How will permafrost carbon respond to future climate change? A new assessment for future thaw trends of permafrost carbon on the Tibetan Plateau

Permafrost degradation on the Tibetan Plateau (TP) is anticipated to result in the thaw of permafrost carbon. Existing studies have been conducted to assess the future thaw of frozen carbon on the TP, primarily focusing on the deepening of the active layer while neglecting the impact of permafrost area shrinkage. This oversight may lead to a significant underestimation of the potential thaw of frozen carbon. Our research underscores the pivotal role of permafrost area shrinkage in estimating the future thaw of frozen carbon. Our findings reveal that when the combined effects of permafrost area shrinkage and active layer deepening are considered, the thaw rates of frozen carbon in various radiative forcing scenarios are nearly four times those based on active layer deepening alone. Notably, our results demonstrate substantial thaw of frozen organic carbon in the TP permafrost area under all four future scenarios: In the low radiative forcing scenario SSP1-2.6, it is predicted that 55.4 % of the organic carbon in the permafrost area 0–10 m soils will be in a state of thaw by 2100, and more than 90 % in the high radiative forcing scenario SSP5-8.5. This substantial thaw is poised to diminish the TP's current carbon sink function significantly. Our study emphasizes that as global warming persists, frozen carbon in permafrost areas will play a more active role in global carbon cycle processes in the future. Furthermore, we stress the importance of considering permafrost area shrinkage in understanding the thaw of frozen carbon, providing valuable insights for carbon balance studies on the TP.

An Analysis of Trade Protectionism from the Perspective of the Community of Human Destiny

With the continuous advancement of the process of trade globalization, free trade has become the dominant form of today's world economic system. However, it cannot be ignored that trade protectionism still exists and has gradually risen in recent years. The rise of trade protectionism, to a certain extent, has caused disorder in the international trade order and intensified trade frictions between countries, which fundamentally violates the objective law of the development of global economic integration. As a big country with a sense of responsibility, it is necessary for China to put forward China's plan to guide and resolve this problem in a targeted way from the perspective of the community of human destiny.

Changes in public interest in sudden cardiac arrest: a big data analysis

Abstract Background Search engine queries (SEQ) are considered a surrogate for public interest, with the most popular global search engine processing ~ 1.2 trillion online queries annually and >1 billion health-related queries daily.1 Big data from SEQ trends have been used for disease surveillance and may be able to offer insights for public health interventions, such as detecting respiratory illness outbreaks and understanding cardiac disease patterns.2-4 Sudden cardiac arrest (SCA) occurs in ~5 million people annually worldwide; October is internationally designated for SCA awareness, with public health campaigns aimed to improve early recognition of and early defibrillation for SCA. Use of big data from SEQ as a public health tool to assess changes in public interest surrounding SCA campaigns has not been explored. Purpose To characterize changes in public interest in SCA via analysis of internet SEQ trends. Methods Google Trends was queried for the terms "cardiac arrest", "cardiopulmonary resuscitation" (CPR), "automated external defibrillation" (AED) and "myocardial infarction" (MI) worldwide for the past 5 years (11/2018 – 11/2023). Relative search volumes (RSV, expressed in scale from 0-100) and related queries were analyzed. Baseline RSV for each term was defined as 2 weeks pre-peak. Numerical percentage and Chi square tests were used for statistical comparison. Results Compared to baseline, RSV for "cardiac arrest" significantly increased in correlation with the SCA of 2 professional athletes: Christian Eriksen (football, Denmark) on 6/12/2021 (+321%, p<0.001), Damar Hamlin (American football, United States) on 1/2/2023 (+653%, p<0.001) and collegiate athlete Bronny James (basketball, United States) on 7/24/2023 (+164%, p<0.001). (Figure) RSV significantly increased for "cardiopulmonary resuscitation" (+61% and +170% respectively, p<0.001 for both) and "Automated external defibrillator" (+141% and +192% p<0.001 and p=0.003, respectively) during the same period for pro-athletes but not for the college athlete (p=1.0 and p= 0.84 respectively). While none of the athletes had MI, RSV for "myocardial infarction" also had correlating increases over baseline for all 3 athletes (+35%, p<0.001 +30%, p<0.001 and +22%, p=0.027, respectively). RSV did not significantly change for any search terms during October SCA awareness months during the study period (all p>0.05). Conclusions Public interest in SCA, CPR and AED surge when SCA occurs in well-known individuals such as athletes, rather than with scheduled public health campaigns; co-surge in MI interest likely indicates on-going public confusion between SCA and MI. Analyses of big data from SEQ could assist cardiovascular societies in planning targeted SCA educational campaigns by building upon periodic natural surges in public interest in SCA, CPR and AED; this should include continued education on the differences in recognition and treatment of SCA and MI.

