This paper investigated the inflation threshold that ensures financial development fosters industrial growth for a panel consisting of five (5) West African Monetary Zone (WAMZ) countries. The study examined the inflation threshold in the finance-industrial growth relationship from 1990 to 2022. Through the Pooled Mean Group (PMG), panel unit root and cointegration, the study established that a nonlinear inflation threshold exists in the relationship. The PMG result indicate evidence of an inflation threshold estimated as 21.7451% and beyond which the benefits of higher industrial growth as the financial system develops and become efficient turns negative. By policy implication, this support the perception that financial development only works in generating higher rate of industrial growth only when inflation does not exceed or is below 21.7451%. Furthermore, the study also find that trade openness and natural resource rents does foster industrial growth, as exchange rate depreciation and population growth are harmful to industrial output expansion. The study recommends the pursuant of price stability at a level below 21.7451% by adopting an inflation targeting framework.

Talent development in youth football is crucial for clubs, academies, and national associations worldwide. To ensure that talented youths reach their full potential, a comprehensive understanding of the key factors that shape their development is imperative for all stakeholders, including coaches, parents, and sports organizations. This study conducted a systematic literature review (SLR) to identify the key factors influencing talent development in youth football. Methods: After a thorough review process, 27 articles were selected for the final analysis. The SLR examined current research to provide a comprehensive understanding of talent development in youth football. The examination identified seven critical elements that impact talent development: psychological, social, environmental, biological, educational, physical, and mental toughness and resilience. This research highlights the complexity of young football talent development. These results underscore the need for a comprehensive strategy that considers all seven variables. Young athletes, teams, and sports generally stand to gain from these ideas to enhance talent development programs. The potential for enhancing these programs is significant, inspiring a new wave of motivation in the field. Subsequent investigations need to examine the interplay between these variables in various temporal and contextual situations, with a specific emphasis on a comprehensive examination of how sociocultural elements impact talent development pathways.
Desterrando estereotipos en personas con “discapacidad” para su inclusión social y cultural
Authors: Sorgi Marina
Published: November 2024

A lo largo de la historia se han dado distintas concepciones de lo que se entiende por salud, enfermedad y discapacidad. Esto ha producido la construcción de diferentes estereotipos y significaciones imaginarias bajo la idea de “normalidad”, la cual se va delimitando a partir de la ideología dominante en su tiempo y se construye por las luchas de poder, dando lugar a un “nosotros” contraponiéndolo con un “otros”. Dichas construcciones han llevado a que se conciba a la mujer con discapacidad como “anormal”, enferma y portadora de un problema que debe ser tratado a través de un paradigma médico y medicalizante. El objeto del presente trabajo es analizar la triple discriminación sufrida por las mujeres migrantes con discapacidad en Argentina y a través de una reconstrucción histórica, comprender cómo se fue produciendo la redefinición de la otredad en el caso de estas personas.

The ongoing economic crisis in Lebanon has significantly impacted public health, particularly in relation to food safety and foodborne illnesses. This crosssectional study aims to assess the knowledge, attitudes, and practices (KAP) concerning food poisoning among the North Lebanon community during the
crisis. Data were collected from 349 participants aged 18 and above through a structured online questionnaire from March to May 2023. The findings revealed
a decline in food safety awareness since the crisis, with only 26.6% of participants reporting being well-informed, compared to 73.4% prior to the crisis. Social
media emerged as the primary source of food safety information (75.6%), while healthcare workers were underutilized (16.9%). Dairy products (12.6%) and
poultry (11.7%) were identified as the leading causes of food poisoning, particularly from collective catering sources (83.7%). Participants expressed growing
concerns over food quality in restaurants (80.5%) and new food brands entering the market (36.1%). Despite heightened public awareness, gaps in food
hygiene practices persist, underscoring the need for enhanced food safety education and regulatory oversight. These results highlight the urgent necessity
for public health interventions to address food safety risks exacerbated by the ongoing economic challenges in Lebanon.

