The article is about the reasons of the decline of the Western European and USA youth protest movement in late 60s of the 20th century. According to the authors, the main reasons for the decline of the Movement are: the spontaneity of the protests, the absents of the joint coordination of actions, mistrust political institutions, the narrowness and limitations of ideas and slogans). The change of attitude towards the youth by the government circles and public of the Western countries in the early 1970s played an important role in the minimization of protest activity. As the result of it was the development of a fundamentally new youth policy based on the “whip and gingerbread” method: on the one hand, there was a strengthening of the repressions against riots participants, and on the other hand, the involvement of youths representative into political, state, business and public institutions with the aim of integration began protest activists in public life. Finally, the new trends in the social and political development of the Western countries in early 1970s become the significant factor in the decline of the protest movement. Such trends included changes in economic, political and cultural interactions in countries of Western Europe and USA, in particular the deterioration of the economic situation, as well as the extension of the social elite at the expense of students and graduates of technical and economic faculties. Finally, the new trends in the social and political development of the Western countries in early 1970s becаme the significant factor in the decline of the protest movement, in particular the deterioration of the economic situation, as well as the expansion of the social elite at the expense of students and graduates of technical and economic faculties. This contributed to the further erosion of the social base of the protests and the focus of youth on their careers.

Nurturing undergraduate student leaders has become a priority in higher learning as it is beneficial for the students, institutions, employers, and society. Even though there are numerous initiatives for developing and educating student leaders, there is a need for fundamental studies on what student leaders perceive leadership to be, and the situations in which they would view it as crucial. The purpose of this article is to share the SWOT analysis report that was used to evaluate student leadership’s internal strengths and weaknesses, together with the external opportunities and threats. Structured open-ended survey questions were given to 78 student leaders during a leadership camp from a public university in Perak, Malaysia. Qualitative content analysis concept was used for the SWOT analysis. The core premise of a SWOT analysis based on the result must be taken into account for the leaders to better formulate a successful strategy, and for the planning of direction after carefully assessing the strengths, weaknesses, threats, and opportunities.

Malignant tumour cells secrete extracellular matrix (ECM) proteins with growth factors and cytokines to promote cell motility and adhesion for metastasis. The cell-ECM adhesion sites are comprised of integrin-bound ECM proteins, which are glycoconjugates, susceptible to the aberrant glycosylation resulting in alterations of cell-ECM adhesion dynamics. Inhibition of glycosylation could decrease the rate of invasiveness in metastatic tumour cells like osteosarcoma (OS), of which the underlying mechanism is still unknown. Hence, this study aims to determine the effect of glucosidase inhibitors towards the expression of ECM proteins in metastatic OS cell lines. OS cells (MG63) were treated with 0.5 mM of 1-deoxynojirimycin (1-DNJ). Analyses such as the glycosylation assay, ECM-cell adhesion assay, scratch assay, and Western blot analysis were performed after a 24-h treatment for each respective sample. The expression level of glycosylated proteins was the highest in non-treated MG63 cells. The cell migration rate was increased in MG63 cells treated with 1-DNJ compared to the normal osteoblast cells. The cell adhesion assay results showed an increased rate of cell adhesion towards vitronectin but decreased adhesion rate towards collagen (types I, II, and IV), fibronectin, laminin, and tenascin in 1-DNJ-treated OS cells. Western blot analysis presented a high expression level of fibronectin, vitronectin, and collagen type II in both non-treated and treated groups of MG63 cells. The inhibitory effect of 1-DNJ upregulates ECM remodelling by disrupting integrin from binding to the ECM proteins, subsequently increasing the migration rate of metastatic OS cells.

