Evaluating the Impact of Value-Added Tax on Economic Growth, Inflation, Unemployment, and Consumer Behaviour in Developing Countries: Evidence from Indonesia
Authors: Fadillah Lia , Gunarto Muji , Helmi Sulaiman
Published: February 2025

Value-Added Tax (VAT) is a major source of government revenue in many developing countries, including Indonesia. This research aims to evaluate the impact of VAT on economic growth, inflation, unemployment, and consumer behavior in Indonesia. The study utilizes secondary data from 2000 to 2023, encompassing various economic indicators. The results of the analysis indicate a significant relationship between VAT policies and these indicators, though the outcomes vary depending on specific contexts. This research concludes that VAT policies require comprehensive evaluation to minimize negative impacts and maximize benefits. The study reveals a significant negative relationship between VAT rates and GDP growth, where each unit reduction in VAT rates corresponds to an increase in economic output. Similarly, higher VAT rates demonstrate a positive but limited effect on inflation, reflecting the pass-through effect of VAT on consumer prices. Additionally, a strong positive correlation emerges between VAT rates and unemployment, highlighting its potential to suppress labor market dynamics. Lastly, household consumption is highly responsive to VAT adjustments, underscoring its role as a critical factor. The study concludes that high VAT rates can hinder economic growth, exacerbate inflation, and increase unemployment in developing countries like Indonesia. It recommends policies emphasizing the optimization of VAT rates to balance revenue collection with sustainable economic expansion and socioeconomic stability. This research provides valuable insights for policymakers and contributes to the global discourse on tax policies and economic development.

Authors: Wan Mustapha Wan Zumusni , Kamaruzaman Nur Zafifa
Published: February 2025

Previous studies have found the detrimental effect of polygamy on children and wives. This paper presents the dynamics of polygamy and its impacts on the family members. Data collected include content analysis on a documentary about a polygamous family staying on the East Coast, Malaysia. Data also involve observations and in-depth interviews with the informants, namely the husband, his first and second wife and his children from the first marriage. The findings unearth four themes that emerged in the psyche: the psychological and emotional impacts, family function, the wives’ marital satisfaction, and the coping strategies of each family member. Findings suggest that despite the husband’s claims that the family is functioning well, the wife’s and children’s experiences are otherwise. The challenges discovered include equality practices, especially in dividing resources and affections, managing conflicts and disagreements, and practising open communication among the family members. The husband, wives, and children share their predicament and how polygamy affects their well-being and emotions. There are also possible symptoms of disturbed mental health uncovered among the informants.

Dalits, Reform, and the Brahmin Social World in Viswanatha Satyanarayana’s Nīla Peṇḍli
Authors: Kodakandla Nitin
Published: February 2025

The nineteenth and twentieth centuries witnessed the rise of social reform as a transformative force in Indian society, challenging entrenched caste hierarchies and reconfiguring social relationships. Viswanatha Satyanarayana’s novels, deeply engaged with the issues of social reform and the politics of modernity and tradition, have however remained largely overlooked in social science research. Through a critical reading of Viswanatha’s Nīla Peṇḍli from a social science perspective, this article makes a start in engaging with his political thought. Nīla Peṇḍli portrays the relentless advance of social reform and interrogates the eagerness with which society is embracing it without considering its consequences. By examining conservative responses to social reform and Dalit assertion, this article throws light on the anxieties of the Brahmin conservatives in the face of these changes, and the discursive strategies they adopt to negotiate and be relevant in a changing world.
Neuron-Astrocyte Interactions in Aging and Alzheimer's Disease: Dysregulation of Amyloid Precursor Protein
Authors: Jáuregui Gretsen Velezmoro , Parpura Vladimir
Published: February 2025

