Authors: Aksyonov Igor
Published: February 2025

The study has been conducted at the Education-Scientific Institute of Natural and Agrarian Sciences of Lugansk National University named Taras Shevchenko (Ukraine). The research was aimed at establishing the elements of agricultural technology that ensure the maximum yield of pure seeds of sterile analog of the maternal lines GE6A and GE57A when grown under group isolators. This study examined the structure of plant productivity of sterile analog when grown under group isolators with a width of row spacing of 70 and 45 cm, with a plant population of 40, 50, 60, and 70 thousand plants ha-1. The created conditions for growing plants under group isolators had different effects on the development of the vegetative mass of plants and quantitative characteristics of the productivity of plants of lines. A width of row spacing and crop density statistically influenced (P < 0.05) the formation of quantitative traits of plant productivity of maternal lines. Growing lines with a width row spacing of 45 cm at a plant density of 40-60 thousand ha-1 ensured an increase in the weight of head seeds in the sterile analog of the maternal line GE6A by 3.7-5.8 g, in the sterile analog of the maternal line GE57A - by 4.2-6.2 g. Each maternal line had an individual reaction to changes in growing conditions. A width of row spacing of 45 cm and a sowing density of 50 thousand plants/ha ensured the highest pure yield of seeds from a sieve with a hole size of 2.5 × 20 mm from one isolators of 16.0 kg and a maximum yield of 1.69 t ha-1 for the sterile analog of the maternal line GE6A. A width of row spacing of 45 cm and a sowing density of 50-60 thousand plants/ha ensured the highest pure yield of seeds from a sieve with a hole size of 2.5 × 20 mm from one isolators of 14.7-14.8 kg and a maximum yield of 1.55-1.57 t ha-1 for the sterile analog of the maternal line GE57A. The sterile analog of the maternal line GE6A, with a maximum yield level at a width of row spacing of 45 cm, produced a higher yield of 0.14-0.12 t ha-1 than the sterile analog of the maternal line GE57A. The research results allowed us to recommend the use of agricultural technology elements individually when growing maternal lines under group isolators.

Published: February 2025

A reciclagem é uma maneira de reaproveitar e diminuir a quantidade de resíduos que são descartados. É
importante que ações sejam realizadas a fim de incentivar a população a reciclar. A educação realiza um
papel fundamental na conscientização do descarte correto dos resíduos. Nas escolas, várias iniciativas vêm
sendo realizadas para que estudantes percebam que o ato de reciclar está diretamente relacionado com o
futuro do Planeta. Jogos educacionais podem ser aliados nesse processo de ensino porque conectam o
entretenimento e a aprendizagem. Porém, observa-se que, em geral, a maioria dos jogos educacionais
disponíveis, dos mais variados temas, não são desenvolvidos para pessoas com deficiência intelectual, as
quais requerem uma prática educacional diferenciada. Este artigo apresenta o desenvolvimento do jogo
educacional denominado de My Clean Park destinado a pessoas com deficiência intelectual. O jogo aborda
a temática reciclagem em que o jogador deverá passear por um parque e coletar itens do chão que podem
ser recicláveis. Com ajuda de uma agente inteligente, o jogador deverá depositar esses itens coletados nas
lixeiras corretas.

Published: February 2025

Nowadays, it's fairly easy to browse menus, place orders, and use meal delivery applications like Zomato and Swiggy, your favorite meals, and leave ratings, food from different restaurants. These ratings and reviews are helpful not just for customers but also for businesses. However, figuring out the overall sentiment from these reviews can be tricky. To better understand the data, we did some exploratory analysis to identify the most and least expensive restaurants. We also found the top critics—those with more than 100 reviews and 10,000 followers. We then used clustering methods like KMeans and Hierarchical clustering to be grouped restaurants into three categories based on their cuisine type and pricing. For sentiment analysis, we tried both supervised methods (like Logistic Regression, Decision Trees, and Naive Bayes) and unsupervised methods (like Linear Discriminant Analysis). We defined ratings above 3.5 as positive. After some fine-tuning, we found that Logistic Regression and LightGBM worked the best.

