L'operosa retorica di un intellettuale cittadino del XII secolo. Damnatio memoriae e altri espedienti politici nel Liber Pergaminus di Mosè del Brolo
Authors: De Angelis Gianmarco
Published: July 2024

The Liber Pergaminus by Moses del Brolo is certainly more than a laudatory description of the city. Foundation myths and exempla taken from Roman history are interwoven with an exaltation of the present time that has traditionally been read as a propagandistic support of the episcopate of Ambrogio Mozzi (1111/2-33). However, many of the points on which the last editor, Guglielmo Gorni, had drawn attention, implicitly soliciting further study, remain in the shadows: the reference is to the concrete and immediate occasions of the elaboration of the text of Moses, to its recipients and all the reades actually capable of decoding the language and contents of the proposal, of unravelling the thread that weaved a dense web of allusions, analogies, silences and removals. Reconstructing the gestation context of the Liber Pergaminus – and offering new reflections for a more stringent dating of the work –, the contribution intends to deal with these problems by showing the coherent design of the rhetoric of Moses, his industrious declination in the midst of the political conflict and in various connections with all the actors on the stage.

Hausa Ajami Poetry As A Vital Source For Historical Re-construction in Northern Nigeria
Authors: Shehu Danyaya Muhammad
Published: July 2024

The aim of this paper is to discuss Hausa Ajami poetry as a vital source for historical reconstruction in northern Nigeria. The paper from the introductory parts begins by analyzing how the jihad movement in the early decade of the 19th century resulted to the establishment of a large polity known as the Sokoto caliphate. The paper then proceeds to identify the intellectual characteristics of the caliphate leadership particularly, the Shehu who spearheaded the jihad movement and his disciples which led to a spectacular boost in literary production in diverse areas using different linguistic mechanisms; Arabic, Hausa and Fulfulde. Equally important was the discussion on the rationale behind the application of Ajami poetry during the period which inter alia aimed at simplifying the comprehension of Islamic tenets through the use of the local language. Relatively, the paper examines some of the areas of Hausa Ajami poetry that will be a very vital source to anyone dealing with any aspect of northern Nigerian history. The paper generally, revealed the dynamic nature on the intellectual reputation of the founding fathers of the Sokoto caliphate and some of their lieutenants. However, in its investigative approach the paper applied historical research technique by using both primary and secondary sources. The results of the investigation have inevitably shed more light on the intellectual contribution of the Sokoto ulama on the aspect of Ajami poetry.

Morreu e ressuscitou! Uma leitura foucaultiana sobre o caso do jogador de futebol Christian Eriksen
Authors: Oliveira Leonardo Hernandes de Souza , Machado Eduardo Pinto , Silva Alan Camargo
Published: July 2024

INTRODUÇÃO: A morte súbita caracteriza-se por uma parada cardiorrespiratória repentina que leva o praticante a óbito, em geral, quando alcança níveis altos de esforço físico. Em atletas de todas as idades, inclusive no futebol, nota-se um aumento do número de casos, mesmo diante de um investimento médico-tecnológico em estratégias preventivas. Este ensaio não desconsidera as implicações biológicas da morte súbita, mas visa investigá-la pela ótica das Ciências Humanas e Sociais, mais precisamente pelas perspectivas teórico-metodológicas de Michel Foucault e Nikolas Rose. Assim, objetivou-se analisar como especificamente a morte súbita do jogador de futebol Christian Eriksen pode revelar questões sobre as diferentes racionalidades de saúde e risco presentes nas práticas corporais e esportivas.DESENVOLVIMENTO: O encaminhamento teórico fundamentou-se nas teorizações (pós-) foucaultianas sobre controle e gestão dos corpos para pensar o viver e o morrer, principalmente nas interconexões entre espetáculo e biopolítica e no controle exercido por dispositivos artificiais e tecnológicos. Esta perspectiva teórica sobre morte súbita pela via biopolítica assume importância significativa para a Educação Física, pois entende-se que a regulação dos corpos em movimento não pode se resumir a lógica da racionalidade biomédica, incorporando outras sensibilidades discursivas sobre práticas de exercícios e saúde.CONCLUSÃO: Em suma, captou-se como as noções de vida-morte e os mecanismos médico-tecnológicos são regulados e gerenciados em prol de um sujeito de performance que, a todo instante, se torna autocontrolado sob verdades que modulam o biológico no contexto das práticas corporais e esportivas. A potência analítica deste ensaio leva as reflexões para além da mera consideração da “finitude da vida” ao examinar como estruturas de poder, controle e discursos moldam as compreensões da morte e as múltiplas práticas de cuidado em distintos espaços sociais.

