A fabric from the Hallstatt period yet unseen in Central Poland – some remarks on the find from Dąbrowa, Wieluń County
Authors: Janiak Radosław , Słomska-Bolonek Joanna
Published: September 2024

During excavations carried out in 2023 at the cemetery of the Lusatian culture in Dąbrowa, site 2, Wieluń County, an urnless cremation burial was discovered (Object 24), which is dated generally to the Hallstatt period. Burnt human bones were scattered throughout the object, which form a relatively compact cluster in the central part of the grave. Ceramic fragments from various vessels were found in the fill of the grave cavity. Metal objects, both bronze and iron, showed signs of being smoldered in the fire. This fosters the conclusion that they had been burned with the deceased on the pyre and placed in the grave together with burned human bones. At the same time, such a state of preservation of the grave offerings made it impossible to specify the dating of the tomb. Within the grave, a fragment of an iron plate was found, on which mineralized remains of fabric were preserved. Technological analysis showed that it was a half-basket weave fabric of a very high quality, made of thin z-single yarn (0.25–0.30 mm and 0.40–0.50 mm) and of surprisingly high thread count (32–34/12–14 threads per cm). In the basin of the Vistula and the Oder rivers, none of the fabrics discovered so far had similar parameters. On the other hand, textiles from the main canters of weaving production at the time, such as the Hallstatt culture and the Scandinavian area, showed similar characteristics, but only in rare examples. This highlights the importance of the weaving product presented here. It is difficult to answer conclusively whether we are dealing in this case with an imported object or one produced in a local weaving workshop, although much points to the first option. Given the context of the find and the accompanying offerings, it can be assumed that the fabric belonged to a person of a higher social status. The local community’s custom of accumulating and then depositing imported items of quality into graves also makes such a hypothesis plausible. On the other hand, certain foreign patterns were adopted and creatively developed in local craft workshops of the Lusatian Culture. Most likely, involvement in long-distance trade routes allowed this society to achieve a high position in the aforementioned exchange. It was important to settle and control areas located in the basin of the upper Warta and Prosna rivers, i. e., on the southern borderlands of central Poland. It was here, through Silesia, that foreign patterns flowed in, which were then transmitted further along the Warta river basin in the northern direction, towards the “Lusatian interior”. The communication route created for the Baltic amber trade played an important role here. Finds of this raw material were recorded both in the Hallstatt circle, in areas of northern Italy, and present-day Slovenia.

A Primer on Human Birth Theory
Authors: Polese Daniela , Fagioli Francesca
Published: September 2024

In the 1970s Massimo Fagioli (1931-2017) proposed a new theory of mind that he called the Human Birth Theory, based on a healthy conception of the baby and of the nonconscious mind. Fagioli made significant contributions to the understanding of mental dynamics at birth, the pathophysiology of mental illness, and the nonconscious identity of psychiatrists and psychotherapists. His original contributions to psychodynamic psychotherapy included variations on the setting and understanding of transference and dream interpretations that deviated from classical psychoanalytic techniques. This article introduces the basic tenets of Human Birth Theory, its neuropsychiatric correlates, and clinical applications.
Whole nervous system expression of glutamate receptors reveals distinct receptor roles in sensorimotor circuits

