Authors: Nezhad Iman Eskandari , Ataei Mohammad , Sereshki Farhang
Published: December 2024

Operations research is a science that is used in various fields. This science is a set of quantitative techniques that help managers make decisions using scientific methods. This science is related to many axial decision-making issues of managers. For this reason, it is also called the science of management. This science is widely used in industries and mines. One of the most appropriate methods for solving research problems in operations is using linear programming in mining projects. This study was conducted in the Sangan iron ore mine in Iran. In this article, by using linear programming modeling and solving the transportation problem, the allocation of iron ore to feedstock concentrate plants from multiple sources to multiple destinations has been done considering the uncertainty of the grade. This paper is in the field of studying and identifying the quantitative and qualitative amount of extractable iron ore reserves in the mines, and on the other hand, the needs of concentrate plants concerning their feedstock supply by considering the uncertainty of iron ore grade in mines and deciding on their proper allocation. Mineral modeling and estimation of the amount of extractable minerals have been done using the block model. Uncertainty of iron ore grade in the block model is investigated using the sequential Gaussian simulation method. The amount of mining capacity and its sequence is planned considering the type of iron ore used in the plans during 5-year periods. In this article, the modeling of the problem has been done by considering the existing limitations in mines, such as the amount of supply, grade of iron ore, iron oxide and sulfur. On the other hand, the limitations in plants, such as demand, type and grade of iron ore, iron oxide and sulfur are considered in the modeling. In the end, the amount of iron ore tonnage sent from each mine to each plant during 5 years is presented by solving the problem.
SHALLOW SUBSURFACE STRUCTURES AND QUATERNARY DEFORMATIONS ON THE EASTERNMOST MATANO FAULT, INDONESIA, REVEALED BY ELECTRICAL RESISTIVITY TOMOGRAPHY

Published: December 2024

In active fault studies, electrical resistivity tomography (ERT) with wide electrode spacing (10 m) and fewer than 60 electrodes is typically utilized. However, this configuration limits the ability of ERT to resolve detailed geological information, such as fault geometry and motion, small-scale offset, and thickness of Quaternary layers. High-resolution electrical resistivity tomography (ERT) with narrow electrode spacing (1.5‒5 m) and 112 electrodes offers an opportunity to uncover finer geological information. This study combines ERT measurements with geological data from trenches and field observations to investigate the subsurface structures and Quaternary deformation on the easternmost Matano fault. On ERT sections, the easternmost Matano fault is characterized by deformed resistivity layers and resistivity contrasts. The subsurface fault structures dip steeply and indicate reverse and normal motions for the vertical component, with the displacement related to the Quaternary faulting ranging from 3 to 26 m. Notably, fault structures on ERT sections are not necessarily expressed by geomorphic features, suggesting obscured tectonic features. This study demonstrates the reliability of high-resolution electrical resistivity tomography (ERT) in unveiling geological information, such as fault location and geometry, fault vertical motions, buried fault structures, small-scale vertical offsets, stratigraphy, and Quaternary sediment thickness, which are essential for seismic hazard assessment.
NEW DASYCLADAL ALGAE FROM THE ANISIAN (MIDDLE TRIASSIC) OF LIKA (CROATIA)
Authors: Grgasović Tonći
Published: December 2024

Two new species of dasycladal algae are described from the Anisian limestones of the Lika region in Croatia. Griphoporella? speleoluka n. sp. is characterized by very small cylindrical thallus and vesiculiform laterals arranged in close whorls. In consecutive whorls, laterals are positioned one above the other. It differs from other species by smaller dimensions and the arrangement of the laterals. Palaeodasycladus primus n. sp. has cylindrical thallus with whorls of inclined laterals up to the third order. Primary laterals are not completely calcified, producing so-called intusannulation. Trichoform or tubular secondary laterals bear bundles of thin, probably trichoform, tertiary laterals. Both of the new species have been found within typical Anisian microfossil assemblage.

