Innovation in thinking and practice path of digital economy based on big data analysis to promote high-quality development of agricultural service trade
Authors: Zhang Yanhong
Published: September 2023

In order to coordinate the digital geographic planning of agriculture and clarify the grasp of agricultural integration and digital development, by building a connected coordination model of the digital economy and the high-quality growth of the agricultural services trade, this article is confirmed. First, the fundamental workings of the digital economy and their spatial spillover effects on the high-quality growth of the agricultural services sector are examined. To evaluate each method’s level of development, the TOPSIS methodology and the entropy value method are linked, and a coupling coordination model is created. The production of the high-quality agriculture service trade and digital economy index system follows. In the end, the empirical study of coupling coordination was carried out using data from each province in China from 2010 to 2020 as the original sample. The findings indicate that before 2015, in all provinces, the coupling coordination degree of the development of the agricultural service trade and the digital economy was less than 0.2. The coupling coordination degree showed a tendency of moderate expansion from 2016 to 2020, increasing by 583.33% from 2010 to 2020. This shows that as the digital economy has expanded, the agriculture services sector has also developed in a high-quality manner.

Authors: Asquer Carla , Romagnoli Francesco
Published: September 2023

The selection of a local and sustainable use of biogas, and biogas feedstocks, towards the upgrading process to biomethane, is a key aspect towards more consistent energy planning within the frame of the EU Green Deal and Sustainable Development Goals. In this paper, four biomethane production and utilization pathways were assessed in the view of economic, environmental, technological, and social dimensions compared to a reference scenario in which direct biogas use in a cogeneration unit is assumed. The technologies analyzed included membrane systems, amine scrubbing, water scrubbing, and biological methanation, regarding the Sardinian context. The impact assessment was carried out using the TOPSIS method. As an output, thirteen consistent indicators reflecting the holistic aspect of sustainability were designed and proposed based on an in-depth literature review and the authors’ technological knowledge. The results show that the reference scenario was the preferable one. In terms of environmental and social considerations, biological methanation emerged as the most environmentally and socially responsible alternative. From the economic perspective, all the upgrading options depicted similar results. The technological-oriented weighting showed that the two most widespread upgrading options highlighted the optimal results.
An elastoplastic constitutive model for assessing ground settlements induced by deep excavations
Authors: El-Arja Hiba , Burlon Sébastien , Bourgeois Emmanuel
Published: September 2023

Ground movements induced by deep excavations may cause damages on neighboring existing buildings. Finite element simulations generally give acceptable estimates of the horizontal displacements of the retaining wall, but results are less satisfactory for the vertical displacements of the ground surface behind the structure. A possible explanation is that most constitutive models describe volumetric strains in a simplified way. This paper proposes an elastoplastic constitutive model aimed at improving the prediction of vertical displacements behind retaining walls. The model comprises a single plastic mechanism with isotropic strain hardening, but has a specific flow rule that allows to generate contractive plastic strains. Identification of the parameters based on triaxial tests is explained and illustrated by an example of calibration. A numerical analysis of a well-documented sheet pile wall in sand in Hochstetten (Germany) is presented. The results given by the model are compared with the measurements and with those obtained using the Hardening Soil Model. The potential advantages of the proposed model are then discussed.
The Conceptual Matrix of Media Linguistics in the XXI Century: A Case Study of The PIE News
Authors: Kharkovskaya A. A. , Golubykh A. A.
Published: September 2023

The present paper is dedicated to describing the conceptual framework of contemporary English-language media linguistics, using materials from the informational educational news website, The PIE News. The PIE News serves as a vital conduit for disseminating information about professional activities, playing an increasingly pivotal role in the global educational landscape. In the current geopolitical context, there is a heightened focus on enhancing educational systems and reshaping the priority positions of professions within disciplinary policies. Consequently, the integration of new technologies into the educational process becomes paramount for the successful development of competencies required to train specialists in popular fields. The aim of this research is to analyze the linguistic characteristics of English-language mass media texts concerning international professional educational activities. The scientific novelty of this study lies in its examination of the functional potential of linguistic markers within the texts. The authors have identified that educational discourse is manifest not only in the body of the publications but also in their headlines, affirming the axiological orientation of the contemporary professional landscape. The analysis of linguistic markers reveals that the metaconcept ‘Education’ encompasses concepts such as “updated educational programs,” “methods of financial support,” “expanding the global network of educational centers,” “collaborative initiatives,” and “enhanced competitiveness.” The linguistic features of these markers are characterized by various abbreviations, providing evidence of the universal principle of language economy in modern virtual mass media discourse. However, these abbreviations, while efficient, can occasionally complicate information comprehension. As a result of this study, the authors draw conclusions about an emerging trend in education characterized by the development of short-term educational projects, primarily in a distance format, combined with professional activities, thereby fostering greater workforce training mobility within the modern labor market.
Metaphor as Invective in the Genre of Internet Commentary: A Focus on German Political Discourse
Authors: Kuchina D. D.
Published: September 2023

