paper however recommend that; prospective entrepreneurs should ensure that necessary skills armed at enhance their businesses are acquired before venturing into their choice businesses; there should be a thorough knowledge of the pros and cons of business by prospective entrepreneurs before committing their financial resources and time on the business this is in order to avoid business failure; government at all levels should endeavour to promote small scale businesses by setting policies aimed at providing soft loans to intending persons this is in order to enhance speedy economic growth and that government should set up policies requesting multinational oil companies to support prospective entrepreneurs financially and materially in their communities of operation as part of their corporate social responsibility.

The deadly and infectious COVID-19 respiratory disease has brought in its wake untold uncertainties on the business environment globally. The impact of this fatal pandemic has shocked the transactions of businesses and service providers, including auditing firms to the core. This paper, therefore, explored the safeguards adopted by the auditor to mitigate the impact of the pandemic on audit quality. An online survey was used to administer questionnaires to solicit 289 valid responses from partners and staff of auditing firms in Ghana using a purposive sampling technique. Partial Least Square – Structural Equation Model (PLS-SEM) approach was adopted in assessing the measurement and structural models. The outcome of the study proves that the auditor’s instituted safeguards significantly moderate the impact of the COVID-19 pandemic on audit quality. This study provides ample contributions to regulators in the auditing profession to appreciate the impact of the ills of the pandemic on audit quality that forms the basis of informed economic decisions by users of financial reports. The researchers suggest that auditors should apply the appropriate safeguards to anticipated challenges emanating from the pandemic on their practices to express a better opinion on assurance and non-assurance services rendered for clients.

Diethylnitrosamine (DEN) is a metabolic product of various foods and beverages in which there are preservatives in the form of nitrate and nitrite. Nitrosamines are found in various products such as alcoholic beverages, processed meats, cigarettes, and cosmetic products. DEN is toxic and carcinogenic to organs such as the liver, lungs, kidneys, skin, stomach, and blood. In addition to giving DEN compounds, there are also CCl4 compounds as tumor promoter agents known as genotoxic substances that can increase the risk of genetic errors and stimulate cells to become malignant neoplasms. Administration of DEN and CCl4 induction can damage various organs of the body, one of which is the kidney. In a healthy body, angiogenesis plays a role in wound healing and the formation of new tissue. However, angiogenesis also contributes to carcinogenesis or the uncontrolled growth of cancer cells, and is malignant when the body is contaminated with toxic substances. Therefore, to determine the effect of the administration of DEN and CCl4 observations were made using the immunohistochemical method, to see differences in the histology of the kidneys of experimental animals, the positive control group, and the negative control group based on the VEGF angiogenesis factor. From these results, there are significant differences. In the negative group, there was no necrosis and high-value VEGF expression, but in the positive group, there was necrosis and a decrease in the value of VEGF expression compared to the negative control group.

Published: May 2022

Data on daily stock quotations of 216 Russian companies for the period from 2004 to 2021 are considered. The subject of the study is the law of distribution of the logarithmic profitability of shares. Out of the total number of companies, a part of the companies is left for the subsequent testing of the model. For each of the remaining companies, using the methods of the Python language, a law is selected (out of 40 available candidates), in the "best" way (in the sense of the KulbackLeibler distance), approximating the law of sample distribution. One of the most frequently appearing as the "best" is the generalized normal law (gennorm). The law has heavier tails compared to the normal one, and is given by three parameters (shape, position and scale). For 178 samples (remaining after removal of outliers) a regression model is constructed for the dependences of the parameters of the generalized normal distribution law on the first four initial moments estimated from the sample. Graphical tools have shown a good approximation of the empirical and hypothetical laws of profitability distribution. The goodness of fit rejected the hypothesis of the consent of laws at the 5% level for two companies out of nine. For seven companies, the goodness of fit showed that there were no grounds for rejecting the hypothesis of consent at the 20% level.