Published: December 2024

In recent years, numerous studies have employed deep learning in seismology, with data-driven neural network models increasingly becoming the norm in emerging research paradigms. Alongside advancements in model architectures, several benchmark datasets have also been introduced. However, many of these datasets suffer from imbalanced distributions, particularly a scarcity of large-magnitude events, which can impair the performance of deep learning-based models. Taiwan, situated in a seismically active region experiences a high frequency of earthquakes annually. The Central Weather Administration (CWA) in Taiwan maintains comprehensive records of these seismic events. This study introduces a benchmark dataset, named CWA, specifically compiled from this extensive database. The CWA benchmark includes 331 events with magnitudes greater than five, collected from a high-density seismic network spanning from 2011 to 2021, making it well-suited for training deep learning models. In addition, the CWA benchmark features over 40 attributes and ∼500,000 seismograms, providing valuable data labels for various seismology-related tasks.

Authors: Brehmer Jonas R. , Kraus Kristof , Gneiting Tilmann , Herrmann Marcus , Marzocchi Warner
Published: December 2024

Testing earthquake forecasts is essential to obtain scientific information on forecasting models and sufficient credibility for societal usage. We aim to enhance the testing phase proposed by the Collaboratory for the Study of Earthquake Predictability (CSEP, Schorlemmer et al., 2018) with new statistical methods supported by mathematical theory. To demonstrate their applicability, we evaluate three short-term forecasting models that were submitted to the CSEP-Italy experiment, and two ensemble models thereof. The models produce weekly overlapping forecasts for the expected number of M4+ earthquakes in a collection of grid cells. We compare the models’ forecasts using consistent scoring functions for means or expectations, which are widely used and theoretically principled tools for forecast evaluation. We further discuss and demonstrate their connection to CSEP-style earthquake likelihood model testing, and specifically suggest an improvement of the T-test. Then, using tools from isotonic regression, we investigate forecast reliability and apply score decompositions in terms of calibration and discrimination. Our results show where and how models outperform their competitors and reveal a substantial lack of calibration for various models. The proposed methods also apply to full-distribution (e.g., catalog-based) forecasts, without requiring Poisson distributions or making any other type of parametric assumption.

Water quality is an important factor in aquaculture activities, including goldfish (Carassius auratus) farming. One approach to improving water quality is the use of nanofilters. This study aims to evaluate the performance of nanofilters made from Sargassum sp. with the addition of copper oxide nanoparticles. The method used involves the fermentation of bacterial cellulose from Acetobacter xylinum using Sargassum sp. extract as a medium, followed by homogenization and the addition of CuO-NPs at concentrations of 0.5%, 1%, and 1.5%, and subsequent oven drying. The nanofilter membrane will then be analyzed using SEM, XRD, and FTIR to characterize its properties. Performance tests will assess the quality of water used in goldfish farming, including pH, TOM, TDS, and TSS after treatment with the nanofilter. Morphological results show a rougher and denser surface with dispersed CuO-NPs. Characterization reveals cellulose I with crystallinity values ranging from 86.80% to 90.20%, with functional group peaks at 3145, 2927, and 1735 cm⁻¹ indicating cellulose characteristics, and a peak at 424 cm⁻¹ indicating Cu-O bonds. Statistical analysis of performance tests on the water quality of goldfish farming in the F-test shows significant differences (p

Published: December 2024

Fuel derived from crude vegetable oil, such as coconut oil, holds promise as an alternative energy source to mitigate the increasing reliance on fossil fuels driven by population growth and industrial activities. The experiment involved suspending a single droplet of crude coconut oil mixed with activated carbon from areca shell waste and placed at the junction on R-type thermocouple (Pt/Pt-Rh13%). The droplets were ignited using a hot wire and subjected to atmospheric pressure and room temperature. Coconut oil comprises a saturated triglyceride carbon chain compound of approximately 91%, and areca shell waste possesses a porous structure that fosters favorable interactions between fuel molecules. The droplet combustion method was selected to streamline the process and enhance the contact area between air and fuel, thereby boosting the reactivity of fuel molecules. The research found that adding activated carbon shortens the carbon chain, making it more reactive and easier for the fuel to ignite. Specifically, activated carbon significantly enhances fuel performance at a concentration of two parts per million (ppm). At this level, the fuel absorbs heat more effectively and ignites faster compared to one ppm and three ppm levels. Moreover, the results show that heat absorption occurs slowly at one ppm, while at three ppm, the increased molecular mass of the fuel can strengthen carbon-bonding forces. These factors contribute to a longer ignition time for the fuel. The findings suggest that the activated carbon from areca shell waste can play a good role as a combustion catalyst, where overall, fuel performance increases.

