Mental Health and Crime: Exploring the Link

This paper discusses the complex connection present in factors of mental health and criminality in people, or how various psychological disorders may shape the inclination towards crime and the manner in which crime is dealt with by the justice system. We critique and evaluate literature catered towards various aspects such as the extent of mental illness in offenders, the influence of mental conditions on making decisions and addressing the factors related to mental illnesses that may hinder rehabilitation such as stigma. To add on, we assess in what ways such sociocultural structures as socio- economic positioning, and availability of mental care, relation to crime and mental health. Using a transdisciplinary perspective, we seek to develop implementation strategies and proposals that would serve people with mental health illness in correctional facilities, in a way that would not compromise fairness and encourage rehabilitation. The data indicate that enhancing mental health services and embedding mental health care into the criminal justice system can minimize the rates of reoffending and beneficially impact individual’s lives as well as the overall society.

Analysing the Impact of Socioeconomic Factors on Mental Health Differences in Chinese Society: Integrating Cultural, Psychological and Technological Perspectives.

Mental health (MH) differences remain an issue in contemporary Chinese society, with various factors influencing individuals' well-being. This study investigates the complex connection between results related to psychological wellness and social issues, integrating cultural, psychological and technological perspectives. Through a quantitative research methodology, data were collected from 1000 individuals using a questionnaire survey and analysed using SPSS software. The study's findings shed light on the impact of socioeconomic status (SES) on MH stigma, help-seeking behaviour and overall well-being. The findings identify that lower SES was associated with heightened levels of MH stigma and decreased the search for assistance actions. Cultural beliefs emphasising MH stigma and societal expectations were identified as mediators in the connection involve SES and MH outcomes. Digital technology use emerged as a moderator, indicating that higher levels of technology utilisation were linked to reduced disparities in accessing MH resources. The novelty of this study lies in its comprehensive examination of the multifaceted factors influencing MH disparities within Chinese society. Additionally, psychological factors such as resilience and social support were observed to mitigate the negative lower SES's effect on MH consequences. The interaction between SES and cultural factors was found to predict MH outcomes, with lower SES exacerbating the effects of MH stigma and cultural barriers.

Relationships between abiotic factors, foliage chemistry and herbivory in a tropical montane ecosystem.

Herbivore-plant interactions are fundamental processes shaping ecosystems, yet their study is challenged by their complex connections within broader ecosystem processes, requiring a nuanced understanding of ecosystem dynamics. This study investigated the relationship between nutrient availability and insect herbivory in the Australian Wet Tropics. Our objectives were threefold. Firstly, to understand what factors influence nutrient availability for plants and herbivores across the landscape; secondly, to investigate how trees of different species respond to nutrient availability; and thirdly, to unravel how the relationships between resources and plant chemistry affect herbivory. We established a network of 25 study sites covering important abiotic gradients, including temperature, precipitation, and geology. Employing a hierarchical modelling approach, we assessed the influence of climate and geology on resource availability for plants, primarily in the form of soil nutrients. Then, we explored the influence of the above factors on the interaction between herbivory and foliage chemistry across three widespread rainforest tree species, comparing how these relationships emerged across genera. Our findings suggest an overarching influence of climate and geology over soil chemistry, foliar nitrogen, and insect herbivory, both directly and indirectly. However, individual constituents of soil fertility showed equivocal influences on spatial patterns of foliage chemistry once site geological origin was accounted for, suggesting a questionable relationship between individualsoil nutrients and foliar composition. We have demonstrated that herbivore-plant interactions are complex dynamics regulated by an intricate web of relationships spanning different biogeochemical processes. While our results provide some support to the notion that herbivory is affected by resource availability, different species growing under the same conditions can show differing responses to the same resources, highlighting the importance of identifying specific limiting factors rather than simpler proxies of resource availability.

A coronary coronary-to-coronary fistula around the main pulmonary artery.

