The Tanais Bay of the Eastern Paratethys Sea at the Sarmatian–Maeotian Transition (Late Miocene): Widespread Desiccations and Local Uplifts in the Light of Historical Information
Authors: Ruban Dmitry A.
Published: July 2022

The Late Miocene evolution of the Eastern Paratethys Sea was marked by significant palaeogeographical transformations. The knowledge of them should be improved with the information from the peripheral parts of this semi-enclosed marine basin. The study area corresponds to the Rostov Dome where the northern shore of the Eastern Paratethys is widely documented. The information from the previously published work, going back to the beginning of the 20th century, is collected. Its analysis allows us to document the spatial distribution of Middle Sarmatian–Late Maeotian (Tortonian–Messinian) deposits. The results shed light into the palaeogeographical changes in the Tanais Bay of the Eastern Paratethys Sea, which included the short-term hiatus at the Middle/Late Sarmatian boundary, the Early Maeotian regression, and the gradual Late Maeotian ingression when the bay re-established, but with a different configuration. These changes and the overall spatial distribution of the studied deposits cannot be explained by only the fluctuations in the level of the Eastern Paratethys and the desiccation episodes established in its central part. Most probably, the local tectonic uplifts were an important driver of the Late Miocene evolution of the Tanais Bay.

Published: July 2022

Background: We dealt with the occurrence of an outbreak of Candida parapsilosis in a neonatal intensive care unit (NICU) in September 2020. There have been several reports of C. parapsilosis outbreaks in NICUs. In this study we describe our investigation into both the transmission route and the biofilm of C. parapsilosis. Methods: C. parapsilosis strains were detected in three inpatients and in two environmental cultures in our NICU. One environmental culture was isolated from the incubator used by a fungemia patient, and another was isolated from the humidifier of an incubator that had been used by a nonfungemia patient. To prove their identities, we tested them by micro satellite analysis. We used two methods, dry weight measurements and observation by electron microscopy, to confirm biofilm. Results: Microsatellite analysis showed the five C. parapsilosis cultures were of the same strain. Dry weight measurements and electron microscopy showed C. parapsilosis formed biofilms that amounted to clumps of fungal cells. Conclusions: We concluded that the outbreak happened due to horizontal transfer through the humidifier of the incubator and that the C. parapsilosis had produced biofilm, which promoted an invasive and infectious outbreak. Additionally, biofilm is closely associated with pathogenicity.

Published: July 2022

Background: Multiple sclerosis (MS) is a chronic, progressive neurological autoimmune disease impacting quality of life. BRISA is an app designed to help MS patients in Germany track their disease course by symptom-monitoring. This study aimed to understand demographic and health-related characteristics of BRISA users. Methods: Demographic data provided by 2095 users were analyzed to describe characteristics such as sex, age, type of MS, and medication. The distribution of tracked symptoms based on age and time since diagnosis were studied. Furthermore, the covariance of specific symptom pairs was analyzed. Results: BRISA users are predominantly female and between 26 and 55 years old. Relapsing–remitting MS was the most prevalent form of MS. First-line category 1 drugs were most frequently used, followed by high-efficacy category 3 drugs (e.g., monoclonal antibodies). The relative frequencies of use of category 1 and category 2 drugs (e.g., spingosine-1-phosphate-receptor modulators) significantly altered with time since diagnosis. Fatigue, concentration disorders, tingling, forgetfulness, and pain were the top five symptoms affecting users. Conclusion: The results highlight the diversity among MS patients and the need for extensive cohort characterization in the real-world scenario. In-depth analysis could help in identifying novel insights that could aid in disease management.
Monitoring Net Land Take: Is Mainland Portugal on Track to Meet the 2050 Target?
Authors: Nicolau Rita , Condessa Beatriz
Published: July 2022

This study discusses the situation of mainland Portugal concerning the achievement of the European “no net land take” target by 2050. This target aims to curb land take by increasing the recycling of developed land and offsetting the consumption of undeveloped land by re-naturalizing an equivalent area of artificial land. Setting targets and interventions in each country to reach this goal requires monitoring land take, developed land recycling, and re-naturalization. This study assesses these processes in mainland Portugal, by NUTS III regions, for the first time, analyzing the land cover/land use changes that occurred between 2007 and 2018. In this period, the land take rate in mainland Portugal amounted to 7.2 ha/day. Re-naturalization and recycling of developed land were 1.0 and 0.2 ha/day, respectively, showing the shortage of their practices on the mainland. During said period, mainland Portugal and most of its regions experienced a reduction in population and an increase in artificial land, revealing low efficiency in urban land use. Since Portuguese legislation does not mention the European target, we believe that most decision-makers are unaware of it or have little knowledge of the practices that can contribute to its fulfillment. In this regard, the study aims to raise awareness among policymakers and public authorities about the need to limit, mitigate, and compensate for land take and to set land take targets for different levels of action. In addition, it describes how some European countries and regions are evaluating the same processes and approaching the goal under consideration.
A Diversity of Approaches to Visual Impact Assessment
Authors: Palmer James F.
Published: July 2022

