Nghiên cứu này nhằm tìm hiểu nhận thức, khả năng tiếp cận và sử dụng thương mại điện tử, cũng như chỉ ra những rào cản trong việc ứng dụng thương mại điện tử trong sản xuất nông nghiệp của nông hộ. Nghiên cứu được thực hiện thông qua phỏng vấn bán cấu trúc với 60 nông hộ, 3 người am hiểu và thu thập thông tin thứ cấp liên quan. Kết quả nghiên cứu cho thấy phần lớn nông hộ đã biết về thương mại điện tử, đã tiếp cận và sử dụng các kênh thương mại điện tử khác nhau. Facebook và Zalo là hai kênh được nông hộ sử dụng nhiều nhất cho việc giải trí, liên lạc và mua bán trực tuyến. Trong đó, facebook được nông hộ sử dụng để mua các yếu tố đầu vào và bán các sản phẩm từ trồng trọt. Tuy nhiên, tâm lý lo sợ rủi ro, thiếu hiểu biết và kỹ năng sử dụng cùng với thói quen mua bán hàng hoá trực tiếp đang là các rào cản chính trong việc ứng dụng thương mại điện tử của nông hộ.
Unveiling the Overlooked Negative Effects that are Spawned by Cognitive Ability on L2 Learning: Bridging the Research Gap
Authors: Li Yingyang , Liang Jinming , Zhao Zirui , Li Kexin
Published: July 2024

Although cognitive ability is essential to second language acquisition (SLA), there can be major obstacles associated with it. This study looks into how cognitive ability affects Chinese adults preparing for the IELTS exam by having them learn English. We discovered via a number of experiments (62 Chinese students took part in) that adult learners frequently rely on well-known language systems, which can result in inefficiency and lower-quality language output. These results point to a possible detrimental relationship between cognitive ability and SLA, especially in adults who have passed the critical age. By examining these effects from linguistic, neurological, and psychological angles, the study provides insights into the ways in which cognitive factors can facilitate or impede language acquisition.

The theory of new institutional economics provides a powerful tool for analyzing the transformation and innovation of China's discipline inspection and supervision system. Changes in the discipline inspection and supervision system include induced and coercive transformations, with changes in interest patterns and power relationships having a significant impact on institutional change. Path dependence and institutional breakthrough mechanisms jointly influence the process of institutional change. Based on this, the paper also discusses the policy background and motivations for the innovation of the discipline inspection and supervision system, and proposes directions for institutional innovation, including strengthening the leadership of the Party, diversifying supervision, and expanding cooperation.
Adsorption of Malachite Green Dye in Aqueous Solution Using Low-Cost Synthesis of Zinc Oxide Urea Formaldehyde Nanocomposite as Adsorbent
Authors: Warbhe Prapti P.
Published: July 2024

Abstract: In recent decades, the world’s fast industrialization has made water contamination the most serious problem in the world. Organic dyes, especially malachite green, are synthetic dyes used in the textile industries to dye silk, cotton, leather, wool, paper, etc. and consequently discharged into the water resources that pollute aquatic environments. The purpose of the research work is to study the efficiency of zinc oxide urea formaldehyde nanocomposite used as an adsorbent in the removal of malachite green dye from polluted wastewater. The main stages of this work include the synthesis of zinc oxide by the simple sol-gel method at room temperature. The synthesised nanoparticle was coated with urea formaldehyde to increase its efficiency. The characterization techniques such as XRD, FTIR, SEM, and BET of the synthesised nanomaterials show that the zinc oxide urea formaldehyde nanocomposite was successfully synthesised. The batch adsorption study of the dye onto the ZnO-UF nanocomposite was investigated with a UV-visible spectrophotometer. The application of this synthesised nanocomposites as an adsorbent successfully adsorbed more than 97% malachite green dye at a reducing dye strength of 40 PPM, doses of 0.35 g, and pH 8 within a 90-min equilibration time.
Measures of Economic Disadvantage Explain Outcomes Differently Across Geographies
Authors: Clausen Robin
Published: July 2024

Alternative poverty measures have been proposed in response to the emerging insufficiencies of the National School Lunch Program (NSLP) eligibility data. The analysis presented here involves seven poverty measures. Using outcome measures as a yardstick, we can assess how poverty measures explain these outcomes and note variations between geographical locales (assessing predictive validity). An analysis of 2019 data from Montana revealed that no poverty measure emerges as consistently meeting or exceeding the results found with the NSLP on the state level. Results are mixed based on locale (size) and distance from an urban centre, and within school communities.

