Newell Ann Van Auken: Spring and Autumn Historiography: Form and Hierarchy in Ancient Chinese Annals
Authors: Shaughnessy Edward L.
Published: January 2025

Over the last fifteen years, Newell Ann Van Auken has established herself as the Western world’s foremost authority on the Chunqiu 春秋 (Spring and Autumn), one of China’s traditional five classics. More than that, she is one of the only authorities on the text, or even one of the very few people who has ever read it, at least as an integral text. Most readers encounter it in the course of reading the more entertaining Zuo zhuan 左傳 (Zuo Tradition), or perhaps the Gongyang zhuan 公羊傳 (Gongyang Tradition) or Guliang zhuan 穀梁傳 (Guliang Tradition), its three authoritative commentaries. Van Auken has read the text itself very carefully indeed, so carefully that she has been able to discern formal properties that have escaped even the finest traditional Chinese readers. In her most recent book, Spring and Autumn Historiography: Form and Hierarchy in Ancient Chinese Annals, the sub-title of which is particularly informative, she explores five different aspects of the formal properties of the text to argue that the Spring and Autumn was a conscious attempt to elevate the status of the state of Lu 魯, the state of which it is an annalistic history.
Ife and Bilal: Reflections on an Afro-Asian intercultural, practice-based intervention
Authors: Stacey Cara , Aranha Mark , Clacherty Bronwen , Stone Kristy
Published: January 2025

This article reflects on an artistic production created between 2017 and 2018 as part of a Mellonfunded, inter-institutional research  project titled: ‘Re-centring AfroAsia: Musical and human migrations in the pre-colonial period 700-1500 AD’ (University of Cape Town,  University of the Western Cape, University of the Witwatersrand, Ambedkar University Delhi). The production, titled Ife and Bilal, was an  intercultural and interdisciplinary collaboration between artists from South Africa, India, and Turkey. As an exploration in grounding  contemporary creative and scholarly inquiries outside of Eurocentric discourse, it explored ancient oceanic connections through a live, improvised performance of sound and visuals. In the interconnected world of the Indian Ocean a thousand years ago, water was the  conduit that carried people, ideas, and sounds between Africa and Asia. The story of Ife and Bilal revisited that world, where journeys  were unpredictable and at the mercy of the forces of nature. Knowledge, collaboration and improvisation were key to survival. The theatrical production embraced these elements, moving away from the literal and towards themes from the littoral, using historically  informed media in experimental ways to convey a narrative. Resisting nostalgic or stereotypical representations of a past, the authors  drew inspiration from tenth-century Arabic, African and other contemporaneous enquiries into astronomy, astrology, optics, geometry  and alchemy. The performed and projected visual art elements explored the material aspects of water, sound, metal and light. Here,  science and art worked together with music to locate unseen currents within these historical moments and narratives of fate and fortune.  In this article, we reflect on the experimental process of creating Ife and Bilal as artist-researchers, situating our practise within  a broader decolonial epistemological project.
Lecturers’ Views on Teaching Composition at South African Universities: A Qualitative Enquiry
Authors: De Villiers Frelét , Palmer Chesney
Published: January 2025

The pedagogy of composition plays a vital role in developing up-and-coming new composers who are trying to find their own voice. The  aim of this study was to explore the views of lecturers at South African universities on teaching composition. Many academic outputs  have been published on aspects of composition techniques and skills; however, there is a paucity of sources that deal with teaching  composition at higher-level institutions. A qualitative study was conducted in which data were collected by means of conducting semi- structured interviews, using open-ended questions, with six composition lecturers at South African universities. The main findings are  that lecturers teach composition based on their backgrounds and experience gained during their careers without imposing their ideas on  their students. They strive to provide students with the necessary skillset and compositional techniques. It is considered vital to  include theoretical underpinnings, analysis and aural training in the composition module in order to nurture the student towards  maturity in their composition styles. This study may help lecturers of composition to understand the nature of composition pedagogy  and the essentials of the interaction that should ideally take place between student and lecturer.
Gideon Fagan’s Late Style: the Suite for Strings (1974)
Authors: Lüdemann Winfried
Published: January 2025