The ALMA-QUARKS Survey. II. The ACA 1.3 mm Continuum Source Catalog and the Assembly of Dense Gas in Massive Star-Forming Clumps

Leveraging the high resolution, sensitivity, and wide frequency coverage of the Atacama Large Millimeter/submillimeter Array (ALMA), the QUARKS survey, standing for “Querying Underlying mechanisms of massive star formation with ALMA-Resolved gas Kinematics and Structures”, is observing 139 massive star-forming clumps at ALMA Band 6 (λ ∼ 1.3 mm). This paper introduces the Atacama Compact Array (ACA) 7 m data of the QUARKS survey, describing the ACA observations and data reduction. Combining multi-wavelength data, we provide the first edition of QUARKS atlas, offering insights into the multiscale and multiphase interstellar medium in high-mass star formation. The ACA 1.3 mm catalog includes 207 continuum sources that are called ACA sources. Their gas kinetic temperatures are estimated using three formaldehyde transitions with a non-LTE radiation transfer model, and the mass and density are derived from a dust emission model. The ACA sources are massive (16–84 percentile values of 6–160 M ⊙), gravity-dominated (M ∝ R 1.1) fragments within massive clumps, with supersonic turbulence ( M>1 ) and embedded star-forming protoclusters. We find a linear correlation between the masses of the fragments and the massive clumps, with a ratio of 6% between the two. When considering fragments as representative of dense gas, the ratio indicates a dense gas fraction (DGF) of 6%, although with a wide scatter ranging from 1% to 10%. If we consider the QUARKS massive clumps to be what is observed at various scales, then the size-independent DGF indicates a self-similar fragmentation or collapsing mode in protocluster formation. With the ACA data over four orders of magnitude of luminosity-to-mass ratio (L/M), we find that the DGF increases significantly with L/M, which indicates clump evolutionary stage. We observed a limited fragmentation at the subclump scale, which can be explained by a dynamic global collapse process.

Regionalizing the supply chain in process life cycle inventory with multiregional input–output data: An implementation for ecoinvent with EXIOBASE

AbstractLife cycle inventory (LCI) databases, such as ecoinvent, are crucial for life cycle assessment (LCA), but lack country‐specific resolution in activity details and trade between regional activities in the supply chain. For example, ecoinvent only provides rest‐of‐world and European datasets for photovoltaic panel production, consuming the same global consumption mix of photovoltaic cells. Global or continental activities and trade limit the use of existing country activities, such as electricity production, and the accuracy and granularity of LCA results. We addressed this issue by disaggregating ecoinvent's global and continental unit processes to the country level and by regionalizing trade using country‐sector‐specific consumption mixes of product origins from the multiregional input–output table EXIOBASE. This produced a consistently regionalized ecoinvent at country level. Comparing the climate change impacts of 195,708 non‐market datasets in our regionalized ecoinvent with reference datasets in ecoinvent reveals manufacturing sectors as the most affected. The study of photovoltaic panel production shows that the differences in climate change impacts are mainly due to the different country‐specific suppliers of components and their electricity mixes, which are lost in the aggregated original data. The water consumption impacts of wheat production show the country differences only when regionalized CFs are applied, indicating that regionalized biosphere and technosphere flow amounts are needed for better results. The mapping quality between ecoinvent and EXIOBASE and inconsistent market definitions were discussed along with further limitations. Our study highlights the potential of incorporating better trade information and regional disaggregation in LCI databases to improve the LCA outcomes.

A comprehensive review on fresh and rheological properties of 3D printable cementitious composites

The undeniable potential of 3D printing technology to revolutionize global manufacturing processes has led to the emergence of advanced, digitalized, and fully automated construction techniques. Despite the growing interest in this technology, a significant challenge still exists in the development of cement-based printing material due to the complex interaction of various fresh and rheological property parameters. This review comprehensively explores fundamental fresh properties (flowability, buildability, extrudability, pumpability and open time) and rheological properties (static yield stress, dynamic yield stress, plastic viscosity) essential for the formulation of 3D printable cementitious composites, with and without fibres. The results obtained from different rheometers for successful 3D printed mixes are also summarized, highlighting variation in recorded values. Moreover, the review thoroughly investigates factors affecting both fresh and rheological properties, such as the type of supplementary cementitious materials, fibre type and dosage, superplasticizer, and viscosity-modifying admixture. It also identifies the clear impact of these parameters and further recommends the optimal range of some properties, such as a flowability value between 160 and 200 mm, to achieve desirable 3D printability of cementitious composites. Overall, this review offers valuable insights for developing new mix compositions suitable for 3D printing and serves as a useful tool in establishing guidelines for 3D printable cementitious composite materials, which are currently lacking but crucial for research, development, and application in this field.