Amyloid precursor protein (APP) is central to Alzheimer's disease (AD) by its role in Aβ build-up and in neuronal and astrocytic malfunction. The major risk factor for late-onset AD is aging, which increases APP processing in both neurons and astrocytes, and consequently increases Aβ production. This focused review covers the subjects of how aging and AD affect APP dynamics within the both cell types and how astrocytes dysfunction can enhance neuroinflammation and neuronal dysfunction and injury. We discuss the interplay between neurons and astrocytes in aging and AD brains, where bi-directional cellular interactions accelerate neurodegeneration.
Keywords: Amyloid precursor protein, Alzheimer`s disease, amyloid beta, aging, astrocytes, neurons, neuroinflammation, reactive astrogliosis

Published: February 2025

Anxiety in pregnant women can affect the labor process due to the psychological instability that occurs. Self-efficacy is one of the factors that can reduce anxiety in pregnant women. This study has a general objective of analyzing the relationship between self-efficacy and anxiety in third trimester primigravida pregnant women in agricultural areas. This study uses correlational quantitative research with a cross-sectional survey design approach. The sample consisted of 83 respondents, selected through non-probability sampling, specifically total sampling. The research instrument for measuring the level of self-efficacy was a self-efficacy questionnaire, and the level of anxiety was measured using the Pregnancy Related Anxiety Questionnaire-Revised 2 (PRAQ-R2). Data were analyzed using Kendall's Tau-b test, and the results obtained (p-value = 0.000, p < 0.05) showed a relationship between self-efficacy and anxiety in third trimester primigravida pregnant women. Self-efficacy affects the mother's mentality during pregnancy and childbirth because high confidence in her abilities makes her more motivated to maintain her health and feel satisfaction during the childbirth process. Pregnant women with high self-efficacy may better withstand reactions that trigger anxiety because they can solve problems using their abilities and think positively about situations. The conclusion obtained is that most respondents had high levels of self-efficacy and mild anxiety levels, and there is a relationship between self-efficacy and anxiety in third trimester primigravida pregnant women.
Keywords: Anxiety, Pregnant Women, Primigravida, Self-Efficacy, Third Trimester
Synergy of specialized medical training and regenerative medicine treatments: how to strengthen and optimize the natural healing processes of sports injuries
Authors: Gawda Piotr
Published: February 2025

Tissue injuries initiate specific healing processes, which are sequentially: inflammatory, regenerative, and tissue remodeling, and these are time-consuming. Additionally, the natural response to injury is reduced physical activity, which in turn weakens anabolic signaling, disrupting mechanotransduction mechanisms. Through appropriate therapeutic intervention, we can modulate these processes, accelerating and simultaneously optimizing the healing process without risking re-injury.

One solution to avoid stagnation in training is the use of occlusion exercises. By controlled introduction of the injured tissue to stress, using low loads with partially restricted arterial blood flow and complete venous outflow occlusion, we allow the influx of pro-inflammatory factors without further damaging the tissue structure. This accelerates and stimulates the body’s natural healing and repair cycles, such as lactate accumulation, pH increase, and enhanced anabolic signaling, which triggers growth and remodeling.

Such an intensified process requires collagen supplementation, providing the essential building material for faster and safer regeneration of injuries. Collagen presence supports the reconstruction of tissue structure, which is crucial for restoring full functionality post-injury.

Thanks to modern diagnostic ultrasound methods, it is possible to inject collagen directly into the injured tissue structures and monitor the structure itself and the ongoing remodeling processes. Combining such therapy with a well-planned rehabilitation training program allows for a quicker return to full fitness and reduces the risk of re-injury. This has been demonstrated through clinical examples illustrating the effectiveness of this training and sports therapy synergy in practice.
Collagen injections in otorhinolaryngology
Authors: Myszel Karol
Published: February 2025

Collagen is a natural material used in many areas od medicine. New applications of collagen in various medical specialties are more and more common. Use of collagen in otorhinolaryngology is a common practice in some indications, in others is still a matter of experiments.

Collagen is used in otorhinolaryngology for aesthetic effects. Patients after head and neck operations, mainly for oncological reasons (laryngectomy, neck lymphadenectomy), get collagen for scar smoothing and other corrective procedures. Trauma related scars (accidents, burns, radiotherapy) can be corrected with collagen. Skin defects of the nose after tumor excisions, like basal cell carcinoma, can be filled with collagen, to improve the aesthetic effect and patient`s quality of life. Similarly, collagen may be used to fill in nasal septum defects, mainly after trauma or overuse of decongestive nasal drops.