This article presents the results of a linguo-stylistic analysis of a Germanlanguage commentary within the context of public political internet discourse. The analysis aims to identify distinctive features specific to this genre. Empirical material consists of over 200 comments on internet posts made by the German political party “Alternative for Germany,” selected through random sampling. The study applies both general scientific and linguistic methods, such as discourse analysis and contextual analysis. The relevance of this chosen topic is justified by the need for research in the field of internet linguistics, particularly in addressing genre-related issues. The goal is to determine, identify, and describe the characteristic features of commentary as an internet text. The article thoroughly examines the approaches taken by German linguists to define the concept of “invective,” encompassing lexical-semantic perspectives, speech act theory, and post-structural discourse analysis. Additionally, the analysis of the material reveals that invective is a hallmark of German political internet discourse, with manifestations in both explicit and implicit forms. The article discusses implicatures, arising through irony and metaphorization. The author concludes that metaphor can serve as a tool of persuasion. Metaphor, as a persuasive device, involves the intentional alteration of the mental representation of a given object based on the metaphorical image imposed by the manipulator. This typically includes exaggeration in some aspects of the metaphorically represented phenomenon while diminishing others.
Strategies of (De)Legitimation of COVID-19 Vaccines in Tanzanian Political Speeches
Authors: Selenya J. J.
Published: September 2023

The COVID-19 pandemic sparked worldwide efforts to combat the health crisis, including vaccine development and distribution. However, varying political responses to vaccination policies complicated public discourse and influenced vaccine acceptance. This research paper employs critical discourse analysis (CDA) to compare (de)legitimation strategies used in Tanzanian political speeches by two presidents: late President Magufuli and current President Samia Suluhu Hassan. The study focuses on their approaches to legitimizing or delegitimizing COVID-19 vaccines in 2021. Two speeches were purposefully selected based on their relevance to vaccination decisions. President Magufuli employed strategies such as discrediting experts, discrediting others, denial, conspiracy theories, and making accusations to delegitimize vaccines. In contrast, President Samia justified vaccine acceptance using strategies such as authorization, moral evaluation, emotional appeals, and rationalization. These differences in approach can be attributed to their respective ideologies. President Magufuli, a populist leader, displayed scepticism towards Western medicine and promoted local solutions, while President Samia presented herself as a pragmatic leader who prioritizes scientific solutions and international cooperation in addressing health crises. The findings shed light on the complexities of public health communication and vaccine acceptance in Tanzania.
“Newspeak” in Contemporary German Political Discourse
Authors: Shesterina E. A.
Published: September 2023

This article examines the concept of “newspeak,” created by J. Orwell in his novel “1984,” which functions as one of the means of manipulating the political consciousness of people. The article focuses on the linguistic manifestation of newspeak in the speech behavior of modern German politicians. It reveals two main functions of newspeak in the speech of modern German politicians: confusion and reinterpretation of established concepts. The article explores the corpus of lexical means of German political newspeak, which are realized in the form of framing, empty phrases, paradoxical word constructions, borrowings, neologisms, clericalisms, lexemes with ambiguous meaning, and words with multiple meanings. Among the grammatical means peculiar to newspeak in German political discourse, the article describes the inclusive pronoun “wir,” passive voice, and the conjunctive irrealis in combination with the adverbial modifier of manner. The pragmatic means of realizing newspeak in German political discourse include the imposition of presuppositions, weak efforts to fulfill the intentions, and hyperbolization. The conclusion is drawn that, unlike in totalitarian societies, politicians in democratic countries use newspeak to compensate for the failures of their party, which turns out to be unable to fully implement its declared intentions, mainly through linguistic manipulations.
Konsep Merdeka Belajar Bagi Anak Usia Dini Perspektif Ki Hajar Dewantara
Authors: Masliyana  , Muhammad Nasir
Published: September 2023

