Considerable brain and neural alterations associated with obesity affect behavior, thought, and emotional control. Changes in brain shape and function are revealed by neuroimaging research, especially in reward-processing regions like the striatum and prefrontal cortex. These alterations could result in a rise in the desire for foods rich in calories and a decline in judgment. Furthermore, neuroinflammation and changes in neurotransmitter systems are linked to obesity and can impact mood and cognitive function. To effectively treat obesity and the health problems it causes, it is essential to comprehend these brain alterations. Obesity is a complex medical problem that has significant effects on brain structure and function in addition to physical health. With an emphasis on changes in brain regions related to reward, food management, and cognitive function, this study examines the most recent research on the neuronal modifications linked to overweight and obesity.

The national and global reality is complex; the problems linked to economic development and social are marked by constant crises and profound changes (globalization, demography, technological revolution, persistent social hiatuses that impact the governance of nations) that modify the structure of society, and the relationships established between its members transforming their customs and consequently their values. The accentuated pluralism, the weakness of beliefs, ethical emotivism, moral relativism and immanentism in our culture are predominant factors that explain the permanent crisis of values in which we live. Shared values are key to success, the main initiatives of any organization how permanence and its growth can crumble when there is a lack of cultural alignment and strategic in relation to the transcendent Good and human goods. In this sense, the lack of unity in the direction, management and educational actions in an organic manner has as its causes the diversity of cognitive representations of those who collaborate in an institution that is the product of environments, experiences and education received in a global context of postmodernity that perverts moral behavior (MacIntyre A.1987), generating different motivations that stimulate their behavior, as well as the diversity of needs and goals that move them. On the other hand, the lack of unity in goals has the consequences of persistence in the collaborators of diverse assessments about the institutional mission and vision, thereby favoring the prevalence of diverse interests, the dispersion of efforts and the variation of results. The shortage or loss of objective references to identify the goods that favor human growth has strengthened an emotivist culture in society.

Published: February 2025

This study examines the impact and challenges of implementing mentoring programs in Hifz al-Quran teaching at tahfiz institutions in Malaysia. Mentoring has been proven to be an effective approach not only in assisting students to memorize the Quran but also in shaping their character, morality, and personal excellence. Using a qualitative approach through document and content analysis, this study explores how the role of teachers as mentors influences the academic, personal, and motivational aspects of tahfiz students. The findings reveal that structured mentoring programs, supported by traditional teaching methods such as talaqqi and musyafahah, can enhance students’ motivation, self-confidence, and memorization skills. However, this study also identifies several challenges in implementing mentoring programs in the digital era, including limited technological skills among teachers, gaps in access to technology, and difficulties in maintaining effective mentor-mentee relationships online. The study recommends the development of suitable digital learning modules and the provision of technological training for tahfiz teachers. Additionally, family support and the creation of a conducive learning environment are recognized as critical factors for the success of these programs. With continuous efforts and the prudent use of technology, it is hoped that mentoring programs will continue to have a positive impact on Hifz al-Quran teaching, thereby strengthening tahfiz education in Malaysia comprehensively.

Published: February 2025

Os sinistros de trânsito constituem um problema de saúde pública no Brasil, e para implementar ações eficazes na mitigação desse fenômeno, é imprescindível o uso de técnicas analíticas que permitam entender os fatores que contribuem para essa questão. Dessa forma, objetivo desse estudo é analisar a infraestrutura dos locais críticos para motociclistas, em um trecho da BR-153, entre os Km 501 e Km 505, com o apoio do software ViDA do iRap. Como resultado, foram encontradas características da infraestrutura que contribuem a ocorrência dos sinistros, como objetos próximos à via, barreiras de contenção inadequadas, acostamentos estreitos, ausência de sonorizadores e alta velocidade dos veículos. Por consequência, como medidas mitigadoras, foram propostas a adequação das barreiras de contenção, remoção de objetos perigosos, instalação de sonorizadores e controle da velocidade. O estudo permitiu constatar fragilidades que aumentam o risco de sinistros para motociclistas nos trechos analisados e comprometem a segurança também de outros usuários da via. Recomenda-se para estudos futuros a inclusão de contagem de tráfego e dados sobre pedestres e ciclistas para uma avaliação mais abrangente da segurança viária.
EcoPro-LSTM𝑣0: A Memory-based Machine Learning Approach to Predicting Ecosystem Dynamics across Time Scales in Mediterranean Environments
Authors: Cattry Mitra , Zhao Wenli , Nathaniel Juan , Qiu Jinghao , Zhang Yao , Gentine Pierre
Published: February 2025

