Authors: Ait Temghart Said , El Hasnae Hammar , Allalou Chakir , Hilal Khalid
Published: May 2024

In this paper, we consider the existence of weak solutions for some nonlinear
elliptic problems with perturbed gradient under homogeneous Dirichlet
boundary conditions. We apply the Galerkin approximation and the convergence
in term of Young measure combined with the theory of Sobolev spaces to
obtain the existence of at least one weak solution u ? W1,p 0 (?;Rm).

Although endothelial cells control smooth muscle tone in coronary vessels, these cells also influence subjacent cardiomyocyte growth. As heparanase, with exclusive expression in endothelial cells, enables extracellular matrix remodeling, angiogenesis, metabolic reprogramming, and cell survival, it is conceivable that it could also encourage development of cardiac hypertrophy. Global heparanase overexpression resulted in physiological cardiac hypertrophy, likely an outcome of HSPG clustering and activation of hypertrophic signaling. The autocrine effect of heparanase to release neuregulin-1 may have also contributed to this effect. Hyperglycemia induced by streptozotocin-diabetes sensitized the heart to flow-induced release of heparanase and neuregulin-1. Despite this excess secretion, progression of diabetes caused significant gene expression changes related to mitochondrial metabolism and cell death that led to development of pathological hypertrophy and heart dysfunction. Physiological cardiac hypertrophy was also observed in rats with cardiomyocyte-specific VEGFB overexpression. When perfused, hearts from these animals released significantly higher amounts of both heparanase and neuregulin-1. However, subjecting these animals to diabetes triggered robust transcriptome changes related to metabolism, and a transition to pathological hypertrophy. Our data suggest that in the absence of mechanisms that support cardiac energy generation and prevention of cell death, as seen following diabetes, there is a transition from physiological to pathological cardiac hypertrophy and a decline in cardiac function.

Published: May 2024

Objective: To describe and evaluate the combination of osseointegration and nerve transfers in 3 transhumeral amputees.
Design: Case series.
Patients: Three male patients with a unilateral traumatic transhumeral amputation.
Methods: Patients received a combination of osseointegration and targeted muscle reinnervation surgery. Rehabilitation included graded weight training, range of motion exercises, biofeedback, table-top prosthesis training, and controlling the actual device. The impairment in daily life, health-related quality of life, and pain before and after the intervention was evaluated in these patients. Their shoulder range of motion, prosthesis embodiment, and function were documented at a 2- to 5-year follow-up.
Results: All 3 patients attended rehabilitation and used their myoelectric prosthesis on a daily basis. Two patients had full shoulder range of motion with the prosthesis, while the other patient had 55° of abduction and 45° of anteversion. They became more independent in their daily life activities after the intervention and incorporated their prosthesis into their body scheme to a high extent.
Conclusion: These results indicate that patients can benefit from the combined procedure. However, the patients’ perspective, risks of the surgical procedures, and the relatively long rehabilitation procedure need to be incorporated in the decision-making.
Exploring remote work
Authors: Silva Marcos Vinicius Tassote da , Barros Neto João Pinheiro de
Published: May 2024

Remote work has been widely adopted by organizations. In this context, this study aimed to answer several questions regarding the adaptation of centennials (born after 1995) to this type of work. It is in this generation that companies seek talent to meet skill needs (creativity, innovation, leadership). This is an exploratory study that began with a literature review, followed by the application of a questionnaire created in the Google Forms© tool. The forms were sent to students in the Administration course at the Pontifical Catholic University of São Paulo (PUC-SP) via email and WhatsApp, resulting in seventy-four valid responses. The sampling of responding students was obtained through the technique known as snowball sampling. Only 28.2% stated that their productivity improved when working remotely, something that can be justified by distractions with smartphones and social networks. Another important issue was related to the time that Centennials gained in their routines, considering, for example, that they did not waste time commuting to work. In this aspect, 33.80% (24) stated that they used their time very well, 21.13% (15) used it well ("Using time well," in this context, refers to the effective utilization of time for value-generating activities, such as spending time with family, engaging in physical exercise, reading etc.). Remote work has value among centennials because it provides them with autonomy and free time. The study warns that a generation is just a generalization and that organizations will need to strive to understand that generation to get more productivity from it. The limitation of the study lies in the small number of respondents and the homogeneity of the sample; however, it does not invalidate the results and suggests the need for further studies aimed at better understanding this generation.
Walking recognition
Authors: Santos Lucineia Rosa dos , Marcilio Thiago Gomes
Published: May 2024

