Introduction and purpose: The article deals with the problem of obesity, which significantly increases the number of cases among children, adolescents and adults all over the world, leading to the occurrence of systemic disorders. A noticeable increase in the incidence of atherosclerosis, metabolic syndrome and diabetes leads to a reduction in life expectancy. The main aim of the work is to emphasize the seriousness of the contemporary problem, which causes impairment of the functioning of many systems. A secondary goal is to indicate the current standards of obesity treatment and how to deal with overweight. Brief description of the state of knowledge: Obesity is a disease that affects nearly 800 million people around the world and affects every fourth Pole. Uncontrolled weight gain is caused; lifestyle changes, consumption of highly processed foods, and genetic and endocrine factors. It is a chronic disease with a tendency to relapse, with serious consequences and in need of diagnostics, personalized treatment, and often associated with psychological support. Material and methods: The article analyzes the research to date and the latest treatment methods, which show that a person struggling with obesity is at risk of over 200 complications, including, for example, fatty liver, stroke, type 2 diabetes or cancer. Results and conclusion: According to our analysis, obesity is a pathological condition that is truly life-threatening. Despite the society's downplay of the problem, people affected by this disease struggle with many comorbidities that worsen their quality of life. [ABSTRACT FROM AUTHOR]

Silicon monoxide nanowires have become ubiquitous in twenty-first century technology due to their superior photoelectric properties, widely utilized in semiconductor manufacturing and emerging energy fields. While numerous studies have concentrated on tailoring material properties, scant attention has been paid to the impact of process parameters on the productivity of silicon monoxide during synthesis. Through response surface methodology, the effects of holding time, heating temperature, and Si/SiO2 molar ratio on the volatilization ratio of silicon monoxide have been investigated. The optimization of silicon monoxide nanowire preparation via vacuum silicothermic reduction was aimed at achieving maximum efficiency. According to the established mathematical model, the volatilization ratio of silicon monoxide reaches 92.057% when the holding time is 126 min, the heating temperature is 1663 K, and the molar ratio is 1. A comprehensive analysis revealed that temperature is the most significant factor affecting silicon monoxide volatilization among the studied parameters. Furthermore, the reduction slag of the system was characterized and analyzed. The results indicate that vacuum conditions can lower the starting temperature of the silicothermic reduction, thereby promoting the volatilization of SiO(g). [ABSTRACT FROM AUTHOR]

Enhanced warming of the Arctic region relative to the rest of the globe, known as Arctic amplification, is caused by a variety of diverse factors, many of which are influenced by the Atlantic meridional overturning circulation (AMOC). Here, we quantify the role of AMOC changes in Arctic amplification throughout the twenty-first century by comparing two suites of climate model simulations under the same climate change scenario but with two different AMOC states: one with a weakened AMOC and another with a steady AMOC. We find that a weakened AMOC can reduce annual mean Arctic warming by 2 °C by the end of the century. A primary contributor to this reduction in warming is surface albedo feedback, related to a smaller sea ice loss due to AMOC slowdown. Another major contributor is the changes in ocean heat uptake. The weakened AMOC and its associated anomalous ocean heat transport divergence lead to increased ocean heat uptake and surface cooling. These two factors are inextricably linked on seasonal timescales, and their relative importance for Arctic amplification can vary by season. The weakened AMOC can also abate Arctic warming via lapse rate feedback, creating marked cooling from the surface to lower-to-mid troposphere while resulting in relatively weaker cooling in the upper troposphere. Additionally, the weakened AMOC increases the low-level cloud fraction over the North Atlantic warming hole, causing significant cooling there via shortwave (sw) cloud feedback despite the overall effect of sw cloud feedback being a slight warming of the average temperature over the Arctic.

In the past decade, profound political and economic transformations have reshaped the landscape of globalization and challenged the conventional notions of the liberal international order. The traditional boundaries between the economy and security realms have become blurred, giving place to a geoeconomic turn illustrated by the high utilization of economic statecraft in international politics. While much scholarly attention has been devoted to understanding the geoeconomic strategies of global powers like the US and China, the agency and roles of emerging and developing countries, notably those in Latin America, have often been overlooked. This article addresses this gap by examining how Latin American nations engage in 21st-century geoeconomic dynamics. Using qualitative comparative analysis across 18 case studies, the study assesses the conditions and key characteristics of geoeconomic actions involving Latin American countries since 2017. The article presents a typology that sheds light on the mechanisms at play within economic statecraft in the region through six different situations: (a) local geopolitical-driven economic statecraft, (b) Latin American value-driven economic statecraft, (c) extra-regional sanctions, (d) economic inducement strategy, (e) coercive strategy for strategic assets and technologies, and (f) precautionary defensive economic statecraft. The contribution is twofold: On the one hand, the article casts light on the different facets Latin American countries have in the geo-economic trends; on the other hand, the analysis and classification of these situations help understand the links between economic and strategic policies.

In this study, we conducted a low-temperature exothermic (LTE) investigation on 1-year-old (1a) branches of sixteen peach cultivars through a differential thermal analysis (DTA) procedure. We used a three-point approach to determine the lethal injury temperature (LT-I) of the xylem, the LTE correlation indexes, and the subordinate function value method were applied to compare cold hardiness of sixteen peach varieties. The results showed that the slope of the LT-I for the xylem of sixteen peach cultivars was different, and the LTE indexes were significantly different. Among all the studied varieties, the cold hardiness was strongest in Donghe No.1, followed by Wangjiazhuangmaotao No.2 and Hunchun. Qiuyan and Yanhong are second, and belong to the cold-resistant type; Qiuyi, Okubo, Zhongnongjinhui, and Chunmei, exhibited medium cold hardiness. Zhongtaohongyu, Spring snow, Yufei, and Zhongyou No.8 varieties exhibited low hardiness; while the 21st century, Golden Honey No. 1 and Zhonghuashoutao have the worst cold hardiness and are the weakest cold-hardiness types. In addition, the injury degrees of xylem from LT-I analysis were significantly related to the browning rates (BR) and electrolytic leakage (EI) from traditional low temperature freezing analysis. It is demonstrated that the LTE analysis is a simple, accurate, and practical method for identifying the cold hardiness of 1a branches of peach. [ABSTRACT FROM AUTHOR]

