High-precision 6D pose estimation for pick-and-place operations remains a critical problem for industrial robot arms in manufacturing. This study introduces an analytics-based solution for 6D pose estimation designed for a real-world industrial application: it enables the Staubli TX2-60L (manufactured by Stäubli International AG, Horgen, Switzerland) robot arm to pick up metal plates from various locations and place them into a precisely defined slot on a brake pad production line. The system uses a fixed eye-to-hand Intel RealSense D435 RGB-D camera (manufactured by Intel Corporation, Santa Clara, California, USA) to capture color and depth data. A robust software infrastructure developed in LabVIEW (ver.2019) integrated with the NI Vision (ver.2019) library processes the images through a series of steps, including particle filtering, equalization, and pattern matching, to determine the X-Y positions and Z-axis rotation of the object. The Z-position of the object is calculated from the camera’s intensity data, while the remaining X-Y rotation angles are determined using the angle-of-inclination analytics method. It is experimentally verified that the proposed analytical solution outperforms the hybrid-based method (YOLO-v8 combined with PnP/RANSAC algorithms). Experimental results across four distinct picking scenarios demonstrate the proposed solution’s superior accuracy, with position errors under 2 mm, orientation errors below 1°, and a perfect success rate in pick-and-place tasks.

The present study adopts the social constructivism theory and consumer decision-making process model with the aim of examining the social identity that consumers build through the purchase of electric vehicles (EVs) in line with their income, age, gender, and education. The study’s findings indicate that this social identity, shaped by income, age, gender and education, exerts a significant influence on consumer decision-making behavior. This identity is shaped not only by the make and model of EVs chosen, but also by their preferences for vehicle performance and technical features. The adoption of EVs by consumers is driven by dual objectives: the fulfilment of practical needs and the shaping of social identities in social interactions that correspond to their income, age, gender, and education. The study’s findings are of significant value in understanding the social identity aspirations of consumers in the electric vehicle consumer market, and provide a theoretical foundation for future electric vehicle companies to create products and corporate cultures that meet their target customers, thereby effectively promoting the popularization of electric vehicles.

In a global context characterized by budgetary pressures, aging populations, and accelerated economic transitions, the capacity of countries to mobilize stable and sustainable tax revenues represents a crucial pillar for maintaining macroeconomic stability and social cohesion. This research investigated the determinants of total tax revenues in the developed economies of the G7 group (Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States) during the period 2000–2022, employing both static and dynamic panel econometric approaches. The estimated model considered total tax revenues as the dependent variable, while the explanatory variables encompassed the main categories of government revenues: direct taxes (personal and corporate income), indirect taxes (consumption, trade, and other taxes), social contributions, grants, other non-tax revenues, and institutional quality indicators (regulatory quality and control of corruption). The empirical findings revealed that all tax components analyzed exert a positive and significant influence on total tax revenues, with particularly strong effects observed for consumption taxes, social contributions, and personal income taxes. Based on these results, the study provides policy recommendations aimed at diversifying revenue sources, balancing direct and indirect taxation, and broadening the tax base equitably. The study advances the literature on international taxation by offering an integrated and comparative analysis of the revenue structures in advanced economies, while also identifying relevant pathways for sustainable tax reforms in a dynamic global environment.