Published: September 2024

A goal of connectomics is to reveal the links between neural circuits and behavior. Larvae of the primitive chordateCionaare well-suited to make contributions in this area. In addition to having a described connectome,Cionalarvae have a range of readily-quantified behaviors. Moreover, the small number of neurons in the larval CNS (∼180) holds the promise of a comprehensive characterization of individual neurons. We present single-neuron predictions for glutamate receptor (GlutR) expression based onin situhybridization. Included are both ionotropic receptors (AMPA, NMDA, and Kainate), and metabotropic receptors. The predicted glutamate receptor expression dataset is discussed in the context of known circuits driving behaviors such as phototaxis, mechanosensation, and looming shadow response. The predicted expression of AMPA and NMDA receptors may help to resolve issues regarding the co-production of GABA and glutamate by a subset of photoreceptors. The targets of these photoreceptors in the midbrain appear to express NMDA receptors, but not AMPA receptors. This is in agreement with previous results indicating that GABA is the primary neurotransmitter from the photoreceptors evoking a swimming response through a disinhibition mechanism, and that glutamate may, therefore, have only a modulatory action in this circuit. Other findings reported here are more unexpected. For example, many of the targets of glutamatergic epidermal sensory neurons (ESNs) do not express any of the ionotropic receptors, yet the ESNs themselves express metabotropic receptors. Thus, we speculate that their production of glutamate may be for communication with neighboring ESNs, rather than to their interneuron targets.

Significance StatementSimple invertebrates offer a tractable alternative to complex vertebrate brains, facilitating holistic understanding of brain function. One such invertebrate is the marine chordateCiona, which has the benefit of a complete synaptic wiring diagram for its swimming larva. This “connectome” allowed identification of putative neural circuits driving defined behaviors. Fuller understanding of neural circuits, however, requires a description of the attributes of individual neurons. This study focuses on the excitatory neurotransmitter glutamate, which signals via a complex set of both ionotropic and metabotropic receptors. Here, we present a nervous system-wide prediction of GlutR expression inCionaat the individual neuron level, considered in the context of neural circuits, with emphasis on how GlutR expression accounts for function of neural circuits.
THE EFFECT OF A MULTIDISCIPLINARY PSYCHOSOCIAL SUPPORT PROGRAMME ON THE RESILIENCE OF FEMALE ADOLESCENT RECIPIENTS IN JOHANNESBURG
Authors: Hill Robyn Anne , Calitz Taetske Monique
Published: September 2024

The Ruth First Jeppe Memorial Trust (RFJM Trust) provides scholarships to deserving female secondary school learners in Johannesburg and offers a pilot multidisciplinary psychosocial support programme (MPSP) developed by a social worker to enhance their resilience and to facilitate the achievement of their potential. South African female adolescents are challenged daily by their social, economic, cultural, political and historical environments, which in combination threaten their development and functioning. Therefore, female adolescents require high levels of resilience to thrive. Through the pre-test/post-test measurement of the individual, relational and contextual protective resources of Grade 8 recipients of the RFJM Trust, a paired-samples t–test and correlation analysis determined that two aspects of the MPSP have moderate to large correlations with resilience. This quantitative, quasi-experimental, evaluative study will assist in improving the MPSP and contribute towards evidence-based practice in school social work. Keywords: evidence-based practice, female adolescents, resilience

Published: September 2024

Realisation of women’s full participation in all spheres of society remains inconsistent and progress towards gender equality is slow. The COVID-19 pandemic laid bare existing and deeply entrenched gender inequalities. In this article, we draw on multiple HSRC-led studies conducted between 2020 and 2022 that explored the impact of the COVID-19 pandemic and lockdown on the psychosocial and economic wellbeing of women and their families. We show that many women at the community and household level took up the majority share of unpaid household and childcare duties, and faced persistent socio-economic threats, gender-based violence and increased mental health concerns compared to their male counterparts – all of which impeded their ability to lead productive and fulfilling lives. Insights are offered for intersectional gender-responsive policy responses that favour women as central role players in families and the economy.

