The Role of Technological Innovations in Improving Oil Extraction Efficiency in South Sudan
Authors: Kadugala Aniceto
Published: January 2025

Purpose: The purpose of this study was to explore the role of technological innovations in improving oil extraction efficiency in South Sudan, with a specific focus on recovery rates, operational costs, reservoir management, and real-time data accuracy.
Methodology: In the research, a descriptive methodology was used to find out the effect of the contributing factors on the oil production results.
Findings: Results show that EOR methods, such as reactive injection of water (CW), clearly increase the recovery yield, and reactive injection of gas (GE) technologies obviously enhance the recovery efficiency and the energy security. Further, real-time information systems and modern reservoir management techniques facilitate better decision-making, more efficient production activities and are also scarcity-reducing. Nonetheless, development of South Sudan's oil sector is constrained by the presence of outdated infrastructure, lack of technical ability and insufficient funding for technology.
Unique Contribution to Theory, Practice and Policy: The conclusion reached from the study is that these innovations are necessary to help with maximizing resource use, to help with cost reduction and to enable sustainable development in the country's oil industry. Target areas of advice include giving importance to EOR methods, incorporating real-time data technology, and developing technical capacity to modernise the South Sudan oil industry.

Authors: Ugrak Ugur , Çınar Şafak , Seyhan Fırat , Kavak Demet
Published: January 2025

Purpose: The purpose of this qualitative study is to examine the healthcare supply process in public hospitals in a multi-dimensional manner and to reveal the weaknesses and strengths in this process.
Method: This qualitative study was conducted among stakeholders with sufficient knowledge and experience about healthcare supply processes in public hospitals. Within this research scope, semi-structured interviews were conducted with 14 participants determined using purposeful and snowball sampling methods. The data was analyzed using the thematic coding method with an inductive interpretive phenomenology approach. Nvivo 2020 software was used during the analysis process.
Findings: The current legislation in Türkiye was observed to allow for various supply methods. The open tender method was determined to be the best cost-advantage one in terms of economy of scale. However, it may cause a decrease in material quality. Therefore, well-designed specifications and qualified human resources play an essential role in the supply process.
Originality: This study reveals the possible negative effects of a cost-oriented approach in the supply process on quality in public hospitals. Additionally, the necessity of quality human resources in the supply process of healthcare was identified as an important problem. Informal structures were also emphasized among suppliers, which may disrupt the competitive environment.

Published: January 2025

The retail industry has experienced significant growth with the advent of e-commerce platforms like Jumia. Predicting sales accurately is critical for inventory management, marketing strategies, and overall operational efficiency. This paper explores the application of machine learning techniques to predict sales on Jumia, leveraging historical sales data and other relevant features to build and evaluate predictive models. Our results demonstrate that advanced machine learning models, particularly the gradient boosting machine, significantly outperform the baseline linear regression model. The gradient boosting machine achieved the lowest Mean Absolute Error (MAE) and Mean Squared Error (MSE), highlighting its superior prediction accuracy. Feature importance analysis revealed that pricing, promotional activities, and seasonal factors are key drivers of sales. These findings indicate that machine learning can effectively capture sales patterns, providing valuable insights for decision-makers.

Authors: Novoa Jaso María Fernanda , Breeze Ruth
Published: January 2025

This article examines the coverage of the conflict in Ukraine on the CGTN English website during the first three months. Through a quantitative content analysis of 1,799 news items, this research identifies the predominant frames, social actors, and sources of information employed in the media coverage. The results reveal that the “diplomatic frame” predominates, followed by the “war frame”. The “economic frame” gains more prominence over time, compared to the “human interest frame”. Over these months, CGTN moves from an impartial descriptive approach to one that attributes responsibility variously to both sides, while striving to maintain a neutral overall position.
Analysis of Transport Accessibility and Factors Influencing The Competitiveness of The Ports of Świnoujście and Gdynia
Authors: KLOSKOWSKI Dariusz , ZIMNY Weronika , LIASHUK Vladyslav
Published: January 2025

This study deals with the transport accessibility of the main ports in Poland, which affect the state of the national economy in the statutory sense. The seaports: Świnoujście and Gdynia, acting as the main communication hubs in multimodal transport, are at the same time an important element in global supply chains – they are also strategic points for transshipment of goods and passenger service, combining various branches of transport, including sea, land and rail.