Published: November 2024

The adoption of digital game-based learning (DGBL) tools in tertiary education is rapidly expanding, driven by digital transformation and the emergence of Education 5.0. This innovative educational paradigm prioritizes personalized learning, collaborative environments, and the integration of advanced technologies to improve educational outcomes. Within this evolving landscape, this research aimed to investigate the relationship between the ARCS motivation model—comprising the components of attention, relevance, confidence, and satisfaction—and the effectiveness of digital game-based learning (DGBL) tools specifically in a Macroeconomics course among tertiary education students. Additionally, the study seeks to identify the most significant determinants among these ARCS components that influence the effectiveness of DGBL tools. Employing a quantitative research design, the study utilizes a structured questionnaire for data collection and applies multiple regression analysis to rigorously examine the relationships among the variables. The findings reveal that high levels of attention, relevance, and confidence are positively and significantly associated with the effectiveness of DGBL tools, while satisfaction was found to be insignificant. Among these, attention emerged as the most impactful factor, highlighting the crucial role of student engagement in maximizing DGBL effectiveness in Macroeconomics courses. This study provides key insights for educators and instructional designers seeking to leverage motivational factors to enhance learning outcomes through digital tools in higher education.
Shadows of Division: Analyzing Direct Action Day and the Complex Path to the Partition of India
Authors: Abrol Vansh
Published: November 2024

The Partition of India in 1947 marks a significant moment in South Asian history, characterized by extensive suffering and displacement. This paper focuses on Direct Action Day, a critical event in August 1946 that sparked violent communal riots in Calcutta, which played a crucial role in driving the subcontinent toward partition. While religious identity is often cited as a primary factor, this analysis argues that the Partition resulted from a complex interplay of multiple factors, including British colonial legacy, socio-economic inequalities, political maneuvering by the Indian National Congress (INC) and the Muslim League, and the constructed nature of religious identities. The influence of British colonial policies, particularly “divide and rule” and separate electorates, fostered communal divisions and political polarization. Additionally, socio-economic disparities and feelings of disenfranchisement among certain Muslim groups intensified tensions, fueling the demand for a separate state. Political leaders, especially Muhammad Ali Jinnah, advocated for Pakistan, reflecting diverse Muslim aspirations, while the INC’s failure to address Muslim concerns contributed to escalating communal unrest. This paper contends that Direct Action Day was not a spontaneous event but rather a culmination of historical legacies, inequalities, and strategic political actions. By examining these dynamics, the paper aims to provide a nuanced understanding of the factors leading to the Partition, illuminating how the intersection of identities and political strategies set the stage for one of history’s most significant transitions, influencing India-Pakistan relations to this day.
Proposal of WIM-LMS Curves for Standardized Curves of Physical Growth in Young Children
Authors: Hayakawa Kentaro , Fujii Katsunori , Tanaka Nozomi
Published: November 2024

The standardized curves of physical development in infancy should reflect the reality of developmental phenomena. Especially curves using percentile values, it is important to verify developmental changes by analyzing growth rate curves. Therefore, a wavelet interpolation model that can derive speed was applied to the 50th percentile and mean values of height and weight as calculated using the LMS method to construct a WIM-LMS curve, while the behavior of infant physical developmental parameters and speed curves were analyzed. The results revealed that both the speed curves were most significantly increased in the first month of life, and FLPV was also detected. Furthermore, mid-growth spurt events were also observed, suggesting that the WIM-LMS curve reflects the reality of infant development and that the WIM-LMS curve can used as a standardized chart of infant physical growth in the future.