Abstract. Climate change is anticipated to alter the global water and carbon cycles, but the spatiotemporal effects of these climate-induced shifts remain poorly understood. Of particular relevance are the variations in rainfall intensity and frequency affecting the carbon and water cycles from daily to interannual time scales. Yet, the current models fail to reproduce these processes as capturing the complex interactions and interrelated dependencies at different timescales (daily to seasonal) requires the simultaneous estimation of multiple interconnected ecological processes. To address this challenge, here, we introduce initial version of our ecosystem process modelling using Long Short-Term Memory approach (EcoPro-LSTM𝑣0) which uses a temporal multitask deep learning model designed to predict ecosystem responses, focusing on critical terrestrial variables, including ecosystem respiration (RECO), gross primary productivity (GPP), evapotranspiration (ET), and surface soil water content (SWC). Our approach leverages the capabilities of LSTM networks to capture the interdependencies of those processes across time scales. LSTMs excel at time-series prediction because they can learn long-term relationships and patterns in data. We trained and tested our model using long-term data from FLUXNET2015 Mediterranean sites (at hourly and daily time-steps), mainly in the USA and Europe, known for their ecological diversity and significance. We demonstrate our model's outperforming against state-of-the-art data products and test the robustness of our model and findings through k-fold cross-validation. We also showcase the model's interpretability in revealing how short- and long-term atmospheric drivers, like precipitation, influence GPP in Mediterranean climates. This model and accompanying insights can help better understand and manage ecosystems under climate change, especially in response to changing extreme events.
Scale invariance in kilometer-scale sea ice deformation

Published: February 2025

Abstract. Large-scale modeling of sea ice dynamics assumes scale-invariance that is used to calibrate and validate current models. Validity of this assumption, particularly its lower spatial limit, remains poorly understood. Identifying when, where, and why scale-invariance does not apply is essential for linking meter-scale sea ice mechanics with large-scale sea ice dynamics and climate models. Here we address this challenge by employing unique high-resolution ship radar imagery from MOSAiC expedition in an analysis based on novel deep learning-based optical flow technique. Together these allow capturing sea ice kinematics consistently at unprecedented 20-meter spatial and 10-minute temporal resolutions over an entire winter season and into summer over a 10-kilometer spatial domain. We show that the sea ice within this domain remains largely quiescent for extended periods, with distinct events revealing a 102-meter lower limit for scale-invariance that endures as the ice cover undergoes seasonal evolution. This threshold remains stable throughout the winter, even as deformation features become more localized and distinct, suggesting an intrinsic mechanical constraint that is invariant under varying external conditions. Once the ice transitions to a floe-dominated configuration in summer, no comparable scaling signature emerges. Our results give a limit under which continuum models fail to capture critical fine-scale processes, highlighting the need for approaches accounting for detailed description of discontinuous spatial and temporal behavior of sea ice.
A fresh look at the pre-industrial air-sea carbon flux using the alkalinity budget
Authors: Planchat Alban , Bopp Laurent , Kwiatkowski Lester
Published: February 2025

Abstract. The disparities in estimates of the ocean carbon sink, whether derived from observations or models, raise questions about our ability to accurately assess its magnitude and trend over recent decades. A potential factor contributing to this inconsistency is the pre-industrial air-sea carbon flux, which is thought to arise globally from an imbalance between riverine discharge and sediment burial of carbon. The characterization of this flux is essential for isolating the anthropogenic component of the total air-sea carbon flux estimated from observations; however, it remains highly uncertain, limiting confidence in the impactful applications of the Global Carbon Budget (GCB). In this study, we propose a fresh look at the pre-industrial air-sea carbon flux using the alkalinity budget. We demonstrate the relevance of a novel theoretical framework that directly enables the calculation of the riverine/burial-driven pre-industrial carbon outgassing using both carbon and alkalinity budgets. We also introduce a practical framework to evaluate the spatial distribution of this flux through a series of ocean biogeochemical simulations. Our reassessment, grounded in existing carbon and alkalinity budgets, yields an estimated riverine/burial-driven pre-industrial carbon outgassing of 0.49 [0.34; 0.70] PgC yr-1, which is lower than the most recent central estimate of 0.65 ± 0.30 PgC yr-1. This adjustment partially reduces the disparities between observation-based and model-derived estimates of the anthropogenic ocean carbon sink. Using a composite simulation derived from a linear combination of our sensitivity experiments, we reassess the spatial distribution of this flux, attributing 29 % to the southern region (south of 20° S), 40 % to the inter-tropical region (20° S–20° N), and 31 % to the northern region (north of 20° N). Notably, these findings represent an intermediate distribution compared to those used in the GCB over time, with recent values at 14 %, 64 %, and 22 %, and historical values at 49 %, 25 %, and 26 %. Addressing the current inconsistencies between the combined carbon and alkalinity budgets is thus an urgent priority for building confidence in the global riverine/burial-driven pre-industrial carbon outgassing, and intermodel comparisons are required to constrain its regional distribution.