Authors: R. Dinesh , R. Dilip Kumar , M. Jeevanantham , S. Sathishbabu , AKT. Sathishkumar
Published: July 2024

Conventional control methods, such as Proportional Integral Derivative (PID) control, have been extensively utilized for speed regulation in renewable energy wind turbine units. However, the limitations and disadvantages of PID, including difficulties in handling nonlinearities and uncertainties inherent in wind turbine dynamics, necessitate the exploration of alternative approaches. This research paper proposes the adoption of Iterative Learning Control (ILC) as an intelligent controller for addressing the shortcomings of PID. By exploiting the repetitive nature of wind turbine operation, ILC offers the potential to enhance speed regulation performance by iteratively refining control actions based on past experiences for advancing renewable energy. Through simulation studies, the effectiveness of ILC in improving the transient response and tracking accuracy of wind turbine units is demonstrated.

A Comparative Study of HPV Vaccine Acceptability Across Global North and South Countries: USA and Kenya
Authors: Nyaga Robert , Prince Adu Gyamfi
Published: July 2024

This study examined the HPV vaccine landscape in Kenya and the USA with a focus on if differences exist in the perceptions of HPV knowledge, vaccine attitudes, subjective norms, perceived behavioural control, and vaccine intention among students across country and gender. It also provides useful findings that can inform the design of persuasive health messages to promote the uptake of HPV vaccines among college students in Kenya and the USA. The study used surveys to recruit 1,033 participants (511 Kenyan and 522 USA students). The two-way MANOVA analysis revealed that the multivariate main effects showed no significant differences for gender, but the results revealed a significant main effect for the country. However, the interaction between gender and country of the participants was not significant. The univariate analysis revealed that the participants of the two countries had small significant differences in their subjective norms about HPV vaccination, and perceived behavioural control. The correlation analysis showed that HPV knowledge correlates with knowledge about the HPV vaccine and country, but not with gender. The results also revealed that knowledge about the HPV vaccine correlates with both gender and country. These results highlight the most salient predictors of vaccination intentions among college students that health communicators can focus on when designing and implementing HPV vaccination campaigns targeting students in Kenya and the USA.

Published: July 2024

The evolution of currency from barter systems to gold coins is a long journey in economic history, evolving from the simplest trading mechanism to complex financial systems. The paper points out the critical developments that took place in the shaping of international finance, focusing on the role of gold and the subsequent rise of the U.S. dollar as a global reserve currency. In the aftermath of World War II, there was an attempt to strengthen international institutions, such as the United Nations and the International Monetary Fund, and to establish the Bretton Woods system to anchor world currencies to the U.S. dollar, itself anchored to gold. The Bretton Woods system collapsed in the early 1970s after a quite successful beginning, giving way to floating exchange rates. The research explores the strategic role of the United States dollar since the end of World War II. It explains how the dollar became a global currency due to a sudden burst of trust in the U.S. economic system and its use as a requisite in international transactions. Moreover, gold coins and the gold standard also worked to help international trade and finance remain stable until the disruptions of World War I and the changes that followed in the global economic environment. It follows the historical development of the currency and reveals the foundational aspects on whose basis modern financial systems were laid, together with the lasting effects gold and the U.S. dollar had on international economic activity.

“You belong with me”- Taylor Swift event exclusivity and geopolitical tensions
Authors: Tham Aaron , Sin Harng Luh
Published: July 2024

Music concerts have been a common and popular event type for destinations, as artists take their performances to their audiences around the world. However, reports of destinations negotiating exclusive rights to events supported by governmental grants have emerged. Using the example of Taylor Swift’s allegedly exclusive contract to perform only in Singapore during the Eras Tour as a case study, this research note illuminates how music concerts are not just for entertainment purposes but are business opportunities to enhance a destination’s brand and stimulate tourism benefits and play important geopolitical roles in shaping diplomatic relationships and political goodwill. The Taylor Swift and Singapore case study also prompts future debates and discussions as to whether destinations ought to follow suit in terms of executing exclusive contracts for artists and major events, thereby shifting event management and artist/organizations’ expectations and possibly (over)politicizing events management amidst much talk of government support and subsidies.