Authors: Cho Yoonhee , Choi Boksoo , Kim Hyung Sun
Published: November 2024

Signet ring cell carcinoma (SRCC) is a very rare form of gallbladder (GB) cancer. SRCC is highly invasive and aggressive and mainly exhibits nonspecific symptoms of benign GB lesions; therefore, this cancer is generally diagnosed at an advanced stage. Because it is a rare disease, there are no standard treatment guidelines. Herein, we report a patient with SRCC of GB diagnosed and treated in our hospital. An 80-year-old woman visited the hospital for laparoscopic cholecystectomy for suspected gallstone causing chronic cholecystitis. A routine computed tomography scan revealed a malignancy in the GB and the patient underwent a radical laparoscopic Epidemiology, risk factor, diagnosis and treatment cholecystectomy. On biopsy, she was diagnosed with SRCC of GB with regional lymph node metastasis, which led to postoperative adjuvant 5-fluorouracil chemotherapy. She is currently being followed up without recurrence.

Authors: H Silver Frederick , Deshmukh Tanmay , Nadiminti Hari , Wassef Cindy , Pappert Amy , Lawal Abisola , Patel Aanal
Published: November 2024

Optical coherence tomography is a technique used extensively in ophthalmology to diagnose several ocular diseases. It is being used in dermatology to diagnose skin conditions. We are developing a technique termed vibrational optical coherence tomography (VOCT) to noninvasively image (OCT) and measure the physical properties of tissue components using vibrational analysis in biopsies of skin lesions. In this study we analyze OCT images by subdividing them by pixel intensity differences. OCT images are broken down into green (low pixel intensity), blue (medium pixel intensity), and red (high pixel intensity) images using a fire look-up table. It is demonstrated using this approach that images of normal skin and skin lesions are quite different. The results of this pilot study suggest that this approach may provide information to differentiate benign from cancerous lesions noninvasively. Additional studies are needed to quantitatively analyze these images and to compare the results to the results of vibrational measurements that have been reported previously

التسامح بين أطياف المجتمع العراقي في العصر العثماني 1534-1918
Authors: Dr. Ali Talib Obaid Al-Sultani
Published: November 2024

احتل الأتراك العثمانيون غالب البلاد العربية - من الخليج إلى المحيط - زهاء أربعة قرون من الزمان، ولم يكن العرب قبل هذا الاحتلال بعيدين كل البعد عن الأسلوب التركي في الحكم والسياسة وفي الفكر وضروب الحياة الأخرى.
فقد قامت في العراق مثلآ، وقبل الاحتلال العثماني، دويلات تنتسب من قريب أو بعيد إلى المغول أو التتار، وكلهم في مصطلح التاريخ العربي أقوام من الترك. وقبل قيام هذه الدويلات، سيطرت أقوام تركية على مقدرات الأمور في بغداد وغيرها من المناطق والمدن العراقية المختلفة، وحاولت هذه الاقوام احداث تغيير في التركيبة المجتمعية العراقية خلال المدة الزمنية -عنوان البحث- وهي ١٥٣٤- ١٩١٨. إلا أن مختلف طبقات المجتمع العراقي كانت قد أدت دورها الكبير في المحافظة على الموروث الثقافي من خلال مواجهتها للمؤثرات الخارجية الأجنبية الدخيلة، على الرغم مما في العنصر التركي من حب للتحكم والسيطرة، ومما في طبع حكامها من شدة وقسوة، وقد ورث المجتمع العراقي من العثمانيين الأتراك عاداتهم وسلوكهم من أقوال ورسوم وأفعال، ما زالت تنخر في الموروث العراقي كله، وتعمل فيه هدما وتمزيقا، وهو ما ترك اثارا فكرية ونفسية في المجتمع العراقي بسبب أشكال الحكم العثماني في السياسة والإدارة ونظرته إلى القيم الاجتماعية والمثل الاخلاقية.

