SOCIAL INTERACTION, INFORMATION SHARING, AND BRAND TRUST IN OPTIMIZING PURCHASE INTENTION BASED ON THE THEORY OF PLANNED BEHAVIOUR
Authors: Rahma Atika
Published: January 2025

Social interaction is the most crucial variable in this research. Previous studies indicate that research gaps need to be investigated further. These findings provide important insights for companies to develop effective marketing strategies that leverage the power of social interactions and information sharing to build brand trust and increase purchase intention. This research chose Bandung, Surabaya, Semarang, Yogyakarta, Lampung and Medan as the population because they are the cities that use the most cosmetic products. The author uses nonprobability sampling with a purposive sampling technique. Researchers took a sample of 145 respondents from generations Y and Z who are active cosmetic users. This research uses a quantitative approach with data analysis using SPSS 29 and Amos Graphic 26 software. This research is new to previous research that added the brand trust variable. This research found that brand trust does not influence purchase intention. For consumers who feel that cosmetic products do not provide commensurate benefits with high prices, brand trust tends not to influence purchase intentions. JEL: M31, M21, L84.Keywords: social interaction, information sharing, brand trust, brand equity, purchase intention, theory of planned behaviour.

Authors: Kerackian Taline , Wespiser Clément , Daniel Matthieu , Pasquinet Eric , Romero Eugénie
Published: January 2025

Access to the nitro functional group is a very common and longstanding transformation of interest in many fields of chemistry. However, the robustness and specificity of this transformation can remain challenging, particularly in the case of heteroarene nitration. From this observation, a large investigation was initiated to screen nitration conditions on various arenes and heteroarenes. The systematical and diverse study of both nitrating agents and activating reagents was conducted using high-throughput experimentation, to afford high quantity and high quality data generation. General trends have been identified and correlated to the electronic property of the heteroarene, notably the difficult nitration of electron-poor heteroarenes was highlighted. Original combinations of reagents were found to perform well in nitration reactions. The obtained data were also used to design a predictive tool relying on machine learning in order to provide the best nitration reaction conditions depending on the targeted substrate. The limited predictive efficiency obtained pointed out the importance of the diversification and the chemically relevant encoding of the data set.
Efficient Analysis of Small-Angle Scattering Curves for Large Biomolecular Assemblies Using Monte Carlo Methods
Authors: Chiang Huat Thart , Zhang Zhiyin , Vaddi Kiran , Tezcan Akif , Pozzo Lilo
Published: January 2025

Structure elicitation from small angle scattering (i.e. SAXS, SANS) curves of large biomolecular assemblies is notoriously challenging. This is because the simulation of high-resolution features in the structure of large macromolecular assemblies, such as de-novo protein assemblies, is computationally demanding when it needs to cover a broad range of length scales. Conventional methods such as the numerical approximation to the Debye equation or the use of spherical harmonics do not scale well as the size of the assembly increases, which limits their application to small structures (e.g. individual proteins). This work explores the effectiveness of a Monte Carlo method to simulate and fit scattering curves for large biomolecular assemblies spanning over ranges covering atomic and molecular detail, as well as large scale (100’s of nm) features. Due to its excellent speed and scalability, it can be combined with a fitting algorithm to extract structural features from experimental small-angle scattering curves in biomolecular assemblies that are otherwise intractable for interpretation. This work first demonstrates the effectiveness of the tool using experimental small angle X-ray scattering (SAXS) data from tile-like proteins that assemble into 1D tube-like macromolecular structures. The diameter distribution of tubes is extracted from SAXS fits, and this quantitatively compared with distributions from electron microscopy. SAXS data is also obtained from 2D sheet-like protein assemblies and the proposed method is used to quantify structural features such as the separation distance between protein building blocks and the flexing of the sheet. An open-source implementation of the methodology is provided for use in a broad range of biological systems involving multi-scale scattering analysis.