Coronary-to-coronary fistulas are rare anomalies, often detected incidentally. These fistulas may involve complex vascular connections around major cardiac structures, such as the pulmonary artery. Functional assessments help determine clinical significance, with management typically involving observation for asymptomatic patients, while symptomatic cases may require intervention to prevent complications.

Impact of Academic Progress on the Mental Health of Young People in Nigeria: A Case Study of Undergraduate Students in South-Western Nigeria

Background: Education is important in forging a pathway to economic opportunity and social mobility. It is widely regarded as a fundamental human right and a cornerstone of personal and social development. Method: This descriptive cross-sectional study employs a quantitative data collection approach. Four hundred individuals were interviewed using semi-structured, interviewer-administered questions through a multi-stage sampling technique. After data analysis with SPSS version 26, a chi-square test statistic was employed to determine whether there was a significant relationship between the categorical variables, with a p-value of less than 0.05. Results: Out of 400 respondents, 211 (52.8%) male and 189 (47.2%) female were questioned. Nearly half of the respondents (49.0%) were between the ages of 19 and 21 years old. According to the survey, most of the respondents (70.0%) asserted that their current academic workload is heavy, while (18.0%) and (9.0%) described their workload as moderate and light, respectively. Additionally, (60.0%) of the respondents rated their overall academic performance as good. However, only (13.0%) acknowledged that academic pressure contributes to stress and anxiety in life and (79.0%) occasionally expressed stress related to academic demands. About (11.8%) and (8.8%) of the respondents reported having been diagnosed with a mental health disorder before and experienced symptoms of depression in the past month respectively. An additional (20.0%) of respondents reported having experienced depression, while (24.5%) and (23.5%) claimed to have experienced anxiety and stress, respectively. Moreover, (11.8%) reported experiencing panic attacks, and (5.3%) mentioned having had suicidal thoughts. More than half of the respondents used to exercise (59.0%) and engaged in hobbies or interests (56.5%) as coping mechanisms for academic stress. Additionally, (45.5%) practiced mindfulness or relaxation techniques, and (25.5%) sought social support to manage their academic stress. About (32.5%) of respondents claimed they were aware of mental health support services available at their institutions, compared to (67.5%) who were unaware of these services. Of those aware, (33.1%) had utilized mental health support services. Additionally, (44.2%) of respondents were satisfied with the mental health support services on campus, while (39.5%) were very satisfied. The study also reveals that there’s no statistically significant association between the age, gender, monthly upkeep of the respondents and utilization of mental health support services. Conclusion: There is a complex connection between academic performance, psychological well-being, and the use of coping strategies and mental health support services among university students. This underscores the importance of addressing students' mental health needs alongside providing academic assistance.

Assessing Watershed Flood Resilience Based on a Grid-Scale System Performance Curve That Considers Double Thresholds

Enhancing flood resilience has become crucial for watershed flood prevention. However, current methods for quantifying resilience often exhibit coarse spatiotemporal granularity, leading to insufficient precision in watershed resilience assessments and hindering the accurate implementation of resilience enhancement measures. This study proposes a watershed flood resilience assessment method based on a system performance curve that considers thresholds of inundation depth and duration. A nested one- and two-dimensional coupled hydrodynamic model, spanning two spatial scales, was utilized to simulate flood processes in plain river network areas with detailed and complex hydraulic connections. The proposed framework was applied to the Hangjiahu area (Taihu Basin, China). The results indicated that the overall trend of resilience curves across different underlying surfaces initially decreased and then increase, with a significant decline observed within 20–50 h. The resilience of paddy fields and forests was the highest, while that of drylands and grasslands was the lowest, but the former had less recovery ability than the latter. The resilience of urban systems sharply declined within the first 40 h and showed no signs of recovery, with the curve remaining at a low level. In some regions, the flood tolerance depth and duration for all land use types exceeded the upper threshold. The resilience of the western part of the Hangjiahu area was higher than that of other regions, whereas the resilience of the southern region was lower compared to the northern region. The terrain and tolerance thresholds of inundation depth were the main factors affecting watershed flood resilience. The findings of this study provide a basis for a deeper understanding of the spatiotemporal evolution patterns of flood resilience and for precisely guiding the implementation and management of flood resilience enhancement projects in the watershed.