The Effects of SMIs’ Source Credibility on Consumers’ Intention to Purchase Local Cosmetic Products Through Attitude Towards Advertisements
Authors: Adel Sitorus Bernadine , Azwa Ambad Sylvia Nabila , Dawayan Cynthia Robert
Published: November 2024

The global influencer marketing industry, valued at USD 21.1 billion in 2023, has gained immense relevance for businesses, with Social Media Influencers (SMI) playing a pivotal role in marketing activities. In the competitive Malaysian local cosmetic industry, leveraging SMIs is particularly promising, given their substantial influence on consumer buying behaviour due to their credibility traits. By extending Ohanian’s (year) seminal 3-dimensional source credibility model, this research employs a 4-dimensional framework tailored to the context of SMIs. Through the purposive sampling technique, this study managed to collect 164 responses via self-administered questionnaires among young adults in the age range of 18–34 years old. Data were analysed using the structural equation modelling-partial least squares (PLS-SEM) method. Findings from this research suggest that SMIs’ trustworthiness and attractiveness affect consumers’ purchase intention through the mediating effects of attitude towards advertisements, while expertise and similarity do not. Essentially, the findings from this study contribute to the existing literature on SMIs’ credibility traits, offering valuable insights for local cosmetic industry stakeholders in their selection for product endorsements.
Interest Divergence: The Root of Losing a Passion for Teaching and Learning.
Authors: Au Nhut Luan , Do Thi Ngoc My , Nguyen Dang Phuoc Hien
Published: November 2024

Purpose: Contemporary education aims to provide society with competent workers. Becoming productive citizens is a common altruistic interest that teachers and learners seek, which theoretically results in teachers' passion for sharing knowledge and learners' desire to become professionals. Surprisingly, teachers progressively fell out of love with teaching, and learners encountered a gradual erosion in their passion for learning. This paper presents the authors’ viewpoint on the origin of this psychological paradox and discusses possible prevention and remedial measures.
Methodology: This narrative review is grounded in available educational literature on passion and interests. 'Interest', 'Passion for teaching', and 'Passion for learning' are primary keywords for searching literature on education. The authors review available papers, present an overall summary and narrate their viewpoint on this psychological paradox.
Findings and discussions: Teaching and learning impact each other. Bilateral contributions are primary requirements for successful training. Exemplary teaching behaviours nourish the desire to learn, and responsible learning attitudes breed a passion for teaching. Policymakers should consider egoistic perspectives and utilitarian thinking as potential psychological characteristics that destabilise the original altruistic interest and can ignite interest divergence. Social factors, including financial burdens/dissatisfaction and heavy workload, ignite and widen interest divergence. Those factors influence teachers and learners in their interests in different ways and cause the split between trainers' and trainees' interests. Progressively and irreversibly, they no longer share the original altruistic goal. As the interest divergence widens, trainers consciously cease prioritising teaching, and learning becomes gradually dispassionate to students. It becomes a vicious circle.
Unique Contribution to Theory, Practice and Policy: Policymakers should develop measures to prevent interest divergence rather than try to escape from the established vicious circle. Due to the complex origin of the divergence, prevention strategies should be holistic and involve multiple stakeholders from different levels. Taking account of egoism and utilitarianism, satisfying financial needs and ensuring curriculum appropriateness are effective prevention measures. Rescuing efforts should be systematic rather than fragmented. Policymakers should consider and respect human weaknesses when dealing with personal characteristics and laying financial burdens down. Minor course corrections are temporary solutions to cease the widening interest divergence.

En la intervención quirúrgica se evidencia adherencias en íleon terminal y ciego, se realiza resección de íleocecal con posterior anastomosis termino-Lateral, enviándose la pieza al servicio de patología que concluye con el diagnostico de: intestino delgado con inflamación crónica y adherencias oclusivas secundarias a endometriosis intestinal. El origen histogénico de la endometriosis ha sido objeto de debate durante años. Actualmente, se aceptan las siguientes tres teorías: de trasplante, metaplásica, y de diseminación vascular o linfática. La literatura, en general, reporta predominio de implantes de endometriosis en la región rectosigmoidea cuando se afecta región intestinal; sólo en algunos casos se menciona involucramiento del intestino delgado.
The Integration Path of Information Technology and Ideological and Political Course from the Perspective of “Four Cause-Theory”
Authors:   College of Teacher Education, Anqing Normal University, LOU Zhi
Published: November 2024

