Trends of Academic Mobility in Russia: Statistical Analysis and Forecasting
Authors: Rostovskaya Tamara K. , Zolotareva Olga A.
Published: September 2021

Introduction. Currently, the competitiveness of universities is determined by their level of internationalization, which cannot be imagined without academic mobility. This is reflected in world university rankings. Russian universities do not occupy leading positions in these ratings; they are losing their role in the global educational space. Today, it is necessary to make prompt, constructive decisions that contribute to the growth of academic mobility, however, the development of measures in this area is not possible without prospective estimates of indicators characterizing both the development of the internationalization of higher education and growth quality of education. In this regard, the purpose of the presented article is to build predictive scenarios for academic mobility in Russia.
Materials and Methods. The research employs statistical methods of time series analysis and forecasting. Prospective values of the number of foreign citizens from various countries studying at Russian universities were obtained on the basis of exponential functions and adaptive forecasting methods. The choice of the model with the best forecast values is based on a formal-logical analysis coupled with a comparison of the main characteristics of accuracy and quality.
Results. The article presents predictive scenarios of academic mobility in Russia: regressive, conservative, moderately optimistic. The obtained forecast results determine the possibilities of increasing the competitiveness of Russian education and improving the position of Russian universities in the world rankings only if highquality digital education is formed and developed on the basis of an infrastructure that ensures high technical reliability.
Discussion and Conclusion. The proposed methodology and assessments of the prospective values of the targets for the growth of university academic mobility not only substantiate the expansion of the possibilities of using adaptive forecasting methods, which determines the scientific contribution of the study conducted by the authors, but can also be taken into account when adjusting/updating the planned values of indicators introduced into state initiatives to stimulate internationalization of Russian higher education, which points to the high practical importance of this article.
Development of the Psychological System of Pedagogical Abilities of Students – Future Primary School Teachers
Authors: Mazilov Vladimir A. , Slepko Yurii N.
Published: September 2021

Introduction. Psychological and pedagogical support for the professionalization of a teacher should be based on modern knowledge in the development of pedagogical abilities. The most popular strategy for studying abilities is still the analytical approach, which does not allow to consider abilities as a holistic, continuously developing psychological education. The purpose of the article is to present the results of research into the development of the psychological system of pedagogical abilities of students – future primary school teachers in the context of continuous pedagogical education at secondary school, pedagogical college and pedagogical university.
Materials and Methods. The survey involved 201 subjects, including students of the pedagogical class (n = 15), students of the vocational pedagogical college (n = 82), students of the pedagogical university (n = 104). In order to study the psychological system of pedagogical abilities, test methods, questionnaires, self-assessment scales, as well as an analysis of indicators of academic performance were used. The analysis of the psychological system of abilities was made by using systemic indices (coherence, divergence, organization), assessing the homogeneity/ heterogeneity of structures, identifying the basic and leading components of the system.
Results. The uneven development of the psychological system of pedagogical abilities at different levels of pedagogical education was shown. It has been established that the development of the system of pedagogical abilities during the period of study at school, college and university cannot be characterized as continuous. Students of the pedagogical class are characterized by a higher organization of the ability system than those in college and university; for college students – their continuous restructuring and a decrease in organization by the end of their studies; for university students – a more stable and progressively developing system of abilities. Qualitative differences in the structural organization of the system are determined by the different contributions of the types of abilities (individual, subjective, personal) to its functioning and achievement of academic results. The organization of the system of abilities of schoolchildren is largely determined by the abilities of an individual, college students – by the abilities of a subject of activity and personality, university students – by the abilities of an individual.
Discussion and Conclusion. The conclusions formulated in the research paper serve the basis for the organization of special activities on the purposeful formation of the system of pedagogical abilities in the conditions of continuous pedagogical education.

