Analysis of Hydrological Natural Disasters in the Belém Metropolitan Region: Impacts, Progression and Dimensions of Vulnerability
Authors: Paes Gleicy Karen Abdon Alves , Pontes Altem Nascimento
Published: February 2025

Objective: This study aims to analyze the occurrences of floods and inundations in the Metropolitan Region of Belém (MRB), correlating data and indicators from the period between 2010 and 2021 to risk mapping of hydrological processes, focusing on impacts, progression, and dimensions of vulnerability.
 
Theoretical Framework: The research is based on the occurrence of floods and inundations in the MRB. The Amazon region presents climatic characteristics that contribute to environmental alterations.
 
Method: : Indicators from the Automatic Recovery System (SIDRA) of the Brazilian Institute of Geography and Statistics (IBGE) were collected and correlated with data from the risk area mapping conducted by the Geological Survey of Brazil (CPRM). The impacts, progression, and dimensions of vulnerability were analyzed.
Results and Discussion: A population increase was observed, while investments decreased. The analysis confirmed that population growth in flood-prone areas exacerbates risks. The Pareto diagram showed that 80% of the consequences stem from the economic, social, and environmental dimensions. The Severity, Urgency, and Tendency (SUT) matrix identified priority dimensions.
 
Research Implications: Despite efforts to improve services, public policies, along with the lack of adequate planning, make the MRB vulnerable to new occurrences due to the multiple facets of vulnerability that affect the population.
 
Originality/Value: This study investigates the occurrences of floods and inundations in the MRB, addressing the impacts, progression, and dimensions of vulnerability.

Authors: Melnykova-Kurhanova Olena , Ryzhko Olena
Published: February 2025

The study analyzes the survival experiences of students during the information blockade imposed during the siege of Mariupol, Ukraine, in 2022. Using the case study method, posts, photos, and videos from open sources were examined to fill in gaps regarding students who remained under siege. Additionally, semi-structured anonymous interviews were conducted with students who shared their experiences of survival, including three who provided comments on their time under occupation and their departure from the city. They described the conditions they faced during shelling, the information blockade, and exposure to Russian information aggression and propaganda. Without electricity or mobile communication, students accessed news via medium and long radio waves, conserved phone battery power, and sought mobile internet from higher floors of high-rise buildings to download website headlines or Telegram messages.
Russia’s policy in the Eurasian area amid confrontation with the West
Authors: Zhiltsov S. S.
Published: February 2025

Western sanctions against Moscow have led to a radical change in the Russian foreign policy course. The Western direction of Russia’s diplomacy, which had been promoted since the late 1980s, began to change at the end of the XX and at the beginning of the XXI centuries. Amid the Western pressure, Moscow began to give higher priority to the eastern direction, expanding political and economic contacts with non-Western states. Russia’s main attention was turned to the countries of the Eurasian area, for which the policy of the West also created significant risks. As a result, over the past decades, Moscow’s diplomacy has made a radical turnaround, establishing a new framework of economic relations and creating a solid foundation for the further development of political ties with the Eurasian states. Furthermore, in recent years, the forming of new ties with Eurasian countries has rapidly accelerated, primarily due to the worsening of the relations between Russia and the West. This factor provoked a fundamental revision of Moscow’s foreign policy, which was forced to respond to the confrontational course of the Western states. The article analyzes the main results that Russia has achieved in its relations with the Eurasian countries. The research concludes that the shift of Russian policy towards the Eurasian area has a long-term basis and meets the interests of Moscow.
Ukrainian crisis: origins, consequences and prospects
Authors: Neimark M. A.
Published: February 2025

