Authors: Li Yan , Zheng Atai
Published: July 2024

In the context of energy saving and emission reduction to protect the environment has become a social consensus, environmental benefit is a social responsibility that enterprises must actively undertake, and the technological advantages of information technology companies make them more equipped to enhance environmental benefits. Therefore, this paper proposes countermeasures for information technology companies to enhance their social responsibility and environmental benefits. To achieve practical countermeasures for energy savings and emission reduction, this paper proposes a method to improve the LSTM power prediction model using the Sparrow search algorithm for the company’s electricity management. The model optimizes the network structure of traditional LSTM by searching for parameters such as learning rate, iteration number, and the number of neurons in the two hidden layers of LSTM through the sparrow fitness function. The model proposed in this paper has an average prediction error rate of 3.32% in predicting the annual electricity consumption of a county for five years from 2018 to 2022. After an enterprise introduced the social responsibility practice countermeasures proposed in this paper, the company’s net profit margin increased by 12.2% on average, CO2 emission reduction was 963.2 tons, the average monthly electricity consumption was reduced by 24936.5 kWh, and the environmental performance score increased from 3.2 to 5.4.

Authors: Long Yanting , Liu Ping
Published: July 2024

This paper proposes a reform of the teaching methodology based on the exercise prescription course centered on intelligent exercise prescription recommendation and designs a specific implementation plan. A criterion function is used to determine and represent the constant terms of the user-set data using the K-means clustering algorithm. The personal data of users is added on this basis, and the attribute weighting is used to calculate user similarity and construct the user matrix. The core parameters of intelligentized exercise prescription are examined, and the relevant data of the exerciser group is obtained through modeling. The set of similar cases is determined, and the exercise effects in the set of similar cases are fused and calculated, and the effect level of the fused effects in the cases is discriminated. The model developed in this paper is implemented in the college physical education classroom, and the student’s attitudes toward physical exercise and fitness levels are analyzed. The results show that the attitude towards physical exercise behavior of students in group A is significantly better than that of those in group B. The significance test (F = 7.985, Sig = 0.005) is less than 0.05. Taking the 50-meter sprint as an example, the difference in the duration between male students and female students in groups A and B is 0.83s and 0.9s, respectively, which is a large enhancement, which shows that the intelligent exercise prescription has a positive impact on physical education teaching.

Authors: Jiang Chaofan
Published: July 2024

One of the important directions for the reform of ideology and politics is the integration of big data with ideological and political education. As a type of big data technology, knowledge graphs can display a clear knowledge architecture, thereby optimizing the educational impact of courses in ideology and politics. In this paper, we first enhance the CRF model for processing sequence annotation, which is based on BiLSTM. We then propose features for judging entity relationships. Next, we use the classification model to classify the relationships within it. Finally, we integrate and store the knowledge of both civics and political science to create a comprehensive civics and political science knowledge graph. We found that the experimental class, applying knowledge mapping for Civics education, increased its total Civics score by 5.88 points and outperformed the control group in the knowledge memorization and application tests by 6.33 and 3.54 points, respectively. The experimental class’s post-test score for deep teaching interest reached 22.38, surpassing the control group’s evaluation, and the surface orientation decreased by 1.91 points. Research has demonstrated the benefits of using knowledge mapping in teaching to enhance students’ civics performance and learning interest.

Published: July 2024

Due to the complexity and tediousness of the current audit process, the development of audit intelligence has become a general trend. In order to improve the audit quality, the study establishes an intelligent financial audit model based on audit opinion for the supply chain finance business of state-owned enterprises after analyzing the application of the audit function of deep learning, for which an audit prediction model based on the Gray Wolf Optimization Algorithm (GWO-Optimization) and the fusion of Long and Short Term Memory Network (LSTMN) is proposed. The supplier of a state-owned enterprise is selected as the research object, and the GWO-LSTM model is trained and tested by constructing the audit opinion prediction index system and data collection, comparing it with the BP neural network and support vector machine model, and combining it with the gray prediction model for predicting the audit opinion of the samples, in order to improve the model’s practical application ability. The GWO-LSTM model performs better in predicting audit opinions than the comparison models, as evidenced by the results. Its prediction and training accuracies are above 80%, and the accuracies of RMSE, MAE, and R² are finally stabilized at 0.1, 0.1, and 0.948, and the combined accuracy of prediction in practical application reaches 90%. The model in this paper can scientifically predict the audit opinion, thus improving the efficiency of the audit data analysis for the supply chain finance business of state-owned enterprises.

