Actores y discursos en las políticas educativas de la Universidad Nacional de Agricultura de Honduras
Authors: Murillo Lizardo Orlando David
Published: January 2025

Este artículo describe los actores y discursos involucrados en las políticas educativas de la Universidad Nacional de Agricultura (UNAG) de Honduras en el proceso de intervención de la Comisión nombrada por el Congreso Nacional durante los años 2017-2020. El enfoque de investigación fue el cualitativo, se utilizó como método el estudio de casos, de tipo exploratorio, desde las miradas del ciclo de políticas y el modelo de formación inductiva de categorías de análisis. Los datos se recolectaron entre los años 2021 y 2022 mediante las técnicas de análisis de documentos y la entrevista semiestructurada y se examinaron a través de la técnica análisis cualitativo de contenido, esta última con el apoyo del Sofware ATLAS.ti, versión 8. Los resultados identifican múltiples actores y discursos que influyeron en las políticas educativas de la UNAG, tanto en la dimensión internacional —Organización de las Naciones Unidas para la Educación, la Ciencia y la Cultura -UNESCO-, Banco Mundial, Unión Europea, Consejo Superior Universitario Centroamericano (CSUCA), Conferencias Mundiales y Regionales de la Educación Superior— como nacional —Gobierno Central, Congreso Nacional, partidos políticos, Universidad Nacional Autónoma de Honduras (UNAH)—. Además, la Comisión Interventora promovió una reforma institucional que provocó conflictos internos, especialmente entre grupos de docentes por el control del gobierno universitario y el establecimiento de una nueva normativa interna. Se concluye que las políticas educativas de la UNAG, bajo la dirección de la Comisión Interventora, estuvieron influenciadas por agendas tanto internacionales como nacionales que reflejaron dinámicas de poder y conflictos internos. Si bien estas medidas contribuyeron a mejorar algunas estructuras administrativas y académicas, también exacerbaron las divisiones políticas y generacionales principalmente entre el personal docente.

Authors: Aravena Domich Marcela , Ramos Contreras Cristobal
Published: January 2025

Este ensayo se realizó bajo la modalidad de revisión documental de investigación y artículos que aportan elementos teóricos, datos y fundamentos legales acerca del fenómeno de la extraedad escolar como situación de inclusión educativa en las escuelas de Colombia y algunos países de la región. Tuvo como objetivo, comprender la realidad educativa que subyace en la condición de extraedad escolar, como proceso de inclusión educativa. Se entiende por extraedad a la situación donde los estudiantes tienen un rango de edad mayor al promedio de otros estudiantes en el mismo grado. Este problema es originado por causas diversas: sociales, familiares y académicas, y tiene un índice de afectación en el desarrollo personal, profesional y familiar de los sujetos educativos. Es por ello, que desde los entes gubernamentales y organizaciones sociales se han planteado políticas y planes de acción con para minimizar las repercusiones negativas en el desarrollo individual y social. A manera de conclusión, la extraedad escolar genera situaciones de exclusión y segregación escolar, así mismo, las políticas de atención implementadas han venido logrando mejorar los índices de acceso y cobertura de los estudiantes pero, aún falta por trabajar en estrategias para la permanencia y atención pedagógica pertinente; porque los docentes y directivos docentes no tienen la suficiente formación profesional y personal para gestionar e implementar un currículo flexible y pertinente que coadyuve por un adecuado a las necesidades de inclusión de estos estudiantes.
English Voices and Echoes
Authors:   University of Rzeszow, Weretiuk Oksana
Published: January 2025

The aim of the book is to reach students, researchers, and the wider community of readers. However, its main purpose is to present the diverse voices of literatures written in English and point at similar features between them and those more distant from them – linguistically, culturally and geographically – Ukrainian and Polish literatures. I metaphorically called the latter “echoes”- as a close parallel to the ideas, feeling, or events. A cultural terrain covering a large part of Europe and North America is offered, unfortunately too often disturbed by the dangerous channels of political history. The book contains 16 essays addressing how writing in English constructs the narratives of ethnic identity, home and belonging, earth-man relations, human-animal bonds, dramatic historical events. Moreover, a comparison with selected Slavic literatures highlights these specific national accents in the discussed works by English, Irish, Canadian and American writers. This approach proves helpful for studying literature across linguistic and cultural boundaries. The First Chapter introduces the issues concentrated on English literature itself, and it is opened with an article written 15 years ago, about Andrzej Tretiak, the outstanding Polish professor of the interwar period, expert in English literature, comparatist, who was the first in Poland to define the characteristic, definitive features of English literature. Chapter Two discusses the concepts of Irish literature, mostly in comparison with Ukrainian literature and in reference to the dramatic historical events of both nations, including some Polish accents. In Chapter Three the literary concepts of the formation of multicultural Canadian identity and Canadian literature in English are discussed as well as the phenomenon of Canadian prairie poetry (Andy Suknaski) and native Cree artist (Allan Sapp). Chapter Four deals with some issues of comparative studies in reference to literatures in English. Therefore, my research has an international character and focuses on critical understanding of how literatures differ from one another (even those written in the same English language) and what those differences mean. The book includes some articles published a long time ago, and many of them were written for the current edition. They will summarize my almost twenty-year work as a comparative scholar at the English Department of the University of Rzeszów.
Influence of mineral filler on the thermal conductivity of polymer composites
Authors: Melnyk Liubov
Published: January 2025