Authors: Baeva Irina A. , Gayazova Larisa A. , Kondakova Irina V.
Published: September 2021

Introduction. The relevance of the study is determined by the importance of the category “psychological safety” for the support of the life quality of modern people, which is influenced in a complicated way by physical health, psychological well-being, value preferences, features of social relations and their relation to the characteristic features of the environment. The state of psychological safety is a significant factor ensuring the effectiveness of еducation, upbrining and development of the younger generation. However, the personal resources that contribute to the support of this state among adolescents and young people in the educational environment are more understudied. The purpose of the article is to determine the resources of adolescents, which are the predictors of the state of psychological safety.
Materials and Methods. The method “Psychological safety of the educational environmentˮ developed by I.А. Baeva was used to study students’ level of psychological safety. The method of S. Schwartz was used to assess the personality’s value orientations, to assess the level of psychological well-being – were used Ryff Scales of Psychological Well-Being (RPWB), the level of loneliness – UCLA Loneliness Scale (D. Russell, M. Ferguson), the level of hopelessness – Hopelessness Scale, Beck et al., the level of social intelligence – Tromsø Social Intelligence Scale, the level of aggression – Buss-Perry Aggression Questionnaire, hardiness – Hardiness Survey (S. Maddi). The methods of mathematical statistics used in the research (descriptive statistics, correlation and regression analyzes) are implemented by means of the IBM SPSS Statistics 19 package.
Results. It has been proven that the resources of adolescents’ psychological safety in the educational environment are: values, psychological well-being, social intelligence, hardiness and a low level of aggressiveness. The state of psychological safety is influenced by such manifestations as conformity and following traditions, a positive image of the future, the experience of community with other people, the ability to understand and predict other people’s feelings and behavior, a sense of involvement in life events.
Discussion and Conclusion. The article is of interest for researchers of psychological safety problems in education, practical psychologists and specialists of the education system for the evidence of prevention programs and ensuring the safety of the educational environment and its participants.

Quality evaluation of metal surfaces treatment by wavelet analysis
Authors: Deineha L. , Berezhnoi А. , Kozlov V. , Sudakov V.
Published: September 2021

Purpose. Analyze the effectiveness of using wavelet analysis to assess the quality of metal surfaces. Investigate the possibility of using wavelet analysis in ultrasonic flaw detection. Determine the optimal wavelet families and their criteria for assessing the quality of metal surface processing.

Research methods. Orthogonal wavelets are considered: Daubechies wavelet, Simlet wavelet and Coiflet wavelet, which provide the possibility of performing a discrete wavelet transform procedure. The criteria influencing the effectiveness of ultrasonic signal filtering by methods using wavelet analysis are considered. Ultrasonic signals were filtered using wavelet functions.

Results. It has been determined that for successful signal filtering, the selected wavelet method must provide a discrete wavelet transformation and have a similarity in the wavelet function shape in the local features of the ultrasonic signals flaw detector. During the work, a rigid threshold for limiting the detail coefficients of wavelet analysis was chosen, as it is the best for filtering tasks. The filtering efficiency is confirmed by the relatively high signal to noise ratio, as well as by the fact that the shape of the pulse extracted from the defect remained almost unchanged.

Scientific novelty.  When using the Daubechies and Coiflet wavelets as basic functions, as a result of wavelet filtering, it was possible to increase the signal to noise ratio by 20 dB and confidently isolate the useful signal against the background noise, which indicates the prospects of using this kind of transformations in filtering problems.

Practical value. The obtained solutions can be used for implementation in signal filtering algorithms in digital processing units of automated non-destructive ultrasonic control systems.

Obtaining tube blanks from copper-nickel alloy МНЖ 5-1 when using a tool made of die steel adjustable austenitic transformation during operation
Authors: Sydorchuk O.
Published: September 2021

Purpose. Production of die tool from steel with regulation of austenitic transformation during operation to increase the level of service life during hot deformation of copper-nickel alloy.

Research methods. Metallographic, high-temperature X-ray phase and dilatometric analyzes of research steel.

Results. The mode of heat treatment (incomplete annealing) of steel 4Х3Н5М3Ф at a temperature of 750±20 °С, obtained by electroslag remelting, allowed to obtain a perlite-sorbitol structure at a hardness of33–34 HRC and allowed better machining by cutting the workpiece alloy. The proposed mode of final heat treatment (hardening 1030±10 °C and tempering 600±5 °C) of the investigated steel, makes it possible to heat the matrix during operation to a temperature of 600 °C.

Scientific novelty. The thermal stability of the tool for hot deformation can be significantly increased when using steel with adjustable austenitic transformation during operation. Such steel in the initial state has a ferrite base, and when heated to operating temperatures occurs from α-Fe to γ-Fe conversion and, subsequently, the austenitic structure is preserved throughout the period of high-temperature operation of the stamping tool. It is confirmed that the stamping tool made of steel 4Kh3N5М3F when pressing a copper-nickel alloy works in the temperature range corresponding to the austenitization process.