Published: July 2024

This paper seeks to see the integrative points of the struggle for Islamic teachings and sosial piety that need to be taught to early childhood based on children's Arabic fairy tales. This study uses two approaches, namely an educational approach and an Islamic approach. The educational approach studied is the application of the Sosial Learning Theory proposed by Albert Bandura in analyzing any binary opposition of good and bad attitudes in each quotation (dialogue or story) of the children's fairy tales studied. The Islamic approach studied is to use the Quranic perspective as a source of human life guidance which is applied to Islamization of the results of Sosial Learning analysis so that good and bad attitudes can be assessed as an important dogmatic reminder instrument in fostering the character of sosial piety and Islamic personality. The use of two approaches as characteristics of interdisciplinary studies in this study leads to primary sources that refer to a children's fairy tale entitled al-Najm al-Kabīr by Dr. Zahīrah al-Bailī. This research concludes that the dogma-lessons of sharing love and affection in early childhood that can be done by loving each other and habituating apologizing if you make mistakes will reflect-stimulate personality in shaping the character of devotion to parents and sosial relationships.

This research examines the problems that often occur in the world of education. The level of criminalization of PAI teachers is very frequent lately. The lack of a firm attitude from the government makes this problem often occur in various regions. It is the duty of the government to minimize the occurrence of criminal acts against teachers. Efforts that can be made at this time are the need for affirmation related to government regulations by developing policies related to legal protection for the teaching profession and disseminating information to the entire community regarding these policies. Becoming a profession as a teacher is a very noble job, which is naturally given a protection or legal umbrella in carrying out his profession as a teacher. The government makes a policy to provide legal protection for a teacher in carrying out his duties as an educator. This is stated in Article 39 of Law Number 14 of 2005 which states that education units are obliged to provide protection to teachers when carrying out their duties. Then the second paragraph of article 39 includes legal protection, professional protection, protection of occupational safety and health. In addition, PAI teachers are also entitled to a legal umbrella in carrying out their duties and responsibilities as well as intellectual rights as stated in Article 14 of this Law. Legal protection for a PAI teacher in carrying out his profession includes acts of violence, then threats, discriminatory treatment, intimidation, or unfair treatment on the part of students, parents of students, and the community.

Product Placement in Films: A Comparative Study of American and Chinese Consumers’ Attitudes
Authors: Zhou Yi ,   University of Leicester, United Kingdom
Published: July 2024

This study delves into the differing attitudes of Chinese and American students regarding product placement (PPL) in major motion films. It employs a theoretical framework comprising three key aspects of PPL: its historical evolution, brand integration, and past perceptions. The research employs two primary research methods, questionnaires and focus group interviews, in order to gather insights and opinions from consumers on their views and attitudes toward PPL. Drawing upon the findings from the questionnaires and insights obtained through interviews with Chinese and American consumers, it reveals two distinct sets of attitudes: Chinese participants predominantly express strong reservations about PPL, while a majority of American respondents present diverse arguments in support of its efficacy in the American media ecology in general and in films in particular. While data collection for this study was undertaken already in 2015, this data is nevertheless worth analyzing, both for historic reasons as well as for revealing continuing differing trends in different cultures regarding their media awareness.

Published: July 2024

Despite its importance, childhood trauma is often not recognized as ?
pathogenic fact that affects the (de)formation of personality and influences
the development of various psychological difficulties and bad habits,
including the likelihood of future psychoactive substance abuse. This study
aimed to examine the relationship between adverse childhood experiences and
substance misuse in adolescence. The research was conducted on a sample of
380 secondary school students (aged 14 to 19 years) from Vojvodina. The
questionnaires used included: the Questionnaire of Sociodemographic
Characteristics and Psychoactive Substance Uses, which was designed for the
purpose of this research, and the Childhood Trauma Questionnaire (CTQ,
Bernstein & Fink, 1998). The research employed the methods of descriptive
statistics, Spearman?s correlation coefficient, and the chi-squared test. A
total of 10.2% of respondents used psychoactive substances less than once a
week, 3.2% used psychoactive substances once a week, and 1.8% used
psychoactive substances every day. In terms of traumatic experiences, only
6.6% of respondents reported having no or minimal trauma, the majority
(62.9%) had a low-to-moderate level of traumatization, while nearly one in
three respondents (30.5%) exhibited a moderate-to-severe or
severe-to-extreme level of traumatization. A significant correlation was
found between the intensity of each form of traumatization and the frequency
of psychoactive substance use, with the correlations being most pronounced
for emotional abuse (r = .38), sexual abuse (r = .35), and total
traumatization (r = .34). The results highlight the importance of preventing
drug abuse in the student population, as well as the need to sensitize and
educate teachers and school counselors to ensure the timely recognition of
traumatization in adolescents, and help prevent or mitigate psychoactive
substance use problems and other mental health issues.
Mathematical Modelling of Catastrophic Surge and Seiche Events in the Azov Sea Using Remote Sensing Data
Authors: Protsenko E. A. , Panasenko N. D. , Protsenko S. V.
Published: July 2024

