Published: February 2025

Abstract. Smartphone pressure observations have demonstrated significant potential to complement traditional pressure monitoring. However, challenges remain in correcting biases and further leveraging these observations for practical applications. In this study, we used tropical cyclones (TCs) Lekima in 2019, Hagupit in 2020 and In-fa in 2021 as examples to conduct bias correction on labeled smartphone pressure data from the Moji Weather app. We propose a quality control procedure utilizing random forest machine learning models. By applying this quality control approach to the selected TCs, we discovered that the performance of the method for labeled data significantly surpassed that for unlabeled data developed in a previous study, reducing the mean absolute error from 3.105 to 0.904 hPa. The bias-corrected smartphone data were then supplemented with weather station data for sea-level-pressure analyses and compared with the analyses that used only weather station data. The significantly higher spatial resolution and broader coverage of the smartphone data led to notable differences between the two analysis fields. Additionally, we compared the minimum sea-level pressure of TCs derived from smartphone data, weather station observations and the best-track dataset from the Shanghai Typhoon Institute (STI) of the China Meteorological Administration. We found that the best track published by STI consistently underestimated the minimum sea-level pressure, with a median difference of 0.51 hPa in the three TC cases.

Abstract. The full understanding of climate feedbacks responsible for the amplification of deglaciations requires robust chronologies for these climate transitions, but in the case of marine records, radiocarbon chronologies are possible only for the last glacial termination. Although the assumed relationships between the marine isotopic record and the orbital parameters provide a first-order chronology for glacial terminations, an independent chronological control allows the relationships between orbital forcing and the climate response to be evaluated over multiple previous terminations. To assess this, we present geochemical records from the western Mediterranean, including two speleothems and one marine sediment core. The most notable speleothem, the so-called RAT, established a new long terrestrial climate record for this region, spanning Marine Isotope Stages from MIS 11 to MIS 7. Its absolute U / Th dates provide an exceptional chronology for the glacial terminations IV, III, and III.a. The onset of these three glacial terminations was marked by rapid δ18O depletions, reflecting ocean freshening by ice melting, thus providing an excellent tie point for regional marine records also sensitive to such freshening. This is exemplified by new δ18O data of the Ocean Drilling Program (ODP) 977 site from the Alboran Sea, where the speleothem chronology was employed to adjust its age model. The new chronologies reveal an earlier onset of the deglacial melting for the TIV and TIII.a that is in contrast to the generally accepted marine chronologies and indicates that the duration of these deglaciations was variable, with TIV being particularly longer (∼ 20 kyr). This study also supports that the onset of deglacial melting always occurred during a declining precession index, while a nonunique relation occurred with the obliquity parameter.
La flecha y la trampa. Figuras de la finitud en un discurso fúnebre de Kierkegaard
Authors: Figueroa Weitzman Rodrigo , Mittelmann Jorge
Published: February 2025

Este artículo elabora la posición de Kierkegaard ante la muerte, tal como ella comparece en un escrito exhortativo inscrito en su colección de Discursos Edificantes. Se defiende la tesis que la posición original elaborada en este escrito a la vez (i) se inspira en el célebre argumento de Epicuro contra el temor a la muerte y (ii) refuta ese argumento mediante consideraciones que no invalidan su estructura deductiva, pero ponen de manifiesto su insuficiencia fenomenológica. El elemento central de esa refutación consiste en habilitar un modo de referencia al morir por medio del cual dicho acontecimiento se vuelve coextensivo a la existencia como un todo y abandona su locación temporal hipotética o remota. Dicha referencia es lo que Kierkegaard designa como “serio pensamiento de la muerte”, que logra sustraer el límite de la existencia a su doble condición periférica y anónima. Para Epicuro, la muerte es periférica en cuanto circunscribe la existencia sin formar parte de ella; y la muerte es anónima en cuanto sobreviene a la especie, o al individuo solamente en cuanto adscrito a ella. El antídoto de Kierkegaard contra Epicuro personaliza el morir y lo convierte en una inminencia contemporánea a cada instante.
Leibniz y el problema de la relación entre Dios y las esencias: oposición y evolución desde un modelo teo-mereológico hacia un modelo representacional
Authors: Silva Camilo
Published: February 2025

