Authors: Schlegel Petr , Křehký Adam , Dostálová Radka
Published: October 2021

Social media is part of the lives of young adults. Their influence extends to health behavior or nutrition. “Fitness challenges” often appear and they should affect the motivation to exercise, body composition changes, performance improvement. 67 healthy young adults (32 women, 20.3 years; 35 men, 20.8 years) took part in the “challenge”, where they completed 3 series of 12 – 15 push-ups every day for 30 days. After the intervention, both groups showed a statistically significant (α = 0.01) improvement, women 5.8 repetitions, men by 7 repetitions. The research was supplemented by a questionnaire, which showed a positive effect on increasing motivation for this activity. Furthermore, it has been shown that “fitness challenges” bring obvious health risks that need to be taken into account. It seems that with the optimal setting of the content of the exercise program, the “fitness challenge” can be a good instrument of increasing the physical acitivty, motivation to exercise, and positively influencing strength performance.
Covid-19 and Unemployment: Evidence from Puerto Rico Using Bayesian Analyses with High-Frequency Data
Authors: Toledo Wilfredo
Published: October 2021

The paper aims at determining the relationship between the Covid-19 contagion level and the state of the economy using high-frequency data from Puerto Rico. In order to achieve the aim set, the direction of the causality relationship between the numbers of infected persons and the unemployment rate was determined. Furthermore, various Bayesian statistical models were estimated. The analysis results imply that the unemployment rate responds moderately to the Covid-19 contagion level itself and not the other way around. The 95 % credible interval for the elasticity coefficient of the unemployment rate relative to the virus is estimated as [0.0140–0.1448]. Evidence also shows that at the beginning of 2021, most of the fluctuations in the unemployment rate were explained directly by the Covid-19 perturbations. Hence, no evidence was found that economic activity promoted the virus spread in the analysed economy.

Published: October 2021

The paper aims to verify the Job Performance Model based on Employees’ Dynamic Capabilities (EDC) and explain the mechanisms shaping job performance based on EDC in an initial phase of the crisis in an organisation due to the Black Swan phenomena, on the example of the COVID-19 pandemic of 2020. Empirical research on Italian organisations affected by the crisis shows that the Model is significantly distorted under such conditions. To verify the internal structure of the Job Performance Model based on EDC under critical conditions, the statistical correlation analysis, linear regression analysis and path analysis were executed using SPSS and SPSS AMOS. The research result of the statistical analysis confirmed that the new version of the Model for organisations under the Black Swan phenomenon was statistically significant without work motivation and job satisfaction. It was also proven that P–J fit still linked EDC and job performance through strengthening work engagement. The research confirmed that the Job Performance Model based on EDC, which has so far been verified under normal working conditions, radically changed its structure during the COVID-19 crisis. This means that factors previously considered important in the Job Performance Model based on EDC have become insignificant in shaping job performance. Therefore, this is an inspiration for further research to verify the Job Performance Model based on EDC in different phases of the crisis.

Published: October 2021

The coronavirus pandemic is a crisis that disrupts the global supply chain and slows down the world economy. A significant challenge for the companies in the manufacturing sector is to mitigate risks related to the COVID-19 outbreak. Grounded in the resilience theory, resilience (i.e., prepare, prevent, protect, respond, and recover processes) aims to manage risks and ensure business continuity. This research aims to identify the key factors for the resilient manufacturing management of Thai automotive industries during the COVID-19 outbreak. Three outstanding companies of tier 1 automotive suppliers have been selected as case studies in this work. This qualitative research was completed by using a semi-structured interview. The target interviewers were CEOs or general managers. The data analysis was divided into two phases. Phase one summarised the interview data of each company. Phase two used thematic analysis and cross-case analysis to identify resilience practices’ patterns, themes, and multi-factors. The findings indicate three key factors to enhance resilience: leadership, technology, and the firm’s experience in handling emerging events. Together, these factors help enterprises to prepare for Business Continuity Planning (BCP), improve supply chain management, and increase the firm’s ability to recover from disruption situations. This paper contributes to the literature on the supply chain resilience in the automotive industry by providing a guideline for firms to implement resilience practices, improve business operations, and increase firm’s capabilities, both as human skills and technologies, to deal with a novel crisis. Resilience practices response to the COVID-19 outbreak not only helps the companies minimise business disruption in the short-term but also includes the long-term response strategies for unknown events. For this purpose, the case study research was conducted to investigate the resilience strategies during the COVID-19 pandemic and determine the critical success factors of resilience implementation in the Thai automotive industry.
Partial replacement of cement with rice husk ash in concrete production: an exploratory cost-benefit analysis for low-income communities
Authors: Muleya Franco , Muwila Natasha , Tembo Chipozya Kosta , Lungu Alice
Published: October 2021