The article presents a comparative analysis of the seaports in Świnoujście and Gdynia, focusing on their transport accessibility and competitiveness in the logistics market. Key aspects, such as the length of the quay, the number of ships served and the volume of container transshipment, are taken into account to ensure a comprehensive result of each port in the context of operational attractiveness.

There are many examples of presenting transport accessibility in the literature on the subject, and many examples are also contained in the literature on the ports themselves. However, in the study, the research was focused on a comparative analysis of the ports themselves as poles in opposing markets in geographical terms.
Attempts To Determine Differences Between Centralized and Decentralized Inter-Organizational Networks with A Focus on Leadership – Selected Research Results of Polish Business Organizations
Authors: Organa Michał
Published: January 2025

The article presents chosen results obtained during the research process focused on Polish organizations involved in inter-organizational networks. Depending on respondents’ opinions, such networks were distinctly discerned as centralized or decentralized. Assuming the existence of significant differences between the functioning of the indicated types of inter-organizational networks based on the analysis of the literature on the subject, the author attempts to recognize such differences more precisely, especially in the context of the benefits achieved with particular emphasis on the influence of leadership implemented in organizations belonging to specific networks. Therefore, the motive for the conducted research is to understand better and specify the differences between centralized and decentralized networks. There is still a significant research gap in the literature on the subject in this area, especially in the context of the forms of leadership dedicated to these networks. The insufficient specification of the differences between centralized and decentralized networks justifies undertaking the research topic and gives them validity. This article aims to diagnose and characterize selected areas that differentiate the functioning of centralized and decentralized inter-organizational networks based on the results of the research conducted on organizations declaring their belonging to a specific type of the considered networks. In addition, the author focuses on determining the nature of the leadership influence implemented in the networks, which is one of the potential key differences in the scope mentioned above. The selection of the study respondents was purposeful and followed the availability rule. Ultimately, a research sample of 102 respondents was obtained, representing Polish organizations belonging to centralized networks (51 people) and decentralized networks (also 51 people). The study was conducted using the CATI (Computer Assisted Telephone Interviewing) method based on an original survey form. Based on the research frame used and the respondents’ answers, it can be assumed that there are differences, but their detailed confirmation requires additional analyses, primarily using statistical methods. Differences between centralized and decentralized networks were observed, especially in the following areas: motives for joining the chosen network system, perception of benefits from participating in a network, and leadership influence perception within the considered networks. The presented results are preliminary analyses and will be developed in subsequent publications.

Authors: AS Ambily , BABY Mobin , SR Sanjith , AM Ajith , S Nivetha , RAJU Krishna S
Published: January 2025

This study explores how soft drink advertisements create a sense of nostalgia among consumers. Nostalgia refers to the longing for or fond remembrance of the past. The research aims to measure the level of nostalgia customers feel after watching such advertisements. A questionnaire was developed to collect responses from people in different age groups and regions, specifically in Kerala, India, and Muscat, Oman.

This research is relevant since it addresses a gap in the literature about how nostalgia works in advertising within Indian and Omani contexts. It highlights that evoking nostalgia can be an effective strategy for soft drink companies, especially in today’s market, where many consumers seek comfort and emotional connection. By creating advertisements that trigger fond memories, brands can foster stronger relationships with their customers and offer emotional relief to those experiencing stress or anxiety.