This article intends to analyze how walking recognition operates in a mechanical system that deals with uncertainty and the use of it to create biopolitical power. The objectives are to identify the physics theory how they connect with the philosophical approach. The hypothesis is that this system works in a structure identical to quantum physics laws. New algorithmic techniques have led to the exercise of Foucauldian biopolitical disciplinary power over bodies in the present, using uncertainties about the future as a raw source for defining interventions. Algorithmic prediction, and the panopticon model, are rooted in the desire to understand and exert power over bodies. It was found that, a predictive algorithm implies distinct temporal lines and expands time, which resonates with Schrödinger's model of possibilities and uncertainties, particularly when the observer's intervention can alter the state of affairs. While the past offers limited raw material for manipulation (as in the book "1984"), the future provides an inexhaustible speculative source of hypothetical scenarios (as in Isaac Asimov's book "Foundation") for AI, potentially diminishing the centrality of human self-determination over lives.

Published: May 2024

Climate change is directly related to global warming. Such warming is caused by high greenhouse gases emissions into the atmosphere due to anthropogenic activities. Because of this, there is a greater incidence of health problems in the population, not to mention the damage to the environment. There has been increasing debate and discussion about ways to reduce greenhouse gas emissions as a way of mitigating climate change. Given this, information and communication technologies are an important factor that can bring benefits and gains to the reduction and/or monitoring of these gases. Therefore, the current work aimed to identify information and communication technologies (ICTs) for monitoring industrial atmospheric emissions that contribute to the increase in climate change. Regarding the research methodology, it is a applied research, has a qualitative approach and in terms of its objective, it is characterized as exploratory. Regarding the results, it was proven through practical examples in companies that it is possible to use ICTs to minimize and/or mitigate the emission of atmospheric pollutants. Therefore, it is concluded that technologies can combat the causes of climate change within companies and even smart cities.

Authors: Andervazh Leila , Ghorbanpour Mousa Zalaki
Published: May 2024

This research was designed to examine the effect of using social media technology on improving participation and customer satisfaction in the banking industry due to the mediating role of value perceived by customers of the studied banks. The present study was an applied and descriptive-surveying research in terms of objective and methodology, respectively. The research statistical sample consisted of 235 senior managers of state and private banks in the banking industry of Iran. A questionnaire was employed to collect the research data, and its validity and reliability were con and Cronbach's alpha indices. The structural equation modelling method was used in the SmartPLS software to test the research hypotheses once the data was gathered. The results of testing the hypotheses demonstrated that the use of social media technology has a positive impact on improving participation intention, satisfaction, and value perceived by customers of the studied banks, which directly predicts 0.486, 0.551, and 0.568 of changes related to the participation intention, satisfaction, and perceived value, respectively. The results analysis also revealed that social media technology has a positive impact on participation intention and customer satisfaction through the value perceived by customers. Hence, the use of social media technology through the mediating variable indirectly predicts 0.517 and 0.449 of changes related to participation intention and customer satisfaction, respectively. Accordingly, one may acknowledge that the studied banks can move towards sustainable improvement of customer participation and satisfaction by accurately utilizing social media technology such as social networks aimed at boosting the continuous relationship with their customers as well as improving the capabilities of customer relationship management by related technologies.
How management information systems might add value to the decision-making process in organizations
Authors: Souza Lucas Almeida de , Barros Manoel Joaquim F. de , Melo Paulo
Published: May 2024

The management information systems are a fundamental issue of the decision-making process in any organization. So, the main motivation for this study was to understand how management information systems might or might not add value to the decision-making process within organizations. To carry out this study, authors have mainly focused on key concepts such as “Management Information System (MIS)” and “decision-making process” through an extensive review of bibliography and papers seeking to delimitate the state of art regarding the identification of their theoretical frameworks. The literature review confirmed that the main mechanism in which management information systems might add value to the decision-making process goes beyond the process itself, helping organizations to make better decisions based on data not on guesses. Another conclusion is that, while strengthening and improving the managers’ decisions, it facilitates and improves communication and collaboration. They seem to play a crucial role in enhancing the decision-making process having impact in the organizations’ performance at all levels.  Finally, for suggestions of future studies, researchers should analyze more deeply the effectiveness of the three performance indicators for measuring such contributions of MIS to the decision-making process: speed, precision, and complexity.

