The interplay of governance and economic performance in Africa: evidence from Granger causality tests
Authors: Bouhlel Sofian
Published: January 2025

This study examines the causal relationships between governance indicators and economic performance across three African regions, Eastern and Southern Africa, Western and Central Africa, and North Africa, using Granger causality tests. The analysis highlights the significant roles of political stability, institutional quality, and economic activities in shaping regional development. In Eastern and Southern Africa, political stability is found to significantly influence both trade and foreign direct investment (FDI), while FDI also impacts the control of corruption. In Western and Central Africa, trade enhances voice and accountability, and political stability, along with government effectiveness, rule of law, and control of corruption, drives FDI. In North Africa, voice and accountability play a crucial role in influencing trade. These findings underscore the importance of stable political environments and strong institutions in fostering economic growth and attracting foreign investment in Africa. The study provides valuable insights for policymakers aiming to promote sustainable development through improved governance and economic strategies.

Published: January 2025

Objective. We analyzed the most researched topics related to the circular economy. To this end, we used a bibliometric approach, generating thematic maps that group the most used terms in the scientific literature.

Design/Methodology/Approach. The present study focused on hierarchical clustering analysis to identify and understand interrelated themes in circular economy research. Adopting Ward's method, the analysis was performed without predetermining the number of groups. The data set was extracted from the Scopus database. Author keywords and keywords plus were used for the study.

Results/Discussion. A hierarchical clustering analysis applied to the corpus of circular economy terms has revealed five main groups: (1) technological innovation and strategic planning, (2) adaptation and resilience in industrial processes, (3) reuse and advanced manufacturing, (4) safety and automation in the circular economy, and (5) material science and chemical sustainability. The interrelationship between the clusters identified in the analysis reflects an integrated thematic ecosystem within the circular economy, with each cluster complementing the others to address multifaceted challenges. Cluster 1, focused on the “circular economy” and “sustainable development,” is the strategic core connecting all clusters' technological and policy approaches. This cluster establishes direct links with cluster 3, where concepts such as “recycling” and “additive manufacturing” are essential to materialize the reuse strategies proposed. Cluster 2, focused on adaptation and resilience, establishes a critical connection with cluster 4 since automation and safety require adaptive models to manage dynamic processes. In addition, cluster 5, focused on sustainable materials and chemical processes, complements the objectives of cluster 1 by providing innovative solutions to improve recyclability and manage waste such as plastic waste and carbon dioxide.

Conclusions. The synergies between the clusters show that progress toward a circular model depends on integrating multiple dimensions, from policy and technology strategies to advances in materials and industrial processes.

Hadis Kaynaklarındaki Tefsir Bölümlerinin Taberî Tefsiri ile Mukayesesi
Authors: AKBAŞ Mustafa Yasin
Published: January 2025

Tefsir rivayetlerini bir araya getirme faaliyeti müstakil Kitâbu’t-Tefsîrler ile başlayıp hicrî ikinci asrın sonlarından itibaren konularına göre tasnif edilmiş hadis kaynaklarındaki tefsir bölümü oluşturulması ile devam etmiştir. Hadis kitaplarındaki tefsir bölümlerinin ilk örnekleri olan Abdullah b. Vehb ve Saîd b. Mansûr’un eserleri tâbiûn dönemi tefsir anlayışını yansıtan bir içerik sunarken Buhârî ile birlikte daha çok merfû ve muttasıl rivayetlerden oluşan tefsir bölümleri oluşturulmuştur. Hicrî ilk üç asır hadis kitaplarındaki tefsir bölümleri hadis-tefsir ilimlerinin teşekkül devrine ilişkin bilgilerin yanı sıra muhaddislerin tefsir bölümleri oluşturmaktaki gayesi, tefsir rivayetlerine bakışı ve eserlerinde yer verdikleri rivayetlerin Kur’ân’ı tefsir imkânı hakkında bilgiler sunmaktadır. Bu makalede hadis kaynaklarındaki tefsir bölümleri Taberî’nin eseri ile mukayese edilmektedir. Taberî ilk üç asırdaki bilgileri bir araya getirip kendi yorumlarıyla zenginleştiren önemli bir müfessirdir. Onun eserinde rivayetlerin yanı sıra tarihi bilgiler, Arap dilinin kuralları, İsrâiliyât ve şiirlerden örnekler âyetlerin tefsirinde kullanılmaktadır. Hadis kaynaklarında ise sadece rivayetlerin (özellikle de merfû rivayetlerin) sağladığı kadar bilgi bulunmaktadır. Bu durum hadis kaynaklarında tefsir bilgisinin sınırlı seviyede kalmasına neden olmuştur.

