Toward sustainable development: Revealing the dynamic impacts of the belt and road initiative on energy transition

AbstractThis article investigates the influence of the belt and road initiative (BRI) on energy transition within the context of sustainable development goal (SDG) 7. The study utilizes daily data from May 3, 2017, to June 30, 2023, and deploys advanced econometric methods like heatmap‐based QVAR, cross‐quantilogram, and recursive time‐varying methods. The findings determine that BRI can significantly foster the global energy transition process. Further, the Paris Agreement (PA) and green finance (GF) support the energy transition system by showing positive effects. In contrast, geopolitical risk (GPR) introduces disruptive elements that impede green energy production. Notably, the amalgamation of GF, PA, and BRI showcases the potential to not only facilitate SDG 7 but also contribute substantially to SDGs 8 and 13. Based on the above findings, the study suggests fostering synergies and collaboration between GF, PA, and BRI to maximize their combined impact on the energy transition, which may decrease the influence of GPR.

ERS statement on transition of care in childhood interstitial lung diseases.

Interstitial lung diseases (ILD) are a heterogeneous group of rare diffuse diseases affecting the lung parenchyma in children and adults. Childhood interstitial lung diseases (chILD) are often diagnosed at very young age, affect the developing lung, and can have different presentations and prognosis compared to adult forms of these diseases. In addition, chILD in many cases may apparently remit, and have a better response to therapy and better prognosis than adult ILD. Many affected children will reach adulthood with minimal activity or clinical remission of the disease. They need continuing care and follow-up from childhood to adulthood if the disease persists and progresses over time, but also if they are asymptomatic and in full remission. Therefore, for every chILD patient an active transition process from paediatric to adult care should be guaranteed. This European Respiratory Society (ERS) statement provides a review of the literature and current practice concerning transition of care in chILD. It draws on work in existing transition care programmes in other chronic respiratory diseases, disease-overarching transition-of-care programmes, evidence on the impact of these programmes on clinical outcomes, current evidence regarding long-term remission of chILD as well as the lack of harmonisation between the current adult ILD and chILD classifications impacting on transition of care. While the transition system is well established in several chronic diseases, such as cystic fibrosis or diabetes mellitus, we could not find sufficient published evidence on transition systems in chILD. This statement summarises current knowledge, but cannot yet provide evidence-based recommendations for clinical practice.

Empowering Saudi Women through Automobile Advertisements: A Transitivity Analysis

The purpose of the present study is to examine automobile advertisements that specifically targeted Saudi women during the year the ban on women driving was lifted. The study employed a critical discourse analysis (CDA) focusing on Halliday's transitivity system to identify the transitivity processes of automobile advertisements. To discern the transitivity processes used, a combination of qualitative and quantitative methods were utilized to attain a comprehensive understanding of the various types of transitivity processes and the identifying themes promoted by these processes. The findings reveal that the material process was the most frequent process used in automobile advertisements targeting Saudi women, followed by the existential and relational processes. In addition, these processes were mainly employed to empower Saudi women, which is the primary theme identified during the qualitative analysis. Examining the roles and circumstances of the participants could yield more relevant data for future research.

Bridging Meaning and Tradition: A Transitivity Examination of Makassar Aruk Texts in Wedding Discourse

This study delves into a comprehensive analysis of language structures within the aruk text. Employing a qualitative approach, the research focuses on a meticulous examination of the transitivity system. The findings reveal the existence of six distinct process types within each clause, intricately involving the relationships among participants and their respective circumstances. Notably, the study identifies consistent predicate patterns in the formation of aruk texts, particularly prevalent in the context of wedding expressions within the metafunction of the Makassar language. Furthermore, the research uncovers that the articulation of meaning, based on linguistic data, encompasses ideational, interpersonal, and textual dimensions. This multifaceted analysis enables a nuanced understanding of meaning, elucidating the metafunction of language through the exploration of words, phrases, and clauses pertaining to the speaker's conceptual domain.

Ecological discourse analysis and meaning interpretation of BBC news reports on 2019 Australian bushfires from the perspective of transitivity system

Abstract The unprecedented 2019/20 Australian bushfires prompted this paper to conduct a transitivity analysis on the top three processes (material, relational, and verbal) in selected BBC news reports. Guided by the ecological philosophical view of “harmony with diversity, interaction, and coexistence,” the research aims to interpret ecological meanings in the text and enhance people’s awareness of environment conservation. The findings reveal that these news reports predominantly utilized material and relational processes to depict the devastating impact of the Australian bushfires on wildlife, the efforts of firefighters, volunteer rescue missions for wildlife, and the roles of individuals involved. These reports also conveyed extensive ecological information, highlighting the ecological crisis arising from the fires, the threat to species diversity, and the active social responsibility of various stakeholders. This research contributes to a deeper understanding of the ecological implications of the Australian bushfires and encourages proactive ecological protection measures.