The internationalization of the Ukrainian crisis and the “Ukrainization” of the international agenda have exposed the deep goals and strategic aspirations of the West, led by the United States, in modern geopolitics. The American strategic claim to organize the world order at its own discretion and the excessive conviction in its overestimated ability to be an unchanging world hegemon are causing a systemic failure. Its flip side is a sharp increase – through the prism of the events in Ukraine – in confrontational rhetoric and political, sanctions-economic and military-strategic activity against Russia, which have reached peak values. The Ukrainian crisis has become not only a bifurcation milestone in the development of world political processes, but also a new milestone in understanding and rethinking transformational shifts, divisions and isolations in global politics. Today, their unusually sharp critical assessments and conclusions are no longer isolated in the Western-centric discourse, which, we emphasize, have a tendency to increase in quantity and have a more clearly expressed qualitative content than before. Thus increasing the degree of predictive and evaluative accuracy of specialized analytical reflection, which initially assumes taking into account underestimated or, conversely, overestimated factors, circumstances and event flows in world politics.
The Laughing Buddha: The Education of Compassionate Leaders through Improvisational Play
Authors: Chiu Belinda
Published: February 2025

With an urgency to build a generative future, educational systems do not have a choice but to pay attention to how and what we train our future leaders. Yet there is still a gap as leadership studies are often relegated as a “soft” skill, rather than integrated as technical knowledge critical to the holistic effectiveness of a tertiary education. As a result, there is often a disconnect between students immersed in the idealistic bubble of the academy and graduates navigating life outside. Inquiry- and reflective-based methods of contemplative practices may be critical for leaders to avoid short-term, short-sighted decisions that ill prepare people and communities for continuous change and upheaval. With human, more than human, and planetary health at risk, the need for wise leadership is necessary to discern the paths forward for a more generative future. Fortunately, there has been increased attention of and call for leadership rooted in compassion as a strategic approach to leadership. Research around contemplative practices, such as gratitude and mindful meditation, offer evidence that they help strengthen the capacity to lead with and for compassion. This article explores another, often overlooked, contemplative practice: improvisational play and humor. Indeed, compassion and humor have been inextricably linked across many knowledge traditions. This article examines how the applied contemplative practice of improvisational play and humor offer an untapped opportunity for institutions of higher education to close the gap between theory and practice and to fulfill its responsibility of cultivating wise leaders of tomorrow.

Halka Arz İşlemleri ile Yatırımcı Portföyleri Arasındaki İlişkinin İncelenmesi
Authors: Balıkçı Bilen , Tunçel Mert Baran
Published: February 2025

Şirketlerin sürdürülebilirliğini sağlama ve yüksek finansal giderlerinin mali tablolar ile kazançlar üzerinde oluşturduğu olumsuz etkileri minimize etme amacı, şirketleri halka arz yoluyla kaynak sağlamaya yönlendirmektedir. Bu çalışmada, Haziran 2012-Şubat 2024 dönemine ait aylık veriler kullanılarak halka arz endeksi (XHARZ) ile yerli ve yabancı yatırımcıların portföy değerleri arasındaki ilişki incelenmiştir. Fourier nedensellik testi sonuçlarına göre, halka arz endeksi ile yatırımcı portföy değerleri arasında herhangi bir nedensellik ilişkisi tespit edilememiştir. Bu bulgular, yatırımcı portföylerinin yalnızca halka açık şirket hisselerini içermemesi, portföylerin tahvil, emtia ve gayrimenkul gibi farklı varlık sınıflarını da kapsayabilmesi ile açıklanabilir. Ayrıca, Türkiye’de finansal okuryazarlık oranının düşüklüğü, halka arz yatırımlarının kısa vadeli kazanç aracı olarak değerlendirilmesi ve geleneksel yatırım araçları olan altın ve dövize yeniden yönelim gibi faktörlerin de bu sonuçların ortaya çıkmasında rol oynadığı düşünülmektedir. Bu unsurlar, analiz sonuçlarının özgün yapısına ve yatırımcı davranışlarının dinamiklerine ilişkin önemli bilgiler sunmaktadır. Çalışmanın sonuçları, finansal okuryazarlık seviyesinin artırılması ve halka arz süreçlerine ilişkin stratejik düzenlemelerin gerekliliğini de ortaya koymaktadır.
A Comparison of Premier-presidential and President-parliamentary Systems Based on Presidential Elections
Authors: Metin Abdullah , Uğurlu Ömer Faruk
Published: February 2025

