Published: December 2022

Societal impact reflects the changes that transform the society which affect the well-being of individuals and their families. This study aimed to understand the perceived societal impact of the fourth industrial revolution in South Africa. The investigation used an exploratory mixed research method, with six experts in round table discussion (focus group) and a survey questionnaire with 1,1105 responses. The findings of the study confirm the existential relational proposition that the fourth industrial revolution has a societal impact in South Africa. It is influenced by socio-demographic (province, age) and socio-economic (education and employment) factors. The findings also revealed that the perceived highest impact of fourth industrial revolution’s will be on improved re-industrialisation (RII = 68.6 percent), increase in work mobility (RII = 68.1 percent) and improved service delivery (65.1 percent). Regarding benefits, if correctly leveraged, these new disruptive technologies create a significant opportunity to leapfrog the advancements made in the previous industrial revolutions and help develop society. However, this might widen socio-economic gaps further, especially if there is no action to change the status quo of the highly unequal society in South Africa.

Authors: Mlambo Courage
Published: December 2022

This paper is an overview of workers’ rights in Zimbabwe focusing on the abuse, exploitation of workers and the brutal attitudes displayed toward mine workers and trade unions officials by mining companies and government authorities. Zimbabwe’s mining sector plays a major role in Zimbabwe’s export economy. However, Zimbabwe’s mining sector, like many other mining sectors in the developing world, has workers’ right issues. Considerable attention has been given to the labour legislation by the government of Zimbabwe but there are still serious violations of workers’ rights in Zimbabwe. Mining firms involved in extracting the mineral wealth of the country are benefiting at the expense of workers. They are operating with little regard for the well-being of its employees. In light of this, the present study highlights and synthesizes workers’ rights issues in the Zimbabwe mining sector. The study also offers practical recommendations that could address the problems that mining workers are currently facing in Zimbabwe

Authors: Kidane Abay , Xuefeng Zhao
Published: December 2022

Behavior maintenance for organizational change is the continuous behavior performance following an initial intentional change. This research examines the importance of factors that influence behavioral maintenance for organizational change. This study proposes a research model incorporating self-determination, regular-fit, self-concept, and habit theories to identify potential influencing factors of behavioral maintenance for organizational change in Ethiopia and quantify the importance level of these factors using ML techniques. A survey study was carried out in Addis Ababa, Ethiopia, with 310 valid responses. The comparison of five different ML techniques shows that Naive Bayes (GaussianNB) outperforms the other classification model.  Naive Bayes (GaussianNB) model-based feature importance analysis shows that perceived competency, perceived enjoyment, and perceived autonomy are the most prominent contributor to behavioral maintenance for organizational change. The results confirmed that the quality of individuals' motivation affects the extent to which individuals will engage in, and persist with, behaviors.

Published: December 2022

Entrepreneurship is an innovative and creative process that can add value to products, create job opportunities, raise productivity, revitalize, and diversify markets, improve social welfare, and, more broadly, develop the economy. Entrepreneurship education encourages the founding of new businesses by students and alums and equips them with critical decision-making skills that enhance the success of graduates in the job market. That is why we seek to develop better entrepreneurs. Part of that is raising their intentions to start a business; another is making their intentions more realistic. To do both requires a deeper, richer understanding, and analysis of an entrepreneurial implementation intention in vocational education students is essential. In this study, researchers want to know what variables affect Entrepreneurial Implementation Intention in vocational education students at Universitas Padjadjaran. The results of this study found that Entrepreneurial Knowledge affects the main determinant of this research to encourage the increase of Entrepreneurial Implementation Intention.

Published: December 2022

A produção agrícola brasileira é considerada uma das maiores do mundo, devido ao seu tamanho territorial e o seu potencial em produzir grãos. Trichoderma spp. é um dos fungos mais pesquisados no Brasil, pois tem ocorrência natural em praticamente todos os tipos de solos, e por possuir uma versatilidade de ação próprias, podendo atuar como promotor de crescimento vegetal. Diante disso, objetivou-se avaliar a eficiência da inoculação do isolado UFT-201 como promotor de crescimento nas culturas do milho e arroz em casa de vegetação. O experimento foi conduzido na estação experimental da Universidade Federal do Tocantins (UFT) - Campus Universitário de Gurupi. Os tratamentos consistiram em cinco doses do inoculante (0, 3, 6, 9, 12 g kg-1), misturados à semente no momento da semeadura. A cepa utilizada foi obtida no Laboratório de Agromicrobiologia Aplicada e Biotecnologia da Universidade Federal do Tocantins. O inoculante utilizado foi preparado em fermentação sólida utilizando arroz como substrato. Foram avaliadas características morfológicas (altura, volume de raiz, massa seca) e fisiológicas (pigmentos fotossintéticos e trocas gasosas) aos 30 e 45 dias após a semeadura. O fungo Trichoderma asperellum UFT-201 inoculado via semente aumentou o volume radicular e a biomassa das plantas de milho e arroz na dose de 6 g kg-1 de sementes. O ganho em biomassa das culturas está relacionado com alterações fisiológicas nas culturas promovido pela inoculação e doses acima de 12 g kg-1 de sementes podem reduzir o desenvolvimento inicial das culturas, principalmente para arroz.