Practical value. Abbreviated technological operation, namely thermo-deformation processing (forging) of ingots obtained by electroslag remelting. Experimental-industrial tests of the die tool of steel 4Х3Н5М3Ф in the manufacture of tube blanks of Ø 67±0,1 mm from a copper-nickel alloy of the МНЖ 5-1 brand are carried out. As a result of research “Artemovsk plant for processing of non-ferrous metals and alloys” (Bakhmut, Donetsk region, Ukraine) at an operating temperature of 900–950 ° C, matrices made of steel 4Х3Н5М3Ф (without deformation-forging) showed stability in three times higher than the matrices from steel 3Х3М3Ф made at the enterprise.

Published: September 2021

Purpose. Analysis of methods of manufacturing centrifugal blades by 3D printing methods on the example of a modernized cooling system of the AI-450M engine of the Mi-2MSB helicopter.

Research methods: calculation method of finite elements, analytical.

Results. Studies have shown that the use of layer-by-layer printing technology of the centrifugal wheel of the cooling system provides the following opportunities and improvements:

- reduce the percentage of rejection of finished products by 8–9 times;

- reduce material consumption by 300–400 %;

- increase the speed of production, experiments and testing the manufacture of working elements through the development of new technologies for rapid production (rapid fabrication);

- easy printing of previously “impossible” geometry.

The analysis of possible types of manufacturing of  working centrifugal wheel and the calculated estimation of thermodynamic parameters in the course of step-by-step drawing of layers of metal is carried out. The problem of a large percentage of defects in the process of classical-mechanical milling of blades was solved by changing the type of production to additive one.

Scientific novelty. In today's world, the spread of CAD / CAM / CAE / PLM technologies and the accumulation of a wide library of materials open up a large number of new and more efficient, in terms of economy and quality, methods of manufacturing components and units. Following the example of such giants in the production of aircraft engines as Rolls-Royce Motor, General Electric and Pratt & Whitney, it is clear that the use and development of the latest methods of three-dimensional printing is appropriate.

Practical value. The obtained results are important in the further process of production and modernization ofMi-2 helicopter of all modifications with the latest engines, as well as for projects for the development of helicopter construction in Ukraine - МСБ-2 “Hope”, МСБ -6 “Otaman”, МСБ-8 and others. The ability to increase the efficiency of manufacturing the main working elements - blades allows you to reduce the cost of components, their further repair, operation. The most important factor is to increase reliability, as in the manufacture reduces the likelihood of defects, which will not be detected at the stages of intermediate and final control.
Passport to the oceans of the future: delivering marine energy with science linked to policy
Authors:   University of Aberdeen, Slater Anne-Michelle
Published: September 2021

In February 2021, a group from MASTS, Environmental Interactions of Marine Renewables (EIMR) and Marine Scotland began exploring options for a joint event on marine energy science and policy development. The original concept was to bridge the gap between events that each group would normally arrange ‘in person’ and the virtual world in which we were all currently existing. Encouraged by the online support and experience available from MASTS, a steering group decided to arrange a workshop. In order to straddle our interests, the starting point was the capacity of the North Sea to deliver renewable energy. We wanted to include emerging science and the timing of the review of Scotland’s National Marine Plan provided an excellent context. We sought to deliver a wide range of content but encourage participant conversation. We aimed for a range of speakers delivering 7-minute recorded talks. Talks included findings from funded research, ongoing projects, and some emerging thinking across the science policy interface for marine planning. Marine energy was interpreted in the widest of senses, but the main focus was on offshore wind in UK waters, with particular detail about Scotland.
ANÁLISE DO SERVIÇO DE ATENDIMENTO AO FREQÜENTADOR DE UMA ORGANIZAÇÃO VAREJISTA À LUZ DE UM MARCO REFERENCIAL DE ÉTICA NOS NEGÓCIOS
Authors: PIRES ÁLVARO MARCONI FERREIRA , PENA ROBERTO PATRUS MUNDIM
Published: September 2021