The study focuses on the development of polymer composites based on the Latex 2012 aqueous dispersion with mineral fillers of volcanic (andesite) and technogenic (fly ash from Burshtyn TPP and Kurakhove TPP) origin, aimed at achieving optimal thermal insulation properties. The main problem addressed was determining the influence of the type, concentration, and combination of fillers on the thermal conductivity of composites. High thermal conductivity of polymeric materials significantly limits their application in thermal insulation systems, making it crucial to investigate the mechanisms of interfacial interactions between fillers and the matrix for creating effective compositions.
The sizes of filler crystallites were determined using the Scherrer method: for andesite – 110 nm, fly ash B – 100.4 nm, and fly ash K – 113 nm. These data indicate the fillers' ability to affect phonon scattering in the material, reducing overall thermal conductivity. The thermal conductivity of the fillers is as follows: fly ash B – 0.2072 W/m·K, fly ash K – 0.2241 W/m·K, and andesite – 0.2118 W/m·K. Fly ash B demonstrated the best results due to its low thermal conductivity and high surface energy, which contributes to better interaction with the polymer matrix.
An analysis of the dependence of composite thermal conductivity on temperature and filler concentration showed that increasing filler concentration increases thermal conductivity due to the formation of thermal bridges between particles. However, combining different fillers in optimal proportions can mitigate this effect. Based on the Nielsen model, the composite compositions were optimized to achieve minimum thermal conductivity. The best results were obtained for a binary filler system of fly ash B and andesite in a 53:35 mass ratio, providing the lowest effective thermal conductivity of the composite – 0.173 W/m·K. Other successful combinations include fly ash B with fly ash K (60:40 wt. %) and andesite with fly ash K (45:55 wt. %), which also demonstrate significant improvements in thermal insulation properties.
The proposed compositions can be applied in the field of energy-efficient construction, thermal regulation systems, thermal insulation materials for industrial equipment, and other areas requiring low thermal conductivity. The research results are also valuable for developing materials that operate under significant temperature variations (from –125 °C to +100 °C), providing stable thermal insulation properties.
TÉDIO E VIOLÊNCIA: UMA LEITURA A PARTIR DE O ESTRANGEIRO DE ALBERT CAMUS.
Authors: Domingues Thiago , De Franco Clarissa , De Paula Blanches
Published: January 2025

O presente artigo tem como objetivo estabelecer a relação do fenômeno do tédio e da violência enquanto uma das tessituras que compõem o modo de subjetivação contemporânea. Nosso ponto de partida e fio condutor para esta análise é o livro O estrangeiro (1957), do escritor franco-argelino Albert Camus. Nosso enfoque metodológico consiste na análise interdiscursiva da primeira parte do livro colocando em perspectiva a cadeia de significados ocultos nas profundezas de uma vida aparentemente superficial, como é o caso de Meursault, a partir de uma narrativa de literatura. Conclui-se que a violência emerge como resposta autômata ao tédio, à quebra dos vínculos amorosos com a realidade intersubjetiva sendo o personagem principal da obra símbolo dessa violência que emerge e da urgência para que novos modos de subjetivação e estar no mundo sejam incorporados à ética do existir.
Dynamic Foraging in Swarm Robotics: A Hybrid Approach with Modular Design and Deep Reinforcement Learning Intelligence
Authors: Hammoud Ali , Iskandar Alaa , Kovács Béla
Published: January 2025

