As climate change intensifies and 2023 sets the record for the hottest year, the Amazonian region faces severe drought, leading to a hydroelectricity crisis. This study examines the effects of using environmentally harmful backup power solutions, which are all too common in developing countries—specifically, diesel-powered generators—on urban air quality in Quito, Ecuador, during the hydroelectric crisis of 2023/2024. The impact of the blackouts on air pollution is assessed by comparing it to a reference period before the crisis and to an earlier year with similar weather conditions. The findings indicate that extended blackouts (up to 8 h per day) considerably increased concentrations of SO₂ (180%), CO (43%), NO₂ (39%), and PM_2.5 (20%) compared to ‘normal’ conditions. Conversely, O₃ pollution levels decreased (−6%). Our findings suggest potential respiratory and cardiovascular health risks for the urban population, highlighting the urgent need for improved energy infrastructure and cleaner backup power solutions in the developing world. Addressing these challenges is critical for ensuring a healthier and more sustainable urban future amidst climate change projections. Full article

Motivated by the recent putative reproducibility crisis, we discuss the relationship between the replicability of scientific studies, the reproducibility of results obtained in these replications, and the philosophy of statistics. Our approach focuses on challenges in specifying scientific studies for scientific inference via statistical inference and is complementary to classical discussions in the philosophy of statistics. We particularly consider the challenges in replicating studies exactly, using the notion of the idealized experiment. We argue against treating reproducibility as an inherently desirable property of scientific results, and in favor of viewing it as a tool to measure the distance between an original study and its replications. To sensibly study the implications of replicability and results reproducibility on inference, such a measure of replication distance is needed. We present an effort to delineate such a framework here, addressing some challenges in capturing the components of scientific studies while identifying others as ongoing issues. We illustrate our measure of replication distance by simulations using a toy example. Rather than replications, we present purposefully planned modifications as an appropriate tool to inform scientific inquiry. Our ability to measure replication distance serves scientists in their search for replication-ready studies. We believe that likelihood-based and evidential approaches may play a critical role towards building statistics that effectively serve the practical needs of science. Full article

In the modern era, we increasingly encounter threats and challenges caused by climate change, and as a result, “green” thinking has become a necessity in every person’s life. It is believed that environmentally focused thinking can be invigorated with the help of Homo Climaticus, who is defined as a rational person in a climate crisis. However, it must be recognized that to understand the essence of Homo Climaticus, it must be compared with other archetypes. Within the framework of this article, the authors have evaluated the interaction between Homo Climaticus and Homo Religiosus in the context of environmental management. The analysis of these archetypes outlines the synergies and conflicts that arise from the fundamental differences in the worldviews of these archetypes, although both are committed to preserving the environment. Homo Climaticus is fundamentally based on science and data related to environmental management, whereas Homo Religiosus is motivated by faith-based ethics and the moral necessity to protect the world created by God. Recognizing and utilizing the strengths of both these archetypes can create more effective environmental management. Such an interdisciplinary approach indicates that collaboration between scientific and religious communities can provide a comprehensive strategy for addressing global environmental issues.

This study explores the influence of risk disclosure levels and types on the readability of annual reports of non-financial firms in the UK during the COVID-19 outbreak. It further investigates how the disclosure of COVID-19-related information moderates the relationship between risk disclosure and readability. The study uses a content analysis approach and CFIE software to measure the level of risk disclosure and readability in the annual reports of non-financial firms listed on the FTSE all-share from 2019 to 2021. The results show a positive and significant effect of risk disclosure level on readability, which is stronger for firms that disclosed COVID-19 information. Different types of risk disclosure have varying effects on readability, with COVID-19 risk, credit risk, and strategic risk positively affecting readability, while operational risk negatively affects it. The study contributes to the literature on information asymmetry and institutional theory by demonstrating how risk disclosure and readability are influenced by external factors like the COVID-19 outbreak and internal factors such as firm characteristics and types of risks. It introduces a new risk definition and category specific to the COVID-19 pandemic and develops new measurements for risk disclosure, including credit, liquidity, market, operational, business, strategic, and COVID-19 risks. The study provides valuable insights for managers, investors, regulators, and standard setters on the relationship between risk disclosure and readability in annual reports. It highlights the importance of disclosing COVID-19-related information to enhance the readability and understandability of financial communication. The paper contributes to the literature and practice on risk disclosure, readability, and financial communication during crises. Full article