RESUMO Este artigo apresenta um estudo de caso que aborda a ética empresarial de uma organização varejista, do setor de shopping centers, no relacionamento com os seus freqüentadores (shoppers), via serviço de atendimento a clientes, por meio do construto teórico da Business Ethics, desenvolvido por Lozano (1999). Do ponto de vista metodológico, os dados foram coletados a partir de entrevista com gestores e aplicação de um questionário baseado nos indicadores 2003 ETHOS de responsabilidade social empresarial. Utilizou-se, também, da análise de conteúdo do código de ética, regimento interno, missão empresarial e manual de atendimento ao cliente. Outros dados foram coletados por meio de observação sistemática, levantamento de dados junto ao SAC, pesquisa no PROCON e simulações de demandas de serviço junto ao SAC. Concluímos que a políticas de relacionamento da empresa com os shoppers que recorrem ao Serviço de Atendimento ao Consumidor (SAC) estão revestidas da preocupação do grupo em melhorar a imagem da instituição junto a esse público. A empresa mostrou-se mais atenta à sua responsabilidade civil no sentido de resguardar-se de eventuais problemas de ordem jurídica nas suas relações com o shopper, do que com a afirmação de valores e sua inserção nos processos administrativos do setor da empresa pesquisado.

Authors: PEREZ GILBERTO , ZWICKER RONALDO
Published: September 2021

RESUMO No processo de seleção de fornecedores de serviços a avaliação de potenciais candidatos constitui tarefa das mais importantes, pois quando se avalia de forma inadequada podem-se comprometer os resultados e incorrer em custos não compatíveis. Em princípio, uma boa avaliação pode ser uma garantia de que a contratação será bem sucedida. Este trabalho verificou se as empresas adotam procedimentos diferenciados quando selecionam fornecedores de serviços de Tecnologia da informação (TI). Procurou-se identificar os procedimentos de avaliação e os critérios de seleção utilizados para a escolha de empresas fornecedoras de serviços de TI. Os resultados mostraram que, em função de peculiaridades das atividades de TI, o processo de seleção de fornecedores incorpora características específicas, sem contudo apresentar a sofisticação inicialmente esperada.

ABSTRACT Although patients with chronic obstructive pulmonary disease (COPD) benefit in many ways after participating in pulmonary rehabilitation programs, high dropout rates are still observed among participants. This study aims to analyze the adherence rate and perceived satisfaction in individuals with chronic obstructive pulmonary disease who underwent high-intensity physical training on land (LG) and in water (WG). This study is an additional analysis from a randomized controlled trial. In total, 36 subjects (51%) completed the intervention. All participants underwent six months of high-intensity endurance and strength training. Adherence was assessed by the proportion of patients who completed the training program. Perceived satisfaction was evaluated using a questionnaire composed of structured and semi-structured questions. The interviews were recorded, transcribed, and analyzed according to the criteria of our thematic analysis. The Shapiro-Wilk test was used to assess data normality, and dropout rates were compared using the chi-square test. Statistical significance was set at 5%. Regarding adherence, 59% of WG participants and 44% of LG participants completed the program, with no difference between the groups (p>0.05). Individuals from both groups were equally satisfied after six months of physical training (<90%); the therapist-patient relationship and treatment effectiveness being important factors for this perception. Qualitative analysis also showed that WG participants reported a more prominent improvement in their respiratory symptoms, leisure, sensation of pain, and sleep. In conclusion, patients with COPD were satisfied after six months of high-intensity physical training in water and on land, noting that water exercising promoted additional benefits compared to land exercising. There seems to be no superiority to any of the regimens (water or land) regarding the adherence to the training programs.