Within the broad field of landscape assessment, scholarship focused on visual impacts accounted for a very small percentage of peer-reviewed journal articles. There has been even less interest in reviewing the methods being employed to conduct visual impact assessments (VIA) as part of the development permitting process. The purpose of this review has been to show that VIA is not a uniform concept and includes a rich diversity of methods. Six diverse methods are described in some detail, including the assessment instruments, and then comments on the apparent dimensions of this diversity are made. The discussion compares the objectives, criteria, indicators, and standards used by these methods. It also considers whether the VIA is conducted using quantitative or qualitative measurements, professional or public assessors, and a geographic information system (GIS) or key observation point (KOP) framework. It concludes with a discussion of recommendations concerning identifying a gold standard against which to evaluate the VIA methods, the use of multiple methods in a VIA, and the need for research that evaluates the validity and reliability of tools and indicators as they are used in VIA.

Published: July 2022

In the process of development, traditional villages, as important tourism resources, have been impacted by external factors and lost their original authenticity. Looking for the important factors affecting its tourism development, in an attempt to assist the sustainable development of a rural destination, is Jiaju Tibetan Village in the Southwest of China. The sustainable evaluation index system divides the assessment criteria into five guideline layers: economic development, ethnic culture, management, sustainable development, and infrastructure and service facilities. The sub-criteria layer and the index layer under each of the guideline layers were refined, and matrices were constructed for various layers of indices, which calculate the weight of each indicator to produce a comprehensive score of the destination’s sustainability. The findings of this study are as follow: ➀ the Tibetan ethnic cultural life experience and the convenience of transportation are the most influential factors. ➁ Jiaju Tibetan Village is in a stage of basic sustainable development. ➂ The determinants of the indicators should be adjusted according to the tourist destination. ➃ Traditional villages should learn from each other’s tourism development experience. Finally, this study provides a reference for adjusting and formulating the tourism development strategy of ethnic traditional villages, and reasonable planning to use land, and plays an exemplary role for the development of traditional villages in concentrated ethnic minority areas.
Methodology for Identifying Ecological Corridors: A Spatial Planning Perspective
Authors: Popescu Oana-Cătălina , Tache Antonio-Valentin , Petrișor Alexandru-Ionuț
Published: July 2022

Recent studies carried out by landscape and urban ecologists have shown that habitat fragmentation has negative environmental effects and is accountable for the loss of biodiversity. The development and extension of road infrastructure to support economic growth, the urbanization and the land-use changes are major drivers of habitat fragmentation. Planners have attempted to develop tools for restoring connectivity and stopping biodiversity loss at the landscape scale and which can be applied at the urban scale, too. The study fills in the gap by developing a methodology for identifying the ecological corridors of a Romanian large carnivore (brown bear) in the Romanian Carpathian Mountains at several spatial scales. The methodology relies on geospatial data; this is equally its most important advantage and challenge. Our findings suggest that the implementation of ecological corridors in current planning practice must be completed cautiously, provided the possible restrictions are imposed on economic activities by plans, and highlight the importance of field data in increasing the scientific soundness of the results. In addition, the findings show the need to interconnect spatial planning policies with environmental policies by improving the actual legislation.
Don’t Read the Comments: Examining Social Media Discourse on Trans Athletes
Authors: Murib Zein
Published: July 2022