REVEALING RIDDLER'S IDEOLOGY IN THE BATMAN MOVIE: A TRANSITIVITY ANALYSIS

This study aims to describe the transitivity system in the text. The transitivity system is used to explain ideational metafunctions in the theory of Systemic Functional Linguistics proposed by Halliday (2014). The analysis in this study focuses on Riddler's utterances in the film The Batman in 2022. This study analyzes the processes and participants contained in the clauses in these utterances. Then, the results of these findings will be linked with power hierarchy theory to reveal Riddler's Ideology. This study uses a qualitative descriptive method to show the analysis results. This research data is obtained from the transitivity process from Riddler utterances, which consists of the process and participants. The results show that Riddler used all kind of transitivity process. He used mostly material, relational, and followed by other processes. By using the transitivity process, Riddler can decide which character has more power through participant in the process. He used it on himself and his friend such as Batman and his follower more frequently than the government or higher up he discussed or talked to. Therefore, it can be concluded the ideologies that Riddler inherits is anarchist which influenced by narcissism.

A reliable hybrid autoregressive integrated moving average and deep reinforcement machine learning strategy for resiliency enhancement in microgrid

Machine learning algorithms are crucial for energy transition and climate change system resilience. This paper presents the essential issue of improved microgrid resilience after catastrophes, with a focus on the Root Mean Square Error (RMSE) assessment metric. By using a Hybrid Autoregressive Integrated Moving Average- Deep Reinforcement Learning (HARIMA-DRL) based machine learning microgrid restoration method for post-disaster power recovery, resilience in the operation aspect is enhanced. The local power grid's resilience during a simulated disaster is examined using a quantitative resilience measure that is based on two significant quality functions. When the hybrid HARIMA-DRL model final resilience value is 3.07 %, 7.78 %, and 11.51 % higher for 5000, 8000, and 10000 training datasets, as compared to Convolutional Neural Network and Long-Short Term Memory (CNN-LSTM) and Gauss Reinforcement Memory (GRM). Simulation findings comparing the proposed HARIMA-DRL method to CNN-LSTM and GRM models trained on separate datasets show that the HARIMA-DRL enhances grid instantaneous and average resilience by 3.38 % over T1 and 4.96 % over T2. Flexible kernel settings and smooth nonlinear prediction behaviour allow the proposed HARIMA-DRL approach to provide the highest resilience enhancement and lowest prediction error.

Pediatric Urology Providers' Perceptions and Attitudes on Transitional Urologic Care in a Single-Payer Health Care System.

Advances in health care have improved outcomes for pediatric patients with congenital neurourological conditions, highlighting the need for an effective transition from pediatric to adult care. This study investigates Canada's transitional urologic care within its single-payer health care system, focusing on the active members of Pediatric Urologists of Canada and their practices, perceptions, and attitudes toward transitional urologic care. A survey was distributed to 35 Pediatric Urologists of Canada members from July 2023 to January 2024, which collected data on transitional care practices and available transitional urology clinics. It also focused on a service overview, covering aspects such as the responder's geographic and institutional affiliations, clinical practice characteristics involving transitional care, perceived challenges, and strategies for care enhancement. Nationwide engagement emphasized a commitment to improving transitional care, with a significant proportion of respondents (64%) having over 10 years of practice, reflecting substantial experience in addressing transitional care challenges. The survey identified 4 dedicated transitional care clinics, 3 of which are active, pointing to concerted efforts toward specialized service provision. The major challenges identified include the lack of adult transitional care initiatives and governmental support. Recommendations for improvement should focus on standardizing transition protocols and boosting patient education. The survey also underscored the necessity of protocolized care for spina bifida-neurogenic bladder and complex urogenital conditions. This study highlights the active efforts and existing challenges within Canada's transitional urologic care system, particularly emphasizing operational transitional care clinics as a crucial step forward in catering to transitioning patients' needs.

Model checking distributed temporal logic

Abstract The distributed temporal logic (DTL) is a logic for reasoning about temporal properties of distributed systems from the local point of view of the system’s agents, which are assumed to execute sequentially and to interact by means of synchronous event sharing. Different versions of DTL have been provided over the years for a number of different applications, reflecting different perspectives on how non-local information can be accessed by each agent. In this paper, we propose an automata-theoretic model checking algorithm for DTL. To this end, we propose a notion of distributed transition system that will be used to specify the system to be verified. The properties that the system should meet are specified in DTL. In order to capture the models of these properties, we propose the notions of generalized distributed Büchi automaton and of distributed Büchi automaton. With these concepts, we are able to adapt results from automata-theoretic approaches to model checking in LTL to the distributed case.

Nationwide Survey on Transitional Care for Patients With Childhood-Onset Cardiomyopathy in Japan.