The research states that the exacerbation of the climate crisis observed in recent years is accompanied by an increase in ground-level temperatures, natural disasters, loss of water resources, and other extreme weather events, which significantly impact the economy, water, and food security of water-dependent countries and the expected consequences shortly. For this purpose, during this research, data from the Bureau of National Statistics of the Agency for Strategic Planning and Reforms of the Republic of Kazakhstan were studied, and a sample of private indicators of the country’s agribusiness digitalization potential was made, which were further normalized to construct a mathematical model of the correlation between the level of digitalization of the agricultural sector and the volume of water consumed by agribusiness. The feasibility of using agricultural notes (electronic agricultural receipts) in Kazakhstan’s agribusiness as an innovative tool for attracting funds to develop agricultural production is justified. It is highlighted that the agricultural note has the potential to become a successful tool for attracting funds for the digitalization of the agricultural sector, provided it acquires the status of a full-fledged market product, in which state regulation of Kazakhstan’s agribusiness digital transformation plays a significant role.

This study is focused on one of the most active features of the Hellenic Volcanic Arc Southern Aegean Sea, the Santorini Island Volcanic Complex (SVC). The recent volcano-tectonic crisis in the intracalderic area has emerged the need for closer monitoring of the region. The 2011–2012 unrest has been attributed to the augmentation of fluid flow inside local mapped fracture zones. After March 2012, the seismic activity dropped significantly, raising questions about whether we would have a long period of quiescence or be on a break before the next period of unrest. In this research, a re-examination of the seismic outbreak of 2011–2012 was conducted by adding more travel-time data from 2013 while we further analyzed the waveform data from 2014 to May 2024 to explore the differences of the SVC body-wave velocity structure by performing seismic tomography in these two time windows. The new dataset serves to identify the state of the Santorini Volcanic Complex. The results show a significant reduction in Vp and Vs anomalies at shallow depths since the period of unrest. At the same time, the distribution of Vp/Vs ratio remains high (>1.87) in the area NNE of Kameni at a shallower depth (2 km). The areas of Christiana Islands and Columbo volcano are mainly characterized by negative body-wave anomalies and low Vp/Vs ratio (1.56–1.64) at shallow depths for the study period, while a possible explanation to results in the submarine volcano may be explained by dry steam/gas phases that may have resulted in the generation of the swarms that occurred in the region.

The purpose of the Diné Teachings and Public Health Students Informing Peers and Relatives about Vaccine Education (RAVE) project was to develop strategies for health communication that addressed COVID-19 vaccine safety for residents of the Navajo Nation. The RAVE project developed a 16-week course using the Diné Educational Philosophy as a framework to train Diné College (DC) public health undergraduate students (n = 16) as health messengers to share COVID-19 vaccine safety information with unvaccinated peers and relatives. An online community survey (n = 50) was used to assess DC community vaccination perceptions to guide course development. The two primary reasons survey participants got vaccinated were to protect the health of others [82% (n = 41)] and to protect their own health [76% (n = 38)]. A pretest/post-test and a retrospective pretest (n = 13) were implemented to determine course effectiveness. A finding approaching significance was related to student confidence in being health messengers (9.1% increase). RAVE offers the first example in the published literature of successfully training American Indian undergraduate students in the context of a public health course to contribute to the response workforce during a public health crisis.

The semiconductor industry is a pivotal hub in the global information sector, in which superpowers compete for technological dominance. As a strategic, leading, and foundational sector, it is vital for advancing China’s manufacturing ambitions through new waves of transformation and upgrades. Therefore, of particular concern is the crisis surrounding China’s semiconductor supply chain insecurity and the intensifying U.S. sanctions on China’s high-tech companies. As such, in this study, we utilize data from China’s semiconductor enterprises, investments, and related statistics from 2002 to 2020; industrial agglomeration indicators; and a social network analysis to examine the spatiotemporal pattern, industrial agglomeration, and investment networks of six key value chain segments: wafer materials, packaging materials, semiconductor equipment, integrated circuit (IC) design, manufacturing, and testing/packaging. The research focuses on how these sectors can contribute to sustainable growth and economic responsibility within China’s semiconductor industry. Accordingly, the core questions explored were as follows: what are the provincial-level spatial production dynamics and evolutionary characteristics within China’s semiconductor industry, and how do the inter-provincial investment patterns manifest? The findings reveal the following: (1) The findings reveal a strong concentration of firms in the Eastern Coastal region, particularly in Jiangsu, Shanghai, Zhejiang, and Guangdong. Additionally, IC design exhibits the highest clustering, and other segments such as wafer materials, manufacturing, and packaging/testing are relatively concentrated, whereas equipment distribution is more dispersed. (2) The industry expanded steadily from 2002 to 2013, with a rapid expansion from 2014 to 2020, particularly in Guangdong. (3) Investment patterns are characterized by local and regional focus, strongly influenced by geographical proximity. This study aims to reveal the geographic concentration patterns of China’s semiconductor industry and to explore its investment networks. The findings are intended to provide theoretical support for optimizing sustainable industrial layouts, promoting sustainable industrial practices, and guiding policy formulation. Furthermore, in the broader context of de-globalization, this study offers insights and recommendations for strengthening industrial autonomy and sustainability in response to external challenges, thereby contributing to the sustainable development of a more robust domestic semiconductor supply chain. These insights are particularly significant in safeguarding China’s technological independence and future economic stability amid global tensions. Furthermore, by integrating sustainability into its semiconductor industry, China can create a more resilient, self-sufficient, and environmentally responsible industrial sector, capable of meeting both domestic and global demands. As China continues to expand its semiconductor industry, incorporating sustainable development principles will be essential for long-term success. The sustainable practices not only ensures compliance with environmental regulations but also enhances industrial competitiveness, promotes green techniques and contributes to broader societal goals. This aligns with China’s broader ambitions for sustainable development and positions the country as a key player in the global green technology revolution. Full article