The concept of independent learning is a concept that emphasizes the ability to think independently. Merdeka is here aimed at providing educators, students and parents with comfort and enjoyment in learning to facilitate innovation and creativity. This is based on the fact that individuals with an independent disposition are more likely to experience freedom in using their innate abilities effectively. Talking about the concept of freedom to learn is actually not something new, but has been propagated for a long time by Ki Hajar Dewantara. The ideas and concepts put forward by him have contributed to the formation of a more organized and well-defined framework in the field of education in Indonesia. However, in reality, currently it can be said that the quality of education still needs to be improved, especially in Early Childhood Education Institutions. So the aim of the research was to describe the concept of independent learning for young children from the perspective of Ki Hajar Dewantara. This research uses qualitative methodology, namely descriptive analysis which includes library research. Research findings show that freedom to learn is one of the efforts to achieve humanist education. One of the educational ideas that is very important to be disseminated in the learning practices of the society 5.0 era. According to Ki Hajar Dewantara, the presence of free learning for young children fosters a sense of unlimited freedom in carrying out play activities. Children will freely explore as an indication that children have physical and psychological independence. Not only that, Ki Hajar Dewantara included the concept of freedom of learning as one of the five basic principles of Panca Dharma which includes "freedom or independence, culture, nature, nationality and humanity".

Direct Control of Pt Film Orientation for Growth of (100)-oriented PZT Films
Authors: Quoc Trinh Bui Nguyen
Published: September 2023

We investigated highly (100)-oriented PZT films directly grown on Pt films coated on RuO2/SiO2/Si substrates via sputtering method. By controlling the preferred (100) orientation volume of the Pt films, we confirmed the effectiveness of high (100) orientation of Pt films suitable for the growth of highly (100)-oriented PZT films. Particularly, as the (100) orientation region of Pt film is larger than 90%, the PZT film with 95% of (100) orientation region can be formed, without using any seed layer as well as epitaxial growth process. We found that a highly (100)-oriented PZT film possesses large grains with a size of 150 nm, and it possesses twice remanent polarization of 58 mC/cm2 and coercive electric field of 148 kV/cm with the relatively low leakage current less than 10-6 A/cm2 at the applied voltage of ± 4 V. One can convince that the technological process for highly (100)-oriented PZT films is simple, and it is promising for ferroelectric and piezoelectric applications in wide ranges.
The Influence of the Scalar and Vector Anomalous Couplings on the Z-production at ILC in the Randall - Sundrum Model
Authors: Giang Bui Thi Ha
Published: September 2023

An attempt is made to present the effect of the scalar and vector anomalous couplings on  scattering process with polarized initial beams in the Randall-Sundrum model. We have studied the contribution of radion, Higgs and gauge bosons on the Z-production cross-section at International Linear Colliders (ILC). The cross-section depends strongly on the polarization of  initial beams, the center of mass energy  and model interaction parameters. The obtained results indicate that with the vector anomalous couplings included Z boson and photon, the cross-sections for the Z production are much larger than that with the scalar couplings included radion and Higgs under the same conditions.

Authors: Than Nguyen Thi , Trang Tran Thi Quynh , Tung Pham The , Lan Vo Thi Thuong
Published: September 2023

: Real-time PCR is currently one of the most powerful molecular approaches and is widely used in molecular biology diagnostics. Today, many real-time PCR systems differ in the thermal block, the excitation source, the fluorescence detection system, and the data analysis software. Therefore, using different systems may affect the detection limit of biological samples. Our study aims to optimize the threshold to ensure the amplification efficiency (E) and correlation coefficient (R2) of the standard curve used to quantify LINE-1 methylation on three real-time PCR systems, including: Applied Biosystems™ 7500, QuantStudio™5 Dx; and abCyclerQ (AIT Biotech). We determined a proper threshold to build a standard curve on the three systems, which ensures the correlation coefficient (R2) and the amplification efficiency (R2 > 0.999, E ≥ 95%). Therefore, it is possible to use interchangeably in Applied Biosystems™ 7500, QuantStudio™5 Dx, and abCyclerQ (AIT Biotech) in LINE-1 methylation analysis.

The human immune system is very effective in eliminating pathogens that attack us in everyday life. However, in the case of HIV infection, it fails to clear all infected cells, resulting in a disease that remains incurable to date. Our study reveals that HIV-infected cells express higher levels of immune checkpoint markers and 'do not kill me' signals, helping them evade immune detection.
Modelo de inteligencia computacional para la legalización de cultivos ilícitos en Colombia, a partir de la teoría de juegos cooperativos
Authors: Beltrán Rodríguez Carlos Alirio
Published: September 2023