The origin of the bioaccumulative neurotoxin methylmercury (MeHg) in the ocean remains elusive. The current paradigm suggests that microbial methylation of inorganic Hg within the oceanic water column produces monomethylmercury (MMHg) and potentially dimethylmercury (DMHg). Reaction rates and main drivers governing MeHg levels (sum of MMHg and DMHg) are poorly constrained. We conducted ambient Hg species measurements and enriched isotopic tracer experiments in waters of two contrasting marine environments, the oligotrophic Mediterranean Sea (MED) and the mesotrophic Atlantic Ocean (ATL). Maximum subsurface MeHg levels were ~2 times higher in the MED compared to the ATL, essentially driven by higher DMHg concentrations (0.45 ± 0.06 vs 0.16 ± 0.02 pM). Methylation was only detectable in unfiltered subsurface waters and presumably biotically driven. The highest methylation rate (MMHg to DMHg) was observed in subsurface MED waters while reduction and demethylation rates were highest in surface waters of both environments. Experimental reaction rates and the potential microbial activity (based on 16S rDNA) aligned with ambient Hg species distributions. Assuming high DMHg stability and applying our fast experimental DMHg formation rates, a newly developed 1D water column model (MED) successfully reproduced MeHg species distribution, suggesting DMHg plays a key role in the global marine Hg cycle.

Published: January 2025

When producing plant-protein-based meat analogues via high moisture extrusion (HME), the structure of extrudates is determined by complex interactions between ingredient composition and processing conditions. To facilitate consumers in their transition towards a diet higher in plant-based proteins, the food industry aims to closely mimic the structure of meat of animal origin. Currently, insights into the structuring process are gained, for example, by imaging samples using MRI or confocal microscopy. Existing software for analysing these images, however, often lacks the ability to quantitively analyse structure and anisotropy. Here, we present a new image processing method, named Rotated Fourier Transform (RFT), that enables the quantification of anisotropic structures of extrudates from multimodal images acquired at different length scales. RFT can provide a single measure of structural anisotropy, namely the weighted order parameter (WOP), for either the entire image or subregions thereof. RFT utilises Fourier transforms to obtain the dominant angles representing the structural orientation detected within the image. For each dominant angle, we further calculate an amplitude relative to the background within each sub-image. These amplitudes depend on the signal-to-noise levels of the corresponding angular features, which enables reducing the influence of insignificant features on the WOP. Here, we used RFT to quantify anisotropy in images of soy protein concentrate HME samples. We identified both anisotropic and isotropic regions and further showed that the relative spatial extent of the anisotropic region, perpendicular to the flow direction, increases along the cooling die. While applied in this paper to the specific case of soy HME samples, RFT is a generic method applicable to any image displaying anisotropic features. Thus, RFT is a powerful and robust tool for comprehensive quantification of food structures and beyond.

Authors: Pichugin Sergii
Published: January 2025

The buildings and structures reliability and safety largely depend on a proper understanding of the nature and quantitative description and rationing of loads on building structures, including crane loads. Most of the parameters of the crane load codes have a probabilistic nature and require the use of statistical methods to substantiate them. These methods are constantly changing and evolving together with the regular revision of building design codes. Analysis of domestic codes' evolution of crane load together with their statistical substantiation is an urgent task, which is this article's purpose. Since the late 1930s, leading construction research institutes and universities have conducted research on crane loads, which results have been consistently incorporated into design codes. Giving an overall assessment of Ukrainian crane loads standards, it should be emphasized that they are compiled on a modern methodological basis, close to European standards Eurocode, based on representative statistics, more differentiated, and have a scientific probabilistic nature.

