The rapid proliferation of artificial intelligence (AI) systems across high-stakes domains—with global AI adoption accelerating since 2023—has created an urgent need to identify which AI challenges and issues are materializing into real-world harms so that policymakers can develop targeted regulations, organizations can implement effective risk management, and accountability mechanisms can address actual rather than speculative problems. Public concern has risen sharply: 52% of Americans now feel more concerned than excited about AI (up from 38% in 2022), and 80% believe government should maintain AI safety rules even if development slows. Yet existing approaches exhibit critical limitations that impede evidence-based governance. Ethics frameworks, while establishing normative principles across 84+ published guidelines, remain aspirational rather than empirical. Survey-based studies capture perceptions from over 48,000 respondents globally but measure expectations rather than documented harms. Incident databases catalog over 1200 AI failures but depend on media coverage, systematically overrepresenting high-profile cases while underrepresenting routine organizational problems. This study addresses this gap by analyzing 347 AI-related U.S. litigation cases using machine learning text analytics, providing empirical evidence of AI problems that have crossed the threshold from abstract concern into documented legal conflict. Employing Latent Dirichlet Allocation (LDA) and Non-negative Matrix Factorization (NMF) topic modeling with coherence validation (NMF achieving 0.276 NPMI vs. LDA’s 0.164), the analysis identifies nine distinct AI issue areas with specific case distributions: cybersecurity vulnerabilities and data breaches (116 cases, 33.4%), intellectual property and AI ownership (61 cases, 17.6%), AI misrepresentation and inflated claims (59 cases, 17.0%), criminal justice and algorithmic due process (37 cases, 10.7%), employment automation (33 cases, 9.5%), privacy and surveillance (31 cases, 8.9%), platform accountability (21 cases, 6.1%), algorithmic bias (19 cases, 5.5%), and government AI deployment (6 cases, 1.7%). The findings reveal a systematic mismatch between AI ethics discourse—which emphasizes fairness and transparency—and litigation patterns, where data security (33.4%) and intellectual property (17.6%) dominate while algorithmic bias comprises only 5.5% of cases. Most disputes are addressed through existing legal frameworks (First Amendment, Lanham Act, FOIA, Title VII) rather than AI-specific regulation, underscoring the urgent need for governance mechanisms aligned with empirically documented AI challenges.

This study examines the relationship between greenwashing and firm risk among listed Australian firms from 2014 to 2023. We construct a firm-level greenwashing score as the residual based on regressions of composite ESG on Scope 1–2 CO₂ emissions; positive residuals indicate overstated sustainability relative to emissions. Using realized volatility as a measure of firm risk and applying the Generalized Method of Moments (GMM) regression framework, we uncover three key findings. First, contemporaneous greenwashing significantly lowers volatility, which is consistent with legitimacy and signalling theory, as overstated ESG credentials create a temporary perception of stability. Second, the risk-reducing effect is strongest with a one-period lag, likely reflecting delayed ESG and emissions reporting cycles and investor reaction times. Third, by the two-period lag, the effect reduces in magnitude, suggesting that markets eventually recognize the misalignment between ESG claims and environmental performance. Robustness checks with the E-pillar confirm these dynamics. Additional tests excluding the COVID-19 period (2020 and 2021) reveal that the risk-mitigating effects of greenwashing are even stronger during normal market conditions, implying that pandemic-related volatility may have muted the signalling power of ESG narratives. While firm fundamentals (e.g., book-to-market) explain part of risk variation, greenwashing-driven effects are economically meaningful yet short-lived. The findings underscore that greenwashing offers only temporary risk mitigation; as transparency improves and regulatory enforcement strengthens, firms relying on inflated ESG narratives face diminishing benefits and potential long-term risk penalties.