Published: May 2024

Introduction: Antimalarial is listed among the most common type of live saving medicines that are counterfeited. In Nigeria counterfeited antimalarial continue to pose a great threat to the health of the citizens and there is the need to assess its incidence within the country’s six zones. This study assessed the prevalence of counterfeited antimalarial within the six geographical zones of Nigeria and the impact of zones on counterfeiting using a machine learning model for classification. Methodology: Secondary data on 2442 antimalarial collected from all the states in Nigeria were grouped based on geographical zones. The medicines were tested for originality using the gold approach for detection of counterfeit medicine; the Standard Scientific Laboratory (SSL) Data was separated to 70% training and 30% testing and 10- fold Cross Validation (CV) was performed. The training set was used to derive the models while the test set was used to evaluate the performance of the models. Three varieties of the training data were generated using the Synthetic Minority Oversampling Technique (SMOTE). This was done to ensure a more accurate prediction and a better model performance. Binary Logistic Regression (BLR) models were thereafter fitted to the training data and the three varieties of its resampling. The four models namely M1, M2, M3 and M4 were fitted with data containing 33%, 40%, 45% and 50% of the counterfeited antimalarial class respectively. The performance of the four fitted models were assessed with metrics like sensitivity, specificity and model accuracy. Results: The results showed that there is a higher incidence of counterfeited antimalarial in the north-east and south-east zones than in the other four zones of Nigeria. The work also revealed model accuracies of 67%, 65.8%, 65.8% and 56,8% for M1, M2, M3 and M4 respectively. M1 was biased as it did not correctly predict any counterfeited antimalarial. M2 and M3 performed better than M4 in terms of model accuracy and specificity while M4 performed better only in terms of model sensitivity. Conclusion: Overall, only 66% of antimalarial was correctly predicted by the best performing model. This suggest that zone alone is not adequate to classify or predict originality/counterfeiting status of Antimalarial in Nigeria.

Published: May 2024

Objectives: The aim of this study is to determine the topographic position of the corona mortis on fresh cadavers and also to determine anatomical landmarks that will facilitate surgeons to consider to this structure during operations by clarifying the relationship of the corona mortis with the surrounding anatomical structures. Methods: A total of 50 autopsy cases of 31 men and 19 women, all examined within 24 hours post-mortem, were evaluated bilaterally for the presence of corona mortis. When identified, the vascular characteristics (arterial/venous) of the corona mortis were documented. The topographic position of the corona mortis was determined by measuring the distances to the pubic symphysis, promontory, obturator nerve and anterior superior iliac spine. The study also investigated whether some anthropometric measurements affect these distances. Results: Out of the 100 hemipelves examined, corona mortis were observed in 50 cases. Among these, 34% were arterial (n=17), and 66% were venous (n=33). Anastomoses were identified in the hemipelves of 22 women and 28 men, with no significant gender difference (p>0.05). The average distances to anatomical landmarks were as follows: 5.43 cm to the pubic symphysis, 1.77 cm to the obturator nerve, 9.87 cm to the promontory, and 10.56 cm to the anterior superior iliac spine. Conclusion: Corona mortis poses a significant risk in surgical procedures. Knowing the vascular anatomy of the pelvis is vital for gynecological, urological and orthopedic interventions, while investigating deaths caused by pelvic trauma is important for forensic practice. This anatomical study contributes to a better understanding of the complex and intricate pelvic structure.

The Contribution of Czechoslovakia to Creation of the Independent State of Israel
Authors: Taterová Eva
Published: May 2024

This article examines the diplomatic relations between Czechoslovakia and the Zionist movement during the late 1940s in regard to Czechoslovakia's contribution to the establishment of the State of Israel in May 1948. The support provided by Czechoslovakia, both diplomatically and militarily, played a pivotal role in the formation of an independent Jewish state. Notably, this assistance continued even after Czechoslovakia underwent a political regime change following the communist coup d'état in February 1948. The article aims to unravel the reasons behind this exceptional cooperation between two seemingly distant actors, both geographically and ideologically. Drawing upon recently disclosed archival collections from the relevant Czech archives and providing the insight to the foreign policy of a Soviet satellite, this research aligns with the historiographic paradigm known as the New Cold War History. By focusing on the contributions of satellite states to Cold War history, it sheds light on Czechoslovakia's significant role in shaping the geopolitical landscape of the Middle East in late 1940s. Even though it might have been a somewhat marginalized story in the later decades of the Cold War due to the affiliation of the two countries with opposite ideological blocs, the history of Czechoslovakia's contribution to the creation of the State of Israel is now recognized as one of the significant narratives in the mutual relations between the two states, demonstrating the importance of past-present linkages.
Russian Active Measures in Cyberspace through the Lens of Security Sectors
Authors: Pačková Miroslava
Published: May 2024

