Authors: ADAMIV Marta , SHVALIUK Nataliia
Published: January 2025

Introduction. At the present stage, the primary condition for a company to survive and remain competitive in the market is its flexibility and readiness to restructure business processes. As a result, managers increasingly prefer more radical management approaches, such as reengineering, to traditional ones. However, domestic enterprises often face challenges in building a system for reengineering their business processes due to a lack of experience in this area. The study's relevance lies in the need to develop the theoretical and applied foundations for building a reengineering system for enterprises, which will reveal all the integral elements of this system and their unified content.
The purpose of the paper is to develop the theoretical and applied principles of building a reengineering system in enterprises.
Results. Reengineering helps solve the enterprise's existing problems, bring it to a new level of development, and ensure its stable and efficient functioning in the market in the future, based on the restructuring of business processes. Based on the literature study, it is proposed to understand the enterprise reengineering system as a set of interrelated and interacting elements, namely, subjects, objects, goals, objectives, methodology, technology, performance indicators and criteria, and resource provision, to achieve the planned results. The technology of enterprise business process reengineering includes preparation, development, and implementation phases based on the respective stages. Reengineering implementation requires high-quality resource provision, mainly information, personnel, financial, software and hardware, and material.
Conclusions. To meet the growing challenges of the modern business environment, managers are increasingly turning to radical management approaches, one of which is reengineering. To effectively implement reengineering, developing and using a systematic approach that considers all the integral elements of this process and ensures their logical and consistent interaction is advisable.
Behavioral aspects of auditor detection of fraud in financial statement audits
Authors: TUMANIAN Anna
Published: January 2025

Over the past 50 years, in the researches of foreign scientists, the issues of accounting and auditing have been considered through the theory of behavioral accounting. On the other hand, in the studies of Ukrainian scientists, behavioral accounting in accounting and auditing was almost not considered. The main meaning of the theory of behavioral accounting is not to consider accounting and auditing exclusively in numbers, but to consider that accountants and auditors are people with a specific profession who behave according to their feelings and thoughts. It is customary to consider the concept of behavioral accounting according to the following topics: the influence of accounting information on behavior, management control, audit, ethics. The paper examines the behavioral aspects of financial reporting fraud, cognitive research in accounting and cognitive styles, the impact of the auditor's cognitive style on fraud detection, ethical aspects of accountants’ and auditors' behavior, etc. The behavioral aspects of fraud from both the perpetrators and the auditor, the states of fraud, and the fraud triangle are investigated. Behavioral aspects of fraud using behavioral theories, in particular cognitivism are investigated. Thus, cognitive characteristics (abilities, cognitive style, and strategy), types of auditor cognitive styles, cognitive factors that affect auditor performance, and cognitive processes used by auditors when considering financial reporting fraud are investigated.
Evolution of legal regulation of the stock market as a factor of economic development of Ukraine
Authors: BRYHINETS Oleksandr , BIANOV Oleh
Published: January 2025

The paper thoroughly examines the evolution of the legal regulation of Ukraine’s stock market and its profound impact on the country’s economic development and investment climate. It underscores the significant role of the stock market as a pivotal mechanism for mobilizing capital in the corporate sector, fostering entrepreneurship, and creating diverse investment opportunities for institutional and individual investors. The authors emphasize that the effective functioning of the stock market is essential for economic growth, but its efficiency and stability are largely contingent upon the robustness and adaptability of its legal framework. This becomes particularly critical in a transitional economy like Ukraine, which faces the dual challenges of overcoming domestic structural inefficiencies and aligning its market regulations with international standards. The research methodology applied in the study integrates a comprehensive analysis and synthesis of contemporary academic works, legal and regulatory acts, and statistical data. In addition to the use of traditional scientific methods such as analysis, synthesis, comparison, and generalization, the authors adopt a multidisciplinary approach to explore the interplay between legislative reforms and market performance. This approach enables a deeper understanding of how the legal environment shapes investor behavior, market liquidity, and overall financial stability. The study traces the historical trajectory of reforms in the legislative framework governing Ukraine’s stock market, highlighting key milestones such as the adoption of the foundational laws «On Securities and the Stock Market» and «On Joint Stock Companies.» The paper also addresses legislative initiatives implemented in recent years, including reforms introduced between 2023 and 2024, which aim to modernize the regulatory infrastructure in response to evolving market demands and technological advancements. The authors also stress the importance of fostering international cooperation and actively participating in global economic and financial initiatives to ensure the continued integration of Ukraine’s stock market into the global financial ecosystem. In conclusion, the paper highlights the critical role of well-designed legal reforms in fostering a resilient and dynamic stock market capable of driving Ukraine’s economic modernization. The proposed recommendations offer a practical roadmap for addressing current shortcomings and unlocking the stock market’s potential as a key driver of sustainable economic growth. By adopting these measures, Ukraine can not only attract greater domestic and foreign investment but also establish itself as a competitive and innovative player in the global financial markets.
Administrative act in the system of public administration instruments: issues of definition and legal nature
Authors: TOKAR Alla , HAVRIK Roman
Published: January 2025

