ULOGA I ZNAČAJ DIGITALNE TEHNOLOGIJE U OBRAZOVANJU
Authors: Hasanbašić Esma
Published: February 2025

U ovom radu otvaraju se odreĎena pitanja vezana za implementaciju digitalne tehnologije u škole, a time i nastavu. Posljednjih desetljeća svjedoci smo ubrzanog razvoja računalne tehnologije i drugih tehnologija. Razmjena i transformacija znanja putem informacijskih tehnologija postale su obiljeţja modernog društva. Razvojem tehnologija mijenja se okruţenje u kojem učenici razvijaju vještine koje su im potrebne za ţivot. Digitalno zreli učitelji svjesni su da je cilj implementacije IKT-a u škole poticanje usvajanja znanja, motivacije, angaţmana učenika i boljeg razumijevanja nastavnog sadrţaja. Primjena IKT-a u učenju i poučavanju podrazumijeva paţljivo odabrane digitalne sadrţaje koji odgovaraju kontekstu nastavnog predmeta i nastavnim aktivnostima. Krajnji cilj integracije tehnologije u nastavu je da se redefiniraju načini podučavanja i učenja, i da se u nastavi radi ono što se nikada prije nije moglo jer je nedostajala digitalna tehnologija. Ovaj rad predstavlja pokušaj da se ukaţe na nastanak nove kulture učenja potpomognute razvojem digitalne tehnologije.
UTICAJ STUBOVA KONKURENTOSTI – FAZA FAKTORA NA BRUTO DOMAĆI PROIZVOD U BOSNI I HERCEGOVINI U PERIODU 2010–2016.
Authors: Savanović Nebojša , Savanović Slobodanka
Published: February 2025

Napravili smo empirijsko istraživanje o postojanju veze između bruto domaćeg proizvoda i pojedinih stubova konkurentnosti. Empirijske studije koje su uobličile period nakon globalne ekonomske krize mogle bi doneti zanimljive zaključke sa ekonomskog stanovišta. Stubovi konkurentnosti u ovom istraživanju su nezavisno varijabilni, izraženi kao elementi Globalnog indeksa konkurentnosti (GCI) i definisani od strane Svetskog ekonomskog foruma (WEF), a zavisna varijabla je bruto domaći proizvod. Problem istraživanja odnosi se na korelaciju između kretanja bruto domaćeg proizvoda u Bosni i Hercegovini u periodu od 2010. do 2016. godine i stupova  konkurentnosti, osnovnih uvjeta, podindeksa: institucije, infrastruktura,  makroekonomsko okruženje. Glavni rezultat istraživanja je taj da je veoma mali uticaj na BDP za prva dva podindeksa konkurentnosti, dok u trećem, makroekonomskom okruženju, kad je u pitanju ovaj nivo razvoja zemlje, gotovo da ne postoji.

Authors: Fulgencio Leopoldo
Published: February 2025

Neste artigo, pretende-se analisar os diversos usos do termo e do conceito de paradigma para o estudo da psicanálise. Após esclarecer qual é o sentido e as características desse conceito, tal como propôs Thomas S. Kuhn, analisa-se como diversos autores, psicanalistas e filósofos, utilizaram com mais ou menos rigor o termo kuhniano. Considera-se que as noções de paradigma, léxico, incomensurabilidade, crise e revolução podem servir para a comunicação e o diálogo entre as diversas perspectivas teóricas da psicanálise, num momento em que diversos autores estão de acordo em reconhecer que há uma crise de comunicabilidade e de desenvolvimento da psicanálise.

Authors: Chaboud Alain , Correia Golay Ellen , Cox Caren , Fleming Michael J. , Huh Yesol , Keane Frank M. , Lee Kyle , Schwarz Krista , Vega Clara , Windover Carolyn
Published: February 2025

Although the U.S. Treasury market remains the deepest and most liquid securities market in the world, several episodes of market dysfunction over recent years have brought the market’s resilience into focus. The adoption of all-to-all trading in the Treasury market could be one avenue to strengthening market resilience. Conceptually, all-to-all trading would allow any market participant to trade directly with any other market participant. This could be helpful in times of stress when the capacity of traditional intermediaries may be tested. In this article, we discuss what all-to-all trading would mean for the Treasury market, the benefits it might bring, and what can be learned from the experience of other markets. We also review several trading protocols operating in the Treasury market that widen the field of trading partners and discuss the challenges to the broader use of such protocols or to the adoption of new all-to-all protocols.
Depicting Cultural Clash and Quest for Identity in Hari Kunzru's The Impressionist
Authors: Dohshoush Yahya Ali Mohammed , Alburaihi Ibrahim Sufyan Qassim Hajib
Published: February 2025