Published: February 2025

Vaccination is one of the methods to control and prevent the spread of infectious diseases. SIR model (susceptible, infected, recovered) without and with vaccination were developed. The behavior of the solutions of the two models is analyzed through stability analysis around the equilibrium points. The stability is also associated with a threshold number indicating the population is free or infected. Analytical results are confirmed with numerical results that are presented on the graphic solution and phase portrait. The results of numerical simulations conclude that vaccination is more effective for inhibiting the transmission of the disease than without vaccination

Authors: Harianto Joko , Suparwati Titik , Sari Inda Puspita
Published: February 2025

This article is included in the scope of mathematical epidemiology. The purpose of this article is to describe the dynamics of the spread of disease with some assumptions given. In this paper, we present an epidemic SVIR model with the presence of immigration in the vaccine compartment. The analysis of equilibrium point stability discussed only local stability. First, we formulate the SVIR model, then the equilibrium point is determined, furthermore, the basic reproduction number is determined. In the end, the stability of the equilibrium point is determined depending on the number of basic reproduction. The result is that if the basic reproduction number is less than one then there is a unique equilibrium point and the equilibrium point is locally asymptotically stable. This means that in those conditions the disease will tend to disappear in the population. Conversely, if the basic reproduction number is more than one, then there are two equilibrium points. The endemic equilibrium point is locally asymptotically stable and the disease-free equilibrium point is unstable. This means that in those conditions the disease will remain in the population

Published: February 2025

Quantile regression as a robust regression method can be used to overcome the impact of unusual cases on regression estimates such as the presence of potential outliers in the data. The purpose of this study was to evaluate the effectiveness of quantile regression in dealing with potential outliers in multiple linear regression compared to ordinary least square (OLS). This study used simulation data in multiple regression model with the number of independent variables (p=3) for different sample sizes (n = 20, 40, 60, 100, 200) and   and  repeated 1000 times. The effectiveness of the quantile regression method and OLS in estimating Î²   parameters was measured by Mean square error (MSE) and the best model is chosen based on the smallest Akaike Information Criterion (AIC) value. The results showed that in contrast to OLS, quantile regression was able to deal with potential outliers and provided a better estimator with a smaller mean mean square error. Compared to OLS and other quantiles, this study also provides sufficient results that quantile 0.5 provides the best parameter estimate and the best model based on the smallest MSE and AIC values.

The increase in air temperature due to climate change and global warming has become a major concern for policy makers, one of which is the government of East Kalimantan. Electric energy consumption has a close relationship with economic development in East Kalimantan. So it is necessary  to forecast the temperature of air in order to predict the consumption of electrical energy in the future. The purpose of this study was to determine the forecasting of air temperatures in East Kalimantan, namely the cities of Balikpapan, Samarinda and Berau and to determine the relationship between air temperature and electricity consumption in East Kalimantan. In this study, the method used is the ARIMA (Autoregressive Integrated Moving Average) and multiple linear regression methods. The results of the analysis using the ARIMA method obtained the best models for the cities of Balikpapan, Samarinda and Berau respectively, namely ARIMA(1,1,1), ARIMA(1,1,1) and ARIMA(3,1,0). Based on the results of multiple linear regression obtained R-square value of 39%, which mean that the influence of air temperature on the consumption of electrical energy is 39%. From the results of the t test and F test, it is known that air temperature has a significant effect on the increase in electricity consumption in East Kalimantan
Anthropological risks of artificial intelligence and GPT neural networks
Authors: Skorodumova Olga Borisovna , Matronina Lilia Fedorovna
Published: February 2025

The rapid increase in the role of science, technology, and engineering in the modern world, including the development of artificial intelligence and GPT neural networks, has contributed to the actualization of research into both these areas and the new opportunities and risks they generate. The purpose of this study is to identify the impact of modern technologies, specifically artificial intelligence and fourth- and fifth-generation GPT neural networks, on human physical and mental health, spiritual qualities, and their implications for new global risks, primarily anthropological ones. The article emphasizes that a powerful techno-anthropological shift is being observed worldwide, the consequences of which are impossible to predict. The digital revolution has given rise to a new goal – the “upgrade” of humanity. It is no coincidence that anthropological risks have become a problem-oriented research area. The scientific novelty of this research lies in its disclosure of the main objective and subjective factors that influence the transformation of the human personality and its conversion into a “post-human.” The study found that the development of artificial intelligence systems and related GPT neural networks creates the prerequisites for the targeted formation of personality by network platforms, which poses the threat of unpredictable consequences. It concludes that there is a need to develop social mechanisms and applied pathways aimed at overcoming the anthropological crisis.
The policy of the city public administration of Yekaterinburg in the sphere of searching for new sources of funding (1905-1914)
Authors: Yaroma Olga Vladimirovna
Published: February 2025