The study uses descriptive, bivariate, regression, and CFA analyses to understand the impact of nostalgic advertisements on consumers. The findings reveal that these advertisements positively influence customers’ feelings, making them happy and encouraging them to purchase more products. Nostalgic ads also shape consumers’ attitudes toward the brand and prompt them to reflect on their past experiences.

A synthesis of Sphagnum litterbag experiments: initial leaching losses bias decomposition rate estimates
Authors: Teickner Henning , Pebesma Edzer , Knorr Klaus-Holger
Published: January 2025

Abstract. Our knowledge of the magnitude and controls of Sphagnum decomposition rates is derived to a large extent from litterbag experiments that do not explicitly consider initial leaching losses. Previous research on vascular plants suggests that decomposition rate (k0) estimates from litterbag experiments are biased when initial leaching losses (l0) are ignored. In contrast, the magnitude and variability of l0 for Sphagnum litterbag experiments are not well known, and it is therefore also not known how much Sphagnum k0 estimates are biased. As Sphagnum is the main peat-forming species in many northern peatlands, and biases in k0 estimates can propagate and amplify in long-term peatland models, minimizing such bias is necessary for accurate predictions of peat accumulation. We present a meta-analysis of 15 Sphagnum litterbag studies to estimate initial leaching losses (l0), to analyze how much Sphagnum k0 estimates are biased when the decomposition model ignores initial leaching losses and to analyze how much the variance in k0 estimates increases due to initial leaching losses even when they are estimated by the decomposition model. Average l0 estimates range between 3 mass-% to 18 mass-%, and average k0 estimates range between 0.01 to 1.16 yr−1. Simulations and models fitted to empirical data indicate that ignoring initial leaching losses leads to an overestimation of k0. An error analysis suggests that k0 and l0 can be estimated only with relatively large errors because of limitations in the design of most available litterbag experiments. Sampling the first litterbags shortly after the start of the experiments allows more accurate estimation of l0 and k0. We also estimated large l0 (>5 mass-%) for only air-dried samples, which could imply that Sphagnum litterbag experiments with dried litter are unrepresentative for natural decomposition processes in which l0 may be smaller according to leaching experiments with fresh litter. We conclude that comparing results of litterbag experiments between experimental treatments and between studies and accurately estimating decomposition rates may only be possible if initial leaching losses are explicitly considered.

Abstract. The development of high-resolution mapping models for forest attributes based on remote sensing data combined with machine or deep learning techniques has become a prominent topic in the field of forest observation and monitoring. This has resulted in the availability of multiple, sometimes conflicting, sources of information, but, at face value, it also makes it possible to learn about forest attribute uncertainty through the joint interpretation of multiple models. This article seeks to endorse the latter by utilizing the Bayesian model averaging approach to diagnose and interpret the differences between predictions from different models. The predictions in our case are forest canopy height estimations for metropolitan France arising from five different models. An independent reference dataset, containing four different definitions of forest height (dominant, mean, maximum, and Lorey's) was established based on around 5500 plots of the French National Forest Inventory (NFI), distributed across the entire area of interest. In this study, we evaluate models with respect to their probabilities of correctly predicting measurements or estimations obtained from NFI plots, highlighting the spatial variability in respective model probabilities across the study area. We observed significant variability in these probabilities depending on the forest height definition used, implying that the different models inadvertently predict different types of canopy height. We also present the respective inter-model and intra-model variance estimations, enabling us to grasp where the employed models have comparable contributions but contrasting predictions. We show that topography has an important impact on the models spread. Moreover, we observed that the forest stand vertical structure, the dominant tree species, and the type of forest ownership systematically emerge as statistically significant factors influencing the model divergences. Finally, we observed that the fitted higher-order mixtures, which enabled the presented analyses, do not necessarily reduce bias or prevent the saturation of the predicted heights observed in the individual models.