Published: September 2021

RESUMO A doença pulmonar obstrutiva crônica (DPOC) é altamente limitante, tanto nos aspectos físicos, quanto socioemocionais, causando dificuldades significativas no cotidiano dos pacientes. Além de afetar os pacientes, a DPOC também influência na vida dos familiares e amigos próximos, pois deles vem a rede de apoio de que os pacientes necessitam. O objetivo deste artigo é avaliar a funcionalidade da família no cotidiano de pacientes acometidos por DPOC. É um estudo transversal que avaliou a funcionalidade de família de pacientes com DPOC em diferentes estágios da doença e que realizam Programa Reabilitação Cardiorrespiratória (PRC). Utilizou-se o instrumento APGAR de Família, sendo este, um acrônimo caracterizado por A = (Adaptation/Adaptação), P = (Partnership/Companheirismo), G = (Grow/Desenvolvimento), A = (Affection/Afetividade), R = (Resolve/Capacidade resolutiva), composto por 5 questões avaliadas em “sempre”, “algumas vezes” e “nunca”, o que somados resultam em “elevada disfunção familiar”, moderada disfunção familiar” e “boa funcionalidade familiar”. Foram avaliados 21 pacientes DPOC [sexo masculino (n=11; 52,3%); idade média 66,3±10 anos], com estadiamento entre moderado a muito severo. Através do APGAR da Família identificamos 2 pacientes com elevada disfunção familiar; 2 pacientes com moderada disfunção familiar; 17 pacientes com boa funcionalidade familiar. Dos que relataram elevada e moderada disfunção familiar, os acrômios mais comprometidos foram “companheirismo”, “afetividade” e “desenvolvimentos”. O grau de obstrução das vias áreas associou-se moderada e positivamente com a funcionalidade da família (r = 0,697; p = 0,004). Pacientes com DPOC participantes do PRC apresentaram boa funcionalidade familiar no seu cotidiano e a gravidade da doença esteve associada a esta funcionalidade. Pacientes que apresentaram maior disfunção familiar relataram falta de “companheirismo”, “afetividade” e “desenvolvimentos”.

Published: September 2021

RESUMO A doença renal crônica (DRC) é definida como dano à função renal. Doentes renais crônicos atingem alta prevalência de morte por eventos cardiovasculares antes dos estágios finais, sendo maior a mortalidade em estágio dialítico, em que é evidenciado um desequilíbrio autonômico. Objetivamos avaliar a modulação simpatovagal de pacientes com DRC em tratamento de hemodiálise ambulatorial. Foram avaliados 23 pacientes, divididos em: Grupo DRC com DRC no estágio 5D (DRC-5D) em tratamento regular de hemodiálise ambulatorial; Grupo-controle com indivíduos saudáveis. A variabilidade da frequência cardíaca (VFC) foi coletada por um cardiofrequencímetro e analisada por índices lineares do domínio do tempo e do domínio da frequência. 14 pacientes no Grupo DRC com média de idade 48±16; e 9 pacientes saudáveis no Grupo-controle com média de idade 64±5. Nos resultados pelo domínio de tempo, o Grupo DRC mostrou valores significativamente maiores da frequência cardíaca (FC) comparado ao Grupo-controle (83,49±13,09 bpm vs. 67,88±9,43 bpm). Todavia, os índices média dos intervalos R-R (735,82±121,54 ms vs. 898,94±123,58 ms), RMSSD (11,75±11,86 ms vs. 20,03±6,80 ms), SDNN (17,06±9,81ms vs. 28,42±7,62 ms) do Grupo DRC mostraram valores significativamente menores comparados aos do Grupo-controle, respectivamente. Nos resultados pelo domínio da frequência, o Grupo DRC mostrou valores significativamente menores em comparação ao Grupo-controle nos índices BFab (129,7±184,3 ms vs. 262,31±168,15 ms) e AFab (82,70±227,66 ms vs. 180,77±119,85 ms). Pacientes com DRC em hemodiálise apresentaram redução da modulação parassimpática quando comparados com indivíduos saudáveis, sugerindo prejuízo do balanço simpatovagal e, consequente, disfunção autonômica cardíaca.

Published: September 2021

RESUMO O objetivo do estudo é descrever o perfil de três grupos de mulheres: aparentemente saudáveis (não doentes-ND); com doenças cardiovasculares (DC); e com doenças respiratórias (DR) crônicas. A pesquisa comparou esses grupos conforme variáveis sociodemográficas (faixa etária, escolaridade, etnia e renda familiar) e dados sobre qualidade de vida (QV), segundo domínios: físico, psicológico, relações sociais e meio ambiente. Este estudo é caracterizado como quantitativo, analítico, observacional e transversal de base populacional, com informações extraídas do Inquérito de Saúde da Mulher, realizado na cidade de Uberaba-MG. Foram entrevistadas 1.387 mulheres, com o objetivo de coletar informações sobre DC, DR, idade, escolaridade, etnia e renda familiar. A QV foi estudada por meio do WHOQOL - Bref, segundo os quatro domínios. Foi realizado levantamento estatístico, descritivo e inferencial. Identificou-se que o grupo com DC é formado por mulheres com idade a partir de 50 anos e baixa escolaridade, em oposição ao grupo de mulheres com DR, que são mais jovens e possuem escolaridade superior. Quanto à QV, as mulheres com DC (31,65%) apresentaram níveis inferiores em relação às mulheres com DR (19,10%), nos domínios: físico (50,6;54,0;<0,0001), psicológico (55,1;58,7;<0,0001), relações sociais (75,8;77,2;0,0055) e meio ambiente (41,7;43,0;0,0173), valores em média. Portanto, o domínio de QV que obteve menor pontuação para todos os grupos foi o meio ambiente e as mulheres com DC apresentaram valores mais baixos, estatisticamente significativos, para todas as categorias.