The aim of this work is to analyze the financial policy of the Yekaterinburg city self-government in the area of searching for new sources of income from 1905 to the first half of 1914. The choice of Yekaterinburg is due to the fact that it was the largest district town of the Perm Governorate, whose capabilities were quite comparable to the provincial capital Perm in the sphere of municipal budget formation. The article examines the ways in which the Yekaterinburg city self-government sought to replenish municipal finances. A number of such methods are identified that were characteristic of the city from 1905 until the beginning of the First World War, their correspondence to the all-Russian course of development of local self-government. The policy of the Yekaterinburg city authorities in raising funds is compared with the policy of the Perm city authorities, which allows us to demonstrate the difference in the capabilities of a provincial and a district, albeit the largest, city. The state of the municipal budget is analyzed. The public administration of the city, in order to improve the financial situation, tried to introduce new taxes and levies, maximize the exploitation of municipal property and enterprises, and use the concession method of attracting funds. The main source of attracting additional funds was municipal loans. Yekaterinburg, as a large, high-budget city, despite its district status, could make them, which brought it closer to the provincial capital. The scientific novelty of the research lies in the fact that individual facts about the activities of the Yekaterinburg city self-government are published for the first time, and the history of the city's finances is considered for the first time in the focus of finding new sources of income. As a result of the research, the author concludes that the financial policy of the Yekaterinburg city authorities, on the one hand, corresponded to all-Russian trends, and on the other hand, had its own specifics.
Geography of Russia in the landscape works of the contemporary Chinese artist Wang Tieniu
Authors: Xiong Peihan
Published: February 2025

The aim of the article is to analyze and interpret the landscape works of Wang Tieniu, created by him in Russia, with a discussion of cultural integration and his artistic contribution to contemporary art. The article examines Wang Tieniu’s landscape works created during his studies in Russia, as well as his sketches made during his mature period of creativity in places such as Suzdal, Pushkinskiye Gory, Khabarovsk, Kamchatka, and other regions. The novelty of the research lies in the fact that it presents a comprehensive analysis of the artist’s landscape works for the first time. As a result, the article reveals that Wang Tieniu’s creative style is based on quick and lively brushstrokes, a unique application of color, and diverse compositional approaches. He masterfully extracts the patterns of nature and uses them in the construction of the composition, for example, the concept of yin and yang from natural phenomena. His studies of natural laws and deep feelings for Russian literature are reflected in his works, giving the paintings a sense of “friendliness”. Wang Tieniu’s works have a memorial character, capture the geographical and cultural features of Russia, and contain deep emotions and philosophical reflections, which gives them significant artistic value. The article examines the problem of the mutual influence of Chinese and Russian art through the example of Wang Tieniu’s work, such as the combination of the Chinese technique of “freehand drawing” with Russian oil painting. Also important is the assessment of the influence of Chinese philosophy and culture on the creation of landscape images of Russia in Wang Tieniu’s work.
The embodiment of German Expressionism on the stage of the Bolshoi Drama Theater: K. P. Khokhlov’s production of “Gas” based on G. Kaiser’s play (1922)
Authors: Pavlova Natalia Gennadevna
Published: February 2025

The study aims to reveal the peculiarities of the perception of German Expressionist drama by the Soviet theater of the 1920s-1930s, using the example of K. P. Khokhlov’s production of “Gas”, staged in 1922 in Petrograd at the Bolshoi Drama Theater (BDT), based on Georg Kaiser’s play “Gas I”. The article examines the relevance of choosing this play to stage at the BDT, the dramatic features of G. Kaiser’s play, the specifics of the scenography, and the principles of action composition, the place and role of actors in the production. The scientific novelty lies in the comprehensive consideration of the main aspects associated with the perception of a work of German Expressionism, based on the reconstruction and analysis of the performance, taking into account its elements such as directorial interpretation, literary plot, genre, scenographic solution, action composition, the actor’s mode of existence, etc. As a result, the high relevance of staging G. Kaiser’s play “Gas I” in 1922 at the BDT was determined. The features of the dramaturgy of this work and their stage embodiment were revealed. The directorial interpretation was identified. The specifics of the scenography and the principles of action composition in the performance, as well as the place and role of actors in the production, were determined.
Constructing classifications in Russian language lessons as a way to form the universal skill of 6th-grade students (using the example of studying the topic “The Adjective”)
Authors: Chausova Olga Vladimirovna
Published: February 2025