We investigate 21st-century hydroclimate changes over the United States (US) during winter and the sources of projection uncertainty under three emission scenarios (SSP2–4.5, SSP3–7.0, and SSP5–8.5) using CMIP6 models. Our study reveals a robust intensification of winter precipitation across the US, except in the Southern Great Plains, where changes are very small. By the end of the 21st century, winter precipitation is projected to increase by about 2–5% K−1 over most of the US. The frequency of very wet winters is also expected to increase, with 6–7 out of 30 winters exceeding the very wet threshold under the different scenarios. Our results suggest that the enhancement of future winter precipitation is modulated largely by coupled dynamic and thermodynamic responses, though partly offset by thermodynamic responses. Overall, our results highlight a high likelihood of increasing impacts from winter precipitation due to climate change. [ABSTRACT FROM AUTHOR]

The southern Himalayas, characterized by its dense population and hot, humid summers, are confronted with some of the world's most severe heat stress risks. This study uses the hourly ERA5 dataset (1979–2022) and CMIP6 projections (2005–2100) to evaluate past and future heat stress based on the Wet Bulb Globe Temperature (WBGT). This has significant implications for the management of occupational workloads in the southern Himalayas. Heat stress levels are classified into 6 categories (0 to 5) using WBGT threshold intervals of 23 °C, 25 °C, 28 °C, 30 °C, and 33 °C. With heat stress surpassing level 3 for almost half of the time, people are constrained to engage in less than moderate workloads to ensure their health remains uncompromised. Flow-analogous algorithm is employed to contextualize the unprecedented heat stress case in the summer of 2020 and the associated atmospheric circulation patterns from historical and future perspectives. The results show that over 80% of the time in 2020, heat stress levels were at 3 and 4. The identified circulation pattern explains 27.6% of the extreme intensity, and such an extreme would have been nearly impossible in pre-21st-century climate conditions under the identified pattern. Future projections under SSP2-4.5 and SSP5-8.5 scenarios indicate that heat stress similar to what was experienced in 2020 will likely become a common occurrence across the southern Himalayas. Under a similar circulation pattern, the heat stress levels by the end of the 21st century would be elevated by at least one category compared to the climatic baseline in over 70% of the region, leading to an additional 120.5 (420.1) million daily population exposed to the highest heat stress level under the SSP2-4.5 (SSP5-8.5) scenario.

Global warming has accelerated alpine glacier melting and led to an increased risk of glacial lake outburst floods (GLOFs). This paper extracted glacial lake boundaries in the Tienshan Mountains of Central Asia from 1990 to 2023, analyzed their spatiotemporal variations and evaluated their risk levels under current and future scenarios. The results show that glacial lakes are predominantly distributed in the Central and Western Tienshan, accounting for 75% of the total number in the Tienshan region. The number and area of glacial lakes increased by 148% (from 1837 to 4557) and 71.83% (from 119.73 to 205.73 km2) during 1990 to 2023, with moraine lake expansion predominating. In the Western Tienshan, the high or very high risk of GLOF is 3–4 times that of other areas. By the middle of the twenty-first century, GLOF risk will continue to increase, especially in the Western Tienshan. This study can provide scientific foundation for disaster mitigation in the downstream areas. [ABSTRACT FROM AUTHOR]

Significant strides have been made in understanding El Niño-Southern Oscillation (ENSO) dynamics, yet its long-lead prediction remains challenging, especially for the El Niño events after 2000. Sea surface salinity (SSS) is known to affect ENSO development and intensity by influencing ocean stratification and heat redistribution and therefore, when combined with sea surface temperature (SST) data, can potentially enhance ENSO forecast skill. In this study, we develop a deep learning (DL) model that incorporates a multiscale-pyramid structure and spatiotemporal feature extraction blocks, and the model successfully extends effective ENSO forecast lead time to 24 months for 2000–2021 with reduced effect of the spring predictability barrier (SPB). Interpretable methods are then applied to reveal the time-dependent roles of SST and SSS in ENSO forecast. More specifically, SST is critical for short-medium lead forecasts (<1 year), while SSS is important for medium-long lead forecasts (>6 months). Furthermore, we track global SST and SSS spatiotemporal shifts related to subsequent ENSO development, highlighting the importance of ocean inter-basin and tropics-extratropics interactions. With increasing availability of satellite SSS observations, our findings unveil unprecedented potential for advancing ENSO long-lead forecast skills. [ABSTRACT FROM AUTHOR]

Bangladesh, a sub-tropical monsoon climate with low-lying areas, is very susceptible to the impacts of climate change. However, there has been a shortage of studies about the periodicity and projected changes in extreme temperature in this area, which is a crucial part of adapting to climate change. A study employed a multimodal ensemble (MME) mean of 13 bias-corrected CMIP6 GCMs to fill this knowledge gap. The purpose of this study was to project changes in 8 extreme temperature indices (ETIs) across Bangladesh for the near future (2021–2060) and far future (2061–2100) under two different Shared Socioeconomic Pathways (SSPs): medium (SSP2-4.5) and high (SSP5-8.5) scenarios. The research analyzed the average spatiotemporal changes by considering the reference period from 1995 to 2014 for each indicator in future periods. The results indicate that Bangladesh is projected to see a rise in average annual temperature in the 21st century, aligning with the global average. Warm days (TX90p) and nights (TN90p) were projected to increase, while cold days (TX10p) and nights (TN10p) were expected to decrease across the country for both the near (2021–2060) and far future (2061–2100). The projected highest increase in TX90p and TN90p was 6.90 days/decade in the northeast, and the highest decrease in TX10p and TN10p was 6.22 days/decade in the southwest. The study revealed a higher rise in TN90p than TX90p, indicating a faster decline in cold extremes than a rise in hot extremes. The rising temperature would cause an increase in the spell duration index (WSDI) and growing degree day (GDD) by 5–6 and 6–7 days/decade, respectively. Therefore, immediate measures must be taken to mitigate the detrimental effects of extreme temperatures, leading to heat stress. To reduce the effects on agriculture, ecosystems, human health, and biodiversity, policymakers and stakeholders must understand these anticipated changes and adopt appropriate actions.