Published: September 2021

HackLearn is a scenario-based hacking simulation game for teaching cybersecurity concepts while providing hands-on hacking experiences to the learners. HackLearn design is based on the COFELET framework, which assimilates modern learning theories, well-known cybersecurity standards, and built-in scaffolding and assessment features. Aiming at evaluating the user experience perceived by HackLearn’s users, we describe the process of adopting it in a real educational environment based on the didactic framework for simulation games. Additionally, we present the evaluation methodology elaborated, based on the serious games’ quality characteristics framework. We discuss the evaluation results which indicate that HackLearn is engaging, motivating, usable and effective in teaching cybersecurity concepts and hacking strategies and techniques. The evaluation results revealed the HackLearn’s aspects that can be improved such as the scaffolding feature and the communication mechanism with the game’s back-end facility. The presented work validates and finalizes prior work elaborated on the COFELET framework (e.g., COFELET ontology and the COFELET games life-cycle), whereas it provides directions for future work in the development and evaluation of cybersecurity serious games.

THE CONSTITUTIONAL DUTY TO ENGAGE IN COLLECTIVE BARGAINING
Authors: Angela Patricia Molusi
Published: September 2021

The law regarding collective bargaining in South Africa has been interpreted in two ways; the Labour Relations Act (LRA) refers to a duty to bargain collectively, while the Constitution refers to a right to engage in collective bargaining. These two interpretations have been subjected to judicial criticism (SANDU v Minister of Defence 2003 3 SA 239 (T) I; SANDU v Minister of Defence 2004 4 SA 10 (T) II; and Minister of Defence v SANDU 2007 1 SA 422 (SCA) III (hereafter “SANDU I, II and III”)). These cases are relevant in terms of the courts’ interpretation of collective bargaining as a duty or freedom. They are currently the main cases dealing with this issue in South Africa. This has created doubt as to whether the distinction provides an acceptable basis to use the terms interchangeably, both by the courts as well as those involved in collective bargaining. The purpose of this paper is firstly to sketch the landscape of South Africa’scollective bargaining jurisprudence, touching on the current legislation and secondly to give an overview of why collective bargaining is a necessary tool to balance power in the workplace. I shall examine the discourse as to whether the term “collective bargaining” creates a duty to participate (which can mean compelled) in collective bargaining on the part of the employer, as opposed to a right to engage in collective bargaining (which is voluntary). Lastly, the author will attempt to show the thread of how the courts have answered the question in case law.
NOTIFICATION OF ACCEPTANCE AND THE CONCLUSION OF A CONTRACT Withok Small Farms (Pty) Ltd v Amber Sunrise Properties 5 (Pty) Ltd 2009 2 SA 504 (SCA)
Authors: C-J Pretorius  , R Ismail
Published: September 2021

It is a long-standing principle in our law that generally a contract is only concluded when the offeree notifies the offeror of acceptance and, consequently no contract arises if there is no notification of acceptance. This general rule is derived from the will theory, which requires not only coinciding expressions of intention (usually styled “offer” and “acceptance”), but also knowledge of the offeree’s acceptance by the offeror so that conscious agreement exists between the parties (consensus ad idem). However, the offeror may expressly or impliedly dispense with this requirement, since the offeror may prescribe the method by which his offer may be accepted by the offeree. It also seems that where there is doubt, “the presumption that the contract will be completed when the offeror comes to hear of the offeree’s acceptance, should prevail”. In the recent matter of Withok Small Farms (Pty) Ltd v Amber Sunrise Properties 5 (Pty) Ltd (2009 2 SA 504 (SCA)) the Supreme Court of Appeal had to decide the very issue of whether the offeror had dispensed with notification of acceptance by the offeree. The context in which the court had to decide this issue and the approach adopted raise some interesting issues for discussion.
PREDATORY PRICING: SINGLE- FIRM DOMINANCE, EXCLUSIONARY ABUSE AND PREDATORY PRICES (PART 2)
Authors: Jan Louis van Tonder
Published: September 2021