While forms of government are generally divided into four main categories, Shugart and Carey suggested that the semi-presidential system should be divided into two categories: president-parliamentary and premier-presidential. This study aims to assess the validity of their suggestion by comparing these two systems based on presidential elections. We hypothesize that president-parliamentary and premier-presidential systems significantly differ from each other in terms of the effective number of parties (ENP), the vote ratio of the first party to the second party (VR1:2), and the round in which the presidential elections conclude. To test this hypothesis, we created a dataset by calculating ENP and VR1:2 for the last five presidential elections in 58 countries that adopted either a premier-presidential or president-parliamentary system. The Laakso-Taagepera Index (L-T Index) was used for ENP calculations. The dataset was analyzed using SPSS. The results confirm the hypothesis: ENP is lower in president-parliamentary systems (2.28) and higher in premier-presidential systems (3.22). VR1:2 is higher in president-parliamentary systems (7.02) and lower in premier-presidential systems (3.23). Along with this quantitative evidence and considering the differences in democratic functioning between the two systems, it becomes evident that these two systems are not subtypes of the semi-presidential system, but distinct systems in their own right.

Published: February 2025

Статья, посвященная анализу композиции «From me flows what you call Time» («Из меня струится то, что вы называете Временем») японского композитора Тору Такэмицу, акцентирует уникальность подхода к объединению восточных и западных музыкальных традиций. Рассмотрены источники и числовая символика композиции, состав оркестра, особенности группы ударных инструментов. Впервые представлен анализ используемых Такэмицу типов акустического материала (тема Времени, вертикальные агрегаты, сонорно-геометрические фигуры), результатом чего является многослойность звучания пьесы. В работе использованы элементы музыкальной герменевтики (проблема интерпретации и понимания композиции) и феноменологии (структурно-музыкальные аспекты анализа). В выводах подчеркивается свойственная творчеству Такэмицу установка на живой диалог между различными традициями. Глубина философско-эстетических идей композитора преодолевает культурные барьеры и создает новое эстетическое пространство. Рассмотрены определенная числовой символикой координация различных музыкальных и внемузыкальных уровней композиции и объединенность тринадцать разделов композиции «From me flows what you call Yime» разнообразием акустического звучания.

The article analyzes the composition «From me flows what you call Time» by Japanese composer Toru Takemitsu and emphasizes the uniqueness of the approach to combining Eastern and Western musical traditions. The sources and numerical symbolism of the composition, the composition of the orchestra, and the features of the percussion group are considered. For the first time, an analysis of the types of acoustic material used by Takemitsu (the theme of Time, vertical aggregates, sonorous-geometric figures) is presented, which results in the multi-layered sound of the piece. The work uses elements of musical hermeneutics (the problem of interpretation and understanding of the composition) and phenomenology (structural and musical aspects of the analysis). The conclusions emphasize the focus on a lively dialogue between different traditions, characteristic of Takemitsu's work. The depth of the composer's philosophical and aesthetic ideas overcomes cultural barriers and creates a new aesthetic space. The coordination of various musical and extra-musical levels of the composition, determined by numerical symbolism, and the unification of the thirteen sections of the composition "From me flows what you call Time" by the diversity of acoustic sound are considered.