Introduction. The article is devoted to the problem of using a value-semantic approach in the process of preparing future teachers for the implementation of the main directions of the Federal Work program of education. The purpose of the study is to analyze the degree of understanding by future primary school teachers of the essence of education as a process of value-semantic interaction with children, to identify their knowledge about the methods and forms of such interaction and to determine the necessary adjustments to the content of pedagogical education. Methodology. To achieve the purpose of the study, the following methods were chosen: ranking, questioning, the method of unfinished sentences, which allowed us to assess the readiness of students of the Faculty of primary school teacher training to implement the main directions of the Federal Work program of education. Results. The personal value orientations of future teachers are family and family traditions, care and help, life and the meaning of life; the value orientations for students are care and help, patriotism, family values. Future teachers see the essence of the education process in creating conditions for personal development, and not in organizing value-semantic interaction with students. Most future teachers are aware of the goals and objectives of the Federal Educational Work Program, but do not know how to organize the educational process at school. Conclusions. The article concludes that it is necessary to prepare future teachers for the implementation of the main directions of the Federal Work program of education based on a value-semantic approach and provides recommendations for its implementation in the educational practice of the university.

Introduction. The article is devoted to the substantiation of the theoretical and methodological foundations of the process of formation of creative self-expression skills in preschool children in the process of artistic and aesthetic activity, which allow to identify patterns and principles, as well as prospects for the development of the studied direction in the pedagogy of preschool childhood. Methodology. The article provides an analysis of the content of key methodological provisions based on the analysis of scientific sources on the problem of research, as well as general scientific methods of analysis, generalization and synthesis. Results. The article analyzes the “mechanisms” of the formation of creative self-expression skills in children of preschool and primary school age in the process of artistic and aesthetic activity; a detailed justification of the three selected approaches (systemic, culturological, subject-activity) and principles (cultural conformity, dialogic, integrative artistic and aesthetic development of reality, emotional openness, value-semantic orientation of artistic and aesthetic activity, empathic interaction, polysubjectivity), which form the methodological basis of the study, is presented. Conclusions. For the first time, the paper reveals the initial methodological foundations of the process of formation of creative self-expression skills in preschool children in the process of artistic and aesthetic activity, making a significant contribution to the expansion of scientific ideas about the creative self-disclosure of a child by means of artistic and creative activity. The expediency of using systemic, culturological, subject-activity approaches as a methodological basis for the formation of creative self-expression skills in older preschool children in the process of artistic and aesthetic activity is substantiated. It is shown how the general ideas of these approaches are implemented through the holistic implementation of a number of provisions and principles.

Authors: Elizondo Borbón Mariam Emilce
Published: September 2024

This text deals with regional integration in Central America. Its main objective is to evaluate the different approaches present on this subject in the Anuario de Estudios Centroamericanos (AECA). For this, the bibliography collected and studied during the Scientific Initiation project entitled: “Los proyectos de integración en las revistas de relaciones internacionales del continente americano (siglos XX y XXI)” was used; the investigation title is: “El Pensamiento Integracionista en el Anuario de Estudios Centroamericanos”. Firstly, a section was created with articles related to the subject until 2022, which resulted in a total of 43. Secondly, these texts were summarized and used as sources to group the information in order to carry out a historical follow-up of Central American integration. The research shows that there are insufficient articles on the subject in the AECA. Therefore, this situation must be analyzed from the point of view of scarcity, resulting in aspects such as: integration and peace, hegemonic integration, disintegrations, and migration. It is concluded that the weight of economic interests linked to the United States, the hegemonic power in the region, have reduced the relevance of the political and social aspects of cooperation that would benefit more people.

Published: September 2024

This article is a description of the life path of the Holy Martyr Anatoly Ivanovsky (1863-1918), presbyter of Mari. It attempts to show this new martyr of the Russian Church as a musician, singer and church composer. Therefore, the article pays special attention to the facts of the biography of Priest Anatoly, related to this particular creative side of his life.The article covers the period of his life, and this is the end of the XIX – beginning of the XX century. Historical events, the mood of the society of that time – all this was reflected in the destinies of people, in the fate of a rural priest, a man musically gifted by nature. Having grown up in a pious family of a priest, who loved church singing from childhood and had a wonderful voice, he did not abandon clerical obedience throughout his childhood and youth, right up to his marriage and ordination. Further, Father Anatoly set an example of a zealous and caring pastor, a hard worker, a talented teacher and leader, the father of a large family of gifted children like him, as well as a musician, a connoisseur and connoisseur of church singing.The beginning of the XX century is a time of deep upheavals of the entire Russian society. The terrible persecutions inflicted on the Russian Orthodox Church revealed to the world the true ascetics of piety. In the atmosphere of betrayal and denunciation that engulfed people, they had to make a difficult choice: stay with Christ, faithful to death to Him, or break down under the pressure of the Bolsheviks. The steadfastness shown by priest Anatoly in the most difficult events of his fate showed the world the holiness of this simple village priest, who currently, standing before the Throne of God, is the intercessor and prayer book of all those who turn to him for help.
Moscow in the life of Ivan Alexandrovich and Mikhail Andreevich Ilyin
Authors: Kyzlasova Irina , Ulanova Anzhela
Published: September 2024