Important pronouncements of legal principle were recently made by the Competition Appeal Court and Constitutional Court on the determination of predatory pricing under section 8 of the Competition Act 89 of 1998. These pronouncements must now be seen in the context of the subsequent commencement of certain provisions of the Competition Amendment Act 18 of 2018, which affect predatory pricing cases under section 8 of the Act. In light of these developments, the main aim of this series of three articles is to evaluate the law relating to the economic concept of predatory pricing under the Competition Act. In this context, the main constituent elements of a predatory pricing case – namely dominance, identifying an exclusionary abuse, and predatory prices – are discussed in three parts. Part 1 has critically evaluated the law on the determination of single-firm dominance under section 7 of the Competition Act. Part 2 starts to focus on the abuse analysis and discusses the basic forms of abuse, the meaning of abuse, tests that have been developed to identify exclusionary abuse, the criticism of the traditional theory of predatory pricing, the main strategic economic theories of predatory pricing and non-pricing theories of predation. Part 3 then specifically deals with the law of predatory prices under section 8(c) and (d)(iv) of the Competition Act. Pursuant to section 1(3) of the Competition Act, when interpreting or applying the Competition Act, appropriate foreign and international law may be considered. This is complementary to section 1(2)(a), which directs that the Competition Act must be interpreted in a manner that is consistent with the Constitution and gives effect to the purposes set out in section 2. In light hereof, where appropriate, the South African position is mainly compared with the position in the European Union and the United States.
COMMISSIONS OF INQUIRY AS A RESPONSE TO CRISIS: THE ROLE OF THE JALI COMMISSION IN CREATING PUBLIC AWARENESS OF CORRUPTION (PART 2)
Authors: Stephen Allister Peté
Published: September 2021

When the government of a liberal constitutional democracy is confronted by some or other existential crisis that threatens a major institution of state or the very foundations of the democracy itself, it will often appoint a high-level judicial commission of inquiry as part of its response to the crisis. South Africa is no exception to this tendency, as is evidenced in recent years by the appointment of no fewer than four such commissions in response to a series of crises related to ongoing corruption within state institutions – commonly referred to by ordinary South Africans as “state capture”. This has raised questions as to the alleged benefits of such commissions when viewed in relation to their considerable costs. This article seeks to contribute to this general debate by focusing on one of the purported benefits of such commissions that may be somewhat under appreciated. This is the creation of public awareness, during the life of the commission itself, about the nature and extent of the particular grave threat that confronts the society in question. It is contended that, mediated by a free and vibrant press, the public narrative that emerges during the operation of a commission of inquiry may serve to make a liberal democratic society more resilient in the face of threats to that society’s continued existence. This article seeks to support this contention by focusing on an important precursor to the more recent commissions of inquiry on corruption in South Africa – that is, the Jali Commission of Inquiry into corruption within the South African penal system, which sat in the early years of the new millennium. By analysing the many articles and reports that appeared in a range of South African newspapers during the initial hearings of the Jali Commission, this article documents the emergence of an important public narrative on corruption within South Africa’s prisons, and reflects upon the ultimate significance. This article is divided into two parts: the first part deals with the initial hearings of the Jali Commission in KwaZulu-Natal, and the second part with subsequent hearings in the Free State.
THE PRINCIPLE OF LEGALITY AND THE REQUIREMENTS OF LAWFULNESS AND PROCEDURAL RATIONALITY Law Society of South Africa v President of the RSA (2019 (3) SA 30 (CC))