How are transgender athletes understood in popular discourse? This paper adapts and merges Glaser and Strauss’ 1967 Grounded Theory Method with computerized Automated Text Analysis to provide clarity on large-n datasets comprised of social media posts made about transgender athletes. After outlining the procedures of this new approach to social media data, I present findings from a study conducted on comments made in response to YouTube videos reporting transgender athletes. A total of 60,000 comments made on three YouTube videos were scraped for the analysis, which proceeded in two steps. The first was an iterative, grounded analysis of the top 500 “liked” comments to gain insight into the trends that emerged. Automated Text Analysis was then used to explore latent connections amongst the 60,000 comments. This descriptive analysis of thousands of datapoints revealed three dominant ways that people talk about transgender athletes: an attachment to biology as determinative of athletic abilities, a racialized understanding of who constitutes a proper “girl”, and perceptions of sex-segregated sports as the sole way to ensure fairness in athletic opportunities. The paper concludes by drawing out the implications of this research for how scholars understand the obstacles facing transgender political mobilizations, presents strategies for addressing these roadblocks, and underscores the importance of descriptive studies of discourse in political science research concerned with marginalization and inequality.

Published: July 2022

Atrial fibrillation is the most common presentation in adult patients with cor triatriatum sinister. The key to successful and safe catheter ablation in these patients is an accurate exploration and thorough understanding of the left atrial anatomy, both before and during the procedure. Catheter manipulation is highly dependable on left atrial anatomy, including the interatrial septum, insertion of pulmonary veins and cor triatriatum membrane. Anatomical variants such as the left common pulmonary trunk may influence the ablation approach and outcome. We report the case of a 52-year-old patient with cor triatriatum sinister and the left common pulmonary vein variant who underwent successful high-power, short-duration catheter ablation for paroxysmal atrial fibrillation.
Self-Lubricating Effect of WC/Y–TZP–Al2O3 Hybrid Ceramic–Matrix Composites with Dispersed Hadfield Steel Particles during High-Speed Sliding against an HSS Disk
Authors: Savchenko Nickolai , Sevostyanova Irina , Grigoriev Mikhail , Sablina Tatiana , Buyakov Ales , Rudmin Maxim , Vorontsov Andrey , Moskvichev Evgeny , Rubtsov Valery , Tarasov Sergei
Published: July 2022

WC/Y–TZP–Al2O3 hybrid ceramic–matrix composites (CMCs) with dispersed Hadfield steel particles were sintered and then tested at sliding speeds in the range of 7–37 m/s and contact pressure 5 MPa. Fast and low-temperature sinter-forging allowed obtaining micron-sized WC grains, submicron-sized alumina-reinforced yttria partially stabilized polycrystalline tetragonal zirconia (Y–TZP–Al2O3), and evenly distributed Hadfield steel grains. Such a microstructure provided new hybrid characteristics combining high hardness with high fracture toughness and tribological adaptation. The CMCs demonstrated low friction and high wear resistance that were better than those demonstrated by other composite materials such as, for example, MAX-phase composites, zirconia-base ceramics, ZrB2-SiC ceramics, and metal matrix WC–(Fe–Mn–C) composites. These good tribological characteristics were obtained due to the in situ mechanochemical formation of iron tungstates FeWO4 and Fe2WO6 on the worn surfaces of composite samples. These mixed oxides were included in multilayer subsurface structures that provided the self-lubricating and self-healing effects in high-speed sliding because of their easy shear and quasi-viscous behavior.

Developing an Instrument for Analyzing Mathematics and Mathematics Education Ideas in the Spanish Press of the 18th Century
Authors: Madrid María José , Maz-Machado Alexander , Cuida Astrid , Pedrosa-Jesús Cristina
Published: July 2022

Old mathematics books and textbooks have focused different researchers onto the history of mathematics and mathematics education. However, books are not the only information source for this field; for example, researchers can also study periodical-type publications from the past (such as diaries, weeklies, newspapers, etc.). Considering this, this study developed an instrument to analyze publications about mathematics and mathematics education included in newspapers, weeklies, journals, etc., which were not exclusively devoted to science, from the perspective of the history of mathematics and mathematics education. In order to do so, a descriptive research focused on the analysis of historical texts was carried out using the content analysis technique. The different labels and categories of this instrument are here exemplified by the categorization of some entries included in several periodical publications published in the 18th century in Spain.