Introduction. This work is devoted to the mathematical modelling of extreme sea level fluctuations in the Azov Sea using remote sensing data. The aim of the study is to develop and apply a mathematical model that allows more accurate prediction of surge and seiche events caused by extreme wind conditions. The relevance of the work is due to the need to improve the forecasts of hydrodynamic processes in shallow water bodies (such as the Azov Sea), where such phenomena can have significant economic and ecological consequences. The goal of this work is to develop and apply a mathematical model for predicting extreme sea level fluctuations in the Azov Sea caused by wind conditions.Materials and Methods. The study is based on the analysis of remote sensing data and observations of wind speed and direction over the Azov Sea. The primary method used is mathematical modelling, which includes solving the system of shallow water hydrodynamics equations. Wind condition data were collected from November 20 to 25, 2019, during which catastrophic sea level fluctuations were observed. The model considers the components of water flow velocity, water density, hydrodynamic pressure, gravitational acceleration, and turbulence exchange coefficients.Results. The modelling showed that prolonged easterly winds with speeds up to 22 m/s led to significant surge and seiche fluctuations in sea level. The maximum amplitudes of fluctuations were recorded in the central part of the Taganrog Bay, where the wind direction and speed remained almost constant throughout the observation period. Data from various platforms located in different parts of the Azov Sea confirmed a significant decrease in water level in the northeast and an increase in the southwest.Discussion and Conclusions. The study results confirm that using mathematical models in combination with remote sensing data allows more accurate predictions of extreme sea level fluctuations. This is important for developing measures to prevent and mitigate the consequences of surge and seiche events in coastal areas. In the future, it is necessary to improve models by including additional factors such as climate change and anthropogenic impact on the Azov Sea ecosystem.
An Adaptive Mesh Refinement Solver for Regularized Shallow Water Equations

Published: July 2024

Introduction. We present a novel adaptive mesh refinement (AMR) solver, SWqgdAMR, based on the open software platform AMReX. The new solver is grounded in regularized shallow water equations. This paper details the equations, their discretization, and implementation features within AMReX. The efficacy of SWqgdAMR is demonstrated through two test cases: a two-dimensional circular dam break (collapse of a liquid column) and the collapse of two liquid columns of different heights.Materials and Methods. The SWqgdAMR solver is developed to extend the applicability of regularized equations in problems requiring high computational power and adaptive grids. SWqgdAMR is the first solver based on the quasigas dynamic (QGD) algorithm within the AMReX framework. The implementation and validation of SWqgdAMR represent a crucial step towards the further expansion of the QGD software suite.Results. The AMReX-based shallow water equations solver SWqgdAMR with adaptive mesh refinement is described and tested in detail. Validation of SWqgdAMR involved two-dimensional problems: the breach of a cylindrical dam and the breach of two cylindrical dams of different heights. The presented solver demonstrated high efficiency, with the use of adaptive mesh refinement technology accelerating the computation by 56 times compared to a stationary grid calculation.Discussion and Conclusions. The algorithm can be expanded to include bathymetry, external forces (wind force, bottom friction, Coriolis forces), and the mobility of the shoreline during wetting and drying phases, as has been done in individual codes for regularized shallow water equations (RSWE). The current implementation of the QGD algorithm did not test the potential for parallel computing on graphical cores.
ESO-based slip film control of the cotton picking head hydraulic system
Authors: Liu Q. , Klim M. , Duam B. , Chen R.
Published: July 2024

A slip film control technique based on an expansion state observer is proposed to address issues such as unclear internal characteristics of cotton-picking hydraulic equipment, modeling difficulties owing to external random disturbances, poor output speed stability, and limited controllability. First, a third-order mathematical model of the valve-controlled motor is established. Then the unmodeled model's dynamic errors and load disturbances are uniformly integrated in-to the 'total disturbances' for real-time estimation and compensated to the sliding-mode controller combined with the expanded state observer by the second-order expanded state observer, and finally, a complete valve-controlled motor system is constructed in the 'MATLAB/Simulink-AMESim' simula. The simulation test results show that the control algorithm is faster, more stable, and more resistant to interference than the PID controller and the backstepping sliding mode controller, with control accuracy improved by 94.5% and 85.6%, respectively, and hydraulic motor output with a constant rotational speed is achieved.