Cross border population movements across three East African states: Implications for disease surveillance and response.

The frequent population movement across the five East African Countries poses risk of disease spread in the region. A clear understanding of population movement patterns is critical for informing cross-border disease control interventions. We assessed population mobility patterns across the borders of the East African states of Kenya, Uganda, and Rwanda. In November 2022, we conducted Focus Group Discussions (FGDs), Key Informant Interviews (KIIs), and participatory mapping. Participants were selected using purposive sampling and a topic guide used during interviews. Key informants included border districts (Uganda and Rwanda) and county health officials (Kenya). FGD participants were identified from border communities and travellers and these included truck drivers, commercial motorcyclists, and businesspersons. During KIIs and FGDs, we conducted participatory mapping using Population Connectivity Across Borders toolkits. Data were analysed using thematic analysis approach using Atlas ti 7 software. Different age groups travelled across borders for various reasons. Younger age groups travelled across the border for education, trade, social reasons, employment opportunities, agriculture and mining. While older age groups mainly travelled for healthcare and social reasons. Other common reasons for crossing the borders included religious and cultural matters. Respondents reported seasonal variations in the volume of travellers. Respondents reported using both official (4 Kenya-Uganda, 5 Rwanda-Uganda borders) and unofficial Points of Entry (PoEs) (14 Kenya-Uganda, 20 Uganda-Rwanda) for exit and entry movements on borders. Unofficial PoEs were preferred because they had fewer restrictions like the absence of health screening, and immigration and customs checks. Key destination points (points of interest) included: markets, health facilities, places of worship, education institutions, recreational facilities and business towns. Twenty-eight health facilities (10- Lwakhakha, Uganda, 10- Lwakhakha, Kenya, and 8- Cyanika, Uganda) along the borders were the most commonly visited by the travellers and border communities. Complex population movement and connectivity patterns were identified along the borders. These were used to guide cross-border disease surveillance and other border health strategies in the three countries. Findings were used to revise district response and preparedness plans by strengthening community-based surveillance in border communities.

Brain-derived neurotrophic factor modulation in response to oxidative stress and corticosterone: role of scopolamine and mirtazapine

Major Depressive Disorder (MDD) is a very complex disease, challenging to study and manage. The complexities of MDD require extensive research of its mechanisms to develop more effective therapeutic approaches. Crucial in the context of this disease is the role of brain-derived neurotrophic factor (BDNF) signaling pathway. AimThis manuscript aims to explore the complex relationship between MDD and BDNF signaling pathway, focusing on how BDNF is modulated in response to oxidative stress and corticosterone, known to be altered in MDD and contributing to the pathology of the disorder, when treated with scopolamine and mirtazapine. MethodsTo assess BDNF levels after the different treatment conditions, rat hippocampal slices and mice primary hippocampus and cortical cell culture were analyzed by immunofluorescence and Western blot. Key findingsBoth mirtazapine and scopolamine under stress conditions induced by hydrogen peroxide (H2O2) and corticosterone, had a significant impact on BDNF levels, and this was distinct in different neuronal models. Mirtazapine, especially when combined with H2O2, altered BDNF expression. Scopolamine when combined with both stressors also altered BDNF levels. However, its effects varied depending on the specific neuronal model and stress condition. In accordance with BDNF results, phosphorylated tropomyosin receptor kinase B (pTrkB) presented increased activation when neuronal cells subjected to stress were treated with mirtazapine or scopolamine. SignificanceCollectively, this study highlights the complex connection between these compounds, stress conditions, and BDNF/TrkB modulation, supporting the potential therapeutic effects of scopolamine and mirtazapine in modulating BDNF levels, even in stressful conditions.