Cement is an important construction material in concrete production; however, it is expensive and unaffordable for many low-income and rural communities in developing countries. Rice husk is a by-product from the rice mill process, with an approximate ratio of 200 kg rice husk per one tonne of rice produced. This experimental study aimed to investigate the integrity of concrete produced in Zambia using rice husk ash (RHA) to partially replace cement. The primary goal was to carry out a cost–benefit analysis on the use of RHA in concrete. RHA was used to partially replace cement with ratios of 10 %, 20 % and 30 %. The 20 % cement replacement mix produced the optimum 18 MPa concrete strength results at a 0.5 water/binder ratio. This translated in cost reduction of concrete by 12.5 %, which is particularly significant for higher concrete volumes. The produced concrete is suitable for lightly loaded structures, such as foundation footings, surface beds and walkways to benefit low-income communities. The study further concluded that the RHA based concrete was more cost-efficient in structures that were close to areas of rice production due to reduced RHA transportation costs.

Authors: Mendala Oliwier , Kozuba Jarosław
Published: October 2021

The aim of the study is to present the principles of civil liability for damage caused to a passenger for which an air carrier is responsible, regulated by the Warsaw and Montreal Conventions, and the norms of national law providing issues that are not included in international law acts. The paper presents a historical overview of the applicable Conventions. The provisions of the Polish Civil Code that are useful for interpretation of law institutions and complement the legal norms contained in the Conventions are also presented. The compiled issues put the legal norms contained in various law systems in order by indicating the practical dimension of the pursuit of potential claims by passengers vis-à-vis air carriers. This is followed by a discussion of the grounds for excluding third party liability of an air carrier in case of excessive or illegitimate claims of the carrier’s clients, and of the insurer.

Authors: Abdunazarov Jamshid , Mikusova Miroslava , Kyamakya Kyandoghere
Published: October 2021

In Uzbekistan, about 2,000 people die every year as a result of a traffic accident. At the same time, according to the Pulitzer Centre on Crisis Reporting, the Republic has the lowest rate in road mortality among the countries in the Central Asian region - for every 100,000 people, it is 11.32 people. Losses from road accidents in Uzbekistan equivalent up to 2.8% of GDP that is also one of the lowest indicators. But according to traffic safety experts, the losses from accidents are greater than reported data. Nowadays there are a lot of methods to analyse and ensure road safety and traffic management on the roads. The authors believe that road safety is a complex societal problem not only in Uzbekistan but all over the world. One of these methods is System Dynamic (SD) and COMplex PRoblem hAndling Methodology (COMPRAM). In this work, the Vensim PLE SD software tool (it is one SD tool amongst many others) has been used to perform the SD modelling of the case study at hand. In the methods of system dynamics, a computer model is created using a graphical technique for constructing flow diagrams and causal relationships of the system under study and then simulated on a computer. COMPRAM allows us to figure out the way to handle complex societal problems while involving a System Dynamics (SD) simulation option. There are similarities between COMPRAM and the traditional way of analysing road safety. In traditional ways, each element or factor is studied as a separate phenomenon. These indicators are studied in the stages of COMPRAM. This article has been studied a different aspect of how road accidents happen. The developed a comparison (according to six criteria) of the different modelling paradigms which have been historically used to assess road safety. Also, the authors made a comparison of the COMPRAM methodology with the traditional road safety assessment approach to highlight similarities and differences.