Authors: Mykhailovska Olena , Soloviev Veniamin
Published: January 2025

Experimental studies of changes in rock properties depending on the pressure in the well and in the massif of the plastic layer at different distances from the well over time were carried out. The function demonstrates the power dependence of the pressure ratio at the moment of time on the geostatic pressure. After sealing the well, the pressure in the massif of the plastic formation increases in the near-well zone and decreases in the peripheral zone. Over time, the pressure in the massif of the plastic layer is equalized over the entire area of the layer. Pressure changes in a plastic rock have an impulse character. Thermal (residual) stresses affect the destruction of rocks during drilling with an increase in the depth of the well
Corporate Culture and Its Influence on Accounting Practices: Lessons from KPMG and PwC in South Africa
Authors: Ma-Nlep Massoda
Published: January 2025

In essence, an accounting firm is a company that helps its clients make sure their financial transactions are accurate and legal. The particularity of South Africa (SA) with the audit profession resides in the expectation that, in addition to the auditor’s duty to express an opinion on a client’s financial statements, the external auditor is also expected to highlight ‘reportable irregularities’ to the attention of an independent regulator: the Independent Regulatory Board for Auditors (IRBA) (Warren Maroun, 2012).

The adoption of the culture of wealth creation at any cost has induced these 2 accountancy firms in SA to behave like any other business in the pursuit of higher profits. Like any other corporations, KPMG and PwC had developed a recurring trend of protecting their gains at any cost, as they were willing to increase their profits through indulgence in price fixing, tax avoidance/evasion, bribery, corruption, money laundering and practices that show little regard for social norms and even laws (Pre
Numerical Simulation for Obtaining Advanced Engineering Applications Through an Important Fluid Problem
Authors: Tedjani Ali H. , Khader Mohamed M.
Published: January 2025

The current work examines the transfer of heat/mass in a thin liquid film (TLF) with high viscosity on a surface that is continuously stretching. Through thorough mathematical modeling, a system of PDEs is established. The application of appropriate similarity transformations results in the formulation of a set of nonlinear ODEs from the original system of PDEs. Here, we introduce a reliable numerical technique to analyze the solution characteristics of the proposed problem. This technique depends on applying shifted Chebyshev polynomials of the sixth-order (SCP6s). Initially, we obtain an approximate expression for the derivatives by using SCP6s. In this study, we employ a spectral collocation procedure, leveraging the unique characteristics ofSCP6s. This approach enables the transformation of the presented problem into a set of nonlinear algebraic equations. Notably, we emphasize the presentation of specific theorems that pertain to examining the convergence of the proposed approximation technique. Our present findings exhibit a remarkable concurrence with the investigations that have been previously reported.
Non-Perturbative Approach in Scrutinizing Nonlinear Time-Delay of Van der Pol-Duffing Oscillator
Authors: Alanazy Asma , Moatimid Galal , Amer Tarek , Galal Abdallah
Published: January 2025

The time-delayed (TD) of velocity and position are employed throughout this investigation to lessen the nonlinear vibration of an exciting Van der Pol-Duffing oscillator (VdPD). The issue encompasses multiple real-world elements such as feedback lags, signal transmission delays, and delayed responses in mechanical, electrical, or biological systems. Actually, examining this oscillator facilitates the investigation of complex dynamics, including chaos, bifurcations, and stability alterations, rendering it essential for disciplines like control theory, engineering, and neuroscience. The current oscillator is analyzed using the NPA. This methodology is based mainly on the He’s frequency formula (HFF). Simply, this approach transforms the nonlinear ordinary differential equation (ODE) into a linear one. Accordingly, the stability standards are constructed, depicted, and sketched. Contrasting the analytical solution (AS) with the associated numerical data, which reveals high nonlinearity, the numerical estimation is validated via the Mathematica Software (MS). In contrast to other traditional perturbation methods, the NPA exhibits high convenience, accessibility, and great precision in analyzing the behavior of strong nonlinear oscillators. Subsequently, this technique enables the analysis of issues related to other oscillators in dynamical systems. It is an effective and promising method for addressing similar dynamic system challenges, providing a qualitative assessment of theoretical outcomes. The study describes time histories of solutions for different natural frequencies and TD parameters and discusses the main findings based on displayed curves. It also examines how various regulatory limits impact the vibrating system. The performance is applicable in engineering and other domains owing to its flexibility in various nonlinear systems. Consequently, the NPA can be considered significant, effective, and intriguing, with potential for use in more categories within the domain of coupled dynamical systems.

