Authors: Klarić Eva , Špiljak Bruno , Šimunović Luka , Soče Majana , Grego Timor , Ivanišević Ana
Published: August 2024

Radiotherapy plays a key role in the treatment of the early and advanced stages of head and neck cancer. To date, there is still no consensus on the effects of radiotherapy on the mechanical properties of fluoride-releasing restorative materials which can be used in patients undergoing radiotherapy with increased incidence of caries. The fluoride-releasing materials Equia Forte HT and Cention N were compared to the resin-based materials Tetric EvoCeram and Tetric Power Fill. Standard irradiation was performed with a linear accelerator. Vickers microhardness, mass, surface roughness and color were measured before and after irradiation. Cention N and Tetric PowerFill showed stability in the mass, while the surface roughness did not change in any of the examined groups. Resistance to microhardness change was shown by Cention N, Tetric PowerFill and Tetric EvoCeram, and the color change was significant in all groups (p < 0.05). It should be remembered that patients receiving head and neck radiation therapy may experience adverse effects from the treatment, including changes in the mechanical properties of the restorative materials. The obtained results suggest that Cention N can be used as a material in patients undergoing head and neck radiotherapy due to the mechanical stability and depo effect of fluoride release.

Published: August 2024

This study explores the impact of social media platforms on enhancing social responsibility, employing a rigorous research framework based on the Uses and Gratifications Theory. We developed and tested a model to investigate how motivations for using social media influence social responsibility. A quantitative methodology was utilized, analyzing data from a sample of 520 participants using SmartPLS 4. The findings reveal various social media motivations—specifically information seeking, information sharing, self-status, social interaction, entertainment, being fashionable, and relaxation—significantly and positively impact social responsibility. The results underscore the constructive role of social media motivations in fostering social responsibility. They also suggest that further investigations into additional dimensions could provide deeper insights into how digital media might be leveraged to benefit society more broadly and enhance the concept of social responsibility. This study contributes to the expanding discourse on digital media’s potential to effect positive societal change.
Impacts of Generative Artificial Intelligence in Higher Education: Research Trends and Students’ Perceptions
Authors: Saúde Sandra , Barros João Paulo , Almeida Inês
Published: August 2024

In this paper, the effects of the rapid advancement of generative artificial intelligence (Gen AI) in higher education (HE) are discussed. A mixed exploratory research approach was employed to understand these impacts, combining analysis of current research trends and students’ perceptions of the effects of Gen AI tools in academia. Through bibliometric analysis and systematic literature review, 64 publications (indexed in the SCOPUS and Web of Science databases) were examined, highlighting Gen AI’s disruptive effect on the pedagogical aspects of HE. The impacts identified by the literature were compared with the perceptions held by computer science students of two different HE institutions (HEIs) on the topic. An exploratory study was developed based on the application of a questionnaire to a group of 112 students. The results suggest that while Gen AI can enhance academic work and learning feedback, it requires appropriate pedagogical support to foster critical, ethical, and digital literacy competencies. Students demonstrate awareness of both the risks and benefits associated with Gen AI in academic settings. The research concludes that failing to recognize and effectively use Gen AI in HE impedes educational progress and the adequate preparation of citizens and workers to think and act in an AI-mediated world.
The Emission-Reduction Effect of Green Demand Preference in Carbon Market and Macro-Environmental Policy: A DSGE Approach
Authors: Ding Xuyi , Ma Guangcheng , Cao Jianhua
Published: August 2024