In an international scenario of political crisis, and with democracies weakened by the impact of populism and disinformation, the Russian invasion of Ukraine in 2022 provides a new scenario for the reactivation of war propaganda strategies. This article analyzes the digital discourse of President of Ukraine Volodymyr Zelensky on Telegram—a messaging network that favors one-way communication, immediacy, and access to communities of followers—in terms of war propaganda during the first year of the conflict, focusing on variables such as propaganda functions and techniques, the representation of the leader and the enemy, or the use of national symbols. The data-gathering technique is content analysis, which is applied to the study of the 2,075 publications made by the Ukrainian leader in the period analyzed (February 24, 2022-February 23, 2023). Results indicate a strategic orientation towards the internationalization of the conflict and the defense of a management orientation based on the mobilization of Ukraine, as well as personalized leadership and the persistence of techniques and trends of classic war propaganda in the digital political discourse of the 21st century.

In this essay, we examine the institutional affiliations of Isis contributors and editors in the second half of the twentieth century and the first decades of the twenty-first, and analyze what the articles and book reviews in Isis suggest about contributors' engagement with the field of science studies more broadly. For much of the late twentieth century, we argue, Isis was a US-dominated journal, in terms of both the affiliations of its contributors and the intellectual trends it engaged with. Methodological developments in European science and technology studies (STS), for example, were generally not reflected in Isis 's research content until many years after they were originated, although the Isis book reviews frequently considered books by STS researchers. This US dominance has begun to change in recent years, however, with the establishments of editorial offices outside the United States and an increasing number of contributions from scholars outside the US. Current citation patterns in Isis reveal that the journal's research articles reflect strong engagement with STS more broadly. [ABSTRACT FROM AUTHOR]

This article analyzes abortion experiences with misoprostol during the first decade of the 21st century in Argentina, before the legalization of the practice and the publication of the World Health Organization manuals on medication dosage. Based on in-depth interviews with women who underwent medical abortions during those years, we inquire about the mechanisms of information circulation and clandestine purchase of the drug. In addition, the article delves into experiences on the use of medication, confidence in the procedure, and the pain felt by these women from the theoretical perspective of the sociology of emotions. Among the most relevant findings is that women build networks and links to overcome the problems surrounding the practice of abortion because of the difficulty of obtaining the medication in the context of legality and illegality and the lack of information about the procedure itself and to develop a reliable method based on their own experiences.

Tropical cyclone (TC) winds control design wind speeds for much of the eastern United States. Those winds are likely to intensify with climate change, but climate change was not considered in the ASCE 7-22 design wind speed maps, potentially causing many structures to be designed with unacceptably high levels of risk. In this study, we investigate (1) the increases in design wind speed due to climate change; and (2) the resulting risk to structures if climate change is not considered. We estimated the design wind speeds for US counties affected by TCs along the Gulf and Atlantic coasts using nonstationary methods based on a set of synthetic TCs (1,000–1,500 year simulations) downscaled from the latest global climate projections (CMIP6) for the high-emissions scenario (SSP5-8.5). It was found that over the 21st century, 50-year return period winds would increase by an average of around 10% along the US Gulf and Atlantic coasts. Depending on the risk category, design lifetime, and year of construction, design wind speeds (targeting lifetime exceedance probability) are projected to increase by an average of 3%–6% for all counties studied and 6%–15% for coastal counties. For Risk Category II–IV structures, depending on the design lifetime and year of construction, 8%–36% of all counties studied and 25%–66% of coastal counties would experience projected lifetime exceedance probabilities that were at least two risk categories too low; for example, in up to 26% of all counties studied and 54% of coastal counties, a Risk Category III structure would be effectively designed as Risk Category I or lower.

Between the late 1960s and the early twenty-first century, the process by which astronomers identified gravitational lenses went from a time-consuming spectroscopic experiment to a two-second glance at a telescope image. This article analyzes discoveries of gravitational lenses over this period to explore the questions: How did astronomers learn to see new objects in the sky, and how did they train their eyes to effortlessly recognize these patterns in nature? Rather than separating procedural and intuitive approaches, I argue that the mathematical modeling and the spectroscopic identifications of the sixties and seventies were necessary scaffolding for the development of expert intuition in the eighties. By developing an intuition for what a lens looked like, astronomers increasingly relied on their own expert judgment rather than spectroscopy or calculations to initially identify lensing candidates. Through this history, I highlight intuition as a skill and explore the methods by which scientists train and retrain their intuition over the course of a career. The gamut of gravitational lens discoveries reveals that scientists used models to not only describe the world as it is but also to teach themselves what it could look like. To retrain their intuition and to learn how to see gravitational lenses, astronomers learned to see their models. [ABSTRACT FROM AUTHOR]

Societal Impact Statement: Political interests and power structures shape state‐led crop conservation and food policy. As a crop that relates to culture and belonging, the chile crop is ideal for exploring how food security policy and crop conservation schemes integrate aspects beyond staple crops, calories and/or electoral incentives. What do these schemes mean for the food and ingredients we love? Reflecting from this perspective can be useful to grasp, re‐frame and create more effective and inclusive food policies—ones that embody and valorise flavour, identities and territories beyond statements on paper. Summary: In line with the Food and Agriculture Organisation's (FAO) international action plan for crop genetic resources, the Mexican state inaugurated the National System of Genetic Resources for Food and Agriculture (SINAREFI) in 2002. In this paper, I explore SINAREFI's interest in landraces and in situ conservation through the case of chile pepper, set under the Ministry of Agriculture's interests of promoting industrial agriculture and paternalistic food security welfare programmes.Through the analyses of existing literature on food security in Mexico state programmes, archival work and interviews, this article analyses how discourses on food security shape research trajectories, some of which are inevitably constrained by current market‐based agricultural systems.By exploring the state's chile research and conservation programme, this work demonstrates the complexity of international food security discourse and its application domestically. Particularly, this analysis highlights the limitations of state crop research and conservation efforts imposed by contradictory agricultural policies. In the case of chile, its link to Mexican culture and diet uncovers an important, but often overlooked, aspect of food security: flavour.In the case of chile, a non‐staple but culturally symbolic crop, welfare programmes remained paternalistic and focused on caloric intake despite the transformation of national discourse on food security towards the integration of landraces and local cultures through the inauguration of SINAREFI. This case study reflects on the limits of current framings and strategies regarding food security and the need to direct policies towards local food sovereignty to achieve the necessary stability for food security to endure.

