Abstract

Objectives
An analytical protocol based on isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS), which includes a peptide-based calibration strategy, was developed and validated for the determination of cardiac troponin I (cTnI) levels in clinical samples. Additionally, the developed method was compared with a protein-based calibration strategy, using cTnI serving as a model for low-abundant proteins. The aim is to evaluate new approaches for protein quantification in complex matrices, supporting the metrology community in implementing new methods and developing fit-for-purpose SI- traceable peptide or protein primary calibrators.

Methods
To establish traceability to SI units, peptide impurity correction amino acid analysis (PICAA) was conducted to determine the absolute content of signature peptides in the primary standards. Immunoaffinity enrichment was used to capture cTnI from human serum, with a comparison between microbeads and nanobeads to improve enrichment efficiency. Parallel reaction monitoring was used to monitor two signature peptides specific to cTnI. Various digestion parameters were optimized to achieve complete digestion.

Results
The analytical method demonstrated selectivity and specificity, allowing the quantification of cTnI within 0.9–22.0 μg/L. The intermediate precision RSD was below 28.9 %, and the repeatability RSD was below 5.8 % at all concentration levels, with recovery rates ranging from 87 % to 121 %. The comparison of calibration strategies showed similar LOQ values, but the peptide-based calibration exhibited significant quantitative bias in recovery rates. The data are available via ProteomeXchange (PXD055104).

Conclusions
This isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) method, based on peptide calibration, successfully quantified cTnI in human serum. Comparing this with protein-based calibration highlighted both the strengths and potential limitations of peptide-based strategies.

Abstract
The fabrication of a Bi(iii) oxide-Bi(iii) oxychloride/poly-m-methyl aniline (Bi2O3–BiOCl/PmMA) nanocomposite thin-film optoelectronic device capable of light-sensing across a broad spectrum, spanning both visible and ultraviolet wavelengths, has been accomplished. The synthesis of the composite has been achieved using a one-pot technique involving the direct oxidation of m-methyl aniline with ammonium persulfate ((NH4)2S2O8) in the presence of bismuth nitrate pentahydrate (Bi(NO3)35H2O). X-ray diffraction (XRD) analysis confirms the composite’s high crystallinity and compact size of 41 nm, indicative of excellent optical properties and a narrow bandgap of 2.35 eV. The optical analysis of the synthesized core–shell composite is performed using Fourier transform infrared spectroscopy (FTIR). FTIR, X-ray photoelectron spectroscopy, and XRD analysis characterize the fabricated composite’s crystalline structure. The composite has been tested electrically using the CHI608E device, demonstrating its potential for efficient light absorption and photon trapping, making it a promising candidate for advanced light sensing applications.

Abstract

The rusty-spotted cat (Prionailurus rubiginosus), the world’s smallest felid, is native to India, Sri Lanka, and Nepal. Despite its Near Threatened status on the IUCN Red List, research on this elusive species remains fragmented, focusing mainly on species distribution through incidental camera-trap data. With the development of tailored, evidence-based conservation strategies requiring sufficient knowledge of the species' biology and threats, we aim to summarize critical knowledge gaps and provide recommendations for filling them. We systematically reviewed the existing literature to assess the state of research on the species, identify key research trends, and highlight areas requiring urgent attention. Additionally, we mapped 121 occurrence records and delved into 15 conservation projects to understand current monitoring and conservation efforts throughout its range. Our findings from 52 studies indicate that most studies focus on habitat preferences and distribution, with limited research on biology, genetics, disease, and threats to the species. Major threats identified include habitat loss, fragmentation, road mortality, and potential disease risks. Occurrence records are heterogeneous in terms of the methods employed but do identify potential species range expansions in India. Most conservation projects stem from India, however, efforts in Nepal and Sri Lanka have increased in recent years, reinforcing the growing conservation importance of this species. The review underscores the need for standardized monitoring protocols, long-term targeted research, and collaborative conservation efforts across the species’ range. By addressing these gaps, we envisage the development of more robust research and conservation strategies for the rusty-spotted cat in the future.