Along with the new stage of prevention and control of the COVID-19 pandemic and the vision and goals of combatting climate change, the challenges of the transition to a green economy have become more severe. The need for green recovery of the economy, stability and security of energy production and consumption, and the coordination of low-carbon transformation and socio-economic development has become increasingly urgent. This paper proposes a new theoretical framework to study the effect of carbon emission reduction on the mutual application of the carbon market, fiscal policy and monetary policy under the non-homothetic preference of energy product consumption. By constructing an environmental dynamic stochastic general equilibrium (E-DSGE) model with residents’ non-homothetic preferences, this paper finds that coordinating the carbon market and macroeconomic policies can achieve economic and environmental goals. However, the transmission paths for each are different. The carbon market influences producers’ abatement efforts and costs through carbon prices. Monetary policy controls carbon emissions by adjusting interest rates, while fiscal policy controls carbon emissions by adjusting total social demand. Improving non-homothetic preferences will amplify business cycle fluctuations caused by exogenous shocks, thus assuming the role of a “financial accelerator”. Further research shows that non-homothetic preferences influence the heterogeneity of different policy mixes. Finally, this paper discovers that the welfare effects, the relative size and difference of long-term and short-term effects resulting from the different policy mixes, also depend on the level of non-homothetic preferences. The intertemporal substitution mechanism due to the improvement of non-homothetic preferences endows low-carbon production with “option” characteristics. Our study reveals the role of non-homothetic preferences on the effectiveness of policy implementation. It highlights the importance of matching monetary and fiscal policies with the carbon market based on the consumption and production side. It provides ideas for policy practice to achieve the goal of “dual carbon” and promoting coordinated socio-economic development.
Supporting Sustainable Development Goals through Regulation and Maintenance Ecosystem Services
Authors: Falasca Federico , Marucci Alessandro
Published: August 2024

Sustainable development goals (SDGs) have a huge impact on global policies. Contextually, the concept of ecosystem services (ESs) naturally relies on the importance of integrating human activities into a framework in which ecosystems play a fundamental role in supporting upcoming societies. Introducing ESs in the process of SDG evaluation can be useful to facilitate their achievement through national and local planning policies. Nevertheless, this aspect is still poorly addressed. In the present study, an in-depth analysis has been conducted, to associate regulation and maintenance ecosystem services (ReMESs) with the SDGs set by the 2030 Agenda. Based on the available scientific literature, ReMESs have been linked to the SDGs and SDG targets. Specific attention has been paid to deepening linkages with the SDG targets that explicitly address the introduction of ecosystem and biodiversity values into national and local planning. Finally, SDG evaluation has been further investigated, linking the SDG targets to the statistical measures proposed by the Inter-agency and Expert Group on SDGs (UN-IAEG-SDGs). This last step focused on the Italian context, according to the indicators provided by the National Institute of Statistics. The results show that ReMESs are linked to 8 out of 17 SDGs (47%). Connections decrease when considering the SDG targets (20%) and the national statistical measures (18%). It also emerges that some targets, although being connected to ReMESs, do not have the right indicators to be quantified. Ecosystem services prove to be a valid element through which modern sustainable development goals can be accomplished. This study, which highlights several gaps to be filled, wants to offer valuable help in evaluating SDGs and their implementation through ReMESs.

Authors: Kanabar Pinkky , Wu Ying , Nandwani Dilip
Published: August 2024

Fulvic acid (FA) is an eco-friendly solution for reducing the reliance on agrochemicals and enhancing crop quality. The study aimed to investigate the impact of soil and foliar application of FA on the phytochemical content and antioxidant properties of organically grown bell peppers at both the green and red stages. Bell pepper cv. Revolution was grown under open-field conditions at the certified organic farm at Tennessee State University, Nashville, with nine treatments and three replications. FA was applied as a soil drench and foliar spray at four different rates (0, 2.3, 5.5, 7.8, 10.9 mL L−1). The fruits were harvested 55 days (green stage) and 86 days after transplantation (red stage). The study showed significant differences (p ≤ 0.05) between the treatment and maturation stage. The foliar treatment of 7.8 mL L−1 resulted in the highest phenolic content in green bell peppers. The highest total flavonoid content in red bell peppers was achieved with a soil treatment of 7.8 mL L−1. Additionally, the highest level of vitamin C in red bell peppers occurred with a soil concentration of 5.5 mL L−1. In conclusion, applying FA as a biostimulant can enhance the quality of organically grown bell peppers, offering promising opportunities for sustainable agricultural practices.
Outward Foreign Direct Investment and Supply Chain Concentration: Evidence from China
Authors: Jing Hao , Zhan Weiwei
Published: August 2024