In 2015, Catalonia introduced sickle cell disease (SCD) screening in its newborn screening (NBS) program along with standard-of-care treatments like penicillin, hydroxyurea, and anti-pneumococcal vaccination. Few studies have assessed the clinical impact of introducing NBS programs on SCD patients. We analyzed the incidence of SCD and related hemoglobinopathies in Catalonia and the change in clinical events occurring after introducing NBS. Screening 506,996 newborns from 2015 to 2022, we conducted a retrospective multicenter study including 100 screened (SG) and 95 unscreened (UG) SCD patients and analyzed SCD-related clinical events over the first six years of life. We diagnosed 160 cases of SCD, with an incidence of 1 in 3169 newborns. The SG had a significantly lower median age at diagnosis (0.1 y vs. 1.68 y, p < 0.0001), and initiated penicillin prophylaxis (0.12 y vs. 1.86 y, p < 0.0001) and hydroxyurea treatment earlier (1.42 y vs. 4.5 y, p < 0.0001). The SG experienced fewer median SCD-related clinical events (vaso-occlusive crisis, acute chest syndrome, infections of probable bacterial origin, acute anemia requiring transfusion, acute splenic sequestration, and pathological transcranial Doppler echography) per year of follow-up (0.19 vs. 0.77, p < 0.0001), a reduced number of annual emergency department visits (0.37 vs. 0.76, p < 0.0001), and fewer hospitalizations (0.33 vs. 0.72, p < 0.0001). SCD screening in Catalonia’s NBS program has effectively reduced morbidity and improved affected children’s quality of life. Full article

Infectious disease epidemics have played a crucial role in shaping public health responses, particularly in global health crises. This study emerges as part of the efforts to prepare effective responses to potential future pandemics, leveraging lessons learned during the COVID-19 crisis. The research uses an adapted compartmental epidemiological model and a synthetic multi-agent community to investigate how social variables influence epidemic forecasts in socioeconomically vulnerable regions. Focusing on the simulation of epidemic dynamics in the socio-economically disadvantaged neighbourhood of Ilha Joana Bezerra in Recife, this study examines the impacts of social distancing strategies and other control measures, such as face masks and moderate social isolation. Through the adapted SEPAI3R3O model, which includes compartments for pre-symptomatic and asymptomatic states, this study provides a detailed analysis of disease dynamics in contexts characterised by high social vulnerability. The results underscore the importance of public health policies adapted to socio-economic factors, emphasising the need for continuous preparedness to manage future epidemic threats in vulnerable communities effectively.

The increasing use of illicit drugs has become a major global concern. Illicit drugs interact with the brain and the body altering an individual’s mood and behavior. As the substance-of-abuse (SOA) crisis continues to spread across the world, in order to reduce trafficking and unlawful activity, it is important to use point-of-care devices like biosensors. Currently, there are certain conventional detection methods, which include gas chromatography (GC), mass spectrometry (MS), surface ionization, surface-enhanced Raman spectroscopy (SERS), surface plasmon resonance (SPR), electrochemiluminescence (ECL), high-performance liquid chromatography (HPLC), etc., for the detection of abused drugs. These methods have the advantage of high accuracy and sensitivity but are generally laborious, expensive, and require trained operators, along with high sample requirements, and they are not suitable for on-site drug detection scenarios. As a result, there is an urgent need for point-of-care technologies for a variety of drugs that can replace conventional techniques, such as a biosensor, specifically an immunosensor. An immunosensor is an analytical device that integrates an antibody-based recognition element with a transducer to detect specific molecules (antigens). In an immunosensor, the highly selective antigen–antibody interaction is used to identify and quantify the target analyte. The binding event between the antibody and antigen is converted by the transducer into a measurable signal, such as electrical, optical, or electrochemical, which corresponds to the presence and concentration of the analyte in the sample. This paper provides a comprehensive overview of various illicit drugs, the conventional methods employed for their detection, and the advantages of immunosensors over conventional techniques. It highlights the critical need for on-site detection and explores emerging point-of-care testing methods. The paper also outlines future research goals in this field, emphasizing the potential of advanced technologies to enhance the accuracy, efficiency, and convenience of drug detection. Full article