Background: Individuals transitioning into adulthood require age-appropriate medical care and delegation of decision-making authority from their parents to the patients themselves. Although there have been multiple observational and interventional studies on transitional care for patients with congenital heart disease (CHD) in the cardiovascular field, transitional care specific to childhood-onset cardiomyopathy (CM) remains unaddressed. Methods and Results: A nationwide questionnaire-based survey was performed in the pediatric cardiology departments of 151 facilities in Japan. Responses were obtained from 100 (66%) facilities with low transfer rates (<5%) for childhood-onset CM cases. The comparison between CHD-transferring and non-CHD-transferring facilities revealed a significantly higher transfer rate (83.9%) for childhood-onset CM cases in the CHD-transferring facilities (P<0.001). Regarding the transition programs, 72 (72%) facilities do not offer any programs for CM, while most (92%) facilities recognize its necessity. Finally, only 19 (19%) facilities provided a transition program, 10 of which were CHD based. Conclusions: To the best of our knowledge, this is the first study to demonstrate the poor transition/transfer care status of patients with childhood-onset CM in Japan. The transfer rate of CMs was lower than that of CHDs, and transition programs were less available. Referring to the system established for CHD could help develop a successful transitional care system for CM.

Grammatical Metaphor in the C-E Translation of Jing Ye Si

In translation, translators are often confronted with the choice between congruent form and metaphorical form, which is closely correlated with grammatical metaphor theory in systemic functional linguistics. This paper attempts to apply grammatical metaphor theory to Jing Ye Si and its seven translations to assess poetry translation quality and provide guidance for translators from the perspective of systemic functional linguistics. It strives to elucidate the grammatical metaphor in the C-E translation of Jing Ye Si and the way to evaluate its seven translations via grammatical metaphor. In this context, six steps brought forward by Huang Guowen (2004) are taken in the functional discourse analysis of Jing Ye Si and its seven translations. After elaborating the characteristics of the seven translations, the study evaluates their overall translation quality. According to functional equivalence to the source text, the translations of Xu Yuanchong and Amy Lowell outperform other translations. In translation practice, translators are advised to choose between the congruent form and metaphorical form based on the context, original author, target readers, aesthetic value, translation purpose, and so on. Essentially, it is necessary to manipulate the transitivity system, mood system, modality system, and Theme system to realize the equivalence of the translations to the source text in terms of ideational, interpersonal, and textual metafunctions.

Formal Analysis and Detection for ROS2 Communication Security Vulnerability

Robotic systems have been widely used in various industries, so the security of communication between robots and their components has become an issue that needs to be focused on. As a framework for developing robotic systems, the security of ROS2 (Robot Operating System 2) can directly affect the security of the upper-level robotic systems. Therefore, it is a worthwhile research topic to detect and analyze the security of ROS2. In this study, we adopted a formal approach to analyze the security of the communication mechanism of ROS2. First, we used a state transition system to model the potential vulnerabilities of ROS2 based on the ROS2 communication mechanism and the basic process of penetration testing. Secondly, we introduced a CIA model based on the established vulnerability model and used linear temporal logic to define its security properties. Then, we designed and implemented a vulnerability detection tool for ROS2 applications based on the vulnerability model and security properties. Finally, we experimentally tested some ROS2-based applications, and the results show that ROS2 has vulnerabilities without additional protection safeguards.

An Analysis of Student’s Recount Text: An SFL Approach

This paper reports on the results of a study aiming to investigate the student’s ability to write recount text of a university student in Bandung. The study was conducted using the theory of Systemic Functional Linguistics (SFL), especially functional grammar, in terms of the Transitivity, Mood and Modality system. The study used a case study on text analysis. A text, which is a recount text written by a higher achiever university student, was analysed using the Transitivity, Mood and Modality system. In terms of the Transitivity system, the result indicates the writer’s adequate syntactic compression and rich lexico-grammatical patterns. Moreover, in terms of the Mood and Modality system, the text shows the writer’s ability to infuse, temper, negotiate, and constrain the experiential meanings in the Mood that is in focus. Hence, the writer is categorized as a mature and critical writer, and the text is appropriate to be used as a model text. Research on text analysis using SFL of different genres of text and how the teaching of writing should be conducted to help improve students’ writing ability is recommended.

Circular food system approaches can support current European protein intake levels while reducing land use and greenhouse gas emissions

Protein transition and circular food system transition are two proposed strategies for supporting food system sustainability. Here we model animal-sourced protein to plant-sourced protein ratios within a European circular food system, finding that maintaining the current animal–plant protein share while redesigning the system with circular principles resulted in the largest relative reduction of 44% in land use and 70% in greenhouse gas (GHG) emissions compared with the current food system. Shifting from a 60:40 to a 40:60 ratio of animal-sourced proteins to plant-sourced proteins yielded a 60% reduction in land use and an 81% GHG emission reduction, while supporting nutritionally adequate diets. Differences between current and recommended total protein intake did not substantially impact minimal land use and GHG emissions. Micronutrient inadequacies occurred with less than 18 g animal protein per capita per day. Redesigning the food system varied depending on whether land use or GHG emissions were reduced—highlighting the need for a food system approach when designing policies to enhance human and planetary health.