Impact of space utilization and work time flexibility on energy performance of office buildings

This study investigates the impact of different space utilization on energy use intensity, heating load, cooling load, and thermal comfort of occupants using a combination of empirical data gathering and simulation-based studies. The increasing worldwide preoccupation with energy consumption and environmental sustainability has led to increased attention on optimizing interior spaces to mitigate total energy demand. The considered case study for conducting this research was the Norwegian living lab namely Zero Emission Building (ZEB) Flexible Lab in Trondheim, Norway. In this study, 10 different scenarios of occupancy schedules based on flexible arrangements from standard workweeks to extensive remote work configurations were designed and analyzed using IDA ICE 5.0. The findings demonstrate significant reductions in energy use across scenarios with increased teleworking and compressed work weeks. The remote scenario achieved the most significant decrease in Energy Use Intensity (EUI), with a reduction of 46 % compared to the base case. Similarly, the implementation of flexible hours and remote working in scenarios resulted in a reduction of electric heating demand by up to 23 %, underscoring the potential of occupancy-based strategies in enhancing building energy efficiency. However, uncomfortable hours increased by 59 % in the 2-day remote working scenario compared to the base case, demonstrating the need to consider climate conditions when implementing remote work. The research offers valuable insights into the complex connections between flexible arrangements and energy efficiency, considering many elements such as occupancy schedule and use dynamics. This article offers a comprehensive analysis that may give architects, building managers, and policymakers valuable insights. This study contributes to the developing sustainable architecture by emphasizing the impact of dynamic occupancy on the energy performance of office buildings.

A novel framework reveals anthropogenic stressors of phosphorus polluted river-lake connection water system in Poyang lake basin of China

Poyang lake (PYL), as China's largest freshwater lake, has been suffering from increasing total phosphorus (TP) pollution associated with rapid basinal socio-economic development. However, anthropogenic phosphorus stressors were rarely examined in PYL basin due to its large-scale and complex river-lake connection water system, hampering phosphorus pollution control efforts. In this study, water pollution stress from multiple anthropogenic activities is quantitatively examined in PYL basin based on a newly developed framework coupling grey water footprint (GWF) analysis with the SPARROW model. Results show that the phosphorus source-sink process in PYL basin has been well simulated by SPARROW model quantifying an overall TP delivery rate of 0.39, with catchments closer to PYL showing higher delivery rate of phosphorus (up to over 0.8). The GWF analysis demonstrates that anthropogenic phosphorus sources have imposed much higher pollution stress on PYL than its inflowing rivers, with twelve catchments nearby PYL identified as critical source areas of TP contamination. Agricultural farming, livestock & poultry production, and urban household are recognized as the dominant anthropogenic stressors burdening water environment of PYL. Based on these, policy recommendations are provided for advancing control of the phosphorus pollution stressors. The methodology is effective in refined examination of water pollution sources, which is expected to be applied in other watersheds providing informative diagnosis of water issues especially in lakes.

Exploring the Father's Role in Determining Neonatal Birth Weight: A Narrative Review.

Birth weight, which exhibits variability across different populations, is influenced by a mix of genetic, environmental, and dietary factors originating from both the mother and father. Maternal characteristics, including age, socioeconomic status, prior pregnancies, weight, height, and weight increase throughout pregnancy, have a substantial influence on fetal growth and the health of the infant. On the other hand, the influence of paternal characteristics on the weight of newborns is still not fully comprehended in a consistent manner. Birth weight is an important factor that can help predict various maternal complications, such as the probability of having a C-section, experiencing postpartum hemorrhage or infections. It can also indicate future health challenges like asthma, cognitive impairment, and chronic diseases such as hypertension and diabetes. Nineteen publications were found through a thorough search of the Medline, PubMed, and Scopus databases, which provide insights into how paternal variables contribute to variations in birth weight. Significantly, the age of the father was found to be associated with higher chances of preterm birth and having a smaller size for gestational age in premature infants, while full-term children were more likely to have a larger size for gestational age. In addition, there is a constant correlation between the height of the father and the birth weight of the child. Taller dads are more likely to have babies with a higher birth weight and a lower likelihood of being small for gestational age (SGA). Although there were some discrepancies in the data about the weight and BMI of fathers, it was found that the height of fathers played a significant role in determining the size of the fetus and the weight of the newborn. While there may be differences in the conducted studies, these findings provide valuable insights into the complex connection between parental characteristics and fetal development. This data can be utilized to enhance clinical treatment strategies and enhance our comprehension of outcomes for neonates. Further homogeneous investigations are required to conclusively validate and build upon these findings.