The Structure of Glassy and Liquid Sulfur Revisited
Authors: Benmore Chris
Published: January 2025

High energy x-ray experiments have been performed on liquid and glassy sulfur over a wide temperature range. Heating the elastic quenched glass above -9 ºC and supercooling liquid sulfur below 51 ºC both resulted in crystallization to monoclinic sulfur. The average coordination number of the first shell in glassy sulfur determined from the pair distribution function is found to be 1.90±0.05. This result is in good agreement with previous neutron and x-ray pair distribution function studies, and lends support to the recent proposal that there are a significant number of short chains in the low temperature liquid upon melting. Also, a non-negligible coordination number of 0.20±0.04 is found in the interstitial region between the first and second shells in glassy sulfur, similar to that found in the liquid. An increase in the third peak in the glassy pair distribution function at 4.47 Å associated with S8-rings indicates the percentage is higher in the quenched glass compared to the stable liquid. This casts doubt on previous estimations of the percentage of S8-rings present upon melting.

Improving the efficiency of silicon-based solar cells is imperative to maximise harnessing of solar power. The current improvements in efficiency were attained by better manufacturing techniques and purer materials. There is however indirect evidence that the so-called agglomerated grown-in defects in silicon have a direct impact on cell efficiency and if this is the case, the efficiency could be improved by crystal engineering. This study focuses on understanding the defect generation and growth mechanisms in commercial silicon crystals and their impact on cell efficiency. Silicon wafers from different parts of the crystal having a range of oxygen and dopant concentrations and growth profiles, were investigated. These crystals were characterized using various tools and techniques such as Infrared Light Scattering Tomography (LST) to measure the defect density, and Fourier Transform Infrared Spectroscopy (FTIR) to measure the oxygen concentration. Solar cells were then fabricated out of these wafers to measure the performance of the devices. An understanding of why and how such defects impact the yield of different silicon wafers will lead to a thorough understanding of the relationship between the defect types, size and densities and cell efficiency. Moreover, this study will also shed light on the development of crystal recipes or after-crystal procedures to eliminate or minimize these effects on solar cell performance.

Difenoconazole is a triazole fungicide that inhibits the activity of fungi and is widely used to protect fruits, vegetables and grains. Its health and safety issues need to be further studied. In this study, experiments were conducted to investigate the degradation kinetics and electrochemical degradation pathways of difenoconazole to harmless inorganic products using two electrochemical methods; cyclic voltammetry and constant current electrolysis, in association with UV-Vis spectrophotometric analysis. The results of electrochemical tests indicated the participation of difenoconazole pesticide molecules in charge transfer processes with a priori adsorption of its molecules on the surface of the platinum electrode. UV-Vis spectrophotograms of the pesticide solution indicated a decrease in the absorbance value corresponding to difenoconazole during constant current electrolysis processes. The study elaborates on a mechanism for direct electrochemical degradation of pesticide molecules on the platinum electrode surface.

Sexual extortion of children is a growing global issue in which a perpetrator threatens to distribute intimate material of a victim unless they comply with certain demands. This study systematically reviewed research into the impacts of sexual extortion victimisation on minors. Twelve studies were included, which varied methodologically. Victims of sexual extortion who are under the age of 18 experience diverse short- and long-term impacts, including psychological harm, socio-environmental impacts, financial costs, risk of ongoing victimisation, and offending and criminal justice involvement. These findings support targeted approaches to reduce sexual extortion of minors, while also highlighting the support needs of victims.
The carbon footprint of pasture-based buffalo milk production in Colombia