Published: February 2025

Crystal structure classification of binary intermetallic structures with 1:3 stoichiometry was done with simple machine learning algorithms. The successful crystal structure segregation is attributed to the novel set of descriptors comprising both compositional and structural features. The dataset includes 97 features, and a total of 2366 reported compounds adopting six different structure types. The unsupervised learning method based on principal component analysis (PCA) followed by clustering using the K-means method was applied to cluster compounds belonging to different structure types. Using the recommendation engine, we predicted the expansion of the clusters and then identified cluster/structure-type overlap. PuNi3-type was among the clearly segregated structure types according to the unsupervised model, and a novel representative, TbIr3, was selected for experimental validation, adopting this structure. The final supervised machine learning predictions were done with PLS-DA, SVM, and XGBoost confidently predicting the novel TbIr3 to belong to the PuNi3-type with an accuracy of 96.6%, 99.8%, and 99.9% respectively. Analysis of the features reveals that the main contributing features to the AB3 crystal structure segregation are the average shortest distance count of A element, the total number of sites of B atom, and the total number of second shortest distance count of B atom. Given that the predicted PuNi3-type of the TbIr3 phase could be controversial due to the extensive study of the Tb–Ir phase diagram and the reports of the TbIr3 in two different structure types, we conducted two independent experimental structural validations to confirm the existence of the TbIr3 in PuNi3-type structure. Subsequent theoretical validation explains that Ir-Ir contacts are the primary stability factor of TbIr3 in PuNi3-type structure over other structure types.

Published: February 2025

Heterogeneous catalysts are crucial in modern societies as they promote sustainability by enabling lower-energy pathways for various chemical reactions. While Density Functional Theory (DFT) computations can provide critical insights into how heterogeneous catalysts operate at the atomic level, they are limited by computational costs and unfavorable scaling with system size. Recently, machine learning interatomic potentials (MLIPs) have emerged as a promising alternative to DFT, offering near-DFT accuracy at significantly reduced cost. In this perspective, we discuss the application of MLIPs in heterogeneous catalyst modeling as a surrogate for DFT. We detail how MLIPs have been applied in thermal catalysis to probe active sites, enable studying complex metallic and nanoporous catalysts, and investigate the reconstruction of catalytic surfaces. We review the use of MLIPs in electrocatalysis and photocatalysis, emphasizing their capabilities in studying transition metal oxide surfaces and solid-liquid interfaces. We also discuss the current limitations of MLIPs, particularly their challenges with transferability and description of non-local interactions. Finally, we conclude by identifying promising and underexplored domains in which MLIPs can further advance our understanding of heterogeneous catalysts.

Telegram Application to Monitor and Control of Automatic Railway Crossing Prototype Using Automatic Transfer Switch
Authors: Wusandi Janu Ramadhan  , Amirullah Amirullah , Asepta Surya Wardhana
Published: February 2025

A railroad crossing is a device that functions to close and open roads that limit or stop public traffic lanes so that vehicles stop temporarily and give priority to trains. Failure of a railroad crossing will have fatal consequences because it will cause accidents and cause fatalities, injuries, or other material losses. The accident occurred because there was no equipment or failure of officers when operating the railroad crossing. To overcome these obstacles, the railroad crossing was made automatically. This paper proposes a prototype control of an automatic railroad crossing using an automatic transfer switch (ATS) monitored by the Telegram application. The main power source of the railroad crossing prototype is a photovoltaic generator system consisting of solar modules, inverters, and batteries. ATS is proposed so that the system is able to automatically transfer the power supply from the solar power generator to PLN electricity if the battery voltage is not enough to drive the railroad crossing or vice versa. The results of the study show that the combination of a 50 Wp solar module and a VRLA battery (12V and 12Ah) is able to store and generate electricity to drive the railroad crossing. The INA219 sensor is able to measure the current, voltage, and power of the PV module and battery. Arduino Uno is able to process voltage and current sensor data, send and receive UART data (RX TX), and communicate with ESP8266. Data from ESP8266 can then be sent and monitored remotely by the Telegram application via Arduino-Uno. The results of DC current and DC voltage tests using the INA219 sensor between the Telegram application and Multimeter are able to produce errors below 5%. The Telegram application is also able to monitor the DC voltage and DC current of PV modules and batteries, as well as the DC adapter voltage and DC adapter current from PLN remotely, and the status of opening and closing the railway crossing gate based on the power supply selection by ATS.