The paper interrogates race, identity, and hybridity in The Impressionist as legacies of colonialism. It uses the post-colonial approach to discuss these related topics. It deals with the cultural clash between the colonizer and the colonized and the quest for identity in the postcolonial era. It shows how hybridity and diasporic experiences affect the protagonist's attempt to construct his identity. It argues how the protagonist's attempts to construct his identity are hampered by the incongruous cultural values crammed in his mind by the colonizer's indoctrination. It argues that through depicting the cultural clash between the colonizer and colonized, dismantles the racist indoctrination that prompts Indians to ape the colonizers' culture and internalize the British values. Through portraying the protagonist's predicaments and the horrendous incidents the protagonist has undergone, Kunzru challenges the oppressive power structures inherited in Indian society. He also attempts to expunge the nefarious impact of colonialism that maims Indian identity in the post-independence era and entangles Indians in its snare. Kunzru has denuded his protagonist, Pran Nathan, of the definite boundary of society, home, nation, and individuality and provoked him to embrace fake identities. Through, Kunzru stresses the importance of blurring and intermingling identities and boundaries into a single identity and boundary but he himself has encountered some challenges that have impeded achieving his dream in the foreign countries.

Wahlkreissieger ohne Bundestagssitz?
Authors: von Ungern-Sternberg Antje
Published: February 2025

Nachdem das neue Wahlrecht am Sonntag zum ersten Mal praktisch zur Geltung kam, wundern sich zahlreiche Beobachter über die praktischen Folgen für die „Wahlkreisgewinner“, die mangels Zweitstimmendeckung nicht in den Bundestag einziehen dürfen. Diese Folgen sind bei näherer Betrachtung zwar nicht überraschend, lassen aber durchaus die Überlegung zu, ob etwaige Nachteile dieses Wahlrechts durch eine Reform beseitigt werden können – zumal Friedrich Merz ohnehin schon angekündigt hat, das Wahlrecht ändern zu wollen.

Exploring Backbone Network Choices in FCOS3D: Performance and Efficiency Analysis
Authors: He Linyi
Published: February 2025

This study presents a comparative analysis of the performance of two modified object detection models, FCOS-Swin and FCOS-ConvNeXt, against the FCOS3D baseline model using the nuScenes dataset. The study evaluates the models based on their classification results for various categories of objects and on multiple evaluation metrics. We compare FCOS-Swin and FCOS-ConvNeXt, which utilize different backbone architectures, to evaluate their effectiveness in 3D object detection. Results show that the modified models exhibit comparable performance with slight variations in all metrics compared to the baseline, but fall short of the fine-tuned FCOS3D model. Potential reasons for this performance gap, including model parameter size, data augmentation methods, learning rate settings, and training epochs, are discussed. This study also explores possible improvements and future work, such as switching to larger backbone models, utilizing stronger data augmentation techniques, adjusting the learning rate method, increasing training epochs, and incorporating temporal and spatial logic to optimize model performance.

An Introduction to Eventown and Oddtown Problem
Authors: Huang Yixuan
Published: February 2025

The Eventown and Oddtown problem is a classic in Extremal Combinatorics, a field that examines set systems under specific constraints related to the relationships between sets and their elements. Tackling such problems is crucial as it involves decomposing complex issues into fundamental components, thus facilitating a transition from intuitive understanding to formal mathematical reasoning. Specifically, the Eventown problem centers on a scenario where 32 residents of a town aim to form groups, each containing an even number of members. The challenge lies in determining the maximum number of these groups. Rooted in abstract set theory and combinatorial techniques, this problem exemplifies the intricate connection between intuitive concepts and rigorous mathematical formalism, underscoring its significance in the realm of Extremal Combinatorics.

An Experiment of Implementing Reservoir Sampling to StreamingLLM
Authors: Pan Jiyang , Weng Jiayi , Huang Yansen , Pan Patrick , Zhao Qianbiao
Published: February 2025

When the text is longer than the training sequence length, the streamingLLM can successfully improve the computational speed and guarantee a certain degree of accuracy. But this method is only suitable for short term memory questions and answers. Because the StreamingLLM doesn’t improve a computer’s Long-term memory ability. We tried to combine the reservoir sampling with streamingLLM. Since StreamingLLM, the reservoir sampling will randomly take samples from what were meant to be discarded. Through adding reservoir sampling, we find the results are more accurate and representative.