The potential risks arising from excessive supply chain concentration have received more and more attention. In practice, high supply chain concentration hinders firms’ sustainable development, especially for firms in emerging markets. However, how to reduce supply chain concentration remains an underexplored problem. Outward foreign direct investment (OFDI) has been an important strategy for firms to reallocate and optimize their supply chain relationships. Thus, we tried to explore whether OFDI can serve as an effective method to reduce supply chain concentration by analyzing their relationship. Using the data of Chinese A-share listed firms from 2008 to 2022, this paper empirically examines the impact of OFDI on supply chain concentration through a two-way fixed-effects model. We find that OFDI significantly reduces supply chain concentration, and this conclusion still holds after using alternative measures of the independent variable and dependent variable, endogeneity treatment, the Heckman two-stage model test, controlling for provincial factors, and excluding special samples. Channel analysis reveals that OFDI reduces supply chain concentration mainly through increasing market share, enhancing innovation capacity, and improving reputation. Cross-sectional analysis shows that the negative effect of OFDI on supply chain concentration is more pronounced in state-owned firms, firms under high industry competition, and high-tech firms. Our findings have important implications for firms to build sustainable supply chain relationships and strengthen supply chain resilience, and for policymakers to guide OFDI reasonably. Future research could further explore the effect of firms’ investment decisions on supply chain configuration.
Effects of Carbon-Based Modified Materials on Soil Water and Fertilizer Retention and Pollution Control in Rice Root Zone
Authors: Huang Wei , Jia Yangwen , Niu Cunwen , Zhang Hexi , Wang Yongtao , Feng Cheng
Published: August 2024

To seek an appropriate stabilization and remediation scheme for cadmium (Cd) and arsenic (As) pollution in farmland, a typical polluted soil sample was selected from a mining area in Southwest China for a soil box simulation experiment. Biochar (BC), a modified type of biochar made from rice husk with different mass ratios of ferric chloride and rice husk, was set up (the mass ratio of ferric chloride to rice husk was 1:9 (defined as LFB), 3:7 (defined as MFB), and 5:5 (defined as HFB) and the control group (BL)) to explore the effects of soil water and fertilizer loss, the bioavailability of Cd and As, and the bioenrichment effects of plant organs during the growth period of rice. The results showed that the porous structure and large specific surface area of biochar effectively regulated soil aggregate composition and improved soil water holding capacity. Compared to the BL treatment, soil water storage under the four carbon-based material control modes increased from 8.98% to 14.52%. Biochar has a strong ion exchangeability and can absorb soil ammonium, nitrogen, and phosphoric acid groups, effectively inhibiting the loss of soil fertilizer. Biochar improves soil pH and reduces the specific gravity of exchangeable Cd. In addition, the oxygen-containing functional groups in biochar can react with metals in a complex manner. The diethylenetriaminepentaacetic acid (DTPA) concentrations of Cd in soils treated with BC, LFB, MFB, and HFB were 79.69%, 72.92%, 64.58%, and 69.27% lower, respectively, than those treated with BL. In contrast, the Fe3+ in ferric chloride combines with As after hydrolysis and oxidation to form amorphous ferric arsenate precipitates or insoluble secondary minerals. Therefore, the curing effect of the modified biochar on As was more potent than that of applied biochar alone. In conclusion, ferric chloride-modified biochar can effectively inhibit the effects of water and fertilizer loss in farmland soil and realize cross-medium long-term inhibition and control of combined Cd and As pollution.