In the paper, the authors conducted a study of the legal nature of an administrative act in the system of public administration instruments and the content of this concept in the administrative-legal doctrine and legislation on administrative procedure. It is noted that the law of the European Union and the legislation of individual European Union states defines an administrative act through the categories of individual legal acts, administrative-legal decisions of public administration bodies and administrative contracts with their participation, that is, through the instruments of activity of public administration bodies. On the other hand, the legal acts of the Council of Europe include regulatory legal acts as administrative acts of public administration bodies. In the administrative-legal doctrine of Ukraine, as a rule, an administrative act is defined precisely through the categories of decisions and actions of public administration bodies, that is, as defined in the Law of Ukraine "On Administrative Procedure". However, there are approaches to defining the concept of an administrative act as only an individual legal act that completes administrative proceedings (primarily of the administrative-service type); as an act that also completes administrative-delict proceedings; as individual acts and acts-actions of public administration bodies; as regulatory, individual legal acts, actions of public administration bodies and administrative acts with their participation. The key to defining the concept of an administrative act is the realization of the rights and legitimate interests of participants in administrative-procedural legal relations or the creation of conditions for such realization. The paper concludes that an administrative act is individual legal acts and acts-actions of public administration bodies, which complete administrative-service, administrative-delict proceedings and implement or create conditions for the realization of the rights and legitimate interests of individuals and legal entities, the interests of the state. Regulatory and legal acts and administrative agreements do not belong to administrative acts and are independent instruments of the activities of public administration bodies.

Published: January 2025

The paper examines the theoretical and organizational foundations of participatory budget management as one of the innovative tools for involving citizens in the allocation and use of budgetary resources, democratization of the budget process at the local level to stimulate inclusive development of territorial communities.
The purpose of the paper is to develop organizational and methodological foundations for improving the management of participatory budgeting as a tool for ensuring inclusive development of the territorial community.
The study used general scientific methods of cognition (analysis and synthesis, induction and deduction); decomposition method; mathematical modeling.
Based on the results of the assessment of the national practice of participatory budgeting, the author identifies the problems of functioning of participatory budgets and substantiates the ways to solve them. In particular, an algorithm for the examination and selection of participatory budget projects is proposed, which makes it possible to take into account in this process such principles of the inclusive economy as the strategic relevance of development projects and the level of interest of project initiators in their implementation.
The authors modeled the dependence of the parameters of the participatory budget on the state of the institutional environment for the functioning of public finances, which revealed the existence of a direct correlation between budget expenditures for the implementation of publicly initiated development projects and macroeconomic dynamics, the efficiency of public administration and the rule of law. On the other hand, the effectiveness of countering corruption risks in the public sector creates preconditions for improving the quality of budget execution in terms of the compliance of its expenditures with public priorities, which “blurs” the need for participatory budgeting as a budget technology.

Las fuentes de financiamiento representan una oportunidad de crecimiento para las unidades económicas en el desarrollo de sus actividades. Esta investigación tuvo como objetivo examinar la relevancia de las fuentes de financiamiento para las MIPYMES del Municipio de Tecamachalco y su impacto en su desarrollo económico y sustentabilidad a largo plazo. Se evaluaron 225 hipótesis bivariadas mediante a) el método del coeficiente de correlación de Pearson para hipótesis lineales y b) el Contraste de Hipótesis de Chi-Cuadrado para hipótesis no lineales. Como resultado, cuatro hipótesis lineales bivariadas fueron validadas mediante el coeficiente de Pearson mayor a 0.6, y 29 hipótesis no lineales fueron validadas mediante el método de contraste de hipótesis de Chi-Cuadrado. Se concluye que las MIPYMES de la cabecera municipal de Tecamachalco, Puebla, recurren al financiamiento externo para cubrir necesidades económicas, considerando elementos como monto, tasa de interés, plazo de pago y requisitos solicitados. También se observó que la mayoría de las PYMES se abstienen de recurrir a fuentes externas de financiamiento debido a que las instituciones bancarias han establecido políticas burocráticas para solicitar un crédito, así como tasas de interés muy altas, plazos largos y montos mínimos.