Should Therapists Pay More Attention to Sensory Processing Sensitivity in Individuals with Depression?
Authors: Pu Chuanqi
Published: February 2025

Ever since the concept of Sensory Processing Sensitivity (SPS) was introduced, extensive research has solidified its theoretical and empirical foundations. SPS is characterized by enhanced awareness, deeper information processing, and increased emotional and physiological reactivity (Acevedo, 2020). Moreover, research has found that a significant portion of 20-30% of the population exhibits high SPS (Greven et al., 2018). The prevalence of SPS becomes particularly concerning for increasing the likelihood of individuals developing depression. Studies indicate that individuals with high SPS are more susceptible to depressive symptoms under stress (Wu et al., 2020). High levels of sensory processing sensitivity might be related to the appearance of depression. This raises critical questions about current therapeutic practices: Do therapists consider SPS when diagnosing depression? Should treatment protocols differ for patients with both depression and high SPS compared to those without SPS? This literature review aimed to explore the relationship between SPS and depression and how therapists might leverage this understanding to refine diagnostic and treatment methods for individuals with high SPS. To examine potential ways to ensure that SPS is appropriately considered in depression diagnoses, this review also compared and contrasted diagnostic methods for individuals with high SPS and those with depression. Furthermore, the review explored possible alternative treatments that could be used or developed specifically for individuals with high SPS and depression.
Research on adaptive filter of Orthogonal Frequency Division Multiplexing Signals Based on LMS Algorithm
Authors: Yu Haocheng , Yang Zhilin , Lin Yuliang
Published: February 2025

This research focuses on processing signals in orthogonal frequency division multiplexing (OFDM) systems, especially adaptive filter techniques for multipath effects and noise interference. By deeply discussing the application of the LMS algorithm in the OFDM system, this paper proposes an adaptive filter scheme founded upon the LMS algorithm, which adaptively changes filter parameters to increase signal transmission efficiency and speed. The principles of the LMS algorithm and that of the adaptive filter, as well as the applicability and performance of the filter in the OFDM system, are analyzed and studied. Simulation experiments are conducted by MATLAB for the purpose of verifying the efficiency of the proposed scheme in reducing signal interference and improving system performance. The results indicate adaptive filter technology founded upon LMS algorithm has a wide application prospect in OFDM system, and plays a strong support for the development of wireless communication technology.
Simple Linear Regression Analysis with Non-Normal Errors
Authors: Wang Yinhao
Published: February 2025

We consider a simple linear regression with non-normal errors; specifically, errors follow the double exponential distribution and uniform distribution. Maximum likelihood estimates for parameters (intercept and slope) are investigated. Although they do not have closed mathematical forms, they can be derived uniquely by numerical methods. Through Monte Carlo simulation, ordinary least square estimates (LSE) and maximum likelihood estimates (MLE) are derived and compared through their biases, variances and mean squared errors. Simulation studies show that both MLE and LSE follow normal distributions and MLE has smaller mean squared errors compared to LSE. This paper suggests or confirms that one prefers to use MLE to estimate unknown parameters if there exists strong evidence that errors do not follow a normal distribution.
Studying the factors that influence the Incidence of UCR Part One Crimes in Boston
Authors: He Yanxi , Xie Maomao , Lin Lei , Ding Taoyuan
Published: February 2025

Boston, as one of the most populated cities in the United States, while being known for its rich history, humanities and culture, also faces significant challenges with crime. This paper presents research on the critical factors that influence a possibility of a crime in Boston being UCR part 1 crime. If applied to law enforcement agencies, the distribution of police resources in Boston can be more reasonable and enable better urban security. We obtained the dataset from a Kaggle post, which was obtained from the Crime Incident Report of the Boston Police Department. By cleaning the data, converting months to seasons, we made the data more usable. We then split the data in a 70-30% ratio. We ran two models – first for the training session, we used the random forest classifier to identify the most significant factors. We evaluated the model by using metrics such as accuracy, precision, recall, and the ROC-AUC curve. In the testing session, we employed a logistic regression model for cross validation. For both models, the obtained accuracy is over 94%, indicating an extremely high overall performance for both models. Through the data analysis and test in this paper, it can be summarized that both the logistic regression model and random forest classifier can effectively predict and analyze an instance of a UCR part 1 crime in Boston based on the location of the crime, crime code group, season, time of the day, and day of the week. Though the accuracy is significantly high, we should not ignore the fact that we used a slightly older dataset ranging from 2015 to 2018, which, being six years ago, may have intrinsically different crime patterns than those that occur now.

