Authors: Syakirotin Muthiah , Karyani Tuti , Noor Trisna Insan
Published: January 2025

The Covid-19 pandemic has had an impact on changes in community economic activity, resulting in an impetus for increasing poverty rates (BPS, 2020). This happens because of the community's space for movement so that it has an impact on the community's ability to obtain safe and sufficient food. Based on the 2020 Food Security Index, most districts in West Java are in a very resilient status. The status of food security at the provincial or city/district scale does not always guarantee that every individual is food secure because each region has different characteristics. Therefore, it is necessary to study the model of the influence of the proportion of poverty and the proportion of the population infected with Covid-19 on food security in Bandung Regency to the village level. This study aims to model the effect of the proportion of poverty and the proportion of the population infected with Covid-19 on the resilience of Bandung Regency using Geographically Weight Regression (GWR), which is a geographically weighted regression. Based on the analysis of the model of the effect of the proportion of the population infected with Covid-19 and poverty on food security in Bandung Regency, there are 280 different GWR models. In the GWR model the effect of the proportion of the population infected with Covid-19 on food security, there are 40 villages in red (high influence) and 15 villages in green (low influence). The village that has the highest influence on the proportion of the population infected with Covid-19 is Nengkelan Village with a coefficient of 21.02323822 and Laksana Village has the lowest effect with a coefficient of -18.760392. While the GWR model of the effect of poverty on food security is found in 9 villages in red color and 4 villages in green color. The village with the highest influence is Cipelah Village with a coefficient of 0.661185245 while the village with the lowest influence is Sukaresmi Village with a coefficient of -2.667401414.

Tobacco shreds are one way of processing tobacco plants. Tobacco farming in Panarukan District is owned by the community. Kilensari Village is one of the tobacco producing areas in Panarukan District. Although the price of tobacco changes every planting season, high market demand encourages farmers to develop the tobacco industry. The high interest of farmers in cultivating tobacco in Kilensari Village has certainly given rise to businesses engaged in this sector, one of which is the processing of tobacco water shoots into Rajang tobacco. This business was founded by Mr. Kafi since the last 20 years with a slashing system to obtain raw materials from surrounding farmers. The purpose of this study was to determine the added value obtained from processing water shoots into sliced tobacco. This study was designed with a qualitative design and used a case study technique. Data were analyzed using the Hayami value-added method and described with quantitative and qualitative data. The results showed that sliced tobacco received an average added value of IDR 2,965 per kilogram, with a ratio of added value to average output value of 83.36 percent during the production process. This value added ratio is included in the high value added category because it is above 40%. This shows that the added value generated from the shredded water leaf tobacco farming business into water leaf shoots is very high. The shredded tobacco business produces 96% profit, with labor income of 3.53%.
Examining the Footprints of the Agreement Establishing the African Continental Free Trade Area in Conformity with the Principle of Legality
Authors: Negusse Berhe Henos
Published: January 2025

Law defines how freedoms are ensured, power allocated and rights granted. Nonetheless, in as much as freedoms, power allocation and rights are expressed in the form of law, they ought to conform to the conditions of the rule of law. One of these is the principle of legality, a consideration as to what law must be like to be called ‘law.’ The principle of legality is a concept which assesses clarity, prospectivity, intelligibility and most importantly, congruence between the former laws promulgated and the proposed ‘law.’ This paper assesses the African Continental Free Trade Area’s (AfCFTA) agreement, alongside its protocols on trade in goods and dispute settlement, with respect to the principle of legality. Specifically, the author examines four areas of the AfCFTA to analyse their level of compliance with this principle. These four areas of the AfCFTA, which are scrutinised under the principle of legality, are: 1) The level of congruence and prospectivity between the AfCFTA and former instruments (the Abuja Treaty, African regional economic communities (RECs) and multilateral agreements); 2) the prospectivity and clarity of the AfCFTA’s principle of flexibility; 3) clarity of the AfCFTA’s non-tariff barrier (NTB); and the prospectivity of the AfCFTA’s dispute settlement. In so doing, the author finds potential problems of redundancy, loosened connectivity, divergences, lack of clarity, impracticality and inefficiency within these four areas of the AfCFTA. Moreover, the author proposes solutions to bridge the gap.
A Critique of Mohamed Adhikari’s The Anatomy of a South African Genocide
Authors: Lento Mzukisi
Published: January 2025