La presente contribución tiene por objeto examinar el problema de la relación entre las esencias y Dios en la metafísica de Leibniz, fundamentalmente a la luz de la oposición y evolución de dos modelos que dan cuenta de una transición significativa en su metafísica de las esencias, a saber, un modelo teo-mereológico según el cual las esencias constituyen la naturaleza ontológica de Dios y, en el límite, se identifican a él (1668 – 1676) y un modelo representacional que hace de las esencias objetos intencionales del entendimiento de Dios, sin que ellas constituyan propiamente, ni puedan identificarse a Dios ni a su entendimiento (1680 en adelante).
Por medio de un análisis de diversos manuscritos de Leibniz, así como una remisión a algunos estudios relativos a la ontología leibniziana de las esencias, nuestro propósito consiste, particularmente, en mostrar de qué manera y por qué el modelo teo-mereológico adoptado por el joven Leibniz es superado por un modelo representacional.

Los textos comerciales nos permiten adentrarnos en un género discursivo en desarrollo con una arquitectura textual y una expresión verbal particulares y caracterizadoras.
Estudio metapragmático de las percepciones de la cortesía en hablantes de español peninsular en dos generaciones
Authors: Hidalgo Downing Raquel
Published: February 2025

Los estudios sobre cortesía en español gozan de una sólida y nutrida tradición, en la que se han estudiado tanto los aspectos teóricos de la cortesía con propuestas específicas para la(s) cultura(s) hispánicas, como en aspectos descriptivos e interaccionistas, sobre los que la bibliografía es abundante (Iglesias Recuero, 2001). A partir de los estudios de Blum-Kulka (1992) y del trabajo de Eelin (2001), se pone de manifiesto la necesidad de estudiar la cortesía no solo en sus formulaciones lingüísticas (la denominada cortesía de segundo orden) sino también en las percepciones de la cortesía elaboradas por los hablantes (cortesía de primer orden). Este trabajo se inscribe en esta corriente, y propone indagar en la noción de cortesía común o lay politeness (Ogiermann y García-Conejos Blitvich, 2019) en un estudio inter-generacional, examinando cómo dos generaciones distintas abordan sus percepciones y conceptualizaciones de la cortesía en la vida cotidiana en la sociedad española actual, a partir del estudio del metalenguaje de la cortesía en los informantes, así como las asociaciones y sentidos que encuentran en los términos sometidos a estudio.
De la información a la (inter)acción: El papel de las interrogativas en el corpus GestINF
Authors: Rodríguez Rosique Susana
Published: February 2025

El propósito de este trabajo es destacar el papel de las interrogativas entre el conjunto de estrategias que emplean los hablantes para gestionar la configuración informativa que hay detrás de cada interacción. En este sentido, el trabajo parte de la función más inmediata de la interrogación —como manera de actualizar el archivo informativo que comparten los participantes en un acto comunicativo— para ir trazando un puente hacia otras categorías. Como evidencia, se toma el corpus interaccional GestINF como punto de partida. En términos generales, la interrogativa se perfila como una herramienta rentable para vehicular el tándem intersubjetividad / miratividad, que permite a los hablantes manejar la responsabilidad informativa o mostrar su reacción ante un determinado estado de cosas. Más allá, la interrogativa se convierte también en un mecanismo útil para la organización estructural de un determinado tipo de discurso.
Theme and Idea Directions of Joseph Heller's Novel “Something Happened”
Authors: Ahmadova Latifa
Published: February 2025

Joseph Heller was a significant writer who played an important role in the literary process of the United States in the second half of the 20th century. His novel Something Happened presents a remarkable example of black humor in American literature by addressing socio-political and socio-psychological issues against the backdrop of the tense events of its time. Due to the novel’s prolonged writing process—spanning over a decade—it was influenced by major political developments in the country and the world, particularly the Vietnam War (1955–1975). The novel elevates a typical representative of Heller’s contemporaries to an artistic level. It stands out for its satirical and ironic style. The plot does not follow a linear progression; the narrator constantly shifts between the past and the present, focusing on different subjects. The central moral-psychological theme of the novel is the "fear of losing everything." Heller expresses this fear through the style and tone of black humor. In Something Happened, Heller argues that human life is shaped by things we cannot face.
Keywords: Joseph Heller, Something Happened, American literature, black humor, fear.
The Influence of Cognitive Style on Abstraction Ability and Mathematical Problem-Solving in Problem-Based Learning