Political Disputes in the Structure of A. Solzhenitsyn’s novel “In the First Circle”
Authors:   Lomonosov Moscow State University, Nichiporov Ilia
Published: February 2024

The article is devoted to the analysis of socio-political discussions in A. Solzhenitsyn’s novel “In the First Circle”. The “playwriting” of dialogues and polylogues on political topics has received an original compositional embodiment here and is based on the mobile, acutely conflicting interaction of various speech flows. Political disputes acquire a moral and philosophical dimension in the work, push the interlocutors to historical assessments and prophecies about the future social structure. Episodes of situational mass disputes are combined with individualized, lengthy and conceptually rich discussions, which often have their own compositional preliminaries and “afterwords”. The article examines in detail the substantive and rhetorical aspects of conversations and clashes involving Rubin, Nerzhin, Sologdin, Gerasimovich, pays attention to uncle Avenir’s political strategies, internal disputes, the evolution of Volodin’s social views, the positions of Galakhov, Radovich, Clara Makarygina. Paradoxically, it is the prisoners’ disputes that show in the novel the highest level of moral, intellectual, and political freedom, unthinkable for the social climate of the Stalinist decades. In the structure of the novel, explicit political battles and hidden, forcibly suppressed social differences form a holistic, branched macro-plot in which, despite the pressure of the totalitarian system, individual and collective social reflection continues to pulsate.
The Role of the Debates on the Definition of the Italian Oral Language and on the Means of Its Propagation after the Italian State Declaration
Authors:   Patrice Lumumba Peoples’ Friendship University of Russia, Loreti Angelo
Published: February 2024

The article examines the role of debates on the definition of a national oral language in Italy, where the divergence between the written, literary language and oral dialects has historically been very significant. The decisive contribution to the definition of the oral language, by choosing the Florentine language as the model of the oral Italian language was made by Alessandro Manzoni along with Graziadio Isaiah Ascoli, who suggested that the adoption of the Florentine language would lead to a formal cult of “popular purity” instead of the ideal of “classical purity”, and that the linguistic would be the result of a deeper action with the aim of spreading culture and bridging the gap, separating a small circle of intellectuals from the rest of the population. In conclusion, the author considers that the convergence of written and spoken Italian has led to the fact that, today, the proficiency in written language among Italians is lower than the average in European countries, and Italians still perceive the spoken language as an unnatural language.

El espacio interior contemporáneo conforma el tema general que planteo en esta exposición. En un principio, el interés por este tipo de escenarios era puramente visual. Me atraían por su complejidad formal, sus elementos repetitivos, su dureza angular, sus geometrías evidentes, que cuadriculan la imagen en la materia. A su vez, conforman un motivo válido con el cual jugar con los valores que conforman el plano pictórico, como la luz, el color, el ritmo o la composición. En definitiva, una excusa que me permite plantearme problemas plásticos y organizar todos los recursos del lenguaje pictórico.

El juego de palabras contenido en el título de esta exposición, Heart-Self (Corazón-propio), es de difícil traducción, apunta al conjunto léxico Help-Self (auto-ayuda), aunque a la par resuenan en él otras figuras de inestable semántica. El deseo-de-nombrar la distancia que le separa del mundo, y por ende de su propio cuerpo, se complica cuando lo que Beatriz Ros quiere nombrar es lo que falta, lo que no está presente, lo que quedó atrás o aún no ha llegado, dicho de otro modo, aquello que se resiste a ser representado y que la artista resuelve excelentemente con una poética que bascula entre liberación y condena, entre el pellizco en el corazón y la placentera huída.

Authors: Khater Jacinthe , Malakouti Sara , Khoury Antoine El , Cortese Bernardo
Published: February 2024

Aims

The use of sodium-glucose cotransporter 2 inhibitors (SGLT2i) as a new class of drug in treating type 2 diabetes has expanded beyond its original framework. Positive results have been achieved in reducing symptoms in patients with cardiovascular disease (CVD). The aim of this article is to present an in-depth review of the basic principles of this class of medications and how it has brought benefits to patients affected particularly by heart failure.

Methods

Following a thorough PubMed search, this review includes 62 studies published between 2015 and 2023. Keywords searched included ‘sodium-glucose cotransporter 2 inhibitors’, ‘cardiovascular disease’, ‘heart failure’, ‘chronic kidney disease’, and ‘type 2 diabetes’. The most recent and comprehensive data were used.