Wetlands are crucial components of the Earth's system, interacting with various processes such as the hydrological cycle, energy exchanges with the atmosphere, and global nitrogen and carbon cycles. The future trajectory of wetlands is anticipated to be influenced not only by direct human activities, but also by climate change. Here we present our assessment of climate‐driven global changes in wetlands extent, focusing on the main wetland complexes. We used an approach based on the Topographic Hydrological model (TOPMODEL) and soil liquid water content projections from 14 models of the Coupled Model Intercomparison Project Phase 6 (CMIP6). Our analysis reveals a consistent decrease in wetlands extent in the Mediterranean, Central America, and northern South America, with a substantial loss of 28% in the western Amazon Basin for the end of the 21st century (2081–2100) under the SSP370 scenario. Conversely, Central Africa exhibits an increase in wetlands extent, except in the Congo Basin. Nevertheless, most of the areas studied (80%) present uncertain results, due to conflicting projections of changes between the models. Notably, we show that there is significant uncertainty among CMIP6 models regarding liquid soil water content in high latitudes. By narrowing our focus to 10 models, which seem to better represent the thawing of permafrost, we obtain a better inter‐model agreement. We then find a modest declines in the overall global area (<5%), but an average loss of 13% beyond 50°N. Specific areas like the Hudson Bay Lowlands experiencing a 21% decrease and the Western Siberian Lowlands a 15% decrease. Plain Language Summary: Wetlands are vital ecosystems, that exchange matter and energy with other components of the Earth's system. They are expected to face changes in their functioning and extent due to both human activities and climate change. Our assessment using advanced models reveals consistent shrinking of wetlands extent in the Mediterranean, Central America, and parts of South America, with a significant loss projected in the western Amazon Basin. Conversely, Central Africa may see an increase, except in the Congo Basin. However, much of our findings carry uncertainty due to conflicting model projections, particularly regarding soil water content in high latitudes. Focusing on models better representing permafrost thawing, we find a modest global decline in wetland area, with notable decreases in specific regions like the Hudson Bay and Western Siberian Lowlands. Key Points: Projections of climate‐driven changes in wetlands extent are analyzed using the sixth phase of the Coupled Model Intercomparison ProjectConsistent decrease in wetlands extent are projected over the Mediterranean, Central America, and Amazon Basin in South AmericaThere is significant uncertainty among models in high latitudes, but a subsample of models indicate a decrease in boreal wetlands extent [ABSTRACT FROM AUTHOR]

Educators view active learning as a pedagogical enabler for preparing students for the demands of today’s workplaces and equipping students with 21st century skills such as critical thinking, problem solving, collaboration, and teamwork. However, there seems to be a noticeable incongruity between the eagerness on the development of 21st century skills and the learning spaces where these skills are intended to be acquired. The significance of learning spaces and their potential for facilitating or impeding students’ active engagement should not be overlooked. Considering the indispensability of technology in today's world, its integration becomes crucial not only in today's pedagogy and curriculum but also in the design of learning spaces. This study aims to investigate teachers’ perspectives of teaching in a technology-enhanced active learning (TEAL) classroom by exploring their experiences of using the TEAL classrooms, the factors affecting their experiences, and how these factors shape teaching experiences from the viewpoint of teacher participants. This study adopts a mixed methods approach where quantitative and qualitative data collection and analysis are incorporated to address the research questions. Findings of the study suggest that the majority of classroom users had a positive overall impression of the TEAL classrooms with some discussing the challenges they encountered. Analysis of the data shows both classroom-related and non-classroom related factors influencing teachers’ teaching experiences. Classroom-related factors encompass aspects such as classroom layout and the technology embedded within the classroom environment. On the other hand, non-classroom related factors are classified into course-related, teacher-related, and student-related factors. [ABSTRACT FROM AUTHOR]

Understanding the extent to which people and wildlife overlap in space and time is critical for the conservation of biodiversity and ecological services. Yet, how global change will reshape the future of human-wildlife overlap has not been assessed. We show that the potential spatial overlap of global human populations and 22,374 terrestrial vertebrate species will increase across ~56.6% and decrease across only ~11.8% of the Earth's terrestrial surface by 2070. Increases are driven primarily by intensification of human population densities, not change in wildlife distributions caused by climate change. The strong spatial heterogeneity of future human-wildlife overlap found in our study makes it clear that local context is imperative to consider, and more targeted area-based land-use planning should be integrated into systematic conservation planning.

The collapse of ice shelves could expose tall ice cliffs at ice sheet margins. The marine ice cliff instability (MICI) is a hypothesis that predicts that, if these cliffs are tall enough, ice may fail structurally leading to self-sustained retreat. To date, projections that include MICI have been performed with a single model based on a simple parameterization. Here, we implement a physically motivated parameterization in three ice sheet models and simulate the response of the Amundsen Sea Embayment after a hypothetical collapse of floating ice. All models show that Thwaites Glacier would not retreat further in the 21st century. In another set of simulations, we force the grounding line to retreat into Thwaites' deeper basin to expose a taller cliff. In these simulations, rapid thinning and velocity increase reduce the calving rate, stabilizing the cliff. These experiments show that Thwaites may be less vulnerable to MICI than previously thought, and model projections that include this process should be re-evaluated. [ABSTRACT FROM AUTHOR]