Has process hijacked purpose? Outlook on food systems transformation in the global climate change processes

There has been growing interest in the Conference of Parties (COPs) meetings of the United Nations Framework Convention on Climate Change (UNFCCC) in food systems, which account for a third of global emissions and are heavily impacted by climate change. While there has been much rhetoric about the need for transformation at recent COPs, we examine whether this solely remains at the level of rhetoric and ambition or is likely to deliver the climate action that is needed. Based on literature, documentation of UNFCCC meetings, and our own participation, we observe that progress in the past on agriculture has been extremely slow and has led to limited action, while the recent verbiage on food systems has not been matched by significant progress in the negotiations. The urgent action needed is not realised through the UNFCCC processes. New and radically different ways to catalyse action are needed, and the UNFCCC process urgently needs reform as part of wider multilateral reforms. We propose that the scale of the COPs is reduced and that the focus shifts to the results delivered through rigorous evaluation, accountability and transparency, and a shift towards less consensus-based approaches to drive action and ambition.

L1 Education in Times of Globalization, Digitalization and Super-Diversity

This introduction first briefly sketches the (history of the) International Mother Tongue Education Network (IMEN). IMEN was founded in 1981 as an information and research network that over the years initiated an empirical-interpretive research program focusing on comparative analyses of the rhetoric and practices of L1 education across a dozen of European countries. Main elements of IMEN’s methodology that will be discussed below were the development of different types of research collaboration, a theoretical framework for comparative analysis, and a method for international triangulation. It then describes how, at the turn of the century, IMEN’s way of doing slow science became increasingly threatened by the requirements of publish or perish mainstream research, and how its research program was confronted with the challenges posed to L1 education by processes of globalization, digitalization, and super-diversity, becoming manifest in the superdiverse nature of student bodies, their sociolinguistic and ethnocultural doings, and the increasingly digitalized modes of teaching and learning they are exposed to. All these elements, in one way or another, also have an impact on the teaching-learning practices in mainstream L1 education and consequently must be addressed by IMEN-like studies. Finally this contribution briefly introduces the contributions to this special issue and suggests that they are a strong argument for a renewed interest in international comparative discussion on and around L1 education and a plea to further collaborative research from an empirical interpretive ethnographic perspective on teachers’ professional practical knowledge and classroom practices that can guide our understanding of the ubiquitous school subject L1 education that aims at preparing students for a global, digital, and super-diverse society.

Tenacity Besides Depletion: Pandemics, Protests, and Workers from the Sri Lankan Apparel Sector

AbstractSri Lankan apparel has conventionally crafted itself as a niche and ethical supplier. Staying with this record, shifting to PPE (personal protective equipment) production, a tripartite agreement on minimum wages and a furlough scheme were key successes during the pandemic. However, the recurrent absence of living wages resulted in varied worker experiences. I use written testimonies from women garment workers to raise pivotal questions on how the lives of workers started to deplete during the pandemic and yet it did not prevent women workers from claiming differently—underlining slivers of hope, where depletion and tenacity are constant bedfellows. The pandemic was when Sri Lankan apparel's dis/articulation within global production processes came about. Contributing to feminist political economy readings of global production processes, I illustrate how depletion and tenacity are no binaries; acknowledging these spaces of hope offers the potential for agentive action.

The impact of radio on the construction of smart cities

In the process of smart cities, radio technology has played an increasingly important role. With the continuous acceleration of the global urbanization process, cities are facing many challenges. Driven by the governments vigorous support and business promotion, wireless communication technology has developed rapidly, and new wireless communication technology has continued to emerge, providing more choices and possibilities for smart city construction. This article reviews and analyzes the actual case analysis, studies the impact of radio technology on the construction of smart cities, while explaining the importance of radio security management. The results showed that the application of radio technology enabled smart cities to achieve functions such as intelligent traffic management, intelligent communication, and intelligent energy management, but there were also problems such as leakage privacy, signal interference, and imbalance in regional development. In the process of future smart city construction, it is necessary to further optimize the safety and popularity of radio, promote the use of radio, narrow the gap between the use of different regions and cities, and enhance the radio management, so that it can better serve the construction of smart cities.