Sexual and romantic partners tend to match on various dimensions of mate value including physical attractiveness. Men may be motivated to inflate their self-perceived physical attractiveness to justify pursuing highly attractive women. In the present research, heterosexual men (N = 180) received random assignment to a two-way between-participants factorial design that tested the effects of a woman’s physical attractiveness (low vs. high) and the recipient of her ambiguous sexual behavior (the participant himself or another man) on men’s ratings of her sexual intent. Participants rated that attractive women had greater sexual intent compared to unattractive women, but only when the participant himself was the recipient of women’s behavior. Men’s self-perceived physical attractiveness did not vary as a function of the woman’s physical attractiveness except when another man was the recipient of a physically attractive woman’s behavior, which reduced men’s perceptions of their physical attractiveness. Findings suggested that men’s self-perceptions and women’s appearance may bias men’s sexual judgment. Full article

The measurement of national well-being has become central to both academic and policy debates, particularly within the framework of sustainable development. In this context, this study investigates the relationship between macroeconomic conditions and subjective well-being in Portugal. Using annual data from 2004 to 2022, we explore the effects of GDP per capita, unemployment, and inflation on the Global Well-Being Index (GWBI). Employing ordinary least squares (OLS) regression, the results indicate a significant positive relationship between GDP per capita and subjective well-being, while inflation is negatively associated. Contrary to expectations, the unemployment rate showed a positive and significant association with the GWBI. This counterintuitive result may reflect institutional buffering effects, such as social safety nets, strong family structures, or lagged responses in perceptions of well-being. Similar patterns were observed in other southern European countries with strong informal social support systems. These findings contribute to a deeper understanding of how economic indicators relate to perceived well-being, particularly in the context of a southern European country. The study offers relevant insights for public policy, including the alignment of macroeconomic management with the Sustainable Development Goals (SDGs), especially SDG 3 (Good Health and Well-being) and SDG 8 (Decent Work and Economic Growth).

The polemics of idol worship in John Capgrave’s Life of Saint Katherine of Alexandria have been interpreted by previous scholars as either the author’s engagement with the Lollard image controversy or a political critique of Henry VI. This essay, however, shifts the focus from Katherine and her iconoclasm to the concept of divine iconoclasm, defined here not only as the divinely sanctioned or divinely motivated destruction of religious images but also as God’s direct intervention to dismantle false representations and correct human perceptions of the divine. It further argues that Capgrave’s Life redefines sacred space as primarily constructed through light, emphasizing its immateriality and exposing the saint’s physical limitations. In these scenarios, divine iconoclasm emerges as a constructive force that resolves the tension between the secular and the sacred. Moreover, Christ’s celestial manipulation of the vision of sacred space and the relationship between body and space—encouraging confidence while discouraging self-inflation—serves as a model for how a monarch should inspire both love and fear. In this way, Capgrave’s Mirrors for Princes is embedded within his hagiography, where the image debate features prominently, addressing the heated political and theological controversies of his time. By combining these elements, the essay bridges two strands of criticism that have previously treated the political and theological dimensions of the text separately. Full article

Inflation remained quiescent for several decades and then surged in 2021 and 2022. Inflation subsequently fell in 2023 and 2024. This paper investigates how the rise and fall in inflation after 2019 affected the U.S. stock market. To do this, it estimates a fully specified multi-factor model that measures the exposure of 54 assets to inflation, monetary policy, and other macroeconomic variables over the 1994 to 2019 period. This paper then uses the inflation betas to investigate how investors’ perceptions of inflation changed between 2020 and 2024. The results indicate that concerns about inflation roiled the stock market over this period. The Fed’s anti-inflationary policies whipsawed markets even more. These findings highlight the dangers that arise when monetary policy allows inflation to accelerate. Full article