Results

Positive results have been achieved in reducing symptoms in patients with CVD. SGLT2 inhibitors have also been shown to be useful in other contexts such as nonalcoholic fatty liver disease (NAFLD) by reducing liver fat accumulation, kidney benefits by improving body weight and vascular endothelium, improving eGFR, and reducing progression to end stage kidney disease (ESKD). SGLT2 inhibitors are also effective in reducing the need for heart failure hospitalizations and the risk of serious cardiac adverse events, including cardiovascular and all-cause mortality, in patients with reduced or preserved left ventricular (LV) ejection fraction and in acute or decompensated settings.

Conclusion

SGLT2 inhibitors have evolved into metabolic drugs because of their multisystem action and are indicated for the treatment of all spectrums of heart failure, type 2 diabetes, and chronic kidney disease.
Is mother tongue instruction culturally empowering?
Authors: Mannish Scarlett
Published: February 2024

In this paper, I formulate a position on the dissemination of ‘cultural empowerment’ in schools through a critical discussion of its relation to my research field, mother tongue instruction (MTI) in Sweden. In addition, I compare the ideals of the culturally empowering pedagogies and praxis of MTI, which I see as related through the underlying utopian visions of the multilingual and multicultural school. Both are forms of education which place a focus on the validity and importance of students’ individuality and their pre-existing knowledges from outside the curriculum. In discussing the marginalisation of MTI via the discourse of its threat to ‘Swedishness’, I hope to highlight some of the underlying problems inherent in cultural empowerment as an individualising practice carried out within the universalising framework that is the state education project. The implementation of MTI demonstrates a need for change targeted not only at the level of teachers and researchers but also at a level where legitimacy is granted to such change.
Power, discourse, and student agency in colonial education
Authors: Ayele Tesfaye Woubshet
Published: February 2024

This paper aims to glean valuable insights from critical pedagogy in order to apply them to the field of African literary studies. Specifically, I am interested in how approaches inspired by culturally responsive education can help us revisit the important but under-researched topic of student agency as it features in fictional works that deal with colonial education in Africa. Although colonial education in literature has been the subject of intense focus in postcolonial theory, such theorizations largely examine how colonial education reproduces colonial rule through the dissemination of colonial discourse/ideology. When student agency in the colonial education systems is addressed, conventional postcolonial theory sees it as being overwhelmed or assimilated by colonial discourse and power. Ideas emanating from critical pedagogy and culturally responsive education are of value here in that they can elucidate how students interact with and even resist the pedagogical and political power of the colonial education system. Ngũgĩ wa Thiong’o’s novel Weep Not, Child is an illustrative example of how such a critical-pedagogy-inspired approach can help us reorient literary studies of colonial education systems.
Responsiveness to culture through literature
Authors: Brauer Alexander
Published: February 2024

This position paper argues that creative writing can be a fruitful tool for cultural responsiveness in secondary education and calls for creative writing to be viewed as a more natural part of language teachers’ culturally responsive pedagogical repertoire. The integration of creative writing exercises in culturally responsive language arts education may rouse a strengthened voice, benefit cultural literacy, engender the discovery and exploration of individual funds of knowledge, enhance relational competence, and bring about the critical crafting of and engagement with cultural representations. These arguments are convergent with the view that teaching, in order to be culturally responsive, should originate from students’ funds of knowledge, taking both subject content and relational aspects into consideration – and this paper proposes that creative writing is uniquely positioned to facilitate these aims.

Published: February 2024

With the toll road, people's mobility becomes easier. The large number of people using toll roads makes the number of vehicles increase. This often causes congestion that occurs when approaching the toll booth, this congestion occurs because the capacity of vehicles arriving exceeds the service capacity of the toll gate. MLFF is a technology that allows toll road drivers to pay without stopping at toll booths. This study aims to find out the public's perception if the toll payment system changes to the MLFF payment system and the success of MLFF if implemented on the Jabodetabek toll road. The research was compiled using literature studies and quantitative methods and data collection was carried out by distributing questionnaires to Jabodetabek toll road users. The results of the analysis show that the majority of toll road users agree if MLFF is implemented on Jabodetabek Toll Roads and agree on the opinion that implementing MLFF can reduce congestion that occurs when approaching the toll gate. However, the transition process will require good socialization from the government and public acceptance of this new payment system.