In this study, we investigated the triple‐dip La Niña during 2020–2022 by comparing it with the previous (1973–1975 and 1998–2000) La Niña events. We found that the cold sea surface temperature (SST) in the eastern equatorial Pacific was moderate during the study period; however, the accompanying near‐surface easterly wind anomaly was unusually stronger during its lifecycle than during the previous two events. The maintenance of 2020–2022 La Niña appeared to be attributable to the strong zonal SST gradient. The strong zonal SST gradient resulted from the La‐Niña‐associated interannual SST anomaly, which was further enhanced by a warming trend in the western equatorial Pacific (165°E−160°W, 5°S–5°N) and the interdecadal oscillation of the Pacific‐Decadal‐Oscillation‐associated cold SST in the eastern tropical Pacific. The warming trend in the western equatorial Pacific, with a faster warming speed than global warming, also modified the La‐Niña‐associated Pacific–North American teleconnection to shifted eastward. Plain Language Summary: The La Niña during 2020–2022 was the first triple‐dip event in the 21st century. It induced several major disasters worldwide, such as the record flooding in Pakistan caused 30 million people to lose their homes and took the lives of more than 1,000 individuals. However, how this long‐duration La Niña was maintained remained unclear. The physical processes related to the 2020–2022 La Niña were investigated by comparing them with those of the previous 3‐year La Niña events (1973–1975 and 1998–2000). The major distinctive feature of the 2020–2022 La Niña was the moderate negative sea surface temperature (SST) anomaly in the eastern equatorial Pacific, which was accompanied by an unusually strong near‐surface easterly wind anomaly in the central equatorial Pacific. Our study revealed the maintenance of the triple‐dip La Niña during 2020–2022 was attributable to the strong zonal SST gradient between the western and eastern equatorial Pacific, with the western waters being dominated by a warming trend and the eastern waters being influenced by the cold phase of the Pacific Decadal Oscillation. The warming trend in the western equatorial Pacific provided a favorable background for a triple‐dip La Niña event and also modified the La‐Niña‐associated Pacific–North American teleconnection so that it shifted eastward. Key Points: The La‐Niña‐associated cold SST was moderate during 2020–2022, but the accompanying easterly wind anomaly reached an unusual highThe strong easterly was in response to the zonal SST gradient between the warm western tropical Pacific and cold eastern tropical PacificThe western equatorial Pacific SST, with a faster warming speed than global warming, modulated the PNA teleconnection to shift eastward [ABSTRACT FROM AUTHOR]

Background: As a newly emerged concept and a product of the twenty-first century, health information governance is expanding at a rapid rate. The necessity of information governance in the healthcare industry is evident, given the significance of health information and the current need to manage it. The objective of the present scoping review is to identify the dimensions and components of health information governance to discover how these factors impact the enhancement of healthcare systems and services. Methods: PubMed, Scopus, Web of Science, ProQuest and the Google Scholar search engine were searched from inception to June 2024. Methodological study quality was assessed using CASP checklists for selected documents. Endnote 20 was utilized to select and review articles and manage references, and MAXQDA 2020 was used for content analysis. Results: A total of 37 documents, including 18 review, 9 qualitative and 10 mixed-method studies, were identified by literature search. Based on the findings, six core categories (including health information governance goals, advantages and applications, principles, components or elements, roles and responsibilities and processes) and 48 subcategories were identified to form a unified general framework comprising all extracted dimensions and components. Conclusions: Based on the findings of this scoping review, health information governance should be regarded as a necessity in the health systems of various countries to improve and achieve their goals, particularly in developing and underdeveloped countries. Moreover, in light of the undesirable effects of the coronavirus disease 2019 (COVID-19) pandemic in various countries, the development and implementation of health information governance models at organizational, national and international levels are among the pressing concerns. Researchers can use the present findings as a comprehensive model for developing health information governance models. A possible limitation of this study is our limited access to some databases.

A substantial amount of research, resources, and effort has been invested in the search for a 'holy grail' of twenty-first century leadership competencies. Ironically, despite the increasing significance of leadership and the substantial investments in uncovering the attributes of successful leaders, concerns persist regarding the quality of leadership worldwide. While the literature extensively outlines 'what' twenty-first century-ready leaders should embody, there remains a gap in outlining 'how' to nurture such leaders. We contrast existing practices that have focused on teaching functional content and relying on retrospective and deficit-based competency models by advocating for a strengths-based perspective. While there has been an increasing interest in positive psychology, which promotes a shift away from prevalent deficit correction approaches towards a framework that emphasises social-emotional and meta-cognitive strengths, character strengths have received little attention in corporate leader development programmes. We argue that nurturing character strengths offers a more sustainable, self-reinforcing process for twenty-first century leader development to overcome the limitations of short-lived leadership training results that fade over time. The Values in Action Classification of Character Strengths and Virtues provides a robust framework for identifying and nurturing these strengths. However, character strengths have traditionally been viewed as personal attributes, rather than leadership competencies. We challenge traditional views on leader development by arguing that character strengths reflect the competencies required of twenty-first century-ready leaders, as these more 'humane' characteristics remain relevant over time and valued across cultures because they represent qualities that are universally appreciated in defining 'what makes a good person'.

Background. Robot‐assisted nephroureterectomy (RANU) has been more and more applied since 21st century. However, the high cost limits the widespread use of robot system. A relatively low‐cost new robotic surgical system (KD‐SR‐01™) has recently been developed in China. Objective. To assess the safety and efficacy of the KD‐SR‐01™ Surgical System in RANU. Methods. Patients with upper‐tract urothelial tumor and undergoing RANU with the KD‐SR‐01™ Robotic System were prospectively included. Surgeries were all performed by a single surgeon. Patients' demographic and clinical characteristics, perioperative data, pathology findings, and follow‐up data were collected. Key Findings. 9 patients were enrolled in this study, and the surgeries went smoothly with no conversion to open. The 1st docking time, the 2nd docking time, and the operation time were 222 s, 169 s, and 202 min respectively. No equipment‐related adverse events occurred. All patients were followed up for at least 3 months, and one patient experienced bladder recurrences. Conclusions and Clinical Implications. This study is the first to verify that the KD‐SR‐01™ robot system is effective and safe in RANU and has advantages in terms of its rotation boom during redocking and its price. This trial is registered with ChiCTR2200056672. [ABSTRACT FROM AUTHOR]

This article addresses the issue of ethics and its constitution as an individual and collective axis throughout history, and in its current (re)meanings, (re) interpretations, and (re)orientations. Its objective is to establish the ethical conceptual lines that allow for a holistic and contemporary interpretation of society in the second quarter of the current century. The premise of this article is that the constitution of ethical frameworks for society in the 21st century faces the complexity of hyper-social fragmentation and the challenge posed by the promise of the “Being-Machine” hybridization.