This paper proposes a hybrid approach that combines intelligent algorithms and modular design to solve a foraging problem within the context of swarm robotics. Deep reinforcement learning (RL) and particle swarm optimization (PSO) are deployed in the proposed modular architecture. They are utilized to search for many resources that vary in size and exhibit a dynamic nature with unpredictable movements. Additionally, they transport the collected resources to the nest. The swarm comprises 8 E-Puck mobile robots, each equipped with light sensors. The proposed system is built on a 3D environment using the Webots simulator. Through a modular approach, we address complex foraging challenges characterized by a non-static environment and objectives. This architecture enhances manageability, reduces computational demands, and facilitates debugging processes. Our simulations reveal that the RL-based model outperforms PSO in terms of task completion time, efficiency in collecting resources, and adaptability to dynamic environments, including moving targets. Notably, robots equipped with RL demonstrate enhanced individual learning and decision-making abilities, enabling a level of autonomy that fosters collective swarm intelligence. In PSO, the individual behavior of the robots is more heavily influenced by the collective knowledge of the swarm. The findings highlight the effectiveness of a modular design and deep RL for advancing autonomous robotic systems in complex and unpredictable environments.
Speaker-Specific Method of Spoofing Attack Detection Based on Anomaly Detection
Authors: Evsyukov Mikhail
Published: January 2025

Most research in the field of voice presentation attack detection relies on the speaker-independent approach. Nevertheless, several scientific works indicate that using the speaker-specific approach, which involves utilizing prior knowledge about the identity of the claimed speaker to enhance the accuracy of spoofing detection, is likely to be beneficial. Therefore, the goal of this work is to propose a speaker-specific method of spoofing attack detection based on anomaly detection and to evaluate its applicability to the detection of synthesized speech and converted voice. Artificial neural networks pre-trained for the tasks of spoofing detection, speaker recognition, and audio pattern recognition are used for feature extraction. A set of anomaly detection models are used as backend classifiers. Each of them is trained on bonafide data of a target speaker. The experimental evaluation of the proposed method on the ASVspoof 2019 LA dataset shows that the best speaker-specific spoofing detection system, which uses an anomaly detection model and a neural network pre-trained for the task of speaker recognition, achieves an EER of 4.74%. This result suggests that embeddings extracted by networks pre-trained for speaker recognition contain information that can be utilized for spoofing detection. In addition, the proposed method allowed to increase the accuracy of three baseline systems pre-trained for the task of spoofing detection. Experiments with two baseline systems on the ASVspoof 2019 LA dataset showed relative improvement in terms of EER by 7.1% and 9.2%, and in terms of min t-DCF by 4.6%. Experiments with the third baseline system on the ASVspoof 2021 LA dataset showed relative improvement in terms of EER by 3.9% without significant improvement of min t-DCF.
Analytical Review of Task Allocation Methods for Human and AI Model Collaboration
Authors: Ponomarev Andrew , Agafonov Anton
Published: January 2025

In many practical scenarios, decision-making by an AI model alone is undesirable or even impossible, and the use of an AI model is only part of a complex decision-making process that includes a human expert. Nevertheless, this fact is often overlooked when creating and training AI models – the model is trained to make decisions independently, which is not always optimal. The paper presents a review of methods that allow taking into account the joint work of AI and a human expert in the process of designing (in particular, training) AI systems, which more accurately corresponds to the practical application of the model, allows to increase the accuracy of decisions made by the system “human – AI model”, as well as to explicitly control other important parameters of the system (e.g., human workload). The review includes an analysis of the current literature on a given topic in the following main areas: 1) scenarios of interaction between a human and an AI model and formal problem statements for improving the efficiency of the “human – AI model” system; 2) methods for ensuring the efficient operation of the “human – AI model” system; 3) ways to assess the quality of human-model AI collaboration. Conclusions are drawn regarding the advantages, disadvantages, and conditions of applicability of the methods, as well as the main problems of existing approaches are identified. The review can be useful for a wide range of researchers and specialists involved in the application of AI for decision support.

Hermann Parzinger: Die unbewegte Bewegerin. Über die Erfindung der Achse
Authors: Parzinger Hermann
Published: January 2025

Unter all den Erfindungen, die der Mensch im Laufe seiner Geschichte erdacht hat, gehört die Achse zweifellos zu den bedeutendsten. Achsensymmetrisches Denken muss bereits dem Frühmenschen vertraut gewesen sein. Anders scheint es kaum vorstellbar, dass er schon vor Hunderttausenden von Jahren in der Lage war, perfekt gearbeitete und symmetrisch gestaltete Faustkeile herzustellen. Rein technisch betrachtet ist eine Achse recht einfach zu beschreiben. Sie bildet ein Element von länglicher Form und meist rundem Querschnitt. Das Rad ist dabei funktional untrennbar mit der Achse verbunden. Durch die Verknüpfung von Achse und Rad entstehen die ersten automotorischen Maschinen der Menschheit. Dazu gehören Wagen, durch tierische oder menschliche Kraft gezogen, die Töpferscheibe, von Hand bewegt, oder Wasserräder, durch die Fließkraft des Wassers betrieben. Wagen und Töpferscheibe sind dabei deutlich älter als Wasserräder.
Jutta Allmendinger, Jan Wetzel: Die Achsen der Gesellschaft
Authors: Allmendinger Jutta , Wetzel Jan
Published: January 2025

