International Law: Existence in International Dispute Settlement Efforts as a Symbol of Peace in the International Community
Authors: Firdaus F M Waritsul , Mardiah Radiyatam
Published: August 2023

The settlement of disputes has been a significant concern in the international community since the 20th century. In its early development, dispute resolution could be achieved either peacefully or through the use of force. However, with the growing awareness of the dangers of war and the advancement of weapon technology, the international community has increasingly recognized the importance of peaceful dispute resolution. In the dynamics of its development, international dispute resolution can be distinguished between legal and political disputes. The opinions of international law experts regarding this distinction vary. There is also a middle ground view that states every dispute has its own political and legal aspects. The development of peaceful dispute resolution has been taking place since the Hague Peace Conferences of 1899 and 1907. During these conferences, rules for peaceful dispute resolution between nations were established. International law also regulates the obligations of states to settle disputes peacefully, as stated in the UN Charter. Technological advancements and the existence of official rules from the UN have strengthened the presence of international law in maintaining international peace and security. The obligation of states to settle disputes peacefully and refrain from the use of force is a recognized principle in international law.

One of the prominent challenges of social enterprises is the inability to sustain their performance. In recent years, there have been instances where social enterprises have faced issues related to mismanagement, and these incidents have been associated with lack of effective governance. Therefore, this qualitative study engaged semi-structured interviews with representatives of social enterprises in Malaysia in assessing and examining the ideal governance framework that would suit the needs of social enterprise to attain sustainable performance. At first glance, the findings suggest that governance is achieved through effective control mechanisms and accountability practices. However, the respondents had also shared some insights that would suggest a forward-looking approach to social enterprise governance that prioritises sustainability, innovation, and social impact, rather than just control and compliance. Additionally, another substance being highlighted by the respondents that is closely related with social enterprise governance is about building relationships and trust.

"This paper focuses on the musical analysis of Veress’s orchestral composition, Threnos. Written in 1945 and dedicated to the memory of Bartók, it is a one-movement work, divided into three independent internal sections, each of them representing an orchestral gradation. Being a threnody, Veress inserts two folk-like funeral laments, which are the composer’s melodic inventions, in the style of folk music. Veress, the ethnomusicologist and composer presents the bartókian principle of how to capture the ethos of folk music in its structure, melody, harmony, and rhythm, and how to express it in such a modern and innovative way, that a completely new quality is born from it.

"The purpose of this article is to compare the neurophysiological processes of the brain during vocal improvisation and the psychological implications of a spontaneous composition of melody. By taking command of the present, while at the same time bringing forward to the audience an extensive amount of musical knowledge and specific vocal techniques, vocal improvisation is an extensive field of interest for jazz singers and jazz voice educators alike, and its distinct processes are yet to be fully understood and explained. In my years of studying and practicing vocal improvisation, I have sought to understand the balance between these two components – the cognitive and the psychological coordinates of the vocal improvisation and the implications of these coordinates on our everyday life, outside the performing arts frame. The reasons why a singer makes certain musical choices when creating spontaneously, while avoiding others, together with the reasons why improvisation is important in our everyday lives, these reasons make the object of this study. Keywords: vocal improvisation, spontaneous creation, psychological process"

"This research presents a medieval musical manuscript that has not yet been analyzed in detail. Catalogued under the name of Graduale Latino-Bohemicum, and currently held in the Batthyaneum Library of Alba Iulia, it has many peculiarities in comparison with other similar codices from the Transylvanian area, hence also compared with other Czech manuscripts. We offer analysis around the date of its creation, then debate different naming options. To create the proper context of understanding for the analysis, we present a brief historical background of the time and place in question, that is the turbulent 15th and 16th century of Europe, with special focus on Transylvania. We continue with the physical aspects of the manuscript that guide us through the colorful world of medieval codices. From a structural standpoint the work has two delimited parts. The bilingual manuscript starts with chants written in Czech and finishes with melodies in Latin. The existence of the Czech language, as well as many other clues govern us to set up hypotheses regarding its provenance. During the content analysis we dedicate a subchapter to the later page inserts that contain additional notes for the chants, wherefrom we can further conclude theories about the usage of the codex, authors of the later annotations, and so forth. We offer a more in-depth analysis of the musical notation where aspects like rhythm, staff, neumes used and special solutions are shown. Finally, we conclude all major, raised questions related to the name, origin, and genre.