Information technology is a key force of driving the development of modern society, and ideological and political courses are the key courses for implementing the fundamental task of cultivating morality and talent. The integration of information technology and ideological and political courses in universities is not only a necessary measure to adapt to the development of the information age, but also an important way to promote the high-quality development of ideological and political courses in universities. Exploring the integration path of information technology and ideological and political courses in universities from the perspective of Aristotle􀆳s “Four Causes Theory” has important reference significance. To achieve deep integration of information technology and ideological and political education in universities, from the perspective of material factors, adhering to the principle of “content is king” and creating a “golden course” of ideological and political education in universities based on information technology is the foundation and prerequisite; From the perspective of formal factors, adhering to “structural optimization” and innovating the teaching forms of ideological and political courses in universities with information technology elements are important methods; From the perspective of driving factors, adhering to “full staff interaction” and improving the support conditions of information technology are important driving forces; From the perspective of purpose and cause, adhering to the principle of “cultivating virtue and talent” and cultivating young people with both moral integrity and comprehensive development in the new era is the ultimate goal. Promoting the coordinated development of material factors, form. factors, power factors, and purpose factors can provide an effective path for promoting the integration of information technology and ideological and political courses in universities.

Published: November 2024

Purpose

Monocyte chemoattractant protein-1 (MCP-1/CCL2) plays a key role for infiltration of monocytes/macrophages and studies have demonstrated that the MCP-1/C-C chemokine receptor 2 (CCR2) axis might be involved in the pathogenesis and progression of abdominal aortic aneurysms (AAA). Molecular imaging has shown potential for human clinical research studies. We evaluated the expression of CCR2 in patients with small AAA using single-photon emission computed tomography (SPECT) with the technetium-99m-6-hydrazinylnicotinoyl-C-C-chemokine receptor-2 ligand (99mTc-HYNIC-CCR2-L).

Material and methods

A pilot study was performed to evaluate patients with small asymptomatic AAA. The equipment used was a Symbia T2 (Siemens, Germany), with radiolabeled 99mTc-HYNIC-CCR2-L. The SPECT uptake and activity were assessed and counted based on the region of interest (ROI), with nonparametric statistics being employed to compare the aneurysms site, left ventricle (Control 1) and regions with a nondiseased aorta (Control 2).

Results

The three patients were male (100%) (mean age 81 years, and mean AAA maximum diameter of 40 mm, SD 3 mm). All patients tolerated the studies well. Images were obtained at one, two and four hours. The ROI mean value of the aneurysm site was 37,783 (SD 11,890), compared to the left ventricle (Control 1) 16,779 (SD 4397) (p-value = 0.0001); ROI for the nondiseased aortic region (Control 2) was significantly lower, 12,520 (SD 2141) (p-value = 0.0001).

Conclusions

Significant differences of CCR2 expression SPECT were found in the AAA site compared to the left ventricle and nondiseased aortic segments. The introduction of well-designed longitudinal studies with nuclear imaging modalities may assist in the molecular characterization of aneurysmal and rupture prediction.

Entre educação, infâncias e poesia: intervalos para seguir em frente
Authors: Habowski Adilson Cristiano , Ratto Cleber Gibbon
Published: November 2024

A tentativa deste texto, de forma dispersiva, consiste em apresentar o exercício de intervalos realizado em uma tese de doutoramento em educação para pensar as infâncias. Na tese, os intervalos foram pensados como possiblidade de respiração com arte e poesia diante da dureza das análises para pensar de um outro modo as infâncias e ter fôlego para seguir em frente. Os sete intervalos criados ao longo da tese foram reunidos aqui para, no seu conjunto, ‘libertar’ a criança das forças de controle rígido, que buscam criar pretextos para civilizar a criança e suas paixões. Estes intervalos, inspirados em Manoel de Barros, Candido Portinari e Clarice Lispector, permitiram pensar as infâncias e suas brechas na normalização, isto é, de não estabelecer uma verdade absoluta sobre as infâncias e seus tempos, mas sim criar caminhos para pensar sobre como compor outras relações com e no tempo.