Published: December 2024

One common bio-ceramic material used in the biomedical industry is hydroxyapatite. Because of its crystallographic and molecular resemblance to the hard tissues of the human body, hydroxyapatite is thought to form. Scallop shells are one natural source of hydroxyapatite, which is high in calcium. This study examines how the calcination temperature affects the characteristics of hydroxyapatite made from leftover scallop shell. Hydroxyapatite was synthesized via the sonochemical method, with calcination conducted at temperatures of 900°C, 1000°C, and 1100°C. The hydroxyapatite that was prepared was assessed using X-ray diffraction (XRD) to determine the phase and crystallite size, Scanning Electron Microscopy (SEM) to conduct a morphological investigation, and Fourier Transform Infrared (FTIR) spectroscopy to conduct a functional group analysis. Phases resulting from varying calcination temperatures include hydroxyapatite and β-tricalcium phosphate. The crystallite size of hydroxyapatite enhanced with rising temperature. The morphology of hydroxyapatite exhibited agglomeration in all samples, with grain size escalating alongside the increase in calcination temperature. The functional groups generated under the three temperature fluctuations include O-H, P-O, PO43-, and O–P–O groups. The calcination temperature significantly influences the characteristics of produced hydroxyapatite and impacts its biocompatibility as a bone implant material.

Published: December 2024

This research investigates the influence of varying proportions of natural polymers on the fire-retardant properties of bioplastic. Tapioca starch (Manihot esculenta) and corn starch (Zea mays) were selected as the bioplastic materials, with different weight fractions employed in the analysis. These materials, as naturally occurring polymers, are biodegradable and serve as promising components in the development of bioplastics. Fire resistance testing was conducted in accordance with ASTM D635-03, utilizing weight ratios of tapioca to corn starch at 70:30, 60:40, and 50:50. The results included photographic documentation of each specimen alongside the corresponding outcomes from the fire resistance tests. These images provide insight into the physical condition of the specimens prior to testing, emphasizing any notable morphological features that may affect their fire resistance properties. The optimal burning rate was observed in the bioplastic with a 50:50 weight fraction ratio of tapioca starch to corn starch, which exhibited a combustion rate of 8.420 mm/s. Additionally, the bioplastic with the highest weight loss rate, recorded at 0.0346 g/s, was also composed of a 50:50 weight fraction of the two starches. The observed increase was 2.36% relative to the 60:40 weight fraction and 13% relative to the 70:30 weight fraction. This increased weight loss rate can be attributed to the higher corn starch content, which is characterized by inherent flammability due to its structural composition.

Published: December 2024

Global energy consumption has surged due to the population's rapid growth, leading to a switch to using renewable and clean energy. Among various strategies for developing renewable and clean energy, biomass pyrolysis emerged as attractive, and microwave irradiation pyrolysis is a prominent technique. This research aims to determine the ideal parameters for microwave-assisted pyrolysis of Spirulina platensis (SP) microalgae in order to produce high-value liquid products with the addition of activated carbon (AC) additives. Liquid bio-oil products were characterized concerning their calorific value, chemical bonds, and thermal stability. This research also investigates product distribution as a function of AC loading. Using 900W output power of microwave and 550 °C pyrolysis temperature, the pyrolysis process was shortened by 36.5% at 15% of AC loading. At 20% AC loading, the pyrolysis duration was shortened by 33%. This study demonstrated that the highest liquid and minimum solid residue were obtained at 20% AC loading. The heating value of liquid bio-oil with no AC additives was 35.419 MJ/kg, while at a 10% AC additive was 37.464 MJ/kg. The highest heating value was found at a 15% AC additive, which was 39.345 MJ/kg; meanwhile, at a 20% AC additive, it was 36.097 MJ/kg. These findings conclusively showed that the liquid bio-oil's quality was significantly improved by the addition of activated carbon (AC), establishing it as an attractive option for the microwave-assisted pyrolysis (MAP) process that produces advanced renewable fuels.

Authors: Tran Ket
Published: December 2024

Purpose:

Evaluation of safety, efficacy, and patient satisfaction after PresbyMAX surgery

Methods

In private clinical practice, twenty-five presbyopic patients (28% males, 72% females), the average age is 40.72 ± 3.14. The dominant eye was fully corrected for distance vision; the non-dominant eye was corrected using central PresbyMAX monocular mode. Binocular uncorrected distance visual acuity (BUDVA), near visual acuity (BUNVA), and intermediate visual acuity (BUIVA) were monitored at 1 week, 1 month, and 3 months after surgery.