Authors: AKCAN Ali Veysel
Published: January 2025

İnsanlar devam edegelen hayatlarında olumsuz durumlarla karşılaşabilirler. Bu durumlar hem kendilerini hem de sorumluluk aldıkları akitlerini doğrudan ilgilendirebilir. Zira kimi durumlar, kiralama akitleri imzalanırken hesaba katılmayan ve taraflardan birinin zarara uğrayıp etkilenmesine yol açan olumsuz durumlardır. Makale, kiralama akitlerini kiraya veren kişi tarafından feshetmeyi mümkün kılan ve kişinin kontrolü dışındaki mazeretleri Hanefî mezhebi çerçevesinde ele almaktadır. Söz konusu mazeretler, Hanefî mezhebine göre ele alınarak günümüz güncel meseleleri ile bağlantısının kurulması amaçlanmıştır. Hanefîlerde kira akitlerinde akdi feshettirici mazeret, kira akdinin kendisinden kaynaklanmayan zararlar bağlamında kabul edilmiştir. Mazeretler, akitlerin bağlayıcı özelliklerini kaldırarak taraflardan birine kiralama akdini feshetme imkânı sunmaktadır. Kiraya veren kişinin mazeretleri şunlardır: Fazla borç, kiralanan şeyde önceden var olan kusurlar, kişinin kiralandığı işin toplum tarafından kötü görülmesi, kiraya verenin hasta olması, kiraya verilenin hasta olması, kiraya verilenin yetişkinliğe erişmesi, kiraya verilenin hürriyetine kavuşması, telef olmaktan korku, kira müddetinin olağandışı uzaması, kiraya verenin mallarının çalınma korkusu, kiracının dârü'l-harbe iltihak etmesi, kiracının ahlaksız davranışlar sergilemesi. Bu mazeretler, kira akdi kurulduktan sonra ortaya çıkmaktadır. Bu yüzden akit öncesinde bilinenlerin akdi fesihe etkisi yoktur. Akitten sonra dile getirilecek olursa mazeret olarak değerlendirilmezler.

Published: January 2025

Translation is a difficult scientific activity. The difficulty becomes even more complex when the translator does not find a way to overcome the problem. This means that the translator lacks mastery of translation theory. The scarcity of theoretical and practical studies on Arabic-Indonesian translation is a distinct issue in the world of Arabic-Indonesian translation. In turn, this leads to a low quality of translation. This study aims to analyze the practical patterns of translating Arabic into Indonesian, specifically in forms of meaning changes, such as narrowing, expansion, and omission of meaning. This research uses a qualitative research method with a literature review, namely collecting data by mastering concepts from various literatures that are associated with studies relevant to issues concerning practical patterns of Arabic-Indonesian translation. This research emphasizes the importance of a deep understanding of both languages, including linguistic and cultural aspects, in producing accurate and communicative translations. This study contributes to the field of translation studies by offering insights into effective strategies for overcoming the challenges of meaning shifts. These results are expected to serve as a guide for translators and academics in improving the quality of Arabic-Indonesian translation.