The freeze-up those forms on rivers in the autumn-winter period significantly impacts on the hydrological, hydrochemical, biological processes of rivers, as well as the work of hydropower, shipping, fisheries, etc. In modern conditions, the formation, duration, and break-up of freeze-up on rivers occurs under the influence of natural, anthropogenic factors and climatic changes. Therefore, the research of modern trends of the freeze-up duration on the river and the determination of its calculation characteristics is an urgent task. Traditionally, the multi-annual mean, minimum and maximum values of the freeze-up duration on rivers are determined. Such indicators are important, but they still provide a rather limited knowledge about the freeze-up over a period of time. Expand knowledge about the variability, magnitudes, duration, dates of appearance freeze-up and break-up can by determining its probabilistic characteristics, but such research have not been carried out for the rivers of Ukraine, including for the rivers of the Prypiat basin.
The objective of this paper is to determine the probabilistic characteristics of the freeze-up duration of the rivers of the Prypiat basin within Ukraine, as well as the analysis of the obtained results.
The data of 29 water gauges were used for the period from the beginning of observations to 2020, inclusive. As statistical parameters of the analytical distribution of the freeze-up duration, the multi-annual mean value, the coefficient of variation and the coefficient of asymmetry were used. The Pearson distribution of type III was used to created analytical curves of the freeze-up duration, and the Weibull formula was used for the empirical distribution of the freeze-up duration.
In this paper, the probabilistic characteristics and statistical parameters of the freeze-up duration on the rivers of the Prypiat basin within Ukraine are determined. The probability distribution of Pearson type III quite satisfactorily describes the empirical points of the freeze-up duration on the rivers of the Prypiat basin within Ukraine. The vast majority of the analytical curves of the distribution of the freeze-up duration have a negative asymmetry. Only 8 the analytical curves have a positive asymmetry. In the Prypiat Basin within Ukraine the multi-annual mean of the freeze-up duration is 69 days and ranges from 26 to 95 days. The values of the asymmetry coefficients are small and vary from 0.01 to 1.02 for positive values and from -0.03 to -0.60 for negative values. The coefficients of variation change within small limits from 0.34 to 0.79.
Probabilistic characteristics can use for the design and operation of any hydrotechnical structures, as well as the work of economic sectors that are related to the use the rivers. In addition, the research results can be used for further research, namely any search for prognostic dependencies, generalizations, zoning, etc.

Anthropogenic impact on the biosphere has become one of the major factors dictating the conditions of our existence on the Earth. The study was aimed to perform comparative analysis of the rate of cytogenetic alterations, indicators of proliferation and destruction of the nucleus in the vaginal epithelium reflecting the reproductive health status of pregnant women aged 26–33 years living in conditions of radioactive, chemical and combined contamination of the territories of Bryansk Region. Cytogenetic status of 80 pregnant women divided into four groups, 20 individuals per group, was assessed using the micronucleus test. The rate of cytogenetic alterations, indicators of proliferation and destruction of the nucleus in the vaginal epithelium of pregnant women living in the environmentally disadvantaged territories was 1.9–4.9 times higher (p < 0.001) compared to that in women living in the environmentally safe (control) districts. The combined effects of radioactive and chemical contamination resulted in the significantly higher rate (increase from 12.8 to 81.4%) of cells with micronuclei, nuclear protrusions, binucleated cells, as well as cells with karyopyknosis and karyolysis compared to the effect of only one pollution factor. The findings are likely to show synergy of the effects of radiation and chemical factors on the cytogenetic status of pregnant women.

Physical development in adolescence is one of the key aspects of the modern society’s well-being. Assessment of physical development in children and adolescents represents an essential component of the pediatric population health status estimation being a clear indicator of the impact of lifestyle, environment, and learningmprocess on the child’s body. The study was aimed to assess the dynamic changes of physical development indicators in the high school-age children in the Samara Region over a decade. The paper deals with the anthropometric data of physical development acquired in 2013 and 2023. A total of 476 children aged 14–16 years were examined (256 boys, 220 girls). Physical development assessment performed in the group of high school-age boys revealed significant changes. Boys of all ages examined in 2023 lagged behind their peers examined in 2013 in the number of individuals with harmonious physical development. Furthermore, a significantly greater number of children with disharmonious physical development due to excess body weight were revealed in 2023. The results yielded by assessing physical development in girls are slightly different: the today’s 14-year-old schoolgirls lag behind girls examined in 2013 in the size of population with harmonious physical development. The body height comparative analysis results have shown that the today’s schoolchildren do not lag behind their peers examined in 2013 in all gender-age groups (p > 0.05). A significant increase in the schoolchildrens’ body weight relative to 2013 is likely to result from the quarantine measures related to the COVID-19 pandemic, which made children stay at home for longer and reduced their physical activity.