Gideon Fagan’s (1904-80) position in South African music history has not yet been thoroughly established despite his illustrious career as  a conductor, music administrator, teacher and composer. This is a remarkable gap in South African music scholarship. The present article  is an attempt to highlight Fagan’s importance specifically as a composer by discussing his compositional output from the perspective of  its possible division into three creative periods and by examining a representative work from the last of these periods, the Suite for  Strings (1974). Besides offering penetrating analyses of the six movements of this work, the article poses the question whether the Suite  – together with other works from Fagan’s last creative period – can be approached from the perspective of what has become known in  music, art and literature scholarship as ‘late style’. These considerations are contextualised by discussing the tradition of writing  biographical studies on important artists, and against the backdrop of investigations into the phenomenon of late style by Theodor W.  Adorno, Carl Dahlhaus, Edward Said, Nikolaus Urbanek, Gordon McMullan, Sam Smiles, Michael Spitzer and Robert Spencer.
The Theory of Musical Forces: Filling Some Gaps with Integrations and Expansions
Authors: Meyer Jaco
Published: January 2025

Since Steve Larson published the first writings on his theory of musical forces in 1992, many of the aspects, terms and definitions that he  introduced were developed, expanded upon and improved by himself and other researchers. Larson wanted to expand on his own work  and write a sequel to his book Musical Forces: Motion, Metaphor, and Meaning. However, he passed away in 2011, shortly before the  publication of his first book on musical forces. His intention to write a sequel shows Larson's awareness of the incomplete state of his  theory and of the opportunities the theory offers for expansion. Several theorists expanded Larson's theory, the most important being  Robert Hatten. Through my own work on expanding the theory of musical forces, I discovered certain perspectives and terminologies  that invite further exploration and clarification, as is the case with developing theories. Clarification of these ambiguities and an  integration of Hatten’s work into the theory are indispensable for further work within the theory of musical forces. The aim of this article  is to identify potential gaps in the theoretical framework, as well as potential areas for further investigation and clarification. I aim to fill  some of these gaps for prospective researchers so that it will not be necessary for them to work on fundamental aspects of Larson's  theory. Some of the issues in this article are speculative, similar to Larson’s work on this developing theory, and will need further  research and refinement. I hope that the work presented in this article will enable other researchers to apply and further expand the  theory. Although some of the parts in this article is an expansion of Larson’s work, the aim here is not to offer full expansions of  particular aspects, but rather to contextualise and partly elucidate existing expansions.
Post/koloniale Verstrickungen. Der Fall Renzo Martens und die Grenzen der Kunstwissenschaft
Authors: Peyer Siri
Published: January 2025

Das 2012 vom Künstler Renzo Martens in der Demokratischen Republik Kongo gegründete Institute for Human Activities (IHA) ist höchst umstritten: Sehen die einen darin einen zynischen und selbstgerechten Kommentar des Künstlers zu den Mechanismen von kritischer Kunst auf dem Rücken der kongolesischen Mitstreiter:innen, loben die anderen dessen Anbindung an reale Lebenswelten als präzise Kritik an den Ökonomien des westlichen Kunstbetriebs. Kunstkritik und Kunstgeschichte kommen angesichts dieser ambivalenten und komplexen Konstellationen an ihre Grenzen, neigen zu thematischen Zuspitzungen oder einengende Kategorisierungen.

Die Publikation untersucht, wie diese werkimmanenten Widersprüche so in eine Analyse aufgenommen werden können, dass sie nicht in vereindeutigenden Positionierungen aufgelöst werden. »Post/koloniale Verstrickungen« entwirft dabei eine transdisziplinäre Methodologie, die Renzo Martens’ IHA ‹von der Kunst aus denkend› analysiert. Dabei wird das Projekt nicht über eine theoretische Perspektive erschlossen, sondern das Kunstwerk zum Gegenüber erklärt, von dem aus die Fragen erst entwickelt werden.