Published: October 2021

The operational technique for the major components of the fighter aircraft engine rotors has been introduced basing on the real conditions of their cyclic loading in each flight or ground test and a priori information on their previous operation. It has been confirmed that the obtained technical solutions not only conform to the current methods of accounting for the depletion of the life cycle of the Afterburning Turbofan Engine (ATE) but also introduce additional opportunities to consider individual characteristics and conditions of their cyclic loading throughout the overall operating time. A method for estimating the depletion of the life cycle in accordance with the Total Accumulated Cycle (TAC) has been proposed. It allows us to compare the actual operating time of the ATE in hours and the accumulated value of cyclic damage to the engine and its major components (within the TAC parameter) during the previous operation.

Published: October 2021

Structural health monitoring system plays a crucial role in order to ensure a well-maintained bridge condition. There are a number of methods that may be utilized in order to conduct the monitoring process, namely the use of Global Positioning System (GPS). Despite its accuracy, the use of GPS is deemed costly. A more practical and economical approach to predicting deflection is the use of tiltmeter to obtain rotational values. This research studied the accuracy of simple span steel box girder deflection that is obtained from regression formulae. The analysis showed that a 3D linear and quadratic regression with two rotation data provided the best accuracy if compared with 2D. Keywords: deflection; rotation; structural health monitoring system; tiltmeter AbstrakPemantauan kesehatan struktur jembatan (structural health monitoring system) sangat penting dilakukan untuk memastikan jembatan tetap dalam kondisi yang memadai. Banyak cara yang dapat dilakukan untuk memonitor kondisi jembatan, salah satunya dengan menggunakan Global Positioning System (GPS). Walaupun menghasilkan data yang akurat, penggunaan GPS dipandang menghabiskan biaya yang relatif besar. Adapun solusi yang lebih praktis dan murah untuk memprediksi defleksi yaitu dengan menggunakan tiltmeter dengan data rotasi. Pada studi ini, telah dipelajari tingkat akurasi defleksi jembatan steel box girder dengan bentang sederhana dari hasil persamaan regresi dengan data rotasi. Hasil analisis menunjukkan bahwa model regresi linear dan kuadratik 3D untuk 2 data rotasi memiliki tingkat akurasi lebih baik jika dibandingkan dengan model regresi linear dan kuadratik 2D untuk 2 data rotasi.

Published: October 2021

During this paper, new Schiff's base derivatives [F1-F5] were prepared through the reaction of dapsone drug with different substituted benzaldehyde compounds. Schiff's bases were then converted into 2,3-dihyroquinazolin-4(1H)-one derivatives [F6-F10] through the reaction with 2-amino benzoic acid in ethanol. The synthesized compounds were identified by their physical properties using UV-Vis, FT-IR and 1H-NMR analyses. The liquid crystalline properties of some prepared compounds revealed smectic and nematic phases. Using two separate bacterial species, Pseudomonas aeruginosa (Gram -ve) and Staphylococcus  aureus (Gram +ve), the antimicrobial activities of certain synthesized compounds [F1,F2,F7,F8] were investigated using the agar diffusion process. The findings revealed that some of the assayed compounds had antimicrobial activities against the bacteria tested.
Heritage Preservation as Strategy for Recomposing Conflict Territories
Authors: Pages Madrigal Jose Manuel
Published: October 2021

Heritage admits diverse readings depending on different territorial spaces, contexts, and knowledge fields. The relation between Heritage and the social contexts is one of these knowledge areas. But Heritage accepts a dual perception as a cultural reflection. It may be considered either as the origins of the conflicts or the engine for recomposing disrupted territories. The paper proposes a reflection on the topics related to conflict territories and the roles currently played by Cultural Heritage. The recomposition of conflict territories is based on a continuous intercultural approach with important contributions from human rights, genders equality, intercultural dialogue perspectives and the fact of taking heritage as a territorial stabilization factor. The paper presents specific practical cases in the Eastern Mediterranean region where actions on Heritage religious elements collide with the national sovereign of the respective current countries. A comparative study among these different actions proves that the initial clashes can be progressively transformed into strategies able to become the future guideline for the resolution of heritage regional conflicts. These conflicts reflect two discourses: political (with strong links between national identity and religion) and scientific (with a clash between static concept and dynamic vision) where objects interact with the visitors.