This study investigated how corporate maturity—measured through firm age and lifecycle stage—moderates the value relevance of Environmental, Social, and Governance (ESG) disclosures in a frontier market context, using Bangladesh as a case study. Drawing on panel data from 2011–2012 to 2023–2024 for 86 publicly listed non-financial firms, the study employed a modified Ohlson valuation framework, panel regression analysis, and multiple robustness techniques (2SLS, PSM). ESG disclosure was measured using a researcher-developed index aligned with international reporting standards (GRI, SASB, TCFD, UN SDGs). ESG disclosures are positively associated with firm value, but this relationship is significantly moderated by corporate maturity. Younger firms exhibit a stronger valuation effect from ESG transparency, driven by higher signaling and legitimacy needs. In contrast, mature firms experience a diminished marginal benefit, reflecting routine compliance rather than strategic differentiation. These findings challenge the uniform application of ESG assessment models and suggest the need for lifecycle-adjusted disclosure ratings, particularly in nascent regulatory environments like Bangladesh. Investors and regulators should tailor ESG evaluation criteria by firm age and industry sustainability exposure. Younger firms, often overlooked, may carry outsized ESG signaling value in emerging markets. Enhancing ESG transparency among younger firms can foster greater stakeholder trust, support inclusive growth, and strengthen social accountability in emerging economies. This study contributes to the ESG literature by introducing corporate maturity as a key moderating variable in value relevance analysis. It provides new empirical insights from a developing economy and proposes lifecycle-based adaptations to global ESG rating methodologies. Full article

Background and Objectives: Air pollutants have been shown to affect hypertensive disorders and placental hypoxia due to vasoconstriction, inflammation, and oxidative stress. The objective of this study was to evaluate whether high levels of maternal exposure to heavy metals during the second trimester of pregnancy are associated with an increased risk of preeclampsia and eclampsia, using national health insurance claim data from South Korea. Methods: Data on mothers and their newborns from 2016 to 2020, provided by the National Health Insurance Service, were used (n = 1,274,671). Exposure data for ambient air pollutants (PM2.5, CO, SO₂, NO₂, and O₃) and heavy metals (Pb, Cd, Cr, Cu, Mn, Fe, Ni, and As) during the second trimester of pregnancy were retrieved from the Korea Environment Corporation. Atmospheric condition data based on the mother’s registration area were matched. A logistic regression model was adjusted for maternal age, infant sex, season of conception, and household income. Results: In total, 16,920 cases of preeclampsia and 592 cases of eclampsia were identified. In the multivariate model, copper exposure remained significantly associated with an increased risk of preeclampsia (odds ratio: 1.011; 95% confidence interval: 1.001–1.023), and higher ozone exposure during pregnancy was associated with an elevated risk of eclampsia. Conclusions: Increased copper exposure during the second trimester of pregnancy was associated with a high incidence of preeclampsia. Full article

The objective of the study is to demonstrate how cognitive chief executive officers (CEOs) influence corporate social and environmental performance under the moderating impact of innovation, supervisors and cash holdings. Significantly, we have formulated cognitive CEOs using data envelope analysis while considering the specific attributes of the incumbent CEO (by considering the age, tenure, goodwill, education and tacit knowledge of CEOs). The research approach aims to elucidate that cognitive CEOs strongly invigorate social and environmental performance. However, the moderating role of corporate innovation weakens this connection, whereas the moderating role of supervisors invigorates this relationship. In contrast, cash hoarding deters social and environmental performance through its moderating effectiveness. Conclusively, theoretical contribution illuminates the stakeholder theory frame of reference while emphasizing the identification of corporate social and environmental performance. Specifically, the role of cognitive CEOs has been signified as a promoter of such strategies, which indicate their orientation toward social responsibility. Empirical underpinnings illustrate the impact of corporate innovation, supervisors and cash holdings, which asymmetrically influence social and environmental performance. The recommendations of the research results refer to the characterization of the optimal attributes of cognitive CEOs that are essential to enhance social and environmental performance. Full article