Authors: Casas-Rosal José Carlos , León-Mantero Carmen , Jiménez-Fanjul Noelia , Gutiérrez-Rubio David
Published: July 2022

History of mathematics and mathematics education research allows us to know, among other issues: the influence that certain textbooks have had on the teaching of school mathematics, in academic or professional training, during a certain historical period; as well as the scientific advances achieved in each historical period and their incorporation into the teaching of the subject matter. In this work, we focus our attention on the applications of the method of finding maxima and minima included in the textbooks published during the 18th century in Spain. Specifically, we identify the approach of the algorithm used, the shortcomings or deficiencies that the posing of the proposed problems may have, the verification of the nature of the optimal points obtained and the consideration—or not—of the negative solutions in the process of resolution.
Local Laws for Sparse Sample Covariance Matrices
Authors: Tikhomirov Alexander N. , Timushev Dmitry A.
Published: July 2022

We proved the local Marchenko–Pastur law for sparse sample covariance matrices that corresponded to rectangular observation matrices of order n×m with n/m→y (where y>0) and sparse probability npn>logβn (where β>0). The bounds of the distance between the empirical spectral distribution function of the sparse sample covariance matrices and the Marchenko–Pastur law distribution function that was obtained in the complex domain z∈D with Imz>v0>0 (where v0) were of order log4n/n and the domain bounds did not depend on pn while npn>logβn.
Evolution over Two Decades of CAS-Active Senior Secondary Mathematics Curriculum and Assessment
Authors: Leigh-Lancaster David , Stacey Kaye
Published: July 2022

The Victorian Curriculum and Assessment Authority (VCAA) introduced the use of Computer Algebra System (CAS) technology (calculator and software) into the senior secondary mathematics curriculum and examination assessment in three phases, starting with a research-based pilot from 2000, followed by parallel implementation of CAS and non-CAS subjects from 2006 and culminating in transition to CAS-assumed subjects in 2010. This paper reports reflections on these developments over two decades from the perspectives of a researcher and the state mathematics manager (the authors) in consultation with four implementing teachers (the consultants). The authors critically examined the strategic design decisions that were made for the initiative over time. Then, with contributions from the four consultants, technical design issues relating to assessment and to teaching and the changes over a decade were investigated. A range of modifications have been made over the two decades, driven by changes in device capability and progressively increasing teaching expertise. The place of CAS in senior mathematics is now widely accepted, partly because an examination component not allowing any technology has been implemented. Examination questions have become more general, which may have added difficulty, but more questions involve setting up a real situation mathematically.
Effect of Membrane Surface Area on Solute Removal Performance of Dialyzers with Fouling
Authors: Kiguchi Takayoshi , Ito Hiromi , Yamashita Akihiro C.
Published: July 2022

In a clinical situation, since membrane fouling often causes the reduction of solute removal performance of the dialyzer, it is necessary to evaluate the performance of the dialyzer, considering the effects of fouling even in aqueous in vitro experiments that are useful for the better design of dialyzers. We replicated the membrane fouling by immobilizing albumin on the membrane in a dialyzer using glutaraldehyde as a stabilizer. The modules of various membrane surface areas with and without replication of the fouling were used for performance evaluation of solute (creatinine, vitamin B12, and inulin) removal in dialysis experiments in vitro. Clearances for these solutes in the modules with fouling were lower than those without fouling. Furthermore, the smaller the surface area, the larger the fouling effect was observed in all solutes. Calculated pressure distribution in a module by using a mathematical model showed that the solute removal performance might be greatly affected by the rate of internal filtration that enhances the solute removal, especially for larger solutes. The increase in the rate of internal filtration should contribute to improving the solute removal performance of the dialyzer, with a higher effect in modules with a larger membrane surface area.
Near-Equiatomic μ Phase in Self-Sharpening Tungsten-Based High-Entropy Alloys
Authors: Liu Tian-Wei , Li Tong , Dai Lan-Hong
Published: July 2022

The topologically close-packed (TCP) μ phase is usually known as an undesirable precipitation in highly alloyed Ni-base superalloys and steels. However, the ultrastrong μ phase with micron/nano-scale distribution plays a key role in driving the emergence of self-sharpening in our recently developed WMoFeNi high-entropy alloy (HEA). Herein, a detailed study is carried out to understand the substructure and atomic occupation of the μphase by scanning electron microscope (SEM) and aberration-corrected transmission electron microscope (ACTEM). The Fe/Ni and W/Mo element pairs are equivalent in the μ phase structure. Moreover, the elements in μ phase exhibit a near-equiatomic ratio, and the μ phase can grow during annealing at 1150 °C. (0001)μ and (11¯02)μ twins are the main substructures of the μ phase, and their atomic configurations and twinning mechanisms are investigated. The geometrical structural analysis of μ phase possesses a great significance for the design of self-sharpening HEAs.
In Silico Genomic and Metabolic Atlas of Limosilactobacillus reuteri DSM 20016: An Insight into Human Health
Authors: Smythe Paisleigh , Efthimiou Georgios
Published: July 2022