Authors: Haryono Sony , Susanty Betty , F Toyfur Mona
Published: December 2022

Today, the increasing electricity demand will increase the number of electricity infrastructure developments in Indonesia. One of the electricity infrastructures is the transmission line, which transmits electricity from the power plant to the consumer. On the other hand, the limited funds owned by the owner and the various benefits that will be obtained have made a turnkey contract widely used. However, transmission line projects with a turnkey contract have just been implemented in Indonesia, so many studies have yet to be done on the risks during construction. As a result, most transmission line projects in Indonesia use traditional/non-turnkey contracts. This study aimed to identify and analyze risks that occur in transmission line projects with a turnkey contract during the construction period. This study was conducted quantitatively; risk identification was obtained from various risk variables in previous studies. The risk variables were then measured for the level of risk using a probability and impact analysis. Finally, a questionnaire was distributed to respondents who were directly involved in the construction period of the transmission line projects with a turnkey contract. The results of this study indicate the risks that occur in the transmission project with a turnkey contract. There are two risks with the highest level of risk that affect the completion time of the work, namely (i) the contractor is in financial trouble and (ii) the contractor's financial capacity is not good. It is hoped that contractors or other stakeholders can use the results of this study to mitigate before the work starts so that the project can be completed within the agreed time.

Published: December 2022

The need to regulate the non-exhaust particulate emissions from vehicles has been discussed worldwide due to the toxicity to the human body as well as the atmosphere. In-depth studies have been conducted on precise analysis of the non-exhaust particulates, in particular, accurate measurement of tire-brake-road wear particles, and their proportion in the atmosphere. In this study, the influence of tire and road wear particles (TRWP) on particulate matter (PM) in the atmosphere was investigated through tire and PM samples. PM samples were collected from the atmosphere using a high-volume sampler equipped with a quartz filter. Additionally, polycyclic aromatic hydrocarbons (PAHs) and heavy metals in tire rubber were analyzed as markers by pyrolysis-gas chromatography/mass spectrometry (GC/MS), GC/MS, and inductively coupled plasma/mass spectrometry (ICP/MS). More vinylcyclohexene was detected than dipentene in the markers measured in the samples of tires equipped with vehicles driving on the road with the high-volume sampler installed, while more dipentene was detected in total suspended particles (TSP) samples. Among the PAHs measured in tire samples, pyrene exhibited the highest concentration. In TSP samples, benzo(b)fluoranthene showed the highest concentration. Among the heavy metals, zinc exhibited the highest concentration in all tire samples and calcium in TSP samples.
Community-Based Approaches in the Construction, Ownership, and Management of Water Infrastructures and the Development of Socio-Political Complexity Among the Chagga, Kilimanjaro, Tanzania
Authors: Silayo Valence Meriki , Pikirayi Innocent
Published: December 2022

Since the second half of the second millennium AD, water management among the Chagga people of Kilimanjaro in Tanzania has involved community collaboration in the construction, ownership and management of water infrastructure. Chagga settlement on the lower slopes of Kilimanjaro transformed the landscape significantly to reflect an agrarian society characterised by decentralised forms of socio-political and economic organisation. Such organization involved conception, construction, and post-construction management of water distribution systems, constituting high-level socio-political complexity. The study employs ethnography, archaeological surveys and GIS to document water infrastructures on the lower slopes of Kilimanjaro. We conclude that community collaboration was key in management of the water infrastructure and by extension, agriculture, which sustained Chagga and chiefdoms for centuries.