Enterprise digital transformation has emerged as a key strategy for enhancing innovation capacity in the age of the digital economy. This article aims to analyze the influence mechanism of digital transformation on corporate innovation and evaluate the mediating function of corporate innovation and cooperative cultures between digital transformation and corporate innovation capability. This work builds a panel data model based on data from Chinese A-share listed businesses from 2012 to 2021, empirically analyzes it using the Tobit model and the fixed effects model with instrumental variables technique, and uses the mediation effect test to uncover the course of action. According to the report, digital transformation significantly enhances creativity capability; second, corporate collaborative and innovation cultures mediate the relationship between digital transformation and innovation outcomes, and cultural capital becomes a crucial link; and third, the influence of digital transformation on corporate innovation capability is greater in state-owned enterprises, non-monopoly industries, and high-tech industries. According to the study, businesses should work to realize the dual-wheel drive of “technological investment + cultural cultivation” and establish an open and collaborative innovation ecosystem, while the government should intensify the development of digital infrastructure, enhance the supporting system, encourage cultural construction and talent supply, and create an environment that supports the synergistic development of digitization and innovation.

Background/Objectives: Pancreatic neoplasms, including adenocarcinoma, pancreatic neuroendocrine tumors (pNETs), intraductal papillary mucinous neoplasms (IPMNs), and high-grade cystic lesions, often require surgical resection as a form of curative treatment. However, comorbidities and high-risk features may preclude surgery. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) has emerged as a minimally invasive alternative with proven cytoreductive efficacy in solid tumors. This case series evaluates the safety and efficacy of EUS-RFA in patients with various unresectable, non-metastatic pancreatic neoplasms. Methods: A retrospective review was conducted on eight patients who underwent EUS-RFA at our institutions between July 2021 and February 2025. All patients were deemed unsuitable surgical candidates due to comorbidities such as advanced age, cardiovascular disease, renal insufficiency, and COPD or due to patient resistance to surgical intervention. EUS-RFA was performed using a 19-gauge RFA needle (Taewoong Corporation). Follow-up imaging was conducted 3 to 6 months after the completion of RFA treatment. Results: All eight patients demonstrated a good to excellent response in terms of tumor size reduction. The most notable response was observed in a patient with pNET, resulting in complete resolution from 15.6 × 12.0 mm to 0.0 × 0.0 mm after two RFA treatments. Other neoplasms, including pancreatic adenocarcinoma and intraductal papillary mucinous neoplasms (IPMNs), also demonstrated significant reductions. Mild post-procedure complications, including pancreatitis and abdominal pain, were noted in three cases. Conclusions: EUS-RFA is a promising alternative for managing unresectable pancreatic neoplasms in high-risk patients. Our findings support its use across various tumor types with favorable outcomes and minimal complications, reinforcing its role in expanding therapeutic options beyond surgery. Full article

Background and Objectives: Globally, there is a demographic transition toward an increase in the number of older adults, and with it, the comorbidities associated with aging. This requires healthcare providers to understand which variables can affect functional independence for performing activities of daily living. The general objective of this study was to determine the predictive effect of left and right handgrip strength, depression, mild to moderate dementia, and cognitive function on functional independence in older adults. Materials and Methods: This study featured a predictive cross-sectional design with n = 84 older adults with some level of physical independence; older adults with completely limited physical independence and those with severe dementia were excluded. To assess depression, the Geriatric Depression Scale was used; for dementia, the Hachinski Ischemic Scale was used; for cognitive impairment, the Folstein version of the MMSE was used; for functional independence, the Barthel Index was used; for handgrip, a 90-kg Dynatron^® professional hydraulic dynamometer (UT 84121) Number Series. 11010141, from the Dynatronics Corporation located in Salt Lake City, Utah USA, was used. Results: In total, 58.8% of the participants were female, with a mean age of 84.89 ± 7.095, with ranges from 68 to 102 years. Multiple regression analysis showed that the level of cognition, left-hand grip strength, and a low level of depression are strong predictors of independence in activities of daily living in the elderly, with an explained variance of R² = 0.34. Conclusions: Cognitive function, left-hand grip strength, and depression significantly predict the independence of older adults. Studies with larger sample sizes are recommended to confirm the veracity of the results and to design methodologically rigorous interventions that include psychological aspects such as cognitive stimulation, promoting physical activity, and addressing depressive problems to improve the functional independence of older adults.