The article is devoted to the inextricable connection with Moscow of several generations of the Ilyin dynasty. Moscow has become a symbol of the motherland for two prominent Russian scientists – representatives of an ancient noble family. The outstanding philosopher and patriot-exile Ivan Alexandrovich Ilyin always remembered his Alma Mater and bequeathed his personal archive to Moscow University, where it was returned in 2006. Among more than 70 thousand sheets of manuscripts, scientific papers, letters, photographs, there was an academic badge of a university graduate, which the scientist treasured very much. The image of his native Moscow is also captured in the ex-libris of I.A. Ilyin, found on books from his library. Mikhail Andreevich Ilyin, a prominent art historian, was formed on the deep foundation of the noble culture of his ancestors during the Soviet period, whose research and educational activities took place within the walls of Moscow State University. Among the works of the scientist, a particularly important place belongs to the vast topic of Moscow architecture and closely related Moscow region architecture. He introduced many valuable monuments and sources into science, and for the first time comprehended many of them. Mikhail Andreevich found eternal rest in the columbarium of the Vagankovsky Cemetery in Moscow, where the Ilyins' family burial has been preserved. In 2005, he returned to his homeland and now rests in the necropolis of the Donskoy Monastery the ashes of Ivan Alexandrovich Ilyin.

Considered are possible directions for improving the means of ensuring the quality of electric power (PQ) in order to increase their efficiency, taking into account the schematic and mode features of integrated ship electric power systems (SEPS) with semiconductor propulsion complexes (SPC). One- and two-link variants of system controlled filter com-pensation devices (CFCD) designed for simultaneous full compensation of reactive power, as well as significant weak-ening of harmonic distortions of voltage and current in SEPS with SPC, are proposed and investigated. A modeling approach has been implemented that allows to compare the effect of the proposed CFCD on the integral coefficient of voltage harmonic distortions in systems with different types of input rectifiers as part of the frequency converters (FC) of the SPC, taking into account the possible deviation of the frequency of the ship's network.

The iterative two-channel feed electric drive (ED) with the summation of movements on the rotating sliding nut (RSN) is designed to increase the speed and accuracy of traditional single-channel ED feed mechanisms (FM) of metal-cutting machines with an inertial working tool (WT). A refined generalized mathematical model of movement of the two-channel ED with RSN was obtained, which was built for WT FM of the high-precision coordinate metal-cutting ma-chine of the 24К60АФ4 model. The model takes into account the main static moments of resistance during metalwork-ing, as well as the nonlinear nature of the sliding friction forces in the machine WT FM. Convenient recurrence rela-tions are obtained for the calculation and modeling of sections of the linearized friction characteristic. The structural-algorithmic diagram of the compensated iterative two-channel feed ED with subordinate configuration of control chan-nels is proposed, which makes it possible to compensate in steady-state conditions the negative impact on the accuracy of WT feed of the main static moments of resistance and nonlinearities of sliding friction forces in the drive load.