Along with climate warming, extreme heat events have become more frequent, severe, and seriously threaten rice production. Precisely evaluating rice heat levels based on heat duration and a cumulative intensity index dominated by temperature and humidity is of great merit to effectively assess regional heat risk and minimize the deleterious impact of rice heat along the middle and lower reaches of the Yangtze River (MLRYR). This study quantified the response mechanism of daytime heat accumulation, night-time temperature, and relative humidity to disaster-causing intensity in three categories of single-season rice heat (dry, medium, and wet conditions) using Fisher discriminant analysis to obtain the Heat Comprehensive Intensity Index daily (HCIId). It is indicated that relative humidity exhibited a negative contribution under dry heat, i.e., heat disaster-causing intensity increased with decreasing relative humidity, with the opposite being true for medium and wet heat. The Kappa coefficient, combined with heat duration and cumulative HCIId, was implemented to determine classification thresholds for different disaster levels (mild, moderate, and severe) to construct heat evaluation levels. Afterwards, spatiotemporal changes in heat risk for single-season rice through the periods of 1986–2005, 2046–2065 and 2080–2099 under SSP2-4.5 and SSP5-8.5 were evaluated using climate scenario datasets and heat evaluation levels carefully constructed. Regional risk projection explicitly revealed that future risk would reach its maximum at booting and flowering, followed by the tillering stage, and its minimum at filling. The future heat risk for single-season rice significantly increased under SSP5-8.5 than SSP2-4.5 in MLRYR. The higher risk would be highlighted in eastern Hubei, eastern Hunan, most of Jiangxi, and northern Anhui. As time goes on, the heat risk for single-season rice in eastern Jiangsu and southern Zhejiang will progressively shift from low to mid-high by the end of the twenty-first century. Understanding the potential risk of heat exposure at different growth stages can help decision-makers guide the implementation of targeted measures to address climate change. The proposed methodology also provides the possibility of assessing other crops exposure to heat stress or other extreme events. [ABSTRACT FROM AUTHOR]

[Objective] The aims of this study are to reveal the spatiotemporal variation of the annual gross primary productivity (AGPP) of grassland in northern China, and to provide an important basis for the policy formulation of grassland restoration and protection. [Methods] Based on the GPP simulation data of nine Earth system models in CMIP6, the traditional multi-model ensemble average (MME) was used to estimate the temporal and spatial changes of AGPP in grassland ecosystem of northern China in the 21st century under four future scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5). [Results] (1) The accuracy and yearly trends of the MME simulation are more accurate than other individual patterns. (2) From 1982 to 2100, the AGPP in grasslands in northern China showed a fluctuating upward trend, and the upward trend under the high greenhouse gas emission scenario was greater than the upward trend under the low greenhouse gas emission scenario. (3) Spatially, the average AGPP of grassland in northern China showed an increasing trend from northwest to southeast under both historical and future scenarios, with the lowest annual average AGPP at 308.03 g C/ (m²·a) under SSP1-2.6 scenario and the highest at 389.63 g C/ (m²·a) under SSP5-8.5 scenario. (4) Among different grassland types in the four future scenarios, the annual mean value of AGPP in temperate grassland will be the highest [445.44 g C/ (m²·a) in SSP1-2.6 scenario and 474.53 g C/ (m²·a) in SSP2-4.5 scenario]. Under SSP3-7.0, it will be 532.42 g C/ (m²·a), under SSP5-8.5, it will be 558.14 g C/ (m²·a), and sparse shrub will be the lowest [128.51 g C/ (m²·a) under SSP1-2.6]. It will be 141.31 g C/ (m²·a) under SSP2-4.5, 155.38 g C/ (m²·a) under SSP3-7.0, and 167.29 g C/ (m²·a) under SSP5-8.5. [Conclusion] The AGPP in grassland in northern China will show a significant growth trend in the future, and the change trend will increase with the increase of radiation intensity and CO2 emissions. The growth trend of AGPP under different scenarios is different, and the higher the emission scenario, the more significant the growth. Future research on AGPP change of grassland in northern China should be strengthened. [ABSTRACT FROM AUTHOR]

Theoretically, a poem can begin in any way. What does it mean that in practice, poems often begin in a particular way—that is, by returning to a fragment of some prior thing? We see this in the encore of John Milton's opening to Lycidas ('Yet once more, O ye laurels, and once more'); differently, we see this in the widely used convention of the poetic epigraph (for instance, T. S. Eliot's 'The Love Song of J. Alfred Prufrock' begins with six lines from Dante's Inferno). While there is an established model for understanding the beginning as an act that invokes poetic precedent, this paper seeks to expose the beginning's logic of return to a broader sense of language that is beyond the remit of poetic tradition as such. With a focus on the epigraph, this paper thinks about the everyday existence of poems and about how this existence relates to ordinary language, asking, how do these different modes of language function together? How does ordinary language collude in the creation of poetry? In its enactment of the passage of language from one mode of existence to another, the beginning of a poem might offer some answers to these questions. [ABSTRACT FROM AUTHOR]

The link between the escalation of global warming and the increase in extreme precipitation events necessitates a deeper understanding of future trends. This study focused on the dynamics of extreme rainfall in Hubei Province throughout the 21st century, a region already sensitive to climatic shifts and extreme weather occurrences. Using the high-resolution global climate model RegCM4 driven by another high-resolution model, HadGEM2-ES, and based on the representative concentration pathway (RCP8.5) emissions scenario, this research predicted the changes in rainfall patterns in Hubei Province during the summer of the 21st century. The accuracy of the adjusted model was confirmed through the use of five extreme rainfall indices (EPIs), namely maximum 5-day amount of precipitation (RX5day), number of heavy rain days (R10), the simple daily intensity index (SDII), consecutive dry days (CDD), and consecutive wet days (CWD), that measured the intensity and frequency of such events. In particular, excluding the index for continuous dry days (CDD), there was an anticipated increase in extreme rainfall during the summer in the mid-21st century. The number of heavy rain days (R10mm) increased significantly (p < 0.05) in the southeastern parts, especially for Wuhan, Xiantao, Qianjiang, Jinzhou, and Ezhou. The EPI values were higher in southeastern Hubei. Consequently, areas such as Wuhan, Xiantao, and Qianjiang in Hubei Province are projected to face more frequent and severe extreme rainfall episodes as the century progresses. [ABSTRACT FROM AUTHOR]