Result:

In this study, The mean Preoperative spherical equivalent was -3,27 ± 1,16. The mean Preoperative visual acuity was 1 ± 0,02. The BUDVA at 1 month postoperatively was 0,11 ± 0,09, the BUNVA was 1,96 ± 0,35, and BUDVA was equal to or better than 20/25 and 20/32 in all patients, 64% and 96%, respectively. Near vision J2 or better was achieved at 96%. Only 2 patients (8%) felt passable after surgery. The main unpleasant symptoms were blurred vision and glare.

Conclusions:

PresbyMAX monocular presbyopia correction combined with standard monocular LASIK in the other eye is a safe and acceptable procedure in older patients with refractive error.
Assessing Whether Women's Unique Needs and Persistent Disparities in Mental Health Care Are Being Addressed by Emerging AI-Powered Digital Health Solutions
Authors: Kasen Perri , Nguyen Julie , Hildreth Christine , Chapple Emily , Donaldson Kira , Eslami Natasha , Garfield Susan
Published: December 2024

Background: Mental health is a growing challenge, with women and girls disproportionately affected by conditions including anxiety and depression. These disparities are driven and exacerbated by factors such as socioeconomic status, race, and access to healthcare. Standards of care for these conditions vary, including combinations of in- and out-patient psychotherapy, pharmacotherapy, and behavioral therapies. Patients’ access to care is impacted by multifaceted system and individual level challenges, including provider shortages, cost, health literacy, and scheduling, with minority, economically disadvantaged, and neurodiverse women facing even greater barriers. Innovative digital health tools using artificial intelligence (AI) have the potential to address care gaps and narrow disparities for women and other vulnerable groups.

Methods: A systematic review of available technologies was conducted to identify current AI solutions and digital health interventions focused on depression, anxiety, or overall mental wellbeing. A solution taxonomy was developed based on similar AI-enabled services. The solutions were categorized based on intervention modality, disease focus, target population, realized outcomes, and business model. The solution’s intent and ability to address mental health challenges for women was then assessed.

Results: Current patient-facing mental health solutions include conversational AI support, healthy habit formation support, personalized care plans, screening tools, biometric risk factor identification, and digital music therapy. Among the examined technologies, 3 of 23 (13%) were designed for women and girls, and two of those solutions focused on women’s reproductive years. Just over half of assessed solutions (52%) use business-to-business-centric business models, requiring employers, payers, or providers to enable access.

Conclusions: AI-driven approaches can complement traditional mental health services by providing targeted education, improved access, and personalized care. Despite the potential to reduce gender disparities in mental healthcare, most AI solutions do not specifically address the needs of women and girls. Opportunities for greater impact include tailoring interventions to better suit women from diverse backgrounds, improving access through business model innovation, and expanding clinical integration in alignment with evidence-based treatment. Future research should focus on the long-term impact of AI interventions on mental health outcomes, designing specific tools for women and girls, and the risk of exacerbating biases by using AI in mental healthcare.

Published: December 2024

Background: Hospital Score is a well-known and validated tool for predicting readmission risk among diverse patient populations. Integrating social risk factors using natural language processing with the Hospital Score may improve its ability to predict 30-day readmissions following an acute myocardial infarction. Methods: A retrospective cohort included patients hospitalized at Vanderbilt University Medical Center between January 1, 2007, and December 31, 2016, with a primary index diagnosis of acute myocardial infarction, who were discharged alive. To supplement ascertainment of 30-day readmissions, data were linked to Center for Medicare & Medicaid Services (CMS) administrative data. Clinical notes from the cohort were extracted, and a natural language processing model was deployed, counting mentions of eight social risk factors. A logistic regression prediction model was run using the Hospital Score composite, its component variables, and the natural language processing-derived social risk factors. ROC comparison analysis was performed. Results: The cohort included 6,165 unique patients, where 4,137 (67.1%) were male, 1,020 (16.5%) were Black or other people of color, the average age was 67 years (SD:13), and the 30-day hospital readmission rate was 15.1% (N=934). The final test-set AUROCs were between 0.635 and 0.669. The model containing the Hospital Score component variables and the natural language processing-derived social risk factors obtained the highest AUROC. Discussion: Social risk factors extracted using natural language processing improved model performance when added to the Hospital Score composite. Clinicians and health systems should consider incorporating social risk factors when using the Hospital Score composite to evaluate risk for readmission among patients hospitalized for acute myocardial infarction.
Natural health products for treatment of metabolism dysfunction-associated steatotic liver disease
Authors: Chan Catherine
Published: December 2024