As part of its plan to transition to an energy secure and environmentally sustainable future, Canada has had a national carbon pricing system since 2019. When first introduced, the $20 (‘$’ refer to Canadian dollars (CAD) in this paper) per tonne price was widely accepted by most Canadians and seen as a way of helping Canada meet its emissions reduction pledges made at the 2015 United Nations Climate Change Conference (COP 21) in Paris. The Canadian system is novel in that it both charges consumers for their emissions and reimburses them for their expected emissions; this is intended to raise awareness of their emissions and encourage those who can afford to opt for lower-emissions energy services to do so. By 2023, the combination of the carbon price reaching $65 per tonne and the post-pandemic economic slowdown was seized on by numerous politicians as a way of pushing back against the carbon pricing system, with most demanding the entire system be scrapped. The debate intensified in late 2023 and into 2024, when the federal government removed the carbon tax on home heating oil because the reimbursement was insufficient to cover the cost of the tax. In this paper, we consider the recent actions of two Canadian provinces, Saskatchewan and Nova Scotia, embroiled in the federal carbon pricing system debate due to the removal of the carbon tax on fuel oil for space heating. The objective of this paper is to identify how some of the reasons, including global post-pandemic inflation and other challenges facing Canadians, such as those cited in third-party polls, have contributed to a rise in the system’s unpopularity. Our method estimates and compares the impacts of the carbon tax on the household energy services for space and water heating, lighting and appliances, and private (i.e., household) transportation for different types of housing (apartment, single-attached, and single-detached) and number of occupants (two, three, and four) in Saskatchewan and Nova Scotia. The results of this work show that while Saskatchewan households have higher energy intensities than those in Nova Scotia, the impact of the carbon tax on Nova Scotians using fuel oil for heating was greater than in Saskatchewan. In Saskatchewan and Nova Scotia, natural gas and electricity, respectively, are used for heating. This paper concludes with a summary of our findings and potential options for improving perceptions of the system. Full article

Background: Sugar-sweetened beverages (SSBs) account for a significant proportion of sugar in the diet of children and are directly associated with obesity in this group. While there have been many studies on adolescent SSB consumption, few studies have examined the predictors of SSB consumption in primary-school-aged children. The aim of this study was to understand the degree to which a child’s consumption across a range of beverages is influenced by their own attitudes and by their parents’ attitudes and parents’ consumption behaviours. Methods: A survey of 1611 Australian parent–child dyads asked children (aged 4–11) and their parents to rate a variety of drinks in terms of healthiness, taste, and cost and indicate the amount of these drinks consumed in a typical week. Zero-inflated regression analyses were conducted to identify the strength of association between children’s weekly beverage consumption, their perceptions of each beverage, their parents’ perceptions, and their parents’ weekly beverage consumption. Results: Parental consumption of a specific beverage was the strongest predictor of child consumption of that beverage, more so than the children’s perceptions of the beverage. Conclusions: These findings provide insights for developing parent and child education programmes to reduce SSB consumption. Full article

This work aims at understanding the level of financial literacy in Portugal, identifying the determinants of financial literacy in the Portuguese population, taking as an example certain sociodemographic factors such as gender and age. The aim is to understand whether there is a high level of adherence to financial literacy programs and initiatives, as well as the impact of financial knowledge variables on the financial literacy of the Portuguese population. The methodology used was quantitative and based on a questionnaire survey. The sample consisted of 600 individuals, all over 18 years old. It was concluded that individuals in the 26 to 35 age group had the best knowledge and that this sample showed better knowledge of interest rates compared to inflation and risk. The exploratory factor analysis shows five factors that determine the financial literacy of the Portuguese population and the way they manage their finances, which are (1) the perception of their current financial situation; (2) planning and controlling personal finances; (3) the perception of risky financial assets; (4) the perception of risk-free financial assets; and (5) savings. This research contributes to expanding scientific understanding in the field of financial literacy and offering support to the review of financial education policies by formulators, aiming to develop tools that help improve the financial behavior of the Portuguese population.