Authors: Wierzbicka Wioletta , Farelnik Eliza
Published: August 2024

The objective of this study has been to diagnose the demographic situation of older people in municipalities that belong to the Polish National Cittaslow Network, and to assess their potential for developing a local silver economy. The study covered all 36 municipalities that compose the Polish National Cittaslow Network. The following research methods were employed: a critical review of the literature, analysis of secondary data, including strategic development planning documents, and quantitative methods, including a method of grouping objects on the basis of a synthetic variable. The study has demonstrated that nearly all Cittaslow municipalities experienced a decrease in population during the analyzed period, which coincided with a growing share of the non-working-age population. This attests to the ongoing process of population aging. A significant challenge that the analyzed municipalities faced was determined to be the growing demographic burden. Based on a synthetic indicator of the potential for silver economy development, the municipalities were divided into five classes: very high, high, medium, low, and very low potential. Interestingly, most of the municipalities are now distinguished as having medium, low, or very low potential for the development of the silver economy. The analysis presented in this article contributes to further research on factors and tools shaping a development policy that may influence the development of the silver economy in the Cittaslow municipalities of Poland and the world.
Cell Formation Problem with Alternative Routes and Machine Reliability: Review, Analysis, and Future Developments
Authors: Figueroa-Torrez Paulo , Durán Orlando , Sellitto Miguel
Published: August 2024

The Cell Formation Problem (CFP) is a widely studied issue that aims to group machines effectively based on criteria such as productivity, lower costs, and greater efficiency. In recent years, more characteristics were summarized relating to this problem. This paper provides a bibliographic examination of methodologies addressing the CFP in cellular manufacturing, focusing on novel approaches such as alternative routes and machine reliability. The articles were obtained from Scopus and Web of Science and filtered using the PRISMA methodology. Classification based on objective functions, constraints, and methodologies facilitated informative visualizations for analysis. Findings indicate a focus on capital utilization optimization, with cost reduction via intercellular moves minimization as the primary objective. Common constraints include limits on the number of machines per cell, restricting machines to a single cell and singular production routes per part. The genetic algorithm predominates as a non-exact solution approach, while the “ε-constraint” method is commonly used. This study offers insights into contemporary trends in solving the CFP with alternative routings and machine reliability, aiding researchers and professionals in the field to improve the quality of their investigations.

Published: August 2024

As a representative item of chemical carcinogen, MNNG is closely associated with the onset of gastric cancer (GC), where N6-methyladonosine (m6A) RNA methylation is recognized as a critical epigenetic event. In our previous study, we found that the m6A modification by methyltransferase METTL3 was up-regulated in MNNG-exposed malignant GES-1 cells (MC cells) compared to control cells in vitro, and long non-coding RNA SNHG7 as a downstream target of the METTL3. However, the functional role of METTL3 in mediating the SNHG7 axis in MNNG-induced GC remains unclear. In the present study, we continuously investigate the functional role of METTL3 in mediating the SNHG7 axis in MNNG-induced GC. RIP-PCR and m6A-IP-qPCR were used to examine the molecular mechanism underlying the METTL3/m6A/SNHG7 axis in MNNG-induced GC. A METTL3 knockout mice model was constructed and exposed by MNNG. Western blot analysis, IHC analysis, and RT-qPCR were used to measure the expression of METTL3, SNHG7, and EMT markers. In this study, we demonstrated that in MNNG-induced GC tumorigenesis, the m6A modification regulator METTL3 facilitates cellular EMT and biological functions through the m6A/SNHG7 axis using in vitro and in vivo models. In conclusion, our study provides novel insights into critical epigenetic molecular events vital to MNNG-induced gastric carcinogenesis. These findings suggest the potential therapeutic targets of METTL3 for GC treatment.
Receptor Tyrosine Kinase Signaling Involves Echinococcus–Host Intercommunication: A Potential Therapeutic Target in Hepatic Echinococcosis
Authors: Gao Haijun , Bianba Zhuoma , Mo Xiaojin , Hu Wei , Feng Zheng , Zhou Fangye , Zhang Ting
Published: August 2024