Metabolism dysfunction-associated steatotic liver disease affects approximately 30% of the world’s population, yet there is only one approved treatment option applicable to more advanced disease. Many individuals consume natural health products for general health and a variety of medical conditions but none are recommended for metabolism dysfunction-associated steatotic liver disease in current European or American guidelines. Nevertheless, human trials indicate that some of these products may be efficacious for treatment of metabolism dysfunction-associated steatotic liver disease and these are supported by mechanistic studies using animal models. This narrative review aims to highlight recent research in human and animal trials on selected natural health products. So far, neither probiotics nor omega-3 polyunsaturated fatty acids have produced convincing, consistent benefits in human randomized controlled trials although studies in mouse models suggest that they have actions can lead to reduction of hepatic steatosis or other markers, such as liver enzymes. Two of the many polyphenols that have been studied were also reviewed here. Trials with resveratrol in humans have not yielded significant results whereas curcumin, the active ingredient in turmeric, appeared to consistently lower steatosis or liver enzymes. Both compounds reduced steatosis in rodent models of MASLD, involving a variety of mechanisms including anti-oxidant, anti-inflammatory and metabolic effects. More, better-designed and powered human trials are required to provide convincing evidence of efficacy of most natural health products.

Nitric oxide -- superoxide cooperation in the regulation of renal Na(+),K(+)-ATPase.
Authors: Bełtowski Jerzy , Marciniak Andrzej , Jamroz-Wiśniewska Anna , Borkowska Ewelina
Published: December 2024

The aim of this study was to investigate whether endogenous superoxide anion is involved in the regulation of renal Na(+),K(+)-ATPase and ouabain-sensitive H(+),K(+)-ATPase activities. The study was performed in male Wistar rats. Compounds modulating superoxide anion concentration were infused under general anaesthesia into the abdominal aorta proximally to the renal arteries. The activity of ATPases was assayed in isolated microsomal fraction. We found that infusion of a superoxide anion-generating mixture, xanthine oxidase (1 mU/min per kg) + hypoxanthine (0.2 mumol/min per kg), increased the medullary Na(+),K(+)-ATPase activity by 49.5% but had no effect on cortical Na(+),K(+)-ATPase and either cortical or medullary ouabain-sensitive H(+),K(+)-ATPase. This effect was reproduced by elevating endogenous superoxide anion with a superoxide dismutase inhibitor, diethylthiocarbamate. In contrast, a superoxide dismutase mimetic, TEMPOL, decreased the medullary Na(+),K(+)-ATPase activity. The inhibitory effect of TEMPOL was abolished by inhibitors of nitric oxide synthase (L-NAME), soluble guanylate cyclase (ODQ) and protein kinase G (KT5823). The stimulatory effect of diethylthiocarbamate was not observed in animals pretreated with a synthetic cGMP analogue, 8-bromo-cGMP. An inhibitor of NAD(P)H oxidase, apocynin (1 mumol/min per kg), decreased the Na(+),K(+)-ATPase activity in the renal medulla and its effect was prevented by L-NAME, ODQ or KT5823. In contrast, a xanthine oxidase inhibitor, oxypurinol, administered at the same dose was without effect. These data suggest that NAD(P)H oxidase-derived superoxide anion increases Na(+),K(+)-ATPase activity in the renal medulla by reducing the availability of NO. Excessive intrarenal generation of superoxide anion may upregulate medullary Na(+),K(+)-ATPase leading to sodium retention and blood pressure elevation.
Combined effects of radiotherapy and photodynamic therapy on an in vitro human prostate model.
Authors: Colasanti Alberto , Kisslinger Annamaria , Quarto Maria , Riccio Patrizia
Published: December 2024