Transformation Management of the Monetary Policy Transmission from the Exchange Rate Channel to the Interest Rate Channel in Iraq 2004-2020
Authors: Qasim Bilal , Smida Mounir
Published: January 2025

Objectives: The study aims to examine the Transmission Mechanism (MPT) through the interest rate channel in Iraq and its impact on the macroeconomy, focusing on the monetary authority's tools used to influence macroeconomic variables. It also analyzes actions taken to reduce the inflation gap and output gap.
 
Methods: The study used path analysis to measure the direct and indirect effects of the Monetary Policy Transmission Mechanism (MPT) through the interest rate and saving & investment channels, with GDP as the representation of the real economy.
 
Results: The study found that the interest rate channel in Iraq's economy is weak. Despite efforts by the monetary authority to control inflation and manage the money supply, the distorted economic structure and ineffective tools, including the interest rate, limit the overall effectiveness of monetary policy.
 
Conclusion: The study concluded that the interest rate channel needs to be activated and strengthened. A proposed scenario suggests utilizing the capabilities of the Central Bank and its tools, such as the project financing initiative and rediscounting of securities, to improve the effectiveness of monetary policy and credit channels in Iraq.
Demonetization is a Curse or Blessing: a Study in the Context of Real Estate Market in Pune City
Authors: Koner Jonardan , Purandare Avinash
Published: January 2025

Objectives: The study aims to measure the impact of demonetization on both residential and commercial real estate units, focusing on the primary and secondary real estate markets.
 
Methods: The study used a multiple regression analysis model to assess the impact of demonetization on the real estate sector.
 
Results: Demonetization had a significant negative short-term impact on the real estate sector, leading to a fall in demand in all segments of the primary and secondary markets, both residential and commercial. The primary reason for this decline was the reliance on cash transactions in real estate financial dealings. However, the increased deposits from demonetization enhanced the liquidity position of banks, which can be leveraged for credit to boost the real estate sector in the long term.
 
Conclusion: Demonetization is expected to have a positive long-term impact on the real estate sector, as the increased transparency and accountability will attract institutional investors and foreign direct investment, thereby improving the sector's growth.

Authors: Wangi Putri Sekar , Triase Triase
Published: January 2025

Along with the rapid development of information technology, the world of education is also developing towards the digitalization era. Therefore, the use of information technology is needed to support the progress of the world of education. At SMA Negeri 6 Pematangsiantar, students who receive counseling guidance are students who do not obey school regulations such as undisciplined behavior in learning activities and extracurricular activities. According to psychologists, there is a relationship between negative behavior and the level of stress experienced by children. Signs that a child is experiencing stress include anger, aggressive behavior, and disobedience. It could be concluded that one of the triggers for negative behavior in children at school can be caused by stress. This study was conducted to determine the effect of student stress on their academic grades. By applying Data Mining using K-Means Clustering Algorithm, students can be grouped based on stress levels and academic achievement. So that a potential relationship can be found between these variables. In addition, the use of a counseling information system can improve the implementation of counseling to be more effective and efficient. Based on the research results, by collecting 960 student samples that will be used as calculation samples, the value of cluster one (C1) is at the average academic value (sufficient) with a moderate stress level percentage and cluster two (C2) at the average academic value (good) with a low stress level percentage. So it can be concluded that the percentage of stress experienced can affect their academic value.

Energy Utilisation and Household Consumption in Rivers State
Authors: Ewubare Dennis Brown , Osuji Ifeoma
Published: January 2025

In this study, the link between energy utilisation and household consumption was examined. The energy utilization comprised both solid and non-solid fuels such as electricity, liquified petroleum gas (LPG), premium motor spirit (PMS), kerosene and charcoal. A well-structured questionnaire was used to obtain the required primary data from a sample of 384 households across the three senatorial zones in Rivers State. The data analyses integrate both descriptive and inferential statistics with a focus on frequency counts, simple percentages, mean ratings and ordered logit regression analysis. The distribution of the households based on their consumption level showed that 132 (34.38%), 124 (32.29%) and 128 (33.33%) of the respondents in the survey reported fair, good and excellent consumption respectively, indicating that the majority of them experience fair consumption. The marginal effects results of ordered logit regression showed that electricity use significantly increases the probability of reporting better consumption (from fair, good to excellent) by 0.582%. Similarly, the results showed that LPG utilization increases the probability of reporting better consumption by 1.97%. This finding highlights the importance of access to clean energy on household consumption. In addition, the results showed that the use of charcoal significantly increases the probability of reporting better consumption by 0.125% while PMS utilization significantly decreases the probability of reporting better consumption (from fair, good to excellent) by 0.164%. Given the findings, this study recommends that government should prioritise a stable electricity supply by investing in infrastructure upgrades and build synergy with the private sector to improve LPG supply to enhance availability and affordability of energy for better household consumption.
Revisión de alcance sobre el “derecho personalizado”, la evolución de la precisión de las normas en el derecho actual
Authors: Lombardi Llanos María José Antonella
Published: January 2025