Background/Objectives: The COVID-19 pandemic has been associated with significant increases in mental-health-related concerns in adolescents, including eating disorders. Disparities in screening, diagnosis, and treatment impact adolescents with eating disorders. This study aimed to describe the patterns in the prevalence and the associations between eating disorder diagnoses and demographic factors in adolescent patients since the start of the COVID-19 pandemic. Methods: We performed a retrospective cohort study examining adolescent patients (aged 12 to 21) with an eating disorder (ED) diagnosis documented between January 2019 and July 2023 using Epic Systems Corporation’s Cosmos, a de-identified dataset aggregated from electronic health record (EHR) data. We examined the differences in demographic factors by utilizing chi-square and Kruskal–Wallis rank sum tests. Results: A total of 82,435 distinct adolescent and young adult patients with eating disorder diagnoses were included in the analytical dataset. The overall prevalence of EDs has increased since 2019. The median age of patients with an ED decreased between 2019 and 2023. There was a decrease in other eating disorder diagnoses and an increase in avoidant-restrictive food intake disorder (ARFID) during the study period. There was a decrease in the proportion of individuals who identified as White and an increase in the proportion of adolescents from historically minoritized racial and ethnic groups (i.e., African American or Black and Hispanic). There was also an increase, during this study period, in the proportion of adolescents with an ED diagnosis who were from more socially vulnerable communities. Conclusions: Our study describes the changes in the prevalence of sociodemographic factors in adolescent patients with EDs since the start of the COVID-19 pandemic. Further studies should address screening, diagnostic, and treatment barriers for EDs in historically underserved communities. Full article

In emerging economies, where the legislative and economic landscapes may significantly differ from those of advanced economies, accrual-based earnings management (AEM) is especially problematic for financial disclosure and investor trust. This paper conducts a systematic literature review and a bibliometric analysis to evaluate the incentives for AEM in developing countries and to understand the evolution of the AEM domain within emerging countries. For this purpose, 312 journal articles from ResearchGate, Google Scholar, ScienceDirect, Google, and Scopus, covering the period from 2000 to 2024, were reviewed under various thematic areas. The findings highlighted multiple significant motivators for AEM within developing markets, encompassing financial distress, loss avoidance, profitability pressures, high leverage, weak corporate governance structures and processes, diverse ownership structures (such as concentrated ownership, family ownership, institutional ownership, government ownership, and insider ownership), market performance indicators, political ties, weak regulatory systems, as well as factors such as executive compensation, tenure, career retention, agency issues, investor expectations, audit quality, economic crises, and firm-specific characteristics like size, reputation, and age. This research contributes to existing knowledge by examining the motivations behind AEM in emerging economies, underscoring the need for tailored regulatory frameworks and strong governance structures and processes to address the unique challenges developing nations face. For regulators and policymakers, these findings emphasize the need for robust regulatory frameworks, more stringent auditing protocols, and improved corporate governance structures to discourage business executives from engaging in AEM practices.

Methods. Through the lens of childhood trauma theory, a qualitative phenomenological study was conducted using purposive and snowball sampling methods to gain a deeper understanding of the experiences of former students with corporal punishment and how those experiences have shaped their academic and psychological outcomes. Interviews were conducted via Zoom with 19 men and women of different ages and races who attended schools in Mississippi. Results/Conclusions. The study revealed that parents and school personnel collaborated to punish the student corporally both on campus and at home. Related, beaten students did not share their punishment with their parents/caregivers, and if their families did find out, they received another beating at home. There was a general lack of consistency in how and who administered corporal punishment. In addition to the well-documented ways that corporal punishment is administered in school, we also found that students were made to hold painful positions or perform painful tasks. There were also peer effects of trauma, with students experiencing fear or anger following a friend or classmate being beaten in front of them. Race was an influence if the abused students felt that their punishment was racist, with Black American participants feeling there were racial undertones regardless of the perpetrator’s race. The study’s findings align with those of previously conducted research, but also extend them and can be used to create policy to allow schools to address trauma and create instructional practices that eliminate the fear and racial disparities that have been proven to exist in schools with corporal punishment.