Human prostate cancer cells were evaluated for growth after photodynamic therapy, radiotherapy, and combined treatment. Indocyanine green was tested as a photosensitizer and radiosensitizer. Two human cell lines were used: PC-3 derived from prostate carcinoma, and EPN derived from normal prostate tissue. The light source used for the photoactivation experiments was a diode laser peaked at 805 nm. The light dose incident on cells was 108 J/cm(2). Ionizing radiation was produced by a linear accelerator, and the dose was 2, 4 and 6 Gy. Cytotoxicity was evaluated by measuring the colony forming ability of cells. Our results show that indocyanine green induces cell death by photoactivation, but it does not act as a radiosensitizer if used with ionizing radiation. The combined treatment of photodynamic therapy and radiotherapy produces an additive effect which does not depend on the sequence of the two treatments. Combined treatments could be more useful since they allow the reduction of the ionizing radiation dose to obtain the same effect as one obtainable by radiotherapy alone.
The emergence of biological homochirality

Published: December 2024

The homochirality of biological molecules is one of the basic mysteries of biogenesis. The predominance of l-amino acids and d-hydrocarbons in living matter stands in contrast to the chemical principle of symmetry between enantiomers. An answer to the puzzle needs to include a plausible explanation of how the natural racemic balance was initially tipped in favor of one enantiomer and how the initial tiny excess was amplified to significant levels. It is also necessary to consider how the imbalance was sustained from returning to a thermodynamic equilibrium. This is a review of the main concepts and observations, followed by a brief discussion.

Introduction: In recent years, exposure to nanomaterials has been known as a challenge among occupational health experts. In this line, personal protective equipment has been considered as a solution to reduce the worker’s exposure. Since respiratory and skin tracts represent the most common workplace exposure routes, knowledge of the efficiency of respiratory and skin protection equipment is particularly important. So, the aim of this study is the assessment of the efficiency of respiratory and skin protection equipment toward controlling nanoparticles in the workplace with a scoping review approach.
Material and Methods: This study was conducted in 2022 with a scoping review approach. Arksey and O’Malley’s five-step framework was chosen as the research method. The search strategy was followed in the databases necessary to access the research data, including PubMed, Google Scholar, Science Direct, Web of Science, and Scopus. Also, EndNote X9® and Microsoft Excel software were used to collect and analyze studies, respectively.
Results: In the first step, 1014 articles were identified. Finally, 38 articles were included in the study to examine quantitative and qualitative information about the efficiency of respiratory and skin protective equipment. Twenty-five articles were related to breathing masks, and six studies were about protective gloves, and seven other articles were devoted to protective clothing. According to the studies of breathing masks, the mean total penetration of nanoparticles was estimated at 2.27%. Also, based on the studies of protective clothing, the maximum penetration of nanoparticles was 30nm for protective clothing made of polypropylene and polyethylene with different layers.
Conclusion: Although the efficiency of existing personal protective equipment showed a good result for controlling nanoparticles, the size of nanoparticles is one of the essential parameters in determining the efficiency of the equipment, which should be considered the workplaces. So, it is recommended that more studies be considered to improve their efficiency, and standard tests should be developed to evaluate them.

Published: December 2024

Due to the importance of the deposit money bank to the Nigerian Economy that liquidity level and status of this sector is not only important to the investors, the bank itself but also to the economy at large. Based on this challenge this study examines into the impact of bank liquidity on financial performance of deposit money banks in Nigeria. The secondary data was sourced from the audited financial statement of deposit money banks from 2018 to 2022. The study employed the static panel regression analysis to determine the relationship between liquidity ratio, loan-to-deposit ratio and bank size and financial performance measures. The findings from model one reveals that loan-to-deposit ratio and liquidity ratio has negative and positive significant effect on earnings per share, while loan-to-deposit ratio, liquidity ratio and bank size has negative significant effect on net interest margin.  It is therefore recommended that deposit money banks should carefully manage their loan-to-deposit ratios to avoid excessive lending that could negatively impact earnings per share. Institutions should focus on improving their liquidity ratios by maintaining sufficient liquid assets to meet short-term obligations. Enhancing liquidity management practices can positively affect earnings per share, boosting overall financial performance and shareholder value. Regularly monitoring and adjusting these ratios will ensure a balanced approach to lending and liquidity, supporting sustainable growth and profitability. Additionally, financial institutions should provide ongoing training and resources to their teams to strengthen risk management and financial planning.