Students' difficulties in learning Arabic, especially in reading and writing skills due to limited vocabulary mastery, are the background to this study. This study aims to analyze the difficulties faced by 4th grade students of Bina Insan Batang Kuis Elementary School in introducing themselves using Arabic. The method used in this research is using qualitative approach with descriptive design. This study took research subjects from 30 students and one Arabic language teacher in grade 4 of Bina Insan Batang Kuis Elementary School. The research data were collected through in-depth interviews with the Arabic language teacher, direct observation in teaching and learning activities, and questionnaires distributed to students to identify the types of difficulties experienced by students in grade 4 of Bina Insan Batang Kuis Elementary School. The results of the analysis show that students experience difficulties in mastering Arabic vocabulary, Arabic sentence structure, and low self-confidence when speaking Arabic. These difficulties are caused by the influence of the mother tongue and the daily or local language used by the students which has a much different language structure, sentence structure and vocabulary and letters used. This study also emphasizes the importance of more interactive teaching methods and additional support in Arabic language learning to improve students' ability to use Arabic. The findings of this study are expected to serve as a basis for teachers and curriculum developers in designing more effective learning strategies.

Authors: Jaskulski Karol , Bobowik Patrycja , Wysoczański Bartosz , Starczewski Michal
Published: January 2025

Purpose: The purpose of this study was to evaluate the effectiveness of a personalized training program to improve lower limb muscle strength and balance in professional female rugby 7 players. Given the strong association between postural stability, muscle strength and injury risk among athletes, and given the high incidence of injuries in rugby, preventive measures are warranted.
Methods: The study group consisted of 15 rugby 7s players (aged: 25.53 ± 4.58 years) who trained at least 3 times per week and had a minimum of 2 years of training experience. They underwent an 8-week training program (2 times per week) based
on the Fifa-11 and Activate protocols. Anthropometric measurements, postural stability assessment using a stabilographic platform, and maximal muscle torque were measured in the participants.
Results: After completing the program, the players achieved significantly better values in static stabilographic indicators with closed eyes: overall stability index (OSI) (P< .05), anterior-posterior stability index (APSI) (P< .01), and medial-lateral stability index (MLSI) (P< .01). Additionally, dynamic indices at various levels of platform instability showed improvement: fall risk index (FRI12-6) (P< .01) and FRI6-2 (P< .001). An increase in the strength of the thigh extensors (right- R: P= .001; left- L: P< .01) and flexors (R: P< .05; L: P< .05) was also observed.
Conclusions: The standard training for rugby players should be supplemented with exercises from the proposed intervention to improve muscle strength and postural stability and thereby enhance proprioception.

Authors: Pereira do Nascimento Paulo Vitor , Domingos da Paz Cristiane , Pereira Josineide Edinalva , Peixoto Ana Rosa , De Jesus Santos Adailson Feitoza
Published: January 2025

Macrophomina phaseolina (Tassi) Goid is a pathogen that causes damping off, stem rot and root rot disease in a broad host range. The method of biological control using bacteria of the genus Bacillus stands out as viable and effective in combating plant diseases. The aim of the present study was detecting the presence of enzymatic compounds produced by the Bacillus isolates and evaluating the in vitro antagonistic activity of the bacterial isolates against M. phaseolina, using the methods of paired culture, pathogen culture on antagonist culture, thermostable and volatile metabolites. The experiments were carried out at the Phytopathology Laboratory, Department of Technology and Social Science, Campus III – UNEB, in Juazeiro-BA. Of the nine Bacillus isolates provided by the LBM, all were molecularly identified, except for isolate B7. The fungus M. phaseolina was acquired from the Dept. of Micologia at Federal University of Pernambuco. The experiment was in a completely randomized design for the enzymatic test using three replicates, and for the antagonism studies a 4x5 factorial arrangement was used (four isolates and four methods of antagonistic activity and the control treatment) with five replicates. Data were subjected to analysis of variance and Scott-Knott test at 5% probability. The enzymes showed the rates: proteases (100 %), cellulases (88%), pectinases (77 %), and amylases (66 %), suggesting that the isolates could be promising in the biological control of pathogens. In the selection of isolates with greater antagonistic activity, the method of culturing the pathogen on the culture, proved to be the most efficient in inhibiting the growth of M. phaseolina.
Composition, developmental patterns, and pathological associations of the human gut mycobiome
Authors: Lee Eun Ha , Hong Chi Rac
Published: January 2025

