Published: October 2022

The relevance of the study of the issues of assessing the quality of educational activities is due to the digital transformation of education, increasing requirements for the level of quality of training, complicating the conditions for organizing the educational process, which determines the need to search for new approaches and technologies. Assessment of the quality of educational activities in the conditions of digital transformation requires the creation of the necessary infrastructure, the formation of an appropriate regulatory, educational, and methodological base. When considering this problem, methods of systematization and generalization were used. The practical significance of the research results is determined by the fact that the conclusions drawn and the proposed scientific and theoretical provisions can be useful to the heads of educational organizations and have the ability to adapt to the conditions of the educational process.

Published: October 2022

In contemporary Russian society, the development of digitalization is tied with the battle against the detrimental effects of COVID-19. In the face of the spread of the infection transmitted primarily through direct human interaction, the need to change the format of this interaction to digital has risen. The dynamics of digitalization were boosted, leading to several problems. There surfaced the issues of technical difficulties, the lack of digital literacy on the part of individual staff members in organizations and some social groups and individuals (primarily those in the socially vulnerable population groups), the limitations of direct interpersonal interaction, the redundancy of digital information, emotional fatigue from having to work and learn only remotely, the cybersecurity of online interactions, a significant increase in digital control over citizens’ lives, the risks of social and psychological tension and distrust of digitalization, technophobia, inability to rationally apply the successes of scientific and technological advancement to improve personal and social well-being.

Authors: Shaposhnikova Tatyana D. , Naydenova Natalia N. , Sukhin Igor G. , Vorontsova Ekaterina A. , Myasnikov Vladimir A.
Published: October 2022

The present study is theoretical and aims to explore and critically evaluate the experience of blended learning demonstrated by countries that have attained a high level of education. Using a complex of theoretical methods, the study provides an analysis of the concept of blended learning, which combines both the traditional forms of education, the methods of distance learning, and innovative e-learning technologies. The models of blended learning found to be most successful in practical implementation are analyzed. The provided examples and recommendations for organizing blended learning in pedagogical education in foreign countries and a discussion of the challenges of its implementation and the possibilities of overcoming them can be useful in the use of blended learning in the Russian system of education, considering the domestic specifics. The study results suggest that the effectiveness of pedagogical education can be ensured by means of a combined implementation of different forms of e-learning and traditional learning – through blended learning.
The Dark Side of Investor Conferences: Evidence of Managerial Opportunism
Authors: Bushee Brian J. , Taylor Daniel J. , Zhu Christina
Published: October 2022

Although the shareholder benefits of investor conferences are well-documented, evidence on whether these conferences facilitate managerial opportunism is scarce. We examine whether managers opportunistically exploit heightened attention around the conference to “hype” the stock. We find that (1) managers increase the quantity of voluntary disclosure leading up to the conference, (2) these disclosures are more positive in tone and increase prices to a greater extent than post-conference disclosures, and (3) these disclosures are more pronounced when insiders sell their shares immediately prior to the conference. In circumstances where pre-conference disclosures coincide with pre-conference insider net selling, we find evidence of a significant return reversal––large positive returns before the conference and large negative returns after the conference––and that the firm is more likely to be named in a securities class action lawsuit. Collectively, our findings are consistent with some managers hyping the stock prior to the conference.
Effects of Material Thickness and Pretreatment on the Interfacial Gap of Translucent Zirconia Restorations with Self-adhesive Resin Cement
Authors: Han S-H , Shimada Y , Sadr A , Tagami J , Tabata T , Nakagawa H , Yang S-E
Published: October 2022

Purpose

The first objective was to determine if the dual-curing of self-adhesive resin cement (SAC) with reduced light penetrating through zirconia had an effect on interfacial gap of zirconia restorations. The second purpose was to examine whether pretreatment methods for universal adhesive affected interfacial gap. The last aim was to compare the microhardness of SAC polymerized under different zirconia thicknesses.