Otolaryngologists and dental surgeons use collagen to fill tissue deficits and lift maxillary sinus bottom in cases of alveolar perforations penetrating maxillary sinuses. The procedure is very effective in closing the gaps and limiting the inflammation process, leading to faster recovery.

In patients suffering from dysphonia due to vocal folds damages (vocal abuse, radiotherapy, chronic inflammations, post intubation trauma) collagen is used to fill tissue defects. The volume of the tissue increases which improves phonation and leads to better voice quality.

Some experimental collagen applications are still subjects of research. Collagen used to build a scaffolding for regenerating a respiratory ciliary epithelium, sealing the upper wall of tympanic cavity or treatment of trigeminal or facial neuralgia, are the examples.
Vaginal carbon dioxide laser therapy and tropocollagen injections – combination therapy of the genitourinary syndrome of menopause
Authors: Woźniak Andrzej
Published: February 2025

The genitourinary syndrome of menopause (GSM) affects 50–70% of postmenopausal women, necessitating effective treatments. Declining estrogen levels during menopause lead to significant changes in the genitourinary system, including vaginal atrophy.

Vaginal carbon dioxide laser (CO2) laser therapy involves the application of laser energy to the vaginal mucosa, creating controlled micro-injuries. This stimulates the production of new collagen and elastin fibers. The therapy results in the thickening and tightening of the vaginal epithelium, restoring its elasticity and moisture, consequently treating symptoms of GSM. Patients typically undergo a series of treatments, spaced several weeks apart, to achieve optimal results. The benefits include improved vaginal health, enhanced sexual function, and a reduction in urinary incontinence symptoms.

Vaginal collagen injections are a complementary treatment that involves injecting collagen directly into the vaginal tissue. This minimally invasive procedure aims to provide immediate support and structure to the vaginal walls. Collagen is a vital protein that contributes to the strength and elasticity of connective tissues. By injecting collagen, the treatment can enhance vaginal tightness, improve moisture levels, and provide relief from symptoms of GSM. The procedure is usually quick, with minimal downtime, allowing patients to resume their daily activities shortly after treatment.

Combining vaginal CO2 laser therapy with collagen injections offers a synergistic approach, enhancing the overall effectiveness of treatment. While the CO2 laser stimulates long-term collagen production and tissue remodeling, the collagen injections provide immediate structural support and symptom relief. This combination can significantly improve the quality of life for women suffering from GSM and related conditions.

Goitre, an enlarged thyroid gland, is a major health issue in tropical countries, primarily linked to Iodine deficiency. However, clinical, environmental, and genetic factors also contribute to the disease. This study explores the relationship between clinical and environmental factors influencing goitre occurrence in five districts of Sri Lanka: Anuradhapura, Colombo, Kurunegala, Nuwara Eliya, and Rathnapura, covering different climatic zones. The data consists of a hospital-based preliminary study conducted from 2012 to 2014, which involved 994 goitre patients from five base hospitals in Sri Lanka. A structured questionnaire survey recorded clinical examinations and investigation findings. Additionally, 562 water samples for Iodine and 147 samples for Selenium were collected from water sources used for drinking and cooking. The study included patients with a mean age of 43 years, predominantly females (98%), and 36% had a family history of goitre. Grades 3 and 4 were prevalent among the six goitre grades. All climatic zones showed an increasing trend of goitre grade with age. Notably, patients in the wet zone had higher goitre grades at younger ages compared to the other zones. Hierarchical cluster analysis based on environmental factors (Iodine and Selenium concentrations), clinical factors (thyroxine, triiodothyronine, and thyroid-stimulating hormone) and demographic factors identified seven clusters, categorizing patients based on dominant features. The most prominent cluster consisted of patients from Nuwara Eliya district, displaying a significant negative correlation between Iodine and Selenium levels with thyroxine. These clusters challenge the traditional methods of diagnosing endemic Goitre based solely on district and zone. The study provides valuable baseline data for effective planning and intervention strategies to prevent and treat goitre.
Conflict Resolution Strategies in Resolving Interpersonal Conflicts in Cameroon’s Public Corporations: The Case of the Cameroon General Certificate (GCE) Board
Authors: Newuawen Vubo Nelly
Published: February 2025