Authors: Kingston Daniel G. , Cooper Liam , Lavers David A. , Hannah David M.
Published: February 2025

Abstract. With mountainous topography and exposure to midlatitude westerly storms causing frequent atmospheric river landfall and associated hydrohazards, medium-range forecasting of extreme precipitation is imperative for New Zealand. Here, the European Centre for Medium-Range Weather Forecasts Extreme Forecast Index (EFI) is applied to two variables in forecast week 2: total precipitation (TP–EFI) and vertically integrated water vapour transport (IVT–EFI). Results reveal the TP–EFI sometimes outperforms the IVT–EFI in capturing extreme precipitation events – in contrast to past Europe-based research. Importantly, these case studies highlight the need to develop further understanding of sources of predictability for extreme precipitation in different geographical contexts.

Authors: Vélez-Coto María , Morejón-Llamas Noemí , Cárdenas-Rica María Luisa
Published: February 2025

Los prejuicios y las actitudes xenófobas son esquemas cognitivos que dan forma a las emociones y el comportamiento. Estos emergen con mayor profusión en el ecosistema mediático digital y se articulan como discursos de odio, especialmente a través de la emisión de comentarios en redes sociales, atraídos por la presencia de fotografías. Así, el objetivo general de este estudio es explorar la respuesta emocional que tienen los adultos ante las imágenes de personas racializadas y no racializadas para relacionarla con la probabilidad de emitir mensajes negativos en espacios como las redes sociales. En definitiva, se pretende comprender qué provocan estas imágenes en la audiencia digital y qué emoción les impulsa a convertirse en propagadores del odio. Para ello, se reclutaron 103 participantes españoles (X edad = 40,32), a través de Mechanical Turk (MTurk), a quienes se les mostraron 46 imágenes, junto con las escalas pictográficas de evaluación de la respuesta emocional (Self-Assessment Manikin [SAM]). Asimismo, se preguntó la probabilidad de escribir un comentario y su carácter positivo o negativo. Los resultados mostraron diferencias significativas entre las categorías fotográficas en la respuesta emocional y en la probabilidad de publicar un comentario negativo, siendo las imágenes de personas racializadas las que se asociaron a un mayor riesgo. El patrón emocional de quienes indicaron una alta probabilidad de emitir un comentario negativo se identificó como miedo en las imágenes negativas de personas racializadas y como odio en las imágenes positivas. Estos resultados contribuyen a la caracterización emocional de los emisores del discurso del odio en los medios digitales y redes sociales, específicamente aquellos que se relacionan con actitudes xenófobas.

Authors: Trujillo Patricio , Vallejos Alexandra
Published: February 2025

This study explores the perceptions and experiences of women in Ecuador regarding humanized childbirth and obstetric violence. This article systematizes a case study conducted in the Organization of Anteña Women (OMA) in the canton of Antonio Ante, in the province of Imbabura, through qualitative ethnographic research. In-depth interviews were conducted with women who experienced different childbirth experiences. As a result, various levels of knowledge about humanized childbirth were identified. Some women understood the cultural and autonomy aspects well, while others were unaware of the concept, which can negatively impact their childbirth experience. It was observed that mothers access information through formal sources, such as courses and talks in health centers. Additionally, the presence of a companion during childbirth was considered an essential component of humanized childbirth. Most interviewees positively valued effective communication and respectful treatment by healthcare personnel. However, aspects for improvement were detected, such as the need for training healthcare personnel to ensure respect for mothers' decisions, clear communication, and continuous emotional support. The results reveal that, although there are advances in the implementation of humanized childbirth, practices of obstetric violence persist, negatively affecting women's experiences.

Published: February 2025

The research investigates the MHD Casson hybrid nanofluid in the presence of thermal radiation, nanolayers, and mixed convection inside a porous, permeable rotating cone. A slip boundary condition was applied for the problem. The governing flow model describing the problem captures Darcy-Forchheimer, mixed convection, thermal radiation, and dissipation. The coupled PDEs representing flow are obtained and transformed to ODEs via similar variables. The obtained ODEs are solved numerically by the shooting method together with the order six Runge Kutta method. MAPLE mathematical software is used to code and simulate the problem. The effects of embedded flow parameters (tangential and azimuthal velocities, thermal field, Nusselt number, and skin friction coefficient) are presented graphically and in tabular form and discussed in details. The results reveal that higher interfacial nanolayer parameters increase the thermal field. The magnitude of heat transfer rate boosts via greater fluid material and thermal radiation values, while it diminishes through the Prandtl number and Eckert number.