This study aims to investigate the impact of board size on environmental, social, and governance (ESG) controversies using data from Chinese-listed companies during 2007–2022. In addition, we explore the moderating effects of female participation on corporate boards, board age, financing constraints, and internal control. ESG controversies are measured by an ESG controversies score from the LSEG Workspace, and fixed effects models are used to perform the analysis. The results show that larger boards can lead to more ESG controversies in China. This impact is greater in non-manufacturing, heavily polluted, and non-high-tech industries, in state-owned enterprises, eastern regions, and non-foreign-funded companies. Additionally, women on boards and internal control weaken the impact of board size on ESG controversies, while financing constraints strengthen this impact. The moderating effect of board age is not significant. The findings can help Chinese-listed companies improve their ESG performance and achieve sustainable development through strengthening corporate governance. Full article

Background. Poor posture is a common musculoskeletal concern in children and adolescents and may lead to spinal discomfort and long-term structural issues. While excess weight has been linked to altered sagittal alignment, the impact of sports participation on spinal posture remains unclear. This study aimed to investigate the associations between weight status, sports participation, and sagittal spinal alignment in a pediatric population. Methods. This cross-sectional study was conducted within the “Ferrari Formula Benessere” corporate wellness program and included 698 children aged 5 to 16 years. Sagittal Index (SI) was measured using a standardized plumb line technique. Body mass index (BMI) was calculated and classified according to the WHO growth standards. Sports participation was self-reported and grouped into five categories: sedentary, skill-based, power-based, mixed, and endurance sports. Results. Age was the only significant independent predictor of the SI (β = 2.45, p < 0.001), with older children exhibiting higher SI values. Although a weak correlation was observed between BMI and SI (Spearman’s r = 0.24, p < 0.001), BMI was not a significant predictor when controlling for age. No significant differences in the SI were found between active and non-active children. Among sport disciplines, the SI was lowest in power-based sports (56.7 ± 22.3 mm) and higher in endurance (62.7 ± 24.4 mm), mixed (64.5 ± 23.2 mm), skill-based (61.1 ± 22.0 mm), and non-sport (64.2 ± 24.0 mm) groups, although these differences did not reach statistical significance (ANOVA p = 0.224). Conclusions. Age appears to be the primary factor associated with sagittal spinal alignment in children, while BMI and general sports participation showed no independent effect. Although some differences emerged between sport types, these findings were not statistically significant and should be interpreted with caution. These findings underscore the need for sport-specific, longitudinal research using objective posture assessment methods. Full article

Climate change disinformation has emerged as a substantial issue in the internet age, affecting public perceptions, policy response, and climate actions. This study, grounded on the theoretical frameworks of social epistemology, Habermas’s theory of communicative action, post-truth, and Foucault’s theory of power-knowledge, examines the effect of digital infrastructures, ideological forces, and epistemic power dynamics on climate change disinformation. The meta-synthesis approach in the study reveals the mechanics of climate change disinformation on social media, the erosion of epistemic welfare influenced by post-truth dynamics, and the ideological and algorithmic amplification of disinformation, shedding light on climate change misinformation as well. The findings show that climate change disinformation represents not only a collection of false claims but also a broader epistemic issue sustained by digital environments, power structures, and fossil corporations. Right-wing populist movements, corporate interests, and algorithmic recommendation systems substantially enhance climate skepticism, intensifying political differences and public distrust in scientific authority. The study highlights the necessity of addressing climate change disinformation through improved scientific communication, algorithmic openness, and digital literacy initiatives. Resolving this conundrum requires systemic activities that go beyond fact-checking, emphasizing epistemic justice and legal reforms. Full article