Authors: Guriev S.O. , Skobenko E.O. 
Published: January 2025

Background. Already from the beginning of the ­COVID-19 epidemic, both in Ukraine and in the world, there was a problem of providing trauma care to victims with traumatic injuries, which was combined with similar problems with medical care for other categories of patients. The system of routing patients with hip fractures against the background of COVID-19 during the epidemic period, depending on the severity of the course, will allow to organize a system of providing medical care to such patients, which will correspond to both the personnel and material resources necessary to overcome the consequences of this pandemic. The aim of our study was to analyze the distribution of patients with femur fractures during the COVID-19 epidemic and to determine changes in approaches to their treatment. Materials and methods. To conduct our study, we retrospectively analyzed the treatment of 289 trauma patients who underwent inpatient treatment in 2019–2021. Results. The number of surgical interventions in patients with hip fractures decreased by only 2.8 %, which indicates the absence of changes in the tactics of treatment of patients with this pathology during the epidemic period. There were no changes in the number of patients with diaphyseal femur fractures; their number was constant in both research periods. However, during the epidemic period, an increase in the level of surgical interventions in patients with fractures of the diaphyseal part of the femur was found. During the COVID-19 epidemic, there was a decrease in the number of victims with fractures in the distal part of the hip. During the epidemic period, the rate of distal hip fractures decreased by 6.0 %. An increase in ope­rative activity was found in relation to patients with fractures of the distal part of the femur in the pre-operative period. Conclusions. In the period of COVID-19, the number of patients with hip fractures increased, and no changes in the structure of treatment of patients in this category were found. During the COVID-19 epidemic, there were no changes in the number of patients with diaphyseal hip fractures, their number was constant in both research periods. However, during the epidemic period, an increase in the level of surgical interventions in patients with fractures of the diaphyseal part of the femur was found. During the epidemic period, there was a decrease in the level of victims with fractures in the distal part of the thigh by 6.0 %, and an increase in operative activity was detected in relation to patients from this category.

Determinants of tax avoidance disclosure moderated by firm size
Authors: Sari Nihayatul Maula , Nurdin Fajar 
Published: January 2025

Purpose: This study aims to analyze the effect of sales growth, profitability, and inventory turnover on tax avoidance moderated by firm size.
Methodology/approach: This study uses secondary data from firm financial statements in a quantitative research approach. Companies in the real estate and property sectors that are listed on the Indonesia Stock Exchange (IDX) between 2020 and 2023 make up the population. 34 samples in all were chosen using a purposive selection technique, and moderated regression analysis (MRA) was performed using EViews software.
Findings: The study's findings show that while profitability and inventory turnover significantly reduce tax avoidance, sales growth has little influence on the practice. Firm size can minimize the impact of profitability on tax avoidance, but it has no influence on the link between sales growth and inventory turnover and tax avoidance.
Practical and Theoretical contribution/Originality: It is anticipated that the Directorate General of Taxes will use the findings from this study as a guide when evaluating corporate tax evasion. It also explains how business size influences the relationship between tax avoidance and inventory turnover, profitability, and sales growth.
Research Limitation: Because businesses have not been consistent in releasing financial reports over the 2020–2023 timeframe, and because the metrics are restricted to proxies for firm size, sales growth, profitability, and inventory turnover, this study has a narrow focus. Additionally, only publicly available secondary data specifically, financial reports are used in data collecting.

Published: January 2025

Perubahan tata guna lahan dan pemanfaatan lahan yang tidak sesuai di DAS Panasen menyebabkan terjadinya sedimentasi di danau Tondano. Pengaruh aliran sarat sedimen terhadap proses sedimentasi masih menjadi permasalahan yang perlu dikaji. Terjadinya genangan banjir pada bagian hilir sungai akibat adanya proses pendangkalan sungai merupakan permasalahan yang berdampak pada kerugian ekonomi, masalah lingkungan bahkan konflik sosial masyarakat yang belum terselesaikan. Penelitian ini bertujuan untuk mendapatkan faktor-faktor penyebab banjir dengan mengevaluasi kapasitas penampang sungai Panasen di bagian hilir serta menganalisis pengaruh aliran bersedimen Sungai Panasen terhadap proses sedimentasi di Danau Tondano. Penelitian dilakukan melalui pengamatan lapangan berupa pengukuran geometri sungai dan pengambilan sampel aliran bersedimen. Data sekunder yaitu peta topografi, data curah hujan dan data debit terukur diperoleh dari instansi terkait. Berbagai analisis yang dilakukan adalah analisis hidrologi, analisis hidraulika dan analisis sedimentasi. Analisis hidrologi menggunakan data hujan harian maksimum yang diperoleh dari pos hujan Stasiun Noongan dan debit sungai terukur dari AWLR Sungai Noongan. Besar debit banjir menggunakan model HEC-HMS dengan parameter terkalibrasi untuk berbagai kala ulang 2, 5, 10, 25, 50 dan 100 tahun masing-masing diperoleh sebesar 50.2 m3/det, 71.6 m3/det, 82.1 m3/det, 91.8 m3/det, 97.2 m3/det dan 101.4 m3/det. Dari analisis hidraulika diperoleh pada kondisi banjir Q100 dan pasang air danau, di semua segmen sungai tinjauan tidak mampu menampung debit banjir. Ketinggian muka air banjir (overflow) berada pada 1.2 – 3.1 meter dan cenderung terjadi ke arah kanan tepian sungai. Jumlah sedimen yang terangkut ditentukan setelah diperoleh kandungan sedimen terlarut yaitu sebesar 6.16 gr/m3 yang mengakibatkan rata-rata penambahan volume sedimen ke danau selama 30 tahun sebesar 3,215,104.7 m³ atau ketebalan 72.15 mm. Hasil penelitian menunjukan jumlah sedimen masuk danau yang cukup besar sehingga diperlukan upaya-upaya penanganan pada DAS sungai Panasen yaitu berupa tindakan konservasi lahan dan penetapan tata guna lahan yang tepat.