An Artist within, brings out the Drawing in Class: A Creative Approach to Teaching and Learning Engineering Graphics and Design
Authors: Mthethwa Siphesihle Eugene
Published: January 2025

Allowing Engineering Graphics and Designs (EGD) learners to express themselves with music in the EGD class is part of what makes the lesson worth having. Validating learners to sing their hearts out during the lesson allows them to be willing to work on and complete their assigned EGD activities, love the subject, and long for the next lesson. This study therefore aimed to explore how an infusion of music in EGD lessons would impact teaching and learning of EGD. Some scholarly findings show that music can deeply provoke emotions, influence mood and affect cognitive performance. A qualitative approach was adopted and a purposive sampling technique where 13 grade 11 and 12 technical students doing EGD were sampled and music was infused during their EGD period. Data generated was collected using structured interviews and classroom observations. Thematically, data was analysed and responses were themed, compared, and contrasted to shed light on a creative approach to EGD and how it can enhance the teaching and learning of EGD. This study found that allowing learners to sing does give them a sense of ease and they become comfortable around the teacher. It relaxes their minds and enhances their performance. The study recommends that although the results have been positive, it also depends on the style of teaching that one uses and is comfortable to use. This study contributes towards creating enabling learning environment for EGD learners.

The Contribution of Transformative Pedagogy to the Learning Space of Scholars: A Case of South African Universities
Authors: Modiba Ngwako Solomon
Published: January 2025

This paper interrogates the contribution of transformative pedagogy and digitalized platforms to the rekindled learning space of scholars. The paper was motivated by diverse discourses and notions on the role which transformative pedagogy and digitalized platforms could play in bringing about a stimulating learning space for scholars. The paper is both conceptual and empirical in nature within the qualitative research paradigm. Interviewing techniques and documents review were employed to generate data for the paper. Research findings reveal that firstly, a transformative pedagogy with digitalized platforms encourage the development of reflective knowledge base. Secondly, they promote critical consciousness and agency within scholars. Thirdly, they encourage the engagement of scholars through participatory instructional methods. Fourthly, they make schooling a fun instead of being a burden. Fifthly, they recognise schooling inequalities and attempt to promote social justice. Lastly, a transformative pedagogy with digitalized platforms resist coercive relations of power between scholars and their lecturers. In conclusion, a transformative pedagogy with digitalized platforms prepare scholars of the 21st century to harmonise the world of schooling and the outside world of life. The researcher recommends for the embracing of a transformative pedagogy and digitalized platforms in education by virtue of them promoting an activist pedagogy that combines constructivist and critical pedagogy. The other recommendation relates to supporting the transformative pedagogy with digitalized platforms to persist to facilitate scholars to critically examine their beliefs, values and knowledge. The study emphasizes how transformative pedagogy is useful at tertiary institutions especially during tough times such as Covid-19.

The new generations of researchers are immersed in the digital world, where the management of their researcher identity is decisive for their professional career, that is where infographics act as a means of visibility. Researchers observe the use of infographics as a motivational element or reward for the work done, this given that few scientific journals use this type of graphic element for their published articles.
Suzaku Observations of the Cold Front in A3667: A Nonequilibrium Ionization State of the Intracluster Medium
Authors: Shishido Mona , Uchida Yuusuke , Kohmura Takayoshi
Published: January 2025

We present a systematic study of the thermodynamic properties of the intracluster medium (ICM), including the plasma conditions in the ICM, in the merging galaxy cluster A3667 using Suzaku. We analyze the X-ray spectra of the ICM between the northwestern and the southeastern radio relics across a prominent cold front in A3667 to search for the ICM in a nonequilibrium ionization (NEI) state. We find that the ICM inside the cold front exhibits an NEI state with an ionization parameter of (2.2 ± 0.4) × 1011 s cm−3 at the 90% confidence level, which is lower than that expected from a collisional ionization equilibrium state of the ICM (i.e., n
e
t > 1012 s cm−3). The timescale calculated from the ionization parameter of the ICM inside the cold front is