Achsen sind den Sozialwissenschaften in vielerlei Form geläufig. Sie sind Denkmittel, wenn man Beobachtungen entlang rein gedachter Linien ordnet, den Begriff der Achse also wie eine Metapher nutzt. Und sie dienen als Arbeitsmittel, wenn man die Unendlichkeit empirischen Rauschens mit sauberen statistischen Methoden sondiert und klassifiziert. Die großen Linien, entlang welcher man die Ordnung der Gesellschaft denkt, die Metaphern, werden also in viele Fragen und Hypothesen kleingearbeitet und dann je einzeln auf ihren Realitätsgehalt hin empirisch geprüft: Gesellschaftswissenschaft als Statistik. Metaphern können ohne Statistik nicht überprüft werden. Die Statistik allein bringt uns aber auch nicht weiter. Das sozialwissenschaftliche Arbeiten ist ein kuratorisches Arbeiten, in dem man auf Grundlage vieler Daten theoriegeleitet die wesentlichen Achsen erkennt, auswählt und interpretiert.

Tensiones en torno al despliegue policial de proximidad en barrios populares de Buenos Aires (2020-2021)
Authors: Zajac Joaquín , Gamallo Leandro
Published: January 2025

Introducción: algunos barrios populares de la Ciudad de Buenos Aires tienen desde hace unos años un policiamiento específico que incluye, entre otras cosas, el despliegue de fuerzas federales de carácter militar. Objetivo: este artículo examina el papel de las Unidades de Prevención Barrial de la Gendarmería Nacional Argentina en dos barrios populares de la Ciudad de Buenos Aires durante las restricciones de movilidad impuestas entre mayo de 2020 y junio de 2021 para mitigar la propagación del COVID-19. Metodología: a través de una metodología cuantitativa basada en el análisis estadístico de registros de incidencias policiales, buscamos describir el impacto de los despliegues policiales de proximidad en contextos de alta vulnerabilidad social y dar cuenta de las transformaciones en las prácticas policiales impuestas a raíz de la emergencia sanitaria. Conclusiones: el estudio muestra, en relación con la pandemia, una sobrecarga de trabajo de los efectivos vinculada a tareas de control poblacional y sanitaria. Por otro lado, se describen un conjunto de prácticas vinculadas a la resolución de conflictos y atención de demandas y problemáticas sociales que desbordan el accionar vinculado a la represión de delitos penales y el control social de poblaciones subalternas, un trabajo que fue especialmente visibilizado durante la pandemia.
Heroïnes de rondalla i narradores orals, possibles paral·lelismes. El cas de Tàrbena (Marina Baixa)
Authors: Monjo i Mascaró Joan-Lluís
Published: January 2025

L’especialització dels estudis etnopoètics en un àmbit restringit, com pot ser una comunitat humana petita, permet l’assoliment d’uns objectius d’anàlisi més aprofundits. És aquest el cas del treball que s’ha dut a terme, que se centra en el patrimoni rondallístic d’una localitat valenciana (Tàrbena). Focalitzant l’estudi en la figura de la dona s’enriqueix la visió global del fenomen. Es constata el paper preponderant de la dona com a agent de transmissió de la rondalla, en general, i de la rondalla meravellosa, en particular. Es posa en evidència el predomini de la dona entre els narradors amb una major competència comunicativa i una major implicació emocional. Així, es posa de manifest l’existència d’un fons rondallístic en què la dona és la protagonista i encarna valors positius. Com que aquesta tipologia de rondalles sol ser més característica dels repertoris femenins, es comprova que les narradores populars són transmissores de valors progressistes a través de les rondalles. Alhora, contribueixen, també, a reforçar els valors patriarcals, ja que també són agents difusors de rondalles en què es condemnen les dones que s’aparten de les normes marcades per la societat.