The paper presents the results of studing the problem of monitoring the condition of an overhead power line wire. The known approaches to the formation of a device for monitoring the sagging boom and ice-coating on the line wires are analysed. It is shown that one of the most promising approaches is based on measuring the angle of inclination of the wire sagging curve near the point of its fixation on the support. It is shown that an unambiguous correlation between the slope angle of the sagging curve and the wire sagging arrow allows for an indirect measurement of the operating temperature of the wire in the absence of ice deposits. It has been shown that equipping the monitoring device with a temperature sensor will allow monitoring the weight of ice-coating and, if necessary, issuing a signal for organising anti-icing measures. Modification of the device with a three-axis gyroscopic sensor allows for additional monitoring of wind pressure on overhead line wires. The paper presents mathematical models for solving these problems of monitor-ing the condition of the wire.

A study of the power balance of the semiconductor voltage regulator on an active load with phase control by two-operation thyristors was carried out. The suitability of its use for simultaneous obtaining of the reactive power resource for distribution electric networks has been confirmed. According to the concept of intelligent electrical networks, such devices belong to the class of flexible alternating current transmission systems, and they can be the basis for building virtual energy sources. The power components for individual components of the regulator, including the thyristor block, were studied. The spectral method of describing currents and voltages at the regulator sections is applied. The obtained results of theoretical studies were confirmed by an example with numerical calculations, which made it possible to clarify the physical essence of energy transformations during voltage regulation.

The current state of the electric power system of Ukraine is considered. The basic principles of restoration and modernization of the generating equipment of the country's power plants in the postwar period are formulated. It is proposed to restore generation at a fundamentally new level with the involvement of advanced achievements of the world and domestic electrical engineering. When restoring destroyed power units, turbine generators with improved performance characteristics should be used selectively, taking into account the nature of the load, the geographical location of the plant, the availability of electrical connections, etc. First of all, we are talking about fully air-cooled machines with enhanced maneuverability (including asynchronized ones). The main advantages of such turbogenerators are named and the elements and components of the structure are identified, the technical condition of which is generally a determining factor in ensuring reliable operation. Examples of technical solutions to improve stator reliability are given. Ref. 14, fig. 6, table.

El presente artículo trata de un estudio de caso sobre la película costarricense Presos (2015) del director cinematográfico Esteban Ramírez. El objetivo principal es realizar un análisis psicosocial, a través de tres líneas teóricas, estas son, el Marxismo impulsado por Karl Marx, el Psicoanálisis de Sigmund Freud y el Feminismo desde la óptica de Norma Blázquez 2017, apoyados secundariamente por otras personas autoras. A lo largo del escrito, se puede encontrar ejemplificaciones de sucesos de la película, en función de aplicar los conceptos teóricos. Para describir a grandes rasgos, se evidencia cómo el sistema capitalista aún sigue vigente actualmente, cómo la inhibición de conductas-pensamientos ocasionan malestar, o, cómo desde el feminismo se propicia una crítica fuerte hacia la desigualdad de género. Finalmente, se concluye que las teorías clásicas, pese a su longevidad, siguen siendo fuente de explicación de nuestra realidad.

Published: September 2024

In recent advancements, the development of smart packaging systems for food has focused on utilizing composite materials to enhance functionality and sustainability. In this study, the composite film from chitosan and PVA was combined at various concentrations (ranging from 0.1% to 0.5%) with the addition of Cu(500mM) and 1% STPP at a 5:1 ratio. An additional indicator was included to detect fish spoilage. The synthesized chitosan material was then blended with PVA to form a composite film. The film was characterized using FTIR, which confirmed the presence of fingerprint vibrations indicating the cross-linking between TPP, chitosan, and Cu. These bonds were observed at wave numbers 1118 cm-1, 879 cm-1, and 603 cm-1. SEM analysis revealed that the film had particle sizes ranging from 865 nm to 1.49 μm. XRD analysis showed distinctive features of pure chitosan and chitosan composite. The composite film K-05 produced an amorphous structure, indicating decreased crystallinity due to the addition of STPP and Cu. The water uptake test demonstrated that an increased concentration of chitosan in the composite led to higher absorption and solubility effects. Conversely, the addition of chitosan in the film decreased water vapor permeability as determined by the water vapor permeability test. The antibacterial test conducted on all films (concentration of 0.1% to 0.5%) indicated that the films K-01 and K-02 exhibited the best zone of inhibition against Escherichia coli. This study sucessfully synthesized and characterized a smart packaging film composed of polyvinyl alcohol (PVA), chitosan, copper (Cu), and bromocresol green (BCG) indicator, designed to monitor food freshness through visual pH changes and inhibition of microbial growth.