The aim of the research is to substantiate the necessity and methodology of a phased introduction of special assignments into the Russian language curriculum for 6th grade in general education institutions. These assignments are designed to develop the basic logical action of “establishing a significant feature of classification, grounds for generalization and comparison, and criteria for the analysis being carried out”. The article proposes stages for forming the ability to construct classifications of studied phenomena on the material of the subject “Russian Language”, analyzes the material of the current school textbook for compliance with the stages of instruction, and indicates the conditions for introducing assignments on the construction of classifications into practice within the framework of studying the topic “The Adjective”. The scientific novelty of the research lies in the development of a methodology for the consistent formation of the basic logical action for identifying the basis for dividing the studied grammatical phenomena into groups, classifying them on the basis of generalization and comparison, using the example of working with sixth-graders. The article describes three stages of forming a universal learning skill for constructing classifications on the material of grammar. At the first, initial stage of work, it is proposed to use tasks to identify the similarities and differences in the grammatical features of language units, to consider and compare the possibilities of variable and constant grammatical features on practical material. At the second, advanced stage, the bases for grouping the studied phenomena according to one or more features are identified, and the functioning of the studied phenomena in a similar context is considered. At the third, final stage, it is assumed that the results of the work are comprehended in order to identify generalized logical methods for constructing classifications within the framework of the studied topic. As a result, it was determined that compliance with the indicated stages of including tasks on the classification of studied phenomena will contribute to the development of basic logical actions, such as analysis, comparison, generalization, since conditions are created for the conscious assimilation of linguistic phenomena by students.

Authors: POTOLOKOVA D.B. , DOVBONOS T.A.
Published: February 2025

The article presents a review of scientific literature and a description of a clinical case of combined arterial and venous cerebrovascular pathology — cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) and venous brain angioma. CADASIL is a rare disease of the nervous system; however, it is also the most common monogenic angiopathy of the brain, leading to the early onset of acute and chronic cerebrovascular disorders. The work reflects modern views on epidemiology, etiopathogenesis, clinic, diagnosis, and management of the described pathology. Updated data on the prevalence of typical and atypical NOTCH3 gene mutations, the significance of the accumulation of pathologically altered proteins in the vascular wall for the development of selective vasoconstriction and other stages of the cascade of pathological vascular disorders, as well as the role of pericytes in the development of genetically determined vasculopathy are presented. The results of studies of correlative relationships between NOTCH3 gene mutation variants and the clinical picture of the disease, as well as analysis of genotype and phenotype features in patients with CADASIL in different regions of the world, are shown. A retrospective analysis of modern CADASIL clinical criteria was conducted, showing high sensitivity and specificity, facilitating rapid patient screening for genetic testing to confirm the diagnosis. The use of clinical criteria as a diagnostic tool is shown in the example of our own clinical observation. The evolution of therapeutic approaches and secondary prevention of cerebrovascular lesions in the presence of CADASIL is described.
U.S. exorbitant privilege: Expected vs. realized
Authors: Lewis Angus
Published: February 2025

The expected returns on the U.S. net foreign asset position (NFA) feature prominently in theories of the U.S. exorbitant privilege. However, existing empirical studies of NFA dynamics focus on measuring realized outcomes. I use simulations of the NFA to show quantitatively that inferences based purely on realized NFA dynamics are misleading. I provide new estimates based on ex-ante expected returns by combining empirical asset pricing models with micro data on U.S. assets and liabilities. I investigate the most important determinants of expected NFA returns and any sources of asymmetry between expected returns on U.S. assets and liabilities. I document that expected returns on U.S. debt foreign assets are higher than the expected returns on U.S. debt foreign liabilities. I find that the most important determinant of NFA returns over the last 25 years has been changes to the composition of U.S. liabilities which along with the growth in the gross size of U.S. liabilities have led to the U.S. now having a net negative position in equity. These findings contrast with realized NFA returns, which over the same period are dominated by return differences between U.S. and foreign equities.
Positive isotropic components of the 2025 Santorini-Amorgos earthquakes
Authors: Zahradnik Jiri , Sokos Efthimios , Roumelioti Zafeiria , Turhan Fatih
Published: February 2025