The Mass Dependence of Hα Emission and Stellar Spindown for Fully Convective M Dwarfs

Fully convective M dwarfs typically remain rapidly rotating and magnetically active for billions of years, followed by an abrupt and mass-dependent transition to slow rotation and quiescence. A robust understanding of this process is complicated by difficulties in estimating M dwarf ages and potential dependencies on other variables such as birth environment or metallicity. To isolate the effect of mass, we consider M dwarfs in wide binaries. We identify 67 widely separated, fully convective (0.08–0.35 M ⊙) M dwarf binary systems using Gaia and measure the Hα feature for each component. We classify the pairs into three categories: systems where both components are active, systems where both are inactive, and candidate transition systems, where one component is active and the other inactive. We gather higher-resolution spectra of the candidate transition systems to verify that their behavior does not result from an unresolved third component, yielding one new triple with surprising activity levels. Neglecting this triple, we find 22 active, 36 inactive, and eight transition pairs. Our results are consistent with the epoch of spindown for these binaries being primarily determined by mass, with mild second-order effects; we place a 1σ upper limit of 0.5 Gyr or 25% on the dispersion in the mass-dependent spindown relation. Our findings suggest that the large dispersion in the spindown epoch previously observed for field stars of a given mass may stem from differences in birth environment, in addition to modest intrinsic stochasticity. We also see evidence that the wide binary population is dispersed over time due to dynamical processing.

Learning to Execute Timed-Temporal-Logic Navigation Tasks under Input Constraints in Obstacle-Cluttered Environments

This study focuses on addressing the problem of motion planning within workspaces cluttered with obstacles while considering temporal and input constraints. These specifications can encapsulate intricate high-level objectives involving both temporal and spatial constraints. The existing literature lacks the ability to fulfill time specifications while simultaneously managing input-saturation constraints. The proposed approach introduces a hybrid three-component control algorithm designed to learn the safe execution of a high-level specification expressed as a timed temporal logic formula across predefined regions of interest in the workspace. The first component encompasses a motion controller enabling secure navigation within the minimum allowable time interval dictated by input constraints, facilitating the abstraction of the robot’s motion as a timed transition system between regions of interest. The second component utilizes formal verification and convex optimization techniques to derive an optimal high-level timed plan over the mentioned transition system, ensuring adherence to the agent’s specification. However, the necessary navigation times and associated costs among regions are initially unknown. Consequently, the algorithm’s third component iteratively adjusts the transition system and computes new plans as the agent navigates, acquiring updated information about required time intervals and associated navigation costs. The effectiveness of the proposed scheme is demonstrated through both simulation and experimental studies.

Exploring trade-offs between residential and industrial functions in rural areas and their ecological impacts across transitioning agricultural systems: Evidence from the metropolitan suburbs of China

The rapid transition of agricultural systems substantially affects residential and industrial land use systems in rural areas, often generating spatiotemporal trade-offs between residential and industrial functions and producing considerable ecological impacts, which has thus far not been well understood. We conduct an indicator-based assessment of transitioning agriculture systems, and then links the transitioning agricultural systems to trade-offs between residential and industrial functions from 2005 to 2020 by using a case study—the metropolitan suburbs of Beijing, China. Also, the associated ecological impacts of the trade-offs are characterized based on the calculation of the ecological quality index (EQI) and ecological contribution rate. The results show that trade-offs between residential and industrial functions in the metropolitan suburbs have gradually adapted to the different agricultural systems in transition, which can be characterized by increasing industrial function as well as declining residential function, together with the diversification of land use into a mixed pattern. Additionally, along with the transitioning process comes a U shape of the ecological quality curve, which indicates that relentless industrial sprawl into regions where the agricultural system has a low capacity for technology, as well as decay in rural areas attributed to a rural exodus and industrial decline in semi-subsistence agricultural areas, even cause ecological degradation. In general, trade-offs between residential and industrial functions (especially for the non-agricultural production function) in rural areas could partially and temporally generate unfavorable ecological impacts, but it seems to be a favorable phenomenon to promote ecological quality in the long term. Therefore, to achieve rural sustainable planning, it is necessary for land use management to observe the trade-offs between residential and industrial functions while avoiding negative impacts, such as low-density land use patterns, disordered land use functions, and eco-environmental deterioration. Such effective strategies can contribute to the feasible implementation of policies aiming to achieve the compatible development of liveable residences, highly efficient industrial production, and eco-friendly operations in rural areas.