This study examines interpersonal conflict resolution strategies in public corporations, focusing on the Cameroon General Certificate of Education (GCE) Board. Public corporations are crucial for economic development but interpersonal conflicts among employees can hinder their effectiveness and performance. The strategies under study are collaboration, compromise, avoidance, accommodation, and competition. Through a mixed-methods approach, involving a survey using a questionnaire complemented with interviews, data was collected from managerial and non-managerial employees on conflict resolution strategies employed. The findings point to collaborative and compromise-based strategies that underlie improved productivity and job satisfaction as well as avoidance and competitive strategies that tend to exacerbate workplace tensions. The results provide insights for policymakers and corporate leaders to develop sustainable strategies for conflict management, thereby enhancing organizational resilience and service delivery.

Risk factors influencing informal contractors’ operations in the construction industry in selected local municipalities of the Free State Province, South Africa
Authors:   , Motlhale Kelehile Joseph
Published: February 2025

Operations by informal contractors in the construction industry plays an indispensable role in
informal economy of South Africa. However, several risk factors have continued to influence
the successful operations of informal contractor in the construction industry of South Africa.
This study therefore assesses the risk factors that influence informal contractors’ operations in
the construction industry. A comprehensive literature backed by different but related theories
such asthe dualists, the structuralists, and the voluntariststheories were sought to ascertain the
risk factors that impede industry’s operations throughout the project life cycle. A convergence
of mixed methods approach was employed to gather concurrent data through several multiple
sources. A 5 Likert-scale questionnaire and interview schedule were distributed to 304
informal contractors to gather primary data. To ensure enough triangulation data process, 18
informal contractors divided into 3 groups of 6 participants per group participated in focus
group discussions (FGDs) from 8 local municipalities (LMs). Qualitative and quantitative data
were analysed through SPSS statistical software aided by descriptive and inferential tools
supported by ANOVA to test formulated hypotheses. Qualitative data on the other hand, was
analysed using the thematic approach. Themes and sub-themes were derived from the
participants’ responses for meaningful inferences. The study revealed several risk factors such
as project design, financial, material, decision making, physical and environmental risks
among others that influence informal contractors’ operations in the construction industry. It
was established that though majority of informal contractors attained minimum educational
qualifications, yet they lack the requisite risk management knowledge within the construction
industry. Risk factors such as project design, financial, materials and decision-making
processes within the construction industry. Based on the study outcomes, it was concluded that
informal contractors should reduce the impact of all forms of risk factors within the
construction industry. To ensure maximum reduction of risk factors in the industry, this study
suggests an integrated risk factor identification framework (IRFIF) to be applied by informal
contractors during project operations. In general, the use of the IRFIF framework provides
beneficial for informal contractors across the informal economy. The IRFIF serves as a
strategic tool that is suggested to assist informal contractors to conduct an early identification
of the risk factors during operations to mitigate the occurrence of possible risk factors in the
industry.

Comparative Study of Feature Engineering Techniques for Predictive Data Analytics
Authors: Santoso Lukman , Priyadi
Published: February 2025