Published: October 2021

The aim of the study was to determine the level of use of fermented snail meat protein hydrolyzate (FSMPH) as a reduction of fish meal (FM) in the ration, and its effect on the production performance of “super” native chicken (SNC). Research materials were SNC unsexing and FSMPH. The study used an experimental method with a completely randomized design with 5 treatments and 4 replications. The research ration treatments were: P0 = FM 8% without FSMPH (Control), P1= TI 6%+FSMPH 5 ml/kg ration, P2= TI 4%+FSMPH 10 ml/kg ration, P3= TI 2%+FSMPH 15 ml/kg ration, P4= TI 0%+FSMPH 20 ml/kg ration. The results showed that the a reduction of FM with FSMPH on SNC ration consumption at each level had no significant effect (P>0.05) on control feed, BW, BWG, and FCR in P1, P2, and P3 treatments on control feed, but showed a significant difference (P<0.05) in lower BW, BWG, and higher FCR in P4 treatment of SNC fed with 8% (control). The conclusion was that FSMPH can be used as a reduction  for FM up to 75% of the use of FM in the ration as much as 8%.

Published: October 2021

River water quality modeling needs appropriate and suitable coefficients especially in application for specific river like urban river. Aim: This study aims to determine the value of the coefficient with a short term duration and a variable test time span.  Several ways and methods of determining the rate of deoxygenation are developed according to the characteristics of the river and the environment. Modification method was applied in this research in which the test time span was unequal. The river chosen in this study is the Citepus River, Bandung, Indonesia representing an urban river in a tropical country. Methodology and Results: Sampling was carried out in the dry season. The laboratory analysis method used in determining the rate of deoxygenation uses the Slope Method of data from the short term incubation, which is ten days. The results showed that the Thomas Slope method's deoxygenation rate (K1) was 0.095 per day in the upstream segment, 0.917 per day in the middle segment, and 0.180 per day in the downstream segment. While the Ultimate BOD (La) value is 46.95 mg/l in the upstream segment, 38.70 mg/l in the middle segment, and 37.60 mg/l in the downstream segment. Conclusion, significance, and impact of study: The results of this study show that the value of the deoxygenation rate is similar to the theoretical surface water conditions. However, in the upstream segment, there is still a low deoxygenation rate value due to non-optimal activity of microorganisms. This findings will be very useful both in water quality modeling and river management.

Criminogenic role of “private patronage” as a corruption-causing factor in the judicial act in light of the activity of modern “mafia” groups
Authors: Novitskaya Nadezhda Pavlovna
Published: October 2021

This article explores the causes for the emergence of “corruption-causing factors” in judicial acts, indicates correlation between “corruption-causing factors” and “private patronage” on the part of mafia institution (modern mafia groups), which is the highest “specific economic enterprise or industry that produces, encourages, and sells private patronage”, including interference in justice through corruption and bribery. The case law on the topic is analyzed. The object of this research is the activity of judges in assessing legally valid circumstances in relation to the responsibility of judges. The subject of this research is the norms of Russian legislation that regulate the activity of judges in assessing legally valid circumstances, as well as the texts of judicial acts on claims under the Article 125 of the Criminal Procedure Code of the Russian Federation, civil and administrative cases of the courts of St. Petersburg, and the responsibility of judges. The author notes the absence of definition of “corruption-causing factor” in the judicial act, its characteristics, responsibility of the judges for decision-making that contain “corruption-causing factor”, effective judicial bodies that “investigate” the disciplinary misconduct of judges. It is underlined that the implementation of the institution of investigative judge was anticipatory. The scientific novelty is substantiated by the fact that this article is first to outline the concept of “corruption-causing factor” in the judicial act as the grounds for bringing the judge to disciplinary responsibility. The conclusion is made that this is a comprehensive issue; thus, the longer it would take to solve the questions of effective legal regulation of the mechanism of judicial responsibility, the more it would augment the risks of proliferation of the “corruption-causing factor” in the judicial system, which destroys confidence in the government authorities and deteriorates the state from within.