We used full waveforms of the Hellenic Unified Seismic Network (HUSN) regional stations and a frequency range of 0.03-0.06 Hz. We calculated full moment tensors (MTs) and focused on their ISO and CLVD components. In the tested depth range of 1-20 km, the medians of ISO (=VOL) and CLVD are positive, but their 68% confidence intervals are broad due to the tradeoff of the non-DC with depth. When constraining source depths to ≥ 7 km, indicated by relocations, MTs have unambiguously positive ISO and positive CLVD, pointing to a shear-opening source process.
FeynCalc applied to solve a semiclassical problem:
Authors: POMARES MARTIN
Published: February 2025

Feynman’s diagrams are a good symbolic tool for the calculation of path integrals en elementary particle physics. Therefore, currently in physics there is an interest to apply quantum mechanics to classical mechanics. It implies that is important also contribute to the development of the theory of path integrals applied to problems of classical mechanics which this is one of the first works in that approach. This kind of research works in theoretical physics is a basis to study the application of Feynman’s diagrams as a way of symbolic algebra to solve problems of classical interactions as if it were of the quantum. In that sense, the author has regarded in basic way the application of the computational tool as FeynCalc, supported by Mathematic 8.0. As a consequence, FeynCalc was used to simulate a semi classical problem with an equivalent of a quantum representation. And the only regarded aspect of representing a classical problem into the quantum approach, this research contributes to a symbolic representation of the physics, where some classical problem can be solved regarding quantum mechanism.
A robust method of assessing foosball matchups independent of tournament structure
Authors: Linden Philip
Published: February 2025

The results of randomly seeded single-elimination tournaments does not reflect a player or team's relative rank, or foosball performance score. Existing ranking such as Elo Ranking or Swiss systems depend on a large number of matches to be played to produce accurate results. We present a method of determining rank using the relative performance of a player's opponent and the points scored on that opponent during a foosball match. We demonstrate that the Hing-King-Linden Score, or HKL, is a robust method of predicting foosball matchups between two players or teams, and a reliable way to seed teams and tournaments fairly based on only the number of matches played and tracking points scored against each opponent. We show the utility of HKL using the real results of a randomly seeded single-elimination tournament.
Cognitive resilience and vulnerability to socioeconomic disadvantage: Predictors across individual, family, school, and neighborhood contexts
Authors: Shariq Deena , Romeo Rachel R , Gard Arianna M
Published: February 2025

Though much research links socioeconomic disadvantage to cognitive difficulties during adolescence, many youth demonstrate resilience. Person-centered approaches can be used to quantify this developmental heterogeneity and challenge deficit-centered frameworks. This study leverages person-centered and data-driven methods to quantify and characterize cognitive heterogeneity in a socioeconomically diverse dataset of early adolescents from the Adolescent Brain Cognitive Development℠ Study (N = 9,839; 47.7% female sex; Mage = 9.90 years; 46.7% White). Four profiles based on access to socioeconomic resources (SER) and multi-domain cognitive functioning were identified, including two profiles characterized by moderate-to-high-SER (74.5%) and two profiles characterized by low-SER (25.5%). Among youth in low-SER environments, 88.6% demonstrated cognitive performance scores similar to youth with moderate-to-high access to SER (“cognitive resilience”), whereas 11.4% demonstrated markedly lower performance relative to the other profiles (i.e., 1.3 to 2.3 SD below the sample mean; “cognitive vulnerability”). Ridge regression identified ecological factors associated with profile membership at the individual level and within family, neighborhood, and school contexts. Suburban residence (odds ratio [OR] = 1.30), advanced pubertal maturity (OR = 1.20), bilingualism (OR = 1.14), and greater caregiver monitoring (OR = 1.10) were most strongly associated with lower-SER youths’ membership in the resilient versus the vulnerable profile. Results emphasize the need to challenge deficit-centered frameworks by investigating heterogeneity within adversity-exposed youth and identifying context-specific risk and protective factors.