Published: February 2025

This article explores the influence of cognitive style on abstraction ability and mathematical problem-solving skills in Problem-Based Learning (PBL). Cognitive style, which reflects how individuals process and organize information, is hypothesized to play a significant role in determining students' success in understanding abstract concepts and solving mathematical problems. This study employs a quantitative method involving secondary-level students as participants. The research instruments include cognitive style tests, abstraction ability tests, and mathematical problem-solving tests. The results indicate that students with an analytical cognitive style tend to have higher abstraction abilities and better performance in mathematical problem-solving compared to those with a holistic cognitive style. These findings suggest that cognitive style influences the effectiveness of problem-based learning, particularly in subjects requiring logical and abstract thinking, such as mathematics. The implications of this research highlight the importance of educators recognizing and accommodating the diversity of students' cognitive styles when designing learning strategies. Furthermore, the study suggests the need to develop more flexible and inclusive learning approaches to maximize each student's learning potential. This article contributes to understanding how individual factors, such as cognitive style, can influence learning outcomes, particularly in the context of PBL.

BEYOND THE PROMOTION OF ECONOMIC COOPERATION: THE ECONOMIC COMMUNITY OF WEST AFRICAN STATES PEACEKEEPING INVOLVEMENTS IN WEST AFRICA
Authors: Okolie Ugo Chuks , ORHERO Ejogba Abraham
Published: February 2025

In order to raise the living standards of its people, maintain and improve economic stability, foster relations among Member States, and contribute to the advancement and development of the African continent, Economic Community of West African States (ECOWAS) was established. Its goal is to promote cooperation and integration that will result in the creation of an economic union in West Africa. According to a set of guiding principles, such as impartiality, the parties' consent, and the non-use of force unless necessary for self-defense, a third party intervention known as "peacekeeping" is conducted. The study examines the role played by ECOWAS in preserving stability and peace on the African continent, focusing in particular on the ECOMOG intervention in Liberia, Sierra Leone, and Guinea Bissau. The regional security complex theory was accepted. The research was qualitative, and its historical analysis heavily drew on secondary sources.  The essence of the resolutions of the UN Security Council and the ECOWAS Mediation and Security Council, and consequently the legal foundation for peacekeeping and peace enforcement are contained in peace agreements. As a result, peace agreements are essential to the management and resolution of conflicts. However, it is erroneous to assume that the heads of armed factions are sane political actors motivated by genuine grievances and that they will thereby agree to mediated agreements. The offering of carrots (the confidence-building approach) must therefore be combined with strong diplomacy supported by a credible enforcement capacity in order for peace to be successfully implemented in the West African region.  The study recommends, among other things, that the framework for the ECOWAS legal system governing peace and security should be the member states. This is because the majority of democracies in the sub-region elect postcolonial states with a predominance of coloniality of power disguising itself as democracy and causing conflicts in the majority of countries within the West African security complex, ECOWAS must exert pressure on its member states to step up their efforts to improve democracy in their respective countries.
Climate stress test of the global supply chain network: the case of river floods
Authors:   Bank of Greece, Papadopoulos Georgios , Ojea-Ferreiro Javier ,   Bank of Canada, Panzica Roberto ,   Bank of Portugal
Published: February 2025

This study investigates how extreme flood events can indirectly impact the global supply chain through production disruptions. Using a data-driven, agent-based network model that combines company-level data with flood hazard maps, the research simulates the transmission and amplification of shocks. The findings emphasize that the size of inventories is crucial; a lean-inventory system leads to faster shock propagation, higher losses, and fewer recoveries compared to an abundant-inventory system. Additionally, the study identifies that the number and criticality of flooded companies' trade links, along with the magnitude of the flood, correlate with the speed and severity of contagion. Interestingly, a key metric -the average criticality of affected firms' outgoing links- consistently peaks before the onset of the shock's fast-propagation regime. This could serve as an early warning indicator, giving businesses and policymakers precious time to react. By identifying these critical vulnerabilities, this research provides a framework for enhancing the resilience of global supply chains in the face of increasing climate-related and other risks.

Published: February 2025

Online learning has become more common since the COVID-19 pandemic, but limited research has examined factors affecting students' ability to transfer learning from online to the real world. This mixed-methods study explored the relationships between higher-order thinking skills, namely cognitive presence and self-regulation, and their roles in learning transfer in an online postgraduate medical sonography course in an Australian University. Performance data was evaluated for 53/54 students who allowed their online learning platform data, grades, and written contributions to learning tasks to be collected. Students also completed questionnaire measures of cognitive presence and online self-regulation, and seven students were interviewed about learning transfer. Cognitive presence and online self-regulation strategies were positively correlated. Interviews revealed that internal factors, such as cognitive presence and self-regulation, and external factors, such as supervisor support and workload, affected online learning transfer. Student performance indicated a high percentage of the Resolution phase of cognitive presence, which means near transfer. Our results suggest that cognitive presence and self-regulation can enhance students’ ability to transfer learning within and beyond the course. Despite the complexities in online pedagogy, educators should create online content to foster cognitive presence and self-regulation to enhance students’ ability to transfer learning to the real world.