The article is based on the system of professional training of future teachers in higher educational institutions of the country. Today, an independent country is a country that determines the possibilities of future development, taking into account modern processes, technologies that provide its own system, model and quality of national education. Kazakhstan as a sovereign state, the signing of the Lisbon Declaration and participation in the Bologna process, etc. reflect its place in the global educational space. This circumstance contributes to the intensive development of the higher education system, taking into account the socio-cultural interests of our state and global educational processes that determine the quality and technological achievements in higher education. It is obvious that one of the urgent problems of pedagogical science and best practices is to identify priority areas for improving the upbringing and education of the free generation that has crossed the threshold of the XXI century. In the system of professional training of future teachers, their qualitative skills should correspond to social processes. Due to the transition of an independent country to a market economy in accordance with the changing requirements of the time, the main criteria of competitiveness oblige future teachers to have modern qualities along with knowledge, knowledge, business skills. In this regard, the article formulates the relevance and positions, features and rationality of the development of qualitative skills in the system of professional training of future teachers based on scientific analysis.

Current sports safety problems in Ukraine and the world

The article is devoted to the analysis and assessment of current problems and challenges faced by sports in Ukraine and the world, in connection with global crisis processes that lead to profound social changes. In recent years, the issue of sports safety in the world has become more relevant against the background of the COVID-19 pandemic, and in Ukraine due to military operations on its territory. Thus, security protocols are gradually undergoing changes and actions to ensure security of various levels are adapted to modern conditions. Safety instructions for mass sports events of various levels, orders of specialized services and ministries of various countries regarding the organization of events on their territory, government resolutions and laws regulating the safety of athletes, spectators and sports facilities were analyzed. Globalization processes are rapidly changing, which requires quick solutions without losing their quality. The topic of sports safety has become more relevant in recent decades. Sport is a global phenomenon that unites representatives of all social groups and strata. Although the official slogan of the international sports movement, which is supported by all its members, is: "Sports outside of politics", but at the same time, it is a powerful means of political influence and manipulation. History has seen many boycotts driven by political decisions in response to wrongful or military actions by one party against another. Everyone remembers the terrorist attacks committed at the Olympic Games and other international competitions. All this led to the intensification of the development of research in the field of sports safety. At the same time, sports competitions, especially international ones, attract the attention of a large number of spectators, which causes the desire of world political leaders, public figures, representatives of culture and art, etc. to participate in them.The study showed that the process of adaptation and response is imperfect and requires careful study and analysis, which determines the relevance of the topic.

The trend of “films as tourism promotion”: from picturesque landscapes to eco-consciousness in Vietnamese masses

Along with the intense globalisation process in Vietnam since the early 21st century, there has been a bloom of commercial films shot in the famous places of this country named ‘films as tourism promotion’. However, behind the eye-catching frames, the picturesque landscape, and the smooth cinematography, whether those films accompany the ecological discourse of preserving the indigenous natural environment is another complicated problem that needs to be challenged in this research. Since then, we will consider the effects of socialist nationalism and capitalism’s mass production on the eco-consciousness of the film audiences/masses, how they give the viewers a firm belief in the indestructible and sustainable beauty of the national landscapes, and how they distract the audience’s visual interest from practical issues. Also, we aim to examine the ecological status of these tourist sites after the movies were released to determine the chain-related environmental consequences of this cinematic trend.

Timing and pattern of the Devonian Nehden event: Implication for the biotic recovery following the F–F extinction event