This article examines Russian active measures in cyberspace, focusing on the implications for across security sectors. Initially, the study contextualizes the increasing reliance on cyberspace for conducting subversive activities that target military, political, societal, and economic structures, particularly after the Ukrainian Euromaidan in 2013. Utilizing a qualitative analysis of open-source data, the research identifies the diverse tactics employed by Russian actors, including sophisticated use of code and content to manipulate public perception and governmental processes. Key findings reveal that while activities in the military and political sectors are characterized by a high degree of technological sophistication, societal sectors predominantly face threats from disinformation campaigns. Notably, no significant cyber active measures were detected within the environmental sector. The study concludes that Russian cyber tactics are deeply embedded in their broader geopolitical strategy, necessitating robust countermeasures. Enhanced cybersecurity policies and international cooperation are recommended to bolster resilience against such foreign malign influences.
Islamic Factor in Foreign Policy of the Russian Federation

Published: May 2024

In the contemporary international arena, religion plays an increasingly pivotal role in shaping diplomatic strategies. This paper investigated the growing significance of Islam in shaping the foreign policy of the Russian Federation, aiming to examine the ways in which the religious factor is included in Russia's foreign policy and the tools the Russian Federation uses to defend its interests abroad through Islam. Our study, structured into three chapters, provided insights into the multifaceted role of religion in Russian foreign policy, as well as the specific ways in which the Islamic dimension influences it. Additionally, it presented selected activities carried out by Islamic religious organizations with the aim of supporting the country’s foreign policy. We found that Russia integrates religious considerations into its diplomatic initiatives and employs Islam as a tool to advance its interests globally. Russian religious leaders, aligning with the country's rhetoric of patriotism, traditional values, and antagonism towards the West, play a crucial role in legitimizing domestic and foreign policy agendas and effectively complement state authorities involved in Russia’s foreign policy. While the impact of Islam on Russia's foreign policy is significant, its evolving potential remains subject to ongoing developments and challenges. The compatibility of religious imperatives with the complexities of multi-religiosity and political elites within the Russian Federation continues to be a topic of exploration.

Considering the reliability of gas supply to power plants in the analysis of electric power system adequacy
Authors: Dzyubina T. V. , Ilkevich N. I.
Published: May 2024

One of the promising directions for further development of the methodology for investigating and ensuring the reliability of energy systems is the consideration of integrated energy systems. This is caused by the need for the adequate reflection of their joint operation. Previously, the authors proposed several methodological approaches based on "node," "system," and "evaluation" to assess the adequacy of an electric power system when this is operating jointly with a gas supply system. In that case, the focus was made only on high-pressure gas supply systems (simplified calculation). This work aims to consider not only the high-pressure gas systems, but also to take into account the influence of lowpressure gas systems (refined calculation) on the adequacy of electric power system. This approach appears to be more technologically advanced and corresponds to the real conditions of the functioning of integrated power systems. The studies were carried out using the “node” approach, its reference calculation being the most accurate one. The methods applied in the research are probability theory and mathematical statistics: a particular theorem on the repetition of experiments (Bernoulli's trial), calculation of probability distribution series, theorems of addition and multiplication of probabilities. A comparative analysis of reference calculations of the electric power system adequacy was carried out for simplified and refined connection schemes in the gas system (two cases were considered: a highly reliable low-pressure gas system and a low-reliability one). The calculations were performed on an illustrative example of a power system. Assessment of the load supply reliability in integrated systems must factor in the process features of the systems at issue, the block diagram of their connections, as well as the accuracy of the results obtained and the complexity of searching and preparing initial data for the corresponding research model.
Mining in Russia. Cryptocurrencies as investment
Authors: Brazhnikov A. E. , Panushkin V. G.
Published: May 2024