Despite efforts to solve the housing crisis in Saudi Arabia, there are still many challenges related to providing affordable housing due to the high cost of production. Cooperative housing is an approach that achieves the principle of affordable housing through collective effort and effective management. However, activating sustainable cooperative housing production is a process that involves reforming the entire housing system, including policies, subsidies, management, and financing. This study aims to develop a conceptual framework to activate cooperative housing production in Saudi Arabia so as to achieve affordable housing. The research methodology relies on a theoretical approach to identify the relationship between cooperative housing and urban systems so as to determine the factors of cooperative production, including housing policies, management, subsidies, and financing, within a participatory framework. This study focuses on monitoring the situation of cooperative housing and local housing challenges using theoretical concepts, indicators, and international experiences. This study proposes a comprehensive framework for the production of cooperative housing that effectively affects the Saudi housing market and is compatible with the needs of people with low incomes.

This study considers ways to increase the consumption of sustainable fashion given the significant environmental and social damages associated with the industry. A series of experiments were conducted examining the impacts of choice architecture (nudges) under field conditions in collaboration with one of Israel’s largest shopping centers. This study sought to identify which interventions at the retail level successfully motivate sustainable fashion behavioral change regarding purchases and willingness to pay more, along with agreement with several statements regarding the climate crisis and sustainable fashion. Among the types of nudges examined in this field study were providing information, increasing accessibility to sustainable alternatives and appealing to social identity in relation to demographics and green self-image. This study found that offering alternatives to consumers constituted the most effective way to “nudge” consumers toward more sustainable purchasing behavior. Nonetheless, this does not negate the contribution of providing information and strengthening social norms regarding sustainable fashion. Additionally, in all groups, most participants reported that they did not know how to distinguish between sustainable and non-sustainable fashion, nor did they believe that the clothes they purchased were actually sustainable. The findings emphasize the need for policies that will increase the accessibility of sustainable fashion. Full article

Water scarcity in Chile has been increasing in recent years, particularly in the central-northern region, associated with a sustained decrease in rainfall and the effects of climate change. This study characterizes the hydrosocial cycle in the Metropolitan Region of Santiago, Chile, with a focus on rural areas, examining the relationship between water availability and socioeconomic factors. For this, demographic data and data related to water demand and use, obtained from government databases, were used. In addition, geographic information systems (GIS) were used for spatial analysis and map creation. Finally, surveys were conducted in rural schools and households to obtain information on water use perceptions and practices. The results show inequalities in access to water with a moderate negative correlation between poverty and water connection/consumption. Rural areas exhibited stronger negative correlations, indicating a greater impact of poverty on water access. Water-saving practices, such as reusing washing water for irrigation, were prevalent in rural households. These results highlight the importance of the hydrosocial cycle to understand the dynamics and factors that shape water demand and consumption in a highly complex region. Full article

Due to the consequences of fires, new and environmentally friendly firefighting techniques are constantly being sought. There are many methods of extinguishing flames around the world. One of them is a technique that uses acoustic waves for extinguishing, which can be seen as repeated sequences of molecular compression and dilation (acoustic waves transfer energy due to the movements of molecules and atoms). This research shows a new approach to the extinguishing of flames. In practice, the extinguishing capabilities of low-frequency modulated and unmodulated acoustic waves were tested on a laboratory station, the main component of which was a high-powered acoustic extinguisher (the nominal power was equal to 1700 W). A B&C 21DS115 woofer was applied as a sound source. A Rigol DG4102 and a Proel HPX2800 were used as an acoustic generator with a modulator and as a power amplifier, respectively. In this paper, the presented results are limited to extinguishing candle flames. The tests made it clear that flames can be extinguished using properly generated and directed acoustic waves. As the results indicate, it becomes possible to effectively extinguish flames with both low-frequency modulated and unmodulated acoustic waves, which brings many benefits. Full article