The paper departs from the observation that the role of migrant organisations (MOs) in Germany has changed significantly since the strong influx of refugees in 2015/16. As a result of this specific historical situation, it seems that MOs were able to strengthen their position as important civil society and integration policy actors and reduce reservations about them. While there has been growing attention on MOs’ civic and social contributions, both in public and academic debates, this article also highlights the risks of failure and inflated expectations and the often rather fragile structures of MOs. Thus, the article aims to broaden the view on MOs by focusing on aspects which have been neglected in the course of recent public and academic interest and rather optimistic perceptions. The methodological approach is one of “embedded research”: the author has been a senior executive of one of the largest German MOs for six years and, at the same time, a migration researcher for many years. From this special inside/outside view, an ambivalent picture emerges: despite a significantly greater appreciation of the achievements of MOs and much verbal recognition, there is a clear lack of the necessary material/structural support, jeopardising the sustainability and viability of many MOs.

Consumers’ perception plays a central role in tackling food waste at the final consumption stage, specifically among university students. In Europe, it is estimated that 47 to 67 Mt of food waste is generated at the household level or at food service consumption, including university canteens. The present cross-country research, through an online-based questionnaire among university students, investigates students’ perception on food waste by distinguishing among two different categories: on the one side, students living with their family; on the other side, students living without their family. Further, the research distinguishes among students eating at university canteens, students preparing food at home, students purchasing take-away foods and students coming back home to eat. The study compares university students’ perception on food waste in Italy and in Poland, with the overarching purpose of shaping sustainable pathways and defining educational interventions to enhance students’ perception and awareness on food waste. Data are analyzed according to the Mann–Whitney U test and the Kruskal–Wallis test. Age is a pivotal factor and suggests a generational gap in awareness and attitude toward food waste, whereas sex significantly affects food waste perception in Poland but not in Italy, suggesting a more homogeneous perception across sexes. The research highlights the impacts that socio-economic and environmental crises (e.g., climate change, the Russia–Ukraine conflict, high inflation rates) have on food waste perception in Poland, which is closer to that of Russia and Ukraine compared to that of Italy, and provides academics, practitioners and public authorities with practical and theoretical insights toward food waste minimization.

Circulating tumor DNA (ctDNA) monitoring, while sufficiently advanced to reflect tumor evolution in real time and inform cancer diagnosis, treatment, and prognosis, mainly relies on DNA that originates from cell death via apoptosis or necrosis. In solid tumors, chemotherapy and immune infiltration can induce spatially variable rates of cell death, with the potential to bias and distort the clonal composition of ctDNA. Using a stochastic evolutionary model of boundary-driven growth, we study how elevated cell death on the edge of a tumor can simultaneously impact driver mutation accumulation and the representation of tumor clones and mutation detectability in ctDNA. We describe conditions in which invasive clones are over-represented in ctDNA, clonal diversity can appear elevated in the blood, and spatial bias in shedding can inflate subclonal variant allele frequencies (VAFs). Additionally, we find that tumors that are mostly quiescent can display similar biases but are far less detectable, and the extent of perceptible spatial bias strongly depends on sequence detection limits. Overall, we show that spatially structured shedding might cause liquid biopsies to provide highly biased profiles of tumor state. While this may enable more sensitive detection of expanding clones, it could also increase the risk of targeting a subclonal variant for treatment. Our results indicate that the effects and clinical consequences of spatially variable cell death on ctDNA composition present an important area for future work. Full article