Colombia’s water buffalo dairy market has experienced significant growth in recent years, emerging as the industry’s leading sector in milk quality and favorable prices. Buffaloes are renowned for their early maturity and ability to produce high-quality meat. Two key characteristics stand out when considering animals for dual- purpose systems: excellent milk quality suitable for sale, calf rearing and strong maternal abilities. A yield gap analysis was conducted to assess the potential for greenhouse gas emissions mitigation in Colombian buffalo systems to identify achievable buffalo milk productivity. This study is adapted to the standards for life cycle assessment, focusing specifically on greenhouse gas emissions from the International Organization for  Standardization. Two functional units were used for measurement: tons of CO 2 -equivalents (CO 2e ) per hectare (ha) and kilograms of CO 2e per kilogram of fat-and-protein-corrected milk (FPCM). Greenhouse gas emissions were calculated using the 2019 Refinement to the 2006 IPCC guidelines, with emission factors sourced from databases. Emissions were categorized into those associated with animals, feces, and soils, with the corresponding sequestration or assimilation accounted in soils, forage biomass, trees, shrubs, and milk production. The simulations were conducted for 550 kg live-weight buffaloes, with a dry matter intake of 11 kg per day alongside 2 kg of balanced feed, under two milk production scenarios: 1500 liters and 3000 liters per lactation. Herd gross energy (GE) intake was calculated using IPCC Tier 2 equations, considering daily gross energy intake per animal category, diet digestibility, and daily net energy requirements for pregnancy, lactation, growth, activity and maintenance. Dry matter intake (DMI) was determined by dividing gross energy intake values by 18.45 MJ of metabolizable energy per kg dry matter, representing the feed’s energy density. These greenhouse gas emissions encompassed methane (CH4) from enteric fermentation and excretions left in paddocks, nitrous oxide (N 2 O) from excretions deposited on pastures and fertilizer application, and carbon dioxide (CO2 ) from lime and urea application, as well as the burning of fossil fuels. The global warming potential indices GWP100 and GWP* were employed to calculate the impact of emissions. Milk carbon footprints (CFs) ranged from 0.7 to 1.41 kgCO2 -eq kg FPCM-1, but when calculated with the GWP* index, they decreased by nearly 35% for both scenarios.

Positive psychotherapy is one of the most comprehensive and effective therapeutic methods in psychoanalytic models. The Balance model of Positive psychotherapy is a key concept that helps not only psychotherapists and clients to detect the problem to plan a route for action but also to build hope for the future life. The study aims to examine the effectiveness of the supervision process of a practical module, “Psychological Counseling with an Individual,” structured on the Balance model of Positive psychotherapy on university students having the module and their actual clients. There were 12 senior-year university students and 12 clients in the supervision process. Evaluation forms for students and clients comprised by the author were used as collection tools. The outcomes showed that including the Balance model in the sessions helped understand the psy

Guerra y cárcel. El encierro y proceso de Amelia Azarola y la rebelión de las mujeres presas el 4 de noviembre de 1936
Authors: Mata y Martín Ricardo
Published: January 2025

El trabajo muestra una situación particular de uso del encierro penal durante la guerra civil española (1936-1939), que tiene a su vez algún reflejo de lo que sucedía de manera más amplia. Amelia Azarola fue una joven navarra de familia republicana que antes de la Segunda República había formado parte del movimiento estudiantil de protesta. Llegado este régimen participó en las manifestaciones populares de bienvenida al nuevo régimen. Terminó la carrera de medicina y realizó la tesis doctoral con el Dr. Juan Negrín. Después se casó con Julio Ruiz de Alda, también navarro, héroe del vuelo trasatlántico del Plus Ultra y uno de los fundadores de Falange. Iniciada la Guerra civil fue encarcelada en Madrid y allí conoció la noticia del asesinato de su marido en la Cárcel Modelo. Estando en la cárcel de Conde de Toreno se preparó por las milicias una saca de presas, entre las que se encontraba seleccionada ella misma. Ese 4 de noviembre de 1936 se produjo un motín para evitar la saca, hecho excepcional que no cuenta con precedentes ni otros casos semejantes durante todo el periodo bélico. A propósito del caso de Amelia veremos la intervención del Cuerpo Diplomático presente en Madrid en este tipo de temas carcelarios en los primeros meses de la guerra. Después fue trasladada de centro de reclusión, procesada por desafección al régimen y continuó su periplo carcelario.