This paper critiques Adhikari’s representations of the crimes of genocide committed on the Hottentots peoples of South Africa by the Dutch settlers in South Africa and the British rule of South Africa in his, The Anatomy of a South African Genocide (2010). The San people went through traumatic experiences as they lost their land and culture since the colonial encounter in 1652. Scholars have asked why Mandela’s black government which came into power in 1994 ignored the San people. Secondly, what can be the implications of this type of non-recognition on the San people? This study focuses on Mohamed Adhikari’s historical narrative entitled The Anatomy of a South African Genocide (2010). Historical narrative is best suited in representing the crime of genocide because this narrative uses verifiable facts and imaginative renderings that amplify the tragedy. The Dutch, the British colonialists, and the African National Congress (ANC) government let the San people down. The San have been pleading with the democratic government to recognise their language, their existence, and their culture. It is a shame to learn that so many years after the attainment of democracy, the San language is not one of the official languages. This study is desktop. The preferred method is qualitative in nature and draws a researcher’s attention to putative texts that can be interpreted to reveal the genocidal experiences of the San and the consequences of being rendered perpetual sufferers in the land that can be described as originally theirs.
Research Data Repositories from Latin America: Analysis and Proposal of Library Functions to Implement Open Science
Authors: Palma Juan Miguel , Torres Vargas Georgina Araceli
Published: January 2025

Globally, the open science movement has as its main principle the openness of publicly funded data and research outputs. It is essential that actors in this movement include the development and implementation of legal, technical and technological infrastructure. The premise of this research was that if the purpose of open science is free access to research products, then technological infrastructure is fundamental to crystallise availability, visibility, reproducibility and unrestricted access. The research aimed to identify actions of the open science movement in Latin America and study technological infrastructure for data repositories developed and implemented there. The methodology comprised a bibliographic review and quantitative methods. For the exploratory analysis, the sources for retrieval of information were official Web portals of library entities, the Registry of Research Data Repositories, and the Dataverse Project. The search was based on defined variables, namely actions, data repository, infrastructure, library collaboration, and repositories in the Registry of Research Data Repositories and Dataverse. Findings were studied through a descriptive content analysis based on defined variables. We found that nine Latin American countries carry out open science actions; eight develop research data repositories; eight implement technological infrastructure to develop repositories; seven collaborate with libraries in open science actions; and seven have their repositories recorded in the Registry of Research Data Repositories and Dataverse, resulting in 62 research data repositories in Latin America. We concluded that these libraries are actors and laboratories with methodological and pragmatic elements that contribute to the organisation, reproducibility, transparency, management and open access that support the paradigm shift which the scholarly communication system requires.

Authors: Nnaeme Chibuikem C
Published: January 2025

Over 1.5% of the global gross domestic product (GDP) is spent on social protection in developing and transition countries. The South African government supports an increasing number of its citizens with reliable and predictable monthly social grants to mitigate high levels of poverty and unemployment in resource-poor communities. Although the literature has shown the positive impact of the intervention on nutrition, schooling, women’s empowerment, access to services, and search for employment, the relationship between social grants, agency and poverty reduction in resource-poor communities is yet to receive adequate research attention. Considering the United Nations (UN) Sustainable Development Goal (SDG) 1: No poverty, as well as the expected role of social grants, this study aimed to explore how the receipt of social grants contributes to beneficiaries’ agency towards poverty reduction in the resource-poor community of Doornkop, Soweto, South Africa. A qualitative research methodology was used to understand the impact of social grants and found that receipt thereof created new economic opportunities, empowered individuals, and boosted the overall economic status of the community.