Instagram and #Wellness: Uncovering Gender and Body Patterns
Authors: Flores Ana Marta M. , Sepúlveda Rita
Published: January 2025

The concept of “wellness” and its associated representations have become key aspects of modern culture, with social media platforms like Instagram playing a significant role. Not only do these platforms serve as spaces for the public expression of wellness-related topics, but they also influence public perceptions. This becomes particularly meaningful when these expressions are linked to gender. Our research explores how wellness and gender are depicted in popular Instagram posts. By analysing 300 public Instagram posts tagged with #wellness from 2023, we investigate whether traditional notions of gender and bodies are challenged or reinforced. Wellness is a multifaceted process, but our findings show that users often adhere to a narrow concept. To understand these representations, we focused on posts tagged with #wellness, particularly those in the physical category. The study employed a digital methods approach (Rogers, 2013) and thematic analysis (Braun & Clarke, 2006, 2021), uncovering three primary themes: Practices & Workout, Body & Expressions, and Clothing & Adornment. Predominantly, all themes in the context of wellness depict gender in a binary form and bodies as thin or athletic. These traditional gender and body norms are perpetuated on Instagram, reinforcing societal standards of beauty and body image. Instagram’s engagement logic preferentially promotes content conforming to dominant societal norms, strengthening these patterns. Alternative or counter-narratives, while they exist, often face challenges in gaining visibility due to both algorithmic biases and cultural predispositions. Although Instagram has the potential to offer a platform for such counter-narratives, our findings indicate that normative content continues to dominate in terms of visibility and engagement.

Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, TOKARUK Lyudmyla , DANILEVSKA Oleksandra ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: January 2025

Background. Military operations on the territory of Ukraine for specialists of the State Emergency Service (hereinafter – SES) have led to specific features of the process of preventing professional burnout. Social and pedagogical work on the prevention of professional burnout of SES specialists is very relevant and important, as rescuers are entrusted with increased responsibility for the fate of victims, they constantly face psychological stress, emotional mood swings due to unforeseen situations that arise in the course of their professional activities.
The relevance of the research topic is to determine the directions of socio-pedagogical work to prevent professional burnout of specialists of the state emergency services in the context of military operations on the territory of Ukraine. A systematic approach to the organisation of sociopedagogical work to prevent professional burnout of specialists of the state emergency service helps individuals to work as a team in a coordinated manner to solve social and psychological problems. The level of success and safety of SESU specialists in extreme conditions can be significantly increased through properly organised socio-psychological and socio-pedagogical support.
Methods. At the stage of protracted military operations in Ukraine, methods of social and pedagogical work to prevent professional burnout of SESU employees are emerging and developing, which enable social educators and psychologists of the service to more effectively anticipate unplanned emotional overload of specialists of various SESU units. One of the basic methods of social and pedagogical work to prevent professional burnout of specialists of the state emergency services in Ukraine in the conditions of war is the method of gradual self-improvement of each specialist, the curriculum for the development of resilience skills, which can be mastered through advanced training courses, trainings, conferences, exchange of experience with colleagues.
Results. We analysed the causes and diagrammed the consequences of professional burnout of SES specialists, developed methodological recommendations for social educators on the stages of preventing professional burnout of specialists of the State Emergency Services.

Сonclusions. In this way, specialists of state emergency services are able to withstand the daily psychological pressure that not only delays their professional development, but also prevents them from being fully motivated and engaged in constructive work in groups, organisations or in relationships with colleagues, and hence the consequence of professional burnout.
Synthetic Data Revolutionizes Rare Disease Research: How Large Language Models and Generative AI are Overcoming Data Scarcity and Privacy Challenges
Authors: Goyal Mahesh Kumar
Published: January 2025

The scarcity of patient data has been a bottleneck for finding solutions in healthcare, and in the challenging field of rare diseases, this bottleneck is worsening due to the increasing use of data analytics. With medical research anchored problems—limited availability of data and stringent privacy regulations preventing data sharing—synthetic data is becoming a developing solution. Using advanced generative AI models, synthetic data can accurately represent the statistical properties of real-world patient data, while preserving the privacy of patients. Gan and VAEs are among other powerful aids to develop synthetic high quality dataset for a rare disease. By balancing between privacy and utility, these models helped generate data to support research and analytics without compromising patient confidentiality and without reducing analytical performance. Further protection against data breaches and re?identification risks with generated AI can be accomplished by integrating differential privacy with federated learning. Yet caution is maintained regarding bias in generative models, the ethics of using synthetic data in healthcare, as well as the tradeoff between data fidelity and privacy. In this study we discuss the use of generative AI to create synthetic data for rare disease research, potential implications for privacy preserving analytics, ethical dilemmas, and future research. In this area, a scheme is designed to effectively utilize generative AI, resulting in a need for more innovation and interdisciplinarity. Through generative AI, in the coming years, synthetic data creation will transform how data can be shared securely and ethically, and efficiently for rare disease research while accelerating the development of new treatments, ultimately improving patient outcomes.