Apart from conferring a wide range of powers on the President, the Constitution also regulates the manner in which the President may exercise these powers. One of the ways in which the Constitution does this is by imposing an obligation on the President to exercise his or her powers in accordance with the principle of legality, which is an incident of the rule of law. A necessary consequence of this requirement is that a decision of the President may be reviewed and set aside on the grounds that it infringes the principle of legality.From its relatively modest beginnings in Fedsure Life Insurance v Greater Johannesburg Transitional Metropolitan Council (1999 (1) SA 374 (CC)) – where the Constitutional Court held that the exercise of public power is only legitimate when it is lawful – the principle of legality has expanded in leaps and bounds over the past 21 years; today, it encompasses several other grounds of review, including lawfulness, rationality, undue delay and vagueness.Of all of these broad grounds of review, substantive rationality has received the most attention from the courts and today encompasses several other grounds of review itself, such as procedural fairness, procedural rationality, relevant and irrelevant considerations (Democratic Alliance), non-jurisdictional mistake of fact, and, on occasion, the giving of reasons.Unfortunately, the development of the principle of legality has not been all plain sailing, and the rationality jurisprudence of the Constitutional Court has given rise to complex and difficult questions. This is particularly the case when it comes to procedural fairness and procedural rationality. It is not entirely clear what the difference between these two requirements is and in what circumstances the one should be applied rather than the other. The court attempted to address some of these questions in Law Society of South Africa v President of the Republic of South Africa (2019 (3) SA 30 (CC)) (Law Society). The purpose of this note is to discuss this case critically.

Introduction. The development of new wear-resistant materials obtained by the method of self-propagating high-temperature synthesis (SHS) is an urgent problem in materials science. The SHS method is most widely used in the field of creating new powder materials. Much less attention has been paid to the production of monolithic non-porous composites. For monolithic composites, it is very important to identify the role of the metal matrix and phase transformations in the process of secondary structure formation after the completion of the synthesis process when the obtained material is cooled. The aim of this work was to carry out a comparative analysis of the structure and properties of SHS composites of the Fe-Ti-C-B, Fe-Ni-Ti-C-B, Fe-Ni-Cr-Ti-C-B, and Cu-TiC-B systems. Materials and research methods. Composites were obtained from powder mixtures consisting of thermoreactive components Ti, C, and B, as well as matrix Fe, Fe-Ni, Fe-Ni-Cr, and Cu. The initial powders were thoroughly mixed, loaded into a steel tube container, and the powder mixture was preliminary compacted. Then, the workpieces were heated in an electric furnace to the temperature of the onset of autoignition. After completion of the SHS, the workpieces were deformed with a force of 250 MPa in a hydraulic press at a temperature not lower than 1000 ° C. Samples were cut from the obtained sandwich plates for microstructural studies, density determination, hardness measurements, transverse bending tests and abrasive wear resistance tests. Results and discussion. All investigated composites were characterized by an uneven distribution of strengthening particles TiC and TiB2 over the volume. The use of the Fe-Ni matrix led to the formation of regions with the γ-Fe + Fe2B eutectic structure in the composite and an additional strengthening phase Ni3Ti. The use of Fe-Ni-Cr metal-matrix components led to the formation of two solid solutions in the matrix - austenite and ferrite, and Cr23C6 particles were formed along the boundaries of austenite grains. The maximum transverse bending strength was shown by SHS composites of the Fe-Ti-C-B and Cu-Ti-C-B systems with a matrix of FCC solid solutions. All composites had a hardness of 66 -72 HRC and showed the same abrasion resistance.

The article analyzes certain factors (external and internal) that affect the preservation of the national and cultural identity of Ukrainians living outside Ukraine. The key internal factor is national self-identification. Among the external factors are the following: ideological factor, value security, the religious factor, the factor of historical bias in foreign and Ukrainian media, the factor of manipulation of consciousness, the factor of aesthetic and value orientation, and others.
The need for more resolute opposition to the political and ideological influences of Russia, which invaded the territory of Ukraine and unleashed a hybrid war with its people, is highlighted. The authors of the article pay attention to the problems of the ontology of war and peace in the context of Ukraine‟s experience in counteracting the Russian-Ukrainian war, which became a long-term factor of destructive influences on Ukrainian socio-economic, political, cultural, educational, and scientific activities.
Attention is drawn to the fact that the aggressive actions of the Russian Federation cause devastating consequences not only for Ukraine but also for the system of world order and international security, the main factor destabilizing the security environment in the regional environment of Ukraine.
In the article, the ways of preserving the national and cultural identity of the Ukrainian diaspora are revealed through strategic and security paradigms, with the inclusion of multilevel interaction of cognitive meanings. Particular attention is paid to the role of national-cultural identity and analysis of the cognitive dimension in hybrid conflicts.