This review examines currently available alternatives to fluorinated chemicals for durable water repellent (DWR) and stain-resistant products, focusing on environmentally friendly options. It evaluates commercial products made from silicones, hydrocarbons, and dendrimers, based on chemical structure, repellency mechanism, and manufacturer-provided test results. Silicones offer hydrophobicity comparable to fluorinated chemicals, along with good feel, breathability, and cost-effectiveness. Hydrocarbons are eco-friendly and provide sufficient waterproofing for general use but fall short in extreme conditions. Dendrimeric DWR offers durability and breathability but is expensive and challenging to apply. All non-fluorinated DWR products share a common limitation: lack of oil repellency. Beyond surface chemistry, alternative approaches to liquid repellency include liquid-like surfaces that achieve low contact angle hysteresis through surface mobility, and designing surface texture and geometry to maintain a Cassie-Baxter state for high contact angles. The review concludes by highlighting future challenges in the field, including the development of oil-repellent, cost-effective, large-scale manufacturing technologies that align with the goals of a circular and sustainable economy.

Inleiding
Het doel is om na te gaan of de gezondheidsmonitor Volwassenen en Ouderen (GM V&O) en de gezondheidsenquête (GE) voldoende betrouwbaar zijn voor beleidsbeslissingen over lengte en overgewicht bij 1-21 jarigen. 
 
Methode
Lengte en body mass index (BMI) van 21-jarigen uit de GM V&O uit 2012 en 1-20 jarigen uit de GE uit 1997, 2009 en 2010 zijn vergeleken met de groeireferenties van de vierde en vijfde landelijke groeistudies. De methodiek van data verzameling voor de GE verschilde in 2009 van die in 2010, hetgeen de reden was dat deze gegevens ook zijn geanalyseerd. 
 
Resultaten
Binnen de GM V&O data kwamen de gemiddelde en standaarddeviatie (SD) van lengte en BMI nagenoeg overeen met de groeireferenties. Binnen de GE data werd de lengte over het algemeen overschat en de BMI onderschat en was de spreiding hoog, met name bij jonge kinderen. Binnen de groeistudies zagen we binnen alle leeftijdsgroepen een toename in het percentage overgewicht tussen 1997-2009, terwijl dit binnen de GE data niet het geval was of minder sterk.
 
Beschouwing
De eindlengte en BMI zijn op jongvolwassen leeftijd  waarschijnlijk betrouwbaar te schatten met behulp van GM V&O. De GE data weken met name voor de jonge leeftijdsgroepen af en lijken hiermee geen betrouwbare informatie te geven over puntinschattingen en trends. Deze bevindingen werpen belangrijke vragen op over de betrouwbaarheid van zelf- of ouderrapportagegegevens bij kinderen en het gebruik hiervan voor beleidsdoeleinden.

The development of high-efficiency solar cells is of paramount importance for advancing sustainable energy technologies and meeting global energy demands. This study focuses on the optoelectronic performance of FTO/TiO2/Cs3Bi2I9/Spiro-OMeATAD/Ag planar heterojunction solar cells. Through detailed analysis, we investigated various factors such as crystallite size, strain, dislocation density, and their collective influence on the overall performance of the solar cells. Among the fabricated samples, sample A3 exhibited a significant improvement in efficiency, showing a 0.72% enhancement over the others. This increase is attributed to A3's superior crystallite quality, which led to reduced strain and a lower density of dislocations. These properties contribute to minimizing non-radiative recombination losses and enhancing charge carrier mobility, both of which are crucial for maximizing the photovoltaic performance of the device. These factors bring A3 closer to the theoretical Shockley-Queisser  (S-Q) efficiency limit, a benchmark for photovoltaic performance. Further analysis using SCAPS-1D simulations supported these experimental findings, demonstrating the significance of optimizing critical parameters such as the minority carrier lifetime. The simulations revealed that high losses in short-circuit current density (JSC) were a primary limiting factor in performance, emphasizing the need for careful tuning of these parameters to reduce losses. This work highlights the critical role of precise material engineering in developing highly efficient perovskite solar cells. The study not only provides insights into the structural and electronic properties essential for performance enhancement but also underscores the potential of Cs3Bi2I9 as a promising material for photovoltaic applications. The findings offer valuable guidance for the next generation of high-efficiency, low-toxicity, and lead-free perovskite solar cells, aligning with global efforts to transition to clean, renewable energy sources.
Aprendizaje basado en proyectos: Fortaleciendo habilidades blandas en educación superior