La producción de cultivos ilícitos de coca en Colombia comenzó en la década de 1970 debido a los problemas que los campesinos enfrentaron para acceder a los mercados legales y al aumento del conflicto armado, lo que trajo consigo la desvalorización de sus tierras y el desplazamiento forzado. El aumento de los cultivos ilícitos en Colombia desencadenó una Guerra contra las Drogas desde Estados Unidos, que se materializó en el Plan Colombia, como una estrategia antinarcóticos y contrainsurgente a gran escala que desató una enorme violencia contra las comunidades campesinas en el sur de Colombia. Los costos sociales derivados de la producción y el consumo de la droga en ambos países han convertido en una prioridad poner fin a la fabricación y el tráﬁco de drogas ilícitas, utilizando controles fronterizos, interdicción de cargamentos de droga y la destrucción de los laboratorios y precursores químicos utilizados en la producción de cocaína, sin embargo, el trabajo para evaluar la eficacia de las políticas de control de drogas ha sido muy bajo. De acuerdo a lo anterior esta propuesta doctoral se centra en diseñar un modelo de inteligencia computacional a partir las diferentes di­mensiones de la política de drogas en el país y el desarrollo sostenible, teniendo en cuenta los vínculos entre desarrollo social, desarrollo económico, sostenibilidad ambiental, la búsqueda de sociedades menos violentas, justas e inclusivas, y la creación de alianzas, es un factor de gran relevancia, para el diseño de una política de drogas que resulte más efectiva, eficiente y menos costosa. Entre las principales variables a analizar en esta propuesta de investigación se debe tener en cuenta la efectividad de las políticas implementadas por el Estado frente a la oferta y la demanda de drogas, los delitos conexos al narcotráfico, el lavado de activos, las organizaciones crimina­les vinculadas al narcotráfico, las posturas de la política exterior colombiana en torno a los cultivos ilícitos y la política de drogas.

Published: September 2023

La producción de café en todo el mundo ha aumentado significativamente en la última década y con esto han surgido diferentes maneras para consumir y procesar los granos de café. Una de las formas alternativas para diversificar su uso es mediante la extracción de aceite, los cuales presentan un gran aporte por su alto contenido en antioxidantes los cuales no son aprovechados en una taza de café. Comercialmente por causa de la fuerte demanda de aceites por parte de la industria de cosméticos y alimentaria, los extractos de aceite de café son un producto apetecido por sus propiedades, las cuales se relacionan con el método y condiciones de extracción, costo productivo y calidad final del aceite, entre otras. En la actualidad se conocen varios métodos para extraer aceites; entre los más usados están la extracción por fluido supercríticos, Soxhlet y extrusión mecánica. El prensado mecánico es una de las técnicas más utilizadas para obtener aceites de grado alimenticio debido a que no requiere el uso de solventes que pueden generar contaminantes ambientales perjudiciales para la salud humana. En la presente investigación se analiza esta técnica de extracción de aceite con criterios como rendimiento, valor nutricional del aceite obtenido, la conservación de los compuestos activos y costos operativos. La metodología se enfoca en cuatro fases: caracterización del grano de café, preparación de la muestra para extracción, extracción por extrusión y análisis del aceite extraído. Los resultados preliminares indicaron que el rendimiento se ve directamente relacionado con el grado de tostión alta, la conservación de compuestos activos y costos operativos son afectados a tostiones bajas. No obstante, se determinaron las condiciones apropiadas del proceso de extracción de aceite de café relacionándolos a través de un método analítico. En el presente estudio se pudieron determinaron algunas características fisicoquímicas del aceite de café obtenido mediante extracción mecánica estas fueron: el índice de refracción el cual varió entre 1,46 y 1,49, la densidad calculada a 20°C que estuvo entre 0.90g/L y 1.00g/L y la viscosidad con un valor menor que 3.00 en unidades de cP. Estas características se relacionan con el grado de pureza y calidad con lo cual se pudo asegurar que el aceite mantuvo la apariencia y estado físico químico cómo aceite claro y líquido viscoso durante un tiempo máximo de 32 días y bajo circunstancias favorables de almacenamiento.