Purpose: The human gut mycobiome comprises diverse fungal species and plays a crucial role in health and disease, despite its relatively low abundance compared to bacterial populations. This review provides an overview of the mycobiome’s composition, developmental patterns, and dysbiosis in various pathological conditions. As well, the complex interactions of fungal communities within the gut microbiome are discussed.

Current content: The development of the gut mycobiome follows patterns similar to those of the bacterial microbiome, with birth mode, diet, and age being key determinants. In contrast to the bacterial trends, mycobiome diversity increases during childhood and old age. Recent studies have revealed variations in the mycobiome composition across different ethnic groups. Mycobiome dysbiosis is associated with autoimmune, gastrointestinal, and cardiovascular diseases. Certain fungi, notably Candida albicans, are relatively more abundant in pathological states. Fungal metabolic activity, particularly secondary metabolite production, can significantly affect disease progression. Bacterial–fungal interactions in the gut microbiome are complex and modulated by environmental factors, such as diet and antibiotic use. Moreover, the gut mycobiome modulates therapeutic efficacy. Gut fungi enhance the bioactivity of compounds derived from natural products through biotransformation, including their anticancer and anti-inflammatory effects. This suggests the potential of the gut mycobiome to optimize the therapeutic efficacy of natural products.

Conclusion: This review highlights the relevance of the gut mycobiome as both a diagnostic biomarker and a therapeutic target. Future research should focus on elucidating the causal relationships between mycobiome alterations and disease states, and further explore bacterial–fungal interactions within the gut ecosystem.

Introduction. Previous research on the intergel system of polyacrylicacid (PAA) and polyethyleneimine (PEI) revealed that at a hydrogel ratio of 3:3, significant activation occurs at 24 hours. This indicates substantial changes in electrochemical and conformational properties at this ratio. The
purpose of this research is to investigate the remote interaction between the weak polyelectrolyte
polyacrylic acid (PAA) and the weak polybase poly-2-methyl-5-vinylpyridine (P2M5VP) over time and at
various molar ratios in an aqueous environment. The study seeks to explore the activation potential of these hydrogels by analyzing their electrochemical properties using conductometry and pH-metry, and to determine the effect of molar ratios on the specific conductivity and swelling degree of the hydrogels. The obtained results.The maximum conductivity of 14.4 µS/cm was achieved at a ratio of 2:4 at 2.5 hours, coinciding with the minimum pH value of 4.4. In the 6:0 ratio, where only the PAA hydrogel is present, the conductivity changes remained minimal within the range of 1-2 µS/cm, indicating the stability of this hydrogel in the absence of P2M5VP. The swelling coefficient also exhibited interesting dynamic changes depending on the time and component ratios. The swelling coefficient of PAA remained stable at 11-14 for the individual hydrogel but showed a maximum value of 41 at a ratio of 1:5 after 24 hours, indicating significant interaction between the hydrogels. The maximum swelling coefficient of P2M5VP, 7.5 and 7.6, was observed at ratios of 5:1 and 2:4, respectively, 2.5 hours into the study, suggesting optimal interaction of the hydrogels during these time intervals. Conclusion. The studies showed that initial differences in conductivity are minimal; however, significant changes occur over time due to intermolecular interactions between the components. The obtained results can be useful for optimizing the sorption properties of hydrogels in metal extraction processes.