Published: September 2024

Centella asiatica known as pegagan in Indonesia, belongs to the Apiaceae family and is widely used as salad, cosmetics ingredients, and herbal medicine for improving memory. This research aimed to determine the total phenolics content (TPC), antioxidant capacity (AC), and FTIR spectrum of C. asiatica leaves extracts using different extraction methods. C. asiatica extracts were prepared using maceration, reflux, and ultrasonication. The Folin-Ciocalteu method was used to determine TPC, and we found a higher level of TPC when using maceration, about 9,96 ± 0,20 mg GAE g-1 dry powder. Antioxidant capacity from the three extracts was measured using DPPH and FRAP methods. The highest antioxidant capacity using DPPH and FRAP methods was found in C. asiatica leaves extract using maceration with a value of 29,60 ± 0,71 and 14,04 ± 0,38 𝜇mol TE g-1 dry powder, respectively. The FTIR spectrum of each extract indicates the presence of vibration from several functional groups such as O-H, C-H, and C=C, likely from phenolics and C-O. The pattern of FTIR spectrum from the three C. asiatica leaves extracts gives different spectrum profiles and characteristics. Principal component analysis using FTIR spectrum data shows good clustering for each extract with 89% data variability (PC1 77% and PC2 12%). It can be concluded that TPC, AC, and FTIR spectrum profiles are different when using different extraction methods.

Black fruit is a native Papuan plant that faces extinction if it is not propagated. The availability of scientific information on the potential use of black fruit can help proliferate this plant. This study investigates the potential of black fruit plants in the leaves and flesh of the fruit using extraction, characterization, and extract activity testing. Extraction was carried out by maceration using a 96% ethanol solvent. Characterization was carried out by FTIR, UV-Vis spectrophotometers, and phytochemical screening. The antioxidant activity test was carried out by the DPPH method, the antibacterial test was carried out by the well diffusion method, and the toxicity test was carried out by the BSLT (Brine Shrimp Lethality Test) method. The results showed that the ethanol extract of black fruit flesh separated into two layers when stored in the refrigerator, while the leaf extract did not. Leaf extract is richer in phytochemical content compared to fruit flesh. Antioxidant and antibacterial activities were higher in leaf extracts than in fruit pulp extracts. Toxicity test results showed that the ethanol extract of black fruit leaves has the potential to be used as a food additive for antioxidant and antibacterial properties. The potential benefits of the ethanol extract of black fruit leaves and flesh can encourage cultivation and post-harvest management of this plant.

Naphthalene derivative compounds named Eleutherol (1) and Eleutherol C (2) have been isolated from Bawang Tiwai Bulb Eleutherine bulbosa. We tested its cytotoxic activity against T47D breast cancer cells in vitro after isolating compounds 1 and 2 from the EtOH extract using conventional chromatography methods. Their chemical structures were elucidated based on spectroscopic analysis, including IR, HR-TOFMS, 1D, and 2D NMR, and by comparison to those related spectra previously reported. Compounds 1 and 2 were tested for their cytotoxic effects against T47D breast cancer cells and showed moderate cytotoxicity against T47D breast cancer cells with IC50 values of 117.15 and 80.21 µM, respectively, compared with cisplatin 24.07 µM.