‘Creating strong Sámi children’: teachers’ positioning of heritage language students

ABSTRACT This article presents an ethnographic study of Sámi heritage language education in public schools in a city in Norway. The Sámi people, the only recognised Indigenous people in Europe, are reclaiming their language and culture after intense assimilatory efforts by the Norwegian state. Based on ten weeks of fieldwork in Sámi heritage language (HL) education in an urban setting far from the Sámi core areas, the current article investigates how Sámi teachers and students negotiate subject positions in HL education based on Sámi culture, values, and traditional knowledge. The researcher observed lessons, wrote field notes, collected teaching materials, conducted interviews, and made video and audio recordings of classroom interactions. The analysis demonstrates how the teachers purposefully and iteratively attempted to position their students as Sámi and how the students responded to their teachers’ construction of a Sámi subject position. The findings suggest that HL teachers need to recognise and accommodate the complex and diverse connections that HL students have with their culture, language, and community, particularly in contexts of historical colonisation and assimilation. By making multiple subject positions available to students, teachers can contribute to a more inclusive and empowering learning environment that acknowledges the nuances of HL students’ subjectivities.

Coal Mine Slope Stability Analysis Using the Rock Mass Rating (RMR), Slope Mass Rating (SMR) Method, and Morgenstren-Price Limit Equilibrium for the Low Wall Pit Area Y PT. Bina Sarana Sukses, Lahat Regency, South Sumatra

Open pit mining has a complex connection to excavation and stockpiling operations, which can potentially induce slope instability. The analysis of slope stability is crucial to prevent slope failure, which has the potential to result in major losses. The study on slope stability was performed at the low wall pit Y area of PT. Bina Sarana Sukses site MAS in Lahat Regency. This research aimed to analyze the rock mass classifications, determine the safety factor values, and provide recommendations for mitigating landslide occurrences. The techniques employed in this study include the RMR and SMR methods for assessing the susceptibility of landslides, collectively with the Morgenstern-price limit equilibrium approach for estimating the stability of the slope. Based on the analysis of the rock mass rating (RMR) and slope mass rating (SMR), Block B2 exhibits a 20% likelihood of experiencing landslides, specifically due to block joint characteristics. On the other hand, Blocks B4 and B5 show a 40% potential for landslides, primarily associated with flat or wedge-type block joints. The force produced by friction under saturated conditions is comparatively lower than that observed under dry conditions. During the final design phase in 2022, it was observed that Blocks B4 and B5 exhibit critical and dangerous safety factors when saturated. Hence, the proposal has been suggested to enhance slope stability. Further, it is recommended to monitor the geotechnical piles periodically. We hope this research results as a valuable resource for evaluating and assessing slope stability, including artificial and natural slopes.

Stay safe, stay home? Majority world children, the COVID-19 pandemic, and (everyday) security politics

This article explores children in the majority world’s experiences of the stringent health security practices implemented in response to the COVID-19 pandemic. Drawing on original empirical research in five majority world countries, it examines children’s own accounts of their experiences of lockdowns and stay-at-home orders. Our analysis of the children’s narratives draws out the spatial, temporal, and affective dimensions of home-making under stay-at-home orders. In turn, we highlight complex and ambivalent connections between the notable and the mundane, between security and the everyday, and between home-making and world-building, and offer conclusions informed by majority world children on the ‘(important) banality of security and security politics’.