Published: December 2024

Despite the unique role expected to be played by small and medium scale enterprises in every economy and Nigeria inclusive. The contribution of SME’s to economic growth and development is still retarding, which could be due to two major reasons which are intrinsic/ controllable factors and extrinsic/uncontrollable factors. This study examined the impact of financial technology on small and medium scale enterprises performance in Nigeria. The ex-post factor research design was employed. The secondary data was sourced from the audited financial statement of the small and medium scale enterprises and Central Bank Statistical Bulleting from 2019 to 2023. The ordinary least square regression was employed to determine the relationship between return on equity, sales growth and automated teller machine, web-pay, mobile money payment.
The findings reveals that automated teller machine and point-of-sale has negative significant effect on return on equity (β: -1.78; t:-0.11) and (β: -0.75; t:-0.08). Also, web-pay and point of sale has negative significant effect on sales growth at (β: -0.05; t: -0.61) and (β: -1.11; t: -0.40) while mobile money payment has positive significant effect on sales growth (β: 0.65; t: 0.30).  It is therefore recommended that SME’s should consider optimizing their electronic payment systems, focusing on cost-reduction strategies and enhancing the efficiency of ATM, web pay, and POS channels. Additionally, exploring alternative payment solutions or investing in technology upgrades to streamline transaction processes may mitigate the negative impact on profitability, helping firms to better align these systems with their financial objectives.
The emergence of gender equality legislation in the Faroe Islands: A discursive study
Authors: Hayfield Erika Anne , Vágsheyg Jórun
Published: December 2024

This article concerns the emergence of gender equality legislation and public discourse on gender equality in the Faroe Islands. The article examines which gender equality discourses and underlying gender ideologies are evident in the Faroe Islands. We commence our study in 1980, when public debate on gender equality legislation intensified. Methodologically, we apply critical discourse analysis in our analysis of newspaper articles, interviews, public documents, and parliamentary debates. Taking an island perspective, we examine tensions between being an island context, on the one hand, and being Nordic on the other. Three discourses emerged from our inductive analysis, which relate to certain time-periods: 1) navigating the concept of gender equality in a religious small-island society, 2) gender equality in the context of (Faroese) identity and 3) the (ir)relevance of gender equality in the Faroe Islands. In the discussion, we argue that gender equality ideologies have evolved and transformed over time in constant interaction with Faroese identity, islandness, and the outside world. We identify gender equality ideologies of traditionalism, religious essentialism, and egalitarianism in our early time period. Subsequently, more recent ideologies of liberal egalitarianism, feminist egalitarianism, neotraditionalism and flexible egalitarianism are identified.

Greinin snýr seg um, hvussu javnstøðulógin varð til, og um almenna diskursin um kynjajavnstøðu í Føroyum. Greinin viðger hvørjir kynjajavnstøðudiskursar og undirliggjandi kynjahugsjónir eru sjónligar í Føroyum. Viðgerðin strekkir seg fra 1980, tá ið almenni diskursurin viðvíkjandi javnstøðulóggávu øktist. Vit nýta kritiska diskursanalysu til at greina tíðindablaðgreinar, samrøður, almenn skjøl og kjak á tingi. Frá einum oyggjasjónarmiði greina vit spenningin millum oyggjakontekstin øðrumegin og tann norðurlendska kontekstin hinumegin. Í tí induktivu viðgerðini eyðmerkkja vit tríggjar diskursar, ið hvør sær knýta seg at ávísum tíðarskeiðum: 1) naviger-ing av kynjajavnstøðuhugtakinum í einum átrúnaðarligum smáoyggjasamfelag, 2) kynjajavnstøða úr einum (føroyskum) samleikakonteksti, og 3) týdningurin av kynjajavnstøðu í Føroyum. Í kjakinum vísa vit á, at kynjajavnstøðuhugsjónir eru mentar og broyttar yvir tíð í áhaldandi ávirkan millum føroyska samleikan, oyggjakontekstin og tann ytra heimin. Í tí fyrra tíðarskeiðnum eyðmerkja vit hugsjónirnar traditionalismu, átrúnaðarliga essentialismu og egalitarianismu. Í tí seinna tíðarskeiðnum eyðmerkja vit hugsjónirnar liberala egalitarianismu, feministiska egalitarianismu, neotraditionalismu og fleksibla egalitarianismu.