La proliferación de dispositivos del Internet de las Cosas (IoT) ha generado grandes cantidades de “Big Data”, permitiendo la predicción de comportamientos futuros mediante el análisis de patrones. Esto ha llevado al concepto de Derecho Personalizado, que busca adaptar las regulaciones de manera precisa a casos individuales, evitando generalizaciones injustas. El desarrollo de algoritmos e inteligencia artificial ha expandido este concepto, introduciendo discusiones sobre regulación basada en algoritmos en diversas áreas del derecho. Este enfoque ha dado lugar al concepto de “normas jurídicas granulares”, una técnica regulatoria personalizada explorada principalmente en el Derecho Privado. Este estudio analiza la viabilidad y aplicabilidad de la regulación jurídica basada en algoritmos en diferentes ramas del derecho. Se realizó una revisión de alcance utilizando ScienceDirect, SCOPUS y bases de datos web para identificar artículos que abordan las normas granulares en el derecho. La revisión identificó 138 artículos centrados en ciencias sociales y derecho personalizado, publicados entre 2014 y 2024. Los resultados destacan el enfoque novedoso del Derecho Personalizado en la adaptación de regulaciones a necesidades y atributos individuales. El estudio concluye que las normas granulares ofrecen mayor eficacia debido a su “particularidad”, aplicándose a casos específicos y adaptándose a las necesidades individuales, generando así una regulación más efectiva, especialmente en la protección del consumidor.

Authors: Vuong Xuan Can , Bui Duy Hien , Tran Trung Hieu
Published: January 2025

Road traffic safety in Vietnam is one of the top social concerns due to the complicated situation of traffic accidents, requiring in-depth research to find appropriate solutions. Macroscopic evaluation of traffic safety is one of the effective ways to prevent and reduce road traffic accidents. The paper presents a new method based on an Equivalent Severity Score (ESS) to evaluate road traffic safety in an area using a geographic information system (GIS) tool, namely QGIS. The road traffic accident (RTA) data from 2021 to 2023 in Tuyen Quang province, Vietnam, was used to analyze and test this method. First, the RTA data was divided by the administrative units of Tuyen Quang, using several evaluation indicators, including the number of traffic accidents, fatalities, serious injuries, and slight injuries. Then, the ESS was determined based on these evaluation indicators to measure the seriousness of RTA across the administrative units. Finally, the ranking of road traffic safety of administrative units is presented by using QGIS software. From there, the traffic authorities can easily understand areas where RTA occurs more seriously and provide reasonable solutions. The results of the paper will help traffic authorities have more basis in making decisions related to solutions to solve traffic problems not only in Tuyen Quang province of Vietnam but also in other localities

Functionalization of Microcrystalline Cellulose through Integrated Sodium Periodate and TEMPO/Ozone Oxidations
Authors: Firdiana Bonita , Opaprakasit Pakorn
Published: January 2025