, which is much shorter than the thermal equilibration timescale. A weak transonic sloshing motion might explain the possibility that the ICM inside the cold front of A3667 is in the NEI state. In addition, the NEI state of the ICM in A3667 seems to be associated with the elongated radio halo bridging the region between the northwestern radio relic and the prominent cold front in A3667 across the cluster center.
The Effect of Stellar Evolution on Dispersal of Protoplanetary Disks: Disk Fraction in Star-forming Regions
Authors: Komaki Ayano , Yoshida Naoki
Published: January 2025

We study the effect of stellar evolution on the dispersal of protoplanetary disks by performing one-dimensional simulations of long-term disk evolution. Our simulations include viscous disk accretion, magnetohydrodynamic winds, and photoevaporation as important disk dispersal processes. We consider a wide range of stellar mass of 0.1–7 M
⊙ and incorporate the luminosity evolution of the central star. For solar-mass stars, stellar evolution delays the disk dispersal time as the far-ultraviolet (FUV) luminosity decreases toward the main sequence. In the case of intermediate-mass stars, the FUV luminosity increases significantly over a few million years, driving strong photoevaporation and enhancing disk mass loss during the later stages of disk evolution. This highlights the limitations of assuming a constant FUV luminosity throughout a simulation. Photoevaporation primarily impacts the outer regions of the disk and is the dominant disk dispersal process in the late evolutionary stage. Based on the results of a large set of simulations, we study the evolution of a population of star–disk systems and derive the disk fraction as a function of time. We demonstrate that the inclusion of stellar luminosity evolution can alter the disk fraction by several tens of percent, bringing the simulations into closer agreement with recent observations. We argue that it is important to include the stellar luminosity evolution in simulations of the long-term dispersal of protoplanetary disks.

We present results from galaxy evolution simulations with a multiphase interstellar medium (ISM), a mass resolution of 4 M
⊙, and a spatial resolution of 0.5 pc. These simulations include a resolved stellar stellar feedback model. Our fiducial run WLM-fid adopts 1051 erg for the supernova (SN) energy. Among the remaining seven simulations, there are two runs where we vary this number by fixing the energy at 1050 erg and 1052 erg (WLM-1e50 and WLM-1e52). Additionally, we carry out one run with variable SN-energy (WLM-variable) and run two simulations where only 10% or 60% of stars explode as SNe with 1051 erg, while the remaining stars do not explode (WLM-60prob and WLM-10prob). We find that the variation in the SN energy, has only minor effects: the star formation rate changes by roughly a factor of 2 compared to WLM-fid, and the strength of the galactic outflows in mass and energy is reduced by 30%, with typical values of η

 ∼ 0.1 and η

 ∼ 0.05 (at a height of 3 kpc after the hot wind is fully decoupled from the galactic ISM). In contrast, the increase and decrease in the canonical SN-energy have a clear impact on the phase structure, with loading factors that are at least 10 times lower/higher and a clear change in the phase structure (the energy loading is normalized self-consistently to the initial mass function averaged explosion energy). We conclude that these modulations are driven not by the minor change in SN-energy but rather by the likelihood of whether or not an event occurs when variable SN energies are applied.
Tempered Superdiffusive Shock Acceleration at a Perpendicular Shock
Authors: le Roux J. A. , Shikha R. K.
Published: January 2025

A theory for steady-state tempered superdiffusive shock acceleration of energetic particles at a plane perpendicular shock is presented that involves solving analytically a tempered fractional Parker transport equation for perpendicular transport in quasi-2D turbulence. The main predictions of the theory are as follows: (i) Tempered perpendicular superdiffusion (tempered Lévy flights) upstream reduces the effectiveness of classical perpendicular superdiffusion (standard Lévy flights) through a transition toward normal perpendicular diffusion when the particle transport distance upstream surpasses a critical spatial scale. Consequently, the accelerated particle distribution upstream decays spatially as a stretched exponential close to the shock that becomes a power law farther upstream under some conditions (superdiffusion), followed by an exponential rollover (transition to normal diffusion); (ii) Downstream, the accelerated particle distribution for tempered superdiffusion converges to a uniform distribution closer to the shock because of a stronger decay close to the shock compared to classical superdiffusion, and a shift of the peak in the distribution at the shock to just downstream of the shock occurs under some conditions; (iii) The accelerated power-law momentum spectrum at the shock is modulated upstream by the incoming solar wind flow to be a hardened power law instead of featuring an exponential rollover at lower particle momenta as for classical diffusive shock acceleration; and (iv) Tempered superdiffusive shock acceleration tends to be more efficient compared to standard superdiffusive shock acceleration.
The Importance of Gas Starvation in Driving Satellite Quenching in Galaxy Groups at z ~ 0.8