The possibilities of using mathematical tools to find the optimal solution to a formalized economic (control) problem are analyzed depending on the chosen optimization criterion and taking into account restrictions on the controlled parameters. It is noted that tasks that are completely different in terms of their goals, from the point of view of mathematics, assume a fairly standard solution scheme, the first stage of which consists in formalizing the problem and discussing the existence and uniqueness of the solution. We are talking not only about the problem of finding the best solution, but also about the possibility of forecasting in order to change the control parameters. It is shown how the optimization problem is reduced to finding the extremum of the objective function or even the objective functional. If there are no restrictions during formalization, then this will be the problem of finding an unconditional extremum; if the restrictions are given by a system of equalities, then this will be the problem of finding a conditional extremum; if the restrictions are given by a system of inequalities, then this will be the problem of finding a global extremum. The described mathematical toolkit is considered in more detail for two important problems of the economy – optimal resource management and optimal distribution of investments.

Published: May 2022

Сотрудники уголовно-исполнительной системы Российской Федерации осуществляют возложенные на них федеральным законодательством полномочия, направленные на обеспечение исполнения наказаний. К таким полномочиям следует относить и участие сотрудников уголовно-исполнительной системы в процессуальных действиях, которое в силу своей специфики имеет определенные особенности. В процессе исследования особенностей участия сотрудников уголовно-исполнительной системы рассмотрен вопрос о разграничении и понимании процессуальных полномочий, принадлежащих органам и сотрудникам УИС. Особое внимание уделено вопросу процессуального статуса начальников учреждений и органов уголовно-исполнительной системы как органов дознания, а также делегирования полномочий сотрудникам розыскных отделов, производящих неотложные следственные действия. Данный вопрос является актуальным в связи с тем, что на протяжении нескольких десятков лет существуют различные точки зрения относительно объема присущих процессуальных полномочий ФСИН России и ее отдельным подразделениям. В своей работе мы придерживаемся позиции, что осуществлять процессуальные действия правомочны оперативные подразделения учреждений УИС и начальник исправительного учреждения. Проанализировав особенности осуществления сотрудниками ФСИН России процессуальных полномочий, авторы пришли к выводу о конкретном объеме, необходимом для выполнения служебных обязанностей. В статье сделаны предложения о внесении изменений в российское уголовно-процессуальное законодательство.

Penal officers the Russian Federation exercise the powers assigned to them by federal law aimed at ensuring the execution of punishments. Such powers should also include the participation of penal officers in legal proceedings, which, due to its specificity, has certain features. In the process of studying the features of the participation of penal officers, the issue of delineation and understanding of the procedural powers belonging to the bodies and penal officers was considered. Particular attention is paid to the issue of the procedural status of the heads of institutions and bodies of the penitentiary system as bodies of inquiry, as well as the delegation of authority to employees of search departments that carry out urgent investigative actions. This issue is relevant due to the fact that for several decades there have been different points of view regarding the scope of the inherent procedural powers of the Federal Penitentiary Service of Russia and its individual divisions. In our work, we adhere to the position that the operational units of the institutions of the penal system and the head of the correctional institution are competent to carry out procedural actions. After analyzing the peculiarities of the exercise of procedural powers by the employees of the Federal Penitentiary Service of Russia, the authors came to the conclusion about the specific amount necessary to perform official duties. The article made proposals to amend the Russian criminal procedure legislation.

Timing of internal processes: Investigating introspection about the costs of task switching and memory search
Authors: Bratzke Daniel , Bryce Donna
Published: May 2022

During the last two decades, there has been new interest in introspection about multitasking performance. In this field, subjective timing of one’s own reaction times (introspective RTs) has proven a useful measure to assess introspection. However, whether timing our own cognitive processing makes use of the same timing mechanisms as timing external intervals has been called into question. Here we take a novel approach to this question and build on the previously observed dissociation between the interference of task switching and memory search with a concurrent time production task whereby temporal productions increased with increasing memory set size but were not affected by switch costs. We tested whether a similar dissociation could be observed in this paradigm when participants provide introspective RTs instead of concurrent temporal productions. The results showed no such dissociation as switch costs and the effect of memory set size on RTs were both reflected in introspective RTs. These findings indicate that the underlying timing mechanisms differ between temporal productions and introspective RTs in this multitasking context, and that introspective RTs are still strikingly accurate estimates of objective RTs.