Surrogate outcomes and fast-track drug approval
Authors: Saiz Fernández Luis Carlos
Published: February 2025

INTRODUCTION When investigating drug efficacy, surrogate variables are becoming increasingly important. They are simpler and quicker to obtain than clinical variables, but only indirectly related to the effect of interest. The aim of this bulletin is to describe and reflect on the implications of adopting surrogate endpoints and accelerated approval strategies in drug evaluation. METHODS A literature search was conducted on 30/04/2024 in MedLine, The Cochrane Library, websites of regulators and health technology assessment agencies, and other sources, focusing on the term ‘surrogate outcome’. CONCLUSIONS Surrogate outcomes require adequate validation to prove their usefulness. However, health authorities accept variables with progressively lower standards. Accelerated approvals require confirmatory studies that are often not completed. HIV viral load or blood pressure are examples of adequately validated variables. In contrast, inconsistencies are identified in variables used in the approach to cancer, dementia, osteoporosis and infectious or cardiovascular diseases. Premature access to pharmacological therapies may result in a higher incidence of adverse reactions with little scope for implementing harm mitigation strategies. The abandonment of clinical trials in favour of predictive or observational designs compromises the quality of the evidence obtained.

Authors: Wen Zhaolun
Published: February 2025

With the rapid development of China's economy and technology, infrastructure construction is developing rapidly, and the development of underground space is gradually developing in the direction of the depth of the stratum. The shield construction environment is becoming more and more complex, and the excavation face instability accidents caused by improper construction parameter settings occur from time to time. Once the excavation face of deep shield tunnel is unstable, it is difficult to carry out rapid rescue on site. Therefore, it is of great significance to study the influence of different factors on the stability of excavation face under deep buried conditions and to evaluate the risk of excavation face instability. The shield model machine can make on-site simulation experiments and give on-site opinions. The shield machine, the full name of the shield tunnel boring machine, is a kind of special engineering machinery for tunnel excavation. The modern shield tunnel boring machine integrates light, machine, electricity, liquid, sensor and information technology. It has the functions of excavating and cutting soil, conveying soil, assembling tunnel lining, measuring and guiding correction. It involves geology, civil engineering, machinery, mechanics, hydraulic, electrical, control, measurement and other multi-disciplinary technologies, and it is necessary to carry out ' tailored ' design and manufacture according to different geology, and the reliability requirements are extremely high. Shield tunneling machine has been widely used in subway, railway, highway, municipal, hydropower and other tunnel projects. The shield model machine is used to simulate the shield process of the shield machine and prevent dangerous situations during the shield process.
Geometric Parameter Evaluation of Oil and Gas Pipeline Defects Based on Deep Learning Neural Networks
Authors: Yan Kaiqi , Wu Wei , Wei Hangxin , Sun Jinghao
Published: February 2025

Pipeline magnetic flux leakage (MFL) detection technology has been widely used in online pipeline defect detection due to its advantages of not requiring coupling agents and being easily automated. Accurately predicting defect sizes based on detection data and conducting applicability evaluations are crucial for subsequent repair decisions. Based on the collected MFL data, a deep learning object detection model based on PP-YOLOE (Paddle Paddle - You Only Look Once Evolved) is proposed according to the characteristics of defect data. By converting MFL data into images and feeding them into the model for object detection training, defects can be quickly located and data extracted, providing an accurate and reliable dataset for defect quantification. The axial and radial MFL data of pipeline defects are used as inputs to the model, and the length, width, and depth of defects are output in parallel according to the characteristics of MFL data, thus achieving the assessment and prediction of defect sizes.