Cellulose modification has been a primary focus in developing bio-based degradable functional materials. In this study, an integrated approach combining sodium periodate (NaIO4) and TEMPO (2,2,6,6-tetramethylpiperidin-1-oxyl)-ozone oxidation process is employed to functionalize microcrystalline cellulose (MCC). The resulting materials in water-soluble and precipitate fractions were characterized to understand the influences of each oxidation method on the reaction mechanisms, structures, and physicochemical properties of the oxidized MCC samples. The results demonstrated that the combination of both methods resulted significantly in chemical structures, morphology, and surface reactivity of the samples. FTIR spectra showed an appearance of oxidized functional groups, i.e., carboxyl, ketone, and aldehydes, confirming a successful oxidation process. The use of ozone as a co-oxidant contributes positively to environmental aspects and process economics due to its availability and low cost. These findings illustrate the considerable potential of ozone utilization in improving cellulose properties for various applications. Consequently, the integrated approach offers an effective and sustainable solution for enhancing the quality and performance of cellulose, paving the way for further research and applications in the field of cellulose materials.

Enhancing Mechanical and Thermal Properties of Natural Rubber Grafted Poly(Ethyl Acrylate) Using Glutaraldehyde as a Curing Agent
Authors: Promsung Rawiporn , Lehman Nussana , Kalkornsurapranee Ekwipoo
Published: January 2025

Ethyl acrylate (EA) monomer was successfully grafted onto natural rubber (NR) via redox polymerization, which enhanced the grafting efficiency to 91%. The grafted-NR was clarified using ATR-FTIR. This study focuses on enhancing the mechanical and thermal properties of the grafted-NR vulcanized by using a low-temperature curing system of glutaraldehyde (GA). It was found that the mechanical properties of grafted-NR were superior to those ungrafted-NR, with a 35% increase in modulus, 145% increase in tensile strength, and 17% increase in elongation at break. Moreover, oil resistance properties and thermal stability of NR were significantly improved after graft copolymerization owing to the presence of functional groups in the molecular chain. It was also demonstrated that the grafted-NR exhibited improved crosslinking, elucidated through swelling and temperature scanning stress relaxation (TSSR) measurements. The relaxation behavior was evaluated through TSSR, revealing two significant peaks in chemical and physical relaxations. According to these findings, it can be summarized that the properties of grafted-NR improved by using a GA curing agent with several possibilities of interaction, including GA-rubber crosslinks, GA-protein crosslinks, GA-ester crosslinks, and polar-polar interactions facilitated by the presence of carbonyl groups on grafted-NR molecules. Therefore, this current work is beneficial for future flexible material applications requiring high mechanical properties, oil resistance, and thermal stability.

DEVELOPMENT OF A METAL 3D PRINTER USING A 3-UPU PARALLEL MANIPULATOR
Authors: Y. Nugman  , Zh. Turgunov  , R. Kaiyrov  , A. Mustafa  , A. Kawałek
Published: January 2025

This paper explores the potential application of a 3-UPU manipulator as a design for a metal 3D printer. To determine the working area of the 3-UPU manipulator, its inverse kinematics were investigated. Using the Denavit-Hartenberg method, the required lengths of the manipulator’s prismatic pairs were analytically calculated based on the coordinate system transformation matrices. The obtained results were verified by numerical methods in MATLAB program and the correctness of analytical solutions was confirmed. The study showed that the working area of the 3-UPU manipulator is 800x800x600 mm, which is large enough for metal 3D printers. This work area gives you the ability to print from small parts to large parts as well as body parts. The precise positioning and dexterity of the 3-point manipulator ensures sufficient precision in part production. This working area makes it possible to print from small parts to large parts as well as body parts. The positioning accuracy and dexterity of the 3UPU manipulator provides sufficient accuracy in part production. This accuracy of part fabrication reduces the post-processing time of parts by machining, resulting in less material consumption for chips and wear of cutting tools.
This research work can provide a scientific basis to enable the 3-UPU arm to be used in metal 3D printers. Future research following this work is planned to explore issues such as improving the dynamic model of the manipulator and increasing its efficiency by optimizing control algorithms.
Keywords: 3-UPU manipulator, additive manufacturing, working area, metal 3D printer, inverse kinematic.