Novel pyridine-based fluorescing compounds, viz. pyrido[1,2-a]pyrrolo[3,4-d]pyrimidines 3a,b and N-methyl-4-((pyridin-2-yl)amino)maleimides 4a–e, were selectively prepared by a one-pot reaction between a functionalized maleimide and 2-aminopyridines with electron-donating or electron-withdrawing groups at position 5 and were investigated photophysically and computationally. The photophysical studies revealed that all the synthesized compounds exhibited fluorescence in organic solvents, while N-methyl-4-((pyridin-2-yl)amino)-substituted maleimide derivatives 4a–e, which are based on an acceptor–donor–acceptor (A–D–A) system, exhibited aggregation-induced emission enhancement (AIEE) properties in aqueous media. Compounds 4a and 4e, bearing electron-withdrawing groups (Br and CF3, respectively) showed 7.0 and 15 times fluorescence enhancement. Time-dependent density functional theory (TD-DFT) calculations were performed to gain better insight into the electronic nature of the compounds with and without AIEE properties.

The development of commodity exchanges is promoted as one of main competition policy directions in Russian energy markets. Exchange trade has a number of procompetitive effects based on reduction of market transaction costs, as well as on prevention of price manipulations. Those effects in their turn contribute to less painful coping with economic shocks and imbalances, which acquires a special importance amid crisis circumstances of 2020 and 2022. However, exchange trade is connected with its own risks and constraints, in particular under the shortage of liquidity, excessive market concentration or abusive practices supported by a weak regulation. This paper contains the empirical analysis of the dependence between structural and pricing indicators in the markets for natural gas and diesel fuel on Saint-Petersburg International Mercantile Exchange. It is discovered that the excessive concentration in natural gas markets negatively affects price stability and market liquidity – development of this trading segment requires more active involvement of independent suppliers. At the same time, this involvement should be realized not by directive measures but by additional opportunities of exchange trade. This dependence is more complicated in markets for diesel fuel – it is necessary to continue the policy of supporting the volume of liquidity while increasing the attractiveness of the trading conditions for different groups of market participants. As such, there should be different policies to promote commodity exchanges developments in different markets, and those policies may change follow market evolution. At the same time, discretionary anti-crisis measures should be avoided, if they increase uncertainty on commodity exchanges and lower incentives for their development.
Concentration and Competition in Modern Banking Sector of Serbia: Changes and Decomposition of Herfindahl – Hirschman Index
Authors:   Nizhny Novgorod State Engineering and Economic University, Bukvić Rajko M.
Published: May 2022

Paper considers the concentration (and competition) and changes in concentration in banking sector of Serbia (without Kosovo and Metohia) in the second half of 2010s and beginning of 2020s. In the first part of work the main theoretical and methodological questions of the research of concentration and competition were presented, and after them the specific characteristics of competition in banking sector, as one of the form of competition. Author emphasizes the importance of the choice of balance variables for the calculation of concentration indices and chooses next variables: total assets, deposits, capital, operating income, and loans. In the next part using the Herfindahl – Hirschman index, one of the most popular methods, it was shown that the degree of concentration is low, although close to moderate. At the end, on the basis of very rare used method it were decomposed the changes of this concentration index into two factors: component of inequality in market shares distribution, and component of the number of banks. It was shown that impacts of these two factors are not equal and vary through the years. All the types of its varying were classified into six groups depending on types of these factors changes and its relationships. Among the six possible types of changes the type VI prevails in many cases (decrease of inequality of market shares and decrease of number of banks where the first change is greater than second). On the other side, in 2021 (I–VI) for all variables type of changes I happens (increase of inequality and decrease of number of banks). Very interesting is also the fact that in general concentration index was not increased, although the number of banks constantly decreased and component of inequality in many cases had greater impact on the changes of concentration index than the component of inequality.