Published: October 2021

This article is a sequence of research conducted by the authors on the topic of offences related to digital securities fraud (Part 2). It completes the design of the system of such offences, determining the “subsystem” that considers the economic nature of the Central Securities Depository. For this purpose, analysis is conducted on the articles of the Criminal Code of the Russian Federation that form the system of offences related associated with the fraud of non-digital securities (Articles 185-186) from the perspective of their applicability to digital securities and peculiarities of such application. The research is based on the systemic approach, comparative-legal method, logical techniques of analysis and synthesis of information, as well as the method of deduction. The authors conclude on applicability of the Articles 185, 185.1, 185.2 and 185.4 of the Criminal Code of the Russian Federation to unlawful acts related to digital securities, taking into account the specificity of their legal regulation, namely the absence of necessity of state registration of stocks in the form of digital financial assets, the registration of rights to central securities depository by the information system operator that issued them, etc. Summarizing the results of this research with the results acquired in the Part I, the authors form the system of offences associated with the digital securities fraud, which includes the aforementioned elements, as well as the elements stipulated in the Article 187.1 “Organization of illegal trafficking of digital Rights” of the Draft Federal Law “On Amendments to the Criminal Code of the Russian Federation”. The Russian legal science unfortunately does not give due attention to examination of this problem, and such system is developed for the first time. The authors anchor hopes that the system of offenses they have designed would be effectively used in the law enforcement practice in the context of classification of unlawful action associated with central securities depository.

Authors: Rouvinsky Roman Z.
Published: October 2021

The subject of this article is the problem of correspondence of the practices of digital profiling and social score, which imply collection and analysis of biographical (reputational) information, to the worldwide-accepted standards of protection of personal data and privacy. Analysis is conducted on the legislation of the People's Republic of China – the country that in recent years has implemented the “Social Credit System” in the sphere of public administration. This project consists of management practices, which are viewed through the prism of the legal model of personal data protection formed by the Law in Protection of Personal Information adopted in 2021. The peculiarity of this research is its comparative legal nature: the provisions of China’s legislation are juxtaposed to the provisions of the General Data Protection Regulation adopted in the European Union and Russia’s Federal Law “On Personal Data”. Assessment is given to the European and Russian models of regulation of operations with personal data in the context of possible implementation of digital profiling practices, social score (ranking, grading), and automated law enforcement decision-making. Having determined the gaps in the current Russian and EU legislation on personal data, and indicating the risk caused by the presence of blanket rules, the conclusion is made according to which the modern legislation on personal data can be an obstacle for arbitrary use of such data; however, it cannot stop the implementation of innovative technologies, mechanisms and practices that suggest using registry and biographical information of individuals for the purpose of social control into the public administration.

Based on the example of national research universities, the article examines the peculiarities of international activity and opportunities for the Russian universities to participate in the international academic mobility. Primary focus is given to the student international internships, which are considered as highly effective educational and mentoring practices. The theoretical framework for this research is comprised of a set of provisions that characterize international academic exchange as mutually beneficial interaction of different values, cultures, experience, knowledge, interests, and goals. The scientific novelty lies in introduction of the new empirical self-examination reports of the universities, use of various statistical data and rating results. The conclusion is made that international academic mobility has its own structure, pronounced geographical focus, and industry characteristics. Cooperation with individual foreign universities and enterprises, as well as with international university associations and branch associations is well developed and creates favorable environment for the advancement of international academic mobility. However, these opportunities are not used to the fullest, as testified by relatively low number of the Russian participants, prevalence of incoming flow vs outgoing, and unequal conditions for the capital and regional universities.

Authors: Isaev Dmitry Petrovich
Published: October 2021

The object of this research is the image of professional dynasty that exists in collective perception of pedagogical staff of the Russian universities. The goal of this work lies in outlining mental space, which actualizes various connotations of the image of professional dynasty and dynasticity as the social practice in modern Russian society. For achieving the set goal, the author conducts a comparative analysis of positive and negative assessments of dynasticity, and reveals the factors that determine critical attitude in the university environment. The article is based on the questionnaire method with subsequent calculation of raw data, generalization and analysis of quantitative data; applies contextual interpretation of the qualitative data. According to the acquired data, an outwardly positive outlook upon professional dynasties is adjusted through comprehensive analysis of response groups. Attention is turned to the fact that the positive image of dynasticity is not extended to such spheres as law enforcement agencies and state administration. It is established that positive assessments rather correlate with personal values, while negative – with socially oriented values. The conclusion is made that professionalism is not the key factor in representations of the academic staff on the advantages of dynasticity, which indicates latent non-recognition of its advantages overall. Ambiguous attitudes with regards to professional continuity for their families should also be viewed in terms of overall criticism towards dynasties in Russian modern social space.