Environmental Prospects for Energy Sector Development in the Irkutsk Region
Authors: Maysyuk E.P.
Published: January 2025

The prospective development of the energy sector in the Irkutsk region depends on top-priority development strands of high-tech industries of the energy sector with advanced processing of raw materials, development of gas supply systems, and ensuring favorable environmental conditions. As it stands now, environmental conditions in the region are considered unfavorable, and energy facilities (most importantly, power generation facilities) affect all components of the environment in a significant way. Further expansion of coal-fired generation will contribute to more emissions of pollutants and greenhouse gases into the atmosphere, as well as the production and accumulation of coal combustion residuals. Environmental issues of the energy sector can be partially addressed by large-scale gasification. Conversion to natural gas combustion at three major thermal power plants alone will reduce pollutant emissions by 1.5 times in the region. However, the commissioning of a modern coal-fired power plant can offset this effect, which eventually sets the region back to the baseline in terms of pollutant emissions and also entails a 2.5-fold increase in greenhouse gas emissions and a 2-fold increase in the production of coal combustion residuals. Gasification can prove instrumental in addressing environmental challenges faced by the energy sector locally, i.e., in the southern districts of the region. The expansion of coal-fired power generation will preclude complying with the requirements of the Clean Air Project, which is currently being implemented in the Irkutsk region.

Authors: Muzychuk R.I. , Sokolov A.D.
Published: January 2025

The great uncertainty in the values of technical and economic indicators of energy sector development hinders the compilation of projected (calculated) regional energy balances. To address this issue, we propose using the indicator-based analysis aided by simulations to develop projected regional energy balances. This study contributes a simulation model for compiling projected balances, which is meant to facilitate projections of energy sectors of the regions of Russia. The model determines the necessary volumes of extraction, production, and imports of energy resources to ensure that the projected levels of consumption and exports of energy resources outside the region are maintained. The presented model was used to construct indicative fuel and energy balances of the Asian regions of Russia for 2050.

Spin-crossover (SCO) molecular-based switches displaying magnetic bistability have shown promise across a range of applications since their discovery, including sensors, memory storage devices, actuators, or displays. Yet, limited processability remains a substantial barrier to their real-world implementation. Efforts to overcome this limitation by integrating SCO materials into polymer matrices have often been constrained by complex, costly, and time-consuming multi-step methods, which tend to produce inhomogeneous particle distributions within the matrix. Herein, we demonstrate how three-dimensional (3D) flow-focusing chemistry provides unprecedented control for the direct fabrication of SCO composite materials, effectively addressing key challenges in processability, scalability, and cost. By using a continuous 3D coaxial flow-focusing microfluidic device, we simultaneously synthesize [Fe(Htrz)2(trz)](BF4) and achieve its homogeneous incorporation into alginate fibers in a seamless continuous manner. The versatility of the microfluidic device allows for precise manipulation of the reaction-diffusion (RD) zone, resulting in SCO composite fibers with tunable physicochemical and magnetic properties. Additionally, we demonstrate the ability to isolate these fibers as freestanding architectures and highlight the potential for printing them with defined shapes. Finally, we show that the 3D control of the RD zone granted by continuous flow microfluidic devices offers precise spatiotemporal control over the distribution of SCO complexes within the fibers, effectively encoding SCO materials into them. SCO-encoded fibers can seamlessly combine adaptability and functionality, offering innovative solutions for application-specific customization.

Published: January 2025

Conjugated polymers are promising candidates for photocatalyst materials owing to the molecular design flexibility in tuning their properties, including visible light responsiveness. The rational introduction of a molecular metal complex acting as a catalyst at a specific location is an effective approach to activate conjugated polymer photocatalysts for the selective conversion of small molecules, such as carbon dioxide. However, the photocatalytic activity of the conjugated polymer/metal complex hybrids has not been satisfactory. In particular, there is still much room for improvement in polymer structure engineering to maximise the activation of a molecular complex catalyst centre by photoexcited electrons. This work demonstrates the strong impact of side chains and ligand structures, which do not significantly affect the optical properties of the polymers, on their photocatalytic performance for CO2 reduction. The relatively rigid aromatic side chains and condensed aromatic ligand moieties enable effective inter-π-chain charge transfer to activate the isolated (i.e. low-concentration) Ru(II) complex catalyst. The manipulation of photoexcited charge transfer by structural modulation resulted in a significantly improved photocatalytic activity (quantum efficiency of 2.2% at 450 nm) compared to the counterpart photocatalysts containing the alkyl side chain and bipyridine ligand moieties.
Polyelectrolyte brush at thermal equilibrium: A density functional theory approach
Authors: Edwards Mike
Published: January 2025