The article outlines the problems of marketing research of a potential market for a startup entering the market. The complexity of analyzing potential demand lies in the lack of information and low reliability of evaluation methods, especially if the product is innovative. The purpose of the study is a comprehensive comparative analysis of methods for assessing the potential startup market, depending on the level of business innovation. The article shows the synthesis of the application of the methodological approach of the theory of industry markets and marketing tools for the study of consumer demand, assessment of the intensity of competition. To achieve this goal, the following tasks were solved: the definition of a startup was given, the boundaries of the local recording market in the city of Novosibirsk were determined; the market structure and competitive environment were assessed using various research methods; the level of economic concentration was calculated. The authors have attempted to systematize various methods of market research with an indication of their advantages and disadvantages to determine the potential niche of a startup. Based on the conducted empirical research, it was found that for existing and non-segmented markets, when a startup has innovative features, it is possible to use any research method. For new commodity markets (services), their circle is narrowing. It is recommended to use the analysis of key queries at the first stage, and TAM SAM SOM at the second stage. The methodology of the theory of industry markets allows not only to analyze the market by key structural parameters, but also to predict the behavior model of a startup company at each stage of its development. Michael Porter's methodology helps to understand the main driving forces, the main risks that can have a positive impact on business development. The right choice of marketing tools determines the success of a beginner in achieving economic targets. The scientific novelty lies in the synthesis of the application of the methodology of the theory of industry markets and marketing tools for the study of consumer demand, assessing the intensity of competition and justifying the feasibility of using each approach depending on the innovativeness of the startup.

To overcome the problem of customers' large electrical power loads, it is necessary to improve the power factor so that power can be used optimally. In determining the power factor improvement, it is essential to know the percentage of repair needed. This study aimed to determine the effect of Cosφ on the power consumption of single-phase prepaid kWh meters and the percent improvement of Cos to improve the power factor of consumers. This research was conducted using the direct measurement method at the customers' houses. The measurement of power consumption resulting from electrical measurements was carried out according to PLN standards. The results showed the effect of Cosφ on electric power consumption at 2,200 VA of 12,765 Watt, 1,300 VA of 7,02 Watt, 900 VA of 8,696 Watt. Meanwhile, the percentage of improvement in Cos" was to improve the power factor at 2,200 VA power of 3.961%, 1,300 VA power of 2.941%, 900 VA power of 7.254%. Keywords: Power Factor Improvement; kWh
Inverse Kies distribution: Properties and applications
Authors: Kumar C. Satheesh , Dharmaja S. H. S.
Published: May 2022

In this paper, a new class of distribution namely “the inverse Kies distribution” is proposed and some of its important aspects are studied by deriving expressions for its percentile measures, raw moments, reliability measures etc. The maximum likelihood estimation of the parameters of the distribution is discussed and the distribution has been fitted to certain real life data sets. The asymptotic behaviour of maximum likelihood estimators of the parameters of the distribution are also studied by using simulated data sets. Keywords: Beta generalised inverse Weibull distribution, Failure rate, Generalised inverse Weibull distribution, Maximum likelihood estimation, Model selection, Percentile measures

Published: May 2022

Discrete distributions with bathtub shaped hazard rates have recently become of interest in reliability modelling and analysis. In the present work, we address the problem of obtaining distributions having such hazard rates when the lifetime is discrete. The methods considered here include discretising continuous bathtub models, construction using the score function, construction from decreasing hazard rate distributions and some other methods currently available in the continuous case. We discuss properties and applications of the discretised quadratic hazard model which has a bathtub shaped hazard rate. Keywords: Bathtub hazard rate, Discrete distribution, Quadratic hazard model, Score function, Upside down bathtub hazard rate
Evaluating risk in precious metal prices with generalised lambda, generalised pareto and generalised extreme value distributions
Authors: Chinhamu Knowledge , Huang Chun-Kai , Chikobvu Delson
Published: May 2022