Authors: Alydrus Nur Laela , Ka’bah  , Kasmuddin  , Prelly Loupatti
Published: July 2024

Enterotoxigenic Escherichia coli (ETEC) is a significant cause of diarrheal disease worldwide, particularly in children. The heat-labile toxin (LT) is a crucial virulence factor encoded by the LT gene. This study investigated the prevalence of ETEC LT gene expression in children with diarrhea in Makassar City, Indonesia. A cross-sectional study was conducted from January 2023 to December 2023. Rectal swabs were collected from children under five years of age presenting with diarrhea at outpatient clinics in Makassar. DNA was extracted, and the presence of the ETEC LT gene was detected using polymerase chain reaction (PCR). Demographic and clinical data were collected via questionnaires. The ETEC LT gene was detected in 81 (18%) children. The prevalence was significantly higher in children under one year of age (51%) compared to older age groups. ETEC LT positive children were more likely to experience vomiting and fever. ETEC expressing the LT gene contributes to a significant proportion of pediatric diarrhea cases in Makassar. The higher prevalence in younger children highlights the vulnerability of this age group. These findings emphasize the need for improved sanitation and hygiene practices to reduce ETEC transmission.

Published: July 2024

This field study was carried out to reveal the implementation of computational thinking in learning Natural Sciences and Physics in the Independent Curriculum. The study was conducted in Garut Regency targeting science, physics and ICT teachers in schools that have implemented the Independent Curriculum. The number of respondents involved was 112 teachers who were selected using the cluster sampling method. Respondents consisted of 57.1% elementary school teachers, 31.3% middle school teachers, and 11.6% high school/equivalent teachers. The instruments used include questionnaires, observation sheets, and document analysis sheets. Data analysis was carried out using triangulation techniques from research data. The research results show that conceptually teachers still do not understand computational thinking. Even though some teachers are aware of the emphasis on implementing computational thinking in the independent curriculum, the documents for planning and implementing learning in the classroom still do not show this implementation. These results can be used as a basis for conducting training and assistance to science and physics teachers in implementing computational thinking in learning.

In response to the challenges posed by the recent pandemic on traditional farming in Malaysia, this paper proposes DuWIMS, an innovative smart irrigation system that integrates a modern web interface with an IoT-based system. Utilizing an array of sensors for real-time data collection, the system enhances irrigation efficiency through a dual-mode operation: manual remote control and automated irrigation via a fuzzy logic model. This system, tested on a durian farm in Kedah, Malaysia, significantly reduced irrigation time from two hours to approximately 50 minutes for 65 trees and decreased water usage by about 25%. Furthermore, durian trees irrigated with this system exhibited improved growth compared to those under traditional irrigation methods. Operational efficiency was bolstered with remote irrigation control and reliable performance, as evidenced by no system downtime over a three-month period. The deployment of the fuzzy logic model on a cloud server, serving as a backend API, also proved cost-effective by negating the need for on-site computing units. These findings underscore the potential of DuWIMS to revolutionize agricultural practices, particularly in challenging times, by optimizing resource usage and promoting sustainable farming.

Adverse Environmental and Economic Impacts of Solar and Wind Energy
Authors: Rahman Md. Zahidur
Published: July 2024

The negative effects of traditional energy sources have long been the center of concern worldwide. Contrarily, alternative energy sources, particularly those that are renewable, such as solar and wind power, have always had a positive reputation. It is often thought that solar and wind energy are environmentally friendly and economically cheap. However, these energies also create problems that may be overlooked or unnoticed. The current research aims to illustrate the negative environmental effects of solar and wind energy, as well as describe the economic disadvantages of renewable power plants. To accomplish this paper, data, and evidence from several research papers were analyzed. It was discovered that renewable energy may cause biodiversity loss and create natural disasters. It is also responsible for microclimate change. In addition, renewable energy plants are not economically beneficial both in the long and short run. This paper should make people and policymakers aware before launching renewable energy projects.