In this paper, the geometric nonlinearity and hydrodynamic characteristics of a long flexible viscoelastic riser under the interaction of internal and cross-flow velocity are presented. The system governing equation is obtained by using the extended Hamilton principle. The drag and lifting coefficients of coupled and distributed van der Pol wake oscillators are established to represent hydrodynamic of ocean currents. The effects of internal flow velocity, cross-flow velocity and viscoelastic coefficient on the stresses, displacements, natural frequency and mode variation of the pipeline are theoretically investigated. The results show that the cross-flow velocity, internal velocity and viscoelastic coefficient have important impacts on the vibration amplitude and critical internal fluid velocity of the riser. Additionally, the cross-flow velocity, internal fluid velocity and viscoelastic coefficient have vital effects on the riser mode order. Therefore, choosing the appropriate viscoelastic coefficient can reduce the vibration amplitudes of the riser. These findings have important reference value for the design and control of ocean riser.

A three-stage planetary gear reducer was designed for low-speed, heavy-load operating conditions, and a dynamic model was established after optimizing the load distribution through floating planet carriers. This model was used to study the nonlinear motion factors in the gear system, with a particular focus on the internal excitation caused by time-varying meshing stiffness. A mathematical analysis model of the mechanism was developed using MATLAB, and the time-varying meshing stiffness curves were derived. The analysis shows that the system exhibits periodic motion with changes in stiffness. Additionally, the load distribution of the system was analyzed based on stiffness variation, and the research indicates that as the stiffness increases, the transmission system experiences greater vibrations and impacts, leading to a decline in load distribution performance. Finally, a kinematic simulation model of the planetary gear system was established using ADAMS. Simulation results demonstrated that load distribution optimization for this transmission system is essential and provided the basis for this conclusion.
Exploring Feminist Ideology and Its Influence on Body Image in Chinese Social Media: A Content Analysis of Xiaohongshu Posts

Published: February 2025

While studies have been conducted to explore the role of culture, media influences, and social comparisons on body dissatisfaction, research on the relationship between feminist identity and body dissatisfaction is lacking. This paper aims to fill this research gap by focusing on Generation Z and Millennial women on the Chinese social platform Xiaohongshu and using content analysis to examine the association between feminist identity development and body dissatisfaction. Findings indicated that body dissatisfaction and feminist identity development were negatively correlated. Women in the Passive Acceptance stage were far more inclined to have body dissatisfaction, while those in the Embeddedness-Emanation, Synthesis, and Active Commitment stages had greater optimism about their bodies. Furthermore, to better understand the complexities of body dissatisfaction and to offer novel perspectives for the advancement of theory and practice in related fields, future research could examine the use of feminist theory in mental health interventions, policy development, and social change to enhance body image standards and encourage women's self-acceptance.

Authors: Liu Yuqing
Published: February 2025

This paper discusses the impact of artificial intelligence on employee performance, focusing on the analysis of the positive and negative effects of AI on employee performance in the work scene and some challenges through my hybrid analysis method that combines quantitative analysis and qualitative analysis. Through the review of secondary data and the collection of some primary data, an objective research methodology has been obtained. The research reveals the wide application of AI in employees and its limited impact on management decision-making. Although AI can improve employees' work efficiency, it still has limitations when dealing with some complex tasks. Similarly, this paper also discusses some policies and measures that may enable AI to better assist employees, aiming to promote the integration of AI and employee performance, emphasizing the importance of innovation management and employee adaptation to technological change. The research conclusion points out that the rational application of AI can not only improve the individual performance of employees, but also release the maximum potential of AI and employees through innovation motivation and team cooperation. However, future research should continue to focus on the evolution of AI in management and explore more balanced and humanized AI integration strategies to improve employee performance and organizational effectiveness, and I will continue to explore this in the future.

International IT professional migration occurs beyond national lines because of globalization and internationalism, with the goals of information sharing, obtaining higher living standards, as well as for economic reasons. This study aims to explore the factors influencing to the outflow migration of IT professionals in Sri Lanka. This study is the first of its kind in Sri Lanka during the time when the country was dealing with the COVID-19 outbreak and the economic crisis since it rests its originality on information acquired from the local arena. Higher migration rates is a significant concern to Sri Lanka, since second-largest export revenue generating industry is the IT sector. Researchers examined the connections between different factors' effects on migration intention. These studies illustrate some variation in worldwide migration intention factors and trends. They concluded that while the migratory intentions of some countries and identified variables are positively connected, others are negatively connected. Thematic analysis leading to a factor analysis were used in this study to collect data from Sri Lankans. Researchers have conducted interviews for this specific research objective which were followed by a questionnaire using mixed methods. In the results, rotated component analysis, which includes information about the relationships between each variable and the estimated components, is one of the most important outcomes of principle component analysis. As the conclusion, certain policies could encourage innovation, growth, and long-term economic development in Sri Lanka’s IT sector.