The Hitchcock-Koopmans transportation problem is a well-known and fundamental optimization problem which focuses on minimization of the objective function which is basically the transportation cost from multiple sources to multiple destinations. In this article, we present some novel results on the spectral properties of structured matrices appearing in Hitchcock-Koopmanstransportation problems. The results on the computation of singular values are presented with usage of tools from linear algebra and matrix analysis. The new results are derived on interconnection between structured singular values of pseudo-inverse and D-stable matrices of Hitchcock-Koopmans transportation models. The numerical experimentation shows the behavior of singular values. The Matlab EigTool is used for the computation of pseudo-spectrum of pseudo-inverse matrix corresponding to the transportation model.

Propuesta teórica para la Intervención Biopsicosocial con duplas psicosociales en el contexto escolar
Authors: Astorga Rubio Daniela Anaís
Published: January 2025

La visualización del aumento de la violencia escolar y de las problemáticas de salud mental en niños, niñas y adolescentes, como desafíos sociales actuales del sistema educativo, ha generado la necesidad de incorporar estrategias integrales en los contextos escolares. Para atender estas necesidades, el Ministerio de Educación (MINEDUC, 2024) desarrolló la Política Nacional de Convivencia Escolar (2024-2030), que busca promover comunidades escolares inclusivas y reflexivas, centradas principalmente en el desarrollo de relaciones democráticas.

Published: January 2025

Health and nutrition form crucial elements of human capital development, where their relationship with human resource development is mutually reinforcing and cyclical. Nutrition, integral to both health and developmental outcomes, receives significant emphasis in the formation of human capital across developed nations today. This process commences during childhood, underscoring its foundational role in modern societal advancement. The physical health of an individual during the early stages of life plays a pivotal role in determining the quality of human capital. Proper nutrition is essential for sustaining and enhancing health, particularly in these formative years. During childhood, nutrition serves as the primary source of essential nutrients, including macronutrients and micronutrients, which are critical for growth and development. Moreover, proper nutrition during early life stages can reduce the risk of non-communicable diseases later in life, laying the foundation for healthier and more productive individuals as they grow. This underscores the importance of ensuring that children receive the necessary nutrients from a young age to promote their overall well-being and long-term human capital development. 213 respondents were considered in the study as a sample size. Mean and T-test was applied in the study to find the outcome.

Authors: Mohit Kumar  , Hooda Neelam
Published: January 2025

This paper provides a postcolonial reading of Shashi Tharoor’s The Great Indian Novel, exploring the complex relationship between myth and nationalism within the context of Indian history and politics. Tharoor reinterprets the Mahabharata as an allegorical narrative that mirrors the political struggles and contradictions of postcolonial India. Through a satirical and intertextual narrative, Tharoor exposes the absurdities of Indian democracy, leadership, and the persistence of colonial legacies in modern governance. By reinterpreting the Mahabharata as an allegory for modern Indian political history, he subverts traditional nationalist narratives, critiquing the flaws and contradictions in India’s journey from colonial rule to independence and beyond. It highlights the novel’s intertextuality, satire, and humor as postcolonial strategies that challenge colonial and neo-colonial legacies while exposing the hypocrisies of Indian democracy and leadership. Tharoor’s characters as political archetypes, representing key figures and events in India’s history. His depiction of Gandhi as Gangaji, humorously critiques the saintly image associated with him while questioning the human flaws underlying his leadership. The Great Indian Novel enriches postcolonial studies by merging myth with political critique, its dense intertextuality may challenge readers unfamiliar with Indian epics or political history.