Published: February 2025

The rapid development of digital technology and the widespread adoption of the internet have significantly transformed media consumption patterns, especially among young audiences in Indonesia. This study aims to explore the preferences and motivations of Indonesian youth (ages 15-30) in selecting digital platforms over traditional media, applying the Theory of Planned Behavior (TPB) as a framework. TPB posits that Attitude Toward Behavior, Subjective Norms, and Perceived Behavioral Control are key factors influencing behavioral intentions. Utilizing a quantitative, survey-based approach, the research examines the extent to which these factors impact young viewers' media preferences. Results reveal that Subjective Norms and Perceived Behavioral Control strongly influence digital media engagement, while Attitude Toward Behavior is less impactful. These findings highlight the importance of social influences and usability in shaping media preferences among young Indonesians. The insights gained could guide media providers in developing strategies that resonate with this demographic, adapting content and platform features to better meet the needs of an evolving digital audience

On the internal structures of hydraulic structures of a number of HPPs, water manifestations are noted, that is, the appearance of traces of moisture outside the culvert, which can lead to a change in the operational condition of the structure or damage to expensive equipment. At the same time, the processes that cause such manifestations are extremely diverse. The formation of filtration foci can be due to a gradual change in the condition of block joints; degradation of cement stone due to corrosion or under the influence of loads exceeding the design ones; increase in filtration costs, as well as the features of the construction of structures. As an example of structures that are characterized by water manifestation, it is necessary to cite the Rybinsk and Uglich hydroelectric power plants, for which during the entire period of operation there is a water manifestation near the turbine shafts of hydroelectric units and on the surfaces of the barrels of spiral chambers. In 2019-2021, in order to establish the causes of these phenomena, specialists of the branch of JSC Institute Hydroproject-NIIES conducted a survey of the concrete structures of the Uglich and Rybinsk hydroelectric power plants, during which it was found that the main causes of water in the areas under consideration for each station are largely similar, but not identical.
360-degree projection simulation versus traditional simulation in undergraduate paramedicine education: a pilot randomised controlled trial
Authors: Vella Rachael , Simpson Paul , Thyer Liz
Published: February 2025

Introduction: Simulation is considered a mainstay for teaching and assessment in various clinical fields, including paramedicine. Simulation fidelity in educational practice is constantly changing to accommodate the integration of extended realities (XRs), such as augmented,
mixed and virtual realities. However, little research has been undertaken to directly compare these newer, technology-enhanced methods, such as 360-degree projection simulation, with the traditional methods used in undergraduate education. The purpose of this research was to provide a direct
comparison, exploring their effect on ratings of self-perceived performance in second-year paramedicine students.Methods: Using a single-site, parallel randomised controlled, non-blinded trial, participants were randomly allocated to a three-day intensive 360-degree projection (intervention)
or traditional (control) simulation programme. Ratings of self-perceived performance were collected using the Seattle University Simulation Evaluation tool at three different time points: after participants’ first simulation as ‘lead paramedic’ on Day 1 of the intensive programme
(Rating 1), after their final simulation on Day 3 of the intensive programme (Rating 2) and after their final simulation in a follow-up programme after a nine-week washout period (Rating 3).Results: Out of the 37 participants randomly allocated, 20 fulfilled the study requirements,
with 11 in the 360-degree projection group and nine in the traditional simulation group. Participants consistently reported higher ratings of self-perceived performance in the traditional simulation group, in comparison to the 360-degree projection simulation group (p = 0.04). While no difference
was seen between groups after the intensive programme (Rating 2), a notable difference was observed between groups at Rating 3 in favour of the traditional simulation group (p = 0.02).Conclusion: This pilot study suggested that measures of self-perceived performance were lower when
using 360-degree projection simulation spaces. While there may be some benefit to this form of simulation as an adjunct to current traditional methods used, further research, including studies that are appropriately powered and include objective outcome measures, is needed to understand the
measure of effectiveness in a practical setting and to inform future educational interventions.
Foreign-language skills of student paramedics studying undergraduate Paramedic Science in the UK: a nationwide cross-sectional exploratory study
Authors: Finney Owen
Published: February 2025