In this study we investigate the performance of the generalised lambda distribution (GLD), the generalised Pareto distribution (GPD) and the generalised extreme value distribution (GEVD) in modelling daily platinum, gold and silver price log-returns. Our primary goal is to compare GLD against GPD, and GEVD, in the estimation of Value-at-Risk (VaR) and expected shortfall (ES) as per the international Basel regulatory framework. Our analyses show that GPD and GLD generally outperform GEVD for VaR and ES estimation for negative precious metal returns. For gold, the GPD stands out as the most suitable model. For platinum, GPD and GLD are equally adequate, especially at the 1% VaR level. For silver, GLD is the most suitable at 1% VaR level, whereas GPD is the best model at 0.1%. This study has shown that GLD is a suitable model for extreme risk in precious metal prices and can be used for the estimation of VaR and ES values.

Background: This study aims to elucidate the associations among dietary seaweed (gim and miyeok/dashima) and iodine intakes, the rs77277498 polymorphism of the SLC5A5 gene codifying the sodium/iodine symporter, and thyroid cancer risk in a Korean population.Methods: We conducted a case-control study of 117 thyroid cancer cases and 173 controls who participated in the Cancer Screenee Cohort between 2002 and 2014 at the National Cancer Center, Korea. The amount of seaweed and iodine consumption (g/day) was estimated using the residual energy adjustment method. We calculated odds ratios (ORs) and their 95% confidence intervals (CIs) using a multivariable logistic regression model for the separate and combined effect of dietary iodine-based intake and SLC5A5 polymorphism (rs77277498, C>G) on thyroid cancer.Results: Dietary gim and iodine intakes were inversely associated with thyroid cancer, with ORs of 0.50 (95% CI, 0.30 to 0.83) and 0.57 (95% CI, 0.35 to 0.95), respectively, whereas the associations for dietary miyeok/dashima and total seaweed intakes were not significant. However, compared with individuals carrying the C/C genotype of the rs77277498 polymorphism with a low intake of all dietary factors, those carrying the G allele with a high intake had a lower risk of thyroid cancer, with ORs of 0.25 (95% CI, 0.10 to 0.56), 0.31 (95% CI, 0.12 to 0.77), 0.26 (95% CI, 0.10 to 0.62), and 0.30 (95% CI, 0.12 to 0.73) for the consumption of gim, miyeok/dashima, total seaweed, and iodine, respectively.Conclusion: In summary, our results supported the evidence of the protective effects of dietary gim and iodine intake against thyroid cancer risk, and this association can be strengthened by SLC5A5 rs77277498 genotypes.

Authors: Tetrevova Libena , Kopriva Jan , Zahorska Alexandra
Published: May 2022

The sharing economy model and the concept of corporate social responsibility (CSR) represent important phenomena in the world of business today. The aim of this article is to characterise the current state of knowledge of the context of the sharing economy and CSR, to identify research gaps and to suggest possible directions for future research in this area. Using a standalone literature review, an analysis was performed of studies published on this topic in publications indexed in the Web of Science and Scopus databases. In view of the fact that this topic is not yet part of mainstream research, only 20 publications published between 2017 and 2021 were analysed. The analysis performed shows that the context of the sharing economy and the concept of CSR are being investigated by researchers both in a general context and from the perspective of sharing economy platforms. However, significant research gaps exist in the investigation of the context of these two phenomena, which could be filled by investigation in the areas specified in the article.

Long-term studies on hemispheric asymmetry can help to understand better the solar dynamo. We present the hemispheric sunspot number calculated from daily sunspot observations made at the Madrid Astronomical Observatory for the period 1935–1986 (corresponding approximately to Solar Cycles 17–21). From this data set, we also analyzed the asymmetry index and hemispheric phase shifts. We conclude that the northern hemisphere was predominant in Solar Cycles 17–20, whereas the southern hemisphere was predominant in Solar cycle 21. The strongest asymmetries are found in Solar Cycles 20 (with a relative difference between both hemispheres of 44%) and 19 (39%). A normalization of the Madrid hemispheric sunspot number was also made with respect to the sunspot number (Version 2). Our results agree with previous studies on hemispheric asymmetry around the mid-20th century and their secular trends.