Authors: Xie Xiaoni
Published: July 2024

Under the era of intelligence and informational technology, society has set higher requirements for the cultivation of talents in colleges and universities. This paper builds up a school-enterprise cooperation training model on the cultivation demand of applied talents in finance and taxation, and the employment quality data after the application of the model is statistically analyzed with the data of H universities in Guangdong Province. At the same time, after constructing the evaluation index system of the quality of the training of applied talents in finance and taxation under the model of school-enterprise cooperation by using the hierarchical analysis method and assigning weights to it, the quality of the training of the talents is comprehensively evaluated by the fuzzy comprehensive evaluation method. It was found that the employment rate of H college increased from 74.17% to 97.59% in the past ten years, and the counterpart rate increased from 73.54% to 89.24% in 2014. The study shows that A10 Employer Enterprise Satisfaction, A2 Enterprise Cooperation Platform, and A6 Enterprise Mentor Guidance have the highest scores of 86.215, 84.296, and 84.137, respectively, indicating that enterprises play an important and positive role. The A3 curriculum and A9 employment quality scores are below 80, which suggests that there are still problems to be resolved in both the course and employment quality. This paper provides useful exploration to address the problem of inadequate and misplaced school-enterprise integration and to ensure a comprehensive improvement in the quality of training talent in finance and taxation.

Published: July 2024

Red culture is an excellent cultural achievement formed by the Chinese leading people in long-term revolutionary practice, and it has become an indispensable content of ideological and political education in colleges and universities with its high value and rich connotation. Based on the strategic positioning of red cultural resources in the curriculum system of ideological and political education in colleges and universities, this paper designs the teaching path of red cultural, ideological, and political courses and implements it. It also constructs an assessment system to evaluate the quality of teaching in red culture and civic politics and proposes the use of the particle swarm algorithm to optimize the index assignment method in hierarchical analyses. Then, the fuzzy comprehensive assessment method is used to assess the teaching approach’s implementation effect. The implementation of the teaching path resulted in medium-high assessment scores for the teaching content, teaching method, and teaching effect, indicating the effectiveness of the red culture and civics teaching path. Students’ learning attitudes were significantly improved (3.5 points) compared with those before teaching (2.26 points), and it was found that the scores on the ideological and political quality test of the students who were taught with the integration of red resources were significantly higher than those of the traditional classes (P<0.05). This paper is critical for integrating cultural resources from the red minority into ideological and political education in colleges and universities.

Published: July 2024

In this paper we conducted a study referring to survey of background magnetic field in a laboratory of Electrical Engineering Faculty, where students carry out didactic activity. Based on three sets of measurements made in the 2017-2023 period, a characterization of the main field sources and the background magnetic field was performed. During this period, the power supply network has suffered some changes, and in terms of the used instruments, it was switched from spot measurement performed with commercial instruments to continuous long-term surveys performed with automatic survey systems made and calibrated by authors. In addition to considering the spatial variation of the magnetic field, the study determines and analyzes the temporal variations of the background magnetic field, namely the daily, weekly and monthly variability. Thus, a great temporal variability of the magnetic field was identified with the week days and even months, can be reached in the ratios between the magnetic field averages on the week days and on the months of the year of order 4/1 or even 5/1.

Выполнены расчеты теоретических и экспериментальных кривых кажущегося сопротивления метода электроразведки, основанного на использовании техногенного импульсного поля электрической железной дороги. Выяснено, что экспериментальные кривые этого параметра, построенные по одним и тем же исходным материалам, но при разных соотношениях погонных сопротивлений рельсов и погонных сопротивлений перехода рельс земля, так же, как и теоретические, отличаются друг от друга, практически везде, только по уровню. Сделан вывод, что неравномерность заземления рельсов не является препятствием для количественной интерпретации рассматриваемых кривых.

The theoretical and experimental curves of the apparent resistivity of the electrical exploration method based on use of anthropogenic impulse fi eld of an electric railway are calculated. It is found that the experimental curves of this parameter, built on the same source materials, but with different ratios of linear rail resistivity and linear resistivity of the rail ground transition, as well as theoretical, differ from each other almost everywhere only in level. It is concluded that uneven grounding of rails is not an obstacle to quantitative interpretation of the curves.
GEOELECTRICAL MONITORING OF THE YELCHEVSK SOIL DAM BY METHOD OF FREQUENCY DISPERSION OF ELECTRICAL RESISTIVITY
Authors: Фёдорова О.И.
Published: July 2024

В восточной части Ельчевской плотины пруда-отстойника в течение трех лет проводился геоэлектрический мониторинг с изучением частотной дисперсии электрического сопротивления на­сыпных грунтов плотины и горных пород в ее основании. Измерения выполнялись по методике вер­тикальных электрических зондирований на ряде частот с определением кажущегося электрического сопротивления на каждой частоте. Обнаружена аномалия частотной дисперсии в местах утечек воды в основании плотины и в зонах контактов пористых осадочных пород. Значения коэффициента частот­ной дисперсии зависят от гидрологических условий и уровня воды в водоеме, а также от возможно­го распространения по трещиноватым породам твердых химических веществ, содержащихся в илах отстойника.