Visual Metaphor and Narrative: Ekphrasis in Fictional Narrative Prose of Late Antiquity
Authors: Paskaleva Bogdana 
Published: January 2025

Abstract
This article presents an interpretation of some functions performed by ekphrastic structures in the context of Ancient fictional narrative prose. Concrete examples are taken from two Ancient Greek novels: Daphnis and Chloe by Longus and Leucippe and Clitophon by Achilles Tatius. Using Olga Freidenberg’s conceptual and interpretative apparatus as a lens for reading the textual material, the central claim of the article is that within Ancient prose narrative, ekphrasis and metaphor are functionally interrelated, with ekphrasis serving to metaphorically embed narrative content within the mythological, affective, and genre-related fields of the textual production of meaning. At the same time, while adopting Freidenberg’s definition of metaphor as a primal state of cognitive indistinction between image and concept, the article attempts to go beyond her mythological interpretation of the Ancient novel and to provide a more socially and historically relevant understanding of the semantic features of this genre.

Authors: Rugiubei Radu , Cruceanu Sabina 
Published: January 2025

Abstract
The purpose of this study is to explore the phenomenon of quiet quitting within Romanian companies and its relationship with organizational culture, demographic factors, leadership styles, and peer/supervisor pressure. The research aims to determine how and if these characteristics influence the phenomenon of quiet quitting in any way. The findings reveal a strong association between organizational culture and quiet quitting, suggesting that the nature of an organisation’s culture directly influences employees’ inclination to consider such actions. Additionally, leadership style significantly impacted quiet quitting, indicating that managerial approaches play a pivotal role in employees’ decision-making. Furthermore, the study did not identify a substantial connection between peer influence and the relationship between corporate culture and quiet quitting. These findings emphasise the critical role of organizational culture and leadership approaches in understanding and addressing the quiet quitting phenomenon. The results highlight the need for employers to foster a positive and healthy work environment and to implement effective leadership strategies to mitigate the likelihood of employees considering quiet quitting.
Impact of the 2020 Medicaid Expansion in a Community Clinic Serving the Marshallese Population in a Rural State
Authors: Brand Robert , Robinson Samantha , Rahman Mohammod Mahmudur , Hazaa Alshaimaa , CarlLee Sheena , Jensen Hanna 
Published: January 2025

Introduction
In December of 2020, the US government passed into law a bill allowing states to enroll Compact of Free Association citizens (including citizens of the Republic of the Marshall Islands) into Medicaid. This study analyzes the impact of this expansion on the healthcare of Marshallese patients at a dedicated community clinic on a regional medical campus, serving this unique population.
Methods
Through retrospective review of patients who utilized the community clinic either before (05/2020 to 02/2021) or after (05/2021 to 02/2022) the Medicaid expansion, this study sought to compare patients’ insurance information, number of total patients visiting the clinic, number of total patient visits, referrals per patient, and completed referrals per patient were compared between time periods.
Results
A total of 378 patients utilized the clinic during the study period. The results demonstrated a significant increase in patient utilization of healthcare services (20.1% vs. 8.7%, p<0.01), percentage of clinic visits that included referrals (23.6% vs. 16.5%, p<0.01), and percentage of completed referrals following the Medicaid expansion (16.1% vs. 10.5%, p=0.03). Analyses of comorbidities indicated similar disease burden in both pre and post cohorts.
Conclusion
The study’s findings suggest an increase in the use of healthcare services following the expansion of Medicaid services to previously uninsured patients. Existing literature documents the gaps in primary care services for underrepresented and uninsured populations in the United States and the significant consequences of lack of access to care. Findings from this study can aid health policymakers in designing and implementing new strategies to increase healthcare access and utilization in target populations. Future research is needed to determine how these healthcare-related behaviors affect patient health and how expanding healthcare policies may elucidate such results on a larger scale.