Authors: Mohamed Noor Nusaiba
Published: July 2024

This study has examined the influence of real rates of interest and inflation on the economic development of Ethiopia. The study used analysis of time series data and chose to collect samples of 42 years, covering the period from 1981 to 2022. The research used data gathered from the World Bank's archive as well as the International Monetary Fund’s (IMF) Global Economic Outlook database. In addition, the research used an econometric analysis methodology by using the auto-regressive distributed lag (ARDL) model and its related Error Correction (ECM) Model to determine the long-run and short-run correlations between the variables. The study used the Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root tests to determine the stationarity or non-stationarity of the time series data variables in the research, as well as their integration levels. The research used economic growth (GDP) as the dependent variable. The E-Views 12th edition software package facilitated the use of various time series data analysis methodologies and tests. The research has identified both short and long-term cointegration links among all the variables examined in this study. The findings revealed a statistically significant inverse correlation amongst real rates of interest and Ethiopia's growth in economy over time, seen in both the long term and the short term. In the long term, inflation has a clear and substantial impact on Ethiopia's economic development.

Published: July 2024

Terminal Aerodrome Forecasts (TAFs) are essential components of aviation meteorology, providing critical information for flight safety and operational decision-making. This study conducts a comprehensive analysis of TAF for European airports during the years 2022 and 2023, leveraging Python functions accessible via a dedicated GitHub repository. The complexity inherent in TAF, characterized by diverse change groups, header formats, and regional variations, presents challenges for accurate interpretation. The analysis focuses on key parameters within TAF, including the count of corrected messages and the frequency and types of change groups. The count of corrected messages serves as a metric for evaluating the quality of service provided, while the examination of change group utilization reveals distinct patterns and tendencies specific to each airport. The findings underscore the significance of regional regulations, meteorologist decision-making, and adherence to International Civil Aviation Organization (ICAO) standards in shaping TAF. The GitHub repository and associated Python functions presented in this study provide valuable resources for meteorologists, researchers, and aviation personnel to conduct in-depth analyses and derive insights from TAF. Ultimately, this study identifies local differences and inconsistencies in the publication of TAF, laying the groundwork for enhancing their consistency and uniformity.
IMS CUBE, A NEW RISK MODEL FOR INTEGRATED MANAGEMENT SYSTEMS IN AVIATION
Authors: Meeûs Joeri , Dewulf Wouter , Macário Rosário
Published: July 2024

Airlines have implemented various management systems to avoid different risks but without considering interoperability or integration. This results in a lack of a holistic view and a counterproductive and isolated approach to managing different risks. Therefore, this article proposes a newly designed model to have an integrated system for airlines to ensure interoperability and demonstrate the added value of such a model. The model is based on a survey outcome which confirmed the need for interoperability amongst different management systems. The developed model creates a language for key processes in different management systems, enabling different management systems to create interoperability. The language consists of 3 components used by the different systems. Adding a process to integrate all the different systems provides a holistic view of how each management system works together by providing focus points for the different risks airlines face. Together with the concept of the IMS cube, a new practical model is developed and provides new insights into the different management systems, which remain undetected when looking at management systems individually. It is concluded that a holistic risk profile assists airlines in making decisions which impact multiple management systems rather than individual management systems.

Published: July 2024

As part of our variable star follow-up program, we have examined a number of stars from the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey. Using a combination of our own data, ATLAS data, and other archival data, we confirmed the published periods and established a baseline ephemeris for each star. This initial sample of six stars are from the PUL or mono-periodic set from the ATLAS survey. Our determined periods agreed well with the published values. Five targets were found to be high amplitude δ Scuti variables (HADS), and one a low-amplitude δ Scuti (LADS). Beyond the primary period we examined the frequency content, Q value, position in the PL relation, and position within the instability strip of each object. We found ATO J070.9950+37.4038 to be the most complex target. The frequency content is likely a set of nonradial pulsations. ATO J328.8034+58.0406 is a multiperiodic HADS variable that is pulsating in the first and second overtones. ATO 345.4240+42.0479 was found to be a simple HADS monoperiodic fundamental pulsator. In the case of ATO J086.0780+30.3287, we found a strong fundamental pulsation with many harmonics and a weaker first overtone pulsation. We classify ATO J086.0780+30.3287 as a HADS. ATO J077.6090+36.5619 was found to be an interesting case of a monoperiodic star that appears to be pulsating in the third overtone. The lower amplitude for this target would put it in the LADS group. ATO J045.8159+46.0090 was found to be a multiperiodic HADS pulsating in the first and second overtones.