Introduction. Development of effective, cheap and environmentally friendly methods for increasing oil recovery of reservoirs is one of the relevant problems of the oil industry all over the world due to the decrease in the extraction of oil due to the decline in reservoir energy. In this regard, various methods of increasing oil recovery in the fields are applied, including gas flooding. Enhanced oil recovery (EOR) techniques play a crucial role in maximizing oil production from reservoirs. The purpose of this work to investigate the integration of nanoparticles which has gained significant attention due to their potential to address challenges associated with traditional EOR methods. Discussion. The paper focuses on the fundamentals and application of surfactants and nanoparticle mixtures for enhancing oil recovery through CO2 flooding. One of the key challenges when using CO2 to increase oil production is controlling gas mobility. Conclusion. In this paper, the potential of using surfactants and a mixture of surfactants with nanoparticles to create a stable foam that reduces gas mobility and increases oil production is investigated.

Abstract. Modeling the dispersion of volcanic particles following explosive eruptions is critical for aviation safety. To constrain the dispersion of volcanic plumes and assess hazards, calculations rely on accurate characterization of the eruptions source term e.g., variation of emission rate and column height with time and the prevailing wind fields. This study introduces an inverse modeling framework that integrates a Lagrangian dispersion model with lidar observations to estimate emission rates of volcanic particles released during an Etna eruption. The methodology consists of using the FLEXPART model to generate source-receptor relationships between the volcano and a lidar system that observed the ensuing volcanic plume, which then are used to derive the emission rates using the observational data. We leverage data from the ACTRIS PollyXT lidar that operates at the PANhellenic GEophysical observatory of Antikythera. The inversion algorithm utilizes lidar observations and an empirical a-priori emission profile to estimate the volcanic particle source strength, accounting for altitude and time evolution of the plume. Additionally, to study the impact wind fields have on volcanic ash forecasting, the experiment is repeated using fields that assimilate Aeolus wind lidar data. Our approach applied to the 12 March 2021 Etna eruption, accurately captures a dense aerosol layer between 8 and 12.5 km. Results show a minimal difference of the order of 2 % between the observed and the simulated ash concentrations. The presented inversion algorithm coupled with Aeolus data, optimizes both the vertical emission distribution and Etna emission rates, advancing our understanding and preparedness for volcanic events.

Published: January 2025

Abstract. In this study, we assess the relevance and utility of several performance indicators developed within the FAIRMODE framework by evaluating eight CAMS models and their ensemble in calculating concentrations of key air pollutants, specifically NO2, PM2.5, PM10, and O3. The models' outputs were compared with observations that were not assimilated into the models. For NO2, the results highlight difficulties in accurately modelling concentrations at traffic stations, with improved performance when these stations are excluded. While all models meet the established criteria for PM2.5, indicators such as bias and Winter-Summer gradients reveal underlying issues in air quality modelling, questioning the stringency of the current criteria for PM2.5. For PM10, the combination of MQI, bias, and spatial-temporal gradient indicators prove most effective in identifying model weaknesses, suggesting possible areas of improvement. O3 evaluation shows that temporal correlation and seasonal gradients are useful in assessing model performance. Overall, the indicators provide valuable insights into model limitations, yet there is a need to reconsider the strictness of some indicators for certain pollutants.

Published: January 2025

Abstract. Data drives our understanding of hydrological processes, supports model development, and enables anticipatory water management. This contribution introduces EARLS: European Aggregated Reconstructions for Large-sample Studies. EARLS offers daily streamflow reconstructions for more than 10,000 basins in Europe including uncertainty estimates, covering the period from 1953 to 2023. The reconstruction is derived from a single Long Short-Term Memory (LSTM) based rainfall–runoff model trained on more than 5,000 basins. LSTMs represent the state of the art in rainfall–runoff modeling and are well suited to provide predictions in ungauged basins. We evaluate the quality of the reconstruction through quantitative evaluation on two held-out sets of basins and by conducting a qualitative assessment that compares EARLS-based peak flows and flood timing to previous large-scale hydrological studies. EARLS represents a new generation of datasets that harness the capabilities of Deep Learning to obtain accurate and high-resolution data. EARLS is available at https://doi.org/10.5281/zenodo.13864843 (Klotz et al., 2024b)
The Development and Application of an Arctic Sea Ice Emulator v.1
Authors: Chilcott Sian Megan , Meinshausen Malte
Published: January 2025