Echinococcosis, one of the most serious and life-threatening parasitic forms of zoonosis worldwide, is caused by the larvae of Echinococcus granulosus (E. granulosus) and Echinococcus multilocularis (E. multilocularis). Various drugs are being applied clinically to treat zoonosis; however, their therapeutic efficacy remains a great challenge, especially with albendazole as the preferred drug of choice. Receptor tyrosine kinase (RTK) signaling controls normal cellular proliferation, differentiation, and metabolism in humans and mammals, which are intermediate hosts of E. granulosus and E. multilocularis. Disruption of RTK signaling can cause various forms of carcinogenesis and exacerbate the progression of certain forms of parasitic disease. As a result, a significant number of studies on tyrosine kinase inhibitors (TKIs) have been conducted for the treatment of cancer and parasitic infection, with some TKIs already approved for clinical use for cancer. Notably, RTK signaling has been identified in the parasites E. granulosus and E. multilocularis; however, the mechanisms of RTK signaling response in Echinococcus–host intercommunication are not fully understood. Thus, understanding the RTK signaling response in Echinococcus–host intercommunication and the potential effect of RTK signaling is crucial for identifying new drug targets for echinococcosis. The present review illustrates that RTK signaling in the host is over-activated following infection by E. granulosus or E. multilocularis and can further facilitate the development of metacestodes in vitro. In addition, some TKIs exert strong parasitostatic effects on E. granulosus or E. multilocularis, both in vitro and/or in vivo, through downregulation of RTK signaling molecules. The summarized findings suggest that RTK signaling may be a promising drug target and that TKIs could be potential anti-Echinococcus drugs warranting further research.
TRIMming down Flavivirus Infections
Authors: Cannac Marion , Nisole Sébastien
Published: August 2024

Flaviviruses comprise a large number of arthropod-borne viruses, some of which are associated with life-threatening diseases. Flavivirus infections are rising worldwide, mainly due to the proliferation and geographical expansion of their vectors. The main human pathogens are mosquito-borne flaviviruses, including dengue virus, Zika virus, and West Nile virus, but tick-borne flaviviruses are also emerging. As with any viral infection, the body’s first line of defense against flavivirus infections is the innate immune defense, of which type I interferon is the armed wing. This cytokine exerts its antiviral activity by triggering the synthesis of hundreds of interferon-induced genes (ISGs), whose products can prevent infection. Among the ISGs that inhibit flavivirus replication, certain tripartite motif (TRIM) proteins have been identified. Although involved in other biological processes, TRIMs constitute a large family of antiviral proteins active on a wide range of viruses. Furthermore, whereas some TRIM proteins directly block viral replication, others are positive regulators of the IFN response. Therefore, viruses have developed strategies to evade or counteract TRIM proteins, and some even hijack certain TRIM proteins to their advantage. In this review, we summarize the current state of knowledge on the interactions between flaviviruses and TRIM proteins, covering both direct and indirect antiviral mechanisms.

Published: August 2024

Bovine tuberculosis is caused by Mycobacterium bovis, a member of the M. tuberculosis complex of mycobacterial species that cause tuberculosis in humans and animals. Diagnosis of bovine tuberculosis has relied on examinations of cell-mediated immune responses to M. bovis proteins using tuberculin skin testing and/or interferon gamma release assays. Even when using these methods, disease detection during the earliest phases of infection has been difficult, allowing a window for cattle-to-cattle transmission to occur within a herd. Alternative means of diagnosis could include methods to detect M. bovis or M. bovis DNA in bodily fluids such as nasal secretions, saliva, or blood. During the first 8 weeks after experimental aerosol infection of 18 calves, M. bovis DNA was detected in nasal swabs from a small number of calves 5, 6, and 8 weeks after infection and in samples of saliva at 1, 7, and 8 weeks after infection. However, at no time could culturable M. bovis be recovered from nasal swabs or saliva. M. bovis DNA was not found in blood samples collected weekly and examined by real-time PCR. Interferon gamma release assays demonstrated successful infection of all calves, while examination of humoral responses using a commercial ELISA identified a low number of infected animals at weeks 4–8 after infection. Examination of disease severity through gross lesion scoring did not correlate with shedding in nasal secretions or saliva, and calves with positive antibody ELISA results did not have more severe disease than other calves.