The Transylvanian Orthodox Church seems to have borrowed a lot of non-Orthodox practices from the confessions it lived with during the 16th-17th centuries, influences that can still be identified today. It is enough to think about the specifics of the funeral sermons in Transylvania, which are composed in a special style, including the famous "forgiveness", a style that seems to be borrowed from the Protestant confessions existing in Transylvania. In this context, we propose a research to demonstrate that some local practices of the Orthodox Church have been influenced by liturgical interferences from other Churches, by inventorying and presenting the research directions embraced by renowned researchers in the field, in order to know the historical context in which the long contacts between Romanians and the neighbouring nations took place, the factors that determined them, the exponents of each camp and the periods in which these processes took place
THE PRACTICE OF PRAYER IN THE JERUSALEM CHURCH ACCORDING TO THE BOOK OF ACTS
Authors: AYUCH Daniel
Published: September 2023

One of the recurring elements in the Lucan Diptych is precisely the practice of prayer by all its characters. From Jesus to Mary and the disciples, and from the women to the first Christian community everyone is said to pray in the Gospel and the Book of Acts. The initial path of the Church is marked, above all, by the action of the Holy Spirit, who transforms the Apostles into witnesses of the Risen One who express themselves not only in the Word but also in the shedding of their own blood. Their testimony spread rapidly from Jerusalem and Antioch to the West until it reached the capital of the empire in Rome, as the Lord said in Acts 1:8: “you will receive the power of the Holy Spirit which will come on you, and then you will be my witnesses not only in Jerusalem but throughout Judaea and Samaria, and indeed to earth's remotest end.” The entire book of Acts reveals a praying Church, a community of faithful deeply rooted in prayer
THE UNION OF MAN AND CREATION WITH GOD, REFLECTED IN THE "MEDITATIONS" OF SAINT MAXIM THE CONFESSOR
Authors: CÎRSTEA Cosmin Iulian

The union of man and creation with God, reflected in the "meditations" of St Maximus Confessor. God created all that exists out of love, wishing to share His eternally good existence with all creation. But the world cannot enter into a personal relationship with God, not being a person. That is why the Creator has placed in its midst man, who is the rational and personal representative of creation. He has been endowed with the vocation of uniting all that exists within himself and drawing the whole world into the most intimate communion with God. St Maximus Confessor describes this vocation of man through a series of five mediations that Adam had to carry out: mediation between man and woman, paradise and the inhabited world, heaven and earth, the intelligible and the sensible, the created and the uncreated
THE HUMAN BEING – A BEING OF GRACE AND A DIALOGICAL STRUCTURE
Authors: PETROV George Daniel
Published: September 2023

Today, perhaps more than ever, the definition of the human being as a being of grace with a dialogical structure is imperative, because of contemporary challenges that threaten the person with desacralization, reducing him or her from the crown of creation to a simple egocentric individual heading towards nowhere. The removal of man from the sacred, through society's increasingly ephemeral offerings, threatens the dignity of the human being as a graceful being capable of dialogue and communion with the Persons of the Holy Trinity, instead offering him material elements that can in no way satisfy man's aspiration to the absolute. If, after creation, the human soul spiritualized the body, raising it to the state of dialogue with God, today the soul is threatened with "materialization", in the sense of reducing human nature to the sensory.
ORTHODOX GNOSEOLOGY REFLECTED IN THE HOLY GOSPEL OF SAINT JOHN THE APOSTLE AND EVANGELIST

In order to get to the knowledge of God, we must first know ourselves and the purpose that God has for each individual human person. Those who had the sense of spiritual knowledge knew God, but pretended not to know Him, perverting their consciences and freely preferring lies instead of Truth. Knowing God is done through prayer, through knowing the reasons planted by Him in creatures, and after that, according to the fulfillment of His commandments. Love is the perfect way to get to the knowledge of God.

The examination of students’ motivation towards lessons is an important aspect of educational studies. The constructivist approach significantly impacts the improvement of students’ motivation. The present study aims to examine the use of the 5E learning model with concept maps to support students’ motivation and compare the 5E approach and the classical approach to teaching chemistry in terms of motivational dimensions. The main subject of this study is an assessment of students’ motivation using the 5E learning model, which promotes student-centred teaching. The study was conducted with 100 8th-grade lower secondary school students who attended a school in the Turkish Republic of Northern Cyprus (TRNC) during the spring semester of the 2018/19 school year. The study was conducted with two randomly selected groups: experimental (EG) and control (CG). The lessons of the EG were taught using the 5E Learning Model Improved with Concept Maps, while lessons of the CG were conducted using the current, conventional teaching method. The Motivated Strategies for Learning Questionnaire (MSLQ) was applied as a data collection tool in the study. Descriptive statistics and Multivariate Analysis of Variance (MANOVA) were used in data analysis. As a result, it was determined that the EG students’ motivation scores showed a significant difference from the CG students’ motivation scores. Furthermore, a significant difference was established between the EG and CG students’ intrinsic goal orientation and test anxiety post-test scores. Although the EG students’ averages for other sub-dimensions were higher than the CG students’ averages, no significant difference was found between the groups.