Probiotics are bacterial strains that are known to provide host health benefits. Limosilactobacillus reuteri is a well-documented lactic acid bacterium that has been cultured from numerous human sites. The strain investigated was L. reuteri DSM 20016, which has been found to produce useful metabolites. The strain was explored using genomic and proteomic tools, manual searches, and databases, including KEGG, STRING, BLAST Sequence Similarity Search, and UniProt. This study located over 200 key genes that were involved in human health benefit pathways. L. reuteri DSM 20016 has metabolic pathways to produce acetate, propionate, and lactate, and there is evidence of a pathway for butanoate production through a FASII mechanism. The bacterium produces histamine through the hdc operon, which may be able to suppress proinflammatory TNF, and the bacterium also has the ability to synthesize folate and riboflavin, although whether they are secreted is yet to be explored. The strain can bind to human Caco2 cells through srtA, mapA/cnb, msrB, and fbpA and can compete against enteric bacteria using reuterin, which is an antimicrobial that induces oxidative stress. The atlas could be used for designing metabolic engineering approaches to improve beneficial metabolite biosynthesis and better probiotic-based cures.
Nontuberculous Mycobacteria as Sapronoses: A Review
Authors: Pavlik Ivo , Ulmann Vit , Hubelova Dana , Weston Ross Tim
Published: July 2022

Mycobacteria are a unique group of microorganisms. They are characterised by exceptional adaptability and durability. They are capable of colonisation and survival even in very unfavourable conditions. In addition to the well-known obligate human pathogens, Mycobacterium tuberculosis and M. leprae, more than 200 other species have been described. Most of them form a natural part of the microflora of the external environment and thrive in aquatic and soil environments especially. For many of the mycobacterial species associated with human disease, their natural source has not yet been identified. From an ecological point of view, mycobacteria are saprophytes, and their application in human and animal diseases is opportunistic. Most cases of human disease from saprophytic mycobacteria occur in immunocompromised individuals. This adaptability and resilience to environmental pressures makes treatment of mycobacterial diseases (most often sapronoses and less often zoonoses) and permanent eradication of mycobacteria from the environment very difficult. Saprophytic mycobacterial diseases (sapronoses) are chronic and recurrent due to the fact of repeated endogenous or exogenous re-exposure. Therefore, knowledge regarding their occurrence in soil and dust would aid in the prevention of saprophytic mycobacterioses. In conjunction, their presence and ecological significance in the environment can be revealed.

Numerous health benefits have been reported from the consumption of cranberry-derived products, and recent studies have identified bioactive polysaccharides and oligosaccharides from cranberry pomace. This study aimed to further characterize xyloglucan and pectic oligosaccharide structures from pectinase-treated cranberry pomace and measure the growth and short-chain fatty acid production of 86 Lactobacillus strains using a cranberry oligosaccharide fraction as the carbon source. In addition to arabino-xyloglucan structures, cranberry oligosaccharides included pectic rhamnogalacturonan I which was methyl-esterified, acetylated and contained arabino-galacto-oligosaccharide side chains and a 4,5-unsaturated function at the non-reducing end. When grown on cranberry oligosaccharides, ten Lactobacillus strains reached a final culture density (ΔOD) ≥ 0.50 after 24 h incubation at 32 °C, which was comparable to L. plantarum ATCC BAA 793. All strains produced lactic, acetic, and propionic acids, and all but three strains produced butyric acid. This study demonstrated that the ability to metabolize cranberry oligosaccharides is Lactobacillus strain specific, with some strains having the potential to be probiotics, and for the first time showed these ten strains were capable of growth on this carbon source. The novel cranberry pectic and arabino-xyloglucan oligosaccharide structures reported here combined with the Lactobacillus strains that can metabolize cranberry oligosaccharides and produce short-chain fatty acids, have excellent potential as health-promoting synbiotics.

El actuar y los cinco sentidos en escritos del siglo XII
Authors: Ortúzar Escudero María José
Published: July 2022

Medieval writers (at least until the 12th century) certainly thought about how we know about the world and how such knowledge is attained through the five senses. Their disquisitions were aimed, though, at shedding some light on both the proper use of the five senses and their relationship to the knowledge of God. The operation of the five senses was only seldom understood as a passive recording of external impressions, most descriptions ended in considerations of the different activity of each sense or of each sense’s organ. This paper focuses precisely on sensory operation especially as it is viewed in texts by 12th century monks and canons. It also reviews how contemporary emphases such as the man as a microcosm and the renewed importance granted to the vita activa led to a definition of the senses – and of homo – that was even more perfused by human operation.