Fecal ARGs characterized progressive feralization of Przewalski's horses via re-introduction

Re-introduction of captive endangering or extinct animals to their native habitats holds profound ecological significance. But evaluating the feralization progress of re-introduced “wild” animals requires concise and quantitative indicator(s) to integrate traditional assessments on self-sustainability and reproduction. A fecal ARGs’ profiling was conducted for Przewalski’s horses, an extinct flagship herbivore, in Xinjiang, China from the Breeding Center (captive), Tianshan Wildlife Zoo (semi-captive), and Kalamaili Nature Reserve (re-introduction) with Mongolian wild asses serving as a reference in the shared Kalamaili range. Over 60 ARGs were quantified across 6 samples at each site for Przewalski’s horses while 46 ARGs for Mongolian wild asses. The re-introduced Przewalski’s horses had significant losses of fecal ARGs in sharing number and relative abundance in comparison to the captive ones. The re-introduced Przewalski’s horses had complex internal connections among the quantified fecal ARGs in expression potential (average relative abundance per quantified ARGs by antimicrobial category) and even more significant external connections with Mongolian wild asses than with captive horse. Overall, the re-introduction of Przewalski’s horses achieved notable and progressive success in feralization. Tetracyclines resistance genes (Tetra-RGs) alone, with full quantification frequency, could quantitatively characterized this achievement. Ratio of Tetra-RGs to aminoglycosides resistant genes (Amino-RGs) would differentiate the feralization progress with orders of magnitude, for the re-introduced Przewalski’s horses at 279 and the captive one at 11.7, against Mongolian wild asses at 0.86 in this study. The two ARGs-based indicators might be applicable to quantify feralization progress in re-introduction of other captive endangering or extinct animals with validations.

Exploring nonlinear dynamics in brain functionality through phase portraits and fuzzy recurrence plots.

Much of the complexity and diversity found in nature is driven by nonlinear phenomena, and this holds true for the brain. Nonlinear dynamics theory has been successfully utilized in explaining brain functions from a biophysics standpoint, and the field of statistical physics continues to make substantial progress in understanding brain connectivity and function. This study delves into complex brain functional connectivity using biophysical nonlinear dynamics approaches. We aim to uncover hidden information in high-dimensional and nonlinear neural signals, with the hope of providing a useful tool for analyzing information transitions in functionally complex networks. By utilizing phase portraits and fuzzy recurrence plots, we investigated the latent information in the functional connectivity of complex brain networks. Our numerical experiments, which include synthetic linear dynamics neural time series and a biophysically realistic neural mass model, showed that phase portraits and fuzzy recurrence plots are highly sensitive to changes in neural dynamics and can also be used to predict functional connectivity based on structural connectivity. Furthermore, the results showed that phase trajectories of neuronal activity encode low-dimensional dynamics, and the geometric properties of the limit-cycle attractor formed by the phase portraits can be used to explain the neurodynamics. Additionally, our results showed that the phase portrait and fuzzy recurrence plots can be used as functional connectivity descriptors, and both metrics were able to capture and explain nonlinear dynamics behavior during specific cognitive tasks. In conclusion, our findings suggest that phase portraits and fuzzy recurrence plots could be highly effective as functional connectivity descriptors, providing valuable insights into nonlinear dynamics in the brain.

S2069 The Interplay of Race, Obesity, and IBS: Understanding Complex Connections

Physical activity modifies the association between atherogenic index of plasma and prediabetes and diabetes: A cross-sectional analysis.