The biotic recovery process following the Frasnian–Famennian (F–F) mass extinction played an important role in reestablishing the late Palaeozoic marine ecosystem. The Nehden event is assumed as the global biotic recovery process in the aftermath of the F–F mass extinction, but the timing and pattern of this event is still in dispute due to lack of consistent geological records. In order to recognize the Nehden event and elucidate its timing and pattern, a newly refined conodont biostratigraphic framework spanning the Palmatolepis minuta minuta Zone to the Pa. rhomboidea Zone (370.8–367 Ma) has been established in the Yangdi section, Guangxi, South China. Based on a detailed analysis of microfacies and carbon isotope of carbonates (δ13Ccarb), the start of the Nehden event has been placed at the upper part of the Pa. m. minuta Zone, marked by deposition of calcareous shales and proliferation of palmatolepid conodonts and ostracods. Two episodes of the Nehden event are recognized in this study according to integrated palaeontological, sedimentological, and geochemical data from South China and other continents. The first phase of the Nehden event is assigned at the upper part of the Pa. m. minuta Zone, characterized by radiation of conodonts, ostracods, and brachiopods, which is coincident with the minimum value of negative δ13Ccarb excursion and climate warming. The second phase is placed at the Pa. termini to Pa. glabra pectinata zones, documented by biodiversification of cheiloceratid ammonoids and phacopid trilobites, which is concurrent with climate warming and the maximum transgression during the early Famennian. The extensive development of microbial bindstone in the lower Famennian succession at Yangdi demonstrates that microbial communities occupied the vacant ecological niches left behind by metazoans after the F–F biotic crisis. The expansion of ecological niches of microbial communities and depauperation of metazoan reefs implies the bioconstructor turnover from metazoan to microbial communities following the F–F extinction. The time equivalence of biotic radiation, climate change and sea-level fluctuation in two episodes of the Nehden event indicates the early Famennian biotic recovery was favored by climate warming and transgression. The results in this study not only offer important data to constrain the timing of the Nehden event, but also provide an insight on the process of biotic recovery following the F–F mass extinction event.

EOR simulation of polymer flooding

Enhanced oil recovery (EOR) techniques, such as polymer flooding, have gained significant attention as a means to maximise hydrocarbon extraction from reservoirs. The success of polymer flooding is intricately tied to the complex interplay between fluid properties, reservoir heterogeneity, and injection strategies. It is admitted in classical modelling methodologies, to account for the mobility ratio in polymer flooding by scaling it with the help of the shear rate in situ. The accuracy of shear assessment therefore rules the mobility of oil and the global process efficiency. It is assumed to depend not solely on pore radius, rate, and porosity, but also on a dimensional parameter known as the shape factor, which varies according to the specifications of several authors. When lab measurement is available, it is possible to adjust this value to match the shear rate recorded from a rheometer at feeding stage, ahead of the core. In the present paper the consequence of not performing this stage in the case of a core flood, then in the simulation of a polymer flood pilot is investigated. An alteration of the recovery factor is then expected. The amplitude shall result from the coupling between pore-scale effects and reservoir-scale response, induced by geological constraints such as reservoir layers productivity, aquifer response, and multiphase dynamics. Relative effect and influence on reservoir parameters will be quantified, commented, and discussed.

Studying long term relationship between carbon Emissions, Soil, and climate Change: Insights from a global Earth modeling Framework

The persistent increase in greenhouse gas (GHG) emissions, notably carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), since the mid-20th century has been a key driver of significant climate alterations. This study investigates the complex feedback mechanisms that both influence and are influenced by global climate dynamics, soil processes, and GHG emissions. Our statistical approach incorporates correlation measures, highlighting the limitations of such analyses, namely their inability to confirm causality, sensitivity to outliers, and the exclusive capture of linear relationships. Geographically Weighted Regression (GWR) models reveal spatial variations in the relationship between environmental factors and GHGs, while Path Analysis aids in delineating direct and indirect influences among variables. The research pinpoints significant spatial heterogeneity in the impacts of economic and environmental factors on GHGs, underscoring the necessity of localized strategies for climate change mitigation and sustainable land management. This study also identifies potential threats to agricultural productivity due to soil degradation, which hinder climate adaptation efforts. Our findings advocate for a concerted global response to reduce GHG emissions and address the challenges posed by the interplay of climate change, soil dynamics, and GHG emissions.

The Role of Financial Instruments in Corporate Exchange Rate Risk Management

As international investment increases with the process of economic globalization, managing exchange rate risk efficiently has become one of the most significant strategies for companies to reduce risk and make more profits. Due to the need to consider numerous internal and external factors, risk management is a sophisticated decision that executives need to make effectively. On the basis of accentuating the magnitude of hedging exchange rate risk for corporations and combining previous research findings and theoretical analysis, this research introduces some pragmatic approaches for firms to choose and utilize suitable financial instruments in hedging exchange rate risk, such as the rational use of financial instruments to hedge risks, the use of short-term and long-term foreign currency derivatives to reduce exchange rate risks, and the impact of board structure on hedging activities. The content of the analysis can provide companies with a deeper understanding of the ways to select and utilize the most appropriate financial instruments for risk management, thus improving corporate efficiency and achieving corporate objectives. The study would act as an available tool for corporations to improve efficiency and achieve their goals.