In modern conditions, when parity international financial and monetary relations are turning from traditional instruments of economic interaction into instruments of neocolonial political pressure and blackmail of economically strong countries against weaker ones, the need for a new global financial order and monetary standard, that would be independent of the will of any central bank, but with a value as reliable as that of modern fiat currencies, is increasingly realized. Today, the global economy feels the urgent need for fundamentally new opportunities for market interaction and monetary exchange. Cryptocurrencies have become such tools — electronic decentralized money issued by specific individuals in specialized open computer networks through the transformation of electricity into fixed computer codes. The process of such transformation is called mining, which uses ASIC miners as computer equipment to obtain cryptocurrency. The concept of cryptocurrencies and the specifics of investing in them are considered. The characteristic is presented of the current state and dynamics of the development of the crypto market. The possibilities and methods of forecasting the development of the cryptocurrency market are shown both using classical methods of economic forecasting and a fundamentally new methodology based on the current assessment of the psychological state of participants in the crypto market and their readiness to commit certain economic actions. An assessment is given of the possibilities of investing in mining as a technology for mining cryptocurrencies. Requirements to special mining equipment — ASIC miners — are described. An assessment is given of the prospects for the development of the crypto economy.

The structure of the company is considered, the characteristics of the main elements of the power grids under study are given, the balance of the electric energy transmission in and out of the company's networks is estimated. Based on the information published in public media on the accident rate in the company's power grids, assessment was made of the number of emergency situations that occurred over the period under study, assessment of the duration of interruptions in power supply to consumers, as well as the amount of undersupplied electric energy caused by these interruptions. The influence of the seasonal component on the number of emergencies during the period under study is considered. Based on the 2022 data, the analysis of the main causes of damage to components of power grids and the classification of failures are presented, their main characteristics over the period in question are considered. The percentage ratio of the number of failures for the most characteristic reasons to the total number of shutdowns over the period under study was established, and the classification of the number of emergency shutdowns according to the degree of undersupply of electrical energy was made. General scientific methods, numerical methods of analysis, methods of the electrical circuit theory were used in the study. To visualize the results of the analysis, the technologies of the MATLAB graphics editor were used. The results obtained may be of interest to the heads of power grid companies, as well as researchers and engineers engaged in research in the field of power supply reliability.

Vegferð ungs fólks til fullorðinsára í gegnum framhalds- og háskólakerfið er ferli sem mótar sjálfsmynd þeirra, möguleika og stöðu meðal jafningja. Markmið rannsóknarinnar er að greina stofnanahátt aðgangsstífra bóknámsskóla á Íslandi og í Finnlandi út frá bakgrunni og reynslu nemenda og skoða vegferð þeirra milli framhalds- og háskólastigsins. Nemendurnir hafa verið valdir úr stórum hópi ungmenna til að verða „úrvals“ eða „framúrskarandi“ fólk. Fræðileg nálgun er byggð á hugtökum Bourdieu þar sem rýnt er í upplifun nemendanna af ferlinu við að velja og vera valin inn í skólann, hvernig þau hafa upplifað skólavistina og svo hvernig námsvalið, skólareynslan og val á háskólanámi markast af arfbundnu auðmagni og stofnanahætti skólans. Skoðuð var upplifun stúdentsefna úr fjórum framhaldsskólum við lok námstímans í gegnum hálfstöðluð einstaklingsviðtöl við 20 nemendur. Niðurstöðurnar benda til að stofnanaháttur skólanna sé keimlíkur en finnsku nemendurnir þurftu þó að laga sig meira að afar þröngum akademískum viðmiðum. Samræmt stúdentspróf og þröng inntökuskilyrði finnska háskólastigsins skapa þar mikið aðhald. Stofnanaháttur skólanna fól í sér aðgengi að auðmagni sem nemendur gátu notað til að skapa sér yfirburðastöðu í félagsheimi ungmenna og nauðsynlega yfirsýn og þekkingu á framtíðarmöguleikum um frekara nám og störf. Niðurstöður gefa vísbendingar um að stofnanaháttur framhaldsskólanna skapi, ásamt arfbundnu auðmagni, forsendur fyrir tilteknum smekk og aðgengi að háskólanámi og mærum sem styðji við félagslegt viðhald mismununar.
Stigveldi framhaldsskóla