 

Dengan adanya jalan tol mobilitas masyarakat menjadi semakin mudah. Banyaknya masyarakat yang menggunakan jalan tol membuat jumlah kendaraan yang melalui jalan tol semakin banyak. Hal ini sering menyebabkan kemacetan yang terjadi ketika mendekati pintu tol, kemacetan ini terjadi karena kapasitas kendaraan yang datang melebihi kapasitas pelayanan pintu tol. MLFF merupakan suatu teknologi yang memungkinkan pengendara jalan tol membayar tanpa berhenti di pintu tol. Penelitian ini, bertujuan untuk mengetahui persepsi masyarakat apabila sistem pembayaran tol berubah menjadi sistem pembayaran MLFF dan keberhasilan MLFF jika diterapkan di tol Jabodetabek. Penelitian disusun dengan menggunakan studi literatur dan metode kuantitatif dan perolehan data dilakukan dengan penyebaran kuesioner kepada pengguna jalan tol Jabodetabek. Hasil analisis menunjukkan bahwa mayoritas pengguna jalan tol setuju apabila MLFF diterapkan di Tol Jabodetabek dan berpendapat bahwa dengan diterapkannya MLFF dapat mengurangi kemacetan yang terjadi saat mendekati pintu tol. Namun untuk proses peralihan akan diperlukan sosialisasi yang baik dari pemerintah dan penerimaan masyarakat akan sistem pembayaran baru ini.

Authors: Xavieri Linggo Johannes Christophorus , Sutandi Arianti
Published: February 2024

The concept of green building is one way to address global warming. In Indonesia, the number of buildings implementing green building concepts is still very limited. The government has implemented several regulations related to green building concepts, but there are still challenges such as lack of information, inadequate financial incentives, and awareness programs by the government and other relevant authorities. This study aims to identify the barriers faced in the implementation of green building in Indonesia, specifically in DKI Jakarta, to determine the underlying constraints in the development of green building in the country. Questionnaires for this research were distributed to consultants and developers in Jakarta. The research findings indicate that there are six factors constraining green building implementation, namely regulation, government, finance, technical, technology, and education.

Concrete is one of the most important materials used in building structures. A material that can be used to create normal concrete with this method is to add palm shell ash to the concrete mix. Palm shell ash can be used as a filler material, because the ash has a chemical composition contains silica (SiO2) which is amorphus and highly reactive at room temperature. The use of palm shell ash as an additive to the concrete mixture aims to improve the quality of the concrete which is planned after palm shell ash is added to the concrete mixture. The tests carried out in this study were compressive power, split tensile power, flexural power, and modulus of elasticity at the age of 28 days concrete. The number of samples made was 36 cylinders and 12 blocks for variations in percentage of 0%, 5%, 10%, 15%, 20% and 25%. The treatment of the specimens was done by immersing them for 26 days. The values of compressive power, split tensile power, flexural power, and elastic modulus will decrease when the percentage of palm shell ash in the concrete mixture increases.