Authors: Piwowarska Ewa
Published: July 2022

Z uwagi na znaczenie działań aktywizujących i kształcących zmysł obserwacji dla czynności uczenia się u dzieci, za cel badawczy o charakterze poznawczym przyjęto ustalenie istotności czynnika podkreślającego konstrukcję obserwowanych brył dla tworzonych przez dzieci ich graficznych schematów, w tym ukazywania trzeciego wymiaru. Przyjętym problemem reprezentującym ogólny aspekt obszaru badawczego stało się pytanie o znaczenie nowego czynnika, jakim jest linia wyróżniająca krawędzie brył, dla sposobu przedstawiania za pomocą rysunku obserwowanych przez dzieci brył geometrycznych. Założono, że dla przebiegu zachodzących zmian w rozwoju rysunków brył będzie można wyznaczyć charakterystyczne etapy-schematy oraz czynnik wzmacniający proces obserwacji konstrukcji brył. Analiza zebranych danych pozwoliła zauważyć, że wprowadzony czynnik ma istotne znaczenie dla poziomu umiejętności graficznego zapisu brył geometrycznych, co może przekładać się na kształcenie zmysłu przestrzennego u dzieci. W oparciu o prowadzoną analizę porównawczą prac plastycznych powstających w sytuacji rysowania bezpośrednio obserwowanych przez dzieci zróżnicowanych białych brył (w wersjach o krawędziach zaznaczonych czarną linią i bez niej), uzyskana wiedza może zostać wykorzystana w procesie projektowania zadań edukacyjnych oraz pomocy dydaktycznych, dla których istotne jest doskonalenie percepcji wzrokowej obejmującej również trzeci wymiar rzeczywistości.

Assessing Multiplier Effects of Public Expenditures on Economic Growth in Nepal: SVAR Model Analysis
Authors: Bista Raghu Bir , Sankhi Kiran Prasad
Published: July 2022

This paper assesses the multiplier effects of public expenditures on economic growth in Nepal, covering time series data sets of public expenditures and economic growth from 1974-75 to 2018-19 by using the SVAR model. As a result of the SVAR model, the multiplier effect of public expenditure, recurrent expenditure, and capital expenditure is positive for economic growth. In a result, the multiplier effect of recurrent expenditure is found to be more promising than capital expenditure for economic growth in the short run, but in the long run, it is lower. Similarly, the multiplier coefficient value of capital expenditure is lower in the short run. This is probably due to leakages in the economy, corruption and improper management of development funds, seasonal expenditure trends, and poor management of development projects. Therefore, the government should improve the efficiency of public expenditure and the ratio of capital expenditure and private investment to improve the higher multiplier variable in the long run.

The purpose of this study is to see how company size, earnings per share, profitability, financial leverage, and underwriter reputation affect underpricing during the initial public offering of companies listed on the Indonesia Stock Exchange (IDX). This study's object was selected utilizing a purposive sample approach with numerous provisions. Non-banking firms that conducted initial public offerings (IPOs) on the Indonesia Stock Exchange (IDX) between 2015 and 2019 were researched. Ninety-eight non-banking firms were collected as study samples from a total of 141. This is due to the fact that there are six banking businesses, sixty-two companies do not meet the requirements for inclusion in this study data, and thirteen companies do not exhibit underpricing. Two firms were relisted and delisted. Based on the findings of data analysis research, low earnings per share will also make investors not interested in buying shares of the company. So the company's level of uncertainty will increase. Underwriters also know more and more complete information about the market so that issuers are needed to determine primary market prices and investors to consider investing in the capital market. Meanwhile, the level of underpricing cannot be measured by the level of ROA generated by a company and the distrust of investors towards the financial statements produced by companies that conduct IPOs. DER cannot be used as a benchmark in considering the initial return expected by investors based on the findings of data analysis research. the author assumes investors' incompetence in analyzing a company's performance and relies solely on the stock price offered. The phenomenon of stock price underpricing caused by limited information about companies conducting initial public offerings (IPOs) motivates the authors to conduct this research to determine whether the information available in financial statements and information surrounding investors can be used as benchmarks in determining investment decisions. and calculate a stock's initial rate of return.