Heart failure (HF) is an important medical, social and economic problem. The study of new biological markers deepens our understanding of the pathogenesis of this disease. In modern cardiology, there is a growing interest in matrix metalloproteinases (MMPs). These enzymes play an important role in tissue remodeling, angiogenesis, as well as in cell proliferation, migration and differentiation.
The purpose of this literature review is to analyze current experimental and clinical data on MMP-9 as a new diagnostic and prognostic marker in HF. This review presents an analysis of modern publications on a given topic. We conducted an analysis of literature sources covering all important materials as of 01.12.2024. Experimental studies have established that MMP-9 is a key participant in cardiac remodeling, since it is directly involved in the degradation of extracellular matrix proteins and the activation of profibrotic pathways, as well as cytokines and chemokines. Clinical trial data indicate the significant importance of MMP-9 for diagnosis and prognosis in patients with HF.
Aftershocks on the Planar Rupture Surface of the Deep-Focus Mw 7.9 Bonin Islands Earthquake
Authors: Zhang Hao , Vidale John E. , Wang Wei
Published: January 2025

The largest deep-focus earthquakes typically occur in isolated settings, making their aftershock sequences crucial for understanding the interaction between these deep events, the subducting slabs, and their surroundings. The exceptionally deep Mw 7.9 Bonin Islands earthquake, which occurred at a depth of 680 km in a region previously thought to be aseismic, provides a rare opportunity to investigate the behavior and mechanism of deep earthquakes. Using an array-based beamforming technique, we flag numerous false detections in previous work, detect additional aftershocks following the Bonin Islands earthquake, and relocate using backprojection. The aftershocks are located outside the mainshock rupture zone and are aligned along a plane that extends from the mainshock rupture, suggesting a deformation migration across a pre-existing zone of weakness. These observations are compatible with the hypothesis of a thin metastable olivine wedge within the lower part of the Izu–Bonin slab, which may play a role in the deep earthquake mechanism. We reject a previous claim of deeper aftershock activity within the lower mantle. Our results further the understanding of the structure of the mantle and the physical mechanisms driving deep-focus earthquakes.
Status and Prospects for Research on Slovak Propaganda and Information Policy with Regard to the Crisis in Polish-German Relations and Invasion of Poland (October 1938–December 1939)
Authors: Segeš Dušan
Published: January 2025

The paper explores several thematic areas. The first focuses on the political and diplomatic relations between Czechoslovakia (also known as Czecho-Slovakia), Germany, and Poland. After March 14, 1939, the discussion shifts to the relationships between the Slovak State (Slovenský štát), Germany, and the Second Polish Republic. This section will cover the development of Slovak-German relations, starting from the period of Slovak autonomy (Slovenská krajina). It will also examine the negotiations and implementation of the Third Reich's demands in various aspects of political and social life in Slovakia, including German-Slovak actions against Poland.

The second area will focus on a historical analysis of the decrees, laws, decisions, organizational activities, and other factors that shaped the information policy of the Slovak State. The evaluation will include considerations of information policy, especially propaganda, discussing its content and mechanisms. This will be contextualized within a broader, though specific, analysis of the political regime in Slovakia.
Assessment of Western Farmers’ Use, Knowledge, and Acceptance of Cover Crops
and the Agri-Environmental Schemes That Support Their Use
Authors: Golden Lauren
Published: January 2025

Agri-environmental schemes (AES), which pay farmers to adopt conservation
practices, are increasingly important environmental and agricultural policy
tools. Despite large budgetary shares allocated to these programs, studies
identify lower-than-expected environmental outcomes. In the U.S. reasons for low
environmental outcomes include low participation rates, lack of program
awareness, and poor targeting levels. The Environmental Quality Incentives
Program (EQIP), the largest conservation program in the U.S. highly promotes
cover crops, as this practice has many benefits to water, air, and soil quality.
The Western U.S.is a large cropping region where data on cover crop use and AES
participation are lacking. Using a survey of Western U.S. farmers, this paper
provides an analysis on use of cover crops, awareness, and participation in
cover crop AES. Based on the results of 894 survey responses, we find most
respondents use or have used cover crops, with the highest motivators being the
soil health benefits and reducing soil erosion. The top barriers to cover crop
use are costs and lack of knowledge. Using a logistical regression, the
predictors of cover crop use in the West include larger farm size, regular
access to agriculture-related information, and perception of more benefits than
barriers to cover crops. For AES, the survey indicates that participation is low
due to lack of awareness and policy barriers. Predictors of AES participation
include frequent contact with NRCS, having a succession plan, and a positive
attitude toward governments’ role in conservation programs. This study informs
future research on cover crop use and policy design that influence adoption of
conservation practices.
Doxorubicin-Induced Changes to the TGF-β Signaling Pathway and Autophagic
Flux in Fibroblasts
Authors: Patricelli Conner
Published: January 2025