Abstract. The high computational expense of complex climate models and their tendency to underestimate observational records of Arctic sea ice sensitivity to anthropogenic forcers, challenge our ability to assess the magnitude of forcing that will cause Arctic sea ice loss to cross critical thresholds. To address these limitations, we development an Arctic sea ice emulator, that is calibrated to the response of sea ice area to global warming in physically-based CMIP6 models and constrained to observations. Our constrained emulator reduces the remaining budget of CO2 that can be emitted to prevent seasonally ice-free conditions from 821 GtCO2 by CMIP6 multi-model ensemble estimates to 380 GtCO2. This suggests that limiting global warming to 1.5 °C is sufficient to prevent a seasonally ice-free Arctic Ocean, whereas 2 °C proves insufficient. Our results also provide insight into the future of winter sea ice over a greater ensemble range than previously possible, pinpointing the emission threshold at which the ice pack detaches from land, after which the ice pack rapidly disappears to year-round ice free conditions.

Child marriage often involves adolescents aged 10–19 years and poses significant health risks and challenges to gender equality. The aim of this systematic review was to examine the involvement of adolescent girls in decision-making processes regarding child marriage and identify influencing factors. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this review covered studies published between January 2014 and July 2024. The databases searched included ScienceDirect, Springer Link, PubMed, and Taylor & Francis, using terms related to adolescent girls, decision-making, and child marriage. Inclusion criteria targeted studies involving girls aged 10–19, with methods including qualitative, quantitative, longitudinal, and mixed-method, published in English. Data extraction and quality assessment followed the standards of the Joanna Briggs Institute. Of 6,967 articles, 29 met the inclusion criteria, spanning 26 countries across three continents, with 51.7% being qualitative studies. Economic pressure was identified as the primary driver of child marriage, with significant parental and community influences restricting the girls' decision-making autonomy. Parents, especially fathers, often force girls into marriage to reduce economic burdens and enhance family honor. Some adolescent girls initiate marriage to escape adverse home conditions or societal stigma. Education and strong family support emerged as protective factors, while entrenched social norms perpetuated early marriages. Comprehensive approaches including educational improvement, economic support, and social norm transformation are essential. Addressing child marriage requires multidimensional strategies, encompassing enhanced educational opportunities, economic support, and changing entrenched social norms. Future research should focus on interventions that boost adolescent girls' life skills and decision-making autonomy to delay marriage and enable informed choices.

Burnout syndrome (BOS) is an occupational phenomenon highly prevalent among healthcare workers, particularly physicians and nurses. Despite its prevalence, no single therapy universally addresses all cases of BOS. The aim of this study was to develop a novel approach to managing BOS through traditional music therapy, evaluated from psychosomatic, neurological, immunological, and endocrine perspectives. The study involved 80 participants who were randomly assigned to either the intervention or control group. The intervention group received traditional music therapy for 10–15 minutes, three times a week, over four weeks. Key outcomes were assessed at weeks 2 and 4. Measurements included the Maslach Burnout Inventory (MBI), heart rate variability (HRV), saliva cortisol, saliva β-endorphin, saliva immunoglobulin A (IgA), and serum FOXP3. Instruments included the MBI-HSS questionnaire and HRV measuring devices. Over four weeks, significant improvements were observed in the MBI scores (p=0.001), HRV (p=0.001), and FOXP3 delta (p=0.035) in the intervention group compared to the control group. However, no significant differences were found for cortisol, β-endorphin, or IgA. These findings suggest that traditional music therapy positively impacts the psychological, neurological, and immunological aspects of BOS and potentially influences immunological and endocrine responses. Future research should explore the effects of longer intervention durations, test varying doses, and examine the combination of music therapy with other non-pharmacological treatments to enhance its therapeutic potential.