Methods and Materials

This study evaluated self-adhesive resin cement (RelyX U200, 3M ESPE) after different pretreatment with universal adhesive (Single Bond Universal, 3M ESPE) under different polymerization conditions. CAD/CAM inlay cavities were prepared on extracted third molars. Translucent zirconia restorations were milled using Katana UTML (Kuraray). The teeth were divided into three groups: Groups I, II, and III in which the restoration thicknesses were 1, 2, and 3 mm. Each Group had three subgroups according to different pretreatment methods. For subgroup-1, no pretreatment was done on the prepared cavity. For subgroup-2, universal adhesive was applied and light-cured before cement placement (precure method). For subgroup-3, universal adhesive was applied; however, light-curing was done after cement placement (cocure method). After thermo-cycling, the interfacial gap at the restoration-tooth interface was investigated using swept-source optical coherence tomography imaging. Finally, microhardness was measured for SAC under different zirconia thicknesses. For statistical analysis, the interfacial gap was analyzed using two-way analysis of variance (ANOVA) to test the effect of cavity depth and pretreatment. In terms of each cavity depth and pretreatment, the interfacial gap was compared using one-way ANOVA and Scheffe’s test. One-way ANOVA was also performed for comparison of the Vickers hardness results.

Results

Different thicknesses of the restoration resulted in differences in interfacial gaps except between the precure method of Groups I and II (p<0.05). The effect of universal adhesive pretreatment was different depending on the restoration thickness with exceptions in Groups I and III (p<0.05). Vickers hardness number decreased as the low radiant exposure of light was applied (p<0.05).

Conclusion

Interfacial gap of zirconia restorations can differ depending on the material thickness, pretreatment, and activation mode. Reduced light intensity penetrating through zirconia may lead to higher interfacial gap percentage and lower microhardness of the self-adhesive resin cement. Application of a universal adhesive showed similar or reduced interfacial gaps in the cement space.

I atomvåpnenes skygge: Amerikansk atomstrategi og Norge
Authors: Andersen Adelina Trolle
Published: October 2022

Denne artikkelen undersøker hvordan nylig inntrufne endringer i amerikansk atomvåpenstrategi kan påvirke krisestabiliteten mellom USA og Russland og hvilke implikasjoner det kan ha for Norge. Enkelt oppsummert fremstår moderniseringsprogrammene til atomvåpnene, introduksjonen av nye våpen og den deklaratoriske politikken egnet til å undergrave krisestabiliteten fordi det gir USA økte counterforce-kapasiteter. Dette har implikasjoner for norsk alliansepolitikk: Endringene i amerikansk atomvåpenstrategi kan senke terskelen for etablering av bastionforsvaret og øke russisk usikkerhet om norsk tilrettelegging for amerikansk politikk. Med utgangspunkt i tradisjonell teori om krisestabilitet, fremstår flere av de identifiserte endringene i USAs atomvåpenstrategi som destabiliserende. Den tyder på at amerikanske myndigheter ikke aksepterer ideen om den «kjernefysiske revolusjonen». Til tross for dette, skal bekymringen for atomkrig ikke overdrives. Militære analyser må omsettes til politikk. Selv om sannsynligheten for et vellykket førsteslag øker, er det vanskelig å forestille seg politikere som vil risikere atomkrig. Det betyr at avskrekking er mer robust enn hva rene militæranalyser tilsier.
Abstract in EnglishIn the Shadow of Nuclear Weapons: American Nuclear Policy and NorwayThe aim of this article is to provide insight into how recent changes in U.S. nuclear weapon strategy might affect crisis stability between the U.S. and Russia and what implications they might have for Norway. In brief, the nuclear modernization programs, introduction of new systems and changes in declaratory policy may undermine crisis stability because they enhance U.S. “counterforce” capabilities. This has implications for Norwegian alliance policy: changes in U.S. nuclear strategy might lower the threshold for Russia to establish the bastion concept and increase Russia’s uncertainty about the scope of Norwegian facilitation of U.S. policy. Utilizing traditional theories of crisis stability on recent policy changes indicates that the current stability is tenuous. It seems as if subsequent U.S. administrations do not accept the idea of a “nuclear revolution”. Despite this, concerns about a nuclear war should not be exaggerated. Military analyses must be translated into political action. Even if the chance of a successful first strike increases, it is difficult to imagine politicians willing to risk a nuclear war. This indicates that deterrence is more robust than what pure military analyses suggest.