We present results from a Keck/DEIMOS survey to study satellite quenching in group environments at z ~ 0.8 within the Extended Groth Strip (EGS). We target 11 groups in the EGS with extended X-ray emission. We obtain high-quality spectroscopic redshifts for group member candidates, extending to depths over 1 order of magnitude fainter than existing DEEP2/DEEP3 spectroscopy. This depth enables the first spectroscopic measurement of the satellite quiescent fraction down to stellar masses of ~109.5
M
⊙ at this redshift. By combining an infall-based environmental quenching model, constrained by the observed quiescent fractions, with infall histories of simulated groups from the IllustrisTNG100-1-Dark simulation, we estimate environmental quenching timescales (τ
quench) for the observed group population. At high stellar masses (M⋆ = 1010.5
M
⊙) we find that

Gyr, which is consistent with previous estimates at this epoch. At lower stellar masses (M⋆ = 109.5
M
⊙), we find that

τ

Gyr, which is shorter than prior estimates from photometry-based investigations. These timescales are consistent with satellite quenching via starvation, provided the hot gas envelope of infalling satellites is not stripped away. We find that the evolution in the quenching timescale between 0 <z <1 aligns with the evolution in the dynamical time of the host halo and the total cold gas depletion time. This suggests that the doubling of the quenching timescale in groups since z ~ 1 could be related to the dynamical evolution of groups or a decrease in quenching efficiency via starvation with decreasing redshift.
Dynamics of Small, Constant-size Particles in a Protoplanetary Disk with an Embedded Protoplanet

Published: January 2025

Hydrodynamical simulations of protoplanetary disk dynamics are useful tools for understanding the formation of planetary systems, including our own. Approximations are necessary to make these simulations computationally tractable. A common assumption when simulating dust fluids is that of a constant Stokes number, a dimensionless number that characterizes the interaction between a particle and the surrounding gas. Constant Stokes number is not a good approximation in regions of the disk where the gas density changes significantly, such as near a planet-induced gap. In this paper, we relax the assumption of a constant Stokes number in the popular FARGO3D code using semianalytic equations for the drag force on dust particles, which enables an assumption of constant particle size instead. We explore the effect this change has on disk morphology and particle fluxes across the gap for both outward- and inward-drifting particles. The assumption of constant particle size, rather than constant Stokes number, is shown to make a significant difference in some cases, emphasizing the importance of the more accurate treatment.
Bayesian Approach to Equipartition Estimation of Magnetic Field Strength
Authors: Zychowicz Adam A. , Chyży Krzysztof T.
Published: January 2025

Magnetic fields, together with cosmic rays (CRs), play an important role in the dynamics and evolution of galaxies, but are difficult to estimate. Energy equipartition between magnetic fields and CRs provides a convenient way to approximate magnetic field strength from radio observations. We present a new approach for calculating the equipartition magnetic field strength based on Bayesian methods. In this approach, the magnetic field is a random variable that is distributed according to a posterior distribution conditional on synchrotron emission and the size of the emitting region. It allows for the direct application of the general formulas for total and polarized synchrotron radiation without the need to invert these formulas, which has limited the equipartition method to highly simplified cases. We have derived the equipartition condition for the case of different low-energy breaks, slopes, and high-energy cutoffs of power-law spectra of the CR proton and electron distributions. The derived formalism was applied in the general case of a magnetic field consisting of both uniform and randomly oriented field components. The applied Bayesian approach naturally provides the uncertainties in the estimated magnetic field strengths resulting from the uncertainties in the observables and the assumed values of the unknown physical parameters. In the examples presented, we used two different Markov Chain Monte Carlo methods to generate the posterior distribution of the magnetic field. We have also developed a web application called BMAG that implements the described approach for different models and observational parameters of real sources.