In the eastern part of the Elchevka dam of the settling pond, geoelectric monitoring was carried out for three years with the study of frequency dispersion of electrical resistance of the bulk soil of the dam and rocks at its base. The measurements were carried out according to the method of vertical electric sounding at a number of frequencies with the determination of the apparent electrical resistance at each frequency. An anomaly of frequency dispersion was detected at the places of water leaks at the base of the dam and in the contact zones of porous sedimentary rocks. The values of frequency dispersion coefficient depend on the hydrological conditions and the water level in the reservoir, as well as on possible distribution of solid chemicals contained in the sludge of the settler over the fractured rocks.

В работе рассматриваются некоторые отдельные аспекты методики зондирования земной коры и алгоритмов обработки данных, получаемых с помощью нового электроразведочного измерительного комплекса с шумоподобными зондирующими сигналами, разработанного в НС РАН. Достоверность и точность электрических характеристик земной коры, получаемых с помощью этого комплекса, определяются точностью и стабильностью амплитуды зондирующих импульсов тока, подаваемых в индукционную зондирующую рамку при проведении измерительных сеансов. Разработан и экспериментально опробован способ повышения точности измерений, проводимых с помощью этого комплекса без применения специальных, мощных, прецизионных стабилизаторов тока (напряжения). Регистрация напряжения на зажимах силовой аккумуляторной батареи, используемой в качестве источника зондирующих сигналов, и учет этого напряжения при обработке данных зондирования обеспечивают необходимую точность измерения электрических параметров и характеристик земной коры.

The article discusses some individual aspects of methods of sounding the Earth’s crust and algorithms for processing data obtained using a new electrical measuring complex with pseudonoise probing signals developed at the RS RAS. The reliability and accuracy of the electrical characteristics of the Earth’s crust obtained using this complex are determined by the accuracy and stability of the amplitude of the probing current pulses supplied to the induction probing frame during measurement sessions. A method has been developed and experimentally tested to improve the accuracy of measurements carried out using this complex, without the use of special, powerful, precision current (voltage) stabilizers. Recording the voltage at the terminals of the power battery used as a source of probing signals and taking this voltage into account when processing the probing data ensures the necessary accuracy of measuring the electrical parameters and characteristics of the Earth’s crust.

Strength of London dispersion forces in organic structure directing agent – zeolite assemblies
Authors: Ata Karima , Mineva Tzonka , Alonso Bruno
Published: July 2024

Herein, we study the London dispersion forces between organic structure directing agents (OSDAs) and silica zeolite frameworks (FWs) among the ensemble of possible intermolecular interactions. We consider tetraalkyl-ammonium or -phosphonium OSDAs that are fully templating different silica FWs. Starting with calculations using density functional theory with dispersion correction (DFT-D3), we demonstrate that the interaction energy for dispersion forces between the OSDA and the silica FW is strictly correlated to the number of H atoms in the OSDA, irrespective of the specific structures of OSDAs or FWs. We also show that this correlation is independent of variations in formal charges and thermal motions. All calculations considered – DFT-D3 and ab-initio molecular dynamics with Born-Oppenheimer molecular dynamics (BOMD) scheme undertaken by us, and molecular mechanics (MM) from an accessible database (OSDB) – lead to the same trend. We estimate the energy of these dispersion forces to be ca. -2 kcal.mol-1 per H for efficient H-O contacts. This value is twice the energy of dispersion forces between n-alkane molecules, obtained using the same level of calculations. Such a deviation that might be explained by differences in electron polarizabilities highlights the great attraction existing between alkyl groups and siloxane bonds forming OSDA-zeolite host-guest assemblies.

Authors: Gäßler Max , Güttel Robert , Friedland Jens
Published: July 2024

The understanding of deactivation processes in heterogeneous catalysis is key for the development of new materials and exploration of new operation windows. In this contribution, the periodic transient kinetic method (PTK) is used to identify and separate catalyst deactivation processes for the first time. The PTK-method is applied for a standard Ni/Al2O3 catalyst in CO and CO2 methanation for 24 h, and compared to steady-state experiments. For the example reactions, the study exhibits different deactivation behaviour for CO and CO2 methanation. The results show that the PTK method delivers an insight into the deactivation process and furthermore gives evidence for the underlying mechanism.

Authors: Gu Zhenhua , Yang Han , Sun Xiaojie , Chen Zhen , Jiang Chenming , Duan Longhui
Published: July 2024

Bipyridines represent a class of ligands renowned for their versatility and efficacy in numerous transition metal-catalyzed reactions. Chiral bipyridine ligands are noted for their distinctive reactivity and stereoselectivity. In this work, we have designed and synthesized a class of bipyridine ligands endowed with an axially chiral scaffold. These ligands feature: (a) a precisely aligned coplanar bipyridine framework that is beneficial for metal chelation; (b) a spacious environment around the metal-bipyridine complexes, capable of hosting substrates with substantial steric bulk; (c) a chiral pocket induced by the axially chiral architecture. These atropochiral planar bipyridine ligands were successfully applied in copper-catalyzed ring-opening reactions of cyclic diaryliodoniums with bulky secondary amines, achieving high efficiency and stereoselectivity that were unsuccessful in our previous efforts.