Published: August 2024

Este artículo visibiliza la problemática de los estudiantes con discapacidad en una zona rural de Cusco. Se determinan los desafíos de la inclusión educativa, considerando las barreras que afectan a esta población. La investigación original empleó una metodología cualitativa con un diseño de investigación-acción, aplicada a 27 familias y 5 docentes mediante una encuesta de escalas ordinales. Los resultados mostraron que la comunicación entre estudiantes e instituciones educativas era limitada, principalmente a través de teléfonos celulares convencionales, en un entorno con conectividad deficiente. Además, las familias vivían en condiciones de extrema pobreza, dedicándose a la agricultura, el comercio y trabajos eventuales, lo que hacía que la responsabilidad educativa recaiga mayoritariamente en las madres. Los docentes expresaron la necesidad de capacitación especializada y propusieron utilizar materiales impresos adecuados y adaptados a las necesidades de los estudiantes con discapacidad, como una forma de mitigar las barreras tecnológicas y económicas.

Published: August 2024

Gestionar el aprendizaje participativo, autónomo y permanente es muchas veces una labor extenuante que pocos están dispuestos a asumirla. Se tiene una fuerte convicción de que esta situación es producto de la limitada comunicación entre aquel que enseña y aquel que aprende. El objetivo de la investigación fue establecer la relación existente entre la retroalimentación y la motivación para el aprendizaje de las matemáticas en estudiantes de pregrado de una universidad pública de Lima. El estudio corresponde a un diseño transversal correlacional. La muestra estuvo conformada por 179 estudiantes, a quienes se les aplicaron dos cuestionarios, uno de retroalimentación (? = .94) y otro sobre motivación (? = .93). Los resultados evidenciaron una correspondencia significativa y directa entre la retroalimentación y la motivación para el aprendizaje de las matemáticas (r = .658; p = .000). Finalmente, se concluyó que cuando mejor se brinde la retroalimentación, mejor será la motivación para el aprendizaje de las matemáticas.

Published: August 2024

The Greater Bandung area grapples with various challenges, including spatial planning, waste management, water resources, critical land, and transportation, all of which are intricately linked to sustainability concerns, particularly affecting tourism. To address these issues, it is crucial to understand tourists' preferences for green promotion attributes in destinations. This study employs conjoint analysis to discern tourists' perceptions of various destination attributes. Findings reveal that Greater Bandung tourists prioritize environmentally friendly tourism activities as the most significant destination image attribute, while ecologically friendly transportation ranks as the least important. Additionally, when assessing destination advertising attributes, environmentally friendly visuals hold more importance than environmentally friendly messaging. Tourists prioritize sustainable product packaging, while they consider the destination's tourist product color to be less significant. These findings underscore the importance of clear communication, ecolabeling, and environmentally friendly practices in promoting sustainable tourism in the Greater Bandung area.

The focus of the present work is to develop and optimize an electrochemical laccase-based biosensor for the determination of 3,4-dihydroxyphenyl-alanine, also known as L-DOPA. The biosensor was assembled on a conventional glassy carbon electrode, the surface of which was covered with laccase enzyme retained under a thin Nafion™ membrane. The enzymes used for this purpose were isolated and purified from the white-rot basidiomycetes (Trametes sp.) Trametes pubescens and Trametes versicolor. Although biochemically similar, the two enzymes demonstrated some differences in their affinity not only using 3,4-dihydroxyphenyl-L-alanine as enzyme substrate, but also when catecholamines such as dopamine and L-epinephrine were used. A range of electrochemical techniques were used for the study, such as cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy. Experiments were performed using buffers with different pH and applying various substrate concentrations. Activity and sensitivity of the two alternative laccase – based biosensors were compared by means of chronoamperometry. The biosensor produced on the basis of Trametes pubescens laccase, operating in citrate buffer with pH 4 proved to be more suitable than the one based on laccase purified from Trametes versicolor for biosensing L-DOPA.