The N2pc is widely employed as an electrophysiological marker of an attention allocation. This interpretation was largely driven by the observation of an N2pc elicited by an isolated relevant target object, which was reported as Experiment 2 in Eimer (1996). All subsequent refined interpretations of the N2pc had to take this crucial finding into account. Despite its central role for neurocognitive attention research, there have been no direct replications and only few conceptual replications of this seminal work. Within the context of #EEGManyLabs, an international community-driven effort to replicate the most influential EEG studies ever published, the present study was selected due to its strong impact on the study of selective attention. We revisit the idea of the N2pc being an indicator of attentional selectivity by delivering a high powered direct replication of Eimer's work through analysis of 779 datasets acquired from 22 labs across 14 countries. Our results robustly replicate the N2pc to form stimuli, but a direct replication of the more influential N2pc to color stimuli technically failed. We believe that this pattern not only sheds further light on the functional significance of the N2pc as an electrophysiological marker of attentional selectivity, but also highlights a methodological problem with selecting analysis windows a priori. By contrast, the consistency of observed ERP patterns across labs and analysis pipelines is stunning and this consistency is preserved even in datasets that were rejected for (ocular) artifacts, attesting the robustness of the ERP technique and the feasibility of large-scale EEG replication studies.
Does Music Training Improve Emotion Recognition? Longitudinal and Correlational Evidence from Children
Authors: Lima Cesar
Published: February 2025

Music training is widely claimed to enhance nonmusical abilities, yet causal evidence remains inconclusive. Moreover, research tends to focus on cognitive over socioemotional outcomes. In two studies, we investigated whether music training improves emotion recognition in voices and faces among school-aged children. We also examined music-training effects on musical abilities, motor skills (fine and gross), broader socioemotional functioning, and cognitive abilities including nonverbal reasoning, executive functions, and auditory memory (short-term and working memory). Study 1 (N = 110) was a 2-year longitudinal intervention conducted in a naturalistic school setting, comparing music training to basketball training (active control) and no training (passive control). Music training improved fine-motor skills and auditory memory relative to controls, but it had no effect on emotion recognition or other cognitive and socioemotional abilities. Both music and basketball training improved gross-motor skills. Study 2 (N = 192) compared children without music training to peers attending a music school. Although music training correlated with better emotion recognition in speech prosody (tone of voice), this association disappeared after controlling for socioeconomic status, musical abilities, or short-term memory. In contrast, musical abilities correlated with emotion recognition in both prosody and faces, independently of training or other confounding variables. These findings suggest that music training enhances fine-motor skills and auditory memory, but it does not causally improve emotion recognition. Observed advantages in emotion recognition likely stem from preexisting musical abilities and other confounding factors such as socioeconomic status.

When and how do children come to understand various kinds of visual media (e.g., pictures,videos, scale models), and how does early experience contribute to variation in the developmentof these symbolic behaviors across global contexts? Researchers have investigated how childrenfrom Western convenience samples understand visual media, but less is known about how thiscomprehension varies across children in diverse global contexts. Indeed, prior work investigatingpicture comprehension suggests that children in different contexts may understand pictures atdifferent developmental timepoints, potentially due to variation in their early picture experiences.These findings demonstrate the need for more research investigating consistency or diversity inchildren’s comprehension of additional kinds of visual media across contexts. Theexperience-dependence of visual media comprehension could provide important insight intothese abilities’ origins, as well as the appropriateness of cross-cultural use of visual media inearly childhood measurement.
From Misinformation to Motivation: Why Generation Z is (or Isn’t) Choosing Teaching
Authors: Snell Rebecca Jessica Somerville , Klassen Robert M.
Published: February 2025

This study explores the career motivations and aspirations of 16–18-year-olds in the UK. Using survey data from 756 participants, we examined how this age group view career options, and how teaching compares to other available sectors. Teaching was recognised as a fun, people-focused career, but was seen not valued for its job security, instead being seen as underpaid with a lack of autonomy. Across all careers, participants demonstrated a fixed mindset when considering their skills. Gender, ethnicity, and school type influenced career perceptions and aspirations, highlighting the need for targeted career guidance to address misconceptions and improve careers awareness.
Overview of Quantitative Behavior Analysis