Doxorubicin is a commonly used chemotherapeutic used to treat many different
types of cancer. However, its clinical use is limited due to its cardiotoxic
adverse effects. While multiple mechanisms have been shown to be responsible for
doxorubicin-induced cardiotoxicity, it is generally accepted that the principle
mechanism is oxidative stress induction through the production of reactive
oxygen species and free radicals in the myocardium. However, efforts to
reduce/prevent doxorubicin toxicity using antioxidants have largely failed in
pre-clinical and clinical trials. The targeted approach using a liposome
delivery of doxorubicin significantly reduced the risk of cardiotoxicity;
however, this approach is limited to solid tumors and not cancer that has
metastasized. Therefore, continued research into doxorubicin-induced
cardiotoxicity and finding measures to counter this severe adverse effect
requires further investigation. Here we provide insight into how doxorubicin
affects cardiac fibroblasts in their proteome, extracellular matrix deposition,
and autophagic activity. Cardiac fibroblasts play a crucial role in the heart
such as synthesizing and depositing the cardiac extracellular matrix,
maintaining normal cardiac function, and cell-cell communication between other
fibroblasts, myocytes, and endothelial cells, which affect the
electrophysiological properties of the heart, and the secretion of both
cytokines and growth factors. To study the effect of doxorubicin on cardiac
fibroblasts, we took a multifaceted approach first by screening the cardiac
fibroblasts' proteome using tandem mass spectrometry techniques on primary
cardiac fibroblasts treated with doxorubicin for 24 hours. These findings
elucidated that doxorubicin-induced cardiotoxicity may be attributed to damage
in cardiac fibroblasts. Downregulation of cellular communication network factor
2 was detected through mass spectrometry which led to an in vitro study on how
doxorubicin affects cellular communication network factor 2 activity in cardiac
fibroblasts using immunoblotting techniques and reverse transcriptase polymerase
chain reaction. Lastly, we determined if autophagy was affected by doxorubicin
treatments with immunoblotting and reverse transcriptase polymerase chain
reaction. No significant changes in autophagy protein markers and gene
expression were observed in primary cardiac fibroblasts following doxorubicin
treatment, indicating that doxorubicin may not play a role in regulating
autophagy in cardiac fibroblasts.
Preservice Teachers’ Self-Efficacy for Technology Integration and Levels of
Planned Technology Integration
Authors: Portaro Marielle
Published: January 2025

Teacher education programs have a responsibility to prepare preservice teachers
for the demands of teaching, including how to integrate educational technology
into lessons. The purpose of this explanatory sequential mixed methods approach
study is to understand the relationship between preservice teachers’
self-efficacy for technology integration and their level of planned technology
integration. Self-efficacy is the belief in one’s ability to complete a task and
self-efficacy for technology integration is specific to teacher’s beliefs in
their ability to integrate technology in their lessons.

Participants in this study were 9 preservice teachers who were enrolled in a
university-based preservice teacher education program and concurrently
completing their student teaching practicum requirements. Self-efficacy for
technology integration was measured with the Computer Technology
Integration Survey (CTIS). Level of planned technology integration
was measured by scoring preservice teachers’ lesson plan documents using the
Triple E Evaluation Rubric. A subset of six participants
were interviewed about their perceptions of the aspects of their preservice
teacher education program which contribute to their self-efficacy for technology
integration and level of planned technology integration. Qualitative data was
analyzed using multiple coding cycles.

No conclusion could be drawn regarding the relationship between self-efficacy for
technology integration and level of planned technology integration. Participants
perceived that hands-on, mastery experiences with technologies related to the
content area they teach, and additional instruction on technological pedagogical
knowledge (TPK) in their preservice teacher education program,
would help them improve their self-efficacy for technology integration and level
of planned technology integration.
Comparison of Properties and Fracture Patterns in Aged and Fresh Cortical Bone
Authors: Roan McKenna
Published: January 2025

Bone is a complex natural material that presents many challenges to researchers interested in characterizing its mechanical properties. There are different techniques, such as drying, embalming, and freezing, to preserve bones for engineering and scientific study. There are advantages and disadvantages to these techniques, and there have been limited studies comparing the effect of preservation techniques on the mechanical and fracture properties. In this research, aged and fresh bovine bone specimens are tested in compression while monitoring acoustic emissions (AE). Three main aspects of testing are investigated: the force-displacement curves, acoustic emission activity, and fracture patterns observed in X-ray computed tomography (CT) scans.