"The article is devoted to a variant method of composing music, which became widespread in the composing practice of the twentieth century and has genetic links with the work of Franz Liszt. The variant method is presented as the basis of the composer’s artistic system, as a property of musical logic and form formation. During the functional and structural analysis of the songs of F. Liszt, their typological similarity is revealed, and a classification based on the variant principle of thematic development is proposed. The characteristic of variant-strophic (“An Edlitam” (S. 333; LW. 74)) and variant-phase (“Gebet” (S. 331; LW. №72)) forms is given. The relationship between monothematism and the variant method of composition is revealed. As a result, the genetic connection between the vocal miniature of F. Liszt and the musical art of the 20th century is substantiated. The variant method is presented as a system-forming method at all levels of musical and poetic composition (motif-composition-image-drama-way of thinking). Keywords: variant method, variant form, vocal creativity, composition, the principle of thematic development."

Interferences Between Tradition and Modernity in the Symphonic and Concerto Works by Adrian Pop – (1) The Cello Concerto

"The present study marks the beginning of a series of analytical undertakings focused on the symphonic and concerto works by the Cluj composer Adrian Pop. Following the pieces’ chronological line and keeping as a reference their common source of inspiration – the Romanian folklore – the conclusions aim to reveal the way in which the author’s individuality relates to the tendencies of contemporary language, as well as the European music tradition, without overshadowing our autochthonous stylistic matrix. Starting from a carol taken from Sabin Drăgoi’s collection of 303 Carols, the discourse of the Cello concerto provides a masterly example of how the variational technique is applied in the processing and development of microstructural elements, whose archaic essence is preserved and amplified both at the moment of the explicit exposure of the original melody in the second part (following its „genesis” throughout the first part), and during the effervescent unfolding of the final movement. Keywords: folklore, carol, variation, development, tradition, modernity"

El sentimiento divino: la función epistémica del deseo erótico en la teoría de la reminiscencia de Platón
Authors: Candiotto Laura
Published: August 2023

En los "diálogos eróticos", especialmente el Simposio y el Fedro, Platón explicó por qué el deseo erótico puede desempeñar una función epistémica, estableciendo una fuerte conexión entre el deseo erótico y la belleza, "la más claramente visible y la más amada" (Fedro 250e1) entre las Ideas. Tomando los diálogos eróticos como trasfondo, esclareceré en este trabajo la explicación de Platón en otro contexto, el del Fedón (72e3-77a5), para discutir la función epistémica del deseo erótico en relación con el argumento de la deficiencia y el argumento de la afinidad. Mi propuesta es que el deseo erótico del filósofo se activa al reconocer vestigios de las Ideas, algo de lo que carece el mundo material, y con lo que, sin embargo, su alma está familiarizada. Este deseo de las Ideas desencadena el proceso de la reminiscencia, y así el deseo erótico adquiere un papel decisivo en la adquisición del conocimiento en el Fedón. En la sección final del trabajo, remarco la relevancia contemporánea de la epistemología platónica acerca del deseo erótico.
Plotino y las emociones del Pórtico
Authors: Zamora Calvo José María
Published: August 2023

En este artículo exploramos la integración de la teoría plotiniana de las emociones a partir de la rehabilitación del órgano sensorial. Desde esta perspectiva, el alma es perturbada por la abundancia de sensaciones y las emociones son consideradas actividades del alma, que se experimentan cuando esta se da cuenta de los estados del cuerpo. Pero, al igual que en el caso de la sensación, el alma no se ve afectada por las emociones del cuerpo. Para vivir de manera virtuosa el alma conoce de qué manera ha de domeñar los afectos irracionales provenientes del cuerpo, ejerciendo el nivel intelectivo del alma un control total de las emociones.

Scholarships play a crucial role in providing financial assistance to students and enabling them to pursue quality education. However, the existing manual processes and fragmented information systems often lead to challenges in accessing scholarship details and timely dissemination of information. The proposed system addresses these challenges by leveraging web-based technologies and designing an integrated platform for efficient scholarship management. The system incorporates features such as a centralized database, user-friendly interface, and robust search functionality to enable seamless access to scholarship information. By adopting a web-based approach, the system ensures accessibility from various devices, including desktop computers, laptops, and mobile devices. Moreover, the system emphasizes the importance of fast information dissemination. It enables real-time updates and notifications to keep students, scholarship providers, and other stakeholders informed about application deadlines, eligibility criteria, and any changes in the scholarship programs. Additionally, the system allows for personalized notifications, ensuring that users receive relevant updates based on their preferences and areas of interest. The design of the web-based information system prioritizes security and privacy by implementing stringent authentication mechanisms and encrypted data transmission. It also incorporates features for efficient application submission, document management, and evaluation processes, streamlining the entire scholarship lifecycle. The expected benefits of implementing this system include improved accessibility to scholarship opportunities, reduced administrative overhead, increased transparency in the selection process, and enhanced collaboration among scholarship providers and educational institutions. By leveraging the power of web technologies, the proposed system aims to revolutionize the management of scholarships, ultimately promoting equal educational opportunities and fostering academic excellence.