In the rapidly evolving era of big data, predictive analytics has become a crucial approach in supporting data-driven decision-making across various sectors such as finance, healthcare, and marketing. However, the effectiveness of predictive models is highly dependent on the quality of features utilized in model training. This study aims to evaluate and compare various feature engineering techniques to enhance the accuracy of predictive models based on Random Forest (RF) and Extreme Gradient Boosting (XGBoost) algorithms. The research employs a quantitative experimental approach by applying different feature engineering techniques, including SHAP-based feature importance, Principal Component Analysis (PCA), and categorical variable encoding. The evaluation results indicate that the implementation of SHAP-based feature importance yields the best outcomes, with a Mean Squared Error (MSE) of 0.150 and a Root Mean Squared Error (RMSE) of 0.387 in the XGBoost model. These values outperform those without feature engineering, which recorded an MSE of 0.230 and an RMSE of 0.479. The combination of PCA and encoding techniques also shows a significant performance improvement with an MSE of 0.160 and an RMSE of 0.400. The XGBoost algorithm consistently demonstrates superior performance compared to RF across various testing scenarios. The contribution of this study lies in its recommendation of appropriate feature engineering techniques to improve the predictive quality of Machine Learning (ML)  models. This research provides insights for researchers and practitioners in developing more effective feature engineering strategies and opens opportunities for exploring advanced techniques in more complex data domains.

Abstract. Loss of soil organic matter (SOM) from arable land poses a serious threat to soil fertility and crop yields, and it thwarts efforts to conserve soils as carbon sinks to mitigate global warming. Wind erosion can be a major factor in the redistribution of soil fines including SOM, but assessments of its impact have typically been limited by short observation periods of a few years at most. Longer time frames, extending back to the mid-20th century, may however be probed using the concentrations of radionuclides that were globally distributed by nuclear weapon tests conducted during the 1950s and early 1960s. The basic concept is that differences in fallout radionuclide (FRN) activities between undisturbed and arable soils can be used to infer soil particle redistribution. In the present work, we have measured activities of 137Cs and 239+240Pu in soils from three agricultural regions of the plains of the South African Highveld. The three regions represent distinct agroecosystems, and within each region the temporal length of cultivation varies from 0 (i.e. native grassland) to almost 100 years. Wind erosion has previously been shown to play a dominant role in soil particle loss from agricultural sites in the Highveld, and the level plots we investigate here did not show any evidence of fluvial erosion. Hence, we interpret the fate of soil fines, including SOM, to be governed by wind erosion. For the cultivated soils, radionuclide activities are found to be less than in adjacent native grassland, and the magnitude of the reduction is strongly correlated with the duration of cultivation. Specifically, the original inventories of both 137Cs and 239+240Pu are approximately halved after ∼20–40 years of cropping. The initial rate loss relative to the undisturbed soils is, however, considerably higher, with ∼6%yr-1 recorded during the first year after native grassland is converted to arable land. We correlate our radionuclide data with previously published SOM contents from the same sampled material and find that the radionuclides are an excellent indicator of SOM decline at the sites we investigate. We conclude that wind erosion can exert a dominant control on SOM loss in arable land of South Africa.

Abstract. Ammonia (NH3) is an abundant alkaline gas in the atmosphere and a key precursor in the formation of particulate matter. While emissions of other aerosol precursors such as SO2 and NOx have decreased significantly, global NH3 emissions are stable or increasing, and this trend is projected to continue. This study investigates the impact of NH3 emission changes on size-resolved aerosol composition and acidity using the atmospheric chemistry-climate model EMAC. Three NH3 emission schemes are analyzed: two bottom-up inventories and one derived using an updated top-down method. The results reveal that sulphate-nitrate-ammonium aerosols in two fine mode size ranges (0–1 µm and 1–2.5 µm) show the greatest sensitivity to NH3 emission changes. Regional responses vary depending on the local chemical environment of secondary inorganic aerosols. In 'NH3-rich' regions (e.g. East Asia and Europe), the abundance of NH3 partially offsets the effects of reduced NH3 emissions when NOx and SO2 are available, especially for aerosols in the 1–2.5 µm range. This highlights the importance of coordinated control strategies for NH3, NOx and SO2 emissions. Further, we find that NH3 has a buffering effect in densely populated areas, maintaining aerosol acidity at moderate levels and mitigating drastic pH shifts. The study emphasizes that pH changes are closely related to NH3 emission variations, with the highest sensitivity observed in the fine mode size ranges. These results highlight the critical role of NH3 in shaping aerosol acidity and argue for size-specific approaches to managing particulate matter.