En el ámbito educativo contemporáneo, la búsqueda de metodologías que promuevan un aprendizaje profundo y significativo es una prioridad. Los enfoques tradicionales, caracterizados por la transmisión pasiva de cono-cimientos y la memorización de datos, han demostrado ser inadecuados para enfrentar los desafíos complejos del siglo XXI (Avilés et al., 2023). La mera acumulación de información ya no es suficiente en un mundo donde el acceso al conocimiento está al alcance de un clic. En su lugar, se requiere el desarrollo de habilidades, como el pensamiento crítico, la resolución de problemas, la creatividad y la capacidad de colaborar y comunicarse efectivamente. Este escenario ha impulsado la adopción de paradigmas pedagógicos centrados en el estudiante, donde el aprendizaje basado en proyectos (ABP) se destaca como una estrategia innovadora y conveniente (Barrera et al., 2022).
Educación intercultural sin la perspectiva del Estado
Authors:   Universidad Nacional Autónoma de México, Maldonado Alvarado Benjamín
Published: February 2025

Es común que la educación intercultural y la interculturalidad en general se miren y “realicen” desde la definición que de ellas tiene el Estado nacional, principalmente como un enfoque que debe lograr enseñar el respeto a la diversidad cultural. Precisamente para buscar caminos diferentes, en pos de objetivos contrastantes y distintos, se plantean las formas de interculturalidad crítica y de educación alternativa en el país y fuera de él.
Esta costumbre de pensar lo intercultural desde el Estado, es decir, desde una mirada afín a los intereses de dominación colonial que promueve y protege, hace que lo que podamos llamar “crítico” no lo sea tanto, pues significaría intentar entre otras cosas tratar de fortalecer la resistencia desde los intereses de la dominación.

Published: February 2025

El presente texto tiene el propósito de aclarar qué se entiende por los conocimientos y saberes tradicionales de los Pueblos Indígenas y su aplicación en la vida práctica y su relación con otro tipo de saberes. Esto se refiere a un diálogo de saberes entre la ciencia occidental y estos saberes tradicionales de los pueblos originarios de nuestro país, que muestran el mosaico pluriétnico y pluricultural que expresan la diversidad cultural que hay en México, así como su relación con la gran biodiversidad debido a la existencia de las diferentes regiones ecológicas.
Para preservar y rescatar el conocimiento y los saberes tradicionales de los pueblos originarios y campesinos, han surgido una serie de corrientes o disciplinas científicas llamadas etnociencias como son la etnobotánica, la agroecología, la etnociencia, la etnobiología, la etnoecología y recientemente la etnoagronomía, que tratan de sistematizar, desde su propia perspectiva, la importancia que tienen estos conocimientos y saberes para la ciencia y la cultura occidental. Se trata del estudio científico de estos conocimientos y saberes tradicionales para conservarlos y desarrollarlos, para bien del conocimiento occidental y para los propios generadores de estos conocimientos que son principalmente los pueblos originarios.

Published: February 2025

This research presents a cross-correlation similarity matching method to study the fingerprint transformation and thresholding impact. This work directly compares the impact of various transformations (rotation, translation, elastic deformation, and scaling) on the fingerprint matching performance at different threshold values, in contrast to the standard minutiae-based systems. In order to compare the template positions of the two fingerprints using plots, the cross-correlation similarity matching of fingerprints first selects suitable templates in the primary fingerprint and then uses template matching to assess the impact of each transformation on matching accuracy, FRR, and FAR in the secondary print. The findings highlight the potential of thresholding in developing reliable and practical fingerprint recognition systems.

The use of ICT in secondary education presents challenges that hinder its effective implementation. These challenges include inadequate time management, excessive dependence on technology, and the lack of a committed approach both in the family environment and in educational institutions. These difficulties hinder the acquisition of digital competencies and limit their transformative potential in the educational process, so it is essential to address these barriers in order to take full advantage of their educational value and promote meaningful and critical learning in secondary education students especially in mathematics training. In this framework, the main objective of the research was to analyze the relationship between the metric spatial component and different dimensions of the use of information technologies. For this purpose, a research was carried out under the quantitative approach, with a non-experimental design, of descriptive correlational scope, in which measurements of both variables were implemented in a sample of 67 seventh grade students of the secondary level from different educational institutions of the municipality of Boyacá. The results indicate a statistically significant correlation between both variables.