Introduction: Communication is essential in healthcare, but language barriers between patients and clinicians can hinder care quality, especially as the UK sees an increasing number of non-native English speakers. The 2021 UK census revealed that 5.1 million people do not speak
English as a first language, with many having limited or no proficiency. Despite these trends, little research has been carried out to explore the experiences of these individuals in pre-hospital care, where language challenges often arise. UK paramedic education includes communication training,
but foreign-language learning is not part of most curricula. Some universities offer optional language modules, yet there is no data on how many paramedics or student paramedics speak additional languages. Clinicians with foreign-language skills could enhance patient satisfaction and reduce
communication barriers, but there is a lack of pre-hospital evidence in this area. This exploratory study aimed to capture the foreign-language skills of student paramedics in the UK, addressing a gap in the literature and laying the groundwork for future research.Methods: This
exploratory study employed a quantitative, cross-sectional design using an online survey distributed to student paramedics across 24 higher education institutions in the UK during April and May 2024. The survey captured demographic data and language competencies, with descriptive statistics
used for analysis.Results: Out of 105 respondents, 73 were female (69.5%), and the mean age was 23.65 (± 8.25). Over half (53.3%) reported proficiency in at least one foreign language, predominantly languages spoken in Europe, such as French (48.2%), Spanish (35.7%) and German
(21.4%). Most respondents had beginner-level skills (64.3%), with no formal language training in their programmes. However, 57.7% expressed interest in studying an optional foreign-language module.Conclusion: This study found that over half of student paramedics possess foreign-language
proficiency. The majority of the sample indicated a desire to study a foreign language if given the opportunity during their paramedic training. Given the increasing linguistic diversity in the UK, integrating language modules into paramedic education could enhance patient care and satisfaction.
Further research is needed to explore the feasibility of such training and its impact on pre-hospital care outcomes for non-native English speakers.

Desde su descubrimiento, la incorporación de iones de tierras raras en ferritas tipo espinela ha demostrado ser significativa debido a su capacidad para ajustar y mejorar diversas propiedades como ópticas, eléctricas y magnéticas, lo que les permite ser aplicadas en tecnología, electrónica y biomedicina. Específicamente, el método de síntesis sol-gel asistido por autocombustión ha facilitado la preparación eficaz de nanocompositos de ferritas con una composición precisa y homogénea, asegurando una alta pureza de fase. Este estudio se enfoca en sintetizar y caracterizar nanocompositos de ferritas (CoEu0.1Fe1.9O4)X/(Zn0.5Mn0.5Sm0.1Fe1.9O4)1-X utilizando dicho método, con variaciones de composición dentro del rango(0<x<1.0). La caracterizaciónincluyó análisis por difracción de rayos X (DRX), que confirmó la cristalinidad y estructura de espinela de las muestras. La morfología se evaluó mediante microscopía electrónica de barrido de emisión de campo (FE-SEM), revelando una estructura esférica con un tamaño promedio de partículas de 18 nm, aunque se observaron conglomerados en ciertas áreas. El análisis elementala través de EDXS confirmó la presencia de todos los elementos, mientras que el espectro FT-IR mostró bandas características de vibraciones metal-oxígeno. Por último, el análisis de absorción UV-Vis indicó un rango de energía de banda prohibida de 1.31 a 1.48 eV para diferentes valores de (0<x<1.0), sugiriendo propiedades semiconductoras en las muestras.