The thermal and dynamic effects of the special topography of the Qinghai–Tibet Plateau have a significant impact on rainfall in China. Utilizing NCEP/NCAR monthly reanalysis data alongside precipitation observations from 1936 monitoring stations across China spanning from 1966 to 2022, this study establishes a location index for the thermal low-pressure center situated over the Qinghai–Tibet Plateau. Temporal variations in the location index and summer (July) precipitation patterns in China were studied. Over the past six decades, thermal low-pressure centers have been predominantly positioned near 90° E and 32.5° N within a geopotential height of 4360 gpm, with their distribution extending from east to west rather than from south to north. The longitudinal and latitudinal position indices showed the same linear trend, with a negative trend before the 21st century, and then began to turn positive. Mutation analysis highlights pronounced weakening mutations occurring in 1981 and 1973, with the longitudinal index transitioning from an interannual cycle of approximately 6–8 years, while the latitudinal index displays quasi-cyclic oscillations of 5 and 8 and 12–14 years. Strong negative correlations are evident between the location indices and precipitation along the southeastern edge of the Qinghai–Tibet Plateau and in southern China, contrasting with the positive correlations observed in the central-eastern plateau, northwest, north, and the Huang-Huai region of China. The center of the thermal low is located to the east and north, corresponding to the deeper surface thermal low in most areas east of China, and the stronger transport of warm and wet air from the southwest wind, leading to greater convergence of southwest wind and northwest wind in China's northern region. The south of the Yangtze River is controlled by the strengthening West Pacific subtropical high and South Asia high, resulting in a significant decrease in precipitation, and the warm and humid air from the southwest on the west side of the West Pacific subtropical high is also transported to the north, increasing the precipitation in most parts of the north.

A comprehensive analysis of regional climate changes is essential in arid and semi-arid regions to optimize water resources management. This research aims to evaluate the changes in temperature and precipitation across the Mujib Basin in Jordan, using the most recent Coupled Model Inter-comparison Project Phase 6 (CMIP6) model. Firstly, the performance of six CMIP6 general circulation models (GCMs) to reproduce historical temperature and precipitation from 1985 to 2014 was evaluated using observed climate data. The most suitable GCM was then bias-corrected using the linear scaling approach. The findings demonstrate that the EC-Earth3–Veg model could reasonably simulate the historical climate pattern of the Mujib Basin, with coefficient of determination (R2) values of 0.90, 0.83, and 0.65 for monthly Tmin, Tmax, and precipitation, respectively. Under both the SSP2-4.5 and SSP5-8.5 scenarios, Tmax is projected to increase by 1.4 to 3.9 °C and 1.6 to 6.8 °C, respectively, whereas Tmin increases from 1.4 to 3.4 °C and 1.6 to 6.4 °C. Furthermore, precipitation is projected to decrease by 4.61–23.2% at the end of the 21st century. These findings could help policymakers in formulating better adaptation strategies to reduce the impact of climate change in Jordan This is a crucial step toward becoming a climate-resilient nation.

The ageing of the population is one of the most significant social transformations that the twenty first century is showcasing and a challenge that impacts society at large. The elderly, inasmuch as everybody else, are confronted with continuous transformations that are induced by technology, although they seldom benefit from the opportunities that technology entails. The digital divide amongst various segments of the population is often age-related and due to different reasons, including biological, psychological, social and financial ones. There is an ongoing reflection pertaining to the factors that hinders the full adoption of ICTs by the elderly and a question regarding what can be done to overcome their poor involvement in technology. This article, based on the results of a recent research, which has been conducted in Italy, aims at highlighting the importance of engaging the elderly in the use of technology as a key to building bridges between generations.

There is currently a certain pressure from various mnemonic communities, animated by vernacular interests, to canonize new saints within what is regarded as the flawed saints' cultural-political movement. Among these new, uncanonized saints, whose memory is commemorated unofficially in various cultural-political registers, there is also the football star Diego Armando Maradona, called by his millions of fans "the Hand of God" (La Mano de Dios). The commemorative culture that thrived around Maradona's persona—materialized in artefacts, shrines, icon-like paintings, prints, graffiti, stencils, and other memorabilia—do not fit the customary narratives of sainthood, nor to the display and content of the recently inaugurated (2023) memorial to the new martyrs of both the 20th and 21st centuries at Saint Bartholomew Basilica in Rome. The article argues that the commemoration of Maradona by his fans in Italy, Argentina, and worldwide is enacted in pop culture formats aimed at addressing different sets of contemporary mnemonic and spiritual needs. The aim is to offer a fresh conceptual engagement with the contemporary cultural-political phenomenon of "flawed saints" commemoration through the lens of contemporary popular culture, taking the culture of commemoration of Diego Maradona as a case study.