Published: October 2022

Introducción: En el taekwondo, al igual que en muchos deportes, los deportistas con ciertas características físicas o fisiológicas tienen ventaja sobre sus adversarios; por lo anterior, aquellos deportistas que presenten algunas características antropométricas favorables tendrán un mejor rendimiento en la práctica del taekwondo. Objetivo: Revisar y caracterizar el somatotipo de los atletas que practican el taekwondo según categoría y sexo. Materiales y métodos: Revisión en la literatura utilizando criterios de búsqueda prestablecidos con operadores boleanos (“taekwondo” OR “karate” OR “martial arts” OR “judo” OR “mixed martial arts”) AND (“somatotype” OR “body composition” OR “anthropometry”). Se obtuvieron 15 artículos de tipo descriptivo-observacional que se incluyeron en el análisis. Resultados: La muestra total suma 826 atletas, con una edad media de 20,4 ± 1,76 años. Se evidenciaron valores somatotípicos variados según el nivel competitivo, el país y la categoría de peso; sin embargo, se observa cierta prevalencia del componente mesomórfico y ectomórfico en varones. En contraste, para el sexo femenino, aunque se encontraron menos trabajos para analizar, se evidenció una tendencia hacia una clasificación somatotípica central. Conclusión: El somatotipo es tan solo uno de los muchos factores a la hora analizar a un deportista o a un grupo de atletas, pero este puede ser el punto de partida para poder identificar posibles talentos en este deporte.

Study on inefficient land use determination method for cities and towns from a city examination perspective
Authors: Jiao Hong , Huang Jiali
Published: October 2022

With the rapid advancement of urbanisation process, the total development of urban construction land is restricted, and the inefficient, extensive and sprawling traditional urbanisation mode is hard to sustain, bringing current incremental planning-based city development mode to gradually convert to stock planning. Under the background of stock planning, the inefficient urban land becomes the first choice for potential excavation and land vitalisation. Besides, under the background of new urbanisation construction, judging inefficient urban land and comprehensively boosting the redevelopment of those lands is the optimal path to promote land saving and intensive use. This paper starts from city examination, extracts the indexes from city examination for judging inefficient urban land use, and analyses urban construction land by land block. Then, the YAAHP software is used to determine the weights of indexes, and actual case is taken into the weights of various factors for analysis, so as to obtain the land use efficiency score of each land block and the entire city. The land block getting a low score will be renovated and transformed, which is an approach for improving land use efficiency and land intensiveness with the lowest cost; in the process of establishing an inefficient urban land use index system, the indexes of city examination are also supplemented and perfected, providing an optimal solution for future identification and determination of inefficient urban land use.
A Sentiment Analysis Method Based on Bidirectional Long Short-Term Memory Networks
Authors: Zhang Haifei , Xu Jian , Lei Liting , Jianlin Qiu , Alshalabi Riyad
Published: October 2022

Although the traditional recurrent neural network (RNN) model can cover the time information of the whole sentence theoretically, the gradient is dominated by the short-term gradient, and the long-term gradient is very small, which makes it difficult for the model to learn the long-distance information, and thus the effect of RNN on long text sentence recognition is poor. The long short-term memory network (LSTM) introduces the gate mechanism, especially the forgetting gate, which improves the disappearance of the gradient of RNN. Therefore, LSTM can store long text information and remove or increase the ability of information interaction by adding gate structure, which has natural advantages for long text processing. Based on the word vector matrix of GloVe model, on the open-source comment sentiment140 data set, we use the TensorFlow framework to construct the LSTM neural network and divide the data into the training set and test set based on the ratio of 4:1, design and implement the sentiment analysis published by Twitter users based on LSTM model, and then propose the bidirectional LSTM (Bi-LSTM) sentiment analysis method. The experimental results show that the accuracy of bidirectional LSTM is higher than that of unidirectional LSTM in sentiment analysis.