Despite the substantial role of extended relatives in childcare in China and worldwide, their involvement in the care of autistic children remains understudied. This quantitative study aims to characterise the role of extended relatives in caring for autistic children, and to examine the relationship between the stigma and support provided by extended relatives. Using a cross-sectional design 233 Chinese parents of autistic children were recruited by convenience and snowball sampling. The results showed that Chinese autistic children have frequent interactions with their extended relatives, with 40% living in extended family households. Extended relatives are a common source of support, and their support is considered helpful by many parents. Linear regression analysis indicated that household structure and extended relatives’ stigma towards the autistic child have a significant effect on both the frequency and helpfulness of support. Living in a nuclear or extended family household significantly moderated the effects of extended relatives’ stigma on their support. In families living apart from their extended relatives, stigma towards the autistic child and stigma towards parents were both negatively associated with the support offered by extended relatives. In contrast, when living with extended relatives, stigma towards the parent was positively associated with support, while stigma towards the autistic child was unrelated to the support provided. Our findings highlight the important role of extended relatives in the care for autistic children. Caregiver interventions should consider including extended relatives in the programme focus to address stigma and strengthen family support.
Agents generalize to novel levels of abstraction by using adaptive linguistic strategies
Authors: Kobrock Kristina , Ohmer Xenia , Bruni Elia , Gotzner Nicole
Published: February 2025

We study abstraction in an emergent communication paradigm. In emergent communication, two artificial neural network agents develop a language while solving a communicative task. In this study, the agents play a concept-level reference game. This means that the speaker agent has to describe a concept to a listener agent, who has to pick the correct target objects that satisfy the concept. Concepts consist of multiple objects and can be either more specific, i.e. the target objects share many attributes, or more generic, i.e. the target objects share fewer attributes. We test two directions of zero-shot generalization to novel levels of abstraction: When generalizing from more generic to very specific concepts, agents utilize a compositional strategy. When generalizing from more specific to very generic concepts, agents utilize a more flexible linguistic strategy that involves reusing many messages from training. Our results provide evidence that neural network agents can learn robust concepts based on which they can generalize using adaptive linguistic strategies. We discuss how this research provides new hypotheses on abstraction and informs linguistic theories on efficient communication.

IAPS are already a huge worldwide environmental issue, endangering biodiversity, altering ecosystems, and disrupting socioeconomic systems. The current study aimed to assess the distribution, diversity, and effect of IAPS in the Indo-Nepal buffer zones of Kanchanpur District, Nepal, with a focus on Bhimdatta and Dodharachadani Municipality. Between September 2023 and July 2024, a comprehensive field survey was undertaken at the research sites. Using quadrat sampling and herbarium identification, 21 plant species were identified. These species belonged to 11 families of which Asteraceae family was dominant in all study sites; holding 8 species. On the basis of IVI, 10 invasive plant species were recorded as dominant in all study sites. Of these, the highest importance value index of dominant invasive alien plant species at site 1 was recorded by Partheniun hysterophorus (41.39) and lowest by Mimosa pudica (2), whereas among dominant invasive alien plant species of site 2 the highest IVI was of Lantana camara (56.46) and lowest by Argemone maxicana (3.82). At site 3, the highest importance value index of dominant invasive alien plant species was recorded by Parthenium hysterophorus (28.35) and lowest by Bidens pilosa (2.85). The study's findings could have ecological and economic implications, such as loss of biodiversity, soil degradation, and health dangers. Furthermore, the study revealed the adaptive reproductive tactics of IAPS, such as allelopathy and seed viability, which increase their invasive nature. The findings highlight the critical need for focused management techniques to minimize the growing threat of IAPS, particularly in buffer zones where conservation efforts are currently underexplored.
Analysis of Metaheuristic Solutions to the Response Time Variability Problem
Authors: Joshi Rajendra Prasad
Published: February 2025

The problem of variation in the response time is known as response time variability problem (RTVP). It is combinatorial NP-hard problem which has a broad range of real-life applications. The RTVP arises whenever events, jobs, clients or products need to be sequenced so as to minimize the variability of the time they wait for their next turn in obtaining the resources they need to advance. In RTVP the concern is to find out near optimal sequence of jobs with objective of minimizing the response time variability. The metaheuristic approaches to solve the RTVP are: Multi-start (MS), Greedy Randomized Adaptive Search Procedure (GRASP) and Particle Swarm Optimization (PSO). In this paper, the computational result of MS and GRASP will be analyzed.