Introdução: O uso de drogas é considerado um problema de saúde pública. Quando se dá por gestantes, há um agravamento, causando danos à própria saúde e à de seus fetos.  Objetivo: Comparar o perfil socioeconômico das gestantes usuárias (expostas) e não usuárias (controle) de cocaína/crack e seus desfechos perinatais. Metodologia: Foi realizado um estudo epidemiológico observacional, do tipo transversal, composta por 120 díades mãe/recém-nascido, sendo 60 do grupo controle (não exposto) e 60 do grupo exposto (uso de drogas). Foram aplicados questionários as gestantes sobre o uso de drogas e medidas antropométricas dos recém-nascidos foram realizadas.  Resultados: 65% das mães expostas estavam desempregadas e das mães controle 35%; 3% das mães expostas recebiam 3-4 salários mínimos, 13% das mães controle apresentavam essa faixa de renda; 68% das mães realizaram até 3 consultas pré-natal, enquanto 41% das mães controle fizeram 7 consultas ou mais. Os filhos de mães expostas apresentaram menor estatura e perímetro cefálico quando comparados aos filhos das mães controle. Conclusão: Gestantes usuárias de drogas apresentaram um perfil de fragilidade socioeconômica e bebes com menor estatura e perímetro cefálico ao nascimento. Portanto, a exposição do feto à substancias ilícitas intra-útero gerou piores desfechos perinatais nos recém nascidos.
Determinants influencing online shopping behaviour among 18-30-year-olds in Gauteng, South Africa: an examination of pricing, quality, security, time and information availability

Published: August 2024

This study explores the determinants influencing online shopping behaviour among 18-30-year-olds in Gauteng, South Africa, focusing on key factors, such as pricing, quality, security, time, and information availability. Grounded in the Technology Acceptance Model (TAM) and Perceived Risk Theory, this research aims to provide a comprehensive understanding of how these factors impact consumer decisions and behaviours. A cross-sectional survey methodology was employed, targeting 1,043 respondents who have shopped online within the past six months in Gauteng. The findings reveal that all five factors significantly influence online shopping behaviour, with information availability and time efficiency showing the strongest correlations. The study also highlights that despite the high perceived convenience and satisfaction with online shopping, security concerns remain a barrier to adoption. The study suggests that online retailers should enhance their security measures, provide detailed product information, and streamline their online processes to improve customer experience and trust.  The study developed a conceptual framework to identify the factors influencing online shopping behaviour among 18-30-year-olds in Gauteng. This model includes six constructs: pricing, quality, security, time, information availability, and online shopping behaviour. This framework can be applied in future research. Limitations of the study include its narrow geographic and demographic focus on the 18-30-year-old population in Gauteng, South Africa, which restrict the generalisability of findings to other age groups or regions.  Additionally, the cross-sectional design provides a snapshot rather than longitudinal insights into how online shopping behaviours evolve over time.

This research was conducted on the topic of the Influence of Regional Transfer and Village Fund Expenditure as government spending instruments in the state budget on Development Inequality in Indonesia. The study utilized Regional Transfer and Village Fund Expenditure (TKDD) data as the independent variable. Meanwhile, the dependent variables were the Regional Disparity Index (Williamson Index) and the Gini Ratio as representations of regional inequality in Indonesia. The data used consisted of panel data, including TKDD expenditure, per capita GRDP, and the population of each province in Indonesia from 2017 to 2021. The research employed a quantitative method using panel data regression analysis (Pooled data). Based on the LM Test results, the Random Effect Model was found to be better than the Common Effect Model for estimating the regression model between TKDD and the Williamson Index (IW) variables. Meanwhile, the best model for estimating the regression model between TKDD and the Gini Index (IG) variables was the Fixed Effect Model after conducting the Chow Test and Hausman Test. Regression testing results indicated that the TKDD variable had a negative and non-significant relationship with the IW variable (development inequality). This is evident from the coefficient value of -0.101798 and a probability value of 0.6012 (greater than 0.05), meaning it is not significant. Similarly, the regression results between the TKDD variable and the IG variable showed a coefficient value of -16477.71 and a probability value of 0.1410 (greater than 0.05), indicating non-significance.