Although research has explored the association between atherogenic index of plasma (AIP) and prediabetes and diabetes, there is still not sufficient available evidence the role of physical activity (PA) in this relationship. Our purpose is to examine the complex connections between AIP, PA, and prediabetes and diabetes in a young and middle-aged population. This study included 2220 individuals from the general population, aged 20-60 years. AIP was calculated from the logarithm of the triglyceride (TG) to high-density lipoprotein cholesterol (HDL-C) ratio. PA was assessed depending to the American Heart Association (AHA) criteria and categorized into medium-high and low PA levels. We used binary logistic regression to explore associations and subsequently performed sensitivity and subgroup analyses. The 2220 participants had a mean age of 38 years, with a mean AIP of -0.1185, and a prediabetes and diabetes prevalence of 7.2%. After adjusting for auxiliary variables, AIP was positively correlated with prediabetes and diabetes (odds ratio [OR]: 3.447, 95% confidence interval [CI]: 1.829-6.497). In the low PA population, the prevalence of prediabetes and diabetes raised significantly with higher AIP (OR: 3.678, 95% CI: 1.819-7.434). This association was not meaningful in the medium to high PA population (OR: 1.925, 95% CI: 0.411-9.007). Joint and sensitivity analyze results also showed agreement. Restricted cubic spline identified a linear relationship between AIP and the prevalence of prediabetes and diabetes. Notably, the prevalence significantly increases when AIP values exceed -0.16 (p for linearity <0.05). The findings revealed heterogeneity across subgroups stratified by sex and age. PA may modify the link as regards AIP with prediabetes and diabetes in young and middle-aged populations. Adherence to PA prevents the adverse effects of abnormal glucose metabolism caused by dyslipidemia, particularly in women.

Comparing Machine Learning Regression Models for Early-Age Compressive Strength Prediction of Recycled Aggregate Concrete

A branch of artificial intelligence called machine learning is well-positioned as a prediction method that can take into consideration several influencing factors and complex inter-factor connections. Without being specifically trained to do so, these machine learning models have the ability to generalize, predict, and learn from data. Regression theory is a key topic in statistical modelling and machine learning. The main goal of this study is to compare the performance of several popular machine learning regression models for predicting the early-age compressive strength of concretes made from recycled concrete aggregates from a structure that demolished following the Sivrice-Elazig earthquake on January 24, 2020. Early-age concrete compressive strength is even more crucial due to factors like the fact that there are thousands of newly built structures in the aftermath of the earthquake, the quick manufacturing of these structures, and the completion of the project in the lowest amount of time. Determining the early-age concrete strength with high accuracy and in a useful manner is crucial for this reason. Seven different classical machine learning algorithms were employed in this study to achieve all of these goals. Early-age concrete compressive strength values were considered for 1 and 3 days. The relationship between the experimental results and the predicted outcomes of the employed algorithms was investigated, and a thorough comparison of these intelligent regression algorithms was conducted. Within the scope of sustainable development and circular economy goals, it is thought that this article will make significant contributions to the literature in terms of utilizing these waste materials and determining the early-age compressive strengths of the concretes produced with high accuracy.

Moderating Effect of IFRS Compliance on the Relationship between Ownership Structure and Financial Reporting Quality

This study investigates the moderating effect of International Financial Reporting Standards (IFRS) on the relationship between corporate governance, specifically ownership structure, and financial reporting quality in listed non-finance firms in Nigeria. Utilizing an ex-post facto research design, the study drew its data from 67 non-finance firms listed on the Nigerian Exchange Group over a ten-year period (2012-2021). The study employs purposive sampling and hierarchical regression analysis to explore the complex connection between IFRS adoption and ownership structures, revealing that IFRS plays a significant role in enhancing the quality of financial reporting. The findings indicate that while ownership concentration may weaken financial reporting quality in the absence of IFRS, the adoption of IFRS significantly moderates this effect, leading to improved transparency and reduced earnings manipulation. This study contributes to the existing literature by providing empirical evidence from a less developed market context, emphasizing the critical interaction between global accounting standards and corporate governance mechanisms. The study concludes that robust enforcement of IFRS compliance, combined with targeted capacity building for financial professionals, is essential to ensure high-quality financial reporting in Nigeria. Key implications include the need for enhanced regulatory oversight and collaboration between regulatory bodies and professional accounting organizations to foster consistent adherence to IFRS, thereby improving the reliability of financial statements and boosting investor confidence.