Published: January 2025

The article presents the results of a study of changes in the properties of brass LAF 94-0.5-0.15 depending on the content of modifying components. Four samples of brass LAF 94-0.5-0.15 with the addition of aluminum and phosphorus modifiers were obtained by casting. The elemental composition of the obtained samples was determined by atomic emission spectroscopy and X-ray diffractometry. Maps of the distribution of modifiers on the surface of the obtained samples were compiled by electron microscopy. The microhardness of the samples was determined.
It was found that with an increase in the concentration of the modifier - aluminum, the microhardness of the samples decreases. By changing the content of the constituent components of brass and adding modifying elements to it, it is possible to optimize its reflective and mechanical properties. Homogeneous distribution of modifier elements is shown in a photograph in reflected electrons BSE, obtained with a scanning electron microscope, show that the sample is homogeneous and the modifying elements are distributed uniformly over the entire surface of the sample.
Keywords: brass, modifier, microhardness, reflectivity, X-ray diffractometry.

Este artículo aborda la importancia de una política criminal efectiva, para gestionar la delincuencia y garantizar la seguridad pública en la sociedad panameña. A través de una revisión crítica de las estrategias contemporáneas, se exploran las dimensiones teóricas y prácticas que sustentan las políticas públicas en este ámbito, haciendo énfasis en la necesidad de un enfoque multidimensional que combine prevención y represión. Además, se analizan experiencias internacionales y su aplicabilidad al contexto panameño, teniendo en cuenta los desafíos y las oportunidades para implementar políticas criminales que se adapten a las necesidades sociales del país.
La evolución de la política criminal en Panamá ha sido significativa, especialmente, desde la reforma del sistema penal en el 2008, que introdujo principios garantistas y un enfoque más humano en la administración de la justicia. La Ley 63 de 2008 trajo consigo cambios en el Código Penal y Procesal Penal, incorporando derechos humanos establecidos en convenios internacionales. Estos cambios transformaron el sistema inquisitivo hacia uno más equitativo y acorde con la realidad social panameña.
El artículo también subraya la necesidad de una inversión considerable en los recursos humanos y tecnológicos, así como de fomentar la colaboración entre el sistema de justicia penal, las instituciones gubernamentales y la sociedad civil. Solo mediante un esfuerzo conjunto se podrá avanzar hacia la creación de un entorno más seguro y justo. Llegamos a la conclusión que una política criminal efectiva debe equilibrar los enfoques de prevención, represión y rehabilitación, y estar adaptada a las particularidades socioeconómicas y culturales de Panamá.

Bailey truss has been widely used in temporary constructional structures of bridges and is reusable. In the service duration, the Bailey truss is commonly exposed to corrosion threats due to the failure of anticorrosion coatings, resulting in corrosion damage on members which induces degradation of its structural behavior. This paper presents an investigation on the corrosion damage of a Bailey truss that had been in service for 8 y in Northeast China. A total of 18 member segments were obtained from the chords, diagonals, and verticals of the Bailey truss, and were scanned by a three-dimensional (3D) laser scanner after clearing the paint and rust. Then reverse modeling was performed based on the 3D coordinates of the specimen surfaces. The surface topography was discussed for different members based on the separated roughness component, the residual thickness was analyzed for plates, and the residual cross-sectional area and moment of inertia about axes of the members were calculated and discussed. Coupon tests were performed on corroded specimens from chords, diagonals, and verticals to quantitatively analyze the degradation of corroded Bailey truss. It was found that the corrosion damage on flanges was more severe than that on webs, in terms of surface roughness and thickness loss. The corrosion status can be influenced by the microstructures and serving location. Upon the true values of the remaining cross sections, it was concluded that the chords, diagonals, and verticals of the Bailey truss all exhibited the largest loss ratio in the moment of inertia about y-axis and the smallest loss ratio in the cross-sectional area. The vertical member had the largest dispersion of average nominal loss rates, especially for the moment of inertia about y-axis, whose maximum and minimum values differed by 157.1%. A practical method for estimating the residual cross-sectional area and moment of inertia was validated. In addition, the engineering mechanical parameters (the elastic modulus, yield strength, ultimate strength, and the elongation after fracture) of each member show linear degradation. The mechanical parameters of the diagonal web are most affected by corrosion. There is 10% thickness loss in the chord web with up to 27% loss bearing capability in 8 y, and the factor of safety with respect to a reference parameter is lowered.