Pérdida de carbono orgánico del suelo en sistemas agrícolas de México por cambio climático
Authors: López Teloxa Leticia Citlaly , Monterroso-Rivas Alejandro Ismael
Published: November 2024

El carbono orgánico del suelo (COS) es clave en la salud de los ecosistemas, ya que influye en las propiedades físicas, químicas y microbiológicas del suelo, como la retención de agua, la fertilidad y la diversidad del microbioma. La modelación del COS, mediante aprendizaje automático y teledetección, permite predecir cómo las prácticas agrícolas y el cambio climático afectan su almacenamiento. El objetivo de este estudio fue modelar y proyectar las variaciones en las reservas de COS en suelos agrícolas de temporal y riego en México, bajo condiciones actuales y escenarios futuros de cambio climático. Para ello, se desarrollaron modelos que relacionan el COS con variables como el índice de Lang (precipitación y temperatura), altitud, pendiente, densidad aparente, clase textural y profundidad del suelo. Los modelos capturaron las características del relieve del terreno y su relación con el tipo de agricultura y los contenidos de COS en los suelos. Los mayores contenidos de COS se encontraron bajo agricultura de riego. Sin embargo, ante el cambio climático, se prevén disminuciones en el COS de hasta 7 %, así como incrementos de temperatura de hasta 6 °C y aumentos de precipitación del 12 %. La disminución del COS podría agravar las emisiones de gases de efecto invernadero y reducir la capacidad del suelo para almacenar carbono. El estudio destaca la importancia de implementar prácticas de manejo sostenible y fomentar investigaciones multidisciplinarias que permitan mitigar los efectos adversos. Además, demuestra que es posible simular el comportamiento del COS y generar modelos útiles para evaluar escenarios y apoyar la toma de decisiones.

Published: November 2024

Abstract. Simulation of the carbon cycle in climate models is important due to its impact on climate change, but many weaknesses in its reproduction were found in previous models. Improvements in the representation of the land carbon cycle in Earth system models (ESMs) participating in the Coupled Model Intercomparison Project Phase 6 (CMIP6) include the interactive treatment of both the carbon and nitrogen cycles, improved photosynthesis, and soil hydrology. To assess the impact of these model developments on aspects of the global carbon cycle, the Earth System Model Evaluation Tool (ESMValTool) is expanded to compare CO2-concentration- and CO2-emission-driven historical simulations from CMIP5 and CMIP6 to observational data sets. A particular focus is on the differences in models with and without an interactive terrestrial nitrogen cycle. Overestimations of photosynthesis (gross primary productivity (GPP)) in CMIP5 were largely resolved in CMIP6 for participating models with an interactive nitrogen cycle but remaining for models without one. This points to the importance of including nutrient limitation. Simulating the leaf area index (LAI) remains challenging, with a large model spread in both CMIP5 and CMIP6. In ESMs, the global mean land carbon uptake (net biome productivity (NBP)) is well reproduced in the CMIP5 and CMIP6 multi-model means. However, this is the result of an underestimation of NBP in the Northern Hemisphere, which is compensated by an overestimation in the Southern Hemisphere and the tropics. Carbon stocks remain a large uncertainty in the models. While vegetation carbon content is slightly better represented in CMIP6, the inter-model range of soil carbon content remains the same between CMIP5 and CMIP6. Overall, a slight improvement in the simulation of land carbon cycle parameters is found in CMIP6 compared to CMIP5, but with many biases remaining, further improvements of models in particular for LAI and NBP is required. Models from modeling groups participating in both CMIP phases generally perform similarly or better in their CMIP6 compared to their CMIP5 models. This improvement is not as significant in the multi-model means due to more new models in CMIP6, especially those using older versions of the Community Land Model (CLM). Emission-driven simulations perform just as well as the concentration-driven models, despite the added process realism. Due to this, we recommend that ESMs in future Coupled Model Intercomparison Project (CMIP) phases perform emission-driven simulations as the standard so that climate–carbon cycle feedbacks are fully active. The inclusion of the nitrogen limitation led to a large improvement in photosynthesis compared to models not including this process, suggesting the need to view the nitrogen cycle as a necessary part of all future carbon cycle models. Possible benefits when including further limiting nutrients such as phosphorus should also be considered.