Beton merupakan suatu material yang begitu vital untuk diaplikasikan dalam dunia konstruksi. Suatu materi yang bisa dimanfaatkan untuk menciptakan beton normal dengan metode ini adalah dengan menambahkan abu cangkang sawit ke dalam campuran beton. Abu cangkang sawit bisa dimanfaatkan selaku materi pengisi (filler), sebab abu tersebut memiliki kompenen kimia yang mengandung silika (SiO2) yang bersifat amorphus (bukan kristal) dan sangat reaktif pada temperature kamar. Penggunaan abu cangkang sawit selaku materi tambahan dalam campuran beton bertujuan untuk meningkatkan mutu beton yang direncanakan setelah abu cangkang sawit ditambahkan pada campuran beton. Percobaan yang diselenggarakan pada penelitian berikut adalah kuat tekan, kuat tarik belah, kuat lentur, dan modulus elastisitas terhadap usia beton 28 hari. Jumlah sampel yang dibuat adalah 36 buah berbentuk silinder dan 12 buah berbentuk balok dengan variasi persentase sebesar 0%, 5%, 10%, 15%, 20%, dan 25%. Perawatan materi pengujian dilakukan dengan upaya direndam dalam 26 hari. Hasil kuat tekan, kuat tarik belah, kuat lentur, dan modulus elastisitas menurun ketika persentase abu cangkang sawit pada campuran beton meningkat.

Toll roads are one of the important priorities for the country because toll roads can facilitate the community in supporting the economic growth of an area. Toll roads facilitate accessibility, causing a high level of interaction between regions. This ease of accessibility is felt by small and medium businesses. Small and medium businesses help the growth of Gross Domestic Product (GDP). Toll roads can also have a negative impact on small and medium businesses in a region. This research wants to look at the objective aspect of the project life cycle of a construction plan based on the Project Management Body of Knowledge. Civil engineers are expected to not only focus on the construction phase but also look at aspects that exist in a project life cycle. This study is to determine the economic characteristics influenced by toll road infrastructure development and analyze the characteristics of small and medium businesses. The data used in this research is questionnaire data. Questionnaire data will be processed using a statistical program with validity test, reliability test, and factor analysis. From the output obtained, the factors formed will be based on existing variables, namely X1.5, X2.1, and X3.2.

Foundation is one of the most important structural components in a high rise building which has a function to stabilize a building so that it can stand firmly to withstand the weight of the building above it. In its construction, the foundation must be designed optimally both in terms of planning, design, implementation methods to the budgetary costs of the foundation. In this study, we will compare the most effective foundations in terms of strength and price. This can be known by designing the depth of the foundation based on the existing soil parameters, the width of the foundation, and the method of implementation. The foundations to be studied are foundations with a width of 500, 600, 1000, 1200, dan 1500 mm. The plan depths are 25 m, 33 m and 40 m. While the distance between the piles is 2,5D and 3D. It was found that group pile foundations had the most optimum design based on the value of the resulting bearing capacity to the volume of concrete for the entire group pile foundation, which has a diameter of 500 mm, 33m depth of the group piles, and distance between piles 2,5D, and has 631 piles in total.

Fondasi merupakan salah satu komponen struktur penting yang ada pada gedung bertingkat yang berfungsi untuk menjaga kestabilan suatu gedung agar dapat berdiri kokoh menahan beban gedung yang ada di atasnya. Dalam pembangunannya, fondasi harus dirancang dengan maksimal baik dari segi perencanaan, perancangan, metode pelaksanaan hingga biaya anggaran dari fondasi. Pada penelitian ini, akan dibandingkan fondasi yang paling efektif dari segi kekuatan dan harga yang dilihat berdasarkan kubikasi. Hal ini dapat diketahui dengan perancangan kedalaman fondasi berdasarkan parameter tanah yang ada, lebar fondasi, dan metode pelaksanaan. Direncanakan fondasi yang akan diteliti berupa fondasi tiang bor dengan diameter 500, 600, 1000, 1200, dan 1500 mm. Untuk kedalaman rencananya adalah 25 m, 33 m, dan 40 m. Sedangkan jarak antar tiangnya adalah 2,5D dan 3D. Setelah melakukan perhitungan dan analisis melalui berbagai metode, didapatkan fondasi tiang kelompok yang memiliki desain paling optimum berdasarkan besarnya daya dukung yang dihasilkan terhadap banyaknya kubikasi beton untuk keseluruhan fondasi tiang kelompok yaitu tiang kelompok dengan diameter 500 mm, kedalaman tiang kelompok 33m, dan jarak antar tiang 2,5D, serta memiliki 631 tiang.