Research on threat assessment problems of island air defence system based on the leader-follower model
Authors: Wang Y. , Cheng Y. , Shan X. , Mou J. J. , Zhou L. , Salama Mohamed
Published: October 2022

To study the command and control system in an island air defence system under the background of systemic conflict, this paper proposes a new modelling method based on the opinion dynamics leader-follower model to simulate the target threat assessment process in the command and control activities. Through example simulation, it is obtained that in a centralised command and control system, a command post (CP)-led model can provide the most accurate threat assessment results, but it consumes a longer time. While in a distributed command and control system, a model without a leader can provide a target threat value accurately and quickly. The consistency of simulation results and actual situation indicates that, at present, under a high degree of battlefield information sharing, it is necessary to down-pass the authority of the CP to improve operational efficiency. In summary, the proposed model can comprehensively reflect the process that the island air defence system assesses the threat of an attacking target, and it gives a new idea for investigating the command and control procedure and system of the island air defence system.
Studying a matching method combining distance proximity and buffer constraints
Authors: Wang Fengping
Published: October 2022

In order to achieve fast matching of global navigation satellite system (GNSS) track data and vector road network data, a rough-to-fine matching method combining distance proximity and buffer constraints is studied. The GNSS track data is preprocessed: A rasterisation method is used to eliminate the low-quality track data and obtain the binary graph; then, the road centrelines are obtained by a skeleton extraction method; the thinning data is converted into line segments or closed lines starting from nodes by the boundary tracking method, which is stored in the vector form. Finally, the boundary tracking method is used to convert the thinning data into closed lines and store them in the vector form. A two-layer rough-to-fine matching strategy is applied: First, the changing state of the road arc is determined according to the rough matching strategy of road segment distance. Next, according to the buffer constraint criterion, a rectangular or circular buffer is selected to achieve precise matching of road network data. The results show that the proposed method has good matching effect, which is especially suitable for working with more GNSS track data.

Published: October 2022

As the primary killer of health, the class of infectious diseases is the greatest threat to humanity. At present, international methods of studying the large-scale spatial transmission of sudden infectious diseases from the perspective of dynamics can be divided into two categories. On the one hand, top international biomedical and medical teams discuss the restraining effects of some prevention and control strategies on infectious diseases, such as smallpox, malaria, hand, foot and mouth disease and pandemic influenza, from the perspective of pragmatism. On the other hand, researchers in theoretical physics and network science tend to use compound population network models to explore the internal dynamic mechanism of spatial transmission of infectious diseases. This paper establishes a Lotka–Volterra dispersal predator–prey system in a patchy environment. It shows the existence of model boundary equilibria and asymptotic stability under an appropriate condition. This paper adopts the method of global Lyapunov function and the results of graph theory. We also consider a predator–prey dynamical model in a patchy environment, where the prey and predator individuals in each compartment can travel among n patches.

Authors: Wu Lei
Published: October 2022

Continuing education platforms are faced with problems such as the aging of online learning platforms and backward technology. The data center network is an essential infrastructure supporting the big data and cloud computing platform continuing education network. It is widely used for data-intensive and massively parallel computing tasks. The paper proposes a continuing education network data center management model based on this research background. At the same time, this paper proposes a real-time encryption method for distributed data in a multi-layer differential continuing education network based on fractional differential mathematical equations. The experimental study found that the fractional differential mathematical equations method can effectively control the stability of data transmission of continuing education receipt networks. This algorithm improves the efficiency of network data operation and controls the cost of encryption. The research results of this paper provide technical support for network education.
Economic Research on Multiple Linear Regression in Fruit Market inspection and Management
Authors: Zhang Fan
Published: October 2022

Based on the hypothesis test of multiple regression models, this paper discusses three different implementation methods of permutation tests and analyzes their manifestations and application effects in regularization models. The two implementation methods are used for the first time to discover the Markov edge of the regularization model, which expands the application range of the replacement test method. The fruit market uses an e-commerce platform to connect farmers, leading enterprises, financial institutions, and logistics companies. Using information technology as a means, it uses the network to implement online transactions, online financing, online pledges, and online management to achieve information. New flow of finance, capital flow and logistics. Based on the theory of information asymmetry, system theory, and synergy theory, it is found that there is a linkage effect between the online supply of fresh agricultural products and the risk system. Various interest systems have affected the risks of online supply of fresh agricultural products by affecting the risks of financing companies, e-commerce platform risks, financial institution risks and other risks. The quantitative ridge regression model can well solve the shortcomings that MRLM-P cannot be applied to collinear data sets; on low-dimensional data sets, there is a classic regularization model of Markov edge discovery performance similar to MRLM-P; permutation The two newly-implemented implementation methods are slightly inferior to the previous implementation methods; Markov edge theory can effectively perform “dimensional reduction” operation on the spectral information matrix, and both correction models can well reflect the spectral information of the detection object. Dependence. information on platform financing companies, and assume regulatory responsibilities in the transaction process. Financial institutions should also carefully select cooperative e-commerce platforms and determine the appropriate financing rate based on the results of risk prediction, so as to effectively reduce the risk of online supply is of great significance.