Abstract. Airborne measurements are pivotal for providing detailed, spatiotemporally resolved information about atmospheric parameters and aerosol and cloud properties, thereby enhancing our understanding of dynamic atmospheric processes. For 30 years, the US Department of Energy (DOE) Office of Science supported an instrumented Gulfstream 1 (G-1) aircraft for atmospheric field campaigns. Data from the final decade of G-1 operations were archived by the Atmospheric Radiation Measurement (ARM) Data Center and made publicly available at no cost to all registered users. To ensure a consistent data format and to improve the accessibility of the ARM airborne data, an integrated dataset was recently developed covering the final 6 years of G-1 operations (2013 to 2018, https://doi.org/10.5439/1999133; Mei and Gaustad, 2024). The integrated dataset includes data collected from 236 flights (766.4 h), which covered the Arctic, the US Southern Great Plains (SGP), the US West Coast, the eastern North Atlantic (ENA), the Amazon Basin in Brazil, and the Sierras de Córdoba range in Argentina. These comprehensive data streams provide much-needed insight into spatiotemporal variability in the thermodynamic quantities and aerosol and cloud properties for addressing essential science questions in Earth system process studies. This paper describes the DOE ARM merged G-1 datasets, including information on the acquisition, data collection challenges and future potentials, and quality control processes. It further illustrates the usage of this merged dataset to evaluate the Energy Exascale Earth System Model (E3SM) with the Earth System Model Aerosol–Cloud Diagnostics (ESMAC Diags) package.
Catchment hydrological response and transport are affected differently by precipitation intensity and antecedent wetness

Published: November 2024

Abstract. Hydrological response and transport are distinct catchment behaviours that have both been intensively studied, but rarely together. The hydrologic response characterises how quickly, and how strongly, streamflow reacts to precipitation inputs, whereas transport characterises how quickly precipitation reaches the stream. Here we use sub-daily time series of hydrometeorological fluxes and stable water isotopes to quantify both hydrological response and transport in two intensively studied temperate catchments. Consistent with previous studies, we find that hydrologic response is much quicker than transport. However, we also find that catchment wetness and precipitation intensity influence hydrologic response and transport in different ways. Increased antecedent wetness results in stronger runoff responses, primarily mobilising more old water, while increased precipitation intensity results in a faster propagation of the runoff response signal, and the delivery of greater proportions of recent precipitation to streamflow. Considered together, response times and travel times provide insights into runoff generation mechanisms, flow paths, and water sources.
The impact of future changes in climate variables and groundwater abstraction on basin-scale groundwater availability

Abstract. Groundwater is under pressure from a changing climate and increasing anthropogenic demands. In this study, we project the effect of these two processes onto future groundwater status. Climate projections of Representative Concentration Pathway 4.5 (RCP4.5) and Representative Concentration Pathway 8.5 (RCP8.5) from the Coupled Model Intercomparison Project Phase 6 (CMIP6) drive a one-way coupled fully distributed hydrological and groundwater model. In addition, three plausible groundwater abstraction scenarios with diverging predictions from increasing, constant, and decreasing volumes and spatial distributions are used. Groundwater status projections are assessed for short-term (2030), mid-term (2050), and long-term (2100) periods. We use the Bandung groundwater basin as our case study; it is located 120 km from the current capital city of Indonesia, Jakarta, which is currently scheduled for relocation. It is selected as the future anthropogenic uncertainties in the basin, related to the projected groundwater abstraction, are in agreement with our developed scenarios. Results show that changes in the projected climate input, including intensifying rainfall and rising temperature, do not propagate notable changes in groundwater recharge. At the current unsustainable groundwater abstraction rate, the confined piezometric heads are projected to drop by maxima of 7.14, 15.25, and 29.51 m in 2030, 2050, and 2100, respectively. When groundwater abstraction expands in proportion to present population growth, the impact is worsened almost 2-fold. In contrast, if groundwater abstraction decreases because of the relocated capital city, groundwater storage starts to show replenishment potential. As a whole, projected groundwater status changes are dominated by anthropogenic activity and less so by changes in climatic forcing. The results of this study are expected to show and inform responsible parties in operational water management about the issue of the impact of projected climate forcing and anthropogenic activity on future groundwater status.
Numerical Solution of Differential Equations Using the Wavelet-Based Galerkin Method with Fibonacci Wavelets
Authors: Angadi L. M.
Published: November 2024