The valorization of CO2, the most abundant waste product of human activities, has become a priority for modern society. This study explores the innovative use of sodium bicarbonate (NaHCO3) as a solid source of CO2 for carboxylation reactions performed under mechanochemical conditions. We demonstrate that NaHCO3 can be effectively used to produce high-value chemicals such as cyclic carbamates and carbonates via ball milling with propargylamines and epoxides. This approach not only avoids the handling of gaseous CO2 and high-pressure cylinders but also highlights the potential of NaHCO3 in synthesizing pharmaceutically active molecules without the massive use of solvents. Our findings suggest that the use of NaHCO3 as a solid CO2 surrogate could significantly contribute to reducing greenhouse gases and enhancing the valorization of CO2 in industrial applications.

Folate is a vitamin required for cell growth and is present in fortified foods in the form of folic acid to prevent congenital abnormalities. The impact of low-folate status on life-long health is poorly understood. We found that limiting folate levels with the folate antagonist methotrexate increased the lifespan of yeast and worms. We then restricted folate intake in aged mice and measured various health metrics, metabolites, and gene expression signatures. Limiting folate intake decreased anabolic biosynthetic processes in mice and enhanced metabolic plasticity. Despite reduced serum folate levels in mice with limited folic acid intake, these animals maintained their weight and adiposity late in life, and we did not observe adverse health outcomes. These results argue that the effectiveness of folate dietary interventions may vary depending on an individual’s age and sex. A higher folate intake is advantageous during the early stages of life to support cell divisions needed for proper development. However, a lower folate intake later in life may result in healthier aging.

Food Safety Knowledge Among Tourism Faculty Undergraduates in Slovenia: Can Social Media Leverage Educational Gaps?
Authors: Kukanja Marko , Planinc Saša
Published: July 2024

Education on food safety is vital, especially for future tourism managers undergoing training at universities. This study aims to assess the food safety knowledge of student seniors in the two Slovenian public tourism faculties, compare it with previous European and Southeast European studies, and explore the impact of social media use on food safety knowledge among tourism students. The research method utilised a questionnaire-based approach that surveyed three academic years of students until 2023/2024 from the two Slovenian public tourism faculties. Data analysis involved descriptive and bivariate statistics. The research reveals a notable scarcity of studies investigating students’ food safety knowledge within the EU. The results indicate that the average food safety knowledge score among Slovenian tourism undergraduates was 52.6%, raising serious concerns as it is lower than such scores reported in similar studies outside the EU, in Serbia and in Turkey. Slovenian tourism undergraduates demonstrated low elementary knowledge about personal hygiene and the spread of foodborne diseases. Curricula analysis showed the absence of mandatory hygiene and food safety courses at Slovenian tourism faculties, and most students (64%) recognised the need for food safety knowledge education. The findings suggest that neither students’ work experience in the hospitality industry during their studies (compulsory education at the workplace should be provided for all persons involved in food processing) nor following the food safety information on social media could compensate for the lack of formal education. This study underscores the urgency of introducing a comprehensive food safety curriculum in Slovenian tourism faculties to ensure future managers are equipped with essential food safety knowledge.
Religion and Refugee Resettlement in New Zealand: Humanitarianism, Muslims, and the Secular State
Authors:   , Ge Hanyang
Published: July 2024

This thesis examines the encounter between Muslim refugees and the New Zealand state. It argues that the New Zealand state engages with Muslim refugees through an inconsistent secularism. Although this secularism is widely assumed, it is commonly unarticulated. It is also neither legally grounded nor ideologically founded. Nevertheless, state secularism is apparent in actual practices and occasionally also rendered into explicit discourse. I argue that this secularism is politically potent, in part because it often remains implicit. I analyse these secular logics by exploring how different parts of the state engage with Muslim refugees, including in policy development, quota selection, and in the delivery of post-resettlement social services. In formulating my argument, I draw on policy documents and interviews with state and government-funded resettlement actors, as well as with Muslim refugees in New Zealand. At each step of the resettlement process, I show how resettlement actors perceive and frame Islam, including replacing religion by ethnicity, subsuming religion within concerns for social cohesion, critiquing religion as a disruption, and praising religion as a public good. I argue that the most active engagement with the religion of Muslim refugees is found at the greatest distance from the state. I show that this inconsistent secularism has important effects on Muslim refugees.