Magnesia Composites Formation as a Result of Furniture Production Wood Waste Processing
Authors: Miryuk Olga
Published: October 2022

The article outlines the problem of accumulation of short-fibered waste generated during chipboard sawing. Intense impact on the material determines a high level of technological availability of wood waste. The research objective is to create magnesia composite materials for various purposes based on chipboard processing waste. Moulding sands containing caustic magnesite, fly ash, aluminosilicate ash microsphere, wood waste and magnesium chloride solution have been studied. Change in the ratio of moulding sands’ components provided production of finely dispersed composite material, and granules of cylindrical and spherical shapes. Composite materials of coarse-pored structure have been developed on the basis of magnesia granules and hybrid magnesia-ash binder. Combination of layers of finely dispersed and coarse-pored materials has been proposed to form composites of variotropic structure with density 780–840 kg/m3 and strength 9.7–11.9 MPa. Combined structures’ stability is achieved due to the high adhesive ability of magnesia binders and genetic commonality of various layers.

Published: October 2022

Safflower is currently primarily cultivated as an industrial crop for its oil, which is used for food and industrial purposes, while the by-products can be used for animal feeding. Traditionally cultivated in the Mediterranean area, it was abandoned in the past for other oil crops, such as sunflower. However, it is now returning to be interesting due to its adaptability to low-input cultivation practices, especially when sown in autumn. The main aim of this study is to present a Life Cycle Inventory of safflower grown in a Southern European country, i.e. Italy, based on primary data on agricultural practices used in this country. The study was carried out following ISO 14040 and ISO 14044. Data were collected from experimental fields of the University of Perugia, to ensure a specific and accurate data collection for the definition of the complete supply chain. The reference unit of this study was defined as 1 ha. The stages from raw materials production to seed harvesting were considered. The data presented will be useful to increase the existing knowledge of safflower production in other Mediterranean countries.

Published: October 2022

The ever-increasing amount of greenhouse gas emissions are forcing countries and the industrial sector in particular to develop ways to improve the manufacturing industry and reduce the amount of emissions created in compliance with the requirements of the European Green Deal initiative. However, all modifications must be under local laws and European directives. The purpose of this work is to analyse existing laws, regulations, and directives, both local and European, to identify limiting factors and factors that contribute to a more active introduction of systems for capturing, using, and reducing the amount of carbon dioxide created in production processes. The results of this analysis will determine the strengths and weaknesses of the local manufacturing sector and its ability to meet evertightening requirements.

The Summary for Urban Policymakers (SUP) initiative provides a distillation of the IPCC reports into accessible and targeted summaries that can help inform action at city and regional scales. Volume I in the series, What the Latest Physical Science of Climate Change Means for Cities, identified the ways in which human-induced climate change is affecting every region of the world, and the cities and urban areas therein. Volume II, Climate Change in Cities and Urban Areas: Impacts, Adaptation and Vulnerability, assessed the feasibility and effectiveness of different adaptation options. To achieve climate resilient development, synergies between policies and actions for climate change adaptation, mitigation and other development goals are needed. This third volume in the series, What the Latest Science on Climate Change Mitigation Means For Cities and Urban Areas offers a concise and accessible distillation of the IPCC Working Group III Report for urban policymakers. The 21st century is characterized by a rapidly growing urban population, urban land expansion and associated rise in demand for resources, infrastructure and services. These trends are expected to drive the growth in emissions from urban consumption and production through 2100, although the rate of urban emissions growth will depend on the type of urbanisation and the speed and scale of mitigation action implemented.