Extracellular vesicles (EVs), produced during viral infections, are of emerging interest in understanding infectious processes and host-pathogen interactions. EVs and exosomes in particular have the natural ability to transport nucleic acids, proteins, and other components of cellular or viral origin. Thus, they participate in intercellular communication, immune responses, infectious and pathophysiological processes. Some viruses are known to hijack the cell production and content of EVs for their benefit. Here, we investigated whether two pathogenic flaviviruses i.e. Zika Virus (ZIKV) and Dengue virus (DENV2) could have an impact on the features of EVs. Analysis of EVs produced by infected cells allowed us to identify that the non-structural protein 1 (NS1), described as a viral toxin, was associated with exosomes. This observation could be confirmed under conditions of overexpression of recombinant NS1 from each flavivirus. Using different isolation methods (i.e. exosome isolation kit, size exclusion chromatography, Polyethylene Glycol enrichment, and ELISA capture), we showed that NS1 was present as a dimer at the surface of excreted exosomes and that this association could occur in the extracellular compartment. This finding could be of major importance in a physiological context. Indeed, this capacity of NS1 to address EVs and its implication in the pathophysiology during Dengue or Zika diseases should be explored. Furthermore, exosomes that have demonstrated a natural capacity to vectorize NS1 could serve as useful tools for vaccine development.

Background: With the trend of intelligent display, the interface design of in-vehicle HUD is an expanding research field; Methods: To solve the subjectivity and uncertainty in the optimization of HUD interface design schemes, this paper proposed a hybrid scheme evaluation and optimization method based on entropy weight and VIKOR. The entropy weight method was used to reduce the subjectivity the decision-maker's weighting and obtain the objective weight of each indicator; The VIKOR method was used to obtain the best ranking of alternative schemes, and then the optimal interface design scheme was selected; Results: The evaluation of in-vehicle HUD interface design schemes were taken as an example for verification and calculation. The results showed that this method considers the subjectivity and uncertainty of the decision-making process in the optimization of design scheme, which can effectively improve the objectivity and accuracy of the evaluation results, and provide a reference for designers to optimize interface design schemes.
Delicate Comparison of the Central and Non-central Lyapunov Ratios with Applications to the Berry–Esseen Inequality for Compound Poisson Distributions
Authors: Makarenko Vladimir , Shevtsova Irina
Published: December 2022

For each $t\in(-1,1)$, exact values of the least upper bounds $$ H(t)=\sup_{\E X=t,\,\E X^2=1} \frac{\E\abs{X}^3}{\E \abs{X-t}^3},\quad \sup_{\E X=t,\,\E X^2=1} \frac{L_1(X)}{L_1(X-t)} $$ are obtained, where $L_1(X)=\E|X|^3/(\E X^2)^{3/2}$ is the non-cental Lyapunov ratio. It is demonstrated that these values are attained only at two-point distributions. As a corollary, S.\,Shorgin's conjecture is proved that states that the exact value is $$ \sup\frac{L_1(X)}{L_1(X-\E X)}= \frac{\sqrt{17 + 7\sqrt7}}{4} = 1.4899\ldots, $$ where the supremum is taken over all non-degenerate distributions of the random variable $X$ with the finite third moment. Also, in terms of the central Lyapunov ratio $L_1(X-\E X)$, an analog of the Berry--Esseen inequality is proved for Poisson random sums of independent identically distributed random variables with the constant $$ 0.3031\cdot H\left(\frac{\E X}{\sqrt{\E X^2}}\right) \left(1-\frac{(\E X)^2}{\E X^2}\right)^{3/2} \le 0.3031\cdot \frac{\sqrt{17 + 7\sqrt7}}{4}<0.4517.$$ where $\Law(X)$ is the common distribution of the summands.

Published: December 2022

A differential bundle function (DBF) is a situation in which examinees who are of the same ability but are from different groups are required to answer groups of items differently. DBF undermines the validity of the instrument if inadequately considered. The study examines the dimensionality of the 2017 NECO Mathematics items, determines the effect of DBF on 2017 Mathematics items concerning sex, and investigates the effect of DBF on 2017 Mathematics items concerning school ownership. This study explores Exploratory Structural Equation Modelling (ESEM), which permits the cross-loading of items that are not allowed in other models. The ex-post facto research design was adopted using secondary data, while six bundles were generated via the specification table. The population for the study comprised all 1,034,629 Senior School three students. A total of 815,104 students were selected using the simple random technique. The instrument for the study was 2017 NECO Mathematics paper three with a Cronbach's alpha of 0.82, and data were analysed using Mplus 7.4. The results revealed that the 2017 NECO Mathematics is multidimensional and items in the bundles possess construct validity as they functioned differentially to examinees' sex and school type. We recommend ESEM has a better approach to examining DBF on 2017 NECO Mathematics test items.