Abnormal visceral perception and motor function are often observed in patients with fecal incontinence, evacuation disorders and irritable bowel syndrome. The international anorectal physiology working group has proposed a standardization for anorectal function assessment, where rectal sensitivity testing is performed using an elastic balloon attached to a high-resolution anorectal manometry (HRAM) catheter. Rectal compliance, another component of rectal function evaluation, is a pressure–volume relationship that refers to the rectum’s ability to stretch and expand as it receives and holds fecal matter. There are no data available regarding the possibility of compliance testing using HRAM, although this is theoretically possible by correcting for the elastic balloon’s intrinsic properties. The gold standard for measurement of visceral sensitivity and compliance is the rectal barostat, according to the procedure described by the European COST action GENIEUR group. Data on the agreement between the two different procedures are scarce. Hence, we performed a comparative study of the HRAM and barostat investigations in 26 healthy individuals. We hypothesized that by inflating the balloon before the examination, rectal compliance can be measured with HRAM investigations, and we examined correlations and levels of agreement between the methods. Our results demonstrate that assessing rectal compliance with HRAM is technically possible; however, a strong correlation with the rectal barostat was only observed at the maximum tolerable volume (Spearman’s rho = 0.7, p = 0.02). We only found moderate correlations (Spearman’s rho = 0.562, p = 0.019) for compliance according to the barostat methodology and for rectal sensibility testing (Spearman’s rho = 0.57, p = 0.03 for maximum tolerable volume). Bland–Altman plots showed poor levels of agreement between the methods. We conclude that HRAM and the rectal barostat cannot be used interchangeably for compliance or sensitivity assessments. We suggest the development of a non-elastic balloon with a fixed size and shape to assess rectal sensory function and compliance in HRAM testing. Full article

There has been a wide belief that real estate is a source of good investment portfolios because it has a hedge against inflation. Considering this notion, the present research examined the dynamics of the inflation-hedging capabilities of real estate investment in Nigeria’s three foremost property markets, Abuja (Maitama and Central Business District), Lagos (Lekki and Victoria Island), and Port Harcourt (Rumu Ibekwe and Aba Road). To achieve this aim, this study was carried out by exploring the returns on different types of commercial properties in the chosen location and investigating the effect of inflation on such returns in order to come up with the hedging capabilities of the assets. Out of the four property prime locations in Nigeria’s market, these selected study sites were purposely selected for investigation because they comprise the most desirable and preferred properties regarding location, standards, aesthetics, and value. From the data collected, a mean return, coefficient of variation, and ordinary least square regression analysis were completed. In terms of the coefficient of variation (CV), the findings reveal that the duplex in Port Harcourt exhibits the most performed investment, with a value of 0.33, compared to other locations. However, in terms of the expected return (ER), the duplex outperformed other property types in the different locations, with a return of 39.56%. Results also show that inflation has an adverse effect on the returns of the office space for the three locations considered, with the expected returns below 1%. The block of flats in Abuja has a complete defence against the three components of inflation, with a coefficient beta of 0.5633, 0.6586, and 0.8440, respectively. Thus, investors should consider inflation and other investment attributes when making decisions among arrays of investments. This will help guard against the widespread perception that real estate has a hedge against inflation. This paper adds to the existing literature on inflation hedging by investigating the effect of inflation on the real estate investment returns of commercial properties. Full article

In this review, we examine the impact of the Inflation Reduction Act (IRA) of 2022 on pharmaceutical drugs in the United States, drawing on a diverse range of sources to understand the perceptions of multiple stakeholders and professionals. Findings suggest that the Act, while aiming to control price inflation, has had a multifaceted impact on the pharmaceutical sector. Stakeholders, including pharmaceutical companies, healthcare providers, patient advocacy groups, and policymakers, offered varied perspectives: while some laud the Act for its potential in controlling runaway drug prices and making healthcare more accessible, others raise concerns about possible reductions in drug innovation, disruptions to supply chains, and the sustainability of smaller pharmaceutical companies. The review identified four underlying constructs (themes) in the literature surrounding healthcare stakeholders’ perceptions of the IRA’s impact upon prescription drugs: pricing and/or dictation pricing issues, topics related to patent law and pharmaceuticals, processes surrounding the IRA’s (2022) rules and regulations, and potential threats to the pharmaceutical industry concerning the research and development of future medications. The complex interplay of the Act’s implications underscores the importance of ongoing assessment and potential iterative policy refinements as implementation endures. Full article