Los Grupos de Apoyo a la Cultura Académica GRACA de la Universidad del Valle son una de las estrategias de apoyo a los procesos académicos de los estudiantes. Esta estrategia interdisciplinaria está a cargo del Grupo de investigación Leer, Escribir y Pensar de la Escuela de Ciencias del Lenguaje, la REDLEES Nodo Univalle y las Facultades y programas interesados en apoyar los procesos de lectura, escritura y oralidad en las disciplinas. El carácter interdisciplinario de los GRACA obedece al propósito de responder a las particularidades de los discursos que circulan en la comunidad académica y "…son una experiencia única en América Latina por su carácter interdisciplinario y porque sitúan la lectura y la escritura al interior de las facultades". Paula Carlino (2017) A partir del análisis y la sistematización de los registros recogidos sobre las interacciones de los participantes en el espacio de las tutorías entre pares; de las intervenciones en el aula; de las actividades de capacitación y promoción de los Grupos en la Universidad; de las percepciones de los tutores, tutorados y docentes sobre el trabajo en los grupos y el valor formativo de estas actividades en la institución nace este texto que destaca una metodología para: la descentralización de los procesos de lectura, escritura y oralidad en la universidad, el trabajo entre pares e iguales, las tutorías interdisciplinarias, el apoyo a estudiantes y docentes en el aula. En síntesis, este texto es un aporte a la Alfabetización Académica en la universidad desde una perspectiva interdisciplinaria y bajo el compromiso institucional para mejorar los procesos de construcción de conocimiento en las disciplinas.

أصبحت استراتيجيات التعلم الحديثة من أهم الأدوات التي يهتم بها لما لها من أثر بالغ في تحقيق الأهداف التربوية . (المصالحة وأبو الحاج ، 2016 ، 39) لذا هدفت الدراسة الحالية إلى معرفة فاعلية استراتيجية مقترحة على وفق مهارات ما وراء المعرفة في تحصيل طالبات الصف الرابع العلمي في مادة التربية الإسلامية . ولتحقيق هدف البحث صاغت الباحثة الفرضية الصفرية ، لا يوجد فرق ذو دلالة إحصائية عند مستوى دلالة (0,05) بين متوسط درجات المجموعة التجريبية والتي ستدرس وفق الاستراتيجية المقترحة (B) ومتوسط درجات المجموعة الضابطة والتي ستدرس وفق الطريقة الاعتيادية في الاختبار التحصيلي في مادة التربية الإسلامية . اقتصر البحث الحالي على عينة من طالبات الصف الرابع العلمي لإحدى المدارس الصباحية لمحافظة بغداد الرصافة الثانية للعام الدراسي (2019-2020) وتطلب هدف الدراسة إلى وجود أداتين وهما الاستراتيجية المقترحة على وفق مهارات ما وراء المعرفة واختبار التحصيل لمادة القرآن الكريم والتربية الإسلامية ، التي تم إعدادهما من قبل الباحثة وعرضهما على مجموعة من الخبراء في اختصاص طرائق التدريس والمقياس والتقويم وتم الاتفاق بنسبة (100%) .
أما اختبار التحصيل فيحتوي على (40) فقرة من نوع الاختيار من متعدد ، وتحققت الباحثة من صدق الاختبار وأيضاً إيجاد معامل الصعوبة والتمييز الثابت لفقرات الاختبار باستعمال معادلة كيود-ريتشاردسون (20) ، إذ بلغ معامل الثبات (0,83) ، وبعد أن كافأت الباحثة بين المجموعتين بالمتغيرات (العمر بالشهور ، مستوى الذكاء ، التحصيل الدراسي للآباء والأمهات) ، طبقت تجربتها وفق الموضوعات للكتاب المقرر والخطط التدريسية والأهداف السلوكية التي أعدتها بنفسها لكلتا المجموعتين ، بعد ذلك أجرت الباحثة الاختبار لمجموعتي البحث ، وتم تصحيح الاختبار وتحليله إحصائياً باستخدام الاختبار التائي لعينتين مستقلتين توصلت إلى وجود فرق ذي دلالة إحصائية عند مستوى دلالة (0,05) لصالح المجموعة التجريبية وفي ضوء ما توصلت إليهِ الدراسة أوصت الباحثة اعتماد الاستراتيجية أنموذجاً تدريسياً فاعلاً في التحصيل ، أما ما اقترحته الباحثة إجراء دراسة مماثلة للدراسة الحالية على مواد مراحل دراسية أخرى .