This article examines centenarian memoirs as a popular cultural phenomenon and through it the promises of post-reform vernacular history. The argument posits that these memoirs are a genre that has been commercially successful through their transformation of self and historical narratives in the People's Republic of China, in particular, the transformation of these memoirs from vestiges of state-cultivated intellectual confessions to vernacular cultural memories in the popular print market. Focusing on celebrated centenary memoir writers centring on Yang Jiang, the study develops Chen Sihe's conception of the vernacular, emphasising its shifting intersection with the political–institutional and the intellectual elite. The popular historiography emerging from these trans-generational memory "fevers" reveals vanishing modern Chinese intellectual values percolating through the vernacular ethos in the cultural industries of the early twenty-first century. The vernacular has been the post-reform locus for contesting and retaining critical intellectual traditions. [ABSTRACT FROM AUTHOR]

Numerous studies have investigated the long-term variability in surface solar radiation (SSR) around the world. However, the large disparity in the availability of observational data between developed and less developed/developing countries leads to an under-representation of studies on SSR changes in the latter. This is especially true for South America, where few observational studies have investigated the SSR trends and usually only at a local or regional scale. In this study we use data from 34 stations distributed throughout all of the regions of Brazil to present the SSR trends in the first 2 decades of the 21st century and investigate their associated causes. The stations were grouped into eight composites according to their proximity. Our results show that in north and northeast Brazil a strong dimming occurred, with significant contributions from increasing atmospheric absorption, most likely due to anthropogenic emissions, and increasing cloud cover. In the southeast and midwest regions of Brazil, near-zero trends resulted from competing effects of clear-sky processes (attenuation of solar radiation under cloudless conditions) and strong negative trends in cloud cover. In the southern part of the Amazon and in south Brazil a statistically insignificant brightening was observed, with significant contributions from decreasing biomass burning emissions in the former and competing minor contributions in the latter. These results can help deepen our knowledge and understanding of SSR long-term trends and their causes in South America, reducing the under-representation of this continent when compared with regions like Europe.

Organized immaturity, the reduction of individual capacities for public use of reason constrained by sociotechnological systems, constitutes a significant pushback against the project of Enlightenment. Forms of immaturity have long been a concern for philosophers and social theorists, such as Kant, Arendt, Fromm, Marcuse, and Foucault. Recently, Zuboff's concept of "surveillance capitalism" describes how advancements in digital technologies lead to new, increasingly sophisticated forms of organized immaturity in democratic societies. We discuss how sociotechnological systems initially designed to meet human needs can inhibit the multidimensional development of individuals as mature citizens. To counteract these trends, we suggest two mechanisms: disorganizing immaturity as a way to safeguard individuals' and collectives' negative freedoms (freedoms from), and organizing maturity as a way to strengthen positive freedoms (freedoms to). Finally, we provide an outlook on the five further articles that constitute the Business Ethics Quarterly Special Issue "Sociotechnological Conditions of Organized Immaturity in the Twenty-First Century."

The article is a book review of "The Case Study in Social Research: History, Methods, and Applications" by Barbara Sena. The review discusses the ambiguity surrounding the term "case study" and the need for methodological awareness when using this approach. The book provides comprehensive answers to questions about case studies, including its definition, differences from other research approaches, and its links to quantitative, qualitative, and mixed methods. The review praises the book for its accessibility and its ability to clarify and provide guidance on case study research. [Extracted from the article]

There is less consensus on whether human activities have significantly altered tropical cyclone (TC) statistics, given the relatively short duration of reliable observed records. Understanding and projecting TC frequency change is more challenging in certain coastal regions with lower TC activity yet high exposure, such as Western Europe. Here, we show, with large-ensemble simulations, that the observed increase in TC frequency near Western Europe from 1966 to 2020 is likely linked to the anthropogenic aerosol effect. Under a future scenario featuring regionally controlled aerosol emissions and substantially increased greenhouse gas concentrations (Shared Socioeconomic Pathway 5-85), our simulations show a potential decrease in TC frequency near Western Europe by the end of the 21st century. These contrasting trends in historical and future TC frequencies are primarily due to the rise for 1966–2020 and potentially subsequent fall for 2030–2100 in TC genesis frequency in the North Atlantic. The response of large-scale environmental conditions to anthropogenic forcing is found to be crucial in explaining the historical and future changes in TC frequency near Western Europe.

The establishment and maintenance of an effective democracy, characterized by its popularity, representativeness, and accountability, are fundamental elements in the process of consolidating a republic. Despite inherent challenges, such as antidemocratic coups that have left their mark on the country, perpetuating the use of force, it is imperative to chart a course toward democratic stability. The evolving definition of democracy over the years has given rise to diverse perspectives in the 21st century, emanating from individuals, institutions, and nations. Ecuador, as a republic, has experienced fluctuations in democratic stability throughout its history. This study focuses on analyzing the levels of democratic stability in Ecuadorian society, employing neutrosophic statistics to address the variability of the variable in question. The research results underscore that the deterioration of civil rights, evaluated from a neutrosophic perspective, emerges as a critical factor in the stability of democracy in society.

Extractivist archaeological practices have been carried out in the Atacama Lickanantay territory, Antofagasta region, northern Chile, ever since the 19th century, excluding or denying the voice and/or participation of members of the local indigenous community. However, the beginning of the 21st century saw a change in this sense bringing new experiences of collaboration between Atacameños and archaeologists. Our goal is to reflect on the definitions and applications of collaborative methodologies in archaeological projects, through discussion focusing on the global, through the national and finally the local, from where we approach a particular collaborative project. The research, conducted between early 2021 and mid 2024, studies the history of the collection and patrimonialization of indigenous bodies in the Atacameño Lickanantay territory, and socializes this information among the local communities. Based on this work, we conclude that all research in the territory must involve and be authorized by the Atacameño communities. Also, we consider that the Atacameños should stop being the object of research and instead become researchers who lead or collaborate in the studies within their communities and in their territory. The originality of this paper lies precisely in the fact that it brings a global discussion of contemporary archaeology to a concrete case. [ABSTRACT FROM AUTHOR]

This article analyses a series of articles published in Portuguese and Indian newspapers concerning the business trips of Portuguese Prime Minister António Costa to India in January 2017 and December 2019. It aims to scrutinise how, on the one hand, India and his Prime Minister, Narendra Modi, are presented in the Portuguese press and, on the other, how Portugal and António Costa are portrayed in the Indian press. What are the media frameworks and the language used by political actors and journalists during these trips? What are the affinities and the contrasts in the texts which circulate in the printed press in the colonial and in post-colonial periods? Does the coverage in the Portuguese and Indian presses at the beginning of the 21st century give us any indication of some post-colonial resentment in the current relations between India and Portugal? Or are commercial and technological interests overshadowing this past of Portuguese imperial rule in the Indian subcontinent? [ABSTRACT FROM AUTHOR]