This article explores how people work as e-commerce entrepreneurs under the control of platforms and the blueprint of rural development laid out by China’s central government. It asks: through what mechanisms do the state and the platform govern rural e-commerce entrepreneurs to achieve their economic and political goals? And how the unprecedented scale of e-commerce in rural China has reshaped local communities and people’s lives? It argues that the popularization of e-commerce in rural China is encouraged by the partnership of state and Chinese platform giants as a public-private alliance. Rural e-commerce entrepreneurs are aspiring to be their own bosses, nonetheless, they are in “the digital cage” where work and life get blurred in the social domain. The family-based online entrepreneurship in rural China contributes to China’s future developmental mode from the grassroots.

Authors: Marito Winanda
Published: February 2025

This research aims to describe gamification-based learning using Kahoot to enhance students' interest in online learning. This study employs a quantitative approach with a quasi-experimental method. The design used is one group pretest-posttest. The sample in this study consists of 30 students from the Physical Education, Health, and Recreation study program. Data collection techniques were conducted through a learning interest questionnaire given before the learning (pretest) and after the learning (posttest) and an observation sheet for the implementation of learning. Data analysis used paired t-test. The research results indicate that there is a 15.5% increase in student learning interest with a t-value of 15.847, p < 0.001, which means there is a significant difference in the increase of student learning interest before and after the implementation of gamification-based learning with Kahoot. The success rate of the learning implementation is 88.75% across all observed aspects, including lesson preparation, execution, student activities, and time management. These findings indicate that gamification-based learning using Kahoot can enhance student learning interest in online learning.

Published: February 2025

This study aims to determine the implementation of the independent learning curriculum in the context of students' mathematics learning outcomes. The type of research used is quantitative with an ex-post facto design. The sample determination technique was carried out by random sampling. Primary data collection is in the form of midterm exam results in mathematics subjects as well as population and research samples, namely class III B students with a total of 33 students. The data was analyzed in a quantitative descriptive manner. The results of the study show that the implementation of the independent learning curriculum is no longer based on themes but subjects that are effective by each teacher based on an agreement on what field of study to be taught, the application of the independent curriculum has begun to be well adopted by students. Based on the results of data analysis, there was a significant difference in the results of the mid-semester exam in the ganji semester (the implementation of the 2013 curriculum) and the results of the mid-semester exam in the even semester (the implementation of the independent learning curriculum) after the paired sample t-test was applied which showed a significant difference in the comparison of mathematics learning outcomes of grade III B students at SD Karya Bakti I Medan.
Navigating the Remote Workplace: The Role of Leadership and Its Implications for Employee Work Outcomes
Authors:   , Shi Jian
Published: February 2025

Rapid advancements in digital technology combined with the recent COVID-19 pandemic have shifted remote work arrangements from a discretionary, flexible alternative into a widespread and sometimes even mandatory model of working. These changes require leaders to fulfill some new roles that effectively address the important and unique needs and demands of employees in increasingly remote workplaces. Such demands, in particular, involve maintaining and improving employee engagement, assuring employee health and safety, as well as fostering a sense of connectedness within the team. Accordingly, the present dissertation aims to address a crucial fundamental research question: What are the specific leadership behaviors that effectively influence employees in modern remote workplaces, and how do they work? I tackled this overarching question by identifying four specific aspects of crucial leadership behaviors and examining each of them in a separate empirical chapter. In Chapter 2, I investigated whether and how leaders through their communication influenced remotely working employees to stay engaged with their work. I then examined, in Chapter 3, if and how health-oriented leadership buffered employees’ safety and health risks in workplaces during the pandemic. In Chapter 4, I studied whether and how identity leadership addressed employees’ loss of connectedness in a remote working setting. Finally, in Chapter 5, I examined if and how identity leadership helped to overcome employees’ negative psychological and behavioral outcomes in a hybrid working setting. Across these chapters, I demonstrated that leaders who engage in remote communication with employees and identity leadership behaviors are effective in maintaining engagement and fostering social connectedness among remotely working employees. However, I found no evidence supporting the significant roles of health-oriented leadership in alleviating employees’ safety and health risks. Taken together, this dissertation provides novel theoretical and practical insights into the newly crucial roles of leadership in increasingly remote working contexts and sheds light on their implications for employee work outcomes.