Published: December 2022

The development of a predictive hepatotoxicity model is highly warranted, as the hepatotoxicity risk goes undetectable in nonclinical studies. Cholestatic drug induced liver injury (DILI) is a condition in which bile acids are not normally excreted into the capillary bile canaliculi and are accumulated in hepatocytes, caused by the inhibition of bile salt export pump (BSEP), a transporter that is mainly associated with excretion of bile acids. Although laboratory animals are used as predicting model, the use of human-derived cells is required due to species differences. Moreover, primary human hepatocytes (PHHs) show rapid loss of function, and difficulties in forming bile canaliculi in vitro. Therefore, we aimed to develop an in vitro culture method for efficient formation of bile canaliculi and the function of BSEP in PHHs. Here, PHHs were cultured from 1 h after thawing to day 2 with Z-VAD-FMK, a total caspase inhibitor, and RevitaCell™ supplement, an irreversible Rho -associated coiled-coil forming kinase (ROCK) inhibitor, in combination with RM-101. The PHHs were able to form bile canaliculi and show BSEP function on day 6 of culture. Therefore, these cultured PHHs may serve as an accurate predicting model for cholestatic DILI.

We aim to synthesize hydroxyethyl starch (HES) 200/0.5 -loaded bovine serum albumin nanoparticles (HBNs) and investigate the compatibility and binding mechanism in simulated physiological environments. Herein, to elucidate the morphology, biocompatibility, and formation mechanism of HBNs, techniques such as scanning electron microscopy, hemolysis test, fluorescence, and circular dichroism spectroscopy were applied. The thermodynamic parameters at body temperature (ΔG=-2.35×104 J·mol− 1, ΔS°=-26.7 J·mol− 1·K− 1, and ΔH°=-3.20×104 J·mol− 1) showed a 1:1 binding stoichiometry, which was governed by hydrogen bonds and van der Waals interactions. Moreover, the conformational analysis revealed that the microenvironment of fluorophores was changed with the adaptational protein secondary structural changes. Energy transfer occurred from the fluorophores to HES with a high possibility. All these results provided accurate and complete primary data for clarifying the binding mechanisms of HES with BSA, which helps understand its pharmaceutical effects in blood.

Проведен анализ физико-механических свойств спортивно-беговых пластиковых лыж, изготовленных с использованием препрегов на основе различных армирующих наполнителей. Армирование полимерных композиционных материалов осуществляется волокнистыми наполнителями, включающими большое число разнообразных текстильных структур, изготавливаемых на основе волокон и нитей (пряжи, химических нитей) и/или бумажных полотен. В качестве армирующих наполнителей были выбраны отечественные широко распространенные материалы: директ-ровинг стеклянный, базальтовое и полиэфирное волокно. Широкий набор различных волокнистых структур объясняется необходимостью получения препрегов с различными механическими, технологическими и функциональными свойствами, которые будут иметь определяющие значения для конечного продукта. Цель данного исследования – определить влияние различных АН на эксплуатационные свойства лыж. В качестве определяющих эксплуатационных свойств изучены: нагрузка распрямления (индекс жесткости по Фишеру), жесткость средней части лыжи, высота остаточного прогиба, постоянная жесткости передней (задней) частей лыжи. На примере разработанного отечественного эпоксидного связующего, полученных на его основе препрегов с использованием различных армирующих наполнителей (стеклянных, базальтовых и полиэфирных) показано, что физико-механические свойства конечного продукта (лыж) напрямую зависят от природы наполнителя.

The analysis of the physical and mechanical properties of the sport-running plastic skis made with the use of prepregs based on different reinforcing fillers has been carried out. Reinforcement of polymeric composite materials is carried out by fiber fillers, which include a large number of various textile structures made on the basis of fibers and yarns (yarn, chemical threads) and/or paper webs. Domestic widespread materials were chosen as reinforcing fillers: direct glass roving, basalt and polyester fibers. The wide range of different fiber structures is explained by the need to obtain prepregs with different mechanical, technological and functional properties, which will have decisive values for the final product. The purpose of this study is to determine the influence of different NAs on the performance properties of skis. The following performance properties were studied as determinants: the straightening load (Fischer stiffness index), the stiffness of the ski middle part, the height of the residual deflection, the stiffness constant of the ski front (rear) parts . On the example of the developed domestic epoxy binder and prepregs obtained on its basis using different reinforcing fillers (glass, basalt and polyester), it is shown that the physical and mechanical properties of the final product (skis) directly depend on the nature of the filler.