Published: September 2024

Excessive exposure to ultraviolet (UV) rays can damage facial skin. Carbon Quantum Dots (CQDs) are active ingredients that can be formulated into peel-off masks needed to protect facial skin from UV exposure. This research aims to formulate a peel-off mask as facial skin protection made from the active ingredient CQDs from rice washing water, test the characteristics, and determine user responses to the product. The mask formulation is divided into five versions, namely F0 (without CQDs), F1, F2, and F3 (with CQDs added at concentrations of 2%, 4%, and 6%, respectively), and F+ (with added vitamin C). The resulting formulations were tested through physical tests, fluorescence using a UV lamp, and UV blocking tests. The test results for the five mask formulas showed a pH range of 4.5-5.6, stability over three weeks of storage, drying time within 27-30 minutes, homogeneity, viscosity ranging from 12,810-18,430 cPs, and spreadability ranging from 5.4-6.6 cm. The results of the organoleptic test using the one-way ANOVA test show that variations in mask formulas do not have a significantly effect on preferences for color, smell, texture, and general preferences. The results of the fluorescence test showed that there was luminescence in formulas F1, F2, and F3. UV blocking properties in the wavelength range 290-320 nm are shown in the formulas F1, F2, F3, and F+. Based on these tests, it can be concluded that the peel-off mask formulation with CQDs from rice wash water successfully produced a good peel-off mask product with a high SPF value, especially in formula F3.

The objective of the paper is to characterise the problem of formulating issues and objectives of negotiations as the one of the most important stages of the concept of planning negotiations within a company. The idea and types of such negotiations are first described, followed by the methodological concept of their planning. The three subsequent parts of the paper look at the formulation of issues and objectives of negotiations, namely: their interpretation, the process of formulating them itself and the tools - the principles and methods - applied to solve particular problems within such a process.
European imperialism and colonialism in Africa: conceptual lessons for understanding the former Soviet Union and present day Russia
Authors:   National University of Kyiv-Mohyla Academy (Ukraine), Yakovlyev Maksym
Published: September 2024

This article claims that the legacy of European imperialism and colonialism in Africa can be conceptually compared to the legacy of Russian and Soviet imperialism and colonialism in the former USSR republics and the nations of Central and Easter Europe that were under Soviet dominations. Despite the obvious fact that the historical conditions and paths of African nations that were colonized, repressed and ruled by the European empires differ significantly from the experience of the nations of Eastern Europe and Central Asia, that were conquered and colonized by the Russian Empire and later on were subjects to the Soviet rule, it is suggested in this article, that the conceptual lessons drawn from the vast literature dedicated to the studies of the aftermath of colonialism in Africa can enrich the scholarly efforts aimed at understanding the post-soviet spaces and different processes in it. What is meant by “conceptual lessons” is methodological opportunity for a different perspective or even a different lens through which the legacy of the Soviet rule and the current Russian neo-imperial foreign politics can be better understood. Much is written about the European imperialism and its colonial policies, however there is still some reluctance in applying the methodological framework of postcolonial studies to the former Soviet Union and present day Russia. Scholars all over the world studied the colonial legacies that African nations struggled to overcome and there are topics of particular relevance to the study of the post-soviet space: the processes of post-colonial nation building, the roles of new national elites, the ideological choices in foreign policies of newly independent nations, the aftermath of the policies of assimilation, the imperial “ideologies of superiority”, the economic consequences of colonialism, the role of churches and religious organizations in supporting colonial suppression – as conceptual topics, all of them can be studied critically, also in a comparative perspective, to have a much better understanding of the former soviet and current Russian foreign politics and policies.
Evaluation of the Perceived Support Quality of E-Government Users in Tanzania. Case Study of Government E-payment Gateway
Authors:   University of Commerce and Services in Poznań (Poland), Kemincha Riziki
Published: September 2024