Differential equations form the foundation of scientific theories that address numerous real-world physical challenges. Numerical methods enable the resolution of complex problems through relatively simple operations. A significant advantage of numerical methods, compared to analytical methods, is their ease of implementation on modern computers, allowing for quicker solutions. Galerkin's method belongs to a broader category of numerical techniques. Additionally, wavelet analysis represents a promising domain within applied and computational research. This paper establishes a wavelet-based Galerkin method for numerically solving differential equations, utilizing Fibonacci wavelets as trial functions. The proposed method yields results comparable to existing techniques and provides solutions that closely approximate exact answers for certain problems, thereby demonstrating its effectiveness and accuracy.
Medizinische Selbstbestimmung in Alten- und Pflegeheimen
Authors: Niedrist Verena-Maria
Published: November 2024

Das vorliegende Werk beleuchtet das Recht auf Selbstbestimmung im Zusammenhang mit medizinischen Behandlungen in den Institutionen der Alten- und Pflegeheime. Feststellungen der präventiven Menschenrechtskontrolle zufolge sind alte Menschen oftmals gefährdet, einer Fremdbestimmung und damit einhergehenden Einschränkungen bezüglich ihres Selbstbestimmungsrechts zu unterliegen. Diese Gefahr besteht in Alten- und Pflegeheimen in besonderem Maße, denn institutionellen Betreuungseinrichtungen ist in der Regel eine Machtdisparität immanent. Vor diesem Hintergrund wird der Rechtsrahmen bei der Betreuung in Alten- und Pflegeheimen aus öffentlich-rechtlicher, zivilrechtlicher und strafrechtlicher Sicht dargelegt. Im Speziellen werden die Anforderungen an die informierte Einwilligung bei medizinischen Behandlungen und damit die Rechtmäßigkeit derartiger Interventionen erörtert. Ein besonderes Augenmerk liegt auch auf den Vertretungsmodellen, die mit Inkrafttreten des 2. ErwSchG im Jahr 2018 umfassend reformiert wurden. Diese sind für in ihrer Entscheidungsfähigkeit eingeschränkte Personen von Relevanz. Dargestellt werden sowohl die Modelle der Erwachsenenvertretung als auch die Möglichkeiten der Vorausplanung von Behandlungen – beispielsweise in Form einer Patientenverfügung. Neben der Auswertung einschlägiger Literatur, Gesetzesmaterialien und Judikatur kommt es zur umfassenden Analyse der relevanten einfachgesetzlichen Normen anhand der grundrechtlichen Gewährleistungen, wobei insbesondere das aus Art 8 EMRK ableitbare Selbstbestimmungsrecht im Fokus der Überprüfung steht.
La memoria culturale dei Romani
Authors: Bettini Maurizio
Published: November 2024

Questo saggio affronta il problema della memoria culturale dei Romani, relativamente ai primi secoli della loro storia. Lo studio è condotto nella prospettiva delle ricerche inaugurate da Maurice Halbwachs e Jan Asmmann e pone le basi teoriche della ricerca a partire da un importante passo del De republica di Cicerone. Nella seconda parte passa in rassegna i principali ‘strumenti di memoria’ che hanno facilitato la trasmissione della memoria culturale a Roma: come la permanenza dei mores, i riti, i luoghi, i racconti e così via attraverso i quali la più antica memoria culturale romana ha potuto consolidarsi ed essere trasmessa.