The long standing problem of Polyelectrolyte brushes at thermal equilibrium is approached here by using density functional theory (DFT) framework. The results confirms that by increasing the Bjerrum length of the medium, the counterions get absorbed by the brush monomers the effect that is known as Manning condensation. Additionally, it turns out that by increasing the Bjerrum Length, the monomers get depleted from the surface but the counterions get accumulated around the surface. These two effects could have potential technological applications in biotechnology etc and shows that how Polyelectrolyte brushes respond to the variation of the Bjerrum length as a key parameter in charged systems.

Published: January 2025

This article is dedicated to the study of the psychological characteristics of the emotional sphere of internally displaced persons (IDPs) from the first wave (2014) and the second wave (2022). The consequences of forced internal migration due to the danger of military actions in both 2014 and 2022 for Ukrainians have resulted in significant changes on economic, social, cultural, and psychological levels. Leaving their comfort zones, citizens from "hot spots" found themselves in the "trap" of the unknown, which often led to the emergence of intrapersonal conflicts: a lack of desire and motivation to change their location while simultaneously being physically unable to stay in their homes and familiar environments. A person's living space gradually deteriorated: their moral values and plans were no longer important or achievable, leading to uncertainty and a sense of insecurity about the future, fear for their own lives and the lives of their loved ones, which caused a shift in their emotional state, chronic fear and stress, feelings of anxiety, heightened guilt, and irritability due to the inability to influence the situation, among others. The practical significance of the presented study is determined by the need for a comprehensive analysis of the emotional and mental states of internally displaced persons, their situational feelings of danger, and the determination of levels of anxiety and depression to overcome these issues and return to a normative way of life. The formulated conclusions may be useful in identifying potential at-risk groups among the Ukrainian population, developing psycho-correctional programs, and conducting psychotherapeutic groups.

Every year the use of vibrating and vibro-impact equipment becomes more and more common. This machinery is successfullyused in the construction of solid foundations for a different building. The main element of these vibrating machines is anunbalanced vibrator. We considered the operation of the unbalanced vibrator in the interaction of mechanical and electromagnetic processes and the result was obtained as a mathematical model of dynamic processes during working the vibrator. The developed mathematical model makes it possible to carry out the analysis of the transients during the operation of the unbalancedvibrator, taking into account the inseparable interaction of the electric machine and the mechanical part of the drive

The problems of estimating the stress-strain state of the foundations during the deep foundation pits installation are considered. The results of finite element calculations in the plane formulation of the stability of the pit walls and the retaining structures' operation under dense urban development are presented. It is proved that the proposed method specifies the calculation of determining the impact of the new building on existing buildings and structures, which enables assigning the design of retaining structures from drilled piles on the conditions of normal further operation of existing facilities. It is established that the parameters of the structures retaining the walls of deep foundation pits in the presence of existing buildings, should be assigned based on the actual condition of these buildings and the allowable additional deformations.

The results show that the experimental studies of long-term fatigue (strength) of steel structures of underground sewage structures in a chemically aggressive environment, simultaneously containing chemical ingredients and biologically aggressive bacteria. It is established that long-term fatigue (strength) of steel structures of underground sewage structures is significantly reduced during long-term operation, and especially when exceeding 20 years or more, in chemically aggressive environments of domestic sewage, which often leads to corrosion and mechanical damage. It is shown that in the course of long service life the indicators of long-term fatigue of reinforcing steel rods of reinforced concrete structures are significantly reduced, which causes the formation of cracks in the connection "reinforcement - concrete", which usually leads to the destruction of reinforced concrete pipes and structures as a whole.