Before compression testing, the ends of each bone specimen were potted in epoxy, CT scanned, encased in heat-shrink plastic, and an acoustic emission sensor was mounted to each specimen. During compression testing, force-displacement data is collected and synchronized to acoustic emission data. The tested bone specimen were CT scanned.

Pre-test CT scans showed that aged bones contained fractures that were produced by the aging (bleaching and boiling) processes. Aged bone specimens had higher failure forces and higher apparent stiffness values. The force-displacement curves show that aged bone specimens have a more brittle behavior. Aged bone specimens had greater numbers of acoustic emission events than fresh bone specimens. The AE events in fresh bone specimens were associated with lower energy and higher average frequencies. Acoustic emission events occur in aged bone specimens well before they occur in fresh bone specimens. In some instances, no acoustic emission event occurred until failure in fresh bone specimens. Post-test CT scans revealed that aged bone specimens had large multifragmentary fractures that propagated through the entire length of the specimen. The fractures produced in fresh bone specimens were contained within the lower and upper twenty percent of the specimen. The fresh bone specimens had circumferential fractures that were not observed in the aged bone specimens. These fractures were contained between the inner and outer dense cortical bone veneer of the specimens.

The data generated and presented show there is a clear difference in the behavior of aged and fresh bone specimens. These differences are demonstrated by force-displacement curves, acoustic emission data, and fracture types identified in CT scans. Deformation properties between fresh and aged bone specimens presented a clear distinction between the microcracks and crack propagation between fresh and aged bones. Overall, each aspect of this research showed clear differences in the failure behavior of fresh and aged bones. Although aged bone specimens and fresh bone specimens have less stringent handling and storage requirements than fresh bone specimens, these two specimen types have different mechanical and fracture properties.
Stressed and Shopping: Examining Social Media-Induced Stress and Online Impulsive Buying in Gen Z

Published: January 2025

This study investigates how social media-induced stress influences online impulsive buying behavior among Gen Z consumers within a social commerce context. It further explores the mediating role of negative coping strategies and the moderating effect of self-control. Data was collected through online questionnaires targeting 300 Gen Z respondents selected via purposive sampling criteria, then analyzed using conditional process analysis with SPSS macro-PROCESS. Findings confirm that social media-induced stress, directly and indirectly, triggers impulsive buying through negative coping. Additionally, self-control significantly moderates this relationship, wherein lower self-control intensifies the effect of stress on impulsive buying. This research addresses gaps in the literature by highlighting the role of negative emotions, specifically stress, in driving consumer behavior. Findings contribute valuable insights into evolving digital consumerism patterns among Gen Z, emphasizing the need for self-control in digital environments while also highlighting how negative coping acts as the mechanism that channels stress into impulsive buying behavior.
Intraovarian platelet-rich plasma injection: a potential path to genetic parenthood for women with low ovarian reserve
Authors: Kaul Nalini
Published: January 2025

Background: The incidence of women with low ovarian reserve (LOR) presenting for ART is increasing. Infertility management is challenging since oocyte numbers are related to IVF success. The use of intraovarian platelet rich plasma (IOPRP) is emerging as a promising technique for ovarian rejuvenation. This study evaluates role of IOPRP in improving ovarian reserve markers, ovarian response and reproductive outcomes in women with LOR keen to achieve genetic parenthood.
Methods: This prospective observational cohort study was done on 85 women of Indian ethnicity 25-50 years, Poseidon group 3 and 4, infertility >3 years wih at least 1 previous IVF failure. One ml of PRP prepared by double centrifugation technique was injected into each ovary transvaginally. AMH, AFC, FSH, ovarian response measured pre and post IOPRP.
Results: At 8 weeks post PRP a statistically significant increase in AMH (0.57±0.33 ng/ml vs 0.96±0.49 ng/ml p<0.001), AFC (4.11±1.81 vs 7.81±3.35 p<0.001), number of oocytes retrieved (3.29±2.22 vs 5.52±3.66 p<0.001) and number of usable embryos (1.11±1.21 vs 2.33±2.12, p<0.001) was seen. Of women who underwent IVF 57.1% achieved clinical pregnancy. Overall Live birth rate was 38.09%, 8 women conceived without IVF with a live birth rate of 40%.  Poseidon group 3 showed a greater improvement.
Conclusions: The study suggests that IOPRP treatment increases ovarian reserve markers and response and may be a viable alternative to donor oocytes in women with LOR wanting genetic parenthood.