This study was conducted with the general objective of investigating GePG users’ perceived support quality using a case study of the GePG system’s end-users. The study was conducted in Tanzania using a cross-sectional research design which employed a sample size of 102 respondents, who were administered a questionnaire survey to collect primary data, which was later analysed using Principal Components’ analysis, Descriptive Statistics, and Pearson’s Correlation. The findings revealed that end-users of the GePG system positively perceived the quality of the GePG system; based on PCA analysis findings, respondents were neutral with the quality of support from the GePG system support team, as they neither agreed nor disagreed, and the study found a negative weak correlation between satisfaction levels with the quality of support from GePG and end-users’ intention to continue using GePG’s payment services. Therefore, the study concluded that despite end-users’ positive perception of the quality of the GePG system based on ease “of use and responsiveness”, end-users of the GePG system were neutral on rating the quality of the support they were receiving from the GePG support team. Thus, the study recommended that to ensure the sustainability of the GePG system, more resources and efforts need to be directed into the support team of the system to clearly understand the end-users’ challenges.
Factors Influencing Life Expectancy in Low-Income Countries: A Panel Data Analysis
Authors:   University of Piraeus, Gazilas E. T.
Published: September 2024

Understanding the factors influencing life expectancy in low-income countries is crucial for formulating effective health and economic policies. This study aims to explore the determinants of life expectancy in these countries by analyzing panel data from 2004 to 2021. The hypothesis posits that economic indicators, healthcare expenditure, and agricultural land significantly affect life expectancy, while high HIV prevalence negatively impacts it. The research procedure involved using Ordinary Least Squares (OLS) regression analysis with life expectancy at birth as the dependent variable and GDP per capita (PPP, constant 2021 international $), government health expenditure per capita (current international $), agricultural land (% of land area), HIV prevalence (% of population ages 15–49), and current health expenditure per capita (current international $) as independent variables. The main results indicate that GDP per capita, government health expenditure, and agricultural land positively influence life expectancy, highlighting the importance of economic growth, healthcare investment, and food security. In contrast, HIV prevalence has a significant negative effect on life expectancy, underscoring the health burden of the epidemic. Statistical tests for heteroskedasticity and normality reveal some deviations, but the robustness of the analysis is maintained through appropriate econometric techniques. Theoretically, this study contributes to the literature by providing a nuanced understanding of how economic and health-related factors interact to affect life expectancy in low-income countries. Practically, the findings suggest that policies aimed at boosting economic growth, increasing healthcare spending, improving agricultural practices, and addressing HIV/AIDS are vital for enhancing life expectancy. This research offers valuable insights for policymakers in low-income countries striving to improve population health outcomes.
Political interpretation of social processeschanged reality: political-values aspect
Authors: Leskova Irina , Mchedlova Elena
Published: September 2024

The article analyzes transformational political, ideological and sociocultural processes occurring in a constantly changing reality. The basic values of democracy, emerging contradictions and conflicts, relations between the state and the church, etc., which largely determine future social processes, are studied. It talks, in particular, about human rights as a new type of political and legal culture and ideology, which is aimed at «preserving the people» (more precisely, their identity and cultural originality), as well as what violations they are subject to, and how they can be resolved pending difficulties.

Issues of state-confessional relations, which involve a comparative solution to the problem of realizing the interests of society and each of its layers, have become the subject of the political science of religion described in the article, which considers this socio-cultural phenomenon as one of the main environments for political socialization, i.e. formation of political attitudes and values of individuals and groups; and also to create a democratic climate, social work, global diasporas. Religious organizations are considered by this applied subdiscipline as elements of the institutional subsystem of society (along with the party system and the media), especially due to their ability to influence the government and politicians.

Based on recent political science and sociological research, it shows the interrelation and interdependence of social processes with political and, especially, geopolitical realities, rich in various significant political events — a terrorist attack, the Northern Military District, the election of the President of the Russian Federation, his subsequent inauguration on May 7, the Victory Parade and related him the procession of the Immortal Regiment and many others. An interpretation of these events is given from a political science point of view.