Íslensk menntastefna leggur áherslu á jafnrétti til náms og inngildingu. Þrátt fyrir það geta framhaldsskólar sett sín eigin inntökuskilyrði og sumir þeirra velja inn nemendur út frá bóklegri frammistöðu við lok grunnskóla. Hefðbundnir bóknámsskólar hafa sterkari samkeppnisstöðu í vali á nemendum en framhaldsskólar sem bjóða bæði upp á bók- og starfsnám (blandaðir skólar). Markmið rannsóknarinnar er að kortleggja hvort og þá hvernig skóla- og námsleiðaval viðheldur félagslegri lagskiptingu og mismunun í íslensku samfélagi í andstöðu við gildandi menntastefnu. Greind voru áhrif skólavals á samsetningu nemendahópa framhaldsskóla höfuðborgarsvæðisins með tilliti til félags- og efnahagslegs bakgrunns nemenda, fyrra námsgengis í bóklegum greinum og væntinga um háskólanám. Sömu þættir voru skoðaðir meðal nemendahópa eftir því hvort þeir voru í bóknámi eða starfsnámi. Byggt er á gögnum úr langtímarannsókn á nemendum fæddum 1999. Þátttakendur svöruðu spurningalista við lok grunnskólagöngu sinnar árið 2014 (82% af þýði). Í framhaldinu voru upplýsingar um einkunnir á samræmdum prófum í 10. bekk og skráningu í framhaldsskóla tengdar við. Niðurstöðurnar sýna skýrt mynstur skóla- og námsleiðavals sem viðheldur félagslegri lagskiptingu. Sumir framhaldsskólar velja inn nemendur út frá góðum námsárangri í bóklegum greinum og blandaðir skólar eru ekki þar á meðal. Fyrirkomulag inntöku leiðir til ólíkrar samsetningar nemendahópa eftir skólum. Í þeim skólum þar sem valið er úr nemendum er staða hópsins ekki einungis sterkari námslega heldur einnig félags- og efnahagslega auk þess sem hópurinn er líklegri til að stefna á háskólanám. Sambærilegar niðurstöður komu fram eftir námsleiðum þar sem nemendahópar í bóknámi stóðu betur að vígi en nemendur í starfsnámi. Niðurstöðurnar sýna því skýrt stigveldi framhaldsskóla og námsleiða þar sem félagslegri lagskiptingu er viðhaldið af inntökukerfi sem stangast á við yfirlýst markmið íslenskra menntayfirvalda um jafnrétti til náms og inngildingu.

In the article an interactive text-reading platform based on the Text 2.0 framework is presented. An experiment was carried out to investigate the reading behaviour of Italian language learners using this platform. Average reading time and comprehension scores did not differ across the conditions (a dedicated eye tracker PCeye Go, webcam-based eye tracking and mouse-only interaction). Additionally, participants in all the groups rated high on the perceived usefulness of the developed platform and overall reading experience. The implications of using such a tool for interactive reading are presented in this paper.
Construction and validation of a financial risk prediction model for e-commerce enterprises oriented to financial sharing
Authors: Wang Sheng
Published: May 2024

Relying on advanced technology, the financial shared management model realizes a breakthrough for the enhancement of enterprise financial management capability, and provides effective support for enterprise decision makers while mining financial risks. In this paper, the support vector machine algorithm (SVM) is used to construct a financial risk prediction model for e-commerce enterprises, and the radial basis kernel function (RBF) is selected among various kernel functions to enhance the discriminative ability of SVM. At the same time, the particle swarm algorithm (PSO) is introduced to optimize parameter γ and penalty factor C of the RBF kernel function, and the PSO-SVM fusion model is constructed, so as to improve the prediction accuracy of the e-commerce enterprise financial risk prediction model. After the experimental analysis of this paper on the various capabilities of enterprise financial management, it is found that the operating cash flow ratio of the e-commerce enterprise is less than 40% in 2017-2021, and reaches a minimum of 3% in 2020, which indicates that the Z e-commerce enterprise has insufficient ability to raise debt to operate, which may cause problems such as a decrease in the rate of return on assets. In addition, the cash flow of the e-commerce enterprise is highly variable, and the cash outflow from operating activities is significantly higher than the cash inflow in 2020, resulting in a negative net inflow of −111,451,575,000 yuan. It indicates that the Z e-commerce enterprise has a low degree of control over cash flow, and there is a financial risk of a sudden break in the capital chain. Therefore, the risk prediction model constructed in this paper can uncover potential hidden financial dangers and risks by analyzing the financial data of e-commerce enterprises.
